It is unclear what type of assets Goldman bought from MF Global, but the securities were worth hundreds of millions of dollars, the former employees said. The sources spoke on the condition of anonymity. The Wall Street Journal previously reported that George Soros' fund was a buyer of securities sold by MF Global, scooping-up some of its European sovereign debt at a deep discount. Panic among investors and clients about MF Global's $6.3 billion bet on European sovereign bonds led to its demise. Corzine, who was CEO of MF Global at the time of the collapse, headed Goldman Sachs from 1994 to 1999 before being ousted after a power struggle with co-CEO Henry Paulson.
