Final answer:
The CPA's next course of action would be to issue a revised auditor's report and distribute it to each creditor known to be relying on the financial statements.
Step-by-step explanation:
The CPA's next course of action most likely would be to issue a revised auditor's report and distribute it to each creditor known to be relying on the financial statements.
In this scenario, the CPA learned about a subsequent event that had a material impact on the financial statements after issuing the unqualified opinion. Even though management refused to adjust the financial statements, the CPA has determined that the information is reliable and there are creditors relying on the financial statements. Therefore, the most appropriate action for the CPA is to issue a revised auditor's report to inform the creditors about the new information.
This ensures that the creditors are provided with updated and accurate information, allowing them to make informed decisions based on the revised financial statements.
