Final answer:
The subsequent event that is least likely to result in an adjustment to the financial statements is material changes in the quoted market prices of listed investment securities.
Step-by-step explanation:
Out of the given subsequent events, the one that is least likely to result in an adjustment to the financial statements is material changes in the quoted market prices of listed investment securities since the balance sheet date. Unlike the other events, this event does not directly affect the realization of accounts receivable, inventories, or the settlement of liabilities as of the balance sheet date. However, it's important to note that changes in market prices may still have an impact on the value of the investment securities.
