Income Tax Disclosure [Text Block] | 11. Income Taxes The effective tax rate for the first six months of 2025 was 19.7% compared to 9.4% for the first six months of 2024. The effective tax rate for the first six months of 2025 includes the impact of low-income housing tax credits and for the first six months of 2024 includes the impact of alternative energy investment and low-income housing tax credits. The Company’s tax returns are open for audit by the Internal Revenue Service back to 2022 and by the California Franchise Tax Board back to 2021. It is reasonably possible that unrecognized tax benefits could change significantly over the next twelve months. The Company does not expect that any such changes would have a material impact on its annual effective tax rate.
