Our income tax provision reflects an effective tax rate on pre-tax income of 26% and 20% for the three and six months ended March 31, 2025, respectively, compared to 24% and 22% for the three and six months ended March 31, 2024, respectively. The effective tax rates for the three and six months ended March 31, 2025 were favorably impacted by the estimated Research and Development (R&D) Tax Credit, which was offset by the tax expense related to certain nondeductible items. In addition, discrete items related to the vesting of RSUs recorded in the first quarter of Fiscal 2025 favorably impacted the effective tax rate for the six months ended March 31, 2025. Similarly, the effective tax rates for the three and six months ended March 31, 2024 were favorably impacted by the estimated R&D Tax Credit and discrete items related to the release of a reserve for unrecognized tax benefits upon expiration of the statute of limitations. These items were offset by an income inclusion related to U.S. global intangible income.
