Evidence generated internally is more reliable when the internal control structures are effective. Evidence obtained directly by the auditor is more reliable than evidence obtained from the client. Evidence in the form of documents or written representations is more reliable than oral representations. Evidence provided by original documents is more reliable than evidence provided by photocopies or facsimiles.

17. 5-17 Copyright  2006 McGraw-Hill Australia Pty Ltd Revised PPTs t/a Auditing and Assurance Services in Australia 3e by Grant Gay and Roger Simnett Slides prepared by Roger Simnett Overview of the Audit Risk Model Audit risk is the risk that the auditor will give an inappropriate audit opinion when the financial report is materially misstated. Before issuing an opinion on the financial report, the auditor needs to reduce audit risk to an acceptable level to ensure the opinion is reliable. Learning Objective 6:

18. 5-18 Copyright  2006 McGraw-Hill Australia Pty Ltd Revised PPTs t/a Auditing and Assurance Services in Australia 3e by Grant Gay and Roger Simnett Slides prepared by Roger Simnett Reducing audit risk An auditor reduces audit risk by performing audit procedures until there is sufficient appropriate evidence for each assertion of each significant transaction class or account balance to provide reasonable assurance that the financial reports are not materially misstated. The audit risk model focuses audit effort on those classes of transactions or balances (and the particular assertions) that are likely to contain material misstatements.

19. 5-19 Copyright  2006 McGraw-Hill Australia Pty Ltd Revised PPTs t/a Auditing and Assurance Services in Australia 3e by Grant Gay and Roger Simnett Slides prepared by Roger Simnett Components of audit risk (AR) There are three components: Refer AUS 202/ASA 200 (ISA 200): – Inherent risk (IR):  Susceptibility of an assertion to material misstatement given inherent and environmental characteristics, but without regard to prescribed control procedures. – Control risk (CR):  Risk that material misstatement might not be prevented or detected by internal control procedures. – Detection risk (DR):  Risk that auditors’ substantive procedures lead will auditor to conclude no material misstatement exists when one indeed does.

Auditors cannot directly change control risk. An auditor can obtain evidence to support an assessed level of control risk less than high (expect to rely on internal control) by examining control environment, risk assessment process, information system, control activities and monitoring of controls, and testing their effectiveness.
