Three months after its massive trading scandal, France's number-two bank has a new CFO.

Didier Valen will take on the CFO position at Societe Generale, the French bank that was hit with a $7.5 billion loss this January from rogue deals made by junior trader Jérôme Kerviel.

Valet, 40, replaces former CFO Frédéric Oudéa, who was promoted to chief executive of France's second largest bank last month.

He has been with Societe Generale since 2000 in the company's corporate and investment banking division where he served as head of the European banking team in the equity research department.

In 2003, Valet took a position as head of investor relations. He was promoted to head of strategic performance management of Societe Generale Group's finance and development division in March 2007.

Previously, he worked in research for Banque Indosuez's banking and insurance departments and covered France's banking sector as a research analyst at Dresdner Kleinwort Benson.

Societe Generale's rogue trader Kerviel was released from prison in March but is still being investigated for computer abuse, breach of trust and falsification. Last month, he was hired to work for a computer consulting firm.
