Income Tax Disclosure [Abstract]  
Income Taxes Income Taxes
We apply an estimated annual effective tax rate to our year-to-date operating results to determine the interim provision for income tax expense. In addition, we recognize taxes related to unusual or infrequent items or resulting from a change in judgment regarding a position taken in a prior year as discrete items in the interim period in which the event occurs.
Our effective tax rates for the three months ended May 31, 2025 and 2024 were 24.0% and 25.4%, respectively. The lower effective tax rate for the three months ended May 31, 2025 was primarily due to lower tax expense from changes in the geographic distribution of earnings, partially offset by higher expense from adjustments to prior year tax liabilities. Our effective tax rates for the nine months ended May 31, 2025 and 2024 were 22.1% and 22.6%, respectively. The lower effective tax rate for the nine months ended May 31, 2025 was primarily due to lower tax expense from changes in the geographic distribution of earnings.
