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.
