Goodwill and Intangible Assets Disclosure [Abstract] |
Goodwill | Goodwill The changes in the carrying value of goodwill were as follows (in thousands):
|  | Amount
Balance as of December 31, 2013 and 2014 |  | $ | 77,388 |
Business acquisition (Note 20) |  | 4,060 |
Balance as of December 31, 2015 |  | $ | 81,448 |
On July 6, 2015, the Company completed the sale of its Surface Inspection Systems Division (SISD). Goodwill assigned to SISD was $4,301,000 and has been included as part of the sale. The Company had previously identified SISD, along with its Modular Vision Systems Division (MVSD), as reporting units for purposes of its goodwill impairment test. Given the disposition of SISD, management reviewed its reporting units and concluded that the Company now has one reporting unit. For its 2015 analysis of goodwill, management elected to perform a qualitative assessment (commonly known as “step zero”). Based upon this assessment, management does not believe that it is more likely than not that the carrying value of the reporting unit exceeds its fair value. Factors that management considered in the qualitative assessment include macroeconomic conditions, industry and market considerations, overall financial performance (both current and projected), changes in management or strategy, and changes in the composition or carrying amount of net assets. In addition, management took into consideration the goodwill valuation as of October 4, 2010, which was the last time it was performed under the two-step process. At that time, this analysis indicated that the fair value of the MVSD reporting unit exceeded its carrying value by approximately 208%. As of December 31, 2015, management does not believe any qualitative factors exist that would change the conclusion of their assessment.
