LETTER TO SHAREOWNERS 10/31/03
- --------------------------------------------------------------------------------

Dear Shareowner,
- --------------------------------------------------------------------------------
The stock market rally that began last spring extended into late summer as signs
of an economic recovery accumulated. Gross domestic product, a tally of all
goods and services produced in the United States, expanded, thanks to increased
personal consumption, housing and business spending, low short-term interest
rates and lower taxes on individuals. While broader market indicators managed
small gains, the NASDAQ Composite rose sharply in the third quarter as investors
sensed that companies might soon boost technology outlays. September's dip in
consumer expectations linked to slow job creation, plus cutbacks in OPEC oil
production, drove markets off their highest levels. Investors also kept an eye
on the news, as U.S. troops came under daily fire in Iraq and tensions elsewhere
remained.

As the economy appeared to strengthen, investors who had sought safety in U.S.
Treasury issues grew less risk-averse. As a result, corporate bonds moved
broadly higher and the Treasury bond rally stalled. Some of the biggest gains
were recorded among lowerrated, high-yield bonds whose issuers often depend on a
strong economy to boost earnings. Bonds in emerging and developed markets also
did well, as economies stabilized and currencies rose against the slumping U.S.
dollar.

Stocks and bonds, bonds and stocks

Over the past few years, investor sentiment has swung from stocks to bonds and
back again, from U.S. government securities to corporate and international
issues. Each sector has spent time in the spotlight or backstage, delivering
periods of stronger or weaker performance relative to one another.

With sectors constantly moving in and out of favor, how can you increase your
chances of holding investments that are performing well? By owning several kinds
of securities, not just one or two. Through a process called asset allocation,
you can create an investment mix that reflects your needs, taking into account
such factors as your age, your financial goals and their timing, and, of course,
your comfort level where risk is concerned.

Asset allocation is only one area in which a qualified investment professional
can serve you well. Ask your advisor to review how shifting markets may have
affected your asset allocation recently. And if you've never thought about asset
allocation before, now is the best time to start.

Like everyone at Pioneer, I appreciate your continued confidence in our products
and services.

Respectfully,

/s/ Osbert Hood

PORTFOLIO MANAGEMENT DISCUSSION 10/31/03
- --------------------------------------------------------------------------------

High-yield bond markets throughout the world rose during the 12 months ended
October 31, 2003, as investors grew more aggressive in the face of evidence that
economic growth was beginning to accelerate. The declining value of the U.S.
dollar on international currency markets also gave further support to bonds
denominated in foreign currencies. 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 12-month period.

Q:  How did the Fund perform?

A:  The Fund performed exceptionally well. For the 12 months ended October 31,
    2003, the Fund's Class A shares had a total return of 45.58%, at net asset
    value. During the same period, the Merrill Lynch Global High Yield &
    Emerging Markets Plus Index returned 34.69%, while the Merrill Lynch High
    Yield Master II Index, a benchmark for the U.S. high-yield market, returned
    33.10%. The Fund's 30-day SEC yield on October 31, 2003 was a competitive
    7.39%.

Q:  What factors were responsible for this performance?

A:  It would not be too much of an overstatement to say that virtually all
    high-yield markets gained during the period. In addition, our international
    diversification helped substantially as the U.S. dollar declined in value
    versus major foreign currencies. Our emphasis on the euro, Canadian dollar
    and South African rand added to performance as those countries' currencies
    gained in value versus the dollar by 17.06%, 18.08% and 45.09%,
    respectively.

    The fiscal year began with high-yield bonds, both U.S. and foreign, selling
    at extremely depressed prices. Economic growth was sluggish at a time when
    many U.S. companies were caught up in a series of corporate and accounting
    scandals that threatened to undermine the prices of corporate stocks and
    bonds. In addition, emerging markets were in the doldrums as investors
    worried about both the world economy and uncertainties in individual
    countries, most notably Brazil, which faced a presidential election. The
    investment backdrop quickly turned favorable, however. A key event was the
    decision of the U.S. Federal Reserve in early November 2002 to cut
    short-term interest rates by an additional one-half of one percentage point.
    That injected new liquidity into the market and encouraged investors to
    shift funds into riskier sectors, such as equities, high yield and emerging
    market sectors. At the same time, new data suggested that the economy was
    gaining strength, improving the outlook for corporate profits and
    encouraging investors to become less risk averse. This condition also caused
    the U.S. dollar to weaken, helping the competitive positions of many

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

    American manufacturers while at the same time increasing the potential
    returns of foreign investments.

Q:  What were your principal strategies during the period?

A:  Encouraged by the Federal Reserve Board's interest-rate reductions and the
    impending cuts in federal tax rates, we focused on companies in sectors that
    benefit from cyclical recoveries. The companies included many commodity
    producers and technology companies. In addition, we thought the U.S. dollar
    would continue to be weak, and we overweighted foreign currency-denominated
    bonds. While we slightly underweighted emerging-market debt, we tended to
    concentrate our investments in some of the best-performing markets, such as
    Russia and Brazil. In the latter, the newly elected president turned out to
    be friendlier to business and debt holders than expected and he initiated a
    series of reforms that stabilized the economy and encouraged investment.

    Diversification is important in managing risk. During the period, the Fund's
    approach was to invest a minimum of one-third of portfolio assets in the
    United States and a minimum of one-third of assets in developed markets
    outside the United States. We had no minimum in the emerging markets, where
    we intended to invest opportunistically as we found compelling values. While
    our process emphasized fundamental research of securities, we also were very
    conscious of the macroeconomic and political factors that can influence the
    performance of individual securities independently of the strength of a
    company's underlying fundamentals.

    Throughout the year, we continued to take advantage of price gains in some
    securities by selling them and reaping profits, redeploying assets into
    other securities that we believed offered superior relative value.

Q:  What were some of the investments that helped performance?

A:  Kinross Gold, a Canadian operator of gold mines, was a good example of a
    high-yield investment in a company positioned to benefit from both rising
    commodity prices and the declining value of the U.S. dollar. The value of
    the bonds of the company gained 28.6% in local currency, even before adding
    the effects of the appreciating Canadian dollar. Freeport-McMoRan, a
    U.S.-based company with extensive copper and gold mining operations in
    Indonesia, also made a major contribution to performance. Another U.S.
    company that added to the Fund's return was Xerox, whose bonds rose
    materially after it successfully put some corporate-governance and
    balance-sheet issues behind it and began to increase earnings.


                                                                               5

PORTFOLIO MANAGEMENT DISCUSSION 10/31/03                             (continued)
- --------------------------------------------------------------------------------

    Emerging market bonds did well. In Brazil, our investment in AmBev, a major
    beer brewer, turned in particularly strong performance. Mobile Telesystems,
    a Russian wireless communications service provider was another significant
    contributor, as was Vitro, a Mexican gas producer.

Q:  In a good year, did you have any disappointments?

A:  Yes. While performance was generally aided by our commodity holdings, our
    investment in the U.S. paper company Fibermark hurt the Fund's
    performance. The paper industry did not do as well as other commodity
    industries and Fibermark ran into its own operational problems. As a
    result, the bond price declined. In general, our emerging markets holdings
    performed well. There were exceptions, however. Our investment in
    sovereign bonds of the Dominican Republic detracted from performance as
    the securities were pulled down because of a national banking crisis.

Q: What is your investment outlook?

A:  We think the outlook for high-yield bonds continues to be favorable, but we
    also believe investors should have realistic expectations for performance.
    The returns of the past year came as bonds bounced back from the bottom of
    the market. Such returns are unlikely to be sustained.

    That being said, we think the environment for high-yield investments
    continues to be good. The U.S. Federal Reserve has sent out strong signals
    that it intends to keep short-term rates low, and the economy appears to be
    gaining strength. This factor should help corporations increase their
    earnings and support the performance of high-yield corporate bonds. At the
    same time, we anticipate that the U.S. dollar will continue to be weak,
    although it probably will not decline as much as it did during the last
    year. Foreign-currency-denominated bonds should offer good opportunities. In
    particular, we believe the European high-yield market is less efficient than
    other markets because it is relatively young and less liquid. As a result of
    that inefficiency, we have been finding very attractive European bonds that
    we believe are undervalued relative to comparable U.S. securities.

    We expect to continue to keep the Fund well diversified, seeking
    opportunities in the United States, Europe and the emerging markets.

NOTES TO FINANCIAL STATEMENTS 10/31/03
- --------------------------------------------------------------------------------

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). To
date, no shares have been offered to the public. The Fund shares outstanding at
October 31, 2003 are owned by PFD. The investment objective of the Fund is to
maximize total return through a combination of income and capital appreciation.


The Fund's financial statements have been prepared in conformity with accounting
principles generally accepted in the United States of America 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 periods. Actual results could differ from those estimates. The
following is a summary of significant accounting policies consistently followed
by the Fund, which are in conformity with those generally accepted in the
investment company industry:


A. Security Valuation

    Security transactions are recorded as of trade date. Securities 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. Market discounts and
    premiums are accreted or amortized daily; respectively maturity basis and
    are included in interest income on a yield-to-maturity basis with a
    corresponding increase in the cost basis of the security. Interest income,
    including interest on income bearing cash accounts, is recorded on the
    accrual basis, net of unrecoverable foreign taxes


16


Pioneer Global High Yield Fund

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

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

    withheld at the applicable country rates. Temporary cash investments are
    valued at amortized cost.

    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. 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 or 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 possible imposition of adverse governmental laws or
    currency exchange restrictions.


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.


                                                                              17


Pioneer Global High Yield Fund

- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 10/31/03                               (continued)
- --------------------------------------------------------------------------------

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 October 31, 2003, 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 characterization of distributions to shareowners for financial reporting
    purposes is determined in accordance with federal income tax rules.
    Therefore, the source 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 distributions paid during the years ended October 31,
    2003 and 2002 were as follows:



- --------------------------------------------------------------------------------
                                  2003         2002

    Total                                 $106,092
- --------------------------------------------------------------------------------



     At October 31, 2003, The Fund reclassified $18,017 to reduce accumulated
     net realized gain on investments and $18,017 to decrease accumulated
     distributions in excess of net investment income. This reclassification has
     no impact on the net assets of the Fund and presents the Fund's capital
     accounts on a tax basis.


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 no
     underwriting commissions on the sale of Fund shares during the year ended
     October 31, 2003.


F.   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
     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
     account of the Fund. The loans are secured by collateral of at least 102%,
     at all times, of the fair value of the loaned securities. The amount of the
     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
     agreements to recover the securities on loan from the borrower on demand.
     The Fund invests cash collateral in the Securities Lending


                                                                              19

REPORT OF INDEPENDENT AUDITORS
- --------------------------------------------------------------------------------

To the Board of Trustees and Shareowners of
Pioneer Global High Yield Fund:

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Pioneer Global High Yield Fund (the "Fund") as
of October 31, 2003, and the related statement of operations for the year then
ended, and the statements of changes in net assets and the financial highlights
for each of the two years in the period then ended. These financial statements
and financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits. The financial highlights for the
period ended October 31, 2001 were audited by other auditors who have ceased
operations and whose report, dated December 7, 2001, expressed an unqualified
opinion on those financial highlights.

We conducted our audits in accordance with auditing standards generally accepted
in the 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. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements and financial highlights. Our procedures included
confirmation of securities as of October 31, 2003, by correspondence with the
custodian and brokers or by other appropriate auditing procedures where replies
from brokers were not received. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. 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 Global High Yield Fund at October 31, 2003, the results of its
operations for the year then ended, and the changes in its net assets and the
financial highlights for each of the two years in the period then ended in
conformity with accounting principles generally accepted in the United States.

                                                           /s/ Ernst & Young LLP

        (2) Full, fair, accurate, timely, and understandable disclosure in

(c) The registrant must briefly describe the nature of any amendment, during the
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

undertaking to provide its code of ethics to any person without charge, upon
request, pursuant to paragraph (f)(3) of this Item.

a provision of its code of ethics that applies to the registrant's principal

        or persons performing similar functions, as an exhibit to its annual
        report on this Form N-CSR;

        (2) Post the text of such code of ethics on its Internet website and

         committee; or

    (ii) Does not have an audit committee financial expert serving on its audit
         committee.

The registrant's Board of Trustees has determined that the registrant has at
least one audit committee financial expert.

    (2) If the registrant provides the disclosure required by paragraph
(a)(1)(i) of this Item, it must disclose the name of the audit committee
financial expert and whether that person is "independent." In order to be
considered "independent" for purposes of this Item, a member of an audit
committee may not, other than in his or her capacity as a member of the audit
committee, the board of trustees, or any other board committee:

    (i)  Accept directly or indirectly any consulting, advisory, or other
         compensatory fee from the issuer; or

Ms. Marguerite A. Piret, an independent trustee, is such an audit committee
financial expert.

financial expert.

Not applicable.

(b) Disclose, under the caption AUDIT-RELATED FEES, the aggregate fees billed in
each of the last two fiscal years for assurance and related services by the

paragraph (a) of this Item. Registrants shall describe the nature of the

comprising the fees disclosed under this category.

described in paragraph (c)(7) of Rule 2-01 of Regulation S-X.

    (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.

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.

(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.

(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.

Not applicable; to be answered on annual submissions after December 15, 2003.
