According to the news, Leeson

How do you blow 1 billion? With that much money, you could buy every jewel in Tiffany’s, collect a small fleet of 747s…[24A]or bankrupt a vulnerable bank. That’s what Nicholas Leeson apparently did. The 28-year-old trader for British investment house Barings PLC in Singapore staked more than 1 billion of the company’s money last winter on Japanese derivatives, and got tsunamied. For weeks he tried to recoup his mounting losses with double-or-nothing bets and doctored bookkeeping. He was arrested in Frankfurt on his way to London. Germany extradited him to Singapore last month, where he was sentenced to 6. 5 years in prison. [25D] Leeson is appealing.
