Share-Based Compensation

8. Share-Based Compensation

On September 27, 2008 the University’s shareholders approved the adoption of the 2008 Equity Incentive Plan (“Incentive Plan”) and the 2008 Employee Stock Purchase (“ESPP”). A total of 4,200 shares of the University’s common stock was originally authorized for issuance under the Incentive Plan. On January 1 of each subsequent year in accordance with the terms of the Incentive Plan, the number of shares authorized for issuance under the Incentive Plan automatically increases by 2.5% of the number of shares of common stock issued and outstanding on the previous December 31, raising the total number of shares of common stock currently authorized for issuance under the Incentive Plan to 8,729 shares effective January 1, 2012. Although the ESPP has not yet been implemented, a total of 1,050 shares of the University’s common stock has been authorized for sale under the ESPP.

A summary of the activity related to stock options granted under the University’s Incentive Plan since December 31, 2011 is as follows:
