(25)Credit rating agencies should disclose information to the public on the methodologies, models and key rating assumptions which they use in their credit rating activities. The level of detail concerning the disclosure of information concerning models should be such as to give adequate information to the users of credit ratings in order to perform their own due diligence when assessing whether to rely or not on those credit ratings. Disclosure of information concerning models should not, however, reveal sensitive business information or seriously impede innovation.
