Licensees must promptly notify the CBB in writing when a person undertaking a controlled function will no longer be carrying out that function together with an explanation as to the reasons for not undertaking the controlled function. In such cases, their approved person status is automatically withdrawn by the CBB. If a controlled function falls vacant, the 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 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.
