PROPOSAL 1

ELECTION OF BOARD OF TRUSTEES

Introduction

Shareholders of each fund are being asked to consider the election of Mr.
Perna, Ms. Piret and Mr. Ricciardi to the Board of Trustees of each fund. Each
nominee currently serves as a Trustee of each fund and has served in that
capacity continuously since originally elected or appointed.

Mr. Perna, Ms. Piret and Mr. Ricciardi stand for election as their terms expire
in 2018. Each nominee was most recently elected by shareholders in 2015. If
elected, each of Mr. Perna, Ms. Piret and Mr. Ricciardi shall hold office for a
three-year term and until his or her successor is elected and qualified.

Each nominee has consented to being named in this proxy statement and indicated
his or her willingness to serve if elected. In the unanticipated event that any
nominee should be unable to serve, the persons named as proxies may vote for
such other person as shall be designated by the fund's Board of Trustees. The
persons named on the accompanying proxy card intend to vote at the meeting
(unless otherwise directed) for the election of Mr. Perna, Ms. Piret and Mr.
Ricciardi as Trustees of each fund.

Trustee Class Designations and Terms of Office

Each fund's Agreement and Declaration of Trust provides that a majority of the
Trustees shall fix the number of Trustees of the fund and that there shall be
at least one and no more than fifteen Trustees. Each fund currently has nine
Trustees.

The Agreement and Declaration of Trust for each fund provides that the Board of
Trustees shall consist of Trustees divided into three classes, each class to
consist, as nearly as may be possible, of one-third of the total number of
trustees constituting the entire Board of Trustees. Pursuant to each fund's
Agreement and Declaration of Trust, each fund's Board of Trustees is divided
into three staggered term classes - Class I, Class II and Class III. The
Trustees of only one class are elected at each annual meeting so that the
regular term of only one class of Trustees will expire annually and any
particular Trustee stands for election only once in each three-year period.

For each fund, each class of Trustees will stand for election at the conclusion
of its respective three-year term. Such classification may prevent replacement
of a majority of the Trustees for up to a two-year period. Holders of the
Preferred Shares of each fund that has Preferred Shares outstanding are
entitled to elect two trustees of that fund.

Trustee Class Designations and Terms of Office

Currently, the designations and terms of office of each class of Trustees of
each fund are as follows:

Pioneer Diversified High Income Trust

Class I Trustees -- Mr. Friedman, Ms. Graham and Mr. Taubes. Terms expire
in 2020.
Class II Trustees -- Mr. Perna, Ms. Piret and Mr. Ricciardi. Terms expire at the
upcoming 2018 annual meeting. Each Trustee is nominated
for election at the meeting.
Class III Trustees -- Mr. Bock, Ms. Jones and Ms. Monchak. Terms expire
in 2019.

Pioneer Floating Rate Trust, Pioneer Municipal High Income Trust and Pioneer
Municipal High Income Advantage Trust
Class I Trustees -- Mr. Bock, Ms. Jones and Ms. Monchak. Terms expire
in 2019.
Class II Trustees -- Mr. Friedman, Ms. Graham and Mr. Taubes. Terms expire
in 2020.
Class III Trustees -- Mr. Perna, Ms. Piret and Mr. Ricciardi. Terms expire at the
upcoming 2018 annual meeting. Each Trustee is nominated
for election at the meeting.

Pioneer High Income Trust
Class I Trustees -- Mr. Perna, Ms. Piret and Mr. Ricciardi. Terms expire at the
upcoming 2018 annual meeting. Each Trustee is nominated
for election at the meeting.
Class II Trustees -- Mr. Bock, Ms. Jones and Ms. Monchak. Terms expire
in 2019.
Class III Trustees -- Mr. Friedman, Ms. Graham and Mr. Taubes. Terms expire
in 2020.

Mr. Bock and Ms. Piret are designated as the Trustees to be elected by the
holders of the Preferred Shares of each fund that has issued Preferred Shares.
As noted above, Ms. Piret's term expires at the upcoming 2018 annual meeting.
Consequently, holders of Preferred Shares of Pioneer Municipal High Income Trust
and Pioneer Municipal High Income Advantage Trust are being asked to vote as a
separate class at the upcoming 2018 annual meeting to elect Ms. Piret.

With respect to Pioneer Municipal High Income Trust and Pioneer Municipal High
Income Advantage Trust the holders of Common Shares and the holders of Preferred
Shares are being asked to vote together as a single class at the upcoming 2018
annual meeting to

elect Mr. Perna and Mr. Ricciardi. With respect to Pioneer Diversified High
Income Trust, Pioneer Floating Rate Trust and Pioneer High Income Trust the
holders of Common Shares are being asked to vote at the upcoming 2018 annual
meeting to elect Mr. Perna, Ms. Piret and Mr. Ricciardi,

Information Regarding Nominees and Trustees

Responsibilities of the Board of Trustees

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

During the most recent fiscal year of each of Pioneer Floating Rate Trust,
Pioneer High Income Trust, Pioneer Municipal High Income Trust and Pioneer
Municipal High Income Advantage Trust, the Board of Trustees held 6 meetings.
During the most recent fiscal year of Pioneer Diversified High Income Trust, the
Board of Trustees held 7 meetings. All of the current Trustees 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
fiscal year.

The funds do not have a policy on Trustee attendance at the annual meeting of
shareholders. For each fund, no Trustees attended the 2017 annual meeting of
shareholders.

The Trustees 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 willingness and ability to commit the time necessary to perform the
duties of a Trustee; as to each Independent Trustee, 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. Each of the
Independent Trustees also was selected to join the Board based on the criteria
and principles set forth in the Nominating Committee Charter. In addition to
individual attributes, the value of diversity is considered. In evaluating a
Trustee's prospective service on the Board, the Trustee's experience in, and
ongoing contributions toward, overseeing the fund's business as a Trustee also
are considered. In addition, the following specific experience, qualifications,
attributes and/or skills apply as to each Trustee: Mr. Bock, accounting,
financial, business and public company experience as a chief financial officer
and an executive officer and experience as a board member of other
organizations; Mr. Friedman, academic leadership, economic and finance
experience and investment company board experience; Ms. Graham, academic
leadership, experience in business, finance and management consulting; Ms.
Monchak, investment, financial and business experience, including as the chief
investment officer of a pension 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 Pioneer and its affiliates;
and Mr. Taubes, portfolio management experience and leadership roles with
Amundi Pioneer. However, in its periodic assessment of the effectiveness of the
Board, the Board considers the complementary skills and experience of
individual Trustees 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
fund.

Each fund's Agreement and Declaration of Trust provides that the appointment,
designation (including in any proxy or registration statement or other
document) of a Trustee 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, shall not impose on that person any standard of
care or liability that is greater than that imposed on that person as a Trustee
in the absence of the appointment, designation or identification, and no
Trustee who has special attributes, skills, experience or expertise, or is
appointed, designated, or identified as aforesaid, shall be held to a higher
standard of care by virtue thereof.

Board Committees

The Board of Trustees has five standing committees: the Independent Trustees
Committee, the Audit Committee, the Governance and Nominating Committee, the
Policy Administration Committee and the Valuation Committee. Each committee is
chaired by an Independent Trustee and all members of each committee are
Independent Trustees.

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 Trustees
consider and address important matters involving the funds, including those
presenting conflicts or potential conflicts of interest for management. The
Independent Trustees 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

Independent Trustees Committee: David R. Bock, Benjamin M. Friedman, Margaret
B.W. Graham, Lorraine H. Monchak, Thomas J. Perna (Chair), Marguerite A. Piret
and Fred J. Ricciardi.

The Independent Trustees Committee is comprised of all of the Independent
Trustees. The Independent Trustees Committee serves as the forum for
consideration of a number of issues required to be considered separately by the
Independent Trustees under the 1940 Act, including the assessment and review of
each fund's advisory agreement and other

related party contracts. The Independent Trustees Committee also considers
issues that the Independent Trustees believe it is advisable for them to
consider separately from the Interested Trustees.

Audit Committee: David R. Bock (Chair), Benjamin M. Friedman, Lorraine H.
Monchak and Marguerite A. Piret.

Each fund's Audit Committee is comprised of only Independent Trustees who are
"independent" as defined in the applicable New York Stock Exchange ("NYSE") and
NYSE American listing standards relating to closed-end funds. The Board of
Trustees of each fund has adopted a charter for the Audit Committee. In
accordance with its charter, the purposes of the Audit Committee are to:

o Assist the Board of Trustees' oversight and monitoring of: (i) 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,
performance and independence; and (iv) the performance of the fund's
internal audit function; and

o Prepare the disclosure required by Item 407(d)(3)(i) of Regulation S-K
to be included in the fund's annual proxy statement and other filings.

The Audit Committee charter is available on Amundi Pioneer's website:
www.us.pioneerinvestments.com. You also can obtain a copy by sending a written
request to your fund at the address listed on this proxy statement.

Each fund's Board of Trustees has determined that the fund has at least one
audit committee financial expert serving on its Audit Committee. Mr. Bock, an
Independent Trustee, serves on each Audit Committee and has been determined to
be an audit committee financial expert.

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 Statement of Auditing Standards
No. 61, as amended, as adopted by the Public Company Accounting Oversight Board
in Rule 3200 T; and (3) received written disclosures and an independence letter
from the independent registered public accounting firm required by Independence
Standards Board Standard No. 1, as adopted by the Public Company Accounting
Oversight Board in Rule 3600 T, and discussed with the independent registered
public accounting firm that firm's independence. Based upon the review and
discussions referred to above, the Audit Committee recommended to the Board of
Trustees that the audited financial statements be included in the Annual Report
for Pioneer Floating Rate Trust for the fiscal year ended November 30, 2017,
the Annual Reports for Pioneer High Income Trust and Pioneer Municipal High
Income Advantage Trust for the fiscal year ended March 31, 2018 and in the
Annual Reports for Pioneer Diversified High Income Trust and Pioneer Municipal
High Income Trust for the fiscal year ended April 30, 2018.

The members of each fund's Audit Committee are:

David R. Bock (Chair)
Benjamin M. Friedman
Lorraine H. Monchak
Marguerite A. Piret

Governance and Nominating Committee: Margaret B.W. Graham (Chair), Thomas J.
Perna and Fred J. Ricciardi.

All members of the Governance and Nominating Committee are independent under
the applicable NYSE and NYSE American 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's website:
http://us.pioneerinvestments.com. 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 Trustees as a
whole, and reviews and recommends to the Independent Trustees Committee any
appropriate changes concerning, among other things, the size and composition of
the Board, the Board's committee structure and the Independent Trustees'
compensation. The Governance and Nominating Committee also makes
recommendations to the Independent Trustees Committee or the Board on matters
delegated to it.

In addition, the Governance and Nominating Committee screens potential
candidates for Independent Trustees. Among other responsibilities, the
Governance and Nominating Committee reviews periodically the criteria for
Independent Trustees and the spectrum of desirable experience and expertise for
Independent Trustees as a whole, and reviews periodically the qualifications
and requisite skills of persons currently serving as Independent Trustees 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 shareholder or recommended by any Trustee, management or another person
and makes a recommendation as to the qualifications of such nominated or
recommended person to the Independent Trustees and the Board, and reviews
periodically the Committee's procedure, if any, regarding candidates submitted
by shareholders. The Trustees who are not Independent Trustees 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 Trustees
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, 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, to understand the fund and the responsibilities of a trustee of an
investment company; (iv) the nominee's ability to understand the sometimes
conflicting interests of the various constituencies of the fund and to act in
the interests of all shareholders; (v) the absence of a conflict of interest
that would impair his or her ability to represent the interests of all
shareholders and to fulfill the responsibilities of a trustee; and (vi) the
value of diversity on the Board. 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' oversight of each fund's affairs,
based on the then current composition and skills of the Independent Trustees
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. However, as noted above, in its
periodic assessment of the effectiveness of the Board, the Board considers the
complementary skills and experience of individual Trustees 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, 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 Trustee continues, in the opinion of the
other Independent Trustees, to satisfy these criteria and continues to make
positive contributions to the Board, each fund anticipates that Independent
Trustees of the fund would favor the re-nomination of an existing Trustee
rather than a new candidate. Consequently, while the Governance and Nominating
Committee will evaluate the qualifications of nominees recommended by
shareholders to serve as Trustee, the Independent Trustees 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 shareholder recommendations, evaluate candidates identified by
other means, including candidates proposed by Independent Trustees 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 the Governance and Nominating
Committee. In evaluating a nominee recommended by a shareholder, the Governance
and Nominating Committee, in addition to the criteria discussed above, may
consider the objectives of the shareholder in submitting that nomination and
whether such objectives are consistent with the interests of all shareholders.
If the Board determines to include a shareholder's candidate among the slate of
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.

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

Shareholders 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 Trustee 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, Lorraine H. Monchak
and Marguerite A. Piret (Chair).

The Valuation Committee, among other things, determines with Amundi Pioneer 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
and Fred J. Ricciardi.

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, the Board of Trustees has established a framework for the
oversight of various risks relating to the 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, but relies primarily on Amundi Pioneer 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, shareholder 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, 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
shareholders.

Under the overall supervision of the Board or the applicable committee of the
Board, each fund, or Amundi Pioneer and the affiliates of Amundi Pioneer, 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's chief
compliance officer and Amundi Pioneer's chief risk officer and director of
internal audit, as well as various personnel of Amundi Pioneer and of other
service providers, make periodic reports to the applicable committee or to the
Board with respect to various aspects of risk management. The reports received
by the Trustees related to risks typically are summaries of relevant
information.

The Trustees 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 Pioneer 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.

It 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 Trustee or nominee
beneficially owned in each fund and Pioneer Funds in the aggregate as of May
31, 2018. Beneficial ownership is determined in accordance with Securities and
Exchange Commission ("SEC") rules. The share value of any closed-end Pioneer
fund is based on its closing market price on May 31, 2018. The share value of
any open-end Pioneer fund is based on the net asset value of the class of
shares on May 31, 2018. The dollar ranges in this table are in accordance with
SEC requirements.

As of December 31, 2017, the Trustees, any nominee for election as a Trustee
and the officers of each fund owned beneficially in the aggregate less than 1%
of the outstanding shares of each fund.

For each of the funds, during the most recent fiscal year, none of the Trustees
or any nominee for election as a Trustee engaged in the purchase or sale of
securities of Amundi Pioneer, Amundi, Amundi USA, Inc. or any other entity in a
control relationship to Amundi Pioneer or Amundi Pioneer Distributor, Inc.

Compliance with Section 16(a) Reporting Requirements

Section 16(a) of the Exchange Act requires each fund's executive officers,
Trustees and persons who own more than ten percent of a fund's shares ("10%
Shareholders") to file reports of ownership and changes in ownership with the
SEC. Executive officers, Trustees and 10% Shareholders are required by SEC
regulations to furnish the fund with copies of all Section 16(a) forms they
file. Section 30(h) of the 1940 Act extends the reporting requirements under
Section 16(a) of the Exchange Act to certain officers of the fund's investment
adviser. Based solely on a review of the copies of these reports furnished to
each of the funds and representations that no other reports were required to be
filed, each fund believes that during the past fiscal year the filing
requirements applicable to such persons were met.

Executive officers

In addition to Ms. Jones, who serves as the President and Chief Executive
Officer of each fund, the following table provides information with respect to
the other executive officers of the funds. Each executive officer is elected by
the Board of Trustees and serves until his or her successor is chosen and
qualified or until his or her resignation or removal by the Board. The business
address of all officers of the funds is 60 State Street, Boston, Massachusetts
02109.

Investment adviser and administrator

Amundi Pioneer (the "Adviser"), whose executive offices are located at 60 State
Street, Boston, Massachusetts 02109, serves as investment adviser and
administrator to each fund.

Amundi Pioneer is an indirect wholly owned subsidiary of Amundi and Amundi's
wholly owned subsidiary, Amundi USA, Inc. Amundi, one of the world's largest
asset managers, is headquartered in Paris, France. Amundi is majority owned by
Credit Agricole S.A. As of March 31, 2018, Amundi had more than $1.7 trillion in
assets under management worldwide. As of March 31, 2018, Amundi Pioneer (and its
U.S. affiliates) had over $89 billion in assets under management.

On July 3, 2017, Amundi acquired Pioneer Investments, a group of asset
management companies located throughout the world, including each fund's
investment adviser. Prior to July 3, 2017, Pioneer Investments was owned by
Pioneer Global Asset Management S.p.A., a wholly owned subsidiary of UniCredit
S.p.A. ("UniCredit"). Prior to July 3, 2017, each fund's investment adviser was
named Pioneer Investment Management, Inc.

In accordance with the Agreement and Declaration of Trust for each of Pioneer
Diversified High Income Trust, Pioneer Floating Rate Trust and Pioneer High
Income Trust, the affirmative vote of a plurality of the Common Shares of the

respective nominees designated to be elected by such class of shares.

The affirmative vote of a plurality of the Common and Preferred Shares of the

High Income Trust and Pioneer Municipal High Income Advantage Trust
will be elected to the Board of Trustees of such fund.

Recommendation

For the reasons set forth above, the Trustees of your fund unanimously
recommend that shareholders vote FOR each of Mr. Perna, Ms. Piret and Mr.
Ricciardi.

AUDITOR INFORMATION

Each fund's Board of Trustees, with the approval and recommendation of the
Audit Committee, has selected Ernst & Young LLP to serve as the independent
registered public accounting firm for the fund's current fiscal year.

Prior to July 3, 2017, the Adviser was an indirect, wholly owned subsidiary of
UniCredit. On that date, UniCredit completed the sale of its Pioneer
Investments business, which includes the Adviser, to Amundi (the
"Transaction"). As a result of the Transaction, 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 March 31, 2018, had more
than $1.7 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, resigned 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, engaged
a new independent registered public accounting firm, Ernst & Young LLP ("EY"),
for the fund's 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.

Affiliates' Fees for Non-Audit Services Required to be Pre-Approved

Each fund's Audit Committee is required to pre-approve services to affiliates
as defined by SEC rules to the extent that the services relate directly to the
operations or financial reporting of the fund. Affiliates include the fund's
investment adviser and any entity controlling, controlled by, or under common
control with the adviser that provides ongoing services to the fund
(hereinafter referred to as "affiliates" of the fund). For the fiscal years
ended March 31, 2018 and 2017, for Pioneer High Income Trust and Pioneer
Municipal High Income Advantage Trust, there were no services provided to an
affiliate that required the fund's Audit Committee pre-approval. For the fiscal
years ended April 30, 2018 and 2017, for Pioneer Diversified High Income Trust
and Pioneer Municipal High Income Trust, there were no services provided to an
affiliate that required the fund's Audit Committee pre-approval. For the fiscal
years ended November 30, 2017 and 2016, for Pioneer Floating Rate Trust, there
were no services provided to an affiliate that required the fund's Audit
Committee pre-approval.

General Audit Committee Approval Policy

o For all projects, each of the officers of the funds and the funds'
independent registered public accounting firm will make an assessment
to determine that any proposed projects will not impair independence.

o Potential services will be classified into the four non-restricted
service categories and the "Approval of Audit, Audit-Related, Tax and
Other Services" Policy will be applied. Any services outside the
specific pre-approved service subcategories set forth above must
specifically be approved by the Audit Committee.

o At least quarterly, the Audit Committee shall review a report
summarizing the services by service category, including fees, provided
by the independent registered public accounting firm as set forth in
the above policy.

The charter of each Audit Committee requires that the Audit Committee shall
approve (a) all audit and non-audit services to be provided to each fund and
(b) all non-audit services to be provided by the fund's independent public
accounting firm to Amundi Pioneer and any entity controlling, controlled by or
under common control with the investment adviser that provides ongoing services
to the fund ("Covered Service Providers") if the engagement relates directly to
the operations and financial reporting of the fund. The Audit Committee may
delegate, to the extent permitted by law, pre-approval responsibilities to one
or more members of the Audit Committee who shall report to the full Audit
Committee.

No Audit Committee may approve non-audit services that the Audit Committee
believes may impair the independence of the independent registered public
accounting firm. Permissible non-audit services include any professional
services (including tax services) that are not prohibited services as described
below provided to the fund by the independent registered public accounting
firm, other than those provided to a fund in connection with an audit or a
review of the financial statements of the fund. Permissible non-audit services
may not include (a) bookkeeping or other services related to the accounting
records or financial statements of the fund; (b) financial information systems
design and implementation; (c) appraisal or valuation services, fairness
opinions or contribution-in-kind reports; (d) actuarial services; (e) internal
audit outsourcing services; (f) management functions or human resources; (g)
broker or dealer, investment adviser or investment banking services; (h) legal
services and expert services unrelated to the audit; and (i) any other service
the Public Company Accounting Oversight Board determines, by regulation, is
impermissible.

Pre-approval by the Audit Committee of any permissible non-audit services is
not required so long as: (a) the aggregate amount of all such permissible
non-audit services provided to a fund, Amundi Pioneer and any Covered Service
Provider constitutes not more than 5% of the total amount of revenues paid to
the independent registered public accounting firm during the fiscal year in
which the permissible non-audit services are provided to (i) the fund, (ii)
Amundi Pioneer and (iii) any Covered Service Provider during the fiscal year in
which services are provided that would not have to be approved by the Audit
Committee; (b) the permissible non-audit services were not recognized by the
fund at the time of the engagement to be non-audit services; and (c) such
services are promptly brought to the attention of the Audit Committee and
approved by the Audit Committee (or its delegate(s)) prior to completion of the
audit.

Aggregate Non-Audit Fees

The aggregate non-audit fees billed by Ernst & Young LLP and Deloitte & Touche
LLP for services rendered to each fund and its affiliates, as previously
defined, were as follows.

The Audit Committee of the Board of each fund has considered whether the
provision of services, other than audit services, by Ernst & Young LLP to each
fund and its affiliates is compatible with maintaining Ernst & Young LLP's
independence in performing audit services.

Representatives of Ernst & Young LLP will be available at the shareholder
meeting (either in person or via telephone), will have the opportunity to make
a statement should they desire to do so, and will be available to answer
questions.

Shareholder proposals

Under Rule 14a-8 of the Exchange Act (relating to shareholder proposals), any
shareholder proposal that may properly be included in your fund's proxy
statement for the 2019 annual meeting, must be received by the Secretary of the
fund at the fund's principal offices at 60

State Street, Boston, Massachusetts 02109 at least 120 calendar days prior to
the anniversary of the date of mailing of the fund's proxy statement for the
2018 annual meeting, or on or before April 6, 2019. A proposal that is not to
be included in a fund's proxy statement may be made at the 2019 annual meeting
for such fund only if it is received by the Secretary of the fund at the fund's
principal offices at 60 State Street, Boston, Massachusetts 02109 not more than
120 days and at least 90 days before the anniversary date of the mailing of the
fund's proxy materials for the 2018 annual meeting provided, however, that in
the event that the date of the mailing of the notice for the 2019 annual
meeting for a fund is advanced or delayed by more than thirty (30) days from
the anniversary date of the mailing of the notice for the 2018 annual meeting,
notice by a shareholder to be timely must be so delivered not earlier than the
close of business on the 120th day prior to the date of mailing of the notice
for the 2019 annual meeting and not later than the close of business on the
later of the 90th day prior to the date of mailing of the notice for the 2019
annual meeting or the 10th day following the day on which public announcement
of the date of mailing of the notice for the 2019 meeting is first made by the
fund. The funds' By-laws require that certain information must be provided by
the shareholder to the fund when notice of a nominee for election as a Trustee
or proposal is submitted to the fund.

The submission by a shareholder of a proposal for inclusion in a proxy
statement does not guarantee that it will be included. Each of Pioneer
Diversified High Income Trust, Pioneer Floating Rate Trust, Pioneer High Income
Trust, Pioneer Municipal High Income Trust and Pioneer Municipal High Income
Advantage Trust currently expect to hold the next annual shareholders' meeting
on or about September 20, 2019, which date is subject to change. Shareholder
proposals are subject to certain regulations under the federal securities
laws.

Proxies, quorum and voting at the meeting

Any shareholder 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 shareholder present at the meeting may withdraw his or her proxy and
vote in person. 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 shareholders 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, Pioneer Floating Rate Trust
and Pioneer High Income Trust: one-third of the outstanding shares of the fund
entitled to vote, present in person or represented by proxy, constitutes a
quorum for the transaction of business at the meeting.

For each of Pioneer Municipal High Income Trust and Pioneer Municipal High
Income Advantage Trust: one-third of the outstanding Common and Preferred
Shares of the fund entitled to vote, present in person or represented by proxy,
counted together, constitutes a quorum for the transaction of business at the
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.

In the event that at the time any session of the meeting is called to order a
quorum is not present in person or by proxy, the persons named as proxies may
vote those proxies that have been received to adjourn the shareholder meeting
to a later date and the meeting may be held as adjourned without further
notice. In the event that 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 such 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 vote 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
shareholder vote may be taken on one or more of the proposals in the proxy
statement prior to such adjournment if sufficient votes for its approval have
been received and it is otherwise appropriate. 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.

On any matter submitted to a vote of shareholders 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
plurality of the votes cast in person or by proxy at the meeting at which a
quorum exists. Abstentions and "broker non-votes" are not considered "votes
cast" and, therefore, do not constitute a vote "FOR" a proposal. Thus,
abstentions and "broker non-votes" will have no effect on the voting for the
election of Trustees in Proposal 1, because only votes "FOR" are considered in
a plurality voting requirement.

Other business

While the meeting has been called to transact any business that may properly
come before it, the only matters that the Trustees intend to present are those
matters stated in the attached notice of annual meeting of shareholders.
However, if any additional matters properly come before the meeting, and on all
matters incidental to the conduct of the meeting, it is the intention of the
persons named in the enclosed proxy to vote the proxy in accordance with their
judgment 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 shareholders and the accompanying
proxy card for each fund will be borne by that fund. In addition to soliciting
proxies by mail, Amundi Pioneer may, at the fund's expense, have one or more of
the fund's officers, representatives or compensated third-party agents,
including Amundi Pioneer and Amundi Pioneer Distributor, 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 AST Fund Solutions, LLC to assist in
the proxy solicitation. The cost of its services is estimated at
approximately $80,000.

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' identities, to allow
shareholders 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,
shareholders would be called at the phone number the transfer 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 shareholders 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,
shareholders 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.
