June 26 (Bloomberg) -- Holders of some investment-grade portions of collateralized debt obligations backed by subprime mortgages will lose all of their money, according to Bill Gross, manager of the world's biggest bond fund.
Bankers and money managers bundle securities into CDOs and divide them into slices with credit ratings as high as AAA from Standard & Poor's and Aaa by Moody's Investors Service.
With subprime loan defaults at 7 percent, buyers of the BBB pieces of CDOs stand to lose their entire investment, said Gross, chief investment officer at Pacific Investment Management Co. Gross manages the $103 billion flagship PIMCO Total Return Fund in Newport Beach, California.
``AAA? You were wooed Mr. Moody's and Mr. Poor's by the makeup, those six-inch hooker heels and a `tramp stamp,''' Gross said in his monthly commentary posted on Pimco's Web site today. ``Many of these good looking girls are not high-class assets worth 100 cents on the dollar.''
Subprime mortgages are loans made to borrowers with poor or limited credit histories, or high debt burdens.
Defaults on subprime loans will ``grow and grow like a weed in your backyard tomato patch'' and if total losses reach 10 percent, CDO slices rated A may also ``face the grim reaper,'' Gross said.
At least 60 mortgage companies have halted operations, gone bankrupt or sought buyers since the start of 2006, according to Bloomberg data. Irvine, California-based New Century Financial Corp. and ResMae Mortgage Corp. of Brea, California, were forced into bankruptcy.
