Restricted Stock Awards and Units |
From time to time, we grant RSAs and RSUs to our employees. Unvested RSAs have the same rights as those of common shares including voting rights and non-forfeitable dividend rights. However, ownership of unvested RSAs cannot be transferred until they are vested. An unvested RSU is a contractual right to receive a share of common stock only upon its vesting. RSUs have dividend equivalent rights which accrue over the term of the award and are paid if and when the RSUs vest, but they have no voting rights. |
During the three months ended September 30, 2013 and 2012, the Board of Directors approved an immaterial amount of RSU grants. During the nine months ended September 30, 2013 and 2012, the Board of Directors approved RSU grants of 1.6 million and 0.9 million, respectively, of which 0.7 million and 0.4 million, respectively, were granted to certain executives as part of our performance incentive program. Half of these performance incentive program grants vest ratably on each of the first three anniversaries of the grant date; 25% will vest upon achievement of certain performance metrics; and the remaining 25% will vest one year from the date upon which certain performance metrics are achieved. If actual performance metrics exceed the targeted performance metrics by a predetermined amount, the executives are eligible to receive up to 200% of the performance-based portion of their award. During the three months ended September 30, 2013 and 2012, $2.2 million and $1.9 million, respectively, of stock-based compensation expense related to RSUs were recorded. During the nine months ended September 30, 2013 and 2012, $8.1 million and $5.1 million, respectively, of stock-based compensation expense related to RSUs were recorded. |
