Proposal III Ratification of the Company’s Independent Registered Public Accounting Firm for the Year Ending December 31, 2014

This proxy statement and the accompanying form of proxy are being furnished to the stockholders of Axiall Corporation (the “Company”) on or about April 18, 2014 in connection with the solicitation of proxies by our Board for use at the annual meeting of stockholders

to be held on May 20, 2014 at 1:30 p.m. local time at the JW Marriott Hotel, 3300 Lenox Road NE, Atlanta, Georgia 30326, and any adjournment or postponement of the annual meeting.

The enclosed proxy card provides voting instructions for eligible stockholders. Stockholders not wishing to vote by telephone or via the Internet or whose proxy card does not mention information about telephone or Internet voting should complete the enclosed paper proxy card and return it in the enclosed postage-paid envelope. Signing and returning the proxy card or submitting the proxy by telephone or via the Internet does not affect your right to revoke your proxy or to vote in person at the annual meeting.

If your shares are held in “street name” by a bank, broker or other nominee, you should check the voting form used by that firm to determine whether you may provide voting instructions to the bank, broker or other nominee by telephone or the Internet.

• FOR the election of the ten nominees as directors;

• FOR the approval, on an advisory basis, of the compensation of the Company’s executive officers; and

• FOR the ratification of the appointment of E&Y to serve as our independent registered public accounting firm for the year ending December 31, 2014.

Our Board does not know of any other business to be brought before the annual meeting, but if any other business is properly brought before the annual meeting, proxies will be voted upon those matters in accordance with the judgment of the person or persons acting under the proxies.

We will pay the cost of soliciting proxies. In addition to use of the mails, proxies may be solicited in person or by telephone or facsimile by our directors and officers, who will not receive additional compensation for these services. We have retained AST Phoenix Advisors to assist in the solicitation of proxies for a fee

of $8,000. Brokerage houses, nominees, custodians and fiduciaries will be requested to forward soliciting material to beneficial owners of stock held of record by them, and we will reimburse those persons for their reasonable expenses in doing so.

Only holders of record of outstanding shares of common stock of the Company at the close of business on April 4, 2014 are entitled to notice of, and to vote at, the annual meeting. Each stockholder is entitled to one

vote for each share of common stock held on the record date. There were 69,922,433 shares of common stock outstanding and entitled to vote as of the record date.

The presence, in person or by proxy, of the holders of a majority of the shares of common stock issued and outstanding and entitled to vote at the annual meeting is necessary to constitute a quorum to conduct business. Abstentions and “broker non-votes” will be counted as present and entitled to vote for purposes of determining a quorum. Brokers have the discretion to vote shares held in “street name”—a term that refers to shares held in the name of a broker on behalf of its customer, the beneficial owner—on matters considered “routine”

under New York Stock Exchange listing rules, such as the ratification of the appointment of independent auditors, but not on other, “non-routine” matters, such as the election of directors or an advisory vote on executive compensation. Broker non-votes generally occur when shares held in street name by a broker for a beneficial owner are not voted with respect to a non-routine matter because the broker has not received voting instructions from the beneficial owner and the broker lacks discretionary authority to vote the shares.

Each director who receives a majority of votes cast (number of shares voted “for” exceeds the number of shares voted “against”) will be elected as a director. With respect to the election of directors, stockholders may (1) vote “for” all of the nominees, (2) vote “against” all of the nominees, (3) vote “against” certain of the nominees but vote “for” the other nominees, or (4) “abstain” from voting on one or more, or all, of the nominees. Shares not present, in person or by proxy, at the annual meeting and abstentions will have no effect on the outcome of the election of directors. Similarly, any broker non-votes will not be considered to be votes cast on the election of directors and therefore will have no effect on the outcome of the election of directors.

The affirmative vote of a majority of the votes cast is required for each of the approval of the advisory vote on executive compensation and ratification of the appointment of independent auditors. With respect to each of these items, stockholders may (1) vote “for,” (2) vote “against,” or (3) “abstain” from voting. Abstentions are not considered to be votes cast and therefore will have no effect on the outcome of the vote on these matters. In addition, with respect to the advisory vote on executive compensation, broker non-votes are not considered to be votes cast and therefore will have no effect on the outcome of the vote on this matter. As the ratification of the appointment of independent auditors is a routine matter under New York Stock Exchange listing rules, there will be no broker non-votes with respect to this matter.

To attend the annual meeting, you will need to bring an admission ticket (or legal proxy) and valid picture identification. If your shares are registered in your name and you received proxy materials by mail, your admission ticket is attached to your proxy card. If you hold shares through an account with a bank or broker, you will need to contact your bank or broker

and request a legal proxy, which will serve as your admission ticket. Cell phones must be turned off prior to entering the annual meeting. Cameras and video, audio or any other electronic recording devices will not be allowed in the meeting room during the annual meeting, other than for Company purposes.

All of our directors are now subject to annual election by our stockholders. Any vacancies that occur on our Board of Directors, or any newly elected directorships, may be filled by the Board, and any such newly appointed director will serve for the remainder of the unexpired portion of the term of the director who departed, if any, or otherwise until the next succeeding annual meeting of stockholders.

In evaluating director candidates and considering incumbent directors for re-nomination to the Board, the nominating and governance committee may consider a variety of factors, including each nominee’s character, independence, judgment, financial literacy, educational experience, professional experience and personal and professional accomplishments, in light of the needs of the Company. For incumbent directors, factors considered by the committee also include the nominee’s past performance on the Board and contributions to any Board committees on which the nominee has served.

On March 4, 2014, Stephen E. Macadam gave notice of his decision not to stand for re-election as a member of the Board at the Company’s 2014 annual meeting of stockholders. Mr. Macadam has been a director of the Company since 2009. He will continue to serve the remainder of his term as a director until his term expires at the 2014 annual meeting. In response to Mr. Macadam’s decision, the Board intends to reduce the size of the Board from eleven directors to ten. Accordingly, the Board has nominated ten director nominees for election to the Board at the 2014 annual meeting.

As a result of all of the foregoing, the following director nominees are proposed for election to the Board, to serve until the Company’s next annual meeting of stockholders, and until their respective successors are duly elected and qualified:

The nominating and governance committee, and the other members of the Board, believe this slate of director nominees has the appropriate mix of educational and professional experiences, specific areas of expertise, skills and qualifications that are appropriate to enable the Board to successfully address the needs and challenges of the Company and its various business segments. In addition, each of these director nominees has proven his or her leadership, integrity and sound judgment during the time that he or she has served on the Board.

Unless instructed otherwise, properly executed proxies will be voted for the election of all ten of the nominees named above. If any such nominee is unwilling or unable to serve (an eventuality of which we are not currently aware), proxies may be voted for a substitute nominee selected by the Board, or the Board may determine to reduce the number of nominees.

This experience gives him unique knowledge of the Company’s history and the opportunities and challenges associated with the Company’s businesses and operations. Mr. Fleming also served as the chairman of the Board’s compensation committee from May 2004 until February 2008, an experience that gives him valuable insight into the executive compensation issues the Board must address on a regular basis. In addition, Mr. Fleming’s experience as Managing Director and Chief Executive Officer of a complex, international joint venture in the gas industry, as well as his experience in various senior management positions in the natural gas industry before that, give him a unique and important understanding of, and insight into, an industry that supplies the Company with one of its most critical energy requirements, including an understanding of the factors impacting the pricing, availability, distribution and logistics related thereto.

These positions, combined with the sophisticated transactional work Mr. Gervis managed while he was a partner at the international law firm of Weil, Gotshal Manges, gives Mr. Gervis significant insight into, and understanding of, the methods and processes used to assess and evaluate potential investment opportunities and other complex transactions that may be presented to the Company. In addition, because Mr. Gervis has served on many boards and investment committees and currently serves on two for-profit boards of directors, he has substantial experience regarding how boards can and should effectively oversee and manage companies, and a significant understanding of governance issues.

The Company’s Corporate Governance Guidelines require that a majority of our directors meet the independence standards of the New York Stock Exchange listing requirements and applicable SEC rules. In addition, in determining director independence, the Board considered any pre-existing relationships between each director and PPG Industries, Inc. Under these criteria, the Board has determined that each of Messrs. DeNicola, Fleming, Gervis, Macadam, Mansfield, Noetzel, Ripp and Weinstein and Dr. Haynes meet these standards for independence and are independent of management.

Our Corporate Governance Guidelines, as well as our Code of Business Ethics, are publicly available on our website at www.axiall.com under “Investors-Governance” or available in print to any stockholder by contacting Investor Relations, Axiall Corporation by mail at 1000 Abernathy Road, Suite 1200, Atlanta, Georgia 30328 or by phone at (770) 395-4500.

A majority of the members of our Board joined the Board at or after the time of our 2009 financial and operational restructuring. Particularly since its 2009 recomposition, our Board has a demonstrated track record of implementing governance structures and practices that we believe are favorable towards, and promote accountability to, the Company’s stockholders. In recent years, those steps have included:

• amending the Company’s charter and bylaws to declassify the Board;

• maintaining the separation of the chief executive officer and Board Chairman roles, an approach that was adopted in 2008;

• implementing a majority voting requirement for uncontested director elections;

• adopting a policy that requires any director who fails to obtain the required vote to offer to resign;

• adopting a policy that prohibits directors, officers and certain other Company employees from engaging in short-selling transactions with respect to the Company’s common stock;

• adopting a policy that prohibits directors, officers and certain other Company employees from engaging in hedging transactions with respect to the Company’s common stock; and

• adopting a policy that generally prohibits directors, officers and certain other Company employees from pledging Company securities, except in very limited circumstances.

The compensation of directors is determined by the Board following a recommendation by the nominating and governance committee, which reviews such compensation on a periodic basis. In May 2013, the nominating and governance committee recommended adjustments to the amount and nature of director compensation in order to reflect the larger size of the Company and the increased complexity of the Board’s duties following the Company’s merger with the Merged Business, and to more closely align director compensation with its peer companies following the merger. Effective as of May 21, 2013, our non-employee directors are entitled to the following:

• an annual fee of $80,000, which each non-employee director may elect to be paid in Company common stock or cash;

• an annual equity grant of restricted stock units (“RSUs”) valued at approximately $100,000;

• an additional fee of $1,000 per Board or committee meeting for every official meeting over a threshold of 25 official meetings per year that each such director attends;

• an additional annual retainer with respect to each Board committee on which each non-employee director serves (unless the director serves as the chair of the committee) in the amounts of $10,000 for serving as a member of the audit committee, $7,500 for serving as a member of the leadership development and compensation committee, $5,000 for serving as a member of the finance committee and $5,000 for serving as a member of the nominating and corporate governance committee;

• the Board’s non-executive Chairman is paid an additional annual fee of $80,000, the chairman of the audit committee is paid an additional annual fee of $25,000, the chairman of the leadership development

and compensation committee is paid an additional annual fee of $15,000 and the chairman of each other committee of the Board is paid an additional annual fee of $10,000; and

• non-employee directors are also eligible to participate in our 2011 Equity and Performance Incentive Plan (the “2011 Plan”), which was amended in January 2013 to limit the aggregate amount of stock or stock-based awards which a non-employee director could be granted under the 2011 Plan during any calendar year to a value as of their respective dates of grant of $300,000.

On March 5, 2013, Dr. Haynes and Messrs. McGarry and Ripp each received an initial grant of 745 time-based RSUs under the 2011 Plan in connection with his or her agreement to serve on, and appointment to, the Board. These RSUs represent such director’s pro rata share, or approximately 31%, of the number of time-based RSUs granted to other non-employee directors in May 2012, which were expected to, and did, vest in May 2013.

In May 2013, each non-employee director received a grant of 2,053 time-based RSUs under the 2011 Plan. These time-based RSU awards vest on the earlier of the first anniversary of the date of grant or the day immediately preceding the next annual meeting of stockholders. Directors are also eligible to defer compensation into the Company’s Deferred Compensation Plan described under the caption “Compensation Discussion and Analysis—Summary of Our 2013 Executive Compensation Program—Non-Qualified Deferred Compensation Plan.”

The following table details compensation provided to each non-employee director who served as a member of our Board in 2013. For information on the compensation paid to Mr. Carrico, see the Summary Compensation Table elsewhere in this proxy statement.

The audit committee of the Board consists of T. Kevin DeNicola (Chairman), Patrick J. Fleming and William L. Mansfield. Each member of the audit committee has the ability to read and understand financial statements, and the Board has determined that each member of the audit committee is “independent” as defined by the New York Stock Exchange listing requirements and Rule 10A-3 under the Securities Exchange Act of 1934. The Board has also determined that T. Kevin DeNicola is an “audit committee financial expert” as that term is defined by SEC rules. In making such determination, the Board took into consideration, among other things, the express provision in Item 407(d) of SEC Regulation S-K that the determination that a person has the attributes of an audit committee financial expert shall not impose any greater responsibility or liability on that

person than the responsibility and liability imposed on such person as a member of the audit committee and the Board, nor shall it affect the duties and obligations of other audit committee members or the Board. The primary functions of the audit committee are to review the adequacy of the system of internal controls and management information systems, to review the results of our independent registered public accounting firm’s quarterly reviews of our interim financial statements, and to review the planning and results of the annual audit with our independent registered public accounting firm. The audit committee also has responsibilities related to the oversight of the Company’s overall risk management process. This committee held ten meetings in 2013.

The finance committee of the Board consists of David N. Weinstein (Chairman), Robert M. Gervis, Mark L. Noetzel and Michael H. McGarry, who was appointed to the finance committee effective January 28, 2013. This committee’s primary functions include overseeing the financial plan, policies and practices of the Company. More specifically, the duties of the committee include: (1) evaluating and monitoring the Company’s capital structure and any proposed adjustments to that structure, including working capital and cash-flow management and short-term investment policies;

(2) reviewing any proposed capital or debt issuances or repurchases; (3) reviewing commercial and investment banking relationships and activities; (4) reviewing potential acquisitions, divestitures or investments in new businesses or joint ventures; (5) reviewing the funding for, and reports regarding the asset investment strategy of, the Company’s employee benefit plans; and (6) reviewing the Company’s investor profiles and related investor relations programs. This committee held six meetings in 2013.

The leadership development and compensation committee of the Board consists of Stephen E. Macadam (Chairman), T. Kevin DeNicola, David N. Weinstein and William L. Mansfield, who was appointed to the committee effective September 11, 2013. The primary functions of the leadership development and compensation committee include overseeing our executive compensation and equity and performance

incentive compensation plans and policies. This committee has the authority to retain, compensate and oversee compensation consultants. For additional information regarding the processes and procedures for consideration and determination of executive compensation, see the Compensation Discussion and Analysis starting on page 26 of this proxy statement. This committee held four meetings in 2013.

The nominating and governance committee consists of Robert M. Gervis (Chairman), Patrick J. Fleming, Victoria F. Haynes, who was appointed to the committee effective January 28, 2013 and Robert Ripp, who was appointed to the committee effective September 11, 2013. William L. Mansfield was a member of this committee in 2013 prior to being removed from the committee at his request, and simultaneously being appointed to the leadership development and compensation committee, effective September 11, 2013. This committee’s primary functions are: (1) identifying individuals qualified to become members of the Board; (2) recommending director nominees for each annual meeting of stockholders, and nominees to fill any Board vacancies; (3) evaluating and making recommendations to the Board regarding director compensation and continuing education; (4) monitoring and evaluating legal and regulatory trends and other developments relating to corporate governance matters, including trends in stockholder activities; and (5) making recommendations to the Board regarding corporate governance policies and practices. This committee held four meetings in 2013.

This committee may select candidates based on their character, judgment, business experience and specific areas of expertise, among other then-relevant considerations, such as the requirements of applicable law and listing standards. Given the evolving needs and challenges of the Company’s business, the selection process at any time may emphasize different qualities based on, among other things, the Board’s diversity and composition at the relevant time, giving due consideration to a number of factors which may include differences with respect to personal, professional or educational experience, the nature and geographic scope of business experience and its relevance to the Company’s strategy, and the ability to commit the time required to understand the Company’s business. The committee recommends new Board members in

consultation with the other non-management Board members, executive management and external consultants. This committee has the authority to retain, and from time to time in the past has retained, an executive search firm to assist in the identification of potential director candidates.

This committee will consider nominees recommended by stockholders on the same terms as those recommended by any search firm or selected by the committee. Any recommendation should be addressed in writing to the Nominating and Governance Committee, c/o the Corporate Secretary, Axiall Corporation, 1000 Abernathy Road, Suite 1200, Atlanta, Georgia 30328.

Stockholders may recommend candidates at any time, but to be considered by the committee for inclusion in the Company’s proxy statement for the next annual meeting of stockholders, as long as any such stockholder is a stockholder of record at the time of the next annual meeting, and the stockholder (or a qualified representative) appears at that annual meeting. Any such nominations must be submitted in writing at least 60 days but no more than 90 days in advance of the first anniversary of the date the Company’s proxy statement was first mailed to stockholders for the preceding year’s annual meeting of stockholders. A stockholder’s notice must contain the following:

• with respect to the nominating stockholder:

• with respect to the proposed nominee:

The Board believes that its leadership structure, including any potential combination or separation of the CEO and Chairman roles, should be determined based upon the specific needs of the Company, and what is determined to be in the best interests of the Company’s stockholders from time to time. As a result, no written policy exists requiring either the combination or separation of the Chairman and CEO leadership roles, and the Company’s governing documents do not mandate a particular structure. This provides the Board with the flexibility to establish what it believes, in the exercise of its judgment, is the most appropriate leadership structure for the Company at any given time.

The Chairman of the Board provides leadership to the Board and works with the Board to provide guidance with respect to how the Board defines its structure and prioritizes and carries out its duties and responsibilities. In addition to presiding at Board meetings and executive sessions of the Board, the Chairman’s duties include working with management and the chairmen of the Board’s various committees to: (1) schedule and call Board meetings; (2) establish the agenda for each Board meeting; (3) review and determine the appropriate materials to be provided to directors; (4) monitor and address recent developments in corporate governance and the Company’s assessment of, and responses to, corporate governance issues; (5) encourage and facilitate active and constructive participation from all directors; and (6) facilitate communications between the Board and management. In addition, the Chairman serves as a conduit for communications from the Board to the Company’s management team, and plays a significant role in overseeing the effectiveness of the Company’s approach to risk management. Mr. Noetzel has served as the Chairman since January 2010.

The Board believes a leadership structure that separates the CEO and Chairman positions continues to be appropriate for the Company at this time for a variety of reasons. The Board will continue to evaluate this arrangement in the future, as part of its regular reviews of corporate governance matters. In the event the Board decides to consolidate the CEO and Chairman positions, thereby making the CEO the Chairman, the Board anticipates it would appoint a lead director.

All of the Company’s directors play an active role in overseeing the Company, both at the Board and Board-committee levels. As set out in the Company’s Corporate Governance Guidelines, our directors’ core responsibility is to exercise their business judgment to act in what they reasonably believe to be the best interests of the Company and its stockholders. Our Board includes only one director who serves as a member of the Company’s executive management team (Mr. Carrico, our CEO) and otherwise consists of ten non-employee directors. Our non-employee directors are skilled and experienced leaders in business, each bringing decades of valuable experience to the Board in subject areas that include accounting and finance, legal, capital markets, manufacturing, operations and logistics, and sales and marketing. In these roles, our directors have been called upon to review, evaluate and solve a wide range of complex issues, and to develop and implement many challenging and important business initiatives, plans, policies and strategies, which makes them well-qualified to oversee our Company, and to provide advice and counsel to our CEO and other senior officers of the Company.

The Board’s responsibilities include overseeing the management of the Company’s risks and approach to risk management. The Board evaluates and considers risks within the context of the business and other operational decisions that the Board and management team face, and as part of the Company’s business plans and strategies. The Board understands that it is neither realistic nor prudent to eliminate all risk. In fact, the Board believes purposeful and appropriate risk-taking is necessary for the Company to be competitive

and to achieve its business objectives. As such, part of the Board’s risk-related duties include considering, understanding and overseeing what level of risk is appropriate for the Company, given the nature of the particular risk being considered.

While the Board maintains ultimate responsibility for oversight of the Company’s risk management, the Board implements its risk oversight function both as a whole and through its various committees, which meet regularly with, and report to, the full Board. The

audit committee has been assigned responsibility for oversight of the overall risk management process. In addition, each of the Board’s committees has been assigned responsibility for risk management oversight of specific areas. More specifically:

• The audit committee oversees risks related to the Company’s audit process, financial statements, financial reporting process (including internal control over financial reporting), disclosure controls and procedures, accounting matters and various ethical and legal matters. The audit committee oversees the Company’s internal audit function and ethics program;
   
• The leadership development and compensation committee evaluates and oversees the risks and rewards associated with the Company’s compensation philosophies, plans and policies, reviewing and approving compensation plans and policies with the objective of mitigating compensation-related risk, without unduly diminishing the incentive-based nature of the compensation;
   
• The finance committee oversees risks related to the Company’s financial position and financing activities, including as they relate to the Company’s capital structure and any proposed adjustments to that capital structure, capital and debt issuance and related credit or debt agreements, commercial and investment banking relationships, acquisitions, divestitures and investments in new businesses or joint ventures, the issuance or repurchase of equity or debt securities, as well as the funding for and asset investment strategy of the Company’s employee benefits plans; and
   
• The nominating and governance committee oversees risks related to the Board member nomination process, and risks related to the proposed adoption of various corporate governance policies and principles. In addition, this committee is charged with developing and recommending to the Board changes in corporate governance policies and principles, Board committee structures, as well as leadership and membership to enable the Board and its committees to effectively carry out their respective risk oversight responsibilities.

As a part of the risk oversight process, each committee meets privately in separate sessions with appropriate members of management, and its advisors, as it deems appropriate.

As part of its risk management process, the Company maintains a toll-free hotline that employees and other stakeholders may use to anonymously report alleged violations of the Company’s Code of Business Ethics, health and safety-related policies and rules, employment laws and regulations, and any alleged violations of other laws, regulations, rules or policies. In addition, employees may use the toll-free hotline to anonymously report allegations of questionable activities relating to accounting, internal controls or audit matters. The third-party service provider that maintains the hotline notifies the Company of any calls received. All such calls are addressed promptly by either the Company’s Corporate Compliance Director or a Corporate Compliance Assistant, who is an employee in the Company’s human resources department.

If any calls to the hotline allege questionable activities or violations that are not related to accounting, internal control or audit matters, the Corporate Compliance Director and/or a Compliance Committee will respond to the allegations in an appropriate manner. If any call to the hotline alleges questionable activities related to accounting, internal control or an audit matter, the Corporate Compliance Director will notify the Company’s Director of Internal Audit, who in turn will notify the Chairman of the audit committee. Thereafter, the matter will be brought to the attention of the other members of the audit committee and, depending on the nature of the allegations, to the Chairman of the Board. The audit committee has the power to authorize internal and external investigations of such allegations, and to ensure that appropriate resources are provided for conducting any such investigation. The Company believes its toll-free hotline, and the processes activated by calls to the hotline are important in helping the Company mitigate its exposure to harmful risks.

Because overseeing risk is an ongoing process and inherent in the Board’s and Company management’s decision-making processes, the Board discusses the Company’s various risks throughout the year at its regularly scheduled or, if deemed appropriate, special meetings, in relation to specific proposed actions

and/or newly obtained information about previously discussed risks. Additionally, at one or more meetings of the full Board each year, the Board devotes a portion of its meeting time to evaluating and discussing risks, the steps Company management is taking to mitigate such risks, and other potential risk mitigation strategies

or programs that may be considered appropriate or desirable. At any such meetings, or at other times as determined appropriate, the Board has access to management personnel with knowledge and insight into specific issues for consideration.

Any stockholder or interested party is welcome to communicate with the Chairman of the Board, any other director, the non-employee directors as a group or the Board by writing to the directors or the Board, c/o the Corporate Secretary, Axiall Corporation, 1000 Abernathy Road, Suite 1200, Atlanta, Georgia 30328. The Corporate Secretary will review the communications and will, within a reasonable period

of time after receiving the communications, forward all communications to the appropriate director or directors, other than those communications that are merely solicitations for products or services or relate to matters that are of a type that are clearly improper or irrelevant to the functioning of the Board or the business and affairs of the Company.

The Board of Directors held six meetings in 2013. All incumbent directors attended no fewer than 75% of the aggregate number of meetings of the Board and the committees on which they served during 2013. The Company encourages its directors to attend its annual

stockholders’ meeting. In 2013, all of our directors attended the annual meeting. None of our directors or executive officers is related to any of our other directors or executive officers.

The following table lists information as of April 4, 2014 about the number of shares of our common stock beneficially owned by each incumbent director, each executive officer listed on the summary compensation

table included in this proxy statement, all of our directors and current executive officers as a group, and each person or group known by us to own more than 5% of our common stock.

Section 16(a) of the Securities Exchange Act of 1934 requires our directors and executive officers and persons who own more than 10% of our common stock to file reports regarding their beneficial ownership of our common stock. Based solely upon a review of those

filings furnished to us and, written representations in the case of our directors and executive officers, we believe all reports required to be filed by Section 16(a) with the SEC were timely filed in 2013.

In this section of the proxy statement, we will describe the important components of our executive compensation program for our named executive officers, or “NEOs,” whose compensation is set forth in the 2013 Summary Compensation Table on page 46 of this proxy statement, and in other compensation tables described elsewhere in this proxy statement. For 2013, our NEOs were:

• Paul D. Carrico, our President and Chief Executive Officer;
   
• Gregory C. Thompson, our Chief Financial Officer;
   
• Joseph C. Breunig, our Executive Vice President, Chemicals;

• Mark J. Orcutt, our Executive Vice President, Building Products; and
   
• Timothy Mann, Jr., our Executive Vice President, General Counsel and Secretary.

This section of the proxy statement also provides an overview of our compensation philosophy and program, and explains how and why the leadership development and compensation committee (the “Committee”) determined the specific compensation policies and decisions involving the NEOs.

We are a leading North American manufacturer and international marketer of chemicals and building products, with annual sales of approximately $4.66 billion for the year ended December 31, 2013, and operations in Canada, Taiwan and the United States. Through our numerous subsidiaries, we manufacture and sell a wide array of chemicals products, including: chlorine, caustic soda, vinyl chloride monomer, chlorinated solvents, calcium hypochlorite, ethylene dichloride, muriatic acid, phosgene derivatives,

polyvinyl chloride, vinyl compounds, acetone, cumene and phenol. We also manufacture and sell vinyl-based building and home improvement products, including window and door profiles, mouldings, siding, pipe and pipe fittings, and decking. For more information about our business, please see “Item 1, Business” and “Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the Original 10-K Filing.

We believe 2013 was a transformational year for Axiall due to the leadership of our Board and executive officers, and the dedication and hard work of our employees. In January 2013, we completed the merger with the chemicals business of PPG Industries, Inc. (the “Merged Business”) and focused on integrating the two businesses and leveraging the combined business to achieve one of our primary strategic initiatives, increased chlorovinyls integration.

Primarily as a result of the Company’s merger with the Merged Business, 2013 was our fourth consecutive year of improved financial performance. During 2013, some of our significant accomplishments included:

• obtaining the following benefits from the Company’s merger with the Merged Business:

• achieving approximately $100 million of annualized cost synergies in 2013 from improved procurement and logistics, reduced general and administrative expense and improved operating rates, as a result of the ongoing integration of the Merged Business;

• improving our financial performance, primarily due to the Company’s merger with the Merged Business:

• making substantial progress towards a proposed partnership with Lotte Chemical to develop an ethane cracker in Louisiana, which is expected to provide the Company access to cost-based ethylene in future years;
   
• increasing the Reported Adjusted EBITDA of our building products segment to $70.7 million for 2013, a 23% improvement compared to 2012;⁽⁶⁾
   
• increasing building products net sales generated by innovative new products by more than 70% from the previous year; and
   
• paying three cash dividends to our stockholders, totalling $22.2 million.

The graph below presents a comparison of the cumulative total return⁽⁷⁾ of an investment in each of Axiall Corporation common stock, the Standard & Poor’s 400 Chemicals Index and the Standard & Poor’s 400 MidCap Index from July 29, 2009, the date we completed a significant financial and operating restructuring and related 1-for-25 reverse stock split, until December 31, 2013. We believe this graph, as well as other information presented in this proxy statement and information presented in the “Original 10-K Filing”, should be considered by investors when evaluating our recent results of operations and stock price performance.

CUMULATIVE TOTAL RETURN
OF INVESTMENT IN AXIALL STOCK
AND BENCHMARK INDICES
FROM JULY 29, 2009 TO DECEMBER 31, 2013

Consistent with our compensation philosophy and objectives, during 2013 the Committee took the following compensation-related actions:

• provided annual cash incentive compensation opportunities based on performance against a combination of various Adjusted EBITDA⁽⁸⁾, operational and strategic goals;
   
• granted all of our NEOs long-term, equity incentive awards that do not fully vest until three years after the grant date, thereby aligning the long-term interests of our NEOs with those of our stockholders;
   
• provided that 83% of our CEO’s 2013 target direct compensation⁽⁹⁾ and, on average, approximately 70% of our other NEOs’ 2013 target direct compensation was incentive-based, and thus, “at risk;”

• adjusted the CEO’s base salary by approximately 8.4% and each of the other NEOs’ base salaries by approximately 3%, on average, to reflect the increased size and complexity of the Company and the nature of its business operations after the combination with the Merged Business; and
   
• adopted the Axiall Corporation Executive Officer and Key Employee Severance Plan (the “Severance Plan”) to offer market competitive severance to our NEOs and other executive officers and key employees.

We strive to maintain effective governance standards, including with respect to the oversight of our executive compensation policies and practices. To that end, in 2013:

• the Committee continued to consist solely of independent directors as defined by NYSE listing requirements and Rule 10C-1 under the Exchange Act, whose decisions regarding the compensation of our CEO were made in executive sessions that were not attended by any executive officers, including the CEO;
   
• the Committee recommended to the non-management members of the Board for their ratification the types and amounts of compensation for the CEO, and the Board ratified the Committee’s recommendations in an executive session that was not attended by any executive officer, including the CEO;

• the Board recommended the approval of, and our stockholders approved by more than 99%, the compensation of our executive officers in an advisory “say-on-pay” stockholder vote taken in 2013, that will be taken again in 2014 — we expect this annual say-on-pay vote to continue for the foreseeable future;
   
• the Committee’s independent compensation consultant, Semler Brossy Consulting Group, was retained directly by the Committee and did not provide any services to management;
   
• the Committee evaluated whether there was any conflict of interest with respect to Semler Brossy and certain of its employees providing executive compensation consulting services to the Committee, and concluded (after taking into account the six factor test adopted by the SEC and NYSE) that Semler Brossy was independent and no such conflict of interest existed;

• the Committee conducted an annual review with its compensation consultant of the nature and amount of compensation paid to the executive officers of a peer group of chemicals and building products companies (with characteristics similar to the Company) so that the compensation paid to the Company’s executive officers would be competitive, aligned with our compensation philosophy, and take into account the Company’s merger with the Merged Business in early 2013; and
   
• the Committee conducted a review of our compensation philosophy and objectives and compensation-related risks arising from the compensation policies and practices for all employees, and determined that such risks were not reasonably likely to have a material adverse effect on the Company.

In addition, our compensation philosophy and objectives contain several specific elements that are designed to align our executive compensation with the long-term interests of our stockholders, including:

• stock ownership guidelines that emphasize the importance of substantive, long-term share ownership by both directors and executive officers, so as to better align their financial interests with those of our stockholders, and place responsibility on the CEO to attain Company stock ownership at 5 times his base salary and other NEOs to attain Company stock ownership at 2.5 times their base salaries;
   
• none of our executive officers having multi-year guarantees of compensation;
   
• a policy allowing the Company to “clawback” any incentive compensation paid or granted to any executive officer based on financial results that subsequently are restated as the result of the executive’s fraudulent or illegal conduct;

• provisions in our equity awards granted after May 2011 that require a “double-trigger” for accelerated vesting in connection with a change of control;
   
• a May 2011 amendment to our Executive and Key Employee Change of Control Severance Plan (the “Change of Control Plan”) that eliminates the excise tax gross up benefit that had been provided under that plan, with respect to any person who becomes an executive officer on or after May 16, 2011 (including any person newly hired by the Company and any person promoted from within the Company from a non-executive officer position to an executive officer position on or after that date);
   
• a January 2013 amendment to our 2011 Plan that limits the aggregate amount of stock or stock-based awards that could be granted to a non-employee director under the 2011 Plan during any calendar year to a value as of their respective dates of grant of $300,000;
   
• policies that prohibit directors, officers and certain other Company employees from engaging in short-selling or hedging transactions with respect to the Company’s common stock or pledging Company securities (except in limited circumstances); and
   
• a policy of providing only limited perquisites to our executive officers in the form of a Company car or car allowance, the value of which is disclosed in the table set forth in footnote (4) to the Summary Compensation Table beginning on page 46 of this proxy statement.

Our executive compensation philosophy, which was established by the Committee and approved by the Board, is to: (1) reward favorable Company and business unit financial, operational and strategic performance, as well as stock price performance; and (2) deliver total compensation and benefits at target performance levels approximating the median compensation and benefits paid by similar companies in the chemicals

and building products sectors, with the ability to pay above or below that median as the Company’s and/or individual executive officer’s performance varies, and also taking into account factors such as an officer’s role and responsibilities, experience and tenure, prior performance, actual and expected contributions, and internal pay equity considerations.

The Committee designed the executive compensation programs in place during 2013 to be consistent with that compensation philosophy. Specifically, the Committee observed the following guiding principles that emerge from our compensation philosophy:

• Compensation Should Be Performance-Based: A substantial portion of the total compensation opportunity should reflect and reinforce a “pay for performance” culture favoring performance-based cash and equity incentive compensation in lieu of salary, supplemental benefits or executive perquisites, and should vary based upon our financial, operational and strategic performance against pre-established goals, and the long-term value of the Company;

• Compensation Should Be Aligned with Stockholder Interests: Our compensation programs should align the interests of executive officers with the long-term interests of our stockholders by providing strong incentives to maximize long-term value for our stockholders, while balancing acceptable risks through the use of stock ownership guidelines and “clawback” policies applicable to executives; and
   
• Compensation Should Be Market Competitive: Our success is heavily dependent on our ability to attract and retain experienced executive officers who are proven leaders, and to motivate them to consistently deliver positive strategic and financial results. As a result, overall compensation should be structured to present an attractive package to existing and potential executive officers.

We maintain stock ownership guidelines to emphasize the importance of substantive, long-term share ownership by executive officers intended to align their financial interests with those of stockholders. We also have share ownership guidelines in place for our directors. The guidelines are denominated as a multiple of base salary for the executive officers, and a multiple of the annual retainer for directors.

Each executive officer and non-employee director has five years as an officer or director, respectively, to attain stock ownership and compliance with the stock ownership requirements annually. All of the individuals named in the Summary Compensation Table below who are required to comply with this policy (based on hire date) are currently in compliance with these minimum stock ownership requirements. Mr. Breunig, who was hired in September 2010, and Mr. Mann, who was hired in July 2012, have until September 2015 and July 2017, respectively, to comply with the guidelines.

Our Board has also adopted a policy that provides, to the extent permitted by law, that if the Board, or any committee, determines that any bonus, incentive payment, equity award or other compensation has been awarded to or received by an executive officer and such compensation was based on any financial results or operating metrics that were subsequently the

subject of a material restatement as a result of such officer’s knowing or intentional fraudulent or illegal conduct and a lower payment would have been made to the officer based on the restated results, then the Board has the right to recover (“clawback”) from the officer such compensation (in whole or in part) as it deems appropriate under the circumstances.

The Committee specifically designed certain of our 2013 performance-based RSUs to discourage unnecessary risk-taking that is not in the Company’s long-term interests. In particular, the Committee granted certain performance-based RSUs that vest based on the Company’s achievement of a specified cost synergy target, but recognized that cost synergies should not be achieved at the expense of the long-term growth and financial objectives of the Company. Accordingly, these 2013 performance-based RSUs also included a threshold Adjusted EBITDA target for the period from January 1, 2013 through December 31, 2014. If this threshold, which the Committee believes requires the applicable NEOs to work to achieve the specified cost synergies target without taking actions that may maximize synergies achievement in the short-term, but are harmful to the long-term growth and financial performance of the Company, is not achieved, no performance-based RSUs will be earned.

In addition, the Committee determined in March 2014 that the performance metrics for performance-based RSUs granted in 2014 will be based on a relative total shareholder return, defined as share price appreciation and dividends paid, assuming those dividends are reinvested as paid, and these performance-based RSUs will cliff vest on the third anniversary of the grant date if the performance metrics are achieved. The comparator group will consist of 45 chemical companies from the S&P 1500. The Committee believes that the use of relative total shareholder return as the relevant performance metric discourages unnecessary risk-taking by aligning our NEOs’ long-term compensation with the long-term performance of the Company, and accordingly, with the long-term interests of the Company’s shareholders.

We provide our stockholders with the opportunity to vote annually on a say-on-pay proposal. At our 2013 annual meeting of stockholders held on May 21, 2013, approximately 99% of the votes cast by stockholders on the advisory vote on executive compensation (the “say-on-pay proposal”) were in favor of the compensation of

our named executive officers. The Committee believes this favorable vote affirms our stockholders’ support of its approach to executive compensation and, as a result, the Committee did not make material changes to the implementation of our executive compensation philosophy in 2013.

The Committee continually reviews the design and administration of our executive compensation policies and programs to ensure they appropriately reflect our compensation philosophy. Any program changes that are made are driven by the Committee’s desire to maintain alignment with stockholder interests and to be consistent with the guiding philosophy and objectives referenced above.

The Committee considers the tax and accounting implications of compensation, but those are not the only factors considered, as the Committee also considers all of the other factors discussed in this Compensation Discussion and Analysis when making compensation decisions. The Committee recognizes that one or more of these other factors may outweigh tax or accounting considerations.

Section 162(m) of the Internal Revenue Code (the “Code”) limits deductibility of certain compensation for our CEO and the three other executive officers (other than the Chief Financial Officer) who are highest-paid and employed at year-end to $1 million. If certain conditions are met, performance-based compensation may be excluded from this limitation.

While we believe it is in our Company’s and our stockholders’ best interests to have the ability to grant qualified performance-based compensation under Section 162(m) of the Code, we may decide to grant compensation that will not qualify as qualified performance-based compensation for purposes of Section 162(m) of the Code. Moreover, even if we intend to grant compensation that qualifies as qualified performance-based compensation for purposes of Section 162(m) of the Code, we cannot guarantee that such compensation ultimately will be deductible by us.

The Committee evaluates and administers the compensation of our executive officers in a holistic manner, makes compensation decisions around program design, and adjusts pay in light of our compensation philosophy, market practices and total compensation objectives. The Committee ordinarily positions the various compensation elements at levels it believes are targeted to be at or near the median of compensation paid by the market references, but that positioning for any executive officer is also dependent upon an officer’s role and responsibilities, experience and tenure, prior performance, actual and expected contributions and internal pay equity considerations. Market positioning of the individual elements of

compensation and benefits, as well as the relationships among these elements, are described in the sections that follow.

With respect to the proposed compensation for the CEO, the Committee determines, approves and recommends to the Board for ratification all compensation, equity and benefits to be paid to the CEO based on an evaluation of the CEO’s performance in light of corporate goals and objectives that were previously approved by the Committee and ratified by the non-management members of the Board.

For the other executive officers, and within the constructs of any applicable employment agreement that may have been negotiated and entered into by the Company, the Committee considers all appropriate factors, including the recommendations of the CEO, in reaching its decisions. The CEO’s recommendations are considered for approval by the Committee, and in some cases are modified by the Committee during the course of its deliberations.

In setting and evaluating annual compensation of the Company’s executive officers, the Committee reviews and considers, among other factors, the pay mix, which is the percentage of total compensation represented by each element of compensation, of each of the Company’s executive officers, as compared to the Company’s “market references” described below. The actual pay mix for each of the Company’s NEOs for 2013, which differs from the target awards described under “Annual Cash Incentive Opportunity” and “Long-Term Equity Based Awards”, was as follows:

Within the parameters of the compensation philosophy and objectives established by the Committee and/or Board, each year our CEO recommends to the Committee the level of base salary, the target annual cash/non-equity incentive award and the target long-term equity incentive award for each of the other executive officers. The recommendations of our CEO are based on his evaluation of each executive officer’s performance, the performance of the

individual business units or functions for which that executive officer is responsible and management retention considerations. The Committee considers the CEO’s recommendations, along with all other appropriate factors, in reaching its decisions regarding the compensation of each executive officer. In some cases, the CEO’s recommendations are modified by the Committee during the course of its deliberations.

Our Board reviews and ratifies the recommendations of the Committee with respect to: (1) the design of incentive compensation plans for the Company’s executive officers; (2) any significant changes to compensation guidelines and benefit plans for the Company’s executive officers; and (3) significant changes to

benefit programs for the Company’s executive officers. In addition, the Committee determines, and then recommends to the non-management members of the Board for their ratification all compensation, equity and benefits to be paid to the CEO (with the CEO not participating in those deliberations).

As a part of its responsibilities, the Committee has the authority to appoint, compensate and oversee the Company’s outside compensation consultant. In 2013, the Committee retained Semler Brossy Consulting Group as its consultant to assist the Committee with its responsibilities related to the Company’s compensation policies and programs for its executive officers. In addition, in 2013, the Board’s nominating and governance committee retained Semler Brossy as its consultant to assist that committee with its responsibilities related to the Company’s compensation policies and programs for its directors. Semler Brossy did not provide any services unrelated to executive officer and director compensation consulting to any Board committee or to the Company during 2013. The Committee has taken into account the six factor test adopted by the SEC and the NYSE to analyze the independence of Semler Brossy, and determined that Semler Brossy is independent and that their work does not raise any conflicts of interest.

The compensation consultant reports directly to the Committee. One or more representatives of the compensation consultant attends the meetings of the Committee, as requested by the Committee chairman, and communicates with the chairman of the Committee between meetings, as needed. The compensation consultant does not make decisions regarding the compensation of our executive officers. Rather, the

compensation consultant provides advice, guidance and information that the Committee and, with respect to certain decisions, our Board, may consider when making executive compensation decisions.

The Committee’s compensation consultant supports the Committee by, at least annually, conducting an independent and comprehensive review of our executive compensation programs, including providing periodic reports showing total remuneration for each executive officer, and an evaluation of total compensation and individual pay elements based upon our market references. In December 2012, the compensation consultant conducted such a review and analysis, and discussed it with the Committee in connection with the Committee’s determination of executive officer compensation for 2013. That review took into account the increased size and complexity of the Company and its operations after the Company’s then-pending merger with the Merged Business and included evaluations of the elements of direct compensation, including: base salary, annual non-equity incentive awards and long-term equity-based incentive awards against our peer group and survey data. In addition, the compensation consultant’s review also considered executive compensation trends and the long-term incentive design for executive officers of the Company.

In conducting the evaluations made by the Committee in its executive compensation decision making, the compensation consultant uses “market references,” which consist of a peer group of chemicals and building products companies with characteristics similar to the Company (based on revenue, market capitalization, assets and/or number of employees) and survey data as discussed below.

In December 2012, our compensation consultant reviewed the market reference peer group taking into account the then-pending merger with the Merged Business. In March 2013, following our combination with the Merged Business, the Committee approved a new market reference peer group designed to more closely align our peer group with the size of the combined Company and the nature of its business operations. The market reference peer group for 2013 consisted of the following 19 companies⁽¹⁰⁾:

In addition, to assess compensation levels, the compensation consultant recommended to the Committee and the Committee utilized data from the Towers Watson U.S. CDB Executive Compensation Survey. The compensation consultant adjusted this

survey data to include samples from general industry companies as well as companies in the chemical or building products industries, adjusted based upon the size of the Company’s annual revenue.

For 2013, the Committee took into account a number of factors in determining the compensation of the executive officers. These factors included, among other things: (1) our compensation philosophy and objectives; (2) the increased size and complexity of the Company and the nature of its business operations after the combination with the Merged Business; (3) actual Company performance in 2013; and (4) actual individual executive officer performance in 2013.

The following sections describe the various elements of our executive compensation program, including the objectives, market positioning, structure and operation, and other information specific to 2013 payments, awards, and pay actions in more detail.

Each NEO is paid a base salary, which is reviewed annually by the Committee. Salaries for NEOs are generally targeted to be at or near the median of salaries paid by the market references, but are also dependent upon the officer’s role and responsibilities, experience and tenure, prior performance, actual and expected contributions, and internal pay equity considerations.

Base salaries for NEOs, including the CEO, were reviewed by the Committee in March 2013 within the context of an overall compensation market reference analysis performed by its compensation consultant. The analysis conducted by the compensation consultant was discussed with the Committee in December 2012

and March 2013. Adjustments to the NEOs’ salaries were approved by the Committee in March 2013, with the CEO’s adjustment being ratified by the non-management members of the Board at that time, and those adjustments became effective in April 2013. Base salaries for the NEOs, other than the CEO, were increased by approximately 3% as compared to 2012 salaries. The CEO’s base salary was increased by approximately 8.4% as compared to his 2012 salary. After giving effect to the salary increases, 2013 base salaries for the NEOs, 2012 base salaries and the year over year percentage increase of the NEO salaries were as follows:

The Committee and Board believe these base salary increases were appropriate because: (1) salaries paid to similarly situated executives at similarly sized companies were higher than our NEO salaries; (2) the Committee believed the Company had continued to make significant progress in improving the Company’s financial performance and in meeting the operational and strategic goals set out for the Company; and (3) the Company planned salary and promotional increases

for its other management and professional employees. In particular, the Committee determined that the increase in the CEO’s base salary was appropriate due to the increased size and complexity of the Company’s business and the nature of its operations following the combination with the Merged Business, and due to the fact that the CEO’s base salary was below the salaries of chief executive officers at similarly sized companies.

The Company’s annual cash/non-equity incentive opportunity program for 2013 was designed so that a portion of the overall annual cash compensation of NEOs was linked to annual corporate financial performance and, with respect to each of Messrs. Breunig and Orcutt, the financial performance of the division that each of them manages, as well as the attainment of certain operational goals, which also were division-specific for each of Messrs. Breunig and Orcutt. This program and the metrics established under it are intended to incentivize superior business

and individual performance, and tie the interests of management to Company performance, and accordingly, to the interests of our stockholders. For 2013, each NEO had a target annual cash incentive award opportunity expressed as a percentage of base salary. Individuals with greater overall responsibility for corporate performance typically have larger incentive opportunities when compared to base salaries in order to weight their overall pay mix more heavily toward performance-based compensation.

The Committee administers the Company’s annual cash incentive opportunity program for the CEO and other NEOs and, as part of that function, determined that 2013 cash incentive compensation payouts for Messrs. Carrico, Thompson and Mann would be based on the following performance metrics and goals, weighted as follows:

• 60% of the award opportunity was to be based upon the Company’s Adjusted EBITDA for 2013; 

• 20% of the award opportunity was to be based upon the level of achievement of the specific and measurable operational goals for (1) the Chemicals division related to gross margin return and Electro Chemical Unit (“ECU”) reliability and (2) the Building Products division related to reductions in conversion costs, the percentage of net sales generated from innovative new products and operating cash flow generated by the Building Products division; and

• 20% of the award was to be based upon the level of achievement of certain specific corporate strategic goals related to information technology infrastructure improvements, strategic initiatives to gain access to cost-based ethylene, the review of our corporate strategic planning process and the expansion of succession planning based on our combination with the Merged Business (the “Corporate Strategic Goals”).

In addition, the Committee determined that, with respect to the evaluation of Mr. Carrico’s cash incentive compensation, it would also consider Mr. Carrico’s level of achievement of goals related to the achievement of cost synergies and the organizational integration of the Merged Business.

The Committee further determined that 2013 cash incentive payouts for Messrs. Breunig and Orcutt would be based upon the following performance metrics and goals, weighted as follows:

• 40% of the award opportunity was to be based upon the Company’s Adjusted EBITDA for 2013; 

• 20% of the award opportunity was to be based upon the Adjusted EBITDA of the Chemicals division, for Mr. Breunig, and the Adjusted EBITDA of the Building Products division, for Mr. Orcutt; 

• 20% of the award opportunity was to be based upon the achievement of operational goals of the Chemicals division, for Mr. Breunig, related to gross margin returns and ECU reliability, and operational goals of the Building Products division for Mr. Orcutt, related to reductions in conversion costs, operating cash flow and the percentage of net sales generated from innovative new products; and 

• 20% of the award opportunity was to be based upon the achievement of the Corporate Strategic Goals.

Adjusted EBITDA is used as the primary measure of performance within each of the Company’s business units, and both the Committee and management believe industry participants commonly use it as a main component of valuation analysis of companies whose businesses may be cyclical, like the Company. The Adjusted EBITDA measure was also selected as a Company performance goal to encourage executive officers to focus on improving corporate performance by controlling corporate expenses, and improving the quality and volume of earnings, which aligned with the Company’s overall business objectives for 2013.

In determining various levels of Adjusted EBITDA at which payouts would be made, the annual cash incentive program provided for adjustments to EBITDA

for certain cost, charge and income items, substantially similar (other than lease financing obligations) to those excluded from adjusted EBITDA in the Company’s public sales and earnings disclosures. The Committee established these targets at levels designed to incentivize superior performance by our NEOs.

The threshold, target and maximum levels of corporate and divisional Adjusted EBITDA used for annual cash incentive program payout purposes were determined by the Committee after review and consideration of the Company’s internally-developed, detailed budgets and forecasts.

The threshold, target and maximum Adjusted EBITDA metrics under the annual cash incentive program for 2013 were as follows:

Under the annual cash incentive program, no payouts would be earned with respect to each Adjusted EBITDA component of that program if the relevant Adjusted EBITDA did not exceed “Threshold.” Payouts would be 100% of target opportunity amounts if Adjusted EBITDA equaled “Target,” and 200% of target opportunity amounts if Adjusted EBITDA equaled or exceeded “Maximum.” Payouts under the Adjusted EBITDA component of the annual cash incentive program would increase in a linear fashion as Adjusted EBITDA increased between “Threshold” and “Target,” and “Target” and “Maximum.”

The Company’s actual Adjusted EBITDA in 2013 was $679.1 million, which was above the “Threshold” level for the portion of the annual cash incentive program tied to Company Adjusted EBITDA, but less than the “Target” level. In addition, the actual Adjusted EBITDA in 2013 for the Chemicals division was above the “Threshold” level for that business, but less than the “Target” level. The actual Adjusted EBITDA in 2013 for the Building Products division was above the “Threshold” level, but less than the “Target” level. The percentage of the “Target” Adjusted EBITDA achieved for each of the Company, the Chemicals division and the Building Products division is set forth in the table below.

In addition to Adjusted EBITDA goals, the NEOs had a combination of corporate and divisional strategic and operational goals for 2013, some of which were targeted within each NEO’s area of responsibility, with no weighting among the specific strategic objectives and operational objectives. Actual performance against

these strategic and operational goals was assessed by the CEO, with respect to the other NEOs (subject to the acceptance of the CEO’s assessments by the Committee) and was assessed by the Committee and the Board with respect to the CEO (with the CEO not participating in that assessment).

In determining the percentage of the 2013 target cash/non-equity incentive opportunity to be paid to each NEO, the Committee considered various combinations of the following factors, depending upon the NEO whose compensation was being evaluated: the amount of the Company’s actual Adjusted EBITDA; the amount of the business-specific Adjusted EBITDA achieved by each of the Chemicals and Building Products divisions; the level of achievement of the Corporate Strategic Goals, the level of achievement of operational goals by each of the Chemicals and Building Products divisions; and,

with respect to Mr. Carrico, his level of achievement of goals related to the achievement of cost synergies and the organizational integration of the Merged Business. After evaluating all of these performance factors and using its discretion to determine the consideration or weight that would be given to certain of the factors, the Committee concluded that each NEO should be paid the percentage of the NEO’s 2013 target cash/non-equity incentive opportunity set forth in the following table:

In March 2014, the Committee established the design of, and performance goals related to, the 2014 annual cash incentive opportunity. Consistent with 2013, the 2014 annual cash incentive opportunity was designed so that a portion of the overall annual cash compensation of NEOs was linked to annual corporate financial performance, and with respect to each of Messrs. Breunig and Orcutt, the financial performance of the division that each of them manages, as well as the attainment of certain operational goals. However, the Committee weighted the various performance metrics differently for 2014 to provide greater incentive for improved performance at the division level.

In particular, for Messrs. Carrico, Thompson and Mann, the performance metrics under the 2014 annual cash incentive opportunity will be weighted as follows:

• 50% of the award opportunity is based upon the Company’s Adjusted EBITDA for 2014;

• 30% of the award opportunity is based upon the level of achievement of the specific and measurable 2014 operational goals for (1) the Chemicals division

related to ECU reliability and other operational goals and (2) the Building Products division related to reductions in conversion costs, the percentage of net sales generated from innovative new products and operating cash flow generated by the Building Products division; and

• 20% of the award is based upon the level of achievement of certain 2014 corporate strategic goals.

In addition, for Messrs. Breunig and Orcutt, the performance metrics under the 2014 annual cash incentive opportunity will be weighted as follows:

• 30% of the award opportunity is based upon the 2014 Adjusted EBITDA of the Chemicals division, for Mr. Breunig, and the 2014 Adjusted EBITDA of the Building Products division, for Mr. Orcutt;

• 20% of the award opportunity is based upon the Company’s Adjusted EBITDA for 2014;

• 30% of the award opportunity is based upon the achievement of 2014 operational goals of the Chemicals division, for Mr. Breunig, related to ECU reliability and other operational goals, and 2014 operational goals of the Building Products division

for Mr. Orcutt, related to reductions in conversion costs, operating cash flow and the percentage of net sales generated from innovative new products; and

• 20% of the award is based upon the level of achievement of certain 2014 corporate strategic goals.

The objective of providing long-term incentive compensation is to focus executives on increasing shareholder value over a longer period of time. It rewards achievement of the specific metrics described below. We choose to pay long-term incentive compensation because it aligns NEOs’ longer-term interests with those of other stockholders and encourages them to have an ownership mentality. We generally make long-term incentive compensation grants in May of each fiscal year. Historically these grants do not fully vest in less than three years and two-thirds of the total grant would not vest until two years or more after the grant date.

The Company’s 2011 Plan is our long-term incentive plan. The 2011 Plan was approved by our stockholders on May 17, 2011 and amended, with the approval of our stockholders, on January 10, 2013 to:

• increase the total available shares under the 2011 Plan from 1,800,000 to 3,600,000;

• permit the grant under the 2011 Plan of stock-based awards in substitution for or conversion of stock or stock-based awards held by awardees of an entity engaging in a corporate acquisition or merger transaction with the Company or any of its subsidiaries, with the shares of our common stock delivered under the substituted or converted award not counting against the share limit or other limits on the number of shares of our common stock available for issuance under the 2011 Plan; and

• limit the aggregate amount of stock or stock-based awards which a non-employee director may be granted under the 2011 Plan during any calendar year to a value as of their respective dates of grant of $300,000.

The 2011 Plan provides the Committee with an opportunity to make a variety of stock based awards, while selecting the form that is most appropriate for the Company and the executive group. We have historically made the following types of long-term equity awards under the 2011 Plan:

• time-based RSUs that vest ratably over time; and

• performance-based RSUs that vest based solely on the achievement of performance goals or metrics established by the Committee.

In 2013, our NEOs, except for our CEO, received 33% of their long-term incentive compensation in the form of time-based RSUs and 67% in the form of performance-based RSUs with performance criteria generally based on the achievement of annualized synergy targets related to the Company’s merger with the Merged Business. In lieu of time-based RSUs, our CEO received approximately one-third of his long-term equity incentive compensation grants in the form of performance-based RSUs for which the performance criteria was the Company achieving a positive Adjusted EBITDA for the year ended December 31, 2013. In this regard, the Committee concluded that all of the RSUs granted to the CEO should be performance-based, but one-third of those RSUs should be designed primarily to provide an incentive for the CEO to remain with the Company.

In considering the number of time-based RSUs to grant to each of the NEOs, the Committee considered a number of factors, including: (1) the value of long-term incentive grants, including the mix of time-based and performance-based vehicles, in comparable positions at the market reference peer companies described on page 34 of this proxy statement; (2) the number of shares that remained available to be granted under the 2011 Plan; and (3) the financial performance of the Company and the individual performance of each of the NEOs.

In order to award the successful completion of the Company’s merger with the Merged Business, the Committee granted 2,557 time-based RSUs in March

2013 to each of Messrs Thompson, Breunig and Mann, each of whom spent a substantial amount of time evaluating and negotiating the Company’s merger with the Merged Business. The time-based RSUs vest in equal installments on each of the first three anniversaries of the grant date.

The NEOs have no rights of ownership in the shares of our common stock underlying the time-based RSUs and have no right to vote such shares until the applicable vesting date. Dividend equivalents are paid in cash on the shares of our common stock underlying the time-based RSUs and are deferred (with no earnings accruing) until the vesting date.

With respect to the performance-based RSUs granted to the NEOs in May 2013, other than certain performance-based RSUs granted to Mr. Carrico and Mr. Orcutt, the number of shares of our common stock that may be issued to the NEOs upon the vesting of the performance-based RSUs ranges from a minimum of zero to a maximum of 200% of the number of “target” shares awarded, with the actual payout dependent upon the dollar amount of annualized cost synergies achieved in connection with the Merged Business, as determined by the Committee, as of the second anniversary of January 28, 2013, the closing date of the merger with the Merged Business. No performance-based RSUs will be earned if the Company’s Adjusted EBITDA for the period January 1, 2013 through December 31, 2014 does not exceed a specific target. These performance-based RSUs vest 50% on May 2015 and 50% on May 2016, in each case, if each NEO continues to be employed by the Company on the applicable vesting date.

In addition to 46,524 performance-based RSUs conditioned on the achievement of cost synergies, the Committee granted to Mr. Carrico in May 2013, in lieu of time-based RSUs, 23,262 performance-based RSUs conditioned upon the Company achieving positive

Adjusted EBITDA for the year ending December 31, 2013. The Committee determined that this additional condition was appropriate so that all of the RSUs granted to Mr. Carrico would be performance-based, but also so that approximately one-third of Mr. Carrico’s performance-based RSUs would serve primarily as an incentive for Mr. Carrico to remain employed with the Company during that period. The Company satisfied Mr. Carrico’s Adjusted-EBITDA performance targets under these performance-based RSUs by achieving Adjusted EBITDA of $679.1 million for 2013. Accordingly, these performance-based RSUs will vest ratably on each of the first, second and third anniversaries of the grant date.

The Committee also granted Mr. Orcutt performance-based RSUs in May 2013. The number of shares of our common stock that may be issued to Mr. Orcutt upon the vesting of these performance-based RSUs ranges from a minimum of zero to a maximum of 200% of the number of “target” shares awarded, with the actual payout dependent upon the achievement of both: (1) performance targets related to the Adjusted EBITDA of the Building Products division for the period January 1, 2013 through December 31, 2015; and (2) performance targets related to the Adjusted EBITDA

margin (Adjusted EBITDA divided by net sales) of the Building Products division for the period January 1, 2013 through December 31, 2015. Mr. Orcutt’s performance-based RSUs vest on May 20, 2016 if the performance goals have been met and Mr. Orcutt continues to be employed by the Company on that date. The Committee established different performance goals for Mr. Orcutt to properly incent his performance as the most senior officer of the Building Products division, and in recognition of the fact that Mr. Orcutt and the Building Products division would have very limited responsibility, if any, for achieving the cost synergy targets related to the Company’s merger with the Merged Business, which is a chemicals business.

The Committee believes that the performance targets for all of the 2013 performance-based RSUs (other than the CEO’s 2013 performance-based RSUs conditioned upon positive Adjusted EBITDA) have been established at a level that requires superior performance from each of its NEOs.

The Committee determined it was appropriate to grant performance-based RSUs to the NEOs other than Mr. Orcutt, which vest as described above, because the Committee believed:

• Achieving cost synergies in connection with the Company’s merger with the Merged Business is a key strategic objective of the Company given the transformative nature of 2013, and that anticipated synergies achievement was an important factor in the Company’s decision to acquire the Merged Business;
   
• These performance-based RSUs align management’s interests with those of the stockholders and reflect the pay-for-performance component of the Committee’s compensation philosophy, given that the number of shares issuable to the NEOs upon vesting, if any, increases or decreases depending solely on the achievement of such cost synergies; and

• Performance-based RSUs that vest 50% two years after the grant date and 50% three years after the grant date provide an incentive for management continuity and retention over that period, as the Company continues to integrate and further grow the Merged Business.

The Committee determined it was appropriate to grant performance-based RSUs to Mr. Orcutt, which vest as described above, because the Committee believed: (1) improving the financial performance of the Building Products division is a key strategic objective of the Company; (2) these performance-based RSUs align Mr. Orcutt’s interests with those of the stockholders and reflect the pay-for-performance component of the Committee’s compensation philosophy, given that the number of shares issuable to Mr. Orcutt upon vesting, if any, increases or decreases depending solely on the achievement of financial performance goals by the Building Products division; and (3) performance-based RSUs that vest on the third anniversary of the grant date may function as an incentive for Mr. Orcutt to remain with the Company during that period.

In considering the number of performance-based RSUs to grant to each of the NEOs, and in the case of the CEO, to recommend to the independent members of the Board for their ratification following the Committee’s approval, the Committee considered a number of factors, including:

• the value of long-term incentive grants, including the mix of time-based and performance-based vehicles, in comparable positions at the market reference companies described on page 34 of this proxy statement;
   
• the number of shares that remained available to be granted under the Company’s 2011 Plan; and
   
• the financial performance of the Company and the individual performance of each of the NEOs.

In 2011 and 2012, the Committee granted performance-based RSUs, all of which are expected to vest on the third anniversary of the applicable grant date, for which the number of shares issuable on the vesting date, if any, increases and decreases proportionally based solely on the performance of the Company’s stock price, thereby aligning the interests of our NEOs with that of our stockholders. Such RSUs are commonly referred to as “Price Leveraged Units” or “PLUs,” and also may be referred to as “Market Stock Units” or “MSUs,” and are referred to in this Compensation Discussion and Analysis as “PLUs.”

With respect to the PLUs granted to the NEOs in May 2011 and 2012, the number of shares of Company common stock that may be issued to the NEOs upon the vesting of the PLUs ranges from a minimum of zero to a maximum of 150% of the number of “target” shares awarded, with the actual payout dependent solely on the price performance of the Company’s common stock, as measured by the weighted average trading price of the common stock during the 45 consecutive trading days after the date that the Company issues its earnings press release announcing its financial results for its 2013 and 2014 fiscal years, respectively.

The Committee determined it was appropriate to grant PLUs to the NEOs, which vest three years after the grant date, because the Committee believed:

• PLUs align management’s interests with those of the stockholders and reflect the pay-for-performance component of the Committee’s compensation philosophy, given that the number of shares issuable to the NEOs upon vesting, if any, increases or decreases depending solely on the price performance of the Company’s common stock; and

• PLUs that do not vest for three full years after the grant date incent management to focus on maximizing the value of the Company’s stock over the long-term.

Payouts under the PLUs granted in 2011 will not be determined until May 2014 and will be paid at that time. Payouts under the PLUs granted in May 2012 will not be determined until May 2015 and will be paid at that time. We did not grant PLUs to any of our NEOs in 2013.

In March 2014, the Committee determined that the performance metrics for performance-based RSUs granted in 2014 will be based on a relative total shareholder return, defined as share price appreciation and dividends paid, assuming those dividends are reinvested as paid, and these performance-based RSUs will cliff vest on the third anniversary of the grant date if the performance metrics are achieved.

The comparator group will consist of 45 chemical companies from the S&P 1500. The Committee believes that the use of total shareholder return as the relevant performance metric aligns our NEOs’ long-term compensation with the long-term performance of the Company, and accordingly, with the long-term interests of the Company’s shareholders.

The Company does not pay premiums on insurance policies or other products as a supplement to retirement benefits. Rather, the Company has established a Deferred Compensation Plan (the “DCP”) that allows eligible employees, including the NEOs, to elect to defer a portion of their otherwise taxable salary and/or bonus. Under the DCP, the Company also can make two types of credits to such employees’ non-qualified deferred compensation accounts (which are notional accounts). The first type of credit is a matching restoration credit that works in tandem with an eligible employee’s participation in the Company’s 401(k) plan. If an eligible employee elects to contribute to both the 401(k) and the DCP, the Company will restore (or credit) certain employer matching contributions that cannot be made to the 401(k) plan due to the statutory limit on recognized compensation under the terms of the 401(k) plan. The second type of credit is a discretionary Company credit (also referred to as a “Company Benefit”). Amounts deferred by a NEO, and amounts credited by the Company, are shown in the Summary Compensation Table in the year earned or credited, as applicable.

Under the DCP, participants can elect a date for the payout of amounts that they have voluntarily deferred and the “restoration” benefit, which can be during employment or after a separation from service in the form of a lump sum payment or installments with a

duration between two and fifteen years. The Company Benefit is generally paid in a lump sum or in three annual installments commencing upon the later of (i) the first day of the year following the eligible employee’s attainment of age 65; or (ii) the first day of the seventh month following the eligible employee’s separation from service. In addition, the DCP will pay out the balance of a NEO’s account in a lump sum on the thirtieth day after a change of control.

Under the DCP, participants earn a deferred return based (in the case of amounts that they have voluntarily deferred and 401(k) restoration benefits) on deemed investments in mutual funds selected by the participant from a list provided by the Company. In 2013, returns on those deemed investments ranged from about -0.32% to 36.1%. The investment list is similar to the investments available through the Company’s 401(k) Plan. All investment risk is borne by the participant. Gains and losses are credited based on actual market returns earned by the deemed investment and the value of a participant’s account will increase or decrease accordingly.

Company Benefit accounts are credited with a fixed rate of interest equal to the interest crediting factor under the “cash balance” feature of the Company’s qualified retirement plan.

The DCP is intended to comply with the requirements of Section 409A of the Code. Accordingly, deferrals, company contributions and distributions to eligible employees will occur and will be subject to these requirements.

Amounts voluntarily deferred by each of the NEOs in 2013, restoration contributions in 2013, Company Benefit contributions in 2013, earnings on each and year-end account balances for the NEOs are reported under the heading “Executive Compensation-Non-Qualified Deferred Compensation” beginning on page 50.

Our executive officers are eligible to participate in the various benefit plans available to our employees, including those that provide life, health and disability insurance, and access to, and in some instances,

Company contributions into, retirement plans. In addition, in connection with our philosophy to provide only limited perquisites, in 2013, we provided to our executive officers only a Company car or allowance.

The Company entered into a negotiated hiring agreement with Mr. Mann in July 2012. Mr. Mann’s agreement provides for annual base salary (but does not guarantee him any particular dollar amount of base salary beyond his first year of employment), short and long-term incentive compensation opportunities, as well as a car allowance and other benefits. In addition, Mr. Mann’s agreement provides that, if within two years of his first day of employment, his employment is terminated (other than in connection with a change of control, such that he is not entitled to benefits under the Change of Control Plan) involuntarily by the Company

for any reason other than “Cause” (as such term is defined in the Change of Control Plan, but without regard for the fact that a change of control shall not have occurred) or by Mr. Mann for “Good Reason” (as such term is defined in Mr. Mann’s hiring agreement), within thirty days following a “Good Reason event” (as such term is defined in Mr. Mann’s hiring agreement), and subject to Mr. Mann’s execution and non-revocation of a separation agreement and release to be drafted by the Company, the Company will pay to Mr. Mann eighteen months of his annual base salary and bonus target.

In May 2007, the Committee adopted the Change of Control Plan, the terms of which are further described under “Executive Compensation-Payments on Termination or Change of Control.” In addition to supporting key employee retention, the change of control benefits are intended to ensure that executives are able, as a practical matter, to evaluate any potential change of control transaction objectively and to encourage executives to remain employed by the Company in the event a change of control becomes a real possibility. The Change of Control Plan’s benefits were based on typical market practices at what were believed to be no more than median compensation levels when compared to our market references. All of the NEOs participate in the Change of Control Plan.

The Change of Control Plan was amended in May 2011 to eliminate the excise tax gross-up benefit that had been provided under the Change of Control Plan with respect to any person who becomes an executive officer on or after May 16, 2011 (including any person newly hired by the Company and any person promoted from within the Company from a non-executive officer position to an executive officer position on or after that date). For additional information on the Change of Control Plan, see “Payments on Termination of Change of Control — Change of Control Plan.”

On December 9, 2013, the Committee approved and adopted the Severance Plan for certain executive officers and other key employees of the Company, including each of the NEOs. The Severance Plan became effective on January 1, 2014. In addition to attracting and retaining executives and key employees, the Severance Plan benefits are intended to ensure that the Company’s severance-related benefits for executives and key employees are competitive with severance-related benefits offered by other companies with whom the Company may compete for executive-level talent.

The Severance Plan provides for the payment of severance to the NEO if his employment with the Company is terminated without Cause or for Good Reason, each as defined under “Payments on

Termination or Change of Control — Severance Plan.” In the event of such a qualifying termination and subject to the applicable NEO’s execution of a general release of liability against the Company within 45 days after the qualifying termination, the Severance Plan provides that any such NEO is entitled to a severance payment equal to one year’s base salary and target bonus amount, and certain temporary benefits. The Severance Plan does not provide for an excise tax gross-up benefit to any NEOs or other participants to offset any excise taxes that may be imposed on excess parachute payments under Section 4999 of the Code.

For the terms and additional information regarding the Severance Plan, see “Payments on Termination or Change of Control — Severance Plan.”

Certain of the Company’s equity award agreements also provide that unvested equity awards will immediately vest upon a change of control without regard to termination of employment. However, for all equity awards granted to NEOs after May 2011, unvested equity awards will have accelerated vesting upon a change of control only if either: (1) the NEO’s employment is terminated without cause, or the executive officer terminates his employment for good reason, in connection with that change of control; or

(2) the equity award is not assumed or a substitute equity award with equivalent rights is not provided. In other words, for equity awards granted after May 2011, there is a “double trigger” requirement for accelerated vesting. For additional information on potential payments and vesting of equity awards upon termination or a change in control, see “Payments on Termination or Change of Control — Equity Awards” beginning on page 53.

All of our NEOs hired prior to January 1, 2009 are eligible to participate in the Axiall Corporation Retirement Plan (the “Retirement Plan”).

The Retirement Plan is a broadly based, qualified defined benefit pension plan, which provides a benefit upon retirement to eligible Company employees in the United States. In general, all Company employees in the United States who were hired prior to January 1, 2009 are eligible to participate in the Retirement Plan, although benefits may differ for employees covered by collectively bargained agreements or who are working in the operations of an acquired business or were employed prior to 1985 by the Company’s predecessor, Georgia-Pacific Corporation.

The pension benefit is the sum of up to three benefits:

• benefit accruals earned with a predecessor employer (Georgia-Pacific or any acquired company) based on service with the predecessor employer and, in the case of Georgia-Pacific, final average compensation as of the earlier of: (i) the time of termination or retirement, if applicable, or (ii) December 31, 2007. Certain participants in the Retirement Plan who are also participants in the Axiall Corporation 401(k) Plan have sub-accounts, referred to as “Pension Rollover Accounts,” that are part of their 401(k) Plan accounts and that are associated with pre-1985 participation in a Georgia-Pacific defined contribution (savings) plan. Such a participant has the option of receiving the Pension Rollover Account in a lump sum upon retirement. If he or she does so, then the pension benefit under the Retirement Plan is reduced, on an actuarially equivalent basis, to reflect the individual’s receipt of this lump sum amount;

• 1% of aggregate pensionable compensation earned after 1984 and before 2008, which is referred to as a “career average formula.” Pensionable compensation does not include any incentive or deferred compensation;
   
• for employees who actively participated in the Retirement Plan after December 31, 2007, the actuarial equivalent of a notional Cash Balance Account under the Retirement Plan to which are credited (i) specified percentages (ranging from 3.0% for a participant with fewer than 10 years of service and up to 6.0% for a participant with 20 or more years of service) of pensionable compensation, and (ii) interest credits based upon the “30-year Treasury interest rate” as of the last business day of October in the year prior to the year with respect to which the interest credit is made (but not less than 4% interest). As a result of a complete “freeze” on the accrual of additional benefits under the Retirement Plan approved by the Board of Directors in 2009, no additional pay credits are added to the Cash

Balance Accounts with respect to compensation paid after March 31, 2009. However, the interest credits will continue.

As noted above, the Board of Directors approved an amendment to the Retirement Plan to provide for the cessation (or “freezing”) of the accrual of additional benefits under the Retirement Plan, effective as of March 31, 2009.

Normal retirement benefits are available to employees with at least three years of service at age 62 and a reduced pension (by 6% per year prior to age 62) is available as early as age 55. All of the NEOs who participate in the Retirement Plan are fully vested in their benefits. Based on their employment start dates, Messrs. Breunig and Mann are not eligible to participate in the Retirement Plan.

For additional information about the Retirement Plan, including the present value of benefits accrued by each of the NEOs, see “Executive Compensation-Pension Benefits.”

The Company believes that the Company’s compensation and benefit policies and practices are not likely to have a material adverse effect on the Company and that the plans currently in place or contemplated are appropriately balanced between retention and incentive to enable the Company to retain

its management team while providing an incentive for the CEO and other executive officers to be focused on meeting the objectives developed by management and the Board that are designed to create long-term stockholder value.

The Committee has reviewed and discussed the preceding Compensation Discussion and Analysis with management. Based on that review and discussions, the Committee recommended to the Board of Directors that the Compensation Discussion and Analysis be included in the Company’s Annual Report on Form

10-K for the year ended December 31, 2013 and the Company’s proxy statement for the annual meeting of stockholders to be held on May 20, 2014.
