Proxy advisory firms, notably Institutional Shareholder Services (ISS) and Glass Lewis, play a significant role in guiding institutional investors on corporate governance matters. Collectively, these two firms control approximately 97% of the proxy advisory market, granting them substantial influence over shareholder voting outcomes.

Critics argue that this concentration of power lacks sufficient transparency and accountability. Concerns have been raised about potential conflicts of interest, as these firms may provide consulting services to the same companies they evaluate, potentially compromising the objectivity of their recommendations.

In response to these concerns, legislative efforts have been initiated to enhance oversight of proxy advisory firms. The Corporate Governance Fairness Act, a bipartisan bill, proposes requiring proxy advisory firms to register with the Securities and Exchange Commission (SEC) under the Investment Advisers Act of 1940. This legislation aims to increase transparency by mandating disclosure of conflicts of interest and ensuring that proxy advisors’ methodologies are subject to regulatory scrutiny.

The SEC has also taken steps to address these issues. In July 2020, the Commission adopted amendments to the proxy rules governing proxy advisors. These amendments require proxy advisory firms to disclose material conflicts of interest and provide companies with an opportunity to review and respond to their recommendations before they are disseminated to clients. The SEC’s objective is to enhance the accuracy and transparency of proxy voting advice, thereby promoting informed decision-making among shareholders.

Opponents contend that such regulations may impede the independence of proxy advisors and limit their ability to provide candid assessments of corporate governance practices.
