               Pioneer Diversified High Income Trust | Annual Report | 4/30/13 1


President's Letter

Dear Shareowner,

Pioneer continues to see only modest economic growth in the U.S. Employment
continues to rise, albeit slowly, and we believe it will continue to do so in
2013, barring a negative shock to the system. The housing and auto sectors
continue to recover, benefiting from record-low interest rates. Banks'
willingness to lend to consumers and businesses also continues to rise, broad
measures of inflation remain subdued, and, if the weather cooperates in 2013,
food prices should come back down. And, while corporate profit growth has
slowed, profits remain high and many U.S. companies continue to both pay and
increase dividends*. Offsetting some of these positives are the continued
contraction of fiscal policy in Washington and a recessionary Europe.

The Federal Reserve's aggressive monetary policy has driven Treasury yields to
generational lows and supported investments in all financial assets, including
equities and high-yield corporate bonds. For example, the Standard & Poor's 500
Index (the S&P 500), a broad measure of the U.S. stock market, returned 15.99%
for the full calendar year ended December 31, 2012, and the Bank of America
Merrill Lynch High Yield Master II Index (the High Yield Index), which measures
the performance of high-yield corporate bonds, returned 15.59% for the same
12-month period. On the other hand, the Barclays Aggregate Bond Index (the
Aggregate Index), which tracks the performance of a higher-quality bond
universe, gained 4.22% for the 12 months ended December 31, 2012; the
safer-still Barclays Government Credit Index (the Government/Credit Index)
returned 4.82%; and 3-month Treasury bills, generally regarded as essentially
"risk free" by the markets, returned just 0.09% in 2012. "Risky" assets
outperformed again in the first quarter of 2013, as the S&P 500 returned 10.60%
and the High Yield Index returned 2.89%. In contrast, the Aggregate Index
returned -0.12% in the first quarter, the Government Credit Index returned
-0.16%, and Treasury bills returned 0.02%.

Despite generally improving economic conditions and a rising stock market,
global economies and investors still face daunting challenges as 2013 moves
forward, although we remain cautiously optimistic. U.S. fiscal policy remains
unsettled, and we feel the U.S. government could be at risk of credit rating
downgrades from one or more of the major ratings agencies if the uncertainties
persist. The Federal Reserve continues to provide extraordinary support to the
U.S. economy and the bond market, but will not do so indefinitely. Europe has
made progress, but has not yet resolved its sovereign-debt/banking problem, nor
has the region been able to exit recession. Japan recently has unveiled

aggressive and unconventional monetary and fiscal policies, but the country
continues to face issues such as high levels of debt as well as an aging
population. China and other emerging economies, while generally in better
shape than most "developed" markets, also face a range of challenges.

While most of the risks outlined here are widely recognized and may already be
"priced in" to the market, we believe investors should continue to expect market
volatility.

At Pioneer, we have long advocated the benefits of staying diversified and
investing for the long term. And while diversification does not assure a profit
or protect against loss in a declining market, we believe there are still
opportunities for prudent investors to earn attractive returns. Our advice, as
always, is to work closely with a trusted financial advisor to discuss your
goals and work together to develop an investment strategy that meets your
individual needs, keeping in mind that there is no single best strategy that
works for every investor.

Pioneer's investment teams have, since 1928, sought out attractive opportunities
in global equity and bond markets, using in-depth research to identify
undervalued individual securities, and using thoughtful risk management to
construct portfolios which balance potential risks and reward in an
ever-changing world.

We encourage you to learn more about Pioneer and our time-tested approach to
investing by consulting with your financial advisor or visiting us online at
us.pioneerinvestments.com. We greatly appreciate your trust in us, and we thank
you for investing with Pioneer.

Sincerely,

               Pioneer Diversified High Income Trust | Annual Report | 4/30/13 3


Portfolio Management Discussion | 4/30/13

Lower-quality, higher-yielding fixed-income securities performed well throughout
the world during the 12-month period ended April 30, 2013, as investors gained
more confidence about the strength of the global economic recovery. In the
following interview, Andrew Feltus discusses the factors that affected the
performance of Pioneer Diversified High Income Trust during the 12-month period.
A senior vice president and portfolio manager at Pioneer, Mr. Feltus is
responsible for the day-to-day management of the Trust.

Q   How did Pioneer Diversified High Income Trust perform during the 12-month
    period ended April 30, 2013?

A   Pioneer Diversified High Income Trust returned 17.38% at net asset value and
    19.98% at market price during the 12-month period ended April 30, 2013.
    During the same period, the Trust's custom benchmark returned 11.59%. The
    custom benchmark is based on equal weightings of the Bank of America Merrill
    Lynch (BofA ML) Global High Yield and Emerging Markets Plus Index, which
    returned 14.95% during the 12-month period, and the Credit Suisse Leveraged
    Loan Index, which returned 8.23%. Unlike the Trust, the custom benchmark
    does not use leverage. While use of leverage increases investment
    opportunity, it also increases investment risk. In addition, during the same
    12-month period, the average return (at market price) of the 40 closed-end
    funds in Lipper's High Current Yield Closed End Funds category (which may or
    may not be leveraged) was 14.55%.

    The shares of the Trust were selling at a 5.4% premium to net asset value at
    the end of the 12-month period on April 30, 2013.

    On April 30, 2013, the standardized 30-day SEC yield on the Trust's shares
    was 8.79%.

Q   How would you describe the investment environment during the 12-month period
    ended April 30, 2013?

A   Credit-sensitive securities performed strongly during the period, led by
    U.S. high-yield bonds and emerging market debt, as worries about debt
    problems in Europe and weakening economic growth in China subsided and the
    markets grew more confident that economies around the world would improve.
    The growing confidence, in turn, led to underperformance by U.S. Treasuries
    and other higher-quality, but lower-yielding investments.

    The period actually got off to a slow start in the spring and early summer
    of 2012, as several problem areas concerned investors. They included
    evidence of weakness in the U.S. economy, slowing economic growth in China
    and the continuing government-debt crisis in Europe. Credit-sensitive
    securities

4 Pioneer Diversified High Income Trust | Annual Report | 4/30/13


    underperformed for most of the summer of 2012, but market sentiment began to
    improve in August when the new leader of the European Central Bank (ECB)
    declared that the bank would do "whatever it takes" to protect the European
    Union and the euro currency. Subsequent to the ECB's announcement, the U.S.
    Federal Reserve System (the Fed) announced its third round of quantitative
    easing through the purchasing of mortgage-backed securities in the open
    market. Additionally, Chinese officials announced that they, too, were
    lowering short-term interest rates and easing credit conditions.

    The actions of the central banks and other governmental authorities helped
    trigger a sharp rally in the financial markets, and high-yield and other
    credit-sensitive securities performed well in the months that followed.

    Strong growth trends in select emerging markets added to the rally, and,
    although global economic data was somewhat mixed during the first quarter of
    2013, the markets took encouragement from the election results in Japan,
    which brought new leadership that favored more aggressive economic stimulus
    through government and central bank intervention. The policies included a
    more accommodative monetary stance by the Bank of Japan, to which a new
    governor was appointed.

    In the United States, meanwhile, progress in the manufacturing and housing
    sectors strengthened investors' confidence. While the markets did not appear
    to worry about how disagreements over the country's fiscal policy could
    affect the U.S. economy, temporary measures agreed upon by Congress and the
    President calmed fears enough to allow the rally in credit-sensitive
    securities to continue through the end of the 12-month period. In addition,
    investors appeared to take comfort from signs of increased fiscal
    consolidation by the U.S. government at a time when the private sector
    appeared to be strengthening.

Q   What types of investments or strategies had the biggest impact on the
    Trust's performance during the 12-month period ended April 30, 2013?

A   The Trust's exposure to higher-yielding investments, including U.S. and
    foreign high-yield corporate bonds as well as select emerging market
    securities, helped drive performance during the 12-month period. Meanwhile
    the Trust's use of leverage, or borrowed funds, magnified the positive
    benefits of a rising market for credit-sensitive securities. While the Trust
    held just a small position in non-U.S. currencies at the end of the 12-month
    period, exposures to the currencies of Mexico, Russia, and higher-yielding
    emerging market nations such as Nigeria and Ghana had a positive influence
    on performance. For diversification purposes and to help protect the Trust's
    portfolio against the risk of rising interest rates, the Trust also had
    healthy allocations to floating-rate, credit-linked securities, including
    bank loans and event-linked ("catastrophe") bonds issued by
    property-and-casualty

               Pioneer Diversified High Income Trust | Annual Report | 4/30/13 5


    insurers. While the floating-rate investments did not help the Trust's
    benchmark-relative performance, as they lagged the returns generated by
    high-yield corporates, the investments still produced solid, positive
    results and contributed to the Trust's absolute performance. While both bank
    loans and catastrophe bonds benefited from strong demand and positive asset
    flows for most of the 12-month period, each asset class faced its own
    challenges. The performance of bank loans was affected when many loans were
    refinanced at lower interest rates, while catastrophe bonds experienced
    periods of price declines, most notably following the ravages inflicted by
    "Superstorm Sandy" along the U.S. eastern seaboard in October 2012.

    At the end of the period, on April 30, 2013, roughly 33% of the Trust's
    total investment portfolio was allocated to U.S. high-yield corporate bonds.
    In addition, nearly 19% of the Trust's total investment portfolio was
    invested in floating-rate bank loans, and 17% of the Trust's total
    investment portfolio was allocated to catastrophe bonds. The Trust also had
    a combined 22% of its total investment portfolio allocated to international
    high-yield debt from developed nations as well as debt from the emerging
    markets.

Q   Which individual investments had the biggest effects on the Trust's
    performance during the 12-month period ended April 30, 2013?

A   The Trust realized good performance from many investments in both U.S.
    high-yield and emerging market high-yield debt.

    Burger King, the fast-food chain, launched an initial public stock offering
    (IPO) near the end of the 12-month period, and the restructuring resulted in
    healthy appreciation of the Trust's holdings of high-yield Burger King
    bonds. Fage, a yogurt company with operations in both the United States and
    Greece, issued new debt and improved its financial structure during the
    period, resulting in gains in the price of the existing debt held in the
    Trust's portfolio. The Trust's holdings of the high-yield debt of Mirabela
    Nickel, a materials company, also gained in value as the company expanded
    its mining operations. In the emerging markets, the Trust enjoyed
    particularly strong performance from holdings of bonds of two Brazilian beef
    companies: Minerva and Marfrig. Earnings of both companies grew as the price
    of beef rose and exports increased.

    Another contributor to the Trust's performance during the period was a bank
    loan to Medical Card Systems, a health care services company operating in
    Puerto Rico. The value of the loans appreciated as the company improved its
    earnings after going through some earlier struggles.

    There were some underperforming holdings held by the Trust during the
    period, including the bonds of James River Coal, which declined in value as
    demand for coal weakened. The continued poor environment in the construction
    industry affected the Trust's holdings of New Enterprise Stone,

6 Pioneer Diversified High Income Trust | Annual Report | 4/30/13


    which supplies aggregate materials for building projects. The company's
    problems were aggravated when it was late in releasing its financial
    reports. However, New Enterprise has appointed a new chief financial
    officer, and we continue to have confidence in the underlying fundamental
    value of the company's assets. The Trust's holdings of the bonds of CEVA, a
    logistics and shipping company with significant exposure to Europe, also
    underperformed during the fiscal year ended April 30, 2013. However, we have
    become more encouraged since the company restructured its finances late in
    the 12-month period and issued new subordinated debt. In the emerging
    markets, holdings of Mexican home-builders Urbi and Homex both detracted
    from the Trust's results as their business models were affected by new
    government housing policies.

    The Trust's disappointing investments also included one bank loan to
    Lodgenet, a U.S. company that provides video and internet services to the
    hotel industry. Lodgenet's operating results were hurt by the effects of
    growing use of new communications technologies, including tablets and smart
    phones, which have reduced demand for traditional hotel communication
    services.

Q   Did the use of derivatives affect the Trust performance during the 12-month
    ended April 30, 2013?

A   The Trust did invest in currency forward contracts to reduce the risks posed
    by changes in the relative values of different currencies. The use of those
    derivatives had a minimal impact on performance.

Q   How did the level of leverage in the Trust change during the 12-month period
    ended April 30, 2013?

A   At the end of the 12-month period on April 30, 2013, the 28.7% of the
    Trust's total managed assets were financed by leverage, compared with 30.0%
    of the Trust's total managed assets financed by leverage at the start of the
    fiscal year on May 1, 2012. The decrease was due to an increase in the value
    of securities in which the Trust had invested.

Q   What is your investment outlook?

A   We believe global economies will continue to grow, although at modest pace,
    allowing the world's major central banks, including the Fed, to maintain
    their accommodative, low-interest-rate policies. That should create a good
    environment for credit-sensitive securities, in particular. Our outlook is
    not so optimistic for very high-quality, lower-yielding government
    securities, including U.S. Treasuries. Their prices appear high, and they
    are realizing negative yields when inflation is taken into consideration
    ("real yields"). If market interest rates rise, Treasury values will suffer
    and potentially affect other sectors of the bond market.

               Pioneer Diversified High Income Trust | Annual Report | 4/30/13 7


    To help mitigate the risks of rising interest rates, we have added to the
    Trust's positions in floating-rate investments, including bank loans,
    catastrophe bonds and floating-rate bonds. Floating-rate investments offer
    the potential for rising yields as interest rates go up. Moreover, bank
    loans offer the additional protection of being senior to other fixed-income
    securities in the debt structure, and so holders of bank loans typically
    would be the first to be paid in any corporate bankruptcy or debt
    restructuring.

    In addition to corporate debt, we also expect to look for additional
    opportunities in some emerging market currencies, where values look
    appealing. We intend to keep the Trust's portfolio well diversified* across
    different sectors.

    Going forward, we think individual security selection is likely to become
    even more important to generating solid performance in the fixed-income
    market. We believe that should play to Pioneer's strengths, as we place
    great emphasis on the analysis of the business fundamentals and
    credit-worthiness of individual companies.

Please refer to the Schedule of Investments on pages 13-44 for a full listing of
Trust securities.

    declining market.

8 Pioneer Diversified High Income Trust | Annual Report | 4/30/13


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.

Investing in foreign and/or emerging markets securities involves risks relating
to interest rates, currency exchange rates, economic, and political conditions.

When interest rates rise, the prices of debt securities in the Trust will
generally fall. Conversely, when interest rates fall the prices of debt
securities in the Trust generally will rise. 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 may invest up to 50% of its total assets in illiquid securities.
Illiquid securities may be difficult to dispose of at a fair price at the times
when the Trust believes it is desirable to do so and their market price is
generally more volatile than that of more liquid securities. Illiquid securities
also are more difficult to value, and investment of the Trust's assets in
illiquid securities may restrict the Trust's ability to take advantage of market
opportunities.

The Trust is authorized to borrow from banks and issue debt securities, which
are forms of leverage. Leverage creates significant risks, including the risk
that the Trust's incremental income or capital appreciation will not be
sufficient to cover the cost of leverage, which may adversely affect the return
for shareholders.

Risks of investing in the Trust are discussed in greater detail in the Trust's
original offering prospectus and in shareowner reports issued from time to time.

These risks may increase share price volatility.

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

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

Call 1-800-225-6292 or visit us.pioneerinvestments.com for the most recent
month-end performance results. Current performance may be lower or higher than
the performance data quoted.

Performance data shown represents past performance. Past performance is no
guarantee of future results. Investment return and market price will fluctuate,
and your shares may trade below NAV due to such factors as interest rate changes
and the perceived credit quality of borrowers.

Total investment return does not reflect broker sales charges or commissions.
All performance is for common shares of the Trust.

Closed-end funds, unlike open-end funds, are not continuously offered. There is
a one-time public offering and, once issued, shares of closed-end funds are sold
in the open market through a stock exchange and frequently trade at prices lower
than their NAV. NAV per common share is total assets less total liabilities,
which includes bank borrowing, divided by the number of common shares
outstanding.

When NAV is lower than market price, dividends are assumed to be reinvested at
the greater of NAV or 95% of the market price. When NAV is higher, dividends are
assumed to be reinvested at prices obtained under the Trust's dividend
reinvestment plan.

The performance table and graph do not reflect the deduction of fees and taxes
that a shareowner would pay on Trust distributions.

The BofA ML Global High Yield and Emerging Markets Plus Index is an unmanaged
index that tracks the performance of the below-and border-line investment-grade
global debt markets denominated in the major developed market currencies. The
Index includes sovereign issuers rated BBB1 and lower along with corporate
issues rated BB1 and lower. There are no restrictions on issuer country of
domicile. The CS Leveraged Loan Index is unmanaged and is designed to mirror the
investible universe of the U.S. dollar-denominated leveraged loan market. The
CS Leveraged Loan Index consists of tradable term loans with at least one year
to maturity and rated BBB or lower.

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. It is not possible to invest directly in an
index.

Notes to Financial Statements | 4/30/13

1. Organization and Significant Accounting Policies

Pioneer Diversified High Income Trust (the Trust) was organized as a Delaware
statutory trust on January 30, 2007. Prior to commencing operations on May 30,
2007, 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 provide a high level of current income and the
Trust may, as a secondary objective, also seek capital appreciation to the
extent that it is consistent with its investment objective.

The Trust's financial statements have been prepared in conformity with U.S.
generally accepted accounting principles that require the management of the
Trust to, among other things, make estimates and assumptions that affect the
reported amounts of assets and liabilities, the disclosure of contingent assets
and liabilities at the date of the financial statements, and the reported
amounts of income, expenses and gain or loss on investments during the reporting
year. Actual results could differ from those estimates.

The following is a summary of significant accounting policies followed by the
Trust in the preparation of its financial statements, which are consistent with
those policies generally accepted in the investment company industry:

A.  Security Valuation

    Security transactions are recorded as of trade date. Investments in loan
    interests are valued in accordance with guidelines established by the Board
    of Trustees at the mean between the last available bid and asked prices from
    one or more brokers or dealers as obtained from Loan Pricing Corporation.
    Senior floating rate loan interests (senior loans) for which no reliable
    price quotes are available will be valued by Loan Pricing Corporation
    through the use of pricing matrices to determine valuations. Fixed income
    securities with remaining maturities of more than sixty days are valued at
    prices supplied by independent pricing services, which consider such factors
    as market prices, market events, quotations from one or more brokers,
    Treasury spreads, yields, maturities and ratings. Valuations may be
    supplemented by dealers and other sources, as required. Equity securities
    that have traded on an exchange are valued at the last sale price on the
    principal exchange where they are traded. Equity securities that have not
    traded on the date of valuation or securities for which sale prices are not
    available, generally are valued using the mean between the last bid and
    asked prices. Short-term fixed income securities with remaining maturities
    of sixty days or less generally are valued at amortized cost. Shares of
    money market mutual funds are valued at such funds' net asset value.

              Pioneer Diversified High Income Trust | Annual Report | 4/30/13 51


    Trading in foreign securities is substantially completed each day at various
    times prior to the close of the New York Stock Exchange ("NYSE"). The values
    of such securities used in computing the net asset value of the Trust's
    shares are determined as of such times.

    Securities or loans interests for which market prices and/or quotations are
    not readily available or are considered to be unreliable are valued by or at
    the direction or with the approval of the Valuation Committee using fair
    value methods pursuant to procedures adopted by the Board of Trustees. The
    Valuation Committee is comprised of certain members of the Board of
    Trustees. The Trust may use fair value methods if it is determined that a
    significant event has occurred after the close of the exchange or market on
    which the security trades and prior to the determination of the Trust's net
    asset value. 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 from exchange prices and such differences could be material. Pioneer
    Investment Management, Inc. (PIM) 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.

    At April 30, 2013, one security was valued using fair value methods (in
    addition to four securities valued using prices supplied by independent
    pricing services) representing 5.7% of net assets. Inputs used when applying
    fair value methods to value a security may include credit ratings, the
    financial condition of the company, current market conditions and comparable
    securities.

    Discounts and premiums on 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 income, including interest or income bearing cash accounts, is
    recorded on an accrual basis, net of unrecoverable foreign taxes withheld at
    the applicable country rates.

    Dividend income is recorded on the ex-dividend date, except that certain
    dividends from foreign securities where the ex-dividend date may have passed
    are recorded as soon as the Trust becomes aware of the ex-dividend data in
    the exercise of reasonable diligence. Gains and losses on sales of
    investments are calculated on the identified cost method for both financial
    reporting and federal income tax purposes.

52 Pioneer Diversified High Income Trust | Annual Report | 4/30/13


B.  Foreign Currency Translation

    The books and records of the Trust are maintained in U.S. dollars. Amounts
    denominated in foreign currencies are translated into U.S. dollars using
    current exchange rates.

    Net realized gains and losses on foreign currency transactions, if any,
    represent, among other things, the net realized gains and losses on foreign
    currency contracts, disposition of foreign currencies and the difference
    between the amount of income accrued and the U.S. dollars actually received.
    Further, the effects of changes in foreign currency exchange rates on
    investments are not segregated in the Statement of Operations from the
    effects of changes in market prices of those securities but are included
    with the net realized and unrealized gain or loss on investments.

C.  Forward Foreign Currency Contracts

    The Trust may enter into forward foreign currency contracts (contracts) for
    the purchase or sale of a specific foreign currency at a fixed price on a
    future date. All contracts are marked to market daily at the applicable
    exchange rates, and any resulting unrealized gains or losses are recorded in
    the Trust's financial statements. The Trust records realized gains and
    losses at the time a portfolio hedge is offset by entry into a closing
    transaction or extinguished by delivery of the currency. Risks may arise
    upon entering into these contracts from the potential inability of
    counterparties to meet the terms of the contracts and from unanticipated
    movements in the value of foreign currencies relative to the U.S. dollar
    (see Note 5).

D.  Federal Income Taxes

    It is the Trust's policy to comply with the requirements of the Internal
    Revenue Code applicable to regulated investment companies and to distribute
    all of its taxable income and net realized capital gains, if any, to its
    shareowners. Therefore, no federal income tax provision is required. As of
    April 30, 2013, the Fund did not have any interest and penalties related to
    uncertain tax positions, which, if applicable, would be recorded as an
    income tax expense on Statement of Operations.Tax years for the prior three
    fiscal 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. generally accepted accounting principles.
    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 classification 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. At
    April 30, 2013,

              Pioneer Diversified High Income Trust | Annual Report | 4/30/13 53


    the Trust reclassified $488,962 to decrease undistributed net investment
    income, $490,275 to decrease accumulated net realized loss on investments
    and foreign currency transactions and $1,313 to decrease paid-in capital to
    reflect permanent book/tax differences. The reclassification has no impact
    on the net assets of the Trust and presents the Trust's capital accounts on
    a tax basis.

    At April 30, 2013, the Trust was permitted to carry forward $595,129 of
    short-term losses and $2,699,624 of long term losses under the Regulated
    Investment Company Modernization Act of 2010 without limitation.
    Additionally, at April 30, 2013, the Trust had a net capital loss carry
    forward of $23,843,173 of which the following amounts will expire between
    2016 and 2019 if not utilized: $231,744 in 2016, $413,150 in 2017,
    $21,948,862 in 2018, and $1,249,417 in 2019. Since unlimited losses are
    required to be utilized prior to losses incurred in pre-enactment years,
    pre-enactment capital loss carryforwards may be more likely to expire
    unused.

    The tax character of current year distributions payable to shareowners
    during the years ended April 30, 2013 and April 30, 2012 was as follows:

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

    The difference between book-basis and tax-basis unrealized appreciation is
    primarily attributable to the tax deferral of losses on wash sales, the
    realization for tax purposes of unrealized gains on investments in passive
    foreign investment companies, the book/tax differences in the accrual of
    income on securities in default, the difference between book and tax
    amortization methods for premiums and discounts on fixed income
    securities and other temporary book/tax differences.

E.  Risks

    Information regarding the Trust's principal risks is contained in the
    Trust's original offering prospectus, with additional information included
    in the Trust's shareowner reports issued from time to time. Please refer to
    those documents when considering the Trust's principal risks. At times, the
    Trust's investments may represent industries or industry sectors that are
    interrelated or have common risks, making the Trust more susceptible to any
    economic, political, or regulatory developments or other risks affecting
    those industries and sectors.

    The Trust invests in below investment grade (high yield) debt securities,
    floating rate loans and event-linked bonds sometimes referred to as
    "catastrophe" bonds or "insurance-linked" bonds. The Trust may invest in
    securities and other obligations of any credit quality, including those that
    are rated below investment grade, or are unrated but are determined by the
    investment adviser to be of equivalent credit quality. Below investment
    grade securities are commonly referred to as "junk bonds" and are considered
    speculative with respect to the issuer's capacity to pay interest and repay
    principal. These securities involve greater risk of loss, are subject to
    greater price volatility, and are less liquid, especially during periods of
    economic uncertainty or change, than higher rated debt securities. The Trust
    may invest in securities of issuers that are in default or that are in
    bankruptcy.

    The Trust's investments in certain foreign markets or countries with limited
    developing markets may subject the Trust to a greater degree of risk than
    would investments in a developed market. These risks include disruptive
    political or economic conditions and the possible imposition of adverse
    governmental laws or currency exchange restrictions.

F.  Repurchase Agreements

    With respect to repurchase agreements entered into by the Trust, the value
    of the underlying securities (collateral), including accrued interest, is
    required to be equal to or in excess of the repurchase price. The collateral
    for all repurchase agreements is held in safekeeping in the customer-only
    account of the Trust's custodian or a subcustodian of the Trust. The Trust's
    investment adviser, Pioneer Investment Management, Inc. (PIM), is
    responsible for determining that the value of the collateral remains at
    least equal to the repurchase price.

G.  Automatic Dividend Reinvestment Plan

    All common shareowners whose shares are registered in their own names
    automatically participate in the Automatic Dividend Reinvestment Plan (the
    Plan), under which participants receive all dividends and capital gain
    distributions (collectively, dividends) in full and fractional common shares
    of the Trust in lieu of cash. Shareowners may elect not to participate in
    the Plan. Shareowners not participating in the Plan receive all dividends
    and capital

              Pioneer Diversified High Income Trust | Annual Report | 4/30/13 55


    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 common shares of
    the Trust on terms that differ from the terms of the Plan.

    Whenever the Trust declares a dividend on common shares payable in cash,
    participants in the Plan will receive the equivalent in common shares
    acquired by the Plan Agent either (i) through receipt of additional unissued
    but authorized common shares from the Trust or (ii) by purchase of
    outstanding common shares on the New York Stock Exchange or elsewhere. If,
    on the payment date for any dividend, the net asset value per common share
    is equal to or less than the market price per share plus estimated brokerage
    trading fees (market premium), the Plan Agent will invest the dividend
    amount in newly issued common shares. The number of newly issued common
    shares to be credited to each account will be determined by dividing the
    dollar amount of the dividend by the net asset value per common share on the
    date the shares are issued, provided that the maximum discount from the then
    current market price per share on the date of issuance does not exceed 5%.
    If, on the payment date for any dividend, the net asset value per common
    share is greater than the market value (market discount), the Plan Agent
    will invest the dividend amount in common shares acquired in open-market
    purchases. There are no brokerage charges with respect to newly issued
    common shares. However, each participant will pay a pro rata share of
    brokerage trading fees incurred with respect to the Plan Agent's open-market
    purchases. Participating in the Plan does not relieve shareowners from any
    federal, state or local taxes which may be due on dividends paid in any
    taxable year. Shareowners holding Plan shares in a brokerage account may not
    be able to transfer the shares to another broker and continue to participate
    in the Plan.

2.  Management Agreement

    PIM, a wholly owned indirect subsidiary of UniCredit S.p.A. (UniCredit),
    manages the Trust's portfolio. Management fees payable under the Trust's
    Advisory Agreement with PIM are calculated daily at the annual rate of 0.85%
    of the Trust's average daily managed assets. "Managed assets" means (a) the

56 Pioneer Diversified High Income Trust | Annual Report | 4/30/13


total assets of the Trust, including any form of investment leverage, minus (b)
all accrued liabilities incurred in the normal course of operations, which shall
not include any liabilities or obligations attributable to investment leverage
obtained through (i) indebtedness of any type (including, without limitation,
borrowing through a credit facility of the issuance of debt securities), (ii)
the issuance of preferred stock or other similar preference securities, and/or
(iii) any other means. For the year ended April 30, 2013, the net management fee
was 0.85% of the Trust's average daily managed assets, which was equivalent to
0.60% of the Trust's average daily net assets.

In addition, under PIM's management and administration agreements, certain other
services and costs are paid by PIM and reimbursed by the Trust. At April 30,
2013 $243,628 was payable to PIM related to management costs, administrative
costs and certain other reimbursements and is included in "Due to affiliates"
and "Administration fee" on the Statement of Assets and Liabilities.

Effective May 1, 2012, PIM has retained Brown Brothers Harriman & Co. (BBH) to
provide certain administrative and accounting services to the Trust on its
behalf. For such services, the Trust pays BBH a monthly fee at an annual rate of
0.025% of the Trust's average daily managed assets subject to a minimum monthly
fee of $6,250. Previously, PIM had retained State Street Bank and Trust Company
(State Street) to provide such services. PIM paid State Street a monthly fee at
an annual rate of 0.07% of the Trust's average daily managed assets up to $500
million and 0.03% for average daily managed assets in excess of $500 million,
subject to a minimum monthly fee of $10,000.

3.  Transfer Agents

Pioneer Investment Management Shareholder Services, Inc. (PIMSS), a wholly owned
indirect subsidiary of UniCredit, through a sub-transfer agency agreement with
American Stock Transfer & Trust Company, provides substantially all transfer
agent and shareowner services related to the Trust at negotiated rates.

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

4. Expense Offset Arrangement

The Trust has entered into an arrangement with its custodian whereby credits
realized as a result of uninvested cash balances are used to reduce a portion of
the Trust's custodian expenses. For the year ended April 30, 2013, the Trust
expenses were not reduced under such an arrangement.

              Pioneer Diversified High Income Trust | Annual Report | 4/30/13 57


5. Forward Foreign Currency Contracts

During the year ended April 30, 2013, the Trust entered into various forward
foreign currency contracts that obligate the Trust to deliver or take delivery
of currencies at specified future maturity dates. Alternatively, prior to the
settlement date of a forward foreign currency contract, the Trust may close out
such contract by entering into an offsetting contract. The average value of
contracts open during the year ended April 30, 2013 was $5,351,082. At April 30,
2013, the Trust had no outstanding settlement contracts.

Open portfolio hedges at April 30, 2013, were as follows:

Effective February 3, 2012, the Trust extended the maturity of its existing
Revolving Credit Facility (the Credit Agreement) with the Bank of Nova Scotia;
the amount of the facility remains at $75 million.

58 Pioneer Diversified High Income Trust | Annual Report | 4/30/13


At April 30, 2013, the Trust had a borrowing outstanding under the Credit
Agreement totaling $69,000,000. The interest rate charged at April 30, 2013 was
1.10.%. During the year ended April 30, 2013, the average daily balance was
$69,000,000 at a weighted average interest rate of 1.12%. With respect to the
loan, interest expense of $784,519 is included in the Statement of Operations.

The Trust is required to maintain 300% asset coverage with respect to amounts
outstanding under the Credit Agreement. Asset coverage is calculated by
subtracting the Trust's total liabilities, not including any bank loans and
senior securities, from the Trust's total assets and dividing such amount by the
principal amount of the borrowings outstanding. As of the date indicated below,
the Trust's debt outstanding and asset coverage were as follows:

8. Basis for Consolidation of the Financial Statements

The consolidated financial statements of the Trust as of April 30, 2012 included
the accounts of the Blaze Holding HINCT, Inc. (the "Subsidiary"). All
intercompany accounts and transactions have been eliminated in consolidation.
The Subsidiary, a Delaware corporation, was incorporated on February 10, 2011
and was wholly-owned and controlled by the Trust. The Subsidiary acted as
investment vehicle for the Trust's interest in Blaze Recycling and Metals LLC,
Class A Units (Blaze").

On November 27, 2012, the Subsidiary sold its interest in Blaze, and liquidated
on December 31, 2012. The disposition of this investment resulted in a
recognized loss of $256,250, which is reflected as part of the Net Realized Gain
(Loss) on Investments in the Statement of Operations. The investment in the
Subsidiary had no other impact on the Trust's operations. As a result, the
financial statements as of April 30, 2013 are not consolidated.

9. Trust Shares

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

60 Pioneer Diversified High Income Trust | Annual Report | 4/30/13


Report of Independent Registered Public Accounting Firm

To the Board of Trustees and the Shareowners of
Pioneer Diversified High Income Trust:
--------------------------------------------------------------------------------

We have audited the accompanying statement of assets and liabilities of Pioneer
Diversified High Income Trust (the "Trust"), including the schedule of
investments, as of April 30, 2013, and the related statements of operations and
cash flows for the year then ended, the statements of changes in net assets for
each of the two years in the period then ended and the financial highlights for
each of the five years in the period then ended. These financial statements and
financial highlights are the responsibility of the Trust's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. We were
not engaged to perform an audit of the Trust's internal control over financial
reporting. Our audits included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in the
circumstances, 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. An audit also includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall
financial statement presentation. Our procedures included confirmation of
securities owned as of April 30, 2013, by correspondence with the custodian and
brokers or by other appropriate auditing procedures where replies from brokers
were not received. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of

Approval of Investment Advisory Agreement

Pioneer Investment Management, Inc. (PIM) serves as the investment adviser to
Pioneer Diversified High Income Trust (the Trust) pursuant to an investment
advisory agreement between PIM and the Trust. In order for PIM to remain the
investment adviser of the Trust, the Trustees of the Trust must determine
annually whether to renew the investment advisory agreement for the Trust.

The contract review process began in March 2012 as the Trustees of the Trust
agreed on, among other things, an overall approach and timeline for the process.
In July 2012, the Trustees approved the format of the contract review materials
and submitted their formal request to PIM to furnish information necessary to
evaluate the terms of the investment advisory agreement. The contract review
materials were provided to the Trustees in July 2012 and September 2012. After
reviewing and discussing the materials, the Trustees submitted a request for
additional information to PIM, and materials were provided in response to this
request. Meetings of the Independent Trustees of the Trust were held in July,
September, October, and November, 2012 to review and discuss the contract review
materials. In addition, the Trustees took into account the information related
to the Trust provided to the Trustees at each regularly scheduled meeting.

At a meeting held on November 13, 2012, based on their evaluation of the
information provided by PIM and third parties, the Trustees of the Trust,
including the Independent Trustees voting separately, unanimously approved the
renewal of the investment advisory agreement for another year. In considering
the renewal of the investment advisory agreement, the Trustees considered
various factors that they determined were relevant, including the factors
described below. The Trustees did not identify any single factor as the
controlling factor in determining to approve the renewal of the agreement.

Nature, Extent and Quality of Services

The Trustees considered the nature, extent and quality of the services that had
been provided by PIM to the Trust, taking into account the investment objective
and strategy of the Trust. The Trustees reviewed the terms of the investment
advisory agreement. The Trustees also reviewed PIM's investment approach for the
Trust, its research process and its process for trade execution. The Trustees
considered the resources of PIM and the personnel of PIM who provide investment
management services to the Trust. The Trustees considered the non-investment
resources and personnel of PIM involved in PIM's services to the Trust,
including PIM's compliance and legal resources and personnel.

              Pioneer Diversified High Income Trust | Annual Report | 4/30/13 63


The Trustees also considered the substantial attention and high priority given
by PIM's senior management to the Pioneer fund complex. In addition, the
Trustees considered PIM's plans to increase resources in its investment
management function and other enhancements to PIM's advisory capabilities.

The Trustees considered that PIM supervises and monitors the performance of the
Trust's service providers and provides the Trust with personnel (including Trust
officers) and other resources that are necessary for the Trust's business
management and operations. The Trustees also considered that, as administrator,
PIM is responsible for the administration of the Trust's business and other
affairs. The Trustees considered the fees paid to PIM for the provision of
administration services.

Based on these considerations, the Trustees concluded that the nature, extent
and quality of services that had been provided by PIM to the Trust were
satisfactory and consistent with the terms of the investment advisory agreement.

Performance of the Trust

The Trustees considered the performance results of the Trust over various time
periods. They reviewed information comparing the Trust's performance with the
performance of its peer group of funds as classified by Morningstar, Inc.
(Morningstar), an independent provider of investment company data, and with the
performance of the Trust's benchmark index. The Trustees considered that the
Trust's annualized total return was in the fourth quintile of its Morningstar
category for the one and five year periods ended June 30, 2012, and in the
second quintile of its Morningstar category for the three year period ended June
30, 2012 (In all quintile rankings referred to throughout this disclosure, first
quintile is most favorable to the Trust's shareowners. Thus, highest relative
performance would be first quintile and lowest relative expenses would also be
first quintile.) The Trustees considered that the Trust's twelve month average
gross portfolio yield (using month end 30 day effective yields) exceeded the
twelve month average yield of the Trust's benchmark index. The Trustees also
reviewed data provided by PIM showing how leverage had benefited the Trust's
common shareholders. The Trustees discussed the Trust's performance record. They
indicated that they were satisfied with the discussions with PIM with respect to
the Trust's performance.

Management Fee and Expenses

The Trustees considered information on the fees and expenses of the Trust in
comparison to the management fees and the expense ratios of a peer group of
funds selected on the basis of criteria determined by the Independent Trustees
for this purpose using data provided by Strategic Insight Mutual Fund Research
and Consulting, LLC (Strategic Insight), an independent third party. The
Trustees considered that the Trust's management fee rate (based on

64 Pioneer Diversified High Income Trust | Annual Report | 4/30/13


managed assets) for the twelve months ended June 30, 2012 was in the fifth
quintile relative to the management fees paid by other funds in its Strategic
Insight peer group for the comparable period. The Trustees also considered that
the Trust's expense ratio (based on managed assets) for the twelve months ended
June 30, 2012 was in the fifth quintile relative to its Strategic Insight peer
group for the comparable period. The Trustees noted and discussed reasons that
the Trust's management fee and expense ratio were high relative to the
management fees and expense ratios of other funds in the Trust's Strategic
Insight peer group. The Trustees noted the investment management expertise and
resources required to implement the Trust's investment strategy given the
multiple asset classes in which the Trust invests. The Trustees also considered
that the Trust did not have a clear cut peer group, noting that other funds in
the peer group invested primarily in traditional high yield bonds. The Trustees
considered information presented by PIM regarding management fees paid by two
multi-sector closed-end funds that were launched in 2012, noting that the
Trust's management fee compared favorably to the management fees paid by those
funds.

The Trustees reviewed management fees charged by PIM and PIM's affiliate,
Pioneer Institutional Asset Management, Inc. (together with PIM, "Pioneer") to
institutional and other clients, including publicly offered European funds
sponsored by affiliates of Pioneer, unaffiliated U.S. registered investment
companies (in a sub-advisory capacity), and unaffiliated foreign and domestic
separate accounts. The Trustees also considered PIM's costs in providing
services to the Trust and Pioneer's costs in providing services to the other
clients and considered the differences in management fees and profit margins for
Trust and non-Trust services. In evaluating the fees associated with Pioneer's
client accounts, the Trustees took into account the respective demands,
resources and complexity associated with the Trust and client accounts. The
Trustees noted that in some instances the fee rates for those clients were lower
than the management fee for the Trust and considered that, under the investment
advisory agreement with the Trust, PIM performs additional services for the
Trust that it does not provide to those other clients or services that are
broader in scope, including oversight of the Trust's other service providers and
activities related to compliance and the extensive regulatory and tax regimes to
which the Trust is subject. The Trustees also considered the different
entrepreneurial risks associated with PIM's management of the Trust and
Pioneer's management of the other client accounts. The Trustees concluded that
the management fee payable by the Trust to PIM was reasonable in relation to the
nature and quality of the services provided by PIM.

              Pioneer Diversified High Income Trust | Annual Report | 4/30/13 65


Profitability

The Trustees considered information provided by PIM regarding the profitability
of PIM with respect to the advisory services provided by PIM to the Trust,
including the methodology used by PIM in allocating certain of its costs to the
management of the Trust. The Trustees also considered PIM's profit margin in
connection with the overall operation of the Trust. They further reviewed the
financial results realized by PIM and its affiliates from non-fund businesses.
The Trustees considered PIM's profit margins with respect to the Trust in
comparison to the limited industry data available and noted that the
profitability of any adviser was affected by numerous factors, including its
organizational structure and method for allocating expenses. The Trustees
concluded that PIM's profitability with respect to the management of the Trust
was not unreasonable.

Economies of Scale

The Trustees considered the extent to which PIM may realize economies of scale
or other efficiencies in managing and supporting the Trust. Since the Trust is a
closed-end fund that has not raised additional capital, the Trustees concluded
that economies of scale were not a relevant consideration in the renewal of the
investment advisory agreement.

Other Benefits

The Trustees considered the other benefits to PIM from its relationship with the
Trust. The Trustees considered the character and amount of fees paid by the
Trust, other than under the investment advisory agreement, for services provided
by PIM and its affiliates. The Trustees further considered the revenues and
profitability of PIM's businesses other than the fund business. The Trustees
considered the intangible benefits to PIM by virtue of its relationship with the
Trust and the other Pioneer funds. The Trustees concluded that the receipt of
these benefits was reasonable in the context of the overall relationship between
PIM and the Trust.

Conclusion

After consideration of the factors described above as well as other factors, the
Trustees, including all of the Independent Trustees, concluded that the
investment advisory agreement between PIM and the Trust, including the fees
payable thereunder, was fair and reasonable and voted to approve the proposed
renewal of the investment advisory agreement for the Trust.

a code of ethics that applies to the registrant's principal executive officer,

        relationships;

        (2) Full, fair, accurate, timely, and understandable disclosure in

period covered by the report, to a provision of its code of ethics that applies
to the registrant's principal executive officer, principal financial officer,
principal accounting officer or controller, or persons performing similar
functions, regardless of whether these individuals are employed by the
registrant or a third party, and that relates to any element of the code of
ethics definition enumerated in paragraph (b) of this Item. The registrant must

undertaking to provide its code of ethics to any person without charge, upon
request, pursuant to paragraph (f)(3) of this Item.

(d) If the registrant has, during the period covered by the report, granted a

        or persons performing similar functions, as an exhibit to its annual
        report on this Form N-CSR (see attachment);

        (2) Post the text of such code of ethics on its Internet website and

    (i)  Accept directly or indirectly any consulting, advisory, or other
         compensatory fee from the issuer; or

 PIONEER FUNDS
            APPROVAL OF AUDIT, AUDIT-RELATED, TAX AND OTHER SERVICES
                       PROVIDED BY THE INDEPENDENT AUDITOR

                  SECTION I - POLICY PURPOSE AND APPLICABILITY

The Pioneer Funds recognize the importance of maintaining the independence of
their outside auditors. Maintaining independence is a shared responsibility
involving Pioneer Investment Management, Inc ("PIM"), the audit committee and
the independent auditors.

The Funds recognize that a Fund's independent auditors: 1) possess knowledge of
the Funds, 2) are able to incorporate certain services into the scope of the
audit, thereby avoiding redundant work, cost and disruption of Fund personnel
and processes, and 3) have expertise that has value to the Funds. As a result,
there are situations where it is desirable to use the Fund's independent
auditors for services in addition to the annual audit and where the potential
for conflicts of interests are minimal. Consequently, this policy, which is
intended to comply with Rule 210.2-01(C)(7), sets forth guidelines and
procedures to be followed by the Funds when retaining the independent audit firm
to perform audit, audit-related tax and other services under those
circumstances, while also maintaining independence.

Approval of a service in accordance with this policy for a Fund shall also
constitute approval for any other Fund whose pre-approval is required pursuant
to Rule 210.2-01(c)(7)(ii).

In addition to the procedures set forth in this policy, any non-audit services
that may be provided consistently with Rule 210.2-01 may be approved by the
Audit Committee itself and any pre-approval that may be waived in accordance
with Rule 210.2-01(c)(7)(i)(C) is hereby waived.

Selection of a Fund's independent auditors and their compensation shall be
determined by the Audit Committee and shall not be subject to this policy.

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

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

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


    (2) Disclose the percentage of services described in each of paragraphs (b)
   through (d) of this Item that were approved by the audit committee pursuant
   to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

Non-Audit Services
Beginning with non-audit service contracts entered into on
or after May 6, 2003, the effective date of the new SEC
pre-approval rules, the Trust's audit committee is required
to pre-approve services to affiliates defined by SEC rules
to the extent that the services are determined to have a
direct impact on the operations or financial reporting of the
Trust. For the years ended April 30, 2013 and 2012, there
were no services provided to an affiliate that required the
Trust's audit committee pre-approval.

(f) If greater than 50 percent, disclose the percentage of hours expended on the
principal accountant's engagement to audit the registrant's financial statements
for the most recent fiscal year that were attributed to work performed by
persons other than the principal accountant's full-time, permanent employees.

N/A

(g) Disclose the aggregate non-audit fees billed by the registrant's accountant
for services rendered to the registrant, and rendered to the registrant's
investment adviser (not including any sub-adviser whose role is primarily
portfolio management and is subcontracted with or overseen by another investment
adviser), and any entity controlling, controlled by, or under common control
with the adviser that provides ongoing services to the registrant for each of
the last two fiscal years of the registrant.

The aggregate non-audit fees for the Trust and affiliates, as
previously defined, totaled approximately $8,290 in 2013
and $8,290 in 2012.

(h) Disclose whether the registrant's audit committee of the board of trustees
has considered whether the provision of non-audit services that were rendered to
the registrant's investment adviser (not including any subadviser whose role is
primarily portfolio management and is subcontracted with or overseen by another
investment adviser), and any entity controlling, controlled by, or under common
control with the investment adviser that provides ongoing services to the
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 Trust'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 registrants audit committee as specified in
Section 3(a)(58)(B) of the Exchange Act (15 U.S.C. 78c(a)(58)(B)),
so state.

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)).

(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.

1 of this Form.

Included in Item 1


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

o A portfolio manager could favor one account over another in allocating new
  investment opportunities that have limited supply, such as initial public
  offerings and private placements. If, for example, an initial


                                       0


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

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

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

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

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


COMPENSATION OF PORTFOLIO MANAGERS
Pioneer has adopted a system of compensation for portfolio managers that seeks
to align the financial interests of the portfolio managers with those of
shareholders of the accounts (including Pioneer funds) the portfolio managers
manage, as well as with the financial performance of Pioneer. The compensation


                                       1


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

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

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

o PIONEER RESULTS AND BUSINESS LINE RESULTS. Pioneer's financial performance,
  as well as the investment performance of its investment management group,
  affect a portfolio manager's actual bonus by a leverage factor of plus or
  minus (+/-) a predetermined percentage.

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

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

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

Describe any material changes to the procedures by which shareholders

those changes were implemented after the registrant last provided
disclosure in response to the requirements of Item 7(d)(2)(ii)(G)
of Schedule 14A (17 CFR 240.14a-101), or this Item.


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


ITEM 11. CONTROLS AND PROCEDURES.

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

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


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

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

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

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


ITEM 12. EXHIBITS.

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

(a) Any code of ethics, or amendment thereto, that is the subject of the
disclosure required by Item 2, to the extent that the registrant intends to
satisfy the Item 2 requirements through filing of an exhibit.



(b) A separate certification for each principal executive officer and principal
financial officer of the registrant as required by Rule 30a-2 under the Act
(17 CFR 270.30a-2).

Filed herewith.
