President's Letter

Since 1928, active portfolio management based on in-depth, fundamental
research, has been the foundation of Amundi Pioneer's investment approach. We
believe an active management investment strategy is a prudent approach to
investing, especially during periods of market volatility, which can result
from any number of risk factors, including slow U.S. economic growth, rising
interest rates, and geopolitical factors. Of course, in today's global economy,
risk factors extend well beyond U.S. borders. In fact, it's not unusual for
political and economic issues on the international front to cause or contribute
to volatility in U.S. markets.

At Amundi Pioneer, each security under consideration is researched by our team
of experienced investment professionals, who visit companies and meet with
their management teams. At the end of this research process, if we have
conviction in a company's business model and management team, and regard the
security as a potentially solid investment opportunity, an Amundi Pioneer
portfolio manager makes an active decision to invest in that security. The
portfolio resulting from these decisions represents an expression of his or her
convictions, and strives to balance overall risk and return opportunity.

As an example, the Standard & Poor's 500 Index -- the predominant benchmark for
many U.S. Large-Cap Core Equity funds -- has 500 stocks. An Amundi Pioneer
portfolio manager chooses to invest in only those companies that he or she
believes can offer the most attractive opportunities to pursue the fund's
investment objective, thus potentially benefiting the fund's shareowners. This
process results in a portfolio that does not own all 500 stocks, but a much
narrower universe.

The same active decision to invest in a company is also applied when we decide
to sell a security, either due to changing fundamentals, valuation concerns, or
market risks. We apply this active decision-making across all of our equity,
fixed-income, and global portfolios.

Today, as investors, we have many options. It is our view that active
management can serve shareholders well not only when markets are thriving, but
also during periods of market volatility and uncertainty, thus making it a
compelling investment choice. As you consider the many choices today, 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.

Portfolio Management Discussion | 4/30/19

In the following interview, Andrew Feltus, Jonathan Sharkey, Chin Liu, and
Lawrence Zeno discuss the factors that affected the performance of Pioneer
Diversified High Income Trust during the 12-month period ended April 30, 2019.
Mr. Feltus, Managing Director, Co-Director of High Yield, and a portfolio
manager at Amundi Pioneer Asset Management, Inc. (Amundi Pioneer), Mr. Sharkey,
a senior vice president and a portfolio manager at Amundi Pioneer, Mr. Liu,
Managing Director, Director of Insurance-Linked Securities (ILS) and
Quantitative Research, and a portfolio manager at Amundi Pioneer, and Mr. Zeno,
a vice president and a portfolio manager at Amundi Pioneer, are responsible for
the day-to-day management of the Trust.

Q     How did the Trust perform during the 12 months ended April 30, 2019?

A     Pioneer Diversified High Income Trust returned 2.58% at net asset value
      (NAV) and 3.95% at market price during the 12-month period ended April 30,
      2019. During the same 12-month period, the Trust's composite benchmark
      returned 3.93% at NAV. 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 Crossover Country Corporate and Government (GHY/CCC & G) 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 NAV of the 42 closed end
      funds in Morningstar's High Yield Closed End Bond Funds Category (which
      may or may not be leveraged) was 5.48%, and the average return at market
      price of the 42 closed end funds in the same Morningstar category was
      8.24%. Meanwhile, the average return at NAV of the 43 closed end funds in
      Morningstar's Bank Loan Closed End Funds Category (which may or may not be
      leveraged) was 3.26%, and the average return at market price of the 43
      closed end funds in the same Morningstar category was 0.63%.

      The shares of the Trust were selling at a 11.1% discount to NAV at the end
      of the period on April 30, 2019. Comparatively, the shares of the Trust
      were selling at a 12.2% discount to NAV on April 30, 2018.

      As of April 30, 2019, the 30-day SEC yield on the Trust's shares was
      7.51%*

*     The 30-day SEC yield is a standardized formula that is based on the
      hypothetical annualized earning power (investment income only) of the
      Trust's portfolio securities during the period indicated.

Q     How would you describe the investment environment in the global
      fixed-income markets during the 12-month period ended April 30, 2019?

A     For most of the period, investors focused strongly on the U.S. Federal
      Reserve System's (the Fed's) monetary policy. Messaging from the Fed
      entering the period in May 2018 appeared to indicate a consensus among
      Federal Open Market Committee members that U.S. inflation was headed
      toward the 2% target and that there was perhaps room to raise the
      benchmark federal funds rate more rapidly than previously expected. The
      ongoing climb in crude oil prices, which broke out of the $50 a barrel
      trading range in late 2017, fueled additional anxiety among investors
      about inflation and interest rates, while also promising to largely offset
      the benefit to consumers from lower individual U.S. tax rates that went
      into effect in January 2018.

      The firming outlook for higher U.S. interest rates was a contributing
      factor in a significant weakening in some of the less fundamentally sound
      emerging markets bond market segments and currencies, with Turkey and
      Argentina feeling the biggest negative effects. The euro also declined
      meaningfully versus the U.S. dollar (USD), as weak regional growth left
      the European Central Bank (ECB) to maintain a zero-interest-rate policy.

      At its September 2018 meeting, the Fed implemented its third 0.25% rate
      hike of the calendar year, while signaling the likelihood of another
      increase in December. October 2018 saw U.S. high-yield bonds come under
      pressure alongside the sharpest one-month decline in U.S. equity markets
      since September 2011 (as measured by the Standard & Poor's 500 Index).
      Investor sentiment for riskier assets also declined that month in
      conjunction with an underwhelming start to the third-quarter corporate
      earnings season, especially with respect to technology companies, a
      further deterioration in U.S.-China trade relations, softening economic
      growth overseas, Italy's budget crisis, and political uncertainty.

      In mid-December, the Fed met expectations and raised its short-term rate
      target to the 2.25% to 2.50% range, the fourth increase in calendar year
      2018, while noting the potential for additional rate hikes in 2019. In
      combination with signs of slowing global economic growth and yet another
      setback in the "Brexit" negotiations in the United Kingdom, concerns that
      the Fed would overshoot on interest rates led to a spike in volatility in
      the market for riskier assets. December 2018 saw the 10-year U.S. Treasury
      yield decline from 3.01% to 2.69%, as investors sought a safe haven from
      the market turmoil. Energy-related issues also declined sharply as crude
      oil prices plunged over the fourth quarter, mainly due to concerns about a
      weaker demand outlook and higher-than-expected supply driven in part by a
      loosening of U.S. sanctions on Iran.

               Pioneer Diversified High Income Trust | Annual Report | 4/30/19 5



      Bank loans also struggled in late 2018, as loan prices suffered due to
      retail investors removing assets from loan mutual funds. Institutional
      demand for loans was light as well, given a drop-off in collateralized
      loan obligation (CLO) formation following a record calendar year in terms
      of volume.

      Risk-oriented assets rebounded sharply in January of 2019, however, as the
      Fed pivoted on monetary policy and took on a less aggressive tone,
      announcing an early end to its balance-sheet reduction program while also
      indicating it would become more "data dependent" with regard to interest
      rates, thus putting further increases on hold, at least temporarily. In
      addition to the Fed's policy actions, weak economic data out of the euro
      zone and China led to renewed policy accommodations from both the ECB and
      the People's Bank of China. Modest progress on trade matters, a firming in
      oil prices, and positive corporate earnings reports also helped boost
      credit-market sentiment during the first quarter of 2019. While the
      overall pace of gains moderated and there was some interim market
      volatility over the final weeks of the period, credit-sensitive assets
      continued to outperform interest-rate-sensitive issues through the end of
      April.

Q     What factors affected the Trust's benchmark-relative performance during
      the 12-month period ended April 30, 2019?

A     The Trust's out-of-benchmark exposure to insurance-linked securities (ILS)
      detracted from benchmark-relative performance during the period. Returns
      for ILS issues, which are sponsored by property-and-casualty insurers to
      help mitigate the risk of having to pay claims in the wake of natural
      disasters, suffered after numerous claims-generating events occurred over
      the second half of 2018, including typhoons in Japan, hurricanes in the
      Southeastern U.S. and the Carolinas, and the worst California wildfire
      season on record. Investing in ILS has been part of our portfolio
      diversification** strategy since the Trust's inception in May 2007, and we
      continue to view exposure to the asset class, which features return
      streams that are uncorrelated with the performance of traditional credit
      markets, as helping to improve the Trust's long-term risk/reward profile.

      Despite the weak performance of bank loans in late 2018, the portfolio's
      relative underweight to loans also detracted from performance versus the
      Trust's custom benchmark, as the asset class rebounded over the final few
      months of the period and outperformed other asset classes such as ILS. The
      allocation to bank loans did provide a positive overall return for the
      period, as the asset class bounced back from its late-2018 slump,
      benefiting from a strong fundamental backdrop and continued low default
      rate. In addition, loans received a lot of interest early in the period
      from investors attracted to their floating-rate feature in a
      rising-interest-rate environment. As noted

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

6 Pioneer Diversified High Income Trust | Annual Report | 4/30/19



      earlier, the loan market was negatively affected in late 2018 by massive
      outflows from retail mutual fund investors, but recovered the bulk of
      those losses over the first four months of 2019.

      In terms of individual loans held in the portfolio, positive contributions
      to the Trust's benchmark-relative performance were led by exposure to the
      loans of Uniti. The company's spinoff as an infrastructure real estate
      investment trust from wireline service provider Windstream resulted in
      litigation that created uncertainty among market participants, but those
      concerns eased over the 12-month period and Uniti's loan prices benefited
      from the improved sentiment. Loans of beauty company Revlon and luxury
      retailer Neiman Marcus also contributed positively to the Trust's
      benchmark-relative performance during the period. Market sentiment towards
      Revlon received a boost from an improved sales outlook, while the prices
      of the Neiman Marcus loans benefited as the company rationalized its
      capital structure.

      Notable detractors from the Trust's benchmark-relative performance during
      the period included loans of Serta Simmons, as the mattress retailer
      experienced customer losses and deteriorating operational results. A pair
      of energy-related loans in the portfolio, for Gulf Finance and Gavilan
      Resources, also lagged and detracted from the Trust's relative returns due
      to the softening in oil prices witnessed in the fourth quarter of 2018.

      Another detractor from benchmark-relative performance during the period
      was the Trust's allocation to emerging markets bonds, particularly in
      Argentina. Within Argentina, the portfolio had some holdings which
      struggled as the peso plunged and spread widening for the country's
      sovereign debt negatively affected that market. (Credit spreads are
      commonly defined as the differences in yield between Treasuries and other
      types of securities with similar maturities.) In particular, the Trust's
      positions in Argentina's state-controlled energy company YPF, and the
      bonds of Argentine province Entre Rios detracted from relative results. On
      the other hand, the Trust's exposure to Brazil benefited relative
      performance, as investor sentiment with respect to that market
      strengthened following the presidential election. Positive contributions
      to performance in Brazil were led by the Trust's exposures to beef
      producer Marfrig Holdings and utility Light Servicio. In addition,
      benchmark-relative performance benefited from the Trust's overweighting of
      corporate bonds versus the more interest-rate-sensitive sovereign issues
      within the emerging markets.

      Within U.S. high-yield corporates, the Trust's overweight to energy
      detracted from benchmark-relative returns for the period. Among high-yield
      bond positions in the portfolio, the largest detractors from the Trust's
      relative performance included the debt of energy producers Sanchez Energy
      and Chaparral Energy. Performance within energy benefited from

               Pioneer Diversified High Income Trust | Annual Report | 4/30/19 7



      the portfolio's exposure to longer-duration pipeline issues, which are
      typically less sensitive to oil prices. Those holdings included the debt
      of Williams Companies and Enterprise Development. Outside of energy, the
      Trust's holdings of the bonds of Diebold Nixdorf hurt performance, as the
      multinational, point-of-sale technology company experienced weakening
      operating results.

      Finally, the portfolio's short-duration stance relative to the benchmark
      detracted from benchmark-relative results as U.S. Treasury yields moved
      lower over the 12 months. (Duration is a 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.)

Q     How did the level of leverage in the Trust change over the 12-month period
      ended April 30, 2019?

A     The Trust employs leverage through a credit agreement.

      At the end of the 12-month period on April 30, 2019, 31.1% of the Trust's
      total managed assets were financed by leverage, compared with 31.0% of the
      Trust's total managed assets financed by leverage at the start of the
      period on May 1, 2018. During the 12-month period, the Trust reduced the
      absolute amount of borrowed funds. The slight increase in the percentage
      of the Trust's total managed assets financed by leverage was the result of
      a reduction of the aggregate net asset value of the Trust's holdings.

Q     Did the Trust's distributions*** to shareholders change during the
      12-month period ended April 30, 2019?

A     No, the Trust's distributions remained stable throughout the 12-month
      period.

Q     Did the Trust invest in any derivative securities during the 12-month
      period ended April 30, 2019? If so, did the derivatives have a notable
      effect on performance?

A     We invested the portfolio in forward foreign currency contracts during the
      period to help hedge the risk of the Trust's exposures to foreign
      currencies. The contracts had a small positive impact on the Trust's
      benchmark-relative results, given the decline in the euro relative to the
      USD over the 12 months.

Q     What is your investment outlook?

A     In our view, credit fundamentals remain largely supportive for high-yield
      securities and other risk-oriented asset classes. The outlook for U.S.
      economic growth and corporate earnings remains positive. Unemployment is
      low, wages have been trending modestly higher, and consumer balance sheets
      are sound in aggregate. While economic growth in 2019 is expected to be in
      the modest 2% to 2.5% range, we believe that rate should be sufficient to
      maintain current fundamentals.

***   Distributions are not guaranteed.

8 Pioneer Diversified High Income Trust | Annual Report | 4/30/19



      Risks to the outlook include slowing economic growth overseas, as the
      economies of both China and Europe disappointed in 2018, leading to
      central-bank easing that could help conditions going forward. In addition,
      while the U.S.-China trade dispute does not appear to have weighed heavily
      on the global economy to date, any adverse development on that front would
      not be supportive of risk-market sentiment. The run-up to the 2020 U.S.
      presidential election also has the potential to blur the outlook.

      With regard to positioning, we had increased the Trust's exposure to bank
      loans and other floating-rate assets over the last year, but now that the
      Fed is leaning towards easing instead of further rate hikes, we are
      comfortable with adding fixed-rate securities to the portfolio. We expect
      loan default rates to remain low, but given the recent rally in credit
      spreads, we are not aggressively adding risk to the Trust's portfolio. The
      recent trends toward weaker loan covenants and the greater levels of
      leverage associated with newer loan issues give us pause. In this
      environment, we believe security selection will drive performance more
      than a step-down in credit quality.

      In broad terms, the Trust is overweight to the U.S. bond market versus
      Europe. We view high-yield valuations in Europe as attractive compared to
      U.S. valuations, but have maintained an essentially neutral portfolio
      positioning in the region, given the low absolute yields available.

      After two poor years, ILS pricing has been improving for investors. While
      the asset class may provide diversification benefits versus most
      fixed-income and equity asset classes, higher yields can potentially
      improve expected returns, although the risk of elevated claims payouts
      resulting from natural disasters remains unpredictable.

      We view current emerging markets valuations as essentially in line with
      historical averages, and the Trust remains underweight in the emerging
      markets, with a focus on corporates that are less interest-rate sensitive
      as compared with sovereign issues.

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.

               Pioneer Diversified High Income Trust | Annual Report | 4/30/19 9



When interest rates rise, the prices of debt securities held by the Trust will
generally fall. Conversely, when interest rates fall the prices of debt
securities held by the Trust generally will rise. Interest rates in the U.S.
recently have been historically low, but have begun to rise, and so the Trust
faces a heightened risk that interest rates may continue to increase.
Investments held by the Trust are subject to possible loss due to the financial
failure of the issuers of the underlying securities and the issuers' inability
to meet their debt obligations.

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

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

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

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 insurance-linked securities. The return of principal
and the right to additional payments from investments in 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.

Any information in this shareholder report regarding market or economic trends
or the factors influencing the Trust's historical or future performance are
statements of opinion as of the date of this report. Past performance is no
guarantee of future results.

Call 1-800-710-0935 or visit www.amundipioneer.com/us 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/CCC & G 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.

Various inputs are used in determining the value of the Trust's investments.
These inputs are summarized in the three broad levels below.

  Level 1 - quoted prices in active markets for identical securities.

  Level 2 - other significant observable inputs (including quoted prices for
            similar securities, interest rates, prepayment speeds, credit risks,
            etc.). See Notes to Financial Statements -- Note 1A.

  Level 3 - significant unobservable inputs (including the Trust's own
            assumptions in determining fair value of investments). See Notes to
            Financial Statements -- Note 1A.

The following is a summary of the inputs used as of April 30, 2019, in valuing

Notes to Financial Statements | 4/30/19

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.

Amundi Pioneer Asset Management, Inc., an indirect, wholly owned subsidiary of
Amundi and Amundi's wholly owned subsidiary, Amundi USA, Inc., serves as the
Trust's investment adviser (the "Adviser"). Amundi Pioneer Distributor, Inc.,
an affiliate of Amundi Pioneer Asset Management, Inc., serves as the Trust's
distributor (the "Distributor").

In August 2018, the Securities and Exchange Commission ("SEC") released a
Disclosure Update and Simplification Final Rule. The Final Rule amends
Regulation S-X disclosures requirements to conform them to U.S. Generally
Accepted Accounting Principles ("U.S. GAAP") for investment companies. The
Trust's financial statements were prepared in compliance with the new
amendments to Regulation S-X.

The Trust is an investment company and follows investment company accounting
and reporting guidance under U.S. GAAP. U.S. GAAP requires 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.

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

              Pioneer Diversified High Income Trust | Annual Report | 4/30/19 53



      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 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 into 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.

54 Pioneer Diversified High Income Trust | Annual Report | 4/30/19



      Options 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.

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

      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.

      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 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.

              Pioneer Diversified High Income Trust | Annual Report | 4/30/19 55



      At April 30, 2019, 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 6.12% of net assets. The value of these fair valued
      securities was $8,252,557.

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 the accrual basis. Dividend and interest income are reported
      net of unrecoverable foreign taxes withheld at the applicable country
      rates and net of income accrued on defaulted securities.

      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.

      Principal amounts of mortgage-backed securities are adjusted for monthly
      paydowns. Premiums and discounts related to certain mortgage-backed
      securities are amortized or accreted in proportion to the monthly
      paydowns. All discounts/premiums on purchase prices of debt securities are
      accreted/amortized for financial reporting purposes over the life of the
      respective securities, and such accretion/amortization is included in
      interest income.

      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, disposition of foreign currencies and the
      difference between the amount of income accrued and the U.S. dollars
      actually received. Further, the effects of changes in foreign currency
      exchange rates on investments are not segregated 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.

56 Pioneer Diversified High Income Trust | Annual Report | 4/30/19



D.    Federal Income Taxes

      It is the Trust's policy to comply with the requirements of the Internal
      Revenue Code applicable to regulated investment companies and to
      distribute all of its 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, 2019, the Trust did not accrue any
      interest or penalties with respect to uncertain tax positions, which, if
      applicable, would be recorded as an income tax expense 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 over distributions for
      financial statement purposes resulting from differences in the recognition
      or classification of income or distributions for financial statement and
      tax purposes. Capital accounts within the financial statements are
      adjusted for permanent book/tax differences to reflect tax character, but
      are not adjusted for temporary differences.

      At April 30, 2019, the Trust reclassified $1,249,417 to decrease
      distributable earnings (loss) and $1,249,417 to decrease paid-in capital
      to reflect permanent book/tax differences. These adjustments have no
      impact on net assets or the results of operations.

      At April 30, 2019, the Trust was permitted to carry forward indefinitely
      $3,095,755 of short-term losses and $32,091,344 of long-term losses under
      the Regulated Investment Company Modernization Act of 2010 without
      limitation. Capital loss not utilized and expired in 2019 amounts to
      $1,249,417.

      The tax character of distributions paid during the year ended April 30,
      2019 and April 30, 2018, were as follows:



      --------------------------------------------------------------------------
                                                       2019                2018
      --------------------------------------------------------------------------
                                                              
      Distributions paid from:
      Ordinary income                             $9,499,381        $10,499,315
      --------------------------------------------------------------------------
          Total                                   $9,499,381        $10,499,315
      ==========================================================================


              Pioneer Diversified High Income Trust | Annual Report | 4/30/19 57



      The following shows the components of distributable earnings (losses) on a
      federal income tax basis at April 30, 2019:



      --------------------------------------------------------------------------
                                                                           2019
      --------------------------------------------------------------------------
                                                                
      Distributable earnings:
      Undistributed ordinary income                                $    337,844
      Capital loss carryforward                                     (35,187,099)
      Other book/tax temporary differences                           (1,005,178)
      Unrealized depreciation                                           (92,922)
      --------------------------------------------------------------------------
          Total                                                    $(35,947,355)
      ==========================================================================


      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.

E.    Risks

      At times, the Trust's investments may represent industries or industry
      sectors that are interrelated or have common risks, making the Trust more
      susceptible to any economic, political, or regulatory developments or
      other risks affecting those industries and sectors. The Trust's
      investments in foreign markets and countries with limited developing
      markets may subject the Trust to a greater degree of risk than investments
      in a developed market. These risks include disruptive political or
      economic conditions and the imposition of adverse governmental laws or
      currency exchange restrictions.

      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. A general rise in
      interest rates could adversely affect the price and liquidity of fixed
      income securities.

      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

58 Pioneer Diversified High Income Trust | Annual Report | 4/30/19



      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 a significant amount of its total assets in illiquid
      securities. Illiquid securities are securities that the Trust reasonably
      expects cannot be sold or disposed of in the current market in seven
      calendar days or less without the sale or disposition significantly
      changing the market value of the 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, 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 Trust nor
      Amundi Pioneer exercises control. Each of

              Pioneer Diversified High Income Trust | Annual Report | 4/30/19 59



      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 net asset value, 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
      cost. 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.

F.    Insurance-Linked Securities ("ILS")

      The Trust invests in ILS. The Trust could lose a portion or all of the
      principal it has invested in an ILS, and the right to additional interest
      or dividend payments with respect to the security, upon the occurrence of
      one or more trigger events, as defined within the terms of an
      insurance-linked security. Trigger events, generally, are hurricanes,
      earthquakes, or other natural events of a specific size or magnitude that
      occur in a designated geographic region during a specified time period,
      and/or that involve losses or other metrics that exceed a specific amount.
      There is no way to accurately predict whether a trigger event will occur
      and, accordingly, ILS carry significant risk. The Trust is entitled to
      receive principal, and interest and/or dividend payments so long as no
      trigger event occurs of the description and magnitude specified by the
      instrument. In addition to the specified trigger events, ILS 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 event-linked bonds. ILS also
      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.

      Where the ILS 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

60 Pioneer Diversified High Income Trust | Annual Report | 4/30/19



      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.    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 sub-custodian 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 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.

      For the year ended April 30, 2019, the Trust had no open repurchase
      agreements.

H.    Purchased Options

      The Trust may purchase put and call options to seek to 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 Statement of
      Operations. 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 call and put options which have

              Pioneer Diversified High Income Trust | Annual Report | 4/30/19 61



      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 options is limited to the
      premium originally paid.

      The average market value of purchased options contracts open during the
      year ended April 30, 2019 was $86,508. Open purchased options at April 30,
      2019, are listed in the Trust's Schedule of Investments.

I.    Option Writing

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

      The average market value of written options for the year ended April 30,
      2019 was $(17,423). Open written options contracts at April 30, 2019, are
      listed in the Trust's Schedule of Investments.

J.    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

62 Pioneer Diversified High Income Trust | Annual Report | 4/30/19



      these contracts from the potential inability of counterparties to meet the
      terms of the contract and from unanticipated movements in the value of
      foreign currencies relative to the U.S. dollar (see Note 5).

      At April 30, 2019, the Trust had entered into various forward foreign
      currency contracts that obligated 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 market value of forward foreign currency contracts open during
      the year ended April 30, 2019 was $(2,588,019). Open forward foreign
      currency contracts outstanding at April 30, 2019, are listed in the
      Schedule of Investments.

K.    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 or 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 within the "Swap contracts, at value" line item 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

              Pioneer Diversified High Income Trust | Annual Report | 4/30/19 63



      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.

      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.
      In addition, obligations under sell protection credit default swaps may be
      partially offset by net amounts received from settlement of buy protection
      credit default swaps entered into by the Trust for the same reference
      obligation with the same counterparty.

      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 contract 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 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 a broker as collateral at April 30, 2019, if any, is
      recorded as "Swaps collateral" on the Statement of Assets and Liabilities.

      The average market value of credit default swap contracts open during the
      year ended April 30, 2019 was $5,260. Open credit default swap contracts
      at April 30, 2019, are listed in the Schedule of Investments.

L.    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

64 Pioneer Diversified High Income Trust | Annual Report | 4/30/19



      and may be terminated or resumed at any time without penalty by notifying
      American Stock Transfer & Trust Company, the agent for shareowners in
      administering the Plan (the "Plan Agent"), in writing prior to any
      dividend record date; otherwise such termination or resumption will be
      effective with respect to any subsequently declared dividend or other
      distribution.

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

              Pioneer Diversified High Income Trust | Annual Report | 4/30/19 65



securities), (ii) the issuance of preferred stock or other similar preference
securities, and/or (iii) any other means. For the year ended April 30, 2019,
net management fee was 0.85% of the Trust's average daily managed assets, which
was equivalent to 1.24% of the Trust's average daily net assets.

In addition, under the management and administration agreements, certain other
services and costs, including accounting, regulatory reporting and insurance
premiums, are paid by the Trust as administrative reimbursements. Included in
"Due to affiliates" reflected on the Statement of Assets and Liabilities is
$21,996 in management fees, administrative costs and certain other
reimbursements payable to the Adviser at April 30, 2019.

3. Transfer Agent

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 phone calls.

4. Master Netting Agreement

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 Over the Counter ("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.

66 Pioneer Diversified High Income Trust | Annual Report | 4/30/19



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 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 been offset on the Statement of Assets and
Liabilities. The following charts show gross assets and liabilities of the
Trust as of April 30, 2019.

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.

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,

8. Credit Agreement

Effective January 27, 2017, the Trust extended the maturity of its existing
Revolving Credit Facility (the "Credit Agreement") with the Bank of Nova Scotia
to January 27, 2020. There is a $70,000,000 borrowing limit.

At April 30, 2019, the Trust had a borrowing outstanding under the credit
agreement totaling $61,000,000. The interest rate charged at April 30, 2019 was
2.49%. During the year ended April 30, 2019, the average daily balance was
$62,805,405 at an average interest rate of 3.17%. Interest expense of
$2,017,593 in connection with the credit agreement is included on the Statement
of Operations.

The Trust is required to maintain 300% asset coverage with respect to amounts
outstanding under the credit agreement. Asset coverage is calculated by
subtracting the Trust's total liabilities not including any bank loans and
senior securities, from the Trust's total assets and dividing such amount by
the principal amount of the 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, 2019, 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 statement of changes in net assets and financial
highlights for the year ended April 30, 2018 (collectively referred to as the
"financial statements"). 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 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, 2019, the
results of its operations, the changes in its net assets, and the financial
highlights for the year ended, and the statement of changes in net assets and
the financial highlights for the year ended April 30, 2018, 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 Fund'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 | 4/30/19 71



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, 2019, by correspondence with the custodian and brokers.
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.

We have served as the Trust's auditor since 2017.

 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
to Rule 210.2-01(c)(7)(ii).

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

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

  pre-approved service subcategories set forth above must be specifically
  approved by the Audit Committee.

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

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

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.

paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is
compatible with maintaining the principal accountant's
independence.

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

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.

                             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.

ADDITIONAL INFORMATION ABOUT THE PORTFOLIO MANAGERS

OTHER ACCOUNTS MANAGED BY THE PORTFOLIO MANAGERS
The table below indicates, for the portfolio managers of the fund, information
about the accounts other than the fund over which the portfolio manager has
day-to-day investment responsibility. All information on the number of accounts
and total assets in the table is as of April 30, 2019. For purposes of the

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


                                       0


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 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
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
coverage for the preferred shares.

under the Exchange Act (17 CFR 240.13a-15(b) or 240.15d-15(b)).

The registrant's principal executive officer
