Final answer:
To determine the total compensation cost pertaining to the incentive stock option plan, multiply the number of options granted by the fair value of the options. To record compensation expense on December 31, 2024, multiply the number of options granted by the fair value of the options and divide by the vesting period. The same calculation can be used to record compensation expense on December 31, 2025.
Step-by-step explanation:
The total compensation cost pertaining to the incentive stock option plan can be calculated by multiplying the number of options granted (80 million) by the fair value of the options ($1 per option).
Compensation expense on December 31, 2024, can be recorded by multiplying the number of options granted (80 million) by the fair value of the options ($1 per option) and dividing it by the vesting period.
Compensation expense on December 31, 2025, can be recorded using the same calculation as in 2.
When 75% of the options are exercised on March 12, 2026, the compensation expense will be recorded by multiplying the number of options exercised (75% of 80 million) by the difference between the market price of the stock on the exercise date ($8) and the exercise price ($7).
The expiration of options does not require any recording of compensation expense.
