The letter of acceptance (LoA) is not a rating letter. It cannot be used as a substitute for a valid rating letter or for risk weightage purposes.
The only process to ascertain the validity of a rating letter is explained in the answer to question no 3.
Crisil Ratings shares an LoA along with draft rating rationale with the client before ratings are accepted and made public for the first time. Only after the client accepts the rating by signing the LoA, the rating rationale is published on the Crisil Ratings’ website, The rating is kept under surveillance, and thus forms part of our ratings transition matrix. Until this process is completed, the rating is not in the public domain and cannot be used by banks for risk weightage purposes. As per Section 6.2.5 of RBI’s NCAF, ratings that are made available only to the parties to a transaction do not satisfy the requirement.
If the client chooses not to accept the rating assigned by Crisil Ratings, even though the unaccepted rating is disclosed on our website as per regulatory requirements, such a rating is not kept under surveillance. Consequently, the ratings do not form part of our transition matrix and are ineligible for use by banks as outlined in Section 6.2.5 of the RBI’s NCAF, which states that a rating must be published in an accessible form and included in the external credit agency’s transition matrix.
