6. If the ECB (a) decides to assume the direct supervision of a supervised entity or supervised group or (b) decides that the direct supervision of a supervised entity or supervised group by the ECB shall end, the ECB and the relevant NCA shall cooperate in order to ensure the smooth transition of supervisory competences. In particular, a report setting out the supervisory history and risk profile of the supervised entity shall be prepared by the relevant NCA when the ECB assumes the direct supervision of a supervised entity, and by the ECB when the relevant NCA becomes competent to supervise the entity concerned.
