Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the three months ended September 30, 2014 and 2013, our income tax provision on income from continuing operations was $24.0 million and $24.0 million, respectively, based on effective income tax rates, before discrete items and less amounts attributable to noncontrolling interests, of 37.6% and 39.5%, respectively. The actual income tax rates on income from continuing operations, less amounts attributable to noncontrolling interests, for the three months ended September 30, 2014 and 2013, inclusive of discrete items, were 34.5% and 44.7%, respectively. For the nine months ended September 30, 2014 and 2013, our income tax provision on income from continuing operations was $75.4 million and $60.6 million, respectively, based on effective income tax rates, before discrete items and less amounts attributable to noncontrolling interests, of 37.6% and 37.5%, respectively. The actual income tax rates on income from continuing operations, less amounts attributable to noncontrolling interests, for the nine months ended September 30, 2014 and 2013, inclusive of discrete items, were 36.6% and 38.8%, respectively. The increase in the 2014 income tax provision was primarily due to increased income before income taxes. The decrease in the actual income tax rates on income from continuing operations was primarily due to a change in the mix of earnings among various jurisdictions and the quarterly variance in discrete items. As of September 30, 2014 and December 31, 2013, the amount of unrecognized income tax benefits was $4.3 million and $3.1 million (of which $2.2 million and $1.7 million, if recognized, would favorably affect our effective income tax rate, respectively.) We report interest expense related to unrecognized income tax benefits in the income tax provision. As of September 30, 2014 and December 31, 2013, we had approximately $0.3 million of accrued interest related to unrecognized income tax benefits included as a liability in the Condensed Consolidated Balance Sheets. For the three months ended September 30, 2014 and 2013, less than $0.1 million and $0.2 million of interest expense was recognized, respectively. For the nine months ended September 30, 2014 and 2013, less than $0.1 million of interest income and $0.6 million of interest expense was recognized, respectively. It is possible that approximately $0.1 million of unrecognized income tax benefits at September 30, 2014, primarily relating to uncertain tax positions attributable to compensation related accruals, will become recognized income tax benefits in the next twelve months due to the expiration of applicable statutes of limitations. 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 2008 through 2013. During the first quarter of 2014, the Internal Revenue Service finalized its audit of our federal income tax returns for the years 2010 through 2011. We agreed to and paid an assessment, for an immaterial amount, proposed by the Internal Revenue Service pursuant to such audit.
