The additions to goodwill during the three months ended June 30, 2017 were due to the Merger described in Note 3 - "Acquisitions." As a result of the Merger, the Company began to report the United States Public Sector ("USPS") segment, formerly a component of the HPES business, see Note 17 - "Segment Information" for additional information. The foreign currency translation amounts reflect the impact of currency movements on non-U.S. dollar-denominated goodwill balances.

Goodwill Impairment Analyses

The Company tests goodwill for impairment on an annual basis, as of the first day of the second fiscal quarter, and between annual tests if circumstances change, or if an event occurs that would more likely than not reduce the fair value of a reporting unit below its carrying amount. As of June 30, 2017, the Company assessed whether there were events or changes in circumstances that would more likely than not reduce the fair value of any of its reporting units below its carrying amount and require goodwill to be tested for impairment. The Company determined that there have been no such indicators and therefore, it was unnecessary to perform an interim goodwill impairment test as of June 30, 2017.
