President's Letter

Dear Shareowner,

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

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

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

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

Portfolio Management Discussion | 3/31/14

The credit-sensitive sectors, led by domestic high-yield corporate bonds, staged
a brisk comeback in the second half of the 12-month period ended March 31, 2014.
As a result, the high-yield market delivered healthy returns for the full
period, despite early volatility stemming from concerns about potential changes
to the U.S. Federal Reserve System's (the Fed's) monetary policies and worries
about the durability of the economic recovery. 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 months ended March 31, 2014?

A    Pioneer High Income Trust returned 10.32% at net asset value and 16.24% at
     market price during the 12-month period ended March 31, 2014. During the
     same 12-month period, the Trust's benchmark, the Bank of America Merrill
     Lynch (BofA ML) High Yield Master II Index, returned 7.53% at net asset
     value. The BofA ML High Yield Master II Index is an unmanaged, commonly
     accepted measure of the performance of high-yield securities. Unlike the
     Trust, the BofA ML High Yield Master II 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 32 closed-end funds in Lipper's High Current Yield
     Closed End Funds category (which may or may not be leveraged) was 5.01%.

     The shares of the Trust were selling at a 25.7% premium to net asset value
     at the end of the 12-month period on March 31, 2014.

     On March 31, 2014, the standardized 30-day SEC yield of the Trust's shares
     was 6.73%*.

Q    How would you describe the investment environment for high-yield bonds
     during the 12-month period ended March 31, 2014?

A    The backdrop for investing in high-yield bonds and other credit-sensitive
     securities was challenging during the first half of the Trust's fiscal
     year. The most immediate cause of volatility in the bond markets was the
     market's reaction in May 2013 to then-Fed Chair Ben Bernanke's suggestion
     that the Fed might begin tapering its quantitative easing (QE) bond-buying
     program, which had been a key part of the Fed's accommodative monetary
     policies that had helped to keep interest rates low and provided a measure

*    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.

     of support to overall economic growth. The suggestion raised fears of
     rising interest rates, which became a self-fulfilling prophecy and led to a
     sell-off of the fixed-income markets in the second calendar quarter of
     2013. Investors also began to worry about the vitality of the domestic
     economic recovery as new-job creation continued to be weak and corporate
     profit gains appeared to slow. In that environment, fixed-income
     investments in general produced lackluster returns, with credit-sensitive
     securities particularly hard hit on worries about potentially slowing
     economic growth.

     The fears abated and the market for credit-sensitive securities recovered
     in the second half of the 12-month period, as more evidence accumulated
     that the U.S. economy was gathering strength. Improving employment and
     housing trends were some of the encouraging economic signs, and inflation,
     meanwhile, remained in check. Investors also began to anticipate that any
     monetary tightening by the Fed - based on follow-up statements made by Mr.
     Bernanke after his "tapering" comments in May 2013 - would be done
     gradually and in response to new evidence of economic strengthening.
     Moreover, the transition of leadership at the Fed in early 2014 from Mr.
     Bernanke to new Chair Janet Yellen appeared to signal confirmation of a
     gradual evolution of monetary policy rather than an abrupt change. The Fed
     ended up delaying its official announcement regarding the tapering of QE
     until December of 2013, and began reducing its monthly bond purchases in
     2014, with the eventual goal being to fully draw down the QE program by the
     end of the current calendar year.

     On the political front, a late-2013 bipartisan agreement establishing
     top-line Federal spending levels for the next two fiscal years seemed to,
     temporarily at least, put an end to the constant bickering between
     Democrats and Republicans in Washington over the nation's fiscal course,
     and that news also buoyed market sentiment. In addition, investors were
     encouraged that fiscal policy would be less of a factor holding back the
     economy's growth potential, as spending cuts at the Federal level
     ("sequestration") were slated to be eased as part of the bipartisan budget
     agreement.

     As the markets grew calmer over the final half of the Trust's fiscal year,
     high-yield and investment-grade corporate bonds as well as most other
     credit-sensitive securities tended to perform well, while U.S. Treasuries
     and government agency debt came under pressure when market interest rates
     for most maturities rose. Yield spreads (the differences in yields between
     credit-sensitive debt and Treasuries of similar maturity) also tightened as
     the credit sectors outperformed Treasuries.

     Outside the U.S., growth trends appeared to be improving both in Europe and
     Japan, although China and the emerging markets clearly tailed off during
     the period. The European economy responded well to monetary

                           Pioneer High Income Trust | Annual Report | 3/31/14 5


     support from the European Central Bank and the accompanying relaxation of
     fiscal constraints that had helped to dampen growth. In Japan, meanwhile,
     the loosening of both monetary and fiscal policy had helped stimulate the
     country's economy, even in the face of disappointing structural reforms and
     tax increases in 2014. The worries about slowing growth in China had
     repercussions in many of the emerging markets, mainly due to the effects of
     declining commodity prices. Currencies of emerging markets economies
     dependent on the flow of capital from the United States also became more
     volatile amid worries about looming monetary tightening by the Fed.

Q    Which individual securities or investment decisions had the biggest effects
     on the Trust's performance during the 12-month period ended March 31, 2014?

A    The Trust performed well during the period, helped by strong security
     selection results among high-yield corporate bonds, our heavy emphasis on
     those bonds in the Trust's portfolio, and by the use of leverage to fund
     the purchases of additional portfolio investments. As high-yield bonds
     performed well, the use of leverage provided an opportunity for us to
     amplify the Trust's return. Historically, the Trust has employed leverage
     through the issuance of auction market preferred shares (AMPS). During the
     12-month period, the Trust redeemed all of its outstanding AMPS. The Trust
     continues to employ leverage through a margin loan financing agreement**.

     The Trust's results were also helped by the portfolio's exposures to
     investments in other securities, in addition to high-yield corporate bonds.
     These included catastrophe-linked bonds issued by insurance companies
     (which benefited from a mild hurricane season in 2013) and convertible
     securities, which tend to do well when stock prices rise, as they did
     throughout the Trust's fiscal year. To be sure, rising Treasury interest
     rates did act as a limit on overall fixed-income performance, including the
     performance of the Trust. However, the effect of rising Treasury rates on
     performance was buffered somewhat by our decision to keep the Trust's
     duration relatively short. (Duration is a measure of a Portfolio's price
     sensitivity to changes in interest rates.) At the end of the Trust's fiscal
     year, on March 31, 2014, the effective duration of the investments in the
     Trust's portfolio was 2.55 years, while the duration of the benchmark BofA
     ML High Yield Master II Index was 4.1 years.

     Investments in high-yield bonds issued by companies in basic industries
     such as chemicals and industrials did very well and aided the Trust's
     performance during the period. Energy sector bonds represented the largest
     component of the Trust's high-yield bond allocation, and while those
     securities underperformed during the period, we still increased the

**   Margin Loan Financing Agreement. See Notes to Financial Statements -- Note
     12.

6 Pioneer High Income Trust | Annual Report | 3/31/14


     portfolio's allocation to energy because of the industry's future earnings
     prospects, which we believe were enhanced during the period by improved
     commodity recovery rates at well sites, rising natural gas prices, and
     stabilizing oil prices.

     Individual securities that helped support the Trust's performance during
     the 12-month period included the convertible securities issued by Time
     Warner Telecom, which appreciated as the equity market rose, and the
     convertibles of Meritor, a commercial vehicle parts manufacturer which
     performed well as the automobile industry continued to recover. Among
     individual high-yield bond investments in the Trust's portfolio, stand-out
     performers included securities issued by Xerium Technologies, a
     manufacturer of highly efficient rollers used in paper production, and by
     Ono Finance, a Spanish cable communications corporation that was acquired
     by Vodaphone.

     The Trust's exposure to emerging markets bonds did not help performance
     during the period. The Trust's cash position also tended to hold back
     performance during the period: cash accounted for 4.4% of the Trust's total
     managed assets as of March 31, 2014. Because cash earns very low yields,
     especially relative to high-yield corporate bonds, the cash investments in
     the Trust's portfolio limited potential yield. We would note, however, that
     the cash position gave us the ability to invest quickly and
     opportunistically during the summer of 2013 when some attractive high-yield
     bonds were selling at low prices in the wake of the bond market sell-off.

     Individual portfolio investments that disappointed during the 12-month
     period included bonds of two companies that ran into financial difficulties
     and defaulted on their debt: Rural/Metro, an ambulance service provider;
     and Green Field Energy Services, an energy exploration and production
     services company that lost a major contract. Another poor-performing
     holding in the Trust's portfolio was the bond of Midwest Vanadium, an
     Australian miner of vanadium, which is a mineral used in the steel
     processing industry.

Q    How did the level of leverage in the Trust change during the 12-month
     period ended March 31, 2014?

A    At the end of the 12-month period, 27.1% of the Trust's total managed
     assets were financed by leverage, compared with 27.2% of the Trust's total
     managed assets financed by leverage at the start of the period on April 1,
     2013. The decrease was due to an increase in the values of securities in
     which the Trust had invested.

     As noted previously, the Trust historically employed leverage through the
     issuance of AMPS. Between March 13, 2014 and March 18, 2014, the Trust
     redeemed all of its outstanding AMPS. The Trust refinanced the AMPS through
     a margin loan financing agreement. The percentage of the Trust's

                           Pioneer High Income Trust | Annual Report | 3/31/14 7


     total managed assets financed by leverage through the margin loan financing
     agreement is expected to be approximately the same as was previously
     financed through the issuance of AMPS. However, the actual amount of
     leverage employed by the Trust may change from time to time.

Q    What is the investment outlook?

A    We foresee improved growth trends in the U.S. as well as globally, which
     should be good for the performance of high-yield corporate bonds as well as
     credit-sensitive securities in general. The continuing economic recovery
     should help sustain profit growth, buttress corporate balance sheets and
     enable companies to meet their debt obligations. We think default rates
     should remain low by historical standards. In the future, however, we
     believe positive portfolio performance is likely to be even more dependent
     upon good security selection, rather than on broad asset allocation
     decisions. We think this may bode well for Pioneer's investment style, as
     we rely heavily on fundamental analysis of individual corporations and
     securities.

     After strong performance by corporate bonds for most of the past five
     years, the yield advantages of credit-sensitive securities are not as wide
     as they were earlier, and investors should recognize that this factor will
     affect performance. Moreover, as the normal turnover of Trust assets
     occurs, we are finding that newer portfolio holdings tend to pay lower
     yields than maturing holdings. This trend should not have an immediate
     impact on the distributions paid to shareholders. However, the current high
     dividend* paid by the Trust may be more difficult to maintain as time goes
     by, especially when interest rates increase and the Trust's borrowing costs
     go up.

Please refer to the Schedule of Investments on pages 13-40 for a full listing of
Trust securities.

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

The Trust may invest in securities of issuers that are in default or that are in
bankruptcy.

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

When interest rates rise, the prices of 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.

8 Pioneer High Income Trust | Annual Report | 3/31/14


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.

Historically, the Trust employed leverage through the issuance of preferred
shares. The Trust has redeemed all of its outstanding preferred shares. The
Trust continues to employ 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 the holders of common shares.

The Trust is required to maintain certain regulatory and rating agency asset
coverage requirements in connection with its outstanding preferred shares. In
order to maintain required asset coverage levels, the Trust may be required to
alter the composition of its investment portfolio or take other actions, such as
redeeming preferred shares with the proceeds from portfolio transactions, at
what might be inopportune times in the market. Such actions could reduce the net
earnings or returns to holders of the Trust's common shares over time.

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.

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

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

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

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

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

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

The Bank of America Merrill Lynch High Yield Master II 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.

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

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

     Level 2 -- other significant observable inputs (including quoted prices for
                similar securities, interest rates, prepayment speeds credit
                risks, etc.) Level 3 -- significant unobservable inputs
                (including the Trust's own assumptions in determining fair value
                of investments).

     Level 3 -- significant unobservable inputs (including the Trust's own
                assumptions in determining fair value of investments).

Generally, equity securities are categorized as Level 1, fixed income securities
and senior loans are categorized as Level 2, and securities valued using fair
value methods (other than prices supplied by independent pricing services) as
level 3. See Notes to Financial Statements -- Note 1A.

Notes to Financial Statements | 3/31/14

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
year. Actual results could differ from those estimates.

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

A.   Security Valuation

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

                          Pioneer High Income Trust | Annual Report | 3/31/14 47


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

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

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

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

     At March 31, 2014, three securities were valued using fair value methods
     (other than securities valued using prices supplied by independent pricing
     services or broker-dealers) representing 0.8% of net assets applicable to
     common shareowners. The value of these fair valued securities are
     $3,074,743.

     Discounts and premiums on debt securities are accreted or amortized,
     respectively, daily, into interest income on an effective yield to maturity
     basis with a corresponding increase or decrease in the cost basis of the
     security. Premiums and discounts related to certain mortgage-backed
     securities are amortized or accreted in proportion to the monthly paydowns.
     Interest income, including interest on income bearing cash accounts, is
     recorded on an accrual basis, net of unrecoverable foreign taxes withheld
     at the applicable country rates.

48 Pioneer High Income Trust | Annual Report | 3/31/14


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

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

B.   Foreign Currency Translation

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

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

C.   Forward Foreign Currency Contracts

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

D.   Federal Income Taxes

     It is the Trust's policy to comply with the requirements of the Internal
     Revenue Code applicable to regulated investment companies and to distribute
     all of its taxable income and net realized capital gains, if any, to its
     shareowners. Therefore, no federal income tax provision is required. As of
     March 31, 2014, the Trust did not accrue any interest or penalties with
     respect to uncertain tax positions, which if applicable, would be recorded
     as income tax expense in the Statement of Operations. Tax returns filed
     within the prior three years remain subject to examination by federal and
     state tax authorities.

                          Pioneer High Income Trust | Annual Report | 3/31/14 49


     The amount and character of income and capital gain distributions to
     shareowners are determined in accordance with federal income tax rules,
     which differ from U.S. generally accepted accounting principles.
     Distributions in excess of net investment income or net realized gains are
     temporary overdistributions for financial statement 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, 2013, the Trust reclassified $1,804,296
     to decrease undistributed net investment income, $1,804,294 to decrease net
     realized loss on investments, credit default swaps and foreign currency
     transactions and $2 to increase paid-in capital to reflect permanent
     book/tax differences. These adjustments have no impact on the net assets or
     results of operations.

     At March 31, 2014, the Trust was permitted to carryforward indefinitely
     $50,381 of short-term capital losses and $1,657,658 of long-term capital
     losses without limitation. Additionally, at March 31, 2014, the Trust had a
     net capital loss carryforward of $44,553,197 of which the following amounts
     will expire between 2018 and 2019 if not utilized: $42,435,787 in 2018 and
     $2,117,410 in 2019.

     The Trust elected to defer $288,512 of capital losses recognized between
     November 1, 2013 and March 31, 2014 to its fiscal year ending March 31,
     2015.

     The tax character of distributions paid to shareowners during the years
     ended March 31, 2014 and March 31, 2013 was as follows:



     ---------------------------------------------------------------------------
                                                           2014             2013
     ---------------------------------------------------------------------------
                                                               
     Distribution paid from:
     Ordinary income                               $47,243,790       $46,949,093

          Total                                                     $ (1,990,107)
     ===========================================================================


     The difference between book-basis and tax-basis unrealized appreciation is
     primarily attributable to the realization for tax purposes of unrealized
     gains on investments in passive foreign investment companies, the book/tax

50 Pioneer High Income Trust | Annual Report | 3/31/14


     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 other book/tax temporary differences.

E.   Risks

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

     Under normal market conditions, the Trust invests at least 80% of its
     assets in below investment grade (high-yield) debt securities, loans and
     preferred stocks. Because the Trust's investments are concentrated in
     high-yield securities, the Trust is subject to risks of such securities.
     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. 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.

F.   Repurchase Agreements

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

G.   Automatic Dividend Reinvestment Plan

     All common shareowners whose shares are registered in their own names
     automatically participate in the Automatic Dividend Reinvestment Plan (the
     Plan), under which participants receive all dividends and capital gain
     distributions (collectively, dividends) in full and fractional common
     shares of the Trust in lieu of cash. Shareowners may elect not to
     participate in the Plan. Shareowners not participating in the Plan receive
     all dividends and capital gain distributions in cash. Participation in the
     Plan is completely voluntary and may be terminated or resumed at any time
     without penalty by notifying American Stock Transfer & Trust Company, the
     agent for shareowners in

                          Pioneer High Income Trust | Annual Report | 3/31/14 51


     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 common shares
     of the Trust on terms that differ from the terms of the Plan.

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

H.   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.
     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

52 Pioneer High Income Trust | Annual Report | 3/31/14


     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.

     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, 2014 are listed in the
     Schedule of Investments. The average value of swap contracts open during
     the year ended March 31, 2014 was $79,423.

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

                          Pioneer High Income Trust | Annual Report | 3/31/14 53


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, 2014,
the net management fee was 0.60% of the Trust's average daily managed assets,
which was equivalent to 0.83% 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,
2014, $269,255 was payable to PIM related to management costs, administrative
costs and certain other services is included in "Due to affiliates" and
"Administration fee payable" on the Statement of Assets and Liabilities.

3. Transfer Agents

Pioneer Investment Management Shareholder Services, Inc. (PIMSS), a wholly owned
indirect subsidiary of UniCredit, through a sub-transfer agency agreement with
American Stock Transfer & Trust Company, provides substantially all transfer
agent and shareowner services related to the Trust's common shares at negotiated
rates. Deutsche Bank Trust Company Americas (Deutsche Bank) is the transfer
agent, registrar, dividend paying agent and auction agent with respect to the
Trust's Auction Market Preferred Shares (AMPS). The Trust pays Deutsche Bank an
annual fee, as is agreed to from time to time by the Trust and Deutsche Bank,
for providing such services.

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

realized as a result of uninvested cash balances are used to reduce a portion of

expenses were not reduced under such arrangement.

5. Forward Foreign Currency Contracts

                          Pioneer High Income Trust | Annual Report | 3/31/14 57


11. Dividends to Preferred Shareowners

Prior to the redemption of the Trust's AMPS (See Note 10.), dividends on Series
M7 and Series TH7 were cumulative at a rate which reset every seven days based
on the results of an auction. Since February 2008, the Trust's auctions related
to the AMPS failed. Accordingly, during the period, dividends were paid at the
maximum rate on the auction dates described in the prospectus for the AMPS.
Dividends on Series W28 were also cumulative at a rate that reset every 28 days
based on the results of an auction. The maximum rate for each 7-day series was
150% of the 7 day commercial paper rate. The maximum rate for the 28-day series
is 150% of the 30 day commercial paper rate. Dividend rates on AMPS ranged from
0.05% to 0.225% during the period from April 1, 2013 to the redemption of Series
W7 AMPS on March 13, 2014, Series TH7 on March 14, 2014 and Series M7 AMPS on
March 18, 2014.

12. Margin Loan Financing

Effective March 10, 2014, the Trust 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, 2014, the Trust had a borrowing outstanding under the margin
agreement totaling $151,000,000. The interest rate charged at March 31, 2014 was
0.9306%. The margin loan was established in conjunction with the redemption of
all of the Trust's auction market preferred shares (See Note 10). During the
term of the loan through March 31, 2014, the average daily balance was
$137,875,000 at a weighted average interest rate of 0.93372%. With respect to
the margin agreement, interest expense of $70,477 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 borrowings outstanding.

As of the date indicated below, the Trust's debt outstanding and asset coverage
were as follows:

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 of Pioneer
High Income Trust (the "Trust"), including the schedule of investments, as of
March 31, 2014, and the related statement of operations and cash flows for the
year then ended, the statement of changes in net assets for each of the two
years in the period then ended, and the financial highlights for each of the
five years in the period then ended. These financial statements and financial
highlights are the responsibility of the Trust's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. We were
not engaged to perform an audit of the Trust's internal control over financial
reporting. Our audits included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Trust's internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall
financial statement presentation. Our procedures included confirmation of
securities owned as of March 31, 2014, by correspondence with the custodian, and
brokers or by other appropriate auditing procedures where replies from brokers
were not received. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Pioneer High Income Trust at March 31, 2014, the results of its operations and
cash flows, changes in its net assets and financial highlights for the year then
ended, and the changes in its net assets for the two years in the period then
ended, and the financial highlights for each of the five years in the period
then ended, in conformity with U.S. generally accepted accounting principles.

Approval of Investment Advisory Agreement

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

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

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

Nature, Extent and Quality of Services

The Trustees considered the nature, extent and quality of the services that had
been provided by PIM to the Trust, taking into account the investment objective
and strategy of the Trust. The Trustees reviewed the terms of the investment
advisory agreement. The Trustees also reviewed PIM's investment approach for the
Trust and its research process. The Trustees considered the resources of PIM and
the personnel of PIM who provide investment management services to the Trust.
They also reviewed the amount of non-Trust assets managed by the portfolio
managers of the Trust. The Trustees considered the non-investment resources and
personnel of PIM involved in

62 Pioneer High Income Trust | Annual Report | 3/31/14


PIM's services to the Trust, including PIM's compliance and legal resources and
personnel. The Trustees noted the substantial attention and high priority given
by PIM's senior management to the Pioneer fund complex.

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

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

Performance of the Trust

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

Management Fee and Expenses

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

                          Pioneer High Income Trust | Annual Report | 3/31/14 63


The Trustees considered that the Trust's management fee (based on managed
assets) for the twelve months ended June 30, 2013 was in the first quintile
relative to the management fees paid by other funds in its Strategic Insight
peer group for the comparable period. The Trustees also considered that the
Trust's expense ratio (based on managed assets) for the twelve months ended June
30, 2013 was in the first quintile relative to its Strategic Insight peer group
for the comparable period.

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

Profitability

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

64 Pioneer High Income Trust | Annual Report | 3/31/14


Economies of Scale

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

Other Benefits

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

Conclusion

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

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

                  SECTION I - POLICY PURPOSE AND APPLICABILITY

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

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

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

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

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

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


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

N/A

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

The aggregate non-audit fees for the Trust and affiliates,
as previously defined, totaled approximately $17,781 in
2014 and $17,942 in 2013.

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

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

ITEM 5. AUDIT COMMITTEE OF LISTED REGISTRANTS

(a) If the registrant is a listed issuer as defined in Rule 10A-3
under the Exchange Act (17 CFR 240.10A-3), state whether
or not the registrant has a separately-designated standing

Section 3(a)(58)(B) of the Exchange Act (15 U.S.C. 78c(a)(58)(B)),
so state.

N/A

(b) If applicable, provide the disclosure required by Rule 10A-3(d)

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

                            VERSION DATED July, 2004

                                    Overview

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

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

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

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

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

                                       1


                             Proxy Voting Procedures

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

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

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

                                       2


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

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

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

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

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

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

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

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

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

                                       3


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

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

   Share-Blocking

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

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

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

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

       o   Retains a record of the vote cast;

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

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

                                       4


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

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

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

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

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

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

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

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

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

                                       5


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

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

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

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

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

   We will generally support these and similar management proposals:

       o    Corporate name change.

       o    A change of corporate headquarters.

       o    Stock exchange listing.

       o    Establishment of time and place of annual meeting.

       o    Adjournment or postponement of annual meeting.

       o    Acceptance/approval of financial statements.

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

       o    Approval of minutes and other formalities.

                                       6


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

       o    Amendments to authorized signatories.

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

       o    Acceptance of labor agreements.

       o    Appointment of internal auditors.

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

Auditors
     We normally vote for proposals to:

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

       o    Restore shareholder rights to ratify the auditors.

     We will normally oppose proposals that require companies to:

       o    Seek bids from other auditors.

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

       o    Indemnify auditors.

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

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

                                       7


     General Board Issues
     Pioneer will vote for:

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

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

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

       o    Election of an honorary director.

     We will vote against:

       o    Minimum stock ownership by directors.

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

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

       o    Requirements to provide two candidates for each board seat.

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

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

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

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

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

     We will also vote against:

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

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

                                       8


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

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

       o    Contested election of directors.

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

       o    Mandatory retirement policies.

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

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

     Pioneer will vote for:

       o    Cumulative voting.

       o    Increase ability for shareholders to call special meetings.

       o    Increase ability for shareholders to act by written consent.

       o    Restrictions on the ability to make greenmail payments.

       o    Submitting rights plans to shareholder vote.

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

       o    Opting out of the following state takeover statutes:

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

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

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

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

                                       9


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

     o Fair price provisions.

     o Authorization of shareholder rights plans.

     o Labor protection provisions.

     o Mandatory classified boards.

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

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

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

       o    Proposals that allow shareholders to nominate directors.

     We will vote against:

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

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

       o    Classes of shares with unequal voting rights.

       o    Supermajority vote requirements.

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

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

       o    Extension of advance notice requirements for shareholder proposals.

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

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

                                       10


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

     Pioneer will vote for:

       o    Changes in par value.

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

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

       o    Bond issuance.

       o    Increases in "ordinary" preferred stock.

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

       o    Cancellation of company treasury shares.

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

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

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

     o Number of shares currently available for issuance;

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

     o Proposed use of the additional shares; and

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

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

       o    Proposals to submit private placements to shareholder vote.

       o    Other financing plans.

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

                                      11


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

     Pioneer will vote for:

       o    401(k) benefit plans.

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

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

     o Amendments to performance plans to conform with OBRA;

     o Caps on annual grants or amendments of administrative features;

     o Adding performance goals; and

     o Cash or cash-and-stock bonus plans.

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

       o    Require that option repricings be submitted to shareholders.

       o    Require the expensing of stock-option awards.

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

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

                                       12


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

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

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

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

            A = Shares reserved for plan/amendment,

            B = Shares available under continuing plans,

            C = Shares granted but unexercised and

            D = Shares outstanding.

       o    The plan must not:

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

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

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

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

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

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

       o    All other employee stock purchase plans.

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

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

                                       13


     We will vote against:

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

       o    Elimination of stock option plans.

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

       o    Limits on executive and director pay.

       o    Stock in lieu of cash compensation for directors.

     Corporate Governance
     Pioneer will vote for:

       o    Confidential Voting.

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

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

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

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

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

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

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

     We will vote against:

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

       o    Limitations on stock ownership or voting rights.

       o    Reduction in share ownership disclosure guidelines.

                                       14


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

       o    Mergers and acquisitions.

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

       o    Debt restructurings.

       o    Conversion of securities.

       o    Issuance of shares to facilitate a merger.

       o    Private placements, warrants, convertible debentures.

       o    Proposals requiring management to inform shareholders of merger
            opportunities.

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

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

     Pioneer will vote for:

       o    Establishment of new classes or series of shares.

       o    Establishment of a master-feeder structure.

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

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

       o    Approval of new or amended advisory contracts.

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

       o    Authorization for, or increase in, preferred shares.

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

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

                                       15


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

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

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

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

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

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

                                       16

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

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

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.

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

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
