Lehman Brothers Holdings Inc. is seeking to question Bruno Iksil, the former JPMorgan Chase & Co. trader known as the London Whale, about losses Lehman says spurred unnecessary collateral calls that helped force it into bankruptcy, Bloomberg News reported yesterday. JPMorgan in May disclosed billions of dollars in losses by London-based Iksil, who got his nickname because his positions were so big. Lehman, which has been fighting JPMorgan over $8.6 billion since 2008, said in a court filing yesterday that Iksil may have knowledge of the role JPMorgan's chief investment office played in managing exposure to Lehman. Lehman, which is gathering money to pay creditors an average of 18 cents on the dollar, said that it realized Iksil could help it after JPMorgan disclosed "risk management failures." Iksil was "central" to a dispute with JPMorgan over valuing derivatives, New York-based Lehman said.
