The effective income tax rates were 17.2% and 5.1% for the three months ended March 31, 2023 and 2022, respectively. The higher effective income tax rate for the three months ended March 31, 2023, versus the comparable period in 2022, was primarily due to a prior year discrete tax benefit related to final U.S. tax regulations published in the first quarter of 2022, which resulted in a valuation allowance release of $333 million associated with the U.S. foreign tax credit carryforward deferred tax asset. Additionally, the U.K. statutory tax rate increase, effective in 2023, contributed to the higher effective income tax rate.
The Company is subject to tax in the United States, Belgium, Singapore, the United Kingdom and various other foreign jurisdictions, as well as state and local jurisdictions. Uncertain tax positions are reviewed on an ongoing basis and are adjusted after considering facts and circumstances, including progress of tax audits, developments in case law and closing of statutes of limitation. Within the next twelve months, the Company believes that the resolution of certain federal, foreign and state and local examinations is reasonably possible and that a change in estimate, reducing unrecognized tax benefits, may occur. While such a change may be significant, it is not possible to provide a range of the potential change until the examinations progress further or the related statutes of limitation expire. The Company has effectively settled its U.S. federal income tax obligations through 2014. With limited exception, the Company is no longer subject to state and local or foreign examinations by tax authorities for years before 2011.
