The following are independent situations for which you will recommend an appropriate audit report on internal control over financial reporting as required by PCAOB auditing standards:
1. The auditor identified a material misstatement in the financial statements that was not detected by management of the company.
2. The auditor was unable to obtain any evidence about the operating effectiveness of internal control over financial reporting.
3. The auditor determined that a deficiency in internal control exists that will not prevent or detect a material misstatement in the financial statements.
4. During interim testing, the auditor identified and communicated to management a significant control deficiency. Management immediately corrected the deficiency and the auditor was able to sufficiently test the newly-instituted internal control before the end of the fiscal period.
5. As a result of performing tests of controls, the auditor identified a significant deficiency in internal control over financial reporting; however, the auditor does not believe that it represents a material weakness in internal control.

Required
For each situation, state the appropriate audit report from the following alternatives:
• Unqualified opinion on internal control over financial reporting
• Qualified or disclaimer of opinion on internal control over financial reporting
• Adverse opinion on internal control over financial reporting
