[1]

These forward foreign exchange contracts were entered into to hedge fluctuations in foreign exchange rates for recognized balance sheet items such as receivables and intercompany borrowings, and were not originally designated as hedges under FASB guidance on derivatives and hedging. Realized gains (losses) and changes in the fair value of these derivatives are recorded in foreign exchange gains (losses), net in the consolidated statements of income.

[2]

These forward foreign exchange contracts were initially designated as cash flow hedges under ASC guidance on derivatives and hedging. These contracts were terminated because certain forecasted transactions were no longer expected to occur and therefore hedge accounting was no longer applied. Subsequently the realized gains (losses) are recorded in foreign exchange (gains) losses net in the consolidated statements of income.
