In accordance with Paragraph AU-5.2.8, investment firm licensees must promptly notify the CBB in writing as soon as they become aware, when a person undertaking a controlled function will no longer be carrying out that function. If a controlled function falls vacant, the investment firm licensee must appoint a permanent replacement (after obtaining CBB approval), within 120 calendar days of the vacancy occurring. Pending the appointment of a permanent replacement, the investment firm licensee must make immediate interim arrangements to ensure continuity of the duties and responsibilities of the controlled function affected, provided that such arrangements do not pose a conflict of duties. These interim arrangements must be approved by the CBB.
