Although each Fund is holding a separate meeting, the meetings will be held concurrently. Shareholders of each Fund will vote separately. Any such vote FOR or AGAINST the proposal will also authorize the persons named as proxies to vote accordingly FOR or AGAINST any such adjournment of the Annual Meeting of Shareholders.

The Board of Trustees of each Fund has fixed the close of business on February 2, 2021 as the record date for the determination of the shareholders of a Fund entitled to notice of and to vote at the meeting and any adjournments or postponements thereof. As part of our effort to maintain a safe and healthy environment at our Annual Meeting, the Fund and the Board are closely monitoring developments with respect to the novel coronavirus, COVID-19, and the advice and guidance of public health officials. For that reason, the Board reserves the right to reconsider the date, time and/or means of convening the Annual Meeting. Subject to any restrictions imposed by applicable law, the Board may choose to conduct the meeting solely by means of remote communications, or may hold a "hybrid" meeting where some participants attend in person and others attend by means of remote communications. If the Board chooses to change the date, time and/or means of convening the Annual Meeting, the Fund will announce the decision to do so in advance, and details on how to participate will be issued by press release and filed with the Securities and Exchange Commission as additional proxy material. Attendees are also encouraged to review guidance from public health authorities on this issue.

By Order of each Board of Trustees
