The trustee liquidating MF Global Holdings Ltd's broker-dealer unit yesterday urged a bankruptcy judge to approve a settlement under which exchange regulator CME Group Inc. would return $160 million to the unit's estate, Reuters reported yesterday. Bankruptcy Judge Martin Glenn expressed no concerns at a hearing about MF Global's $160 million settlement, which has the support of the Commodity Futures Trading Commission. No one else raised objections in court. Trustee James Giddens plans to allocate $130 million of the sum to commodity trader customers who lost money when the MF Global parent company went bankrupt, a controversial decision that had threatened to derail the settlement.
