“While companies are developing more comprehensive criteria, the standards are far from consistent. The reasons for the inconsistencies are numerous, but of greatest concern is the bias of ratings and the lack of public disclosure about the criteria and standards used in making those ratings.”

I see the ratings’ firms more like equity analysts — who vary (often greatly) in their analytical methods and conclusions.
