Risks (Audit Risk Formula)

Component of Audit Risk Inherent risk Errors likely to occur In client s financial statements Control risk Detection risk Audit risk Errors not detected by controls Errors that bypass controls Errors caught by auditor Errors undetected by auditor Page 2

Different Types of Risk Inherent Risk The susceptibility of an account balance, disclosure or class of transactions, considered at the assertion level, to a material misstatement, assuming there are no related controls. Control Risk The risk that a material misstatement that could occur in an account balance, disclosure or class of transactions, considered at the assertion level, will not be prevented or detected and corrected on a timely basis by the client s internal control system. Detection Risk The risk that the auditors will not detect a material misstatement that exists in an account balance, disclosure, or class of transactions assertion considered at the assertion level. Audit Risk The risk that the auditors may unknowingly fail to modify our opinion appropriately on financial statements that are materially misstated Page 3

Types of risks: Inherent Risk Inherent risk It implies that auditors should attempt to predict where misstatements are most and least likely in the FS segments (account or class of transactions). Inherent risks is a measure of the likelihood that there are material misstatements (errors or fraud) in a segment (class of transactions / account balance) before considering the effectiveness of internal controls Þ Þ Þ At the start of the audit, there is nothing that can be done about changing the inherent risk. The auditor must assess the factors that make up the inherent risk and take them into consideration when obtaining audit evidence. Auditors begin their assessment of inherent risk during the planning phase and update the assessment as the audit progresses. Page 4

Types of risks: Control Risk Control risk The assessment of the likelihood that a misstatement that could occur and that could be material will not be prevented or detected the internal control system. Ideally, the control system would detect any material errors before they enter the financial statements. Page 5

Types of risks: Detection Risk Detection risk Is a measure of the risk that audit evidence (substantive procedures planned by the auditor to detect material misstatements in the FS: tests of details of transactions, tests of details of balances, and analytical procedures) will fail to detect misstatements that could be material è The Detection risk depends on other factors and is inversely related to the accumulation of inherent and control risk Combined Risk Assessment è It determines the number of substantial elements of proof the auditor plans to accumulate in order to reduce the Detection risk to an acceptable level. Page 6

Audit Formula The audit risk The audit risk is the ultimate acceptable risk that material monetary errors are not detected. AUDIT RISK FORMULA Inherent Risk X Control Risk X Detection Risk = Audit Risk Combined Risk Assessment Page 7
