What happens Monday? The International Consortium of Investigative Journalists (ICIJ) will release to the public a searchable database of documents that reveals the details of more than 200,000 offshore entities and the people in more than 200 countries and territories connected to those accounts.

What are the Panama Papers? The largest leak – the unauthorized disclosure of confidential information – ever, exposing data about secret offshore companies. The Panama Papers, as they have been called, are 11.5 million documents belonging to Panamanian law firm Mossack Fonseca. The nearly 40 years' worth of documents show how the firm helped some wealthy people set up offshore firms, often used to hide assets and avoid taxes and sanctions.
Named in the documents: Owners of offshore companies include 140 politicians, including 12 current and former political leaders; billionaires; sports stars; drug smugglers; mafia members; also at least 33 people and companies blacklisted by the U.S. government because of evidence of their involvement in wrongdoing, such as doing business with Mexican drug lords or with rogue nations such as North Korea and Iran.
What is Mossack Fonseca? Panamanian law firm, considered the world's fourth-largest provider of offshore services.
Law firm response: Mossack Fonseca has denied any wrongdoing and said it was not the source of the leak.
Who leaked the information? No details regarding the source's identity or gender have yet been released, but source calls self "John Doe."
When did this begin? John Doe contacted the German newspaper Süddeutsche Zeitung more than a year ago, offering encrypted internal documents from Mossack Fonseca.
What happened with documents? Süddeutsche Zeitung and the ICIJ joined forces to analyze the data. Over the past year, nearly 400 journalists from more than 100 media organizations in over 80 countries have taken part in researching the documents.
VOA's Zimbabwe Service was a reporting partner with the ICIJ. Reporter Ray Choto focused on documents that alleged Zimbabwe's leading platinum mining firm, Zimplats Holdings, used an offshore company to pay management salaries without the knowledge of the Reserve Bank of Zimbabwe and in violation of exchange control laws.
