Our effective tax rate for the three months ended March 31, 2025 and 2024 was 20% and 27%, respectively. The difference between our effective tax rate and the U.S. federal statutory rate of 21% in the periods presented was primarily the result of foreign income taxed at different rates, tax expense related to stock-based compensation, and other discrete tax adjustments.

The Organization for Economic Co-operation and Development (“OECD”) has published model rules, which include the implementation of a global minimum tax rate of 15%, commonly referred to as Pillar Two. Certain countries in which we do business enacted legislation that became effective as of January 1, 2025. Our effective tax rate for the three months ended March 31, 2025 includes the impact of Pillar Two minimum taxes in these jurisdictions.
Gross unrecognized tax benefits were approximately $2.4 billion and $2.3 billion as of March 31, 2025 and December 31, 2024, respectively. Due to various factors, including uncertainties of the judicial, administrative, and regulatory processes in certain jurisdictions, the timing of the resolution of these unrecognized tax benefits is highly uncertain. It is reasonably possible that within the next twelve months, we may receive additional tax adjustments by various tax authorities or possibly reach resolution of audits in one or more jurisdictions. These adjustments or settlements could result in changes to our unrecognized tax benefits related to positions on prior year tax filings. Given the number of years remaining subject to examination and the number of matters being examined, we were unable to estimate the full range of possible adjustments to the balance of gross unrecognized tax benefits.
