Income Taxes [Abstract] |
Income Taxes | (4) Income Taxes ﻿ The Company’s effective income tax rate for the three and six months ended June 30, 2017 was 37.9% and 37.6%, respectively, compared to 40.3% and 41.2% for the three and six months ended June 30, 2016, respectively. The effective tax rate for the three months ended June 30, 2017 was favorably impacted by earnings attributable to noncontrolling interests for which income taxes are not the responsibility of the Company. The effective tax rate for the six months ended June 30, 2017 was favorably impacted by earnings attributable to noncontrolling interests, reductions in estimated non-deductible expenses and tax benefits associated with share-based compensation. During the first quarter of 2017, t he Company recognized tax benefits associated with share-based compensation under the provisions of ASU 2016-09, as discussed in Note 9. This tax benefit is the result of a greater tax deduction for share-based compensation expense for awards that vested in the first quarter of 2017 relative to the share-based compensation expense recognized under GAAP for these same awards. The effective tax rate for the second quarter of 2016 was favorably impacted by adjustments related to uncertain tax benefits. The effective rate for the first half of 2016 reflects the favorable impact of the uncertain tax benefit adjustments, as well as the unfavorable impact of various discrete items, including certain state tax rate changes on deferred taxes. ﻿
