Goodwill

The Company had approximately $3.0 million and $7.4 million of goodwill as of April 1, 2017 and April 2, 2016, respectively. The 2016 balance was associated with the Topwin acquisition and the 2017 balance was associated with the recent acquisition of Visicon (See Note 6 "Business Acquisitions" for further discussion). Purchase accounting was not finalized for the Visicon acquisition as of April 1, 2017. Therefore, the related amounts are provisional and may be revised if additional information regarding the fair value of the associated assets acquired and liabilities assumed as of the acquisition date is identified. Changes in these balances are shown below:

The Company tests goodwill for impairment annually or more frequently if an event occurs or circumstances would indicate that it is more likely than not the fair value of the reporting unit is less than the carrying value. The date of the annual test of goodwill is the first day of the fourth quarter. Accordingly, the Company performed a quantitative test for impairment of the recorded goodwill as of January 1, 2017.

As a result of this test, the estimated fair value of the reporting unit associated with the Topwin acquisition was determined to be less than the carrying value of the reporting unit, indicating a full impairment. This impairment was driven primarily by historical and projected financial performance lower than expectations of the Company and that of comparable companies. The value of the reporting unit was also negatively impacted by a re-evaluation of our product portfolio in connection with announced restructuring plans. This review resulted in the Company prioritizing away from some of the lower-cost systems that were planned for manufacturing at Topwin, impacting the value of the reporting unit.

The Company performed a qualitative test of goodwill associated with the Visicon acquisition and, in part due to the proximity to the acquisition date and the fact that purchase accounting is not yet finalized, the Company determined it is more likely than not the fair value is greater than the carrying value, indicating no impairment.

The fair value of the goodwill was determined using generally accepted valuation approaches. These approaches included a discounted cash flow model, a guideline transaction approach, and a guideline public company market multiples approach, each weighted according to the relevance of each approach. In supporting these valuations, management used assumptions based on the best information available. The loss from impairment of goodwill was recorded as a component of operating expenses in a separate line on the Consolidated Statements of Operations.
