Final answer:
The question pertains to the financial accounting of a call option contract from its purchase to its settlement, including the journal entries required for the changes in the option's value and its settlement.
Step-by-step explanation:
The question focuses on the accounting treatment of a call option contract. When Mills Corp purchased the call option on shares of XYZ stock on January 1, 2025, it made an investment and incurred an expense.
Correspondingly, an asset account "Investment in Call Option" would be debited with the total cost of the option contract, and a cash or cash equivalent account would be credited. No further entries would be required until the value change needs to be recorded or the option is exercised or expires.
By March 31, 2025, XYZ's stock price increased, and the time value of the contract was appraised at $90. This would lead to an adjustment journal entry recognizing the increase in fair value of the call option. The difference between the initial value and this new appraisal must be recorded as either an unrealized gain or an increase in the asset's value.
The settlement of the option in April, when Mills Corp decided to exercise the option or sell it due to increase in the underlying stock's price, would involve the final fair value appraisal and the actual gains realized from the transaction.
