BUSINESS AND BASIS OF PRESENTATION	BUSINESS AND BASIS OF PRESENTATION Business Armstrong Flooring, Inc. is a leading global producer of resilient flooring products for use primarily in the construction and renovation of residential, commercial and institutional buildings. AFI designs, manufactures, sources and sells resilient flooring products in North America and the Pacific Rim. On December 31, 2021, following our Board's determination that a sale of the Company or other strategic transaction, if completed, would be in the best interests of the Company and the best means to maximize value for the Company's stockholders and other stakeholders, we announced that we had initiated a process for the potential sale of the Company and consideration of other strategic alternatives. Separation On April 1, 2016, we became an independent company as a result of the Separation which was effected by the Distribution. The Spin-off resulted in AFI and AWI becoming two independent, publicly traded companies, with AFI owning and operating the Resilient Flooring and Wood Flooring segments and AWI continuing to own and operate a ceilings business. In connection with the completion of the Spin-off, we entered into several agreements with AWI that provided for the separation and allocation between AFI and AWI of the assets, employees, liabilities and obligations of AWI and its subsidiaries attributable to periods prior to, at and after the Spin-off. These agreements also govern the relationship between AFI and AWI subsequent to the completion of the Spin-off. On June 30, 2021, we terminated the Campus Lease Agreement with AWI. Discontinued Operations On November 14, 2018, AFI entered into a Stock Purchase Agreement with TZI, a Delaware corporation and an affiliate of AIP, to sell its North American wood flooring business. On December 31, 2018, AIP completed the purchase of all of the issued and outstanding shares of Armstrong Wood Products, Inc., a Delaware corporation, including its direct and indirect wholly owned subsidiaries. For the year ended December 31, 2019, a $10.4 million gain on disposal of discontinued operations was realized primarily due to the resolution of our anti-dumping case. There was no discontinued operations activity for the years ended December 31, 2021 and 2020. COVID As the COVID-19 pandemic continues, the Company has seen the overall impact on its business decline. However, we remain committed to safeguarding our employees and the communities in which we operate, while continuing to deliver our products to customers. The Company has experienced the impact of the imbalance of global shipping capacity and demand which has led to delays in the receipt of goods from China and Vietnam at U.S. ports. Additionally, while overall economic activity has improved, some of the Company's customers' commercial projects in the retail, office, medical and educational sectors continue to be postponed. These factors have led to a softer demand environment in certain states and channels. The ultimate duration and impact of the pandemic on our future results is unknown. Reclassifications Certain reclassifications have been made to prior year amounts to conform with current year classifications. Going Concern These financial statements have been prepared assuming that the Company will continue as a going concern. For the year ended December 31, 2021, the Company had a net loss of $53.0 million. As of December 31, 2021, the Company had an accumulated deficit of $356.2 million. The ability of the Company to continue as a going concern is dependent on the Company maintaining adequate capital and liquidity to fund operating losses until it returns to profitability. On December 31, 2021, AFI announced that it entered into the 2021 ABL Amendments and the 2021 Term Loan Amendments, that became effective as of December 30, 2021. In connection with the Term Loan Amendment, the Company's current term loan lender, loaned AFI an aggregate principal of $35 million to provide additional liquidity to the Company. Also on December 31, 2021, following our Board's determination that a sale of the Company or other strategic transaction, if completed, would be in the best interests of the Company and the best means to maximize value for the Company's stockholders and other stakeholders, we announced that we had initiated a process for the potential sale of the Company and consideration of other strategic alternatives. The 2021 ABL Amendments and the 2021 Term Loan Amendments contain provisions that require the Company to adhere to various covenants, including meeting certain milestones relating to the sale of the Company and there can be no assurance that the Company will be able to comply with these covenants. The Company is required to refinance the Credit Agreements no later than June 30, 2022, even if a sale of the Company or other strategic transaction has not been consummated prior to such date. The failure to comply with any of these covenants would constitute a default under the terms of the Credit Agreements which could have an adverse effect on the Company, including affecting its access to liquidity. The Company continues to face certain risks and uncertainties that have been affecting its business and operations. While the Company has implemented substantial pricing actions and evaluates other initiatives that could enhance its liquidity, including the potential sale of the Company, there can be no assurances that these actions will be successful. Substantial doubt about the Company's ability to continue as a going concern exists because the sale of the Company being completed or the Credit Agreements being extended beyond the June 30, 2022 refinancing requirement cannot be considered probable as they are not under our sole control. Additionally, based on current projections, as a result of continuing supply chain disruptions and continued inflationary pressures related to transportation, labor and raw materials, which are expected to continue through 2022, the forecasts do not provide the Company with reasonable certainty it will have the necessary liquidity to fund operations beyond June 30, 2022. As a result, the Company has classified amounts outstanding under the Credit Agreements as Current installments of long-term debt at December 31, 2021 on the Consolidated Balance Sheets. See Note 8, Debt, for additional details. Asset Impairment Review

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Consolidation Policy The Consolidated Financial Statements and accompanying data in this Form 10-K include the accounts of AFI and its subsidiaries. Intercompany accounts and transactions have been eliminated from the Consolidated Financial Statements. Change in Accounting Principle During the fourth quarter of 2021, the Company changed its method of accounting for U.S. based inventories from the LIFO method to the FIFO method. We believe that this change in accounting method is preferable as it results in a better matching of revenue and expense, it more closely resembles the physical flow of inventory, is a more consistent method to value inventory across our businesses, and results in improved comparability with industry peers. The effects of this change have been retroactively applied to all periods presented. This change resulted in a decrease to accumulated deficit of $3.0 million as of January 1, 2019. In addition, certain financial statement line items in our Consolidated Balance Sheet for December 31, 2020, as well as our Consolidated Statement of Operations and Consolidated Statements of Cash Flows for the years ended December 31, 2020 and 2019 were adjusted as follows: Consolidated Balance Sheet as of December 31, 2020 Originally Reported Effect of Change As Adjusted Inventories $ 122.9 $ 5.2 $ 128.1 Accumulated deficit (308.4) 5.2 (303.2) Consolidated Statement of Operations for the Year Ended December 31, 2020 Originally Reported Effect of Change As Adjusted Cost of goods sold $ 501.3 $ (0.5) $ 500.8 Income (loss) from continuing operations (63.6) 0.5 (63.1) Basic and diluted (loss) per share of common stock (2.90) 0.02 (2.88) Consolidated Statement of Operations for the Year Ended December 31, 2019 Originally Reported Effect of Change As Adjusted Cost of goods sold $ 541.0 $ (1.7) $ 539.3 Income (loss) from continuing operations (68.9) 1.7 (67.2) Basic and diluted (loss) per share of common stock (2.42) 0.07 (2.35) Consolidated Statement of Cash Flows for the Year Ended December 31, 2020 Originally Reported Effect of Change As Adjusted Net (loss) $ (63.6) $ 0.5 $ (63.1) Inventories (9.7) (0.5) (10.2) Consolidated Statement of Cash Flows for the Year Ended December 31, 2019 Originally Reported Effect of Change As Adjusted Net (loss) $ (58.5) $ 1.7 $ (56.8) Inventories 14.1 (1.7) 12.4 Had the Company not made the above change in accounting principle, the Consolidated Balance Sheet for the year ended December 31, 2021 would have reflected Inventories of $128.9 million and Accumulated deficit of $373.8 million and the Company's Consolidated Statement of Operations for the year ended December 31, 2021 would have reflected Costs of goods sold of $588.1 million, Loss from continuing operations of $65.3 million and Loss per common share of $2.97 per share. Use of Estimates We prepare our financial statements in conformity with U.S. GAAP, which requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets, liabilities, revenues and expenses. When preparing an estimate, management determines the amount based upon the consideration of relevant internal and external information. Actual results may differ from these estimates. Revenue Recognition We recognize revenue when control of the promised goods is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods. Our primary performance obligation to our customers is the delivery of flooring products pursuant to purchase orders. Control of the products we sell generally transfers to our customers at the point in time when the goods are shipped. Our standard sales terms are primarily free-on-board shipping point. Our typical payment terms are 30 days and our sales arrangements do not contain any significant financing component for our customers. Our customer arrangements do not generate contract assets or liabilities that are material to the Consolidated Financial Statements. Each purchase order sets forth the transaction price for the products purchased under that arrangement. Some customer arrangements include variable consideration, such as volume rebates, some of which depend upon our customers meeting specified performance criteria, such as a purchasing level over a period of time. We use judgment to estimate the most likely amount of variable consideration at each reporting date. Costs to obtain a contract are capitalized and amortized over the life of the related contract when the incremental costs directly relate to a specific contract, generates or enhances resources of the company that will be used to satisfy performance of the terms of the contract and the cost are expected to be recovered from the customer. During the fourth quarter of 2020 we capitalized $1.1 million of costs to obtain a contract, related to a single new arrangement, which will be amortized over the three We disaggregate revenue based on customer geography as this category represents the most appropriate depiction of how the nature, timing and uncertainty of revenues and cash flows are impacted by economic factors. See Note 12, Revenue, to the Consolidated Financial Statements for our revenues disaggregated by geography. Warranties - We provide our customers with a product warranty that provides assurance that the products we sell meet standard specifications and are free of defects. We maintain a reserve for claims and related costs based on historical experience and periodically adjusts these provisions to reflect actual experience. See Note 3, Accounts and Notes Receivable, to the Consolidated Financial Statements for additional information. Sales Incentives - Sales incentives to customers are reflected as a reduction of net sales. Shipping and Handling Costs - We treat shipping and handling that occurs after customers obtain control of the products as a fulfillment activity and not as a promised service. Shipping and handling costs are reflected as a component of Cost of goods sold. Taxes - Taxes collected from customers and remitted to governmental authorities are reported on a net basis. Advertising Costs We recognize advertising expenses as they are incurred. Pension and Postretirement Benefits We have benefit plans that provide for pension, medical and life insurance benefits to certain eligible employees when they retire from active service. The cost of plan amendments that provide for benefits already earned by plan participants is amortized over the expected future working lifetime or the life expectancy of plan participants. A market-related value of plan assets methodology is utilized in the calculation of expected return on assets. The methodology recognizes gains and losses on long duration bonds immediately, while gains and losses on other assets are recognized in the calculation over a five-year period. We use a December 31 measurement date for our pension and postretirement benefit plans. See Note 9, Pension and Other Postretirement Benefit Programs, to the Consolidated Financial Statements for additional information. Taxes The provision for income taxes has been determined using the asset and liability approach of accounting for income taxes to reflect the expected future tax consequences of events recognized in the Consolidated Financial Statements. Deferred income tax assets and liabilities are recognized by applying enacted tax rates to temporary differences that exist as of the balance sheet date which result from differences in the timing of reported taxable income between tax and financial reporting. We reduce the carrying amounts of deferred tax assets by a valuation allowance if, based on the available evidence, it is more likely than not that such assets will not be realized. The need to establish valuation allowances for deferred tax assets is assessed quarterly. In assessing the requirement for, and amount of, a valuation allowance in accordance with the more likely than not standard for all periods, we give appropriate consideration to all positive and negative evidence related to the realization of the deferred tax assets. This assessment considers, among other matters, the nature, frequency and severity of current and cumulative losses, forecasts of future profitability and foreign source income, the duration of statutory carryforward periods and our experience with operating loss and tax credit carryforward expirations. A history of cumulative losses is a significant piece of negative evidence used in our assessment. If a history of cumulative losses is incurred for a tax jurisdiction, forecasts of future profitability are not used as positive evidence related to the realization of the deferred tax assets in the assessment. We recognize the tax benefits of an uncertain tax position only if those benefits are more likely than not to be sustained based on existing tax law. Additionally, we establish a reserve for tax positions that are more likely than not to be sustained based on existing tax law, but uncertain in the ultimate benefit to be sustained upon examination by the relevant taxing authorities. Unrecognized tax benefits are subsequently recognized at the time the more likely than not recognition threshold is met, the tax matter is effectively settled or the statute of limitations for the relevant taxing authority to examine and challenge the tax position has expired, whichever is earlier. We account for all interest and penalties on uncertain income tax positions as income tax expense. See Note 14, Income Taxes, to the Consolidated Financial Statements for additional information. Earnings Per Share Basic earnings or loss per share is computed by dividing the earnings or loss attributable to common shares by the sum of the weighted average number of shares of common stock outstanding during the period and the weighted average number of stock-based awards that have vested but not yet been issued during the period. Diluted earnings per share reflects the potential dilution of securities that could share in the earnings. Diluted loss per share would be calculated using basic common shares outstanding, as inclusion of potentially dilutive common shares would be anti-dilutive. See Note 15, Earnings Per Share of Common Stock, to the Consolidated Financial Statements for additional information. Cash and Cash Equivalents Cash and cash equivalents include cash on hand and short-term investments that have maturities of three months or less when purchased. The Company has no restricted cash. Receivables We sell the vast majority of our products to select, pre-approved customers using customary trade terms that allow for payment in the future. Customer trade receivables and miscellaneous receivables, net of allowances for current expected credit losses, customer credits and warranties are reported in accounts and notes receivable on a net basis. Cash flows from the collection of receivables are classified as operating cash flows on the Consolidated Statements of Cash Flows. We establish credit-worthiness prior to extending credit. We estimate the net of allowances for current expected credit losses of receivables each period. This estimate is based upon the current and forecasted economic conditions as well as an analysis of prior credit losses by receivable type. Account balances are charged off against the allowance when the potential for recovery is considered remote. We do not have any off-balance-sheet credit exposure related to our customers. See Note 3, Accounts and Notes Receivable, to the Consolidated Financial Statements for additional information. Inventories Inventories are valued at the lower of cost or net realizable value and cost is determined using the FIFO method of accounting. Additionally, inventory balances are adjusted for estimated obsolete or unmarketable inventory equal to the difference between the cost of inventory and its net realizable value. During the fourth quarter of 2021, the Company changed its method of accounting for U.S. based inventories from the LIFO method to the FIFO method. We believe that this change in accounting method is preferable as it results in a better matching of revenue and expense, it more closely resembles the physical flow of inventory, is a more consistent method to value inventory across our businesses, and results in improved comparability with industry peers. See Note 4, Inventories, to the Consolidated Financial Statements for additional information. Property Plant and Equipment Property, plant and equipment is recorded at cost reduced by accumulated depreciation. Depreciation expense is recognized on a straight-line basis over assets’ estimated useful lives. Machinery and equipment includes manufacturing equipment (depreciated over 3 to 15 years), computer equipment (depreciated over 3 to 5 years) and office furniture and equipment (depreciated over 5 to 7 years). Within manufacturing equipment, assets that are subject to accelerated obsolescence or wear, such as tooling and engraving equipment, are depreciated over shorter periods (3 to 7 years). Heavy production equipment, such as conveyors, are depreciated over longer periods (10 to 15 years). Buildings are depreciated over 15 to 30 years, depending on factors such as type of construction and use. Computer software is amortized over 3 to 7 years. Property, plant and equipment is tested for impairment when indicators of impairment exist, such as operating losses and/or negative cash flows. If an evaluation of the undiscounted future cash flows generated by an asset group indicates impairment, the asset group is written down to its estimated fair value, which is based on its discounted future cash flows. The principal assumption used in these impairment tests is future cash flows, which are derived from those used in our operating plan and strategic planning processes. See Note 5, Property, Plant and Equipment, to the Consolidated Financial Statements for additional information. Intangible Assets Our indefinite-lived intangible assets are primarily trademarks which are integral to our corporate identity and expected to contribute indefinitely to our corporate cash flows. We conduct our annual impairment test for indefinite-lived intangible assets during the fourth quarter and we conduct interim impairment tests if indicators of potential impairment exist. An impairment is recognized if the carrying amount of the asset exceeds its fair value. We first perform a qualitative assessment to determine if it is necessary to perform a quantitative impairment test. If a quantitative impairment test is deemed necessary, the method used to determine the fair value of our indefinite-lived intangible assets is the relief-from-royalty method. The principal assumptions used in our application of this method are revenue growth rate, discount rate and royalty rate. Revenue growth rates are derived from those used in our operating plan and strategic planning processes. The discount rate assumption is calculated based upon an estimated weighted average cost of capital, which we believe reflects the overall level of inherent risk and the rate of return a market participant would expect to achieve. The royalty rate assumption represents the estimated contribution of the intangible asset to overall profits. The method used for valuing our indefinite-lived intangible assets did not change from prior periods. Our long-lived intangible assets are primarily contractual arrangements (amortized over 5 years), wh ich includes non-compete agreements, and intellectual property (amortized over 2 to 15 years), which includes developed technology and patents. We review long-lived intangible assets for impairment if indicators of potential impairment exist, such as operating losses and/or negative cash flows. If an evaluation of the undiscounted future cash flows generated by the asset group indicates impairment, the asset group is written down to its estimated fair value, which is based on its discounted future cash flows. The principal assumption used in these impairment tests is future cash flows, which are derived from those used in our operating plan and strategic planning processes. See Note 7, Intangible Assets, to the Consolidated Financial Statements for additional information. Foreign Currency Transactions For our subsidiaries with non-U.S. dollar functional currency, assets and liabilities are translated at period-end exchange rates. Revenues and expenses are translated at exchange rates effective during each month. Foreign currency translation gains or losses are included as a component of AOCI within equity. Gains or losses on foreign currency transactions are recognized through net income (loss). Stock-Based Employee Compensation We issue stock-based compensation to certain employees and non-employee directors in different forms, including various types of performance-based share compensation including PSAs, PSUs, PBRSUs and RSUs. We record stock-based compensation expense based on an estimated grant-date fair value. The expense is reflected as a component of SG&A expenses on our Consolidated Statements of Operations. Stock-based compensation expense includes an estimate for forfeitures and anticipated achievement levels and is generally recognized on a straight-line basis over the vesting period for the entire award. See Note 13, Stock-based Compensation, to the Consolidated Financial Statements for additional information. Leases We lease certain real estate (warehouse and office space), vehicles and equipment. For leases with an initial term of one year or less we recognize lease expense for these leases on a straight-line basis over the lease term. Leases with an initial term of one year or more are recorded on the Consolidated Balance Sheet. We consider all payments fixed unless there is a material impact to the balance sheet at any given time during the lease period. We determine if a contract is a lease at inception. Operating leases are included in operating lease assets, accounts payable and accrued expenses and noncurrent operating lease liabilities in our consolidated balance sheets. Finance leases are included in property and equipment, current installments of long-term debt and long-term debt in our consolidated balance sheets. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we generally use our incremental borrowing rate based on the estimated rate of interest for collateralized borrowing over a similar term of the lease payments at commencement date. We update these rates annually. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain with a compelling economic reason that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. We have elected to combine lease and non-lease components as a single component and account for it as a lease for all asset classes with the exception of land and non-operating buildings. Lease and non-lease components of land and non-operating buildings are generally accounted for separately. We have elected to use a portfolio approach to determine the discount rate and defined portfolio based on the geographic location of the asset by country and duration of the lease. See Note 6, Leases, to the Consolidated Financial Statements for additional information. Recently Adopted Accounting Standards On January 1, 2021, we adopted ASU 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes" This new standard eliminates certain exceptions in the ASC, Section 740, related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period, guidance on accounting for franchise taxes and the recognition of deferred tax liabilities for outside basis differences. It also clarifies and simplifies other aspects of the accounting for income taxes. The adoption of the standard did not have a significant impact on our consolidated financial statements.

Inventory was decreased by $5.3 million and $7.0 million as of December 31, 2021 and 2020, respectively, to reduce inventory to net realizable value as a result of obsolescence. The decrease from 2020 was attributable to the continued implementation of several initiatives aimed at improving the overall composition and age of the Company's inventory.

As a result, the Company has classified amounts outstanding under the Amended ABL Credit Facility and the Amended Term Loan Agreement as Current installments of long-term debt at December 31, 2021 on the Consolidated Balance Sheets. See Note 1, Business and Basis of Presentation, for additional details. During the fourth quarter of 2021, the Company entered into multiple amendments to its Credit Agreements, which further amended the ABL Credit Facility and the Term Loan Agreement. These amendments are described in more detail below. As part of these transactions, the Company recorded a charge of $9.6 million related to the write-off of unamortized debt issuance costs, and debt amendment fees and capitalized $3.7 million in incremental debt issuance costs in accordance with U.S. GAAP. During March 2021, we entered into a new line of credit in China. The new credit limit is $9.3 million with a one-year maturity date and a variable interest rate of 3.85% to 4.35%. The loan is secured by the land and building of our Chinese facility. Amended ABL Credit Facility On June 23, 2020, we entered into an amendment to the ABL Credit Facility, which reduced commitments from $100.0 million to $90.0 million, amended the interest rates applicable to the borrowings, modified certain financial maintenance and other covenants as well as permitted indebtedness under the Term Loan Agreement. This amendment to the ABL Credit Facility provided for a borrowing base that is derived from our accounts receivable and inventory, collectively, with the equity interests in the guarantors, the ABL Priority Collateral, subject to certain reserves and other limitations. On November 1, 2021, the Company entered into the Fourth Amendment to the ABL Credit Facility and on December 31, 2021, the Company entered into the Fifth Amendment to the ABL Credit Facility. These 2021 ABL Amendments amended the interest rates applicable to the Amended ABL Credit Facility, modified certain financial maintenance and other covenants as well as included the consent of the lenders to incur incremental borrowings under the Amended Term Loan Agreement. The Amended ABL Credit Facility permits us to grant a first priority security interest in real estate, machinery and equipment and intellectual property collateral to Term Loan Agent, collectively the Term Loan Priority Collateral. Bank of America, N.A., as administrative agent and collateral agent, will not have a security interest in the real property securing the Amended Term Loan Agreement but will have a second priority security interest in machinery and equipment and intellectual property constituting Term Loan Priority Collateral. In addition, as a result of the 2021 ABL Amendments, the Company has also granted a 100% security in the equity interest of certain foreign subsidiaries. Borrowings under the Amended ABL Credit Facility bear interest at a rate per annum equal to, at our option, a base rate or a Eurodollar rate equal to LIBOR for the relevant interest period, plus, in each case, an applicable margin determined in accordance with the provisions of the 2021 ABL Amendments. The base rate will be the highest of (a) the federal funds rate plus 0.50%; (b) the prime rate of Bank of America, N.A.; and (c) LIBOR plus 1.00%. The applicable margin for borrowings under the Amended ABL Credit Facility will be determined based on the Company’s Consolidated Leverage Ratio (as defined in the 2021 ABL Amendments) and will range from 2.25% to 3.50% with respect to base rate borrowings and 3.25% to 4.50% with respect to Eurodollar rate borrowings. In addition to paying interest on outstanding principal under the Amended ABL Credit Facility, we will pay a commitment fee to the lenders with respect to the unutilized revolving commitments thereunder at a rate ranging from 0.375% to 0.50% depending on the Company’s Consolidated Leverage Ratio (as defined in the 2021 ABL Amendments). The weighted average interest rate for the Amended ABL Credit Facility was 5.74% during 2021. The Amended ABL Credit Facility contains financial covenants applicable to the Company and its subsidiaries. These financial covenants require that the Company and its subsidiaries (i) maintain minimum Availability (as defined in the Amended ABL Credit Facility) of $40 million during the months ending December 31, 2021 and January 31, 2022, $37.5 million during the month ending February 28, 2022, and $25 million thereafter; (ii) maintain minimum Consolidated Cash Flow (as defined in the Amended ABL Credit Facility) for each month, commencing with the month ending December 31, 2021, and calculated on a cumulative basis, ranging from negative $21 million as of December 31, 2021, to negative $40 million as of June 30, 2022; and (iii) maintain a minimum Formula Availability (as defined in the Amended ABL Credit Facility) in an amount ranging from $86.4 million during the month ending December 31, 2021 to $106.4 million during the month ending June 30, 2022. The Company was in compliance with these covenants at December 31, 2021. In addition, the Amended ABL Credit Facility includes certain milestones related to the Company’s consideration of a sale of the Company or other strategic alternatives. These milestones include: (i) a requirement that the Company deliver a confidential information memorandum regarding the sale process to potential buyers, investors and/or refinancing sources by January 14, 2022; (ii) a requirement that the Company provide a summary by February 18, 2022 of all written indications of interest regarding the acquisition of the Company or an alternative transaction that are received on or before that date,; (iii) a requirement that the Company notify by February 28, 2022 whether any binding letter of intent for the acquisition of the Company has been entered into prior to such date and, thereafter, providing copies of any such letter of intent entered into after such date (subject to any necessary redaction); (iv) a requirement that the Company enter into a definitive agreement for the acquisition of the Company by March 31, 2022 which provides for a purchase price in an amount sufficient to repay in full the outstanding loans under the Amended ABL Credit Facility and the Amended Term Loan Agreement and otherwise be in form and substance reasonably satisfactory,; and (v) a requirement that the Company consummate the sale of the Company or a similar transaction by no later than May 15, 2022. As of December 31, 2021, outstanding letters of credit issued under the Amended ABL Credit Facility were $6.8 million and are subject to fees which will be due quarterly in arrears based on the applicable margin described above plus a fronting fee. The total rate for letters of credit was 4.125% as of December 31, 2021. Prior to the 2021 ABL Amendments, the Company had $0.5 million of unamortized deferred financing costs associated with the ABL Credit Facility. In accordance with U.S. GAAP, as a result of the 2021 ABL Amendments, the Company recorded a charge of $0.4 million related to the write-off of unamortized debt issuance costs and capitalized an additional $2.0 million of incremental new debt issuance costs. Amended Term Loan Agreement On June 23, 2020, we entered into the Term Loan Agreement with Pathlight Capital L.P. as the administrative agent. The Term Loan Agreement provided us with secured borrowings of $70.0 million. The borrowing base was derived from the Company’s machinery and equipment, intellectual property and real property, subject to certain reserves and other limitations. The Term Loan Agreement is scheduled to mature on June 23, 2025. During 2021, upon the sale of our South Gate Facility, we made a mandatory prepayment of $20.0 million to Pathlight Capital L.P. towards the principal balance on our Term Loan Agreement as required by the Term Loan Agreement. As part of the mandatory payment, we paid an additional $0.4 million in prepayment premium fees. On November 1, 2021, the Company entered into the First Amendment to the Term Loan Agreement and on December 31, 2021, the Company entered into the Second Amendment to the Term Facility. These 2021 Term Loan Amendments amended the interest rates applicable to the Amended Term Loan Agreement, modified certain financial maintenance and other covenants as well as eliminated scheduled amortization payments. Additionally, the 2021 Term Loan Amendments provided incremental borrowings of $35.0 million. After completion of the 2021 Term Loan Amendments the outstanding aggregate principal under the Amended Term Loan Agreement was $83.3 million. In connection with the 2021 Term Loan Amendments, the Company paid the Term Loan Agent an amendment fee equal to 2.5% of the outstanding principal balance of the original Term Loan Agreement and 5.0% of the incremental borrowings under the Amended Term Loan Agreement. These amendment fees were added to the outstanding principal of the Amended Term Loan Agreement. As a result, total borrowings under the Amended Term Loan Agreement were $86.2 million at December 31, 2021. Under the Amended Term Loan Agreement, borrowings bear interest at LIBOR plus the applicable margin, which was reduced from 12.0% per annum to 11.0% per annum by the 2021 Term Loan Amendments. Interest on amounts outstanding under the original Term Loan Agreement is required to be paid in cash. Interest on the incremental $35.0 million of term loan borrowings under the 2021 Term Loan Amendments will be paid-in-kind and added to the principal balance of Amended Term Loan Agreement. We must use cash proceeds from certain dispositions, including sales of real estate, equity and debt issuances and extraordinary events, to prepay outstanding loans under the Amended Term Loan Agreement, subject to specified exceptions, including the prepayment requirements with respect to the Amended ABL Credit Facility. Additionally, if prepaid within one year amounts outstanding are subject to a prepayment fee equal as defined in the Amended Term Loan Agreement. All obligations under the Amended Term Loan Agreement are guaranteed by each of our wholly owned domestic subsidiaries that individually, or together with its subsidiaries, has assets of more than $1.0 million and are secured by a first priority lien on the Term Priority Collateral and a second priority lien on the ABL Priority Collateral. Also under the terms of the 2021 Term Loan Amendments, the Company’s Australian subsidiary granted a security interest in its real and personal property to the Term Loan Agent, which is included in the term loan borrowing base. The Amended Term Loan Agreement contains a number of covenants that, among other things, and subject to certain exceptions, restrict our ability to create liens, to undertake fundamental changes, to incur debt, to sell or dispose of assets, to make investments, to make restricted payments such as dividends, distributions or equity repurchases, to change the nature of our businesses, to enter into transactions with affiliates and to enter into certain burdensome agreements. At December 31, 2021, we were in compliance with these debt covenants. In addition, the Amended Term Loan Agreement requires us to comply with the Amended ABL Credit Facility financial covenants. The Amended Term Loan Agreement also contains customary affirmative covenants and events of default, including a cross-default provision in respect of certain material indebtedness and a change of control provision. If an event of default occurs, the lenders may choose to accelerate the maturity of the Amended Term Loan Agreement and require repayment of all obligations thereunder. Prior to the 2021 Term Loan Amendments, the Company had $5.5 million of unamortized deferred financing costs associated with the Term Loan Agreement. In accordance with U.S. GAAP, as a result of the 2021 Term Loan Amendments, the Company recorded a charge of $5.5 million related to the write-off of unamortized debt issuance costs and capitalized an additional $1.7 million of incremental new debt issuance costs. The Company also incurred $3.7 million of debt amendment fees which were not capitalized.

Retirement Benefits [Abstract]
Pension and Other Postretirement Benefit Programs	PENSION AND OTHER POSTRETIREMENT BENEFIT PROGRAMS We have defined-benefit pension and other postretirement benefit plans covering eligible employees in North America. Benefits from defined-benefit pension plans are based primarily on years of service. We fund our pension plans when appropriate. We fund postretirement benefits on a pay-as-you-go basis, with the retiree paying a portion of the cost for health care benefits by means of deductibles and contributions. During 2020, the Company approved two plan changes. One of our U.S. defined-benefit pension plans, the RIP, was amended as of December 31, 2020, to freeze the accrual of additional benefits for the Company's non-union production employees and Lancaster International Association of Machinists and Aerospace Workers participants. Also, our U.S. postretirement plan’s life insurance benefit is no longer being offered for hourly participants at various locations (Beech Creek, Kankakee, and Stillwater) and for traditional salaried participants who retire on or after January 1, 2021. We also have defined contribution plans providing for the Company to contribute a specified matching amount for participating employees’ contributions to the plan. The matching amount is dependent upon employee classification, but is generally either a 50% match on the first 6% of pay contributed with a maximum company matching contribution of 3% or a 100% match on the first 4% of pay contributed plus 50% match on the next 4% of pay contributed with a maximum company matching contribution of 6%. Participants become vested in the Company’s matching amount when they have completed three calendar years of company service and worked at least 1,000 hours in each year. Costs for defined-contribution plans were $6.6 million and $3.6 million in 2021 and 2020, respectively. Costs during 2020 were lower due to the temporary suspension of Company contribution from May 2020 through September 2020 as a countermeasure to the impact of the COVID-19 pandemic. Defined-Benefit Pension Plans The following tables summarize the balance sheet impact of the pension benefit plans, as well as the related benefit obligations, assets, funded status and rate assumptions. The pension benefits disclosures include both the qualified, funded RIP and the Retirement Benefit Equity Plan, which is a non-qualified, unfunded plan designed to provide pension benefits in excess of the limits defined under Sections 415 and 401(a)(17) of the Internal Revenue Code. The disclosures also include our two Canadian pension plans. U.S. Pension Plans Canadian Pension Plans 2021 2020 2021 2020 Change in benefit obligation: Projected benefit obligations as of January 1 $ 418.4 $ 394.6 $ 17.1 $ 16.3 Service cost 1.0 2.6 — — Interest cost 10.2 12.5 0.4 0.5 Foreign currency translation adjustment — — 0.1 0.4 Effect of plan curtailment — (0.9) (0.6) — Actuarial (gain) loss (13.6) 30.4 (1.1) 1.2 Benefits paid (21.6) (20.8) (1.3) (1.3) Projected benefit obligations as of December 31 394.4 418.4 14.6 17.1 Change in plan assets: Fair value of plan assets as of January 1 417.2 380.7 14.8 14.2 Actual return on plan assets 19.5 57.2 0.6 1.4 Employer contribution 0.1 0.1 0.1 0.1 Foreign currency translation adjustment — — 0.1 0.4 Effect of plan settlements — — (0.6) — Benefits paid (21.6) (20.8) (1.4) (1.3) Fair value of plan assets as of December 31 415.2 417.2 13.6 14.8 Funded status of the plans $ 20.8 $ (1.2) $ (1.0) $ (2.3) Accumulated benefit obligation as of December 31 $ 394.4 $ 418.4 $ 14.6 $ 17.1 Actuarial gains related to the change in the benefit obligation for the U.S. and Canadian pension plans for the year ended December 31, 2021 was primarily due to an increase in discount rate, and an experience gain due to plan experience for the Canadian pension plans. A ctuarial losses related to the change in benefit obligation for U.S. and Canadian pension plans for the year ended December 31, 2020 were primarily due to the decrease in the discount rate each period. The table below presents the weighted-average assumptions used in computing the benefit obligations and net periodic benefit cost for the defined-benefit pension plans: U.S. Pension Plans Canadian Pension Plans 2021 2020 2021 2020 Weighted average assumptions used to determine benefit obligations as of December 31: Discount rate 2.85 % 2.50 % 2.80 % 2.30 % Rate of compensation increase 3.25 % 3.25 % n/a n/a Weighted average assumptions used to determine net periodic benefit cost for the period: Discount rate 2.50 % 3.25 % 2.30 % 3.00 % Expected return on plan assets 5.25 % 5.70 % 3.60 % 4.00 % Rate of compensation increase 3.25 % 3.25 % n/a n/a Basis of Rate-of-Return Assumption Long-term asset class return assumptions are determined based on the expected performance of the asset classes over 20 years. For the U.S. plans, these forecasted gross returns were reduced by estimated management fees and expenses, yielding a long-term return forecast of 5.25% and 5.70% for the years ended December 31, 2021 and 2020, respectively. For our Canadian plans, these forecasted gross returns were reduced by estimated management fees and expenses, yielding a long-term return forecast of 3.60% and 4.00% for the years ended December 31, 2021 and 2020, respectively. Defined-benefit pension plans with benefit obligations in excess of plan assets were as follows: U.S. Pension Plans Canadian Pension Plans 2021 2020 2021 2020 Projected benefit obligation, December 31 $ 2.2 $ 2.3 $ 14.6 $ 16.7 Accumulated benefit obligation, December 31 2.2 2.3 14.6 16.7 Fair value of plan assets, December 31 — — 13.5 14.4 The U.S. pension plans had a prepaid asset balance of $23.0 million and $1.1 million at December 31, 2021 and 2020, respectively. The components of net periodic pension cost for the U.S. and Canadian defined-benefit pension plans were as follows: Year Ended December 31, U.S. Pension Plans Canadian Pension Plans 2021 2020 2019 2021 2020 2019 Service cost of benefits earned during the period $ 1.0 $ 2.6 $ 2.7 $ — $ — $ — Interest cost on projected benefit obligation 10.2 12.5 15.0 0.4 0.5 0.6 Expected return on plan assets (21.2) (21.3) (21.7) (0.5) (0.5) (0.7) Recognized net actuarial loss 3.0 10.1 9.7 0.2 0.3 0.4 Net periodic pension cost $ (7.0) $ 3.9 $ 5.7 $ 0.1 $ 0.3 $ 0.3 Excluded from net periodic pensions costs in the Canadian pension plans table above were $0.6 million of settlement gains recorded in 2021. Investment Policies Our primary investment objective is to maintain the funded status of the plans such that the likelihood that we will be required to make significant contributions to the plan is limited. This objective is expected to be achieved by: • Investing a substantial portion of the plan assets in high quality corporate and treasury bonds whose duration is at least equal to that of the plan’s liabilities such that there is a relatively high correlation between the movements of the plan’s liability and asset values. • Investing in publicly traded equities in order to increase the ratio of plan assets to liabilities over time. • Limiting investment return volatility by diversifying among additional asset classes with differing expected rates of return and return correlations. Each asset class used has a defined asset allocation target and allowable range. The tables below show the asset allocation targets and the December 31, 2021 and 2020 positions for each asset class: Target Weight at Position at December 31, December 31, 2021 2021 2020 U.S. Asset Class Fixed income securities 65 % 62 % 54 % Equities 35 % 38 % 46 % Canadian Asset Class Fixed income securities 50 % 50 % 50 % Equities 48 % 48 % 48 % Other 2 % 2 % 2 % The change in the U.S. defined benefit pension plan asset allocation for the year ended December 31, 2021 is due to a reduction in return seeking assets to minimize risk for the portfolio and further protect the overall funded status. Pension plan assets are required to be reported and disclosed at fair value in the financial statements. 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 on 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. 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 asset’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs. The following tables set forth by level within the fair value hierarchy a summary of the U.S. and Canadian defined-benefit pension plan assets, net of payables for administrative expenses, measured at fair value on a recurring basis: Value at December 31, 2021 Level 1 Level 2 Level 3 Total U.S. Plans Fixed income securities $ — $ 258.5 $ — $ 258.5 Equities — 156.8 — 156.8 Other (0.1) — — (0.1) Net assets measured at fair value $ (0.1) $ 415.3 $ — $ 415.2 Value at December 31, 2020 Level 1 Level 2 Level 3 Total U.S. Plans Fixed income securities $ — $ 226.5 $ — $ 226.5 Equities — 191.0 — 191.0 Other (0.3) — — (0.3) Net assets measured at fair value $ (0.3) $ 417.5 $ — 417.2 Value at December 31, 2021 Level 1 Level 2 Level 3 Total Canadian Plans Fixed income securities $ — $ 6.7 $ — $ 6.7 Equities — 6.6 — 6.6 Other 0.3 — — 0.3 Net assets measured at fair value $ 0.3 $ 13.3 $ — $ 13.6 Value at December 31, 2020 Level 1 Level 2 Level 3 Total Canadian Plans Fixed income securities $ — $ 7.5 $ — $ 7.5 Equities — 7.1 — 7.1 Other 0.2 — — 0.2 Net assets measured at fair value $ 0.2 $ 14.6 $ — $ 14.8 Following is a description of the valuation methodologies used for assets. Fixed income securities - Consists of registered investment funds, common trust funds, collective trust funds and segregated funds investing in fixed income securities tailored to institutional investors. The fair values of the investments in this class are based on the underlying securities in each fund’s portfolio, which is the amount the fund would receive for the security upon a current sale. Equities - Consists of investments in funds investing in equities tailored to institutional investors. The fair value of each fund is based on the underlying securities in each fund’s portfolio, which is the amount the fund would receive for the security upon a current sale. Other - Consists of cash and cash equivalents and other payables and receivables (net). The carrying amounts of cash and cash equivalents approximate fair value due to the short-term maturity of these instruments. The carrying amounts of payables and receivables approximate fair value due to the short-term nature of these instruments. Defined-Benefit Postretirement Benefit Plans The following tables summarize the balance sheet impact of the postretirement benefit plans, as well as the related benefit obligations, assets, funded status and rate assumptions. 2021 2020 Change in benefit obligation: Projected benefit obligations as January 1 $ 59.6 $ 65.3 Service cost — — Interest cost 1.3 1.9 Plan participants' contributions 0.7 1.2 Plan amendments — (6.4) Actuarial (gain) loss (6.2) 4.5 Benefits paid (3.7) (6.9) Projected benefit obligation as of December 31 51.7 59.6 Change in plan assets: Fair value of plan assets as January 1 — — Employer contribution 3.0 5.7 Plan participants' contribution 0.7 1.2 Benefits paid (3.7) (6.9) Fair value of plan assets as of December 31 — — Funded status of the plans $ (51.7) $ (59.6) The actuarial gains related to the change in benefit obligation for the obligation for the postretirement benefit plans for the year ended December 31, 2021 was primarily due to the increase in the discount rate and an experience gain due to plan experience. The actuarial loss related to the change in benefit obligation for the postretirement plans for the year ended December 31, 2020 was primarily due to the decrease in the discount rate and new claim costs being higher than assumed, partially offset by a gain from the census data updates. The table below presents the weighted-average assumptions used in computing the benefit obligations and net periodic benefit cost for the U.S. defined-benefit postretirement benefit plans: 2021 2020 Weighted average discount rate used to determine benefit obligations as of December 31 2.80 % 2.45 % Weighted average discount rate used to determine net periodic benefit cost 2.45 % 3.20 % The components of net periodic postretirement (benefit) cost were as follows: Year Ended December 31, 2021 2020 2019 Service cost of benefits earned during the period $ — $ — $ 0.2 Interest cost on accumulated postretirement benefit obligations 1.3 1.9 2.5 Amortization of prior service (credit) (1.1) (0.2) — Amortization of net actuarial (gain) (1.3) (4.8) (3.1) Net periodic postretirement (benefit) cost $ (1.1) $ (3.1) $ (0.4) As a result of the elimination of future life insurance benefits for certain employees, we recorded a curtailment gain of $1.8 million in 2020 in other income. This gain is not reflected in the above table. For measurement purposes, an average rate of annual increase in the per capita cost of covered health care benefits of 6.5% for pre-65 retirees was assumed for 2022, decreasing ratably to an ultimate rate of 4.5% by 2029. Financial Statement Impacts Amounts recognized in assets and (liabilities) on the Consolidated Balance Sheets at year end consist of: U.S. Pension Benefits Canadian Pension Benefits Postretirement Benefits 2021 2020 2021 2020 2021 2020 Prepaid pension asset $ 23.0 $ 1.1 $ — $ — $ — $ — Accrued payroll and employee costs — — — — (3.5) (4.0) Postretirement benefit liabilities — — — — (48.2) (55.6) Pension benefit liabilities (2.2) (2.3) (1.0) (2.3) — — Net amount recognized $ 20.8 $ (1.2) $ (1.0) $ (2.3) $ (51.7) $ (59.6) Pre-tax amounts recognized in AOCI at year end for our pension and postretirement benefit plans consist of: U.S. Pension Benefits Canadian Pension Benefits Postretirement Benefits 2021 2020 2021 2020 2021 2020 Net actuarial gain (loss) $ (91.7) $ (106.7) $ (3.4) $ (4.9) $ 29.5 $ 25.6 We expect to contribute $0.1 million and $0.3 million to our U.S. and Canadian defined-benefit pension plans, respectively, and $3.5 million to our U.S. postretirement benefit plans in 2022. Future Benefit Payments The following benefit payments, which reflect expected future service, as appropriate, are expected to be paid over the next ten years for our U.S. and Canadian plans: U.S. Pension Benefits Canadian Pension Benefits Postretirement Benefits 2022 $ 21.4 $ 1.3 $ 3.5 2023 21.9 1.2 3.4 2024 22.0 1.2 3.2 2025 22.1 1.1 3.1 2026 23.1 1.1 3.0 2027-2031 114.2 4.8 14.3 These estimated benefit payments are based on assumptions about future events. Actual benefit payments may vary significantly from these estimates.

Commitments and Contingencies Disclosure [Abstract]
Litigation And Related Matters	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 In connection with our current or legacy manufacturing operations, or those of former owners, we may from time to time become involved in the investigation, closure and/or remediation of existing or potential environmental contamination under the Comprehensive Environmental Response, Compensation and Liability Act as well as state or international Superfund and similar type environmental laws. For those matters, we may have rights of contribution or reimbursement from other parties or coverage under applicable insurance policies; however, we cannot predict with certainty the future identification of or expenditure for any investigation, closure or remediation of any environmental site. Summary of Financial Position There were no material liabilities recorded as of December 31, 2021 and December 31, 2020 for potential environmental liabilities that we consider probable and for which a reasonable estimate of the probable liability could be made. Other Claims We are involved in various lawsuits, claims, investigations and other legal matters from time to time that arise in the ordinary course of conducting business, including matters involving our products, intellectual property, relationships with suppliers, relationships with distributors and relationships with competitors, employees and other matters. For example, we are currently a party to various litigation matters that involve product liability, tort liability and other claims under a wide range of 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. In some cases, these allegations involve multiple defendants and relate to legacy products that we and other defendants purportedly manufactured or sold. We believe these claims and allegations to be 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. While complete assurance cannot be given to the outcome of these proceedings, we do not believe that any of these matters, individually or in the aggregate, will have a material adverse effect on our financial condition, results of operations or cash flows. On November 15, 2019, a shareholder filed a putative class action complaint in the United States District Court for the Central District of California alleging violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5, promulgated thereunder, based on alleged false and/or misleading statements or omissions made between March 6, 2018 and November 4, 2019. On November 30, 2020, the Company reached a settlement in principle to fully resolve this matter. The settlement agreement provided, in part, for a settlement payment of $3.75 million in exchange for the dismissal and a release of all claims against the defendants. Neither the Company nor any individual defendant admits any wrongdoing through the settlement agreement. In September 2021, the $3.75 million settlement payment was paid by our insurance provider under our relevant insurance policy and placed into escrow for distribution. The Company had previously recorded the settlement in the caption Accounts and notes receivable, net and Other accrued expenses on the Consolidated Balance Sheets.

Stock-Based Compensation

Stock-Based Compensation	12 Months Ended

Share-based Payment Arrangement [Abstract]
Stock-Based Compensation	STOCK-BASED COMPENSATION In April 2016, AFI adopted the Armstrong Flooring, Inc. 2016 LTI Plan and the Armstrong Flooring, Inc. 2016 Directors' Plan, which collectively comprised a new compensation program that allows for the grant of stock-based compensation awards to certain employees and non-employee directors of AFI different forms of benefits, including performance-based awards and RSUs. On June 2, 2017, our stockholders approved an amendment and restatement of the 2016 LTI Plan. On June 4, 2021, our stockholders approved an amendment and restatement of the 2016 Directors' Plan. Under the 2016 LTI Plan, as amended, our Board has authorized up to 7,600,000 shares of common stock for issuance. Our Board authorized up to 900,000 shares of common stock that may be issued pursuant to the 2016 Directors' Plan, as amended. As of December 31, 2021, 964,475 shares and 198,179 shares were available for future grants under the 2016 LTI Plan and the 2016 Directors' Plan as amended, respectively. Prior to the Spin-off, AWI issued stock-based compensation awards to employees and directors that became employees or directors of AFI. In connection with the Spin-off, these awards were converted into new AFI equity awards using a formula designed to preserve the intrinsic value of the awards immediately prior to the Spin-off. The modification did not result in a change to the value of the awards. The terms and conditions of the AWI awards were replicated and, as necessary, adjusted to ensure that the vesting schedule and economic value of the awards was unchanged by the conversion. At December 31, 2021 only stock option awards remained outstanding related to AWI issued stock-based compensation awards. Stock-based compensation expense Stock-based compensation expense is generally recognized on a straight-line basis over the vesting period and is recorded as a component of SG&A. Total stock-based compensation expense included in the Consolidated Statements of Operations and the related tax effects are presented in the table below: Year Ended December 31, 2021 2020 2019 Stock-based compensation expense $ 3.0 $ 2.7 $ 1.2 Income tax benefit — — — To the extent that the vesting-date fair value of an award is greater than the grant-date fair value, the excess tax benefit is recorded as an income tax benefit in the Consolidated Statements of Operations. For the year ended December 31, 2021 there was no income tax expense related to vested stock-based compensation awards. For the years ended December 31, 2020 and 2019 the income tax expense was $0.3 million and $0.1 million, respectively, related to vested stock-based compensation awards. As of December 31, 2021, $4.5 million of total unrecognized compensation expense related to non-vested stock-based compensation arrangements is expected to be recognized over a weighted-average period of 2.2 years. Performance-based stock compensation The Company grants PSAs, PSUs and PBRSUs to key executive employees and certain management employees of AFI under the 2016 LTI Plan. These awards represent units of restricted Company common stock that vest based on the achievement of certain performance or market conditions. PSAs and PSUs - The performance condition for 75% of the awards is based on earnings before interest, taxes, depreciation and amortization. The performance condition for the remaining 25% of the awards is based on cumulative free cash flow, defined as cash flow from operations, less cash used in investing activities. PSAs issued to key executive employees are also indexed to the achievement of specified levels of absolute total shareholder return and the fair value was measured using a Monte-Carlo simulation on the date of grant. For PSUs that are not indexed to the achievement of specified levels of absolute total shareholder return, the fair value was measured using our stock price on the date of grant. If the performance conditions are met, the awards vest at the conclusion of the performance period, which is generally at the end of the third fiscal year following the date of grant. We did not issue any PSAs during 2021, 2020 or 2019 and did not issue any PSUs during 2021 or 2020. Details of PSUs issued during 2019 are as follows: 2019 Issued (in thousands) 200.9 Weighted-average grant date fair value $ 13.25 PBRSUs - The Company issued 592,213 PBRSUs to key executive employees and certain management employees on April 1, 2021. The market condition is based on price targets for the Company's common stock at a future date. Price targets are achieved if the average closing sale stock price of one share of Company Stock, over the 20 trading days following the date of the 2023 year-end earnings release, equals or surpasses the price targets. The number of shares earned is based upon the achievement of four stock price hurdles: $7.25, $8.75, $10.25 and $11.75. Following the first price target achievement, 50% of the overall performance units are earned. With each of the next three Price Target Achievements, an additional 25% of the overall performance units are earned. Payout percentages will be linearly interpolated for stock price performance between the hurdles. The Monte-Carlo valuation provided a weighted average fair value of $4.37 per share for the grant-date fair value. The Company issued 691,130 PBRSUs to key executive employees and certain management employees on March 24, 2020. The market condition is based on price targets for the Company's common stock at a future date. Price targets are achieved if the average closing sale stock price of one share of Company Stock, over the 20 trading days following the date of the 2022 year-end earnings release, equals or surpasses the price targets. The number of shares earned is based upon the achievement of four stock price hurdles: $6.00, $7.50, $9.00 and $10.50. Following the first price target achievement, 50% of the overall performance units are earned. With each of the next three Price Target Achievements, an additional 25% of the overall performance units are earned. Payout percentages will be linearly interpolated for stock price performance between the hurdles. The Monte-Carlo valuation provided a weighted average fair value of $0.90 per share for the grant-date fair value. The Company issued 371,430 PBRSUs to the CEO on September 11, 2019. The market condition is based on price targets for the Company's common stock at a future date. The number of shares earned is based upon the achievement of five stock price hurdles over the period from September 11, 2019 through September 11, 2024. The five per share stock price hurdles are $10.50, $12.25, $14.00, $15.75 and $17.50. A Monte-Carlo valuation was performed to simulate possible future stock prices for AFI over the time remaining period of the award. The Monte-Carlo valuation provided a fair value for each of the five per share stock price hurdles discussed above, respectively: $5.93, $5.28, $4.70, $4.20 and $3.75 (weighted average value of $4.77); and provided derived service periods of 3 years for the first two hurdles and 4 years for the remaining three hurdles. The following table summarizes the Monte-Carlo inputs and grant-date fair value price used for PBRSU issuances. April 1, March 24, September 11, Grant-date stock price (AFI closing stock price on date of grant) $ 5.20 $ 2.18 $ 7.43 Assumptions Risk-free rate of return 0.35 % 0.44 % 1.59 % Expected volatility 88.53 % 66.29 % 41.45 % Expected dividend yield — — — The risk-free rate of return was determined based on the implied yield available on zero-coupon U.S. Treasury bills at the time of grant with a remaining term equal the expected term of the award. The expected volatility was based on a weighted average of the volatility of AFI and (or) the average volatility of our compensation peer group's volatility. The expected dividend yield was assumed to be zero because, at the time of the grant, we had no plans to declare a dividend. The table below summarizes activity related to the PSUs and PBRSUs.

The RSUs are units representing shares of Company common stock which are converted to shares of Company common stock at the end of the service period. There are no performance or market conditions associated with these awards. For awards issued prior to 2020, vesting generally occurs with one third of the awards vesting at the end of one, two and three years from the date of grant. In 2020, most newly issued RSUs cliff vest three years from the date of grant. The fair value of RSUs was measured using our stock price on the date of grant. Details of RSUs issued during 2021, 2020 and 2019 are as follows: 2021 2020 2019 Issued (in thousands) 137.3 165.0 622.8 Weighted-average grant date fair value 5.2 4.36 7.39 The table below summarizes activity related to RSUs.

These relate to employees in certain international jurisdictions which have prohibitions related to stock settled awards. Director Awards - RSUs were granted to our non-employee directors under the 2016 Directors' Plan, as amended. These awards generally have a vesting period of one year and any dividends paid prior to vesting are forfeitable if the award does not vest. The awards are generally payable six months following the director’s separation from service on the Board.

Income Taxes	INCOME TAXES The following table presents income (loss) from continuing operations before income taxes for U.S. and international operations based on the location of the entity to which such earnings or losses are attributable: Year Ended December 31, 2021 2020 2019 Domestic $ (56.0) $ (65.0) $ (63.9) Foreign 2.5 1.1 (1.7) Total $ (53.5) $ (63.9) $ (65.6) The following table presents the components of the income tax expense (benefit): Year Ended December 31, 2021 2020 2019 Current Federal $ 0.3 $ 0.2 $ 0.3 Foreign 0.7 0.7 0.4 State and local 0.1 0.1 0.1 Subtotal 1.1 1.0 0.8 Deferred Federal (0.6) (2.5) 0.1 Foreign (0.5) 1.1 0.6 State and local (0.5) (0.4) 0.1 Subtotal (1.6) (1.8) 0.8 Total $ (0.5) $ (0.8) $ 1.6 As of December 31, 2021, we reviewed our position with regard to foreign unremitted earnings and determined that unremitted earnings would continue to be permanently reinvested. Accordingly, we have not recorded income taxes on approximately $18 million of undistributed earnings of foreign subsidiaries that could be subject to taxation if remitted to the U.S. because we currently plan to keep these amounts permanently invested overseas. It is not practicable to calculate the residual income tax that would result if these basis differences reversed due to the complexities of the tax law and the hypothetical nature of the calculations. The following table presents the differences between our income tax benefit at the U.S. federal statutory income tax rate and our effective income tax rate: Year Ended December 31, 2021 2020 2019 Continuing operations tax at statutory rate $ (11.2) $ (13.4) $ (13.7) Increase in valuation allowances on deferred federal income tax assets 10.2 10.3 13.9 Increase in valuation allowances on deferred state income tax assets 1.4 2.6 2.1 State income tax benefit, net of federal benefit (1.7) (2.7) (1.8) Tax on foreign and foreign-source income 3.0 0.5 1.2 Permanent book/tax differences 0.5 0.6 1.1 Increase (decrease) in valuation allowances on deferred foreign income tax assets (2.5) 1.3 0.1 Other (0.2) — (1.3) Total $ (0.5) $ (0.8) $ 1.6 The tax effects of principal temporary differences between the carrying amounts of assets and liabilities and their tax bases are summarized in the following table. Management believes it is more likely than not that the results of future operations will generate sufficient taxable income in the appropriate jurisdiction and foreign source income to realize deferred tax assets, net of valuation allowances. In arriving at this conclusion, we considered the profit or loss before tax generated for the years 2019 through 2021, as well as future reversals of existing taxable temporary differences and projections of future profit before tax. December 31, 2021 December 31, 2020 Deferred income tax assets (liabilities) Postretirement and postemployment benefits $ 13.4 $ 15.8 Net operating losses 36.6 38.1 Accrued expenses 4.4 5.0 Deferred compensation 3.9 3.2 Customer claims reserves 5.1 4.3 Goodwill 1.9 2.1 Pension benefit liabilities — 0.3 Tax credit carryforwards 2.6 2.5 Intangibles 4.9 3.8 163(j) Disqualified Interest 6.2 2.3 Other 5.0 2.4 Total deferred income tax assets 84.0 79.8 Valuation allowances (51.6) (47.2) Net deferred income tax assets 32.4 32.6 Accumulated depreciation (16.1) (20.7) Inventories (3.3) (7.4) Pension benefit asset (5.3) — Other (4.6) (2.5) Total deferred income tax liabilities (29.3) (30.6) Net deferred income tax assets $ 3.1 $ 2.0 Deferred income taxes have been classified in the Consolidated Balance Sheet as: Deferred income tax assets—noncurrent $ 4.2 $ 4.4 Deferred income tax liabilities—noncurrent (1.1) (2.4) Net deferred income tax assets $ 3.1 $ 2.0 We reduce the carrying amounts of deferred tax assets by a valuation allowance if, based on the available evidence, it is more likely than not that such assets will not be realized. The need to establish valuation allowances for deferred tax assets is assessed quarterly. In assessing the requirement for, and amount of, a valuation allowance in accordance with the more likely than not standard for all periods, we give appropriate consideration to all positive and negative evidence related to the realization of the deferred tax assets. This assessment considers, among other matters, the nature, frequency and severity of current and cumulative losses, forecasts of future profitability, the duration of statutory carryforward periods and our experience with operating loss and tax credit carryforward expirations. A history of cumulative losses is a significant piece of negative evidence used in our assessment. If a history of cumulative losses is incurred for a tax jurisdiction, forecasts of future profitability are not used as positive evidence related to the realization of the deferred tax assets in the assessment. The following table presents the components of our valuation allowance against deferred income tax assets: Year Ended December 31, 2021 2020 Federal $ 38.3 $ 32.0 State 8.4 7.8 Foreign 4.9 7.4 Total $ 51.6 $ 47.2 The valuation allowances offset federal, state and foreign deferred tax assets, credits and operating loss carryforwards. The following is a summary of our NOL carryforwards: Year Ended December 31, 2021 2020 Federal $ 124.4 $ 124.1 State 104.7 103.0 Foreign 19.1 28.1 As of December 31, 2021, $75.0 million of state NOL carryforwards expire between 2022 and 2041; and $19.1 million foreign NOL carryforwards expire between 2022 and 2026. The remainder are available for carryforward indefinitely. We estimate we will need to generate future taxable income of approximately $192.2 million for state income tax purposes during the respective realization periods (ranging from 2022 to 2041) in order to fully realize the net deferred income tax assets discussed above. We have $1.3 million of UTBs as of December 31, 2021. None of this amount, if recognized in future periods, would impact the reported effective tax rate. It is reasonably possible that certain UTBs may increase or decrease within the next twelve months due to tax examination changes, settlement activities, expirations of statute of limitations, or the impact on recognition and measurement considerations related to the results of published tax cases or other similar activities. Over the next twelve months, we estimate no UTBs decreases related to state statutes expiring. The following table presents a reconciliation of the total amounts of UTBs, excluding interest and penalties: 2021 2020 2019 Unrecognized tax benefits as of January 1 $ 1.3 $ 0.7 $ 1.6 Increase for prior period positions — 0.7 — Decreases for prior period positions — — (0.9) Decrease due to statute expirations — (0.1) — Unrecognized tax benefits balance as of December 31 $ 1.3 $ 1.3 $ 0.7 We conduct business globally, and as a result, we file income tax returns in the U.S., various states and international jurisdictions. In the normal course of business, we are subject to examination by taxing authorities throughout the world in such major jurisdictions as Australia, Canada, China and the U.S. Generally, we have open tax years subject to tax audit on average of between three years and six years. With few exceptions, the statute of limitations is no longer open for state or non-U.S. income tax examinations for the years before 2014. We have not significantly extended any open statutes of limitation for any major jurisdiction and have reviewed and accrued for, where necessary, tax liabilities for open periods. The tax years 2014 through 2020 are subject to future potential tax adjustments.

Shareholders' Equity	STOCKHOLDERS' EQUITY Common Stock Repurchase Plan On March 6, 2017, we announced that our Board had approved a share repurchase program pursuant to which we were authorized to repurchase up to $50.0 million of our outstanding shares of common stock. From inception of the share repurchase program through May 3, 2019, we repurchased approximately 2.5 million shares for a total cost of $41.0 million, with an average price of $16.23 per share. On May 3, 2019, we announced that our Board had authorized an increased share repurchase program for an additional $50.0 million beyond the $41.0 million already repurchased under the prior share repurchase program, effective immediately. Repurchases under the new program could be made through open market, block and privately negotiated transactions, including Rule 10b5-1 plans, at times and in such amounts as management deemed appropriate, subject to market and business conditions, regulatory requirements and other factors. On May 17, 2019, we announced the commencement of a modified "Dutch auction" self-tender offer to repurchase up to $50.0 million in cash of shares of our common stock. As a result of the auction, on June 21, 2019 we purchased 4,504,504 shares of common stock at a purchase price of $11.42 per share, for a total cost of $51.4 million , including fees and expenses. After the completion of the tender offer, we have no remaining authorization to purchase further shares.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Consolidation Policy	Consolidation Policy The Consolidated Financial Statements and accompanying data in this Form 10-K include the accounts of AFI and its subsidiaries. Intercompany accounts and transactions have been eliminated from the Consolidated Financial Statements.
Changes in Accounting Principle	Change in Accounting PrincipleDuring the fourth quarter of 2021, the Company changed its method of accounting for U.S. based inventories from the LIFO method to the FIFO method. We believe that this change in accounting method is preferable as it results in a better matching of revenue and expense, it more closely resembles the physical flow of inventory, is a more consistent method to value inventory across our businesses, and results in improved comparability with industry peers. The effects of this change have been retroactively applied to all periods presented. This change resulted in a decrease to accumulated deficit of $3.0 million as of January 1, 2019.
Use of Estimates	Use of Estimates We prepare our financial statements in conformity with U.S. GAAP, which requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets, liabilities, revenues and expenses. When preparing an estimate, management determines the amount based upon the consideration of relevant internal and external information. Actual results may differ from these estimates.
Revenue Recognition	Revenue Recognition We recognize revenue when control of the promised goods is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods. Our primary performance obligation to our customers is the delivery of flooring products pursuant to purchase orders. Control of the products we sell generally transfers to our customers at the point in time when the goods are shipped. Our standard sales terms are primarily free-on-board shipping point. Our typical payment terms are 30 days and our sales arrangements do not contain any significant financing component for our customers. Our customer arrangements do not generate contract assets or liabilities that are material to the Consolidated Financial Statements. Each purchase order sets forth the transaction price for the products purchased under that arrangement. Some customer arrangements include variable consideration, such as volume rebates, some of which depend upon our customers meeting specified performance criteria, such as a purchasing level over a period of time. We use judgment to estimate the most likely amount of variable consideration at each reporting date. Costs to obtain a contract are capitalized and amortized over the life of the related contract when the incremental costs directly relate to a specific contract, generates or enhances resources of the company that will be used to satisfy performance of the terms of the contract and the cost are expected to be recovered from the customer. During the fourth quarter of 2020 we capitalized $1.1 million of costs to obtain a contract, related to a single new arrangement, which will be amortized over the three We disaggregate revenue based on customer geography as this category represents the most appropriate depiction of how the nature, timing and uncertainty of revenues and cash flows are impacted by economic factors. See Note 12, Revenue, to the Consolidated Financial Statements for our revenues disaggregated by geography. Warranties - We provide our customers with a product warranty that provides assurance that the products we sell meet standard specifications and are free of defects. We maintain a reserve for claims and related costs based on historical experience and periodically adjusts these provisions to reflect actual experience. See Note 3, Accounts and Notes Receivable, to the Consolidated Financial Statements for additional information. Sales Incentives - Sales incentives to customers are reflected as a reduction of net sales. Shipping and Handling Costs - We treat shipping and handling that occurs after customers obtain control of the products as a fulfillment activity and not as a promised service. Shipping and handling costs are reflected as a component of Cost of goods sold. Taxes - Taxes collected from customers and remitted to governmental authorities are reported on a net basis.
Advertising Costs	Advertising Costs
Pension and Postretirement Benefits	Pension and Postretirement Benefits We have benefit plans that provide for pension, medical and life insurance benefits to certain eligible employees when they retire from active service. The cost of plan amendments that provide for benefits already earned by plan participants is amortized over the expected future working lifetime or the life expectancy of plan participants. A market-related value of plan assets methodology is utilized in the calculation of expected return on assets. The methodology recognizes gains and losses on long duration bonds immediately, while gains and losses on other assets are recognized in the calculation over a five-year period. We use a December 31 measurement date for our pension and postretirement benefit plans. See Note 9, Pension and Other Postretirement Benefit Programs, to the Consolidated Financial Statements for additional information.
Taxes	Taxes The provision for income taxes has been determined using the asset and liability approach of accounting for income taxes to reflect the expected future tax consequences of events recognized in the Consolidated Financial Statements. Deferred income tax assets and liabilities are recognized by applying enacted tax rates to temporary differences that exist as of the balance sheet date which result from differences in the timing of reported taxable income between tax and financial reporting. We reduce the carrying amounts of deferred tax assets by a valuation allowance if, based on the available evidence, it is more likely than not that such assets will not be realized. The need to establish valuation allowances for deferred tax assets is assessed quarterly. In assessing the requirement for, and amount of, a valuation allowance in accordance with the more likely than not standard for all periods, we give appropriate consideration to all positive and negative evidence related to the realization of the deferred tax assets. This assessment considers, among other matters, the nature, frequency and severity of current and cumulative losses, forecasts of future profitability and foreign source income, the duration of statutory carryforward periods and our experience with operating loss and tax credit carryforward expirations. A history of cumulative losses is a significant piece of negative evidence used in our assessment. If a history of cumulative losses is incurred for a tax jurisdiction, forecasts of future profitability are not used as positive evidence related to the realization of the deferred tax assets in the assessment. We recognize the tax benefits of an uncertain tax position only if those benefits are more likely than not to be sustained based on existing tax law. Additionally, we establish a reserve for tax positions that are more likely than not to be sustained based on existing tax law, but uncertain in the ultimate benefit to be sustained upon examination by the relevant taxing authorities. Unrecognized tax benefits are subsequently recognized at the time the more likely than not recognition threshold is met, the tax matter is effectively settled or the statute of limitations for the relevant taxing authority to examine and challenge the tax position has expired, whichever is earlier. We account for all interest and penalties on uncertain income tax positions as income tax expense. See Note 14, Income Taxes, to the Consolidated Financial Statements for additional information.
Earnings per Share	Earnings Per ShareBasic earnings or loss per share is computed by dividing the earnings or loss attributable to common shares by the sum of the weighted average number of shares of common stock outstanding during the period and the weighted average number of stock-based awards that have vested but not yet been issued during the period. Diluted earnings per share reflects the potential dilution of securities that could share in the earnings. Diluted loss per share would be calculated using basic common shares outstanding, as inclusion of potentially dilutive common shares would be anti-dilutive. See Note 15, Earnings Per Share of Common Stock, to the Consolidated Financial Statements for additional information.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash on hand and short-term investments that have maturities of three months or less when purchased. The Company has no restricted cash.
Receivables	Receivables We sell the vast majority of our products to select, pre-approved customers using customary trade terms that allow for payment in the future. Customer trade receivables and miscellaneous receivables, net of allowances for current expected credit losses, customer credits and warranties are reported in accounts and notes receivable on a net basis. Cash flows from the collection of receivables are classified as operating cash flows on the Consolidated Statements of Cash Flows. We establish credit-worthiness prior to extending credit. We estimate the net of allowances for current expected credit losses of receivables each period. This estimate is based upon the current and forecasted economic conditions as well as an analysis of prior credit losses by receivable type. Account balances are charged off against the allowance when the potential for recovery is considered remote. We do not have any off-balance-sheet credit exposure related to our customers.
Inventories	Inventories Inventories are valued at the lower of cost or net realizable value and cost is determined using the FIFO method of accounting. Additionally, inventory balances are adjusted for estimated obsolete or unmarketable inventory equal to the difference between the cost of inventory and its net realizable value. During the fourth quarter of 2021, the Company changed its method of accounting for U.S. based inventories from the LIFO method to the FIFO method. We believe that this change in accounting method is preferable as it results in a better matching of revenue and expense, it more closely resembles the physical flow of inventory, is a more consistent method to value inventory across our businesses, and results in improved comparability with industry peers. See Note 4, Inventories, to the Consolidated Financial Statements for additional information.
Property Plant and Equipment	Property Plant and Equipment Property, plant and equipment is recorded at cost reduced by accumulated depreciation. Depreciation expense is recognized on a straight-line basis over assets’ estimated useful lives. Machinery and equipment includes manufacturing equipment (depreciated over 3 to 15 years), computer equipment (depreciated over 3 to 5 years) and office furniture and equipment (depreciated over 5 to 7 years). Within manufacturing equipment, assets that are subject to accelerated obsolescence or wear, such as tooling and engraving equipment, are depreciated over shorter periods (3 to 7 years). Heavy production equipment, such as conveyors, are depreciated over longer periods (10 to 15 years). Buildings are depreciated over 15 to 30 years, depending on factors such as type of construction and use. Computer software is amortized over 3 to 7 years. Property, plant and equipment is tested for impairment when indicators of impairment exist, such as operating losses and/or negative cash flows. If an evaluation of the undiscounted future cash flows generated by an asset group indicates impairment, the asset group is written down to its estimated fair value, which is based on its discounted future cash flows. The principal assumption used in these impairment tests is future cash flows, which are derived from those used in our operating plan and strategic planning processes.
Intangible Assets	Intangible Assets Our indefinite-lived intangible assets are primarily trademarks which are integral to our corporate identity and expected to contribute indefinitely to our corporate cash flows. We conduct our annual impairment test for indefinite-lived intangible assets during the fourth quarter and we conduct interim impairment tests if indicators of potential impairment exist. An impairment is recognized if the carrying amount of the asset exceeds its fair value. We first perform a qualitative assessment to determine if it is necessary to perform a quantitative impairment test. If a quantitative impairment test is deemed necessary, the method used to determine the fair value of our indefinite-lived intangible assets is the relief-from-royalty method. The principal assumptions used in our application of this method are revenue growth rate, discount rate and royalty rate. Revenue growth rates are derived from those used in our operating plan and strategic planning processes. The discount rate assumption is calculated based upon an estimated weighted average cost of capital, which we believe reflects the overall level of inherent risk and the rate of return a market participant would expect to achieve. The royalty rate assumption represents the estimated contribution of the intangible asset to overall profits. The method used for valuing our indefinite-lived intangible assets did not change from prior periods. Our long-lived intangible assets are primarily contractual arrangements (amortized over 5 years), wh ich includes non-compete agreements, and
Foreign Currency Transactions	Foreign Currency Transactions For our subsidiaries with non-U.S. dollar functional currency, assets and liabilities are translated at period-end exchange rates. Revenues and expenses are translated at exchange rates effective during each month. Foreign currency translation gains or losses are included as a component of AOCI within equity. Gains or losses on foreign currency transactions are recognized through net income (loss).
Stock-Based Employee Compensation	Stock-Based Employee CompensationWe issue stock-based compensation to certain employees and non-employee directors in different forms, including various types of performance-based share compensation including PSAs, PSUs, PBRSUs and RSUs. We record stock-based compensation expense based on an estimated grant-date fair value. The expense is reflected as a component of SG&A expenses on our Consolidated Statements of Operations. Stock-based compensation expense includes an estimate for forfeitures and anticipated achievement levels and is generally recognized on a straight-line basis over the vesting period for the entire award. See Note 13, Stock-based Compensation, to the Consolidated Financial Statements for additional information.
Lessee, Leases	Leases We lease certain real estate (warehouse and office space), vehicles and equipment. For leases with an initial term of one year or less we recognize lease expense for these leases on a straight-line basis over the lease term. Leases with an initial term of one year or more are recorded on the Consolidated Balance Sheet. We consider all payments fixed unless there is a material impact to the balance sheet at any given time during the lease period. We determine if a contract is a lease at inception. Operating leases are included in operating lease assets, accounts payable and accrued expenses and noncurrent operating lease liabilities in our consolidated balance sheets. Finance leases are included in property and equipment, current installments of long-term debt and long-term debt in our consolidated balance sheets. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we generally use our incremental borrowing rate based on the estimated rate of interest for collateralized borrowing over a similar term of the lease payments at commencement date. We update these rates annually. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain with a compelling economic reason that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. We have elected to combine lease and non-lease components as a single component and account for it as a lease for all asset classes with the exception of land and non-operating buildings. Lease and non-lease components of land and non-operating buildings are generally accounted for separately. We have elected to use a portfolio approach to determine the discount rate and defined portfolio based on the geographic location of the asset by country and duration of the lease.
Recently Adopted Accounting Standards and Recently Issued Accounting Standards	Recently Adopted Accounting Standards On January 1, 2021, we adopted ASU 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes" This new standard eliminates certain exceptions in the ASC, Section 740, related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period, guidance on accounting for franchise taxes and the recognition of deferred tax liabilities for outside basis differences. It also clarifies and simplifies other aspects of the accounting for income taxes. The adoption of the standard did not have a significant impact on our consolidated financial statements.
