The Office of Foreign Asset Control (OFAC), also an agency of the U.S. Department of the Treasury, as part of its enforcement efforts, publishes a list of individuals and companies owned or controlled by, or acting for or on behalf of, targeted countries. It also lists individuals, groups, and entities, such as terrorists and narcotics traffickers designated under programs that are not country-specific. Collectively, such individuals and companies are called “Specially Designated Nationals” or “SDNs.” Their assets are blocked and U.S. persons are generally prohibited from dealing with them. OFAC risk is great at MSBs and must be addressed.
