PROXY STATEMENT

On April 1, 2016, we became an independent public company as a result of the separation by Armstrong World Industries, Inc. (“AWI”) of its Resilient Flooring and Wood Flooring segments from its Building Products segment (the “Separation”). On December 31, 2018, we sold our Wood Flooring business.

We prepared this Proxy Statement under the direction of our Board of Directors (the “Board”) to solicit your proxy for use at our 20192020 Annual Meeting of Stockholders to be held via the Internet on Tuesday,Friday, June 4, 20195, 2020 at 9:00 a.m. Eastern time (the “Annual Meeting”). When we refer to “we,” “our,” “us,” “Armstrong Flooring,” “AFI” and the “Company” in this Proxy Statement, we are referring to Armstrong Flooring, Inc. This Proxy Statement (“Proxy Statement”) and the related materials are first being distributed to stockholders on or about April 24, 2019.2020.

QUESTIONS & ANSWERS

Why am I being asked to review these materials?

In order to solicit your proxy, we must furnish you with this Proxy Statement, which contains information about the proposals to be voted upon at the Annual Meeting.

As of the Record Date, 25,932,26921,555,833 Common Shares were issued and outstanding and entitled to vote at the Annual Meeting, which number excludes 2,361,4526,801,825 Common Shares held in treasury.

If your shares are registered directly in your own name with our transfer agent, AST Financial (“AST”), you are considered a “stockholder of record” with respect to those shares, and the Notice has been sent directly to you. If you hold your shares through a broker, bank or other nominee, you are considered a “beneficial owner” of those shares, holding such shares in “street name.” If you are a beneficial owner of shares, you will receive instructions from your broker or other nominee describing how to instruct your broker or nominee to vote your shares. To vote online at the Annual Meeting, beneficial owners will need to contact the broker, trustee or nominee that holds their shares to obtain a “legal proxy” that will permit them to vote their shares via the Internet at the meeting.

What is the deadline for voting if I do not plan to attend the Annual Meeting?

You may vote via the Internet or by telephone until 11:59 p.m., Eastern Time, on June 3, 2019,4, 2020, or Broadridge Investor Communications Solutions, Inc. must receive your paper proxy card by mail on or before June 3, 2019.4, 2020.

Can I change my vote after I have delivered my proxy?

A subsequent vote will change your prior vote. The last vote received prior to the Annual Meeting will be the one counted. If you are a stockholder of record, you may also change your vote by voting online during the Annual Meeting. Beneficial owners wishing to change their votes after returning voting instructions to their broker or other nominee must contact the broker or nominee directly.

Can I revoke a proxy?

Yes. A stockholder of record may revoke a properly executed proxy at any time before its exercise by submitting a letter addressed to, and received by, our Corporate Secretary, by delivering later dated proxy instructions or by voting online during the meeting. Beneficial owners cannot revoke their proxies at the Annual Meeting because the registered stockholders (the broker, bank or other nominees) will not be present. Beneficial owners who wish to vote online during the Annual Meeting must obtain a legal proxy from their broker, bank or other nominee.

Who will vote my shares at the Annual Meeting and how will they vote my shares if I provide voting instructions and/or grant my proxy?

Larry S. McWilliams, Chair of the Board, and James C. Melville, Chair of the Board’s Nominating and Governance Committee (the “Governance Committee”), were designated by the Board to vote all proxies, or record an abstention, or withholding, in accordance with the directions on the proxy. If no contrary direction is given, the shares will be voted as recommended by the Board.

Who will count the votes and how much does it cost the Company?

We have engaged Broadridge Investor Communications Solutions, Inc. to tabulate the proxy votes for a fee of approximately $18,000 plus reasonable expenses.

What is a quorum? Why is a quorum required?

It is important that your proxy be returned because a quorum is required for our stockholders to conduct business at the Annual Meeting. The presence at the meeting via the Internet or representation by proxy of the holders of

Common Shares having a majority of the voting power represented by all issued and outstanding Common Shares entitled to vote on the Record Date will constitute a quorum, allowing us to conduct the business of the meeting. Proxies received but marked as abstentions, if any, will be included in the calculation of the number of shares considered to be present at the meeting for quorum purposes. Because this Proxy Statement includes a “routine” management proposal, shares represented by “brokernon-votes” will be counted in determining whether there is a quorum present. If there is not a quorum present at the Annual Meeting, we will be forced to reconvene the Annual Meeting at a later date.

What is the effect of an abstention?

The shares of a stockholder who abstains from voting on a matter will be counted for purposes of determining whether a quorum is present at the Annual Meeting, so long as the stockholder is present via the Internet or represented by proxy. With regard to the election of directors, votes may be cast “for,” “against,” or “abstain,” and votes to abstain will have no effect. Abstentions may be specified on all other proposals. An abstention from voting on a matter by a stockholder present via the Internet or represented by proxy at the Annual Meeting has the same legal effect as a vote “against” approval of the compensation of our named executive officers (“NEOs”) and ratification of the selectionappointment of KPMG LLP as our independent registered public accounting firm for 2019.2020.

2

How will votes be counted on shares held through brokers?

If you are a beneficial owner and do not provide your broker with voting instructions, your shares may constitute “brokernon-votes.” Generally, brokernon-votes occur on a matter when a broker is not permitted to vote on that matter without instructions from the beneficial owner and instructions are not given. Brokers are not entitled to vote on the election of directors or the advisory proposal to approve the compensation of our NEOs unless the brokers receive voting instructions from the beneficial owner. The shares of a stockholder whose shares are not voted because of a brokernon-vote on a particular matter will be counted for purposes of determining whether a quorum is present at the Annual Meeting so long as the stockholder is represented by proxy. In tabulating the voting result for any particular proposal, shares that constitute brokernon-votes are not considered present and entitled to vote on that proposal. Thus, brokernon-votes will not affect the outcome of any matter being voted on at the Annual Meeting, assuming that a quorum is obtained. Brokers will be permitted to vote without voting instructions on the ratification of the selectionappointment of KPMG LLP as our independent registered public accounting firm for 2019,2020, assuming that a quorum is obtained.

How many votes are needed to approve each of the proposals?

Each director nominee will be elected by a plurality of the votes cast at the Annual Meeting. A plurality means that the nominees with the largest number of votes are elected as directors up to the maximum number of directors to be chosen at the Annual Meeting.

Approval, on an advisory basis, of the compensation of our NEOs requires the affirmative vote of a majority of the Common Shares present via the Internet during the meeting or represented by proxy and entitled to vote at the Annual Meeting.

The ratification of the appointment of KPMG LLP as our independent registered public accounting firm for 20192020 requires the affirmative vote of a majority of the Common Shares present via the Internet during the meeting or represented by proxy and entitled to vote at the Annual Meeting.

What does it mean if I receive more than one proxy card or voting instructions?

This means that you have multiple accounts in which you own our Common Shares. Please vote all proxy cards/voting instructions from us to ensure that all of your Common Shares are voted. However, you may want to contact your broker, your bank or our transfer agent to consolidate as many accounts as possible under a single

name and address. Our transfer agent is AST. All communications concerning Common Shares you hold in your name, including address changes, name changes, requests to transfer and similar issues, can be handled by contacting AST, 6201 15^th Avenue Brooklyn, NY 11219; or by email toinfo@astfinancial.com; or by phone(1-800-937-5449).

List of Stockholders

A list of our stockholders will be available for inspection for the 10 days prior to the Annual Meeting. In light of restrictions related toCOVID-19, if you want to inspect the stockholder list, call our Investor Relations department at (717) 672-9300 to schedule an appointment. In addition, the list of stockholders will also be available during the Annual Meeting through the meeting website for those stockholders who choose to attend.

What should we do if multiple stockholders reside in our household, and we wish to change the number of copies of proxy materials that we receive?

Some banks, brokers, broker-dealers and other similar organizations acting as nominee record holders may be participating in the practice of “householding” proxy statements and annual reports. This means that only one copy of this Proxy Statement and the annual report may have been sent to multiple stockholders in your household. If you would prefer to receive separate copies of a Proxy Statement or annual report for other stockholders in your household, either now or in the future, please contact your bank, broker, broker-dealer or other similar organization serving as your nominee. Upon written or oral request to the attention of Investor Relations, 2500 Columbia Avenue, P.O. Box 3025, Lancaster, Pennsylvania 17603, via email atIR@armstrongflooring.com, or via telephone to the Investor Relations department at717-672-9300, we will promptly provide separate copies of the annual report and/or this Proxy Statement. Stockholders sharing an address who are receiving multiple copies of the Proxy Statement or annual report and who wish to receive a single copy of such materials in the future will need to contact their bank, broker, broker-dealer or other similar organization serving as their nominee to request that only a single copy of each document be mailed to all stockholders at the shared address in the future.

Where can I find voting results of the Annual Meeting?

We will announce preliminary general voting results at the meeting and publish final detailed voting results on a Current Report on Form8-K that we will file with the U.SU.S. Securities and Exchange Commission (“SEC”) within four (4) business days after the Annual Meeting.

PROPOSAL 1 – ELECTION OF DIRECTORS

Our Board currently consists of nine (9) members, eight (8) of whom were appointed in connection with the Separation when the Company was a wholly-owned subsidiary of AWI. Richard E. Wenz was also appointed in connection with the Separation and passed away on June 29, 2016. Michael W. Malone was appointed to the Board effective October 1, 2016.

Our Amended and Restated Certificate of Incorporation (“Certificate”) and Amended and Restated Bylaws (“Bylaws”) provide that our Board was to be initially divided into three (3) classes, each comprised of three (3) directors. Upon the expiration of the initial term of each class of directors, the directors of such class would thereafter stand for election annually, such that, beginning with this Annual Meeting, our Board will no longer be divided into classes and each director will stand for election annually.

James J. O’Connormembers. Jacob H. Welch will not stand for reelection at the Annual Meeting. The Board and the Company are grateful for Mr. Welch’s contributions, astute guidance and dedicated service during his tenure as a Board member, which commenced at the Separation. Effective as of Mr. O’Connor’sWelch’s resignation from the Board at the Annual Meeting, the size of the Board will be decreased from nine (9)eight (8) to eight (8)seven (7) members.

Based on the recommendation of the Governance Committee, which is composed solely of ‘independent directors’ as defined in the New York Stock Exchange (“NYSE”) Listing Standards, the Board has nominated the following directors for election at the Annual Meeting:

Each nominee is a current member of the Board, and with the exception of Mr. Maier,Vermette, each is an independent member of the Board. Based on this recommendation and each nominee’s prior service to the Board, credentials and experience, the Board has determined that each such nominee can make a significant contribution to the Board and should continue to serve as a director. If elected, these directors will hold office until the 20202021 annual meeting of stockholders and until their successors are elected and qualified.

You may not vote for a greater number of persons than the nominees named in this Proxy Statement.

Each nominee has agreed to be named in this Proxy Statement and to serve if elected. We have no reason to believe that any of the nominees would be unable to serve if elected, but if any nominee is unavailable for election, the proxy holders may vote for another nominee proposed by the Board, in which case your shares will be voted for such other nominee.

The pages that follow include biographical information about each of our nominees, including service as a director, experience, public company directorships held currently or at any time during the last five (5) years, and the qualifications and skills that factored into the Board’s determination that the director should serve on the Board.

EACH OF THE FOREGOING DIRECTOR NOMINEES

CORPORATE GOVERNANCE

CORPORATE GOVERNANCE DOCUMENTS

Our Corporate Governance Guidelines address the responsibilities, duties, service and qualifications of our Board, the determination of a director’s independence and any conflicts of interest, Board access to management and independent advisors, director compensation and stock ownership requirements, Board committees and other matters relating to corporate governance. Our Corporate Governance Guidelines are available on our website under “Investor Relations” and then “Corporate Governance” http://www.armstrongflooring.com/corporate/governance.html. Also available at the same location on our website are: the charters of the Audit Committee, the Management Development and Compensation Committee (the “Compensation Committee”), the Governance Committee, and the Finance Committee of the Board; the Armstrong Flooring Code of Business Conduct, the Armstrong Flooring Code of Ethics for Financial Professionals, the Armstrong Flooring, Inc. Conflicts of Interest and Related Party Transactions Policy; and the Armstrong Flooring Recoupment Policy. Our website is not part of this Proxy Statement and references to our website address in this Proxy Statement are intended to be inactive textual references only.

BOARD LEADERSHIP STRUCTURE

Our Bylaws and Corporate Governance Guidelines provide the Board with the flexibility to determine what leadership structure works best for us, including whether the same individual should serve as both our Chair and our CEO. Larry S. McWilliams serves as the Chair of our Board, while Donald R. MaierMichel S. Vermette serves as our President and CEO, and as a director. The separation of these positions allows Mr. MaierVermette to focus primarily on execution of our business strategy and operations while Mr. McWilliams oversees the Board’s functions. The Board will continue to evaluate its leadership and governance structure within the context of the specific needs of the business, current Board composition, and the best interests of our stockholders.

Responsibilities of the Chair include ensuring and overseeing the:

The Chair is also responsible for providing effective leadership for our independent directors to facilitate the independent oversight required by our Bylaws and Corporate Governance Guidelines, including by ensuring that:

committee periodically meets with designated risk mitigation owners and assesses control measures. In addition, the steering committee regularly reevaluates the appropriateness of risk assessments and priorities. This process includes identifying risks that could prevent achievement of business goals or plans. The internal audit group uses the resulting information as a basis for developing its audit plan.

Each Board committee, consistent with its charter, assists the Board in overseeing the review of certain risks that are particularly within its purview, including as described in “BOARD MEETINGS AND COMMITTEES” below.

BOARD’S ROLE IN SUCCESSION PLANNING

The Board is actively engaged and involved in talent management. The full Board reviews our “Organization Vitality” in support of our business strategy at least annually. More broadly, the Board, through the Compensation Committee, is regularly updated on key talent indicators for the overall workforce, including diversity, recruiting and development programs. This includes a detailed discussion of the Company’s global leadership bench and succession plans with a focus on key positions at the senior officer level, including CEO. During 2018,2019, the Board and the Compensation Committee met in furtherance of these initiatives. In addition, the committees of the Board regularly discuss the talent pipeline for specific critical roles. High potential leaders are given exposure and visibility to Board members through formal presentations and informal events.

9After the departure of Mr. Maier, the Board conducted an extensive evaluation and search process to hire a new CEO. On September 10, 2019, the Company announced the hiring of Mr. Vermette. In hiring Mr. Vermette, the Board considered, among other factors, his domestic and international industry experience, business, operational, financial and strategic expertise, leadership, and track record of improving business performance by implementing product development, manufacturing and operational excellence.

BOARD EVALUATIONEVALUATION

Through the stewardship of the Governance Committee and its Chair and with the assistance of an external, independent third party advisor, the Board engages in a robust self-evaluation process. The process includes an extensive review of matters affecting the Board and each committee, including meeting cadence, sufficiency of materials and presentations from management and candid assessments of a director’s input during and in between meetings. The results of this process are presented by the Governance Committee Chair in a report to the Board during executive session, typically during the first regular meeting of the fiscal year. The Board’s most recent self-evaluation took place during the first quarter of 2019.2020.

BOARD MEETINGS AND COMMITTEES

There are four (4) standing committees of the Board: the Audit Committee, the Compensation Committee, the Governance Committee, and the Finance Committee, as applicable, each described below.

Each standing committee has a charter and consists solely of ‘independent’ or ‘outside’ directors who meet applicable independence standards required by the NYSE, the SEC, and the Internal Revenue Service, and under our Certificate and Bylaws. Each committee reports to the Board regularly and evaluates the effectiveness of its performance annually. The membership of each committee is determined by the Board based on the recommendation of the Governance Committee. The Company’s Corporate Governance Guidelines provide that (i) directors who are currently fully employed should not serve on more than two (2) other corporate boards and (ii) other directors should not serve on more than four (4) other corporate boards.

Our Board met eight (8)nine (9) times during 2018, two (2)2019, three (3) of which were special meetings. All directors who served on the Board during 20182019 participated in at least 75% of the meetings of the Board.Board and committees on which he or she served. Board members are expected to attend annual meetings, which can be done virtually, via the Internet, because our annual meetings may be held virtually.

Audit Committee

The responsibilities of the Audit Committee are more fully described in its charter. Among other responsibilities delegated by the Board, the Audit Committee:

backgrounds, and differences in professional experiences and expertise represented on the Board evidences diversity in many respects. The Board believes that this diversity, coupled with the personal and professional ethics, integrity and values of all of the directors, results in a board that can guide us with good business judgment.

12

The Governance Committee expects each of our directors to have proven leadership, sound judgment, integrity and a commitment to our success. In evaluating director candidates and considering incumbent directors for nomination to the Board, the Governance Committee considers a variety of factors. These include each nominee’s independence, financial literacy, personal and professional accomplishments, and experience in light of the needs of the Company. For incumbent directors, the factors also include past performance on the Board and contributions to their respective committees.

The Governance Committee will consider director candidates nominated by stockholders. When evaluating the candidacy of nominees proposed by stockholders, the Governance Committee may request additional information as it may consider reasonable to determine the proposed nominee’s qualifications to serve as a member of the Board.

The procedures for recommending candidates are posted atwww.armstrongflooring.com/corporate/nominating-governance-committee.html. Stockholders who wish to suggest individuals for service on the Board are requested to review our Bylaws and supply the information required therein in a written request to the Corporate Secretary at the Company’s corporate offices at 2500 Columbia Avenue, P.O. Box 3025, Lancaster, Pennsylvania 17603.

The Chair of the Annual Meeting or any other annual or special meeting of stockholders may refuse to acknowledge the nomination of any person not made in compliance with the foregoing procedures. A stockholder’s compliance with these procedures will not require us to include information regarding a proposed nominee in our proxy solicitation materials.

COMPENSATION OF DIRECTORS

In establishing our nonemployee director compensation program, including the overall value of compensation and the mix of cash and equity, the Board analyzes competitive market data and any underlying director compensation trends generally, and compares our program to those of similarly sized companies in comparable industries. Our nonemployee directors are compensated through a combination of annual retainers and equity grants in the form of stock units. The Board believes that this level of compensation supports the Company’s ability to attract nonemployee directors with suitable backgrounds and experiences. A director who is an officer or employee of the Company or its subsidiaries is not compensated for service on the Board or on any committee of the Board. Directors are reimbursed for business expenses related to attendance at Board and committee meetings and for attendance at qualified third-party director education programs.

The Governance Committee, which is composed solely of independent directors, has the primary responsibility to review and consider any revisions to the nonemployee director compensation program. The Governance Committee reviewed the nonemployee director compensation program in 2018 and determined that no revisions were warranted.2019. In December 2019, upon recommendation of the Governance Committee, the Board, with the Chair of the Governance Committee abstaining from the vote, increased the annual retainer for service as Chair of the Governance Committee to $20,000 effective January 1, 2020, which is consistent with fees paid for service as Chair of the other committees of the Board.

The following table describes the elements of the nonemployee director compensation program:

DIRECTORS STOCK UNIT PLAN

Prior to the Separation, the board of directors of AWI approved the 2016 Directors Stock Unit Plan as AFI’s sole stockholder. The 2016 Directors Stock Unit Plan is designed to promote the growth and profitability of AFI by increasing the mutuality of interests between AFI’snon-employee directors and the AFI stockholders. The planPlan provides for the issuance to nonemployee directors of “units,” or rights to receive Common Shares (“Director RSUs”), which rights may be made conditional upon continued service or the occurrence or nonoccurrence of specified events. Except as otherwise determined by the planPlan administrator and unless deferred by the director, the units awarded under the planPlan will generally vest and settle, contingent on continued service as a director, on the earlier to occur of the next annual stockholders meeting, the date of the director’s death or disability, or the date of a “change in control” (as such term is defined in the plan)Plan) of AFI.

The 2016 Directors Stock Unit Plan is generally administered by the Governance Committee, which has the authority to (i) make discretionary grants of units to eligible directors; (ii) prescribe terms, conditions, limitations and restrictions applicable to any grant; and (iii) interpret the plan,Plan, adopt, amend and rescind rules relating to the 2016 Directors Stock Unit Plan and make all other determinations necessary or advisable with respect to the plan.Plan.

Upon the occurrence of certain corporate events that affect the Company’s common stock, including but not limited to extraordinary cash dividends, stock splits, reorganizations or other relevant changes in capitalization, the administrator will make appropriate adjustments with respect to the number of shares available for grants under the 2016 Directors Stock Unit Plan, the number of units covered by existing grants and the maximum number of shares that may be granted to any participant.

The maximum grant date value of the Common Shares subject to grants of Director RSUs made to a participant during any one calendar year, taken together with any cash fees earned by such participant during the calendar year, will not exceed $600,000 in total value. For purposes of this limit, the value of grants will be calculated based on the grant date fair value for financial reporting purposes.

STOCK OWNERSHIP GUIDELINES

The Governance Committee, following a review of current trends for stock ownership requirements of nonemployee directors, established stock ownership guidelines for all nonemployee directors that require each nonemployee director to achieve and hold Common Shares representing an amount equal to five (5) times the director’s annual cash retainer within five (5) years. None of the nonemployee directors has attained his or her stock ownership target as of the date of this Proxy Statement.

Our 20182019 Business Performance

In December 2018, the Company completed the previously announced sale of its wood flooring business.  2018 performance goals include the wood flooring business since it was not sold or classified as a discontinued operation until the end of the fourth quarter. Figures below include total Company results.

Our 20182019 adjusted EBITDA performance of $71$24 million was higher than 2017 performance of $65 million but slightlysignificantly below our $75$66 million target, resulting in a 2018no 2019 AIP payout below target.to our NEOs. Adjusted EBITDA (Earnings before interest, taxes, depreciation, and amortization) is anon-GAAP measure.

The underperformance was primarily due to continued strong inflationary pressures combinedlower net sales (primarily driven by unfavorable volumes, reflecting relative changes in distributor inventory levels compared to the prior year due to significant customer purchases in 2018 ahead of U.S. tariff increases), and increased input cost inflation pressure, partially offset by improved productivity.

The Company has implemented a new operating model to more effectively accomplish its three objectives under its multi-year roadmap. The operating model is entirely centered on strengthening the Company’s connection with volume declines in portions of our legacy portfolio.end customers and repositioning its culture for excellence by:

We believe that these changes will enhance our competitive position and position us to achieve both our medium and long-term goals.

Our 20182019 Executive Compensation Objectives and Actions

The Committee reviews and makes decisions about senior executive compensation, including the amount of base salary, AIP awards and LTIPLTI awards made to our NEOs. The Committee takes into account our financial and business results, individual performance and competitive data and balances short-term goal achievement with long-term shareholder value. In light of these considerations, the Committee made the following executive compensation decisions in fiscal year 2018:2019:

OUR EXECUTIVE COMPENSATION PROGRAM PHILOSOPHY AND OBJECTIVES

Our long-term success and growth depend on attracting and retaining highly capable global business leaders with the experience and skills to deliver our strategy in a volatile and changing market environment. Thus, our executive compensation programs are designed to attract, motivate and retain those high-quality leaders. In developing and maintaining our executive compensation program, the Committee focuses on the following key objectives:

23

Our 20182019 Compensation Practices and Policies

We believe our executive pay is reasonable and provides appropriate incentives to our NEOs to achieve our financial and strategic goals without encouraging them to take excessive risks in their business decisions. We regularly evaluate the major risks to our business, including how risks taken by management could affect the value of executive compensation. To this end, we note the following regarding our compensation practices:

Changes to our 2020 Compensation Practices and Policies

Keeping our compensation philosophy in mind, effective for fiscal year 2020, there have been some enhancements made to the short and long-term incentive plans. The enhancements are intended to further align the Company’s compensation practices with its new operating model centered on strengthening the Company’s connection with end customers and repositioning its culture for excellence. The NEO AIP remains based 100% on financial measurements but the plan has shifted from an EBITDA metric to a 50%/50% weighting of Net Sales and Gross Profit measures. The threshold/target/maximum payout percentages remain unchanged (50%/100%/200%). The long-term incentive plan awards have shifted from 75% PSU/25% RSU to 70% PSU/30% time-based cash. Previously the RSU portion was a graded award that vestedone-third for each of three years and the PSU portion was a three-year cliff award. The PSU portion maintains a three-year cliff vesting schedule, while the new time-based cash design uses atwo-year cliff vesting schedule. The value of the time-based cash award is fixed, while the upside potential under the revised PSU design has been lowered from 200% of target to 125% of target.

How We Make Compensation Decisions

The Committee is responsible for executive compensation program design and the decision-making process relative to NEOs specifically, and broadly, as these programs apply to other senior leaders and participating employees. The Committee solicits input from the independent members of the Board, the CEO, other members of management, and its independent compensation consultant to assist with its responsibilities. The following summarizes the roles of each of the key participants in the executive compensation decision-making process.

Roles of Key Participants

Setting Executive Compensation

We consider market pay practices as a starting reference point when setting executive compensation. The Committee assesses whether our level of executive pay is appropriate when compared to industry and market standards. In general, we target NEO pay to be at or near the 50^th percentile of the competitive market, but we may deviate from this target due to an individual’s performance or tenure in his or her current position, internal equity with peers situated at similar levels, and to attract and retain the required level of global business knowledge and leadership needed to achieve our strategic objectives.

The Committee'sCommittee’s independent compensation consultant assists the Committee in developing the relevant competitive market using published survey data and a peer group of companies to serve as the basis for comparing the pay of our named senior executivesNEOs to the market. Annually, we conduct a detailed market review of executive pay to evaluate each element of pay against the market. Overall, our reported NEOs are generally paid 11% percentat or below our relevant competitive market for base salary and 18% percent below our relevant competitive market.target total direct compensation.

Peer Group

Our peer group is composed of companies with business models and operations comparable to our own and companies that we believe have a similar financial and operational profile. Metrics used to select our peer group include: revenue; market capitalization; business model comparability; global presence; and competition for executive talent. We believe that our peer group reflects the type and complexity of business risks managed by our NEOs and that we compete with many of the companies in our peer group for executive talent.

In fiscal year 2018,2019, the Committee, in consultation with its independent compensation consultant, evaluated the continuing appropriateness of our peer group. Following its review, the Committee approved twoseveral changes. Ply GemFour companies were removed that had significantly larger revenue than the Company (Blue Linx Holdings, was removed asInc., GMS Inc., NCI Building Systems, Inc., and Patrick Industries Inc.). Three companies were added that have revenues more closely in line with the company is no longer publicly traded and BlueLinx Holdings, Inc. was added back to the peer group for 2019 due to its similar industry,Company’s revenue and that have similar market capitalization.capitalization (CSW Industrials, Inc., PH Glatfelter Company, Huttig Building Products, Inc.) Our 20182019 peer group, as determined by the Committee, was as follows:

In fiscal year 2018,2019, the Committee reviewed peer group proxy statement data in evaluating our NEOs’ pay and published compensation survey data in evaluating our other senior executives'executives’ pay. When assessing pay levels, the Committee also reviews the relative positioning of our senior executives with each other. In 2018,2019, the Committee'sCommittee’s consultant advised the Committee that our overall competitive posture for executive pay remained aligned with our pay for performance compensation philosophy.

26

Target Percentile Compensation Opportunity

We target total direct compensation opportunity at or near the 50th percentile relative to our peer group. We believe that targeting pay opportunities at the median of our peer group enables us to retain talented and experienced senior executives and is consistent with market-leading practices.
