SEC Looks at Securities Firms' Subprime Assets

The SEC is examining the books of the major securities firms and banks to make sure that they are not hiding losses in subprime-mortgages, according to the Wall St. Journal.  The concern is that they may not be using consistent methods in marking down the value of subprime assets and may not be marking down their own portfolios as aggressively as the portfolios held by customers such as hedge funds.  WSJ, Seeking Hidden Losses,Regulators Comb Books Of Wall Street Titans.
