[1] The gain or loss on the effective portion of cash flow hedging relationships is reclassified from AOCI into net income in the same period during which the related item affects earnings. Such amounts are included in the Consolidated Statements of Earnings as follows: interest rate contracts in Interest expense and foreign currency contracts in Selling, general and administrative expense (SG&A) and Interest expense.

[2] The gain or loss on the ineffective portion of interest rate contracts and net investment hedges, if any, is included in the Consolidated Statements of Earnings in Interest expense.

[3] The gain or loss on foreign currency contracts not designated as hedging instruments is included in the Consolidated Statements of Earnings in SG&A. This gain or loss substantially offsets the foreign currency mark-to-market impact of the related exposure.
