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

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

[4] Short-term borrowings and long-term debt include foreign currency borrowings which are used as net investment hedges. The short-term borrowings’ carrying value as of December 31, 2021 was $1.1 billion. The long-term debt carrying values as of December 31, 2022 and December 31, 2021 were $795 million and $844 million, respectively.

[5] The amounts reclassified from OCI into COS were a net gain of $375 million in 2022 and a net loss of $89 million in 2021. 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 loss of $107 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 20 years and relates to foreign currency debt.
