Dear Shareowner,
--------------------------------------------------------------------------------
Staying diversified and keeping your portfolio invested in the markets are two
general investment principles that have served investors well over time. They
were particularly useful guides in recent months, when an otherwise healthy
long-term bull market was buffeted by problems in the mortgage and banking
industries.
Since mid-year 2007, issues tied to poor underwriting practices in the subprime
sector of the mortgage industry and to problems with risk management by banks
and hedge funds have resulted in increased market volatility and rising concern
about risks to U.S. economic growth.
U.S. economic growth had slowed over the past two years, but this has been due
as much to the natural maturation of the cyclical expansion, as U.S. factories
approached full utilization and the labor market approached full employment, as
to rising commodity prices or short-term interest rates. The slowdown was,
therefore, not entirely unwelcome, as it reduced the threat of higher inflation.
More recently, however, there has been increasing concern that falling home
prices, and/or disruptions in financial markets pose a larger threat to
continuing economic growth, and we have seen two cuts in short-term interest
rates from the Federal Reserve despite strong economic growth in the second and
third quarters of this year. A weaker U.S. dollar has put upward pressure on
some prices, but it has also significantly benefited exporters and companies
competing in the global marketplace, stimulating U.S. economic growth.
Economic growth in the rest of the world remains relatively positive. In Europe,
solid GDP growth has driven unemployment lower and supported growing
consumption, although concerns about the impact of the strong Euro are a
persistent source of worry. Japanese economic growth continues, albeit at a
muted rate, and the country's deflationary problems are gradually receding.
Economic growth in emerging market countries remains faster than in the
developed world, led by China, which continues its rise as a world economic
power.
Looking forward, the economic outlook continues to appear generally positive,
although real estate prices, subprime mortgage defaults, and the possibility of
a liquidity/credit crunch represent growing sources of risk. Central banks have
responded to the stresses in the inter-bank and commercial paper markets by
acting as "lenders of last resort" and, in the case of the Federal Reserve, by
cutting rates.
The U.S. Federal Reserve and the world's other central banks continue to pursue
policies aimed at producing low and stable inflation, believed to be the best
backdrop for steady economic growth and low average unemployment over the long
term. Keeping inflation low is also an important support for stock and bond
valuations, and so central bank
2
Letter
policies have also been "investor friendly." We view the Fed's recent rate cuts
as temporarily "buying insurance" against a credit crunch, which would threaten
economic growth rather than as an abandonment of its commitment to keeping
inflation low.
Even against this "wall of worry" backdrop, major asset classes produced
generally positive returns in the six-months ending October 31, 2007. Equity
investors were by and large rewarded as, despite several interim corrections,
the Standard & Poor's 500 Index returned 5%, the Dow Jones Industrial Average
returned 8%, and the NASDAQ Composite Index returned 13%. International
developed market equities performed comparably, with the MSCI EAFE Developed
Market Index returning 8% over the six-month period; emerging markets equities
performed better, with the MSCI Emerging Markets Index returning 40%. The U.S.
bond market, as measured by the Lehman Aggregate Bond Index, returned 3% in the
six-month period. The U.S. high-yield bond market, as measured by the Merrill
Lynch High Yield Bond Master II Index, returned 0% for the same period, as its
higher coupon yield was offset by price declines as yields rose on perceptions,
of increasing credit risk.
Sudden swings in the markets are always to be expected. Just as staying
diversified and invested are important investment principles, it is also
important to pay attention to asset allocation. As always, we encourage you to
work closely with your financial advisor to find the mix of stocks, bonds and
money market assets that is best aligned to your particular risk tolerance and
investment objective.
Respectfully,
/s/ Daniel K. Kingsbury

PORTFOLIO MANAGEMENT DISCUSSION 10/31/07
--------------------------------------------------------------------------------
During one of the most turbulent periods for fixed-income investments, investors
in Pioneer Municipal High Income Trust earned a relatively high level of
tax-free income. In the following interview, David Eurkus, a member of the
Pioneer fixed-income management team, discusses some of the factors that had an
impact on the municipal bond market and the Trust.
Q: How did the Trust perform during the six months ending October 31, 2007?
A: For the six months ended October 31, 2007, Pioneer Municipal High Income
Trust earned a total return of -1.54% at net asset value and -0.11% at
market price. As of October 31, 2007, the Trust was selling at a discount
of market price to net asset value of 4.7%. The Lehman Brothers Municipal
Bond Index, which tracks the performance of investment-grade bonds,
returned 1.30% for the six months ended October 31, 2007. The Lehman
Brothers High Yield Municipal Bond Index returned -1.11% for the same
period. While the Trust invested in municipal securities with a broad range
of maturities and credit ratings, it maintained a dollar-weighted average
portfolio credit quality of BBB+ at October 31, 2007. At the end of the six
month period, the Trust held 116 issues in 36 states, territories, and the
District of Columbia. On October 31, 2007, the Trust's current yield was
5.75%, and its 30-day SEC yield based on market price was 7.31%.
Call 1-800-225-6292 or visit www.pioneerinvestments.com for the most recent
month-end performance results. Current performance may be lower or higher
than the performance data quoted.
The performance data quoted represents past performance, which is no
guarantee of future results. Investment return and principal value will
fluctuate, and shares, when redeemed, may be worth more or less than their
original cost.
Q: What was the investment environment like during the six months ended
October 31, 2007?
A: The investment environment changed dramatically during the six-month
period.
4
Pioneer Municipal High Income Trust
--------------------------------------------------------------------------------
--------------------------------------------------------------------------------
Early in the period, municipal bonds performed well against a backdrop of
moderating economic growth and relatively low interest rates. In July and
August, it became apparent that the problems in the subprime mortgage
market were worsening. As more and more homeowners defaulted on their
mortgages, investors sold the lower quality securities that were backed by
those mortgages. The sell-off in mortgage securities had a ripple effect
throughout the fixed-income markets, as investors gravitated toward the
safety of the Treasury market and abandoned other types of debt securities,
including municipal bonds.
As most fixed-income assets fell out of favor, concerns about a credit
crunch arose, causing an abrupt shift in Federal Reserve monetary policy.
Instead of emphasizing inflation risk, the central bank began to focus on
the potential for an economic slowdown. In September 2007, the Fed trimmed
two key interest rates by half a percentage point - the discount rate,
which is the rate the Fed charges member banks for loans, and the Fed funds
rate, the rate banks charge each other for overnight loans. In October
2007, the Fed took interest rates down another one-quarter percentage
point. At the end of the period, the Fed funds rate was 4.50%. These
actions had a stabilizing effect on the debt markets, and prices of
fixed-income investments began to recover from what we believe were
oversold conditions.
Q: What strategies did you use in managing the Trust?
A: Because none of the Trust's holdings had credit problems, we made no
substantive changes to the portfolio during the period. At the end of the
six months, 42.1% of the Trust's total investments were in investment grade
securities, 57.8% were in below investment grade securities and 0.1% were
in cash equivalents. The Trust remained fully invested throughout the
six-month period, and investments were diversified among several economic
sectors that underpin the U.S. economy. Investments in health care,
transportation and tobacco bonds accounted for the biggest positions. On
October 31, 2007, approximately 13% of the Trust's net assets were invested
in insured bonds whose interest and principal are insured by private
companies.

Pioneer Municipal High Income Trust
--------------------------------------------------------------------------------
PORTFOLIO MANAGEMENT DISCUSSION 10/31/07 (continued)
--------------------------------------------------------------------------------
On October 31, 2007, 23% of the Trust was leveraged. Our leveraging
strategy has aided returns for several years. Should rates decline, the
cost of borrowing would also go down, providing the Trust with a modest
amount of additional income. A rise in short-term interest rates in the
future would add to the Trust's borrowing costs, and the ability to sustain
present dividend levels could be affected.
Q: What influenced performance during the six months ended October 31, 2007?
A: During the turbulence of July and August, investors unwound their positions
in the riskiest assets. As a result, high-yield bonds were the worst
performing area of the market; and the Trust's high-yield holdings had a
negative impact on performance. The poor showing of the Trust's high-yield
securities was not related to credit problems or concerns of default. It
resulted from the general decline in the fixed-income markets, particularly
of lower-quality assets. The investment-grade component of the Trust aided
results, as it did not sell off as much as the high-yield position.
Q: What is your outlook over the next six months?
A: We plan to maintain our buy-and-hold strategy and keep the Trust fully
invested in a variety of economic sectors. We believe this strategy should
be beneficial, as we expect the pace of economic growth to continue to
moderate. The Federal Reserve has already reduced interest rates. Lower
rates should be positive for the Trust, as they have the potential for
boosting the value of the securities in the portfolio.
Investments in high-yield or lower-rated securities are subject to
greater-than-average risk. The Trust may invest in securities of issuers that
are in default or that are in bankruptcy.
A portion of income may be subject to state, federal, and/or alternative minimum
tax. Capital gains, if any, are subject to a capital gains tax. When interest
rates rise, the prices of fixed-income securities held by the Trust will
generally fall. Conversely, when interest rates fall the prices of fixed-income
securities held by the Trust will generally rise. By concentrating in municipal
securities, the Trust is more susceptible to adverse economic, political or
regulatory developments than is a portfolio that invests more broadly.
Investments in the Trust are subject to possible loss due to the financial
failure of underlying securities and their inability to meet their debt
obligations.
6
Pioneer Municipal High Income Trust
--------------------------------------------------------------------------------
--------------------------------------------------------------------------------
The Trust may use leverage through the issuance of preferred shares with an
aggregate liquidation preference of up to 25% of the Trust's total assets after
such issuance. Leverage creates significant risks, including the risk that the
Trust's income or capital appreciation will not be sufficient to cover the cost
of leverage, which may adversely affect the return for the holders of common
shares.
Risks of investing in the Trust are discussed in greater detail in the Trust's
registration statement on Form N-2 relating to its common shares.

Call 1-800-225-6292 or visit www.pioneerinvestments.com for the most recent
month-end performance results. Current performance may be lower or higher
than the performance data quoted.
Performance data shown represents past performance. Past performance is no
guarantee of future results. Investment return and market price will
fluctuate, and your shares may trade below net asset value ("NAV"), due to
such factors as interest rate changes, and the perceived credit quality of
borrowers.
Total investment return does not reflect broker sales charges or
commissions. All performance is for common shares of the Trust.
Closed-end funds, unlike open-end funds, are not continuously offered.
There is a one-time public offering and once issued, shares of closed-end
funds are sold in the open market through a stock exchange and frequently
trade at prices lower than their NAV. NAV is total assets less total
liabilities, which includes preferred shares, divided by the number of
common shares outstanding.
When NAV is lower than market price, dividends are assumed to be reinvested
at the greater of NAV or 95% of the market price. When NAV is higher,
dividends are assumed to be reinvested at prices obtained under the Trust's
dividend reinvestment plan.
The performance table and graph do not reflect the deduction of fees and
taxes that a shareowner would pay on Trust distributions or the redemption
of Trust shares.
The Lehman Brothers Municipal Bond Index is a broad measure of the
municipal bond market. Lehman Brothers Non-Investment Grade Municipal Bond
Index totals over $26 billion in market value and maintains over 1300
securities. Municipal bonds in this index have the following requirements:
maturities of one year or greater, sub investment grade (below Baa or
non-rated), fixed coupon rate, issued after 12/31/90, deal size over $20
million, maturity size of at least $3 million. Index returns are calculated
monthly, assume reinvestment of dividends and, unlike Trust returns, do not
reflect any fees, expenses or sales charges. You cannot invest directly in
the Indices.

1. Organization and Significant Accounting Policies
Pioneer Municipal High Income Trust (the "Trust") was organized as a Delaware
statutory trust on March 13, 2003. Prior to commencing operations on July 21,
2003, the Trust had no operations other than matters relating to its
organization and registration as a diversified, closed-end management
investment company under the Investment Company Act of 1940, as amended. The
Trust's primary investment objective is to provide its common shareholders with
a high level of current income exempt from regular federal income tax. As a
secondary investment objective, the Trust also may seek capital appreciation to
the extent consistent with its primary investment objective.
The Trust may invest in both investment and below investment grade (high-yield)
municipal securities with a broad range of maturities and credit ratings. Debt
securities rated below investment grade are commonly referred to as "junk
bonds" and are considered speculative. These securities involve greater risk of
loss, are subject to greater price volatility, and are less liquid, especially
during periods of economic uncertainty or change, than higher rated debt
securities.
Information regarding the Trust's principal risks is contained in the Trust's
original offering prospectus with additional information included in the
Trust's shareowner reports. Please refer to those documents when considering
the Trust's investment risks. At times, the Trust's investments may represent
industries or industry sectors that are interrelated or have common risks,
making it more susceptible to any economic, political, or regulatory
developments or other risks affecting those industries and sectors.
The Trust's financial statements have been prepared in conformity with U.S.
generally accepted accounting principles that require the management of the
Trust to, among other things, make estimates and assumptions that affect the
reported amounts of assets and liabilities, and the reported amounts of income,
expenses and gains and losses on investments during the reporting year. Actual
results could differ from those estimates.
26
Pioneer Municipal High Income Trust
--------------------------------------------------------------------------------
--------------------------------------------------------------------------------
The following is a summary of significant accounting policies followed by the
Trust in the preparation of its financial statements, which are consistent with
those policies generally accepted in the investment company industry:
A. Security Valuation
Security transactions are recorded as of trade date. Securities are valued
at prices supplied by independent pricing services, which consider such
factors as Treasury spreads, yields, maturities and ratings. Valuations may
be supplemented by values obtained from dealers and other sources, as
required. The values of interest rate swaps are determined by obtaining
dealer quotations. Securities for which market quotations are not readily
available are valued at their fair values as determined by, or under the
direction of, the Board of Trustees. At October 31, 2007 there were no
securities fair valued. Temporary cash investments are valued at net asset
value.
Dividend income is recorded on the ex-dividend date, except that certain
dividends from foreign securities where the ex-dividend date may have
passed are recorded as soon as the Trust becomes aware of the ex-dividend
data in the exercise of reasonable diligence. Discount and premium on debt
securities are accreted or amortized, respectively, daily on an effective
yield to maturity basis and are included in interest income. Interest
income, including interest bearing cash accounts, is recorded on an accrual
basis.
Gains and losses on sales of investments are calculated on the identified
cost method for both financial reporting and federal income tax purposes.
B. Federal Income Taxes
It is the Trust's policy to comply with the requirements of the Internal
Revenue Code applicable to regulated investment companies and to distribute
all of its taxable income and net realized capital gains, if any, to its
shareowners. Therefore, no federal income tax provision is required.
The amounts and characterizations of distributions to shareowners for
financial reporting purposes are determined in accordance with federal
income tax rules. Therefore, the source of the Trust's distributions may be
shown in the accompanying financial statements as either from or in excess
of net investment income or net
27

--------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 10/31/07 (unaudited) (continued)
--------------------------------------------------------------------------------
realized gain on investment transactions, or from paid in-capital,
depending on the type of book/tax differences that may exist.
At April 30, 2007, the Trust had a capital loss carryforward of $13,845,627
which is comprised of $9,706,870 which will expire in 2014 and $4,138,757
which will expire in 2015, if not utilized.
The tax character of current year distributions paid to common and
preferred shareowners will be determined at the end of the fiscal year. The
distributions during the year ended April 30, 2007 was as follows:
--------------------------------------------------------------------------------
2007
--------------------------------------------------------------------------------
Distributions paid from:
Tax exempt income $20,032,010
Ordinary income 480,476
-----------
Total $20,512,486
===========
--------------------------------------------------------------------------------
The following shows the components of distributable earnings on a federal
income tax basis at April 30, 2007.
--------------------------------------------------------------------------------
Undistributed tax-exempt income $ 682,501
Undistributed ordinary income 192,444
Capital loss carryforward (13,845,627)
Dividend payable (58,545)
Unrealized appreciation 52,353,009
-----------
Total $39,323,782
===========
--------------------------------------------------------------------------------
The difference between book-basis and tax-basis unrealized appreciation is
primarily attributable to the difference between book and tax amortization
methods for premiums and discounts on fixed income securities, the accrual
of income on securities in default and the difference between book and tax
accounting for swap agreements.
C. Automatic Dividend Reinvestment Plan
All common shareowners automatically participate in the Automatic Dividend
Reinvestment Plan (the "Plan"), under which participants receive all
dividends and capital gain distributions (collectively,
28
Pioneer Municipal High Income Trust
--------------------------------------------------------------------------------
--------------------------------------------------------------------------------
"dividends") in full and fractional common shares of the Trust in lieu of
cash. Shareowners may elect not to participate in the Plan. Shareowners not
participating in the Plan receive all dividends and capital gain
distributions in cash. Participation in the Plan is completely voluntary
and may be terminated or resumed at any time without penalty by notifying
American Stock Transfer & Trust Company, the agent for shareowners in
administering the Plan (the "Plan Agent"), in writing prior to any dividend
record date; otherwise such termination or resumption will be effective
with respect to any subsequently declared dividend or other distribution.
Whenever the Trust declares a dividend on common shares payable in cash,
participants in the Plan will receive the equivalent in common shares
acquired by the Plan Agent either (i) through receipt of additional
unissued but authorized common shares from the Trust or (ii) by purchase of
outstanding common shares on the New York Stock Exchange or elsewhere. If,
on the payment date for any dividend the net asset value per common share
is equal to or less than the market price per share plus estimated
brokerage trading fees ("market premium"), the Plan Agent will invest the
dividend amount in newly issued common shares. The number of newly issued
common shares to be credited to each account will be determined by dividing
the dollar amount of the dividend by the net asset value per common share
on the date the shares are issued, provided that the maximum discount from
the then current market price per share on the date of issuance does not
exceed 5%. If, on the payment date for any dividend, the net asset value
per common share is greater than the market value ("market discount"), the
Plan Agent will invest the dividend amount in common shares acquired in
open-market purchases. There are no brokerage charges with respect to newly
issued common shares. However, each participant will pay a pro rata share
of brokerage trading fees incurred with respect to the Plan Agent's
open-market purchases. Participating in the Plan does not relieve
shareowners from any federal, state or local taxes which may be due on
dividends paid in any taxable year. Shareowners holding Plan shares in a
brokerage account may not be able to transfer the shares to another broker
and continue to participate in the Plan.

--------------------------------------------------------------------------------
2. Management Agreement
Pioneer Investment Management, Inc. ("PIM"), a wholly owned indirect subsidiary
of UniCredito Italiano S.p.A. ("UniCredito Italiano"), manages the Trust's
portfolio. Management fees payable under the Trust's Advisory Agreement with
PIM are calculated daily at the annual rate of 0.60% of the Trust's average
daily managed assets. "Managed assets" is the average daily value of the
Trust's total assets minus the sum of the Trust's liabilities, which
liabilities exclude debt related to leverage, short-term debt and the aggregate
liquidation preference of any outstanding preferred shares. For the six months
ended October 31, 2007, the net management fee was equivalent to 0.60% of the
Trust's average daily managed assets, which was equivalent to 0.78% of the
Trust's average daily net assets attributable to the common shareowners.
In addition, under PIM's management and administration agreements, certain
other services and costs are paid by PIM and reimbursed by the Trust. At
October 31, 2007, $230,988 was payable to PIM related to management costs,
administrative costs and certain other services and is included in "Due to
affiliate" on the Statement of Assets and Liabilities.
The Trust has retained Princeton Administrators, LLC ("Princeton") to provide
certain administrative services to the Trust on its behalf. The Trust pays
Princeton a monthly fee at an annual rate of 0.07% of the average daily value
of the Trust's managed assets up to $500 million and 0.03% for average daily
managed assets in excess of $500 million, subject to a minimum monthly fee of
$10,000.
3. Transfer Agents
Pioneer Investment Management Shareholder Services, Inc. ("PIMSS"), a wholly
owned indirect subsidiary of UniCredito Italiano, through a sub-transfer agency
agreement with American Stock Transfer & Trust Company provides substantially
all transfer agent and shareowner services related to the Trust's common shares
at negotiated rates. Deutsche Bank Trust Company Americas ("Deutsche Bank") is
the transfer agent, registrar, dividend paying agent and redemption agent with
respect to the Trust's Auction Preferred Shares ("APS"). The Trust pays
Deutsche Bank an annual fee, as is agreed to from time to time by the Trust and
Deutsche Bank, for providing such services.
30
Pioneer Municipal High Income Trust
--------------------------------------------------------------------------------
--------------------------------------------------------------------------------
4. Interest Rate Swaps
The Trust may enter into interest rate swap transactions to attempt to protect
itself from increasing dividend or interest expense on its leverage resulting
from increasing short-term interest rates. The cost of leverage may rise with
an increase in interest rates, generally having the effect of lower yields and
potentially lower dividends to common shareowners. Interest rate swaps can be
used to "lock in" the cost of leverage and reduce the negative impact that
rising short-term interest rates would have on the Trust's leveraging costs.
An interest rate swap is an agreement between two parties, which involves
exchanging a floating rate and fixed rate interest payments for a specified
period of time. Interest rate swaps involve the accrual of the net interest
payments between the parties on a daily basis, with the net amount recorded
within the unrealized appreciation/depreciation of interest rate swaps on the
Statement of Assets and Liabilities. Once the interim payments are settled in
cash, at the pre-determined dates specified in the agreement, the net amount is
recorded as realized gain or loss from interest rate swaps on the Statement of
Operations. During the term of the swap, changes in the value of the swap are
recognized as unrealized gains and losses by "marking-to-market" the value of
the swap based on values obtained from dealer quotations. When the swap is
terminated, the Trust will record a realized gain or loss equal to the
difference, if any, between the proceeds from (or cost of) closing the contract
and the cost basis of the contract. The Trust is exposed to credit risk in the
event of non-performance by the other party to the interest rate swap. However,
at October 31, 2007, the Trust does not anticipate non-performance by any
counterparty. Risk may also arise with regard to market movements in the value
of the swap arrangement that do not exactly offset the changes in the related
dividend requirement or interest expense on the Trust's leverage.

NOTES TO FINANCIAL STATEMENTS 10/31/07 (unaudited) (continued)
--------------------------------------------------------------------------------
Under the terms of the agreement entered into by the Trust, the Trust receives
a floating rate of interest and pays a fixed rate of interest for the term.
Details of the swap agreement outstanding as of October 31, 2007 were as
follows:
-------------------------------------------------------------------------------------------
Notional

UBS AG April 5, 2009 $50,000 2.665% 1 month BMA $366,695
-------------------------------------------------------------------------------------------
5. Trust Shares
There are an unlimited number of common shares of beneficial interest
authorized. Of the 22,120,893 common shares of beneficial interest outstanding
at October 31, 2007, PIM owned 6,981 shares.
During the six months ended October 31, 2007 and the year ended April 30, 2007,
there were no share transactions by the Trust. All reinvested distributions
were satisfied with previously issued shares purchased in the open market by
the Plan Agent and credited to shareowner accounts.
The Trust may classify or reclassify any unissued common shares of beneficial
interest into one or more series of preferred shares of beneficial interest. As
of October 31, 2007, there were 4,040 APS as follows: Series A-2,000 and Series
B-2,040.
Dividends on Series A and Series B are cumulative at a rate which is reset
every seven days based on the results of an auction. Dividend rates ranged from
3.19% to 4.10% during the six months ended October 31, 2007.
The Trust may not declare dividends or make other distributions on its common
shares or purchase any such shares if, at the time of the declaration,
distribution or purchase, asset coverage with respect to the outstanding
preferred shares would be less than 200%.
The APS are redeemable at the option of the Trust, in whole or in part, on any
dividend payment date at $25,000 per share plus any accumulated or unpaid
dividends, whether or not declared. The APS are also subject to mandatory
redemption at $25,000 per share plus any accumulated or unpaid dividends,
whether or not declared, if certain requirements relating to the composition of
the assets and liabilities of the Trust as set forth in the Agreement and
Declaration of Trust are not satisfied.
32
Pioneer Municipal High Income Trust
--------------------------------------------------------------------------------
--------------------------------------------------------------------------------
The holders of APS have voting rights equal to the holders of the Trust's
common shares (one vote per share) and will vote together with holders of the
common shares as a single class. However, holders of APS are also entitled to
elect two of the Trust's Trustees. In addition, the Investment Company Act of
1940, as amended, requires that along with approval by shareowners that might
otherwise be required, the approval of the holders of a majority of any
outstanding preferred shares, voting separately as a class, would be required
to (a) adopt any plan of reorganization that would adversely affect the
preferred shares and (b) take any action requiring a vote of security holders,
including, among other things, changes in the Trust's subclassification as a
closed-end management investment company or changes in its fundamental
investment restrictions.
6. New Pronouncements
In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements ("SFAS 157"), was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. At this time, management is currently evaluating the impactions
of SFAS 157 and its impact on the Trust's financial statement disclosures, if
any, has not yet been determined.
7. Subsequent Events
Subsequent to October 31, 2007, the Board of Trustees of the Trust declared a
dividend from undistributed net investment income of $0.07 per common share
payable November 30, 2007, to shareowners of record on November 15, 2007.
Subsequent to October 31, 2007, dividends declared and paid on preferred shares
totaled $297,310 in aggregate for the two outstanding preferred share series
through December 6, 2007.

PIONEER FUNDS
APPROVAL OF AUDIT, AUDIT-RELATED, TAX AND OTHER SERVICES
PROVIDED BY THE INDEPENDENT AUDITOR
SECTION I - POLICY PURPOSE AND APPLICABILITY
The Pioneer Funds recognize the importance of maintaining the independence of
their outside auditors. Maintaining independence is a shared responsibility
involving Pioneer Investment Management, Inc ("PIM"), the audit committee and
the independent auditors.
The Funds recognize that a Fund's independent auditors: 1) possess knowledge of
the Funds, 2) are able to incorporate certain services into the scope of the
audit, thereby avoiding redundant work, cost and disruption of Fund personnel
and processes, and 3) have expertise that has value to the Funds. As a result,
there are situations where it is desirable to use the Fund's independent
auditors for services in addition to the annual audit and where the potential
for conflicts of interests are minimal. Consequently, this policy, which is
intended to comply with Rule 210.2-01(C)(7), sets forth guidelines and
procedures to be followed by the Funds when retaining the independent audit firm
to perform audit, audit-related tax and other services under those
circumstances, while also maintaining independence.
Approval of a service in accordance with this policy for a Fund shall also
constitute approval for any other Fund whose pre-approval is required pursuant
to Rule 210.2-01(c)(7)(ii).
In addition to the procedures set forth in this policy, any non-audit services
that may be provided consistently with Rule 210.2-01 may be approved by the
Audit Committee itself and any pre-approval that may be waived in accordance
with Rule 210.2-01(c)(7)(i)(C) is hereby waived.
Selection of a Fund's independent auditors and their compensation shall be
determined by the Audit Committee and shall not be subject to this policy.
