Goodwill and Acquired Intangible Assets

Note 6 — Goodwill and Acquired Intangible Assets

During fiscal year 2025, the Company’s goodwill remained flat. During fiscal year 2024, the increase in the Company’s goodwill was primarily related to the Inmarsat Acquisition (see Note 4 — Acquisition for more information) and foreign currency translation effects recorded within both of the Company's segments.

Other acquired intangible assets are amortized using the straight-line method over their estimated useful lives of two to 12 years (which approximates the economic pattern of benefit). Amortization expense related to other acquired intangible assets was $263.9 million, $227.2 million and $29.8 million for fiscal years 2025, 2024 and 2023, respectively.

Other acquired intangible assets and the related accumulated amortization as of March 31, 2025 and 2024 were as follows:
