The man known as the bond king, Bill Gross, is suing the company that he built into one of the largest asset managers in the world, providing his own colorful version of an ugly feud that led to his departure last year. The lawsuit, filed on Thursday, represents a bold effort by Gross to repair the damage that was done to his reputation in the year before and after he was fired from Pimco. News media reports have portrayed Gross’ departure as a product of his erratic and domineering behavior at the firm he helped found in 1971. Gross is seeking “in no event less than $200 million” from Pimco for breach of covenant of good faith and fair dealing, among other causes of action.
