Audit Opinion
The independent auditor's conclusion on whether the financial statements are fairly presented. An unqualified (clean) opinion means the auditor found no material problem it needed to flag.
How to calculate it
Unqualified opinion: the statements present fairly, in all material respects, the company's financial position and resultsUnqualified with a going concern paragraph: the auditor has substantial doubt that the company can continue operating for a yearAdverse opinion: the statements are not fairly presentedDisclaimer of opinion: the auditor could not obtain enough evidence to form an opinionInternal control over financial reporting (SOX Section 404): a separate opinion for larger companies; an adverse ICFR opinion means a material weakness existsHow to read it
- Nearly every U.S. listed company gets an unqualified opinion, and the SEC generally does not accept qualified or adverse opinions in filings. What to read is the extra content: a going concern paragraph, critical audit matters and any material weakness in internal control.
- A going concern paragraph is the most important warning in an audit report. It means the auditor doubts the company can keep operating for the next 12 months without new financing or restructuring.
- Critical audit matters (CAMs) list the areas the auditor found most challenging or subjective, such as goodwill impairment, revenue recognition or reserves. They show where the judgment calls in the numbers are.
Common pitfalls
- A clean opinion is not a guarantee against fraud. Audits rely on sampling, and many companies that later restated had clean opinions for years.
- An auditor resigning or being dismissed is a signal on its own, especially just before the 10-K is due. It is disclosed on Form 8-K Item 4.01.
- Smaller companies (non-accelerated filers) are exempt from the auditor's internal control attestation, so they may have control problems that no auditor has tested.
- Form 8-K Item 4.02, non-reliance on previously issued financial statements, means past numbers are wrong and will be restated, which is more serious than most audit report wording.
Where to find it in a 10-K
The auditor's report sits just before the financial statements in Item 8 of the 10-K, together with any separate report on internal control. Management's assessment of internal control is in Item 9A. Auditor changes and non-reliance notices appear on Form 8-K (Items 4.01 and 4.02).
U.S. vs. China reporting
In China a qualified opinion is relatively common, and a disclaimer or adverse opinion on the annual report triggers *ST delisting risk warning under exchange rules. In the U.S., qualified opinions are essentially absent from filings, so the meaningful signals are going concern paragraphs, material weaknesses, auditor changes and restatements.
