Bearer shares have been banned in many offshore finance centres but not in Panama, which is one of the reasons that the country is ranked extremely low on the OECD rank of tax havens.
A bearer share is basically a piece of paper that shows that you own a piece of the company, but is the only record of ownership and, as a result, allow owners to hide their assets. The BBC published a handy guide to bearer shares here.

The family said that the Panama company that the files referred to was an "inactive" company that never had any funds or active current accounts.
In a statement it said: "The Messi family wants to make clear that Lionel Messi has not carried out any of the acts attributed to him, and accusations he created a ... tax evasion plot, including a network of money-laundering, are false and insulting," AFP reported.

At least eight top Chinese officials and associates, including President Xi Jinping's brother-in-law Deng Jiagui, are linked to offshore deals, IBTimes UK reports. They hid millions of dollars, according to an investigation of 11.5 million documents leaked from one of the world's largest offshore law firms.
As IBTimes UK has already reported, Jürgen Mossack, one of Mossack Fonseca's founding partners, was the son of a former SS soldier turned CIA spy.

Ramon Fonseca, a founder and director of Panama-based law firm Mossack Fonseca has told Reuters that the leak is part of "an international campaign against privacy".
"We're dedicated to making legal structures which we sell to intermediaries such as banks, lawyers, accountants and trusts, and they have their end-customers that we don't know," said Fonseca.
"We believe there's an international campaign against privacy. Privacy is a sacred human right (but) there are people in the world who do not understand that and we definitely believe in privacy and will continue working so that legal privacy can work," he said.
Fonseca has said in a separate statement to the Guardian newspaper, which has been given access to the Panama Papers by the Consortium of Investigative Journalists:
"It appears that you have had unauthorized access to proprietary documents and information taken from our company and have presented and interpreted them out of context."
