[1] OCI is defined as other comprehensive loss.

[2] For cash flow hedges, this represents the effective portion of the gain (loss) reclassified from accumulated OCL into income during the period. For the years ended December 31, 2016, 2015 and 2014, there was no material ineffectiveness with regard to the company's cash flow hedges.

[3] Gain (loss) recognized in income of derivative is offset to $0 by gain (loss) recognized in income of the hedged item.

[4] Gain (loss) recognized in other income, net, was partially offset by the related gain (loss) on the foreign currency-denominated monetary assets and liabilities of the company's operations, see Note 5 for additional information.
