Final answer:
The auditor does not present omitted information in the audit report but should issue a qualified or an adverse opinion if the omission significantly distorts the fair presentation of the financial statements. The qualification can also be communicated in an emphasis of matter or other matter paragraph preceding the opinion in the auditor's report.
Step-by-step explanation:
When a client fails to include information necessary for the fair presentation of financial statements, the responsibility does not fall on the auditor to present this information in the audit report. Instead, the auditor should address the omission according to auditing standards. If the omitted information significantly impacts the financial statements such that they no longer present a fair view, the auditor should issue either a qualified or an adverse opinion.
Typically, the auditor communicates the nature of the omission and its effect on the financial statements. If the matter is sufficiently material and pervasive, it may lead to an adverse opinion, indicating that the financial statements do not present a true and fair view. If the issue is material but not pervasive, a qualified opinion may be given, stating that except for the effects of the matter to which the qualification relates, the financial statements present a true and fair view. In some standards, the auditor may include the qualification in an emphasis of matter paragraph or other matter paragraph that precedes the opinion paragraph in the auditor's report, to draw attention to the user regarding the omission.
