(54)While establishing a resolution college, it is necessary to avoid duplication of work already conducted by the consolidating supervisor and the supervisory college. It is also important to ensure that this work will be adjusted to respond to the needs of the functioning of the college. In particular, it is appropriate to ensure that the group-level resolution authority takes into account, updates and adjusts accordingly all relevant work conducted by the consolidating supervisor in the context of the supervisory college, in particular with regard to the identification of relevant group entities and consequently the authorities which should be invited to become members or observes of the college (‘mapping process’).
