On December 15, OFAC updated the Frequently Asked Questions Relating to the Lifting of Certain U.S. Sanctions Under the Joint Comprehensive Plan of Action, clarifying two FAQs regarding the re-imposition of sanctions in the event of a “sanctions snapback.” Among other things, the revised guidance clarified that the U.S. will not retroactively impose sanctions for activity considered legitimate during the time of the transaction, but that activity would have to immediately halt because the agreement does not grandfather existing contracts. In addition, OFAC explained that the U.S. would provide non-Iranian foreigners a 180-day period to wind down operations that were authorized prior to a snapback. The FAQ-guidance also explained that if a snapback of sanctions were to result in the revocation of licenses, the U.S. government would provide a 180-day wind-down period for those deals, and non-Iranian foreigners could receive repayment from Iranians for goods and services provided prior to a snapback under the terms of an existing contract.

Separately, OFAC issued amended license General License J-1, regarding foreign flights to Iran, to also authorize flights that involve code-sharing agreements. A code-share is a marketing arrangement in which an airline places its designator code on a flight operated by another airline, and sells tickets for that flight. GL J-1 is effective as of December 15 and replaces and supersedes General License J in its entirety.
