Derivative Instruments

5. Derivative Instruments

We are exposed to foreign currency exchange rates related to our business operations. To reduce our risks related to these exposures, we utilize certain derivative instruments, namely foreign currency forward contracts. We do not use derivatives for speculative trading purposes.

We enter into foreign currency forward contracts, none of which are designated as hedging transactions for accounting purposes, to reduce our exposure to foreign currency fluctuations of certain liabilities denominated in foreign currencies. These exposures are hedged on a quarterly basis. We held no foreign currency forward contracts at December 31, 2014.  As of December 31, 2013, we had foreign currency forward contracts with notional amounts of €7.7 million ($10.6 million based on the exchange rate as of December 31, 2013). As of December 31, 2013, we recorded a derivative asset within prepaid expenses and other current assets of $372,000 related to these foreign currency forward contracts.  

For the years ended December 31, 2014 and 2013, we recorded an unrealized loss of $114,000 and an unrealized gain of $261,000 , respectively, in interest and other income, net on our consolidated statement of operations related to these foreign currency forward contracts. During the year ended December 31, 2014, we settled foreign currency forward contracts and recognized a realized loss of $258,000 in interest and other income (expense), net. During the year ended December 31, 2013, we settled foreign currency forward contracts and recognized a realized gain of $60,000 in interest and other income (expense), net.

Our derivative financial instruments present certain market and counterparty risks. In general, the market risk related to these contracts is offset by corresponding gains and losses on the hedged transactions. The credit risk associated with these contracts is driven by changes in interest and currency exchange rates and, as a result, varies over time.
