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.

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. Expenses Paid on a $1,000 Investment in Pioneer Global High Yield Fund Based on actual returns from November 1, 2004 through April 30, 2005 Share Class A B C - -------------------------------------------------------------------------------- Beginning Account Value $1,000.00 $1,000.00 $1,000.00 On 11/1/04 Ending Account Value $1,041.70 $1,037.40 $1,036.80 On 4/30/05 Expenses Paid During Period* $ 4.66 $ 8.79 $ 8.43 * Expenses are equal to the Fund's annualized expense ratio of 0.92%, 1.74% and 1.67% for Class A, Class B and Class C shares, respectively, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the partial year period). 7 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- COMPARING ONGOING FUND EXPENSES (continued) - -------------------------------------------------------------------------------- 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.

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. 9 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 4/30/05 (continued) - -------------------------------------------------------------------------------- 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. 10 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- 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.

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 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 4/30/05 (unaudited) (continued) - -------------------------------------------------------------------------------- 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 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- 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. 38 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 4/30/05 (unaudited) (continued) - -------------------------------------------------------------------------------- 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. 40 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- 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 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- 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 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- 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 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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 - -------------------------------------------------------------------------------- THE PIONEER FAMILY OF MUTUAL FUNDS - -------------------------------------------------------------------------------- Please consider a fund's investment objectives, risks, charges and expenses carefully before investing.

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.

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.
