LETTER TO SHAREOWNERS 4/30/05
- --------------------------------------------------------------------------------

Dear Shareowner,
- --------------------------------------------------------------------------------

U.S. stocks moved higher early in 2005, with the Standard & Poor's 500 Stock
Index and the Dow Jones Industrial Average advancing to three-year highs in
early March. But from then on, soaring prices for heating oil and gasoline, plus
the steady ratcheting up of interest rates by the Federal Reserve Board
overwhelmed sentiment and caused stocks to retrace their gains. By the end of
April, the Dow Industrials, the S&P 500 and the tech-heavy NASDAQ composite were
in negative territory for the year.

With investors less welcoming of risk and the economy giving mixed signals,
value stocks were more resilient than growth stocks. In addition,
large-capitalization stocks held up better than small- and mid-sized issues that
might be more vulnerable in an economic "soft patch," in the phrase of Federal
Reserve Board Chairman Alan Greenspan.

Determined to prevent damaging inflation, the Fed has repeatedly raised
short-term interest rates. As a result, bond returns were modestly negative in
most sectors. Fixed-income investors also became more risk-averse; high-yield
and other corporate sectors retrenched after a run of stellar performance while
Treasuries and mortgage-backed securities showed small declines, with long-term
issues showing positive. Municipal revenue bonds trended higher even against a
backdrop of heavy new issuance by states and localities.

Higher U.S. interest rates enhanced the dollar's appeal and brought at least a
pause in its long, sharp drop. But the stronger dollar muted returns for U.S.
investors in overseas markets. Globally, economies rich in metals and other
industrial commodities continued to thrive on heavy demand from China and
elsewhere. Meanwhile, growth in Japan may have stalled, and Europe's expansion
moved ahead slowly.

We believe that the U.S. economy and corporate earnings will continue to grow at
a moderate pace. Oil prices have receded from their record highs, but high
energy costs and rising interest rates may be in the headlines for a while.
Looking beyond present concerns, Pioneer's global investment experts continue to
find stocks and bonds with attractive long-term potential for our domestic and
international funds.

Expanding your opportunities

This period was like all others; different classes of investments delivered
different returns. That's why allocating your portfolio across several
investment categories is one way to seek wider opportunities. Pioneer's
disciplined approach and growing range of products are designed to help you
achieve this important objective. For thoughtful guidance on how to align your
portfolio with your goals, contact your financial professional.

Please consider a fund's investment objective, risks, charges and expenses
carefully before investing. The prospectus contains this and other information
about each fund and should be read carefully before you invest or send money. To
obtain a prospectus and for other information on any Pioneer fund, contact your
financial advisor, call 1-800-225-6292 or visit our web site at

Respectfully,

/s/ Osbert M. Hood

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.

POP returns reflect deduction of maximum 4.5% sales charge. NAV results
represent the percent change in net asset value per share. Returns would have
been lower had charges been reflected. All results are historical and assume the
reinvestment of dividends and capital gains. Other share classes are available
for which performance and expenses will differ.

The Fund will charge a 2% redemption fee on proceeds from shares redeemed or
exchanged within 30 days of acquiring (either by purchasing or exchanging) Fund
shares. See the prospectus for complete details.

Performance results reflect any applicable expense waivers in effect during the
periods shown. Without such waivers Fund performance would be lower. Waivers may
not be in effect for all funds. Certain fee waivers are contractual through a
specified period. Otherwise, fee waivers can be rescinded at any time. See the
prospectus and financial statements for more information.

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

The Fund's investment advisor, Pioneer Investment Management, Inc., reduced its
management fee and subsidized other Fund expenses; otherwise, returns would have
been lower.

Index comparison begins on August 31 2001. The ML Global High Yield and Emerging
Markets Plus Index tracks the performance of the below- and border-line
investment-grade global debt markets denominated in the major developed market
currencies. The Index includes sovereign issuers rated BBB1 and lower along with
corporate issuers rated BB1 and lower. There are no restrictions on issuer
country of domicile. However, the bonds must be publicly issued in a developed
market (i.e., investment-grade country). Index returns are calculated monthly,
assume reinvestment of dividends and, unlike Fund returns, do not reflect any
fees, expenses or sales charges. You cannot invest directly in an Index.

As a shareowner in the Fund, you incur two types of costs:

(1)  ongoing costs, including management fees, distribution and/or service
     (12b-1) fees, and other Fund expenses; and

(2)  transaction costs, including sales charges (loads) on purchase payments.

This example is intended to help you understand your ongoing expenses (in
dollars) of investing in the Fund and to compare these costs with the ongoing
costs of investing in other mutual funds. The example is based on an investment
of $1,000 at the beginning of the Fund's latest six-month period and held
throughout the six months.


Using the Tables

Actual Expenses

The first table below provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you paid over the period as
follows:

1.   Divide your account value by $1,000
     Example: an $8,600 account value [divided by] $1,000 = 8.6

2.   Multiply the result in (1) above by the corresponding share class's number
     in the third row under the heading entitled "Expenses Paid During Period"
     to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The table below provides information about hypothetical account values and
hypothetical expenses based on the Fund's actual expense ratio and an assumed
rate of return of 5% per year before expenses, which is not the Fund's actual
return. The hypothetical account values and expenses may not be used to estimate
the actual ending account balance or expenses you paid for the period.

You may use this information to compare the ongoing costs of investing in the
Fund and other funds. To do so, compare this 5% hypothetical example with the 5%
hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the tables are meant to highlight your
ongoing costs only and do not reflect any transaction costs, such as sales
charges (loads) that are charged at the time of the transaction. Therefore, the
table below is useful in comparing ongoing costs only and will not help you
determine the relative total costs of owning different funds. In addition, if
these transaction costs were included, your costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION 4/30/05
- --------------------------------------------------------------------------------

High-yield investments experienced two very different environments during the
six months ending April 30, 2005. During the first half of the period, the
backdrop was very favorable for high-yield investing, as economies throughout
the world continued to expand at healthy rates and corporate profits grew.
However, in the second half of the period, reports of slowing economic growth
raised anxieties, especially as the U.S. Federal Reserve continued to raise
short-term interest rates. In the following discussion, Andrew D. Feltus, a
member of the team managing Pioneer Global High Yield Fund, provides an update
on the Fund, its investment strategies and the investment environment during the
six months.

Q:   How did the Fund perform?

A:   The Fund continued to outdistance its benchmarks and its competitive peer
     group. For the six months ended April 30, 2005, the Fund's Class A shares
     returned 4.17% while Class B and Class C shares returned, respectively,
     3.74% and 3.68%, all at net asset value. During the same six months, the
     Merrill Lynch Global High Yield and Emerging Markets Plus Index rose 1.77%,
     while the Merrill Lynch High Yield Master II Index, a benchmark for the
     domestic high-yield bond market, was flat with a return of 0.00%. For the
     six months, the average return of the 93 competitive funds in the Lipper
     Global Income Fund category was 3.34%.

     The Fund also sustained a good income stream. The 30-day SEC yield for
     Class A shares on April 30, 2005, was 6.80%.

     Performance results reflect any applicable expense waivers in effect during
     the periods shown. Without such waivers fund performance would be lower.
     Waivers may not be in effect for all funds. Certain fee waivers are
     contractual through a specified period. Otherwise, fee waivers can be
     rescinded at any time. See the prospectus and financial statements for more
     information.

     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 were the principal factors affecting performance?

A:   Optimism pervaded high-yield bond markets throughout the world during the
     first half of the period. The U.S. market was riding the crest of a 4%
     growth rate in Gross Domestic Product during 2004. Globally, the 5% growth
     rate was the highest in more than 40 years. With earnings also rising,
     investor confidence in lower-rated debt - whether corporate bonds or
     emerging market sovereign debt - remained high. However, beginning in
     February, concerns started to re-emerge about the sustainability of the
     positive environment, especially in view of the U.S. Federal Reserve
     Board's continued policy to increase short-term interest rates.

     In the United States, those worries were exacerbated by poor earnings
     reports by auto giants General Motors and Ford. The concern was that if
     debt for both GM and Ford were to be downgraded from investment-grade to
     below-investment grade, the two companies would together be responsible for
     15% of the domestic high-yield bond market. This feared massive technical
     change in the high-yield market was enough to send high-yield indices into
     a tailspin. (Note to readers: After the fiscal period ended, the Standard &
     Poor's rating service downgraded the debt of GM and Ford to BB and BB+,
     respectively.)

     Outside the United States, there also was evidence of a slowing of growth
     in Japan and in Europe, but other markets held up better than the U.S.
     high-yield markets.

Q:   What contributed to the Fund's strong relative performance?

A:   When high-yield bonds were most in demand during the first three months of
     the period, we started to sell some of our riskier positions into the
     strong market, adopting a more conservative stance during the final three
     months when the markets corrected. This helped performance. We tended to
     sell the riskier U.S. and European high-yield bonds as well as some
     emerging market debt. Within the emerging markets, we focused on those
     areas that presented less risk, such as Russia and Peru, rather than
     countries with greater risk, such as Venezuela and Turkey. We also reduced
     our exposure to non-dollar currencies. For much of the previous two years,
     our investments in non-dollar currencies had accounted for 20% or more of
     Fund assets, but we reduced that to about 12%. This tactic mitigated the
     effects of the strengthening of the U.S. dollar in the final weeks of the
     period.

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

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

     At the end of the six-month period, on April 30, 2005, we had allocated
     approximately 62% of assets to U.S. high-yield corporate debt; 9% to
     international high-yield bonds; 28% to emerging market debt, and about 1%
     to cash. Average credit quality was B.

     In addition, we tended to have good security selection. Several of our
     holdings, for example, announced initial public stock offerings which
     allowed them to pay down their outstanding high-yield debt. These companies
     included Refco, a financial clearing house, and Celanese, a chemical
     company.

Q:   What were some of the other investments that notably influenced
     performance?

A:   Two of our holdings, Metro PCS, a wireless telecommunications service
     provider, and Ardent Healthcare, a managed care company, bought back
     existing high-yield bonds at large premiums to their current prices. The
     bonds of Seabulk, an oil and shipping services company, also were tendered
     as the company was taken over by Seacore Holdings.

     Merger and acquisition activity played a role in Fund performance.
     Securities of Bombardier, a Canadian airplane and train manufacturer, rose
     as the company sold some of its assets to General Electric, while the value
     of bonds issued by Mobifon Holdings, a Romanian company, appreciated on
     news that the company was being acquired by Vodafone. We sold the Mobifon
     securities.

     Our investments in Brazilian corporate bonds were particularly successful.
     Bonds that did well included those of Braskem, a chemical company, and CSN,
     a steel corporation. Both companies reported strong earnings, and their
     bonds paid above-average income in relation to their credit risks.

     Securities issued by Ispat, a global steel company with operations in
     India, Europe and the United States, also performed well before we reduced
     our position because of concerns about future earnings prospects for the
     steel industry as the economic cycle progressed.

     We also had some disappointments, notably among investments in several
     Asian high-yield corporate bonds, including: Vedanta, an Indian metal
     company; Asia Aluminum, which is based in China, and Noble Group, a
     Singapore-based commodity trader. The value of bonds of all three companies
     declined in the final weeks of the six-month period, despite strong
     fundamentals in all three firms.

                                                                              11

PORTFOLIO MANAGEMENT DISCUSSION 4/30/05                              (continued)
- --------------------------------------------------------------------------------

     We continue to have confidence in these investments, however, and even
     added to our positions to take advantage of the lower prices.

Q:   What is your investment outlook?

A:   We think high-yield bonds again offer reasonably good investment value,
     especially if the Federal Reserve is nearing the conclusion of its cycle of
     interest-rate hikes. We feel if the Fed stops raising rates in the coming
     months, economic growth and fundamentals should continue to be positive,
     and corporate credit should be good.

     We expect to continue to seek investment opportunities through good
     selection of companies, countries and currencies.

Investing in foreign and/or emerging markets securities involves risks relating
to interest rates, currency exchange rates, economic, and political conditions.
Investments in high-yield or lower-rated securities are subject to
greater-than-average risk. When interest rates rise, the prices of fixed-income
securities in the Fund will generally fall. Conversely, when interest rates fall
the prices of fixed-income securities in the Fund will generally rise. Because
the portfolio invests in a limited number of companies a change in one
security's value may have a more significant effect on the portfolio's value.
Investments in the Fund are subject to possible loss due to the financial
failure of underlying securities and their inability to meet their debt
obligations. These risks may increase share price volatility.

Any information in this shareholder report regarding market or economic trends
or the factors influencing the Fund's historical or future performance are
statements of the opinion of Fund management as of the date of this report.
These statements should not be relied upon for any other purposes. Past
performance is no guarantee of future results, and there is no guarantee that
market forecasts discussed will be realized.

1.   Organization and Significant Accounting Policies

Pioneer Global High Yield Fund (the Fund), is a Delaware statutory trust,
registered under the Investment Company Act of 1940 as a non-diversified,
open-end management investment company. The Fund was organized on May 5, 2001
and commenced operations on August 27, 2001. Prior to August 27, 2001 the Fund
had no operations other than those relating to organizational matters and the
initial capitalization of the Fund by Pioneer Funds Distributor, Inc. (PFD). The
Fund's shares, including Class A Shares, were first publicly offered on December
1, 2003. Prior to December 1, 2003, the Fund shares outstanding were owned by
PFD. The investment objective of the Fund is to maximize total return through a
combination of income and capital appreciation.

The Fund offers three classes of shares - Class A, Class B, and Class C shares.
Shares of Class A, Class B, and Class C each represent an interest in the same
portfolio of investments of the Fund and have equal rights to voting,
redemptions, dividends and liquidation, except that each class of shares can
bear different transfer agent and distribution fees and have exclusive voting
rights with respect to the distribution plans that have been adopted by Class A,
Class B, and Class C shareowners, respectively.

The Fund's financial statements have been prepared in conformity with U.S.
generally accepted accounting principles that require the management of the Fund
to, among other things, make estimates and assumptions that affect the reported
amounts of assets and liabilities, the disclosure of contingent assets and
liabilities at the date of the financial statements, and the reported amounts of
income, expenses and gain or loss on investments during the reporting period.
Actual results could differ from those estimates. The following is a summary of
significant accounting policies followed by the Fund in the preparation of its
financial statements, which are consistent with those policies generally
accepted in the investment company industry:

A.   Security Valuation

     Security transactions are recorded as of trade date. The net asset value of
     the Fund is computed once daily, on each day the New York Stock Exchange
     (NYSE) is open, as of the close of regular trading on the NYSE. In
     computing the net asset value, securities are valued at the last sale price
     on the principal exchange where

34


Pioneer Global High Yield Fund

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

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

     they are traded. Fixed income securities with remaining maturities of more
     than 60 days are valued at prices supplied by independent pricing services,
     which consider such factors as Treasury spreads, yields, maturities and
     rating. Valuations may be supplemented by dealers and other sources, as
     required. 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 and may include yield equivalents or a pricing
     matrix. The Fund also may use the fair value of a security, including a
     non-U.S. security, when the closing market price on the principal exchange
     where the security is traded no longer reflects the value of the security.
     As of April 30, 2005, there were no securities fair valued. Temporary cash
     investments are valued at amortized cost.

     Discounts and premiums on debt securities are accreted or amortized daily,
     respectively, on a yield-to-maturity basis into interest income with a
     corresponding increase or decrease in the cost basis of the security.
     Interest income is recorded on the accrual basis, net of unrecoverable
     foreign taxes withheld at the applicable country rates.

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

     The Fund invests in below investment grade (high yield) debt securities and
     preferred stocks. Some of these high yield securities 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 Fund is not diversified, which means that it can invest a
     higher percentage of its assets in any one issuer than a diversified fund.
     Being non-diversified may magnify the Fund's losses from adverse events
     affecting a particular issuer.

     The Fund's investments in foreign markets and countries with limited
     developing markets may subject the Fund to a greater degree of risk than in
     a developed market. These risks include disruptive political or economic
     conditions and the imposition of adverse governmental laws or currency
     exchange restrictions.

                                                                              35

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

B.   Foreign Currency Translation

     The books and records of the Fund 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 Fund 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 Fund's
     financial statements. The Fund 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. At April 30, 2005, the Fund
     had no outstanding portfolio or settlement hedges.

D.   Federal Income Taxes

     It is the Fund'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.

     The amounts and characterizations of distributions to shareowners for
     financial reporting purposes are determined in accordance with

36


Pioneer Global High Yield Fund

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

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

     federal income tax rules. Therefore, the sources of the Fund'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 transactions, or from paid-in capital, depending on the type of
     book/tax differences that may exist.

     The tax character of current year distributions paid will be determined at
     the end of the current fiscal year. The tax character of distributions paid
     during the year ended October 31, 2004 were as follows:



- --------------------------------------------------
                                              2004
- --------------------------------------------------
                                     
Distributions paid from:
   Ordinary income                      $6,066,756
   Long-term capital gain                   15,591
   Return of capital                             -
                                        ----------
    Total                               $6,082,347
                                        ==========
- --------------------------------------------------


     The following shows the components of distributable earnings on a federal
     income tax basis at October 31, 2004:



- --------------------------------------------------
                                         2004
- --------------------------------------------------
                                     
  Undistributed ordinary income      $   77,249
  Capital loss carryforward             (82,339)
  Unrealized appreciation             5,398,616
                                     ----------
    Total                            $5,393,526
                                     ==========
- --------------------------------------------------


     The difference between book basis and tax basis unrealized appre ciation is
     attributable to accrued interest on defaulted bonds.

E.   Fund Shares

     The Fund records sales and repurchases of its shares as of trade date. PFD,
     the principal underwriter for the Fund and a wholly owned indirect
     subsidiary of UniCredito Italiano S.p.A. (UniCredito Italiano), earned
     $247,902 in underwriting commissions on the sale of Class A shares during
     the six months ended April 30, 2005.

                                                                              37

NOTES TO FINANCIAL STATEMENTS 4/30/05 (unaudited)                    (continued)
- --------------------------------------------------------------------------------

F.   Class Allocations

     Distribution fees are calculated based on the average daily net asset value
     attributable to Class A, Class B and Class C of the Fund, respectively (see
     Note 4). Shareowners of each class share all expenses and fees paid to the
     transfer agent, Pioneer Investment Management Shareholder Services, Inc.
     (PIMSS), for its services, which are allocated based on the number of
     accounts in each class and the ratable allocation of related out-of-pocket
     expenses (see Note 3). Income, common expenses and realized and unrealized
     gains and losses are calculated at the Fund level and allocated daily to
     all classes of shares based on their respective percentage of adjusted net
     assets at the beginning of the day.

     The Fund declares as daily dividends substantially all of its net
     investment income. All dividends are paid on a monthly basis. Short-term
     capital gain distributions, if any, may be declared with the daily
     dividends. Distributions to shareowners are recorded as of the ex-dividend
     date. Distributions paid by the Fund with respect to each class of shares
     are calculated in the same manner, at the same time, and in the same
     amount, except that Class A, Class B, and Class C shares can bear different
     transfer agent and distribution fees.

G.   Securities Lending

     The Fund lends securities in its portfolio to certain broker-dealers or
     other institutional investors, with the Fund's custodian acting as the
     lending agent. When entering into a loan, the Fund receives collateral,
     which is maintained by the custodian and earns income in the form of
     negotiated lenders' fees. The Fund also continues to receive interest or
     payments in lieu of dividends on the securities loaned. Gain or loss on the
     fair value of the loaned securities that may occur during the term of the
     loan will be for the account of the Fund. The loans are secured by
     collateral of at least 102%, at all times, of the fair value of the
     securities loaned. The amount of collateral will be adjusted daily to
     reflect any price fluctuation in the value of the loaned securities. The
     Fund has the right under the lending agreement to recover the securities
     from the borrower on demand. The Fund invests cash collateral in the
     Securities Lending Investment Fund, which is managed by Brown Brothers
     Harriman & Co., the Fund's custodian.

2.   Management Agreement

Pioneer Investment Management, Inc. (PIM), a wholly owned indirect subsidiary of
UniCredito Italiano, the Fund's investment adviser, manages the Fund's
portfolio. Management fees are calculated daily at the annual rate of 0.70% of
the Fund's average daily net assets up to $500 million; and 0.65% of the next
$500 million; and 0.60% on the assets over $1 billion.

Through March 1, 2005, PIM has agreed not to impose all or a portion of its
management fee and to assume other operating expenses of the Fund to the extent
necessary to limit Class A expenses to 0.75% of the average daily net assets
attributable to Class A shares; the portion of Fund expenses attributable to
Class B and Class C shares will be reduced only to the extent such expenses are
reduced for Class A shares.

In addition, under the management and administration agreements, certain other
services and costs, including accounting, regulatory reporting and insurance
premiums, are paid by the Fund. At April 30, 2005, $322,722 was payable to PIM
related to management fees, administrative costs and certain other services and
is included in due to affiliates.

3.   Transfer Agent

PIMSS, a wholly owned indirect subsidiary of UniCredito Italiano, provides
substantially all transfer agent and shareowner services to the Fund at
negotiated rates. Included in due to affiliates is $114,732 in transfer agent
fees payable to PIMSS at April 30, 2005.

4.   Distribution and Service Plans

The Fund adopted Plans of Distribution with respect to each class of shares
(Class A Plan, Class B Plan, and Class C Plan) in accordance with Rule 12b-1 of
the Investment Company Act of 1940. Pursuant to the Class A Plan, the Fund pays
PFD a service fee of up to 0.25% of the average daily net assets attributable to
Class A shares in reimbursement of its actual expenditures to finance activities
primarily intended to result in the sale of Class A shares. Pursuant to the
Class B Plan and the Class C Plan, the Fund pays PFD 1.00% of the average daily
net assets attributable to each class of shares. The fee consists of a 0.25%
service fee and a 0.75% distribution fee paid as compensation for personal
services and/or account maintenance

                                                                              39

services or distribution services with regard to Class B and Class C shares.
Included in due to affiliates is $300,511 in distribution fees payable to PFD at
April 30, 2005.

In addition, redemptions of certain classes of shares may be subject to a
contingent deferred sales charge (CDSC). Effective February 1, 2004, a CDSC of
1.00% may be imposed on redemptions of certain net asset value purchases of
Class A shares within 18 months of purchase (12 months for shares purchased
prior to February 1, 2004). Class B shares subscribed on or after December 1,
2004 that are redeemed within five years of purchase are subject to a CDSC at
declining rates beginning at 4.00%, based on the lower of cost or market value
of shares being redeemed. Redemptions of Class C shares within one year of
purchase are subject to a CDSC of 1.00%. Proceeds from the CDSCs are paid to
PFD. The six months ended April 30, 2005, CDSCs in the amount of $74,806 were
paid to PFD.

Effective March 2, 2004, the Fund charges a 2.0% redemption fee on Class A,
Class B, and Class C shares sold within 30 days of purchase. The fee does not
apply to certain types of transactions as described in the Fund's prospectus.
For the six months ended April 30, 2005, the Fund collected $72,608 in
redemption fees, which are included in the Fund's capital account.

5.   Expense Offset Arrangements

The Fund has entered into certain expense offset arrangements with PIMSS
resulting in a reduction in the Fund's total expenses due to interest earned on
cash held by PIMSS. For the six months ended April 30, 2005, the Fund's expenses
were reduced by $2,748 under such arrangements.

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

The Investment Company Act of 1940 requires that both the Board of Trustees and
a majority of the Independent Trustees (collectively "the Trustees") vote
separately annually to approve the Fund'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 Fund to receive quality investment advisory services at a cost deemed
reasonable and in the best interests of the Fund and its shareholders. In making
such determinations, the Independent Trustees relied upon the assistance of
counsel to the Independent Trustees and counsel to the Fund.

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

In evaluating the Management Contract, the Trustees conducted a review that was
specifically focused upon the renewal of the Management Contract, and relied
upon their knowledge, resulting from their meetings throughout the year, of the
Investment Adviser, its services and the Fund. Both in meetings specifically
dedicated 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 (i) information
on the investment performance of the Fund, a peer group of funds and two
indices, in each case selected by the Independent Trustees for this purpose,
(ii) sales and redemption data in respect to the Fund, (iii) the general
investment outlook in the markets in which the Fund invests, (iv) arrangements
in respect of the distribution of the Fund's shares, (v) the procedures employed
to determine the value of each of the Fund's assets, (vi) the Investment
Adviser's management of the relationships with the Fund's unaffiliated service
providers, (vii) the record of compliance with the

                                                                              41

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

Fund's investment policies and restrictions and with the Fund's Code of Ethics
and the structure and responsibilities of the Investment Adviser's compliance
department, (viii) the nature, cost and character of non-investment management
services provided by the Investment Adviser and its affiliates and (ix) the
disclosures included in the Fund's prospectuses and reports to shareholders.

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 and three years and life of the
Fund periods for the Fund 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 Fund 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
Fund, (7) transfer agency fees and administrative reimbursements paid to the
Investment Adviser or affiliates, (8) investment management staffing, and (9)
operating expenses paid to third parties. The Trustees also reviewed information
regarding the potential for the Fund and the Investment Adviser to benefit from
further economies of scale in the management of the Fund in light of reasonable
growth expectations for the Fund and certain of the Fund's expenses that are not
incurred as fees based on a percentage of net assets.

The following summarizes matters considered by the Trustees in connection with
their renewal of the Fund'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 Shareholders. The Trustees considered the benefits to
     shareholders of investing in a Fund that is part of a large number of
     investment companies offering a variety of

42


Pioneer Global High Yield Fund

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

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

     investment disciplines and providing for a large variety of Fund and
     shareholder services.

B.   Compliance and Investment Performance. The Trustees determined that the
     Investment Adviser had policies and systems reasonably designed to achieve
     compliance with the Fund's investment objectives and regulatory
     requirements. The Trustees also reviewed the Fund's investment performance
     based upon total return, as well as the Fund'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 Fund's performance based upon
     total return was in the first quintile of the peer group for the 12 months
     ended June 30, 2004. (In all quintile rankings referred to throughout this
     discussion first quintile is most favorable to the Fund's shareholders.
     Thus, highest relative performance would be first quintile and lowest
     relative expenses also would be first quintile.) The Trustees concluded
     that the performance of the Fund 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 Fund and the Fund'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 equities 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 Fund 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 shareholders of the
     Fund, including administrative and shareholder 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

                                                                              43

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

     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 shareholders of the Fund 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 Fund's
     management fee for the 12 months ended June 30, 2004 was in the third
     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 Fund's expense ratio and expense ratios of a peer group of
     funds selected by the Independent Trustees for this purpose. The Fund's
     expense ratio (after giving effect to the expense limitation) for the 12
     months ended June 30, 2004 was in the first 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 Fund's overall expense ratio (after
     giving effect to the expense limitation) was lower than that of comparably
     sized 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 Fund. 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 Fund. They further considered the profits realized by the
     Investment Adviser and its affiliates from non-fund businesses that may
     benefit from or be related to the Fund's business. The Trustees considered
     the Investment Adviser's profit margins in comparison with the limited
     available industry data. The Trustees concluded

44

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

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

     that the Investment Adviser's profits from management of the Pioneer Funds,
     including the financial results derived from the Fund, bear a reasonable
     relationship to the services rendered and are fair for the management of
     the Fund.

G.   Economies of Scale. The Trustees considered the economies of scale with
     respect to the management of the Fund, whether the Fund had appropriately
     benefited from any economies of scale, and whether there was potential for
     realization of any further economies of scale. Because of break points in
     the management fee, the Trustees concluded that any perceived or potential
     economies of scale would be shared at future asset levels in a reasonable
     manner as the Fund grows in size between Fund's shareholders and the
     Investment Adviser.

H.   Other Benefits to the Investment Adviser. The Trustees also considered the
     character and amount of fees paid by the Fund, other than under the
     Management Contract, for services provided by the Investment Adviser and
     affiliates, including fees for services such as shareholder services. The
     Trustees also considered the receipt of sales loads and payments under Rule
     12b-1 plans in respect to the Pioneer Funds (including the Fund), and
     benefits to the Investment Adviser from the use of "soft" commission
     dollars to pay for research and brokerage services. 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 Fund 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 Fund.

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 Fund is fair and reasonable and
voted to approve the continuation of the Management Contract for another year.

                                                                              45

 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.

    N/A

(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 Fund's independent auditor, Ernst & Young
LLP ("E&Y"), has advised the Securities
and Exchange Commission, the Public Company
Accounting Oversight Board, and the Audit
Committee of the Fund's Board of Trustees that
certain non-audit work performed by E&Y's China
affiliate raised questions regarding E&Y's
independence with respect to its performance of
audit services for the Fund.  In July 2004, E&Y
became aware that member firms in China ("E&Y
China") provided certain tax services to offices of
UniCredito Italiano, S.p.A. ("UCI"), a member of
the Fund's Investment Company Complex.  The
services included receipt and disbursement of
monies transferred to E&Y China by UCI in
payment of individual expatriate income taxes due
on returns prepared by E&Y China for certain UCI
employees located in China from October 1998 to
May 2003.  E&Y became auditors of the Fund in
May 2002.  These expatriate tax services were
discontinued in May 2003.  The fees received by
E&Y China for all such services totaled $3,685.

The Fund's Audit Committee and E&Y have
discussed the matter, including the nature of the
services provided, the personnel involved in
providing the services and the fees received by
E&Y for performing the services.  E&Y has informed
the Audit Committee that based on its internal reviews
and the de minimis nature of the services provided and
fees received, it does not believe its independence
with respect to the Fund has been impaired.

N/A


(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 registrant's principal executive officer and principal financial
officer have concluded, that the registrant's disclosure controls and
procedures are effective based on their evaluation of these controls and

controls subsequent to the date of their evaluation, including any corrective
actions with regard to significant deficiencies and material weaknesses.

in other factors that could significantly affect these controls subsequent to
the date of their evaluation, including any corrective actions with regard
to significant deficiencies and material weaknesses.
