Option pricing and models require the input of various assumptions, including the option’s expected life, expected dividend yield, price volatility and risk-free interest rate of the underlying stock. Forfeitures are recognized and accounted for as they occur.The calculation was based on the following assumptions: Year Ended December 31,20242023Weighted average grant date fair value (per share)$1.41$6.83Risk-free interest rate4.13% - 4.47%3.42% - 4.67%Expected volatility88.29% - 91.46%89.94% - 101.49%Expected term (in years)5.0 - 6.15.2 - 6.1Expected dividend yield——The Company determines the assumptions used in the option pricing model in the following manner:Risk-Free Interest Rate – For the determination of the risk-free interest rates, the Company utilizes the U.S. Treasury yield curve for instruments in effect at the time of measurement with a term commensurate with the expected term assumption.Expected Volatility – The Company based its estimate of expected volatility on a weighted average using the Company's limited historical stock price volatility data, supplemented with the estimated and expected volatilities of a guideline group of publicly traded companies. For these analyses, the Company selected companies with comparable characteristics including enterprise value, risk profiles, and with historical share price information sufficient to meet the expected life of the share-based awards. The Company computes the historical volatility data using the daily closing prices for the selected companies’ shares during the equivalent period of the calculated expected term of its share-based awards. The Company will continue to apply this process until a sufficient amount of historical information regarding the volatility of its own stock price becomes available.
