Warrants Classified as Liabilities

 

Liability-classified warrants consist of warrants issued by Biozone in connection with equity financings in October 2013 and January 2014, which were assumed by the Company in connection with its merger with Biozone in January 2014. Warrants accounted for as liabilities have the potential to be settled in cash or are not indexed to the Company’s own stock.

 

The estimated fair value of outstanding warrants accounted for as liabilities is determined at each balance sheet date. Any decrease or increase in the estimated fair value of the warrant liability since the most recent balance sheet date is recorded in the condensed consolidated statement of operations as changes in fair value of derivative liabilities.

 

The fair value of the warrants classified as liabilities is estimated using the Black-Scholes option-pricing model with the following inputs as of June 30, 2021:

 

   October 2013
Warrants
   January 2014
Warrants
 
         
Strike price  $15.00   $15.00 
Expected dividend yield   0.00%   0.00%
Contractual term (years)   2.3    2.5 
Cumulative volatility   129.03%   125.81%
Risk-free rate   0.11%   0.13%
Value  $0.30   $0.32 

 

The fair value of the warrants classified as liabilities is estimated using the Black-Scholes option-pricing model with the following inputs as of December 31, 2020:

 

   October 2013
Warrants
   January 2014
Warrants
 
         
Strike price  $15.00   $15.00 
Expected dividend yield   0.00%   0.00%
Contractual term (years)   2.8    3.0 
Cumulative volatility   119.18%   116.65%
Risk-free rate   0.16%   0.18%
Value  $0.36   $0.38 

 

The Company estimates volatility using a blend of its own historical stock price volatility as well as that of market comparable entities since the Company’s common stock has limited trading history and limited observable volatility of its own. The expected life assumption is based on the remaining contractual terms of the warrants. The risk-free rate is based on the zero-coupon rates in effect at the balance sheet date. The dividend yield used in the pricing model is zero, because the Company has no present intention to pay cash dividends.
