​ Our worldwide income tax expense for 2023 was $79.2 million compared to $61.5 million for 2022. The increase in tax expense was primarily attributable to changes in the operating income and the geographic mix of our pre-tax earnings (losses) in the jurisdictions in which we operate. ​ The components of our net deferred taxes consisted of the following: ​

​ As of December 31, 2023, we had federal, state, and foreign net operating loss (“NOL”) carryforwards of approximately $588.9 million, $788.1 million and $16.1 billion, respectively. Of those amounts, $7.9 billion will expire between 2024 and 2044 if not utilized. We provide a valuation allowance against NOL carryforwards in various tax jurisdictions based on our consideration of existing temporary differences and expected future earning levels in those jurisdictions. A valuation allowance of approximately $3.9 billion as of December 31, 2023 has been recognized related to certain NOL carryforwards as we believe it is more likely than not that the benefit of these NOL carryforwards will not be realized. ​ The following is a reconciliation of our uncertain tax positions: ​

​ If the unrecognized tax benefits of $34.0 million are realized, this would favorably impact the worldwide effective tax rate. As of December 31, 2023, 2022 and 2021, we had approximately $11.1 million, $17.0 million and $14.4 million, respectively, of interest and penalties related to uncertain tax positions. During 2023, 2022 and 2021, we accrued and recognized estimated interest and penalties related to uncertain tax positions of approximately $(6.0) million, $2.6 million and $6.9 million, respectively. During the fourth quarter of 2023, we settled tax audits for which we had accrued an uncertain tax position of $13.4 million and interest and penalties of $9.9 million. Upon settlement, we reversed the uncertain tax position accrual and related interest and penalties. We include potential interest and penalties related to uncertain tax positions within our global operations in the income tax expense (benefit) line item in our consolidated statements of income (loss). ​ It is reasonably possible that our existing liabilities related to our reserve for uncertain tax positions may increase or decrease in the next twelve months primarily due to the completion of open audits or the expiration of statutes of limitation. However, we cannot reasonably estimate a range of changes in our existing liabilities due to various uncertainties, such as the unresolved nature of various audits. ​ We conduct business globally and, as a result, we file numerous income tax returns in the U.S. and non-U.S. jurisdictions. In the normal course of business we are subject to examination by taxing authorities throughout the world, including major jurisdictions such as Colombia, Mexico, Saudi Arabia, Norway and the United States. We are no longer subject to U.S. Federal income tax examinations for years before 2020 and non-U.S. income tax examinations for years before 2007. ​ On August 16, 2022, the Inflation Reduction Act (“IRA”) was signed into law in the United States. Among other provisions, the IRA includes a 15% corporate minimum tax rate applied to certain large corporations and a 1% excise tax on corporate stock repurchases made after December 31, 2022. We do not expect the IRA to have a material impact to the Company. ​ The Organization Economic Co-operation and Development (“OECD”) introduced Base Erosion and Profit Shifting (“BEPS”) Pillar 2 rules that impose a global minimum tax rate of 15%. Numerous countries, including European Union member states, have enacted or are expected to enact legislation to be effective as early as January 1, 2024, with general implementation of a global minimum tax by January 1, 2025. There are no impacts to our consolidated financial statements for the year ended December 31, 2023. ​ On December 18, 2023, Bermuda enacted a 15% corporate income tax regime (the “Bermuda CIT”) that applies to Bermuda businesses that are part of multinational enterprise groups with annual revenue of €750 million or more and is effective for tax years beginning on or after January 1, 2025. As a result of the Bermuda CIT, the Company’s exemption from Bermuda corporate income taxes will cease in 2025. With the enactment of the Bermuda CIT in 2023, the Company underwent an analysis to determine the tax impacts to its consolidated financial statements for the year ended December 31, 2023. Bermuda CIT allows for a beginning net operating loss balance related to the five years preceding the effective date of Bermuda CIT. We have recorded a deferred tax asset of $171.9 million for the Bermuda net operating losses generated from 2020 through 2023 with an offsetting valuation allowance of $171.9 million.
