Intangible Assets Impairmrent Of Long-lived Assets Narrative Details |
Impaired Intangible Asset, Description | 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 DXI's profitability outlook. This 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 only 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 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 Consolidated Statements of Operations.
