Income Tax Disclosure [Abstract]  
INCOME TAXES INCOME TAXES
The income tax provision for interim periods is comprised of tax on ordinary income provided at the most recent estimated annual effective tax rate, adjusted for the tax effect of discrete items.  We estimate the annual effective tax rate quarterly based on the forecasted pre-tax results of our U.S. and non-U.S. operations. Items unrelated to current year ordinary income are recognized entirely in the period identified as a discrete item of tax.  These discrete items generally relate to changes in tax laws, adjustments to the actual liability determined upon filing tax returns, excess tax benefits related to share-based compensation and adjustments to previously recorded reserves for uncertain tax positions. For discussion of income tax accounting policies and other income tax related information, see Notes 2 and 17 of our 2025 Form 10-K.

Effective income tax rate

Our effective income tax rate was 23.1% for the nine months ended June 30, 2026, compared with 21.3% for our fiscal year 2025. The increase in the effective income tax rate was primarily driven by lower share-based compensation deductions in the current-year period compared with fiscal 2025, as well as the favorable impact on our fiscal 2025 effective income tax rate of the release of accruals for uncertain tax positions following the expiration of applicable statutes of limitations that did not reoccur in the current-year period. For additional information regarding our fiscal 2025 effective income tax rate, refer to Note 17 of our 2025 Form 10-K.

Uncertain tax positions

Although management cannot predict with any degree of certainty the timing of ultimate resolution of matters under review by various taxing jurisdictions, it is reasonably possible that our uncertain tax position liability balance may decrease within the next 12 months by up to $13 million due to expiration of statutes of limitations of federal and state tax returns.
