Fair Value Measurements

The carrying amounts of certain financial instruments, including cash and cash equivalents, prepaid expenses and other current assets, accounts payable, and accrued expenses approximate their respective fair values due to the short-term nature of such instruments.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The Company evaluates its financial assets and liabilities subject to fair value measurements on a recurring basis to determine the appropriate level in which to classify them for each reporting period, pursuant to the policy described in Note 2. This determination requires significant judgments to be made. The following table summarizes the conclusions reached as of December 31, 2020 and 2019 for financial instruments measured at fair value on a recurring basis (in thousands):

The Company measures cash equivalents at fair value on a recurring basis. The fair value of cash equivalents is determined based on “Level 1” inputs, which consist of quoted prices in active markets for identical assets.

 

Level 3 financial liabilities consist of the warrant liabilities for which there is no current market such that the determination of fair value requires significant judgment or estimation. Changes in fair value measurements categorized within Level 3 of the fair value hierarchy are analyzed each period based on changes in estimates or assumptions and recorded as appropriate. The Company uses the Black-Scholes option valuation model to value the Level 3 warrant liabilities at inception and on subsequent valuation dates. This model incorporates transaction details such as the Company’s stock price, contractual terms, maturity, risk free rates, as well as volatility.  The unobservable input for all of the Level 3 warrant liabilities includes volatility.  The historical volatility of the Company, using its closing common stock prices, is utilized to reflect future volatility over the expected term of the warrants.  At December 31, 2020, the range and weighted average of the Level 3 volatilities utilized in the Black-Scholes model to fair value the warrant liabilities were 71.8% to 86.6% and 78.0%, respectively.  Additionally, the expected term associated with the December 2019 Public Offering warrants is an unobservable input given that the expiration of the warrants is the earlier of (i) such date that is six months after the Company publicly announces the approval from the U.S. Food and Drug Administration for ibrexafungerp for the treatment of vulvovaginal candidiasis and (ii) June 12, 2023.  The Company utilized a probability assessment to estimate the likelihood of occurrence for the two potential expiration dates and allocated the probability of occurrence percentage to the fair values calculated based on the two potential expected terms.  The weighted average expected term is 1.2 years as of December 31, 2020 for the December 2019 Public Offering warrants with a range of 0.9 to 2.5 years.   

 

The Company uses the binomial lattice valuation model to value the Level 3 derivative liabilities at inception and on subsequent valuation dates.  This model incorporates transaction details such as the Company’s stock price, contractual terms, dividend yield, risk-free rate, historical volatility, credit rating, market credit spread, and estimated effective yield.  The unobservable inputs associated with the Level 3 derivative liabilities are adjusted equity volatility, market credit spread, and estimated yield.  As of December 31, 2020, these inputs were 58.1%, 1,458 basis points, and 14.9%, respectively.  The range of volatilities were 56.5% to 60.1%.  The senior convertible notes are initially fair valued using the binomial lattice model and

with the straight debt fair value calculated using the discounted cash flow method.  The discount for lack of marketability, 7.0% as of December 31, 2020, is applied to the value of the March 2019 Notes.  The residual difference represents the fair value of the embedded derivative liabilities and the fair value of the embedded derivative liabilities are reassessed using the binomial lattice valuation model on a quarterly basis.  

 

A reconciliation of the beginning and ending balances for liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) is as follows (in thousands):
