Attached to these notes as additional consideration was 1,074,998 5-year warrants with a conversion price of the lower of 1.50 or 25% discount of the price per share of Common Stock offered in the Qualified Offering and also include a ratchet provision. Embedded derivatives are valued separately from the host instrument and are recognized as derivative liabilities in the Company’s balance sheet. The Company measures these instruments at their estimated fair value and recognizes changes in their estimated fair value in results of operations during the period of change. The Company has estimated the fair value of these embedded derivatives for convertible debentures and associated warrants using a multinomial lattice model as of January 31, 2021. The fair values of the derivative instruments are measured each quarter, which resulted in a loss of $3,433,938 and derivative expense of $4,630,288 during the nine months ended January 31, 2021. As of January 31, 2021, the fair market value of the derivatives aggregated $9,144,226, using the following assumptions: estimated 1.67-5.00-year term, estimated volatility of 86.74-104.01%, and a discount rate of 0.10-0.41%.
