rating agencies Credit Rating AgencyA company that provides investors with assessments of an investment's risk. The issuers of investments, especially debt securities, pay credit rating agencies to provide them with ratings. A high rating indicates low risk and may therefore encourage investors to buy a security. Additionally, banks may only invest in securities with a high rating from two or more credit rating agencies. The SEC recognizes 10 firms as credit rating agencies; Fitch, S&P, and Moody's are the three most prominent. However, the methods of credit ratings agencies have been subject to criticism. For example, most agencies gave high-risk mortgage-backed securities top ratings until they defaulted at the collapse of the housing bubble.
Rating ServiceA company that evaluates preferred stocks and debt securities based on the likelihood of default.

Companies issuing new preferred stocks or debt securities pay one or more of the ratings services to have their securities rated. Banks are not allowed to invest in securities with ratings below a certain level.
