(9)Members of the college of supervisors should discuss and agree on the scope and level of involvement of observers, if any, in the college of supervisors. To enhance the cooperation and the exchange of information with the observers, including with the group-level resolution authority and the AML/CFT lead supervisor where relevant, the written coordination and cooperation arrangements should establish the framework for cooperation and information to be exchanged with each of those observers. The written arrangements should also cover agreements between members of the college of supervisors involved in specific activities of the college, including activities carried out through specific substructures of the college of supervisors.
