Income Taxes Income Taxes
Numerous countries have agreed to a statement in support of the Organization for Economic Cooperation and Development ("OECD") model rules that propose a global minimum tax rate of 15%. Certain countries have enacted, or are in the process of enacting, legislation to address the global minimum tax. This legislation has not and is not expected to have a material impact on our Consolidated Financial Statements.

On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted in the United States. The OBBBA makes permanent key elements of the Tax Cuts and Jobs Act, including 100% bonus depreciation, domestic research cost expensing, and the business interest expense limitation. We are continuing to assess its impact and do not expect the OBBBA to have a material impact on our estimated annual effective tax rate.

Income taxes are recorded in our quarterly financial statements based on our estimated annual effective income tax rate, subject to adjustments for discrete events, should they occur. The effective tax rates used in the calculation of income taxes were 38.9% and 24.1% for the three months ended September 30, 2025 and 2024, respectively. The effective tax rates used in the calculation of income taxes were 31.5% and 20.5% for the six months ended September 30, 2025 and 2024, respectively. The increase in the effective tax rate for the six months ended September 30, 2025 compared to the six months ended September 30, 2024 was primarily due to establishing a taxable presence in a new state.
