PANAMA CITY, PANAMA - APRIL 07: A sign is seen in a parking lot next to the building that houses the law firm Mossack Fonseca & Co on April 7, 2016 in Panama City, Panama.  The law firm, which specializes in setting up offshore companies, is at the center of an international scandal and continues to maintain it has broken no laws and that all its operations were legal. A report by the International Consortium of Investigative Journalists referred to as the 'Panama Papers,' based on information anonymously leaked from Mossack Fonesca, indicates possible connections between people setting up the offshore companies and money laundering.
