Settlements between parties with completing claims in the liquidation of MF Global could speed up payment to customers of the collapsed brokerage, with one agreement potentially freeing up as much as $600 million for U.S. customers. Two separate agreements were announced on Saturday One is between James Giddens, the bankruptcy trustee overseeing the liquidation of MF Global’s main brokerage unit, and Richard Heis, who is overseeing the liquidation of the company’s United Kingdom operations. Giddens and Heis agreed to resolve all claims between the two corporate entities.
