New York Attorney General Eric Schneiderman filed a civil fraud case against JPMorgan Chase & Co on Monday over mortgage-backed securities originated and sold by Bear Stearns. The JPMorgan complaint was the first action to come out of a working group created by President Barack Obama earlier this year to go after wrongdoing that led to the 2008 financial crisis. JPMorgan, which bought Bear Stearns for $10 a share in March 2008, said in a statement it would contest the allegations. The nature of the investigation of Credit Suisse was not immediately known. However, private parties have filed lawsuits against the bank claiming that it misrepresented the quality of mortgages underlying securities it sold. The U.S. Securities and Exchange Commission subpoenaed mortgage-related documents from Credit Suisse, bond insurer MBIA Inc disclosed in a court filing in May 2011. The New York attorney general's office declined to comment. The Justice Department did not immediately return calls and emails seeking comment.
