The 2007 Long Term Incentive Plan, as amended (the “2007 Incentive Plan”), provides for the grant of incentive stock options, nonqualified stock options, restricted stock awards, stock appreciation rights, and performance awards to our officers, employees and non-employee directors to acquire shares of our Class A common stock, common stock or to receive other awards based on our performance. During the six-month period ended June 30, 2013, we granted 318,852 shares of restricted common stock to our executive officers. One-third of these shares will vest on each of March 19, 2014, March 19, 2015 and March 19, 2016. Also during the six-month period ended June 30, 2013, we granted 63,210 shares of restricted common stock to our non-employee directors. These shares will vest on January 1, 2014. During the six-month period ended June 30, 2012, we granted 432,396 shares of restricted common stock, which shares have vested, and we also granted options to acquire 359,568 shares of our common stock.

Also during the three-month and six-month periods ended June 30, 2013, the vesting dates of 107,224 of previously granted shares of restricted common stock and stock options to purchase 63,616 shares of common stock were accelerated, resulting in $1.0 million of stock-based compensation expense being recognized by the Company in those periods. Had these stock awards not been modified, these shares of restricted common stock and unvested stock options would have fully vested by March 19, 2016 and April 2, 2016, respectively. These stock awards were held by a former employee.

We did not have any stock options or restricted stock outstanding for our Class A common stock during any period presented.
