Question
You are planning an internal audit of the procurement function. To set a materiality threshold for monetary misstatements and control deficiencies, which approach is most appropriate?
Show the answer and explanation
Correct answer: B. Select a quantitative benchmark (such as a percentage of a relevant financial base) and reduce it when qualitative factors (fraud risk, regulatory sensitivity, stakeholder concern) increase significance
The best practice is to use a quantitative benchmark and then reduce the threshold for qualitative factors that increase the importance of smaller misstatements. This balances objective measurement with professional judgment when fraud risk, regulatory consequences, or stakeholder expectations make smaller errors significant. Option 0 is wrong because a fixed percentage without adjustment ignores context and qualitative risks. Option 2 is wrong because automatic zero-tolerance is impractical and ignores materiality’s monetary concept; not all noncompliance is material. Option 3 is wrong because materiality is set during planning, not derived solely from preliminary estimates of misstatements, which are often incomplete.
