NOTE 10 – DERIVATIVE FINANCIAL INSTRUMENTS

The Company has identified the embedded derivatives related to the convertible notes described in Notes 8 and 9. These embedded derivatives included certain conversion and reset features. The accounting treatment of derivative financial instruments requires that the Company record fair value of these derivative liabilities as of the issuance date of the convertible notes and each subsequent reporting date as well as upon modification, repayment, or extinguishment of the convertible notes. Derivative liabilities are eliminated upon repayment or extinguishment of the convertible notes and recorded as an adjustment to additional paid in capital.

The Company estimates the fair value of these derivative liabilities using the Black-Scholes valuation model. The initial value is used in the determination of a note discount with each subsequent change in fair value as a component of operations. The range of fair value assumptions used for derivative financial instruments during the year ended December 31, 2020, were as follows:

The expected dividend yield is zero, because the Company does not anticipate paying a dividend within the relevant timeframe. The risk-free interest rate used is based on the U.S. Treasury constant maturity rate in effect at the time of valuation for the expected term of the derivative liabilities to be valued. The expected volatility is calculated based on the historical volatility of the Company.

The Company recognized derivative liabilities for the years ended December 31, 2020 and 2019, as follows:
