Answer:
Payoff per share = $4
Profot pershare = $2
Explanation:
In a call option, the long (the party that buy the put) will have gain on the option when the underlying asset price is higher than the excercise price of that asset (imagine the advantage that you can buy an apple at $10 when its market price is $12). Because the stock price is $44, higher than exercise price of 40, so the company should exercise the call. Total payoff per share is 44 - 40 = $4 (and profit per share = 4 - 2 = $2) .
Note: We dont include premium to buy the call here because the question asking about payoff. We on include premium in calculations when the question is about profit.
