[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 September 29, 2024 and December 31, 2023 were $836 million and $824 million, respectively.

[4] The amounts reclassified from OCI into COS were: •a net gain of $37 million in the third quarter of 2024; •a net gain of $106 million in the first nine months of 2024; •a net gain of $49 million in the third quarter of 2023; and •a net gain of $195 million in the first nine months of 2023. 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 loss of $91 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.
