## Final Assembly of the Audit File (SA 230)
### The 60-Day Rule
The auditor must complete the administrative process of assembling the final audit file within 60 days of the date of the auditor's report.
### Nature of the Assembly Process
Final assembly is an administrative process only. It must NOT involve:
- Performing new audit procedures
- Drawing new audit conclusions
### Permissible Changes During Final Assembly
Changes are allowed only if they are administrative in nature:
| Permissible | Not Permissible |
|---|---|
| Deleting/discarding superseded documentation | Performing new audit procedures |
| Sorting, collating, cross-referencing working papers | Drawing new audit conclusions |
| Signing off on completion checklists | Adding new substantive audit evidence dated after report |
| Documenting evidence agreed before report date | Changing existing audit conclusions |
### After Final Assembly: Retention Rule
Once the final audit file is assembled, the auditor shall not delete or discard any audit documentation before the end of the retention period. Even documents that appear redundant cannot be removed.
### Practical Timeline
```
