       Pioneer Municipal High Income Advantage Trust | Annual Report | 3/31/18 1


President's Letter

While 2017 delivered strong positive performance, 2018, thus far, has introduced
market volatility. Equity and fixed-income markets pulled back in the first
quarter of this year, as the Standard & Poor's 500 Index and the
Bloomberg Barclays U.S. Aggregate Bond Index both finished in negative
territory, returning -0.76% and -1.46%, respectively, for the three-month period
ended March 31, 2018. Concerns about the sustainability of the pace of economic
growth, extended equity valuations, and rising interest rates drove a
significant stock market sell-off beginning in late January, approaching
correction levels. The market did recover from its initial slump, but this
year's significant fluctuations have served to remind investors that even the
strongest "bulls" cannot run forever. Within fixed income, rising interest rates
helped drive down returns of most asset classes in the first quarter, though
floating-rate sectors such as bank loans fared well in the rising-rate
environment.

Our view is that the first-quarter pause in the market's near-continuous upward
momentum over the previous 15 months, dating back to the final quarter of 2016,
presents an opportunity for investors to enter the market at healthier valuation
levels. We believe fundamentals are still quite positive, yet also believe that
caution is warranted given that the market remains vulnerable to corrections.
Some areas, such as growth stocks, appear expensive, but we do see opportunity
in value stocks, with prices supported by better corporate earnings due to the
recent tax reforms in the U.S. as well as robust, nominal gross domestic product
(GDP) growth. In fact, GDP growth in the U.S. rose to close to or better than 3%
over the final three quarters of 2017, and it is anticipated that GDP growth in
the first quarter of 2018 will exceed 2%.

In the fixed-income markets, we believe investors should consider positioning
their portfolios to defend against rising interest rates, with underweight
positions in U.S. Treasuries. We see more attractive valuations within
structured investment vehicles, such as mortgage-backed securities (MBS) in both
the agency and non-agency residential MBS sectors, as fundamentals within the
U.S. housing market remain positive. We believe that agency MBS, in particular,
offer investors reasonable value.

Since 1928, the foundation of Amundi Pioneer's investment approach has been
active management, which is especially important during periods of market
volatility. We believe investors can benefit from the experience and tenure of
our investment teams who make active and informed decisions across our funds. In
fact, the Pioneer Fund, the third-oldest mutual fund in the U.S., recently
celebrated its 90th birthday. We believe the Fund serves as an important
ambassador of our time-tested value style of investing and our early focus on
understanding the benefits of investing in companies with sustainable

business models. Over its nine decades of existence - a time period that
included a Great Depression, a devastating World War, a long Cold War,
and enormous technological as well as societal changes - the Fund has been
well-served by this investment approach.

As always, and particularly during times of market uncertainty, we encourage you
to work with your financial advisor to develop an overall investment plan that
addresses both your short- and long-term goals, and to implement such a plan in
a disciplined manner.

We greatly appreciate the trust you have placed in us and look forward to
continuing to serve you in the future.

       Pioneer Municipal High Income Advantage Trust | Annual Report | 3/31/18 3


Portfolio Management Discussion | 3/31/18

The municipal bond market generated positive results over the 12-month period
ended March 31, 2018, with high-yield municipals outperforming investment-grade
municipals. In the following interview, David Eurkus and Jonathan Chirunga
discuss the factors that influenced the performance of Pioneer Municipal High
Income Advantage Trust during the 12-month period. Mr. Eurkus, Managing
Director, Director of Municipals, U.S., and a portfolio manager at Amundi
Pioneer Asset Management, Inc. ("Amundi Pioneer"), and Mr. Chirunga, a senior
vice president and a portfolio manager at Amundi Pioneer, are responsible for
the day-to-day management of the Trust.

Q    How did Pioneer Municipal High Income Advantage Trust perform during the
     12-month period ended March 31, 2018?

A    Pioneer Municipal High Income Advantage Trust returned 3.11% at net asset
     value (NAV) and 2.92% at market price during the 12-month period ended
     March 31, 2018. During the same 12-month period, the Trust's benchmarks,
     the Bloomberg Barclays U.S. Municipal High Yield Bond Index and the
     Bloomberg Barclays Municipal Bond Index, returned 6.03% and 2.66% at NAV,
     respectively. The Bloomberg Barclays U.S. Municipal High Yield Bond Index
     is an unmanaged measure of the performance of lower-rated municipal bonds,
     while the Bloomberg Barclays Municipal Bond Index is an unmanaged measure
     of the performance of investment-grade municipal bonds. Unlike the Trust,
     the two indices do not use leverage. While use of leverage increases
     investment opportunity, it also increases investment risk.

     During the same 12-month period, the average return (at market price) of
     the 14 closed-end funds in Morningstar's High Yield Municipal Debt Closed
     End Funds category (which may or may not be leveraged) was 1.37%, and the
     average return at NAV of the 14 closed-end funds in the same Morningstar
     category was 5.24%.

     The shares of the Trust were selling at a 7.5% discount to NAV on March 31,
     2018. Comparatively, the shares of the Trust were selling at a 7.3%
     discount to NAV on March 31, 2017.

     On March 31, 2018, the standardized 30-day SEC yield of the Trust's shares
     was 4.10%*.

*    The 30-day SEC yield is a standardized formula that is based on the
     hypothetical annualized earning.

Q    How would you describe the investment environment in the municipal bond
     market during the 12-month period ended March 31, 2018?

A    A favorable backdrop continued to support the municipal bond market over
     the 12-month period, as both economic fundamentals and technical factors
     helped municipal debt turn in positive performance. Favorable fundamentals
     included a persistently growing economy with improving corporate profits,
     low inflation, and a U.S. Federal Reserve System (the Fed) that acted to
     gradually tighten monetary policy. Over the period, the Fed raised the
     federal funds rate three times, in June 2017, December 2017, and March
     2018.

     In 2017, longer-term interest rates were gradually falling and short-term
     rates rising, with the yield curve flattening. Demand for
     fixed-income instruments, including municipal bonds, was steady, as
     investors continued to search for yield in a generally low-rate
     environment. As 2017 drew to a close, the U.S. economy posted stronger
     results, with unemployment falling to 4.1% and inflation remaining low and
     stable. Up until December, municipal security issuance was fairly light.

     However, the possibility of the first major overhaul to the U.S. tax code
     since 1986 also loomed large during the fourth quarter of 2017, and
     uncertainty over the content of the new tax package roiled the municipal
     market. When the legislation was finalized in December, one of its
     provisions had a heavy impact on "advance refunding" bonds within the
     municipal market. Advance refunding refers to when one municipal bond
     issuance is used to pay off another outstanding municipal bond. The new
     bond is issued at a lower interest rate than the older, unpaid obligation.
     Municipalities typically use advance refundings to reduce borrowing costs
     and to take advantage of lower interest rates. However, under the new tax
     law, after December 31, 2017, interest on a municipal bond issued to
     advance refund another municipal bond more than 90 days prior to the
     refunded bond's call date is no longer tax exempt.

     While interest on refunding bonds issued within 90 days of the original
     municipal bond's call date remains tax exempt, it is expected that the
     elimination of the tax exemption on advance refunding bonds could reduce
     municipal supply by as much as 15 to 20 percent going forward. In December
     2017, after the terms of the tax bill were announced, a host of municipal
     entities rushed to issue advance refunding bonds before the legislation
     took effect. That drove municipal issuance for December to a
     record-breaking $62.5 billion, and total 2017 issuance to $425 billion,
     much higher than forecast at the start of 2017. Another provision within
     the tax bill was the decrease in the state and local property tax deduction
     for

       Pioneer Municipal High Income Advantage Trust | Annual Report | 3/31/18 5


     individuals, now limited to a $10,000 maximum. The change promised to make
     municipal bonds more attractive given that investors would likely seek to
     shelter their taxable income in other ways.

     Over the final three months of the period, municipal issuance was light, as
     many municipalities had already issued their bonds before January 1, when
     the law regarding advance refundings was changed. In turn, demand for
     municipal bonds began to creep up in February 2018, as investors,
     especially those from higher-tax states such as California, New York,
     Massachusetts, and New Jersey, purchased tax-exempt securities at increased
     levels.

     High-yield municipal bonds outperformed investment-grade municipals during
     the period, by a fairly significant margin.

Q    What factors affected the Trust's performance relative to the Bloomberg
     Barclays municipal bond indices during the 12-month period ended March 31,
     2018?

A    We maintained a well-diversified** portfolio during the period, with
     exposures to both investment-grade and high-yield municipal bonds. The
     portfolio's diversification across different municipal sectors helped the
     Trust's return exceed that of the Bloomberg Barclays Municipal Bond Index,
     which tracks investment-grade municipals, even as it trailed the return of
     the Bloomberg Barclays U.S. Municipal High Yield Bond Index during a period
     which saw high-yield municipals outperform.

     The portfolio's holdings of certain tobacco bonds funded by Master
     Settlement Agreements between the tobacco industry and individual states,
     as well as an allocation to general obligation bonds issued by the
     Commonwealth of Puerto Rico contributed to the Trust's performance during
     the period.

     Conversely, holdings in the Trust's portfolio that underperformed during
     the period included bonds issued by Sanger (Texas) Industrial Development
     Corporation, which has experienced ongoing credit problems that have
     contributed to a moderate decrease in value, and municipal bonds issued by
     the City of Philippi, West Virginia.

     The City of Philippi (education bond) obligation is an older portfolio
     holding that dates back to before the current team took over day-to-day
     management responsibilities for the Trust. The bonds funded several
     projects at a small college in rural West Virginia that have not been
     additive to the school's bottom line. However, the Trust is currently
     receiving

     payments from the issuer under the terms of a forbearance agreement we
     negotiated, and will receive a total of $1.4 million by the time the
     agreement expires in October 2018. Prior to the forbearance agreement, the
     Trust was realizing no income from the City of Philippi bond. Meanwhile,
     the administrative staff of the school has changed, and we are optimistic
     about the bond's forward-looking prospects based on the new administrators'
     efforts in continuing to work through the school's problems.

Q    Did the Trust's distributions*** to shareholders change during the 12-month
     period ended March 31, 2018?

A    Yes, the Trust's distributions increased slightly over the 12-month period.

Q    Did the level of leverage in the Trust change during the 12-month period
     ended March 31, 2018?

A    At the end of the 12-month period on March 31, 2018, 36.6% of the Trust's
     total managed assets were financed by leverage obtained through the
     issuance of preferred shares, compared with 34.6% of the Trust's total
     managed assets financed by leverage at the start of the period on April 1,
     2017. The Trust historically employed leverage through the issuance of
     Auction Preferred Shares ("APS"). The Trust redeemed all of its outstanding
     APS on February 20, 2018. The Trust refinanced the APS, and increased the
     amount of leverage employed by the Trust, through the issuance of Variable
     Rate Muni Fund Term Preferred Shares ("VMTP Shares"). VMTP Shares are
     issued via private placement and are not publicly available. The increase
     in leverage as a percentage of the Trust's total managed assets during the
     12-month period was due to the increase in the par value of the VMTP
     Shares compared to that of the APS.

Q    Did the Trust invest in any derivative securities during the 12-month
     period ended March 31, 2018?

A    No, the Trust's portfolio held no derivative securities during the period.

Q    What is your investment outlook?

A    We maintain an optimistic view of the municipal bond market, as its
     underlying fundamentals remain strong and investor demand is steady. In
     addition, we believe we are entering what looks to be a strong technical
     period for municipals from May through July of this year. Those three
     months typically feature the largest volume of municipal bond coupon

***  Distributions are not guaranteed.

       Pioneer Municipal High Income Advantage Trust | Annual Report | 3/31/18 7


     interest payments and maturities, which investors will most likely seek to
     reinvest in tax-free securities. The technical situation could translate
     into a significant increase in demand. Meanwhile, as mentioned, following
     the surge in supply in December 2017, municipal supply in 2018 has been
     limited. Additionally, we believe that healthy demand from both traditional
     and non-traditional investors drawn to the municipal market by the
     attractive value and generous yields of municipal bonds - as compared with
     yields available on taxable debt instruments - can continue to outstrip the
     limited new-issue supply and help to support the prices of municipal bonds.

     At the same time, we think that the U.S. economy should continue to grow at
     a stable and steady pace, without an accompanying acceleration in
     inflation. We also believe that the Fed will continue to act deliberately
     and cautiously as it gradually raises short-term rates.

     In managing the Trust going forward, we will continue to monitor events
     carefully and remain focused on intensive, fundamental research, while
     maintaining a well-diversified portfolio with exposures to both
     investment-grade and high-yield municipal securities.

Please refer to the Schedule of Investments on pages 13-22 for a full listing of
Trust securities.

All investments are subject to risk, including the possible loss of principal.
In the past several years, financial markets have experienced increased
volatility, depressed valuations, decreased liquidity and heightened
uncertainty. These conditions may continue, recur, worsen or spread.

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.

8 Pioneer Municipal High Income Advantage Trust | Annual Report | 3/31/18


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 the issuers' inability
to meet their debt obligations.

The Trust currently uses leverage through the issuance of preferred shares.
Leverage creates significant risks, including the risk that the Trust's
incremental income or capital appreciation for investments purchased with the
proceeds of leverage will not be sufficient to cover the cost of leverage, which
may adversely affect the return for the holders of common shares.

The Trust is required to meet 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, which is
likely to result in a decrease in the market value of the Trust's shares.

These risks may increase share price volatility.

Call 1-800-225-6292 or visit www.amundipioneer.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 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.

Shares of 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 bought and 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 include 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 through open-market purchases 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.
Had these fees and taxes been reflected, performance would have been lower.

The Bloomberg Barclays Municipal Bond Index is an unmanaged, broad measure of
the municipal bond market. The Bloomberg Barclays U.S. Municipal High Yield Bond
Index is unmanaged, totals over $26 billion in market value and maintains over
1,300 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 do not employ leverage.
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, as a secondary objective, also
seek capital appreciation to the extent that it is consistent with its primary
investment objective.

On July 3, 2017, Amundi acquired Pioneer Investments, a group of asset
management companies located throughout the world. Amundi, one of the world's
largest asset managers, is headquartered in Paris, France. As a result of the
transaction, Pioneer Investment Management, Inc., the Trust's investment
adviser, became an indirect wholly owned subsidiary of Amundi and Amundi's
wholly owned subsidiary, Amundi USA, Inc. Prior to July 3, 2017, Pioneer
Investments was owned by Pioneer Global Asset Management S.p.A., a wholly owned
subsidiary of UniCredit S.p.A.

In connection with the transaction, the names of the Trust's investment adviser
and principal underwriter changed. Effective July 3, 2017, the name of Pioneer
Investment Management, Inc. changed to Amundi Pioneer Asset Management, Inc.
(the "Adviser") and the name of Pioneer Funds Distributor, Inc. changed to
Amundi Pioneer Distributor, Inc. (the "Distributor").

In October 2016, the Securities and Exchange Commission (SEC) released its Final
Rule on Investment Company Reporting Modernization. In addition to introducing
two new regulatory reporting forms (Form N-PORT and Form N-CEN), the Final Rule
amends Regulation S-X, which impacts financial statement presentation,
particularly related to the presentation of derivative investments. The Fund's
financial statements were prepared in compliance with the amendments to
Regulation S-X.

The Trust's financial statements have been prepared in conformity with U.S.
generally accepted accounting principles ("U.S. GAAP") that require the
management of the Trust to 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
period. Actual results could differ from those estimates.

28 Pioneer Municipal High Income Advantage Trust | Annual Report | 3/31/18


The Trust is an investment company and follows investment company accounting and
reporting guidance under U.S. GAAP. The following is a summary of significant
accounting policies followed by the Trust in the preparation of its financial
statements:

A.   Security Valuation

     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-income securities are valued by using 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, or may use a pricing matrix or other fair value
     methods or techniques to provide an estimated value of the security or
     instrument. A pricing matrix is a means of valuing a debt security on the
     basis of current market prices for other debt securities, historical
     trading patterns in the market for fixed income securities and/or other
     factors. Non-U.S. debt securities that are listed on an exchange will be
     valued at the bid price obtained from an independent third party pricing
     service. When independent third party pricing services are unable to supply
     prices, or when prices or market quotations are considered to be
     unreliable, the value of that security may be determined using quotations
     from one or more broker-dealers.

     Securities or loan interests for which independent pricing services or
     broker-dealers 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 by a fair valuation team comprised of certain
     personnel of the Adviser, pursuant to procedures adopted by the Trust's
     Board of Trustees. The Adviser's fair valuation team uses fair value
     methods approved by the Valuation Committee of the Board of Trustees. The
     Adviser's fair valuation team is responsible for monitoring developments
     that may impact fair valued securities and for discussing and assessing
     fair values on an ongoing basis, and at least quarterly, with the Valuation
     Committee of the Board of Trustees.

     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. 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. Examples of a significant
     event might include political or economic news, corporate restructurings,
     natural disasters, terrorist activity or trading halts. Thus, the valuation
     of the Trust's securities may differ significantly from exchange prices and
     such differences could be material.

      Pioneer Municipal High Income Advantage Trust | Annual Report | 3/31/18 29


     At March 31, 2018, two securities were valued using fair value methods (in
     addition to securities valued using prices supplied by independent pricing
     services, broker-dealers or using third party insurance pricing model)
     representing 2.54% of net assets. The value of these fair valued securities
     was $7,042,000.

B.   Investment Income and Transactions

     Interest income, including interest on income-bearing cash accounts, is
     recorded on the accrual basis, net of unrecoverable foreign taxes withheld
     at the applicable country rates and net of income accrued or defaulted
     securities.

     Discounts and premiums on purchase prices of debt securities are accreted
     or amortized, respectively, daily, into interest income on an effective
     yield to maturity basis with a corresponding increase or decrease in the
     cost basis of the security. Premiums and discounts related to certain
     mortgage-backed securities are amortized or accreted in proportion to the
     monthly paydowns. Interest and dividend income payable by delivery of
     additional shares is reclassified as PIK ("payment-in-kind") income upon
     receipt and is included in interest income.

     Security transactions are recorded as of trade date. Gains and losses on
     sales of investments are calculated on the identified cost method for both
     financial reporting and federal income tax purposes.

C.   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 net taxable income and net realized capital gains, if any, to
     its shareowners. Therefore, no provision for federal Income taxes is
     required. As of March 31, 2018, the Trust did not accrue any interest or
     penalties with respect to uncertain tax positions, which, if applicable,
     would be recorded as an income tax expense on the Statement of Operations.
     Tax returns filed within the prior three years remain subject to
     examination by federal and state tax authorities.

     The amount and character of income and capital gain distributions to
     shareowners are determined in accordance with federal income tax rules,
     which may differ from U.S. GAAP. Distributions in excess of net investment
     income or net realized gains are temporary overdistributions for financial
     statement purposes resulting from differences in the recognition or
     reclassification of income or distributions for financial statement and tax
     purposes. Capital accounts within the financial statements are adjusted for
     permanent book/tax differences to reflect tax character, but are not
     adjusted for temporary differences.

30 Pioneer Municipal High Income Advantage Trust | Annual Report | 3/31/18


     At March 31, 2018, the Trust reclassified $18,242,633 to decrease paid-in
     capital, $403,149 to increase undistributed net investment income and
     $17,839,484 to decrease accumulated net realized loss on investments to
     reflect permanent book/tax differences. These adjustments have no impact on
     the net assets or results of operations.

     At March 31, 2018, the Trust was permitted to carry forward $1,186,929 of
     short-term capital losses and $26,097,368 of long-term capital losses
     without limitation. Additionally, at March 31, 2018, the Trust had a net
     capital loss carry forward of $2,659,411 which will expire in 2019 if not
     utilized. Capital loss not utilized and expired in 2018 amounts to
     $18,242,633. Since unlimited losses are required to be used first, loss
     carry forwards that are subject to expiration may be more likely to expire
     unused.

     The tax character of distributions paid to shareowners during the years
     ended March 31, 2018 and March 31, 2017 were as follows:



     ---------------------------------------------------------------------------
                                                           2018            2017
     ---------------------------------------------------------------------------
                                                              
     Distributions paid from:
     Tax exempt income                              $16,843,525     $18,477,950

D.   Automatic Dividend Reinvestment Plan

     All 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 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 dividends in shares of the
     Trust on terms that differ from the terms of the Plan.

     Whenever the Trust declares a dividend on shares payable in cash,
     participants in the Plan will receive the equivalent in shares acquired by
     the Plan Agent either (i) through receipt of additional unissued but
     authorized shares from the Trust or (ii) by purchase of outstanding shares
     on the New York Stock Exchange or elsewhere. If, on the payment date for
     any dividend, the net asset value per 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
     shares. The number of newly issued shares to be credited to each account
     will be determined by dividing the dollar amount of the dividend by the net
     asset value per 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 share is greater than the market value (market
     discount), the Plan Agent will invest the dividend amount in shares
     acquired in open-market purchases. There are no brokerage charges with
     respect to newly issued 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 be able to transfer the shares to another broker and
     continue to participate in the Plan.

E.   Risks

     The value of securities held by the Trust may go up or down, sometimes
     rapidly or unpredictably, due to general market conditions, such as real or
     perceived adverse economic, political or regulatory conditions, inflation,
     changes in interest rates, lack of liquidity in the bond markets or adverse
     investor sentiment. In the past several years, financial markets have
     experienced increased volatility, depressed valuations, decreased liquidity
     and heightened uncertainty. These conditions may continue, recur, worsen or
     spread.

     Interest rates in the U.S. recently have been historically low, so the
     Trust faces a heightened risk that interest rates may rise. A general rise
     in interest rates may cause investors to move out of fixed income
     securities on a large scale, which could adversely affect the price and
     liquidity of fixed income securities.

     The municipal bond market can be susceptible to unusual volatility,
     particularly for lower-rated and unrated securities. Liquidity can be
     reduced unpredictably in response to overall economic conditions or credit
     tightening. Municipal issuers may be adversely affected by rising health
     care costs, increasing unfunded pension liabilities, and by the phasing out
     of federal programs providing financial support. Unfavorable conditions and
     developments relating to projects financed with municipal securities can
     result in lower revenues to issuers of municipal securities, potentially
     resulting in defaults. Issuers often depend on revenues from these projects
     to make principal and interest payments. The value of municipal securities
     can also be adversely affected by changes in the financial condition of one
     or more individual municipal issuers or insurers of municipal issuers,
     regulatory and political developments, tax law changes or other legislative
     actions, and by uncertainties and public perceptions concerning these and
     other factors. Municipal securities may be more susceptible to down-grades
     or defaults during recessions or similar periods of economic stress. In
     recent periods, an increasing number of municipal issuers in the United
     States have defaulted on obligations and commenced insolvency proceedings.
     Financial difficulties of municipal issuers may continue or get worse. To
     the extent the Trust invests significantly in a single state, including
     California, Massachusetts and Texas, or in securities the payments on which
     are dependent upon a single project or source of revenues, or that relate
     to a sector or industry, including health care facilities, education,
     transportation, special revenues and pollution control, the Trust will be
     more susceptible to associated risks and developments.

     With the increased use of technologies such as the Internet to conduct
     business, the Trust is susceptible to operational, information security and
     related risks. While the Trust's adviser has established business
     continuity plans in the event of, and risk management systems to prevent,
     limit or mitigate, such cyber-attacks, there are inherent limitations in
     such plans and systems including the possibility that certain risks have
     not been identified.

      Pioneer Municipal High Income Advantage Trust | Annual Report | 3/31/18 33


     Furthermore, the Trust cannot control the cybersecurity plans and systems
     put in place by service providers to the fund such as Brown Brothers
     Harriman & Co., the fund's custodian and accounting agent, and American
     Stock Transfer & Trust Company ("AST"), the Trust's transfer agent. In
     addition, many beneficial owners of Trust shares hold them through accounts
     at broker-dealers, retirement platforms and other financial market
     participants over which neither the Trust nor Amundi Pioneer exercises
     control. Each of these may in turn rely on service providers to them, which
     are also subject to the risk of cyber-attacks. Cybersecurity failures or
     breaches at Amundi Pioneer or the Trust's service providers or
     intermediaries have the ability to cause disruptions and impact business
     operations potentially resulting in financial losses, interference with the
     Trust's ability to calculate its NAV, impediments to trading, the inability
     of Trust shareholders to effect share purchases or receive distributions,
     loss of or unauthorized access to private shareholder information and
     violations of applicable privacy and other laws, regulatory fines,
     penalties, reputational damage, or additional compliance costs. Such costs
     and losses may not be covered under any insurance. In addition, maintaining
     vigilance against cyber-attacks may involve substantial costs over time,
     and system enhancements may themselves be subject to cyber-attacks.

2. Management Agreement

The Adviser manages the Trust's portfolio. Management fees payable under the
Trust's Advisory Agreement with the Adviser 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 or the issuance of debt
securities), (ii) the issuance of preferred stock or other similar preference
securities, and/or (iii) any other means. For the year ended March 31, 2018, the
net management fee was 0.60% of the Trust's average daily managed assets, which
was equivalent to 0.92% of the Trust's average daily net assets.

In addition, under the Adviser's management and administration agreements,
certain other services and costs are paid by the Adviser and reimbursed by the
Trust. At March 31, 2018, $28,366, was payable to the Adviser related to
management costs, administrative costs and certain other services is included in
"Due to affiliates" on the Statement of Assets and Liabilities.

34 Pioneer Municipal High Income Advantage Trust | Annual Report | 3/31/18


3. Transfer Agent

American Stock Transfer & Trust Company ("AST") serves as the transfer agent
with respect to the Trust's common shares. The Trust pays AST an annual fee, as
is agreed to from time to time by the Trust and AST, for providing such
services.

In addition, the Trust reimbursed the transfer agent for out-of-pocket expenses
incurred by the transfer agent related to shareowner communications activities
such as proxy and statement mailings and outgoing calls.

Deutsche Bank Trust Company Americas ("Deutsche Bank") served as the transfer
agent, registrar, dividend-paying agent and auction agent with respect to the
Trust's auction preferred shares ("APS"). The Trust paid Deutsche Bank an annual
fee for providing such services.

4. Trust Shares

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

Transactions in common shares of beneficial interest for the years ended March
31, 2018 and March 31, 2017 were as follows:

================================================================================


The Trust may classify or reclassify any unissued shares of beneficial interest
into one or more series of preferred shares of beneficial interest.

As of March 31, 2018, the Trust has outstanding 1,600 Variable Rate Munifund
Term Preferred Shares Series 2021 ("series 2021 VMTP Shares or "VMTP Shares").
The trust issued the VMTP Shares on February 20, 2018. See Note 5 for additional
information.

Prior to February 20, 2018, the Trust had outstanding 3,000 Series A APS and
3,000 Series B APS. The Trust redeemed all outstanding Series A APS and Series B
APS on February 20, 2018. See Note 6 for additional information.

5. Variable Rate MuniFund Term Preferred Shares

The Trust has 1,600 shares issued and outstanding of Series 2021 VMTP Shares,
with a liquidation preference of $100,000 per share. VMTP Shares are issued via
private placement and are not publicly available.

The Trust is obligated to redeem its VMTP Shares by the date as specified in its
offering document ("Term Redemption Date"), unless earlier redeemed by the
Trust. VMTP Shares are subject to optional and mandatory redemption in

      Pioneer Municipal High Income Advantage Trust | Annual Report | 3/31/18 35


certain circumstances. The VMTP Shares may be redeemed at the option of the
Trust, subject to payment of premium for approximately one year following the
date of issuance ("Optional Redemption Date"), and at the redemption price per
share thereafter. The redemption price per share is equal to the sum of the
liquidation preference per share plus any accumulated but unpaid dividends. The
Trust may be obligated to redeem a certain amount of the VMTP Shares if it fails
to maintain certain asset coverage and leverage ratio requirements and such
failures are not cured by the applicable cure date. The Term Redemption Date and
Optional Redemption Date for the Trust's Series 2021 VMTP Shares are August 2,
2021 and February 28, 2019, respectively.

VMTP Shares are subject to restrictions on transfer, generally do not trade, and
market quotations are generally not available. VMTP Shares are short-term or
short/intermediate-term instruments that pay a variable dividend rate tied to a
short-term index, plus an additional fixed "spread" amount established at the
time of issuance. For financial reporting purposes, the liquidation preference
of VMTP Shares is a liability and is recognized as a component of "Variable Rate
MuniFund Term Preferred Shares, net of deferred offering costs" on the Statement
of Assets and Liabilities.

Dividends on the VMTP Shares (which are treated as interest payments for
financial reporting purposes) are declared daily. The dividend rate for the VMTP
Shares is determined weekly. Unpaid dividends on VMTP Shares are recognized as a
component of "Dividend payable" on the Statement of Assets and Liabilities. From
February 22, 2018 (issuance) through March 31, 2018, the Series 2021 VMTP Shares
paid an average dividend rate of 2.26%.

Costs incurred in connection with the Trust's offering of VMTP Shares were
recorded as a deferred charge, which is being amortized over the life of the
shares and is recognized as a component of "Variable Rate MuniFund Term
Preferred Shares, net of deferred offering costs" on the Statement of Assets and
Liabilities.

Transactions in the Series 2021 VMTP Shares during the Trust's current and prior
reporting periods were as follows:

--------------------------------------------------------------------------------


7. Dividends to APS

Prior to the redemption of the Trust's APS (See Note 6), dividends on Series A
and Series B were cumulative at a rate which reset every seven days based on the
results of an auction. Since February 2008, the Trust's auctions related to the
APS failed. Accordingly, during the period, dividends were paid at the maximum
rate on the auction dates described in the prospectus for the APS. The maximum
rate for each series was 125% of the 7 day commercial paper rate or adjusted
Kenny rate. Dividend rates on APS ranged from 1.276% to 3.491% during the year
ended March 31, 2018.

8. Subsequent Events

A monthly dividend was declared on May 4, 2018 from undistributed and
accumulated net investment income of $0.0525 per common share payable May 31,
2018, to common shareowners of record on May 16, 2018.

Subsequent to March 31, 2018, dividends declared and paid on VMTP Shares totaled

Report of Independent Registered Public Accounting Firm

To the Board of Trustees and the Shareholders of
Pioneer Municipal High Income Advantage Trust:
--------------------------------------------------------------------------------

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities of Pioneer
Municipal High Income Advantage Trust (the "Trust"), including the schedule of
investments, as of March 31, 2018, and the related statements of operations,
changes in net assets, and the financial highlights for the year then ended and
the related notes and the financial highlights for the year ended March 31, 2014
(collectively referred to as the "financial statements"). The statement of
changes in net assets for the year ended March 31, 2017 and the financial
highlights for the periods ended March 31, 2015, March 31, 2016 and March 31,
2017 were audited by another independent registered public accounting firm whose
report, dated May 26, 2017, expressed an unqualified opinion on the statement of
changes in net assets and those financial highlights. In our opinion, the
financial statements present fairly, in all material respects, the financial
position of Pioneer Municipal High Income Advantage Trust at March 31, 2018, the
results of its operations, the changes in its net assets, and the financial
highlights for the year ended and the financial highlights for the year ended
March 31, 2014, in conformity with U.S. generally accepted accounting
principles.

Basis for Opinion

These financial statements are the responsibility of the Trust's management. Our
responsibility is to express an opinion on the Trust's financial statements
based on our audits. We are a public accounting firm registered with the Public
Company Accounting Oversight Board (United States) ("PCAOB") and are required to
be independent with respect to the Trust in accordance with the U.S. federal
securities laws and the applicable rules and regulations of the Securities and
Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those
standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement, whether due to error or fraud. The Trust is not required to have,
nor were we engaged to perform, an audit of the Trust's internal control over
financial reporting. As part of our audits, we are required to obtain an
understanding of internal control over financial reporting, but not for the
purpose of expressing an opinion on the effectiveness of the Trust's internal
control over financial reporting. Accordingly, we express no such opinion.

38 Pioneer Municipal High Income Advantage Trust | Annual Report | 3/31/18


Our audits included performing procedures to assess the risks of material
misstatement of the financial statements, whether due to error or fraud, and
performing procedures that respond to those risks. Such procedures included
examining, on a test basis, evidence regarding the amounts and disclosures in
the financial statements. Our procedures included confirmation of securities
owned as of March 31, 2018, by correspondence with the custodian and brokers.
Our audits also included evaluating the accounting principles used and
significant estimates made by management, as well as evaluating the overall
presentation of the financial statements. We believe that our audits provide a
reasonable basis for our opinion.

                                                           /s/ Ernst & Young LLP

Boston, Massachusetts
We have served as the Trust's auditor since 2017.

ADDITIONAL INFORMATION (unaudited)

During the period, there have been no material changes in the Trust's investment
objective or fundamental policies that have not been approved by the
shareowners. There have been no changes in the Trust's charter or By-Laws that
would delay or prevent a change in control of the Trust which has not been
approved by the shareowners. During the period, there have been no changes in
the principal risk factors associated with investment in the Trust. There were
no changes in the persons who are primarily responsible for the day-to-day
management of the Trust's portfolio.

Notice is hereby given in accordance with Section 23(c) of the Investment
Company Act of 1940 that the Trust may purchase, from time to time, its common
shares in the open market.

Change in Independent Registered Public Accounting Firm

Prior to July 3, 2017 Pioneer Investment Management, Inc. (the "Adviser"), the
Trust's investment adviser, was an indirect, wholly owned subsidiary of
UniCredit S.p.A. ("UniCredit"). On that date, UniCredit completed the sale of
its Pioneer Investments business, which includes the Adviser, to Amundi (the
"Transaction"). As a result of the Transaction, the Adviser became an indirect,
wholly owned subsidiary of Amundi. Amundi is controlled by Credit Agricole S.A.
Amundi is headquartered in Paris, France, and, as of September 30, 2016, had
more than $1.1 trillion in assets under management worldwide.

Deloitte & Touche LLP ("D&T"), the Trust's previous independent registered
public accounting firm, informed the Audit Committee and the Board that it would
no longer be independent with respect to the Trust upon the completion of the
Transaction as a result of certain services being provided to Amundi and Credit
Agricole, and, accordingly, that it intended to resign as the Trust's
independent registered public accounting firm upon the completion of the
Transaction. D&T's resignation was effective on July 3, 2017, when the
Transaction was completed.

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

40 Pioneer Municipal High Income Advantage Trust | Annual Report | 3/31/18


Effective immediately following the completion of the Transaction on July 3,
2017, the Board, acting upon the recommendation of the Audit Committee, engaged
a new independent registered public accounting firm, Ernst & Young LLP ("EY"),
for the Trust's fiscal year ended July 31, 2017.

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

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

 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 Amudi Pioneer Asset Management, Inc, 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.

registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of
Rule 2-01 of Regulation S-X is compatible with maintaining the principal
accountant's independence.

The Fund's audit committee of the Board of Trustees
has considered whether the provision of non-audit
services that were rendered to the Affiliates (as
defined) that were not pre- approved pursuant to
paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is
compatible with maintaining the principal accountant's
independence.

ITEM 5. AUDIT COMMITTEE OF LISTED REGISTRANTS

(a) If the registrant is a listed issuer as defined in Rule 10A-3
under the Exchange Act (17 CFR 240.10A-3), state whether
or not the registrant has a separately-designated standing
 audit committee established in accordance with Section
3(a)(58)(A) of the Exchange Act (15 U.S.C. 78c(a)(58)(A)).
If the registrant has such a committee, however designated,
identify each committee member. If the entire board of directors
is acting as the registrant's audit committee as specified in
Section 3(a)(58)(B) of the Exchange Act (15 U.S.C. 78c(a)(58)(B)),
so state.

(b) If applicable, provide the disclosure required by Rule 10A-3(d)
under the Exchange Act (17 CFR 240.10A-3(d)) regarding an exemption
from the listing standards for audit committees.

ITEM 7. DISCLOSURE OF PROXY VOTING POLICIES AND PROCEDURES FOR
CLOSED-END MANAGEMENT INVESTMENT COMPANIES.

A closed-end management investment company that is filing an annual report on
this Form N-CSR must, unless it invests exclusively in non-voting securities,
describe the policies and procedures that it uses to determine how to vote
proxies relating to portfolio securities, including the procedures that the
company uses when a vote presents a conflict between the interests of its
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
investment adviser, or any other third party, that the company uses, or that are
used on the company's behalf, to determine how to vote proxies relating to
portfolio securities.

                      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.

                                       1


                             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

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, Amundi 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 Amundi 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. Amundi 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


                                       0


 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 Amundi 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,
  Amundi 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 Amundi 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, Amundi 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 MANAGER
Amundi 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 Amundi Pioneer. The
compensation program for all Amundi 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. Amundi Pioneer seeks to set base compensation at market rates,
taking into account the


                                       1


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 Amundi 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 Yield 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 AMUNDI PIONEER RESULTS AND BUSINESS LINE RESULTS. Amundi 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 participate in other programs designed to reward and
retain key contributors. Portfolio managers also may participate in a deferred
compensation program, whereby deferred amounts are invested in one or more
Pioneer funds.

shares or other units of any class of the registrant's equity securities
that is registered by the registrant pursuant to Section 12 of the

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 registrant's board of directors, where
those changes were implemented after the registrant last provided
disclosure in response to the requirements of Item 407(c)(2)(iv) of
Regulation S-R(17 CFR 229.407)(as required by Item 22(b)(15))
of Schedule 14A (17 CFR 240.14a-101), or this Item.


There have been no material changes to the procedures by which the

in its definitive proxy statement, or this item.


ITEM 11. CONTROLS AND PROCEDURES.

(a) Disclose the conclusions of the registrant's principal executive and
principal financials officers, or persons performing similar functions,
regarding the effectiveness of the registrant's disclosure
controls and procedures (as defined in Rule 30a-3(c) under the Act (17 CFR
270.30a-3(c))) as of a date within 90 days of the filing date of the report
that includes the disclosure required by this paragraph,
based on the evaluation of these controls and procedures required by Rule
30a-3(b) under the Act (17 CFR 270.30(a)-3(b) and Rules 13a-15(b) or 15d-15(b)
under the Exchange Act (17 CFR 240.13a-15(b) or 240.15d-15(b)).

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


(b) Disclose any change in the registrant's internal control over financial
reporting (as defined in Rule 30a-3(d) under the Act (17CFR 270.30a-3(d)) that
occured during the second fiscal quarter of the period covered by this report
that has materially affected, or is reasonably likely to materially affect,
the registrant's internal control over financial reporting.

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.
