It is our policy to exercise the voting rights of the accounts we manage in the best interests of the portfolios and with a view to enhancing the long-term value of the securities held. Voting responsibly is part of our fiduciary duty and we make our voting decisions independently, in accordance with our custom voting guidelines. Through the exercise of our voting rights, we encourage issuers and their boards of directors to consider and adopt recognized best practices in governance and disclosure.
Through our internal expertise and resources, as well as research provided by independent research firms, we have established our own custom proxy voting guidelines. These guidelines are published for the information of clients and to assist issuers in understanding the message we have sent or intend to send through the exercise of proxy voting rights. We review and update the guidelines on an annual basis as corporate governance best practices evolve.
We believe that shareholders should have the right to have relevant proposals included on the proxy ballot as long as they deal with appropriate issues. We are prepared to file shareholder resolutions in certain circumstances including where ESG risks are not adequately disclosed.
