Options
There were no options granted during the three months ended March 31, 2023. The fair value of each employee and non-employee stock option award was estimated on the date of grant for each option using the Black-Scholes option pricing model. The group uses the following key assumptions to determine the grant date fair value of options in the period they were granted as follows:

Fair Value of Underlying Stock

The fair value of the Company’s Class A ordinary shares is determined by the closing price, on the date before the grant, of the Class A ordinary shares, which are traded on the NYSE. Prior to the Merger described in the 2022 Form 10-K, the estimated fair value of the Class A ordinary shares had been determined by the board of directors as of the date of each grant, with input from management, considering the most recently available third-party valuations of the Group’s Class A ordinary shares, and the assessment of additional objective and subjective factors that they believed were relevant and which may have changed from the date of the most recent valuation through the date of the grant.

Volatility

The Company uses an average historical stock price volatility of a peer group of comparable publicly traded healthcare companies representative of our expected future stock price volatility, as there is not sufficient trading history for our Class A ordinary shares. For purposes of identifying these peer companies, the Company considers the industry, stage of development, size and financial leverage of potential comparable companies. For each grant, the Company measures historical volatility over a period equivalent to the expected term.

Risk-Free Interest Rate

The risk-free interest rate is based on the implied yield currently available on U.S. Treasury zero-coupon issues with maturities similar to the expected term of the award.

Expected Dividend Yield

The Company has not paid and does not anticipate paying any dividends in the foreseeable future. Accordingly, the Company estimates the dividend yield to be zero.

Expected Term

The Company determines the expected term of awards using the simplified method which is used when there is insufficient historical data about exercise patterns and post-vesting employment termination behavior. The simplified method is based on the vesting period and the contractual term for each grant. The mid-point between the vesting date and the maximum contractual expiration date is used as the expected term under this method.
