The Company, when it considers it to be appropriate, enters into forward contracts to hedge the economic exposures arising from foreign currency denominated transactions. At June 30, 2019 and December 31, 2018, these contracts included the future sale of Japanese Yen to purchase U.S. dollars. Derivative instruments are measured at fair value and recognized as either, “Prepaid expenses and other current assets” or “Other current liabilities” in the Condensed Consolidated Balance Sheets with changes in the net derivatives position reflected in operating cash flows. The foreign currency forward contracts were entered into by the Company’s Japanese subsidiary to economically hedge a portion of certain intercompany obligations. The forward contracts are not designated as hedges for accounting purposes and decreases in the fair value of $6 and $55 for the six months ended June 30, 2019 and 2018, respectively, are recorded under the caption “Other expense (income), net” in the Condensed Consolidated Statements of Operations.
