Final answer:
The entry to adjust the stock investment portfolio to fair value will include a debit to the portfolio account and a credit to the unrealized gain account.
Step-by-step explanation:
To adjust the stock investment portfolio to fair value, the entry will include a debit to the portfolio account and a credit to the unrealized gain account.
In this case, the portfolio account has a general ledger balance of $319,500, below the actual fair value of $327,200. Therefore, the entry to adjust the portfolio to fair value will be:
Debit Portfolio Account: $7,700
Credit Unrealized Gain Account: $7,700
