Notes to Financial Statements
Income Tax Disclosure [Text Block]	12 . Income Taxes The effective income tax rates for the nine months ended September 30, 2015 and 2014 were 36.2% and 34.6%, respectively. The increase in the effective income tax rate is primarily attributable to a decrease in the Company’s federal domestic production activity deduction due to lower pre-tax income during the first nine months of 2015 compared to the first nine months of 2014. In addition, during the second quarter of 2014, the Company recognized a gain related to certain earn-out obligation adjustments in connection with acquisitions. This gain was not taxable and decreased the effective tax rate during that period.
