Derivative Financial Instruments

Foreign Currency Exchange Rate Risk

The Company enters into foreign currency forward contracts not formally designated as hedges to manage the consolidated exchange rate risk associated with the remeasurement of non-functional currency denominated monetary assets and liabilities. Changes in fair value of foreign currency forward contracts are recognized in income at the end of each reporting period based on the difference between the contract rate and the spot rate. In general, these gains and losses are offset in the Consolidated Statements of Income by the reciprocal gains and losses from the underlying assets or liabilities which originally gave rise to the exposure. The net amount of the gains and losses related to derivative instruments recorded in other income, net for the three and six months ended June 30, 2018 were net losses of $4.0 million and $8.6 million, respectively. The net losses for the three and six months ended June 30, 2017 were $6.5 million and $7.5 million, respectively.
