2. ASA 200 deals with the overall objectives of the auditor in conducting an audit of the financial report,[1] including to obtain sufficient appropriate audit evidence to reduce audit risk to an acceptably low level.[2] Audit risk is a function of the risks of material misstatement and detection risk.[3] ASA 200 explains that the risks of material misstatement may exist at two levels:[4] the overall financial report level; and the assertion level for classes of transactions, account balances and disclosures.

3. ASA 200 requires the auditor to exercise professional judgement in planning and performing an audit, and to plan and perform an audit with professional scepticism recognising that circumstances may exist that cause the financial report to be materially misstated.[5]

4. Risks at the financial report level relate pervasively to the financial report as a whole and potentially affect many assertions. Risks of material misstatement at the assertion level consist of two components, inherent and control risk:

• Inherent risk is described as the susceptibility of an assertion about a class of transaction, account balance or disclosure to a misstatement that could be material, either individually or when aggregated with other misstatements, before consideration of any related controls.
• Control risk is described as the risk that a misstatement that could occur in an assertion about a class of transaction, account balance or disclosure and that could be material, either individually or when aggregated with other misstatements, will not be prevented, or detected and corrected, on a timely basis by the entity’s system of internal control.

5. ASA 200 explains that risks of material misstatement are assessed at the assertion level in order to determine the nature, timing and extent of further audit procedures necessary to obtain sufficient appropriate audit evidence.[6] For the identified risks of material misstatement at the assertion level, a separate assessment of inherent risk and control risk is required by this ASA. As explained in ASA 200, inherent risk is higher for some assertions and related classes of transactions, account balances and disclosures than for others. The degree to which inherent risk varies is referred to in this ASA as the ‘spectrum of inherent risk.’

6. Risks of material misstatement identified and assessed by the auditor include both those due to error and those due to fraud. Although both are addressed by this ASA, the significance of fraud is such that further requirements and guidance are included in ASA 240 in relation to risk assessment procedures and related activities to obtain information that is used to identify, assess and respond to the risks of material misstatement due to fraud.
