The Board of each of TYG, NTG and TTP has designated Mr. Birzer and Ms. Paquette as the directors the preferred stockholders of that Company shall have the right to elect.

Holders of preferred shares of each of TYG, NTG and TTP will vote as a class on the election of Mr. Birzer as a director of each Company, and holders of common shares and preferred shares of each of TYG, NTG and TTP will vote as a single class on the election of Ms. HergerMr. Ciccotello as a director of each Company.

each Board member. Unless otherwise indicated, the address of each director is 6363 College Boulevard, Suite 100A, Overland Park, Kansas 66211. The Investment Company Act of 1940, Actas amended (the “1940 Act”) requires the

8

term “Fund Complex” to be defined to include registered investment companies advised by the Company’s investment adviser, Tortoise Capital Advisors, L.L.C. (the “Adviser”). As of May 31, 2022,2023, for each Director, the Fund Complex included TYG, TPZ, NTG, TTP, NDP, TEAF and for Mr. Ciccotello, the Fund Complex also includes Ecofin Tax-Advantaged Social ImpactTax-Exempt Private Credit Fund, Inc. (“TSIFX”) whose investment adviser is the Adviser and on whose board Mr. Ciccotello serves. The Adviser also serves as the investment adviser to fivefour open end mutual funds.

6

In addition to the experience provided in the table above, each director possesses the following qualifications, attributes and skills, each of which factored into the conclusion to invite them to join the Company’s Board of Directors: Mr. Ciccotello, experience as a college professor, a Ph.D. in finance and expertise in energy infrastructure MLPs; Mr. Berney, experience as a college professor,

7

executive leadership and business experience; Ms. Herger, executive leadership and business experience; Ms. Paquette, investment management experience as a chief investment officer of a state public employees’ retirement association; and Mr. Birzer, investment management experience as an executive, portfolio manager and leadership roles with the Adviser.

Other attributes and qualifications considered for each director in connection with their selection to join the Board of Directors of each Company were their character and integrity and their willingness and ability to serve and commit

12

the time necessary to perform the duties of a director for all of the Companies. In addition, as to each director other than Mr. Birzer, his or her status as an Independent Director; and, as to Mr. Birzer, his roles with the Adviser were an important factor in his selection as a director. No experience, qualification, attribute or skill was by itself controlling.

Mr. Birzer serves as Chairman of the Board of Directors of each Company. Mr. Birzer is an “interested person” of the Companies within the meaning of the 1940 Act. The appointment of Mr. Birzer as Chairman reflects each Board of Directors’ belief that his experience, familiarity with each Company’s day-to-day operations and access to individuals with responsibility for each Company’s management and operations provides the Board of Directors with insight into each Company’s business and activities and, with his access to appropriate administrative support, facilitates the efficient development of meeting agendas that address each Company’s business, legal and other needs and the orderly conduct of meetings of the Board of Directors. Mr. Ciccotello serves as Lead Independent Director. The Lead Independent Director will, among other things, chair executive sessions of the four directors who are Independent Directors, serve as a spokesperson for the Independent Directors and serve as a liaison between the Independent Directors and each Company’s management. The Independent Directors will regularly meet outside the presence of management and are advised by independent legal counsel. The Board of Directors also has determined that its leadership structure, as described above, is appropriate in light of each Company’s size and complexity, the number of Independent Directors and the Board of Directors’ general oversight responsibility. The Board of Directors also believes that its leadership structure not only facilitates the orderly and efficient flow of information to the Independent Directors from management, but also enhances the independent and orderly exercise of its responsibilities.

Information About Executive Officers

Mr. Birzer is the Chairman of the Board of each Company. The preceding tables give more information about Mr. Birzer. The following table sets forth each other executive officer’s name, age and address; position(s) held with the Company and length of time served; principal occupation during the past five years; the number of portfolios in the Fund Complex overseen by each officer and other public company directorships held by each officer. Unless otherwise

8

indicated, the address of each officer is 6363 College Boulevard, Suite 100A, Overland Park, Kansas 66211. Each officer serves until his or her successor is

13

elected and qualified or until his or her resignation or removal. As employees of the Adviser, each of the following officers are “interested persons” of the Company, as that term is defined in Section 2(a)(19) of the 1940 Act.

Committees of the Board of Directors of each Company

Each Company’s Board of Directors currently has four standing committees: (i) the Executive Committee; (ii) the Audit and Valuation Committee; (iii) the Nominating and Governance Committee; and (iv) the Compliance Committee. Currently, all of the non-interested directors, Messrs. Ciccotello and Berney and Mses. Herger and Paquette, are the only members of each of these committees, except for the Executive Committee, for each Company. Each Company’s Executive Committee currently consists of Mr. Birzer and Mr. Ciccotello.

Executive Committee. The Executive Committee of each Company has authority to exercise the powers of the Board (i) to address emergency matters where assembling the full Board in a timely manner is impracticable, or (ii) to address matters of an administrative or ministerial nature. Mr. Birzer is an

12

“interested “interested person” of each Company as defined by Section 2(a)(19) of the 1940 Act. In the absence of either member of the Executive Committee, the remaining member is authorized to act alone.

18

compensation, retention or termination and oversight of the independent registered public accounting firm (“auditors”); (ii) approves services to be rendered by the auditors and monitors the auditors’ performance; (iii) reviews the results of each Company’s audit; (iv) determines whether to recommend to the Board that the Company’s audited financial statements be included in the Company’s Annual Report; and (v) responds to other matters as outlined in the Committee Charter. Each Committee member is “independent” as defined under the applicable New York Stock Exchange listing standards, and none are “interested persons” of the Company as defined in the 1940 Act. The Board of Directors of each company has determined that Conrad S. Ciccotello and Rand C. Berney are each an “audit committee financial expert.” In addition to his experience overseeing or assessing the performance of companies or public accountants with respect to the preparation, auditing or evaluation of financial statements, Mr. Ciccotello has a Ph.D. in Finance.

1319

terminate any search firm used to identify director candidates and to approve the search firm’s fees and other retention terms, though it has yet to exercise such authority; and (v) may not delegate its authority. The Nominating and Governance Committee will consider stockholder recommendations for nominees for membership to the Board so long as such recommendations are made in accordance with the Company’s Bylaws. Nominees recommended by stockholders in compliance with the Bylaws of the Company will be evaluated on the same basis as other nominees considered by the Committee. Stockholders should see “Stockholder Proposals and Nominations for the 2023 Annual Meeting” below for information relating to the submission by stockholders of nominees and matters for consideration at a meeting of the Company’s stockholders. The Bylaws of each Company (not including TEAF) require all nominees for directors, at the time of nomination, (1) to be at least 21 and less than 75 years of age and have substantial expertise, experience or relationships relevant to the business of the Company, or (2) to be a current director of the Company that has not reached 75 years of age. The Committee has the sole discretion to determine if an individual satisfies the foregoing qualifications. The Committee also considers the broad background of each individual nominee for director, including how such individual would impact the diversity of the Board, but does not have a formal policy regarding consideration of diversity in identifying nominees for director.

The Board of Directors’ role in the Company’s risk oversight reflects its responsibility under applicable state law to oversee generally, rather than to manage, the Company’s operations. In line with this oversight responsibility, the Board of Directors will receive reports and make inquiry at its regular meetings and as needed regarding the nature and extent of significant risks (including investment, compliance and valuation risks) that potentially could have a materially adverse impact on the Company’s business operations, investment performance or reputation, but relies upon the Company’s management to assist it in identifying and understanding the nature and extent of such risks and determining whether, and to what extent, such risks may be eliminated or mitigated. In addition to reports and other information received from the

14

Company’s management regarding its investment program and activities, the Board of Directors as part of its risk oversight efforts will meet at its regular meetings and as needed with the Adviser’s Chief Compliance Officer to discuss, among other things, risk issues and issues regarding the Company’s policies, procedures and controls. The Board of Directors may be assisted in performing aspects of its role in risk oversight by the Audit and Valuation Committee and such other standing or special committees as may be established from time to time. For example, the Audit and Valuation Committee will regularly meet with the Company’s independent public accounting firm to review, among other things, reports on internal controls for financial reporting.

20

The Board of Directors believes that not all risks that may affect the Company can be identified, that it may not be practical or cost-effective to eliminate or mitigate certain risks, that it may be necessary to bear certain risks (such as investment-related risks) to achieve the Company’s goals and objectives, and that the processes, procedures and controls employed to address certain risks may be limited in their effectiveness. Moreover, reports received by the directors as to risk management matters are typically summaries of relevant information and may be inaccurate or incomplete. As a result of the foregoing and other factors, the risk management oversight of the Board of Directors is subject to substantial limitations.

None of the Companies currently has a standing compensation committee. None of the Companies has any employees and the New York Stock Exchange does not require boards of directors of registered closed-end funds to have a standing compensation committee.

The following table shows the number of Board and committee meetings held during the fiscal year ended November 30, 20212022 for each of the Companies:

During the 20212022 fiscal year, for each of the Companies, all directors who were directors during the 20212022 fiscal year attended at least 75% of the aggregate of (1) the total number of meetings of the Board and (2) the total number of meetings held by all committees of the Board on which they served. None of the Companies has a policy with respect to Board member attendance at annual meetings. All of the directors of each of TYG, TPZ, NTG, TTP, NDP and TEAF attended the Company’s 20212022 annual meeting virtually.

ADDITIONAL INFORMATION

On May 12, 2023, plaintiffs Howard Nathanson and Gus Gordon, derivatively and on behalf of TYG and NTG, filed a suit against H. Kevin Birzer, Conrad S. Ciccotello, Rand C. Berney, Jennifer Paquette, and Alexandra Herger, and against the Adviser, in the Circuit Court for Baltimore City, Maryland. TYG and NTG also were named in the suit as Nominal Defendants. The complaint, among other things, alleges derivative claims for breach of fiduciary duty related to the Adviser’s management of TYG and NTG and the Director Defendants’ oversight thereof and

1521

for the adoption of amendments to the Bylaws of TYG and NTG in October 2020 which the complaint alleges were illegal under the 1940 Act. The complaint seeks unspecified damages related to the alleged breaches of fiduciary duty, rescission of the Adviser’s investment advisory contract for TYG and NTG pursuant to an alleged violation of the Investment Advisers Act of 1940, and, on behalf of the plaintiffs in their individual capacities as shareholders of TYG and NTG, recission of the allegedly illegal Bylaws provisions pursuant to the 1940 Act. The case is Howard Nathanson and Gus Gordon, derivatively on behalf of Tortoise Energy Infrastructure Corp. and Midstream Energy Fund v. Tortoise Capital Advisors, L.L.C. et al., Baltimore City Circuit Court, Maryland. Plaintiffs had filed a similar action in the U.S. District Court for the District of Kansas in August 2022, which was dismissed without prejudice as a result of the forum selection clause in the Bylaws of TYG and NTG. While management of the Adviser and the Director Defendants are unable to predict the outcome of this matter, they believe that this case is without merit and intend to defend against it vigorously, and do not believe the outcome would result in the payment of any monetary damages by TYG or NTG.

Director and Officer Compensation

None of the Companies compensates any of its directors who are interested persons nor any of its officers. The following table sets forth certain information with respect to the compensation paid by each Company and the Fund Complex for fiscal 20212022 to each of the current independent directors for their services as a director.

The Board of Directors of each Company unanimously recommends that stockholders of each Company vote “for” the ratification of Ernst & Young LLP as their Company’s Independent Registered Public Accounting Firm.

PROPOSAL 3 FOR TPZ ONLY: A SHAREHOLDER PROPOSAL

A shareholder (referred to in this proposal as the “Shareholder Proponent”) has informed TPZ (or the “Fund” for purposes of this Shareholder Proposal) that it intends to submit the Shareholder Proposal at the Meeting and has requested that TPZ include the Shareholder Proposal in TPZ’s proxy materials. The non-binding Shareholder Proposal, exactly as received by TPZ, is set forth below, followed by the Board’s explanation of its reasons for opposing the Shareholder Proposal, which in turn is followed by the Shareholder Proponent’s supporting statement for the Shareholder Proposal (the “Supporting Statement”), exactly as received by TPZ. The Board unanimously recommends that you vote AGAINST the non-binding Shareholder Proposal.

Proposal:

RESOLVED: The shareholders of Tortoise Power and Energy Infrastructure Fund, Inc. (the Fund) request that the Board of Directors authorize a self-tender offer for all outstanding common shares of the Fund at or close to net asset value (NAV). If more than 50% of the Fund’s outstanding common shares are submitted for tender, the Board is requested to cancel the tender offer and take those steps that the Board is required to take to cause the Fund to be liquidated or converted to (or merged with) an exchange traded fund (ETF) or an open-end mutual fund.

OPPOSITION STATEMENT OF TPZ

TPZ’s Board of Directors has weighed the advantages and disadvantages of the Shareholder Proposal based on what it believes is in the best interests of TPZ’s shareholders. The Board opposes the Shareholder Proposal because it would deny shareholders the ability to own shares in a successful investment vehicle with long-term investment objectives, waste Fund resources, and potentially result in TPZ’s termination. Instead, the Board believes that TPZ should retain its current structure as a closed-end fund, which provides significant benefits to long-term shareholders:

1924

In addition to these benefits, in January 2022, the Board announced a conditional tender offer for up to 5% of TPZ’s outstanding shares for each of the calendar years 2022 and 2023. TPZ would conduct a tender for 5% of the Fund’s outstanding shares of common stock at a price equal to 98% of NAV if its shares trade at an average discount to NAV of more than 10% during either of the designated measurement periods. The first measurement period commenced on February 1, 2022 and will end July 31, 2022 for 2022, and the second measurement period will commence on August 1, 2022 and end July 31, 2023, for 2023. These tenders would potentially allow TPZ shareholders with an opportunity for liquidity at an above-market price while still nonetheless maintaining a fund of sufficient size to achieve its investment objectives and take advantage of leverage.

FOR THE REASONS DISCUSSED MORE FULLY BELOW,
THE BOARD UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS
VOTE AGAINST THE SHAREHOLDER PROPOSAL.

Discount to NAV. The Shareholder Proposal criticizes the discount between TPZ’s market share price and its NAV per share. Closed-end funds typically trade at a discount to net asset value. However, the Board has already taken meaningful and effective action to reduce TPZ’s discount, including: (1) adopting a managed distribution policy to make regular distributions to TPZ shareholders; (2) adopting a share repurchase program in 2020; and (3) early in 2022, enhancing TPZ’s managed distribution policy to make monthly distributions currently targeted at an annual rate of 7 to 10% of NAV. As a result of this most recent Board action, Fund shareholders are receiving significant distributions from TPZ every month. The distribution as of January 18, 2022 was $0.105 per share per month ($0.315 per quarter) an increase of 75% from the monthly distribution for the prior quarter. Further, the discount to NAV has dropped 18.7% as of May 2021 to 9.6% at May 11, 2022.

On January 18, 2022, the Board announced a conditional limited tender offer for up to 5% of TPZ’s outstanding shares at 98% of NAV per share. The Board believes this more limited tender offer, assuming the average discount to NAV exceeds 10% for the requisite measurement period, reasonably balances the interests of shareholders seeking an opportunity for liquidity in their fund shares at an above-market price with the interests of shareholders who desire to remain invested in a fund that has delivered meaningful returns over the past decade, and continues to distribute a high monthly distribution to shareholders.

Given TPZ’s improved discount and increased distribution rate, the Board believes that it would be unwise to recommend the drastic step of the Shareholder Proposal’s unlimited tender offer, possibly followed by open-ending or liquidating TPZ, any of which would seriously impair or eliminate TPZ as a viable investment option for the many shareholders that have purposefully chosen to invest in this closed-end fund.

20

Significant Costs of the Shareholder Proposal. As part of its evaluation, the Board also considered the significant costs TPZ would bear if the Shareholder Proposal were implemented. The Shareholder Proposal requests that the Board take two distinct actions: first, commence an unlimited tender offer for all of TPZ’s shares at (or near) NAV per share; and second, if at the conclusion of the Shareholder Proposal’s unlimited tender offer, more than half of TPZ’s shares have been tendered, cancel the just-completed tender offer (after the transaction expenses of the tender have been incurred), and either liquidate TPZ or convert it to an open-end (mutual) fund, and incur the costs of open-ending or liquidating. These actions would waste fund assets and significantly diminish TPZ’s ability to operate efficiently, potentially even resulting in TPZ’s termination, without providing any meaningful benefits to TPZ’s long-term shareholders. The Board’s more limited tender offer, by contrast, provides shareholders with an opportunity for liquidity at an above-market price while nonetheless maintaining a Fund of sufficient size to achieve its investment objectives and take advantage of leverage.

An unlimited tender offer would be costly to shareholders and could adversely affect Fund performance. If the Shareholder Proposal’s unlimited tender offer were completed, TPZ would need to liquidate a material amount of portfolio securities to accumulate sufficient cash to pay for the tendered shares. Liquidating these securities would likely force TPZ to sell its portfolio securities at an inopportune time, would increase portfolio transaction costs, would generate adverse capital gains tax consequences for shareholders, would cause TPZ to bear additional expenses in rebalancing its portfolio following such sales, and in general would significantly diminish TPZ’s ability to operate efficiently. Remaining Fund shareholders would likely suffer from a substantially reduced asset base, a higher expense ratio, lower dividends, and the costs of the Shareholder Proposal’s unlimited tender offer. The Board and Fund management believe that it would be much more difficult for TPZ to meet its investment objectives and maintain its current distribution rate after being so severely diminished in size.

Open-ending TPZ would require holding an additional shareholder meeting to obtain approval, which would take additional time and expense without any guarantee that shareholder approval would be obtained. TPZ would also incur potentially significant administrative, trading, and legal costs in transitioning to an open-end fund. As an open-end fund, TPZ could not use leverage to the same degree as a closed-end fund with the likely result a decrease in TPZ’s distributable cash flow, and redemptions could result in a significant decrease in assets and increased volatility. Liquidating TPZ would completely eliminate TPZ as a long-term investment option.

TPZ’s proposed more limited tender offer, by contrast, significantly reduces or avoids the problems that would arise under the Shareholder Proposal. The Board’s tender offer balances a reasonable liquidity opportunity for shareholders at an above-market price with preserving TPZ as an investment choice for longer-term

21

and income-oriented investors that purposefully chose to invest in this closed-end fund. Purchasing shares at 98% of NAV per share will enable remaining shareholders to defray the costs of the tender offer, including the trading costs associated with raising cash to repurchase tendered shares. Moreover, a more limited tender offer will likely be more tax efficient because TPZ’s portfolio managers will be better able to selectively dispose of portfolio securities, resulting in lower capital gains to TPZ’s remaining shareholders than would be the case under the Shareholder Proposal. The Board’s approach will leave sufficient assets for TPZ to continue to pursue its investment objectives, to continue to use leverage, and will allow TPZ to maintain its regular and significant distributions.

The Board therefore believes that the significant and effective measures it has already taken are a much more responsible approach to addressing TPZ’s discount than the Shareholder Proposal.

Conclusion. The Board unanimously opposes the Shareholder Proposal because it invites TPZ’s termination as a closed-end fund. TPZ continues to maintain adequate trading volume, an improved discount, and viable size. The Board, through its managed distribution policy, has already provided a much more effective means of addressing the discount, one which will not end up dismantling TPZ. Similarly, the Board’s more limited tender offer in the event that TPZ’s discount exceeds 10% during an annual measurement period will provide shareholders with an opportunity for liquidity at an above-market price while nonetheless maintaining a Fund of sufficient size to achieve its investment objectives and take advantage of leverage. The Board therefore believes that the significant measures it has already taken together with the limited tender offer justify retaining TPZ’s closed-end structure for the benefit of all shareholders. By contrast, the Board believes that the Shareholder Proposal’s unlimited tender offer, possibly followed by open-ending or liquidating TPZ, would deprive TPZ’s long-term shareholders of the characteristics they were seeking when they originally chose to invest in this closed-end fund.

The Board believes it has taken thoughtful and measured actions to achieve an appropriate balance between satisfying shareholders’ interests in liquidity with their interests in current income and capital appreciation.

FOR THE REASONS STATED ABOVE, THE BOARD UNANIMOUSLY
RECOMMENDS THAT SHAREHOLDERS VOTE AGAINST
THE NON-BINDING SHAREHOLDER PROPOSAL.

22

SUPPORTING STATEMENT OF THE SHAREHOLDER PROPONENT

The Shareholder Proponent’s Supporting Statement is as follows:

Since its IPO on July 28, 2009 through November 30, 2021, the Fund returned 4.88% per year based upon NAV but only 3.94% per year based upon market price. Thus, the discount has cost shareholders almost 1% per year over that time span. Over the past three years, the discount has averaged about 15%. In August 2021, the Board made a modest attempt to narrow the discount by adopting a managed distribution policy but shareholders seeking to sell shares still can only do so at a hefty discount from NAV.

In addition, the Board of Directors has adopted certain arguably illegal anti-takeover measures to insulate itself from shareholders that are unhappy about the Fund’s persistently wide discount.

Consequently, we think it is appropriate for the Board to authorize a self-tender offer for the Fund’s shares at or close to NAV to afford shareholders an opportunity to sell their shares at a price that is greater than the market price. If a majority of the Fund’s outstanding common shares are tendered, that would demonstrate that there is insufficient shareholder support for continuing the Fund in its closed-end format. In that case, we think the tender offer should be cancelled and the Fund should be liquidated or converted into (or merged with) an ETF or an open-end mutual fund.

If you agree that it is time to implement more effective measures to address the Fund’s persistent discount, please vote for this (non-binding) proposal.

The Shareholder Proponent is Special Opportunities Fund, Inc., 615 East Michigan Street, Milwaukee, WI 53202. Neither TPZ, its Board nor management is responsible for the contents of the Shareholder Proposal or the Supporting Statement of the Shareholder Proponent.

Required Vote

To be approved, the Shareholder Proposal must be approved by the affirmative vote of a majority of the outstanding TPZ common shares cast at the Meeting, which means a vote of the lesser of (1) a majority of the outstanding shares of TPZ, or (2) 67% or more of the shares of TPZ represented at the Meeting if more than 50% of the outstanding shares of TPZ are present or represented by proxy. Each TPZ common share is entitled to one vote on this proposal. For purposes of the vote on this proposal, abstentions and broker non-votes, if any, will have the same effect as votes against the proposal, since approval is based on the affirmative vote of all votes entitled to be cast.

BOARD RECOMMENDATION

The Board of Directors of TPZ unanimously recommends that shareholders vote “against” the Shareholder Proposal.

AUDIT AND VALUATION COMMITTEE REPORT

The Audit and Valuation Committee of each of TYG, TPZ, NTG, TTP, NDP and TEAF, reviews the Company’s annual financial statements with both management and the independent auditors.

The Audit and Valuation Committee of each Company, in discharging its duties, has met with and has held discussions with management and the Company’s independent auditors. Each Company’s Audit and Valuation Committee has reviewed and discussed the Company’s audited financial statements for the fiscal year ended November 30, 20212022 with management. Management of each Company has represented to the independent auditors that the Company’s financial statements were prepared in accordance with U.S. generally accepted accounting principles.

The Audit and Valuation Committee of each Company has also discussed with the independent auditors the matters required to be discussed by Auditing Standard 1301, Communications with Audit Committees, as adopted by the Public Company Accounting Oversight Board. The independent auditors provided to each Company’s Audit and Valuation Committee the written disclosures and the letter required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent auditors’ communications with the Audit and Valuation Committee concerning independence, and each Company’s Audit and Valuation Committee discussed with representatives of the independent auditors their firm’s independence with respect to that Company.

With respect to each Company, based on the Audit and Valuation Committee’s review and discussions with management and the independent auditors, the representations of management and the reports of the independent auditors to the committee, the Audit and Valuation Committee recommended that the Board include the audited financial statements in the Company’s Annual Report for filing with the SEC.

The Audit and Valuation Committee of each of

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Each Company’s Audit and Valuation Committee selected EY as the independent registered public accounting firm to audit the books and records of the Company for its fiscal year ending November 30, 2021.2023. EY is registered with the Public Company Accounting Oversight Board.

2425

FEES AND SERVICES

The following table sets forth the approximate amounts of the aggregate fees billed to each Company for the fiscal years ended November 30, 20212022 and 20202021 by EY, respectively:

The Audit and Valuation Committee of each Company has adopted pre-approval policies and procedures. Under these policies and procedures, the Audit and Valuation Committee of each Company pre-approves (i) the selection of the Company’s independent registered public accounting firm, (ii) the engagement of the independent registered public accounting firm to provide any non-audit services to the Company, (iii) the engagement of the independent registered public accounting firm to provide any non-audit services to the Adviser or any entity controlling, controlled by, or under common control with the Adviser that provides ongoing services to the Company, if the engagement relates directly to the operations and financial reporting of the Company, and (iv) the fees and other compensation to be paid to the independent registered public accounting firm. With respect to each Company, the Chairman of the Audit and Valuation Committee of the Company may grant the pre-approval of any engagement of the independent registered public accounting firm for non-audit services of less than $10,000, and such delegated pre-approvals will be presented to the

2526

full Audit and Valuation Committee at its next meeting for ratification. Under certain limited circumstances, pre-approvals are not required under securities law regulations for certain non-audit services below certain de minimus thresholds. Since each Company’s respective adoption of these policies and procedures, the Audit and Valuation Committee of the Company has pre-approved all audit and non-audit services provided to the Company by EY. None of these services provided by EY were approved by the Audit and Valuation Committee pursuant to the de minimus exception under Rule 2.01(c)(7)(i)(C) or Rule 2.01(c)(7)(ii) of Regulation S-X. All of EY’s hours spent on auditing each Company’s financial statements were attributed to work performed by full-time permanent employees of EY.

The Adviser paid to EY $39,750 in 2020 and $31,400 in 2021 and $29,850 in 2022 for tax and other non-audit services provided to the Adviser. These non-audit services were not required to be preapproved by each Company’s Audit and Valuation Committee. No entity controlling, controlled by, or under common control with the Adviser that provides ongoing services to any of the Companies, has paid to, or been billed for fees by, EY for non-audit services rendered to the Adviser or such entity during the Companies’ last two fiscal years.

The Audit and Valuation Committee of each Company has considered whether EY’s provision of services (other than audit services) to the Company, the Adviser or any entity controlling, controlled by, or under common control with the Adviser that provides services to the Company is compatible with maintaining EY’s independence in performing audit services.
