Paris , France ( CNN ) -- Trader Jerome Kerviel was found guilty of all charges Tuesday for betting 50 billion euros ( $ 61 billion ) of a French bank 's money without its knowledge . The judge sentenced Kerviel to a five-year sentence but suspended two years of it , meaning he will serve three years in prison . He was also ordered to pay 4.9 billion euros ( $ 6.75 billion ) in damages to the bank . Kerviel was not immediately jailed and left court after the verdict and sentencing . Kerviel , a former employee of French bank Societe Generale , went on trial in June on charges of forgery , breach of trust and unauthorized computer use . The banks says the unhedged bets cost it almost $ 6 billion . The damages he was ordered to pay was far more than prosecutors had asked . It was thought before the verdict that Kerviel would face a fine of as much as 375,000 euros ( about $ 460,000 ) . Kerviel 's lawyer , Olivier Metzner , called the verdict `` unreasonable '' and said he planned to appeal . He has 10 days in which to do so . Kerviel had pleaded guilty to the charge of computer abuse , but Metzner had asked jurors in his closing arguments to acquit his client of the charges of breach of trust and forgery . Metzner previously told CNN that Kerviel 's behavior was strongly influenced by the environment at Societe Generale . `` The banks are the ones to blame for the banking system and the systematic economic crisis , not Jerome Kerviel , '' he said . Kerviel traded European index futures for the bank . He was the only person ever charged in the case , despite claiming he did everything with the knowledge of his superiors . `` I am convinced the criminal file is full of elements proving that my superiors knew and covered for me . At least I should n't be the only one in the dock , '' he told CNN after the release of his memoirs , `` Trapped in a Spiral : Memoirs of a Trader '' in which he pleads his innocence . `` During three years , these managers earned colossal amounts of money out of bonuses based on the ever-growing results that I was making for the bank , '' he said . Societe Generale , which said it discovered the losses in January 2008 , said that at no time were supervisors aware of Kerviel 's alleged unlawful activities . CNN 's Saskya Vandoorne contributed to this report .
