Understand the four types of audit opinions for the CPA AUD exam. Learn when unmodified, qualified, adverse, and disclaimer opinions are appropriate.
Audit Report Types: Complete Guide for CPA Candidates
The auditor's report is the culmination of the entire audit process. Understanding the different types of audit opinions and when each is appropriate is one of the most critical topics on the AUD exam. AU-C Section 700 (Forming an Opinion and Reporting on Financial Statements), AU-C 705 (Modifications to the Opinion), and AU-C 706 (Emphasis-of-Matter and Other-Matter Paragraphs) provide the authoritative guidance.
The Unmodified (Unqualified) Opinion
An unmodified opinion is issued when the auditor concludes that the financial statements are presented fairly, in all material respects, in accordance with the applicable financial reporting framework. This is the standard, or clean, audit report. The standard unmodified report for a nonpublic entity under AICPA standards includes a title that includes the word "independent," an addressee, an introductory paragraph identifying the financial statements audited, a section describing management's responsibility for the financial statements, a section describing the auditor's responsibility, an opinion paragraph, and the auditor's signature and date.
For public companies under PCAOB standards, the report format differs and includes additional elements such as the critical audit matters (CAMs), which are matters communicated to the audit committee that relate to accounts or disclosures that are material and involved especially challenging, subjective, or complex auditor judgment.
The Qualified Opinion
A qualified opinion is issued when the auditor concludes that misstatements are material but not pervasive to the financial statements, or when the auditor is unable to obtain sufficient appropriate audit evidence but concludes that the possible effects of undetected misstatements could be material but not pervasive. The qualified opinion states that except for the effects of the matter described, the financial statements are presented fairly. The report includes a Basis for Qualified Opinion paragraph that describes the matter giving rise to the qualification, placed immediately before the opinion paragraph.
A qualification due to a material misstatement occurs when management has not applied GAAP correctly (for example, failing to record a material contingent liability) and the effect is material but not pervasive. A qualification due to a scope limitation occurs when the auditor cannot obtain sufficient evidence about a specific assertion, and the possible effects are material but not pervasive (for example, the auditor cannot observe inventory because of timing but inventory is not the predominant asset).
The Adverse Opinion
An adverse opinion is issued when the auditor concludes that misstatements are both material and pervasive to the financial statements. This means the financial statements as a whole do not present fairly the financial position, results of operations, or cash flows in accordance with the applicable framework. The adverse opinion is the most serious modification. The report includes a Basis for Adverse Opinion paragraph describing the matter and its effects. An adverse opinion is required when a departure from GAAP is so significant that the financial statements taken as a whole are misleading.
The Disclaimer of Opinion
A disclaimer of opinion is issued when the auditor is unable to obtain sufficient appropriate audit evidence on which to base an opinion, and the auditor concludes that the possible effects of undetected misstatements could be both material and pervasive. In a disclaimer, the auditor states that the auditor does not express an opinion on the financial statements. The auditor's responsibility section is modified to state that the auditor was engaged to audit (rather than "has audited"), and it does not include statements about GAAS being followed or evidence being sufficient. A disclaimer may be appropriate when there is a severe scope limitation imposed by management or when there are multiple uncertainties with potential cumulative effects.
Decision Framework for Report Modifications
The decision about which opinion to issue depends on two factors: the nature of the matter giving rise to the modification (misstatement vs. inability to obtain evidence) and the auditor's judgment about the pervasiveness of the effects. When misstatements are detected and they are material but not pervasive, issue a qualified opinion. When misstatements are material and pervasive, issue an adverse opinion. When there is an inability to obtain sufficient evidence and the possible effects are material but not pervasive, issue a qualified opinion. When the inability to obtain evidence means possible effects are material and pervasive, issue a disclaimer.
Key Report Elements and Formatting
Several formatting rules apply to modified reports. The Basis for Opinion paragraph (whether Basis for Qualified Opinion, Basis for Adverse Opinion, or Basis for Disclaimer of Opinion) is always placed immediately before the Opinion paragraph. When issuing a qualified or adverse opinion due to a misstatement, the auditor must describe and quantify the financial effects in the Basis for Opinion paragraph, if practicable. When it is not practicable to determine the effects, the auditor states so in the paragraph.
Comparative Financial Statements
When reporting on comparative financial statements, the auditor may issue different opinions on each period. For example, the auditor might issue an unmodified opinion on the current year and a qualified opinion on the prior year if the prior year contained a known departure from GAAP. If a prior year opinion has changed (for example, from qualified to unmodified because the matter was resolved), the auditor should include an Other-Matter paragraph explaining the change.
Exam Tips for Audit Report Types
- Material but not pervasive leads to a qualified opinion; material and pervasive leads to adverse (misstatement) or disclaimer (scope limitation).
- A scope limitation imposed by management is more likely to result in a disclaimer than one caused by circumstances.
- The Basis for Opinion paragraph always precedes the Opinion paragraph.
- An adverse opinion is about detected misstatements; a disclaimer is about the inability to obtain evidence.
- Know the differences between AICPA and PCAOB report formats, including CAMs for PCAOB reports.
