Frequency/market practice: Fairly common; materiality qualifiers are commonly seen but often not quantified (other than specific warranties, e.g., contract value).
Frequency/market practice: Knowledge qualification is rare for private deals. It is common for private equity deals, including add-ons (both with respect to a specific group of people and having regard to constructive knowledge and due enquiry). Where a warranty and indemnity policy is entered into in connection with an acquisition a knowledge qualifier is less likely to be included (as warranty and indemnity policies usually require a low level of knowledge qualifiers in order to obtain satisfactory coverage).
