On the date of the Transactions, the fair value of the Public Warrants and the Private Placement Warrants was estimated using a Monte Carlo simulation model. The fair value of the Public Warrants was subsequently measured based on the listed market price of such warrants at the end of the reporting period. The fair value of the Private Placement Warrants was subsequently estimated using a Monte Carlo simulation model at the end of the reporting period. The Company estimates the fair value of the warrants at each reporting period, with changes in fair value recognized in the consolidated statements of operations.
The estimated fair value of the warrant liabilities – Public Warrants is determined using Level 1 inputs. The estimated fair value of the warrant liabilities – Private Placement Warrants is determined using Level 3 inputs. Inherent in a Monte Carlo simulation are assumptions related to expected stock-price volatility, expected life and risk-free interest rate. The Company estimates the volatility of its ordinary shares based on historical volatility of select peer companies 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.

To derive the fair value of the Class B Units, we estimated the fair value of Class B Units using a valuation technique. For more information regarding the valuation of the Class B Units, see Note 11, Stock-Based Compensation. As more fully described in Note 1, we completed our Transactions in July 2021, and all Class B Units fully vested as of the transaction date, and the original operating agreement was terminated and replaced by a new operating agreement consistent with the Company’s Up-C structure. This new operating agreement does not contain the put and call options that existed under the previous operating agreement, and the Common Units under the new operating agreement are treated as common equity and do not generate stock-based compensation expense. The Class B Units liability was reclassified to equity as of the transaction date.
