A risk-based audit refers to the form of audit where emphasis is put on areas where there are highest chances of material misstatement, fraud, or operational failure. The auditor considers inherent risk, control effectiveness and materiality rather than put equal effort in testing each account to decide where to concentrate on procedures.
Key Principles
Risk Identification: The high-risk areas should be identified based on the knowledge of the business, industry, internal controls, and previous audit results.
Risk Assessment: Determine the risks as high, medium, or low depending on the probability and the possible financial impact.
Audit Response: Issue audit resources and design procedures in accordance with the levels of risk.
Continuous Review: Change the risk assessment with the emerging information in the audit.
Why It’s Important
Enhances efficiency in audit through the elimination of redundant testing.
Increases quality of audit by emphasizing areas of actual financial reporting exposure.
Assists with audit standards (i.e. ISA 315 and ISA 330).
Integrates audit activity with organizational governance and risk management.
Example
In case the valuation of inventory is very subjective and error-prone in the past, it undergoes a closer testing than stable and low risk accounts, such as prepaid insurance.
To sum up: Risk-based audit aligns audit processes in accordance with the extent of the risk to guarantee that resources are utilized efficiently to produce a more superior, relevant audit judgment.
