Rating agencies

Rating agencies, or credit-rating agencies, evaluate creditworthiness. This includes the creditworthiness of corporations, nonprofit organizations and governments, as well as ‘securitized assets’ – which are assets that are bundled together and sold, to investors, as security. Rating agencies assign a letter grade to each bond, which represents an opinion as to the likelihood that the organization will be able to repay both the principal and interest as they become due. Ratings are made on a descending scale : AAA is the highest, then AA, A, BBB, BB, B, etc. A rating of BB or below is considered a ‘junk bond’ because it is likely to default. Many factors go into the assignment of ratings, including the profitability of the organization and its total indebtedness. The three largest credit rating agencies are Moody’s, Standard & Poor’s and Fitch Ratings (FT).
