The U.S. Department of the Treasury Office of Foreign Assets Control (OFAC) administers and enforces economic and trade sanctions based on U.S. foreign policy and national security goals. OFAC publishes lists of individuals and entities that are subject to various sanctions programs, such as the Specially Designated Nationals and Blocked Persons List (SDN List), the Sectoral Sanctions Identifications List (SSI List), and the Foreign Sanctions Evaders List (FSE List). These lists are updated frequently and can be accessed through OFAC's website or other sources12.
The Financial Action Task Force (FATF) is an inter-governmental body that sets standards and promotes effective implementation of legal, regulatory and operational measures for combating money laundering, terrorist financing and other related threats to the integrity of the international financial system. FATF publishes lists of jurisdictions that have strategic deficiencies in their anti-money laundering and counter-terrorist financing (AML/CTF) regimes, and calls on its members and other countries to apply enhanced due diligence or counter-measures to protect themselves from the risks emanating from these jurisdictions. These lists are updated periodically and can be accessed through FATF's website or other sources34.

Explanation
When dealing with correspondent banking clients, banks must evaluate the ownership and management structure of the client in order to assess the risks associated with the relationship. The status of the entity as a state, publicly, or privately held entity, as well as the transparency of the ownership structure, are important factors to consider when assessing these risks. Banks should also take into account the size of the management structure, the regularity of board meetings, and the length of time since the last Wolfsberg Group review in order to determine the risk associated with the correspondent banking relationship.

According to the Anti-Money Laundering Specialist (the 6th edition) study guide, an effective anti-money laundering program should be subject to periodic independent testing by a qualified party, such as an internal or external auditor, a consultant, or a compliance professional1. This ensures that the program is compliant with the applicable laws and regulations, and that it meets the standards of sound risk management and internal controls2. The regulatory authorities, a member of senior management, or the anti-money laundering specialist may not have the necessary expertise, objectivity, or independence to conduct a thorough and unbiased evaluation of the program.
