The trustee handing the case of New York Ponzi scheme operator Bernard Madoff said he mailed $2.5 billion in checks to 1,230 victims this week. Convicted swindler Madoff is serving a 150-year sentence in a federal prison in North Carolina. With $17.3 billion in losses, the fraud that lasted for more than a decade is often reported to be the largest in history. Court appointed trustee Irving Picard said he sent checks averaging $2 million to some of the victims in the scheme. The smallest check in the batch is for $1,784, while the largest is for $526.8 million, Picard said. With this week\'s distribution of funds, Picard has sent out $3.6 billion to victims, CNNMoney reported Thursday. He has recovered a total of $9.15 billion. With the latest payment, 182 more victims will have recovered their losses in full, bringing the total number of closed claims to 1,074. Another 1,048 claims remain open.
