Stock Purchase Options | NOTE 7 – STOCK PURCHASE OPTIONS AND WARRANTS Stock Purchase Options On March 21, 2018, the Company’s Board of Directors voted to grant to sixteen individuals options to purchase up to an aggregate of 1,500,000 shares of the Company’s common stock. The terms of the options are as follows: the options vest one-third on the first anniversary of the date of grant; one-third on the second anniversary of the date of grant; and one-third on the third anniversary of the date of grant; the options have a contractual life of eight years from the date of grant; and the exercise price is $0.65, which was the market price of the options on the date of the grant. Included in the grants were options to purchase up to 250,000 shares to the Company’s President and Chief Executive Officer, and options to purchase up to 250,000 shares to the Company’s Chief Technical Officer. The options were not issued pursuant to a stock option or stock incentive plan. During the three months ended March 31, 2018, the Company had issued 1,500,000 options. As the holders of the Company’s outstanding options are employees and non-employees, the values attributable to non-employee options are re-measured on a quarterly basis and amortized over the service period and until they have fully vested over a 3-year vesting period. Stock options issued to employees are valued on the date of issuance and amortized over the service period until they have fully vested over a 3-year vesting period. The Company believes that the fair value of the stock options is more reliably measurable than the fair value of the services received. The fair value of the non-employee stock options granted was re-measured at each reporting date using the Black-Scholes valuation model. As of March 31, 2018, the Company re-measured the options at a value of $1,794,222 to be recognized over the vesting period, of which $540,169 has been recognized since inception. The Company recorded $71,891 of stock-based compensation expense in the three months ended March 31, 2018.
