(18)With the aim of strengthening competition and limiting the scope for conflicts of interest in the CRA sector, Regulation (EU) No 462/2013 introduces a requirement in Annex I, Section E, Subsection II of Regulation (EC) No 1060/2009 that fees charged by CRAs for credit ratings and ancillary services should be non-discriminatory and based on actual costs. It requires CRAs disclose certain financial information. The Mexican legal and supervisory framework requires a CRA to provide to the CNBV data on fees charged to individual clients pointing out the revenue from each of them and detailing all services provided to each one during immediately preceding year. CRAs shall disclose publicly whether they have received from the same rated entity fees relating to services different from rating services and the percentage in connection with the rating services fees. Furthermore, there is a general requirement for CNBV to guarantee fair treatment of all clients of CRAs.
