Materiality in representations — how is it quantified (e.g., by a USD amount)?
Frequency/market practice: Materiality qualifiers are commonly seen but often not quantified (other than for specific warranties, taking into account the de minimis threshold).
How is knowledge qualified (e.g., specific people, actual/constructive knowledge)?
Frequency/market practice: It is often limited to the actual knowledge and due enquiry of a specified list of senior management and people involved in the deal.
