ACCA AA Syllabus B. Planning And Risk Assessment - Difference between Interim and Final audit - Notes 4 / 7
The interim audit is used to lessen the amount of work at the final audit.
Which testing gets done where needs planning - although some tests such as year end stock take can only be performed at the year end as the interim is performed during the year
This is a matter of timing and the auditor has the following choice:
Interim and Final audits
Final audit only
Continually using CAATs
Interim Audits
Basically before the Year-end, allowing procedures to be more spread out and improve planning of the final audit
The interim audit should improve risk assessment and therefore make the final procedures more efficient
It will help with the levels of materiality and allow the final audit to concentrate on year end valuations and matters of significant subjectivity
The interim audit will normally be used for:
Documenting the system
Evaluating controls
Testing specific transactions (e.g. big NCA purchase)
Interim receivables circular
Timings
Early enough - so not interfering with Y/E client work
Late enough - to give adequate warning of specific problems that will need to be addressed
Final Audit
Post year-end, focus on year end valuations and areas of significant subjectivity
