Stock-Based Compensation Plans
13.           STOCK-BASED COMPENSATION PLANS

Pursuant to our Amended and Restated Incentive Compensation Plan (the "Incentive Plan"), the number of shares reserved for granting of restricted stock, restricted stock units, stock options, and performance awards to team members, officers, directors, and contractors at any time prior to April 6, 2019 is 1.5 million shares.  The shares available for future grants under the Incentive Plan totaled 342,560 as of December 31, 2011.

A summary of the restricted stock activity under the Incentive Plan for the years ended December 31, 2011, 2010, and 2009 is presented below:

The shares of restricted stock are part of the annual incentive compensation program and are granted annually based on attaining certain individual and company performance criteria.  The grant-date fair value per share is estimated to equal the market price of our common stock on the date of grant.  Based on the terms of individual restricted stock grants, time-based shares vest over a period of three to five years, based on continuous employment.

The distribution date of vested restricted stock units is February 22, 2014 for 60 restricted stock units and February 22, 2016 for 90 restricted stock units and February 22, 2017 for 8 restricted stock units.

The restricted stock units are part of a long-term incentive compensation program.  Each restricted stock unit represents and has a value equal to one share of common stock.  The grant-date fair value per share is estimated to equal the market price of our common stock on the date of grant.  The restricted stock units will be earned over a five year period based upon the compounded annual growth rate in our adjusted economic profit, a non-GAAP financial measure.

Pursuant to our 1992 Stock Option Plan (the "1992 Plan"), we had reserved 8.0 million shares of our common stock for the future granting of options to officers and other team members.  Pursuant to our Director Stock Option Plan (the "Director Plan"), we had reserved 200,000 shares of our common stock for future granting of options to members of our Board of Directors.  The exercise price of the options is no less than the fair market value on the date of the grant.  Options expire ten years from the date of grant.  The 1992 Plan and the Director Plan were terminated as to future grants on May 13, 2004, with shareholder approval of the Incentive Plan.  All options outstanding as of December 31, 2011 and 2010 are vested.

While the restricted stock units are expected to vest in equal, annual installments over a five-year period, the related stock-based compensation expense is not recognized on a straight-line basis over this period.  Each installment is accounted for as a separate award and as a result, the fair value of each installment is recognized as stock-based compensation expense on a straight-line basis over the related vesting period.  The following table details how the expenses associated with restricted stock and restricted stock units, which are expected to be recognized over a weighted average period of 1.3 years, will be recorded assuming performance targets are achieved in the periods currently estimated:
