This proxy statement (“Proxy Statement”) is furnished in connection with the solicitation by management of Mercer International Inc. of proxies for use at the annual meeting of our shareholders (“Shareholders”) to be held in Oceanview Suite 7, R-Restaurant Level, Pan Pacific Hotel, 999 Canada Place, Vancouver, British Columbia, Canada at 10:00 a.m. (Vancouver time) on June 1, 2018 (the “Meeting”), or any adjournment, postponement or rescheduling thereof.

References to “we”, “our”, “us”, the “Company” or “Mercer” in this Proxy Statement mean Mercer International Inc. and its subsidiaries unless the context clearly suggests otherwise. References to “fiscal year” means an annual period ended December 31. Information herein for 2017 generally refers to our 2017 fiscal year.

If a proxy (a “Proxy”) is properly executed and received by us prior to the Meeting or any adjournment, postponement or rescheduling thereof, our shares of common stock, par value $1.00 per share (the “Shares”) represented by such Proxy will be voted in the manner directed. In the absence of voting instructions, the Shares will be voted for the proposals set out in the accompanying Notice of Annual Meeting of Shareholders. Please see the Proxy for voting instructions.

A Proxy may be revoked at any time prior to its use by filing a written notice of revocation of proxy or a later dated Proxy with the Company’s registrar and transfer agent at Proxy Services, c/o Computershare, Inc., P.O. Box 505008, Louisville, KY 40233. A Proxy may also be revoked by submitting another Proxy with a later date over the Internet, by telephone, to our registrar and transfer agent or by voting in person at the Meeting. Attending the Meeting will not, in and of itself, constitute revocation of a Proxy.

The holders of one-third of the outstanding Shares entitled to vote at the Meeting, present in person or represented by Proxy, constitutes a quorum for the Meeting. Shares represented by proxies that reflect abstentions or broker non-votes (i.e., Shares held by a broker/dealer or other nominee that are not voted

because the broker/dealer or other nominee does not have the authority to vote on a particular matter) will be counted as Shares that are present and entitled to vote for the purposes of determining the presence of a quorum for the Meeting.

In accordance with rules of the Securities and Exchange Commission (the “SEC”), we are furnishing our proxy materials related to the Meeting primarily via the Internet, instead of mailing printed copies of those materials to each Shareholder. Beginning on or around April 20, 2018, we will mail a Notice of Internet Availability to our Shareholders (other than those who had previously requested electronic or paper delivery) containing instructions on how to access our proxy materials, including this Proxy Statement and our annual report for 2017 (the “2017 Annual Report”), which includes our annual report on Form 10-K for the fiscal year ended December 31, 2017 (the “Form 10-K” or “2017 Form 10-K”). The Notice of Internet Availability also instructs you on how to vote over the Internet. This process is designed to expedite Shareholders’ receipt of proxy materials, lower the cost of the Meeting and help conserve natural resources. However, if you would prefer to receive printed proxy materials, please follow the instructions included in the Notice of Internet Availability. If you have previously elected to receive our proxy materials electronically, you will continue to receive these materials via e-mail unless you elect otherwise. This Proxy Statement, accompanying Proxy and the 2017 Annual Report will be available on or around April 20, 2018 on our corporate website and at www.proxyvote.com and www.investorvote.com for Shareholders.

Proxies may also be solicited by mail, telephone, facsimile or personal contact by our directors, officers or regular employees without additional compensation. All proxy-soliciting expenses in connection with the solicitation of votes for the Meeting will be borne by the Company.

Our Board has set the close of business on March 23, 2018 as the record date (the “Record Date”) for the determination of Shareholders entitled to notice of and to vote at the Meeting or any adjournment, postponement or rescheduling thereof.

Voting by Mail. Complete, date, sign and mail the Proxy in the enclosed postage pre-paid envelope (if you received a paper copy of the proxy materials by mail). If you mark your voting instructions on the Proxy, your Shares will be voted as you instruct. Please see the Proxy for voting instructions.

Voting in Person. If you are a registered Shareholder and attend the Meeting, you may vote in person as instructed at the Meeting. However, if you hold your Shares in street name and you wish to attend and vote your Shares at the Meeting, you will first need to obtain a legal

proxy from your broker, bank or other intermediary that is the holder of record of your Shares and bring it with you to the Meeting. Otherwise, you will not be permitted to vote in person at the Meeting.

Voting by Telephone. Call 1-800-652-VOTE (8683) from any touch-tone telephone and follow the instructions. You should have your Proxy in hand when you call.

If you own your Shares through a brokerage account or in other nominee form, you should follow the instructions you receive from the record holder to see which voting methods are available.

Your Proxy will not be revoked if you attend the Meeting but do not vote.

If you own your Shares through a broker or other nominee and wish to change your vote, you must send those instructions to your broker or nominee.

Votes are counted as present at the Meeting if a Shareholder either:

Abstentions and broker non-votes (i.e., Shares held by a broker/dealer or other nominee that are not voted because the broker/dealer or other nominee does not have the authority to vote on a particular matter) will be counted for the purposes of determining the presence of a quorum.

If you sign and return your Proxy without voting instructions, your Shares will be voted in accordance with the Board’s recommendations for the proposals described in this Proxy Statement.

In accordance with our articles of incorporation and bylaws, each as may be amended from time to time, our Board is authorized to fix the number of the Company’s directors at not less than three (3) and not more than thirteen (13) and has fixed the number of directors at nine (9). There is currently a full complement of nine (9) members of the Board. Directors are elected at each annual meeting of Shareholders to hold office until the next annual meeting. The persons identified below are nominated to be elected at the Meeting for the ensuing year. Other than Alan Wallace and Linda J. Welty, all of the nominees are currently directors of the Company previously elected by Shareholders. Despite the expiration of a director’s term, the director shall continue to serve until the director’s successor is elected and qualified or until there is a decrease in the number of directors. If for any unforeseen reason any of the nominees for director declines or is unable to serve, Proxies will be voted for the election of such other person or persons as shall be designated by the directors. Our Board has no reason to believe that any of the nominees will be unable or will decline to serve, if elected. Proxies received which do not specify a choice for the election of the nominees will be voted “FOR” each of the nominees. Proxies cannot be voted for more than nine (9) persons since that is the total number of nominees.

Set forth below is certain information furnished to us by the director nominees. There are no family relationships among any of our current directors, nominees or executive officers. None of the corporations or other organizations referenced in the biographical information below is a parent, subsidiary or other affiliate of the Company.

We believe that our directors should satisfy a number of qualifications, including demonstrated integrity, a record of personal accomplishments, a commitment to participation in board activities and other traits discussed below in “Our Director Nominations Process”. We also endeavor to have a Board representing a range of skills and depth of experience in areas that are relevant to and contribute to the Board’s oversight of our operations. The Board believes its current size is appropriate for the size and scope of our business.

We believe that the following nominees represent a desirable mix of backgrounds, skills and experiences. Additionally, we believe that the specific leadership skills and other experiences of the nominees described below, particularly in the areas of forest products, senior executive leadership, financial accounting/reporting, public company board experience, investment management, capital markets and finance, provide us with the perspectives and judgment necessary to guide our strategies and monitor their execution.

Following the biographical information for each director nominee, we describe the key experience, qualifications and skills our director nominees bring to the Board that, for reasons discussed below, are important in our business. The Board considered these experiences, qualifications and skills and the directors’ other qualifications in determining to recommend that the directors be nominated for election:

In order to provide Shareholders with a meaningful role in the outcome of director elections, our Board has adopted a provision on voting for directors in uncontested elections as part of our Governance Guidelines. In general, this provision provides that any nominee in an uncontested election who receives more votes “Withheld” for his or her election than votes “For” his or her election must promptly tender an offer of resignation following certification of the Shareholder vote to our Governance and Nominating Committee which will, without the participation of any director so tendering his or her resignation, consider the resignation and recommend to the Board whether to accept the resignation offer. The Board, without the participation of any director so tendering his or her resignation, will act on the Governance and Nominating Committee’s recommendation within 90 days following certification of the Shareholder vote. Any such tendered resignation will be evaluated in light of the best overall interests of the Company and its Shareholders. Our Board’s decision will be disclosed in a Form 8-K furnished by the Company to the SEC within four business days of the decision. If our Board decides to turn down the tendered

resignation, or to pursue any additional action (as described above or otherwise), then the Form 8-K will disclose the Board’s reasons for doing so. If each member of the Governance and Nominating Committee receives a Majority Withheld Vote at the same election, then the independent directors who did not receive a Majority Withheld Vote will act as a committee to consider the resignation offers and recommend to the Board whether to accept them.

Any director who offers to resign pursuant to this provision will not participate in any actions by either the Governance and Nominating Committee or the Board with respect to accepting or turning down his or her own resignation offer.

The complete terms of this provision are included in our Governance Guidelines which can be found at the “Investors - Governance” link on our website at www.mercerint.com.

The election of directors at the Meeting is an uncontested election.

Board Tenure and Refreshment

Maintaining an appropriate balance of tenure among directors is part of the Board’s consideration. Longer serving directors bring valuable experience and knowledge with respect to our business, industry and strategic and operational challenges.

Newer directors bring, along with their own personal experiences, fresh perspective and ideas.

We believe that directors should not be subject to term or age limits. While term and age limits could facilitate fresh ideas and viewpoints being consistently brought to the Board, we believe they are counter-balanced by the disadvantage of causing the loss of directors who over a period of time have

developed insight into our strategies, operations and risks and continue to provide valuable contributions to Board deliberations. We believe that our decision not to establish term or age limits is consistent with the prevailing practice among companies in the S&P 500. We recognize that certain governance stakeholders have suggested that longer-serving directors may have decreased independence and objectivity; however, we believe that arbitrarily removing knowledgeable directors and the oversight consistency they bring – particularly during periods of management change – weighs against strict restrictions on director tenure. Ultimately, it is our Board’s responsibility to establish board refreshment policies, using its discretion in the best interests of the Company and our Shareholders.

Our Board has adopted Governance Guidelines, which include written charters for each Board committee, our Code of Business Conduct and Ethics and a Securities Law Compliance Policy, all of which are intended to provide a set of guidelines to assist the Board in ensuring that we adhere to proper standards of good governance. Our Board has also adopted a Hedging Transactions Policy, a Whistleblower Policy and an Anti-Corruption Policy.

Such guidelines, codes and policies, which are reviewed regularly and revised as necessary or appropriate in response to changing regulatory requirements and evolving best practices, are available on our website at www.mercerint.com under “Investors - Governance”.

Our Governance Guidelines:

Our Code of Business Conduct and Ethics, which applies to our directors and all of our executive officers, is designed to deter wrongdoing and promote:

Our Securities Law Compliance Policy applies to the handling of our material non-public information or other companies with whom we deal and the buying and selling of our stock and other securities and those of other companies.

Our Hedging Transactions Policy, which applies to our directors and all of our executive officers, is designed to prohibit such individuals from hedging their Mercer stock, including trading in options, puts, calls or other derivative instruments relating to our securities.

Our Whistleblower Policy provides a set of procedures for our employees to report, on a confidential basis, their concerns or complaints about questionable accounting or auditing matters or violations of legal or regulatory requirements and for the Audit Committee to receive and respond to such concerns and complaints.

Our Anti-Corruption Policy is designed to expand upon the provisions of our Code of Business Conduct and Ethics relating to international operations and ensure compliance by us and our directors, officers, employees and agents with the United States Foreign Corrupt Practices Act of 1977 (FCPA) and other applicable anti-corruption laws.

Board Meetings and Attendance

In 2017:

Mr. Lauritzen and Ms. Orr have each decided not to stand for re-election at the Meeting. Our Board has determined to propose Alan Wallace and Linda Welty as director nominees to fill such vacancies. In addition, our Board has determined to appoint Keith Purchase to serve as Lead Director for a three-year term effective June 1, 2018 and as the Chair of our Governance and Nominating Committee.

The NASDAQ listing standards require that a majority of the members of a listed company’s board of directors be independent. Based upon the

NASDAQ rules, our Board has determined that the following seven director nominees are independent and represent 78% of our director nominees:

Our Board is responsible for overseeing the exercise of corporate power and seeing that our business and affairs are managed to meet our own stated goals and objectives and that the long-term interests of our Shareholders are served.

The Governance and Nominating Committee, which is made up entirely of independent directors, is

responsible for the continuing review of the governance structure of the Board, and for recommending to the Board governance structures and practices best suited for our particular situation. This committee determines what leadership structure it deems appropriate, based on factors such as experience of the applicable individuals and the current business environment.

Our Board believes that it should maintain flexibility to select our Chairman and its board leadership structure from time to time and our policies do not preclude our CEO from also serving as Chairman of the Board. Our Executive Chairman, Mr. Lee, was formerly our CEO until 2015 when he became Executive Chairman. Our Board believes Mr. Lee serving as Executive Chairman allows the Board to benefit from Mr. Lee’s in-depth knowledge of our business and industry as well as leadership in formulating and implementing strategic initiatives.

In considering its leadership structure, the Board has taken a number of factors into account. In particular,

the Governance and Nominating Committee has sought to ensure that independent backgrounds and opinions dominate both the Board and the Board’s committees. Consequently, the Board, which consists of seven independent directors out of nine, who are highly qualified and experienced, exercises a strong, independent oversight function. This oversight function is enhanced by the fact that all of the Chairs of our Board committees are independent directors, and the Audit Committee, Compensation and Human Resources Committee and Governance and Nominating Committee are composed entirely of independent directors.

Our Board leadership structure and practices, including the appointment of a Lead Director for a three-year term and meetings in executive sessions, support the independence of our non-employee directors. Meetings are also held formally and

informally from time to time with our Executive Chairman and Chief Executive Officer for discussion of relevant subjects.

Executive Sessions

Our Board believes it is important to have executive sessions without the Chief Executive Officer, Executive Chairman and other members of management, which are scheduled during every meeting of the Board. Our independent directors have robust and candid discussions at these executive sessions, during which they evaluate the performance of the Chief Executive Officer, Executive Chairman and other senior officers, our governance practices, the reports of our independent registered public accountants, the meetings themselves and any other relevant matter.

During 2017, Mr. Lauritzen was Lead Director and chaired all 7 executive sessions of our independent directors. In 2017, our independent directors determined to have two executive sessions at each meeting of the Board, both before and after such meetings.

Committees of the Board

Our Board currently has four standing committees: the Audit Committee, the Compensation and Human Resources Committee, the Governance and Nominating Committee and the Environmental, Health and Safety Committee. Our committee meetings are generally open to all directors, who often voluntarily attend all committee meetings.

The Board oversees the proper safeguarding of the assets of the Company, the maintenance of appropriate financial and other internal controls and our compliance with applicable laws and regulations and proper governance. Inherent in these responsibilities is the Board’s understanding and oversight of the various risks facing us. The Board

does not view risk in isolation. Risks are considered in virtually every business decision and as part of our business strategy. The Board recognizes that it is neither possible nor prudent to eliminate all risk. Indeed, purposeful and appropriate risk-taking is essential for us to be competitive on a global basis and to achieve our long-term strategic objectives.

Effective risk oversight is an important priority of the Board. The Board has implemented a risk governance framework designed to:

While the Board oversees risk management, our management is charged with managing risk. We have robust internal processes and an effective internal control environment which facilitate the identification and management of risks and regular communication with the Board. These include an enterprise risk management program under the leadership of the Chief Financial Officer, regular internal management disclosure committee meetings, Codes of Business Conduct and other policies, strong internal controls and a comprehensive external audit process. The Board and the Audit Committee monitor and oversee the evaluation of the effectiveness of the internal controls and the risk management program. Management communicates routinely with the Board, Board committees and individual directors on the significant risks identified and how they are being managed. Directors are free to, and indeed often do, communicate directly with senior management.

The Board implements its risk oversight function both as a whole and through delegation to Board committees, which meet regularly and report back to the full Board. Board committees assist in carrying out the risk oversight function as follows:

The full Board regularly evaluates and discusses risk, risk mitigation strategies and our internal control environment. Topics examined at this meeting include, but are not limited to, financial risks, political and regulatory risks, legal risks, information technology risks, economic risks and risks related to our productivity and reinvestment efforts. Because overseeing risk is an ongoing process and inherent in our strategic decisions, the Board also discusses risk throughout the year.

We believe that our Board leadership structure, previously discussed herein, supports the risk oversight function of the Board. We have an Executive Chairman, a Chief Executive Officer, a Lead Director and strong directors chair the various committees involved with risk oversight, there is open communication between management and directors and all directors are actively involved in the risk oversight function.

To learn more about risks facing us, you can review the factors included in Part 1, Item 1A. “Risk Factors” in the Form 10-K. The risks described in the Form 10-K are not the only risks facing the Company. Additional risks and uncertainties not currently known or that may currently be deemed to be immaterial also may materially adversely affect the Company’s business, financial condition or results of operations in future periods.

During fiscal 2017, risk areas of particular Board and committee focus included:

Our Director Nominations Process

Our Board is responsible for approving candidates for Board membership. The Board has delegated the screening and recruitment process to our Governance and Nominating Committee.

Criteria for Directors

Our Board believes that certain criteria should be met by director nominees to ensure effective corporate governance, support our strategies and businesses, account for individual director attributes and the effect of the overall mix of those attributes on the Board’s effectiveness, and support the successful recruitment of qualified candidates for the Board. Qualified candidates are those who, in the judgment of the Governance and Nominating Committee, possess certain personal attributes and a sufficient mix of experience and related attributes to assure effective service on the Board. The personal attributes of director nominees that the Governance and Nominating Committee considers include:

The Board prefers a mix of backgrounds and experiences among its members. The Board does not follow any ratio or formula to determine the appropriate mix. Rather, it uses its judgment to identify and determine nominees whose backgrounds, attributes and experiences, taken as a whole, will contribute to high standards of Board service.

Processes for Identifying Director Candidates

Our Governance and Nominating Committee has two principal methods for identifying potential Board candidates (other than those proposed by Shareholders, as discussed below). First, such Committee solicits ideas for possible candidates from a number of sources, including other members of the Board, senior executives, individuals personally known to Board members and research. Additionally, the Governance and Nominating Committee may, from time to time, use its authority under its charter to retain, at our expense, one or more search firms to identify candidates (and to approve such firms’ fees and other retention terms). The Governance and Nominating Committee did not retain a search firm during fiscal 2017.

Our Governance and Nominating Committee will also consider nominees recommended by Shareholders as candidates for Board membership. A Shareholder wishing to nominate a candidate for Board membership should provide written notice to the Governance and Nominating Committee in the care of the Secretary, Mercer International Inc., Suite 1120, 700 West Pender Street, Vancouver, B.C., Canada V6C 1G8. To nominate a candidate for election to the Board at an annual meeting, the notice must be received not less than 120 days before the first anniversary of the date of the Company’s Proxy Statement released to Shareholders in connection with the annual meeting held in the prior year. The notice should contain information about both the nominee and the Shareholder making the nomination, including such information regarding each nominee

required to be included in a proxy statement filed pursuant to SEC rules and regulations and such other information sufficient to allow the Governance and Nominating Committee to determine if the candidate meets the criteria for Board membership described above. The Governance and Nominating Committee may require that the proposed nominee furnish additional information to determine that person’s eligibility to serve as a director. All recommendations will be brought to the attention of the Governance and Nominating Committee.

Evaluation of Director Candidates

The Governance and Nominating Committee will consider and evaluate all candidates identified through the processes described above, including incumbents and candidates proposed by Shareholders.

If, based upon the Governance and Nominating Committee’s initial evaluation, the candidate continues to be of interest, members of the Committee will interview the candidate and communicate their evaluation to the rest of its members and the Executive Chairman and Chief Executive Officer. Additional meetings between the candidate and other members of the Governance and Nominating Committee and the Executive Chairman and Chief Executive Officer may also be arranged. Ultimately, background and reference checks will be conducted by the Governance and Nominating Committee.

As a result of its work and consideration of potential candidates, the Governance and Nominating Committee endeavors to maintain an evergreen list of potential candidates.

Recommendation and Nomination

After consideration, the Governance and Nominating Committee will finalize its list of recommended candidates to the Board for its consideration. Candidates who are then recommended by the Governance and Nominating Committee and approved by our Board are included in our recommended slate of director nominees in our proxy statement.

With Mr. Lauritzen and Ms. Orr electing not to stand for re-election at the Meeting, the Governance and Nominating Committee reviewed a number of potential candidates and members of the Committee and the CEO met several candidates personally, both formally and socially. Based upon such reviews and meetings, the Committee recommended and the Board unanimously approved the nomination of both

Mr. Wallace and Ms. Welty for election to the Board at the upcoming Meeting.

Potential Future Changes to Nomination Process

Our nomination policies are intended to provide a flexible set of guidelines for the effective functioning of our director nomination process. Our Governance and Nominating Committee reviews the nomination policy at least annually to consider and make such modifications as may be required to reflect our then needs and circumstances and to address any changes in applicable legal or listing standards. Our Governance and Nominating Committee may amend the nomination policy at any time, in which case the most current version will be available on our website.

Talent Management and Succession Planning

In light of the importance of executive leadership, we have a succession planning process which is held at least semi-annually. The process encompasses a broad group of managers and executives up to and including the Chief Executive Officer.

Our Compensation and Human Resources Committee, together with our Chief Executive Officer and assisted by our Lead Director, reviews our executive succession planning procedures, including management development activities. We generally strive to appoint our most senior executives from within. To this end, individuals who are identified as having potential for senior executive positions are evaluated by the Compensation and Human Resources Committee. The careers of such persons are monitored to ensure that, over time, they have appropriate exposure to our Board and interact with the Board in various ways, including through participation in certain Board meetings and other Board-related activities and meetings with individual directors, both in connection with director visits to our mills and otherwise. In addition, selected executives are provided with continuing management education through attendance at senior level educational programs, courses and seminars.

Director Education

New Director Education

Our new director orientation program covers our vision, strategies, risks, financial matters, internal controls, corporate governance practices and policies, succession planning and non-director compensation. As part of such orientation, new directors visit our mills to better understand our operations.

Continuing Education

Our continuing education program consists of regular visits to our operating facilities, meetings and social

engagements with our operating personnel, customer visits both in Europe and China and other meetings and visits on topical matters such as at research and development facilities. Most years, select directors, along with management representatives, attend meetings with customers and other market participants in China to broaden their understanding of this key market. We provide updates to our Board on relevant topics at meetings throughout the year. We also provide ongoing education to our directors through participation in the NYSE Board Program. We also reimburse directors who attend education programs and institutions for fees and related expenses.

Director Evaluation

Our Board annually reviews the effectiveness of the Board, its committees and individual directors as part

of its ongoing commitment to improve their oversight, guidance and review of senior management.

This evaluation process is conducted by our Governance and Nominating Committee, which conducts an annual evaluation of our Board, Board committees and directors. The evaluation also evaluates our Executive Chairman, CEO and Lead Director. The process is led by the Lead Director, who is also the Chair of the Governance and Nominating Committee. These evaluations help the Board develop priorities, form part of our assessment of the skills and competences needed by the Board to support our strategic objectives, consider potential director nominee candidates and refine our corporate governance practices.

Shareholder Communications with Board

Shareholders who wish to communicate with the Board (other than with respect to a complaint or concern regarding accounting, internal accounting controls or auditing matters which must be directed to the Audit Committee as described below) should send written correspondence to the Board in the care of the Secretary, Mercer International Inc., Suite 1120, 700 West Pender Street, Vancouver, B.C., Canada V6C 1G8. The correspondence should indicate that the person sending the correspondence is a Shareholder and set out the purpose of such communication. The secretary will: (i) forward the correspondence to the director to whom it is addressed or, in the case of correspondence addressed to the Board generally, to the Lead Director; (ii) attempt to handle the inquiry directly where it is a request for information about the Company; or (iii) not forward the correspondence if it is primarily commercial in nature or if it relates to an improper topic. All such correspondence will be summarized for the Board periodically, and each such correspondence will be made available to any director upon request.

Complaint Procedure

The Audit Committee has established procedures for: (i) the receipt, retention and treatment of complaints received by the Company regarding accounting, internal accounting controls or auditing matters; and (ii) the confidential and anonymous submission by the Company’s employees and others of concerns regarding questionable accounting or auditing matters. A person wishing to notify the Company of such a complaint or concern should send a written notice thereof, marked “Private & Confidential’’, to the Chair of the Audit Committee, Mercer International Inc., Suite 1120, 700 West Pender Street, Vancouver, B.C., Canada V6C 1G8.

Shareholding Guideline for Non-Employee Directors

We have a target shareholding guideline in place for our non-employee directors which provides each non-employee director should, within three years of becoming a director, own a minimum number of Shares which is equal in value to three times the amount of their annual cash retainer. As of the Record Date, all of our non-employee directors who have been directors for at least three years as of such date, including our Lead Director, met the guideline amount.

Review and Approval of Related Party Transactions

The Board recognizes that related party transactions can present a heightened risk of potential or actual

conflicts of interest and may create the appearance that decisions are based on considerations other than our and our Shareholders’ best interests. As a result, the Board prefers to avoid related party transactions. However, the Board recognizes that there are situations where related party transactions may be in, and not inconsistent with, our and our Shareholders’ best interests.

As a result, pursuant to our Governance Guidelines and its Charter, the Board has delegated to the Audit Committee responsibility for reviewing and approving the terms and conditions of all proposed transactions between us, any of our officers, directors or Shareholders who beneficially own more than 5% of our outstanding Shares, or relatives or affiliates of any such officers, directors or Shareholders, to ensure that such related party transactions are fair and are in our overall best interest and that of our Shareholders.

In the case of transactions with employees, a portion of the review authority is delegated to supervising employees pursuant to the terms of our Code of Business Conduct and Ethics.

The Audit Committee has not adopted any specific procedures for conduct of reviews and considers each transaction in light of the facts and circumstances. In the course of its review and approval of a transaction, the Audit Committee considers, among other factors it deems appropriate:

The Audit Committee has the authority to approve a related party transaction if the committee determines that the transaction is on terms that are not inconsistent with our and our Shareholders’ best interests.

Any member of the Audit Committee who is a related person with respect to a transaction under review may not participate in the deliberations or vote respecting approval or ratification of the transaction, provided, however, that such director may be counted in determining the presence of a quorum at a meeting of the committee that considers the transaction.

Our Audit Committee monitors and oversees our financial reporting process on behalf of our Board. Management has primary responsibility for our financial statements and the financial reporting process, including the Company’s system of internal controls.

The Audit Committee has met and held discussions with management and our independent registered public accounting firm, PricewaterhouseCoopers LLP, regarding the fair and complete presentation of our results and the assessment of our internal control over financial reporting. The Audit Committee has discussed significant accounting policies we applied in our financial statements, as well as alternative treatments. Management represented to the Audit Committee that our consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States, and the Audit Committee has reviewed and discussed the consolidated financial statements with management and PricewaterhouseCoopers LLP. The Audit Committee discussed with PricewaterhouseCoopers LLP the matters required to be discussed by Statement on Auditing Standards No. 61, as amended (AICPA, Professional Standards, Vol. 1 AU Section 380), as adopted by the Public Company Accounting Oversight Board in Rule 3200T.

In addition, the Audit Committee has discussed with PricewaterhouseCoopers LLP the registered public accounting firm’s independence from the Company and its management, including the matters in the written disclosures required by Independence

Standards Board Standard No. 1. The Audit Committee also has considered whether PricewaterhouseCoopers LLP’s provision of non-audit services to the Company is compatible with the registered public accounting firm’s independence. The Audit Committee has concluded that PricewaterhouseCoopers LLP is independent from the Company and its management.

The Audit Committee discussed with PricewaterhouseCoopers LLP the overall scope and plans for their respective audits. The Audit Committee met with PricewaterhouseCoopers LLP, with and without management present, to discuss the results of their examinations, the evaluations of our internal controls, and the overall quality of our financial reporting.

In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Board, and the Board approved, that the audited financial statements be included in the Form 10-K for filing with the SEC.

No member of the Compensation and Human Resources Committee is a current or former employee of the Company or has had any relationship requiring disclosure by the Company under the SEC’s rules requiring disclosure of certain relationships and related party transactions. None of our current executive officers has ever served as a

member of the board or compensation committee (or other board committee performing equivalent functions) of any other entity that has or has had one or more of its executive officers serve as a member of our Board or our Compensation and Human Resources Committee.

The Compensation and Human Resources Committee has the authority to engage independent compensation consultants. It has in the past and may in the future engage an outside consultant to assist the Committee in assessing the Company’s executive compensation programs. In 2017, in connection with its review of executive compensation, the Committee engaged Willis Towers Watson (“WTW”) as its compensation consultant. WTW was paid a fee of $33,531 for such consultation.

In furtherance of maintaining the independence of the committee’s compensation consultants, the committee has sole authority to retain, terminate and obtain the advice of any selected consultant. Additionally, the

committee’s consultant will not perform any services for management unless approved by the committee.

In 2017, WTW provided ongoing annual services in connection with the salaried pension plan for our Celgar mill and was paid $251,083 for such services. Such services are ongoing until terminated by us and have been provided by WTW for several years.

Based on the policies and procedures implemented by the Committee and by WTW to ensure the objectivity of WTW’s executive compensation consulting services, the Committee believes that the consulting advice it received from WTW is objective and not influenced by WTW’s other relationships with us.

Foreign Currency Compensation

All of the cash compensation, being primarily salary and annual bonuses, for our NEOs is paid in either euros (as to Messrs. Lee, Nossol and Ridder) or Canadian dollars (as to Messrs. Gandossi and Ure). Such amounts are then translated into dollars using the average Federal Reserve Bank of New York spot rate for the appropriate period. As a result, reported compensation amounts decline in periods when the dollar strengthens against the euro and Canadian dollar and conversely increase when the dollar declines versus such currencies.

Amounts reported in the “Executive Compensation Tables” are in dollars.

Timing of Executive Compensation Decisions

Our executive variable compensation decisions are generally made after the end of our fiscal year and when our financial statements for such year are finalized. Thus, in February 2018, the Committee approved bonuses and awards for fiscal 2017, together with fixed base salaries for 2018. During each year, the Committee monitors performance and evaluates comparison group compensation data which it uses to finalize awards and decisions made after the fiscal year end.

In this regard, it is important to note that the Summary Compensation Table appearing on page 41 and the Grants of Plan-Based Awards Table appearing on page 43 only reflect plan-based awards actually issued in fiscal 2018, which were based on fiscal 2017 performance.

Fiscal 2017 - Compensation Decisions

In 2017, we had very strong operating and financial performance, achieved record pulp, energy and chemical production and sales volumes, expanded our business and increased our quarterly cash dividend.

In fiscal 2017, we:

In accordance with our emphasis on pay for performance, fiscal 2017 compensation awarded to our NEOs reflected our overall strong operating and financial performance, improvements to liquidity and our balance sheet, expansion of our business and initiatives to improve our business through cost reduction measures and new capital projects. In making decisions on performance-based compensation for fiscal 2017, the Committee also weighed and considered our generally favorable performance against our Peer Group Companies (as hereinafter defined), the increase in our share price in

2017 compared to 2016 and the return of capital to shareholders pursuant to our regular quarterly dividends.

The Committee does not rely upon any predetermined formulas or limited set of criteria when it evaluates the performance of our NEOs, but rather focuses on individual objectives and their effects in respect of our overall goals.

Short-Term Annual Cash Bonuses. In making its compensation decisions regarding annual bonuses for our NEOs in respect of their fiscal 2017 performance, the Committee reviewed and considered:

Executive Chairman and Chief Executive Officer Performances. The Committee evaluated both Messrs. Lee’s and Gandossi’s achievement of their 2017 performance objectives and leadership roles and guidance in, among other things:

The bonuses paid to our NEOs in respect of fiscal 2017 reflect the Committee’s assessment of the individual and overall Company factors discussed above for such fiscal year. In respect of Mr. Ure, it also included the Committee’s re-assessment of his bonuses for prior years.

Incentive Equity Grants or Awards. Our 2010 Plan allows the Committee to grant equity awards to our NEOs in the form of options, stock appreciation rights, restricted stock, restricted stock rights, performance shares and performance share units.

In 2014, the Committee implemented a long-term incentive compensation program (the “LTIP”) which primarily provided for the granting of “performance stock units”, or “PSUs”, for our executives, including our NEOs.

Our PSUs vest after a three-year period and, as such, are designed to reward sustained performance over the period, rather than over a single year.

We grant our executives long-term performance based compensation, primarily in the form of PSUs. We believe PSUs incentivize executives to drive long-term performance, thereby aligning our executives’ interests with the long-term interest of Shareholders.

Although the value of PSUs is impacted by our Share price during the vesting period, PSUs serve to retain executives as they are generally perceived by the recipients as being more valuable than stock options.

Pursuant to the LTIP, we make annual grants of PSUs to our executives that vest based on the Committee’s assessment of the achievement of certain prescribed three-year performance criteria (the “Performance Criteria”) comprised of:

Each element is weighted equally. To incentivize performance, each component of Performance Criteria has a sliding scale so that an executive can achieve from 0% to 200% of the target award amount. See “Narrative Disclosure to Grants of Plan-Based Awards Table” on page 44 for a discussion of such Performance Criteria.

The Committee assesses such Performance Criteria based upon the audited financial statements of a completed three year performance period.

The Committee believes that: (i) having a multi-year performance period increases executive focus on long-term performance and better aligns the interests of our executives with our Shareholders; and (ii) the three components of Performance Criteria are important measures of our overall business performance.

The annual granting of PSUs ensures the continuity of these incentives, as the performance periods of PSUs granted in different years overlap and expired or vested awards are “replaced” each year with new grants. Each PSU is equivalent to one Share. As a result, the number of PSUs issued to executives was 200% of the target level, being the maximum amount of Shares that our executives may earn.

Vesting of 2015 PSUs

The three-year performance period for 436,420 PSUs (the “2015 PSUs”) awarded by the committee in 2014 to our executives, including our NEOs, ended on December 31, 2017.

In February 2018, the Board, based on the recommendation of the Committee, approved the vesting and awarding of 153,243 Shares to our executives (including our NEOs) pursuant to the 2015 PSUs. This vesting represents the Committee’s assessment of achievement against the three Performance Criteria as follows:

The vesting on a weighted basis was equal to 74% of the potential share award within a range of 0% to 200%.

Compensation Framework and Components

Our compensation framework for our NEOs is principally performance-based to support our overall business objectives and increase long-term Shareholder value. Our executive compensation program provides that a significant percentage of compensation awarded to our NEOs, especially our Executive Chairman and CEO, be variable, performance-based compensation and “at risk”.

We believe that it is appropriate for certain components of compensation to decline during periods of economic stress, reduced Operating EBITDA and earnings and significantly lower Share prices and to increase during periods of increased Operating EBITDA and earnings and higher Share prices.

We seek to accomplish our executive compensation objectives through an appropriate mix of short-term and long-term compensation, by providing a larger percentage of our executive officers’ total compensation opportunity in the form of equity compensation and by ensuring that a significant portion of our executive officers’ total pay opportunity is in the form of performance-based or at risk compensation.

In general, employees with more ability to directly influence overall business performance have a greater portion of:

Fixed vs. Performance-based Compensation. We believe our mix of fixed (primarily base salary) and and a significant weighting of performance-based compensation (primarily annual cash incentive bonuses and PSUs), supports our overall pay-for-performance culture and drives superior business performance. The percentage of an executive’s compensation opportunity that is performance-based, versus fixed, is based primarily on the employee’s role.

Short-term vs. Long-term Compensation. We believe our total compensation mix of short-term (primarily base salary and annual cash incentive bonuses) along with long-term (primarily PSUs) incentives, encourages focus on both long-term strategic objectives and shorter-term business objectives without excessive risk.

Cash vs. Equity Compensation. We believe our mix of cash (base salary and annual cash incentive bonuses) and equity (primarily PSUs) compensation, with a significant portion of each executive officer’s

total compensation opportunity coming through equity incentive grants, closely aligns the interests of our executive officers with those of our shareholders.

Compensation Components. To achieve our objectives, we use a mix of four compensation components, being base salary, annual incentive bonuses, long-term equity incentives and other perquisites intended to be competitive in the market.
