3. The ECB shall establish and maintain comprehensive and formal procedures including ethics procedures and proportionate periods to assess in advance and prevent possible conflicts of interest resulting from subsequent employment within two years of members of the Supervisory Board and ECB staff members engaged in supervisory activities, and shall provide for appropriate disclosures subject to applicable data protection rules.
Those procedures shall be without prejudice to the application of stricter national rules. For members of the Supervisory Board who are representatives of national competent authorities, those procedures shall be established and implemented in cooperation with national competent authorities, without prejudice to applicable national law.
For the ECB staff members engaged in supervisory activities, those procedures shall determine categories of positions to which such assessment applies, as well as periods that are proportionate to the functions of those staff members in the supervisory activities during their employment at the ECB.
