Unmodified Auditor's Report
Issued when the auditor concludes they have obtained reasonable assurance that the financial report is free from material misstatement.
Requires that sufficient appropriate audit evidence has been obtained according to \text{ASA 330/ISA 330}, any uncorrected misstatements are immaterial per \text{ASA 450/ISA 450}, and that the financial report follows the applicable financial reporting framework based on \text{ASA 700/ISA 700}.
Modifications Affecting the Auditor’s Opinion
Modifications must be material to the financial report.
Serious modifications (adverse opinions and disclaimers) must be pervasive.
Pervasive Effects:
Not confined to specific elements.
If confined, represent a substantial portion of the financial report.
Fundamental to users' understanding regarding disclosures (\text{ASA 705.5/ISA 705.5}$).
Qualified Opinion
Expressed when misstatements are material but not pervasive, or when the auditor cannot obtain sufficient evidence but believes the possible effects could be material but not pervasive (\text{ASA 705.07/ISA 705.07}
Indicates that circumstances exist which are material, but not so material/pervasive as to affect the entire financial report.
Adverse Opinion
Expressed when misstatements are so material and pervasive that the financial report is misleading (\text{ASA 705.08/ISA 705.08}
Indicates the subject matter is misleading.
Disclaimer of Opinion
Expressed when the auditor cannot obtain sufficient evidence and concludes that undetected misstatements could be both material and pervasive (\text{ASA 705.09/ISA 705.09}$$
Indicates the auditor is unable to express an opinion.
Occurs if a scope limitation exists.
Additional Communications - Emphasis of Matter and Other Matter
ASA 706 (ISA 706) covers situations where the auditor draws attention to matters fundamental to users' understanding (Emphasis of Matter) or other relevant matters (Other Matter).
Emphasis of Matter is used when a matter is appropriately presented but needs emphasis.
Examples include:
Uncertainty relating to litigation
Early application of accounting standards
Major catastrophes
Material Uncertainty Related to Going Concern
If the going concern basis is appropriate but a material uncertainty exists with adequate disclosure, the auditor expresses an unmodified opinion and includes a separate paragraph.
If disclosure is inadequate, the auditor issues a qualified or adverse opinion.
Other Matter Paragraph (ASA 706.7(b)/ISA 706.7(b))
Used to highlight matters not presented in the financial report.
Examples include:
Inability to withdraw from an audit due to scope limitations.
Elaboration on auditor responsibilities required by national regulations.
Financial reports prepared under multiple frameworks.
