Mossack Fonseca & Co. was a Panamanian law firm and corporate service provider.[3][4] At one time it was the world's fourth-largest provider of offshore financial services. From its establishment in 1977 until the publication of the Panama Papers in April 2016, the company remained mostly obscured from public attention, even though it was a major firm in the global offshore industry and acted for approximately 300,000 companies. Prior to its dissolution, the company employed roughly 600 staff members spread across 42 countries.[5]
The firm received worldwide media attention in April 2016, when the International Consortium of Investigative Journalists published information about the financial dealings of the firm's clients in the Panama Papers articles. These articles were the result of analyzing an enormous cache of documents, dated from 1970 and 2015, which were leaked to the news media,[6]
