Effective income tax rate19.8 %22.5 %19.5 %19.7 %
The income tax provision as a percentage of income before income taxes and (loss) income from investments in unconsolidated affiliates was 19.8% and 22.5% for the three months ended September 30, 2023 and 2022, respectively, and 19.5% and 19.7% for the nine months ended September 30, 2023 and 2022, respectively. For the three months ended September 30, 2023, the effective income tax rate included tax benefits from subsidiary restructurings and the purchase of transferable renewable energy tax credits.
The effective income tax rate for both the nine months ended September 30, 2023 and 2022 included discrete tax benefits from subsidiary restructurings and equity compensation related tax benefits. The effective income tax rate for the nine months ended September 30, 2023 also included tax benefits from the purchase of transferable renewable energy tax credits.
The Company’s potential liability for unrecognized tax benefits before interest and penalties was approximately $84 million at September 30, 2023. The Company believes it is reasonably possible that the liability for unrecognized tax benefits may decrease by up to $7 million over the next twelve months as a result of possible closure of tax audits, audit settlements, and the lapse of the statutes of limitations in various jurisdictions.
As of September 30, 2023, the Company’s U.S. federal income tax return for 2022, and tax returns in certain states and foreign jurisdictions for 2015 through 2022, remain subject to examination by taxing authorities.
