Stock-based compensation and equity transactions

Note 5 - 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. Incentive stock options granted during the quarter ended January 31, 2013 vest and are exercisable equally over three years and expire in five years from date of grant. During the three months ended January 31, 2013, the Company granted a total of 138,280 incentive stock options to company employees. 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 three months ended January 31, 2013 and 2012 was estimated to be $1.01 and $1.41 per share, respectively, using the Black-Scholes option pricing model with the following assumptions:

	2013			2012
Risk-free interest rate		0.36	%		0.39	%
Dividend yield		4.45	%		3.00	%
Expected life of the option		3.5 years			3.8 years
Volatility factor		42.46	%		65.65	%

Expected volatilities are based on historical volatility of the Company’s stock price and other factors. The Company used the historical method to calculate the expected life of the 2013 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 three months ended January 31, 2013, the Company issued 489,435 shares of common stock and received net proceeds of $1,313,723 in connection with the exercise of employee stock options.

As of January 31, 2013, $369,679 of expense with respect to nonvested share-based arrangements has yet to be recognized which is expected to be recognized over a weighted average period of 3.20 years.

Non-employee directors receive $25,000 annually, which amount is paid one-half in cash and one-half through the grant of stock options to purchase shares of the Company’s common stock. During the quarter ended January 31, 2013, the Company granted each of its four non-employee directors 8,405 options. The number of stock options granted to each director was determined by dividing $12,500 by the fair value of a stock option grant using the Black Scholes model ($1.49 per share). These options vest ratably over fiscal year 2013.
