PARIS, February 13 - RAPSI. Rogue trader Jerome Kerviel, who was convicted in 2010 on counts of breach of trust, fraudulent entry into an automated processing system, forgery, and use thereof, has filed a claim in the Paris labor court against his former employer Societe Generale (SocGen) seeking the same amount he was fined for his indiscretions - 4.9 billion, the Telegraph (UK) reported Tuesday.

The report quoted Kerviel as having said during his trial that the bank's decision to fire him after investigations got underway in 2008 "implied that there was the intention on [his] part to destroy the company, which was never the case and which was proven."

Kerviel was hired in 2000 as an assistant trader for SocGen. In 2005, he was promoted to the position of trader, and assigned to the Delta One Listed Products desk. Office policy dictated against the Delta One desk taking any risks totaling in excess of 125 million Euros. Kerviel failed to adhere to the policy, once going so far as to "take totally exorbitant extraday positions in 2008 that reached 49 billion," according to investigative materials uploaded to SocGen's website.

Kerviel is quoted in the materials as admitting, "Often, in the morning... I received, as did my bosses, notification of major exposures in some of my portfolios. I then entered a fictitious transaction without informing my bosses to conceal these open positions."

Kerviel initially cast himself as a scapegoat, claiming as his 2008 investigation wrapped that his superiors had covered his transactions for years. Still, the number of lies and half-truths that surfaced when investigators combed through his email transactions, paired with the fact that he had admittedly failed to speak directly with his superiors about key transactions militated against him in this regard.

The breach of trust charge is based on Kerviel's taking of extraday positions in contravention of the Delta One 125 Euro cap. The fraudulent entry of data into an automated system charge is based on the fictitious entries Kerviel made in order to cover his tracks. The forgery and use thereof charges are based on Kerviels fabrication of false emails.

In addition to the 4.9 billion fine, Kerviel was sentenced to five years in prison, though two of the five years were suspended, according to the AFP. In late October Kerviel appealed the ruling, but to no avail.

Afterward, SocGen lauded the verdict, proclaiming, "The ruling of the Paris Court of Appeals confirms the guilt of Jerome Kerviel in the massive fraud of which the bank and its employees were victims, in line with the findings of all legal proceedings conducted up to this point, and clearly establishes that his fraudulent activities were committed without the bank's knowledge."
