Madoff's money makers: Half who profited in Ponzi scheme face 'clawbacks'

Not all of Bernard Madoff's investors lost money. In fact, bankruptcy trustee Irving Picard found that about 50 percent of his active clients withdrew more than they invested. Now, those who made a profit could be asked to pay some of that money back under "clawback" laws.

In a court filing, Madoff prosecutors said, "Nearly 50 percent of the active customers sustained a net loss. Approximately 50 percent of the active customers did not sustain a net loss, in that they withdrew more from their BLMIS [Bernard L. Madoff Investment Securities] accounts than they contributed."
