5 C.F.R. § 950.505
Each federation, federation member and independent organization applying for participation in the CFC must, as a condition of participation, complete a certification that it is in compliance with all statutes, Executive orders, and regulations restricting or prohibiting U.S. persons from engaging in transactions and dealings with countries, entities or individuals subject to economic sanctions administered by the U.S. Department of the Treasury's Office of Foreign Assets Control (OFAC). Should any change in circumstances pertaining to this certification occur at any time, the organization must notify OPM's Office of CFC immediately. OPM will take such steps as it deems appropriate under the circumstances, including, but not limited to, notifying OFAC and/or other enforcement authorities of such change, suspending disbursement of CFC funds not yet disbursed, retracting (to the extent practicable) CFC funds already disbursed, and suspending or expelling the organization from the CFC.
