Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

Our market risk consists primarily of foreign currency exchange risk and interest rate risk. Our functional currency is the U.S. dollar and our primary manufacturing operations and inventory supply contracts are in the U.S., but we distribute our products worldwide both through direct export and through our foreign subsidiaries. Our primary foreign currency transaction risk consists of intercompany purchases and sales of products and we attempt to mitigate this risk through our hedging program described below. Approximately 28% of our consolidated revenue for the year ended December 31, 2014 and 26% of our consolidated revenue for each of the years ended December 31, 2013 and 2012 was derived from products manufactured in the U.S. and sold internationally in local currencies. The functional currency of most of our subsidiaries is their local currency. For two of our subsidiaries located in the Netherlands and Singapore, the functional currency is the U.S. dollar.

The primary purpose of our foreign currency hedging activities is to protect against the volatility associated with foreign currency transactions. We also utilize natural hedges to mitigate our transaction and commitment exposures. Our corporate policy prescribes the range of allowable hedging activity. We enter into foreign currency exchange contracts with large multinational financial institutions and we do not hold or engage in transactions involving derivative instruments for purposes other than risk management. Our accounting policies for these contracts are based on our designation of such instruments as hedging transactions. If a derivative instrument qualifies for hedge accounting, changes in the fair value of the derivative instrument from the effective portion of the hedge are deferred in accumulated other comprehensive income, net of tax, and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. We immediately record in earnings the extent to which a hedge instrument is not effective in achieving offsetting changes in fair value. We primarily utilize foreign currency exchange contracts with durations of less than 24 months.

Our subsidiaries enter into foreign currency exchange contracts to manage the exchange risk associated with their forecasted intercompany inventory purchases and sales for the next year. From time to time, we may also enter into foreign currency exchange contracts to minimize the impact of foreign currency fluctuations associated with specific, significant transactions. As of December 31, 2014 and 2013, we were not hedging any specific, significant transactions.

Our foreign currency hedging strategy is consistent with prior periods and there were no material changes in our market risk exposure during the year ended December 31, 2014. We enter into foreign currency exchange contracts designated as cash flow hedges for amounts that are less than the full value of forecasted intercompany purchases and sales and for amounts that are equivalent to, or less than, other significant transactions. As a result, no significant ineffectiveness has resulted or been recorded through the statements of operations for the years ended December 31, 2014, 2013 and 2012. Our hedging strategy related to intercompany inventory purchases and sales is to employ the full amount of our hedges for the succeeding year at the conclusion of our budgeting process for that year. Quarterly, we enter into contracts to hedge incremental portions of anticipated foreign currency transactions for the current and following year. Accordingly, our risk with respect to foreign currency exchange rate fluctuations may vary throughout each annual cycle.

We enter into hedge agreements where we believe we have meaningful exposure to foreign currency exchange risk. The notional amount of foreign currency exchange contracts to hedge forecasted intercompany purchases and sales totaled $186.7 million and $168.3 million at December 31, 2014 and December 31, 2013, respectively. At December 31, 2014, we had $8.1 million of net unrealized gains on foreign currency exchange contracts recorded in accumulated other comprehensive income, net of tax expense.

Our foreign currency exchange risk is comprised of three components: 1) local currency revenues and expenses; 2) the impact of settled hedge contracts; and 3) intercompany and monetary balances for our subsidiaries that are denominated in a currency that is different from the functional currency used by each subsidiary. Based on projected revenues and expenses for 2015, excluding the impact of intercompany and trade balances denominated in currencies other than the functional subsidiary currencies, a 10% strengthening of the U.S. dollar would reduce operating income by approximately $9 million. The impact of the intercompany and monetary balances referred to in the third component above have been excluded, as they are transacted at multiple times during the year and we are not able to reliably forecast the impact that changes in exchange rates would have.

In June 2014, we refinanced our existing $450.0 million unsecured revolving credit facility by entering into an amended and restated credit agreement relating to a five-year unsecured revolving credit facility in the principal amount of $700 million with a syndicate of multinational banks, which matures on June 18, 2019. We are subject to interest rate risk based on the terms of the Credit Facility to the extent that the London interbank rate (“LIBOR”) or the Canadian Dollar-denominated bankers’ acceptance rate (“CDOR”) increases. Borrowings under the Credit Facility bear interest in the range from 0.875 to 1.375 percentage points (“Credit Spread”) above the LIBOR or the CDOR, dependent on our consolidated leverage ratio, and the interest period terms for the outstanding borrowings, which range from one to six months. As discussed below, we have entered into forward fixed interest rate swaps to mitigate a portion of our interest rate risk in future periods. Borrowings outstanding under the Credit Facility at December 31, 2014 were $549 million at a weighted-average effective interest rate of 1.5%. Based on amounts outstanding and our interest rate swap effective at December 31, 2014, an increase in the LIBOR or the CDOR of 1% would increase interest expense by approximately $4.7 million on an annualized basis.

Beginning on March 30, 2012, the variable interest rate associated with $40 million of borrowings outstanding under the Credit Facility became effectively fixed at 1.36% plus the Credit Spread through June 30, 2016. Beginning on March 28, 2013, the variable interest rate associated with an additional $40 million of borrowings outstanding under the Credit Facility became effectively fixed at 1.64% plus the Credit Spread through June 30, 2016. We have designated these swaps as qualifying instruments to be accounted for as cash flow hedges. At December 31, 2014, we had $0.7 million in unrealized losses, net of income tax benefit, on interest rate swaps designated as hedging instruments. See Note 16 to the consolidated financial statements included in this Annual Report on Form 10-K for a discussion of our derivative instruments and hedging activities.
