President's Letter

Dear Shareowner,

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

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

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

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

2 Pioneer High Income Trust | Annual Report | 3/31/16


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

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

Sincerely,

/s/ Lisa M. Jones

Portfolio Management Discussion | 3/31/16

Higher-yielding, lower-quality bonds felt the brunt of the negative effects of
falling commodity prices and signs of weakening in the global economy during the
12-month period ended March 31, 2016. In the following interview, Andrew Feltus
discusses the factors that affected the performance of Pioneer High Income Trust
during the 12-month period. Mr. Feltus, Director of High Yield and Bank Loans, a
senior vice president and a portfolio manager at Pioneer, is responsible for the
daily management of the Trust.

Q    How did the Trust perform during the 12-month period ended March 31, 2016?

A    Pioneer High Income Trust returned -10.54% at net asset value and -11.37%
     at market price during the 12-month period ended March 31, 2016. During the
     same 12-month period, the Trust's benchmark, the Bank of America Merrill
     Lynch (BofA ML) US High Yield Index (the BofA ML Index), returned -3.99% at
     net asset value. The BofA ML Index is an unmanaged, commonly accepted
     measure of the performance of high-yield securities. Unlike the Trust, the
     BofA ML Index does not use leverage. While the use of leverage increases
     investment opportunity, it also increases investment risk.

     During the same 12-month period, the average return (at market price) of
     the 31 closed end funds in Lipper's High Yield Closed End Funds category
     (which may or may not be leveraged) was -5.62%.

     The shares of the Trust were selling at a 7.5% premium to net asset value
     at the end of the 12-month period on March 31, 2016.

     On March 31, 2016, the standardized 30-day SEC yield of the Trust's shares
     was 14.84%*.

Q    How would you describe the investment environment for high-yielding debt
     during the 12-month period ended March 31, 2016?

A    The past 12 months featured a challenging market environment for high-
     yield investors, with several factors contributing to the volatility. In
     the fixed-income market, the asset classes with the highest credit
     sensitivity, such as high-yield corporates and emerging markets debt,
     underperformed over most of the period amidst fears about weakening growth
     trends in the global economy and the possibility that the US economy could
     slip back into recession. Weakness in commodity prices, especially oil,
     also took a heavy toll on the high-yield corporate sector, which had a
     large exposure to energy bonds.

*    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.

4 Pioneer High Income Trust | Annual Report | 3/31/16


     In April and May of 2015, the first two months of the Trust's fiscal year,
     high-yield corporates, including energy-sensitive bonds, actually appeared
     to be staging a recovery from the losses they suffered prior to the start
     of the period, as the price of oil briefly bounced back from
     late-2014/early-2015 lows.

     The situation changed in June, however, when oil/commodity prices again
     went into decline due to growing evidence that economic growth in China was
     slackening at the same time that concerns about the state of Europe's
     economy resurfaced, triggered by a renewed debt crisis in Greece.

     While slumping oil prices and global economic news were the main factors
     driving underperformance in the high-yield market during the 12-month
     period, a host of other issues also negatively affected market sentiment,
     including geopolitical concerns and speculation that the US Federal Reserve
     System (the Fed) might aggressively tighten monetary policy. The markets
     expected the Fed to tighten monetary policy in 2015, and it finally did
     raise short-term interest rates in December, after some delay. Since the
     start of 2016, however, the Fed seems to have taken a more dovish stance on
     interest rates, thus reassuring the markets that it would act cautiously
     before tightening monetary policy any further.

     High-yield investments did rally in the final six weeks of the Trust's
     fiscal year, beginning in mid-February 2016. Unfortunately, the rebound was
     not strong enough to overcome the effects of the market's earlier losses.

Q    Which of your investment decisions or other factors had the biggest effects
     on the Trust's benchmark-relative underperformance during the 12-month
     period ended March 31, 2016?

A    The main reason for the Trust's underperformance of its benchmark during
     the period was the use of leverage, or borrowed funds. The use of leverage
     increases the Trust's risk and has the effect of exaggerating the size of
     the high-yield market's moves on the portfolio. In down markets, when high-
     yield securities are underperforming and bond prices are falling, as was
     the case during the 12-month period, the use of leverage can and will
     negatively affect the Trust's benchmark-relative performance. As high-yield
     bond investments lost value during the period, the effects of leverage on
     the Trust's returns were magnified.

     Another factor that detracted from benchmark-relative performance was the
     Trust's greater exposure than that of the BofA ML Index, early in the
     period, to securities issued by energy companies, particularly those
     involved in exploration and production. As oil prices fell during the third
     quarter of 2015 when it became apparent that the rebalancing in the oil
     sector would be a longer process than the market originally expected,
     energy bond prices experienced downward pressure. We subsequently

                           Pioneer High Income Trust | Annual Report | 3/31/16 5


     reduced the Trust's exposure to the energy sector from slightly more than
     14% of the Trust's total investment portfolio at the beginning of the
     period (compared with 13.7% for the benchmark), to 9.4% as of March 31,
     2016 (compared with 12.7% for the benchmark). Individual positions in the
     portfolio's energy sector also underperformed and detracted from
     benchmark-relative returns. Notable underperformers among the oil-related
     securities in the Trust's portfolio were the debt of Comstock and Midstates
     Petroleum, both of which we expect to be restructured.

     In addition, the Trust's shorter-duration stance hurt benchmark-relative
     returns during the 12-month period. (Duration is a measure of the
     sensitivity of the price, or the value of principal, of a fixed-income
     investment to a change in interest rates, expressed as a number of years.)
     We pursue a buy-and-hold strategy in the Trust's portfolio, retaining those
     high-current-income securities that we believe can support a healthy
     dividend** stream to the Trust's shareholders. Therefore, we tend to keep
     the Trust's duration shorter than that of the BofA ML Index due to the
     allocation to older securities with higher yields. The shorter-duration
     stance should also decrease the portfolio's sensitivity to changes in
     interest rates and credit spreads. During the 12-month period ended March
     31, 2016, however, mid- and long-term US Treasury interest rates fell.
     Given that the Trust was positioned for a rising-rate environment, the
     portfolio's short-duration stance detracted from the Trust's
     benchmark-relative performance.

Q    Which allocation decisions or individual investments had the greatest
     positive effects on the Trust's benchmark-relative performance during the
     12-month period ended March 31, 2016?

A    The Trust's moderate overweight in securities issued by banks and moderate
     underweight to non-bank financial companies tended to support
     benchmark-relative performance during the period. Individual positions in
     the debt of Ally Financial, a specialist in automobile financing, and in
     securities issued by Bank of America and PNC Bank were particularly
     noteworthy contributors to relative returns. Holdings of utility bonds such
     as NRG Energy, which we added to during the period, also aided relative
     performance after the securities rebounded during the second half of the
     Trust's fiscal year. We likewise had success investing in debt of
     automobile-related companies during a year when car sales were healthy.
     The debt of Meritor, an auto parts component manufacturer, and of Chrysler
     Group, both fared well and contributed to the Trust's performance. Finally,
     investments in some emerging markets corporates did well during the period,
     as did the portfolio's positions in insurance-linked bonds, an asset class
     that turned in strong performance during a relatively mild hurricane season
     in the United States.

6 Pioneer High Income Trust | Annual Report | 3/31/16


Q    What were the principal factors affecting the Trust's yield, or dividend
     income, during the 12-month period ended March 31, 2015?

A    The Trust's dividend to shareholders was reduced in February 2016 because
     the portfolio of investments was realizing less current income. Over the
     12-month period, yields of newer high-yield bonds tended to be lower than
     the yields of older bonds issued back when market rates were higher. As the
     period progressed, many of the older holdings in the Trust's portfolio
     either had reached maturity or were called away by their issuers, who often
     replaced them with newer bonds paying lower interest rates. In addition,
     the Trust has drawn on accumulated net investment income in paying the
     Trust's distributions in recent periods, but these reserves will be
     depleted over time. Therefore, as the Trust redeployed assets in a
     lower-yielding market, the income earned by the portfolio's investments
     declined. Likewise, the decision by the Fed to raise interest rates last
     December increased the cost of leverage to the Trust and reduced the income
     available for distribution.

Q    Did the level of leverage in the Trust change during the 12-month period
     ended March 31, 2016?

A    The Trust employs leverage through a margin loan financing agreement. (See
     Note 10 to the Financial Statements).

     At the end of the 12-month period on March 31, 2016, 31.5% of the Trust's
     total managed assets were financed by leverage (or borrowed funds),
     compared with 30.5% of the Trust's total managed assets financed by
     leverage at the start of the period on April 1, 2015. During the 12-month
     period, the Trust reduced the borrowing from the revolving credit facility
     by a total of $26 million, to $125 million as of March 31, 2016. Due to the
     overall decline in prices of high-yield securities during the period, a
     reduction in the overall borrowing on the margin line was necessary in
     order to maintain the asset-coverage requirements specified by the margin
     loan financing agreement. Despite the reduction, the percentage of the
     Trust's managed assets financed by leverage increased during the period due
     to a decrease in the values of securities in which the Trust had invested.

Q    Did the Trust invest in any derivative securities during the 12-month
     period ended March 31, 2016? If so, did the exposure have a material impact
     on performance?

A    We did invest in some currency forward exchange transactions in an attempt
     to hedge the effects on the Trust's portfolio of changes in relative
     currency valuations during the period. The derivatives did not have a
     material impact on benchmark-relative results. The Trust also had a small
     exposure to some credit default swaps, which had no material effect on
     relative performance, but had a small positive effect on absolute
     performance.

                           Pioneer High Income Trust | Annual Report | 3/31/16 7


Q    What is your investment outlook?

A    While domestic economic growth has slowed somewhat during the past year, we
     do not see evidence that the US economy is heading into recession. In a
     period of continued, if modest, growth, we believe there should be
     opportunities for investment in credit-sensitive securities, especially if
     they are attractively priced.

     Spreads between high-yield and higher-quality bonds are wider now than the
     longer-term averages, and wider than they were a year ago. (Credit spreads
     are commonly defined as the differences in yield between Treasuries and
     other types of fixed-income securities with similar maturities.) At the
     same time, high-yield default rates, while higher than a year ago, remain
     below long-term averages. The troubled high-yield debt seems concentrated
     in the energy, and metals and mining groups, while most other sectors
     appear to be doing better. The most recent default rate for high-yield
     bonds stood at 3.8%, while current market prices suggest a default rate of
     8% to 10%. This indicates there may be value in the high-yield market.

     We believe the biggest threat to continued expansion of the domestic
     economy would be aggressive monetary policy tightening by the Fed. However,
     the Fed, as we noted earlier, appears satisfied, at least for now, to move
     at a slower pace with regard to hiking interest rates. We think it is
     likely, though, that the Fed will increase short-term interest rates
     modestly (only once or twice) during 2016 as it keeps a close watch on
     economic data. Meanwhile, in an election year, budgetary policy in
     Washington may loosen somewhat, as evidenced by the recent passage of a
     Federal Highway Bill, which should provide some stimulus to the economy.

     After a year of underperformance, we think high-yield bond pricing is more
     attractive, with above-average spreads and below-average default rates.
     While we do not anticipate a robust rally in the high-yield market, and
     while short-term market swings may continue to be volatile, we think there
     may be opportunities in the high-yield market for appropriate investors.

Please refer to the Schedule of Investments on pages 13-38 for a full listing of
Trust securities.

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

Investments in high-yield or lower-rated securities are subject to greater-than-
average risk.

8 Pioneer High Income Trust | Annual Report | 3/31/16


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 fixed-income securities in the Trust
will generally fall. Conversely, when interest rates fall the prices of
fixed-income securities in the Trust will generally rise.

Investments in the Trust are subject to possible loss due to the financial fail-
ure of the issuers of the underlying securities and their inability to meet
their debt obligations.

The Trust may invest up to 50% of its total assets in illiquid securities.
Illiquid securities may be difficult to dispose of at a price reflective of
their value at the times when the Trust believes it is desirable to do so, and
the market price of illiquid securities is generally more volatile than that of
more liquid securities. Illiquid securities are also 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 employs leverage through a margin loan financing agreement. 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 leverage, which may
adversely affect the return for shareowners.

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

Risks of investing in the Trust are discussed in greater detail in the Trust's
original offering documents relating to its common shares and shareowner reports
issued from time to time.

These risks may increase share price volatility.

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. Past performance is no
guarantee of future results.

future results.

*    The amount of distributions made to shareowners during the period was in
     excess of the net investment income earned by the Trust during the period.
     The Trust has accumulated undistributed net investment income which is part
     of the Trust's NAV. A portion of this accumulated net investment income was
     distributed to shareowners during the period. A decrease in distributions
     may have a negative effect on the market value of the Trust's shares.

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

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

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

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

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

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

The Bank of America Merrill Lynch US High Yield Index is an unmanaged, commonly
accepted measure of the performance of high yield securities. Index returns are
calculated monthly, assume reinvestment of dividends and, unlike Trust
returns, do not reflect any fees, expenses or sales charges. The Index does not
employ leverage. It is not possible to invest directly in the Index.

Notes to Financial Statements | 3/31/16

1. Organization and Significant Accounting Policies

Pioneer High Income Trust (the Trust) was organized as a Delaware statutory
trust on January 30, 2002. Prior to commencing operations on April 26, 2002, the
Trust had no operations other than matters relating to its organization and
registration as a diversified, closed-end management investment company under
the Investment Company Act of 1940, as amended. The investment objective of the
Trust is to seek a high level of current income and the Trust may, as a
secondary objective, also seek capital appreciation to the extent that it is
consistent with its investment objective.

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

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

A.   Security Valuation

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

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

     Loan interests are valued in accordance with guidelines established by the
     Board of Trustees at the mean between the last available bid and asked
     prices from one or more brokers or dealers as obtained from Loan Pricing
     Corporation, an independent third party pricing service. If price
     information is not available from Loan Pricing Corporation, or if the price
     information is

                          Pioneer High Income Trust | Annual Report | 3/31/16 45


     deemed to be unreliable, price information will be obtained from an
     alternative loan interest pricing service. If no reliable price quotes are
     available from either the primary or alternative pricing service, broker
     quotes will be solicited.

     Event-linked bonds or catastrophe bonds are valued at the bid price
     obtained from an independent third party pricing service. Other insurance
     linked securities (including sidecars, collateralized reinsurance and
     industry loss warranties) may be valued at the bid price obtained from an
     independent pricing service, or through a third party using a pricing
     matrix, insurance industry valuation models, or other fair value methods or
     techniques to provide an estimated value of the instrument.

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

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

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

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

46 Pioneer High Income Trust | Annual Report | 3/31/16


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

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

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

     At March 31, 2016, eleven securities were valued using fair value methods
     (in addition to securities valued using prices supplied by independent
     pricing services or broker-dealers) representing 2.44% of net assets. The
     value of these fair valued securities are $6,625,612.

B.   Investment Income and Transactions

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

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

                          Pioneer High Income Trust | Annual Report | 3/31/16 47


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

C.   Foreign Currency Translation

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

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

D.   Forward Foreign Currency Contracts

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

E.   Federal Income Taxes

     It is the Trust's policy to comply with the requirements of the Internal
     Revenue Code applicable to regulated investment companies and to distribute
     all of its net taxable income and net realized capital gains, if any, to
     its shareowners. Therefore, no federal income tax provision is required. As
     of March 31, 2016, the Trust did not accrue any interest or penalties with
     respect to uncertain tax positions, which if applicable, would be recorded
     as an income tax expense in the Statement of Operations. Tax returns filed
     within the prior three years remain subject to examination by federal and
     state tax authorities.

     The amount and character of income and capital gain distributions to
     shareowners are determined in accordance with federal income tax rules,
     which may differ from U.S. generally accepted accounting principles.

48 Pioneer High Income Trust | Annual Report | 3/31/16


     Distributions in excess of net investment income or net realized gains are
     temporary overdistributions for financial statement and tax purposes.
     Capital accounts within the financial statements are adjusted for permanent
     book/tax differences to reflect tax character, but are not adjusted for
     temporary differences.

     At March 31, 2016, the Trust reclassified $610,570 to decrease paid in
     capital, $925,852 to decrease distributions in excess of net investment
     income and $315,282 to increase accumulated net realized loss on
     investments to reflect permanent book/tax differences. These adjustments
     have no impact on the net assets or results of operations.

     At March 31, 2016, the Trust was permitted to carry forward $7,059,380 of
     short-term capital losses and $20,887,161 of long-term capital losses
     without limitation. Additionally, at March 31, 2016, the Trust had a net
     capital loss carry forward of $44,356,204 of which the following amounts
     will expire between 2016 and 2019 if not utilized: $42,238,794 in 2018, and
     $2,177,410 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 $1,313,408 of short-term capital losses and
     $21,012,015 of long-term capital losses recognized between October 1, 2015
     and March 31, 2016 to its fiscal year ending March 31, 2017.

     The tax character of distributions paid to shareowners during the years
     ended March 31, 2016 and March 31, 2015 were as follows:



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

     Distributions paid from:

     The following shows the components of distributable earnings (losses) on a
     federal income tax basis at March 31, 2016:

     Unrealized depreciation                                        (46,803,268)
     ---------------------------------------------------------------------------
        Total                                                     $(143,003,766)
     ===========================================================================


                          Pioneer High Income Trust | Annual Report | 3/31/16 49


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

F.   Insurance Linked Securities (ILS)

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

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

     Structured reinsurance investments, including quota share instruments,
     collateralized reinsurance investments and ILW's generally are subject to
     the same risks as event-linked bonds. In addition, where the instruments
     are based on the performance of underlying reinsurance contracts, the Trust
     has limited transparency into the individual underlying contracts and
     therefore must rely upon the risk assessment and sound underwriting
     practices of the issuer. Accordingly, it may be more difficult for PIM to
     fully evaluate the underlying risk profile of the Trust's structured
     reinsurance investments and therefore the Trust's assets are placed at
     greater risk of loss than if PIM had more complete information. Structured
     reinsurance instruments generally

50 Pioneer High Income Trust | Annual Report | 3/31/16


     will be considered illiquid securities by the Trust. These securities may
     be difficult to purchase, sell or unwind. Illiquid securities also may be
     difficult to value. If the Trust is forced to sell an illiquid asset, the
     Trust may be forced to sell at a loss.

G.   Risks

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

     The Trust invests in below investment grade (high yield) debt securities,
     floating rate loans and event-linked bonds sometimes referred to as
     "catastrophe" bonds or "insurance-linked" bonds. The Trust may invest in
     securities and other obligations of any credit quality, including those
     that are rated below investment grade, or are unrated but are determined by
     the investment adviser to be of equivalent credit quality. Below investment
     grade securities are commonly referred to as "junk bonds" and are
     considered speculative with respect to the issuer's capacity to pay
     interest and repay principal. Below investment grade securities, including
     floating rate loans, involve greater risk of loss, are subject to greater
     price volatility, and are less liquid and more difficult to value,
     especially during periods of economic uncertainty or change, than higher
     rated debt securities. The trust may invest in securities of issuers that
     are in default or that are in bankruptcy. The value of collateral, if any,
     securing a floating rate loan can decline or may be insufficient to meet
     the issuer's obligations or may be difficult to liquidate. No active
     trading market may exist for many floating rate loans, and many loans are
     subject to restrictions on resale. Any secondary market may be subject to
     irregular trading activity and extended settlement periods. The Trust's
     investments in certain foreign markets or countries with limited developing
     markets may subject the Trust to a greater degree of risk than in a
     developed market. These risks include disruptive political or economic
     conditions and the possible imposition of adverse governmental laws or
     currency exchange restrictions. The Trust may invest up to 50% of its total
     assets in illiquid securities. Illiquid securities are securities that
     cannot be disposed of by the Trust within seven days in the ordinary course
     of business at approximately the amounts which the Trust values the
     securities.

                          Pioneer High Income Trust | Annual Report | 3/31/16 51


H.   Repurchase Agreements

     Repurchase agreements are arrangements under which the Trust purchases
     securities from a broker-dealer or a bank, called the counterparty, upon
     the agreement of the counterparty to repurchase the securities from the
     Trust at a later date, and at a specific price, which is typically higher
     than the purchase price paid by the Trust. The securities purchased serve
     as the Trust's collateral for the obligation of the counterparty to
     repurchase the securities. The value of the collateral, including accrued
     interest, is required to be equal to or in excess of the repurchase price.
     The collateral for all repurchase agreements is held in safekeeping in the
     customer-only account of the Trust's custodian or a subcustodian of the
     Trust. The Trust's investment adviser, PIM is responsible for determining
     that the value of the collateral remains at least equal to the repurchase
     price. In the event of a default by the counterparty, the Trust is entitled
     to sell the securities, but the Trust may not be able to sell them for the
     price at which they were purchased, thus causing a loss to the Trust.
     Additionally, if the counterparty becomes insolvent, there is some risk
     that the Trust will not have a right to the securities, or the immediate
     right to sell the securities.

I.   Automatic Dividend Reinvestment Plan

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

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

     Whenever the Trust declares a dividend on shares payable in cash,
     participants in the Plan will receive the equivalent in shares acquired by
     the Plan Agent either (i) through receipt of additional unissued but
     authorized shares from the Trust or (ii) by purchase of outstanding shares
     on the New

52 Pioneer High Income Trust | Annual Report | 3/31/16


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

J.   Credit Default Swap Agreements

     A credit default swap is a contract between a buyer of protection and a
     seller of protection against a pre-defined credit event. The Trust may buy
     or sell credit default swap contracts to seek to increase the Trust's
     income, or to attempt to hedge the risk of default on portfolio securities.
     A credit default swap index is used to hedge risk or take a position on a
     basket of credit entities or indices. As a seller of protection, the Trust
     would be required to pay the notional (or other agreed-upon) value of the
     referenced debt obligation to the counterparty in the event of a default by
     a U.S. or foreign corporate issuer of a debt obligation, which would likely
     result in a loss to the Trust. In return, the Trust would receive from the
     counterparty a periodic stream of payments during the term of the contract
     provided that no event of default occurred. The maximum exposure of loss to
     the seller would be the notional value of the credit default swaps
     outstanding. If no default occurs, the Trust would keep the stream of
     payments and would have no payment obligation. The Trust may also buy
     credit default swap contracts in order to hedge against the risk of default
     of debt securities, in which case the Trust would function as the
     counterparty referenced above.

     When the Trust enters into a credit default swap contract, the protection
     buyer makes an upfront or periodic payment to the protection seller in
     exchange for the right to receive a contingent payment. An upfront payment
     made by the Trust, as the protection buyer, is recorded as an asset in the
     Statement of Assets and Liabilities. Periodic payments received or paid by
     the Trust are recorded as realized gains or losses in the Statement of
     Operations.

                          Pioneer High Income Trust | Annual Report | 3/31/16 53


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

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

     Open credit default swap contracts at March 31, 2016 are listed in the
     Schedule of Investments.

     The average market value of swap contracts open during the year ended March
     31, 2016 was $195,994.

     The amount of cash deposited with the broker as collateral at March 31,
     2016, and is included in "Restricted cash" in the Statement of Assets and
     Liabilities, was $135,000.

K.   Interest Rate Swap Contracts

     The Trust may enter into interest rate swaps to attempt to hedge against
     interest rate fluctuations or to enhance its income. Pursuant to the
     interest rate swap agreement, the Trust negotiates with a counterparty to
     exchange a periodic stream of payments based on a benchmark interest rate.
     One cash flow stream will typically be a floating rate payment based upon
     the specified floating benchmark interest rate while the other is typically
     a fixed interest rate. Payment flows are usually netted against each other,
     with the difference being paid by one party to the other on a monthly
     basis.

     Periodic payments received or paid by the Trust are recorded as realized
     gains or losses in the Statement of Operations. Interest rate swap
     contracts are marked-to-market daily using valuations supplied by
     independent sources and the change in value, if any, is recorded as
     unrealized appreciation or depreciation in the Statement of Assets and
     Liabilities. Interest rate swap contracts are subject to counterparty risk
     and movements in interest rates.

54 Pioneer High Income Trust | Annual Report | 3/31/16


     Certain swap contracts that are cleared through a central clearinghouse are
     referred to as centrally cleared swaps. All payments made or received by
     the Trust are pursuant to a centrally cleared swap contract with the
     central clearing party rather than the original counterparty. Upon entering
     into a centrally cleared swap contract, the Trust is required to make an
     initial margin deposit, either in cash or in securities. The daily change
     in value on open centrally cleared swap contracts is recorded as variation
     margin on centrally cleared swaps on the Statement of Assets and
     Liabilities.

     Open interest rate swap contracts at March 31, 2016 are listed in the
     Schedule of Investments.

     The average value of interest rate swap contracts open during the year
     ended March 31, 2016 was $(94,674).

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 0.60% 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 March 31, 2016, the net management fee
was 0.60% of the Trust's average daily managed assets, which was equivalent to
0.88% 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 March 31,
2016, $181,792 was payable to PIM related to management costs, administrative
costs and certain other services is included in "Due to affiliates" and
"Administration fee" on the Statement of Assets and Liabilities.

3. Transfer Agents

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

Effective November 2, 2015, AST serves as the transfer agent with respect to the
Trust's common shares. The Trust pays AST an annual fee, as is agreed to from
time to time by the Trust and AST, for providing such services.

                          Pioneer High Income Trust | Annual Report | 3/31/16 55


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

4. Forward Foreign Currency Contracts

During the year ended March 31, 2016, the Trust had entered into various forward
foreign currency contracts that obligate the Trust to deliver or take delivery
of currencies at specified future maturity dates. Alternatively, prior to the
settlement date of a forward foreign currency contract, the Trust may close out
such contract by entering into an offsetting contract.

The average value of contracts open during the year ended March 31, 2016 was
$(4,723,646).

Open foreign currency contracts at March 31, 2016, were as follows:

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


5. Assets and Liabilities Offsetting

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

56 Pioneer High Income Trust | Annual Report | 3/31/16


reduction of the Trust's credit risk to its counterparty equal to any amounts
payable by the Trust under the applicable transactions, if any. However, the
Trust's right to setoff may be restricted or prohibited by the bankruptcy or
insolvency laws of the particular jurisdiction to which a specific ISDA
counterparty is subject.

The collateral requirements for derivatives transactions under an ISDA Master
Agreement are governed by a credit support annex to the ISDA Master Agreement.
Collateral requirements are generally determined at the close of business each
day and are typically based on changes in market values for each transaction
under an ISDA Master Agreement and netted into one amount for such agreement.
Generally, the amount of collateral due from or to a counterparty is subject to
threshold (a "minimum transfer amount") before a transfer is required, which may
vary by counterparty. Collateral pledged for the benefit of the Trust and/or
counterparty is held in segregated accounts by the Trust's custodian and cannot
be sold, re-pledged, assigned or otherwise used while pledged. Cash that has
been segregated to cover the Trust's collateral obligations, if any, will be
reported separately in the Statement of Assets and Liabilities as "Restricted
Cash". Securities pledged by the Trust as collateral, if any, are identified as
such in the Schedule of Investments.

Financial instruments subject to an enforceable master netting agreement such as
an ISDA Master Agreement have not been offset on the Statement of Assets and
Liabilities. The following charts show gross assets and liabilities of the Trust
as of March 31, 2016:

6. Additional Disclosures about Derivative Instruments and Hedging Activities

The Trust's use of derivatives subjects it to the following risks:

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

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

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

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

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

The fair value of open derivative instruments (not considered to be hedging
instruments for accounting disclosure purposes) by risk exposure at March 31,
2016 was as follows:

7. Bridge Loan Commitments

Bridge loans are designed to provide temporary or "bridge" financing to a
borrower pending the sale of identified assets or the arrangement of longer term
loans or the issuance and sale of debt obligations.

As of March 31, 2016, the Trust had two bridge loan commitments of $1,807,971,
which could be extended at the option of the borrower, pursuant to the following
loan agreements:

9. Margin Loan Financing

The Trust has entered into a margin loan financing agreement with Credit Suisse.
The margin loan is offered at a daily rate equal to the U.S. three-month LIBOR
rate plus 0.70%. There is no fixed borrowing limit.

At March 31, 2016, the Trust had a borrowing outstanding under the margin
agreement totaling $125,000,000. The interest rate charged at March 31, 2016 was
2.38%. During the year ended March 31, 2016, the average daily balance was
$144,694,823 at an average interest rate of 1.39%. With respect to the margin
agreement, interest expense of $1,938,750 is included in the Statement of
Operations.

The Trust is required to fully collateralize its outstanding loan balance as
determined by Credit Suisse. Pledged assets are held in a segregated account and
are denoted in the Schedule of Investments.

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

10. Subsequent Events

A monthly dividend was declared on April 4, 2016 from undistributed and
accumulated net investment income of $0.0950 per share payable April 29, 2016,
to shareowners of record on April 15, 2016.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees and the Shareowners of Pioneer High Income Trust:
--------------------------------------------------------------------------------
We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Pioneer High Income Trust (the "Trust") as of
March 31, 2016, and the related statements of operations and cash flows for the
year then ended and the statements of changes in net assets and the financial
highlights for each of the two years in the period then ended. These financial
statements and financial highlights are the responsibility of the Trust's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audits. The financial
highlights for the years ended March 31, 2014, 2013, and 2012 were audited by
other auditors. Those auditors expressed an unqualified opinion on those
financial highlights in their report dated May 22, 2014.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. The Trust
is not required to have, nor were we engaged to perform, an audit of its
internal control over financial reporting. Our audits included consideration of
internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Trust's internal control over
financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of March 31, 2016, by correspondence with the custodian,
brokers and agent banks; where replies were not received from brokers and agent
banks, we performed other auditing procedures. We believe that our audits
provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Pioneer High Income Trust as of March 31, 2016, the results of its operations
and its cash flows for the year then ended and the changes in its net assets and
the financial highlights for each of the two years in the period then ended, in
conformity with accounting principles generally accepted in the United States of
America.

ADDITIONAL INFORMATION (unaudited)

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

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

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

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

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

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

                  SECTION I - POLICY PURPOSE AND APPLICABILITY

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

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

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

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

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

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


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

Non-Audit Services
Beginning with non-audit service contracts entered
into on or after May 6, 2003, the effective date of the
new SEC pre-approval rules, the Trust's audit
committee is required to pre-approve services to
affiliates defined by SEC rules to the extent that the
services are determined to have a direct impact on the
operations or financial reporting of the Trust.  For the
years ended March 31 2016 and 2015, there were no
services provided to an affiliate that required the
Trust's audit committee pre-approval.


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

with the adviser that provides ongoing services to the registrant for each of
the last two fiscal years of the registrant.

The aggregate non-audit fees for the Trust were $9,904

investment adviser), and any entity controlling, controlled by, or under common
control with the investment adviser that provides ongoing services to the
registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of
Rule 2-01 of Regulation S-X is compatible with maintaining the principal
accountant's independence.

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

ITEM 5. AUDIT COMMITTEE OF LISTED REGISTRANTS

(a) If the registrant is a listed issuer as defined in Rule 10A-3
under the Exchange Act (17 CFR 240.10A-3), state whether

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

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

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

                            VERSION DATED July, 2004

                                    Overview

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

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

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

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

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

                                       1


                             Proxy Voting Procedures

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

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

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

                                       2


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

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

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

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

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

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

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

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

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

                                       3


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

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

   Share-Blocking

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

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

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

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

       o   Retains a record of the vote cast;

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

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

                                       4


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

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

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

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

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

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

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

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

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

                                       5


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

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

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

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

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

   We will generally support these and similar management proposals:

       o    Corporate name change.

       o    A change of corporate headquarters.

       o    Stock exchange listing.

       o    Establishment of time and place of annual meeting.

       o    Adjournment or postponement of annual meeting.

       o    Acceptance/approval of financial statements.

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

       o    Approval of minutes and other formalities.

                                       6


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

       o    Amendments to authorized signatories.

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

       o    Acceptance of labor agreements.

       o    Appointment of internal auditors.

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

Auditors
     We normally vote for proposals to:

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

       o    Restore shareholder rights to ratify the auditors.

     We will normally oppose proposals that require companies to:

       o    Seek bids from other auditors.

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

       o    Indemnify auditors.

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

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

                                       7


     General Board Issues
     Pioneer will vote for:

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

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

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

       o    Election of an honorary director.

     We will vote against:

       o    Minimum stock ownership by directors.

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

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

       o    Requirements to provide two candidates for each board seat.

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

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

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

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

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

     We will also vote against:

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

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

                                       8


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

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

       o    Contested election of directors.

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

       o    Mandatory retirement policies.

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

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

     Pioneer will vote for:

       o    Cumulative voting.

       o    Increase ability for shareholders to call special meetings.

       o    Increase ability for shareholders to act by written consent.

       o    Restrictions on the ability to make greenmail payments.

       o    Submitting rights plans to shareholder vote.

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

       o    Opting out of the following state takeover statutes:

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

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

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

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

                                       9


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

     o Fair price provisions.

     o Authorization of shareholder rights plans.

     o Labor protection provisions.

     o Mandatory classified boards.

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

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

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

       o    Proposals that allow shareholders to nominate directors.

     We will vote against:

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

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

       o    Classes of shares with unequal voting rights.

       o    Supermajority vote requirements.

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

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

       o    Extension of advance notice requirements for shareholder proposals.

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

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

                                       10


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

     Pioneer will vote for:

       o    Changes in par value.

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

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

       o    Bond issuance.

       o    Increases in "ordinary" preferred stock.

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

       o    Cancellation of company treasury shares.

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

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

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

     o Number of shares currently available for issuance;

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

     o Proposed use of the additional shares; and

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

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

       o    Proposals to submit private placements to shareholder vote.

       o    Other financing plans.

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

                                      11


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

     Pioneer will vote for:

       o    401(k) benefit plans.

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

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

     o Amendments to performance plans to conform with OBRA;

     o Caps on annual grants or amendments of administrative features;

     o Adding performance goals; and

     o Cash or cash-and-stock bonus plans.

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

       o    Require that option repricings be submitted to shareholders.

       o    Require the expensing of stock-option awards.

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

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

                                       12


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

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

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

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

            A = Shares reserved for plan/amendment,

            B = Shares available under continuing plans,

            C = Shares granted but unexercised and

            D = Shares outstanding.

       o    The plan must not:

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

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

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

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

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

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

       o    All other employee stock purchase plans.

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

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

                                       13


     We will vote against:

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

       o    Elimination of stock option plans.

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

       o    Limits on executive and director pay.

       o    Stock in lieu of cash compensation for directors.

     Corporate Governance
     Pioneer will vote for:

       o    Confidential Voting.

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

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

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

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

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

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

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

     We will vote against:

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

       o    Limitations on stock ownership or voting rights.

       o    Reduction in share ownership disclosure guidelines.

                                       14


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

       o    Mergers and acquisitions.

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

       o    Debt restructurings.

       o    Conversion of securities.

       o    Issuance of shares to facilitate a merger.

       o    Private placements, warrants, convertible debentures.

       o    Proposals requiring management to inform shareholders of merger
            opportunities.

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

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

     Pioneer will vote for:

       o    Establishment of new classes or series of shares.

       o    Establishment of a master-feeder structure.

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

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

       o    Approval of new or amended advisory contracts.

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

       o    Authorization for, or increase in, preferred shares.

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

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

                                       15


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

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

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

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

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

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

                                       16



ITEM 8. PORTFOLIO MANAGERS OF CLOSED-END MANAGEMENT INVESTMENT COMPANIES.

(a) If the registrant is a closed-end management investment company that
is filing an annual report on this Form N-CSR,provide the following
information:
(1) State the name, title, and length of service of the person or persons
employed by or associated with the registrant or an investment adviser
of the registrant who are primarily responsible for the day-to-day management

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

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


                                       0


 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 MANAGER
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


                                       1


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 Bank of America Merrill Lynch
  High Yield Master II 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.


SHARE OWNERSHIP BY PORTFOLIO MANAGER
The following table indicates as of March 31, 2016 the value, within the

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

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

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


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

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


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


ITEM 11. CONTROLS AND PROCEDURES.

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

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


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

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

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

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


ITEM 12. EXHIBITS.

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

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



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

Filed herewith.
