Fair Value Measurements |
Fair Value Measurements | (3) Fair Value Measurements ASC 820, Fair Value Measurements, provides guidance on the development and disclosure of fair value measurements. The Company follows this guidance for fair value measurements, which defines fair value, establishes a framework for measuring fair value under U.S. GAAP, and expands disclosures about fair value measurements. The guidance requires fair value measurements be classified and disclosed in one of the following three categories:
| ● | Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for identical assets or liabilities.
| ● | Level 2: Observable prices that are based on inputs not quoted on active markets but corroborated by market data.
| ● | Level 3: Unobservable inputs which are supported by little or no market activity and values determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant judgment or estimation.
Fair value measurements discussed herein are based upon certain market assumptions and pertinent information available to management as of June 30, 2021, and December 31, 2020. The carrying amount of cash and accounts payable approximated fair value as they are short term in nature. The guidance in ASC 815, Derivatives and Hedging, requires that we mark the value of our common stock warrant liability to market and recognize the change in valuation in our statements of operations each reporting period. Determining the warrant liability to be recorded requires us to develop estimates to be used in calculating the fair value of the warrant. The fair value of the common stock warrants we issued were estimated based on a Black-Scholes model as of June 30, 2021, and December 31, 2020. The estimated fair value of the warrant liability and the derivative liability (“embedded put features”) included in the convertible promissory notes represent Level 3 measurements. The following table details the fair value measurement within the fair value hierarchy of the Company’s financial instruments, which includes the Level 3 liabilities: ​
