Note 10 — Fair Value Measurements

The following tables presents information about the Company’s financial assets and liabilities that are measured at fair value on a recurring basis as of September 30, 2021, by level within the fair value hierarchy:

Transfers to/from Levels 1, 2, and 3 are recognized at the beginning of the reporting period. The estimated fair value of the Public Warrants transferred from a Level 3 fair value measurement to a Level 1 fair value measurement, when the Public Warrants were separately listed and traded in March 2021. The estimated fair value of the Private Placement Warrants was transferred from a Level 3 measurement to a Level 2 fair value measurement in July 2021.

Level 1 instruments include investments in mutual funds invested in government securities. The Company uses inputs such as actual trade data, benchmark yields, quoted market prices from dealers or brokers, and other similar sources to determine the fair value of its investments.

Level 2 instruments include Private Placement Warrants. The Company uses the same quoted market prices from dealers or brokers, and other similar sources as Public Warrants to determine the fair value of its investments.

The fair value of the Public Warrants as of September 30, 2021, was measured utilizing the Level 1 input of the observable listed trading price for such warrants. Level 3 instruments are comprised of the Working Capital Loan measured at fair value using a Monte Carlo simulation model. The estimated fair value of the Working Capital Loan is determined using Level 3 inputs. Inherent in a Monte Carlo simulation model are assumptions related to expected stock-price volatility, expected life, risk-free interest rate and dividend yield. The Company estimates the volatility of its common stock warrants based on implied volatility from the Company’s traded warrants and from historical volatility of select peer company’s common stock that matches the expected remaining life of the warrants. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected remaining life of the warrants. The expected life of the warrants is assumed to be equivalent to their remaining contractual term. The dividend rate is based on the historical rate, which the Company anticipates remaining at zero.

The following table provides quantitative information regarding Level 3 fair value measurements inputs used by the estimated fair value of warrants that may be issued upon conversion of the promissory note – related party at their measurement dates:

The change in the fair value of the derivative warrant liabilities, measured using Level 3 inputs, for the three and nine months ended September 30, 2021 is summarized as follows:

The change in the fair value of the Promissory Note – related party measured with Level 3 inputs for the period for the nine months ended September 30, 2021, is summarized as follows:
