The fair values of government money market funds have been measured on a recurring basis using Level 1 inputs, which are based on unadjusted quoted market prices within active markets. The investments in securities, including investments in fixed income securities, have been measured using quoted pricing on active markets for Level 1 investments and inputs based on alternative pricing sources and models utilizing observable market inputs for Level 2 investments.
The fair value of the Public Warrants is classified as Level 1 due to the use of an observable market quote in an active market. The fair value of the Private Placement Warrants is classified as Level 2 due to the use of an observable market quote for the Public Warrants, which are considered to be a similar asset in an active market. The warrant liability is calculated by multiplying the quoted market price of the Company’s Public Warrants by the total number of Public Warrants and Private Placement Warrants.
The Company’s Level 3 liability consists of the Series A Penny Warrants associated with the issuance of Series A Preferred Stock and Series B Preferred Stock. This liability has been classified as Level 3 due to the use of unobservable inputs within the valuation, namely volatility.
The fair value of the Series A Penny Warrant liability as of March 4, 2024 and December 31, 2024 was determined utilizing a Monte Carlo simulation valuation method, using the following inputs and assumptions:
