Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	STOCK-BASED COMPENSATION On December 31, 2015, performance share units (“PSUs”) granted in 2013 became fully vested. In addition, on December 31, 2014, PSUs granted in 2012 became fully vested. The EPS threshold associated with each of these awards was achieved at the maximum level, and 200% of the target shares were earned. These vested performance share units were net share settled. In connection with the issuance of the shares underlying these PSUs during the three months ended March 31, 2016 and 2015, the Company transferred 0.2 million and 0.2 million shares, respectively, into Treasury stock, based upon the Company’s closing stock price on the vesting date, to satisfy the employees’ minimum statutory withholding obligation for applicable income and other employment taxes. The Company then remitted the equivalent cash value to the appropriate taxing authorities. Total payments for the employees’ tax obligations to the relevant taxing authorities were $2.4 million and $2.6 million for the three months ended March 31, 2016 and 2015, respectively, and are reflected as a financing activity within the Condensed Consolidated Statements of Cash Flows.
