Audit Opinion
The auditor's formal conclusion on the adequacy of the control system examined.
The audit opinion is the conclusion issued by the audit team at the end of an engagement. For internal audit, opinions include: satisfactory, partially satisfactory, unsatisfactory (terminology varies). For external audit (per ISA/PCAOB), opinions include: unqualified (clean), qualified, adverse, or disclaimer of opinion. The opinion is the key deliverable of an audit report and engages the professional responsibility of the auditor. It must be supported by sufficient and appropriate evidence.
📌 Key points
- The opinion engages the auditor's professional responsibility — it cannot be arbitrary
- Internal: satisfactory / partially satisfactory / unsatisfactory
- External: unqualified / qualified / adverse / disclaimer of opinion
- An adverse opinion or disclaimer has severe regulatory and financial consequences
- The opinion must be consistent with findings — documented evidence is essential
