10. Financial Instruments

The carrying amounts of financial instruments, including cash and cash equivalents, accounts receivable and accounts payable approximated their fair value as of September 30, 2013 and December 31, 2012, because of the relative short maturity of these instruments.

“Fair Value Measurements and Disclosures” defines fair value as the price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

The accounting standard establishes a fair value hierarchy that prioritizes the inputs used to measure fair value into three levels. The three levels are defined as follows:

⋅ Level 1: Unadjusted quoted price in active market for identical assets and liabilities.

⋅ Level 2: Observable inputs other than those included in Level 1.

⋅ Level 3: Unobservable inputs reflecting management’s own assumptions about the inputs used in pricing the asset or liability.

The following table sets forth the assets and liabilities as of September 30, 2013 and December 31, 2012 that the Company measured at fair value, on a recurring basis by level, within the fair value hierarchy (in thousands). As required by the standard, assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to their fair value measurement.

The Level 2 assets and liabilities contain foreign currency forward contracts. Fair value is determined based on the observable market transactions of spot and forward rates. The fair value of these contracts as of September 30, 2013 is included in accrued expenses and December 31, 2012 is included in prepaid expenses and other current assets in the accompanying condensed consolidated balance sheets.

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 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. The fixed assets were measured at fair value on a nonrecurring basis using significant unobservable inputs (Level 3).
