JPMorgan, Goldman Keep Italy Risk in Dark

``JPMorgan Chase & Co. and Goldman Sachs Group Inc., among the world's biggest traders of credit derivatives, disclosed to shareholders that they have sold protection on more than $5 trillion of debt globally... As concerns mount that those countries may not be creditworthy, investors are being kept in the dark about how much risk U.S. banks face from a default. Firms including Goldman Sachs and JPMorgan don't provide a full picture of potential losses and gains in such a scenario, giving only net numbers or excluding some derivatives altogether.''
