Bernard Madoff victims who withdrew more money from the con man’s firm than they invested — and were slated for no recovery — asked to be excluded from JPMorgan Chase & Co.’s $543 million settlement of lawsuits over the fraud so they can sue the bank on their own, Bloomberg News reported yesterday. A group of 193 investors said in a court filing on Tuesday that the accord between JPMorgan and Irving Picard, the trustee liquidating Madoff’s defunct company, doesn’t cover “net winners.” They asked for court permission to not be part of the settlement. The group’s lawyer, Helen Davis Chaitman of Becker & Poliakoff LLP in New York, said she intends to file a new lawsuit on behalf of these and other victims who say they were harmed in Madoff’s $17 billion Ponzi scheme, even though they didn’t lose their principal.
