11 (103) (Issuance and Exercise of Share Options) On November 1, 2018, Olympic plc adopted chare-option plan that granted options to key executives to purchase 40,000 shares of the company's C10 par value ordinary shares. The options were granted on January 2, 2019, and were vested 2 years after the date of grant if the grantee was still an employee of the company. The options expired 6 years from date of grant. The option price was set at 40, and the fair value option-pricing model determines the total compensation expense to be 600,000. All of the options were exercised during the year 2021: 30,000 on January 3 when the market price was 67, and 10,000 on May 1 when the market price was 77 a share. Instructions Prepare journal entries relating to the share-option plan for the years 2019, 2020, and 2021. Assume that the employees perform services equally in 2019 and 2020
