|Share-based Payment Arrangement [Abstract]|
Note 11 - Stock Options
In September 2011, the Company adopted the 2011 Employee Stock Incentive Plan (the "2011 Plan") which provides for the granting of incentive and non-statutory common stock options and stock based incentive awards to employees, non-employee directors, consultants and independent contractors. The plan was amended and restated in May 2014. Unless terminated sooner by the Board of Directors, this plan will terminate on August 31, 2021.
In February 2018, the Company adopted the 2018 Employee Stock Incentive Plan (the "2018 Plan" and together with the 2011 Plan, the "Option Plans"), which is utilized with the 2011 Plan for employees, corporate officers, directors, consultants and other key persons employed. The 2018 Plan provides for the granting of incentive stock options, NQSOs, stock grants and other stock-based awards, including Restricted Stock and Restricted Stock Units (as defined in the 2018 Plan).
Incentive stock options granted under the Option Plans are granted at exercise prices not less than 100% of the estimated fair market value of the underlying common stock at date of grant. The exercise price per share for incentive stock options may not be less than 110% of the estimated fair value of the underlying common stock on the grant date for any individual possessing more that 10% of the total outstanding common stock of the Company. Options granted under the Option Plans vest over periods ranging from immediately to four years and are exercisable over periods not exceeding ten years.
The aggregate number of shares that may be awarded under the 2011 Plan as of June 30, 2019 is 158,424 and awarded under the 2018 Plan as of June 30, 2019 is 6,316,376. As of June 30, 2019, 4,912,662 of options were granted to employees, directors and consultants of the Company (including 39 shares outside of our Options Plans) and 1,562,177 shares of common stock were reserved for future issuance under the Option Plans.
During the three months ended March 31, 2019, the Company granted stock options for the purchase of 2,717,500 shares of common stock to employees and directors of the Company. These stock options are either 100% vested or vest pro-rata over 12 to 48 months, have a life of ten years and an exercise price of $2.26 per share. The Company valued the stock options using the Black-Scholes option valuation model and the fair value of the awards was determined to be $3.3 million. The fair value of the common stock as of the grant date was determined to be $2.26 per share.
During the three months ended June 30, 2019, the Company granted stock options for the purchase of 2,337,500 shares of common stock to employees and directors of the Company. These stock options vest pro-rata over 12 to 48 months, have a life of ten years and an exercise price of $0.75 per share. The Company valued the stock options using the Black-Scholes option valuation model and the fair value of the awards was determined to be $928,000. The fair value of the common stock as of the grant date was determined to be $0.75 per share.
The Company recorded a stock based compensation charge for the amortization of employee stock options of $858,000 and $571,000 for the three months ended June 30, 2019 and 2018, respectively, and $1,506,000 and $777,000, for the six months ended June 30, 2019 and 2018, respectively.
As of June 30, 2019, the fair value of non-vested stock options totaled $3.1 million, which will be amortized to expense over the weighted average remaining term of 0.56 years.
The fair value of each employee stock option grant is estimated on the date of the grant using the Black-Scholes option-pricing model. Key weighted-average assumptions used to apply this pricing model during the six months ended June 30, 2019 were as follows:
The expected stock price volatility for the Company's stock options was determined by the historical volatilities for industry peers and used an average of those volatilities. The Company attributes the value of stock-based compensation to operations on the straight-line single option method. Risk free interest rates were obtained from U.S. Treasury rates for the applicable periods. The dividends assumptions was $0 as the Company historically has not declared any dividends and does not expect to.
