Income Tax Disclosure [Abstract]  
Income Taxes
Income taxes are determined using the liability method of accounting for income taxes, under which deferred tax assets (“DTAs”) and deferred tax liabilities (“DTLs”) are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax basis of assets and liabilities. If, based upon all available evidence, both positive and negative, it is more likely than not that such DTAs will not be realized, a valuation allowance is recorded.
Management assessed the available positive and negative evidence to estimate whether sufficient future taxable income will be generated to permit use of existing DTAs in each taxpaying jurisdiction. On the basis of this evaluation, as of December 31, 2024, a valuation allowance of $67 million has been recorded to recognize only the portion of the DTAs that are more likely than not to be realized; however, the amount of the DTAs considered realizable could be adjusted if estimates of future taxable income during the carry forward period change or if objective negative evidence in the form of cumulative losses is no longer present and additional weight is given to subjective evidence such as projections for future growth.
We apply a recognition threshold and measurement attribute related to uncertain tax positions taken or expected to be taken on our tax returns. We recognize a tax benefit for financial reporting of an uncertain income tax position when it has a greater than 50% likelihood of being sustained upon examination by the taxing authorities. We measure the tax benefit of an uncertain tax position based on the largest benefit that has a greater than 50% likelihood of being ultimately realized including evaluation of settlements.

Our 2024 effective tax rate was impacted by the effect of worldwide tax rates on foreign earnings, offset by tax benefits of internal restructuring and tax credits. Our 2023 effective tax rate was impacted by the effect of worldwide tax rates on foreign earnings, offset by tax benefits of internal restructurings and the impact of the 2022 Divestitures. Our 2022 effective tax rate was impacted by not benefiting from year-to-date losses in continuing operations in accordance with the intraperiod tax expense (benefit) allocation rules as generally prescribed under ASC 740-20.
The Divestitures generated $674 million of net cash taxes, after usage of tax attributes. Of this amount, $641 million was paid in the year ended December 31, 2022 and the remainder was paid in the year ended December 31, 2023.
Deferred income taxes reflect the net tax effects of temporary differences between the carrying values of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The deferred income tax balances are established using the enacted statutory tax rates and are adjusted for changes in such rates in the period of change.

Undistributed earnings of subsidiaries are accounted for as a temporary difference, except that DTLs are not recorded for undistributed earnings of foreign subsidiaries that are deemed to be indefinitely reinvested in foreign jurisdictions. The Tax Cuts and Jobs Act of 2017 (“Tax Act”) required the Company to compute a tax on previously undistributed earnings and profits of its foreign subsidiaries upon transition from a worldwide tax system to a territorial tax system during the year ended December 31, 2017. The repatriation of such amounts in the future should generally be exempt from income taxes in the U.S. (as a result of the Tax Act) and in those jurisdictions that have a similar territorial system of taxation. Substantially all of our current year foreign cash flows are not intended to be indefinitely reinvested offshore, and therefore the tax effects of repatriation (including applicable withholding taxes) of such cash flows are provided for in our financial reporting.
Unrecognized Tax Benefits
The total amount of unrecognized tax benefits (“UTBs”) as of December 31, 2024 was $67 million. Of this amount, $67 million, if recognized, would be included in our Consolidated Statements of Operations and have an impact on our effective tax rate. During the fourth quarter of 2024, we recognized approximately $10 million of tax benefits due to expiration of statutes of limitations on tax positions.
We recognize interest and penalties for unrecognized tax benefits in income tax expense. The amounts recognized for interest and penalties during the years ended December 31, 2024, 2023 and 2022 were not material.
We file income tax returns in the U.S. Federal jurisdiction and various state and foreign jurisdictions. We are generally not subject to examination for periods prior to December 31, 2020; however, as we utilize our NOLs, prior periods can be subject to examination. During the second quarter of 2024, the Company was notified by the Internal Revenue Service that the Company’s U.S. federal income tax returns for tax years 2021 and 2022 are subject to examination. There are no other ongoing material U.S. state, local or non-U.S. examinations by tax authorities.
