Final answer:
If the predecessor's report was unqualified, the successor should issue an unqualified opinion on the current year's financial statements.
Step-by-step explanation:
If the predecessor's report was unqualified, the successor should issue an unqualified opinion on the current year's financial statements. This is because an unqualified opinion means that the financial statements are presented fairly and are in accordance with generally accepted accounting principles (GAAP). As the successor auditor, there is no indication of any material misstatements or issues with the financial statements, so an unqualified opinion would be appropriate.
