Enhanced CDD requires you to obtain and verify the same identity information that is required for standard customer due diligence. In most cases, enhanced CDD requires you to obtain and verify information relating to the source of wealth (SoW) and source of funds (SoF) of your customer.
The requirement to identify and verify SoW and SoF apply to certain high-risk customers, certain transactions and activities, or politically exposed persons (as set out in section 22 and sections 23-26 of the Anti-Money Laundering and Countering Financing of Terrorism Act 2009. In these circumstances, a reporting entity is required to examine the legitimacy (or potential illegitimacy) of the SoW and/or SoF of the customer.
