President's Letter

Dear Shareowner,

Global financial markets began 2016 on shaky footing, delivering the kind of
volatility that challenged investors in 2015. US equities fell by 10% through
the first six weeks of the year, only to recover the losses by the end of the
first quarter. Fixed-income markets were also acutely affected, with concerns
about falling oil prices and a weak global economy leading to a sell-off in
credit-sensitive sectors, especially high-yield bonds, as investors fled to the
perceived safety of government bonds. Like equities, credit markets recovered
much of their lost ground by the end of the first quarter.

Midway through the first quarter, market sentiment shifted, as expectations grew
that major central banks would extend their accommodative monetary policies in
the hopes of driving economic growth. The US Federal Reserve (the Fed) backed
off plans to raise interest rates four times in 2016, and the European Central
Bank announced a more comprehensive asset-purchasing program in the hopes of
encouraging lending, and boosting both inflation and economic growth. The Bank
of Japan also followed a monetary easing path, announcing negative interest
rates in January.

As 2016 moves along, we continue to see central bank policies as generally
supportive of the US economy - for which we maintain an expectation of modest
growth this year - against an overall global economic backdrop that remains
unsettled and points towards generally lower growth. Economies around the world
in both developed and emerging markets are experiencing deep structural changes.
Current challenges include incomplete debt deleveraging in both emerging and
developed markets, where debt levels continue to grow, the transition of many
emerging markets economies from export/investment-driven models to more domestic
demand-driven models, and aging populations, which are reducing productivity and
limiting economic growth potential (primarily in the developed markets but also
in emerging markets such as China). Geopolitical instability on many fronts, the
rising risk of policy mistakes, and market liquidity issues combine to increase
the possibility of sharp swings in asset values. Meanwhile, in the US, as always
in a presidential election year, the political rhetoric of 2016 has the
potential to impact domestic sectors such as health care.

Throughout Pioneer's history, we have believed in the importance of active
management. During periods of market volatility, we view the value of active
management as even more compelling. Our experienced and tenured investment teams
focus on identifying value across global markets using proprietary research,
careful risk management, and a long-term perspective. We believe our shareowners
can benefit from the experience and tenure of our investment teams as well as
the insights generated from our extensive research process.

2 Pioneer Diversified High Income Trust | Annual Report | 4/30/16


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

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

Sincerely,

/s/ Lisa M. Jones

Portfolio Management Discussion | 4/30/16

Worries about slowing global economic trends as well as weakening prices for oil
and other commodities created a difficult environment for the more credit-
sensitive sectors in the bond markets during most of the 12-month period ended
April 30, 2016. However, signs of some economic progress on the domestic front
led to a recovery in the credit-sensitive sectors over the final 10 weeks of the
period. In the following interview, Andrew Feltus, Charles Melchreit, Jonathan
Sharkey and Chin Liu discuss the factors that affected the performance of
Pioneer Diversified High Income Trust during the 12-month period. Mr. Feltus,
Director of High Yield and Bank Loans, a senior vice president and a portfolio
manager at Pioneer; Mr. Melchreit, Director of Investment-Grade Management, a
senior vice president and a portfolio manager at Pioneer; Mr. Sharkey, a senior
vice president and a portfolio manager at Pioneer; and Mr. Liu, a vice president
and a portfolio manager at Pioneer, are responsible for the day-to-day
management of the Trust. Note: Mr. Liu became a portfolio manager on the Trust
in September 2015.

Q    How did the Trust perform during the 12-month period ended April 30, 2016?

A    Pioneer Diversified High Income Trust returned -0.29% at net asset value
     and -1.26% at market price during the 12-month period ended April 30, 2016.
     During the same 12-month period, the Trust's custom benchmark returned
     0.69%. The custom benchmark is based on equal weights of the Bank of
     America Merrill Lynch (BofA ML) Global High Yield and Emerging Markets Plus
     (GHY and EMP) Index, which returned 1.50% at net asset value during the
     12-month period, and the Credit Suisse (CS) Leveraged Loan Index, which
     returned -0.13%. Unlike the Trust, the custom benchmark does not use
     leverage. While the use of leverage increases investment opportunity, it
     also increases investment risk.

     During the same 12-month period, the average return (at market price) of
     the 31 closed end funds in Lipper's High Yield Closed End Funds Category
     (which may or may not be leveraged) was -3.71%, and the average return (at
     market price) of the 22 closed end funds in Lipper's Loan Participation
     Closed End Funds Category (which may or may not be leveraged) was -3.82%.

     The shares of the Trust were selling at a 6.2% discount to net asset value
     at the end of the period on April 30, 2016.

     On April 30, 2016, the 30-day SEC yield on the Trust's shares was 9.03%*.

*    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 fixed-income
     markets during the 12-month period ended April 30, 2016?

A    The performance of higher-yielding, credit-sensitive bonds was
     disappointing for most of the Trust's fiscal year, although such securities
     recovered, somewhat, over the final weeks of the period as investors grew
     more hopeful about global economic conditions.

     During the early months of the 12-month period, a confluence of factors
     combined to dampen investors' optimism about the health of the world
     economy. Among the concerns vexing the markets were weakening prices for
     oil and other basic commodities, evidence of slowing economic growth in
     China, and a resurgent debt crisis in Greece that had the potential to
     threaten the wider European economy. The high-yield bond sectors strongly
     felt the effects of the market turmoil during that timeframe, with US
     high-yield corporate bonds and emerging markets debt, in particular,
     struggling due to the fallout from declining prices of oil, metals, and
     basic commodities.

     Meanwhile, although major central banks such as the European Central Bank
     (ECB) and the Bank of Japan adopted more accommodative monetary policies,
     the influential US Federal Reserve System (the Fed) appeared to signal its
     intent to become less accommodative and to start raising short-term
     interest rates in the United States as early as September 2015. The Fed,
     though, ended up delaying its anticipated rate hike and kept things
     unchanged in September, while advising the financial markets that it would
     look closely at a wide range of economic and market trends before
     tightening monetary policy. By the time Fed did raise rates by 0.25% in
     December 2015, market participants had already become more comfortable with
     its interest-rate posture.

     The downward move in high-yield and emerging markets bond prices finally
     appeared to bottom in February 2016, and the asset classes regained some of
     the ground they had lost earlier in the period. Several factors contributed
     to the bounce-back in the credit-sensitive sectors, including the Fed's
     cautious policy regarding interest rates, additional monetary easing from
     the ECB, the willingness of the Chinese government to adopt more
     aggressive, pro-growth policies, and a long-awaited rally in global oil and
     commodities prices. Securities that are highly sensitive to commodity
     prices, including energy industry and mining bonds, were the hardest hit
     during the market downturn early in the period, but they recovered sharply
     over the latter months as commodity prices rose and investors gravitated
     toward the very attractive valuations of those assets relative to their
     risks.

               Pioneer Diversified High Income Trust | Annual Report | 4/30/16 5


     In other areas of the market, floating-rate bank loans experienced modest
     losses, on a total return basis, during the full 12-month period, while the
     performance of insurance-linked securities (ILS) essentially was flat over
     the Trust's fiscal year.

Q    How did you manage the Trust's portfolio in that environment during the
     12-month period ended April 30, 2016?

A    During the period, we kept the Trust's portfolio well diversified** among
     the four main asset classes in which we typically invest: corporate bonds,
     emerging markets debt, floating-rate bank loans, and ILS. Fixed-rate
     investments, principally high-yield corporates and emerging markets debt,
     accounted for about 53% of the Trust's total investment portfolio as of
     period end, with the remaining 47% of the Trust's total investment
     portfolio allocated to floating-rate securities, mainly bank loans and ILS.

     With regard to specific asset classes, nearly 66% of the Trust's total
     investment portfolio was held in corporate bonds and notes as of April 30,
     2016, while senior secured bank loans, at 22% of the Trust's total
     investment portfolio, represented the portfolio's second-largest asset
     allocation. Within the allocation to corporate bonds and notes was a 19%
     position in insurance-linked securities, which included quota-share
     instruments and event-linked securities.

     Finally, we kept the duration of the Trust's portfolio on the short side
     (roughly 2.5 years) in anticipation that interest rates will eventually
     start to rise. (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    What were the primary reasons for the Trust's underperformance of its
     customized benchmark during the 12-month period ended April 30, 2016?

A    The main reason for the Trust's underperformance of its benchmark during
     the period was the use of leverage, or borrowed funds. While the
     investments in the Trust's portfolio generated close to a flat return over
     the 12-month period, the interest cost of the leverage reduced the Trust's
     total return. In addition, the portfolio's moderate allocation to
     high-yield energy bonds was another drag on the Trust's benchmark-relative
     returns during a period in which energy issues, especially lower-rated
     debt, performed poorly. Individual portfolio holdings in energy that hurt
     the Trust's benchmark-relative performance during the period included bonds
     issued by Penn Virginia, an oil and gas company; refiner MidStates Oil
     Refining; Noble Energy, an oil and gas drilling firm; and Williams
     Companies, a pipeline enterprise. The bonds of Noble Energy and

     Williams were investment-grade securities when we added them to the Trust's
     portfolio, but each suffered downgrades to high-yield status during the
     12-month period.

     Other detractors from the Trust's benchmark-relative returns during the
     period included positions in securities of European banking institutions,
     which struggled for two primary reasons. First, investors were worried that
     European banks might begin issuing a large supply of new, subordinated
     debt; and second, the forthcoming "Brexit" referendum in June, when
     citizens of the United Kingdom will decide whether to leave the European
     Economic Community, created much uncertainty and negatively affected the
     performance of the portfolio's European bank-related holdings.

Q    Which of your strategies or individual investments made positive
     contributions to the Trust's benchmark-relative returns during the 12-month
     period ended April 30, 2016?

A    The Trust's overall allocation to ILS proved to have the most significant
     positive influence on benchmark-relative performance during the period, as
     the property-and-casualty industry experienced relatively few significant
     losses from natural events such as hurricanes and earthquakes. The
     exception to the general "low claims" trend within ILS was the portfolio's
     investment in a MultiCat Mexico bond, a catastrophe bond sponsored by
     SwissRe. The bond suffered a 50% loss of principal from the landfall of
     Hurricane Patricia on Mexico's West Coast in October 2015.

     Investments in floating-rate bank loans also contributed positively to the
     Trust's benchmark-relative performance during the period, even though bank
     loans, in general, were relatively flat over the full 12 months due to
     technical market issues. A decline in the issuance of collateralized loan
     obligations (CLOs), which are major investors in bank loans, was the most
     notable of those technical issues in the bank-loan market over the period.

Q    How did the level of leverage in the Trust change over the 12-month period
     ended April 30, 2016?

A    The Trust employs leverage through a credit agreement (See Note 9 to the
     Financial Statements).

     At the end of the 12-month period on April 30, 2016, 29.1% of the Trust's
     total managed assets were financed by leverage (or borrowed funds),
     compared with 29.5% of the Trust's total managed assets financed by
     leverage at the start of the period on May 1, 2015. During the 12-month
     period, the Trust reduced borrowing under the revolving credit facility by
     a total of $7 million to $57 million as of April 30, 2016. Due to the
     overall decline in prices of high yield securities during the period, a
     reduction in the overall borrowing on the credit line was necessary in
     order to maintain the

               Pioneer Diversified High Income Trust | Annual Report | 4/30/16 7


     asset coverage requirements specified by the credit agreement. The
     percentage of the Trust's managed assets financed by leverage decreased
     during the period due to the reduction of borrowings and a decrease in the
     values of securities in which the Trust had invested.

Q    Did the Trust have any investments in derivative securities during the
     12-month period ended April 30, 2016? If so, did those investments have any
     effect on the Trust's performance?

A    During the period, the Trust did invest in some currency forward
     transactions in an attempt to hedge the effects of currency fluctuations on
     the value of the portfolio's investments in securities denominated in
     foreign currencies. The exposure did not have a material impact on the
     Trust's benchmark-relative results.

Q    What were the major factors affecting the Trust's distribution during the
     12-month period ended April 30, 2016?

A    The Trust's distribution was lowered in February 2016 because of a reduced
     amount of current income realized by the portfolio's investments. Over the
     full 12 months, in a low-interest-rate environment, the rates available on
     newer bond investments tended to be lower than the rates offered by older
     investments that had either reached maturity or been called away by their
     issuers.

Q    What is your investment outlook?

A    We believe the US economy should be able to grow at a moderate pace of 2.0%
     to 2.5% in 2016, despite getting off to a slow start in the first quarter,
     when gross domestic product (GDP) struggled to reach 1%. While poor sales
     figures and a slowdown in capital spending - both of which are tied to
     weakness in the energy markets - played a role in the first quarter's
     disappointing GDP figures, we still see persuasive evidence that the
     domestic economy is strengthening, as employment growth has been solid
     overall and household formation and new-home construction figures have been
     encouraging.

     While we foresee more growth on the domestic scene, global economic trends
     remain mixed. The recovery in Europe is proceeding at a slow pace, and we
     are concerned about the threatened exit of Britain from the European
     Economic Community, which we mentioned earlier. Meanwhile, the Chinese
     economy continues to be a major concern, particularly amid speculation
     about the excessive use of leverage. However, we are becoming more
     encouraged about growth prospects in selected emerging markets, especially
     if oil and other commodity prices did in fact bottom out earlier this year.

8 Pioneer Diversified High Income Trust | Annual Report | 4/30/16


     If, as we expect, the domestic economy shows continued improvement, we
     think a cautious Fed may further tighten monetary policy, perhaps raising
     short-term interest rates once or twice more in 2016. Therefore, we intend
     to maintain the Trust's short-duration stance.

     We believe a slow-growth environment should be good for the credit-
     sensitive markets. Corporate balance sheets continue to look solid and
     borrowing costs are not burdensome. Moreover, we do not see any noticeable
     signs of increases in debt, or leverage, in the economy, either by
     corporations or individual households. When it comes to investing in
     corporate bonds, we feel that security selection will be important,
     especially as we see some corporations taking shareholder-friendly actions,
     such as initiating mergers and increasing dividends. While high-yield
     corporate bond prices are not as compelling as they were in February of
     this year, prior to the market rally, they remain attractive. Yield
     spreads, which measure the differences between the yields of high-yield and
     high-quality bonds (typically Treasuries) with similar maturities, remain
     wider than long-term averages, and most sectors within high yield (other
     than energy, and metals and mining) are seeing improved performance. In
     addition, prices remain low relative to current high-yield default rates.

     Overall, we do not anticipate a robust rally in high-yield bonds, but we do
     see opportunities for continued performance improvement.

Please refer to the Schedule of Investments on pages 14-45 for a full listing of
Trust securities.

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

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

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

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

               Pioneer Diversified High Income Trust | Annual Report | 4/30/16 9


Interest rates in the U.S. recently have been historically low, so the Trust
faces a heightened risk that interest rates may rise. A general rise in interest
rates may cause investors to move out of fixed income securities on a large
scale, which could adversely affect the price and liquidity of fixed income
securities.

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

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

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

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

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

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

These risks may increase share price volatility.

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

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

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

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

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

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

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

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

1. Organization and Significant Accounting Policies

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

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

The following is a summary of significant accounting policies followed by the
Trust in the preparation of its financial statements:

A.   Security Valuation

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

     Fixed income securities are valued by using prices supplied by independent
     pricing services, which consider such factors as market prices, market
     events, quotations from one or more brokers, Treasury spreads, yields,
     maturities and ratings, or may use a pricing matrix or other fair value
     methods or techniques to provide an estimated value of the security or
     instrument. A pricing matrix is a means of valuing a debt security on the
     basis of current market prices for other debt securities, historical
     trading patterns in the market for fixed income securities and/or other
     factors. Valuations may be supplemented by dealers and other sources, as
     required. 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.

     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

52 Pioneer Diversified High Income Trust | Annual Report | 4/30/16


     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.

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

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

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

              Pioneer Diversified High Income Trust | Annual Report | 4/30/16 53


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

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

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

     At April 30, 2016, eleven securities were valued using fair value methods
     (in addition to securities valued using prices supplied by independent
     pricing services or broker-dealers) representing 4.7% of net assets. The
     value of these fair valued securities are $6,526,080.

B.   Investment Income and Transactions

     Dividend income is recorded on the ex-dividend date, except that certain
     dividends from foreign securities where the ex-dividend date may have
     passed are recorded as soon as the Trust becomes aware of the ex-dividend
     date in the exercise of reasonable diligence. Interest income, including
     interest on income bearing cash accounts, is recorded on an accrual basis,
     net of unrecoverable foreign taxes withheld at the applicable country
     rates.

54 Pioneer Diversified High Income Trust | Annual Report | 4/30/16


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

     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 in the Statement of Operations from
     the effects of changes in the market price of those securities but are
     included with the net realized and unrealized gain or loss on investments.

D.   Forward Foreign Currency Contracts

     The Trust may enter into forward foreign currency contracts (contracts) for
     the purchase or sale of a specific foreign currency at a fixed price on a
     future date. All contracts are marked to market daily at the applicable
     exchange rates, and any resulting unrealized appreciation or depreciation
     are recorded in the Trust's financial statements. The Trust records
     realized gains and losses at the time a contract is offset by entry into a
     closing transaction or extinguished by delivery of the currency. Risks may
     arise upon entering into these contracts from the potential inability of
     counterparties to meet the terms of the contracts and from unanticipated
     movements in the value of foreign currencies relative to the U.S. dollar
     (see Note 4).

E.   Federal Income Taxes

     It is the Trust's policy to comply with the requirements of the Internal
     Revenue Code applicable to regulated investment companies and to distribute
     all of its net taxable income and net realized capital gains, if any, to
     its shareowners. Therefore, no federal income tax provision is required. As
     of April 30, 2016, the Trust did not accrue any interest or penalties with
     respect to uncertain tax positions, which if applicable, would be recorded
     as an

              Pioneer Diversified High Income Trust | Annual Report | 4/30/16 55


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

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

     At April 30, 2016, the Trust reclassified $231,745 to increase paid-in
     capital, $547,782 to increase distributions in excess of net investment
     income and $779,527 to decrease accumulated net realized loss on
     investments to reflect permanent book/tax differences. These adjustments
     have no impact on the net assets or results of operations.

     At April 30, 2016, the Trust was permitted to carry forward $1,827,578 of
     short-term capital losses and $17,140,030 of long-term capital losses
     without limitation. Additionally, at April 30, 2016, the Trust had a net
     capital loss carry forward of $23,611,429 of which the following amounts
     will expire between 2017 and 2019 if not utilized: $413,150 in 2017,
     $21,948,862 in 2018, and $1,249,417 in 2019. Since unlimited losses are
     required to be used first, loss carry forwards that are subject to
     expiration may be more likely to expire unused.

     The Trust has elected to defer $377,261 of short-term capital losses and
     $6,909,119 of long-term capital losses recognized between November 1, 2015
     and April 30, 2016 to its fiscal year ending April 30, 2017.

     The tax character of distributions paid to shareowners during the years
     ended April 30, 2016 and April 30, 2015 were as follows:



     ---------------------------------------------------------------------------
                                                           2016             2015

     Distributions paid from:
     Ordinary income                                $12,499,185      $15,241,784

     The following shows the components of distributable earnings (losses) on a
     federal income tax basis at April 30, 2016:

     Distributable earnings:

     Capital loss carryforward                                      (42,579,037)
     Late year loss deferrals                                        (7,286,380)
     Unrealized depreciation                                         (7,294,753)
     ---------------------------------------------------------------------------
          Total                                                    $(55,842,298)
     ===========================================================================


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

F.   Insurance Linked Securities (ILS)

     The Trust invests in event-linked bonds. Event-linked bonds are floating
     rate debt obligations for which the return of principal and the payment of
     interest are contingent on the non-occurrence of a pre-defined "trigger"
     event, such as a hurricane or an earthquake of a specific magnitude. The
     trigger event's magnitude may be based on losses to a company or industry,
     industry indexes or readings of scientific instruments, or may be based on
     specified actual losses. If a trigger event, as defined within the terms of
     an event-linked bond occurs, the Trust may lose a portion or all of its
     accrued interest and/or principal invested in such event-linked bond. The
     Trust is entitled to receive principal and interest payments so long as no
     trigger event occurs of the description and magnitude specified by the
     instrument. In addition to the specified trigger events, event-linked bonds
     may expose the Trust to other risks, including but not limited to issuer
     (credit) default, adverse regulatory or jurisdictional interpretations and
     adverse tax consequences.

     The Trust's investments in ILS may include special purpose vehicles
     ("SPVs") or similar instruments structured to comprise a portion of a
     reinsurer's catastrophe-oriented business, known as quota share instruments
     (sometimes referred to as reinsurance sidecars), or to provide reinsurance
     relating to specific risks to insurance or reinsurance companies through a
     collateralized instrument, known as collateralized reinsurance. Structured
     reinsurance investments also may include industry loss warranties ("ILWs").
     A traditional ILW takes the form of a bilateral reinsurance contract, but
     there are also products that take the form of derivatives, collateralized
     structures, or exchange traded instruments.

              Pioneer Diversified High Income Trust | Annual Report | 4/30/16 57


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

G.   Purchased Options

     The Trust may purchase put and call options to seek increase total return.
     Purchased call and put options entitle the Trust to buy and sell a
     specified number of shares or units of a particular security, currency or
     index at a specified price at a specific date or within a specific period
     of time. Upon the purchase of a call or put option, the premium paid by the
     Trust is included in the Statement of Assets and Liabilities as an
     investment. All premiums are marked-to-market daily, and any unrealized
     gains or losses are recorded in the Trust's financial statements. As the
     purchaser of an index option, the Trust has the right to receive a cash
     payment equal to any depreciation in the value of the index below the
     strike price of the option (in the case of a put) or equal to any
     appreciation in the value of the index over the strike price of the option
     (in the case of a call) as of the valuation date of the option. Premiums
     paid for purchased calls and put options which have expired are treated as
     realized losses on investments in the Statement of Operations. Upon the
     exercise or closing of a purchased put option, the premium is offset
     against the proceeds on the sale of the underlying security or financial
     instrument in order to determine the realized gain or loss on investments.
     Upon the exercise or closing of a purchased call option, the premium is
     added to the cost of the security or financial instrument. The risk
     associated with purchasing options is limited to the premium originally
     paid. The average value of purchased options open for the year ended April
     30, 2016 was $0. Purchased option contracts outstanding at period end are
     listed within the Schedule of Investments.

H.   Risks

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

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

     The Trust invests in below investment grade (high yield) debt securities,
     floating rate loans and event-linked bonds sometimes referred to as
     "catastrophe" bonds or "insurance-linked" bonds. The Trust may invest in
     securities and other obligations of any credit quality, including those
     that are rated below investment grade, or are unrated but are determined by
     the investment adviser to be of equivalent credit quality. Below investment
     grade securities are commonly referred to as "junk bonds" and are
     considered speculative with respect to the issuer's capacity to pay
     interest and repay principal. Below investment grade securities, including
     floating rate loans, involve greater risk of loss, are subject to greater
     price volatility, and are less liquid and more difficult to value,
     especially during periods of economic uncertainty or change, than higher
     rated debt securities. 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

              Pioneer Diversified High Income Trust | Annual Report | 4/30/16 59


     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.

     Interest rates in the U.S. recently have been historically low, so the
     Trust faces a heightened risk that interest rates may rise. A general rise
     in interest rates may cause investors to move out of fixed income
     securities on a large scale, which could adversely affect the price and
     liquidity of fixed income securities.

I.   Automatic Dividend Reinvestment Plan

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

     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

60 Pioneer Diversified High Income Trust | Annual Report | 4/30/16


     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

PIM, a wholly owned indirect subsidiary of UniCredit S.p.A. (UniCredit), manages
the Trust's portfolio. Management fees payable under the Trust's Advisory
Agreement with PIM are calculated daily at the annual rate of 0.85% of the
Trust's average daily managed assets. "Managed assets" means (a) the total
assets of the Trust, including any form of investment leverage, minus (b) all
accrued liabilities incurred in the normal course of operations, which shall not
include any liabilities or obligations attributable to investment leverage
obtained through (i) indebtedness of any type (including, without limitation,
borrowing through a credit facility or the issuance of debt securities), (ii)
the issuance of preferred stock or other similar preference securities, and/or
(iii) any other means. For the year ended April 30, 2016, the net management fee
was 0.85% of the Trust's average daily managed assets, which was equivalent to
1.22% of the Trust's average daily net assets.

In addition, under PIM's management and administration agreements, certain other
services and costs are paid by PIM and reimbursed by the Trust. At April 30,
2016, $216,622 was payable to PIM related to management costs, administrative
costs and certain other services is included in "Due to affiliates" and
"Administration fee" on the Statement of Assets and Liabilities.

3. Transfer Agent

Prior to November 2, 2015, Pioneer Investment Management Shareholder Services,
Inc. (PIMSS), a wholly owned indirect subsidiary of UniCredit, through a
sub-transfer agency agreement with American Stock Transfer & Trust Company
(AST), provided substantially all transfer agent and shareowner services related
to the Trust's shares at negotiated rates.

Effective November 2, 2015, 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

5. Assets and Liabilities Offsetting

The Trust has entered into an International Swaps and Derivatives Association,
Inc. Master Agreement ("ISDA Master Agreement") or similar agreement with
substantially all its derivative counterparties. An ISDA Master Agreement is a
bilateral agreement between the Trust and a counterparty that governs the
trading of certain OTC derivatives and typically contains, among other things,

62 Pioneer Diversified High Income Trust | Annual Report | 4/30/16


close-out and set-off provisions which apply upon the occurrence of event of a
default and/or 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 a specific ISDA counterparty is subject.

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

Financial instruments subject to an enforceable master netting agreement such as
an ISDA Master Agreement have not been offset on the Statement of Assets and
Liabilities. The following charts show gross assets and liabilities of the Trust
as of April 30, 2016:

6. Additional Disclosures about Derivative Instruments and Hedging Activities

The Trust's use of derivatives subjects it 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 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.

9. Credit Agreement

Effective January 29, 2016, the Trust extended the maturity of its existing
Revolving Credit Facility (the Credit Agreement) with the Bank of Scotia. There
is a $70 million borrowing limit.

At April 30, 2016, the Trust had a borrowing outstanding under the credit
agreement totaling $57,000,000. The interest rate charged at April 30, 2016 was
1.31%. During the year ended April 30, 2016, the average daily balance was
$61,918,256 at an average interest rate of 1.15%. With respect to the credit
agreement, interest expense of $712,815 is included in the Statement of

Report of Independent Registered Public Accounting Firm

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

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Pioneer Diversified High Income Trust (the
"Trust"), as of April 30, 2016, and the related statements of operations and
cash flows for the year then ended, and the statements of changes in net assets
and the financial highlights for each of the two years in the period then ended.
These financial statements and financial highlights are the responsibility of
the Trust's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits. The financial
highlights for the years ended April 30, 2014, 2013, and 2012 were audited by
other auditors. Those auditors expressed an unqualified opinion on those
financial highlights in their report dated June 25, 2014.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. The Trust
is not required to have, nor were we engaged to perform, an audit of its
internal control over financial reporting. Our audits included consideration of
internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Trust's internal control over
financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of April 30, 2016, by correspondence with the custodian,
brokers and agent banks; where replies were not received from brokers and agent
banks, we performed other auditing procedures. We believe that our audits
provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Pioneer Diversified High Income Trust as of April 30, 2016, and the results of
its operations and its cash flows for the year then ended and the changes in its
net assets and the financial highlights for each of the two years in the period
then ended, in conformity with accounting principles generally accepted in the
United States of America.

ADDITIONAL INFORMATION (unaudited)

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

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

PIM, the Trust's investment adviser, is currently an indirect, wholly owned
subsidiary of UniCredit. On November 11, 2015, UniCredit announced that it
signed a binding master agreement with Banco Santander and affiliates of Warburg
Pincus and General Atlantic (the "Private Equity Firms") with respect to Pioneer
Investments ("Pioneer") and Santander Asset Management ("SAM") (the
"Transaction").

The Transaction, as previously announced by UniCredit, will establish a holding
company, with the name Pioneer Investments, to be owned by UniCredit (50%) and
the Private Equity Firms (50% between them). The holding company will control
Pioneer's U.S. operations, including PIM. The holding company also will own
66.7% of Pioneer's and SAM's combined operations outside the U.S., while Banco
Santander will own directly the remaining 33.3% stake. The closing of the
Transaction is expected to happen in 2016, subject to certain regulatory and
other approvals.

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

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

                  SECTION I - POLICY PURPOSE AND APPLICABILITY

The Pioneer Funds recognize the importance of maintaining the independence of
their outside auditors. Maintaining independence is a shared responsibility
involving Pioneer Investment Management, Inc ("PIM"), the audit committee and
the independent auditors.

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

Approval of a service in accordance with this policy for a Fund shall also
constitute approval for any other Fund whose pre-approval is required pursuant
to Rule 210.2-01(c)(7)(ii).

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

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

                 not performed by the Audit
                 firm, the scope of the Audit
                 Services would likely
                 increase.  The Services are
                 typically well-defined and
                 governed by accounting
                 professional standards (AICPA,
                 SEC, etc.)

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

o Potential services will be classified into the four non-restricted service
  categories and the "Approval of Audit, Audit-Related, Tax and Other
  Services" Policy above will be applied. Any services outside the specific
  pre-approved service subcategories set forth above must be specifically
  approved by the Audit Committee.

o At least quarterly, the Audit Committee shall review a report summarizing the
  services by service category, including fees, provided by the Audit firm as
  set forth in the above policy.

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


    (2) Disclose the percentage of services described in each of paragraphs (b)
   through (d) of this Item that were approved by the audit committee pursuant
   to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

Non-Audit Services
Beginning with non-audit service contracts entered
into on or after May 6, 2003, the effective date of the
new SEC pre-approval rules, the Trust's audit
committee is required to pre-approve services to
affiliates defined by SEC rules to the extent that the
services are determined to have a direct impact on the
operations or financial reporting of the Trust.  For the
years ended April 30 2016 and 2015, there were no
services provided to an affiliate that required the
Trust's audit committee pre-approval.



(f) If greater than 50 percent, disclose the percentage of hours expended on the
principal accountants engagement to audit the registrant's financial statements
for the most recent fiscal year that were attributed to work performed by
persons other than the principal accountant's full-time, permanent employees.

N/A

(g) Disclose the aggregate non-audit fees billed by the registrants accountant
for services rendered to the registrant, and rendered to the registrants
investment adviser (not including any sub-adviser whose role is primarily
portfolio management and is subcontracted with or overseen by another investment
adviser), and any entity controlling, controlled by, or under common control
with the adviser that provides ongoing services to the registrant for each of
the last two fiscal years of the registrant.

The aggregate non-audit fees for the Trust were $9,904
payable to Deloitte & Touche LLP for the year ended
April 30, 2016 and $9,876 for the year ended April 30, 2015.



(h) Disclose whether the registrants audit committee of the board of trustees
has considered whether the provision of non-audit services that were rendered to
the registrants investment adviser (not including any subadviser whose role is
primarily portfolio management and is subcontracted with or overseen by another
investment adviser), and any entity controlling, controlled by, or under common
control with the investment adviser that provides ongoing services to the
registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of
Rule 2-01 of Regulation S-X is compatible with maintaining the principal
accountant's independence.

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

ITEM 5. AUDIT COMMITTEE OF LISTED REGISTRANTS

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

N/A

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

Included in Item 1


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

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

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

                            VERSION DATED July, 2004

                                    Overview

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

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

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

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

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

                                       1


                             Proxy Voting Procedures

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

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

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

                                       2


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

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

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

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

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

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

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

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

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

                                       3


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

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

   Share-Blocking

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

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

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

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

       o   Retains a record of the vote cast;

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

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

                                       4


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

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

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

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

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

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

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

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

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

                                       5


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

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

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

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

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

   We will generally support these and similar management proposals:

       o    Corporate name change.

       o    A change of corporate headquarters.

       o    Stock exchange listing.

       o    Establishment of time and place of annual meeting.

       o    Adjournment or postponement of annual meeting.

       o    Acceptance/approval of financial statements.

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

       o    Approval of minutes and other formalities.

                                       6


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

       o    Amendments to authorized signatories.

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

       o    Acceptance of labor agreements.

       o    Appointment of internal auditors.

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

Auditors
     We normally vote for proposals to:

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

       o    Restore shareholder rights to ratify the auditors.

     We will normally oppose proposals that require companies to:

       o    Seek bids from other auditors.

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

       o    Indemnify auditors.

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

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

                                       7


     General Board Issues
     Pioneer will vote for:

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

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

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

       o    Election of an honorary director.

     We will vote against:

       o    Minimum stock ownership by directors.

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

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

       o    Requirements to provide two candidates for each board seat.

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

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

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

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

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

     We will also vote against:

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

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

                                       8


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

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

       o    Contested election of directors.

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

       o    Mandatory retirement policies.

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

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

     Pioneer will vote for:

       o    Cumulative voting.

       o    Increase ability for shareholders to call special meetings.

       o    Increase ability for shareholders to act by written consent.

       o    Restrictions on the ability to make greenmail payments.

       o    Submitting rights plans to shareholder vote.

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

       o    Opting out of the following state takeover statutes:

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

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

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

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

                                       9


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

     o Fair price provisions.

     o Authorization of shareholder rights plans.

     o Labor protection provisions.

     o Mandatory classified boards.

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

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

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

       o    Proposals that allow shareholders to nominate directors.

     We will vote against:

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

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

       o    Classes of shares with unequal voting rights.

       o    Supermajority vote requirements.

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

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

       o    Extension of advance notice requirements for shareholder proposals.

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

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

                                       10


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

     Pioneer will vote for:

       o    Changes in par value.

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

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

       o    Bond issuance.

       o    Increases in "ordinary" preferred stock.

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

       o    Cancellation of company treasury shares.

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

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

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

     o Number of shares currently available for issuance;

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

     o Proposed use of the additional shares; and

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

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

       o    Proposals to submit private placements to shareholder vote.

       o    Other financing plans.

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

                                      11


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

     Pioneer will vote for:

       o    401(k) benefit plans.

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

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

     o Amendments to performance plans to conform with OBRA;

     o Caps on annual grants or amendments of administrative features;

     o Adding performance goals; and

     o Cash or cash-and-stock bonus plans.

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

       o    Require that option repricings be submitted to shareholders.

       o    Require the expensing of stock-option awards.

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

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

                                       12


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

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

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

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

            A = Shares reserved for plan/amendment,

            B = Shares available under continuing plans,

            C = Shares granted but unexercised and

            D = Shares outstanding.

       o    The plan must not:

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

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

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

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

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

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

       o    All other employee stock purchase plans.

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

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

                                       13


     We will vote against:

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

       o    Elimination of stock option plans.

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

       o    Limits on executive and director pay.

       o    Stock in lieu of cash compensation for directors.

     Corporate Governance
     Pioneer will vote for:

       o    Confidential Voting.

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

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

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

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

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

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

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

     We will vote against:

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

       o    Limitations on stock ownership or voting rights.

       o    Reduction in share ownership disclosure guidelines.

                                       14


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

       o    Mergers and acquisitions.

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

       o    Debt restructurings.

       o    Conversion of securities.

       o    Issuance of shares to facilitate a merger.

       o    Private placements, warrants, convertible debentures.

       o    Proposals requiring management to inform shareholders of merger
            opportunities.

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

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

     Pioneer will vote for:

       o    Establishment of new classes or series of shares.

       o    Establishment of a master-feeder structure.

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

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

       o    Approval of new or amended advisory contracts.

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

       o    Authorization for, or increase in, preferred shares.

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

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

                                       15


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

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

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

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

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

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

                                       16

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

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


                                       0


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

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

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

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

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


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


                                       1


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

o QUANTITATIVE INVESTMENT PERFORMANCE. The quantitative investment performance
  calculation is based on pre-tax investment performance of all of the
  accounts managed by the portfolio manager (which includes the fund and any
  other accounts managed by the portfolio manager) over a one-year period (20%
  weighting) and four-year period (80% weighting), measured for periods ending
  on December 31. The accounts, which include the fund, are ranked against a
  group of mutual funds with similar investment objectives and investment
  focus (60%) and a broad-based securities market index measuring the
  performance of the same type of securities in which the accounts invest
  (40%), which, in the case of the fund, is the Merrill Lynch Global High
  Yield and Emerging Markets Index and the CSFB Leveraged Loan Index. As a
  result of these two benchmarks, the performance of the portfolio manager for
  compensation purposes is measured against the criteria that are relevant to
  the portfolio manager's competitive universe.

o QUALITATIVE PERFORMANCE. The qualitative performance component with respect
  to all of the accounts managed by the portfolio manager includes objectives,
  such as effectiveness in the areas of teamwork, leadership, communications
  and marketing, that are mutually established and evaluated by each portfolio
  manager and management.

o PIONEER RESULTS AND BUSINESS LINE RESULTS. Pioneer's financial performance,
  as well as the investment performance of its investment management group,
  affect a portfolio manager's actual bonus by a leverage factor of plus or
  minus (+/-) a predetermined percentage.

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

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

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

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

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

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

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

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

ITEM 9. PURCHASES OF EQUITY SECURITIES BY CLOSED-END MANAGEMENT
INVESTMENT COMPANY AND AFFILIATED PURCHASERS.

(a) If the registrant is a closed-end management investment company,
in the following tabular format, provide the information specified in
paragraph (b) of this Item with respect to any purchase made by or on
behalf of the registrant or any affiliated purchaser, as defined in
Rule 10b-18(a)(3) under the Exchange Act (17 CFR 240.10b-18(a)(3)), of
shares or other units of any class of the registrant's equity securities
that is registered by the registrant pursuant to Section 12 of the
Exchange Act (15 U.S.C. 781).

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



ITEM 10. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

Describe any material changes to the procedures by which shareholders
may recommend nominees to the registrant's board of directors, where
those changes were implemented after the registrant last provided
disclosure in response to the requirements of Item 407(c)(2)(iv) of
Regulation S-R(17 CFR 229.407)(as required by Item 22(b)(15))
of Schedule 14A (17 CFR 240.14a-101), or this Item.


There have been no material changes to the procedures by which the
shareholders may recommend nominees to the registrant's board of
directors since the registrant last provided disclosure in response
to the requirements of Item 407(c)(2)(iv) of Regulation S-R of Schedule 14(A)
in its definitive proxy statement, or this item.


ITEM 11. CONTROLS AND PROCEDURES.

(a) Disclose the conclusions of the registrant's principal executive and
principal financials officers, or persons performing similar functions,
regarding the effectiveness of the registrant's disclosure
controls and procedures (as defined in Rule 30a-3(c) under the Act (17 CFR
270.30a-3(c))) as of a date within 90 days of the filing date of the report
that includes the disclosure required by this paragraph,
based on the evaluation of these controls and procedures required by Rule
30a-3(b) under the Act (17 CFR 270.30(a)-3(b) and Rules 13a-15(b) or 15d-15(b)
under the Exchange Act (17 CFR 240.13a-15(b) or 240.15d-15(b)).

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


(b) Disclose any change in the registrant's internal control over financial
reporting (as defined in Rule 30a-3(d) under the Act (17CFR 270.30a-3(d)) that
occured during the second fiscal quarter of the period covered by this report
that has materially affected, or is reasonably likely to materially affect,
the registrant's internal control over financial reporting.

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

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

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


ITEM 12. EXHIBITS.

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

(1) Any code of ethics, or amendment thereto, that is the subject of the
disclosure required by Item 2, to the extent that the registrant intends to
satisfy the Item 2 requirements through filing of an exhibit.



(2) A separate certification for each principal executive officer and principal
financial officer of the registrant as required by Rule 30a-2(a) under the Act
(17 CFR 270.30a-2(a)) , exactly as set forth below:

Filed herewith.
