The election of a Trustee to a Board requires the affirmative vote of a plurality of the shares entitled to vote for the election of any Trustee present in person or represented by proxy at the Meeting with a quorum present. Under a plurality vote, the nominees who receive the highest number of votes will be elected even if they receive less than a majority of the votes. For purposes of the election of Trustees, abstentions and broker non-votes will be counted as shares present for quorum purposes, but will not be treated as votes cast. Abstentions and broker non-votes, therefore, will have no effect on the election of each Class III Trustee. All properly executed proxies received prior to the Meeting will be voted, at the Meeting or at any adjournments or postponements thereof, in accordance with the instructions marked thereon. Proxies received prior to the Meeting on which no vote is indicated will be voted "FOR" the election of each Class III Trustee.

Brokers holding shares of a 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 before the Meeting. Under the rules of the New York Stock Exchange ("NYSE"), such brokers may, for certain "routine" matters, grant discretionary authority to the proxies designated by the Board to vote if no instructions have been received from their customers and clients prior to the date specified in the brokers' request for voting instructions. Each Proposal is a "routine" matter and accordingly beneficial owners who do not provide proxy instructions or who do not return a proxy card may have their shares voted by broker-dealer firms in favor of the Proposal.

The chairman of the Meeting shall have the power to adjourn the Meeting without further notice other than announcement at the Meeting. Each Board of Trustees also has the power to postpone the Meeting to a later date and/or time in advance of the Meeting. Abstentions and broker non-votes will have the same effect at any adjourned or postponed meeting as noted above. Any business that might have been transacted at the Meeting may be transacted at any such adjourned or postponed session(s) at which a quorum is present.

Written notice of an adjournment of the Meeting, stating the place, date and hour thereof, shall be given to each shareholder entitled to vote thereat at least ten (10) days prior to the Meeting, if the Meeting is adjourned to a date more than one hundred thirty (130) days after the original Record Date set for the Meeting.

We will admit to an Annual Meeting (1) all shareholders of record on February 27, 2020 (the "Record Date"), (2) persons holding proof of beneficial ownership at the Record Date, such as a letter or account statement from the person's broker, (3) persons who have been granted proxies, and (4) such other persons that we, in our sole discretion, may elect to admit. To gain admittance, if you are a shareholder of record or a proxy holder of a shareholder of record, you must bring a form of personal identification to the Meeting, where your name will be verified against our shareholder list. If a broker or other nominee holds your shares and you plan to attend the Meeting, you should bring a recent brokerage statement showing your ownership of the shares, as well as a form of personal identification. If you are a beneficial owner and plan to vote at the Meeting, you should also bring a proxy card from your broker.

Each Board has fixed the close of business on February 27, 2020 as the Record Date for the determination of shareholders entitled to notice of, and to vote at, each Meeting and at any adjournment or postponement thereof.

Each Fund has one class of shares, par value $0.001 per share. Each share of a Fund is entitled to one vote at the Fund's Annual Meeting, and fractional shares are entitled to a proportionate share of one vote. On the Record Date, the following number of shares of each Fund were issued and outstanding:

The Election of Class III Trustees

Pursuant to each Fund's Agreement and Declaration of Trust, each Board is divided into three classes, as nearly equal in number as possible, each of which will serve for three years, with one class being elected each year. If elected, each Trustee is entitled to hold office until the Annual Meeting in the year noted below or until his or her successor is elected and qualifies. Trustees who are deemed "interested persons" (as that term is defined in Section 2(a)(19) of the 1940 Act), of a Fund or Aberdeen Asset Managers Limited ("AAML" or the "Investment Adviser"), are referred to in this Proxy Statement as "Interested Trustees." Trustees who are not interested persons, as described above, are referred to in this Proxy Statement as "Independent Trustees."

Each Fund's Board, including the Independent Trustees, upon the recommendation of such Board's Nominating and Corporate Governance Committee, which is composed entirely of Independent Trustees, has nominated the following nominees as Class III Trustees to its Board as follows:

The nominees have indicated an intention to serve as a Class III Trustee if elected and have consented to be named in this Proxy Statement.

It is the intention of the persons named as proxies on the enclosed Proxy Card(s) to vote "FOR" the election of the nominees for Class III Trustees to serve for a three-year term. Each Fund's Board knows of no reason why the nominees would be unable to serve, but in the event of any such inability, the proxies received will be voted for such substituted nominee as such Fund's Board may recommend.

The following tables set forth certain information regarding the nominees for election to the Boards of the Funds, Trustees whose terms of office continue beyond the Meetings, and the principal officers of the Funds.

ADDITIONAL INFORMATION ABOUT THE TRUSTEES

Each Board believes that each Trustee's experience, qualifications, attributes and skills on an individual basis and in combination with those of the other Trustees lead to the conclusion that the Trustees possess the requisite experience, qualifications, attributes and skills to serve on their respective Board. Each Board believes that the Trustees' ability to review critically, evaluate, question and discuss information provided to them; to interact effectively with the Investment Adviser, other service providers, counsel and independent auditors; and to exercise

effective business judgment in the performance of their duties, support this conclusion. Each Board has also considered the contributions that each Trustee can make to the respective Board on which he or she serves and to the Fund(s).

A Trustee's ability to perform his or her duties effectively may have been attained through the Trustee's executive, business, consulting, and/or legal positions; experience from service as a Trustee of the Fund(s) and other funds/portfolios in the Aberdeen Standard complex, other investment funds, public companies, or non-profit entities or other organizations; educational background or professional training or practice; and/or other life experiences. In this regard, the following specific experience, qualifications, attributes and/or skills apply as to each Trustee in addition to the information set forth in the table above: Ms. Maasbach, financial and research analysis experience in and covering the Asia region and experience in world affairs; Mr. Malone, legal background and public service leadership experience, board experience with other public and private companies, and executive and business consulting experience; Mr. Sievwright, banking and accounting experience and experience as a board member of public companies; Mr. Gilbert is a founder and Chairman of a global asset management company with experience as a board member of other investment trusts and a member of several financial organizations.

Each Board believes that the significance of each Trustee's experience, qualifications, attributes or skills is an individual matter (meaning that experience important for one Trustee may not have the same value for another) and that these factors are best evaluated at the Board level, with no single Trustee, or particular factor, being indicative of Board effectiveness. In its periodic self-assessment of the effectiveness of the Board, each Board considers the complementary individual skills and experience of the individual Trustees in the broader context of the Board's overall composition so that the Board, as a body, possesses the appropriate (and appropriately diverse) skills and experience to oversee the business of the Fund. References to the qualifications, attributes and skills of Trustees are presented pursuant to disclosure requirements of the Securities and Exchange Commission ("SEC"), do not constitute holding out a Board or any Trustee as having any special expertise or experience, and shall not impose any greater responsibility or liability on any such person or on a Board by reason thereof.

*  Officers hold their positions with the Fund until a successor has been duly elected and qualifies. Officers are elected annually at a meeting of the Board of Trustees.

**  Messrs. Andolina, Connaghan Cotton, Duitz Goodson, Hendry, and Pittard and Mses. Ferrari, Hasson, Kennedy, Melia and Sitar hold one or more officer positions with one or more of the following funds: Aberdeen Australia Equity Fund, Inc., Aberdeen Asia-Pacific Income Fund, Inc., Aberdeen Funds, Aberdeen Investment Funds, Aberdeen Emerging Markets Equity Income Fund, Inc., Aberdeen Japan Equity Fund, Inc., The India Fund, Inc., Aberdeen Global Dynamic Dividend Fund, Aberdeen Total Dynamic Dividend Fund, Aberdeen Global Premier Properties Fund, Aberdeen Standard Investments ETFs, and Aberdeen Income Credit Strategies Fund each of which may be deemed to be part of the same "Fund Complex" as the Fund.

Ownership of Securities

Set forth in the table below is the dollar range of equity securities in each Fund and the aggregate dollar range of equity securities in the Aberdeen Family of Investment Companies (as defined below) beneficially owned by each Trustee or nominee as of March 17, 2020. The following key relates to the dollar ranges in the chart:

A. None
B. $1 — $10,000
C. $10,001 — $50,000
D. $50,001 — $100,000
E. over $100,000

(1)  This information has been furnished by each Trustee as of March 17, 2020. "Beneficial ownership" is determined in accordance with Rule 16a-1(a)(2) promulgated under the Securities Exchange Act of 1934, as amended (the "1934 Act").

(2)  "Family of Investment Companies" means those registered investment companies that share Aberdeen or an affiliate as the investment adviser and that hold themselves out to investors as related companies for purposes of investment and investor services.

As of March 17, 2020, each Fund's Trustees and officers, in the aggregate, owned less than 1% of that Fund's outstanding equity securities. As of March 17, 2020, none of the Independent Trustees or their immediate family members owned any shares of the Investment Adviser of any person (other than a registered investment company) directly or indirectly controlling, controlled by, or under common control with the Investment Adviser.

Mr. Pittard and Ms. Melia serve as executive officers of the Funds. As of March 17, 2020, Mr. Pittard and Ms. Melia did not own shares of the Funds.

BOARD AND COMMITTEE STRUCTURE

The Board of Trustees of each Fund is composed of four Trustees, three of whom are not "interested persons" (as that term is defined in the Investment Company Act of 1940 ("1940 Act")) of the Fund, its Investment Adviser (each an "Independent Trustee," and collectively, the "Independent Trustees"). Each Fund divides the Board into three classes, each class having a term of three years. Each year, the term of office of one class will expire and the successor(s) elected to such class will serve for a three year term.

Each Board has appointed Mr. Malone, an Independent Trustee, as Chairman. The Chairman presides at meetings of the Trustees, participates in the preparation of the agenda for meetings of the Board, and acts as a liaison between the Trustees and management between Board meetings. Except for any duties specified herein, the designation of the Chairman does not impose on such Trustee any duties, obligations or liability that is greater than the duties, obligations or liability imposed on such person as a member of the Board, generally.

Each Board holds regular quarterly meetings to consider and address matters involving the respective Fund. Each Board also may hold special meetings to address matters arising between regular meetings. The Independent

Trustees also meet outside the presence of management in executive session at least quarterly and have engaged separate, independent legal counsel to assist them in performing their oversight responsibilities.

Each Board has established a committee structure that includes an Audit and Valuation Committee and a Nominating and Corporate Governance Committee (each discussed in more detail below) to assist each Board in the oversight and direction of the business affairs of the respective Fund, and from time to time may establish informal ad hoc committees or working groups to review and address the practices of the respective Fund with respect to specific matters. The Committee system facilitates the timely and efficient consideration of matters by the Trustees, and facilitates effective oversight of compliance with legal and regulatory requirements and of each Fund's activities and associated risks. The standing Committees currently conduct an annual review of their charters, which includes a review of their responsibilities and operations.

Each Nominating and Corporate Governance Committee and each Board as a whole also conduct an annual self-assessment of the performance of the Board, including consideration of the effectiveness of the Board's Committee structure. Each Committee is comprised entirely of Independent Trustees. Each Committee member is also "independent" within the meaning of the NYSE listing standards. Each Board reviews its structure regularly and believes that its leadership structure, including having a super-majority of Independent Trustees, coupled with an Independent Trustee as Chairman, is appropriate because it allows the Board to exercise informed and independent judgment over the matters under its purview and it allocates areas of responsibility among the Committees and the full Board in a manner that enhances efficient and effective oversight.

Board and Committee Meetings in Fiscal Year 2019

During the fiscal year ended October 31, 2019, each Board held four quarterly meetings and one special meeting. During such fiscal year, based on available records, the Trustees serving during that fiscal year attended at least 75% of the aggregate number of meetings of the Boards and of the Committees of the Boards on which they served.

Audit and Valuation Committee

Each Board has an Audit and Valuation Committee consisting of all the Independent Trustees. In addition, the members of the Audit and Valuation Committee are also "independent," as defined in the Fund's written Audit and Valuation Committee Charter. The members of each Audit and Valuation Committee are Ms. Maasbach, Mr. Malone and Mr. Sievwright. Mr. Sievwright serves as the Chairman of each Audit and Valuation Committee and the Audit Committee Financial Expert.

The Audit and Valuation Committees oversee the scope of each Fund's audit, such Fund's accounting and financial reporting policies and practices and its internal controls. The Audit and Valuation Committees assist the Boards in fulfilling their responsibilities for oversight of the integrity of the Funds' accounting, auditing and financial reporting practices, the qualifications and independence of the Funds' independent registered public accounting firm and the Funds' compliance with legal and regulatory requirements. The Audit and Valuation Committees approve, and recommend to the Boards for ratification, the selection, appointment, retention or termination of the Funds' independent registered public accounting firm and approves the compensation of the independent registered public accounting firm. The Audit and Valuation Committees also approve all audit and permissible non-audit services provided to the Funds by the independent registered public accounting firm and all permissible non-audit services provided by the Funds' independent registered public accounting firm to the Investment Adviser and service providers if the engagement relates directly to the Funds' operations and financial reporting. The Audit and Valuation Committees are also responsible for monitoring the valuation of portfolio securities and other investments. The written Charters for the Audit and Valuation Committees are available at the Funds' websites at www.aberdeenaod.com and www.aberdeenagd.com. During the fiscal year ended October 31, 2019, each Audit and Valuation Committee met 5 times.

Service providers to the Funds, primarily the Investment Adviser, have responsibility for the day-to-day management of the Funds, which includes responsibility for risk management. As an integral part of its responsibility for oversight of the Funds, the Boards oversee risk management of the Funds' investment program and business affairs. Oversight of the risk management process is part of the Boards' general oversight of the Funds and their service providers.

Nominating and Corporate Governance Committee; Consideration of Potential Trustee Nominees

Each Board has a Nominating and Corporate Governance Committee (the "Nominating Committee") consisting of all the Independent Trustees. The members of the Nominating Committee are Ms. Maasbach, Mr. Malone and Mr. Sievwright. Mr. Malone serves as the Chairman of the Nominating Committees.

Each Nominating Committee is responsible for overseeing Board governance and related Trustee practices, including selecting and recommending candidates to fill vacancies on the Board. The Nominating Committees will consider Trustee candidates recommended by shareholders of the Funds. Recommendations for consideration by a Nominating Committee should be sent to the Chairman of the Nominating Committee in writing together with the appropriate biographical information concerning each such recommended nominee. In addition, shareholders may themselves nominate individuals for election to a Board of Trustees for the Funds if they follow the advance notice provisions in the Funds' By-Laws, as more fully set forth on page 17.

In identifying and evaluating nominees for Trustee, the Nominating Committees seek to ensure that the Boards possess, in the aggregate, the strategic, managerial and financial skills and experience necessary to fulfill its duties and to achieve its objectives, and also seeks to ensure that the Boards of Trustees are comprised of trustees who have broad and diverse backgrounds. The Nominating Committees look at each nominee on a case-by-case basis. In looking at the qualification of each candidate to determine if his or her election would further the goals described above, each Nominating Committee takes into account all factors it considers appropriate, which may include strength of character, mature judgment, career specialization, relevant technical skills or financial acumen, diversity of viewpoint and industry knowledge. However, a Board believes that to be recommended as a nominee, whether by the Nominating Committees or at the suggestion of a shareholder, each candidate must: (1) display the highest personal and professional ethics, integrity and values; (2) have the ability to exercise sound business judgment; (3) be highly accomplished in his or her respective field; (4) have relevant expertise and experience; (5) be able to represent all shareholders and be committed to enhancing long-term shareholder value; and (6) have sufficient time available to devote to activities of the Board and enhance his or her knowledge of the Fund's business. The Nominating Committees met two times during the fiscal year ended October 31, 2019. The Board has adopted a written Charter for the Nominating Committee, which is available at the Funds' websites at www.aberdeenaod.com and www.aberdeenagd.com.

Board Oversight of Risk Management

Each Fund is subject to a number of risks, including, among others, investment, compliance, operational and valuation risks. Risk oversight forms part of each Board's general oversight of the respective Fund and is addressed as part of various Board and Committee activities. Each Board has adopted, and periodically reviews, policies and procedures designed to address these risks. Different processes, procedures and controls are employed with respect to different types of risks. Day-to-day risk management functions are subsumed within the responsibilities of the Funds' Investment Adviser, who carry out the Funds' investment management and business affairs and other service providers in connection with the services they provide to the Funds. The Investment Adviser and other service providers have their own, independent interest in risk management, and their policies and methods of risk management will depend on their functions and business models. As part of its regular oversight of each Fund, the respective Board, directly and/or through a Committee, interacts with and reviews reports from, among others, the Investment Adviser and each Fund's other service providers (including the Funds' transfer agent), the Funds' Chief

Compliance Officer, the Funds' independent registered public accounting firm, legal counsel to the Funds, and internal auditors, as appropriate, relating to the operations of the Funds. Each Board also requires the Investment Adviser to report to the Boards on other matters relating to risk management on a regular and as-needed basis. The Boards recognize that it may not be possible to identify all of the risks that may affect the Funds or to develop processes and controls to eliminate or mitigate their occurrence or effects. Each Board may, at any time and in its discretion, change the manner in which it conducts risk oversight.

Communications with the Board of Trustees

Shareholders who wish to communicate with Board members with respect to matters relating to the Funds may address their written correspondence to the Boards as a whole or to individual Board members c/o Aberdeen Standard Investments Inc., at 1900 Market Street, Suite 200, Philadelphia, PA 19103, or via e-mail to the Trustee(s) c/o Aberdeen Standard Investments Inc. at Investor.Relations@aberdeenstandard.com.

Trustees Attendance at Annual Meetings of Shareholders

The Funds have not established a formal policy with respect to Trustee attendance at annual meetings of shareholders.

The following table sets forth the aggregate fees billed for professional services rendered by KPMG during the Fund's two most recent fiscal years ended October 31:

(1) Services include tax services in connection with the Fund's excise tax calculations and review of the Fund's applicable tax returns.

Each Audit and Valuation Committee is responsible for pre-approving (i) all audit and permissible non-audit services to be provided by the independent registered public accounting firm to each Fund and (ii) all permissible non-audit services to be provided by the independent registered public accounting firm to the Fund's Investment Adviser, and any service provider to a Fund controlling, controlled by or under common control with the Fund's Investment Adviser that provided ongoing services to the Fund ("Covered Service Provider"), if the engagement relates directly to the operations and financial reporting of the Fund. The aggregate fees billed by KPMG for non-audit services rendered to the Fund, the Investment Adviser and any Covered Service Providers for the fiscal year ended October 31, 2019 was $620,687, and for the fiscal year ended October 31, 2018 was $764,339.

All of the services described in the table above were pre-approved by the relevant Audit and Valuation Committee.

Each Audit and Valuation Committee has adopted an Audit Committee Charter that provides that the Audit and Valuation Committee shall annually select, retain or terminate, and recommend to the Independent Trustees for their ratification, the selection, retention or termination, the Funds' independent auditor and, in connection therewith, evaluate the terms of the engagement (including compensation of the auditor) and the qualifications and independence of the independent auditor, including whether the independent auditor provides any consulting, auditing or tax services to the Investment Adviser, and receive the independent auditor's specific representations as to its independence, delineating all relationships between the independent auditor and the Fund, consistent with the Independent Standards Board ("ISB") Standard No. 1. Each Audit and Valuation Committee Charter also provides that the Committee shall review in advance, and consider approval of, any and all proposals by Fund management or the Investment Adviser that the Funds, Investment Adviser or their affiliated persons, employ the independent auditor to render "permissible non-audit services" to the Fund and to consider whether such services are consistent with the independent auditor's independence.

Each Audit and Valuation Committee has considered whether the provision of non-audit services that were rendered to the Investment Adviser and any entity controlling, controlled by, or under common control with these entities that provides ongoing services to the Fund that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining the principal accountant's independence and has concluded that it is independent.

COMPENSATION

The following table sets forth information regarding compensation of Trustees from the Funds for the fiscal year ended October 31, 2019. All officers of the Funds are employees of and are compensated by the Funds'

Investment Adviser or its affiliates. None of the Funds' executive officers or Trustees who are also officers or directors of AAML or ASII received any compensation from any Fund for such period. None of the Funds have any bonus, profit sharing, pension or retirement plans.

*  See the "Trustees" table for the number of Funds within the Fund Complex that each Trustee servces.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the 1934 Act and Section 30(h) of the 1940 Act, as applied to the Funds, require the Funds' officers and Trustees, certain officers and directors of the investment advisers, affiliates of the investment advisers, and persons who beneficially own more than 10% of the Fund's shares to electronically file reports of ownership of the Funds' securities and changes in such ownership with the SEC and the NYSE.

Based solely on each Fund's review of such forms filed on EDGAR or written representations from reporting persons that all reportable transactions were reported, to the knowledge of each Fund, during the fiscal year ended October 31, 2019, each Fund's officers, Trustees and greater than 10% owners timely filed all reports they were required to file under Section 16(a).

Relationship of Trustees or Nominees with the Investment Adviser

AAML serves as Investment Adviser to each Fund pursuant to individual advisory agreements dated May 4, 2018. AAML with its registered office at 10 Queen's Terrace, Aberdeen, Scotland AB10 1YG, is a corporation organized under the laws of Scotland and a U.S. registered investment adviser. AAML provides equity, fixed income and real estate advisory services, as well as alternative strategies.

In rendering investment advisory services, ASII and AAML may use the resources of investment advisor subsidiaries of Standard Life Aberdeen. These affiliates have entered into a memorandum of understanding/personnel sharing procedures pursuant to which investment professionals from each affiliate may render portfolio management and research services to US clients of the Standard Life Aberdeen affiliates, including the Funds, as associated persons of the Investment Adviser. No remuneration is paid by the Funds with respect to the memorandum of understanding/personnel sharing arrangements.

EACH FUND'S BOARD, INCLUDING THE INDEPENDENT TRUSTEES, RECOMMENDS THAT THE SHAREHOLDERS VOTE "FOR" THE NOMINEES AS CLASS III TRUSTEES.

ADDITIONAL INFORMATION

Administrator. State Street Bank & Trust Company, located at 1 Heritage Drive, 3^rd Floor, North Quincy, MA 02171, serves as administrator to the Funds.

Expenses. The expense of preparation, printing and mailing of the enclosed proxy card and accompanying Notice and Joint Proxy Statement will be borne proportionately by each Fund. Each Fund will reimburse banks, brokers and others for their reasonable expenses in forwarding proxy solicitation material to the beneficial owners of the shares of that Fund. In order to obtain the necessary quorum at each Meeting, supplementary solicitation may be made by mail, telephone, telegraph or personal interview. Such solicitation may be conducted by, among others, officers, Trustees and employees of the Funds, or AAML or its affiliates.

AST Fund Solutions, LLC ("AST") has been retained to assist in the solicitation of proxies and will receive an estimated fee of $2,500 per Fund and be reimbursed for its reasonable expenses. Total payments for the Funds to AST are expected to be between approximately $3,270 and $3,410 per Fund.

Solicitation and Voting of Proxies. Solicitation of proxies is being made primarily by the mailing of this Joint Proxy Statement with its enclosures on or about March 23, 2020. As mentioned above, AST has been engaged to assist in the solicitation of proxies. As the date of the Meetings approach, certain shareholders of a Fund may receive a call from a representative of AST, if the Fund has not yet received their vote. Authorization to permit AST to execute proxies may be obtained by telephonic instructions from shareholders of a Fund. Proxies that are obtained telephonically will be recorded in accordance with procedures that management of each of the Funds believes are reasonably designed to ensure that the identity of the shareholder casting the vote is accurately determined and that the voting instructions of the shareholder are accurately determined.

Beneficial Owners. Based upon filings made with the SEC, as of February 28, 2020, the following table shows certain information concerning persons who may be deemed beneficial owners of 5% or more of the shares of the Funds because they possessed or shared voting or investment power with respect to a Fund's shares:

shareholder contemplating submission of a proposal for inclusion in the Fund's proxy materials is referred to Rule 14a-8 under the 1934 Act.

Non-Rule 14a-8 proposals of business to be considered by the Funds' shareholders may be made at an annual meeting of shareholders (1) by or at the direction of the Boards of Trustees or (2) by any shareholder of a Fund who was a shareholder of record from the time the shareholder gave notice as provided in the Funds' By-Laws to the time of the annual meeting, who is entitled to vote at the annual meeting on any such business and who has complied with the By-Laws. Pursuant to each Fund's By-Laws, for any such business to be properly brought before an annual meeting by a shareholder, the shareholder must have given timely notice thereof in writing to the Secretary of the Funds and such business must otherwise be a proper matter for action by the shareholders. To be timely, a shareholder's notice shall set forth all information required under the Fund's By-Laws and shall be delivered to the Secretary of the Funds at the principal executive office of the Fund neither earlier than 9:00 a.m., Eastern Time, on the 150^th day nor later than 5:00 p.m., Eastern Time, on the 120^th day before the first anniversary of the date of the proxy statement for the preceding year's annual meeting; provided, however, that in the event the date of the annual meeting is advanced or delayed by more than 30 days from the first anniversary of the date of the preceding year's annual meeting, or in the event that no annual meeting was held the preceding year, notice by the shareholder will be timely if so delivered not later than 5:00 p.m., Eastern Time, on the tenth day following the day on which public announcement of the date of such annual meeting is first made. The public announcement of a postponement or adjournment of an annual meeting shall not commence a new time period for the giving of a shareholder's notice as described above.

On February 7, 2020, the Funds announced the date of the Meetings and noted that based on the shareholder's notice described above, each shareholder had an opportunity to submit Rule 14a-8 proposals by February 21, 2020 and Non-Rule 14a-8 proposals by February 17, 2020. The Funds did not receive notice of any proposed matter to be submitted by shareholders for a vote at this Meeting and, therefore, in accordance with Rule 14a-4(c) under the 1934 Act any proxies held by persons designated as proxies by each Board and received in respect of the Meetings will be voted in their discretion on such other matter which may properly come before each Meeting.

In accordance with Rule 14a-4(c), each Fund may exercise discretionary voting authority with respect to any shareholder proposals for this Annual Meeting not included in the proxy statement and form of proxy card which are not submitted to the Fund within the time-frame indicated above. Even if timely notice is received, a Fund may exercise discretionary voting authority in certain other circumstances permitted by Rule 14a-4(c) and SEC guidance related thereto. Discretionary voting authority is the ability to vote proxies that shareholders have executed and returned to a Fund on matters not specifically reflected on the form of proxy card.

SHAREHOLDERS WHO DO NOT EXPECT TO BE PRESENT AT THE MEETINGS AND WHO WISH TO HAVE THEIR SHARES VOTED ARE REQUESTED TO DATE AND SIGN THE ENCLOSED PROXY CARD(S) AND RETURN THEM IN THE ENCLOSED ENVELOPE. NO POSTAGE IS REQUIRED IF MAILED IN THE UNITED STATES.
