Applies, 180 days after the enactment of the National Defense Authorization Act for Fiscal Year 2012 (P.L. 112-81), specified prohibitions and conditions on U.S. correspondent or payable-through accounts of foreign financial institutions that engage in petroleum or petroleum product transactions with, or provide related financial services to, the NIOC or NITC if the President determines that there is a sufficient supply of non-Iranian petroleum and petroleum product sources to permit purchasers of Iranian petroleum and petroleum products to reduce significantly their purchases from Iran.
