(i) Amounts were net of immaterial tax.

(ii) Our foreign exchange derivatives and interest rate swaps that we entered into prior to 2024 were not designated as effective cash flow hedges under GAAP until January 1, 2024. As a result, those derivatives and swaps did not qualify for hedge accounting in 2023 such that changes in their fair values were marked-to-market through our consolidated statements of operations (as miscellaneous expense (income)) instead of being deferred in AOCI. See note 18.
