Stock-Based Compensation | 12. Stock-Based Compensation Stock Incentive Plans The Company has a stock-based compensation plan to attract, motivate, retain and reward employees, directors and consultants by providing its Board or a committee of the Board the discretion to award equity incentives to these persons. The Company’s stock-based compensation plan consists of the 2011 Incentive Compensation Plan (the “2011 Plan”), as amended. Shares are no longer available for issuance under the Company’s 2010 Bonus and Incentive Plan (the “2010 Plan”) and the 2007 Stock Option Plan (the “2007 Plan”). On June 6, 2011, the Company’s stockholders approved the 2011 Plan, which is administered by the Compensation Committee of the Board. The 2011 Plan provides that stock options, stock units, restricted shares, and stock appreciation rights may be granted to executive officers, directors, consultants, and other key employees. The Company reserved 400,000 shares of common stock under the 2011 Plan, plus 459,956 shares of common stock that remained available for delivery under the 2007 Plan and the 2010 Plan as of June 6, 2011. In aggregate, as of June 6, 2011, 859,956 shares were available for future grants under the 2011 Plan, including shares rolled over from 2007 Plan and 2010 Plan. Subsequent to June 6, 2011 through December 31, 2017, the number of shares of common stock authorized for issuance under the 2011 Plan has been increased by an aggregate of 3,000,000 shares. On May 31, 2018, the Company’s stockholders approved an amendment to the 2011 Plan to increase the number of shares of common stock authorized for issuance by 500,000 shares.
