Derivative Liability |
Derivative Liability | Note 7 – Derivative Liability Under authoritative guidance used by the FASB on determining whether an instrument (or embedded feature) is indexed to an entity’s own stock, instruments that do not have fixed settlement provisions are deemed to be derivative instruments. The Company has issued certain warrants that included a fundamental transaction provision that could give rise to an obligation to pay cash to the warrant holder. As a result, the warrants are classified as liabilities and are bifurcated from the debt host and accounted for as a derivative liability in accordance with ASC 815 and will be re-measured at the end of every reporting period with the change in value reported in the statement of operations. The derivative liabilities were valued using a Binomial pricing model with the following average assumptions: Schedule of Derivative Liabilities Assumptions
|  | December 31, 2021 |  |  | December 31, 2020 |
Risk-free interest rate |  |  | 1.26 | % |  |  | 0.36 | %
Expected volatility |  |  | 129 | % |  |  | 135 | %
Expected life (in years) |  |  | 3.6 years |  |  |  | 4.60 years |
Expected dividend yield |  |  | - |  |  |  | - |
Fair Value |  |  |  |  |  |  |  |
Warrants |  | $ | 138,000 |  |  | $ | 383,000 |
The risk-free interest rate was based on rates established by the Federal Reserve Bank. The Company uses the historical volatility of its common stock to estimate the future volatility for its common stock. The expected life of the derivative securities was determined by the remaining contractual life of the derivative instrument. For derivative instruments that already matured, the Company used the estimated life. The expected dividend yield was based on the fact that the Company has not paid dividends to its common stockholders in the past and does not expect to pay dividends to its common stockholders in the future. During 2021, 2,826 warrants were exercised which resulted in an extinguishment of derivative liability charge of $0.03 million. The Company recognized a net gain of $0.21 million and a loss of $0.23 million for the years ended December 31, 2021 and 2020, respectively, to account for the change in fair value of the derivative liability.
