Foreign Currency Exchange Rate Risk

As of March 31, 2014, the Company was party to forward contracts to hedge changes in foreign currency exchange rates with notional amounts of approximately $15.7 million. The Company uses foreign currency forward contracts to mitigate the risk associated with fluctuations in currency rates impacting cash flows related to certain payments for contract manufacturing in its lower-cost manufacturing facilities. The foreign currency forward contracts hedge currency exposure between the Mexican peso and the U.S. dollar and mature at specified monthly settlement dates through January 2015. At inception, the Company designated the foreign currency forward contracts as cash flow hedges.

Interest Rate Risk

In December 2012, the Company entered into an interest rate swap agreement to fix the LIBOR-based variable portion of the interest rates on its term loan A facility. The term loan A swap agreement fixes the LIBOR-based variable portion of the interest rate, beginning February 2013, on a total of $175.0 million notional amount at 0.74% and expires on October 11, 2017. At inception, the Company designated the swap agreement as a cash flow hedge.
