Edgar Filing: NATIONAL GRID PLC

Updates will continue to be provided to the Board on a regular basis, as appropriate.

Risk workshop. The Board participated in a risk workshop that included an update on the changes introduced by the New Code, the annual risk appetite review and an in-depth review of the current risk profile of the Company. At the workshop, it was agreed that the evaluation of risk appetite should permeate through to the evaluation of all new projects and further work was required in relation to the risk appetite definitions and the Company’s risk profile.

Safety updates. Safety is discussed at every Board meeting. The Board receives safety updates in the Chief Executive’s report and supplementary to this, the Safety, Environment and Health (SEH) Committee chairman provides an oral summary of matters considered at Committee meetings.

Annual talent management review. The Board noted the progress of the development of capacity, capability and the talent pipeline and the accelerated development programme, which had resulted in long-term career plans being put in place and graduates moving through the Company more speedily than in the past.

Examples of expected Board focus for next year:

● regular reviews of safety activities;

● mid-term review of our progress and performance under

   RIIO;

● continued detailed review of strategy and financing;

● key US rate case filings;

● regulatory compliance;

● implications of the Integrated Transmission Planning and

   Regulation project on our activities;

● review of the political situation following the UK general

   election and the impact on energy policy in the UK and EU;

● refined reporting to strengthen our assessment and

   monitoring of internal control and risk management

   following the updates to the New Code;

● reviews into UK and US regulation and the major projects

   in the UK;

● the 2015 UK Winter Outlook; and

● results of the 2015 employee opinion survey.

Board composition

The successful delivery of our strategy depends upon attracting and retaining the right talent. This starts with having a high-quality Board. Balance is an important requirement for the composition of the Board, not only in terms of the number of Executive and Non-executive Directors, but also in terms of expertise and backgrounds.

While traditional diversity criteria such as gender and ethnicity are important, we also value diversity of skills, experience, knowledge and thinking styles. You can read about our Board diversity policy in the Nominations Committee report on page 58.

Following the conclusion of the 2014 AGM we said goodbye to Maria Richter and Nick Winser from the Board. Additionally, Philip Aiken stepped down with effect from 25 February 2015 and Tom King from 31 March 2015. We welcomed John Pettigrew as Executive Director, UK on 1 April 2014 and Dean Seavers as Executive Director, US with effect from 1 April 2015.

Director induction and development

As our internal and external business environment changes, it is important to make sure that Directors’ skills and knowledge are refreshed and updated regularly. Our Chairman is responsible for the ongoing development of all Directors.

To strengthen the Directors’ knowledge and understanding of the Company, Board meetings regularly include updates and briefings on specific aspects of the Company’s activities. In January the Board participated in a strategy session; see the previous page.

Updates on corporate governance and regulatory matters are also provided at Board meetings, with details of development and training opportunities for Directors available in our online document library.

Additionally, the Non-executive Directors are expected to visit at least one operational site annually. In 2014 this included visits in the UK to the LNG terminal on the Isle of Grain, the gas distribution control centre, and the customer centre and emergency dispatch based in Hinckley. And in the US, the Directors met with management of the Independent System Operator New England and visited the Brooklyn Queens Interconnect project, a Long Island power station, and other major projects and stakeholders in New York City. Visits to the Long Island power plants and the Western Link project are among those planned for 2015. These visits provide the opportunity for Directors to meet local management teams and discuss aspects of the business with employees.

With the agreement of the Board, Executive Directors gain experience of other companies’ operations, governance frameworks and boardroom dynamics through non-executive appointments. The fees for these positions are retained by the individual. See page 67 for more details.

The Board in action

Thinking styles session

Following on from the thinking styles session supported by an external consultant held in 2014, the Board undertook a second session in February 2015.

The session was specifically designed to encourage diverse thinking within the boardroom. New Board members were invited to give their thoughts on how the Company operates. The session covered the benefits of thinking styles for different types of discussion and ways in which the diverse capability that exists within the Board could be harnessed to maximise its effectiveness. The session also reviewed the progress made since the 2014 session.

A thinking styles action has been included in the action plan resulting from this year’s Board evaluation; see page 47.

Directors’ induction programme

Following Dean’s appointment to the Board, the Chairman, Chief Executive and Group General Counsel & Company Secretary arranged a comprehensive induction programme. The programme has been tailored based on his experience and background and the requirements of his role.

Dean’s induction programme has included a meeting with our external legal advisors to discuss the duties and requirements of being a listed company director in the UK. He has also held one-to-one meetings with his fellow Directors and senior management, and attended visits to operational sites to build his understanding of the Company and its businesses in the UK and US. His induction will continue over the coming months and will include further operational site visits.

Details of Therese and John’s induction programmes were provided in last year’s Annual Report and Accounts. These programmes have continued over the year.

		Strategic Report
		Chairman’s statement
		It’s been a challenging year for the energy sector. Energy policies in the UK and US have continued to evolve against a backdrop of political uncertainty, seeking an acceptable balance between affordability to consumers, security of supply and sustainability considerations.


		In focus:		In the UK, we saw debate around the cost of living lead to a sharper focus on the costs of energy and the competitiveness of energy markets. This focus has included an Energy and Climate Change Select Committee inquiry into energy network costs, as well as an investigation by the Competition and Markets Authority into the supply and acquisition of energy in Great Britain. In the UK, Electricity Market Reform
		The Board is proposing a recommended full-year dividend of 42.87p (2013/14: 42.03p)
				(EMR) was implemented successfully, and we saw developments in significant interconnector projects (see page 27). In the US, there were mid-term US congressional and gubernatorial elections and debate continued on essential infrastructure, resilience and sustainability.
				Transparency
				In January we announced our decision to stop publishing formal Interim Management Statements (IMSs), following the changes in legislation that removed this requirement. Mandatory requirements to publish information can frequently provide an unnecessary focus on matters of little relevance to a long-term business such as National Grid.
				Alongside our major announcements at the half year and full year we will continue to provide updates covering market and Company developments.
				We also continue to provide commentary on both our IFRS reported results and underlying economic (regulatory) performance, including reconciliations between the key metrics for both results. To help explain this more fully, we have increased the commentary on our regulatory performance on page 23, and have included further analysis of our regulatory performance by segment on page 100. We support the development of an accounting standard for rate-regulated activities, which would reduce the need for additional explanations of our results, and submitted a response to the IASB’s project in January this year.
				Dividend
				The Board has recommended an increase in the final dividend to 28.16 pence per ordinary share ($2.1866 per American Depositary Share). If approved, this will bring the full-year dividend to 42.87 pence per ordinary share ($3.3584 per American Depositary Share), an increase of 2.0% over the 42.03 pence per ordinary share in respect of the financial year ending 31 March 2014.
				In August 2014 we began a share buyback programme designed to operate alongside our scrip dividend option, which we offered for the interim dividend and will offer again for the full-year dividend. The buyback programme, which operates under authorities granted at our 2014 AGM, is designed to balance shareholders’ appetite for the scrip dividend option with our desire to operate an efficient balance sheet with appropriate leverage.
				Effective governance
				In July 2014, John Pettigrew, who joined the Board in April 2014, became Executive Director, UK and Nick Winser and Maria Richter both stepped down from the Board.


Philip Aiken stepped down from the Board in February 2015 before his appointment as Balfour Beatty’s new Chairman. He was a National Grid Non-executive Director for six years and played an important role in chairing our Safety, Environment and Health Committee. Following Philip’s departure, Paul Golby was appointed as chairman of the Safety, Environment and Health Committee, as well as a member of the Audit Committee. Paul remains a member of the Nominations and Remuneration Committees. Tom King stepped down from the Board and left the Company on 31 March 2015. He was succeeded by Dean Seavers, who joined the Company in December 2014 and, following a thorough handover, joined the Board as Executive Director, US with effect from 1 April 2015. John and Dean’s appointments bring fresh perspective, experience and challenge to our Board. Dean joined us after a career that has included business leadership roles of major divisions within GE, United Technologies and Tyco. In particular, he has led major change and performance improvement programmes that have improved operational efficiency and customer satisfaction – important priorities for our US business. I would like to thank Nick, Tom, Philip and Maria for their commitment to the Board and the very valuable contribution they have made. National Grid’s UK regulated entities appointed Catherine Bell and Clive Elphick as Non-executive Directors with effect from 1 April 2014. The appointment of two Non-executive Directors is a new requirement promoted by Ofgem, which has termed the appointments Sufficiently Independent Directors. The arrangements are designed to enhance the financial ring-fencing conditions that already exist in the companies’ licences. Responsible business At National Grid, we believe that what we do and how we do it are equally important. In July 2014, National Grid was named Responsible Business of the Year 2014 by Business in the Community (BITC). To win this award we had to demonstrate how we operate responsibly in everything we do, and how we are improving the outcomes for society through our work.				As you can read on page 17, we are adding new KPIs to our reporting, so we can more fully reflect the issues that really matter to the Company and our stakeholders. For our 2014/15 Report, we have included workforce diversity as a new KPI and you can read more about our approach to this on pages 18 and 19, as well as progress in relation to our Board diversity policy on page 58. You can find more information about our approach to being a responsible business, including our Total Contribution Report, on our website. Looking ahead We will face both opportunities and challenges over the coming year. For example, in the UK Ofgem has concluded its Integrated Transmission Planning and Regulation project. As part of this, the System Operator is expected to undertake a number of new advisory roles. We have a long track record in successfully managing potential conflicts of interest from our System Operator role and will work closely with Ofgem to make sure this continues. In the US we expect to file important applications for new rate plans – you can read more about this on page 169. We will continue to work with policymakers, customers, and stakeholders to transform the energy industry through initiatives in Massachusetts, New York, and Rhode Island (see pages 33 to 35). We must adapt to developments in corporate governance requirements. For example, the updated UK Corporate Governance Code enhances the quality of information investors can expect to receive about the long-term health and strategy of listed companies, and encourages companies to be more transparent about risk management and internal control. Finally, I am confident that our people will continue to help make National Grid a company we can all be proud of and I thank all our employees for their hard work and commitment to our success. Sir Peter Gershon

I was delighted that the judging panel commended our long-term vision based on trust and connectivity. They noted our foresight in using technology and innovation to develop solutions that protect our employees, customers and wider society; and recognised our appetite to inspire others.
In the UK, we are in discussions with the Living Wage Foundation about the opportunity to become a fully accredited Living Wage employer. We can confirm that all our UK employees fulfil the criteria for accreditation. We are also working through the Living Wage Charter to understand the impact it would have on our supply chain, including the companies our suppliers use as sub-contractors, should we decide to adopt it.

		Strategic Report
		Chief Executive’s review
		I’m really proud of our performance this year. Overall, our businesses in both the UK and US achieved a strong operating performance.


		In focus:		In the UK, there has been a lot of public focus on how secure and reliable our energy supply is, particularly on tighter margins between electricity supply and demand in the winter. Despite tighter margins than previous years, we were able to operate the system without calling upon our additional reserve. This was because of stronger than expected plant availability, mild weather,
		Employee engagement score 75% (2013/14: 71%)
				healthy wind output and consistent interconnector imports from France and the Netherlands. We also tendered the two new balancing services for additional reserves of supply. Although these additional reserves were not used, this was a sensible precaution in case of colder weather or a series of unexpected plant shutdowns.
				In the US, we saw an extremely harsh and prolonged period of plunging temperatures and record levels of snowfall in parts of New England, particularly in February and March. Again, our network resilience held up well. We have invested millions of dollars in both our electricity and gas infrastructure to improve resilience and help reduce the impact of service interruptions.
				In December 2014 we received an award for excellence in energy efficiency from Platts Global Energy. Platts commended us for ongoing initiatives to upgrade equipment, reduce emissions, and improve safety and network efficiency. And in March 2015, the Edison Electric Institute presented us with its Emergency Recovery Award for our power restoration efforts following the severe ice storm in northern New York in December 2013.
				Safety Safety remains a hugely important priority for us. Regrettably, there were two fatalities during the year – a member of the public in the UK who fell when climbing on one of our pipelines, and a contractor at our Rhode Island gas distribution business. Despite these incidents, we achieved our best-ever Group safety performance during 2014/15. We can never be complacent about our performance and must continually strive to improve.
				Our operations We have continued to provide good value and reliability for customers while keeping our element of bills as low as possible.
				We are totally committed to providing the best value we can for our customers, investors and other stakeholders, so we’re working hard to make sure we are being as efficient as possible in everything we do. To help achieve this, we have continued to develop a way of working we call ‘Performance Excellence’, which you can read about on page 27. We also reorganised our UK business to increase clarity around what we do and who is accountable.
				In the US, we finally completed the stabilisation work on our new financial systems (see page 34). This fixed a number of long-standing problems, such as inefficient payroll processing, which had previously required expensive manual interventions. Long term,

the robust data we can produce with the new systems is an essential foundation to the future performance improvements and regulatory filings that we need for profitable growth in the US.

It is increasingly recognised in the US that investment levels in some areas will need to rise compared with the earlier part of this decade, and we have seen increased activity this year, making it our highest ever year of US investment.

In December 2014 the NYPSC approved $200 million gas infrastructure investment in Long Island to speed up the replacement of ageing pipe and extend the use of natural gas to more customers.

The NYPSC also published the results of the regulatory audit of our New York gas companies. These audits are a regular feature of the New York regulatory process. The audit was broadly supportive of our performance and structure and, as is usual, made some helpful recommendations for further improvement. We have responded with an implementation plan to provide these benefits on behalf of New York customers.

As you can read on pages 18 and 19, our customer satisfaction scores were mixed. We exceeded our UK electricity and gas transmission targets. However, we did not meet our US targets and I recognise this is an area in which we must improve.

Responsible Business of the Year

As Sir Peter has described in his statement, National Grid was named Responsible Business of the Year 2014, which is BITC’s top award. I am extremely proud of this achievement, which is terrific recognition of how we are running a responsible and sustainable business, bringing long-term benefits to society. Although BITC is a UK body, the award was given to the entire Company and recognises the excellent work we’re doing across our entire service area in the UK and US.

For example, in the UK we are completing a test line for the T-pylon at our training academy. It is smaller than the existing lattice towers and provides communities with added choice. Our property business entered into a new arrangement with the Berkeley Group to develop a number of our sites in London and the surrounding area. The first phase of investments could lead to the development of over 7,000 new homes, including affordable housing, alongside schools and public spaces.

Our EmployAbility programme provides supported internship opportunities for students with additional learning needs. Now into its second year, we have extended the programme and will continue to do this across more of our UK sites.

We are helping schools, parents and children see engineering as a modern, dynamic, desirable sector with a great future. Our careers education programmes in the UK include Careers Lab, an initiative we developed that has now been taken up by BITC. It links working professionals with schools

to bring the world of work to life for secondary school children. Our US initiatives include partnering with seven local community colleges to deliver energy utility technology training programmes that are designed to equip people for jobs in the energy industry. We are doing a great deal of work in this area, as you can read on page 24.

All this is business as usual for us – the BITC recognition is not the result of any special new initiative we have done to win the award. But it would not have been possible without the efforts of our employees. I was delighted to see that the results of our 2015 employee opinion survey – a good measure of how satisfied employees are with their employer – included an engagement score of 75% – our highest since we started conducting Group-wide employee opinion surveys.

I would like to thank all our people for making a positive impact, through their work for National Grid, their volunteering and fundraising achievements, and by getting involved in activities that really matter to us and to society.

Priorities for 2015/16

Safety: continue to build on our strong performance so we can achieve a consistent world-class safety performance;

Customers and stakeholders: improve the service we provide for our customers and continue to build trust among our stakeholders;

Performance Excellence: focus on being efficient in our end-to-end processes so we can continue to improve our overall performance and efficiency; and

Regulatory filings: prepare and file applications for new rate plans in New York, Long Island and Massachusetts.

NATIONAL GRID ANNUAL REPORT AND ACCOUNTS 2014/15				05


		Strategic Report
		Operating environment
		The UK economy has been recovering steadily in the past year, with 2.6% economic growth, falling unemployment and falling inflation.

Growth in the fourth quarter of 2014, however, dropped to 0.5% as sluggish eurozone growth depressed exports and wider geopolitical events increased the perceived risk of investment. In the US, employment levels have continued to rise. The Federal Reserve ended its quantitative easing programme of bond purchases, though treasury yields continue to be at or near

historical lows. GDP increased 2.4% in 2014, although growth in the first quarter of 2015 was only 0.2%.

Below, we highlight our main market drivers and the impact they have on our business.


		Market driver		Impact
		Changing energy mix Changing fuel costs and environmental programmes are affecting traditional electricity generation UK In February 2015 DECC announced the results of the first Contracts for Difference (CfD) auction allocation rounds, with wind technology making up the bulk of contracted generation. Continued support for solar PV through Feed in Tariffs (FiTs) and the Renewables Obligation contributed to growth in installed solar PV. Older fossil fuel plants continue to face the challenge of environmental regulations while the new nuclear plant at Hinkley received State Aid approval from the European Commission in October 2014. US In the US, shale gas development has continued to keep national wholesale prices low. Environmental Protection Agency regulations have led to generator retirements or increased costs for compliance. Renewables are growing their share of electricity generation and account for a significant amount of newly installed capacity. Distributed generation, such as rooftop solar, has grown substantially in our service territory.		This could lead to significant network investment opportunities UK Increasing deployment of large-scale wind, large-scale solar PV and nuclear will require more investment in transmission networks to connect new plant and reinforce the network. Variable output from solar PV and wind makes balancing demand and supply more challenging. More interconnection between the UK and adjacent European markets will deliver net benefits to the UK. US Lower national wholesale gas prices have increased the amount of gas used for electric generation, causing constraints into the northeast US. Oil to gas conversions will continue as gas maintains its price advantage. New interstate gas pipeline capacity is needed to overcome growing gas demand. The electric transmission system will need upgrades and rebalancing due to generation retirements and to connect new renewable sources. Increasing amounts of distributed generation, particularly solar, will require investment in the electric distribution network.
		Energy policy
		Sustainability, security of supply and affordability underpin EU policy Against a difficult economic and financial background, the EU’s energy policy is underpinned by sustainability, security of supply and affordability. In October 2014 the EU heads of state agreed the EU’s 2030 Climate Change and Energy Framework. This includes a 40% reduction target for carbon emissions, alongside other objectives for renewables, energy efficiency and interconnections. Negotiations for a new international agreement on climate change continued at the twentieth session of the Conference of Parties (COP20) in Lima in December 2014. Nations are looking to the Paris worldwide conference in 2015 as the next opportunity to work out a new climate change deal. Finally, the creation of a ‘genuine energy union’ was highlighted as one of the main priorities of the new European Commission, which took office in November 2014.		Policy decisions can affect our investment needs and compliance obligations Greater levels of market integration, interconnection and renewable generation are fundamental to achieving the EU’s policy objectives. While European developments present challenges, the significant level of investment required will create opportunities for growth. For example, potential future interconnector opportunities include connections between the UK and France, Ireland, Denmark and Iceland. Such opportunities would help the EU achieve its interconnection targets. See page 27 for more information about our interconnector projects.
		UK energy policies are attracting investment and there is significant political focus on reducing costs for consumers Energy policy continues to evolve from the Climate Change Act 2008, which commits the UK Government to reducing UK greenhouse gas emissions to at least 80% lower than a 1990 baseline by 2050. The Energy Act 2013 implements the main aspects of EMR, and puts in place measures to attract the investment needed. The run-up to the General Election in May 2015, saw a sharp focus on the costs of energy and the competitiveness of energy markets.		National Grid is central to the delivery of EMR and active on driving down costs National Grid has been performing its role as delivery body for the Government on EMR, as described on page 39. The focus on the cost of energy is important to National Grid. We are working hard to highlight to our stakeholders how the RIIO regulatory framework is helping us to reduce costs for consumers while creating incentives for vital investment.


06


		Market driver				Impact
		US policy is evolving to meet environmental and energy diversity goals In the US, many federal level developments have been through federal agency regulations and Presidential executive orders. At a state level, energy policy continues to evolve in the northeastern US, driven by interest in promoting energy efficiency, maintaining reliability and deploying renewable technologies that help meet environmental and energy diversity goals.				Options for increased renewable and distributed generation are being explored In the US, the impact on natural gas dependency has resulted in an evaluation of the best way of increasing fuel diversity through renewable and distributed generation resources. We continue to support movement towards a clean energy economy; and support additional measures to increase America’s energy productivity.
		Regulation
		Infrastructure investment needs must be balanced with affordability				We must accommodate customers’ cost concerns and also provide safe, up-to-date systems
		Regulators acknowledge that there is a significant need for infrastructure investment. However, affordability continues to be a primary concern. Ageing gas mains can be riskier to use and can contribute to greenhouse gas emissions through leaks. Regulators and policymakers are asking utilities to put plans in place to strengthen their networks’ ability to withstand the effects of severe weather.				We must accommodate our customers’ affordability concerns while fulfilling our obligations to provide safe and reliable services and upgrading our systems. Investment is required for new connections, to meet the challenges of changing supply and demand patterns, and to replace ageing infrastructure in the UK and US.
		UK regulators want greater efficiency and innovation In the UK, the regulatory focus during the year has been on the RIIO price controls which give greater focus to incentives and innovation than the previous regulatory regime. We continue to be engaged in the debate on the regulatory approach to electricity transmission investment, stemming from the projected increase in offshore wind generation and interconnection.				This is driving them to favour more market competition In the UK, competition is already in place for offshore development and Ofgem has stated its intent to retain the option of using greater competition for certain large onshore projects. For more information about network efficiency and innovation, see pages 27 to 31.
		In the UK, Ofgem is reviewing the arrangements for planning and delivering Britain’s transmission networks We are facing new challenges from an ageing infrastructure and a changing energy mix. Technical developments and innovation also mean that there could be opportunities to coordinate and integrate those investments. The Integrated Transmission Planning and Regulation (ITPR) project is looking at long-term challenges such as ageing infrastructure, the changing energy mix, technical developments and innovation, to assess whether the regulatory arrangements currently in place are sufficient to ensure coordination and efficiency in the future planning of electricity transmission.				We need to make sure the network is planned in an economic, efficient and coordinated way Ofgem has proposed enhancing our role as System Operator (SO) so that the SO has a greater role in system planning. No organisation is currently responsible for taking an overarching view of system development, so opportunities for coordination can potentially be missed. We are working with Ofgem to develop the framework for how the system will be planned and how assets will be managed.
		US regulators are focused on system modernisation and integration of new distributed energy resources State officials in Massachusetts and New York have approved gas system investment programmes to accelerate replacement of ageing infrastructure. The Massachusetts Grid Modernization proceeding and New York’s Reforming the Energy Vision effort both focus on deploying advanced electric grid capabilities to improve reliability, more fully exploit distributed energy resources, and provide new opportunities for customers to control their energy use.				Investments to modernise networks and integrate distributed resources will offer new options and value to customers We are expanding gas system enhancement investment programmes and are developing electric grid modernisation plans. Through our regulatory efforts and stakeholder engagement we are seeking to create a regulatory framework that integrates distributed energy resources into the electric grid in a way that is cost effective and delivers benefits to customers.
		In the US, FERC is reforming transmission planning and promoting competition in the transmission industry FERC issued Order 1000 in 2011 to improve transmission planning and increase competition in the transmission industry. Policies to comply with the Order took effect in New York and New England in 2014 and 2015, respectively.				Competitive transmission planning provides opportunities for us Order 1000 has opened our service territory to competition from non-incumbent transmission developers and also created opportunities for us to compete for transmission projects outside of our current geographic footprint.
		Innovation and technology
		Performance improvements and cost declines have led to continued growth in new technologies Distributed generation of solar power has grown significantly due to price declines and tax incentives. Energy storage is growing in the US as certain states set goals and other utilities announce investment plans for storage capacity. The UK hit a record high for wind generation in 2014 of 28 terawatt hours (TWh), 15% greater than the previous year. Plug-in electric vehicle sales in the US and worldwide grew, even as gasoline prices dropped throughout the past year.				Further investment in electricity distribution networks may be necessary to integrate these new technologies Investment in renewable energy continues to grow. Regulatory proceedings are underway to enhance the value of distributed resources to the grid and give customers more control over their energy use. These could require significant network investment in order to integrate new and variable resources and provide customers with more information on their usage.

What we do – Electricity

The electricity industry connects generation sources to homes and businesses through transmission and distribution networks. Companies that pay to use transmission networks buy electricity from generators and sell it to consumers.


		System operator As system operator (SO) for England and Wales, we coordinate and direct electricity flows onto and over the transmission system, balancing generation supply and user demand. Where necessary, we pay sources of supply and demand to increase or decrease their generation or usage. We have the same role for the two high voltage electricity transmission networks in Scotland and we are SO for the offshore electricity transmission regime. Our charges for SO services in the UK are subject to a price control approved by Ofgem. System users pay us for connection, for using the system and balancing services. As electricity transmission SO, our price control includes incentives to minimise the costs and associated risks of balancing the system through buying and selling energy, as well as procuring balancing services from industry participants. In the US, similar services are provided by independent system operators.				will deliver significant benefits to consumers. These include opportunities for interconnection with Iceland, Denmark and a further link with France.
						We also jointly own and operate a 224 kilometre interconnector between New England in the US and Canada.
						We sell capacity on our UK interconnectors through auctions and on our US interconnector through wholesale markets and bilateral contracts.
						Transmission systems generally include overhead lines, underground cables and substations. They connect generation and interconnectors to the distribution system.
						We own and operate the transmission network in England and Wales. We operate but do not own the Scottish networks. We are also working in a joint venture with Scottish Power Transmission to construct an interconnector to reinforce the GB transmission system between Scotland and England and Wales.
		Generation is the production of electricity from fossil fuel and nuclear power stations, as well as renewable sources such as wind and solar. In the US, we own and operate 50 fossil fuel-powered stations on Long Island and 4.6 MW of solar generation in Massachusetts. We do not own or operate any electricity generation in the UK. We sell the electricity generated by our plants on Long Island to LIPA under a long-term power supply agreement. The contract allows us to recover our efficient operating costs and provides a return on equity on our investment in the generation assets. For solar generation, we recover our costs and a reasonable return from customers in Massachusetts through a solar cost adjustment factor. This is added to the electricity rate, net of revenues earned from the solar assets. Transmission grids are often interconnected so that energy can flow from one country or region to another. This helps provide a safe, secure, reliable and affordable energy supply for citizens and society across the region. Interconnectors also allow power suppliers to sell their energy to customers in other countries. Great Britain is linked via interconnectors with France, Ireland, Northern Ireland and The Netherlands. National Grid owns part of the interconnectors with France and The Netherlands. We are also now entering the construction phase for two new interconnectors, between the UK and Belgium and Norway. We are continuing to work on developing additional interconnector projects, which we believe				In the US, we jointly own and operate transmission facilities spanning upstate New York, Massachusetts, New Hampshire, Rhode Island and Vermont. Distribution systems carry lower voltages than transmission systems over networks of overhead lines, underground cables and substations. They take over the role of transporting electricity from the transmission network, and deliver it to consumers at a voltage they can use. We do not own or operate electricity distribution networks in the UK. In the US, our distribution networks serve around 3.5 million customers in upstate New York, Massachusetts and Rhode Island. The supply of electricity involves buying electricity and selling it on to customers. It also involves customer services, billing and the collection of customer accounts. We do not sell electricity to consumers in the UK. All our customers in the US can select a competitive supplier for the supply component of electricity utility services. Where customers choose National Grid, they pay us for distribution and electricity costs. Where they choose to buy electricity from third parties, they pay us for distribution only and pay the third-party supplier for the electricity. Our base charges for electricity supply are calculated to recover the purchased power costs.

		What we do – Gas
		The gas industry connects producers, processors, storage, transmission and distribution network operators, as well as suppliers to industrial, commercial and domestic users.


		System operator As system operator we are responsible for the high pressure gas National Transmission System (NTS) in Great Britain. We have responsibility for the residual balancing activities on the NTS and for keeping the physical system within safe operating limits. Our price control, set by Ofgem, includes incentives that aim to maintain and improve our daily operational efficiency and are subject to renegotiation at set intervals.				We are the sole owner and operator of gas transmission infrastructure in Great Britain. In the US, we hold a minority interest in two interstate pipelines: Millennium Pipeline Company and Iroquois Gas Transmission System. Interstate pipelines are regulated by the Federal Energy Regulatory Commission (FERC). In the UK, gas leaves the transmission system and enters the distribution networks at high pressure. It is then transported through a number of reducing pressure tiers until it is finally delivered to consumers. There are eight regional gas distribution networks in the UK, four of which are owned by National Grid. In the US, gas is delivered by the interstate pipeline companies to local distribution networks. Each local distribution company has a geographically defined service territory and is the only local distribution company within that territory. Local distribution companies are regulated by the relevant local state’s utility commission. Our networks deliver gas to 10.9 million consumers in the UK and 3.6 million customers in the US. Pipeline shippers bring gas from producers to suppliers, who in turn sell it to customers. We do not supply gas in the UK. However, we own National Grid Metering, which provides meters and metering services to supply companies, under contract. In the UK, customers pay the supplier for the cost of gas and for its transportation. We transport the gas through our network on behalf of shippers, who pay us transportation charges. In the US, gas distribution companies, including National Grid, sell gas to consumers connected to their distribution systems. In most cases in the US, where customers choose National Grid, they pay us for distribution and gas costs. Where they choose to buy gas from third parties, they pay us for distribution only and pay the third-party supplier for the gas and upstream transportation capacity. Also in the US, except for residential consumers in Rhode Island, customers may purchase their supply from independent providers with the option of billing for those purchases to be provided by us.
		Gas used in the UK is mainly sourced from gas fields in the North and Irish seas, piped from Europe and imported as LNG. There are seven gas reception terminals, three LNG importation terminals and three interconnectors connecting Great Britain via undersea pipes with Ireland, Belgium and the Netherlands. Importers bring LNG from the Middle East, the Americas and other places. Gas used in the US is produced mainly in North America. We import LNG from a number of countries. We do not produce gas in either the UK or US. In the UK, we own and operate Grain LNG, an importation terminal and storage facility at the Isle of Grain in Kent, which charges customers under long-term contracts for various services. These include access to our importation terminal, storage facilities and capacity rights. In the US, we own and operate LNG storage and vaporisation facilities, as well as an LNG storage facility in Providence, Rhode Island, where we store gas for third parties for a fee. We also buy gas directly from producers and LNG importers for resale to our customers. The transmission systems generally include pipes, compressor stations and storage facilities, including LNG storage. They connect production through terminals to the distribution systems. In the UK, gas enters the transmission system through importation and reception terminals and interconnectors and may include gas previously held in storage. Compressor stations located along the network play a vital role in keeping large quantities of gas flowing through the system, particularly at times of high demand. The gas transmission system has to be kept constantly in balance, which is achieved by buying, selling and using stored gas. This means that, under normal circumstances, demand can be met.

Strategic Report

Our vision and strategy

Our vision describes our intentions and aspirations at the highest level. Our strategic objectives set out what we believe we need to achieve to deliver our vision and be recognised as a leader in the development and operation of safe, reliable and resilient energy infrastructure.

Strategic objective

Description

How we deliver

Deliver
operational
excellence

LOGO

Achieve world-class levels of safety, reliability, security and customer service.

Our customers, communities and other stakeholders demand safe, reliable and secure supply of their energy. This is reflected in our regulatory contracts where we are measured and rewarded on the basis of meeting our commitments to customers and other stakeholders.

Pursuing excellence in all our operational processes will allow us to manage our assets efficiently, deliver network improvements quickly and provide services that meet the changing demands of our customers.

Engage
our people

LOGO

Create an inclusive, high-performance culture by developing all our employees.

It is through the hard work of our employees that we will achieve our vision, respond to the needs of our stakeholders and create a competitive advantage. Encouraging engaged and talented teams that are in step with our strategic objectives is vital to our success.

Our presence within the communities we serve, the people we work with and our opportunities to grow both individually and as a business are all important to making National Grid a great place to work.

Stimulate
innovation

LOGO

Promote new ideas to work more efficiently and effectively.

Our commitment to innovation allows us to run our networks more efficiently and effectively and achieve our regulatory incentives. Across our business, we explore new ways of thinking and working to benefit every aspect of what we do.

Embedding innovation and new technology into our operations helps us deliver continuous improvements in the quality and cost of our services.

Engage
externally

LOGO

Work with external stakeholders to shape UK, EU and US energy policy.

Policy decisions by regulators, governments and others directly affect our business. We engage widely in the energy policy debate, so our position and perspective can influence future policy direction. We also engage with our regulators to help them provide the right mechanisms so we can deliver infrastructure that meets the changing needs of our stakeholders.

Embed
sustainability

LOGO

Integrate sustainability into our decision making to create value, preserve natural resources and respect the interests of our communities.

Our long-term sustainability strategy sets our ambition to deliver these aims and to embed a culture of sustainability within our organisation.

That culture will allow us to make decisions that protect and preserve natural resources and benefit the communities in which we operate. We remain committed to our targets of a 45% reduction in Scope 1 and 2 greenhouse gas emissions by 2020 and 80% by 2050.

Drive growth

LOGO

Grow our core businesses and develop future new business options.

We continue to maximise value from our existing portfolio, while exploring and evaluating opportunities for growth. Making sure our portfolio of businesses maintains the appropriate mix of growth and cash generation is necessary to meet the expectations of our shareholders.

We review investment opportunities carefully and will only invest where we can reasonably expect to earn acceptable returns.

Combining this disciplined approach with operational and procurement efficiencies gives us the best possible opportunity to drive strong returns and meet our commitments to investors.

Customer and community value

Safety and reliability – we strive to provide reliable networks safely, which is essential to safeguard our customers, employees and the communities in which we operate.

Affordability – we strive to provide services efficiently, which helps to reduce the amount of money consumers have to pay for their energy.

Customer service – providing essential services that meet the needs of our customers and communities is a crucial part of the value they expect from us.

Sustainability – we strive to protect the environment and preserve resources for current and future generations.

Emergency services – we provide telephone call centres, coordinate the response to gas emergencies, and respond to severe weather events.

Community engagement – we listen to the communities we serve and work hard to address concerns about the development of our networks. Our employees volunteer for community-based projects and we support educational initiatives in schools.

Shareholder value

Regulatory frameworks – operating within sound regulatory frameworks provides stability. Making sure these frameworks maintain a balance between risk and return underpins our investment proposition.

Reputation – our approach to safety and our reliability record underpin our reputation. These are crucial factors that contribute towards positive regulatory discussions and help us pursue new business opportunities.

Efficient operations – efficient capital and operational expenditure allows us to deliver network services at a lower cost and reduces working capital requirements.

Maximising incentives – if we perform well against our incentives, and deliver the outputs our customers and regulatory stakeholders require, we can make the most of our allowed returns.

Funding and cash flow management – securing low-cost funding and carefully managing our cash flows help us maintain strong returns for our investors.

Disciplined investment – we can increase our revenue and earnings by investing in both regulated and non-regulated assets. This helps us deliver attractive returns for our shareholders.

Delivering our strategy – key performance indicators

The Board uses a range of financial and non-financial metrics, reported periodically, against which we measure Group performance.


		KPI and definition						Our performance
		Adjusted EPS Adjusted earnings represent profit for the year attributable to equity shareholders. This excludes exceptional items, remeasurements and stranded cost recoveries (see pages 103 and 104). Adjusted earnings per share provides a measure of shareholder return that is comparable over time.						Adjusted EPS pence¹ 1. Comparative amounts have been restated to reflect the impact of additional shares issued as scrip dividends.

We are adding new KPIs to better reflect the issues that matter most to our Company and our stakeholders. For this 2014/15 Report, we have included information about workforce diversity, as set out on pages 18 and 19. We aim to include two further new KPIs in our 2015/16 Report. These relate to community engagement and investment in education, skills and capabilities. Executive remuneration is linked to some of our KPIs.


Commentary		Target
For the year ended 31 March 2015, adjusted earnings attributable to equity shareholders increased by £174 million to £2,189 million. This increase in earnings resulted in an adjusted earnings per share of 58.1 pence, an increase of 9% on 2013/14. The earnings increase was driven by a £199 million increase in adjusted operating profit. With the exception of our UK Gas Distribution business, we saw increases in adjusted operating profit across all of our business segments.	Overall adjusted net finance costs reduced by £75 million across the Group which was broadly offset by a higher adjusted tax charge of £114 million reflecting the increase in profits across the Group. See page 20	The adjusted EPS target set as part of executive remuneration for APP was more than met with 100% of maximum achieved (see page 70).
Group RoE has increased during the year to 11.8%, from 11.4% in 2013/14. The UK regulated businesses delivered good returns of 13.7% in aggregate in the second year of their new price controls, including the assumed 3% long run average RPI inflation.	US returns of 8.4% were slightly down on last year, reflecting the additional costs incurred on gas leak repair and compliance and the increased level of rate base growth since 2013. See page 21	The Group RoE target set as part of executive remuneration for APP was more than met with 100% of maximum achieved (see page 70).
Our regulated assets have increased by 7% (£2.3 billion) to £37.0 billion. This reflects the continued high levels of investment in our networks in both the UK and US, together with the impact of the stronger US dollar. The rate of growth at constant currency was 3%.	The UK regulatory asset value (RAV) increased by £0.5 billion, reflecting significant capital expenditure, together with inflation, although at 0.9% RPI, this has had a smaller impact than in recent years. US rate base has increased by £1.8 billion this year. Of this, £1.2 billion was due to foreign exchange movements increasing the rate base reported in sterling. Excluding foreign exchange, rate base increased by £0.6 billion, reflecting a record year of US investment. See page 21	No specific target. Our overall aim is to increase regulated asset growth above the underlying rate of inflation.
Value added in the year was lower than 2013/14, primarily due to the impact of lower RPI on UK regulated asset growth. RPI inflation for March 2015 was 0.9% compared with 2.5% in March 2014 and National Grid’s long run assumption of 3%.	Of the £1.7 billion value added in 2014/15, £1,271 million was paid to shareholders as cash dividends and £335 million as share repurchases (offsetting the scrip issuance during the year), with £79 million retained in the business. See page 21	No specific target. Our overall aim is to sustainably grow value added over the long term while maintaining performance of our other financial KPIs.
In the UK we maintained a world-class employee safety performance during 2014/15, with an employee injury frequency rate of 0.09. Our US business improved its safety performance, with an employee injury frequency rate of 0.15.	Overall, our Company-wide injury frequency rate of 0.13 is better than last year and means that we bettered our target of 0.15. However, we did not meet our ambition to reach a world-class level by 2015. See UK Principal operations: pages 27–31 and US Principal operations: pages 33–35	We achieved our Company-wide employee IFR target of 0.15.

Commentary		Target
We aim to deliver reliability by: planning our capital investments to meet challenging demand and supply patterns; designing and building robust networks; risk-based maintenance and replacement programmes; and detailed and tested incident response plans. In the UK, our networks performed well. Despite tighter winter margins than previous years, we were able to operate the system without calling upon our additional reserve.	In the US, despite low temperatures and record levels of snowfall in parts of New England our network resilience held up well. We invested millions of dollars in both our electricity and gas infrastructure to improve resilience and help reduce the impact of service interruptions. See UK Principal operations: pages 27–31 and US Principal operations: pages 32–35	We achieved our targets, which are set out in the table for our UK networks, and are set individually for each of our US jurisdictions.
Our customer satisfaction KPI comprises seven components: Ofgem’s UK electricity transmission, gas transmission and gas distribution customer satisfaction scores; and four J.D. Power and Associates customer satisfaction surveys in the US. We have exceeded the two UK electricity and gas transmission targets; the outcome for the third UK KPI component will be published later this year (see note opposite).	In the US, we did not achieve our targets. Customers were concerned about higher-than-normal winter bills as a result of electricity commodity price increases and higher gas usage due to cold weather. In an effort to rebuild trust and customer satisfaction, we put in place a customer outreach and education programme that focused on energy saving solutions and bill management. See UK Principal operations: pages 27–31 and US Principal operations: pages 32–35	Our targets for each business area are set out in the table. We achieved our UK transmission targets, but did not achieve our US targets.
We measure employee engagement through our employee opinion survey. The results of our 2015 survey, which was completed by 83% of our employees, have helped us identify specific areas where we are performing well and those areas we need to improve. Our engagement index has risen by four points to 75%, our highest engagement score since we started conducting Group-wide employee opinion surveys. Managers receive a scorecard that aims to	create greater leadership accountability and we produce survey reports and action plans at Company, regional, business unit, function and team levels. See Our people: pages 24–25	We achieved our target of increasing engagement compared with the previous year.
Our Scope 1 and 2 greenhouse gas emissions (excluding electricity transmission and distribution line losses) for 2014/15 equate to 7.3 million tonnes carbon dioxide equivalent; a 63% reduction against our 1990 baseline. These emissions are equivalent to an intensity of around 478 tonnes per £million of revenue. We measure and report our greenhouse gas emissions in accordance with the World Resources Institute and World Business Council on Sustainable Development	Greenhouse Gas Protocol: Corporate Accounting and Reporting Standard (Revised Edition) for all six Kyoto gases, using the operational approach for emissions accounting. Those Scope 1 and 2 emissions are independently assured against the international standard ISO 14064-3 Greenhouse Gas assurance protocol. A copy of this statement of assurance is available on our website.	Our target, described on the facing page, is in progress.
During 2014/15, the percentage of both women and ethnic minorities in our workforce increased slightly. For more details about the breakdown by gender at different levels of the organisation, as well as information relating to subsidiary directors, see page 25. During 2014/15 we were recognised as a Times Top 50 Employer for Women for 2015 and reached the Gold level in our benchmarking with both Race for	Opportunity and Opportunity Now. In the UK and US, our Employee Resource Groups continue to support our business goals and inclusion and diversity initiatives. See Our people: pages 24–25	No specific target set. We aim to develop and operate a business that has an inclusive and diverse culture.

		We have delivered another year of strong financial performance in the UK and solid performance in the US with record investment levels.


Additional commentary on financial KPIs Adjusted operating profit Adjusted operating profit for the year ended 31 March 2015 was £3,863 million, up £199 million (5%) from last year. With the exception of our UK Gas Distribution business, we saw increases in operating profit in all of our business segments. Adjusted operating profit by segment £m For the year ended 31 March 2015, adjusted operating profit in the UK Electricity Transmission segment increased by £150 million. Net regulated income after pass-through costs was £230 million higher, principally reflecting increases in allowed transmission owner revenues this year and a £43 million benefit relating to legal settlements. This was partially offset by under-recoveries of allowed revenue in the year of £89 million compared with under-recoveries of £60 million in the prior year. Regulated controllable costs were £14 million higher due to inflation, organisational change costs and additional tower maintenance costs. Depreciation and amortisation was £33 million higher reflecting the continued capital investment programme, and other costs were £4 million higher than prior year. UK Gas Transmission adjusted operating profit increased by £20 million to £437 million. Net regulated income after pass-through costs was £42 million higher due to earned gas permit and constraint management incentives. In addition, under-recoveries of allowed revenue in the year of £18 million were £3 million favourable to last year’s under-recoveries of £21 million. Partially offsetting the revenue gains, regulated controllable costs were £8 million higher, including additional system operator costs relating to EU work. Other operating costs were also £17 million higher, including decommissioning costs of the Avonmouth LNG plant. UK Gas Distribution adjusted operating profit decreased to £826 million from £904 million in 2013/14. Net regulated income after pass-through costs was £11 million lower, reflecting changes in allowed revenues for repex expenditure. Timing differences reduced net revenues by a further £16 million, with £13 million over-recoveries in 2014/15 compared with a £29 million over-recovery in the prior year. Regulated controllable costs were £22 million higher primarily due to inflation and organisational change costs. Depreciation and amortisation was £15 million higher reflecting the continued capital investment programme, and other costs were £14 million higher than prior year, including provision for additional asset protection costs.				Within our US Regulated businesses, adjusted operating profit increased by £39 million to £1,164 million. The stronger dollar increased operating profit in the year by £30 million. Excluding the impact of foreign exchange, net regulated income increased by £81 million, reflecting increased revenue allowances under the Niagara Mohawk three year rate plan and other regulated revenue increases, partially offset by the impact of the end of LIPA management services agreement (MSA) in December 2013. In addition, over-recoveries of allowed revenues in the year of £30 million were £20 million favourable to last year’s over-recoveries of £10 million. Regulated controllable costs increased by £17 million excluding the impact of foreign exchange, as a result of increased gas leak and compliance work and additional costs incurred to improve data quality to bring regulatory filings up to date. This was partly offset by the removal of costs associated with the LIPA MSA activities. Following last year’s exceptionally cold winter, bad debt costs were £62 million higher excluding the impact of foreign exchange. There were no major storms affecting our operations in the years ended 31 March 2014 and 2015. Adjusted operating profit in Other activities was £68 million higher at £199 million. Operating profit in the French interconnector was £18 million higher as a result of strong auction revenues this year. In the US, corporate and other activities losses were £63 million lower, mainly as a result of the completion of the enterprise resource planning system stabilisation in the first half of the year. Adjusted earnings For the year ended 31 March 2015, adjusted net finance costs were £75 million lower than 2013/14 at £1,033 million, mainly as a result of lower average gross debt through the year, lower RPI rates in the UK and refinancing debt at lower rates. The adjusted tax charge was £114 million higher than 2013/14. This was mainly due to higher profits before tax and the non-recurrence of one-off items that benefited the prior year. As a result of this, the effective tax rate for 2014/15 was 24.2% (2013/14: 22.5%). The earnings performance described above has translated into adjusted earnings of £2,189 million, up £174 million on last year. This equates to adjusted earnings per share (EPS) of 58.1 pence, up 4.6 pence (9%) on 2013/14. Scrip restatement In accordance with IAS 33, all EPS and adjusted EPS amounts for comparative periods have been restated as a result of shares issued via scrip dividends. Measurement of financial performance We describe and explain our results principally on an adjusted basis and explain the rationale for this on page 186. We present results on an adjusted basis before exceptional items, remeasurements and stranded cost recoveries. See page 186 for further details and reconciliations from the adjusted profit measures to IFRS, under which we report our financial results and position.

This section provides additional commentary on our KPIs and other performance metrics we use to monitor our business performance. Analysis of our financial performance and position as at 31 March 2015, including detailed commentary on the performance of our operating segments, is located in the financial statements. However, this analysis still forms part of our Strategic Report financial review. See page 77 for further information. See pages 187 to 189 for commentary on our financial performance and position for the year ended 31 March 2014 compared with 31 March 2013. We have also included analysis of our UK regulated financial performance by segment on page 100.

A reconciliation between reported operating profit and adjusted operating profit is provided below. Further commentary on movements in the income statement is provided on page 87.

US rate base has increased by £1.8 billion this year. Of this, £1.2 billion was due to foreign exchange movements increasing the rate base reported in sterling. Excluding foreign exchange, rate base increased by £0.6 billion, reflecting a record year of US investment.

Value added

Our dividend is an important part of returns to shareholders along with growth in the value of the asset base attributable to equity investors. These are reflected in the value added metric that underpins our approach to sustainable decision-making and long-term incentive arrangements.

Overall value added in the year was £1.7 billion or 44.7 pence per share as set out below:

We measure our performance in generating value for our shareholders by dividing our annual return by our equity base.

Group RoE has increased during the year to 11.8%, from 11.4% in 2013/14. During the year, the UK regulated businesses delivered good returns of 13.7% in aggregate in the second year of their new price controls (2013/14: 12.7%), including the assumed 3% long-run average RPI inflation. US returns (on a higher average equity ratio than the UK) of 8.4% were down on last year, reflecting the additional costs incurred on gas mains repair and emergency leak response and the increased level of rate base growth since 2013. Overall, other activities in the Group delivered a good performance, including an improved result from the French interconnector and lower US corporate costs following the completion of the enterprise resource planning system stabilisation during the year. Treasury performance also helped the result, partly assisted by lower RPI accretions on the Group’s index-linked debt. Together, these helped to offset the headwind from lower cost of debt allowances under the tracker within the new UK price controls.

Regulated asset growth

In total our UK regulated asset value (RAV) and US rate base increased by £2.3 billion (7%) to £37.0 billion. This reflects the continued high levels of investment in our networks in both the UK and US, together with the impact of the stronger US dollar. The rate of growth at constant currency was 3%.

The UK RAV increased by £0.5 billion, reflecting significant capital expenditure, together with inflation, although at 0.9% RPI, this has had a smaller impact than in recent years. UK RAV growth also included capitalised efficiencies or ‘performance RAV’ of £111 million this year.

Value added in the year was lower than 2013/14 (£2.1 billion or 57.2 pence per share), primarily led by the impact of lower RPI on UK regulated asset growth. RPI inflation for March 2015 was 0.9% compared with 2.5% in March 2014 and National Grid’s long-run assumption of 3.0%. Of the £1.7 billion value added in 2014/15, £1,271 million was paid to shareholders as cash dividends and £335 million (excluding £3 million of transaction costs) as share repurchases (offsetting the scrip issuance during the year), with £79 million retained in the business.

The Board is confident that growth in assets, earnings and cash flows, supported by improving cash efficiency and an exposure to attractive regulatory markets, should help the Group to maintain strong, stable credit ratings and a consistent prudent level of gearing, while delivering attractive returns for shareholders.

Other performance measures

UK regulated return on equity

The UK RoE has increased 100bps to 13.7%, reflecting particularly strong incentive performance in the Gas Transmission business and further outperformance against our totex targets in Electricity Transmission, achieved through efficiencies within the capital investment programme. This performance represents 360bps outperformance over allowed returns. Our UK RoE does not include the impact of legal settlement benefits of £56 million. If these were included UK RoE would increase by 60bps to 14.3%.

UK return on equity % US regulated return on equity The US RoE has decreased 60bps to 8.4%, reflecting the additional costs incurred this year as a result of the severe winter weather and the additional gas mains leak investigation and repair work required, together with rate base growth. US return on equity¹ % 1. Calculated on a calendar year basis. Cash generated from operations Cash generated from operations was £5,350 million (2013/14: £4,419 million). Changes in working capital improved by £360 million over the prior year, principally in the US (£441 million) due to the collection of high winter 2014 billings and other settlements including Superstorm Sandy reinsurance claims and LIPA receipts. Cash outflows relating to exceptional items were £133 million lower, as the prior year included reorganisation costs in the UK and LIPA MSA transition costs in the US. Net debt and credit metrics Our net debt levels will continue to grow for the next few years as we fund our capital investment programmes and enhance our networks. We continue to borrow at attractive rates when needed and the level of net debt remains appropriate for our business. During 2014/15, net debt has increased by £2.7 billion. This is predominantly due to movements in foreign exchange rates as the US dollar strengthened against sterling. Gross borrowings are relatively consistent year on year, reflecting the current year net refinancing of maturities and bond repurchases, while cash and investment levels have been actively managed down. With the commencement of the RIIO price controls in 2013 and the slow down in our planned near-term UK capital investment programme as the industry assesses the impact of Electricity Market Reform, we reviewed and restructured the Group debt portfolio. The review resulted in a £924 million bond repurchase programme, of which £295 million was achieved through a cash tender offer for five bonds. The net repurchase cost of £131 million has been presented as exceptional finance costs in the income statement, as noted on page 104.				A key measure we use to monitor financial discipline is retained cash flow divided by adjusted net debt (RCF/net debt). This is a measure of the operating cash flows we generate, before capital investment but after dividends paid to shareholders, compared with the level of debt we hold. The principal adjustment made to net debt is to include pension deficits. RCF/net debt was 11.2% for the year (2013/14: 10.5%; 2012/13: 11.4%). For the current year we have used this measure to actively manage scrip uptake through buying back shares when supported by sufficient headroom. Deducting the cost of buying back these shares reduces RCF/net debt to 9.9% for the year. Our long-term target range for RCF/net debt is to exceed 9.0%, which is consistent with the A3 rating threshold used by Moody’s, the rating agency.








				We additionally monitor interest cover, which is a measure of the cash flows we generate compared with the net interest cost of servicing our borrowings. Interest cover for the year was 5.1 times (2013/14: 4.1 times; 2012/13: 3.9 times). Our target long-term rate for interest cover is in excess of 3 times. Return on capital employed RoCE provides a performance comparison between our regulated UK and US businesses and is one of the measures that we use to monitor our portfolio of businesses. The table below shows our RoCE for our businesses over the last five years: Return on capital employed % The UK RoCE has increased from 8.0% to 8.6% in 2014/15. This reflects the strong incentive performance in Gas Transmission and further totex outperformance in Electricity Transmission, together with one-off benefits of legal settlements in the year. US RoCE has decreased by 40bps in the year to 6.0%, as a result of the additional maintenance to improve reliability and safety and bring regulatory filings up to date, together with rate base growth driven by capital expenditure spend. Capital expenditure For the year ended 31 March 2015, capital expenditure of £3,470 million was at a similar level to last year, with reductions in spend in UK Electricity Transmission being offset by increases in capital spend in our US Regulated businesses. The reduction in spend in UK Electricity Transmission reflected delays in the manufacture of cable for the Western HVDC link and a reduced level of overhead line work, with a number of projects having completed over the last two years. In addition

we continue to look for innovative ways to reduce total expenditure (totex) under our RIIO regulatory arrangements while still delivering agreed outputs.

Within our US Regulated businesses, capital expenditure was higher year on year reflecting higher levels of mains replacement work, gas system reinforcement and growth spend, electricity capacity spend and progress on the New England East-West Solution (NEEWS) electricity transmission project.

Dividend growth

We remain committed to our dividend policy to grow the dividend at least in line with the rate of average RPI inflation each year for the foreseeable future.

During the year we generated £2.1 billion of business net cash flow after our capital expenditure programmes. This has enabled the growth of the dividend in line with average RPI, being 2.0% (2013/14: 2.9%; 2012/13: 4.0%), taking into account the recommended final dividend of 28.16 pence.

During the year, the Company has repurchased shares in the market with the overall goal being to reduce the dilutive effect of the scrip as much as possible to the extent that is consistent with maintaining the Group’s strong financial position as reflected in its credit rating.

Regulatory financial performance

Timing and regulated revenue adjustments

As described on pages 166 to 172, our allowed revenues are set in accordance with our regulatory price controls or rate plans. We calculate the tariffs we charge our customers based on the estimated volume of energy we expect will be delivered during the coming period. The actual volumes delivered will differ from this estimate. Therefore, our total actual revenue will be different from our total allowed revenue. These differences are commonly referred to as timing differences.

If we collect more than the allowed level of revenue, the balance must be returned to customers in subsequent periods, and if we collect less than the allowed level of revenue we may recover the balance from customers in subsequent periods. In the US, a substantial portion of our costs are pass-through costs (including commodity and energy efficiency costs) and are fully recoverable from our customers. Timing differences between costs of this type being incurred and their recovery through revenue are also included in timing.

The amounts calculated as timing differences are estimates and subject to change until the variables that determine allowed revenue are final.

Our operating profit for the year includes a total estimated in-year under-collection of £64 million (2013/14: £42 million under-collection). Our closing balance at 31 March 2015 was £27 million under-recovered.

In the UK, there was a cumulative under-recovery of £177 million at 31 March 2015 (2014: under-recovery of £83 million). All other things being equal, the balance will start to be recovered from customers in the year ending 31 March 2016.

In the US, cumulative timing over-recoveries at 31 March 2015 were £150 million (2014: £117 million over-recovery). The majority of that balance will be returned to customers next year.

In addition to the timing adjustments described above, as part of the RIIO price controls in the UK, outperformance against allowances as a result of the totex incentive mechanism, together with changes in output-related allowances included in the original price control, will almost always be adjusted in future revenue recoveries, typically starting in two years’ time.

Our current IFRS revenues and earnings include these amounts that will need to be repaid or recovered in future periods. Such adjustments will form an important part of the continuing difference between reported IFRS results and underlying economic performance based on our regulatory obligations.

For our UK regulated businesses as a whole, regulated revenue adjustments totalled £174 million in the year (2013/14: £106 million). This is based on our estimates of: work carried out in line with allowances; in expectation of future allowances; or work avoided altogether – either as a result of us finding innovative solutions or of the need being permanently removed.

In the US, accumulated regulatory entitlements to future revenue net of over- or under-recoveries amounted to £1,528 million at 31 March 2015 (2014: £1,024 million). These entitlements cover a range of different areas, with the most significant being environmental remediation and pension assets, as well as deferred storm costs.

All regulatory entitlements are recoverable (or repayable) over different periods, which are agreed with the regulators to match the expected payment profile for the liabilities. As at 31 March 2015, these extend until 2071.

Major storms

Despite the very cold winter across much of the US including record snowfall in parts of New England, there were no major storms in 2014/15 or 2013/14.

Safeguarding the future

There is a significant skills challenge facing the engineering profession in the UK. Research by EngineeringUK has highlighted a need for 1.8 million engineers, technicians and crafts people over the period 2012–2022. Around 60% of all new jobs in this period will need science, technology, engineering and maths (STEM) qualifications, yet not enough school children succeed in these areas.

There is a similar challenge in the US where the number of scientists and engineers needed to meet growth and net replacement needs between 2012 and 2022 is 2.3 million, including 1.2 million in the computer occupations and more than 540,000 engineers.

We are helping schools, parents and children see engineering as a modern, dynamic, desirable career with a great future. Our employees act as education ambassadors who volunteer their time for a range of activities in the classroom and at science and engineering fairs, most notably on STEM enrichment, careers education and work experience programmes.

Our careers education programmes in the UK include Careers Lab, an initiative we developed that was taken up by the charity Business in the Community in November 2014. It links working professionals from a range of sectors with schools to bring the world of work to life for secondary school children. A further initiative is the ‘Engineer Your Future’ exhibition at London’s Science Museum, which opened in December 2014 and explores engineering challenges through interactive games and digital experiences.

During 2014/15, we have expanded our residential work experience programme (balanced 50/50 between girls and boys) to include a non-residential programme for students aged 16–19 who are in sixth form or college and do not have an existing relationship with an employer.

This year, we invested nearly £900,000 in our education outreach, bringing benefits to 70 schools and more than 9,000 students who receive at least one hour of STEM/careers experience with our education ambassadors. We expect this to grow considerably in the UK through Careers Lab.

In the US, we continue to partner with seven local community colleges to deliver energy utility technology training programmes, designed to equip people for jobs in the energy industry. These programmes currently focus on future line workers. We plan to expand them to include technical skills for the gas industry.

We are continuing our partnership with the Center for Energy Workforce Development on its ‘energy industry fundamentals’, and we work with veterans through the US Troops to Energy Jobs programme. This is designed to help veterans make the transition from military service to the energy/utility industry.

We completed the fifth year of our Engineering Pipeline Program. This is a developmental programme designed to inspire promising students to become engineers and provide them an opportunity for fast tracked employment with National Grid.

We are working with the State University of New York and its network of colleges and universities. The aim is to prepare students for careers in the energy and utilities industry by improving the educational opportunities available to them. We expect this partnership to increase the volume of qualified entry-level candidates looking to join National Grid.

Our US work experience opportunities include six to eight week summer internships for college students, so they can gain work experience with National Grid. A number of these interns start their journey into the energy industry through our Engineering Our Future programme and go on to join our Company.

In the UK, we offer summer internships and also 12 month industrial placements to undergraduates in their penultimate year. These programmes offer students the opportunity to experience the culture, working and ethical practices of National Grid before they make the all-important decision to join the organisation as graduates.

Building skills and expertise

During 2014/15, we have worked on boosting the capabilities of our employees in the areas of Performance Excellence (see page 27), stakeholder engagement, customer focus and contract management. We see these capabilities as being crucial in helping us improve our performance and meet regulatory and customer expectations.

More than 900 employees have attended our Performance Excellence programmes; more than 650 employees have attended our stakeholder engagement and customer focus programmes; and around 250 employees have attended our contract management programmes.

Our executive team and senior leaders in the UK and US are participating in a programme to develop performance leadership skills. To prepare for our future engineering skills needs, we have built a T-pylon development facility at our Eakring learning centre in the UK.

We remain committed to investing in our people, providing the training and other support necessary for them to build, maintain and operate our networks safely and reliably, and this year we provided more than one million learner hours of training across our UK and US businesses.

Promoting an inclusive and diverse workforce We aim to develop and operate our business with an inclusive and diverse culture, with equal opportunity to all in recruitment, career development, training and reward. This applies to all employees regardless of race, gender identity, nationality, age, disability, sexual orientation, religion and background. Our policies support the attraction and retention of the best people, improve effectiveness, deliver superior performance and enhance our success. In the UK we were recognised as a Times Top 50 Employer for Women for 2015 and reached the Gold level in our benchmarking with both Race for Opportunity and Opportunity Now during 2014. Both these campaigns also recognised us as a Top 10 private sector employer. Our Employee Resource Groups (ERGs) continue to support our business goals and participate in events that encourage students to consider careers needing STEM qualifications. In the US, our ERGs support our business goals and ambitions. They are at the forefront of our inclusion and diversity initiatives – including our commitment to hire veterans and people with disabilities, as well as our efforts to promote understanding of unconscious bias. The table below shows the breakdown by gender at different levels of the organisation. We have included information relating to subsidiary directors, as this is required by the Companies Act 2006 (Strategic Report and Directors’ Reports) Regulations 2013. We define ‘senior management’ as those managers who are at the same level, or one level below our Executive Committee. It also includes those who are directors of subsidiaries, or who have responsibility for planning, directing or controlling the activities of the Company, or a strategically significant part of the Company, and are employees of the Company.							Health and wellbeing Among our programmes for 2014/15 we have worked to address the stigma and discrimination associated with mental health. We signed the UK Government-led ‘Time to Change’ pledge and have trained a further 92 employees in mental health first aid. We have also helped more than 4,000 of our employees and our service providers’ staff understand their ‘heart age’ and run a weight-loss campaign that raised more than £4,000 for Macmillan Cancer Support. In the US we have refreshed our soft tissue injury programme, aimed at helping reduce muscular skeletal disorders. Our employee opinion survey results continue to show that employees have a growing awareness of our wellbeing programmes. Volunteering Our employees continue to support our local communities, sharing their time and expertise on a range of skills-based volunteering and fundraising activities. In the UK we raised over £500,000 for good causes and provided over 9,000 hours of support to community projects. Our support of City Year now includes a new mentoring programme in Birmingham and we launched ‘Good Leaders’, a programme that shares our leadership expertise with the charity sector. In the US, our Power to Serve employee volunteering programme supports our stewardship and safety principles. It seeks to acknowledge existing community service, as well as to create new volunteer opportunities for employees. Human rights Respect for human rights is incorporated into our employment practices and our values. See page 185 for more information.

		Principal operations
		Overview of our UK operational businesses during 2014/15


		Our UK regulated businesses delivered a strong financial performance in the second year of RIIO. We aim to create value for our stakeholders by focusing on performance and making sure our processes are as efficient as they can be (see ‘Performance Excellence’ below). Savings generated in the first two years of RIIO will reduce future customer bills by around £200 million. We have also established a new organisational structure to give stakeholders a clearer picture of how our activities are organised and delivered. We have responded to concerns about the cost of energy and the security of the UK’s energy supply. In evidence to parliamentary inquiries we have explained our role, the services we provide and what those services cost. We have also been working with stakeholders in Europe to plan for the future impact of European Union energy policy on our business. Our non-regulated businesses have been focused on getting the best value from our existing portfolio and exploring opportunities for future growth. For further information see page 36. We have also signed two new interconnector agreements: with Elia, the Belgian Transmission System Operator, for an electricity interconnector between the UK and Belgium; and with Statnett, the Norwegian Transmission System Operator, for NSN Link, the first interconnector between the UK and Norway. These agreements signal the start of the construction phases of these projects. Principal risks As described in the Internal controls and risk management section (pages 38 to 41), we identify, monitor and manage risks at various levels within our Company. The key risks our UK business faces are organised into a UK regional risk profile which is regularly reviewed by UK senior leadership. The main risk themes currently featured in this profile are: ● the risk of changes to the complex political and regulatory agenda for UK and European energy policy development and their potential implications for our business; ● challenges associated with making sure the data required to deliver business processes and regulatory requirements is complete, accurate and consistent; ● the impact of changes in our business structure and processes on our ability to continue to perform under RIIO; and				● continued management of safety, security and network resilience. System Operator (SO) progress Our SO role is described on pages 08 and 11. The UK faces tightening capacity margins between supply and demand for the next three years. Helping the market to make the right decisions to maintain security of supply has been an important theme in our role as SO during 2014/15. Following a number of generation plant outages over the winter, the two new balancing services developed to provide additional reserves were tendered as a precaution. Although these additional reserves were not used this year, they have also been tendered to procure additional capacity for winter 2015/16 when margins are predicted to tighten further. We have continued to work with stakeholders to develop and implement EMR. We completed pre-qualification and auctions for the Capacity Market and the Contract for Difference (CfD) feed-in tariff regime. The capacity market auction this year procured additional capacity ready for the first year of delivery in 2018/19. Contracts were signed with 25 applicants following the first auction for CfD. We have led the development of changes to the gas transmission regulatory framework that will help customers plan their long-term projects through an improved way of reserving capacity. We have also developed a new framework that adds current system operation knowledge to long-term predictions about the future energy landscape. This helps us plan for the right services and products to operate the system in the future.
						Priorities for the year ahead Our role as SO is set to evolve during 2015/16, following the conclusion of Ofgem’s Integrated Transmission Planning and Regulation project. As part of this, the SO is expected to undertake a number of new advisory roles. We have a long track record in successfully managing potential conflicts of interest from our SO role and will work closely with Ofgem to make sure this continues. We will also be engaging further with the industry, aiming to increase opportunities for demand-side participation within the GB market.

		Performance Excellence Performance Excellence is an approach that will help us to achieve our Company objectives by looking for improvements to all of our processes. It aims to save time and make us more efficient so we can deliver better value for our customers and stakeholders – from new ideas that improve processes, to introducing equipment that does things more effectively. For example, in our UK Gas Distribution business, regional Performance Excellence teams are working with our operational teams to identify their common challenges and find the right solutions. As a result we have introduced a new helpdesk service for our Gas Distribution field force. This new service means technology problems are resolved more quickly, helping them to be more productive and better meet customer needs. See page 35 to read more about Performance Excellence in the US.

		UK Electricity Transmission


		What we do We own the electricity transmission system in England and Wales. Our networks comprise approximately 7,200 kilometres (4,470 miles) of overhead line, 1,500 kilometres (932 miles) of underground cable and 336 substations. Market context Although demand for electricity is generally increasing around the world, in the UK it is expected to remain broadly flat over the next five to 10 years.				Changes in the sources and characteristics of generation connecting to our network, such as wind and nuclear generation, mean we need to respond by developing the way we balance and operate our network to accommodate these sources. Over the last two years, some generators have delayed their connection dates to the network and this means our future investment profile for electricity transmission is flatter than in previous years. However, we are ready to respond to connection dates when we need to. We will continue to renew our network to deliver the network reliability our customers require as efficiently as possible.

		What we’ve achieved during 2014/15 The full tunnel network on our London Power Tunnels project has been completed, and the remaining works programme is forecast to complete ahead of schedule and under budget. We have also completed the development of a £164 million asset replacement and customer connection project for Wimbledon. We made progress on substation and cable construction work for several new Network Rail connections, as well as Crossrail connections in London. These connections are required to support the national railway electrification programme from 2015 to 2017. We achieved a significant engineering milestone, installing the first ever series compensation device on the UK network. This device, which adds capacity to a transmission circuit, can increase power flows from Scotland. With both National Grid and Scottish Power series compensation in service, the Scotland-England boundary capacity is expected to increase by 1 GW. We have continued to develop the innovative T-pylon and are considering where it could be offered alongside other connection options when developing new transmission circuits. The first T-pylon has been installed at our Eakring training facility.				Our Visual Impact Provision (VIP) project gathered pace. Our policy to make use of the £500 million allowance under RIIO to mitigate the visual impact of our overhead lines in National Parks and Areas of Outstanding Natural Beauty was agreed with Ofgem. A stakeholder advisory group, including representatives of organisations with a national focus on our natural heritage, is helping us choose which transmission lines should be prioritised and how the fund should be allocated. We agreed an RPI-linked bank loan facility of £1.5 billion with the European Investment Bank (EIB). This is the largest ever single loan by the EIB and is now available to fund capital investment in National Grid Electricity Transmission plc. We also deployed new tools and systems to our field workforce, winning the Mobile Innovation category at the SAP UK Quality Awards.
						Priorities for the year ahead Safety: Make sure our suppliers and employees manage their safety performance when working near our transmission assets. This includes seeking evidence that they are using effective safety management systems. Maintenance: Establish a programme to change the way we plan and deliver all work on our assets by balancing risk, performance and delivery costs.
						Hinkley Point C connection: Continue to progress the regulatory submissions needed for the Hinkley Point C connection project to secure the funding for delivery. Visual Impact Provision: Through our VIP project we will identify the final locations where the visual impact of our networks will be reduced. Data and technology: Continue to improve how we define and capture the network data that helps us make better decisions on our assets and respond more quickly to customer demand for new connections.

		UK Gas Transmission


*In focus:*	What we do	the remainder coming from Norway, continental Europe, or further afield via shipped imports of LNG. Overall, supply capacity now exceeds peak demand by more than 25%, giving our customers significant flexibility over which sources of gas they choose to meet demand. Newer sources of supply, such as LNG importation terminals and storage sites, can respond to demand more quickly than traditional UKCS supplies. Our network therefore needs to be able to respond to changing day-to-day supply and demand patterns. We also need to prepare for an uncertain energy landscape in the long term. UK reliance on imported gas supplies will vary depending on the level of gas supply from the UKCS and the development of indigenous gas sources. We are working closely with our customers and stakeholders to meet these operational challenges. We are focused on continuing to develop our network and services to meet their needs safely, reliably and efficiently.

	a rise of 7% on the average for winter 2013/14. It follows targeted investment in our fleet of compressors and improvements to our planning process, maintenance and repair methods. We received £5.7 million from Ofgem following a successful bid in the Network Innovation Competition for designing and building a robotic device that can inspect below-ground pipework at high pressure installations. The device will help us to better assess asset condition, so we can focus expenditure where it is needed, benefiting gas consumers.	Priorities for the year ahead Safety: Sustain and improve our safety performance by implementing a new safety culture improvement programme across UK Gas Transmission. Reliability: Build on improvements we have made this year in compressor availability, extending this across other critical assets in our network to further improve the service we deliver to our customers. Efficiency: Continue improving end-to-end processes and deliver greater value for
		customers by being more efficient. Where we create additional capacity, we will look to insource some maintenance work and increase specialist pipeline services for customers. Innovation: Use the innovation opportunities available through the Network Innovation Competition and Network Innovation Allowance funding. This will help us to create value for customers and the industry, and to achieve our RIIO-T1 commitments. Emissions compliance projects: Continue work on existing emissions compliance projects and secure funding for continued works over the remainder of the RIIO-T1 period and beyond.

*In focus:*	What we do	Ofgem is able to make comparisons across all eight networks. It establishes outputs they are expected to deliver so that we all maintain a safe and reliable network; make a positive contribution to sustainability and protect the environment; provide connections to supply new consumers and support new gas entry points into the network; meet their social obligations; and provide an agreed standard of service to consumers and other stakeholders. We collaborate with the industry on issues that are common to all networks and customers, such as innovation, safety and the future of networks to deliver outcomes that customers value. Gas remains an important part of the current and future energy mix and we are working with our customers and stakeholders to develop our networks to accommodate gas from new sources, such as bio-methane.
Gas consumption in our networks was 260 TWh in 2014/15.	We own and operate four gas distribution networks comprising approximately 131,000 kilometres (82,000 miles) of pipeline. We transport gas from the national transmission system to around

This includes replacing approximately 1,450 kilometres of old metal pipelines with more durable materials as part of our mains replacement programme developed with the HSE and Ofgem. In London, we have replaced around 300 kilometres of iron mains, including projects in Battersea and around the City. We have also completed ten commercial bio-methane connections, more than any other UK gas distribution network, including the first 100% food waste plant and the first commercial sewerage connection with Severn Trent Water. Overall, we have delivered successfully against our targets to deliver world-class levels of safety performance across our combined field workers and contractor workforce. In terms of cable strikes and injuries to members of the public, although we have missed our targets, we have increased our efforts to make improvements. We have also used innovative technology that has helped reduce excavation volumes, so we can minimise disruption. We have also been helping stakeholders such as landowners and the construction industry understand how we protect pipelines and how they can operate safely around them. During 2014/15, we were recognised by Ofgem as the best performing gas distribution network in understanding our customer and stakeholder needs for the previous year. Our focus in this area has seen over 1,200 fuel poor customers benefiting from an alternative, more affordable method of heating their homes since we have connected them to our gas networks.	for customers who want to connect to our networks by improving our website experience and providing them with a single point of contact. We have invested in new mobile technology for our field workforce to increase productivity and provide our supervisors with real-time information. This has also helped improve employee engagement scores and the desire to drive better outcomes for our customers; our field workforce now compares favourably with industry benchmarks.
		Priorities for the year ahead Improve our safety performance by further reducing cable strikes, injuries to members of the public and preventing third-party encroachment. This will continue to be an important area of focus. Continue to use innovative technology to deliver better services that reduce the impact on customers’ bills and minimise disruption caused by our work. Improve our customers’ experience of planned replacement work projects by working with our partners to improve our processes, data capture and how we communicate and engage with our customers. Continue to work with government and industry on setting out the vision for the future role of gas in the UK’s energy mix and policies that support this role, while considering how domestic smart meters can create value for customers. Motivate and equip our workforce with the tools and knowledge they need to deliver the services and outcomes our customers value, while increasing productivity.

Principal risks

As described in the Internal controls and risk management section (pages 38 to 41), we identify, monitor and manage risks at various levels within our Company. The key risks our US business faces are organised into a US regional risk profile which is regularly reviewed by the US senior leadership. The main risk themes currently featured in this profile are:

● our ability to manage data integrity and

systems improvements required to

deliver core business processes and

regulatory requirements;

● our ability to recover costs through

existing rate-making mechanisms and to

influence the development of the future

US utility business model;

● our ability to enhance our US business

structure and end-to-end processes to

support an evolved jurisdictional

performance environment; and

● safety performance and network

reliability, security and resilience.

What we’ve achieved

During 2014/15, we delivered a solid performance and continued with high levels of investment in our networks. As described on pages 18 and 19, we achieved our reliability KPI targets but we still have work to do if we are to improve our customer satisfaction target scores.

We finally completed the stabilisation work on our new enterprise resource planning system. This fixed a number of long-standing problems, such as inefficient payroll processing, which had previously required expensive manual interventions. Long term, the data we can produce with the new systems are an essential foundation to the future performance improvements and regulatory filings that we need for profitable growth in the US.

In 2010, the Massachusetts Department of Public Utilities (MADPU) approved a power purchase agreement between National Grid and Cape Wind for a proposed large-scale, offshore wind farm in Nantucket Sound. In 2014, Cape Wind did not satisfy certain critical milestone deadlines set out in the power purchase agreement and did not post collateral to extend the deadlines in the power purchase agreement. As a result, the power purchase agreement was terminated in January of 2015. We continue to believe the solution to New England’s energy challenge is a diversity of energy sources, which is why we support renewable projects consistent with our goal of reducing emissions while minimising the cost impact on our customers.

In a joint programme with Earth Networks, we purchased 55 Weatherbug stations to donate to our communities in Massachusetts, New York and Rhode Island. These stations provide customers with more localised weather information and we use them to better prepare for and respond to storms. They also contribute to STEM education in giving free real-time local weather data to schools and emergency responders.

We continue to invest more in reinforcing the electricity distribution system and also in replacing

gas mains. The NYPSC approved $414 million gas infrastructure investment in Long Island to speed up the replacement of ageing pipe and extend the use of natural gas to more customers.

The NYPSC also published the results of the regulatory audit of our New York gas companies. These audits are a regular feature of the New York regulatory process. The audit was broadly supportive of our performance and structure and, as is usual, made some recommendations for further improvement. It specifically recommended stronger local leadership and a number of more cost-effective and customer-focused operational enhancements. We have responded with an implementation plan to provide these benefits on behalf of New York customers.

Last year, regulatory audits in New York also identified an unacceptable number of violations of the regulations relating to our gas operations. To improve our regulatory compliance performance, we are investing in compliance monitoring systems, adding compliance personnel, and enhancing our training and safety protocols.

Our regulators and customers have heightened expectations around safety and compliance for all gas utilities. We are committed to doing everything we can to meet their expectations and making sure sufficient resources are dedicated to support this priority.

Building on performance improvements in 2013/14, we saw a reduction in safety incidents in 2014/15. In the past year, there has been a 7% reduction in the number of injuries requiring medical attention and a 26% reduction in the number of cases requiring employees to stay out of work. These reductions result from programmes and initiatives based on risk areas, improved incident investigations and root cause analysis. There is still much work to do as we strive for zero injuries. Soft tissue injury prevention, safety observations, road traffic collisions and slips, trips and falls will remain a focus for us in 2015/16.

Each of our jurisdictions has projects under way to develop economic and environmental health in three ways: by driving economic growth; providing cleaner energy; and advancing innovative technologies. We have highlighted some of our 2014/15 achievements below.

Massachusetts

We are preparing to file a grid modernisation plan – a blueprint for the modernisation of the electric system – with MADPU in August 2015.

We have announced plans to build, own, and operate an additional 16 MW of solar generation, bringing total solar capabilities in the state to 21 MW.

As of late 2014, we had installed 39.9 miles of new gas mains and added more than 8,400 new natural gas customers.

New York

We are helping to shape new energy policy in the state through our REV filings. REV is aimed at transforming the electricity energy industry and regulatory practices in New York State.

We are adding new electricity capacity and infrastructure to RiverBend, Buffalo, a former industrial brownfield that is bringing growth and jobs to the state. Companies including Solar City and Soraa will bring investment, much needed jobs, and new and advanced energy technologies that could make this region a hub for energy development regionally, nationally and internationally.

We are negotiating a power purchase agreement with ReEnergy under which we intend to purchase excess energy from a 55 MW biomass generating facility at Fort Drum in Watertown. This will be the largest renewable energy project in the history of the US Army.

We have begun a two year plan to replace ageing pipes and expand the use of natural gas on Long Island and the Rockaway Peninsula to more than 20,000 new customers. This accelerates the replacement of ageing pipes from the current 50-mile requirement to 95 miles by 2016.

We are partnering with New York City to accelerate the phase out of heavy oils in around 800 buildings. Since the programme’s launch in 2011, we have converted over 500 heavy oil buildings. We continue our efforts to convert the few remaining clean heat eligible buildings on Staten Island.

Rhode Island

The $93 million Aquidneck Island Reliability Project, known as OnIsland, will bring more reliable power to the nearly 32,000 homes and businesses in Portsmouth, Middletown, and Newport. The project includes two substations, reconfiguration of two transmission lines, local distribution work, and retirement of five substations on the island.

We have been working with Toray Plastics, one of the largest employers in the state, on customised energy solutions. In 2014 the company opened its second cogeneration system at its 70-acre campus in North Kingstown and we supported them with an energy efficiency incentive of $15.9 million.

We are building a new state-of-the-art substation to replace the existing ageing infrastructure at the current South Street Substation, which powers downtown Providence. This coincides with a $206 million redevelopment of South Street Landing that will turn the vacant former South Street Power Station into teaching and administrative space for Brown University, Rhode Island College and the University of Rhode Island.

FERC

We are part of a joint venture to form New York Transco. This aims to construct, own, and operate incremental electric transmission assets in New York State to improve reliability and reduce congestion.

It is initially pursuing five projects that support public policy objectives and provide broad-based benefits across the state. New York Transco filed with FERC in December 2014 for rate recovery and cost allocation for proposed transmission projects, estimated at $1.7 billion.

We have joined Spectra Energy’s $3 billion proposed Access Northeast pipeline project that aims to significantly increase natural gas capacity to generators in New England. Our three New England electric distribution companies have established memoranda of understanding with project developers to explore the development of an innovative tariff that would enable them to take capacity from the pipeline and release it into the market as needed to mitigate wholesale electricity price spikes.

In December 2014, we announced we had joined forces with Anbaric Transmission to develop large-scale HVDC transmission projects to deliver a combination of domestic wind energy and Canadian hydropower to New England load centres. We are currently developing a 1,000 MW hybrid land and sea HVDC project from northern Maine to Greater Boston and a 400 MW underground HVDC project from upstate New York to Vermont under Lake Champlain.

We are working with Eversource Energy in implementing the Greater Boston and New Hampshire Solution to address critical grid reliability needs. We will be investing approximately $190 million in the Solution for new infrastructure in southern New Hampshire, northern Massachusetts, and the Greater Boston area. We expect the Solution to be in service by 2019.

Priorities for the year ahead

We continue our Connect21 journey with these four priorities for 2015/16: Performance Excellence; local operating model; talent and capabilities; and future energy networks.

Performance Excellence: We will improve the way we work as teams to become more efficient, innovative, and responsive to our customers’ needs in end-to-end processes that include: meter to cash; emergency response; deliver gas and electric; maintain gas and electric; and operate gas and electric.

Local operating model: We will continue to drive greater accountability and customer service by delivering the services and obligations expected by the 14 operating companies and four jurisdictions that comprise our US business – at a cost and performance level agreed upon by each jurisdiction’s management team.

Talent and capabilities: We will provide employees with the tools and resources they need to achieve the performance measures required by our customers and shareholders.

Future energy networks: We will update and create new electricity and gas networks through design, operational, and regulatory innovations.

Interconnectors The England-France interconnector (IFA) is a 2,000 MW HVDC link between the French and British transmission systems with ownership shared between National Grid and Réseau de Transport d’Electricité. The interconnector’s availability continued to improve this year following a significant valve replacement programme. Average availability for 2014/15 was 90.62%, up from 83.84% in 2013/14. A substantial proportion of the flow continues to be in the import direction, from France to Great Britain. BritNed is a joint venture between National Grid and TenneT, the Dutch transmission system operator. It owns and operates a 1,000 MW HVDC link between England and the Netherlands. As with IFA, a substantial proportion of the flow is in the import direction from the Netherlands to Great Britain. Throughout 2014/15, both IFA and BritNed have operated as part of the North West Europe market region. The creation of this region is part of the ongoing development of the EU’s Internal Energy Market. IFA and BritNed have entered this region voluntarily ahead of the introduction of new EU-wide rules for cross-border electricity trading.

Strategic Report

Internal control and risk management

The Board is committed to protecting and enhancing our reputation and assets,

while safeguarding the interests of our shareholders. It has overall responsibility

for the Company’s system of risk management and internal control.

National Grid is exposed to a variety of uncertainties that could have a material adverse effect on the Company’s financial condition, our operational results, our reputation, and the value and liquidity of our shares.

The Board oversees risk management, and, as part of this role, it reviews the main elements of our process and sets and monitors risk appetite. Risk appetite establishes the amount of uncertainty the Company may seek or accept at any given time when pursuing our strategic objectives.

The Board regularly reviews our internal controls and risk management processes. This year specific consideration was given to the guidance in the new UK Corporate Governance Code 2014 (the New Code) which applies to the Company in the next fiscal year and refinements to our processes will be introduced, as appropriate, over the coming year.

Risk management approach

Our Company-wide corporate risk management process provides a framework through which we can consistently identify, assess and prioritise, manage, monitor and report risks, as shown in the diagram below. The process is designed to support the delivery of our vision and strategy as described on pages 14 and 15.

Our process involves a continuous cycle of bottom-up review and reporting and top-down review and feedback.

All our business functions participate in the bottom-up risk management process. They identify the main risks to achieving their objectives and the actions being taken to manage and monitor them. They assess each risk by considering the potential ‘worst case credible’ financial and reputational impacts and how likely the risk is to materialise. The risks we identify are collated in risk registers and are reported at functional and regional levels of the Company. The risk registers also describe the adequacy of our existing risk controls.

An important feature of our risk management process is that each business function owns and is responsible for managing its particular risks. A central risk management team acts as an advisory function and also provides independent challenge and review. This team partners with the business functions through nominated risk liaisons and collaborates with assurance teams and specialists, such as internal audit and compliance management, to sense check risk information.

Regional senior management regularly review and debate the outputs of the bottom-up process and agree the prioritisation of the risks. The main risks for the UK and US businesses are highlighted in regional risk profiles and reported to the Chief Executive through quarterly performance reports. An overview of current risk themes for the UK and US businesses is provided on pages 27 and 34 respectively.

Our main strategic uncertainties or ‘principal risks’ for the Company are developed through top-down discussions with the Executive leadership team. These risks are reported and debated with the Executive Committee and Audit Committee every six months.

The Board participates in an annual risk workshop to make sure that the principal risks remain closely aligned to our strategic aims and that no important risks (or combination of risks) are being overlooked. In addition, the Board considers emerging risks (uncertainties that are still developing and sit outside the principal risks profile) together with our strategy team’s annual long-term update.

The outcomes from each level of the risk review process are fed back to the relevant teams and incorporated as appropriate into the next cycle of our ongoing process as shown below.

Risk management process

Our principal risks

Accepting that it is not possible to identify, anticipate or eliminate every risk that may arise and that risk is an inherent part of doing business, our risk management process aims to provide reasonable assurance that we understand, monitor and manage the main uncertainties that we face in delivering our objectives.

This includes consideration of inherent risks, which exist because of the nature of day-to-day operations in our industry, and financial risks, which exist because of our financing activities. An overview of the key inherent risks we face is provided on pages 173 to 176,

as well as an overview of our key financial risks, which is incorporated within the Notes to our consolidated financial statements on pages 94 to 158.

Our corporate risk profile contains the principal risks that the Board considers to be the main uncertainties currently faced by the Company as we endeavour to achieve our strategic objectives. An overview of these risks is provided below, together with examples of the relevant controls and current mitigating actions we are taking.

Strategic objective

Risk description

Example of mitigations

Drive growth

Failure to identify and execute the right opportunities to deliver our growth strategy.

Failure to sufficiently grow our core business and have viable options for new business over the longer term would negatively affect the Group’s credibility and jeopardise the achievement of intended financial returns.

Our ability to achieve our ambition for growth is subject to a wide range of external uncertainties, including the availability of potential investment targets and attractive financing and the impact of competition for onshore transmission in both the UK and US; and internal uncertainties, such as the performance of our operating businesses and our business planning model assumptions.

● We regularly monitor and analyse market conditions, competitors and their potential strategies, the advancement and proliferation of new energy technologies, as well as the performance of our Group portfolio. We are also looking to access new sources of finance and capabilities through partnering.

● We have internal processes for reviewing and approving investments in new businesses, disposals of existing ones and organic growth investment opportunities. These processes are reviewed regularly to make sure our approach supports our short- and long-term strategies. We undertake due diligence exercises on investment or partnering opportunities and carry out post-investment reviews to make sure we learn lessons for the future.

LOGO

Engage externally

Inability to influence future energy policy.

Policy decisions by regulators, governments and others directly affect our business. We must engage widely in the energy policy debate, making sure our position and perspective help to shape future policy direction.

● In the UK, we are continuing to work closely with DECC and Ofgem on Electricity Market Reform (EMR) plans. We successfully implemented the first Capacity Market Auction and Contracts for Difference Allocation process and are working with the Regulator to finalise the enduring EMR Business Plan to ensure we continue to deliver value under RIIO. We continue to maintain strong relationships with government, engage in consultations, and develop comprehensive stakeholder communication plans. The Board is also continuing to monitor the increasing public debate around the cost, availability, security and sustainability of UK energy supplies.

●

In the US, we are engaging our external stakeholders about the role of the utility company of the future, under the banner of Connect21. We believe this conversation will help shape the regulatory and fiscal regime in the US in the future. Regulatory proceedings related to utility of the future have been launched in New York (Reforming the Energy Vision) and Massachusetts (Grid Modernization) and our Connect21 aligns well with them. We are continuing to strengthen our jurisdictional focus and are improving our rate case filing capabilities so our businesses can continue to earn a fair and reasonable rate of return. Our rate filings include structural changes where appropriate, such as revenue decoupling mechanisms, capital trackers, commodity-related bad debt true-ups and pension and other post-employment benefit true-ups, as described on pages 169 and 172.

Engage our people

Inability to secure the business capacity, appropriate leadership capability and employee engagement levels required to deliver our vision and strategy.

It is through the high-quality work of our employees that we will achieve our vision, respond to the changing needs of our stakeholders and create a competitive advantage. Obtaining and fostering an engaged and talented team that has the knowledge, training, skills and experience to deliver on our strategic objectives is vital to our success. We must attract, integrate and retain the talent we need at all levels of the business.

● We have identified the core capabilities that align with our strategic ambition and defined our set of leadership standards.

● We have filled key leadership roles with a mix of internal and external hires.

● We are involved in a number of initiatives to help secure the future engineering talent required (see page 24).

● We continue to develop our succession plans for key roles, including leadership.

● We continue to actively promote inclusion and diversity.

● We monitor employee engagement and formally solicit employee opinions via a Company-wide employee survey annually.

LOGO

Deliver operational excellence

Failure to achieve levels of financial performance required to meet regulatory requirements.

The Group operates under a number of regulatory regimes and we must maintain the performance levels required. Failure to achieve the agreed returns could damage our reputation and threaten future growth opportunities and regulatory arrangements.

● We have a US strategy focused on safety and reliability, customer responsiveness, stewardship and cost competitiveness. Performance measures are tracked and reported monthly. US jurisdictional presidents continue to develop strong relationships with local regulators and communities. A Performance Excellence framework is firmly established to deliver sustainable and innovative performance improvements.

● The UK operating model implemented in 2013 to support our performance under RIIO is now established and we continue to roll out our Performance Excellence framework across the business. We actively engage with local communities and non-governmental actors.

● We monitor network reliability and customer satisfaction as KPIs, as described on pages 18 and 19.

Failure to deliver appropriate information systems and data integrity.

The Company is increasingly reliant on technology to support and maintain our business-critical processes. We must be able to rely on the performance of these systems and the underlying data to demonstrate the value of our business to our shareholders, and to meet our obligations under our regulatory agreements, and comply with agreements with bond holders and other providers of finance.

● We implemented a new US enterprise resource planning system at the end of 2012. After a significant effort to combat programme difficulties, the system is now stabilised and enhancements to drive business value are under way.

● We are undertaking a programme to strengthen identified weaknesses in US controls over financial reporting.

● We are implementing a global information management framework focusing on data integrity and security.

● We completed a data assurance programme last year and actions to improve our data quality and integrity processes based on the results are being managed by the business functions.

We experience a catastrophic/major cyber security breach.

Due to the nature of our business we recognise that our critical national infrastructure (CNI) systems may be a potential target for cyber threats. We must protect our business assets and infrastructure and be prepared for any malicious attack.

●

We use industry best practices as part of our cyber security policies, processes and technologies.

●

We continually invest in cyber strategies that are commensurate with the changing nature of the security landscape. This includes collaborative working with DECC and the Centre for Protection of National Infrastructure (CPNI) on key cyber risks and development of an enhanced CNI security strategy and our involvement in the US with developing the National Institute of Standards and Technology Cyberspace Security Framework.

LOGO

Failure to prevent a significant process safety event.

Safety is paramount. Some of the assets owned and operated by National Grid are inherently hazardous and process safety incidents, whilst extremely unlikely, can occur.

● We continue to commit significant resources and financial investment to maintain the integrity of our assets and we strive to continuously improve our key process safety controls.

● We continue to implement our Group-wide process safety management system to ensure a robust and consistent framework of risk management exists across our higher hazard asset portfolio.

Our objective is to be an industry leader in managing the process safety risks from our assets to protect our employees, contractors and the communities in which we operate. We operate in compliance with local legislation and regulation. In addition we identify and adopt good practices for safety management.

● We are developing a suite of risk models to assess the risk of specific asset types and support targeted investment to reduce risk.

● We monitor a mix of leading and lagging process safety indicators and test the effectiveness of our controls with periodic audits.



		Our internal control process We have a number of processes to support our internal control environment. These processes are managed by dedicated specialist teams, including risk management, ethics and compliance management, corporate audit and internal controls, and safety, environment and health. Oversight of these activities is provided through regular review and reporting to the appropriate Board committees as outlined in the Corporate Governance section on pages 42 to 59. Reviewing the effectiveness of our internal control and risk management Each year the Board reviews the effectiveness of our internal control systems and risk management process covering all material systems, including financial, operational and compliance controls, to make sure they remain robust. The latest review covered the financial year to 31 March 2015 and the period to the approval of this Annual Report and Accounts. It included: ● the Certificate of Assurance for noting following consideration by the Audit Committee to provide overall assurance around the effectiveness of our risk management and internal controls systems; ● where appropriate, assurance from our committees, with particular reference to the reports received from the Audit, and Safety, Environment and Health Committees on reviews undertaken at their meetings; and ● assurances about the certifications required under Sarbanes-Oxley as a result of our US reporting obligations. The Board evaluated the effectiveness of management’s processes for monitoring and reviewing internal control and risk management, noting that no significant failings or weaknesses had been identified by the review and confirmed that it was satisfied the systems and processes were functioning effectively. Our internal control and risk management processes comply with the Turnbull guidance on internal control and the requirements of the UK Corporate Governance Code and the Financial Reporting				Council’s Guidance on Risk Management, Internal Control and Related Financial and Business Reporting. They are also the basis of our compliance with obligations set by the Sarbanes-Oxley Act 2002 and other internal assurance activities. The New Code, published in September 2014, contained changes related to risk management. These changes have been reviewed against our risk management and internal control systems and processes. Refinements will be implemented, as appropriate, over the coming year. Internal control over financial reporting We have specific internal mechanisms to govern the financial reporting process and the preparation of the Annual Report and Accounts. Our financial controls guidance sets out the fundamentals of internal control over financial reporting, which are applied across the Company. Our financial processes include a range of system, transactional and management oversight controls. In addition, our businesses prepare detailed monthly management reports that include analysis of their results along with comparisons to relevant budgets, forecasts and prior year results. These are presented to and reviewed by senior management within our Finance function. These reviews are supplemented by quarterly performance reviews, attended by the Chief Executive and Finance Director which consider historical results and expected future performance and involve senior management from both operational and financial areas of the business. Each month the Finance Director presents a consolidated financial report to the Board. As part of our assessment of financial controls in the prior year, we identified a number of weaknesses in our US financial control framework. We are making progress in remediating these weaknesses. For more information, including our opinion on internal control over financial reporting, see page 173.

Dear Shareholders,

Our Board is responsible for shaping the culture, values and ethics of National Grid, both within the boardroom and across the organisation, by setting the tone from the top and establishing high standards of behaviour.

The changes introduced in 2014 to the UK Corporate Governance Code and the Financial Reporting Council guidance on risk management have highlighted the need for the Board to consider if the current risk management and internal control practices and culture of the Company support the spirit of the changes, not just the letter.

The updates to the New Code have been considered by the Board and refinements approved so we can report on compliance next year as required. It is the intention of the Board that any changes to the frequency and level of reporting received by the Board and Audit Committee in relation to risk management, compliance and internal control as a result of these updates, will also add value to the business.

A review of our compliance procedures is also underway to make sure that we continue to develop and improve our compliance with external reporting obligations. In order to further develop our internal assurance programme, we formed the Engineering Assurance Committee to promote the application of common, consistent, engineering assurance methodologies across the Company.

The Board received an in-depth presentation on security and cyber security which provided a framework for discussion around the threats we face and the effectiveness of our strategy to mitigate the inherent risks. We have made a significant investment over the last five years to improve our capabilities in this area so we can adapt to and address an ever-changing threat landscape. Following this session, we agreed that responsibility for making sure we have an effective process for managing cyber security risk should be delegated to the Audit Committee. You can read more about this on page 50. The Board will continue to receive an annual in-depth presentation on information systems and security, including cyber security.

This year, in addition to Nick Winser and Maria Richter stepping down at the 2014 AGM, we have said goodbye to Philip Aiken and Tom King and have welcomed John Pettigrew and Dean Seavers as Executive Directors in the UK and US respectively. In my role as Chairman and leader of the Board I am responsible for ensuring effectiveness in all aspects of its role. This includes promoting effective relationships and open communication between Directors and encouraging active engagement by all members. This is particularly important as the membership of the Board changes and new relationships are formed. I am pleased to report that the positive outcome of the Board and Committee evaluation process reflects this effectiveness. You can read more about this on page 46 and the rigorous selection process prior to Dean’s appointment on page 58.

Clear and concise communications with our shareholders remain a focus for the Board and we hope that the overview of our business model on page 12 helps to articulate how we create value for you, our shareholders, as well as our other stakeholders.

		Compliance statement The Board considers that it complied in full with the provisions of the UK Corporate Governance Code 2012 (the Code) during the financial year being reported, see page 53 for our explanation in relation to external audit tendering.
		This report explains the main features of the Company’s governance structure to give a greater understanding of how the main principles of the Code have been applied. The report also includes items required by the Disclosure and Transparency Rules. The index on page 59 sets out where to find each of the disclosures required in the Directors’ Report and in respect of Listing Rule 9.8.4, together with the Board’s sign-off on the report. UK Corporate Governance Code 2014 The new UK Corporate Governance Code 2014 (the New Code) applies to the Company for the next financial year, 2015/16. In March, the Board considered the current governance arrangements and approved refinements to support compliance with the New Code. Details will be provided in the 2015/16 Annual Report and Accounts. Fair, balanced and understandable The requirement for Directors to state that they consider the Annual Report and Accounts, taken as a whole, is fair, balanced and understandable remains a key consideration in the drafting and review process. The coordination and review of the Annual Report follows a well-established and documented process, which is conducted in parallel with the formal audit process undertaken by the external auditors and the review by the Board and its committees (of relevant sections). This process gives the Board comfort that all material statements are accurate and that the Annual Report gives sufficient prominence to negative as well as positive information. The drafting and assurance process supports the Audit Committee and Board’s assessment of the overall fairness, balance and clarity of the Annual Report and the Directors’ statement on page 78. Our Board Our current Board membership is set out on the previous page, with biographical details of Directors on pages 178 to 179. The Directors in place during the year are set out on page 49, together with details of Board meeting attendance. Committee membership during the year and attendance at meetings is set out in each of the individual committee reports later in this report. For further details about the Directors’ service contracts and letters of appointment, see page 67 of the Directors’ Remuneration Report. Role of our Board Our Board is collectively responsible for the effective oversight of the Company and its businesses. It also determines the strategic direction, business plan, objectives and governance structure that will help achieve the long-term success of the Company and deliver sustainable shareholder value. The Board sets the risk appetite for the Company and takes the lead in areas such as safeguarding the reputation of the Company and financial policy, as well as making sure we maintain a sound system of internal control and risk management (see pages 38 to 41). The Board’s full responsibilities are set out in the matters reserved for the Board, which were updated in January 2015. These are available on our website, together with other governance documentation.

Our Chairman is responsible for the leadership and management of the Board and its governance. He ensures the Board is effective in its role by promoting a culture of openness and debate, facilitating the effective contribution of all Directors and helping to maintain constructive relations between Executive and Non-executive Directors.

Our Chief Executive is responsible for the executive leadership and day-to-day management of the Company, to ensure the delivery of the strategy agreed by the Board. Through his leadership of the Executive Committee, he demonstrates commitment to safety, operational and financial performance.

Our Senior Independent Director acts as a sounding board for the Chairman and serves as an intermediary for the other Directors, as well as shareholders when required.

Independent of management, our Non-executive Directors bring diverse skills and experience, vital to constructive challenge and debate. Exclusively, they form the Audit, Nominations and Remuneration Committees, and have an important role in developing proposals on strategy.

Examples of Board focus during the year:

Board strategy session. In addition to time allocated during the year at Board meetings, in January the Board took part in a half-day interactive strategy session, involving a combination of full Board discussions and breakout groups. The Board considered questions raised by the business plan and recent strategic analysis, future opportunities for the Company including business development, mergers and acquisitions and how our core capabilities could be exploited.

The Board found the additional session extremely useful and suggested that further regular updates and discussions would help consolidate its thinking, in particular in relation to the development of a longer-term perspective on potential growth in other geographical areas.

European energy policy. The Board received updates on how changes in the EU will affect and influence the UK energy policy, including Electricity Market Reform, support for interconnectors and Carbon Capture and Storage.

The 2014 UK Winter Outlook. This annual publication confirmed that the Company was in a strong position in respect of gas in the UK, with no heightened concerns, but for electricity, margins were expected to be tight. Updates to the Board confirmed that the UK business had a good understanding of the issues and risks. A robust mitigation strategy, agreed with the UK Government, was approved and implemented.

Interconnector projects. In January, the Board received a presentation on Great Britain’s interconnector market and our pipeline of opportunities, including an overview of our two most advanced projects; potential new links to Belgium and Norway. Following feedback provided, the Board approved the final investment decision in relation to the Belgium interconnector in February 2015 and the interconnector with Norway in March 2015.

Emerging risks. The Board received a risk update paper including an overview of the framework that has been developed to track emerging risks and the resulting opportunities and/or threats. Additionally, the Board received an update on three themes that had emerged from the 2014 risk workshop to make sure that we were sufficiently prepared for ‘black swan’ events (catastrophic events of extremely high impact and extremely low likelihood).

Board and committee evaluation

As shown in the diagram below, we are in the third year of our evaluation cycle. This year an internal Board performance evaluation was conducted. The evaluation was ‘upward facing’ with questionnaires completed by non-Board members on the Executive Committee and regular attendees and presenters at Board meetings.

LOGO

The questions asked covered the following areas:

● time and focus for agenda items;

● the direction/guidance received to support the preparation

of papers and presentations;

● coverage by presenters on key topics;

● values and behaviours displayed by the Board and the

experience of attending Board meetings;

● level of challenge and questioning by the Directors; and

● diversity of thinking styles present on the Board.

The responses were collated into a confidential and non-attributable report which was presented to the Board in February. At this meeting, the Board considered the report and discussed its performance generally over the past year. The Board confirmed that it had worked well together as a unit, discharged its duties and responsibilities effectively over the year; and worked effectively with the Board committees.

Following this meeting, a draft action plan was prepared and considered by the Board in March. At this meeting, the Board agreed a number of actions for the forthcoming year, as set out below. Progress against these actions will be monitored throughout the year by the Board.

Environment

Optimise the boardroom layout to create a more inclusive environment for members and presenters.

Responsibility: Board members/Group General Counsel & Company Secretary

Continue to create a more open boardroom atmosphere and culture.

Responsibility: Chairman/Board members

Board discussions

Maximise the effectiveness of Board discussions.

Responsibility: Chairman/Executive Directors/Group General Counsel & Company Secretary

Use a diversity of thinking styles.

Responsibility: Chairman/Board members

Board focus

Continue to manage the strategy agenda.

Responsibility: Chairman/Chief Executive/Group General Counsel & Company Secretary

Progress against last year’s actions has been monitored through the year and a commentary against each action is set out opposite.

Committee evaluation

An evaluation of committee performance was also conducted by the chairman of each of the Board committees, as well as the Executive Committee. The process broadly followed that conducted by the Board with questionnaires being completed by regular attendees and presenters at the respective committee meetings. The process followed by the Nominations Committee was slightly different; see ‘The Committee in action’ box on page 57 for more details.

Following consideration of the results of the evaluation, each committee concluded that it had operated effectively throughout the year and agreed an action plan to further improve performance. Copies of each committee’s action plan were provided to the Board and it confirmed that it agreed that each committee had operated effectively.

Progress against the action plans will be monitored through the year by the respective committee and the Board.

Non-executive Director independence

The independence of the Non-executive Directors is considered at least annually along with their character, judgement, commitment and performance on the Board and relevant committees. The Board took into consideration the Code and indicators of potential non-independence, including length of service.

At year end, all of the Non-executive Directors, with the exception of the Chairman, have been determined by the Board to be independent.

Director performance

At a private meeting of the Non-executive Directors, Mark Williamson, as Senior Independent Director, led a review of Sir Peter’s performance. The Non-executive Directors, with input from the Executive Directors, assessed his ability to fulfil his role as Chairman and the arrangements he has in place, given he is also chairman of a FTSE 250 company and the Aircraft Carrier Alliance. They concluded that Sir Peter’s performance continued to be effective.

Sir Peter met each Director individually to discuss their contribution, performance over the year and training and development needs. Following these meetings, Sir Peter confirmed to the Nominations Committee that he considered that each Director demonstrated commitment to the role and their performance continued to be effective.

Following recommendations from the Nominations Committee the Board considers all Directors continue to be effective, committed to their roles and have sufficient time available to perform their duties. Therefore, in accordance with the Code, all Directors will seek election or re-election at the 2015 AGM as set out in the Notice of Meeting.


Area	Actions from last year’s review	Commentary
Decision making	All important matters requiring approval are to be brought to the Board for early input before a decision is needed. Responsibility: Chairman and Chief Executive	Sir Peter Gershon and Steve Holliday have regularly reviewed the forward business schedule with the Group General Counsel & Company Secretary over the year. The schedule is also included with the papers for each Board meeting to ensure Directors are aware of forthcoming topics for discussion. Following the thinking styles session in February 2015, the schedule was also reviewed to consider if any items could be brought forward early to allow Directors to contribute to thinking and direction at a preliminary stage of the debate.
Board discussions	Greater clarity about the scope of Board discussions to be provided in advance and Board members to be encouraged to question if not clear. Responsibility: Chairman	The Company Secretariat team engaged with external specialists in effective reporting to support the development of the information that goes to the Board. The new reporting framework has resulted in clearer, more concise papers, which has supported improved Board discussion and decision making. Following the successful implementation of the new reporting framework at Board level it has also been rolled out to the Board committees and the Executive Committee.
Degree of challenge	The Executive Directors to speak to the Chairman about what would make them feel more comfortable to challenge and debate, both with the Non-executive Directors and with their fellow Executive Directors at Board meetings. Responsibility: Executive Directors	In February, the Board reviewed progress against the 2013/14 action plan and noted that all Executive Directors felt empowered to input freely at Board meetings and that there was open and honest dialogue. The Chairman will continue to monitor this on an ongoing basis.
Board focus	A number of topics were identified that Directors felt needed additional focus by the Board at its meetings, for example cyber risk and the UK political landscape. Ways to improve the focus on each of these topics were discussed at the March 2014 Board meeting and specific actions were agreed and allocated. Responsibility: various Board members	The Board has taken into account the need for additional focus in certain areas and this has been reflected in the meeting agendas. Strategy: several papers focusing on strategy and growth have been received by the Board over the year in addition to the Board strategy session. Topics included: review of the UK gas market; US and other market opportunities; exploitation of core capabilities; expansion in and outside our core geographies; and a general update on the interconnectors. Political risk: political updates are provided in the Chief Executive’s report to the Board as appropriate. Additional papers on the politics of UK and US energy and a general update on politics in Europe have been presented to the Board and updates will continue to be provided as appropriate. Cyber risk: an update on cyber risk and security went to the Board and Audit Committee in September. At this meeting, the Board decided that responsibility for making sure there is an effective process for managing cyber security risk should be undertaken by the Audit Committee. The Board is scheduled to receive an in-depth presentation in November 2015. Relationship with UK and US regulators: updates on the meetings that take place between our Chairman and the Chairman of Ofgem are provided to the Board. Updates on US regulation and the meetings that take place with the US regulators are also provided to the Board in the Chief Executive’s report.
Effectiveness of the Board	Actions to improve Board effectiveness were proposed, for example: continue to improve the quality of Board papers; make sure in-depth items for Board consideration highlight the important issues to be discussed; and encourage reporting from management that incorporates more input from the Executive Directors. Responsibility: Chairman, Chief Executive and Group General Counsel & Company Secretary as appropriate	The new reporting framework described above will also help improve the effectiveness of the Board. As part of the new framework, executive owners of papers on the Board agenda have a greater input in to and ownership for the preparation of papers. Management are encouraged to meet with the executive owner at the start of the drafting process to discuss the framework for the paper and owners are required to review and sign off on the final paper prior to submission to the Board or committee.

Investor engagement

We believe it is important to maintain effective channels of communication with our debt and equity institutional investors and individual shareholders. This helps us to understand their views about the Company and allows us to make sure they are provided with timely and appropriate information on our strategy, performance, objectives, financing and other developments.

Institutional investors

We carry out a comprehensive engagement programme for institutional investors and research analysts. This includes meetings, presentations, webinars, attendance at investor conferences across the UK and US, and holding road shows in major investor centres across Europe, the US and Asia Pacific.

The programme provides the opportunity for our current and potential investors to meet with executive and operational management.

In the past year, our engagement programme has focused on clarifying our Group growth expectations and explaining to investors how we expect the Company to continue to perform under the RIIO price controls in the UK. These areas of focus have been reflected in our regular results presentations as well as in more detail during an investor seminar at our Castle Donington site.

In addition to these engagement activities, we also held a stewardship meeting in July last year. The event provided major investors with an understanding of our performance and an insight into the operation of our Board with a particular focus on the work of our Remuneration and Audit Committees. The event also provided the opportunity for attendees to ask questions and meet members of the Board and for our Non-executive Directors to further develop their understanding of our shareholders’ views and concerns. A copy of the presentation given on the day is available in the Investors section of our website.

Sir Peter also contacted our major shareholders in April 2015 to offer them the opportunity to meet him or the chairman of the Remuneration Committee, Jonathan Dawson, to discuss the Board changes that have taken place during the year and the associated remuneration arrangements.

The Board receives regular feedback on investor perceptions and opinions about the Company. Specialist advisors and the Director of Investor Relations provide updates on market sentiment.

Each year, the Board receives the results of an independent audit of investor perceptions. Interviews with key investors were carried out to establish their views on the performance of the business and management. The findings and recommendations of the audit were discussed in depth by the Board.

Debt investors

Over the last year representatives from our treasury team, together with other senior managers from across the business, have met with debt investors in Europe, Canada and the US to discuss various topics such as the full-year results.

We also communicate with our debt investors through regular announcements and the debt investor section of our website. This contains bond prospectuses, credit ratings, materials relating to the retail bond issued in 2011 and subsidiary year-end reports. The website also contains information about the long-term debt maturity profile, so investors can see our future refinancing needs.

Individual shareholders

Engagement with individual shareholders, who represent more than 95% of the total number of shareholders on our share register, is led by the Group General Counsel & Company Secretary. Shareholders are invited to learn more about the Company through the exhibits at our AGM and the shareholder networking programme.

The shareholder networking programme includes visits to UK operational sites and presentations by senior managers and employees over two days. UK resident shareholders can apply to take part online via the Investors section of our website.

Annual General Meeting (AGM)

Our AGM will be held on Tuesday 21 July 2015 at The International Convention Centre in Birmingham and broadcast via our website. The Notice of Meeting for the 2015 AGM, available on our website, sets out in full the resolutions for consideration by shareholders, together with explanatory notes and further information on the Directors standing for election and re-election.

How our Board operates

The Chairman sets the Board’s agenda in line with its responsibilities as set out in the matters reserved for the Board. Consideration is also given to the main challenges and opportunities facing the Company, making sure adequate time is available to discuss all items, including strategic issues.

To support discussion and decision making, Board and committee members receive papers sufficiently in advance of meetings so that they can prepare for and consider agenda items. Additionally, the Chairman holds a short meeting with the Non-executive Directors before each Board meeting to discuss the focus of the upcoming meeting as well as afterwards to share feedback and discuss the dynamics of the meeting. Similarly, the Chief Executive holds a short meeting with the Executive Directors and other senior management in attendance and shares the feedback from these meetings with the Chairman.

As set out in the table of actions from last year’s Board and committee evaluation process, during the year we engaged external specialists to review our current papers and develop a new reporting framework for the Board and its committees. This has resulted in clearer more concise reports, allowing more time for discussion and questions.

Board membership and attendance

Attendance is expressed as the number of meetings attended out of the number possible or applicable for the individual Director during the year to 31 March 2015.

Our Board and its committees

The Board delegates authority to its committees to carry out certain tasks on its behalf, so that it can operate efficiently and give the right level of attention and consideration to relevant matters.

The role and responsibilities of the committees are set out in their respective terms of reference, available on our website. The committee structure, delegation and reporting lines are set out in the diagram below.

In addition to the vertical lines of responsibility and reporting, the committees communicate and work together where required. For example, on some risk matters the SEH Committee collaborates with the Audit Committee. These lines of communication are shown in the diagram below.

Committee agendas and schedules of items to be discussed at future meetings are prepared in line with the terms of reference of each committee and take account of other topical matters.

At committee meetings, items are discussed and, as appropriate, matters are endorsed, approved or recommended to the Board by the committee. Following meetings, the chairman of each committee provides the Board with a summary of the main decisions and discussion points so the non-committee members are kept up to date.

Below the Board committees are a number of management committees, including the Executive Committee.

The Executive Committee has responsibility for making management and operational decisions about the day-to-day running of the Company. Further information on some of the management committees, including the membership and operation of the Executive Committee, is set out on pages 58 and 59.

Reports from each of the Board committees together with details of their activities during the year, are set out on the following pages.

Audit Committee

LOGO

Role

Oversees the Company’s financial reporting, and internal controls and their effectiveness, together with the procedures for identifying, assessing and reporting risks. It also oversees the services provided by the external auditors and their remuneration.

Review of the year

Challenging management on the action they are taking to continue to improve the US financial controls environment has remained a focus for the Committee over the past 12 months. Although there is work still to do, I am pleased to report we are now seeing steady progress in this area.

The US leadership team has been strengthened with the appointment of a new US Chief Financial Officer (CFO). The Finance Director and the US CFO have continued to keep the Committee up to date on progress with regular reports throughout the year on further proposed improvements and priorities.

The past year has also seen two other key appointments – a new Head of Corporate Audit (approved by the Committee in accordance with its terms of reference) and a new Head of Assurance. The Committee has received reports from both individuals on their initial observations of their respective functions and proposed changes and priorities for the year.

Following the delegation by the Board for oversight of risk management in relation to cyber security, the Committee received its first update from internal (corporate) audit on the process for identifying, mitigating, monitoring and responding to cyber security risks in March.

The Committee has been briefed on the changes to the regulatory environment, in particular the audit tender regulations published by the Financial Reporting Council, the implications of the Competition and Market Authority Order and the final European Commission regulations. We discussed and considered the timing of a tender for the external audit and agreed that an audit tender process should be run later this year. See page 53 for further details.

Committee membership has also undergone some changes. Maria Richter stepped down from the Board at the 2014 AGM. In 2015 we have said goodbye to Philip Aiken and welcomed Paul Golby and Therese Esperdy to the Committee in February and April respectively. I would like to thank Phil for his contribution and support to the Committee over the last six years. We are looking forward to working with Paul and Therese over what will be another busy year.

Significant issues

The most significant issue the Audit Committee considered in relation to the financial statements during the year were the US financial controls. The Committee also considered the presentation of exceptional items, the treatment of the liability management programme costs and accounting for agreed legal settlements. More detail is provided later in the report.

Other matters reviewed

Examples of other matters the Audit Committee reviewed:

The new Group consolidation system. Regular progress updates on the implementation which is expected to go live later this year.

Lessons learnt from the March 2014 year-end audit. The Committee noted the detailed plans produced by management and the external auditors to deliver a more efficient March 2015 year-end process, including the timing of certain audit testing and the approach to subsidiary statutory and regulatory accounts.

Sarbanes-Oxley Act 2002 testing and attestations. The Committee received regular updates on the status of testing and considered the impact of deficiencies reported at the May 2014 meeting. During the year, the Company adopted the revised framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Subsequently, a review of all internal controls of financial reporting was undertaken to ensure compliance with the updated framework. See page 41 for the Company’s statement on the effectiveness of internal control over financial reporting.

Accounting for rate regulated activities. The Committee endorsed management’s response to the discussion paper issued by the International Accounting Standards Board in September 2014 and believe that guidance should be introduced that results in the IFRS financial statements of the Company more closely reflecting its economic performance and position.

Fair, balanced and understandable. The requirement of the Code to ensure that the Annual Report and Accounts, taken as a whole, is fair, balanced and understandable in the context of the applicable accounting standards and confirmed this view to the Board.

Interim Management Statements (IMS). The Board’s decision to cease the publication of an IMS and the impact on the traditional role of the Committee. Depending on the content of future market updates, the Committee will review these prior to publication.

Cyber security risk management. A paper from internal

(corporate) audit on the status of our cyber security risk management and external good practice in September 2014. In setting the scope of its new responsibilities, the Committee considered the level of assurance currently provided by internal (corporate) audit and other assurance providers and the frequency and extent of information received. Subsequently, the Committee’s terms of reference were amended to include this additional responsibility in relation to the review of the governance processes over cyber security risk and the Committee now receives a regular update from the Head of Corporate Audit.

Risk management. Half-yearly updates on the management of key risks faced by the Company including changes to the corporate risk profile to reflect Executive Committee risk management discussions.

Committee membership and attendance table Attendance is expressed as the number of meetings attended out of the number possible or applicable for the individual Director during the year to 31 March 2015. Biographical details and experience of Committee members are set out on pages 178 and 179.		Summarised below are the issues which attracted the most focus, and time, of the Committee in relation to the financial statements during the year. US financial controls. The Committee has continued to devote a significant amount of time challenging management on the action they are taking to continue to improve the US finance control environment. There has been continued focus on embedding the enterprise resource planning system in the US and the benefits this system now brings. The Committee has received regular updates from management on progress against the measures taken to remediate US financial control deficiencies. In October, a new US CFO was appointed to lead the US finance team. She initiated a granular review of the US finance function to understand the current service levels and key learnings from prior initiatives, including the successes as well as initiatives that did not fully achieve their goals. The outputs from this review were incorporated into a new US finance function initiative which is intended to address the root cause of issues identified by the review and simplify and standardise processes. In January 2015, the Committee received a presentation on the initiative to understand the approach being taken, the stages involved and the underlying issues that the initiative was aiming to resolve. Management sought input and feedback from the Committee on the direction, focus and timing of the proposed initiative. The Committee discussed the proposal and asked questions about the initiative before approving the approach. Regular updates will be provided to the Committee through the year so that progress can be monitored. During the year, the Committee challenged management in the US on its regulatory filing obligations, noting that due to the system implementation issues, not all filings were made on time. Management presented and, during the course of the year, delivered on a detailed plan to complete the filings and remediate the process. All regulatory filings are now up to date and management communicated with the regulators throughout the process. Presentation of exceptional items. At the half year and year end, the Committee examined an analysis of items to be classified as exceptional to make sure the items did not include income or costs relating to the underlying business performance. In particular, the Committee considered the treatment of the liability management programme costs at the year end. Management proposed that the costs associated with the debt redemptions should be treated as exceptional as they were one-off, significant and outside the ordinary course of business. To include this cost in underlying finance costs would otherwise distort users’ understanding of the business performance. This proposal was in line with the exceptional items accounting policy in the Annual Report and Accounts and the historical treatment of debt redemption costs. The Committee agreed that the classification of this item was appropriate. See note 4 footnote 8 on page 104.

1. Paul Golby joined the Committee on 25 February 2015. 2. Philip Aiken stepped down from the Board with effect from 25 February 2015. 3. Maria Richter stepped down from the Board with effect from 28 July 2014. Therese Esperdy was appointed to the Committee with effect from 22 April 2015. Experience The Board has determined that Mark: ● has recent and relevant financial experience; ● is a suitably qualified audit committee financial expert within the meaning of the SEC requirements; and ● is independent within the meaning of the New York Stock Exchange listing rules. Financial reporting The Committee monitors the integrity of the Company’s financial information and other formal documents relating to its financial performance and makes appropriate recommendations to the Board before publication. An important factor in the integrity of financial statements is making sure that suitable and compliant accounting policies are adopted and applied consistently on a year-on-year basis and across the Company. In this respect, the Committee also considers the estimates and judgements made by management when accounting for non-standard transactions, including the treatment of exceptional items. Two examples of these are set out below. These considerations are supported by input from other assurance providers such as the group controls, risk management and ethics and compliance teams, the business separation compliance officer, internal (corporate) audit and the SEH Committee, as well as our external auditors. In addition, the Committee also considers reports of the Disclosure Committee. See page 59 for more information on the role of the Disclosure Committee. The Committee reviews and approves the external audit plan annually (see page 53) and, as part of this, considers the significant risks upon which the external auditors will focus their audit. The independent auditors’ report (pages 79 to 84) highlights areas of focus, including some of the issues that the Committee discussed during the year. Other risks, including the accuracy and valuation of treasury derivative transactions, accounting for pension obligations, accuracy of capital expenditure, revenue recognition and valuation of environmental provisions were not considered in detail by the Committee during the year as nothing significant arose that warranted Committee attention.

Corporate Governance

Corporate Governance continued

Accounting for agreed legal settlements. During the year, the Company reached negotiated settlement agreements in a legal case. The Company was awarded a total of £113 million (including allowance for legal costs incurred). Due to the size of the impact on the income statement, the Committee agreed with management’s decision that this was not considered to be exceptional for the year. The Committee reviewed and challenged the classification of the settlements and agreed that £56 million be recognised in the income statement in the year, with the remainder credited to property, plant and equipment. Management is waiting for confirmation from Ofgem of the regulatory treatment of these awards under RIIO.

Confidential reporting procedures and whistleblowing

The integrity of the financial statements is further supported by the confidential reporting and whistleblowing procedures we have in place. The Committee reviews these procedures once a year to make sure that complaints are treated confidentially and that a proportionate, independent investigation is carried out in all cases.

Internal (corporate) audit

The corporate audit function provides independent, objective assurance to the Audit, SEH and Executive Committees on whether our existing control and governance frameworks are operating effectively in order to meet our strategic objectives. Assurance work is conducted and managed in accordance with the Institute of Internal Auditor’s International Standards for the Professional Practice of Internal Auditing and Code of Ethics.

To keep the Committee informed of trends identified from the assurance work and to update on the progress against the corporate audit plan, the Head of Corporate Audit reports to the Committee at least twice each year. These reports present information on specific audits, as appropriate, summarise common control themes arising from the work of the team and update on progress with implementing management actions. Where control issues are identified, senior leaders may be invited to attend Committee meetings to provide a commentary around the actions they are taking to improve the control environment within their area of responsibility.

In order to meet the responsibility and objectives set out in the Corporate Audit Charter, audits of varying types and scopes are performed as part of the annual corporate audit plan. The audit plan is based on a combination of risk-based and cyclical reviews, together with a small amount of work that is mandated, typically by US regulators.

Inputs to the audit plan include risk registers, corporate priorities, external research of emerging risks and trends and discussions with senior management to ensure that the plan aligns with the Committee and Company’s view of risk. The audit plan is considered and approved by the Committee annually.

External audit

The Committee is responsible for overseeing relations with the external auditors, including the approval of fees, and makes recommendations to the Board on their appointment and reappointment. Details of total remuneration to auditors for the year, including audit services, audit-related services and other non-audit services, can be found in note 3(e) of the consolidated financial statements on page 102.

Auditor independence and objectivity

The independence of the external auditors is essential to the provision of an objective opinion on the true and fair view presented in the financial statements.

Auditor independence and objectivity is safeguarded by a number of control measures, including:

●

limiting the nature and value of non-audit services performed by the external auditors;

●

ensuring that employees of the external auditors who have worked on the audit in the past two years are not appointed to senior financial positions within the Company in line with our internal code;

●

monitoring the changes in legislation related to auditor objectivity and independence to help ensure we remain compliant;

●

providing a business conduct helpline that employees can use to report any concerns, including those relating to the relationships between Company personnel and the external auditor;

●

the rotation of the lead engagement partner at least every five years;

●

PwC’s internal independence rules and processes which have been designed to exceed professional standards and focus on both personal independence and scope of services;

●

				Non-audit services provided by the external auditors In accordance with our policy, non-audit services provided by the external auditors above a threshold of £50,000 require approval in advance by the Committee. Below this threshold, all requests are approved in advance by the Finance Director and do not require Committee pre-approval. This reduces the administrative burden on the Committee. A full list of all Committee and Finance Director approved non-audit work requests is presented to the Committee annually to ensure the Committee is aware of all non-audit services provided. Additionally, the Committee receives quarterly reports from management on non-audit services and other consultants’ fees to monitor the types of services being provided and fees incurred. Approval for the provision of non-audit services is given on the basis the service will not compromise independence and is a natural extension of the audit or if there are overriding business or efficiency reasons making the external auditors most suited to provide the service. Certain services are prohibited from being performed by the external auditors, as required under the Sarbanes-Oxley Act 2002. Total non-audit services provided by PwC during the year ended 31 March 2015 were £0.9 million (2014: £1.7 million), which comprised 7% (2014: 13%) of total audit and audit-related fees (see note 3(e)). Total audit and audit-related fees include the statutory fee and fees paid to PwC for other services that the external auditors are required to perform, for example regulatory audits and Sarbanes-Oxley Act attestation. Non-audit fees represent all other services provided by PwC not included in the above. Non-audit services provided by PwC in the year included tax compliance services in territories other than the US (£0.4 million), the significant majority of which relates to the UK. The Committee considered that tax compliance services were most efficiently provided by the external auditors, as much of the information used in preparing computations and returns is derived from audited financial information. In order to maintain the external auditors’ independence and objectivity, management reviewed and considered PwC’s findings and PwC did not make any decisions on behalf of management.						Auditor appointment An annual review is conducted by the Committee of the level and constitution of the external audit and non-audit fees and the effectiveness, independence and objectivity of the external auditors. The annual review includes consideration of: ● audit quality and the external audit process globally; ● the auditors’ performance and delivery against the audit plan; ● the expertise of the firm and our relationship with them including the level of challenge; and ● the results of online questionnaires completed by the Chairman, Committee members, Executive Directors and senior representatives from the finance team. The questions focused on: the quality of service; sufficiency of resources; planning and execution of the audit; communication and interaction; and overall satisfaction. No material issues were identified. Following this year’s annual review, the Committee was satisfied with the effectiveness, independence and objectivity of the external auditors, and recommended to the Board their reappointment for a further year. A resolution to reappoint PwC and giving authority to the Directors to determine their remuneration will be submitted to shareholders at the 2015 AGM. Audit tender PwC have been the Company’s external auditors since the merger with Lattice Group plc in 2002, having been the incumbent external auditors of both the merging parties and the audit contract has not been put out to tender since then. Their performance has been reviewed annually by the Committee since that time. The Committee discussed the implications of the Competition and Market Authority Order requiring FTSE 350 companies to hold an audit tender every 10 years as well as the final European Commission (EC) regulations, which came into EU legislation in June 2014. The Committee noted that based on the EC transitional arrangements, the final year in which PwC can be appointed as the Group’s auditors is for the year ended 31 March 2020. At its meeting in May 2015, the Committee considered the timing of a potential tender for the external audit. The Committee considered the continued US financial controls improvement programme and the services we currently receive from other external audit firms that may be considered in a tender process. It concluded that, firstly, in order to ensure an orderly transition and secondly, to ensure compliance with the EC regulations on the provision of prohibited services, an audit tender process will be run later this year for the audit of the year ending 31 March 2018. PwC will not be invited to tender. No representatives from PwC were present during the Committee’s discussion of the options for a tender of the external audit. There are no contractual obligations restricting our choice of external auditors and we have not entered into any auditor liability agreement.
				Audit quality To maintain audit quality and provide comfort on the integrity of financial reporting, the Committee reviews and challenges the proposed external audit plan including the scope and materiality to make sure that PwC have identified all key risks and developed robust audit procedures and communication plans. The Committee also considers PwC’s response to accounting, financial control and audit issues as they arise, and meets with them at least annually without management present, providing the external auditors with the opportunity to raise any matters in confidence.

Risk management and internal control

The Audit Committee monitors the effectiveness of the risk management and internal control processes during the year through the biannual reports it receives and reports to the Board on the outcome. The review covers all material controls, including financial, operational and compliance controls. Please see page 41 for further details about the review of effectiveness.

In support of our compliance with the New Code, reporting to the Audit Committee on risk management and internal control has been reviewed by the Board and refinements will be adopted for the financial year 2015/16.

Details of our internal control systems, including those relating to the financial reporting process, can be found on pages 38 to 41 and page 173.

Risk management

The Executive Committee discusses the principal risks faced by the Company and updates the corporate risk profile every six months. The approved profile is subsequently shared with the Audit Committee, along with US and UK regional risk profiles, as part of our continuous risk management process.

To continuously improve and remain at best practice levels, the risk management team reviews risk process standards, emerging trends and concepts being driven by the main consultancy firms and seeks to apply these as appropriate. The standards issued by the COSO and the international risk standard ISO 31000 continue to inform the principles of our risk management process.

During the year, we adopted the revised framework issued by the COSO for our internal controls over financial reporting. This introduced specific principles to cover fraud risk assessment and information technology. We also reviewed the procedures for the identification, assessment, mitigation and reporting of risks.

Further details of our risk management systems can be found on pages 38 to 41 and our risk factors are described in full on pages 173 to 176.

Compliance management

Compliance management has been integrated into a new Global Assurance team which incorporates ethics, risk management, licence management and records management with a view to improving visibility and reporting in all areas.

Biannual reports to the Committee focus on compliance with external legal obligations and regulatory commitments. During the year, the Committee requested that additional detail be added to the reports against each of the actual or potential non-compliance items identified to show the person responsible and provide a summary of the actions being taken to resolve the actual or potential non-compliance.

The Committee also received annual reports on the Company’s anti-bribery procedures and whistleblowing procedures and reviewed their adequacy. It noted that no material instances of non-compliance had been identified.

Going concern

Our going concern process is an extension of our business planning process, and is further supplemented by our annual budget and other liquidity risk management controls. Our five year business plan and one year budget were reviewed and approved by the Board at its meetings in November 2014 and March 2015 respectively. The Finance Committee provides ongoing oversight of our liquidity policy, which requires us to maintain sufficient liquidity for a rolling 12 month period.

Given our business model, current regulatory clarity and other factors impacting our operating environment, and the robustness of our business planning process and scenario analysis, we have concluded the going concern assessment period is the five years ending 31 March 2019, in line with our business plan. We will reassess this period annually in light of developments in our operating environment, business model and strategic priorities.

Our business plan considers the significant solvency and liquidity risks involved in delivering our business model in light of our strategic priorities. The business plan models a number of upside and downside scenarios, derived from the risks and opportunities identified, and determines the impact these would have on our results and financial position over the five year period. In addition, we have reviewed and challenged a number of worst case scenarios and their possible remediation.

Our business model calls for significant capital investment to maintain and expand our network infrastructure. To deliver this, our business plan highlights that we will need to access capital markets to raise additional funds from time to time. We have a long and successful history in this regard. Our business plan also models various KPIs used by lenders and credit rating agencies in assessing a company’s credit worthiness. These models indicate that we should continue to have access to capital markets at commercially acceptable interest rates throughout the five year period. To monitor and control risks around access to capital markets, we have policies and procedures in place to help mitigate, as far as possible, any risk of a change in our credit ratings and other credit metrics.

Having made enquiries and reviewed management’s assessment of the going concern assumption, the Directors have a reasonable expectation that the Group has adequate resources to continue in operational existence for the period of the going concern assessment. For this reason, the Directors are satisfied that, at the time of approving the financial statements, it is appropriate to continue to adopt the going concern basis in preparing the consolidated and individual financial statements of the Company.

More detail on our financial risks, including liquidity and solvency, is provided in note 30 to the consolidated financial statements. There have been no major changes to the Group’s significant liquidity and solvency risks in the year.

Finance Committee

Matters considered

LOGO

Role

Sets policy and grants authority for financing decisions, credit exposure, hedging and foreign exchange transactions, guarantees and indemnities subject to the risk appetite approved by the Board. It also approves other treasury, tax, pension funding and insurance strategies and, if appropriate, recommends these to the Board.

Review of the year

My first eight months as chairman have been busy but enjoyable. In July, we said goodbye to Maria Richter who stepped down from the Board. I would like to thank her for her contribution to the Committee and for her guidance and support during the handover period.

As part of my induction to the Board and before taking over as chairman of the Committee, I met employees involved in the work of the Committee from finance, treasury, tax, pensions and insurance in the UK and US. I also had several opportunities to meet the wider UK and US tax, insurance and treasury teams which has furthered my understanding of our treasury operations.

This year, we continued to focus on funding plans to take into account international debt market conditions. The Committee reviewed and agreed a liability management programme which resulted in the repurchase of £0.9 billion of bonds.

The Committee also received regular updates on negotiations in relation to the European Investment Bank (EIB) loan before agreeing the £1.5 billion loan agreement with the EIB in November 2014.

We also considered the financial headroom policy. During the financial crisis, the Committee approved a policy to hold 12 months of liquidity and a minimum sum as cash or liquid assets. The Committee noted that the Group’s liquidity was monitored on a regular basis both internally and externally and took into consideration the sources of liquidity. In light of the improved access to liquidity the Committee approved a simplification of the policy.

External advisors have presented to the Committee throughout the year, including a credit rating agency on their methodology and an update from insurance brokers on the global property insurance market, including the current trading environment, market selection, new risks, client trends and the future outlook for insurance.

For the year ahead, we will focus on our funding needs, liquidity management, alternative sources of funding and pensions investment strategy.

Examples of matters the Committee considered during the year include:

● funding requirements and financing for the

business plan;

● setting and reviewing treasury policies;

● treasury performance updates provided at each

meeting;

● UK and US tax updates;

● US energy procurement activities;

● annual update on the electricity and gas trading

activities in the UK;

● credit rating agencies’ view on the Company;

● foreign exchange policy;

● interest rate risk management;

● the draft going concern statement for the half

and full-year results prior to consideration by the

Audit Committee and Board;

● pensions updates, including funding of the

Company’s pension deficits; and

● insurance renewal strategy.

Evaluation of Committee performance

The Committee performance evaluation process this year was an upward facing process undertaken by non-Committee members and regular attendees/presenters. This was in line with the process adopted by the other committees (except the Nominations Committee).

The Committee concluded that it had operated effectively throughout the year and agreed an action plan for 2015/16 to further improve performance.

An update on the evaluation including the draft Committee action plan was reported to the Board in May 2015. Progress against the action plan will be monitored through the year by the Committee and the Board.

Safety, Environment and Health Committee

Matters considered

LOGO

Role

The Committee reviews the strategies, policies, initiatives, risk exposure, targets and performance of the Company and, where appropriate, of its suppliers and contractors in relation to safety, environment and health. It monitors the resources we use for compliance and driving improvement in these areas and reviews investigations into major incidents.

Review of the year

Following Philip Aiken’s departure from the Board at the end of February, I have taken over as chairman of the Committee. I have been a member of the Committee for the last three years and over this time we have seen the Company make significant progress in process safety management and the safety performance of both the UK and US businesses, with the US closing the gap on the UK in terms of employee and contractor LTIs. I hope to see further progress in these areas going forwards.

We welcomed Andrew Bonfield to the Committee at the beginning of the year. Andrew is a member of the Chief Financial Officers Leader Group of the Accounting for Sustainability (A4S) project, which challenges organisations to demonstrate the commercial rationale for incorporating sustainability into decision making and to manage the related risks and opportunities. He also chairs the Company’s Engineering Assurance Committee, which now reports on a six monthly basis to the Committee.

We have continued to focus on process safety and establishing a safety management system across both our UK and US businesses. We have spent time looking at the risks relating to our US LNG assets and the measures being introduced to address these (see ‘The Committee in action’ below).

Following a fatality involving a contractor at our Rhode Island gas distribution business, we spent time with senior local management considering the causes of the incident and how best to ensure that safety procedures are understood and complied with at all times, by both employees and contractors.

In terms of environmental matters, we have continued to monitor our strategy and approach to sustainability. In particular, we have looked at how we are working with governments and bodies such as the US Environmental Protection Agency to influence regulations that directly impact on our business.

We also considered the Health and Wellbeing strategy and the work being done on data management, improved line management training and providing support and guidance to employees to address levels of absenteeism.

Examples of matters the SEH Committee reviewed during the year include:

● ongoing monitoring of safety performance and

significant incidents in both the US and the UK;

● lessons learnt and steps taken following a

fatality of a member of the public in the UK in

April 2014 and a contractor fatality in the US in

November 2014;

● in-depth reviews of incidents in both the UK

and US gas businesses where failure to follow

due process led to high pressure releases

placing the employees involved in potential

danger;

● compliance with US gas pipeline safety

regulations in the light of new regulations and

evolving enforcement policies by our

regulators;

● review of the role and set up of the Engineering

Assurance Committee which was formed last

year to promote the application of common,

consistent, engineering assurance

methodologies across the Company;

● conclusion of a review of the interfaces

between our IT systems and safety processes;

● the use of bars in the UK gas distribution

business for the break up and removal of gas

mains below 6” in diameter, looking at safety

issues and available alternatives; and

● climate change strategy, including performance

against emissions targets and carbon budgets.

The Committee in action

US LNG assets

As part of its focus on process safety and the management of major hazard assets, the Committee has spent time with the US business looking at the risks surrounding its LNG assets, as a number of these assets are located close to areas that have pockets of relatively dense population.

The Committee considered the possible risk reduction measures for two key sites, Commercial Point in Massachusetts and Providence in Rhode Island, where the risk levels had been established to be highest. Philip Aiken visited both sites and members of the Committee received additional training on LNG process safety risks and the relevant risk assessment methodologies.

Over the following 12 months the Committee, through regular reports, oversaw the implementation of the measures proposed, including the installation of automatic shutdown mechanisms which was completed at these plants in June 2014. The Committee also reviewed the proposed timetable for dike redesign and construction to improve containment of LNG escapes in the event of an incident and recommended completion be brought forward by several months.

process;

● Board and committee membership following

changes to the composition of the Board;

● the executive succession planning focusing on the

identification, development and readiness of

successors to the Executive Committee in particular;

Role

Responsible for considering the structure, size and composition of the Board and committees, and succession planning. It also identifies and proposes individuals to be Directors and executive management reporting directly to the Chief Executive, and establishes the criteria for any new position.

● review of Sir Peter’s performance as Chairman, led

by Mark Williamson, the SID;

● the proposed structure for the UK business;

● feedback on the key issues to be covered by the

talent update paper to the Board to provide focus for

the discussion; and

● the Committee’s performance; see ‘The Committee

in action’ below.

Review of the year

Succession planning continues to be an important responsibility of this Committee, and is reflected in the time spent on the topic this year. The process of building a strong and effective Board requires a good balance of continuity and refreshment.

As described in my foreword to the Corporate Governance report, during the year we have undertaken a rigorous recruitment process to select Dean Seavers as a successor to Tom King, a key appointment to the Board. Details of our process are included later in this report on page 58.

Balance is an important consideration in recruitment, not only in terms of the number of Executive and Non-executive Directors, but also in terms of the range of expertise and backgrounds. In setting the specification of the role, we reviewed the existing skills, experience and diversity of the Board, including diversity of thinking styles, and identified areas that were essential or highly desirable in potential candidates.

The fit with current membership and how the individuals combine to add value was also taken in to account in the decision making process. Dean brings valuable skills and experience that complement the existing Board members and provides a fresh perspective and challenge to Board discussions.

Last year we set out eight measurable objectives to support our Board diversity policy. We have conducted our annual review of the policy and I am pleased to report that we are on track against the objectives we set.

We currently have 27.3% women on our Board and 24.1% in our senior management population. We have included examples of how the Company supports women throughout our businesses on page 25.

Following the changes in Board membership, the composition of the committees was also reviewed. Paul Golby has become chairman of the SEH Committee and joined the Audit Committee as a member in place of Philip Aiken to maintain continuity between the two committees.

The Committee also considers succession planning over the long-term, for both Executive and Non-executive positions, to ensure that we have the right mix of skills and experience as the Company evolves and so that change can be effectively managed.

The Committee in action

Evaluation of Committee performance

The Nominations Committee performance evaluation process took a slightly different approach to the evaluations for the Board and other committees. Committee members were asked to provide feedback on how effectively it had dealt with the main topics considered in the last year and its duties and responsibilities; how it had worked together as a unit; and the strengths and weaknesses of the Committee and how these could be addressed by the action plan.

Following consideration of the Committee’s performance over the year and the above questions, the Committee concluded that it had operated effectively throughout the year and agreed an action plan for 2015/16, which included refinements to the appointment process of future non-executive and executive directors to make sure that we continuously improve our robust approach, including briefings for Non-executive Directors on their role in the selection and appointment of executive directors.

Additionally, the time spent discussing senior executive succession planning will be reviewed to make sure that Committee input continues to be provided, as appropriate, to support senior appointments.

An update on the evaluation including the draft Committee action plan was reported to the Board in May 2015.

		Appointment process Executive Director The recruitment process undertaken for the appointment of Dean Seavers was formal, rigorous and transparent. The Nominations Committee appointed Korn Ferry as the search consultancy, and the following process was undertaken: ● with input from the Committee members, a role and person specification was prepared; ● Korn Ferry conducted initial searches, meeting eight potential candidates and shortlisted three candidates; ● a series of interviews of the shortlisted candidates were conducted by Sir Peter Gershon, Steve Holliday, Andrew Bonfield, Mark Williamson, Nora Mead Brownell and Mike Westcott (the Group Human Resources Director); ● following a review of the combined ratings from all the interviewers, the Nominations Committee selected two candidates for further consideration; ● final interviews with the two candidates were carried out by Steve Holliday, Nick Winser, John Pettigrew, Nora Mead Brownell and members of the Executive Committee; ● following discussion, the Nominations Committee recommended Dean Seavers as its preferred candidate for appointment to the Board, noting that all members had met Dean; and ● the Board approved the appointment as recommended. In addition to providing external search consultancy services to the Company, Korn Ferry also provided IT consultancy, e-learning services and coaching for senior management. John Pettigrew was appointed to the Board with effect from 1 April 2014. A description of the process undertaken in relation to his appointment was provided in the 2013/14 Annual Report and Accounts. Board diversity and the Davies Review At National Grid, we believe that creating an inclusive and diverse culture supports the attraction and retention of talented people, improves effectiveness, delivers superior performance and enhances the success of the Company. Our Board diversity policy promotes this and reaffirms our aspiration to meet and exceed the target of 25% of Board positions being held by women by 2015, as set out by Lord Davies. We currently have 27% women on our Board and 22% women on our Executive Committee. The number of women in senior management positions and throughout the organisation is set out on page 25 along with examples of the initiatives to promote and support inclusion and diversity throughout our Company. During the year, the Committee reviewed the Board diversity policy and progress made against the objectives which were approved to support the implementation of the policy as set out below: The Board aspires to exceed the target of 25% of Board positions to be held by women by 2015. Objective met – we currently have 27% women on our Board. All Board appointments will be made on merit, in the context of the skills and experience that are needed for the Board to be effective. Objective met – John Pettigrew and Dean Seavers were appointed on merit. We will only engage executive search firms who have signed up to the Voluntary Code of Conduct on gender diversity. Objective met – Korn Ferry are signed up to the code.						Where appropriate, we will assist with the development and support of initiatives that promote gender and other forms of diversity among our Board, executive and other senior management. Objective met – see page 25 for further details. Where appropriate, we will continue to adopt best practice in response to the Davies Review. Ongoing – as appropriate. We will review our progress against the Board diversity policy annually. Objective met – ongoing. We will report on our progress against the policy and our objectives in the Annual Report and Accounts along with details of initiatives to promote gender and other forms of diversity among our Board, Executive Committee and other senior management. Objective met – ongoing. We will continue to make key diversity data, both about the Board and our wider employee population, available in the Annual Report and Accounts. Objective met – ongoing. Progress against the objectives and the policy will continue to be reviewed annually and reported in the Annual Report and Accounts. Executive Committee Led by the Chief Executive, the Executive Committee oversees the safety, operational and financial performance of the Company. It is responsible for making day-to-day management and operational decisions it considers necessary to safeguard the interests of the Company and to further the strategy, business objectives and targets established by the Board. It approves expenditure and other financial commitments within its authority levels and discusses, formulates and approves proposals to be considered by the Board.
								The Committee in action During the year, the Executive Committee reviewed and discussed a proposed joint venture with the Berkeley Group. The strategic aim was to unlock value in our surplus London property portfolio and transform redundant land to help meet the current housing and commercial needs of London. The proposal was initially presented to the Committee for consideration. Feedback was provided, with requests for further information and clarification on aspects of the proposal. Committee members then worked closely with management and specialist teams to develop the proposal. The proposal returned to the Committee for review and was approved for recommendation to the Board. Following presentation and review at its November meeting, the Board gave final approval of the arrangement. The joint venture, called St William Homes, was formally announced in November.
								The nine Committee members have a broad range of skills and expertise, which are updated through training and development. Some members also hold external non-executive directorships, giving them valuable board experience. The Committee officially met 12 times this year, but the members interact much more regularly. Those members of the Committee who are not Directors regularly attend Board and committee meetings for specific agenda items. This means that knowledge is shared and every member is kept up to date with business activities and developments.

Management committees To help make sure we allocate time and expertise in the right way, the Company has a number of management committees, which include the Disclosure Committee, Global Ethics and Compliance Committees and the Global Retirement Plan Committee. These management committees provide reports, where relevant, to the appointing committee in line with our governance framework on the responsibilities they have been delegated. Disclosure Committee The role of the Disclosure Committee is to assist the Chief Executive and the Finance Director in fulfilling their responsibility for overseeing the accuracy and timeliness of the disclosures made – whether in connection with our presentations to analysts, financial reporting obligations or other material stock exchange announcements, including the disclosure of price sensitive information. This year the Committee met to consider the announcements of the full and half year results and the July 2014 Interim Management Statement (IMS) and reported on the matters arising to the Audit Committee. In doing so it spent time considering the Company’s disclosure obligations relating to identified weaknesses in internal controls over financial reporting in the US, and whether these should be considered material for the Company as a whole, and the process for the publication of unaudited year-end financial results. The Committee also considered the Company’s disclosure obligations relating to delays in cable manufacturing and the consequential impact on capital expenditure for the West Coast HVDC Link as well as the accounting treatment and disclosure for agreed legal settlements. Following the removal of the requirement to publish an IMS, the Committee will review the investor newsletters prior to publication to the extent they contain updated technical guidance on the Company’s performance or other price-sensitive information.	The Committee also reports the results of its evaluation of the effectiveness of the Company’s disclosure controls to the Audit Committee. The Committee is chaired by the Finance Director and its members are the Group General Counsel & Company Secretary, the Global Tax and Treasury Director, the Group Financial Controller, the Director of Investor Relations, the Head of Corporate Audit and the Deputy Group General Counsel, with other attendees as appropriate.

		Directors’ Remuneration Report

Annual statement from the

Remuneration Committee chairman

Overview

Last year, over 96% of shareholders voted to approve a new remuneration policy for National Grid. Although the policy is not subject to shareholder vote again this year, we have reprinted it on pages 62 to 68 for ease of reference. The new policy followed an extensive review by the Remuneration Committee to assess how the remuneration framework needed to change to reflect developments in National Grid’s business – the introduction of a new eight year regulatory framework in the UK (RIIO), and the continued evolution of our US business.

National Grid’s shareholder returns are earned progressively through two main contributing factors. First, through careful management of long-term assets and their financing; and second, by building for future returns through a substantial, continuing and well-executed programme of long-term capital investment in regulated and non-regulated operations. Our aim was to make sure that shareholders’ and executives’ longer-term interests are clearly aligned through properly focused incentive plans and by requiring executives to have a significant shareholding in the Company. In summary, we concluded that:

● there should be a significant weighting towards longer-term incentives and longer-term shareholding exposure for senior management through a reduction in the potential maximum Annual Performance Plan (APP) level, and an increase in the potential maximum Long Term Performance Plan (LTPP) level;

● the bulk of remuneration should be paid in National Grid shares;

● senior executives should be required to have a significant mandatory shareholding (500% of pre-tax salary for the CEO and 400% for other Executive Directors) and that no shares could be sold (except for meeting the tax on vesting) until the mandatory shareholding level was attained;

● shares that vested under the LTPP, following the three year performance measurement period, had to be retained for a further two years, irrespective of whether the mandatory shareholding level had been attained; and

● the metrics for LTPP performance should change to Return on Equity (RoE) and value growth. RoE provides a measurement of management’s performance in generating profit from the business, and value growth captures management’s longer-term performance in creating shareholder value.

We were clear that the new arrangements must only deliver higher rewards when executives had achieved a commensurately stronger performance. We believe that we have set threshold, target and stretch levels of performance accordingly. We also wanted to make sure that our commitment to increasing the annual dividend by at least RPI for the foreseeable future – an important element in shareholders’ total return – was linked to executive remuneration. The Committee, therefore, made it explicit that it had the power to reduce LTPP vesting if the Company failed to honour the dividend commitment, irrespective of the level of vesting resulting from the performance against the LTPP targets set by the Committee.

The Remuneration Committee believes that the policy endorsed last year by shareholders is fully aligned with the Company’s strategy and with the experience of shareholders in general. It also believes that, based on our appraisal of performance against our demanding targets to date, the policy is not inflationary compared with previous arrangements. We will, however, continue to reassess remuneration policy and targets for future awards so that we can remain confident they are still meeting the objectives set by the Committee.

Performance for the year

APP

National Grid has achieved another year of strong financial performance in the UK and solid performance in the US with record investment levels. The financial measures for the APP were adjusted EPS and either Group RoE, UK or US RoE depending on role. At 60.6 pence, the adjusted EPS figure for APP was up 6.3 pence (12%) on 2013/14. The EPS figure used for the APP calculation differs slightly to the reported EPS figure of 58.1 pence as it is adjusted for the impact of timing and actuarial assumptions on pensions and other post-employment benefits (OPEB). Group RoE was 11.8%, ahead of last year’s 11.4% result. Our UK RoE was 14.3%, including the benefit of a legal settlement referred to in the report of the Audit Committee on page 52. In the US, our RoE was 8.4%, which was slightly down on last year. As a result, in respect of financial metrics for the APP (representing 70% of the value of the award), we have made awards of between 50% and 100% of the maximum potential to the Executive Directors. The balance of the APP award is represented by performance against personal objectives set by the Remuneration Committee. As a result, we have made APP awards to the Executive Directors of between 64% and 119% of salary. Details of each Executive Director’s APP award are set out on page 70. This is the first year of the new policy for maximum APP payments, with the maximum being reduced from 150% of salary (for the 2013/14 awards) to 125%.

LTPP

2014 was the first year in which the maximum potential for the LTPP awarded during the year was increased in line with the new remuneration policy from 225% to 350% of salary for the Chief Executive and 200% to 300% of salary for the other Executive Directors. This is a three year plan and the performance outcomes will only be determined in July 2017. In 2014/15, Group RoE and value growth were both on target in relation to the 2014 LTPP parameters, with UK RoE around stretch, and US RoE below threshold.

The LTPP that vested during 2014/15 was that awarded in 2011. This included three performance measures: adjusted EPS; relative total shareholder return (TSR); and UK and US returns. The EPS measure vested at 31%, reflecting EPS growth just above the threshold target for this measure. The TSR measure vested at 98.3%, which reflects an annualised return to shareholders of 18.9% over the period. The UK and US returns measures are expected to vest at 100% and 25.9% respectively, reflecting strong operational performance in the UK, including the first two years of RIIO, and the impact of rate base growth and higher winter related costs in the US. As a result, the 2011 LTPP vested at between 46% and 66% for the Executive Directors. Details of each Executive Director’s vested LTPP are set out on pages 70 and 71.

Future targets

Details of future targets and historical performance are disclosed each year in respect of the LTPP. Details of historical performance against targets are disclosed each year in respect of the APP. We provide these details on pages 70 to 72 and page 74. Taking account of this year’s performance, as well as the challenges

Performance metrics, weighting

and time period applicable

Pension for a new Executive Director will reflect whether they are internally promoted or externally appointed.

If internally promoted:

● retention of existing DB benefits without enhancement, except for capping of pensionable pay increases following promotion to Board; or

● retention of existing UK DC benefits or equivalent cash in lieu; or

● retention of existing US DC benefits plus 401(k) plan match, provided through 401(k) plan and non-qualified plans.

If externally appointed:

● UK DC benefits or equivalent cash in lieu; or

● US DC benefits plus 401(k) plan match.

Andrew Bonfield, John Pettigrew and Dean Seavers are treated in line with the above policy.

Steve Holliday and Nick Winser are provided with final salary pension benefits. For service prior to 1 April 2013, pensionable pay is normally the base salary in the 12 months prior to leaving the Company. For service from 1 April 2013 increases to pensionable pay are capped at the lower of 3% or the increase in inflation. The pension scheme rules allow for indexed prior salaries to be used for all members. They participate in the unfunded scheme in respect of benefits in excess of the Lifetime Allowance.

Tom King participated in a qualified pension plan and in an Executive Supplemental Retirement Plan. These plans were non-contributory, cash balance and final average pay plans. Tom’s benefits included compensation to buy out entitlements from his former employer that were lost on recruitment to National Grid.

In line with market practice, pensionable pay for UK-based Executive Directors includes salary only and for US-based Executive Directors it includes salary and APP award.

UK DB: a maximum pension on retirement, at age 60, of two thirds final capped pensionable pay or up to one thirtieth accrual. On death in service, a lump sum of four times pensionable pay and a two thirds dependant’s pension is provided.

UK DC: annual contributions of 30% of salary. Life assurance provision of four times pensionable salary and a spouse’s pension equal to one third of the Director’s salary are provided on death in service.

US DB: an Executive Supplemental Retirement Plan provides for an unreduced pension benefit at age 62 (at age 55 in Tom King’s case). For retirements at age 62 with 35 years of service, the pension benefit would be approximately two thirds of pensionable pay. Upon death in service, the spouse would receive 50% of the pension benefit (100% if the participant died while an active employee after the age of 55).

US DC: 9% of base salary plus APP with additional 401(k) plan match of up to 4%.

and strategic business targets and the delivery of annual individual objectives.

Operation

Maximum levels

Performance metrics, weighting

and time period applicable

Performance metrics and targets are agreed at the start of each financial year. Performance metrics are aligned with strategic business priorities. Targets are set with reference to the budget. Awards are paid in June.

For APP awards made in 2013/14, 50% of any award was deferred into shares in the Deferred Share Plan (DSP). The DSP has no performance conditions and vests after three years, subject to continued employment. These shares are subject to forfeiture for leavers in certain circumstances.

The DSP has been discontinued for APP awards made in respect of years from 2014/15. Instead 50% of awards are paid in shares, which (after any sales to pay tax) must be retained until the shareholding requirement is met, and in any event for two years after receipt.

Awards are subject to clawback and malus provisions.

The maximum award is 125% of salary.

A significant majority of the APP is based on performance against corporate financial measures, with the remainder based on performance against individual objectives. Individual objectives are role specific.

The Committee may use its discretion to set measures that it considers appropriate in each financial year and reduce the amount payable, taking account of significant safety or customer service standard incidents, environmental and governance issues.

The payout levels at threshold, target and stretch performance levels are 0%, 50% and 100% respectively.

Awards of shares may be granted each year, with vesting subject to long-term performance conditions.

The performance metrics have been chosen as the Committee believes they reflect the creation of long-term value within the business. Targets are set each year with reference to the business plan.

Awards are subject to clawback and malus provisions. Notwithstanding the level of award achieved against the performance conditions, the Committee may use its discretion to reduce the amount vesting, and in particular will take account of compliance with the dividend policy.

The maximum award for the CEO is 350% of salary and it is 300% of salary for the other Executive Directors.

For awards made between 2011 and 2013, the maximum award for the CEO was 225% of salary and 200% for the other Executive Directors.

For awards between 2011 and 2013 the performance measures and weightings were:

● adjusted EPS (50%) measured over three years;

● TSR relative to the FTSE 100 (25%) measured over three years; and

● UK or US RoE relative to allowed regulatory returns (25%) measured over four years.

From 2014, the performance measures are:

● value growth and Group RoE (for the CEO and Finance Director); and

● value growth, Group RoE and UK or US RoE (for the UK and US Executive Directors respectively).

		Shareholding requirement The requirement of Executive Directors to build up and hold a relatively high value of National Grid shares ensures they share a significant level of risk with shareholders and their interests are aligned. From 2014/15, Executive Directors are required to build up and retain shares in the Company. The level of holding required is 500% of salary for the CEO and 400% of salary for the other Executive Directors. Unless the shareholding requirement is met, Executive Directors will not be permitted to sell shares, other than to pay tax or in exceptional circumstances.						The Company includes in its annual employee opinion survey questions on the appropriateness of the pay arrangements within the Company. It does not specifically invite employees to comment on the Directors’ remuneration policy but any comments made by employees are noted. Policy on recruitment remuneration Salaries for new Executive Directors appointed to the Board will be set in accordance with the terms of the approved remuneration policy in force at the time of appointment, and in particular will take account of the appointee’s skills and experience as well as the scope and market rate for the role. Where appropriate, salaries may be set below market level initially, with the Committee retaining discretion to award increases in salary in excess of those of the wider workforce and inflation to bring salary to a market level over time, where this is justified by individual and Company performance. Benefits consistent with those offered to other Executive Directors under the approved remuneration policy in force at the time of appointment will be offered, taking account of local market practice. The Committee may also agree that the Company will meet certain costs associated with the recruitment, for example legal fees, and the Committee may agree to meet certain relocation expenses or provide tax equalisation as appropriate. Pensions for new Executive Directors appointed to the Board will be set in accordance with the terms of the approved remuneration policy in force at the time of appointment. Ongoing incentive pay (APP and LTPP) for new Executive Directors will be in accordance with the approved remuneration policy in force at the time of appointment. This means the maximum APP award in any year would be 125% of salary and the maximum LTPP award would be 300% of salary (350% of salary for a new CEO). For an externally appointed Executive Director, the Company may offer additional cash or share-based payments that it considers necessary to buy out current entitlements from the former employer that will be lost on recruitment to National Grid. Any such arrangements would reflect the delivery mechanisms, time horizons and levels of conditionality of the remuneration lost. In order to facilitate buy-out arrangements as described above, existing incentive arrangements will be used to the extent possible, although awards may also be granted outside of these shareholder-approved schemes if necessary and as permitted under the Listing Rules. For an internally appointed Executive Director, any outstanding variable pay element awarded in respect of the prior role will continue on its original terms. Fees for a new Chairman or Non-executive Director will be set in line with the approved policy in force at the time of appointment.
		Differences in remuneration policy for all employees The remuneration policy for the Executive Directors is designed with regard to the policy for employees across the Company as a whole. However, there are some differences in the structure of remuneration policy for the senior executives. In general, these differences arise from the development of remuneration arrangements that are market competitive for our various employee categories. They also reflect the fact that, in the case of the Executive Directors, a greater emphasis tends to be placed on performance-related pay in the market, in particular long-term performance-related pay. All employees are entitled to base salary, benefits and pension. Many employees are eligible for an APP award based on Company and/or individual performance. Eligibility and the maximum opportunity available is based on market practice for the employee’s job band. In addition, around 350 senior management employees are eligible to participate in the LTPP. The Company has a number of all-employee share plans that provide employees with the opportunity to become, and to think like, a shareholder. These plans include Sharesave and the SIP in the UK and the 401(k) and 423(b) plans in the US. Further information is provided on page 62. Consideration of remuneration policy elsewhere in the Company In setting the remuneration policy, the Committee considers the remuneration packages offered to employees across the Company. As a point of principle, salaries, benefits, pensions and other elements of remuneration are benchmarked regularly to ensure they remain competitive in the markets in which we operate. In undertaking such benchmarking, our aim is to be at mid-market level for all job bands, including those subject to union negotiation. As would be expected, we have differences in pay and benefits across the business which reflect individual responsibility and there are elements of remuneration policy which apply to all, for example, flexible benefits and share plans. When considering annual salary increases, the Committee reviews the proposals for salary increases for the employee population generally, as it does for any other changes to remuneration policy being considered. This will include a report on the status of negotiations with any trade union represented employees.


66


Service contracts and policy on payment for loss of office In line with our policy, all Executive Directors have service contracts which are terminable by either party with 12 months’ notice. The contracts contain provisions for payment in lieu of notice, at the sole and absolute discretion of the Company. Such payments are limited to payment of salary only for the remainder of the notice period. In the UK such payments would be phased on a monthly basis, over a period no greater than 12 months, and the Executive Director would be expected to mitigate any losses where employment is taken up during the notice period. In the US, for tax purposes the policy is to make any payment in lieu of notice as soon as reasonably practicable, and in any event within two and a half months of the later of 31 December and 31 March immediately following the notice date. In the event of a UK Director being made redundant, statutory compensation would apply and the relevant pension plan rules may result in the early payment of an unreduced pension. On termination of employment, no APP award would generally be payable and any DSP awards would generally lapse. However, the Committee has the discretion to deem an individual to be a ‘good leaver’, in which case an APP award would be payable on the termination date, based on performance during the financial year up to termination, and DSP awards would vest on the termination date. Examples of circumstances in which a Director would be treated as a ‘good leaver’ include redundancy, retirement, illness, injury, disability and death. Any APP award would be prorated and would be subject to performance achieved against the objectives for that year. On termination of employment, outstanding awards under the share plans will be treated in accordance with the relevant plan rules approved by shareholders. Share awards would normally lapse. ‘Good leaver’ provisions apply at the Committee’s discretion and in specified circumstances, including redundancy, retirement, illness, injury, disability and death, where awards will be released to the departing Executive Director or, in the case of death, to their estate. Long-term share plan awards held by ‘good leavers’ may vest subject to performance measured at the normal vesting date and are prorated. Such awards would vest at the same time as for other participants. The Chairman’s appointment is subject to six months’ notice by either party; for the other Non-executive Directors, notice is one month. No compensation is payable to Non-executive Directors if required to stand down. Copies of Directors’ service contracts and letters of appointment are available to view at the Company’s registered office.	Dates of Directors’ service contracts/letters of appointment

		1. ‘Fixed pay’ for Andrew Bonfield, Steve Holliday and John Pettigrew consists of salary, pension and benefits in kind as provided under the remuneration policy. ‘Fixed pay’ for Dean Seavers consists of salary, the part of his pension that is aligned with salary (see footnote 4 below) and benefits in kind as provided under the remuneration policy.
		2. Salary is that to be paid in 2015/16, taking account of the increases that will be effective from 1 June 2015 shown on page 74.
		3. Benefits in kind are as shown in the single total figure of remuneration table for 2014/15 on page 69, except for Dean Seavers for whom benefits in kind are assumed to be $37,000.
		4. Pension is as shown in the single total figure of remuneration table for 2014/15 on page 69, except for Andrew Bonfield for whom pension is shown as 30% of salary and Dean Seavers, for whom pension is shown as 13% of salary plus 13% of APP. This is made up of a 9% Core Plan contribution and a 4% Company match to his 401(k) plan. The element of Dean’s pension that is aligned with salary is shown within ‘Fixed pay’ and the element of his pension that is aligned with APP is shown within ‘APP’. 5. APP calculations are based on 125% of salary for the period 1 April 2015 to 31 March 2016. For Dean Seavers, APP also includes the part of his pension that is aligned with APP (see footnote 4 above). 6. LTPP calculations are based on awards with a face value at grant of 350% of 1 June 2015 salary for Steve Holliday and 300% of 1 June 2015 salary for all other Executive Directors. They, therefore, exclude future share price movement. 7. LTPP and APP payout is 50% for on target performance and the maximum is 100% for achieving stretch performance. 8. Dean Seaver’s remuneration opportunity has been converted at $1.58:£1.
		Statement of consideration of shareholder views The Committee considers all feedback received from shareholders throughout the year. While the Committee understands that not all shareholders’ views will be the same, we consult with our larger shareholders on a regular basis to understand their expectations with regard to executive remuneration issues and any changes in shareholder views in this regard. In 2013/14, we consulted larger shareholders on the proposed changes to remuneration policy. Shareholders were supportive of the direction of change proposed, particularly increasing holding periods for awards and retention thresholds. Several responses suggested a number of small changes and where possible the Committee reflected these changes in the proposals that were approved at the 2014 AGM.

1. Base salaries were last increased on 1 June 2014. At this time Andrew Bonfield, Steve Holliday and Tom King all received salary increases of 2.5%, in line with the salary increase given to other employees of the Company. John Pettigrew joined the Board on 1 April 2014 and was not given a salary increase at 1 June 2014. Nick Winser was not given a salary increase at 1 June 2014, as he was stepping down from the Board at the 2014 AGM. Tom King’s annual salary was converted at $1.58:£1 in 2014/15 and $1.62:£1 in 2013/14.

2. Benefits in kind include private medical insurance, life assurance, either a fully expensed car or a cash alternative to a car and the use of a driver when required. For Andrew Bonfield, Steve Holliday and John Pettigrew, it also includes the benefits of Sharesave options granted during the year. For Andrew Bonfield, a cash allowance in lieu of pension contributions is included within pension rather than benefits in kind.

3. The APP value for 2013/14 is the full award before the 50% mandatory deferral into the DSP.

4. A portion of the 2011 LTPP award vested in July 2014, with the remainder due to vest in July 2015. The above value is based on the share price (855 pence) on the vesting date (1 July 2014) for that portion that vested on 1 July 2014, and the average share price over the three months from 1 January 2015 to 31 March 2015 (899 pence) for that portion due to vest on 1 July 2015. In the prior year the 2010 PSP award vested and entered a retention period which ended in June 2014. The above valuation is based on the share price (744 pence) on the vesting date (1 July 2013).

5. The pension figure for Tom King is based on his accrued benefit at date of leaving. Tom is required to take his benefit from age 55 (2016) and, under the provisions of the plan, his pension will be reduced for early payment.

6. John Pettigrew was appointed to the Board on 1 April 2014, and hence his single total figure of remuneration for 2013/14 was £nil.

7. Nick Winser stood down from the Board on 28 July 2014. His salary, benefits in kind and APP for 2014/15 shown above are prorated to reflect qualifying service between 1 April and 28 July 2014 during which time Nick was a member of the Board. The 2011 LTPP for 2014/15 shown above is not prorated, as this relates to the three-year period ended 30 June 2014, prior to Nick standing down from the Board. The 2011 LTPP only includes the EPS and TSR portion that vested during the year. The RoE portion is not included as Nick was not a Director at the end of the year. The RoE portion will be disclosed in the 2015/16 Remuneration Report under payments to past Directors. The pension for 2014/15 shown above represents pension earned by Nick over the full year to 31 March 2015, as required by BIS disclosure regulations.

2014/15 LTPP performance (audited information)

The LTPP value included in the 2014/15 single total figure relates to vesting of the conditional LTPP award granted in 2011. Part of the award – that dependent on performance over the three years ending 31 March 2014 for the EPS measure (50% weighting) and over the three years ending 30 June 2014 for the TSR measure (25% weighting) – vested on 1 July 2014. The remaining 25% weighting of the 2011 LTPP relates to the RoE measure. This is made up of the UK RoE measure for the UK Executive Directors, the US RoE measure for the US Executive Director and both the UK RoE measure and the US RoE measure in equal weightings for the CEO and Group Finance Director. The UK RoE measure is measured over the four years ending 31 March 2015 and the US RoE measure is measured over the four years ending 31 December 2014. However, the award does not vest until four years after the grant date, i.e. until 1 July 2015. The performance achieved against the performance targets, including the expected vesting percentage for the RoE measures, was:

1.	The UK-based Executive Directors participate in FPS, a salary sacrifice arrangement. Under FPS, the individual’s salary is reduced by an amount equal to the employee pension contribution that would have been paid into the scheme. An equivalent contribution is paid into the scheme by the employer.
2.	For Steve Holliday, in addition to the accrued DB-type pension at 31 March 2015 above, there is an accrued lump sum entitlement of £127,000 as at 31 March 2015. The increase to the accumulated lump sum, net of inflation, was £1,000 in the year to 31 March 2015.
3.	For Nick Winser, in addition to the accrued DB-type pension at 31 March 2015 above, there is an accrued lump sum entitlement of £316,000 as at 31 March 2015. The accumulated lump sum reduced by £6,000 in the year to 31 March 2015, after allowing for inflation.
4.	For John Pettigrew, in addition to the accrued DB-type pension at 31 March 2015 above, there is an accrued lump sum entitlement of £428,000 as at 31 March 2015. The increase to the accumulated lump sum net of inflation was £63,000 in the year to 31 March 2015.
5.	For Tom King, the exchange rate as at 31 March 2015 was $1.49:£1 and as at 31 March 2014 was $1.67:£1. Through Tom King’s participation in the 401(k) plan in the US (a DC arrangement) the Company made contributions worth £8,076.
6.	For Steve Holliday, John Pettigrew and Nick Winser, the increase in accrued DB-type pension over the year shown above is net of inflation, as UK pensions in payment or deferment increase in line with inflation. For Tom King, the increase in accrued DB-type pension over the year shown above does not allow for inflation, as US pensions in payment or deferment do not increase in line with inflation.
7.	In accordance with BIS methodology, the pension benefit for Andrew Bonfield is calculated as the aggregate of contributions made to a DC-type pension plan (£nil) and cash in lieu of contributions to a DC-type pension plan (£218,000). In accordance with BIS disclosure regulations, the pension benefit for Steve Holliday, Tom King, John Pettigrew and Nick Winser is calculated as the increase in accrued DB-type pension over the year shown above multiplied by 20 plus the increase or less the decrease in the lump sum shown above, less the reduction in salary due to FPS plus total contributions made to DC-type pension plans. Each element is calculated separately and rounded to produce the numbers in the table above.
8.	There are no additional benefits in the event of early retirement.

Performance graph and table						Total shareholder return
This chart shows National Grid plc’s six year annual total shareholder return (TSR) performance against the FTSE 100 Index since 31 March 2009. The FTSE 100 Index has been chosen because it is the widely recognised performance benchmark for large companies in the United Kingdom. Over the last four years, National Grid’s TSR has outperformed that of the FTSE 100 and underpins the pay shown for the Chief Executive in the table below, using current and previously published single total remuneration figures. The TSR level shown at 31 March each year is the average of the closing daily TSR levels for the 30 day period up to and including that date. It assumes dividends are reinvested.

Percentage change in CEO’s remuneration
The table below shows how the percentage change in the CEO’s salary, benefits and APP between 2013/14 and 2014/15 compares with the percentage change in the average of each of those components of remuneration for non-union employees in the UK. The Committee views this group as the most appropriate comparator group, as the CEO is UK-based and this group excludes employees represented by trade unions, whose pay and benefits are negotiated with each individual union.

1. The Taxable benefits figure for 2014/15 for Steve Holliday and for UK non-union employees includes the benefit of Sharesave options granted during the year which were not in the benefits total for 2013/14.

Statement of implementation of remuneration policy in 2015/16
The remuneration policy adopted at the 2014 AGM will continue to be implemented during 2015/16 as follows:
Salary
						From 1 June 2015		From 1 June 2014		Increase

Andrew Bonfield							£737,000		£729,800		0.99%
Steve Holliday							£1,035,000		£1,025,000		0.98%
John Pettigrew							£508,250		£475,000		7%
Dean Seavers (from 1 April 2015)							$1,000,000		$1,000,000		0%

There will be no change to the implementation of the remuneration policy for 2015/16. Salary increases will normally be in line with the increase awarded to other employees in the UK and US, unless there is a change in role or responsibility. In line with the policy on recruitment remuneration, salaries for new directors may be set below market level initially and aligned to market level over time (provided the increase is merited by the individual’s contribution and performance).

Advisors to the Remuneration Committee
The Committee received advice during 2014/15 from independent remuneration consultants New Bridge Street (NBS), a trading name of Aon Hewitt Ltd (part of Aon plc). NBS were selected as advisors by the Committee from 1 August 2013 following a competitive tendering process.
Work undertaken by NBS included updating the Committee on trends in compensation and governance matters and advising the Committee in connection with benchmarking of the total reward packages for the Executive Directors and other senior employees. NBS are a member of the Remuneration Consultants Group and have signed up to that group’s Code of Conduct. The Committee is satisfied that any potential conflicts were appropriately managed. NBS does not provide any other advice or services to the Company. In the year to 31 March 2015 the Committee paid a total of £88,890 to NBS, with fees being charged on a time incurred basis.
The Committee also received specialist advice from the following organisations:
● Alithos Limited: provision of TSR calculations for the LTPP (£18,750 paid in 2014/15);
● Linklaters LLP: advice relating to share schemes and to Directors’ service contracts as well as providing other legal advice to the Company (£82,330 paid in 2014/15); and
● Towers Watson: advice relating to the benchmarking of the total reward packages for the Executive Directors and other senior employees (£74,450 paid in 2014/15).
The Committee reviews the objectivity and independence of the advice it receives from its advisors each year. It is satisfied that they all provided credible and professional advice.
The Committee considers the views of the Chairman on the performance and remuneration of the CEO; and of the CEO on the performance and remuneration of the other members of the Executive Committee. The Committee is also supported by the Group General Counsel & Company Secretary who acts as Secretary to the Committee, the Group HR Director, the Global Head of Reward and the Global Head of Pensions. No other advisors have provided significant services to the Committee in the year.

Introduction to the financial statements


		We have continued to develop our presentational format to provide shareholders and users of these financial statements with additional information and guidance, and to make them easier to understand.
		Throughout these financial statements we have provided plain English explanations of the disclosures and why they are important to the understanding of our financial performance and position. In places we have also highlighted ‘Our strategy in action’, drawing out the key elements of our business model (set out in the Strategic Report on pages 12 to 13), and showing how the disclosures reflect this strategy.
		Audit opinions
		We have two audit opinions on our financial statements, reflecting our dual listing on the London Stock Exchange and the New York Stock Exchange. Due to the different reporting requirements for each listing, our auditors are required to confirm compliance with each set of standards in a prescribed format. The audit opinion as required under our UK listing (starting on page 79) continues to provide more detail as to how our auditors have planned and completed their audit, as well as their views on significant matters they have noted and that were discussed by the Audit Committee.
		Notes
		Notes to the financial statements provide additional information required by statute, accounting standards or other regulations to assist in a more detailed understanding of the primary financial statements. In many notes we have included an accounting policy that describes how the transactions or balance in that note have been measured, recognised and disclosed. The basis of preparation section (note 1) provides details of accounting policies that apply to transactions and balances in general. There are also additional specific disclosure requirements due to our US listing which are included in the notes.


		Unaudited commentary We have presented with the financial statements certain analysis as part of the Strategic Report of our Annual Report. This approach provides a clearer narrative, a logical flow of information and reduces duplication. We have created a combined financial review, including a commentary on items within the primary statements, on pages 86 to 93. Unless otherwise indicated, all analysis provided in the financial statements is on a statutory IFRS basis. All information in ruled boxes styled in the same manner as this one does not form part of the audited financial statements. This has been further highlighted by including the word ‘unaudited’ at the start of each box header. Unaudited commentary boxes appear on pages 87 to 89, 91, 93, 99 to 100, 110, 112 and 125.

		Financial Statements
		Statement of Directors’ responsibilities


		The Directors are responsible for preparing the Annual Report and Accounts, including the consolidated financial statements and the Company financial statements, the Directors’ Report, including the Remuneration Report and the Strategic Report, in accordance with applicable law and regulations. Company law requires the Directors to prepare financial statements for each financial year. Under that law the Directors have prepared the consolidated financial statements in accordance with International Financial Reporting Standards (IFRS) as adopted by the European Union, and the Company financial statements and the Remuneration Report in accordance with applicable law and United Kingdom Accounting Standards (United Kingdom Generally Accepted Accounting Practice, UK GAAP). In preparing the consolidated financial statements, the Directors have also elected to comply with IFRS, issued by the International Accounting Standards Board (IASB). Under company law the Directors must not approve the financial statements unless they are satisfied that they give a true and fair view of the state of affairs of the Company on a consolidated and individual basis and of the profit or loss of the Company on a consolidated basis for that period. In preparing these financial statements, the Directors are required to: ● select suitable accounting policies and then apply them consistently; ● make judgements and estimates that are reasonable and prudent; ● state that the consolidated financial statements comply with IFRS as issued by the IASB and IFRS adopted by the European Union and, with regard to the Company financial statements, that applicable UK Accounting Standards have been followed, subject to any material departures disclosed and explained in the financial statements; and ● prepare the consolidated financial statements and Company financial statements on a going concern basis unless it is inappropriate to presume that the Company, on a consolidated and individual basis, will continue in business, in which case there should be supporting assumptions or qualifications as necessary.				The Directors are responsible for keeping adequate accounting records that are sufficient to show and explain the Company’s transactions and disclose with reasonable accuracy at any time the financial position of the Company on a consolidated and individual basis, and to enable them to ensure that the consolidated financial statements comply with the Companies Act 2006 and Article 4 of the IAS Regulation and the Company financial statements and the Remuneration Report comply with the Companies Act 2006. They are also responsible for safeguarding the assets of the Company and its subsidiaries and hence for taking reasonable steps for the prevention and detection of fraud and other irregularities. The Directors are responsible for the maintenance and integrity of the Company’s website. Legislation in the United Kingdom governing the preparation and dissemination of financial statements may differ from legislation in other jurisdictions. Having made the requisite enquiries, so far as the Directors in office at the date of the approval of this Report are aware, there is no relevant audit information of which the auditors are unaware and each Director has taken all reasonable steps to make themselves aware of any relevant audit information and to establish that the auditors are aware of that information.
						Each of the Directors, whose names and functions are listed on page 43, confirms that:
						● to the best of their knowledge, the consolidated financial statements and the Company financial statements, which have been prepared in accordance with IFRS as issued by the IASB and IFRS as adopted by the European Union and UK GAAP respectively, give a true and fair view of the assets, liabilities, financial position and profit of the Company on a consolidated and individual basis; ● to the best of their knowledge, the Strategic Report contained in the Annual Report and Accounts includes a fair review of the development and performance of the business and the position of the Company on a consolidated and individual basis, together with a description of the principal risks and uncertainties that it faces; and ● they consider that the Annual Report and Accounts, taken as a whole, is fair, balanced and understandable and provides the information necessary for shareholders to assess the Company’s position and performance, business model and strategy.

		Report of Independent Registered Public Accounting Firm
		to the Board of Directors and Shareholders of National Grid plc

Audit opinion for Form 20-F

In our opinion, the accompanying consolidated statement of financial position and the related consolidated income statement, consolidated statement of comprehensive income, consolidated cash flow statement and consolidated statement of changes in equity, present fairly, in all material respects, the financial position of National Grid plc and its subsidiaries at 31 March 2015 and 31 March 2014, and the results of their operations and their cash flows for each of the three years in the period ended 31 March 2015 in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board and in conformity with International Financial Reporting Standards as adopted by the European Union.

Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of 31 March 2015, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the Additional Information section appearing on page 173 of the 2015 Annual Report and Accounts.

Our responsibility is to express opinions on these financial statements and on the Company’s internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorisations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorised acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Unaudited commentary on the consolidated income statement

The consolidated income statement shows all revenue earned and costs incurred in the year, with the difference being the overall profit for the year.

Revenue

Revenue for the year ended 31 March 2015 increased by £392m to £15,201m. This increase was driven by higher revenues in our UK Electricity Transmission business, reflecting increases in allowed Transmission Owner revenues, and higher core allowances and pass-through costs in UK Gas Transmission. Revenues in our UK Gas Distribution business were slightly lower as a result of changes in allowed revenues for replacement expenditure (repex). Our US Regulated businesses revenues were also lower, as a result of the end of the LIPA Management Services Agreement (MSA) last year, partially offset by revenue increases from existing rate plans, including capex trackers, together with additional income from gas customer growth and the impact of the strengthening US dollar.

Operating costs

Operating costs for the year ended 31 March 2015 of £11,421m were £347m higher than the prior year. This increase in costs included a £154m year on year impact of changes in exceptional items, remeasurements and stranded cost recoveries, which is discussed below. Excluding exceptional items, remeasurements and stranded cost recoveries, operating costs were £193m higher, principally due to: increases in controllable costs, including the impact of inflation and additional costs incurred in the US to improve data quality and bring regulatory filings up to date; higher US bad debt costs following last year’s exceptionally cold winter; and higher depreciation and amortisation as a result of continued investment programmes. These cost increases were partly offset by a reduction in spend on US financial systems implementation and stabilisation upgrades, with the project completing in the first half of this year.

Net finance costs

For the year ended 31 March 2015, net finance costs before exceptional items and remeasurements were £75m lower than 2013/14 at £1,033m, mainly as a result of lower average gross debt through the year, lower RPI in the UK and refinancing debt at lower rates.

Tax

The tax charge on profit before exceptional items, remeasurements and stranded cost recoveries was £114m higher than 2013/14. This was mainly due to higher profits before tax and the non-recurrence of one-off items that benefited the prior year.

Exceptional items, remeasurements and stranded cost recoveries

Operating profit for the year ended 31 March 2015 included an £83m loss (2013/14: £16m gain) on remeasurement of commodity contracts. The year ended 31 March 2014 also included a net £55m gain on exceptional items, including a net gain on the LIPA MSA transition in the US of £254m; restructuring costs of £136m, primarily in the UK as we reorganised certain parts of our business to deliver under the new RIIO price controls; and a £79m provision for the demolition of UK gas holders that are no longer required.

Finance costs for the year ended 31 March 2015 included exceptional debt redemption costs of £131m and a loss of £34m on financial remeasurements, relating to net losses on derivative financial instruments.

Exceptional tax for 2014/15 of £78m primarily represents tax credits on the exceptional items and remeasurements described above.

Adjusted earnings and EPS

The following chart shows the five year trend in adjusted profit attributable to equity shareholders of the parent (adjusted earnings) and adjusted earnings per share. See page 186 for a reconciliation of adjusted basic EPS to EPS.

Adjusted earnings and adjusted EPS¹

LOGO

1. Adjusted earnings and adjusted EPS are attributable to equity shareholders of the parent.

The above earnings performance translated into adjusted EPS growth in 2014/15 of 4.6p (9%).

In accordance with IAS 33, all earnings per share and adjusted earnings per share amounts for comparative periods have been restated for shares issued via scrip dividends.

Exchange rates

Our financial results are reported in sterling. Transactions for our US operations are denominated in dollars, so the related amounts that are reported in sterling depend on the dollar to sterling exchange rate.

If 2013/14 results had been translated at 2014/15 exchange rates, revenue, adjusted operating profit and operating profit reported in sterling would have been £212m, £25m and £32m higher respectively.

Unaudited commentary on consolidated statement of comprehensive income

The consolidated statement of comprehensive income records certain items as prescribed by the accounting rules. For us, the majority of the income or expense included here relates to movements in actuarial assumptions on pension schemes and the associated tax impact. These items are not part of profit for the year, yet are important to allow the reader to gain a more comprehensive picture of our performance as a whole.

Remeasurements of net retirement benefit obligations

We had a net loss after tax of £472m (2013/14: net gain of £313m) on our pension and other post-retirement benefit schemes which is due to changes in key assumptions made in the valuation calculation of pension liabilities and differences between the expected and actual pension asset returns.

Exchange adjustments

Adjustments are made when we translate the results and net assets of our companies operating outside the UK, as well as debt we have issued in foreign currencies. The net movement for the year resulted in a gain of £175m (2013/14: £158m loss).

Net (losses)/gains in respect of cash flow hedges

The value of derivatives held to hedge cash flows is impacted by changes in expected interest rates and exchange rates. The net loss for the year was £154m (2013/14: £63m gain).

Unaudited commentary on consolidated statement of financial position

The consolidated statement of financial position shows all of the Group’s assets and liabilities at the year end. As a capital-intensive business, we have significant amounts of physical assets and corresponding borrowings.

Goodwill and other intangible assets

Goodwill and intangibles increased by £684m to £5,947m as at 31 March 2015. This increase primarily relates to foreign exchange movements of £602m and software additions of £207m, partially offset by software amortisation of £121m.

Property, plant and equipment

Property, plant and equipment increased by £3,544m to £40,723m as at 31 March 2015. This was principally due to capital expenditure of £3,263m on the renewal and extension of our regulated networks and foreign exchange movements of £1,703m, offset by depreciation of £1,361m in the year. See page 22 for further details of our capital expenditure.

Investments and other non-current assets

Investments in joint ventures and associates, financial and other investments and other non-current assets have increased by £6m to £728m. This is primarily due to a decrease in investments in joint ventures of £33m, which includes dividends received of £79m, partially offset by our share of post-tax results for the year of £46m, more than offset by an increase in available-for-sale investments of £46m.

Inventories and current intangible assets, and trade and other receivables

Inventories and current intangible assets, and trade and other receivables have increased by £53m to £3,176m as at 31 March 2015. This is due to an increase in inventories and current intangible assets of £72m, offset by a net decrease in trade and other receivables of £19m. The £19m decrease consists of an increase in foreign exchange of £211m due to the stronger US dollar against sterling and a decrease in the underlying balances of £229m, reflecting collection of large prior year balances, including LIPA MSA and Superstorm Sandy re-insurance receivables.

Trade and other payables

Trade and other payables have increased by £261m to £3,292m, primarily due to foreign exchange movements of £161m and an increase in VAT liability following a change in regulations on wholesale gas and electricity trading.

Current tax balances

Current tax balances have decreased by £33m to £124m as at 31 March 2015. This is primarily due to the tax payments made in 2014/15 being only partially offset by a smaller current year tax charge.

Deferred tax balances

Deferred tax balances have increased by £215m to £4,297m as at 31 March 2015. This was primarily due to the impact of the £299m deferred tax credit on actuarial losses (a £172m tax charge in 2013/14) being offset by the impact of the reduction in the UK statutory tax rate, foreign exchange movements of £203m and the reduction in prior year charges.

Provisions and other non-current liabilities

Provisions (both current and non-current) and other non-current liabilities increased by £168m to £3,654m as at 31 March 2015.

Total provisions increased by £90m in the year. The underlying movements include additions of £105m relating to an increase to the provision for the estimated environmental restoration and remediation costs for a number of sites and other provision increases of £57m, together with foreign exchange movements of £133m, offset by utilisation of £209m in relation to all classes of provisions.

Net debt

Net debt is the aggregate of cash and cash equivalents, current financial and other investments, borrowings, and derivative financial assets and liabilities. See further analysis with the consolidated cash flow statement on page 92.

Net pension and other post-retirement obligations

A summary of the total UK and US assets and liabilities and the overall net IAS 19 (revised) accounting deficit is shown below:

Plan liabilities		(20,125	)		(9,541	)		(29,666)

		(672	)		(2,586	)		(3,258)

The principal movements in net obligations during the year include net actuarial losses of £771m and employer contributions of £508m. Net actuarial losses include actuarial losses on plan liabilities of £2,746m arising as a consequence of increases in the UK real discount rate and the nominal discount rate in the US. This is partially offset by actuarial gains of £2,154m arising on plan assets.

Further information on our pension and other post-retirement obligations can be found in notes 22 and 29 to the consolidated financial statements.

Off balance sheet items

There were no significant off balance sheet items other than the contractual obligations shown in note 30(b) to the consolidated financial statements, and the commitments and contingencies discussed in note 27.

Through the ordinary course of our operations, we are party to various litigation, claims and investigations. We do not expect the ultimate resolution of any of these proceedings to have a material adverse effect on our results of operations, cash flows or financial position.

Unaudited commentary on the consolidated cash flow statement

The consolidated cash flow statement shows how the cash balance has moved during the year. Cash inflows and outflows are presented to allow users to understand how they relate to the day-to-day operations of the business (Operating activities); the money that has been spent or earned on assets in the year, including acquisitions of physical assets or other businesses (Investing activities); and the cash raised from debt or share issues and other loan borrowings or repayments (Financing activities).

Cash generated from operations

Cash generated from operations £m

LOGO

Cash flows from our operations are largely stable when viewed over the longer term. Our electricity and gas transmission and distribution operations in the UK are subject to multi-year rate agreements with regulators. In the UK, we have largely stable inter-year cash flows. However, in the US our short-term cash flows are dependent on the price of gas and electricity and the timing of customer payments. The regulatory mechanisms for recovering costs from customers can result in significant cash flow swings from year to year. Changes in volumes in the US, for example as a consequence of abnormally mild or extreme weather can affect cash flows, particularly in the winter months.

For the year ended 31 March 2015, cash flow from operations increased by £931m to £5,350m.

Changes in working capital improved by £360m over the prior year, principally in the US (£441m) due to the collection of high winter 2014 billings and other settlements including Hurricane Sandy re-insurance claims and LIPA receipts. Cash outflows relating to exceptional items were £133m lower, as the prior year included reorganisation costs in the UK and LIPA MSA transition costs in the US.

Net capital expenditure

Net capital expenditure in the year of £3,274m was £155m higher than the prior year. This was a result of higher spend in our US regulated businesses, reflecting a record year of investment, partially offset by lower spend in our UK regulated businesses.

Net interest paid

Net interest paid and exceptional finance costs in 2014/15 were £941m, £75m higher than 2013/14 due to £152m debt redemption cash outflows.

Tax paid

Tax paid in the year to 31 March 2015 was £343m, £57m lower than prior year. This reflected repayments received in the US during the period.

Dividends paid

Dividends paid in the year ended 31 March 2015 amounted to £1,271m. This was £212m higher than 2013/14, reflecting the increase in the final dividend for the year ended 31 March 2014 paid in August 2014, together with a lower average scrip dividend take-up in the year.

Other cash movements

Other cash flows principally arise from dividends from joint ventures and movements in treasury shares, including the cost of repurchasing shares as part of the share buyback programme (£338m).

Non-cash movements

The non-cash movements are predominantly due to the strengthening of the US dollar against sterling, resulting in movements in foreign exchange arising on net debt held in currencies other than sterling. In the year, the dollar strengthened from $1.67 at 31 March 2014 to $1.49 at 31 March 2015.

Other non-cash movements are from changes in fair values of financial assets and liabilities and interest accretions and accruals.

The 2014 and 2013 comparative financial information has also been prepared on this basis.
				The consolidated financial statements have been prepared on an historical cost basis, except for the recording of pension assets and liabilities, the revaluation of derivative financial instruments and certain commodity contracts and investments classified as available-for-sale.
				The consolidated financial statements have been prepared on a going concern basis. The going concern basis presumes that the Group has adequate resources to remain in operation, and that the Directors intend it to do so, for at least one year from the date the financial statements are signed. Further details of the Directors’ assessment are set out on page 54.
				These consolidated financial statements are presented in pounds sterling, which is also the functional currency of the Company.
				The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities and the reported amounts of revenue and expenses during the reporting period (see accounting policy C).
				A. Basis of consolidation
				The consolidated financial statements incorporate the financial statements of the Company and its subsidiaries, together with a share of the results, assets and liabilities of jointly controlled entities (joint ventures) and associates using the equity method of accounting, where the investment is carried at cost plus post-acquisition changes in the share of net assets of the joint venture or associate, less any provision for impairment.
				A subsidiary is defined as an entity controlled by the Company. Control is achieved where the Company has the power to affect the returns of an entity to which it is exposed or to which it has rights.
				Losses in excess of the consolidated interest in joint ventures and associates are not recognised, except where the Company or its subsidiaries have made a commitment to make good those losses.
				Where necessary, adjustments are made to bring the accounting policies used in the individual financial statements of the Company, subsidiaries, joint ventures and associates into line with those used by the Company in its consolidated financial statements under IFRS. Intercompany transactions are eliminated.
				The results of subsidiaries, joint ventures and associates acquired or disposed of during the year are included in the consolidated income statement from the effective date of acquisition or up to the effective date of disposal, as appropriate.
				Acquisitions are accounted for using the acquisition method, where the purchase price is allocated to the identifiable assets acquired and liabilities assumed on a fair value basis and the remainder recognised as goodwill.

		1. Basis of preparation and recent accounting developments continued
		B. Foreign currencies
		Transactions in currencies other than the functional currency of the Company or subsidiary concerned are recorded at the rates of exchange prevailing on the dates of the transactions. At each reporting date, monetary assets and liabilities that are denominated in foreign currencies are retranslated at closing exchange rates. Non-monetary assets are not retranslated unless they are carried at fair value.

		Gains and losses arising on the retranslation of monetary assets and liabilities are included in the income statement, except where the adoption of hedge accounting requires inclusion in other comprehensive income – note 15.

		On consolidation, the assets and liabilities of operations that have a functional currency different from the Company’s functional currency of pounds sterling, principally our US operations that have a functional currency of dollars, are translated at exchange rates prevailing at the reporting date. Income and expense items are translated at the average exchange rates for the period where these do not differ materially from rates at the date of the transaction. Exchange differences arising are classified as equity and transferred to the consolidated translation reserve.

		C. Areas of judgement and key sources of estimation uncertainty
		The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates. Information about such judgements and estimations is contained in the notes to the financial statements, and the key areas are summarised below.

		Areas of judgement that have the most significant effect on the amounts recognised in the financial statements are as follows:

		●		the categorisation of certain items as exceptional items and the definition of adjusted earnings – notes 4 and 7; and
		●		energy purchase contracts as being for normal purchase, sale or usage – note 27.

		IFRS provides certain options available within accounting standards. Choices we have made, and continue to make, include the following:

		●		Presentational formats: we use the nature of expense method for our income statement and aggregate our statement of financial position to net assets and total equity. In the income statement, we present subtotals of total operating profit, profit before tax and profit from continuing operations, together with additional subtotals excluding exceptional items, remeasurements and stranded cost recoveries. Exceptional items, remeasurements and stranded cost recoveries are presented separately on the face of the income statement.
		●		Customer contributions: contributions received prior to 1 July 2009 towards capital expenditure are recorded as deferred income and amortised in line with the depreciation on the associated asset.
		●		Financial instruments: we normally opt to apply hedge accounting in most circumstances where this is permitted. For net investment hedges, we have chosen to use the spot rate method, rather than the alternative forward rate method.

		Key sources of estimation uncertainty that have significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year are as follows:

		●		review of residual lives, carrying values and impairment charges for other intangible assets and property, plant and equipment – notes 10 and 11;
		●		estimation of liabilities for pensions and other post-retirement benefits – notes 22 and 29;
		●		valuation of financial instruments and derivatives – notes 15 and 30;
		●		revenue recognition and assessment of unbilled revenue – note 2; and
		●		environmental and decommissioning provisions – note 23.
		In order to illustrate the impact that changes in assumptions could have on our results and financial position, we have included sensitivity analysis in note 33.

		New IFRS accounting standards and interpretations adopted in 2014/15
		The following standards, interpretations and amendments, issued by the IASB and by the IFRS Interpretations Committee (IFRIC), are effective for the year ended 31 March 2015. None of the pronouncements has had a material impact on the Company’s consolidated results or assets and liabilities for the year ended 31 March 2015.

		●		IFRIC 21 ‘Levies’;
		●		amendments to IAS 32 ‘Financial Instruments: Presentation’ in respect of offsetting financial assets and financial liabilities;
		●		amendments to IFRS 10 ‘Consolidated Financial Statements’, IFRS 12 ‘Disclosure of Interests in Other Entities’ and IAS 27 ‘Separate Financial Statements’ in respect of investment entities;
		●		amendments to IAS 36 ‘Impairment of Assets’ in respect of recoverable amount disclosures for non-financial assets; and
		●		amendments to IAS 39 ‘Financial Instruments: Recognition and Measurement’, in respect of novation of derivatives and continuation of hedge accounting.

Notes to the consolidated financial statements

– analysis of items in the primary statements continued


		1. Basis of preparation and recent accounting developments continued
		New IFRS accounting standards and interpretations not yet adopted
		The Company enters into a significant number of transactions that fall within the scope of IFRS 9 ‘Financial Instruments’, effective for periods beginning after 1 January 2018. We are assessing the likely impact of this standard on the Company’s financial statements.

		IFRS 15 ‘Revenue from Contracts with Customers’ was issued by the IASB in May 2014. Subject to EU endorsement, it is effective for accounting periods beginning on or after 1 January 2017. The new standard provides enhanced detail on the principle of recognising revenue to reflect the transfer of goods and services to customers at a value which the Company expects to be entitled to receive.

		The Group has completed an initial impact assessment of the new standard by completing a survey of all businesses identifying the likely impact of IFRS 15. This was a tailored questionnaire based on the known impacts of the new standard on power and utility companies. Whilst no material differences were identified as part of the questionnaire process, further follow-up work will be required to determine the impact, if any, on certain revenue items including, but not limited to, variable consideration contracts, take or pay arrangements and performance obligations where multiple goods or services are provided in individual contracts.

		Other standards and interpretations or amendments thereto which have been issued, but are not yet effective, are not expected to have a material impact on the Company’s consolidated financial statements.
		2. Segmental analysis
		This note sets out the financial performance for the year split into the different parts of the business (operating segments). We monitor and manage the performance of these operating segments on a day-to-day basis.
		Our strategy in action
		We own a portfolio of businesses that range from businesses with high levels of investment and growth (such as UK Electricity Transmission) to cash generative developed assets with minimal investment requirements (such as National Grid Metering, included within Other activities).
		We generate 95% of our revenue from our regulated operating segments in the UK and US. We work with our regulators to obtain agreements that balance the risks we face with the opportunity to deliver reasonable returns for our investors. When investing in Other activities we aim to leverage our core capabilities to deliver higher returns for investors.
		Our regulated businesses earn revenue for the transmission, distribution and generation services they have provided during the year. In any one year, the revenue recognised may differ from that allowed under our regulatory agreements and any such timing differences are adjusted through future prices. Our Other activities earn revenue in line with their contractual terms.
		Revenue primarily represents the sales value derived from the generation, transmission and distribution of energy, together with the sales value derived from the provision of other services to customers. It excludes value added (sales) tax and intra-group sales.

		Revenue includes an assessment of unbilled energy and transportation services supplied to customers between the date of the last meter reading and the year end. This is estimated based on historical consumption and weather patterns.

		Where revenue exceeds the maximum amount permitted by a regulatory agreement, adjustments will be made to future prices to reflect this over-recovery. No liability is recognised, as such an adjustment relates to the provision of future services. Similarly no asset is recognised where a regulatory agreement permits adjustments to be made to future prices in respect of an under-recovery.

		We present revenue and the results of the business analysed by operating segment, based on the information the Board of Directors uses internally for the purposes of evaluating the performance of operating segments and determining resource allocation between operating segments. The Board of Directors is National Grid’s chief operating decision-making body (as defined by IFRS 8 ‘Operating Segments’) and assesses the performance of operations principally on the basis of operating profit before exceptional items, remeasurements and stranded cost recoveries (see note 4).

		There have been no changes to our reporting structure for the year ended 31 March 2015.

		2. Segmental analysis continued

		The following table describes the main activities for each operating segment:
		UK Electricity Transmission				High voltage electricity transmission networks in Great Britain.
		UK Gas Transmission				The gas transmission network in Great Britain and UK LNG storage activities.
		UK Gas Distribution				Four of the eight regional networks of Great Britain’s gas distribution system.
		US Regulated				Gas distribution networks, electricity distribution networks and high voltage electricity transmission networks in New York and New England and electricity generation facilities in New York.

		Other activities primarily relate to non-regulated businesses and other commercial operations not included within the above segments, including: the Great Britain-France electricity interconnector; UK based gas metering activities; UK property management; a UK LNG import terminal; US LNG operations; US unregulated transmission pipelines; together with corporate activities.

		Sales between operating segments are priced considering the regulatory and legal requirements to which the businesses are subject. The analysis of revenue by geographical area is on the basis of destination. There are no material sales between the UK and US geographical areas.

Unaudited commentary on the results of our principal operations by segment

As a business, we have three measures of operating profit that are used on a regular basis and disclosed in this Annual Report.

Statutory operating profit: This is operating profit as calculated under International Financial Reporting Standards (IFRS). Statutory operating profit by segment is shown in note 2 on page 98.

Adjusted operating profit: Adjusted operating profit (business performance) excludes items that if included could distort understanding of our performance for the year and the comparability between periods. Further details of items that are excluded in adjusted operating profit are shown in note 4 on page 103.

Regulatory financial performance: This is particularly relevant for our UK operations and is a measure of operating profit that reflects the impact of the businesses’ regulatory arrangements when presenting financial performance.

Reconciliations between statutory and adjusted operating profit can be found on page 186. Reconciliations between adjusted operating profit and regulatory financial performance for UK Electricity Transmission, UK Gas Transmission and UK Gas Distribution can be found on page 100.

Commentary on segmental adjusted operating profit results

We have summarised the results of our principal operating segments here by segment to provide direct reference to the results as disclosed in note 2. This analysis has been prepared based on adjusted operating profit (operating profit before exceptional items, remeasurements and stranded cost recoveries) as set out in note 2(b).

UK Electricity Transmission

For the year ended 31 March 2015, revenue in the UK Electricity Transmission segment was £367m higher at £3,754m, and adjusted operating profit increased by £150m to £1,237m.

Net regulated income after pass-through costs was £230m higher, principally reflecting increases in allowed Transmission Owner revenues this year and a £43m benefit relating to legal settlements. This was partially offset by under-recoveries of allowed revenue in the year of £89m compared with under-recoveries of £60m in the prior year. Regulated controllable costs were £14m higher due to inflation, organisational change costs and additional tower maintenance costs. Depreciation and amortisation was £33m higher reflecting the continued capital investment programme (investment in the year was £1,074m). Other costs were £4m higher than prior year.

UK Gas Transmission

Revenue in the UK Gas Transmission segment increased by £81m in 2014/15 to £1,022m and adjusted operating profit increased by £20m to £437m.

Net regulated income after pass-through costs was £42m higher due to earned gas permit and constraints management incentives. In addition, under-recoveries of allowed revenue in the year of £18m

were £3m favourable to last year’s under-recoveries of £21m. Partially offsetting the revenue gains, regulated controllable costs were £8m higher, mainly as a result of additional system operator costs relating to EU work and some organisation change costs.

Other operating costs were also £17m higher, including a £13m provision for decommissioning the Avonmouth LNG plant.

Capital investment remained around the same level as last year at £184m.

UK Gas Distribution

UK Gas Distribution revenue decreased by £31m in 2014/15 to £1,867m, and adjusted operating profit decreased by £78m to £826m.

Net regulated income after pass-through costs was £11m lower, reflecting changes in allowed revenues for replacement expenditure (repex). Timing differences reduced net revenues by a further £16m, with £13m over-recoveries in 2014/15, compared with a £29m over-recovery in the prior year. Regulated controllable costs were £22m higher primarily due to inflation and some organisation change costs. Depreciation and amortisation was £15m higher reflecting the continued capital investment programme (investment in the year was £498m). Other costs were £14m higher, reflecting a provision for additional asset protection costs.

US Regulated

Revenue in our US Regulated businesses was £54m lower in 2014/15 at £7,986m, while adjusted operating profit increased by £39m to £1,164m.

The stronger dollar increased operating profit in the year by £30m. Excluding the impact of foreign exchange, net regulated income increased by £81m, reflecting increased revenue from existing rate plans, including capex trackers, together with additional income from gas customer growth, partially offset by the impact of the end of LIPA management services activities (MSA) in December 2013. In addition, over-recoveries of allowed revenues in the year of £30m were £20m favourable to last year’s over-recoveries of £10m. Regulated controllable costs increased by £17m excluding the impact of foreign exchange, as a result of increased gas leak and compliance work and additional costs incurred to improve data quality and bring regulatory filings up to date, partly offset by the cessation of costs associated with the LIPA MSA activities. Bad debt costs were £62m higher excluding the impact of foreign exchange, following last year’s exceptionally cold winter. There were no major storms affecting our operations in the years ended 31 March 2014 and 2015.

Our capital investment programme continues in the US, with a further £1,501m invested in 2014/15, including gas leak reduction programmes and electricity capacity and reinforcement work.

Other activities

Revenue in Other activities increased by £26m to £762m in the year ended 31 March 2015. Adjusted operating profit was £68m higher at £199m.

Operating profit in the French interconnector was £18m higher as a result of strong auction revenues this year. In the US, corporate and other activities losses were £63m lower, mainly as a result of our finance system upgrade completing in the first half of this year. Capital investment in our Other activities was £33m higher at £213m.

Unaudited commentary on the results of our principal operations by segment continued

Commentary on UK regulated financial performance

The regulated financial performance calculation provides a measure of the performance of the regulated operations before the impacts of interest and taxation. It adjusts reported operating profit under IFRS to reflect the impact of the businesses’ regulatory arrangements when presenting financial performance.

Adjustments in calculating regulatory financial performance

The principal adjustments from reported operating profit to UK regulated financial performance are:

Movement in UK regulatory ‘IOUs’: Revenue related to performance in one year may be recovered in later years. Revenue may be recovered in one year but be required to be returned to customers in future years. IFRS recognises these revenues when they flow through invoices to customers and not in the period to which they relate.

Performance RAV: UK performance efficiencies are in part remunerated by the creation of additional RAV which is expected to result in future earnings under regulatory arrangements.

Pension adjustment: Cash payments against pension deficits in the UK are recoverable under regulatory contracts.

3% RAV indexation: Future UK revenues expected to be set using an asset base adjusted for inflation. This will be billed in future periods and recognised under IFRS at that time.

UK deferred taxation adjustment: Future UK revenues are expected to recover cash taxation cost including the unwinding of deferred taxation balances created in the current year.

Regulatory depreciation: US and UK regulated revenues include allowance for a return of regulatory capital in accordance with regulatory assumed asset lives. This return does not form part of regulatory profit.

Fast/slow money adjustment: The regulatory remuneration of costs incurred is split between in year revenue allowances and the creation of additional RAV. This does not align with the classification of costs as operating costs and fixed asset additions under IFRS accounting principles.

UK Electricity Transmission

Regulated financial performance for UK Electricity Transmission increased to £1,232m from £1,066m, up 16%. The year on year movement reflected the higher opening regulated asset value and the higher achieved operational return on equity. There was also a one-off benefit of £56m from legal settlements. These were partially offset by a reduced price control ‘tracker’ cost of debt allowance.

UK Gas Transmission

Regulated financial performance for UK Gas Transmission increased to £648m from £552m, up 17%. This reflected improved operational return on equity, mainly as a result of incentive performance, and the increase in underlying revenues associated with increased regulated asset value. This was partly offset by lower allowed cost of debt (2.72% real compared with 2.92% real in 2013/14).

UK Gas Distribution

Regulated financial performance for UK Gas Distribution decreased to £819m from £855m. The year on year movement in regulated financial performance reflected an increase in underlying revenues associated with increased regulated asset value, more than offset by lower allowed cost of debt and a slightly reduced achieved return on equity.

1. The audit fees for the year ended 31 March 2014 have been restated to reflect the final audit fee following completion of the statutory audit process. 2. Audit fees in each year represent fees for the audit of the Company’s financial statements and regulatory reporting for the years ended 31 March 2015, 2014 and 2013, and the review of interim financial statements for the six month periods ended 30 September 2014, 2013 and 2012 respectively. 3. Other services supplied represent fees payable for services in relation to other statutory filings or engagements that are required to be carried out by the auditors. In particular, this includes fees for reports under section 404 of the US Public Company Accounting Reform and Investor Protection Act of 2002 (Sarbanes-Oxley) and audit reports on regulatory returns. 4. There were no audit related fees as described in Item 16C(b) of Form 20-F. 5. Tax fees include amounts charged for tax compliance, tax advice and tax planning. 6. All other fees include amounts relating to market research on the metering industry and sundry services, all of which have been subject to approval by the Audit Committee. Total other fees for the year ended 31 March 2015 were £0.4m (2014: £0.9m; 2013: £1.5m).

In addition, fees of £0.2m were incurred in 2015 in relation to the audits of the pension schemes of the Company (2014: £0.1m; 2013: £0.1m).

Subject to the Company’s Articles of Association and the Companies Act 2006, the Audit Committee is solely and directly responsible for the approval of the appointment, reappointment, compensation and oversight of the Company’s independent auditors. It is our policy that the Audit Committee must approve in advance all non-audit work in excess of £50,000 to be performed by the independent auditors to ensure that the service will not compromise auditor independence. The Committee has delegated the approval in advance for all non-audit work below this level to the Finance Director. Certain services are prohibited from being performed by the external auditors under the Sarbanes-Oxley Act 2002.

		4. Exceptional items, remeasurements and stranded cost recoveries
		To monitor our financial performance, we use a profit measure that excludes certain income and expenses. We call that measure ‘business performance’ or ‘adjusted profit’. We exclude items from business performance because, if included, these items could distort understanding of our performance for the year and the comparability between periods. This note analyses these items, which are included in our results for the year but are excluded from business performance.

		Our financial performance is analysed into two components: business performance, which excludes exceptional items, remeasurements and stranded cost recoveries; and exceptional items, remeasurements and stranded cost recoveries. Business performance is used by management to monitor financial performance as it is considered that it improves the comparability of our reported financial performance from year to year. Business performance subtotals are presented on the face of the income statement or in the notes to the financial statements.

		Items of income or expense that are considered by management for designation as exceptional items include such items as significant restructurings, write-downs or impairments of non-current assets, significant changes in environmental or decommissioning provisions, integration of acquired businesses, gains or losses on disposals of businesses or investments and significant debt redemption costs as a consequence of transactions such as significant disposals or issues of equity.

		Costs arising from restructuring programmes include redundancy costs. Redundancy costs are charged to the income statement in the year in which a commitment is made to incur the costs and the main features of the restructuring plan have been announced to affected employees.

		Remeasurements comprise gains or losses recorded in the income statement arising from changes in the fair value of commodity contracts and of derivative financial instruments to the extent that hedge accounting is not achieved or is not effective. These fair values increase or decrease because of changes in commodity and financial indices and prices over which we have no control.

		Stranded cost recoveries represent the recovery, through charges to electricity customers in upstate New York and New England, of historical generation-related costs, related to generation assets that are no longer owned by National Grid. Such costs have been recovered from customers as permitted by regulatory agreements, which was completed by 31 March 2013.

1. No exceptional restructuring costs have been incurred in the year ended 31 March 2015. Restructuring costs for 2014 included: costs related to the continued restructuring of our UK operations in preparedness to deliver RIIO, other transformation-related initiatives in the UK and US and an associated software impairment for licences that will no longer be used. For the year ended 31 March 2013, restructuring costs included: costs for the restructuring of our UK operations of £66m in preparedness for delivering RIIO; costs for transformation-related initiatives in the UK and US of £31m; and a credit of £10m for the release of restructuring provisions in the UK recognised in prior years. 2. No further provision (2014: £79m) has been made for the demolition of non-operational gas holders in the UK. 3. For the year ended 31 March 2014, a net gain of £254m was recognised. This included a pension curtailment and settlement (£214m) for employees who transferred to a new employer following the cessation of the Management Services Agreement (MSA) with the Long Island Power Authority (LIPA) on 31 December 2013. There was also a gain of £142m following the extinguishment of debt obligations of £98m and a £56m cash payment received, in compensation for the Company forgiving an historical pension receivable and carrying charges. These gains were offset by transition costs and other provisions incurred to effect the transition. 4. During the year ended 31 March 2014, £16m was received following the sale to a third party of a settlement award which arose as a result of a legal ruling in 2008. 5. For the year ended 31 March 2013, we recognised a gain of £3m on the disposal of two subsidiaries in New Hampshire. 6. Remeasurements – commodity contracts represent mark-to-market movements on certain physical and financial commodity contract obligations in the US. These contracts primarily relate to the forward purchase of energy for supply to customers, or to the economic hedging thereof, that are required to be measured at fair value and that do not qualify for hedge accounting. Under the existing rate plans in the US, commodity costs are recoverable from customers although the timing of recovery may differ from the pattern of costs incurred. 7. For the year ended 31 March 2013, stranded cost recoveries of £14m substantially represented the release of an unutilised provision recognised in a prior period. 8. Represents costs arising from a liability management programme. We have reviewed and restructured the Group debt portfolio following the commencement of the RIIO price controls in 2013 and the slow down in our planned short term UK capital investment programme as the industry assesses the impact of EMR. This resulted in a bond repurchase programme with a notional value of £924m. 9. Remeasurements – net (losses)/gains on derivative financial instruments comprise (losses)/gains arising on derivative financial instruments reported in the income statement. These exclude gains and losses for which hedge accounting has been effective, which have been recognised directly in other comprehensive income or which are offset by adjustments to the carrying value of debt. The tax charge in the year includes a credit of £1m (2014: £nil; 2013: £1m) in respect of prior years. 10. The Finance Act 2013 enacted reductions in the UK corporation tax rate from 23% to 21% from 1 April 2014, and from 21% to 20% from 1 April 2015. Other UK tax legislation also reduced the UK corporation tax rate in prior periods (2013: from 24% to 23%). These reductions have resulted in decreases to UK deferred tax liabilities in these periods. 11. The exceptional tax charge in the prior year arose from a net increase in US state income tax rates. Effective from 1 April 2014, the state income tax rate for Massachusetts regulated utilities increased from 6.5% to 8% and, effective from 1 April 2016, the state income tax rate for New York will decrease from 7.1% to 6.5%.

5. Finance income and costs
This note details the interest income generated by our financial assets and interest expense incurred on our financial liabilities. It also includes the expected return on our pensions and other post-retirement assets, which is offset by the interest payable on pensions and other post-retirement obligations and presented on a net basis. In reporting business performance, we adjust net financing costs to exclude any net gains or losses on derivative financial instruments included in remeasurements. In addition, the current year debt redemption costs have been treated as exceptional (see note 4).

1. Interest on funding attributable to assets in the course of construction in the current year was capitalised at a rate of 3.8% (2014: 4.5%; 2013: 4.4%). In the UK, capitalised interest qualifies for a current year tax deduction with tax relief claimed of £24m (2014: £32m). In the US, capitalised interest is added to the cost of plant and qualifies for tax depreciation allowances. 2. Includes a net foreign exchange gain on financing activities of £636m (2014: £268m gain; 2013: £32m loss) offset by foreign exchange gains and losses on derivative financial instruments measured at fair value. 3. Includes a net gain on instruments designated as fair value hedges of £219m (2014: £183m loss; 2013: £67m gain) offset by a net loss of £162m (2014: £205m gain; 2013: £50m loss) arising from fair value adjustments to the carrying value of debt.

		6. Tax
		Tax is payable in the territories where we operate, mainly the UK and the US. This note gives further details of the total tax charge and tax liabilities, including current and deferred tax. The current tax charge is the tax payable on this year’s taxable profits. Deferred tax is an accounting adjustment to provide for tax that is expected to arise in the future due to differences in the accounting and tax bases of profit.
		The tax charge for the period is recognised in the income statement, the statement of comprehensive income or directly in equity, according to the accounting treatment of the related transaction. The tax charge comprises both current and deferred tax. Current tax assets and liabilities are measured at the amounts expected to be recovered from or paid to the tax authorities. The tax rates and tax laws used to compute the amounts are those that have been enacted or substantively enacted by the reporting date. The calculation of the Group’s total tax charge involves a degree of estimation and judgement, and management periodically evaluates positions taken in tax returns with respect to situations in which applicable tax regulation is subject to interpretation and establishes provisions where appropriate on the basis of amounts expected to be paid to the tax authorities. Deferred tax is provided for using the balance sheet liability method and is recognised on temporary differences between the carrying amount of assets and liabilities in the financial statements and the corresponding tax bases used in the computation of taxable profit. Deferred tax liabilities are generally recognised on all taxable temporary differences and deferred tax assets are recognised to the extent that it is probable that taxable profits will be available against which deductible temporary differences can be utilised. However, deferred tax assets and liabilities are not recognised if the temporary differences arise from the initial recognition of goodwill or from the initial recognition of other assets and liabilities in a transaction (other than a business combination) that affects neither the accounting nor the taxable profit or loss. Deferred tax liabilities are recognised on taxable temporary differences arising on investments in subsidiaries and jointly controlled entities except where the Company is able to control the reversal of the temporary difference and it is probable that the temporary difference will not reverse in the foreseeable future. Deferred tax is calculated at the tax rates that are expected to apply in the period when the liability is settled or the asset is realised, based on the tax rates and tax laws that have been enacted or substantively enacted by the reporting date. The carrying amount of deferred tax assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient taxable profits will be available to allow all or part of the deferred tax asset to be recovered. Unrecognised deferred tax assets are reassessed at each reporting date and are recognised to the extent that it has become probable that future taxable profits will allow the deferred tax asset to be recovered. Deferred tax assets and liabilities are offset when there is a legally enforceable right to set off current tax assets against current tax liabilities and when they relate to income taxes levied by the same tax authority and the Company and its subsidiaries intend to settle their current tax assets and liabilities on a net basis.

Deferred tax assets and liabilities are only offset where there is a legally enforceable right of offset and there is an intention to settle the balances net. The deferred tax balances (after offset) for statement of financial position purposes consist solely of deferred tax liabilities of £4,297m (2014: £4,082m). Deferred tax assets in respect of capital losses, trading losses and non-trade deficits have not been recognised as their future recovery is uncertain or not currently anticipated. The deferred tax assets not recognised are as follows:
													2015 £m			2014 £m

Capital losses														250		274
Non-trade deficits														1		1
Trading losses														4		5

The capital losses and non-trade deficits that arise in the UK are available to carry forward indefinitely. However, the capital losses can only be offset against specific types of future capital gains and non-trade deficits against specific future non-trade profits. The trading losses arising in the US have up to a 20 year carry forward time limit. The aggregate amount of temporary differences associated with the unremitted earnings of overseas subsidiaries and joint ventures for which deferred tax liabilities have not been recognised at the reporting date is approximately £773m (2014: £2,118m). No liability is recognised in respect of the differences because the Company and its subsidiaries are in a position to control the timing of the reversal of the temporary differences and it is probable that such differences will not reverse in the foreseeable future. In addition, as a result of UK tax legislation, which largely exempts overseas dividends received, the temporary differences are unlikely to lead to additional tax.

Unaudited commentary on tax

Tax strategy

National Grid manages its tax affairs in a proactive and responsible way in order to comply with all relevant legislation and minimise reputational risk. As a regulated public utility we are very conscious of the need to manage our tax affairs responsibly in the eyes of our stakeholders. We have a good working relationship with all relevant tax authorities and actively engage with them in order to ensure that they are fully aware of our view of the tax implications of our business initiatives. Management responsibility and oversight for our tax strategy, which is approved by the Finance Committee, rests with the Finance Director and the Global Tax and Treasury Director who monitor our tax activities and report to the Finance Committee.

Total UK tax contribution

This is the third year we have disclosed additional information in respect of our total UK tax contribution for consistency and to aid transparency in an area in which there remains significant public interest. As was the case in prior years, the total amount of taxes we pay and collect in the UK year on year is significantly more than just the corporation tax which we pay on our UK profits. Within the total, we again include other taxes paid such as business rates and taxes on employment together with employee taxes and other indirect taxes.

For 2014/15 our total tax contribution to the UK Exchequer was £1.5bn (2013/14: £1.4bn). Taxes borne in 2015 were £761m, a 4% increase on taxes borne in 2014 of £733m and primarily due to higher corporation tax payments in the current year. Our 2013/14 total tax contribution of £1.4bn resulted in National Grid being the 13th highest contributor of UK taxes based on the results of the Hundred Group’s 2014 Total Tax Contribution Survey, a position commensurate with the size of our business and capitalisation relative to other contributors to the Survey. In 2013 we were in 17th position. In 2014 we ranked 9th in respect of taxes borne.

National Grid’s contribution to the UK economy is again broader than just the taxes it pays over to and collects on behalf of HMRC. The Hundred Group’s 2014 Total Tax Contribution Survey ranks National Grid in 4th place in respect of UK capital expenditure on fixed assets. For instance, National Grid’s economic contribution also supports a significant number of UK jobs in our supply chain.

The most significant amounts making up the 2014/15 total tax contribution were as follows:

Tax transparency

The UK tax charge for the year disclosed in the financial statements in accordance with accounting standards and the UK corporation tax paid during the year will differ. For transparency we have included a reconciliation below of the tax charge per the income statement to the UK corporation tax paid in 2014/15.

The tax charge for the Group as reported in the income statement is £617m (2013/14: £284m). The UK tax charge is £437m (2013/14: £51m) and UK corporation tax paid was £353m (2013/14: £329m), with the principal differences between these two measures as follows:


	Year ended 31 March
Reconciliation of UK total tax charge to UK corporation tax paid	2015 £m			2014 £m

Total UK tax charge (current tax £307m (2014: £346m) and deferred tax £130m (2014: £295m credit))		437			51
Adjustment for non-cash deferred tax (charge)/credit		(130	)		295
Adjustments for current tax credit in respect of prior years		2			9

UK current tax charge		309			355
UK corporation tax instalment payments not payable until the following year		(127	)		(179)
UK corporation tax instalment payments in respect of prior years paid in current year		171			153

UK corporation tax paid		353			329

Tax losses

We have total unrecognised deferred tax assets in respect of losses of £255m (2013/14: £280m) of which £250m (2013/14: £274m) are capital losses in the UK as set out above. These losses arose as a result of the disposal of certain businesses or assets and may be available to offset against future capital gains in the UK.

Development of future tax policy

We believe that the continued development of a coherent and transparent tax policy in the UK is critical to help drive growth in the economy.

We continue to contribute to research into the structure of business tax and its economic impact by contributing to the funding of the Oxford University Centre for Business Tax at the Saïd Business School.

We are a member of a number of industry groups which participate in the development of future tax policy, including the Hundred Group, which represents the views of Finance Directors of FTSE 100 companies and several other large UK companies. Our Group Finance Director is Chairman of its Tax Committee. This helps to ensure that we are engaged at the earliest opportunity on tax issues which affect our business. In the current year we have reviewed and responded to a number of HMRC consultations, the subject matter of which directly impacts taxes borne or collected by our business.

7. Earnings per share (EPS)
EPS is the amount of post-tax profit attributable to each ordinary share. Basic EPS is calculated on profit for the year attributable to equity shareholders divided by the weighted average number of shares in issue during the year. Diluted EPS shows what the impact would be if all outstanding share options were exercised and treated as ordinary shares at year end. The weighted average number of shares is increased by additional shares issued as scrip dividends and reduced by shares repurchased by the Company during the year.

Adjusted earnings and EPS, which exclude exceptional items, remeasurements and stranded cost recoveries, are provided to reflect the business performance subtotals used by the Company. For further details of exceptional items, remeasurements and stranded cost recoveries, see note 4. (a) Basic earnings per share

8. Dividends
Dividends represent the return of profits to shareholders. Dividends are paid as an amount per ordinary share held. We retain part of the profits generated in the year to meet future growth plans and pay out the remainder in accordance with our dividend policy.
Interim dividends are recognised when they become payable to the Company’s shareholders. Final dividends are recognised when they are approved by shareholders.
	2015						2014						2013
	Pence per share		Cash dividend paid £m		Scrip dividend £m		Pence per share		Cash dividend paid £m		Scrip dividend £m		Pence per share		Cash dividend paid £m		Scrip dividend £m

		42.25		1,271		315		40.85		1,059		444		39.84		810		623

The Directors are proposing a final dividend for the year ended 31 March 2015 of 28.16p per share that will absorb approximately £1,054m of shareholders’ equity (assuming all amounts are settled in cash). It will be paid on 5 August 2015 to shareholders who are on the register of members at 5 June 2015 and a scrip dividend will be offered as an alternative, subject to shareholders’ approval at the Annual General Meeting.

Unaudited commentary on dividends

Following the announcement of our dividend policy in March 2013, the Board remains confident that National Grid is able to support a dividend growing at least in line with RPI inflation for the foreseeable future, while continuing to invest as required in our regulated assets.

With the exception of the 2013/14 interim dividend paid in January 2014, a scrip option has been offered for all interim and final dividends in the last four years. The scrip take-up as a percentage of total shares outstanding (excluding treasury shares) since 2012/13 was as follows: 2014/15 interim 5%; 2013/14 final 28%; 2013/14 interim n/a; 2012/13 final 46%; and 2012/13 interim 35%.

In August 2014 we began a share buyback programme that will allow us to offer the scrip dividend option for both the full-year and interim dividend. The buyback programme is designed to balance shareholders’ appetite for the scrip dividend option with our desire to operate an efficient balance sheet with appropriate leverage.

		9. Goodwill
		Goodwill represents the excess of what we paid to acquire businesses over the fair value of their net assets at the acquisition date. We assess whether goodwill is recoverable each year by performing an impairment review.
		Goodwill is recognised as an asset and is not amortised, but is tested for impairment annually or more frequently if events or changes in circumstances indicate a potential impairment. Any impairment is recognised immediately in the income statement and is not subsequently reversed. Goodwill and fair value adjustments arising on the acquisition of a foreign entity are treated as assets and liabilities of the foreign entity and translated at the closing exchange rate. Impairment Goodwill is allocated to cash-generating units and this allocation is made to those cash-generating units that are expected to benefit from the business combination in which the goodwill arose. Impairments of goodwill are calculated as the difference between the carrying value of the goodwill and the estimated recoverable amount of the cash-generating unit to which that goodwill has been allocated. Recoverable amount is defined as the higher of fair value less costs to sell and estimated value-in-use at the date the impairment review is undertaken. Value-in-use represents the present value of expected future cash flows, discounted using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset for which the estimates of future cash flows have not been adjusted. Impairments are recognised in the income statement and are disclosed separately.
				Total £m

		Net book value at 1 April 2013		5,028
		Additions		12
		Exchange adjustments		(446)

		Net book value at 31 March 2014		4,594
		Impairment		(12)
		Exchange adjustments		563

		Net book value at 31 March 2015		5,145

		The cost of goodwill at 31 March 2015 was £5,157m (2014: £4,594m) with an accumulated impairment charge of £12m (2014: £nil). The amounts disclosed above as at 31 March 2015 include balances relating to the following cash-generating units: New York £2,964m (2014: £2,640m); Massachusetts £1,108m (2014: £987m); Rhode Island £412m (2014: £367m); and Federal £661m (2014: £600m). Goodwill is reviewed annually for impairment and the recoverability of goodwill has been assessed by comparing the carrying amount of our operations described above (our cash-generating units) with the expected recoverable amount on a value-in-use basis. In each assessment, the value-in-use has been calculated based on five year plan projections that incorporate our best estimates of future cash flows, customer rates, costs, future prices and growth. Such projections reflect our current regulatory rate plans taking into account regulatory arrangements to allow for future rate plan filings and recovery of investment. Our plans have proved to be reliable guides in the past and the Directors believe the estimates are appropriate. The future economic growth rate used to extrapolate projections beyond five years has been maintained at 2.25% (2014: 2.25%). The growth rate has been determined having regard to data on projected growth in US real gross domestic product (GDP). Based on our business’ place in the underlying US economy, it is appropriate for the terminal growth rate to be based upon the overall growth in real GDP and, given the nature of our operations, to extend over a long period of time. Cash flow projections have been discounted to reflect the time value of money, using a pre-tax discount rate of 9% (2014: 9%). The discount rate represents the estimated weighted average cost of capital of these operations. While it is possible that a key assumption in the calculation could change, the Directors believe that no reasonably foreseeable change would result in an impairment of goodwill, in view of the long-term nature of the key assumptions and the margin by which the estimated fair value exceeds the carrying amount. As part of their review, the Directors specifically reviewed the carrying value of goodwill associated with Clean Line Energy Partners LLC. This review resulted in a full impairment being recorded of £12m.

10. Other intangible assets
Other intangible assets include software and acquisition-related assets (such as brand names and customer relationships), which are written down (amortised) over the length of period we expect to receive a benefit from the asset.
Identifiable intangible assets are recorded at cost less accumulated amortisation and any provision for impairment. Other intangible assets are tested for impairment only if there is an indication that the carrying value of the assets may have been impaired. Impairments of assets are calculated as the difference between the carrying value of the asset and the recoverable amount, if lower. Where such an asset does not generate cash flows that are independent from other assets, the recoverable amount of the cash-generating unit to which that asset belongs is estimated. Impairments are recognised in the income statement and are disclosed separately. Any assets which suffered impairment in a previous period are reviewed for possible reversal of the impairment at each reporting date. Internally generated intangible assets, such as software, are recognised only if: an asset is created that can be identified; it is probable that the asset created will generate future economic benefits; and the development cost of the asset can be measured reliably. Where no internally generated intangible asset can be recognised, development expenditure is recorded as an expense in the period in which it is incurred. On a business combination, as well as recording separable intangible assets possessed by the acquired entity at their fair value, identifiable intangible assets that arise from contractual or other legal rights are also included in the statement of financial position at their fair value. Acquisition-related intangible assets principally comprise customer relationships. Other intangible assets are amortised on a straight-line basis over their estimated useful economic lives. Amortisation periods for categories of intangible assets are:

11. Property, plant and equipment
The following note shows the physical assets controlled by us. The cost of these assets primarily represents the amount initially paid for them. A depreciation expense is charged to the income statement to reflect annual wear and tear and the reduced value of the asset over time. Depreciation is calculated by estimating the number of years we expect the asset to be used (useful economic life) and charging the cost of the asset to the income statement equally over this period. Our strategy in action We operate an energy networks business and therefore have a significant physical asset base. We continue to invest in our networks to maintain reliability, create new customer connections and ensure our networks are flexible and resilient. Our business plan envisages these additional investments will be funded through a mixture of cash generated from operations and the issue of new debt.
Property, plant and equipment is recorded at cost, less accumulated depreciation and any impairment losses. Cost includes the purchase price of the asset, any payroll and finance costs incurred which are directly attributable to the construction of property, plant and equipment as well as the cost of any associated asset retirement obligations. Property, plant and equipment includes assets in which the Company’s interest comprises legally protected statutory or contractual rights of use. Additions represent the purchase or construction of new assets, including capital expenditure for safety and environmental assets, and extensions to, enhancements to, or replacement of existing assets. Contributions received prior to 1 July 2009 towards the cost of property, plant and equipment are included in trade and other payables as deferred income and credited on a straight-line basis to the income statement over the estimated useful economic lives of the assets to which they relate. Contributions received post 1 July 2009 are recognised in revenue immediately, except where the contributions are consideration for a future service, in which case they are recognised initially as deferred income and revenue is subsequently recognised over the period in which the service is provided. No depreciation is provided on freehold land or assets in the course of construction. Other items of property, plant and equipment are depreciated, on a straight-line basis, at rates estimated to write off their book values over their estimated useful economic lives. In assessing estimated useful economic lives, consideration is given to any contractual arrangements and operational requirements relating to particular assets. The assessments of estimated useful economic lives and residual values of assets are performed annually. Unless otherwise determined by operational requirements, the depreciation periods for the principal categories of property, plant and equipment are, in general, as shown in the table below:
	Years

Freehold and leasehold buildings		up to 65
Plant and machinery:
Electricity transmission plant		15 to 60
Electricity distribution plant		15 to 60
Electricity generation plant		20 to 40
Interconnector plant		15 to 60
Gas plant – mains, services and regulating equipment		30 to 100
Gas plant – storage		15 to 21
Gas plant – meters		10 to 33
Motor vehicles and office equipment		up to 10

Gains and losses on disposals are determined by comparing the proceeds with the carrying amount and are recognised within operating profit in the income statement. Items within property, plant and equipment are tested for impairment only if there is some indication that the carrying value of the assets may have been impaired. Impairments of assets are calculated as the difference between the carrying value of the asset and the recoverable amount, if lower. Where such an asset does not generate cash flows that are independent from other assets, the recoverable amount of the cash-generating unit to which that asset belongs is estimated. Material impairments are recognised in the income statement and are disclosed separately. Any assets which suffered impairment in a previous period are reviewed for possible reversal of the impairment at each reporting date.

13. Financial and other investments
Financial and other investments include two main categories. Assets classified as available-for-sale typically represent investments in short-term money funds and quoted investments in equities or bonds of other companies. The second category is loans and receivables which includes bank deposits with a maturity of greater than three months, and cash balances that cannot be readily used in operations, principally collateral pledged for certain borrowings.
Financial assets, liabilities and equity instruments are classified according to the substance of the contractual arrangements entered into, and recognised on trade date. Available-for-sale financial assets are non-derivatives that are either designated in this category or not classified in any other categories. Available-for-sale financial investments are recognised at fair value plus directly related incremental transaction costs, and are subsequently carried at fair value in the statement of financial position. Changes in the fair value of available-for-sale investments are recognised directly in other comprehensive income, until the investment is disposed of or is determined to be impaired. At this time the cumulative gain or loss previously recognised in equity is included in the income statement for the period. Investment income is recognised using the effective interest method and taken through interest income in the income statement. Loans receivable and other receivables are initially recognised at fair value and subsequently held at amortised cost using the effective interest method. Interest income, together with gains and losses when the loans and receivables are derecognised or impaired, are recognised in the income statement. Subsequent to initial recognition, the fair values of financial assets measured at fair value that are quoted in active markets are based on bid prices. When independent prices are not available, fair values are determined by using valuation techniques that are consistent with techniques commonly used by the relevant market. The techniques use observable market data.

14. Investments in joint ventures and associates

Investments in joint ventures and associates represent businesses we do not control, but instead exercise joint control or significant influence.

A joint venture is an arrangement established to engage in economic activity, which the Company jointly controls with other parties and has rights to the net assets of the arrangement. An associate is an entity which is neither a subsidiary nor a joint venture, but over which the Company has significant influence.

Outstanding balances with joint ventures and associates are shown in note 28.

15. Derivative financial instruments

Derivatives are financial instruments that derive their value from the price of an underlying item such as interest rates, foreign exchange rates, credit spreads, commodities, equity or other indices. In accordance with Board approved policies, derivatives are transacted to manage our exposure to fluctuations in interest rate and foreign exchange rate on borrowings and other contractual cash flows. Specifically, we use derivatives to manage these risks from our financing portfolio to optimise the overall cost of accessing the debt capital markets. These derivatives are analysed below. We also use derivatives to manage our operational market risks from commodities. The commodity derivative contracts are detailed in note 30(e).

Derivative financial instruments are initially recognised at fair value and subsequently remeasured at fair value at each reporting date. Changes in fair values are recorded in the period they arise, in either the income statement or other comprehensive income depending on the applicable accounting standards. Where the fair value of a derivative is positive it is carried as a derivative asset, and where negative as a derivative liability.

We calculate fair value of the financial derivatives by discounting all future cash flows using the market yield curve at the reporting date. The market yield curve for each currency is obtained from external sources for interest and foreign exchange rates. In the absence of sufficient market data, fair values would be based on the quoted market price of similar derivatives. Analysis of these derivatives and the various methods used to calculate their respective fair values is detailed below and in note 30.

For each class of derivative instrument type the total fair value amounts are as follows:

1. The notional contract amounts of derivatives indicate the gross nominal value of transactions outstanding at the reporting date.

Where possible, derivatives held as hedging instruments are formally designated as hedges as defined in IAS 39. Derivatives may qualify as hedges for accounting purposes if they are fair value hedges, cash flow hedges or net investment hedges. Our use of derivatives may entail a derivative transaction qualifying for one or more hedge type designations under IAS 39.

Hedge accounting allows derivatives to be designated as a hedge of another non-derivative financial instrument, to mitigate the impact of potential volatility in the income statement of changes in the fair value of the derivative instruments. To qualify for hedge accounting, documentation is prepared specifying the hedging strategy, the component transactions and methodology used for effectiveness measurement. National Grid uses three hedge accounting methods, which are described as follows:

Fair value hedges

Fair value hedges principally consist of interest rate and cross-currency swaps that are used to protect against changes in the fair value of fixed-rate, long-term financial instruments due to movements in market interest rates. For qualifying fair value hedges, all changes in the fair value of the derivative and changes in the fair value of the item in relation to the risk being hedged are recognised in the income statement to the extent the fair value hedge is effective. Adjustments made to the carrying amount of the hedged item for fair value hedges will be amortised over the remaining life, in line with the hedged item.

Cash flow hedges

Exposure arises from the variability in future interest and currency cash flows on assets and liabilities which bear interest at variable rates or are in a foreign currency. Interest rate and cross-currency swaps are maintained, and designated as cash flow hedges, where they qualify, to manage this exposure. Fair value changes on designated cash flow hedges are initially recognised directly in the cash flow hedge reserve, as gains or losses recognised in equity and any ineffective portion is recognised immediately in the income statement. Amounts are transferred from equity and recognised in the income statement as the income or expense is recognised on the hedged item.

Forward foreign currency contracts are used to hedge anticipated and committed future currency cash flows. Where these contracts qualify for hedge accounting they are designated as cash flow hedges. On recognition of the underlying transaction in the financial statements, the associated hedge gains and losses, deferred in equity, are transferred and included with the recognition of the underlying transaction.

15. Derivative financial instruments continued Cash flow hedges continued When a forecast transaction is no longer expected to occur, the cumulative gain or loss previously reported in equity is transferred to the income statement. Where a non-financial asset or a non-financial liability results from a forecast transaction or firm commitment being hedged, the amounts deferred in equity are included in the initial measurement of that non-monetary asset or liability.

Net investment hedges Borrowings, cross-currency swaps and forward currency contracts are used in the management of the foreign exchange exposure arising from the investment in non-sterling denominated subsidiaries. Where these contracts qualify for hedge accounting they are designated as net investment hedges.

The cross-currency swaps and forward foreign currency contracts are hedge accounted using the spot to spot method. The foreign exchange gain or loss on retranslation of the borrowings and the spot to spot movements on the cross-currency swaps and forward currency contracts are transferred to equity to offset gains or losses on translation of the net investment in the non-sterling denominated subsidiaries, with any ineffective portion recognised immediately in the income statement. Derivatives not in a formal hedge relationship Our policy is not to use derivatives for trading purposes. However, due to the complex nature of hedge accounting under IAS 39 some derivatives may not qualify for hedge accounting, or are specifically not designated as a hedge where natural offset is more appropriate. Changes in the fair value of any derivative instruments that do not qualify for hedge accounting are recognised in remeasurements within the income statement.

Discontinuation of hedge accounting Hedge accounting is discontinued when the hedging instrument expires or is sold, terminated, exercised or no longer qualifies for hedge accounting. At that time, any cumulative gains or losses relating to cash flow hedges recognised in equity are initially retained in equity and subsequently recognised in the income statement in the same periods in which the previously hedged item affects profit or loss. Amounts deferred in equity with respect to net investment hedges are subsequently recognised in the income statement in the event of the disposal of the overseas operations concerned. For fair value hedges, the cumulative adjustment recorded to the carrying value of the hedged item at the date hedge accounting is discontinued is amortised to the income statement using the effective interest method. Embedded derivatives No adjustment is made with respect to derivative clauses embedded in financial instruments or other contracts that are defined as closely related to those instruments or contracts. Consequently these embedded derivatives are not accounted for separately from the debt instrument. Where there are embedded derivatives in host contracts not closely related, the embedded derivative is separately accounted for as a derivative financial instrument.

16. Inventories and current intangible assets
Inventories represent assets that we intend to use in order to generate revenue in the short term, either by selling the asset itself (for example fuel stocks) or by using it to fulfil a service to a customer or to maintain our network (consumables).
Inventories are stated at the lower of weighted average cost and net realisable value. Where applicable, cost comprises direct materials and direct labour costs as well as those overheads that have been incurred in bringing the inventories to their present location and condition. Emission allowances, principally relating to the emissions of carbon dioxide in the UK and sulphur and nitrous oxides in the US, are recorded as intangible assets within current assets and are initially recorded at cost and subsequently at the lower of cost and net realisable value. Where emission allowances are granted by relevant authorities, cost is deemed to be equal to the fair value at the date of allocation. Receipts of such grants are treated as deferred income, which is recognised in the income statement as the related charges for emissions are recognised or on impairment of the related intangible asset. A provision is recorded in respect of the obligation to deliver emission allowances and emission charges are recognised in the income statement in the period in which emissions are made.

17. Trade and other receivables
Trade and other receivables are amounts which are due from our customers for services (and commodities in the US) we have provided. Other receivables also include prepayments made by us, for example, property lease rentals paid in advance.
Trade and other receivables are initially recognised at fair value and subsequently measured at amortised cost, less any appropriate allowances for estimated irrecoverable amounts. A provision is established for irrecoverable amounts when there is objective evidence that amounts due under the original payment terms will not be collected.

18. Cash and cash equivalents
Cash and cash equivalents include cash balances, together with short-term investments with an original maturity of less than three months that are readily convertible to cash.
Net cash and cash equivalents reflected in the cash flow statement are net of bank overdrafts, which are reported in borrowings. The carrying amounts of cash and cash equivalents and bank overdrafts approximate their fair values. Cash at bank earns interest at floating rates based on daily bank deposit rates. Short-term deposits are made for periods varying between one day and three months, depending on the immediate cash requirements, and earn interest at the respective short-term deposit rates. Net cash and cash equivalents held in currencies other than sterling have been converted into sterling at year-end exchange rates. For further information on currency exposures, refer to note 30(d).

At 31 March 2015, £1m (2014: £24m) of cash and cash equivalents were restricted. This primarily relates to cash held in captive insurance companies. 19. Borrowings
We borrow money primarily in the form of bonds and bank loans. These are for a fixed term and may have fixed or floating interest rates or are linked to RPI. As indicated in note 15, we use derivatives to manage risks associated with interest rates and foreign exchange. Our strategy in action Our price controls and rate plans require us to fund our networks within a certain ratio of debt to equity and, as a result, we have issued a significant amount of debt. As we continue to invest in our networks, the value of debt is expected to increase over time. To maintain a strong balance sheet and to allow us to access capital markets at commercially acceptable interest rates, we balance the amount of debt we issue with the value of our assets, and take account of certain other metrics used by credit rating agencies.
Borrowings, which include interest-bearing and inflation linked debt and overdrafts, are recorded at their initial fair value which normally reflects the proceeds received, net of direct issue costs less any repayments. Subsequently these are stated at amortised cost, using the effective interest method. Any difference between the proceeds after direct issue costs and the redemption value is recognised over the term of the borrowing in the income statement using the effective interest method.

Where market values were not available, fair value of borrowings (Level 2) was £15,520m (2014: £10,743m), calculated by discounting cash flows at prevailing interest rates. The notional amount outstanding of the debt portfolio at 31 March 2015 was £25,419m (2014: £25,539m).
The assets of the Colonial Gas Company and the Niagara Mohawk Power Corporation and certain gas distribution assets of the Narragansett Electric Company are subject to liens and other charges and are provided as collateral over borrowings totalling £424m at 31 March 2015 (2014: £438m).
Collateral is placed with or received from any counterparty where we have entered into a credit support annex to the ISDA Master Agreement once the current mark-to-market valuation of the trades between the parties exceeds an agreed threshold. Included in current bank loans is £540m (2014: £843m) in respect of cash received under collateral agreements. For further details of our borrowing facilities, refer to note 31. For further details of our bonds in issue, please refer to the debt investor section of our website.
Assets held under finance leases are recognised at their fair value or, if lower, the present value of the minimum lease payments on inception. The corresponding liability is recognised as a finance lease obligation within borrowings. Rental payments are apportioned between finance costs and reduction in the finance lease obligation, so as to achieve a constant rate of interest.
Assets held under finance leases are depreciated over the shorter of their useful life and the lease term.

		Unaudited commentary on borrowings
		As at 31 March 2015, total borrowings of £25,910m (2014: £25,950m) including bonds, bank loans, commercial paper, collateral, finance leases and other debt had decreased by £40m. This represents the ongoing refinancing of the debt portfolio. We expect to repay £3,028m of our total borrowings in the next 12 months including commercial paper, collateral and interest, and to fund this repayment through the capital and money markets. The average long-term debt maturity of the portfolio is 13 years (2014: 12 years).
		The maturity profile of long-term debt in our major entities is illustrated below:

20. Trade and other payables
Trade and other payables include amounts owed to suppliers, tax authorities and other parties which are due to be settled within 12 months. The total also includes deferred income, which represents monies received from customers but for which we have not yet delivered the associated service. These amounts are recognised as revenue when the service is provided.

There is no material difference between the fair value and the carrying value of other non-current liabilities.
22. Pensions and other post-retirement benefits
Substantially all our employees are members of either DB (defined benefit) or DC (defined contribution) pension plans. The principal UK plans are the National Grid UK Pension Scheme, the National Grid Electricity Group of the Electricity Supply Pension Scheme and The National Grid YouPlan. In the US, we have a number of plans and also provide healthcare and life insurance benefits to eligible retired US employees.
The fair value of associated plan assets and present value of DB obligations are updated annually. For further details and the actuarial assumptions used to value the obligations, see note 29.
We separately present our UK and US pension plans to show geographical split. Below we provide a more detailed analysis of the amounts recorded in the primary financial statements.
For DC plans, the Group pays contributions into separate funds on behalf of the employee and has no further obligations to employees. The risks associated with this type of plan are assumed by the member.
For DB retirement plans, members receive benefits on retirement, the value of which is dependent on factors such as salary and length of pensionable service. The Group underwrites both financial and demographic risks associated with this type of plan.
The cost of providing benefits in a DB plan is determined using the projected unit method, with actuarial valuations being carried out at each reporting date by a qualified actuary. This valuation method is an accrued benefits valuation method that makes allowance for projected earnings.


126


22. Pensions and other post-retirement benefits continued
The Group’s obligation in respect of DB pension plans is calculated separately for each plan by projecting the estimated amount of future benefit payments that employees have earned for their pensionable service in the current and prior periods. These future benefit payments are discounted to determine the present value of the liabilities and the fair value of plan assets and any unrecognised past service cost is then deducted. The discount rate used is the yield at the valuation date on high-quality corporate bonds.
The Group takes advice from independent actuaries relating to the appropriateness of any key assumptions applied which include life expectancy of members, expected salary and pension increases, and inflation. It should be noted that comparatively small changes in the assumptions used may have a significant effect on the amounts recognised in the income statement and the statement of other comprehensive income and the net liability recognised in the statement of financial position.
Remeasurements of net retirement obligations are recognised in full in the period in which they occur in the statement of other comprehensive income.
Risks
The DB pension obligations and other post-retirement benefit liabilities are exposed to the primary risks outlined below.
Liabilities are calculated using discount rates set with reference to yields on high-quality corporate bonds prevailing in the US and UK debt markets and will fluctuate as yields change. Plan funds are invested in a variety of asset classes, principally: equities, government securities, corporate bonds and property. Consequently, actual returns will differ from the underlying discount rate adopted and therefore have an impact on the net balance sheet liability.
Changes in inflation will affect both current and future pension payments and are partially mitigated through investment in inflation matching assets and hedging instruments.
Longevity is also a key driver of liabilities and changes in expected mortality will have a direct impact on liabilities. The liabilities are, in aggregate, relatively mature which serves to mitigate this risk to some extent.
Each plan’s investment strategy seeks to balance the level of investment return sought with the aim of reducing volatility and risk. In undertaking this approach reference is made both to the maturity of the liabilities and the funding level of that plan. A number of further strategies are employed to manage underlying risks, including liability matching asset strategies, diversification of asset portfolios, interest rate hedging and active management of foreign exchange exposure.

– analysis of items in the primary statements continued


23. Provisions
We make provisions when an obligation exists, resulting from a past event and it is probable that cash will be paid to settle it, but the exact amount of cash required can only be estimated.
The main estimates relate to environmental remediation and decommissioning costs for various sites we own or have owned and other provisions, including restructuring plans and lease contracts we have entered into that are now loss making.
Our strategy in action
We are committed to the protection and enhancement of the environment. However, we have acquired, owned and operated a number of businesses which have, during the course of their operations, created an environmental impact. Therefore we have a provision that reflects the expected cost to remediate these sites. Current operations will seldom result in new sites with significant expected costs being added to the provision.
Provisions are recognised where a legal or constructive obligation exists at the reporting date, as a result of a past event, where the amount of the obligation can be reliably estimated and where the outflow of economic benefit is probable.
Provision is made for decommissioning and environmental costs, based on future estimated expenditures, discounted to present values. An initial estimate of decommissioning and environmental costs attributable to property, plant and equipment is recorded as part of the original cost of the related property, plant and equipment.
Changes in the provision arising from revised estimates or discount rates or changes in the expected timing of expenditures that relate to property, plant and equipment are recorded as adjustments to their carrying value and depreciated prospectively over their remaining estimated useful economic lives; otherwise such changes are recognised in the income statement.
The unwinding of the discount is included within the income statement as a financing charge.

23. Provisions continued

Environmental provision

The environmental provision represents the estimated restoration and remediation costs relating to a number of sites owned and managed by subsidiary undertakings, together with certain US sites that National Grid no longer owns. The environmental provision is as follows:

The remediation expenditure in the UK relates to old gas manufacturing sites and also to electricity transmission sites. Cash flows are expected to be incurred between 2015 and 2060. A number of estimation uncertainties affect the calculation of the provision, including the impact of regulation, accuracy of the site surveys, unexpected contaminants, transportation costs, the impact of alternative technologies and changes in the discount rate. This provision incorporates our best estimate of the financial effect of these uncertainties, but future changes in any of the assumptions could materially impact the calculation of the provision. The undiscounted amount is the undiscounted best estimate of the liability having regard to these uncertainties.

The remediation expenditure in the US is expected to be incurred between 2015 and 2071. The uncertainties regarding the calculation of this provision are similar to those considered in respect of UK sites. This expenditure is expected to be largely recoverable from ratepayers under the terms of various rate agreements in the US.

Decommissioning provision

The decommissioning provision represents £51m (2014: £55m) of expenditure relating to asset retirement obligations expected to be incurred until 2075, and £64m (2014: £72m) of expenditure relating to the demolition of gas holders expected to be incurred until 2022. It also includes the net present value of the estimated expenditure (discounted at a real rate of 2%) expected to be incurred until 2033 in respect of the decommissioning of certain US nuclear generating units that National Grid no longer owns.

Restructuring provision

The restructuring provision principally relates to business reorganisation costs in the UK and is expected to be incurred until 2023.

Emissions provision

The provision for emission costs is expected to be settled using emission allowances granted.

Other provisions

Included within other provisions at 31 March 2015 are amounts provided in respect of onerous lease commitments and rates payable on surplus properties of £117m (2014: £117m) with expenditure expected to be incurred until 2039.

Other provisions also include £182m (2014: £160m) of estimated liabilities in respect of past events insured by insurance subsidiary undertakings, including employer liability claims. In accordance with insurance industry practice, these estimates are based on experience from previous years and there is, therefore, no identifiable payment date. It also includes £13m (2014: £13m) in respect of obligations associated with investments in joint ventures.

24. Share capital
Ordinary share capital represents the total number of shares issued which are publicly traded. We also disclose the number of treasury shares the Company holds, which are shares that the Company has bought itself, predominantly to satisfy employee share option plan liabilities.
Share capital is accounted for as an equity instrument. An equity instrument is any contract that includes a residual interest in the consolidated assets of the Company after deducting all its liabilities and is recorded at the proceeds received, net of direct issue costs, with an amount equal to the nominal amount of the shares issued included in the share capital account and the balance recorded in the share premium account.

1. The issue of shares under the scrip dividend programme is considered to be a bonus issue under the terms of the Companies Act 2006 and the nominal value of the shares is charged to the share premium account.
The share capital of the Company consists of ordinary shares of 11¹⁷⁄₄₃ pence nominal value each including ADSs. The ordinary shares and ADSs allow holders to receive dividends and vote at general meetings of the Company. The Company holds treasury shares but may not exercise any rights over these shares including the entitlement to vote or receive dividends. There are no restrictions on the transfer or sale of ordinary shares.
In line with the provisions of the Companies Act 2006, the Company has amended its Articles of Association and ceased to have authorised share capital.
Treasury shares
At 31 March 2015, the Company held 153m (2014: 124m) of its own shares. The market value of these shares as at 31 March 2015 was £1,323m (2014: £1,019m).
The Company made the following transactions in respect of its own shares during the year ended 31 March 2015:
1. During the year, the Company, as part of management of the dilutive effect of share issuances under the scrip dividend programme, repurchased 37m ordinary shares for aggregate consideration of £338m, including transaction costs. The shares repurchased have a nominal value of £4m and represented approximately 1% of the ordinary shares in issue as at 31 March 2015.
2. During the year, 3m (2014: 2m) treasury shares were gifted to National Grid Employee Share Trusts and 5m (2014: 3m) treasury shares were re-issued in relation to employee share schemes, in total representing approximately 0.2% (2014: 0.1%) of the ordinary shares in issue as at 31 March 2015. The nominal value of these shares was £1m (2014: £1m) and the total proceeds received were £23m (2014: £14m).
3. During the year, the Company made payments totalling £7m (2014: £3m) to National Grid Employee Share Trusts, outside of its share repurchase programme, to enable the trustees to make purchases of National Grid plc shares in order to satisfy the requirements of employee share option and reward plans.
The maximum number of shares held during the year was 153m ordinary shares (2014: 129m) representing approximately 3.9% (2014: 3.4%) of the ordinary shares in issue as at 31 March 2015 and having a nominal value of £17m (2014: £15m).

25. Other equity reserves
Other equity reserves are different categories of equity as required by accounting standards and represent the impact of a number of our historical transactions.
Other equity reserves comprise the translation reserve (see accounting policy B in note 1), cash flow hedge reserve (see note 15), available-for-sale reserve (see note 13), the capital redemption reserve and the merger reserve. The merger reserve arose as a result of the application of merger accounting principles under the then prevailing UK GAAP, which under IFRS 1 was retained for mergers that occurred prior to the IFRS transition date. Under merger accounting principles, the difference between the carrying amount of the capital structure of the acquiring vehicle and that of the acquired business was treated as a merger difference and included within reserves.
As the amounts included in other equity reserves are not attributable to any of the other classes of equity presented, they have been disclosed as a separate classification of equity.

The merger reserve represents the difference between the carrying value of subsidiary undertaking investments and their respective capital structures following the Lattice demerger from BG Group plc and the 1999 Lattice refinancing.
The cash flow hedge reserve on interest rate swap contracts will be continuously transferred to the income statement until the borrowings are repaid. The amount due to be released from reserves to the income statement next year is £15m (pre-tax) and the remainder released with the same maturity profile as borrowings due after more than one year.

26. Net debt
Net debt represents the amount of borrowings and overdrafts less cash, financial investments and related derivatives.
Funding and liquidity risk management is carried out by the treasury function under policies and guidelines approved by the Finance Committee of the Board. The Finance Committee is responsible for the regular review and monitoring of treasury activity and for the approval of specific transactions, the authority for which fall outside the delegation of authority to management.
The primary objective of the treasury function is to manage our funding and liquidity requirements. A secondary objective is to manage the associated financial risks, in the form of interest rate risk and foreign exchange risk, to within pre-authorised parameters. Details of the main risks arising from our financing and commodity hedging activities can be found in the risk factors discussion starting on page 173 and in note 30 to the consolidated financial statements on pages 141 to 148.
Investment of surplus funds, usually in short-term fixed deposits or placements with money market funds that invest in highly liquid instruments of high credit quality, is subject to our counterparty risk management policy.
The movement in cash and cash equivalents is reconciled to movements in net debt.

		– supplementary information


This section includes information that is important to enable a full understanding of our financial position, particularly areas of potential risk that could affect us in the future.
We also include specific disclosures for British Transco Finance Inc., Niagara Mohawk Power Corporation and National Grid Gas plc in accordance with various rules including Rule 3-10 of Regulation S-X (a US SEC requirement), as they have issued public debt securities which have been guaranteed by National Grid plc and one of its subsidiary companies, National Grid Gas plc. Additional disclosures have also been included in respect of the two guarantor companies. These disclosures are in lieu of publishing separate financial statements for these companies. See note 34 for further information.
27. Commitments and contingencies
Commitments are those amounts that we are contractually required to pay in the future as long as the other party meets its obligations. These commitments primarily relate to operating lease rentals, energy purchase agreements and contracts for the repurchase of network assets which, in many cases, extend over a long period of time. We also disclose any contingencies, which include guarantees that companies have given, where we pledge assets against current obligations that will remain for a specific period.

1. Energy purchase commitments relate to contractual commitments to purchase electricity or gas that are used to satisfy physical delivery requirements to our customers or for energy that we use ourselves (i.e. normal purchase, sale or usage) and hence are accounted for as ordinary purchase contracts. Details of commodity contracts that do not meet the normal purchase, sale or usage criteria, and hence are accounted for as derivative contracts, are shown in note 30(e).
The total of future minimum sublease payments expected to be received under non-cancellable subleases is £26m (2014: £21m).
Through the ordinary course of our operations, we are party to various litigation, claims and investigations. We do not expect the ultimate resolution of any of these proceedings to have a material adverse effect on our results of operations, cash flows or financial position.

29. Actuarial information on pensions and other post-retirement benefits

Further details of the DB plans terms and the actuarial assumptions used to value the obligations are set out in this note.

When deciding on these assumptions we take independent actuarial advice. Comparatively small changes in the assumptions applied may have a significant effect on the overall deficit or surplus of a DB plan.

UK pension plans

National Grid’s defined benefit pension arrangements are funded with assets held in separate trustee administered funds. The arrangements are managed by trustee companies with boards consisting of company and member appointed directors. The directors are required to manage the arrangements in accordance with local regulations and the arrangements’ governing documents, acting on behalf of their beneficiaries.

The arrangements are subject to independent actuarial funding valuations at least every three years and following consultation and agreement with us, the qualified actuary certifies the employers’ contribution, which, together with the specified contributions payable by the employees and proceeds from the plans’ assets, are expected to be sufficient to fund the benefits payable. The last full actuarial valuations were carried out as at 31 March 2013. The next valuations are required to be carried out as at 31 March 2016.

1. National Grid UK Pension Scheme

2. National Grid Electricity Group of the Electricity Supply Pension Scheme.

From April 2014 an annual cap was placed on future increases to the salary used to calculate pensions at the lower of 3% or the annual increase in RPI. This capped salary applied to all pensionable service from 1 April 2013 onwards. During the year ended 31 March 2014 these changes resulted in a past service credit of £11m to the income statement (see note 22) and a change to the salary increase assumption which affects how our DB liabilities as at 31 March have been calculated. These changes are to ensure our schemes remain affordable and sustainable over the coming years.

		29. Actuarial information on pensions and other post-retirement benefits continued
		National Grid UK Pension Scheme
		The 2013 actuarial funding valuation showed that, based on long-term financial assumptions, the contribution rate required to meet future benefit accrual was 36% of pensionable earnings (currently 33% by employers and 3% by employees). In addition, National Grid makes payments to the scheme to cover administration costs and the Pension Protection Fund levy.
		Following the 2013 valuation, National Grid and the Trustees agreed a recovery plan which would see the funding deficit repaid by 31 March 2027. Under the schedule of contributions, payments of £60m were made in 2013/14 and £99m in 2014/15 and will thereafter rise in line with RPI until 2026/27. As part of the 2013 agreement, National Grid has established a security arrangement with a charge in favour of the Trustees. At 31 March 2015 the value of this was required to be £397m. This was provided via £300m in letters of credit and approximately £198m in UK Government bonds and cash. The assets held as security will be paid to the scheme in the event that National Grid Gas plc (NGG) is subject to an insolvency event, is given notice of less than 12 months that Ofgem intends to revoke its licence under the Gas Act 1986, or National Grid fails to make the required contributions in relation to the scheme. The assets held as security will be released back to National Grid if the scheme moves into surplus. In addition, National Grid will make a payment of £200m (increased in line with RPI) into the scheme if NGG’s credit rating by two out of three specified agencies falls below certain agreed levels for a period of 40 days.
		This scheme ceased to allow new hires to join from 1 April 2002. A DC section of the scheme was offered for employees joining after this date, which has since been replaced by The National Grid YouPlan (see below).
		National Grid Electricity Group of the Electricity Supply Pension Scheme
		The 2013 actuarial funding valuation showed that, based on long-term financial assumptions, the contribution rate required to meet future benefit accrual was 33.4% of pensionable earnings (currently 27.5% by employers and an average of 5.9% by employees).
		Following the 2013 valuation, National Grid and the Trustees agreed a recovery plan that would see the funding deficit repaid by 31 March 2027. Under the schedule of contributions, a payment of £80m was made in 2013/14 and £46m in 2014/15. Thereafter annual payments are due of £47m in 2015/16 rising in line with RPI until 2026/27. As part of the 2013 agreement, National Grid has established security arrangements with a charge in favour of the Trustees. At 31 March 2015 the value of this was required to be £150m. This was provided via £150m in a letter of credit. In addition, approximately £36m in UK Government bonds and cash was held. The assets held as security will be paid to the scheme in the event that National Grid Electricity Transmission plc (NGET) is subject to an insolvency event, or ceases to hold a licence granted under the Electricity Act 1989. The assets held as security will be released back to National Grid if the scheme moves into surplus. National Grid has also agreed to make a payment in respect of the deficit up to a maximum of £500m should certain triggers be breached; namely if NGET ceases to hold the licence granted under the Electricity Act 1989 or NGET’s credit rating by two out of three specified agencies falls below certain agreed levels for a period of 40 days.
		The scheme closed to new members from 1 April 2006.
		The National Grid YouPlan
		The National Grid YouPlan (YouPlan) is a DC scheme that was launched in 2013 and under the rules of the plan, National Grid double matches contributions to YouPlan up to a maximum of 6% of employee salary. YouPlan is the qualifying scheme used for automatic enrolment and new hires are enrolled into YouPlan.
		US pension plans
		National Grid sponsors numerous non-contributory DB pension plans. The DB plans provide retirement benefits to vested union employees, as well as vested non-union employees hired before 1 January 2011. Benefits under these plans generally reflect age, years of service and compensation and are paid in the form of an annuity or lump sum. An independent actuary performs valuations annually. The Company funds the defined benefit plans by contributing no less than the minimum amount required, but no more than the maximum tax deductible amount allowed under US Internal Revenue Service regulations. The range of contributions based upon these regulations can vary significantly based upon the funded status of the plans. At present, there is some flexibility in the amount that is contributed on an annual basis. In general, the Company’s policy for funding the US pension plans is to contribute the amounts collected in rates and capitalised in the rate base during the year, to the extent that the funding is no less than the minimum amount required. The assets of the plans are held in trusts and administered by fiduciary committees comprised of appointed employees of the Company.
		National Grid also has several DC pension plans, primarily comprised of employee savings and Company matching contributions. Non-union employees hired after 1 January 2011 as well as new hires in 10 groups of represented union employees, receive a core contribution into the DC plan, irrespective of the employee’s contribution into the plan.
		US retiree healthcare and life insurance plans
		National Grid provides healthcare and life insurance benefits to eligible retired US employees. Eligibility is based on certain age and length of service requirements and in most cases retirees contribute to the cost of their healthcare coverage. In the US, there is no governmental requirement to pre-fund post-retirement health and welfare plans. However, in general, the Company’s policy for funding the US retiree healthcare and life insurance plans is to contribute amounts collected in rates and capitalised in the rate base during the year.

1. The discount rates for pension liabilities have been determined by reference to appropriate yields on high-quality corporate bonds prevailing in the UK and US debt markets at the reporting date.

2. A promotional scale has also been used where appropriate. The UK assumption stated is that relating to service prior to 1 April 2014. The UK assumption for the rate of increase in salaries for service after this date is 2.1%.

3. This is the key assumption that determines assumed increases in pensions in payment and deferment in the UK only. The assumptions for the UK were 2.9% (2014: 3.3%; 2013: 3.4%) for increases in pensions in payment and 2.1% (2014: 3.3%; 2013: 3.4%) for increases in pensions in deferment.

30. Financial risk management

Our activities expose us to a variety of financial risks including currency risk, interest rate risk, commodity price risk, credit risk, capital risk and liquidity risk. Our risk management programme focuses on the unpredictability of financial markets and seeks to minimise potential volatility of financial performance from these risks. We use financial instruments, including derivative financial instruments, to manage risks of this type.

This note describes our approach to managing risk, including an analysis of assets and liabilities by currency type and an analysis of interest rate category for our net debt. We are required by accounting standards to also include a number of specific disclosures (such as a maturity analysis of contractual undiscounted cash flows) and have included these requirements below.

Risk management related to financing activities is carried out by a central treasury department under policies approved by the Finance Committee of the Board. The objective of the treasury department is to manage funding and liquidity requirements, including managing associated financial risks, to within acceptable boundaries. The Finance Committee provides written principles for overall risk management, as well as written policies covering specific areas such as foreign exchange risk, interest rate risk, credit risk, liquidity risk, use of derivative financial instruments and non-derivative financial instruments, and investment of excess liquidity.

We have exposure to the following risks, which are described in more detail below:

●

credit risk;

●

liquidity risk;

●

interest rate risk;

●

currency risk;

●

commodity risk; and

●

capital risk.

(a) Credit risk

We are exposed to the risk of loss resulting from counterparties’ default on their commitments including failure to pay or make a delivery on a contract. This risk is inherent in our commercial business activities. We are exposed to credit risk on our cash and cash equivalents, derivative financial instruments, deposits with banks and financial institutions, as well as credit exposures to wholesale and retail customers, including outstanding receivables and committed transactions.

Treasury credit risk

Counterparty risk arises from the investment of surplus funds and from the use of derivative financial instruments. As at 31 March 2015, the following limits were in place for investments held with banks and financial institutions:

Maximum limit

£m

Long-term limit

£m

Triple ‘A’ G8 sovereign entities (AAA)

Unlimited

Triple ‘A’ vehicles (AAA)

548 to 859

Double ‘A+’ G8 sovereign entities (AA+)

Double ‘A’ range institutions (AA)

650 to 818

331 to 409

Single ‘A’ range institutions (A)

224 to 319

114 to 163

As at 31 March 2014 and 2015, we had a number of exposures to individual counterparties. In accordance with our treasury policies, counterparty credit exposure utilisations are monitored daily against the counterparty credit limits. Counterparty credit ratings and market conditions are reviewed continually with limits being revised and utilisation adjusted, if appropriate. Management does not expect any significant losses from non performance by these counterparties.

Commodity credit risk

The credit policy for commodity transactions is owned and monitored by the Executive Energy Risk Committee, under authority delegated by the Board and Executive Committee, and establishes controls and procedures to determine, monitor and minimise the credit risk of counterparties.

Wholesale and retail credit risk

Our principal commercial exposure in the UK is governed by the credit rules within the regulated codes: Uniform Network Code and Connection and Use of System Code. These set out the level of credit relative to the RAV for each credit rating. In the US, we are required to supply electricity and gas under state regulations. Our credit policies and practices are designed to limit credit exposure by collecting security deposits prior to providing utility services, or after utility service has commenced if certain applicable regulatory requirements are met. Collection activities are managed on a daily basis. Sales to retail customers are usually settled in cash, cheques, electronic bank payments or by using major credit cards. We are committed to measuring, monitoring, minimising and recording counterparty credit risk in our wholesale business. The utilisation of credit limits is regularly monitored and collateral is collected against these accounts when necessary. Management does not expect any significant losses of receivables that have not been provided for as shown in note 17.

Offsetting financial assets and liabilities

The following tables set out our financial assets and liabilities which are subject to offset and to enforceable master netting arrangements or similar agreements. The tables show the amounts which are offset and reported net in the statement of financial position. Amounts which cannot be offset under IFRS, but which could be settled net under terms of master netting agreements if certain conditions arise, and with collateral received or pledged, are shown to present National Grid’s net exposure.

Financial assets and liabilities on different transactions are only reported net if the transactions are with the same counterparty, a legal right of offset exists and the cash flows are intended to be settled on a net basis.

Amounts which do not meet the criteria for offsetting on the statement of financial position but could be settled net in certain circumstances principally relate to derivative transactions under ISDA agreements where each party has the option to settle amounts on a net basis in the event of default of the other party.

Commodity contracts that have not been offset on the balance sheet may be settled net in certain circumstances under ISDA or NAESB (North American Energy Standards Board) agreements.

National Grid has similar arrangements in relation to bank account balances and bank overdrafts; and trade payables and trade receivables which are subject to general terms and conditions. However, these balances are immaterial.

(b) Liquidity risk

Our policy is to determine our liquidity requirements by the use of both short-term and long-term cash flow forecasts. These forecasts are supplemented by a financial headroom analysis which is used to assess funding requirements for at least a 24 month period and maintain adequate liquidity for a continuous 12 month period.

We believe our contractual obligations, including those shown in commitments and contingencies in note 27 can be met from existing cash and investments, operating cash flows and other financings that we reasonably expect to be able to secure in the future, together with the use of committed facilities if required.

Our debt agreements and banking facilities contain covenants, including those relating to the periodic and timely provision of financial information by the issuing entity and financial covenants such as restrictions on the level of subsidiary indebtedness. Failure to comply with these covenants, or to obtain waivers of those requirements, could in some cases trigger a right, at the lender’s discretion, to require repayment of some of our debt and may restrict our ability to draw upon our facilities or access the capital markets.

The following is an analysis of the contractual undiscounted cash flows payable under financial liabilities and derivative assets and liabilities as at the reporting date:

1. The interest on borrowings is calculated based on borrowings held at 31 March without taking account of future issues. Floating rate interest is estimated using a forward interest rate curve as at 31 March. Payments are included on the basis of the earliest date on which the Company can be required to settle.

(c) Interest rate risk

National Grid’s interest rate risk arises from our long-term borrowings. Borrowings issued at variable rates expose National Grid to cash flow interest rate risk, partially offset by cash held at variable rates. Borrowings issued at fixed rates expose National Grid to fair value interest rate risk.

Our interest rate risk management policy is to seek to minimise total financing costs (being interest costs and changes in the market value of debt) subject to constraints. We do this by using fixed and floating rate debt and derivative financial instruments including interest rate swaps, swaptions and forward rate agreements.

We hold some borrowings on issue that are inflation linked. We believe that these provide a partial economic offset to the inflation risk associated with our UK inflation linked revenues.

The table in note 19 sets out the carrying amount, by contractual maturity, of borrowings that are exposed to interest rate risk before taking into account interest rate swaps.

During 2015 and 2014, net debt was managed using derivative instruments to hedge interest rate risk as follows:

(d) Currency risk

National Grid operates internationally and is exposed to foreign exchange risk arising from various currency exposures, primarily with respect to the dollar. Foreign exchange risk arises from future commercial transactions, recognised assets and liabilities, and investments in foreign operations.

Our policy for managing foreign exchange transaction risk is to hedge contractually committed foreign currency cash flows over a prescribed minimum size. Where foreign currency cash flow forecasts are less certain, our policy is to hedge a proportion of such cash flows based on the probability of those cash flows occurring. Instruments used to manage foreign exchange transaction risk include foreign exchange forward contracts and foreign exchange swaps.

Our policy for managing foreign exchange translation risk relating to our net investment in foreign operations is to maintain a percentage of net debt and foreign exchange forwards so as to provide an economic offset of our cash flows arising in the foreign currency. The primary managed foreign exchange exposure arises from the dollar denominated assets and liabilities held by our US operations, with a further small euro exposure in respect of a joint venture investment.

During 2015 and 2014, derivative financial instruments were used to manage foreign currency risk as follows:

The carrying amounts of other financial instruments are denominated in the above currencies, which in most instances are the functional currency of the respective subsidiaries. Our exposure to dollars is due to activities in our US subsidiaries. We do not have any other significant exposure to currency risk on these balances.

(e) Commodity risk

We purchase electricity and gas to supply our customers in the US and to meet our own energy needs. Substantially all our costs of purchasing electricity and gas for supply to customers are recoverable at an amount equal to cost. The timing of recovery of these costs can vary between financial periods leading to an under- or over-recovery within any particular year that can lead to large fluctuations in the income statement. We follow approved policies to manage price and supply risks for our commodity activities.

Our energy procurement risk management policy and delegations of authority govern our US commodity trading activities for energy transactions. The purpose of this policy is to ensure we transact within pre-defined risk parameters and only in the physical and financial markets where we or our customers have a physical market requirement. In addition, state regulators require National Grid to manage commodity risk and cost volatility prudently through diversified pricing strategies. In some jurisdictions we are required to file a plan outlining our strategy to be approved by regulators. In certain cases we might receive guidance with regard to specific hedging limits.

Energy purchase contracts for the forward purchase of electricity or gas that are used to satisfy physical delivery requirements to customers or for energy that the Company uses itself meet the normal purchase, sale or usage exemption of IAS 39. They are, therefore, not recognised in the financial statements. Disclosure of commitments under such contracts is made in note 27.

We enter into forward contracts for the purchase of commodities, some of which do not meet the own use exemption for accounting purposes and hence are accounted for as derivatives. We also enter into derivative financial instruments linked to commodity prices, including index-linked futures, swaps and options contracts. These derivative financial instruments are used to manage market price volatility and are carried at fair value on the statement of financial position, with the mark-to-market changes reflected through earnings.

1. Forward electricity purchases have terms up to three years. The contractual obligations under these contracts are £77m (2014: £106m).
2. Forward gas purchases have terms up to five years. The contractual obligations under these contracts are £26m (2014: £171m).
3. NYMEX gas futures have been offset with related margin accounts (see note 30(a)).
(f) Capital risk management The capital structure of the Group consists of shareholders’ equity, as disclosed in the consolidated statement of changes in equity, and net debt (note 26). National Grid’s objectives when managing capital are: to safeguard our ability to continue as a going concern; to remain within regulatory constraints of our regulated operating companies; and to maintain an efficient mix of debt and equity funding thus achieving an optimal capital structure and cost of capital. We regularly review and manage the capital structure as appropriate in order to achieve these objectives.
Maintaining appropriate credit ratings for our regulated companies is an important aspect of our capital risk management strategy and balance sheet efficiency. As noted on page 22, we monitor our balance sheet efficiency using several metrics including our retained cash flow/net debt and interest cover. Interest cover for the year ended 31 March 2015 was 5.1 (2014: 4.1). Our long-term target range for interest cover is greater than 3.0, which we believe is consistent with single A range long-term senior unsecured debt credit ratings within our main UK operating companies, NGET and NGG, based on guidance from the rating agencies.


146


30. Financial risk management continued
(f) Capital risk management continued
In addition, we monitor the RAV gearing within each of NGET and the regulated transmission and distribution businesses within NGG. This is calculated as net debt expressed as a percentage of RAV, and indicates the level of debt employed to fund our UK regulated businesses. It is compared with the level of RAV gearing indicated by Ofgem as being appropriate for these businesses, at around 60 to 65%.
The majority of our regulated operating companies in the US and the UK (and one intermediate UK holding company), are subject to certain restrictions on the payment of dividends by administrative order, contract and/or licence. The types of restrictions that a company may have that would prevent a dividend being declared or paid unless they are met include:
● dividends must be approved in advance by the relevant US state regulatory commission;
● the subsidiary must have at least two recognised rating agency credit ratings of at least investment grade;
● dividends must be limited to cumulative retained earnings, including pre-acquisition retained earnings;
● National Grid plc must maintain an investment grade credit rating and if that rating is the lowest investment grade bond rating it cannot have a negative watch/review for downgrade notice by a credit rating agency;
● the subsidiary must not carry on any activities other than those permitted by the licences;
● the subsidiary must not create any cross-default obligations or give or receive any intra-group cross-subsidies; and
● the percentage of equity compared with total capital of the subsidiary must remain above certain levels.
There is a further restriction relating only to the Narragansett Electric Company, which is required to maintain its consolidated net worth above certain levels.
These restrictions are subject to alteration in the US as and when a new rate case or rate plan is agreed with the relevant regulatory bodies for each operating company and in the UK through the normal licence review process.
As most of our business is regulated, at 31 March 2015 the majority of our net assets are subject to some of the restrictions noted above. These restrictions are not considered to be significantly onerous, nor do we currently expect they will prevent the planned payment of dividends in future in line with our dividend policy.
Some of our regulatory and bank loan agreements additionally impose lower limits for the long-term credit ratings that certain companies within the Group must hold. All the above requirements are monitored on a regular basis in order to ensure compliance. The Company has complied with all externally imposed capital requirements to which it is subject.
(g) Fair value analysis
The financial instruments included on the statement of financial position are measured at fair value. These fair values can be categorised into hierarchy levels that are representative of the inputs used in measuring the fair value. The best evidence of fair value is a quoted price in an actively traded market. In the event that the market for a financial instrument is not active, a valuation technique is used.

(g) Fair value analysis continued

Our level 3 derivative financial instruments include cross-currency swaps with an embedded call option, currency swaps where the currency forward curve is illiquid and inflation linked swaps where the inflation curve is illiquid. In valuing these instruments a third-party valuation is obtained to support each reported fair value.

Our level 3 commodity contracts primarily consist of our forward purchases of electricity and gas where pricing inputs are unobservable, as well as other complex transactions. Complex transactions can introduce the need for internally developed models based on reasonable assumptions. Industry standard valuation techniques such as the Black-Scholes pricing model and Monte Carlo simulation are used for valuing such instruments. Level 3 is also applied in cases when optionality is present or where an extrapolated forward curve is considered unobservable. All published forward curves are verified to market data; if forward curves differ from market data by 5% or more they are considered unobservable.

The changes in value of our level 3 derivative financial instruments are as follows:

31. Borrowing facilities
To support our long-term liquidity requirements and provide backup to commercial paper and other borrowings, we agree loan facilities with financial institutions over and above the value of borrowings that may be required. These facilities have never been drawn, and our undrawn amounts are listed below.
At 31 March 2015, we had bilateral committed credit facilities of £2,094m (2014: £2,073m). In addition, we had committed credit facilities from syndicates of banks of £884m at 31 March 2015 (2014: £800m). All committed credit facilities were undrawn in 2015 and 2014. An analysis of the maturity of these undrawn committed facilities is shown below:

32. Subsidiary undertakings, joint ventures and associates
While we present consolidated results in these financial statements as if we were one company, our legal structure is such that there are a number of different operating and holding companies that contribute to the overall result. This structure has evolved through acquisitions as well as regulatory requirements to have certain activities within separate legal entities.

The Group comprises a large number of entities and it is not practical to include all of them in this list. This list therefore includes brief details for those principal companies which, in the Directors’ opinion, have a significant impact on the revenue, profit or assets of the Group. A full list of subsidiaries, joint ventures and associates is annexed to the Company’s Annual Return filed with the Registrar of Companies.

Our interests and activities are held or operated through subsidiaries, branches, joint arrangements or associates established in – and subject to the laws and regulations of – a number of different jurisdictions.

33. Sensitivities on areas of estimation and uncertainty
In order to give a clearer picture of the impact on our results or financial position of potential changes in significant estimates and assumptions, the following sensitivities are presented. These sensitivities are hypothetical, as they are based on assumptions and conditions prevailing at the year end, and should be used with caution. The effects provided are not necessarily indicative of the actual effects that would be experienced because our actual exposures are constantly changing.

The sensitivities in the tables below show the potential impact in the income statement (and consequential impact on net assets) for a range of different variables each of which have been considered in isolation (i.e. with all other variables remaining constant). There are a number of these sensitivities which are mutually exclusive and therefore if one were to happen, another would not, meaning a total showing how sensitive our results are to these external factors is not meaningful.

We are further required to show additional sensitivity analysis for changes in interest and exchange rates and these are shown separately in the subsequent table due to the additional assumptions that are made in order to produce meaningful sensitivity disclosures.

The sensitivities included in the tables below all have an equal and opposite effect if the sensitivity increases or decreases by the same amount unless otherwise stated. For example, a 10% increase in unbilled revenue at 31 March 2015 would result in an increase in the income statement of £60m and a 10% decrease in unbilled revenue would have the equal but opposite effect.
	2015					2014
	Income statement £m			Net assets £m		Income statement £m			Net assets £m

One year average change in useful economic lives (pre-tax):
Depreciation charge on property, plant and equipment		69			69		68			68
Amortisation charge on intangible assets		26			26		18			18

Estimated future cash flows in respect of provisions, change of 10% (pre-tax)		174			174		164			164

UK change of one year to life expectancy at age 65		1			620		3			548
US change of one year to life expectancy at age 65		3			352		12			220
Assumed US healthcare cost trend rates change of 1%		28			465		28			355

Unbilled revenue at 31 March change of 10% (post-tax)		60			60		58			58
No hedge accounting for our derivative financial instruments (post-tax)		(611	)		316		350			(294)

Commodity risk⁶ (post-tax):
10% increase in commodity prices		26			26		50			50
10% decrease in commodity prices		(24	)		(24)		(33	)		(33)


1. The effect of a 10% change in fair value assumes no hedge accounting. 2. The changes shown are a change in the annual pension or other post-retirement benefit service charge and change in the defined benefit obligations. 3. A change in the discount rate is likely to occur as a result of changes in bond yields and as such would be expected to be offset to a significant degree by a change in the value of the bond assets held by the plans. 4. The projected impact resulting from a change in RPI reflects the underlying effect on pensions in payment, pensions in deferment and resultant increases in salary assumptions. 5. This change has been applied to both the pre 1 April 2014 and post 1 April 2014 rate of increase in salary assumption. 6. Represents potential impact on fair values of commodity contracts only.

1. Excludes sensitivities to LPI curve. Further details on sensitivities are provided in note 30(g). 2. The other equity reserves impact does not reflect the exchange translation in our US subsidiaries’ net assets. It is estimated this would change by £771m (2014: £781m) in the opposite direction if the dollar exchange rate changed by 10%.

		33. Sensitivities on areas of estimation and uncertainty continued

		Pensions and other post-retirement benefits assumptions
		Sensitivities have been prepared to show how the DB obligations and annual service costs could potentially be impacted by changes in the relevant actuarial assumption that were reasonably possible as at 31 March 2015. In preparing sensitivities the potential impact has been calculated by applying the change to each assumption in isolation and assuming all other assumptions remain unchanged. This is with the exception of RPI in the UK where the corresponding change to increases to pensions in payment, increases to pensions in deferment and increases in salary is recognised.

		Financial instruments assumptions
		Our financial instruments are sensitive to changes in market variables, being UK and US interest rates, the UK RPI and the dollar to sterling exchange rate. The changes in market variables impact the valuation of our borrowings, deposits, derivative financial instruments and commodity contracts. The analysis illustrates the sensitivity of our financial instruments to the changes in market variables.

		The following main assumptions were made in calculating the sensitivity analysis: ● the amount of net debt, the ratio of fixed to floating interest rates of the debt and derivatives portfolio, and the proportion of financial instruments in foreign currencies are all constant and on the basis of the hedge designations in place at 31 March 2015 and 2014 respectively; ● the statement of financial position sensitivity to interest rates relates only to derivative financial instruments and available-for-sale investments, as debt and other deposits are carried at amortised cost and so their carrying value does not change as interest rates move; ● the sensitivity of accrued interest to movements in interest rates is calculated on net floating rate exposures on debt, deposits and derivative instruments; ● changes in the carrying value of derivatives from movements in interest rates of designated cash flow hedges are assumed to be recorded fully within equity; and ● changes in the carrying value of derivative financial instruments designated as net investment hedges from movements in interest rates are recorded in the income statement as they are designated using the spot rather than the forward translation method. The impact of movements in the dollar to sterling exchange rate are recorded directly in equity.

		34. Additional disclosures in respect of guaranteed securities
		We have three debt issuances (including preferred shares) that are listed on a US national securities exchange and are guaranteed by other companies in the Group. These guarantors commit to honour any liabilities should the company issuing the debt have any financial difficulties. In order to provide debt holders with information on the financial stability of the companies providing the guarantees, we are required to disclose individual financial information for these companies. We have chosen to include this information in the Group financial statements rather than submitting separate stand-alone financial statements.

		The following condensed consolidating financial information, comprising statements of comprehensive income, statements of financial position and cash flow statements, is given in respect of National Grid Gas plc (subsidiary guarantor), which became joint full and unconditional guarantor on 11 May 2004 with National Grid plc (parent guarantor) of the 6.625% Guaranteed Notes due 2018 issued in June 1998 by British Transco Finance Inc., then known as British Gas Finance Inc. (issuer of notes). Condensed consolidating financial information is also provided in respect of Niagara Mohawk Power Corporation as a result of National Grid plc’s guarantee, dated 29 October 2007, of Niagara Mohawk’s 3.6% and 3.9% issued preferred shares. National Grid Gas plc, British Transco Finance Inc., and Niagara Mohawk Power Corporation are wholly-owned subsidiaries of National Grid plc.
		The following financial information for National Grid plc, National Grid Gas plc, British Transco Finance Inc., and Niagara Mohawk Power Corporation on a condensed consolidating basis is intended to provide investors with meaningful and comparable financial information and is provided pursuant to various rules including Rule 3-10 of Regulation S-X in lieu of the separate financial statements of each subsidiary issuer of public debt securities.

		This financial information should be read in conjunction with the other disclosure in these financial statements.

		Company accounting policies

We are required to include the stand-alone balance sheet of our ultimate parent Company, National Grid plc, under the Companies Act 2006. This is because the publicly traded shares are actually those of National Grid plc (the Company) and the following disclosures provide additional information to shareholders.

D. Foreign currencies

Transactions in currencies other than the functional currency of the Company are recorded at the rates of exchange prevailing on the dates of the transactions. At each balance sheet date, monetary assets and liabilities that are denominated in foreign currencies are retranslated at closing exchange rates. Gains and losses arising on retranslation of monetary assets and liabilities are included in the profit and loss account.

E. Financial instruments

The Company’s accounting policies under UK GAAP, namely FRS 25 ‘Financial Instruments: Presentation’, FRS 26 ‘Financial Instruments: Measurement’ and FRS 29 ‘Financial Instruments: Disclosures’, are the same as the Group’s accounting policies under IFRS, namely IAS 32 ‘Financial Instruments: Presentation’, IAS 39 ‘Financial Instruments: Recognition and Measurement’ and IFRS 7 ‘Financial Instruments: Disclosures’. The Company applies these policies only in respect of the financial instruments that it has, namely investments, derivative financial instruments, debtors, cash at bank and in hand, borrowings and creditors.

The policies are set out in notes 13, 15, 17, 18, 19 and 20 to the consolidated financial statements. The Company is taking the exemption for financial instruments disclosures, because IFRS 7 disclosures are given in notes 30 and 33 to the consolidated financial statements.

F. Hedge accounting

The Company applies the same accounting policy as the Group in respect of fair value hedges and cash flow hedges. This policy is set out in note 15 to the consolidated financial statements.

G. Parent Company guarantees

The Company has guaranteed the repayment of the principal sum, any associated premium and interest on specific loans due by certain subsidiary undertakings primarily to third parties. In the event of default or non performance by the subsidiary, the Company recognises such guarantees as insurance contracts, at fair value with a corresponding increase in the carrying value of the investment.

H. Share awards to employees of subsidiary undertakings

The issuance by the Company to employees of its subsidiaries of a grant over the Company’s options represents additional capital contributions by the Company to its subsidiaries. An additional investment in subsidiaries results in a corresponding increase in shareholders’ equity. The additional capital contribution is based on the fair value of the option at the date of grant, allocated over the underlying grant’s vesting period. Where payments are subsequently received from subsidiaries, these are accounted for as a return of a capital contribution and credited against the Company’s investments in subsidiaries. The Company has no employees.

I. Dividends

Interim dividends are recognised when they are paid to the Company’s shareholders. Final dividends are recognised when they are approved by shareholders.

J. Directors’ remuneration

Full details of directors’ remuneration are disclosed on pages 60 To 75.

A. Basis of preparation of individual financial statements under UK GAAP

These individual financial statements of the Company have been prepared in accordance with applicable UK accounting and financial reporting standards and the Companies Act 2006. They have been prepared on an historical cost basis, except for the revaluation of financial instruments, and are presented in pounds sterling, which is the currency of the primary economic environment in which the Company operates. The 2014 comparative financial information has also been prepared on this basis.

These individual financial statements have been prepared on a going concern basis, which presumes that the Company has adequate resources to remain in operation, and that the Directors intend it to do so, for at least one year from the date the financial statements are signed. Further details of the Directors’ assessment are set out on page 54.

The Company has not presented its own profit and loss account as permitted by section 408 of the Companies Act 2006.

The Company has taken advantage of the exemptions in FRS 8 ‘Related Party Disclosures’ from disclosing transactions with other members of the National Grid plc group of companies.

In accordance with exemptions under FRS 29 ‘Financial Instruments: Disclosures’, the Company has not presented the financial instruments disclosures required by the standard, as disclosures which comply with the standard are included in the consolidated financial statements.

B. Fixed asset investments

Investments held as fixed assets are stated at cost less any provisions for impairment. Investments are reviewed for impairment if events or changes in circumstances indicate that the carrying amount may not be recoverable. Impairments are calculated such that the carrying value of the fixed asset investment is the lower of its cost or recoverable amount. Recoverable amount is the higher of its net realisable value and its value-in-use.

C. Tax

Current tax for the current and prior periods is provided at the amount expected to be paid or recovered using the tax rates and tax laws that have been enacted or substantively enacted by the balance sheet date.

Deferred tax is provided in full on timing differences which result in an obligation at the balance sheet date to pay more tax, or the right to pay less tax, at a future date, at tax rates expected to apply when the timing differences reverse based on tax rates and tax laws that have been enacted or substantively enacted by the balance sheet date. Timing differences arise from the inclusion of items of income and expenditure in tax computations in periods different from those in which they are included in the financial statements.

Deferred tax assets are recognised to the extent that it is regarded as more likely than not that they will be recovered. Deferred tax assets and liabilities are not discounted.

UK regulation Our licences are established under the Gas Act 1986 and Electricity Act 1989, as amended (the Acts). They require us to develop, maintain and operate economic and efficient networks and to facilitate competition in the supply of gas and electricity in Great Britain. They also give us statutory powers. These include the right to bury our pipes or cables under public highways and the ability to use compulsory powers to purchase land so we can conduct our business. Our networks are regulated by Ofgem, which has established price control mechanisms that set the amount of revenue that our regulated businesses can earn. Price control regulation is designed to make sure our interests, as a monopoly, are balanced with those of our customers. Ofgem allows us to charge reasonable, but not excessive, prices. This gives us a future level of revenue that is sufficient to meet our statutory duties and licence obligations, and makes a reasonable return on our investment. The price control includes a number of mechanisms designed to help achieve its objectives. These include financial incentives that encourage us to:		RIIO price controls On 1 April 2013, our UK regulator introduced a new regulatory framework called RIIO (revenue = incentives + innovation + outputs), which lasts for eight years. The building blocks of the RIIO price control are broadly similar to the historical price controls used in the UK. However, there are some significant differences in the mechanics of the calculations. How is revenue calculated? Under RIIO the outputs we deliver are clearly articulated and are integrally linked to the calculation of our allowed revenue. These outputs have been determined through an extensive consultation process, which has given stakeholders a greater opportunity to influence the decisions. The clarity around outputs should lead to greater transparency in how we deliver them. The six output categories are: Safety: ensuring the provision of a safe energy network. Reliability (and availability): promoting networks capable of delivering long-term reliability, as well as minimising the number and duration of interruptions experienced over the price control period, and ensuring adaptation to climate change. Environmental impact: encouraging companies to play their role in achieving broader environmental objectives – specifically, facilitating the reduction of carbon emissions – as well as minimising their own carbon footprint. Customer and stakeholder satisfaction: maintaining high levels of customer satisfaction and stakeholder engagement, and improving service levels. Customer connections: encouraging networks to connect customers quickly and efficiently. Social obligations (UK Gas Distribution only): extending the gas network to communities that are fuel poor where it is efficient to do so, and introducing measures to address carbon monoxide poisoning incidents. Within each of these output categories are a number of primary and secondary deliverables, reflecting what our stakeholders want us to deliver over the coming price control period. The nature and number of these deliverables varies according to the output category, with some being linked directly to our allowed revenue, some linked to legislation, and others having only a reputational impact. Ofgem, using information we have submitted, along with independent assessments, determines the efficient level of expected costs necessary to deliver them. Under RIIO this is known as totex, which is total allowable expenditure, and is similar to the sum of what was controllable opex, capex (and repex for UK Gas Distribution) under the previous price control periods. A number of assumptions are necessary in setting these outputs, such as certain prices or the volumes of work that will be needed. Consequently, there are a number of uncertainty mechanisms within the RIIO framework that can result in adjustments to totex if actual prices or volumes differ from the assumptions. These mechanisms protect us and our customers from windfall gains and losses.
●	continuously improve the cost and effectiveness of our services;
●	manage and operate our networks efficiently;
●	deliver high-quality services to our customers and wider stakeholder community; and
●	invest in developing the network in a way that ensures long-term security of supply.
Our UK Electricity Transmission (UK ET), UK Gas Transmission (UK GT) and UK Gas Distribution (UK GD) businesses operate under eight separate price controls in the UK. These comprise two for our UK ET operations, one covering our role as transmission owner (TO) and the other for our role as system operator (SO); two for our UK GT operations, again one as TO and one as SO; and one for each of our four regional gas distribution networks. While each of the eight price controls may have differing terms, they are based on a consistent regulatory framework. In addition to the eight price controls, our LNG storage business has a price control covering some aspects of its operations. There is also a tariff cap price control applied to certain elements of domestic metering and daily meter reading activities carried out by National Grid Metering. Interconnectors derive their revenues from congestion revenues. Congestion revenues depend on the existence of price differentials between markets at either end of the interconnector. European legislation governs how capacity is allocated. It requires all interconnection capacity to be allocated to the market through auctions. There are a range of different regulatory models available for interconnector projects. These involve various levels of regulatory insight ranging from fully merchant (the project is reliant on revenues selling interconnector capacity) to ‘cap and floor’ (where revenues above the cap are returned to system users and revenues below the floor are topped by system users thus reducing the overall project risk).


166

Where we under- or over-spend the allowed totex for reasons that are not covered by uncertainty mechanisms, there is a sharing factor. This means the under- or over-spend is shared between us and customers through an adjustment to allowed revenues in a future year. This sharing factor provides an incentive for us to provide the outputs efficiently, as we are able to keep a portion of the savings, with the remainder benefiting our customers.

This sharing factor is one of the ways that RIIO has given innovation more prominence. Innovation includes traditional areas such as new technologies, as well as the broader challenge of finding new ways of working to deliver outputs more efficiently. This broader challenge has an impact on everyone in our business.

Totex is then split between fast and slow money – a new concept under RIIO, based on a specified percentage. Fast money represents the amount of totex we are able to recover in the current year. Slow money is added to our RAV. For more details on the sharing factors under RIIO, please see the table below.

RIIO regulatory building blocks

LOGO

Allowed returns

The cost of capital allowed under RIIO is as follows:

Transmission

Gas Distribution

Gas

Electricity

In addition to fast money, in each year we are allowed to collect a depreciation of and a return on our RAV.

This works in a similar way to the previous price control. However, there have been changes to the asset lives for electricity transmission (transition from 20 years to 45 years evenly across the RIIO period) and the depreciation calculation for UK GD (changed from 45 years straight line to 45 years sum of digits for assets added post 2002). We are also allowed to collect additional revenues related to non-controllable costs and incentives.

The incentive mechanisms can increase or decrease our allowed revenue and result from our performance against various measures related to our outputs. RIIO has introduced new incentive mechanisms as a way to provide further incentives to align our objectives with those of our customers and other stakeholders. For example, performance against our customer satisfaction targets can have a positive or negative effect of up to 1% of allowed annual revenues. Incentives will normally affect our revenues two years after the year of performance.

Features of our rate plans

We bill our customers for their use of electricity and gas services. Customer bills typically comprise a commodity charge, covering the cost of the electricity or gas delivered, and charges covering our delivery service. With the exception of residential gas customers in Rhode Island, our customers are allowed to select an unregulated competitive supplier for the supply component of electricity and gas utility services. A substantial proportion of our costs, in particular electricity and gas commodity purchases, are pass-through costs, meaning they are fully recoverable from our customers. These pass-through costs are recovered through separate charges to customers that are designed to recover those costs with no profit. Rates are adjusted from time to time to make sure that any over- or under-recovery of these costs is returned to, or recovered from, our customers.

Our FERC-regulated transmission companies use formula rates (instead of rate cases) to set rates annually to recover their cost of service. Through the use of annual true-ups, formula rates recover our actual costs incurred and the allowed RoE based on the actual transmission rate base each year. The company must make annual formula rate filings documenting the revenue requirement, which customers can review and challenge.

Revenue for our wholesale transmission businesses in New England and New York is collected from wholesale transmission customers, who are typically other utilities and include our own New England electricity distribution businesses. With the exception of upstate New York, which continues to combine retail transmission and distribution rates to end-use customers, these wholesale transmission costs are incurred by distribution utilities on behalf of their customers and are fully recovered as a pass-through from end-use customers as approved by each state commission.

Our Long Island generation plants sell capacity to LIPA under 15 year and 25 year power supply agreements, and within wholesale tariffs approved by FERC. Through the use of cost-based formula rates these long-term contracts provide a similar economic effect to cost of service rate regulation.

US regulatory filings

The objectives of our rate case filings are to make sure we have the right cost of service with the ability to earn a fair and reasonable rate of return, while providing safe, reliable and economical service to our customers. In order to achieve these objectives and to reduce regulatory lag, we have been requesting structural changes, such as revenue decoupling mechanisms, capital trackers, commodity-related bad debt true-ups and pension and other post-employment benefit true-ups, separately from base rates. These terms are explained below the table on page 172.

Below we summarise significant developments in rate filings and the regulatory environment during the year. We completed the final stabilisation upgrade to our new financial systems in July 2014. The new systems will facilitate future regulatory filings and capture the benefit of the increased investments in asset replacement, network reliability and customer growth. Planning has started to prepare suitable ‘test years’ to support new regulatory filings. We expect to make a number of such filings over the next two to three years to update the capital investment allowances and rate base across many of our businesses. Specifically, we anticipate that KEDLI, KEDNY, and Massachusetts Electric will file applications for new rate plans with their regulators during the 12 months ending 31 March 2016. Moreover, as part of current regulatory initiatives, we will file proposals for investments in grid modernisation in Massachusetts and for innovative technology deployments and service offerings as part of the Reforming the Energy Vision effort

in New York. Effective 1 April 2015, we implemented changes to our US management structure to strengthen our jurisdictional focus and address recommendations made by our regulators, including giving jurisdictional presidents more authority over operations and other functions.

Massachusetts

Capital investment programmes

Most recently, on the electricity side, MADPU allowed approximately $12 million into rates effective from 1 March 2015, related to $170 million of plant investments made in 2013.

On the gas side, MADPU allowed approximately $15 million into rates effective from 1 November 2014, related to $134 million of plant investment made in 2013. Additionally, recent legislation in Massachusetts grants us greater ability to cost effectively accelerate the replacement of our ageing gas infrastructure by receiving concurrent cost recovery for eligible capital investments. We submitted a plan to MADPU on 31 October 2014 to replace all eligible ageing gas infrastructure on our system within 20 years by increasing the annual replacement rate by approximately 50% within the next 10 years, and then maintaining this replacement rate for the remainder of the programme. On 30 April 2015, MADPU approved our proposal to place an additional $9.7 million into rates effective from 1 May 2015, related to $175 million of anticipated investments in 2015 under this accelerated pipe replacement plan.

Solar investment legislation

Recent legislation extended our ability to construct, own and operate a total of up to 25 MW of solar facilities within our electricity service territory if the facilities are constructed by 30 June 2016. On 28 June 2014, MADPU approved our proposal for up to 20 MW of solar facilities, in addition to the 4.6 MW of solar generation that we already own and operate under the same legislation. MADPU also pre-approved an amount not to exceed $97.6 million for ownership costs, lease expenses and property tax expenses associated with the solar facilities. We have entered into contracts with developers to deliver constructed solar generation facilities by 2015, and will petition MADPU for cost recovery in 2016 once the solar facilities become operational.

Storm fund recovery

The Massachusetts electricity business collects $4.3 million annually in base rates to credit towards a storm fund devoted to fund major storm restoration efforts. The severity and frequency of storms in Massachusetts over the last few years left our storm fund in a deficit position of approximately $212 million. On 3 May 2013, MADPU allowed us to begin collecting $40 million annually for three years, and an additional $7.3 million from 1 July 2014, towards the replenishment of the storm fund, subject to a review of the prudency of the underlying costs. That review is under way, with evidentiary hearings scheduled for May 2015. The funding of the remaining deficit will be addressed as part of the prudency review and in future rate proceedings, if necessary.

Storm management audit

MADPU’s December 2012 order regarding our performance during Tropical Storm Irene and the October 2011 snowstorm required us to undergo an independent audit regarding our storm management. MADPU adopted the auditor’s 30 recommendations, which included items such as improving emergency response training and tracking of training, designating additional personnel for storm roles, and considering the expanded use of technology and communication tools. The Company has already implemented 12 of the recommendations and is in the process of implementing the remaining recommendations.

Grid modernisation

MADPU is increasingly focused on improving service and reliability to customers, with a focus on greater choice for customers and integrating distributed energy resources. MADPU has directed the Company to file a grid modernisation plan in August 2015 that demonstrates how the Company will make measurable progress towards reducing the effect of outages, optimising demand, integrating distributed resources and improving workforce and asset management. The grid modernisation plan represents a new capital investment opportunity for the Company. MADPU established criteria that, if met, would allow the capital costs from the plan to be recovered through a separate capital recovery mechanism.

Additionally, the Company’s Worcester, Massachusetts Smart Energy Solutions pilot began on 1 January 2015. The pilot is testing grid modernisation technologies for approximately 15,000 customers, with a goal of reducing peak and average loads by 5%. The Company has an opportunity to earn a performance incentive if load reduction exceeds 5%. The Company filed on 15 September 2014 to recover $11 million of costs incurred in 2012 and 2013 to implement this pilot. MADPU is currently reviewing the Company’s request and a decision is expected in early 2016.

Service quality

MADPU issued its final order and service quality guidelines for all gas and electricity companies on 22 December 2014. The order shifted the goal of the service quality guidelines from preventing the deterioration of performance to improved service quality. The reasons stated by MADPU included that: the companies are able to achieve higher levels of service quality than in 2002, when the guidelines were first implemented; customers expect improved levels of service quality; and advances in available technologies and the expected grid modernisation efforts of the electricity companies will help them meet the new standards and at a more reasonable cost. In shifting the goals of service quality, MADPU made changes to the current service quality structure, including removing financial offsets to penalties, setting state-wide benchmarks and changing the calculation of benchmarks and penalties. The new guidelines are effective from 1 January 2015. However, there is a motion for clarification and reconsideration currently pending before MADPU on this matter.

New York

Upstate New York 2012 rate plan filing

Effective from 1 April 2014, the upstate New York electricity and gas businesses entered the second year of their three year rate plan. The rate plan provides an increase in the electricity delivery revenue requirement of $51.4 million and $28.3 million for rate years two and three, respectively. For the gas operations, the rate plan provides an increase of $5.9 million and $6.3 million in rate years two and three, respectively.

Reforming the Energy Vision (REV)

In April 2014, the NYPSC instituted the REV proceeding, which considers options for a new regulatory and operational model for electricity utilities that includes a greater emphasis on incorporating distributed energy resources (DER) via market mechanisms. The NYPSC envisions a new role for utilities as distributed system platform (DSP) providers who create markets for DER and more fully integrate DER in distribution system operations and planning. The REV proceeding’s objectives include: enhanced customer energy choices and control; improved electricity system efficiency, reliability, and resiliency; and cleaner more diverse electricity generation. In February 2015, the NYPSC issued an order addressing various technical, policy, and market design issues.

The NYPSC is expected to address ratemaking issues in 2015. Implementation of the DSP role and greater DER integration will probably require incremental investments in utility infrastructure.

2013 New York gas management audit

In October 2014, the NYPSC issued a report on the results of the comprehensive management and operations audit of National Grid’s three New York gas distribution utilities. New York law requires periodic management audits of all utilities at least once every five years. We last underwent a management audit in 2009 when the NYPSC audited Niagara Mohawk’s electricity business.

The audit found that our operations performed well in providing reliable gas service and noted strength in operations, network planning, project management, work management, load forecasting, supply procurement and customer systems support. The audit report offered 31 recommendations aimed at promoting improvement in the performance of our New York gas businesses, including recommendations around strengthening of the National Grid US jurisdictional operating model, enhancing the service level agreements between the operating companies and supporting functions and corporate governance. We generally accept the recommendations presented in the report, and are currently working to implement the recommendations in a manner that will deliver the greatest value to our gas customers. To address the recommendation that the National Grid USA Board include at least one independent director, Therese Esperdy was elected to the Board of Directors with effect from 1 May 2015. In our next major gas rate proceeding, the NYPSC will consider our effectiveness in implementing the audit recommendations and seek to reflect the costs and savings associated with the recommendations in rates.

KEDLI gas investment plan

In June 2014, KEDLI petitioned the NYPSC for approval of a deferral mechanism related to a proposed gas infrastructure investment programme. In December 2014, the NYPSC approved two gas investment plans for calendar years 2015 and 2016, one for leak-prone pipe capital expenditures (capped at $211.7 million in total) and one for gas service expansion expenditures (capped at $202.9 million in total). The NYPSC approved a surcharge to begin recovery of the deferred leak-prone pipeline investment costs, allowing for the recovery up to a total of $23.4 million through a surcharge effective from 1 April 2015 until the end of 2016. KEDLI received approval to establish a new deferral accounting mechanism for the balance of the approved costs not covered by the surcharge.

KEDNY rate plan extension

In June 2013, the NYPSC approved a two year extension of KEDNY’s five year rate settlement, extending the rate plan until the end of 2014. The NYPSC modified KEDNY’s capital tracker to be a downward-only net utility plant reconciliation mechanism, covering the cumulative two year term ending 31 December 2014. The extension of KEDNY’s rate settlement included increased capital investment allowances for 2013 and 2014.

Rhode Island

Rhode Island 2014/15 electricity and gas infrastructure, safety and reliability (ISR) plans

State law provides our Rhode Island gas and electricity operating divisions with rate mechanisms that allow for the recovery of capital investment, including a return, and certain expenses outside base rate proceedings through the submission of annual ISR plans.


170

In December 2014, we filed with the RIPUC for review and approval of our annual ISR plans for the electricity and gas systems. RIPUC approved the 2016 ISR plans on 31 March 2015. The electricity ISR plan encompasses a $73.3 million spending programme for capital investment and $12.1 million for operating and maintenance expenses for vegetation management and inspection and maintenance. The gas ISR plan encompasses $76.8 million for capital investment and incremental operation and maintenance expense for the hiring and training of additional personnel to support increases in leak-prone pipe replacement.

Rhode Island Renewable Energy Growth Program

In June 2014, the Rhode Island legislature enacted legislation to facilitate and promote installation of distributed renewable energy generation. As a result, in November 2014, we filed with RIPUC a proposal to implement the Rhode Island Renewable Energy Growth Program, which replaces our current programme and will create a feed-in-tariff (FIT) programme to support a total of 160 MW of renewable distributed generation projects over a five year period. The FIT payments will be determined via competitive solicitations for larger projects. The current programme provides long-term contracts, or power purchase agreements, to renewable energy projects. RIPUC approved the new programme on 31 March 2015. Under Rhode Island law, we can recover the incremental costs associated with the programme and are entitled to earn incentives equal to 1.75% of the gross payments made under the FIT.

FERC

Complaints on New England transmission allowed RoE

In September 2011, December 2012 and July 2014, complaints were filed with FERC against certain transmission owners, including our New England electricity transmission business, to lower the base RoE from the FERC approved rate of 11.14%. In orders addressing the September 2011 complaint issued in June 2014, October 2014 and March 2015, FERC set the base RoE for the first complaint’s 15 month historical refund period and for a prospective period beginning in October 2014 at 10.57%. In these orders, FERC also found that the total or maximum RoE for our New England transmission business, including various RoE incentive adders authorised by FERC, cannot exceed 11.74% during these periods.

FERC has scheduled hearings on the December 2012 and July 2014 New England RoE complaints in June 2015, with non-binding preliminary findings due by the end of 2015. A FERC order acting on these preliminary findings is not expected until the end of 2016.

Complaints on New York transmission allowed RoE

In September 2012, November 2012 and February 2014, complaints were filed with FERC against our New York electricity transmission subsidiary to lower the total RoE from the FERC approved rate of 11.5% and to modify certain other aspects of our New York transmission formula rates. In September 2014, FERC set these three complaints for settlement and hearing procedures. In December 2014, we reached a settlement agreement in principle with the complainants to resolve these complaints. In May 2015, FERC approved the uncontested settlement agreement.

Short-term borrowing authorisation

In October 2014, National Grid filed an application with FERC on behalf of all electricity public utility subsidiaries, with the exception of Massachusetts Electric Company (MECo), seeking to re-establish the Commission’s authorisation to issue short-term debt, as required by Section 204 of the Federal Power Act. National Grid’s short-term borrowing authorisation had expired on 30 November 2013, as issues related to the implementation of the US enterprise resource planning system had rendered National Grid temporarily unable to provide FERC with the financial reports

required for such approval. FERC granted the application in December 2014. MECo was omitted from the application because it did not satisfy the interest coverage calculation typically required for approval. National Grid intends to file on behalf of MECo as soon as practicable, and in the interim MECo’s short-term cash needs will be met through capital contributions in the form of equity.

New York Transco

On 14 November 2014, the four New York investor-owned utilities (IOUs), including Niagara Mohawk Power Corporation, formed NY Transco LLC, a New York company whose sole business will be to plan, develop, construct and own major new high voltage electricity transmission projects across New York State. In early December 2014, the four IOUs and NY Transco filed on behalf of NY Transco an application with FERC to establish a formula rate, rate incentives and cost allocation for a portfolio of five new transmission projects with a combined estimated total cost of over $1.7 billion. A number of entities intervened in the docket and challenged various aspects of the application. In April 2015, FERC approved certain elements of our filing (including some rate incentives), rejected others, and set the remainder for hearing and settlement.

New England gas and electricity interdependency

The region’s electricity and gas systems have become increasingly interdependent as the region’s reliance on gas-fired electricity generation has grown without commensurate pipeline infrastructure expansion, resulting in severe constraints at certain times of the year. These constraints have restricted gas availability for generation and decreased electricity reliability. They have also resulted in significant increases to spot gas prices for electricity generation, driving significant increases to the region’s wholesale and retail electricity costs. To address this challenge, New England’s governors have established an initiative envisaging coordinated strategic infrastructure investments focused on expanding the region’s energy portfolio.

We are working with representatives from several states, other regional electricity and gas utilities, interstate gas pipelines, state regulators, and FERC in realising the governors’ goals. We have put forward structural proposals which would support the development of additional gas pipeline infrastructure to serve the region’s needs and are also developing electricity transmission proposals to increase the ability to deliver clean low carbon energy to enable a balanced solution to the region’s energy needs.

FERC Order 1000

Issued in 2011, Order 1000 was FERC’s major policy order intended to foster regional and inter-regional transmission planning, address transmission needs driven by public policy requirements and increase competition in the electric transmission industry. In 2014 and 2015, FERC issued orders on filings made by the New York and New England system operators to comply with Order 1000 and continue to implement a package of reforms addressing transmission planning and cost allocation. A federal court upheld key provisions of Order 1000 against legal challenges in an August 2014 decision. Policies to comply with Order 1000 have been in effect in New York since January 2014 and became effective in New England in May 2015. The competitive transmission planning processes instituted under Order 1000 have opened National Grid’s service territory to competition from non-incumbent transmission developers and also created opportunities for National Grid to compete for transmission projects outside of the Company’s current geographic footprint.

		Summary of US price controls and rate plans

		^†Revenue decoupling A mechanism that removes the link between a utility’s revenue and sales volume so that the utility is indifferent to changes in usage. Revenues are reconciled to a revenue target, with differences billed or credited to customers. Allows the utility to support energy efficiency. ^‡Capital tracker A mechanism that allows for the recovery of the revenue requirement of incremental capital investment above that embedded in base rates, including depreciation, property taxes and a return on the incremental investment.						^§Commodity-related bad debt true-up A mechanism that allows a utility to reconcile commodity-related bad debt to either actual commodity-related bad debt or to a specified commodity-related bad debt write-off percentage. For electricity utilities, this mechanism also includes working capital. ¯ Pension/OPEB true-up A mechanism that reconciles the actual non-capitalised costs of pension and OPEB and the actual amount recovered in base rates. The difference may be amortised and recovered over a period or deferred for a future rate case.

		Internal control and risk factors


		Disclosure controls Working with management, including the Chief Executive and Finance Director, we have evaluated the effectiveness of the design and operation of our disclosure controls and procedures as at 31 March 2015. Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives, however, the effectiveness of any system of disclosure controls and procedures has limitations including the possibility of human error and the circumvention or overriding of the controls and procedures. Even effective disclosure controls and procedures provide only reasonable assurance of achieving their objectives. Based on the evaluation, the Chief Executive and Finance Director concluded that the disclosure controls and procedures are effective to provide reasonable assurance that information required to be disclosed in the reports that we file and submit under the Exchange Act is recorded, processed, summarised and reported as and when required and that such information is accumulated and communicated to our management, including the Chief Executive and Finance Director, as appropriate, to allow timely decisions regarding disclosure. Internal control over financial reporting Our management, including the Chief Executive and Finance Director, has carried out an evaluation of our internal control over financial reporting pursuant to the Disclosure and Transparency Rules and Section 404 of the Sarbanes-Oxley Act 2002. As required by Section 404, management is responsible for establishing and maintaining an adequate system of internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act). Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.						Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Management evaluation of the effectiveness of the Company’s internal control over financial reporting was based on the revised Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, management concluded that our internal control over financial reporting was effective as at 31 March 2015. PricewaterhouseCoopers LLP, which has audited our consolidated financial statements for the year ended 31 March 2015, has also audited the effectiveness of our internal control over financial reporting. Their attestation report can be found on page 85. During the year, there were no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, it. Risk factors Management of our risks is an important part of our internal control environment, as we describe on pages 38 to 41. In addition to the principal risks listed we face a number of inherent risks that could have a material adverse effect on our business, financial condition, results of operations and reputation, as well as the value and liquidity of our securities. Any investment decision regarding our securities and any forward-looking statements made by us should be considered in the light of these risk factors and the cautionary statement set out on the inside back cover. An overview of the key inherent risks we face is provided below.

		Risk factors
		Potentially harmful activities

		Aspects of the work we do could potentially harm employees, contractors, members of the public or the environment. Potentially hazardous activities that arise in connection with our business include the generation, transmission and distribution of electricity and the storage, transmission and distribution of gas. Electricity and gas utilities also typically use and generate hazardous and potentially hazardous products and by-products. In addition, there may be other aspects of our operations that are not currently regarded or proved to have adverse effects but could become so, such as the effects of electric and magnetic fields. A significant safety or environmental incident, or the failure of our safety processes or of our occupational health plans, as well as the breach of our regulatory or contractual obligations or our climate change targets, could materially adversely affect our results of operations and our reputation. We commit significant resources and expenditure to process safety and to monitoring personal safety, occupational health and environmental performance, and to meeting our obligations under negotiated settlements.						We are subject to laws and regulations in the UK and US governing health and safety matters to protect the public and our employees and contractors, who could potentially be harmed by these activities as well as laws and regulations relating to pollution, the protection of the environment, and the use and disposal of hazardous substances and waste materials. These expose us to costs and liabilities relating to our operations and properties, including those inherited from predecessor bodies, whether currently or formerly owned by us, and sites used for the disposal of our waste. The cost of future environmental remediation obligations is often inherently difficult to estimate and uncertainties can include the extent of contamination, the appropriate corrective actions and our share of the liability. We are increasingly subject to regulation in relation to climate change and are affected by requirements to reduce our own carbon emissions as well as to enable reduction in energy use by our customers. If more onerous requirements are imposed or our ability to recover these costs under regulatory frameworks changes, this could have a material adverse impact on our business, reputation, results of operations and financial position.

Risk factors
Infrastructure and IT systems
We may suffer a major network failure or interruption, or may not be able to carry out critical operations due to the failure of infrastructure, data or technology or a lack of supply. Operational performance could be materially adversely affected by a failure to maintain the health of our assets or networks, inadequate forecasting of demand, inadequate record keeping or control of data or failure of information systems and supporting technology. This in turn could cause us to fail to meet agreed standards of service, incentive and reliability targets, or be in breach of a licence, approval, regulatory requirement or contractual obligation. Even incidents that do not amount to a breach could result in adverse regulatory and financial consequences, as well as harming our reputation. Where demand for electricity or gas exceeds supply and our balancing mechanisms are not able to mitigate this fully, a lack of supply to consumers may damage our reputation. In addition to these risks, we may be affected by other potential events that are largely outside our control, such as the impact of weather (including as a result of climate change and major storms), unlawful or unintentional acts of third parties, insufficient or unreliable supply or force majeure.		Weather conditions can affect financial performance and severe weather that causes outages or damages infrastructure together with our actual or perceived response could materially adversely affect operational and potentially business performance and our reputation. Malicious attack, sabotage or other intentional acts, including breaches of our cyber security, may also damage our assets (which include critical national infrastructure) or otherwise significantly affect corporate activities and, as a consequence, have a material adverse impact on our reputation, business, results of operations and financial condition. Unauthorised access to, or deliberate breaches of, our IT systems may also lead to manipulation of our proprietary business data or customer information. Unauthorised access to private customer information may make us liable for a violation of data privacy regulations. Even where we establish business continuity controls and security against threats against our systems, these may not be sufficient.
Law and regulation
Changes in law or regulation or decisions by governmental bodies or regulators could materially adversely affect us. Most of our businesses are utilities or networks subject to regulation by governments and other authorities. Changes in law or regulation or regulatory policy and precedent, including decisions of governmental bodies or regulators, in the countries or states in which we operate could materially adversely affect us. If we fail to engage in the energy policy debate, we may not be able to influence future energy policy and deliver our strategy. Decisions or rulings concerning, for example:		advancing energy technologies, whether aspects of our activities are contestable, the level of permitted revenues and dividend distributions for our businesses and in relation to proposed business development activities, could have a material adverse impact on our results of operations, cash flows, the financial condition of our businesses and the ability to develop those businesses in the future. Following the introduction of EMR, there has been an increased focus (from some of our stakeholders) on the potential conflicting duties of our transmission and system operator roles, which may damage our reputation. The remediation plans in place or being implemented to address control weaknesses in our US business may not operate as expected, as a result of which we may be unable to provide timely regulatory reporting, which may include the provision of financial statements. This could result in the imposition of regulatory fines, penalties and other sanctions, which could impact our operations, our reputation and our relationship with our regulators and other stakeholders. For further information see pages 166 to 172, which explain our regulatory environment in detail.
(i)	whether licences, approvals or agreements to operate or supply are granted, amended or renewed, whether consents for construction projects are granted in a timely manner or whether there has been any breach of the terms of a licence, approval or regulatory requirement; and
(ii)	timely recovery of incurred expenditure or obligations, the ability to pass through commodity costs, a decoupling of energy usage and revenue, and other decisions relating to the impact of general economic conditions on us, our markets and customers, implications of climate change and of

Business performance
Current and future business performance may not meet our expectations or those of our regulators and shareholders. Earnings maintenance and growth from our regulated gas and electricity businesses will be affected by our ability to meet or exceed efficiency targets and service quality standards set by, or agreed with, our regulators.		If we do not meet these targets and standards, or if we do not implement the transformation projects we are carrying out as envisaged, including to our US enterprise resource planning systems and controls over financial reporting, or are not able to deliver our RIIO operating model and the US Elevate 2018 strategy successfully, we may not achieve the expected benefits, our business may be materially adversely affected and our performance, results of operations and reputation may be materially harmed and we may be in breach of regulatory or contractual obligations.


174


		Risk factors
		Growth and business development activity
		Failure to respond to external market developments and execute our growth strategy may negatively affect our performance. Conversely, new businesses or activities that we undertake alone or with partners may not deliver target outcomes and may expose us to additional operational and financial risk. Failure to grow our core business sufficiently and have viable options for new future business over the longer term could negatively affect the Group’s credibility and reputation and jeopardise the achievement of intended financial returns. Business development activities and the delivery of our growth ambition, including acquisitions, disposals, joint ventures, partnering and organic investment opportunities (including organic investments made as a result of changes to the energy mix), are subject to a wide range of both external uncertainties (including the availability of potential investment targets and		attractive financing and the impact of competition for onshore transmission in both the UK and US), and internal uncertainties (including actual performance of our various existing operating companies and our business planning model assumptions and ability to integrate acquired businesses effectively). As a result, we may suffer unanticipated costs and liabilities and other unanticipated effects. We may also be liable for the past acts, omissions or liabilities of companies or businesses we have acquired, which may be unforeseen or greater than anticipated. In the case of joint ventures, we may have limited control over operations and our joint venture partners may have interests that diverge from our own. The occurrence of any of these events could have a material adverse impact on our results of operations or financial condition, and could also impact our ability to enter into other transactions.
		Cost escalation
		Changes in foreign currency rates, interest rates or commodity prices could materially impact earnings or our financial condition. We have significant operations in the US and so are subject to the exchange rate risks normally associated with non UK operations, including the need to translate US assets and liabilities, and income and expenses, into sterling, our primary reporting currency. In addition, our results of operations and net debt position may be affected because a significant proportion of our borrowings, derivative financial instruments and commodity contracts are		affected by changes in interest rates, commodity price indices and exchange rates, in particular the dollar to sterling exchange rate. Furthermore, our cash flow may be materially affected as a result of settling hedging arrangements entered into to manage our exchange rate, interest rate and commodity price exposure, or by cash collateral movements relating to derivative market values, which also depend on the sterling exchange rate into euro and other currencies.
		Our results of operations could be affected by inflation or deflation. In our regulated UK networks, our allowed revenues are set in real terms and then adjusted for actual RPI inflation. There is a risk that inflationary impacts on our costs are higher than RPI inflation and are not fully compensated by this inflation adjustment to revenues. There is also a risk that year-on-year RPI inflation is negative with no corresponding decrease in costs or insufficient decrease to offset the impact on revenues.		Our income under our rate plans in the US is not typically linked to inflation. In periods of inflation in the US, our operating costs may increase by more than our revenues. In both the UK and US such increased costs may materially adversely affect the results of our operations.
		We may be required to make significant contributions to fund pension and other post-retirement benefits. We participate in a number of pension schemes that together cover substantially all our employees. In both the UK and US, the principal schemes are DB schemes where the scheme assets are held independently of our own financial resources. In the US, we also have other post-retirement benefit schemes. Estimates of the amount and timing of future funding for the UK and US schemes are based on actuarial assumptions and other factors including: the actual and projected market performance of the scheme assets; future long-term bond yields; average life expectancies; and relevant legal requirements.		Actual performance of scheme assets may be affected by volatility in debt and equity markets. Changes in these assumptions or other factors may require us to make additional contributions to these pension schemes which, to the extent they are not recoverable under our price controls or state rate plans, could materially adversely affect the results of our operations and financial condition.

		Risk factors
		Financing and liquidity
		An inability to access capital markets at commercially acceptable interest rates could affect how we maintain and grow our businesses. Our businesses are financed through cash generated from our ongoing operations, bank lending facilities and the capital markets, particularly the long-term debt capital markets. Some of the debt we issue is rated by credit rating agencies and changes to these ratings may affect both our borrowing capacity and borrowing costs. In addition, restrictions imposed by regulators may also limit how we service the financial requirements of our current businesses or the financing of newly acquired or developing businesses. Financial markets can be subject to periods of volatility and shortages of liquidity. If we were unable to access the capital markets or other sources of finance at competitive rates for a prolonged period, our cost of financing may increase, the discretionary and uncommitted elements of our proposed capital investment programme may need to be reconsidered and the manner in which we implement our strategy may need to be reassessed. Such events could have a material adverse impact on our business, results of operations and prospects. Some of our regulatory agreements impose lower limits for the long-term senior unsecured debt credit ratings that certain companies within the Group must hold or the amount of equity within their capital structures.		One of the principal limits requires National Grid plc to hold an investment grade long-term senior unsecured debt credit rating. In addition, some of our regulatory arrangements impose restrictions on the way we can operate. These include regulatory requirements for us to maintain adequate financial resources within certain parts of our operating businesses and may restrict the ability of National Grid plc and some of our subsidiaries to engage in certain transactions, including paying dividends, lending cash and levying charges. The inability to meet such requirements or the occurrence of any such restrictions may have a material adverse impact on our business and financial condition. The remediation plans in place or being implemented to address control weaknesses in our US business may not operate as expected, as a result of which we may be unable to provide accurate financial information to our debt investors in a timely manner. Our debt agreements and banking facilities contain covenants, including those relating to the periodic and timely provision of financial information by the issuing entity and financial covenants, such as restrictions on the level of subsidiary indebtedness. Failure to comply with these covenants, or to obtain waivers of those requirements, could in some cases trigger a right, at the lender’s discretion, to require repayment of some of our debt and may restrict our ability to draw upon our facilities or access the capital markets.
		Customers and counterparties
		Customers and counterparties may not perform their obligations. Our operations are exposed to the risk that customers, suppliers, banks and other financial institutions and others with whom we do business will not satisfy their obligations, which could materially adversely affect our financial position. This risk is significant where our subsidiaries have concentrations of receivables from gas and electricity utilities and their affiliates, such as from our previous LIPA managed services agreement (MSA) and current PSEG-LI transition services agreement (TSA), as well as industrial customers and other purchasers, and may also arise where customers are unable to pay us as a result of increasing commodity prices or adverse economic conditions.		To the extent that counterparties are contracted with for physical commodities (gas and electricity) and they experience events that impact their own ability to deliver, we may suffer supply interruption as described in Infrastructure and IT systems on page 174. There is also a risk to us where we invest excess cash or enter into derivatives and other financial contracts with banks or other financial institutions. Banks who provide us with credit facilities may also fail to perform under those contracts.
		Employees and others
		We may fail to attract, develop and retain employees with the competencies, including leadership and business capabilities, values and behaviours required to deliver our strategy and vision and ensure they are engaged to act in our best interests. Our ability to implement our strategy depends on the capabilities and performance of our employees and leadership at all levels of the business. Our ability to implement our strategy and vision may be negatively affected by the loss of key personnel or an inability to attract, integrate, engage and retain appropriately qualified		personnel, or if significant disputes arise with our employees. As a result, there may be a material adverse effect on our business, financial condition, results of operations and prospects. There is a risk that an employee or someone acting on our behalf may breach our internal controls or internal governance framework or may contravene applicable laws and regulations. This could have an impact on the results of our operations, our reputation and our relationship with our regulators and other stakeholders.

Articles of Association

The following description is a summary of the material terms of our Articles and applicable English law. It is a summary only and is qualified in its entirety by reference to the Articles.

Summary

The Articles set out the Company’s internal regulations. Copies are available on our website and upon request. Amendments to the Articles have to be approved by at least 75% of those voting at a general meeting of the Company. Subject to company law and the Articles, the Directors may exercise all the powers of the Company. They may delegate authorities to committees and day-to-day management and decision-making to individual Executive Directors. The committee structure is set out on page 49.

General

The Company is incorporated under the name National Grid plc and is registered in England and Wales with registered number 04031152. Under the Companies Act 2006, the Company’s objects are unrestricted.

Directors

Under the Articles, a Director must disclose any personal interest in a matter and may not vote in respect of that matter, subject to certain limited exceptions. As permitted under the Companies Act 2006, the Articles allow non conflicted Directors of the Company to authorise a conflict or potential conflict for a particular matter. In doing so, the non conflicted Directors must act in a way they consider, in good faith, will be most likely to promote the success of the Company for the benefit of the shareholders as a whole.

The Directors (other than a Director acting in an executive capacity) are paid fees for their services. In total, these fees must not exceed £2,000,000 a year or any higher sum decided by an ordinary resolution at a general meeting of shareholders. In addition, special pay may be awarded to a Director who acts in an executive capacity, serves on a committee, performs services which the Directors consider to extend beyond the ordinary duties of a Director, devotes special attention to the business of National Grid, or goes or lives abroad on the Company’s behalf. Directors may also receive reimbursement for expenses properly incurred, and may be awarded pensions and other benefits. The compensation awarded to the Executive Directors is determined by the Remuneration Committee. Further details of Directors’ remuneration are set out in the Directors’ Remuneration Report (see pages 60 to 75).

The Directors may exercise all the powers of National Grid to borrow money. However, the aggregate principal amount of all the Group’s borrowings outstanding at any time must not exceed £35 billion or any other amount approved by shareholders by an ordinary resolution at a general meeting.

Directors can be appointed or removed by the Board or shareholders in a general meeting. Directors must stand for election at the first AGM following their appointment to the Board. Each Director must retire at least every three years, although they will be eligible for re-election. In accordance with best practice introduced by the UK Corporate Governance Code, all Directors wishing to continue in office currently offer themselves for re-election annually. No person is disqualified from being a Director or is required to vacate that office by reason of attaining a maximum age.

A Director is not required to hold shares in National Grid in order to qualify as a Director.

Rights, preferences and restrictions

(i) Dividend rights

National Grid may not pay any dividend otherwise than out of profits available for distribution under the Companies Act 2006 and other applicable provisions of English law. In addition, as a public company, National Grid may only make a distribution if, at the time of the distribution, the amount of its net assets is not less than the aggregate of its called up share capital and undistributable reserves (as defined in the Companies Act 2006) and to the extent that the distribution does not reduce the amount of those assets to less than that aggregate. Ordinary shareholders and ADS holders receive dividends.

Subject to these points, shareholders may, by ordinary resolution, declare dividends in accordance with the respective rights of the shareholders, but not exceeding the amount recommended by the Board. The Board may pay interim dividends if it considers that National Grid’s financial position justifies the payment. Any dividend or interest unclaimed for 12 years from the date when it was declared or became due for payment will be forfeited and revert to National Grid.

(ii) Voting rights

Subject to any rights or restrictions attached to any shares and to any other provisions of the Articles, at any general meeting on a show of hands, every shareholder who is present in person will have one vote and on a poll, every shareholder will have one vote for every share they hold. On a show of hands or poll, shareholders may cast votes either personally or by proxy. A proxy need not be a shareholder. Under the Articles, all substantive resolutions at a general meeting must be decided on a poll. Ordinary shareholders and ADS holders can vote at general meetings.

(iii) Liquidation rights

In a winding up, a liquidator may, in each case with the sanction of a special resolution passed by the shareholders and any other sanction required under English law, (a) divide among the shareholders the whole or any part of National Grid’s assets (whether the assets are of the same kind or not); the liquidator may, for this purpose, value any assets and determine how the division should be carried out as between shareholders or different classes of shareholders, or (b) transfer any part of the assets to trustees on trust for the benefit of the shareholders as the liquidator determines. In neither case will a shareholder be compelled to accept assets upon which there is a liability.

(iv) Restrictions

There are no restrictions on the transfer or sale of ordinary shares. Some of the Company’s employee share plans, details of which are contained in the Directors’ Remuneration Report, include restrictions on the transfer of shares while the shares are subject to the plan. Where, under an employee share plan operated by the Company, participants are the beneficial owners of the shares but not the registered owner, the voting rights may be exercised by the registered owner at the direction of the participant. Treasury shares do not attract a vote or dividends.

Variation of rights

Subject to applicable provisions of English law, the rights attached to any class of shares of National Grid may be varied or cancelled. This must be with the written consent of the holders of three quarters in nominal value of the issued shares of that class, or with the sanction of a special resolution passed at a separate meeting of the holders of the shares of that class.

		General meetings AGMs must be convened each year within six months of the Company’s accounting reference date upon 21 clear days’ advance written notice. Any other general meeting may be convened provided at least 14 clear days’ written notice is given, subject to annual approval of shareholders. In certain limited circumstances, the Company can convene a general meeting by shorter notice. The notice must specify, among other things, the nature of the business to be transacted, the place, the date and the time of the meeting. Rights of non residents There are no restrictions under National Grid’s Articles that would limit the rights of persons not resident in the UK to vote in relation to ordinary shares.
		Disclosure of interests Under the Companies Act 2006, National Grid may, by written notice, require a person whom it has reasonable cause to believe to be or to have been in the last three years interested in its shares to provide additional information relating to that interest. Under the Articles, failure to provide such information may result in a shareholder losing their rights to attend, vote or exercise any other right in relation to shareholders’ meetings. Under the UK Disclosure and Transparency Rules, there is also an obligation on a person who acquires or ceases to have a notifiable interest in shares in National Grid to notify the Company of that fact. The disclosure threshold is 3% and disclosure is required each time the person’s direct and indirect holdings reach, exceed or fall below each 1% threshold thereafter. The UK City Code on Takeovers and Mergers imposes strict disclosure requirements with regard to dealings in the securities of an offeror or offeree company, and also on their respective associates, during the course of an offer period. Other regulators in the UK, US and elsewhere may have, or assert, notification or approval rights over acquisitions or transfers of shares.

Depositary payments to the Company

The Depositary reimburses the Company for certain expenses it incurs in relation to the ADS programme. The Depositary also pays the standard out-of-pocket maintenance costs for the ADSs, which consist of the expenses for the mailing of annual and interim financial reports, printing and distributing dividend cheques, electronic filing of US federal tax information, mailing required tax forms, stationery, postage, facsimile and telephone calls. It also reimburses the Company for certain investor relationship programmes or special investor relations promotional activities. There are limits on the amount of expenses for which the Depositary will reimburse the Company, but the amount of reimbursement is not necessarily tied to the amount of fees the Depositary collects from investors. For the period 1 April 2014 to 20 May 2015, the Company received a total of $2,094,871.42 in reimbursements from the Depositary consisting of $1,440,230.53 and $654,640.89 received in October 2014 and January 2015 respectively. Fees that are charged on cash dividends will be apportioned between the Depositary and the Company, see below.

Any questions from ADS holders should be directed to The Bank of New York Mellon at the contact details on page 196.

Description of securities other than equity securities: depositary fees and charges

The Bank of New York Mellon, as the Depositary, collects fees, by deducting those fees from the amounts distributed or by selling a portion of distributable property, for:

● delivery and surrender of ADSs directly from investors depositing shares or surrendering ADSs for the purpose of withdrawal or from intermediaries acting for them; and

● making distributions to investors (including, it is expected, cash dividends).

The Depositary may generally refuse to provide fee attracting services until its fees for those services are paid.

The Company’s Deposit Agreement under which the ADS are issued allows a fee of up to $0.05 per ADS to be charged for any cash distribution made to ADS holders, including cash dividends. ADS holders who receive cash in relation to the 2014/15 final dividend will be charged a fee of $0.02 per ADS by the Depositary prior to distribution of the cash dividend.

On 20 April 2015, The Capital Group of Companies, Inc. notified us of a holding in voting rights of 3.881%, 145,094,617 ordinary shares, as at 16 April 2015. As at 20 May 2015, no further notifications have been received. The rights attached to ordinary shares are detailed on page 177. All ordinary shares carry the same voting rights. Share capital The share capital of the Company consists of ordinary shares of 11¹⁷⁄₄₃ pence nominal value each and ADSs, which represent five ordinary shares each. Authority to purchase shares Shareholder approval was given at the 2014 AGM to purchase up to 10% of the Company’s share capital (being 373,477,508 ordinary shares). The Directors intend to seek shareholder approval to renew this authority at this year’s AGM. In some circumstances, the Company may find it advantageous to have the authority to purchase its own shares in the market, where the Directors believe this would be in the interests of shareholders generally. The Directors believe that it is an important part of the financial management of the Company to have the flexibility to repurchase issued shares in order to manage its capital base, including actively managing share issuances from the operation of the scrip dividend scheme. It is expected that such repurchases will not exceed 2.5% of the issued share capital (excluding treasury shares) per annum. When purchasing shares, the Company have and will, take into account market conditions prevailing at the time, other investment and financing opportunities and the overall financial position of the Company. During the year the Company purchased ordinary shares in the capital of the Company as part of the management of the dilutive effect of share issuances under the scrip dividend scheme.				Authority to allot shares Shareholder approval was given at the 2014 AGM to allot shares of up to one third of the Company’s share capital. The Directors are seeking this same lower level of authority this year. The Directors consider that the Company will have sufficient flexibility with the lower level of authority to respond to market developments. This authority is in line with investor guidelines. The Directors currently have no intention of issuing new shares, or of granting rights to subscribe for or convert any security into shares, except in relation to, or in connection with, the operation and management of the Company’s scrip dividend scheme and the exercise of options under the Company’s share plans. No issue of shares will be made which would effectively alter control of the Company without the sanction of shareholders in general meeting. The Company expects to actively manage the dilutive effect of share issuance arising from the operation of the scrip dividend scheme. In some circumstances, additional shares may be allotted to the market for this purpose under the authority provided by this resolution. Under these unlikely circumstances, it is expected that the associated allotment of new shares (or rights to subscribe for or convert any security into shares) will not exceed 1% of the issued share capital (excluding treasury shares) per year. Dividend waivers The trustees of the National Grid Employees Share Trust, which are independent of the Company, waived the right to dividends paid during the year, and have agreed to waive the right to future dividends, in relation to the ordinary shares and American Depositary Receipts (ADR) held by the trust. Under the Company’s ADR programme, the right to dividends in relation to the ordinary shares underlying the ADRs was waived during the year by the ADR Depositary, under an arrangement whereby the Company pays the monies to satisfy any dividends separately to the Depositary for distribution to ADR holders entitled to the dividend. This arrangement is expected to continue for future dividends. Share price National Grid ordinary shares are listed on the London Stock Exchange under the symbol NG and the ADSs are listed on the New York Stock Exchange under the symbol NGG.

Price history The following table shows the highest and lowest intraday market prices for our ordinary shares and ADSs for the periods indicated:							This discussion is not a comprehensive description of all the US federal income tax and UK tax considerations that may be relevant to any particular investor (including consequences under the US alternative minimum tax or net investment income tax) and does not address state, local, or other tax laws. National Grid has assumed that shareholders, including US Holders, are familiar with the tax rules applicable to investments in securities generally and with any special rules to which they may be subject. This discussion deals only with US Holders who hold ADSs or ordinary shares as capital assets. It does not address the tax treatment of investors who are subject to special rules, such as: ● financial institutions; ● insurance companies; ● dealers in securities or currencies; ● investors who elect mark-to-market treatment; ● partnerships or other pass-through entities and their partners; ● individual retirement accounts and other tax-deferred accounts; ● tax-exempt organisations; ● investors who own (directly or indirectly) 10% or more of our voting stock; ● investors who hold ADSs or ordinary shares as a position in a straddle, hedging transaction or conversion transaction; and ● investors whose functional currency is not the US dollar. The statements regarding US and UK tax laws and administrative practices set forth below are based on laws, treaties, judicial decisions and regulatory interpretations in effect on the date of this document. These laws and practices are subject to change without notice, potentially with retroactive effect. In addition, the statements set forth below are based on the representations of the Depositary and assume that each party to the Deposit Agreement will perform its obligations thereunder in accordance with its terms. US Holders of ADSs will be treated as the owners of the ordinary shares represented by those ADSs for US federal income tax purposes. For the purposes of the Tax Convention, the Estate Tax Convention and UK tax considerations, this discussion assumes that a US Holder of ADSs will be treated as the owner of the ordinary shares represented by those ADSs. HMRC has stated that it will continue to apply its long-standing practice of treating a holder of ADSs as holding the beneficial interest in the ordinary shares represented by the ADSs; however, we note that this is an area of some uncertainty and may be subject to change. US Holders should consult their own advisors regarding the tax consequences of buying, owning and disposing of ADSs or ordinary shares in light of their particular circumstances, including the effect of any state, local, or other tax laws. Taxation of dividends The UK does not currently impose a withholding tax on dividends paid to US Holders. Cash distributions paid out of our current or accumulated earnings and profits (as determined for US federal income tax purposes) generally will be taxable to a US Holder as dividend income. Distributions in excess of current and accumulated earnings and profits will be treated as a non-taxable return of capital to the extent of a US Holder’s basis in its ADSs or ordinary shares, as applicable, and thereafter as a capital gain. However, we do not maintain calculations of our earnings and profits in accordance with US federal income tax principles. US Holders should therefore assume that any distribution by us with respect to ADSs or ordinary shares will be reported as dividend income.

Taxation The discussion in this section provides information about certain US federal income tax and UK tax consequences for US Holders (defined below) of owning ADSs and ordinary shares. A US Holder is beneficial owner of ADSs or ordinary shares that: ● is (i) an individual citizen or resident of the United States, (ii) a corporation created or organised under the laws of the United States, any State thereof or the District of Columbia, (iii) an estate the income of which is subject to US federal income tax without regard to its source or (iv) a trust if a court within the United States is able to exercise primary supervision over the administration of the trust and one or more US persons have the authority to control all substantial decisions of the trust, or the trust has elected to be treated as a domestic trust for US federal income tax purposes; ● is not resident or ordinarily resident in the UK for UK tax purposes; and ● does not hold ADSs or ordinary shares in connection with the conduct of a business or the performance of services in the UK or otherwise in connection with a branch, agency or permanent establishment in the UK.


182

Dividends received by non-corporate US Holders with respect to ADSs or ordinary shares will generally be taxable at the reduced rate applicable to long-term capital gains provided (i) either (a) we are eligible for the benefits of the Tax Convention or (b) ADSs or ordinary shares are treated as ‘readily tradable’ on an established securities market in the United States and (ii) we are not, for our taxable year during which the dividend is paid or the prior year, a passive foreign investment company for US federal income tax purposes (a PFIC), and certain other requirements are met. We (1) expect that our shares will be treated as ‘readily tradable’ on an established securities market in the United States as a result of the trading of ADSs on the New York Stock Exchange and (2) believe we are eligible for the benefits of the Tax Convention. Based on our audited financial statements and the nature of our business activities, we believe that we were not treated as a PFIC for US federal income tax purposes with respect to our taxable year ending 31 March 2015. In addition, based on our current expectations regarding the value and nature of our assets, the sources and nature of our income, and the nature of our business activities, we do not anticipate becoming a PFIC in the foreseeable future.

Dividends received by corporate US Holders with respect to ADSs or ordinary shares will not be eligible for the dividends received deduction generally allowed to corporations.

Taxation of capital gains

US Holders will not be subject to UK taxation on any capital gain realised on the sale or other disposition of ADSs or ordinary shares.

Provided that we are not a PFIC for any taxable year during which a US Holder holds their ADSs or ordinary shares, upon a sale or other disposition of ADSs or ordinary shares, a US Holder generally will recognise capital gain or loss equal to the difference between the US dollar value of the amount realised on the sale or other disposition and the US Holder’s adjusted tax basis in the ADSs or ordinary shares. Such capital gain or loss generally will be long-term capital gain or loss if the ADSs or ordinary shares were held for more than one year. For non-corporate US Holders, long-term capital gain is generally taxed at a lower rate than ordinary income. A US Holder’s ability to deduct capital losses is subject to significant limitations.

UK stamp duty and stamp duty reserve tax (SDRT)

Transfers of ordinary shares – SDRT at the rate of 0.5% of the amount or value of the consideration will generally be payable on any agreement to transfer ordinary shares that is not completed using a duly stamped instrument of transfer (such as a stock transfer form).

Where an instrument of transfer is executed and duly stamped before the expiry of the six year period beginning with the date on which the agreement is made, the SDRT liability will be cancelled. If a claim is made within the specified period, any SDRT which has been paid will be refunded. SDRT is due whether or not the agreement or transfer is made or carried out in the UK and whether or not any party to that agreement or transfer is a UK resident.

Purchases of ordinary shares completed using a stock transfer form will generally result in a UK stamp duty liability at the rate of 0.5% (rounded up to the nearest £5) of the amount or value of the consideration. Paperless transfers under the CREST paperless settlement system will generally be liable to SDRT at the rate of 0.5%, and not stamp duty. SDRT is generally the liability of the purchaser and UK stamp duty is usually paid by the purchaser or transferee.

Transfers of ADSs – No UK stamp duty will be payable on the acquisition or transfer of existing ADSs or beneficial ownership of ADSs, provided that any instrument of transfer or written agreement to transfer is executed outside the UK and remains at all times outside the UK.

An agreement for the transfer of ADSs in the form of ADRs will not result in a SDRT liability. A charge to stamp duty or SDRT may arise on the transfer of ordinary shares to the Depositary or The Bank of New York Mellon as agent of the Depositary (the Custodian).

The rate of stamp duty or SDRT will generally be 1.5% of the value of the consideration or, in some circumstances, the value of the ordinary shares concerned. However, there is no 1.5% SDRT charge on the issue of ordinary shares (or, where it is integral to the raising of new capital, the transfer of ordinary shares) to the Depositary or the Custodian.

The Depositary will generally be liable for the stamp duty or SDRT. Under the terms of the Deposit Agreement, the Depositary will charge any tax payable by the Depositary or the Custodian (or their nominees) on the deposit of ordinary shares to the party to whom the ADSs are delivered against such deposits. If the stamp duty is not a multiple of £5, the duty will be rounded up to the nearest multiple of £5.

US information reporting and backup withholding tax

Dividend payments made to US Holders and proceeds paid from the sale, exchange, redemption or disposal of ADSs or ordinary shares to US Holders may be subject to information reporting to the US Internal Revenue Service (IRS). Such payments may be subject to backup withholding taxes unless the holder (i) is a corporation or other exempt recipient or (ii) provides a taxpayer identification number on a properly completed IRS Form W-9 and complies with applicable certification requirements.

US Holders should consult their tax advisors about these rules and any other reporting obligations that may apply to the ownership or disposition of ADSs or ordinary shares, including reporting requirements related to the holding of certain foreign financial assets.

UK inheritance tax

An individual who is domiciled in the US for the purposes of the Estate Tax Convention and who is not a UK national for the purposes of the Estate Tax Convention will generally not be subject to UK inheritance tax in respect of (i) the ADSs or ordinary shares on the individual’s death or (ii) a gift of the ADSs or ordinary shares during the individual’s lifetime. This is not the case where the ADSs or ordinary shares are part of the business property of the individual’s permanent establishment in the UK or relate to a fixed base in the UK of an individual who performs independent personal services.

Special rules apply to ADSs or ordinary shares held in trust. In the exceptional case where the ADSs or shares are subject both to UK inheritance tax and to US federal gift or estate tax, the Estate Tax Convention generally provides for the tax paid in the UK to be credited against tax paid in the US.

Capital gains tax (CGT) for UK resident shareholders

All-employee share plans The all-employee share plans allow UK- or US-based employees to participate in either HMRC (UK) or Internal Revenue Service (US) approved plans and to become shareholders in National Grid. Sharesave Employees resident in the UK are eligible to participate in the Sharesave plan. Under this plan, participants may contribute between £5 and £500 in total each month, for a fixed period of three years, five years or both. Contributions are taken from net salary. SIP Employees resident in the UK are eligible to participate in the SIP. Contributions up to £150 are deducted from participants’ gross salary and used to purchase ordinary shares in National Grid each month. The shares are placed in trust. US Incentive Thrift Plans Employees of National Grid’s US companies are eligible to participate in the Thrift Plans, which are tax-advantaged savings plans (commonly referred to as 401(k) plans). They are DC pension plans that give participants the opportunity to invest up to applicable federal salary limits. The federal limits for calendar year 2014 are: for pre-tax contributions a maximum of 50% of salary limited to $17,500 for those under the age of 50 and $23,000 for those age 50 and above; for post-tax contributions, up to 15% of salary. The total amount of employee contributions (pre-tax and post-tax) may not exceed 50% of compensation and are further subject to the combined federal annual contribution limit of $52,000. For calendar year 2015, participants may invest up to the applicable federal salary limits: for pre-tax contributions a maximum of 50% of salary limited to $18,000 for those under the age of 50 and $24,000 for those age 50 and above; for post-tax contributions up to 15% of salary. The total amount of employee contributions (pre-tax and post-tax) may not exceed 50% of compensation and are further subject to the combined federal annual contribution limit of $53,000. ESPP Employees of National Grid’s US companies are eligible to participate in the ESPP (commonly referred to as a 423(b) plan). Eligible employees have the opportunity to purchase ADSs on a monthly basis at a 15% discounted price. Under the plan employees may contribute up to 20% of base pay each year up to a maximum annual contribution of $18,888 to purchase ADSs in National Grid. Change of control provisions No compensation would be paid for loss of office of Directors on a change of control of the Company. As at 31 March 2015, the Company had undrawn borrowing facilities with a number of its banks of £1.4 billion available to it and a further £630 million of drawn bank loans which, on a change of control of the Company following a takeover bid, may alter or terminate. All the Company’s share plans contain provisions relating to a change of control. Outstanding awards and options would normally vest and become exercisable on a change of control, subject to the satisfaction of any performance conditions at that time. In the event of a change of control of the Company, a number of governmental and regulatory consents or approvals are likely to be required arising from laws or regulations of the UK, US or the EU. Such consents or approvals may also be required for acquisitions of equity securities that do not amount to a change of control. No other agreements that take effect, alter or terminate upon a change of control of the Company following a takeover bid are considered to be significant in terms of their potential impact on the business as a whole.				Code of Ethics In accordance with US legal requirements, the Board has adopted a Code of Ethics for senior financial professionals. This code is available on our website (where any amendments or waivers will also be posted). There were no amendments to, or waivers of, our Code of Ethics during the year. Conflicts of interest The Board continues to monitor and note possible conflicts of interest that each Director may have. The Directors are regularly reminded of their continuing obligations in relation to conflicts, and are required annually to review and confirm their external interests. Potential conflicts are considered and, if appropriate, authorised. During the year ended 31 March 2015, the Board has been advised by the Directors of two actual conflicts of interest and has authorised these conflicts in accordance with its powers as set out in the Articles. The Board has also considered and noted a number of situations in relation to which no actual conflict of interest was identified. Corporate governance practices: differences from New York Stock Exchange (NYSE) listing standards The Company is listed on the NYSE and is therefore required to disclose differences in its corporate governance practices adopted as a UK listed company, compared with those of a US company. The corporate governance practices of the Company are primarily based on the requirements of the UK Corporate Governance Code (the Code) but substantially conform to those required of US companies listed on the NYSE. The following is a summary of the significant ways in which the Company’s corporate governance practices differ from those followed by US companies under Section 303A Corporate Governance Standards of the NYSE. • The NYSE rules and the Code apply different tests for the independence of Board members. • The NYSE rules require a separate nominating/corporate governance committee composed entirely of independent Directors. There is no requirement for a separate corporate governance committee in the UK. Under the Company’s corporate governance policies, all Directors on the Board discuss and decide upon governance issues and the Nominations Committee makes recommendations to the Board with regard to certain of the responsibilities of a corporate governance committee. • The NYSE rules require listed companies to adopt and disclose corporate governance guidelines. While the Company reports compliance with the Code in each Annual Report and Accounts, the UK requirements do not require the Company to adopt and disclose separate corporate governance guidelines. • The NYSE rules require a separate audit committee composed of at least three independent members. While the Company’s Audit Committee exceeds the NYSE’s minimum independent Non-executive Director membership requirements, it should be noted that the quorum for a meeting of the Audit Committee, of two independent Non-executive Directors, is less than the minimum membership requirements under the NYSE rules. • The NYSE rules require a compensation committee composed entirely of independent Directors, and prescribe criteria to evaluate the independence of the committee’s members and its ability to engage external compensation advisors. While the Code prescribes different independence criteria, the Non-executive Directors on the Remuneration Committee have each been deemed independent by the Board under the NYSE rules. Although the evaluation criteria for appointment of external advisors differ under the Code, the Remuneration Committee is solely responsible for appointment, retention and termination of such advisors.

Directors’ indemnity The Company has arranged, in accordance with the Companies Act 2006 and the Articles, qualifying third-party indemnities against financial exposure that Directors may incur in the course of their professional duties. Equivalent qualifying third-party indemnities were, and remain, in force for the benefit of those Directors who stood down from the Board during the year ended 31 March 2015. Alongside these indemnities, the Company places Directors’ and Officers’ liability insurance cover for each Director. Employees We negotiate with recognised unions. It is our policy to maintain well developed communications and consultation programmes and there have been no material disruptions to our operations from labour disputes during the past five years. National Grid believes that it can conduct its relationships with trade unions and employees in a satisfactory manner. Human Rights Respect for human rights is incorporated into our employment practices and our values, which include respecting others and valuing diversity. ‘Always Doing the Right Thing’ is our guide to ethical business conduct – the way in which we conduct ourselves allows us to build trust with the people we work with. We earn this trust by doing things in the right way, building our reputation as an ethical company that our stakeholders want to do business with, and that our employees want to work for. Although we do not have a specific policy relating to human rights, our procurement policies integrate sustainability into the way we do business throughout our supply chain, so that we create value, preserve natural resources and respect the interests of the communities we serve and from which we procure goods and services. Through our Global Supplier Code of Conduct, we expect our suppliers to keep to all laws relating to their business, as well as adhere to the principles of the United Nations Global Compact, the United Nations Declaration of Human Rights and the International Labour Organization. Listing Rule 9.8.4 R cross reference table Information required to be disclosed by LR 9.8.4 R (starting on page indicated):		member of National Grid has any obligation or entitlement which is material to National Grid at the date of this Report. Political donations and expenditure National Grid made no donations in the UK or EU during the year, including donations as defined for the purposes of the Political Parties, Elections and Referendums Act 2000. National Grid USA and its affiliated New York and federal political action committees (each, a PAC) made political donations in the US totalling $54,375 (£34,415) during the year. National Grid USA’s affiliated New York PAC was funded partly by contributions from National Grid USA and certain of its subsidiaries and partly by voluntary employee contributions. National Grid USA’s affiliated federal PAC was funded wholly by voluntary employee contributions. Property, plant and equipment This information can be found under the heading note 11 property, plant and equipment on page 115, note 19 Borrowings on pages 123 and 124, Strategic Report pages 08 to 11, where we operate on page 165 and principal operations on pages 27 to 36. Research and development Expenditure on research and development during the year was £23 million (2013/14: £12 million; 2012/13: £15 million). Innovation funding throughout 2014/15 has stimulated greater investment across all three of our UK Regulated business areas: UK ET, UK GT and UK GD. Delivering benefits for our stakeholders has been at the forefront of each of our Innovation Projects. This has driven collaboration across the industry in search of new techniques to revolutionise the way we work. Due to the way in which we work with a large number of partners on new ideas, our disclosed research and development expenditure is lower than the overall contribution we make to the industry. We only disclose directly incurred expenditure, and not those amounts our partners incur working on projects with us. The UK ET innovation portfolio has developed to reflect the evolution of our strategic innovation priorities. Our activities in the year have focused on enhancing our capabilities in managing ageing assets, improving the efficiency of new build, and system reliability and availability. In addition NGET secured £6.9 million of funding to develop new approaches to frequency control. The UK GT innovation portfolio has developed and expanded over the past year to include projects on 3D modelling, virtual reality technologies and sustainable energy solutions. In addition, GT won £5.7 million of funding for industry leading work in robotics for Project GRAID (Gas Robotic Agile Inspection Device). Innovation in UK GD has focused on reduction of leakage levels and minimisation of street works and excavations through the use of robotics. Our customers have been central to our portfolio, with projects enhancing safety through the use of Intelligent Carbon Monoxide monitoring and more robust on-site fencing feet and projects improving real-time information for work on-site through the use of QR codes. The US business has been working on research and development initiatives to improve the way we deliver gas operations, and on modernising the US electricity grid in Massachusetts and Reforming the Energy Vision (REV) in New York State. More information in relation to grid modernisation and REV can be found on page 170. Unresolved SEC staff comments There are no unresolved staff comments required to be reported.

		Reconciliations of adjusted profit measures

Use of adjusted profit measures

In considering the financial performance of our businesses and segments, we analyse each of our primary financial measures of operating profit, profit before tax, profit for the year attributable to equity shareholders and EPS into two components.

The first of these components is referred to as an adjusted profit measure, also known as a business performance measure. This is the principal measure used by management to assess the performance of the underlying business.

Adjusted results exclude exceptional items, remeasurements and stranded cost recoveries. These items are reported collectively as the second component of the financial measures. Note 4 on page 103 explains in detail the items which are excluded from our adjusted profit measures.

Adjusted profit measures have limitations in their usefulness compared with the comparable total profit measures as they exclude important elements of our financial performance. However, we believe that by presenting our financial performance in two components it is easier to read and interpret financial performance between periods, as adjusted profit measures are more comparable having removed the distorting effect of the excluded items. Those items are more clearly understood if separately identified and analysed.

The presentation of these two components of financial performance is additional to, and not a substitute for, the comparable total profit measures presented.

Management uses adjusted profit measures as the basis for monitoring financial performance and in communicating financial performance to investors in external presentations and announcements of financial results.

Internal financial reports, budgets and forecasts are primarily prepared on the basis of adjusted profit measures, although planned exceptional items, such as significant restructurings, are also reflected in budgets and forecasts. We separately monitor and disclose the excluded items as a component of our overall financial performance.

Analysis of the adjusted operating profit by segment for the year ended 31 March 2014

UK Electricity Transmission

For the year ended 31 March 2014, revenue in the UK Electricity Transmission segment increased by £277 million, and adjusted operating profit increased by £38 million.

Net regulated income after pass-through costs was £170 million higher, reflecting increases in allowed revenues under the new RIIO regulatory framework. This was partially offset by under-recoveries of revenue in the year of £60 million compared with over-recoveries of £29 million in the prior year. Regulated controllable costs were £27 million higher due to inflation, legal fees and one-off credits in the prior year. Depreciation and amortisation was £20 million higher reflecting the continued capital investment programme (investment in the year was £1,381 million). Other costs were £4 million lower than prior year.

UK Gas Transmission

Revenue in the UK Gas Transmission segment decreased by £177 million in 2013/14 to £941 million and adjusted operating profit fell by £114 million to £417 million.

Net regulated income after pass-through costs was £80 million lower, with lower permit income than prior year under the new RIIO arrangements. In addition, under-recoveries in the year of £21 million compared with over-recoveries last year of £17 million, gave rise to an adverse timing movement of £38 million. Depreciation and amortisation was £10 million higher due to investment, with £181 million invested in the year. Partially offsetting these, other operating costs were £14 million lower.

UK Gas Distribution

UK Gas Distribution revenue increased by £184 million in the year to £1,898 million, and adjusted operating profit increased by £110 million to £904 million.

Net regulated income after pass-through costs was £96 million higher, reflecting increases in allowed revenues under the new RIIO regulatory framework. Timing differences added another £39 million, with £29 million over-recoveries in 2013/14, compared with a £10 million under-recovery in the prior year. Partially offsetting these, regulated controllable costs were £14 million higher primarily due to inflation. Depreciation and amortisation was £10 million higher reflecting the continued capital investment programme (investment in the year was £480 million). Other costs were £1 million higher than prior year.

US Regulated

Revenue in our US Regulated businesses was £122 million higher at £8,040 million, and adjusted operating profit fell by £129 million to £1,125 million.

The weaker dollar reduced operating profit in the year by £38 million. Excluding the impact of foreign exchange, net regulated income fell by £52 million, principally due to the end of deferral income recoveries at Niagara Mohawk in March 2013. Timing differences added another £29 million profit compared with prior year. Regulated controllable costs increased by £89 million at constant currency as a result of inflation and wage increases, higher insurance costs post Superstorm Sandy, and cost true-ups identified during the implementation of the new enterprise resource planning system. Other operating costs (excluding major storms) increased by £61 million at constant currency due to the higher cost of non-major storm remediation, higher property taxes and depreciation of the new US enterprise resource planning system.

There were no major storms affecting our operations in the year ended 31 March 2014. In 2012/13, two major storms in the US, Superstorm Sandy and Storm Nemo, reduced operating profit within US Regulated by £82 million at constant currency.

Our capital investment programme continued in the US, with a further £1,219 million invested in 2013/14.

Other activities

Revenue in Other activities increased by £58 million to £736 million in the year ended 31 March 2014. Adjusted operating profit was £120 million higher at £131 million.

There was no repeat of the major storm cost of £51 million incurred in our insurance captive in the prior year due to Superstorm Sandy. Operating profit in the French interconnector was £62 million higher as a result of strong auction revenues this year. In our other non-regulated businesses, adjusted operating profit was £7 million higher due to improved results in our UK metering business and insurance captive, partially offset by higher costs associated with the stabilisation of the new US enterprise resource planning system.

Capital expenditure in our Other activities was £37 million lower at £180 million, principally reflecting reduced capital spend on the new US enterprise resource planning system.

Analysis of the statement of financial position for the year ended 31 March 2014

Goodwill and other intangible assets

Goodwill and intangibles decreased by £354 million to £5,263 million as at 31 March 2014. This decrease was due to foreign exchange movements of £472 million and software amortisation of £127 million, partially offset by software additions of £179 million.

Property, plant and equipment

Property, plant and equipment increased by £587 million to £37,179 million as at 31 March 2014. This was due to capital expenditure of £3,262 million on the renewal and extension of our regulated networks, offset by foreign exchange movements of £1,244 million, and £1,299 million of depreciation in the year.

Investments and other non-current assets

Investments in joint ventures and associates; financial and other investments and other non-current assets decreased by £31 million to £722 million as at 31 March 2014. This was principally due to changes in the fair value of our US commodity contract assets and available-for-sale investments.

Inventories and current intangible assets, and trade and other receivables

Inventories and current intangible assets, and trade and other receivables decreased by £78 million to £3,123 million as at 31 March 2014. This decrease was principally due to foreign exchange movements of £195 million, partially offset by an increase in trade and other receivables of £120 million mostly due to colder weather in the US in February and March 2014 compared with 2013 resulting in increased billings for commodity costs and customer usage.

Trade and other payables

Trade and other payables decreased by £20 million to £3,031 million as at 31 March 2014 due to favourable foreign exchange movements of £150 million, partially offset by higher payables in the UK due in part to changes in payment terms with new Gas Distribution strategic partners and increased activity on the Western Link project.

Current tax liabilities

Current tax liabilities decreased by £63 million to £168 million at 31 March 2014. This was primarily due to higher tax payments made in 2013/14 although these were partially offset by a larger current tax charge.

Deferred tax liabilities

Deferred tax liabilities increased by £5 million to £4,082 million as at 31 March 2014. This was primarily due to the impact of the £172 million deferred tax charge on actuarial gains (a £179 million tax credit in 2012/13) being offset by the impact of the reduction in the UK statutory tax rate for future periods, foreign exchange movements and the reduction in prior year charges.

Provisions and other non-current liabilities

Provisions (both current and non-current) and other non-current liabilities decreased by £158 million to £3,486 million as at 31 March 2014.

Total provisions decreased by £115 million to £1,645 million as at 31 March 2014. The underlying movements included additions of £230 million primarily relating to a provision for the demolition of certain gas holders in the UK of £79 million, restructuring provisions of £86 million and other provisions of £42 million, more than offset by foreign exchange movements of £112 million and utilisation of £288 million in relation to all classes of provisions.

Other non-current liabilities decreased by £43 million principally due to foreign exchange movements of £47 million.

Net debt

Net debt is the aggregate of cash and cash equivalents, current financial and other investments, borrowings, and derivative financial assets and liabilities.

Net pension and other post-retirement obligations

A summary of the total UK and US assets and liabilities and the overall net IAS 19 (revised) accounting deficit is shown below:


Net plan liability	UK £m		US £m		Total £m
As at 1 April 2013	(1,169	)	(2,328	)	(3,497)

Plan liabilities	(18,162	)	(7,507	)	(25,669)
	(753	)	(1,658	)	(2,411)

The principal movements in net obligations during the year included a curtailment gain of £214 million following the LIPA MSA transition, net actuarial gains of £485 million and employer contributions of £596 million. Net actuarial gains included actuarial gains on plan liabilities of £542 million arising as a consequence of an increase in the UK real discount rate and the nominal discount rate in the US. This was partially offset by actuarial losses of £283 million arising from increases in life expectancy in the US. Actuarial losses/gains on plan assets reflects the asset allocations in the different plans. In both the UK and US, returns on equities were above the assumed rate; however, UK Government securities had negative returns and corporate bonds were close to nil.

The Directors’ Report, comprising pages 06 to 75 and 164 to 191, has been drawn up in accordance with the requirements of English law, and liability in respect thereof is also governed by English law. In particular, the liability of the Directors for these reports is solely to National Grid.

This document contains certain statements that are neither reported financial results nor other historical information. These statements are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These statements include information with respect to our financial condition, our results of operations and businesses, strategy, plans and objectives.

These forward-looking statements are not guarantees of our future performance and are subject to assumptions, risks and uncertainties that could cause actual future results to differ materially from those expressed in or implied by such forward-looking statements. Many of these assumptions, risks and uncertainties relate to factors that are beyond our ability to control or estimate precisely, such as changes in laws or regulations, announcements from and decisions by governmental bodies or regulators (including the timeliness of consents for construction projects); the timing of construction and delivery by third parties of new generation projects requiring connection; breaches of, or changes in, environmental, climate change and health and safety laws or regulations, including breaches or other incidents arising from the potentially harmful nature of our activities; network failure or interruption, the inability to carry out critical non network

operations and damage to infrastructure, due to adverse weather conditions including the impact of major storms as well as the results of climate change, due to counterparties being unable to deliver physical commodities, or due to the failure of or unauthorised access to or deliberate breaches of our IT systems and supporting technology; performance against regulatory targets and standards and against our peers with the aim of delivering stakeholder expectations regarding costs and efficiency savings, including those related to investment programmes and internal transformation and remediation plans; and customers and counterparties (including financial institutions) failing to perform their obligations to the Company. Other factors that could cause actual results to differ materially from those described in this document include fluctuations in exchange rates, interest rates and commodity price indices; restrictions and conditions (including filing requirements) in our borrowing and debt arrangements, funding costs and access to financing; regulatory requirements for us to maintain financial resources in certain parts of our business and restrictions on some subsidiaries’ transactions such as paying dividends, lending or levying charges; inflation or deflation; the delayed timing of recoveries and payments in our regulated businesses and whether aspects of our activities are contestable; the funding requirements and performance of our pension schemes and other post-retirement benefit schemes; the failure to attract, train or retain employees with the necessary competencies, including leadership skills, and any significant disputes arising with our employees or the breach of laws or regulations by our employees; and the failure to respond to market developments, including competition for onshore transmission, and grow our business to deliver our strategy, as well as incorrect or unforeseen assumptions or conclusions (including unanticipated costs and liabilities) relating to business development activity, including assumptions in connection with joint ventures.

For further details regarding these and other assumptions, risks and uncertainties that may affect National Grid, please read the Strategic Report and the Risk factors on pages 173 and 176 of this document. In addition, new factors emerge from time to time and we cannot assess the potential impact of any such factor on our activities or the extent to which any factor, or combination of factors, may cause actual future results to differ materially from those contained in any forward-looking statement. Except as may be required by law or regulation, the Company undertakes no obligation to update any of its forward-looking statements, which speak only as of the date of this document.
