WASHINGTON D.C., June 13, 2012 Jamie Dimon, Chairman and CEO of JPMorgan Chase, testifies before the U.S. Senate Banking, Housing and Urban Affairs Committee during a hearing titled ”A Breakdown in Risk Management: What Went Wrong at JPMorgan”, in Washington D.C., capital of the United States, June 13, 2012. The recent trade loss of more than 2 billion U.S. dollars presented by JPMorgan Chase’ Chief Investment Office (CIO) resulted from the company’s ineffective risk control system, said Dimon on Wednesday. The huge trade loss of JPMorgan has increased concerns that the biggest banks still pose risks to the U.S. financial system, even the financial crisis has evolved for more than three years.(Xinhua/Zhang Jun) (Credit Image: © Zhang Jun/Xinhua/ZUMAPRESS.com)
