(92)Obliged entities operating in the non-financial sector might also carry out activities across borders or be part of groups that carry out cross-border activities. It is therefore appropriate to lay down rules that define the functioning of AML/CFT supervisory colleges for groups carrying out both financial and non-financial activities, and that enable the setting-up of supervisory colleges in the non-financial sector, taking into account the need to apply additional safeguards in relation to groups or cross-border entities providing legal services. In order to ensure effective cross-border supervision in the non-financial sector, AMLA should provide support to the functioning of such colleges and regularly provide its opinion on the functioning of those colleges as implementation of the enabling framework provided by this Directive progresses.
