Commitments And Contingencies [Abstract]
Commitments and Contingencies	12. 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 July 2024, a panel of three arbitrators made a decision in an arbitration between Triumph Aerostructures, LLC (“TAS”), a wholly owned subsidiary of the Company, and Northrop Grumman Systems Corporation (“Northrop”) related to responsibility for environmental remediation costs at certain formerly occupied properties that had been previously operated by Northrop. The decision indicated that TAS would be liable to reimburse Northrop for remediation costs incurred at the properties through September 2023 in the amount of approximately $11,500. The decision also indicated that TAS would be responsible for reimbursing Northrop for remediation costs at two of the facilities incurred subsequent to September 2023. Such incremental remediation costs for the period from September 2023 to June 30, 2024 are estimated to be approximately $2,000. Accordingly, TAS has accrued a total of approximately $13,464 following the decision, of which $7,464 was recognized in the three months ended June 30, 2024, and is presented within legal contingencies loss on the Company’s condensed consolidated statement of operations. The Company estimates that total future remediation costs reimbursable to Northrop could be up to approximately $38,000, and result in annual cash expenditures not likely to exceed $2,000 to $3,000 per year. In addition, TAS is a party to the environmental remediation regulatory order at one of the properties. Therefore, in accordance with ASC 410-30, Environmental obligations, the Company has accrued approximately $1,300 as management's best estimate of the total future remediation costs at this property. TAS intends to continue to vigorously defend itself in this matter, including potentially seeking to set aside the adverse decision from the arbitration panel. Commercial Disputes and Litigation Throughout the course of the Company’s programs, disputes with suppliers or customers have arisen and could arise in the future 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 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 commercial dispute, 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 June 30, 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 June 30, 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 divestiture related 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 this matter will have a material effect 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 guarantor 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 typically has a right to indemnification from acquirers against such losses that may arise from the acquirers’ failure to perform under the assigned contracts. On June 13, 2024, Boeing submitted correspondence to the Company asserting that under the terms of a guarantee agreement between Boeing and the Company (the “Guarantee Agreement”), the Company would be responsible for damages that Boeing may suffer should Qarbon Aerospace, LLC (“Qarbon”), the acquirer of the Company’s Red Oak facility, cease performance on the T7-A program, which is the subject of ongoing litigation between the Company and Qarbon. Boeing did not provide details regarding its contractual dispute with Qarbon or allege any damages incurred. As of June 30, 2024, no related indemnification assets or liabilities or guarantee liabilities have been recorded. The Company intends to vigorously defend itself against any assertion that Boeing is entitled to damages from the Company under the Guarantee Agreement, but the Company has concluded that a loss is reasonably possible. At this time, based on the early stage of this matter, the Company is unable to reasonably estimate the amount of any damages that Boeing has incurred or may claim. Separately, pursuant to the terms of the purchase agreement providing for Qarbon’s acquisition of the Red Oak facility, the Company is entitled to indemnification from Qarbon. Also, in connection with certain divestitures, the Company has assigned lease facility agreements to the acquirers and entered into guarantee agreements with respect to the lease agreement in the event of non-performance under the lease by the assignee. The Company typically has a right to indemnification from 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 may be barred from recovery due to its acceptance of the lessee's surrender of the premises. The Company currently estimates that a reasonably possible loss, if any, would be recoverable through indemnification and be immaterial. 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. As of June 30, 2024, the Company's liability for this obligation is included on the accompanying condensed consolidated balance sheet is approximately $13,502, representing its estimate of the remaining obligation before interest based on the letter received from the Fund. The Company has issued a formal challenge through arbitration on the issue of the interest rate used by the Fund when determining the Withdrawal Liability, and it is possible the Withdrawal Liability could be reduced during that process.

12. 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 July 2024, a panel of three arbitrators made a decision in an arbitration between Triumph Aerostructures, LLC (“TAS”), a wholly owned subsidiary of the Company, and Northrop Grumman Systems Corporation (“Northrop”) related to responsibility for environmental remediation costs at certain formerly occupied properties that had been previously operated by Northrop. The decision indicated that TAS would be liable to reimburse Northrop for remediation costs incurred at the properties through September 2023 in the amount of approximately $11,500. The decision also indicated that TAS would be responsible for reimbursing Northrop for remediation costs at two of the facilities incurred subsequent to September 2023. Such incremental remediation costs for the period from September 2023 to June 30, 2024 are estimated to be approximately $2,000. Accordingly, TAS has accrued a total of approximately $13,464 following the decision, of which $7,464 was recognized in the three months ended June 30, 2024, and is presented within legal contingencies loss on the Company’s condensed consolidated statement of operations. The Company estimates that total future remediation costs reimbursable to Northrop could be up to approximately $38,000, and result in annual cash expenditures not likely to exceed $2,000 to $3,000 per year. In addition, TAS is a party to the environmental remediation regulatory order at one of the properties. Therefore, in accordance with ASC 410-30, Environmental obligations, the Company has accrued approximately $1,300 as management's best estimate of the total future remediation costs at this property. TAS intends to continue to vigorously defend itself in this matter, including potentially seeking to set aside the adverse decision from the arbitration panel.

Commercial Disputes and Litigation

Throughout the course of the Company’s programs, disputes with suppliers or customers have arisen and could arise in the future 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 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 commercial dispute, 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 June 30, 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 June 30, 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 divestiture related 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 this matter will have a material effect 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 guarantor 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 typically has a right to indemnification from acquirers against such losses that may arise from the acquirers’ failure to perform under the assigned contracts. On June 13, 2024, Boeing submitted correspondence to the Company asserting that under the terms of a guarantee agreement between Boeing and the Company (the “Guarantee Agreement”), the Company would be responsible for damages that Boeing may suffer should Qarbon Aerospace, LLC (“Qarbon”), the acquirer of the Company’s Red Oak facility, cease performance on the T7-A program, which is the subject of ongoing litigation between the Company and Qarbon. Boeing did not provide details regarding its contractual dispute with Qarbon or allege any damages incurred. As of June 30, 2024, no related indemnification assets or liabilities or guarantee liabilities have been recorded. The Company intends to vigorously defend itself against any assertion that Boeing is entitled to damages from the Company under the Guarantee Agreement, but the Company has concluded that a loss is reasonably possible. At this time, based on the early stage of this matter, the Company is unable to reasonably estimate the amount of any damages that Boeing has incurred or may claim. Separately, pursuant to the terms of the purchase agreement providing for Qarbon’s acquisition of the Red Oak facility, the Company is entitled to indemnification from Qarbon.

Also, in connection with certain divestitures, the Company has assigned lease facility agreements to the acquirers and entered into guarantee agreements with respect to the lease agreement in the event of non-performance under the lease by the assignee. The Company typically has a right to indemnification from 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 may be barred from recovery due to its acceptance of the lessee's surrender of the premises. The Company currently estimates that a reasonably possible loss, if any, would be recoverable through indemnification and be immaterial.

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. As of June 30, 2024, the Company's liability for this obligation is included on the accompanying condensed consolidated balance sheet is approximately $13,502, representing its estimate of the remaining obligation before interest based on the letter received from the Fund. The Company has issued a formal challenge through arbitration on the issue of the interest rate used by the Fund when determining the Withdrawal Liability, and it is possible the Withdrawal Liability could be reduced during that process.
