Answer:
$280,000
Step-by-step explanation:
Fair value = $4
Options granted = 210,000 shares
Total compensation = Fair value*Options granted
Total compensation = $4 * 210,000
Total compensation = $840,000
Number of years = 3
Compensation per year = Total compensation / Number of years
Compensation per year = $840,000 / 3
Compensation per year = $280,000
