Objective
To prepare audit documentation that provides a sufficient and appropriate record of the basis for the auditor's report, and evidence that the audit was planned and performed in accordance with the SAs.
Key requirements
- Sufficient detail for an experienced auditor with no previous connection to understand the work
- Documentation of: nature, timing, extent of procedures; results obtained; significant matters; conclusions
- Identification of preparer and reviewer of each significant working paper
- Final audit file assembled within 60 days of the auditor's report date
- Retention for at least 7 years (SQM 1)
Typical procedures
- Lead schedule per FS line item
- Working paper for each SA-driven procedure
- EQR documentation where applicable
- Cross-references between working papers
Common pitfalls
- Conclusions stated without supporting evidence cited
- Late changes to the file after sign-off without proper "subsequent event" documentation
- Working papers prepared but never reviewed — no reviewer initials
