Derivative Instruments

The Company has international operations and is thus subject to foreign currency rate fluctuations.  To help manage the risk of changes in foreign currency rates, the Company periodically enters into derivative contracts comprised of foreign currency forward contracts to hedge its asset and liability foreign currency exposure and a portion of its foreign currency operating expenses.  Approximately 99% of the Company's sales are U.S. dollar denominated.  To date, the exposure related to foreign exchange rate volatility has not been material to the Company's operating results.  As of September 30, 2014 and March 31, 2014, the Company had no foreign currency forward contracts outstanding. The Company recognized an immaterial amount of net realized gains and losses on foreign currency forward contracts in each of the three and six months ended September 30, 2014 and 2013. Gains and losses from changes in the fair value of these foreign currency forward contracts are credited or charged to Other Income (Expense). The Company does not apply hedge accounting to its foreign currency derivative instruments.
