Former Societe Generale trader Jerome Kerviel was sentenced to three years in jail by a Paris court on Tuesday for his role in a trading scandal and ordered to pay the French bank 4.9 billion euros ($6.8 billion), Reuters reports.
The verdict came as a victory for SocGen, which always maintained Kerviel acted alone and without the sanction of his managers at the bank.
SocGen had sought payment of damages for the money it lost unwinding the trader's risky market bets in 2008.
Kerviel's lawyer Olivier Metzner said he would immediately appeal the verdict, which he said was 'senseless' and cleared the bank of all blame.
Kerviel was given a total prison sentence of five years, two years of which were suspended.
SocGen's lawyer Jean Veil anwers a journalist's question at the end of the verdict.
The payment to SocGen equates to 3.2 percent of France's central government deficit for 2010, the GDP of Monaco or 16 percent of the French bank's market value.
Kerviel is currently paid 2,300 euros a month as a technology consultant.
A SocGen spokeswoman said the amount awarded showed clearly 'the exceptional damage suffered by the bank and its employees.'
In sentencing, the judge told Kerviel knew exactly what he was doing in overstepping his remit and that he sought to hide his trading positions.
