8. Share-Based Compensation

Incentive Plan

Restricted Stock

During the six months ended June 30, 2014, the University granted 298 shares of common stock with a service vesting condition to certain of its executives, officers, faculty and employees. The restricted shares have voting rights and vest in five annual installments of 20% starting on March 1, 2015 and each of the four anniversaries of the vesting date following the date of grant. Upon vesting, shares will be held in lieu of taxes equivalent to the minimum statutory tax withholding required to be paid when the restricted stock vests. During the six months ended June 30, 2014, the University withheld 77 shares of common stock in lieu of taxes at a cost of $3,662 on the restricted stock vesting dates. In May 2014, the University granted 8 shares of common stock to certain of the non-employee members of the University’s board of directors. The restricted shares granted to these directors have voting rights and vest on the earlier of (a) the one year anniversary of the date of grant or (b) immediately prior to the following year’s annual meeting of stockholders, subject to acceleration in the event of a change in control.
