The Miami Herald is reporting that the Cuban government used the Panamanian law firm Mossack Fonseca to create at least 25 corporations registered in the British Virgin Islands, Panama and the Bahamas. Mossack Fonsenca, and its clients, have come under immense scrutiny since the leak of hundreds of thousands of pages of the firm's files, which have been come known as the "Panama Papers", revealed elaborate tax shelters used by some of the world's wealthiest individuals and organizations.

In a June 7, 2016 report, the Miami Herald alleges that at the Cuban government used Mossak Fonseca to set up numerous corporations and then used these off-shore entities to conduct business, including numerous exchanges of oil for Cuban goods, which was prohibited by the US embargo on Cuba. Although the Panamanian firm's aid or involvement with the Cuban government is likely beyond the jurisdiction of US officials, the potential ramifications for US corporations who may have dealt with the alleged off-shore Cuban entities is uncertain.

Under Cuban Assets Control Regulations (31 C.F.R. Part 515), an entity can potentially avoid penalties if it is able to demonstrate that is did not willfully violate the regulations, had no reason to know or suspect that it was involved in a prohibited transaction, and the entity reported the prohibited transaction to the Office of Foreign Assets Control (OFAC) as soon as it became aware of the violation. (31 C.F.R. 515.203). It is also possible that individual transactions may have been authorized pursuant to specific licenses issued by OFAC. The critical issue, therefore, is whether any US entities knew or should have known that they were dealing with an entity connected to the Cuban government. As investigations of the Panama Papers continue, correspondence contained therein could potentially demonstrate knowledge by US companies about the Cuban connections of the off-shore entities identified in the Miami Herald report.

US companies who may have engaged the Cuban off-shore entities should be proactive and investigate what, if any, contact they may have had with these entities as self-reporting any transactions to OFAC is a necessary first step in cooperation. Depending on the size of the organization, using a third-party investigator, such a law firm, may ensure the preservation of documents and, in turn, the integrity of the investigation should an investigation by OFAC become necessary.
