Conventional bank licensees are required to submit a quarterly Prudential Information Return (PIR). Conventional bank licensees may apply in writing to CBB for an exemption from the requirement that the PIR be reviewed by the licensee's external auditor: this exemption would normally only be given where the licensee had established a track record of accurate and timely reporting, and there were no other supervisory issues of concern. Further details on the CBB's reporting and related requirements, including the precise scope of the auditor's review and attestation, are contained in Module BR (The CBB Reporting).
