A politically exposed person (PEP) is a customer who requires the most enhanced due diligence (EDD). This is because PEPs are individuals who hold or have held prominent public positions, such as heads of state, senior politicians, judges, military officers, or directors of state-owned enterprises, and who may pose a higher risk of money laundering, corruption, or bribery due to their influence and access to public funds1. EDD measures for PEPs may include obtaining senior management approval, establishing the source of wealth and funds, and conducting enhanced ongoing monitoring of the business relationship2.
The other customers listed do not necessarily require the most EDD, although they may still present a higher risk of money laundering depending on the circumstances. A resident of a non-cooperative jurisdiction is a customer who lives in a country or territory that has been identified by the Financial Action Task Force (FATF) or other international bodies as having weak or deficient anti-money laundering (AML) standards or posing a threat to the international financial system3. EDD measures for such customers may include obtaining additional information or documentation, applying extra scrutiny to transactions, or refusing to establish or continue the business relationship4. An international business corporation is a customer who operates in multiple jurisdictions and may have complex or opaque ownership structures that can conceal the identity or activity of the beneficial owners or controllers. EDD measures for such customers may include verifying the legal existence and structure of the entity, identifying the beneficial owners and controllers, and understanding the nature and purpose of the business relationship. An established customer is a customer who has a long-standing and regular business relationship with the financial institution and who may have a lower risk of money laundering due to the familiarity and trust that has been built over time. EDD measures for such customers may not be required unless there are changes in the customer's profile, behavior, or risk level.

the results of related audits and examinations are the most useful additional element to report to executive management on a regular basis. Audits and examinations are essential tools to assess the effectiveness and compliance of the anti-money laundering program across the organization. They can identify strengths, weaknesses, gaps, risks, and best practices in the program and provide recommendations for improvement.
They can also help to monitor the implementation of corrective actions and remediation plans. Reporting the results of audits and examinations can help executive management to oversee the performance of the program, ensure accountability, and demonstrate commitment to the anti-money laundering objectives12 References: =

The Office of Foreign Assets Control (OFAC) is a department of the US Treasury that administers and enforces economic and trade sanctions imposed by the US against countries and groups of individuals, such as terrorists and narcotics traffickers. The sanctions can be either comprehensive or selective, using the blocking of assets and trade restrictions to accomplish foreign policy and national security goals. The main purpose of the US Treasury Department for OFAC's extraterritorial reach is to apply these sanctions to any person or entity that is subject to US jurisdiction, or that engages in transactions involving US persons, US dollars, or US goods or services. This way, the US can exert pressure on the targets of the sanctions and prevent them from accessing the US financial system or market. OFAC's extraterritorial reach is authorized by Congressional legislation or presidential emergency powers, and is often based on UN Security Council resolutions or multilateral agreements.

After filing a suspicious activity report (SAR), an investigator should prepare a summary for senior management recommending client off-boarding. This is because client off-boarding is a risk-based decision that requires senior management approval and may involve legal considerations. Informing other local financial institutions about the client, restraining or blocking the client's account(s), or contacting law enforcement directly are not appropriate actions for an investigator to take after filing a SAR, as they may compromise the confidentiality of the SAR, violate privacy laws, or interfere with ongoing investigations.
