On October 7, OFAC updated its Frequently Asked Questions (FAQs) relating to the Listing of Certain U.S. Sanctions under the Joint Comprehensive Plan of Action (JCPOA). In addition to adding three FAQs related to due diligence (see M.10 through M.12), OFAC amended two FAQs (C.7 and C.15) regarding Financial and Banking Measures and one FAQ (K.19) related to Foreign Entities Owned or Controlled by U.S. Persons. FAQ M.10 clarifies that while “[i]t is not necessarily sanctionable for a non-U.S. person to engage in transactions with an entity that is not on the SDN List but that is minority owned, or that is controlled in whole or in part, by an Iranian or Iran-related person on the SDN List,” it is recommended that persons engaging in such transactions exercise caution to ensure that they do not involve Iranian or Iran-related persons on the SDN List. FAQs M.11 and M.12, respectively, address (i) due diligence expectations related to the screening of potential Iranian counterparties; and (ii) the circumstances under which OFAC expects a non-U.S. financial institution to repeat the due diligence their customers have already performed on an Iranian customer.
