Dear Shareowner,
--------------------------------------------------------------------------------
There's a conundrum seen when observing the U.S. economy. In spite of sky high
oil prices and real estate prices starting to soften, the U.S. economy was on a
tear in the first quarter of 2006. Sizzling, roaring, and surging are terms used
recently in headlines to describe the current state of our economy.

Our nation's gross domestic product (GDP), the broadest measure of the economy's
strength, rose at an annual rate of 4.8% in the first quarter, the fastest
growth rate since the third quarter of 2003. Part of this growth is a rebound
from a soft fourth quarter, but there is also real underlying growth. Business
spending is up 14.3% as the caution of previous years is being overcome by the
need for equipment and technology. Consumers are doing their part by pushing the
sales of consumer durables up 20.6% through the purchase of new household goods
and luxury items.

It is difficult to project how long this growth will last, but most economists
tend to agree that it can do so as long as business and consumer demand
continues and inflation remains low.

Foreign markets are also faring well, benefiting from growth-oriented economic
policies, and world economic growth is becoming more broadly based. The Japanese
economy is expanding, and there are signs of a sustained recovery in Europe.
Growth in the emerging economies and developing nations remains solid, with
tremendous strength in China, India and Russia. Looking forward, we expect
strong growth to continue, yet we remain cautious.

Investor confidence, a favorable economic climate and healthy corporate
profitability and cash flow have helped global stock markets continue their
strong performance in 2006.

The broad U.S. stock market is doing extremely well thus far in 2006. Investors
seem to have grown accustomed to companies generally delivering on their
earnings promises, lessening anxiety in the marketplace. Investors are feeling
confident with stocks, especially those of mid-sized and small companies, which
have far outpaced large-cap stocks.

Letter

Yet, the Federal Reserve response to the strong economy in the first quarter has
been cautious, weighing whether further interest hikes are necessary. This
concerns some in the financial markets, who have grown accustomed to the Fed
confidently determining the movement of rates in the past.

The Treasury-bond market ended the first quarter with short- and long-term bond
yields almost equal - a flat yield curve. Although municipal-bond yields are not
quite flat, the difference between short- and long-term interest rates is the
smallest it has been since 1989. Even if the Fed's interest rate hikes end soon,
intermediate and long interest rates are still low relative to inflation.

In summary, the economy and financial markets in the U.S. are prospering and the
fundamentals remain, in our view, healthy going forward. However, there are no
guarantees in investing: we know from a long-view of history that sudden shifts
can occur with little warning. We need only look to the natural disasters and
political upheavals of 2005. As such, we continue to pursue our philosophy in
stock and bond portfolio management: global resources dedicated to fundamental
research in the pursuit of opportunities that offer an attractive balance of
risk and reward to help our shareowners grow their assets.

Respectfully,

/s/ Osbert M. Hood

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 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 market price.

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

Index comparison begins April 30, 2002. The 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. You cannot invest directly in an Index.

PORTFOLIO MANAGEMENT DISCUSSION 3/31/06
--------------------------------------------------------------------------------

High yield corporate bonds performed well during the 12 months ended March 31,
2006, despite suffering some price erosion as interest rates rose among
virtually all parts of the fixed-income market. In general, balance sheets of
high-yield issuers improved as corporate profits rose in a steadily growing
economy. The following is an interview with Kenneth J. Taubes and Andrew Feltus,
who discuss the performance of High Income Trust during the 12 months. Mr.
Taubes is director of Pioneer's Fixed Income Group, and Mr. Feltus is a member
of the team responsible for the daily management of the Trust.

Q: How did the Trust perform?

A: The Fund performed very well based on its net asset value and had extremely
   strong results based on market price. For the 12 months ended March 31, 2006,
   the Trust had a total return of 10.91% at net asset value, outperforming the
   benchmark Merrill Lynch High Yield Master II, which returned 7.23%. The
   Trust's return at market price was 24.84%, as the price of the Trust's shares
   went from a 7.5% discount to a 4.2% premium price over net asset value. The
   Trust also continued to produce a generous flow of dividend income. On March
   31, 2006, the Trust's current SEC 30-day yield was 11.22%.

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

   The performance data quoted represents past performance, which is no
   guarantee of future results. Investment return and principal value will
   fluctuate, and shares, when redeemed, may be worth more or less than their
   original cost.

Q: What was the environment like during the 12 months?

A: Domestic high-yield bonds, which constitute our primary focus, performed well
   as the economy continued to grow and corporate profits remained strong. While
   interest rates rose in virtually all segments of the fixed-income markets,
   high-yield bonds generated strong relative performance, suffering less price
   loss than Treasuries and other high-grade securities. At the start of the
   fiscal year, spreads - which reflect the yield differences between high-grade
   and high-yield securities - were relatively tight, implying that investors
   saw relatively little risk in high-yield bonds. That situation

                                                                               7

PORTFOLIO MANAGEMENT DISCUSSION 3/31/06                            (continued)
--------------------------------------------------------------------------------

   changed abruptly in the spring of 2005 when the high-yield market slumped as
   evidence accumulated about the mounting financial problems of automotive
   leaders General Motors and Ford. The credit ratings of securities of both
   companies eventually were downgraded from investment-grade to
   below-investment-grade. The high-yield market recovered during the summer
   months, but then fell again in the fall as the overall fixed-income market
   slumped as interest rates rose and bond prices declined. While all fixed-
   income securities felt the effects of this volatility, the high-yield market
   suffered more than many other classes as investors grew increasingly cautious
   about credit risk. Adding to the unease was the approach of a new federal
   bankruptcy law, which led to the bankruptcy filings of several companies,
   including automotive parts manufacturer Delphi and airlines Northwest and
   Delta. However, this slump ended in late 2005, and the high-yield market
   rallied during the final five months of the fiscal year, helped by the
   expectation that the Federal Reserve Board was nearing the end of its round
   of interest-rate hikes. In addition, the expectation that General Motors
   would sell a majority stake in its financing unit, GMAC, helped the
   high-yield market. The fiscal year ended with yield differentials again
   tight, with high-yield bonds offering relatively little yield advantage when
   judged by historical standards.

Q: What were your principal strategies in this environment?

A: The major change we made to the portfolio during the fiscal year was to
   upgrade overall quality as the gaps between yields of different quality bonds
   tightened, and lower-rated bonds offered less yield advantage. We lowered
   duration - or sensitivity to changes in interest rates - and focused on
   higher-rated bonds within the high-yield universe. At the end of the fiscal
   year, on March 31, 2006, the Trust's average effective duration was 3.75
   years, down from the 4.55 years six months earlier and substantially lower
   than the 4.41 years of the Merrill Lynch sector index.

   While the high-yield bond market by its nature has a heavy representation of
   cyclical companies whose fortunes depend on the business cycle, we did reduce
   our exposure to highly cyclical companies and focused more on companies with
   greater earnings consistency, such as in the health care and consumer
   sectors.

Pioneer High Income Trust
--------------------------------------------------------------------------------

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

   At the end of the fiscal year, domestic high-yield bonds accounted for 72.9%
   of Trust assets.

   At the end of the fiscal year, slightly less than 25% of Trust assets were
   leveraged. The Trust has the ability to use leverage and borrow up to 33% of
   assets at short-term rates to invest in high-yield bonds. The ability to use
   leverage helped contribute to performance.

Q: What types of investments had the greatest influence on performance, either
   positively or negatively?

A: Our heavy position in the transportation industry was a major factor in the
   Trust's strong results. Bonds backed by Continental Airlines, U.S. Airways
   and AMR, parent company of American Airlines all did very well, although we
   had a small position in Northwest Airline bonds. That position detracted from
   results when the company filed for bankruptcy protection.

   Also helping performance was our decision to maintain only a small exposure
   to the automotive industry, which performed very poorly. Within our small
   positions, we did have good results from truck manufacturers, which we
   emphasized. The manufacturers benefited from new federal regulations that
   increased the demand for trucks. We also had a position in Goodyear Tire that
   performed well. Bonds of auto parts manufacturer Tenneco likewise contributed
   to performance. However, another auto parts manufacturer, Delphi, filed for
   bankruptcy protection and hurt performance during the year.

   Another holding that detracted from results was Duane Reade, which operates
   pharmacies and convenience stores in the New York metropolitan area. However,
   it has brought in a new management team, and the bonds began showing improved
   performance late in the fiscal year, even though they were a drag on
   performance for the full 12 months.

Q: What is your investment outlook?

A: As we enter a new fiscal year, we find that valuations in the high-yield
   market are not as attractive as they were two or three years ago. However,

   issuers. In this environment, we believe the market has the potential to
   deliver decent returns. Shareowners also should be aware that if short-term
   interest rates continue to rise and add to the Trust's borrowing costs, the
   Trust's ability to sustain its level of dividends could be affected.

   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 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 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 may use leverage through the issuance of preferred shares with an
   aggregate liquidation preference of up to 25% of the Trust's total assets
   after such issuance. 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.

   Risks of investing in the Trust are discussed in greater detail in the
   Trust's registration statement on Form N-2 relating to its common shares.

NOTES TO FINANCIAL STATEMENTS 3/31/06
--------------------------------------------------------------------------------

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 25, 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 Trust invests in below investment grade (high-yield) debt securities, loans
and preferred stocks. Certain high-yield securities held by the Trust may be
convertible into equity securities of the issuer. Debt securities rated below
investment grade are commonly referred to as "junk bonds" and are considered
speculative. These securities involve greater risk of loss, are subject to
greater price volatility, and are less liquid, especially during periods of
economic uncertainty or change, than higher rated debt securities.

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, and the reported amounts of income,
expenses and gains and losses on investments during the reporting year. Actual
results could differ from those estimates.

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

A. Security Valuation

   Security transactions are recorded as of trade date. Fixed-income securities
   are valued at prices supplied by independent pricing services, which consider
   such factors as Treasury spreads, yields, maturities and ratings. Valuations
   may be supplemented by dealers and other sources, as required. Equity
   securities are valued at the last sales price on the principal exchanges
   where they are traded. Securities for which market quotations are not readily
   available are valued at their fair values as determined by, or under the
   direction of, the Board of Trustees. Trading in foreign securities is
   substantially completed each day at various times prior to the close of the
   NYSE. The values of such securities used in computing the net

30


Pioneer High Income Trust
--------------------------------------------------------------------------------

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

   asset value of the Trust's shares are determined as of such times. The Trust
   may also use the fair value of a security, including a non-U.S. security,
   when the closing market price on the primary exchange where the security is
   traded no longer accurately reflects the value of the security as of the
   close of the exchange. As of March 31, 2006, the Trust had no fair valued
   securities. Temporary cash investments are valued at amortized cost.

   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. Discount and premium on debt securities
   are accreted or amortized, respectively, daily, on an effective yield to
   maturity basis and are included in interest income. Premiums and discounts
   related to certain mortgage-backed securities are amortized or accreted in
   proportion to the underlying monthly paydowns. Interest income, including
   income on interest bearing cash accounts, is recorded on an accrual basis.

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

   The Trust's investments in 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.

   Information regarding the Trust's principal risks are contained in the
   Trust's prospectus, with additional information included in the Trust's
   Shareholder 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

                                                                              31

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

   "junk bonds" and are considered speculative with respect to the issuer's
   capacity to pay interest and repay principal.

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 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 price of those securities but are included with the net realized and
   unrealized gain or loss on investments.

C. Forward Foreign Currency Contracts

   The Trust enters into forward foreign currency contracts (contracts) for the
   purchase or sale of a specific foreign currency at a fixed price on a future
   date as a hedge or cross-hedge against either specific investment
   transactions (settlement hedges) or portfolio positions (portfolio hedges).
   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 contract and from unanticipated movements in the value of
   foreign currencies relative to the U.S. dollar (see Note 4).

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.

32


Pioneer High Income Trust
--------------------------------------------------------------------------------

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

   The amounts and characterizations of distributions to shareowners for
   financial reporting purposes are determined in accordance with federal income
   tax rules. Therefore, the source of the Trust's distributions may be shown in
   the accompanying financial statements as either from or in excess of net
   investment income or net realized gain on investment and foreign currency
   transactions, or from paid-in capital, depending on the type of book/tax
   differences that may exist.

   At March 31, 2006, the Trust reclassified $2,358,420 to increase
   undistributed net investment income and to decrease accumulated net realized
   gain on investments. The reclassification has no impact on the net asset
   value of the Trust and presents the Trust's capital accounts on a tax basis.

   The tax character of current year distributions paid to common and preferred
   shareowners during the years ended March 31, 2006 and March 31, 2005 was as
   follows:



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

  Distributions paid from:
  Ordinary Income                 $50,434,525      $48,778,440
  Net long-term capital gains       5,722,891        1,798,301

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



   The following shows components of distributable earnings on a federal income
   tax basis at March 31, 2006.



------------------------------------------------
                                 
  Undistributed ordinary income     $11,104,072
  Long-term capital gain              1,430,792
  Dividends payable                     (91,490)
  Unrealized appreciation            38,553,750

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


   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

                                                                              33

   discounts on fixed income securities and difference between book and tax in
   the accrual of income on securities in default.

E. Repurchase Agreements

   With respect to repurchase agreements entered into by the Trust, the value of
   the underlying securities (collateral), including accrued interest received
   from counterparties, is required to be at least equal to or in excess of the
   repurchase agreement at the time of purchase. The collateral for all
   repurchase agreements is held in safekeeping in the customer-only account of
   the Trust's custodian, or subcustodians. Pioneer Investment Management, Inc.
   ("PIM"), the Trust's investment adviser 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, with the Trust's custodian acting as the
   lending agent. When entering into a loan, the Trust receives collateral which
   is maintained by the custodian and earns income in the form of negotiated
   lenders' fees. The Trust also continues to receive interest or payments in
   lieu of dividends on the securities loaned. Unrealized 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 loans are secured by
   collateral of at least 102%, at all times, of the fair value of the
   securities loaned. The amount of the collateral will be adjusted daily to
   reflect any price fluctuation in the value of the loaned securities. The
   Trust has the right under the securities lending arrangement to recover the
   securities on loan from the borrower on demand. The Trust invests cash
   collateral in the Securities Lending Investment Fund which is sponsored by
   Brown Brothers Harriman & Co., the Trust's custodian.

G. Automatic Dividend Reinvestment Plan

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

2. Management Agreement

PIM, a wholly owned indirect subsidiary of Unicredito Italiano S.p.A.
("Unicredito Italiano") manages the Trust's portfolio. Management fees are
calculated weekly at the annual rate of 0.60% of the Trust's average weekly
managed assets. "Managed assets" is the average

PIM has retained Princeton Administrators, L.P., to provide certain
administrative services to the Trust on its behalf. PIM pays Princeton
Administrators, L.P., a monthly fee at an annual rate of 0.07% of the average
weekly value of the Trust's managed assets, subject to a minimum monthly fee of
$10,000. Princeton Administrators, L.P. receives no compensation directly from
the Trust.

3. Transfer Agents

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

4. Forward Foreign Currency Contracts

During the year ended March 31, 2006, the Trust had entered into contracts that
obligate the Trust to deliver currencies at specified future dates. At the
maturity of a contract, the Trust must make delivery of the foreign currency.
Alternatively, prior to the settlement date of contracts, the Trust may close
out such contracts by entering into an offsetting hedge contract.

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 March 31, 2006, there were 6,040 AMPS as follows: Series M7-2,020, Series
W28-2,020 and Series TH7-2,000.

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. Dividend rates ranged from 2.89% to 4.82% during the year ended March
31, 2006.

                                                                              37

NOTES TO FINANCIAL STATEMENTS 3/31/06                              (continued)

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, asset coverage with respect to the outstanding
preferred shares would be less than 200%.

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 Agreement and
Declaration of Trust 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. However, 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.

6. Subsequent Events

Subsequent to March 31, 2006, the Board of Trustees of the Trust declared a
dividend from undistributed net investment income of $0.1375 per common share
payable April 28, 2006, to shareowners of record on April 18, 2006.

For the period April 1, 2006 to April 30, 2006, dividends declared on preferred
shares totaled $549,021 in aggregate for the three outstanding preferred share
series.

--------------------------------------------------------------------------------
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
--------------------------------------------------------------------------------

To the Board of Trustees and the Shareowners of Pio neer High Income Trust:

We have audited the accompanying statement of assets and liabilities of Pioneer
High Income Trust (the "Trust"), including the schedule of investments, as of
March 31, 2006, and the related statement of operations for the year then ended,
the statements of changes in net assets for each of the two years in the period
then ended, and the financial highlights for each of the four years in the
period then ended. These financial statements and financial highlights are the
responsibility of the Trust's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. We were
not engaged to perform an audit of the Trust's internal control over financial
reporting. Our audits included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Trust's internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall
financial statement presentation. Our procedures included confirmation of
securities owned as of March 31, 2006, by correspondence with the custodian and
brokers or by other appropriate auditing procedures where replies from brokers
were not received. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Pioneer High Income Trust at March 31, 2006, the results of its operations for
the year then ended, the changes in its net assets for each of the two years in
the period then ended, and the financial highlights for each of the four years
in the period then ended, in conformity with U.S. generally accepted accounting
principles.

--------------------------------------------------------------------------------
FACTORS CONSIDERED BY THE INDEPENDENT TRUSTEES IN APPROVING THE MANAGEMENT
CONTRACT
--------------------------------------------------------------------------------

The Investment Company Act of 1940 requires that the Board of Trustees and a
majority of the Independent Trustees (collectively the "Trustees") voting
separately annually approve the Trust's Management Contract (the "Management
Contract"). The Trustees have determined that the terms of the Management
Contract are fair and reasonable and that renewal of the contract will enable
the Trust to receive quality investment advisory services at a cost deemed
reasonable and is in the best interests of the Trust and its shareowners. In
making such determinations, the Independent Trustees relied upon the assistance
of counsel to the Independent Trustees and counsel to the Trust.

Throughout the year, the Independent Trustees regularly met in executive
sessions separately from the Interested Trustees of the Trust and any officers
of Pioneer Investment Management, Inc., the Trust's adviser (the "Investment
Adviser"), or its affiliates. While the Trustees, including the Independent
Trustees, act on all major matters relating to the Trust, a significant portion
of the activities of the Board of Trustees (including certain of those described
herein) is conducted through committees whose members are comprised exclusively
of Independent Trustees. Such committee meetings are attended by officers of the
Trust or the Investment Adviser to the extent requested by the committee.

In evaluating the Management Contract, the Trustees conducted a review that was
specifically focused upon the renewal of the Management Contract, and also
relied upon their knowledge, resulting from their meetings throughout the year,
of the Investment Adviser, its services and the Trust. Both in meetings
specifically addressed to renewal of the Management Contract and at other
meetings during the course of the year, the Trustees, including the Independent
Trustees, received materials relating to the Investment Adviser's investment and
management services under the Management Contract. These materials included
information on (i) the investment performance of the Trust, a peer group of
funds and an index, in each case selected by the Independent Trustees for this
purpose, (ii) the general investment outlook in the markets in which the Trust
invests, (iii) the procedures employed to determine the value of each of the
Trust's assets, (iv) the Investment Adviser's management of the relationships
with the Trust's unaffiliated service providers, (v) the record of compliance
with the Trust's investment policies and restrictions and with the Trust's Code
of Ethics and the structure and responsibilities of the Investment Adviser's

42


Pioneer High Income Trust
--------------------------------------------------------------------------------

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

compliance department, (vi) the nature, cost and character of non-investment
management services provided by the Investment Adviser and its affiliates, (vii)
the disclosures included in the Trust's reports to shareowners, (viii) analyses
of the benefits and costs of the use of leverage through the issuance of the
Trust's preferred shares and the sensitivity of such analysis to changes in
interest rates and (ix) the discount or premium of the market price of the
Trust's common stock relative to its net asset value and measures that are or
could be taken to address any discount.

Specifically in connection with the Independent Trustees' review of the
Management Contract, the Independent Trustees requested and the Investment
Adviser provided additional information in order to evaluate the quality of the
Investment Adviser's services and the reasonableness of the fee under the
Management Contract. Among other items, this information included data or
analyses of (1) investment performance for one year and three year periods for
the Trust and a peer group selected by the Independent Trustees for this
purpose, (2) management fees incurred by a peer group of funds selected by the
Independent Trustees for this purpose, (3) the advisory fees of comparable
portfolios of other clients of the Investment Adviser, (4) expense ratios for
the Trust and a peer group of funds selected by the Independent Trustees for
this purpose, (5) the overall organization of the Investment Adviser, (6) the
Investment Adviser's financial results and condition, including its and certain
of its affiliates profitability from services performed for the Trust, (7)
administrative reimbursements paid to the Investment Adviser or affiliates, (8)
investment management staffing, and (9) operating expenses paid to third
parties.

The following summarizes factors considered by the Trustees in connection with
reviewing the information described above and their renewal of the Trust's
Management Contract. The Trustees did not identify any single factor as
all-important or controlling, and the summary does not detail all the matters
that were considered.

A. Ancillary Benefits to Shareowners. The Trustees considered the benefits to
   shareowners of investing in a closed-end fund that is part of an established
   group of open and closed-end funds. The Trustees also noted that the
   relationship of the market price relative to the Trust's net assets
   attributed to its common shares was

                                                                              43

FACTORS CONSIDERED BY THE INDEPENDENT TRUSTEES IN
APPROVING THE MANAGEMENT CONTRACT                                  (continued)
--------------------------------------------------------------------------------

   comparable relative to other closed-end funds with similar investment
   approaches.

B. Compliance and Investment Performance. The Trustees determined that the
   Investment Adviser had policies and systems reasonably designed to achieve
   compliance with the Trust's investment objective and regulatory requirements.
   The Trustees also reviewed the Trust's investment performance based on total
   return, as well as the Trust's performance compared to both the performance
   of a peer group and an index, in each case selected by the Independent
   Trustees for this purpose. The Trust's performance based on total return was
   in the first quintile of the peer group for the 12 months ended June 30, 2005
   and was in the second quintile for the three years ended June 30, 2005. (In
   all quintile rankings referred to throughout this discussion first quintile
   is most favorable to the Trust's shareowners. Thus, highest relative
   performance would be first quintile and lowest relative expenses also would
   be first quintile.) The Trustees considered the yield (gross of expenses) to
   the Trust's common shareholders compared to the yield (as of June 30, 2005)
   of the Merrill Lynch Global High Yield and EMP index. The Trustees concluded
   that the performance of the Trust supported the continuation of the
   Management Contract.

C. The Investment Adviser's Personnel and Methods. The Trustees reviewed the
   background of members of the team responsible for the daily management of the
   Trust and the Trust's investment objective and discipline. The Independent
   Trustees also have had discussions with senior management of the Investment
   Adviser responsible for investment operations and the senior management of
   the Investment Adviser's fixed income group. Among other things, the Trustees
   considered the number, education and experience of the Investment Adviser's
   investment staff and their use of technology and emphasis on analytics in
   view of the risk profile of securities in which the Trust invests. The
   Trustees concluded that the Investment Adviser had the quality and depth of
   personnel and the well-developed methods essential to performing its duties
   under the Management Contract.

D. Nature and Quality of Other Services. The Trustees considered the nature,
   quality, cost and extent of other services provided to shareowners of the
   Trust, including administrative and shareowner

44


Pioneer High Income Trust
--------------------------------------------------------------------------------

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

   services performed by the Investment Adviser under the Management Contract.
   The Trustees also considered the reasonableness of the arrangements for
   reimbursement of the Investment Adviser's out-of-pocket costs and expenses,
   including overhead, for certain administrative services that the Investment
   Adviser is not required to provide under the Management Contract. The
   Trustees also considered the nature and extent of the other services provided
   by the Investment Adviser's affiliates under other contracts and its
   supervision of third party service providers. Based on these considerations,
   the Trustees concluded that the nature, quality, cost and extent of such
   services are satisfactory and reliable and serve the shareowners of the Trust
   well.

E. Management Fee and Expenses. The Trustees considered the Investment Adviser's
   fee under the Management Contract relative to the management fees charged by
   a peer group of funds selected by the Independent Trustees for this purpose
   using data provided by an independent third party. The Trust's management fee
   for the 12 months ended June 30, 2005 was in the second quintile relative to
   the management fees paid by the other funds in that peer group for the
   comparable period. The Trustees determined that the fee under the Management
   Contract was reasonable and fair in light of both the overall nature and
   quality of services provided by the Investment Adviser and the fees charged
   by the funds in the peer group. The Trustees also considered the Trust's
   expense ratio and expense ratios of a peer group of funds selected by the
   Independent Trustees for this purpose. The Trust's expense ratio for the 12
   months ended June 30, 2005 was in the second quintile of the applicable peer
   group for the most recent fiscal year of the peer group for the comparable
   period. The Trustees concluded that the Trust's overall expense ratio was
   reasonable compared to that of similar funds.

F. Profitability. The Trustees considered the level of the Investment Adviser's
   profits with respect to the management of the Pioneer funds, including
   details with respect to the Trust. This consideration included a review of
   the Investment Adviser's methodology in allocating certain of its costs to
   the management of each fund. The Trustees also considered the financial
   results realized by the Investment Adviser in connection with the operation
   of the Trust. They further considered the profits realized by the Investment
   Adviser and its affiliates from non-fund businesses that may

                                                                              45

   benefit from or be related to the Trust's business. The Trustees considered
   the Investment Adviser's profit margins in comparison with the limited
   available industry data. The Trustees concluded that the Investment Adviser's
   profits from management of the Pioneer funds, including the financial results
   derived from the Trust, bear a reasonable relationship to the services
   rendered and are fair for the management of the Trust in light of the
   business risks involved.

G. Economies of Scale. The Trustees considered whether the Trust has
   appropriately benefited from any economies of scale, and whether there is
   potential for realization of any further economies of scale. Since the Trust
   is a closed-end fund and its size is relatively stable and at the level of
   assets that was anticipated when the management fee was initially set, the
   Trustees concluded that economies of scale were not a relevant consideration.

H. Other Benefits to the Investment Adviser. The Trustees also considered the
   character and amount of fees paid by the Trust, other than under the
   Management Contract, for services provided by the Investment Adviser and
   affiliates. The Trustees further considered the revenues and profitability of
   the Investment Adviser's businesses other than the fund business, including
   the Investment Adviser's institutional investment advisory business. The
   Trustees considered the intangible benefits that accrue to the Investment
   Adviser and its affiliates by virtue of its relationship with the Trust and
   the Pioneer funds as a group. The Trustees concluded that all these types of
   benefits accruing to the Investment Adviser were reasonable in the context of
   the overall relationship between the Investment Adviser and the Trust.

Conclusion. The Trustees, in light of the Investment Adviser's overall
performance, considered it appropriate to continue to retain the management
services of the Investment Adviser. Based on their evaluation of all material
factors deemed relevant and the advice of independent counsel, the Trustees
concluded that the Management Contract with the Trust is fair and reasonable and
voted to approve the continuation of the Management Contract for another year.

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,

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

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

                  SECTION I - POLICY PURPOSE AND APPLICABILITY

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

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

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

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

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

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

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

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

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


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

Non-Audit Services
Beginning with non-audit service contracts entered into on or after May 6,
2003, the effective date of the new SEC pre-approval rules, the Trust's audit
committee is required to pre-approve services to affiliates defined by SEC
rules to the extent that the services are determined to have a direct impact
on the operations or financial reporting of the Trust. For the years ended
March 31, 2006 and 2005, there were no services provided to an affiliate that
required the Trust's audit committee pre-approval.


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

N/A

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

The aggregate non-audit fees for the Trust and affiliates, as previously
defined, totaled approximately $15,300 in 2006 and $15,100 in 2005.

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


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

The Fund's independent auditor, Ernst &
Young LLP ("E&Y"), has advised the Audit
Committee of the Fund's Board of Trustees that
E&Ys Spanish affiliate (E&Y Spain) performed
certain non-audit work for Pioneer Global
Investments Limited ("PGIL"), an affiliate of the
Funds investment adviser.  The services involved
the receipt and disbursement of monies transferred
to E&Y Spain by PGIL in payment of individual
payroll and related income tax withholdings due on
returns prepared by E&Y Spain for certain PGIL
employees located in Spain from February 2001 to
October 2005.  E&Y became auditors of the Fund in
May 2002.  These payroll and tax services were
discontinued in November 2005.  The annual fee
received by E&Y Spain for all such services totaled
approximately 9,000 Euro per year. E&Y has informed
the Audit Committee that based on its internal
reviews and the de minimus nature of the services
provided and fees received, E&Y does not believe
its independence with respect to the Fund has been
impaired or that it is disqualified from acting as
independent auditors to the Fund.

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

The registrant has a separately-designated standing audit
committe eestablished in accordance with Section

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

                            VERSION DATED July, 2004

                                    Overview

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

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

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

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

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

                                       1


                             Proxy Voting Procedures

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

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

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

                                       2


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

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

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

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

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

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

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

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

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

                                       3


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

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

   Share-Blocking

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

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

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

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

       o   Retains a record of the vote cast;

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

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

                                       4


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

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

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

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

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

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

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

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

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

                                       5


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

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

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

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

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

   We will generally support these and similar management proposals:

       o    Corporate name change.

       o    A change of corporate headquarters.

       o    Stock exchange listing.

       o    Establishment of time and place of annual meeting.

       o    Adjournment or postponement of annual meeting.

       o    Acceptance/approval of financial statements.

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

       o    Approval of minutes and other formalities.

                                       6


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

       o    Amendments to authorized signatories.

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

       o    Acceptance of labor agreements.

       o    Appointment of internal auditors.

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

Auditors
     We normally vote for proposals to:

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

       o    Restore shareholder rights to ratify the auditors.

     We will normally oppose proposals that require companies to:

       o    Seek bids from other auditors.

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

       o    Indemnify auditors.

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

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

                                       7


     General Board Issues
     Pioneer will vote for:

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

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

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

       o    Election of an honorary director.

     We will vote against:

       o    Minimum stock ownership by directors.

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

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

       o    Requirements to provide two candidates for each board seat.

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

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

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

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

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

     We will also vote against:

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

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

                                       8


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

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

       o    Contested election of directors.

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

       o    Mandatory retirement policies.

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

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

     Pioneer will vote for:

       o    Cumulative voting.

       o    Increase ability for shareholders to call special meetings.

       o    Increase ability for shareholders to act by written consent.

       o    Restrictions on the ability to make greenmail payments.

       o    Submitting rights plans to shareholder vote.

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

       o    Opting out of the following state takeover statutes:

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

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

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

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

                                       9


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

     o Fair price provisions.

     o Authorization of shareholder rights plans.

     o Labor protection provisions.

     o Mandatory classified boards.

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

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

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

       o    Proposals that allow shareholders to nominate directors.

     We will vote against:

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

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

       o    Classes of shares with unequal voting rights.

       o    Supermajority vote requirements.

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

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

       o    Extension of advance notice requirements for shareholder proposals.

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

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

                                       10


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

     Pioneer will vote for:

       o    Changes in par value.

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

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

       o    Bond issuance.

       o    Increases in "ordinary" preferred stock.

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

       o    Cancellation of company treasury shares.

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

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

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

     o Number of shares currently available for issuance;

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

     o Proposed use of the additional shares; and

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

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

       o    Proposals to submit private placements to shareholder vote.

       o    Other financing plans.

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

                                      11


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

     Pioneer will vote for:

       o    401(k) benefit plans.

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

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

     o Amendments to performance plans to conform with OBRA;

     o Caps on annual grants or amendments of administrative features;

     o Adding performance goals; and

     o Cash or cash-and-stock bonus plans.

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

       o    Require that option repricings be submitted to shareholders.

       o    Require the expensing of stock-option awards.

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

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

                                       12


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

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

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

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

            A = Shares reserved for plan/amendment,

            B = Shares available under continuing plans,

            C = Shares granted but unexercised and

            D = Shares outstanding.

       o    The plan must not:

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

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

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

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

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

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

       o    All other employee stock purchase plans.

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

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

                                       13


     We will vote against:

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

       o    Elimination of stock option plans.

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

       o    Limits on executive and director pay.

       o    Stock in lieu of cash compensation for directors.

     Corporate Governance
     Pioneer will vote for:

       o    Confidential Voting.

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

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

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

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

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

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

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

     We will vote against:

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

       o    Limitations on stock ownership or voting rights.

       o    Reduction in share ownership disclosure guidelines.

                                       14


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

       o    Mergers and acquisitions.

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

       o    Debt restructurings.

       o    Conversion of securities.

       o    Issuance of shares to facilitate a merger.

       o    Private placements, warrants, convertible debentures.

       o    Proposals requiring management to inform shareholders of merger
            opportunities.

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

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

     Pioneer will vote for:

       o    Establishment of new classes or series of shares.

       o    Establishment of a master-feeder structure.

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

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

       o    Approval of new or amended advisory contracts.

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

       o    Authorization for, or increase in, preferred shares.

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

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

                                       15


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

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

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

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

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

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

                                       16



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

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


(a)(1)

As of the date of this report,  day-to-day management of the fund's portfolio is
the responsibility of Andrew Feltus. Mr. Feltus is supported by the fixed income
team.  Members of this team manage other  Pioneer funds  investing  primarily in
fixed income  securities.  The portfolio manager and the team also may draw upon
the research and investment  management  expertise of the global  research team,
which  provides  fundamental  research on companies  and  includes  members from
Pioneer's affiliate,  Pioneer Investment  Management Limited. Mr. Feltus, a vice
president,  joined Pioneer in 1994 and has been an investment  professional  for
more than 10 years.

(a)(2)

Other Accounts Managed by the Portfolio Manager. 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, 2006. 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 interests 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  interests.  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.

(a)(3)

Compensation of Portfolio Managers. Pioneer has adopted a system of compensation
for  portfolio  managers  and  seeks to align  the  financial  interests  of the
portfolio managers with both those of shareholders of the accounts the portfolio
managers  manage,  through  incentive  payments  based  in part on the  relative
investment  performance  of those  funds,  and also  Pioneer  through  incentive
payments   based  in  part  on  Pioneer's   financial   performance.   Pioneer's
compensation  arrangements  with its  portfolio  managers are  determined on the
basis of the portfolio  manager's overall services to Pioneer and its affiliates
and not on the basis of  specific  funds or  accounts  managed by the  portfolio
manager.  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 aligns the financial  incentives of Pioneer and the  investment
professional.  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 performance of all of
               the accounts managed by the portfolio manager (which includes the
               fund and any other  accounts  managed by the  portfolio  manager)
               over a one-year period (20% weighting) and four-year  period (80%
               weighting),  measured  for  periods  ending on  December  31. The
               accounts,  which include the fund,  are ranked against a group of
               mutual funds with similar  investment  objectives  and investment
               focus (60%) and a broad-based  securities  market index measuring
               the  performance  of the same  type of  securities  in which  the
               accounts  invest  (40%),  which,  in the case of the fund is the
               Merrill Lynch High Yield Master II Index. As a result of these
               two benchmarks,  the  performance  of the  portfolio manager for
               compensation  purposes is measured  against 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.
