At the time of authorisation (when the license is granted) or whenever a change occurs, in order to maintain an up-to-date record of authorised signatories of respective ancillary service providers, the CBB requires all licensees to submit to the licensee's CBB supervisory point of contact a list of specimen signatures of the officials authorised to sign on behalf of the concerned licensee, together with, where appropriate, details of what they are authorised to sign for.
