Organization, Consolidation and Presentation of Financial Statements [Abstract]
Background and Basis of Presentation	1. BACKGROUND AND BASIS OF PRESENTATION Triumph Group, Inc. ("Triumph" or the "Company") is a Delaware corporation which, through its operating subsidiaries, designs, engineers, manufactures and sells products for the global aerospace original equipment manufacturers (" OEMs") of aircraft and aircraft components and repairs and overhauls aircraft components and accessories for commercial airline, air cargo carrier and military customers on a worldwide basis. Triumph and its subsidiaries (collectively, the "Company") are organized based on the products and services that they provide. The Company has two reportable segments: Systems & Support and Interiors. Systems & Support consists of the Company’s operations that provide integrated solutions, including design; development; and support of proprietary components, subsystems and systems, as well as production of complex assemblies using external designs. Capabilities include hydraulic, mechanical and electromechanical actuation, power and control; a complete suite of aerospace gearbox solutions, including engine accessory gearboxes and helicopter transmissions; active and passive heat exchange technology; fuel pumps, fuel metering units, and Full Authority Digital Electronic Control fuel systems; and hydromechanical and electromechanical primary and secondary flight controls. As disclosed in Note 3, in December 2023 the Company entered into a definitive agreement with AAR Corp. (“AAR”), to sell Systems & Support's maintenance, repair, and overhaul operations located in Wellington, Kansas; Grand Prairie, Texas; San Antonio, Texas; Hot Springs, Arkansas; and Chonburi, Thailand (“Product Support”). As a result of this agreement, the Company has classified the Product Support results of operations for all periods presented as discontinued operations, and has classified the assets and liabilities of the disposal group as held for sale as of March 31, 2023, and these operations are no longer reported as part of the Systems & Support reportable segment. Interiors consists of the Company’s operations that have historically supplied commercial, business, and regional manufacturers with large metallic structures and continues to supply aircraft interior systems, including air ducting and thermal acoustic insulations systems. Subsequent to the divestitures disclosed in Note 3, the remaining operations of Interiors are those that supply commercial and regional manufacturers with aircraft interior systems. The accompanying consolidated financial statements include the accounts of Triumph and its wholly-owned subsidiaries. Intercompany accounts and transactions have been eliminated from the consolidated financial statements. The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Cash and Cash Equivalents Cash equivalents consist of highly liquid investments with a maturity of three months or less at the time of purchase. Fair value of cash equivalents approximates carrying value. Trade and Other Receivables, net Trade and other receivables are recorded net of an allowance for expected credit losses. Trade and other receivables include amounts billed and currently due from customers. The Company performs ongoing credit evaluations of its customers and generally does not require collateral. The Company pools receivables that share underlying risk characteristics and records the allowance for expected credit losses based on a combination of prior experience, current economic conditions and management’s expectations of future economic conditions, and specific collectibility matters when they arise. The Company writes off balances against the allowance for expected credit losses when collectibility is deemed remote. The Company's trade and other receivables are exposed to credit risk; however, the risk is limited due to the diversity of the customer base. For the years ended March 31, 2024, 2023, and 2022, credit loss expense and write-offs were immaterial. Trade and other receivables, net composed of the following: March 31, 2024 2023 Total trade receivables $ 139,012 $ 119,583 Other receivables 4,033 42,010 Total trade and other receivables 143,045 161,593 Less: Allowance for credit losses ( 4,773 ) ( 5,477 ) Total trade and other receivables, net $ 138,272 $ 156,116 Goodwill and Intangible Assets The Company accounts for goodwill and intangible assets in accordance with ASC 350, Intangibles—Goodwill and Other . Under ASC 350, goodwill and intangible assets with indefinite lives are not amortized; rather, they are tested for impairment on at least an annual basis. Intangible assets with finite lives are amortized over their useful lives. The Company assesses whether goodwill impairment exists using both the qualitative and quantitative assessments. The qualitative assessment involves determining whether events or circumstances exist that indicate it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill. If based on this qualitative assessment the Company determines it is more likely than not that the fair value of a reporting unit is less than its carrying amount or if the Company elects not to perform a qualitative assessment, a quantitative assessment is performed as required by ASC 350 to determine whether a goodwill impairment exists at the reporting unit. The quantitative test is used to compare the carrying amount of the reporting unit's assets to the fair value of the reporting unit. If the fair value exceeds the carrying value, no further evaluation is required, and no impairment loss is recognized. If the carrying amount exceeds the fair value, then an impairment loss occurs. The impairment is measured by using the amount by which the carrying value exceeds the fair value not to exceed the amount of recorded goodwill. The determination of the fair value of its reporting units is based, among other things, on estimates of future operating performance of the reporting unit being valued. The Company is required to complete an impairment test for goodwill and record any resulting impairment losses at least annually. Changes in market conditions, among other factors, may have an impact on these estimates and require interim impairment assessments. When performing the quantitative impairment test, the Company's methodology includes the use of an income approach which discounts future net cash flows to their present value at a rate that reflects the Company's cost of capital, otherwise known as the discounted cash flow method ("DCF"). These estimated fair values are based on estimates of future cash flows of the businesses. Factors affecting these future cash flows include the continued market acceptance of the products and services offered by the businesses, the development of new products and services by the businesses and the underlying cost of development, the future cost structure of the businesses and future technological changes. The Company also incorporates market multiples for comparable companies in determining the fair value of its reporting units. Any such impairment would be recognized in full in the reporting period in which it has been identified. The fair value estimates resulting from the application of these methodologies are based on inputs classified within Level 3 of the fair value hierarchy, as described below. During the fourth quarter of the fiscal years ended March 31, 2024 and 2023, the Company performed its annual goodwill impairment assessment for each of its reporting units with no impairment identified. Finite-lived intangible assets are amortized over their useful lives ranging from 10 to 30 years . The Company continually evaluates whether events or circumstances have occurred that would indicate that the remaining estimated useful lives of long-lived assets, including intangible assets, may warrant revision or that the remaining balance may not be recoverable. Long-lived assets are evaluated for indicators of impairment. When factors indicate that long-lived assets, including intangible assets, should be evaluated for possible impairment, an estimate of the related undiscounted cash flows over the remaining life of the long-lived assets, including intangible assets, is used to measure recoverability based on the primary asset of the asset group. Some of the more important factors management considers include the Company's financial performance relative to expected and historical performance, significant changes in the way the Company manages its operations, negative events that have occurred, and negative industry and economic trends. If the estimated undiscounted cash flows are less than the carrying amount, measurement of the impairment will be based on the difference between the carrying value and fair value of the asset group, generally determined based on the present value of expected future cash flows associated with the use of the asset. See below for the Company's accounting policy regarding fair value measurements and the definition of fair value levels. Revenue Recognition and Contract Balances The Company's revenue is principally from contracts with customers to provide design, development, manufacturing, and support services associated with specific customer programs. The Company regularly enters into long-term master supply agreements that establish general terms and conditions and may define specific program requirements. Many agreements include clauses that provide sole supplier status to the Company for the duration of the program’s life. Purchase orders (or authorizations to proceed) are issued pursuant to the master supply agreements. Additionally, a majority of the Company’s agreements with customers include options for future purchases. Such options primarily reduce the administrative effort of issuing subsequent purchase orders and generally do not represent material rights granted to customers. The Company generally enters into agreements directly with its customers and is the principal in substantially all current contracts. The identification of a contract with a customer for purposes of accounting and financial reporting requires an evaluation of the terms and conditions of agreements to determine whether presently enforceable rights and obligations exist. Management considers a number of factors when making this evaluation that include, but are not limited to, the nature and substance of the business exchange, the specific contractual terms and conditions, the promised products and services, the termination provisions in the contract, as well as the nature and execution of the customer’s ordering process and how the Company is authorized to perform work. Generally, presently enforceable rights and obligations are not created until a purchase order is issued by a customer for a specified number of units of product or services. Therefore, the issuance of a purchase order is generally the point at which a contract is identified for accounting and financial reporting purposes. Management identifies the promises to the customer. Promises are generally explicitly stated in each contract, but management also evaluates whether any promises are implied based on the terms of the agreement, past business practice, or other facts and circumstances. Each promise is evaluated to determine if it is a performance obligation. A performance obligation is a promise in a contract to transfer a distinct good or service. The Company considers a number of factors when determining whether a promise is a distinct performance obligation, including whether the customer can benefit from the good or service on its own or together with other resources that are readily available to the customer, whether the Company provides a significant service of integrating goods or services to deliver a combined output to the customer, or whether the goods or services are highly interdependent. The Company’s performance obligations consist of a wide range of engineering design services and manufactured components, as well as spare parts and repairs for OEMs. The transaction price for a contract reflects the consideration the Company expects to receive for fully satisfying the performance obligations in the contract. Typically, the transaction price consists solely of fixed consideration but may include variable consideration for contractual provisions such as unpriced contract modifications, cost-sharing provisions, and other receipts or payments to customers. The Company identifies and estimates variable consideration, typically at the most likely amount the Company expects to receive from its customers. Variable consideration is only included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized for the contract will not occur, or when the uncertainty associated with the variable consideration is resolved. Consideration paid or payable to a customer is reflected as a reduction in net revenues when the amounts paid are not related to a distinct good or service at the later of when the related revenue is recognized or when the Company pays or promises to pay the consideration to the customer. The Company's contracts with customers generally require payment under normal commercial terms after delivery with payment typically required within 30 to 120 days of delivery. The Company generally is not subject to collecting sales tax and has made an accounting policy election to exclude from the transaction price any sales and other similar taxes collected from customers. As a result, any such collections are accounted for on a net basis. The total transaction price is allocated to each of the identified performance obligations using the relative stand-alone selling price. The objective of the allocation is to reflect the consideration that the Company expects to receive in exchange for the products or services associated with each performance obligation. Stand-alone selling price is the price at which the Company would sell a promised good or service separately to a customer. Stand-alone selling prices are established at contract inception, and subsequent changes in transaction price are allocated on the same basis as at contract inception. When stand-alone selling prices for the Company’s products and services are not observable, the Company uses either the “Expected Cost Plus a Margin” or "Adjusted Market Assessment" approaches to estimate stand-alone selling price. Expected costs are typically derived from the available periodic forecast information. Revenue is recognized when or as control of promised products or services transfers to a customer and is recognized at the amount allocated to each performance obligation associated with the transferred products or services. Service sales, principally representing repair, maintenance, and engineering activities are recognized over the contractual period or as services are rendered. Sales under long-term contracts with performance obligations satisfied over time are recognized using either an input or output method. The Company recognizes revenue over time as it performs on these contracts because of the continuous transfer of control to the customer as represented by contractual terms that entitle the Company to the reimbursement of costs plus a reasonable profit for work performed to manufacture products for which the Company has no alternate use or for work performed on a customer-owned asset. With control transferring over time, revenue is recognized based on the extent of progress toward completion of the performance obligation. The Company generally uses the cost-to-cost input method of progress for its contracts because it best depicts the transfer of control to the customer that occurs as work progresses. Under the cost-to-cost method, the extent of progress toward completion is measured based on the proportion of costs incurred to date to the total estimated costs at completion of the performance obligation. The Company reviews its cost estimates on contracts on a periodic basis, or when circumstances change and warrant a modification to a previous estimate. Cost estimates are largely based on negotiated or estimated purchase contract terms, historical performance trends and other economic projections. Significant factors that influence these estimates include inflationary trends, technical and schedule risk, internal and subcontractor performance trends, business volume assumptions, and asset utilization. Revenue and cost estimates are regularly monitored and revised based on changes in circumstances. Impacts from changes in estimates of net sales and cost of sales are recognized on a cumulative catch-up basis, which recognizes in the current period the cumulative effect of the changes on current and prior periods based on a performance obligation’s percentage of completion. Forward loss reserves for anticipated losses on long-term contracts are recorded in full when such losses become evident, to the extent required and are included in contract liabilities on the accompanying consolidated balance sheets. The Company believes that the accounting estimates and assumptions made by management are appropriate, however actual results could differ materially from those estimates. For the fiscal year ended March 31, 2024, cumulative catch-up adjustments resulting from changes in estimated contract values and contract costs during the fiscal year were immaterial. For the fiscal year ended March 31, 2023, cumulative catch-up adjustments resulting from changes in estimates increased revenue, operating income, income from continuing operations before income taxes, net income, and diluted earnings per share - continuing operations by approximately $ 21,208 , $ 27,963 , $ 27,963 , $ 27,963 , and $ 0.39 , respectively. The cumulative catch-up adjustments to operating income for the fiscal year ended March 31, 2023, included gross favorable adjustments of approximately $ 32,699 and gross unfavorable adjustments of approximately $ 4,736 . For the fiscal year ended March 31, 2022, cumulative catch-up adjustments resulting from changes in estimates increased revenue and operating income and decreased loss from continuing operations before income taxes, net loss and diluted loss per share - continuing operations by approximately $ 6,884 , $ 16,042 , $ 16,042 , $ 16,042 , and $ 0.25 , respectively. The cumulative catch-up adjustments to operating income for the fiscal year ended March 31, 2022, included gross favorable adjustments of approximately $ 30,560 and gross unfavorable adjustments of approximately $ 14,518 . Revenues for performance obligations that are not recognized over time are recognized at the point in time when control transfers to the customer. For performance obligations that are satisfied at a point in time, the Company evaluates the point in time when the customer can direct the use of and obtain the benefits from the products and services. Generally, the shipping terms determine the point in time when control transfers to customers. Shipping and handling activities are not considered performance obligations and related costs are included in cost of sales as incurred. Differences in the timing of revenue recognition and contractual billing and payment terms result in the recognition of contract assets and liabilities. Refer to Note 4 for further discussion. Warrants On December 1, 2022, the Company’s board of directors declared a distribution to holders of the Company’s shares of common stock in the form of warrants to purchase shares of common stock (the “Warrants”). Holders of common stock received three Warrants for every ten shares of common stock held as of December 12, 2022 (the "Record Date"). The Company issued approximately 19.5 million Warrants on December 19, 2022, to holders of record of common stock as of the close of business on the Record Date. Each Warrant represented the right to purchase initially one share of common stock, at an exercise price of $ 12.35 per Warrant, subject to certain anti-dilution adjustments. Payment for shares of common stock on exercise of Warrants could have been made in (i) cash or (ii) under certain circumstances, certain of the Company's outstanding notes (the "Designated Notes"). The common stock warrants were accounted for as derivative liabilities in accordance with ASC 815-40 and included within accrued liabilities on the accompanying consolidated balance sheets. The Company measured the Warrants at fair value as of the issuance date using a Monte Carlo pricing model, a Level 3 fair value measurement (as described below), due to the level of market activity. Inherent in the option pricing simulation are assumptions related to expected stock-price volatility, expected life and risk-free interest rate. The Company estimated the volatility of the Warrants based on implied and historical volatility of the Company’s common stock. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected remaining life of the Warrants. The expected life of the Warrants was based on the Company’s ability to redeem the Warrants, subject to a 20 calendar-day notice period, as well as the automatic acceleration of the Expiration Date following the Price Condition Date. During the three months ended December 31, 2022, due to increased trading volume, the Company began remeasuring outstanding Warrants using the Warrants trading price, a Level 1 fair value measurement (as described below). The Warrants were remeasured at each balance sheet date. Warrants remeasurement adjustments were recognized in warrant remeasurement gain, net on the accompanying consolidated statements of operations. At distribution, the fair value of the Warrants was $ 19,500 . Approximately 7.7 million Warrants were exercised in the year ended March 31, 2024, resulting in total cash proceeds, net of transaction costs, of approximately $ 79,961 , and $ 8,532 of warrants remeasurement gain was recognized in the year ended March 31, 2024. On July 6, 2023, the Company redeemed all of the approximately 11.4 million remaining outstanding Warrants for a total redemption price of approximately $ 11 pursuant to its June 16, 2023, notice of redemption. Leases The Company leases office space, manufacturing facilities, land, vehicles, and equipment. The Company determines if an agreement is or contains a lease at the lease inception date and recognizes right-of-use assets (“ROU”) and lease liabilities at the lease commencement date. A ROU asset and corresponding lease liability are not recorded for leases with an initial term of 12 months or less (“short-term leases”). ROU assets represent the Company's right to use an underlying asset during the lease term, and lease liabilities represent the Company's obligation to make lease payments arising from the lease. The determination of the length of lease terms is affected by options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. The existence of significant economic incentive is the primary consideration when assessing whether the Company is reasonably certain of exercising an option in a lease. Both finance and operating lease ROU assets and liabilities are recognized at commencement date and measured as the present value of lease payments to be made over the lease term. As the interest rate implicit in the lease is not readily available for most of the Company's leases, the Company uses its estimated incremental borrowing rate in determining the present value of lease payments. The estimated incremental borrowing rate is derived from information available at the lease commencement date. The lease ROU asset recognized at commencement is adjusted for any lease payments related to initial direct costs, prepayments, and lease incentives. For operating leases, lease expense is recognized on a straight-line basis over the lease term. For finance leases, lease expense comprises the amortization of the ROU assets recognized on a straight-line basis generally over the shorter of the lease term or the estimated useful life of the underlying asset and interest on the lease liability. Variable lease payments not dependent on a rate or index are recognized when the event, activity, or circumstance in the lease agreement upon which those payments are contingent is probable of occurring and are presented in the same line of the consolidated balance sheet as the rent expense arising from fixed payments. The Company has lease agreements with lease and non-lease components. Non-lease components are combined with the related lease components and accounted for as lease components for all classes of underlying assets. Retirement Benefits Defined benefit pension plans are recognized in the consolidated financial statements on an actuarial basis. A significant element in determining the Company's pension expense (income) is the expected long-term rate of return on plan assets. This expected return is an assumption as to the average rate of earnings expected on the funds invested or to be invested to provide for the benefits included in the projected pension benefit obligation. The Company applies this assumed long-term rate of return to a calculated value of plan assets, which recognizes changes in the fair value of plan assets in a systematic manner over five years. This produces the expected return on plan assets that is included in pension expense (income) . The difference between this expected return and the actual return on plan assets is deferred. The net deferral of past asset gains (losses) affects the calculated value of plan assets and, ultimately, future pension expense (income). The Company periodically experiences events or makes changes to its benefit plans that result in curtailment or special charges. Curtailments are recognized when events occur that significantly reduce the expected years of future service of present employees or eliminates the benefits for a significant number of employees for some or all of their future service. Curtailment losses are recognized when it is probable the curtailment will occur and the effects are reasonably estimable. Curtailment gains are recognized when the related employees are terminated or a plan amendment is adopted, whichever is applicable. From time to time, the Company may enter into transactions that relieve it of primary responsibility for all or more than a minor portion of certain of its pension benefit obligations. When these transactions are effected through an irrevocable action that relieves the Company of primary responsibility for its pension or other postretirement benefit obligations and eliminates significant risks related to the obligation and the related assets used to effect the transaction, they are considered settlements, as defined by ASC 715, Compensation – Retirement Benefits. When a transaction meets the definition of a settlement, at the time of settlement the Company recognizes as a gain or loss the pro rata amount of the net gain or loss in accumulated other comprehensive loss based on the proportion of the projected benefit obligation settled to the total projected benefit obligation. As required under ASC 715, the Company remeasures plan assets and obligations during an interim period whenever a significant event occurs that results in a material change in the net periodic pension cost. The determination of significance is based on judgment and consideration of events and circumstances impacting the pension costs. At March 31 of each year, the Company determines the fair value of its pension plan assets as well as the discount rate to be used to calculate the present value of plan liabilities. The discount rate is an estimate of the interest rate at which the pension benefits could be effectively settled. In estimating the discount rate, the Company looks to rates of return on high-quality, fixed-income investments currently available and expected to be available during the period to maturity of the pension benefits. The Company uses a portfolio of fixed-income securities, which receive at least the second-highest rating given by a recognized ratings agency. Contingencies Contingencies are existing conditions, situations or circumstances involving uncertainty as to possible gain or loss that will ultimately be resolved when future events occur or fail to occur. Such contingencies include, but are not limited to environmental obligations, litigation, regulatory investigations and proceedings, product quality, and gains or losses resulting from other events and developments. Liabilities for loss contingencies are accrued in the amount of the Company's best estimate for the ultimate loss when a loss is considered probable of having been incurred and is reasonably estimable. When there appears to be a range of possible costs with equal likelihood, liabilities are based on the low-end of such range. Disclosure is provided for material loss contingencies when a loss is probable but a reasonable estimate cannot be made, and when it is reasonably possible that a loss will be incurred or the amount of a loss will exceed the recorded provision. The Company regularly reviews contingencies to determine whether the likelihood of loss has changed and to assess whether a reasonable estimate of the loss or range of loss can be made. Contingencies that might result in gains are generally not accrued until the contingencies are resolved and the gain is realized or realizable. Refer to Note 17 for further disclosure. Fair Value Measurements Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. When determining fair value measurements for assets and liabilities required to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and also considers assumptions that market participants would use when pricing an asset or liability. The fair value hierarchy has three levels of inputs that may be used to measure fair value: Level 1—Unadjusted quoted prices in active markets for identical assets or liabilities; Level 2—Unadjusted quoted prices in active markets for similar assets or liabilities, or unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability; and Level 3—Unobservable inputs for the asset or liability. The Company has applied fair value measurements when measuring the warrants (refer to the above disclosure), when disclosing the fair value of its long-term debt not recorded at fair value (see Note 10) and when measuring its pension and postretirement plan assets (see Note 15). Income Taxes The Company accounts for income taxes using the asset and liability method. The asset and liability method requires recognition of deferred tax assets and liabilities for expected future tax consequences of temporary differences that currently exist between tax bases and financial reporting bases of the Company's assets and liabilities. A valuation allowance is provided on deferred taxes if it is determined that it is more likely than not that the asset will not be realized. Management judgment is required to determine the amount of benefit to be recognized in relation to an uncertain tax position. The Company uses a two-step process to evaluate tax positions. The first step requires an entity to determine whether it is more likely than not (greater than 50% chance) that the tax position will be sustained. The second step requires an entity to recognize in the financial statements the benefit of a tax position that meets the more-likely-than-not recognition criterion. The amounts ultimately paid upon resolution of issues raised by taxing authorities may differ materially from the amounts accrued and may materially impact the financial statements of the Company in future periods. The Company recognizes penalties and interest accrued related to income tax liabilities in the provision for income taxes on its consolidated statements of operations. Warranty Reserves A reserve has been established to provide for the estimated future cost of assurance-type warranties on our delivered products. The Company periodically reviews the reserves and adjustments are made accordingly. A provision for warranty on products delivered is made on the basis of historical experience and identified warranty issues. Warranties cover such factors as non-conformance to specifications and defects in material and workmanship. The majority of the Company's agreements include a three-year warranty, although certain programs have warranties up to 20 years . Warranty provisions and expenditures were immaterial for the years ended March 31, 2024, 2023, and 2022. Warranty reserves are included in accrued expenses and other noncurrent liabilities on the consolidated balance sheets. Refer to Note 8 and Note 11 for warranty reserve balances as of March 31, 2024 and 2023. Supplemental Cash Flow Information In November 2021, the Company entered into an agreement with the DOT under the AMJP for a grant of up to $ 21,259 . The receipt of the full award was primarily conditioned upon the Company committing to not furlough or lay off a defined group of employees during the six-month period of performance between November 2021 and May 2022. The Company received approximately $ 19,400 under the agreement, of which approximately $ 10,630 was received in the year ended March 31, 2022, and the remainder of which was received in the year ended March 31, 2023. In July 2022, the Company received a letter from the DOT confirming that the Company had satisfied the reporting requirements under the AMJP. In the years ended March 31, 2023 and 2022, the Company recognized as a reduction in cost of sales approximately $ 4,700 and $ 12,400 , respectively. The balance of the proceeds of approximately $ 2,300 related to discontinued operations, increasing income from discontinued operations by approximately $ 600 , and $ 1,700 in the years ended March 31, 2023 and 2022, respectively. For the fiscal years ended March 31, 2024, 2023, and 2022, the Company paid $ 11,771 , $ 4,565 , and $ 5,382 , respectively, for income taxes, net of income tax refunds received.

Discontinued Operations and Disposal Groups [Abstract]
Divested Operations and Assets Held For Sale	3. DIVESTED OPERATIONS AND ASSETS HELD FOR SALE Fiscal 2024 Divestiture and Discontinued Operations In December 2023, the Company’s Board of Directors committed to a plan, and the Company entered into a definitive agreement with AAR, to sell Product Support for cash proceeds of $ 725,000 subject to adjustments related to the closing balance sheet and certain transaction expenses. This transaction closed on March 1, 2024, and the Company recognized a gain of approximately $ 548,250 , net of transaction costs and certain other purchase price adjustments. The gain is included within discontinued operations on the accompanying consolidated statement of operations. Product Support companies provide aftermarket maintenance, repair, and overhaul solutions for commercial, regional and military aircraft. As a result of this transaction, effective in the third quarter of fiscal 2024, we classified our results of operations for all periods presented to reflect Product Support as discontinued operations and classified the assets and liabilities of this disposal group as held for sale on the accompanying consolidated balance sheet as of March 31, 2023. Under the terms of the purchase agreement, we will continue to guarantee the performance of certain of the divested legal entities pursuant to pre-existing performance guarantee agreements covering existing contracts with specific customers that are expected to be fully satisfied within the next twelve months. There is no limitation to the maximum potential future liabilities under these guarantee agreements; however, we are fully indemnified by the buyer, AAR, against such losses that may arise from their failure to perform under the related contracts. The Company has also indemnified the buyer for a period of three years from the date of the transaction on product liability or warranty claims related to Product Support products and operations prior to the transaction date to the extent exceeding an aggregate amount of $ 1,000 . Other than these guarantees, a short-term transition services agreement, commercial purchases and sales which are not significant and are entered into in the ordinary course of business, and other customary short-term transitional activities, the Company will have no further continuing involvement with Product Support. The following table shows the results of Product Support within discontinued operations for each of the periods presented: Year ended March 31, 2024 2023 2022 Major line items constituting pretax income of discontinued operations Net sales $ 240,954 $ 248,566 $ 197,238 Operating costs and expenses: Cost of sales (exclusive of depreciation shown separately below) 184,304 181,717 144,426 Selling, general and administrative 20,246 19,343 17,815 Depreciation and amortization 3,625 3,322 4,126 Restructuring — 1,777 74 Gain on sale of discontinued operations, net of transaction costs ( 548,250 ) — — ( 340,075 ) 206,159 166,441 Operating income 581,029 42,407 30,797 Interest expense and other, net 22,390 22,503 22,781 Income from discontinued operations before income taxes 558,639 19,904 8,016 Income tax expense 11,788 2,728 397 Income from discontinued operations $ 546,851 $ 17,176 $ 7,619 The Company's accounting policy to allocate to discontinued operations other consolidated interest that is not directly attributable to or related to other operations of the entity based on the ratio of net assets to be sold or discontinued less debt that is required to be paid as a result of the disposal transaction to the sum of total net assets of the consolidated group plus consolidated debt, adjusted for debt that will be assumed by the buyer; debt that is required to be paid as a result of the disposal transaction; and debt that can be directly attributed to other operations of the entity. In applying the above policy, the Company allocated interest expense to discontinued operations of approximately $ 21,857 , $ 21,619 , and $ 22,646 in the years ended March 31, 2024, 2023, and 2022, respectively. March 31, 2023 ASSETS Carrying amount of major classes of assets included as part of discontinued operations: Trade and other receivables, less allowance for credit losses 2,905 $ 40,659 Contract assets 16,287 Inventory, net 80,161 Prepaid expenses and other current assets 2,989 Property and equipment, net 28,178 Other, net 2,488 Total assets of the disposal group classified as held-for-sale in the statement of financial position $ 170,762 LIABILITIES Carrying amount of major classes of liabilities included as part of discontinued operations: Accounts payable $ 24,357 Contract liabilities 387 Accrued expenses 9,669 Other noncurrent liabilities 65 Total liabilities of the disposal group classified as held-for-sale in the statement of financial position $ 34,478 The accompanying consolidated statements of cash flows do not present cash flows from discontinued operations separately from cash flows from continuing operations. Capital expenditures and other operating and investing noncash items of the discontinued operations for the years ended March 31, 2024, 2023, and 2022, were immaterial. Fiscal 2023 Divestitures In January 2022, the Company’s Board of Directors committed to a plan to sell its manufacturing operations located in Stuart, Florida. In February 2022, the Company entered into a definitive agreement with the buyer of these manufacturing operations. This transaction closed in July 2022. The Company recognized a gain of approximately $ 96,800 , net of transaction costs in fiscal year 2023, which is presented on the accompanying consolidated statements of operations within loss (gain) on sale of assets and businesses for the year ended March 31, 2023 . In the year ended March 31, 2024, the Company paid $ 6,800 to the buyer of the Stuart manufacturing operations and recognized a loss of approximately $ 3,900 due to the resolution of claims by the buyer related to the accounts payable representation and warranty under the purchase agreement and the finalization of certain purchase price adjustments related to the transferred working capital of the divested operations. Additionally, in the year ended March 31, 2024, the Company recognized a loss on sale of approximately $ 8,300 related to an adjustment that would have reduced the fiscal 2023 gain on sale. Other claims for indemnification with the Buyer of the Stuart facility (refer to Note 17) remain outstanding. The operating results of the Stuart, Florida, manufacturing operations are included within the Interiors reportable segment through the date of divestiture. Fiscal 2022 Divestitures In May 2020, the Company’s Board of Directors committed to a plan to sell its composites manufacturing operations located in Milledgeville, Georgia and Rayong, Thailand. In August 2020, the Company entered into a definitive agreement with the buyer of the composites manufacturing operations in Georgia and Thailand. In February 2021, the Company entered into a definitive agreement to sell its large structure manufacturing operations in Red Oak, Texas, to the same buyer of the Milledgeville and Rayong composites manufacturing operations. These transactions closed in May 2021. Upon the completion of the sale of the composites and large structure manufacturing operations, the Company received proceeds of approximately $ 155,000 net of the purchase of a facility related to the divestiture and other transaction costs and recognized a loss of approximat ely $ 6,000 , which is presented on the accompanying consolidated statements of operations within loss (gain) on sale of assets and businesses for the year ended March 31, 2022. The operating results of these related operations are included within the Interiors segment through the date of divestiture. As disclosed in Note 15, as a result of the completed sale of these manufacturing operations, the Company recognized a curtailment loss of approximately $ 16,000 during the year ended March 31, 2022. In August 2021, the Company’s Board of Directors committed to a plan to sell and license certain legacy product lines of the Company’s Staverton, United Kingdom operations. The transaction included the existing facility and select product lines associated with the site. The transaction closed in October 2021 for net proceeds of approximately $ 34,000 , and the effect on earnings was insignificant. The operating results of the Staverton, United Kingdom, manufacturing operations were included within the Systems & Support reportable segment through the date of divestiture. As a result of the fiscal 2022 divestitures described above, including routine closing working capital adjustments, the Company recognized total losses of approximately $ 9,300 in the year ended March 31, 2022.

Revenue Recognition and Contracts with Customers	4. REVENUE RECOGNITION AND CONTRACTS WITH CUSTOMERS Disaggregation of Revenue The Company disaggregates revenue based on the method of measuring satisfaction of the performance obligation either over time or at a point in time.

This typically occurs when revenue is recognized over time but the Company's contractual right to bill the customer and receive payment is conditional upon the satisfaction of additional performance obligations in the contract, such as final delivery of the product. Contract assets are typically derecognized when billed in accordance with the terms of the contract. The Company pools contract assets that share underlying risk characteristics and records an allowance for expected credit losses based on a combination of prior experience, current economic conditions and management’s expectations of future economic conditions, and specific collectibility matters when they arise. Contract assets are presented net of this reserve on the accompanying consolidated balance sheets. For the years ended March 31, 2024, 2023, and 2022 credit loss expense and write-offs related to contract assets were immaterial. Contract liabilities are recorded when customers remit contractual cash payments in advance of the Company satisfying performance obligations under contractual arrangements, including those with performance obligations to be satisfied over a period of time. Contract liabilities other than those pertaining to forward loss reserves are derecognized when or as revenue is recognized. Contract modifications can also impact contract asset and liability balances. When contracts are modified to account for changes in contract specifications and requirements, the Company considers whether the modification either creates new or changes the existing enforceable rights and obligations. Contract modifications that are for goods or services that are not distinct from the existing contract, due to the significant integration with the original good or service provided, are accounted for as if they were part of that existing contract. The effect of a contract modification to an existing contract on the transaction price and the Company’s measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis. When the modifications include additional performance obligations that are distinct and at relative stand-alone selling price, they are accounted for as a new contract and performance obligation, and are recognized prospectively. Contract balances are classified as assets or liabilities on a contract-by-contract basis at the end of each reporting period. The following table summarizes the Company’s contract assets and liabilities balances: March 31, 2024 March 31, 2023 Change Contract assets $ 74,289 $ 86,740 $ ( 12,451 ) Contract liabilities ( 65,358 ) ( 44,558 ) ( 20,800 ) Net contract asset $ 8,931 $ 42,182 $ ( 33,251 ) The change in contract assets is the result of amounts billed in excess of revenue recognized during the year ended March 31, 2024. The change in contract liabilities was the result of the receipt of additional customer advances in excess of revenue recognized during the year ended March 31, 2024. For the period ended March 31, 2024, the Company recognized $ 17,325 of revenue that was included in the contract liability balance at the beginning of the period. Performance Obligations Customers generally contract with the Company for requirements in a segment relating to a specific program, and the Company’s performance obligations consist of a wide range of engineering design services and manufactured components, as well as spare parts and repairs. A single contract may contain multiple performance obligations consisting of both recurring and nonrecurring elements. As of March 31, 2024, the Company has the following unsatisfied, or partially unsatisfied, performance obligations that are expected to be recognized in the future as noted in the table below. The Company expects options to be exercised in addition to the amounts presented below.

The Company is the servicer of the trade accounts receivable under the Securitization Facility. Interest rates are based on the Bloomberg Short Term Bank Yield Index (“BSBY”), plus a 2.25 % fee on the drawn portion and a fee ranging from 0.45 % to 0.50 % on the undrawn portion of the Securitization Facility. The drawn fee may be reduced to 2.00 % depending on the credit rating of the Company. Collateralized letters of credit incur fees at a rate of 0.125 %. The Company secures its trade accounts receivable, which are generally non-interest-bearing, in transactions that are accounted for as borrowings pursuant to ASC 860, Transfers and Servicing . The Company has established a letter of credit facility under the Securitization Facility. Under the provisions of the letter of credit facility, the Company may request the Securitization Facility’s administrator to issue one or more letters of credit that will expire no later than 12 months after the date of issuance, extension or renewal, as applicable. In December 2023, the Company amended the Securitization Facility, decreasing the purchase limit from $ 100,000 to $ 75,000 , modifying certain other terms, and extending the term through December 2025. As of March 31, 2024 , the maximum amount available under the Securitization Facility was $ 75,000 . The actual amount available under the Securitization Facility at any point in time is dependent upon the balance of eligible accounts receivable as well as the amount of letters of credit outstanding. At March 31, 2024 and 2023 , there were $ 0 in borrowings and $ 19,570 and $ 19,753 , respectively, in letters of credit outstanding under the Securitization Facility, primarily to support insurance policies. The agreements governing the Securitization Facility contain restrictions and covenants, including limitations on the making of certain restricted payments; creation of certain liens; and certain corporate acts such as mergers, consolidations and the sale of all or substantially all the Company’s assets. Senior Secured First Lien Notes due 2028 On March 14, 2023, the Company issued $ 1,200,000 principal amount of 9.000 % Senior Secured First Lien Notes due March 15, 2028, pursuant to an indenture among the Company, the Guarantor Subsidiaries, and U.S. Bank National Association, as trustee (the “2028 First Lien Notes”) . The 2028 First Lien Notes were sold at 100 % of the principal amount and have an effective interest yield of 9.000 %. Interest is payable semi-annually in cash in arrears on March 15 and September 15 of each year , commencing on September 15, 2023 . In the twelve months ended March 31, 2024 , the Company recognized a gain of approximately $ 3,400 related to an adjustment to its deferred debt issuance costs, a portion of which related to fiscal 2023. The total issuance costs incurred i n connection with the issuance of the 2028 First Lien Notes were approximately $ 23,000 , which were deferred and are being amortized over the term of the 2028 First Lien Notes. The 2028 First Lien Notes and the guarantees are first lien secured obligations of the Company and the Guarantor Subsidiaries. The 2028 First Lien Notes: (i) rank equally in right of payment to any future senior indebtedness of the Company and Guarantor Subsidiaries; (ii) are effectively senior to all future second lien obligations and all future unsecured indebtedness of the Company and the Guarantor Subsidiaries, but only to the extent of the value of the Collateral (as defined below), and after giving effect to any permitted additional first lien secured obligations and other permitted liens of senior or equal priority); (iii) are senior in right of payment to all future subordinated indebtedness of the Company and the Guarantor Subsidiaries; (iv) are secured by the Collateral on a pari passu basis with any future permitted additional first lien secured obligations, subject to the Collateral Trust Agreement; (v) are effectively subordinated to any existing and future obligations of the Company and the Guarantor Subsidiaries that are secured by assets that do not constitute the Collateral, in each case, to the extent of the value of the assets securing such obligations; and (vi) are structurally subordinated to all existing and future indebtedness and other liabilities of the Company’s existing and future subsidiaries that do not guarantee the 2028 First Lien Notes, including the Securitization Facility. The 2028 First Lien Notes are guaranteed on a full, senior, joint and several basis by each of the Guarantor Subsidiaries. In the future, each of the Company’s domestic restricted subsidiaries (other than any domestic restricted subsidiary that is a receivable subsidiary) that (1) is not an immaterial subsidiary, (2) becomes a borrower under any of its material debt facilities or (3) guarantees (a) any of the Company’s indebtedness or (b) any indebtedness of the Company’s domestic restricted subsidiaries, in the case of either (a) or (b), incurred under any of the Company’s material debt facilities, will guarantee the 2028 First Lien Notes. Under certain circumstances, the guarantees may be released without action by, or consent of, the holders of the 2028 First Lien Notes. The 2028 First Lien Notes and the guarantees are secured, subject to permitted liens, by first-priority liens on substantially all of the Company’s and the Guarantor Subsidiaries’ assets (including certain of the Company’s real estate assets), whether now owned or hereafter acquired, other than certain excluded property, which liens will secure permitted additional first lien obligations on a pari passu basis, subject to the Collateral Trust Agreement (the “Collateral”). Under certain circumstances, the Collateral may be released without action by, or the consent of, the holders of the 2028 First Lien Notes. The 2028 First Lien Notes and the guarantees will not be secured by the assets of Non-Guarantor Subsidiaries, which include the unrestricted subsidiaries to whom certain of the Company’s accounts receivables are and may in the future be sold to support borrowing under the Securitization Facility. A collateral trust agreement (the “Collateral Trust Agreement”) among the Company, the Guarantor Subsidiaries, the Collateral Trustee and U.S. Bank National Association, in its capacity as the trustee for the 2028 First Lien Notes, sets forth therein the relative rights with respect to the Collateral as among the trustee for the 2028 First Lien Notes and certain subsequent holders of first lien obligations and covering certain other matters relating to the administration of security interests. The Collateral Trust Agreement generally controls substantially all matters related to the Collateral, including with respect to decisions, distribution of proceeds or enforcement. Pursuant to the Collateral Trust Agreement, on the issue date of the 2028 First Lien Notes the Collateral Trustee will control certain matters related to the Collateral that the Collateral Trust Agreement specifies are in its discretion. If the Company incurs certain types of additional first lien obligations, the Controlling First Lien Holders (as defined in the Collateral Trust Agreement) will have the right to control decisions relating to the Collateral that are outside the Collateral Trustee’s discretion under the Collateral Trust Agreement and the 2028 Note holders may no longer be in control of such decisions. The Company may redeem the 2028 First Lien Notes, in whole or in part, at any time or from time to time on or after March 15, 2025, at specified redemption prices, plus accrued and unpaid interest, if any, to the redemption date. At any time or from time to time prior to March 15, 2025, the Company may redeem the 2028 First Lien Notes, in whole or in part, at a redemption price equal to 100 % of their principal amount plus a make whole premium, together with accrued and unpaid interest, if any, to the redemption date. In addition, the Company may redeem up to 40 % of the aggregate principal amount of the outstanding 2028 First Lien Notes prior to March 15, 2025, with the net cash proceeds from certain equity offerings at a redemption price equal to 109.000 % of their principal amount, together with accrued and unpaid interest, if any, to the redemption date. The Company may redeem, at any time from time to time before March 15, 2025, up to 10 % of the aggregate principal amount of the notes per annum, at a redemption price equal to 103 % of the aggregate principal amount plus accrued and unpaid interest, if any, to the redemption date. If the Company experiences specific kinds of changes of control, the Company is required to offer to purchase all of the 2028 First Lien Notes at a purchase price of 101 % of their principal amount, plus accrued and unpaid interest, if any, to the date of purchase. The 2028 First Lien Notes Indenture contains covenants that, among other things, limit the ability of the Company and its restricted subsidiaries to: (i) incur additional indebtedness; (ii) pay dividends or make other distributions; (iii) make other restricted payments and investments; (iv) create liens; (v) incur restrictions on the ability of restricted subsidiaries to pay dividends or make certain other payments; (vi) sell assets, including capital stock of restricted subsidiaries; (vii) enter into sale and leaseback transactions; (viii) merge or consolidate with other entities; and (ix) enter into transactions with affiliates. In addition, the 2028 First Lien Notes Indenture requires, among other things, the Company to provide financial and current reports to holders of the 2028 First Lien Notes or file such reports electronically with the SEC. These covenants are subject to a number of exceptions, limitations and qualifications set forth in the Indenture, as well as suspension periods in certain circumstances.

Pursuant to this agreement, in the year ended March 31, 2024, the Company used approximately $ 48,062 to redeem $ 50,000 principal amount of the 2025 Notes.

Financial Instruments Not Recorded at Fair Value Carrying amounts and the related estimated fair values of the Company's long-term debt not recorded at fair value in the accompanying consolidated financial statements are as follows: March 31, 2024 March 31, 2023 Carrying Fair Carrying Fair $ 1,078,199 $ 1,154,245 $ 1,691,782 $ 1,676,879 The fair value of the long-term debt was calculated based on either interest rates available for debt with terms and maturities similar to the Company's existing debt arrangements or broker quotes on the Company's existing debt (Level 2 inputs). Interest paid on indebtedness during the fiscal years ended March 31, 2024, 2023, and 2022, amounted to $ 147,975 , $ 138,464 and $ 137,922 , respectively. The Company also made redemption premium payments of approximately $ 3,600 , $ 26,157 , and $ 9,108 in the years ended March 31, 2024, 2023, and 2022, respectively. As of March 31, 2024, the fiscal year maturities of long-term debt are as follows: 2025 — $ 3,200 ; 2026 — $ 2,838 ; 2027 — $ 2,737 ; 2028 — $ 1,080,737 ; 2029 — $ 1,936 ; and thereafter— $ 3,350 through 2036 .

The Company's policy is to release the tax effects from accumulated other comprehensive loss when all of the related assets or liabilities that gave rise to the accumulated other comprehensive loss (income) have been derecogniz ed. The Company has elected to treat global intangible low-taxed income (“GILTI”) as a period expense. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. When determining the amount of net deferred tax assets that are more likely than not to be realized, the Company assesses all available positive and negative evidence. This evidence includes, but is not limited to, prior earnings history, expected future earnings, carry-back and carry-forward periods and the feasibility of ongoing tax strategies that could potentially enhance the likelihood of the realization of a deferred tax asset. The weight given to the positive and negative evidence is commensurate with the extent the evidence may be objectively verified. As such, it is generally difficult for positive evidence regarding projected future taxable income exclusive of reversing taxable temporary differences to outweigh objective negative evidence of recent financial reporting losses. Based on these criteria and the relative weighting of both the positive and negative evidence available and, in particular, the activity surrounding the Company's prior earnings history, including the forward losses and intangible impairments previously recognized, management determined that it was necessary to establish a valuation allowance against principally all of its net deferred tax assets. Given the objective verifiable negative evidence of a three-year cumulative loss and the weighting of all available positive evidence, the Company excluded projected taxable income (aside from reversing taxable temporary differences) from the assessment of income that could be used as a source of taxable income to realize the deferred tax assets. During fiscal year 2024 , the Company adjusted the valuation allowance against the consolidated net deferred tax asset by $ 113,396 primarily due to utilization of net operating loss carryforwards, deduction of previously disallowed interest expense deductions, utilization of research and development credits previously carried forward, research and development cost amortization, and pension and other postretirement benefit plans. As of March 31, 2024, management determined that it was necessary to maintain a valuation allowance against principally all of its net deferred tax assets. As of March 31, 2024 , the Company has net operating loss carryforwards of $ 181,848 , $ 1,308,319 , and $ 174,723 for U.S. federal, state, and foreign jurisdictions, respectively. All Federal net operating losses have an indefinite carryforward period. State net operating losses begin to expire in 2024 , with a portion classified as indefinite. Approximately $ 6,357 of foreign net operating losses begin to expire in 2027 , and $ 168,366 have an indefinite carryforward period. The Company has been granted income tax holiday as an incentive to attract foreign investment by the Government of Thailand. The tax holidays continue to expire in various years through 2026. The Company does not have any other tax holidays in the jurisdictions in which it operates. The income tax benefit attributable to the tax status of our subsidiaries in Thailand was approximately $ 1,073 or $ 0.01 per diluted share in fiscal 2024 , $ 583 or $ 0.01 per diluted share in fiscal 2023 and $ 415 or $ 0.01 per diluted share in fiscal 2022. In connection with the sale of the Company’s Product Support business, the company does not expect a benefit from this tax holiday program in future periods. At March 31, 2024 , cumulative undistributed earnings of foreign subsidiaries, for which no U.S. income or foreign withholding taxes have been recorded is $ 148,871 . As the Company currently intends to indefinitely reinvest all such earnings, no provision has been made for income taxes that may become payable upon distribution of such earnings, and it is not practicable to determine the amount of the related unrecognized deferred income tax liability. The Company has classified uncertain tax positions as noncurrent income tax liabilities unless expected to be paid in one year. As of March 31, 2024 and 2023 , the total amount of unrecognized tax benefits was $ 12,281 and $ 12,085 , respectively, all of which would impact the effective rate, if recognized. The Company anticipates that total unrecognized tax benefits may be reduced by zero in the next 12 months. With a few exceptions, the Company is no longer subject to U.S. federal, state, or local income tax examinations, or foreign income tax examinations by tax authorities, for fiscal years ended before March 31, 2014. As of March 31, 2024, the Company is not subject to any income tax examinations. The Company believes appropriate provisions for all outstanding issues have been made for all jurisdictions and all open years. There are no material interest and penalties accrued as of the year ended March 31, 2024. A reconciliation of the liability for uncertain tax positions, which are included in deferred taxes for the fiscal years ended March 31, 2024, 2023, and 2022 follows: Year ended March 31, 2024 2023 2022 Beginning balance $ 12,193 $ 11,978 $ 11,750 Adjustments for tax positions related to the current year 371 223 228 Adjustments for tax positions of prior years ( 348 ) ( 8 ) 0 Ending balance $ 12,216 $ 12,193 $ 11,978

Equity [Abstract]
Stockholders' Deficit	13. STOCKHOLDERS' DEFICIT In March 2022, the Company adopted a tax benefits preservation plan (the " Plan") designed to preserve Triumph’s ability to utilize its net operating loss carryforwards and other tax attributes (collectively, "Tax Benefits"). The Plan replaced a similar plan that was adopted in March 2019 and which expired in March 2022. The Company obtained stockholder approval for the Plan in July 2022 at its annual meeting of stockholders. Under the Plan, Triumph declared a dividend distribution of one right (a “Right”) for each share of its common stock outstanding at the close of business on March 21, 2022. The Plan will expire on March 13, 2025. The Rights also will expire: (i) if the Rights are redeemed or exchanged as provided in the Plan; (ii) if the Board determines that the Plan is no longer necessary or desirable for the preservation of the Tax Benefits; or (iii) if the Board determines that no Tax Benefits, once realized, as applicable, may be carried forward (in which case, the Rights will expire on the first date of the relevant taxable year for which such determination is made). Pursuant to the Plan, if a stockholder (or group) becomes a 4.9 % stockholder without meeting certain customary exceptions, the Rights become exercisable and entitle stockholders (other than the 4.9 % stockholder or group causing the rights to become exercisable) to purchase additional shares of Triumph at a significant discount, resulting in significant dilution in the economic interest and voting power of the 4.9 % stockholder or group causing the Rights to become exercisable. Stockholders owning 4.9 % or more of Triumph’s outstanding shares at the time the Plan was adopted were grandfathered and will only cause the Rights to distribute and become exercisable if they acquire an additional one percent or more of Triumph’s outstanding shares. Under the Plan, the Board has the ability to determine in its sole discretion that any person shall not be deemed an acquiring person and therefore that the Rights shall not become exercisable if such person becomes a 4.9 % stockholder. The adoption of the Plan and the dividend distribution did not have an impact on the Company’s consolidated financial statements. In 2014, the Company's Board of Directors authorized an increase in the Company's existing stock repurchase program by up to 5,000,000 shares of its common stock in addition to the 500,800 shares authorized under prior authorizations. As of March 31, 2024 , the Company remains able to purchase an additional 2,277,789 shares. Repurchases may be made from time to time in open market transactions, block purchases, privately negotiated transactions or otherwise at prevailing prices. No time limit has been set for completion of the program. The holders of the common stock are entitled to one vote per share on all matters to be voted upon by the stockholders of Triumph. The Company has preferred stock of $ 0.01 par value, 250,000 shares authorized. At March 31, 2024 and 2023 , zero shares of preferred stock were outstanding. Accumulated Other Comprehensive Loss Changes in accumulated other comprehensive loss ("AOCI") by component for the years ended March 31, 2024 and 2023, were as follows: Currency Unrealized Gains Defined Benefit Total (1) March 31, 2022 $ ( 47,933 ) $ ( 270 ) $ ( 415,151 ) $ ( 463,354 ) AOCI before reclassifications ( 1,273 ) 2,265 ( 113,232 ) ( 112,240 ) Amounts reclassified from AOCI — ( 778 ) 21,726 (2) 20,948 Net current period OCI ( 1,273 ) 1,487 ( 91,506 ) ( 91,292 ) March 31, 2023 ( 49,206 ) 1,217 ( 506,657 ) ( 554,646 ) AOCI before reclassifications 5,057 796 12,511 18,364 Amounts reclassified from AOCI — ( 1,944 ) 21,157 (2) 19,213 Net current period OCI 5,057 ( 1,148 ) 33,668 37,577 March 31, 2024 $ ( 44,149 ) $ 69 $ ( 472,989 ) $ ( 517,069 ) (1) Net of tax.

Earnings Per Share [Abstract]
Earnings (Loss) per Share	14. EARNINGS (LOSS) PER SHARE The calculation of basic earnings per share is based on (loss) income from continuing operations, income from discontinued operations, or net income (loss) divided by the weighted average number of common shares considered outstanding during the periods. The calculation of diluted earnings per share reflects the effect of all potentially dilutive securities (principally outstanding warrants and outstanding restricted stock units) and is based on (loss) income from continuing operations, income from discontinued operations, or net income (loss) divided by the diluted weighted average number of common shares considered outstanding during the periods. As disclosed in Note 2, the Warrants permitted the tendering of Designated Notes in payment of the exercise price. In computing diluted earnings per share, the Company applies the if-converted method to the warrants and such warrants are assumed to be exercised and the Designated Notes are assumed to be tendered unless tendering cash would be more advantageous to the warrant holder. Interest (net of tax) on any Designated Notes assumed to be tendered is added back as an adjustment to the (loss) income from continuing operations numerator as the warrants are transactions related to continuing operations. The (loss) income from continuing operations numerator is also adjusted for any nondiscretionary adjustments based on income (net of tax) including, for example, warrant remeasurement gains and losses recognized in the period. If cash exercise is more advantageous, the Company applies the treasury stock method to the warrants when calculating diluted earnings per share. The following is a reconciliation between the weighted average outstanding shares used in the calculation of basic and diluted earnings per share: Year ended March 31, (in thousands) 2024 2023 2022 Numerator: Numerator for basic earnings per share: (Loss) income from continuing operations $ ( 34,467 ) $ 72,417 $ ( 50,377 ) Effect of Dilutive Securities: Warrants — ( 3,626 ) — Numerators for diluted (loss) earnings per share: (Loss) income from continuing operations available to common stockholders after assumed conversions $ ( 34,467 ) $ 68,791 $ ( 50,377 ) Income from discontinued operations, net of tax expense 546,851 17,176 7,619 Net income (loss) available to common stockholders after assumed conversions $ 512,384 $ 85,967 $ ( 42,758 ) Denominator: Denominator for basic earnings per share Weighted average common shares outstanding - basic 74,149 65,021 64,538 Effect of Dilutive Securities: Warrants — 6,371 — Restricted stock units — 329 — Dilutive potential common shares — 6,700 — Denominator for basic (loss) earnings per share Weighted average common shares outstanding - diluted 74,149 71,721 64,538 (Loss) earnings per share: Basic (loss) earnings per share - continuing operations $ ( 0.46 ) $ 1.12 $ ( 0.78 ) Basic earnings per share - discontinued operations 7.38 0.26 0.12 Basic earnings (loss) per share $ 6.92 $ 1.38 $ ( 0.66 ) Diluted (loss) earnings per share - continuing operations $ ( 0.46 ) $ 0.96 $ ( 0.78 ) Diluted earnings per share - discontinued operations 7.38 0.24 0.12 Diluted earnings (loss) per share $ 6.92 $ 1.20 $ ( 0.66 ) For the fiscal years ended March 31, 2024, 2023, and 2022 , the shares that could potentially dilute earnings per share in the future but were not included in diluted weighted average common shares outstanding because to do so would have been anti-dilutive were immaterial.

Retirement Benefits [Abstract]
Employee Benefit Plans	15. EMPLOYEE BENEFIT PLANS Defined Contribution Pension Plan The Company sponsors a defined contribution 401(k) plan, under which salaried and certain hourly employees may defer a portion of their compensation. Eligible participants may contribute to the plan up to the allowable amount as determined by the plan of their regular compensation before taxes. The Company generally matches contributions at a rate of 75 % of the first 6 % of compensation contributed by the participant. All contributions and Company matched contributions are invested at the direction of the employee in one or more investment options offered under the plan. Company matching contributions vest immediately and aggregated to $ 9,143 , $ 9,329 , and $ 2,998 for the fiscal years ended March 31, 2024, 2023, and 2022, respectively. Defined Benefit Pension and Other Postretirement Benefit Plans The Company sponsors several defined benefit pension plans covering some of its employees. Most employees are ineligible to participate in the plans or have ceased to accrue additional benefits under the plans based upon their service to the Company or years of service accrued under the defined benefit pension plans. Benefits under the defined benefit plans are based on years of service and, for most non-represented employees, on average compensation for certain years. It is the Company's policy to fund at least the minimum amount required for all qualified plans, using actuarial cost methods and assumptions acceptable under applicable government regulations, by making payments into a separate trust. The Company has in the past contributed and may in the future contribute shares of its common stock to this separate trust which would reduce the cash contribution required by the Company. In addition to the defined benefit pension plans, the Company provides other postretirement benefits ("OPEB") in the form of certain healthcare benefits for eligible retired employees. Such benefits are unfunded as of March 31, 2024. No active employees are eligible for these benefits. The vast majority of eligible retirees receive a fixed-dollar benefit they can use to purchase healthcare services. A small number of eligible retirees receive traditional retiree medical benefits for which the Company pays all premiums. All retirees who are eligible for these traditional benefits are Medicare-eligible. Current plan documents reserve the right to amend or terminate the plans at any time, subject to applicable collective bargaining requirements for represented employees. In accordance with the Compensation – Retirement Benefits topic of ASC 715, the Company has recognized the funded status of the benefit obligation as of March 31, 2024 and 2023, on the accompanying consolidated balance sheets. The funded status is measured as the difference between the fair value of the plans' assets and the pension benefit obligation or accumulated postretirement benefit obligation of the plan. The majority of the plan assets are publicly traded investments, which were valued based on the market price as of the measurement date. Investments that are not publicly traded were valued based on the estimated fair value of those investments based on the Company’s evaluation of data from fund managers and comparable market data or using the net asset value as a practical expedient. The following tables set forth the Company's consolidated defined benefit pension plans for its union and non-union employees as of March 31, 2024 and 2023, and the amounts recorded on the consolidated balance sheets at March 31, 2024 and 2023. Company contributions include amounts contributed directly to plan assets and indirectly as benefits paid from the Company's assets. Benefit payments reflect the total benefits paid from the plans and the Company's assets. Information on the plans includes both the domestic qualified and nonqualified plans and the foreign qualified plans.

The discount rate is determined annually as of each measurement date, based on a review of yield rates associated with long-term, high-quality corporate bonds. At the end of each year, the discount rate is primarily determined using the results of bond yield curve models based on a portfolio of high-quality bonds matching notional cash inflows with the expected benefit payments for each significant benefit plan. The expected return on plan assets is determined based on a market-related value of assets ("MRVA"), which is a smoothed asset value. For fixed income securities, the MRVA is determined using the fair value of the fixed income assets. For all other classes of pension assets, the MRVA is calculated by recognizing investment performance that is different from that expected on a straight-line basis over five years. Actuarial gains and losses are amortized over the average remaining life expectancy of inactive participants for plans that are predominantly inactive and over the expected future service for active participants for other plans, but only to the extent unrecognized gains or losses exceed a corridor equal to 10 % of the greater of the projected benefit obligation or market-related value of assets. The Company estimates the service and interest cost of its pension and OPEB plans by using the specific spot rates derived from the yield curve used to discount the cash flows reflected in the measurement of the benefit obligation. The Company believes this approach provides a precise measurement of service and interest costs due to the correlation between projected benefit cash flows to the corresponding spot yield curve rates. During the fiscal year ended March 31, 2024, the Society of Actuaries did not release a new mortality projection scale, and therefore the mortality projection scale remains unchanged. The Company elected to make no changes to the mortality assumptions due to the continued uncertainty of the impact of the COVID-19 pandemic on the long-term mortality rate. The projected benefit obligation assumptions impacting net actuarial gain consist of changes in discount and prescribed lump sum mortality rates, as well as changes to the deferred vested participation and commencement age assumptions. As required under ASC 715, the Company remeasures plan assets and obligations during an interim period whenever a significant event occurs that results in a material change in the net periodic pension cost. The determination of significance is based on judgment and consideration of events and circumstances impacting the pension costs. The following summarizes the key events whose effects on net periodic benefit cost and obligations are included in the tables above: • On March 21, 2022, the Company elected to purchase annuities and settle the pension obligations for approximately 2,500 retired participants in its qualified U.S. pension plan. As a result of this transaction approximately $ 52,256 of plan assets and $ 51,418 of plan liabilities were transferred to the Nationwide Life and Annuity Insurance Company. The settlement resulted in the recognition of prior noncash actuarial losses of approximately $ 32,116 in the year ended March 31, 2022. The settlement's impact on the accompanying consolidated balance sheets was insignificant as the plan's assets were materially consistent with the settled pension obligation. • Effective August 31, 2021, the Company settled the fully-funded pension obligation it had retained subsequent to its fiscal year 2019 divestiture of Triumph Geared Solutions - Toronto. The settlement resulted in the recognition of prior noncash actuarial losses of approximately $ 3,826 in the year ended March 31, 2022. The settlement's impact on the accompanying consolidated balance sheets was insignificant as the plan's assets were materially consistent with the settled pension obligation. • Upon the completion of the sale of the composites and large structure manufacturing operations as disclosed in Note 3, the expected future service of certain defined benefit pension plan participants was curtailed and certain participants became eligible for subsidized early retirement benefits under the terms of the relevant plan. As a result, the Company performed an interim remeasurement and recognized a onetime pension curtailment charge of approximately $ 16,024 which is presented in non-service defined benefit income on the accompanying consolidated statement of operations for year ended March 31, 2022. Additionally, the Company accrued a Withdrawal Liability (as defined below), and recognized in non-serviced defined benefit income, of $ 14,644 as a result of the exit of its Spokane, Washington, composites manufacturing operations in the year ended March 31, 2023. Refer to Note 17 for further information. Expected Pension Benefit Payments The total estimated future benefit payments for the pension plans are expected to be paid from the plan assets and company funds. Estimated future benefit payments from plan assets and Company funds for the next ten fiscal years are as follows: Year Pension 2025 $ 155,839 2026 141,299 2027 137,467 2028 133,892 2029 129,551 2030 - 2034 588,180 Plan Assets, Investment Policy and Strategy The table below sets forth the Company's target asset allocation for fiscal 2024 and the actual asset allocations at March 31, 2024 and 2023. Actual Allocation Target Allocation March 31, Asset Category Fiscal 2024 2024 2023 Equity securities 50 % - 60 % 58 % 55 % Fixed income securities 30 % - 40 % 31 34 Alternative investment funds 0 % - 10 % 10 10 Other 0 % - 5 % 1 1 Total 100 % 100 % Pension plan assets are invested in various asset classes that are expected to produce a sufficient level of diversification and investment return over the long-term. The investment goals are to exceed the assumed actuarial rate of return over the long-term within reasonable and prudent levels of risks and to meet future obligations. Asset/liability studies are conducted on a regular basis to provide guidance in setting investment goals for the pension portfolio and its asset allocation. The asset allocation aims to prudently achieve a strong, risk-adjusted return while seeking to minimize funding level volatility and improve the funded status of the plans. The pension plans currently employ a liability-driven investment ("LDI") approach, where assets and liabilities move in the same direction. The goal is to limit the volatility of the funding status and cover part, but not all, of the changes in liabilities. Most of the liabilities' changes are due to interest rate movements. To balance expected risk and return, allocation targets are established and monitored against acceptable ranges. All investment policies and procedures are designed to ensure that the plans' investments are in compliance with the Employee Retirement Income Security Act of 1974 ("ERISA"). Guidelines are established defining permitted investments within each asset class. Each investment manager has contractual guidelines to ensure that investments are made within the parameters of their asset class or in the case of multi-asset class managers, the parameters of their multi-asset class strategy. Certain investments are not permitted at any time, including investment directly in employer securities and uncovered short sales. The tables below provide the fair values of the Company's plan assets at March 31, 2024 and 2023, by asset category. The table also identifies the level of inputs used to determine the fair value of assets in each category (refer to Note 2 for definition of levels).

Public equity securities, including common stock, are primarily valued using a market approach based on the closing fair market prices of identical instruments in the principal market on which they are traded. Commingled funds that are open-ended mutual funds for which the fair value per share is determined and published by the respective mutual fund sponsor and is the basis for current observable transactions are categorized as Level 1 fair value measures. Investments in commingled funds and private equity and infrastructure funds are carried at net asset value ("NAV") as a practical expedient to estimate fair value. The NAV is the total value of the fund divided by the number of shares outstanding. Adjustments to NAV, if any, are determined based on evaluation of data provided by fund managers, including valuation of the underlying investments derived using inputs such as cost, operating results, discounted future cash flows and market-based comparable data. In accordance with ASC 820-10, investments that are measured at NAV practical expedient are not classified in the fair value hierarchy; however, their fair value amounts are presented in these tables to permit reconciliation of the fair value hierarchy to the total plan assets disclosed in this footnote. Corporate, government agency bonds and mortgage-backed securities are primarily valued using a market approach with inputs that include broker quotes, benchmark yields, base spreads and reported observable trades for identical or comparable instruments. Other investments include insurance contracts primarily valued based on estimates of the premium required to acquire similar insurance contracts using market-based comparable data. Assumptions and Sensitivities The discount rate is determined as of each measurement date, based on a review of yield rates associated with long-term, high-quality corporate bonds. The calculation separately discounts benefit payments using the spot rates from a long-term, high-quality corporate bond yield curve. The effect of a 25 basis-point change in discount rates as of March 31, 2024, is shown below: Pension Increase of 25 basis points Obligation * $ ( 31,238 ) Net periodic expense 140 Decrease of 25 basis points Obligation * $ 32,433 Net periodic expense ( 165 ) * Excludes impact to plan assets due to the LDI investment approach discussed above under "Plan Assets, Investment Policy and Strategy." The long-term rate of return assumption represents the expected average rate of earnings on the funds invested to provide for the benefits included in the benefit obligations. The long-term rate of return assumption is determined based on a number of factors, including historical market index returns, the anticipated long-term asset allocation of the plans, historical plan return data, plan expenses and the potential to outperform market index returns. For fiscal 2025, the expected long-term rate of return is 5.5 % - 8.00 % . Anticipated Contributions to Defined Benefit In the year ended March 31, 2024, the Company contributed 3,200,000 shares of common stock to the separate pension plan trust with an aggregate contribution value of approximately $ 39,136 on the contribution date. The Company expects to contribute approximately $ 23,000 to its qualified U.S. defined benefit pension plans during fiscal 2025 . No plan assets are expected to be returned to the Company in fiscal 2025 .

Share-Based Payment Arrangement [Abstract]
Stock Compensation Plans	16. STOCK COMPENSATION PLANS The Company has stock incentive plans under which employees and non-employee directors may be granted equity awards in the form of stock options with an exercise price equal to the fair value of the Company’s stock on the grant date or in the form of restricted stock or restricted stock units that vest pursuant to service conditions and, in some cases, performance and/or market conditions. The stock incentive and compensation plans under which outstanding equity awards have been granted to employees, officers, and non-employee directors are the Triumph Group 2018 Equity Plan (the "2018 Plan"), the Triumph Group 2013 Equity and Cash Incentive Plan (the “2013 Plan”), the 2016 Directors’ Equity Compensation Plan, as amended (the “Directors’ Plan”), and the Amended and Restated Directors’ Stock Incentive Plan (the “Prior Directors’ Plan”). The Prior Directors’ Plan expired by its terms during fiscal 2017. The current stock incentive and compensation plans used for future awards are the 2018 Plan and the Directors’ Plan. New grants under the 2013 Plan ceased upon the approval of the 2018 Plan in fiscal 2019, and the 2013 Plan expired by its terms during fiscal 2024. The 2018 Plan and the Directors’ Plan are collectively referred to in this note as the plans. Management and the compensation committee have utilized restricted stock units as its primary form of share-based incentive compensation. Restricted stock units that vest solely pursuant to service conditions generally vest on a graded basis over a three year period and are subject to forfeiture should the grantee’s employment be terminated prior to an applicable vesting date. Management and the compensation committee have also granted restricted stock units, referred to herein as performance restricted stock units, that vest pursuant to a combination of service conditions as well as market and performance conditions. Such awards generally vest, subject to specific market and/or performance conditions, on a cliff vesting basis at the end of a three year performance period . The market and performance conditions may result in the awards vesting below target, including zero vesting awards if certain threshold vesting conditions are not met, or up to 300 % of the number of awards granted, if certain vesting conditions are exceeded. The share-based payment expense arising from restricted stock unit expense is included in capital in excess of par value. The fair value of restricted stock units awards subject only to service conditions or service and performance conditions is determined by the product of the number of shares granted and the grant date market price of the Company's common stock, adjusted for material non-public information that the Company may be aware of as of the grant date, if any. The fair value of restricted stock units awards that contain market conditions is determined by the product of the number of shares granted and the grant date fair value of such an award value using a Monte Carlo valuation methodology. The fair value of share-based compensation granted to employees was $ 11,775 , $ 13,728 , and $ 14,129 during the fiscal years ended March 31, 2024, 2023, and 2022, respectively. The fair value of restricted stock unit awards is expensed on a straight-line basis over the requisite service period which is typically the vesting period. The Company recognized $ 9,445 , $ 8,913 and $ 9,782 of share-based compensation expense during the fiscal years ended March 31, 2024, 2023, and 2022, respectively. The Company has classified share-based compensation within selling, general and administrative expenses to correspond with the same line item as the majority of the cash compensation paid to the employees receiving share-based compensation. At March 31, 2024 and 2023, 1,653,843 shares and 979,855 shares of common stock, respectively, were available for issuance under the plans. A summary of the status of the Company's non-vested restricted stock units as of March 31, 2024, and changes during the fiscal year ended March 31, 2024, is presented below. Shares Weighted- Non-vested restricted stock units at March 31, 2023 1,513,196 $ 16.01 Granted 1,019,300 11.55 Vested ( 489,342 ) 13.73 Forfeited ( 98,143 ) 13.31 Non-vested restricted stock units at March 31, 2024 1,945,011 $ 14.38 The fair value of employee restricted stock units which vested during fiscal 2024, 2023 and 2022 was $ 6,718 , $ 9,247 , and $ 7,453 , respectively. Expected future compensation expense on restricted stock units, net of expected forfeitures, is approximately $ 5,227 , which is expected to be recognized over the remaining weighted average vesting period of approximately 1.5 years.

Commitments And Contingencies [Abstract]
Commitments and Contingencies	17. COMMITMENTS AND CONTINGENCIES Environmental Matters Certain of the Company's current or former operations and facilities are subject to a number of federal, state, local and foreign environmental laws and regulations. In August 2023, a panel of three arbitrators made an interim decision in an ongoing arbitration between Triumph Aerostructures, LLC (“TAS”), a wholly owned subsidiary of the Company, and Northrop Grumman Systems Corporation (“Northrop”) related to ongoing future responsibility for environmental remediation costs at four formerly occupied properties that had been previously operated by Northrop. Although the interim decision indicated that TAS would have certain ongoing responsibility for remediation at the properties, neither the agreement nor the interim decision provides a mechanism for the transfer of remediation responsibilities to TAS. While the parties continue to dispute liability for remediation, from a regulatory perspective, TAS is not a party to any regulatory order for three of the four properties, although TAS, along with Northrop, is party to the regulatory order for the fourth property. Approximately $ 1,300 has been accrued as a legal judgment loss and is management's best estimate of the remediation costs at the fourth property. While final resolution of this matter remains uncertain, the ultimate impact on operations could be in the range of a loss of up to $ 39,000 , with such loss resulting in annual cash expenditures not likely to exceed $ 2,000 to $ 3,000 in a given year. In March 2024, the panel of arbitrators made a second interim decision in the arbitration between TAS and Northrop indicating that although TAS had responsibility for certain remediation costs at the four formerly occupied properties that had been already incurred by Northrop, the panel was unable to affix an amount of damages to Northrop for those costs and asked the parties to meet and confer regarding those damages. Northrop had indicated during the second phase of the arbitration that it believed its damages incurred through December 31, 2023 to be approximately $ 12,000 , however, Northrop did not substantiate its damages. TAS maintains that Northrop has not proven its damages after opportunity to do so in the second phase of the arbitration. The Company has accrued a liability of approximately $ 6,000 as a result of the second interim decision which is included within legal contingencies loss on the accompanying consolidated statement of operations for the year ended March 31, 2024. It is anticipated that further action by the panel will occur in fiscal 2025. TAS intends to vigorously defend itself in this matter, including potentially seeking to set aside any adverse decision from the arbitration panel. Commercial Disputes and Litigation Throughout the course of the Company’s programs, disputes with suppliers or customers could and have arisen regarding unique contractual requirements, quality, costs or impacts to production schedules. If the Company is unable to successfully and equitably resolve such claims and assertions, its business, financial condition, results of operations, customer relationships and related transactions could be materially adversely affected. In the ordinary course of business, the Company is involved in other disputes, claims and lawsuits with employees, suppliers and customers, as well as governmental and regulatory inquiries, that it deems to be immaterial. Some may involve claims or potential claims of substantial damages, fines, penalties or injunctive relief. While the Company cannot predict the outcome of any pending or future litigation or proceeding and no assurances can be given, the Company does not believe that any pending matter will have a material effect, individually or in the aggregate, on its financial position or results of operations. Divestitures, Disposals, Guarantees, and Indemnifications As disclosed in Note 3, we have engaged in a number of divestitures. In connection with divestitures and related transactions, the Company from time to time has indemnified and has been indemnified by third parties against certain liabilities that may arise in connection with, among other things, business activities prior to the completion of the respective transactions. The term of these indemnifications, which typically pertain to environmental, tax and product liabilities, is generally indefinite. As of March 31, 2024, no indemnification assets or liabilities have been recorded. As it relates to certain divestitures, disputes have arisen or may continue to arise between the Company and the acquirer subsequent to the completion and closing of the divestiture transaction. Such disputes have included or may include amounts payable to or from the buyer for closing working capital adjustments to the purchase price as well as claims regarding alleged violations of contractual terms, representations, and warranties of the sale agreements, among other matters. The outcome of such disputes typically involve negotiations between the Company and the acquirer, but could also lead to litigation between the parties, including as disclosed further below, and the ultimate claims made by the parties against each other could be material. As of March 31, 2024, we have accrued for our estimate of probable losses associated with such disputes, but losses in excess of those currently accrued could be incurred and may be material. The Company has received notification of claims which allege certain bases for indemnification and damages relating to certain divestitures. The relevant agreements generally contain limits on certain damages that may be payable under the relevant agreements. For example, the divestiture agreement relating to the sale of the Red Oak facility specified that representations and warranties insurance would be the sole and exclusive remedy for breach of representations and warranties except in the case of fraud. By way of further example, the divestiture agreement relating to the sale of the Stuart facility contains an $ 18,750 general cap on breaches of representations (other than certain specified representations) and a $ 25,000 cap on breaches of certain specified representations related to contracts and product warranties, in each case absent certain circumstances, including fraud or breaches of fundamental or tax representations. As disclosed in Note 3, on June 16, 2023, the Company entered into a settlement agreement with the buyer of the Stuart facility resolving a working capital dispute with the buyer resulting in an amount of $ 2,400 payable to the Company and resolving claims by the buyer related to the accounts payable representation and warranty under the purchase agreement resulting in an amount of $ 9,200 payable to the buyer, with such amount applicable to the general cap referred to above. The amounts were settled on a net basis by the Company paying $ 6,800 to the buyer. The purchaser of the Stuart facility also commenced litigation against the Company on December 12, 2023, seeking additional indemnification for damages claimed to be approximately $ 130,000 for losses allegedly arising from the knowing breach of certain representations and warranties regarding the financial condition of TAS and the products manufactured by TAS and alleged failures to disclose known and widespread paint issues and certain supplier and production issues at the facility prior to the closing. While the Company cannot predict the outcome of any pending or future litigation, proceeding, or claim and no assurances can be given, the Company intends to vigorously defend claims brought against it and does not believe that any pending matter will have a material effect, individually or in the aggregate, on its financial position or results of operations. If the Company is unable to successfully and equitably resolve such claims and assertions, its business, financial condition, and results of operations could be materially adversely affected. Additionally, in connection with certain divestitures, the Company has obtained customer consent to assign specified long-term contracts to the acquirer of the divested business by entering into consent-to-assignment agreements among the customer, the acquirer, and the Company. Pursuant to certain of these agreements, the Company remains a co-obligor under the contract pursuant to guarantee agreements with the customer that predate the divestiture transaction. The term of these obligations typically covers a period of 2 to 5 years from the date of divestiture. There is no limitation to the maximum potential future liabilities under these contracts; however, the Company is typically indemnified by acquirers against such losses that may arise from the acquirers’ failure to perform under the assigned contracts. As of March 31, 2024 , no related indemnification assets or liabilities or guarantee liabilities have been recorded, and the Company has not been called upon to act as co-obligor under such arrangements through that date. Also, in connection with certain divestitures, the Company has assigned lease facility agreements to the acquirers and entered into agreements to act as a co-obligor under the lease agreement in the event of non-performance under the lease by the assignee. The Company is generally indemnified by the assignee or other third party to the transaction. On May 2, 2023, the Company received a letter from a lessor associated with one such transaction to assert the lessor’s rights against the Company as guarantor. The lease payment associated with the lease is approximately $ 130 per month over a lease term ending December 31, 2031, although the landlord has acknowledged its duty to mitigate damages by re-leasing the property. The Company expects to be fully indemnified for any amounts payable under such guarantee. As the Company has completed the disposal of certain facilities, it may be exposed to additional costs such as environmental remediation obligations, lease termination costs, or customer or supplier claims which may have a material effect on its financial position or results of operations when such matters arise and a reasonable estimate of the costs can be made. For example, in the year ended March 31, 2023, the Company withdrew from the IAM National Pension Fund (the “Fund), which is a multiemployer pension plan to which the Company previously contributed on behalf of certain of its represented employees. Such withdrawal occurred as part of the Company’s exit of its Spokane, Washington, composites manufacturing operations. In April 2023, the Company received a letter from the Fund confirming the Company’s complete withdrawal from the Fund and indicating that the Company’s portion of the unfunded vested benefits (the “Withdrawal Liability”) was estimated to be approximately $ 14,644 , payable in quarterly installments of approximately $ 400 over a period of approximately thirteen years. The Withdrawal Liability is subject to further adjustment based on the finalization of the Fund’s actuarial valuation for the plan year ending December 31, 2021, (i.e., the applicable plan year preceding the date of the Company’s withdrawal). As of March 31, 2024 , the Company's liability for this obligation on the accompanying consolidated balance sheet is approximately $ 13,912 , representing its estimate of the remaining obligation before interest based on the letter received from the Fund. The Company is in the process of reviewing and responding to the withdrawal liability assessment, and it is possible the Withdrawal Liability could be reduced during that process.

Customer Concentration

Customer Concentration [Abstract]
Customer Concentration	18. CUSTOMER CONCENTRATION Trade and other receivables from The Boeing Company ("Boeing") represented approximately 14 % and 13 % of total trade and other receivables as of March 31, 2024 and 2023, respectively. Trade and other receivables from Daher Aerospace Inc. ("Daher") include receivables that largely correspond with payables associated with transition services and represented approximately 20 % as of March 31, 2023. The Company had no other significant concentrations of credit risk. Sales to Boeing for fiscal 2024 were $ 279,956 , or 23 % of net sales, of which $ 168,038 and $ 111,918 were from Systems & Support and Interiors, respectively. Sales to Boeing for fiscal 2023 were $ 259,343 , or 23 % of net sales, of which $ 154,404 and $ 104,939 were from Systems & Support and Interiors, respectively. Sales to Boeing for fiscal 2022 were $ 464,043 , or 37 % of net sales, of which $ 130,123 and $ 333,920 were from Systems & Support and Interiors, respectively. No other single customer accounted for more than 10 % of the Company's net sales; however, the loss of any significant customer, including Boeing, could have a material adverse effect on the Company and its operating subsidiaries. The Company currently generates a majority of its revenue from clients in the commercial aerospace industry and the military. The Company's growth and financial results are largely dependent on continued demand for its products and services from clients in these industries. When these industries experience a downturn, it is possible that customers in these sectors may conduct less business with the Company.

Segment Reporting [Abstract]
Segments	20. SEGMENTS The Company reports financial performance based on the following two reportable segments: Systems & Support and Interiors. The Company’s reportable segments are aligned with how the business is managed, and the Company's views of the markets it serves. The Chief Operating Decision Maker (the "CODM") evaluates performance and allocates resources based upon review of segment information. The CODM utilizes earnings before interest, income taxes, consideration payable to customer related to divestiture, depreciation and amortization, and pension (“Adjusted EBITDAP”) as a primary measure of segment profitability to evaluate the performance of its segments and allocate resources. Segment Adjusted EBITDAP is total segment revenue reduced by operating expenses (less depreciation and amortization) identifiable with that segment. Corporate includes general corporate administrative costs and any other costs not identifiable with one of the Company’s segments. The Company does not accumulate net sales information by product or service or groups of similar products and services, and therefore the Company does not disclose net sales by product or service because to do so would be impracticable.

Accounting Policies [Abstract]
Cash and Cash Equivalents	Cash and Cash Equivalents Cash equivalents consist of highly liquid investments with a maturity of three months or less at the time of purchase. Fair value of cash equivalents approximates carrying value.
Trade and Other Receivables, net	Trade and Other Receivables, net Trade and other receivables are recorded net of an allowance for expected credit losses. Trade and other receivables include amounts billed and currently due from customers. The Company performs ongoing credit evaluations of its customers and generally does not require collateral. The Company pools receivables that share underlying risk characteristics and records the allowance for expected credit losses based on a combination of prior experience, current economic conditions and management’s expectations of future economic conditions, and specific collectibility matters when they arise. The Company writes off balances against the allowance for expected credit losses when collectibility is deemed remote. The Company's trade and other receivables are exposed to credit risk; however, the risk is limited due to the diversity of the customer base. For the years ended March 31, 2024, 2023, and 2022, credit loss expense and write-offs were immaterial. Trade and other receivables, net composed of the following: March 31, 2024 2023 Total trade receivables $ 139,012 $ 119,583 Other receivables 4,033 42,010 Total trade and other receivables 143,045 161,593 Less: Allowance for credit losses ( 4,773 ) ( 5,477 ) Total trade and other receivables, net $ 138,272 $ 156,116
Goodwill and Intangible Assets	Goodwill and Intangible Assets The Company accounts for goodwill and intangible assets in accordance with ASC 350, Intangibles—Goodwill and Other . Under ASC 350, goodwill and intangible assets with indefinite lives are not amortized; rather, they are tested for impairment on at least an annual basis. Intangible assets with finite lives are amortized over their useful lives. The Company assesses whether goodwill impairment exists using both the qualitative and quantitative assessments. The qualitative assessment involves determining whether events or circumstances exist that indicate it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill. If based on this qualitative assessment the Company determines it is more likely than not that the fair value of a reporting unit is less than its carrying amount or if the Company elects not to perform a qualitative assessment, a quantitative assessment is performed as required by ASC 350 to determine whether a goodwill impairment exists at the reporting unit. The quantitative test is used to compare the carrying amount of the reporting unit's assets to the fair value of the reporting unit. If the fair value exceeds the carrying value, no further evaluation is required, and no impairment loss is recognized. If the carrying amount exceeds the fair value, then an impairment loss occurs. The impairment is measured by using the amount by which the carrying value exceeds the fair value not to exceed the amount of recorded goodwill. The determination of the fair value of its reporting units is based, among other things, on estimates of future operating performance of the reporting unit being valued. The Company is required to complete an impairment test for goodwill and record any resulting impairment losses at least annually. Changes in market conditions, among other factors, may have an impact on these estimates and require interim impairment assessments. When performing the quantitative impairment test, the Company's methodology includes the use of an income approach which discounts future net cash flows to their present value at a rate that reflects the Company's cost of capital, otherwise known as the discounted cash flow method ("DCF"). These estimated fair values are based on estimates of future cash flows of the businesses. Factors affecting these future cash flows include the continued market acceptance of the products and services offered by the businesses, the development of new products and services by the businesses and the underlying cost of development, the future cost structure of the businesses and future technological changes. The Company also incorporates market multiples for comparable companies in determining the fair value of its reporting units. Any such impairment would be recognized in full in the reporting period in which it has been identified. The fair value estimates resulting from the application of these methodologies are based on inputs classified within Level 3 of the fair value hierarchy, as described below. During the fourth quarter of the fiscal years ended March 31, 2024 and 2023, the Company performed its annual goodwill impairment assessment for each of its reporting units with no impairment identified. Finite-lived intangible assets are amortized over their useful lives ranging from 10 to 30 years . The Company continually evaluates whether events or circumstances have occurred that would indicate that the remaining estimated useful lives of long-lived assets, including intangible assets, may warrant revision or that the remaining balance may not be recoverable. Long-lived assets are evaluated for indicators of impairment. When factors indicate that long-lived assets, including intangible assets, should be evaluated for possible impairment, an estimate of the related undiscounted cash flows over the remaining life of the long-lived assets, including intangible assets, is used to measure recoverability based on the primary asset of the asset group. Some of the more important factors management considers include the Company's financial performance relative to expected and historical performance, significant changes in the way the Company manages its operations, negative events that have occurred, and negative industry and economic trends. If the estimated undiscounted cash flows are less than the carrying amount, measurement of the impairment will be based on the difference between the carrying value and fair value of the asset group, generally determined based on the present value of expected future cash flows associated with the use of the asset. See below for the Company's accounting policy regarding fair value measurements and the definition of fair value levels.
Revenue Recognition and Contract Balances	Revenue Recognition and Contract Balances The Company's revenue is principally from contracts with customers to provide design, development, manufacturing, and support services associated with specific customer programs. The Company regularly enters into long-term master supply agreements that establish general terms and conditions and may define specific program requirements. Many agreements include clauses that provide sole supplier status to the Company for the duration of the program’s life. Purchase orders (or authorizations to proceed) are issued pursuant to the master supply agreements. Additionally, a majority of the Company’s agreements with customers include options for future purchases. Such options primarily reduce the administrative effort of issuing subsequent purchase orders and generally do not represent material rights granted to customers. The Company generally enters into agreements directly with its customers and is the principal in substantially all current contracts. The identification of a contract with a customer for purposes of accounting and financial reporting requires an evaluation of the terms and conditions of agreements to determine whether presently enforceable rights and obligations exist. Management considers a number of factors when making this evaluation that include, but are not limited to, the nature and substance of the business exchange, the specific contractual terms and conditions, the promised products and services, the termination provisions in the contract, as well as the nature and execution of the customer’s ordering process and how the Company is authorized to perform work. Generally, presently enforceable rights and obligations are not created until a purchase order is issued by a customer for a specified number of units of product or services. Therefore, the issuance of a purchase order is generally the point at which a contract is identified for accounting and financial reporting purposes. Management identifies the promises to the customer. Promises are generally explicitly stated in each contract, but management also evaluates whether any promises are implied based on the terms of the agreement, past business practice, or other facts and circumstances. Each promise is evaluated to determine if it is a performance obligation. A performance obligation is a promise in a contract to transfer a distinct good or service. The Company considers a number of factors when determining whether a promise is a distinct performance obligation, including whether the customer can benefit from the good or service on its own or together with other resources that are readily available to the customer, whether the Company provides a significant service of integrating goods or services to deliver a combined output to the customer, or whether the goods or services are highly interdependent. The Company’s performance obligations consist of a wide range of engineering design services and manufactured components, as well as spare parts and repairs for OEMs. The transaction price for a contract reflects the consideration the Company expects to receive for fully satisfying the performance obligations in the contract. Typically, the transaction price consists solely of fixed consideration but may include variable consideration for contractual provisions such as unpriced contract modifications, cost-sharing provisions, and other receipts or payments to customers. The Company identifies and estimates variable consideration, typically at the most likely amount the Company expects to receive from its customers. Variable consideration is only included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized for the contract will not occur, or when the uncertainty associated with the variable consideration is resolved. Consideration paid or payable to a customer is reflected as a reduction in net revenues when the amounts paid are not related to a distinct good or service at the later of when the related revenue is recognized or when the Company pays or promises to pay the consideration to the customer. The Company's contracts with customers generally require payment under normal commercial terms after delivery with payment typically required within 30 to 120 days of delivery. The Company generally is not subject to collecting sales tax and has made an accounting policy election to exclude from the transaction price any sales and other similar taxes collected from customers. As a result, any such collections are accounted for on a net basis. The total transaction price is allocated to each of the identified performance obligations using the relative stand-alone selling price. The objective of the allocation is to reflect the consideration that the Company expects to receive in exchange for the products or services associated with each performance obligation. Stand-alone selling price is the price at which the Company would sell a promised good or service separately to a customer. Stand-alone selling prices are established at contract inception, and subsequent changes in transaction price are allocated on the same basis as at contract inception. When stand-alone selling prices for the Company’s products and services are not observable, the Company uses either the “Expected Cost Plus a Margin” or "Adjusted Market Assessment" approaches to estimate stand-alone selling price. Expected costs are typically derived from the available periodic forecast information. Revenue is recognized when or as control of promised products or services transfers to a customer and is recognized at the amount allocated to each performance obligation associated with the transferred products or services. Service sales, principally representing repair, maintenance, and engineering activities are recognized over the contractual period or as services are rendered. Sales under long-term contracts with performance obligations satisfied over time are recognized using either an input or output method. The Company recognizes revenue over time as it performs on these contracts because of the continuous transfer of control to the customer as represented by contractual terms that entitle the Company to the reimbursement of costs plus a reasonable profit for work performed to manufacture products for which the Company has no alternate use or for work performed on a customer-owned asset. With control transferring over time, revenue is recognized based on the extent of progress toward completion of the performance obligation. The Company generally uses the cost-to-cost input method of progress for its contracts because it best depicts the transfer of control to the customer that occurs as work progresses. Under the cost-to-cost method, the extent of progress toward completion is measured based on the proportion of costs incurred to date to the total estimated costs at completion of the performance obligation. The Company reviews its cost estimates on contracts on a periodic basis, or when circumstances change and warrant a modification to a previous estimate. Cost estimates are largely based on negotiated or estimated purchase contract terms, historical performance trends and other economic projections. Significant factors that influence these estimates include inflationary trends, technical and schedule risk, internal and subcontractor performance trends, business volume assumptions, and asset utilization. Revenue and cost estimates are regularly monitored and revised based on changes in circumstances. Impacts from changes in estimates of net sales and cost of sales are recognized on a cumulative catch-up basis, which recognizes in the current period the cumulative effect of the changes on current and prior periods based on a performance obligation’s percentage of completion. Forward loss reserves for anticipated losses on long-term contracts are recorded in full when such losses become evident, to the extent required and are included in contract liabilities on the accompanying consolidated balance sheets. The Company believes that the accounting estimates and assumptions made by management are appropriate, however actual results could differ materially from those estimates. For the fiscal year ended March 31, 2024, cumulative catch-up adjustments resulting from changes in estimated contract values and contract costs during the fiscal year were immaterial. For the fiscal year ended March 31, 2023, cumulative catch-up adjustments resulting from changes in estimates increased revenue, operating income, income from continuing operations before income taxes, net income, and diluted earnings per share - continuing operations by approximately $ 21,208 , $ 27,963 , $ 27,963 , $ 27,963 , and $ 0.39 , respectively. The cumulative catch-up adjustments to operating income for the fiscal year ended March 31, 2023, included gross favorable adjustments of approximately $ 32,699 and gross unfavorable adjustments of approximately $ 4,736 . For the fiscal year ended March 31, 2022, cumulative catch-up adjustments resulting from changes in estimates increased revenue and operating income and decreased loss from continuing operations before income taxes, net loss and diluted loss per share - continuing operations by approximately $ 6,884 , $ 16,042 , $ 16,042 , $ 16,042 , and $ 0.25 , respectively. The cumulative catch-up adjustments to operating income for the fiscal year ended March 31, 2022, included gross favorable adjustments of approximately $ 30,560 and gross unfavorable adjustments of approximately $ 14,518 . Revenues for performance obligations that are not recognized over time are recognized at the point in time when control transfers to the customer. For performance obligations that are satisfied at a point in time, the Company evaluates the point in time when the customer can direct the use of and obtain the benefits from the products and services. Generally, the shipping terms determine the point in time when control transfers to customers. Shipping and handling activities are not considered performance obligations and related costs are included in cost of sales as incurred. Differences in the timing of revenue recognition and contractual billing and payment terms result in the recognition of contract assets and liabilities. Refer to Note 4 for further discussion.
Warrants	Warrants On December 1, 2022, the Company’s board of directors declared a distribution to holders of the Company’s shares of common stock in the form of warrants to purchase shares of common stock (the “Warrants”). Holders of common stock received three Warrants for every ten shares of common stock held as of December 12, 2022 (the "Record Date"). The Company issued approximately 19.5 million Warrants on December 19, 2022, to holders of record of common stock as of the close of business on the Record Date. Each Warrant represented the right to purchase initially one share of common stock, at an exercise price of $ 12.35 per Warrant, subject to certain anti-dilution adjustments. Payment for shares of common stock on exercise of Warrants could have been made in (i) cash or (ii) under certain circumstances, certain of the Company's outstanding notes (the "Designated Notes"). The common stock warrants were accounted for as derivative liabilities in accordance with ASC 815-40 and included within accrued liabilities on the accompanying consolidated balance sheets. The Company measured the Warrants at fair value as of the issuance date using a Monte Carlo pricing model, a Level 3 fair value measurement (as described below), due to the level of market activity. Inherent in the option pricing simulation are assumptions related to expected stock-price volatility, expected life and risk-free interest rate. The Company estimated the volatility of the Warrants based on implied and historical volatility of the Company’s common stock. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected remaining life of the Warrants. The expected life of the Warrants was based on the Company’s ability to redeem the Warrants, subject to a 20 calendar-day notice period, as well as the automatic acceleration of the Expiration Date following the Price Condition Date. During the three months ended December 31, 2022, due to increased trading volume, the Company began remeasuring outstanding Warrants using the Warrants trading price, a Level 1 fair value measurement (as described below). The Warrants were remeasured at each balance sheet date. Warrants remeasurement adjustments were recognized in warrant remeasurement gain, net on the accompanying consolidated statements of operations. At distribution, the fair value of the Warrants was $ 19,500 . Approximately 7.7 million Warrants were exercised in the year ended March 31, 2024, resulting in total cash proceeds, net of transaction costs, of approximately $ 79,961 , and $ 8,532 of warrants remeasurement gain was recognized in the year ended March 31, 2024. On July 6, 2023, the Company redeemed all of the approximately 11.4 million remaining outstanding Warrants for a total redemption price of approximately $ 11 pursuant to its June 16, 2023, notice of redemption.
Leases	Leases The Company leases office space, manufacturing facilities, land, vehicles, and equipment. The Company determines if an agreement is or contains a lease at the lease inception date and recognizes right-of-use assets (“ROU”) and lease liabilities at the lease commencement date. A ROU asset and corresponding lease liability are not recorded for leases with an initial term of 12 months or less (“short-term leases”). ROU assets represent the Company's right to use an underlying asset during the lease term, and lease liabilities represent the Company's obligation to make lease payments arising from the lease. The determination of the length of lease terms is affected by options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. The existence of significant economic incentive is the primary consideration when assessing whether the Company is reasonably certain of exercising an option in a lease. Both finance and operating lease ROU assets and liabilities are recognized at commencement date and measured as the present value of lease payments to be made over the lease term. As the interest rate implicit in the lease is not readily available for most of the Company's leases, the Company uses its estimated incremental borrowing rate in determining the present value of lease payments. The estimated incremental borrowing rate is derived from information available at the lease commencement date. The lease ROU asset recognized at commencement is adjusted for any lease payments related to initial direct costs, prepayments, and lease incentives. For operating leases, lease expense is recognized on a straight-line basis over the lease term. For finance leases, lease expense comprises the amortization of the ROU assets recognized on a straight-line basis generally over the shorter of the lease term or the estimated useful life of the underlying asset and interest on the lease liability. Variable lease payments not dependent on a rate or index are recognized when the event, activity, or circumstance in the lease agreement upon which those payments are contingent is probable of occurring and are presented in the same line of the consolidated balance sheet as the rent expense arising from fixed payments. The Company has lease agreements with lease and non-lease components. Non-lease components are combined with the related lease components and accounted for as lease components for all classes of underlying assets.
Retirement Benefits	Retirement Benefits Defined benefit pension plans are recognized in the consolidated financial statements on an actuarial basis. A significant element in determining the Company's pension expense (income) is the expected long-term rate of return on plan assets. This expected return is an assumption as to the average rate of earnings expected on the funds invested or to be invested to provide for the benefits included in the projected pension benefit obligation. The Company applies this assumed long-term rate of return to a calculated value of plan assets, which recognizes changes in the fair value of plan assets in a systematic manner over five years. This produces the expected return on plan assets that is included in pension expense (income) . The difference between this expected return and the actual return on plan assets is deferred. The net deferral of past asset gains (losses) affects the calculated value of plan assets and, ultimately, future pension expense (income). The Company periodically experiences events or makes changes to its benefit plans that result in curtailment or special charges. Curtailments are recognized when events occur that significantly reduce the expected years of future service of present employees or eliminates the benefits for a significant number of employees for some or all of their future service. Curtailment losses are recognized when it is probable the curtailment will occur and the effects are reasonably estimable. Curtailment gains are recognized when the related employees are terminated or a plan amendment is adopted, whichever is applicable. From time to time, the Company may enter into transactions that relieve it of primary responsibility for all or more than a minor portion of certain of its pension benefit obligations. When these transactions are effected through an irrevocable action that relieves the Company of primary responsibility for its pension or other postretirement benefit obligations and eliminates significant risks related to the obligation and the related assets used to effect the transaction, they are considered settlements, as defined by ASC 715, Compensation – Retirement Benefits. When a transaction meets the definition of a settlement, at the time of settlement the Company recognizes as a gain or loss the pro rata amount of the net gain or loss in accumulated other comprehensive loss based on the proportion of the projected benefit obligation settled to the total projected benefit obligation. As required under ASC 715, the Company remeasures plan assets and obligations during an interim period whenever a significant event occurs that results in a material change in the net periodic pension cost. The determination of significance is based on judgment and consideration of events and circumstances impacting the pension costs. At March 31 of each year, the Company determines the fair value of its pension plan assets as well as the discount rate to be used to calculate the present value of plan liabilities. The discount rate is an estimate of the interest rate at which the pension benefits could be effectively settled. In estimating the discount rate, the Company looks to rates of return on high-quality, fixed-income investments currently available and expected to be available during the period to maturity of the pension benefits. The Company uses a portfolio of fixed-income securities, which receive at least the second-highest rating given by a recognized ratings agency.
Contingencies	Contingencies Contingencies are existing conditions, situations or circumstances involving uncertainty as to possible gain or loss that will ultimately be resolved when future events occur or fail to occur. Such contingencies include, but are not limited to environmental obligations, litigation, regulatory investigations and proceedings, product quality, and gains or losses resulting from other events and developments. Liabilities for loss contingencies are accrued in the amount of the Company's best estimate for the ultimate loss when a loss is considered probable of having been incurred and is reasonably estimable. When there appears to be a range of possible costs with equal likelihood, liabilities are based on the low-end of such range. Disclosure is provided for material loss contingencies when a loss is probable but a reasonable estimate cannot be made, and when it is reasonably possible that a loss will be incurred or the amount of a loss will exceed the recorded provision. The Company regularly reviews contingencies to determine whether the likelihood of loss has changed and to assess whether a reasonable estimate of the loss or range of loss can be made. Contingencies that might result in gains are generally not accrued until the contingencies are resolved and the gain is realized or realizable. Refer to Note 17 for further disclosure.
Fair Value Measurements	Fair Value Measurements Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. When determining fair value measurements for assets and liabilities required to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and also considers assumptions that market participants would use when pricing an asset or liability. The fair value hierarchy has three levels of inputs that may be used to measure fair value: Level 1—Unadjusted quoted prices in active markets for identical assets or liabilities; Level 2—Unadjusted quoted prices in active markets for similar assets or liabilities, or unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability; and Level 3—Unobservable inputs for the asset or liability. The Company has applied fair value measurements when measuring the warrants (refer to the above disclosure), when disclosing the fair value of its long-term debt not recorded at fair value (see Note 10) and when measuring its pension and postretirement plan assets (see Note 15).
Income Taxes	Income Taxes The Company accounts for income taxes using the asset and liability method. The asset and liability method requires recognition of deferred tax assets and liabilities for expected future tax consequences of temporary differences that currently exist between tax bases and financial reporting bases of the Company's assets and liabilities. A valuation allowance is provided on deferred taxes if it is determined that it is more likely than not that the asset will not be realized. Management judgment is required to determine the amount of benefit to be recognized in relation to an uncertain tax position. The Company uses a two-step process to evaluate tax positions. The first step requires an entity to determine whether it is more likely than not (greater than 50% chance) that the tax position will be sustained. The second step requires an entity to recognize in the financial statements the benefit of a tax position that meets the more-likely-than-not recognition criterion. The amounts ultimately paid upon resolution of issues raised by taxing authorities may differ materially from the amounts accrued and may materially impact the financial statements of the Company in future periods.
