Audit risk is the risk that the auditor expresses an inappropriate audit opinion when the financial statements are materially misstated. In simple terms, audit risk is the risk that an auditor will issue an unqualified opinion when the financial statements contain material misstatement.
ISA 200 states that auditor should plan and perform the audit to reduce audit risk to an acceptably low level that is consistent with the objective of an audit. (Auditing and Assurance Standard) AAS-6(Revised), “Risk Assessments and Internal Controls”, identifies the three components of audit risk i.e. inherent risk, control risk and detection risk.
Audit Risk Model: AR = IR x CR x DR
Where,
- AR= Audit risk (the risk that the auditor may unknowingly fail to appropriately modify his or her opinion on financial statements that are materially misstated)
- IR = Inherent risk (the risk that an assertion is susceptible to a material misstatement, assuming there are no related controls) : Inherent Risk is the auditor’s measure of assessing whether material misstatements exist in the financial statement before considering of internal controls.
