SHARE-BASED COMPENSATION |
16. | 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 2014 Annual Report. Time-based Restricted Stock Units and Performance-based Restricted Stock Units In May 2015, 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. All of those PRSUs are expected to vest on the third anniversary of the grant date. Also, in May 2015, we granted PRSUs to certain of our executive officers, for which the vesting depends on the Company having a positive Adjusted EBITDA for the prescribed performance period. Those PRSUs are scheduled to vest in three equal installments on each of the first, second and third anniversaries of the grant date. In addition, in May 2015, we granted RSUs to certain of our executive officers and non-officer employees, the majority of which are scheduled to vest in three equal installments on each of the first, second and third anniversaries of the grant date, and for which there is no performance metric.
