PROXY STATEMENT

This proxy statement was prepared under the direction of our Board of Directors (“Board”) to solicit your proxy for use at the annual meeting. When we refer to “we,” “our,” “us,” “Armstrong” and the “Company” in this proxy statement, we are referring to Armstrong World Industries, Inc. This proxy statement and the related materials are first being distributed to shareholders on or about April 23, 2014.

ITEM 1 – ELECTION OF DIRECTORS

On the recommendation of the Nominating and Governance Committee (“Governance Committee”), our Board has nominated the 11 directors listed below for election at the Annual Meeting. The nominees include 10 independent directors, as determined by the Board in accordance with the NYSE listing standards and our Corporate Governance Principles. The eleventh nominee is our President and Chief Executive Officer (“CEO”), Matthew J. Espe. Each nominee’s term would, if elected, run from the date of his election until our next annual shareholders’ meeting, or until his successor, if any, is elected or appointed. We have no reason to believe that any of the nominees will be unwilling or unable to serve if elected.

On March 18, 2014, Kevin R. Burns, a director since 2009, informed us of his intention to not stand for reelection as a director when his term expires at the Annual Meeting. On April 11, 2014, the Board adopted a resolution to fix the number of directors at eleven effective at the Annual Meeting when Mr. Burns’ term expires.

The Governance Committee performs an assessment of the qualifications and experience needed to properly oversee the interests of the Company. In doing so, the Governance Committee believes that aligning director qualifications and skill sets with our business and strategy is essential to forming a Board that adds value for shareholders. While the Board does not have a formal diversity

policy with respect to director nominations, it believes that a Board composed of individuals with diverse attributes and backgrounds enhances the quality of the Board’s deliberations and decisions. The Board has an expansive view of diversity, going beyond the traditional concepts of race, gender and national origin. The Board believes that the diversity of viewpoints, educational 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 the Company with good business judgment.

The Governance Committee expects each of the Company’s directors to have proven leadership, sound judgment, integrity and a commitment to the success of the Company. 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 Board is also particularly interested in maintaining a mix of skills and qualifications that include the following:

Public Company CEO or COO within 5 years

Senior Executive Leadership

Manufacturing & Distribution Operations

Financial Literacy

Significant International Experience

Finance and Capital Markets Transactions

Technology

M&A

Risk Management

Corporate Governance/Law

CORPORATE GOVERNANCE PRINCIPLES AND OTHER CORPORATE GOVERNANCE DOCUMENTS

Our Corporate Governance Principles include guidelines regarding the responsibilities, duties, service and qualifications of our Board, the determination of a director’s independence and any conflict of interests, 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 Principles are available on our website under “Company Information” and then “Corporate Governance” http://www.armstrong.com/corporate/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 (“Compensation Committee”), and Governance Committee of the Board, the Armstrong Code of Business Conduct and the Armstrong Code of Ethics for Financial Professionals. 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.

DIRECTOR INDEPENDENCE

It is the policy of the Company that the Board consist of a majority of directors who are not employees and are independent under all applicable legal and regulatory requirements, including the independence requirements of the New York Stock Exchange (“NYSE”). For purposes of evaluating the independence of directors, in accordance with our Corporate Governance Principles, the Board will consider all relevant facts and circumstances in making an independence determination, and not merely from the standpoint of the director, but also from that of persons or organizations with which the director has an affiliation. Consistent with our Corporate Governance Principles, to be considered “independent,” the Governance Committee has established qualifications to assist in the determination, which either meet or exceed the independence requirements of the NYSE.

The Board has determined that all of our directors, with the exception of Mr. Espe, our President and CEO, are independent under NYSE listing

standards and our Corporate Governance Principles. In addition, the Board has further determined that each of the members of the Audit Committee, the Compensation Committee and the Governance Committee are independent within the meaning of the NYSE listing standards, any applicable minimum standards required by the Securities and Exchange Act of 1934 (the “Exchange Act”) and enhanced standards required for membership on such committees by our Bylaws, namely that directors serving on such committees meet the independence criteria under both NYSE rules and Rule 10A-3(b)(1) under the Exchange Act.

BOARD’S ROLE IN RISK MANAGEMENT OVERSIGHT

The Board oversees the Company’s risk profile and management’s processes for assessing and managing risk, both as a full Board and through its committees, which meet regularly and report to the full Board. Management is charged with managing risk through robust internal policies and controls.

The Company has maintained an enterprise risk management program since 2005. Risk management is an integral part of the Company’s culture. Management’s role is to identify, mitigate, guide and review the efforts of our business units, consider whether the residual risks are acceptable, and approve plans to deal with serious risks. The Board’s role in risk management is to review the performance and functioning of the Company’s overall risk management function and management’s establishment of appropriate systems for managing risk. Specifically, the Board reviews management’s:

• processes to identify matters that create inappropriate risk to achieving our business plans;

• processes to assess the likelihood and impact of such risks in order to prioritize them;

• identification of major risks and how we define “major;”

• identification of primary risk mitigation owners;

• mitigation of major risks, and our view of the resulting residual risk; and

• monitoring of major risks.

     2014 Proxy Statement     9

CORPORATE GOVERNANCE(CONTINUED)

Under the direction of a cross-functional steering committee composed primarily of senior corporate leaders, management provides its feedback on business unit risks during periodic business reviews and annual strategic planning discussions. The enterprise risk management steering 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.

Annually, the Board reviews summary reports that assess the strategic, operational, infrastructure and external risks facing the Company. 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 Board reviews the Company’s “Organization Vitality” in support of its business strategy at least annually. 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 2013, the Board and the Compensation Committee, as well as an ad hoc CEO succession planning committee, met on several occasions 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. More broadly, the Board is regularly updated on key talent indicators for the overall workforce, including diversity, recruiting and development programs.

BOARD LEADERSHIP STRUCTURE

Our Bylaws and Corporate Governance Principles 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 Chairman and our CEO. In February 2010, the Board determined to split the positions of Chairman and CEO. At that time, Mr. O’Connor, who had been independent Lead Director from February 2008 through February 2010, was named Chairman and continues to serve in that capacity. The split of these positions allows Mr. Espe, our President and CEO, to focus on managing the business, while Mr. O’Connor, as Chairman, 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 Company shareholders.

Responsibilities of the Chairman include recruiting new Board members, overseeing the evaluation and compensation of the CEO, ensuring an appropriate succession plan, overseeing independent evaluation of risk, coordinating Board meeting schedules and agenda, chairing and leading the discussions at the meetings, and overseeing the annual performance evaluations of the Board, its committees and its individual members. The Chairman ensures information provided by management to the Board is sufficient for the Board to fulfill its duties and communicates with other directors on key issues and concerns outside of regularly scheduled meetings. The Chairman is also responsible for ensuring the effective functioning of the committees through appropriate delegation to, and membership of, the committees. Finally, the Chairman provides effective leadership for our independent directors to facilitate the independent oversight required by our Bylaws and Corporate Governance Principles, including by ensuring that:

• a majority of our directors are independent;

• all of the members of the Audit Committee, the Compensation Committee and the Governance Committee are independent directors; and

• the Board meets at regularly scheduled executive sessions, outside of the presence of management and those directors not deemed to be Independent Directors (as defined in our Articles and Bylaws) by the Board. Mr. O’Connor, our Chairman, presides at these sessions. In addition, each of the Board’s three standing committees regularly meet at similar executive sessions, at which the respective committee Chairs preside.

COMMUNICATION WITH THE BOARD

Any person who wishes to communicate with the Board, nonemployee directors as a group, or individual directors, including the Chairman, may direct a written communication to the attention of the Corporate Secretary at the Company’s corporate offices at 2500 Columbia Avenue, Lancaster, Pennsylvania 17603. The Corporate Secretary will forward these communications to the intended recipient director(s). You may also send general messages to directors by email todirectors@armstrong.com. If you wish to send an email message to the Governance Committee, including a recommendation regarding a prospective director, please send the message to the CorpGovernance@armstrong.com. The Corporate Secretary will forward these messages, as appropriate.

BOARD MEETINGS AND COMMITTEES

The Board met seven times during 2013. In addition, the disinterested Board members met once in connection with the repurchase and secondary offering transactions in September 2013.

There are three standing committees of the Board: the Audit Committee, the Compensation Committee, and the Governance Committee, 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 U.S. Securities and Exchange Commission (the “SEC”), and the Internal Revenue Service, and under our Articles 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 on the recommendation of the Governance Committee. The Company’s Corporate Governance Principles provide that (i) directors who are currently fully employed should not serve on more than two other corporate boards and (ii) other directors should not serve on more than four other corporate boards. The Board, after considering the circumstances of Mr. Roberts’ service on three other public company audit committees, determined that such service does not impact his ability to effectively serve on the Audit Committee.

All director nominees who served on the Board during 2013 participated in at least 75% of all meetings of the Board and meetings of the Committees on which they served. The average attendance of all directors during 2013 was 96%. Board members are expected to attend annual meetings in person or virtually, via the Internet.

Audit Committee    The Audit Committee met five times during 2013. The members of the Audit Committee are John J. Roberts (Chair), Tao Huang and Larry S. McWilliams. Under its charter, the Audit Committee:

• oversees (i) auditing and accounting matters, including the selection, supervision and compensation of the Company’s independent registered public accounting firm and other independent auditors, (ii) the scope of the annual audits, non-audit services performed by the Company’s independent registered public accounting firm, and (iii) the Company’s accounting practices and internal accounting controls;

• has sole authority to engage, retain and dismiss the independent registered public accounting firm;

• reviews and discusses with management and our independent registered public accounting firm the annual audited financial statements and quarterly financial statements included in our SEC filings;

• assists the Board in monitoring the integrity of the Company’s financial statements and the independent registered public accounting firm’s qualifications, independence and performance;

• considers risks associated with overall financial reporting, legal compliance and disclosure processes; and

• supervises and reviews the effectiveness of the Company’s internal audit and legal compliance functions and compliance by the Company with legal and regulatory requirements.

Each member of the Audit Committee meets the NYSE and SEC financial literacy requirements. The Board has determined that at least one member of the Audit Committee, Mr. Roberts, qualifies as an “Audit Committee Financial Expert” as defined in the Exchange Act. The Audit Committee regularly meets independently with the Company’s internal and independent auditors, with the leaders of the Company’s compliance function, and with management.

Management Development and Compensation Committee The Compensation Committee met seven times during 2013. The members of the Compensation Committee are Stan A. Askren (Chair), James J. Gaffney, Larry S. McWilliams and James C. Melville. Under its charter, the Compensation Committee:

• oversees the design of our executive compensation and benefit programs and employment practices;

• administers and makes recommendations regarding our incentive and equity compensation plans;

• reviews and approves corporate goals and individual objectives relevant to the compensation of the CEO and evaluates the CEO’s performance relative to those goals and objectives, and recommends CEO compensation to the independent directors based on the evaluation;

• oversees the evaluation of the other executive officers and establishes their compensation levels in collaboration with the CEO;

• reviews incentive compensation to confirm that such compensation does not encourage unnecessary risk-taking; and

• monitors senior management succession planning.

Nominating and Governance Committee The Governance Committee met four times during 2013. The members of the Governance Committee are James J. Gaffney (Chair), James J. O’Connor and John J. Roberts. Under its charter, the Governance Committee:

• monitors the independence of nonemployee directors;

• reviews and evaluates director candidates and makes recommendations to the Board concerning nominees for election as Board members;

• establishes criteria for the selection of candidates to serve on the Board;

• recommends directors for appointment to Board committees;

• makes recommendations to the Board regarding corporate governance matters;

• reviews and makes recommendations to the Board regarding the compensation of nonemployee directors;

• oversees the Company’s director education and orientation programs; and

• coordinates an annual evaluation of the performance of the Board and each committee.

Other Committees    In addition to the three standing committees described above, members of the Board regularly meet on an ad hoc basis to discuss and approve matters through other committees that have been previously established by the Board. Such committees address such matters as refinancing, succession planning and crisis response. In connection with the Company’s secondary public offering and repurchase transactions during 2013, the Board established a pricing committee which met several times to review and approve the terms of those transactions.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

None of the members of the Compensation Committee has ever been an officer or employee of the Company or its subsidiaries, or had any relationship with the Company that requires disclosure under applicable SEC regulations.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

Any related party transaction that may arise is required to be reviewed and approved by the Governance Committee, who must have no connection with the transaction. Related party transactions would include transactions by the Company or any subsidiary with any director, director nominee, executive officer, shareholders owning more than 5% of the Company’s outstanding shares of our common stock, par value $0.01 per share (“Common Shares”), or immediate family member of any of the foregoing, and transactions with businesses affiliated with any director or director nominee that meet the specifications in Item 404 of Regulation S-K under the Exchange Act. The Chair of the Governance Committee has authority to approve transactions involving sums less than the disclosure threshold set in Item 404. The material details of any such matters are required to be disclosed to the Governance Committee at its next regular meeting.

SHAREHOLDER-RECOMMENDED DIRECTOR CANDIDATES

The Governance Committee will consider director candidates nominated by shareholders. The procedures for recommending candidates are posted at www.armstrong.com/corporatena/article9748.html under “About Armstrong” and “Corporate Governance.” Shareholders who wish to suggest individuals for service on the Board are requested to review the following documents posted on this site: “Process for Evaluation of Director Candidates,” “Director Responsibilities and Qualifications,” and “Position Description for an Armstrong Director.” Shareholders should write to the Corporate Secretary at the Company’s corporate offices at 2500 Columbia Avenue, Lancaster, Pennsylvania 17603 and supply the following information:

• the full name, address, education and professional experience of the proposed nominee and a statement explaining why this person would be a good director;

• the consent of the proposed nominee to be considered and to serve, if elected;

• the proposed nominee’s own self-assessment of qualifications and independence under SEC, NYSE rules and our Corporate Governance Principles; and

• the number of Common Shares held by both the proposed nominee, and by the person(s) supporting the proposed nominee.

When evaluating the candidacy of nominees proposed by shareholders, the Governance Committee also considers the number of shares owned by the nominating shareholder, as well as each nominee’s responses to the Company’s prospective director questionnaire, the presence or absence of any conflicts of interest, and background information. There have been no changes to the procedure by which shareholders may recommend nominees to the Board within the past year.

COMPENSATION OF DIRECTORS

In establishing director compensation, 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. The Board is 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 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.

In April 2013, the Governance Committee reviewed the compensation program for nonemployee

directors, including the 2008 Directors Stock Unit Plan, as amended (“Directors Stock Unit Plan”). The review included an analysis of competitive market data and any underlying director compensation trends with assistance from an independent compensation consultant, Frederic W. Cook & Co. (“Cook & Co.”). Following that review, and a recommendation by the Governance Committee, the Board approved an increase of $5,000 to each annual retainer fee (cash and equity) for directors, and a $10,000 increase to each annual retainer fee (cash and equity) for the Chair, all effective June 21, 2013. On average, the total compensation levels, as well as cash and equity compensation levels, for our nonemployee directors approximated the 75^th percentile, on a per director basis.

The following table describes the elements of the compensation program for nonemployee directors:

2013 Director Compensation Program (effective – June 21, 2013)

Element	Amount	Terms
Annual Retainer (Cash)	$  90,000 $190,000 (Chair)	paid in quarterly installments, in arrears
Annual Retainer (Equity)	$105,000 $205,000 (Chair)	annual (or pro-rated) grant of restricted stock units •   Directors Stock Unit Plan •   vest at one year anniversary or earlier change in control if serving on such date •   pre-2011 grants deliverable six months following end of service (except removal for cause) •   2011 and later grants deliverable on date of end of service (except removal for cause) •   one share per one unit upon delivery •   no voting power until delivered •   dividend equivalent rights
Committee Chair Fees	$20,000 (AC; MDCC) $10,000 (NGC)	paid in quarterly installments, in arrears
Special Assignment Fees	$2,500 per diem ($1,250 for less than four hours)	may be paid in connection with: •   one-on-one meetings with the CEO •   plant visits •   other non-scheduled significant activities

* Committees: AC (Audit); MDCC (Management Development & Development); NGC (Nominating & Governance)

Annual grants for the equity portion of the retainer are effective as of the first business day following the date of the Annual Shareholders’ Meeting, and

the amount of each grant is determined by the NYSE closing price of our Common Shares on that date.

(1) The Board approved a $5,000 increase to the annual equity retainer, effective June 21, 2013. Represents amounts that are in units of our Common Shares. The amounts reported represent the aggregate grant date fair value for restricted stock units granted during the fiscal year, as calculated under the Financial Accounting Standards Board’s Accounting Standards Codification Topic 718. Under ASC Topic 718, the grant date fair value is calculated using the closing market price of our Common Shares on the date of the grant. For the number of stock units credited to each director’s account as of March 31, 2014, see SECURITIES OWNERSHIPOF CERTAIN BENEFICIAL OWNERS, MANAGEMENTAND DIRECTORS on page 17.

(2) The directors do not receive stock options as part of their compensation for service on our Board.

(3) There is no plan or arrangement for directors to defer the compensation that they receive as part of their compensation for service on our Board.

(4) Reflects incremental costs incurred by the Company for spouse travel and lodging at the February 2013 Board meeting. Mr. Melville’s amount also reflects the amount he received for special assignment fees in connection with certain non-scheduled significant activities and projects.

(5) Mr. Liaw received a pro-rated payment of the first quarterly installment of the 2013 annual cash retainer in March 2013 following the Board’s determination on February 15, 2013 that, as a result of Mr. Liaw’s new position as CFO of FleetPride, Inc. and corresponding separation from TPG, effective on that date, he would become a participant in the nonemployee directors’ compensation program.

Stock Ownership Guidelines

In accordance with our Corporate Governance Principles, each nonemployee director must acquire and then hold until six months following the end of his service, phantom units and/or Common Shares equal in value to three times the director’s annual retainer at the time he joined the Board. Directors endeavor to reach that level of ownership within five years of joining the Board. With the exception of

Messrs. Melville and Liaw, all of the current directors have already achieved this ownership requirement. Mr. Espe is an officer of the Company and, therefore, not subject to the stock ownership guidelines for nonemployee directors. Mr. Melville served on our Board from 2009 to 2010 and was reappointed to our Board in February 2012. Mr. Liaw first became eligible to participate in the nonemployee director compensation program in February 2013.

ITEM 2 – RATIFICATION OF THE APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee selected KPMG LLP to audit our consolidated financial statements and our internal control over financial reporting for 2014. In accordance with past practice, this selection will be presented to the shareholders for ratification at the annual meeting; however, consistent with the requirements of the Sarbanes-Oxley Act of 2002, the Audit Committee has ultimate authority in respect of the selection of our independent registered public accounting firm. The Audit

Committee may reconsider its selection if the appointment is not ratified by the shareholders.

A representative of KPMG LLP will be in attendance at the annual meeting to respond to appropriate questions and will be afforded the opportunity to make a statement at the meeting, if he or she desires to do so.

THE BOARD OF DIRECTORS RECOMMENDS THAT SHAREHOLDERS VOTEFOR THE RATIFICATION OF THE APPOINTMENT OF KPMG LLP.

     2014 Proxy Statement     19

AUDIT COMMITTEE REPORT

The Audit Committee engaged KPMG LLP as the Company’s independent registered public accounting firm for 2013. In making this selection, the Audit Committee considered KPMG LLP’s qualifications, discussed with KPMG LLP its independence, and reviewed the audit and non-audit services provided by KPMG LLP to the Company.

Management of the Company has primary responsibility for preparing the Company’s financial statements and establishing effective internal control over financial reporting. KPMG LLP is responsible for auditing those financial statements and expressing an opinion on the conformity of the Company’s audited financial statements with accounting principles generally accepted in the United States and on the effectiveness of the Company’s internal control over financial reporting based on the criteria established in 1992 by the Committee of Sponsoring Organizations of the Treadway Commission. Accordingly, the Audit Committee reviewed and discussed the audited consolidated financial statements for fiscal 2013 with the Company’s management. The Audit Committee also reviewed and discussed with management the critical accounting policies applied by the Company in the preparation of those financial statements. The Audit Committee also discussed with KPMG LLP the matters required to be discussed by applicable standards of the Public Company Accounting Oversight Board, and had the opportunity to ask KPMG LLP questions relating to such matters. The discussions included the quality, and not just the acceptability, of the accounting principles utilized, the reasonableness of significant accounting judgments, and the clarity of disclosures in the financial statements.

The Audit Committee considers the independence, qualifications and performance of KPMG. Such consideration includes reviewing the written disclosures and the letter received from KPMG required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent registered public accountants’ communications with the Audit Committee concerning independence, and discussing with KPMG their independence.

Based on the reviews and discussions referred to above, the Audit Committee recommended to the Board that the audited consolidated financial statements be included in Armstrong’s Annual Report on Form 10-K for the year ended December 31, 2013. The Audit Committee has also engaged KPMG as the Company’s independent registered public accounting firm for 2014. The Audit Committee and the Board believe that the continued retention of KPMG to serve as the Company’s independent registered public accounting firm is in the best interests of the Company and its shareholders and have recommended that shareholders ratify the appointment of KPMG as the Company’s independent registered public accounting firm for the fiscal year 2014.

FEES PAID TO INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The following table presents fees for professional audit services rendered by KPMG LLP for the audit of our annual consolidated financial statements for 2013 and 2012 and fees billed for other services rendered by KPMG LLP. All fees in 2013 and 2012 were pre-approved by the Audit Committee.

Total Fees	$	5,908	$	4,967

(1) Audit Fees are for services rendered in connection with the integrated audit of Armstrong’s consolidated financial statements as of and for the year, for which a portion of the billings occurred the following year. Audit fees were also incurred for reviews of consolidated financial statements included in Armstrong’s quarterly reports on Form 10-Q, services normally provided in connection with statutory and regulatory filings, and services for comfort letters.

(2) Audit Related Fees consisted principally of fees for audits of financial statements of certain employee benefit plans, agreed-upon procedures, accounting research assistance on technical topics and other matters with respect to non-U.S. statutory financial statements.

(3) Tax Fees were primarily for preparation of tax returns in non-U.S. jurisdictions, assistance with tax audits and appeals and other tax consultation and compliance services.

The Audit Committee has considered whether the provision by KPMG LLP of the non-audit services described above was allowed under Rule 2-01(c)(4) of Regulation S-X and was compatible with maintaining auditor independence, and has concluded that KPMG LLP was and is independent of the Company in all respects.

Audit Committee Pre-Approval Policy

The Audit Committee adheres to a policy that requires the Audit Committee’s prior approval of any audit, audit-related and non-audit services provided by the firm that serves as our independent registered public accounting firm. Pursuant to this policy, management cannot engage the firm for any services without the Audit Committee’s pre-approval. The Audit Committee delegates to the Audit Committee Chair the authority to pre-approve non-audit services not exceeding 5% of the total audit fees for the year for purposes of handling immediate needs, with a report to the full Audit Committee of such approvals at its next meeting. The policy complies with Section 10A(i) of the Exchange Act.

COMPENSATION DISCUSSION AND ANALYSIS

INTRODUCTION

This compensation discussion and analysis (“CD&A”) includes a detailed description of our executive compensation philosophy and programs, which is generally applicable to all of our management employees. However, this CD&A focuses primarily on the material components of our executive compensation program as they apply to our NEOs, who, in 2013 were⁽¹⁾:

Matthew J. Espe President and CEO

David S. Schulz⁽²⁾ Senior Vice President and CFO

Thomas B. Mangas⁽³⁾ Executive Vice President and CEO, Armstrong Floor Products (“AFP”) and former Senior Vice President and CFO

Victor D. Grizzle Executive Vice President and CEO, Armstrong Building Products (“ABP”)

Donald R. Maier⁽⁴⁾ Senior Vice President, Global Operations Excellence

Mark A Hershey Senior Vice President, General Counsel and Secretary, and Chief Compliance Officer

Frank J. Ready⁽⁵⁾ Former Executive Vice President and CEO, Armstrong Floor Products

(1) We determined the above NEOs for 2013 in accordance with SEC rules, which require that we include: all individuals who served as our principal executive officer (Mr. Espe) and principal financial officer (Messrs. Schulz and Mangas), regardless of compensation level during the year; our three most highly compensated executive officers other than the principal executive officer and principal financial officer who were serving as executive officers at the end of the last completed fiscal year (Messrs. Grizzle, Maier and Hershey); and up to two additional individuals for whom disclosure would have been provided under the applicable rules except for the fact that the individual was not serving as an executive officer at the end of the last completed fiscal year (Mr. Ready).

(2) Mr. Schulz joined us in June 2011 and has served as our CFO since November 2013;

(3) Mr. Mangas served as CFO between 2010 and November 2013, and has served as our global AFP leader since November 2013;

(4) Mr. Maier’s role as SVP, Global Operations Excellence will terminate on December 31, 2014 and he will provide transition services to us until February 28, 2015 per a Transition Agreement filed with the SEC on Form 8-K on April 4, 2014.

(5) Mr. Ready served as our global AFP leader until November 2013 and retired effective December 31, 2013.

Executive Summary

Our Business

We are a global leader in the design and manufacture of floors and ceilings. As of December 31, 2013, we operated 35 plants in eight countries and had approximately 8,500 employees worldwide. For more information about our business, please see “Business” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K filed with the SEC on February 24, 2014.

Executive Compensation Programs

Our executive compensation programs are designed to attract and retain high caliber talent, reward performance and align with the interests of our shareholders. We execute this philosophy through the payment of base salaries, cash

incentive awards under our Management Achievement Plan (“MAP”), and grants of a combination of time-based and performance-based restricted stock units (“RSU” and “PSU”, respectively) and stock options under our 2011 Long-Term Incentive Plan (“LTIP”).

To focus our NEOs on delivering both short- and long-term results, a significant amount of their target total direct compensation (“TDC”, composed of base salary, short-term and long-term incentive compensation) mix is dependent upon achieving specified results and is, therefore, “at risk”. We also employ specific policies and practices to supplement our compensation philosophy, including:

• Stock ownership guidelines to ensure that NEOs have significant exposure to changes in our stock price, thereby aligning NEO and long-term shareholder interests.

22          2014 Proxy Statement

COMPENSATION DISCUSSION AND ANALYSIS(CONTINUED)

• Recoupment policy applicable to short- and long-term incentive awards that enables us to exercise discretion and take action to recoup the amount of any cash or stock-based awards in the event we are required to prepare an accounting restatement due to a material noncompliance with any financial reporting requirement under the securities laws as a result of fraud, misconduct, or gross negligence. To the extent that the SEC may adopt future rules for clawback policies that require changes to our policy, we will revise our policy accordingly.

• Policy prohibiting derivative transactions in our Common Shares, including: trading in puts, calls, covered calls, or other derivative products involving our securities; engaging in any hedging or monetization transaction with respect to our securities; or, holding company securities in a margin account or pledging our securities as collateral for a loan.

• We do not have any plans or agreements that provide tax gross-ups under Section 280G of the Code to our NEOs.

2013 Business Highlights

In 2013, we focused on growing our core businesses in established and emerging markets and continued our disciplined effort to create a lean and productive culture while facing challenging market conditions.

Key performance highlights included:

• Earnings Before Interest, Taxes, Depreciation and Amortization (“EBITDA”)* of $371 million was down 7.7 percent from 2012 due to increases in manufacturing and input costs driven by rising lumber prices as well as higher SG&A expenses.

• Consolidated net sales increased by $101 million, or 4 percent. The increase was driven by higher volumes and pricing in Wood Flooring and higher volumes across all geographies in ABP, with pricing, volume and mix all positive at a consolidated level.

• $68 million of Free Cash Flow (“FCF”), which was lower than 2012, primarily due to lower cash earnings and higher capital expenditures which were only partially offset by improvements in working capital and lower cash interest expense when compared to the prior year.

• Unadjusted return on invested capital (“ROIC”), (as reported), was 8.2%, a decrease of 130 basis points over 2012 and, while lower than 2012, was the second highest since emergence from bankruptcy in 2006.

• Despite lower earnings, our share price increased by 6.5 percent.

We also made significant progress with respect to a variety of strategic, financial and operational initiatives.

• We strengthened our Balance Sheet.

• We bought back approximately 5 million shares for approximately $261 million.

• We refinanced our senior credit facility to extend maturities and lower future cash interest expense.

• We continued to make significant progress with our plant construction projects.

• We completed construction of three plants in China: a homogeneous flooring plant, a heterogeneous flooring plant, and a mineral fiber ceilings plant.

• We began construction of our first mineral fiber ceilings plant in Russia and continued to expand our new ceiling distribution center.

• We announced a $41 million investment to manufacture luxury vinyl tile in the U.S.

• We significantly increased our focus on new product development and commercialization.

• We realized approximately 31% of our sales from products introduced in the past five years.

• We implemented new procedures to increase the quantity of invention submissions and prioritize them so that patent filings are aligned with R&D and business unit strategies.

• Overall, the Compensation Committee believed that we made progress in many areas, but fell short of our aspirational EBITDA goal.

* Continuing operations basis. Please refer to Annex A for a reconciliation of Adjusted EBITDA to U.S. GAAP.

COMPENSATION DISCUSSION AND ANALYSIS(CONTINUED)

2013 Executive Compensation Highlights

Our 2013 EBITDA performance resulted in a 78% MAP payout factor at the Consolidated level, 22% below target. NEOs received between 23% and 105% of target.

Our three-year cumulative ROIC performance (2011 – 2013 PSU plan) resulted in a 57% payout factor, 43% below target, reflecting actual performance relative to an aspirational goal that we did not achieve.

Further, during 2013, our Compensation Committee did not make significant changes to executive compensation but completed the following key activities:

• Established EBITDA as the sole performance metric against which to measure and reward for annual performance in 2013.

• Eliminated FCF as a metric in the MAP.

• Approved a “stretch” EBITDA target of $420 million and established a corresponding payout factor for achieving “stretch” at 125 percent.

• Approved 2013 MAP payments below target in line with below target performance.

• 78% (Consolidated)

• 23% (AFP)

• 105% (ABP)

• Retained Towers Watson as the Committee Consultant.

• Reviewed and confirmed our compensation philosophy and strategy.

• Conducted an in-depth review of long-term performance metrics under our LTIP and confirmed ROIC as the metric for the 2014-2016 PSU plan.

The table below summarizes TDC awarded to our NEOs during 2013. This table is not intended to be a substitute for the Summary Compensation Table (‘‘SCT’’) or Grants of Plan-Based Awards Table (‘‘GPBAT’’).

Consideration of Last Year’s Advisory

Shareholder Vote on Executive Compensation

Our 2013 Annual Meeting of Shareholders did not include an advisory shareholder vote on executive compensation.

At our 2011 Annual Meeting of Shareholders, our shareholders expressed a preference that advisory votes on executive compensation occur every three years. In accordance with the results of this vote,

24          2014 Proxy Statement

COMPENSATION DISCUSSION AND ANALYSIS(CONTINUED)

the Board determined to implement an advisory vote on executive compensation every three years until the next required vote on the frequency of shareholder votes on the compensation of executives, which is scheduled to occur at the 2017 annual meeting. Accordingly, our next advisory shareholder vote on executive compensation will take place at this Annual Meeting.

The Board and the Compensation Committee appreciate and value the views of our shareholders. In considering the results of the 2011 favorable (92%) advisory vote on executive compensation, the Compensation Committee noted that our current executive compensation program has been effective in implementing our stated compensation philosophy and objectives.

The Compensation Committee recognizes that executive pay practices and notions of sound governance principles continue to evolve. While no specific changes were implemented as a result of the vote, the Compensation Committee intends to continue to pay close attention to the advice and counsel of its compensation advisors and invites our shareholders to communicate any concerns or opinions on executive pay directly to the Compensation Committee or the Board. Please refer to “Communication with the Board” on page             for information about communicating with the Board.

PHILOSOPHY AND OBJECTIVES OF OUR EXECUTIVE COMPENSATION PROGRAM

Our long-term success and growth depend on highly capable global leaders with the experience

and skills to deliver against 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. Generally, the same principles that apply to our NEOs also apply to the compensation of our salaried employees. In developing and maintaining our executive compensation program, the Compensation Committee focuses on the following key objectives:

• Align executive interests with shareholders’ interests.

• Create a strong link between pay and performance by placing a significant portion of compensation ‘‘at risk’’ based on performance against pre-established goals.

• Structure sufficiently competitive compensation packages globally, to enable access to high-quality executives in a highly competitive talent environment.

HOW WE MAKE COMPENSATION DECISIONS

The Compensation 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 Compensation Committee solicits input from the independent members of the Board, the CEO and other members of management, and its independent compensation consultant to assist it with its responsibilities. The following summarizes the roles of each of the key participants in the executive compensation decision-making process.

COMPENSATION DISCUSSION AND ANALYSIS(CONTINUED)

Independent Compensation Consultant

In July 2013, the Compensation Committee retained Towers Watson as its independent consultant on executive compensation matters. Prior to Towers Watson, the Compensation Committee was advised by Cook & Co.

Towers Watson serves as our Pension Plan Actuary in Canada (an arrangement that has been in place for several years, prior to Towers Watson becoming the Compensation Committee’s consultant) and typical annual fees are $300,000. In early 2013, prior to becoming the advisor to the Compensation Committee, Towers Watson provided sales compensation consulting services for a fee of $120,000. We also purchase select compensation and HR survey data from the firm. Towers Watson does not perform any other services for us. At the request of the Compensation Committee, in addition to providing general executive compensation advice outlined above, Towers Watson performed the following services during 2013:

• Led an in-depth discussion on our executive compensation strategy and how executive compensation programs align with our strategic business objectives.

• Advised on the design considerations with respect to the 2014 MAP and the 2014 LTIP, to ensure appropriate linkage between short- and long-term performance and pay and performance.

• Provided a detailed market data analyses for the NEOs.

• Advised the Compensation Committee on setting the CEO’s compensation.

The Compensation Committee has determined that the work of Towers Watson did not raise any conflicts of interest in 2013. In making this assessment, the Compensation Committee

considered the independence factors enumerated in Rule 10C-1(b) under the Exchange Act, including the fact that Towers Watson provides limited other services to us, the level of fees received from us as a percentage of Towers Watson’s total revenue, policies and procedures employed by Towers Watson to prevent conflicts of interest, and whether the individual Towers Watson advisers to the Compensation Committee own any Common Shares or have any business or personal relationships with members of the Compensation Committee or our executive officers.

After considering all of the factors required by the NYSE rules, the Compensation Committee is satisfied with Towers Watson’s independence.

Use of Competitive Data

In setting NEO compensation, the Compensation Committee considers various types of information, including survey data, peer compensation data, tally sheets, wealth accumulation analyses and related benchmark information.

Annual Compensation Benchmarking

Annually, the Compensation Committee reviews all components of NEO compensation versus competitive market data.

In general, we target NEO pay to be at or near the 50^th percentile of the competitive market, but we may exceed this target due to an individual’s performance, internal equity with peers situated at similar levels, and to attract the required level of global business knowledge and leadership needed to achieve our strategy.

The principal sources of market data include (combined “Competitive Market”):

• Survey data (all NEOs), including surveys by AonHewitt and Towers Watson (“Market”)

• Peer Group data (CEO and CFO) (“Peer Group”)

     2014 Proxy Statement     27

COMPENSATION DISCUSSION AND ANALYSIS(CONTINUED)

Peer Group

The Compensation Committee uses compensation data compiled from a group of peer companies based on several criteria, including business model comparability, company size measured by revenues and market capitalization, and competition for executive talent and investor capital. The 2013 Peer Group consists of 16 manufacturing companies in the building and construction industries and is reflected in the table below:

Acuity Brands, Inc.	Masco Corporation	Sherwin-Williams Company
W. R. Grace & Company	Herman Miller, Incorporated	Steelcase, Incorporated
Leggett & Platt, Inc.	Mohawk Industries, Inc.	Universal Forest Products, Inc.
Lennox International Inc.	Nortek, Inc.	USG Corporation
Louisiana-Pacific Corporation	Owens Corning	Vulcan Materials Company
Martin Marietta Materials

Our revenues and market capitalization approximate the Peer Group median.

Tally Sheets and Wealth Accumulation Analyses

The Compensation Committee uses tally sheets and wealth accumulation analyses when evaluating compensation-related decisions for each NEO.

• Tally sheets provide historic information on each executive’s equity and non-equity compensation, and other compensation such as potential payments upon termination of employment.

• Wealth accumulation analysis assesses the total Armstrong-specific wealth that could be earned by each NEO given certain stock price assumptions.

Compensation Mix

To facilitate the link between NEO pay and company performance, a significant amount of TDC is performance-based and “at risk.”

81% of our CEO’s target TDC and 70% of the average target TDC of our other NEOs is performance-based and “at risk”.

Alignment of Compensation Elements and Objectives

The following table illustrates how our executive compensation elements align with our compensation objectives:

2013 COMPENSATION DESIGN AND OUTCOMES

Base Salary

The Compensation Committee’s decision on 2013 base salaries was largely driven by the competitiveness of each NEO’s base salary compared to the Competitive Market. Unless noted below, increases were effective April 1, 2013. With exception of Mr. Schulz, the table below represents the base salary rate as of December 31. This information differs from the SCT, which reflects the total base salary received for the year.

(3) Standard merit increase and performance-based adjustment

(4) Standard merit increase

(5) Standard merit increase and market-based adjustment

Management Achievement Plan

MAP awards provide an annual incentive opportunity for achieving financial results based on performance goals tied to our annual operating plan.

Each NEO’s target MAP opportunity (expressed as a percent of base salary) is based on role responsibility, alignment with similar positions internally, and external Competitive Market. Actual payout will vary with actual business performance relative to performance targets.

MAP awards were determined based on the following formula, measures and weightings. The Compensation Committee approves these factors at the beginning of each fiscal year. Additional details follow below the table.

2013 MAP Design

30          2014 Proxy Statement

COMPENSATION DISCUSSION AND ANALYSIS(CONTINUED)

2013 Target MAP

2013 Target MAP opportunity for our NEOs were as set forth in the table below. With the exception of Mr. Schulz, who was promoted into his role effective November 16, 2013, there were no changes to these targets from 2012.

Name	Target MAP Opportunity %	Target MAP $
Mr. Espe	100%		980,000
Mr. Schulz(1)	40% / 75%		122,665
Mr. Mangas	75%		386,250
Mr. Grizzle	75%		344,531
Mr. Maier	50%		204,500
Mr. Hershey	60%		248,250
Mr. Ready	75%		375,000

(1) Mr. Schulz’ target increased from 40% to 75% upon his role change in November 2013. The $122,665 reflects his actual target for 2013 based on the split role.

After a review of competitive market data provided by Towers Watson, the Compensation Committee set Mr. Espe’s 2014 MAP target at 110% of base salary.

2013 MAP Performance Metrics and Weighting

The Compensation Committee selected EBITDA (for both the Consolidated as well as at the Business Unit level) as the 2013 MAP performance metric. The Compensation Committee believes that EBITDA aligns to key elements of our operating plan and is a good measure of operating performance (pre-financing and pre-tax).

In establishing MAP performance and payout ranges for the Company, AFP and ABP, the Compensation Committee considered a number of factors:

• The amount of year over year improvement in EBITDA required to achieve target

• The degree of difficulty and probability of achieving the various EBITDA performance targets

• Considering the degree of difficulty built into the 2013 operating plan targets, the Compensation Committee established a payout factor of 125% for achieving target performance

• The percent of incremental EBITDA to be split between participants and shareholders

The MAP opportunity for NEOs with primary responsibilities at the Corporate level is weighted 100% to Consolidated results. NEOs with business unit responsibilities are weighted 30% to Consolidated results and 70% to the individual business unit.

Mr. Mangas became CEO of AFP in November 2013; however, since the majority of his time in 2013 was spent in the CFO role, his 2013 MAP was weighted 100% to Consolidated results. Mr. Schulz spent the majority of 2013 in the role of CFO for ABP, and, accordingly, his 2013 MAP was weighted 30% to Consolidated and 70% to ABP.

Weighting	Consolidated		Business Unit
Mr. Espe		100%
Mr. Schulz		30%	70% (ABP)
Mr. Mangas		100%
Mr. Grizzle		30%	70% (ABP)
Mr. Maier		100%
Mr. Hershey		100%
Mr. Ready		30%	70% (AFP)

Individual Performance

The Board and the Compensation Committee considered individual performance when finalizing MAP awards for the CEO and other NEOs, respectively; however, no individual performance adjustments were made in determining the final 2013 MAP awards. Any individual performance adjustment cannot exceed the maximum level determined by EBITDA performance.

2013 Final Performance and Payout Factors

Our 2013 EBITDA performance resulted in a 78% MAP payout factor at the Consolidated level.

Further details are shown in the table below:

EBITDA	2013 Target $M		2014 Actual $M*		Performance %		Payout %
Consolidated		420		379		90%		78%
AFP		158		112		71%		0%
ABP		326		323		99%		117%

* Please refer to Annex A for a reconciliation of Adjusted EBITDA to U.S. GAAP. We achieved full year adjusted

COMPENSATION DISCUSSION AND ANALYSIS(CONTINUED)

EBITDA of $379 million after giving effect to the specific items that the Compensation Committee pre-determined in February 2013 were eligible for exclusion from the achievement calculation.

2013 Final MAP Awards

The Compensation Committee determined the final 2013 MAP by multiplying the NEO’s target MAP amount by the final weighted payout factors, as outlined below.

For NEOs, who are weighted 100% to Consolidated results, the Compensation Committee approved a final payout factor of 78%.

NAME	Target MAP $		Payout Factor		2013 Final MAP Award $
Mr. Espe		980,000		78%		764,400
Mr. Mangas		386,250		78%		301,300
Mr. Maier		204,500		78%		159,600
Mr. Hershey		248,250		78%		193,700

For NEOs, who are weighted 30% to Consolidated results and 70% to Business Unit results, the Compensation Committee approved a final payout factor of 23% for Mr. Ready and 105% for Mr. Grizzle and Mr. Schulz.

NAME	Target MAP $		Weighted Cons. Payout Factor (wtd. 30%)		Weighted Business Unit Payout Factor (wtd. 70%)		2013 Final MAP Payout Factor %		2013 Final MAP Award $
Mr. Ready		375,000		23%		0%		23%		86,300
Mr. Grizzle		344,531		23%		82%		105%		361,800
Mr. Schulz		122,665		23%		82%		105%		128,900

Long Term Incentive Plan

The goal of the LTIP is to provide equity-based long-term incentive awards that link management interests to shareholder returns and focus management on our long-term performance.

In determining long-term incentive award opportunity for the CEO and other NEOs, the Board and the Compensation Committee generally consider a number of factors, including Competitive Market, internal equity, and cost (dilution and accounting cost) and also take into consideration tally sheet and wealth accumulation analyses.

LTIP awards are typically made two business days following the release of our prior fiscal year’s fourth quarter and full year financial results. This allows sufficient time for the market to absorb the announcement of earnings.

In 2013, our LTI awards for NEOs consisted of 60% non-qualified stock options and 40% PSU.

2013 Target LTIP

The Compensation Committee annually determines LTIP target opportunity (expressed as a percent of base salary) based on role responsibility, alignment with similar positions internally, and external Competitive Market, as well as a review of tally sheets and wealth accumulation analyses.

The respective target percentages for LTIP grants to our NEO’s in 2013 and the resulting Grant Date Fair Value were as set forth in the table below.

Name	2013 LTIP Target as % of Base Salary		2013 LTIP - Grant Date Fair Value $(1)
Mr. Espe		321%		3,150,000
Mr. Schulz(2)		55%		129,700
Mr. Mangas		200%		1,000,000
Mr. Grizzle		180%		810,000
Mr. Maier		150%		600,000
Mr. Hershey		140%		553,000
Mr. Ready		200%		1,000,000

(1) Amounts represent the grant date fair value for the long-term incentive equity award granted in February 2013, as calculated under the Financial Accounting Standards Board’s Accounting Standards Codification Topic 718. Under ASC Topic 718, the grant date fair value is calculated using the closing market price of our Common Shares ($51.76) on the date of the grant (February 20, 2013.).

(2) Reflects Mr. Schulz’s 2013 LTIP award relative to his previous role.

After a review of competitive market data provided by Towers Watson, the Compensation Committee set Mr. Espe’s 2014 LTI award at $3,150,000.

Stock Options

Stock option awards generally have a term of ten years and vest in equal installments on each of the first three anniversaries of the date of grant. The exercise price is based on the closing price of our Common shares on the NYSE on the date of grant.

32          2014 Proxy Statement

COMPENSATION DISCUSSION AND ANALYSIS(CONTINUED)

The number of non-qualified stock options granted to each NEO was determined using a Black-Scholes value of $21.61. On the effective date of the grant, the exercise price for the stock options was $51.76.

The assumptions used to determine the valuation of our option awards can be found in the footnote section of the GPBA table.

Performance-based Awards

In 2013, the Compensation Committee established ROIC as the single financial measure for the 2013 – 2015 PSU program. ROIC aligns to our strategic plan and correlates to stock price performance over a multi-year performance period. ROIC also serves as a measure for tracking management’s performance in generating the required return on previously invested capital, and in effectively allocating capital to profitable investments during the three-year performance period.

Three-Year Cumulative ROIC Performance Targets (2013 – 2015)

The actual number of shares earned for the PSUs granted in 2013 will be based on our performance against the internal ROIC target established by the Compensation Committee during the three-year performance period.

	Performance to Target			Payout Opportunity
Threshold		70	%		50	%
Target		100	%		100	%
Maximum		120	%		175	%

ADDITIONAL INFORMATION REGARDING OUR COMPENSATION PROGRAMS

Qualified and Non-qualified Defined Benefit Pension Plans

With exception of Mr. Ready, our NEOs do not participate in the Company’s qualified defined benefit pension plan, the Retirement Income Plan (“RIP”), which was closed to newly hired employees after January 1, 2005.

In addition, a non-qualified defined benefit pension plan, the Retirement Benefit Equity Plan (“RBEP”), pays any benefit that cannot be paid under the RIP

due to statutory limits. Mr. Ready is the only NEO who met the qualifications to remain in the RBEP.

Qualified Defined Contribution Savings Plan and Non-qualified Deferred Compensation Plan

For salaried employees who do not participate in the RIP, we provide a 401(k) match of 100% on the first 4% of employee contributions and a 50% match on the next 4% of employee contributions, up to a maximum company match of $17,500 for 2013. All NEOs, with exception of Mr. Ready are eligible to participate in this program.

Mr. Ready and other employees who remained eligible for RIP and RBEP benefits, are eligible to receive a lower 401(k) match of 50% on 6% of employee contributions up to a maximum company match of $8,750 for 2013.

The company offers an unfunded, nonqualified deferred compensation plan, the Armstrong Nonqualified Deferred Compensation Plan (“NQDCP”), to restore Company contributions that would be lost due to IRC limits on compensation that can be taken into account under the Company’s tax-qualified 401(k) and to allow participants to voluntarily elect to defer some portion of base salary and MAP until a future date.

Participants receive a Company match identical to the 401(k) company match up to a maximum contribution of 6% of eligible earnings. All NEOs with exception of Mr. Ready are eligible to participate in this program.

During 2013, Mr. Ready also participated in a split dollar life insurance policy entered into in 1997. Armstrong ceased paying the premiums on the policy for Mr. Ready in 2006. Armstrong retains a collateral interest in the policy’s cash value equal to the premiums paid by the Company. At Mr. Ready’s 62nd birthday, Armstrong will be reimbursed for amounts paid in premiums for the policy.

Bonus Replacement Retirement Plan (“BRRP”)

The BRRP was established to allow executives to defer a portion of income (up to $20,000) into a qualified, tax-deferred plan. The Company will make a non-elective contribution to the executive’s account, and will have a corresponding reduction in the amount of the MAP payment. Participants’ contributions are exempt from FICA taxation. The

executive may choose from the same investment options provided under the 401(k) plan

Change in Control (“CIC”) Agreements

The Compensation Committee provides individual CIC agreements to the NEOs to establish a competitive level of financial security in the event of a CIC. The Compensation Committee determined the level of CIC benefits for the NEOs based on research conducted by Cook & Co. in 2010 and an assessment of contemporary market practices.

The CIC agreements are subject to restrictive conditions by which a CIC would be triggered. In 2013, the Compensation Committee determined that the CIC conditions continue to be appropriate given our ownership structure. None of the CIC agreements provides for tax gross-ups under Sections 280G and 4999 of the Code. For more information regarding our NEO CIC agreements, please refer to “CIC Agreements” on page 50.

Stock Ownership Guidelines

The Compensation Committee instituted stock ownership guidelines for our NEOs in August 2010 in an effort to ensure that our NEOs have significant long-term value creation tied to stock price appreciation. Ownership requirements and progress toward their achievement are reviewed annually as part of the compensation planning process. A significant percentage of each NEO’s compensation is directly linked to our stock price appreciation.

The stock ownership guidelines for our NEOs are calculated as a fixed number of shares using a required ownership multiple, the executive’s annualized base salary as of a certain date, and the stock price as of a fixed date. The 2013 required ownership multiple for our CEO is six times annual base pay and is three times annual base pay for our other NEOs.

Shares may be counted toward the policy’s ownership guidelines whether held directly by the NEO or owned jointly with a partner, provided that shares are vested. For stock options, the value must exceed the exercise price (“in-the-money” options). We include vested, unexercised, but “in-the-money” stock options in the calculation.

Stock ownership guidelines must be met within five years from the date of adoption of the guidelines for

Messrs. Espe, Mangas and Ready since they were hired prior to the adoption of the guidelines, and within five years from date of hire or promotion into the role for Messrs. Schulz, Grizzle, Hershey, and Maier.

The Compensation Committee last reviewed the NEOs’ progress toward meeting the ownership requirements in February 2014. As of the date of the review, all NEOs except Messrs. Schulz, Hershey and Maier had met their ownership requirements. Mr. Schulz was promoted on November 16, 2013. Mr. Hershey was hired on July 1, 2011. Both NEOs are expected to meet ownership requirements within the requisite five-year period. Mr. Maier has begun to diversify out of our stock in anticipation of his separation from the Company effective February 28, 2015.

Recoupment Policy

In order to further align management’s interests with the interests of shareholders and support good governance practices, we expanded our recoupment policy applicable to short- and long-term incentive awards. In the event we are required to prepare an accounting restatement due to a material noncompliance with any financial reporting requirement under the securities laws as a result of fraud, misconduct, or gross negligence, we may exercise discretion and take action to recoup the amount of any awards, including cash or stock-based awards, which exceed the payment that would have been made based on the restated financial results. To the extent that in the future the SEC adopts rules for clawback policies that require changes to our policy, we will revise our policy accordingly.

Prohibition on Derivative Trading

All members of our Board and senior management, including our NEOs and certain other employees, are required to clear any transaction involving Company securities with our General Counsel prior to entering into such transaction.

Our company prohibits derivative transactions in our Company securities, including:

• Trading in puts, calls, covered calls, or other derivative products involving Company securities.

• Engaging in any hedging or monetization transaction with respect to Company securities.

34          2014 Proxy Statement

COMPENSATION DISCUSSION AND ANALYSIS(CONTINUED)

• Holding company securities in a margin account or pledging Company securities as collateral for a loan.

Beginning in 2011, we permitted senior management to utilize stock trading plans that comply with Rule 10b5-1 of the Exchange Act. All such plans are subject to our pre-approval, and the ability to enter into such plans remains subject to prohibitions on trading while in possession of material non-public information.

Assessment of Risk

We monitor the risks associated with our compensation program on an ongoing basis. At the conclusion of its most recent analysis of our compensation programs and associated risks, it was the assessment of the Compensation Committee, with the assistance of Towers Watson and management, that our compensation programs are designed and administered with an appropriate balance of risk and reward and, by their design, do not encourage executives to take unnecessary, excessive, or inappropriate risks and do not create risks that are reasonably likely to have a material adverse effect on the Company. In arriving at this determination, the Compensation Committee considered the following with respect to our compensation programs:

• Whether the underlying pay philosophy, Peer Group and market positioning to support business objectives were appropriate.

• Effective balance in:

• Cash and equity mix.

• Short- and long-term performance focus, with performance goals tied to profitability and absolute stock price performance.

• Use of multiple performance metrics in the annual and long-term incentive plans.

• Performance objectives are established using a reasonable probability of achievement.

• Long-term incentive plan is tied to operating performance over a multi-year performance period.

• The Compensation Committee’s ability to exercise discretion to reduce MAP amounts earned based on subjective evaluation of quality of earnings and individual performance.

• The presence of meaningful risk mitigation policies, such as stock ownership guidelines, claw-back provisions, and independent Compensation Committee oversight; and prohibitions on hedging against and pledging of our Common Shares.

Tax Deductibility of Compensation

The Internal Revenue Code imposes a $1 million limit on the amount that a public company may deduct for compensation paid to the company’s CEO or any of the company’s three other most highly compensated executive officers (other than the CFO) who are employed as of the end of the year.

This limitation does not apply to compensation that meets the tax code requirements for “qualifying performance-based” compensation (i.e., compensation paid only if the individual’s performance meets pre-established objective goals based on performance criteria approved by shareowners).

Generally, it is our policy to structure and administer our annual and long-term incentive compensation plans for the NEOs to maximize the tax deductibility of the payments as “performance-based compensation” under Section 162(m) of the Internal Revenue Code to the extent practicable. The Compensation Committee considers both tax and accounting treatment in establishing our compensation program. However, in certain circumstances, the Compensation Committee may authorize compensation arrangements that are not fully tax deductible, but which promote other important objectives, such as attracting and retaining global business leaders who can drive financial and strategic growth objectives that maximize long-term shareholder value.

In 2013, all incentive compensation for the NEOs, including MAP and LTIP, was designed to be exempt from the Section 162(m) deduction limit.

(1) Mr. Schulz was named Senior Vice President and Chief Financial Officer in November, 2013 when Mr. Mangas transitioned to Executive Vice President and CEO of Armstrong Floor Products.

(2) Mr. Ready served as the Executive Vice President and CEO of Armstrong Floor Products until November, 2013 and retired effective December 31, 2013.

(3) Mr. Ready received a cash retention payment of $500,000 on January 1, 2013. In January 2010, Mr. Ready received a cash retention agreement in the amount of $1.5 million. The first installment of $1 million was paid January 2012 and the final installment was paid in January 2013. The details of this arrangement were outlined in the 2011 Proxy.

(4) The amounts reflect the aggregate grant date fair value of stock and option awards granted in the fiscal year, computed in accordance with the Financial Accounting Standards Board’s Accounting Standards Codification Topic 718. The assumptions used to determine the valuation of our option awards are set forth on page 39. The potential maximum fair value of the performance restricted award at the grant date market price would be $2,205,000 for Mr. Espe, $90,790 for Mr. Schulz, $700,000 for both Messrs. Mangas and Ready, and $567,000 for Mr. Grizzle, $420,000 for Mr. Maier and $387,100 for Mr. Hershey.

(5) The 2013 amounts disclosed are the awards under the 2013 MAP. As specified under the MAP, award amounts are subject to a mandatory reduction of up to $20,000 to the extent a corresponding contribution can be made to the Bonus Replacement Retirement Plan, which is a qualified, tax-deferred profit sharing plan. For 2013, a $16,000 reduction was made for Messrs. Espe, Mangas and Grizzle, $15,000 for Mr. Schulz, $17,156 for Mr. Maier, $18,829 for Mr. Hershey and $20,000 for Mr. Ready.

2013 SUMMARY COMPENSATION TABLE(CONTINUED)

(6) Although Mr. Ready accrued additional benefits in 2013, the present value of his pension decreased by 312,267. The decrease was primarily due to changes in the actuarial assumptions used to calculate the present value of pension benefits. In accordance with the Securities and Exchange Commission guidelines, if the change in pension value is negative, it is not shown in the table above. This column is also intended to report above-market earnings on nonqualified deferred compensation balances – the only NEO to have above-market interest is Mr. Ready.

(7) The amounts shown in the “All Other Compensation” column include: (i) cash dividends paid; (ii) Company matching contribution to the Savings and Investment 401(k) Plan (and for Messrs. Hershey, Mangas, Maier and Schulz to the NQDCP); (iii) premiums for long-term disability insurance; (iv) relocation expenses, and (v) personal benefits (“perquisites”) consisting of medical examinations and financial planning expense reimbursements to the extent the total perquisite value is $10,000 or greater per individual. For each person the total value of all such perquisites did not reach $10,000. except for Mr. Espe. Mr. Espe’s perquisite value was $11,398 and, therefore, the amount is included in the “All Other Compensation” column.

(8) The following table provides the detail for the amounts reported in the All Other Compensation for 2013 for each NEO:

Mr. Ready			8,750	2,273		32,691		43,714

(a) Represents annual physical, personal financial planning, sporting tickets and travel for spouses to Board meetings.

Tickets to sporting and other entertainment events are sometimes provided, without charge, to certain employees, including the NEOs, to attend these events for business purposes. Tickets made available to employees, including the NEOs for personal use only if the tickets are not otherwise needed for business use. The Company does not incur incremental costs with respect to personal use of these tickets because the tickets were purchased by the Company for business purposes. Any amounts included are attributable to such events, therefore, reflect personal catering and related costs.

The spouses of Board members and NEOs are invited to attend the Board’s regularly scheduled February meeting. The incremental costs incurred by the Company for spouse travel and lodging are included.

(b) Cash dividends were paid upon vesting of RSU’s and PSU’s in 2013. Further details can be found in the Stock Vested table.

(c) Represents tax reimbursement in accordance to the Company Travel Policy, a tax assisted payment will be made to an employee who opts to downgrade from business to economy for flights that exceed 12 hours. Mr. Schulz received such a payment in 2013 prior to becoming CFO.

(d) Accrued and unpaid vacation pay, represents the value of vacation in accordance with Company policy.

(1) The amounts shown represent the 2013 MAP opportunity for each NEO. Actual payouts are included in the Non-Equity Incentive Plan Compensation column of the SCT.

(2) In 2013, our LTI program for NEOs consisted of 60% stock options and 40% PSU. The exercise price of the stock options was $51.76. The stock options vest and become exercisable in three equal installments on the first, second and third anniversaries of the effective date of the grant. PSUs have a three-year performance period based on ROIC; participants earn 100% of the performance restricted shares if the Company achieves 100% of the ROIC target. Any cash dividends declared will be accrued in a non-interest bearing account and paid when the restrictions on the underlying shares lapse.

(3) For purposes of determining the fair value of stock option awards, the Company uses the Black-Scholes option pricing model and the assumptions set forth in the table below. The grant date fair value of options granted in 2013 was $21.61.

PENSION BENEFITS

The table below shows the present value of accumulated benefits payable to each of the NEOs, including the number of years of service credited to each such NEO, under the RIP and the RBEP as of December 31, 2013. The amounts were determined using the same interest rate and mortality rate assumptions used in the Company’s Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2013. Information regarding the RIP and RBEP can be found in Note 19 to the Company’s Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2013.

	Retirement Benefit Equity Plan of Armstrong World Industries, Inc.		30.5		1,855,224		0

The RBEP was established to pay any benefit which cannot be paid under the RIP due to Code compensation or benefits limitations. All pension benefits are paid by the Company. The pension plans were closed to new salaried participants effective January 1, 2005. Benefits payable under the RIP and RBEP are based on a formula that yields an annual amount payable over the participant’s lifetime beginning at the age where the participant qualifies for an unreduced life annuity benefit.

In addition, Mr. Ready may qualify for an additional annuity payment under the ESOP Pension Account (the “EPA”) to the extent such benefit can be paid under the qualified pension plan. The EPA was established in 2000 to restore a portion of the value lost by a broad group of employees who had

purchased shares of Company stock and received Company contributions of additional shares which were intended to help fund the cost of their retiree health care coverage. The starting EPA balance was determined by multiplying the number of ESOP shares held by the participant by $47.75 which was the guaranteed value of the original ESOP

convertible preferred shares. The EPA is credited with interest annually using the November 30-year Treasury bond rate. Interest is credited up to the date the participant commences regular pension benefits under the RIP.

Participants in the RIP may retire as early as age 55 provided the participant is vested under the plan. Participants become vested after completing five years of continuous employment having worked at least 1,000 hours in each year. Normal retirement date is the first of the month nearest the participant’s 65^th birthday. Except as noted below, there is a reduction for early retirement for salaried participants who retire between the ages of 55 and 65. An employee who retires from active employment can receive an unreduced pension benefit commencing on the date of retirement if the employee’s age (minimum age 55) and Total Service totals 90 points (the “Rule of 90”). The unreduced Rule of 90 benefit is limited to the employee’s pension amount accrued to February 28, 2006. Employees receive credit for post-March 1, 2006 age and service for Rule of 90 eligibility.

     2014 Proxy Statement     43

PENSION BENEFITS(CONTINUED)

The normal form of benefit payment is a monthly annuity. Except for payments having a lump sum present value of $10,000 or less under the qualified plan, no lump sum payments are permitted. Various forms of annuity payments (including life, joint and survivor, period certain and level income options) are available under the pension plans. The annuity payments for these options are determined by actuarially adjusting the life annuity pension amount for the selected form of payment. The formula for the regular life annuity pension benefit for salaried employees under the RIP is based on the following factors:

• the participant’s Average Final Compensation (the “AFC”) which is the average of the three highest years of eligible compensation (base salary plus annual incentive) during the last ten years of employment;

• the participant’s number of years of Total Service (credited years of employment with the Company) used to calculate the pension amount; and

• the participant’s Adjusted Covered Compensation (the “ACC”), which is a percentage of the average Social Security tax base for the 35-year period ending with the year the participant will qualify for an unreduced Social Security pension benefit.

The unreduced annual life annuity pension is the sum of the following four calculations, each of which may not be less than zero:

1. AFC x 0.009 x Total Service to a maximum of 35 years; plus

2. (AFC – ACC) x 0.005 x Total Service to 35 years; plus

3. (AFC – 2 x ACC) x 0.0015 x Total Service to 35 years; plus

4. AFC x 0.012 x Total Service over 35 years.

To the extent the participant is eligible for an EPA pension benefit that can be paid from the RIP, all of the allowable portion of the calculated EPA annuity will be added to the regular pension amount. EPA annuity amounts that cannot be paid from the qualified plan are forfeited.

Special provisions apply if the qualified pension plan is terminated within five years following an Extraordinary Event, as this term is defined in the RIP. Upon the occurrence of such an event, plan liabilities would first be satisfied, and then remaining plan assets would be applied to increase retirement income to employees. The amount of the increase is based on the assumption that the employee would have continued employment with Armstrong until retirement. The NEOs who are eligible for RIP pension benefits would be entitled to this benefit under these circumstances.

The assumptions used to calculate the actuarial present values shown in the table above are as follows:

• Discount rate used to value benefit obligations equals 4.75%;

• IRS 2014 Static Projected 2021/2029;

• EPA interest rate of 2.80%;

• 1994 GAR (RR 2001-62) Mortality Table for EPA annuity conversion; and

• Retirement at age 65 or Rule of 90 eligibility, as specified.

Armstrong maintains two nonqualified deferred compensation plans that apply to certain of the NEOs. The Armstrong Deferred Compensation Plan, which was established in 1985, was closed to new deferrals of base salary and annual incentive compensation starting in 2001. The plan is partially funded with Company-owned life insurance policies held in a grantor trust. These policies were purchased by the Company prior to 1996. Mr. Ready is the only NEO participant in this plan. Participants may transfer account balances between any of the plan’s available investment options.

The normal form of payout is a 15-year annuity with monthly payments starting on a post-employment date selected by the participant (minimum age 55) but in no event commencing later than the participant’s 65^th birthday. Requests for single sum payments are subject to approval by the Company.

If a participant resigns or is discharged for willful, deliberate or gross misconduct, the participant may be paid a single sum amount equal to 94% of the

account balance (subject to Company approval) and would forfeit the remaining account balance. If a participant dies before commencing annuity payments, a survivor benefit will be paid to the participant’s designated beneficiary (or estate) as a ten-year annuity. The present value of the survivor benefit is the greater of the participant’s account balance or an amount equal to three times the participant’s actual deferrals. If the participant dies after commencing annuity payments, the remaining payments will be made to the participant’s designated beneficiary or estate.

As explained under the Pension Benefits section, the Company’s defined benefit pension plans were closed to new salaried participants effective January 1, 2005 and existing salaried participants who did not meet the age and service requirements as of March 1, 2006. The NEOs who fall into this category are eligible to participate in a 401(k) savings plan with an enhanced Company match. Armstrong matches 100% on the first 4% of employee contributions and 50% on the next 4% of employee contributions in the enhanced plan. The

     2014 Proxy Statement     45

NONQUALIFIED DEFERRED COMPENSATION(CONTINUED)

NQDCP was established to provide benefits similar to the 401(k) as it applies to eligible managers whose eligible earnings (base salary plus annual incentive) exceed 12.5 times the Code 402(g) elective deferral limit in effect for the plan year. For 2013, the eligible earnings limit was $218,750. A participant may elect to defer up to 8% of eligible base salary earnings and up to 8% of eligible annual incentive earnings. The Company matching contribution will be the same as that provided under the qualified 401(k) savings plan with the enhanced Company match. Messrs. Schulz, Mangas, Maier and Hershey are the only NEOs who participated in this unfunded, nonqualified plan. Participants may transfer account balances between any of the plan’s available investment options.

Participants become 100% vested in the Company match account after completing three years of continuous employment having worked at least 1,000 hours in each year.

Except in the case of an unforeseeable emergency or having reached age 70, no in-service distributions are permitted. Participants can elect to receive plan benefits as a single lump sum or in 120 monthly installments commencing after the date of the participant’s termination of employment. All elections must comply with the Code requirements. If the total account value is less than $10,000, the entire account balance will be paid as a single sum at the time of termination. In the event of a participant’s death, any remaining payments shall be paid to the participant’s designated beneficiary or estate.

The Company reserves the right to cause the participant to forfeit or require repayment of the Company match benefits where the participant is discharged for willful, deliberate or gross misconduct or where the participant has engaged in conduct that is injurious to the Company.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL

The tables below summarize the estimated value of the potential payments and benefits under the Company’s plans and arrangements to which the NEOs would be entitled upon termination of employment under the circumstances indicated. Except for the continuation of health and welfare benefits and outplacement support, amounts would be paid as a lump sum at termination. The amounts shown assume that such termination was effective December 31, 2013. There is no table for Mr. Ready whose CIC agreement terminated upon his retirement on December 31, 2013. The payments made to Mr. Ready upon his termination were disclosed in a Form 8-K filed with the SEC on December 2, 2013.

Each of the NEOs who participate in the Company’s pension benefits and / or nonqualified deferred compensation plans are eligible for the benefits shown in the tables above. The “Change in Control” column assumes no cap under the best net provision in each CIC agreement. In addition, amounts in the “Change in Control” column are applicable only following a CIC event and either an involuntary (without cause) termination or a Termination for Good Reason under the CIC agreement.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL(CONTINUED)

RESIGNATION OR INVOLUNTARY TERMINATION FOR CAUSE

No incremental benefits are provided to any of the NEOs in the event of a voluntary resignation or an involuntary termination for Cause. Cause is defined as (i) the willful and continued failure by the executive to substantially perform the executive’s duties after a written demand for substantial performance is delivered to the executive by the Board, or (ii) the willful engaging by the executive in conduct which is demonstrably and materially injurious to the Company, or (iii) the executive’s conviction of any felony.

Involuntary Termination without Cause

Severance benefits for executive participants provide a minimum of twenty-six weeks and a maximum of fifty-two weeks of base salary based on years of service, or a separate contractual arrangement. A Severance Pay Committee, composed of members of management, reserves the right to depart from the severance pay schedule where factors justify an upward or downward adjustment in the level of benefits. In no event may the severance payment exceed two times the participant’s annual compensation.

In the event of involuntary termination where severance applies, all salaried employees are eligible for continuation of health care and life insurance benefits at active employee premium contributions for a period of six months unless the employee is eligible for and elects retiree health care coverage. In addition, senior executives are eligible for twelve months of executive outplacement support provided by an outside service provider.

Pursuant to Mr. Espe’s employment agreement, he will be entitled to the following severance pay and

benefits, conditioned on the execution of a release and his compliance with certain restrictive covenants: (1) payment of 200% of his base salary, (2) welfare benefit continuation for 24 months and (3) a pro rata MAP payment. Mr. Espe will be subject to a two-year non-competition and non-solicitation agreement following his termination of employment. Please refer to the 2011 Proxy Statement for a summary of Mr. Espe’s employment agreement.

The offer letters for Messrs. Mangas and Grizzle state that health care and life insurance benefits would continue at the active employee contribution levels for twelve months.

Termination for Good Reason

Termination for Good Reason is defined in each executive’s individual CIC agreement and includes any one of the following events (following a CIC):

(i) the assignment to the executive of any duties inconsistent with the executive’s status as an executive officer of the Company or a substantial adverse alteration in the nature or status of the executive’s responsibilities;

(ii) a reduction by the Company in the executive’s annual base salary;

(iii) failure by the Company to pay to the executive any portion of the executive’s current compensation; or

(iv) failure by the Company to continue in effect any compensation or benefit plan in which the executive participates immediately prior to a CIC which is material to the executive’s total compensation unless an equitable arrangement has been made.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL(CONTINUED)

CIC Agreements

We do not provide tax gross-ups under Sections 280G and 4999 of the Code to any of our NEOs. Set forth below are certain key terms of the CIC agreements:

Term of Agreement	Fixed one-year term that automatically renews for an additional year unless notice is given at least 90 days prior to the anniversary of intent not to renew; term automatically continues for two years if the CIC occurs during term
Severance Benefits	2.5 times base salary plus target MAP for Mr. Espe, two times base salary plus target MAP for Messrs. Schulz, Mangas, Grizzle, Maier, and Hershey
Pro rata MAP	Based on actual results achieved under MAP year during which the termination occurs if a change in control termination occurs prior to the completion of the applicable performance period
Accelerated Equity Vesting	Double-trigger accelerated vesting (requires a CIC and termination of employment) for stock options and RSU to vest if assumed by the acquirer; cash-out equity if not assumed by the acquirer
280G Taxation	Any amounts paid under the CIC Agreement will be reduced to the maximum amount that can be paid without being subject to the excise tax imposed under Internal Revenue Code Section 280G, but only if the after-tax benefit of the reduced amount is higher than the after-tax benefit of the unreduced amount

In addition, the CIC agreements contain a definition of CIC that the Compensation Committee has determined to be appropriate given our current ownership structure.

52          2014 Proxy Statement

ITEM 3 – ADVISORY APPROVAL OF EXECUTIVE COMPENSATION

Our shareholders voted in 2011, in a non-binding vote, in favor of the submission of the Company’s compensation of its NEOs triennially to our shareholders on a non-binding basis, and our Board has adopted that approach. In accordance with the outcome of that shareholder vote and regulations under Section 14A of the Exchange Act, we are including in this proxy statement a separate resolution, subject to a non-binding shareholder vote, to approve the compensation of our NEOs as disclosed in certain sections of this proxy statement. This non-binding vote is commonly known as a “say-on-pay” proposal, which gives our shareholders the opportunity to endorse our NEO pay program and policies.

In considering their vote, we encourage shareholders to carefully review our compensation policies and decisions regarding our NEOs as presented in the “Compensation Discussion and Analysis” on pages 22 to 35 and the related compensation tables beginning on page 37.

Our Compensation Committee has developed and maintained a compensation program that is intended to: align executive interests with

shareholders’ interests; link pay and performance by placing a significant portion of compensation “at risk” based on performance against pre-established goals; and provide a competitive level of compensation globally to enable access to high-quality executives in a highly competitive market.

Accordingly, we are asking our shareholders to approve, in a non-binding vote, the following resolution:

“RESOLVED, that the shareholders approve, in a non-binding vote, the compensation paid to the Company’s named executive officers as disclosed in the Company’s Proxy Statement for the 2014 Annual Meeting of Shareholders pursuant to Item 402 of Regulation S-K, including the “Compensation Discussion and Analysis” beginning on page 22 of the proxy statement and the related compensation tables and narrative discussion.”

The next advisory vote to approve our executive compensation will occur at the 2017 Annual Meeting of Shareholders, unless our Board modifies its policy on the frequency of holding such advisory votes.

     2014 Proxy Statement     53

ADDITIONAL MEETING INFORMATION

Why did I receive a one-page notice in the mail regarding the Internet availability of proxy materials instead of a full set of proxy materials?

This year we have again utilized the SEC rule allowing companies to furnish proxy materials to their shareholders over the Internet. We believe that this approach enables us to provide the materials to shareholders more quickly, while also reducing the impact of our annual meeting on the environment and the costs associated with printing and mailing.

How can I receive printed shareholder and proxy materials?

Please follow the instructions for “How to Access the Proxy Materials” on the one-page notice described above.

Who is soliciting my proxy?

The Board is soliciting your proxy in order to provide you with an opportunity to vote on all matters scheduled to come before the meeting, whether or not you attend the meeting in person.

Who is entitled to vote?

Each holder of record of our Common Shares, at the close of business on the record date, April 7, 2014 (“Record Date”), is entitled to one vote for each Common Share owned on each matter to be voted on. As of the Record Date, 54,807,961 Common Shares were issued and outstanding and entitled to vote at the annual meeting.

What must I do to attend the meeting via the Internet?

You may attend and participate in the annual meeting via the Internet atwww.virtualshareholdermeeting.com/awi2014where you will be able to vote and submit questions during the meeting. Shareholders who use the control number that was furnished to them (either with the notice sent to them regarding the availability of these proxy materials or with their copy of these proxy materials) to log on to the meeting will be able to vote and submit questions during the meeting.

What must I do to attend the meeting in person?

If you wish to attend the meeting in person, you must have been a shareholder on the Record Date and you must present an admission ticket and photo identification. To request an admission ticket and get directions, please email or write the Office of the Corporate Secretary atAdmissionTicket@armstrong.com or Attention: C. L. Putt, Armstrong World Industries, Inc., P. O. Box 3001, Lancaster, PA 17604-3001. We must receive your request at least ten business days prior to the meeting. If your Common Shares are held directly in an account with our transfer agent, AST, your name will appear in our Record Date shareholder list. If your Common Shares are in the name of a broker, bank or other institution, you must provide evidence of your beneficial stock ownership on the Record Date.

How can I revoke my proxy?

Proxies are voted at the annual meeting. You may revoke your proxy at any time before it is voted, and your last vote is the vote that will be counted. If you are a shareholder of record on the Record Date and you returned a paper proxy card, you can write to the Company’s Secretary at our corporate offices, 2500 Columbia Avenue Lancaster, Pennsylvania 17603, stating that you wish to revoke your proxy and that you need another proxy card. If you submitted your proxy by the Internet or by telephone, you can vote again over the Internet or by telephone. If you hold your Common Shares through a broker, bank or other nominee, you can revoke your proxy by contacting the broker, bank or other nominee and following its procedure for revocation. If you are a shareholder of record on the Record Date and you attend the annual meeting, you must request a revocation of your submitted proxy and vote by ballot to revoke your proxy. Your appearance alone at the annual meeting will not of itself constitute a revocation of your proxy.

How many votes can be cast by all shareholders?

54,807,961 votes, consisting of one vote for each outstanding Common Share outstanding on the Record Date.

54          2014 Proxy Statement

ADDITIONAL MEETING INFORMATION(CONTINUED)

What is the quorum requirement for the Annual Meeting?

A quorum of the holders of the outstanding Common Shares must be present for the annual meeting to be held. A “quorum” is the presence at the annual meeting, in person or represented by proxy, of shareholders entitled to cast at least a majority of the votes which all shareholders are entitled to cast on each matter to be acted on at the annual meeting. Abstentions and broker “non-votes” are counted as present and entitled to vote for purposes of determining a quorum. A broker “non-vote” occurs when a broker does not vote on a particular proposal because the broker does not have discretionary voting power with respect to the proposal and has not received voting instructions from the beneficial owner.

What if a quorum is not present at the Annual Meeting?

If the annual meeting cannot be organized because a quorum is not present, the shareholders present at the annual meeting will have the power, except as otherwise provided by statute, to adjourn the annual meeting to such time and place as they may determine. Those shareholders who attend or participate at such adjourned meeting, even if less than a quorum, shall nevertheless constitute a quorum for the purpose of electing directors.

What vote is required to approve each item?

The director nominees 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. The ratification of the appointment of KPMG LLP as our independent registered public accounting firm for 2014 and the advisory approval of our executive compensation require the affirmative vote of a majority of the votes present and entitled to vote at the meeting to be approved. Any other matters that may be acted upon at the annual meeting will be determined by the affirmative vote of the holders of a majority of our Common Shares represented in person, via the Internet, or by proxy at the annual meeting and entitled to vote on the matter.

How are votes, abstentions and broker non-votes counted?

Broker non-votes will be included in determining whether a quorum is present but will have no effect

on the outcome of the matters to be voted upon at the annual meeting, including in connection with the election of directors. Abstentions are not considered a vote cast under Pennsylvania law. Under our Bylaws, however, other than in connection with the election of directors, abstentions will have the effect of a negative vote with respect to matters to be voted upon at the Annual Meeting.

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 and any votes cast in person for a fee of approximately $15,000 plus reasonable expenses.

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

It means that you have multiple accounts in which you own our Common Shares. Please vote all proxy cards/voting instructions from the Company to ensure that all your Common Shares are voted. However, you may want to contact your broker, bank or the Company’s 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 them at American Stock Transfer & Trust Company, LLC, 6201 15^th Avenue Brooklyn, NY 11219; or by email to info@amstock.com; or by phone (1-800-937-5449).

What should we do if multiple shareholders reside in our household, and we wish to change the 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 shareholders in your household. If you would prefer to receive separate copies of a proxy statement or annual report for other shareholders in your household, either now or in the future, please contact youjr bank, broker, broker-dealer or other similar organization serving as your nominee. Upon written or oral request to

     2014 Proxy Statement     55

ADDITIONAL MEETING INFORMATION(CONTINUED)

the attention of Investor Relations, 2500 Columbia Avenue Lancaster, Pennsylvania 17603, or via telephone to the Investor Relations department at 717-396-6354, we will promptly provide separate copies of the annual report and/or this proxy statement. Shareholders sharing an address who are receiving multiple copies of 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 shareholders at the shared address in the future.

Who may solicit proxies on the Company’s behalf?

Our directors, officers and employees may solicit proxies from our shareholders. These persons will not receive any additional compensation for these services. We will request that the Notice of Annual Meeting, this proxy statement, the proxy card, and related materials (if any), be forwarded to beneficial owners by banks, brokers and other persons for their reasonable out-of-pocket expenses in handling these materials. We will bear the costs of and expect to reimburse them for all such solicitations. We have also engaged Innisfree M&A Incorporated to solicit proxies for an estimated fee of approximately $15,000, plus expenses.

OTHER BUSINESS

The Board knows of no matters other than the foregoing to come before the meeting. However, if any other matters come before the meeting, the persons named in the enclosed proxy will vote in their discretion with respect to such other matters.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Exchange Act and the regulations thereunder require certain of our officers, as well as our directors and persons who own more than 10% of a registered class of our equity securities (collectively, the “reporting persons”) to file reports of ownership and changes in ownership with the SEC and to furnish us with copies of these reports. Based solely on our review

of the copies of these reports within a prescribed period of time and written representations we received from the reporting persons, we believe that all filings required to be made by the reporting persons during or with respect to the period January 1, 2013 through December 31, 2013 were made on a timely basis.

SUBMISSION OF SHAREHOLDER PROPOSALS

In order to submit shareholder proposals for the 2015 Annual Meeting of Shareholders for inclusion in the Company’s 2015 proxy statement pursuant to SEC Rule 14a-8, materials must be received by the Corporate Secretary at the Company’s corporate

offices in Lancaster, Pennsylvania, no later than December 24, 2014.

The proposals must comply with all of the requirements of SEC Rule 14a-8. Proposals should

56          2014 Proxy Statement

SUBMISSION OF SHAREHOLDER PROPOSALS(CONTINUED)

be addressed to: Corporate Secretary, 2500 Columbia Avenue, Lancaster, Pennsylvania 17603. As the rules of the SEC make clear, simply submitting a proposal does not guarantee its inclusion.

The Bylaws also establish an advance notice procedure with regard to director nominations and shareholder proposals that are not submitted for inclusion in the proxy statement, but that a shareholder instead wishes to present directly at an annual meeting. To be properly brought before the 2015 Annual Meeting of Shareholders, a notice of the nomination or the matter the shareholder wishes to present at the meeting must be delivered to the Corporate Secretary at the Company’s corporate offices in Lancaster (see above), not less than 90 days prior to the first anniversary of the date of this Annual Meeting. As a result, any notice given by or on behalf of a shareholder pursuant to these provisions of the Bylaws (and not pursuant to SEC Rule 14a-8) must be received no later than

March 22, 2015. All director nominations and shareholder proposals must comply with the requirements of our Bylaws, a copy of which may be obtained at no cost from the Corporate Secretary.

In either case, if the date of our 2015 Annual Meeting of Shareholders is more than 30 calendar days before or after the first anniversary of this annual meeting, your proposal must be received by the Corporate Secretary by close of business on the fifteenth day following the day we publicly announce the date of the 2015 Annual Meeting of Shareholders.

Any shareholder proposals not received by such applicable dates will be considered untimely and, if presented at the 2015 Annual Meeting of Shareholders, the proxy holders will be able to exercise discretionary authority to vote on any such proposal to the extent authorized by SECRule 14a-4(c).

ANNUAL REPORT ON FORM 10-K

Our Annual Report to Shareholders, including financial statements, is being furnished simultaneously with this proxy statement to all shareholders of record as of the Record Date. A copy of our Annual Report and Form 10-K for the year ended December 31, 2013, including financial statements, but excluding the financial statement schedules and most exhibits, will be provided without charge to shareholders upon written request to: Armstrong World Industries, Inc., Investor Relations, P.O. Box 3001, Lancaster, PA 17604.

Our Annual Report is also available at www.proxyvote.com, or www.armstrong.com – Company Information – Investor Relations – SEC Filings – 10-K. The Form 10-K will include a list of exhibits to the Form 10-K. Copies of exhibits will be furnished to shareholders upon written request and upon our receipt of payment of reproduction and mailing expenses.

INCORPORATION BY REFERENCE

To the extent that this proxy statement has been or will be specifically incorporated by reference into any other filing of Armstrong under the Securities Act of 1933 or the Exchange Act, the sections of this proxy statement entitled “Report of the Audit Committee” (to the extent permitted by the rules of the SEC) and “Compensation Committee Report” shall not be deemed to be so incorporated, unless specifically provided otherwise in such filing.

ANNEX A to Armstrong World Industries, Inc. 2014 Proxy Statement

To supplement its consolidated financial statements presented in accordance with accounting principles generally accepted in the United States (GAAP), the Company provides additional measures of performance adjusted to exclude the impact of foreign exchange, restructuring charges and related costs, impairments, and certain other gains and losses. Adjusted figures are reported in comparable dollars using the budgeted exchange rate for 2013. The Company uses these adjusted performance measures in managing the business, including communications with its Board of Directors and employees, and believes that they provide users of this financial information with meaningful comparisons of operating performance between current results and results in prior periods. The Company believes that these non-GAAP financial measures are appropriate to enhance understanding of its past performance, as well as prospects for its future performance. A reconciliation of these adjustments to the most directly comparable GAAP measures is included in this release and on the Company’s website. These non-GAAP measures should not be considered in isolation or as a substitute for the most comparable GAAP measures. Non-GAAP financial measures utilized by the Company may not be comparable to non-GAAP financial measures used by other companies.
