In October 2019, Meno Corp. announced a stock option incentive plan for its top executives. The plan provides each executive 7,200 stock options for Meno's common stock, $1 par, at an exercise price of $36 per share reduced by the percentage increase in EPS from December 31, 2019, to December 31, 2021. The rights are nontransferable and are exercisable three years after the grant date and prior to five years from the grant date. Continuing employment is required through exercise date, and the requisite service period ends on the first possible exercise date. On January 1, 2020, Martha Smith was granted 7,200 options when the market price was $30 per share. Using an option-pricing model, the fair value of the options granted to Smith was valued at $9 per option. On December 31, 2020, Meno's management believed that Smith would exercise her options at the first exercise date. By December 31, 2021, Meno's EPS had increased by 20%. Smith exercised her options on December 31, 2022, when the market price of the stock was $60 per share. a. Compute the total amount of compensation cost for the grant made to Smith. b.
