Weighted average assumptions
The fair value of stock options granted to employees, excluding stock options that contain market conditions, was estimated at the dates of grant using the Black-Scholes option-pricing model with the following weighted average assumptions:
20222021
Expected volatility47.25 %45.55 %
Risk-free interest rate1.04 %0.38 %
Expected option life4.07 years4.27 years
Expected dividend yield%%
Forfeiture rate27.07 %28.51 %
The fair value of stock options granted to employees with vesting dependent on market conditions tied to the Company's future share price performance is measured using the Monte Carlo pricing model to estimate the Company's potential future share price. This model leverages assumptions that the expected volatility of the share price is 41% and the expected option life is 7 years.
