As of September 30, 2022 and March 31, 2022, approximately $21.0 million and $21.4 million of goodwill in the government systems segment was reclassified to discontinued operations, respectively. See Note 4 — Discontinued Operations— for more information on discontinued operations. During the six months ended September 30, 2021, the increase in the Company’s goodwill related to the acquisitions of the remaining 51% interest in EBI and of RigNet on April 30, 2021 (see Note 5 – Acquisitions for more information) and an insignificant effect of foreign currency translation recorded within all three of the Company’s segments. Other acquired intangible assets are amortized using the straight-line method over their estimated useful lives of two to 20 years (which approximates the economic pattern of benefit). Amortization expense related to other acquired intangible assets was $7.4 million for both the three months ended September 30, 2022 and 2021, and $14.9 million and $13.3 million for the six months ended September 30, 2022 and 2021, respectively.
