Mark Cuban is 55 years old, owns the National Basketball Association’s Dallas Mavericks, Landmark Theatres, and Magnolia Pictures, and is the chairman of the HDTV cable network AXS TV. He is also a “shark” investor on the television series Shark Tank. In 2011, Cuban wrote an e-book, How to Win at the Sport of Business, where he records his life experiences in business and sports.

On October 16th, Cuban was cleared by a Texas jury of using a private tip to avoid a big loss on his 2004 sale of Internet company shares. Cuban lashed out at the U.S. government and lead prosecutor Jan Folena after the judgement, saying the government had tried to bully him. Cuban claimed that Folena “stood up there and lied” when she read the nine-membered jury’s decision. Cuban was accused by the U.S. Securities and Exchange Commission of trading on non-public information when he sold his 600,000 shares in Internet search company Mamma.com – worth $7.9 million – and avoided a $750,000 loss. The lawsuit was brought against Cuban in November of 2008 by the SEC but a judge dismissed it in 2009. But, in 2010 it was brought back up again by an appeals court.

Cuban refused to settle the case and went on trial, even though he said on Wednesday that he had spent more on fees for lawyers than the possible fines for admitting to insider trading. His lawyers said he could have faced up to $2 million in fines. At the two-week trial, prosecutors argued that he sold his stake soon after learning from Mamma.com Chief Executive Guy Faure that the Montreal-based company was planning a private placement that would weaken his holdings in the company. Cuban testified during the two-week trial that there were many reasons for selling his shares. At the end, Mark Cuban was cleared but his defense lawyer Stephen Best said the case never should’ve been brought to trial in the first place.
