(AU-C Section 230.05)
REQUIREMENTS
Requirement for Audit Documentation

About the conclusions reached; and
That the audit was planned and performed in accordance with GAAS and relevant legal and regulatory requirements.

Audit documentation also:

Provides documentation for internal review and inspections and external reviews
Provides documentation for successor auditors
Helps auditors understand prior year words
Form, Content, and Extent of Audit Documentation
The quantity, type, and content of the audit documentation are based on the auditor’s professional judgment and vary with the engagement. Factors to consider in determining the content of audit documentation are discussed in the following paragraphs.
The Audience
The auditor should prepare audit documentation on a timely basis that would allow an experienced auditor1 having no previous connection with the audit to understand:
The nature, timing, and extent of auditing procedures performed to comply with GAAS and applicable legal and regulatory requirements;
The results of the audit procedures performed and the audit evidence obtained; and
The significant findings for issues that arose during the audit, the conclusions reached on those significant matters, and professional judgments made in reaching those conclusions.
