ACCT6007 Chap.3 Business Risk, Audit Risk and Materiality
Business Risk, Audit Risk and Materiality
This chapter translates business conditions into financial-report risks and audit responses. It distinguishes engagement risk, business risk and audit risk, uses the audit-risk relationship to explain allowable detection risk, and develops materiality as a benchmark and qualitative judgement. The central skill is to name the account, direction and assertion between a commercial problem and an audit procedure.
Acceptance and continuance considerations come before detailed planning because integrity, competence, independence and resources determine whether the firm should undertake the engagement. Risk assessment then gathers evidence about the entity, environment, reporting framework and internal control through enquiry, analytics, observation and inspection.
A commercial threat becomes an audit issue only when it can create a material misstatement in a named balance, transaction or disclosure. In the model, inherent and control risk are assessed characteristics of the entity and its controls, while detection risk is influenced through procedure design. Materiality uses a relevant and stable benchmark, a reasoned amount and qualitative context.
Performance materiality is lower than overall materiality to address aggregation risk, and the amount may need revision when actual results differ from the planning basis.

Business Risk, Audit Risk and Materiality FAQ
How does a business threat become an audit risk?
No. Business risk concerns threats to the entity's objectives. It becomes relevant to audit risk when it can create a material misstatement in a named account or disclosure. The answer must show that translation rather than simply repeating the business problem.
Why is detection risk inversely related to assessed risk?
When desired audit risk is fixed, higher inherent or control risk means procedures must have a lower chance of missing misstatement. The auditor responds with more persuasive work through the nature, timing or extent of procedures.
Can materiality be chosen from one fixed percentage?
No. The auditor selects a benchmark relevant to users and considers stability, context and qualitative factors. A smaller amount may still matter if it changes a key trend, hides non-compliance or affects an important decision.
Exam move
Practise risk chains with five headings: condition, account, direction, assertion and response. Recalculate the audit-risk relationship using decimals and state the response in words. For materiality scenarios, explain the benchmark choice before any percentage and add one qualitative factor that could make a smaller amount important.
Compare a stable profit entity, a low-margin retailer and a not-for-profit body so benchmark choice changes with user focus. Do not memorise one percentage as a standard. After every audit-risk calculation, check that higher assessed risk produces lower allowable detection risk and a stronger evidence response.
Rewrite “do more testing” into changes to nature, timing and extent, such as external confirmation, year-end work or larger coverage. Use analytics to propose a risk but do not describe an unusual ratio as a proven misstatement. Add the evidence that would corroborate or refute the explanation.
At completion, revisit the original assessment and materiality basis because contradictory evidence or changed results may require revision. In closed-book practice, label invented numerical inputs clearly and keep them separate from claims about an actual client. Build one counter-case where the benchmark changes because profit becomes unstable, and another where a small amount matters qualitatively.
Explain each change using user decisions rather than a memorised threshold. Finish by stating how each revision changes the planned evidence work. Link every revised benchmark to a specific user decision and assertion.
