According to the FATF Procedures for the Fourth Round of AML/CFT Mutual Evaluations1, jurisdictions that are determined to have strategic deficiencies in their regimes to counter money laundering, terrorist financing, and proliferation financing are subject to the FATF's International Cooperation Review Group (ICRG) process. The ICRG process involves the following actions for such jurisdictions:
* Demonstrate a high-level commitment to swiftly resolve the identified deficiencies in the FATF mutual evaluation report. This commitment should be made in writing to the FATF President and should include an action plan with specific deadlines and milestones to address the deficiencies.
* Report to FATF on the implementation of their progress under the enhanced follow-up mechanism. The FATF will monitor the progress of the jurisdiction through regular reports and on-site visits, and will decide whether the jurisdiction has made sufficient progress to exit the ICRG process or whether further actions are required, such as public statements, counter-measures, or suspension of membership.
The other options are not resulting actions for jurisdictions with strategic deficiencies, as they are either not part of the FATF procedures or not consistent with the FATF's objectives and principles. For example, the FATF does not issue private statements regarding the level of compliance of a jurisdiction, nor does it allow a jurisdiction to appeal for a technical compliance re-rating based on its own criteria. The FATF also does not grant extensions of deadlines for jurisdictions to improve their regimes, as this would undermine the credibility and effectiveness of the mutual evaluation process.

The Egmont Group is a global network of 170 financial intelligence units (FIUs) that facilitate the exchange of information and cooperation among member FIUs to combat money laundering, terrorist financing, and associated predicate offences12. FIUs are national agencies that collect, analyze, and disseminate financial intelligence to relevant authorities3. The Egmont Group supports the implementation of international standardsand best practices for FIUs, provides training and technical assistance, and promotes the development of secure and effective communication channels12.

According to the ACAMS study guide, one of the best practices for dealing with law enforcement inquiries is to verify the identity and authority of the law enforcement officer before providing any information (p. 224).
This is to ensure that the inquiry is legitimate and not a phishing attempt or a breach of confidentiality. The compliance officer should also document the inquiry and the information provided, and consult with legal counsel if necessary. The other options are not appropriate, as they may either violate the law, compromise the investigation, or create unnecessary work.

C: FSRBs play an essential role in identifying and addressing AML technical assistance needs for their individual member countries. The FSRBs are responsible for promoting the effective implementation of the FATF Recommendations at the regional level, including by assisting member countries in identifying technical assistance needs and facilitating the provision of such assistance.
D: FATF and FSRBs are free-standing organizations that share the common goals of combating money laundering and the financing of terrorism and proliferation. The FATF is an intergovernmental body that sets global standards for AML/CFT and promotes their effective implementation, while the FSRBs are regional organizations that work to promote the effective implementation of the FATF Recommendations at the regional level.

A money laundering investigation that involves multiple countries can be challenging due to different legal systems, languages, cultures, and levels of cooperation. Two factors that can assist such an investigation are:
* Law enforcement and other authorities should have access to financial information that is pertinent to the investigation. This can help them trace the flow of illicit funds, identify the perpetrators and beneficiaries, and gather evidence for prosecution. Financial information can be obtained from various sources, such as financial institutions, financial intelligence units, regulators, and international organizations.
* Law enforcement and other authorities should be allowed to establish and utilize joint investigative teams with law enforcement in other countries. This can enhance coordination, communication, and information sharing among the authorities involved, and allow them to pool resources, expertise, and evidence. Joint investigative teams can also facilitate mutual legal assistance and extradition requests.
