A financial-exchange executive says Jon Corzine might have known that MF Global customers' money was transferred earlier than Corzine has admitted.

CME Group Inc. Executive Chairman Terrence Duffy has told a Senate panel that Corzine knew before Oct. 30 about a transfer of $175 million in the form of a loan to a European affiliate.

Corzine has testified that he didn't know that any customer money was missing until Oct. 30, the day before MF Global filed for bankruptcy protection. MF Global traded heavily on exchanges managed by CME Group.

Duffy says he's referred the matter to the Justice Department and to regulators. He says he received the information this week from CME Group attorneys who are investigating the matter.
