Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	STOCK-BASED COMPENSATION On December 31, 2016 and 2015, performance share units (“PSUs”) granted in 2014 and 2013, respectively, 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. In addition, during the three months ended March 31, 2017, certain restricted stock awards granted in 2014 became fully vested. These vested PSUs and restricted stock awards were net share settled. In connection with the issuance of the shares underlying these PSUs during the three months ended March 31, 2017 and 2016, and with the vesting of restricted stock, the Company transferred 0.1 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’ 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 $1.9 million and $2.4 million for the three months ended March 31, 2017 and 2016, respectively, and are reflected as a financing activity within the Condensed Consolidated Statements of Cash Flows.
