11. Derivative Instruments and Hedging Activities

Interest Rate Risks

The Company’s exposure to interest rate risk relates primarily to outstanding variable rate debt and adverse movements in the related short-term market rates. Typically, the most significant component of the Company’s interest rate risk relates to amounts outstanding under the 2015 Credit Agreement, which totaled $124.8 million at March 31, 2019. The Company currently has a higher level of fixed rate debt than variable rate debt, which limits the exposure to adverse movements in interest rates.

Foreign Exchange Rate Risk Management

The Company generates a substantial portion of its revenues and expenses in international markets which subjects its operations to the exposure of exchange rate fluctuations. The impact of currency exchange rate movement can be positive or negative in any period. The Company periodically enters into foreign currency contracts in order to minimize the volatility that fluctuations in currency translation have on its monetary transactions. Under these arrangements, the Company typically agrees to purchase a fixed amount of a foreign currency in exchange for a fixed amount of U.S. Dollars or other currencies on specified dates with maturities of less than twelve months, with some agreements extending to longer periods. The Company had the following notional amounts outstanding under foreign exchange contracts at March 31, 2019 and December 31, 2018 (in millions):

In addition, the Company periodically enters into purchase and sales contracts denominated in currencies other than the functional currency of the parties to the transaction. The Company accounts for these transactions separately valuing the “embedded derivative” component of these contracts. The contracts, denominated in currencies other than the functional currency of the transacting parties, amounted to $99.3 million for the delivery of products and $6.3 million for the purchase of products at March 31, 2019 and $113.5 million for the delivery of products and $6.0 million for the purchase of products at December 31, 2018. The changes in the fair value of these embedded derivatives are recorded in interest and other income (expense), net in the consolidated statements of income and comprehensive income.

Commodity Price Risk Management

The Company has arrangements with certain customers under which it has a firm commitment to deliver copper based superconductor wire at a fixed price. In order to minimize the volatility that fluctuations in the price of copper have on the Company’s sales of these commodities, the Company enters into commodity hedge contracts. At March 31, 2019 and December 31, 2018, the Company had fixed price commodity contracts with notional amounts aggregating $5.1 million and $6.8 million, respectively. The changes in the fair value of these commodity contracts are recorded within interest and other income (expense), net in the unaudited condensed consolidated statements of income and comprehensive income.

The fair value of the derivative instruments described above is recorded in the unaudited condensed consolidated balance sheets for the periods as follows (dollars in millions):


		March 31,		December 31,
	Balance Sheet Location	2019		2018
