Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Income tax expense for the quarter and year to date period ended June 30, 2016 was $3,570 and $7,442, respectively, for an effective tax rate for the quarter of 36.1 percent and for the year to date period of 35.8 percent. The effective tax rate differs from the 35 percent federal statutory rate on pretax income primarily due to the impact of state income taxes and the domestic production activities deduction. The Company continues to evaluate all available positive and negative evidence to determine the likelihood of realization of the deferred tax assets. Income tax expense for the quarter and year to date period ended June 30, 2015 was $4,599 and $7,658, respectively, for an effective tax rate for the quarter of 36.9 percent and for the year to date period of 37.2 percent. The principal reason for the reduction in the Company’s effective tax rate in the current quarter and year to date period compared to the prior year quarter and year to date period is that the federal domestic production activities deduction is no longer limited by the Company's net operating loss carryovers from prior periods, as it was in the comparative quarter and year to date period.
