Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the three months ended June 30, 2017 and 2016, our income tax provision from continuing operations was $33.0 million and $32.9 million, respectively, based on an effective income tax rate, before discrete items and less amounts attributable to noncontrolling interests, of 37.5% for both periods. The actual income tax rate on income from continuing operations, less amounts attributable to noncontrolling interests, for the three months ended June 30, 2017 and 2016, inclusive of discrete items, was 36.8% for both periods. For the six months ended June 30, 2017 and 2016, our income tax provision from continuing operations was $59.9 million and $51.9 million, respectively, based on effective income tax rates, before discrete items and less amounts attributable to noncontrolling interests, of 37.7% and 37.6%, respectively. The actual income tax rates on income from continuing operations, less amounts attributable to noncontrolling interests, for the six months ended June 30, 2017 and 2016, inclusive of discrete items, were 35.3% and 36.3%, 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 reversal of reserves for previously unrecognized income tax benefits in the first quarter of 2017. As of June 30, 2017 and December 31, 2016, the amount of unrecognized income tax benefits was $1.9 million and $4.0 million (of which $0.6 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 June 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 June 30, 2017 and 2016, $0.1 million and less than $0.1 million of interest expense, respectively, was recognized in the income tax provision. For the six months ended June 30, 2017 and 2016, $0.3 million of interest income and less than $0.1 million of interest expense, respectively, was recognized in the income tax provision. It is reasonably possible that approximately $1.2 million of unrecognized income tax benefits at June 30, 2017, primarily relating to uncertain tax positions attributable to tax return filing positions, will significantly decrease in the next twelve months as a result of estimated settlements with taxing authorities. 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.
