| Income Taxes | Income Taxes AWR’s effective income tax rate (“ETR”) was 24.8% and 24.0% for the three months ended March 31, 2026 and 2025, respectively. GSWC’s ETR was 25.9% and 24.7% for the three months ended March 31, 2026 and 2025, respectively. The AWR and GSWC ETRs differed from the federal corporate statutory tax rate of 21% primarily due to (i) state taxes; (ii) permanent differences, including certain tax effects from stock compensation; (iii) the ongoing amortization of the excess deferred income tax liability; and (iv) differences between book and taxable income that are treated as flowed-through adjustments in accordance with regulatory requirements (principally from plant, rate-case, and compensation-related items). As regulated utilities, GSWC and BVES treat certain temporary differences as flowed-through to customers in computing their income tax expense consistent with the income tax method used in their CPUC-jurisdiction rate making. Flowed-through items either increase or decrease tax expense and the ETR.
