Enhanced due diligence (EDD) is a set of additional measures that must be applied by financial institutions (FIs) in higher-risk situations, such as when dealing with customers or transactions from high-risk third countries, customers who are politically exposed persons (PEPs), or customers who present a higher risk of money laundering or terrorist financing. EDD may include obtaining more information on the customer’s identity, source of funds, source of wealth, business relationships, and purpose of the transaction, as well as conducting more frequent and intensive ongoing monitoring of the customer’s activities.
However, EDD may be bypassed for certain situations where the risk of money laundering or terrorist financing is low, and where the customer is subject to adequate supervision and regulation in the EU or the US. According to the CAMS Study Guide - 6th Edition1, one such situation is when on-boarding a casino that is part of an international hotel chain, provides less than 50% of overall revenue and that fully complies with group-wide policies and procedures. This is because such a casino is likely to have a low risk profile, as it is not the main source of income for the hotel chain, and it adheres to the same standards and controls as the rest of the group. Therefore, EDD may not be necessary for this situation, and the FI may apply simplified due diligence (SDD) instead.
The other situations listed in the question are not eligible for bypassing EDD, as they involve higher-risk factors, such as dealing with customers or entities from high-risk third countries, customers with complex ownership structures, or customers who are PEPs. These situations require FIs to apply EDD measures to mitigate the risk of money laundering or terrorist financing.
