Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]

Accounting for Stock-Based Compensation

The Company has a stock-based compensation plan under which employees and non-employee directors may be granted incentive stock options ("ISO's") and non-qualified stock options ("NQSO's") to purchase shares of Class A common stock. Under the plan, the exercise price of the ISO's will not be less than the market value of the Company's Class A common stock or greater than 110% of the market value of the Company's Class A common stock on the date of grant. The exercise price of the NQSO's may not be less than 50% of the market value of the Company's Class A common stock on the date of grant. The plan permits for options to be exercised at various intervals as determined by the Board of Directors. However, the maximum expiration period is ten years from date of grant. The vesting requirements are determined by the Board of Directors at the time of grant.  Exercised options are issued from authorized Class A common stock.  As of February 28, 2014, approximately 1,700,000 shares were available for future grants under the terms of these plans.

Options are measured at the fair value of the award at the date of grant and are recognized as an expense over the requisite service period. Compensation expense related to stock-based awards with vesting terms are amortized using the straight-line attribution method.
