President's Letter

Dear Shareowner,

At mid-year, economic conditions and government policies around the world are
far from homogeneous, and we expect them to continue to diverge. In the United
States, an ongoing economic expansion has brought the unemployment rate down to
levels where wage growth is likely to accelerate. Economic growth and fiscal
austerity have dramatically reduced the Federal budget deficit, while very
accommodative Federal Reserve System policies have kept interest rates
exceptionally low. In Europe and Japan, cyclical economic recoveries/ expansions
appear to be gaining traction, buttressed by aggressive quantitative easing
policies of central banks as well as cheaper currencies. China's ongoing
transition from an infrastructure investment-driven to a consumer-driven economy
and the dramatic decline in the price of oil -- largely a result of U.S.
"fracking" -- have benefited some countries while burdening others. On balance,
though, the global economic outlook has continued to improve, although economic
and geopolitical "storm clouds" remain.

Today's market environment presents numerous opportunities as well as challenges
for investors. While we believe that the capital markets may already have priced
in some recent trends, such as the U.S. dollar's appreciation against a basket
of global currencies, it is worth noting that investment risks and opportunities
are not always aligned with the economic outlook.

Since 1928, Pioneer's investment professionals have focused on identifying and
capitalizing on the investment opportunities that present themselves in a
variety of ever-changing economic and market conditions, including those we face
today, while seeking to limit the risk of the permanent impairment of our
clients' capital. Our ongoing goal is to deliver competitive returns consistent
with our strategies' stated style and objectives and consistent with our
shareholders' expectations over a range of market conditions. We believe our
shareowners benefit from the experience and tenure of our investment teams, the
insights generated from extensive research resources, and our commitment to
prudent risk management.

We encourage you to work with your financial advisor to develop an overall
investment plan that addresses both your short- and long-term goals, and to
implement such a plan in a disciplined manner, as we do when managing the assets
our clients have entrusted to us.

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

Sincerely,

/s/ Lisa M. Jones

Portfolio Management Discussion | 4/30/15

The environment for global high-yield securities deteriorated throughout the
12-month period ended April 30, 2015, as investor confidence weakened due to
concerns about global economic growth, volatility in world commodity prices and
heightened geopolitical risks. In the following interview, Andrew Feltus,
Charles Melchreit and Jonathan Sharkey discuss the factors that affected the
performance of Pioneer Diversified High Income Trust during the 12-month period.
Mr. Feltus, Director of High Yield and Bank Loans, a senior vice president and a
portfolio manager at Pioneer, Mr. Melchreit, Director of Investment-Grade
Management, a senior vice president and a portfolio manager at Pioneer, and Mr.
Sharkey, a senior vice president and a portfolio manager at Pioneer, are
responsible for the day-to-day management of the Trust.

Q How did the Trust perform during the 12-month period ended April 30, 2015?

A Pioneer Diversified High Income Trust returned 1.21% at net asset value and
  -7.90% at market price for the 12-month period ended April 30, 2015. During
  the same 12-month period, the Trust's custom benchmark returned 0.91% at net
  asset value. The custom benchmark is based on equal weights of the Bank of
  America Merrill Lynch (BofA ML) Global High Yield and Emerging Markets Plus
  (GHY and EMP) Index, which returned -1.70% at net asset value during the
  12-month period, and the Credit Suisse (CS) Leveraged Loan Index, which
  returned 3.52%. Unlike the Trust, the custom benchmark does not use leverage.
  While the use of leverage increases investment opportunity, it also
  increases investment risk. During the same 12-month period, the average
  return (at market price) of the 32 closed end funds in Lipper's High Current
  Yield Closed End Funds Category (which may or may not be leveraged) was
  -2.24%, and the average return (at market price) of the 22 closed end funds
  in Lipper's Loan Participation Closed End Funds Category (which may or may
  not be leveraged) was 2.90%.

  The shares of the Trust were selling at a 5.6% discount to net asset value at
  the end of the period on April 30, 2015.

  On April 30, 2015, the 30-day SEC yield on the Trust's shares was 6.38%*.

Q How would you describe the investment environment for high-yield securities
  during the 12-month period ended April 30, 2015?

A At the beginning of the 12-month period, higher-yielding and more credit-
  sensitive securities tended to be in favor with investors, but their
  performance gradually weakened due to several factors. One of the primary
  concerns of market participants revolved around the potential risks of
  further policy

  hypothetical annualized earning power (investment income only) of the Trust's
  portfolio securities during the period indicated.

  tightening by the U.S. Federal Reserve System (the Fed) in the form of an
  interest-rate hike. As the period progressed, other developments, many in
  foreign markets, also had a negative impact on high-yield markets. Examples
  included continuing weakness in Europe's economy and slowing economic growth
  in China. Moreover, many emerging economies suffered both from the feared
  effects of potentially higher interest rates in the United States and the
  continuing slide in world commodity prices, notably the dramatic plunge of
  crude oil prices over the final months of 2014.

  While lower energy prices may have been welcomed by many consumers and
  oil-consuming industries, they proved disruptive to the U.S. high-yield bond
  market, as 16% of the market is represented by energy issuers. Geopolitical
  risks to the global economy also increased during the 12-month period, as
  ongoing tensions between Russia and the Ukraine resulted in steps taken by
  the U.S. and many European nations to impose economic sanctions on Russia.
  The sanctions, however, may have further weakened some western European
  economies. Meanwhile, the rise of ISIS in the Middle East sparked new violence
  across the region, violence which persisted throughout the period and
  threatened to increase instability in other parts of the world.

  Despite the many issues which developed, one relative bright spot for most of
  the period was the United States economy. Following a weak first quarter of
  2014, the U.S. economy, as measured by gross domestic product (GDP), grew at
  a healthy - though hardly robust - average rate of 2.39% during the remainder
  of 2014. Economic indices measuring employment, consumer spending,
  manufacturing output and housing industry trends all showed improvement over
  the final three quarters of 2014. The new year, however, brought renewed
  concerns about the domestic economy, as GDP fell to just a 0.2% pace in the
  first quarter of 2015 (subsequently revised even lower). Although the labor
  market continued to improve, manufacturing data was disappointing, feeding
  the market's fears that the economic revival was sputtering. Intermediate-
  and longer-term U.S.  Treasuries, which are less sensitive to the economic
  cycle, continued to increase in price as interest rates fell over the first
  quarter of 2015, but credit-sensitive investments, including prices of
  high-yield corporate bonds, generally underperformed Treasuries.

  Outside the U.S., in the latter part of the 12-month period, the European
  Central Bank (ECB) implemented a policy of quantitative easing (which
  involves bond purchases) to help support economies in the euro zone. In turn,
  the relative performance of European high-yield bonds began to improve as
  investors, especially in Europe, sought better yields in an environment that
  featured declining rates on government bonds and investment-grade corporates.
  Encouragingly, there were signs of some gains in the European economy during
  the first quarter of 2015. Meanwhile, the

               Pioneer Diversified High Income Trust | Annual Report | 4/30/15 5


  emerging markets started to improve as well, although the performance of
  emerging markets debt continued to lag that of the U.S. high-yield market.
  Economic growth in China seemed to be stabilizing early in 2015 after
  decelerating during much of 2014.

  Despite some weakening in the final weeks of the period, the U.S. dollar
  strengthened in world currency markets for almost the entire 12 months.
  Falling oil and commodity prices and declining interest rates in Europe gave
  further support to the U.S. currency.

Q Could you review your principal investment strategies during the 12-month
  period ended April 30, 2015, and how those strategies affected the Trust's
  performance relative to the customized benchmark?

A We had overweighted the Trust's portfolio to U.S. high-yield corporates
  during the period. The domestic high-yield corporate market, as we noted
  earlier, has a heavy energy-industry component, and so the Trust's over-
  weight position to high-yield corporates was a major drag on
  benchmark-relative performance as energy companies, by and large, struggled
  over the final half of the period due to plummeting oil prices. In
  particular, the high-yield securities issued by energy exploration and
  production (E&P) companies and oil field services companies tended to
  underperform, though they recovered to a certain degree when oil prices
  started rising again in the latter weeks of the 12-month period.

  Another allocation that underperformed and held back the Trust's relative
  performance during the period was emerging markets debt. The asset class, as
  discussed previously, was affected by weak commodity prices, slowing growth
  in China and concerns about potential interest-rate increases in the United
  States.

  On the bright side, we invested in event-linked (catastrophe) bonds issued by
  property-and-casualty insurers and in floating-rate bank loans during the
  period, and those positions tended to boost the Trust's performance. Both
  catastrophe bonds and bank loans feature floating-rate coupons, which rise as
  interest rates increase. Catastrophe bonds held up well during a relatively
  mild 2014 hurricane season, while floating-rate bank loans outperformed
  high-yield corporates.

  With regard to individual securities, some of the high-yield energy positions
  in the Trust's portfolio that were notable detractors from benchmark-relative
  performance included the bonds of E&P companies Energy XXI and Samson Oil &
  Gas, and Hercules Offshore, an oil field services company. High-yield bond
  positions that fared well during the period included the securities issued by
  Tragus, an Australian utility company, and some higher-quality energy firms,
  including Sanchez Energy, an E&P company that outpaced many of its peers in
  the industry. Finally, the convertible debt of Hologic, a manufacturer of
  medical equipment, also helped to support the Trust's relative results.

6 Pioneer Diversified High Income Trust | Annual Report | 4/30/15


  At the end of the period, on April 30, 2015, roughly 65% of the Trust's total
  investment portfolio was allocated to corporate bonds and notes, while nearly
  22% of the Trust's total investment portfolio was allocated to senior secured
  floating-rate bank loans. With regard to catastrophe bonds, we slightly
  reduced the Trust's allocation late in the fiscal year as we believed their
  prices had become somewhat high.

Q Can you comment on the Trust's allocation to insurance-linked securities (ILS)
  during the 12-month period ended April 30, 2015?

A ILS continued to be a core component of the Trust's investment strategy during
  the period, with 19.3% of the Trust's total investment portfolio allocated to
  this market as of April 30, 2015. The positioning in ILS is consistent with
  the Trust's long-term strategy, in which the allocation to the asset class has
  generally ranged from 15% to 25% of the Trust's total investment portfolio.
  Prudent diversification** across risks, or "perils" (that is, trigger events
  such as hurricanes), is a critical part of the investment process. The Trust's
  risks are distributed across many geographic regions and perils, encompassing
  hurricane risk spread across various coastal regions of the U.S., from Texas
  to Maine; earthquake risk throughout the United States and Canada; winter
  storm risk in Western Europe; and both typhoon and earthquake risk in Japan
  and Australia. In addition, the Trust invests in diversified risks including
  tornadoes, crop failures, pandemics, and aviation accidents, while taking
  small portfolio exposures to other regions, including South and Central
  America, New Zealand, and the Caribbean.

  The insurance-linked market has seen significant new capital flows in recent
  quarters, as investors have sought the compelling returns and low correlations
  of the asset class. Consequently, we have seen downward pressure on yields.
  Because of the less-compelling risk-adjusted yields available from
  publicly-traded catastrophe bonds, we have reduced the Trust's allocation to
  riskier ILS deals in favor of those carrying relatively remote risks, as those
  securities have enjoyed comparatively stable pricing. To offset the income
  reduction in the portfolio, we have increased the Trust's allocation to
  private placement ILS, particularly quota share agreements. With quota share
  agreements, the Trust takes a proportional share of a sponsoring insurer's
  risk and, in return, the Trust earns a share of the company's premium income.
  We believe such deals present many excellent opportunities to invest in
  diversified pools of insurance risk and, given that they represent a less
  liquid part of the market, quota share agreements have continued to offer
  investors attractive "expected" returns.

  * Diversification does not assure a profit nor protect against loss in a
    declining market.

Q How did the level of leverage in the Trust change over the 12-month period
  ended April 30, 2015?

A At the end of the 12-month period, on April 30, 2015, 29.5% of the Trust's
  total managed assets were financed by leverage (or borrowed funds), compared
  with 28.7% of the Trust's total managed assets financed by leverage at the
  start of the period on May 1, 2014. While the amount of borrowed funds
  employed by the Trust during the period did not increase or decrease, the
  percentage increase was due to a decrease in the values of securities in which
  the Trust had invested.

Q Did the Trust have any investments in derivative securities during the
  12-month period ended April 30, 2015?

A Yes. We used currency forward contracts in an effort to offset the potential
  volatility effects of the Trust's investments in non-dollar-denominated
  securities. The hedging strategy tended to help the Trust's performance as
  the U.S. dollar appreciated against most other currencies over most of the
  period.

Q What were the significant factors affecting the Trust's yield during the
  12-month period ended April 30, 2015?

A The Trust's yield did decline during the 12-month period, due to a few key
  factors. As interest rates fell during the period and as older securities in
  the Trust's portfolio were either retired or were called by issuers, we
  inevitably had to re-invest those assets in securities with lower coupons.
  Also, we reduced the Trust's exposure to higher-yielding, lower-rated
  corporate bonds during the period, and that also resulted in a decline in the
  Trust's current income. In addition, the Trust has drawn on accumulated net
  investment income in paying the Trust's dividend in recent periods, but these
  reserves have been depleted.

Q What is your investment outlook?

A We remain positive about investment opportunities in the credit-sensitive
  sectors. Despite the sluggish GDP number for the domestic economy for the
  first quarter of 2015, the markets continue to expect that economic growth in
  the U.S. will strengthen.

  We anticipate that currency volatility is likely to continue to dominate
  global bond markets. We believe the Fed will remain cautious as it considers
  tightening monetary policy, but some tightening in the form of an upward
  movement in interest rates could be seen before the end of 2015. One key
  factor supporting that belief is the strength of the U.S. labor market, which
  has been adding jobs steadily and moving closer to the point at which wages
  begin to rise.

8 Pioneer Diversified High Income Trust | Annual Report | 4/30/15


  Elsewhere, we are beginning to see signs of improving economic growth trends
  in Europe and we continue to see evidence that China's growth rate is
  gradually slowing - but stabilizing - to levels below recent trends. We also
  believe China's current leadership is focused on fostering greater stability
  in the financial markets. Going forward, we believe the expansion of the
  global economy will be less dependent on trends in China and more sensitive
  to trends in other major industrialized and developing economies.

  Global interest rates are likely to increase from their current very low
  levels, as we see little evidence of deflationary pressures.

  Given this outlook, we plan to keep the duration of the Trust's portfolio
  relatively short in an attempt to protect principal and to give us the
  flexibility to take advantage of investment opportunities as they develop.
  (Duration is a measure of the sensitivity of the price - the value of
  principal - of a fixed-income investment to a change in interest rates,
  expressed as a number of years.)

  We think the yield advantages of credit-sensitive securities are about as high
  as they can go, but we also think they are appropriate given low default rates
  and our relatively optimistic view of the growth potential of the domestic and
  global economies. During the past 12 months, we saw a great deal of investment
  capital flow into the catastrophe bond sector, which has provided healthy
  support to prices in the asset class. However, we have begun to see the trend
  stabilize and, as we noted earlier, we have reduced the Trust's exposure,
  somewhat, to catastrophe bonds due to concerns over valuations and because we
  saw more interesting opportunities elsewhere.

  Going forward, we anticipate maintaining a healthy exposure in the Trust's
  portfolio to high-yield and other credit-sensitive debt, while looking for
  potential opportunities in floating-rate instruments such as bank loans. The
  loan asset class saw price appreciation over the past 12 months due to heavy
  issuance of collateralized loan obligations (CLOs), which are institutional
  pools of assets that invest in bank loans. Because of their floating rate
  nature, we believe both catastrophe bonds and bank loans should benefit when
  interest rates start rising due to the Fed's anticipated policy tightening,
  which is likely to occur in 2015.

Please refer to the Schedule of Investments on pages 14-44 for a full listing of
Trust securities.

Investments in high-yield or lower-rated securities are subject to greater-than-
average risk. The Trust may invest in securities of issuers that are in default
or that are in bankruptcy.

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

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

The Trust may invest a significant amount of its total assets in illiquid
securities. Illiquid securities may be difficult to dispose of at a price
reflective of their value at the times when the Trust believes it is desirable
to do so and the market price of illiquid securities is generally more volatile
than that of more liquid securities. Illiquid securities also are more difficult
to value, and investment of the Trust's assets in illiquid securities may
restrict the Trust's ability to take advantage of market opportunities.

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

The Trust is required to maintain certain regulatory and other asset coverage
requirements in connection with its use of leverage. In order to maintain
required asset coverage levels, the Trust may be required to reduce the amount
of leverage employed by the Trust, alter the composition of its investment
portfolio or take other actions at what might be inopportune times in the
market. Such actions could reduce the net earnings or returns to shareowners
over time, which is likely to result in a decrease in the market value of the
Trust's shares.

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

These risks may increase share price volatility.

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

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

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

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

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

The performance table and graph do not reflect the deduction of fees and taxes
that a shareowner would pay on Trust distributions or the sale of Trust shares.
Had these fees and taxes been reflected, performance would have been lower.

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

Index returns are calculated monthly, assume reinvestment of dividends and,
unlike Trust returns, do not reflect any fees, expenses or sales charges. The
indices do not use leverage. It is not possible to invest directly in an index.

Notes to Financial Statements | 4/30/15

1. Organization and Significant Accounting Policies

Pioneer Diversified High Income Trust (the Trust) was organized as a Delaware
statutory trust on January 30, 2007. Prior to commencing operations on May 30,
2007, the Trust had no operations other than matters relating to its
organization and registration as a diversified, closed-end management investment
company under the Investment Company Act of 1940, as amended. The investment
objective of the Trust is to seek a high level of current income and the Trust
may, as a secondary objective, also seek capital appreciation to the extent that
it is consistent with its investment objective.

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

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

A. Security Valuation

   Security transactions are recorded as of trade date. Fixed-income securities
   are valued at prices supplied by independent pricing services, which
   consider such factors as market prices, market events, quotations from one
   or more brokers, Treasury spreads, yields, maturities and ratings.
   Valuations may be supplemented by dealers and other sources, as required.
   Senior floating rate loan interests (senior 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, an independent pricing service.  If
   price information is not available from Loan Pricing Corporation or if the
   price information is deemed to be unreliable, price information will be
   obtained from an alternative loan interest pricing service. If no reliable
   price quotes are available from either the primary or alternative pricing
   service broker quotes will be solicited. Event-linked bonds are valued at
   the bid price obtained from an independent third party pricing service.
   Other insurance-linked securities may be valued at the bid price obtained
   from an independent pricing service, or through a third party using a
   pricing matrix, insurance industry valuation models, or other fair value
   methods or techniques to provide an estimate value of the instrument.
   Equity securities that have traded on an exchange are

              Pioneer Diversified High Income Trust | Annual Report | 4/30/15 51


   valued at the last sale price on the principal exchange where they are
   traded. Equity securities that have not traded on the date of valuation or
   securities for which sale prices are not available, generally are valued
   using the mean between the last bid and asked prices. Shares of money market
   mutual funds are valued at such funds' net asset value.

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

   Securities and senior loans for which independent pricing services are
   unable to supply prices or for which market prices and/or quotations are not
   readily available or are considered to be unreliable are valued by a fair
   valuation team comprised of certain personnel of Pioneer Investment
   Management, Inc. (PIM), the Trust's investment adviser, pursuant to
   procedures adopted by the Trust's Board of Trustees. PIM's fair valuation
   team uses fair value methods approved by the Valuation Committee of the
   Board of Trustees. PIM's valuation team is responsible for monitoring
   developments that may impact fair valued securities and for discussing and
   assessing fair value on an ongoing basis, and at least quarterly, with the
   Valuation Committee of the Board of Trustees.

   Inputs used when applying fair value methods to value a security may
   include credit ratings, the financial condition of the company, current
   market conditions and comparable securities. The Trust may use fair value
   methods if it is determined that a significant event has occurred after the
   close of the exchange or market on which the security trades and prior to
   the determination of the Trust's net asset value. Examples of a significant
   event might include political or economic news, corporate restructurings,
   natural disasters, terrorist activity or trading halts. Thus, the valuation
   of the Trust's securities may differ significantly from exchange prices and
   such differences could be material.

   At April 30, 2015, seven securities were valued using fair value methods
   (in addition to securities valued using prices supplied by independent
   pricing services or broker-dealers) representing 3.4% of net assets. The
   value of these fair valued securities are $5,267,051.

B. Investment Income and Transactions

   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 date in
   the exercise of reasonable diligence.

52 Pioneer Diversified High Income Trust | Annual Report | 4/30/15


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

   Discounts and premiums on purchase prices of debt securities are accreted or
   amortized, respectively, daily, into interest income on an effective yield
   to maturity basis with a corresponding increase or decrease in the cost
   basis of the security.  Premiums and discounts related to certain
   mortgage-backed securities are amortized or accreted in proportion to the
   monthly paydowns.

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

C. Foreign Currency Translation

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

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

D. Forward Foreign Currency Contracts

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

E. Federal Income Taxes

   It is the Trust's policy to comply with the requirements of the Internal
   Revenue Code applicable to regulated investment companies and to distribute
   all of its taxable income and net realized capital gains, if any, to its
   shareowners. Therefore, no federal income tax provision is required. As of
   April 30, 2015,

              Pioneer Diversified High Income Trust | Annual Report | 4/30/15 53


   the Trust did not accrue any interest or penalties with respect to uncertain
   tax positions, which if applicable, would be recorded as an income tax
   expense in the Statement of Operations. Tax returns filed within the prior
   three years remain subject to examination by federal and state tax
   authorities.

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

   At April 30, 2015, the Trust reclassified $1,268,193 to decrease
   distributions in excess of net investment income and $1,268,193 to increase
   accumulated net realized loss on investments to reflect permanent book/tax
   differences.  These adjustments have no impact on the net assets or results
   of operations.

   At April 30, 2015, the Trust was permitted to carryforward $806,616 of
   short-term capital losses and $8,599,595 of long-term capital losses without
   limitation.  Additionally, at April 30, 2015, the Trust had a net capital
   loss carryforward of $23,843,173 of which the following amounts will expire
   between 2016 and 2019 if not utilized: $231,744 in 2016, $413,150 in 2017,
   $21,948,862 in 2018, and $1,249,417 in 2019. Since unlimited losses are
   required to be used first, loss carryforwards that are subject to expiration
   may be more likely to expire unused.

   The Trust has elected to defer $633,267 of short-term capital losses and
   $5,939,394 of long-term capital losses recognized between November 1, 2014
   and April 30, 2015 to its fiscal year ending April 30, 2016.

   The tax character of distributions paid to shareowners during the years
   ended April 30, 2015 and April 30, 2014 were as follows:

   Late year loss deferrals                                           (6,572,661)
   Other book/tax temporary differences                               (1,811,057)
   Unrealized depreciation                                            (1,053,521)
   -----------------------------------------------------------------------------
        Total                                                       $(41,367,842)
   =============================================================================


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

F. Risks

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

   The Trust invests in below investment grade (high yield) debt securities,
   floating rate loans and event-linked bonds sometimes referred to as
   "catastrophe" bonds or "insurance-linked" bonds. The Trust may invest in
   securities and other obligations of any credit quality, including those that
   are rated below investment grade, or are unrated but are determined by the
   investment adviser to be of equivalent credit quality. Below investment
   grade securities are commonly referred to as "junk bonds" and are considered
   speculative with respect to the issuer's capacity to pay interest and repay
   principal. Below investment grade securities, including floating rate loans,
   involve greater risk of loss, are subject to greater price volatility, and
   are less liquid and more difficult to value, 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 value of collateral, if any, securing a floating rate loan
   can decline or may be insufficient to meet the issuer's obligations or may
   be difficult to liquidate. No active trading market may exist for many
   floating rate loans, and many loans are subject to restrictions on resale.
   Any secondary market may be subject to

              Pioneer Diversified High Income Trust | Annual Report | 4/30/15 55


   irregular trading activity and extended settlement periods. Additionally,
   the Trust may invest in "event-linked" bonds, which sometimes are referred
   to as "insurance-linked" or "catastrophe" bonds. The return of principal and
   the payment of interest on event-linked instruments are contingent on the
   nonoccurrence of pre-defined "trigger" events, such as hurricane or an
   earthquake of a specific magnitude. In addition to the specific trigger
   events, event-linked bonds may expose the Trust to other risks, including
   but not limited to issuer (credit) default, adverse regulatory or
   jurisdictional interpretations and adverse tax consequences. The Trust's
   investments in certain foreign markets or countries with limited developing
   markets may subject the Trust to a greater degree of risk than would
   investments in a developed market. These risks include disruptive political
   or economic conditions and the possible imposition of adverse governmental
   laws or currency exchange restrictions.

G. Repurchase Agreements

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

H. Automatic Dividend Reinvestment Plan

   All common shareowners whose shares are registered in their own names
   automatically participate in the Automatic Dividend Reinvestment Plan (the
   Plan), under which participants receive all dividends and capital gain
   distributions (collectively, dividends) in full and fractional common shares
   of the Trust in lieu of cash. Shareowners may elect not to participate in
   the Plan. Shareowners not participating in the Plan receive all dividends
   and capital gain distributions in cash. Participation in the Plan is
   completely voluntary and may be terminated or resumed at any time without
   penalty by notifying American Stock Transfer & Trust Company, the agent for
   shareowners in administering the Plan (the Plan Agent), in writing prior to
   any dividend record date; otherwise such termination or resumption will be
   effective with respect to any subsequently declared dividend or other
   distribution.

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

56 Pioneer Diversified High Income Trust | Annual Report | 4/30/15


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

I. Option Writing

   The Trust may write put and covered call options to seek to increase total
   return. When an option is written, the Trust receives a premium and becomes
   obligated to purchase or sell the underlying security at a fixed price, upon
   the exercise of the option. When the Trust writes an option, an amount equal
   to the premium received by the Trust is recorded as a liability and is
   subsequently adjusted to the current value of the option written. Premiums
   received from writing options that expire unexercised are treated by the
   Trust on the expiration date as realized gains from investments. The
   difference between the premium and the amount paid on effecting a closing
   purchase transaction, including brokerage commissions, is also treated as a
   realized gain, or, if the premium is less than the amount paid for the
   closing purchase transaction, as a realized loss. If a call option is
   exercised, the premium is added to the proceeds from the sale of the
   underlying security in determining whether the Trust has realized a gain or
   loss. The Trust as a writer of an option bears the market risk of an
   unfavorable change in the price of the security underlying the written
   option.

              Pioneer Diversified High Income Trust | Annual Report | 4/30/15 57


   The average value of option contracts open for the year ended April 30, 2015
   was $659. There were no written call and put option contracts outstanding at
   year end.

   Transactions in written call options for the year ended April 30, 2015 are

J. Purchased Options

   The Trust may purchase put and call options to seek increase total return.
   Purchased call and put options entitle the Trust to buy and sell a specified
   number of shares or units of a particular security, currency or index at a
   specified price at a specific date or within a specific period of time. Upon
   the purchase of a call or put option, the premium paid by the Trust is
   included in the Statement of Assets and Liabilities as an investment. All
   premiums are marked-to-market daily, and any unrealized gains or losses are
   recorded in the Trust's financial statements. As the purchaser of an index
   option, the Trust has the right to receive a cash payment equal to any
   depreciation in the value of the index below the strike price of the option
   (in the case of a put) or equal to any appreciation in the value of the
   index over the strike price of the option (in the case of a call) as of the
   valuation date of the option. Premiums paid for purchased calls and put
   options which have expired are treated as realized losses on investments in
   the Statement of Operations. Upon the exercise or closing of a purchased put
   option, the premium is offset against the proceeds on the sale of the
   underlying security or financial instrument in order to determine the
   realized gain or loss on investments. Upon the exercise or closing of a
   purchased call option, the premium is added to the cost of the security or
   financial instrument. The risk associated with purchasing options is limited
   to the premium originally paid. The average value of purchased options
   during the year ended April 30, 2015 was $2,044. There were no purchased
   option contracts outstanding at year end.

2. Management Agreement

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

58 Pioneer Diversified High Income Trust | Annual Report | 4/30/15


total assets of the Trust, including any form of investment leverage, minus (b)
all accrued liabilities incurred in the normal course of operations, which shall
not include any liabilities or obligations attributable to investment leverage
obtained through (i) indebtedness of any type (including, without limitation,
borrowing through a credit facility or the issuance of debt securities), (ii)
the issuance of preferred stock or other similar preference securities, and/or
(iii) any other means. For the year ended April 30, 2015, the net management fee
was 0.85% of the Trust's average daily managed assets, which was equivalent to
1.20% of the Trust's average daily net assets.

In addition, under PIM's management and administration agreements, certain other
services and costs are paid by PIM and reimbursed by the Trust. At April 30,
2015, $221,793 was payable to PIM related to management costs, administrative
costs and certain other services is included in "Affiliated expenses payable"
and "Administration fees payable" on the Statement of Assets and Liabilities.

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.

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

4. Expense Offset Arrangement

The Trust has entered into an arrangement with its custodian whereby credits
realized as a result of uninvested cash balances are used to reduce a portion of
the Trust's custodian expenses. For the year ended April 30, 2015, the Trust
expenses were not reduced under such arrangement.

5. Forward Foreign Currency Contracts

At April 30, 2015, the Trust had entered into various forward foreign currency
contracts that obligate the Trust to deliver or take delivery of currencies at
specified future maturity dates. Alternatively, prior to the settlement date of
a forward foreign currency contract, the Trust may close out such contract by
entering into an offsetting contract. The average value of contracts open during
the year ended April 30, 2015 was $12,692,322.

9. Loan Agreement

The Trust is in a credit agreement with the Bank of Nova Scotia. There is a $75
million borrowing limit.

At April 30, 2015, the Trust had a borrowing outstanding under the margin
agreement totaling $64,000,000. The interest rate charged at April 30, 2015 was
1.06%. During the year ended April 30, 2015, the average daily balance was
$65,912,000 at an average interest rate of 1.03%. With respect to the credit
agreement, interest expense of $681,002 is included in the Statement of
Operations.

              Pioneer Diversified High Income Trust | Annual Report | 4/30/15 61


The Trust is required to maintain 300% asset coverage with respect to amounts
outstanding under the margin loan financing 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 borrowing outstanding.

10. Subsequent Event

A monthly dividend was declared on May 5, 2015 from undistributed and
accumulated net investment income of $0.1350 per common share, payable May 29,
2015, to common shareowners of record on May 19, 2015.

11. Change in Independent Registered Public Accounting Firm

The Board of Trustees of the Trust, with the approval and recommendation of the
Audit Committee, appointed Deloitte & Touche LLP to serve as the Trust's
independent registered public accounting firm.  Deloitte & Touche LLP replaces
Ernst & Young LLP, which resigned as the Trust's independent registered public
accounting firm effective upon completion of the audit of the Trust's financial
statements for the fiscal year ended April 30, 2014.

During the periods that Ernst & Young LLP served as the Trust's independent
registered public accounting firm, including the Trust's fiscal years ending
April 30, 2014 and April 30, 2013, Ernst & Young LLP's reports on the financial
statements of the Trust have not contained an adverse opinion or disclaimer of
opinion and have not been qualified or modified as to uncertainty, audit scope
or accounting principles. Further, there have been no disagreements with Ernst &
Young LLP on any matter of accounting principles or practices, financial
statement disclosure, or auditing scope or procedure, which, if not resolved to
the satisfaction of Ernst & Young LLP would have caused Ernst & Young LLP to
make reference to the subject matter of the disagreement in connection with its
report on the financial statements. In addition, there have been no reportable
events of the kind described in Item 304(a)(1)(v) of Regulation S-K under the
Securities Exchange Act of 1934.

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, including
the schedule of investments, of Pioneer Diversified High Income Trust (the
"Trust") as of April 30, 2015, and the related statements of operations, cash
flows, changes in net assets, and the financial highlights for the year then
ended. These financial statements and financial highlights are the
responsibility of the Trust's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audit. The statement of changes in net assets of the Fund for the year ended
April 30, 2014, and the financial highlights for the years ended April 30, 2014,
2013, 2012, and 2011 were audited by other auditors. Those auditors expressed an
unqualified opinion on those financial statements and financial highlights in
their report dated June 25, 2014.

We conducted our audit 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. The Fund is not required to have, nor were we
engaged to perform an audit of its internal control over financial reporting.
Our audit 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 Fund'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, assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. Our procedures included confirmation of securities owned as of
April 30, 2015, by correspondence with the custodian, brokers and agent banks;
where replies were not received from brokers and agent backs, we performed other
auditing procedures. We believe that our audit provides 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 as of April 30, 2015, the results of its
operations, cash flows, changes in its net assets and financial highlights for
the year then ended, in conformity with accounting principles generally accepted
in the United States of America.

ADDITIONAL INFORMATION (unaudited)

PIM, the Trust's investment adviser, is currently an indirect, wholly-owned
subsidiary of UniCredit. On April 23, 2015, UniCredit announced that it signed a
preliminary and exclusive agreement with Banco Santander and affiliates of
Warburg Pincus and General Atlantic (the "Private Equity Firms") with respect to
Pioneer Investments ("Pioneer") and Santander Asset Management ("SAM") (the
"Transaction").

Pursuant to the preliminary agreement, the Transaction will entail the
establishment of a holding company, with the name Pioneer Investments, to be
owned by UniCredit (50%) and the Private Equity Firms (50% between them). The
holding company will control Pioneer's U.S. operations, including the Adviser.
The holding company also will own 66.7% of Pioneer's and SAM's combined
operations outside the U.S., while Banco Santander will own directly the
remaining 33.3% stake. The completion of the Transaction is subject to the
signing of a definitive agreement, as well as certain regulatory and corporate
approvals, and other conditions.

Under the Investment Company Act of 1940, completion of the Transaction will
cause the Trust's investment advisory agreement with the Adviser to terminate.
In connection with the Transaction, the Trust's Board of Trustees will be asked
to approve a new investment advisory agreement for the Trust. If approved by the
Board, the Trust's new investment advisory agreement will be submitted to the
shareholders of the Trust for their approval.

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

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

 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.

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.

Non-Audit Services
Beginning with non-audit service contracts entered into
on or after May 6, 2003, the effective date of the new
SEC pre-approval rules, the Trust's audit committee is
required to pre-approve services to affiliates defined by
SEC rules to the extent that the services are determined
to have a direct impact on the operations or financial
reporting of the Trust. For the years ended April 30, 2015
and 2014, 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 accountants 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 registrants accountant
for services rendered to the registrant, and rendered to the registrants
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 were $9,876
payable to Deloitte & Touche LLP for the year ended
April 30, 2015 and $8,131 were paid to the former
auditor, Ernst & Young LLP for the year ended April 30,
2014.

(h) Disclose whether the registrants audit committee of the board of trustees
has considered whether the provision of non-audit services that were rendered to
the registrants 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 registrant's audit committee as specified in
Section 3(a)(58)(B) of the Exchange Act (15 U.S.C. 78c(a)(58)(B)),
so state.

N/A

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

1 of this Form.

Included in Item 1


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

A closed-end management investment company that is filing an annual report on
this Form N-CSR must, unless it invests exclusively in non-voting securities,
describe the policies and procedures that it uses to determine how to vote
proxies relating to portfolio securities, including the procedures that the
company uses when a vote presents a conflict between the interests of its
shareholders, on the one hand, and those of the company's investment adviser;
principal underwriter; or any affiliated person (as defined in Section 2(a)(3)
of the Investment Company Act of 1940 (15 U.S.C. 80a-2(a)(3)) and the rules
thereunder) of the company, its investment adviser, or its principal
underwriter, on the other. Include any policies and procedures of the company's
investment adviser, or any other third party, that the company uses, or that are
used on the company's behalf, to determine how to vote proxies relating to
portfolio securities.

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

                            VERSION DATED July, 2004

                                    Overview

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

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

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

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

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

                                       1


                             Proxy Voting Procedures

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

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

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

                                       2


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

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

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

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

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

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

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

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

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

                                       3


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

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

   Share-Blocking

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

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

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

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

       o   Retains a record of the vote cast;

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

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

                                       4


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

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

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

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

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

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

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

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

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

                                       5


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

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

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

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

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

   We will generally support these and similar management proposals:

       o    Corporate name change.

       o    A change of corporate headquarters.

       o    Stock exchange listing.

       o    Establishment of time and place of annual meeting.

       o    Adjournment or postponement of annual meeting.

       o    Acceptance/approval of financial statements.

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

       o    Approval of minutes and other formalities.

                                       6


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

       o    Amendments to authorized signatories.

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

       o    Acceptance of labor agreements.

       o    Appointment of internal auditors.

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

Auditors
     We normally vote for proposals to:

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

       o    Restore shareholder rights to ratify the auditors.

     We will normally oppose proposals that require companies to:

       o    Seek bids from other auditors.

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

       o    Indemnify auditors.

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

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

                                       7


     General Board Issues
     Pioneer will vote for:

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

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

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

       o    Election of an honorary director.

     We will vote against:

       o    Minimum stock ownership by directors.

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

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

       o    Requirements to provide two candidates for each board seat.

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

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

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

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

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

     We will also vote against:

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

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

                                       8


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

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

       o    Contested election of directors.

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

       o    Mandatory retirement policies.

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

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

     Pioneer will vote for:

       o    Cumulative voting.

       o    Increase ability for shareholders to call special meetings.

       o    Increase ability for shareholders to act by written consent.

       o    Restrictions on the ability to make greenmail payments.

       o    Submitting rights plans to shareholder vote.

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

       o    Opting out of the following state takeover statutes:

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

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

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

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

                                       9


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

     o Fair price provisions.

     o Authorization of shareholder rights plans.

     o Labor protection provisions.

     o Mandatory classified boards.

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

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

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

       o    Proposals that allow shareholders to nominate directors.

     We will vote against:

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

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

       o    Classes of shares with unequal voting rights.

       o    Supermajority vote requirements.

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

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

       o    Extension of advance notice requirements for shareholder proposals.

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

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

                                       10


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

     Pioneer will vote for:

       o    Changes in par value.

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

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

       o    Bond issuance.

       o    Increases in "ordinary" preferred stock.

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

       o    Cancellation of company treasury shares.

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

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

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

     o Number of shares currently available for issuance;

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

     o Proposed use of the additional shares; and

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

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

       o    Proposals to submit private placements to shareholder vote.

       o    Other financing plans.

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

                                      11


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

     Pioneer will vote for:

       o    401(k) benefit plans.

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

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

     o Amendments to performance plans to conform with OBRA;

     o Caps on annual grants or amendments of administrative features;

     o Adding performance goals; and

     o Cash or cash-and-stock bonus plans.

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

       o    Require that option repricings be submitted to shareholders.

       o    Require the expensing of stock-option awards.

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

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

                                       12


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

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

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

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

            A = Shares reserved for plan/amendment,

            B = Shares available under continuing plans,

            C = Shares granted but unexercised and

            D = Shares outstanding.

       o    The plan must not:

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

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

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

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

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

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

       o    All other employee stock purchase plans.

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

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

                                       13


     We will vote against:

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

       o    Elimination of stock option plans.

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

       o    Limits on executive and director pay.

       o    Stock in lieu of cash compensation for directors.

     Corporate Governance
     Pioneer will vote for:

       o    Confidential Voting.

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

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

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

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

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

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

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

     We will vote against:

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

       o    Limitations on stock ownership or voting rights.

       o    Reduction in share ownership disclosure guidelines.

                                       14


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

       o    Mergers and acquisitions.

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

       o    Debt restructurings.

       o    Conversion of securities.

       o    Issuance of shares to facilitate a merger.

       o    Private placements, warrants, convertible debentures.

       o    Proposals requiring management to inform shareholders of merger
            opportunities.

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

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

     Pioneer will vote for:

       o    Establishment of new classes or series of shares.

       o    Establishment of a master-feeder structure.

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

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

       o    Approval of new or amended advisory contracts.

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

       o    Authorization for, or increase in, preferred shares.

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

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

                                       15


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

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

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

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

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

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

                                       16

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


                                       0


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

  - The significant investment strategies for Pioneer Diversified High Income
    Trust (a closed-end fund) and certain other similarly managed accounts
    with investment objectives of a high level of current income, with a
    potential for capital appreciation as a secondary objective. The fund
    invests in a unique blend of higher yielding asset classes, including
    global high yield bonds, leveraged bank loans and event-linked bonds (cat
    bonds).

Under normal market conditions, the fund invests at least 80% of its managed
assets (net assets plus borrowings or other leverage for investment purposes)
in diversified portfolio of below investment grade (high yield) debt
securities, loans and preferred stocks. The fund allocates its investments
principally among three sectors of the fixed income securities markets: (i)
below investment grade debt securities and preferred stocks of U.S. and
non-U.S. issuers, including governmental and corporate issuers in emerging
markets ("global high yield debt securities"), (ii) floating rate loans and
(iii) "event-linked" bonds, which sometimes are referred to as
"insurance-linked" or "catastrophe" bonds.

PIM believes that this actively managed, diversified portfolio of asset classes
- global high yield debt securities, floating rate loans and event-linked bonds
- may provide investors with a range of potential benefits across various
market cycles and under various market conditions. These benefits include,
among others, the potential to provide investors with a relatively high level
of current income without undue risk as a result of the low correlation among
these asset classes, reduced volatility due to limited exposure to interest
rate and duration risk, as well as a favorable risk return profile.
Specifically, the floating rate feature of both floating rate loans and
event-linked bonds serves to reduce sensitivity to changes in prevailing
interest rates. In addition, the introduction of event-linked bonds to the
diversified portfolio enhances these benefits by reducing volatility, while
providing the potential for above average returns. Moreover, the fund's
investments in event-linked bonds offer investors access to a unique asset
class that otherwise may be unavailable to them.

The fund does not have a policy of maintaining a specific average credit
quality or a targeted maturity range for its portfolio. The fund may invest any
portion of its assets in securities and other instruments of non-U.S. issuers,
including emerging market issuers, and may engage in certain strategic
transactions.

PIM is responsible for managing the fund's overall investment program,
including allocating the fund's investments among the different asset classes
and managing the fund's investments in global high income debt securities and
floating rate loans. PIM considers both broad economic and issuer specific
factors in selecting a portfolio designed to achieve the fund's investment
objectives. PIM selects individual securities based upon the terms of the
securities (such as yields compared to U.S. Treasuries or comparable issues),
liquidity and rating, sector and issuer diversification. PIM also employs due
diligence and fundamental quantitative and qualitative research to assess an
issuer's credit quality, taking into account financial condition and
profitability, future capital needs, potential for change in rating, industry
outlook, the competitive environment and management ability. PIM may sell a
portfolio security when it believes the security no longer will contribute to
meeting the fund's investment objectives. PIM makes that determination based on
the same criteria it uses to select portfolio securities. In making these
portfolio decisions, PIM relies on the knowledge, experience and judgment of
its staff and the staff of its affiliates who have access to a wide variety of
research.

The fund may use financial leverage on an ongoing basis for investment purposes
by borrowing from banks through a revolving credit facility. Leverage creates
special risks not associated with unleveraged funds having a similar investment
objectives and policies. These include the possibility of higher volatility of
both the net asset value of the fund and the value of assets serving as asset
coverage for the preferred shares.
