Cautionary Note Regarding Forward-Looking Statements

Certain information included in this report and in our other materials we have filed or will file with the Securities and Exchange Commission (“SEC”), as well as information included in oral statements or other written statements made or to be made by us, contains or may contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1955 (the “PSLRA”). Those statements provide our future expectations or forecasts and can be identified by our use of words such as “anticipate,” “estimate,” “expect,” “project,” “intend,” “plan,” “believe,” “outlook,” and other words or phrases of similar meaning in connection with any discussion of future operating or financial performance or the outcome of contingencies such as liabilities or legal proceedings.

Forward-looking statements, by their nature, address matters that are uncertain and involve risks (such as those referenced in Part II, Item 1A, Risk Factors of this report) because they relate to events and depend on circumstances that may or may not occur in the future. The risks and uncertainties identified in the forward looking statements contained in this report, together with those previously disclosed in our SEC filings, or those that are presently unforeseen, could result in significant adverse effects on our financial condition, results of operations and cash flows, and cause our actual results to differ materially from our expectations and from those expressed in our forward-looking statements.

We try to reduce the likelihood that these and other risks will significantly affect our businesses, as well as their potential impact. However, no matter how accurate our foresight, how well we evaluate risks, and how effective we are at mitigating them, one or more of these risks could have serious consequences for us, and could cause a material adverse effect on our business. See the related discussions in this document and our other SEC filings and other public documents for more details relating to the risks and uncertainties impacting our businesses. Forward-looking statements speak only as of the date they are made. We undertake no obligation to update any forward-looking statements beyond what is required under applicable securities law.

This discussion is provided as permitted by the PSLRA, and all of our forward-looking statements are expressly qualified in their entirety by the cautionary statements contained or referenced in this section.

NOTE 1. BUSINESS AND BASIS OF PRESENTATION

Armstrong World Industries, Inc. (“AWI”) is a Pennsylvania corporation incorporated in 1891. When we refer to “we”, “our” and “us” in these notes, we are referring to AWI and its subsidiaries. We use the term “AWI” when we are referring solely to Armstrong World Industries, Inc.

In December 2000, AWI filed a voluntary petition for relief (the “Filing”) under Chapter 11 of the U.S. Bankruptcy Code (the “Bankruptcy Code”) in the United States Bankruptcy Court for the District of Delaware (the “Bankruptcy Court”) in order to use the court-supervised reorganization process to achieve a resolution of AWI’s asbestos-related liability. On October 2, 2006, AWI’s court-approved plan of reorganization (“POR”) became effective and AWI emerged from Chapter 11. All claims in AWI’s Chapter 11 case have been resolved and closed.

On October 2, 2006, the Armstrong World Industries, Inc. Asbestos Personal Injury Settlement Trust (“Asbestos PI Trust”) was created to address AWI’s personal injury (including wrongful death) asbestos-related liability. All present and future asbestos-related personal injury claims against AWI, including contribution claims of co-defendants but excluding certain foreign claims against subsidiaries, arising directly or indirectly out of AWI’s pre-Filing use of, or other activities involving, asbestos are channeled to the Asbestos PI Trust.

In August 2009, Armor TPG Holdings LLC (“TPG”) and the Asbestos PI Trust entered into agreements whereby TPG purchased 7,000,000 shares of AWI common stock from the Asbestos PI Trust and acquired an economic interest in an additional 1,039,777 shares from the Asbestos PI Trust. The Asbestos PI Trust and TPG together hold more than 60% of AWI’s outstanding shares and have entered into a shareholders’ agreement, pursuant to which the Asbestos PI Trust and TPG have agreed to vote their shares together on certain matters.

The accounting policies used in preparing the Condensed Consolidated Financial Statements in this Form 10-Q are the same as those used in preparing the Consolidated Financial Statements for the year ended December 31, 2011. These statements should therefore be read in conjunction with the Consolidated Financial Statements and notes that are included in the Form 10-K for the fiscal year ended December 31, 2011. In the opinion of management, all adjustments of a normal recurring nature have been included to provide a fair statement of the results for the reporting periods presented. Quarterly results are not necessarily indicative of annual earnings, primarily due to the different level of sales in each quarter of the year and the possibility of changes in general economic conditions.

Certain amounts in the prior year’s Condensed Consolidated Financial Statements have been recast to conform to the 2012 presentation.

These Condensed Consolidated Financial Statements are prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). The statements include management estimates and judgments, where appropriate. Management utilizes estimates to record many items including certain asset values, allowances for bad debts, inventory obsolescence and lower of cost or market charges, warranty, workers’ compensation, general liability and environmental claims and income taxes. When preparing an estimate, management determines the amount based upon the consideration of relevant information. Management may confer with outside parties, including outside counsel. Actual results may differ from these estimates.

Operating results for the first quarters of 2012 and 2011 included in this report are unaudited. However, these Condensed Consolidated Financial Statements have been reviewed by an independent registered public accounting firm in accordance with standards of the Public Company Accounting Oversight Board (United States) for a limited review of interim financial information.

In June 2011, the FASB issued new guidance that is now part of ASC 220: “Presentation of Comprehensive Income”. The new guidance requires companies to present the components of net income and other comprehensive income either as one continuous statement or as two consecutive statements. It eliminates the option to present components of other comprehensive income as part of the statement of changes in stockholder’s equity. The standard does not change the items which must be reported in other comprehensive income. These provisions are to be applied retrospectively and were effective for us as of January 1, 2012. There was no impact on our financial condition, results of operations or cash flows.

Notes to Condensed Consolidated Financial Statements (Unaudited)

(dollar amounts in millions)

Impairment testing of our tangible assets occurs whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. In March 2012, we made the decision to permanently close a previously idled ceiling tile plant in Mobile, Alabama. As a result, we recorded accelerated depreciation of $9.3 million for machinery and equipment and a $4.6 million impairment charge for buildings in cost of goods sold. The preliminary fair values were determined by management estimates and an independent valuation based on information available at that time (considered Level 2 inputs in the fair value hierarchy). Future charges may be incurred as more data becomes available.

During the first quarter of 2011, we announced the idling of our Statesville, NC engineered wood production facility. As a result, we evaluated the impairment implications of this decision and determined no impairment charge was necessary.

NOTE 8. SEVERANCES AND RELATED COSTS

See Note 9 to the Condensed Consolidated Financial Statements for a discussion of severance charges associated with restructuring actions.

In the first quarter of 2011, we recorded $3.0 million in cost of goods sold for severance and related costs to reflect position eliminations in our European Resilient Flooring business as a result of improved manufacturing productivity. In addition, we recorded $0.5 million in SG&A expense for severance and related costs to reflect the separation costs for our former Senior Vice President, General Counsel and Secretary.

NOTE 9. RESTRUCTURING ACTIONS

During the third quarter of 2010, management made several significant decisions to address our cost structure. Given the materiality to our financial statements and impact to our operations, we decided to classify charges related to these actions as restructuring charges. The following table summarizes the restructuring charges recorded in the first quarters of 2012 and 2011:

	Three Months Ended March  31,
Action Title	2012		2011			Segment
Floor Products Europe	$	0.2	$	3.1		Resilient Flooring
North America SG&A		—		0.4		Unallocated Corporate, Resilient Flooring
Beaver Falls plant		—		1.6		Building Products
Other initiatives		—		(0.2	)	Wood Flooring
Total	$	0.2	$	4.9

Floor Products Europe: In the third quarter of 2010, we announced our intent to focus our European flooring strategy on products and regions in which we believe we can be a market leader, and to streamline our product range and sales organization accordingly. During the fourth quarter of 2010, we withdrew from the residential market and, as a result, we sold our Teesside, UK manufacturing facility. In addition, during the second quarter of 2011, we ceased production at our heterogeneous vinyl flooring plant in Holmsund, Sweden.

In addition to the restructuring costs reflected in the above table, in the first quarter of 2011, we recorded $2.1 million of other related costs in cost of goods sold ($1.7 million) and SG&A expense ($0.4 million). Other related costs are primarily related to inventory obsolescence, accelerated depreciation and plant closure costs.

Through March 31, 2012, we have incurred expense of $30.1 million related to this initiative. We do not expect to incur further material restructuring costs related to this initiative.

North America SG&A: We are committed to augmenting margin expansion through the aggressive adoption of projects to standardize, simplify or eliminate SG&A activities. As a result, in the third quarter of 2010, we began to restructure our North American SG&A operations. The first quarter 2011 restructuring expense related to this initiative was recorded in the Unallocated Corporate ($0.3 million) and Resilient Flooring ($0.1 million) segments.

Through March 31, 2012, we have incurred restructuring expense of $7.2 million related to this initiative. In total, we expect to incur restructuring expenses of up to $8 million related to this initiative through 2012 as we further streamline North American SG&A functions.

Beaver Falls Plant: Production at the Beaver Falls, Pennsylvania facility ended March 31, 2011, and production requirements have been transitioned to other facilities. The decision to close the plant was driven by the location and layout of the plant, technology limitations and the continued limited demand for the products we made at the plant.

In addition to the restructuring costs reflected in the table above, we also recorded $4.7 million of accelerated depreciation in the first quarter of 2011 in cost of goods sold.

(dollar amounts in millions)

Through March 31, 2012, we have incurred expense of $25.1 million related to this initiative. We do not expect to incur additional costs in the future as the plant was sold in 2011. The sale resulted in a net gain of $0.7 million which was recorded in SG&A in the third quarter of 2011.

The following table summarizes activity in the restructuring accruals.

Most of the accrual balance as of March 31, 2012 is expected to be paid by June 30, 2012.

NOTE 10. INCOME TAX EXPENSE

The effective tax rate for the first quarter 2012 was 41.7% which was lower than the 64.1% effective tax rate in the comparable period in 2011, primarily due to the favorable tax impact from our mix of income from international operations. Additionally, the effective tax rate was higher in the first quarter of 2011 since we increased state valuation allowances based on our projected ability to utilize the deferred tax assets to offset future taxable income.

We do not expect to record any material changes during 2012 to unrecognized tax benefits that were claimed on tax returns covering tax years ending on or before December 31, 2011.

NOTE 11. DEBT

On March 22, 2012, we amended our $1.05 billion senior credit facility arranged by Merrill Lynch, Pierce, Fenner & Smith, Inc., J.P. Morgan Securities, Inc. and Barclays Capital. We added $250 million to our existing Term Loan B facility. The amended $1.3 billion facility is made up of a $250 million revolving credit facility (with a $150 million sublimit for letters of credit), a $250 million Term Loan A and an $800 million Term Loan B. The facility is secured by U.S. personal property, the capital stock of material U.S. subsidiaries, and a pledge of 65% of the stock of our material first tier foreign subsidiaries. The only significant change to existing terms, conditions and covenants related to the consolidated leverage ratio covenant. Under the revised covenant, threshold ratios are as follow: 4.5 to1.0 through December 31, 2013, 4.0 to 1.0 through March 31, 2015, and 3.75 to 1.0 thereafter. During the first quarter of 2012, we were in compliance with all covenants of the previous and amended credit agreements.

In connection with the additional $250 million Term Loan B borrowings, we paid $7.6 million for bank, legal and other fees. This amount was capitalized and is being amortized into interest expense over the life of the loan.

Interest cost on projected benefit obligation		22.7			23.0
Expected return on plan assets		(35.0	)		(38.1	)
Amortization of prior service cost		0.5			0.5
Amortization of net actuarial loss		5.8			4.8
Net periodic pension (credit)	$	(2.1	)	$	(5.9	)
Retiree health and life insurance benefits

Interest cost on projected benefit obligation		2.4			3.6
Amortization of prior service cost		(0.1	)		—
Amortization of net actuarial gain		(3.0	)		(0.7	)
Net periodic postretirement benefit (credit) cost	$	(0.4	)	$	3.5
Non-U.S. defined-benefit pension plans
Service cost of benefits earned during the period	$	0.5		$	0.8
Interest cost on projected benefit obligation		3.9			4.4
Expected return on plan assets		(2.5	)		(3.3	)
Amortization of net actuarial loss		0.3			0.1
Net periodic pension cost	$	2.2		$	2.0

We currently estimate that the 2012 net periodic postretirement benefit cost for our U.S. retiree health and life insurance plans will total approximately $5 million.

NOTE 13. FINANCIAL INSTRUMENTS

We do not hold or issue financial instruments for trading purposes. The estimated fair values of our financial instruments are as follows:

	March 31, 2012						December 31, 2011
	Carrying amount			Estimated fair value			Carrying amount			Estimated fair value
Assets/(Liabilities), net:
Total debt, including current portion	$	(1,092.1	)	$	(1,092.1	)	$	(843.0	)	$	(835.2	)
Foreign currency contract obligations		(1.0	)		(1.0	)		1.1			1.1
Natural gas contracts		(10.2	)		(10.2	)		(9.3	)		(9.3	)
Interest rate swap contracts		(15.5	)		(15.5	)		(14.0	)		(14.0	)

The carrying amounts of cash and cash equivalents of $683.3 million at March 31, 2012 (made up of bank deposits), receivables, accounts payable and accrued expenses, short-term debt and current installments of long-term debt approximate fair value because of the short-term maturity of these instruments. The fair value estimates of long-term debt were based upon quotes from a major financial institution of recently observed trading levels of our Term Loan B debt. The fair value estimates of foreign currency contract obligations are estimated from market quotes provided by a well recognized national market data provider. The fair value estimates of natural gas contracts are estimated using internal valuation models with verification by obtaining quotes from major financial institutions. For natural gas swap transactions, fair value is calculated using NYMEX market quotes provided by a well recognized national market data provider. For natural gas option based strategies, fair value is calculated using an industry standard Black-Scholes model with market based inputs, including but not limited to, underlying asset price, strike price, implied volatility, discounted risk free rate and time to expiration, provided by a well recognized national market data provider. The fair value estimates for interest rate swap contracts are estimated by obtaining quotes from major financial institutions with verification by internal valuation models.

(dollar amounts in millions)

As of March 31, 2012 and December 31, 2011, we also had $0.2 million and $1.5 million, respectively, of restricted cash that is held by a trustee related to the construction of our Millwood, West Virginia mineral wool plant. The trustee has invested the cash in money market investments. The carrying value on our balance sheet approximates the fair value because of the short-term maturity of the instruments. We anticipate the release of these funds during the second quarter of 2012.

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. U.S. GAAP establishes a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. The three levels of inputs used to measure fair value are as follows:

Level 1 — Quoted prices in active markets for identical assets or liabilities.

Level 2 — Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.

Assets and liabilities are summarized below:

	March 31, 2012						December 31, 2011
	Fair value based on						Fair value based on
	Quoted, active markets Level 1			Other observable inputs Level 2			Quoted, active markets Level 1			Other observable inputs Level 2
Assets/(Liabilities), net:
Total debt, including current portion	$	(794.5	)	$	(297.6	)	$	(545.9	)	$	(289.3	)
Foreign currency contract obligations		(1.0	)		—			1.1			—
Natural gas contracts		—			(10.2	)		—			(9.3	)
Interest rate swap contracts		—			(15.5	)		—			(14.0	)

We do not have any financial assets or liabilities that are valued using Level 3 (unobservable) inputs.

NOTE 14. DERIVATIVE FINANCIAL INSTRUMENTS

We are exposed to market risk from changes in foreign exchange rates, interest rates and commodity prices that could impact our results of operations and financial condition. We use forward swaps and option contracts to hedge certain of these exposures. Exposure to individual counterparties is controlled and derivative financial instruments are entered into with a diversified group of major financial institutions. Forward swaps and option contracts are entered into for periods consistent with underlying exposure and do not constitute positions independent of those exposures. At inception, hedges that we designate as hedging instruments are formally documented as either (1) a hedge of a forecasted transaction or “cash flow” hedge, or (2) a hedge of the fair value of a recognized liability or asset or “fair value” hedge. We also formally assess both at inception and at least quarterly thereafter, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in either the fair value or cash flows of the hedged item. If it is determined that a derivative ceases to be a highly effective hedge, or if the anticipated transaction is no longer probable of occurring, we discontinue hedge accounting, and any future mark to market adjustments are recognized in earnings. We use derivative financial instruments as risk management tools and not for speculative trading purposes.

(dollar amounts in millions)

Counterparty Risk

We only enter into derivative transactions with established counterparties having a credit rating of BBB or better. We monitor counterparty credit default swap levels and credit ratings on a regular basis. All of our derivative transactions with counterparties are governed by master International Swap and Derivatives Association agreements (“ISDAs”) with netting arrangements. These agreements can limit our exposure in situations where we have gain and loss positions outstanding with a single counterparty. We generally do not post nor do we receive cash collateral with any counterparty for our derivative transactions. As of March 31, 2012, we had no cash collateral posted or received for any of our derivative transactions. These ISDAs do not have any credit contingent features; however, a default under our bank credit facility would trigger a default under these agreements. Exposure to individual counterparties is controlled, and thus we consider the risk of counterparty default to be negligible.

Commodity Price Risk

We purchase natural gas for use in the manufacture of ceiling tiles and other products, and to heat many of our facilities. As a result, we are exposed to fluctuations in the price of natural gas. We have a policy to reduce cost volatility for North American natural gas purchases by purchasing natural gas forward contracts and swaps, purchased call options, and zero-cost collars up to 24 months forward to reduce our overall exposure to natural gas price movements. There is a high correlation between the hedged item and the hedged instrument. The gains and losses on these transactions offset gains and losses on the transactions being hedged. These instruments are designated as cash flow hedges. At March 31, 2012 and December 31, 2011, the notional amount of these hedges was $41.2 million and $47.2 million, respectively. The mark-to-market gain or loss on qualifying hedges is included in other comprehensive income to the extent effective, and reclassified into cost of goods sold in the period during which the underlying gas is consumed. The mark-to-market gains or losses on ineffective portions of hedges are recognized in cost of goods sold immediately. The earnings impact of the ineffective portion of these hedges was not material for the first quarter of 2012 and 2011. The contracts are based on forecasted usage of natural gas measured in mmBtu’s.

Currency Rate Risk — Sales and Purchases

We manufacture and sell our products in a number of countries throughout the world and, as a result, we are exposed to movements in foreign currency exchange rates. To a large extent, our global manufacturing and sales provide a natural hedge of foreign currency exchange rate movement, as foreign currency expenses generally offset foreign currency revenues. We manage our cash flow exposures on a net basis and use derivatives to hedge the majority of our unmatched foreign currency cash inflows and outflows. As of March 31, 2012, our major foreign currency exposures are to the Canadian dollar, the Euro, and the Australian dollar.

We use foreign currency forward exchange contracts to reduce our exposure to the risk that the eventual net cash inflows and outflows resulting from the sale of products to foreign customers and purchases from foreign suppliers will be adversely affected by changes in exchange rates. These derivative instruments are used for forecasted transactions and are classified as cash flow hedges. Cash flow hedges are executed quarterly, generally up to 15 months forward, and allow us to further reduce our overall exposure to exchange rate movements, since gains and losses on these contracts offset gains and losses on the transactions being hedged. The notional amount of these hedges was $145.0 million and $128.3 million at March 31, 2012 and December 31, 2011, respectively. Gains and losses on these instruments are recorded in other comprehensive income, to the extent effective, until the underlying transaction is recognized in earnings. The earnings impact of the ineffective portion of these hedges was not material for the first quarter of 2012 and 2011.

Currency Rate Risk—Intercompany Loans and Dividends

We also use foreign currency forward exchange contracts to hedge exposures created by cross-currency intercompany loans and dividends. The translation adjustments related to these loans are recorded in other non-operating income or expense. The offsetting gains or losses on the related derivative contracts are also recorded in other non-operating income or expense. These contracts are decreased or increased as repayments are made or additional intercompany loans are extended or adjusted for intercompany dividend activity as necessary. The notional amount of these hedges was $22.0 million and $21.8 million at March 31, 2012 and December 31, 2011, respectively.

Interest Rate Risk

We utilize interest rate swaps to minimize the fluctuations in earnings caused by interest rate volatility. Interest expense on variable-rate liabilities increases or decreases as a result of interest rate fluctuations. On March 31, 2011 we entered into two interest rate swaps, on our Term Loan A and Term Loan B, with notional amounts of $100 million and $200 million, respectively, which mature in November 2015. Under the terms of the Term Loan A swap, we receive 3-month LIBOR and pay a fixed rate over the hedged period. Under the terms of the Term Loan B swap, we receive the greater of 3-month LIBOR or the 1% LIBOR Floor and pay a fixed rate over the hedged period. On March 27, 2012 we entered into an additional interest rate swap agreement with a notional amount of $250 million, maturing in November 2018, where we pay a fixed rate of 1.9275% over the hedged period. We also entered into a forward starting interest rate swap of $200 million from November 2015 to March 2018, where we pay a fixed rate of 2.810% over the hedged period. These swaps are designated as cash flow hedges against changes in LIBOR for a portion of our variable rate debt.

NOTE 15. PRODUCT WARRANTIES

We provide direct customer and end-user warranties for our products. These warranties cover manufacturing defects that would prevent the product from performing in line with its intended and marketed use. The terms of these warranties vary by product and generally provide for the repair or replacement of the defective product. We collect and analyze warranty claims data with a focus on the historic amount of claims, the products involved, the amount of time between the warranty claims and their respective sales and the amount of current sales. The following table summarizes the activity for the accrual of product warranties for the first three months of 2012 and 2011:

	2012			2011

NOTE 16. LITIGATION AND RELATED MATTERS

ENVIRONMENTAL MATTERS

Environmental Expenditures

Our manufacturing and research facilities are affected by various federal, state and local requirements relating to the discharge of materials and the protection of the environment. We make expenditures necessary for compliance with applicable environmental requirements at each of our operating facilities. These regulatory requirements continually change, therefore we cannot predict with certainty future expenditures associated with compliance with environmental requirements.

Environmental Remediation

Summary

We are actively involved in the investigation and/or remediation of environmental contamination under the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”), and state or international Superfund and similar type laws at several domestically- and internationally-owned, formerly owned and non-owned locations allegedly resulting from past industrial activity. In a few cases, we are one of several potentially responsible parties (“PRPs”) where we have agreed to jointly fund the required investigation and remediation, while preserving our defenses to the liability. We may also have rights of contribution or reimbursement from other parties or coverage under applicable insurance policies.

Estimates of our future liability at the environmental sites are based on evaluations of currently available facts regarding each individual site. We consider factors such as our activities associated with the site, existing technology, presently enacted laws and regulations and prior company experience in remediating contaminated sites. Although current law imposes joint and several liability on all parties at Superfund sites, our contribution to the remediation of these sites is expected to be limited by the number of other companies potentially liable for site remediation. As a result, our estimated liability reflects only our expected share. In determining the probability of contribution, we consider the solvency of other parties, whether liability is being disputed, the terms of any existing agreements and experience with similar matters, and the effect of our Chapter 11 reorganization upon the validity of the claim.

Specific Material Events

In August 2010, we entered into a Consent Order with the Oregon Department of Environmental Quality (“ODEQ”), along with Kaiser Gypsum Company, Inc. (“Kaiser”), and Owens Corning Sales LLC (“OC”), with respect to our St. Helens, Oregon ceilings facility, which was previously owned by Kaiser and then OC. The Consent Order, which replaces a previous order of the ODEQ requiring us to investigate and remediate hazardous substances present at the facility, requires that we and Kaiser complete a remedial investigation and feasibility study (“RI/FS”) on the portion of the site owned by us. The Consent Order further requires us, Kaiser and OC to conduct an RI/FS in the adjacent Scappoose Bay. Our current estimate of our future liability at the site relates to the investigation work required by the Consent Order and to the currently projected cost of possible remedies for certain portions of the site. However, neither the RI/FS for the portion of the property owned by us nor the Scappoose Bay is complete. At this time, we have determined that it is probable that additional corrective action for the portion of the property owned by us will be required. Such corrective action could result in additional costs greater than currently estimated and, consequently, those costs may be material. At this time, it is not possible to reasonably estimate the total costs that we may ultimately incur with respect to the Scappoose Bay, although such amounts may be material.

Costs and responsibilities for the RI/FS for certain portions of the St. Helens property owned by us continue to be shared with Kaiser pursuant to an agreement with Kaiser. Limited contributions are also being made by ODEQ pursuant to its settlement with OC for OC’s liabilities for the property. Contemporaneously with the execution of the Consent Order, we, Kaiser and OC also entered into a cost allocation agreement for the investigation and possible remediation of the Scappoose Bay.

The U.S. Environmental Protection Agency (“EPA”) has listed two landfills located on a portion of our ceilings facility in Macon, Georgia, along with the former Macon Naval Ordnance Plant landfill adjacent to our property, and portions of Rocky Creek (collectively the “Macon Site”) as a Superfund site on the National Priorities List due to the presence of contaminants, most notably PCBs. In September 2010, we entered into an Administrative Order on Consent for a Removal Action with the EPA to investigate PCB contamination in one of the landfills on our property that is a portion of the Superfund Site. Our current estimate of future liability includes costs for investigative work that we agreed to perform under the EPA order. We will ultimately incur expenses for closure or some form of remedial action with respect to the landfill. While those amounts are not estimable at this time, they may be material. Additionally, it is probable that we will incur field investigation, engineering and oversight costs associated with an RI/FS with respect to the remainder of the Superfund site, including Rocky Creek. We, along with other parties, may also ultimately incur costs in remedying contamination discovered during the RI/FS. At this time, it is not possible to reasonably estimate the amounts we may ultimately incur with respect to those activities, although such amounts may be material.

Summary of Financial Position

Liabilities of $ 7.3 million at March 31, 2012 and December 31, 2011 were recorded for potential environmental liabilities, on a global basis, that we consider probable and for which a reasonable estimate of the probable liability could be made. Where existing data is sufficient to estimate the liability, that estimate has been used; where only a range of probable liabilities is available and no amount within that range is more likely than any other, the lower end of the range has been used. As assessments and remediation activities progress at each site, these liabilities are reviewed to reflect new information as it becomes available. These liabilities are undiscounted.

The estimated liabilities above do not take into account any claims for recoveries from insurance or third parties. It is our policy to record probable recoveries that are either available through settlement or anticipated to be recovered through negotiation or litigation as assets in the Condensed Consolidated Balance Sheets. No amounts were recorded for probable recoveries at March 31, 2012 or December 31, 2011.

Actual costs to be incurred at identified sites may vary from our estimates. Based on our current knowledge of the identified sites, it is not possible to reasonably estimate future costs which may exceed amounts already recognized.

ANTIDUMPING AND COUNTERVAILING DUTY PETITION

In October 2010, a coalition of U.S. producers of multilayered wood flooring (not including Armstrong) filed antidumping (“AD”) and countervailing duty (“CVD”) petitions regarding multilayered hardwood flooring from China. The AD petition requested that the Department of Commerce impose duties of up to 269% on imports of multilayered hardwood flooring, which it claimed were needed to offset unfair pricing from Chinese imports that injure the U.S. industry. The CVD petition requested an unspecified level of duties be imposed on importers to offset alleged unfair subsidies provided by the Chinese government.

We produce multilayered wood flooring domestically and import multilayered wood flooring from suppliers in China. We also have a plant in China that manufactures multilayered wood flooring for export to the U.S. We are specifically mentioned in the AD and CVD petitions as an importer. Under the U.S. AD and CVD laws, a U.S. importer may be responsible for the payment of any antidumping and countervailing duties.

On October 12, 2011, the Department of Commerce announced its final determination for both CVD and AD investigations. The final rates are 1.5% (CVD) and 3.31% (AD). These rates will be retroactive to the dates of the preliminary determinations, and will be credited against the preliminary rates. Based on the final rates announced by the Department of Commerce, this matter is not expected to have a material adverse effect on our results of operations, financial position or cash flows.

A number of appeals have been filed by several parties challenging various aspects of the determinations by both the Department of Commerce and the International Trade Commission. Armstrong will participate in a number of these, and expects some or all of the appeals to be consolidated.

OTHER CLAIMS

We are involved in various lawsuits, claims, investigations and other legal matters from time to time that arise in the ordinary course of conducting business, including matters involving our products, intellectual property, relationships with suppliers, distributors, relationships with competitors, employees and other matters. While complete assurance cannot be given to the outcome of these proceedings, we do not currently believe that any of these matters, individually or in the aggregate, will have a material adverse effect on our financial condition, liquidity or results of operations.

NOTE 17. SPECIAL CASH DIVIDEND AND STOCK OPTION ADJUSTMENTS

On March 23, 2012, our Board of Directors declared a special cash dividend in the amount of $8.55 per share, or $508.3 million in the aggregate, of which $503.0 million was paid on April 10, 2012 to the shareholders of record as of April 3, 2012. The unpaid portion of the dividend relates to unvested employee shares and is reflected in current liabilities ($1.8 million) and other long term liabilities ($3.5 million) and will be paid when the underlying employee shares vest. The dividend was funded in part by existing cash and in part by the proceeds of additional debt issued under our Term Loan B. The dividend was recorded as a reduction of retained earnings to the extent that retained earnings were available at the dividend declaration date. Dividends in excess of retained earnings were recorded as a reduction of capital in excess of par value.

Under the terms of the 2011 Long Term Incentive Plan (“the Plan”), the Management Development and Compensation Committee of our Board of Directors is required to make equitable adjustments to stock option grants if there is a change in our capital structure. The special cash dividend qualified as a change to our capital structure under the terms of the Plan. We used the Black-Scholes option pricing model to determine the fair value of the awards before and after the special cash dividend, using consistent assumptions for the risk free rate of return, expected term, expected volatility and expected dividend yield. The stock prices used in the before and after calculations were $57.38 (the New York Stock Exchange Volume Weighted Average Price (“NYSE VWAP”) on March 29, 2012, the day before the ex-dividend date) and $49.21 (NYSE VWAP on March 30, 2012, the ex-dividend date), respectively. For all option grants, the fair value of the award before and after the dividend remained the same. Therefore there was no incremental cost recognized in our financial statements due to these award modifications.

The following changes were made to the options outstanding as a result of this change:

	Pre-Dividend Grant Terms			Post-Dividend Grant Terms
Year Granted	Number of Shares		Exercise Price	Number of Shares		Exercise Price
2006		262,418	$22.55		305,992	$19.34
2007		83,452	30.62		97,306	26.26
2008		171,792	21.85		200,318	18.74
2009		100,209	10.34		116,851	8.87
2010		608,278	26.21 – 29.23		709,309	22.48 – 25.07
2011		434,674	38.65 – 47.47		506,873	33.15 – 40.71
2012		403,750	50.38		470,805	43.21

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders

Armstrong World Industries, Inc.:

We have reviewed the accompanying condensed consolidated balance sheet of Armstrong World Industries, Inc. and subsidiaries (“the Company”) as of March 31, 2012, the related condensed consolidated statements of earnings and comprehensive income for the three-month periods ended March 31, 2012 and 2011, and the related condensed consolidated statements of cash flows and shareholders’ equity for the three-month periods ended March 31, 2012 and 2011. These condensed consolidated financial statements are the responsibility of the Company’s management.

We conducted our reviews in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our reviews, we are not aware of any material modifications that should be made to the condensed consolidated financial statements referred to above for them to be in conformity with U.S. generally accepted accounting principles.

We have previously audited, in accordance with standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of Armstrong World Industries, Inc. and subsidiaries as of December 31, 2011, and the related consolidated statements of earnings, cash flows, and equity for the year then ended (not presented herein); and in our report dated February 27, 2012, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated balance sheet as of December 31, 2011, is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Armstrong World Industries, Inc. (“AWI”) is a Pennsylvania corporation incorporated in 1891.

This discussion should be read in conjunction with the financial statements, the accompanying notes, the cautionary note regarding forward-looking statements and risk factors included in this report and our annual report on Form 10-K for the year ended December 31, 2011.

OVERVIEW

We are a leading global producer of flooring products and ceiling systems for use primarily in the construction and renovation of residential, commercial and institutional buildings. Through our United States (“U.S.”) operations and U.S. and international subsidiaries, we design, manufacture and sell flooring products (primarily resilient and wood) and ceiling systems (primarily mineral fiber, fiberglass and metal) around the world. We also design, manufacture and sell kitchen and bathroom cabinets in the U.S. As of March 31, 2012 we operated 32 manufacturing plants in eight countries, including 20 plants located throughout the U.S.

Reportable Segments

Building Products — produces suspended mineral fiber, soft fiber and metal ceiling systems for use in commercial, institutional and residential settings. In addition, our Building Products segment sources complementary ceiling products. Our products, which are sold worldwide, are available in numerous colors, performance characteristics and designs, and offer attributes such as acoustical control, rated fire protection and aesthetic appeal. Commercial ceiling materials and accessories are sold to ceiling systems contractors and to resale distributors. Residential ceiling products are sold in North America primarily to wholesalers and retailers (including large home centers). Suspension system (grid) products manufactured by Worthington Armstrong Venture (“WAVE”) are sold by both us and WAVE.

Resilient Flooring — produces and sources a broad range of floor coverings primarily for homes and commercial and institutional buildings. Manufactured products in this segment include vinyl sheet, vinyl tile and linoleum flooring. In addition, our Resilient Flooring segment sources and sells laminate flooring products, vinyl tile products, vinyl sheet products, adhesives, and installation and maintenance materials and accessories. Resilient Flooring products are offered in a wide variety of types, designs, and colors. We sell these products worldwide to wholesalers, large home centers, retailers, contractors and to the manufactured homes industry.

Wood Flooring — produces and sources wood flooring products for use in new residential construction and renovation, with some commercial applications in stores, restaurants and high-end offices. The product offering includes pre-finished solid and engineered wood floors in various wood species, and related accessories. Virtually all of our Wood Flooring sales are in North America. Our Wood Flooring products are generally sold to independent wholesale flooring distributors and large home centers.

Cabinets — produces kitchen and bathroom cabinetry and related products, which are used primarily in the U.S. residential new construction and renovation markets. Through our system of Company-owned and independent distribution centers and through direct sales to builders, our Cabinets segment provides design, fabrication and installation services to single and multi-family homebuilders, remodelers and consumers. All of Cabinets’ sales are in the U.S.

Unallocated Corporate — includes assets, liabilities, income and expenses that have not been allocated to the business units. Balance sheet items classified as Unallocated Corporate are primarily income tax related accounts, cash and cash equivalents, the Armstrong brand name, the U.S. prepaid pension cost and long-term debt. Expenses for our corporate departments and certain benefit plans are allocated to the reportable segments based on known metrics, such as specific activity, headcount, or net sales. The remaining items, which cannot be attributed to the reportable segments without a high degree of generalization, are reported in Unallocated Corporate.

Management’s Discussion and Analysis of Financial Condition and Results of Operations

See Note 2 to the Condensed Consolidated Financial Statements for additional financial information on our consolidated company and our reportable segments.

Factors Affecting Revenues

Markets. We compete in building material markets around the world. The majority of our sales are in North America and Europe. During the first quarter of 2012, our markets experienced the following:

• According to the U.S. Census Bureau, in the first quarter of 2012 housing starts in the U.S. residential market rose 18% compared to the first quarter of 2011 to 0.69 million units. Housing completions in the U.S. fell 0.2% year over year in the first quarter of 2012 with approximately 0.57 million units completed. The National Association of Realtors indicated that sales of existing homes grew 5.4% year over year in the first quarter of 2012 to 4.57 million units. Management estimates renovation activities declined in the U.S. during the first quarter of 2012, as indicated in part by the Remodeling Market Index provided by the National Association of Home Builders.

• According to the U.S. Census Bureau, for the value of new construction put in place, the rate of growth in the North American key commercial market, in nominal dollar terms, was 5.4% in January and February of 2012 when compared with the same period of 2011. Construction activity in the office, healthcare, and education segments grew 0.3%, 5.7%, and 5.2% respectively, in January and February of 2012 when compared with the same period of 2011.

• Central and Western European markets experienced significant declines, while Eastern European markets grew.

• Overall, Pacific Rim markets experienced growth, particularly in China and India, partially offset by declines in Australia.

Pricing Initiatives. We periodically modify prices in response to changes in costs for raw materials and energy, and to market conditions and the competitive environment. In certain cases, realized price increases are less than the announced price increases because of competitive reactions and changing market conditions. We estimate that prior pricing actions increased our first quarter of 2012 total consolidated net sales by approximately $8 million compared to the first quarter of 2011.

We announced price increases in each of our businesses that were effective in the first quarter of 2012. If raw material prices continue at, or rise from, current levels additional pricing actions may be announced.

Mix. Each of our businesses offers a wide assortment of products that are differentiated by style, design and performance attributes. Pricing and margins for products within the assortment vary. Changes in the relative quantity of products purchased at the different price points can impact year-to-year comparisons of net sales and operating income. We estimate mix changes increased our total consolidated net sales in the first quarter of 2012 by approximately $5 million when compared to the first quarter of 2011.

Factors Affecting Operating Costs

Operating Expenses. Our operating expenses are comprised of direct production costs (principally raw materials, labor and energy), manufacturing overhead costs, freight, costs to purchase sourced products and selling, general, and administrative (“SG&A”) expenses.

Our largest individual raw material expenditures are for lumber and veneers, PVC resins and plasticizers. Natural gas is also a significant input cost. Fluctuations in the prices of these inputs are generally beyond our control and have a direct impact on our financial results. In the first quarter of 2012, these input costs decreased operating income by approximately $3 million when compared to the same period of 2011.

26

Management’s Discussion and Analysis of Financial Condition and Results of Operations

We are committed to augmenting margin expansion through further cost elimination. Through manufacturing footprint reductions and aggressive application of projects designed to standardize, simplify and eliminate SG&A programs and policies, we are seeking to remove at least $185 million of manufacturing and SG&A costs by the end of 2012. Toward this end, we achieved $35 million of cost savings in 2010, another $115 million in savings in 2011, and expect to deliver another $35 million during 2012. We recorded expenses of approximately $16 million for these initiatives in the first quarter of 2012. During March of 2012, we decided to close our previously idled Building Products plant in Mobile, Alabama. We will continue to evaluate the efficiency of our manufacturing footprint and may take additional actions in support of our cost and standardization initiatives. The charges associated with our cost reduction initiatives may include severance and related termination benefits, fixed asset write-downs, asset impairments and accelerated depreciation and could be material to our financial statements. Even if we achieve these targeted savings, there is no assurance that our net operating results in the future will improve by this amount.

Employees

As of March 31, 2012 and December 31, 2011, we had approximately 9,100 full-time and part-time employees worldwide.

RESULTS OF OPERATIONS

Unless otherwise indicated, net sales in these results of operations are reported based upon the location where the sale was made. Please refer to Note 2 to the Condensed Consolidated Financial Statements for a reconciliation of operating income to consolidated earnings before income taxes.

2012 COMPARED TO 2011 CONSOLIDATED RESULTS

(dollar amounts in millions)

	Three Months Ended March 31,				Change is Favorable/
	2012		2011		(Unfavorable)
Net sales:
Americas	$	485.7	$	490.2		(0.9	)%
Europe		132.6		146.3		(9.4	)%
Pacific Rim		49.7		48.7		2.1	%
Total consolidated net sales	$	668.0	$	685.2		(2.5	)%
Operating income	$	41.6	$	52.1		(20.2	)%

Consolidated net sales decreased as improved pricing and favorable product mix were not able to offset volume declines.

Net sales in the Americas decreased as volume declines more than offset improved price and mix.

Net sales in the European markets declined significantly as modest price improvements were not able to offset sharp volume declines.

Net sales in the Pacific Rim increased as mix improvements offset lower volumes and pricing.

Cost of goods sold in 2012 was 78.3% of net sales, compared to 76.5% in 2011. The percentage increase was primarily the result of decreased sales and almost $15 million of accelerated depreciation and impairment charges associated with the closure of our Mobile, Alabama Building Products facility.

SG&A expenses in 2012 were $116.6 million, or 17.5% of net sales, compared to $120.1 million, or 17.5% of net sales, in 2011.

Equity earnings from our WAVE joint venture were $13.6 million in 2012, as compared to $16.4 million in 2011. See Note 6 to the Condensed Consolidated Financial Statements for further information.

Interest expense was $11.2 million in 2012 compared to $14.8 million in 2011. The decrease was primarily due to the first quarter 2011 amendment to our Term Loan B. The terms were modified from LIBOR plus 350 basis points with a 1.5% floor to LIBOR plus 300 basis points with a 1% floor.

27

Management’s Discussion and Analysis of Financial Condition and Results of Operations

Income tax expense was $13.0 million and $24.1 million for the first quarter of 2012 and 2011, respectively. The effective tax rate for the first quarter of 2012 was 41.7% as compared to a rate of 64.1% for the same period of 2011. The effective tax rate for 2012 was lower than 2011 due to the favorable tax impact from our mix of income from international operations and prior year additional state valuation allowances.

REPORTABLE SEGMENT RESULTS

Total segment net sales	$	303.1	$	306.9		(1.2	)%
Operating income	$	43.3	$	61.5		(29.6	)%

Net sales in the Americas increased as price and mix improvements were able to offset volume declines.

Net sales in Europe decreased as volume declines were only partially offset by improvements in price and mix.

Net sales in the Pacific Rim decreased as mix improvements only partially offset volume declines.

Operating income decreased as the first quarter of 2012 was impacted by almost $15 million of accelerated depreciation and impairment charges associated with the closure of our Mobile, Alabama facility, and approximately $4 million of costs associated with ending a labor lock out at our Marietta plant which was renegotiated during the fourth quarter of 2011. Price improvements and reductions in SG&A expenses were unable to offset lower volumes, lower earnings from WAVE, and the costs mentioned above.

Net sales in the Americas increased as improved product mix more than offset volume declines in our commercial markets.

Net sales in the European markets declined significantly as modest price improvements were not able to offset sharp volume declines and unfavorable mix.

Net sales in the Pacific Rim increased as favorable mix offset lower volumes and price.

28

Management’s Discussion and Analysis of Financial Condition and Results of Operations

Operating income increased as reduced manufacturing and S&GA expenses more than offset the impact of lower volumes and raw material cost increases. The 2011 operating loss included approximately $8.2 million of charges in our European Resilient Flooring business related to severance and restructuring related activities.

Wood Flooring

Total segment net sales	$	105.6	$	111.0		(4.9	)%
Operating income	$	2.5	$	3.5		(28.6	)%

Net sales decreased as volumes, price and mix were unfavorable compared to the prior year. Lower sales to Big Box customers were only partially offset by higher sales to independent retail customers. Shipments were negatively impacted as orders outpaced production capacity. To address the shipment backlog, we are adding back additional crewing and staffing at several plants. If not for capacity constraints, we believe first quarter 2012 net sales would have increased over the prior year. Operating income decreased primarily due to the margin impact of lower volumes.

Operating income decreased primarily due to the margin impact of lower volumes and price.

Total segment net sales	$	32.0		$	32.6			(1.8	)%
Operating (loss)	$	(1.1	)	$	(0.8	)		(37.5	)%

Net sales decreased as mix improvements only partially offset volume declines.

Operating loss increased as higher input costs and lower volumes were only partially offset by favorable mix.

Unallocated Corporate

Unallocated corporate expense of $13.8 million in the first quarter of 2012 increased from $10.8 million in the prior year primarily due to a $3.5 million lower pension credit.

FINANCIAL CONDITION AND LIQUIDITY

Cash Flow

Operating activities in the first quarter of 2012 used $33.1 million of cash compared to $36.1 million in the first quarter of 2011.

Net cash used by investing activities was $15.5 million for the first quarter of 2012 compared to $7.8 million for the first quarter of 2011. The increase in cash used was primarily due to higher purchases of property, plant and equipment partially offset by increased returns of investment from WAVE.

Net cash provided by financing activities was $249.6 million for the first quarter of 2012, compared to $32.9 million used during the first quarter of 2011. Net cash provided in 2012 was impacted by $251.9 million of long-term debt issued (see Liquidity section for further information). Net cash used in 2011 was impacted by $25.0 million of payments on our revolving credit facility.

Management’s Discussion and Analysis of Financial Condition and Results of Operations

Liquidity

Our liquidity needs for operations vary throughout the year. We retain lines of credit to facilitate our seasonal cash flow needs, since cash flow is generally lower during the first and fourth quarters of our fiscal year. On March 22, 2012, we amended our $1.05 billion senior credit facility arranged by Merrill Lynch, Pierce, Fenner & Smith, Inc., J.P. Morgan Securities, Inc., and Barclays Capital. We added $250 million to our existing Term Loan B facility. This amended facility is comprised of a $250 million revolving credit facility (with a $150 million sublimit for letters of credit), a $250 million Term Loan A and an $800 million Term Loan B. This $1.3 billion senior credit facility is secured by U.S. personal property, the capital stock of material U.S. subsidiaries, and a pledge of 65% of the stock of our material first tier foreign subsidiaries. The only significant change to existing terms, conditions and covenants pertained to the consolidated leverage ratio covenant, which is described below.

In connection with the additional $250 million Term Loan B borrowings, we paid $7.6 million for bank, legal and other fees. This amount was capitalized and is being amortized into interest expense over the life of the loan.

The senior credit facility includes two financial covenants that require the ratio of consolidated earnings before interest, taxes, depreciation and amortization (“EBITDA”) to consolidated cash interest expense minus cash consolidated interest income (“consolidated interest coverage ratio”) to be greater than or equal to 3.0 to 1.0 and require the ratio of consolidated funded indebtedness minus AWI and domestic subsidiary unrestricted cash and cash equivalents up to $100 million to consolidated EBITDA (“consolidated leverage ratio”) to be less than or equal to 4.5 to 1.0 through December 31, 2013, 4.0 to 1.0 after December 31, 2013 through March 31, 2015 and 3.75 to 1.0 after March 31, 2015. We currently believe that default under these covenants is unlikely. Fully borrowing under our revolving credit facility would not violate these covenants. During the first quarter of 2012 we were in compliance with all covenants of the credit agreement.

The Revolving Credit and Term Loan A portions are currently priced at a spread of 3.00% over LIBOR and the Term Loan B portion (as amended) is priced at 3.00% over LIBOR with a 1.00% LIBOR floor for its entire term. The Term Loan A and Term Loan B were both fully drawn and are currently priced on a variable interest rate basis. On March 31, 2011, we entered into two interest rate swaps, on our Term Loan A and Term Loan B, with notional amounts of $100 million and $200 million, respectively, which mature in November 2015. Under the terms of the Term Loan A swap, we receive 3-month LIBOR and pay a fixed rate over the hedged period. Under the terms of the Term Loan B swap, we receive the greater of 3-month LIBOR or the 1% LIBOR Floor and pay a fixed rate over the hedged period. On March 27, 2012 we entered into an additional interest rate swap agreement with a notional amount of $250 million, maturing in November 2018, where we pay a fixed rate of 1.9275% over the hedged period. We also entered into a forward starting interest rate swap of $200 million from November 2015 to March 2018, where we pay a fixed rate of 2.810% over the hedged period. These swaps are designated as cash flow hedges against changes in LIBOR for a portion of our variable rate debt. The unpaid balances of Term Loan A, the Revolving Credit and Term Loan B of the credit facility may be prepaid without penalty at the maturity of their respective interest reset periods. Any amounts prepaid on the Term Loan A or Term Loan B may not be re-borrowed.

Beginning in 2013, mandatory prepayments are required under the senior credit facility pursuant to a year end annual leverage test, under which, if our consolidated leverage ratio is greater than 2.0 to 1.0, but less than 2.5 to 1.0, we would be required to make a prepayment of 25% of Consolidated Excess Cash Flow, as defined by the credit agreement. If our consolidated leverage ratio is greater than 2.5 to 1.0, the prepayment amount would be 50% of Consolidated Excess Cash Flow.

As of March 31, 2012, we had $683.3 million of cash and cash equivalents, $587.5 million in the U.S. and $95.8 million in various foreign jurisdictions.

Our April 16, 2012 debt rating from S&P is BB- (stable) and from Moody’s is B1 (stable).

On March 23, 2012, our Board of Directors declared a special cash dividend in the amount of $8.55 per share, or $508.3 million in the aggregate, of which $503.0 million was paid on April 10, 2012. Payment of an additional $5.3 million of the dividend is expected to be made when the underlying employee shares vest. The dividend was funded in part by surplus cash on our balance sheet, and in part by the proceeds of additional debt issued under our Term Loan B.

30

Management’s Discussion and Analysis of Financial Condition and Results of Operations

On December 10, 2010, we established a $100 million Receivables Securitization Program. AWI and its subsidiary, Armstrong Hardwood Flooring Company, sold their U.S. receivables to Armstrong Receivables Company LLC (“ARC”), a Delaware entity that is consolidated in these financial statements. ARC financed those receivables through Credit Agricole Corporate and Investment Bank, with a maximum commitment of $100 million. In addition to the financing of receivables by Credit Agricole, under the documentation establishing the program, Credit Agricole could also issue letters of credit at the request of ARC. The purchase and letter of credit commitments under the program were originally set to expire in December 2013, subject to possible extensions thereafter. In December 2011, this facility was assigned to the Bank of Nova Scotia and extended to 2014.

On December 16, 2010, we issued $35.0 million of Recovery Zone Facility bonds through Jackson County, West Virginia, to finance the construction of our new mineral wool plant. These tax exempt bonds are seven day variable rate demand notes backed by a letter of credit. These bonds mature in 2041.

On March 31, 2012, we had outstanding letters of credit totaling $70.2 million, of which $19.4 million was issued under the revolving credit facility, $50.6 million was issued under the securitization facility and $0.2 million was issued by other banks of international subsidiaries. Letters of credit are issued to third party suppliers, insurance and financial institutions and typically can only be drawn upon in the event of AWI’s failure to pay its obligations to the beneficiary.

	As of March 31, 2012
Foreign Financing Arrangements	Limit		Used		Available
Lines of Credit Available for Borrowing	$	19.0		—	$	19.0
Lines of Credit Available for Letters of Credit		2.3	$	0.8		1.5
Total	$	21.3	$	0.8	$	20.5

These lines of credit are uncommitted, and poor operating results or credit concerns at the related foreign subsidiaries could result in the lines being withdrawn by the lenders. We have historically been able to maintain and, as needed, replace credit facilities to support our foreign operations.

Our Board of Directors previously approved the construction of a U.S. mineral wool plant to supply our Building Products plants, the allocation of capital to double our Building Products production capacity in China, and the construction of two flooring plants in China. Total capital spending for these projects is currently projected to be approximately $210 million. Through March 31, 2012, we have incurred approximately $93 million related to these projects with most of the remaining spending to occur in 2012. The mineral wool plant began operating in April 2012.

In February 2012, our Board of Directors approved the construction of a mineral fiber ceiling plant in Russia. Total capital spending is expected to be approximately $100 million. The spending will be incurred through 2015 with the majority of the spending in 2013.

We believe that cash on hand and cash generated from operations, together with lines of credit, availability under our securitization program, and the availability under the $250 million revolving credit facility, will be adequate to address our foreseeable liquidity needs based on current expectations of our business operations, capital expenditures and scheduled payments of debt obligations.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

For information regarding our exposure to certain market risks, see Item 7A, “Quantitative and Qualitative Disclosures About Market Risk,” in our 2011 annual report on Form 10-K. There have been no material changes in our financial instruments or market risk exposures since December 31, 2011.

ITEM 4. CONTROLS AND PROCEDURES

(a) Evaluation of Disclosure Controls and Procedures. The Securities and Exchange Commission defines the term “disclosure controls and procedures” to mean a company’s controls and other procedures that are designed to ensure that information required to be disclosed in the reports that it files or submits under the Securities Exchange Act of 1934, as amended (the “Act”), is recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange Commission’s rules and forms. Based on the evaluation of the effectiveness of our disclosure controls and procedures by our management, with the participation of our principal executive officer and our chief financial officer, as of March 31, 2012, our principal executive officer and our chief financial officer have concluded that our disclosure controls and procedures were effective to ensure that information required to be disclosed in the reports that we file or submit under the Act is recorded, processed, summarized and reported within the time periods specified in the Commission’s rules and forms.

(b) Changes in Internal Control Over Financial Reporting. Except as described below there have been no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Act) that occurred during the fiscal quarter ended March 31, 2012 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

In an effort to make our IT, finance and accounting functions more efficient, increase related capabilities and generate cost savings, we continued to outsource a significant portion of our IT infrastructure and certain finance and accounting functions to separate third party service providers during the first quarter of 2012. In connection with the outsourcing of these functions, we performed significant pre-implementation planning, design and testing. We continued our oversight and testing during the implementation to ensure the effectiveness of internal control over financial reporting.

(c) all decisions with respect to future grants of options, if any, will be at the sole discretion of the Committee;

(d) the Grantee is voluntarily participating in the Plan;

(g) the Option and the shares of Company Stock subject to the Option are not intended to replace any pension rights or compensation;

(h) the grant of the Option and the Grantee’s participation in the Plan will not be interpreted to form an employment contract or relationship with the Employer;

(j) the Grantee shall have no rights, claim or entitlement to compensation or damages as a result of the Grantee’s cessation of employment for any reason whatsoever, whether or not in breach of contract or local labor law, insofar as these rights, claim or entitlement arise or may arise from the Grantee’s ceasing to have rights under or be entitled to receive shares of Company Stock under or ceasing to have the opportunity to participate in the Plan as a result of such cessation or loss or diminution in value of the Option or any of the shares of Company Stock acquired thereunder as a result of such cessation, and the Grantee irrevocably releases the Employer from any such rights, entitlement or claim that may arise. If, notwithstanding the foregoing, any such right or claim is found by a court of competent jurisdiction to have arisen, then the Grantee shall be deemed to have irrevocably waived the Grantee’s entitlement to pursue such rights or claim.

These terms and conditions are in addition to the terms and conditions set forth in the Grant Conditions. This Addendum may also include information regarding certain other issues of which the Grantee should be aware with respect to the Grantee’s participation in the Plan. Capitalized terms used but not defined herein shall have the meanings assigned to them in the Grant Conditions (of which this Addendum is a part) and the Plan.

Australia

(a) The Grant Letter and Grant Conditions have been prepared for the purpose of providing general information, without taking account of the Grantee’s objectives, financial situation or needs. The Grantee should, before making any decisions, consider the appropriateness of the information in the Grant Letter and Grant Conditions, and seek professional advice, having regard to the Grantee’s objectives, financial situation and needs.

Les parties reconnaissent avoir exigé la rédaction en anglais de cette convention, ainsi que de tous documents exécutés, avis donnés et procédures judiciaries intentées, directement ou indirectement, relativement à ou suite à la présente convention.

Netherlands

The Grantee should be aware of the Dutch insider trading rules, which may impact the sale of shares of Company Stock acquired under the Option. In particular, the Grantee may be prohibited from effecting certain share transactions if the Grantee has insider information regarding the Company. Below is a discussion of the applicable restrictions. The Grantee is advised to read the discussion carefully to determine whether the insider rules apply to the Grantee. If it is uncertain whether the insider rules apply, the Company recommends that the Grantee consult with his or her personal legal advisor. Please note that the Company cannot be held liable if the Grantee violates the Dutch insider rules. The Grantee is responsible for ensuring compliance with these rules.

By entering into this Agreement and participating in the Plan, the Grantee acknowledges having read and understood the notification below and acknowledges that it is his or her own responsibility to comply with the Dutch insider trading rules, as discussed herein.

PROHIBITION AGAINST INSIDER TRADING.

Dutch securities laws prohibit insider trading. Under Article 5.56 of the Dutch Financial Supervision Act, anyone who has “inside information” related to the Company is prohibited from effectuating a transaction in securities in or from the Netherlands. “Inside information” is knowledge of specific information concerning the issuer to which the securities relate that is not public and which, if published, would reasonably be expected to affect the share price, regardless of the actual effect on the price. The insider could be any employee of the Company or an affiliate in the Netherlands who has inside information as described above.

Given the broad scope of the definition of inside information, certain employees of the Company working at its Dutch affiliate may have inside information and thus, would be prohibited from effectuating a transaction in securities in the Netherlands at a time when he or she had such inside information

The Employer will withhold shares of Company Stock payable hereunder to satisfy the withholding obligation for Taxes on amounts payable in shares, unless the Grantee provides a payment to the Employer to cover such Taxes, in accordance with procedures established by the Committee. The share withholding amount shall not exceed the Grantee’s minimum applicable withholding amount for Taxes.

(b) Regardless of any action the Employer takes with respect to any such Taxes, the Grantee acknowledges that the ultimate liability for all such Taxes legally due by the Grantee is and remains the Grantee’s responsibility and that the Employer (i) makes no representations or undertakings regarding the treatment of any Taxes in connection with any aspect of the Time- Based Units, including the grant, vesting or settlement of the Time-Based Units and the subsequent sale of any shares of Company Stock acquired at settlement; and (ii) does not commit to structure the terms of the grant or any aspect of the Time-Based Units to reduce or eliminate the Grantee’s liability for Taxes. Further, if the Grantee has become subject to tax in more than one jurisdiction between the date of grant and the date of any relevant taxable event, the Grantee acknowledges that the Employer may be required to collect, withhold or account for Taxes in more than one jurisdiction.

17. No Entitlement or Claims for Compensation. In connection with the acceptance of the grant of the Time-Based Units under the Grant Letter and these Grant Conditions, the Grantee acknowledges the following:

(a) the Plan is established voluntarily by the Company, the grant of the Time-Based Units under the Plan is made at the discretion of the Committee and the Plan may be modified, amended, suspended or terminated by the Company at any time;

(b) the grant of the Time-Based Units under the Plan is voluntary and occasional and does not create any contractual or other right to receive future grants of Time-Based Units, or benefits in lieu of them, even if Time-Based Units have been granted repeatedly in the past;

(c) all decisions with respect to future grants of Time-Based Units, if any, will be at the sole discretion of the Committee;

(d) the Grantee is voluntarily participating in the Plan;

(e) the Time-Based Units and any shares of Company Stock acquired under the Plan are extraordinary items that do not constitute compensation of any kind for services of any kind rendered to the Employer (including, as applicable, the Grantee’s employer) and which are outside the scope of the Grantee’s employment contract, if any;

4

(f) the Time-Based Units and any shares of Company Stock acquired under the Plan are not to be considered part of the Grantee’s normal or expected compensation or salary for any purpose, including, but not limited to, calculating any severance, resignation, termination, payment in lieu of notice, redundancy, end of service payments, bonuses, long-service awards, pension or retirement or welfare benefits or similar payments;

(g) the Time-Based Units and the shares of Company Stock subject to the award are not intended to replace any pension rights or compensation;

(h) the grant of Time-Based Units and the Grantee’s participation in the Plan will not be interpreted to form an employment contract or relationship with the Employer;

(i) the future value of the underlying shares of Company Stock is unknown and cannot be predicted with certainty. If the Grantee vests in the Time-Based Units and receives shares of Company Stock, the value of the acquired shares may increase or decrease. The Grantee understands that the Company is not responsible for any foreign exchange fluctuation between the United States Dollar and the Grantee’s local currency that may affect the value of the Time-Based Units or the shares of Company Stock; and

(j) the Grantee shall have no rights, claim or entitlement to compensation or damages as a result of the Grantee’s cessation of employment for any reason whatsoever, whether or not in breach of contract or local labor law, insofar as these rights, claim or entitlement arise or may arise from the Grantee’s ceasing to have rights under or be entitled to receive shares of Company Stock under or ceasing to have the opportunity to participate in the Plan as a result of such cessation or loss or diminution in value of the Time-Based Units or any of the shares of Company Stock acquired thereunder as a result of such cessation, and the Grantee irrevocably releases the Employer from any such rights, entitlement or claim that may arise. If, notwithstanding the foregoing, any such right or claim is found by a court of competent jurisdiction to have arisen, then the Grantee shall be deemed to have irrevocably waived the Grantee’s entitlement to pursue such rights or claim.

18. Addendum. Notwithstanding any provisions in these Grant Conditions, the Time-Based Units shall be subject to any special terms and conditions set forth in any Addendum to this Agreement for the Grantee’s country. Moreover, if the Grantee relocates to one of the countries included in the Addendum, the special terms and conditions for such country will apply to the Grantee, to the extent the Company determines that the application of such terms and conditions is necessary for legal or administrative reasons.

These terms and conditions are in addition to the terms and conditions set forth in the Grant Conditions. This Addendum may also include information regarding certain other issues of which the Grantee should be aware with respect to the Grantee’s participation in the Plan. Capitalized terms used but not defined herein shall have the meanings assigned to them in the Grant Conditions (of which this Addendum is a part) and the Plan.

Australia

(a) The Grant Letter and Grant Conditions have been prepared for the purpose of providing general information, without taking account of the Grantee’s objectives, financial situation or needs. The Grantee should, before making any decisions, consider the appropriateness of the information in the Grant Letter and Grant Conditions, and seek professional advice, having regard to the Grantee’s objectives, financial situation and needs.

Les parties reconnaissent avoir exigé la rédaction en anglais de cette convention, ainsi que de tous documents exécutés, avis donnés et procédures judiciaries intentées, directement ou indirectement, relativement à ou suite à la présente convention.

Netherlands

The Grantee should be aware of the Dutch insider trading rules, which may impact the sale of shares of Company Stock acquired under the Time-Based Units. In particular, the Grantee may be prohibited from effecting certain share transactions if the Grantee has insider information regarding the Company. Below is a discussion of the applicable restrictions. The Grantee is advised to read the discussion carefully to determine whether the insider rules apply to the Grantee. If it is uncertain whether the insider rules apply, the Company recommends that the Grantee consult with his or her personal legal advisor. Please note that the Company cannot be held liable if the Grantee violates the Dutch insider rules. The Grantee is responsible for ensuring compliance with these rules.

By entering into this Agreement and participating in the Plan, the Grantee acknowledges having read and understood the notification below and acknowledges that it is his or her own responsibility to comply with the Dutch insider trading rules, as discussed herein.

PROHIBITION AGAINST INSIDER TRADING.

Dutch securities laws prohibit insider trading. Under Article 5.56 of the Dutch Financial Supervision Act, anyone who has “inside information” related to the Company is prohibited from effectuating a transaction in securities in or from the Netherlands. “Inside information” is knowledge of specific information concerning the issuer to which the securities relate that is not public and which, if published, would reasonably be expected to affect the share price, regardless of the actual effect on the price. The insider could be any employee of the Company or an affiliate in the Netherlands who has inside information as described above.

Given the broad scope of the definition of inside information, certain employees of the Company working at its Dutch affiliate may have inside information and thus, would be prohibited from effectuating a transaction in securities in the Netherlands at a time when he or she had such inside information

If and to the extent that the underlying Performance Units are forfeited, all related Dividend Equivalents shall also be forfeited.

9. No Right to Continued Employment. The grant of Performance Units shall not confer upon the Grantee any right to continued employment with the Employer or interfere with the right of the Employer to terminate the Grantee’s employment at any time.

10. Incorporation of Plan by Reference. The Grant Letter and these Grant Conditions are made pursuant to the terms of the Plan, the terms of which are incorporated herein by reference, and shall in all respects be interpreted in accordance therewith. The decisions of the Committee shall be conclusive upon any question arising hereunder. The Grantee’s receipt of the Performance Units constitutes the Grantee’s acknowledgment that all decisions and determinations of the Committee with respect to the Plan, the Grant Letter, these Grant Conditions, and the Performance Units shall be final and binding on the Grantee and any other person claiming an interest in the Performance Units.

11. Withholding Taxes.

(a) The Employer shall have the right, and the Grantee hereby authorizes the Employer, to deduct from all payments made hereunder and from other compensation an amount equal to all taxes, social insurance, payroll tax, contributions, payment on account obligations or other amounts required by law to be collected, withheld or accounted for with respect to the Performance Units (the “Taxes”).

(b) Regardless of any action the Employer takes with respect to any such Taxes, the Grantee acknowledges that the ultimate liability for all such Taxes legally due by the Grantee is and remains the Grantee’s responsibility and that the Employer (i) makes no representations or undertakings regarding the treatment of any Taxes in connection with any aspect of the Performance Units, including the grant, vesting or settlement of the Performance Units; and (ii) does not commit to structure the terms of the grant or any aspect of the Performance Units to reduce or eliminate the Grantee’s liability for Taxes. Further, if the Grantee has become subject to tax in more than one jurisdiction between the date of grant and the date of any relevant taxable event, the Grantee acknowledges that the Employer may be required to collect, withhold or account for Taxes in more than one jurisdiction.

15. No Entitlement or Claims for Compensation. In connection with the acceptance of the grant of the Performance Units under the Grant Letter and these Grant Conditions, the Grantee acknowledges the following:

(a) the Plan is established voluntarily by the Company, the grant of the Performance Units under the Plan is made at the discretion of the Committee and the Plan may be modified, amended, suspended or terminated by the Company at any time;

(b) the grant of the Performance Units under the Plan is voluntary and occasional and does not create any contractual or other right to receive future grants of Performance Units, or benefits in lieu of them, even if Performance Units have been granted repeatedly in the past;

(c) all decisions with respect to future grants of Performance Units, if any, will be at the sole discretion of the Committee;

(d) the Grantee is voluntarily participating in the Plan;

(e) the Performance Units are extraordinary items that do not constitute compensation of any kind for services of any kind rendered to the Employer (including, as applicable, the Grantee’s employer) and which are outside the scope of the Grantee’s employment contract, if any;

(f) the Performance Units are not to be considered part of the Grantee’s normal or expected compensation or salary for any purpose, including, but not limited to, calculating any severance, resignation, termination, payment in lieu of notice, redundancy, end of service payments, bonuses, long-service awards, pension or retirement or welfare benefits or similar payments;

4

(g) the Performance Units are not intended to replace any pension rights or compensation;

(h) the grant of Performance Units and the Grantee’s participation in the Plan will not be interpreted to form an employment contract or relationship with the Employer;

(i) the future value of the underlying shares of Company Stock is unknown and cannot be predicted with certainty. The Grantee understands that the Company is not responsible for any foreign exchange fluctuation between the United States Dollar and the Grantee’s local currency that may affect the value of the Performance Units; and

(j) the Grantee shall have no rights, claim or entitlement to compensation or damages as a result of the Grantee’s cessation of employment for any reason whatsoever, whether or not in breach of contract or local labor law, insofar as these rights, claim or entitlement arise or may arise from the Grantee’s ceasing to have rights under or be entitled to receive payment under or ceasing to have the opportunity to participate in the Plan as a result of such cessation or loss or diminution in value of the Performance Units as a result of such cessation, and the Grantee irrevocably releases the Employer from any such rights, entitlement or claim that may arise. If, notwithstanding the foregoing, any such right or claim is found by a court of competent jurisdiction to have arisen, then the Grantee shall be deemed to have irrevocably waived the Grantee’s entitlement to pursue such rights or claim.

ARMSTRONG WORLD INDUSTRIES, INC.

2011 LONG-TERM INCENTIVE PLAN

PERFORMANCE RESTRICTED STOCK UNIT GRANT

TERMS AND CONDITIONS

1. Grant.

(a) Subject to the terms set forth below, Armstrong World Industries, Inc. (the “Company”) has granted to the designated employee (the “Grantee”) a target award (the “Target Award”) of performance-based restricted stock units (the “Performance Units”) as specified in the 2012 Long-Term Performance Restricted Stock Unit Grant letter to which these Grant Conditions relate (the “Grant Letter”). The “Date of Grant” is February 28, 2012. The Performance Units are Stock Units with respect to common stock of the Company (“Company Stock”).

(b) The Performance Units shall be earned, vested and payable if and to the extent that the Return on Invested Capital performance goals set forth in the Grant Letter (the “Performance Goals”), employment conditions and other terms of these Grant Conditions are met. The “Performance Period” for which the attainment of the Performance Goals will be measured is the period beginning January 1, 2012 and ending December 31, 2014.

(c) These Terms and Conditions (the “Grant Conditions”) are part of the Grant Letter. This grant is made under the Armstrong World Industries, Inc. 2011 Long-Term Incentive Plan (the “Plan”). Any terms not defined herein shall have the meanings set forth in the Plan.

2. Vesting.

(a) The Grantee shall earn and vest in a number of Performance Units based on the attainment of the Performance Goals as of the end of the Performance Period, provided that the Grantee continues to be employed by the Company or its subsidiaries or affiliates (collectively the “Employer”) through December 31, 2014 (the “Vesting Date”).

(b) At the end of the Performance Period, the Management Development and Compensation Committee (the “Committee”) will determine whether and to what extent the Performance Goals have been met and the amount earned with respect to the Performance Units. The Grantee can earn up to 175% of the Target Award based on attainment of the Performance Goals, as set forth in the Grant Letter.

(c) Except as described below, no Performance Units shall vest prior to the Vesting Date, and if the Performance Goals are not attained at the end of the Performance Period, the Performance Units shall be immediately forfeited and shall cease to be outstanding.

3. Termination of Employment.

(a) Except as described below, if the Grantee ceases to be employed by the Employer prior to the Vesting Date, the Performance Units shall be forfeited as of the termination date and shall cease to be outstanding.

(b) If, after December 31, 2012, the Grantee ceases to be employed by the Employer prior to the Vesting Date on account of Retirement (as defined below), Involuntary Termination (as defined below) or death, or the Grantee incurs a Long-Term Disability (as defined below), the Grantee shall earn a pro-rata portion of the outstanding Performance Units based on attainment of the Performance Goals, as determined following the end of the Performance Period, provided such vesting does not result in a violation of any age discrimination or other applicable law. The pro-rated portion shall be determined by calculating the number of Performance Units earned based on attainment of the Performance Goals, multiplied by a fraction, the numerator of which is the number of months following January 1, 2012 and up to the Grantee’s termination date in which the Grantee was employed by the Employer and the denominator of which is 36. A partial month shall count as a full month for purposes of this calculation. The pro-rated earned Performance Units shall be paid as described in Section 6.

4. Change in Control Involuntary Termination. Subject to Section 14 of the Plan, if the Grantee has an Involuntary Termination upon or within two years after a Change in Control, and prior to the Vesting Date, the Grantee’s outstanding Performance Units shall vest at their Target Award value and shall be paid within 60 days after such Involuntary Termination, notwithstanding Sections 3 and 6 herein. The Company shall issue shares of Company Stock equal to the vested Performance Units, subject to applicable withholding for Taxes.

5. Definitions. For purposes of these Grant Conditions and the Grant Letter:

(a) “Cause” shall mean any of the following, as determined in the sole discretion of the Employer: (1) commission of a felony or a crime involving moral turpitude; (2) fraud, dishonesty, misrepresentation, theft or misappropriation of funds with respect to the Employer; (3) violation of the Employer’s Code of Conduct or employment policies, as in effect from time to time; (4) breach of any written noncompetition, confidentiality or nonsolicitation covenant of the Grantee with respect to the Employer; or (5) gross negligence or misconduct in the performance of the Grantee’s duties with the Employer.

(b) “Involuntary Termination” shall mean the Employer’s termination of the Grantee’s employment other than for Cause.

(c) “Long-Term Disability” shall mean the Grantee is receiving long-term disability benefits under the Employer’s long-term disability plan.

(d) “Retirement” shall mean the Grantee’s termination of employment other than for Cause after the Grantee has attained age 55 and has completed five years of service with the Employer.

2

6. Payment. At the end of the Performance Period, if the Committee certifies that the Performance Goals and other conditions to payment of the Performance Units have been met, the Company shall issue shares of Company Stock to the Grantee equal to the vested earned Performance Units. Payment shall be made between January 1, 2015 and March 15, 2015, subject to applicable withholding for Taxes. Any fractional shares will be rounded up to the nearest whole share. Notwithstanding any provision of the Plan, the Grant Letter or these Grant Conditions to the contrary, the Performance Units shall be settled in shares of Company Stock only.

7. Dividend Equivalents. Dividend Equivalents shall accrue with respect to Performance Units and shall be payable subject to the same vesting terms and other conditions as the Performance Units to which they relate. Dividend Equivalents shall be credited on the Performance Units when dividends are declared on shares of Company Stock from the Date of Grant until the payment date for the vested Performance Units. The Company will keep records of Dividend Equivalents in a non-interest bearing cash account for the Grantee. No interest will be credited to any such account. Vested Dividend Equivalents shall be paid in cash at the same time and subject to the same terms as the underlying vested Performance Units. If and to the extent that the underlying Performance Units are forfeited, all related Dividend Equivalents shall also be forfeited.

8. Delivery of Shares. The Company’s obligation to deliver shares upon the vesting of the Performance Units shall be subject to applicable laws, rules and regulations and also to such approvals by governmental agencies as may be deemed appropriate to comply with relevant securities laws and regulations.

9. No Shareholder Rights. No shares of Company Stock shall be issued to the Grantee on the Date of Grant, and the Grantee shall not be, nor have any of the rights or privileges of, a shareholder of the Company with respect to any Performance Units.

10. No Right to Continued Employment. The grant of Performance Units shall not confer upon the Grantee any right to continued employment with the Employer or interfere with the right of the Employer to terminate the Grantee’s employment at any time.

11. Incorporation of Plan by Reference. The Grant Letter and these Grant Conditions are made pursuant to the terms of the Plan, the terms of which are incorporated herein by reference, and shall in all respects be interpreted in accordance therewith. The decisions of the Committee shall be conclusive upon any question arising hereunder. The Grantee’s receipt of the Performance Units constitutes the Grantee’s acknowledgment that all decisions and determinations of the Committee with respect to the Plan, the Grant Letter, these Grant Conditions, and the Performance Units shall be final and binding on the Grantee and any other person claiming an interest in the Performance Units.

12. Withholding Taxes.

(a) The Employer shall have the right, and the Grantee hereby authorizes the Employer, to deduct from all payments made hereunder and from other compensation an amount equal to the federal (including FICA), state, local and foreign taxes, social insurance, payroll tax, contributions, payment on account obligations or other amounts required by law to be collected, withheld or accounted for with respect to the Performance Units (the “Taxes”). The Employer will withhold shares of Company Stock payable hereunder to satisfy the withholding obligation for Taxes on amounts payable in shares, unless the Grantee provides a payment to the Employer to cover such Taxes, in accordance with procedures established by the Committee. The share withholding amount shall not exceed the Grantee’s minimum applicable withholding amount for Taxes.

(b) Regardless of any action the Employer takes with respect to any such Taxes, the Grantee acknowledges that the ultimate liability for all such Taxes legally due by the Grantee is and remains the Grantee’s responsibility and that the Employer (i) makes no representations or undertakings regarding the treatment of any Taxes in connection with any aspect of the Performance Units, including the grant, vesting or settlement of the Performance Units and the subsequent sale of any shares of Company Stock acquired at settlement; and (ii) does not commit to structure the terms of the grant or any aspect of the Performance Units to reduce or eliminate the Grantee’s liability for Taxes. Further, if the Grantee has become subject to tax in more than one jurisdiction between the date of grant and the date of any relevant taxable event, the Grantee acknowledges that the Employer may be required to collect, withhold or account for Taxes in more than one jurisdiction.

13. Company Policies. All amounts payable under the Grant Letter and these Grant Conditions shall be subject to any applicable clawback or recoupment policies, share trading policies and other policies that may be implemented by the Company’s Board of Directors from time to time.

14. Assignment. The Grant Letter and these Grant Conditions shall bind and inure to the benefit of the successors and assignees of the Company. The Grantee may not sell, assign, transfer, pledge or otherwise dispose of the Performance Units, except to a successor grantee in the event of the Grantee’s death.

15. Section 409A. The Grant Letter and these Grant Conditions are intended to comply with section 409A of the Internal Revenue Code or an exemption, consistent with Section 20(h) of the Plan.

16. Governing Law. The validity, construction, interpretation and effect of the Grant Letter and these Grant Conditions shall be governed by, and determined in accordance with, the applicable laws of the Commonwealth of Pennsylvania, excluding any conflicts or choice of law rule or principle.

4

17. No Entitlement or Claims for Compensation. In connection with the acceptance of the grant of the Performance Units under the Grant Letter and these Grant Conditions, the Grantee acknowledges the following:

(a) the Plan is established voluntarily by the Company, the grant of the Performance Units under the Plan is made at the discretion of the Committee and the Plan may be modified, amended, suspended or terminated by the Company at any time;

(b) the grant of the Performance Units under the Plan is voluntary and occasional and does not create any contractual or other right to receive future grants of Performance Units, or benefits in lieu of them, even if Performance Units have been granted repeatedly in the past;

(c) all decisions with respect to future grants of Performance Units, if any, will be at the sole discretion of the Committee;

(d) the Grantee is voluntarily participating in the Plan;

(e) the Performance Units and any shares of Company Stock acquired under the Plan are extraordinary items that do not constitute compensation of any kind for services of any kind rendered to the Employer (including, as applicable, the Grantee’s employer) and which are outside the scope of the Grantee’s employment contract, if any;

(f) the Performance Units and any shares of Company Stock acquired under the Plan are not to be considered part of the Grantee’s normal or expected compensation or salary for any purpose, including, but not limited to, calculating any severance, resignation, termination, payment in lieu of notice, redundancy, end of service payments, bonuses, long-service awards, pension or retirement or welfare benefits or similar payments;

(g) the Performance Units and the shares of Company Stock subject to the award are not intended to replace any pension rights or compensation;

(h) the grant of Performance Units and the Grantee’s participation in the Plan will not be interpreted to form an employment contract or relationship with the Employer;

(i) the future value of the underlying shares of Company Stock is unknown and cannot be predicted with certainty. If the Grantee vests in the Performance Units and receives shares of Company Stock, the value of the acquired shares may increase or decrease. The Grantee understands that the Company is not responsible for any foreign exchange fluctuation between the United States Dollar and the Grantee’s local currency that may affect the value of the Performance Units or the shares of Company Stock; and

(j) the Grantee shall have no rights, claim or entitlement to compensation or damages as a result of the Grantee’s cessation of employment for any reason whatsoever, whether or not in breach of contract or local labor law, insofar as these rights, claim or entitlement arise or may arise from the Grantee’s ceasing to have rights under or be entitled to receive shares of Company Stock under or ceasing to have the opportunity to participate in the Plan as a result of such cessation or loss or diminution in value of the Performance Units or any of the shares of Company Stock acquired thereunder as a result of such cessation, and the Grantee irrevocably releases the Employer from any such rights, entitlement or claim that may arise. If, notwithstanding the foregoing, any such right or claim is found by a court of competent jurisdiction to have arisen, then the Grantee shall be deemed to have irrevocably waived the Grantee’s entitlement to pursue such rights or claim.

18. Addendum. Notwithstanding any provisions in these Grant Conditions, the Performance Units shall be subject to any special terms and conditions set forth in any Addendum to this Agreement for the Grantee’s country. Moreover, if the Grantee relocates to one of the countries included in the Addendum, the special terms and conditions for such country will apply to the Grantee, to the extent the Company determines that the application of such terms and conditions is necessary for legal or administrative reasons. The Addendum constitutes part of these Grant Conditions.

ADDENDUM

ARMSTRONG WORLD INDUSTRIES, INC.

PERFORMANCE RESTRICTED STOCK UNIT GRANT

Additional Terms and Conditions and Notifications

This Addendum includes special terms and conditions that govern the Performance Units granted to the Grantee if the Grantee resides in the countries listed herein. These terms and conditions are in addition to the terms and conditions set forth in the Grant Conditions. This Addendum may also include information regarding certain other issues of which the Grantee should be aware with respect to the Grantee’s participation in the Plan. Capitalized terms used but not defined herein shall have the meanings assigned to them in the Grant Conditions (of which this Addendum is a part) and the Plan.

Australia

(a) The Grant Letter and Grant Conditions have been prepared for the purpose of providing general information, without taking account of the Grantee’s objectives, financial situation or needs. The Grantee should, before making any decisions, consider the appropriateness of the information in the Grant Letter and Grant Conditions, and seek professional advice, having regard to the Grantee’s objectives, financial situation and needs.

(b) The Company is not licensed to provide financial product advice in Australia in relation to the Performance Units and recommends that the Grantee read the Plan, the Grant Letter and the Grant Conditions in full before making a decision to be granted Performance Units. There is no cooling-off regime in Australia that applies in respect of the grant of Performance Units.

(c) If the Grantee acquires shares of Company Stock under the Plan and offers such shares for sale to a person or entity resident in Australia, the offer may be subject to disclosure requirements under Australian law. The Grantee should obtain legal advice on disclosure obligations prior to making any such offer.

France

Language Consent. The parties acknowledge that it is their express wish that the agreements, as well as all documents, notices and legal proceedings entered into, given or instituted pursuant hereto or relating directly or indirectly hereto, be drawn up in English.

Les parties reconnaissent avoir exigé la rédaction en anglais de cette convention, ainsi que de tous documents exécutés, avis donnés et procédures judiciaries intentées, directement ou indirectement, relativement à ou suite à la présente convention.

Netherlands

The Grantee should be aware of the Dutch insider trading rules, which may impact the sale of shares of Company Stock acquired under the Performance Units. In particular, the Grantee may be prohibited from effecting certain share transactions if the Grantee has insider information regarding the Company. Below is a discussion of the applicable restrictions. The Grantee is advised to read the discussion carefully to determine whether the insider rules apply to the Grantee. If it is uncertain whether the insider rules apply, the Company recommends that the Grantee consult with his or her personal legal advisor. Please note that the Company cannot be held liable if the Grantee violates the Dutch insider rules. The Grantee is responsible for ensuring compliance with these rules.

By entering into this Agreement and participating in the Plan, the Grantee acknowledges having read and understood the notification below and acknowledges that it is his or her own responsibility to comply with the Dutch insider trading rules, as discussed herein.

PROHIBITION AGAINST INSIDER TRADING.

Dutch securities laws prohibit insider trading. Under Article 5.56 of the Dutch Financial Supervision Act, anyone who has “inside information” related to the Company is prohibited from effectuating a transaction in securities in or from the Netherlands. “Inside information” is knowledge of specific information concerning the issuer to which the securities relate that is not public and which, if published, would reasonably be expected to affect the share price, regardless of the actual effect on the price. The insider could be any employee of the Company or an affiliate in the Netherlands who has inside information as described above.

Given the broad scope of the definition of inside information, certain employees of the Company working at its Dutch affiliate may have inside information and thus, would be prohibited from effectuating a transaction in securities in the Netherlands at a time when he or she had such inside information

Impairment testing of our tangible assets occurs whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable.  In March 2012, we made the decision to permanently close a previously idled ceiling tile plant in Mobile, Alabama.As a result, we recorded accelerated depreciation of $9.3 million for machinery and equipment and a $4.6 million impairment charge for buildings in cost of goods sold.The preliminary fair values were determined by management estimates and an independent valuation based on information available at that time (considered Level 2 inputs in the fair value hierarchy).Future charges may be incurred as more data becomes available.

During the first quarter of 2011, we announced the idling of our Statesville, NC engineered wood production facility.As a result, we evaluated the impairment implications of this decision and determined no impairment charge was necessary.

Litigation And Related Matters Environmental Matters

NOTE 16. LITIGATION AND RELATED MATTERS

ENVIRONMENTAL MATTERS

Environmental Expenditures

Our manufacturing and research facilities are affected by various federal, state and local requirements relating to the discharge of materials and the protection of the environment.We make expenditures necessary for compliance with applicable environmental requirements at each of our operating facilities.These regulatory requirements continually change, therefore we cannot predict with certainty future expenditures associated with compliance with environmental requirements.

Environmental Remediation

Summary

We are actively involved in the investigation and/or remediation of environmental contamination under the Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA"), and state or international Superfund and similar type laws at several domestically- and internationally-owned, formerly owned and non-owned locations allegedly resulting from past industrial activity.In a few cases, we are one of several potentially responsible parties ("PRPs”) where we have agreed to jointly fund the required investigation and remediation, while preserving our defenses to the liability.We may also have rights of contribution or reimbursement from other parties or coverage under applicable insurance policies.

Estimates of our future liability at the environmental sites are based on evaluations of currently available facts regarding each individual site.We consider factors such as our activities associated with the site, existing technology, presently enacted laws and regulations and prior company experience in remediating contaminated sites.Although current law imposes joint and several liability on all parties at Superfund sites, our contribution to the remediation of these sites is expected to be limited by the number of other companies potentially liable for site remediation.As a result, our estimated liability reflects only our expected share.In determining the probability of contribution, we consider the solvency of other parties, whether liability is being disputed, the terms of any existing agreements and experience with similar matters, and the effect of our Chapter 11 reorganization upon the validity of the claim.

Specific Material Events

In August 2010, we entered into a Consent Order with the Oregon Department of Environmental Quality (“ODEQ”), along with Kaiser Gypsum Company, Inc. (“Kaiser”), and Owens Corning Sales LLC (“OC”), with respect to our St. Helens, Oregon ceilings facility, which was previously owned by Kaiser and then OC.The Consent Order, which replaces a previous order of the ODEQ requiring us to investigate and remediate hazardous substances present at the facility, requires that we and Kaiser complete a remedial investigation and feasibility study (“RI/FS”) on the portion of the site owned by us.The Consent Order further requires us, Kaiser and OC to conduct an RI/FS in the adjacent Scappoose Bay.Our current estimate of our future liability at the site relates to the investigation work required by the Consent Order and to the currently projected cost of possible remedies for certain portions of the site.However, neither the RI/FS for the portion of the property owned by us nor the Scappoose Bay is complete.At this time, we have determined that it is probable that additional corrective action for the portion of the property owned by us will be required.Such corrective action could result in additional costs greater than currently estimated and, consequently, those costs may be material.At this time, it is not possible to reasonably estimate the total costs that we may ultimately incur with respect to the Scappoose Bay, although such amounts may be material.

Costs and responsibilities for the RI/FS for certain portions of the St. Helens property owned by us continue to be shared with Kaiser pursuant to an agreement with Kaiser.Limited contributions are also being made by ODEQ pursuant to its settlement with OC for OC’s liabilities for the property.Contemporaneously with the execution of the Consent Order, we, Kaiser and OC also entered into a cost allocation agreement for the investigation and possible remediation of the Scappoose Bay.

The U.S. Environmental Protection Agency (“EPA”) has listed two landfills located on a portion of our ceilings facility in Macon, Georgia, along with the former Macon Naval Ordnance Plant landfill adjacent to our property, and portions of Rocky Creek (collectively the “Macon Site”) as a Superfund site on the National Priorities List due to the presence of contaminants, most notably PCBs.In September 2010, we entered into an Administrative Order on Consent for a Removal Action with the EPA to investigate PCB contamination in one of the landfills on our property that is a portion of the Superfund Site.Our current estimate of future liability includes costs for investigative work that we agreed to perform under the EPA order.We will ultimately incur expenses for closure or some form of remedial action with respect to the landfill.While those amounts are not estimable at this time, they may be material.Additionally, it is probable that we will incur field investigation, engineering and oversight costs associated with an RI/FS with respect to the remainder of the Superfund site, including Rocky Creek.We, along with other parties, may also ultimately incur costs in remedying contamination discovered during the RI/FS.At this time, it is not possible to reasonably estimate the amounts we may ultimately incur with respect to those activities, although such amounts may be material.

Summary of Financial Position

Liabilities of $ 7.3 million at March 31, 2012 and December 31, 2011 were recorded for potential environmental liabilities, on a global basis, that we consider probable and for which a reasonable estimate of the probable liability could be made.Where existing data is sufficient to estimate the liability, that estimate has been used; where only a range of probable liabilities is available and no amount within that range is more likely than any other, the lower end of the range has been used.As assessments and remediation activities progress at each site, these liabilities are reviewed to reflect new information as it becomes available.These liabilities are undiscounted.

The estimated liabilities above do not take into account any claims for recoveries from insurance or third parties.It is our policy to record probable recoveries that are either available through settlement or anticipated to be recovered through negotiation or litigation as assets in the Condensed Consolidated Balance Sheets.No amounts were recorded for probable recoveries at March 31, 2012 or December 31, 2011.

Actual costs to be incurred at identified sites may vary from our estimates.Based on our current knowledge of the identified sites, it is not possible to reasonably estimate future costs which may exceed amounts already recognized.

ANTIDUMPING AND COUNTERVAILING DUTY PETITION

In October 2010, a coalition of U.S. producers of multilayered wood flooring (not including Armstrong) filed antidumping (“AD”) and countervailing duty (“CVD”) petitions regarding multilayered hardwood flooring from China.  The AD petition requested that the Department of Commerce impose duties of up to 269% on imports of multilayered hardwood flooring, which it claimed were needed to offset unfair pricing from Chinese imports that injure the U.S. industry.  The CVD petition requested an unspecified level of duties be imposed on importers to offset alleged unfair subsidies provided by the Chinese government.

We produce multilayered wood flooring domestically and import multilayered wood flooring from suppliers in China.  We also have a plant in China that manufactures multilayered wood flooring for export to the U.S.  We are specifically mentioned in the AD and CVD petitions as an importer.  Under the U.S. AD and CVD laws, a U.S. importer may be responsible for the payment of any antidumping and countervailing duties.

On October 12, 2011, the Department of Commerce announced its final determination for both CVD and AD investigations. The final rates are 1.5% (CVD) and 3.31% (AD). These rates will be retroactive to the dates of the preliminary determinations, and will be credited against the preliminary rates. Based on the final rates announced by the Department of Commerce, this matter is not expected to have a material adverse effect on our results of operations, financial position or cash flows.

A number of appeals have been filed by several parties challenging various aspects of the determinations by both the Department of Commerce and the International Trade Commission. Armstrong will participate in a number of these, and expects some or all of the appeals to be consolidated.

OTHER CLAIMS

We are involved in various lawsuits, claims, investigations and other legal matters from time to time that arise in the ordinary course of conducting business, including matters involving our products, intellectual property, relationships with suppliers, distributors, relationships with competitors, employees and other matters.While complete assurance cannot be given to the outcome of these proceedings, we do not currently believe that any of these matters, individually or in the aggregate, will have a material adverse effect on our financial condition, liquidity or results of operations.

Business And Basis Of Presentation [Abstract]

Business And Basis Of Presentation

NOTE 1.BUSINESS AND BASIS OF PRESENTATION

Armstrong World Industries, Inc. (“AWI”) is a Pennsylvania corporation incorporated in 1891. When we refer to "we", "our" and "us" in these notes, we are referring to AWI and its subsidiaries.We use the term “AWI” when we are referring solely to Armstrong World Industries, Inc.

In December 2000, AWI filed a voluntary petition for relief (the “Filing”) under Chapter 11 of the U.S. Bankruptcy Code (the “Bankruptcy Code”) in the United States Bankruptcy Court for the District of Delaware (the “Bankruptcy Court”) in order to use the court-supervised reorganization process to achieve a resolution of AWI’s asbestos-related liability.On October 2, 2006, AWI’s court-approved plan of reorganization (“POR”) became effective and AWI emerged from Chapter 11.All claims in AWI’s Chapter 11 case have been resolved and closed.

On October 2, 2006, the Armstrong World Industries, Inc. Asbestos Personal Injury Settlement Trust (“Asbestos PI Trust”) was created to address AWI’s personal injury (including wrongful death) asbestos-related liability.All present and future asbestos-related personal injury claims against AWI, including contribution claims of co-defendants but excluding certain foreign claims against subsidiaries, arising directly or indirectly out of AWI’s pre-Filing use of, or other activities involving, asbestos are channeled to the Asbestos PI Trust.

In August 2009, Armor TPG Holdings LLC (“TPG”) and the Asbestos PI Trust entered into agreements whereby TPG purchased 7,000,000 shares of AWI common stock from the Asbestos PI Trust and acquired an economic interest in an additional 1,039,777 shares from the Asbestos PI Trust. The Asbestos PI Trust and TPG together hold more than 60% of AWI’s outstanding shares and have entered into a shareholders’ agreement, pursuant to which the Asbestos PI Trust and TPG have agreed to vote their shares together on certain matters.

The accounting policies used in preparing the Condensed Consolidated Financial Statements in this Form 10-Q are the same as those used in preparing the Consolidated Financial Statements for the year ended December 31, 2011.These statements should therefore be read in conjunction with the Consolidated Financial Statements and notes that are included in the Form 10-K for the fiscal year ended December 31, 2011.In the opinion of management, all adjustments of a normal recurring nature have been included to provide a fair statement of the results for the reporting periods presented.Quarterly results are not necessarily indicative of annual earnings, primarily due to the different level of sales in each quarter of the year and the possibility of changes in general economic conditions.

Certain amounts in the prior year’s Condensed Consolidated Financial Statements have been recast to conform to the 2012 presentation.

These Condensed Consolidated Financial Statements are prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”).The statements include management estimates and judgments, where appropriate.Management utilizes estimates to record many items including certain asset values, allowances for bad debts, inventory obsolescence and lower of cost or market charges, warranty, workers’ compensation, general liability and environmental claims and income taxes.When preparing an estimate, management determines the amount based upon the consideration of relevant information.Management may confer with outside parties, including outside counsel.Actual results may differ from these estimates.

Operating results for the first quarters of 2012 and 2011 included in this report are unaudited.However, these Condensed Consolidated Financial Statements have been reviewed by an independent registered public accounting firm in accordance with standards of the Public Company Accounting Oversight Board (United States) for a limited review of interim financial information.

In June 2011, the FASB issued new guidance that is now part of ASC 220: “Presentation of Comprehensive Income”.The new guidance requires companies to present the components of net income and other comprehensive income either as one continuous statement or as two consecutive statements.It eliminates the option to present components of other comprehensive income as part of the statement of changes in stockholder’s equity.The standard does not change the items which must be reported in other comprehensive income.These provisions are to be applied retrospectively and were effective for us as of January 1, 2012.There was no impact on our financial condition, results of operations or cash flows.

Debt

NOTE 11.DEBT

On March 22, 2012, we amended our $1.05 billion senior credit facility arranged by Merrill Lynch, Pierce, Fenner & Smith, Inc., J.P. Morgan Securities, Inc. and Barclays Capital. We added $250 million to our existing Term Loan B facility. The amended $1.3 billion facility is made up of a $250 million revolving credit facility (with a $150 million sublimit for letters of credit), a $250 million Term Loan A and an $800 million Term Loan B.The facility is secured by U.S. personal property, the capital stock of material U.S. subsidiaries, and a pledge of 65% of the stock of our material first tier foreign subsidiaries. The only significant change to existing terms, conditions and covenants related to the consolidated leverage ratio covenant. Under the revised covenant, threshold ratios are as follow: 4.5 to1.0 through December 31, 2013, 4.0 to 1.0 through March 31, 2015, and 3.75 to 1.0 thereafter. During the first quarter of 2012, we were in compliance with all covenants of the previous and amended credit agreements.

In connection with the additional $250 million Term Loan B borrowings, we paid $7.6 million for bank, legal and other fees.This amount was capitalized and is being amortized into interest expense over the life of the loan.

Special Cash Dividend And Stock Option Adjustments [Abstract]

Special Cash Dividend And Stock Option Adjustments

NOTE 17.SPECIAL CASH DIVIDEND AND STOCK OPTION ADJUSTMENTS

On March 23, 2012, our Board of Directors declared a special cash dividend in the amount of $8.55 per share, or $508.3 million in the aggregate, of which $503.0 million was paid on April 10, 2012 to the shareholders of record as of April 3, 2012.The unpaid portion of the dividend relates to unvested employee shares and is reflected in current liabilities ($1.8 million) and other long term liabilities ($3.5 million) and will be paid when the underlying employee shares vest.The dividend was funded in part by existing cash and in part by the proceeds of additional debt issued under our Term Loan B.The dividend was recorded as a reduction of retained earnings to the extent that retained earnings were available at the dividend declaration date.Dividends in excess of retained earnings were recorded as a reduction of capital in excess of par value.

Under the terms of the 2011 Long Term Incentive Plan (“the Plan”), the Management Development and Compensation Committee of our Board of Directors is required to make equitable adjustments to stock option grants if there is a change in our capital structure.The special cash dividend qualified as a change to our capital structure under the terms of the Plan.We used the Black-Scholes option pricing model to determine the fair value of the awards before and after the special cash dividend, using consistent assumptions for the risk free rate of return, expected term, expected volatility and expected dividend yield.The stock prices used in the before and after calculations were $57.38 (the New York Stock Exchange Volume Weighted Average Price (“NYSE VWAP”) on March 29, 2012, the day before the ex-dividend date) and $49.21 (NYSE VWAP on March 30, 2012, the ex-dividend date), respectively.For all option grants, the fair value of the award before and after the dividend remained the same.Therefore there was no incremental cost recognized in our financial statements due to these award modifications.

The following changes were made to the options outstanding as a result of this change:

	Pre-Dividend Grant Terms		Post-Dividend Grant Terms

NOTE 13. FINANCIAL INSTRUMENTS

We do not hold or issue financial instruments for trading purposes.The estimated fair values of our financial instruments are as follows:

	March 31, 2012		December 31, 2011
	Carrying amount	Estimated fair value	Carrying amount	Estimated fair value
Assets/(Liabilities), net:
Total debt, including current portion	$ (1,092.1)	$ (1,092.1)	$ (843.0)	$ (835.2)
Foreign currency contract obligations	(1.0)	(1.0)	1.1	1.1
Natural gas contracts	(10.2)	(10.2)	(9.3)	(9.3)
Interest rate swap contracts	(15.5)	(15.5)	(14.0)	(14.0)

The carrying amounts of cash and cash equivalents of $683.3 million at March 31, 2012 (made up of bank deposits), receivables, accounts payable and accrued expenses, short-term debt and current installments of long-term debt approximate fair value because of the short-term maturity of these instruments.The fair value estimates of long-term debt were based upon quotes from a major financial institution of recently observed trading levels of our Term Loan B debt.The fair value estimates of foreign currency contract obligations are estimated from market quotes provided by a well recognized national market data provider.The fair value estimates of natural gas contracts are estimated using internal valuation models with verification by obtaining quotes from major financial institutions.For natural gas swap transactions, fair value is calculated using NYMEX market quotes provided by a well recognized national market data provider.For natural gas option based strategies, fair value is calculated using an industry standard Black-Scholes model with market based inputs, including but not limited to, underlying asset price, strike price, implied volatility, discounted risk free rate and time to expiration, provided by a well recognized national market data provider.The fair value estimates for interest rate swap contracts are estimated by obtaining quotes from major financial institutions with verification by internal valuation models.

As of March 31, 2012 and December 31, 2011, we also had $0.2 million and $1.5 million,respectively, of restricted cash that is held by a trustee related to the construction of our Millwood, West Virginia mineral wool plant.The trustee has invested the cash in money market investments.The carrying value on our balance sheet approximates the fair value because of the short-term maturity of the instruments. We anticipate the release of these funds during the second quarter of 2012.

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date.U.S. GAAP establishes a three-level fair value hierarchy that prioritizes the inputs used to measure fair value.The three levels of inputs used to measure fair value are as follows:

Level 1 — Quoted prices in active markets for identical assets or liabilities.

Level 2 — Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.

Assets and liabilities are summarized below:

	March 31, 2012		December 31, 2011
	Fair value based on		Fair value based on
	Quoted, active markets Level 1	Other observable inputs Level 2	Quoted, active markets Level 1	Other observable inputs Level 2
Assets/(Liabilities), net:
Total debt, including current portion	$ (794.5)	$ (297.6)	$ (545.9)	$ (289.3)
Foreign currency contract obligations	$ (1.0)	-	$ 1.1	-
Natural gas contracts	-	$ (10.2)	-	$ (9.3)
Interest rate swap contracts	-	(15.5)	-	(14.0)

We do not have any financial assets or liabilities that are valued using Level 3 (unobservable) inputs.

Restructuring Actions

NOTE 9. RESTRUCTURING ACTIONS

During the third quarter of 2010, management made several significant decisions to address our cost structure.Given the materiality to our financial statements and impact to our operations, we decided to classify charges related to these actions as restructuring charges.The following table summarizes the restructuring charges recorded in the first quarters of 2012 and 2011:

	Three Months Ended March 31,
Action Title	2012	2011	Segment
Floor Products Europe	$ 0.2	$ 3.1	Resilient Flooring
North America SG&A	-	0.4	Unallocated Corporate, Resilient Flooring
Beaver Falls plant	-	1.6	Building Products
Other initiatives	-	(0.2)	Wood Flooring
Total	$ 0.2	$ 4.9

Floor Products Europe:In the third quarter of 2010, we announced our intent to focus our European flooring strategy on products and regions in which we believe we can be a market leader, and to streamline our product range and sales organization accordingly.During the fourth quarter of 2010, we withdrew from the residential market and, as a result, we sold our Teesside, UK manufacturing facility.In addition, during the second quarter of 2011, we ceased production at our heterogeneous vinyl flooring plant in Holmsund, Sweden.

In addition to the restructuring costs reflected in the above table, in the first quarter of 2011, we recorded $2.1 million of other related costs in cost of goods sold ($1.7 million) and SG&A expense ($0.4 million).Other related costs are primarily related to inventory obsolescence, accelerated depreciation and plant closure costs.

Through March 31, 2012, we have incurred expense of $30.1 million related to this initiative.We do not expect to incur further material restructuring costs related to this initiative.

North America SG&A:We are committed to augmenting margin expansion through the aggressive adoption of projects to standardize, simplify or eliminate SG&A activities.As a result, in the third quarter of 2010, we began to restructure our North American SG&A operations.The first quarter 2011 restructuring expense related to this initiative was recorded in the Unallocated Corporate ($0.3 million) and Resilient Flooring ($0.1 million) segments.

Through March 31, 2012, we have incurred restructuring expense of $7.2 million related to this initiative.In total, we expect to incur restructuring expenses of up to $8 million related to this initiative through 2012 as we further streamline North American SG&A functions.

Beaver Falls Plant:Production at the Beaver Falls, Pennsylvania facility ended March 31, 2011, and production requirements have been transitioned to other facilities.The decision to close the plant was driven by the location and layout of the plant, technology limitations and the continued limited demand for the products we made at the plant.

In addition to the restructuring costs reflected in the table above, we also recorded $4.7 million of accelerated depreciation in the first quarter of 2011 in cost of goods sold.

Through March 31, 2012, we have incurred expense of $25.1 million related to this initiative.We do not expect to incur additional costs in the future as the plant was sold in 2011.The sale resulted in a net gain of $0.7 million which was recorded in SG&A in the third quarter of 2011.

The following table summarizes activity in the restructuring accruals.

	Severance and Related Costs
	Floor Products Europe	North America SG&A	Beaver Falls Plant	Total
December 31, 2011	$ 3.2	$ 0.5	$ 0.1	$ 3.8
Net charges	0.2	-	-	0.2
Cash payments	(1.0)	(0.4)	-	(1.4)
Other	0.1	-	-	0.1
March 31, 2012	$ 2.5	$ 0.1	$ 0.1	$ 2.7

The amounts in “Other” are related to the effects of foreign currency translation.

Most of the accrual balance as of March 31, 2012 is expected to be paid by June 30, 2012.

NOTE 8. SEVERANCES AND RELATED COSTS

See Note 9 to the Condensed Consolidated Financial Statements for a discussion of severance charges associated with restructuring actions.

In the first quarter of 2011, we recorded $3.0 million in cost of goods sold for severance and related costs to reflect position eliminations in our European Resilient Flooring business as a result of improved manufacturing productivity.In addition, we recorded $0.5 million in SG&A expense for severance and related costs to reflect the separation costs for our former Senior Vice President, General Counsel and Secretary.

Income Tax Expense [Abstract]

Income Tax Expense

NOTE 10.INCOME TAX EXPENSE

The effective tax rate for the first quarter 2012 was 41.7% which was lower than the 64.1% effective tax rate in the comparable period in 2011, primarily due to the favorable tax impact from our mix of income from international operations.Additionally, the effective tax rate was higher in the first quarter of 2011 since we increased state valuation allowances based on our projected ability to utilize the deferred tax assets to offset future taxable income.

We do not expect to record any material changes during 2012 to unrecognized tax benefits that were claimed on tax returns covering tax years ending on or before December 31, 2011.

Derivative Financial Instruments [Abstract]

Derivative Financial Instruments

NOTE 14.DERIVATIVE FINANCIAL INSTRUMENTS

We are exposed to market risk from changes in foreign exchange rates, interest rates and commodity prices that could impact our results of operations and financial condition.We use forward swaps and option contracts to hedge certain of these exposures.Exposure to individual counterparties is controlled and derivative financial instruments are entered into with a diversified group of major financial institutions.Forward swaps and option contracts are entered into for periods consistent with underlying exposure and do not constitute positions independent of those exposures.At inception, hedges that we designate as hedging instruments are formally documented as either (1) a hedge of a forecasted transaction or “cash flow” hedge, or (2) a hedge of the fair value of a recognized liability or asset or “fair value” hedge.We also formally assess both at inception and at least quarterly thereafter, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in either the fair value or cash flows of the hedged item.If it is determined that a derivative ceases to be a highly effective hedge, or if the anticipated transaction is no longer probable of occurring, we discontinue hedge accounting, and any future mark to market adjustments are recognized in earnings.We use derivative financial instruments as risk management tools and not for speculative trading purposes.

Counterparty Risk

We only enter into derivative transactions with established counterparties having a credit rating of BBB or better.We monitor counterparty credit default swap levels and credit ratings on a regular basis.All of our derivative transactions with counterparties are governed by master International Swap and Derivatives Association agreements (“ISDAs”) with netting arrangements.These agreements can limit our exposure in situations where we have gain and loss positions outstanding with a single counterparty.We generally do not post nor do we receive cash collateral with any counterparty for our derivative transactions.As of March 31, 2012, we had no cash collateral posted or received for any of our derivative transactions.These ISDAs do not have any credit contingent features; however, a default under our bank credit facility would trigger a default under these agreements.Exposure to individual counterparties is controlled, and thus we consider the risk of counterparty default to be negligible.

Commodity Price Risk

We purchase natural gas for use in the manufacture of ceiling tiles and other products, and to heat many of our facilities.As a result, we are exposed to fluctuations in the price of natural gas.We have a policy to reduce cost volatility for North American natural gas purchases by purchasing natural gas forward contracts and swaps, purchased call options, and zero-cost collars up to 24 months forward to reduce our overall exposure to natural gas price movements.There is a high correlation between the hedged item and the hedged instrument.The gains and losses on these transactions offset gains and losses on the transactions being hedged.These instruments are designated as cash flow hedges.At March 31, 2012 and December 31, 2011, the notional amount of these hedges was $41.2 million and $47.2 million, respectively.The mark-to-market gain or loss on qualifying hedges is included in other comprehensive income to the extent effective, and reclassified into cost of goods sold in the period during which the underlying gas is consumed.The mark-to-market gains or losses on ineffective portions of hedges are recognized in cost of goods sold immediately.The earnings impact of the ineffective portion of these hedges was not material for the first quarter of 2012 and 2011.The contracts are based on forecasted usage of natural gas measured in mmBtu’s.

Currency Rate Risk – Sales and Purchases

We manufacture and sell our products in a number of countries throughout the world and, as a result, we are exposed to movements in foreign currency exchange rates.To a large extent, our global manufacturing and sales provide a natural hedge of foreign currency exchange rate movement, as foreign currency expenses generally offset foreign currency revenues.We manage our cash flow exposures on a net basis and use derivatives to hedge the majority of our unmatched foreign currency cash inflows and outflows.As of March 31, 2012, our major foreign currency exposures are to the Canadian dollar, the Euro, and the Australian dollar.

We use foreign currency forward exchange contracts to reduce our exposure to the risk that the eventual net cash inflows and outflows resulting from the sale of products to foreign customers and purchases from foreign suppliers will be adversely affected by changes in exchange rates.These derivative instruments are used for forecasted transactions and are classified as cash flow hedges.Cash flow hedges are executed quarterly, generally up to 15 months forward, and allow us to further reduce our overall exposure to exchange rate movements, since gains and losses on these contracts offset gains and losses on the transactions being hedged.The notional amount of these hedges was $145.0 million and $128.3 million at March 31, 2012 and December 31, 2011, respectively.Gains and losses on these instruments are recorded in other comprehensive income, to the extent effective, until the underlying transaction is recognized in earnings.The earnings impact of the ineffective portion of these hedges was not material for the first quarter of 2012 and 2011.

Currency Rate Risk - Intercompany Loans and Dividends

We also use foreign currency forward exchange contracts to hedge exposures created by cross-currency intercompany loans and dividends.The translation adjustments related to these loans are recorded in other non-operating income or expense.The offsetting gains or losses on the related derivative contracts are also recorded in other non-operating income or expense.These contracts are decreased or increased as repayments are made or additional intercompany loans are extended or adjusted for intercompany dividend activity as necessary.The notional amount of these hedges was $22.0 million and $21.8 million at March 31, 2012 and December 31, 2011, respectively.

Interest Rate Risk

We utilize interest rate swaps to minimize the fluctuations in earnings caused by interest rate volatility. Interest expense on variable-rate liabilities increases or decreases as a result of interest rate fluctuations. On March 31, 2011 we entered into two interest rate swaps, on our Term Loan A and Term Loan B, with notional amounts of $100 million and $200 million, respectively, which mature in November 2015. Under the terms of the Term Loan A swap, we receive 3-month LIBOR and pay a fixed rate over the hedged period. Under the terms of the Term Loan B swap, we receive the greater of 3-month LIBOR or the 1% LIBOR Floor and pay a fixed rate over the hedged period. On March 27, 2012 we entered into an additional interest rate swap agreement with a notional amount of $250 million, maturing in November 2018, where we pay a fixed rate of 1.9275% over the hedged period. We also entered into a forward starting interest rate swap of $200 million from November 2015 to March 2018, where we pay a fixed rate of 2.810% over the hedged period. These swaps are designated as cash flow hedges against changes in LIBOR for a portion of our variable rate debt.
