Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the three months ended September 30, 2017 and 2016, our income tax provision from continuing operations was $38.6 million and $30.8 million, respectively, based on an effective income tax rate, before discrete items and less amounts attributable to noncontrolling interests, of 37.1% and 38.1%, respectively. The actual income tax rate on income from continuing operations, less amounts attributable to noncontrolling interests, for the three months ended September 30, 2017 and 2016, inclusive of discrete items, was 37.3% and 37.2%, respectively. For the nine months ended September 30, 2017 and 2016, our income tax provision from continuing operations was $98.5 million and $82.7 million, respectively, based on effective income tax rates, before discrete items and less amounts attributable to noncontrolling interests, of 37.4% and 37.8%, respectively. The actual income tax rates on income from continuing operations, less amounts attributable to noncontrolling interests, for the nine months ended September 30, 2017 and 2016, inclusive of discrete items, were 36.0% and 36.7%, respectively. The increase in the 2017 income tax provision was primarily due to increased income from continuing operations. The decrease in the 2017 actual income tax rate on income from continuing operations was due to the net impact of discrete items, inclusive of the reversal of reserves for previously unrecognized income tax benefits in the first quarter of 2017. As of September 30, 2017 and December 31, 2016, the amount of unrecognized income tax benefits was $1.9 million and $4.0 million (of which $0.7 million and $2.2 million, if recognized, would favorably affect our effective income tax rate), respectively. We report interest expense and/or income related to unrecognized income tax benefits in the income tax provision. As of September 30, 2017 and December 31, 2016, we had approximately $0.2 million and $0.5 million, respectively, of accrued interest expense related to unrecognized income tax benefits included as a liability in the Condensed Consolidated Balance Sheets. For the three months ended September 30, 2017 and 2016, less than $0.1 million of interest expense and less than $0.1 million of interest income, respectively, was recognized in the income tax provision. For the nine months ended September 30, 2017 and 2016, $0.3 million and less than $0.1 million of interest income, respectively, was recognized in the income tax provision. We do not anticipate any significant changes to our reserves for uncertain tax positions in the next twelve months. We file income tax returns with the Internal Revenue Service and various state, local and foreign tax agencies. The Company is currently under examination by various taxing authorities for the years 2012 through 2015. During the first quarter of 2017, the Company settled an examination with a taxing authority which resulted in the recognition of $3.3 million of income tax benefits upon the reversal of reserves for previously uncertain tax positions.
