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

[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 in net investment hedges; the related carrying values as of March 30, 2025 and December 31, 2024 were $808 million and $777 million, respectively.

[4] The amounts reclassified from OCI into COS were a net gain of $62 million in the first quarter of 2025 and a net gain of $31 million in the first quarter of 2024. The remaining amounts were reclassified from OCI into OID. Based on quarter-end foreign exchange rates that are subject to change, we expect to reclassify a pre-tax gain of $94 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 18 years and relates to foreign currency debt.

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