What is Unmodified opinion?
Also known as: clean opinion
The opinion the auditor expresses on concluding that the financial statements are prepared, in all material respects, in accordance with the applicable financial reporting framework. This does not mean "there is not a single error in the statements": the auditor has only obtained reasonable assurance that there is no material misstatement. Even if an "Emphasis of matter" paragraph is added to the report, the opinion remains unmodified, because that paragraph does not change the opinion but only draws the reader's attention to a particular note in the statements. If a material misstatement is found or sufficient evidence cannot be obtained, the auditor moves to a modified opinion.
