Income Tax Disclosure [Text Block] | 1 1. Income Taxes The effective tax rate for the third quarter of 2017 was 41.4% compared to 25.5% for the third quarter of 2016. The third quarter 2017 effective tax rate of 41.4% reflected additional tax expense to increase the full year effective tax rate to 34% compared to the 29% effective tax rate forecasted at June 30, 2017. This adjustment in the third quarter was the result of lower tax credits from the slow deployment of alternative energy investments. Income tax expense for the first quarter of 2017 was also reduced by $2.6 million in benefits from the distribution of restricted stock units and exercises of stock options. As of September 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 2014 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.
