Accounting Policies [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 “AWI,” the “Company,” “we,” “our” or “us” in these notes, we are referring to AWI and its subsidiaries. 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, 2016. 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, 2016. 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. Operating results for the second quarter and first six months of 2017 and 2016 included in this report are unaudited. 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. On April 1, 2016, we completed our separation of Armstrong Flooring, Inc. (“AFI”). AFI’s historical financial results have been reflected in AWI’s Consolidated Financial Statements as a discontinued operation for all periods presented. Separation costs for the three and six months ended June 30, 2016 were $3.9 million and $31.0 million, respectively. Separation costs were recorded within the Unallocated Corporate segment. Separation costs primarily related to outside professional services and employee compensation, retention and severance accruals. On January 13, 2017, we acquired the business and assets of Tectum, Inc. (“Tectum”), based in Newark, Ohio. Tectum is a manufacturer of acoustical ceiling, wall and structural solutions for commercial building applications with two manufacturing facilities. 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 and net realizable value charges, warranty reserves, 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. Certain amounts in the prior year’s Condensed Consolidated Financial Statements have been recast to conform to the 2017 presentation. Recently Adopted Accounting Standards In July 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-11, “Simplifying the Measurement of Inventory,” In March 2016, the FASB issued ASU 2016-09, “Improvements to Employee Share-Based Payment Accounting.” Recently Issued Accounting Standards In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers.” “Principal versus Agent Considerations (Reporting Gross versus Net),” “Identifying Performance Obligations and Licensing,” “Narrow-Scope Improvements and Practical Expedients,” “Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers,” Collectively, the revenue recognition ASC updates are effective for annual reporting periods beginning after December 15, 2017, but early adoption is permitted. We intend to adopt these standards effective January 1, 2018 using the modified retrospective transition method and also intend to apply all practical expedients related to completed contracts upon adoption. We are still evaluating the impact the adoption of these ASC updates will have on our financial condition, results of operations, cash flows and disclosures. Substantially all of our revenues are recognized from the sale of products with standard shipping terms, sales discounts and warranties. As such, and based on our evaluation to date, we do not believe adoption will have a material impact to us as we expect to continue to recognize substantially all of our revenues at a point in time. Our final evaluation of the impact of adopting these ASC updates is expected to be completed during the third quarter of 2017. In January 2016, the FASB issued ASU 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities,” In February 2016, the FASB issued ASU 2016-02, “Leases,” In August 2016, the FASB issued ASU 2016-15 , “Classification of Certain Cash Receipts and Cash Payments.” In March 2017, the FASB issued ASU 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost,”

Discontinued Operations [Abstract]
Acquisition and Discontinued Operations	NOTE 3. ACQUISITION AND DISCONTINUED OPERATIONS Acquisition of Tectum On January 13, 2017, in connection with the acquisition of Tectum, the $31.4 million purchase price for Tectum was allocated to the tangible and intangible assets acquired and the liabilities assumed based on their estimated fair values, with the remaining unallocated amount recorded as goodwill. The total fair value of tangible assets acquired, less liabilities assumed, in connection with the Tectum acquisition was $5.9 million. The total fair value of intangible assets acquired, comprised of amortizable customer relationships and non-amortizing brand names, was $16.5 million, resulting in $9.0 million of goodwill. All of the acquired goodwill is deductible for tax purposes. Separation and Distribution of AFI On April 1, 2016, in connection with the separation and distribution of AFI, we entered into several agreements with AFI that, together with a plan of division, provide for the separation and allocation between AWI and AFI of the flooring assets, employees, liabilities and obligations of AWI and its subsidiaries attributable to periods prior to, at and after AFI’s separation from AWI, and govern the relationship between AWI and AFI subsequent to the completion of the separation and distribution. These agreements include a Transition Services Agreement, a Tax Matters Agreement, an Employee Matters Agreement, a Trademark License Agreement, a Transition Trademark License Agreement and a Campus Lease Agreement. Under the Transition Services Agreement, AWI and AFI will provide various services to each other during a transition period expiring no later than December 31, 2017. We do not expect to extend the Transition Services Agreement beyond December 31, 2017. The following is a summary of the results of operations related to AFI, our former Resilient Flooring and Wood Flooring segments, which are presented as discontinued operations. Six Months Ended June 30, 2016 Net sales $ 284.4 Cost of goods sold 237.2 Gross profit 47.2 Selling, general and administrative expenses 50.5 Operating (loss) (3.3 ) Other non-operating expense, net 1.1 (Loss) from discontinued operations before income taxes (4.4 ) Income tax expense 0.1 (Loss) from discontinued operations $ (4.5 ) The following is a summary of total depreciation and amortization and capital expenditures related to AFI which are presented as discontinued operations and included as components of operating and investing cash flows on our consolidated statements of cash flows: Six Months Ended June 30, 2016 Depreciation and amortization $ 11.4 Purchases of property, plant and equipment (12.1 ) European Resilient Flooring On December 4, 2014, our Board of Directors approved the cessation of funding to our DLW subsidiary, which at that time was our European flooring business. As a result, DLW management filed for insolvency in Germany on December 11, 2014. The German insolvency court subsequently appointed an administrator (the “Administrator”) to oversee DLW operations. As of December 4, 2014, DLW had a net liability of $12.9 million, representing assets of $151.9 million and liabilities of $164.8 million, which were removed from our balance sheet. This net liability was recognized as a contingent liability on our consolidated balance sheet pending the closure of the insolvency proceeding. The net liability, included within Accounts payable and accrued expenses on our Condensed Consolidated Balance Sheets, was $11.9 million as of March 31, 2017. In April 2017, we entered into a settlement agreement and mutual release with the Administrator on behalf of the DLW estate to settle all claims of the Administrator related to the insolvency for a cash payment of $11.8 million. DLW was previously shown within our Resilient Flooring reporting segment. The following is a summary of the results related to the flooring businesses which are included in discontinued operations.

Severance and Related Costs	NOTE 10. SEVERANCE AND RELATED COSTS During the first quarter of 2016, we recorded $2.4 million in Unallocated Corporate for severance and related costs (including for our former Chief Executive Officer) as a result of the separation of AFI. These costs are reflected within Separation costs on the Condensed Consolidated Statements of Earnings.

Income Tax Expense	NOTE 11. INCOME TAX EXPENSE Three Months Ended Six Months Ended June 30, June 30, 2017 2016 2017 2016 Earnings from continuing operations before income taxes $ 70.1 $ 41.3 $ 125.5 $ 46.2 Income tax expense 28.6 24.7 53.2 36.7 Effective tax rate 40.8 % 59.8 % 42.4 % 79.4 % Excluding the impact of the increase in pre-tax income, the effective rate for the second quarter and first six months of 2017 was lower in comparison to the same periods in 2016 as income tax expense in 2016 was negatively impacted by the separation of AFI. It is reasonably possible that the amount of unrecognized tax benefits could significantly increase or decrease within the next twelve months. However, an estimate of the range of reasonably possible outcomes cannot be made. Changes to unrecognized tax benefits could result from the completion of ongoing examinations, the expiration of the statute of limitations or other unforeseen circumstances. As of June 30, 2017, we consider foreign unremitted earnings to be permanently reinvested.

Debt Disclosure [Abstract]
Debt	NOTE 12. DEBT As of June 30, 2017 and December 31, 2016, our long-term debt included borrowings outstanding under our $1,050.0 million credit facility, which is comprised of a $200.0 million revolving credit facility (with a $150.0 million sublimit for letters of credit), a $600.0 million Term Loan A and a $250.0 million Term Loan B. We also have a $25.0 As of June 30, 2017, the outstanding balance on our revolving credit facility, classified as Short-term debt on our Condensed Consolidated Balance Sheets, was $15.0 million. As of December 31, 2016, there were no borrowings outstanding on our revolving credit facility. As of June 30, 2017 and December 31, 2016, our outstanding long-term debt included a $35.0 million variable rate, tax-exempt industrial development bond that financed the construction of a U.S. plant in prior years. We utilize lines of credit and other commercial commitments in order to ensure that adequate funds are available to meet operating requirements. Letters of credit are currently arranged through our revolving credit facility, our bi-lateral facility and our securitization facility. In addition, our foreign subsidiaries’ available lines of credit are available for letters of credit and guarantees. Letters of credit are issued to third party suppliers, insurance institutions and financial institutions and typically can only be drawn upon in the event of AWI’s failure to pay its obligations to the beneficiary. The following table presents details related to our letters of credit: As of June 30, 2017 Financing Arrangements Limit Used Available Revolving credit facility $ 150.0 $ - $ 150.0 Bi-lateral facility 25.0 19.2 5.8 Accounts receivable securitization facility 40.0 36.2 3.8 Foreign lines of credit 0.2 - 0.2 Total $ 215.2 $ 55.4 $ 159.8 As of December 31, 2016, $4.0 million of letters of credits issued under our accounts receivable securitization facility in excess of our maximum limit were classified as restricted cash and reported as a component of Cash and cash equivalents on our Condensed Consolidated Balance Sheets. As of June 30, 2017, no amounts were classified as restricted cash. In February 2017, we repriced the interest rate on our Term Loan B borrowing, resulting in a lower LIBOR spread (2.75% vs. 3.25%). The maturity date and all other terms and conditions remained unchanged. In connection with the refinancing, we paid $0.6 million of bank, legal and other fees, the majority of which were capitalized.

During 2016, actuarial gains and losses were amortized into future earnings over the expected remaining service period of plan participants, which was approximately eight years for our U.S. defined-benefit pension plans. For 2017, actuarial gains and losses are amortized over the remaining life expectancy of plan participants, which are approximately 20 years for our U.S. defined-benefit pension plans. Our U.S. defined benefit Retirement Income Plan (“RIP”) was amended to freeze accruals for salaried non-production employees, effective December 31, 2017. The impact of this amendment resulted in a reduction to our December 31, 2016 projected benefit obligation with a corresponding increase to unrecognized loss, resulting in no curtailment gain or loss. The impact of this amendment has been reflected in the net periodic pension credit for 2017.

Fair Value Disclosures [Abstract]
Financial Instruments	NOTE 14. FINANCIAL INSTRUMENTS We do not hold or issue financial instruments for trading purposes. The estimated fair values of our financial instruments are as follows: June 30, 2017 December 31, 2016 Carrying amount Estimated fair value Carrying amount Estimated fair value Assets/(Liabilities), net: Total long-term debt, including current portion $ (865.4 ) $ (865.6 ) $ (873.6 ) $ (873.7 ) Foreign currency contracts (0.4 ) (0.4 ) 1.6 1.6 Natural gas contracts (0.3 ) (0.3 ) 1.0 1.0 Interest rate swap contracts 6.8 6.8 6.9 6.9 The carrying amounts of cash and cash equivalents, receivables, accounts payable, accrued expenses, and short-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 A and Term Loan B debt, respectively. 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, and is 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. 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. Three levels of inputs may be used to measure fair value: 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; or 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. The fair value measurement of assets and liabilities measured at fair value on a recurring basis and reported on the consolidated balance sheets is summarized below: June 30, 2017 December 31, 2016 Fair value based on Fair value based on Quoted, active markets Other observable inputs Quoted, active markets Other observable inputs Level 1 Level 2 Level 1 Level 2 Assets, net: Foreign currency contracts $ (0.4 ) $ - $ 1.6 $ - Natural gas contracts - (0.3 ) - 1.0 Interest rate swap contracts - 6.8 - 6.9 We do not have any financial assets or liabilities that are valued using Level 3 (unobservable) inputs.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	NOTE 15. 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, cash flows 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 an investment-grade credit rating. 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 do not post nor do we receive cash collateral with any counterparty for 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 manufacturing process 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. The contracts are based on forecasted usage of natural gas measured in mmBtu’s. There is a high correlation between the hedged item and the hedge instrument. The gains and losses on these instruments offset gains and losses on the transactions being hedged. These instruments are designated as cash flow hedges. As of June 30, 2017 and December 31, 2016, the notional amount of these hedges was $12.3 million and $7.4 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 three and six months ended June 30, 2017 and 2016. 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. Our major foreign currency exposures as of June 30, 2017, based on operating profits by currency, are to the Russian ruble, Canadian dollar and Chinese renminbi. 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 $33.2 million as of June 30, 2017 and $34.6 million as of December 31, 2016. 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 three and six months ended June 30, 2017 and 2016. 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. The following table summarizes our interest rate swaps as of June 30, 2017: Trade Date Notional Amount Coverage Period Risk Coverage November 13, 2016 $ 250.0 November 2016 to March 2018 Term Loan A November 13, 2016 $ 200.0 November 2016 to March 2021 Term Loan A April 1, 2016 $ 100.0 April 2016 to March 2023 Term Loan B In connection with the refinancing of our credit facilities in April 2016, $450.0 million of notional amount Term Loan B swaps with a trade date of March 27, 2012 were settled and $10.7 million of losses recorded as a component of accumulated other comprehensive income were reclassified to interest expense during the three months ended March 31, 2016, with the cash payment for the settlement of this swap occurring during the second quarter of 2016. Under the terms of the Term Loan A swap with trade dates of November 13, 2016, we receive 1-month LIBOR and pay a fixed rate over the hedged period. Under the terms of our Term Loan B swap with a trade date of April 1, 2016, we receive the greater of 3-month LIBOR or a 0.75% LIBOR Floor and pay a fixed rate over the hedged period. These swaps are designated as cash flow hedges against changes in LIBOR for a portion of our variable rate debt. 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 mark-to-market gains or losses on the ineffective portion of hedges are recognized in interest expense. There was no earnings impact of the ineffective portion of these hedges for the three and six months ended June 30, 2017 and 2016.

Litigation and Related Matters

Litigation and Related Matters	6 Months Ended

Commitments And Contingencies Disclosure [Abstract]
Litigation and Related Matters	NOTE 18. LITIGATION AND RELATED MATTERS ENVIRONMENTAL MATTERS Environmental Compliance 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 Sites Summary We are actively involved in the investigation, closure and/or remediation of existing or potential environmental contamination under the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”) and state Superfund and similar environmental laws at several domestically 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 and 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. We are currently pursuing coverage and recoveries under those policies with respect to certain of the sites, including the St. Helens, OR site, the Macon, GA site and the Elizabeth City, NC site, each of which is summarized below. These efforts include two active and independent litigation matters against legacy primary and excess policy insurance carriers for recovery of fees and costs incurred by us in connection with our investigation and remediation activities for such sites. Other than disclosed below, we are unable to predict the outcome of these matters or the timing of any recoveries, whether through settlement or otherwise. We are also unable to predict the extent to which any recoveries might cover our final share of investigation and remediation costs for these sites. Our final share of investigation and remediation costs may exceed any such recoveries, and such amounts net of insurance recoveries may be material. During the second quarter of 2017, we entered into settlement agreements with two legacy insurance carriers to resolve ongoing litigation and recover fees and costs previously incurred by us in connection with certain environmental sites. These settlements were not material to our financial statements. We anticipate that we may enter into additional settlement agreements that may or may not be material in 2017 with other, but not all, legacy insurers to obtain reimbursement for environmental site expenses. 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, the site activities of other parties, whether liability is being disputed, the terms of any existing agreements and experience with similar matters, and the effect of our October 2006 Chapter 11 reorganization upon the validity of the claim. Specific Material Events St Helens, OR In August 2010, we entered into a Consent Order (the “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, OR facility, which was previously owned by Kaiser and then OC. The Consent Order requires that we and Kaiser complete a remedial investigation and feasibility study (“RI/FS”) on the portion of the site owned by us (“Owned Property”), which is comprised of Upland and Lowland areas. The Consent Order further requires us, Kaiser and OC to conduct an RI/FS in the In-Water area of the adjacent Scappoose Bay. Costs and responsibilities for investigation, including the current RI/FS, for the Owned Property have been shared with Kaiser pursuant to a cost sharing agreement with Kaiser. Costs and responsibilities for the investigation with respect to the in-water areas that we do not own have been shared with Kaiser and OC pursuant to a cost sharing agreement with Kaiser and OC. On September 14, 2016, the parties submitted a Feasibility Study to the ODEQ proposing remedial action options for the Upland area. We have participated in the investigation phase for the Lowland area of the Owned Property and the Scappoose Bay and have been working with the ODEQ, Kaiser and OC to finalize the reports to move to the Feasibility Study phase. We have determined that it is probable that remedial action for certain portions of the Lowland area of the Owned Property will be required. The current estimate of our future liability at the site includes any remaining known investigation work required by the Consent Order and the current projected cost of remedial actions in the Upland area. At this time, we are unable to reasonably estimate any remediation costs that we may ultimately incur with respect to the Lowland portion of the Owned Property or the Scappoose Bay or whether the projected costs for the areas we have included in our current estimate will increase. Additional investigative or remedial action required by the ODEQ could result in additional costs greater than the amounts currently estimated. As discussed above, we are currently unable to predict the outcome or the timing of our insurance recovery proceedings. Accordingly, additional estimated costs for this matter may be incurred without regard for, and prior to, the resolution of our insurance recovery proceedings. On September 30, 2016, Kaiser filed a voluntary petition for relief under Chapter 11 of the Bankruptcy Code in the U.S. Bankruptcy Court for the Western District of North Carolina (Case No. 16-31602). AWI, OC and the ODEQ have all been included on the master list of potential creditors filed with the Bankruptcy Court for notice purposes. By order dated October 14, 2016, the Bankruptcy Court formed a statutory committee of unsecured creditors, to which we were appointed to serve, along with OC and The Boeing Company. The Committee is charged with, among other things, maximizing recovery of all unsecured creditor claims, including claims of Kaiser and ODEQ. The Chapter 11 case impacts Kaiser’s ongoing participation in the RI/FS process, as well as the ODEQ consent order and cost sharing agreements. It may also delay implementation of remedial actions for the Upland area, as well as completion of the investigation phase for the Lowland area of the Owned Property and the Scappoose Bay. At this time, we are unable to predict whether and to what extent Kaiser intends to satisfy its environmental remediation obligations and liability to ODEQ. Specifically, we are unable to predict whether Kaiser will negotiate a settlement that would discharge its liability for the site, or whether it has sufficient insurance or other assets to cover its anticipated share of any site liability. Kaiser’s shares under cost sharing agreements were being funded by certain insurance policies, which comprised substantially all of Kaiser’s assets. If Kaiser, whether as a result of bankruptcy or otherwise, or OC are unwilling or unable to fulfill their obligations under the cost sharing agreements, or seek to contest or challenge the allocations, or if Kaiser’s insurance policies are unable to fund Kaiser’s share of environmental liability, it could result in additional cost to us greater than the amounts currently estimated and those costs may be material. Macon, GA The U.S. Environmental Protection Agency (“EPA”) has listed two landfills located on a portion of our Building Products facility in Macon, GA, along with the former Macon Naval Ordnance Plant landfill adjacent to our property, portions of Rocky Creek, and certain tributaries leading to Rocky Creek (collectively, the “Macon Site”) as a Superfund site on the National Priorities List due to the presence of contaminants, most notably polychlorinated biphenyls (“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, the Wastewater Treatment Plant Landfill (the “WWTP Landfill,” also known as “Operable Unit 1”). We concluded the investigative phase of the Removal Action for the WWTP Landfill and submitted our final Engineering Evaluation/Cost Analysis (“EE/CA”) to the EPA in 2013. The EPA subsequently approved the EE/CA and issued an Action Memorandum in July 2013 selecting our recommended remedy for the Removal Action. In July 2014, we entered into an Administrative Order on Consent for Removal Action with the EPA for the WWTP Landfill. The EPA approved the Removal Action Work Plan on March 30, 2015 and the removal work commenced in the third quarter of 2015. The Operable Unit 1 response action for the WWTP Landfill is complete and the final report was submitted to the EPA on October 11, 2016. The EPA approved the final report on November 28, 2016, and a Post-Removal Control Plan (the “Plan”) was submitted to the EPA on March 28, 2017. We will implement the Plan once it is approved. That Plan will monitor the effectiveness of the WWTP Landfill response action and our estimate of future liabilities includes these tasks. It is probable that we will incur field investigation, engineering and oversight costs associated with a RI/FS with respect to the remainder of the Superfund site, which includes the other landfill on our property, as well as areas on and adjacent to AWI’s property and Rocky Creek (the “Remaining Site,” also known as “Operable Unit 2”). On September 25, 2015, AWI and six other Potentially Responsible Parties (“PRPs”) received a Special Notice Letter from the EPA under CERCLA inviting AWI and the PRPs to enter into the negotiation of a Settlement Agreement (formerly known as an Administrative Order on Consent) to conduct an RI/FS of Operable Unit 2. We, along with the other PRPs, submitted a good faith offer to the EPA in response to the Special Notice Letter to conduct RI/FS. We have not received a response to our good faith offer and have not yet entered into an Order with the EPA for Operable Unit 2. We have not yet commenced an investigation of this portion of the site. We anticipate that the EPA will require significant investigative work for Operable Unit 2 and that we may ultimately incur costs in remediating any contamination discovered during the RI/FS. The current estimate of future liability at this site includes only our estimated share of the costs of the investigative work that, at this time, we anticipate the EPA will require the PRPs to perform. We are unable to reasonably estimate AWI’s final share of the costs or the total costs associated with the investigation work or any resulting remediation therefrom, although such amounts may be material. Elizabeth City, NC This site is a former cabinet manufacturing facility that was operated by Triangle Pacific Corporation, now known as Armstrong Wood Products, Inc. (“Triangle Pacific”), from 1977 until 1996. The site was formerly owned by the U.S. Navy (“Navy”) and Westinghouse, now CBS Corporation (“CBS”). We assumed ownership of the site when we acquired the stock of Triangle Pacific in 1998. Prior to our acquisition, the NC Department of Environment and Natural Resources listed the site as a hazardous waste site. In 1997, Triangle Pacific entered into a cost sharing agreement with Westinghouse whereby the parties agreed to share equally in costs associated with investigation and potential remediation. In 2000, Triangle Pacific and CBS entered into an Administrative Order on Consent to conduct an RI/FS with the EPA for the site. In 2007, we and CBS entered into an agreement with the Navy whereby the Navy agreed to pay one third of defined past and future investigative costs up to a certain amount, which has now been exhausted. The EPA approved the RI/FS work plan in August 2011. In January 2014, we submitted the draft Remedial Investigation and Risk Assessment reports and conducted supplemental investigative work based upon agency comments to those reports. The EPA has requested a schedule for next steps (e.g. feasibility study) working toward a Proposed Plan and Record Of Decision in 2018. If remediation is required, the related costs may be material, although we expect these costs to be shared with CBS and the Navy. Summary of Financial Position Liabilities of $5.5 million as of June 30, 2017 and $4.7 million as of December 31, 2016 were recorded for potential environmental liabilities that we consider probable and for which a reasonable estimate of the probable liability could be made. During the three and six months ended June 30, 2017, we recorded reserves for potential environmental liabilities of $0.7 million and $1.3 million, respectively. During the three and six months ended June 30, 2016, we recorded reserves for potential environmental liabilities of $0.1 million and $0.8 million, respectively. 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, and adjusted to reflect amounts actually incurred and paid. 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 insurance recoveries when probable. For insurance recoveries that are reimbursements of prior environmental expenditures, the income statement impact is recorded within cost of goods sold, SG&A expenses and/or discontinued operations, which are the same income statement categories where environmental expenditures were historically recorded. Insurance recoveries in excess of historical environmental spending, if any, would be recorded on the balance sheet as a part of other long-term liabilities and released as future environmental spending occurs. Actual costs to be incurred at identified sites may vary from our estimates. Based on our knowledge of the identified sites, it is not possible to reasonably estimate future costs in excess of amounts already recognized. 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 business, including matters involving our products, intellectual property, relationships with suppliers, relationships with distributors, relationships with competitors, employees and other matters. From time to time, for example, we may be a party to litigation matters that involve product liability, tort liability and other claims under various allegations, including illness due to exposure to certain chemicals used in the workplace; or medical conditions arising from exposure to product ingredients or the presence of trace contaminants. Such allegations may involve multiple defendants and relate to legacy products that we and other defendants purportedly manufactured or sold. We believe that any current claims are without merit and intend to defend them vigorously. For these matters, we also may have rights of contribution or reimbursement from other parties or coverage under applicable insurance policies. When applicable and appropriate, we will pursue coverage and recoveries under those policies, but are unable to predict the outcome of those demands. While complete assurance cannot be given to the outcome of these proceedings, we do not believe that any current claims, individually or in the aggregate, will have a material adverse effect on our financial condition, liquidity or results of operations.

Recently Adopted and Recently Issued Accounting Standards	Recently Adopted Accounting Standards In July 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-11, “Simplifying the Measurement of Inventory,” In March 2016, the FASB issued ASU 2016-09, “Improvements to Employee Share-Based Payment Accounting.” Recently Issued Accounting Standards In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers.” “Principal versus Agent Considerations (Reporting Gross versus Net),” “Identifying Performance Obligations and Licensing,” “Narrow-Scope Improvements and Practical Expedients,” “Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers,” Collectively, the revenue recognition ASC updates are effective for annual reporting periods beginning after December 15, 2017, but early adoption is permitted. We intend to adopt these standards effective January 1, 2018 using the modified retrospective transition method and also intend to apply all practical expedients related to completed contracts upon adoption. We are still evaluating the impact the adoption of these ASC updates will have on our financial condition, results of operations, cash flows and disclosures. Substantially all of our revenues are recognized from the sale of products with standard shipping terms, sales discounts and warranties. As such, and based on our evaluation to date, we do not believe adoption will have a material impact to us as we expect to continue to recognize substantially all of our revenues at a point in time. Our final evaluation of the impact of adopting these ASC updates is expected to be completed during the third quarter of 2017. In January 2016, the FASB issued ASU 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities,” In February 2016, the FASB issued ASU 2016-02, “Leases,” In August 2016, the FASB issued ASU 2016-15 , “Classification of Certain Cash Receipts and Cash Payments.” In March 2017, the FASB issued ASU 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost,”
