Credit Ratings
Credit rating agencies assess the relative credit risk of specific debt securities or structured finance instruments and borrowing entities (issuers of debt),[51] and in some cases the creditworthiness of governments and their securities. A municipal security's credit rating is the grade a rating agency assigns to indicate the risk of default and, in some cases, takes into consideration the potential loss to investors in the event of default.
