Income Taxes [Abstract]
Income Taxes	(7) Income Taxes The Company’s effective income tax rate was 12.0% and 11.6% for the three and six months ended June 30, 2019, respectively, and 30.0% and 31.2% for the three and six months ended June 30, 2018. The Company’s provision for income taxes and effective tax rates for the three and six months ended June 30, 2019 were significantly impacted by the goodwill impairment charge discussed in Note 8, Goodwill and Intangible Assets. Of the total goodwill impairment charge of $379.9 million, approximately $209.5 million pertained to goodwill that is not tax deductible and yielded permanent differences between book income and taxable income. For the three and six months ended June 30, 2019, the Company recognized a tax benefit totaling $50.4 million as a result of the impairment charge. Additionally, approximately $50.4 million was recorded as a deferred tax asset or a reduction of a previously recorded deferred tax liability due to the impairment charge. The adjusted effective income tax rates, which exclude the tax benefit resulting from the goodwill impairment charge, were 34.7% and 34.0% for the three and six months ended June 30, 2019, respectively, and primarily reflect the unfavorable impact of expired stock options for which the share-based compensation expense recognized in prior periods will not be deductible for income taxes. For the three and six months ended June 30, 2019 and 2018, the effective tax rates were higher than the federal statutory rates also as a result of state income taxes, with the increases partially offset by earnings attributable to noncontrolling interests for which income taxes are not the responsibility of the Company.
