Definition
Control risk (also known as internal control risk) represents the risk that a company’s internal control system will fail to prevent or detect material misstatements in its financial statements. It is a critical element of audit risk, which also includes inherent risk and detection risk. Auditors assess control risk to determine the nature, timing, and extent of substantive testing required during an audit.
Examples
-
Segregation of Duties: An insufficient segregation of duties within the finance department could lead to errors or fraud that the internal control system might not detect. For instance, if the same employee is responsible for both recording transactions and reconciling bank statements, the risk of undetected misstatement increases.
-
Authorization Controls: If the company lacks effective authorization controls, unauthorized transactions might occur without being detected. For example, without proper authorization processes, an employee might make purchases beyond their approval limits.
-
Access Controls: Weak access controls may permit unauthorized personnel to change financial records, leading to potential misstatements that the control system fails to catch.
Frequently Asked Questions
What is the difference between control risk and audit risk?
Audit risk is the risk that the auditor expresses an inappropriate opinion when the financial statements are materially misstated. Control risk is a subset of audit risk and pertains specifically to the likelihood that the internal control system will not catch material misstatements.
How do auditors assess control risk?
Auditors assess control risk by evaluating the design and operational effectiveness of a company’s internal controls. This often involves inquiries, inspections, observations, and tests of control (compliance tests).
What happens if control risk is assessed as high?
If control risk is assessed as high, auditors will need to perform more extensive substantive testing to gain sufficient assurance that the financial statements are free from material misstatement.
Can control risk be reduced?
Control risk itself is inherent to the company’s internal control weaknesses, so it cannot be entirely eliminated. However, implementing and maintaining robust internal controls can reduce the overall risk.
How does control risk influence the audit strategy?
A higher control risk will necessitate a greater emphasis on substantive testing, while a lower control risk allows the auditor to rely more heavily on controls.
