(15)Each college of supervisors should decide on the information to be exchanged and periodically updated and should list that information in the written coordination and cooperation arrangements. To enhance the capacity of the college of supervisors to identify increasing risks and vulnerabilities, members of the college of supervisors and, where relevant, observers should regularly exchange quantitative and qualitative information. Furthermore, the written coordination and cooperation arrangements should provide for the procedure for coordinating the relevant input, and the responsibilities and role of the consolidating supervisor in communicating that input to observers. To ensure that the exchange of information is triggered between the consolidating supervisors and the members of the college of supervisors where the group or its entities are impacted by an event of adverse material effect, the consolidating supervisor and the members of the college of supervisors should specify the main characteristics of such event in the written coordination and cooperation arrangements, taking into account the specificities of the group, and should agree on the information to be exchanged, where such event of adverse material effect arises.
