Islamic bank licensees are encouraged to notify the BMA as soon as they become aware of events that are likely to lead to changes in their controllers. The criteria by which the BMA assesses the suitability of controllers are set out in Section GR-5.3. The BMA aims to respond to requests for approval within 30 calendar days. The BMA may contact references and supervisory bodies in connection with any information provided to support an application for controller. The BMA may also ask for further information, in addition to that provided in Form 2, if required to satisfy itself as to the suitability of the applicant.
