Star Los Angeles money manager Jeffrey Gundlach has fired a counter-suit at his former employer, TCW, claiming that the firm owes him a whopping $1.25 billion in back pay and future earnings.

Gundlach’s 24-year career at TCW came to an end when the firm, now owned by French bank Société Générale, ousted him on Dec. 4. A number of high-profile employees followed the top fixed-income manager to a rival firm he founded, DoubleLine.

Gundlach is suing TCW for breach of contract and related “misconduct arising from firing,” the cross-complaint filed today reads. The suit claims that TCW agreed to share with Gundlach and his team a predetermined percentage of the management fees and performance fees generated on the TCW funds his group managed.

But instead TCW “hatched a scheme to deprive Gundlach and his group of this lucrative compensation package and to confiscate the huge future fees that would be generated as the result of the skill and hard work of Gundlach and his group,” the documents say.

DoubleLine’s suit comes nearly a month after TCW filed a lawsuit against Gundlach and his new company, claiming that he stole proprietary information and that pornographic videotapes and drug paraphernalia were found in one of the his old offices outside of L.A.
