. Derivative Liabilities
The investor and placement agent warrants, issued in connection with a registered direct offering in September 2016, contained a provision for net cash settlement in the event that there is a fundamental transaction (contractually defined as a merger, sale of substantially all assets, tender offer or share exchange, whereby such other Person or group acquires more than 50% of the outstanding common stock). If a fundamental transaction occurs in which the consideration issued consists principally of cash or stock in a successor entity, then the warrant holder has the option to receive cash equal to the fair value of the remaining unexercised portion of the warrant. Due to this contingent cash settlement provision, the investor and placement agent warrants require liability classification as derivatives in accordance with ASC 480,
Distinguishing Liabilities from Equity
, and ASC 815,
Derivatives and Hedging,
and are recorded at fair value. All of the investors and placement agent warrants were exercised during the fiscal year ending May 31, 2020.
The following tables summarize the fair value of the warrant derivative liability and related common shares as of inception date September 15, 2016, prior fiscal year end date May 31, 2020 and current reporting date November 30, 2020 (in thousands):

Changes in the fair value of the derivative liability are reported as “Change in fair value of derivative liability” in the Consolidated Statements of Operations. The Company recognized approximately $0.3  million of
non-cash
gain, due to the changes in the fair value of the liability associated with such classified warrants during the six months ended November 30, 2019.
ASC 820,
Fair Value Measurement
, provides requirements for disclosure of liabilities that are measured at fair value on a recurring basis in periods subsequent to the initial recognition. Fair values for the warrants were determined using a Binomial Lattice valuation model.

The Company estimated the fair value of the warrant derivative liability as of inception date September 15, 2016, May 31, 2019 and November 30, 2019, using the following assumptions:

Fair value of underlying stock

Expected term (in years)
     5       2.29       1.79  
Stock price volatility
     106     61     63
Expected dividend yield
     —         —         —    
Probability of fundamental transaction
     50     50     50
Probability of holder requesting cash payment
     50     50     50
Due to the fundamental transaction provision contained in the warrants, which could provide for early redemption of the warrants, the model also considered subjective assumptions related to the fundamental transaction provision. The fair value of the warrants will be significantly influenced by the fair value of the Company’s stock price, stock price volatility, changes in interest rates and management’s assumptions related to the fundamental transaction provisions.
As described in Note
5
above, the redemption provision embedded in the June 2018 and January 2019 Notes required bifurcation and measurement at fair value as a derivative. The fair value of the Note redemption provision derivative liabilities was calculated using a Monte Carlo Simulation which uses randomly generated stock-price paths obtained through a Geometric Brownian Motion stock price simulation. The fair value of the redemption provision will be significantly influenced by the fair value of the Company’s stock price, stock price volatility, changes in interest rates and management’s assumptions related to the redemption factor.
 
The Company estimated the fair value of the redemptive provision using the following assumptions on the closing date of November 15, 2018, January 30, 2019 and November 30, 2019:

As discussed above, the June 2018 and January 2019 Notes were fully satisfied during the fiscal year ended May 31, 2020 and there is no outstanding balance as of November 30, 2020.

The Company recognized approximately $0.6 million of
non-cash
gain, due to the changes in the fair value of the liability associated with such classified redemption provision for the six months ended November 30, 2019. There was no gain or loss for the six months ended November 30, 2020
, as the notes were previously retired.
