Regulators have subpoenaed Goldman Sachs ( GS) and Morgan Stanley ( MS) for information related to subprime and other residential mortgages, the two firms acknowledged in annual reports filed Tuesday. The two firms did not specify which agencies had subpoenaed or requested documents, but said they were cooperating with the probes, in the form 10-Ks filed with the Securities and Exchange Commission. Morgan Stanley said "certain regulatory and governmental entities" had requested information about "the origination, purchase, securitization and servicing of subprime and non-subprime residential mortgages and related issues." Goldman said "various governmental agencies and self-regulatory organizations" had requested information about "subprime mortgages, and securitizations, collateralized debt obligations and synthetic products related to subprime mortgages." The SEC and several state regulators, including New York Attorney General Andrew Cuomo, have pressed Wall Street firms amid the housing bubble's burst and resulting mortgage meltdown over their involvement in the process of originating, packaging and selling loans.
