Warrants and Derivative Liabilities Warrants and Derivative Liabilities
There are significant judgements and estimates inherent in the determination of the fair value of the Company’s warrants and derivative liabilities. These judgements and estimates include assumptions regarding the Company’s future operating performance, the time to completing a liquidity event, if applicable, and the determination of the appropriate valuation methods. If the Company had made different assumptions, the fair value of the warrants and derivative liabilities could have been significantly different (See Note 2).

Emerald Financing Warrant Liability
The Emerald Financing Warrants were issued during 2018 in connection with the Emerald Financing, and originally contained a price protection feature. In connection with the August 2020 Financing, the exercise price was permanently set to $0.10. The warrants contain a contingent put option if the Company undergoes a subsequent financing that results in a change in control. The warrant holders also have the right to participate in certain subsequent financing transactions on an as-if converted basis.
The Company reviewed the warrants for liability or equity classification under the guidance of ASC 480-10, Distinguishing Liabilities from Equity, and concluded that the warrants should be classified as a liability and re-measured to fair value at the end of each reporting period. The Company also reviewed the warrants under ASC 815, Derivatives and Hedging/Contracts in Entity’s Own Equity, and determined that the warrants also meet the definition of a derivative. With the assistance of a third party valuation specialist, the Company valued the warrant liabilities utilizing the Monte Carlo valuation method pursuant to the accounting guidance of ASC 820-10, Fair Value Measurements. Beginning March 31 2021, the Company changed its valuation model for the Emerald Financing Warrant Liability to a Black-Scholes valuation method, as it was determined that a more simplistic model such as the Black-Scholes valuation method yields a substantially similar result as a Monte Carlo simulation due to the Company's current assumptions.
The warrant liability is valued at the balance sheet dates using the following assumptions:
