Dear Shareowner,
--------------------------------------------------------------------------------
Welcome to Pioneer. We thank you for your investment in Pioneer Diversified
High Income Trust, and are pleased to provide you with the Trust's first
shareowner report since its inception on May 30, 2007.

Staying diversified and keeping your portfolio invested in the markets are two
general investment principles that have served investors well over time. They
were particularly useful guides in recent months, when an otherwise healthy
long-term bull market was buffeted by problems in the mortgage and banking
industries.

Since mid-year, issues tied to poor underwriting practices in the subprime
sector of the mortgage industry and to problems with risk management by banks
and hedge funds have resulted in increased market volatility and rising concern
about risks to U.S. economic growth.

U.S. economic growth has slowed over the past two years, though due as much to
the natural maturation of the cyclical expansion, as U.S. factories approached
full utilization and the labor market approached full employment, as to rising
commodity prices or short-term interest rates. The slowdown was, therefore, not
entirely unwelcome, as it reduced the threat of higher inflation. More
recently, however, there has been increasing concern that falling home prices,
and/or disruptions in financial markets pose a larger threat to continuing
economic growth, and we have seen two cuts in short-term interest rates from
the Federal Reserve despite strong economic growth in the second and third
quarters of this year. A weaker U.S. dollar has put upward pressure on some
prices, but it has also significantly benefited exporters and companies
competing in the global marketplace, stimulating U.S. economic growth.

Economic growth in the rest of the world remains relatively positive. In
Europe, solid GDP growth has driven unemployment lower and supported growing
consumption, although concerns about the impact of the strong Euro are a
persistent source of worry. Japanese economic growth continues, albeit at a
muted rate, and the country's deflationary problems are gradually receding.
Economic growth in emerging market countries remains faster than in the
developed world, led by China, which continues its rise as a world economic
power.

The U.S. Federal Reserve and the world's other central banks continue to pursue
policies aimed at producing low and stable inflation, believed to be the best
backdrop for steady economic growth and low average unemployment over the long
term. Keeping inflation low is also an important support for stock and bond
valuations, and so central bank policies have also been "investor friendly." We
view the Fed's recent rate cuts as temporarily "buying insurance" against a
credit crunch, which

Letter

would threaten economic growth, rather than as an abandonment of its commitment
to keeping inflation low.

Sudden swings in the markets are always to be expected. Just as staying
diversified and invested are important investment principles, it is also
important to pay attention to asset allocation. As always, we encourage you to
work closely with your financial advisor to find the mix of stocks, bonds and
money market assets that is best aligned to your particular risk tolerance and
investment objective.

Pioneer Diversified High Income Trust
--------------------------------------------------------------------------------
PORTFOLIO MANAGEMENT DISCUSSION 10/31/07
--------------------------------------------------------------------------------

Pioneer Diversified High Income Trust began operations on May 30, 2007, as a
closed-end fund with the primary objective of pursuing a high level of current
income, with the potential for capital appreciation as a secondary objective.
The Trust pursues its objectives by investing in high-yielding domestic and
foreign bonds, floating rate bank loans and event-linked bonds. The Trust
encountered a challenging investment environment during the first five months
of operations. Declining home values and a looming crisis in the subprime
mortgage market in the United States led to increasing volatility for
income-oriented securities, including high-yield bonds and bank loans. In the
following discussion, Andrew D. Feltus and Jonathan Sharkey provide an update
on the Trust and its investment strategies for the first five months of its
operations. Mr. Feltus and Mr. Sharkey, members of Pioneer's Fixed Income
Group, are responsible for the Trust's day-to-day management.


Q:  How did the Trust perform in the first five months of its operations?


A:  Pioneer Diversified High Income Trust had a total return of 1.07%, at net
    asset value, from its inception on May 30, 2007, through October 31, 2007.
    During the same period, the Trust's benchmark returned 0.34%. The
    benchmark is based on a 50% weighting of the Merrill Lynch Global High
    Yield and Emerging Markets Index and a 50% weighting of the CSFB Leveraged
    Loan Index. At market price, the Trust's total return for the period was
    -13.39%. During the period, the Trust provided a generous yield. The SEC
    yield at the end of the five-month period was 9.68%.

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

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

Q:  What were your principal strategies the in the first five months of the
    Trust's investment operations?


A:  The Trust is designed to maintain a balanced high-yielding strategy, seeking
    both high income and the potential for capital appreciation. To accomplish
    that, we draw upon the Pioneer's Fixed Income Group's expertise in credit
    research. In constructing a portfolio, we allocated 37.5% of Trust assets
    to global high yield securities, 37.5% to floating rate bank loans, and
    25% to event-linked bonds. The global high-yield allocation has been
    composed primarily of domestic, high-yield corporate bonds, although we
    also have exposure to emerging market debt and high-yield corporate bonds
    from developed nations. Our investments in bank loans were in
    floating-rate securities, often judged to be of generally higher quality
    than high-yielding bonds, with solid covenant protection. Event-linked
    bonds are mostly securities issued as re-insurance bonds against the
    possibility of high occurrences of natural catastrophes, such as
    hurricanes or earthquakes. In managing the event-linked bond allocation,
    we draw upon the expertise of Montpelier Capital Advisors, Ltd., as
    sub-advisor to the Trust. Montpelier has significant expertise in
    evaluating catastrophic and insurance-linked risk.


    The average credit quality of the Trust's investments on October 31, 2007
    was B.


Q:  How would you describe the investment environment from the Trust's inception
    on May 30, 2007, through the period ended October 31, 2007?


A:  Fixed-income and bank loan markets experienced significant volatility during
    the period. The bond market began to feel the effects of monetary
    tightening policies by the U.S. Federal Reserve Board ("Fed") and other
    major central banks. Early signs of a deceleration of growth, particularly
    in the United States, began to appear, while the most speculative part of
    the domestic economy in recent years - the housing industry - started to
    slump. Falling home values created problems in the subprime mortgage
    market, which began to affect the balance sheets of banks and other home
    lenders as well as investors in some mortgage-related securities. As major
    banks began disclosing information about their exposure to subprime
    mortgages, anxieties spread through the financial


                                                                               5


Pioneer Diversified High Income Trust

PORTFOLIO MANAGEMENT DISCUSSION 10/31/07                             (continued)
--------------------------------------------------------------------------------

    markets. In a general flight to quality, investors increasingly sought out
    the highest-quality, lowest-risk securities, moving away from high-yield
    corporate bonds as the market saw little reward for taking on the added
    credit risks of lower-rated corporate debt. Despite this trend, the
    underlying economic fundamentals of high-yield issuers remained strong.
    With corporations posting strong profits and solid balance sheets, the
    default rate of domestic high-yield corporate bonds stood at just 1.1% at
    the end of the period - far below the long-term average rates. Outside the
    U.S., high-yield bonds in Europe and other major industrialized nations
    performed in line with the domestic market, although the appreciation of
    most foreign currencies against the dollar boosted the returns of
    U.S.-based investors in foreign markets. Emerging market debt outperformed
    other parts of the high-yield universe.


    The market for bank loans changed dramatically during the five-month
    period since the Trust's inception, as growing problems in the subprime
    mortgage industry created secondary effects on the supply and demand
    dynamics for collateralized bank loans. Over the full period, bank loans
    backed by the assets of borrowing companies delivered generally positive
    results, as the market for loans improved substantially in August,
    September and October after experiencing considerable volatility in June
    and July. The period saw a transition from a seller's market, which
    favored borrowing companies, to a buyer's market, which favored investors
    such as mutual funds. Default rates for bank loans remained near historic
    lows of 0.5%.


    Event-linked bonds generally performed well over the five-month period
    since the Trust's inception, as they tended to appreciate in value, as
    well as pay high yields, during a period of relatively light insurance
    losses from a relatively mild hurricane season.


Q:  How did the Trust's investments influence performance during the period from
    May 30, 2007 through October 31, 2007?


A:  The Trust's investments in higher-yielding securities helped provide a
    generous income stream during the period, consistent with the primary
    investment objective. On a total return basis, the Trust's investments in
    event-linked bonds provided the most significant positive support, as many
    of the bonds appreciated in value even as they continued to provide high
    yields.

Pioneer Diversified High Income Trust
--------------------------------------------------------------------------------

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

    The investments in high-yielding corporate bonds suffered more price loss
    during the five-month period since the Trust's inception and held back
    Trust performance, although those bonds did recover somewhat in the final
    three months of the period. The allocation to bank loans produced positive
    performance, despite suffering some price erosion during a market slump in
    July and August. However, they recovered strongly during the final three
    months of the period.


Q:  What is your investment outlook?


A:  We believe the fixed-income markets are likely to stay volatile, but we
    think the Trust is well positioned because of its diversified portfolio of
    higher-yielding investments. We think we are likely to see an economic
    deceleration in the United States, but not a recession. The prices of
    high-yield bonds - as reflected in their yield advantages over Treasuries
    - are now more attractive after the summer corrections, and corporate
    profits continue to look healthy. We believe the default rate for
    high-yield debt and bank loans is likely to rise, but principally because
    it has been extremely low relative to long-term averages. We anticipate
    that the Fed will react to developments in the economy and the markets,
    and further cuts in the Fed funds rate are possible.


    While we see the potential for some continued instability in the bank loan
    market because of supply/demand imbalance, we anticipate that conditions
    should begin to stabilize in the first quarter of 2008. We anticipate that
    new loans entering the market in 2008 are likely to have stronger
    covenants to protect investors and are likely to have higher credit
    spreads - or yield premiums - reflecting both the supply/demand imbalance
    as well as the potential for increased defaults. In the meantime,
    investors in bank loans are being well compensated with competitive income
    for their investments, and although we expect default rates on the loans
    to increase, they remain very low by historical measures.


    Overall, we believe the Trust is well positioned with a diversified
    portfolio of high-yielding investments with the potential to produce a
    generous income stream.


                                                                               7

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

    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 will generally 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 up to 50% of its total assets in illiquid securities.
    Illiquid securities may be difficult to dispose of at a fair price at the
    times when the Trust believes it is desirable to do so and their market
    price is generally more volatile than that of more liquid securities.
    Illiquid securities are also 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 may use leverage through the issuance of preferred shares with
    an aggregate liquidation preference of up to 33 1/3% of the Trust's total
    assets after such issuance. Leverage creates significant risks, including
    the risk that the Trust's income or capital appreciation will not be
    sufficient to cover the cost of leverage, which may adversely affect the
    return for the holders of common shares and may be viewed by visiting the
    Securities and Exchange Commission's web site at http://www.sec.gov.

    Risks of investing in the Trust are discussed in greater detail in the
    Trust's registration statement on Form N-2 relating to its common shares.

    Any information in this shareowner report regarding market or economic
    trends or the factors influencing the Trust's historical or future
    performance are statements of the opinion of Trust management as of the

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

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

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

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

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

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

The 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.

NOTES TO FINANCIAL STATEMENTS 10/31/07 (unaudited)
--------------------------------------------------------------------------------

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 UniCredito Italiano S.p.A.
(UniCredito Italiano), of 4,188 shares of beneficial interest at an aggregate
purchase price of $100,000. PIM has agreed to pay all the Trust's organizational
expenses and to pay the amount by which the aggregate offering costs (other than
the sales load) exceed $0.05 per share of the common share offering. The
investment objective of the Trust is to provide a high level of current income.
The Trust will, as a secondary objective, also seek preservation of capital to
the extent consistent with its primary goal of high current income.

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
"catastrophic" 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 and/or subadviser 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


34


Pioneer Diversified High Income Trust
--------------------------------------------------------------------------------

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

principal. These securities involve greater risk of loss, are subject to
greater price volatility, and are less liquid, especially during periods of
economic uncertainty or change, than higher rated debt securities. The Trust
may invest in securities of issuers that are in default or that are in
bankruptcy.

The Trust's 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 period. 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
    floating rate loans 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 the limited number of loans for which no reliable
    price quotes are available, such investments will be 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 loans for which quotations are not readily available are
    valued at their fair values as determined by, or under the direction of,
    the Board of Trustees. 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


                                                                              35


Pioneer Diversified High Income Trust
--------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 10/31/07 (unaudited) (continued)
--------------------------------------------------------------------------------

    also use the fair value of 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 exchange. As of October 31, 2007, the Trust held no fair
    valued securities. Temporary cash investments are valued at amortized
    cost.

    Dividend income is recorded on the ex-dividend date, except that certain
    dividends from foreign securities where the ex-dividend date may have
    passed are recorded as soon as the Trust becomes aware of the ex-dividend
    data in the exercise of reasonable diligence. Discount and premium on debt
    securities are accreted or amortized, respectively, daily, on an effective
    yield to maturity basis and are included in interest income. Interest
    income, including income on interest bearing cash accounts, is recorded on
    an accrual basis.

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


B.  Foreign Currency Translation

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

    Net realized gains and losses on foreign currency transactions 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 price of those securities but are included
    with the net realized and unrealized gain or loss on investments.


C.  Forward Foreign Currency Contracts

    The Trust enters 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


36


Pioneer Diversified High Income Trust
--------------------------------------------------------------------------------

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

    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 contract
    and from unanticipated movements in the value of foreign currencies
    relative to the U.S. dollar (see Note 3).


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.

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

    The tax character of current year distributions paid will be determined at
    the end of the current fiscal year.


E.  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 Agent"), in writing prior to any
    dividend record date;


                                                                              37


Pioneer Diversified High Income Trust
--------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 10/31/07 (unaudited) (continued)
--------------------------------------------------------------------------------

    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" is the average daily
value of the Trust's total assets minus the sum of the Trust's liabilities,
which liabilities exclude debt related to leverage, short-term debt and the
aggregate liquidation preference of any outstanding preferred shares. For the
period ended October 31, 2007, the net management fee was equivalent to 0.70%
of the Trust's average daily managed assets.


38


Pioneer Diversified High Income Trust
--------------------------------------------------------------------------------

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

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 affiliate" reflected on the Statement of Assets and Liabilities is
$128,020 in management fees, administrative costs and certain other services
payable to PIM at October 31, 2007.

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

PIM has engaged Montpelier Capital Advisors, Ltd. to act as the Trust's
investment sub-adviser ("Sub-adviser") with respect to the Trust's investments
in event-linked bonds. PIM pays the Sub-adviser a monthly fee at an annual rate
of 0.80% of the Trust's average daily Sub-advised assets; provided, however,
that such fee shall in no event be less than 0.15% of the Trust's average daily
managed assets. The fee is paid monthly in arrears. The Sub-adviser receives 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 1, 0.95% of the Trust's average
daily managed assets in year 2 and 1.00% of the Trust's average daily managed
assets in year 3. This is a contractual limit and may not be terminated by the
adviser for three years. There can be no assurance that it will be continued
after that time. For the period ended October 31, 2007, the expense reduction
under such arrangements was $114,059.


                                                                              39

3. 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 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 an offsetting hedge contract. At October 31, 2007, the Trust had
no outstanding portfolio hedges or forward currency settlement contracts.


4. Unfunded Loan Commitments

As of October 31, 2007, the Trust had unfunded loan commitments of
approximately $1,159,000 which extended at the option of the borrower, pursuant

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



Offering costs of $407,500 incurred in connection with the Trust's
offering of common shares have been charged to paid-in capital.


7. New Pronouncements

In September 2006, Statement of Financial Accounting Standards No. 157 Fair
Value Measurements ("SFAS 157") was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. At this time, management is currently evaluating the implications
of SFAS 157 and its impact on the Trust's financial statement disclosures, if
any, has not been determined.


8. Subsequent Event

Subsequent to October 31, 2007, the Board of Trustees of the Trust declared a
dividend from undistributed net investment income of $0.198 per common share
payable November 30, 2007, to common shareowners of record on November 15,
2007.


                                                                              41

 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.
