Income Tax Disclosure [Text Block] | 1 0. Income Taxes I ncome tax expense totaled $35.9 million, or an effective tax rate of 26.4%, for the six months ended June 30, 2017, compared to an income tax expense of $34.9 million, or an effective tax rate of 30.1%, for the same period in 2016. The effective tax rate includes the impact of the utilization of low income housing tax credits and the utilization of alternative energy tax credits. Also, ASU 2016 - 09 resulted in a $2.5 million tax benefit from the distribution of restricted stock units in the first six months ended June 30, 2017. As of June 30, 2017 and December 31, 2016, the Company had income tax refunds receivable of $19.4 million and $14.6 million, respectively. These income tax receivables are included in other assets in the accompanying condensed consolidated balance sheets. The Company ’s tax returns are open for audit by the Internal Revenue Service back to 2013 and by the California Franchise Tax Board back to 2012. As the Company is presently under audit by a number of tax authorities, 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.
