Note 11 - Income Taxes	6 Months Ended
Jun. 30, 2015
Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	11. Income Taxes The effective income tax rates for the six months ended June 30, 2015 and 2014 were 36.3% and 35.1%, respectively. The increase in the effective income tax rate is partially attributable to a decrease in the Company’s federal domestic production activity deduction due to lower pre-tax income during the first half of 2015 compared to the first half 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; the gain was not taxable and decreased the effective tax rate during that period.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
