Accounting Policies [Abstract]
Accounting Policies	ACCOUNTING POLICIES Principles of Consolidation The consolidated financial statements include the accounts of Glatfelter and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated. Reclassification of Prior Year Presentation Certain prior year amounts in the footnotes to the consolidated financial statements have been reclassified to conform to the current year presentation. Accounting Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingencies as of the balance sheet date and the reported amounts of net sales and expenses during the reporting period. Management believes the estimates and assumptions used in the preparation of these consolidated financial statements are reasonable, based upon currently available facts and known circumstances, but recognizes that actual results may differ from those estimates and assumptions. Discontinued Operations The results of operations for the Specialty Papers business have been classified as discontinued operations for all periods presented in the consolidated statements of income (loss). Cash and Cash Equivalents We classify all highly liquid instruments with an original maturity of three months or less at the time of purchase as cash equivalents. Inventories Our inventories are stated at the lower of cost or net realizable value. Raw materials, in-process and finished goods inventories are valued principally using the average-cost method. Plant, Equipment and Timberlands For financial reporting purposes, depreciation is computed using the straight-line method over the estimated useful lives of the respective assets. The range of estimated service lives used to calculate financial reporting depreciation for principal items of plant and equipment are as follows: Buildings 15 – 45 years Machinery and equipment 5 – 40 years Other 3 – 25 years Maintenance and Repairs Maintenance and repairs costs are charged to income and major renewals and improvements are capitalized. At the time property is retired or sold, the net carrying value is eliminated and any resultant gain or loss is included in income. Valuation of Long-lived Assets, Intangible Assets and Goodwill We evaluate long-lived assets for impairment when a specific event indicates that the carrying value of an asset may not be recoverable. Recoverability is assessed based on estimates of future cash flows expected to result from the use and eventual disposition of the asset. If the sum of expected undiscounted cash flows is less than the carrying value of the asset, the asset’s fair value is estimated, and an impairment loss is recognized for the amount by which the carrying value exceeds the estimated fair value. Goodwill and indefinite-lived intangible assets are not amortized and, therefore, are reviewed for impairment annually, during the fourth quarter, or more frequently if impairment indicators are present. The fair value of our reporting units, which are also our operating segments, is determined using a market approach and a discounted cash flow model. The fair value of non-amortizing tradename intangible assets is determined using a discounted cash flow model and requires the use and analysis of significant assumptions including among others, estimated cash flows consistent with our long-term strategic plan, perpetuity growth rates, capital expenditures, and discount rates. In addition, the discounted cash flow model requires the use of significant judgement to assess the potential impact of macroeconomic conditions including higher energy prices in Europe, raw material inflation in all three segments, logistics costs, competition and similar factors. For goodwill, impairment losses, if any, are recognized for the amount by which the carrying value of the reporting unit exceeds its fair value. The carrying value of a reporting unit is defined using an enterprise premise which is generally determined by the difference between the unit’s assets and operating liabilities. With respect to non-amortizing tradenames, impairment losses, if any, are recognized for the amount by which the carrying value of the tradename exceeds its fair value. For additional information, refer to Note 6 – “ Asset Impairment . “ Income Taxes Income taxes are determined using the asset and liability method of accounting for income taxes in accordance with FASB ASC 740 Income Taxes (“ASC 740”). Under ASC 740, tax expense includes U.S. and international income taxes plus the provision for U.S. taxes on undistributed earnings of international subsidiaries not deemed to be permanently invested. Tax credits and other incentives reduce tax expense in the year the credits are claimed. Certain items of income and expense are not reported in tax returns and financial statements in the same year. The tax effect of such temporary differences is reported in deferred income taxes. Deferred tax assets are recognized if it is more likely than not that the assets will be realized in future years. We establish a valuation allowance for deferred tax assets for which realization is not more likely than not. Significant judgment is required in determining our worldwide provision for income taxes and recording the related assets and liabilities. In the ordinary course of our business, there are many transactions and calculations where the ultimate tax determination is less than certain. We and our subsidiaries are examined by various Federal, State, and foreign tax authorities. We regularly assess the potential outcomes of these examinations and any future examinations for the current or prior years in determining the adequacy of our provision for income taxes. We continually assess the likelihood and amount of potential adjustments and record any necessary adjustments in the period in which the facts that give rise to a revision become known. Investment tax credits are accounted for by the flow-through method, which results in recognition of the benefit in the year in which the credit become available. We account for global intangible low-taxed income (“GILTI”) tax in the period in which it is incurred. The GILTI provisions require entities to include in its U.S. income tax return foreign subsidiary earnings in excess of an allowable return on the foreign subsidiaries’ tangible assets. Treasury Stock Common stock purchased for treasury is recorded at cost. At the date of subsequent reissue, the treasury stock account is reduced by the cost of such stock on the weighted-average cost basis. Foreign Currency Translation Foreign currency translation gains and losses and the effect of exchange rate changes on transactions designated as hedges of net foreign investments are included as a component of other comprehensive income (loss). Transaction gains and losses are included in income in the period in which they occur. Revenue Recognition We recognize revenue, or net sales, in accordance with ASU No. 2014-09, Revenue from Contracts with Customers. Our revenue is earned primarily from the manufacture and sale of engineered materials (“product sales”). Revenue is earned pursuant to contracts, supply agreements and other arrangements with a wide variety of customers. Our performance obligation is to produce a specified product according to technical specifications and, in substantially all instances, to deliver the product. Revenue from product sales is earned at a point in time. We recognize revenue on product sales when we have satisfied our performance obligation and control of the product has passed to the customer thereby entitling us to payment. With respect to substantially all arrangements for product sales, this is deemed to occur when title transfers in accordance with specified shipping terms. Selling prices are fixed at the time the sales arrangement is entered into and payment terms are customary for similar arrangements in our industry. Many of our agreements include customary provisions for volume rebates, discounts and similar incentives. In addition, we are obligated for products that fail to meet agreed upon specification. Provisions for such items are estimated and recorded as sales deductions in the period in which the related revenue is recognized. Refer to Note 8 – “ Revenue ” for additional information about the disaggregation of our net sales. Environmental Liabilities Accruals for losses associated with environmental obligations are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated based on existing legislation and remediation technologies. These accruals are adjusted periodically as assessment and remediation actions continue and/or further legal or technical information develops. Such liabilities are exclusive of any insurance or other claims against third parties. Environmental costs are capitalized if the costs extend the life of the asset, increase its capacity and/or mitigate or prevent contamination from future operations. Recoveries of environmental remediation costs from other parties, including insurance carriers, are recorded as assets when their receipt is assured beyond a reasonable doubt. Earnings Per Share Basic earnings (loss) per share is computed by dividing net income (loss) by the weighted-average common shares outstanding during the respective periods. Diluted earnings per share is computed by dividing net income by the weighted-average common shares and common share equivalents outstanding during the period. In periods in which there is a net loss, diluted loss per share is equal to basic loss per share. The dilutive effect of common share equivalents is considered in the diluted earnings per share computation using the treasury stock method. Financial Derivatives and Hedging Activities We use financial derivatives to manage exposure to changes in foreign currencies and interest rates. In accordance with FASB ASC 815 Derivatives and Hedging (“ASC 815”), we record all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether we have elected to designate a derivative in a hedging relationship and apply hedge accounting, and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. The gain or loss on those derivative instruments designated and qualifying as a hedge of the exposure to variability in expected future cash flows related to forecasted transactions is deferred and reported as a component of accumulated other comprehensive income (loss). Deferred gains or losses are reclassified to our results of operations at the time the hedged forecasted transaction is recorded in our results of operations. The effectiveness of cash flow hedges is assessed at inception and quarterly thereafter. If the instrument matures, is de-designated, becomes ineffective or it becomes probable that the originally forecasted transaction will not occur, the related change in fair value of the derivative instrument is also reclassified from accumulated other comprehensive income (loss) and recognized in earnings. For additional information, refer to Note 22 - " Financial Derivatives and Hedging Activities. " Fair Value of Financial Instruments Under the accounting for fair value measurements and disclosures, a fair value hierarchy was established that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). A financial instrument's level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The three levels of the fair value hierarchy are described below: Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Level 2 - Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates); and inputs that are derived principally from or corroborated by observable market data by correlation or other means. Level 3 - Inputs that are both significant to the fair value measurement and unobservable. Employee Retention Tax Credit The Coronavirus Aid, Relief, and Economic Security Act of 2020 (“CARES”) and the subsequent related amendments provided a refundable payroll tax credit for eligible wages paid to employees in 2020 and 2021. For 2021, the employee retention credit is equal to 70% of qualified wages paid to U.S. employees in quarters where certain criteria are met.

Business Combination and Asset Acquisition [Abstract]
Acquisitions	ACQUISITIONS On May 13, 2021, we completed the acquisition of all the outstanding equity interests in Georgia-Pacific Mt. Holly LLC, Georgia-Pacific's U.S. nonwovens business ("Mount Holly") for $170.9 million. This business includes the Mount Holly, NC manufacturing facility with annual production capacity of approximately 37,000 metric tons and an R&D center and pilot line for nonwovens product development in Memphis, TN. The Mount Holly facility produces high-quality airlaid products for the wipes, hygiene, and other nonwoven materials markets, competing in the marketplace with nonwoven technologies and substrates, as well as other materials focused primarily on consumer based end-use applications. The facility employs approximately 140 people. Mount Holly’s results are reported prospectively from the acquisition date as part of our Airlaid Materials segment. Mount Holly had annual net sales of approximately $100 million in 2020. The Mount Holly acquisition was financed through a combination of cash on hand and borrowings under our revolving credit facility. On October 29, 2021, we completed the acquisition of PMM Holding (Luxembourg) AG, the owner of all of the equity interest in Jacob Holm, a global leading manufacturer of premium quality spunlace nonwoven fabrics for critical cleaning, high-performance materials, personal care, hygiene and medical applications, for approximately $304.0 million for all outstanding shares and the extinguishment of Jacob Holm’s debt. Jacob Holm’s broad product offerings and blue-chip customer base expands our portfolio to include surgical drapes and gowns, wound care, face masks, facial wipes and cosmetic masks. The acquisition of Jacob Holm’s Sontara brand, a leading producer of finished products for critical cleaning wipes and medical apparel, enhances our technological capabilities. Jacob Holm has approximately 760 employees, operates production facilities in the United States, France and Spain, and its revenue in 2020 totaled approximately $400 million. The results of Jacob Holm's operations are reported as Spunlace, a newly formed segment, prospectively from the acquisition date. The Jacob Holm acquisition was financed with the proceeds of a private placement of $500.0 million of senior notes discussed in Note 20 - "Long-term Debt." In 2022, we adjusted the purchase price allocation related to the Jacob Holm acquisition by reducing preacquistion compensation incentive accruals by approximately $0.5 million, and reducing goodwill by the same amount, based on incentive payouts made during the year. The following table sets forth information related to the consideration exchanged for the Jacob Holm acquisition. In thousands Total consideration $ 303,952 Less: Debt repaid (148,000) Cash consideration $ 155,952 The purchase price allocation for the Jacob Holm acquisitions is complete. The allocation of the purchase price to assets acquired and liabilities assumed is as follows: In thousands Jacob Holm Assets Cash and cash equivalents $ 11,426 Accounts receivable 30,271 Inventory 45,340 Prepaid and other current assets 6,727 Plant, equipment and timberlands 158,612 Intangible assets 70,240 Goodwill 48,355 Other assets 26,929 Total assets 397,900 Liabilities Short-term debt 14,081 Accounts payable 25,264 Other current liabilities 21,263 Other long-term liabilities 33,340 Total liabilities 93,948 Total purchase price $ 303,952 For purposes of allocating the total purchase price, assets acquired and liabilities assumed are recorded at their estimated fair market values. The allocations set forth above are based on management’s estimate of the fair value using valuation techniques such as discounted cash flow models, appraisals and similar methodologies. Acquired property, plant and equipment in both acquisitions are being depreciated on a straight-line basis with estimated remaining lives ranging from 5 years to 35 years. Intangible assets recorded in connection with the Mount Holly acquisition consist of customer relationships and are being amortized on a straight-line basis (11 years). With respect to the Jacob Holm acquisition, identifiable intangible assets consist of trade and product names (15 to 20-year life), technical know-how (8 to 20-year life) and customer relationships (20-year life). These assets are being amortized on a straight-line basis. The goodwill arising from the acquisitions largely relates to strategic benefits, product and market diversification, assembled workforce, and similar factors. Goodwill recorded in connection with the Mount Holly transaction is deductible for federal tax purposes over 15 years. Additional information is discussed in Note 16 - "Goodwill and Intangible Assets." In connection with the Jacob Holm acquisition and as provided for in the underlying Share Purchase Agreement, we recorded a $17.2 million indemnification asset related to certain potential tax liabilities. The indemnification asset is presented above under the caption "Other assets." During 2022, we wrote off the entire amount of goodwill recorded as part of the Jacob Holm acquisition. Additional information is discussed in Note 6 - “ Goodwill and Ass et Impairments . ” For purposes of presenting the pro forma financial information, the legal and professional costs directly related to the acquisitions have been eliminated.

Asset Impairment Charges [Abstract]
Goodwill and Asset Impairments	GOODWILL AND ASSET IMPAIRMENTS During the fourth quarter of 2022, we recognized a goodwill and asset impairment charge for our Composite Fibers segment of $30.7 million. This charge includes a $20.3 million goodwill impairment for the Composite Fibers segment, primarily driven by higher valuation discount rates despite our expectation of improvements in future financial results compared to our forecast included in our valuation performed in Q1 2022. In addition, we recognized an $10.4 million non-cash asset impairment charge related to our OberSchmitten, Germany facility based on our expectations of future cash flows for this site. We are currently evaluating strategic alternatives for this facility. During the third quarter of 2022, we recognized a non-cash goodwill impairment charge for our Spunlace segment of $42.5 million. The Spunlace segment has faced continued inflationary challenges which had escalated since our acquisition of this business in late 2021. Our selling price increases have been insufficient to offset the impact of inflation. Furthermore, the Spunlace segment has been impacted by unexpected supply chain and other operational issues which, in combination with the commercial issues, have resulted in an unexpected increase in operating losses. Although, management expects it will address the commercial, as well as, operational challenges that have impacted the profitability of this segment, the timing to effectuate the necessary changes to improve performance of this segment will be longer than previously expected. In the first quarter of 2022, in connection with an assessment of potential impairment of long-lived and indefinite-lived intangible assets stemming from the compounding impacts resulting from the Russia/Ukraine military conflict and related sanctions, we recorded a $117.3 million non-cash asset impairment charge related to Composite Fibers' Dresden facility and an impairment of Composite Fibers' goodwill. Dresden is a single-line facility that produces wallcover base paper, the majority of which is sold into the Russian and Ukrainian markets. As a direct result of the economic impacts from the conflict, and the disruptions in the underlying financial systems and prohibition of the export of sanctioned wallcover base paper to Russia, management expects a significant reduction in wallcover revenues and associated cash flows for the foreseeable future. In addition, the conflict is expected to significantly impact energy prices and also impact other Composite Fibers products that are also subject to export sanctions into Russia. Accordingly, a charge was recorded to reduce the carrying value of the Dresden fixed assets and intangible assets (technological know-how, customer relationships, and an indefinite-lived trade name), along with Composite Fibers’ goodwill to fair value. During the second quarter of 2020, in connection with an assessment of potential impairment of indefinite-lived intangible assets, we recorded a $0.9 million non-cash asset impairment charge related to a trade name intangible asset acquired in connection with our Composite Fibers segment’s 2013 Dresden acquisition. The charge was due to a change in the estimated fair value of the trade name, primarily driven by lower forecasted wallcover net sales associated with economic instability in Russia and Ukraine together with the impact of the COVID-19 pandemic on this business. The fair value of the asset was estimated using a discounted cash flow model (Level 3 fair value classification) . The following table summarizes the impairment charges recorded in the accompanying consolidated statements of income (loss) under the caption “Goodwill and other asset impairment charges:” In thousands 2022 2021 2020 Plant, property and equipment $ 37,936 $ — $ — Technological know-how 18,443 — — Customer relationships 11,695 — — Tradename 3,530 — 900 Goodwill 118,952 — — Total $ 190,556 $ — $ 900 The fair value of the underlying assets was estimated using discounted cash flow models, independent appraisals and similar methods, all of which are Level 3 fair value classification. As a result of economic sanctions and disruptions to the financial markets, certain Russian and Ukrainian customers are not able to satisfy outstanding accounts receivables. As such, during 2022, we recognized bad debt expense of approximately $2.9 million directly related to Russian and Ukrainian customers. Furthermore, during 2022, we increased inventory reserves by approximately $0.3 million, primarily related to wallcover products.

The effective income tax rate for the year ended December 31, 2021 was unfavorably impacted by operating losses in the U.S., restructuring and other non-recurring costs for which no tax benefit was recorded.

These NOL carryforwards are available to offset future taxable income. $0.8 million of the federal NOL carryforward expires in 2037.The remaining $79.0 million of the federal NOL has an indefinite carryforward and never expires. The state NOL carryforwards expire at various times and in various amounts beginning in 2023. Certain foreign NOL carryforwards begin to expire after 2025. The federal and state NOL carryforwards on the income tax returns filed included unrecognized tax benefits taken in prior years. The deferred tax assets recognized for financial statement purposes for such NOL carryforwards are presented net of these unrecognized tax benefits. In addition, we had various federal tax credit carryforwards totaling $14.9 million which begin to expire in 2035 and state tax credit carryforwards totaling $3.0 million, which begin to expire in 2028. As of December 31, 2022 and 2021, we had a valuation allowance of $53.0 million and $24.5 million, respectively, against net deferred tax assets, primarily due to uncertainty regarding the ability to utilize federal, state and foreign tax NOL carryforwards, federal and foreign interest limitation carryforwards and certain state tax credits. In assessing the need for a valuation allowance, management considers all available positive and negative evidence in its analysis. Based on this analysis, we recorded a valuation allowance for the portion of deferred tax assets where the weight of available evidence indicated it is more likely than not that the deferred tax assets will not be realized. Tax credits and other incentives reduce tax expense in the year the credits are claimed. We recorded tax credits of $0.7 million, $0.0 million and $3.3 million in 2022, 2021 and 2020, respectively, related to research and development credits. At December 31, 2022 and 2021, unremitted earnings of certain subsidiaries outside the United States deemed to be indefinitely reinvested totaled $130.0 million and $107.0 million, respectively. Because the unremitted earnings of those subsidiaries are deemed to be indefinitely reinvested as of December 31, 2022 and because we have no need for or plans to repatriate such earnings, no deferred tax liability has been recognized in our consolidated financial statements with regard to those subsidiaries. In 2021, we designated unremitted earnings of a subsidiary as not indefinitely reinvested. As of December 31, 2022, we have $2.6 million of deferred tax liabilities recorded with regard to the unremitted earnings of that subsidiary. As of December 31, 2022, 2021 and 2020, we had $56.5 million, $55.7 million and $46.3 million of gross unrecognized tax benefits, respectively. As of December 31, 2022, if such benefits were to be recognized, approximately $53.0 million would be recorded as a component of income tax expense, thereby affecting our effective tax rate.

The amount of income taxes we pay is subject to ongoing audits by federal, state and foreign tax authorities, which often result in proposed assessments. Management performs a comprehensive review of its global tax positions on a quarterly basis and accrues amounts for uncertain tax positions. Based on these reviews and the result of discussions and resolutions of matters with tax authorities and the closure of tax years subject to tax audit, reserves are adjusted as necessary. However, future results may include favorable or unfavorable adjustments to our estimated tax liabilities in the period the assessments are determined or resolved or as such statutes are closed. Due to potential for resolution of federal, state and foreign examinations, and the expiration of various statutes of limitation, it is reasonably possible our gross unrecognized tax benefits may decrease within the next twelve months by a range of zero to $8.4 million. The majority of this range relates to tax positions taken in foreign jurisdictions. We recognize interest and penalties related to uncertain tax positions as income tax expense.

Stock-Based Compensation

Stock-Based Compensation	12 Months Ended

Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation	STOCK-BASED COMPENSATION On May 5, 2022, upon Board and shareholder approval, the Glatfelter Corporation 2022 Long-Term Incentive Plan became effective and is a successor plan to the P. H. Glatfelter Amended and Restated Long-Term Incentive Plan (collectively, the “LTIP”). The LTIP continues to provide for the issuance of Glatfelter common stock to eligible participants in the form of restricted stock units, restricted stock awards, non-qualified stock options, performance shares, incentive stock options and performance units. Furthermore, the LTIP increases the number shares previously available for issuance by 1,400,000 shares. As of December 31, 2022, there were 2,467,908 shares of common stock available for future issuance under the LTIP. Pursuant to terms of the LTIP, we have issued to eligible participants restricted stock units (“RSUs”), performance share awards (“PSAs”) and stock-only stock appreciation rights (“SOSARs”). Restricted Stock Units (“RSUs”) and Performance Share Awards (“PSAs”) Awards of RSUs and PSAs are made under our LTIP. The vesting of RSUs is generally based on the passage of time, generally over a three-year period or in certain instances the RSUs were issued with five-year cliff vesting. PSAs are issued to members of management and vesting is based on achievement of cumulative financial performance targets covering a two-year period followed by an additional one-year service period. The performance measures include a minimum, target and maximum performance level providing the grantees an opportunity to receive more or less shares than targeted depending on actual financial Performance. In addition, PSA awards include a modifier based on the three-year total shareholder return relative to a broad market index. For RSUs, the grant date fair value of the awards, or the closing price per common share on the date of the award, is used to determine the amount of expense to be recognized over the applicable service period. For PSAs, the grant date fair value is estimated using a lattice model. The significant inputs include the stock price, volatility, dividend yield, and risk-free rate of return. Settlement of RSUs and PSAs will be made in shares of our common stock currently held in treasury. In 2022, we issued awards to employees of RSUs and PSAs under our LTIP. In 2022, 50% of fair value of the awards granted were RSUs, which vest based on the passage of time, generally over a graded three-year period or, in certain instances, the RSUs were cliff vesting after one In addition, in 2022, we issued 360,000 PSAs and 240,000 RSUs to our new CEO, Thomas Fahnemann, as part of his on-boarding compensation package. These PSAs have a 3-year service and performance requirement that is based on our stock price achieving certain levels during the performance period. Specifically, if the Company’s closing stock price is $10 or higher for 20 consecutive days during the performance period, 50% of the award is achieved. If the stock price exceeds $18 per share for 20 consecutive days during the performance period 100% of the award is achieved. The RSUs vest over a three-year period with 50% vesting after two years and the remainder vesting after three years. In 2022, in connection with his separation from the Company, certain unvested RSUs and PSAs of the former CEO were forfeited, and as a result, the Company recognized a stock-based compensation benefit of approximately $3.1 million which is included in Selling, general and administrative expense on the accompanying consolidated statements of income (loss). For RSUs, the grant date fair value of the awards, or the closing price per common share on the date of the award, is used to determine the amount of expense to be recognized over the applicable service period. For PSAs, the grant date fair value is estimated using a lattice model. The significant inputs include the stock price, volatility, dividend yield, and risk-free rate of return. Settlement of RSUs and PSAs will be made in shares of our common stock currently held in treasury.

Retirement Benefits [Abstract]
Retirement Plans and Other Post-Retirement Benefits	RETIREMENT PLANS AND OTHER POST-RETIREMENT BENEFITS Prior to May 2019, we provided non-contributory retirement benefits under both funded and unfunded plans to all U.S. employees and to certain non-U.S. employees in Germany. As discussed in more detail below, we terminated our U.S. qualified pension plan effective June 30, 2019 and replaced the benefits with an enhanced 401(k) defined contribution plan. Participation and benefits under the plans were based upon the employees’ date of hire. U.S. benefits accrued under the terminated pension plan was based on a final average pay formula or cash balance formula for salaried employees. In December 2019, our Board of Directors approved the freezing of benefit accruals in the non-qualified pension plan for active participants effective December 31, 2019. As of January 1, 2020, each active participant’s frozen non-qualified pension benefit was transferred to a newly approved Deferred Compensation Plan non-qualified benefit plan and will earn interest credits going forward. The Deferred Compensation Plan also provides for employer contributions and, beginning in 2022, the Plan may provide for elective employee deferrals. Under the Deferred Compensation Plan, participants are eligible to receive annual Company contributions that such participants would have received under our 401(k) Savings Plan, but for certain limitations imposed by the Internal Revenue Code on 401(k) plan contributions (“Company Contributions”). Unless otherwise determined by the Compensation Committee, Company Contributions under the Deferred Compensation Plan will not exceed 7% of a participant’s annual eligible compensation that is in excess of the Internal Revenue Code compensation limit for 401(k) plans. As of December 31, 2022 and 2021, the remaining non-contributory pension plans are unfunded non-qualified plans. Non-U.S. benefits were based on average salary and years of service. We use a December 31-measurement date for all of our defined benefit plans. We also provide certain health care benefits to eligible U.S.-based retired employees. Participation in the plan is closed to any salaried employees hired after December 31, 2006. For retirees prior to age 65, these benefits consists of either a Company provided fixed contribution, as determined on an annual basis, to the participant’s health reimbursement account or providing group medical insurance coverage with a subsidy cap of $10,000 per year, as determined by date of retirement. For certain retirees over age 65, these benefits consists of a fixed payment to defray the costs of Medicare. All information presented in the following tables represents amounts attributable to continuing operations.

Leases [Abstract]
Leases	LEASES We enter into a variety of arrangements in which we are the lessee for the use of automobiles, forklifts and other production equipment, production facilities, warehouses and office space. We determine if an arrangement contains a lease at inception. All our lease arrangements are operating leases and are recorded in the consolidated balance sheet under the caption “Other assets” and the lease obligation is under “Other current liabilities” and “Other long-term liabilities.” We currently do not have any finance leases. Operating lease right of use (“ROU”) assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. ROU assets also include any initial direct costs incurred and any lease payments made at or before the lease commencement date, less lease incentives received. We use our incremental borrowing rate based on information available at the commencement date in determining the lease liabilities as our leases generally do not provide an implicit rate. Lease terms may include options to extend or terminate when we are reasonably certain that the option will be exercised. Lease expense is recognized on a straight-line basis over the lease term. We also have arrangements with both lease and non-lease components. We elected the practical expedients not to separate non-lease components from lease components for our real estate and automobile leases and the lack of need to reassess classification. We elected to apply the short-term lease measurement and recognition exemption in which ROU assets and lease liabilities are not recognized for arrangements less than twelve months in duration.

Revolving Loans borrowings are available in U.S. Dollars, Euros, British Pound Sterling, and Canadian Dollars and the borrowing of Term Loans are available in Euros. The principal amount of the Term Loan amortizes in consecutive quarterly installments of principal, with each such quarterly installment to be in an amount equal to 1.25% of the Term Loan funded. On May 9, 2022, we entered into an amendment to the Credit Agreement. The amendment: i) increases the permitted maximum ratio of consolidated total net debt to consolidated adjusted EBITDA (“leverage ratio”); ii) increases the maximum interest rate borrowing margin to be applied to the applicable index by 25 basis points; and iii) pledges as collateral substantially all domestic assets to secure obligations owed under the Credit Agreement. As amended, we are obligated to maintain a maximum ratio of consolidated total net debt to consolidated adjusted EBITDA of 6.75 to 1.0 until the quarter ended December 31, 2023, after which the maximum leverage ratio steps down to 4.0 to 1.0. Borrowing rates for the Revolving Loans are determined at our option at the time of each borrowing. For all U.S. Dollar denominated Revolving Loan borrowings, the borrowing rate is either, (a) the bank’s base rate which is equal to the greater of i) the prime rate; ii) the overnight bank funding rate plus 50 basis points; or iii) the daily Euro-rate plus 100 basis points plus an applicable spread over either i), ii) or iii) ranging from 12.5 basis points to 100 basis points based on the Company’s leverage ratio and its corporate credit ratings determined by Standard & Poor’s Rating Services and Moody’s Investor Service, Inc. (the “Corporate Credit Rating”); or (b) the daily Euro-rate or EURIBOR-rate plus an applicable margin ranging from 112.5 basis points to 225 basis points based on the Company’s leverage ratio and the Corporate Credit Rating. For the Term Loan and non-U.S. Dollar denominated borrowings, interest is based on (b) above. The Credit Agreement contains a number of customary covenants for financings of this type that, among other things, restrict our ability to dispose of or create liens on assets, incur additional indebtedness, limits certain intercompany financing arrangements, make acquisitions and engage in mergers or consolidations. The Credit Agreement also contains covenants requiring a minimum interest coverage ratio and provisions limiting our ability to, among other things, (i) incur debt and guaranty obligations, (ii) incur liens, (iii) make loans, advances, investments and acquisitions, (iv) merge or liquidate, or (v) sell or transfer assets. All remaining principal outstanding and accrued interest under the Revolving Credit Facility and the Term Loan will be due and payable on September 2, 2026 and February 8, 2024, respectively. As of December 31, 2022, the leverage ratio, as calculated in accordance with the definition in our Credit Agreement, was 6.0x. A breach of these requirements would give rise to certain remedies under the Revolving Credit Facility, among which is the termination of the agreement. On October 25, 2021, we issued $500 million aggregate principal amount of 4.750% senior notes due 2029 (the “Notes”). The Notes are guaranteed on a senior unsecured basis, jointly and severally, by each of our existing and future domestic restricted subsidiaries that guarantees our obligations under the Credit Agreement, and/or certain other indebtedness (the “Guarantees”). The Notes were issued pursuant to an indenture dated as of October 25, 2021 (the “Base Indenture”), as supplemented by the supplemental indenture dated as of October 25, 2021 (the “Supplemental Indenture” and, together with the Base Indenture, the “Indenture”) among the Company, certain subsidiaries of the Company party thereto (the “Guarantors”) and Wilmington Trust, National Association, as trustee. The net proceeds from the offering of the Notes, together with cash on hand, were used to pay the purchase price of the Jacob Holm acquisition, to repay certain indebtedness of Jacob Holm, to repay outstanding revolving borrowings under the Revolving Credit Facility, and to pay estimated fees and expenses. The Notes will mature on November 15, 2029. Interest on the Notes accrues at the rate of 4.750% per annum and is payable semi-annually in arrears on May 15 and November 15 of each year, commencing on May 15, 2022. The Notes are redeemable, in whole or in part, at any time at the redemption prices specified in the underlying indenture. Prior to November 15, 2024, we may redeem some or all of the Notes at a "make-whole" premium as specified. The Notes contain various covenants customary to indebtedness of this nature, including limitations on i) the amount of indebtedness that may be incurred; ii) certain restricted payments including common stock dividends; iii) distributions from certain subsidiaries; iv) sales of assets; v) transactions amongst subsidiaries; and vi) incurrence of liens on assets. In addition, the Notes contain cross default provisions that could result in all such notes becoming due and payable in the event of a failure to repay debt outstanding under the Credit Agreement at maturity or a default under the Credit Agreement that accelerates the debt outstanding thereunder. As of December 31, 2022, we met all of the requirements of our debt covenants. Glatfelter Gernsbach GmbH (“Gernsbach”), a wholly-owned subsidiary of ours, entered into a series of borrowing agreements with IKB Deutsche Industriebank AG, Düsseldorf (“IKB”). Each of the borrowings require quarterly repayments of principal and interest and provide for representations, warranties and covenants customary for financings of these types. The financial covenants contained in each of the IKB loans, which relate to the minimum ratio of consolidated EBITDA to consolidated interest expense and the maximum ratio of consolidated total net debt to consolidated adjusted EBITDA, will be calculated by reference to our Credit Agreement. In 2021, Gernsbach also entered into two fixed-rate non-amortizing term loans with certain financial institutions. Similar to the IKB loans discussed above, the financial covenants of these borrowings are calculated by reference to the Credit Agreement. Aggregated unamortized deferred debt issuance costs incurred in connection with all of our outstanding debt totaled $10.5 million at December 31, 2022. The deferred costs are being amortized on a straight-line basis over the life of the underlying instruments. Amortization expense related to deferred debt issuance costs totaled $1.9 million, $0.9 million and $0.6 million in 2022, 2021 and 2020, respectively. The following schedule sets forth the amortization of our term loan agreements together with the maturity of our other long-term debt during the indicated year. In thousands 2023 $ 40,435 2024 184,132 2025 980 2026 — 2027 118,685 Thereafter 500,000 Glatfelter Corporation guarantees all debt obligations of its subsidiaries. All such obligations are recorded in these consolidated financial statements. As of December 31, 2022 and 2021, we had $4.7 million and $6.7 million, respectively, of letters of credit issued to us by certain financial institutions. The letters of credit, which reduce amounts available under our revolving credit facility, provide financial assurances for the performance of long-term monitoring activities associated with the Fox River environmental matter and for the benefit of certain state workers compensation insurance agencies in conjunction with our self-insurance program. We bear the credit risk on this amount to the extent that we do not comply with the provisions of certain agreements. No amounts are outstanding under the letters of credit.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Derivatives and Hedging Activities	FINANCIAL DERIVATIVES AND HEDGING ACTIVITIES As part of our overall risk management practices, we enter into financial derivatives primarily designed to either i) hedge foreign currency risks associated with forecasted transactions – “cash flow hedges”; ii) mitigate the impact that changes in currency exchange rates have on intercompany financing transactions and foreign currency denominated receivables and payables – “foreign currency hedges”; or iii) convert variable interest rate debt to fixed rates. Derivatives Designated as Hedging Instruments - Cash Flow Hedges We designate certain currency forward contracts as cash flow hedges of forecasted raw material purchases, certain production costs or capital expenditures with exposure to changes in foreign currency exchange rates. Changes in the fair value of derivatives that are designated and qualify as cash flow hedges of foreign exchange risk are deferred as a component of accumulated other comprehensive income in the accompanying consolidated balance sheets. With respect to hedges of forecasted raw material purchases or production costs, the amount deferred is subsequently reclassified into costs of products sold in the period that inventory produced using the hedged transaction affects earnings. For hedged capital expenditures, deferred gains or losses are reclassified and included in the historical cost of the capital asset and subsequently affect earnings as depreciation is recognized. We had the following outstanding derivatives that were used to hedge foreign exchange risks associated with forecasted transactions and designated as hedging instruments: December 31, In thousands 2022 2021 Derivative Sell/Buy - sell notional Euro / British Pound 18,961 18,823 U.S. Dollar / British Pound 34,501 16,205 U.S. Dollar / Euro 824 658 Sell/Buy - buy notional Euro / Philippine Peso 1,030,114 896,291 British Pound / Philippine Peso 1,144,839 1,121,183 Euro / U.S. Dollar 78,435 108,467 U.S. Dollar / Canadian Dollar 36,423 36,904 These contracts have maturities of eighteen months or less. On June 15, 2022, we terminated a €180 million notional value floating-to-fixed interest rate swap agreement with certain financial institutions that was entered into in October 2019 and was to mature in December 2022. During the life of the swap, we paid a fixed interest rate of the applicable margin plus 0.0395% on €180 million of the underlying variable rate term loan. We received the greater of 0.00% or EURIBOR. At termination, we recognized a deferred gain of $0.4 million that will be amortized into interest expense through December 2022. Derivatives Designated as Hedging Instruments – Net Investment Hedge The €220 million Term Loan discussed in Note 20 – “ Long-Term Debt” is designated as a net investment hedge of our Euro functional currency foreign subsidiaries. During 2022, we recognized a pre-tax gain of $10.8 million and in 2021 a pre-tax gain of $18.6 million on the remeasurement of the term loan from changes in currency exchange rates. Such amounts are recorded as a component of Other Comprehensive Income (Loss). On September 6, 2022, we terminated a $150.0 million cross currency swap agreement with certain financial institutions that was entered into in March 2022 and was to mature in May 2025. Pursuant to the terms of the swap, we agreed to receive 4.750% interest denominated in U.S. dollars and we agreed to pay 3.06% interest denominated in euros. We designated the cross-currency swap as a hedge of our net investment in certain euro functional currency subsidiaries. We collected cash proceeds of approximately $15.2 million upon termination. The gain associated with the swap remains in accumulated other comprehensive loss. Derivatives Not Designated as Hedging Instruments - Foreign Currency Hedges We also enter into forward foreign exchange contracts to mitigate the impact changes in currency exchange rates have on balance sheet monetary assets and liabilities. None of these contracts are designated as hedges for financial accounting purposes and, accordingly, changes in value of the foreign exchange forward contracts and in the offsetting underlying on-balance-sheet transactions are reflected in the accompanying consolidated statements of income (loss) under the caption “Other, net.” December 31, In thousands 2022 2021 Derivative Sell/Buy - sell notional U.S. Dollar / British Pound 28,600 26,600 British Pound / Euro 2,800 3,400 U.S. Dollar / Swiss Franc — 2,180 British Pound / Swiss Franc 2,535 1,025 Euro / Swiss Franc — 2,750 Euro / U.S. Dollar 9,630 11,000 Sell/Buy - buy notional Euro / U.S. Dollar 2,900 20,900 British Pound / Euro 15,950 5,300 Swiss Franc / Euro 2,250 — Swiss Franc / U.S. Dollar 930 — Chinese Yuan / U.S. Dollar 4,400 — These contracts have maturities of one month from the date originally entered into.

The following table summarizes the amount of income or loss from derivative instruments recognized in our results of operations for the periods indicated and the line items in the accompanying consolidated statements of income (loss) where the results are recorded: Year ended December 31, In thousands 2022 2021 2020 Designated as hedging: Forward foreign currency exchange contracts: Cost of products sold $ (7,896) $ (382) $ (5,503) Interest expense (335) 85 83 Not designated as hedging: Forward foreign currency exchange contracts: Other – net 1,240 2,666 1,679 The impact of activity not designated as hedging was substantially all offset by the remeasurement of the underlying on-balance sheet item. The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy are described in Note 2 – “ Accounting Policies .” The fair values of the foreign exchange forward contracts are considered to be Level 2. These contracts are valued using foreign currency forward and interest rate curves. The fair value of each contract is determined by comparing the contract rate to the forward rate and discounting to present value. Contracts in a gain position are recorded in the accompanying consolidated balance sheets under the caption “Prepaid expenses and other current assets” and the value of contracts in a loss position is recorded under the caption “Other current liabilities.” A rollforward of fair value amounts recorded as a component of accumulated other comprehensive income is as follows: In thousands 2022 2021 Balance at January 1, $ 2,889 $ (3,460) Deferred gains on cash flow hedges 5,584 6,646 Reclassified to earnings (8,231) (297) Balance at December 31, $ 242 $ 2,889 We expect substantially all of the amounts recorded as a component of accumulated other comprehensive income will be realized in results of operations within the next twelve Credit risk related to derivative activity arises in the event a counterparty fails to meet its obligations to us. This exposure is generally limited to the amounts, if any, by which the counterparty’s obligations exceed our obligation to them. Our policy is to enter into contracts only with financial institutions which meet certain minimum credit ratings.

At December 31, 2022, required minimum annual payments due under operating leases and other similar contractual obligations aggregated $35.3 million and $35.8 million, respectively. Fox River - Neenah, Wisconsin Background We have previously reported that we face liabilities associated with environmental claims arising out of the presence of polychlorinated biphenyls (“PCBs”) in sediments in the lower Fox River, on which our former Neenah facility was located, and in the Bay of Green Bay, Wisconsin (collectively, the “Site”). Since the early 1990s, the United States, the State of Wisconsin and two Indian tribes (collectively, the “Governments”) have pursued a cleanup of a 39-mile stretch of river from Little Lake Butte des Morts into Green Bay and natural resource damages (“NRDs”). The United States originally notified several entities that they were potentially responsible parties (“PRPs”); however, after giving effect to settlements reached with the Governments, the remaining PRPs exposed to continuing obligations to implement the remainder of the cleanup consist of us, Georgia-Pacific Consumer Products, L.P. (“Georgia-Pacific”) and NCR Corporation. The United States Environmental Protection Agency (“EPA”) has divided the Site into five “operable units,” including the most upstream portion of the Site on which our facility was located (“OU1”) and four downstream reaches of the river and bay (“OU2-5”). Over the past several years, we and certain other PRPs completed all remedial actions pursuant to applicable consent decrees or a Unilateral Administrative Order. In January 2019, we reached an agreement with the United States, the State of Wisconsin, and Georgia-Pacific to resolve all remaining claims among those parties. Under the Glatfelter consent decree, we are primarily responsible for long-term monitoring and maintenance in OU2-OU4a and for reimbursement of government oversight costs paid after October 2018. Finally, we remain responsible for our obligation to continue long-term monitoring and maintenance under our OU1 consent decree. Cost estimates Our remaining obligations under the OU1 consent decree consist of long-term monitoring and maintenance. Furthermore, we are primarily responsible for long-term monitoring and maintenance in OU2-OU4a over a period of at least 30 years. The monitoring activities consist of, among others, testing fish tissue, sampling water quality and sediment, and inspections of the engineered caps. In 2018, we entered into a fixed-price, 30-year agreement with a third party for the performance of all of our monitoring and maintenance obligations in OU1 through OU4a with limited exceptions, such as, for extraordinary amounts of cap maintenance or replacement. Our obligation under this agreement is included in our total reserve for the Site. We are obligated to make the regular payments under that fixed-price contract until the remaining amount due is less than the OU1 escrow account balance. We are permitted to pay for this contract using the remaining balance of the escrow account established by us and WTM I Company (“WTM I”) another PRP, under the OU1 consent decree during any period that the balance in the escrow account exceeds the amount due under our fixed-price contract. As of December 31, 2022, the escrow account balance, which is included in the consolidated balance sheet under the caption “Other assets” totaled $8.8 million which is less than amounts due under the fixed-price contract by approximately $1.2 million. Our obligation to pay this difference is secured by a letter of credit. Under the consent decree, we are responsible for reimbursement of government oversight costs paid from October 2018 and later over approximately the next 30 years. Reserves for the Site Our reserve for past and future government oversight costs and long-term monitoring and maintenance is set forth below: Year ended December 31, In thousands 2022 2021 Balance at January 1, $ 16,200 $ 18,455 Payments (1,848) (2,458) Accretion 195 203 Balance at December 31, $ 14,547 $ 16,200 The payments set forth above represent payments for government oversight costs for amounts due under the long-term monitoring and maintenance agreement. Of our total reserve for the Fox River, $2.2 million is recorded in the accompanying December 31, 2022, consolidated balance sheet under the caption “Environmental liabilities” and the remaining $12.3 million is recorded under the caption “Other long-term liabilities.” Range of Reasonably Possible Outcomes . Based on our analysis of all available information, including but not limited to decisions of the courts, official documents such as records of decision, discussions with legal counsel, cost estimates for future monitoring and maintenance and other post-remediation costs to be performed at the Site, we do not believe that our costs associated with the Fox River matter could exceed the aggregate amounts accrued by a material amount.

There is no comprehensive, authoritative body of guidance for management accounting equivalent to accounting principles generally accepted in the United States of America; therefore, the financial results of individual segments are not necessarily comparable with similar information for any other company. The management accounting process uses assumptions and allocations to measure performance of the operating segments. Methodologies are refined from time to time as management accounting practices are enhanced and businesses change. The costs incurred by support areas not directly aligned with the operating segments are allocated primarily based on an estimated utilization of support area services. Management evaluates results of operations of the operating segments before pension expense, certain corporate level costs, and the effects of certain gains or losses not considered to be related to the core business operations. Management believes that this is a more meaningful representation of the operating performance of its core businesses, the profitability of segments and the extent of cash flow generated from these core operations. Such amounts are presented under the caption “Other and Unallocated.” In the evaluation of operating segment results, management does not use any measures of total assets. This presentation is aligned with the management and operating structure of our company. It is also on this basis that the Company’s performance is evaluated internally and by the Company’s Board of Directors. Our Airlaid Materials segment is a leading global supplier of highly absorbent cellulose-based airlaid nonwoven materials used in the following categories: • Feminine hygiene and other hygiene applications; • Specialty wipes; • Tabletop; • Adult incontinence; • Home care; • Food pads; and • Other consumer and industrial products. The Composite Fibers segment serves customers globally and focuses on higher value-added products in the following categories: • Food & beverage; • Technical specialties; • Wallcovering; • Composite laminates; and • Metallized products. The Spunlace segment is a global leading specialist manufacturer of premium quality spunlace nonwovens for critical cleaning, high-performance materials, personal care, hygiene and medical applications. The categories served by Spunlace include: • Consumer wipes; • Critical cleaning; • Health care; • Hygiene; • High performance; and • Beauty care. Disaggregated net sales by categories and geographic region for the segments is presented in Item 8 Financial Statements and Supplementary Data, Note 8 – “ Revenue .” In 2022, 2021 and 2020, approximately 15%, 16% and 16%, respectively, of our consolidated net sales were from sales to Procter & Gamble Company, a customer in the Airlaid Materials and Spunlace segments.

Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of Glatfelter and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated. Reclassification of Prior Year Presentation Certain prior year amounts in the footnotes to the consolidated financial statements have been reclassified to conform to the current year presentation.
Accounting Estimates	Accounting Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingencies as of the balance sheet date and the reported amounts of net sales and expenses during the reporting period. Management believes the estimates and assumptions used in the preparation of these consolidated financial statements are reasonable, based upon currently available facts and known circumstances, but recognizes that actual results may differ from those estimates and assumptions.
Discontinued Operations	Discontinued Operations The results of operations for the Specialty Papers business have been classified as discontinued operations for all periods presented in the consolidated statements of income (loss).
Cash and Cash Equivalents	Cash and Cash Equivalents We classify all highly liquid instruments with an original maturity of three months or less at the time of purchase as cash equivalents.
Inventories	Inventories Our inventories are stated at the lower of cost or net realizable value. Raw materials, in-process and finished goods inventories are valued principally using the average-cost method.
Plant, Equipment and Timberlands	Plant, Equipment and Timberlands For financial reporting purposes, depreciation is computed using the straight-line method over the estimated useful lives of the respective assets. The range of estimated service lives used to calculate financial reporting depreciation for principal items of plant and equipment are as follows: Buildings 15 – 45 years Machinery and equipment 5 – 40 years Other 3 – 25 years
Maintenance and Repairs	Maintenance and Repairs Maintenance and repairs costs are charged to income and major renewals and improvements are capitalized. At the time property is retired or sold, the net carrying value is eliminated and any resultant gain or loss is included in income.
Valuation of Long-lived Assets, Intangible Assets and Goodwill	Valuation of Long-lived Assets, Intangible Assets and Goodwill We evaluate long-lived assets for impairment when a specific event indicates that the carrying value of an asset may not be recoverable. Recoverability is assessed based on estimates of future cash flows expected to result from the use and eventual disposition of the asset. If the sum of expected undiscounted cash flows is less than the carrying value of the asset, the asset’s fair value is estimated, and an impairment loss is recognized for the amount by which the carrying value exceeds the estimated fair value. Goodwill and indefinite-lived intangible assets are not amortized and, therefore, are reviewed for impairment annually, during the fourth quarter, or more frequently if impairment indicators are present. The fair value of our reporting units, which are also our operating segments, is determined using a market approach and a discounted cash flow model. The fair value of non-amortizing tradename intangible assets is determined using a discounted cash flow model and requires the use and analysis of significant assumptions including among others, estimated cash flows consistent with our long-term strategic plan, perpetuity growth rates, capital expenditures, and discount rates. In addition, the discounted cash flow model requires the use of significant judgement to assess the potential impact of macroeconomic conditions including higher energy prices in Europe, raw material inflation in all three segments, logistics costs, competition and similar factors. For goodwill, impairment losses, if any, are recognized for the amount by which the carrying value of the reporting unit exceeds its fair value. The carrying value of a reporting unit is defined using an enterprise premise which is generally determined by the difference between the unit’s assets and operating liabilities. With respect to non-amortizing tradenames, impairment losses, if any, are recognized for the amount by which the carrying value of the tradename exceeds its fair value. For additional information, refer to Note 6 – “ Asset Impairment . “
Income Taxes	Income Taxes Income taxes are determined using the asset and liability method of accounting for income taxes in accordance with FASB ASC 740 Income Taxes (“ASC 740”). Under ASC 740, tax expense includes U.S. and international income taxes plus the provision for U.S. taxes on undistributed earnings of international subsidiaries not deemed to be permanently invested. Tax credits and other incentives reduce tax expense in the year the credits are claimed. Certain items of income and expense are not reported in tax returns and financial statements in the same year. The tax effect of such temporary differences is reported in deferred income taxes. Deferred tax assets are recognized if it is more likely than not that the assets will be realized in future years. We establish a valuation allowance for deferred tax assets for which realization is not more likely than not. Significant judgment is required in determining our worldwide provision for income taxes and recording the related assets and liabilities. In the ordinary course of our business, there are many transactions and calculations where the ultimate tax determination is less than certain. We and our subsidiaries are examined by various Federal, State, and foreign tax authorities. We regularly assess the potential outcomes of these examinations and any future examinations for the current or prior years in determining the adequacy of our provision for income taxes. We continually assess the likelihood and amount of potential adjustments and record any necessary adjustments in the period in which the facts that give rise to a revision become known. Investment tax credits are accounted for by the flow-through method, which results in recognition of the benefit in the year in which the credit become available. We account for global intangible low-taxed income (“GILTI”) tax in the period in which it is incurred. The GILTI provisions require entities to include in its U.S. income tax return foreign subsidiary earnings in excess of an allowable return on the foreign subsidiaries’ tangible assets.
Treasury Stock	Treasury Stock Common stock purchased for treasury is recorded at cost. At the date of subsequent reissue, the treasury stock account is reduced by the cost of such stock on the weighted-average cost basis.
Foreign Currency Translation	Foreign Currency Translation Foreign currency translation gains and losses and the effect of exchange rate changes on transactions designated as hedges of net foreign investments are included as a component of other comprehensive income (loss). Transaction gains and losses are included in income in the period in which they occur.
Revenue Recognition	Revenue Recognition We recognize revenue, or net sales, in accordance with ASU No. 2014-09, Revenue from Contracts with Customers. Our revenue is earned primarily from the manufacture and sale of engineered materials (“product sales”). Revenue is earned pursuant to contracts, supply agreements and other arrangements with a wide variety of customers. Our performance obligation is to produce a specified product according to technical specifications and, in substantially all instances, to deliver the product. Revenue from product sales is earned at a point in time. We recognize revenue on product sales when we have satisfied our performance obligation and control of the product has passed to the customer thereby entitling us to payment. With respect to substantially all arrangements for product sales, this is deemed to occur when title transfers in accordance with specified shipping terms. Selling prices are fixed at the time the sales arrangement is entered into and payment terms are customary for similar arrangements in our industry. Many of our agreements include customary provisions for volume rebates, discounts and similar incentives. In addition, we are obligated for products that fail to meet agreed upon specification. Provisions for such items are estimated and recorded as sales deductions in the period in which the related revenue is recognized. Refer to Note 8 – “ Revenue ” for additional information about the disaggregation of our net sales.
Environmental Liabilities	Environmental Liabilities Accruals for losses associated with environmental obligations are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated based on existing legislation and remediation technologies. These accruals are adjusted periodically as assessment and remediation actions continue and/or further legal or technical information develops. Such liabilities are exclusive of any insurance or other
Earnings Per Share	Earnings Per Share Basic earnings (loss) per share is computed by dividing net income (loss) by the weighted-average common shares outstanding during the respective periods. Diluted earnings per share is computed by dividing net income by the weighted-average common shares and common share equivalents outstanding during the period. In periods in which there is a net loss, diluted loss per share is equal to basic loss per share. The dilutive effect of common share equivalents is considered in the diluted earnings per share computation using the treasury stock method.
Financial Derivatives and Hedging Activities	Financial Derivatives and Hedging Activities We use financial derivatives to manage exposure to changes in foreign currencies and interest rates. In accordance with FASB ASC 815 Derivatives and Hedging (“ASC 815”), we record all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether we have elected to designate a derivative in a hedging relationship and apply hedge accounting, and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. The gain or loss on those derivative instruments designated and qualifying as a hedge of the exposure to variability in expected future cash flows related to forecasted transactions is deferred and reported as a component of accumulated other comprehensive income (loss). Deferred gains or losses are reclassified to our results of operations at the time the hedged forecasted transaction is recorded in our results of operations. The effectiveness of cash flow hedges is assessed at inception and quarterly thereafter. If the instrument matures, is de-designated, becomes ineffective or it becomes probable that the originally forecasted transaction will not occur, the related change in fair value of the derivative instrument is also reclassified from accumulated other comprehensive income (loss) and recognized in earnings. For additional information, refer to Note 22 - " Financial Derivatives and Hedging Activities. "
Fair Value of Financial Instruments	Fair Value of Financial Instruments Under the accounting for fair value measurements and disclosures, a fair value hierarchy was established that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). A financial instrument's level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The three levels of the fair value hierarchy are described below: Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Level 2 - Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates); and inputs that are derived principally from or corroborated by observable market data by correlation or other means. Level 3 - Inputs that are both significant to the fair value measurement and unobservable.
Employee Retention Tax Credit	Employee Retention Tax Credit The Coronavirus Aid, Relief, and Economic Security Act of 2020 (“CARES”) and the subsequent related amendments provided a refundable payroll tax credit for eligible wages paid to employees in 2020 and 2021
