Note the mentionof materiality inthe audit report.

Materiality is the magnitude of omittedor misstated information that probably
would have made a difference in thejudgment of someone relying on that
information (FASB 2).
What ismateriality?
6
For each engagement, auditors For each engagement, auditors typically establish a typically establish a preliminary preliminary
judgment about materialityjudgment about materiality..
The preliminary judgmentabout materiality is the maximumamount by which the auditor be-lieves the statements could be
misstated and still not affect thedecisions of reasonable users.
7
For each engagement, auditors For each engagement, auditors typically establish a typically establish a preliminary preliminary
judgment about materialityjudgment about materiality..- may be based on a firm-wide formula considering profitability and/or total assets, e.g., 6% of net income
adjusted accordingto auditor judgment

- materiality is strongly influenced by client size- multiple bases of materiality may be appropriateFOR EXAMPLE: The auditor may be concerned that:net income is not misstated by $100,000,and total assets is not misstated by$300,000.

What is acceptable audit risk?
Acceptable audit risk is therisk that the auditor is willingto accept that an unqualified
opinion will be issued for statements that are materially
misstated.

Inherent RiskInherent Risk- defined as the risk that material mis- statements exist before considering the client internal controls- some accounts, components, cycles are inherently riskier than others
auditors must:- identify inherently risky areas- gather appropriate evidence regarding those areas
