Accounting for Stock-Based Compensation |
Note 3 — Accounting for Stock-Based Compensation We provide stock-based awards under the AAR CORP. Stock Benefit Plan (“Stock Benefit Plan”) which has been approved by our stockholders. Under the Stock Benefit Plan, we are authorized to issue stock options to employees and non-employee directors that allow the grant recipients to purchase shares of common stock at a price not less than the fair market value of the common stock on the date of grant. Generally, stock options awarded expire ten years from the date of grant and are exercisable in three, four or five equal annual increments commencing one year after the date of grant. We issue common stock upon the exercise of stock options. In addition to stock options, the Stock Benefit Plan also provides for the grant of restricted stock awards and performance-based restricted stock awards. The number of performance-based awards earned is based on achievement of certain Company-wide financial goals or stock price targets. The Stock Benefit Plan also provides for the grant of stock appreciation units and restricted stock units; however, to date, no such awards have been granted. We measure share-based compensation based on the fair value of the award at the grant date, and recognize the cost of share-based awards over the applicable service period, which is generally the vesting period. Performance-based restricted stock compensation is recognized over the applicable service period and based on the level of achievement that is considered probable. During the six-month periods ended November 30, 2011 and 2010, we granted stock options representing 162,281 shares and 708,970 shares, respectively. The weighted average fair value of stock options granted during the six-month periods ended November 30, 2011 and 2010 was $11.64 and $7.98, respectively. The fair value of each stock option grant was estimated on the date of grant using the Black-Scholes option pricing model with the following assumptions:
