(c) Explain the possible impact of RBG outsourcing its internal audit services on the audit of the financialstatements by Grey Co. (4 marks)

正确答案：
(c) Impact on the audit of the financial statements
Tutorial note: The answer to this part should reflect that it is not the external auditor who is providing the internal audit
services. Thus comments regarding objectivity impairment are not relevant.
■ As Grey & Co is likely to be placing some reliance on RBG’s internal audit department in accordance with ISA 610
Considering the Work of Internal Auditing the degree of reliance should be reassessed.
■ The appointment will include an evaluation of organisational risk. The results of this will provide Grey with evidence,
for example:
– supporting the appropriateness of the going concern assumption;
– of indicators of obsolescence of goods or impairment of other assets.
■ As the quality of internal audit services should be higher than previously, providing a stronger control environment, the
extent to which Grey may rely on internal audit work could be increased. This would increase the efficiency of the
external audit of the financial statements as the need for substantive procedures should be reduced.
■ However, if internal audit services are performed on a part-time basis (e.g. fitting into the provider’s less busy months)
Grey must evaluate the impact of this on the prevention, detection and control of fraud and error.
■ The internal auditors will provide a body of expertise within RBG with whom Grey can consult on contentious matters.
Tutorial note: Appropriate credit will be given for arguing that less reliance may be placed on internal audit in this year of
change of provider.
