ATP Oil & Gas Corp., the Gulf of Mexico oil producer that filed last week for bankruptcy, was given preliminary approval by a judge for $618 million in financing, Bloomberg News reported today. Bankruptcy Judge Marvin Isgur in Houston yesterday gave interim approval to the financing from Credit Suisse Group AG and other lenders after requiring changes to some terms. The bankruptcy financing provides $250 million in new money and refinances $367.6 million in debt, according to court papers. Lenders include Credit Suisse, Fortress Credit Opportunities I LP and MSD Credit Opportunity Master Fund LP. ATP said that it plans to initially borrow as much as $80 million in new money, and it will return to court for final approval of the loan.
