Disclosure of Compensation Related Costs, Share-based Payments [Text Block]	Note 8. Stock -Based Compensation Our 2006 Omnibus Incentive Plan, as amended (the "Incentive Plan") governs the issuance of equity awards and other incentive compensation to management and members of the board of directors. In February 2013, the Compensation Committee re-approved, subject to stockholder re-approval, the material terms of the performance-based goals under the Incentive Plan so that certain incentive awards granted thereunder would continue to qualify as exempt "performance-based compensation" under Internal Revenue Code Section 162 (m). Our stockholders re-approved the material terms of the performance-based goals under the Incentive Plan at our 2013 Annual Meeting held on May 29, 2013. The Incentive Plan permits annual awards of shares of our Class A common stock to executives, other key employees, consultants, non-employee directors, and eligible participants under various types of options, restricted stock awards, or other equity instruments. At June 30, 2017, 606,226 of the abovementioned 1,550,000 shares were available for award under the Incentive Plan. No participant in the Incentive Plan may receive awards of any type of equity instruments in any calendar-year that relates to more than 200,000 shares of our Class A common stock. No awards may be made under the Incentive Plan after March 31, 2023. Included in salaries, wages, and related expenses within the condensed consolidated statements of operations is $0.2 million and $0.3 million of stock-based compensation expense for the three months ended June 30, 2017 and 2016, and $0.4 million and $0.6 million of stock-based compensation expense for the six months ended June 30, 2017 and 2016, respectively. All stock compensation expense recorded in 2017 and 2016 relates to restricted shares, given no options were granted during these periods. An additional $0.3 million and $0.2 million of stock-based compensation was recorded in general supplies and expenses in the condensed consolidated statements of operations for each of the three - and six -month periods ended June 30, 2017 and 2016, respectively, as this amount relates to the issuance of restricted stock to non-employee directors. The Incentive Plan allows participants to pay the federal and state minimum statutory tax withholding requirements related to awards that vest or allows participants to deliver to us shares of Class A common stock having a fair market value equal to the minimum amount of such required withholding taxes. To satisfy withholding requirements for shares that vested, through June 30, 2017, certain participants elected to forfeit receipt of an aggregate of 10,803 shares of Class A common stock at a weighted average per share price of $18.81 based on the closing price of our Class A common stock on the dates the shares vested in 2017, in lieu of the federal and state minimum statutory tax withholding requirements. We remitted $0.2 million to the proper taxing authorities in satisfaction of the employees' minimum statutory withholding requirements.
