* Mr. Baumgardner is Of Counsel to Sullivan & Cromwell LLP, which acts as
independent outside legal counsel to the Independent Directors of each
Pioneer Fund.

** Ms. Jones and Mr. Taubes are Interested TrusteesDirectors because they are an
officer or director of each fund's investment adviser and certain of its
affiliates.

Responsibilities of the Board of TrusteesDirectors

The Board of TrusteesDirectors 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 High Income Fund, Inc., Pioneer Municipal High Income Fund,
Inc. and Pioneer Municipal High Income Advantage Fund, Inc., the Board of
TrusteesDirectors held 710 meetings. During the most recent fiscal year of Pioneer
Floating Rate Fund, Inc., the Board of

Directors held 13 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
TrusteesDirectors 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.stockholders. For each fund, one TrusteeDirector attended the 20162020 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 Governance and Nominating Committee Charter.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, 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 Maryland General Corporation Law, 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 TrusteesDirectors 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 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:

consideration of a number of issues required to be considered separately by the
Independent TrusteesDirectors under the 1940 Act, including the assessment and review
of each fund's advisory agreement and other related party contracts. The
Independent TrusteesDirectors Committee also considers issues that the Independent
TrusteesDirectors believe it is advisable for them to consider separately from the

integrity of the fund's financial statements; (ii) the fund's
compliance with legal and regulatory requirements; (iii) the
independent registered public accounting firm's qualifications,

Audit Committee Report

The Audit Committee reports that it has (1) reviewed and discussed each fund's
audited financial statements with management; (2) discussed with the
independent registered public accounting firm the matters required to be
discussed with the independent auditors by the Statementapplicable requirements of Auditing Standards
No. 61, as amended, as adopted by the Public Company Accounting
Oversight Board in Rule 3200 T;and the SEC; and (3) received written disclosures and an independencethe
letter from the independent registered public accounting firm required by
Independence
Standards Board Standard No. 1, as adopted byapplicable requirements of the Public Company Accounting Oversight Board
in Rule 3600 T,regarding the independent registered public accounting firm's communications
with the Audit Committee concerning independence, and discussed with the
independent registered public accounting firm that firm's independence. Based

fiscal year ended March 31, 20172021 and in the Annual Reports for Pioneer
Diversified High Income TrustFund, Inc. and Pioneer Municipal High Income TrustFund, Inc.
for the fiscal year ended April 30, 2017.

2021.

The members of each fund's Audit Committee are:

David R. Bock (Chair)Diane Durnin
Benjamin M. Friedman
Craig C. MacKay
Lorraine H. Monchak
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
and Nominating Committee, which is available on Amundi Pioneer'sUS's website:
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 and expertise
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 of Directors with respect to attributes such
as race, ethnicity, gender, cultural background, skills 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

to high ethical standards; (ii) the nominee's
business acumen and ability to exercise sound judgment in matters that relate
to the 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 of the fund, including those of stockholders and the management
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'22

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 Charter 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 shareholderstockholder 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 lawsBylaws of the fund to be
considered by the Governance and Nominating Committee. 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 TrusteesDirectors 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'sstockholder's
candidate will be treated as a nominee of the shareholderstockholder 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.

ShareholdersStockholders 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.

Valuation Committee: David R. Bock, Benjamin M. Friedman, Craig C. MacKay, Lorraine H.
Monchak,
and Marguerite A. Piret (Chair)., and Fred J. Ricciardi.

The Valuation Committee, among other things, determines with Amundi PioneerUS the
value of securities under certain circumstances and considers other matters
with respect to the valuation of securities, in each case in accordance with
each fund's valuation procedures.

Policy Administration Committee: Margaret B.W. Graham (Chair), Thomas J. Perna (Chair), John E. Baumgardner,
Jr., and Fred J. Ricciardi.Marguerite A. Piret.

The Policy Administration Committee, among other things, oversees and monitors
each fund's compliance with legal and regulatory requirements that are not
directly related to financial reporting, internal financial controls,
independent audits or the performance of the fund's internal audit function.
The Policy Administration Committee also oversees the adoption and
implementation of certain of the funds' policies and procedures.

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 managementDirectors has established a framework for the
oversight of each fund's
investment management and business operations. In performing this oversight
function, the Board considers 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 TrusteesDirectors recognize 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.

beneficially owned in each fund and Pioneer Funds in the aggregate as of May
31, 2017.2021. Beneficial ownership is determined in accordance with Securities

S.p.A. ("UniCredit"). Prior to July 3, 2017, each fund's investment adviser was
named Pioneer Investment Management, Inc.

Planned redemptions of auction preferred shares

On July 13, 2017, the Adviser announced that each of Pioneer Municipal High
Income Advantage Trust and Pioneer Municipal High Income Trust intends to
redeem all of their outstanding auction preferred shares (APS) at the
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
the closing conditions of the new financing. Specific information related to
the redemption process and timeframes will be released by the funds separately.
The Adviser expects the redemptions to be completed by the end of 2017.

After the refinancing is completed, each fund will continue to employ financial
leverage for investment purposes. The Adviser does not expect the refinancing
to reduce either fund's leverage outstanding.

AUDITOR INFORMATION

Prior to July 3, 2017,Each fund's Board of Directors, 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.

the date of the mailing of the notice for the 20182022 annual meeting for a fund is
advanced or delayed by more than thirty (30) days from the 40

anniversary date of
the mailing of the notice for the 20172021 annual meeting, notice by a shareholderstockholder
to be timely must be so delivered not earlier than the close of business on the
120th150th day prior to the date of mailing of the notice for the 20182022 annual
meeting and not later than the close of business on the later of the 90th120th day
prior to the date of mailing of the notice for the 20182022 annual meeting or the
10th day following the day on which public announcement of the date of mailing
of the notice for the 20182022 meeting is first made by

the fund. The funds' By-lawsBylaws require that certain information must be provided
by the shareholderstockholder to the fund when notice of a nominee for election as a
TrusteeDirector or proposal is submitted to the fund.

The submission by a shareholderstockholder of a proposal for inclusion in a proxy
statement does not guarantee that it will be included. Each of Pioneer
Diversified High Income Trust,Fund, Inc., Pioneer Floating Rate Trust,Fund, Inc., Pioneer
High Income Trust,Fund, Inc., Pioneer Municipal High Income TrustFund, Inc. and Pioneer
Municipal High Income Advantage TrustFund, Inc. currently expect to hold the next
annual shareholders'stockholders' meeting on or about September 19, 2018,14, 2022, which date is
subject to change. ShareholderStockholder proposals are subject to certain regulations
under the federal securities laws.

Proxies, quorum and voting at the meeting

Any shareholderstockholder who has given his or her proxy to someone generally has the
power to revoke that proxy at any time prior to its exercise 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 use their best judgment in connection with the
transaction of such other business as may properly come before the meeting or
any adjournment or postponement thereof.

Only shareholdersstockholders of record as of 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
TrustFund, Inc. and Pioneer High Income Trust: one-third ofFund, 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
Income Advantage Trust: one-thirdFund, Inc.: with respect to matters to be voted on by the
Common Stock and the Preferred Stock of a fund voting together as a single
class, the outstanding Common and Preferred
Shares of the fund entitled to vote, presentpresence in person or represented by proxy counted together, constitutesof stockholders entitled to cast a
majority of the votes entitled to be cast at the meeting by holders of stock of
such fund on such matters shall constitute a quorum for the transaction of
business at the fund's meeting; with respect to matters to be voted on the
Preferred Stock of a 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 by holders of stock of such class on such matters shall
constitute a quorum for the transaction of business at the fund's meeting.

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" indicates on the proxy card that it does not have
discretionary authority to vote on

a proposal and has not received instructions from the beneficial owner.
41

InHowever, because the eventfunds understand that a broker or nominee may exercise
discretionary voting power with respect to Proposal 1, and there are no other
proposals expected to come before the meeting 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. InAt the event thatdiscretion 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.is present. Abstentions and "broker non-votes" are
not considered "votes cast" and, therefore, do not constitute a vote "FOR" a
proposal. Thus,
abstentionsAbstentions and "broker non-votes"broker non-votes will have no effect on the results
of the voting foron Proposal 1. However, because the election of Trustees infunds 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 TrusteesDirectors intend 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 in the enclosed proxy toas proxies will vote the proxy in accordance withat 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,

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.$55,000.

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 shareholderstockholder 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.
