An investigation into the mortgage crisis by New York State prosecutors is now focusing on whether Wall Street banks withheld crucial information about the risks posed by investments linked to subprime loans.
Reports commissioned by the banks raised red flags about high-risk loans known as exceptions, which failed to meet even the lax credit standards of subprime mortgage companies and the Wall Street firms. But the banks did not disclose the details of these reports to credit-rating agencies or investors.
The inquiry, which was opened last summer by New York's attorney general, Andrew M. Cuomo, centers on how the banks bundled billions of dollars of exception loans and other subprime debt into complex mortgage investments, according to people with knowledge of the matter. Charges could be filed in coming weeks.
