According to the Financial Action Task Force (FATF), a financial institution must take certain steps to fulfill its customer due diligence (CDD) obligations [1][2]. These steps include verifying the customer's identity, understanding the customer's business, and assessing the customer's risk profile. Additionally, the financial institution must verify that the customer is not on any sanction lists, such as the OFAC Specially Designated Nationals list. This step is important to ensure that the financial institution is not doing business with any individuals or entities that are subject to economic sanctions. Other steps include obtaining information on the intended nature of the banking relationship, securing a written declaration from the customer confirming the source of the funds, and identifying shareholders listed on the stock exchange of corporate entities holding fifty percent of the shares.
