The trustee in charge of MF Global Holdings Ltd. said that he will allow the U.S. government and the trustee unwinding the company's failed brokerage, MF Global Inc., to go further back in their investigation into the company's books concerning segregated funds, which still have a reported shortfall of more than $1 billion, Dow Jones Newswires reported yesterday. Trustee Louis J. Freeh on Wednesday said that he will waive attorney-client privilege and turn over documents and other information about MF Global's segregated accounts from the period of July 1, 2011, until the company's Oct. 31, 2011, bankruptcy filing. Previously, he had agreed to open MF Global's books for the two-week period leading up to its bankruptcy. A judge will consider approving the stipulation at an Oct. 11 hearing.
