Income Taxes

For the three months ended September 30, 2023 and September 30, 2022, we recorded an income tax benefit of $11.0 million and an income tax expense of $20.6 million, respectively. For the nine months ended September 30, 2023 and September 30, 2022, we recorded an income tax benefit of $21.2 million and an income tax expense of $64.6 million, respectively. The change is primarily due to changes in pretax income amounts and jurisdictional mix on a year over year basis.

Our income tax expense or benefit for interim periods is determined using an estimate of our annual effective tax rate, adjusted for discrete items. The application of the accounting requirements for income taxes in interim periods, after consideration of our valuation allowance on domestic losses, causes a significant variation in the typical relationship between income tax expense/benefit and pre-tax accounting income/loss as reported on the Consolidated Statement of Operations.

As of September 30, 2023, all of Century's U.S. and certain foreign deferred tax assets, net of deferred tax liabilities, continue to be subject to a valuation allowance.

The Inflation Reduction Act of 2022 ("IRA") was signed into law on August 16, 2022, and the CHIPS and Science Act of 2022 was signed into law on August 9, 2022. These laws, effective January 1, 2023, implement new tax provisions, primarily a 15% corporate alternative minimum tax and a nondeductible 1% excise tax on the fair market value of stock repurchased by publicly traded corporations. As of September 30, 2023, these provisions, which were effective January 1, 2023, have not had any material impact on the financial statements. The IRA provides several tax incentives to promote clean energy and the production of critical minerals in the U.S. We are continuing to evaluate potential tax benefits available under the acts and expect the release of additional guidance from the U.S. Department of Treasury by the end of the year.
