The Funds have filed a definitive proxy statement on Schedule 14A with the Securities and Exchange Commission (SEC) in connection with the special meetings of shareholders to approve new investment advisory agreements and elect seven trustees. Information regarding the persons who may, under SEC rules, be deemed participants in the solicitation of the Funds’ shareholders to approve the new investment advisory agreements and elect trustees, including, without limitation, the Funds and Parnassus Investments, and a description of the participants’ direct or indirect interests, by security holdings or otherwise, is set forth in the definitive proxy statement. Shareholders may obtain a free copy of the definitive proxy statement and proxy cards and other documents filed by the participants with the SEC at the SEC’s web site at www.sec.gov. The definitive proxy statement and other related SEC documents filed by the participants with the SEC may also be obtained free of charge from the Funds by calling (888) 541-9895. Shareholders are urged to read the definitive proxy statement and proxy cards, because they contain important information about the Funds, the participants, the new investment advisory agreements, the nominees, and related matters.
