Business Acquisition, Description of Acquired Entity

In May 2015, the Company entered into a share purchase agreement with the shareholders of DXI Limited for a purchase price of $22.5 million, consisting of $18.7 million in cash paid to the DXI shareholders at closing and $3.8 million in cash deposited into escrow to be held for two years as security against indemnity claims made by the Company after the closing date. During the fiscal quarter ended June 30, 2017, $1.4 million of the cash held in escrow was returned to the Company and the escrow fund was closed. Since the purchase accounting for the acquisition was finalized by March 31, 2016, the proceeds are realized as a gain and reported as other income in the consolidated statements of operations.

Goodwill, Impaired, Facts and Circumstances Leading to Impairment    

The Company performs its annual goodwill impairment test on January 1 of each year and during the year, whenever a triggering event for such an assessment is identified. During the third quarter of fiscal year 2018, the Company changed its product and marketing strategy for the use of DXI's technology and re-assessed the profitability outlook which triggered the requirement that the Company test the recorded goodwill for impairment in accordance with ASC 350-20-35, as amended by ASU 2017-04 (see Footnote 1, Recently Adopted Accounting Pronouncements). First, the Company estimated the fair value of its three reporting units using the market approach. Under the market approach, the Company utilized the market capitalization of its publicly-traded shares and comparable company information to determine revenue multiples which were used to determine the fair value of the reporting unit. Based on this approach, the Company determined that there was an indication of impairment for its DXI reporting unit in the UK as the carrying value including goodwill exceeded the estimated fair value. As largely independent cash flows could not be attributed to any assets individually the Company evaluated DXI's assets and liabilities as one asset group. Then the Company estimated the fair value of DXI's assets and liabilities as one asset group using discounted cash flow methods to determine the implied fair value of goodwill. The difference between this implied fair value of the goodwill and its carrying value was recorded as impairment. The outcome of the analysis resulted in a non-cash expense for impairment of property and equipment, intangible assets and goodwill of $0.3 million, $1.2 million and $8.0 million, respectively, which was recorded during the third quarter of fiscal year 2018 as a separate line item in the Company's Condensed Consolidated Statements of Operations.

These assets are reported within the Company's Europe (primarily UK) reporting segment (Footnote 9). The inputs used to measure the estimated fair value of goodwill are classified as a Level 3 fair value measurement due to the significance of unobservable inputs based on company specific information.
