I recommend having an EDD review checklist with different sections for transactional activity (cash in, cash out, wires in, wires out, monetary instruments, RDC, ACH, checks, etc.) The checklist should have a narrative summary describing why the customer's activity is expected, not suspicious, and whether the customer's BSA risk should be changed based on the transactional activity reviewed during the quarter.
I think you should keep the supporting transactional activity documentation in an electronic file for each high-risk customer that can be accessed as needed for regulators, auditors, management, or Board.
