The Office of Foreign Assets Control ("OFAC") of the U.S. Department of the Treasury is amending the Global Terrorism Sanctions Regulations and the Terrorism Sanctions Regulations (the "TSR") to clarify the scope of prohibitions on the making of donations contained in the underlying Executive orders and that a person whose property and interests in property are blocked pursuant to those programs has an interest in all property and interests in property of an entity in which it owns, directly or indirectly, a 50 percent or greater interest. In addition, OFAC is amending the TSR to add a definition of the term "financial, material, or technological support" and to set at 180 days the maximum term of maturity for instruments in which funds may be invested or held within a blocked interest-bearing account. Finally, OFAC is correcting a clerical error within the Foreign Terrorist Organizations Sanctions Regulations.
