Intangibles

We complete our annual impairment tests in the fourth quarter of each year unless events or circumstances indicate that an asset may be impaired. The Company recorded an intangible asset impairment charge for the year ended March 31, 2014 of $154 to write down trade names pursuant to its decision to rename and rebrand the subsidiaries under DT USA to DT EMEA and DT APAC. There were no other indications of impairment present during the periods ended June 30, 2014 and March 31, 2014. In the period ended June 30, 2014, we finalized the purchase price allocation of DT APAC, which resulted in an adjustment to intangibles of $1,472.
