The fair values of acquired intangibles are determined based on an income approach, using estimates and assumptions that are deemed reasonable by the Company. Certain assumptions include the discount rates and other assumptions that form the basis of the forecasted results of the acquired business including revenue, earnings before interest, taxes, depreciation and amortization (“EBITDA”), growth rates, royalty rates and technology obsolescence rates. These assumptions are forward looking and could be affected by future economic and market conditions.

The offset to the measurement period adjustments was to goodwill.

The fiscal 2024 acquisitions of Raptor Scientific, CPI's Electron Device Business, SEI and FPT and fiscal 2023 acquisition of Calspan completed by the Company strengthen and expand the Company’s position to design, produce and supply highly engineered proprietary aerospace components in niche markets with significant aftermarket content and provide opportunities to create value through the application of our three core value-driven operating strategy (obtaining profitable new business, continually improving our cost structure, and providing highly engineered value-added products to customers). The purchase prices paid reflect the current EBITDA As Defined and cash flows, as well as the future EBITDA As Defined and cash flows expected to be generated by the businesses, which are driven in most cases by the recurring aftermarket consumption over the life of a particular aircraft, estimated to be approximately 25 to 30 years. Acquisition transaction-related expenses in fiscal 2024, 2023 and 2022 totaled approximately $33 million, $6 million and $4 million, respectively. These costs are included in selling and administrative expenses in the consolidated statements of income.
