       Stock Options The exercise price of each stock option equals or exceeds the fair market price of our stock on the date of grant. Options granted beginning in 2020 can generally be exercised over a term of ten years and prior to 2020 options could generally be exercised over a term of seven years. Stock options outstanding as of December 31, 2024, generally vest ratably over three years from the grant date. There were no stock options granted during the years ended December 31, 2024 and 2023. The fair value of each option award is estimated on the date of grant using the Black-Scholes option-pricing model and the weighted average assumptions as outlined in the following table:
