MF Global Ltd., the world’s largest broker of exchange-traded derivatives, lost $71.1 million, or 59 cents per share, in its fiscal fourth quarter, compared with a profit of $76.1 million, or 73 cents per share, a year ago, Bloomberg reported. It also announced it would sell as much as $300 million in equity securities to a J.C. Flowers & Co. affiliate to pay off debt.

The Bermuda-based company has $350 million in debt due in June and $1.05 billion that is due in December, according to a Feb. 13 filing. With its investment in MF Global, J.C. Flowers will be able to appoint two directors to MF Global’s board of directors. MF Global also plans to use $350 million from a five-year revolving loan to pay down part of its bridge loan and said it has tightened risk controls after it reported a $141.5 million trading loss in February.

American International Group Inc. CEO Martin Sullivan also announced today that his company would raise $20 billion, 60 percent more than it originally said it needed to cover further write-downs. The world’s largest insurer by assets raised around $13 billion last week by selling common stock and units that can convert into shares and is in the process of selling hybrid bonds.

On May 9, AIG said it became concerned about its capital reserves after a record $7.81 billion loss in the first quarter. According to Bloomberg data, banks and securities firms have raised or intend to raise more than $260 billion since July to replenish capital depleted by the subprime mortgage market collapse.
