Acquisition and Related Goodwill | Acquisition and Related Goodwill Acquisition of Infinia Technology Corporation On September 25, 2017, the Company acquired Infinia Technology Corporation ("ITC") for approximately $3.8 million (the "Acquisition"). Located in Richmond, Washington, ITC is a technology firm founded in 2009 specializing in the design, development and commercialization of cryo-coolers for a wide range of applications. This technology supports the Company's efforts with the U.S. Navy and Ship Protection Systems (“SPS”) products. The results of ITC's operations, which were not significant from the date of acquisition through December 31, 2018, are included in the Company’s consolidated results from the date of Acquisition of September 25, 2017, through December 31, 2018. Assuming the Acquisition had occurred on April 1, 2017, the impact on the consolidated results of the Company would not have been significant. Goodwill At the time of the Acquisition, the Company allocated the purchase price to the assets acquired and liabilities assumed at their estimated fair values as of the date of Acquisition. The excess of the purchase price paid by the Company over the estimated fair value of net assets acquired of $1.7 million has been recorded as goodwill in the Company's Grid segment. Goodwill represents the value associated with the acquired workforce and synergies related to the merger of the two companies. The Company did not identify any triggering events in the nine months ended December 31, 2018, that would require interim impairment testing of goodwill.
