Income taxes

In December 2021, the Organization for Economic Cooperation and Development ("OECD") published a framework, known as Pillar Two, defining a global minimum tax of 15 percent on large corporations. The OECD has since issued administrative guidance providing transition and safe harbor rules around the implementation of the Pillar Two global minimum tax. Several countries have proposed or enacted legislation to implement core elements of the Pillar Two proposal effective for years beginning after December 31, 2023, which for us is fiscal year 2025. Pillar Two does not currently have a significant impact on our consolidated financial statements. Future legislation and guidance may result in a change to our assessment.

During the three months ended March 31, 2025, we completed an initiative that simplified our foreign legal entity structure. The initiative impacted our evaluation of certain foreign tax loss carryforwards whose realizability was previously considered to be remote. This led to a valuation allowance release and the recording of a $180 million discrete tax benefit.

Unrecognized tax benefits reflect the difference between positions taken or expected to be taken on income tax returns and the amounts reflected in the financial statements. As of March 31, 2025, we had gross unrecognized tax benefits of $82 million, all of which, if recognized, would impact the effective tax rate. The accrued interest and accrued penalties related to the gross unrecognized tax benefits, excluded from the amount above, is $22 million and $2 million, respectively. It is reasonably possible that within the next 12 months the amount of gross unrecognized tax benefits could be reduced by up to approximately $30 million as a result of the revaluation of existing uncertain tax positions arising from developments in the examination process or the closure of tax statutes. Any increase in the amount of gross unrecognized tax benefits within the next 12 months is expected to be insignificant.

We file income tax returns in the United States and in various foreign jurisdictions. In the normal course of business, we are subject to examination by taxing authorities throughout the world. We are open to assessment on our U.S. federal income tax returns by the Internal Revenue Service for fiscal years after 2013, and our state and local returns for fiscal years after 2018. We are also open to assessment for significant foreign jurisdictions for fiscal years after 2011.
