NOTE 10 – WARRANTS
The following is a summary of the Company’s warrant activity:
The Company estimates the fair value of warrants granted on each grant date using the Black-Scholes option valuation model. The expected volatility is calculated based on the historical volatility of the Company. The risk-free interest rate used is based on the U.S. Treasury constant maturity rate in effect at the time of grant for the expected term of the warrants to be valued. The expected dividend yield is zero, because the Company does not anticipate paying a dividend within the relevant timeframe. Due to a lack of historical information needed to estimate the Company’s expected term, it is estimated using the simplified method allowed.
The Company did not recognize any stock-based compensation expense related to warrants during the nine-months ended September 30, 2018 and 2017, respectively.
During the year ended December 31, 2017, the Company issued 233,217 shares of common stock in connection with the cashless exercise of a warrant for 298,000 shares of common stock at $0.10 per share with 64,783 shares of common stock withheld with an aggregate fair market value equal to the aggregate exercise price.
During the year ended December 31, 2017, the Company issued 500,000 shares of common stock in connection with the exercise of a warrant for 500,000 shares of common stock at $0.08 per share in exchange for $40,000.
During the year ended December 31, 2017, warrants to purchase an aggregate of 392,047 shares of restricted common stock expired.
In June 2018, the Company commenced an offering to exchange outstanding warrants for shares of common stock under a Form S-4 Registration Statement. These shares of common stock would be issued to warrant holders in exchange for (i) their outstanding warrants to purchase shares of common stock at $0.625 per share, and (ii) cash payment of $0.15 per share. This offering closed on July 27, 2018, and resulted in an exchange of 9.6 million warrants for $1,440,043 in gross proceeds and 9,600,286 shares of common stock. Of this amount, $653,278 was held in escrow as subscriptions receivable as of September 30, 2018. The subscriptions receivable amount was received on October 5, 2018, less $113,616 in placement fees and expenses, to net $539,662. As part of this exchange, warrants to purchase 315,010 shares of common stock at $0.21 per share were issued to investment bankers for their services.
