Audit Risk
Audit Risk is the risk that the auditor may unknowingly fail to appropriately modify his or her opinion on financial statements that are materially misstated.
Audit Risk is also defined as a function of the risk that the financial statements
prepared by management are materially misstated and the risk that the auditor will not detect such material misstatement
Responsibility to Detect Fraud or Errors
AU-C 240.05 An auditor conducting an audit in
accordance with GAAS is responsible for obtaining reasonable assurance that the financial statements as a whole are free from material misstatement, whether caused by fraud or error.
Note that the responsibility extends to both errors
and fraud. While it is true that an auditor is not an insurer and an audit does not constitute a guarantee, the auditor should exercise due care in planning, performing, and evaluating of the results of audit procedures, and the proper degree of professional skepticism to achieve such reasonable assurance
This responsibility remains despite concealment through employee collusion or management override of the internal control structure (although detection under such conditions is much more difficult and less likely).
The auditor should always be alert to the possible existence of material error or fraud.
Audit Risk
determine a materiality level for the financial statements as a whole for the purpose of:
Risk
Risk may be assessed in:
quantitative (percentages)
or
non-quantitative terms (high, medium, low).
Audit Risk
Control Risk, Detection Risk and Inherent Risk may each be assessed in non-quantitative terms.
These risks are the components of Audit Risk that may be assessed in both quantitative terms such as percentages or in non-quantitative terms that rely on the experience, observation, and judgment of the auditor.
Audit Risk Model
Audit Risk Model
AR= IR * CR * DR
As inherent risk and control risk increases detection risk will decrease
A high risk of material misstatement requires lower Detection Risk so that overall Audit Risk is acceptable
Inherent Risk
Inherent Risk is the susceptibility of a financial statement assertion to a misstatement that could be material, either individually or when aggregated with other misstatements, assuming that there are no related controls.
Inherent Risk is not directly related to Control or Detection Risk and is uncontrolled by the auditor.
Control Risk
Control Risk is the risk that a misstatement that could occur in a relevant assertion and that could be material, either individually or when aggregated with other misstatements, will not be prevented or detected on a timely basis by the entity’s internal control.
A lack of segregation of duties would present a Control Risk, as would poor physical access controls to blank check stock.
Inherent Risk and Control Risk
Inherent Risk and Control Risk are the entity’s risks, that is, they exist independently of the audit of the financial statements.
The Standards describe the risk of material misstatement as the auditor’s combined assessment of Inherent Risk and Control Risk
The auditor may make separate assessments of Inherent Risk and Control Risk.
Detection Risk
Detection Risk is the risk that the auditor will not detect a misstatement that exists in a relevant assertion that could be material, either individually or when aggregated with other misstatements.
Detection Risk is a function of the effectiveness of an audit procedure and its application by the auditor.
Detection Risk
Only Detection Risk (unlike Inherent Risk and
Control Risk) can be changed at the discretion of the auditor to compensate for the assessed levels of the other two.
If the assessed level of Control Risk is increased, the auditor must decrease the acceptable level of Detection Risk.
This means the auditor would have to perform more substantive testing to offset the decreased reliability of internal control.
Detection Risk
Detection Risk relates to the substantive audit procedures and is managed by the auditor’s response to risk of material misstatement.
The risk of material misstatement and Detection Risk are inversely related;
The greater the risk of material misstatement, the less the Detection Risk that can be accepted by the auditor.
The higher the risk of material misstatement, the lower the Detection Risk must be, and the more
substantive procedures the auditor must perform in order to lower the overall Audit Risk
Misstatements
Misstatements may be of two types:
Known and Likely
Fraud
When the auditor encounters evidence of potential fraud, regardless of its materiality, the auditor should consider the implications for the integrity of management or employees and the possible effect on other aspects of the audit.
When fraud is detected, the auditor should be concerned about the integrity of management or employees and the possible effect on the other aspects of the audit.
Materiality limits do not apply when obtaining written client representations regarding instances of fraud involving management.
Detection Risk
Detection Risk is the risk that the auditors fail to detect a material misstatement in the financial statements.
Misapplication or omission of critical audit procedures may result in a material misstatement remaining undetected by the auditor.
Some detection risk is always present due to the inherent limitations of the audit such as the use of sampling for the selection of transactions.
Detection risk can be reduced by auditors by increasing the number of sampled transactions for detailed testing.
Risk Discussion with Audit Team
Responsibilty for Fraud
The primary responsibility for the prevention and detection of fraud is given primarily to those charged with governance and management.
Management, with the oversight of those charged with governance, must place an emphasis on fraud prevention.
The internal auditor’s responsibility comes into play for the detection of fraud, not its prevention.
