(107)All supervisors involved in group supervision should be able to understand the decisions made, in particular where those decisions are made by the group supervisor. A soon as it becomes available to one of the supervisors, the relevant information should therefore be shared with the other supervisors, in order for all supervisors to be able to establish an opinion based on the same relevant information. In the event that the supervisors concerned cannot reach an agreement, qualified advice from CEIOPS should be sought to resolve the matter.
