President's Letter

Dear Shareowner,

A few months into 2014, we still expect U.S. economic growth for the year to be
in the 2.5% to 3% range, despite some weaker economic data releases during the
winter months driven in large part by harsh weather across much of the
continental U.S. While unemployment remains high, employment has been rising
steadily. Consumer incomes, savings, wealth, and debt-servicing capacity have
been solid buttresses for the recovering housing and auto industries. Industrial
activity is growing only moderately, but current corporate profits are generally
solid and balance sheets appear able to support needed capital spending and
dividend* payouts. A modestly improving European economy and continuing economic
improvement in Japan appear likely to result in improving global growth in 2014,
further supporting the U.S. economy. In addition, we feel that continuing slack
in labor markets and capacity utilization offer the potential for continuing
growth without bottlenecks and rising inflation.

After observing the strengthening economic trends, the Federal Reserve System
(the Fed) has begun scaling back its QE (quantitative easing) program, but
short-term interest rates remain near zero, and while Fed Chair Janet Yellen has
suggested that rates may be raised roughly six months after the QE program is
fully tapered, that would still place the potential rate hike sometime in 2015.

There are certainly risks and uncertainties still facing the global economy as
2014 moves along. The European economy, while improving, remains weak, the
Japanese economy faced a tax hike this spring, and a number of emerging market
countries are experiencing difficulties. There are also geopolitical worries
abroad, such as Russia's aggressive move against the Ukraine, and more potential
political fights at home, especially during a mid-term election year. While most
of the widely recognized risks we have outlined may already be "priced into" the
market, we believe investors should continue to expect market volatility.

At Pioneer, we have long advocated the benefits of staying diversified and
investing for the long term. And while diversification does not assure a profit
or protect against loss in a declining market, we believe there are still
opportunities for prudent investors to earn attractive returns. Our advice, as
always, is to work closely with a trusted financial advisor to discuss your
goals and work together to develop an investment strategy that meets your
individual needs, keeping in mind that there is no single best strategy that
works for every investor.

Portfolio Management Discussion | 4/30/14

Despite bouts of volatility, particularly in the late spring and summer of 2013,
most credit-sensitive sectors generated solid, positive returns over the
12-month period ended April 30, 2014. In the following interview, Andrew Feltus,
Charles Melchreit and Jonathan Sharkey discuss the factors that affected the
performance of Pioneer Diversified High Income Trust during the 12-month period.
Mr. Feltus, a senior vice president and portfolio manager at Pioneer, Mr.
Melchreit, a senior vice president and portfolio manager at Pioneer, and Mr.
Sharkey, a senior vice president and portfolio manager at Pioneer, all are
members of Pioneer's Fixed-Income Team and are responsible for the day-to-day
management of the Trust.

Q   How did the Trust perform during the 12-month period ended April 30, 2014?

A   Pioneer Diversified High Income Trust returned 8.47% at net asset value and
    7.12% at market price during the 12-month period ended April 30, 2014.
    During the same 12-month period, the Trust's custom benchmark returned 5.32%
    at net asset value. The custom benchmark is based on equal weightings of the
    Bank of America Merrill Lynch (BofA ML) Global High Yield and Emerging
    Markets Plus (GHY and EMP) Index, which returned 6.13% at net asset value
    during the 12-month period, and the Credit Suisse (CS) Leveraged Loan Index,
    which returned 4.50% at net asset value. 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 33 closed-end
    funds in Lipper's High Current Yield Closed End Funds category (which may or
    may not be leveraged) was 4.93%, and the average return (at market price) of
    the 20 closed-end funds in Lipper's Loan Participation Closed End Funds
    category (which may or may not be leveraged) was -4.20%.

    The shares of the Trust were selling at a 4.1% premium to net asset value at
    the end of the period on April 30, 2014.

    On April 30, 2014, the 30-day SEC yield on the Trust's shares was 7.03%*.

Q   How would you describe the investment environment for fixed-income assets
    during the 12-month period ended April 30, 2014?

A   The backdrop for investing in high-yield bonds and other credit-sensitive
    securities was challenging during the first part of the Trust's fiscal year,
    particularly during the spring and early summer of 2013. The most

*   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.

    immediate cause of volatility in the bond markets was investors' reaction in
    May 2013 to then-U.S. Federal Reserve System (Fed) Chair Ben Bernanke's
    suggestion that the Fed might begin tapering its quantitative easing (QE)
    bond-buying program, which had been a key part of the Fed's accommodative
    monetary policies that had helped to keep interest rates low and provided a
    measure of support to overall economic growth. The suggestion raised fears
    of rising interest rates, which became a self-fulfilling prophecy and led to
    a sell-off of the fixed-income markets in the second calendar quarter of
    2013. Investors also began to worry about the vitality of the domestic
    economic recovery as new-job creation continued to be weak and corporate
    profit gains appeared to slow. In that environment, fixed-income
    investments in general produced lackluster returns, with credit-sensitive
    securities particularly hard hit on worries about potentially slowing
    economic growth.

    At the same time, Mr. Bernanke's comments had a significant impact on
    emerging markets, causing a flight of capital out of those developing
    economies that were less financially liquid and most dependent on the flow
    of money from the United States. Emerging markets such as India, Indonesia
    and, to a lesser extent, the Philippines, were especially hurt by the
    outflows. However, even more liquid emerging markets, like Mexico, were
    affected. Commodity-producing emerging markets also felt the effects of
    slowing growth trends in China as that nation began transitioning to a more
    consumer-driven economy less dependent on giant infrastructure and building
    projects.

    Heading into the fall of 2013, the market for credit-sensitive securities
    recovered as more evidence accumulated that the U.S. economy was gathering
    strength. Improving employment and housing trends were some of the
    encouraging economic signs, and inflation, meanwhile, remained in check.
    Investors also began to anticipate that any monetary tightening by the Fed -
    based on follow-up statements made by Mr. Bernanke after his "tapering"
    comments in May 2013 - would be done gradually and in response to new
    evidence of economic strengthening. Moreover, the transition of leadership
    at the Fed in early 2014 from Mr. Bernanke to new Chair Janet Yellen
    appeared to signal confirmation of a gradual evolution of monetary policy
    rather than an abrupt change. The Fed ended up delaying its official
    announcement regarding the tapering of QE until December of 2013, and began
    reducing its monthly bond purchases in 2014, with the eventual goal being to
    fully conclude the QE program by the end of the current calendar year.

               Pioneer Diversified High Income Trust | Annual Report | 4/30/14 5


    Meanwhile, worries about the economic consequences of partisan political
    wrangling in Washington abated as a late-2013 bipartisan agreement
    establishing top-line Federal spending levels for the next two fiscal years
    seemed to, temporarily at least, put an end to the constant bickering
    between Democrats and Republicans over the nation's fiscal course, and that
    news also buoyed market sentiment. In addition, investors were encouraged
    that fiscal policy would be less of a factor holding back the economy's
    growth potential, as spending cuts at the Federal level ("sequestration")
    were slated to be eased as part of the bipartisan budget agreement. Finally,
    the threat that American military forces might be drawn into battle over
    control of Syria also declined over the second half of the Trust's fiscal
    year, although new worries emerged very late in the period over Russia's
    aggressive moves against the Ukraine.

    As the markets grew calmer during the second half of the 12-month period,
    high-yield and investment-grade corporate bonds as well as most other
    credit-sensitive securities tended to perform well, while U.S. Treasuries
    and government agency debt came under pressure when market interest rates
    for most maturities increased. Yield spreads (the differences in yields
    between credit-sensitive debt and Treasuries of similar maturity) tightened
    and the credit sectors outperformed Treasuries. Floating-rate securities,
    including bank loans and insurance-linked (catastrophe) securities sponsored
    by insurance companies, tended to hold up relatively well during the period
    as the prospect of higher future interest rates garnered additional investor
    interest. Bank loans, in particular, performed well during the summer of
    2013. The performance of insurance-linked securities, meanwhile, benefited
    from a relatively mild hurricane season in 2013.

Q   How did you position the Trust's portfolio during the 12-month period ended
    April 30, 2014, and how did the positioning affect the Trust's performance?

A   Consistent with our long-term investment strategy, we kept the Trust's
    portfolio well diversified** during the period, with an emphasis on the
    credit sectors, especially high-yield bonds. The positioning helped the
    Trust's performance significantly, as high-yield bonds in particular snapped
    back to outperform other similar asset classes late in 2013 and into 2014.
    Insurance-linked securities, as noted previously, also fared well, helped by
    both the benign storm season and an inflow of investor capital into the
    asset class. Floating-rate bank loans performed positively overall while
    adding stability to the Trust's portfolio during the highly volatile period
    in mid-2013, although those securities underperformed high-yield and

**  Diversification does not assure a profit nor prevent loss.

    insurance-linked securities over the full 12-month period. Emerging markets
    bonds - both sovereigns and corporates - recovered very well after problems
    early in the period and ended up producing positive performance over the
    full 12 months. Those securities, however, also lagged the returns produced
    by domestic high-yield corporates. The Trust's currency positioning exerted
    a slight drag on results, as part of the portfolio's exposure to emerging
    markets currencies was unhedged and was, therefore, negatively affected by
    declining performance of emerging markets currencies.

    At the end of the period, on April 30, 2014, U.S. high-yield corporate bonds
    represented the largest position in the Trust's total investment portfolio.
    Insurance-linked securities represented the next-highest allocation. Other
    significant allocations in the Trust's portfolio at period end included
    floating-rate bank loans, and emerging markets debt.

Q   Which individual investments had notable effects on the Trust's performance
    during the 12-month period ended April 30, 2014?

A   Securities that made significant positive contributions to the Trust's
    returns during the 12-month period included portfolio positions in a U.S.
    high-yield bond issued by Pegasus Solutions, an information technology
    company that operates an electronic reservations and processing system for
    the hotel and hospitality industry; and an insurance-linked security issued
    by Residential Re. Among the more disappointing holdings in the portfolio
    during the period were high-yield bonds issued by Codere, a Spanish casino
    company, and by NII Holdings, which operates a wireless telecommunication
    services company in Latin America.

Q   Did the use of derivatives affect the Trust's performance during the
    12-month period ended April 30, 2014?

A   We did use currency forward contracts to reduce the potential risks to the
    Trust's portfolio created by volatility in the relative values of different
    currencies. The tactic had a slight negative influence on the Trust's
    performance during the 12-month period.

Q   How did the level of leverage in the Trust change during the 12-month period
    ended April 30, 2014?

A   During the period, the value of securities held by the Trust decreased. As a
    result, the dollar amount of leverage employed by the Trust was reduced from
    $69 million to $67 million in order to meet asset coverage requirements for
    its borrowings (see Note 7). The percentage of the Trust's total managed
    assets financed by leverage at the end of the 12-month period (28.7%) was
    the same as at the beginning of the period.

               Pioneer Diversified High Income Trust | Annual Report | 4/30/14 7


Q   What is your investment outlook?

A   We retain a positive view on the economic growth outlook in general, and
    that should continue to support healthy corporate earnings as well as the
    performance of credit-sensitive securities, especially corporate high-yield
    bonds. In an expanding economy, the default rates for high-yield bonds
    should remain low by historical standards, which should support their
    prices. However, price appreciation has caused the yield advantages of high-
    yield bonds over other fixed-income assets to tighten, and so we think most
    of the future returns from this asset class are likely to derive from their
    higher yields rather than from any further significant price increases.

    It is significant to point out that the Trust retains a sizable allocation
    to floating-rate securities, notably insurance-linked securities and bank
    loans. We believe the floating-rate characteristics of such securities
    should help them to perform well if market interest rates rise sooner than
    expected, or if the Fed does in fact begin increasing short-term rates,
    which is a real possibility sometime in 2015.

    Looking ahead, we intend to keep the Trust's portfolio well diversified
    across the various fixed-income sectors in an attempt to take advantage of
    opportunities in different areas of the market, including in high-yield
    corporate bonds, emerging markets debt, insurance-linked securities and
    floating-rate bank loans.

    Please refer to the Schedule of Investments on pages 13-44 for a full
    listing of Trust securities.

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

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

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

    The Trust may invest a significant amount of its total assets in illiquid
    securities. Illiquid securities may be difficult to dispose of at a fair
    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.

    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.

    Past performance is no guarantee of future results, and there is no
    guarantee that market forecasts discussed will be realized.

    Any information in this shareowner report regarding market or economic
    trends or the factors influencing the Trust's historical or future
    performance are statements of opinion as of the date of this report. These
    statements should not be relied upon for any other purposes.

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.

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

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

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

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

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

Notes to Financial Statements | 4/30/14

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
year. Actual results could differ from those estimates.

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

A.  Security Valuation

    Security transactions are recorded as of trade date. Senior floating rate
    loan interests (senior loans) are valued in accordance with guidelines
    established by the Board of Trustees at the mean between the last available
    bid and asked prices from one or more brokers or dealers as obtained from
    Loan Pricing Corporation, an independent pricing service. If price
    information is not available from Loan Pricing Corporation or if the price
    information is deemed to be unreliable, price information will be obtained
    from an alternative loan interest pricing service. If no reliable price
    quotes are available from either the primary or alternative pricing service
    broker quotes will be solicited. Fixed-income securities with remaining
    maturities of more than sixty days are valued at prices supplied by
    independent pricing services, which consider such factors as market prices,
    market events, quotations from one or more brokers, Treasury spreads,
    yields, maturities and ratings. Valuations may be supplemented by dealers
    and other sources, as required. Equity securities that have traded on an
    exchange are valued at the last sale price on the principal exchange where
    they are traded. Equity securities that have not traded on the date of
    valuation or securities for which sale prices are not available, generally
    are valued using the mean between the last bid and

              Pioneer Diversified High Income Trust | Annual Report | 4/30/14 51


    asked prices. Short-term fixed income securities with remaining maturities
    of sixty days or less generally are valued at amortized cost. Shares of
    money market mutual funds are valued at such funds' net asset value.

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

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

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

    At April 30, 2014, two securities were valued using fair value methods (in
    addition to securities valued using prices supplied by independent pricing
    services or broker-dealers) representing 2.2% of net assets applicable to
    common shareowners. The value of these fair valued securities are
    $3,734,563.

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

    Interest 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.

52 Pioneer Diversified High Income Trust | Annual Report | 4/30/14


    Dividend income is recorded on the ex-dividend date, except that certain
    dividends from foreign securities where the ex-dividend date may have passed
    are recorded as soon as the Trust becomes aware of the ex-dividend data in
    the exercise of reasonable diligence.

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

B.  Foreign Currency Translation

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

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

C.  Forward Foreign Currency Contracts

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

D.  Federal Income Taxes

    It is the Trust's policy to comply with the requirements of the Internal
    Revenue Code applicable to regulated investment companies and to distribute
    all of its taxable income and net realized capital gains, if any, to its
    shareowners. Therefore, no federal income tax provision is required. As of
    April 30, 2014, the Trust did not accrue any interest or penalties with
    respect to uncertain tax positions, which if applicable, would be recorded
    as 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.

              Pioneer Diversified High Income Trust | Annual Report | 4/30/14 53


    The amount and character of income and capital gain distributions to
    shareowners are determined in accordance with federal income tax rules,
    which 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 purposes resulting from
    differences in the recognition or classification of income or distributions
    for financial statement and tax purposes. Capital accounts within the
    financial statements are adjusted for permanent book/tax differences to
    reflect tax character, but are not adjusted for temporary differences. At
    April 30, 2014, the Trust reclassified $56,925 to decrease Distributions in
    excess of net investment income, $56,926 to increase accumulated net
    realized loss on investments and foreign currency transactions and $1 to
    decrease Paid-in capital to reflect permanent book/tax differences. These
    adjustments have no impact on the net assets or results of operations.

    At April 30, 2014, the Trust was permitted to carry forward $4,901,516 of
    long term and $708,926 of short term losses without limitation.
    Additionally, at April 30, 2014, the Trust had a net capital loss carry
    forward of $23,843,173 of which the following amounts will expire between
    2016 and 2019 if not utilized: $231,744 in 2016, $413,150 in 2017,
    $21,948,862 in 2018, and $1,249,417 in 2019. Since unlimited losses are
    required to be used first, loss carry forwards that are subject to
    expiration may be more likely to expire unused.

    The Trust has elected to defer $1,642,624 of capital losses recognized
    between November 1, 2013 and April 30, 2014 to its fiscal year ending April
    30, 2015.

    The tax character of current year distributions payable to common and
    preferred shareowners will be determined at the end of the current taxable
    year. The tax character of distributions paid during the year ended April
    30, 2014 was as follows:



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

         Total                                                   $ (27,782,107)
    ============================================================================


    The difference between book-basis and tax-basis unrealized appreciation is
    primarily attributable to the tax deferral of losses on wash sales, 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 for premiums and discounts on fixed income securities
    and other temporary book/tax differences.

E.  Risks

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

    The Trust invests in below investment grade (high yield) debt securities,
    floating rate loans and event-linked bonds sometimes referred to as
    "catastrophe" bonds or "insurance-linked" bonds. The Trust may invest in
    securities and other obligations of any credit quality, including those that
    are rated below investment grade, or are unrated but are determined by the
    investment adviser to be of equivalent credit quality. Below investment
    grade securities are commonly referred to as "junk bonds" and are considered
    speculative with respect to the issuer's capacity to pay interest and repay
    principal. Below investment grade securities, including floating rate loans,
    involve greater risk of loss, are subject to greater price volatility, and
    are less liquid and more difficult to value, especially during periods of
    economic uncertainty or change, than higher rated debt securities. The trust
    may invest in securities of issuers that are in default or that are in
    bankruptcy. The value of collateral, if any, securing a floating rate loan
    can decline or may be insufficient to meet the issuer's obligations or may
    be difficult to liquidate. No

              Pioneer Diversified High Income Trust | Annual Report | 4/30/14 55


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

F.  Repurchase Agreements

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

G.  Automatic Dividend Reinvestment Plan

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

    If a shareowner's shares are held in the name of a brokerage firm, bank or
    other nominee, the shareowner can ask the firm or nominee to participate in
    the Plan on the shareowner's behalf. If the firm or nominee does not offer
    the

56 Pioneer Diversified High Income Trust | Annual Report | 4/30/14


    Plan, dividends will be paid in cash to the shareowner of record. A firm or
    nominee may reinvest a shareowner's cash dividends in common shares of the
    Trust on terms that differ from the terms of the Plan.

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

H.  Option Writing

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

              Pioneer Diversified High Income Trust | Annual Report | 4/30/14 57


    Trust has realized a gain or loss. The Trust as a writer of an option bears
    the market risk of an unfavorable change in the price of the security
    underlying the written option.

    The average value of option contracts open for the year ended April 30, 2014
    was $10,888. Written call and put option contracts outstanding at period end
    are listed at the end of the Trust's schedule of investments.

    The Trust held one written call option contract that was open at April 30,
    2014. If the call option was exercised at April 30, 2014, the maximum amount
    the Fund would have been required to pay was $4,052.

    Transactions in written call options for the year ended April 30, 2014 are
    summarized as follows:

    ============================================================================


I.  Purchased Options

    The Trust may purchase put and call options to seek increase total return.
    Purchased call and put options entitle the Trust to buy and sell a specified
    number of shares or units of a particular security, currency or index at a
    specified price at a specific date or within a specific period of time. Upon
    the purchase of a call or put option, the premium paid by the Trust is
    included in the Statement of Assets and Liabilities as an investment. All
    premiums are marked-to-market daily, and any unrealized gains or losses are
    recorded in the Trust's financial statements. As the purchaser of an index
    option, the Trust has the right to receive a cash payment equal to any
    depreciation in the value of the index below the strike price of the option
    (in the case of a put) or equal to any appreciation in the value of the
    index over the strike price of the option (in the case of a call) as of the
    valuation date of the option. Premiums paid for purchased calls and put
    options which have expired are treated as realized losses on investments in
    the Statement of Operations. Upon the exercise or closing of a purchased put
    option, the premium is offset against the proceeds on the sale of the
    underlying security or financial instrument in order to determine the
    realized gain or loss on investments. Upon the exercise or closing of a
    purchased call option, the premium is added to the cost of the security or
    financial instrument. The risk associated with purchasing options is limited
    to the premium originally paid. The average value of purchased options
    during the year ended April 30, 2014 was $7,953. Purchased option contracts
    outstanding at year end are listed at the end of the Trust's schedule of
    investments.

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, 2014, the net management fee
was 0.85% of the Trust's average daily managed assets, which was equivalent to
1.20% of the Trust's average daily net assets.

In addition, under PIM's management and administration agreements, certain other
services and costs are paid by PIM and reimbursed by the Trust. At April 30,
2014 $221,259 was payable to PIM related to management costs, administrative
costs and certain other services and is included in "Due to affiliates" and
"Administration fee payable" on the Statement of Assets and Liabilities.

3. Transfer Agents

Pioneer Investment Management Shareholder Services, Inc. (PIMSS), a wholly owned
indirect subsidiary of UniCredit, through a sub-transfer agency agreement with
American Stock Transfer & Trust Company, provides substantially all transfer
agent and shareowner services related to the Trust at negotiated rates. In
addition, the Trust reimburses PIMSS for out-of-pocket expenses incurred by
PIMSS related to shareowner communications activities such as proxy and
statement mailings and outgoing calls.

4. Expense Offset Arrangement

The Trust has entered into an arrangement with its custodian whereby credits
realized as a result of uninvested cash balances are used to reduce a portion of
the Trust's custodian expenses. For the year ended April 30, 2014, the Trust
expenses were not reduced under such arrangement.

5. Forward Foreign Currency Contracts

At April 30, 2014, the Trust had entered forward foreign currency contracts that
obligate the Trust to deliver or take delivery of currencies at specified future
maturity dates. Alternatively, prior to the settlement date of a forward foreign
currency contract, the Trust may close out such contract by entering into an
offsetting contract. The average value of contracts open during the year ended
April 30, 2014 was $9,066,309.

7. Loan Agreement

Effective January 31, 2014, the Trust extended the maturity of its existing
Revolving Credit Facility (the Credit Agreement) with the Bank of Nova Scotia;
the amount of the facility remains at $75 million.

At April 30, 2014, the Trust had a borrowing outstanding under the Credit
Agreement totaling $67,000,000. The interest rate charged at April 30, 2014 was
1.00%. During the year ended April 30, 2014, the average daily balance was
$67,816,667 at a weighted average interest rate of 1.06%. With respect to the
loan, interest expense of $743,785 is included in the Statement of Operations.

The Trust is required to maintain 300% asset coverage with respect to amounts
outstanding under the Credit Agreement. Asset coverage is calculated by
subtracting the Trust's total liabilities, not including any bank loans and
senior securities, from the Trust's total assets and dividing such amount by the
principal amount of the borrowings outstanding. As of the date indicated below,
the Trust's debt outstanding and asset coverage were as follows:

10. Subsequent Events

The Board of Trustees of the Trust declared on May 5, 2014 a monthly dividend
from undistributed net investment income of $0.16 per common share payable May
30, 2014, to shareowners of record on May 19, 2014.

Change in Independent Registered Public Accounting Firm

The Board of Trustees of the Trust, with the approval and recommendation of the
Audit Committee, appointed Deloitte & Touche LLP to serve as the Trust's
independent registered public accounting firm for the fiscal year ending April
30, 2015. Deloitte & Touche LLP replaces Ernst & Young LLP, which resigned as
the Trust's independent registered public accounting firm, effective upon
completion of the audit of the Trust's financial statements for the fiscal year
ended April 30, 2014.

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

Report of Independent Registered Public Accounting Firm

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

We have audited the accompanying statement of assets and liabilities of Pioneer
Diversified High Income Trust (the "Trust"), including the schedule of
investments, as of April 30, 2014, and the related statements of operations and
cash flows for the year then ended, the statements of changes in net assets for
each of the two years in the period then ended and the financial highlights for
each of the five 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.

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. We were
not engaged to perform an audit of the Trust's 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 and financial highlights, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall
financial statement presentation. Our procedures included confirmation of
securities owned as of April 30, 2014, by correspondence with the custodian and
brokers or by other appropriate auditing procedures where replies from brokers
were not received. 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 at April 30, 2014, the results of its
operations and cash flows for the year then ended, the changes in its net assets
for each of the two years in the period then ended, and the financial highlights
for each of the five years in the period then ended, in conformity with U.S.
generally accepted accounting principles.

                                                           /s/ Ernst & Young LLP

Approval of Investment Advisory Agreement

Pioneer Investment Management, Inc. (PIM) serves as the investment adviser to
Pioneer Diversified High Income Trust (the Trust) pursuant to an investment
advisory agreement between PIM and the Trust. In order for PIM to remain the
investment adviser of the Trust, the Trustees of the Trust must determine
annually whether to renew the investment advisory agreement for the Trust.

The contract review process began in March 2013 as the Trustees of the Trust
agreed on, among other things, an overall approach and timeline for the process.
In July 2013, the Trustees approved the format of the contract review materials
and submitted their formal request to PIM to furnish information necessary to
evaluate the terms of the investment advisory agreement. The contract review
materials were provided to the Trustees in July 2013 and September 2013. After
reviewing and discussing the materials, the Trustees submitted a request for
additional information to PIM, and materials were provided in response to this
request. Meetings of the Independent Trustees of the Trust were held in July,
September, and November, 2013 to review and discuss the contract review
materials. In addition, the Trustees took into account the information related
to the Trust provided to the Trustees at regularly scheduled meetings.

At a meeting held on November 12, 2013, based on their evaluation of the
information provided by PIM and third parties, the Trustees of the Trust,
including the Independent Trustees voting separately, unanimously approved the
renewal of the investment advisory agreement for another year. In considering
the renewal of the investment advisory agreement, the Trustees considered
various factors that they determined were relevant, including the factors
described below. In all quintile rankings referred to throughout this
disclosure, first quintile is most favorable to the Trust's shareowners. Thus,
highest relative performance would be first quintile and lowest relative
expenses would also be first quintile. The Trustees did not identify any single
factor as the controlling factor in determining to approve the renewal of the
agreement.

Nature, Extent and Quality of Services

The Trustees considered the nature, extent and quality of the services that had
been provided by PIM to the Trust, taking into account the investment objective
and strategy of the Trust. The Trustees reviewed the terms of the investment
advisory agreement. The Trustees also reviewed PIM's investment approach for the
Trust and its research process. The Trustees considered the resources of PIM and
the personnel of PIM who provide investment

66 Pioneer Diversified High Income Trust | Annual Report | 4/30/14


management services to the Trust. They also reviewed the amount of non-Trust
assets managed by the portfolio managers of the Trust. The Trustees considered
the non-investment resources and personnel of PIM involved in PIM's services to
the Trust, including PIM's compliance and legal resources and personnel. The
Trustees noted the substantial attention and high priority given by PIM's senior
management to the Pioneer fund complex.

The Trustees considered that PIM supervises and monitors the performance of the
Trust's service providers and provides the Trust with personnel (including Trust
officers) and other resources that are necessary for the Trust's business
management and operations. The Trustees also considered that, as administrator,
PIM is responsible for the administration of the Trust's business and other
affairs. The Trustees considered the fees paid to PIM for the provision of
administration services.

Based on these considerations, the Trustees concluded that the nature, extent
and quality of services that had been provided by PIM to the Trust were
satisfactory and consistent with the terms of the investment advisory agreement.

Performance of the Trust

The Trustees review the Trust's performance on a regular basis, based on
analysis and data prepared by PIM for this purpose and discuss performance
issues with PIM on an ongoing basis. For purposes of their contract renewal
deliberations, the Trustees considered the performance results of the Trust over
various time periods. They reviewed information comparing the Trust's
performance with the performance of its peer group of funds as classified by
Morningstar, Inc. (Morningstar), an independent provider of investment company
data, and with the performance of the Trust's benchmark index. The Trustees
considered that the Trust's annualized total return was in the second quintile
of its Morningstar category for the one year period ended June 30, 2013, in the
third quintile of its Morningstar category for the five year period ended June
30, 2013, and in the fourth quintile of its Morningstar category for the three
year period ended June 30, 2013. The Trustees also considered that the Trust's
yield (for the twelve months ended June 30, 2013) exceeded the yield of the
Trust's benchmark index for the same period. The Trustees also reviewed data
provided by PIM showing how leverage had benefited the Trust's common
shareholders. The Trustees noted the discussions held throughout the year
regarding the Trust's performance and confirmed that those discussions were
factored into the Trustees' deliberations concerning the renewal of the advisory
agreement. They indicated that they were satisfied with the discussions with PIM
with respect to the Trust's performance.

              Pioneer Diversified High Income Trust | Annual Report | 4/30/14 67


Management Fee and Expenses

The Trustees considered information showing the fees and expenses of the Trust
in comparison to the management fees and the expense ratios of a peer group of
funds selected on the basis of criteria determined by the Independent Trustees
for this purpose using data provided by Strategic Insight Mutual Fund Research
and Consulting, LLC (Strategic Insight), an independent third party.

The Trustees considered that the Trust's management fee (based on managed
assets) for the twelve months ended June 30, 2013 was in the fourth quintile
relative to the management fees paid by other funds in its Strategic Insight
peer group for the comparable period. The Trustees also considered that the
Trust's expense ratio (based on managed assets) for the twelve months ended June
30, 2013 was in the fifth quintile relative to its Strategic Insight peer group
for the comparable period. The Trustees noted the investment management
expertise and resources required to implement the Trust's complex investment
strategy given the multiple asset classes in which the Trust invests. The
Trustees also considered that the Trust did not have a clear cut peer group,
noting that other funds in the peer group invested primarily in traditional high
yield bonds.

The Trustees reviewed management fees charged by PIM and PIM's affiliate,
Pioneer Institutional Asset Management, Inc. (together with PIM, "Pioneer") to
institutional and other clients, including publicly offered European funds
sponsored by affiliates of Pioneer, unaffiliated U.S. registered investment
companies (in a sub-advisory capacity), and unaffiliated foreign and domestic
separate accounts. The Trustees also considered PIM's costs in providing
services to the Trust and Pioneer's costs in providing services to the other
clients and considered the differences in management fees and profit margins for
Trust and non-Trust services. In evaluating the fees associated with Pioneer's
client accounts, the Trustees took into account the respective demands,
resources and complexity associated with the Trust and client accounts. The
Trustees noted that, in some instances, the fee rates for those clients were
lower than the management fee for the Trust and considered that, under the
investment advisory agreement with the Trust, PIM performs additional services
for the Trust that it does not provide to those other clients or services that
are broader in scope, including oversight of the Trust's other service providers
and activities related to compliance and the extensive regulatory and tax
regimes to which the Trust is subject. The Trustees also considered the
different entrepreneurial risks associated with PIM's management of the Trust
and Pioneer's management of the other client accounts. The Trustees concluded
that the management fee payable by the Trust to PIM was reasonable in relation
to the nature and quality of the services provided by PIM.

68 Pioneer Diversified High Income Trust | Annual Report | 4/30/14


Profitability

The Trustees considered information provided by PIM regarding the profitability
of PIM with respect to the advisory services provided by PIM to the Trust,
including the methodology used by PIM in allocating certain of its costs to the
management of the Trust. The Trustees also considered PIM's profit margin in
connection with the overall operation of the Trust. They further reviewed the
financial results realized by PIM and its affiliates from non-fund businesses.
The Trustees considered PIM's profit margins with respect to the Trust in
comparison to the limited industry data available and noted that the
profitability of any adviser was affected by numerous factors, including its
organizational structure and method for allocating expenses. The Trustees
concluded that PIM's profitability with respect to the management of the Trust
was not unreasonable.

Economies of Scale

The Trustees considered the extent to which PIM may realize economies of scale
or other efficiencies in managing and supporting the Trust. Since the Trust is a
closed-end fund that has not raised additional capital, the Trustees concluded
that economies of scale were not a relevant consideration in the renewal of the
investment advisory agreement.

Other Benefits

The Trustees considered the other benefits to PIM from its relationship with the
Trust. The Trustees considered the character and amount of fees paid by the
Trust, other than under the investment advisory agreement, for services provided
by PIM and its affiliates. The Trustees further considered the revenues and
profitability of PIM's businesses other than the fund business. The Trustees
considered the intangible benefits to PIM by virtue of its relationship with the
Trust and the other Pioneer funds. The Trustees concluded that the receipt of
these benefits was reasonable in the context of the overall relationship between
PIM and the Trust.

Conclusion

After consideration of the factors described above as well as other factors, the
Trustees, including all of the Independent Trustees, concluded that the
investment advisory agreement between PIM and the Trust, including the fees
payable thereunder, was fair and reasonable and voted to approve the proposed
renewal of the investment advisory agreement for the Trust.

 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.

                 firm, the scope of the Audit

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

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, 2013 and 2014, there were no
services provided to an affiliate that required the
Trust's audit committee pre-approval.


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

N/A

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

The aggregate non-audit fees for the Trust and
affiliates, as previously defined, totaled approximately
$8,290 in 2013 and $8,131 in 2014.

(h) Disclose whether the registrants audit committee of the board of trustees
has considered whether the provision of non-audit services that were rendered to

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 Trust'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

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

ADDITIONAL INFORMATION ABOUT THE PORTFOLIO MANAGERS

OTHER ACCOUNTS MANAGED BY THE PORTFOLIO MANAGERS
The table below indicates, for the portfolio managers of the fund, information
about the accounts other than the fund over which the portfolio manager has
day-to-day investment responsibility. All information on the number of accounts
and total assets in the table is as of April 30, 2014. For purposes of the

POTENTIAL CONFLICTS OF INTEREST
When a portfolio manager is responsible for the management of more than one
account, the potential arises for the portfolio manager to favor one account
over another. The principal types of potential conflicts of interest that may
arise are discussed below. For the reasons outlined below, 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


                                       0


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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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.
