President's Letter

Dear Shareowner,

Through the first nine months of 2010, the U.S. economy moved forward on a slow
path to recovery. But with the memory of a deep recession still lingering,
businesses and consumers remained cautious about both investing and spending.
While business fundamentals showed signs of improvement, there was still a
reluctance to hire, and high unemployment remains a problem. Wary investors,
concerned about risk, gravitated towards cash and bonds. We remain generally
optimistic about the prospects for economic recovery, although it may occur
more slowly than many would like.

At Pioneer, we have long advocated the benefits of staying diversified and
investing for the long term. This strategy has generally performed well for
many investors. Bond markets certainly rewarded investors in the first nine
months of 2010. While the equity markets barely budged, equities at the end of
September 2010 were inexpensive relative to bonds, compared with historic
levels, and represented potentially good value for long-term investors.

Pioneer has not changed the basic approach to investing that we have used for
more than 80 years. We remain focused on company fundamentals and risk
management. Our investment process is based on careful research into individual
companies, quantitative analysis, and active portfolio management. This
three-pillared process, which we apply to each of our portfolios, is supported
by an integrated team approach and is designed to carefully balance risk and
reward. Our experienced professionals devote themselves to the careful research
needed to identify investment opportunities in markets around the world.

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. There is no single best strategy that works for
every investor.


2     Pioneer High Income Trust | Semiannual Report | 9/30/10


We invite you to learn more about Pioneer and our time-tested approach to
investing by consulting with your financial advisor or visiting us online at

you for investing with Pioneer.

Sincerely,


/s/ Daniel K. Kingsbury

Portfolio Management Discussion | 9/30/10

The six months ended September 30, 2010, was a period when investor confidence
was sometimes shaken by signs of some slowing in the pace of economic progress
in the United States and China, and evidence of debt problems in some European
nations. Overall sentiment remained positive, however, and investors continued
to seek out greater income during a time when government securities offered
very low yields. In the following interview, Andrew Feltus discusses the
factors that influenced the performance of Pioneer High Income Trust over the
six months ended September 30, 2010. Mr. Feltus is a member of Pioneer's
fixed-income team, which is responsible for the daily management of the Trust.

Q  How did  Pioneer  High  Income  Trust  perform  during the six  months  ended
   September 30, 2010?

A  Pioneer High Income Trust produced a total return of 8.01% at net asset value
   and 10.86% at market price during the six months  ended  September  30, 2010,
   with shares of the Trust selling at a 19.3% premium to net asset value at the
   end of the period.  During the same six-month period,  the Trust's benchmark,
   the Bank of America/Merrill Lynch High Yield Master II Index (BOFA ML Index),
   returned  6.62%.  Unlike the Trust,  the BofA ML Index is not  leveraged.  On
   September 30, 2010, the 30-day SEC yield on the Trust's shares was 10.06%.

Q  What were the  principal  factors  that  influenced  the Trust's  performance
   during the six months ended September 30, 2010?

A  Investor  fears about the  resilience of the economic  recovery began to grow
   early in the period.  First,  concerns arose because of new disclosures about
   the debt  problems  for Greece.  Those  concerns  abated,  however,  when the
   European Union acted,  offering new loan guarantees for the troubled nations.
   As the European debt situation appeared to stabilize, new worries arose about
   the global economic rebound,  as evidence pointed to slowing growth trends in
   both the United States and China.  Those  worries added to market  volatility
   during the summer months.

   Confidence began returning, however, on new evidence that the economic
   recovery was persisting, although at an often slower pace than had been
   expected. High-yield corporate bonds and other credit-sensitive securities
   rallied in the late summer on news that the U.S. Federal Reserve Board (the
   Fed) was prepared to initiate a second round of monetary easing through
   quantitative action intended to increase financial liquidity in the capital
   markets.


4     Pioneer High Income Trust | Semiannual Report | 9/30/10


   Over the six months ended September 30, 2010, the better-quality tiers of
   the high-yield market (especially BB-rated securities) outperformed lower-
   quality debt, such as C-rated securities. The rally received impetus as
   many institutional investors, such as mutual funds and insurance companies,
   reduced their positions in very high-quality, low-yielding sectors and
   sought the better yields offered by the higher-quality segments of the
   high-yield universe. Meanwhile, the overall credit quality of high-yield
   bonds appeared sound by historical standards. It appeared that the
   high-yield default rate for 2010 would be just 1%, the lowest rate since
   the 1970s.

   In that environment, the Trust's overweight positions in bonds of companies
   in economically sensitive groups, such as basic industries and capital
   goods, helped the Trust's performance significantly, as we were able to
   take advantage of Pioneer's strength in fundamental security-by-security
   analysis. The Trust's security selection was very successful over the
   six-month period, with holdings in the Trust's portfolio outperforming the
   high-yield market, generally. The Trust also held no securities that
   defaulted during the six months ended September 30, 2010.

   The Trust's performance also received a boost by its use of leverage. At
   the end of the six-month period, 28.3% of the Trust's total investment
   portfolio was leveraged. While the Trust's leverage rate was lower than it
   was at the start of the six-month period (as of April 1, 2010) the decline
   was principally the result of appreciation in the value of the Trust's
   invested assets.

Q  What were your  principal  investment  strategies  for the Trust over the six
   months ended September 30, 2010?

A  Our investments for the Trust focused on domestic high-yield  corporate bonds
   throughout the six months ended September 30, 2010, with special  emphasis on
   basic  industries.  At the end of the  period,  66.3%  of the  Trust's  total
   investment  portfolio was in U.S.  high-yield bonds, with another 9.5% of the
   Trust's  total  investment  portfolio  invested in domestic  investment-grade
   debt. The Trust had some exposure to emerging  market debt and  international
   high-yield bonds,  which together accounted for 17.6% of its total investment
   portfolio, but our primary focus remained on domestic high-yield securities.

Q  What  investments  had  a  particularly  noteworthy  impact  on  the  Trust's
   performance during the six months ended September 30, 2010?

A  The Trust owned a number of excellent  high-yield bond performers,  including
   the securities of several companies that were acquired by other  corporations
   and whose debt was retired at a profit to the Trust. The companies  included:
   Cellu  Tissue,  a  paper  products  corporation;  L1  Identity  Solutions,  a
   technology  corporation;  and Mariner Energy,  an oil and gas exploration and
   production company. Other solid performers in the Trust's portfolio


                   Pioneer High Income Trust | Semiannual Report | 9/30/10     5


   included Teck Resources, a mining company, and Univision, the
   Spanish-language broadcast network.

   Poorer performers in the Trust's portfolio included: Sitel, an operator of
   call centers that had disappointing growth; Greek dairy company Fage, whose
   securities suffered as an indirect victim of Greece's national debt
   problems; and Appleton Papers, a paper and pulp company that announced
   disappointing earnings results. The Trust's small position in convertible
   securities also was not helpful during the six-month period, as the group
   underperformed, despite their generally high yields and low prices. At the
   end of the period, 5.5% of the Trust's total investment portfolio was
   invested in convertibles.

Q  What is your investment outlook?

A  The  economy  appears  to be  continuing  to grow,  although  the pace of the
   expansion  clearly has slowed from the period of faster growth we saw in late
   2009 and early  2010.  While  corporate  profits  are  strong  and seem to be
   improving,  corporations appear reluctant to take on new investment projects,
   in part because of uncertainties over government regulatory and tax policies.

   High-yield bonds continue to appear attractive and we think that default
   rates may remain low by historical standards. The spreads, or yield
   advantages, of high-yield bonds compared with Treasuries appear near
   long-term averages. While we anticipate that Treasury interest rates
   eventually will start rising, we think the spreads offered by high-yield
   bonds should continue to make them attractive investments, even as Treasury
   rates rise.


Please refer to the Schedule of Investments on pages 11-34 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. Investments in the
Trust are subject to possible loss due to the financial failure 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 fair price at the times
when the Trust believes it is desirable to do so and their market price is
generally more volatile


6     Pioneer High Income Trust | Semiannual Report | 9/30/10



than that of more liquid securities. Illiquid securities are also more
difficult to value and investment of the Trust's assets in illiquid securities
may restrict the Trust's ability to take advantage of market opportunities.

The Trust uses leverage through the issuance of preferred shares. Leverage
creates significant risks, including the risk that the Trust's income or
capital appreciation will not be sufficient to cover the cost of leverage,
which may adversely affect the return for the holders of common shares. Since
February of 2008, regularly scheduled auctions for the Trust's preferred shares
have failed and preferred shareowners have not been able to sell their shares
at auction. The Board of Trustees of the Trust has considered, and continues to
consider, this issue.

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.

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 the opinion of Trust management 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 www.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 net asset value (NAV), due to such factors as
interest rate changes and the perceived credit quality of borrowers.

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

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

Index comparison begins April 30, 2002. The Bank of America Merrill Lynch High
Yield Master II Index is a 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 is not leveraged. It is not possible to invest directly in
the Index.

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 seek capital
appreciation to the extent that it is consistent with its investment objective.

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 from time to time. Please refer to those documents
when considering the Trust's risks. At times, the Trust's investments may
represent industries or industry sectors that are interrelated or have common
risks, making it more susceptible to any economic, political, or regulatory
developments or other risks affecting those industries or 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 will be concentrated in the high-yield
securities, it will be 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.

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.


40     Pioneer High Income Trust | Semiannual Report | 9/30/10


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. The net asset value of
   the Trust is computed once daily, on each day the New York Stock Exchange
   (NYSE) is open, as of the close of regular trading on the NYSE. Investments
   in loan interests are valued in accordance with guidelines established by the
   Board of Trustees at the mean between the last available bid and asked prices
   from one or more brokers or dealers as obtained from Loan Pricing
   Corporation. For the limited number of loan interests for which no reliable
   price quotes are available, such loan interests will be valued by Loan
   Pricing Corporation through the use of pricing matrices to determine
   valuations. Fixed income securities with remaining maturity 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 are valued at the last sale price on the principal exchange
   where they are traded. Securities or loans for which market prices and/or
   quotations are not readily available or are considered to be unreliable are
   valued using fair value methods pursuant to procedures adopted by the Board
   of Trustees.

   The Trust may use the 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. Thus, the valuation of the Trust's securities may differ from
   exchange prices. At September 30, 2010, ten securities were valued using fair
   value methods (in addition to securities valued using prices supplied by
   independent pricing services) representing 1.3% of net assets applicable to
   common shareowners. Inputs used in the valuation of a security using fair
   value methods include credit ratings, the financial condition of the company,
   current market conditions and comparable securities. Short-term income
   securities with remaining maturities of sixty days or less generally are
   valued at amortized cost. Money market mutual funds are valued at net asset
   value.

   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 income on interest bearing cash accounts, is
   recorded on an accrual basis, net of unrecoverable foreign taxes withheld at
   the applicable country rates.


                  Pioneer High Income Trust | Semiannual Report | 9/30/10     41


   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 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 gains or losses are recorded in
   the Trust's financial statements. The Trust records realized gains and losses
   at the time a portfolio hedge 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. Tax
   years for the prior three fiscal years remain subject to examination by tax
   authorities.

   The amounts and characterizations of distributions to shareowners for
   financial reporting purposes are determined in accordance with federal income
   tax rules. Therefore, the sources of the Trust's distributions may be shown
   in the accompanying financial statements as either from or in excess


42     Pioneer High Income Trust | Semiannual Report | 9/30/10


   of net investment income or net realized gain (loss) on investment and
   foreign currency transactions, or from paid-in capital, depending on the type
   of book/tax differences that may exist.

   The tax character of current year distributions paid to common and preferred
   shareowners will be determined at the end of the fiscal year. Distributions
   paid during the year ended March 31, 2010 were as follows:




-------------------------------------------------
                                             2010
-------------------------------------------------
                                  
Distribution paid from:
Ordinary Income                       $45,923,054
-------------------------------------------------
   Total taxable distribution         $45,923,054
=================================================



  The following shows components of distributable earnings (losses) on a
  federal income tax basis at March 31, 2010.




---------------------------------------------------
                                               2010
---------------------------------------------------
                                  
Distributable earnings:
Undistributed ordinary income        $  13,299,905
Capital loss carryforward              (56,023,174)
Post-October loss deferred              (6,519,449)
Dividends payable                           (7,091)
Unrealized appreciation                 22,373,595
---------------------------------------------------
   Total                             $ (26,876,214)
===================================================



   The difference between book-basis and tax-basis unrealized appreciation is
   primarily attributable to the tax deferral of losses on straddles and wash
   sales, the realization for tax purposes of unrealized gains on certain
   foreign currency contracts, the difference between book and tax amortization
   methods for premiums and discounts on fixed income securities, the accrual of
   income on securities in default, and other book/tax temporary differences.


E. 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 sub custodians of the Trust. The Trust's
   investment adviser, Pioneer Investment Management, Inc. (PIM), is responsible
   for determining that the value of the collateral remains at least equal to
   the repurchase price.


F. Securities Lending

   The Trust lends securities in its portfolio to certain broker-dealers or
   other institutional investors. When entering into a securities loan
   transaction, the Trust typically receives cash collateral from the borrower
   equal to at least the


                  Pioneer High Income Trust | Semiannual Report | 9/30/10     43


   value of the securities loaned, which is invested in temporary investments.
   Credit Suisse AG, New York Branch, as the Trust's securities lending agent,
   manages the Trust's securities lending collateral. The income earned on the
   investment of collateral is shared with the borrower and the lending agent in
   payment of any rebate due to the borrower with respect to the securities
   loan, and in compensation for the lending agent's services to the Trust. The
   Trust also continues to receive payments in lieu of dividends or interest on
   the securities loaned. Gain or loss on the fair value of the loaned
   securities that may occur during the term of the loan will be for the account
   of the Trust. The amount of the collateral is required to be adjusted daily
   to reflect any price fluctuation in the value of the loaned securities. If
   the required market value of the collateral is less than the fair value of
   the loaned securities, the borrower is required to deliver additional
   collateral for the account of the Trust prior to the close of the next
   business day. The Trust has the right, under the lending agreement, to
   terminate the loan and recover the securities from the borrower with prior
   notice. The Trust is required to return the cash collateral to the borrower
   and could suffer a loss if the value of the collateral, as invested, has
   declined.


G. Automatic Dividend Reinvestment Plan

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

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


44     Pioneer High Income Trust | Semiannual Report | 9/30/10


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


2. Management Agreement

PIM, a wholly owned indirect subsidiary of UniCredit S.p.A. (UniCredit) manages
the Trust's portfolio. Management fees payable under the Trust's Advisory
Agreement with PIM are calculated daily at the annual rate of 0.60% of the
Trust's average daily managed assets. "Managed assets" means (a) the total
assets of the Trust, including any form of investment leverage, minus (b) all
accrued liabilities incurred in the normal course of operations, which shall not
include any liabilities or obligations attributable to investment leverage
obtained through (i) indebtedness of any type (including, without limitation,
borrowing through a credit facility of the issuance of debt securities), (ii)
the issuance of preferred stock or other similar preference securities, and/or
(iii) any other means. For the six months ended September 30, 2010, the net
management fee of 0.60% of the Trust's average daily managed assets, was
equivalent to 0.85% of the Trust's average daily net assets attributable to the
common shareowners.

In addition, under PIM's management and administration agreements, certain other
services and costs are paid by PIM and reimbursed by the Trust. At September 30,
2010 $269,166 was payable to PIM related to management costs, administrative
costs and certain other services and is in included in "Due to affiliates" on
the Statement of Assets and Liabilities.

Effective September 1, 2010 PIM has retained State Street Bank and Trust Company
(State Street) to provide certain administrative and accounting services to the
Trust on its behalf. For administrative services, PIM pays State


                  Pioneer High Income Trust | Semiannual Report | 9/30/10     45


Street a monthly fee at an annual rate of 0.07% of the Trust's managed assets up
to $500 million and 0.03% for managed assets in excess of $500 million, subject
to a minimum monthly fee of $10,000. Previously, PIM had retained Princeton
Administrators, LLC (Princeton) to provide such services. PIM paid Princeton a
monthly fee at an annual rate of 0.07% of the Trust's average daily managed
assets up to $500 million and 0.03% for average daily managed assets in excess
of $500 million, subject to a minimum monthly fee of $10,000. Neither State
Street nor Princeton received compensation directly from the Trust for providing
such services.


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.


4. Expense Offset Arrangements

The Trust has entered into an arrangement with its custodian whereby credits
realized as a result of uninvested cash balances are used to reduce a portion of
the Trust's custodian expenses. For the six months ended September 30, 2010, the
Trust expenses were reduced by $1 under such arrangement.


5. Forward Foreign Currency Contracts

During the six months ended September 30, 2010, the Trust entered into various
forward foreign currency contracts that obligate the Trust to deliver or take
delivery of currencies at specified future maturity dates. Alternatively, prior
to the settlement date of a forward foreign currency contract, the Trust may
close out such contract by entering into an offsetting contract. The average
number of contracts open during the six months ended September 30, 2010 was
5,572,167.

As of September 30, 2010, the Trust had no outstanding forward currency
settlement contracts.

7. Trust Shares

There are an unlimited number of common shares of beneficial interest
authorized.

Transactions in common shares of beneficial interest for the six months ended
September 30, 2010 and the year ended March 31, 2010 were as follows:




------------------------------------------------------------------------
                                                    9/10            3/10
------------------------------------------------------------------------
                                                        
Shares outstanding at beginning of period     27,737,499      27,463,925
Reinvestment of distributions                    132,539         273,574
------------------------------------------------------------------------
Shares outstanding at end of period           27,870,038      27,737,499
========================================================================



The Trust may classify or reclassify any unissued common shares of beneficial
interest into one or more series of preferred shares of beneficial interest. As
of September 30, 2010, there were 6,040 AMPS as follows: Series M7-2,020, Series
W28-2,020 and Series TH7-2,000.

Dividends on Series M7 and Series TH7 are cumulative at a rate which is reset
every seven days based on the results of an auction. Dividends on Series W28 are
also cumulative at a rate reset every 28 days based on the results of an
auction. An auction fails if there are more AMPS offered for sale than there are
buyers. When an auction fails, the dividend rate for the period will be the
maximum rate on the auction dates described in the prospectus for the AMPS.
Preferred shareowners will not be able to sell their AMPS at an auction if the
auction fails. Since February 2008, the Trust's auctions related to the AMPS
have failed. The maximum rate for the 7-Day Series is 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 0.135% to 0.542%
during the six months ended September 30, 2010.

The Trust may not declare dividends or make other distributions on its common
shares or purchase any such shares if, at the time of the declaration,
distribution or purchase, the Trust does not comply with the asset coverage
ratios described in the prospectus for the AMPS.


                  Pioneer High Income Trust | Semiannual Report | 9/30/10     47


The AMPS are redeemable at the option of the Trust, in whole or in part, on any
dividend payment date at $25,000 per share plus any accumulated or unpaid
dividends, whether or not declared. The AMPS are also subject to mandatory
redemption at $25,000 per share plus any accumulated or unpaid dividends,
whether or not declared, if certain requirements relating to the composition of
the assets and liabilities of the Trust as set forth in the Statement of
Preference are not satisfied.

The holders of AMPS have voting rights equal to the holders of the Trust's
common shares (one vote per share) and will vote together with holders of the
common shares as a single class. Holders of AMPS are also entitled to elect two
of the Trust's Trustees. In addition, the Investment Company Act of 1940, as
amended, requires that along with approval by shareowners that might otherwise
be required, the approval of the holders of a majority of any outstanding
preferred shares, voting separately as a class, would be required to (a) adopt
any plan of reorganization that would adversely affect the preferred shares and
(b) take any action requiring a vote of security holders, including, among other
things, changes in the Trust's subclassification as a closed-end management
investment company or changes in its fundamental investment restrictions.

shares totaled $58,204 in aggregate for the two outstanding preferred share
series through November 24, 2010.

(a) Disclose whether, as of the end of the period covered by the report, the
registrant has adopted a code of ethics that applies to the registrant's
principal executive officer, principal financial officer, principal accounting
officer or controller, or persons performing similar functions, regardless of
whether these individuals are employed by the registrant or a third party.  If
the registrant has not adopted such a code of ethics, explain why it has not

that are reasonably designed to deter wrongdoing and to promote:

        (1) Honest and ethical conduct, including the ethical handling of actual
        or apparent conflicts of interest between personal and professional
        relationships;

        (2) Full, fair, accurate, timely, and understandable disclosure in
        reports and documents that a registrant files with, or submits to, the
        Commission and in other public communications made by the registrant;

period covered by the report, to a provision of its code of ethics that applies
to the registrant's principal executive officer, principal financial officer,
principal accounting officer or controller, or persons performing similar
functions, regardless of whether these individuals are employed by the
registrant or a third party, and that relates to any element of the code of
ethics definition enumerated in paragraph (b) of this Item. The registrant must
file a copy of any such amendment as an exhibit pursuant to Item 10(a), unless

financial expert.

 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.

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

                            VERSION DATED July, 2004

                                    Overview

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

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

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

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

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

                             Proxy Voting Procedures

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

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

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

                                       2


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

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

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

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

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

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

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

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

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

                                       3


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

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

   Share-Blocking

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

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

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

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

       o   Retains a record of the vote cast;

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

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

                                       4


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

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

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

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

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

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

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

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

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

                                       5


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

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

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

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

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

   We will generally support these and similar management proposals:

       o    Corporate name change.

       o    A change of corporate headquarters.

       o    Stock exchange listing.

       o    Establishment of time and place of annual meeting.

       o    Adjournment or postponement of annual meeting.

       o    Acceptance/approval of financial statements.

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

       o    Approval of minutes and other formalities.

                                       6


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

       o    Amendments to authorized signatories.

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

       o    Acceptance of labor agreements.

       o    Appointment of internal auditors.

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

Auditors
     We normally vote for proposals to:

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

       o    Restore shareholder rights to ratify the auditors.

     We will normally oppose proposals that require companies to:

       o    Seek bids from other auditors.

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

       o    Indemnify auditors.

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

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

                                       7


     General Board Issues
     Pioneer will vote for:

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

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

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

       o    Election of an honorary director.

     We will vote against:

       o    Minimum stock ownership by directors.

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

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

       o    Requirements to provide two candidates for each board seat.

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

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

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

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

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

     We will also vote against:

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

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

                                       8


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

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

       o    Contested election of directors.

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

       o    Mandatory retirement policies.

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

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

     Pioneer will vote for:

       o    Cumulative voting.

       o    Increase ability for shareholders to call special meetings.

       o    Increase ability for shareholders to act by written consent.

       o    Restrictions on the ability to make greenmail payments.

       o    Submitting rights plans to shareholder vote.

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

       o    Opting out of the following state takeover statutes:

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

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

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

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

                                       9


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

     o Fair price provisions.

     o Authorization of shareholder rights plans.

     o Labor protection provisions.

     o Mandatory classified boards.

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

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

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

       o    Proposals that allow shareholders to nominate directors.

     We will vote against:

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

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

       o    Classes of shares with unequal voting rights.

       o    Supermajority vote requirements.

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

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

       o    Extension of advance notice requirements for shareholder proposals.

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

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

                                       10


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

     Pioneer will vote for:

       o    Changes in par value.

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

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

       o    Bond issuance.

       o    Increases in "ordinary" preferred stock.

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

       o    Cancellation of company treasury shares.

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

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

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

     o Number of shares currently available for issuance;

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

     o Proposed use of the additional shares; and

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

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

       o    Proposals to submit private placements to shareholder vote.

       o    Other financing plans.

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

                                      11


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

     Pioneer will vote for:

       o    401(k) benefit plans.

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

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

     o Amendments to performance plans to conform with OBRA;

     o Caps on annual grants or amendments of administrative features;

     o Adding performance goals; and

     o Cash or cash-and-stock bonus plans.

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

       o    Require that option repricings be submitted to shareholders.

       o    Require the expensing of stock-option awards.

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

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

                                       12


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

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

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

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

            A = Shares reserved for plan/amendment,

            B = Shares available under continuing plans,

            C = Shares granted but unexercised and

            D = Shares outstanding.

       o    The plan must not:

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

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

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

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

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

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

       o    All other employee stock purchase plans.

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

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

                                       13


     We will vote against:

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

       o    Elimination of stock option plans.

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

       o    Limits on executive and director pay.

       o    Stock in lieu of cash compensation for directors.

     Corporate Governance
     Pioneer will vote for:

       o    Confidential Voting.

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

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

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

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

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

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

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

     We will vote against:

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

       o    Limitations on stock ownership or voting rights.

       o    Reduction in share ownership disclosure guidelines.

                                       14


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

       o    Mergers and acquisitions.

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

       o    Debt restructurings.

       o    Conversion of securities.

       o    Issuance of shares to facilitate a merger.

       o    Private placements, warrants, convertible debentures.

       o    Proposals requiring management to inform shareholders of merger
            opportunities.

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

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

     Pioneer will vote for:

       o    Establishment of new classes or series of shares.

       o    Establishment of a master-feeder structure.

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

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

       o    Approval of new or amended advisory contracts.

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

       o    Authorization for, or increase in, preferred shares.

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

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

                                       15


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

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

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

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

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

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

                                       16


Item 8. Portfolio Managers of Closed-End Management Investment
        Companies.

(a) If the registrant is a closed-end management investment company that
is filing an annual report on this Form N-CSR,provide the following
information:
(1) State the name, title, and length of service of the person or persons
employed by or associated with the registrant or an investment adviser
of the registrant who are primarily responsible for the day-to-day management
of the registrants portfolio (Portfolio Manager). Also state each Portfolio
Managers business experience during the past 5 years.

Additional Information About the Portfolio Managers

Other Accounts Managed by the Portfolio Managers. The table below indicates, for
the portfolio manager of the fund, information about the accounts other than the
fund over which the portfolio manager has day-to-day investment responsibility.
All information on the number of accounts and total assets in the table is as of
March 31, 2010. For purposes of the table, "Other Pooled Investment Vehicles"
may include investment partnerships, undertakings for collective investments in
transferable securities ("UCITS") and other non-U.S. investment funds and group
trusts, and "Other Accounts" may include separate accounts for institutions or
individuals, insurance company general or separate accounts, pension funds and
other similar institutional accounts but generally do not include the portfolio
manager's personal investment accounts or those which the manager may be deemed
to own beneficially under the code of ethics. Certain funds and other accounts
managed by the portfolio manager may have substantially similar investment
strategies.

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
          basis.  Although  Pioneer  believes that its practices are  reasonably
          designed to treat each client in an equitable  and fair manner,  there
          may be instances where a fund may not participate,  or may participate
          to a  lesser  degree  than  other  clients,  in the  allocation  of an
          investment opportunity.

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

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

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

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



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

     o    Quantitative  Investment  Performance.   The  quantitative  investment
          performance  calculation is based on pre-tax investment performance of
          all of the accounts  managed by the portfolio  manager (which includes
          the fund and any other accounts managed by the portfolio manager) over
          a  one-year   period  (20%   weighting)  and  four-year   period  (80%
          weighting),  measured for periods ending on December 31. The accounts,
          which  include the fund,  are ranked  against a group of mutual  funds
          with similar  investment  objectives and investment  focus (60%) and a
          broad-based  securities  market index measuring the performance of the
          same type of securities in which the accounts invest (40%),  which, in
          the case of the fund, is the 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 may participate in other programs designed to reward
and retain key contributors. Senior executives or other key employees may be
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.

of Schedule 14A (17 CFR 240.14a-101), or this Item.


There have been no material changes to the procedures by which the
shareholders may recommend nominees to the registrants board of
directors since the registrant last provided disclosure in response
to the requirements of Item 7(d)(2)(ii)(G) of Schedule 14(A) in
its definitive proxy statement, or this Item.


ITEM 11. CONTROLS AND PROCEDURES.

(a) Disclose the conclusions of the registrant's principal executive officer or
officers and principal financial officer or officers, or persons performing
similar functions, about the effectiveness of the registrant's disclosure
controls and procedures (as defined in Rule 30a-2(c) under the Act (17 CFR
270.30a-2(c))) based on their evaluation of these controls and procedures as of
a date within 90 days of the filing date of the report that includes the
disclosure required by this paragraph.

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


(b) Disclose whether or not there were significant changes in the registrant's
internal controls or in other factors that could significantly affect these
controls subsequent to the date of their evaluation, including any corrective
actions with regard to significant deficiencies and material weaknesses.

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

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

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


ITEM 12. EXHIBITS.

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

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



(b) A separate certification for each principal executive officer and principal
financial officer of the registrant as required by Rule 30a-2 under the Act
(17 CFR 270.30a-2).

Filed herewith.
