Can firms choose whether to contextualise by group or by legal entity?
If firms report their data by legal entity, they must publish it by legal entity. If they provide a joint report (under DISP 1.10.1C), the data must be published on the same basis. Contextualisation would normally relate to the published tables for each firm or group of firms, but where contextualisation data can only be provided on a group basis, firms may aggregate their data to match this (as long as the required data tables are also published). The onus is on the firm to ensure its contextualisation metrics are informative and not misleading.
