Goodwill and Acquired Intangible Assets

Note 5 — Goodwill and Acquired Intangible Assets

During the first six months of fiscal year 2017, the Company’s goodwill decreased by $0.6 million, which related to the effects of foreign currency translation recorded within the Company’s government systems and commercial networks segments.

Other acquired intangible assets are amortized using the straight-line method over their estimated useful lives of two to ten years. Amortization expense related to other acquired intangible assets was $2.3 million and $4.6 million for the three months ended September 30, 2016 and 2015, respectively, and $4.8 million and $9.4 million for the six months ended September 30, 2016 and 2015, respectively.

The expected amortization expense of amortizable acquired intangible assets may change due to the effects of foreign currency fluctuations as a result of international businesses acquired. Current and expected amortization expense for acquired intangible assets for each of the following periods is as follows:
