“Standard & Poor’s Ratings Services is updating its methodologies and assumptions for rating corporate cash flow and synthetic collateralized debt obligations (CDOs). This update follows our request for comment (RFC), titled “Update To Global Methodologies And Assumptions For Corporate Cash Flow CDO And Synthetic CDO Ratings,” published March 18, 2009. This represents a significant recalibration of our CDO criteria and is intended to enhance the comparability of CDO ratings with ratings in other sectors, such as corporates, municipals, sovereigns, and other areas of structured finance (see “Understanding Standard & Poor’s Rating Definitions,” published June 3, 2009).”
