Foreign Currency Exchange Rate Risk

As of March 31, 2015, the Company was party to forward contracts to hedge changes in foreign currency exchange rates with notional amounts of approximately $16.5 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, the Thai baht and the Australian dollar and the U.S. dollar and the Australian dollar and mature at specified monthly settlement dates through March 2016. 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.

The following tables summarize the income (loss) recognized in accumulated other comprehensive income ("AOCI"), the amounts reclassified from AOCI into earnings and the amounts recognized directly into earnings for the three months ended March 31, 2015 and 2014:

	Amount of Income (Loss) Recognized in AOCI on Derivative (Effective Portion, net of tax)						Amount of Income (Loss) Reclassified from AOCI into Earnings
							Three months ended March 31,
	As of March 31, 2015		As of December 31, 2014			Location of Income (Loss) Reclassified from AOCI into Earnings (Effective Portion)	2015			2014

Over the next 12 months, the Company expects to reclassify approximately $0.6 million of pre-tax deferred losses from AOCI to interest expense as the related interest payments for the designated interest rate swap are funded and approximately $0.1 million of pre-tax deferred gains from AOCI to cost of sales as the intercompany inventory purchases are settled.

Fair Value Measurements

The fair value of the Company's derivatives are estimated using an income approach based on valuation techniques to convert future amounts to a single, discounted amount. Estimates of the fair value of the Company's interest rate swap and foreign currency forward contracts use observable inputs such as interest rate yield curves and forward currency exchange rates. Fair value measurements and the fair value hierarchy level for the Company's assets and liabilities measured at fair value on a recurring basis as of March 31, 2015 and December 31, 2014 are shown below.
