Note 6 - Stock-based compensation and equity transactions

 

The stock incentive plans provide for the granting of qualified and nonqualified options to the Company’s officers, directors and employees. Non-qualified stock options granted during the six months ended April 30, 2012 vest and are exercisable immediately with an expiration of five years from date of grant. During the six months ended April 30, 2012, the Company granted a total of 28,500 non-qualified stock options to its directors. The Company satisfies the exercise of options by issuing previously unissued common shares.

 

The weighted average fair value of employee stock options granted by the Company in the six months ended April 30, 2012 and 2011 was estimated to be $1.33 and $0.99 per share, respectively, using the Black-Scholes option pricing model with the following assumptions:

 

    2012     2011  
Risk-free interest rate     0.39 %     1.03 %
Dividend yield     4.99 %     1.91 %
Expected life of the option     3.5 years       2.5 years  
Volatility factor     66.16 %     55.78 %

 

Expected volatilities are based on historical volatility of the Company’s stock and other factors. The Company used the expected term method to calculate the expected life of the 2012 option grants. The expected life represents the period of time that options granted are expected to be outstanding. The risk-free rate is based on the U.S. Treasury rate with a maturity date corresponding to the options’ expected life. The dividend yield is based upon the historical dividend yield. 

 

Issuances of common stock by the Company

 

During the six months ended April 30, 2012, the Company issued 74,175 shares of common stock and received net proceeds of $76,351 in connection with the exercise of employee stock options.
