Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the three months ended March 31, 2014 and 2013, our income tax provision was $25.5 million and $19.0 million, respectively, based on effective income tax rates, before discrete items and less amounts attributable to noncontrolling interests, of 38.1% and 38.5%, respectively. The actual income tax rates on income before income taxes, less amounts attributable to noncontrolling interests, for the three months ended March 31, 2014 and 2013, inclusive of discrete items, were 38.2% and 38.7%, respectively. The increase in the 2014 income tax provision was primarily due to increased income before income taxes. As of March 31, 2014 and December 31, 2013, the amount of unrecognized income tax benefits was $2.4 million and $3.1 million (of which $0.9 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 March 31, 2014 and December 31, 2013, we had approximately $0.2 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 March 31, 2014 and 2013, less than $0.1 million and $0.2 million of interest expense was recognized, respectively. It is possible that approximately $0.1 million of unrecognized income tax benefits at March 31, 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 2011.
