Stock Options

As of January 31, 2016, the Company had outstanding stock options held by its directors, officers and an employee that were issued pursuant to compensation and director agreements.

The Company has adopted the provisions of ASC 718, “Compensation-Stock,” which requires the measurement and recognition of compensation expense for all stock-based awards made to employees.

The fair value of the stock options at the date of grant was estimated using the Black-Scholes option-pricing model.

The Company’s computation of expected volatility is based on the historical daily volatility of its publicly traded stock. For stock option grants issued during the periods ended January 31, 2016 and 2015, the Company used a calculated volatility for each grant. The Company lacks adequate information about the exercise behavior at this time and has determined the expected term assumption under the simplified method provided for under ASC 718, which averages the contractual term of the Company’s stock options of five years with the average vesting term of two and one sixth years for an average of two and two third years. The dividend yield assumption of zero is based upon the fact the Company has never paid cash dividends and presently has no intention of paying cash dividends. The risk-free interest rate used for each grant is equal to the U.S. Treasury rates in effect at the time of the grant for instruments with a similar expected life. No amounts relating to employee stock-based compensation have been capitalized.

Presented below is the Company’s stock option activity for employees and directors:
