Pioneer Municipal High Income Advantage Trust | Semiannual Report | 9/30/10    1



President's Letter

Dear Shareowner,

Through the first nine months of 2010, the U.S. economy moved forward on a slow
path to recovery. But with the memory of a deep recession still lingering,
businesses and consumers remained cautious about both investing and spending.
While business fundamentals showed signs of improvement, there was still a
reluctance to hire, and high unemployment remains a problem. Wary investors,
concerned about risk, gravitated towards cash and bonds. We remain generally
optimistic about the prospects for economic recovery, although it may occur more
slowly than many would like.

At Pioneer, we have long advocated the benefits of staying diversified and
investing for the long term. This strategy has generally performed well for many
investors. Bond markets certainly rewarded investors in the first nine months of
2010. While the equity markets barely budged, equities at the end of September
2010 were inexpensive relative to bonds, compared with historic levels, and
represented potentially good value for long-term investors.

Pioneer has not changed the basic approach to investing that we have used for
more than 80 years. We remain focused on company fundamentals and risk
management. Our investment process is based on careful research into individual
companies, quantitative analysis, and active portfolio management. This
three-pillared process, which we apply to each of our portfolios, is supported
by an integrated team approach and is designed to carefully balance risk and
reward. Our experienced professionals devote themselves to the careful research
needed to identify investment opportunities in markets around the world.

Our advice, as always, is to work closely with a trusted financial advisor to
discuss your goals and work together to develop an investment strategy that
meets your individual needs. There is no single best strategy that works for
every investor.

We invite you to learn more about Pioneer and our time-tested approach to
investing by consulting with your financial advisor or visiting us online at

you for investing with Pioneer.

Sincerely,


/s/ Daniel K. Kingsbury

Portfolio Management Discussion | 9/30/10

In the following interview, David Eurkus, who is responsible for the daily
management of Pioneer Municipal High Income Advantage Trust, discusses some of
the factors that affected the municipal bond market and the Trust over the
six-month period ended September 30, 2010.

Q  How did the Trust perform over the six months ended September 30, 2010?

A  For the six-month period ended September 30, 2010, Pioneer Municipal High
   Income Advantage Trust produced a total return of 10.73% at net asset value
   and 11.88% at market price, and the Trust's shares were selling at an 8.1%
   premium of market price to net asset value on September 30, 2010. Over the
   same six-month period, the Trust's benchmarks, the Barclays Capital Municipal
   Bond Index, which tracks the performance of investment-grade bonds, returned
   5.51%; and the Barclays Capital High Yield Municipal Bond Index returned
   7.78%. Unlike the Trust, the two Barclays Capital indices are not leveraged.
   On September 30, 2010, the Trust held 151 issues in 36 states, territories
   and the District of Columbia.

   The Trust's 30-day SEC yield was 8.07% on September 30, 2010, and its
   taxable equivalent yield was 11.80%, based on the maximum Federal income
   tax rate of 35%. As of September 30, 2010, roughly 19% of the Trust's
   investments were subject to the Federal Alternative Minimum Tax (AMT).

Q  What was the investment environment like during the six-month period ended
   September 30, 2010?

A  The investment environment for both the municipal bond market and the Trust
   was positive over the six months ended September 30, 2010, as market interest
   rates continued to decline. In a slow-growing economy, inflation remained
   subdued and the Federal Reserve Board (the Fed) maintained an accommodative
   monetary policy designed to stimulate economic growth. Against that backdrop,
   demand for municipal securities was robust, as traditional and
   non-traditional buyers came into the market.

Q  How did you position the Trust in that environment over the six months ended
   September 30, 2010, and what factors most affected the Trust's performance
   during the period?

A  We did not make any significant changes to the Trust's portfolio over the six
   months ended September 30, 2010. More than a year ago, we had positioned the
   Trust's portfolio in an effort to take advantage of market areas that had


4    Pioneer Municipal High Income Advantage Trust | Semiannual Report | 9/30/10


   become oversold in the financial crisis. We were particularly drawn to
   sectors that typically support the U.S. economy, and that approach benefited
   the Trust. Over the six months ended September 30, 2010, the Trust remained
   fully invested and diversified.

   At September 30, 2010, 57.8% of the Trust's total investment portfolio was
   invested in investment-grade bonds, and 39.9% of the Trust's total investment
   portfolio was invested in below investment-grade bonds. The Trust also had a
   2.3% cash position.

   In general, the higher-rated bonds in the Trust's portfolio underperformed
   the lower-rated securities. While most of the Trust's holdings did well,
   there were some that fell short of our expectations. Examples are: California
   Statewide Environmental Facility; and two positions (one in California and
   one in Texas) in Microgy Holdings Alternative Energy Facility. Those
   positions declined in value, and have been liquidated from the Trust.

   As of September 30, 2010, health care (35.6% of the Trust's total investment
   portfolio) was the Trust's biggest position, followed by transportation
   (13.8% of the Trust's total investment portfolio), tobacco (11.0% of the
   Trust's total investment portfolio) and pollution control (6.5% of the
   Trust's total investment portfolio). The Trust also held bonds in the
   housing, pollution control, power and water and sewer sectors. Most of the
   Trust's assets were held in revenue bonds. The payment of interest and
   principal on revenue bonds is covered by revenues generated from the
   particular asset the bond was issued to finance. For example, a bond issued
   to fund a continuing care retirement community is backed by the revenue that
   accrues from users of that facility.

Q  What is your outlook?

A  As we look ahead, we believe the environment for municipal bonds in which the
   Trust invests should continue to be positive. We expect economic growth to be
   slow, but steady, and believe that the Fed will keep interest rates at
   current levels into 2011. Personal income tax rates on higher-income earners
   may go up, depending on Congressional actions, and it appears possible that
   the Build America Bonds (BAB) program could be extended into 2011. BABs are
   taxable municipal debt instruments that are subsidized by the U.S. Treasury.
   Continued issuance of these bonds could dampen the supply of tax-exempt
   bonds. We believe all of those factors are likely to drive investment in
   municipal securities and should benefit the Trust. We believe municipal bonds
   in which the Trust invests should continue to provide investors with a
   relatively stable and competitive stream of income.


Please refer to the Schedule of Investments on pages 10-20 for a full listing
of Trust securities.


Pioneer Municipal High Income Advantage Trust | Semiannual Report | 9/30/10    5



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 in the Trust will generally
fall. Conversely, when interest rates fall, the prices of fixed-income
securities in the Trust will generally rise. By concentrating in municipal
securities, the portfolio 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 the issuers of the underlying securities and their inability to meet
their debt obligations.

The Trust uses leverage through the issuance of preferred shares. 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. Since February of
2008, regularly scheduled auctions for the Trust's preferred shares have failed
and preferred shareowners have not been able to sell their shares at auction.
The Board of Trustees of the Trust has considered, and continues to consider,
this issue.

The Trust is required to maintain certain regulatory and rating agency asset
coverage requirements in connection with its outstanding preferred shares. In
order to maintain required asset coverage levels, the Trust may be required to
alter the composition of its investment portfolio or take other actions, such as
redeeming preferred shares with the proceeds from portfolio transactions, at
what might be inopportune times in the market. Such actions could reduce the net
earnings or returns to holders of the Trust's common shares over time.

Risks of investing in the Trust are discussed in greater detail in the Trust's
original offering documents relating to its common shares and shareowner reports
issued from time to time.

Past performance is no guarantee of future results, and there is no guarantee
that market forecasts discussed will be realized.

Any information in this shareowner report regarding market or economic trends or
the factors influencing the Trust's historical or future performance are
statements of the opinion of Trust management as of the date of this report.
These statements should not be relied upon for any other purposes.

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 per common share 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 sale of Trust shares.

Index comparison begins October 31, 2003. The Barclays Capital Municipal Bond
Index is a broad measure of the municipal bond market. Barclays Capital High
Yield 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, issue date later than 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. The indices are not leveraged. You
cannot invest directly in the indices.

1. Organization and Significant Accounting Policies

Pioneer Municipal High Income Advantage Trust (the Trust) was organized as a
Delaware statutory trust on August 6, 2003. Prior to commencing operations on
October 20, 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 investment
objective of the Trust is to seek a high level of current income exempt from
regular federal income tax, and the Trust may seek capital appreciation to the
extent that it is consistent with its primary investment objective.

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. 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 from time to time. Please
refer to those documents when considering the Trust's risks.

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.

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, the disclosure of contingent assets
and liabilities at the date of the financial statements, and the reported
amounts of income, expenses and gain or loss on investments during the reporting
year. Actual results could differ from those estimates.

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. The net asset value of
   the Trust is computed once daily, on each day the New York Stock Exchange
   (NYSE) is open, as of the close of regular trading on the NYSE. Fixed


26   Pioneer Municipal High Income Advantage Trust | Semiannual Report | 9/30/10


   income securities with remaining maturity of more than sixty days are valued
   at prices supplied by independent pricing services, which consider such
   factors as market prices, market events, quotations from one or more brokers,
   Treasury spreads, yields, maturities and ratings. Valuations may be
   supplemented by dealers and other sources, as required. The values of
   interest rate swaps are determined by obtaining dealer quotations. Equity
   securities that have traded on an exchange are valued at the last sale price
   on the principal exchange where they are traded. Equity securities that have
   not traded on the date of valuation, or securities for which sale prices are
   not available, generally are valued using the mean between the last bid and
   asked prices. Securities for which independent pricing services are unable to
   supply prices or for which market prices and/or quotations are not readily
   available or are considered to be unreliable are valued using fair value
   methods pursuant to procedures adopted by the Board of Trustees.

   The Trust may use fair value methods if it is determined that a significant
   event has occurred after the close of the exchange or market on which the
   security trades and prior to the determination of the Trust's net asset
   value. Thus, the valuation of the Trust's securities may differ from exchange
   prices. At September 30, 2010, one security was valued using fair value
   methods (in addition to securities valued using prices supplied by
   independent pricing services) representing 0.00% of net assets. Inputs used
   when applying fair value methods to value a security may include credit
   ratings, the financial condition of the company, current market conditions
   and comparable securities. Short-term fixed income securities with remaining
   maturities of sixty days or less generally are valued at amortized cost.
   Money market mutual funds are valued at net asset value.

   Discount and premium on debt securities are accreted or amortized,
   respectively, daily into interest income on a yield-to-maturity basis with a
   corresponding increase or decrease in the cost basis of the security.
   Interest income, including interest-bearing cash accounts, is recorded on an
   accrual basis.

   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.

   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. Tax
   years for the prior three fiscal years remain subject to examination by tax
   authorities.

   The amounts and characterizations of distributions to shareowners for
   financial reporting purposes are determined in accordance with federal income
   tax rules. Therefore, the sources of the Trust's distributions may be shown
   in the accompanying financial statements as from or in excess of net
   investment income or net realized gain (loss) on investment transactions, or
   as from paid-in capital, depending on the type of book/tax differences that
   may exist.

   The tax character of current year distributions paid to common and preferred
   shareowners will be determined at the end of the fiscal year. Distributions
   paid during the year ended March 31, 2010 were as follows:




- ---------------------------------------------
                                         2010
- ---------------------------------------------
                               
Distributions paid from:
Tax exempt income                 $22,779,781
Ordinary income                        80,715
- ---------------------------------------------
  Total                           $22,860,496
=============================================



   The following shows the components of distributable earnings (losses) on a
   federal income tax basis at March 31, 2010:




- -----------------------------------------------------
                                                 2010
- -----------------------------------------------------
                                    
Distributable earnings:
Undistributed tax-exempt income        $   8,020,971
Undistributed ordinary income                 30,783
Capital loss carryforward                (50,523,623)
Post-October-loss deferred                (5,465,720)
Dividends payable                             (5,267)
Unrealized appreciation                    2,749,395
- -----------------------------------------------------
  Total                                $ (45,193,461)
=====================================================



   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 difference
   between book and tax accounting for swap agreements, book/tax difference in
   accrual of income on securities in default, and other temporary differences.

C. Automatic Dividend Reinvestment Plan

   All common shareowners whose shares are registered in their own names
   automatically participate in the Automatic Dividend Reinvestment Plan (the
   Plan), under which participants receive all dividends and capital gain
   distributions (collectively, 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.

   If a shareowner's shares are held in the name of a brokerage firm, bank or
   other nominee, the shareowner can ask the firm or nominee to participate in
   the Plan on the shareowner's behalf. If the firm or nominee does not offer
   the Plan, dividends will be paid in cash to the shareowner of record. A firm
   or nominee may reinvest a shareowner's cash dividend in common shares of the
   Trust on terms that differ from the terms of the Plan.

   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), the Trust's investment adviser, a
wholly owned indirect subsidiary of UniCredit S.p.A. (UniCredit), 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" means (a) the total assets of the Trust,
including any form of investment leverage, minus (b) all accrued liabilities
incurred in the normal course of operations, which shall not include any
liabilities or obligations attributable to investment leverage obtained through
(i) indebtedness of any type (including, without limitation, borrowing through a
credit facility of the issuance of debt securities), (ii) the issuance of
preferred stock or other similar preference securities, and/or (iii) any other
means. For the six months ended September 30, 2010, the net management fee was
equivalent to 0.60% of the Trust's average daily managed assets, which was
equivalent to 0.95% 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 September 30,
2010, $231,878 was payable to PIM related to management costs, administrative
costs and certain other services and is included in "Due to affiliates" on the
Statement of Assets and Liabilities.

Effective September 1, 2010 PIM has retained State Street Bank and Trust Company
(State Street) to provide certain administrative and accounting services to the
Trust on its behalf. For administrative services, PIM pays State Street a
monthly fee at an annual rate of 0.07% of the Trust's managed assets up to $500
million and 0.03% for managed assets in excess of $500 million, subject to a
minimum monthly fee of $10,000. Previously, PIM had retained Princeton
Administrators, LLC (Princeton) to provide such services. PIM paid Princeton a
monthly fee at an annual rate of 0.07% of the Trust's average daily 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. Neither State
Street nor Princeton received compensation directly from the Trust for providing
such services.


3. Transfer Agents

Pioneer Investment Management Shareholder Services, Inc. (PIMSS), a wholly owned
indirect subsidiary of UniCredit, 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 auction agent with respect to the
Trust's Auction Preferred Shares (APS). The Trust pays Deutsche


30   Pioneer Municipal High Income Advantage Trust | Semiannual Report | 9/30/10



Bank an annual fee, as is agreed to from time to time by the Trust and Deutsche
Bank, for providing such services.


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 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. 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.

There were no interest rate swap contracts outstanding at September 30, 2010.


5. Trust Shares

There are an unlimited number of common shares of beneficial interest
authorized.

Transactions in common shares of beneficial interest for the six months ended
September 30, 2010 and the year ended March 31, 2010 were as follows:




- -------------------------------------------------------------------------
                                                     9/10            3/10
- -------------------------------------------------------------------------
                                                         
 Shares outstanding at beginning of period     22,995,047      22,879,496
 Reinvestment of distributions                     54,902         115,551
- -------------------------------------------------------------------------
 Shares outstanding at end of period           23,049,949      22,995,047
=========================================================================


Pioneer Municipal High Income Advantage Trust | Semiannual Report | 9/30/10   31



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 September 30, 2010, there were 6,000 APS as follows: Series A -- 3,000 and
Series B -- 3,000.

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. An auction fails if there
are more APS offered for sale than there are buyers. When an auction fails, the
dividend rate for the period will be the maximum rate on the auction dates
described in the prospectus for the APS. Preferred shareowners will not be able
to sell their APS at an auction if the auction fails. Since February 2008, the
Trust's auctions related to the APS have failed. The maximum rate for the 7-Day
Series is 125% of the 7 day commercial paper rate or adjusted Kenny rate.
Dividend rates on APS ranged from 0.398% to 0.571% during the six months ended
September 30, 2010.

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, the Trust does not comply with the asset coverage
ratios described in the prospectus for the APS.

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 Statement of
Preferences are not satisfied.

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. 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. Subsequent Events

Subsequent to September 30, 2010 the Board of Trustees of the Trust declared a
dividend from undistributed net investment income of $0.090 per common share
payable October 29, 2010, to common shareowners of record on October 15, 2010.


32   Pioneer Municipal High Income Advantage Trust | Semiannual Report | 9/30/10



Subsequent to September 30, 2010, dividends declared and paid on preferred
shares totaled $108,810 in aggregate for the two outstanding preferred share
series through November 24, 2010.

In preparing these financial statements, PIM has evaluated the impact of all
events and transactions for potential recognition or disclosure and has
determined that other than disclosed above, there were no subsequent events
requiring recognition or disclosure in the financial statements.

            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.

                 not performed by the Audit
                 firm, the scope of the Audit
                 Services would likely
                 increase.  The Services are

                 professional standards (AICPA,

shareholders, on the one hand, and those of the company's investment adviser;
principal underwriter; or any affiliated person (as defined in Section 2(a)(3)
of the Investment Company Act of 1940 (15 U.S.C. 80a-2(a)(3)) and the rules
thereunder) of the company, its investment adviser, or its principal
underwriter, on the other. Include any policies and procedures of the company's

		    Proxy Voting Policies and Procedures of
                       Pioneer Investment Management, Inc.

                            VERSION DATED July, 2004

                                    Overview

   Pioneer Investment Management, Inc. ("Pioneer") is a fiduciary that owes
   each of its client's duties of care and loyalty with respect to all
   services undertaken on the client's behalf, including proxy voting. When
   Pioneer has been delegated proxy-voting authority for a client, the duty of
   care requires Pioneer to monitor corporate events and to vote the proxies.
   To satisfy its duty of loyalty, Pioneer must place its client's interests
   ahead of its own and must cast proxy votes in a manner consistent with the
   best interest of its clients. Pioneer will vote all proxies presented in a
   timely manner.

   The Proxy Voting Policies and Procedures are designed to complement
   Pioneer's investment policies and procedures regarding its general
   responsibility to monitor the performance and/or corporate events of
   companies that are issuers of securities held in accounts managed by
   Pioneer. Pioneer's Proxy Voting Policies summarize Pioneer's position on a
   number of issues solicited by companies held by Pioneer's clients. The
   policies are guidelines that provide a general indication on how Pioneer
   would vote but do not include all potential voting scenarios.

   Pioneer's Proxy Voting Procedures detail monitoring of voting, exception
   votes, and review of conflicts of interest and ensure that case-by-case
   votes are handled within the context of the overall guidelines (i.e. best
   interest of client). The overriding goal is that all proxies for US and
   non-US companies that are received promptly will be voted in accordance
   with Pioneer's policies or specific client instructions. All shares in a
   company held by Pioneer-managed accounts will be voted alike, unless a
   client has given us specific voting instructions on an issue or has not
   delegated authority to us or the Proxy Voting Oversight Group determines
   that the circumstances justify a different approach.

   Pioneer does not delegate the authority to vote proxies relating to its
   clients to any of its affiliates, which include other subsidiaries of
   UniCredito.

   Any questions about these policies and procedures should be directed to the
   Proxy Coordinator.

                             Proxy Voting Procedures

   Proxy Voting Service
   Pioneer has engaged an independent proxy voting service to assist in the
   voting of proxies. The proxy voting service works with custodians to ensure
   that all proxy materials are received by the custodians and are processed
   in a timely fashion. To the extent applicable, the proxy voting service
   votes all proxies in accordance with the proxy voting policies established
   by Pioneer. The proxy voting service will refer proxy questions to the
   Proxy Coordinator (described below) for instructions under circumstances
   where: (1) the application of the proxy voting guidelines is unclear; (2) a
   particular proxy question is not covered by the guidelines; or (3) the
   guidelines call for specific instructions on a case-by-case basis. The
   proxy voting service is also requested to call to the Proxy Coordinator's
   attention specific proxy questions that, while governed by a guideline,
   appear to involve unusual or controversial issues. Pioneer reserves the
   right to attend a meeting in person and may do so when it determines that
   the company or the matters to be voted on at the meeting are strategically
   important to its clients.

   Proxy Coordinator
   Pioneer's Director of Investment Operations (the "Proxy Coordinator")
   coordinates the voting, procedures and reporting of proxies on behalf of
   Pioneer's clients. The Proxy Coordinator will deal directly with the proxy
   voting service and, in the case of proxy questions referred by the proxy
   voting service, will solicit voting recommendations and instructions from
   the Director of Portfolio Management US or, to the extent applicable,
   investment sub-advisers. The Proxy Coordinator is responsible for ensuring
   that these questions and referrals are responded to in a timely fashion and
   for transmitting appropriate voting instructions to the proxy voting
   service. The Proxy Coordinator is responsible for verifying with the
   Compliance Department whether Pioneer's voting power is subject to any
   limitations or guidelines issued by the client (or in the case of an
   employee benefit plan, the plan's trustee or other fiduciaries).

   Referral Items
   From time to time, the proxy voting service will refer proxy questions to
   the Proxy Coordinator that are described by Pioneer's policy as to be voted
   on a case-by-case basis, that are not covered by Pioneer's guidelines or
   where Pioneer's guidelines may be unclear with respect to the matter to be
   voted on. Under such certain circumstances, the Proxy Coordinator will seek
   a written voting recommendation from the Director of Portfolio Management
   US. Any such recommendation will include: (i) the manner in which the
   proxies should be voted; (ii) the rationale underlying any such decision;
   and (iii) the disclosure of any contacts or communications made between
   Pioneer and any outside parties concerning the proxy proposal prior to the
   time that the voting instructions are provided. In addition, the Proxy
   Coordinator will ask the Compliance Department to review the question for
   any actual or apparent conflicts of interest as described below under
   "Conflicts of

                                       2


   Interest." The Compliance Department will provide a "Conflicts of Interest
   Report," applying the criteria set forth below under "Conflicts of
   Interest," to the Proxy Coordinator summarizing the results of its review.
   In the absence of a conflict of interest, the Proxy Coordinator will vote
   in accordance with the recommendation of the Director of Portfolio
   Management US.

   If the matter presents a conflict of interest for Pioneer, then the Proxy
   Coordinator will refer the matter to the Proxy Voting Oversight Group for a
   decision. In general, when a conflict of interest is present, Pioneer will
   vote according to the recommendation of the Director of Portfolio
   Management US where such recommendation would go against Pioneer's interest
   or where the conflict is deemed to be immaterial. Pioneer will vote
   according to the recommendation of its proxy voting service when the
   conflict is deemed to be material and the Pioneer's internal vote
   recommendation would favor Pioneer's interest, unless a client specifically
   requests Pioneer to do otherwise. When making the final determination as to
   how to vote a proxy, the Proxy Voting Oversight Group will review the
   report from the Director of Portfolio Management US and the Conflicts of
   Interest Report issued by the Compliance Department.

   Conflicts of Interest
   A conflict of interest occurs when Pioneer's interests interfere, or appear
   to interfere with the interests of Pioneer's clients. Occasionally, Pioneer
   may have a conflict that can affect how its votes proxies. The conflict may
   be actual or perceived and may exist when the matter to be voted on
   concerns:

       o      An affiliate of Pioneer,  such as another company  belonging to
              the UniCredito  Italiano  S.p.A.  banking group (a "UniCredito
              Affiliate");

       o      An issuer of a security for which Pioneer acts as a sponsor,
              advisor, manager, custodian, distributor, underwriter, broker, or
              other similar capacity (including those securities specifically
              declared by PGAM to present a conflict of interest for Pioneer);

       o      An issuer of a security for which UniCredito has informed Pioneer
              that a UniCredito Affiliate acts as a sponsor, advisor, manager,
              custodian, distributor, underwriter, broker, or other similar
              capacity; or

       o      A person with whom Pioneer (or any of its affiliates) has an
              existing, material contract or business relationship that was not
              entered into in the ordinary course of Pioneer's business.

       o      Pioneer will abstain from voting with respect to companies
              directly or indirectly owned by UniCredito Italiano Group, unless
              otherwise directed by a client. In addition, Pioneer will inform
              PGAM Global Compliance and the PGAM Independent Directors before
              exercising such rights.

   Any associate involved in the proxy voting process with knowledge of any
   apparent or actual conflict of interest must disclose such conflict to the
   Proxy Coordinator and the Compliance Department. The Compliance Department
   will review each item referred to Pioneer to determine whether an actual or
   potential conflict of interest with Pioneer exists in connection with the
   proposal(s) to be voted upon. The review will be conducted by comparing the
   apparent parties affected by the proxy proposal being

                                       3


   voted upon against the Compliance Department's internal list of interested
   persons and, for any matches found, evaluating the anticipated magnitude
   and possible probability of any conflict of interest being present. For
   each referral item, the determination regarding the presence or absence of
   any actual or potential conflict of interest will be documented in a
   Conflicts of Interest Report to the Proxy Coordinator.

   Securities Lending
   In conjunction with industry standards Proxies are not available to be
   voted when the shares are out on loan through either Pioneer's lending
   program or a client's managed security lending program. However, Pioneer
   will reserve the right to recall lent securities so that they may be voted
   according to the Pioneer's instructions. If a portfolio manager would like
   to vote a block of previously lent shares, the Proxy Coordinator will work
   with the portfolio manager and Investment Operations to recall the
   security, to the extent possible, to facilitate the vote on the entire
   block of shares.

   Share-Blocking

   "Share-blocking" is a market practice whereby shares are sent to a
   custodian (which may be different than the account custodian) for record
   keeping and voting at the general meeting. The shares are unavailable for
   sale or delivery until the end of the blocking period (typically the day
   after general meeting date).

   Pioneer will vote in those countries with "share-blocking." In the event a
   manager would like to sell a security with "share-blocking", the Proxy
   Coordinator will work with the Portfolio Manager and Investment Operations
   Department to recall the shares (as allowable within the market time-frame
   and practices) and/or communicate with executing brokerage firm. A list of
   countries with "share-blocking" is available from the Investment Operations
   Department upon request.

   Record Keeping
   The Proxy Coordinator shall ensure that Pioneer's proxy voting service:

       o   Retains a copy of the proxy statement received (unless the proxy
           statement is available from the SEC's Electronic Data Gathering,
           Analysis, and Retrieval (EDGAR) system);

       o   Retains a record of the vote cast;

       o   Prepares Form N-PX for filing on behalf of each client that is a
           registered investment company; and

       o   Is able to promptly provide Pioneer with a copy of the voting
           record upon its request.

                                       4


   The Proxy Coordinator shall ensure that for those votes that may require
   additional documentation (i.e. conflicts of interest, exception votes and
   case-by-case votes) the following records are maintained:

       o    A record memorializing the basis for each referral vote cast;

       o    A copy of any document created by Pioneer that was material in
            making the decision on how to vote the subject proxy; and

       o    A copy of any conflict notice, conflict consent or any other
            written communication (including emails or other electronic
            communications) to or from the client (or in the case of an
            employee benefit plan, the plan's trustee or other fiduciaries)
            regarding the subject proxy vote cast by, or the vote
            recommendation of, Pioneer.

       o    Pioneer shall maintain the above records in the client's file for a
            period not less than ten (10) years.

     Disclosure
     Pioneer shall take reasonable measures to inform its clients of the process
     or procedures clients must follow to obtain information regarding how
     Pioneer voted with respect to assets held in their accounts. In addition,
     Pioneer shall describe to clients its proxy voting policies and procedures
     and will furnish a copy of its proxy voting policies and procedures upon
     request. This information may be provided to clients through Pioneer's Form
     ADV (Part II) disclosure, by separate notice to the client, or through
     Pioneer's website.

     Proxy Voting Oversight Group
     The members of the Proxy Voting Oversight Group are Pioneer's: Director of
     Portfolio Management US, Head of Investment Operations, and Director of
     Compliance. Other members of Pioneer will be invited to attend meetings and
     otherwise participate as necessary. The Head of Investment Operations will
     chair the Proxy Voting Oversight Group.

     The Proxy Voting Oversight Group is responsible for developing, evaluating,
     and changing (when necessary) Pioneer's Proxy Voting Policies and
     Procedures. The group meets at least annually to evaluate and review these
     policies and procedures and the services of its third-party proxy voting
     service. In addition, the Proxy Voting Oversight Group will meet as
     necessary to vote on referral items and address other business as
     necessary.

     Amendments
     Pioneer may not amend its Proxy Voting Policies And Procedures without the
     prior approval of the Proxy Voting Oversight Group and its corporate
     parent, Pioneer Global Asset Management S.p.A

                                       5


   Proxy Voting Policies
   Pioneer's sole concern in voting proxies is the economic effect of the
   proposal on the value of portfolio holdings, considering both the short-
   and long-term impact. In many instances, Pioneer believes that supporting
   the company's strategy and voting "for" management's proposals builds
   portfolio value. In other cases, however, proposals set forth by management
   may have a negative effect on that value, while some shareholder proposals
   may hold the best prospects for enhancing it. Pioneer monitors developments
   in the proxy-voting arena and will revise this policy as needed.

   All proxies that are received promptly will be voted in accordance with the
   specific policies listed below. All shares in a company held by
   Pioneer-managed accounts will be voted alike, unless a client has given us
   specific voting instructions on an issue or has not delegated authority to
   us. Proxy voting issues will be reviewed by Pioneer's Proxy Voting
   Oversight Group, which consists of the Director of Portfolio Management US,
   the Director of Investment Operations (the Proxy Coordinator), and the
   Director of Compliance.

   Pioneer has established Proxy Voting Procedures for identifying and
   reviewing conflicts of interest that may arise in the voting of proxies.

   Clients may request, at any time, a report on proxy votes for securities
   held in their portfolios and Pioneer is happy to discuss our proxy votes
   with company management. Pioneer retains a proxy voting service to provide
   research on proxy issues and to process proxy votes.

Administrative
   While administrative items appear infrequently in U.S. issuer proxies, they
   are quite common in non-U.S. proxies.

   We will generally support these and similar management proposals:

       o    Corporate name change.

       o    A change of corporate headquarters.

       o    Stock exchange listing.

       o    Establishment of time and place of annual meeting.

       o    Adjournment or postponement of annual meeting.

       o    Acceptance/approval of financial statements.

       o    Approval of dividend payments, dividend reinvestment plans and other
            dividend-related proposals.

       o    Approval of minutes and other formalities.

                                       6


       o    Authorization of the transferring of reserves and allocation of
            income.

       o    Amendments to authorized signatories.

       o    Approval of accounting method changes or change in fiscal year-end.

       o    Acceptance of labor agreements.

       o    Appointment of internal auditors.

   Pioneer will vote on a case-by-case basis on other routine business;
   however, Pioneer will oppose any routine business proposal if insufficient
   information is presented in advance to allow Pioneer to judge the merit of
   the proposal. Pioneer has also instructed its proxy voting service to
   inform Pioneer of its analysis of any administrative items inconsistent, in
   its view, with supporting the value of Pioneer portfolio holdings so that
   Pioneer may consider and vote on those items on a case-by-case basis.

Auditors
     We normally vote for proposals to:

       o    Ratify the auditors. We will consider a vote against if we are
            concerned about the auditors' independence or their past work for
            the company. Specifically, we will oppose the ratification of
            auditors and withhold votes from audit committee members if
            non-audit fees paid by the company to the auditing firm exceed the
            sum of audit fees plus audit-related fees plus permissible tax
            fees according to the disclosure categories proposed by the
            Securities and Exchange Commission.

       o    Restore shareholder rights to ratify the auditors.

     We will normally oppose proposals that require companies to:

       o    Seek bids from other auditors.

       o    Rotate auditing firms, except where the rotation is statutorily
            required or where rotation would demonstrably strengthen financial
            disclosure.

       o    Indemnify auditors.

       o    Prohibit auditors from engaging in non-audit services for the
            company.

     Board of Directors
     On issues related to the board of directors, Pioneer normally supports
     management. We will, however, consider a vote against management in
     instances where corporate performance has been very poor or where the board
     appears to lack independence.

                                       7


     General Board Issues
     Pioneer will vote for:

       o    Audit, compensation and nominating committees composed of
            independent directors exclusively.

       o    Indemnification for directors for actions taken in good faith in
            accordance with the business judgment rule. We will vote against
            proposals for broader indemnification.

       o    Changes in board size that appear to have a legitimate business
            purpose and are not primarily for anti-takeover reasons.

       o    Election of an honorary director.

     We will vote against:

       o    Minimum stock ownership by directors.

       o    Term limits for directors. Companies benefit from experienced
            directors, and shareholder control is better achieved through
            annual votes.

       o    Requirements for union or special interest representation on the
            board.

       o    Requirements to provide two candidates for each board seat.

     We will vote on a case-by case basis on these issues:

       o    Separate chairman and CEO positions. We will consider voting with
            shareholders on these issues in cases of poor corporate
            performance.

     Elections of Directors
     In uncontested elections of directors we will vote against:

       o    Individual directors with absenteeism above 25% without valid
            reason. We support proposals that require disclosure of director
            attendance.

       o    Insider directors and affiliated outsiders who sit on the audit,
            compensation, stock option or nominating committees. For the
            purposes of our policy, we accept the definition of affiliated
            directors provided by our proxy voting service.

     We will also vote against:

       o    Directors who have failed to act on a takeover offer where the
            majority of shareholders have tendered their shares.

       o    Directors who appear to lack independence or are associated with
            very poor corporate performance.

                                       8


     We will vote on a case-by case basis on these issues:

       o    Re-election of directors who have implemented or renewed a
            dead-hand or modified dead-hand poison pill (a "dead-hand poison
            pill" is a shareholder rights plan that may be altered only by
            incumbent or "dead " directors. These plans prevent a potential
            acquirer from disabling a poison pill by obtaining control of the
            board through a proxy vote).

       o    Contested election of directors.

       o    Prior to phase-in required by SEC, we would consider supporting
            election of a majority of independent directors in cases of poor
            performance.

       o    Mandatory retirement policies.

       o    Directors who have ignored a shareholder proposal that has been
            approved by shareholders for two consecutive years.

     Takeover-Related Measures
     Pioneer is generally opposed to proposals that may discourage takeover
     attempts. We believe that the potential for a takeover helps ensure that
     corporate performance remains high.

     Pioneer will vote for:

       o    Cumulative voting.

       o    Increase ability for shareholders to call special meetings.

       o    Increase ability for shareholders to act by written consent.

       o    Restrictions on the ability to make greenmail payments.

       o    Submitting rights plans to shareholder vote.

       o    Rescinding shareholder rights plans ("poison pills").

       o    Opting out of the following state takeover statutes:

     o Control share acquisition statutes, which deny large holders voting
       rights on holdings over a specified threshold.

     o Control share cash-out provisions, which require large holders to
       acquire shares from other holders.

     o Freeze-out provisions, which impose a waiting period on large
       holders before they can attempt to gain control.

     o Stakeholder laws, which permit directors to consider interests of
       non-shareholder constituencies.

                                       9


     o Disgorgement provisions, which require acquirers to disgorge profits
       on purchases made before gaining control.

     o Fair price provisions.

     o Authorization of shareholder rights plans.

     o Labor protection provisions.

     o Mandatory classified boards.

     We will vote on a case-by-case basis on the following issues:

       o    Fair price provisions. We will vote against provisions requiring
            supermajority votes to approve takeovers. We will also consider
            voting against proposals that require a supermajority vote to
            repeal or amend the provision. Finally, we will consider the
            mechanism used to determine the fair price; we are generally
            opposed to complicated formulas or requirements to pay a premium.

       o    Opting out of state takeover statutes regarding fair price
            provisions. We will use the criteria used for fair price
            provisions in general to determine our vote on this issue.

       o    Proposals that allow shareholders to nominate directors.

     We will vote against:

       o    Classified boards, except in the case of closed-end mutual funds.

       o    Limiting shareholder ability to remove or appoint directors. We
            will support proposals to restore shareholder authority in this
            area. We will review on a case-by-case basis proposals that
            authorize the board to make interim appointments.

       o    Classes of shares with unequal voting rights.

       o    Supermajority vote requirements.

       o    Severance packages ("golden" and "tin" parachutes). We will support
            proposals to put these packages to shareholder vote.

       o    Reimbursement of dissident proxy solicitation expenses. While we
            ordinarily support measures that encourage takeover bids, we
            believe that management should have full control over corporate
            funds.

       o    Extension of advance notice requirements for shareholder proposals.

       o    Granting board authority normally retained by shareholders (e.g.,
            amend charter, set board size).

       o    Shareholder rights plans ("poison pills"). These plans generally
            allow shareholders to buy additional shares at a below-market
            price in the event of a change in control and may deter some bids.

                                       10


     Capital Structure
     Managements need considerable flexibility in determining the company's
     financial structure, and Pioneer normally supports managements' proposals
     in this area. We will, however, reject proposals that impose high barriers
     to potential takeovers.

     Pioneer will vote for:

       o    Changes in par value.

       o    Reverse splits, if accompanied by a reduction in number of shares.

       o    Share repurchase programs, if all shareholders may participate on
            equal terms.

       o    Bond issuance.

       o    Increases in "ordinary" preferred stock.

       o    Proposals to have blank-check common stock placements (other than
            shares issued in the normal course of business) submitted for
            shareholder approval.

       o    Cancellation of company treasury shares.

     We will vote on a case-by-case basis on the following issues:

       o    Reverse splits not accompanied by a reduction in number of shares,
            considering the risk of delisting.

       o    Increase in authorized common stock. We will make a determination
            considering, among other factors:

     o Number of shares currently available for issuance;

     o Size of requested increase (we would normally approve increases of up to
       100% of current authorization);

     o Proposed use of the additional shares; and

     o Potential consequences of a failure to increase the number of shares
       outstanding (e.g., delisting or bankruptcy).

       o    Blank-check preferred. We will normally oppose issuance of a new
            class of blank-check preferred, but may approve an increase in a
            class already outstanding if the company has demonstrated that it
            uses this flexibility appropriately.

       o    Proposals to submit private placements to shareholder vote.

       o    Other financing plans.

     We will vote against preemptive rights that we believe limit a company's
financing flexibility.

                                      11


     Compensation
     Pioneer supports compensation plans that link pay to shareholder returns
     and believes that management has the best understanding of the level of
     compensation needed to attract and retain qualified people. At the same
     time, stock-related compensation plans have a significant economic impact
     and a direct effect on the balance sheet. Therefore, while we do not want
     to micromanage a company's compensation programs, we will place limits on
     the potential dilution these plans may impose.

     Pioneer will vote for:

       o    401(k) benefit plans.

       o    Employee stock ownership plans (ESOPs), as long as shares
            allocated to ESOPs are less than 5% of outstanding shares. Larger
            blocks of stock in ESOPs can serve as a takeover defense. We will
            support proposals to submit ESOPs to shareholder vote.

       o    Various issues related to the Omnibus Budget and Reconciliation Act
            of 1993 (OBRA), including:

     o Amendments to performance plans to conform with OBRA;

     o Caps on annual grants or amendments of administrative features;

     o Adding performance goals; and

     o Cash or cash-and-stock bonus plans.

       o    Establish a process to link pay, including stock-option grants, to
            performance, leaving specifics of implementation to the company.

       o    Require that option repricings be submitted to shareholders.

       o    Require the expensing of stock-option awards.

       o    Require reporting of executive retirement benefits (deferred
            compensation, split-dollar life insurance, SERPs, and pension
            benefits).

       o    Employee stock purchase plans where the purchase price is equal to
            at least 85% of the market price, where the offering period is no
            greater than 27 months and where potential dilution (as defined
            below) is no greater than 10%.

                                       12


     We will vote on a case-by-case basis on the following issues:

       o    Executive and director stock-related compensation plans. We will
            consider the following factors when reviewing these plans:

       o    The program must be of a reasonable size. We will approve plans
            where the combined employee and director plans together would
            generate less than 15% dilution. We will reject plans with 15% or
            more potential dilution.

            Dilution = (A + B + C) / (A + B + C + D), where

            A = Shares reserved for plan/amendment,

            B = Shares available under continuing plans,

            C = Shares granted but unexercised and

            D = Shares outstanding.

       o    The plan must not:

            o   Explicitly permit unlimited option repricing authority or that
                have repriced in the past without shareholder approval.

            o   Be a self-replenishing "evergreen" plan, plans that grant
                discount options and tax offset payments.

     o We are generally in favor of proposals that increase participation beyond
       executives.

     o We generally support proposals asking companies to adopt rigorous
       vesting provisions for stock option plans such as those that vest
       incrementally over, at least, a three- or four-year period with a pro
       rata portion of the shares becoming exercisable on an annual basis
       following grant date.

     o We generally support proposals asking companies to disclose their
       window period policies for stock transactions. Window period policies
       ensure that employees do not exercise options based on insider
       information contemporaneous with quarterly earnings releases and other
       material corporate announcements.

     o We generally support proposals asking companies to adopt stock holding
       periods for their executives.

       o    All other employee stock purchase plans.

       o    All other compensation-related proposals, including deferred
            compensation plans, employment agreements, loan guarantee programs
            and retirement plans.

       o    All other proposals regarding stock compensation plans, including
            extending the life of a plan, changing vesting restrictions,
            repricing options, lengthening exercise periods or accelerating
            distribution of awards and pyramiding and cashless exercise
            programs.

                                       13


     We will vote against:

       o    Pensions for non-employee directors. We believe these retirement
            plans reduce director objectivity.

       o    Elimination of stock option plans.

     We will vote on a case-by case basis on these issues:

       o    Limits on executive and director pay.

       o    Stock in lieu of cash compensation for directors.

     Corporate Governance
     Pioneer will vote for:

       o    Confidential Voting.

       o    Equal access provisions, which allow shareholders to contribute
            their opinion to proxy materials.

       o    Proposals requiring directors to disclose their ownership of shares
            in the company.

     We will vote on a case-by-case basis on the following issues:

       o    Change in the state of incorporation. We will support
            reincorporations supported by valid business reasons. We will
            oppose those that appear to be solely for the purpose of
            strengthening takeover defenses.

       o    Bundled proposals. We will evaluate the overall impact of the
            proposal.

       o    Adopting or amending the charter, bylaws or articles of association.

       o    Shareholder appraisal rights, which allow shareholders to demand
            judicial review of an acquisition price.

     We will vote against:

       o    Shareholder advisory committees. While management should solicit
            shareholder input, we prefer to leave the method of doing so to
            management's discretion.

       o    Limitations on stock ownership or voting rights.

       o    Reduction in share ownership disclosure guidelines.

                                       14


     Mergers and Restructurings
     Pioneer will vote on the following and similar issues on a case-by-case
     basis:

       o    Mergers and acquisitions.

       o    Corporate restructurings, including spin-offs, liquidations, asset
            sales, joint ventures, conversions to holding company and
            conversions to self-managed REIT structure.

       o    Debt restructurings.

       o    Conversion of securities.

       o    Issuance of shares to facilitate a merger.

       o    Private placements, warrants, convertible debentures.

       o    Proposals requiring management to inform shareholders of merger
            opportunities.

     We will normally vote against shareholder proposals requiring that the
     company be put up for sale.

     Mutual Funds
     Many of our portfolios may invest in shares of closed-end mutual funds or
     exchange-traded funds. The non-corporate structure of these investments
     raises several unique proxy voting issues.

     Pioneer will vote for:

       o    Establishment of new classes or series of shares.

       o    Establishment of a master-feeder structure.

     Pioneer will vote on a case-by-case on:

       o    Changes in investment policy. We will normally support changes
            that do not affect the investment objective or overall risk level
            of the fund. We will examine more fundamental changes on a
            case-by-case basis.

       o    Approval of new or amended advisory contracts.

       o    Changes from closed-end to open-end format.

       o    Authorization for, or increase in, preferred shares.

       o    Disposition of assets, termination, liquidation, or mergers.

       o    Classified boards of closed-end mutual funds, but will typically
            support such proposals.

                                       15


     Social Issues
     Pioneer will abstain on stockholder proposals calling for greater
     disclosure of corporate activities with regard to social issues. "Social
     Issues" may generally be described as shareholder proposals for a company
     to:

       o    Conduct studies regarding certain issues of public concern and
            interest;

       o    Study the feasibility of the company taking certain actions with
            regard to such issues; or

       o    Take specific action, including ceasing certain behavior and
            adopting company standards and principles, in relation to issues
            of public concern and interest.

     We believe these issues are important and should receive management
     attention.

     Pioneer will vote against proposals calling for substantial changes in the
     company's business or activities. We will also normally vote against
     proposals with regard to contributions, believing that management should
     control the routine disbursement of funds.

                                       16


Item 8. Portfolio Managers of Closed-End Management Investment
        Companies.

(a) If the registrant is a closed-end management investment company that
is filing an annual report on this Form N-CSR,provide the following
information:
(1) State the name, title, and length of service of the person or persons
employed by or associated with the registrant or an investment adviser
of the registrant who are primarily responsible for the day-to-day management
of the registrants portfolio (Portfolio Manager). Also state each Portfolio
Managers business experience during the past 5 years.

Additional Information About the Portfolio Managers

Other Accounts Managed by the Portfolio Managers. The table below indicates, for
the portfolio manager of the fund, information about the accounts other than the
fund over which the portfolio manager has day-to-day investment responsibility.
All information on the number of accounts and total assets in the table is as of
September 30, 2010. For purposes of the table,"Other Pooled Investment Vehicles"
may include investment partnerships, undertakings for collective investments in
transferable securities ("UCITS") and other non-U.S. investment funds and group
trusts, and "Other Accounts" may include separate accounts for institutions or
individuals, insurance company general or separate accounts, pension funds and
other similar institutional accounts but generally do not include the portfolio
manager's personal investment accounts or those which the manager may be deemed
to own beneficially under the code of ethics. Certain funds and other accounts
managed by the portfolio manager may have substantially similar investment
strategies.

Potential Conflicts of Interest. When a portfolio manager is responsible for the
management of more than one account, the potential arises for the portfolio
manager to favor one account over another. The principal types of potential
conflicts of interest that may arise are discussed below. For the reasons
outlined below, Pioneer does not believe that any material conflicts are likely
to arise out of a portfolio manager's responsibility for the management of the
fund as well as one or more other accounts. Although Pioneer has adopted
procedures that it believes are reasonably designed to detect and prevent
violations of the federal securities laws and to mitigate the potential for
conflicts of interest to affect its portfolio management decisions, there can be
no assurance that all conflicts will be identified or that all procedures will
be effective in mitigating the potential for such risks. Generally, the risks of
such conflicts of interest are increased to the extent that a portfolio manager
has a financial incentive to favor one account over another. Pioneer has
structured its compensation arrangements in a manner that is intended to limit
such potential for conflicts of interest. See "Compensation of Portfolio
Managers" below.

o    A portfolio  manager could favor one account over another in allocating new
     investment  opportunities that have limited supply,  such as initial public
     offerings  and  private  placements.  If, for  example,  an initial  public
     offering  that was expected to appreciate  in value  significantly  shortly
     after the offering was allocated to a single  account,  that account may be
     expected to have better investment performance than other accounts that did
     not  receive an  allocation  of the  initial  public  offering.  Generally,
     investments  for which there is limited  availability  are allocated  based
     upon a range of factors  including  available cash and consistency with the
     accounts' investment objectives and policies.  This allocation  methodology
     necessarily  involves some subjective elements but is intended over time to
     treat  each  client  in  an  equitable  and  fair  manner.  Generally,  the
     investment  opportunity is allocated among participating  accounts on a pro
     rata basis.  Although  Pioneer  believes that its practices are  reasonably
     designed to treat each client in an equitable and fair manner, there may be
     instances where a fund may not participate,  or may participate to a lesser
     degree than other clients, in the allocation of an investment opportunity.

o    A portfolio  manager  could favor one account  over another in the order in
     which trades for the accounts are placed. If a portfolio manager determines
     to  purchase a security  for more than one account in an  aggregate  amount
     that  may  influence  the  market  price  of the  security,  accounts  that
     purchased or sold the  security  first may receive a more  favorable  price
     than accounts that made subsequent transactions. The less liquid the market
     for the security or the greater the percentage that the proposed  aggregate
     purchases or sales represent of average daily trading  volume,  the greater
     the  potential  for  accounts  that make  subsequent  purchases or sales to
     receive a less favorable price.  When a portfolio  manager intends to trade
     the same  security  on the same day for more than one  account,  the trades
     typically  are  "bunched,"  which means that the trades for the  individual
     accounts are aggregated and each account receives the same price. There are
     some  types  of  accounts  as to which  bunching  may not be  possible  for
     contractual   reasons   (such   as   directed   brokerage    arrangements).
     Circumstances  may also arise where the trader  believes  that bunching the
     orders may not result in the best possible  price.  Where those accounts or
     circumstances  are  involved,  Pioneer  will  place  the  order in a manner
     intended to result in as favorable a price as possible for such client.

o    A  portfolio  manager  could  favor an account if the  portfolio  manager's
     compensation is tied to the performance of that account to a greater degree
     than other accounts managed by the portfolio manager.  If, for example, the
     portfolio  manager  receives a bonus based upon the  performance of certain
     accounts  relative to a benchmark  while other accounts are disregarded for
     this purpose, the portfolio manager will have a financial incentive to seek
     to have the accounts that determine the portfolio  manager's  bonus achieve
     the best possible  performance to the possible detriment of other accounts.
     Similarly,  if  Pioneer  receives a  performance-based  advisory  fee,  the
     portfolio manager may favor that account, whether or not the performance of
     that account directly determines the portfolio manager's compensation.

o    A portfolio  manager could favor an account if the portfolio  manager has a
     beneficial  interest in the account,  in order to benefit a large client or
     to compensate a client that had poor returns. For example, if the portfolio
     manager held an interest in an investment  partnership  that was one of the
     accounts managed by the portfolio manager, the portfolio manager would have
     an economic  incentive to favor the account in which the portfolio  manager
     held an interest.

o    If the  different  accounts have  materially  and  potentially  conflicting
     investment  objectives or  strategies,  a conflict of interest could arise.
     For example,  if a portfolio  manager  purchases a security for one account
     and sells the same security for another  account,  such trading pattern may
     disadvantage  either the account that is long or short. In making portfolio
     manager  assignments,  Pioneer seeks to avoid such potentially  conflicting
     situations.  However, where a portfolio manager is responsible for accounts
     with differing investment  objectives and policies, it is possible that the
     portfolio  manager  will  conclude  that it is in the best  interest of one
     account to sell a portfolio  security  while another  account  continues to
     hold or increase the holding in such security.


Compensation of Portfolio Managers. Pioneer has adopted a system of compensation
for portfolio managers that seeks to align the financial interests of the
portfolio managers with those of shareholders of the accounts (including Pioneer
funds) the portfolio managers manage, as well as with the financial performance
of Pioneer. The compensation program for all Pioneer portfolio managers includes
a base salary (determined by the rank and tenure of the employee) and an annual
bonus program, as well as customary benefits that are offered generally to all
full-time employees. Base compensation is fixed and normally reevaluated on an
annual basis. Pioneer seeks to set base compensation at market rates, taking
into account the experience and responsibilities of the portfolio manager. The
bonus plan is intended to provide a competitive level of annual bonus
compensation that is tied to the portfolio manager achieving superior investment
performance and align the interests of the investment professional with those of
shareholders, as well as with the financial performance of Pioneer. Any bonus
under the plan is completely discretionary, with a maximum annual bonus that may
be in excess of base salary. The annual bonus is based upon a combination of the
following factors:

o    Quantitative   Investment   Performance.    The   quantitative   investment
     performance  calculation is based on pre-tax investment  performance of all
     of the accounts  managed by the portfolio  manager (which includes the fund
     and any other  accounts  managed by the portfolio  manager) over a one-year
     period (20% weighting) and four-year period (80%  weighting),  measured for
     periods  ending on December 31. The accounts,  which include the fund,  are
     ranked against a group of mutual funds with similar  investment  objectives
     and  investment  focus  (60%) and a  broad-based  securities  market  index
     measuring  the  performance  of the same  type of  securities  in which the
     accounts  invest  (40%),  which,  in the case of the fund,  is the Barclays
     Capital Municipal Bond Index and the Barclays Capital High Income Municipal
     Bond Index.  As a result of these two  benchmarks,  the  performance of the
     portfolio  manager  for  compensation  purposes  is  measured  against  the
     criteria that are relevant to the portfolio manager's competitive universe.

o        Qualitative Performance. The qualitative performance component with
         respect to all of the accounts managed by the portfolio manager
         includes objectives, such as effectiveness in the areas of teamwork,
         leadership, communications and marketing, that are mutually established
         and evaluated by each portfolio manager and management.

o        Pioneer Results and Business Line Results. Pioneer's financial
         performance, as well as the investment performance of its investment
         management group, affect a portfolio manager's actual bonus by a
         leverage factor of plus or minus (+/-) a predetermined percentage.

The quantitative and qualitative performance components comprise 80% and 20%,
respectively, of the overall bonus calculation (on a pre-adjustment basis). A
portion of the annual bonus is deferred for a specified period and may be
invested in one or more Pioneer funds.

Certain portfolio managers may participate in other programs designed to reward
and retain key contributors. Senior executives or other key employees may be
granted performance units based on the stock price performance of UniCredit and
the financial performance of Pioneer Global Asset Management S.p.A., which are
affiliates of Pioneer. Portfolio managers also may participate in a deferred
compensation program, whereby deferred amounts are invested in one or more
Pioneer funds.


Share Ownership by Portfolio Manager. The following table indicates as of March
31, 2010 the value, within the indicated range, of shares beneficially owned by
the portfolio manager of the fund.

Item 9. Purchases of Equity Securities by Closed-End Management
Investment Company and Affiliated Purchasers.

(a) If the registrant is a closed-end management investment company,
in the following tabular format, provide the information specified in
paragraph (b) of this Item with respect to any purchase made by or on
behalf of the registrant or any affiliated purchaser, as defined in
Rule 10b-18(a)(3) under the Exchange Act (17 CFR 240.10b-18(a)(3)), of
shares or other units of any class of the registrants equity securities
that is registered by the registrant pursuant to Section 12 of the
Exchange Act (15 U.S.C. 781). Instruction to paragraph (a). Disclose
all purchases covered by this Item, including purchases that do not
satisfy the conditions of the safe harbor of Rule 10b-18 under the
Exchange Act (17 CFR 240.10b-18), made in the period covered by the
report. Provide disclosures covering repurchases made on a monthly basis.
For example, if the reporting period began on January 16 and ended on
July 15, the chart would show repurchases for the months from January 16
through February 15, February 16 through March 15, March 16 through
April 15, April 16 through May 15, May 16 through June 15, and June 16
through July 15.

During the period covered by this report, there were no purchases
made by or on behalf of the registrant or any affiliated purchaser
as defined in Rule 10b-18(a)(3) under the Securities Exchange Act
of 1934 (the Exchange Act), of shares of the registrants equity
securities that are registered by the registrant pursuant to
Section 12 of the Exchange Act.


Item 10. Submission of Matters to a Vote of Security Holders.

Describe any material changes to the procedures by which shareholders
may recommend nominees to the registrants board of directors, where
those changes were implemented after the registrant last provided
disclosure in response to the requirements of Item 7(d)(2)(ii)(G)
of Schedule 14A (17 CFR 240.14a-101), or this Item.


There have been no material changes to the procedures by which the
shareholders may recommend nominees to the registrants board of
directors since the registrant last provided disclosure in response
to the requirements of Item 7(d)(2)(ii)(G) of Schedule 14(A) in
its definitive proxy statement, or this Item.


ITEM 11. CONTROLS AND PROCEDURES.

(a) Disclose the conclusions of the registrant's principal executive officer or
officers and principal financial officer or officers, or persons performing
similar functions, about the effectiveness of the registrant's disclosure
controls and procedures (as defined in Rule 30a-2(c) under the Act (17 CFR
270.30a-2(c))) based on their evaluation of these controls and procedures as of
a date within 90 days of the filing date of the report that includes the
disclosure required by this paragraph.

The registrant's principal executive officer
and principal financial officer have
concluded that the registrant's disclosure
controls and procedures are effective based
on their evaluation of these controls and
procedures as of a date within 90 days of the
filing date of this report.


(b) Disclose whether or not there were significant changes in the registrant's
internal controls or in other factors that could significantly affect these
controls subsequent to the date of their evaluation, including any corrective
actions with regard to significant deficiencies and material weaknesses.

There were no significant changes in the
registrant's internal control over financial
reporting that occurred during the second
fiscal quarter of the period covered by this
report that have materially affected, or are
reasonably likely to materially affect, the
registrant's internal control over financial
reporting.

The registrant's principal executive officer and principal financial
officer, however, voluntarily are reporting the following information:

In August of 2006 the registrant's investment adviser
enhanced its internal procedures for reporting performance
information required to be included in prospectuses.
Those enhancements involved additional internal controls
over the appropriateness of performance data
generated for this purpose.  Such enhancements were made
following an internal review which identified
prospectuses relating to certain classes of shares of
a limited number of registrants where, inadvertently,
performance information not reflecting the deduction of
applicable sales charges was included. Those prospectuses
were revised, and the revised prospectuses were distributed to
shareholders.


ITEM 12. EXHIBITS.

File the exhibits listed below as part of this Form. Letter or number the
exhibits in the sequence indicated.
