Directors must disclose their concern or interest in companies, bodies corporate, firms or associations (including shareholding interests) by written notice in Form MBP 1; the director must cause the interest to be disclosed at the board meeting immediately following the notice. All such notices are to be kept at the registered office for the prescribed retention period and held in the custody of the company secretary or an authorized person.
