Disclosure of Compensation Related Costs, Share-based Payments [Abstract] |
Share-Based Compensation | 13. SHARE-BASED COMPENSATION We have granted various types of share-based payment awards to participants in the form of time based restricted stock units (“RSUs”), performance-based restricted stock units (“PRSUs”) and stock option grants. The key terms of our RSUs, PRSUs and our stock option grants, including all financial disclosures, are set forth in the 2015 Annual Report. These various types of share-based payment awards are subject to certain accelerated vesting clauses that vary by the award. Time-based Restricted Stock Units and Performance-based Restricted Stock Units In March 2016, we granted PRSUs to our executive officers for which the number of shares ultimately earned depends on our Company’s relative total shareholder return (“TSR”), as compared to a group of peer companies. The number of shares of our common stock to be awarded in connection with the vesting of those PRSUs ranges from 0 percent to 200 percent, with the percentage to be used in such vesting calculation based on the TSR performance metric. One-half of those executive officer PRSUs are scheduled to vest on the third anniversary of the grant date and the other one-half of those executive officer PRSUs are scheduled to vest on the fourth anniversary of the grant date, in each case so long as the executive officer remains employed with the Company through the applicable vesting date and subject to achievement of the performance metric. Also in March 2016, we granted PRSUs to certain of our executive officers for which the vesting depends on the Company having a positive Adjusted EBITDA for its 2016 fiscal year. Those PRSUs are scheduled to vest in three equal installments on each of the first, second and third anniversaries of the grant date, so long as the executive officer remains employed with the Company through the applicable vesting date and the Company achieves positive Adjusted EBITDA for its 2016 fiscal year. In addition, in March 2016, we granted time-based RSUs to certain of our executive officers, for which there is no performance metric, some of which are scheduled to vest in three equal installments on each of the first, second and third anniversaries of the grant date and the remainder of which are scheduled to vest in four equal installments on each of the first, second, third and fourth anniversaries of the grant date, provided, in each case, that the executive officer remains employed by the Company through the applicable vesting date. Also in March 2016, we granted time-based RSUs to non-officer employees, all of which are scheduled to vest in three equal installments on each of the first, second and third anniversaries of the grant date, so long as the employee remains employed with the Company through the applicable vesting date, and for which there is no performance metric. Share-based Compensation Expense Information regarding our share-based compensation expense for the three months ended March 31, 2016 and 2015 is as follows:
|  | Three Months Ended March 31, |
(In millions) |  | 2016 |  |  | 2015 |
Share-based compensation expense |  | $ | 2.0 |  |  | $ | 3.9 |
Income tax provision related to share-based compensation expense |  |  | (0.7) |  |  |  | (1.3) |
After tax share-based compensation expense |  | $ | 1.3 |  |  | $ | 2.6 |
During the three months ended March 31, 2016, we reversed approximately $0.9 million of expense related to share-based compensation due to the forfeiture of RSUs and PRSUs held by certain employees of the Company whose employment with the Company terminated prior to the vesting of those RSUs and PRSUs.
