Islamic bank licensees' Boards of Directors and Shari'a Boards (where applicable) and management must take reasonable care to ensure that their affairs are managed effectively and responsibly, with appropriate systems and controls in relation to the size and complexity of their operations. Islamic bank licensees' systems and controls, as far as is reasonably practical, must be sufficient to manage the level of risk inherent in their business and ensure compliance with the CBB Rulebook. In particular, the CBB requires that banks comply with all AAOIFI issued accounting standards as well as the Shari'a pronouncements issued by the Shari'a Board of AAOIFI.
