JPMorgan Chase & Co. has reached a $546 million settlement with the trustee liquidating the failed broker-dealer unit of MF Global Holdings, a court filing showed, an amount that will help repay the brokerage's customers, Reuters reported yesterday. As part of a settlement reached with James Giddens, the trustee who is tasked with liquidating MF Global Inc., JPMorgan will pay $100 million that will be made available for distribution to former MF Global customers. JPMorgan will also return more than $29 million of the brokerage's funds held by the bank, while releasing claims on $417 million that was previously returned to Giddens.
