Equity [Abstract] |
Stockholders' Deficit | NOTE 7 - STOCKHOLDERS’ DEFICIT Stock-Based Compensation In connection with the consummation of the Merger completed on February 12, 2016, we adopted Prior Protagenic’s 2006 Employee, Director and Consultant Stock Plan (the “2006 Plan”). On June 17, 2016, our stockholders adopted the 2016 Plan and, as a result, we terminated the 2006 Plan. We will not grant any further awards under the 2006 Plan. All outstanding grants under the 2006 Plan will continue in effect in accordance with the terms of the particular grant and the 2006 Plan. Pursuant to the 2016 Plan, the Company’s Compensation Committee may grant awards to any employee, officer, director, consultant, advisor or other individual service provider of the Company or any subsidiary. On each of January 1, 2017 and January 1, 2019, pursuant to an annual “evergreen” provision contained in the 2016 Plan, the number of shares reserved for future grants was increased by 564,378 shares, or a total of 1,693,134 shares. As a result of this increase, as of December 31, 2019, the aggregate number of shares of common stock available for awards under the 2016 Plan was 4,304,245 shares. Options issued under the 2016 Plan are exercisable for up to ten years from the date of issuance. There were 3,835,366 options outstanding as of December 31, 2019. The fair value of each stock option granted was estimated using the Black-Scholes assumptions and or factors as follows:
Exercise price |  | $ | 1.00 - $1.75 |
Expected dividend yield |  |  | 0 | %
Risk free interest rate |  |  | 2.09% - 2.70 | %
Expected life in years |  |  | 10 |
Expected volatility |  |  | 137% - 140 | %
There were 3,846,299 options outstanding as of December 31, 2018. The fair value of each stock option granted was estimated using the Black-Scholes assumptions and or factors as follows:
Exercise price |  | $ | 1.25 - $1.75 |
Expected dividend yield |  |  | 0 | %
Risk free interest rate |  |  | 2.73% - 2.85 | %
Expected life in years |  |  | 3.75-9.40 |
Expected volatility |  |  | 139% - 146 | %
