Credit rating regulation alignment with Companies Act enhances definitional consistency and limits investigatory scope to listed securities. Amendments align regulatory definitions and cross references for credit rating agencies with the Companies Act, 2013, replace references to public or rights issues by focusing on securities that are listed or proposed to be listed on a recognized stock exchange, and provide that undefined terms shall have meanings assigned in the Act, the Securities Contracts (Regulation) Act, the Companies Act, 2013, or related rules. An explanation confirms ratings under financial sector regulators remain within those regulators' purview and SEBI's investigatory remit is limited to ratings of listed or proposed listed securities.
