Entity auditors often think in terms of that company’s profit or assets. Group auditors think in terms of the consolidated users — lenders reading the group pack, shareholders of the Hong Kong parent, regulators watching the holding company.
Group versus component
Group materiality is set on consolidated benchmarks: profit before tax, revenue, or total assets, depending on what users care about. Component materiality is lower, so that aggregation risk across entities does not exceed the group threshold.
A small services subsidiary may still be significant if it holds the intercompany treasury function or a related-party guarantee — significance is not only size.
Practical consequences
- Component auditors receive a materiality figure in the group instruction letter
- Trivial thresholds for posting differences are set at group level
- Qualitative matters (fraud risk, compliance) can override quantitative thresholds
If your previous auditor never explained how materiality flowed to Shenzhen or Singapore, ask for the allocation schedule in the planning meeting. It shapes which eliminations get full substantive testing.
