Justice Department lawyers want to extract the largest possible penalty from Bank of America after a Charlotte, NC, jury found in October that its Countrywide Financial Corp. division committed fraud when it sold toxic mortgages to Fannie Mae and Freddie Mac in the years leading up to the 2008 financial crisis, according to court papers filed earlier this month.In its successful civil suit against BofA, the DOJ and the Securities and Exchange Commission estimated that the two GSEs lost some $850 million from thousands of loans acquired through CFCs Hustle program between August 2007 and May 2008. BofA acquired Countrywide in 2008 and is liable for the fraud.
