The rating agency said more than 60 CDO transactions are still on watch for potential downgrade, with a resolution due on or before Nov. 21.

On Monday, nearly $20 billion worth of transactions was cut from investment-grade to junk, said Kevin Kendra, managing director at Derivative Fitch.

The problem is that there are many assets that simply have no buyers, at least not at a non-bankruptcy inducing price. As such, they are illiquid, and valuless.
