Misfortune's
Formula: Structured Credit Ratings
Commentary: LIPPER HedgeWorld - Wednesday, September 19, 2007
By Janet Tavakoli, Tavakoli Structured Finance
The rating
agencies, the Nationally Recognized Statistical Rating Organizations
(NRSROs), protest they are misunderstood rather
than miscalculating when it comes to rating structured products.
They would like to claim that the market misapplies ratings by
expecting ratings to indicate market price and liquidity, but
the former are merely symptoms of the real problem. When it comes
to structured products—in particular those involving asset-backed
securitizations and collateralized debt obligations (CDOs)—the
rating agencies failed to apply the most basic of statistical
principals: One must take reasonable steps to understand the
character of the risk one is modeling.
