One of the key components of an effective anti-money laundering (AML) program is to implement adequate customer due diligence (CDD) measures for new accounts. This includes verifying the identity of the party opening the account, determining the beneficial owner(s) of the account, and seeking to determine the source of deposited funds. These measures help the financial institution (FI) to understand the nature and purpose of the customer relationship, assess the risk profile of the customer, and detect and report any suspicious or unusual activity. Documenting the identity of the party opening the account and the beneficial owner(s) of the account also helps the FI to comply with the record-keeping and reporting requirements of the AML laws and regulations, and to cooperate with the authorities in case of investigations or inquiries. Seeking to determine the source of deposited funds helps the FI to prevent the introduction of illicit funds into the financial system, and to identify any discrepancies or inconsistencies between the customer's profile and activity.

International business corporations (IBCs) are entities that are created in jurisdictions that offer low or no taxes, high confidentiality, and minimal regulation. They are often used by individuals and businesses to avoid or evade taxes, conceal assets, and launder money. Some of the risks associated with IBCs are:
They are created in a tax haven. Tax havens are countries or territories that have low or no taxes, lax financial regulation, and high secrecy. They attract IBCs that seek to reduce their tax liabilities, hide their beneficial owners, and evade scrutiny from authorities. Tax havens pose a risk to the global financial system, as they facilitate tax evasion, money laundering, corruption, and illicit financial flows12.
They are established with nominee directors. Nominee directors are individuals who act as the legal representatives of an IBC, but have no actual control or authority over its activities. They are often used to shield the true beneficial owners of the IBC from detection and accountability. Nominee directors pose a risk to the transparency and integrity of the IBC, as they can enable fraud, tax evasion, money laundering, and other criminal activities34.
