               Pioneer Diversified High Income Trust | Annual Report | 4/30/18 1


President's Letter

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

Our view is that the first-quarter pause in the market's near-continuous upward
momentum over the previous 15 months, dating back to the final quarter of 2016,
presents an opportunity for investors to enter the market at healthier valuation
levels. We believe fundamentals are still quite positive, yet also believe that
caution is warranted given that the market remains vulnerable to corrections.
Some areas, such as growth stocks, appear expensive, but we do see opportunity
in value stocks, with prices supported by better corporate earnings due to the
recent tax reforms in the U.S. as well as robust, nominal gross domestic product
(GDP) growth. In fact, GDP growth in the U.S. rose to close to or better than 3%
over the final three quarters of 2017, and GDP growth in the first quarter of
2018 registered at 2.3%.

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

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

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

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

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

Portfolio Management Discussion | 4/30/18

In the following interview, Andrew Feltus, Charles Melchreit, Jonathan Sharkey,
and Chin Liu discuss the factors that affected the performance of Pioneer
Diversified High Income Trust during the 12-month period ended April 30, 2018.
Mr. Feltus, Managing Director, Co-Director of High Yield, and a portfolio
manager at Amundi Pioneer Asset Management, Inc. ("Amundi Pioneer"), Mr.
Melchreit*, Senior Managing Director, Deputy Head of Fixed Income, U.S., and a
portfolio manager at Amundi Pioneer, Mr. Sharkey, a senior vice president and a
portfolio manager at Amundi Pioneer, and Mr. Liu, Senior Vice President,
Director of Insurance-Linked Securities (ILS), and a portfolio manager at Amundi
Pioneer, were responsible for the day-to-day management of the Trust during the
12-month period.

Q     How did the Trust perform during the 12 months ended April 30, 2018?

A     Pioneer Diversified High Income Trust returned 4.58% at net asset value
      (NAV) and -2.82% at market price during the 12-month period ended April
      30, 2018. During the same 12-month period, the Trust's composite benchmark
      returned 4.79%.

      The Trust's composite benchmark is based on equal weights of the ICE Bank
      of America Merrill Lynch (ICE BofA ML) Global High Yield and Emerging
      Markets Plus (GHY & EMP) Index and the Standard & Poor's/Loan Syndications
      & Trading Association (S&P/LSTA) Leveraged Loan Index. Unlike the Trust,
      the composite benchmark does not use leverage. While the use of leverage
      increases investment opportunity, it also increases investment risk.

      During the same period, the average return (at market price) of the 50
      closed end funds in Morningstar's High Yield Closed End Bond Funds
      Category (which may or may not be leveraged) was 2.16%, and the average
      return (at NAV) of the 50 closed end funds in the same Morningstar
      category was 4.46%. Meanwhile, the average return (at market price) of the
      40 closed end funds in Morningstar's Bank Loan Closed End Funds Category
      (which may or may not be leveraged) was 3.07%, and the average return (at
      NAV) of the 40 closed end funds in the same Morningstar category was
      5.20%.

*     NOTE: Charles Melchreit was a portfolio manager of the Trust during the
      full 12-month period ended April 30, 2018. Mr. Melchreit departed from
      Amundi Pioneer effective June 8, 2018. Effective June 8, 2018, Mr. Feltus,
      Mr. Sharkey, Mr. Liu, and Lawrence R. Zeno, a vice president and a
      portfolio manager at Amundi Pioneer, are responsible for the day-to-day
      management of the Trust.

4 Pioneer Diversified High Income Trust | Annual Report | 4/30/18


      The shares of the Trust were selling at a 12.2% discount to NAV at the end
      of the period on April 30, 2018. Comparatively, the shares of the Trust
      were selling at a 5.5% discount to NAV on April 30, 2017.

      As of April 30, 2018, the 30-day SEC yield on the Trust's shares was
      8.15%**.

Q     How would you describe the investment environment in the global
      fixed-income markets during the 12-month period ended April 30, 2018?

A     Entering the period, credit-oriented areas of the bond market (bonds
      sensitive to credit risk rather than interest-rate risk) continued to be
      supported by positive global economic data, accommodative policy stances
      by leading overseas central banks, and the U.S. Federal Reserve System's
      (the Fed's) well-signaled, incremental approach towards interest-rate
      normalization as well as the tapering of its balance sheet.

      The U.S. economy posted gross domestic product (GDP) growth in the 3%
      range over the last three quarters of 2017, against a backdrop of robust
      corporate earnings and arguably full employment. The economies of Europe
      and Japan were comfortably in positive territory over that same period,
      while China continued to report economic growth in the 7% range.

      In October of 2017, the Fed began to taper its reinvestment of maturing
      Treasury and mortgage-backed security (MBS) positions. Because the Fed's
      plan to taper its balance sheet had been telegraphed well in advance, the
      actual launch date created little stir in the markets. U.S. credit-market
      sentiment received an additional boost as 2017 drew to a close with the
      passage of a tax reform package in the U.S. that included a lowering of
      the corporate tax rate and a window during which companies are permitted
      to accelerate the expensing of capital investments.

      While so-called "risk" markets opened 2018 with a positive tenor,
      volatility would soon come to the forefront. In January, U.S. employment
      data surprised to the upside, leading the market to revise inflation
      expectations higher and raising concerns that the Fed would feel compelled
      to accelerate the pace of its rate hikes. While sentiment around inflation
      stabilized fairly quickly, the markets received another jolt in March as
      the Trump administration announced its intention to impose tariffs on
      steel and aluminum as well as on a wide range of imports from China. The
      move raised the prospect of a trade war with the potential to undermine
      global economic growth, while leading indicators in Europe suggested that
      the recovery had peaked in the world's second-largest economic region.

      April saw U.S. Treasury yields embark on another upward leg in the wake of
      the release of the Fed's March meeting minutes, which pointed toward a
      consensus among committee members that U.S. inflation was safely headed

      toward its target and that there was, perhaps, room to raise the federal
      funds rate more rapidly than previously expected. The ongoing climb in
      crude oil prices, which broke through the $50 per barrel trading range in
      late 2017, fueled additional anxiety about inflation and interest rates,
      while also promising to at least partially offset the benefit to consumers
      from lower individual tax rates in the U.S. The firming outlook for higher
      U.S. interest rates led to a weakening in some of the less fundamentally
      sound emerging market bond markets and currencies.

      While fixed-income returns in general finished the 12-month period in
      negative territory, credit-oriented issues such as U.S. high-yield
      corporates, emerging markets corporates, and leveraged bank loans
      outperformed higher-quality, more interest-rate-sensitive market segments.

Q     What factors affected the Trust's performance during the 12-month period
      ended April 30, 2018?

A     As with other fixed-income categories, performance for high-yield bonds
      was constrained during the period by the rise in Treasury yields. However,
      the continued decline in high-yield default rates supported a narrowing in
      credit spreads that, combined with coupon income, resulted in a positive
      return for the asset class. (Credit spreads are commonly defined as the
      differences in yield between Treasuries and other types of fixed-income
      securities with similar maturities.)

      The Trust's security selection results within high yield added to
      performance over the period, with positive contributions led by a pair of
      the portfolio's utility holdings: Vistra Energy and NRG Energy. During the
      period, Vistra Energy finalized its acquisition of portfolio holding
      Dynegy. News of the completed merger boosted the newly combined company's
      performance and aided the Trust's returns. NRG benefited from a general
      recovery in the utilities sector, which was driven in part by the
      relatively volatile market environment that developed over the second half
      of the period. Valuation concerns regarding investments in high-growth
      market segments - such as information technology - and the potential
      income-generating ability of utilities-related investments were among the
      factors contributing to the sector's rally. In addition, the Trust's
      significant weighting in the energy sector contributed positively to
      returns. Among the portfolio's energy holdings, refiner Calumet Specialty
      Products and exploration-and-production companies WPX Energy and Halcon
      Resources were standout performers over the period. A position in the
      euro-denominated debt of drug company Valeant Pharmaceuticals also was a
      leading contributor to the Trust's performance, with improved sentiment
      driven by management's steps to reduce Valeant's debt burden and move to

6 Pioneer Diversified High Income Trust | Annual Report | 4/30/18


      a more sustainable business model. Another positive factor in the Trust's
      performance was the rise of the euro relative to the U.S. dollar during
      the period, which boosted the return of the portfolio's position.

      The Trust's position in leveraged bank loans provided the strongest
      absolute returns within the portfolio over the 12 months, even as the
      portfolio's underweight to its target loan allocation for the full
      reporting cycle acted as a constraint on relative returns. As with U.S.
      high-yield corporates, performance for the loan asset class benefited from
      a continued low default rate during the period. In addition, loans
      received interest from investors who were attracted to the floating-rate
      feature of bank loans in a rising-interest-rate environment.

      Finally, the portfolio's meaningful short-duration stance relative to the
      benchmark supported results, as U.S. Treasury yields moved higher over the
      12 months. (Duration is measure of the sensitivity of the price, or the
      value of principal, of a fixed-income investment to a change in interest
      rates, expressed as a number of years.)

      On the downside, the portfolio's exposure to the debt of PetSmart held
      back the Trust's results, as investor concerns over competition from
      online retailers weighed on the bond price. Exposure to wireline companies
      Windstream Communications and Frontier Communications also detracted from
      the Trust's performance.

      While the Trust's security selection results within the insurance-linked
      security (ILS) asset category were positive, the portfolio's overall
      exposure to ILS detracted modestly from relative performance for the 12
      months. ILS are used by property-and-casualty insurers to help mitigate
      some of the risk associated with claims payouts in the event of a major
      disaster. Returns for ILS issues suffered in late 2017 in the wake of a
      number of catastrophes, including three severe hurricanes which hit the
      U.S. mainland and Puerto Rico, two major earthquakes which shook western
      Mexico, and California's worst wild fires on record. Those events, all of
      which occurred over a relatively short time period, resulted in a 12-year
      high in natural-disaster-related damage claims in the global insurance
      industry, while costing the industry $110 billion in estimated losses.
      While the ILS market rebounded to a degree in early 2018, it nonetheless
      lagged the high-yield corporate, emerging markets corporate, and bank loan
      segments over the full 12 months.

      Investing in ILS has been part of the portfolio's diversification*
      strategy since the Trust's inception in May 2007, and the 12 months ended
      April 30, 2018, marked the first annual reporting period during which ILS
      exposure detracted from the Trust's performance relative to the benchmark.

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

               Pioneer Diversified High Income Trust | Annual Report | 4/30/18 7


Q     How did the level of leverage in the Trust change over the 12-month period
      ended April 30, 2018?

A     The Trust employs leverage through a credit agreement. (See Note 8 to the
      Financial Statements.)

      At the end of the 12-month period on April 30, 2018, 31.0% of the Trust's
      total managed assets were financed by leverage, compared with 27.9% of the
      Trust's total managed assets financed by leverage at the start of the
      period on May 1, 2017. The Trust's leverage ratio rose primarily due to an
      increased absolute amount of funds borrowed by the Trust early in the
      twelve-month period, and marginally due to the depreciation of the value
      of the Trust's holdings.

Q     Did the Trust's distributions** to shareholders change during the 12-month
      period ended April 30, 2018?

A     The Trust's distributions declined during the period as the portfolio's
      newer investments in high-yield bonds and bank loans tended to pay yields
      that were lower than older investments issued when interest rates were
      higher. The Trust has drawn on accumulated net investment income in paying
      the Trust's distributions in recent periods, and these reserves may be
      depleted over time.

Q     Did the Trust invest in any derivative securities during the 12-month
      period ended April 30, 2018? If so, did the derivatives have a notable
      effect on benchmark-relative performance?

A     We invested the portfolio in forward foreign currency contracts during the
      period to help manage the risk of the portfolio's exposures to foreign
      currencies. The contracts had a small negative impact on the Trust's
      benchmark-relative results given the rise in the euro relative to the U.S.
      dollar over the 12 months.

Q     What is your investment outlook?

A     In our view, fundamentals remain supportive of credit-oriented segments of
      the market. Economic growth and corporate earnings remain strong,
      unemployment is low, wages have been trending modestly higher, and
      consumer balance sheets are sound in aggregate. That backdrop is also a
      positive for corporate profitability, which should help keep default rates
      low.

      At the same time, credit-asset valuations are relatively high, as
      reflected in meaningfully tight spreads by historical standards. In
      addition, after an extended period of seeing risk assets more or less
      grind steadily higher, volatility appears to have returned to the markets,
      driven in large part by speculation over the pace of the Fed's
      interest-rate hikes as well as

**    Distributions are not guaranteed.

      geopolitical uncertainty. The markets will be watching closely for any
      data - such as accelerating wage growth - that could signal the potential
      for higher inflation and thus spur the Fed to increase its benchmark rate
      more rapidly than currently anticipated.

      Given that backdrop, we are being cautious in adding credit risk to the
      Trust's portfolio. In addition, we are maintaining a meaningfully below-
      benchmark duration in order to keep the Trust positioned to take advantage
      of any rise in market interest rates, or a widening of credit spreads,
      that could result in valuation opportunities.

Please refer to the Schedule of Investments on pages 14-48 for a full listing of
Trust securities.

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

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

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.

Interest rates in the U.S. recently have been historically low, so the Trust
faces a heightened risk that interest rates may rise. A general rise in interest
rates could adversely affect the price and liquidity of fixed income securities.

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.

               Pioneer Diversified High Income Trust | Annual Report | 4/30/18 9


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.

Certain securities in which the Trust invests, including floating rate loans,
once sold, may not settle for an extended period (for example, several weeks or
even longer). The Trust will not receive its sale proceeds until that time,
which may constrain the Trust's ability to meet its obligations.

Insurance-linked securities may include event-linked bonds (also known as
insurance-linked bonds or catastrophe bonds). The return of principal and the
payment of interest on insurance-linked securities are contingent on the non-
occurrence of a predefined "trigger" event that leads to physical or economic
loss, such as a hurricane or an aerospace catastrophe.

These risks may increase share price volatility.

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

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

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

Shares of closed-end funds, unlike open-end funds, are not continuously offered.
There is a one-time public offering and, once issued, shares of closed-end funds
are bought and sold in the open market through a stock exchange and frequently
trade at prices lower than their NAV. NAV per 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 ICE BofA ML GHY & EMP 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 S&P/LSTA
Leveraged Loan Index provides broad and comprehensive total return metrics of
the U.S. universe of syndicated term loans.

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.

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.

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

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

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

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

              Pioneer Diversified High Income Trust | Annual Report | 4/30/18 55


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

A.    Security Valuation

      The net asset value of the Trust is computed once daily, on each day the
      New York Stock Exchange ("NYSE") is open, as of the close of regular
      trading on the NYSE.

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

      Loan interests are valued in accordance with guidelines established by the
      Board of Trustees at the mean between the last available bid and asked
      prices from one or more brokers or dealers as obtained from Loan Pricing
      Corporation, an independent third party 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 or catastrophe bonds are valued at the bid price
      obtained from an independent third party pricing service. Other insurance
      linked securities (including sidecars, collateralized reinsurance and
      industry loss warranties) 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 estimated value of the instrument.

      Equity securities that have traded on an exchange are valued by using 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

56 Pioneer Diversified High Income Trust | Annual Report | 4/30/18


      prices are not available, generally are valued using the mean between the
      last bid and asked prices or, if both last bid and asked prices are not
      available, at the last quoted bid price. Last sale and bid and asked
      prices are provided by independent third party pricing services. In the
      case of equity securities not traded on an exchange, prices are typically
      determined by independent third party pricing services using a variety of
      techniques and methods.

      The value of foreign securities is translated in U.S. dollars based on
      foreign currency exchange rate quotations supplied by a third party
      pricing source. Trading in non-U.S. equity securities is substantially
      completed each day at various times prior to the close of the NYSE. The
      values of such securities used in computing the net asset value of the
      Trust's shares are determined as of such times. The Trust may use a fair
      value model developed by an independent pricing service to value non-U.S.
      equity securities.

      Option contracts are generally valued at the mean between the last bid and
      ask prices on the principal exchange where they are traded.
      Over-the-counter ("OTC") options and options on swaps ("swaptions") are
      valued using prices supplied by independent pricing services, which
      consider such factors as market prices, market events, quotations from one
      or more brokers, Treasury spreads, yields, maturities and ratings, or may
      use a pricing matrix or other fair value methods or techniques to provide
      an estimated value of the security or instrument.

      Swap contracts, including interest rate swaps, caps and floors (other than
      centrally cleared swap contracts) are valued at the dealer quotations
      obtained from reputable International Swap Dealers Association members.
      Centrally cleared swaps are valued at the daily settlement price provided
      by the central clearing counterparty.

      Forward foreign currency contracts are valued daily using the foreign
      exchange rate or, for longer term forward contract positions, the spot
      currency rate, in each case provided by a third party pricing service.
      Contracts whose forward settlement date falls between two quoted days are
      valued by interpolation.

      Shares of open-end registered investment companies (including money market
      mutual funds) are valued at such funds' net asset value. Repurchase
      agreements are valued at par. Cash may include overnight time deposits at
      approved financial institutions.

      Securities or loan interests for which independent pricing services or
      broker-dealers are unable to supply prices or for which market prices
      and/or quotations are not readily available or are considered to be
      unreliable are valued by a fair valuation team comprised of certain
      personnel of the Adviser, pursuant to procedures adopted by the Trust's
      Board of Trustees. The Adviser's fair valuation team uses fair value
      methods approved by the

              Pioneer Diversified High Income Trust | Annual Report | 4/30/18 57


      Valuation Committee of the Board of Trustees. The Adviser's fair valuation
      team is responsible for monitoring developments that may impact fair
      valued securities and for discussing and assessing fair values on an
      ongoing basis, and at least quarterly, with the Valuation Committee of the
      Board of Trustees.

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

      At April 30, 2018, eleven securities were valued using fair value methods
      (in addition to securities valued using prices supplied by independent
      pricing services, broker-dealers or using a third party insurance pricing
      model) representing 5.8% of net assets. The value of these fair valued
      securities was $8,255,244.

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
      data in the exercise of reasonable diligence. 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 and net of income accrued on defaulted securities.

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

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

C.    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 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 on the Statement of Operations from the effects of changes in
      the market prices 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 is 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 contract
      and from unanticipated movements in the value of foreign currencies
      relative to the U.S. dollar.

      During year ended April 30, 2018, 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 notional value of contracts open during
      year ended April 30, 2018 was $5,451,876.

      Forward foreign currency contracts outstanding at April 30, 2018 are
      listed in the Schedule of Investments.

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 net taxable income and net realized capital gains,
      if any, to its shareowners. Therefore, no provision for federal Income
      taxes is required. As of April 30, 2018, the Trust did not accrue any
      interest or penalties with respect to uncertain tax positions, which, if
      applicable, would be recorded as

              Pioneer Diversified High Income Trust | Annual Report | 4/30/18 59


      an income tax expense on the Statement of Operations. Tax returns filed
      within the prior three years remain subject to examination by federal and
      state tax authorities.

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

      At April 30, 2018, the Trust reclassified $21,948,862 to decrease paid-in
      capital, $125,536 to decrease distributions in excess of net investment
      income and $21,823,326 to decrease accumulated net realized loss on
      investments to reflect permanent book/tax differences. These adjustments
      have no impact on the net assets or results of operations.

      At April 30, 2018, the Trust was permitted to carry forward $2,365,189 of
      short-term capital losses and $29,055,262 of long-term capital losses
      without limitation. Additionally, at April 30, 2018, the Trust had a net
      capital loss carryforward of $1,249,417 which will expire in 2019 if not
      utilized. Since unlimited losses are required to be used first, loss carry
      forwards that are subject to expiration may be more likely to expire
      unused.

      Capital loss carryforward not utilized and expired in 2018 amounts to
      $21,948,862.

      The tax character of distributions paid to shareowners during the years
      ended April 30, 2018 and April 30, 2017 were as follows:



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

      The following shows the components of distributable earnings (losses) on a
      federal income tax basis at April 30, 2018:

      --------------------------------------------------------------------------
                                                                
      Distributable earnings:
      Undistributed ordinary income                                $    644,023
      Capital loss carryforward                                     (32,669,868)
      Other book/tax temporary differences                           (1,973,057)
      Unrealized appreciation                                         4,320,661
      --------------------------------------------------------------------------
          Total                                                    $(29,678,241)
      ==========================================================================


      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.

F.    Insurance Linked Securities ("ILS")

      The Trust invests in event-linked bonds. Event-linked bonds are floating
      rate debt obligations for which the return of principal and the payment of
      interest are contingent on the non-occurrence of a pre-defined "trigger"
      event, such as a hurricane or an earthquake of a specific magnitude. The
      trigger event's magnitude may be based on losses to a company or industry,
      industry indexes or readings of scientific instruments, or may be based on
      specified actual losses. If a trigger event occurs, as defined within the
      terms of an event-linked bond, the Trust may lose a portion or all of its
      accrued interest and/or principal invested in such event-linked bond. The
      Trust is entitled to receive principal and interest payments so long as no
      trigger event occurs of the description and magnitude specified by the
      instrument. In addition to the specified 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 ILS may include special purpose vehicles
      ("SPVs") or similar instruments structured to comprise a portion of a
      reinsurer's catastrophe-oriented business, known as quota share
      instruments (sometimes referred to as reinsurance sidecars), or to provide
      reinsurance relating to specific risks to insurance or reinsurance
      companies through a collateralized instrument, known as collateralized
      reinsurance. Structured reinsurance investments also may include industry
      loss warranties ("ILWs"). A traditional ILW takes the form of a bilateral
      reinsurance contract, but there are also products that take the form of
      derivatives, collateralized structures, or exchange traded instruments.

              Pioneer Diversified High Income Trust | Annual Report | 4/30/18 61


      Structured reinsurance investments, including quota share instruments,
      collateralized reinsurance investments and ILWs, generally are subject to
      the same risks as event-linked bonds. In addition, where the instruments
      are based on the performance of underlying reinsurance contracts, the
      Trust has limited transparency into the individual underlying contracts,
      and therefore must rely upon the risk assessment and sound underwriting
      practices of the issuer. Accordingly, it may be more difficult for the
      Adviser to fully evaluate the underlying risk profile of the Trust's
      structured reinsurance investments, and therefore the Trust's assets are
      placed at greater risk of loss than if the Adviser had more complete
      information. Structured reinsurance instruments generally will be
      considered illiquid securities by the Trust. These securities may be
      difficult to purchase, sell or unwind. Illiquid securities also may be
      difficult to value. If the Trust is forced to sell an illiquid asset, the
      Trust may be forced to sell at a loss.

G.    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 on the Statement of Assets and Liabilities as an
      investment. All premiums are marked-to-market daily, and any unrealized
      appreciation or depreciation is recorded on 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 on 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 option contracts is limited to the premium
      originally paid. The average value of purchased options contracts open
      during the year ended April 30, 2018 was $0. Purchased option contracts
      outstanding at April 30, 2018 are listed within the Schedule of
      Investments.

62 Pioneer Diversified High Income Trust | Annual Report | 4/30/18


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

      The Trust invests in below investment grade (high yield) debt securities,
      floating rate loans and insurance-linked securities. 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 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 may be less liquid and more difficult to value, especially
      during periods of economic uncertainty or change, than higher rated debt
      securities. Certain securities in which the Trust invests, including
      floating rate loans, once sold, may not settle for an extended period (for
      example, several weeks or even longer). The Trust will not receive its
      sale proceeds until that time, which may constrain the Trust's ability to
      meet its obligations. 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
      irregular trading activity and extended settlement periods. The Trust's
      investments in certain foreign markets or countries with limited
      developing markets may subject the Trust to a greater degree of risk than
      in a developed market. These risks include disruptive political or
      economic conditions and the possible imposition of adverse governmental
      laws or currency exchange restrictions. The Trust may invest up to 50% of
      its total assets in illiquid securities. Illiquid securities are
      securities that cannot be disposed of by the Trust within seven days in
      the ordinary course of business at approximately the amounts which the
      Trust values the securities.

              Pioneer Diversified High Income Trust | Annual Report | 4/30/18 63


      Interest rates in the U.S. recently have been historically low, so the
      Trust faces a heightened risk that interest rates may rise. A general rise
      in interest rates could adversely affect the price and liquidity of fixed
      income securities.

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

I.    Repurchase Agreements

      Repurchase agreements are arrangements under which the Trust purchases
      securities from a broker-dealer or a bank, called the counterparty, upon
      the agreement of the counterparty to repurchase the securities from the
      Trust at a later date, and at a specific price, which is typically higher
      than the purchase price paid by the Trust. The securities purchased serve
      as the Trust's collateral for the obligation of the counterparty to
      repurchase the securities. The value of the collateral, including accrued
      interest, is required to be equal to or in excess of the repurchase price.
      The collateral for all repurchase agreements is held in safekeeping in the
      customer-only account of the Trust's custodian or a subcustodian of the
      Trust. The Adviser is responsible for determining that the value of the
      collateral remains at least equal to the repurchase price. In the

64 Pioneer Diversified High Income Trust | Annual Report | 4/30/18


      event of a default by the counterparty, the Trust is entitled to sell the
      securities, but the Trust may not be able to sell them for the price at
      which they were purchased, thus causing a loss to the Trust. Additionally,
      if the counterparty becomes insolvent, there is some risk that the Trust
      will not have a right to the securities, or the immediate right to sell
      the securities. Open repurchase agreements as of April 30, 2018 are
      disclosed in the Trust's Schedule of Investments.

J.    Credit Default Swap Contracts

      A credit default swap is a contract between a buyer of protection and a
      seller of protection against a pre-defined credit event on an underlying
      reference obligation, which may be a single security or a basket or index
      of securities. The Trust may buy or sell credit default swap contracts to
      seek to increase the Trust's income, or to attempt to hedge the risk of
      default on portfolio securities. A credit default swap index is used to
      hedge risk or take a position on a basket of credit entities or indices.

      As a seller of protection, the Trust would be required to pay the notional
      (or other agreed-upon) value of the referenced debt obligation to the
      counterparty in the event of a default by a U.S. or foreign corporate
      issuer of a debt obligation, which would likely result in a loss to the
      Trust. In return, the Trust would receive from the counterparty a periodic
      stream of payments during the term of the contract provided that no event
      of default occurred. The maximum exposure of loss to the seller would be
      the notional value of the credit default swaps outstanding. If no default
      occurs, the Trust would keep the stream of payments and would have no
      payment obligation. The Trust may also buy credit default swap contracts
      in order to hedge against the risk of default of debt securities, in which
      case the Trust would function as the counterparty referenced above.

      As a buyer of protection the Trust makes an upfront or periodic payment to
      the protection seller in exchange for the right to receive a contingent
      payment. An upfront payment made by the Trust, as the protection buyer, is
      recorded as a component of "Swap contracts, at value" on the Statement of
      Assets and Liabilities. Periodic payments received or paid by the Trust
      are recorded as realized gains or losses on the Statement of Operations.

      Credit default swap contracts are marked-to-market daily using valuations
      supplied by independent sources and the change in value, if any, is
      recorded within the "Swap contracts, at value" line item on the Statement
      of Assets and Liabilities. Payments received or made as a result of a
      credit event or upon termination of the contract are recognized, net of
      the appropriate amount of the upfront payment, as realized gains or losses
      on the Statement of Operations.

              Pioneer Diversified High Income Trust | Annual Report | 4/30/18 65


      Credit default swap contracts involving the sale of protection may involve
      greater risks than if the Trust had invested in the referenced debt
      instrument directly. Credit default swap contracts are subject to general
      market risk, liquidity risk, counterparty risk and credit risk. If the
      Trust is a protection buyer and no credit event occurs, it will lose its
      investment. If the Trust is a protection seller and a credit event occurs,
      the value of the referenced debt instrument received by the Trust,
      together with the periodic payments received, may be less than the amount
      the Trust pays to the protection buyer, resulting in a loss to the Trust.

      Certain swap contracts that are cleared through a central clearinghouse
      are referred to as centrally cleared swaps. All payments made or received
      by the Trust are pursuant to a centrally cleared swap contracts with the
      central clearing party rather than the original counterparty. Upon
      entering into a centrally cleared swap contract, the Trust is required to
      make an initial margin deposit, either in cash or in securities. The daily
      change in value on open centrally cleared swap contracts is recorded as
      "Variation margin for centrally cleared swaps" on the Statement of Assets
      and Liabilities. Cash received from or paid to the broker related to
      previous margin movement is held in a segregated account at the broker and
      is recorded as either "Due from broker for swaps" or "Due to broker for
      swaps" on the Statement of Assets and Liabilities.

      The amount of cash deposited with the broker as collateral at April 30,
      2018 is recorded as "Swaps collateral" on the Statement of Assets and
      Liabilities.

      Open credit default swap contracts at April 30, 2018 are listed in the
      Schedule of Investments. The average notional value of credit default swap
      contracts open during the year ended April 30, 2018 was $117,372.

K.    Automatic Dividend Reinvestment Plan

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

66 Pioneer Diversified High Income Trust | Annual Report | 4/30/18


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

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

2. Management Agreement

The Adviser manages the Trust's portfolio. Management fees payable under the
Trust's Advisory Agreement with the Adviser are calculated daily at the annual
rate of 0.85% of the Trust's average daily managed assets. "Managed assets"
means (a) the total assets of the Trust, including any form of investment
leverage, minus (b) all accrued liabilities incurred in the normal course of
operations, which shall not include any liabilities or obligations attributable
to investment leverage obtained through (i) indebtedness of any type (including,
without limitation, borrowing through a credit facility or the issuance of debt
securities), (ii) the issuance of preferred stock or other similar preference
securities, and/or (iii) any other means. For the year ended April 30, 2018 the
net management fee was 0.85% of the Trust's average daily managed assets, which
was equivalent to 1.22% of the Trust's average daily net assets.

              Pioneer Diversified High Income Trust | Annual Report | 4/30/18 67


In addition, under the management and administration agreements, certain other
services and costs are paid by the Adviser and reimbursed by the Trust. At April
30, 2018, $23,412 was payable to the Adviser related to management costs,
administrative costs and certain other services is included in "Due to
affiliates" on the Statement of Assets and Liabilities.

3. Transfer Agent

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

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

4. Assets and Liabilities Offsetting

The Trust has entered into an International Swaps and Derivatives Association,
Inc. Master Agreement (ISDA Master Agreement) or similar agreement with
substantially all its derivative counterparties. An ISDA Master Agreement is a
bilateral agreement between the Trust and a counterparty that governs the
trading of certain OTC derivatives and typically contains, among other things,
close-out and set-off provisions which apply upon the occurrence of an event of
default and/or a termination event as defined under the relevant ISDA Master
Agreement. The ISDA Master Agreement may also give a party the right to
terminate all transactions traded under such agreement if, among other things,
there is deterioration in the credit quality of the other party. Upon an event
of default or a termination of the ISDA Master Agreement, the non-defaulting
party has the right to close out all transactions under such agreement and to
net amounts owed under each transaction to determine one net amount payable by
one party to the other. The right to close out and net payments across all
transactions under the ISDA Master Agreement could result in a reduction of the
Trust's credit risk to its counterparty equal to any amounts payable by the
Trust under the applicable transactions, if any. However, the Trust's right to
setoff may be restricted or prohibited by the bankruptcy or insolvency laws of
the particular jurisdiction to which each specific ISDA of each counterparty is
subject.

The collateral requirements for derivatives transactions under an ISDA Master
Agreement are governed by a credit support annex to the ISDA Master Agreement.
Collateral requirements are generally determined at the close of business each
day and are typically based on changes in market values for each transaction
under an ISDA Master Agreement and netted into one amount for such agreement.
Generally, the amount of collateral due from or to a counterparty is subject to
threshold (a minimum transfer amount) before a transfer is required, which may
vary by counterparty. Collateral pledged for

68 Pioneer Diversified High Income Trust | Annual Report | 4/30/18


the benefit of the Trust and/or counterparty is held in segregated accounts by
the Trust's custodian and cannot be sold, re-pledged, assigned or otherwise
used while pledged. Cash that has been segregated to cover the Trust's
collateral obligations, if any, will be reported separately on the Statement of
Assets and Liabilities as "Swaps collateral". Securities pledged by the Trust as
collateral, if any, are identified as such in the Schedule of Investments.

Financial instruments subject to an enforceable master netting agreement such
as an ISDA Master Agreement have not been offset on the Statement of Assets
and Liabilities. The following charts show gross assets and liabilities of the
Trust as of April 30, 2018:

5. Additional Disclosures about Derivative Instruments and Hedging Activities

The Trust's use of derivatives may enhance or mitigate the Trust's exposure to
the following risks:

Interest rate risk relates to the fluctuations in the value of interest-bearing
securities due to changes in the prevailing levels of market interest rates.

Credit risk relates to the ability of the issuer of a financial instrument to
make further principal or interest payments on an obligation or commitment that
it has to the Trust.

Foreign exchange rate risk relates to fluctuations in the value of an asset or
liability due to changes in currency exchange rates.

              Pioneer Diversified High Income Trust | Annual Report | 4/30/18 69


Equity risk relates to the fluctuations in the value of financial instruments as
a result of changes in market prices (other than those arising from interest
rate risk or foreign exchange rate risk), whether caused by factors specific to
an individual investment, its issuer, or all factors affecting all instruments
traded in a market or market segment.

Commodity risk relates to the risk that the value of a commodity or commodity
index will fluctuate based on increases or decreases in the commodities market
and factors specific to a particular industry or commodity.

The fair value of open derivative instruments (not considered to be hedging
instruments for accounting disclosure purposes) by risk exposure at April 30,
2018 was as follows:

The Trust is required to maintain 300% asset coverage with respect to amounts
outstanding under the credit agreement. Asset coverage is calculated by
subtracting the Trust's total liabilities not including any bank loans and
senior securities, from the Trust's total assets and dividing such amount by the
principal amount of the borrowing outstanding.

Report of Independent Registered Public Accounting Firm

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

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities of Pioneer
Diversified High Income Trust (the "Trust"), including the schedule of
investments, as of April 30, 2018, and the related statements of operations,
changes in net assets, and the financial highlights for the year then ended and
the related notes and the financial highlights for the year ended April 30, 2014
(collectively referred to as the "financial statements"). The statement of
changes in net assets for the year ended April 30, 2017 and the financial
highlights for the periods ended April 30, 2015, April 30, 2016 and April 30,
2017 were audited by another independent registered public accounting firm whose
report, dated June 19, 2017, expressed an unqualified opinion on the statement
of changes in net assets and those financial highlights. In our opinion, the
financial statements present fairly, in all material respects, the financial
position of Pioneer Diversified High Income Trust at April 30, 2018, the results
of its operations, the changes in its net assets, and the financial highlights
for the year ended and the financial highlights for the year ended April 30,
2014, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

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

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

              Pioneer Diversified High Income Trust | Annual Report | 4/30/18 73


Our audits included performing procedures to assess the risks of material
misstatement of the financial statements, whether due to error or fraud, and
performing procedures that respond to those risks. Such procedures included
examining, on a test basis, evidence regarding the amounts and disclosures in
the financial statements. Our procedures included confirmation of securities
owned as of April 30, 2018, by correspondence with the custodian and brokers or
by other appropriate auditing procedures where replies from brokers were not
received. Our audits also included evaluating the accounting principles used and
significant estimates made by management, as well as evaluating the overall
presentation of the financial statements. We believe that our audits provide a
reasonable basis for our opinion.

                                                           /s/ Ernst & Young LLP

ADDITIONAL INFORMATION

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.

During the period there were no changes in the persons who are primarily
responsible for the day-to-day management of the Trust's portfolio. Charles
Melchreit, a portfolio manager of the Trust during the 12-month period ended
April 30, 2018, departed from Amundi Pioneer effective June 8, 2018. Andrew
Feltus, Jonathan Sharkey and Chin Liu continue to be responsible for the day-
to-day management of the Trust. In addition, effective June 8, 2018, Lawrence R.
Zeno, a vice president and portfolio manager at Amundi Pioneer, became a
portfolio manager of the Trust. Lawrence Zeno is a Vice President and Portfolio
Manager based in Chicago. His primary responsibility is the CMBS sector. He also
manages the residential NPL allocation and co-manages the legacy sub-prime
sector. Previously, Lawrence was a Partner and Senior Manager of Trading at
Asset Allocation & Management Company, where he also managed the CMBS and RMBS
sectors. He holds a B.A. from Northwestern University and has been in the
investment industry since 1989. Lawrence Zeno joined Amundi Pioneer in 2001.

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 shares
in the open market.

Change in Independent Registered Public Accounting Firm

Prior to July 3, 2017 Pioneer Investment Management, Inc. (the "Adviser"), the
Trust's investment adviser, was an indirect, wholly owned subsidiary of
UniCredit S.p.A. ("UniCredit"). On that date, UniCredit completed the sale of
its Pioneer Investments business, which includes the Adviser, to Amundi (the
"Transaction"). As a result of the Transaction, the Adviser became an indirect,
wholly owned subsidiary of Amundi. Amundi is controlled by Credit Agricole S.A.
Amundi is headquartered in Paris, France, and, as of September 30, 2016, had
more than $1.1 trillion in assets under management worldwide. Deloitte & Touche
LLP ("D&T"), the Trust's previous independent registered public accounting firm,
informed the Audit Committee and the Board that it would no longer be
independent with respect to the Trust upon the completion of the Transaction as
a result of certain services being provided to Amundi and Credit Agricole, and,
accordingly, that it intended to resign as the Trust's independent registered
public accounting firm upon the completion of the Transaction. D&T's resignation
was effective on July 3, 2017, when the Transaction was completed.

              Pioneer Diversified High Income Trust | Annual Report | 4/30/18 75


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

Effective immediately following the completion of the Transaction on July 3,
2017, the Board, acting upon the recommendation of the Audit Committee, engaged
a new independent registered public accounting firm, Ernst & Young LLP ("EY"),
for the Trust's fiscal year ended April 30, 2018.

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

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

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

                  SECTION I - POLICY PURPOSE AND APPLICABILITY

The Pioneer Funds recognize the importance of maintaining the independence of
their outside auditors. Maintaining independence is a shared responsibility
involving Amudi Pioneer Asset Management, Inc, the audit committee and
the independent auditors.

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

Approval of a service in accordance with this policy for a Fund shall also
constitute approval for any other Fund whose pre-approval is required pursuant

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 2018 and 2017, 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 $10,115
payable to Ernst & Young LLP for the year ended
April 30, 2018 and $9,904 payable to Deloitte & Touche LLP
for the year ended April 30, 2017.


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

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


                                       0


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

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

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

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

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


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


                                       1


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

o QUANTITATIVE INVESTMENT PERFORMANCE. The quantitative investment performance
  calculation is based on pre-tax investment performance of all of the
  accounts managed by the portfolio manager (which includes the fund and any
  other accounts managed by the portfolio manager) over a one-year period (20%
  weighting) and four-year period (80% weighting), measured for periods ending
  on December 31. The accounts, which include the fund, are ranked against a
  group of mutual funds with similar investment objectives and investment
  focus (60%) and a broad-based securities market index measuring the
  performance of the same type of securities in which the accounts invest
  (40%), which, in the case of the fund, is the 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 AMUNDI PIONEER RESULTS AND BUSINESS LINE RESULTS. Amundi Pioneer's financial
  performance, as well as the investment performance of its investment
  management group, affect a portfolio manager's actual bonus by a leverage
  factor of plus or minus (+/-) a predetermined percentage.

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

Certain portfolio managers participate in other programs designed to reward and
retain key contributors. Portfolio managers also may participate in a deferred
compensation program, whereby deferred amounts are invested in one or more
Pioneer funds.

  - 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

principal financials officers, or persons performing similar functions,
regarding the effectiveness of the registrant's disclosure

based on the evaluation of these controls and procedures required by Rule
30a-3(b) under the Act (17 CFR 270.30(a)-3(b) and Rules 13a-15(b) or 15d-15(b)
under the Exchange Act (17 CFR 240.13a-15(b) or 240.15d-15(b)).

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

occured during the second fiscal quarter of the period covered by this report
that has materially affected, or is reasonably likely to materially affect,
the registrant's internal control over financial reporting.

There were no significant changes in the
registrant's internal control over financial

reporting.

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

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