[1] OCI is defined as other comprehensive income (loss).

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

[4] COGS is defined as costs of goods sold and other operating charges.

[5] 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, which were $(30), $(130) and $280 for 2011, 2010 and 2009, respectively.
