DIRECTOR NOMINEES – DIVERSITY OF SKILLS AND EXPERIENCE

The Nominating and Governance Committee identifies, reviews, and recommends nominees to the Board for approval. The Committee seeks individuals with distinguished records of leadership and success and who will make substantial contributions to Board operations and effectively represent the interests of all stockholders. The Committee considers a wide range of factors and experiences, including ensuring an experienced, qualified Board with expertise in the following key areas most relevant to 3M. The numbers indicated in the diagram below represent the number of director nominees who the Committee believes possess each of the skills and experiences.

Significant Corporate Governance Actions

We recently implemented several changes that demonstrate our ongoing commitment to strong corporate governance practices:

Board Refreshment

We regularly add directors to infuse new ideas and fresh perspectives into the boardroom. In the past five years, six new independent directors have joined our Board. In recruiting directors, we focus on how the experience and skill set of each individual complements those of their fellow directors to create a balanced board with diverse viewpoints and backgrounds, deep expertise, and strong leadership experience. At the Annual Meeting, two nominees will be standing for election to the board for the first time. Dr. Dambisa Moyo, who joined the Board in August 2018, holds a doctorate in economics from the University of Oxford and has expertise in examining the interplay of international business and the global economy. Her background includes advising companies in their investment decisions, capital allocation and risk management. Prior to founding Mildstorm LLC, she worked at Goldman Sachs in various roles, including as an economist, and at the World Bank in Washington, D.C. The combination of her banking and financial services industry experience along with her extensive knowledge of macroeconomics, geopolitics and global markets brings valuable insight to the 3M Board. A new nominee, Pamela J. Craig, is the retired Chief Financial Officer of Accenture plc, a global management consulting, technology services and outsourcing company. She served as Accenture's CFO from 2006 through 2013, following her many other leadership roles at Accenture during her 34 years with the company. Her experience as CFO at a global Fortune 500 company, and her skills in financial, audit, risk management, and governance matters, adds valuable expertise to the 3M Board.

Stockholder Outreach and Engagement

Stockholder engagement is fundamental to our commitment to good governance and essential to maintaining our strong corporate governance practices. We engage regularly with our global investors to gain valuable insights into the governance issues about which they care most. We aim to seek a collaborative and mutually beneficial approach to issues of importance to investors that affect our business, and to ensure that our corporate governance practices remain industry-leading from their perspectives.

During 2018, members of senior management met with a cross-section of stockholders owning approximately 36 percent of our outstanding shares or approximately 55 percent of our institutional stockholders. The meetings included an overview of the Company and a discussion of the Company’s practices on corporate governance, including board refreshment and diversity, director evaluation, directors’ skills matrix, sustainability, succession planning, and board leadership structure. In general, investors viewed the Company’s governance practices favorably, including the Board’s leadership structure, the mix of tenure and overall diversity, and the disclosure regarding the Directors’ skill sets and qualifications. The feedback from these meetings was shared with the Board of Directors and helped inform the Board on corporate governance practices and trends. Although stockholder engagement is primarily a function of management, our lead independent director and executive chairman attended some of these meetings.

PROPOSAL

Ratification of the Appointment of Independent Registered Public Accounting Firm for 2019 ●Ratify the appointment of PricewaterhouseCoopers LLP as 3M’s independent registered public accounting firm for 2019. ●Based on its assessment of the qualifications and performance of PricewaterhouseCoopers LLP (“PwC”), the Audit Committee believes that it is in the best interests of the Company and its stockholders to retain PwC.

PROPOSAL

2018 Financial Performance and Business Highlights

3M’s 2018 financial performance was achieved through growth and disciplined execution. Given the impact that certain events had on the Company’s 2018 financial performance, our results are shown below both as determined in accordance with GAAP (to the extent applicable) and excluding the following: (1) a charge primarily related to the remeasurement of a transition tax under the Tax Cuts and Jobs Act of 2017 (referred to as the “TCJA”) on previously unremitted earnings of non-U.S. subsidiaries, net of remeasurement of 3M’s deferred tax assets and liabilities considering the TCJA’s newly enacted tax rates and other impacts

(referred to as the “Net TCJA Transition Tax”), (2) an $897 million ($770 million after-tax) charge related to the settlement of the previously disclosed Nature Resource Damages (NRD) lawsuit, including (a) $850 million for a grant to the State of Minnesota for a special “3M Grant for Water Quality and Sustainability Fund,” and (b) certain legal fees and other related obligations, and (3) the gains from the divestiture of substantially all of our Communication Markets Division, net of related actions (referred to as the “Net CMD Divestiture Gains”).

		Results Determined in Accordance with GAAP (to the Extent Applicable)		Results Excluding Impact of U.S. Tax Reform, the Net CMD Divestiture Gains and the Water Quality and Sustainability Grant
Earnings Per Share Growth		+12.1%		+8.6%*		●Excluding the impact of the Net TCJA Transition Tax, the Net CMD Divestiture Gains and the Water Quality and Sustainability Grant, earnings per share grew from $9.17 in 2017 to $9.96 in 2018. ●Excluding the impact of the Water Quality and Sustainability Grant and the Net CMD Divestiture Gains, full-year underlying operating margin performance was 23.6% in 2018.
Organic Local Currency Sales Growth		+3.2%		+3.2%		●Positive organic growth across all Business Groups and geographic areas.

See Appendix A to this Proxy Statement for a reconciliation of earnings per share, operating margin performance, free cash flow and free cash flow conversion to our results for the most directly comparable financial measures as reported under generally accepted accounting principles in the United States, and the calculation of return on invested capital.

We believe that our ability to deliver consistent results over time is reflected in our total stockholder return, which was in the top half of our executive compensation peer group for the three- and five-year periods ending on December 31, 2018. For additional information, see “Total Stockholder Return” on page 50 of this Proxy Statement.

Other noteworthy accomplishments include the following:

●	Announced the acquisition of M*Modal to strengthen our Health Information Systems portfolio and complement organic growth;
●	Awarded a record total of 4,208 patents from patent offices around the world in 2018, including 688 patents granted to 3M by the United States Patent and Trademark Office, which brings to more than 117,000 the total number of patents awarded to 3M in its corporate history;
●	Strengthened our portfolio going forward by completing the divestiture of substantially all of our Communication Markets Division;
●	Successfully completed the rollout of the enterprise resource planning (ERP) system in the United States – approximately 70 percent of global revenues are now on the new ERP system;
●	Over 100 consecutive years of paying dividends to stockholders and 60 consecutive years of annual increases;

Elements of Target 2018 Total Direct Compensation

The illustration below and the discussion that follows show how the target Total Direct Compensation of the Named Executive Officers (excluding our Executive Chairman) was apportioned among base salary, annual incentives, performance share awards and stock options for 2018, and how these elements relate to the strategic business goals of the Company.

Abbreviations: AIP = Annual incentive pay; PSAs = Performance share awards.
*	Amounts shown represent the apportionment of Total Direct Compensation for Mr. Roman.
**	Amounts shown reflect the average apportionment for all Named Executive Officers other than Mr. Roman and Mr. Thulin. Including Mr. Thulin, the average apportionment for the other Named Executive Officers would be as follows: base salary — 13 percent; AIP — 14 percent; stock options — 40 percent; performance shares — 34 percent; and performance-based pay — 85 percent. Note: Numbers do not add to 100 percent due to rounding.

Compensation Policies and Practices

Our compensation program is designed to provide appropriate performance incentives and avoid compensation practices that do not promote the interests of our stockholders.

	✓Maintain a strong alignment between corporate performance and our executive officers’ compensation by having a majority of Total Direct Compensation consist of performance-based compensation. ✓Conduct an annual assessment for the purpose of identifying and mitigating significant economic and reputational risks in the design of our incentive compensation programs. ✓Have a comprehensive clawback policy that covers both cash and equity compensation and includes provisions addressing reputational and financial risk as well as risk management failures. ✓Use an independent compensation consultant retained by, and reporting directly to, the Committee. ✓Limit the number and amount of executive perquisites. ✓Prohibit our executive officers from hedging or pledging 3M common stock. ✓Maintain robust stock ownership guidelines applicable to all of our executive officers. ✓Conduct competitive benchmarking to align executive compensation with the market.
	✕Have employment, severance, or change in control agreements with any of our executive officers. ✕Provide tax gross-ups on executive perquisites. ✕Have agreements that would provide automatic “single-trigger” accelerated vesting of equity compensation or excise tax gross-up payments to any of our executive officers upon a change in control. ✕Pay dividends or dividend equivalents on unearned equity awards. ✕Reprice stock options without the approval of 3M stockholders, except for “anti-dilution” adjustments (such as adjustments in connection with a stock split, spinoff, etc.)

Noteworthy Compensation Actions for 2018

During 2018, 3M and the Committee took the noteworthy actions described below as part of the Company’s executive compensation program.

●	Approved new compensation terms for Michael F. Roman in connection with his appointment as Chief Executive Officer, including an annual base salary of $1,200,000 and target annual incentive compensation of $3,120,000, each of which were prorated for 2018. The Compensation Committee (with ratification by the independent members of the Board) will determine the target value of Mr. Roman’s annual long-term incentive grants each year based on market data and his individual performance. Mr. Roman also received special promotion performance share and stock option awards granted at the time of his appointment as Chief Executive Officer that had an aggregate target grant value of $2,500,000, (as described in more detail on page 62). Consistent with the Company’s compensation philosophy, Mr. Roman does not have an employment agreement, severance agreement or change in control agreement.
●	Approved new compensation terms for Inge G. Thulin in connection with his appointment as Executive Chairman, including an annual base salary of $1,000,000 and target annual incentive compensation of $1,500,000 (each prorated for 2018), which represent decreases of approximately 35 percent and 39 percent, respectively. The Compensation Committee (with ratification by the independent members of the Board) will determine the target value of Mr. Thulin’s annual long-term incentive grants each year based on market data and his individual performance. In anticipation of his transition to Executive Chairman in 2018, the aggregate target compensation value for Mr. Thulin’s 2018 long-term incentive compensation awards was reduced by $3,000,000 from the target compensation value established for such awards granted to him in 2017. Mr. Thulin also received a performance share award granted at the time of his appointment as Executive Chairman that had a target grant value of $750,000 (as described in more detailed on page 62). Mr. Thulin’s new compensation terms were approved by the Committee (with ratification by the independent members of the Board) consistent with the recommendation of its independent compensation consultant based on peer and other market data.
●	Expanded the scope of our clawback policy to address situations involving significant financial or reputational harm. For additional information concerning our updated policy, please refer to the section entitled “Clawback Policy” on page 66 of this Proxy Statement.

PROPOSAL

Elect the Twelve Directors Identified in this Proxy Statement ●Elect the twelve directors identified in this Proxy Statement, each for a term of one year. ●Our nominees are distinguished leaders who bring a mix of skills and qualifications to the Board and can represent the interests of all stockholders.

At the 2019 Annual Meeting, twelve directors are to be elected to hold office until the 2020 Annual Meeting of Stockholders and until their successors have been elected and qualified. All nominees are presently 3M directors who were elected by stockholders at the 2018 Annual Meeting, except for Dr. Dambisa Moyo, who joined the Board on August 12, 2018, and Pamela J. Craig, a new nominee, who are standing for election for the first time. The Nominating and Governance Committee, with the assistance of an outside search firm, and input from the independent directors and the Chairman of the Board and Chief Executive Officer, identified Ms. Craig and recommended her to the Board. We expect each nominee for election as a director to be able to serve if elected. If any nominee is not able to serve, proxies will be voted in favor of the remainder of those nominated and may be voted for substitute nominees, unless the Board chooses to reduce the number of directors serving on the Board. Each nominee elected as a director will continue in office until his or her successor has been elected and qualified, or until his or her earlier death, resignation, or retirement. Sondra L. Barbour is not seeking re-election and will end her service on the 3M Board on May 14, 2019, when her term expires. Inge G. Thulin, Executive Chairman of the Board of Directors, announced his intention not to stand for re-election and to retire from the Company on June 1, 2019. Mr. Thulin will remain as Executive Chairman of the Board through the Annual Stockholder Meeting on May 14, 2019. We thank both Ms. Barbour and Mr. Thulin for their many contributions to the Board and to the Company.

The Nominating and Governance Committee reviewed the Board Membership Criteria (described on page 20) and the specific experience, qualifications, attributes, and skills of each nominee, including membership(s) on the boards of directors of other public companies. The following pages contain biographical and other information about the nominees. Following each nominee’s biographical information, we have provided information concerning the particular experience, qualifications, attributes, and skills that are deemed most critical to 3M’s long-term success and led the Nominating and Governance Committee and the Board to determine that each nominee should serve as a director. In addition, the majority of our directors serve or have served on boards and board committees (including as committee chairs) of other public companies, which the Board believes provides them with additional board leadership and governance experience, exposure to best practices, and substantial knowledge and skills that further enhance the functioning of our Board.

Corporate governance at 3M Board membership criteria

Board membership criteria

3M’s Corporate Governance Guidelines contain Board Membership Criteria which include a list of key skills and characteristics deemed critical to serve 3M’s long-term business strategy and expected to be represented on 3M’s Board. The Nominating and Governance Committee periodically reviews with the Board the appropriate skills and characteristics required of Board members given the current Board composition. It is the intent of the Board that the Board, itself, will be a high performance organization creating competitive advantage for the Company. To perform as such, the Board will be composed of individuals who have distinguished records of leadership and success in their arena of activity and who will make substantial contributions to Board operations and effectively represent the interests of all stockholders. The Committee’s and the Board’s assessment of Board candidates includes, but is not limited to, consideration of:

●	Roles in and contributions valuable to the business community;
●	Personal qualities of leadership, character, judgment, and whether the candidate possesses and maintains throughout service on the Board a reputation in the community at large of integrity, trust, respect, competence, and adherence to the highest ethical standards;
●	Relevant knowledge and diversity of background and experience in business, manufacturing, technology, finance and accounting, marketing, international business, government, and other areas; and
●	Whether the candidate is free of conflicts and has the time required for preparation, participation, and attendance at all meetings.

In addition to these minimum requirements, the Committee will also evaluate whether the nominee’s skills are complementary to the existing Board members’ skills, the Board’s needs for particular expertise in certain areas, and will assess the nominee’s impact on Board dynamics, effectiveness, and diversity of experience and perspectives.

Director Nominees – Diversity of Skills and Experience

The diagram below summarizes the director nominees’ key skills and experiences in the areas that are most relevant to 3M and shows the number of director nominees who possess each of the skills and experiences:

Corporate governance at 3M Board membership criteria

Diversity

For 3M, diversity, in its myriad manifestations, is fundamental to innovation, performance, and relevancy. 3M employees reflect that diversity. The Board of Directors regards diversity as an important factor in selecting board nominees to serve on the board. Although the Board has no specific diversity policy, when selecting nominees, it actively considers diversity in recruitment and nomination of directors, such as gender, race, and national origin. The current composition of our Board reflects those efforts and the importance of diversity to the Board.

Identification, Evaluation, and Selection of Nominees

The Committee periodically reviews the appropriate size and composition of the Board and anticipates future vacancies and needs of the Board. In the event the Committee recommends an increase in the size of the Board or a vacancy occurs, the Committee considers qualified nominees from several sources, including current Board members and nominees recommended by stockholders and other persons.

The Committee may from time to time retain a director search firm to help the Committee identify qualified director nominees for consideration by the Committee.

The Committee retained Spencer Stuart in 2018 to help identify future Board candidates.

The Committee evaluates qualified director nominees at regular or special Committee meetings against the Board Membership Criteria described above then in effect and reviews qualified director nominees with the Board. The Committee and the Chairman of the Board interview candidates that meet the Board Membership Criteria and the Committee selects nominees that best suit the Board’s current needs and recommends one or more of such individuals for election to the Board.

Director Independence

The Board has adopted a formal set of Director Independence Guidelines with respect to the determination of director independence, which either conform to or are more exacting than the independence requirements of the New York Stock Exchange (“NYSE”) listing standards, and the full text of which is available on our website at www.3M.com, under Investor Relations — Governance. In accordance with these Guidelines, a director or nominee for director must be determined to have no material relationship with the Company other than as a director. The Guidelines specify the criteria by which the independence of our directors will be determined, including strict guidelines for directors and their immediate family members with respect to past employment or affiliation with the Company or its independent registered public accounting firm. The Guidelines also prohibit Audit and Compensation Committee members from having any direct or indirect financial relationship with the Company, and restrict both commercial and not-for-profit relationships of all directors with the Company. Directors may not be given personal loans or extensions of credit by the Company, and all directors are required to deal at arm’s length with the Company and its subsidiaries, and to disclose any circumstance that might be perceived as a conflict of interest.

In accordance with these Guidelines, the Board undertook its annual review of director independence. During this review, the Board considered transactions and relationships between each director, or any member of his or her immediate family and the Company and its subsidiaries and affiliates in each of the most recent three completed fiscal years. The Board also considered whether there were any transactions or relationships between the Company and a director or any members of a director’s immediate family (or any entity of which a director or an immediate family member is an executive officer, general partner, or significant equity holder). The Board considered that in the ordinary course of business, transactions may occur between the Company and its subsidiaries and companies at which some of our directors are or have been officers. In particular, the Board considered the annual amount of sales to 3M for each of the most recent three completed fiscal years by each of the companies where directors serve or have served as an executive officer, as well as purchases by those companies from 3M. The Board determined that the amount of sales and purchases in each fiscal year was below one percent of the annual revenues of each of those companies, the threshold set forth in the Director Independence Guidelines. The Board also considered charitable contributions to not-for-profit organizations with which our directors or immediate family members are affiliated, none of which approached the threshold set forth in our Director Independence Guidelines.

Thulin, Executive Chairman of the Board, and Michael F. Roman, Chief Executive Officer, are considered to not be independent because of their employment by the Company.

Nominees Proposed by Stockholders

The Committee has a policy to consider properly submitted stockholder recommendations for candidates for membership on the Board of Directors. Stockholders proposing individuals for consideration by the Committee must include at least the following information about the proposed nominee: the proposed nominee’s name, age, business or residence address, principal occupation or employment, and whether such person has given written consent to being named in the Proxy Statement as a nominee and to serving as a director if elected. Stockholders should send the required information about the proposed nominee to:

In order for an individual proposed by a stockholder to be considered by the Committee for recommendation as a Board nominee for the 2020 Annual Meeting, the Corporate Secretary must receive the proposal by November 28, 2019. Such proposals must be sent via registered, certified, or express mail (or other means that allows the stockholder to determine when the proposal was received by the Company). The Corporate Secretary will send properly submitted stockholder proposed nominations to the Committee Chair for consideration at a future Committee meeting. Individuals proposed by stockholders in accordance with these procedures will receive the same consideration received by individuals identified to the Committee through other means.

Stockholder Nominations - Advance Notice Bylaw

In addition, 3M’s Bylaws permit stockholders to nominate directors at an annual meeting of stockholders or at a special meeting at which directors are to be elected in accordance with the notice of meeting. Stockholders intending to nominate a person for election as a director must comply with the requirements set forth in the Company’s Bylaws. With respect to nominations to be acted upon at our 2020 Annual Meeting, our Bylaws would require, among other things, that the Corporate Secretary receive written notice from the record stockholder no earlier than November 28, 2019, and no later than December 28, 2019. The notice must contain the information required by the Bylaws, a copy of which is available on our website at www.3M.com, under Investor Relations — Governance. Nominations received after December 28, 2019, will not be acted upon at the 2020 Annual Meeting.

Proxy Access Nominations

Further, pursuant to the proxy access Bylaw adopted by the Board in November 2015, a stockholder, or a group of up to 20 stockholders, continuously owning for three years at least three percent of our outstanding common shares may nominate and include in our proxy materials up to the greater of two directors and 20 percent of the number of directors currently serving, if the stockholder(s) and nominee(s) satisfy the Bylaw requirements. For eligible stockholders to include in our proxy materials nominees for the 2020 Annual Meeting, proxy access nomination notices must be received by the Company no earlier than November 28, 2019, and no later than December 28, 2019.

Stockholder Rights

The Board has taken numerous actions – including those proposed by stockholders – to promote effective corporate governance and accountability to stockholders.

The meetings included an overview of the Company and a discussion of the Company’s practices on corporate governance, including board refreshment and diversity, director evaluation, directors’ skills matrix, sustainability, succession planning, and board leadership structure. In general, investors viewed the Company’s governance practices favorably, including the Board’s leadership structure, the mix of tenure and overall diversity, and the disclosure regarding the Directors’ skill sets and qualifications.

Risk Oversight

The Board oversees the Company’s risk profile and management’s processes for assessing and managing risk, both as a whole Board and through its committees.

●At least annually, the Board reviews enterprise risks facing the Company and certain of its businesses. Other important categories of risk are assigned to designated Board committees (which are comprised solely of independent directors) that report back to the full Board. The Board has delegated to the Audit Committee through its charter the primary responsibility for the oversight of risks facing the Company including cybersecurity. The Audit Committee’s charter provides that the Audit Committee shall “discuss policies and procedures with respect to risk assessment and risk management, the Company’s major risk exposures and the steps management has taken to monitor and mitigate such exposures.”

Board Approved Long-Term Strategic Plans and Capital Allocation Strategies

Each year management presents to the Board, and the Board discusses and approves, detailed long-term strategic plans for the Company.

●Each year management presents to the Board, and the Board discusses and approves, detailed long-term strategic plans for the Company.

Over the past five years, 3M has returned approximately $21.6 billion to stockholders via share repurchases.

Corporate Governance Guidelines

The Board has adopted Corporate Governance Guidelines which provide a framework for the effective governance of the Company. The guidelines address matters such as the respective roles and responsibilities of the Board and management, the Board’s leadership structure, the responsibilities of the independent Lead Director, director independence, the Board Membership Criteria, Board committees, and Board and management evaluation. The Board’s Nominating and Governance Committee is responsible for overseeing and reviewing the Guidelines at least annually and recommending any proposed changes to the Board for approval. The Corporate Governance Guidelines, the Certificate of Incorporation and Bylaws, the charters of the Board committees, the Director Independence Guidelines, and the Codes of Conduct provide the framework for the governance of the Company and are available on our website at www.3M.com, under Investor Relations — Governance.

Board’s Role in the Company’s Long-Term Strategy

Each year management presents to the Board, and the Board discusses and approves, detailed long-term strategic plans for the Company. In addition to the overall strategic plan for the Company and the business groups, the discussions also focused on breakout sessions with the directors on strategic corporate-wide themes of portfolio management, innovation, commercial transformation, manufacturing and supply chain transformation, and people and culture.

Our Company’s long-term strategy is outlined in the 3M Value Model.

3M VALUE MODEL

The 3M Value Model is what differentiates our company in the marketplace. It’s how we create extraordinary value for customers, and premium returns for shareholders. The model is built around four elements: our vision, our strengths, our priorities, and our values.

Corporate governance at 3M Corporate governance overview

Our Vision

Our vision drives everything we do: 3M Technology Advancing Every Company, 3M Products Enhancing Every Home, 3M Innovation Improving Every Life. It is aspirational and authentic to 3M, and is an important part of the purpose that drives us as an enterprise.

Our Strengths

Our strengths help us continually innovate to create differentiated value for customers at above-market growth rates. They also enable us to take advantages of the changes in customers, technology and commercial channels.

In our Customer Inspired Innovation approach, we combine close engagement with customers, deep domain expertise in markets and the science behind our technology platforms to develop unique insights into the critical needs of our customers.

We then leverage our fundamental strengths. In technology, we leverage our deep intellectual property and broad range of technology platforms. In manufacturing, we leverage our unique capabilities in process engineering. Our global capabilities enable us to take that technology and manufacturing strength and deliver through our go-to-market models to serve customers around the world. And finally, our brand adds value in each of our businesses.

We do this while maintaining a focus on our customers – the end users of our solutions. Most of our sales are specified or designed into customer applications. While the channel to our end user may change over time, our global commerce strategy is to connect directly with end users while leveraging the go-to-market model that will deliver where, when and how the end user wants.

Our Priorities

We have four priorities that are positioning us for long-term growth and value creation: Portfolio, Transformation, Innovation, and People & Culture. The first three are levers that have been proven to create extraordinary value over time. They form the foundation of our priorities moving forward. They depend on our efforts to advance people and culture. Our focus on advancing people and culture supports the entire value model.

Our Values

Our values bind us together as one 3M – across business groups and geographies. They include our leadership behaviors – how we want our leaders to act to drive performance, develop others, and continue to win in the marketplace. Then our Code of Conduct; great companies are built on trust from customers, shareholders, employees, communities. We’ve earned that trust and our reputation for integrity over many decades. No one at 3M is free to compromise it. We also have four values that will be a priority moving forward. We are working to make 3M the most inclusive enterprise we can be. This will help us become even more diverse and enable us to become an even more creative and innovative company. We have long been a leader in sustainability and we will continue to advance this across the company. Finally, we will do even more to encourage and challenge every 3M employee to be their best.

Board’s Role in Risk Oversight

The Board oversees the Company’s risk profile and management’s processes for assessing and managing risk, both as a whole Board and through its committees. At least annually, the Board reviews enterprise risks facing the Company and certain of its businesses. Other important categories of risk are assigned to designated Board committees (which are comprised solely of independent directors) that report back to the full Board. The Board has delegated to the Audit Committee through its charter the primary responsibility for the oversight of risks facing the Company including cybersecurity. The Audit Committee’s charter provides that the Audit Committee shall “discuss policies and procedures with respect to risk assessment and risk management, the Company’s major risk exposures and the steps management has taken to monitor and mitigate such exposures.”

Corporate governance at 3M Corporate governance overview

The Vice President and General Auditor, Corporate Auditing (the “Auditor”), whose appointment and performance is reviewed and evaluated by the Audit Committee and who has direct reporting obligations to the Committee, is responsible for leading the formal risk assessment and management process within the Company. The Auditor, through consultation with the Company’s senior management, periodically assesses the major risks facing the Company and works with those executives responsible for managing each specific risk. The Auditor periodically reviews with the Audit Committee the major risks facing the Company and the steps management has taken to monitor and mitigate those risks. The Auditor’s risk management report, which is provided in advance of the meeting, is reviewed with the entire Board by either the chair of the Audit Committee or the Auditor. The executive responsible for managing a particular risk may also report to the full Board on how the risk is being managed and mitigated.

The Board has delegated to other committees the oversight of risks within their areas of responsibility and expertise. For example, the Compensation Committee oversees risks associated with the Company’s compensation practices, including by performing an annual review of the Company’s risk assessment of its compensation policies and practices for its employees. The Finance Committee oversees risks associated with the Company’s capital structure, credit ratings and cost of capital, long-term benefit obligations, and use of or investment in financial products, such as derivatives to manage risk related to foreign currencies, commodities, and interest rates. The Nominating and Governance Committee oversees risks associated with the Company’s overall governance and its succession planning process to ensure that the Company has a slate of future, qualified candidates for key management positions.

The Board believes that its oversight of risks, primarily through delegation to the Audit Committee, but also through delegation to other committees to oversee specific risks within their areas of responsibility and expertise, and the sharing of information with the full Board, is appropriate for a diversified technology and manufacturing company like 3M. The chair of each committee that oversees risk provides a summary of the matters discussed with the committee to the full Board following each committee meeting. The minutes of each committee meeting are also provided to all Board members. The Board also believes its oversight of risk is enhanced by its current leadership structure (further discussed below) because the Executive Chairman, who served as our CEO and was ultimately responsible for the Company’s management of risk, also chairs regular Board meetings. Given his in-depth knowledge and understanding of the Company, the Executive Chairman is best able to bring key business issues and risks to the Board’s attention.

Management Succession Planning

The Board plans the succession to the position of Chairman, CEO and other senior management positions. To assist the Board, the Chairman, CEO and Senior Vice President of Human Resources annually assess senior managers and their succession potential for the position of Chairman/CEO and other senior management positions. As a result of a thorough and thoughtful succession planning process, on March 5, 2018, the Board appointed Michael F. Roman CEO, effective July 1, 2018, succeeding Inge G. Thulin.

Communication with Directors

The Board of Directors has adopted the following process for stockholders and other interested parties to send communications to members of the Board. Stockholders and other interested parties may communicate with the Lead Director, the chairs of the Audit, Compensation, Finance, and Nominating and Governance Committees of the Board, or with any of our other independent directors, or all of them as a group, by sending a letter to the following address: Corporate Secretary, 3M Company, 3M Center, Building 220-13E-26A, St. Paul, MN 55144-1000. The Corporate Secretary reviews communications to the independent directors and forwards those communications to the independent directors as discussed below. Communications involving substantive accounting or auditing matters will be immediately forwarded to the Chair of the Audit Committee and the Company’s Chief Compliance Officer consistent with time frames established by the Audit Committee for the receipt of communications dealing with these matters. Communications that pertain to non-financial matters will be forwarded promptly. Items that are unrelated to the duties and responsibilities of the Board will not be forwarded, such as: business solicitation or advertisements; product-related inquiries; junk mail or mass mailings; resumes or other job-related inquiries; and spam.

3M’s Codes of Conduct

More than a century of operating with uncompromising integrity has earned 3M trust from our customers, credibility with our communities, and dedication from our employees. All of our employees, including our Chief Executive Officer, Chief Financial Officer, and Chief Accounting Officer, are required to abide by 3M’s Code of Conduct to ensure that our business is conducted in a consistently legal and ethical manner. These policies form the foundation of a comprehensive process that includes compliance with corporate policies and procedures and a Company-wide focus on uncompromising integrity in every aspect of our operations. Our Code of Conduct covers many topics, including antitrust and competition law, conflicts of interest, financial reporting, protection of confidential information, and compliance with all laws and regulations applicable to the conduct of our business.

Employees are required to report any conduct that they believe in good faith to be an actual or apparent violation of the Code of Conduct. The Audit Committee has adopted procedures to receive, retain, and treat complaints received regarding accounting, internal accounting controls, or auditing matters, and to allow for the confidential and anonymous submission by employees or others of concerns regarding questionable accounting or auditing matters. Information on how to submit any such communications can be found on 3M’s Investor Relations website, under Governance — Governance Documents — Employee Business Conduct Policies — “Report a concern or ask a question.” Our Chief Compliance Officer, who has direct reporting obligations to the Audit Committee, periodically reports to the Audit Committee on compliance with the Company’s Code of Conduct, including the effectiveness of the Company’s compliance program.

The Board also has adopted a Code of Business Conduct and Ethics for Directors of the Company. This Code incorporates long-standing principles of conduct the Company and the Board follow to ensure the Company’s business and the activities of the Board are conducted with integrity and adherence to the highest ethical standards, and in compliance with the law. The Company’s Code of Conduct for employees and the Code of Business Conduct and Ethics for Directors are available on our website at www.3M.com under Investor Relations — Governance — Governance Documents.

Public Policy Engagement

The Company believes that transparency with respect to the consideration, processes, and oversight of our engagement with lawmakers is important to our stockholders, and continuously makes efforts to give our stockholders useful information about our public policy engagement. Since 2007, the Company has voluntarily published a detailed explanation of the Company’s political activities which is available on our website at www.3M.com under Investor Relations — Governance — Governance Documents — “Political Activities and Issue Advocacy.” There, the Company sets out in detail its positions on important public policy issues, the factors we consider when making political contributions, and the processes we use for legal, financial, executive, and Board oversight of our political activities and contributions. We also provide links to the reports the 3M Political Action Committee files monthly with the Federal Election Commission and the Company’s quarterly Lobbying Disclosure reports, as well as a detailed list of our contributions to state candidates and political parties, and contributions to “527” political organizations. The Company also discloses on its website the trade associations the Company joined where $25,000 or more of the dues are allocated for lobbying purposes by the trade association. The Company believes that these disclosures on our website, which exceed the disclosures required by law, offer transparency respecting the Company’s public policy engagement and political activities.

Commitment to the Environment and Sustainability

At 3M, we are working hard to advance every company, enhance every home, and improve every life. We apply our expertise, and technology to solve problems collaboratively, and with a focus on long term, sustainable solutions that demonstrate our commitment and societal purpose. Sustainability is fundamental to our business — from sustainability-inspired innovation to product stewardship to sustainability in our operations. As we seek to improve every life, we see partnerships to help our customers and communities achieve their sustainability goals as key to that ambition.

Corporate governance at 3M Compliance

For more than 40 years, 3M has been a leader among global corporations in sustainability actions and measures, beginning with the creation of its groundbreaking Pollution Prevention Pays (3P) Program in 1975. As a global corporation, we believe that we have a significant responsibility to society globally, and responsibility to the local communities in which we live and work. Our corporate vision states: “3M technology advancing every company... 3M products enhancing every home... and 3M innovation improving every life.” It is that vision — carried out in collaboration with our customers, communities, and partners — that guides our sustainability strategies and goals and aspirations. Our sustainability efforts improve 3M operations and the operations of our customers. Our product solutions help customers manage their environmental footprint - from paint systems that reduce the need for cleaning solvents to window films that ease energy consumption. Our life cycle management process enables teams to select more sustainable components and encourage more sustainable processes. In addition, our philanthropic and social sustainability programs support the workforce of the future – both in Science, Technology, Engineering and Math (STEM), as well as the skilled trades. For example, our skills-based volunteering programs for employees encourage sustainability thinking inside the company while supporting the environmental and social needs in our local communities. Our 2025 sustainability goals provide us with a holistic approach to driving sustainability in our own operations, in our communities, and for the needs of our customers.

In January 2013, our CEO elevated the company’s focus on sustainability, with emphasis in two areas: (1) developing and commercializing products which help our customers solve their sustainability challenges; and, (2) driving sustainability within 3M operations and supply chain. Sustainability is now embedded across the company with dedicated teams in R&D, Supply Chain, business groups, and regions across the globe. Our Science, Technology, and Sustainability Executive Committee provides leadership, oversight, and strategy to encourage and ensure sustainability opportunities are recognized and strong policies and procedures are in place. Our Chief Technology Officer and our Chief Sustainability Officer report annually to the Board’s Nominating and Governance Committee on our sustainability efforts. In addition, our Corporate EHS and Business Conduct Committee ensures our sustainability principles are embedded throughout the company. In December 2018, 3M announced that starting in 2019 every new product will be required to have a Sustainability Value Commitment that builds on 3M’s history of creating products that emphasize reuse, recycling, and reduced resource use for 3M’s operations and for our customers. As of March 1, 2019, 3M's global headquarters in St. Paul – which is home to our largest employee base – will be powered by 100% renewable energy. We are also committing to move our entire global operations to 100% renewable energy, with an interim target of 50% by 2025. As part of this initiative 3M will be joining RE100, an influential group of companies committed to 100% renewable energy.

As part of our sustainability efforts, we are a signatory to the United Nations Global Compact on Human Rights — a policy initiative for businesses to demonstrate their commitment to ten principles in the areas of human rights, labor, environment, and anti-corruption. We also align our goals and programs to the United Nations Sustainable Development Goals. We report annually on these efforts in our Sustainability Report.

Related Person Transaction Policy and Procedures

The Board of Directors has adopted a written Related Person Transaction Policy and Procedures which is administered by the Nominating and Governance Committee. This Policy applies to any transaction or series of transactions in which the Company or a subsidiary is a participant, the amount involved exceeds $120,000, and a Related Person (as that term is defined in the Policy) has a direct or indirect material interest and which is required to be disclosed under Item 404(a) of Regulation S-K. Transactions that fall within this definition are referred to the Committee for approval, ratification, or other action. Based on its consideration of all of the relevant facts and circumstances, the Committee decides whether or not to approve a transaction and approves only those transactions that are in the best interests of the Company. In the course of its review and approval or ratification of a transaction, the Committee considers:

●	The nature of the Related Person’s interest in the transaction;
●	The material terms of the transaction, including whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar circumstances;
●	The significance of the transaction to the Related Person;
●	The significance of the transaction to the Company;
●	Whether the transaction would impair the judgment of a director or executive officer to act in the best interest of the Company; and
●	Any other matters the Committee deems appropriate.

Corporate governance at 3M Board structure and processes

Any Committee member who is a Related Person with respect to a transaction under review may not participate in the deliberations or vote respecting such approval or ratification, except that such a director may be counted in determining the presence of a quorum at a meeting at which the Committee considers the transaction. There were no Related Person Transactions that were referred to the Committee in 2018.

Policy on Adoption of a Rights Plan

In 2002 and 2003, a 3M stockholder submitted a stockholder proposal to 3M regarding the approval process for adopting a stockholders’ rights plan (also known as a “poison pill”). 3M does not have a rights plan and is not currently considering adopting one. The Board continues to believe, however, that there may be circumstances under which adoption of a rights plan would give the Board the negotiating power and leverage necessary to obtain the best result for 3M stockholders in the context of a takeover effort.

Following consideration of the favorable vote the stockholder proposal received and in light of this belief, the Board adopted and has reaffirmed a statement of policy on this topic. The Board’s policy is that it will only adopt a rights plan if either: (1) stockholders have approved adoption of the rights plan; or (2) the Board (including a majority of the independent members of the Board), in its exercise of its fiduciary responsibilities, makes a determination that, under the circumstances existing at the time, it is in the best interests of 3M’s stockholders to adopt a rights plan without the delay in adoption resulting from seeking stockholder approval.

The Board has directed the Nominating and Governance Committee to review this policy statement on an annual basis and to report to the Board on any recommendations it may have concerning the policy. The terms of the policy, as in effect, are included in 3M’s published Corporate Governance Guidelines and its Proxy Statement.

Board structure and processes

Board’s Leadership Structure

On March 5, 2018, the Board announced that Michael F. Roman would succeed Inge G. Thulin as Chief Executive Officer effective July 1, 2018. To help ensure a smooth transition, the Board asked Mr. Thulin to continue to serve as Executive Chairman of the Board, also effective on July 1, 2018. According to the Board’s Corporate Governance Guidelines, the Board has the authority to decide whether the positions of Chairman and CEO should be held by the same person and determine the best arrangement for the Company and its shareholders considering all relevant and changing circumstances. On February 6, 2019, the Board announced that CEO Michael Roman will be nominated to serve as Chairman of the Board following the Company’s Annual Meeting of Stockholders on May 14, 2019. Inge Thulin, 3M’s current Executive Chairman, announced his intention not to stand for re-election and to retire from the Company on June 1, 2019.

Following the Company’s Annual Meeting of Stockholders, the Board’s leadership structure will consist of:

●	A combined Chairman of the Board and CEO;
●	A strong, independent, and highly experienced Lead Director with well-defined responsibilities that support the Board’s oversight responsibilities;
●	A robust committee structure consisting entirely of independent directors with oversight of various types of risks; and
●	An engaged and independent Board.

The Board of Directors believes that this leadership structure provides independent board leadership and engagement while deriving the benefits of having our CEO also serve as Chairman of the Board. As the individual with primary responsibility for managing the Company’s day-to-day operations and with in-depth knowledge and understanding of the Company, the CEO is best positioned to chair regular Board meetings as the directors discuss key business and strategic issues. Coupled with an independent Lead Director, this combined structure provides independent oversight while avoiding unnecessary confusion regarding the Board’s oversight responsibilities and the day-to-day management of business operations.

The Board believes that adopting a rigid policy on whether to separate or combine the positions of Chairman of the Board and CEO would inhibit the Board’s ability to provide for a leadership structure that would best serve stockholders. As a result, the Board has rejected adopting a policy permanently separating or combining the positions of Chairman and CEO in its Corporate Governance Guidelines, which are reviewed at least annually and available on our website at www.3M.com, under Investor Relations — Governance. Instead, the Board adopted an approach that allows it, in representing the stockholders’ best interests, to decide who should serve as Chairman or CEO, or both, under present or anticipated future circumstances.

Corporate governance at 3M Board structure and processes

The Board believes that combining the roles of CEO and Chairman contributes to an efficient and effective Board. The Board believes that to drive change and continuous improvement within the Company, tempered by respect for 3M’s traditions and values, the CEO must have maximum authority. The CEO is primarily responsible for effectively leading significant change, improving operational efficiency, driving growth, managing the Company’s day-to-day business, managing the various risks facing the Company, and reinforcing the expectation for all employees of continuing to build on 3M’s century-old tradition of uncompromising integrity and doing business the right way.

The Board believes that the Company’s corporate governance measures ensure that strong, independent directors continue to effectively oversee the Company’s management and key issues related to executive compensation, CEO evaluation and succession planning, strategy, risk, and integrity. The Corporate Governance Guidelines provide, in part, that:

●	Independent directors comprise a substantial majority of the Board;
●	Directors are elected annually by a majority vote in uncontested director elections;
●	Only independent directors serve on the Audit, Compensation, Finance, and Nominating and Governance Committees;
●	The committee chairs establish their respective agendas;
●	The Board and committees may retain their own advisors;
●	The independent directors have complete access to management and employees;
●	The independent directors meet in executive session without the CEO or other employees during each regular Board meeting; and
●	The Board and each committee regularly conduct a self-evaluation to determine whether it and its committees function effectively.

The Board has also designated one of its members to serve as Lead Director, with responsibilities (described in the next section) that are similar to those typically performed by an independent chairman.

Independent Lead Director

The Board has designated one of its members to serve as a Lead Director, with responsibilities that are similar to those typically performed by an independent chairman (“Lead Director”). Michael L. Eskew was appointed Lead Director by the independent directors effective November 12, 2012, succeeding Dr. Vance Coffman who had served as Lead Director since 2006. Michael Eskew is a highly experienced director, currently serving on the boards of The Allstate Corporation, Eli Lilly and Company, and International Business Machines Corporation, and is the former Chairman and CEO of United Parcel Service, Inc. His responsibilities include, but are not limited to, the following:

●	Presides at all meetings of the Board at which the Chairman is not present, including executive sessions of the independent directors;
●	Acts as a key liaison between the Chairman/CEO and the independent directors;
●	Approves the meeting agendas for the Board, and approves the meeting schedules to assure that there is sufficient time for discussion of all agenda items;
●	Has the authority to approve the materials to be delivered to the directors in advance of each Board meeting and provides feedback regarding the quality, quantity, and timeliness of those materials (this duty not only gives the Lead Director approval authority with respect to materials to be delivered to the directors in advance of each Board meeting but also provides a feedback mechanism so that the materials may be improved for future meetings);
●	Has the authority to call meetings of the independent directors;
●	Communicates Board member feedback to the Chairman/CEO (except that the chair of the Compensation Committee leads the discussion of the Chairman/CEO’s performance and communicates the Board’s evaluation of that performance to the Chairman/CEO);
●	If requested by major stockholders, ensures that he is available, when appropriate, for consultation and direct communication; and
●	Performs such other duties as requested by the independent directors.

Executive Sessions

As an agenda item for every regularly scheduled Board and committee meeting, independent directors regularly meet in executive session, without the Chairman/CEO or other members of management present, to consider such matters as they deem appropriate. The Lead Director presides over the Board’s executive sessions.

Board, Committees, and Director Evaluations

The Board conducts an annual self-evaluation to determine whether it and its committees are functioning effectively and consider opportunities for continual enhancement. The Nominating and Governance Committee solicits and receives comments from all directors and shares those comments with the Board. Based on the comments and further discussion and reflection, the Board makes an assessment reviewing areas in which the Board believes improvements could be made to increase the effectiveness of the Board and its committees as well as identifying existing practices which have contributed to high effectiveness and accordingly should be continued. Self-evaluation items requiring follow-up and/or the development and execution of implementation and action plans are monitored on a going-forward basis by the full Board, as well as by individual committees and the chairs thereof, as applicable. While this formal self-evaluation is conducted on an annual basis, directors share perspectives, feedback, and suggestions year-round. The Board and each committee conducted an evaluation of its performance in 2018.

Before the November Board meeting, the Chairman/CEO, Lead Director, and chair of the Nominating and Governance Committee meet to discuss the performance and contributions of each director. As part of the nomination process, the Nominating and Governance Committee considers the performance and contributions of each director and evaluates each of the directors to ensure our directors continue to possess the necessary skills and experience to effectively oversee the Company. On occasion, the Nominating and Governance Committee has not renominated a director based on this individual director evaluation process.

Board and Committee Information

The Board currently has thirteen directors and the following four committees: Audit, Compensation, Finance, and Nominating and Governance. The membership and the function of each committee are described below.

During 2018, the Board of Directors held five regularly scheduled meetings and three telephonic meetings. Overall attendance at Board and committee meetings was 97 percent. During 2018, all of our directors attended at least 75 percent of all Board and Committee meetings on which they served.

The Company has a long-standing policy that directors are expected to attend the Annual Meeting of Stockholders unless extenuating circumstances prevent them from attending. All directors who were members of the Board as of May 2018 attended last year's Annual Meeting of Stockholders, except one director was unable to attend due to illness. Dr. Vance Coffman was also not present at the meeting as he was no longer eligible to stand for re-election to the Board, having reached the mandatory retirement age under the Board's Corporate Governance Guidelines.

Director compensation and stock ownership guidelines

Director Compensation Philosophy and Elements

The Nominating and Governance Committee periodically receives reports on the status of Board compensation in relation to other large U.S. companies and is responsible for recommending to the Board changes in compensation for non-employee directors. In developing its recommendations, the Committee is guided by the following goals:

●	Compensation should fairly pay directors for work required in a company of 3M’s size and scope;
●	A significant portion of the total compensation should be paid in common stock to align directors’ interests with the long-term interests of stockholders; and
●	The structure of the compensation should be simple and transparent.

The Nominating and Governance Committee works with an independent compensation consultant to support its objectives of maintaining a reasonable and appropriate program. For 2018, Frederic W. Cook & Co., Inc. (“FW Cook”) provided the Committee with expert advice on the compensation of non-employee directors, in addition to analyzing market data on director compensation at the same peer group of 17 companies approved by the Compensation Committee for evaluating Named Executive Officer compensation. Neither the Company nor the Nominating and Governance Committee has any arrangement with any other compensation consultant who has a role in determining or recommending the amount or form of director compensation.

Our director program is comprised of a mix of cash and equity that is intended to approximate the peer-group median mix. Our directors’ overall target total direct compensation is consistent with 3M’s size and market-capitalization value relative to its peers. In addition, our hold-until-termination requirement on the annual stock retainer is rigorous relative to the holding requirement of our peers. For more information on the peer group, please see the section entitled “Executive Peer Group” beginning on page 56 of this Proxy Statement. Non-employee directors’ compensation includes the following compensation elements:

Annual Compensation — In May 2018, the Nominating and Governance Committee considered a board compensation study prepared by FW Cook. After reviewing that study, the Committee recommended and the Board approved an increase of $10,000 in the annual compensation for non-employee directors from $295,000 to $305,000, effective January 1, 2018. The annual cash retainer was increased $5,000 (from $130,000 to $135,000). The annual stock retainer was also increased $5,000 (from $165,000 to $170,000). Approximately 44 percent of the annual compensation (or $135,000) is payable in cash in four quarterly installments and approximately 56 percent of the annual compensation (or $170,000) is payable in common stock after the Annual Meeting. In addition, the chair of the Audit Committee receives an additional annual fee of $25,000 and the chairs of the Compensation, Finance and Nominating and Governance Committees each receive an additional annual fee of $20,000. The additional annual fee for the Lead Director also was increased from $30,000 to $35,000, effective January 1, 2018. There are no meeting fees. In lieu of the cash fees, a director may elect to receive common stock of the Company. Non-employee directors may also voluntarily defer all or part of their annual cash fees or stock awards until they cease to be members of the Board.

Deferred Stock — For directors who elect to receive all or a portion of their annual stock retainer or annual cash retainer in deferred stock, the Company credits their accounts with a number of 3M common stock equivalents (“Deferred Stock Units”) equal to the number of actual shares (including fractional shares) of 3M common stock that could have been purchased with such deferred amounts on the first day of the calendar quarter, using the closing sales price of 3M common stock on the NYSE for the last business day immediately preceding such date. In addition, on each payment date for dividends on 3M common stock, the Company credits the directors’ accounts with an additional number of Deferred Stock Units having a value equal to the aggregate dividends that otherwise would have been paid on the shares underlying the Deferred Stock Units credited to their accounts on the relevant dividend record date, using the closing sales price of 3M common stock on the NYSE for the sixth business day preceding the dividend record date. The Deferred Stock Units are fully vested upon grant but do not have voting rights. Appropriate adjustments to the number of Deferred Stock Units credited to each director’s account will be made for stock splits, stock dividends, mergers, consolidations, payments of dividends other than in cash, and similar circumstances affecting 3M common stock. The shares of 3M common stock underlying the Deferred Stock Units will be distributed in a single lump sum during the month of January in the first year after the director leaves the Board, unless the non-employee director elects an alternative distribution schedule prior to the beginning of the year in which the fees are earned. Non-employee directors may elect to receive distribution of the shares of 3M common stock underlying his or her Deferred Stock Units for a year in either a lump sum

payment on the first business day of any of the first through tenth years following the year in which the non-employee director leaves the Board or in a number of annual installments (not to exceed ten) beginning on the first business day of the year following the year in which he or she leaves the Board.

The Board amended and restated the 3M Compensation Plan for Nonemployee Directors, effective January 1, 2019, in order to implement certain changes in the day-to-day administration of the plan and improve conformity to certain market practices. Under the terms of the plan, as amended and restated, all deferred amounts and dividends will be converted to Deferred Stock Units using the closing sales price for a share of 3M common stock on the NYSE for the last trading day immediately preceding the date such amounts otherwise would have been paid if not deferred. The number of distribution alternatives available to non-employee directors also was reduced. For plan years beginning on or after January 1, 2019, non-employee directors may now elect to receive distribution of the shares of 3M common stock underlying their Deferred Stock Units only in a single lump sum during the month of January in the first or second year following the year in which they leave the Board or in a series of three, five, or ten annual installments beginning on the first business day of January in the first year following their termination of Board service.

All Other Compensation — The column below showing “All Other Compensation” includes the incremental cost of complimentary products and matching gifts. The non-employee directors are eligible to participate in the Company’s matching gift program on the same terms as 3M employees. Under this program, the 3M Foundation will match up to a total of $5,000 a year in contributions by the director to eligible institutions of higher education.

Reasonableness of Non-Employee Director Compensation

As described above, our philosophy on director compensation is to pay directors fairly for work required in a company of our size and complexity, make a significant portion of the total compensation equity based to align directors’ interests with those of our stockholders and structure compensation in a simple and transparent manner. We believe that the application of this philosophy has resulted in a non-employee director compensation program that reflects best-in-class design with the following provisions:

●	Retainer-only cash compensation with no fees for attending meetings that are an expected part of board service.
●	Additional retainers for special roles having greater responsibilities, such as Lead Director and committee chairs, to recognize the incremental additional time and effort required.
●	Equity delivered in the form of full-value shares, where annual grants are based on a competitive fixed-value formula and immediate vesting helps avoid director entrenchment.
●	A requirement to retain the stock retainer portion of annual compensation issued on or after October 1, 2007, until termination from Board service, which includes net after-tax shares attributable to current payments and pre-tax shares attributable to deferrals.
●	Flexible voluntary deferral provisions and no material benefits or perquisites.
●	Our 2016 Long-Term Incentive Plan, approved by shareholders at the 2016 Annual Meeting, includes a $600,000 annual compensation limit on all forms of compensation for non-employee directors.

Stock Ownership Guidelines

The Board requires that each director retain the stock retainer portion (currently valued at $170,000) of the annual compensation issued on or after October 1, 2007, until the director leaves the Board. Information regarding accumulated stock and deferred stock units is set forth in the section entitled “Security Ownership of Management” beginning on page 85 of this Proxy Statement.

Hedging and Pledging Policies

The Company’s stock trading policies prohibit directors and the Company’s executive officers from (i) purchasing any financial instrument that is designed to hedge or offset any decrease in the market value of the Company’s common stock, including prepaid variable forward contracts, equity swaps, collars and exchange funds; (ii) engaging in short sales related to the Company’s common stock; (iii) placing standing orders; (iv) maintaining margin accounts; and (v) pledging 3M securities as collateral for a loan. All transactions in 3M securities by directors and executive officers must be pre-cleared with the Deputy General Counsel.

PROPOSAL

Ratification of the Appointment of Independent Registered Public Accounting Firm for 2019 ●Ratify the appointment of PricewaterhouseCoopers LLP as 3M’s independent registered public accounting firm for 2019. ●Based on its assessment of the qualifications and performance of PricewaterhouseCoopers LLP (“PwC”) the Audit Committee believes that it is in the best interests of the Company and its stockholders to retain PwC.

The Audit Committee is directly responsible for the appointment, compensation (including approval of all fees), retention, and oversight of the Company’s independent registered public accounting firm (“Independent Accounting Firm”) retained to perform the audit of our financial statements and our internal control over financial reporting.

The Audit Committee has appointed PricewaterhouseCoopers LLP (“PwC”) to serve as 3M’s Independent Accounting Firm for 2019. PwC has been 3M’s Independent Accounting Firm since 1998. Prior to that, 3M’s Independent Accounting Firm was Coopers & Lybrand from 1975 until its merger with Price Waterhouse in 1998. In accordance with SEC rules and PwC policy, audit partners are subject to rotation requirements to limit the number of consecutive years an individual partner may provide service to our Company. For lead and concurring audit partners, the maximum number of consecutive years of service in that capacity is five years. The process for selection of the Company’s lead audit partner pursuant to this rotation policy involves a meeting between the Chair of the Audit Committee and the candidate for the role, as well as discussion by the full Committee and with management.

The Audit Committee annually reviews PwC’s independence and performance in connection with the Audit Committee’s determination of whether to retain PwC or engage another firm as our Independent Accounting Firm. In the course of these reviews, the Audit Committee considers, among other things:

●	PwC’s historical and recent performance on the 3M audit, including input from those 3M employees with substantial contact with PwC throughout the year about PwC’s quality of service provided, and the independence, objectivity, and professional skepticism demonstrated throughout the engagement by PwC and its audit team;
●	an analysis of PwC’s known legal risks and significant proceedings;
●	external data relating to audit quality and performance, including recent Public Company Accounting Oversight Board (“PCAOB”) reports on PwC and its peer firms;
●	PwC’s independence;
●	the appropriateness of PwC’s fees, on both an absolute basis and as compared to its peer firms;
●	PwC’s tenure as our independent auditor and its familiarity with our global operations and businesses, accounting policies and practices and internal control over financial reporting; and
●	PwC’s capability and expertise in handling the breadth and complexity of our global operations, including the Company’s phased implementation of an enterprise resource planning system on a worldwide basis over the next several years.

Based on this evaluation, the Audit Committee believes that PwC is independent and that it is in the best interests of the Company and our stockholders to retain PwC to serve as our Independent Accounting Firm for 2019.

We are asking our stockholders to ratify the selection of PwC as our Independent Accounting Firm for 2019. Although ratification is not required by our Bylaws or otherwise, the Board is submitting the selection of PwC to our stockholders for ratification as a matter of good corporate governance. If the selection of PwC is not ratified, the Audit Committee will consider whether it is appropriate to select another Independent Accounting Firm. Even if the selection is ratified, the Audit Committee may in its discretion select a different Independent Accounting Firm at any time during the year if it determines that such a change would be in the best interests of the Company and our stockholders.

RECOMMENDATION OF THE AUDIT COMMITTEE

The Audit Committee of the Board of Directors unanimously recommends a vote  “FOR”  the ratification of the appointment of PricewaterhouseCoopers LLP as the Company’s independent registered public accounting firm for 2019. Proxies solicited by the Board of Directors will be voted  “FOR”  ratification unless a stockholder indicates otherwise in voting the proxy.

Audit Committee Report

The Audit Committee oversees the Company’s financial reporting process on behalf of the Board of Directors. The management of the Company is responsible for (i) the preparation of complete and accurate annual and quarterly consolidated financial statements (“financial statements”) in accordance with generally accepted accounting principles in the United States, (ii) maintaining appropriate accounting and financial reporting principles and policies and internal controls designed to assure compliance with accounting standards and laws and regulations, and (iii) an assessment of the effectiveness of internal control over financial reporting. The Independent Accounting Firm is responsible for planning and conducting in accordance with the standards of the Public Company Accounting Oversight Board (“PCAOB”) an audit of the Company’s annual consolidated financial statements and a review of the Company’s quarterly financial statements and expressing opinions on the Company’s financial statements and internal control over financial reporting based on the integrated audits.

In this context, the Audit Committee has met and held discussions with management and the Independent Accounting Firm regarding the fair and complete presentation of the Company’s results and the assessment of the Company’s internal control over financial reporting. The Audit Committee has discussed significant accounting policies applied by the Company in its financial statements,as well as alternative treatments. Management has represented to the Audit Committee that the Company’s consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States, and the Audit Committee has reviewed and discussed the consolidated audited financial statements with management and the Independent Accounting Firm. The Audit Committee has discussed with the Independent Accounting Firm matters required to be discussed pursuant to the PCAOB’s Auditing Standards on Communications with Audit Committees, as currently in effect.

In addition, the Audit Committee has reviewed and discussed with the Independent Accounting Firm the auditor’s independence from the Company and its management. As part of that review, the Audit Committee has received the written disclosures and the letters required by applicable requirements of the PCAOB regarding the Independent Accounting Firm’s communications with the Audit Committee concerning independence, and the Audit Committee has discussed the Independent Accounting Firm’s independence from the Company.

The Audit Committee also has considered whether the Independent Accounting Firm’s provision of non-audit services to the Company is compatible with the auditor’s independence. The Audit Committee has concluded that the Independent Accounting Firm is independent from the Company and its management.

The Audit Committee has discussed with the Company’s Internal Audit Department and Independent Accounting Firm the overall scope of and plans for their respective audits. The Audit Committee meets with the Internal Auditor, Chief Compliance Officer, the General Counsel, and representatives of the Independent Accounting Firm in regular and executive sessions, to discuss the results of their examinations, the evaluations of the Company’s internal controls, and the overall quality of the Company’s financial reporting and compliance programs.

In reliance on the reviews and discussions referred to above, the Audit Committee has recommended to the Board of Directors, and the Board has approved, that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018, for filing with the SEC.

Audit committee matters Proposal 2

Audit Committee Policy on Pre-Approval of Audit and Permissible Non-Audit Services of the Independent Accounting Firm

The Audit Committee is responsible for appointing and overseeing the work of the Independent Accounting Firm. The Audit Committee has established a policy requiring its pre-approval of all audit and permissible non-audit services provided by the Independent Accounting Firm.

The policy identifies the guiding principles that must be considered by the Audit Committee in approving services to ensure that the Independent Accounting Firm’s independence is not impaired; describes the Audit, Audit-Related, Tax and All Other services that may be provided and the non-audit services that may not be performed; and sets forth the pre-approval requirements for all permitted services. The policy provides for the general pre-approval of specific types of Audit, Audit-Related and Tax services and a limited fee estimate range for such services on an annual basis as set forth in the engagement letter with the Independent Accounting Firm. The policy requires specific pre-approval of all other permitted services. The Independent Accounting Firm is required to report periodically to the Audit Committee regarding the extent of services provided in accordance with their pre-approval and the fees for the services performed to date.

The Audit Committee’s policy delegates to its Chair the authority to address requests for pre-approval of services in certain limited circumstances between Audit Committee meetings. The chair, in his discretion, must either seek immediate approval by e-mail from the other Audit Committee members, or report any pre-approval decisions to the Audit Committee for its approval at its next scheduled meeting.

The Audit Committee may not delegate to management the Audit Committee’s responsibility to pre-approve permitted services of the Independent Accounting Firm.

All Audit, Audit-Related, Tax and All Other services described below were approved by the Audit Committee before services were rendered.

Fees of the Independent Accounting Firm

The following table represents fees billed for professional services rendered by PricewaterhouseCoopers LLP (“PwC”) for the audit of the Company’s consolidated financial statements for the years ended December 31, 2017 and 2018, and fees billed for other services rendered by PwC during those periods.

AUDIT AND NON-AUDIT FEES ($ IN MILLIONS)

Audit Fees:		$	17.4			$18.6
Audit-Related Fees:			1.2			1.3
Tax Fees:			0.9			0.7
All Other Fees:			0.1			0.2
Total		$	19.7			$20.8

In the above table, in accordance with SEC rules, “Audit” fees consisted of audit work and review services, as well as work generally only the independent registered public accounting firm can reasonably be expected to provide, such as statutory audits, comfort letters, consents, and review of documents filed with the Securities and Exchange Commission. “Audit-related” fees consisted principally of procedures related to the adoption of new accounting standards in future years, internal control and system audit procedures for periods prior to the rollout of the ERP system, agreed-upon procedures, employee benefit plan audits, and other attestation services. “Tax” fees consisted principally of tax compliance services in foreign jurisdictions, assistance with transfer pricing documentation, assistance with excise tax filings, and advice on foreign and domestic tax related matters. “All Other” fees consisted of information security vendor assessments, licenses for accounting software, and other permissible services that do not fall into the three categories listed above.

Executive compensation

PROPOSAL

Advisory Approval of Executive Compensation ●Approve, on an advisory basis, the compensation of our Named Executive Officers. ●Our executive compensation program appropriately aligns our executives’ compensation with the performance of the Company and its business units as well as their individual performance.

Section 14A of the Securities Exchange Act provides our stockholders with the opportunity to approve, on an advisory basis, the compensation of our named executive officers as described in this Proxy Statement. This is the eighth year that the Company is asking stockholders to vote on this type of proposal, known as a “say-on-pay” proposal.

We believe that our executive compensation program is consistent with our core compensation principles and is structured to assure that those principles are implemented. At the Annual Meeting of Stockholders held on May 8, 2018, approximately 93 percent of the votes cast on this issue voted to approve the compensation of the Company’s named executive officers as disclosed in last year’s Proxy Statement. Although the vote was non-binding, the Compensation Committee believes this level of approval percentage indicates that our stockholders strongly support our core compensation principles and our executive compensation program, and we believe our stockholders as a whole should support them as well.

Thus, the Company is submitting to stockholders the following resolution for their consideration and approval:

“RESOLVED, that the stockholders approve, on an advisory basis, the compensation of the Company’s Named Executive Officers as disclosed in this Proxy Statement pursuant to the compensation disclosure rules of the Securities and Exchange Commission (including in the Compensation Discussion and Analysis, the accompanying compensation tables and related narrative).”

We encourage you to read the entire Compensation Discussion and Analysis portion of this Proxy Statement to learn more about our executive compensation program and the impact that our financial performance has on the annual and long-term incentive compensation earned by our leadership team.

While the Board of Directors and the Compensation Committee intend to carefully consider the results of the voting on this proposal when making future decisions regarding executive compensation, the vote is not binding on the Company or the Board and is advisory in nature. The Company currently holds advisory votes on the compensation of named executive officers annually. Accordingly, the next such advisory vote is expected to occur at the 2020 Annual Meeting.

RECOMMENDATION OF THE BOARD

The Board of Directors unanimously recommends a vote  “FOR”  this proposal for the reasons discussed above. Proxies solicited by the Board of Directors will be voted  “FOR”  this proposal unless a stockholder indicates otherwise in voting the proxy.

Section I: Executive Summary

Selected 2018 Financial Performance and Business Highlights

3M’s 2018 financial performance was achieved through growth and disciplined execution. Given the impact that the Net TCJA Transition Tax, the Water Quality and Sustainability Grant, and the Net CMD Divestiture Gains, had on the Company’s 2018 financial performance, our results are shown below both as determined in accordance with GAAP (to the extent applicable) and excluding these three impacts.

See Appendix A to this Proxy Statement for a reconciliation of earnings per share, operating margin performance, free cash flow and free cash flow conversion to our results for the most directly comparable financial measures as reported under generally accepted accounting principles in the United States, and the calculation of return on invested capital.

We believe that our ability to deliver consistent results over time is reflected in our total stockholder return, which was in the top half of our executive compensation peer group for the three- and five-year periods ending on December 31, 2018. For additional information, see “Total Stockholder Return” on page 50 of this Proxy Statement.

Other noteworthy accomplishments include the following:

●	Announced the acquisition of M*Modal to strengthen our Health Information Systems portfolio and complement organic growth;
●	Awarded a record total of 4,208 patents from patent offices around the world in 2018, including 688 patents granted to 3M by the United States Patent and Trademark Office, which brings to more than 117,000 the total number of patents awarded to 3M in its corporate history;
●	Strengthened our portfolio going forward by completing the divestiture of substantially all of our Communication Markets Division;
●	Successfully completed the rollout of the enterprise resource planning (ERP) system in the United States – approximately 70 percent of global revenues are now on the new ERP system;
●	Over 100 consecutive years of paying dividends to stockholders and 60 consecutive years of annual increases;
●	Returned $8.1 billion to stockholders via dividends and gross share repurchases; and
●	Recognized by Ethisphere® as one of the World’s Most™ Ethical Companies® for the sixth consecutive year.

Factors Creating Alignment Between Pay and Performance

3M’s executive compensation program is designed to maintain a strong alignment between corporate performance and executive compensation by tying incentive compensation to the achievement of performance metrics that we believe increase the Company’s long-term value. For 2018, highlights of the program include:

●	A large portion of each executive’s target Total Direct Compensation (cash plus long-term incentives) is performance-based, varying from 89 percent for Chief Executive Officer Michael Roman to a range of 82-91 percent for the other Named Executive Officers; and
●	The incentive compensation opportunities provided to the Named Executive Officers utilize multiple performance-based metrics focused primarily on revenue and earnings performance, increase in 3M’s common stock price, efficient use of capital, and free cash flow conversion.

Impact of Company Performance on Incentive Compensation and Real Pay Delivery

One objective of our incentive compensation program is to align our Named Executive Officers’ real pay delivery with performance. The Company’s performance directly impacted incentive compensation pay outcomes for our Named Executive Officers as follows:

2018 Annual Incentive Compensation

For the Named Executive Officers paid on the basis of the Company’s overall performance, the 2018 annual incentive compensation payout (before any adjustment for individual performance) was 95 percent of the target amount. The payouts reflect our performance against the goals established for 2018 (as shown below) and were calculated excluding the impact of the Net TCJA Transition Tax and a related $600 million pension contribution made in 2017, the Net CMD Divestiture Gains and the Water Quality and Sustainability Grant.

●	Local currency sales achieved 98 percent of plan;
●	3M economic profit achieved 96 percent of plan; and
●	3M’s 2018 economic profit represented 103 percent of its 2017 results.

Performance Share Awards (Long-Term Incentive Compensation)

Based on the results described below, the number of shares (excluding dividend equivalents) delivered pursuant to the performance share awards issued to the Named Executive Officers for the 2016-2018 performance period equaled 105 percent of the target number of shares awarded. After considering the appreciation in the price of 3M’s common stock over the three-year performance period and the additional shares delivered pursuant to the dividend equivalent rights granted as part of the awards, the value of the total number of 3M shares delivered to the Named Executive Officers in settlement of these awards (determined using the closing price of a share of 3M common stock on the NYSE for December 31, 2018) equaled 134 percent of the value of the target number of performance shares subject to such awards (determined using the closing price of a share of 3M common stock on the NYSE for March 1, 2016, the initial grant date of 2016 performance share awards).

Stock and Long-Term Incentive Compensation

The performance of 3M’s stock has a material impact on the amount of compensation actually realized by our Named Executive Officers. Our stock ownership guidelines require covered executives, including the Named Executive Officers, to own amounts of Company stock having a value exceeding a specified multiple of their base salary. If the market price of 3M’s stock declines, so does the value of the stock they own.

Similarly, stock options and other long-term incentive awards held by our Named Executive Officers increase or decrease in value along with increases and decreases in the value of 3M’s common stock. The stock options and other long-term incentive compensation granted to our Named Executive Officers in years prior to 2018 decreased in value during 2018 as the closing price for a share of the Company’s common stock on the NYSE decreased from $235.37 on December 29, 2017, to $190.54 on December 31, 2018.

2018 Say on Pay

In 2018, approximately 93 percent of the votes cast on our say-on-pay proposal approved the compensation of our Named Executive Officers as disclosed in last year’s Proxy Statement. Although the vote was non-binding, the Committee believes this level of approval indicates that stockholders strongly support our executive compensation programs and policies. The Committee will consider the results of this year’s say-on-pay proposal, as well as feedback from our stockholders, when making future executive compensation decisions.

Noteworthy Compensation Program Actions for 2018

During 2018, 3M and the Committee took the noteworthy actions described below as part of the Company’s executive compensation program.

●	Approved new compensation terms for Michael F. Roman in connection with his appointment as Chief Executive Officer, including an annual base salary of $1,200,000 and target annual incentive compensation of $3,120,000, each of which were prorated for 2018. The Compensation Committee (with ratification by the independent members of the Board) will determine the target value of Mr. Roman’s annual long-term incentive grants each year based on market data and his individual performance. Mr. Roman also received special promotion performance share and stock option awards granted at the time of his appointment as Chief Executive Officer that had an aggregate target grant value of $2,500,000, as described in more detail on page 62). Consistent with the Company’s compensation philosophy, Mr. Roman does not have an employment agreement, severance agreement or change in control agreement.
●	Approved new compensation terms for Inge G. Thulin in connection with his appointment as Executive Chairman, including an annual base salary of $1,000,000 and target annual incentive compensation of $1,500,000 (each prorated for 2018), which represent decreases of approximately 35 percent and 39 percent, respectively. The Compensation Committee (with ratification by the independent members of the Board) will determine the target value of Mr. Thulin’s annual long-term incentive grants each year based on market data and his individual performance. In anticipation of his transition to Executive Chairman in 2018, the aggregate target compensation value for Mr. Thulin’s 2018 long-term incentive compensation awards was reduced by $3,000,000 from the target compensation value established for such awards granted to him in 2017. Mr. Thulin also received a performance share award granted at the time of his appointment as Executive Chairman that had a target grant value of $750,000 (as described in more detailed on page 62). Mr. Thulin’s new compensation terms were approved by the Committee (with ratification by the independent members of the Board) consistent with the recommendation of its independent compensation consultant based on peer and other market data.
●	Expanded the scope of our clawback policy to address situations involving significant financial or reputational harm. For additional information concerning our updated policy, please refer to the section entitled “Clawback Policy” on page 66 of this Proxy Statement.

Compensation Policies and Practices

Our compensation program is designed to provide appropriate performance incentives and avoid compensation practices that do not promote the interests of our stockholders.

Section II: How We Determine Executive Compensation

Principles

The Company maintains global compensation principles that are intended to ensure that its compensation practices are fair and reasonable as applied to both executive and non-executive employees. These principles align with the Company’s vision and strategies, balance both individual and enterprise-wide performance and seek to provide competitive wages and benefits with consistent positioning in the median range of the most-relevant markets to employees based on roles, responsibilities, skills and performance. 3M also believes that the compensation of its executives should be closely tied to the performance of the Company, so that their interests are aligned with the interests of long-term 3M stockholders. Consistent with this philosophy, the following core principles provide a framework for the Company’s executive compensation program:

●	Total Direct Compensation should be competitive to attract the best talent to 3M, motivate executives to perform at their highest levels, reward individual contributions that improve the Company’s ability to deliver outstanding performance, and retain those executives with the leadership abilities and skills necessary for building long-term stockholder value;
●	The portion of Total Direct Compensation that is performance-based and is, therefore, at risk should increase with the level of an individual’s responsibility;
●	The program should balance incentives for delivering outstanding long-term, sustainable performance against the potential to encourage inappropriate risk-taking;
●	The metrics and targets for earning performance-based incentives should be consistent with, and aligned to, increasing stockholder value over the long term; and
●	A significant portion of each executive’s personal net worth should be tied to the value of 3M common stock as further motivation to build long-term stockholder value and mitigate the risk of inappropriate risk-taking.

To monitor and support the effectiveness of this program, the Committee periodically reviews the compensation principles used for setting annual total cash compensation for the Company’s global workforce and approves the methodology for determining annual long-term incentive target grant values for employees eligible to receive such awards. The Company also periodically compares its pay components to those of other premier companies and adjusts them as necessary to stay competitive and attract, retain and motivate a highly qualified, diverse workforce at all levels throughout the organization, not just for its executives.

Roles and Responsibilities

The Company believes that a collaborative process best ensures that compensation decisions reflect the principles of our executive compensation program. Set forth below is a summary of the roles and responsibilities of the key participants that were involved in making decisions relating to the compensation that our Named Executive Officers earned in 2018.

Executive compensation Compensation discussion and analysis

BASE SALARY

Percentage of Target 2018 Total Direct Compensation:
CEO – 11%
Other NEOs – 15%

3M pays each of its executives a base salary in cash on a monthly basis. The amount of this base salary is reviewed at least annually and does not vary with the performance of the Company. Base salaries are designed to compensate the executives for their normal day-to-day responsibilities, and it is the only component of their compensation that is considered to be fixed rather than variable in nature.

ANNUAL INCENTIVE

Percentage of Target 2018 Total Direct Compensation:		Performance Metrics and Weighting:
CEO – 15% Other NEOs – 13%		●50% Local Currency Sales (of 3M or a business unit, as applicable) vs. Plan ●20% Economic Profit (of 3M or a business unit, as applicable) vs. Plan ●30% Economic Profit of 3M vs. Prior Year

3M provides its executives with annual incentive compensation through plans that are intended to align a significant portion of their Total Cash Compensation with the financial performance of the Company and its business units. Each executive is assigned a target amount of annual incentive compensation as part of his or her target Total Cash Compensation, but the amount of annual incentive compensation actually paid depends on the performance of 3M and its relevant business units as well as each executive’s individual performance.

3M’s AIP offers eligible employees an opportunity to earn short-term incentive compensation based on three performance metrics, which were weighted for 2018 as indicated above. All 2018 performance targets for our Corporate AIP plan were set at or above 2017 results.

The actual amount paid to an eligible employee for a particular year may range from 0 percent to 200 percent of the employee’s target amount for that year, depending on the performance of the Company and its business units compared to the performance goals approved by the Compensation Committee. The amount of annual incentive compensation paid to an eligible employee also may be increased (up to 30 percent), reduced or eliminated entirely based on the employee’s individual performance during that year. Individual performance takes into account both quantitative (financial results, for example) and qualitative (market and economic circumstances, for example) factors. In no event, however, may the total amount paid to an eligible employee exceed 200 percent of the employee’s target amount for the year.

In determining the amount of annual incentive compensation paid to a Named Executive Officer, the Named Executive Officer’s individual performance is considered based upon the annual performance evaluation that Mr. Roman, assisted by 3M’s Senior Vice President, Human Resources, and other Company employees, completed for each Named Executive Officer (other than himself and Mr. Thulin) and the annual performance evaluation that the Compensation Committee (acting through its Chairman) completed for each of Mr. Roman and Mr. Thulin. These performance evaluations are done according to 3M’s overall performance assessment and management processes, which involve setting annual financial and non-financial goals and objectives for each individual and then assessing the individual’s overall performance against these goals and objectives at the end of the year. While the annual incentive compensation earned by eligible 3M employees generally is determined under the AIP, the annual incentive compensation earned during 2018 by the senior executives whose compensation is decided by the Committee (including all of the Named Executive Officers) was determined under the Executive Plan approved by 3M’s stockholders at the 2007 Annual Meeting. A total of 19 senior executives participated in this Executive Plan during 2018. The Company utilizes the Executive Plan to provide performance-based compensation that is intended to be exempt from the $1 million annual deduction limit of state tax laws that are similar to Section 162(m) of the Internal Revenue Code, as in effect prior to the Tax Cuts and Jobs Act of 2017.

Assuming the Company meets the Adjusted Net Income goal, the Executive Plan provides the Committee with discretion to determine the amount of annual incentive compensation paid to 3M’s Named Executive Officers and its other senior executives. The Executive Plan establishes a maximum amount of annual incentive compensation that may be earned by each covered executive for a year (a percentage of the Company’s Adjusted Net Income for such year) and then the Committee utilizes this discretion to pay each covered executive less than this maximum amount based on such factors as it deems relevant. Since the Executive Plan was first adopted in 2007, the Committee has rarely used this discretion to pay a covered executive (other than our Chief Executive Officer) anything other than the same amount such executive would have received had he or she been participating in the broad-based AIP (including the individual performance multiplier).

LONG-TERM INCENTIVES

Percentage of Target 2018 Total Direct Compensation:		Performance Metrics and Weighting:
CEO – 37% Stock Options		●20% Earnings per Share Growth
37% Performance Shares		●40% Relative Organic Volume Growth
Other NEOs – 36% Stock Options		●20% Return on Invested Capital
36% Performance Shares		●20% Free Cash Flow Conversion

3M provides long-term incentive compensation to its executives through an incentive plan approved by the Company’s stockholders. This is a typical omnibus-type plan that authorizes the Committee to grant stock options, restricted stock, restricted stock units, stock appreciation rights, performance shares, and other stock awards to employees of the Company and its subsidiaries. The Company provides its executives with this long-term incentive compensation based on 3M common stock in order to effectively motivate such executives to build long-term stockholder value.

In determining the performance-adjusted target grant value of the stock options and performance shares provided to our Named Executive Officers, the Compensation Committee considers the individual performance of our Named Executive Officers using the performance evaluations described under “Annual Incentive” above.

Our Named Executive Officers also may receive special equity awards on an ad hoc basis as new hires or for recognition and retention, promotions, or other purposes.

Benefits and Perquisites

The Company’s Named Executive Officers participate in the same health care, disability, life insurance, pension, and 401(k) benefit plans available to most of the Company’s U.S. employees. They also are eligible to receive certain additional benefits and perquisites that are provided for the convenience (financial planning assistance and meals when attending to 3M business, for example), financial security (nonqualified deferred compensation plans and premiums for additional life insurance coverage, for example), personal security (home security equipment/monitoring, for example) or personal health (on-site exercise facilities and physical exams, for example) of the executives. Our Named Executive Officers and other employees also may receive Company tickets for sporting or other events. The Company believes that the benefits and perquisites offered generally are similar to those of our peers and assist in attracting and retaining executives. In some cases, there is no incremental cost to the Company associated with providing these additional benefits and perquisites (physical exams and certain tickets to events, for example) or the executives pay all or a substantial portion of the incremental costs incurred by the Company (on-site exercise facilities, for example).

3M generally provides these additional benefits and perquisites to a group of approximately 90 of our most senior U.S. employees on a consistent basis, although enhanced personal security equipment and monitoring is provided only to our Chief Executive Officer and the type of additional life insurance coverage provided varies based on the date the executive was first appointed to an executive position. Individuals first appointed to an executive position on or before August 31, 2003, receive additional life insurance coverage that is provided through a universal life insurance policy. Individuals first appointed on or after September 1, 2003, including our Chief Executive Officer, receive group term life insurance coverage.

The Company also operates aircraft that are used by our senior officers and other employees to conduct company business. For personal security reasons, the Board of Directors requires our Chief Executive Officer to use the Company’s aircraft for all air travel, both business and personal. Our Chief Executive Officer’s spouse and other guests also may accompany him on flights.

The incremental cost to the Company of providing these additional benefits to the Named Executive Officers is reflected in the All Other Compensation Table. No tax gross-ups are provided on any of these additional benefits and perquisites. Except as described above, the entire program applied to approximately 90 members of our U.S. senior management during 2018, including all of the Named Executive Officers.

Competitive Pay

We compete for executive talent in a global market. In order to ensure that we are providing Total Direct Compensation that is competitive, the Committee annually conducts a rigorous benchmarking process with the help of its independent compensation consultant, FW Cook. During this process, the Committee generally considers available pay data for two peer groups: an executive peer group and a survey peer group.

The Committee, with assistance from its independent compensation consultant, periodically reviews the composition of the executive peer group to determine whether any changes are appropriate. Following its review in 2018, the Committee determined that no changes were needed at that time.

The Company receives pay data and information on the executive compensation practices at the companies in 3M’s executive peer group from Aon and FW Cook.

Survey Peer Group

For 2018, there were approximately 200 comparator companies in the survey peer group. Although the number and identity of the companies varies from year to year and from survey to survey, each of the companies included in the survey peer group had annual revenue exceeding $10 billion. All of the companies in the survey peer group also participate in one or more executive compensation surveys obtained from three consulting firms (Aon, FW Cook, and Willis Towers Watson). Pay data for the survey peer group is statistically regressed to recognize the different sizes of the comparator companies (based on annual revenues) as compared to the size of 3M. The Committee does not review the identity of the companies in the survey peer group.

How the Committee Establishes Target Compensation Levels Using Competitive Pay Data

The Committee considers the pay data from the Peer Groups as a reference point when establishing the target Total Cash Compensation and the initial target value of long-term incentive compensation to be provided to our executives in any given year before consideration of individual performance. For each Named Executive Officer, the Committee generally tries to set such amounts between 80 and 120 percent of the median for the corresponding items of compensation provided to similarly situated executives in the executive peer group. In situations where the Committee believes that there is insufficient market data for one or more positions, the Committee starts with the median amount for a similar position and adjusts that amount up or down (generally not more than 15 percent) to arrive at a number that it uses as the “median” for that position. The final target amounts established by the Committee for each executive may vary based on individual circumstances. When setting the target amounts for any individual executive, the Committee may consider the breadth and complexity of the executive’s duties and responsibilities, the scores assigned to the executive for his or her leadership behaviors (e.g., customer focus, strategic mindset, operational leadership), the financial and operational performance of the business activities for which the executive is responsible, experience and time in their current position, internal pay equity, individual performance, and such other factors as the Committee determines to be appropriate. The pay data for the survey peer group is used by the Committee to assess the reasonableness of the benchmarking results for each executive position benchmarked, helping to ensure that the Company’s compensation objectives are being met.

The Committee also uses information on the executive compensation practices at companies in the executive peer group when considering design changes to the Company’s executive compensation program. Overall, the Company believes that use of this information from the Peer Groups enables the Committee to create better alignment between executive pay and performance and to help ensure that 3M can attract and retain high-performing executive leaders.

Tally Sheets

The Committee periodically reviews a report comparing the amounts of compensation actually received by the Company’s Named Executive Officers to the amounts reported in its annual proxy statement and summarizing the compensation that would be owed to such individuals in the event of the termination of their employment under various circumstances. Reviewing this report helps the Committee better understand the Company’s potential obligations to the Named Executive Officers following the termination of their employment. It also helps the Committee better assess the risk of any of the Named Executive Officers leaving the Company prematurely because the Company is not providing sufficient retention incentives.

Tax Considerations

Section 162(m) of the Internal Revenue Code of 1986, as amended (“Section 162(m)”), disallows a tax deduction to public companies for compensation paid in excess of $1 million to “covered employees” (generally, a company’s chief executive officer and its three other highest paid executive officers other than its chief financial officer). Prior to enactment of the TCJA, there was an exception to this $1 million limitation for performance-based compensation if certain requirements set forth in Section 162(m) and the applicable regulations were met. The Committee has historically designed its compensation programs based on its belief that a substantial portion of the compensation payable to NEOs should be based on the achievement of performance-based targets or otherwise be designed with the intent that such compensation qualifies as deductible performance-based compensation under Section 162(m). As a result, annual incentive compensation and certain equity-based compensation arrangements granted to our covered employees in prior years were intended to qualify as performance-based compensation under Section 162(m).

Effective for taxable years beginning after December 31, 2017, the TCJA amended Section 162(m) to eliminate the exception for performance-based compensation and expand the definition of “covered employee” to include a company’s chief financial officer and certain individuals who were covered employees in years other than the then-current taxable year. Interpretations of and changes in applicable tax laws and regulations as well as other factors beyond the control of the Committee can affect deductibility of compensation, and there can be no assurance that compensation paid to our executive officers who are considered covered employees for purposes of Section 162(m) will be deductible.

The Committee will continue to consider tax implications (including the potential lack of deductibility under Section 162(m)) when making compensation decisions but reserves the right to make compensation decisions based on other factors if the Committee believes it is in the best interests of the Company and its stockholders to do so. The Committee also reserves the right to make changes or amendments to existing compensation programs, including changes or amendments that are intended to modify or eliminate aspects of such arrangements that were intended to take advantage of the former exception to Section 162(m) for performance-based compensation but that the Committee no longer believes are in the best interests of the Company and its stockholders.

Section III: How We Paid Our Named Executive Officers in 2018

2018 Base Salary and Target Total Cash Compensation

The Committee considers changes in the base salaries and target Total Cash Compensation of the Named Executive Officers at least annually. As part of its normal process to progress senior executives to a level of compensation that is commensurate with their responsibilities, the Committee also periodically considers adjustments to the base salaries and target Total Cash Compensation of senior executives whose rate of pay is set below the market median. All adjustments are made only after considering the most recent compensation data available to the Committee for executives with similar responsibilities at companies in the Peer Groups, each individual’s place in the salary range for his or her position, and the individual’s job performance.

In February 2018, the Committee approved the increases in the base salaries and target Total Cash Compensation shown below for the Named Executive Officers following completion of their annual performance evaluations. No changes were made to Mr. Roman’s or Mr. Thulin’s base salary or target Total Cash Compensation at that time.

Name		Previous Base Salary ($)		New Base Salary Effective 4/1/18 ($)		% Increase		Previous Target Total Cash Compensation ($)		New Target Total Cash Compensation Effective 4/1/18 ($)		% Increase
Nicholas C. Gangestad		799,495		841,495		5%		1,598,990		1,682,989		5%
Hak Cheol Shin		875,000		892,500		2%		1,750,000		1,785,000		2%
Julie L. Bushman		769,672		800,502		4%		1,424,000		1,481,040		4%
Frank R. Little		697,409		739,952		6%		1,290,304		1,369,015		6%
James L. Bauman		731,188		760,477		4%		1,352,800		1,406,988		4%

As a result of these increases, the target Total Cash Compensation of these Named Executive Officers ranged from 97 percent to 108 percent of the median value of the corresponding compensation provided to executives with similar responsibilities at companies in the executive peer group.

In May 2018, the Committee approved the adjustments in base salary and target Total Cash Compensation shown below in connection with Mr. Roman’s appointment to Chief Executive Officer and Mr. Thulin’s appointment to Executive Chairman. The adjustments were intended to better align the target Total Cash Compensation of each executive with the breadth of the responsibilities that accompany their new roles.

Name		Previous Base Salary ($)		New Base Salary Effective 7/1/18 ($)		% Increase		Previous Target Total Cash Compensation ($)		New Target Total Cash Compensation Effective 7/1/18 ($)		% Increase
Michael F. Roman		900,000		1,199,952		33%		2,000,000		3,120,000		56%
Inge G. Thulin		1,538,400		1,000,000		-35%		4,000,000		2,500,000		-38%

As a result of these adjustments, Mr. Roman’s target Total Cash Compensation was approximately 83 percent of the median value of the corresponding compensation provided to executives with similar responsibilities at companies in the executive peer group. Mr. Thulin’s adjustment to target Total Cash Compensation reflects a decrease of 38 percent from his final compensation as Chief Executive Officer, which the Committee’s independent compensation consultant recommended to align with median market practice.

Executive compensation Compensation discussion and analysis

2018 Annual Incentive

During 2018, the Committee provided the Named Executive Officers with the opportunity to earn short-term incentive compensation under the Executive Plan. Each Named Executive Officer’s target annual incentive for the year was equal to the difference between his or her target Total Cash Compensation and annual base salary. Each of the Named Executive Officers was assigned to an appropriate business unit (the entire Company, in some cases) established under the AIP for the purpose of measuring business performance during 2018 and converting that performance into a payout determined in accordance with the terms of the AIP. While none of the Named Executive Officers are covered by the AIP, the Committee rarely uses its discretion under the Executive Plan to pay the covered executives (other than our Chief Executive Officer) anything other than the same amount such executive would have received had he or she been participating in the AIP (including the individual performance multiplier).

The amounts payable under the AIP for 2018 were based on the following performance results for the Company and, as applicable, the respective business units to which the Named Executive Officers were assigned for all or part of the year:

		Local Currency Sales (50%)						Economic Profit (20%)						Total 3M Economic Profit vs. Prior Year (30%)						Weighted Average Payout % Based On Payout Curve
(Dollar Amounts in Millions) Business Unit		Plan		Actual		Actual vs. Plan		Plan		Actual		Actual vs. Plan		Prior Year		Actual		Actual vs. Prior Year
Total Company		33,514		32,869		98%		5,590		5,348		96%		3,648		3,752		103%		95%
International Operations		20,374		20,009		98%		3,539		3,507		99%		3,648		3,752		103%		96%
Safety and Graphics Business Group		6,889		6,830		99%		1,264		1,217		96%		3,648		3,752		103%		97%
Industrial Business Group		12,428		12,232		98%		2,053		1,876		91%		3,648		3,752		103%		92%

Since the Company satisfied the Executive Plan’s performance objective by earning Adjusted Net Income of $6.0 billion for 2018, the plan authorized the Committee to approve payments of annual incentive compensation to each Named Executive Officer equal to a maximum of one-quarter of one percent of such Adjusted Net Income ($15 million), subject to the Committee’s negative discretion to pay each covered executive any amount less than this maximum based on such factors as it deems relevant, including the goals set forth under the AIP. At its meeting in February 2019 and consistent with its past practice, the Committee approved (and with respect to Mr. Roman and Mr. Thulin, the independent members of the Board of Directors ratified) a payment to each executive equal to the amount such executive would have received had he been participating in the broad-based AIP (including the individual performance multiplier).

Name		Target 2018 Annual Incentive* ($)		Actual 2018 Annual Incentive ($)		Payout as a % of Target
Michael F. Roman		1,510,024		1,431,503		95%
Inge G. Thulin		1,980,800		1,877,798		95%
Nicholas C. Gangestad		830,995		787,783		95%

Frank R. Little		305,489		294,804		97%
James L. Bauman		640,286		590,984		92%

*	These amounts are prorated to reflect the increases in Total Cash Compensation described above that resulted in corresponding increases in each individual’s target annual incentive compensation.

Long-Term Incentives — 2018 Annual Grants

After considering the most recent long-term incentive compensation data available from companies in the Peer Groups and after taking into account its evaluation of their individual performance during 2017 and Mr. Thulin’s anticipated transition to Executive Chairman during the second half of 2018, the Committee approved (and in the case of Mr. Thulin, the independent members of the Board of Directors ratified) the following performance-adjusted target compensation values for the Named Executive Officers’ 2018 long-term incentive compensation awards. For ease of comparison, the table below also shows the performance-adjusted target compensation values of the Named Executive Officers’ 2017 long-term incentive compensation awards.

Name		Performance- Adjusted Target Grant Value of 2017 Annual Awards ($)				Performance- Adjusted Target Grant Value of 2018 Annual Awards ($)
Michael F. Roman			2,455,580				4,720,000
Inge G. Thulin			12,000,000				9,000,000
Nicholas C. Gangestad			3,677,700				4,673,500
Hak Cheol Shin			2,393,150				3,954,500
Julie L. Bushman			1,847,830				2,913,400
Frank R. Little			2,913,400				3,496,080
James L. Bauman			2,268,290				2,836,403

Consistent with market practices at companies in the Peer Groups, during 2018, the Committee chose to deliver one-half of the performance-adjusted target grant value of the annual long-term incentive compensation awards provided to 3M’s Named Executive Officers (other than Mr. Thulin) in the form of stock options and the remaining one-half in the form of performance shares. Mr. Thulin’s awards were delivered approximately 67 percent in the form of stock options and 33 percent in the form of performance shares in light of the anticipated changes in his duties and responsibilities.

2018 Stock Options

Stock options granted to the Named Executive Officers in 2018 as part of their long-term incentive compensation have the following features:

●	an exercise price equal to the closing price of a share of 3M common stock on the NYSE for the date of grant;
●	a ratable three-year vesting schedule; and
●	a maximum term of 10 years.

2018 Performance Share Awards

Performance shares awarded in 2018 will result in the issuance of actual shares of 3M common stock to 3M’s Named Executive Officers if the Company achieves certain financial goals over the years 2018, 2019, and 2020. The number of shares of 3M common stock that will be issued for each 2018 performance share is linked to the Company’s performance as measured by the criteria of Earnings per Share Growth (20 percent weighting), Relative Organic Volume Growth (40 percent weighting), Return on Invested Capital (20 percent weighting), and Free Cash Flow Conversion (20 percent weighting). These performance criteria were selected because they are aligned with 3M’s operating plan and the financial objectives communicated to stockholders and the Committee believes that they are important drivers of long-term stockholder value. Attainment of these four independent performance criteria is measured separately for each calendar year during the three-year measurement period, with each year weighted as follows: 2018 — 50 percent; 2019 — 30 percent; and 2020 — 20 percent. However, the formulas by which the Company’s performance is measured do not change over the three-year performance period.

2019 Proxy Statement

Table of Contents

Executive compensation Compensation discussion and analysis

The actual number of shares of 3M common stock that will be delivered at the end of the three-year performance period ending on December 31, 2020, may be anywhere from 0 percent to 200 percent of the target number of performance shares awarded, depending on the performance of the Company during the performance period. However, an executive may forfeit all or a portion of such shares if he or she does not remain employed by the Company throughout the three-year performance period.

For awards tied to the achievement of performance goals over the years 2018, 2019, and 2020, the Committee approved the following formulas for determining the number of shares of 3M common stock to be delivered for each performance share awarded, with the total number of shares actually delivered being the sum of the number of shares earned as a result of the Company’s achievement of each of the four financial goals. In the event that the Company’s performance as measured by any of these performance criteria falls between any of the percentages listed below, the number of shares of 3M common stock earned will be determined by linear interpolation.

The above formulas are not a prediction of how 3M will perform during the years 2018 through 2020 or any other period in the future. The sole purpose of these formulas, which were approved by the Committee in February 2018, is to establish a method for determining the number of shares of 3M common stock to be delivered for the performance share awards described above. 3M is not providing any guidance, nor updating any prior guidance, of its future performance with the disclosure of these formulas, and you are cautioned not to rely on these formulas as a prediction of 3M’s future performance.

Long-Term Incentives — Other Grants

In connection with the changes in Mr. Roman’s and Mr. Thulin’s roles and responsibilities and after consulting with its independent compensation consultant and considering each executive’s existing compensation packages and other factors, the Committee approved (and the independent members of the Board of Directors ratified) a performance share award for each of Mr. Roman and Mr. Thulin with a target grant value of $1,250,000 and $750,000, respectively, and a stock option grant for Mr. Roman with a target grant value of $1,250,000, in each case, effective as of July 1, 2018. The terms and conditions of the grants were the same as those of the 2018 annual grants described in the section entitled “Long-Term Incentives — 2018 Annual Grants” beginning on page 61 of this Proxy Statement.

Long-Term Incentives — All Outstanding Performance Share Awards

The Company’s annual award cycle and three-year performance periods result in an overlap of awards. For example, the performance goals for 2018 performance share awards relate to the years 2018, 2019, and 2020. Similarly, the performance goals for 2017 performance share awards relate to the years 2017, 2018, and 2019, and so on, as shown below. Performance against the goals established for each award are measured separately for each calendar year during the measurement period, with each year weighted as shown below in parenthesis. The Committee believes this structure reduces motivation to maximize performance in any one period by providing the highest-level rewards only by building sustainable long-term results.

*	The amounts in this column reflect the number of shares accrued (excluding dividend equivalents) based on, among other things, Worldwide IPI for the 2018 calendar year, as reported by Global Insights on January 15, 2019, and a deemed earnings per share for 2017 equal to $9.17, which represents the earnings per diluted share for the Company’s 2017 fiscal year, as determined in accordance with GAAP and excluding the impact of the Net TCJA Transition Tax. The final number of shares accrued may vary in the event of changes in Worldwide IPI reported by Global Insights or, in the case of 2017 performance share awards, the use of a different earnings per share number for the Company’s 2017 fiscal year. Due to rounding, the numbers shown in this column may not equal the result obtained by multiplying the Performance Shares Awarded by the Shares Accrued Per Performance Share Based on 2018 Performance.
**	Represents the closing price of a share of 3M common stock on the NYSE for December 31, 2018 ($190.54), multiplied by the actual number of shares accrued (before rounding and excluding dividend equivalents) based on the Company’s 2018 performance.
***	In accordance with the terms of the award, the target number of performance shares subject to Mr. Little’s 2018 performance share award were reduced based on his July 1, 2018, retirement. Prior to this reduction, the target number of performance shares subject to Mr. Little’s 2018 performance share award was 7,557.

Although shares of 3M common stock are accrued annually for each outstanding performance share award, an executive may forfeit all or a portion of the shares otherwise issuable pursuant to his or her award if he or she does not remain employed by the Company throughout the entire three-year performance period.

In accordance with the terms of the stock ownership guidelines, the number of shares required to be beneficially owned by each Named Executive Officer (other than Mr. Roman) in order to maintain compliance was most recently recalculated as of December 31, 2016, using the closing price of a share of 3M common stock on the NYSE for December 30, 2016. Although each such Named Executive Officer has until December 31, 2019, to acquire beneficial ownership of any additional shares required as a result of the recalculation, each individual beneficially owned a sufficient number of shares on December 31, 2018, to comply with the new ownership levels required.

**

As a result of his appointment to the position of Chief Executive Officer, Mr. Roman’s required level of ownership increased, effective July 1, 2018, from a multiple of three times his annual base salary to a multiple of six times his annual base salary. Although Mr. Roman has until June 30, 2023, to acquire beneficial ownership of any additional shares required as a result of the recalculation, he beneficially owned a sufficient number of shares on December 31, 2018, to comply with the new ownership level required.

The stock ownership guidelines provide that the number of shares required to be beneficially owned by each covered executive will be calculated using such executive’s annual base salary at the time of his or her initial appointment to a Section 16 position and again at the time of a position change from one multiple level to another multiple level, and the fair market value of 3M common stock at that time. The guidelines also provide that the number of shares required to be beneficially owned by each executive will be recalculated every three years using his or her annual base salary and the fair market value of 3M common stock at the recalculation date. Pursuant to the terms of the guidelines, the next periodic recalculation date is scheduled to occur on December 31, 2019.

Each covered executive is expected to attain beneficial ownership of the number of shares of 3M stock determined by the guidelines within five years of his or her initial appointment to a position covered by the guidelines or a position change from one multiple level to another multiple level. The guidelines also provide that each covered executive whose required level of ownership increases as a result of a periodic recalculation will have three years from the recalculation date (or the balance of the five-year period since the date of their initial appointment or latest position change, if longer) to acquire beneficial ownership of any additional shares required as a result of the recalculation. However, if a covered executive is not making adequate progress to meet the required level of ownership within the applicable time period, the guidelines provide that he or she will be required to hold and not sell a sufficient number of the after-tax 3M shares received upon the next payout of performance shares to be on track to satisfy the required ownership level.

For purposes of these guidelines, shares owned directly by a covered executive or by members of the covered executive’s immediate family, shares owned indirectly through a covered executive’s account in the Company’s 401(k) plan or another deferred compensation plan, outstanding shares of restricted stock owned by a covered executive, and shares represented by outstanding restricted stock units granted to a covered executive are all considered to be beneficially owned by the covered executive and are counted in determining attainment of the required beneficial ownership level.

For more information concerning the 3M stock ownership of the Named Executive Officers, see the section entitled “Security Ownership of Management” beginning on page 85 of this Proxy Statement.

Prohibition of Hedging and Pledging

The Company’s stock trading policies prohibit the Company’s executive officers from (1) purchasing any financial instrument that is designed to hedge or offset any decrease in the market value of the Company’s common stock, including prepaid variable forward contracts, equity swaps, collars, and exchange funds; (2) engaging in short sales related to the Company’s common stock; (3) placing standing orders; (4) maintaining margin accounts; and (5) pledging 3M securities as collateral for a loan. All transactions in 3M securities by directors and executive officers must be pre-cleared with the Company’s Deputy General Counsel.

Clawback Policy

In 2018, the Board of Directors updated the Company’s clawback policy to address situations involving significant financial or reputational harm. Pursuant to the terms of the revised policy, the Board of Directors is authorized to require reimbursement of certain cash and equity compensation provided to an executive if (1) 3M is required to make a material restatement of its financial statements, whether or not the result of misconduct by the executive of any other individual, (2) the executive commits an act of misconduct that has or might reasonably be expected to cause significant financial or reputational harm to the Company or (3) the executive fails to identify, escalate, monitor or manage, in a timely manner and as reasonably expected, risks material to the Company, which have or might reasonably be expected to cause significant financial or reputational harm to the Company. The policy also authorizes the Company to require reimbursement of any profits the executive realizes on the sale of Company securities during the 12-month period following the issuance by the Company of a financial report that, due to the misconduct of the executive, is materially noncompliant with Federal securities laws. This policy applies to all senior executives of the Company, including all of the Named Executive Officers.

The Board of Directors continues to monitor regulatory developments relating to recoupment of incentive-based compensation and intends to further amend this policy, if necessary, to comply with any final regulations issued for the purpose of implementing the requirements of the Dodd-Frank Act.

Assessment of Risk Related to Compensation Programs

Following completion of a recent compensation risk assessment, the Company concluded that none of its compensation policies and practices is reasonably likely to have a material adverse effect on the Company. In connection with this assessment, the Company completed an inventory of its executive and non-executive compensation programs globally, with particular emphasis on incentive compensation plans or programs. The scope of the fiscal 2018 risk assessment generally was consistent with that of past years, except that we continued to respond to external market events by giving heightened attention to plan design, and whether the design, oversight, and controls in place have potential to create not only financial risk, but reputational risk as well. Based on this assessment, the Company evaluated the primary components of its compensation plans and practices to identify whether those components, either alone or in combination, properly balanced compensation opportunities and risk.

The Company believes that our overall cash versus equity pay mix, balance of shorter-term versus longer-term performance focus, balance of revenue versus profit focused performance measures, stock ownership guidelines, and “clawback” policy all work together to provide our employees and executives with incentives to deliver outstanding performance to build long-term stockholder value, while taking only necessary and prudent risks. In this regard, the Company’s strong ethics and its corporate compliance systems, which are overseen by the Audit Committee, further mitigate against excessive or inappropriate risk taking. In addition, our employee sales plans are designed under global guidelines, where oversight of plan terms, administration, and operation is stronger and governance roles are segregated.

The Compensation Committee, with assistance from its independent compensation consultant, George B. Paulin of FW Cook, reviewed a risk assessment that Mr. Paulin conducted for the Committee on the Company’s executive compensation policies and practices. Based on its consideration of these assessments, the Committee concurred with the Company’s determination that none of its compensation policies and practices is reasonably likely to have a material adverse effect on the Company.

	of the Securities and Exchange Commission, the change in Mr. Thulin’s pension value is shown as zero because the actuarial change in the present value of his pension benefits, calculated as described in the preceding sentence, decreased by $317,065. See Note 13 to the Company’s audited financial statements for the fiscal year ended December 31, 2018, included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission on February 7, 2019. There were no above-market earnings on deferred compensation under the Company’s nonqualified deferred compensation programs.
(5)	See the All Other Compensation table below for details of the amounts reported for 2018. The amounts reported in the All Other Compensation column for each fiscal year include Company matching contributions with respect to the deferred portion (if any) of each Named Executive Officer’s annual incentive payment earned for the year shown, even though the matching contribution was not actually made until after the end of such year. In our 2018 proxy statement, such Company matching contributions were reflected in the All Other Compensation column for the year in which the matching contribution was made. As a result, the amounts reported under All Other Compensation for 2016 and 2017 differ from the corresponding amounts reported in our 2018 proxy statement.
(6)	No amounts are reported for Ms. Bushman and Mr. Bauman for the years 2016 and 2017, or for Mr. Little for the year 2016, since they first became Named Executive Officers after those years.

(5)	This amount reflects the aggregate incremental cost to the Company for Mr. Roman’s and Mr. Thulin’s personal use of corporate aircraft during 2018. This aggregate incremental cost was calculated by combining the variable operating costs of such travel, including the cost of fuel, landing fees, parking fees, trip preparation fees, en route communication charges, en route navigation charges, on-board catering, and crew travel expenses. The Compensation Committee required each of Mr. Roman and Mr. Thulin to use the corporate aircraft for all business and personal travel during the portion of 2018 that he served as the Company’s Chief Executive Officer.
(6)	This amount reflects the expenses incurred by 3M during 2018 for home security equipment and monitoring services at the personal residence of Mr. Roman.

Abbreviations for the Type of Grant: 18PS = 2018 performance shares; Option = stock options; RSU = restricted stock unit; AIP = annual incentive pay.

(2)

The amounts shown as the Estimated Future Payouts Under Non-Equity Incentive Plan Awards reflect the target and maximum amounts that may be earned by each individual during 2018 under the Executive Annual Incentive Plan. This plan establishes a maximum amount of annual incentive compensation that may be earned by each covered executive during a plan year (established for purposes of complying with performance-based compensation exceptions of state tax laws that are similar to Section 162(m) of the Internal Revenue Code), which for each of the Named Executive Officers was one-quarter of one percent of the Company’s Adjusted Net Income for 2018, and then permits the Compensation Committee to pay each covered executive less than this maximum amount based on such factors as it deems relevant. Since the Executive Annual Incentive Plan was first adopted in 2007, the Compensation Committee has rarely used this discretion to pay a covered executive (other than our Chief Executive Officer) anything other than the same amount such executive would have received had he or she been participating in the Company’s broad-based Annual Incentive Plan. (For additional information, see “Annual Incentive” beginning on page 54 of this Proxy Statement).

(3)	The amounts shown as the Estimated Future Payouts Under Equity Incentive Plan Awards with respect to 2018 performance shares reflect the threshold, target, and maximum number of shares of 3M common stock (disregarding dividend equivalents) that may be earned by each individual as a result of the 2018 performance shares granted under the 2016 Long-Term Incentive Plan. The actual number of shares of 3M common stock to be delivered as a result of these performance shares will be determined by the performance of the Company during the three-year performance period of 2018, 2019, and 2020, as measured against four performance criteria selected by the Compensation Committee (Relative Organic Volume Growth, Return on Invested Capital, Earnings per Share Growth and Free Cash Flow Conversion). For more information on these performance criteria and the formulas for determining the number of shares of 3M common stock payable as a result of these performance shares, please refer to the “Long-Term Incentives — 2018 Annual Grants” and “Long-Term Incentives — Other Grants” beginning on pages 61 and 62 of this Proxy Statement, respectively.
(4)	The amounts shown as the All Other Option Awards reflect the number of shares of 3M common stock subject to nonqualified stock options granted to each individual during 2018 under the 2016 Long-Term Incentive Plan. The options granted on February 6, 2018, were part of the Company’s annual grant of stock options to the approximately 6,000 employees participating in the plan, and they vest in installments of one-third on each of the first three anniversaries of the grant date.
(5)	The exercise price for all stock options granted under the Company’s 2016 Long-Term Incentive Plan is set at the closing price at which 3M common stock traded on the NYSE on the option grant date.
(6)	The amounts in the Grant Date Fair Value of Stock and Option Awards column were determined in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 718, Compensation — Stock Compensation, excluding the effect of estimated forfeitures, and, in the case of performance share awards, are based upon the probable outcome of the applicable performance conditions at the time of grant. Assumptions made in the calculation of these amounts are included in Note 17 to the Company’s audited financial statements for the fiscal year ended December 31, 2018, included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission on February 7, 2019.

Pension Benefits

The following table shows the present value of the accumulated benefits payable to each of the Named Executive Officers, as well as the number of years of service credited to each individual, under each of the Company’s defined benefit pension plans determined using the same interest rate and mortality assumptions as those used for financial statement reporting purposes. See Note 13 to the Company’s audited financial statements for the fiscal year ended December 31, 2018, included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission on February 7, 2019.

A portion of Mr. Thulin’s benefits will actually be paid by a pension plan maintained by the Company’s subsidiary in Sweden (based on the years he was employed in Sweden before transferring to the United States), and the amount paid by this plan in Sweden will reduce the amount paid by the Employee Retirement Income Plan.

The Employee Retirement Income Plan (“ERIP”) is a tax-qualified defined benefit pension plan maintained by 3M for its eligible employees in the United States. Effective January 1, 2001, the Company amended the ERIP to include a pension equity formula for (1) employees hired or rehired on or after January 1, 2001, and (2) employees who voluntarily elected the pension equity formula during the one-time choice election period in 2001. The ERIP was closed to new participants effective January 1, 2009, meaning that employees hired or rehired on or after January 1, 2009, do not participate in the plan. Of the Named Executive Officers, Mr. Roman, Mr. Thulin, Mr. Gangestad, Mr. Shin, Ms. Bushman, and Mr. Bauman participate under the non-pension equity formula of the ERIP (the Portfolio I Plan), while Mr. Little participates under the pension equity formula of the ERIP (the Portfolio II Plan). Retirement benefits under the ERIP are based on an employee’s years of service and average annual earnings during the employee’s four highest-paid consecutive years of service. As applied to the Named Executive Officers, earnings for purposes of the ERIP include base salary and target annual incentive compensation. All benefits earned under the ERIP by the Named Executive Officers will be payable in the form of life annuities, unless an individual elects at the time their employment ends to receive the entire amount of his or her earned pension benefits in the form of a single lump-sum cash payment.

Under the Portfolio I Plan, employees earn annual benefits payable at retirement generally equal to 1.15 percent of their high-four average annual earnings multiplied by their years of service plus 0.35 percent of their high-four average annual earnings in excess of a Social Security breakpoint multiplied by their years of service (up to a maximum of 35 years). The Social Security breakpoint is an average of the Social Security taxable wage bases for each of the 35 years ending with the year each employee qualifies for receiving unreduced Social Security retirement benefits. Under the Portfolio I Plan, an employee may retire with an unreduced pension at age 60 (61 or 62 for employees born after 1942 and 1959, respectively). If the employee’s age and service at the time of retirement total at least 90 (91 or 92 for employees born after 1942 and 1959, respectively) the employee also would receive a Social Security bridge payment until age 62. Mr. Thulin is eligible to retire with unreduced retirement benefits. As of

Table of Contents

Executive compensation Executive compensation tables

March 13, 2019, each of Mr. Roman, Ms. Bushman and Mr. Bauman is eligible to retire with reduced early retirement benefits, with the reduction being equal to 5 percent of the pension otherwise payable for each year that such executive retires prior to age 61 (age 62 for Ms. Bushman).

Under the Portfolio II Plan, employees earn pension credits (from 3 percent to 12 percent) for each year of employment based on their age and accumulated years of service under the plan. Once their employment ends, these accumulated pension credits are multiplied by their high-four average annual earnings and added to an amount determined by multiplying one-half of these accumulated pension credits by their high-four average annual earnings in excess of a Social Security integration level (70 percent of the Social Security taxable wage base in the year employment ends). The sum of these two amounts is then converted into an annuity payable over the lifetime of the employee using fixed conversion factors. The Portfolio II Plan does not provide any subsidies for early retirement.

As a tax-qualified plan, the ERIP is subject to a variety of limits that apply to both the amount of any employee’s earnings that may be considered when determining the benefits earned under the plan as well as the maximum amount of benefits that any employee may earn. The Nonqualified Pension Plan is designed to provide additional benefits to employees, including the Named Executive Officers, affected by these limits. The amount of benefits earned under this Nonqualified Pension Plan generally equals the amount of benefits an employee was not able to earn under the ERIP as a result of the limits imposed by Federal tax laws. The benefits earned under this Nonqualified Pension Plan are generally paid in the form of a single lump-sum cash payment following the termination of their employment (subject to any applicable delay under Federal tax laws). Current employees were given a one-time opportunity during 2008 to elect to receive their benefits earned under this Nonqualified Pension Plan in the form of a life annuity following their retirement, and Mr. Shin elected to receive his benefits in the form of a life annuity.

Nonqualified Deferred Compensation

The following table reflects the participation during 2018 by the Named Executive Officers in three nonqualified deferred compensation plans offered by the Company. The Deferred Compensation Excess Plan allows eligible employees to defer for a number of years or until retirement from the Company the receipt of a portion of their base salary and annual incentive compensation. The Performance Awards Deferred Compensation Plan allows eligible employees to defer for a number of years or until retirement from the Company the payout of their performance share or performance unit awards under the 2008 Long-Term Incentive Plan and 2016 Long-Term Incentive Plan. The VIP Excess Plan allows eligible employees to defer until retirement from the Company the receipt of a portion of their base salary and annual incentive compensation. All three plans generally allow the eligible employees to elect to receive payment of their account balances in the form of either a single lump sum payment or in up to ten annual installments. With the exception of deferrals of performance shares under the Performance Awards Deferred Compensation Plan, earnings are credited to the amounts deferred under all three plans based on the returns paid on the investment funds available to participants in 3M’s qualified 401(k) plan or a fixed rate of return based on corporate bond yields (as selected by each participant). Earnings are credited to the deferrals of performance shares under the Performance Awards Deferred Compensation Plan based on the return on shares of 3M common stock, including reinvested dividends.

FOOTNOTES TO 2018 NONQUALIFIED DEFERRED COMPENSATION TABLE

(1)	With the exception of the amounts contributed by Mr. Roman, Mr. Thulin, Mr. Gangestad, and Mr. Bauman from the payout of their performance share awards for the 2015-2017 performance period and by Mr. Bauman from the payout of his annual incentive earned during 2017, all amounts contributed by these individuals during 2018 have been included in the Summary Compensation Table as Salary, Stock Awards, or Non-Equity Incentive Plan Compensation earned in 2016, 2017, or 2018. The Summary Compensation Table does not reflect any portion of the contributions from the payout of Mr. Roman’s, Mr. Thulin’s, Mr. Gangestad’s, and Mr. Bauman’s performance share awards for the 2015-2017 performance period because those awards were granted in 2015.
(2)	All amounts contributed by the Company on behalf of these individuals during 2018 are included in the “All Other Compensation” column of the Summary Compensation Table.
(3)	None of these amounts are included in the Summary Compensation Table as compensation earned in 2018, since none of the Company’s nonqualified deferred compensation plans provide above-market or preferential earnings.
(4)	Includes the following amounts that were reported as compensation for 2016 and 2017 in the Summary Compensation: Mr. Roman — $380,306; Mr. Thulin — $5,919,302; Mr. Gangestad — $357,419; Mr. Bauman — $0; Ms. Bushman — $0; Mr. Little — $1,748,007; and Mr. Shin — $290,843.

As reflected in the Compensation Discussion and Analysis portion of this Proxy Statement, 3M has no employment agreements with any of the Named Executive Officers nor does it have any severance or change in control plans or arrangements that would provide severance benefits to any of the Named Executive Officers in the event of the termination of their employment or a change in control of the Company. We also do not have any agreements that would provide automatic “single-trigger” accelerated vesting of equity compensation or excise tax gross-up payments to any of our Named Executive Officers in the event of a change in control of the Company. However, certain of the Company’s executive compensation and benefit plans provide all participants (including the Named Executive Officers) with certain rights or the right to receive payments in the event of the termination of their employment or upon a change in control of the Company. The terms applicable to these potential rights or payments in various situations are described below. Payments or benefits under other plans and arrangements that are generally provided on a non-discriminatory basis to all similarly situated employees of the Company upon the termination of their employment are not described, including (a) accrued base salary; (b) annual incentive earned with respect to completed performance periods; (c) retiree welfare benefits provided to substantially all of the Company’s U.S. employees, including retiree medical benefits; (d) distribution of vested account balances under the Company’s qualified 401(k) plan; (e) accrued pension benefits under the Company’s defined benefit pension plans payable following an employee’s retirement or other termination of employment (the amounts of these benefits earned by the Named Executive Officers are reported in the 2018 Pension Benefits Table); (f) life insurance benefits generally available to all salaried employees; and (g) distribution of account balances under the Company’s nonqualified deferred compensation plans (the account balances of the Named Executive Officers are reported in the 2018 Nonqualified Deferred Compensation Table).

Rights and Payments Upon Retirement

Following retirement (as described below), the Named Executive Officers are entitled to receive:

●	continued vesting of stock options previously granted under the Company’s stock plans, and the opportunity to exercise vested stock options previously granted under such plans during the remainder of the original term (up to 10 years) of such options;
●	for those Named Executive Officers initially appointed to a 3M executive position before January 1, 2006, or after December 31, 2017, payment for all previously granted performance shares upon completion of the respective three-year performance period (prorated to reflect the portion of the year worked only with respect to the performance shares granted in the year of retirement) and based on actual performance; and
●	for those Named Executive Officers initially appointed to a 3M executive position on or after January 1, 2006, and on or before December 31, 2017, payment for all previously granted performance shares upon completion of the respective three-year performance period (prorated to reflect the portion of the three-year performance period that occurred prior to the date of the Named Executive Officer’s retirement) and based on actual performance.

For this purpose, the term “Retirement” means a termination of employment with the Company after attaining age 55 with at least 10 years of service (age 55 with at least five years of service for awards granted before January 1, 2016).

Rights and Payments Upon Termination Due to Disability

In the event of the termination of their employment due to disability, the Named Executive Officers are entitled to receive:

●	continued vesting of stock options previously granted under the Company’s stock plans, and the opportunity to exercise vested stock options previously granted under such plans during the remainder of the original term (up to 10 years) of such options;
●	immediate vesting of all restricted stock units previously granted under the Company’s stock plans; and
●	payment for all previously granted performance shares upon completion of the respective three-year performance period, based on actual performance.

Rights and Payments Upon Termination Due to Death

In the event of the termination of their employment due to death, the Named Executive Officers are entitled to receive:

●	immediate vesting of all unvested stock options and restricted stock units previously granted under the Company’s stock plans, and the opportunity for the Named Executive Officer’s estate or beneficiaries to exercise all vested stock options during the two-year period following the date of death (but not beyond the original expiration date of any such stock option);
●	payment to the Named Executive Officer’s estate or beneficiaries, no later than March 15 of the year following the year in which the Named Executive Officer died, for all previously granted performance shares (in the same amount as paid for the performance shares granted to other Named Executive Officers if the date of death occurs after the end of the three-year performance period for such shares, and at the lesser of the target value or such other amount as determined by the Committee in its discretion if the date of death occurs before the end of the three-year performance period for such shares); and
●	payment to the Named Executive Officer’s beneficiaries of the proceeds from the life insurance policies provided for such Named Executive Officer pursuant to the Company’s Executive Life Insurance Plan.

Rights and Payments Upon Termination for Any Other Reason

In the event of the termination of their employment for any reason other than retirement, death, or disability (and other than in connection with a change in control, as described further below):

●	the Named Executive Officers will have the opportunity to exercise vested stock options granted under the Company’s stock plans within the first 90 days following the termination date (but not beyond the original expiration date of any such stock option), at which time any remaining vested stock options are forfeited; and
●	all unvested stock options, restricted stock units, and performance shares granted to the Named Executive Officers are forfeited immediately.

Rights and Payments Upon a Qualifying Termination in Connection with a Change in Control

If the Company terminates a Named Executive Officer’s employment for reasons other than Misconduct (or for awards granted prior to May 10, 2016, reasons other than Cause) or if a Named Executive Officer resigns for Good Reason, in any such case within 18 months following a “change in control event” of the Company (as defined for purposes of Section 409A of the Internal Revenue Code), all of the Named Executive Officer’s outstanding unvested stock options and restricted stock units granted under the Company’s stock plans will be immediately vested and all of such Named Executive Officer’s outstanding performance shares will be prorated and settled in accordance with the terms of the plan.

For purposes of our outstanding long-term incentive awards, the terms “Misconduct”, “Cause”, and “Good Reason” mean the following:

“Misconduct” means (i) the Named Executive Officer’s willful failure to substantially perform his or her duties (other than a failure resulting from his or her disability); (ii) the Named Executive Officer’s willful failure to carry out, or comply with any lawful and reasonable directive of the Board or his or her immediate supervisor; (iii) the occurrence of any act or omission by the Named Executive Officer that could reasonably be expected to result in (or has resulted in) his or her conviction, plea of no contest, plea of nolo contendere, or imposition of unadjudicated probation for any felony or indictable offense or crime involving moral turpitude; (iv) the Named Executive Officer’s commission of an act of fraud, embezzlement, misappropriation, misconduct, or breach of fiduciary duty against the Company or any of its subsidiaries or affiliates or any of their officers, directors, employees, customers, suppliers, insurers or agents; (v) the Named Executive Officer’s material breach of any material provision of any written agreement with the Company or any subsidiary; or (vi) any other intentional misconduct by the Named Executive Officer that significantly affects the business or affairs of the Company or any subsidiary in an adverse manner.

“Cause” means a material violation of any policy of the Company, or embezzlement or theft of property belonging to the Company.

“Good Reason” means (i) a material diminution in the Named Executive Officer’s position, authority, duties, or responsibilities as in effect immediately prior to the change in control; (ii) a material diminution in the Named Executive Officer’s base salary or annual planned cash compensation; or (iii) a material change in the geographic location at which the Named Executive Officer is required to perform services for the Company.

Executive compensation Pay ratio

FOOTNOTES TO 2018 POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL TABLE

Pay ratio

Presented below is the ratio of annual total compensation of our CEO to the annual total compensation of our median employee (excluding our CEO) for 2018. The ratio reflects a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K under the Securities Exchange Act of 1934.

In determining the ratio below, we began by using the same median employee (a full-time production employee in the Midwestern United States) identified for purposes of calculating the ratio included in our 2018 proxy statement because there have not been changes in our employee population or employee compensation arrangements that we believe would significantly impact the pay ratio disclosure. The median employee initially was identified based on target annual total cash compensation for each employee as of December 31, 2017. For these purposes, annual total cash compensation included base salary or hourly wages, cash incentives, commissions and comparable cash elements of compensation in non-U.S. jurisdictions and was calculated using internal human resources records. All amounts were annualized for permanent employees who did not work for the entire year, such as new hires, employees on paid or unpaid leave of absence and employees called for active military duty. We did not apply any cost-of-living adjustments as part of the calculation.

The median employee was selected from among 90,823 full-time, part-time, temporary and seasonal workers who were employed as of December 31, 2017. As permitted by Item 402(u) of Regulation S-K, we excluded 1,575 employees (including 966 non-U.S. employees) who joined the Company during 2017 as part of our acquisition of Scott Safety when making this determination. Except for the employees excluded on the basis of the Scott Safety acquisition completed in 2017, we did not exclude any other employees (whether pursuant to the de minimis exemption for foreign employees or any other permitted exclusion).

As a result of our CEO transition in 2018, and as permitted by Item 402(u) of Regulation S-K, our CEO annual total compensation for purposes of this disclosure was calculated by combining the total compensation for each of Mr. Roman and Mr. Thulin for the periods of 2018 in which they served as CEO, respectively. The 2018 annual total CEO compensation calculated on this basis was $17,320,459. The 2018 annual total compensation for our median employee was $57,313. Among other things, these amounts include base salary, overtime, incentive payments, stock-based compensation (based on the grant date fair value of awards granted during 2018), changes in pension values and retirement plan contributions. As calculated in this manner, the ratio of our CEOs’ total combined compensation to our median employee’s total compensation for fiscal year 2018 is 302 to 1. Because the annual CEO compensation used in calculating this ratio includes the combined compensation of two individuals who served as CEO in 2018, the Company’s pay ratio for 2018 may not be comparable to its pay ratio in other years. For this and other reasons, the Company's pay ratio also may not be comparable to the pay ratios of other companies.

Stockholder proposal

PROPOSAL	Stockholder Proposal on Setting Target Amounts for CEO Compensation
	●Stockholder proposal on setting target amounts for CEO compensation, if properly presented at the meeting. ●See the Board’s opposition statement.

3M has received a stockholder proposal from the United Steelworkers, Paper and Forestry, Rubber, Manufacturing, Energy, Allied Industrial and Service Workers International Union, 60 Boulevard of the Allies, Pittsburgh, PA 15222, the owner of 68 shares of 3M common stock (the “Proponent”). The Proponent has requested that the Company include the following proposal and supporting statement (in italics) in its proxy statement for the Annual Meeting of Stockholders. The proposal may be voted on at the Annual Meeting only if properly presented by the Proponent or the Proponent’s qualified representative. For the reasons set forth following the Proponent’s statement, your Board of Directors recommends that you vote “AGAINST” this proposal.

RESOLVED: Shareholders of 3M Corporation (the “Company’’) request that the Compensation Committee of the Board of Directors take into consideration the pay grades and/or salary ranges of all classifications of Company employees when setting target amounts for CEO compensation. The Compensation Committee should describe in the Company’s proxy statements for annual shareholder meetings how it complies with this requested policy. Compliance with this policy is excused if it will result in the violation of any existing contractual obligation or the terms of any existing compensation plan.

Supporting Statement

Like at many companies, our Company’s Compensation Committee uses peer group benchmarks of what other companies pay their CEOs to set its target CEO compensation. These target pay amounts are then subject to performance adjustments. To ensure that our Company’s CEO compensation is reasonable relative to our Company’s overall employee pay philosophy and structure, we believe that the Compensation Committee should also consider the pay grades and/or salary ranges of Company employees when setting CEO compensation target amounts.

This proposal does not require the Compensation Committee to use other employee pay data in a specific way to set CEO compensation targets. Under this proposal, the Compensation Committee will have discretion to determine how other employee pay should impact CEO compensation targets. The Compensation Committee also will retain authority to use peer group benchmarks and/or any other metric to set CEO compensation target amounts. Over time, using peer group benchmarks to set CEO compensation can lead to pay inflation. Although many companies target CEO compensation at the median of their peer group, certain companies have targeted their CEO’s pay above median. In addition, peer groups can be cherry-picked to include larger or more successful companies where CEO compensation is higher. (Charles Elson and Craig Ferrere, “Executive Superstars, Peer Groups and Overcompensation,” Journal of Corporation Law, Spring 2013).

High pay disparities between CEOs and other senior executives may undermine collaboration and teamwork. According to Institutional Shareholder Services, an excessive pay disparity between the CEO and the next highest-paid named executive officer is a problematic pay practice that may result in a recommendation to its clients that they vote against advisory votes on executive compensation (Institutional Shareholder Services, United States Proxy Voting Manual, February 23, 2016, p. 147). In our view, the pay of non-executive employees should also be considered. High CEO compensation can impact the morale and productivity of employees who are not senior executives. According to a Glassdoor study of employee opinions, “Higher CEO compensation is statistically linked to lower CEO approval ratings on average” (Glassdoor, What Makes a Great CEO?, August 2016, available at https://www.glassdoor.com/research/studies/what-makes-a-great-ceo/).

For those reasons, we urge you to vote in favor of this proposal.

Stockholder proposal Proposal 4

Board’s Statement Opposing the Proposal

After careful consideration, and for the reasons set forth below, the Board believes that it is not in the best interests of 3M or its stockholders to approve the proposed resolution, for the following reasons:

1.	The Company already maintains global compensation principles that are intended to ensure that its compensation practices are fair and reasonable as applied to both executive and non-executive employees. These principles align with the Company’s vision and strategies, balance both individual and enterprise-wide performance and seek to provide competitive wages and benefits with consistent positioning in the median range of the most-relevant markets to employees based on roles, responsibilities, skills and performance. To monitor and support the effectiveness of this program, the Company also periodically compares its pay components to those of other premier companies, and adjusts them as necessary to stay competitive and attract, retain and motivate a highly qualified, diverse workforce at all levels throughout the organization, not just for its executives.
2.	The Board of Directors believes that the overwhelming majority of our stockholders support the Company’s current executive compensation program. As described in more detail in the Compensation Discussion and Analysis portion of this Proxy Statement, the current program emphasizes a strong pay-for-performance philosophy and seeks to align the compensation of the Company’s Chief Executive Officer and other executive officers with the interests of long-term 3M stockholders. In 2018, approximately 93 percent of the votes cast on the Company’s say-on-pay proposal approved the compensation of the Named Executive Officers as disclosed in last year’s Proxy Statement.
3.	The Compensation Committee already reviews and considers the ratio of annual total compensation of our Chief Executive Officer to the annual total compensation of our median employee (excluding our Chief Executive Officer), as reported in the proxy statement, which the Company believes provides a similar perspective to the Compensation Committee at no incremental cost to the Company. 3M has operations and different compensation programs in more than 70 countries around the world. Compliance with the proposal would require substantial coordination with local employees in foreign countries to collect and transmit the necessary data on “all classifications” of the Company’s approximately 94,000 employees worldwide, all of which would need to be carefully analyzed and summarized. The Company believes that the time, cost and resource burden associated with implementing the proposal is not warranted by any incremental benefit that the resulting information may be able to offer.

RECOMMENDATION OF THE BOARD

The Board of Directors unanimously recommends a vote  “AGAINST”  this proposal. Proxies solicited by the Board of Directors will be voted  “AGAINST”  this proposal unless a stockholder indicates otherwise in voting the proxy.

Section 16(a) beneficial ownership reporting compliance

Section 16(a) of the Securities Exchange Act of 1934 requires our directors and executive officers, and any person owning more than 10 percent of the outstanding shares of 3M common stock, to file with the Securities and Exchange Commission reports regarding their ownership and changes in their ownership of our stock. As a practical matter, 3M assists its directors and executive officers by monitoring transactions and completing and filing Section 16 reports on their behalf. 3M believes that during 2018, its directors and executive officers timely filed all required Section 16(a) reports, except that a Form 4 reporting the issuance of 327 shares of stock to Dr. Dambisa Moyo as compensation for serving on the 3M Board of Directors was inadvertently filed late due to an administrative oversight. In making this statement, 3M has relied upon examination of copies of Forms 3, 4, and 5 and the written representations of its directors and executive officers.

Information About the Notice of Internet Availability of Proxy Materials

Why did I receive a Notice of Internet Availability of the proxy materials and not the printed proxy materials?

The Securities and Exchange Commission allows companies to furnish their proxy materials to stockholders over the Internet. As a result, we are mailing to many of our stockholders a Notice of Internet Availability of Proxy Materials instead of a paper copy of the proxy materials. In addition, we are providing the notice and proxy materials by e-mail to some of our stockholders who previously consented to electronic delivery of proxy materials. Those stockholders should have received an e-mail containing a link to the website where the proxy materials are available, as well as a link to the proxy voting website. All stockholders receiving the Notice of Internet Availability of Proxy Materials will have the ability to access the proxy materials over the Internet and to request to receive a paper copy of the proxy materials by mail. Instructions on how to access the proxy materials over the Internet or to request a paper copy may be found in the notice. In addition, the notice contains instructions on how you may request to receive proxy materials in printed form by mail or to access them electronically in connection with future distributions of proxy materials. Distributing proxy materials electronically conserves natural resources and reduces the costs of printing and distributing our proxy materials.

Why did I receive a printed copy of the proxy materials and not the Notice of Internet Availability of Proxy Materials?

We are providing some of our stockholders, including stockholders who have previously requested to receive paper copies of the proxy materials, with paper copies of the proxy materials instead of the Notice of Internet Availability of Proxy Materials.

How do I view the proxy materials online?

Go to www.proxyvote.com and follow the instructions to view the materials. You will need to provide the control number printed in the box marked by the arrow located on your Notice of Internet Availability of Proxy Materials (see example below — the information in the box is an example only — your number will be different and is unique to you).

What if I prefer to receive a paper copy of the proxy materials?

You can easily request a paper copy of the proxy materials (including the Notice of Annual Meeting, Proxy Statement, and 2018 Annual Report) at no cost by using one of the three methods below. You will need to provide the control number printed in the box marked by the arrow located on your Notice of Internet Availability of Proxy Materials (see example above — the information in the box is an example only — your number will be different and is unique to you).

Can I request to receive my Notice of Internet Availability of Proxy Materials by e-mail rather than by mail?

You may request to receive proxy materials for future meetings by e-mail via www.proxyvote.com or www.investordelivery.com and follow the electronic delivery enrollment instructions. If you choose to access future proxy materials electronically, you will receive an e-mail with instructions containing a link to the website where those materials are available and a link to the proxy voting website. Your election to access proxy materials by e-mail will remain in effect until you terminate it.

Please note that you MAY NOT USE your Notice of Internet Availability of Proxy Materials to vote your shares; it is NOT a form for voting. If you return the Notice of Internet Availability of Proxy Materials in an attempt to vote your shares, that vote will not count. For more information about the Notice of Internet Availability of Proxy Materials, please visit: www.sec.gov/spotlight/ proxymatters/e-proxy.shtml

Stockholders Entitled to Vote

Each share of our common stock outstanding as of the close of business on March 19, 2019, the record date, is entitled to one vote at the Annual Meeting on each matter properly brought before the meeting. As of that date, there were 575,896,636 shares of common stock issued and outstanding.

Most 3M stockholders hold their shares through a broker, bank, trustee, or other nominee (which for simplicity we refer to as a “broker or other nominee”) rather than directly in their own name. As summarized below, there are some distinctions between shares held of record and those owned beneficially:

Stockholder of Record		If your shares are registered directly in your name with 3M’s transfer agent, EQ Shareowner Services, you are considered the stockholder of record of those shares and the Notice of Internet Availability of Proxy Materials, or if you requested paper delivery, a copy of these proxy materials are being sent directly to you by 3M. As the stockholder of record, you have the right to grant your voting proxy directly to 3M or to vote in person at the meeting. You may also vote on the Internet or by telephone, as described in the Notice of Internet Availability of Proxy Materials and below under the heading “Voting Methods.”
Beneficial Owner		If your shares are held by a broker or other nominee, you are considered the beneficial owner of shares held in street name and these proxy materials are being forwarded to you by your broker or other nominee who is considered the stockholder of record of those shares. As the beneficial owner, you have the right to direct your broker or other nominee on how to vote and are also invited to attend the meeting. However, since you are not the stockholder of record, you may not vote these shares in person at the meeting, unless you obtain a legal proxy from the broker or other nominee. Your broker or other nominee is obligated to provide you with a voting instruction card for you to use. You may also vote on the Internet or by telephone, as described in the Notice of Internet Availability of Proxy Materials and below under the heading “Voting Methods.” If you fail to provide voting instructions to your broker or other nominee, it will have discretion to vote your shares with respect to Proposal 2, but not with respect to Proposals 1, 3, or 4, as described below under “Voting Requirements to Elect Directors and Approve Each of the Proposals Described in this Proxy Statement.”
Plan Accounts		If your shares are held in your account in the 3M Voluntary Investment Plan and Employee Stock Ownership Plan or the 3M Savings Plan, you are considered the beneficial owner of these shares and the trustee of the plans is considered the stockholder of record. Participants in 3M’s Voluntary Investment Plan and Employee Stock Ownership Plan or the 3M Savings Plan may direct the trustee on how to vote the shares allocated to their account via the Internet, by telephone, or by signing and submitting the proxy card as described in the Notice of Internet Availability of Proxy Materials and below under the heading “Voting Methods.” Participants in 3M’s Voluntary Investment Plan and Employee Stock Ownership Plan or the 3M Savings Plan may also direct the trustee how to vote a proportionate number of allocated shares of common stock for which it has not received direction by following the same voting instructions. If you fail to direct the trustee how to vote your shares by following these instructions, the trustee will vote your shares as described in the proxy card.

Proposals you are Asked to Vote on and the Board’s Voting Recommendations

The following proposals are included in this Proxy Statement and are scheduled to be voted on at the meeting. 3M’s Board recommends that you vote your shares as indicated below. 

Proposals:			The Board’s Voting Recommendations:		Rationale for Support:		For Further Details:
1.	Elect the twelve directors identified in this Proxy Statement, each for a term of one year.		“FOR”  each nominee to the Board		Our nominees are distinguished leaders who bring a mix of skills and qualifications to the Board and can represent the interests of all stockholders.		Page 6
2.	Ratify the appointment of PricewaterhouseCoopers LLP as 3M’s independent registered public accounting firm for 2019.		“FOR”		Based on its assessment of the qualifications and performance of PricewaterhouseCoopers LLP (“PwC”), the Audit Committee believes that it is in the best interests of the Company and its stockholders to retain PwC.		Page 42
3.	Approve, on an advisory basis, the compensation of our named executive officers.		“FOR”		Our executive compensation program appropriately aligns our executives’ compensation with the performance of the Company and its business units as well as their individual performance.		Page 46
4.	Stockholder proposal on setting target amounts for CEO compensation, if properly presented at the meeting.		“AGAINST”		See the Board’s opposition statement.		Page 83

Other than the proposals described in this Proxy Statement, the Board is not aware of any other matters to be presented for a vote at the Annual Meeting. If you grant a proxy by telephone, Internet, or by signing and returning your proxy card, any of the persons appointed by the Board as proxy holders — Nicholas C. Gangestad, Gregg M. Larson, and Inge G. Thulin — will have the discretion to vote your shares on any additional matters properly presented for a vote at the meeting. If any of our nominees is unavailable as a candidate for director, the above-named proxy holders will vote your proxy for another candidate or candidates as may be nominated by the Board of Directors.

Voting Requirements to Elect Directors and Approve Each of the Proposals Described in This Proxy Statement

Quorum		The presence of the holders of a majority of the outstanding shares of common stock entitled to vote at the Annual Meeting, present in person or represented by proxy, is necessary to constitute a quorum. Abstentions and “broker non-votes” are counted as present for purposes of determining a quorum. As discussed below, a “broker non-vote” occurs when a broker or other nominee holding shares for a beneficial owner does not vote on a particular proposal because the broker or other nominee does not have discretionary voting power for that proposal and has not received instructions from the beneficial owner.
Broker Voting		Under NYSE rules, brokers have discretionary authority to vote their clients’ shares in “routine” matters (including Proposal 2, the ratification of PwC as our independent registered public accounting firm) so long as the beneficial owner of those shares did not provide voting instructions to the broker at least ten days before the stockholder meeting. Director elections, stockholder proposals, and the say-on-pay proposal, are not considered “routine” matters for these purposes. As a result, if you do not provide your broker with instructions as to how to vote your shares, your broker will be prohibited from voting on Proposals 1, 3, and 4, resulting in a “broker non-vote” with respect to those proposals. If you are a beneficial owner (other than as a participant in the 3M Voluntary Investment Plan and Employee Stock Ownership Plan or the 3M Savings Plan), your broker or other nominee is permitted to vote your shares on the ratification of PricewaterhouseCoopers LLP as our independent registered public accounting firm for 2019, even if it does not receive voting instructions from you.

Other information Proxy statement

Election of Directors		In accordance with 3M’s Bylaws, each director is elected by the vote of the majority of votes cast (which means the number of votes cast “for” a director’s election exceeds the number of votes cast “against” that director’s election, with “abstentions” and “broker non-votes” not counted as a vote cast either “for” or “against” that director’s election) with respect to that director’s election at this meeting for the election of directors at which a quorum is present. The Nominating and Governance Committee has established procedures under which any incumbent director who is not elected shall offer to tender his or her resignation to the Board. In the event an incumbent director fails to receive a majority of the votes cast in the election, the Nominating and Governance Committee, or such other committee designated by the Board of Directors, shall make a recommendation to the Board of Directors as to whether to accept or reject the resignation of such incumbent director, or whether other action should be taken. The Board of Directors shall act on the resignation, taking into account the Committee’s recommendation, and publicly disclose (by issuing a press release and filing appropriate disclosure with the Securities and Exchange Commission) its decision regarding the resignation and, if such resignation is rejected, the rationale behind the decision within ninety (90) days following certification of the election results. The Nominating and Governance Committee in making its recommendation and the Board of Directors in making its decision each may consider any factors and other information that they consider appropriate and relevant. An incumbent director who fails to receive a majority of the votes cast in the election and who tenders his or her resignation pursuant to the procedures described above shall remain active and engaged in Board activities while the Nominating and Governance Committee and the Board decide whether to accept or reject such resignation, or whether other action should be taken. However, it is expected that such incumbent director shall not participate in any proceedings by the Nominating and Governance Committee or the Board regarding whether to accept or reject such director’s resignation, or whether to take other action with respect to such director. If the Board of Directors accepts a director’s resignation, or if a nominee for director is not elected and the nominee is not an incumbent director, then the Board of Directors may fill the resulting vacancy pursuant to the Bylaws.
All Other Proposals		The affirmative “FOR” vote of a majority of those shares present in person or represented by proxy at the meeting and entitled to vote on the matter is required to approve Proposals 2, 3, and 4. In tabulating the voting result for any particular proposal “broker non-votes” (if applicable) are not counted as votes “FOR” or “AGAINST” the proposal. An abstention will, however, be counted as entitled to vote on a proposal and will, therefore, have the effect of a vote “AGAINST.”

Voting Methods

If you hold shares directly as the stockholder of record, you may vote by granting a proxy or by voting in person at the Annual Meeting by requesting a ballot. If you hold shares beneficially in street name, you may vote by submitting voting instructions to your broker or other nominee or in person at the Annual Meeting by requesting a legal proxy from your broker or other nominee. If you own shares beneficially as a participant in the 3M Voluntary Investment Plan and Employee Stock Ownership Plan or the 3M Savings Plan, you may vote by submitting voting instructions to the trustee. In most instances, you will be able to do this over the Internet, by telephone, or by mail. Even if you plan to attend the Annual Meeting, we recommend that you vote your shares in advance as described below so that your vote will be counted if you later decide not to attend the Annual Meeting.

Please refer to the summary instructions below and those included on your Notice of Internet Availability of Proxy Materials or proxy card or, for shares held in street name, the voting instruction card provided by your broker or other nominee.

Counting the Vote

In the election of directors, you may vote “FOR” or “AGAINST” one or more of the nominees or you may “ABSTAIN.” Abstentions will have no effect on the outcome of the election of directors. For Proposals 2, 3, and 4, you may vote “FOR,” “AGAINST,” or “ABSTAIN,” but please note that abstentions will have the same effect as a vote “AGAINST.” If you sign your proxy card or broker voting instruction card but provide no voting instructions, your shares will be voted in accordance with the recommendations of the Board. Shares held in your account in the 3M Voluntary Investment Plan and Employee Stock Ownership Plan or the 3M Savings Plan will be voted by the trustee as described in “Stockholders Entitled to Vote” beginning on page 90.

Representatives of Broadridge Financial Solutions, Inc. will tabulate the votes and act as the inspectors of election.

Confidentiality

The Company’s Board of Directors has a policy that all stockholder proxies, ballots, and tabulations that identify stockholders are to be maintained in confidence. No such document will be available for examination, and the identity and vote of any stockholder will not be disclosed, except as necessary to meet legal requirements and allow the inspectors of election to certify the results of the stockholder vote. The policy also provides that inspectors of election for stockholder votes must be independent and cannot be employees of the Company. Occasionally, stockholders provide written comments on their proxy card that may be forwarded to 3M management.

Results of the Vote

We will issue a press release announcing the preliminary voting results for items of business properly presented at the meeting and will disclose the results for those items in a Current Report on Form 8-K filed with the Securities and Exchange Commission within four business days of the Annual Meeting date. The press release with voting results will also be available on our website at www.3M.com/profile/pressbox/index.jhtml.

Delivery of Documents to Stockholders Sharing an Address

Securities and Exchange Commission rules allow us to deliver a single copy of an annual report and proxy statement to any household not participating in electronic proxy material delivery at which two or more stockholders reside, if we believe the stockholders are members of the same family (a practice called “householding”). We believe that householding benefits both you and the Company by eliminating duplicate mailings to stockholders living at the same address and by reducing our printing and mailing costs. Each stockholder will continue to receive a separate proxy card or voting instruction card.

Your household may have received a single set of proxy materials this year. If you prefer to receive your own copy now or in future years, please request a duplicate set by calling 1-800-579-1639, by going to www.proxyvote.com, by e-mailing sendmaterial@proxyvote.com, or by writing to 3M Company, c/o Broadridge, 51 Mercedes Way, Edgewood, NY 11717. Alternatively, if your household received multiple sets of proxy materials this year, and members of your household who are entitled to receive proxy materials would all prefer to receive only a single set of proxy materials, you may submit such a request as specified in the preceding sentence.

If a broker or other nominee holds your shares, you may continue to receive some duplicate mailings. Certain brokers will eliminate duplicate account mailings by allowing stockholders to consent to such elimination, or through implied consent if a stockholder does not request continuation of duplicate mailings. Since not all brokers and nominees may offer stockholders the opportunity this year to eliminate duplicate mailings, you may need to contact your broker or other nominee directly to discontinue duplicate mailings to your household.

List of Stockholders

A list of the stockholders of record entitled to vote at the Annual Meeting will be available for inspection at the Annual Meeting for any purpose germane to the meeting. The list also will be available for ten days prior to the meeting between the hours of 7:45 a.m. and 4:30 p.m., Eastern Daylight Time, at Aearo Technologies, 7911 Zionsville Road, Indianapolis, Indiana 46268, by contacting the Secretary of the Company.

Cost of Proxy Solicitation

3M will pay for the cost of preparing, assembling, printing, mailing, and distributing these proxy materials.

We have hired Georgeson Shareholder Communications, Inc. to assist us in the distribution of proxy materials and the solicitation of votes. We will pay Georgeson Shareholder Communications, Inc. a fee of $20,000 plus expenses for these services. We will also reimburse brokerage houses and other custodians, nominees, and fiduciaries for their reasonable out-of-pocket expenses for forwarding proxy and solicitation materials to beneficial owners of stock.

Transfer Agent

Requirements for submission of stockholder proposals for next year’s Annual Meeting

In order for a stockholder proposal to be considered for inclusion in 3M’s Proxy Statement for next year’s Annual Meeting, our Corporate Secretary must receive the proposal by November 28, 2019. Such proposals must be sent via registered, certified, or express mail (or other means that allows the stockholder to determine when the proposal was received by the Company) to: Gregg M. Larson, Vice President, Deputy General Counsel and Secretary, 3M Company, 3M Center, Building 220-13E-26A, St. Paul, MN 55144-1000. Such proposals must comply with the Securities and Exchange Commission’s regulations regarding the inclusion of stockholder proposals in Company sponsored proxy materials, such as the stockholder continuing to own a minimum number of shares until the Annual Meeting and appearing in person or through an authorized representative at the meeting to present the proposal.

Alternatively, stockholders intending to present a proposal at next year’s Annual Meeting without having it included in the Company’s Proxy Statement must comply with the requirements set forth in the Company’s Bylaws, a copy of which is available at www.3M.com under Investor Relations — Governance. Our Bylaws require, among other things, that our Corporate Secretary receive written notice from the stockholder no earlier than the close of business on November 28, 2019, and no later than the close of business on December 28, 2019. The notice must contain the information required by our Bylaws.

Proposals received by the Corporate Secretary after the dates mentioned will not be included in the Proxy Statement or acted upon at next year’s Annual Meeting.

By Order of the Board of Directors.

Appendix A - supplemental consolidated statement of income information

Reconciliation of GAAP to non-GAAP financial measures
(millions, except per-share amounts) (unaudited)

In addition to reporting financial results in accordance with U.S. generally accepted accounting principles (GAAP), the Company also discusses non-GAAP measures that exclude special items. Operating income, net income attributable to 3M (hereafter referred to as “net income”), and diluted earnings per share attributable to 3M common stockholders (hereafter referred to as “diluted earnings per share”) are all measures for which 3M provides the reported GAAP measure and an adjusted measure (excluding special items). Special items are not in accordance with, nor are they a substitute for, GAAP measures. Special items represent significant charges or credits that are important to an understanding of the Company’s ongoing operations. The Company uses these non-GAAP measures to evaluate and manage the Company’s operations. The Company believes that discussion of results excluding special items is meaningful to investors as it provides a useful analysis of ongoing operating trends. The determination of special items may not be comparable to similarly titled measures used by other companies.

The reconciliations provided below reconcile the non-GAAP financial measures with the most directly comparable GAAP financial measures for the twelve months ended December 31, 2018 and 2017:

(a)	In February 2018, 3M reached an agreement with the State of Minnesota that resolved the previously disclosed Natural Resource Damages (NRD) lawsuit filed by the State against the Company related to certain PFCs present in the environment. Under the terms of the settlement, 3M agreed to provide an $850 million grant to the State for a special “3M Water Quality and Sustainability Fund.” This Fund will enable projects that support water sustainability in the Twin Cities East Metro region, such as continued delivery of water to residents and enhancing groundwater recharge to support sustainable growth. The projects will also result in habitat and recreation improvements, such as fishing piers, trails, and open space preservation. 3M recorded a charge of $897 million ($770 million after-tax), inclusive of legal fees and other related obligations, in the first quarter of 2018 associated with the resolution of this matter. In the fourth quarter of 2018, 3M recorded a related $60 million tax expense resulting from the Company’s ongoing IRS examination under the Compliance Assurance Process (CAP) and new guidance released under the Tax Cuts and Jobs Act.
(b)	During the first quarter of 2018, 3M recorded a tax expense of $217 million related to a measurement period adjustment to the provisional amounts recorded in December 2017 from the enactment of the Tax Cuts and Jobs Act (TCJA). In the fourth quarter 2018, 3M finalized the tax impact related to TCJA with a reversal of previously recorded tax expense in the amount of $41 million.
(c)	In June 2018, 3M completed the sale of substantially all of its Communication Markets Division and reflected a pre-tax gain of $494 million as a result of this divestiture. Additionally, in December 2018, completed the sale of the remaining telecommunications system integration services portion of the business based in Germany and reflected a pre-tax gain of $15 million as a result of this divestiture. Both divestitures were reported within the Company’s Electronics and Energy business. During the second quarter and fourth quarter of 2018, management approved and committed to undertake certain restructuring actions related to addressing corporate functional costs following the Communication Markets Division divestiture. These actions resulted in a second quarter 2018 pre-tax charge of $105 million and a fourth quarter 2018 pre-tax charge of $22 million, net of adjustments for reductions in cost estimates.
(d)	During the fourth quarter of 2017, 3M recorded a net tax expense of $762 million related to the enactment of the Tax Cuts and Jobs Act (the “TCJA”). The expense is primarily related to the TCJA’s transition tax on previously unremitted earnings of non-U.S. subsidiaries and was net of remeasurement of 3M’s deferred tax assets and liabilities considering the TCJA’s newly enacted tax rates and certain other impacts. This provisional amount was subject to adjustment during the measurement period of up to one year following the December 2017 enactment of the TCJA, as provided by recent SEC guidance. In addition to reporting financial results in accordance with GAAP, the Company also provides non-GAAP measures that adjust for the net impact of enactment of the TCJA. This item represents a significant charge that impacted the Company’s financial results. Income, earnings per share, and the effective tax rate are all measures for which 3M provides the reported GAAP measure and an adjusted measure. The adjusted measures are not in accordance with, nor are they a substitute for, GAAP measures. Because of the TCJA, the Company made a $600 million pension contribution to its U.S. defined benefit pension plan. This contribution did not impact 2017 net income, but it did impact Free Cash Flow Conversion and ROIC. The Company considers these non-GAAP measures in evaluating and managing the Company’s operations. The Company believes that discussion of results adjusted for this item is meaningful to investors as it provides a useful analysis of ongoing underlying operating trends.

Appendix A Reconciliation of GAAP to non-GAAP financial measures

(e)

Free cash flow and free cash flow conversion are not defined under GAAP. Therefore, they should not be considered a substitute for income or cash flow data prepared in accordance with GAAP and may not be comparable to similarly titled measures used by other companies. The Company defines free cash flow as net cash provided by operating activities less purchases of property, plant and equipment. It should not be inferred that the entire free cash flow amount is available for discretionary expenditures. The Company defines free cash flow conversion as free cash flow divided by net income attributable to 3M. The Company believes free cash flow and free cash flow conversion is meaningful to investors as they are useful measures of performance and the Company uses these measures as an indication of the strength of the Company and its ability to generate cash. In 2017, net cash provided by operating activities was impacted by 3M’s enactment of the TCJA, along with a U.S. pension contribution of $600 million that 3M made following the signing of tax reform. On a combined basis, these items benefited free cash flow conversion by three percentage points. Refer to the proceeding “Cash Flows from Operating Activities” section for discussion of additional items that impacted operating cash flow. Refer to the proceeding “Cash Flows from Investing Activities” section for discussion on capital spending for property, plant and equipment.

(f)

Return on Invested Capital (ROIC) is not defined under U.S. generally accepted accounting principles. Therefore, ROIC should not be considered a substitute for other measures prepared in accordance with GAAP and may not be comparable to similarly titled measures used by other companies. The Company defines ROIC as adjusted net income (net income including non-controlling interest plus after-tax interest expense) divided by average invested capital (equity plus debt). The Company believes ROIC is meaningful to investors as it focuses on shareholder value creation.
