Pioneer Fund.

Responsibilities of the Board of TrusteesDirectors

The Board of Trustees is responsible for overseeing each fund's management and operations.
The Chairman of the Board is an Independent Trustee.Director. Independent TrusteesDirectors
constitute at least 75% of the Board.

During each fund'sthe most recent fiscal year of each of Pioneer Diversified High Income
Fund, Inc., Pioneer Municipal High Income Fund, Inc. and Pioneer Municipal High
Income Advantage Fund, Inc., the Board of Trustees held 7 meetings. During the most recent
fiscal year of each of Pioneer Floating Rate Fund, Inc. and Pioneer High Income
Fund, Inc., the Board held 8 meetings. During the most recent fiscal year of
Pioneer Municipal High Income Opportunities Fund, Inc., the Board held 4
meetings. All of the current TrusteesDirectors and committee members of each fund then
serving attended at least 75% of the meetings of the Board of Trustees and applicable
committees, if any, held during that fund's most recent fiscal year.

The funds do not have a policy on TrusteeDirector attendance at the annual meeting of
shareholders.meeting.
For each fund, one TrusteeDirector attended the 20162021 annual meeting of shareholders.

stockholders.

The TrusteesDirectors were selected or nominated to join the Board based upon the
following as to each Board member: such person's character and integrity; such
person's judgment, analytical ability, intelligence, and common sense; such
person's experience and previous profit and not-for-profit board membership;
such person's demonstrated willingness to take an independent and questioning
stance toward management; such person's willingness and ability to commit the
time necessary to perform the duties of a Trustee;Director; as to each Independent
Trustee,Director, his or her status as not being an "interested person" as defined
under the 1940 Act; and, as to Ms. Jones and Mr. Taubes, their association with
Amundi Pioneer.US. Each Director also serves on the Boards of Directors of other
exchange-listed closed-end funds, closed-end interval funds, and open-end
funds, all part of the Pioneer Funds complex, and has substantial experience
protecting fund stockholders' interests. As part of their service on the boards
of Pioneer closed-end funds', the nominees regularly evaluate issues unique to
closed-end funds, including the discount at which closed-end funds' shares may
trade relative to their net asset value per share. Each of the Independent
TrusteesDirectors also was selected to join the Board based on the criteria and
principles set forth in the charter of each fund's Governance and Nominating
Committee, Charter.as then in effect. In addition to individual attributes, the value
of diversity is considered. In evaluating a
Trustee'san incumbent Director's prospective
service on the Board, the Trustee'sDirector's experience in, and ongoing contributions
toward, overseeing the fund's business as a TrusteeDirector also are considered.

In addition, the following specific experience,experiences, qualifications, attributes
and/or skills apply as to each Trustee:Director: Mr. Bock, accounting,
financial,Baumgardner, legal, investment
management, business and public company experience as a chief financial officeran attorney practicing
investment management, corporate and an executive officersecurities law and experience as a board
member of other organizations; Ms. Durnin, investment management and investment
company experience as an executive officer of an investment adviser; Mr.
Friedman, academic leadership, economic and finance experience and investment
company board experience; Ms. Graham, academic
leadership,Mr. MacKay, investment, financial and business
experience as a partner in business, financean investment banking firm and management consulting;experience as a board
member

of other organizations; Ms. Monchak, investment, financial and business
experience, including as the chief investment officer of a pension fund.fund; Mr.
Perna, accounting, financial, and business experience as an executive officer
and experience as a board member of other organizations; Ms. Piret, accounting,
financial and entrepreneurial experience as an executive, valuation experience
and investment company board experience; Mr. Ricciardi, financial, business and
investment company experience as an executive officer of a financial and
investment company services organization, and experience as a board member of
offshore investment companies and other organizations; Ms. Jones, investment
management experience as an executive and leadership roles with Amundi PioneerUS and
its affiliates,affiliates; and Mr. Taubes, portfolio management experience and leadership
roles with Amundi Pioneer.US. However, in its periodic assessment of the effectiveness
of the Board, the Board considers the complementary skills and experience of
individual TrusteesDirectors primarily 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
funds.

Each fund's Agreement and Declaration of Trust provides thatfund.

Under the MGCL, the appointment, designation (including in any proxy or
registration statement or other document) of a TrusteeDirector as an expert on any
topic or in any area, or as having experience, attributes or skills in any
area, or any other appointment, designation or identification, shalldoes not impose
on that person any standard of care or liability that is greater than that
imposed on that person as a TrusteeDirector in the absence of the appointment,
designation or identification, and no TrusteeDirector who has special attributes,
skills, experience or expertise, or is appointed, designated, or identified as
aforesaid, shall beis held to a higher standard of care by virtue thereof.

Board Committees

The Board of Trustees has five standing committees: the Independent TrusteesDirectors Committee,
the Audit Committee, the Governance and Nominating Committee, the Policy
Administration Committee and the Valuation Committee. Each committee is chaired
by an Independent TrusteeDirector (the "Chairs") and all members of each committee are
Independent Trustees.Directors.

The Chairs of the committees work with the Chairman of the Board and fund
management in setting the agendas for Board meetings. The Chairs of the
committees set the agendas for committee meetings with input from fund
management. As noted below, through the committees, the Independent TrusteesDirectors
consider and address important matters involving the funds, including those
presenting conflicts or potential conflicts of interest for management. The
Independent TrusteesDirectors also regularly meet without the presence of management
and are advised by independent legal counsel. The Board believes that the
committee structure, and delegation to the committees of specified oversight
responsibilities, help the Board more effectively to provide governance and
oversight of the funds' affairs. Mr. Perna, Chairman of the Board, is a member
of each committee except the Audit Committee and the Valuation Committee, of
each of which he is a non-voting, ex-officio member.

During the most recent fiscal year for each fund, the Audit, Governance and
Nominating, Independent Trustees,Directors, Policy Administration and Valuation
Committees of each fund held the following meetings:

Marguerite A. PiretFred J. Ricciardi (Chair)

Governance and Nominating Committee: Margaret B.W. GrahamJohn E. Baumgardner, Jr. (Chair), Diane
Durnin, and Thomas J. Perna and Fred J. Ricciardi.Perna.

All members of the Governance and Nominating Committee are independent under
the applicable NYSE and NYSE MKTAmerican listing standards relating to closed-end
funds, and are not "interested persons," as defined in the 1940 Act, of each
fund. The Board of each fund has adopted a written charter for the Governance

http://us.pioneerinvestments.com.amundi.com/US. You also can obtain a copy by sending a written request to your
fund at the address listed on this proxy statement.

The Governance and Nominating Committee considers governance matters affecting
the Board and each fund. Among other responsibilities, the Governance and
Nominating Committee reviews the performance of the Independent TrusteesDirectors as a
whole, and reviews

and recommends to the Independent TrusteesDirectors Committee any appropriate changes
concerning, among other things, the size and composition of the Board, the
Board's committee structure and the Independent Trustees'Directors' compensation. The
Governance and Nominating Committee also makes recommendations to the
Independent TrusteesDirectors Committee or the Board on matters delegated to it.

In addition, the Governance and Nominating Committee screens potential
candidates for Independent Trustees.Directors. Among other responsibilities, the
Governance and Nominating Committee reviews periodically the criteria for
Independent TrusteesDirectors and the spectrum of desirable experience, expertise and
expertisecharacteristics for Independent TrusteesDirectors as a whole, and reviews periodically
the qualifications and requisite skills of persons currently serving as
Independent TrusteesDirectors and being considered for re-nomination. The Governance
and Nominating Committee also reviews the qualifications of any person
nominated to serve on the Board by a shareholderstockholder or recommended by any
Trustee,Director, management or another person and makes a recommendation as to the
qualifications of such nominated or recommended person to the Independent
TrusteesDirectors and the Board, and reviews periodically the Committee's procedure, if
any, regarding candidates submitted by shareholders.stockholders. The TrusteesGovernance and
Nominating Committee also strives to achieve diversity of the Board with
respect to attributes such as race, ethnicity, gender, cultural background and
professional experience when reviewing candidates for any Board vacancies. The
Directors who are not Independent TrusteesDirectors and the officers of each fund are
nominated and selected by the Board.

The Governance and Nominating Committee does not have specific, minimum
qualifications for nominees, nor has it established specific qualities or
skills that it regards as necessary for one or more of the Independent
TrusteesDirectors to possess (other than qualities or skills that may be required by
applicable law or regulation). However, in evaluating a person as a potential
nominee to serve as an Independent Trustee,Director, the Governance and Nominating
Committee will consider the following general criteria and principles, among
any others that it may deem relevant: (i) the nominee's reputation for
integrity, honesty and adherence 20

to high ethical standards; (ii) the nominee's
business acumen and ability to exercise sound judgment in matters that relate
to the current and long-term objectives of the fund and whether the person is
willing and able to contribute positively to the decision-making process of the
fund; (iii) the nominee's commitment and ability to devote the necessary time
and energy to be an effective Independent Trustee,Director, to understand the fund and
the responsibilities of a trusteedirector of an investment company; (iv) the nominee's
ability to understand the sometimes conflicting interests of the various constituencies offund and the
fundmanagement company, and to act in the interests of all shareholders;stockholders; (v) whether
the absence ofnominee has, or appears to have, a conflict of interest that would impair
his or her ability to represent the interests of all shareholdersstockholders and to
fulfill the responsibilities of a trustee;director; and (vi) the value of diversitythat nominees shall not be
discriminated against on the Board.basis of race, religion, national origin, sex,
sexual orientation, disability or any other basis proscribed by law. The
Governance and Nominating Committee also will consider whether the nominee has
the experience or skills that the Governance and Nominating Committee believes
would maintain or enhance the effectiveness of the Independent Trustees'Directors'
oversight of each fund's affairs, based on the

then current composition and skills of the Independent TrusteesDirectors and experience
or skills that may be appropriate in light of changing business conditions and
regulatory or other developments. The Governance and Nominating Committee does
not necessarily place the same emphasis on each criterion.

The Governance and Nominating Committee does not have a formal procedure for
the implementation, or for assessing the effectiveness, of its policy with
regard to the consideration of the value of diversity on the Board in reviewing
potential nominees for Independent Trustee.Director. However, as noted above, in its
periodic assessment of the effectiveness of the Board, the Board considers the
complementary skills and experience of individual TrusteesDirectors in the 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 funds. In addition, as noted above, the Governance and
Nomination Committee Chartercharter provides that nominees shall not be discriminated
against on the basis of race, religion, national origin, sex, sexual
orientation, disability or any other basis proscribed by law.

As long as an existing Independent TrusteeDirector continues, in the opinion of the
other Independent Trustees,Directors, to satisfy these criteria and continues to make
positive contributions to the Board, each fund anticipates that Independent
TrusteesDirectors of the fund would favor the re-nomination of an existing TrusteeDirector
rather than a new candidate. Consequently, while the Governance and Nominating
Committee will evaluate the qualifications of nominees recommended by
shareholdersstockholders to serve as Trustee,Director, the Independent TrusteesDirectors might act upon the
Governance and Nominating Committee's evaluation only if there is a vacancy on
the Board. In the event that a vacancy arises or a change in Board membership
is determined to be advisable, the Governance and Nominating Committee will, in
addition to any shareholderstockholder recommendations, evaluate candidates identified by
other means, including candidates proposed by Independent TrusteesDirectors or
management. While it has not done so in the past, the Governance and Nominating
Committee may retain a consultant to assist the Committee in a search for a
qualified candidate.

Any shareholder recommendation must be submitted in compliance with all of the
pertinent provisions of Regulation 14A under the Securities Exchange Act of
1934, as amended (the "Exchange Act"), and the Agreement and Declaration of
Trust and By laws of the fund to be considered by theThe Governance and Nominating Committee.Committee will consider recommendations for board
membership by stockholders. In evaluating a nominee recommended by a
shareholder,stockholder, the Governance and Nominating Committee, in addition to the
criteria discussed above, may consider the objectives of the shareholderstockholder in
submitting that nomination and whether such objectives are consistent with the
interests of all shareholders.stockholders. If the Board determines to include a
shareholder'sstockholder's candidate among the slate of Board nominees, the candidate's name
will be placed on the fund's proxy card. If the
Governance and Nominating Committee, the Independent Trustees or the Board
determines not to include such candidate among the Board's designated nominees
and the shareholder has satisfied the requirements of Rule 14a-8 under the
Exchange Act, the shareholder's candidate will be treated as a nominee of the
shareholder who originally nominated the candidate.

The Governance and Nominating Committee initiated the recommendation of each of
the non-interested nominees to serve as an Independent Trustee.Director.

With respect to the re-nomination of an existing Independent Trustee,Director, the
Governance and Nominating Committee and the Independent TrusteesDirectors Committee use
the criteria and the principles set forth above, as revised from time to time,
to guide the selection process.

Stockholders may communicate with the members of the Board as a group or
individually. Any such communication should be sent to the Board or an
individual TrusteeDirector c/o the Secretary of the fund at the address on the notice
of this meeting. The Secretary may determine not to forward any communication
to members of the Board that does not relate to the business of a fund.

Oversight of Risk Management

Consistent with its responsibility for oversight of each fund in the interests
of shareholders,stockholders, the Board of Trustees oversees risk management of each fund's
investment management and business operations. In performing thishas established a framework for the oversight function, the Board considersof
various risks and risk management practices relating to the funds.funds, including the oversight of the
identification of risks and the management of certain identified risks. The
Board has delegated certain aspects of its risk oversight responsibilities to
the committees.committees, but relies primarily on Amundi US and its affiliates for the
identification and management or mitigation of risks relating to their
management activities on behalf of the funds, as well as to oversee and advise
the Board on the risks that may arise relating to the activities of other fund
service providers.

Each fund faces a number of risks, such as investment risk, counterparty risk,
valuation risk, enterprise risk, reputational risk, cybersecurity risk, risk of
operational failure or lack of business continuity, and legal, compliance and
regulatory risk. The goal of risk management is to identify and address risks,
i.e., events or circumstances that could have material adverse effects on the
business, operations, shareholderstockholder services, investment performance or
reputation of a fund.

Most of the funds' investment management and business operations are carried
out by or through Amundi Pioneer,US, its affiliates, and other service providers (such
as the custodian and fund accounting agent and the transfer agent), each of
which has an independent interest in risk management but whose policies and the
methods by which one or more risk management functions are carried out may
differ from each fund's and each other's in the

setting of priorities, the resources available or the effectiveness of relevant
controls. Operational or other failures, including cybersecurity failures, at
any one or more of the funds' service providers could have a material adverse
effect on a fund and its stockholders.

Under the overall supervision of the Board or the applicable committee of the
Board, each fund, or Amundi PioneerUS and the affiliates of Amundi PioneerUS, or other
service providers to each fund employ a variety of processes, procedures and
controls in an effort to identify, address and mitigate risks. Different
processes, procedures and controls are employed with respect to different types
of risks. Various personnel, including the funds' and Amundi Pioneer'sUS's chief
compliance officer and Amundi Pioneer'sUS's chief risk officer and director of internal
audit, as well as various personnel of Amundi Pioneer,US and theof other service
providers, make periodic reports to the applicable committee or to the Board
with respect to various aspects of risk management, and the applicable
committee of the Board review Financial Intermediary Controls and Compliance
Assessment ("FICCA") reports if available.management. The reports received by the
TrusteesDirectors related to risks typically are summaries of relevant information.

The Trustees recognizeBoard recognizes that not all risks that may affect a 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 each fund's goals, that the processes,
procedures and controls employed to address certain risks may be limited in
their effectiveness, and that some risks are simply beyond the control of the
funds or Amundi PioneerUS and its affiliates or other service providers. Because most
of the funds' operations are carried out by various service providers, the
Board's oversight of the risk management processes of those service providers,
including processes to address cybersecurity and other operational failures, is
inherently limited. As a result of the foregoing and other factors, each fund's
ability to manage risk is subject to substantial limitations.

In addition, itIt is important to note that each fund is designed for investors that are
prepared to accept investment risk, including the possibility that as yet
unforeseen risks may emerge in the future.

The following table indicates the value of shares that each TrusteeDirector or nominee
beneficially owned in each fund and Pioneer Funds in the aggregate as of May
31, 2017.2022. Beneficial ownership is determined in accordance with Securities
and Exchange Commission ("SEC") rules.SEC Rule
13d-3(d)(1). The share value of any closed-end Pioneer fund is based on its
closing market price on May 31, 2017.2022. The share value of any open-end Pioneer
fund is based on the net asset value of the class of shares on May 31, 2017.2022.

liquidation preference per share (sometimes referred to as "at par") of each
series of APS, together with accrued and unpaid dividends, if any, as of the
redemption date.

Each fund's Board of Trustees has approved a refinancing plan expected to
result in the redemption of all of each fund's outstanding APS. The redemption
of each fund's APS is subject to the successful negotiation of the new
financing, the satisfaction of certain notice and regulatory requirements, and

AUDITOR INFORMATION

Prior to July 3, 2017,Each fund's Board, with the Adviser was an indirect, wholly owned subsidiary of
UniCredit. On that date, UniCredit completed the sale of its Pioneer
Investments business, which included the Adviser, to Amundi (the
"Transaction"). As a resultapproval and recommendation of the Transaction,Audit Committee,
has selected Ernst & Young LLP to serve as the Adviser became an indirect,
wholly-owned subsidiary of Amundi. Amundi is controlled by Credit Agricole S.A.
Amundi is headquartered in Paris, France, and, as of June 30, 2017, Amundi had
more than $1.5 trillion in assets under management worldwide.

Deloitte & Touche LLP, each fund's previous independent registered public
accounting firm informed the Audit Committee and the Board that it would no
longer be independent with respect to the funds upon the completion of the
Transaction as a result of certain services being provided to Amundi and Credit
Agricole, and, accordingly, that it intended to resign as each fund's
independent registered public accounting firm upon the completion of the
Transaction. Deloitte & Touche LLP's resignation was effective on July 3, 2017,
when the Transaction was completed.

During the periods as to which Deloitte & Touche LLP has served as each fund's
independent registered public accounting firm, including each fund's two most
recent fiscal years preceding the fiscal year ended June 30, 2017, Deloitte &
Touche LLP's reports on each fund's financial statements have not contained an
adverse opinion or disclaimer of opinion and have not been qualified or
modified as to uncertainty, audit scope or accounting principles. Further,
there have been no disagreements with Deloitte & Touche LLP on any matter of
accounting principles or practices, financial statement disclosure, or auditing
scope or procedure, which, if not resolved to the satisfaction of Deloitte &
Touche LLP, would have caused Deloitte & Touche LLP to make reference to the
subject matter of the disagreement in connection with its report on the
financial statements. In addition, there have been no reportable events of the
kind described in Item 304(a)(1)(v) of Regulation S-K under the Securities
Exchange Act of 1934.

Effective immediately following the completion of the Transaction on July 3,
2017, the Board, acting upon the recommendation of the Audit Committee, with
respect to each Fund, engaged a new independent registered public accounting
firm, Ernst & Young LLP ("EY"), for the fund's current fiscal year ending November 30,
2017 (for Pioneer Floating Rate Trust), March 31, 2018 (for Pioneer High Income
Trust and Pioneer Municipal High Income Advantage Trust) or April 30, 2018 (for
Pioneer Diversified High Income Trust and Pioneer Municipal High Income Trust),
as applicable.

Prior to its engagement, EY had advised each fund's Audit Committee that EY had
identified the following matters, in each case relating to services rendered by
other member firms of Ernst & Young Global Limited, all of which are located
outside the United States, to UniCredit and certain of its subsidiaries during
the period commencing July 1, 2016, that it determined to be inconsistent with
the auditor independence rules set forth by the SEC: (a) project management
support services to UniCredit in the Czech Republic, Germany, Italy, Serbia and
Slovenia in relation to twenty-two projects, that were determined to be
inconsistent with Rule 2-01(c)(4)(vi) of Regulation S-X (management functions);
(b) two engagements for UniCredit in Italy where fees were contingent/success
based and that were determined to be inconsistent with Rule 2-01(c)(5) of
Regulation S-X (contingent fees); (c) four engagements where legal and expert
services were provided to UniCredit in the Czech Republic and Germany, and
twenty engagements where the legal advisory services were provided to UniCredit
in Austria, Czech Republic, Italy and Poland, that were determined to be
inconsistent with Rule 2-01(c)(4)(ix) and (x) of Regulation S-X (legal and
expert services); and (d) two engagements for UniCredit in Italy involving
assistance in the sale of certain assets, that were determined to be
inconsistent with Rule 2-01(c)(4)(viii) of Regulation S-X (broker-dealer,
investment advisor or investment banking services). None of the foregoing
services involved a fund, any of the other funds in the Pioneer Family of Funds
or any other Pioneer entity sold by UniCredit in the Transaction.

EY advised the Audit Committee that it had considered the matters described
above and had concluded that such matters would not impair EY's ability to
exercise objective and impartial judgment in connection with the audits of the
financial statements of each fund under the SEC and Public Company Accounting
Oversight Board independence rules, and that a reasonable investor with
knowledge of all relevant facts and circumstances would reach the same
conclusion. Management and the Audit Committee considered these matters and
discussed the matters with EY and, based upon EY's description of the matters
and statements made by EY, Management and the Audit Committee believe that EY
will be capable of exercising objective and impartial judgment in connection
with the audits of the financial statements of each fund, and Management
further believes that a reasonable investor with knowledge of all relevant
facts and circumstances would reach the same conclusion.year.

Any shareholderStockholders who has given hisexecute proxies or her proxy to someoneprovide voting instructions by telephone or
the Internet generally hashave the power to revoke that proxythem at any time prior to its exercisebefore a vote
is taken on a proposal by executing a superseding proxy or by submitting a
notice of revocation to the Secretary of the fund. In addition, although mere
attendance at the meeting will not revoke a proxy, a shareholderstockholder present at the
meeting may withdraw his or her proxy and vote in person.at the meeting. All properly
executed and unrevoked proxies received in time for the meeting will be voted
in accordance with the instructions contained in the proxies. If no instruction
is given, the persons named as proxies will vote the shares represented thereby
in favor of Proposal 1, as described above, and will usevote in their best judgmentdiscretion
in connection with the transaction of such other business as may properly come
before the meeting or any adjournmentpostponements or postponementadjournments thereof.

Only shareholdersstockholders of record as of the close of business on the record date are
entitled to notice of and to vote at the meeting.

For each of Pioneer Diversified High Income Trust,Fund, Inc., Pioneer Floating Rate
Trust
andFund, Inc., Pioneer High Income Trust: one-third ofFund, Inc. and Pioneer Municipal High Income
Opportunities Fund, Inc.: the outstanding shares of the fund
entitled to vote, presentpresence in person or represented by proxy constitutesof stockholders
entitled to cast a majority of the votes entitled to be cast at the meeting by
holders of stock of such fund shall constitute a quorum for the transaction of
business at the meeting.

For each of Pioneer Municipal High Income TrustFund, Inc. and Pioneer Municipal High

outstanding Common Stock and Preferred SharesStock of a fund voting together as a single class,
the fund entitled to vote, presentpresence in person or represented by proxy counted together, constitutesof stockholders entitled to cast a majority

such matters shall constitute a quorum for the transaction of business on such

fund voting as a separate class, the presence in person or by proxy of
stockholders entitled to cast a majority of the votes entitled to be cast at
the meeting.meeting by holders of stock of such class on such matters shall constitute
a quorum for the transaction of business on such matters.

Abstentions and "broker non-votes" will be treated as present for purposes of
determining a quorum. "Broker non-votes" occur when a broker or nominee holding
shares in "street name" indicatesdoes not vote on a proposal because the proxy card that itbroker or
nominee does not have discretionary authority to vote on a proposalvoting power for that particular item and
has not received instructions from the beneficial owner. 41However, because the
funds understand that a broker or nominee may

Inexercise discretionary voting power with respect to Proposal 1, and there are
no other proposals expected to come before the eventmeeting for which a broker or
nominee would not have discretionary voting authority, the funds do not
anticipate that there will be any "broker non-votes" at the time any sessionmeeting.

The meeting with respect to one or more funds may, by action of the chair of
the meeting is calledand without any action by stockholders, be adjourned from time to
order a
quorum is not present in persontime with respect to one or by proxy,more matters to be considered at the persons named as proxies may
vote those proxies that have been received to adjourn the shareholder meeting to a
later date and time and at a place announced at the meeting, whether or not a
quorum is present with respect to such matter, and the meeting may be held as
adjourned without further notice. Innotice other than announcement at the eventmeeting and
provided that the new meeting date is not more than 120 days from the original
record date. At the discretion of the chair, if a quorum is present but sufficient votes in favor of
the proposal have not been received, the persons named as proxies may propose
one or more adjournments of the shareholder meeting to permit further
solicitation of proxies with
respect to sucha proposal and the meeting may be
held as adjourned without further notice. Any such adjournment will require the
affirmative vote of more than one half of the shares of the fund present in
person or by proxy on the motion for adjournment at the session of the meeting to be adjourned. The persons named as proxies will vote those proxies which
they are entitled to vote in favor of any such proposal, or that abstained, in
favor of such an adjournment and will vote those proxies required to be voted
against any such proposal against any such adjournment. Unless a proxy is
otherwise limited in this regard, any shares present and entitled to voteconsidered at the meeting, that are represented by broker non-votes may, at the discretion of
the proxies named therein, be voted in favor of such an adjournment. A
shareholdera vote may be taken on
one or more of the proposals in the proxy
statementproposal prior to such adjournment if sufficient votes for its approval have
been received and it is otherwise appropriate.adjournment. Such vote will be considered final
regardless of whether the meeting is adjourned to permit additional
solicitation with respect to any other
proposal. The meeting may be postponed prior to the meeting. If the meeting is
postponed, the funds will give notice of the postponed meeting to shareholders.stockholders.

On any matter submitted to a vote of shareholdersstockholders each whole share shall be
entitled to one vote as to any matter on which it is entitled to vote and each
fractional share shall be entitled to a proportionate fractional vote.

As discussed more fully under Proposal 1 above, nominees must be elected by a
pluralitymajority of all the votes entitled to be cast in person or by proxy at thea meeting of stockholders duly
called and at which a quorum exists. Abstentions and "broker non-votes"is present. Because the required vote for Proposal
1 is based on the number of votes the fund's stockholders are not considered "votes
cast" and, therefore, do not constitute aentitled to cast
rather than on the number of votes cast, failure to vote "FOR" a proposal. Thus,your shares (including
failure to give voting instructions to your broker, bank or other nominee),
abstentions and "broker non-votes" will have nothe same effect on theas voting
for"AGAINST" the election of Trustees inthe directors. However, because the funds understand
that a broker or nominee may exercise discretionary voting power with respect
to Proposal 1, because only votes "FOR"and there are considered inno other proposals expected to come before the
meeting for which a pluralitybroker or nominee would not have discretionary voting
requirement.authority, the funds do not anticipate that there will be any "broker
non-votes" at the meeting.

Other business

While the meeting has been called to transact any business that may properly
come before it, the only matters that the Trustees intendBoard intends to present are those
matters stated in the attached notice of annual meeting of shareholders.stockholders.
However, if any additional matters properly come before the annual stockholder
meeting, and on all matters incidental to the conduct of the meeting, it is the intention of the
persons named as proxies will vote in the enclosed proxy to vote the proxy in accordance with their judgmentdiscretion on such matters unless
instructed to the contrary.

Method of solicitation and expenses

The cost of preparing, printing and mailing the enclosed proxy statement,
accompanying notice of annual meeting of shareholdersstockholders and the accompanying
proxy card for each fund will be borne by that fund. In addition to soliciting
proxies by mail, Amundi PioneerUS may, 42

at the

fund's expense, have one or more of the fund's officers, representatives or
compensated third-party agents, including Amundi PioneerUS and Amundi Pioneer
Distributor US,
Inc., aid in the solicitation of proxies by personal interview or telephone and
may request brokerage houses and other custodians, nominees and fiduciaries to
forward proxy soliciting material to the beneficial owners of the shares held
of record by such persons. Each fund has retained Broadridge
Financial Solutions, Inc.Di Costa Partners, LLC to
assist in the proxy solicitation. The cost of their services for all solicitations
covered by this proxy statement is estimated at approximately $80,000.$68,000.

Each fund may also arrange to have votes recorded by telephone, the internet or
other electronic means. The voting procedures used in connection with such
voting methods are designed to authenticate shareholders'stockholders' identities, to allow
shareholdersstockholders to authorize the voting of their shares in accordance with their
instructions and to confirm that their instructions have been properly
recorded. If these procedures were subject to a successful legal challenge,
such votes would not be counted at the shareholder meeting. Each fund is
unaware of any such challenge at this time. In the case of telephone voting, shareholdersstockholders would be called at the
phone number the sub-transfertransfer agent, American Stock Transfer & Trust Company, has
in its records for their accounts, and would be asked for their Social Security
number or other identifying information. The shareholdersstockholders would then be given
an opportunity to authorize proxies to vote their shares at the meeting in
accordance with their instructions. In the case of automated telephone and
internet voting, shareholdersstockholders would be required to provide their Social
Security number or other identifying information and would receive a
confirmation of their instructions.

Persons holding shares as nominees will be reimbursed by the fund, upon
request, for the reasonable expenses of mailing soliciting materials to the
principals of the accounts.
