CAT / FIA FAU Syllabus C. Internal Control - Evaluation of Internal Controls - Notes 3 / 3
Limitations of Internal Controls
Controls are only as good as those applying them..
Collusion from staff
May result in fraud no matter how strong the controls are
Practice is different from theory
The specific circumstances of the entity make some controls unworkable or be manipulated in practice by those involved in the system
If controls are insufficient
More testing needed
Increased sample sizes directly on the specific risk in question
Alternative sources of evidence needed
These could include external confirmation, or analytical procedures
The possibility of FRAUD means substantive testing is always required
