President's Letter

Dear Shareowner,

Stock and bond markets around the globe have been experiencing one of their
most tumultuous periods in history. Investors have witnessed volatility of a
magnitude that many have never before seen. Distance often provides the best
vantage point for perspective. Still, we believe that the benefits of basic
investment principles that have stood the test of time -- even in the midst of
market turmoil -- cannot be underestimated.

First, invest for the long term. The founder of Pioneer Investments, Philip L.
Carret, began his investment career during the 1920s. One lesson he learned is
that while great prosperity affords an advantageous time for selling stocks,
extreme economic slumps can create opportunities for purchase. Indeed, many of
our portfolio managers, who follow the value-conscious investing approach of
our founder, are looking at recent market conditions as an opportunity to buy
companies whose shares we believe have been unjustifiably beaten down by
indiscriminate selling, but that we have identified as having strong prospects
over time. While investors may be facing a sustained market downturn, we
continue to believe that patience, along with staying invested in the market,
are important considerations for long-term investors.

A second principle is to stay diversified across different types of
investments. The global scope of the current market weakness poses challenges
for this basic investment axiom. But the turbulence makes now a good time to
reassess your portfolio and make sure that your investments continue to meet
your needs. We believe you should work closely with your financial advisor to
find the mix of stocks, bonds and money market assets that is best aligned to
your particular risk tolerance and investment objective.

As the investment markets sort through the continuing crisis in the financial
industry, we are staying focused on the fundamentals and risk management. With
more than 80 years of experience behind us, we have learned how to navigate
turbulent markets. At Pioneer Investments, risk management has always been a
critical part of our culture -- not just during periods of extraordinary
volatility. Our investment process is based on fundamental research,
quantitative analysis and active portfolio management. This three-pillared
process, which we apply to each of our portfolios, is supported by an
integrated team approach and is designed to carefully balance risk and reward.
While we

2    Pioneer Diversified High Income Trust | Annual Report | 4/30/09


see potential chances for making money in many corners of the market, it takes
research and experience to separate solid investment opportunities from
speculation.

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

Respectfully,

/s/Daniel K. Kingsbury

Portfolio Management Discussion |4/30/09

High-yield bond and bank loan investments struggled through the final eight
months of 2008 in the face of a severe credit crisis before credit-related
securities started to recover early in 2009. In the following discussion,
Andrew Feltus, CFA, and Jonathan Sharkey discuss the factors affecting the
performance of Pioneer Diversified High Income Trust during the 12 months ended
April 30, 2009. Mr. Feltus and Mr. Sharkey are members of Pioneer's Fixed
Income Department and leaders of the investment team responsible for the daily
management of the Trust.

Q    How did the Trust perform during the 12 months ended April 30, 2009?

A    Pioneer Diversified High Income Trust had a total return of -24.69% at net
     asset value and a return of -23.11% at market price. As of April 30, 2009,
     the Trust was selling at a discount of market price to net asset value of
     -5.1%. Over the same period, the Trust's benchmark returned -14.78%. The
     benchmark's return is based on a 50% weighting of the Merrill Lynch Global
     High Yield and Emerging Market Plus Index (these indices are not leveraged)
     and a 50% weighting of the CSFB Leveraged Loan Index, which produced total
     returns of -14.23% and -15.32%, respectively. The Trust's 30-day SEC yield
     was 10.68% and the distribution rate based on market close on April 30,
     2009, was 17.23%, based on the most recent monthly dividend.

Q    What were the principal factors affecting the Trust's performance during
     the 12 months ended April 30, 2009?

A    After a brief market rally in the early spring of 2008, the value of
     high-yield bond and bank-loan investments declined sharply over the
     remainder of the year in the face of mounting credit problems. The
     volatility in fixed-income markets peaked in late 2008 following the
     September bankruptcy of investment bank Lehman Brothers and the collapse or
     near-collapse of several other institutions, several of which required U.S.
     government assistance to survive. Market values for fixed-income securities
     exposed to credit risk plummeted in the fourth quarter of 2008, finishing a
     dismal year for such investments. However, early in 2009 investors started
     perceiving attractive values relative to the risks in investments such as
     high-yield bonds and floating-rate loans securities, leading to a rebound
     in those markets in the final months of the Trust's fiscal year.

     In this environment, the Trust's allocation to catastrophe-linked bonds
     helped support performance results. Catastrophe-linked bonds are
     reinsurance securities issued against the possibility of significant losses
     incurred by

4    Pioneer Diversified High Income Trust | Annual Report | 4/30/09


     casualty insurers from natural catastrophes, such as earthquakes or storms.
     Bank loans did not hold up as well, as mounting questions about credit
     problems caused institutional investors such as hedge funds to sell-off
     their bank loan investments. The Trust's overweight position in U.S.
     high-yield corporate bonds also performed poorly, as they underperformed
     some other high-yield sectors, notably emerging-market sovereign
     securities. However, the decision to reduce the Trust's exposure to foreign
     currencies tended to help results, as did the decision to avoid, for most
     of the period, commercial mortgage-backed debt. As noted, the Trust's
     bank-loan investments also struggled, as an emphasis on B-rated and a
     de-emphasis on BB-rated securities tended to hold back results when
     lower-rated investments underperformed. The Trust's performance at net
     asset value ("NAV") lagged the overall market indices for the period,
     partially due to the effects of the Trust's use of leverage (borrowed
     funds) in the market. While leverage tends to amplify gains in bull
     markets, it also tends to magnify losses in poor markets. At the end of the
     fiscal year, the Trust's leverage ratio was 25%. The percentage of leverage
     stayed relatively unchanged for the year.

     At the end of the 12-month period, bank loans represented 31.6% of the
     Trust's investment portfolio, while U.S. high-yield corporates accounted
     for 28.9% of the Trust's investment portfolio, and emerging market and
     international high-yield bonds represented 12% of the Trust's investment
     portfolio. Catastrophe-linked bonds accounted for 19.5% of the Trust's
     investment portfolio.

Q    What were some of the investments that supported the Trust's performance
     during the 12 months ended April 30, 2009?

A    The Trust's position in high-yield bonds of Talecris did well. The health
     care company, which specializes in processing blood supplies, announced it
     was to be acquired by another company. Bonds of electric utility Jamaica
     Mirant helped performance, as did several securities tied to the
     telecommunication service sector. Also supporting the Trust's results were
     a loan to Stratos Global, which provides voice and data communication
     services to corporations and government agencies; GCI, another
     telecommunication service provider; and bonds of Intelsat, a satellite
     communications company. In addition, a loan to Metavante, which provides
     transaction-processing services to the banking industry, helped the Trust's
     performance.

Q    What were some of the investments that produced disappointing results for
     the Trust over the 12 months ended April 30, 2009?

A    Loans to steel companies, such as Aloma Steel and Niagara Steel, which
     fared poorly in a difficult year for the metals industry, was one area that
     hurt the Trust's results over the 12-month period. Also holding back
     results were loans to Ceva Group, a logistics company servicing the
     automotive industry. High-yield bonds performed poorly as a group,
     especially those of

            Pioneer Diversified High Income Trust | Annual Report | 4/30/09    5


     commodity related corporations. Bonds of Aventine Renewable Energy
     Resources, an ethanol producer, lost most of their value when the company
     defaulted. The Trust's overweight position in chemical industry bonds also
     proved to be a detractor, with poor performance by bonds of ARCO, Georgia
     Gulf, Ineos and Kronos Worldwide.

Q    What is your investment outlook?

A    We think domestic high-yield corporate bonds have fallen to reflect a
     depression-style scenario, which we think is a worse outlook than is
     justified. As a consequence, we believe investors will continue to see
     value in high-yield bonds, which we believe are priced below their
     fundamental value. We think 2009 should show improvement in market
     conditions and believe that the Trust is well positioned to participate in
     a market rebound. However, we also can anticipate continued volatility in
     day-to-day trading.

     Although they suffered minor collateral damage from the credit crunch,
     catastrophe-linked bonds have proven to be an island of calm within the
     high-yield markets. Their recent history supports the theory that the
     performance of this group is not highly correlated to other areas in the
     high-yield market. At current yields, we believe catastrophe-linked bonds
     are priced comparable to high-yield bonds and bank loans, and we see
     opportunities in the coming months, as new supply is expected to be low. We
     believe the best values are in U.S. hurricane bonds.

     Bank loans, as an asset class, still face fundamental issues, especially in
     light of our projections that the economy is likely to contract for the
     second quarter of 2009 -- on the heels of the large contraction seen in the
     first quarter of the year -- before starting to recover in the final two
     quarters. We also expect that unemployment will remain high. On the plus
     side, the market's advance in early 2009 does offer evidence that many
     companies now can get financing, while the recovery value of loans in
     bankruptcy may improve. The market also has shown signs of stabilization as
     buyers have stepped in to make investments. Liquidity has improved in the
     market and refinancing activity has increased, raising the potential for
     price appreciation by bank loans. At the same time, the new-issue market
     may begin to reopen.

     Loans have continued to sell at very attractive discounts and we believe
     the bank loan market may continue to perform well, although we cannot
     predict when values will snap back significantly.

Please refer to the Schedule of Investments on pages 11-32 for a full listing
of Trust securities.

6    Pioneer Diversified High Income Trust | Annual Report | 4/30/09


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 fixed-income securities in the Trust
will generally fall. Conversely, when interest rates fall the prices of
fixed-income securities in the Trust generally will rise. Investments in the
Trust are subject to possible loss due to the financial failure of underlying
securities and their inability to meet their debt obligations.

The Trust may invest significantly 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 income or capital appreciation will not be sufficient to cover
the cost of leverage, which may adversely affect the return for the holders of
common shares.

Risks of investing in the Trust are discussed in greater detail in the Trust's
original offering prospectus relating to its common shares.

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

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

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

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

Closed-end funds, unlike open-end funds, are not continuously offered. There is
a one-time public offering and, once issued, shares of closed-end funds are
sold in the open market through a stock exchange and frequently trade at prices
lower than their NAV. NAV per common share is total assets less total
liabilities, which includes 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 Merrill Lynch Global High Yield and Emerging Markets Plus Index 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 CSFB
Leveraged Loan Index is designed to mirror the investible universe of the U.S.
dollar-denominated leveraged loan market. The CSFB 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 are not leveraged. You cannot invest directly in an index.

Notes to Financial Statements | 4/30/09

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, and
the sale and issuance to Pioneer Investment Management, Inc. (PIM), the Trust's
investment adviser, a wholly owned indirect subsidiary of UniCredit S.p.A.
(UniCredit), of 4,188 shares of beneficial interest at an aggregate purchase
price of $100,000. PIM reimbursed all the Trust's organizational expenses and
paid the amount by which the aggregate offering costs (other than the sales
load) exceeded $0.05 per share of the common share offering. The investment
objective of the Trust is to provide a high level of current income and, as a
secondary objective, the Trust may seek capital appreciation to the extent that
it is consistent with its investment objective.

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 in a
developed market. These risks include disruptive political or economic
conditions and the possible imposition of adverse governmental laws or currency
exchange restrictions.

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

The Trust 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

38    Pioneer Diversified High Income Trust | Annual Report | 4/30/09


higher rated debt securities. The Trust may invest in securities of issuers
that are in default or that are in bankruptcy.

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 gains and losses 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 preparation of its financial statements, which are consistent with
those 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. For Loan Interests for which no reliable price quotes are
     available, such investments are valued by Loan Pricing Corporation through
     the use of pricing matrices to determine valuations.

     Fixed-income securities are valued at prices supplied by independent
     pricing services, which consider such factors as Treasury spreads, yields,
     maturities and ratings. Valuations may be supplemented by values obtained
     from dealers and other sources, as required. Equity securities are valued
     at the last sale price on the principal exchange where they are traded.
     Securities or Loan Interests for which market prices and/or quotations are
     not readily available are valued using fair value methods pursuant to
     procedures adopted by the Board of Trustees ("board determined"). Trading
     in foreign securities is substantially completed each day at various times
     prior to the close of the NYSE. The values of such securities used in
     computing the net asset value of the Trust's shares are determined as of
     such times. The Trust may also use fair value methods to value a security,
     including a non-U.S. security, when the closing market price on the primary
     exchange where the security is traded no longer accurately reflects the
     value of the security as of the close of the NYSE. As of April 30, 2009,
     there were no securities valuations that were board determined. Temporary
     cash investments are valued at amortized cost which approximates market
     value.

     Dividend income is recorded on the ex-dividend date, except that certain
     dividends from foreign securities where the ex-dividend date may have
     passed are recorded as soon as the Trust becomes aware of the ex-dividend
     data in the exercise of reasonable diligence. Discounts and premiums on

           Pioneer Diversified High Income Trust | Annual Report | 4/30/09    39


     debt securities are accreted or amortized, respectively, daily, on an
     effective yield to maturity basis and are included in interest income.
     Premiums and discounts related to certain mortgage-backed securities are
     amortized or accreted in proportion to the monthly paydowns. Interest
     income, including income on interest bearing cash accounts, is recorded on
     an accrual basis. Dividend and interest income are reported net of
     unrecoverable foreign taxes withheld at the applicable country rates.

     Gains and losses on sales of investments are calculated on the identified
     cost method for both financial reporting and federal income tax purposes.

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
     the appropriate 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 as a hedge or cross-hedge against either specific investment
     transactions (settlement hedges) or portfolio positions (portfolio hedges).
     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 4).

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

40    Pioneer Diversified High Income Trust | Annual Report | 4/30/09


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

     At April 30, 2009, the Trust reclassified $231,317 to decrease
     distributions in excess of net investment income and $231,317 to increase
     accumulated net realized loss on investments. The reclassification has no
     impact on the net asset value of the Trust and presents the Trust's capital
     accounts on a tax basis.

     The Trust has elected to defer approximately $14,228,771 in capital losses
     realized and $585,166 in currency losses realized between November 1, 2008
     and April 30, 2009 to its fiscal year ending April 30, 2010.

     At April 30, 2009, the Trust had a net capital loss carryforward of
     $644,894 which is comprised of $231,744 which will expire in 2016 and
     $413,150 which will expire in 2017, if not utilized.

     The tax character of current year distributions paid to shareowners during
     the year ended April 30, 2009 and the period ended April 30, 2008 were as
     follows:



                                         2009            2008
                                             
     Distributions paid from:
     Ordinary income              $20,135,595      $14,530,763
     Tax return of capital            371,077               --
     ---------------------------------------------------------
       Total                      $20,506,672      $14,530,763
     =========================================================


     The following shows the components of distributable earnings on a federal
     income tax basis at April 30, 2009.



                                   
     Distributable earnings:
     Capital loss carryforward        $    (644,894)
     Post-October loss deferred         (14,813,937)
     Dividends payable                   (1,551,526)
     Unrealized depreciation            (63,239,755)
     -----------------------------------------------
       Total                          $ (80,250,112)
     ===============================================


     The difference between book-basis and tax-basis unrealized depreciation is
     primarily attributable to the tax deferral of losses on wash sales, the
     realization for tax purposes of unrealized losses on certain foreign
     currency contracts, the book/tax differences in the accrual of income on
     securities in

           Pioneer Diversified High Income Trust | Annual Report | 4/30/09    41


     default, the difference between book and tax amortization methods for
     premiums and discounts on fixed income securities and other book/tax
     temporary differences.

E.   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 at least equal to or in excess of the value of the
     repurchase agreement. The collateral for all repurchase agreements is held
     in safekeeping in the customer-only account of the Trust's custodian, or
     subcustodians. PIM is responsible for determining that the value of the
     collateral remains at least equal to the repurchase price.

F.   Securities Lending

     The Trust lends securities in its portfolio to certain broker-dealers or
     other institutional investors. When entering into a securities loan
     transaction, the Trust typically receives cash collateral from the borrower
     equal to at least the value of the securities loaned, which is invested in
     temporary cash investments. Credit Suisse, New York Branch, as the Trust's
     securities lending agent, manages the Trust's securities lending
     collateral. The income earned on the investment of collateral is shared
     with the borrower and the lending agent in payment of any rebate due to the
     borrower with respect to the securities loan, and in compensation for the
     lending agent's services to the Trust. The Trust also continues to receive
     interest or payments in lieu of dividends on the securities loaned. Gain or
     loss on the value of the loaned securities that may occur during the term
     of the loan will be for the account of the Trust. The amount of the
     collateral is required to be adjusted daily to reflect any price
     fluctuation in the value of the loaned securities. The Trust has the right,
     under the lending agreement, to terminate the loan and recover the
     securities from the borrower with prior notice. The Trust will be required
     to return the cash collateral to the borrower and could suffer a loss if
     the value of the collateral, as invested, has declined.

G.   Automatic Dividend Reinvestment Plan

     All common shareowners automatically participate in the Automatic Dividend
     Reinvestment Plan (the Plan), under which participants receive all
     dividends and capital gain distributions (collectively, dividends) in full
     and fractional common shares of the Trust in lieu of cash. Shareowners may
     elect not to participate in the Plan. Shareowners not participating in the
     Plan receive all dividends and capital gain distributions in cash.
     Participation in the Plan is completely voluntary and may be terminated or
     resumed at any time without penalty by notifying American Stock Transfer &
     Trust Company, the agent for shareowners in administering the Plan (the
     Plan

42    Pioneer Diversified High Income Trust | Annual Report | 4/30/09


     Agent), in writing prior to any dividend record date; otherwise such
     termination or resumption will be effective with respect to any
     subsequently declared dividend or other distribution.

     Whenever the Trust declares a dividend on common shares payable in cash,
     participants in the Plan will receive the equivalent in common shares
     acquired by the Plan Agent either (i) through receipt of additional
     unissued but authorized common shares from the Trust or (ii) by purchase of
     outstanding common shares on the American 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 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 the total
assets of the Trust, including any form of investment leverage, minus all
accrued expenses incurred in the normal course of operations, but not excluding
any liabilities or obligations attributable to investment leverage obtained
through (i) indebtedness of any type (including, without limitation, borrowing
through a credit facility or the issuance of debt securities), (ii) the issuance
of preferred stock or other similar preference securities, (iii) the
reinvestment of collateral received for securities loaned in accordance with the
Funds investment objectives and policies, and/or (iv) any other means. For the
year ended April 30, 2009, the net management fee was equivalent to 0.63% of the
Trust's average daily managed assets, which was equivalent to 0.88% of the
Trust's average daily net assets.

           Pioneer Diversified High Income Trust | Annual Report | 4/30/09    43


In addition, under PIM's management and administration agreements, certain
other services and costs are paid by PIM and reimbursed by the Trust. Included
in "Due to affiliates" reflected on the Statement of Assets and Liabilities is
$58,058 in management fees, administrative fees and certain other fees payable
to PIM at April 30, 2009.

PIM has retained Princeton Administrators, LLC (Princeton) to provide certain
administrative and accounting services to the Trust on its behalf. PIM pays
Princeton a monthly fee at an annual rate of 0.07% of the average daily value
of the Trust's managed assets up to $500 million and 0.03% of average daily
managed assets in excess of $500 million, subject to a minimum monthly fee of
$10,000. Princeton receives no compensation directly from the Trust.

Effective October 1, 2008, PIM has entered into a Research Services Agreement
with Montpelier Capital Advisors, Ltd. (Montpelier). Under the research
services agreement, Montpelier will provide research services to PIM with
regard to event-linked bonds. PIM pays Montpelier a flat fee of $325,000
annually. Prior to October 1, 2008, PIM had engaged Montpelier to act as the
Trust's investment sub-adviser with respect to the Trust's investments in
event-linked bonds. PIM paid Montpelier a monthly fee at an annual rate of
0.80% of the average daily value of the Trust's sub-advised assets; however,
the fee in no event was less than 0.15% of the Trust's average daily managed
assets. The fee was paid quarterly in arrears. Montpelier received no
compensation directly from the Trust.

Also, PIM has agreed for the first three years of the Trust's investment
operations to limit the Trust's total annual expenses, excluding offering costs
for common shares, interest expense, the cost of defending or prosecuting any
claim or litigation to which the Trust is a party (together with any amount in
judgment or settlement), indemnification expense or taxes incurred due to the
failure of the Trust to qualify as a regulated investment company under the
Code or any other non-recurring or non-operating expenses, to 0.90% of the
Trust's average daily managed assets in year one, 0.95% of the Trust's average
daily managed assets in year two and 1.00% of the Trust's average daily managed
assets in year three. This is a contractual limit and may not be terminated by
the adviser during the three year period ending on 2010. There can be no
assurance that it will be continued after that time. For the year ended April
30, 2009, the expense reduction under such arrangement was $418,949.

3.   Transfer Agents

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

44    Pioneer Diversified High Income Trust | Annual Report | 4/30/09


4. Forward Foreign Currency Contracts

The Trust may enter into contracts that obligate the Trust to deliver
currencies at specified future dates. At the maturity of a contract, the Trust
must make or take delivery of the foreign currency. Alternatively, prior to the
settlement date of a portfolio hedge, the Trust may close out such contracts by
entering into offsetting hedge contract.

Open portfolio hedges at April 30, 2009 were as follows:

Effective February 6, 2009, the Trust entered into a $55,000,000 Revolving
Credit Facility (the Credit Agreement) with the Bank of Nova Scotia.

At April 30, 2009, the Trust had a borrowing outstanding under the Credit
Agreement totaling $38,000,000. The interest rate charged at April 30, 2009 was
2.71%. The average daily balance was $54,191,781 at a weighted average interest
rate of 2.90%. With respect to the loan, interest expense of $1,595,281 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:

about Derivative Instruments and Hedging Activities (SFAS 161), was issued and
is effective for fiscal years beginning after November 15, 2008. SFAS 161
requires enhanced disclosures about an entity's derivative and hedging
activities. Management currently is evaluating the impact the adoption of SFAS
161 will have on the Trust's financial statement disclosures.

9.   Subsequent Event

Subsequent to April 30, 2009, the Board of Trustees of the Trust declared a
dividend from undistributed net investment income of $0.19 per common share
payable May 29, 2009, to shareowners of record on May 15, 2009.

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, 2009, and the related statements of operations and
cash flows for the year then ended, and the statements of changes in net assets
and the financial highlights for the periods indicated therein. 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, 2009, by correspondence with
the custodian, agent banks, 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
Pioneer Diversified High Income Trust at April 30, 2009, the results of its
operations and its cash flows for the year then ended, and the changes in its
net assets and financial highlights for the periods indicated therein, in
conformity with U.S. generally accepted accounting principles.

                                                            /s/Ernst & Young LLP

Approval of Investment Advisory Agreement (unaudited)

Pioneer Investment Management, Inc. (PIM) serves as the Trust's investment
adviser pursuant to an investment advisory agreement between PIM and the Trust.
The Trustees of the Trust, as required by law, determine annually whether to
continue the investment advisory agreement for the Trust.

The contract renewal process began in March 2008 as the Trustees of the Trust
agreed on, among other things, an overall approach and timeline for the
process. In July, the Trustees approved the format of the contract renewal
materials and submitted their formal request to PIM to furnish information
necessary to evaluate the terms of the investment advisory agreement. The
contract renewal materials were provided to the Trustees in August. After
reviewing and discussing the materials, the Trustees submitted a request for
additional information to PIM in September, and materials were provided in
response to this request later that month. Meetings of the Independent Trustees
of the Trust were held in September and October to review and discuss the
contract renewal materials.

At a meeting held on November 11, 2008, based on their evaluation of the
information provided by PIM, the Trustees of the Trust, including the
independent Trustees voting separately, unanimously approved the continuation
of the investment advisory agreement for another year. In considering the
continuation 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 continuation of the investment
advisory agreement.

Nature, Extent and Quality of Services
The Trustees considered the nature, extent and quality of the services that
were provided by PIM to the Trust, taking into account the investment objective
and strategy of the Trust and the information related to the Trust provided to
the Trustees at each regularly scheduled meeting. The Trustees reviewed the
terms of the investment advisory agreement. The Trustees also reviewed PIM's
investment approach for the Trust and its research process. The Trustees
considered the resources of PIM and the personnel of PIM who provide investment
management services to the Trust. They also considered PIM's compliance and
legal resources and personnel.

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

           Pioneer Diversified High Income Trust | Annual Report | 4/30/09    49


Based on these considerations, the Trustees concluded that the nature, extent
and quality of services that were 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
average 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 noted that
the Trust commenced operations on May 30, 2007. The Trustees considered that
the Trust's annualized total return was in the first quintile of its
Morningstar category for the one year period ended June 30, 2008. (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 also would be first
quintile.) The Trustees noted that the yield (gross of expenses) to the Trust's
common shareowners for the twelve months ended June 30, 2008 exceeded the yield
of the Trust's benchmark index for the same period. The Trustees concluded that
the investment performance of the Trust was satisfactory.

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 Trust Research
and Consulting, LLC (Strategic Insight), an independent third party.

The Trustees considered that the Trust's management fee for the twelve months
ended June 30, 2008 was in the fourth quintile relative to the management fees
paid by other funds in its Strategic Insight peer group for the comparable
period. The Trustees considered that the Trust's management fee was 0.037%
higher than the median management fee of the peer group. The Trustees also
considered that the Trust's expense ratio for the twelve months ended June 30,
2008 was in the first quintile relative to its Strategic Insight peer group for
the comparable period. The Trustees noted the challenge of selecting a
comparable peer group for expense comparison purposes. It was noted that PIM
did not currently manage any separate accounts with an investment objective and
strategies that were similar to those of the Trust.

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. The Trustees also concluded that the Trust's expense ratio was reasonable,
taking into account the quality of services provided by PIM, the investment
performance of the Trust and the contractual expense limitation agreed to by
PIM with respect to the Trust.

50    Pioneer Diversified High Income Trust | Annual Report | 4/30/09


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
recognized that PIM should be entitled to earn a reasonable level of profit for
the services provided to the Trust. 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 and its size is relatively stable at an asset level that was
anticipated when the management fee initially was set, the Trustees concluded
that economies of scale were not a relevant consideration.

Other Benefits
The Trustees also 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 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
continuation of the investment advisory agreement for the Trust.

 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.

--------------------------------------------------------------------------------
GENERAL AUDIT COMMITTEE APPROVAL POLICY:
o For all projects, the officers of the Funds and the Fund's auditors will each
  make an assessment to determine that any proposed projects will not impair
  independence.

o Potential services will be classified into the four non-restricted service
  categories and the "Approval of Audit, Audit-Related, Tax and Other
  Services" Policy 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.

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, 2009 and 2008,
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 2009 and
$7,820 in 2008.

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

Item 5. Audit Committee of Listed Registrants

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

		    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. The funds investment subadviser also
has adopted certain compliance procedures which are designed to address these
types of conflicts. However, there is no guarantee that such procedures will
detect each situation in which a conflict might arise. See "Compensation of
Portfolio Managers" below.

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

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

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

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

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

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

     o    Quantitative  Investment  Performance.   The  quantitative  investment
          performance  calculation is based on pre-tax investment performance of
          all of the accounts  managed by the portfolio  manager (which includes
          the fund and any other accounts managed by the portfolio manager) over
          a  one-year   period  (20%   weighting)  and  four-year   period  (80%
          weighting),  measured for periods ending on December 31. The accounts,
          which  include the fund,  are ranked  against a group of mutual  funds
          with similar  investment  objectives and investment  focus (60%) and a
          broad-based  securities  market index measuring the performance of the
          same type of securities in which the accounts invest (40%),  which, in
          the case of the fund,  is the  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 may participate in other programs designed to reward
and retain key contributors. Senior executives or other key employees may be
granted performance units based on the stock price performance of UniCredit and
the financial performance of Pioneer Global Asset Management S.p.A., which are
affiliates of Pioneer. Portfolio managers also may participate in a deferred
compensation program, whereby deferred amounts are invested in one or more
Pioneer funds.

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

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

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


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

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


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


ITEM 11. CONTROLS AND PROCEDURES.

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

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


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

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

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

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


ITEM 12. EXHIBITS.

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

(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.
