Warrants
There are significant judgments and estimates inherent in the determination of the fair value of the Company’s warrants and derivative liabilities. These judgments 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).
Warrants vested and outstanding as of December 31, 2021 are summarized as follows:

Emerald Financing Warrant Liability (1)
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 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 liabilities were valued at the balance sheet dates using the following assumptions:

Emerald Multi-Draw Credit Agreement Compound Derivative Liability (2)
In connection with the advances under the Credit Agreement (See Note 4), the Company bifurcated a compound derivative liability related to a contingent interest feature and acceleration upon default provision (contingent put option) provided to Sciences. The Company’s estimate of fair value of the compound derivative liability was determined by using a differential cash flows valuation model, wherein the fair value of the underlying debt facility and its conversion right are estimated both with and without the presence of the contingent interest feature, holding all other assumptions constant. The resulting difference between the estimated fair values in both scenarios is the estimated fair value of the compound derivative. The fair value of the underlying debt facility was estimated by calculating the expected cash flows with consideration of the estimated probability of a change in control transaction, defined as an event of default by the agreement, and applying the expected default interest rate from the date of such default through maturity. The expected cash flows are then discounted back to the reporting date using a benchmark market yield. The conversion right component of the compound derivative was measured using a standard Black-Scholes Option Pricing model for each payment period.
On April 29, 2020, the Company entered into the Amended Credit Agreement which removed the change in control provision as an event of default for advances before and after the amendment. As a result of the modification, the contingent interest feature component of the compound derivative is no longer required to be bifurcated as a derivative liability. During the year ended December 31, 2020, the liability was reduced to $0 through an adjustment to the change in fair value of derivative liabilities.
Because Sciences would forgo the contingent interest if the contingent put option was exercised upon an event of default, the value ascribed to the contingent put option within the compound derivative is considered de minimis before and after the amendment to the Credit Agreement.
Series B Warrant Liability (3)
During the year ended December 31, 2020, 312,500 Series B Common Stock Warrants with an intrinsic value of $26,563 were exercised for no consideration per share, which resulted in the issuance of 312,500 shares of common stock. Prior to exercise, these Series B Warrants were adjusted to fair value using a Black-Scholes valuation method which considered the closing trading price on the exercise dates. Because the exercise price of these options had been reset to $0.00, the fair value derived from the valuation model approximated the market value of the Company’s common stock on the exercise dates. The warrants required liability classification because of certain cash redemption rights upon the occurrence of certain fundamental transactions, as defined in the Series B Common Stock Warrant agreements.
