Income Tax Disclosure [Text Block]	8 – Income Taxes The Company had unrecognized income tax benefits totaling $2.6 million as a component of accrued liabilities at March 31, 2018 and December 31, 2017, the total of which, if recognized, would impact the Company’s effective tax rate. An unfavorable settlement may require a charge to income tax expense and a favorable resolution would be recognized as a reduction to income tax expense. The Company recognizes interest accrued related to unrecognized tax benefits in income tax expense. No amounts were accrued for penalties. The Company had approximately $166,000 accrued for the payment of interest at March 31, 2018 and December 31, 2017. On December 22, 2017, the United States Congress enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (“the Tax Act”). The Tax Act included, among other items, a reduction of the U.S. federal corporate tax rate from 35% to 21% effective January 1, 2018. The Tax Act made broad and complex changes to the U.S. tax code, some of which affected the Company’s 2017 year end results. Staff Accounting Bulletin No. 118 (SAB 118 ) provided guidance that allowed registrants to provide a reasonable estimate of the effects of the Tax Act in their financial statements and adjust the reported impact in a measurement period not to exceed one year. At December 31, 2017, the Company made a reasonable estimate of the effects of the Tax Act on its existing deferred tax balances and recognized a provisional net tax benefit of $82.9 million. The provisional benefit recorded was primarily a result of the remeasurement of the Company’s deferred tax assets and liabilities at the tax rate in which they will reverse when they are recognized. The Company will continue to refine its calculations as additional analysis is completed. In addition, the Company’s estimates may also be affected as it gains a more thorough understanding of the Tax Act. The Company does not anticipate a significant change in the amount of unrecognized tax benefits in the next 12 months. As of March 31, 2018, the tax years ended December 31, 2014 through 2017 remain subject to audit by federal tax authorities and the tax years ended December 31, 2013 through 2017 remain subject to audit by state tax authorities. In March 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016 - 09, “ Compensation – Stock Compensation (Topic 718 ), ” which changed the accounting for certain aspects of share-based payments to employees. The Company adopted this standard on January 1, 2017. ASU 2016 - 09 requires excess tax benefits and tax deficiencies to be recognized as income tax benefit or expense in the income statement and presented as an operating activity in the statement of cash flows when the awards are vested or are settled. The Company had a tax deficiency of $22,000 in the first quarter of 2018, which was recorded as an increase to income tax expense, and excess tax benefits of $1.1 million in the first quarter of 2017, which was recorded as a reduction to income tax expense in the Consolidated Statement of Income and Comprehensive Income.
