In the six months ended December 31, 2013, there were no triggering events, as defined by FASB ASC 350, which required an interim goodwill impairment test. The Company performs its annual goodwill impairment test in the fourth quarter of each fiscal year. The goodwill adjustment for the Micronetics acquisition is the result of changes in fair value estimates derived from additional information gained during the measurement period which ended August 7, 2013.

The Company determines its reporting units in accordance with FASB ASC 350, by assessing whether discrete financial information is available and if management regularly reviews the operating results of that component. Following this assessment, the Company determined that its reporting units are the same as its operating segments, MCE, MDS and MIS.
