CORPORATE GOVERNANCE HIGHLIGHTS

EXECUTIVE COMPENSATION (PROPOSAL 2)

Performance Highlights in 2016

As described in more detail throughout the "Compensation Discussion and Analysis" beginning on page 24, one of the primary objectives of our executive compensation program is to align our executive officers' pay with our financial performance and the performance of our common stock as measured by total stockholder return ("TSR").

Historically, adjusted EBITDA was the primary financial metric used to measure our executive officers' performance under our annual cash performance award program. In response to feedback from the investment community, we publicly committed to generate free cash flow of $350 million in 2016. In connection with this commitment, we set a goal of improving working capital management by reducing days inventory outstanding ("DIO"). Accordingly, our 2016 annual cash performance award program

​ 2  |  HUNTSMAN 2017 PROXY

​

​

---

Table of Contents

​ ​

included free cash flow and DIO targets, which together accounted for either 35% or 40% of the amount payable to each of our NEOs. Specific achievements in 2016 include the following:

How We Paid for Performance in 2016

Our executive compensation program is designed such that a significant portion of each officer's total target direct compensation is performance-based. On average, 72% of total target direct compensation of our NEOs was at risk, tied to annual performance measures and the performance of our common stock.

Mix of Total Target Direct Compensation in 2016⁽¹⁾

(1)

"Total target direct compensation" consists of (i) annual base salary, (ii) the target annual cash performance award opportunity for 2016, and (iii) the aggregate grant date fair value of long-term equity incentive awards granted in 2016. The amounts actually realized by our NEOs with respect to the annual cash performance awards and long-term equity incentive awards granted in 2016 depend, as applicable, on the level of attainment of the relevant performance goals and the value of our common stock when the awards vest or are exercised.

The greatest driver of the realizable value of compensation for our NEOs is the performance of our common stock price over time. The chart below provides comparisons of the target and realizable values of our CEO's compensation over the last three years as of the end of each year. In 2014 and 2015, when our stock price declined, the realizable value of compensation also declined. In 2016, when we experienced a 73.4% increase in TSR, the realizable value of compensation increased in a corresponding manner.

Realizable pay for each year is defined as the sum of: (1) salary, (2) annual cash performance award payout, and (3) the value of equity incentive awards granted in that year (i.e., performance share units at target, restricted stock units and the "in the money" value of stock options) calculated using our stock price as of the last trading day of each fiscal year.

2014, 2015 and 2016 CEO Aggregate Realizable Pay

Stockholder Outreach and Consideration of our 2016 Say-on-Pay Vote

We maintain regular contact with our external investors regarding our business strategy and our efforts to create long-term value for both our stockholders and debt holders. As discussed above, going into 2016, the investment community had expressed the desire to see free cash flow generation improve. In designing our 2016 cash performance award program, the Compensation Committee took this feedback into consideration in determining to base a portion of our executive officers' compensation under our annual cash performance award program on achievement of free cash flow and DIO performance goals.

At our 2016 annual meeting, 76% of total votes cast (excluding abstentions) voted in favor of our say-on-pay proposal. In designing the executive compensation program for 2017, the Compensation Committee considered the overall support that prior say-on-pay proposal received and decided not to make significant changes to our executive compensation program design. However, the Compensation Committee did make changes to our 2017 peer group or "Proxy Peers," as defined below in "Compensation Discussion and Analysis—How We Determine Executive Compensation—Compensation Benchmarking." The Proxy Peers were modified to exclude some of the larger cap companies against whom we compete and were made partially in response to stockholder feedback and in connection with the transformation of our company as a result of the upcoming spin-off of our Pigments & Additives division.

Overall, we believe our compensation programs are effective in implementing our primary compensation objectives. In the past, based in part on stockholder feedback, the Compensation Committee has made changes to our compensation programs to further strengthen the alignment between our pay and performance. These changes have included the grant of performance share units to our NEOs targeting TSR relative to a group of peers, altering our Executive Chairman's equity-based grants to include performance share units and stock options, changes to the metric weightings of our Executive Chairman's annual cash performance award design and reducing his target and maximum achievable amounts.

PREFERRED FREQUENCY OF EXECUTIVE COMPENSATION ADVISORY VOTES (PROPOSAL 3)

We believe that say-on-pay votes should be conducted every year so that stockholders may provide us with direct and timely input on our executive compensation program. While our executive compensation programs are designed to promote a long-term connection between pay and performance, the Board recognizes that executive compensation disclosures are made annually and holding an annual advisory vote on executive compensation provides us with more direct and immediate feedback on our compensation disclosures. However, stockholders should note that because the advisory vote on executive compensation occurs well after the beginning of the compensation year, and because the different elements of our executive compensation programs are designed to operate in an integrated manner and to complement one another, in many cases it may not be appropriate or feasible to change our executive compensation programs in consideration of any one year's advisory vote on executive compensation by the time of the following year's annual meeting of stockholders.

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (PROPOSAL 4)

We ask that our stockholders ratify the selection of Deloitte & Touche LLP as our independent registered public accounting firm for 2017.

HUNTSMAN CORPORATION : PROXY STATEMENT

GENERAL

This Proxy Statement is being furnished to the stockholders of Huntsman Corporation (the "Company") in connection with the solicitation of proxies by its Board of Directors (the "Board"). The proxies are to be voted at our 2017 Annual Meeting of Stockholders (the "Annual Meeting") to be held at The Westin The Woodlands, 2 Waterway Square Place, The Woodlands, Texas 77380, at 8:30 a.m., local time, on May 4, 2017, and any adjournments or postponements thereof, for the purposes set forth in the accompanying Notice of Annual Meeting. The Board is not aware of any other matters to be presented at the Annual Meeting.

The Board is soliciting your proxy to vote your shares at the Annual Meeting. We will bear the cost of the solicitation, including the cost of the preparation, assembly, printing and, where applicable, mailing of the Notice of Annual Meeting of Stockholders, this Proxy Statement, the proxy card, the Notice of Internet Availability of Proxy Materials (the "Notice of Internet Availability") and any additional information furnished by us to our stockholders. In addition to solicitation by mail, certain of our directors, officers and employees may, without extra compensation, solicit proxies by telephone, facsimile, electronic means and personal interview. We have retained D.F. King & Co., Inc. to help us distribute and solicit proxies and have agreed to pay them $14,000, plus reimbursement for out-of-pocket expenses, for these services. We will also make arrangements with brokerage houses, custodians, nominees and other fiduciaries to send proxy materials to their principals, and we will reimburse them for postage and clerical expenses.

DELIVERY OF PROXY MATERIALS

On or about March 23, 2017, we mailed a Notice of Internet Availability to our stockholders of record and beneficial owners who owned shares of our common stock at the close of business on March 10, 2017. The Notice of Internet Availability contained instructions on how to access the proxy materials and vote online. We have made these proxy materials available to you over the Internet or, upon your request, have delivered paper versions of these materials to you by mail, in connection with the solicitation of proxies by our Board for the Annual Meeting.

Choosing to receive your future proxy materials by e-mail will save us the cost of printing and mailing documents to you. If you choose to receive future proxy materials by e-mail, you will receive an e-mail next year with instructions containing a link to those materials and a link to the proxy voting site. Your election to receive proxy materials by e-mail will remain in effect until you terminate it.

3. WHAT IS A PROXY?

A proxy is your legal designation of another person to vote the stock you own. That other person is called a proxy. If you designate someone as your proxy in a written document, that document also is called a proxy or a proxy card. Peter R. Huntsman, our President and Chief Executive Officer, also referred to herein as our "CEO," and David M. Stryker, our Executive Vice President, General Counsel, Chief Compliance Officer and Secretary, will serve as proxies for the Annual Meeting pursuant to the proxy card solicited by our Board.

4. WHAT IS A PROXY STATEMENT?

A proxy statement is a document that the regulations of the U.S. Securities and Exchange Commission (the "SEC") require us to give you when we ask that you designate Peter R. Huntsman and David M. Stryker as proxies to vote on your behalf. This Proxy Statement includes information about the proposals to be considered at the Annual Meeting and other required disclosures, including information about the Board and our executive officers.

5. HOW CAN I ACCESS THE PROXY MATERIALS OVER THE INTERNET?

If you choose to access future proxy materials electronically, you will receive an e-mail with instructions containing a link to the website where those materials are available and a link to the proxy voting website. Your election to access proxy materials by e-mail will remain in effect until you terminate it.

6. WHAT IS THE RECORD DATE AND WHAT DOES IT MEAN?

The record date for the Annual Meeting is March 10, 2017. Owners of record of our common stock at the close of business on the record date are entitled to:

•

receive notice of the Annual Meeting; and

•

vote at the Annual Meeting and any adjournments or postponements in accordance with our Bylaws.

7. WHO MAY ATTEND THE ANNUAL MEETING?

All stockholders of record who owned shares of common stock at the close of business on March 10, 2017, or their duly appointed proxies, may attend the Annual Meeting and any adjournments or postponements thereof, as may our invited guests. "Street name stockholders," as described in Question 9 below, who owned shares of common stock at the close of business on March 10, 2017, may also attend subject to the requirements set forth in Questions 9 and 10 below. Seating is limited and admission is on a first-come, first-served basis. If you attend the Annual Meeting, you will need to bring your Notice of Internet Availability or proxy card, as applicable, a form of personal identification (such as a driver's license) and check in at the registration desk at the Annual Meeting. Please note that if you hold shares in "street name" (that is, in a brokerage account or through a bank or other nominee), you also will need to bring a copy of a statement reflecting your share ownership as of March 10, 2017.

8. HOW MANY VOTES ARE REQUIRED TO HOLD THE ANNUAL MEETING?

The required quorum for the transaction of business at the Annual Meeting is a majority of all outstanding shares of our common stock entitled to vote in the election of directors at the Annual Meeting, represented in person or by proxy. Consequently, the presence, in person or by proxy, of the holders of at least 119,811,964 shares of our common stock is

​ 6  |  HUNTSMAN 2017 PROXY

​

​

---

Table of Contents

​ ​

required to establish a quorum at the Annual Meeting. Shares that are voted with respect to a particular matter are treated as being present at the Annual Meeting for purposes of establishing a quorum.

9. WHAT IS THE DIFFERENCE BETWEEN A STOCKHOLDER OF RECORD AND A STOCKHOLDER WHO HOLDS STOCK IN STREET NAME?

Most stockholders hold their shares through a broker, bank or other nominee (i.e., in "street name") rather than directly in their own name. As summarized below, there are some distinctions between shares held of record and those held in street name.

•

Stockholders of Record.  If your shares are registered directly in your name with our transfer agent, you are considered, with respect to those shares, the "stockholder of record." As the stockholder of record, you have the right to grant your voting proxy directly or to vote in person at the Annual Meeting.

•

Street Name Stockholders.  If your shares are held in a stock brokerage account or by a bank or other nominee, you are considered, with respect to those shares, the beneficial owner of shares held in "street name," and the Notice of Internet Availability or proxy materials are being forwarded to you by your broker, bank or other nominee, which is considered, with respect to those shares, the stockholder of record. As the beneficial owner, you have the right to instruct your broker, bank or other nominee how to vote and you are also invited to attend the Annual Meeting. However, since you are not the stockholder of record, you may not vote these shares in person at the Annual Meeting unless you obtain a signed proxy from the stockholder of record giving you the right to vote the shares. Your broker, bank or other or nominee has provided voting instructions for you to use in directing the broker, bank or other or nominee how to vote your shares. If you fail to provide sufficient instructions to your broker, bank or other nominee or nominee, they may be prohibited from voting your shares. See "If I am a street name holder, will my shares be voted if I do not provide my proxy?"

10. WHAT DIFFERENT METHODS CAN I USE TO VOTE?

Stockholders of Record:    Stockholders of record may (1) vote their shares in person at the Annual Meeting by completing a ballot; or (2) submit a proxy to have their shares voted by one of the following methods:

•

By Internet.    You may submit a proxy electronically on the Internet by following the instructions provided on the proxy card or Notice of Internet Availability. Please have your proxy card or Notice of Internet Availability in hand when you log onto the website. Internet voting facilities will be available 24 hours a day and will close at 11:59 p.m., Eastern Daylight Time, on May 3, 2017.

•

By Telephone.    You may submit a proxy by telephone (from U.S. and Canada only) using the toll-free number listed on the proxy card or Notice of Internet Availability. Please have your proxy card or Notice of Internet Availability in hand when you call. Telephone voting facilities will be available 24 hours a day and will close at 11:59 p.m., Eastern Daylight Time, on May 3, 2017.

•

By Mail.    If you received a paper copy of the proxy materials by mail, you may indicate your vote by completing, signing and dating your proxy card and returning it in the enclosed reply envelope.

Street Name Stockholders:    Street name stockholders may generally vote their shares or submit a proxy to have their shares voted by one of the following methods:

•

By the Methods Listed on the Voting Instruction Form.    Please refer to the voting instruction form or other information forwarded by your bank, broker or other nominee to determine whether you may submit a proxy by telephone or on the Internet, following the instructions provided by the record holder.

•

In Person with a Proxy from the Record Holder.    You may vote in person at the Annual Meeting if you obtain a legal proxy from your bank, broker or other nominee. Please consult the voting instruction form or other information sent to you by your bank, broker or other nominee to determine how to obtain a legal proxy in order to vote in person at the Annual Meeting.

If you hold shares in BOTH street name and as a stockholder of record, YOU MUST VOTE SEPARATELY for each set of shares.

EVEN IF YOU PLAN TO ATTEND THE ANNUAL MEETING, WE RECOMMEND YOU ALSO SUBMIT YOUR PROXY SO THAT YOUR VOTE WILL COUNT IF YOU ARE UNABLE TO ATTEND THE MEETING. SUBMITTING YOUR PROXY VIA INTERNET, TELEPHONE OR MAIL DOES NOT AFFECT YOUR ABILITY TO VOTE IN PERSON AT THE ANNUAL MEETING.

​ ​

11. WHAT IF I AM A STOCKHOLDER OF RECORD AND I DON'T SPECIFY A CHOICE FOR A MATTER WHEN RETURNING MY PROXY?

A proxy that is properly completed and submitted will be voted at the Annual Meeting in accordance with the instructions on the proxy. If you properly complete and submit a proxy, but do not indicate any contrary voting instructions, your shares will be voted as follows:

•

FOR the election of the eight director nominees named in this Proxy Statement;

•

FOR approval, on a non-binding advisory basis, of the compensation of our NEOs;

•

1 YEAR for the preferred frequency, on a non-binding advisory basis, of advisory votes on the compensation of our NEOs; and

•

FOR the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the year ending December 31, 2017.

If any other business properly comes before the stockholders for a vote at the meeting, your shares will be voted at the discretion of the holders of the proxy. The Board knows of no matters, other than those previously described, to be presented for consideration at the Annual Meeting.

12. IF I AM A STREET NAME STOCKHOLDER, WILL MY SHARES BE VOTED IF I DO NOT PROVIDE MY PROXY?

In some cases, your shares may be voted if they are held in the name of a brokerage firm, even if you do not provide the brokerage firm with voting instructions. Specifically, brokerage firms have the authority under New York Stock Exchange ("NYSE") rules to cast votes on certain "routine" matters if they do not receive instructions from the beneficial holder. For example, ratification of the appointment of the independent registered public accounting firms is considered a routine matter for which a brokerage firm may vote shares for which it has not received voting instructions. This is called a "broker discretionary vote." When a proposal is not a routine matter and a brokerage firm has not received voting instructions from the beneficial owner of the shares with respect to that proposal, the brokerage firm cannot vote the shares on that proposal. This is called a "broker non-vote." The election of directors, the advisory vote to approve NEO compensation and the advisory vote on the preferred frequency of advisory NEO compensation votes are not considered routine matters. Therefore, if you are a street name stockholder and do not provide voting instructions to your broker with respect to these matters, it will result in a broker non-vote with respect to such proposals. Broker non-votes will have no effect on the outcome of these proposals.

13. WHAT VOTES ARE NEEDED FOR EACH PROPOSAL TO PASS AND IS BROKER DISCRETIONARY VOTING ALLOWED?

​ ​

14. WHAT HAPPENS IF ADDITIONAL PROPOSALS ARE PRESENTED AT THE ANNUAL MEETING?

If you grant a proxy, the persons named as proxy holders will have discretion to vote your shares on any additional matters properly presented for a vote at the Annual Meeting. Under Rule 14a-8 and the provisions of our Bylaws, the deadline for notifying us of any additional proposals to be presented at the Annual Meeting has passed and, accordingly, stockholders may not present proposals at the Annual Meeting.

15. CAN I CHANGE MY VOTE AFTER SUBMITTING MY PROXY?

If you are a stockholder of record, you may revoke a previously submitted proxy at any time before the polls close at the Annual Meeting by:

•

voting again by telephone or through the Internet prior to 11:59 p.m. Eastern Daylight Time on May 3, 2017;

•

requesting, completing and mailing in a new paper proxy card, as outlined in the Notice of Internet Availability;

•

giving written notice of revocation to our Corporate Secretary by mail to Corporate Secretary, 10003 Woodloch Forest Drive, The Woodlands, Texas 77380 or by facsimile at (281) 719-4500; or

•

attending the Annual Meeting and voting in person.

If you are a street name stockholder, you must follow the instructions to revoke your proxy, if any, provided by your bank, broker or other nominee.

16. WHAT DOES IT MEAN IF I RECEIVE MORE THAN ONE NOTICE OF INTERNET AVAILABILITY OR MORE THAN ONE SET OF PROXY MATERIALS?

It means that you have multiple accounts with our transfer agent, Computershare, and/or brokers, banks or other nominees. Please vote all of your shares. We recommend that you contact Computershare and/or your broker, bank or other nominee (as applicable) to consolidate as many accounts as possible under the same name and address. If you have multiple accounts with Computershare that you want to consolidate, please submit your request by mail to Computershare Trust Company, N.A., P.O. Box 30170, College Station, TX, 77842, or by telephone at 1-866-210-6997. Computershare may also be reached through its website at www.computershare.com.

DIRECTOR NOMINEES

Presented below is information with respect to our eight director nominees to be elected as directors at this year's Annual Meeting. In 2014, we amended our Certificate of Incorporation to provide that director nominees are elected to serve one year terms, which has resulted in our Board being fully declassified beginning in 2017. The information presented below for each director includes the specific experience, qualifications, attributes and skills that led us to the conclusion that such director should serve on the Board.

NOMINEES TO BE ELECTED AT THE ANNUAL MEETING (TERMS WILL EXPIRE IN 2018)

Jon M. Huntsman, age 79, is the Executive Chairman of the Board, also referred to herein as our "Executive Chairman."

Mr. Huntsman served as Chief Executive Officer of our company and our affiliated companies from 1970 to 2000. Mr. Huntsman is a director or manager, as applicable, of Huntsman International and certain of our other subsidiaries. In addition, Mr. Huntsman serves or has served as Chairman or as a member of numerous corporate, philanthropic and industry boards, including the American Red Cross, The Wharton School, University of Pennsylvania, Primary Children's Medical Center Foundation, the Chemical Manufacturers Association and the American Plastics Council.

The Board has concluded that Mr. Huntsman should continue to serve as the Executive Chairman for the following reasons, among others: (1) his vital role in the founding and history of our company enables him to provide the Board with important perspective and extensive knowledge of our business; (2) his extensive experience in the chemical industry allows him to advise the Board on our strategic and operational directives; and (3) his leadership and business skills enable him to lead our company and the Board as well as continually educate and advise the Board on our company's industry and related opportunities, issues, and challenges.

Peter R. Huntsman, age 54, has served as a director of our company and affiliated companies since 1994. Mr. Huntsman is President, Chief Executive Officer and a director of our company. Prior to his appointment in July 2000 as CEO, Mr. Huntsman had served as President and Chief Operating Officer since 1994. In 1987, after working for Olympus Oil since 1983, Mr. Huntsman joined Huntsman Polypropylene Corporation as Vice President before serving as Senior Vice President and General Manager.

The Board has concluded that Mr. Archibald should continue to serve as the Vice Chairman and Lead Independent Director of the Board for the following reasons, among others: (1) his extensive executive-level management experience gained with Stanley Black & Decker has given him leadership and business capabilities that provide the Board with a unique skill set and significant business and strategic insight; and (2) his extensive board experience as a director of other public companies enables him to contribute significantly to the Board's oversight responsibilities.

Dr. Beckerle, age 62, has served as a director since May 2011. She serves as a member of the Audit Committee and the Governance Committee.

The Board has concluded that Dr. Beckerle should continue to serve as a director for the following reasons, among others: (1) her achievements and credentials in science and medical research enable her to provide the Board with a unique perspective and technical insights relevant to the chemical industry; (2) her international experience allows her to provide insights into challenges and opportunities related to our global business; (3) her extensive leadership, organizational planning, and management credentials enable her to offer practical insight with respect to our company's operational and strategic initiatives; and (4) her academic and public policy experience provides a valuable perspective in areas related to corporate governance, compliance and talent management.

Prior to joining Ryder, Mr. Burns served in management of Mobil Oil Corporation. He is a Life Trustee of the University of Miami in Florida and is active in cultural and civic organizations in Florida.

The Board has concluded that Mr. Burns should continue to serve as a director for the following reasons, among others: (1) his long tenure as Chief Executive Officer of Ryder System, a major public company, provides the Board with valuable leadership and management insights; (2) his prior service on (and in some cases chairmanship of) the audit committees of other public companies has provided him with valuable financial expertise and enhances his ability to serve as chair of our Audit Committee; and (3) his executive compensation experience through prior service on the compensation committees of other public companies has provided him with exposure to, and insight from, CEOs and boards of other large companies.

DIRECTOR COMPENSATION

Our Corporate Governance Guidelines provide for compensation for our non-employee directors' services, in recognition of their time and skills. Annual compensation for our non-employee directors is composed of cash and stock-based equity compensation. Directors who are also our officers or employees do not receive additional compensation for serving on the Board. Cash compensation paid to our non-employee directors consists of an annual retainer (which for 2016 remained at the same level as in effect since 2012) and a supplemental retainer for the chairs and members of Board committees (which for 2016 remained at the same levels as in effect since 2009 and which are detailed in footnote (3) to the Director Compensation Table below). Stock-based equity compensation for 2016 consisted of awards granted under the Huntsman Corporation Stock Incentive Plan as amended and restated effective May 8, 2014 (the "Prior Stock Incentive Plan") in the form of stock or stock units, at the election of each director.

Maintaining a market-based compensation program for our non-employee directors enables our company to attract qualified members to serve on the Board. With the assistance Meridian Compensation Partners, LLC ("Meridian"), the Compensation Committee's independent compensation consultant, the Compensation Committee periodically reviews our non-employee director compensation practices and compares them to the practices of our peers as well as against the practices of public company boards generally to ensure they are aligned with market practices.

We also offer non-employee directors the opportunity to participate in the Huntsman Outside Directors Elective Deferral Plan. This is an unfunded nonqualified deferred compensation plan established primarily for the purpose of providing our non-employee directors with the ability to defer the receipt of director fees. For 2016, Dr. Beckerle was the only non-employee director who elected to participate in this plan, and she elected to defer all 2016 fees. The investment choices available under this plan are identical to the investment choices available under our 401(k) plan, which are described in greater detail below under "Compensation Discussion and Analysis—Elements of Huntsman's Executive Compensation Program—Other Elements of Compensation." Benefits under the plan are payable in cash distributable either in a lump sum or in installments beginning 30 days after the director ceases to be a member of our Board.

Members of the Board may also participate in the Huntsman Director Matching Gift Program. Designed to demonstrate our commitment to worthy causes and to attract talented directors, our company will match charitable contributions made in cash up to a maximum of $10,000 per director per year for organizations located in the United States that are tax exempt pursuant to Section 501(c)(3) of the Internal Revenue Code.

The Compensation Committee believes that our total director compensation package is competitive with the compensation offered by other companies and is fair and appropriate in light of the responsibilities and obligations of our non-employee directors. Details of our non-employee director compensation program are below.

DIRECTOR COMPENSATION TABLE

The total 2016 compensation for our non-employee directors is shown in the following table:

The Board is committed to corporate governance principles and practices that facilitate the fulfillment of its fiduciary duties to stockholders and to our company. Key corporate governance principles observed by the Board and our company include:

BOARD GOVERNANCE

The Board and its committees meet throughout the year on a set schedule, and also hold special meetings and act by written consent from time to time as appropriate. During 2016, the Board met eight times, the non-management directors met in executive session four times and the independent directors met in executive session four times. During 2016, each director attended at least 75% of the aggregate of:

•

the total number of meetings of the Board; and

•

the total number of meetings held by all Board committees on which such person served.

BOARD LEADERSHIP STRUCTURE AND EXECUTIVE SESSIONS OF THE BOARD

According to our Bylaws, the Chairman of the Board is elected by all of the directors on the Board to preside at all meetings of the Board and stockholders. The Chairman of the Board is also required to make reports to the Board and the stockholders and to ensure that all orders and resolutions of the Board and any of its committees are carried into effect. Our Bylaws also allow the Board to elect an Executive Chairman. If elected, the Executive Chairman fills the role of Chairman of the Board and has other powers and duties including, among others, consulting on the strategic vision of our company, promoting Huntsman's interests through his influence and global ties and serving as a facilitator for communication between our officers and the Board. In accordance with our Corporate Governance Guidelines, the Executive Chairman is also responsible for establishing the agenda for each Board meeting. At the beginning of the year, the Executive Chairman establishes a schedule of agenda

​

​

​ 15  |  HUNTSMAN 2017 PROXY

---

Table of Contents

​ ​

subjects to be discussed during the year (to the degree this can be foreseen). Each Board member is also free to suggest the inclusion of additional items on the agenda and to raise subjects at any Board meeting that are not on the agenda for that meeting. Jon M. Huntsman is currently the Executive Chairman. As such, he also fills the role of Chairman of the Board.

In accordance with our Corporate Governance Guidelines, the Board has no policy with respect to the separation of the offices of Chairman of the Board and Chief Executive Officer. Our Bylaws expressly allow our Chairman of the Board to also serve as President or Chief Executive Officer, if so elected by the Board. Currently, the Chairman of the Board does not serve as President or Chief Executive Officer. The Board believes that this issue should be considered periodically as part of the succession planning process and that it is in the best interests of our company for the Board to make a determination regarding this issue each time it appoints a new Chief Executive Officer. Based on these principles, the Board may determine that it is appropriate in the future to combine the roles of Chairman of the Board and Chief Executive Officer.

Our Bylaws also allow the Board to elect one or more Vice Chairmen to preside at Board and stockholder meetings and to perform such other duties as may be delegated by the Board, in either case in the absence of Chairman of the Board. The Board believes that it obtains effective additional Board leadership through the role of the Vice Chairman, which is currently filled by Mr. Archibald, who also serves as Lead Independent Director. As Lead Independent Director, Mr. Archibald communicates with management on issues relevant to the independent directors and provides leadership on matters where management may have a conflict of interest. In accordance with our Corporate Governance Guidelines, non-management directors meet in executive session without management at each regularly scheduled Board meeting, or more frequently as needed at the call of one or more of our non-management directors. Our Corporate Governance Guidelines also require that our independent directors meet in executive session at least once annually without those non-management directors who are not independent, or more frequently as needed at the call of one or more of our independent directors. Mr. Archibald, who serves as Vice Chairman of the Board and Lead Independent Director, chairs these sessions.

We believe that the appropriate Board leadership structure for our company varies depending on the circumstances facing the Board and our company at any given time. For example, we have revised the Board's leadership structure in the past to address specific needs, such as the formation of a Litigation Committee (in November 2008) and the change of Jon M. Huntsman's role from Chairman to Executive Chairman (in February 2009) in recognition of his ongoing strategic leadership at both a Board and an executive level. We believe that our current Board leadership structure efficiently addresses our company's present needs and allows the Board to fulfill its role in exercising effective, independent oversight of our management on behalf of our stockholders. The Board further believes that we have in place effective structures, processes and arrangements to ensure that the work of the Board is completed in a manner that maintains the highest standards of corporate governance, independence and leadership, as well as continued accountability of management.

BOARD INDEPENDENCE

It is important to our company that investors have confidence that the individuals serving as independent directors on the Board do not have relationships with us that impair their independence. Under NYSE corporate governance rules, the Board must have a majority of independent directors. For a director to qualify as independent, the Board must affirmatively determine that the director has no material relationship with our company, either directly or as a partner, stockholder or officer of an organization that has a relationship with our company. To assist in making independence determinations, the Board has adopted independence criteria which can be found on our website at www.huntsman.com. Under these criteria, a director is not independent if:

•

The director is, or has been within the last three years, an employee of our company or an employee of any of our subsidiaries, or an immediate family member is, or has been within the last three years, an executive officer of our company.

•

The director has received, or has an immediate family member who has received, during any twelve-month period within the last three years, more than $120,000 in direct compensation from us (other than director and committee fees and pension or other forms of deferred compensation for prior service, which compensation is not contingent upon continued service). Compensation received by an immediate family member for service as an employee (other than an executive officer) of ours is not considered for purposes of this standard.

•

The (1) director or an immediate family member is a current partner of a firm that is our internal or external auditor; (2) director is a current employee of such a firm; (3) director has an immediate family member who is a current employee of such a firm and who personally works on our company's audit; or (4) director or an immediate family member was within the last three years a partner or employee of such a firm and personally worked on our audit within that time

Table of Contents

​ ​

•

The director or an immediate family member is, or has been within the last three years, employed as an executive officer of another company where any of our present executive officers at the same time serves or served on that company's compensation committee.

•

The director is a current employee, or an immediate family member of the director is a current executive officer, of a company that has made payments to, or received payments from, us for property or services in an amount which, in any of the last three fiscal years, exceeds the greater of $1.0 million or 2% of such other company's consolidated gross revenues.

•

The director is an executive officer of any charitable or non-profit organization to which we have made, within the preceding three years, contributions in any single fiscal year that exceeded the greater of $1.0 million, or 2% of such charitable or non-profit organization's consolidated gross revenues.

With the assistance of company legal counsel, the Governance Committee has reviewed the applicable legal and NYSE standards for independence, as well as our independence criteria. Each year, the Governance Committee reviews: (i) a summary of the answers to annual questionnaires completed by each of the directors (and, if applicable, any nominees for director); and (ii) to the extent applicable, a report of transactions and relationships between each director (and, if applicable, any nominee for director) or any of such director's family members, and our company, our senior management or our independent registered public accounting firm. To the extent that such relationships do not change from year to year, the Governance Committee is informed that there have been no changes such relationships.

In conducting its independence review, the Governance Committee specifically considered the relationships discussed under "Additional Information—Certain Relationships and Related Transactions—Transactions" other than the compensation arrangements, which are reviewed by the Compensation Committee. In addition, the Governance Committee has considered Dr. Beckerle's position as CEO of the Huntsman Cancer Institute, or the Institute. The Governance Committee took into account the fact that Jon M. Huntsman has no ownership of the Institute, which is part of the University of Utah, a public institution owned by the State of Utah. The Governance Committee further considered that beginning a number of years ago, the Huntsman Cancer Foundation, a 501(c)(3) charity whose purpose is to help fund the Institute, has made stipend payments of $100,000 annually to the CEO of the Institute. The Governance Committee took into account that Jon M. Huntsman serves as Chairman Emeritus of the Huntsman Cancer Foundation, and that our company has no financial relationship with either the Huntsman Cancer Foundation or the Institute other than purchasing seats at a table for $10,000 at an annual fundraiser for the Institute.

On the basis of its review, the Governance Committee delivered a report to the full Board, and the Board made its independence determinations based on the Governance Committee's report and the supporting information. As a result of this review, the Board has determined that Messrs. Archibald, Burns, Reaud, Shoemaker, Sir Robert and Dr. Beckerle, who currently constitute a majority of the Board, are independent. These independent directors currently comprise, in full, the membership of the Audit, Compensation and Governance committees of the Board discussed below.

Jon M. Huntsman is not considered to be an independent director because he is employed by our company and is the father of Peter R. Huntsman, our CEO. Peter R. Huntsman is not considered to be an independent director because he is employed by our company and is the son of Jon M. Huntsman, our Executive Chairman.

COMMITTEES OF THE BOARD

The Board has Audit, Compensation and Governance committees, each consisting of independent directors and structured as follows:

Each of these committees has a written charter approved by the Board. These charters are available on our website at www.huntsman.com. We will also furnish copies of the charters free of charge to any person who requests them. Requests for copies should be directed to the Corporate Secretary, 10003 Woodloch Forest Drive, The Woodlands, Texas 77380 or to CorporateSecretary@huntsman.com.

AUDIT COMMITTEE

Duties

Under the independence criteria that the Board has adopted, which can be found on our website at www.huntsman.com, a member of the Audit Committee will not be considered independent if:

•

The member receives directly or indirectly any consulting, advisory or other compensatory fee from us (other than director and committee fees and pension or other forms of deferred compensation for prior service, which compensation is not contingent upon continued service);

•

An immediate family member of the member receives any consulting, advisory or other compensatory fee from us (other than director and committee fees and pension or other forms of deferred compensation for prior service, which compensation is not contingent upon continued service);

​ ​

•

An entity in which the member is a partner, member, an officer such as a managing director occupying a comparable position or executive officer, or occupies a similar position (except limited partners, non-managing members and those occupying similar positions, who, in each case, have no active role in providing services to the entity) and which provides accounting, consulting, legal, investment banking or financial advisory services to us receives any consulting, advisory or other compensatory fee from us; or

•

The member is otherwise an affiliated person of our company.

Furthermore, under these independence standards, (1) each member of the Audit Committee must be financially literate, (2) at least one member of the Audit Committee must have accounting or related financial management expertise and qualify as an "audit committee financial expert" and (3) no member of the Audit Committee may simultaneously serve on the audit committees of more than two other public companies. For purposes of (2) above, the Board considers any Audit Committee member who satisfies the SEC's definition of "audit committee financial expert" to have accounting or related financial management expertise.

The Board has determined that each member of the Audit Committee is independent as that term is defined by the listing standards of the NYSE and Rule 10A-3 promulgated under the Securities Exchange Act of 1934 and satisfies the additional independence criteria adopted by the Board and described above. The Board has also determined that each member of the Audit Committee, qualifies as an "audit committee financial expert" as defined by the regulations of the SEC. No member of the Audit Committee serves on more than two other public company audit committees.

COMPENSATION COMMITTEE

Duties

*

Please see "Compensation Discussion and Analysis—How We Determine Executive Compensation" for additional information on the Compensation Committee's processes and procedures for the consideration and determination of executive officer and director compensation.

The Compensation Committee's charter permits the Compensation Committee to form and delegate some or all of its authority to subcommittees when it deems appropriate. In particular, the Compensation Committee may delegate the approval of both cash and equity award grants and other responsibilities regarding the administration of compensatory programs to a subcommittee consisting solely of members of the Compensation Committee who are non-employee directors or outside directors, or in some limited circumstances, to management.

The Compensation Committee typically meets at least four times each year to address various compensation issues and processes. Our CEO does not have the ability to call Compensation Committee meetings, but generally attends Compensation Committee meetings at the Compensation Committee's request to answer questions and provide input regarding the performance of our executive officers. However, the CEO is not present while decisions regarding his compensation are made. In addition, each Compensation Committee meeting includes an executive session without members of management present. The Compensation Committee regularly reports to the full Board regarding executive compensation matters.

NOMINATING AND CORPORATE GOVERNANCE COMMITTEE

Duties

LITIGATION COMMITTEE

In addition to the independent committees described above, the Board also has a Litigation Committee. The Litigation Committee assists the Board by reviewing and assessing current and potential litigation and areas of legal exposure in which our company is or could be involved and making recommendations to the Board regarding legal matters. The members of the Litigation Committee are Wayne A. Reaud, who serves as the committee's Chair, Jon M. Huntsman and Peter R. Huntsman. The Litigation Committee generally meets quarterly in connection with our regularly scheduled Board meetings.

BOARD ROLE IN RISK OVERSIGHT

It is management's responsibility to assess and manage the various risks our company faces. It is the Board's responsibility to oversee management in this effort. The Audit Committee is responsible for administering the Board's oversight function, and seeks to understand our company's risk philosophy by having discussions with management to establish a mutual understanding of our company's overall appetite for risk. In exercising its oversight, the Audit Committee strives to effectively oversee our company's enterprise-wide and financial risk management in a way that balances managing risks while enhancing the long-term value of our company for the benefit of our stockholders. The Board understands that its focus on effective risk oversight is critical to setting our company's tone and culture towards effective risk management.

The Audit Committee maintains an active dialogue with management about existing risk management processes and how management identifies, assesses and manages our company's most significant risk exposures. The Audit Committee receives regular presentations from management of our businesses and functions about significant risks the respective business or function faces to assist the Audit Committee in evaluating Huntsman's risk assessment and risk management policies and practices.

In addition, each of our other committees assesses risks related to such committee's oversight activities. For example, our Litigation Committee assesses risk from litigation and areas of legal exposure to which our company is or could be subject and makes recommendations to the Board regarding those matters. We believe that the oversight function of the Board and these committees combined with its active dialogue with management about effective risk management provides our company with the appropriate framework to help ensure effective risk oversight.

DIRECTOR ATTENDANCE AT THE ANNUAL MEETING OF STOCKHOLDERS

We believe that there are benefits to having members of the Board attend our annual meetings of stockholders. From time to time, however, a member of the Board might have a compelling and legitimate reason for not attending an annual meeting. As a result, the Board has decided that director attendance at our annual meetings of stockholders should be strongly encouraged, but not required. All of our directors attended the 2016 annual meeting in person.

DIRECTOR QUALIFICATION STANDARDS AND DIVERSITY

The Governance Committee's minimum qualifications and specific qualities and skills required for directors are set forth in Section 1 of our Corporate Governance Guidelines, which are available on our website at www.huntsman.com. These Guidelines require that a majority of directors on the Board meet the criteria for independence required by the NYSE, and that each director functions consistent with the highest level of professional ethics and integrity. Each of our directors is expected to devote sufficient time and effort to learn the business of our company and the Board, to use his or her own unique skills and experiences to provide independent oversight to our business, to participate in a constructive and collegial manner, to exhibit a high level of commitment to our company and to exhibit independent thought and judgment. Although we do not have a separate diversity policy relating to the identification and evaluation of nominees for director, our Corporate Governance Guidelines require that the Governance Committee consider each candidate's background, ability, judgment, skills and experience in the context of the needs of the Board when evaluating director nominees. The Governance Committee believes it is important for Board members to possess skills and knowledge in the areas of leadership of large, complex organizations, finance, strategic planning, legal, government relations and relevant industries, especially the chemical industry. These considerations help the Board as a whole to have the appropriate mix of characteristics, skills and experiences for optimal functioning in its oversight of our company. As part of its periodic self-assessment process, the Governance Committee annually reviews and evaluates its performance, including the overall composition of the Board and the criteria that it uses for selecting nominees.

DIRECTOR NOMINATION PROCESS

The Governance Committee identifies director candidates through a variety of means, including recommendations from other Board members and management. From time to time, the Governance Committee may use third-party search consultants to identify director candidates. The Governance Committee also welcomes stockholder recommendations for candidates for the Board. All stockholder recommendations must comply with the notice requirements contained in Section 2.8 of our Bylaws, which require, among other things, detailed information concerning the stockholder making the proposal (and the beneficial owner on whose behalf the proposal is made, if any), the name and address of the stockholder and specific information concerning such stockholder's interests in our company's securities, including derivative instruments. In addition, the notice must include the recommended candidate's name, biographical data, qualifications, details regarding any material monetary agreements between the stockholder and the proposed nominee, and a written questionnaire completed by the proposed nominee.

In December 2016, our Bylaws were amended to allow eligible stockholders to nominate a candidate for election to our Board for inclusion in our proxy materials in accordance with the "proxy access" provisions of our Bylaws, which are contained in Section 2.14. The "proxy access" provisions allow a stockholder, or a group of up to 20 stockholders (with funds having specified relationships constituting a single stockholder), who own (as defined in our Bylaws) three percent or more of our outstanding common stock continuously for at least three years, to nominate and include in the Company's proxy materials director candidates constituting up to two directors or 20% of the Board (rounded down to the nearest whole number), whichever is greater, provided that the stockholder(s) and the nominee(s) satisfy the requirements specified in our Bylaws (including similar information requirements to those set forth in Section 2.8 of our Bylaws).

Our Bylaws are available on our website at www.huntsman.com in the "Investor Relations" section. We will also furnish copies of our Bylaws free of charge to any person who requests them. Requests for copies should be directed to the Corporate Secretary, 10003 Woodloch Forest Drive, The Woodlands, Texas 77380 or to CorporateSecretary@huntsman.com. For additional information about stockholder nominations, including nominations for the 2018 annual meeting of stockholders, see "Stockholder Proposals and Director Nominations for the 2018 Annual Meeting."

Table of Contents

​ ​

From time to time, the Governance Committee may request additional information from the nominee or the stockholder. The Governance Committee uses the same process to screen all potential candidates, regardless of the source of the recommendation. The Governance Committee determines whether the candidate meets our minimum qualifications and specific qualities and skills for directors and whether requesting additional information or an interview is appropriate. Except as described under "Stockholder Proposals and Director Nominations for the 2018 Annual Meeting," the procedures set forth in Section 2.8 of our Bylaws and our "proxy access" provisions of our Bylaws are the exclusive means for a stockholder to make director nominations or submit other proposals before an annual or special meeting of the stockholders.

STOCKHOLDER COMMUNICATIONS POLICY

Stockholders and other interested parties may communicate directly and confidentially with the Board, the non-management directors, the independent directors or the Lead Independent Director by sending a letter addressed to the intended recipients, c/o Corporate Secretary, Huntsman Corporation, 10003 Woodloch Forest Drive, The Woodlands, Texas 77380 or by sending an e-mail specifying the intended recipients to CorporateSecretary@huntsman.com. The Corporate Secretary will review such communications and, if appropriate, forward them only to the intended recipients. Communications that do not relate to the responsibilities of the intended recipients as directors of Huntsman (such as communications that are commercial or frivolous in nature) will not be forwarded. In addition, communications that appear to be unduly hostile, intimidating, threatening, illegal or similarly inappropriate will not be forwarded. A copy of our Stockholder Communications Policy is available on our website at www.huntsman.com.

CORPORATE GOVERNANCE GUIDELINES

The Board has adopted Corporate Governance Guidelines, and the Governance Committee is responsible for implementing the guidelines and making recommendations to the Board concerning corporate governance matters. The guidelines are available on our website at www.huntsman.com. We will also furnish copies of the guidelines free of charge to any person who requests them. Requests for copies should be directed to the Corporate Secretary, 10003 Woodloch Forest Drive, The Woodlands, Texas 77380 or to CorporateSecretary@huntsman.com.

Among other matters, the guidelines provide for the following:

•

membership on the Board is made up of a majority of independent directors who, at a minimum, meet the criteria for independence required by the NYSE;

•

each regularly scheduled Board meeting includes an executive session of the non-management directors;

•

the independent directors will meet in executive session at least once annually;

•

the Board and its committees each conduct an annual self-evaluation;

•

non-management directors are not permitted to serve as a director for more than three other public companies;

•

our Chief Executive Officer is not permitted to serve as a director for more than two other public companies;

•

directors are expected to attend all meetings of the Board and of the committees of which they are members;

•

directors not also serving as executive officers are required to offer their resignation effective at the next annual meeting of stockholders upon reaching their 75th birthday (subject to certain exceptions);

•

directors are required to offer their resignation upon a change in their principal occupation;

•

directors should function consistent with the highest level of professional ethics and integrity; and

•

to effectively discharge their oversight duties, directors have full and free access to our officers and employees.

Despite Mr. Shoemaker already having reached his 75th birthday, the Board determined that due to his important continued contributions to the Board and the difficulty of finding a comparable replacement, Mr. Shoemaker should be nominated to serve for an additional one year term ending in 2018.

This Compensation Discussion and Analysis, or CD&A, provides information regarding how we paid our executives in 2016, including the following named executive officers, or "NEOs":

COMPENSATION SUMMARY

Performance Highlights in 2016

One of the primary objectives of our executive compensation program is to align our executive officers' pay with our financial performance and the performance of our common stock as measured by total stockholder return, or "TSR".

Historically, adjusted EBITDA was the primary financial metric used to measure our executive officers' performance under our annual cash performance award program. In response to feedback from the investment community, we publicly committed to generate free cash flow of $350 million in 2016. In connection with this commitment, we set a goal of improving working capital management by reducing days inventory outstanding, or "DIO." Accordingly, our 2016 annual cash performance award program included free cash flow and DIO targets, which together accounted for either 35% or 40% of the amount payable to each of our NEOs. Specific achievements in 2016 include the following:

How We Paid for Performance in 2016

Our executive compensation program is designed such that a significant portion of each officer's total target direct compensation is performance-based. On average, 72% of total target direct compensation of our NEOs was at risk, tied to annual performance measures and the performance of our common stock.

Mix of Total Target Direct Compensation in 2016⁽¹⁾

(1)

"Total target direct compensation" consists of (i) annual base salary, (ii) the target annual cash performance award opportunity for 2016, and (iii) the aggregate grant date fair value of long-term equity incentive awards granted in 2016. The amounts actually realized by our NEOs with respect to the annual cash performance awards and long-term equity incentive awards granted in 2016 depend, as applicable, on the level of attainment of the relevant performance goals and the value of our common stock when the awards vest or are exercised.

The greatest driver of the realizable value of compensation for our NEOs is the performance of our common stock price over time. The chart below provides comparisons of the target and realizable values of our CEO's compensation over the last three years as of the end of each year. In 2014 and 2015, when our stock price declined, the realizable value of compensation also declined. In 2016, when we experienced a 73.4% increase in TSR, the realizable value of compensation increased in a corresponding manner.

Realizable pay for each year is defined as the sum of: (1) salary, (2) annual cash performance award payout, and (3) the value of equity incentive awards granted in that year (i.e., performance share units at target, restricted stock units and the "in the money" value of stock options) calculated using our stock price as of the last trading day of each fiscal year.

Stockholder Outreach and Consideration of our 2016 Say-on-Pay Vote

We maintain regular contact with our external investors regarding our business strategy and our efforts to create long-term value for both our stockholders and debt holders. As discussed above, going into 2016, the investment community had expressed the desire to see free cash flow generation improve. In designing our 2016 cash performance award program, the Compensation Committee took this feedback into consideration in determining to base a portion of our executive officers' compensation under our annual cash performance award program on achievement of free cash flow and DIO performance goals..

At our 2016 annual meeting, 76% of total votes cast (excluding abstentions) voted in favor of our say-on-pay proposal. In designing the executive compensation program for 2017, the Compensation Committee considered the overall support that prior say-on-pay proposal received and decided not to make significant changes to our executive compensation program design. However, the Compensation Committee did make changes to our 2017 peer group or "Proxy Peers," as defined below in "—How We Determine Executive Compensation—Compensation Benchmarking." The Proxy Peers were modified to exclude some of the larger cap companies against whom we compete and were made partially in response to stockholder feedback and in connection with the transformation of our company as a result of the upcoming spin-off of our Pigments & Additives division.

Overall, we believe our compensation programs are effective in implementing our primary compensation objectives. In the past, based in part on stockholder feedback, the Compensation Committee has made changes to our compensation programs to further strengthen the alignment between our pay and performance. These changes have included the grant of performance share units to our NEOs targeting TSR relative to a group of peers, altering our Executive Chairman's equity-based grants to include performance share units and stock options, changes to the metric weightings of our Executive Chairman's annual cash performance award design and reducing his target and maximum achievable amounts.

OBJECTIVES OF HUNTSMAN'S EXECUTIVE COMPENSATION PROGRAM

The primary objective of our overall executive compensation program is stockholder value creation. In support of this objective, our executive compensation program is designed to: (i) align pay with performance; (ii) attract, motivate and retain executives critical to our long-term success by providing a competitive compensation structure; (iii) align our executives' interests with those of our stockholders; (iv) encourage long-term focus; and (v) discourage excessive risk-taking. The chart below indicates the key features of our executive compensation program and how they align with our objectives.

ELEMENTS OF HUNTSMAN'S EXECUTIVE COMPENSATION PROGRAM

Additional information about our executive compensation program is provided below, along with a discussion of how various compensation elements align with our compensation objectives.

TOTAL DIRECT COMPENSATION

We provide our executive officers with a mix of pay that reflects our belief that executive officers should have elements of their compensation tied to both short- and long-term performance. The Compensation Committee strives to align the relative proportion of each element of total direct compensation with the competitive market and our objectives, as well as to preserve the flexibility to respond to the continually changing global environment in which we operate. While the Compensation Committee reviews the competitiveness of each NEO's total direct compensation, it does not target specific percentiles among peer companies when setting compensation levels. Generally, as employees move to higher levels of responsibility with greater ability to influence our financial results, the percentage of performance-based pay will increase. Total direct compensation received by our NEOs comprises the following elements:

A detailed discussion of 2016 total target direct compensation awarded to our NEOs and graphical illustrations of the proportionate amount of performance-based compensation, is set forth below in "—2016 Executive Compensation Decisions."

OTHER ELEMENTS OF COMPENSATION

In addition to the elements of total target direct compensation described above, our executive compensation program includes other elements of compensation that are designed primarily to attract, motivate and retain executives critical to our long-term success and to provide a competitive compensation structure overall.

2016 EXECUTIVE COMPENSATION DECISIONS

TOTAL TARGET DIRECT COMPENSATION

The charts below illustrate the amount of 2016 total target direct compensation allocated to each component for the Executive Chairman, the CEO and the other NEOs. In light of their unique and indispensable roles, which are described below, we structure the compensation of our Executive Chairman and CEO to provide a total compensation package toward the higher end of the competitive range for executives holding comparable positions. We structure the compensation of our other executives to provide a total compensation package that is similar to the total compensation package provided to executives holding comparable positions or having similar qualifications at our Proxy Peers and other comparable companies (each as described below under "—How We Determine Executive Compensation").

The amounts actually realized by these executive officers with respect to the annual cash performance awards and long-term equity incentive awards granted in 2016 depend, as applicable, on the level of attainment of the relevant performance goals and the value of our common stock when the awards vest or are exercised.

This mix of pay elements represents our belief that the executive officers should have elements of their compensation tied to both short- and long-term objectives. The Compensation Committee's decisions regarding the mix of pay reflects our compensation philosophy, market reference data provided by Meridian and each officer's role in achieving our strategic objectives.

COMPENSATION FOR OUR EXECUTIVE CHAIRMAN AND OUR CEO

As CEO, Peter R. Huntsman leads our company, oversees the development and implementation of our strategy, directs our operations and business divisions, and is responsible for ensuring our company's long-term success. To align Peter R. Huntsman's compensation with his role, we provide a significant portion of his compensation in the form of equity-based incentives tied to the long-term performance of our common stock.

In his role as Executive Chairman, Jon M. Huntsman supports our CEO in the execution of his duties, especially the development of our vision and strategy. He also serves as an ambassador for our company, which includes promoting our brand, maintaining key relationships and exploring strategic opportunities, and mentoring senior executives and new Board members. Based on his role, his compensation was historically weighted more heavily towards cash awards to encourage specific actions in the applicable year.

In response to stockholder feedback, the Compensation Committee has made changes to the structure and value of Jon M. Huntsman's compensation. The mix of his equity-based grants was altered to include performance share units and stock options in addition to restricted stock, and the grant date fair value of his awards has been reduced by 16% from 2014 to 2017. Further, the portion of his annual cash performance awards tied to achievement of measurable financial goals was increased to 80% to align with the methodology used for our CEO, and the target value of his annual cash performance awards has been reduced by 51% from 2014 to 2017. In the aggregate, his target total compensation has decreased by 30% from 2014 to 2017.

​

2016 BASE SALARY CHANGES

The Compensation Committee determined that the base salary of Jon M. Huntsman and Peter R. Huntsman remained competitively positioned relative to market levels and, as a result, elected not to increase their salaries in 2016. Messrs. Esplin, Hankins and Stryker received modest increases to their base salary rates consistent with the salary adjustments provided to our employee population generally; however, Mr. Hankins' base salary remains higher than that of comparable positions within our peer group to reflect the added responsibilities of his role as CEO—Asia Pacific and his responsibility for both operational and financial performance of our Polyurethanes division.

2016 ANNUAL CASH PERFORMANCE AWARD

Our annual cash performance awards are designed to reward our executive officers for achievement of annual performance goals set by the Compensation Committee.

2016 Award Pool.    Each year, the Compensation Committee establishes an award pool program, which provides a mechanism to fund the annual cash performance awards based on achievement of a baseline performance hurdle established by the Compensation Committee. The award pool, together with the establishment of the baseline performance hurdle and a corresponding maximum award level, facilitates the Compensation Committee's intention that the annual cash performance awards qualify for tax deductibility under Section 162(m) of the Internal Revenue Code.

For those executives whose compensation was subject to the deductibility limits of Section 162(m), 2016 cash performance awards were contingent upon achievement of a baseline performance hurdle tied to corporate adjusted EBITDA that was established by the Compensation Committee. This baseline performance hurdle was achieved for 2016. Under the formula used to establish the award pool, the maximum amount that could be paid to officers participating in the award pool as a group was 2% of actual corporate adjusted EBITDA. In addition, individual award amounts were limited to an allocated portion of the award pool for each participating officer and the stockholder approved maximum of $15 million as provided in our Prior Stock Incentive Plan (the 2016 Stock Incentive Plan contains the same maximum limitation). These limits established the maximum annual dollar denominated cash performance awards that could be paid while the Compensation Committee retained discretion to pay lesser amounts based on the Compensation Committee's evaluation of the established performance measures, weightings and target and maximum award guidelines described below. Actual awards to officers covered by the award pool program were based on the Compensation Committee's assessment of our overall corporate performance, as well as the financial and strategic performance objectives discussed below, utilizing the negative discretion permitted by Section 162(m).

2016 Performance Measures and Goals.    In addition to the award pool described above, the Compensation Committee selects financial and strategic performance measures that must be achieved for payment of individual cash performance awards. The Compensation Committee selects performance measures that are important to our operations and contribute to the

​ ​

creation of stockholder value. The following table provides additional detail regarding the selected performance measures for the 2016 annual cash performance awards:

The Compensation Committee also established threshold, target and maximum performance goals for each of the financial performance measures relevant to our NEOs.

Targets are set at aggressive levels requiring significant effort to achieve. Achievement levels between threshold and target result in payouts from 0% to 100% of target awards. Achievement levels between target and maximum result in payouts from 100% to 200% of target awards. If we achieve corporate adjusted EBITDA of less than 85% of target, the payout for all other components may be capped at target. If corporate adjusted EBITDA is less than 75% of target, the threshold goal, then payment of any other component of the award would be at the discretion of our CEO and the Compensation Committee. The Compensation Committee believes that requiring a minimum adjusted EBITDA threshold be met to receive any payment with

respect to the annual cash performance awards both aligns executives' interests with those of stockholders and prevents excessive annual cash performance award payments in times when our financial performance fails to meet our expectations.

2016 Annual Cash Performance Award Design.    The Compensation Committee establishes target annual cash performance award guidelines for the NEOs set as a percentage of their base salaries (other than the Executive Chairman). The following table summarizes the target and maximum annual cash performance award guidelines, performance measures and corresponding weightings for each of our NEOs for 2016.

The target and maximum cash performance award guideline amounts for the NEOs were set to generally align with competitive levels relative to comparable executive positions at our Proxy Peers and other chemical and general industrial companies. The Compensation Committee assigns different performance measures and weightings for each NEO in order to align annual incentives with the performance measures most relevant to each officer's role and most within the particular officer's control. Potential payouts of individual annual cash performance awards depends upon both company performance and individual contributions to our success, with the target and maximum award amounts serving as guidelines for ultimate payouts.

2016 Financial Performance.    The 2016 targets were designed to require significant effort to achieve, yet to be realistic enough to incentivize our executive officers' performance. For 2016, actual performance and performance as a percentage of targets were as follows:

2016 EH&S Compliance Performance.    The EH&S compliance objectives were as follows:

For Messrs. Esplin and Stryker, these EH&S compliance objectives were achieved above target for process safety objectives and below target for the injury reduction objective. Mr. Hankins' performance was above target for both process safety and injury reduction objectives, in each case, for the Polyurethanes division.

Performance in Strategic and Operational Objectives.    

For 2016, the Compensation Committee set certain strategic and operational objectives for Jon M. Huntsman and Peter R. Huntsman. Their performance against these objectives was as follows:

​

​

2016 Annual Cash Performance Awards.    Based on the results discussed above, the Compensation Committee awarded the following annual cash performance awards:

LONG-TERM EQUITY COMPENSATION

For 2016, the Compensation Committee approved awards of stock options, time-based restricted stock and performance share units, which vest upon the achievement of relative TSR milestones. The Compensation Committee believes relative TSR is an appropriate long-term performance metric for the performance share unit awards because it promotes strong stockholder alignment and is a prevalent metric used by other companies.

The long-term equity incentive awards granted to each NEO in 2016 comprised a mix of stock options (30% value), restricted stock (40% value) and performance share units (30% value). The Compensation Committee targeted long-term equity compensation awards for the NEOs at levels intended to competitively position the total target direct compensation of the executive officers and to reflect the individual roles and contributions of our NEOs. The targeted award amounts were converted to a number of shares based on the grant date fair value of the respective award. The 2016 long-term equity incentive awards approved for the NEOs were as follows:

The restricted stock and stock option awards granted in 2016 are subject to a three-year ratable annual vesting schedule that requires service for a continuous three-year period to become fully vested.

The performance share unit awards granted in 2016 vest and lapse their associated restrictions on December 31, 2018, subject to the achievement of relative TSR performance metrics during the performance period from January 1, 2016 to December 31, 2018 and subject to continued service. If our absolute TSR is negative, the number of performance share units that will be vested at the end of the performance period is capped at the target number of performance share units. The performance share unit awards are settled in stock upon vesting, and any dividends paid with respect to the underlying shares are accumulated and paid when and to the extent the award vests and is earned, either in cash or additional shares at the Compensation Committee's election.

The company peer group used to determine relative TSR performance (the "2016 Performance Peers") represents industry-specific public companies against whom we compete for market share. Although there is some overlap between the two groups, the 2016 Performance Peers differ from our Proxy Peers, described below, because these are companies whose valuations are influenced by similar financial measures and we compete against these companies for market share and investor capital. As

​ 34  |  HUNTSMAN 2017 PROXY

​

Table of Contents

​ ​

described below, the Proxy Peers are companies against whom we compete in the global chemical industry for business opportunities and executive talent. The 2016 Performance Peers are as follows:

For each 2016 Performance Peer, TSR is measured using a 20 trading day stock price average at the beginning and end of the performance period to smooth out any volatility. Determination of payouts, if any, will be made based on the Company's TSR percentile performance relative to the 2016 Performance Peers at the end of the performance period. The maximum number of performance share units that may be earned under the program is 200% of the target number of shares granted if the Company's TSR performance ranks in the 90^th percentile of the 2016 Performance Peers. If the Company's TSR performance ranks below the 25^th percentile of the 2016 Performance Peers, there will be no payout. Median performance results in payout at target.

Additional details regarding these 2016 grants are provided under "Executive Compensation—Grants of Plan-Based Awards in 2016" below. None of the awards granted in 2016 provide for automatic accelerated vesting upon termination of employment or the occurrence of a change of control, except Jon M. Huntsman's 2016 award provides for accelerated vesting automatically upon a change of control. See "Executive Compensation—Potential Payments upon Termination or Change in Control" below for more information.

HOW WE DETERMINE EXECUTIVE COMPENSATION

Under the direction of the Compensation Committee and in coordination with our compensation consultant, Meridian, our CEO and our Senior Vice President, Global Human Resources coordinate the annual review of the executive compensation program. This review includes an evaluation of our performance, corporate goals and objectives relevant to compensation, and compensation payable under various circumstances, including upon retirement or a change of control. In making its decisions regarding each executive officer's compensation, the Compensation Committee considers the nature and scope of all elements of the executive's total compensation package, the executive's responsibilities and his or her effectiveness in supporting our key strategic, operational and financial goals. This review includes an evaluation of each executive officer's historical pay and career development, individual and corporate performance, competitive practices and trends and other compensation issues.

COMPENSATION BENCHMARKING

To assist in its determination of the 2016 target total direct compensation levels for our executive officers, the Compensation Committee considered information included in a compensation benchmarking review prepared by Meridian. The benchmarking review provided competitive market data for each element of compensation, as well as information regarding incentive plan designs and pay practices for executives in similar positions among a selected peer group of companies (the "Proxy Peers"). Information in the compensation benchmarking review served as a reference in the Compensation Committee's overall assessment of the competitiveness of our executive compensation program.

The Proxy Peers are representative of the companies against whom we compete in the global chemical industry for business opportunities and executive talent. Criteria used to select the Proxy Peer companies include financial measures (i.e., revenue, market capitalization, net income) and the industry segment in which we operate (i.e., organic chemical products and inorganic chemical products). For our compensation benchmarking review for 2016, our Proxy Peers comprised the following twelve companies:

The Compensation Committee reviews the composition of the Proxy Peers annually, resulting in some variation in the composition of the group from time to time. No changes to the Proxy Peer companies were made for purposes of 2016 compensation decisions. For 2017 compensation decisions, however, partially in response to stockholder feedback to exclude some of the larger cap companies against whom we compete and in connection with the transformation of our company as a result of the upcoming spin-off of our Pigments & Additives division. The Compensation Committee made more significant changes to our Proxy Peers. For 2017, the Compensation Committee removed Dow Chemical, EI du Pont de Nemours and Ecolab, and added Avery Dennison, Chemours, Olin, PolyOne, Sealed Air, Valspar and Westlake Chemical.

In addition to competitive market data for the Proxy Peers, and to assess benchmark data for positions in which pay information is not publicly disclosed, the Compensation Committee also considered competitive market data across a broader group of chemical and general industrial companies. These data points are provided by the Equilar Executive Compensation Survey and were included in the compensation benchmarking review. The Compensation Committee considers competitive ranges among our Proxy Peers and these broader industry groups, but does not use the benchmark data to target specific percentiles within these groups.

The Compensation Committee believes the combination of these perspectives and points of reference offers an appropriate basis for assessing the competitiveness of the compensation for our NEOs.

INDEPENDENCE OF COMPENSATION ADVISERS

Since 2011, the Compensation Committee has retained Meridian as its compensation consultant. Meridian is an independent compensation consulting firm and does not provide any services to us outside of matters pertaining to executive officer and director compensation. Meridian reports directly to the Compensation Committee, which is solely responsible for determining the scope of services performed by Meridian and the directions given to Meridian regarding the performance of such services. Meridian attends Compensation Committee meetings as requested by the Compensation Committee.

The Compensation Committee determined that the services provided by Meridian to the Compensation Committee during 2016 did not give rise to any conflicts of interest. The Compensation Committee made this determination by assessing the independence of Meridian under the six independence factors adopted by the SEC and incorporated into the NYSE Corporate Governance Listing Standards. Further, in making this assessment, the Compensation Committee considered Meridian's written correspondence to the Compensation Committee that affirmed the independence of Meridian and the partners, consultants and employees who provide services to the Compensation Committee on executive and director compensation matters.

The Compensation Committee has on occasion sought the advice of Vinson & Elkins LLP, a law firm that represents and receives fees from our company with respect to legal services provided in other areas. Based on a letter from Vinson & Elkins assessing their independence under the six independence factors adopted by the SEC and incorporated into the NYSE Corporate Governance Listing Standards, the Compensation Committee determined that the services provided by Vinson & Elkins to the Compensation Committee during 2016 also did not give rise to any conflicts of interest.

COMPENSATION POLICIES AND PRACTICES

STOCK OWNERSHIP GUIDELINES

The Board has adopted Director and Executive Stock Ownership Guidelines (the "Guidelines") to more closely align our directors' and executives' interests with our stockholders' interests and to encourage directors and executives to make decisions that will be in our long-term best interests—through all industry cycles and market conditions. The Guidelines require directors and executive officers to achieve and maintain ownership of our stock equal to six times base salary for the CEO, three times base salary for all other executive officers and three times the annual cash retainer for directors. The stock ownership requirement is based on the participant's base salary or annual retainer (as applicable) and the closing stock price on July 15 of each calendar year.

During any year in which a participant's ownership target is not met, he or she is required to retain at least 50% of net shares delivered through the Huntsman's stock incentive plans ("net shares" means the shares remaining after deducting shares for the payment of taxes and, in the case of stock options, after deducting shares for payment of the exercise price of stock options). Shares acquired by a participant prior to becoming subject to the Guidelines are not subject to the retention restriction. There are exceptions to the retention requirement for estate planning, gifts to charity, education and a participant's primary residence. In addition, hardship exemptions may be made in rare instances. A copy of the Guidelines is available on our website at www.huntsman.com.

As of March 10, 2017, all of our directors exceeded the ownership levels specified in the Guidelines. The following table provides the minimum stock ownership level for each NEO and the percentage of the ownership guideline achieved by the officer as of March 10, 2017:

CLAWBACK POLICY

In September 2014, the Compensation Committee adopted an Executive Compensation Clawback Policy for executive officers. Under this policy, the Company may recover performance-based compensation that was based on achievement of quantitative performance targets if an executive officer engaged in fraud or intentional illegal conduct resulting in a financial restatement. The Company may also recover any awards made to an executive during the prior three years should the executive engage in activity that results in a financial restatement.

PROHIBITED TRANSACTIONS

Our Insider Trading Policy includes trading restrictions, which prohibit employees, directors and related persons from engaging in short-term, hedging or speculative transactions in our securities. Such persons may not execute transactions in short sales, options, such as puts and calls, or any other derivative securities or margin accounts. In addition, while we do not prohibit pledging shares, persons subject to the policy are required to exercise caution when holding securities in a margin account where such securities could be pledged as collateral.

COMPENSATION POLICIES AND PRACTICES AS THEY RELATE TO RISK MANAGEMENT

The Compensation Committee believes that our compensation programs are appropriately designed to provide a level of incentives that does not encourage our executive officers and employees to take unnecessary risks in managing their respective business divisions or functions and in carrying out their employment responsibilities. As discussed above, a substantial portion of our executive officers' compensation is performance-based, consistent with our approach to executive compensation. Our annual cash performance award program is designed to reward annual financial and/or strategic performance in areas considered critical to our short and long-term success and features a cap on the maximum amount that can be earned in any

​ ​

single year. In addition, we measure performance in many areas other than company profit, such as environmental, health and safety goals, cost-saving initiatives and corporate compliance, to determine an executive's annual cash performance award. We believe this discourages risk-taking for short-term profits at the detriment of the long-term health of our company. Likewise, our long-term equity incentive awards are directly aligned with long-term stockholder interests through their link to our stock price, TSR and multi-year ratable vesting schedules. Our executive stock ownership guidelines further provide a long-term focus by requiring our executives to personally hold significant levels of our stock. In addition, we implemented a clawback policy to discourage risk-taking that focuses excessively on short-term financial performance. The Compensation Committee believes that the various elements of our executive compensation program sufficiently incentivize our executives to act based on the sustained long-term growth and performance of our company.

ACCOUNTING AND TAX TREATMENT OF THE ELEMENTS OF COMPENSATION

We account for stock-based awards, including stock options, restricted stock and performance share unit awards, in accordance with FASB ASC Topic 718 (formerly Statement of Financial Accounting Standards No. 123R).

The financial reporting and income tax consequences to us of individual compensation elements are important considerations for the Compensation Committee when it is analyzing the overall level of compensation and the mix of compensation among individual elements. Overall, the Compensation Committee seeks to balance its objective of ensuring an effective compensation package for the NEOs with the desire to maximize the immediate deductibility of compensation—while ensuring an appropriate and transparent impact on reported earnings and other closely followed financial measures.

In making its compensation decisions, the Compensation Committee has considered the implications of Section 162(m) of the Internal Revenue Code. Section 162(m) of the Internal Revenue Code disallows a tax deduction by us for individual executive compensation exceeding $1 million in any taxable year for our CEO and the other three most highly compensated senior executive officers (other than our CEO and Chief Financial Officer), unless the compensation is "performance-based" under a plan that is approved by our stockholders and that meets certain other technical requirements. As a result, the Compensation Committee intends to design a substantial portion of the total compensation package for each NEO to qualify for the "performance-based" compensation exemption from the deductibility limit. However, the Compensation Committee does have the discretion to design and use compensation elements that may not be deductible under Section 162(m) when necessary for competitive reasons, to attract or retain a key executive, to enable us to retain flexibility in maximizing our pay for performance philosophy or where achieving maximum tax deductibility would not be in our best interest.

COMPENSATION COMMITTEE REPORT

The Compensation Committee has reviewed and discussed Huntsman Corporation's Compensation Discussion and Analysis for the fiscal year ended December 31, 2016 as set forth above with Huntsman management. Based on this review and discussion, the Compensation Committee recommended to the Board of Directors that the Compensation Discussion and Analysis be included in this Proxy Statement.

NARRATIVE DISCLOSURE TO SUMMARY COMPENSATION TABLE AND GRANTS OF PLAN-BASED AWARDS TABLE

Information regarding the elements of our executive compensation program for 2016 is provided above under "Compensation Discussion and Analysis." The following is a discussion of material factors necessary to obtain an understanding of information disclosed under "—2016 Summary Compensation Table" and "Grants of Plan-Based Awards in 2016" that is not otherwise discussed in the Compensation Discussion and Analysis.

Aircraft Use Policy.    We have an Aircraft Use Policy to carefully manage use of our aviation assets in a manner that best meets the goals of improving senior management's effectiveness and availability. Under this policy, certain of our executive officers may have personal use of company aircraft to the extent that such executive officer reimburses our company for the costs associated with their respective personal use of company aircraft. To mitigate security concerns and to maximize time available to spend on company business, the Compensation Committee permits our Executive Chairman and CEO to have personal use of company aircraft without cost subject to availability and to the Compensation Committee's authority to limit any such personal use. For 2016, personal use for our Executive Chairman was limited to 150 flight hours while personal use by our CEO was unlimited. We do not make gross-up payments for out-of-pocket tax obligations resulting from any personal use of our company aircraft.

Air Travel Allowance.    Pursuant to our Business Expense and Travel Policy, we offer all employees the opportunity to receive an air travel allowance to encourage cost savings to us. When an employee is authorized to fly business class but chooses to fly coach class, we pay the employee an amount equal to half the difference between the lowest cost business class ticket and the fare paid up to a maximum of $2,000.

Company Car.    We provide executive officers with leased vehicles for business use, which executives may also use for personal transportation. Executive officers are responsible for the taxes on imputed income associated with the personal use of these vehicles.

Foreign Assignment.    In accordance with our practice with respect to employees on assignment in a foreign country, Mr. Hankins entered into a letter agreement on November 1, 2000 with our subsidiary Huntsman Polyurethanes Americas detailing the terms of his secondment from Huntsman Polyurethanes (UK) Ltd. The primary purpose of this letter agreement is to provide Mr. Hankins with details regarding repatriation to his home country following the completion of his foreign assignment. This letter agreement also defines the initial elements of Mr. Hankins' compensation package, including base salary and an annual cash performance award, and provides for customary expatriation arrangements, including an international location allowance expressed as a percentage of annual salary.

Family Travel.    Travel costs for family members of employees or consultants are reimbursable by the Company under limited circumstances. Employees and consultants are generally responsible for any taxable income associated with this reimbursement.

PENSION BENEFITS IN 2016

The table below sets forth information on the pension benefits for the NEOs under our pension plans, each of which is more fully described in the narrative following the table. The amounts reported in the table below equal the present value of the accumulated benefit at December 31, 2016 for the NEO under each plan based upon the assumptions described below.

In the U.S., we sponsor the Huntsman Defined Benefit Pension Plan (the "Huntsman Pension Plan"), a tax-qualified defined benefit pension plan. Effective July 1, 2004, the formula used to calculate future benefits under the Huntsman Pension Plan was changed to a cash balance formula. The benefits accrued under the plan as of June 30, 2004 were used to calculate opening cash balance accounts. Of our NEOs, Messrs. Jon M. Huntsman, Peter R. Huntsman, Esplin and Stryker were participants in the Huntsman Pension Plan in 2016. The Huntsman Pension Plan was closed to new participants effective July 1, 2014.

The Huntsman Supplemental Executive Retirement Plan (the "Supplemental Executive Retirement Plan") is a non-qualified supplemental pension plan that provides benefits for designated executive officers based on certain compensation amounts not included in the calculation of benefits payable under the Huntsman Pension Plan. Of our NEOs, Messrs. Jon M. Huntsman, Peter R. Huntsman, Esplin and Stryker were participants in the Supplemental Executive Retirement Plan in 2016. The compensation taken into account for these NEOs under the Supplemental Executive Retirement Plan includes amounts in excess of the qualified plan limitations. The Supplemental Executive Retirement Plan benefit is calculated as the difference between (1) the benefit determined using the Huntsman Pension Plan formula with unlimited base salary plus annual cash performance awards, and (2) the benefit determined using base salary plus annual cash performance awards as limited by federal regulations.

Both plans express benefits as a hypothetical cash balance account established in each participant's name, and a participant's account receives two forms of credits: "pay credits" and "interest credits." Pay credits equal a percentage of a participant's compensation and are credited to a participant's account on an annual basis. "Compensation" for this purpose includes both salary and annual cash performance awards. "Compensation" under the Huntsman Pension Plan is subject to the compensation limit applicable to tax-qualified plans of $265,000 for 2016. The benefit that would be available under the Huntsman Pension Plan, but for this limitation, is provided under the Supplemental Executive Retirement Plan. The applicable pay credit percentage for our NEOs ranges between 8% and 12% depending on the participant's combined age and years of service as of the start of each plan year. The 2016 pay credits for the Huntsman Pension Plan are $31,800 for Jon M. Huntsman, $31,800 for Peter R.

​ ​

Huntsman, $27,825 for Mr. Esplin and $21,200 for Mr. Stryker. The 2016 pay credits for the Supplemental Executive Retirement Plan are $290,568, $327,720, $88,137, and $52,040 for Messrs. Jon M. Huntsman, Peter R. Huntsman, Esplin, and Stryker, respectively.

"Interest credits" for a plan year are based on the 30 year U.S. Treasury yield for November of the prior year. The minimum annual interest credit rate is 5.0%. The 2016 interest credits for the Huntsman Pension Plan are $9,416, $105,344, $80,646, and $10,994 for Messrs. Jon M. Huntsman, Peter R. Huntsman, Esplin, and Stryker. The 2016 interest credits for the Supplemental Executive Retirement Plan are $221,447, $437,023, $23,903, and $38,197 for Messrs. Jon M. Huntsman, Peter R. Huntsman, Esplin, and Stryker, respectively.

Pursuant to the terms of the Huntsman Pension Plan, at termination of employment for any reason after having completed at least three years of service, a participant will receive the amount then credited to the participant's cash balance account in an actuarially equivalent joint and survivor annuity (if married) or single life annuity (if not married). Participants may also choose from other optional forms of benefit, including a lump-sum payment in the amount of the cash balance account. For participants in the prior Supplemental Executive Retirement Plan (including NEOs Peter R. Huntsman and Mr. Esplin), the Huntsman Pension Plan also includes a minimum benefit that guarantees that a participant's benefit will not be less than the benefit accrued under the prior formula at transition (July 1, 2004) plus the benefit attributable to pay credits, with interest credits, beginning July 1, 2004. Under the prior plan provisions, the monthly basic benefit equaled one-twelfth of 1.4% of average earnings multiplied by pension service prior to January 1, 2000, plus 1.5% of average earnings multiplied by pension service after January 1, 2000, less 50% of the Social Security benefit prorated by pension service, payable as a life annuity to the participant. The prior Supplemental Executive Retirement Plan mirrored the benefit from the Huntsman Pension Plan. For participants taking an annuity, early retirement reductions apply if retirement occurs before normal retirement age (defined as age 65 with 5 years of service) and on or after the earlier of (i) both attaining age 50 and age plus vesting service equal to 80 or more, or (ii) age 55 with 10 years of vesting service. The effect of these reductions is to reduce the annuity amount paid by 5% per year for each year beginning at age 59 until age 50 where the amount paid would be 50%. As of December 31, 2016, Peter R. Huntsman is our only NEO eligible for early retirement.

Vested benefits under the Supplemental Executive Retirement Plan are paid 30 days following a participant's separation from service, unless the participant is a "specified employee" for purposes of Section 409A of the Internal Revenue Code ("Section 409A"), in which case payment will be delayed for six months. Vested benefits are paid in a single cash lump sum unless the participant elects: (1) a life annuity, (2) a life annuity with payments guaranteed for 120 months, or (3) a joint and survivor annuity providing survivor benefits equal to 50% or 100% (as elected by the participant) of the annuity payable to the participant. Benefits are unvested until the earlier to occur of: (1) completion of ten years of service, (2) termination on account of death or "Disability" or on or after attainment of "Normal Retirement Age," or (3) termination without "Reasonable Cause." Each NEO is fully vested in his benefit under the Supplemental Executive Retirement Plan. Jon M. Huntsman is currently receiving distributions from his Huntsman Pension Plan and Supplemental Executive Retirement Plan accounts in connection with his prior retirement from Huntsman in 2001.

"Disability" under the Huntsman Pension Plan provides that, for a disabled participant, service and benefit accruals continue for 24 months. After 24 months, disabled participants are deemed to be terminated participants. Disability is defined as total and permanent disability, as determined by the administrator of our long-term disability plan.

"Normal Retirement Age" is retirement eligibility upon age 65 with 5 years of service under the Huntsman Pension Plan and Supplemental Executive Retirement Plan.

"Reasonable Cause" means: (1) the grossly negligent, fraudulent, dishonest or willful violation of any law or the material violation of any of our significant policies that materially and adversely affects us, or (2) the failure of the participant to substantially perform his duties.

We also sponsor retirement benefit plans in connection with our operations in the U.K. Of our NEOs, Mr. Hankins participates in the Huntsman Pension Scheme for U.K. associates in the Polyurethanes division. The Huntsman Pension Scheme (U.K.) in which Mr. Hankins participates provides a benefit of 2/3rd of final pensionable compensation times actual years of service through February 29, 2012, divided by total possible service to retirement. Final pensionable compensation is notional base salary received during the 12 months prior to retirement. Normal retirement age for the Huntsman Pension Scheme (U.K.) is age 62 and participants retiring as early as age 50 may receive a reduced pension amount between 37% at age 50 and 66.7% at age 61. These benefits also include U.K. social security benefits. As of December 31, 2016, Mr. Hankins had approximately 32.6 years of credited service in the U.K., and is fully vested in these benefits. The Huntsman Pension Scheme (U.K.) was frozen to new participants as of February 29, 2012 and, after that date, benefits for current participants under the plan will only increase based on changes in salary.

NONQUALIFIED DEFERRED COMPENSATION IN 2016

We provide executive officers based in the United States the opportunity to participate in two defined contribution savings plans: (1) the 401(k) Plan; and (2) the Supplemental Savings Plan. Jon M. Huntsman does not participate in the 401(k) Plan or the Supplemental Savings Plan. The 401(k) Plan is a tax-qualified broad-based employee savings plan; employee contributions up to 25% of base salary and annual cash performance awards are permitted up to dollar limits established annually by the Internal Revenue Service ("IRS"). The Supplemental Savings Plan is a nonqualified salary deferral plan and allows designated executive officers to defer up to 75% of eligible salary and up to 75% of annual cash performance awards. The Supplemental Savings Plan also provides benefits for participants in the form of company matching contributions based on certain compensation amounts not included in the calculation of benefits payable under the 401(k) Plan because of limits under federal law on compensation ($265,000 in 2016). As required by Section 409A, deferrals must be elected in the calendar year preceding the year in which the compensation deferred is earned. Peter R. Huntsman did not defer any earnings into the Supplemental Savings Plan in 2016.

Executive officers were previously offered the opportunity to participate in the SEMPP, a non-qualified plan that provided benefits not allowed under the MPP due to IRS compensation and allocation limits. The MPP was a tax-qualified broad-based employee savings plan that was merged into our 401(k) Plan on October 15, 2014. Contributions under the SEMPP and the MPP ceased September 1, 2014; however, our NEOs still maintain a balance in the SEMPP, which is reflected in the table below.

The table below provides information on the nonqualified deferred compensation of the NEOs in 2016 under the Supplemental Savings Plan and the SEMPP. The NEOs cannot withdraw any amounts from their nonqualified deferred compensation balances for a period of six months following the date of their termination of employment or retirement. No withdrawals or distributions were made in 2016

The Supplemental Savings Plan provides for payment of benefits to a participant upon the earlier to occur of a "Change of Control" or a termination of the participant's service. Benefits paid upon a "Change of Control" are always paid in a single lump-sum payment. Benefits payable upon a separation from service can be made (at the election of the participant) in either a single lump-sum payment or in substantially equal installments over a period selected by the participant that does not exceed 10 years. In addition, the participant may request distribution of all or a portion of the amounts credited to his account upon an

​ ​

"Unforeseeable Emergency." Payments upon separation from service will be delayed six months in accordance with Section 409A in the event a participant is a "specified employee" for purposes of Section 409A. The Supplemental Savings Plan was amended on September 1, 2014 to increase the eligible match to 4% of pay. Additionally, for individuals who had been participants in the MPP or SEMPP plans, we provide a 6% non-discretionary contribution to the Supplemental Savings Plan. This non-discretionary contribution was implemented to offset the effect of discontinuation of all contributions to the MPP and SEMPP plans effective August 31, 2014. Jon M. Huntsman and Mr. Stryker were not eligible to participate in the MPP or SEMPP; therefore, they were not eligible to receive non-discretionary contributions into the Supplemental Savings Plan.

The Supplemental Savings Plan defines a "Change of Control" as the occurrence of either of the following events:

•

Any person becomes the owner of 35% or more of our outstanding voting stock (other than certain persons affiliated with us).

•

The replacement of a majority of the Board over a two-year period except in cases where (1) such replacement is not approved by a vote of at least a majority of the incumbent Board or (2) the election or nomination of such replacement Board members is by certain of our affiliates.

In addition, any "Change of Control" must also constitute a change in control for purposes of Section 409A.

A participant will be deemed to have incurred an "Unforeseeable Emergency" if he suffers a severe financial hardship resulting from (1) an illness or accident with respect to him, his spouse or a dependent, (2) the loss of property due to casualty or (3) other similar extraordinary and unforeseeable circumstances arising as a result of events beyond the participant's control determined by us to constitute an unforeseeable emergency for purposes of Section 409A.

The SEMPP was a nonqualified plan for senior executives that provided for benefits not allowed under the MPP due to IRS compensation and allocation limits. Employees are vested in this account upon meeting 10 years of service, upon attaining normal retirement age, death or disability, or upon termination of employment without reasonable cause. Effective September 1, 2014, we no longer make contributions to the SEMPP.

The plan provides for the payment of vested benefits upon a participant's separation from service except to the extent the participant is a "specified employee" for purposes of Section 409A in which case benefits will be delayed six months. A participant's benefits vest on the earlier to occur of (1) completion of ten years of service, (2) termination on account of death, "Disability," or on or after attainment of "Normal Retirement Age," or (3) termination without "Reasonable Cause." "Disability," "Normal Retirement Age," and "Reasonable Cause" have the same meanings as set forth above in our description of the Supplemental Executive Retirement Plan under "—Pension Benefits in 2016," except that a "Disability" must also constitute a disability for purposes of Section 409A. Other than Jon M. Huntsman and Mr. Stryker, who are not eligible to participate, each NEO is currently vested in his SEMPP benefit. Benefits are payable in one of the following forms elected by a participant:

•

A single lump-sum payment;

•

A single life annuity;

•

A joint and survivor annuity; or

•

Installments over a period selected by the participant not in excess of 10 years.

Participants are entitled to elect the investment of their accounts under both the Supplemental Savings Plan and the SEMPP. Although no assets may actually be invested, a participant's benefit value is based on the gains or losses of the investments they choose. No above market or preferential earnings are provided under our nonqualified defined contribution plans because the investment choices available under the plans are identical to the investment choices available in the 401(k) Plan. Consequently none of the earnings reported in the "Nonqualified Deferred Compensation in 2016" table above are included in the Summary Compensation Table for 2016. Participants may change their investment options at any time by contacting the plan record keeper.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE OF CONTROL

Our NEOs may receive compensation in connection with an involuntary termination of employment or a change of control pursuant to the terms of the following arrangements:

•

the Executive Severance Plan (in the case of the NEOs other than Jon M. Huntsman and Peter R. Huntsman);

•

the Severance Agreements with Jon M. Huntsman and Peter R. Huntsman;

•

the 2016 Huntsman Stock Incentive Plan and the Prior Stock Incentive Plan; and

•

other existing plans and arrangements in which our NEOs participate.

Executive Severance Plan.    Through our Executive Severance Plan, we provide our executive officers, including our NEOs, two times base salary as severance in order to attract and retain the executive talent necessary for our business. The level of severance is evaluated each year. Pursuant to our Executive Severance Plan, each participant is entitled to receive a single cash lump sum severance payment in the event of a termination without Reasonable Cause or upon a termination by the executive for Good Reason.

"Reasonable Cause" means: (1) the grossly negligent, fraudulent, dishonest or willful violation of any law or the material violation of any of our significant policies that materially and adversely affects us, or (2) the failure of the participant to substantially perform his duties.

"Good Reason" means a voluntary termination of employment by the participant as a result of (1) a materially detrimental reduction or change to the job responsibilities or in the current base compensation of the Participant, or (2) within a period of 12 months following a Change of Control, changing the participant's principal place of work by more than 50 miles, in each case, which is not remedied by the Company within 30 days after receipt of notice.

A "Change of Control" is defined pursuant to the 2016 Huntsman Stock Incentive Plan and means the occurrence of any of the following:

•

An acquisition by any person of 20% or more of the combined voting power of our outstanding voting securities.

•

The consummation of a reorganization, merger, consolidation or other transaction in which our stockholders do not own, immediately thereafter, more than 20% or more of the combined voting power of the resulting entity in substantially the same proportion as their stock ownership prior to the transaction.

•

The sale or disposition of all or substantially all of our assets.

•

A majority change in the incumbent directors of the Board.

•

An approval by the Board or our stockholders of a complete or substantially complete liquidation or dissolution.

The Executive Severance Plan also provides the continuation of medical benefits for U.S. participants for up to two years following termination (which will be in the form of a lump sum cash payment equal to the COBRA premium at the time of departure multiplied by the severance period multiplied by 150%), and outplacement services for a period of one year.

A participant is not entitled to benefits under the Executive Severance Plan if the participant is reemployed with an employer in our controlled group, if the participant refuses to sign a waiver and release of claims in our favor if requested, or if the participant is entitled to severance benefits under a separate agreement or plan maintained by us.

As a citizen of the U.K., Mr. Hankins is an entitled participant in the business severance plan. At the time of a termination, payout potential from both the Executive Severance Plan and the U.K. business plan would be considered, then the plan generating the more generous payout would be used. Mr. Hankins is entitled to 12 months' notice and 116.67% of his annual base pay upon termination as is the case with all U.K. associates in our Polyurethanes division. Accordingly, his potential severance payment is 26 times base monthly salary upon termination. The Executive Severance Plan provides greater severance amounts than the U.K. business severance plan for Mr. Hankins in the event of a termination without "Reasonable Cause" or upon a termination by the executive for "Good Reason."

​ ​

Severance Agreements with Jon M. Huntsman and Peter R. Huntsman.    Effective January 1, 2013, we entered into Severance Agreements with Jon M. Huntsman and Peter R. Huntsman. The Severance Agreements have a five year term and are designed to provide enhanced severance benefits in the event of a change of control. During the term of the agreements, Jon M. Huntsman and Peter R. Huntsman are not eligible to participate in the Executive Severance Plan.

Pursuant to the agreements, if Jon M. Huntsman or Peter R. Huntsman is terminated (i) by us other than for Reasonable Cause or (ii) by the executive for Good Reason, the executive will be entitled to the same payments and benefits specified in the Executive Severance Plan.

For Jon M. Huntsman, upon the occurrence of a change of control, all unvested equity awards under the 2016 Huntsman Stock Incentive Plan and the Prior Stock Incentive Plan will become immediately vested, regardless of whether a termination has occurred. In addition, if his employment is terminated by us without Reasonable Cause or by him for Good Reason, in either case, within three years following a change of control, we will pay Jon M. Huntsman a lump sum cash amount equal to (1) three times his then current annual base salary, (2) three times the largest annual bonus paid to him during any of the three previous calendar years, (3) the largest annual bonus amount paid to him during any of the previous three calendar years, reduced by an amount equal to the pro rata portion of such bonus attributable to the number of days in the calendar year of his termination that elapse following his termination date, and (4) an amount equal to $42,890, representing the loss of certain health and welfare benefits provided to him in connection with his employment.

In the case of Peter R. Huntsman, in the event his employment is terminated by us other than for Reasonable Cause or by him for Good Reason, in either case, within two years following a change of control, we will pay him a lump sum cash amount equal to 2.9 times his then current annual base salary.

Payment of any amounts described above is contingent upon each executive executing (and not revoking) a release of claims in favor of the Company. The Severance Agreements do not contain tax gross-up provisions; however, the agreements do include a "best of net" provision, which provides that, if any payments or benefits to which the executive is entitled in connection with his termination are likely subject to the tax imposed by Section 4999 of the Internal Revenue Code, the payment will (1) be reduced such that Section 4999 does not apply or (2) paid in full, whichever produces the better net after tax position to the executive.

The Severance Agreements utilize the same definition of Reasonable Cause as set forth above with respect to our Executive Severance Plan. A termination for Good Reason pursuant to the Severance Agreements means voluntary termination of employment as a result of (1) the significant detrimental reduction or change to the executive's job responsibilities or in his current base compensation, or (2) a change in the executive's principal place of work by more than fifty miles from his principal place of work, which is not remedied by the Company within 30 days after receipt of notice.

For purposes of the Severance Agreements, a "change of control" means (1) an acquisition of beneficial ownership by an individual, entity, or group of 20% or more of our then outstanding shares of common stock or of our outstanding voting securities (subject to certain exceptions), (2) a majority change in the incumbent directors of the Board, (3) the consummation of a reorganization, merger or consolidation or sale or other disposition of all or substantially all of our assets (subject to certain limitations), or (4) a complete liquidation or dissolution of the Company.

Stock Incentive Plan Awards.    Long-term equity incentive awards granted under the Huntsman's stock incentive plans provide for accelerated vesting upon a Change of Control or certain other events, including certain terminations of employment or service, at the discretion of our Compensation Committee. Any such provision made by the Compensation Committee could benefit all participants in the Huntsman's stock incentive plans, including the NEOs. If there is a Change of Control, the Compensation Committee may, in its discretion, provide for:

•

assumption by the successor company of an award, or the substitution thereof for similar options, rights or awards covering the stock of the successor company;

•

acceleration of the vesting of all or any portion of an award;

•

changing the period of time during which vested awards may be exercised (for example, but not by way of limitation, by requiring that unexercised, vested awards terminate upon consummation of the change of control);

•

payment of substantially equivalent value in exchange for the cancellation of an award; and/or

•

issuance of substitute awards of substantially equivalent value.

Other arrangements.    As more fully described under "—Pension Benefits in 2016" above, our executives are entitled to payments pursuant to the terms and conditions of the Huntsman Pension Plan or local variants and the Supplemental Executive Retirement Plan. In addition, pursuant to our Supplemental Savings Plan, upon a change of control (as defined in the Supplemental Savings Plan), participants, including the NEOs, may elect to receive the present value of the benefits payable to them under this plan. Amounts payable under the Supplemental Savings Plan and SEMPP are described under "—Nonqualified Deferred Compensation in 2016" above.

As described under "—Pension Benefits in 2016" above, pursuant to the Huntsman Pension Scheme (U.K.), Mr. Hankins is entitled to receive annual benefits of up to ²/3 of pensionable compensation, which are reduced if his actual years of service are less than the total possible years of service to retirement. Upon a qualifying disability, Mr. Hankins' benefits would be 75% of pensionable compensation until age 65. Mr. Hankins is entitled to a minimum death benefit equal to 66.6% of the accrued benefit and a lump sum equal to eight times pensionable compensation.

Quantification of Potential Payments and Benefits.    The table below reflects the compensation that may be payable to or on behalf of each NEO upon an involuntary termination or a change of control. The amounts shown assume that such termination or change of control was effective as of December 31, 2016. All equity acceleration values have been calculated using the closing price of our stock on December 30, 2016 (the last trading day of fiscal 2016) of $19.08. The actual amounts we will be required to disburse can only be determined at the time of the applicable circumstance.

AUDIT COMMITTEE PRE-APPROVAL POLICIES AND PROCEDURES

The Audit Committee has, by resolution, adopted policies and procedures regarding pre-approval of the performance by Deloitte & Touche LLP and affiliates of certain audit and non-audit services. Deloitte & Touche LLP and affiliates may not perform any service enumerated in Section 201(a) of the Sarbanes-Oxley Act of 2002, except as may otherwise be provided by law or regulation. Deloitte & Touche LLP and affiliates may not perform any service unless the approval of the Audit Committee is obtained prior to the performance of the services, except as may otherwise be provided by law or regulation. The Audit Committee has pre-approved the performance by Deloitte & Touche LLP and affiliates of certain audit and accounting services, certain tax services, and, provided that fees do not exceed $250,000 per individual project, certain other tax services and audit-related services. The Audit Committee has delegated to the committee chair the power to pre-approve services beyond those previously described, provided that no services may be approved that are prohibited pursuant to Section 201(a) of the Sarbanes Oxley Act of 2002 or that appear reasonably likely to compromise the independence of Deloitte & Touche LLP. Any pre-approval granted by the chair is reviewed by the Audit Committee at its next regularly scheduled meeting. In addition, the Audit Committee receives a report annually detailing the prior year's expenditures, consistent with the SEC's accountant fee disclosure requirements.

The Audit Committee has approved all audit and permissible non-audit services prior to such services being provided by Deloitte & Touche LLP and affiliates in accordance with these procedures.

AUDIT COMMITTEE REPORT

The Audit Committee (the "Committee") of the Board of Directors (the "Board") of Huntsman Corporation ("Huntsman") assists the Board in fulfilling its oversight responsibilities with respect to the external financial reporting process and the adequacy of Huntsman's internal controls over financial reporting and related disclosure controls and procedures, areas for which management has primary responsibility. Specific responsibilities of the Committee are set forth in the Audit Committee Charter, a copy of which can be found on Huntsman's website at www.huntsman.com. At its May 2017 meeting, the Board determined that all current Committee members, Messrs. Burns, Shoemaker, Sir Robert and Dr. Beckerle, meet the independence, experience and other qualification requirements of Rule 10A-3 of the Securities Exchange Act of 1934 and the New York Stock Exchange.

The independent registered public accounting firm is responsible for expressing an opinion on the conformity of Huntsman's audited financial statements with accounting principles generally accepted in the United States and for issuing its report on Huntsman's internal control over financial reporting. All audit and non-audit services provided to Huntsman by the independent registered public accounting firm are pre-approved by the Committee or by the Chair of the Committee pursuant to delegated authority, and the Committee considers the compatibility of such non-audit services with the independent registered public accounting firm's independence.

The Committee evaluates the performance of the independent registered public accounting firm each year and determines whether to re-engage the current firm or consider other audit firms. In doing so, the Committee considers the quality of the services provided by the independent registered public accounting firm, along with their capabilities, technical expertise, and knowledge of Huntsman's operations and industry. Based on these evaluations, the Committee decided to engage Deloitte & Touche LLP as Huntsman's independent registered public accounting firm for the year ending December 31, 2017. Although the Committee has the sole authority to appoint the independent registered public accounting firm, the Committee has continued its long-standing practice of recommending that the Board ask stockholders to ratify the appointment of the registered public accounting firm at Huntsman's annual meeting of stockholders.

The Committee has reviewed and discussed Huntsman's audited financial statements for the year ended December 31, 2017 with Huntsman's management. The Committee has discussed with Deloitte & Touche LLP the matters required to be discussed by Auditing Standard No. 61. The Committee has received the written disclosures and the letter from Deloitte & Touche LLP required by applicable requirements of the Public Company Accounting Oversight Board regarding Deloitte & Touche LLP's communications with the Committee concerning independence, and has discussed with Deloitte & Touche LLP its independence.

Based on the review and discussions referred to in the preceding paragraph, the Committee recommended to the Board that Huntsman's audited financial statements for the year ended December 31, 2017 be included in Huntsman's Annual Report on Form 10-K for the year ended December 31, 2017. This report was submitted by the current members of the Committee,

PROPOSAL 1—ELECTION OF DIRECTORS

The size of the Board is currently set at eight, all of whom are elected to serve until the 2017 annual meeting. The Governance Committee has recommended, and the Board has unanimously nominated, Messrs. Jon M. Huntsman, Peter R. Huntsman, Nolan D. Archibald, M. Anthony Burns, Wayne A. Reaud, Alvin V. Shoemaker, Dr. Mary C. Beckerle and Sir Robert J. Margetts for election. Each elected director will serve until our 2018 annual meeting, until a successor is elected and qualified, or until his or her earlier death, resignation or retirement. We did not pay any third-party fees to assist in the process of identifying or evaluating candidates nor did we receive any stockholder nominations for director.

The nominees receiving a majority of the votes cast at the Annual Meeting for the election of directors will be elected as directors. You may not cumulate your votes in the election of directors. Votes that are withheld from a director's election will be counted toward a quorum, but will not affect the outcome of the vote on the election of a director. If you are a street name stockholder and you do not provide your brokerage firm with voting instructions, your brokerage firm may not cast votes with respect to the shares that you beneficially own. These broker non-votes will have no effect on the election of the director nominees.

Unless otherwise indicated on the proxy, the persons named as proxies in the enclosed proxy will vote FOR each of the director nominees listed below. Although we have no reason to believe that any of the nominees will be unable to serve if elected, should any of the nominees become unable to serve prior to the Annual Meeting, the proxies will be voted for the election of such other persons as may be nominated by the Board.

It is our policy for directors to attend our annual meetings to provide an opportunity for stockholders to communicate directly with directors about issues affecting our company.

THE BOARD RECOMMENDS A VOTE "FOR" THE ELECTION OF EACH DIRECTOR NOMINEE.

PROPOSAL 2—NON-BINDING ADVISORY VOTE TO APPROVE THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS

Pursuant to Section 14A of the Securities Exchange Act of 1934, we are submitting a proposal to our stockholders for a non-binding advisory vote to approve the compensation of our NEOs as disclosed in this Proxy Statement in accordance with the compensation disclosure rules of the SEC. This say-on-pay proposal gives our stockholders the opportunity to express their views on the compensation of our NEOs. Currently, our stockholders are given the opportunity to cast an advisory vote on this topic annually, with the next opportunity occurring in connection with our 2018 annual meeting.

The guiding principles of our compensation policies and decisions include aligning each executive's compensation with our company's business strategy and the interests of our stockholders and providing incentives needed to attract, motivate and retain key executives who are important to our long-term success. Our overriding executive compensation philosophy is clear and consistent—we pay for performance. Consistent with this philosophy, a significant portion of the total compensation for each of our executives is directly related to our earnings and to other performance factors that measure our progress against the goals of our strategic and operating plans and the long-term performance of our common stock.

When casting your vote, we urge you to read the Compensation Discussion and Analysis section of this Proxy Statement, which discusses how our compensation design and practices reflect our compensation philosophy. The Compensation Committee and the Board believe that our compensation practices effectively implement our guiding principles. This is evidenced by our company's strong financial performance in 2016, as discussed in the Compensation Discussion and Analysis section.

The say-on-pay vote is not intended to address any specific item of compensation, but rather the overall compensation of our NEOs and the principles, policies and practices described in this Proxy Statement. Accordingly, the following resolution is submitted for stockholder vote at the Annual Meeting:

"RESOLVED, that the stockholders of Huntsman Corporation approve, on a non-binding advisory basis, the compensation of its named executive officers as disclosed in the proxy statement for the 2017 Annual Meeting pursuant to the compensation disclosure rules of the SEC, including the Compensation Discussion and Analysis, the Summary Compensation Table and other related tables and disclosures."

Approval of this proposal requires approval by holders of a majority of the shares represented in person or by proxy and entitled to vote at the Annual Meeting. Abstentions will be treated as votes against this proposal. If you are a street name stockholder and you do not provide your brokerage firm with voting instructions, your brokerage firm may not cast votes with respect to the shares that you beneficially own. These broker non-votes will have no effect on the vote.

While this vote is required by law, the result will not be binding on our company, the Board or the Compensation Committee, will not overrule any decisions made by the Board or the Compensation Committee, and will not require the Board or the Compensation Committee to take any specific action. Nevertheless, the Board and the Compensation Committee value the opinions of our stockholders and will carefully consider the outcome of the vote when making future compensation decisions for our NEOs. In particular, to the extent there is any significant vote against our NEOs' compensation as disclosed in this proxy statement, we will consider our stockholders' concerns, and the Compensation Committee will evaluate whether any actions are necessary to address those concerns.

THE BOARD RECOMMENDS A VOTE "FOR" THE ADVISORY VOTE
TO APPROVE NAMED EXECUTIVE OFFICER COMPENSATION.

PROPOSAL 3—NON-BINDING ADVISORY VOTE TO APPROVE THE PREFERRED FREQUENCY OF VOTES ON THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS

As described in Proposal 2 above, in accordance with Exchange Act Section 14A, our stockholders are being provided the opportunity to cast an advisory vote on our executive compensation program. The advisory vote on executive compensation described in Proposal 2 above is referred to as a "say-on-pay" vote. As required by Exchange Act Section 14A, this Proposal 3 affords stockholders the opportunity to cast an advisory vote on how often we should include a say-on-pay vote in our proxy materials for future annual stockholder meetings (or a special stockholder meeting for which our company must include executive compensation information in the proxy statement for that meeting). Under this Proposal 3, stockholders may vote on a non-binding basis to have the say-on-pay vote every year, every two years, or every three years. In addition, stockholders may abstain from voting on this Proposal 3. Exchange Act Section 14A requires the company to hold an advisory vote on the frequency of the say-on-pay vote at least once every six years.

We believe that say-on-pay votes should be conducted every year so that stockholders can provide us with direct and timely input on our executive compensation program. While our executive compensation programs are designed to promote a long-term connection between pay and performance, the Board recognizes that executive compensation disclosures are made annually and holding an annual advisory vote on executive compensation provides us with more direct and immediate feedback on our compensation disclosures. However, stockholders should note that because the advisory vote on executive compensation occurs well after the beginning of the compensation year, and because the different elements of our executive compensation programs are designed to operate in an integrated manner and to complement one another, in many cases it may not be feasible or feasible to change our executive compensation programs in consideration of any one year's advisory vote on executive compensation before the following year's annual meeting of stockholders.

The proxy card provides stockholders with the opportunity to choose among four options (1 year, 2 years, 3 years, or abstain) and, therefore, stockholders will not be voting to approve or disapprove the recommendation of the Board. Approval of this proposal requires approval by holders of a majority of the shares represented in person or by proxy and entitled to vote at the Annual Meeting. Because this proposal has three possible substantive responses (1 year, 2 years or 3 years), if none of the frequency alternatives receives the vote of the holders of a majority of the shares present, then we will consider stockholders to have approved the frequency selected by holders of a plurality of the shares present. Abstentions will be treated as votes against this proposal. If you are a street name stockholder and you do not provide your brokerage firm with voting instructions, your brokerage firm may not cast votes with respect to the shares that you beneficially own. These broker non-votes will have no effect on the vote.

Please note that this vote is advisory and not binding on our company or the Board in any way. The Board and the Compensation Committee will take into account the outcome of the vote, however, when considering the frequency of future advisory votes on executive compensation. The Board may decide now or in the future that it is in the best interests of our stockholders and our company to hold an advisory vote on executive compensation on a different frequency than the frequency receiving the most votes cast by our stockholders.

THE BOARD RECOMMENDS A VOTE "FOR" THE OPTION OF "1 YEAR"
AS THE PREFERRED FREQUENCY FOR ADVISORY VOTES ON EXECUTIVE COMPENSATION

PROPOSAL 4—RATIFICATION OF THE APPOINTMENT OF OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee has appointed Deloitte & Touche LLP to serve as our independent registered public accounting firm and to audit our consolidated financial statements for the fiscal year ending December 31, 2017. Deloitte & Touche LLP has served as our auditor since 1984. The Audit Committee has been advised by Deloitte & Touche LLP that neither the firm, nor any member of the firm, has any financial interest, direct or indirect, in any capacity in us or our subsidiaries. As a matter of good corporate governance, the Audit Committee has determined to submit its selection of Deloitte & Touche LLP to stockholders for ratification.

The proposal to ratify the appointment of Deloitte & Touche LLP as our independent registered public accounting firm will require approval by holders of a majority of the shares represented in person or by proxy and entitled to vote at the Annual Meeting. Abstentions will be treated as votes against this proposal. If you hold your shares in street name and do not provide timely voting instructions, your broker may exercise discretionary authority, thereby avoiding a broker non-vote.

If the selection of the independent registered public accounting firm is not ratified, the Audit Committee will reconsider its selection. Even if the selection is ratified, the Audit Committee in its discretion may direct the appointment of a different independent registered public accounting firm at any time if the Audit Committee believes that such a change would be in the best interest of our company and our stockholders.

One or more representatives of Deloitte & Touche LLP are expected to attend the Annual Meeting and will be available to respond to appropriate questions and, if they desire, will have an opportunity to make a statement.

THE BOARD RECOMMENDS A VOTE "FOR" THE RATIFICATION OF THE APPOINTMENT OF
DELOITTE & TOUCHE LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR 2017

STOCKHOLDER PROPOSALS AND DIRECTOR NOMINATIONS FOR THE 2018 ANNUAL MEETING

STOCKHOLDER PROPOSALS TO BE INCLUDED IN NEXT YEAR'S PROXY STATEMENT

Pursuant to the various rules promulgated by the SEC, stockholders interested in submitting a proposal for inclusion in our proxy materials and for presentation at the 2018 annual meeting may do so by following the procedures set forth in Rule 14a-8 under the Securities Exchange Act of 1934. In general, to be eligible for inclusion in our proxy materials, stockholder proposals must be received by our Corporate Secretary at our principal executive offices, located at 10003 Woodloch Forest Drive, The Woodlands, Texas 77380, no later than November 25, 2017.

Director Nominations and Stockholder Proposals for Presentation at the 2018 Annual Meeting

In addition to stockholder proposals submitted pursuant to the requirements of Rule 14a-8 as specified above, and as more specifically provided for in Section 2.8 of our Bylaws or the "proxy access" provisions of our Bylaws, for a nomination of persons for election to the Board or a proposal of business to be properly brought before the 2018 annual meeting, it must be either specified in the notice of the meeting given by our Corporate Secretary or otherwise brought before the meeting by or at the direction of the Board or by a stockholder entitled to vote and who complies with the applicable notice procedures set forth in our Bylaws. A stockholder making a nomination for election to the Board or a proposal of business for the 2018 annual meeting must deliver proper notice to our Corporate Secretary (c/o Corporate Secretary, Huntsman Corporation, 10003 Woodloch Forest Drive, The Woodlands, Texas 77380 or to CorporateSecretary@huntsman.com) not earlier than the close of business on the 120th calendar day prior to the first anniversary of the date of the 2017 Annual Meeting nor later than the close of business on the 90th calendar day prior to the first anniversary of the 2017 Annual Meeting. In other words, for a stockholder nomination for election to the Board (either pursuant to Section 2.8 of our Bylaws or the "proxy access" provisions of our Bylaws) or a proposal of business to be considered at the 2018 annual meeting, it should be properly submitted to our Corporate Secretary no earlier than Thursday, January 5, 2018 and no later than Saturday, February 4, 2018. If the date of our 2018 annual meeting changes by more than 30 calendar days before May 5, 2018 or more than 70 calendar days after May 5, 2018, then stockholder nominations and proposals must be received not earlier than the close of business on the 120th calendar day prior to the date of the 2018 annual meeting and not later than the close of business on the later of the 90th calendar day prior to the date of the 2018 annual meeting or the 10th calendar day following the calendar day on which public announcement of the date of 2018 annual meeting is first made by us.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table presents information regarding beneficial ownership of our common stock as of March 10, 2017 by:

•

each person who we know owns beneficially more than 5% of our common stock;

•

each of our directors and nominees;

•

each of our NEOs; and

•

all of our executive officers and directors as a group.

Under the regulations of the SEC, shares are generally deemed to be "beneficially owned" by a person if the person directly or indirectly has or shares voting power or investment power (including the power to dispose) over the shares, whether or not the person has any pecuniary interest in the shares, or if the person has the right to acquire voting power or investment power of the shares within 60 days, including through the exercise of any option, warrant or right. In accordance with the regulations of the SEC, in computing the number of shares of common stock beneficially owned by a person and the percentage ownership of such person, we deemed to be outstanding all shares of common stock subject to options or other rights held by the person that are currently exercisable or exercisable within 60 days of March 10, 2017. We did not deem such shares outstanding, however, for the purpose of computing the percentage ownership of any other person.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Securities Exchange Act of 1934 requires our directors and executive officers, among others, to file with the SEC and the NYSE an initial report of ownership of our common stock on Form 3 and reports of changes in ownership on Form 4 or Form 5. Persons subject to Section 16 are required by SEC regulations to furnish us with copies of all Section 16 forms that they file related to Huntsman stock transactions. Under SEC rules, certain forms of indirect ownership and ownership of our common stock by certain family members are covered by these reporting requirements. As a matter of practice, our administrative staff assists our directors and executive officers in preparing initial ownership reports and reporting ownership changes and typically files these reports on their behalf.

Based solely on a review of the reports furnished to us or written representations from reporting persons that all reportable transactions were reported, we believe that during 2016 all of our executive officers, directors and greater than 10% holders filed the reports required to be filed under Section 16(a) on a timely basis under Section 16(a).

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

POLICIES AND PROCEDURES

Effective February 1, 2007, the Board adopted a Related Party Transactions Policy, which includes the procedures for review, approval and monitoring of transactions involving our company and "related persons" (directors, executive officers, stockholders owning five percent or greater of our common stock, or their respective immediate family members). The policy covers any transaction involving amounts exceeding $120,000 in which a related person has a direct or indirect material interest.

The Compensation Committee reviews and approves all compensation paid to family members of directors and executive officers. All other related person transactions must be approved by the Audit Committee, which will approve the transaction only if it determines that the transaction is in, or is not inconsistent with, our interests. In evaluating the transaction, the Audit Committee will consider all relevant factors, including as applicable (1) the benefit to us in entering into the transaction; (2) the alternatives to entering into a related person transaction; and (3) whether the transaction is on terms comparable to those available to third parties.

​ ​

If a director is involved in the transaction, he or she will be recused from all discussions and decisions about the transaction. The transaction must be approved in advance of its consummation. The Audit Committee will periodically monitor the transaction to ensure that there are no changed circumstances that would render it advisable, or not inconsistent with such circumstances, to amend or terminate the transaction and will review the transaction annually to determine whether it continues to be in our interests.

The Compensation Committee approved the 2016 compensation decisions described below. The Audit Committee approved all other transactions described below, which were entered into after February 1, 2007 in accordance with the Related Party Transactions Policy, and continues to monitor arrangements described below consistent with the Related Party Transactions Policy.

TRANSACTIONS

Aircraft Sublease.    Our subsidiary Airstar Corporation ("Airstar") subleases a Gulfstream IV-SP Aircraft (the "Aircraft") from Jstar Corporation ("Jstar"), a corporation wholly owned by Jon M. Huntsman pursuant to a lease arrangement that expires in 2021. Under this arrangement, Airstar makes monthly sublease payments to Jstar of $122,996 and an aggregate of $6.95 million is payable through the end of the lease term. These monthly sublease payments are equal to the financing costs paid by Jstar to a leasing company and the arrangement does not result in a financial benefit to Jstar.

Office Building Lease.    We occupy and use a portion of an office building owned by the Huntsman Foundation, a private charitable foundation established by Jon M. and Karen H. Huntsman to further the charitable interests of the Huntsman family, pursuant to a lease. With the scheduled transition of employees to The Woodlands, Texas, the original lease was reduced by 50% effective February 2, 2016. During 2016, we made payments of $912,716 to the Huntsman Foundation under the lease, which includes a contractual 2% increase from 2015. The lease expires on December 31, 2018, subject to a five-year extension at our option.

Consulting Agreement.    Effective August 31, 2015, we entered into a Consulting Agreement with Jon M. Huntsman, Jr., one of our former directors and the former governor of Utah and U.S. Ambassador to Singapore and China. Pursuant to the Consulting Agreement, Jon M. Huntsman, Jr. agreed to: provide strategic advice to senior management and the board of the Company on political, economic and business matters; support development and continued maintenance of the Company's high value customers and significant business relationships across all regions; support development and continued maintenance of governmental and business relationships in developing economic regions, particularly in connection with markets and opportunities in India, China and Southeast Asia; participate in negotiations and discussions with business executives and leaders, government officials and/or dignitaries; and participate in such other meetings or discussions as may be requested by senior management of the Company upon reasonable notice. In exchange for these services, we agreed to pay Jon M. Huntsman, Jr. $50,000 per month through the term of the Consulting Agreement and up to $200,000 in additional compensation based on achievement of designated results as determined by the Board. The Consulting Agreement was renewed for one year effective August 31, 2016, subject to our right to extend the agreement for additional one year terms. Jon M. Huntsman, Jr. is the son of our Executive Chairman, Jon M. Huntsman and the brother of our Chief Executive Officer, Peter R. Huntsman.

Reimbursed employee.    Eight individuals who work for entities owned or controlled by Jon M. Huntsman are on our company's payroll, for which we are fully reimbursed and paid an administrative fee. One of these employees was paid compensation in excess of $120,000 in 2016 ($127,400).

Other Transactions with the Huntsman Family.    The following table shows compensation paid to members of the Huntsman family (other than NEOs and directors as disclosed herein) for services as officers or employees in fiscal 2016 that involve amounts exceeding $120,000. All amounts paid for 2016 were approved by the Compensation Committee, which reviews and approves all annual and other compensation arrangements and components for corporate and executive officers and their family members who are employees.
