Learning Objectives. Illustrate risk model Determine level of OAA Identify risks Calculate detection risk. Session Overview. Purpose of identifying and assessing risk Components Factors influencing risk Risk model How to assess risk. Inherent Risk.
Inherent risk is defined as the risk that in the absence of preventive internal accounting controls, a material error will occur in the accounting process.
The risk of material error occurring in the first place
Control risk is the risk that error that has occurred in the component and that could be material, when aggregated with errors in other components, will not be detected on a timely basis by the internal controls in place.
Detection risk is the risk that the auditor’s procedures will not detect error that exists in the component and that could be material when aggregated with error in other components.
Overall audit risk is the maximum risk that the auditor is prepared to assume that error in the financial statements aggregating to more than materiality will remain undetected at the end of the audit.
OAR = IR x CR x DR
OAR = Overall Audit Risk
IR = Inherent Risk
CR = Internal Control Risk
DR = Detection Risk
SBATHE RELATIONSHIP BETWEEN IR,CR,DR AND AR
OAR = IR x CR x DR
DR = OAR X
CR x IR
OAR = 1- ASSURANCE LEVEL
DST - Detailed Substantive
SBA - Systems Based
(I.e. CR + IR)
Assessment of control risk
2. Assess the component risks starting with inherent risk then control risk;
3. Rearrange model and solve DR
