The option price was set at $30, and the fair value option-pricing model determines the total compensation expense to be $508,500. All of the options were exercised during the year 2023: 22,600 on January 3 when the market price was $65, and 11,300 on May 1 when the market price was $74 a share. Prepare journal entries relating to the stock option plan for the years 2021, 2022, and 2023. Assume that the employee performs services equally in 2022 and 2023.
