The Synodex subsidiary of the IADS segment has not achieved significant revenue to date and has incurred losses since inception. As a result in the third quarter of 2013, the Company evaluated the carrying value of the fixed assets of its Synodex subsidiary compared to its fair value and concluded that that the carrying value exceeds its fair value. This resulted in an impairment charge of $5.5 million for the three and nine months ended September 30, 2013.
