Stock Options

11. Stock Options

In September 2009, we adopted the 2009 Employee Incentive Stock Plan (“2009 Plan”). The 2009 Plan provides for the award of stock options up to 200,000 shares and includes option awards as well as stock awards. Option awards are granted with the restriction of requiring payment for the shares. Stock awards are granted without restrictions and without payment by the recipient. Neither option awards nor stock awards may exceed 25,000 shares granted to any one individual in any fiscal year. Stock options may be an incentive stock option or a nonqualified stock option. Options to purchase common stock under the plan are granted at the fair market value of the common stock at the date of grant, become exercisable to the extent of 25% of the shares optioned on each of four anniversaries of the date of grant, expire ten years from the date of grant and are subject to forfeiture if employment terminates. The 2009 Plan expires ten years from the date of adoption.

According to our employee stock incentive plan, new shares will be issued upon the exercise of stock options and the Company can repurchase shares exercised under the plan. The plan also provides for the granting of stock awards. No stock awards were granted during fiscal 2013, 2012 and 2011.

We recognized compensation expense of $138,303, $120,124 and $51,350 in general and administrative expense in the Consolidated Statements of Operations for fiscal 2013, 2012 and 2011, respectively. The total cost related to non-vested awards not yet recognized at March 31, 2013 totals $111,644, which is expected to be recognized over a weighted average of 2.1 years.

The fair value of each stock option is estimated on the date of grant using the Binomial valuation model. Expected volatilities are based on historical volatility of the Company’s stock over the contractual term of 120 months and other factors. We use historical data to estimate option exercise and employee termination within the valuation model. The expected term of options granted is derived from the output of the option valuation model and represents the period of time that options granted are expected to be outstanding. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. As the Company has never declared dividends, no dividend yield is used in the calculation. Actual value realized, if any, is dependent on the future performance of the Company’s common stock and overall stock market conditions. There is no assurance the value realized by an optionee will be at or near the value estimated by the Binomial model.

During the year ended March 31, 2013, no stock options were granted. During the year ended March 31, 2012, the Compensation Committee of the Board of Directors approved and we issued 40,000 stock options to board members, officers and employees of Mexco exercisable at $6.80 per share. During the year ended March 31, 2011, the Compensation Committee of the Board of Directors approved and we issued 42,500 stock options to board members, officers and employees of Mexco exercisable at prices ranging from $6.06 to $6.29 per share. These options are exercisable at a price not less than the fair market value of the stock at the date of grant, have an exercise period of ten years and generally vest over four years.

Included in the following table is a summary of the grant-date fair value of stock options granted and the related assumptions used in the Binomial models for stock options granted in fiscal 2013, 2012 and 2011. All such amounts represent the weighted average amounts for each period.

No forfeiture rate is assumed for stock options granted to directors or employees due to the forfeiture rate history for these types of awards. There were no stock options forfeited or expired during the year ended March 31, 2013 and 2012. During the year ended March 31, 2011, 1,000 vested stock options expired because they were not exercised prior to the end of their ten-year term and 10,000 unvested stock options were forfeited due to the termination of a consulting agreement with a consultant and the resignation of an employee.

For the year ended March 31, 2013, employees and directors exercised options on a total of 3,750 shares at exercise prices of $4.35 per share.We received proceeds of $16,313 from these exercises. The total intrinsic value of the exercised options was $3,138. No tax deduction is recorded when options are awarded. Mexco issued new shares of common stock to settle these option exercises.For the year ended March 31, 2012, employees and directors exercised options on a total of 10,000 shares at exercise prices of $4.00 per share. We received proceeds of $40,000 from these exercises. The total intrinsic value of the exercised options was $38,600. For the year ended March 31, 2011, stock options covering 85,250 shares were exercised with 29,950 of these exercised options resulted in a disqualifying disposition. We received proceeds of $533,625 from these option exercises for the year ended March 31, 2011.
