This year’s Annual Meeting will be conducted virtually, for the health and safety of our stockholders, management and Board, in light of public health concerns regarding the coronavirus (COVID-19) pandemic. Please do NOT travel to the Company’s corporate headquarters for the Annual Meeting.
How May I Participate in the Virtual Annual Meeting?
You may attend the virtual Annual Meeting, ask questions, and vote your shares during the Annual Meeting at https://web.lumiagm.com/297731529. If you are a stockholder of record as of March 1, 2021, the record date for the annual meeting, you should click on “I have a login,” enter the control number found on your proxy card you previously received, and enter the password “swm2021” ​(the password is case sensitive).
If your shares are held in “street name” through a broker, bank or other nominee, in order to participate in the virtual Annual Meeting you must first obtain a legal proxy from your broker, bank or other nominee reflecting the number of shares of the Company’s common stock, par value $0.10 per share (the “Common Stock”) you held as of the record date, your name and email address. You then must submit your legal proxy with a request for registration to American Stock Transfer & Trust Company: (1) by email to proxy@astfinancial.com; (2) by facsimile to 718-765-8730 or (3) by mail to American Stock Transfer & Trust Company, Attn: Proxy Tabulation Department, 6201 15th Avenue, Brooklyn, NY 11219.

TABLE OF CONTENTS
We currently are not aware of any business to be acted upon at the Annual Meeting other than that described in this Proxy Statement. If, however, other matters are properly brought before the Annual Meeting, or any adjournment or postponement of the Annual Meeting, your proxy includes discretionary authority on the part of the individuals appointed to vote your shares to act on those matters according to their best judgment.
Adjournment of the Annual Meeting may be made for the purpose of, among other things, soliciting additional proxies to obtain a quorum. Any adjournment may be made from time to time by the chairman of the Annual Meeting.
What Constitutes a Quorum for Purposes of the Annual Meeting?
A quorum for the Annual Meeting will be a majority of the issued and outstanding shares of the Company’s Common Stock, virtually present online or represented by proxy at the Annual Meeting. Abstentions and “broker non-votes” are counted as present for purposes of determining a quorum.
Can I Ask Questions at the Virtual Annual Meeting?
Yes. Stockholders as of the record date who properly log in and participate in our virtual Annual Meeting will have an opportunity to submit questions live via the Internet during a designated portion of the meeting. During the question and answer session, we intend to answer all questions submitted during the meeting which are pertinent to the Company and the meeting matters, as time permits.
What if I Don’t Have Internet Access?
Stockholders of record can call (833) 729-4775 (toll-free) or (830) 213-7699 (international) and use their control number to listen to the meeting proceedings. You will not be able to vote your shares during the Annual Meeting.
Who is Entitled to Vote at the Annual Meeting?
Each stockholder of record at the close of business on March 1, 2021, the record date for the Annual Meeting, will be entitled to one vote for each share registered in such stockholder’s name. As of March 1, 2021, there were 31,407,678 shares of Common Stock outstanding.
Participants in the Company’s Retirement Savings Plan (the “Plan”) may vote the number of shares they hold in that plan. The number of shares shown on a participant’s proxy card includes the stock units the participant holds in the Plan and serves as a voting instruction to the trustee of the Plan for the account in the participant’s name. Information as to the voting instructions given by individuals who are participants in the Plan will not be disclosed to the Company.
A list of stockholders entitled to vote at the Annual Meeting will be available to stockholders for examination 10 days prior to the Annual Meeting. To review the list of stockholders, please contact Investor Relations at investors@swmintl.com.
How May I Vote My Shares?
If you are a stockholder of record and hold your shares in your own name with our transfer agent, American Stock Transfer & Trust Company, you can vote by completing, signing, dating and mailing the enclosed proxy card to American Stock Transfer & Trust Company in the envelope provided. Proxy cards received prior to the Annual Meeting will be voted as instructed. You may also vote over the Internet until 11:59 p.m. Eastern Time the day before the Annual Meeting by following the instructions on the enclosed proxy card or you may vote during the virtual Annual Meeting.
If your shares are held in “street name” ​(i.e., if they are held through a broker, bank or other nominee), you may receive a separate voting instruction form with this Proxy Statement, or you may need to contact your broker, bank or other nominee to determine whether you will be able to vote electronically by using the Internet or by telephone prior to the Annual Meeting. If your shares are held in “street name” and you wish to vote online during the virtual Annual Meeting, you must obtain a legal proxy from the record holder

(the broker, bank or other nominee) giving you the right to vote your shares at the Annual Meeting. You may then participate in the Annual Meeting by following the instructions provided above under “How May I Participate in the Virtual Annual Meeting?”
If your vote is received before the Annual Meeting, the named proxies will vote your shares as you direct. If you return a validly executed proxy but do not make voting selections, your shares will be voted in accordance with the Board’s recommendations on each proposal, discussed below.
How Does the Board Recommend that I Vote?
The Board unanimously recommends that you vote:
•
FOR Proposal One — Election of the two nominees to the Board of Directors
​
•
FOR Proposal Two — Ratification of Deloitte & Touche LLP as the Company’s Independent Registered Public Accounting Firm for 2021; and
​
•
FOR Proposal Three — Non-Binding Advisory Vote to Approve Executive Compensation.
​
What Vote is Required to Approve Each Proposal?
Proposal One — Election of Directors. Directors will be elected by a plurality vote of shares of the Company’s Common Stock as of the record date virtually present in person or represented by proxy at the Annual Meeting and entitled to vote on the election of directors. This means that the individuals who receive the greatest number of votes cast “FOR” will be elected as directors, up to the maximum number of directors to be chosen at the meeting. Proxies cannot be voted for a greater number of persons than the number of nominees named in this Proxy Statement. Votes may be cast in favor of, or withheld from, each nominee. Votes that are withheld will be excluded entirely from the vote and will have no effect.
Proposal Two — Ratification of the Selection of the Independent Registered Public Accounting Firm. The vote will be decided by the affirmative vote of a majority of shares of the Common Stock as of the record date virtually present in person or represented by proxy and entitled to vote on the subject matter.
Proposal Three — Non-Binding Advisory Vote to Approve Executive Compensation. The vote will be decided by the affirmative vote of a majority of shares of the Common Stock as of the record date virtually present in person or represented by proxy and entitled to vote on the subject matter. This is an advisory vote and is not binding on the Board of Directors. However, the Compensation Committee and the Board of Directors expect to take into account the outcome of the vote when considering future decisions regarding executive compensation.
What Happens if I Do Not Vote My Shares?
We encourage you to vote. Voting is an important stockholder right and helps to establish a quorum for the conduct of business. Abstentions and “broker non-votes” are counted as present and entitled to vote for purposes of determining a quorum. In tabulating the voting result for any particular proposal, abstentions and, if applicable, broker non-votes are not counted as votes “FOR” or “AGAINST” ​(or “WITHHOLD” for) the proposals. Accordingly, abstentions will have no effect on Proposal One, since only votes “FOR” a director nominee will be considered in determining the outcome. Because they are considered to be present and entitled to vote for purposes of determining voting results, abstentions will have the effect of a vote “AGAINST” Proposals Two and Three.
Under the New York Stock Exchange (“NYSE”) rules, if your shares are held in “street name” and you do not indicate how you wish to vote, your broker is permitted to exercise its discretion to vote your shares only on certain “routine” matters. Proposal Two is a “routine” matter under NYSE rules and, as such, your broker is permitted to exercise discretionary voting authority to vote your shares “FOR” or “AGAINST” the proposal in the absence of your instruction. The other proposals are not considered “routine” matters. Accordingly, if you do not direct your broker how to vote on such proposals, your broker may not exercise discretionary voting authority and may not vote your shares. This is called a “broker non-vote,” and although your shares will be considered to be represented by proxy at the Annual Meeting and counted for quorum purposes as discussed above, they are not considered to be shares “entitled to vote” on those proposals

TABLE OF CONTENTS
and will not be counted as having been voted on the applicable proposals. Therefore, they will not have the effect of a vote for or against (or withheld from) such proposals.
How Can I Revoke My Proxy or Change My Vote?
At any time before it is voted, any proxy may be revoked by the stockholder who granted it by (i) delivering to the Company’s EVP, General Counsel and Secretary at the Company’s principal executive office another signed proxy card or a signed document revoking the earlier proxy or (ii) voting online during the virtual Annual Meeting. You may also change your previously submitted vote by submitting a subsequent vote over the Internet prior to the Annual Meeting. The last vote received prior to the Annual Meeting will be the one counted.
If your shares are held in “street name” ​(i.e., if they are held through a broker, bank or other nominee), you may submit new voting instructions by contacting your broker, bank or other nominee. At any time before your previously submitted vote or previously granted proxy is voted, you may change such vote or revoke such proxy online during the Annual Meeting if you obtain a legal proxy from the record holder (the broker, bank or other nominee) giving you the right to vote the shares and have followed the instructions to participate in the meeting provided above under “How May I Participate in the Virtual Annual Meeting?”
Who Pays for the Proxy Solicitation?
The Company has engaged the firm of Georgeson LLC, to assist in distributing and soliciting proxies for a fee of approximately $11,500, plus reasonable out-of-pocket expenses. However, the proxy solicitor fee is only a small fraction of the total cost of the proxy process. A significant expense in the proxy process is printing and mailing the proxy materials. The Company will reimburse brokers, fiduciaries and other nominees for their reasonable expenses in forwarding proxy materials to beneficial owners. In addition to solicitation by mail, directors, officers and employees of the Company may solicit proxies in person, by telephone or by other means of communication. Directors, officers and employees of the Company will not receive any additional compensation in connection with such solicitation. The Company will pay the entire cost of the proxy solicitation.
Who Will Count the Vote?
American Stock Transfer & Trust Company has been engaged to tabulate stockholder votes and act as our independent inspector of election for the Annual Meeting.
Who Can Help Answer Any Other Questions I Might Have?
If you have any questions concerning the virtual Annual Meeting (including accessing the meeting by virtual means) or would like additional copies of the Proxy Statement or need help voting your shares of Common Stock, please contact our transfer agent: American Stock Transfer & Trust Company, at help@astfinancial.com or call the Shareholder Services Department at 1 (800) 937-5449 or (718) 921-8124.

Either directly or through deferred compensation accounts, each director must hold

As of the date of this Proxy Statement, all directors and Named Executive Officers have met or, within the applicable period, are expected to meet, these stock ownership guidelines.
The following table sets forth information as of March 1, 2021 regarding the number of shares of Common Stock beneficially owned by all directors and nominees, by each Named Executive Officer and by all directors and executive officers as a group.

Hedging is defined in the policy to include any instrument or transaction, including put options and forward-sale contracts, through which such director or key executive would offset or reduce exposure to the risk of price fluctuations in the Company’s stock. In addition, the Company strongly discourages all other employees from engaging in similar arrangements with respect to Company stock, and any employee who wishes to enter into such an arrangement must seek prior approval from our General Counsel.
The policy also generally prohibits all officers, directors and employees of the Company (and its subsidiaries, independent contractors or consultants) from, among other things, engaging in short sales or transactions in publicly traded options, puts, calls or other derivative securities based on the Company’s equity securities on an exchange or any other organized market.
Delinquent Section 16(a) Reports
Section 16(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), requires the Company’s directors and executive officers and persons who own more than 10% of a registered class of the Company’s equity securities to file reports with the SEC regarding beneficial ownership of Common Stock and other equity securities of the Company. Directors, executive officers and greater than 10% stockholders are required by SEC regulations to furnish the Company with copies of all forms they file pursuant to Section 16(a).
Based solely on a review of copies of such reports filed with the SEC and written representations from the Company’s directors and executives that no other reports were required, the Company believes that all of its directors, executive officers and greater than 10% stockholders complied with the reporting requirements of Section 16(a) applicable to them since January 1, 2020, other than one Form 4 for Dr. Ritrievi to report an acquisition of 1,000 shares of Common Stock.

Overview of Our Nominees and Continuing Directors
Board Structure
The Company’s By-Laws provide that the number of directors on its Board shall be fixed by resolution of the Board from time to time and, until otherwise determined, shall not be less than six nor more than twelve. The Board presently has eight members. The Board is divided into three classes of directors of the same or nearly the same number. The table below shows the allocation of our directors and nominees across the three classes:

​ | Class I – Current Term Ending at 2023 Annual Meeting | ​ | ​ | Class II – Nominees for Election at 2021 Annual Meeting | ​ | ​ | Class III – Current Term Ending at 2022 Annual Meeting | ​

​ | Marco Levi | ​ | ​ | Kimberly E. Ritrievi, ScD | ​ | ​ | Jeffrey Kramer, PhD | ​
​ | Mark L. Bye | ​ | ​ | ​ | ​ | ​ | Anderson D. Warlick | ​

Board Succession Planning
The Board, through its Nominating & Governance Committee, regularly reviews the particular skill sets required by the Board based on the nature of the Company’s business, strategic plans and regulatory challenges as well as the current performance of the incumbent directors. The Nominating & Governance Committee expects to continue to seek director candidates to replace current directors as they retire.
The By-Laws of the Company provide that a director is not eligible for election or re-election after his or her 72nd birthday but allow the Board to make an exception to this policy when it believes that nomination is in the best interests of the Company’s stockholders.
Nominees for Director
Upon recommendation of the Nominating & Governance Committee, the Board has nominated Mr. John D. Rogers and Dr. Kimberly E. Ritrievi for election to the Board as Class II directors to serve a three-year term ending at the 2024 Annual Meeting of Stockholders. If elected by our stockholders, Mr. Rogers and Dr. Ritrievi will hold office until his or her successor has been elected and qualified or until the director’s earlier resignation or removal. Mr. Rogers and Dr. Ritrievi are current members of the Board.
The Board has determined that Mr. Rogers and Dr. Ritrievi are independent pursuant to the independence standards of the SEC, the NYSE and the Company. Each nominee for director has consented to serve if elected. Should the nominees become unable to serve, proxies may be voted for another person designated by the Board. Proxies can only be voted for the number of persons named as nominees in this Proxy Statement.
Board Recommendation
The Board of Directors unanimously recommends a vote FOR the election to the Board of each of the two nominees for director.

12

TABLE OF CONTENTS
includes an assessment of the person’s judgment, experience, financial expertise, independence, understanding of the Company’s business or other related industries, commitment and availability to prepare for and attend Board and Standing Committee meetings and such other factors as the Nominating & Governance Committee determines are relevant in light of the needs of the Board and the Company. In seeking director candidates, the Nominating & Governance Committee uses a director candidate qualification matrix that compares the skills, experience, and competencies of existing directors, directors that are expected to retire in the near-term and the anticipated future strategic and operational strategies and development needs of the Company in order to identify skills, experience and/or competencies that may otherwise be absent from the Board’s future composition. It also uses its and the Board’s professional contact networks and/or director search firms to identify and recommend to the Board suitable director candidates.
The Nominating & Governance Committee selects qualified candidates consistent with criteria approved by the Board and presents them to the full Board, which decides whether to nominate the candidate for election to the Board. The Nominating & Governance Committee Charter authorizes the Nominating & Governance Committee to retain such outside experts, at the Company’s expense, as it deems necessary and appropriate to assist it in the execution of its duties. The Nominating & Governance Committee evaluates candidates recommended by stockholders in the same manner as it evaluates other candidates. A further discussion of the process for stockholder nominations and recommendations of director candidates is found under the caption “How Stockholders May Nominate or Recommend Director Candidates.”
Board Diversity
The Nominating & Governance Committee, with input from the Board, considers a wide range of factors in determining the desired experiences and qualifications for director candidates and then seeks candidates that best meet those criteria. The Company does not have a formal policy concerning the diversity of its directors, however, the diversity of the Board is a consideration in evaluating candidates for the Board.
How Stockholders May Nominate or Recommend Director Candidates
Any stockholder of record entitled to vote generally in the election of directors may nominate one or more persons for election as directors by complying with the procedures set forth in the Company’s By-Laws, a copy of which may be obtained from the Company’s EVP, General Counsel and Secretary. The notice of intent to nominate a candidate for the Board must satisfy the requirements described in the By-Laws and be received by the Company not less than 90 calendar days nor more than 120 calendar days before the first anniversary date of the preceding year’s annual meeting. The Company may require any proposed nominee to furnish such other information as may reasonably be required by the Company to determine the eligibility of such proposed nominee to serve as a director of the Company.
Stockholders may recommend a director candidate for consideration by the Nominating & Governance Committee by notifying the Company’s EVP, General Counsel and Secretary in writing at Schweitzer-Mauduit International, Inc., 100 North Point Center East, Suite 600, Alpharetta, Georgia 30022. The information that must be included in the notice and the procedures that must be followed (including the timeframe for submission) by a stockholder wishing to recommend a director candidate for the Nominating & Governance Committee’s consideration are the same as would be required under the By-Laws if the stockholder wished to nominate that candidate directly.

Executive Summary
Like many companies, our business has been significantly impacted by the COVID-19 pandemic, including due to reduced sales resulting from the shutdowns of some of the Company’s largest customers, such as auto manufacturers, and the temporary closure of our operating plants in France and New York. We also worked on reduced operating capacity as a result of safeguards instituted to keep our employees safe as we continued to serve our customers, including those customers in essential industries.
In fiscal 2020, adjusted earnings per share, net sales and operating profit, which are the metrics used for calculating performance under the Company’s 2020 annual incentive program, and adjusted EBITDA, which is the metric used for calculating performance under the Company’s 2020 performance share awards, were each significantly impacted by COVID-19. The Company’s performance goals were set in February 2020, prior to the time when we could have anticipated or known the impact of the impending COVID-19 pandemic. As a result and as described in more detail below, the Committee has given consideration to recognize and reward the exceptional performance achieved during 2020 despite the associated challenges and to reward operating decisions that were made in order to protect our employees and minimize plant disruptions to continue serving our customers
Executive Compensation Philosophy
The Compensation Committee of the Board (the “Committee”), which is responsible for overseeing the Company’s executive compensation program, believes that the Company’s executive compensation program should reward actions and behaviors that build a foundation for the long-term performance of the Company, while also rewarding the achievement of short-term performance goals informed by the Company’s strategy. To align the Company’s executive compensation program with the Committee’s compensation philosophy, the Committee has adopted the following objectives and guiding principles:

​ | Objectives | ​ | ​ | • Pay-for-performance ​ • Align performance goals and executive compensation with stockholder interests ​ • Total target compensation set within a range of market median value for like skills and responsibilities to attract, retain and motivate executive officers ​ | ​

14

TABLE OF CONTENTS

​ | Guiding Principles | ​ | ​ | • Allocate a significant portion of total target compensation to incentive-based compensation opportunities ​ • Set incentive plan objectives that the Committee believes contribute to increased stockholder value ​ • Award a significant portion of total compensation opportunity in the form of equity ​ • Utilize an annual competitive compensation study to guide decisions regarding total and individual compensation components and values ​ • Require executive officers to acquire and hold a significant equity interest in the Company within five years after joining the Company ​ | ​

2020 “Say on Pay”: Advisory Votes on Executive Compensation and Stockholder Engagement
In 2020, in a non-binding advisory vote, the Board asked the Company’s stockholders to indicate whether they approved the Company’s compensation program for the Company’s Named Executive Officers, as disclosed in the 2020 proxy statement (“say on pay”). At the 2020 Annual Meeting of Stockholders, stockholders approved the compensation program for the Company’s Named Executive Officers with approximately 98% of the votes cast in favor of the say on pay proposal.
The Committee’s review of the Company’s executive compensation program considers whether the program serves the interests of stockholders. The Committee carefully considers continuing and constructive stockholder feedback, and the Company routinely engages with stockholders to discuss topics including compensation disclosure, performance measures, and corporate governance matters. The Company intends to continue to engage with stockholders in the future to monitor, maintain, and modify its executive compensation program as it deems appropriate. Stockholders are invited to express their views or concerns directly to the Committee or the Board in the manner described below under “Communicating with the Board.”
Recent Modifications to Executive Compensation Program
As part of its ongoing review of the Company’s executive compensation program, and based on input from the Committee’s compensation consultant, the Committee determined that several compensation program changes would be implemented in 2020. Accordingly, in February 2020, the Committee approved the following changes to the Company’s executive compensation program:
•
Extended Performance Period for Performance Share Awards. Prior to 2020, the Company’s performance share awards were subject to a one-year performance period, with 50% of the earned shares subject to service-based vesting on each of the first and second anniversaries of the Committee’s certification of performance. During stockholder engagement, the Company’s stockholders expressed a desire for a longer performance period with respect to the Company’s performance share awards in order to further align the incentive program with the Company’s longer-term business results. Based on such feedback, beginning in 2020, performance share awards will be granted with a two-year performance period, followed by a one-year service-based vesting period. Under this design, the entire award is subject to a full three-years of stock price fluctuations. In order to accommodate the change in vesting schedule, since the prior design would have resulted in a portion of the award vesting shortly after the second anniversary of the grant date, the Committee included a one-time “gap” performance share award as part of the 2020 performance share awards, with such gap award subject to a one-year performance period followed by a one-year service-based vesting period.
​
•
Relative Performance Goal. Historically, the performance-based components of the Company’s executive compensation program have vested based on the achievement of absolute performance goals, which provide the primary links between incentive compensation and the Company’s strategic operating plan and financial results. Beginning with the 2020 performance share awards, the Company is incorporating a relative performance goal with a total stockholder return (“TSR”) modifier. Under this design, the vesting level for the performance share awards is subject to a 15% vesting
​
15

TABLE OF CONTENTS
modifier based on the Company’s TSR performance relative to the S&P SmallCap 600 Materials Index over the two-year performance period, with the vesting level increasing by 15% for relative TSR in the top 20% of the index and the vesting level decreasing by 15% for relative TSR in the bottom 20% of the index.
•
Clawback Policy. The Committee adopted a compensation clawback policy allowing the Company to recover incentive compensation paid to certain officers (including the Named Executive Officers), within three years following payment or vesting, in the event of certain financial statement restatements, including if the Company concludes that the officer committed a significant legal or compliance violation that contributed to the restatement.
​
Chief Executive Officer Compensation
In 2020, the Committee increased Dr. Kramer’s base salary to $800,000 (from $749,000 in 2019) in order to further align his compensation with the compensation peer group, while Dr. Kramer’s 2020 target annual incentive opportunity (as a percentage of base salary) remained at 100%, which was unchanged from the level established when he joined the Company in 2017.
In February 2020, the Committee granted Dr. Kramer a long-term incentive award opportunity for the 2020-2021 performance period under the Company’s 2015 Long Term Incentive Plan (the “2015 LTIP”). The grant value was allocated 65% to performance shares and 35% to service-based restricted stock. The Committee determined that it was desirable for a higher percentage of Dr. Kramer’s compensation to be equity-based and “at-risk” and, accordingly, elected to deliver the majority of his 2020 compensation increases in the form of increased target LTIP opportunity (2020 target LTIP opportunity, as a percentage of base salary, was 300% compared to 270% in 2019). In determining the increase, the Committee noted that Dr. Kramer’s target total direct compensation was below the competitive market as reported by Willis Towers Watson, the Committee’s independent compensation consultant, and concluded that the increase was necessary and prudent in order to further align Dr. Kramer’s target total direct compensation with the competitive median. In addition, in February 2020, the Committee granted Dr. Kramer a one-time “gap” performance share award, which, as described above, is subject to a one-year performance period followed by a one-year service-based vesting period. Dr. Kramer’s target opportunity with respect to the one-time “gap” award, as a percentage of base salary, was 97.5% and was intended to replicate the timing of the compensation he would have received if the Company had not changed the structure of its long-term incentive program, as described above. The Committee weighted the majority of Dr. Kramer’s 2020 compensation toward performance-based and at-risk pay over fixed pay in order to link a significant portion of Dr. Kramer’s compensation with the Company’s performance.
The following chart illustrates the Company’s executive compensation philosophy as it relates to the Chief Executive Officer and demonstrates the significant weighting of the Chief Executive Officer’s compensation toward at-risk pay.

Key Compensation Policies and Practices
We are committed to having strong governance standards with respect to our executive compensation program, policies and practices. Consistent with this focus, we maintain the following policies and practices that we believe demonstrate our commitment to executive compensation best practices.

​ | What We Do: | ​
​ | ✓ | ​ | ​ | Pay-for-performance. A significant portion of the Named Executive Officers’ compensation is delivered in the form of variable compensation that is connected to actual performance. For 2020, variable compensation comprised approximately 80% of the targeted annual direct compensation for Dr. Kramer and, on average, 61% of the targeted annual direct compensation for the other continuing Named Executive Officers, in each case, excluding the one-time “gap” performance share awards granted to each Named Executive Officer and the new hire compensation granted to Mr. Hoek in connection with his commencement of employment with the Company. | ​
​ | ✓ | ​ | ​ | Linkage between quantitative performance measures and operating objectives. Performance measures for incentive compensation are linked to operating objectives informed by our business strategy and designed to create long-term stockholder value. | ​
​ | ✓ | ​ | ​ | “Double trigger” in the event of a change-in-control. For all of our Named Executive Officers, in the event of a change-in-control, equity awards will accelerate upon a “double trigger” — meaning that both a change in control and qualifying termination of employment must occur for automatic acceleration. | ​
​ | ✓ | ​ | ​ | Independent compensation consultant. The Committee retains its own compensation consultant to review the Company’s executive compensation program and practices. | ​
​ | ✓ | ​ | ​ | Stock ownership guidelines. The Company’s Chief Executive Officer is required to hold stock equal to a multiple of five times his base salary, and each of the Company’s other continuing Named Executive Officers is required to hold stock equal to a multiple of three times his base salary. | ​
​ | ✓ | ​ | ​ | Annual risk assessment. Based on our annual risk assessment, we have concluded that our compensation program does not present a risk that is reasonably likely to have a material adverse effect on the Company. | ​
​ | ✓ | ​ | ​ | Annual peer group review. The Committee, with the assistance of its independent compensation consultant, annually reviews the composition of the peer group used to evaluate and assess the Company’s executive compensation program and makes adjustments to the composition of the group as it deems appropriate. | ​
​ | ✓ | ​ | ​ | Multi-year performance period. Performance share awards are subject to two-year performance periods (with full vesting on the one-year anniversary of the Committee’s certification of performance), excluding the one-time “gap” performance share awards granted to each Named Executive Officer during 2020. | ​
​ | ✓ | ​ | ​ | TSR modifier. Performance share awards are subject to a +/- 15% vesting modifier based on the Company’s relative TSR performance over a two-year performance period. | ​
​ | ✓ | ​ | ​ | Clawback policy. In 2020, the Committee adopted a compensation clawback policy allowing the Company to recover incentive compensation paid to certain officers (including the Named Executive Officers) in the event of certain financial statement restatements. | ​

​ | What We Don’t Do: | ​
​ | × | ​ | ​ | No change-in-control tax gross-ups. | ​
​ | × | ​ | ​ | The Company does not re-price stock options or buy-back equity grants. | ​
​ | × | ​ | ​ | The Company does not allow directors and key executives (including all Named Executive Officers) to hedge or pledge their Company securities. | ​

Elements of the 2020 Executive Compensation Program
The graphic below summarizes the material elements of the Company’s 2020 executive compensation program for the Company’s Named Executive Officers. The Committee believes that the design of the Company’s executive compensation program balances fixed and variable compensation elements, provides alignment with the Company’s short and long-term financial and strategic priorities through the annual and long-term incentive programs, and provides alignment with stockholder interests.

A significant percentage of the Named Executive Officers’ total target compensation was incentive-based, delivered in the forms of annual cash incentive awards and performance shares. The Committee believes that annual cash incentives and performance shares reward achievement of key drivers of stockholder value measurements, including earnings per share, EBITDA, net sales, operating profit and total shareholder return. The following charts illustrate the mix of the targeted annual direct compensation for the Chief Executive Officer and the average targeted annual direct compensation for the other continuing Named Executive Officers, and the portion of that compensation that is at-risk. For purposes of these charts, the percentage of targeted annual direct compensation was determined based on the annual base salary and target incentive opportunities applicable to the Named Executive Officers as of December 31, 2020 and these charts exclude the one-time “gap” performance share awards granted to each Named Executive Officer and the new hire compensation granted to Mr. Hoek in connection with his commencement of employment with the Company.

Base Salary
In October 2019, based on the compensation analysis performed by Willis Towers Watson as well as individual performance, for 2020, the Committee increased the base salaries for all of the then-serving Named Executive Officers. Mr. Hoek’s base salary was established when he joined the Company based on the competitive market as well as the Company’s historical compensation practices.
The following table shows the annual base salary for each Named Executive Officer for 2020 and 2019:

Name | ​ | ​ | 2020 Annual Base Salary | ​ | ​ | 2019 Annual Base Salary | ​

Daniel Lister(2) | ​ | ​ | ​ | $ | 460,793 | ​ | ​ | ​ | ​ | $ | 446,505 | ​ | ​

​

Mr. Hoek’s compensation was paid in Euros, and his 2020 base salary was converted at the December 31, 2020 exchange rate of 1.227 Euros to the U.S. dollar. Mr. Hoek joined the Company on January 1, 2020 and did not have an annual base salary in 2019.

Mr. Lister resigned from the Company, effective August 14, 2020. The 2020 salary amount reflects his annualized base salary level.
​
2020 Annual Incentive Program
Each year, each Named Executive Officer is provided with a cash-based award opportunity that may be earned if performance objectives are achieved over the fiscal year, with potential payout ranging from 0% to 200% depending on performance. Annual incentive compensation is intended to reward the performance of executive officers based on the attainment of the Company’s objectives. The 2020 target annual incentive opportunities (as a percentage of base salary) for the Named Executive Officers remained at the same levels that were established for 2019.
The Committee-approved corporate and business unit objectives, as applicable, for the Named Executive Officers are set out below, with the weighting of each component of the Named Executive Officers’ annual incentive opportunities reflecting their differing responsibilities and opportunities to affect business outcomes.
The 2020 performance objectives were selected because they were deemed by the Committee to be the primary drivers for delivering increased stockholder value. These performance objectives were established after considering economic conditions affecting the legacy tobacco-related business, the Company’s prior year performance, and the Company’s internal long-term operating plan. The Committee believed at the time that the performance targets were rigorous yet achievable, and therefore established the targets so that they would be achieved, at the target performance level, if the Company successfully executed against its operating plan for 2020. Because these targets were set in February 2020, these targets were set prior to the time when the Company could have anticipated or known the impact of the impending COVID-19 pandemic.

Earnings per share is diluted earnings per share from continuing operations at the consolidated level, adjusted to reflect items included in the Company’s approved budget. To the extent not reflected in such budget, it excludes restructuring-related expenses and charges, purchase price accounting amortization, accretion of a specified earnout liability, the impact of future stock buybacks, unusual and non-recurring items determined in accordance with U.S. generally accepted accounting principles, and other adjustments consistent with the Company’s past practice as approved by the Committee and calculated using budgeted foreign exchange rates as reflected in the Company’s financial records. During 2020, the Committee modified the earnings per share performance metric to increase the required performance goals to reflect additional earnings per share attributable to Tekra, LLC and Trient, LLC, acquisitions (the “Tekra and Trient Acquisitions”) that occurred during 2020. Prior to the adjustments, the earnings per share performance goals were as follows: Threshold — $3.35; Target — $3.64; Outstanding — $3.79; and Maximum — $3.93.

​
Following the conclusion of the 2020 performance year and in accordance with the adjustment provisions approved at the time the Committee established the 2020 annual incentive performance targets, the Committee determined to adjust the performance results to partially exclude certain costs incurred as a result of the COVID-19 pandemic. Accordingly, in determining results, the Committee excluded the unanticipated costs associated with: (i) additional spending on personal protective equipment and additional sanitation supplies; (ii) special bonuses paid to employees at our operating facilities in order to minimize plant shutdowns, particularly with respect to essential goods in the filtration business; (iii) additional customer freight expenses associated with expedited shipping required to accommodate our customer needs and which were driven by reduced shifts for safety reasons and government mandated plant closures; and (iv) costs incurred to perform additional sanitization procedures between shifts, the cost of moving equipment from sites shut down by government mandated closures to other operating facilities and increased costs for sourcing raw materials as a result of traditional sources being impacted by mandated government shutdowns (the costs described in clauses (i)-(iv), the “Excluded Costs”). While the Committee elected to adjust results to reflect the impact of the COVID-19 pandemic, it did so on a partial basis as it did not make any adjustments to reflect the loss of sales associated with plant shutdowns, including an eight week shutdown at our Ancram, New York facility. In addition, the Committee did not adjust results to account for reduced sales resulting from the shutdowns of some of the Company’s largest customers, such as auto manufacturers. The Committee determined that the adjustments noted above were consistent with the terms of the approved annual incentive program and were appropriate in order to recognize and reward the exceptional performance achieved during 2020 despite the associated challenges and to reward operating decisions that were made in order to protect our employees and minimize plant disruptions, particularly with respect to products that were deemed to be essential goods.
Based on the adjustment items noted above, the Company’s 2020 annual incentive program results, including a comparison to the applicable targets, were as follows:

2020 Long-Term Incentive Compensation
In February 2020, the Committee granted our Named Executive Officers long-term incentive award opportunities for the 2020-2021 performance period under the 2015 LTIP. Once the long-term incentive award opportunity was set for each Named Executive Officer, the grant value was allocated 65% to performance shares and 35% to service-based restricted stock (excluding the one-time “gap” performance share awards described below). Once the long-term incentive award opportunity was set for each Named Executive Officer, 35% of the grant value was allocated to service-based restricted stock, with the remaining portion representing the target performance shares. Under the long-term incentive design, individual achievement may range from 0% to 200% of target. For performance in excess of target (100%), the performance shares are further adjusted to maintain the overall LTIP payout leverage as the service-based shares are fixed regardless of individual achievement even though performance in excess of target was intended to apply to the overall LTIP opportunity. The Committee believes that this design supports the Company’s pay-for-performance philosophy by tying a majority of the long-term incentive award opportunity to the achievement of a pre-established performance goal that supports the Company’s operating and strategic plan.

The target opportunity for the 2020 performance period was equal to 300% of base salary for Dr. Kramer and ranged from 75% – 130% for the other Named Executive Officers. In 2020, the Committee increased Dr. Kramer’s target opportunity, as a percentage of base salary, to 300% (from 270% in 2019), Mr. Wamser’s target opportunity, as a percentage of base salary, to 130% (from 110% in 2019), and the target opportunities for Messrs. Lister and Nuñez, as a percentage of base salary, to 85% (from 75% in 2019), in each case based on individual performance and/or in order to further align their total direct compensation with the market median. Mr. Hoek’s target opportunity, as a percentage of base salary, was established when he joined the Company based on the competitive market as well as the Company’s historical compensation practices.

2020 Performance Share Awards
The 2015 LTIP provides opportunities to earn performance shares based on achievement of performance objectives. As noted above, in 2020 the Company began granting performance share awards that are subject to a two-year performance period, with vesting based on the Company’s adjusted EBITDA performance during the performance period. The number of performance shares earned based on the Company’s adjusted EBITDA performance will be reduced by 15% if the Company’s TSR falls below the twentieth percentile of the S&P 600 Materials Index during the two-year performance period and will be increased by 15% if the Company’s TSR exceeds the eightieth percentile during the two-year performance period. To encourage retention over a three-year period, any performance shares earned during the performance period vest on the one-year anniversary of Committee certification of the achievement of the performance objectives, rather than immediately at the end of the two-year performance period. This vesting structure is designed to hold our Named Executive Officers accountable by subjecting a portion of the award to three full years of stock price fluctuation.
As with annual incentive compensation, objectives for the 2020-2021 performance period were established based on the Company’s prior year performance and the Company’s internal operating and strategic plan. The Committee also reviewed payout information for the last five years. The Committee believed at the time that the performance targets were rigorous yet achievable, and therefore established the targets so that they would be achieved, at the target performance level, if the Company successfully executed against its operating plan during the 2020-2021 performance period. Because these targets were set in February 2020, these targets were set prior to the time when the Company could have anticipated or known the impact of the impending COVID-19 pandemic. In addition, during 2020, the Committee modified the adjusted EBITDA performance metric to increase the required performance goals to reflect additional adjusted EBITDA attributable to the Tekra and Trient Acquisitions. The modified adjusted EBITDA performance metric was designed to be rigorous yet achievable with the coordinated, cross-functional focus and effort of the executives.

​
Following the conclusion of the 2020 performance year and in accordance with the provisions of the 2020 performance share awards, the Committee adjusted the Excluded Costs from the performance results for the 2020 portion of the 2020-2021 performance period to partially exclude the impact of the COVID-19 pandemic. Consistent with the Committee’s approach to adjusting the 2020 annual incentive performance targets described above, these adjustments represent only a partial adjustment to reflect certain costs incurred as a result of the COVID-19 pandemic, as they do not adjust for the loss of sales associated with plant shutdowns or reduced sales resulting from the shutdowns of some of the Company’s largest customers.
2020 Service-Based Restricted Stock Awards
Pursuant to the service-based component of the 2020 award opportunity, in February 2020, the Named Executive Officers were granted shares of restricted stock with respect to 35% of the 2020 annual equity awards (excluding the one-time “gap” awards described below), as set forth in the table below. For the Named Executive Officers other than Mr. Lister, one-half of the shares vested in February 2021, and subject to continued employment with the Company, the remaining half will vest in February 2022.

​
2020 One-Time “Gap” Performance Share Awards
As described above, in order to accommodate the change to the vesting schedule applicable to performance share awards due to the transition to annual grants with two-year performance periods, in February 2020, the Committee granted to each Named Executive Officer a one-time “gap” performance share award, with such gap award subject to a one-year performance period followed by a one-year service-based vesting period.
The table below sets forth the target award value, as of the date of grant, of the one-time “gap” performance share award received by each Named Executive Officer under our 2020 long-term incentive program, expressed (i) as a percentage of 2020 base salary and (ii) in dollars. The values of the one-time “gap” performance share awards were intended to replicate the timing of the compensation each Named Executive Officer would have received if the Company had not changed the structure of its long-term incentive program, as described above.

Targets are stated and results are measured against the budgeted exchange rate. During 2020, the Committee modified the performance metrics to increase the required performance goals to reflect additional adjusted EBITDA attributable to the Tekra and Trient Acquisitions that occurred during 2020. Prior to the adjustments, the adjusted EBITDA performance goals were as follows (in millions): Threshold — $191.8; Target — $208.5; Outstanding — $216.8; and Maximum — $225.2.
​
Following the conclusion of the 2020 performance year and in accordance with the provisions of the 2020 performance share awards, the Committee adjusted the Excluded Costs from the performance results for the 2020 one-time “gap” performance share awards to partially exclude the impact of the COVID-19 pandemic. Consistent with the Committee’s approach to adjusting the 2020 annual incentive performance targets described above, these adjustments represent only a partial adjustment to reflect certain costs incurred as a result of the COVID-19 pandemic, as they do not adjust for the loss of sales associated with plant shutdowns or reduced sales resulting from the shutdowns of some of the Company’s largest customers. If the Committee had adjusted the 2020 performance share awards to exclude all COVID-19 related costs and impacts, the actual attainment percentage with respect to the 2020 one-time “gap” performance share awards would have equaled 200% of target.
Based on the adjustment items noted above, the performance results for the 2020 one-time “gap” performance share awards, including a comparison to the adjusted EBITDA target, were as follows:

​ | ​ | ​ | Target 100% | ​ | ​ | Actual Performance | ​ | ​ | Attainment Percentage | ​
Adjusted EBITDA ($ millions) | ​ | ​ | ​ | $ | 216.8 | ​ | ​ | ​ | ​ | $ | 233.6 | ​ | ​ | ​ | ​ | ​ | 196.6% | ​ | ​

Based on the Company’s 2020 adjusted EBITDA performance, the Committee approved achievement at 196.6% of target. As a result, in February 2021, the Named Executive Officers other than Mr. Lister became eligible to receive the performance shares in the amounts set forth in the table below, with 100% vesting in February 2022, subject to their continued employment through the vesting date.

Named Executive Officer New Hire Compensation
Pursuant to the terms of his employment agreement and in connection with the commencement of his employment with the Company, in January 2020, Mr. Hoek was paid a sign-on bonus of €50,000 ($56,140, based on a December 31, 2019 exchange rate of 1.1228 Euros to the U.S. dollar), and received a grant of 7,000 shares of restricted stock, which will vest 50% on each of January 1, 2022 and 2024, subject to Mr. Hoek’s continued employment through the applicable vesting date. The terms of these new hire awards were determined after considering market data and the Company’s historical compensation practices as well as the compensation deemed necessary to induce Mr. Hoek to join the Company.
Stock Ownership Guidelines
The Company has adopted the Schweitzer-Mauduit International, Inc. Stock Ownership Guidelines (the “Guidelines”), which require the Company’s executive officers, including the continuing Named Executive Officers, to own shares of Company common stock with a fair market value equal to a multiple of base salary. The Guidelines are designed to align the interests of the Company’s executive officers with the long-term interests of the Company’s stockholders and to promote commitment to sound corporate governance. Under the Guidelines, the Named Executive Officers must retain at least 50% of vested shares of Company common stock and shares acquired pursuant to the exercise of an option (except for shares sold to pay required tax withholding and the exercise price for options) until the required ownership guideline levels have been achieved (and thereafter if required to maintain the required ownership levels). Our Named Executive Officers must satisfy the Guidelines within five years after becoming subject to the Guidelines. Under the Guidelines, the Company’s Chief Executive Officer is required to hold stock equal to a multiple of five times his base salary and each of the Company’s other continuing Named Executive Officers is required to hold stock equal to a multiple of three times his base salary. As of the record date, each of our continuing Named Executive Officers has either met (and continues to meet) the Guidelines or is progressing toward meeting the Guidelines within the required period.

​ | What Counts Toward the Guidelines | ​ | ​ | What Does Not Count Toward the Guidelines | ​
​ | ✓ Shares owned outright (including through vesting of equity awards) ​ | ​ | ​ | × Performance shares ​ | ​
​ | ✓ Shares owned directly by a spouse, domestic partner, or minor child ​ | ​ | ​ | × Service-based restricted stock ​ | ​
​ | ✓ Shares owned indirectly through beneficial trust ownership ​ | ​ | ​ | × Unvested stock options ​ | ​
​ | ✓ Vested shares or stock units held in any Company equity plan, retirement plan or similar Company plan ​ | ​ | ​ | ​ | ​

How We Make Compensation Decisions
Compensation Approval Process
The Committee is responsible for determining the compensation of our Chief Executive Officer and each of our other executive officers. In setting the compensation of our other executive officers, the Committee takes into account the Chief Executive Officer’s review of each executive officer’s performance and his recommendations with respect to their compensation. The following is a summary of the compensation approval process during the year. While annual compensation decisions are generally made in the Committee’s fall and winter meetings, the Committee meets at other times throughout the year as required to fulfill its oversight responsibility with respect to the Company’s executive compensation program.

​ | When Action is Taken | ​ | ​ | What Action Is Taken | ​
​ | Prior Year: October – November | ​ | ​ | • Chief Executive Officer meets with the Committee and the Committee’s independent compensation consultant to review the annual competitive compensation analysis ​ | ​
​ | ​ | ​ | ​ | • Committee’s independent compensation consultant advises the Committee regarding the composition of the compensation peer group and performs a competitive analysis of the Company’s executive compensation practices compared to the peer group ​ | ​
​ | ​ | ​ | ​ | • Independent compensation consultant prepares an executive compensation proposal for full Committee review ​ | ​
​ | ​ | ​ | ​ | • Committee discusses the executive compensation program and evaluates whether the elements of compensation for officers and key employees are competitive ​ | ​
​ | ​ | ​ | ​ | • Committee approves the executive officers’ base salaries for the upcoming year ​ | ​
​ | Current Year: February | ​ | ​ | • Committee reviews prior year performance of the Named Executive Officers, considering the input of the Chief Executive Officer for Named Executive Officers other than himself ​ | ​
​ | ​ | ​ | ​ | • Committee certifies prior year’s performance and determines incentive compensation payouts ​ | ​
​ | ​ | ​ | ​ | • Board discusses the current and upcoming year compensation for the Chief Executive Officer ​ | ​
​ | ​ | ​ | ​ | • Committee approves annual incentive targets, equity incentive plan targets, and performance-level objectives for the upcoming year ​ | ​

Independent Compensation Consultant
Until October 2020, Willis Towers Watson provided executive compensation consulting services to the Committee. With respect to 2020, Willis Towers Watson provided services related to the review of 2020 compensation adjustments, including a review of market data, awards under our long-term incentive program, the setting of performance goals in our incentive plans including the payout leverage for results above and below the target performance levels, an analysis of the relationship between the Company’s total direct pay relative to the competitive market, a review of trends and regulatory developments with respect to executive compensation, a review of our compensation peer group, and assistance with this Compensation Discussion & Analysis. Willis Towers Watson is retained by and reports to the Committee and, at the request of the Committee, participates in committee meetings. Willis Towers Watson did not provide any other services to the Company in 2020. The Committee reviewed the independence of Willis Towers Watson under the New York Stock Exchange and SEC rules and concluded that the work of Willis Towers Watson has not raised any conflict of interest.

TABLE OF CONTENTS
In October 2020, the Committee engaged Meridian Compensation Partners, LLC (“Meridian”) as its independent compensation consultant. With respect to 2020, Meridian advised with respect to the adjustments to the performance results for each of the annual incentive program, 2020 performance share awards and one-time “gap” performance share awards to reflect the impact of the COVID-19 pandemic, as described above. The Committee reviewed the independence of Meridian under the New York Stock Exchange and SEC rules and concluded that the work of Meridian has not raised any conflict of interest.
Market-Based Competitive Compensation Levels
During 2020, the Committee continued its philosophy of setting compensation within a range of the market median for each position, which experience has shown is the level at which the Company has been able to recruit and retain highly talented executives. Compensation paid to the executive team is based on competitive market data developed annually by Willis Towers Watson.
The competitive compensation analysis prepared by Willis Towers Watson in October 2019 for evaluating 2020 compensation was intended to reflect the scope of an executive’s responsibilities, experience in the position, and competitive market conditions. The October 2019 compensation analysis relied on published survey data and proxy statement data from a peer group of companies.
Published Survey Data
The main basis used for comparison in the October 2019 compensation analysis was the following published survey data compiled by Willis Towers Watson:
•
For U.S.-based Named Executive Officers: Willis Towers Watson’s 2019 General Industry Executive Compensation Survey Report and Mercer’s 2019 Executive Benchmark Database
​
•
For the Named Executive Officer based in Luxembourg: Willis Towers Watsons’s 2019 Belgium Executive Compensation Database
​
The survey data is used for all Company executives as the primary tool for market comparisons as this source provides larger sample sizes and more direct matching between positions. All published survey data was aged to a common date of July 1, 2020 using an annual aging factor of 3.0% per year.
Proxy Statement Peer Group
The October 2019 compensation analysis also relied on proxy statement data from a peer group of 16 companies to supplement the survey data discussed above. The Committee believes that the Company’s peer group should reflect the industries in which the Company potentially competes for business, executive talent and capital, as well as the Company’s significant international operations.
The peer group used for evaluating 2020 compensation decisions consisted of the companies below. This is the same peer group that was used for evaluating 2019 compensation decisions, with the exception of (i) the removal of KapStone Paper and Packaging Corporation, Multi-Color Corporation, OMNOVA Solutions Inc. and PH Glatfelter Company due to mergers and acquisitions activity and (ii) the addition of Ferro Corporation, H.B. Fuller Company, Kraton Corporation, Mercer International Inc. and Myers Industries, Inc. based on comparability of size and business attributes.

Data represents the Company’s projected revenues (including joint ventures) for 2019 at the time Willis Towers Watson compiled the data in October 2019.
​
The Committee considers 2020 target total direct compensation to be competitive if it falls with +/-20% of the market median. The analysis evaluates the following components:
•
base salary;
​
•
annual incentive bonus (assuming attainment of the target objective level, as a percentage of base salary);
​
•
target total cash compensation (base salary plus target level annual incentive);
​
•
long-term incentive compensation (assuming attainment of the target objective level); and
​
•
target total direct compensation, which is the sum of base salary plus annual incentive plus long-term incentive compensation at the target levels.
​
Risk Management
On an annual basis, the Committee reviews the risks associated with the Company’s executive compensation program and whether the program was reasonably likely to have a material adverse effect on the Company. The Committee concluded that the program design, metrics and objectives, taken as a whole and considered within the other financial control and approval processes in place at the Company, were not reasonably likely to have a material adverse effect on the Company.

2020 NON-QUALIFIED DEFERRED COMPENSATION
Although all of our U.S.-based Named Executive Officers are eligible to participate in the Deferred Compensation Plan, Dr. Kramer and Mr. Nuñez are our only Named Executive Officers who have elected to participate in such plan.

Company contributions to the Deferred Compensation Plan were 401(k) savings plan contributions that exceeded IRS limitations on qualified plan contributions and are included in the “All Other Compensation” column in the 2020 Summary Compensation Table.
​

Amounts in this column include the following amounts that were previously reported in the Summary Compensation Table as compensation for 2019 and 2018: Dr. Kramer — $512,003; and Mr. Nuñez — $54,430.
​
Eligible employees may elect to defer up to 25% of their annual salary and up to 50% of their incentive bonus to the Deferred Compensation Plan No. 2, a non-qualified deferred compensation plan established in 2005 to allow participants to defer receipt of compensation and payment of certain income taxes. Eligibility to participate in the Deferred Compensation Plan is limited to “management” and “highly compensated employees” as defined in the Employee Retirement Income Security Act of 1974, as amended. The Company may, with Committee approval, make cash contributions to a participant’s account in the Deferred Compensation Plan.
Amounts deferred into the Deferred Compensation Plan No. 2 by a participating officer, or contributed on the officer’s behalf by the Company, can be invested at the officer’s election in an account that tracks, but does not actually invest in, some of the fund elections available under the Company’s 401(k) savings plan. The participating officer bears the investment risk. The Company makes no guaranty as to the return of the principal amount of any funds deferred or of any income thereon. The funds remain subject to the Company’s creditors while in the Deferred Compensation Plan No. 2.
A participant may elect to receive payment of the vested amount credited to his or her deferral account under the Deferred Compensation Plan No. 2 based on a participant election of a single lump sum or three, five, or ten annual installments. No payments may commence in fewer than five years following the date of the deferral election, except for alternative distributions that may occur in certain defined circumstances including disability, death of participant, separation from service, change of control and unforeseeable emergency, as such terms are defined in the plan. Certain individuals, including plan participants who are Named Executive Officers, must defer distributions from the plan for six months following a separation from service.

TABLE OF CONTENTS
POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE OF CONTROL
On November 2, 2016, the Committee adopted and approved the Schweitzer-Mauduit International, Inc. 2016 Executive Severance Plan (the “2016 Plan”) for members of the Company’s senior executive team.
The 2016 Plan provides that in the event of termination of a participant’s employment with the Company or one of its participating subsidiaries or business units within two years after a change of control of the Company for any reason other than cause, retirement, disability or death, a participant will be entitled to salary and benefit continuation. A change of control is defined as the date as of which: (a) a third person, including a “group” as defined in Section 13(d)(3) of the Exchange Act, acquires actual or beneficial ownership of shares of the Company having 30% or more of the total number of votes that may be cast for the election of directors of the Company; or (b) as the result of any cash tender or exchange offer, merger or other business combination, sale of assets or contested election, or any combination of the foregoing transactions (a “Transaction”), the persons who were directors of the Company before the Transaction cease to constitute a majority of the board of directors of the Company or any successor to the Company.
In the event of a qualifying termination of employment in connection with a change of control as of December 31, 2020, the then-serving Named Executive Officers would generally have been entitled to receive:
i.
a cash payment in an amount equal to three times the highest annual compensation (base salary and annual incentive awards) paid or payable within the three-year period ending on the date of termination; and
​
ii.
welfare benefits (including, health and dental benefits) from the Company for a period of three years.
​
The payments to a participant employed by one of the Company’s non-United States subsidiaries or business units are subject to certain adjustments to take into account the differences between the respective compensation, benefit and pension plans and programs in the United States and the participant’s place of employment.
The 2016 Plan provides that any benefits triggered by a change of control are subject to an automatic reduction to avoid the imposition of excise taxes under Section 4999 of the Internal Revenue Code in the event such reduction would result in a better after-tax result for the executive.
Upon a change of control, all deferred compensation plan contributions that have been granted to a participant, but not yet vested as of December 31, 2020, vest automatically. Awards granted under the Company’s 2015 LTIP are subject to double trigger vesting upon a change of control — meaning that both a qualifying termination of employment and a change of control must occur prior to the accelerated vesting of such awards. Under the Company’s annual incentive program, in the event a participant is terminated without cause within two years following a change of control, the participant is entitled to payment of a pro rata portion of the incentive award at the target performance percentage, without regard to achievement of pre-established objectives.
The 2016 Plan also provides that if a Named Executive Officer’s employment with the Company or an affiliate terminates absent a change of control for a reason other than death, retirement, disability, voluntary resignation or cause, the Company will pay the Named Executive Officer an amount equal to a severance multiple determined by the Committee at the time the individual is selected for participation. In the case of Mr. Nuñez, this severance multiple equals one-half times base salary, in the case of Mr. Wamser, this severance multiple equals one times base salary, and in the case of Dr. Kramer, this severance multiple equals two times base salary, in each case, payable as a cash lump sum. The 2016 Plan also provides for the continuation of the Company’s welfare benefits for the number of years equal to the severance multiple. A participant cannot receive both this payment as well as compensation under the 2016 Plan’s change of control provisions. The continuing Named Executive Officers are also eligible to receive salary continuation in the event of death or disability. Disability pay is provided through a combination of Company-paid short-term disability benefits and insured long-term disability benefits in accordance with Company policy.
The Committee establishes the eligibility criteria for participation and, from time to time, designates key employees as participants in the 2016 Plan. Subject to certain conditions, the 2016 Plan may be amended or

terminated by resolution of the Board, but no such amendment or termination may be effective during the two-year period following a change of control of the Company without the consent of all participants.
The Company’s equity award agreements also include accelerated vesting provisions for a termination of employment (i) due to death, disability, or retirement (age 55, with at least five years of service to the Company and consent to retire provided by the Committee); (ii) without cause or due to good reason within 24 months following a “change in control” of the Company; or (iii) without cause not within such 24-month period. If the performance period with respect to a performance award is in process, then the award will (a) vest on a pro rata basis based on target performance in the event of death, disability, or termination of employment without cause or due to good reason within 24 months following a change in control; (b) vest on a pro rata basis based on actual performance for in-process performance periods in the case of retirement; or (c) be forfeited for a termination of employment for any other reason.
The maximum amounts payable upon termination pursuant to the 2016 Plan, assuming that a change of control of the Company and/or a qualifying termination of employment had occurred on December 31, 2020, are set forth in the following tables for all Named Executive Officers other than Mr. Lister and Mr. Hoek. Mr. Lister did not receive any separation benefits from the Company in connection with his resignation in August 2020. Mr. Hoek does not participate in the 2016 Plan and will be entitled to severance benefits as required by Luxembourg law.

TABLE OF CONTENTS
PAY RATIO
As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(u) of Regulation S-K, we are providing the following disclosure about the relationship of the median of the annual total compensation of our employees to the annual total compensation of Dr. Kramer, our Chief Executive Officer.
Ratio
For 2020,
•
The median of the annual total compensation of all of our employees, other than Dr. Kramer, was $51,464.
​
•
Dr. Kramer’s annual total compensation was $5,757,874. This is the same amount reported in the Total column of the 2020 Summary Compensation Table.
​
•
Based on this information, the ratio of the annual total compensation of Dr. Kramer to the median of the annual total compensation of all employees is estimated to be 112 to 1.
​
Identification of Median Employee
We selected December 31, 2020 as the date on which to determine our median employee. As of that date, we had approximately 3,708 employees. In addition, as is permitted by the SEC’s executive compensation disclosure rules, we eliminated 147 employees in China (approximately 4.0% of our total employee population) from the data set.
For purposes of identifying the median employee from this data set, we considered the base salary, annual incentive and retirement plan contributions of the employees in the data set for the 12-month period ended December 31, 2020. Next, utilizing the methodology established in consultation with the Committee’s independent consultant, we statistically narrowed down the employee population to a group of employees with the highest probability of containing the median employee using a stratification process based on base salary. As approximately 95% of the statistical sample of employees worked in the U.S. and France, this established the range of employees (318) from which the median would be derived. Then, using three-year gross wage data, we isolated a narrow subset of the median employee population that had stable earning histories and were within a 5% range of the median employee for 2018-2020. Finally, we calculated the 2020 annual total compensation in accordance with Item 402(c)(2)(x) of Regulation S-K for this subset of median employees and, for purposes of this pay ratio disclosure, selected from this subset of employees the median employee who we believe is most representative of the typical employee at the Company.
Compensation of Directors
Every other year, the Compensation Committee reviews non-employee director compensation to evaluate whether non-employee director compensation is consistent with market practices. In connection with the 2019 pay review and after considering input from Willis Towers Watson, the Board increased the stock and cash portions of the annual Board retainer for the January 1, 2020 through December 31, 2021 period from $85,000 to $95,000 and from $60,000 to $70,000, respectively. In 2020, each non-employee director received the following cash and stock compensation for service on our Board and its committees:
•
An annual Board retainer of $95,000 in stock plus $70,000 in cash. Retainers are paid quarterly, with the stock retainer valuation based on the closing price on the trading day immediately preceding the grant date and prorated for one partial quarter of service.
​
•
Additional annual retainer for the Non-Executive Chairman was $75,000 per year, paid quarterly in cash.
​
•
Directors who serve on committees receive an additional annual retainer, paid quarterly in cash as follows:
​
•
Audit Committee: $30,000 for Chair; $15,000 for other members
​
•
Compensation Committee: $20,000 for Chair; $10,000 for other members

The amounts shown in this column are valued based on the aggregate grant date fair value computed in accordance with FASB ASC Topic 718. As of December 31, 2020, the total number of stock awards outstanding per director, in the form of shares or share units, were as follows: Ms. Borg — 5,184; Mr. Bye — 2,729; Mr. Caldabaugh — 41,796; Mr. Keenan — 56,453; Mr. Levi — 8,941; Dr. Ritrievi — 10,843; Mr. Rogers — 34,386; and Mr. Warlick — 50,660.

Mr. Caldabaugh resigned from the Board of Directors, effective at the Company’s 2020 annual meeting of shareholders.
​
U.S. directors may elect to defer all or part of their compensation to the Deferred Compensation Plan No. 2 for Non-Employee Directors, a non-qualified, deferred compensation plan established in 2005 to allow participants to defer receipt of compensation and payment of certain federal and state income taxes. Each participating director has an individual deferral account that is credited with cash or stock units, which include accumulated dividends. Cash credits accrue market-based investment earnings. The stock units do not have any voting rights. Because of regulatory changes, Deferred Compensation Plan No. 2 replaced the Deferred Compensation Plan for Non-Employee Directors in effect from 2000 to 2004, which operated in a similar manner. The earlier plan was frozen as of December 31, 2004 to stop the accrual of additional unvested benefits, other than market-based investment earnings or losses on individual account balances as of that date. The Company provides no guaranty of repayment of the principal amount deferred or of any earnings on the participants’ account balances in either plan. In 2020, the Company amended the Deferred Compensation Plan No. 2 to provide that stock units credited under the plan will be settled in shares of Common Stock rather than cash.

TABLE OF CONTENTS​
CORPORATE GOVERNANCE
Board of Directors and Standing Committees
Board Leadership Structure
The Board is led by the Chairman of the Board. Since 2019, Mr. Rogers has served as Chairman of the Board. As an independent director, Mr. Rogers serves as Non-Executive Chairman.
The Board believes that whether one person should simultaneously occupy the offices of Chairman of the Board and Chief Executive Officer should be determined by the Board in its business judgment, on a periodic basis, including at any time there is a vacancy in either position, after considering relevant factors at the time, such as the specific needs of the business and the best interests of the Company and its stockholders. When the same person holds the Chairman and Chief Executive Officer roles or when the Chairman is not independent, the independent directors elect a Lead Non-Management Director for a two-year term, and after two of such terms, he or she becomes ineligible to stand for re-election to that position for at least one term.
The Non-Executive Chairman acts as liaison between the Chief Executive Officer and the independent directors. The Non-Executive Chairman or non-management directors as a group can retain such independent experts they deem to be necessary or desirable, with the costs borne by the Company. There is also total freedom of communication between any director and the Chief Executive Officer and any other member of management, and such communications are not required to go through the Non-Executive Chairman or the Chief Executive Officer, in the case of director communication with other members of management. The Non-Executive Chairman will be available for consultation and direct communication if requested by any major stockholder of the Company.
Director Independence
An independent director is a person who is free from any relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. Annually, the Board will assess the independence of each non-management director based on the existence or absence of a material relationship with the Company (either directly or as a partner, stockholder or officer of an organization that has a relationship with the Company). In addition to the independence standards of the SEC and the NYSE, the Board has adopted certain categorical standards of independence. The following persons shall not be considered independent:
a. A director who is employed by the Company or any of its affiliates for the current year or any of the past five years.
b. A director who is, or in the past five years has been, affiliated with or employed by a (present or former) auditor of the Company (or of an affiliate).
c. A director who is, or in the past five years has been, part of an interlocking directorate in which an executive officer of the Company serves on the compensation committee of another company that concurrently employs the director.
d. A director who is, or in the past five years has been, a Family Member of an individual who was employed by the Company or any of its affiliates as an executive officer. The term “Family Member” shall mean a person’s spouse, parents, children, siblings, mothers and fathers-in-law, sons and daughters-in-law, brothers and sisters-in-law, and anyone (other than household employees) who shares such person’s home.

TABLE OF CONTENTS
Board Evaluation
The Board and its committees conduct annual self-evaluations, and the Non-Executive Chairman or Lead Independent Director, as applicable, may also engage individual Board members regarding Board or Committee performance. Evaluations of individual directors occur in connection with the evaluation of each director’s nomination for re-election to an additional term and also after completing the first year of Board service for any new director. The Nominating & Governance Committee oversees the Board, committee, and individual evaluation processes.
Board Exercise of Risk Oversight
The Board exercises oversight of enterprise risk at a number of levels and utilizes formal and informal mechanisms to do so.
The Audit Committee plays a material role in oversight of financial, disclosure and liquidity risk issues and oversees the internal control mechanisms used by management in both the financial and non-financial areas. The Audit Committee regularly discusses with management major financial and cyber security risk exposures, compensation risks and other risks, and the steps management has taken to monitor and control such exposures. Virtually every Audit Committee meeting includes items relating to risk review, including ongoing review of financial results, control issues, compliance audit processes and results, debt covenant compliance, hedging activities and liquidity measures. The Audit Committee has regular interaction with the Company’s independent auditors throughout the year, including executive sessions to address internal control and other matters.
The Nominating & Governance Committee regularly assesses the Company’s governance controls. It also undertakes an ongoing review of succession planning, including to assure an appropriate process exists to find appropriately qualified replacement directors as needed for the Board and its committees and to maintain the continuity of management.
The Compensation Committee assesses compensation design and levels from the perspectives of market reasonableness and appropriateness to the objectives of retaining the quantity and level of management expertise and depth required for the successful execution of the Company’s business goals. The Compensation Committee also assesses the risk posed by the Company’s compensation program design and practices and the probability that they might result in adverse impacts on the Company.
The Board as a whole regularly reviews financial performance and risks to that performance, competitive market situations, risks to operations and operating capabilities, regulatory change and strategic planning. These reviews are provided through regularly scheduled financial and operations reviews and regular Committee Chair reports to the Board. More in-depth reviews are provided periodically on selected topics, e.g., litigation and regulatory compliance, customer satisfaction and performance assessments and strategic planning.
The Company maintains an internal audit department and an Enterprise Risk Management (“ERM”) function to oversee the development, implementation and ongoing refinement of a comprehensive ERM program. As part of this program, we undertake an extensive exercise to identify and assess the most significant risks across the enterprise. This annual process includes a robust analysis of both internal and external factors that may impede our ability to execute our strategies, meet business objectives or achieve stakeholder requirements and expectations. We also conduct interviews with senior leaders to identify material risks. This leads us to develop and execute comprehensive actions to manage or mitigate these risks. Furthermore, we continuously monitor these risks and the evolving environment to proactively identify and respond to shifting or emerging risks and strive to provide ongoing assurance that risks are effectively and efficiently managed.
Cyber Security Matters
Oversight of cyber security risk is a joint responsibility of the Board and the Audit Committee. The Audit Committee reviews IT risk as part of the quarterly internal audit and ERM update it receives. The Company’s Chief Information Officer will brief the Board on information security matters at least once annually. The Company maintains a cyber security insurance policy.
49

TABLE OF CONTENTS
In addition to oversight by the Audit Committee and Board, the Company has a Working Council chaired by the Company’s Chief Information Officer and an Executive Council chaired by the Company’s Director of Security and Infrastructure that meet regularly to assess the Company’s response to IT and cyber security priorities.
As part of the Company’s compliance program, the Company provides educational videos and training to employees on an annual basis that include cyber security risk management awareness and sends employees monthly notifications regarding potential cyber security risks. The Company also routinely performs assessments of IT and cyber security risks and maintains controls to mitigate those risks.
Environmental and Social Matters
We believe that building long-term value for our customers, employees and stockholders includes a focus on ensuring the long-term sustainability of our business, good corporate citizenship, and contributing to our communities. Corporate responsibility has long been part of the SWM corporate mission and is one of our core values. Our manufacturing facilities and corporate office have a longstanding tradition of community engagement and reducing our impact on the environment. We maintain our Code for Responsible Procurement and our Sustainable Forestry Policy to further align with our sustainability goals. Our sustainability initiatives are further described on our corporate website at https://www.swmintl.com/expertise/sustainability.
Across SWM, we conduct business in a manner that highly values responsible environmental, social, and ethical practices. Some of our key environmental and social initiatives are highlighted below:
Environmental Initiatives
•
Sustainable Packaging Material: We manufacture Cocoa PaperTM as packaging material. Cocoa PaperTM is made from botanical fibers and is an eco-efficient product. Cocoa PaperTM fibers are 100% carbon neutral, a first in the Engineered Papers (EP) portfolio. Sales of Cocoa PaperTM benefit the Jacundá Forestry REDD+ Project in Brazil through the purchase of carbon credits to offset the impact of projected product sales.
​
•
Sustainable Innovation: SWM developed Revonex TM membrane backing paper which improves reverse osmosis filtration efficiency by eliminating bleed-through. In support of the circular economy, SWM has transformed manufacturing byproducts into FlaxBed TM, specialty animal bedding, and BioLoxx TM spill absorbent, to help protect the environment.
​
•
Partnership with Planet Water Foundation: SWM partners with Planet Water Foundation to support global efforts to improve access to clean, safe water. Currently, the partnership is focused on installing AquaTower water systems in two communities without adequate access to safe water ― Jalisco, Mexico and the Siem Reap Province, Cambodia. Each AquaTower system can produce up to 1,000 liters of clean water per hour, addressing the drinking needs of up to 1,800 people with each tower. SWM also funded the installation of two AquaSan sanitation systems, with the AquaTowers, that meet World Health Organization standards, three AquaHome solutions to provide families with solar powered electricity and drinking water at home, and two community-based education workshops focused on water-health and hygiene education.
​
•
Ethical Sourcing: 100% of the wood pulp that SWM uses is sourced from Forest Stewardship Council (FSC) and/or Programme for the Endorsement of Forest Certification (PEFC)-certified suppliers.
​
•
Environmental Certification and Energy Efficiency: All of our Engineered Paper (EP) locations are certified to ISO 14001 for environmental management systems. Our mills in France are certified to the ISO 50001 energy management standard.
​
•
Biodiversity Support: SWM has a history of supporting local biodiversity initiatives, such as the installation of salmon and eel runs in the Isole River near our EP facility in Quimperlé, France, and the planting of native trees and rebuilding of natural habitat near our plant in Santanesia, Brazil.
​
•
Recycling: Our U.S.-based Advanced Minerals and Structures manufacturing sites have incorporated more than 2 million pounds of recycled plastic into new products and across SWM more than
​
50

TABLE OF CONTENTS
1,000 tons of cardboard were recycled. Many other initiatives are in place involving the reuse of waste products and packaging materials.
Community Initiatives
•
Vera Institute of Justice: Since 2019, SWM has been a financial donor of the Vera Institute of Justice. The Vera Institute was co-founded by Louis Schweitzer, the son of the Company’s co-founder, Peter Schweitzer, and was named after Louis’ mother and Peter’s wife, Vera, who served for a time as the president of Schweitzer, Inc., one part of the company known today as Schweitzer-Mauduit International, Inc. The Vera Institute works in partnership with public sector leaders across the nation to secure equal justice, end mass incarceration, and strengthen families and communities.
​
•
Brazil Trainee Program: SWM works in partnership with the Brazilian federal government to train young professionals for the job market. Every year, trainees are given an opportunity to work at SWM or industrial companies as mechanics, electricians, or administrative assistants.
​
•
Community Support: In various ways, our facilities participate in philanthropic activities around the world, including programs to benefit local children and seniors and raising funds for larger organizations.
​
We continue to look for ways to enhance the sustainability of our business and make a positive impact on the communities in which we live and serve. We periodically hold activities at several of our manufacturing locations and our corporate office involving safety, the environment, community engagement, and employee engagement.
Recognitions
We are proud to report that in 2020 we received an A- score for our CDP Climate Change and Water Security responses, a B for our CDP Forest response, as well as our fourth consecutive silver medal for Corporate Social Responsibility (CSR) recognition from EcoVadis, an organization that rates sustainability practices.
Corporate Governance Documents
We have adopted a code of conduct (the “Code of Conduct”) that applies to all of our directors, officers and employees, including our principal executive officer, principal financial officer, principal accounting officer and other persons performing similar functions. The Code of Conduct is posted on the Governance page of the Company’s website at https://www.swmintl.com/about-us/governance/codes-of-conduct/​. To the extent required under applicable SEC and NYSE rules, any waivers of, or changes to, the Code of Conduct will be posted on our website or otherwise publicly disclosed. In addition, copies of the Company’s Corporate Governance Guidelines and the charters for each of the Standing Committees can also be found on the Governance page of the Company’s website at https://www.swmintl.com/about-us/governance/charters-and-guidelines/​. Copies of these documents may also be obtained by directing a written request to the Investor Relations Department at Schweitzer-Mauduit International, Inc., 100 North Point Center East, Suite 600, Alpharetta, Georgia 30022.

TABLE OF CONTENTS
Pre-approval Policies and Procedures
All of the services listed above and performed by the outside auditor were pre-approved in accordance with the pre-approval policy and procedures adopted by the Audit Committee. These procedures describe the permitted audit, audit-related, tax and other services (collectively, the “Disclosure Categories”) that the outside auditor may perform. The procedures require that prior to the beginning of each fiscal year, a description of the services (the “Service List”) in each of the Disclosure Categories expected to be performed by the outside auditor in the following fiscal year be presented to the Audit Committee for pre-approval.
Services provided by the outside auditor during the following year that are included in the Service List are pre-approved by the Audit Committee in accordance with its pre-approval policy and procedures. Any requests for audit, audit-related, tax, and other services not contemplated on the Service List must be submitted to the Audit Committee for specific pre-approval and cannot commence until such approval has been granted. Pre-approval is typically reviewed and granted at regularly scheduled meetings of the Audit Committee; however, the authority to grant specific pre-approval between meetings, if necessary, has been delegated, subject to certain dollar limitations, to the Chair of the Audit Committee. In the event of specific pre-approval granted by the Chair between meetings of the Audit Committee, the Chair is required to update the Audit Committee at its next regularly scheduled meeting on such grant.
In addition, although not required by the rules and regulations of the SEC, the Audit Committee is provided a range of fees associated with each proposed service on the Service List and any services that were not originally included on the Service List. Providing a range of fees for a service incorporates appropriate oversight and control of the outside auditor when time is of the essence. The policy does not contain a de minimis provision that would provide retroactive approval for permissible non-audit services under certain circumstances.
On a periodic basis, the Audit Committee reviews the status of services and fees incurred to-date against the Service List and the forecast of remaining services and fees for the applicable fiscal year.

AUDIT COMMITTEE REPORT
The following report summarizes the Audit Committee’s actions during 2020. This report shall not be deemed to be incorporated by reference by any general statement incorporating this Proxy Statement by reference into any filing under the Exchange Act or the Securities Act of 1933, as amended, except to the extent that the Company specifically incorporates this information by reference, and shall not otherwise be deemed filed under such acts.
In accordance with its written charter, the Audit Committee assists the Board of Directors by overseeing and monitoring:
(1)
the integrity of the Company’s financial statements;
​
(2)
the Company’s compliance with legal and regulatory requirements;
​
(3)
the outside auditor’s qualifications and independence; and
​
(4)
the performance of the Company’s internal control function, its system of internal and disclosure controls, and the outside auditor.
​
The members of the Audit Committee meet the applicable independence and experience requirements of the SEC and the NYSE and the standards for determining a director’s independence adopted by the Board.
The Audit Committee reviewed and discussed the audited financial statements of the Company as of and for the fiscal year ended December 31, 2020 with management and Deloitte & Touche, the Company’s outside auditor. Management is responsible for the preparation of the Company’s financial statements, and the outside auditor is responsible for conducting an audit of such financial statements.
The Audit Committee has received from the outside auditor the written disclosures and the letter required by applicable requirements of the Public Company Accounting Oversight Board (United States) regarding the outside auditor’s communications with the Audit Committee concerning independence, has discussed the independence of the outside auditor with the outside auditor and has satisfied itself as to the outside auditor’s independence.
The Committee reviewed with the outside auditor its audit plans, audit scope and identification of audit risks. The Audit Committee also discussed with management and the outside auditor the quality and adequacy of the Company’s internal control function and its system of internal and disclosure controls.
The Audit Committee discussed and reviewed with the outside auditor all communications required by SEC regulations and by the standards of the Public Company Accounting Oversight Board (United States), and, with and without management present, discussed and reviewed the results of the outside auditor’s examination of the financial statements.
The Audit Committee discussed, reviewed and monitored the Company’s plans and activities related to compliance with Section 404 of the Sarbanes-Oxley Act of 2002 on a regular basis.
Based on the above-mentioned reviews and discussions with management and the outside auditor, the Audit Committee recommended to the Board that the Company’s audited financial statements be included in its Annual Report on Form 10-K for the fiscal year ended December 31, 2020 for filing with the SEC.
The Audit Committee also recommended the reappointment of Deloitte & Touche to serve as the Company’s outside auditor for fiscal year 2021, and the Board concurred with such recommendation.

PROPOSAL THREE
NON-BINDING ADVISORY VOTE TO APPROVE EXECUTIVE COMPENSATION
As required by Section 14A of the Exchange Act pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, or the Dodd-Frank Act, the Board is providing our stockholders with an advisory vote on Executive Compensation. This advisory vote, commonly known as a “say on pay” vote, is a non-binding vote on executive compensation paid to our Named Executive Officers as disclosed pursuant to Regulation S-K, including in the “Compensation Discussion & Analysis,” the accompanying compensation tables and the corresponding narrative discussion and footnotes set forth on pages 14 to 43. The Company intends to submit this “say on pay” vote to its stockholders annually, consistent with the results of the advisory vote on frequency approved by the stockholders at the 2017 Annual Meeting of Stockholders.
As described in detail in the Compensation Discussion & Analysis, the Compensation Committee of the Board believes that the Company’s executive compensation program should reward actions and behaviors that build a foundation for the long-term performance of the Company, while also rewarding the achievement of short-term performance goals informed by the Company’s strategy. To align the Company’s executive compensation program with the Committee’s compensation philosophy, the Compensation Committee has adopted the following objectives:
•
Pay-for-performance
​
•
Align performance goals and executive compensation with stockholder interests
​
•
Total target compensation set within a range of market median value for like skills and responsibilities to attract, retain and motivate executive officers
​
We are committed to having strong governance standards with respect to our executive compensation program, policies and practices. Consistent with this focus, we maintain the following policies and practices that we believe demonstrate our commitment to executive compensation best practices.

​ | ​ | What We Do: | ​ | ​
​ | ​ | ✓ | ​ | ​ | ​ | Pay-for-performance. | ​ | ​
​ | ​ | ✓ | ​ | ​ | ​ | Linkage between quantitative performance measures and operating objectives. | ​ | ​
​ | ​ | ✓ | ​ | ​ | ​ | “Double trigger” in the event of a change-in-control other than with respect to a grandfathered compensation arrangement. | ​ | ​
​ | ​ | ✓ | ​ | ​ | ​ | Independent compensation consultant. | ​ | ​
​ | ​ | ✓ | ​ | ​ | ​ | Stock ownership guidelines. | ​ | ​
​ | ​ | ✓ | ​ | ​ | ​ | Clawback policy. | ​ | ​
​ | ​ | ✓ | ​ | ​ | ​ | Annual risk assessment. | ​ | ​
​ | ​ | ✓ | ​ | ​ | ​ | Annual peer group review. | ​ | ​

​ | ​ | What We Don’t Do: | ​ | ​
​ | ​ | × | ​ | ​ | ​ | No change-in-control tax gross-ups. | ​ | ​
​ | ​ | × | ​ | ​ | ​ | The Company does not re-price stock options or buy-back equity grants. | ​ | ​
​ | ​ | × | ​ | ​ | ​ | The Company does not allow directors and key executives (including all Named Executive Officers) to hedge or pledge their Company securities. | ​ | ​

We believe that our executive compensation practices, in combination with a competitive market review, contribute to an executive compensation program that is competitive yet strongly aligned with stockholder interests.
Accordingly, the Board recommends that our stockholders vote for the “say on pay” vote as set forth in the following resolution:
RESOLVED, that our stockholders approve, on an advisory basis, the compensation paid to our Named Executive Officers, as disclosed pursuant to Item 402 of Regulation S-K, including in the
56

TABLE OF CONTENTS
“Compensation Discussion & Analysis,” the accompanying compensation tables and the corresponding narrative discussion and footnotes.
Stockholders are not ultimately voting to approve or disapprove the Board’s recommendation. As this is an advisory vote, the outcome of the vote is not binding on SWM with respect to future executive compensation decisions, including those relating to its Named Executive Officers, or otherwise. The Compensation Committee and Board expect to take into account the outcome of the vote when considering future executive compensation decisions.
Board Recommendation
The Board of Directors unanimously recommends a vote FOR the approval of the advisory resolution relating to the compensation of our Named Executive Officers as disclosed in this Proxy Statement.
