Abstract: Various methods for allowing a due diligence service provider to assist a financial institution with a regulatory or statutory compliance requirement are disclosed. The method may include receiving data from at least one recordkeeping system operatively associated with client accounts of the financial institution, wherein the account data include at least one account of a foreign financial institution; reviewing the account data to identify at least one foreign correspondent account which triggers at least one regulatory or statutory compliance requirement; eliminating account records not associated with a foreign financial institution; and, validating at least part of the account data by communicating a supplemental application to a client of the financial institution to determine applicability of the compliance requirement to the account data.
