Income Taxes [Abstract]
Income Taxes	(7) Income Taxes The Company’s effective income tax rate was 17.3% and 11.0% for the three and nine months ended September 30, 2019 and 22.5% and 26.2% for the three and nine months ended September 30, 2018, respectively. The Company’s provision for income taxes and effective tax rate for the nine months ended September 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 nine months ended September 30, 2019, the Company recognized a tax benefit totaling $50.4 million as a result of the impairment charge. Additionally, approximately $50.3 million was recorded as a deferred tax asset or a reduction of a previously recorded deferred tax liability due to the impairment charge. The effective tax rate for the three months ended September 30, 2019 of 17.3% and the adjusted effective income tax rate for the nine months ended September 30, 2019 of 25.1%, which excludes the goodwill impairment charge and associated tax benefit, were favorably impacted by earnings attributable to noncontrolling interests for which income taxes are not the responsibility of the Company and tax return-to-provision adjustments. The nine-month period ended September 30, 2019 also included 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. The effective tax rates for the 2018 periods were favorably impacted by the release of tax liabilities as a result of expirations of statutes of limitations and earnings attributable to noncontrolling interests for which income taxes are not the responsibility of the Company, partially offset by unfavorable rate impacts of share-based compensation-related changes. The effective tax rates for all periods also include provisions for state income taxes, net of the federal benefit.
