Stock Incentive Plan and Stock Option Grants to Employees and Directors

On March 13, 2012, the Company adopted the Ë¿¹ÏÊÓƵ. 2012 Equity Incentive Plan (the “2012 Plan”) that provides for the grant of 3,500,000 shares in the form of incentive stock options, non-qualified stock options, restricted shares, stock appreciation rights and restricted stock units to employees, consultants, officers and directors. As of January 31, 2019, there were no shares remaining available for future issuance under the 2019 Plan. Ìý

On December 13, 2018, the stockholders of the Company approved the “Plan” that provides for the grant of 500,000 shares in the form of incentive stock options, non-qualified stock options, restricted shares, stock appreciation rights and restricted stock units to employees, consultants, officers and directors. As of January 31, 2019, there were approximately 65,000 shares remaining available for future issuance under the Plan.

The Company estimates the fair value of share-based compensation utilizing the Black-Scholes option pricing model, which is dependent upon several variables such as the expected option term, expected volatility of the CompanyÂ’s stock price over the expected term, expected risk-free interest rate over the expected option term, expected dividend yield rate over the expected option term, and an estimate of expected forfeiture rates. The Company believes this valuation methodology is appropriate for estimating the fair value of stock options granted to employees and directors which are subject to ASC Topic 718 requirements. These amounts are estimates and thus may not be reflective of actual future results, nor amounts ultimately realized by recipients of these grants. The Company recognizes compensation on a straight-line basis over the requisite service period for each award. The following table summarizes the assumptions the Company utilized to record compensation expense for stock options granted to employees during the period ended.

The Company utilized the simplified method to estimate the expected life for stock options granted to employees. The simplified method was used as the Company does not have sufficient historical data regarding stock option exercises. The expected volatility is based on historical volatility. The risk-free interest rate is based on the U.S. Treasury yields with terms equivalent to the expected life of the related option at the time of the grant. Dividend yield is based on historical trends. While the Company believes these estimates are reasonable, the compensation expense recorded would increase if the expected life was increased, a higher expected volatility was used, or if the expected dividend yield increased.
