Statement on Forward-Looking Information

Our disclosures in this report and in our other public documents and comments contain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities and Exchange Act of 1934, as amended. 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 Securities and Exchange Commission (“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 statement is provided as permitted by the Private Securities Litigation Reform Act of 1995.

Notes to Condensed Consolidated Financial Statements (Unaudited)
(dollar amounts in millions)

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. Also filing under Chapter 11 were two of AWI’s wholly-owned subsidiaries, Nitram Liquidators, Inc. (“Nitram”) and Desseaux Corporation of North America, Inc. (“Desseaux”). On October 2, 2006, AWI’s court-approved Plan of Reorganization (“POR”) became effective and AWI emerged from Chapter 11. See Note 1 to our 2010 annual report on Form 10-K for more information on the Chapter 11 Case.

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, 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, 2010. These statements should therefore be read in conjunction with the Consolidated Financial Statements and notes that are included in our Form 10-K for the fiscal year ended December 31, 2010. 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 2011 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 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 and consultants. Actual results may differ from these estimates.

In September 2011, the Financial Accounting Standards Board (“FASB”) issued new guidance that is now part of Accounting Standards Codification (“ASC”) 350:“Intangibles — Goodwill and Other". The new guidance will permit an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. Because the objective of this new guidance is to simplify how entities test for goodwill impairment, it will not have a material impact on our financial statements.

Armstrong World Industries, Inc., and Subsidiaries
Notes to Condensed Consolidated Financial Statements (Unaudited)
(dollar amounts in millions)

In June 2011, the FASB issued new guidance that is now part of ASC 220: “Presentation of Comprehensive Income”.The new guidance will require 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 will be effective for us as of January 1, 2012. Because this guidance impacts presentation only, it will have no effect on our financial condition, results of operations or cash flows.

In January 2010, the FASB issued new guidance that is now part of ASC 820, “Fair Value Measurements and Disclosures”. The new guidance requires disclosures of the amounts of assets and liabilities transferred into and out of Levels 1 and 2, along with a description of the reasons for the transfers. The new guidance also requires additional disclosures related to activity presented for Level 3 measurements. These provisions were effective for us as of January 1, 2010 except for the additional disclosures related to activities for Level 3 measurements which were effective for us as of January 1, 2011. There was no impact on our financial statements from the adoption of this guidance.

In March 2010, the FASB issued new guidance that is now part of ASC 815, “Derivatives and Hedging”. The new guidance clarifies the scope exception for embedded credit related derivatives. The provisions were effective for us as of January 1, 2011. There was no impact on our financial statements from the adoption of this guidance.

In July 2010, the FASB issued new guidance that is now part of ASC 310,“Receivables". The new guidance increases the disclosure requirements regarding the credit quality of financing receivables and the allowance for credit losses. Some of the provisions were effective for us as of December 31, 2010 and others were effective January 1, 2011. There was no impact on our financial statements from the adoption of this guidance.

Operating results for the third quarter and first nine months of 2011 and the corresponding periods of 2010 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.

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

During the third quarter of 2011, we recorded an asset impairment charge of $2.2 million in selling, general and administrative (“SG&A”) expense for a European Resilient Flooring office building. The fair value was determined by management estimates of market prices based upon information available, including offers received from potential buyers of the property (considered Level 3 inputs in the fair value hierarchy as described in Note 15 to the Condensed Consolidated Financial Statements).

During the first quarter of 2010, we decided to exit our flight operations. As a result, we recorded a $3.1 million impairment charge in SG&A expense. The fair values were determined by management estimates of market prices based upon information available at that time. This data included sales of similar equipment and historical appraisal information (considered Level 3 inputs in the fair value hierarchy).

Additionally, during the first quarter of 2010, we announced that one of our European metal ceilings manufacturing facilities would be shutdown in the second quarter of 2010, which prompted us to perform an impairment test for this asset group. The carrying amount of the tangible assets was determined to be recoverable as the projected undiscounted cash flows exceeded the carrying value. We sold the facility in the third quarter of 2010.

(dollar amounts in millions)

During the second quarter of 2010, we received additional information regarding the estimated fair value for our flight operations assets. As a result, we recorded an additional $3.0 million impairment charge in SG&A expense in the second quarter of 2010. The fair values were determined by management estimates and an independent valuation. The valuation information included sales of similar equipment and estimates of market prices (considered Level 2 inputs in the fair value hierarchy) for these assets. We sold the corporate aircraft in the fourth quarter of 2010.

We also recorded an asset impairment charge of $2.1 million in SG&A expense in the second quarter of 2010 for a European Resilient Flooring warehouse facility due to the decline in the commercial property sector. The fair value was determined by management estimates of market prices available at that time. This data included sales and leases of comparable properties within similar real estate markets (considered Level 3 inputs in the fair value hierarchy). We sold the warehouse on January 1, 2011.

During the third quarter of 2010, we decided to close an Americas ceiling plant, one of our previously idled Wood Flooring plants, portions of another previously idled Wood Flooring plant, and an Americas Resilient Flooring facility. These facilities were shut down either in the fourth quarter of 2010, or in the first quarter of 2011. In addition to these domestic facilities, we announced our intention to exit the residential flooring business in Europe. We performed an impairment analysis for these facilities and, in each case, the carrying amount of the tangible assets was determined to be recoverable, as the projected undiscounted cash flows, or estimated fair value of the assets, exceeded the carrying value.

NOTE 3. ACQUISITIONS

As of December 31, 2009, we owned 80% of our Shanghai ceiling operations. During the fourth quarter of 2009, we made deposits of $3.3 million to initiate the purchase of the remaining 20% interest. During the first quarter of 2010, we completed the acquisition with additional cash payments of $7.8 million. We recorded the difference between the purchase price and the net book value of the net equity acquired within capital in excess of par value.

NOTE 10. SEVERANCES AND RELATED COSTS

See Note 11 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.

In the first quarter of 2010, we recorded $11.2 million in SG&A expense for severance and related costs to reflect the separation costs for our former Chairman and Chief Executive Officer. In accordance with the separation agreement, payment was made in the third quarter of 2010.

During the first quarter of 2010, we announced the shutdown of finished goods production at two Wood Flooring plants and the restarting of certain operations at a previously idled Wood Flooring plant. We

13

Armstrong World Industries, Inc., and Subsidiaries
Notes to Condensed Consolidated Financial Statements (Unaudited)
(dollar amounts in millions)

recorded $2.8 million of severance and related costs in the first quarter of 2010 for approximately 425 employees affected by these actions. The charges were recorded in cost of goods sold.

In the second quarter of 2010, we recorded $4.1 million of severance and related costs for employees impacted by the closure of a European metal ceilings manufacturing facility and by the elimination of 75 other manufacturing and SG&A positions around the world.

NOTE 11. 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 third quarters and first nine months of 2011 and 2010:

	Three Months		Three Months		Nine Months			Nine Months
	Ended		Ended		Ended			Ended
	September 30,		September 30,		September 30,			September 30,
Action Title	2011		2010		2011			2010		Segment
Floor Products Europe	$	0.7	$	11.9	$	6.0		$	11.9	Resilient Flooring
Beaver Falls plant		—		1.0		1.3			1.0	Building Products
North America SG&A		—		1.0		0.9			1.0	Unallocated Corporate, Resilient Flooring, Building Products
Other initiatives		—		1.1		(0.2	)		1.1
Total	$	0.7	$	15.0	$	8.0		$	15.0

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, we ceased production at our heterogeneous vinyl flooring plant in Holmsund, Sweden, during the second quarter of 2011.

In addition to the restructuring costs reflected in the above table, we recorded $1.4 million in the third quarter and $6.2 million in the first nine months of 2011 of other related costs in cost of goods sold ($0.6 million in the third quarter and $4.7 million in the first nine months) and SG&A expense ($0.8 million in the third quarter and $1.5 million in the first nine months). We also recorded other related costs of $2.6 million in cost of goods sold and $0.6 million in SG&A in the third quarter and first nine months of 2010. Other related costs are primarily related to inventory and samples obsolescence, accelerated depreciation and plant closure costs.

Through September 30, 2011, we have incurred expense of $29.0 million related to this initiative. In total, we expect to incur expenses of up to $30 million for these actions through 2011. The remaining expenses primarily will include severance benefits.

Beaver Falls Plant: In the third quarter of 2010, we announced that the Beaver Falls, Pennsylvania, plant was scheduled to close in 2011. Production at the 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.

Armstrong World Industries, Inc., and Subsidiaries

(dollar amounts in millions)

In addition to the restructuring costs reflected in the table above, we also recorded $0.1 million in the third quarter and $6.6 million in the first nine months of 2011 of accelerated depreciation and $1.7 million in the third quarter and $4.5 million in the first nine months of 2011 of closure-related costs. We also recorded $4.8 million of accelerated depreciation in cost of goods sold in the third quarter and first nine months of 2010.

Through September 30, 2011, we have incurred expense of $24.7 million related to this initiative. We do not expect to incur additional costs in the future as the plant was sold in the third quarter of 2011. The sale resulted in a net gain of $0.7 million which was recorded in SG&A.

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 nine months of 2011 restructuring expense related to this initiative was recorded in the Unallocated Corporate ($0.6 million), Resilient Flooring ($0.2 million) and Building Products ($0.1 million) segments.

Through September 30, 2011 we have incurred restructuring expense of $6.7 million related to this initiative. In total, we expect to incur restructuring expenses of up to $8 million through 2012 as we further streamline SG&A functions.

The following table summarizes activity in the restructuring accruals.

	Severance and Related Costs
	Floor						North
	Products			Beaver Falls			America			Other

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

Most of the accrual balance as of September 30, 2011 is expected to be paid by June 30, 2012.

NOTE 12. INCOME TAX EXPENSE

Effective tax rate		36.8	%		45.5	%		42.9	%		69.4	%

The effective tax rate for the third quarter of 2011 was lower than the comparable period of 2010, primarily due to the reduction in 2011 of unbenefited foreign losses. Additionally, in the third quarter of 2010, there was a partial release of state valuation allowances based on our projected ability to utilize the deferred tax assets to offset future taxable income.

The effective tax rate for the first nine months of 2011 was lower than the first nine months of 2010 due to the enactment of the federal healthcare reform legislation in March 2010.

We do not expect to record any material changes during 2011 to unrecognized tax benefits that were claimed on tax returns covering tax years ending on or before December 31, 2010.

NOTE 13. DEBT

On March 10, 2011, 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. The amended terms of Term Loan B resulted in a lower LIBOR floor (1.0% vs. 1.5%) and interest rate spread (3.0% vs. 3.5%). We also extended its maturity from May 2017 to March 2018. All other terms, conditions and covenants were unchanged from the November 23, 2010 agreement. In connection with the amendment to Term Loan B, we paid a $5.5 million prepayment premium (representing one percent of the principal amount of Term Loan B). The premium was capitalized and is being amortized into interest expense over the life of the loan. Additionally, we paid approximately $1.6 million of fees to third parties (banks, attorneys, etc.), which is reflected in interest expense.

During the first nine months of 2011, we were in compliance with all covenants of the previous and amended credit agreements. Our 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 a $550 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.

NOTE 15. FINANCIAL INSTRUMENTS

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

	September 30, 2011						December 31, 2010
	Carrying			Estimated			Carrying			Estimated
	amount			Fair Value			amount			Fair Value
Liabilities, net:
Total debt, including current portion	$	(843.5	)	$	(823.8	)	$	(874.9	)	$	(882.8	)
Foreign currency contract obligations		—			—			(7.0	)		(7.0	)
Natural gas contracts		(5.2	)		(5.2	)		(5.5	)		(5.5	)
Interest rate swap contracts		(14.2	)		(14.2	)		—			—

The carrying amounts of cash and cash equivalents of $376.9 million at September 30, 2011 (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 swap transactions, fair value is calculated using NYMEX market quotes provided by a well recognized national market data provider. For 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 September 30, 2011, we also have $21.7 million of restricted cash 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.

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.

Liabilities measured at fair value on a recurring basis are summarized below:

	September 30, 2011					December 31, 2010
	Fair value based on					Fair value based on

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

NOTE 16. 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 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 A 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 September 30, 2011, 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 September 30, 2011 and December 31, 2010, the notional amount of these hedges was $52.5 million and $37.0 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

18

Armstrong World Industries, Inc., and Subsidiaries
Notes to Condensed Consolidated Financial Statements (Unaudited)
(dollar amounts in millions)

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 during the third quarter or first nine months of 2011 and 2010. 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 September 30, 2011, 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 $28.9 million and $89.9 million at September 30, 2011 and December 31, 2010, 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 during the third quarter or first nine months of 2011 and 2010.

Intercompany Loan and Dividends — We also use foreign currency forward exchange contracts to hedge exposures created by cross-currency intercompany loans and dividends. The underlying intercompany loans are classified as short-term, and 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 $11.0 million and $143.2 million at September 30, 2011 and December 31, 2010, 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. These swaps are designated as cash flow hedges to hedge against changes in LIBOR for a portion of our variable rate debt. The mark-to-market loss was $14.2 million at September 30, 2011.

NOTE 17. 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 nine months of 2011 and 2010:

NOTE 19. 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 proceedings under the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”), and similar state “Superfund” laws at several off-site locations. We have also been investigating and/or remediating environmental contamination allegedly resulting from past industrial activity at several current or former plant sites. In a few cases, we are one of several potentially responsible parties (“PRPs”) which have potential liability for the required investigation and remediation of each site. In those cases, we have agreed to jointly fund that 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 environmental liability at the Superfund sites and current or former plant 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 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 property owned by us. However, the RI/FS for the portion of the property owned by us is not yet complete. 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, we are unable to estimate with reasonable certainty the total costs that we may ultimately incur with respect to the Scappoose Bay, although such amounts may be material.

22

Armstrong World Industries, Inc., and Subsidiaries
Notes to Condensed Consolidated Financial Statements (Unaudited)
(dollar amounts in millions)

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 between Kaiser and us. 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 our future liability includes costs for investigative work that we agreed to perform under the EPA order. Additionally, 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, we are not able to estimate with reasonable certainty the amounts we may ultimately incur with respect to those activities, although such amounts may be material.

Summary of Financial Position

Liabilities of $7.8 million and $8.3 million at September 30, 2011 and December 31, 2010, respectively, 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 September 30, 2011 and December 31, 2010.

Actual costs to be incurred at identified sites may vary from our estimates. Based on our current knowledge of the identified sites, we are unable to estimate with reasonable certainty future costs which may exceed amounts already recognized.

CUSTOMS LITIGATION

In 2002, we began protesting the classification and 6% duty rate then being applied by the U.S. government on imports of our laminate flooring. After administrative denial of several of these protests, we filed a lawsuit against the United States in the U.S. Court of International Trade (New York), challenging the U.S. government’s classification and duty rate and its administrative denial of our protests. With the agreement of the U.S. Department of Justice (“DOJ”), Armstrong’s case was placed on the reserve calendar pending resolution of two test cases challenging the classification and applicable duty rate of similar laminate flooring. The test cases were decided in 2008 by the U.S. Court of International Trade, which found in favor of the U.S. government. The plaintiffs appealed to the U.S. Court of Appeals for the Federal Circuit. In September 2009 the Court of Appeals reversed the decisions of the Court of International Trade and found that the laminate flooring in the test cases should have been classified differently, and that a 3.2% duty rate should have been applied. Upon expiration of the U.S. government’s period to file notice of further appeals, we filed a stipulation request with the DOJ to stipulate that our case covered imports of laminate flooring which were like goods for which the 3.2% duty

23

Armstrong World Industries, Inc., and Subsidiaries
Notes to Condensed Consolidated Financial Statements (Unaudited)
(dollar amounts in millions)

rate likewise should apply. After review by U.S. Customs and Border Protection (“Customs”), the DOJ agreed to our proposed stipulation, which was approved by the U.S. Court of International Trade in March 2010. The stipulation provided a refund of a portion of duties paid by us on the imported laminate flooring at issue in the case, and further allows us to recover refunds on additional entries of laminate flooring which were properly protested. We have sought refunds on protested imports of laminate flooring from April 2001 through January 2007, when the classification was corrected by statute. We received refunds in 2010 of $9.7 million, $9.5 million of which was received in the first nine months of 2010. No significant refunds have been received in 2011 to date, and no significant future refunds are anticipated.

ANTIDUMPING AND COUNTERVAILING DUTY PETITION

On October 21, 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 requests that the Department of Commerce impose duties of up to 269% on imports of multilayered hardwood flooring, which it claims is needed to offset unfair pricing from Chinese imports that injure the U.S. industry. The CVD petition requests an unspecified level of duties be imposed on importers to offset alleged unfair subsidies provided by the Chinese government (such as the undervaluation of the Chinese currency, various tax benefits for foreign-invested enterprises, tax and tariff exemptions on imported equipment, and electricity being provided at artificially low rates).

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.

In March 2011, the U.S. Department of Commerce announced its preliminary determination of countervailing duties on imports of engineered wood flooring from China. The countervailing duty rate that will apply to shipments from our China plant is 2.25% of import value, which is the rate that is expected to apply to most of the companies that cooperated in the investigation. As a result, U.S. Customs will begin collecting a cash deposit (or bond) on imports of engineered wood flooring from China at these preliminary rates. This preliminary determination became effective on April 6, 2011.

Subsequent to the preliminary determination, the World Trade Organization (“WTO”) determined that the U.S. cannot impose on Chinese producers both countervailing duties and treatment of China as a non-market economy for antidumping purposes. The WTO decision echoes an earlier decision of the U.S. Court of International Trade which raised questions regarding the U.S. practice. At this time, the specific implications for pending cases such as ours remain unclear.

On May 26, 2011, the Department of Commerce announced its preliminary determination of antidumping duties on imports of engineered wood flooring from China. Initially, the duty rate on shipments from our China plant was set at 10.88% of import value. This rate was expected to apply to most of the companies that cooperated in the investigation. On June 20, 2011, the Department of Commerce modified its earlier finding and reduced the rate to 6.78%, retroactive to May 26, 2011. As a result, U.S. Customs began collecting a cash deposit (or bond) on imports of engineered wood flooring from China at these preliminary rates.

On October 12, 2011, the Department of Commerce announced its final determination for both countervailing duties (CVD) and antidumping duties (AD). 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. On November 9, 2011, the International Trade Commission is scheduled to vote as to whether imports of multilayered wood flooring from China materially injure, or threaten material injury to, the domestic industry. If the ITC finds no such injury or threatened injury, no AD or CVD order will be issued and importers will be entitled to the return of duties previously paid into escrow.

We are unable to predict the final outcome of this matter. However, 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.

OTHER CLAIMS

We are involved in various lawsuits, claims and other legal matters from time to time that arise in the ordinary course of conducting business, including claims and legal actions involving our products, intellectual property, contracts with suppliers and distributors, 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.

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 September 30, 2011, the related condensed consolidated statements of earnings for the three-month and nine-month periods ended September 30, 2011 and 2010, and the related condensed consolidated statements of cash flows and shareholders’ equity for the nine-month periods ended September 30, 2011 and 2010. 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, 2010, 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 28, 2011, 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, 2010, is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

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 third quarter of 2011, these markets experienced the following:

• According to the U.S. Census Bureau, in the third quarter of 2011 housing starts in the U.S. residential market rose 5.2% compared to the third quarter of 2010 to 0.62 million units. Housing completions in the U.S. increased 5.5% year over year in the third quarter of 2011 with approximately 0.64 million units completed. The National Association of Realtors indicated that sales of existing homes rose 17.0% year over year to 4.88 million units in the third quarter of 2011.

• According to the U.S. Census Bureau, for the value of new construction put in place, the rate of increase in the North American key commercial market, in nominal dollar terms, was 1% in the third quarter of 2011 compared to the same period in 2010. Construction activity declined 2% and 5% in the office and education segments and increased 4% in the healthcare segment in the third quarter of 2011 year over year.

• Central European markets were mixed, Western European countries generally experienced continued declines, and Eastern European markets grew.

• Overall, the Pacific Rim experienced growth, particularly in China and India, which was partially offset by declines in Australia as a result of reduced government stimulus spending.

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 third quarter 2011 total consolidated net sales by approximately $15 million and in the first nine months of 2011 by approximately $50 million, when compared to the same periods of 2010.

Year-to-date, we took the following pricing actions:

• Building Products announced price increases for ceiling tile and grid in the Americas effective February 2011, again for grid effective April 2011, and additional increases for ceiling tiles and grid effective August 2011. In Europe we announced price increases for ceiling tile effective March 2011, for grid effective April 2011, and again for ceiling tiles effective August 2011. We also announced price increases in Asia for both ceiling tile and grid effective March 2011.

• Resilient Flooring announced a price increase in Europe effective January 2011, in the Americas effective February 2011, again in the Americas effective June 2011, and again in Europe effective July 2011.

• Cabinets announced a price increase effective February 2011.

28

Management’s Discussion and Analysis of Financial Condition and Results of Operations
(dollar amounts in millions)

If raw material prices continue at, or rise from, current levels additional pricing actions may be announced.

MixEach of our businesses offers a wide assortment of products that are differentiated by style and design and by 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 affect year-to-year comparisons of net sales and operating income. We estimate that mix improvements increased our total consolidated net sales by approximately $18 million in the first nine months of 2011, and were flat for the third quarter of 2011, when compared to the same periods of 2010.

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 third quarter and first nine months of 2011, these input costs decreased operating income by approximately $15 million and $47 million, respectively, when compared to the same periods of 2010.

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 $165 million of manufacturing and SG&A costs by 2013. Toward this end, in 2010, we achieved $35 million of cost savings, and expect to deliver another $100 million in savings in 2011, and another $30- $40 million during 2012. We recorded expenses of approximately $6 million for these initiatives in the third quarter of 2011, and $31 million during the first nine months of 2011. In the second quarter of 2011, we idled one of our Wood Flooring manufacturing facilities. We will continue to evaluate the efficiency of our manufacturing footprint in the U.S. and Europe. 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 our targeted savings, there is no assurance that our net operating results in the future will improve by this amount.

Employees

As of September 30, 2011, we had approximately 9,300 active full-time and part-time employees worldwide. This compares to approximately 9,800 employees as of December 31, 2010. The decline was primarily due to headcount reductions in our U.S. and European Flooring operations and our corporate operations.

Through October 2011, we reached collective bargaining agreements with unions representing employees at four of our plants. On July 17, 2011, we declared a lockout of the unionized employees at our Building Products plant located in Marietta, Pennsylvania. The lockout, which resulted from the lack of a new ratified contract to replace the previous labor contract that expired on June 1, 2011, involves approximately 260 workers and is expected to continue until a new contract is ratified by the union.

Nine Months ended September 30
Net sales:
Americas	$	1,577.1	$	1,519.8		3.8	%
Europe		465.5		457.6		1.7	%

Total consolidated net sales	$	2,207.4	$	2,123.5		4.0	%
Operating income	$	217.6	$	111.3		95.5	%

Consolidated net sales increased in the third quarter and first nine months of 2011. Net sales grew in the third quarter on favorable foreign exchange of approximately $29 million, as volume declines were offset by improved price. Similarly, net sales grew in the first nine months on favorable foreign exchange of approximately $57 million combined with favorable price and mix, offset by volume declines.

Net sales in the Americas increased in the third quarter and first nine months of 2011. The increase in sales for the third quarter was driven by price and volume, and the increase in sales for the first nine months was driven by price and mix which overcame volume declines in the Resilient Flooring business.

Net sales in the European markets increased in the third quarter and first nine months of 2011, as volume declines were partially offset by favorable foreign exchange impact of approximately $19 million for the third quarter and approximately $35 million for the first nine months of 2011, and improved price.

Net sales in the Pacific Rim increased in the third quarter and first nine months of 2011. The increase in sales for the third quarter was primarily driven by foreign exchange impact of approximately $6 million, which was partially offset by unfavorable volume and mix. The increase in sales for the first nine months was driven by volume and favorable foreign exchange impact of approximately $14 million, partially offset by less favorable mix.

Cost of goods sold in the third quarter of 2011 was 74.5% of net sales, compared to 76.8% for the same period in 2010. Cost of goods sold in the first nine months of 2011 was 75.4% of net sales, compared to 77.0% for the same period in 2010. The percentage decreases were primarily the result of reductions in manufacturing costs.

SG&A expenses in the third quarter of 2011 were $118.8 million, or 15.4% of net sales, and in the first nine months of 2011 were $361.1 million, or 16.4% of net sales, compared to $125.2 million, or 16.9% of net sales, and $400.5 million, or 18.9% of net sales for the corresponding periods in 2010. The decreases were due to reductions in core SG&A expenses, partially offset by an asset impairment charge of $2.2 million for a European office building. In addition 2010, was impacted by $13.5 million of CEO

transition costs, of which $11.2 million were recorded in the first quarter of 2010, with the remainder recorded in the third quarter of 2010 and a $6.1 million asset impairment charge related to the termination of our flight operations, which was recorded in the first half of 2010. We also recorded an asset impairment charge of $2.1 million in the first half of 2010 for a European warehouse facility due to the decline in the commercial property sector.

Equity earnings from our WAVE joint venture were $15.4 million for the third quarter of 2011 compared to $13.2 million in the third quarter of 2010, and $44.4 million for the first nine months of 2011 compared to $38.6 million in first nine months of 2010. See Note 7 to the Condensed Consolidated Financial Statements for further information.

Interest expense was $11.3 million for the third quarter of 2011 compared to $3.9 million in the third quarter of 2010. Interest expense was $37.6 million in the first nine months of 2011 compared to $11.8 million in first nine months of 2010. Higher expenses in both periods were primarily due to the fourth quarter 2010 refinancing of our debt, which increased outstanding debt balances and interest rates compared to our previous credit facility.

Income tax expense was $30.6 million and $20.5 million for the third quarter of 2011 and 2010, respectively. The effective tax rate for the third quarter of 2011 was 36.8% as compared to a rate of 45.5% for the same period of 2010. The effective tax rate for 2011 was lower than 2010 due to the reduction of unbenefited foreign losses. Additionally, in the third quarter of 2010, we realized a partial release of state valuation allowances based on our projected ability to utilize the deferred tax assets to offset future taxable income.

Income tax expense was $78.0 million and $72.7 million for the first nine months of 2011 and 2010, respectively. The effective tax rate for the first nine months of 2011 was 42.9% versus 69.4% for the same period of 2010. The effective tax rate for the first nine months of 2011 was lower than the first nine months of 2010 due to the enactment of the federal healthcare reform legislation in March 2010.

increased in the first nine months of the year on favorable foreign exchange of approximately $19 million combined with positive price and mix.

Net sales in the Pacific Rim increased in the third quarter on favorable foreign exchange of approximately $3 million, partially offset by lower volume primarily in Australia. Net sales in the Pacific Rim increased in the first nine months of the year on favorable foreign exchange of approximately $7 million and higher volumes, which were partially offset by less favorable mix.

Operating income increased for the third quarter as price offset inflation, mix improved, earnings from WAVE increased, and SG&A decreased. These favorable variables more than offset lower volumes and higher manufacturing costs. Operating income increased in the first nine months of 2011 as improvements in price, volume, mix, SG&A expense, equity earnings from WAVE and reduced manufacturing costs were partially offset by inflation.

Net sales in the Americas increased in the third quarter and first nine months, as reduced volumes were more than offset by improvements in mix and price.

Net sales declines in the European markets for both periods reflects the volume reductions related to the restructuring of our European flooring business, which included the exit of the residential flooring business, and the simplification of our country and product offerings. Excluding the impact of these actions, year on year volumes were down slightly in the third quarter, and year over year volumes in the first nine months were flat. Net sales in the third quarter of 2011 benefitted from favorable foreign exchange of approximately $9 million, and net sales in the first nine months of 2011 benefitted from favorable foreign exchange of approximately $16 million.

Net sales in the Pacific Rim decreased in the third quarter, as declines in volume and mix primarily in Australia were partially offset by favorable foreign exchange of approximately $3 million. Net sales in the Pacific Rim increased in the first nine months of the year on favorable foreign exchange of approximately $7 million and higher volumes, which were partially offset by less favorable mix.

Operating income improved for the third quarter and first nine months of 2011 compared to the same periods in 2010. In both periods, reduced manufacturing costs, improved price and reductions in SG&A expenses offset volume declines and raw material inflation. Third quarter 2010 results were impacted by approximately $5.5 million of costs related to the closure of our Montreal, Canada, facility and approximately $7.0 million due to laminate duty refunds.

The operating losses for Resilient Flooring Europe for the third quarter and first nine months of 2011 included $2.4 million and $16.8 million, respectively, of severance and restructuring related costs. The third quarter and first nine months of 2010 include charges of $15.1 million related to the restructuring of the European business. In addition to the severance and restructuring charges, the losses include fixed asset impairment charges of $2.2 million recorded in the third quarter of 2011 and $2.1 million recorded in the first quarter of 2010.

Net sales increased in the third quarter as higher volumes were partially offset by unfavorable price and mix. Net sales for the first nine months of the year were flat as modest improvements in price were offset by unfavorable mix and significant first quarter volume declines in US residential markets.

Operating income increased for the third quarter, primarily due to reduced manufacturing and SG&A costs and favorable input costs when compared to the prior year due to the significant lumber inflation experienced in the third quarter of 2010. Operating income increased in the first nine months of the year due to reduced manufacturing and SG&A costs and favorable input costs, which were partially offset by reduced volumes. Additionally, the third quarter and first nine months of 2010 included $10.5 million of fixed asset write downs and severance charges related to the closure of two manufacturing facilities.

Management’s Discussion and Analysis of Financial Condition and Results of Operations
(dollar amounts in millions)

Operating income for both periods improved primarily due to reduced SG&A expenses, while the third quarter benefitted from stronger volumes, partially offset by less favorable product mix.

Unallocated Corporate

Unallocated corporate expense of $9.3 million in the third quarter of 2011 and $30.0 million for the first nine months decreased from $9.8 million and $39.2 million, respectively, in the prior year. The third quarter and first nine months of 2011 included a $6.2 million and $18.6 million lower pension credit as compared to 2010. In addition, 2010 was impacted by $13.5 million of CEO transition costs, of which $11.2 million were recorded in the first quarter of 2010 with the remainder recorded in the third quarter of 2010 and a $6.1 million asset impairment charge related to the termination of our flight operations which was recorded in the first half of 2010. After consideration of these items, corporate expenses declined in both 2011 periods due to lower headcount and professional services spending.

FINANCIAL CONDITION AND LIQUIDITY

Cash Flow

Operating activities for the first nine months of 2011 provided $129.9 million of cash, a decrease of $11.4 million from the $141.3 million of cash provided for the first nine months of 2010. The decrease was primarily due to a 2011 increase in inventories (compared to a decrease in 2010), higher restructuring payments, and a higher increase in receivables, partially offset by higher earnings.

Net cash used for investing activities was $42.4 million for the first nine months of 2011, compared to $3.9 million in the first nine months of 2010. This change was primarily due to increased purchases of property, plant and equipment in 2011.

Net cash used for financing activities was $32.2 million for the first nine months of 2011, compared to $27.5 million during the first nine months of 2010. Net cash used in 2011 was impacted by $25.0 million of payments on our revolving credit facility and refinancing costs of $7.9 million. Net cash used in 2010 was impacted by payments of long-term debt of $32.0 million and the purchase of the 20% non-controlling interest in our Shanghai ceilings operations for $7.8 million.

Liquidity

Our liquidity needs for operations vary throughout the year. We retain lines of credit to facilitate our seasonal needs. On November 23, 2010, we executed a $1.05 billion senior credit facility arranged by Merrill Lynch, Pierce, Fenner & Smith, Inc., J.P. Morgan Securities, Inc. and Barclays Capital. This facility consists of a $250 million revolving credit facility (with a $150 million sublimit for letters of credit), a $250 million Term Loan A and a $550 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.

On March 10, 2011, we entered into an amendment pursuant to which the following changes were effected with respect to Term Loan B:

• The applicable margin for borrowings under Term Loan B was reduced (i) to 2.00% from 2.50% with respect to base rate borrowings, and (ii) to 3.00% from 3.50% with respect to LIBOR borrowings;

• The minimum interest rate for borrowings under Term Loan B was reduced from 1.50% to 1.00%; and

• The maturity date for Term Loan B was extended from May 23, 2017 to March 10, 2018. Until maturity, quarterly amortization payments on Term Loan B will continue in an amount equal to 0.25% of the original principal amount of Term Loan B.

In connection with the amendment to Term Loan B, we paid a $5.5 million prepayment premium, which represented one percent of the principal amount of Term Loan B and which was capitalized and is being

34

Management’s Discussion and Analysis of Financial Condition and Results of Operations
(dollar amounts in millions)

amortized into interest expense over the life of the loan. We also paid approximately $1.6 million of fees to third parties (banks, attorneys, etc.).

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 June 30, 2012, 4.0 to 1.0 after June 30, 2012 through September 30, 2013 and 3.75 to 1.0 after September 30, 2013. 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 nine months of 2011, 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. These swaps are designated as cash flow hedges to hedge 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.

Mandatory prepayments are required under the senior credit facility pursuant to an annual leverage test starting with the year ending December 31, 2011, 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 September 30, 2011, we had $376.9 million of cash and cash equivalents, $281.2 million in the U.S. and $95.7 million in various foreign jurisdictions.

Our current debt rating from S&P is BB- (negative) and from Moody’s is B1 (stable).

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 may also issue letters of credit at the request of ARC. The purchase and letter of credit commitments under the program expire in December 2013, subject to possible extensions thereafter.

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. As of September 30, 2011, the $21.7 million of unspent proceeds must be used for expenditures related to the construction of our new mineral wool plant and are therefore accounted for as restricted cash within other non-current assets.

On September 30, 2011, we had outstanding letters of credit totaling $70.4 million, of which $19.4 million was issued under the revolving credit facility, $50.6 million was issued under the securitization facility

35

Management’s Discussion and Analysis of Financial Condition and Results of Operations
(dollar amounts in millions)

($36.2 million of which related to the West Virginia bond issue) and $0.4 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 September 30, 2011
Foreign Financing Arrangements	Limit		Used		Available
Lines of credit available for borrowing	$	22.6		—	$	22.6
Lines of credit available for letters of credit		2.5	$	1.0		1.5
Total	$	25.1	$	1.0	$	24.1

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.

During the past year, our Board of Directors has 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 $200 million and will be incurred over several years, with most of the spending occurring in 2011 and 2012.

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.

Recently issued accounting standards

In September 2011, the Financial Accounting Standards Board (“FASB”) issued new guidance which is now part of Accounting Standards Codification (“ASC”) 350:“Intangibles — Goodwill and Other". The new guidance will permit an entity to first assess qualitative factors to determine whether it is “more likely than not” that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. Because the objective of this new guidance is to simplify how entities test for goodwill impairment it will not have a material impact on our financial statements.

In June 2011, the FASB issued new guidance which is now part of ASC 220: “Presentation of Comprehensive Income”.The new guidance will require 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 stockholders’ equity. The standard does not change the items which must be reported in other comprehensive income. These provisions are to be applied retrospectively and will be effective for us as of January 1, 2012. Because this guidance impacts presentation only, it will have no effect on our financial condition, results of operations or cash flows.

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 2010 annual report on Form 10-K. There have been no material changes in our financial instruments or market risk exposures since December 31, 2010.

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 September 30, 2011, 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. No change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Act) occurred during the fiscal quarter ended September 30, 2011 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
