The CBB uses its own inspectors to undertake on-site examinations of licensees as an integral part of its regular supervisory efforts. In addition, the CBB may commission special investigations of licensees in order to help it assess their compliance with CBB requirements, as contained in Article 121 of the CBB Law. Such investigations may be carried out either by the CBB's own officials, by duly qualified experts appointed for the purpose by the CBB ('Appointed Experts'), or a combination of the two.
