The trustee for MF Global Holdings Inc.'s brokerage unit said he has received $168 million in cash from JPMorgan Chase & Co, which had been the commodities and futures brokerage firm's main bank prior to its October bankruptcy, Reuters reported on Friday. James Giddens, the trustee for the MF Global Inc. unit, said that the money represents proceeds of excess collateral that the largest U.S. bank held when the unit began to liquidate. He said that the payment will help his efforts to return money to former MF Global customers, and that he remains in talks with JPMorgan on other claims. An estimated $1.6 billion of customer funds has disappeared from MF Global, which had been run by Jon Corzine, a former New Jersey governor and senator.
