Income Taxes [Abstract] |
Income Taxes | (7) Income Taxes ﻿ The Company’s effective income tax rate for the three and six months ended June 30, 2018 was 30.0% and 31.2%, respectively, compared to 37.9% and 37.6% for the three and six months ended June 30, 2017, respectively. The effective tax rates for the 2018 periods reflect the reduction in the federal statutory income tax rate from 35% to 21% effective January 1, 2018 as a result of the Tax Act and were favorably impacted by earnings attributable to noncontrolling interests for which income taxes are not the responsibility of the Company, partially offset by non-deductible expenses and a change in the New York State tax law related to the treatment of foreign income under the Tax Act. The effective tax rates for the three and six months ended June 30, 2017 were favorably impacted by earnings attributable to noncontrolling interests, while the effective rate for the six-month period was also favorably impacted by reductions in estimated non-deductible expenses and tax benefits associated with share-based compensation. For the three and six months ended June 30, 2018 and 2017, the effective tax rates were higher than the federal statutory rates primarily due to state income taxes.
