DERIVATIVE INSTRUMENTS

Freestanding Derivative Forward Contracts

Foreign Currency Exchange Rate Risk

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.  Net losses due to foreign exchange rate fluctuations after the effects of hedging activity were $7.7 million during fiscal 2015, compared to net gains of $0.4 million during fiscal 2014 and net losses of $2.8 million during fiscal 2013. As of March 31, 2015 and 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 the years ended March 31, 2015, 2014 and 2013. Gains and losses from changes in the fair value of these foreign currency forward contracts and foreign currency exchange rate fluctuations are credited or charged to Other Income (Expense). The Company does not apply hedge accounting to its foreign currency derivative instruments.

Fair Value Hedges

For derivative instruments that are designated and qualify as fair value hedges, the gain or loss on the derivatives as well as the offsetting gain or loss on the hedged item attributable to the hedged risk are recognized in earnings. Interest rate derivative instruments designated as fair value hedges are designed to manage the exposure to interest rate movements and to reduce borrowing costs by converting fixed-rate debt into floating-rate debt. Under these agreements, the Company agrees to exchange, at specified intervals, the difference between the fixed and floating interest amounts calculated by reference to an agreed-upon notional principal amount.

In March 2015, the Company entered into ten-year fixed-to-floating interest rate swap agreements designated as fair value hedges of the changes in fair value of a portion of the Company's fixed-rate 1.625% senior subordinated convertible debentures due to changes in the LIBOR swap rate, the designated benchmark interest rate. The Company pays variable interest equal to the three-month LIBOR minus 53.6 basis points and it receives a fixed interest rate of 1.625%. The notional amount of these contracts outstanding at March 31, 2015 was $431.3 million, representing 25% of the principal amount of the senior subordinated convertible debentures.
