A firm has an existing client who is the head of a foreign state.

A client who is the spouse of the head of a foreign state is classified as a Politically Exposed Person (PEP). Firms are required to undertake enhanced due diligence (EDD) for PEPs and their immediate family members due to the increased risk of corruption, money laundering, or misuse of public funds.

Simplified (A): This applies to low-risk clients, not PEPs.

Standard (B): Standard due diligence is insufficient for PEPs or their relatives.

Additional (D): This term is not a formal category under anti-money laundering (AML) regulations.
