PROXY STATEMENT

Important Notice Regarding the Availability of Proxy Materials for the Annual Meeting of Stockholders to be Held on May 19, 2023:

The proxy statement and related materials are available at:

https://www.proxy-direct.com/fnk-33231

This proxy statement is furnished in connection with the solicitation by the Board of Directors (the “Board”) of Western Asset Investment Grade Income Fund Inc. (the “Fund”) of proxies to be voted at the Annual Meeting of Stockholders of the Fund (the “Annual Meeting”) to be held at 280 Park Avenue, 7th Floor, New York, New York, on Friday, May 19, 2023, at 10:00 a.m., Eastern Time, and at any adjournment(s) or postponement(s) thereof. At the Annual Meeting, stockholders will be asked to consider the re-election of eleven Directors (collectively, the “Nominees”) to the Board.

If it is determined that the Annual Meeting will be held at a different time or in a different location or format (i.e., a virtual or hybrid meeting), an announcement of any such updates will be provided by means of a press release, which will be posted on our website (www.franklintempleton.com/investments/options/closed-end-funds). We encourage you to check the website prior to the Annual Meeting if you plan to attend the Annual Meeting. An announcement of any change will also be filed with the Securities and Exchange Commission (the “SEC”) via its EDGAR system.

This Proxy Statement and the accompanying form of proxy are first being sent or given to stockholders on or about April 11, 2023. Please note that only one annual or semi-annual report or Proxy Statement may be delivered to two or more stockholders of the Fund who share an address, unless the Fund has received instructions to the contrary. To request a separate copy of an annual or semi-annual report or the Proxy Statement, or for instructions as to how to request a separate copy of these documents or as to how to request a single copy if multiple copies of these documents are received, stockholders should contact the Fund at 620 Eighth Avenue, 47^th Floor, New York, New York 10018 or by calling toll free at 1-888-777-0102.

The Board has fixed the close of business on March 30, 2023 as the record date (the “Record Date”) for the determination of stockholders of the Fund entitled to notice of and to vote at the Annual Meeting. As of the close of business on the Record Date, there were 9,510,962 shares of the Fund’s common stock (the “Common Stock”) outstanding and entitled to one vote per share (and a fractional vote with respect to fractional shares) with respect to each matter to be voted on at the Annual Meeting. The outstanding shares of Common Stock constitute the only outstanding voting securities of the Fund entitled to be voted at the Annual Meeting.

A majority of the outstanding shares of Common Stock as of the close of business on the Record Date must be represented in person or by proxy to constitute a quorum for the Annual Meeting. Directors will be elected by a majority of the votes entitled to be cast in the election of Directors. Except where a different vote is required by any provision of law or the Fund’s Certificate of Incorporation or Amended and Restated Bylaws

-1-

(the “Bylaws”), the affirmative vote of the majority of shares of the Fund’s Common Stock present in person or represented by proxy at the Annual Meeting, at which a quorum is present, and entitled to vote on the subject matter will be the act of the stockholders. In the event of any conflict between a description of the Fund’s Bylaws in the proxy statement and the Fund’s Bylaws, the Fund’s Bylaws will control.

Each stockholder has the right to revoke his or her proxy at any time before it is voted. A proxy, including a proxy given by telephone or via the Internet, may be revoked by filing with the Secretary of the Fund a written revocation or a properly executed proxy bearing a later date (including a proxy given by telephone or via the Internet) or by voting at the Annual Meeting. Any stockholder may attend the Annual Meeting, whether or not he or she has previously given a proxy.

The solicitation of proxies for the Annual Meeting will be made primarily by mail. However, additional solicitation may take place in writing or by telephone by officers of the Fund (or their designees), who will not receive compensation from the Fund for such services. In addition, you may receive a telephone call from our proxy solicitor, Computershare, which has been retained to assist stockholders in the voting process. For these services, the Fund will pay Computershare a fee that is not expected to exceed $15,467. However, the exact cost will depend on the amount and types of services rendered. The Fund will reimburse brokers and other nominees, in accordance with New York Stock Exchange approved reimbursement rates, for their expenses in forwarding solicitation material to the beneficial owners of shares of Common Stock of the Fund. All expenses incurred in connection with the solicitation of proxies by the Board, including the services of Computershare, will be borne by the Fund.

Abstentions and “broker non-votes” (i.e., proxies signed and returned by brokers with respect to shares of Common Stock held by brokers or nominees as to which one or more votes is not indicated because (i) instructions have not been received from the beneficial owners or the persons entitled to vote and (ii) the broker or nominee does not have discretionary voting power on a particular matter) will be counted as shares of Common Stock present for purposes of determining whether a quorum is present. Assuming that a quorum would otherwise be present, abstentions will have the effect of a vote against a Nominee for the purpose of determining whether a Director has been elected.

The Fund expects that broker-dealer firms holding shares of the Fund in “street name” for the benefit of their customers and clients will request the instructions of such customers and clients on how to vote their shares on Proposal 1 before the Annual Meeting. The Fund understands that, under the rules of the New York Stock Exchange, such broker-dealers may, without instructions from such customers and clients, grant authority to the proxies designated by the Fund to vote on Proposal 1 if no instructions have been received prior to the date specified in the broker-dealer firm’s request for voting instructions. Jane E. Trust, Thomas C. Mandia, George P. Hoyt, Tara E. Gormel, Jeanne Kelly and Marc A. De Oliveira, the persons named as proxies on the proxy card accompanying this Proxy Statement, were selected by the Board to serve in such capacity or substituted by the persons selected by the Board. Mses. Trust, Gormel and Kelly and Messrs. Mandia, Hoyt and De Oliveira are officers of the Fund. Each executed and returned proxy will be voted in accordance with the directions indicated thereon or otherwise as provided therein. Discretionary authority is provided in the proxy as to any matters not specifically referred to therein. The Board is not aware of any other matters which are likely to be brought before the Annual Meeting. However, if any such matters properly come before the Annual Meeting, the persons named in the proxy are fully authorized to vote thereon in accordance with their judgment and discretion.

* Indicates the earliest year in which the Director or Nominee became a Board member for a fund in the Fund complex. Each of the Directors of the Fund holds office until his or her successor shall have been duly elected and shall qualify, subject to prior death, resignation, retirement, disqualification or removal from office and applicable law. Any director nominated for re-election as a director who fails to receive the requisite vote for re-election at an annual meeting of stockholders, and whose successor has neither been elected nor qualified, shall holdover and continue to serve as director and shall be nominated for re-election at the next succeeding annual meeting of stockholders until he or she has received the requisite vote or until his successor shall have been elected and shall have qualified, or until his or she death, or until he or she shall have resigned or have been removed as provided by statute or the charter of the Fund.

Additional Information Concerning the Board of Directors. The Board believes that each Nominee’s experience, qualifications, attributes or skills on an individual basis and in combination with those of the other Nominees lead to the conclusion that the Board possesses the requisite skills and attributes. The Board believes that the Nominees’ ability to review, critically evaluate, question and discuss information provided to them, to interact effectively with the Investment Adviser, Western Asset Management Company Limited (the “Subadviser”), other service providers, counsel and independent auditors, and to exercise effective business judgment in the performance of their duties serves to support this conclusion. The Board also has considered the following experience, qualifications, attributes and/or skills, among others, of its members and the Nominees in reaching its conclusion: his or her character and integrity; such person’s length of service as a Board member of the Fund; such person’s willingness to serve and willingness and ability to commit the time necessary to perform the duties of a Director; and as to each Nominee other than Mr. Olson and Ms. Trust, his or her status as not being an “interested person” (as defined in the 1940 Act) of the Fund (such Directors or

-9-

Nominees who are not interested persons of the Fund being referred to as the “Independent Directors”). In addition, the following specific experience, qualifications, attributes and/or skills apply as to each Nominee: Mr. Abeles, business, accounting and finance expertise and experience as a chief financial officer, board member and/or executive officer of various businesses and other organizations; Ms. Dasher, experience as a chief financial officer of a private investment company; Ms. DeFrantz, business expertise and experience as a president, board member and/or executive officer of various businesses and non-profit and other organizations; Ms. Kerley, investment consulting experience and background and mutual fund board experience; Mr. Larson, portfolio management expertise and experience as a board member of various businesses and other organizations; Mr. Poladian, business, finance and accounting expertise and experience as a board member of various businesses and/or as a partner of a multi-national accounting firm; Mr. Siart, business and finance expertise and experience as a president, chairperson, chief executive officer and/or board member of various businesses and non-profit and other organizations; Ms. Studenmund, business and finance expertise and experience as a president, board member and/or chief operating officer of various businesses; Mr. Taylor, business and finance expertise and experience as a chief financial officer, president and/or board member of various businesses and non-profit organizations; Mr. Olson, business and legal expertise and experience as a partner of a law firm and/or board member of various businesses and non-profit and other organizations; and Ms. Trust, investment management and risk oversight experience as an executive and portfolio manager and leadership roles within Franklin Templeton and affiliated entities. References to the qualifications, attributes and skills of the Directors and Nominees are pursuant to requirements of the SEC, do not constitute holding out of the Board or any Nominee as having any special expertise or experience, and shall not impose any greater responsibility or liability on any such person or on the Board by reason thereof.

The Board is responsible for overseeing the management and operations of the Fund. Ms. Trust and Mr. Olson are interested persons of the Fund. Mr. Siart serves as Chairman of the Board. Mr. Siart is an Independent Director. Independent Directors constitute more than 75% of the Board. As described further below, the Board has four standing committees: the Audit Committee, the Executive and Contracts Committee (the “Contracts Committee”), the Governance and Nominating Committee (the “Governance Committee”), and the Investment and Performance Committee (the “Performance Committee”). Each of the Audit, Governance, Contracts and Performance Committees is chaired by an Independent Director and each (other than the Performance Committee) is composed entirely of Independent Directors. Where deemed appropriate, the Board constitutes ad hoc committees.

The Board has determined that its leadership structure is appropriate given the business and nature of the Fund. In connection with its determination, the Board considered that the Chairman of the Board is an Independent Director. The Chairman of the Board can play an important role in setting the agenda of the Board and also serves as a key point person for dealings between management and the other Independent Directors. The Independent Directors believe that the Chairman’s independence facilitates meaningful dialogue between fund management and the Independent Directors. The Board also considered that the chairperson of each Board committee is an Independent Director, which yields similar benefits with respect to the functions and activities of the various Board committees (e.g., each committee’s chairperson works with the Investment Adviser, the Subadviser and other service providers to set agendas for the meetings of the applicable Board committees). As noted above, through the committees the Independent Directors consider and address important matters involving the Fund, including those presenting conflicts or potential conflicts of interest for management. The Independent Directors also regularly meet outside the presence of management and are advised by independent legal counsel. The Board has determined that its committees help ensure that the Fund

-10-

has effective and independent governance and oversight. The Board also believes that its leadership structure, in which the Chair of the Board is not affiliated with Legg Mason or Franklin Templeton, is appropriate. The Board also believes that its leadership structure facilitates the orderly and efficient flow of information to the Independent Directors from management, including the Investment Adviser and Subadviser. The Board reviews its structure on an annual basis.

As an integral part of its responsibility for oversight of the Fund in the interests of stockholders, the Board oversees risk management of the Fund’s investment programs and business affairs. The function of the Board with respect to risk management is one of oversight and not active involvement in, or coordination of, day-to-day risk management activities for the Fund. The Board has emphasized to the Fund’s Investment Adviser and Subadviser the importance of maintaining vigorous risk management. The Board exercises oversight of the risk management process primarily through the Performance Committee, Audit Committee, Contracts Committee and through oversight by the Board itself.

The Fund faces a number of risks, such as investment risk, counterparty risk, valuation risk, reputational risk, risk of operational failure or lack of business continuity, and legal, compliance and regulatory risk. Risk management seeks to identify and address risks, i.e., events or circumstances that could have material adverse effects on the business, operations, stockholder services, investment performance or reputation of the Fund. Under the overall supervision of the Board or the applicable Committee, the Fund, the Investment Adviser, the Subadviser, and the affiliates of the Investment Adviser and the Subadviser, and other service providers to the Fund employ a variety of processes, procedures and controls to identify various of those possible events or circumstances, to lessen the probability of their occurrence and/or to mitigate the effects of such events or circumstances if they do occur. Different processes, procedures and controls are employed with respect to different types of risks. Various personnel, including the Fund’s and the Investment Adviser’s Chief Compliance Officer and the Investment Adviser’s chief risk officer, as well as various personnel of the Investment Adviser, the Subadviser and other service providers such as the Fund’s independent accountants, also make periodic reports to the Audit Committee, Contracts Committee, Performance Committee and/or to the Board from time to time with respect to various aspects of risk management, as well as events and circumstances that have arisen and responses thereto. These reports and other similar reports received by the Directors as to risk management matters are typically summaries of the relevant information. The Board recognizes that not all risks that may affect the Fund 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 Fund’s goals, and that the processes, procedures and controls employed to address certain risks may be limited in their effectiveness.

Audit Committee. The Board has established an Audit Committee composed solely of Directors who are not “interested persons” (as defined in the 1940 Act) of the Fund; the Investment Advisor or the Subadviser, consisting of Messrs. Abeles, Larson, Poladian, Siart and Taylor and Mses. Dasher, DeFrantz, Kerley and Studenmund. Each member of the Audit Committee is “independent,” as independence for audit committee members is defined in the currently applicable listing standards of the New York Stock Exchange, on which the Common Stock of the Fund is listed and traded. The Audit Committee provides oversight with respect to the accounting and financial reporting policies and procedures of the Fund and, among other things, considers the selection of the independent registered public accounting firm for the Fund and the scope of the audit and approves services proposed to be performed by the independent registered public accounting firm on behalf of the Fund and, under certain circumstances, the Investment Adviser, the Subadviser and certain of their

-11-

affiliates. The Directors have adopted a written charter for the Audit Committee, a copy of which is available on the Fund’s website at www.franklintempleton.com/investments/options/closed-end-funds and click on the name of the Fund.

The Audit Committee has submitted the following report:

The Audit Committee has reviewed and discussed with management of the Fund the audited financial statements for the Fund’s last fiscal year. The Audit Committee has discussed with the Fund’s independent registered public accounting firm the matters required to be discussed by Statement on Auditing Standards No. 1301 (“SAS No. 1301”). SAS No. 1301 requires the independent registered public accounting firm to communicate to the Audit Committee matters including, if applicable: (1) methods used to account for significant unusual transactions; (2) the effect of significant accounting policies in controversial or emerging areas for which there is a lack of authoritative guidance or consensus; (3) the process used by management in formulating particularly sensitive accounting estimates and the basis for the independent registered public accounting firm’s conclusions regarding the reasonableness of those estimates; and (4) disagreements with management over the application of accounting principles and certain other matters. The Audit Committee has received the written disclosures and the letter from the Fund’s independent registered public accounting firm required by Public Company Accounting Oversight Board Rule 3526 (requiring the independent registered public accounting firm to make written disclosures to and discuss with the Audit Committee various matters relating to the independent registered public accounting firm’s independence), and has discussed with such independent registered public accounting firm the independence of such independent registered public accounting firm.

Based on the foregoing review and discussions, the Audit Committee recommended to the Directors the inclusion of the Fund’s audited financial statements for the last fiscal year in the Fund’s annual report to stockholders.

Governance and Nominating Committee. The Board has established a Governance Committee composed solely of Directors who are not “interested persons” (as defined in the 1940 Act) of the Fund, the Investment Adviser or the Subadviser, consisting of Mses. Dasher, DeFrantz (Chairperson), Kerley and Studenmund and Messrs. Abeles, Larson, Poladian, Siart and Taylor. The Governance Committee meets to select nominees for election as Directors of the Fund, and consider other matters of Board policy. The Directors have adopted a written charter for the Governance Committee, a copy of which is available on the Fund’s website at www.franklintempleton.com/investments/options/closed-end-funds and click on the name of the Fund.

The Governance Committee may take into account a wide variety of factors in considering Director candidates, including, but not limited to: (i) availability and commitment of a candidate to attend meetings and perform his or her responsibilities to the Board, (ii) relevant industry and related experience, (iii) educational

-12-

background, (iv) financial expertise, (v) an assessment of the candidate’s ability, judgment and expertise and (vi) overall diversity of the Board’s composition.

The Governance Committee requires that Director candidates have a college degree or equivalent business experience. Further, as required by the Bylaws, to qualify as a nominee for election as a Director and to be elected as a Director, an individual, at the time of nomination and election (unless a majority of the Board then in office have determined by resolution that failure to satisfy a particular qualification requirement will not present undue conflicts or impede the ability of the individual to discharge the duties of a Director or the free flow of information among Directors or between the Fund’s investment adviser and any subadviser on the one hand and the Board on the other hand) must: (a) have at least five years’ experience in either investment management, economics, public accounting, business or law, or other relevant substantive expertise, experience or relationships (as determined by the Governance Committee or the Board); (b) at nomination or election, serve as a director of no more than five (5) companies having securities registered under the Securities Exchange Act of 1934 (the “Exchange Act”) or 1940 Act or treated as public reporting companies under any comparable regulatory regime; (c) not have been charged (unless such charges were dismissed or the individual was otherwise exonerated) with a criminal offense involving dishonesty or breach of trust, or have been convicted or have pled guilty or nolo contendere with respect to a felony under the laws of the United States or any state thereof; (d) not be and shall not have been subject to any censure, order, consent decree or adverse final action of any federal, state or foreign governmental or regulatory authority barring or suspending such individual from participation in or association with any investment-related business or restricting such individual’s activities with respect to any investment-related business, nor shall be subject to any “proceeding,” that could reasonably be expected to result in the nominee or Director being so barred, suspended or restricted; and (e) not be and must not have been the subject of any of the ineligibility provisions contained in Sections 9(a) or (b) of the 1940 Act.

The Governance Committee, or in the absence thereof, the entire Board, in its sole discretion, determines whether an individual satisfies the foregoing qualifications. Any individual who does not satisfy the foregoing qualifications will not be eligible for nomination or election as a Director.

Although the Governance Committee does not have, a formal policy with regard to the consideration of diversity in identifying Director nominees, as a matter of practice the Governance Committee typically considers the overall diversity of the Board’s composition when identifying nominees. Specifically, the Governance Committee considers the diversity of skill sets desired among the Board members in light of the Fund’s characteristics and circumstances and how those skill sets might complement each other. The Governance Committee also takes into account the personal background of current and prospective Directors in considering the composition of the Board. In addition, as part of its annual self-evaluation, the Directors have an opportunity to consider the diversity of the Board, both in terms of skill sets and personal background, and any observations made by the Board during the self-evaluation inform the Governance Committee in its decision making process.

The Governance Committee may consider candidates for Director recommended by the Fund’s current Directors, officers, Investment Adviser, Subadviser, stockholders or any other source deemed to be appropriate by the Governance Committee. Candidates properly submitted by stockholders (as described below) will be considered and evaluated on the same basis as candidates recommended by other sources.

The policy of the Governance Committee is to consider nominees recommended by stockholders to serve as Director, provided that any such recommendation is submitted in writing to the Secretary at the address of

-13-

the principal executive offices of the Fund, not earlier than the 150^th day nor later than 5:00 p.m. Eastern Time on the 120^th day prior to the first anniversary of the date of the proxy statement for the preceding year’s annual meeting containing the information about such nominee required by the Fund’s procedures for stockholders to submit nominee candidates, which are found in the Bylaws. The Governance Committee has full discretion to reject nominees recommended by stockholders, and there is no assurance that any such person so recommended and considered by the Governance Committee will be nominated for election to the Fund’s Board.

Executive and Contracts Committee. The Board has established a Contracts Committee consisting of Messrs. Abeles, Larson, Poladian, Siart (Chairperson), Taylor and Mses. Dasher, DeFrantz, Kerley and Studenmund. The Contracts Committee may meet from time to time between Board meetings in order to consider appropriate matters and to review the various contractual arrangements between the Fund and its affiliated persons.

Investment and Performance Committee. The Board has established a Performance Committee consisting of Messrs. Abeles, Larson, Poladian, Olson, Siart and Taylor and Mses. Dasher, DeFrantz, Kerley (Chairperson), Studenmund and Trust. The Performance Committee is charged with, among other things, reviewing investment performance.

Meetings. During the fiscal year ended December 31, 2022, the Board held six meetings, the Audit Committee held six meetings, the Governance Committee held three meetings, the Performance Committee held five meetings and the Contracts Committee held two meetings. Each Director attended at least 75% of the aggregate number of meetings of the Board and the committees of the Board on which he or she served.

Stockholder Communications. The Board has adopted a process for stockholders to send communications to the Board. Stockholders may mail written communications to the attention of the Board, care of the Fund’s Secretary, at the principal executive offices of the Fund. The written communication must include the stockholder’s name, be signed by the stockholder, refer to the Fund, and include the class and number of shares of Common Stock held by the stockholder as of a recent date. The Secretary is responsible for determining, in consultation with other officers of the Fund, counsel, and other advisers as appropriate, which stockholder communications will be relayed to the Board.

Director Holdings. The following table states the dollar range of equity securities beneficially owned as of December 31, 2022 by each Nominee in the Fund and, on an aggregate basis, in any registered investment companies overseen or to be overseen by the Nominee in the same “family of investment companies.” As of December 31, 2022, all Directors and officers of the Fund as a group beneficially owned less than 1% of the outstanding shares of Common Stock on such date.

The Independent Directors are also reimbursed for all out-of-pocket expenses relating to attendance of such meetings.

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee has selected PricewaterhouseCoopers LLP as the independent registered public accounting firm of the Fund for the fiscal year ending December 31, 2023, and the Board, including a majority of the Independent Directors, has unanimously ratified such selection. PricewaterhouseCoopers LLP’s service is subject to termination by a majority of the outstanding shares of Common Stock of the Fund. A representative of PricewaterhouseCoopers LLP will not be present at the Annual Meeting but will be available by telephone and will have an opportunity to make a statement, if asked, and will be available to respond to appropriate questions.

The following table presents fees billed in each of the Fund’s last two fiscal years for services rendered to the Fund by PricewaterhouseCoopers LLP:

Fiscal year ended	Audit Fees		Audit-Related Fees		Tax Fees		All Other Fees
December 31, 2021	$	39,384	$	0	$	10,000	$	0
December 31, 2022	$	39,384	$	0	$	10,000	$	0

-21-

“Audit Fees” represents fees billed for each of the last two fiscal years for professional services rendered for the audit of the Fund’s annual financial statements for those fiscal years or services that are normally provided by the accountant in connection with statutory or regulatory filings or engagements for those fiscal years.

“Audit-Related Fees” represents fees billed for each of the last two fiscal years for assurance and related services reasonably related to the performance of the audit of the Fund’s annual financial statements for those years.

“Tax Fees” represents fees billed for each of the last two fiscal years for professional services related to tax compliance, tax advice and tax planning, including review or preparation of U.S. federal, state, local and excise tax returns; U.S. federal, state and local tax planning, advice and assistance regarding statutory, regulatory or administrative developments; and tax advice regarding tax qualification matters and/or treatment of various financial instruments held or proposed to be acquired or held.

“All Other Fees” represents fees, if any, billed for other products and services rendered by PricewaterhouseCoopers LLP to the Fund, other than the services described above, for the last two fiscal years.

For the fiscal years ended December 31, 2021 and December 31, 2022, PricewaterhouseCoopers LLP billed aggregate non-audit fees in the amounts of $343,489 and $350,359, respectively, to the Fund, the Investment Adviser and any entity controlling, controlled by or under common control with the Investment Adviser that provides ongoing services to the Fund.

Pre-Approval Policies of the Audit Committee. As noted above, the Audit Committee is governed by the Audit Committee Charter, which includes preapproval policies and procedures. Specifically, the Audit Committee Charter provides:

To carry out its purposes and responsibilities, the Audit Committee shall have the duty and power to:

(h) pre-approve, to the extent contemplated by applicable regulations, audit and non-audit services rendered to the Fund by the auditors and non-audit services rendered to the Managers and certain of their affiliates by the auditors, and review the fees charged by the auditors for such services; provided, however, that the Audit Committee may implement policies and procedures pursuant to which services are pre-approved other than by the full Audit Committee, subject to the requirement that the full Audit Committee be notified at its next meeting of each such service. The Audit Committee has delegated to its Chairperson the authority, on behalf of the Audit Committee, to pre-approve audit and non-audit services rendered to the Fund and non-audit services rendered to the Managers and their affiliates by the auditors; provided that any such pre-approval is reported to the Audit Committee not later than its next meeting.

PricewaterhouseCoopers LLP did not bill any fees for non-audit services performed for the Investment Adviser, and any entity controlling, controlled by or under common control with the Investment Adviser that provides ongoing services to the Fund, that required pre-approval by the Audit Committee pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X during the Fund’s fiscal years ended December 31, 2021 or December 31, 2022. No “Audit-Related Fees,” “Tax Fees” and “Other Fees” set forth in the table above were waived pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

The Audit Committee has considered whether the provision of the non-audit services rendered by PricewaterhouseCoopers LLP to the Investment Adviser and any Service Affiliate that were not required to be

-22-

preapproved by the Audit Committee pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining the independence of PricewaterhouseCoopers LLP.

ADJOURNMENT

The costs of any additional solicitation and of any adjourned session will be borne by the Fund.

At any such adjourned meeting at which a quorum is present, any business may be transacted which might have been transacted at the Annual Meeting as originally called.

-23-

OTHER BUSINESS

The Fund is not aware of any other matters to be presented for action at the Annual Meeting. However, if any such other matters are properly presented, it is the intention of the persons designated in the enclosed proxy to vote in accordance with their best judgment.
