The Wolfsberg Principles for Private Banking are a set of guidelines for private banking relationships that aim to prevent and detect money laundering and terrorist financing risks. The Principles state that the bank should conduct additional due diligence on clients and beneficial owners in certain circumstances that may indicate a higher risk of money laundering or terrorist financing. Among the options given, A, B, and C are the correct choices that reflect the circumstances listed in the Principles.
Foreign jurisdictions are countries or territories other than the one where the bank operates or where the client or beneficial owner resides. The Principles state that the bank should conduct additional due diligence on clients and beneficial owners who are connected to foreign jurisdictions, especially those that have weak or inadequate anti-money laundering standards, or that are subject to sanctions, embargoes, or similar measures.
High Risk Countries are countries or territories that are identified by credible sources, such as the Financial Action Task Force (FATF), as having inadequate anti-money laundering standards, or as being a source, transit, or destination of illicit funds. The Principles state that the bank should conduct additional due diligence on clients and beneficial owners who are connected to high risk countries, and apply enhanced measures to mitigate the risks.
High Risk activities are activities that involve clients and beneficial owners whose source of wealth or funds originates from sectors or industries that are known to be vulnerable to money laundering, such as cash-intensive businesses, gambling, arms trade, precious metals and stones, or art and antiquities. The Principles state that the bank should conduct additional due diligence on clients and beneficial owners who are engaged in high risk activities, and verify the legitimacy and origin of their wealth and funds.

The compliance officer should recommend an audit for cash transactions since the last compliance review, as this would help to identify the extent of the problem, the root causes, and the potential risks involved. The audit would also provide evidence for corrective actions and remedial measures to prevent future occurrences of non-compliance. The compliance officer should not recommend terminating or suspending the teller's employment, as this would be premature and disproportionate without a thorough investigation and due process. The compliance officer should not recommend formally reprimanding the branch manager, as this would not address the underlying issues and could create a hostile work environment.
