[1] OID = Other (income)/deductions—net, included in Other (income)/deductions—net in the consolidated statements of income. COS = Cost of Sales, included in Cost of sales in the consolidated statements of income. OCI = Other comprehensive income/(loss), included in the consolidated statements of comprehensive income.

[2] Reclassified into Other (income)/deductions—net and Cost of sales. See Note 7E.

[3] Long-term debt includes foreign currency borrowings which are used as net investment hedges; the related carrying values as of December 31, 2023 and December 31, 2022 were $824 million and $795 million, respectively.

[4] The amounts reclassified from OCI into COS were a net gain of $253 million in 2023 and a net gain of $375 million in 2022. The remaining amounts were reclassified from OCI into OID. Based on year-end foreign exchange rates that are subject to change, we expect to reclassify a pre-tax gain of $11 million within the next 12 months into income. The maximum length of time over which we are hedging our exposure to the variability in future foreign exchange cash flows is approximately 19 years and relates to foreign currency debt.

[5] The amounts reclassified from OCI were reclassified into OID.
