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. As of September30, 2013 and December31, 2012, we had foreign currency forward contracts with notional amounts of €9.5million ($12.9 million based on the exchange rate as of September30, 2013) and €16.8million ($22.2 million based on the exchange rate as of December31, 2012), respectively, that were not designated as hedges. As of September30, 2013, we recorded a derivative asset within prepaid expenses and other current assets and other long term assets of $239,000 and $27,000, respectively, related to these foreign currency forward contracts. As of December31, 2012, we recorded a derivative asset within prepaid expenses and other current assets and other long-term assets of $30,000 and $21,000, respectively, related to these foreign currency forward contracts.

We recorded an unrealized gain of $450,000 and an unrealized gain of $97,000 in interest and other income (expense), net on our condensed statements of operations related to these foreign currency forward contracts for the three and nine months ended September30, 2013, respectively. During the three and nine months ended September 30, 2013, the Company settled foreign currency forward contracts and recognized a realized gain of $45,000 and $118,000, respectively, in interest and other income (expense), net. During the three and nine months ended September 30, 2012 we recognized an unrealized gain of $243,000 and an unrealized loss of $450,000, respectively, andno realized gains or losses.

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.
