Overview

The Audit Risk ModelThe Audit Risk Model

42

The Audit Risk Model Generally Accepted Auditing

Standards establish a “model” for carrying out audits.

43

The Audit Risk Model Requires auditors to use their

judgment . . . In assessing risks, and Then in deciding what procedures

to carry out.

44

Based on . . . The auditor’s assessment of

various risks and any tests of controls, the

auditor makes judgments about kinds of evidence needed to achieve “reasonable assurance.”

45

Some Terms

The Audit Risk ModelThe Audit Risk Model

46

The risk that the auditor may unknowingly fail to appropriately modify his/her opinion on financial statements that are materially misstated.

Audit Risk (AR)

47

The risk that an assertion is susceptible to a material misstatement, assuming there are no related controls.

Inherent Risk (IR)

48

The risk that a material misstatement that could occur in an assertion will not be prevented or detected on a timely basis by the entity’s internal control.

Control Risk (CR)

49

The risk that the auditor will not detect a material misstatement that exists in an assertion.

Detection Risk (DR)

50

AR = IR x CR x DR Highly judgmental The objective in an audit is to

limit audit risk (AR) to a low level, as judged by an auditor.

Mathematially

51

Auditors assess IR and CR along a spectrum

Maximum risk Moderate risk Low risk

Audit Risk

52

A maximum risk assessment (i.e., 100%) means that

the auditor believes controls are unlikely to be effective; or

The evaluation of their effectiveness would be inefficient.
