For the year ended December 31, 2024, the Company used risk-free rates, estimated common stock volatility, expected term, and dividend yield as inputs and the fair value of the Company's common stock as a key input to estimate the grant date fair value using the Black-Scholes method. The Company does not assume dividend payments, as it does not pay dividends, and estimates common stock volatilities using the average historical volatility of a peer group of companies for the period immediately preceding the option grant for a term that is approximately equal to the option's expected term. The Company estimates the grant-date fair value of awards using the contractual term of award, if any, including discounts for applicable post-vesting restrictions such as remaining in the service to the business except as otherwise amended estimated using Black-Scholes method.
