Dear Ms. Vroman-Lee:

On behalf of the Funds, set forth below are the Funds’ responses to the comments provided by the staff (the “Staff”) of the Division of Investment Management of the Securities and Exchange Commission (“SEC”) by telephone on January 7, 2022, regarding the Funds’ joint preliminary proxy statement filed with the SEC on December 30, 2021 (the “Preliminary Proxy Statement”). All capitalized terms not defined in this letter have the meanings set out in the Preliminary Proxy Statement.

The Staff’s comments are set forth in italics followed by the Funds’ response.

1. Page 1 of the joint proxy statement indicates that “[t]he Funds will bear the cost of the annual proxy meeting and this proxy solicitation.” Please include disclosure regarding how much this is expected to be, as the cost may be material to Fund shareholders.

Response: The Funds have revised the disclosure to provide the estimated costs of the annual meeting and proxy solicitation, including the printing and mailing of proxy materials.

2. Page 14 of the joint proxy statement, under the heading “Potential Risks of the Proposed Amendment,” includes disclosure that “[o]ther than in connection with its existing Reinvestment Plan and ATM offering program, DNP has no present intention to issue any additional shares of common stock.” Please consider including disclosure that although there is no current intent to do so, there is no guarantee or assurance that the additional shares authorized for issuance will be used solely for the Reinvestment Plan and ATM offering program.
