3. Relationship between the Internal Audit Unit and the AGSA• The scope of the Internal Audit Unit determined by the

PFMA/MFMA(evaluate effectiveness of internal controls) and the external audit performed by the AGSA are different.

• Irrespective of the degree of autonomy and objectivity of the Internal Audit Unit, such function is not always independent of the entity, as is required of the AGSA.

• The AGSA responsibility is not reduced by the use of the work of this unit.

• The use of Internal audit work impact only the nature, timing and extent of our audit procedures

4. Determining whether to use the work of the internal auditors

• Different audit approach followed by external auditors:– Combined approach (Combination of test of control and substantive test of

details)– Substantive test of details.

• Approach relevant to the use of the internal audit work –combined approach.

• Factors considered when determining the approach:– Results from the System descriptions– Findings highlighted on internal audit reports– The scope of the control testing by the internal auditors– Entity’s risk assessment and risk management strategy– Assessment of the IT controls– Etc.

6. Using specific work of the internal auditors

• To use the specific work of the internal auditors, we evaluate and perform audit procedures on that work to determine adequacy.

• When evaluating the adequacy of the work we consider the following: - Whether the work was supervised, reviewed and documented

- Sufficient, appropriate audit evidence was obtained to enable the internal auditors to draw reasonable conclusion

- Conclusions reached are appropriate in the circumstances and reports prepared are consistent with the results of the work performed

- Any exceptions or unusual matters disclosed by the internal auditors are properly resolved
