Disclosure of Compensation Related Costs, Share-based Payments [Text Block] | 7. Stock-Based Compensation Long Term Incentive Plan 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 or common stock or to receive other awards based on our performance. We recognize the fair value of stock options granted on the date of grant as compensation expense, and such expense is amortized over the vesting period of the stock option. The 2007 Incentive Plan allows us to grant share-based awards for up to 6.0 million shares of stock, with not more than 1.0 million out of that 6.0 million being Class A common stock and the remaining shares being common stock. As of December 31, 2013, 5.0 million shares were available for issuance under the 2007 Incentive Plan. Shares of common stock underlying outstanding options and performance awards are counted as issued under the 2007 Incentive Plan. Under the 2007 Incentive Plan, the options granted typically vest after a two- to four-year period and expire three to eight years after vesting. However, options will vest immediately upon a “change in control” as such term is defined in the 2007 Incentive Plan. All options have been granted with purchase prices that equal the market value of the underlying stock at the close of business on the date of the grant. Included in corporate and administrative expenses in the years ended December 31, 2013, 2012 and 2011 were $2.0 million, $0.9 million and $0.1 million, respectively, of non-cash expense for stock-based compensation which included amortization of restricted stock and stock option expense. During the year ended December 31, 2013, we granted 318,852 shares of restricted common stock to our executive officers and as described below, 107,224 of these shares vested in the year ended December 31, 2013. Of the remaining shares granted to our executive officers, 70,542 shares will vest on each of March 19, 2014, March 19, 2015 and March 19, 2016. Also during the year ended December 31, 2013, we granted 63,210 shares of restricted common stock to our non-employee directors. These 63,210 shares vested on January 1, 2014. During the year ended December 31, 2013, the vesting dates of 107,224 previously granted shares of restricted common stock and stock options to purchase 63,616 shares of common stock held by a former employee were accelerated, resulting in $1.0 million of stock-based compensation expense being recognized by the Company in 2013. Had the vesting dates of these stock awards not been accelerated, these shares of restricted common stock and stock options would have fully vested by March 19, 2016 and April 2, 2016, respectively. During the year ended December 31, 2012, we granted 432,396 shares of restricted common stock to our executive officers and non-employee directors, and we also granted options to acquire 359,568 shares of our common stock to our executive officers. We later modified the terms of these shares of restricted stock. As a result of the modification, these 432,396 shares of restricted common stock became fully vested on December 14, 2012 and $0.4 million in stock-based compensation expense was recognized during the year ended December 31, 2012 that otherwise would have been recognized in later periods. Had these agreements not been modified, these shares of restricted common stock would have fully vested by April 2, 2015. The modifications affected the restricted stock granted to four executive officers and nine non-employee directors. During the year ended December 31, 2011, we did not grant any stock-based awards under this plan. A summary of stock option activity related to our common stock for the years ended December 31, 2013, 2012 and 2011 under our 2007 Incentive Plan is as follows:

Directors’ Restricted Stock Plan On May 14, 2003, our stockholders approved a restricted stock equity incentive plan for our Board of Directors (the “Directors’ Restricted Stock Plan”). We have reserved 1.0 million shares of our common stock for issuance under this plan and, as of December 31, 2013, there were 770,000 shares available for future award. Under the Directors’ Restricted Stock Plan, each director can be awarded up to 10,000 shares of restricted stock each calendar year. We did not grant any shares of restricted common stock to our directors under this plan during the years ended December 31, 2013, 2012 or 2011; however, we did grant certain awards under our 2007 Incentive Plan to members of our Board of Directors. All of the shares granted to the directors under the Directors’ Restricted Stock Plan since its inception were vested as of December 31, 2013. A summary of restricted stock activity related to our common stock for the years ended December 31, 2013, 2012 and 2011 under our Directors’ Restricted Stock Plan is as follows:
