There is regulatory guidance that addresses this question. In the Interagency Policy Statement on Coordination and Communication Between External Auditors and Examiners
, it states:
"Consistent with prior practice, a depository institution should provide its external auditors with a copy of certain reports and supervisory documents, including:
- The most recent regulatory Report of Condition (i.e., "Call Reports" for banks, and "Thrift Financial Reports" for savings institutions);
- The most recent examination report and pertinent correspondence received from its regulator(s);
- Any supervisory memorandum of understanding with the institution that has been put into effect since the beginning of the period covered by the audit;
- Any written agreement between a federal or state banking agency and the institution that has been put into effect since the beginning of the period covered by the audit; and
- A report of: Any actions initiated or undertaken by a federal banking agency since the beginning of the period covered by the audit under certain subsections of Section 8 of the Federal Deposit Insurance Act2, or any similar action taken by an appropriate state bank supervisor under state law; and Any civil money penalty assessed under any other provision of law with respect to the depository institution or any institution-affiliated party, since the beginning of the period covered by the audit."
