The Office of Foreign Assets Control (OFAC), Department of the Treasury, implements and enforces financial and trade sanctions. FAC has the authority to include within the definition of the sanctioned government those individuals and entities that FAC has determined are owned by, controlled by, or acting directly or indirectly on behalf of the target government. Parties so identified are known as Specially Designated Nationals or SDNs. In practice, an SDN is a target government body, representative, intermediary, or front (whether overt or covert) that usually is located in a third country and functions as an extension of the sanctioned government. An SDN may also be a third-party company that otherwise becomes owned or controlled by the target government or that operates on its behalf. No criminal linkage is necessary. Ownership by, control by, acting on behalf of, or profiting from trade with the target government or country would suffice to qualify a person for designation.
