Stockholders' Equity | 7. STOCKHOLDERS’ EQUITY Shares Available For Issuance In fiscal year 2007, we adopted the 2006 Stock Incentive Plan (“2006 Plan”). The 2006 Plan was amended in fiscal year 2010. Under the 2006 Plan, we may grant awards up to an aggregate amount of shares equal to the sum of: (i) 2,475 shares of Class A common stock (subject to adjustment in the event of stock splits and other similar events), plus (ii) such additional number of shares of Class A common stock as are currently subject to options granted under our 1993 Incentive Stock Option Plan, 1994 Non-statutory Stock Option Plan, 1996 Option Plan, and 1997 Plan (“Prior Plans”) which are not actually issued under the Prior Plans because such options expire or otherwise result in shares not being issued. As of July 31, 2013, there were 1,154 Class A common stock equivalents available for future grant under the 2006 Plan, inclusive of additional Class A common stock equivalents, which were previously issued under our terminated plans and which have become available for grant because such awards expired or otherwise resulted in shares not being issued. Stock Options Options granted under the 2006 Plan are granted at a price equal to the prevailing fair market value of our Class A common stock at the date of grant. Generally, options granted have a term not to exceed ten years and vest over a one to four year period from the date of grant. A summary of stock option activity for the three months ended July 31, 2013 is as follows:
|  | Stock Options |  |  | Weighted Average Exercise Price |  |  | Weighted Average Remaining Contractual Term (years) |  |  | Aggregate Intrinsic Value |

During the three months ended July 31, 2013 and 2012, stock-based compensation expense for stock options was $115 and $67, respectively. As of July 31, 2013, total unrecognized stock-based compensation expense related to outstanding stock options was $839, which will be recognized over a weighted average period of 2.2 years. Other Stock Awards Restricted stock awards, restricted stock units and performance stock units granted under the 2006 Plan are granted at a price equal to the fair market value of our Class A common stock at the date of grant. Restricted stock awards granted to non-employee directors vest incrementally over a three year period beginning on the first anniversary date of the grant. Restricted stock units vest incrementally over a three year period beginning on the first anniversary date of the grant and are based on continued employment. Performance stock units vest on April 30 th of the third fiscal year end following the grant date and are based on the attainment of a targeted average return on net assets as of the vesting date. A summary of restricted stock, restricted stock unit and performance stock unit activity for the three months ended July 31, 2013 is as follows:
|  | Restricted Stock, Restricted Stock Units, and Performance Stock Units (1) |  |  | Weighted Average Grant Price |  |  | Weighted Average Remaining Contractual Term (years) |  |  | Aggregate Intrinsic Value |

(1) | Performance stock units are included at the 100% attainment level. Attainment of maximum annual returns on net assets could result in the issuance of an additional 356 shares of Class A common stock.
During the three months ended July 31, 2013, we awarded certain employees restricted stock units, which vest incrementally over a three year period beginning on the first anniversary date of the grant and are based on continued employment.

The unrecognized stock-based compensation expense that we expect to recognize as of July 31, 2013 related to outstanding performance stock units based on our expected attainment levels was $0.
