Corporate Governance Reform and Transparency Act of 2019 This bill requires a proxy advisory firm to register with the Securities and Exchange Commission (SEC) and prohibits an unregistered proxy advisory firm from using interstate commerce to provide proxy-voting research, analysis, or recommendations to any client. With respect to these firms, the bill (1) establishes procedures for both registration and termination of registration; (2) requires each firm to employ an ombudsman, designate a compliance officer, and file specified documents with the SEC; and (3) prohibits unfair, coercive, or abusive practices. The SEC must report annually on its website regarding registration applications and related matters.
