(11)Regulation (EU) No 462/2013 introduces safeguards in Article 8(5a)(6) aa and ab and (7) of Regulation (EC) No 1060/2009 to ensure that any modification to rating methodologies does not result in less rigorous methodologies. Although the Brazilian legal and supervisory framework states that a CRA should disclose to the regulator and the market any material change to its methodologies, it does not have requirements for CRAs to consult on changes to methodologies or to correct any errors in their methodologies. While there is a requirement to communicate the scope of rated entities affected by a change to a methodology, there is no requirement to explain the reason thereof or to notify the supervisor.
