Goodwill and Intangible Assets Disclosure [Abstract] |
Goodwill and Acquired Intangible Assets | Note 5 — Goodwill and Acquired Intangible Assets During each of the six months ended September 30, 2025 and 2024, the insignificant increase in the Company’s goodwill was primarily related to foreign currency translation effect, mainly in the Company's communication services segment. 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 acquired intangible assets was $65.1 million and $66.0 million for the three months ended September 30, 2025 and 2024, respectively, and $130.8 million and $132.2 million for the six months ended September 30, 2025 and 2024, respectively. Goodwill by segments as of September 30, 2025 and March 31, 2025 was as follows:
|  | As of September 30, 2025 |  |  | As of March 31, 2025 |
