Robert Mazur briefly reviews the key issues previously covered in Part 3 of this series that addressed what a money launderer looks like. He then discusses one of four primary factors one should assess to determine money laundering risk, the “BUSINESS TYPE” factor. He focuses on key red flags within “BUSINESS TYPES”, including the enhanced due diligence that should be applied to businesses that are simultaneously involved in cross border transactions, that carry out large volumes of value movements, that sell products difficult to externally measure, that offer value transfer systems, and that are unregulated. Using that criteria, he identifies one particular type of business that, although not commonly thought to be a vehicle for money laundering, is an asset to launderers that might corruptly operate such a business.
