Income Tax Disclosure [Text Block] | 12. Income Taxes The effective tax rate for the first quarter of 2019 was 21.8% compared to 22.8% for the first quarter of 2018. The effective tax rate includes the impact of low-income housing and alternative energy investment tax credits. Income tax expense for the first quarter of 2019 was reduced by $0.5 million in benefits from the distribution of restricted stock units. The Company’s tax returns are open for audit by the Internal Revenue Service back to 2015 and by the California Franchise Tax Board back to 2014. 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.
