We may enter into foreign exchange forward contracts to hedge against the effect of exchange rate fluctuations on cash flows denominated in foreign currencies associated with our subsidiary in Singapore. These transactions are designated as cash flow hedges and are recorded in the accompanying consolidated balance sheets at fair value. The effective portion of the gain or loss on these derivatives is reported as a component of other comprehensive income (loss) and reclassified into earnings in the same period during which the hedged transaction affects earnings. Gains and losses on the derivatives representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings. The maximum length of time over which we hedge our exposure to the variability in future cash flows is 12 months.

There were no open cash flow hedges at December 31, 2016 or at any time during the nine months ended September 30, 2017. In the nine months ended September 30, 2016, hedge ineffectiveness and the amounts excluded from effectiveness testing recognized in earnings on cash flow hedges were not material.

Reclassifications of amounts from accumulated other comprehensive income (loss) into earnings for cash flow hedges include accumulated gains (losses) at the time earnings were impacted by the hedged transaction. The location in the consolidated statements of operations and consolidated statements of comprehensive income and amounts of gains and losses related to derivative instruments designated as cash flow hedges are as follows:
