Accounting Policies Associated with Derivative Instruments
We report the effective portion of the gain or loss on a derivative instrument designated and qualifying as a cash flow hedging instrument as a component of other comprehensive income. We reclassify the effective portion of the gain or loss on these derivative instruments into income in the same period or periods during which the hedged transaction affects earnings. The remaining gain or loss on the derivative instrument resulting from hedge ineffectiveness, if any, must be recognized currently in earnings.
Fair value hedges pertain to derivative instruments that qualify as a hedge of exposures to changes in the fair value of a firm commitment or assets and liabilities recognized on the balance sheet. For fair value hedges, our policy is to record the gain or loss on the derivative instrument in earnings in the period of change together with the offsetting loss or gain on the hedged item. The effect of that accounting is to reflect in earnings the extent to which the hedge is not effective in achieving offsetting changes in fair value.
As of December 31, 2009, we designated and accounted for all derivative instruments, including foreign exchange forward contracts and options and commodities futures and options contracts, as cash flow hedges. Additional information regarding accounting policies associated with derivative instruments is contained in Note 6, Derivative Instruments and Hedging Activities.
