Bringing $15,000 worth of chips into the casino is a red flag because it could indicate that the customer is trying to avoid the currency transaction reporting (CTR) requirement for cash transactions over
$10,0001. Requesting a wire transfer to an unrelated third party is another red flag because it could indicate that the customer is trying to conceal the source or destination of the funds, or transfer them to a high-risk jurisdiction2.

it describes the organization that a national Financial Intelligence Unit (FIU) should consider becoming a member of, which is the Egmont Group. The Egmont Group is an international network of FIUs that was established in 1995 to facilitate the exchange of financial intelligence and information among its members, and to promote cooperation and coordination in the fight against money laundering and terrorist financing. The Egmont Group currently has 166 member FIUs from different jurisdictions, and provides them with various benefits, such as access to secure communication channels, best practices, training, and technical assistance.
The Egmont Group also works closely with other international organizations, such as the Financial Action Task Force (FATF), the United Nations, and the World Bank, to enhance the global anti-money laundering and counter-terrorist financing (AML/CTF) framework.
The other options are not necessarily organizations that a national FIU should consider becoming a member of, although they may have some relevance or influence on the AML/CTF field. Option B describes the Wolfsberg Group, which is an association of 13 global banks that was formed in 2000 to develop standards and guidance for the financial industry on AML/CTF and other financial crime issues. The Wolfsberg Group is not an organization for FIUs, but rather for financial institutions. Option C describes the Financial Action Task Force (FATF), which is an inter-governmental body that was established in 1989 to set the international standards and recommendations for AML/CTF and to monitor the compliance and effectiveness of its members and other jurisdictions. The FATF is not an organization for FIUs, but rather for governments and policy-makers. Option D describes the Basel Committee, which is a forum of central bank governors and heads of banking supervision authorities from 28 jurisdictions that was established in 1974 to enhance the quality and consistency of banking supervision and regulation. The Basel Committee is not an organization for FIUs, but rather for banking regulators and supervisors.

The risk-based approach (RBA) is an essential foundation of the FATF Recommendations, as it allows countries, competent authorities and financial institutions to adopt a more flexible set of measures to target their resources more effectively and apply preventive measures that are commensurate to the nature of risks, in order to focus their efforts in the most effective way. The RBA is not optional, but a prerequisite for the effective implementation of the FATF Standards. The RBA requires the identification, assessment and understanding of the ML/TF risks to which the countries and FIs are exposed, and the implementation of AML/CFT measures that are proportionate and tailored to those risks. The RBA is not a "zero failure" approach, but a way to mitigate the risks in the most efficient and effective manner.

According to the Basel Committee's paper on Customer Due Diligence for Banks1, banks should review their existing customer relationships on a regular basis, especially for higher risk categories of customers or business relationships. This includes identifying whether the customer or the beneficial owner is a PEP, either at the account opening stage or later, as a result of a change in the customer's circumstances or profile. The paper also states that banks should apply a risk-based approach to determine the appropriate level and type of due diligence depending on the risk profile of the customer or the beneficial owner.
