Accounting Policies [Abstract]
Significant Accounting Policies	Note 1 — Significant Accounting Policies Nature of Operations Hexcel Corporation and its subsidiaries (herein referred to as “Hexcel”, “the Company”, “we”, “us”, or “our”), is a global leader in advanced lightweight composites technology. We propel the future of flight, energy generation, transportation, and recreation through excellence in providing innovative high-performance material solutions that are lighter, stronger and tougher, helping to create a better world for us all. Our broad product range includes carbon fiber, specialty reinforcements, prepregs and other fiber-reinforced matrix materials, honeycomb, resins, engineered core and composite structures for use in commercial aerospace, space and defense, and industrial applications. We serve international markets through manufacturing facilities, sales offices and representatives located in the Americas, Europe, Asia Pacific, India, and Africa. We also have a presence in Malaysia where we are a partner in a joint venture which manufactures composite structures for Commercial Aerospace applications. Principles of Consolidation The accompanying consolidated financial statements include the accounts of Hexcel Corporation and its subsidiaries after elimination of all intercompany accounts, transactions, and profits. At December 31, 2022, we had a 50 % equity ownership investment in the joint venture described above which is accounted for using the equity method of accounting. Basis of Presentation The accompanying consolidated financial statements have been prepared by us pursuant to the rules and regulations of the U.S. Securities and Exchange Commission ("SEC") and are in conformity with U.S. generally accepted accounting principles ("GAAP"). Our fiscal year end is December 31. Unless otherwise stated, all years and dates refer to our fiscal year. In November 2020, we closed our wind energy prepreg production facility in Windsor, Colorado and as a result, certain plant assets to be sold have been recorded in “Assets held for sale” in the Consolidated Balance Sheets at both December 31, 2022 and 2021. During the year ended December 31, 2022, we reduced the carrying value of the Windsor facility by approximately $ 3 million which was recorded in "Other operating (income) expense" on the Consolidated Statements of Operations. Use of Estimates Preparation of the accompanying consolidated financial statements and related disclosures 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, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Cash and Cash Equivalents Cash and cash equivalents include cash on hand and all highly liquid investments with an original maturity of three months or less when purchased. Our cash equivalents are held in prime money market investments with strong sponsor organizations which are monitored on a continuous basis. Inventories Inventories are stated at the lower of cost or net realizable value, with cost determined using the average cost methods. Inventory is reported at its estimated net realizable value based upon our historical experience with inventory becoming obsolete due to age, changes in technology and other factors. Inventory cost consists of materials, labor, and manufacturing related overhead associated with the purchase and production of inventories. Property, Plant and Equipment Property, plant and equipment, including capitalized interest applicable to major project expenditures, is recorded at cost. Asset and accumulated depreciation accounts are eliminated for dispositions, with resulting gains or losses reflected in earnings. Depreciation of plant and equipment is provided generally using the straight-line method over the estimated useful lives of the various assets. The estimated useful lives range from 10 to 40 years for buildings and improvements and from 3 to 25 years for machinery and equipment. Repairs and maintenance are expensed as incurred, while major replacements and betterments are capitalized and depreciated over the remaining useful life of the related asset. Leases The Company regularly enters into operating leases for certain buildings, equipment, parcels of land, and vehicles and accounts for such leases under the provisions of Accounting Standards Codification (“ASC”) 842, accounting for leases. Accordingly, we capitalize all agreements with terms for more than one year, where a right of use asset was identified. Generally, amounts capitalized represent the present value of minimum lease payments over the term, and the duration is equivalent to the base agreement, however, management uses certain assumptions when determining the value and duration of leases. These assumptions include, but are not limited to, the probability of renewing a lease term, certain future events impacting lease payments, as well as fair values not explicit in an agreement. Such assumptions impacted the duration of many of our building leases, as well as certain of our equipment leases. In addition, we elected certain expedients, such as the election to capitalize lease and non-lease components of an agreement as a single component for purposes of simplicity, with the exception of those related to equipment and machinery. In determining the lease renewal, management considers the need and ability to substitute a given asset, as well as certain conditions such as related contractual obligations to our customers (i.e., a contractual obligation of a customer requiring certain manufacturing proximities). In determining fair value, management considers the stand-alone value of an asset in an ordinary market as well as incurring certain costs to terminate an agreement. Most of our leases do not include variable payments but contain scheduled escalations. Any lease payments tied to certain future indexes are adjusted on a go forward basis as those indexes become known. Goodwill and Other Intangible Assets Goodwill represents the excess of the purchase price over the fair value of the identifiable net assets of an acquired business. Goodwill is tested for impairment at the reporting unit level annually, in the fourth quarter, or when events or changes in circumstances indicate that goodwill might be impaired. The Company performed a qualitative assessment (“Step Zero”) and determined that it was more likely than not that the fair values of our reporting units were not less than their carrying values and it was not necessary to perform a quantitative goodwill impairment test. We amortize the cost of other intangibles over their estimated useful lives unless such lives are deemed indefinite. We have indefinite lived intangible assets which are not amortized but are tested annually for impairment during the fourth quarter of each year, or when events or changes in circumstances indicate the potential for impairment. If the carrying amount of the indefinite lived intangible exceeds the fair value, it is written down to its fair value, which is calculated using a discounted cash flow model. Impairment of Long-Lived Assets The Company reviews long-lived assets, including property, plant and equipment and definite-lived intangible assets, for impairment whenever changes in circumstances or events may indicate that the carrying amounts are not recoverable. These indicators include, but are not limited to: a significant decrease in the market price of a long-lived asset, a significant change in the extent or manner in which a long-lived asset is used or its physical condition, a significant adverse change in legal factors or business climate that could affect the value of a long-lived asset, an accumulation of costs significantly in excess of the amount expected for the acquisition or construction of a long-lived asset, a current period operating or cash flow loss combined with a history of losses associated with a long-lived asset and a current expectation that, more likely than not, a long-lived asset will be sold or otherwise disposed of significantly before the end of its previously estimated life. Software Development Costs Costs incurred to develop software for internal use are accounted for under ASC 350-40, “Internal-Use Software.” All costs relating to the preliminary project stage and the post-implementation/operation stage are expensed as incurred. Costs incurred during the application development stage are capitalized and amortized over the useful life of the software, which can range from three to ten years . The amortization of capitalized costs commences after the software has been tested and is placed into operations. Debt Financing Costs Debt financing costs are deferred and amortized to interest expense over the life of the related debt. We capitalize financing fees related to our revolving credit facility and record them as a non-current asset in our Consolidated Balance Sheets. Financing fees related to our bonds and notes are capitalized and recorded as a non-current contra liability in our Consolidated Balance Sheets. See Note 6, Debt, for further information on debt financing costs. Share-Based Compensation The fair value of Restricted Stock Units (“RSUs”) is equal to the market price of our stock at date of grant and is amortized to expense ratably over the vesting period. Performance restricted stock units (“PRSUs”) are a form of RSUs in which the number of shares ultimately received depends on the extent to which we achieve a specified performance target. The fair value of the PRSU is based on the closing market price of the Company’s common stock on the date of grant and is amortized straight-line over the total vesting period. A change in the performance measure expected to be achieved is recorded as an adjustment in the period in which the change occurs. We use the Black-Scholes model to calculate the fair value for all stock option grants, based on the inputs relevant on the date granted, such as the market value of our shares, prevailing risk-free interest rate, etc. The value of the portion of the award, after considering potential forfeitures, that is ultimately expected to vest is recognized as expense in our consolidated statements of operations on a straight-line basis over the requisite service periods. The value of RSUs, PRSUs and non-qualifying options awards for retirement eligible employees is expensed on the grant date as they are fully vested. Currency Translation The assets and liabilities of international subsidiaries are translated into U.S. dollars at year-end exchange rates, and revenues and expenses are translated at average exchange rates during the year. Cumulative currency translation adjustments are included in “accumulated other comprehensive loss” in the stockholders’ equity section of the Consolidated Balance Sheets. Revenue Recognition Revenue is predominately derived from a single performance obligation under long-term agreements with our customers and pricing is fixed and determinable. The majority of our revenue is recognized at a point in time when the customer has obtained control of the product. We have determined that individual purchase orders (“PO”), whose terms and conditions taken with a master agreement, create the revenue contracts which are generally short-term in nature. For those sales which are not tied to a long-term agreement, we generate a PO that is subject to our standard terms and conditions. Revenue is recognized over time for customer contracts that contain a termination for convenience clause (“T for C") and where the products produced do not have an alternative use. For revenue recognized over time, we estimate the amount of revenue earned at a given point during the production cycle based on certain costs factors such as raw materials and labor incurred to date, plus a reasonable profit, which is known as the cost-to-cost input method. Our revenue recognition policy recognizes the following practical expedients allowed under ASC 606: • Payment terms with our customers which are one year or less, are not considered a performance obligation. • Shipping and handling fees and costs incurred in connection with products sold are recorded in cost of sales in our Consolidated Statements of Operations and are not considered a performance obligation to our customers. • Our performance obligations on our orders are generally satisfied within one year from a given reporting date therefore we omit disclosure of the transaction price allocated to remaining performance obligations on open orders. Product Warranty We provide for an estimated amount of product warranty at the point a claim is probable and estimable. This estimated amount is provided by product and based on current facts, circumstances, and historical warranty experience. Research and Technology Significant costs are incurred each year in connection with research and technology (“R&T”) programs that are expected to contribute to future earnings. Such costs are related to the development and, in certain instances, the qualification and certification of new and improved products and their uses. R&T costs are expensed as incurred. Income Taxes We provide for income taxes using the asset and liability approach . Under this approach, deferred income tax assets and liabilities reflect tax net operating loss and credit carryforwards and the tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting and income tax purposes. Deferred tax assets require a valuation allowance when it is not more likely than not, based on the evaluation of positive and negative evidence, that the deferred tax assets will be realized. The realization of deferred tax assets is dependent upon the timing and magnitude of future taxable income prior to the expiration of the deferred tax assets’ attributes. When events and circumstances so dictate, we evaluate the realizability of our deferred tax assets and the need for a valuation allowance by forecasting future taxable income. Investment tax credits are recorded on a flow-through basis, which reflects the credit in net income as a reduction of the provision for income taxes in the same period as the credit is realized for federal income tax purposes. In addition, we recognize interest accrued related to unrecognized tax benefits as a component of interest expense and penalties as a component of income tax expense in the Consolidated Statements of Operations. Concentration of Credit Risk Financial instruments that potentially subject us to significant concentrations of credit risk consist primarily of trade accounts receivable. Two customers and their related subcontractors accounted for approximately 51 % of our annual net sales in 2022, 49 % in 2021 and 52 % in 2020. Refer to Note 18 for further information on significant customers. We perform ongoing credit evaluations of our customers’ financial condition but generally do not require collateral or other security to support customer receivables. We establish an allowance for doubtful accounts based on factors surrounding the credit risk of specific customers, historical trends, and other financial information. Derivative Financial Instruments We use various financial instruments, including foreign currency forward exchange contracts, commodity, and interest rate agreements, to manage our exposure to market fluctuations by generating cash flows that offset, in relation to their amount and timing, the cash flows of certain foreign currency denominated transactions, commodities or underlying debt instruments. We mark our foreign exchange forward contracts to fair value. When the derivatives qualify, we designate our foreign currency forward exchange contracts as cash flow hedges against forecasted foreign currency denominated transactions and report the changes in fair value of the instruments in “accumulated other comprehensive loss” until the underlying hedged transactions affect income. We designate our interest rate agreements as fair value or cash flow hedges against specific debt instruments and recognize interest differentials as adjustments to interest expense as the differentials may occur; the fair value of the interest rate swaps is recorded in other assets or other non-current liabilities with a corresponding amount to “accumulated other comprehensive loss”. We do not use financial instruments for trading or speculative purposes. In accordance with accounting guidance, we recognize all derivatives as either assets or liabilities on our Consolidated Balance Sheets and measure those instruments at fair value. Self-insurance We are self-insured up to specific levels for certain medical and health insurance and workers’ compensation plans. Accruals are established based on actuarial assumptions and historical claim experience and include estimated amounts for incurred but not reported claims. Recently Enacted Government Legislation On August 16, 2022, the U.S. enacted the Inflation Reduction Act (the "IRA") of 2022. The IRA contains a number of tax provisions including a new corporate alternative minimum tax, an excise tax on stock buybacks, and incentives for energy and climate initiatives. These provisions are effective for taxable years beginning after December 31, 2022. Currently, we do not qualify for the corporate alternative minimum tax. The impact of the excise tax will be dependent on the extent of share repurchases made in future periods. We are assessing the applicability and impact to Hexcel of incentives for energy and climate initiatives.

The maturity of the Facility is June 2024 . The refinancing provides for a reduction in interest costs, as well as less restrictive covenants. The Facility agreement contains financial and other covenants, including, but not limited to customary restrictions on the incurrence of debt by our subsidiaries and the granting of liens, as well as the maintenance of an interest coverage ratio and a leverage ratio. As defined in the Facility agreement, we are required to maintain a minimum interest coverage ratio of 3.50 (based on the ratio of earnings before interest tax depreciation and amortization, “EBITDA”, to interest expense). In addition, the maximum leverage ratio must not exceed 3.75 (based on the ratio of total debt to EBITDA) with a step up to 4.25 allowed following certain acquisitions. The Facility agreement contains other customary terms and conditions such as representations and warranties, additional covenants and events of default. As of December 31, 2022, total borrowings under the Facility were $ 25 million. The Facility agreement permits us to issue letters of credit up to an aggregate amount of $ 50 million. Outstanding letters of credit reduce the amount available for borrowing under the Facility. As of December 31, 2022, there were no issued le tters of credit under the Facility, resulting in undrawn availability under the Facility of $ 725 million. The weighted average interest rate for the Facility was 4.7 % for the year ended December 31, 2022. The balance of unamortized deferred financing costs related to the Facility was $ 0.8 million at December 31, 2022 and $ 1.7 m illion at December 31, 2021. In September 2020, we amended the Facility to allow for relief from certain terms, including adjusting the maximum leverage ratio covenant for a defined period. On January 28, 2021, we further amended the Facility agreement (the “Second Amendment”) to provide that, from January 28, 2021 through and including March 31, 2022, we would not be subject to a maximum leverage ratio covenant but instead be required to maintain Liquidity (as defined in the Facility agreement) of at least $ 250 million. Additionally, during such period, the Company was subject to limitations on share repurchases, cash dividends, and its ability to incur secured debt, in each case subject to certain exceptions; the applicable margin and commitment fees would be increased; the incremental facility would not be available; and if the Company’s public debt rating was downgraded to (i) BB or lower by Standard & Poor’s and (ii) Ba2 or lower by Moody’s, we would be required to grant liens on certain of our assets, which liens would be released upon the Company’s public debt rating being upgraded to BB+ or higher by Standard & Poor’s or Ba1 or higher by Moody’s . In addition, the Second Amendment provided that the Company would not be subject to an interest coverage ratio covenant until the test period ending December 31, 2021 and revolving commitments under the Facility we re reduced from $ 1 billion to $ 750 million. As of April 1, 2022, the original terms and conditions to the Facility agreement were reinstated except that the amount of the lender's commitment remained at $ 750 million. Share repurchases restrictions that had been in effect per the Second Amendment expired on March 31, 2022. As of December 31, 2022, we were in compliance with all debt covenants . 3.95% Senior Notes In 2017, the Company issued $ 400 million in aggregate principal amount of 3.95 % Senior Unsecured Notes due in 2027 . The interest rate on these senior notes may be increased by 0.25 % each time a credit rating applicable to the notes is downgraded. The maximum rate is 5.95 %. The effective interest rate for 2022 was 4.11 % inclusive of approximately a 0.25 % benefit of treasury locks. The fair value of the senior notes due in 2027 based on quoted prices utilizing Level 2 inputs (as defined in Note 19) was $ 370.8 million at December 31, 2022. The balance of unamortized deferred financing costs and debt discount related to the senior notes was $ 2.2 million at December 31, 2022 and $ 2.8 million at December 31, 2021. 4.7% Senior Notes In 2015, the Company issued $ 300.0 million in aggregate principal amount of 4.7 % Senior Unsecured Notes due in 2025 . The interest rate on these senior notes may be increased by 0.25 % each time a credit rating applicable to the notes is downgraded. The maximum rate is 6.7 %. The effective interest rate for 2022 was 5.07 %. The conditions and covenants related to the senior notes are less restrictive than those of our Facility. The fair value of the senior notes based on quoted prices utilizing Level 2 inputs wa s $ 293.3 million at December 31, 2022. The balance for unamortized deferred financing costs and debt discount related to the senior notes was $ 0.9 million at December 31, 2022 and $ 1.3 million at December 31, 2021.

Leases [Abstract]
Leases	Note 7 — Leases At December 31, 2022, we had approximately $ 49.6 million of right of use assets recorded in non-current other assets, and $ 49.6 million of related liabilities, $ 39.4 million of which was included in other non-current liabilities with the current portion of $ 10.2 million included in accrued liabilities. The weighted average of the remaining lease terms was approximately 7 years. We discount the future lease payments of our leases using the prevailing rates extended to us by our lenders relevant to the period of inception. These rates are comprised of LIBOR plus a stated spread less a component related to collateralization. The rates are relative to the duration of the lease at inception and the country of origin. The weighted average interest rate used in calculating the fair values listed above was 3.3 %. The following table lists the schedule of future undiscounted cash payments related to right of use assets by year: (In millions) 2023 $ 10.2 2024 9.6 2025 7.5 2026 7.0 2027 6.8 Thereafter 16.5 Total lease payments 57.6 Less: Imputed interest ( 8.0 ) Present value of lease payments $ 49.6 Operating lease expense recognized during the year ended December 31, 2022, 2021 and 2020, wa s $ 15.2 million, $ 15.3 million and $ 16.2 million, respectively.

Retirement and Other Postretire

Retirement and Other Postretirement Benefit Plans	12 Months Ended

Retirement Benefits [Abstract]
Retirement and Other Postretirement Benefit Plans	Note 8 — Retirement and Other Postretirement Benefit Plans We maintain qualified defined benefit retirement plans covering certain current and former European employees, as well as nonqualified defined benefit retirement plans, and retirement savings plans covering certain eligible U.S. and European employees and participate in a union sponsored multi-employer pension plan covering certain U.S. employees with union affiliations. In addition, we provide certain postretirement health care and life insurance benefits to eligible U.S. retirees. Accounting standards require the use of certain assumptions, such as the expected long-term rate of return, discount rate, rate of compensation increase, healthcare cost trend rates, and retirement and mortality rates, to determine the net periodic costs of such plans. These assumptions are reviewed and set annually at the beginning of each year. In addition, these models use an “attribution approach” that generally spreads individual events, such as plan amendments and changes in actuarial assumptions, over the service lives of the employees in the plan. That is, employees render service over their service lives on a relatively smooth basis and therefore, the income statement effects of retirement and postretirement benefit plans are earned in, and should follow, the same pattern. We use our actual return experience, future expectations of long-term investment returns, and our actual and targeted asset allocations to develop our expected rate of return assumption used in the net periodic cost calculations of our funded European defined benefit retirement plans. Due to the difficulty involved in predicting the market performance of certain assets, there will be a difference in any given year between our expected return on plan assets and the actual return. Following the attribution approach, each year’s difference is amortized over a number of future years. Over time, the expected long-term returns are designed to approximate the actual long-term returns and therefore result in a pattern of income and expense recognition that more closely matches the pattern of the services provided by the employees. We annually set our discount rate assumption for retirement-related benefits accounting to reflect the rates available on high-quality, fixed-income debt instruments. The rate of compensation increases for nonqualified pension plans, which is another significant assumption used in the actuarial model for pension accounting, is determined by us based upon our long-term plans for such increases and assumed inflation. For the postretirement health care and life insurance benefits plan, we review external data and its historical trends for health care costs to determine the health care cost trend rates. Retirement and termination rates are based primarily on actual plan experience. The mortality table used for the U.S. plans is based on the Pri-2012 White Collar Healthy Annuitant Mortality Table with Improvement Scale MP-2021 and for the U.K. Plan the S2PXA base table with future improvements in line with the CMI 2021 projection model with a long-term trend rate of 1.25 % p. a. Actual results that differ from our assumptions are accumulated and amortized over future periods and therefore, generally affect the net periodic costs and recorded obligations in such future periods. While we believe that the assumptions used are appropriate, significant changes in economic or other conditions, employee demographics, retirement and mortality rates, and investment performance may materially impact such costs and obligations. U.S. Defined Benefit Retirement Plans We have nonqualified defined benefit retirement plans covering certain current and former U.S. employees that are funded as benefits are incurred. Under the provisions of these plans, we expect to contribute approximately $ 0.7 million in 2023 to cover unfunded benefits. Multi-Employer Plan The Company is party to a multi-employer pension plan covering certain U.S. employees with union affiliations. The plan is the Western Metal Industry Pension Fund, (“the Plan”). The Plan’s employer identification number is 91-6033499; the Plan number is 001. In 2022, 2021 and 2020 the Plan reported Hexcel Corporation as being an employer that contributed greater than 5 % of the Plan’s total contributions. The collective bargaining agreement was renewed on November 20, 2020 retroactively to October 1, 2020 for a five-year term. The Plan has been listed in “critical status” and has been operating in accordance with a Rehabilitation Plan since 2010. The Plan, as amended under the Rehabilitation Plan, reduced the adjustable benefits of the participants, and levied a surcharge on employer contributions. The Company contributed $ 1.5 million in 2022, $ 2.1 million in 2021 and $ 2.0 million in 2020. We expect the Company’s contribution to be approxi mately $ 1.5 m illion in 2023 and remain at that level over the remaining term. U.S. Retirement Savings Plan Under the retirement savings plan, eligible U.S. employees can contribute up to 75 % of their annual compensation to an individual 401(k) retirement savings account. The Company makes matching contributions equal to 50 % of employee contributions, not to exceed 3 % of employee compensation each year. We also contribute an additional 2 % to 4 % of each eligible U.S. employee’s salary to an individual 401(k) retirement savings account. This increases the maximum contribution to individual U.S. employee savings accounts to between 5 % and 7 % per year before any profit-sharing contributions that are made when we meet or exceed certain performance targets that are set annually. These profit-sharing contributions are made at the Company’s discretion and are targeted at 3 % of an eligible U.S. employee’s pay, with a maximum of 4.5 %. In April 2020, the matching contributions were suspended as a result of the impact of COVID-19 impact, however, as of January 1, 2021 they were reinstated for all eligible employees . U.S. Postretirement Plans In addition to defined benefit and retirement savings plan benefits, we also provide certain postretirement health care and life insurance benefits to eligible U.S. retirees. Depending upon the plan, benefits are available to eligible employees who retire after meeting certain age and service requirements and were employed by Hexcel as of February 1996. Our funding policy for the postretirement health care and life insurance benefit plans is generally to pay covered expenses as they are incurred. Under the provisions of these plans, we expect to contribute approximate ly $ 0.2 mill ion in 2023 to cover unfunded benefits. Non-Qualified Deferred Compensation Plan Under the deferred compensation plan, eligible U.S. employees may make tax-deferred contributions that cannot be made under the 401(k) Plan because of Internal Revenue Service limitations. We match 50 % of a participant’s contributions up to 6 % of the participants excess compensation pay as well as provide the same fixed and profit-sharing contributions as provided under the 401(k) plan. In April 2020, the matching contributions were suspended as a result of the impact of COVID-19, however, as of January 1, 2021 they have been reinstated for all eligible employees. We have elected to fund our deferred compensation obligation through a rabbi trust. The rabbi trust is subject to creditor claims in the event of insolvency, but the assets held in the rabbi trust are not available for general corporate purposes. Amounts in the rabbi trust are invested in a number of funds based on the funds available under our 401(k) plan, other than the Hexcel stock fund. The securities are carried at fair value and are included in other assets on the Consolidated Balance Sheets. We record trading gains and losses in general and administrative expenses on the Consolidated Statements of Operations, along with the offsetting amount related to the increase or decrease in deferred compensation to reflect our exposure to liabilities for payment under the deferred compensation plan. European Defined Benefit Retirement Plans We have defined benefit retirement plans in the United Kingdom, Belgium, France, and Austria covering certain employees of our subsidiaries in those countries. The defined benefit plan in the United Kingdom (the “U.K. Plan”), the largest of the European plans, was terminated in 2011 and replaced with a defined contribution plan. The total assets in the U.K. Plan were held in a variety of investments. Equity investments and growth fund investments are made with the objective of achieving a return on plan assets consistent with the funding requirements of the plan, maximizing portfolio return and minimizing the impact of market fluctuations on the fair value of the plan assets. In 2021, the plan bought insurance policies through the same insurer, referred to as a buy-in, which immunized the full amount of the liability. Liability driven investments are made to further reduce balance sheet volatility. As a result of an annual review of historical returns and market trends, and the insurance policy, the expected long-term weighted average rate of return for the U.K. Plan for the 2023 plan year will be 0.95 % and 3.0 % for the other European plans as a group. U.K. Defined Contribution Pension Plan Under the Defined Contribution Plan, eligible U.K. employees can belong to the Deferred Contribution Plan on a non-participatory basis or can elect to contribute 3 %, 5 % or 7 % of their pensionable salary. The Company will contribute 5 %, 9 % and 13 % respectively. The plan also provides life insurance and disability insurance benefits for members. Retirement and Other Postretirement Plans – France The employees of our French subsidiaries are entitled to receive a lump-sum payment upon retirement subject to certain service conditions under the provisions of the national chemicals and textile workers collective bargaining agreements. The amounts attributable to the French plans have been included within the total expense and obligation amounts noted for the European plans. Net Periodic Pension Expense Net periodic expense for our U.S. and European qualified and nonqualified defined benefit pension plans and our retirement savings plans for the three years ended December 31, 2022 is detailed in the table below.

The measurement date used to determine the benefit obligations and plan assets of the defined benefit retirement and postretirement plans was December 31, 2022. All costs related to our pensions are included as a component of operating income in our Consolidated Statements of Operations. For the years ended December 31, 2022, 2021 and 2020 amounts unrelated to service costs were a benefit of $ 2.4 million, $ 0.1 million and $ 3.1 million, respectively. The total accumulated benefit obligation (“ABO”) for the U.S. defined benefit retirement plans was $ 19.8 million and $ 23.6 million as of December 31, 2022 and 2021, respectively. Excluding the U.K. Plan, the European plans’ ABO exceeded plan assets as of December 31, 2022 and 2021 by $ 12.2 million and $ 16.1 million, respectively. The ABO for these plans was $ 16.3 million and $ 20.7 million as of December 31, 2022 and 2021, respectively. The U.K. Plan is overfunded; the ABO of this plan was $ 112.3 million and $ 219.9 million at December 31, 2022 and 2021 respectively. The fair value of the U.K. Plan assets was $ 117.9 million and $ 226.8 million at December 31, 2022 and 2021, respectively.

This provides protection against interest rate movements, inflation, market fluctuations as well as member longevity. Insurance contracts outside of the U.K. contain a minimum guaranteed return. The insurance contracts are Level 3 investments and are valued using unobservable inputs that are based on the best information available. The fair value of the assets is equal to the total amount of all individual technical reserves plus the non-allocated employer’s financing fund reserves at the valuation date. The individual technical and financing fund reserves are equal to the accumulated paid contributions taking into account the insurance tariffication and any allocated profit-sharing return. The index-linked gilt allocation provides a partial interest rate and inflation rate hedge against the valuation of the liabilities. The diversified investment funds represent plan assets invested in a Pensionskasse (an Austrian multi-employer pension fund). The main holdings consist of equity, bonds, real estate and bank deposits. The actual allocations for the pension assets at December 31, 2022 and 2021, and target allocations by asset class, are as follows: Percentage Target Percentage Target of Plan Assets Allocations of Plan Assets Allocations Asset Class 2022 2022 2021 2021 Diversified growth funds 5.2 % 5.2 % 3.4 % 3.4 % Index linked gilts 0.6 0.6 0.6 0.6 Diversified investment funds 1.5 1.5 1.0 1.0 Insurance contracts 92.5 92.5 94.2 94.2 Cash and cash equivalents 0.2 0.2 0.8 0.8 Total 100 % 100 % 100 % 100 % Assumptions The assumed discount rate for pension plans reflects the market rates for high-quality fixed income debt instruments currently available. A third party provided standard yield curve was used for the U.S. non-qualified and postretirement plans. For the U.K. Plan, cash flows were not available and therefore we considered the derived yield to market on a representative bond of suitable duration taken from the third-party provider’s synthetic bond yield curve. We believe that the timing and amount of cash flows related to these instruments is expected to match the estimated defined benefit payment streams of our plans. The assumed discount rate for the U.S. non-qualified plans uses individual discount rates for each plan based on their associated cash flows. Salary increase assumptions are based on historical experience and anticipated future management actions. For the postretirement health care and life insurance benefit plans, we review external data and our historical trends for health care costs to determine the health care cost trend rates. Retirement rates are based primarily on actual plan experience and on rates from previously mentioned mortality tables. Actual results that differ from our assumptions are accumulated and amortized over future periods and therefore, generally affect the net periodic costs and recorded obligations in such future periods. While we believe that the assumptions used are appropriate, significant changes in economic or other conditions, employee demographics, retirement and mortality rates, and investment performance may materially impact such costs and obligations. Assumptions used to estimate the actuarial present value of benefit obligations at December 31, 2022, 2021 and 2020 are shown in the following table. These year-end values are the basis for determining net periodic costs for the following year. 2022 2021 2020 U.S. defined benefit retirement plans: Discount rates 5.0 % - 5.1 % 1.0 % - 2.4 % 0.4 % - 1.8 % Rate of increase in compensation 3 % 3 % 3 % European defined benefit retirement plans: Discount rates 3.1 % - 3.95 % 0.3 % - 0.95 % 0.00 % - 1.45 % Rates of increase in compensation 3.2 %- 3.5 % 3.0 % 2.75 % - 3.0 % Expected long-term rates of return on plan assets 2.0 % – 3.95 % 0.95 % – 3.0 % 1.45 % – 3.0 % Postretirement benefit plans: Discount rates 2.0 % 1.3 % 1.3 % The following table presents the impact that a one-percentage-point increase and a one-percentage-point decrease in the expected long-term rate of return and discount rate would have on the 2022 pension expense, and the impact on our retirement obligation as of December 31, 2022 for a one-percentage-point change in the discount rate: U.S. Non-Qualified U.S. Retiree U.K. (In millions) Pension Plans Medical Plans Retirement Plan Periodic pension expense One-percentage-point increase: Expected long-term rate of return N/A N/A $ ( 2.1 ) Discount rate $ — $ — $ ( 0.5 ) One-percentage-point decrease: Expected long-term rate of return $ ( 0.1 ) N/A $ 2.1 Discount rate $ 0.1 $ — $ ( 0.1 ) Retirement obligation One-percentage-point increase in discount rate $ ( 0.4 ) $ ( 0.1 ) $ ( 18.1 ) One-percentage-point decrease in discount rate $ 0.4 $ 0.1 $ 22.9 The annual rate of increase in the per capita cost of covered health care benefits is assumed to be 6.5 % for medical rates and are assumed to gradually decline to 4.75 % by 2029 .

Income Tax Disclosure [Abstract]
Income Taxes	Note 9 — Income Taxes Income before income taxes and the provision for income taxes, for the three years ended December 31, 2022, were as follows: (In millions) 2022 2021 2020 Income before income taxes: U.S. $ 110.6 $ 21.7 $ 0.8 International 39.2 0.3 ( 28.5 ) Total income (loss) before income taxes $ 149.8 $ 22.0 $ ( 27.7 ) Income tax expense (benefit): Current: U.S. $ 28.3 $ 5.4 $ ( 11.3 ) International 6.4 3.1 1.7 Current income tax expense (benefit) 34.7 8.5 ( 9.6 ) Deferred: U.S. ( 8.9 ) ( 2.3 ) 0.1 International 5.8 ( 0.3 ) ( 51.5 ) Deferred income tax benefit ( 3.1 ) ( 2.6 ) ( 51.4 ) Total income tax expense (benefit) $ 31.6 $ 5.9 $ ( 61.0 ) A reconciliation of the provision for income taxes at the U.S. federal statutory income tax rate of 21.0 % to the effective income tax rate, for the year ended December 31, 2022, 2021 and 2020 is as follows: (In millions) 2022 2021 2020 Provision (benefit) for taxes at U.S. federal statutory rate $ 31.5 $ 4.6 $ ( 5.8 ) State and local taxes, net of federal benefit 0.6 ( 0.1 ) ( 4.2 ) Foreign effective rate differential 1.5 0.7 ( 1.9 ) Tax credits ( 4.3 ) ( 3.5 ) ( 3.0 ) Change in valuation allowance 0.7 0.7 ( 39.5 ) Remeasurement of deferred taxes 0.7 1.4 3.5 Excess tax benefits on stock-based compensation ( 0.2 ) ( 0.2 ) ( 0.9 ) Other 1.6 2.6 ( 4.3 ) Decrease in reserves for uncertain tax positions ( 0.5 ) ( 0.3 ) ( 4.9 ) Total income tax expense (benefit) $ 31.6 $ 5.9 $ ( 61.0 ) We do no t provide for additional income or withholding taxes for any undistributed foreign earnings as we do not currently have any specific plans to repatriate funds from our international subsidiaries; however, we may do so in the future if a dividend can be remitted with no material tax impact. As of December 31, 2022, we ha ve approximately $ 814.3 million o f unremitted foreign earnings that we intend to keep indefinitely reinvested. Additionally, due to withholding tax, basis computations and other tax related considerations, it is not practicable to estimate any taxes to be provided on outside basis differences at this time. Deferred Income Taxes Deferred income taxes result from tax attributes including foreign tax credits, net operating loss carryforwards and temporary differences between the recognition of items for income tax purposes and financial reporting purposes. Principal components of deferred income taxes as of December 31, 2022 and 2021 are: (In millions) 2022 2021 Assets Net operating loss carryforwards $ 89.7 $ 93.5 Capital loss carryforward — 1.6 Tax credit carryforwards 9.2 10.3 Stock-based compensation 9.6 7.8 Other comprehensive income 21.4 21.1 Inventory reserves 10.5 11.5 Right of use liability 11.7 12.2 Capitalized research and development expenditures 9.8 — Reserves and other 8.1 8.8 Subtotal 170.0 166.8 Valuation allowance ( 8.3 ) ( 7.6 ) Total assets $ 161.7 $ 159.2 Liabilities Accelerated depreciation ( 179.3 ) ( 188.8 ) Accelerated amortization ( 18.3 ) ( 17.3 ) Right of use asset ( 11.7 ) ( 12.2 ) Post-retirement obligations ( 12.7 ) ( 11.6 ) Other ( 8.2 ) ( 0.2 ) Total liabilities ( 230.2 ) $ ( 230.1 ) Net deferred tax liabilities $ ( 68.5 ) $ ( 70.9 ) Deferred tax assets and deferred tax liabilities as presented in the Consolidated Balance Sheets as of December 31, 2022 and 2021 are as follows and are recorded in other assets and deferred income taxes in the Consolidated Balance Sheets: (In millions) 2022 2021 Long-term deferred tax assets, net $ 57.9 $ 69.1 Long-term deferred tax liability, net ( 126.4 ) ( 140.0 ) Net deferred tax liabilities $ ( 68.5 ) $ ( 70.9 ) The deferred tax assets for the respective periods were assessed for recoverability and, where applicable, a valuation allowance was recorded to reduce the total deferred tax asset to an amount that will, more likely than not, be realized in the future. The valuation allowance as of December 31, 2022 relates to certain U.S. and foreign tax attributes for which we have determined, based upon historical results and projected future book and taxable income levels, that a valuation allowance should continue to be maintained. The valuation allowance increased by $ 0.7 million in 2022 primarily based on the current year movement of U.S. and foreign tax attributes. The valuation allowance as of December 31, 2021 related primarily to certain U.S. tax attributes for which we have determined, based upon historical results and projected future book and taxable income levels, that a valuation allowance should continue to be maintained. The net change in the total valuation allowance for both years ended December 31, 2022 and 2021, was an increase of $ 0.7 million. Although realization is not assured, we have concluded that it is more likely than not that the deferred tax assets, for which a valuation allowance was determined to be unnecessary, will be realized in the ordinary course of operations based on the available positive and negative evidence, including scheduling of deferred tax liabilities and projected income from operating activities. The amount of the net deferred tax assets considered realizable, however, could be reduced in the near term if actual future income or income tax rates are lower than estimated, or if there are differences in the timing or amount of future reversals of existing taxable or deductible temporary differences. Net Operating Loss & Tax Credit Carryforwards At December 31, 2022, we had tax credit carryforwards for U.S. and foreign tax purposes of $ 9.2 million available to offset future income taxes. These credits will begin to expire if not utilized in 2023. We also had net operating loss carryforwards for U.S. state and foreign income tax purposes of $ 4.9 million and $ 351.6 million, respectively, for which there were foreign valuation allowances of $ 8.4 million as of December 31, 2022. Our foreign net operating losses can be carried forward without limitation in Belgium, France, Luxembourg, and the U.K. We have a partial valuation allowance against certain foreign net operating losses for which the Company believes it is not more likely than not that the net operating losses will be utilized. Uncertain Tax Positions Our unrecognized tax benefits at December 31, 2022 relate to U.S. federal and various state jurisdictions. The following table summarizes the activity related to our unrecognized tax benefits. Unrecognized Tax Benefits (In millions) 2022 2021 2020 Balance as of January 1, $ 9.7 $ 10.5 $ 18.1 Additions based on tax positions related to the current year 0.2 0.2 0.3 Reductions for tax positions of prior years — — ( 7.9 ) Expiration of the statute of limitations for the assessment of taxes ( 7.4 ) ( 1.0 ) — Balance as of December 31, $ 2.5 $ 9.7 $ 10.5 We had unrecognized tax benefits of $ 2.5 million at December 31, 2022, of which $ 2.5 million, if recognized, would impact our annual effective tax rate. In addition, we recognize interest accrued related to unrecognized tax benefits as a component of interest expense and penalties as a component of income tax expense in the Consolidated Statements of Operations. The Company did not recognize any interest expense or penalties related to the above unrecognized tax benefits in 2022 and 2021. During 2020, we reversed $ 0.2 million of accrued interest related to unrecognized tax benefits. The Company had no accrued interest as of December 31, 2022 and 2021. We are subject to taxation in the U.S. and various states and foreign jurisdictions. The U.S. federal tax returns have been audited through 2016. Foreign and U.S. state jurisdictions have statutes of limitations generally ranging from 3 to 5 years. Years in major jurisdictions that remain open to examination are the U.S. (2019 onward for Federal purposes and 2018 onward for state purposes), Austria (2019 onward), Belgium (2016 onward), France (2019 onward), Spain (2018 onward) and the U.K. (2019 onward). We are currently under examination in certain foreign tax jurisdictions. . As of December 31, 2022, we had uncertain tax positions for which it is reasonably possible that amounts of unrecognized tax benefits could significantly change over the next year. These uncertain tax positions relate to our tax returns from 2014 onward. We believe it is reasonably possible that the total amount of unrecognized tax benefits disclosed as of December 31, 2022 may decrease by approximately $ 0.5 to $ 1.0 million in the fiscal year ending December 31, 2023 due to the expiration of statutes of limitation.

Revenue from Contract with Customer [Abstract]
Revenue	Note 11 — Revenue Our revenue is primarily derived from the sale of inventory under long-term contracts with our customers. The majority of our revenue is recognized at a point in time. In instances where our customers acquire our goods related to government contracts, the contracts are typically subject to terms similar, or equal to, the Federal Acquisition Regulation Part 52.249-2, which contains a termination for convenience clause ("T for C") that requires the customer to pay for the cost of both the finished and unfinished goods at the time of cancellation plus a reasonable profit. We recognize revenue over time for those contracts that have a T for C clause and where the products being produced have no alternative use. As our production cycle is typically nine months or less, it is expected that goods related to the revenue recognized over time will be shipped and billed within the next twelve months. We disaggregate our revenue based on market for analytical purposes. The following table details our revenue by market for the years ended December 31, 2022, 2021 and 2020: (In millions) 2022 2021 2020 Consolidated Net Sales $ 1,577.7 $ 1,324.7 $ 1,502.4 Commercial Aerospace 911.8 668.2 822.3 Space & Defense 465.2 434.9 448.5 Industrial 200.7 221.6 231.6 Revenue recognized over time gives rise to contract assets, which represent revenue recognized but unbilled. Contract assets are included in our Consolidated Balance Sheets as a component of current assets. The activity related to contract assets is as follows: Composite Engineered (In millions) Materials Products Total Opening adjustment - January 1, 2020 $ 12.8 $ 39.9 $ 52.7 Net revenue billed ( 5.0 ) ( 4.6 ) ( 9.6 ) Balance at December 31, 2020 $ 7.8 $ 35.3 $ 43.1 Net revenue billed ( 1.0 ) ( 11.6 ) ( 12.6 ) Balance at December 31, 2021 6.8 23.7 30.5 Net revenue billed 2.3 ( 0.8 ) 1.5 Balance at December 31, 2022 $ 9.1 $ 22.9 $ 32.0 Contract assets as of December 31, 2022, will be billed and reclassified to accounts receivable during 2023.

Options granted generally vest over three years and expire ten years from the date of grant. A summary of option activity under the plan for the three years ended December 31, 2022 is as follows: Number of Weighted- Remaining Options Average Contractual Life (In millions) Exercise Price (in years) Outstanding at December 31, 2019 1.3 $ 47.92 5.6 Options granted 0.5 $ 54.82 0.0 Options exercised ( 0.2 ) $ 32.18 0.0 Outstanding at December 31, 2020 1.6 $ 51.07 6.0 Options granted 0.4 $ 44.90 0.0 Options exercised ( 0.3 ) $ 38.03 0.0 Outstanding at December 31, 2021 1.7 $ 51.28 6.3 Options granted 0.2 $ 52.17 0.0 Options exercised ( 0.1 ) $ 37.99 0.0 Outstanding at December 31, 2022 1.8 $ 52.01 5.7 Year Ended December 31, (In millions, except weighted average exercise price) 2022 2021 Aggregate intrinsic value of outstanding options $ 18.2 $ 10.6 Aggregate intrinsic value of exercisable options $ 11.8 $ 5.9 Total intrinsic value of options exercised $ 1.8 $ 4.5 Total number of options exercisable 1.2 1.0 Weighted average exercise price of options exercisable $ 52.98 $ 51.56 Total unrecognized compensation cost on non-vested options (a) $ 1.7 $ 2.7 (a) Unrecognized compensation cost relates to non-vested stock options and is expected to be recognized over the remaining vesting period ranging from one year to three years . Valuation Assumptions in Estimating Fair Value We estimated the fair value of stock options at the grant date using the Black-Scholes option pricing model with the following assumptions for the years ended December 31, 2022, 2021 and 2020: 2022 2021 2020 Risk-free interest rate 1.74 % 0.58 % 0.85 % Expected option life (in years) 6.03 5.99 5.96 Dividend yield 0.8 % 1.5 % 1.1 % Volatility 44.21 % 49.65 % 44.35 % Weighted-average fair value per option granted $ 21.40 $ 18.12 $ 19.50 The weighted-average expected life is derived from the average midpoint between the vesting and the contractual term and considers the effect of both the inclusion and exclusion of post-vesting cancellations during the ten-year period. Expected volatility is calculated based on a blend of both historic volatility of our common stock and implied volatility of our traded options. We weigh both volatility inputs equally and utilize the average as the volatility input for the Black-Scholes calculation. The risk-free interest rate for the expected term is based on the U.S. Treasury yield curve in effect at the time of grant and corresponding to the expected term. Restricted Stock Units — Service Based As of December 31, 2022, a total of 479,497 shares of service based restricted stock units were outstanding, which vest based on years of service under the 2003 and 2013 incentive stock plans. RSUs are granted to key employees, executives, and directors of the Company. The fair value of the RSU is based on the closing market price of the Company’s common stock on the date of grant and is amortized on a straight-line basis over the requisite service period. The stock-based compensation expense recognized is based on an estimate of shares ultimately expected to vest, and therefore it has been reduced for estimated forfeitures. The total compensation expense related to awards granted to retirement-eligible employees is recognized on the grant date. The table presented below provides a summary of the Company’s RSU activity for the years ended December 31, 2022, 2021 and 2020: RSUs Weighted-Average Number of (In millions) Fair Value Grant Date Outstanding at December 31, 2019 0.4 $ 48.06 RSUs granted 0.2 $ 51.51 RSUs issued ( 0.1 ) $ 51.82 Outstanding at December 31, 2020 0.5 $ 47.98 RSUs granted 0.1 $ 47.20 RSUs issued ( 0.1 ) $ 48.61 Outstanding at December 31, 2021 0.5 $ 47.46 RSUs granted 0.1 $ 53.51 RSUs issued ( 0.1 ) $ 54.63 Outstanding at December 31, 2022 0.5 $ 46.93 As of December 31, 2022, there was total unrecognized compensation cost related to non-vested RSUs of $ 5.7 million, which is to be recognized over the remaining vesting period ranging from one year to three years . Restricted Stock Units — Performance Based As of December 31, 2022, a total of 423,738 shares of performance based restricted stock units were outstanding under the 2003 and 2013 incentive stock plans. The total amount of PRSUs that will ultimately vest is based on the achievement of various financial performance targets set forth by the Company’s Compensation Committee on the date of grant. PRSUs are based on a three-year performance period. The stock-based compensation expense related to awards granted to retirement-eligible employees is expensed on the grant date and is trued up as projections change. The fair value of the PRSU is based on the closing market price of the Company’s common stock on the date of grant and is amortized straight-line over the total three year period. A change in the performance measure expected to be achieved is recorded as an adjustment in the period in which the change occurs. The table presented below provides a summary, of the Company’s PRSU activity, at original grant amounts, for the years ended December 31,2022, 2021 and 2020: Weighted- Number of Average PRSUs Grant Date (In millions) Fair Value Outstanding at December 31, 2019 0.3 $ 60.48 PRSUs granted 0.1 $ 74.74 PRSUs issued ( 0.1 ) $ 50.50 PRSUs cancelled - $ - Outstanding at December 31, 2020 0.3 $ 68.77 PRSUs granted 0.2 $ 44.90 PRSUs issued - $ 50.50 PRSUs cancelled ( 0.1 ) $ 68.15 Outstanding at December 31, 2021 0.4 $ 57.19 PRSUs granted 0.1 $ 52.17 PRSUs issued - $ - PRSUs cancelled ( 0.1 ) $ 65.56 Outstanding at December 31, 2022 0.4 $ 53.71 As of December 31, 2022, there was total unrecognized compensation cost related to non-vested PRSUs of $ 2.3 million, which is to be recognized over the remaining vesting period ranging from one year to three years . The final amount of compensation cost to be recognized is dependent upon our financial performance. Stock-Based Compensation Cash Activity During 2022, 2021 and 2020 cash received from stock option exercises was $ 3.0 million, $ 7.7 million and $ 3.3 million, respectively. We used $ 2.1 million, $ 1.8 million and $ 7.7 million in cash related to the shares withheld to satisfy employee tax obligations for RSUs and PRSUs converted during the years ended December 31, 2022, 2021 and 2020, respectively. We classify the cash flows resulting from these tax benefits as financing cash flows. We either issue new shares of our common stock or utilize treasury shares upon the exercise of stock options or the conversion of stock units. Shares Authorized for Grant In 2019, an amendment to the Hexcel Corporation 2013 Incentive Stock Plan (the “Plan”) was adopted that increased the number of shares of the Company’s common stock authorized for issuance under the Plan by 3,300,000 shares. As of December 31, 2022, an aggregate of 3.0 million shares were authorized for future grant under our stock plan, which covers stock options, RSUs, PRSUs and at the discretion of Hexcel, could result in the issuance of other types of stock-based awards. Employee Stock Purchase Plan (“ESPP”) The Company offers an ESPP, which allowed for eligible employees to contribute up to 10 % of their base earnings, to a maximum of $ 25,000 in a calendar year, toward the quarterly purchase of our common stock at a purchase price equal to 85 % of the fair market value of the common stock. There were 74,664 , 28,620 and 35,000 ESPP shares purchased in 2022, 2021 and 2020, respectively. The ESPP was suspended in April 2020 in response to the COVID pandemic, but was subsequently reinstated commencing with the third quarter of 2021.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Note 15 — Derivative Financial Instruments Interest Rate Swap Agreements At both December 31, 2022 and 2021, we had no interest rate swap agreements outstanding. The Company had treasury lock agreements to protect against unfavorable movements in the benchmark treasury rate related to the issuance of our senior unsecured notes. These hedges were designated as cash flow hedges, thus any change in fair value was recorded as a component of other comprehensive income (loss). As part of the issuance of our senior notes, we net settled these derivatives for $ 10 million in cash and the deferred gains recorded in other comprehensive income (loss) will be released to interest expense over the life of the senior notes. The effect of these settled treasury locks reduces the effective interest rate on the senior notes by approximately 0.25 %. Cross Currency and Interest Rate Swap Agreements In November 2020 we entered into a cross currency and interest rate swap which is designated as a cash flow hedge of a € 270 million, 5 -year amortizing, intercompany loan between one of our European subsidiaries and the U.S. parent company. Changes in the spot exchange are recorded to the general ledger and offset the fair value re-measurement of the hedged item. The net difference in the interest rates coupons is recorded as a credit to interest expense. The derivative swaps € 270 million bearing interest at a fixed rate of 0.30 % for $ 319.9 million at a fixed rate interest of 1.115 %. The interest coupons settle semi-annually . The principal will amortize each year on November 15, as follows: for years 1 through 4, beginning November 15, 2021, € 50 million versus $ 59.2 million, and a final settlement on November 15, 2025 of € 70 million versus $ 82.9 million. The carrying value of the derivative at December 31, 2022 is a current asset of $ 6.2 million and a long-term asset of $ 10.1 million . Foreign Currency Forward Exchange Contracts A number of our European subsidiaries are exposed to the impact of exchange rate volatility between the U.S. dollar and the subsidiaries’ functional currencies, being either the Euro or the British pound sterling. We have entered into contracts to exchange U.S. dollars for Euros and British pound sterling through June 2025. The aggregate notional amount of these contracts was $ 503.3 million at December 31, 2022 and $ 316.4 million at December 31, 2021. The purpose of these contracts is to hedge a portion of the forecasted transactions of European subsidiaries under long-term sales contracts with certain customers. These contracts are expected to provide us with a more balanced matching of future cash receipts and expenditures by currency, thereby reducing our exposure to fluctuations in currency exchange rates. The effective portion of the hedges was losses of $ 27.9 million, losses of $ 13.3 million and gains of $ 10.9 million, for the years ended December 31, 2022, 2021 and 2020, respectively, and are recorded in other comprehensive (loss) income. At December 31, 2022, $ 5.3 million of the carrying amount of these contracts was classified in assets ($ 1.9 million of which was recorded in prepaid expenses and other current assets) and $ 19.4 million as liabilities ($ 5.3 million of which is in other non-current liabilities) on the Consolidated Balance Sheets and $ 1.9 million of the carrying amount of these contracts was classified in assets ($ 1.7 million of which was recorded in prepaid expenses and other current assets) and $ 6.8 million as liabilities ($ 3.9 million of which is in other non-current liabilities) at December 31, 2021. During the years ended December 31, 2022 and 2021 the net impact for the hedges recognized in sales was a loss of $ 18.7 million and a gain of $ 5.2 million, respectively. For the three years ended December 31, 2022, 2021 and 2020, hedge ineffectiveness was immaterial. In addition, we enter into foreign exchange forward contracts which are not designated as hedges. These are used to provide an offset to transactional gains or losses arising from the remeasurement of non-functional monetary assets and liabilities such as accounts receivable. The change in the fair value of the derivatives is recorded in the statement of operations. There are no credit contingency features in these derivatives. During the years ended December 31, 2022, 2021 and 2020, we recognized net foreign exchange gains of $ 3.3 million, $ 1.3 million, and $ 2.4 million, respectively, in the Consolidated Statements of Operations. The carrying amount of the contracts for asset and liability derivatives not designated as hedging instruments was $ 0.7 million of current liabilities on our Consolidated Balance Sheets at December 31, 2022. The activity, net of tax, in accumulated other comprehensive loss related to foreign currency forward exchange contracts for the years ended December 31, 2022, 2021 and 2020 was as follows: (In millions) 2022 2021 2020 Unrealized (loss) gain at beginning of period, net of tax $ ( 3.5 ) $ 10.6 $ ( 8.4 ) Loss (gain) reclassified to net sales 14.0 ( 4.0 ) 10.9 (Decrease) increase in fair value ( 21.0 ) ( 10.1 ) 8.1 Unrealized (loss) gain at end of period, net of taxes $ ( 10.5 ) $ ( 3.5 ) $ 10.6 Unrealized losses of $ 12.2 million recorded in accumulated other comprehensive loss, net of tax of $ 2.8 million, as of December 31, 2022 are expected to be reclassified into earnings over the next twelve months as the hedged sales are recorded. The impact of credit risk adjustments was immaterial for the three years. Commodity Swap Agreements We use commodity swap agreements to hedge against price fluctuations of raw materials, including propylene (the principal component of acrylonitrile). As of December 31, 2022, the Company had commodity swap agreements with a notional value of $ 26.8 mi llion. The swaps mature monthly through December 2024 . The swaps are accounted for as a cash flow hedge of our forward raw material purchases. To ensure the swaps are highly effective, all of the critical terms of the swap matched the terms of the hedged items. The fair value of the commodity swap agreements was an asset of $ 0.5 million and a liability of $ 8.6 million (of which $ 1.4 million was recorded in long term liabilities ) at December 31, 2022 and an asset of $ 0.9 million ($ 0.9 million of which was recorded in prepaid expenses and other current assets) and a liability of $ 2.3 million at December 31, 2021.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 16 — Commitments and Contingencies We are involved in litigation, investigations and claims arising out of the normal conduct of our business, including those relating to commercial transactions, environmental, employment and health and safety matters. While it is impossible to predict the ultimate resolution of litigation, investigations and claims asserted against us , we believe, based upon our examination of currently available information, our experience to date, and advice from legal counsel, that, after taking into account our existing insurance coverage and amounts already provided for, the currently pending legal proceedings against us will not have a material adverse impact on our consolidated results of operations, financial position or cash flows . Environmental Matters We have been named as a potentially responsible party (“PRP”) with respect to the below and other hazardous waste disposal sites that we do not own or possess, which are included on, or proposed to be included on, the Superfund National Priority List of the U.S. Environmental Protection Agency (“EPA”) or on equivalent lists of various state governments. Because the Federal Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA” or “Superfund”) allows for joint and several liability in certain circumstances, we could be responsible for all remediation costs at such sites, even if we are one of many PRPs. We believe, based on the amount and nature of the hazardous waste at issue, and the number of other financially viable PRPs at each site, that our liability in connection with such environmental matters will not be material . Lower Passaic River Study Area Hexcel together with approximately 48 other PRPs that comprise the Lower Passaic Cooperating Parties Group (the “CPG”) are subject to a May 2007 Administrative Order on Consent (“AOC”) with the EPA requiring the CPG to perform a Remedial Investigation/Feasibility Study of environmental conditions of a 17 -mile stretch of the Passaic River in New Jersey (the “Lower Passaic River”). We were included in the CPG based on our operations at our former manufacturing site in Lodi, New Jersey. In March 2016, the EPA issued a Record of Decision (“ROD”) setting forth the EPA’s selected remedy for the lower eight miles of the Lower Passaic River at an expected cost ranging from $ 0.97 billion to $ 2.07 billion. In August 2017, the EPA appointed an independent third-party allocation expert to make recommendations on the relative liability of approximately 120 identified non-government PRPs for the lower eight miles of the Lower Passaic River. In December 2020, the allocator issued its non-binding report on PRP liability (including Hexcel’s) to the EPA. In October 2021, the EPA released a ROD selecting an interim remedy for the upper nine miles of the Lower Passaic River at an expected additional cost ranging from $ 308.7 million to $ 661.5 million . In October 2016, pursuant to a settlement agreement with the EPA, Occidental Chemical Corporation (“OCC”), one of the PRPs, commenced performance of the remedial design required by the ROD for the lower eight miles of the Lower Passaic River, reserving its right of cost contribution from all other PRPs. In June 2018, OCC filed suit against approximately 120 parties, including Hexcel, in the U.S. District Court of the District of New Jersey seeking cost recovery and contribution under CERCLA related to the Lower Passaic River. In July 2019, the court granted in part and denied in part the defendants’ motion to dismiss. In August 2020, the court granted defendants’ motion for summary judgement for certain claims. Discovery for the remaining claims is ongoing. On February 24, 2021, Hexcel and certain other defendants filed a third-party complaint against the Passaic Valley Sewerage Commission and certain New Jersey municipalities seeking recovery of Passaic-related cleanup costs incurred by defendants, as well as contribution for any cleanup costs incurred by OCC for which the court deems the defendants liable . On December 16, 2022, the EPA lodged a Consent Decree with the U.S. District Court for the District of New Jersey requesting court approval of a $ 150 million settlement of the EPA’s CERCLA claims against Hexcel and 83 other PRPs for costs related to alleged contamination of the upper and lower portions of the Lower Passaic River. The 84 PRPs have collectively placed $ 150 million in escrow, pending District Court approval of the Consent Decree. The Consent Decree is subject to a public comment period and interested parties may have opportunities to provide additional evidence or make arguments in support or opposition to the Consent Decree. Hexcel is unable to estimate when or if the District Court will approve the Consent Decree. Environmental remediation reserve activity for the three years ended December 31, was as follows: (In millions) 2022 2021 2020 Beginning remediation accrual balance $ 2.1 $ 2.4 $ 2.5 Current period expenses — — — Cash expenditures ( 1.3 ) ( 0.3 ) ( 0.1 ) Ending remediation accrual balance $ 0.8 $ 2.1 $ 2.4 Summary of Environmental Reserves Our estimate of liability as a PRP and our remaining costs associated with our responsibility to remediate the Lower Passaic River and other sites are accrued in the Consolidated Balance Sheets. As of December 31, 2022 and December 31, 2021, our aggregate environmental related accruals were $ 0.8 million and $ 2.1 million, respectively. These amounts were included in non-current liabilities with the exception of $ 0.1 million at December 31, 2021 which was included in accrued liabilities. These accruals can change significantly from period to period due to such factors as additional information on the nature or extent of contamination, the methods of remediation required, changes in the apportionment of costs among responsible parties and other actions by governmental agencies or private parties, or the impact, if any, of being named in a new matter. Product Warranty Warranty expense for the years ended December 31, 2022, 2021 and 2020 and accrued warranty cost, included in “other accrued liabilities” in the Consolidated Balance Sheets were as follows: Product (In millions) Warranties Balance as of December 31, 2019 $ 5.5 Warranty expense 1.7 Deductions and other ( 4.6 ) Balance as of December 31, 2020 $ 2.6 Warranty expense 2.0 Deductions and other ( 2.1 ) Balance as of December 31, 2021 $ 2.5 Warranty expense 3.3 Deductions and other ( 2.7 ) Balance as of December 31, 2022 $ 3.1 Purchase Obligations At December 31, 2022, purchase commitments were $ 11.4 million for 2023, $ 11.7 million for 2024, $ 6.1 million for 2025, $ 2.5 million for 2026, $ 2.5 million for 2027, and $ 8.4 million thereafter.

Segment Reporting [Abstract]
Segment Information	Note 18 — Segment Information The financial results for our segments are prepared using a management approach, which is consistent with the basis and manner in which we internally segregate financial information for the purpose of assisting in making internal operating decisions. We evaluate the performance of our segments based on operating income, and generally account for intersegment sales based on arm’s length prices. We report two segments, Composite Materials and Engineered Products. Corporate and certain other expenses are not allocated to the segments, except to the extent that the expense can be directly attributable to the segment. Corporate & Other is shown to reconcile to Hexcel’s consolidated results. In addition to the product line-based segmentation of our business, we also monitor sales into our principal end markets as a means to understanding demand for our products. The following table presents financial information on our segments as of December 31, 2022, 2021 and 2020 and for the years then ended.

Fair Value Measurements

Fair Value Measurements	12 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 19— Fair Value Measurements The fair values of our financial instruments are classified into one of the following categories: • Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for identical assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs. • Level 2: Observable inputs other than quoted prices in active markets but corroborated by market data. • Level 3: Unobservable inputs are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs. In determining fair value, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as consider our own and counterparty credit risk. At December 31, 2022 and 2021, we had one liability which utilized Level 3 inputs. For derivative assets and liabilities that utilize Level 2 inputs, we prepare estimates of future cash flows of our derivatives, which are discounted to a net present value. The estimated cash flows and the discount factors used in the valuation model are based on observable inputs, and incorporate non-performance risk (the credit standing of the counterparty when the derivative is in a net asset position, and the credit standing of Hexcel when the derivative is in a net liability position). The fair value of these assets and liabilities was approximately $ 22.1 million and $ 28.6 million at December 31, 2022, and approximately $ 10.2 million and $ 9.3 million at December 31, 2021. In addition, the fair value of these derivative contracts, which are subject to a master netting arrangement under certain circumstances, is presented on a gross basis in the Consolidated Balance Sheet. Below is a summary of valuation techniques for all Level 2 financial assets and liabilities: • Cross Currency and Interest Rate Swap Agreements — valued using the USD Secured Overnight Financing Rate (“SOFR”) curves and quoted forward foreign exchange prices at the reporting date. The fair value of the assets was $ 16.3 million at December 31, 2022 and the fair value of the assets was $ 7.4 million at December 31, 2021. • Foreign exchange derivative assets and liabilities — valued using quoted forward foreign exchange prices at the reporting date. The fair value of assets and liabilities at December 31, 2022 was $ 5.3 million and $ 20.1 million, respectively. The fair value of assets and liabilities at December 31, 2021 was $ 1.9 million and $ 7.0 million, respectively. • Commodity swap agreements — valued using quoted forward commodity prices at the reporting date. The fair value of the assets and liabilities at December 31, 2022 was $ 0.5 million and $ 8.6 million, respectively. The fair value of the assets and liabilities at December 31, 2021 was $ 0.9 million and $ 2.3 million, respectively. Counterparties to the above contracts are highly rated financial institutions, none of which experienced any significant downgrades in 2021 that would reduce the receivable amount owed, if any, to the Company.

Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2022
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The accompanying consolidated financial statements include the accounts of Hexcel Corporation and its subsidiaries after elimination of all intercompany accounts, transactions, and profits. At December 31, 2022, we had a 50 % equity ownership investment in the joint venture described above which is accounted for using the equity method of accounting.
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements have been prepared by us pursuant to the rules and regulations of the U.S. Securities and Exchange Commission ("SEC") and are in conformity with U.S. generally accepted accounting principles ("GAAP"). Our fiscal year end is December 31. Unless otherwise stated, all years and dates refer to our fiscal year. In November 2020, we closed our wind energy prepreg production facility in Windsor, Colorado and as a result, certain plant assets to be sold have been recorded in “Assets held for sale” in the Consolidated Balance Sheets at both December 31, 2022 and 2021. During the year ended December 31, 2022, we reduced the carrying value of the Windsor facility by approximately $ 3 million which was recorded in "Other operating (income) expense" on the Consolidated Statements of Operations.
Use of Estimates	Use of Estimates Preparation of the accompanying consolidated financial statements and related disclosures 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, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash on hand and all highly liquid investments with an original maturity of three months or less when purchased. Our cash equivalents are held in prime money market investments with strong sponsor organizations which are monitored on a continuous basis.
Inventories	Inventories Inventories are stated at the lower of cost or net realizable value, with cost determined using the average cost methods. Inventory is reported at its estimated net realizable value based upon our historical experience with inventory becoming obsolete due to age, changes in technology and other factors. Inventory cost consists of materials, labor, and manufacturing related overhead associated with the purchase and production of inventories.
Property, Plant and Equipment	Property, Plant and Equipment Property, plant and equipment, including capitalized interest applicable to major project expenditures, is recorded at cost. Asset and accumulated depreciation accounts are eliminated for dispositions, with resulting gains or losses reflected in earnings. Depreciation of plant and equipment is provided generally using the straight-line method over the estimated useful lives of the various assets. The estimated useful lives range from 10 to 40 years for buildings and improvements and from 3 to 25 years for machinery and equipment. Repairs and maintenance are expensed as incurred, while major replacements and betterments are capitalized and depreciated over the remaining useful life of the related asset.
Leases	Leases The Company regularly enters into operating leases for certain buildings, equipment, parcels of land, and vehicles and accounts for such leases under the provisions of Accounting Standards Codification (“ASC”) 842, accounting for leases. Accordingly, we capitalize all agreements with terms for more than one year, where a right of use asset was identified. Generally, amounts capitalized represent the present value of minimum lease payments over the term, and the duration is equivalent to the base agreement, however, management uses certain assumptions when determining the value and duration of leases. These assumptions include, but are not limited to, the probability of renewing a lease term, certain future events impacting lease payments, as well as fair values not explicit in an agreement. Such assumptions impacted the duration of many of our building leases, as well as certain of our equipment leases. In addition, we elected certain expedients, such as the election to capitalize lease and non-lease components of an agreement as a single component for purposes of simplicity, with the exception of those related to equipment and machinery. In determining the lease renewal, management considers the need and ability to substitute a given asset, as well as certain conditions such as related contractual obligations to our customers (i.e., a contractual obligation of a customer requiring certain manufacturing proximities). In determining fair value, management considers the stand-alone value of an asset in an ordinary market as well as incurring certain costs to terminate an agreement. Most of our leases do not include variable payments but contain scheduled escalations. Any lease payments tied to certain future indexes are adjusted on a go forward basis as those indexes become known.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill represents the excess of the purchase price over the fair value of the identifiable net assets of an acquired business. Goodwill is tested for impairment at the reporting unit level annually, in the fourth quarter, or when events or changes in circumstances indicate that goodwill might be impaired. The Company performed a qualitative assessment (“Step Zero”) and determined that it was more likely than not that the fair values of our reporting units were not less than their carrying values and it was not necessary to perform a quantitative goodwill impairment test. We amortize the cost of other intangibles over their estimated useful lives unless such lives are deemed indefinite. We have indefinite lived intangible assets which are not amortized but are tested annually for impairment during the fourth quarter of each year, or when events or changes in circumstances indicate the potential for impairment. If the carrying amount of the indefinite lived intangible exceeds the fair value, it is written down to its fair value, which is calculated using a discounted cash flow model.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets The Company reviews long-lived assets, including property, plant and equipment and definite-lived intangible assets, for impairment whenever changes in circumstances or events may indicate that the carrying amounts are not recoverable. These indicators include, but are not limited to: a significant decrease in the market price of a long-lived asset, a significant change in the extent or manner in which a long-lived asset is used or its physical condition, a significant adverse change in legal factors or business climate that could affect the value of a long-lived asset, an accumulation of costs significantly in excess of the amount expected for the acquisition or construction of a long-lived asset, a current period operating or cash flow loss combined with a history of losses associated with a long-lived asset and a current expectation that, more likely than not, a long-lived asset will be sold or otherwise disposed of significantly before the end of its previously estimated life.
Software Development Costs	Software Development Costs Costs incurred to develop software for internal use are accounted for under ASC 350-40, “Internal-Use Software.” All costs relating to the preliminary project stage and the post-implementation/operation stage are expensed as incurred. Costs incurred during the application development stage are capitalized and amortized over the useful life of the software, which can range from three to ten years . The amortization of capitalized costs commences after the software has been tested and is placed into operations.
Debt Financing Costs	Debt Financing Costs Debt financing costs are deferred and amortized to interest expense over the life of the related debt. We capitalize financing fees related to our revolving credit facility and record them as a non-current asset in our Consolidated Balance Sheets. Financing fees related to our bonds and notes are capitalized and recorded as a non-current contra liability in our Consolidated Balance Sheets. See Note 6, Debt, for further information on debt financing costs.
Share-Based Compensation	Share-Based Compensation The fair value of Restricted Stock Units (“RSUs”) is equal to the market price of our stock at date of grant and is amortized to expense ratably over the vesting period. Performance restricted stock units (“PRSUs”) are a form of RSUs in which the number of shares ultimately received depends on the extent to which we achieve a specified performance target. The fair value of the PRSU is based on the closing market price of the Company’s common stock on the date of grant and is amortized straight-line over the total vesting period. A change in the performance measure expected to be achieved is recorded as an adjustment in the period in which the change occurs. We use the Black-Scholes model to calculate the fair value for all stock option grants, based on the inputs relevant on the date granted, such as the market value of our shares, prevailing risk-free interest rate, etc. The value of the portion of the award, after considering potential forfeitures, that is ultimately expected to vest is recognized as expense in our consolidated statements of operations on a straight-line basis over the requisite service periods. The value of RSUs, PRSUs and non-qualifying options awards for retirement eligible employees is expensed on the grant date as they are fully vested.
Currency Translation	Currency Translation The assets and liabilities of international subsidiaries are translated into U.S. dollars at year-end exchange rates, and revenues and expenses are translated at average exchange rates during the year. Cumulative currency translation adjustments are included in “accumulated other comprehensive loss” in the stockholders’ equity section of the Consolidated Balance Sheets.
Revenue Recognition	Revenue Recognition Revenue is predominately derived from a single performance obligation under long-term agreements with our customers and pricing is fixed and determinable. The majority of our revenue is recognized at a point in time when the customer has obtained control of the product. We have determined that individual purchase orders (“PO”), whose terms and conditions taken with a master agreement, create the revenue contracts which are generally short-term in nature. For those sales which are not tied to a long-term agreement, we generate a PO that is subject to our standard terms and conditions. Revenue is recognized over time for customer contracts that contain a termination for convenience clause (“T for C") and where the products produced do not have an alternative use. For revenue recognized over time, we estimate the amount of revenue earned at a given point during the production cycle based on certain costs factors such as raw materials and labor incurred to date, plus a reasonable profit, which is known as the cost-to-cost input method. Our revenue recognition policy recognizes the following practical expedients allowed under ASC 606: • Payment terms with our customers which are one year or less, are not considered a performance obligation. • Shipping and handling fees and costs incurred in connection with products sold are recorded in cost of sales in our Consolidated Statements of Operations and are not considered a performance obligation to our customers. Our performance obligations on our orders are generally satisfied within one year from a given reporting date therefore we omit disclosure of the transaction price allocated to remaining performance obligations on open orders.
Product Warranty	Product Warranty We provide for an estimated amount of product warranty at the point a claim is probable and estimable. This estimated amount is provided by product and based on current facts, circumstances, and historical warranty experience.
Research and Technology	Research and Technology Significant costs are incurred each year in connection with research and technology (“R&T”) programs that are expected to contribute to future earnings. Such costs are related to the development and, in certain instances, the qualification and certification of new and improved products and their uses. R&T costs are expensed as incurred.
Income Taxes	Income Taxes We provide for income taxes using the asset and liability approach . Under this approach, deferred income tax assets and liabilities reflect tax net operating loss and credit carryforwards and the tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting and income tax purposes. Deferred tax assets require a valuation allowance when it is not more likely than not, based on the evaluation of positive and negative evidence, that the deferred tax assets will be realized. The realization of deferred tax assets is dependent upon the timing and magnitude of future taxable income prior to the expiration of the deferred tax assets’ attributes. When events and circumstances so dictate, we evaluate the realizability of our deferred tax assets and the need for a valuation allowance by forecasting future taxable income. Investment tax credits are recorded on a flow-through basis, which reflects the credit in net income as a reduction of the provision for income taxes in the same period as the credit is realized for federal income tax purposes. In addition, we recognize interest accrued related to unrecognized tax benefits as a component of interest expense and penalties as a component of income tax expense in the Consolidated Statements of Operations.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially subject us to significant concentrations of credit risk consist primarily of trade accounts receivable. Two customers and their related subcontractors accounted for approximately 51 % of our annual net sales in 2022, 49 % in 2021 and 52 % in 2020. Refer to Note 18 for further information on significant customers. We perform ongoing credit evaluations of our customers’ financial condition but generally do not require collateral or other security to support customer receivables. We establish an allowance for doubtful accounts based on factors surrounding the credit risk of specific customers, historical trends, and other financial information.
Derivative Financial Instruments	Derivative Financial Instruments We use various financial instruments, including foreign currency forward exchange contracts, commodity, and interest rate agreements, to manage our exposure to market fluctuations by generating cash flows that offset, in relation to their amount and timing, the cash flows of certain foreign currency denominated transactions, commodities or underlying debt instruments. We mark our foreign exchange forward contracts to fair value. When the derivatives qualify, we designate our foreign currency forward exchange contracts as cash flow hedges against forecasted foreign currency denominated transactions and report the changes in fair value of the instruments in “accumulated other comprehensive loss” until the underlying hedged transactions affect income. We designate our interest rate agreements as fair value or cash flow hedges against specific debt instruments and recognize interest differentials as adjustments to interest expense as the differentials may occur; the fair value of the interest rate swaps is recorded in other assets or other non-current liabilities with a corresponding amount to “accumulated other comprehensive loss”. We do not use financial instruments for trading or speculative purposes. In accordance with accounting guidance, we recognize all derivatives as either assets or liabilities on our Consolidated Balance Sheets and measure those instruments at fair value.
Self-insurance	Self-insurance We are self-insured up to specific levels for certain medical and health insurance and workers’ compensation plans. Accruals are established based on actuarial assumptions and historical claim experience and include estimated amounts for incurred but not reported claims.
Recently Enacted Government Legislation	Recently Enacted Government Legislation On August 16, 2022, the U.S. enacted the Inflation Reduction Act (the "IRA") of 2022. The IRA contains a number of tax provisions including a new corporate alternative minimum tax, an excise tax on stock buybacks, and incentives for energy and climate initiatives. These provisions are effective for taxable years beginning after December 31, 2022. Currently, we do not qualify for the corporate alternative minimum tax. The impact of the excise tax will be dependent on the extent of share repurchases made in future periods. We are assessing the applicability and impact to Hexcel of incentives for energy and climate initiatives.
