Jeffrey Gundlach, formerly the chief investment officer of TCW who managed $110 billion in assets, was fired by TCW in December 2009. TCW then sued Gundlach, alleging he stole proprietary client information to start his own firm, DoubleLine Capital. Gundlach countersued, claiming he was wrongfully terminated to prevent him from receiving hundreds of millions in future fees. The legal battle represents the culmination of years of tensions between Gundlach and TCW management after the firm was acquired by French bank Societe Generale in 2001.
