Materiality in representations — how is it quantified (e.g., by a USD amount)?
Frequency/market practice: Fairly common; materiality qualifiers are commonly seen, but are often not quantified (other than specific warranties, e.g., contract value).
How is knowledge qualified (e.g., specific people, actual/constructive knowledge)?
Analysis: Knowledge qualifiers are common, often limited to the actual knowledge and due enquiry of a specified list of senior management.
