The effective tax rate for the six months ended March 31, 2025 was lower than the effective tax rate for the corresponding prior-year period primarily due to changes in the geographic mix of income before taxes. Additionally, for the six months ended March 31, 2025 and March 31, 2024, rates were impacted by a benefit of $10.4 million and an expense of $3.6 million, respectively, associated with the impact of changes in tax reserves related to prior years in foreign jurisdictions.
