Summary of Income Tax Effect Associated With Various Components of Other Comprehensive Loss

The income tax effect associated with the various components of other comprehensive loss for the years ended December 31, 2023 and 2022 is summarized below. Amounts in parentheses represent credits to net (loss) income when reclassified to earnings. Certain amounts have no tax effect due to the Corporation having a valuation allowance recorded against the deferred income tax assets for the jurisdiction where the income or expense is recognized. Foreign currency translation adjustments exclude the effect of income taxes since earnings of non-U.S. subsidiaries are deemed to be re-invested for an indefinite period of time.
