Long-term debt includes foreign currency borrowings, which are used in net investment hedges; the related carrying values as of June 30, 2024 and December 31, 2023 were $799 million and $824 million, respectively.[4]
The amounts reclassified from OCI into COS were:•a net gain of $38 million in the second quarter of 2024;•a net gain of $70 million in the first six months of 2024;•a net gain of $55 million in the second quarter of 2023; and•a net gain of $146 million in the first six 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 gain of $157 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]

Based on quarter-end foreign exchange rates that are subject to change, we expect to reclassify a pre-tax gain of $157 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.
