While markets reversed in May (U.S. Treasury bond yields, stock markets, and commodity prices all turned down), we believe the basic fundamental pattern of strong global economic growth remains intact. According to the International Monetary Fund, global economic growth in 2004-5 was the fastest of any two-year period in more than 30 years, and 2006 growth is projected to match 2005 levels. Growth has been broad-based, with Europe, Japan, and emerging market economies all showing strength. The result has been rising prices across a broad range of commodities, rising corporate profits, and rising interest rates. These have been the basic ingredients of the equity bull market and relatively weak bond market over the six months ending April 30, 2006. The bond markets' concern has been that strong economic growth would spark inflation - we have already seen commodity prices rise, and U.S. labor costs are threatening to rise as the economy reaches full employment. In this environment, strong economic growth may lead to inflation and higher interest rates, while slowing economic growth is welcomed by the markets. While first quarter economic growth was strong, it looks as if the slowdown in the U.S. economy that we have been anticipating for the second half of the year may be starting to unfold. The U.S. unemployment rate reached a five-year low of 4.6 percent in May, but employment growth slowed to only 75,000 new jobs, the smallest increase since the Katrina-distorted result of October 2005. The housing market is cooling, as is non-essential consumer spending. The U.S. Federal Reserve has not yet paused in its program of measured increases in short-term interest rates, and it appears likely that the Fed will raise rates again at the end of June. Global stock markets declined in May after the Fed warned that the central bank remains determined to keep inflation low. Fed vigilance against inflation and resolve to hike interest rates as necessary to keep inflation pressures well-contained puts short-term pressure on markets, but is investor-friendly over the intermediate-to-longer term. By restraining inflation, 2 Letter the Fed may limit upward pressure on longer-maturity bond yields and downward pressure on stocks' price/earnings ratios. In summary, we believe a desirable moderate slowing of U.S. economic growth appears likely, with beneficial impacts on inflation and interest rates, while global growth prospects remain strong. We think security market valuations remain reasonable. However, there are no guarantees in investing. We know from a long-view of history that sudden shifts in investor sentiment can occur with little warning. This unpredictability reinforces the importance of Pioneer's message that investors should remain diversified, take a long-term view, and base investment decisions on economic and market fundamentals, rather than on emotion. Our investment philosophy and approach continue to be based on the use of fundamental research to identify a range of opportunities that offer an attractive balance of risk and reward to help Fund shareowners work toward their long-term goals.

With a backdrop of sustained economic growth and improving corporate fundamentals, investors felt confident in taking on credit risk and sought out bonds offering a yield advantage over higher-quality securities. The persistent recovery of the world economy and strong results from high-yielding bonds came despite the continued efforts of the U.S. Federal Reserve Board and other central banks to restrain growth by raising short-term interest rates. In the following discussion, Andrew D. Feltus, leader of the team managing Pioneer Global High Yield Fund, provides an update on the Fund, its investment strategies and the investment environment for the six months ended April 30, 2006. Q: How did the Fund perform? A: In a favorable environment, the Fund's performance surpassed its benchmarks and competitive averages. Pioneer Global High Yield Fund Class A shares had a total return of 7.13%, at net asset value, for the six months ended April 30, 2006. In comparison, the Merrill Lynch Global High Yield and Emerging Markets Plus Index returned 5.76%, while the Merrill Lynch High Yield Master II Index gained 4.98%. The average return of the 457 funds in Lipper's High Current Yield category was 5.10% for the same six months. The Fund also produced an attractive stream of income for shareholders. The 30-day SEC yield for Class A shares, for example, was 6.54% on April 30, 2006. Call 1-800-225-6292 or visit www.pioneerinvestments.com for the most recent month-end performance results. Current performance may be lower or higher than the performance data quoted. 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 Fund performance? A: The sustained economic recovery remained the driving influence on high-yield bond performance for the period. In this environment of strong growth and rising corporate profits, default rates of high-yield corporate debt remained relatively low. Investors showed 4 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- their willingness to accept the credit risks associated with lower-rated, high-yielding investments and high-yield corporate bonds outperformed high-grade bonds. Economies throughout the world continued to expand in the face of the tightening monetary policies of the U.S. Federal Reserve and other central banks. By the end of the period on April 30, 2006, the Fed had raised the Fed funds rate 15 times since June 2004, hiking the rate from 1.00% to 4.75%, with more rate increases anticipated. While some signs were beginning to emerge that the pace of economic growth was slowing, other evidence remained that economies still were growing strongly and that the potential for increased inflation might be building. Gross Domestic Product (GDP) in the United States, for example, grew at an annualized rate of 5.50% in the first quarter of 2006, while rising commodity and energy prices appeared to be adding to inflationary pressures. The fear of rising inflation added a measure of volatility to the fixed-income markets, especially affecting Treasuries and other high-quality, interest-rate sensitive sectors. The volatility intensified late in the fiscal year, as Treasury rates rose. At the same time, the U.S. dollar weakened against most major foreign currencies. In the first four months of 2006, for example, the dollar lost 6% of its value relative to the euro. Emerging market debt outperformed domestic high-yield bonds, based upon the fundamental improvement in the economies of many developing nations that benefited from high commodity prices and the global economic expansion. High-yield corporate debt in foreign developed nations also did well, helped by weakness in the U.S. dollar and the growing investor appetite for higher yields. Q: How did you position the Fund in this environment? A: We emphasized domestic high-yield bonds over both emerging market debt and international high-yield debt. Although emerging market securities were performing well, we were concerned about their tight yield advantages over other fixed-income securities, and we did not believe investors were adequately compensated for the risks. Political risks were especially prominent in Latin America, where several countries were preparing for national elections that could affect the capital markets. We also believed that the sovereign debt of many emerging nations was over-valued. We tended to focus our emerging markets investments on good high-yield 5 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 4/30/06 (continued) - -------------------------------------------------------------------------------- companies whose debt was selling at discounts to the debt of comparable high-yield companies in the United States and Europe. We also emphasized investments in Asia, especially nations that were affected by the dynamic growth in China. At the end of the six-month period, 55.4% of Fund assets were invested in the domestic high-yield market, with 29.8% in emerging markets and 11.6% in international high yield. Average credit quality was B, as measured by credit rating agency Standard & Poor's, on April 30, 2006. Q: What strategies and investments had the greatest impact on investment results? A: Good security selection was the primary driver of performance, helping the Fund outperform its benchmarks despite our de-emphasis of the better-performing emerging market and foreign high-yield areas. Within our foreign allocations, we overweighted Norway, with a special emphasis on oil services companies that were positioned to benefit from the strong energy market. Bonds of oil services companies, such as Kvaerner, Sevan Marine and Thule Drilling all performed particularly well. Our heavier relative position in the bonds of basic materials companies in general also helped Fund results as these companies gained with rising commodity markets. We also had established positions in the bonds of several companies that subsequently announced that they were being acquired or restructuring their finances by issuing initial public stock offerings. Bonds that appreciated in value as companies announced they were being acquired included securities of: Indo Coal, an Indonesian coal company; Doane Pet Care, a pet food company; and Stone Energy, an oil and gas producer. Hexion Specialty Chemicals (Resolution Performance), another company whose bonds we held, announced it intended to issue a new stock offering and bought back its bonds. Performance also received a boost when Navistar, the truck manufacturer, was forced to buy back its debt because it was late in filing financial statements. Our holdings in airline industry bonds helped Fund performance, as securities issued by Continental and AMR, parent of American Airlines, appreciated as the industry gained improved pricing power. Other successful investments included securities of chemical 6 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- company Celanese and of Pegasus Solutions, which provides an automated reservations system for the hospitality industry. Our underweight position in foreign currencies held back performance during a period in which the dollar weakened. Also detracting from results were our positions in several companies that ran into difficulties, although none defaulted on their debt. Mandra Forestry, a Chinese company, had disappointing results because of greater-than-expected harvesting costs. School bus operator Atlantic Express, another disappointment, was affected by rising fuel costs. While many holdings benefited from the growing economy, Stanadyne was an exception. This manufacturer of filters for construction machinery and tractors had difficulty keeping up with growing demand for its products. As it spent more money to increase its production, its profit margins declined. Q: What is your investment outlook? A: As a consequence of the combination of higher interest rates and rising commodity prices, we anticipate a slowing from the relatively torrid pace of global economic growth that we have witnessed during the past two years. As rates have risen, we have become more cautious and reduced the Fund's sensitivity to interest rates by shortening duration, a measure of a bond's price sensitivity to changes in interest rates. On April 30, 2006, for example, the Fund's effective duration was 4.2 years. This short duration also gives us the flexibility to re-invest in attractive opportunities as they appear. We anticipate that we shall continue to be underweighted in emerging markets, where we think valuations do not justify the risks of the asset class. Although we are concerned about weakness in the dollar, we have not found many foreign bonds with valuations that would justify our investment. We expect to maintain an emphasis on the U.S. high-yield market, where corporations are in generally solid financial shape. In the domestic market, we seek to find the most attractive yields and values relative to other fixed-income asset classes. 7 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 4/30/06 (continued) - -------------------------------------------------------------------------------- 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. Investing in foreign and/or emerging markets securities involves risks relating to interest rates, currency exchange rates, economic, and political conditions. 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. Prepayment risk is the chance that mortgage-backed bonds will be paid off early if falling interest rates prompt homeowners to refinance their mortgages. Forced to reinvest the unanticipated proceeds at lower interest rates, the Fund would experience a decline in income and lose the opportunity for additional price appreciation associated with falling interest rates. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. These risks may increase share price volatility.

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.

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.

Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 4/30/06 (unaudited) - -------------------------------------------------------------------------------- 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 four classes of shares - Class A, Class B, Class C shares and Class Y shares. Class Y shares were first publicly offered on December 28, 2005. Each class of shares represents an interest in the same portfolio of investments of the Fund and has 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, Class C, and Class Y shareowners, respectively. There is no distribution plan for Class Y shares. Class B shares convert to Class A shares eight years after the date of purchase. 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: 39 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 4/30/06 (unaudited) (continued) - -------------------------------------------------------------------------------- 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 they are traded. Fixed income securities with remaining maturity of more than 60 days are valued at prices supplied by independent pricing services, which consider such factors as Treasury spreads, yields, maturities and ratings. Valuations may be supplemented by dealers and other sources, as required. Securities for which there are no other readily available valuation methods 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 accurately reflects the value of the security. Temporary cash investments are valued at amortized cost. All 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 40 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. Information regarding the Fund's principal risk is contained in the Fund's prospectus. Please refer to these documents when considering the Fund's risks. 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. 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. 41 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 4/30/06 (unaudited) (continued) - -------------------------------------------------------------------------------- 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, 2006, 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 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, 2005 was as follows: - -------------------------------------------------------------------------------- 2005 - -------------------------------------------------------------------------------- Distributions paid from: Ordinary income $ 35,694,337 Long-term capital gain - ------------ Total $ 35,694,337 ============ - -------------------------------------------------------------------------------- 42 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- The following shows the components of distributable earnings on a federal income tax basis at October 31, 2005: - -------------------------------------------------------------------------------- 2005 - -------------------------------------------------------------------------------- Undistributed ordinary income $ 2,825,576 Undistributed long-term gain 2,101,843 Dividend payable (2,128,749) Unrealized appreciation (6,920,819) ----------- Total $(4,122,149) =========== - -------------------------------------------------------------------------------- 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 $139,146 in underwriting commissions on the sale of Class A shares during the year ended April 30, 2006. 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 43 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 4/30/06 (unaudited) (continued) - -------------------------------------------------------------------------------- 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 sponsored 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. Effective 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 the Fund expenses to 1.10%, 2.00% and 2.00% of the average daily net assets attributable to Class A, Class B and Class C shares, respectively. These expense limitations are in effect through March 1, 2008 for Class A shares and through March 1, 2006 for Class B and Class C 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, 44 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 2006, $49,331 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 $28,028 in transfer agent fees receivable from PIMSS at April 30, 2006. 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 services or distribution services with regard to Class B and Class C shares. Included in due to affiliates is $301,566 in distribution fees payable to PFD at April 30, 2006. In addition, redemptions of each class 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. Shares purchased prior to December 1, 2004, remain subject to the CDSC in effect at the time those shares were purchased. Shares purchased as part of an exchange or acquired as a result of a reorganization of another fund into the Fund remain subject to any contingent deferred sales charge that applied to the shares you originally purchased. Redemptions of 45 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 4/30/06 (unaudited) (continued) - -------------------------------------------------------------------------------- Class C shares within one year of purchase are subject to a CDSC of 1.00%. Proceeds from the CDSCs are paid to PFD. For the year ended April 30, 2006, CDSCs in the amount of $221,989 were paid to PFD. Effective March 2, 2004, the Fund charges a 2.00% redemption fee on Class A, Class B, and Class C shares redeemed within 30 days of purchase. The fee does not apply to certain types of transactions as described in the Fund's prospectus. For the year ended April 30, 2006, the Fund collected $15,584 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 year ended April 30, 2006, the Fund's expenses were reduced by $9,370 under such arrangements. 46 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 an index, 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 Fund's investment policies and 47 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- FACTORS CONSIDERED BY THE INDEPENDENT TRUSTEES IN APPROVING THE MANAGEMENT CONTRACT (continued) - -------------------------------------------------------------------------------- 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 year 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, break points in the management fee for the Fund and a peer group selected by the Independent Trustees for this purpose and certain of the Fund's expenses that are not incurred as fees based on a percentage of net assets. The following summarizes factors considered by the Trustees in connection with reviewing the information described above and 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 48 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- large number of investment companies offering a variety of 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, 2005 and the first quintile for the three years ended June 30, 2005. (In all quintile rankings referred to throughout this discussion first quintile is most favorable to the Fund's shareholders. Thus, highest relative performance would be first quintile and lowest relative expenses also would be first quintile.) The Trustees also considered the yield (gross of expenses) on the class A shares of the Fund relative to the yield (as of June 30, 2005) on the Merrill Lynch Global High Yield and EMP Index. 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 fixed income group. Among other things, the Trustees considered the number, education and experience of the Investment Adviser's investment staff and their use of technology and emphasis on analytics in view of the risk profile of securities in which the 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. 49 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- FACTORS CONSIDERED BY THE INDEPENDENT TRUSTEES IN APPROVING THE MANAGEMENT CONTRACT (continued) - -------------------------------------------------------------------------------- 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 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, 2005 was in the fourth 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 for the 12 months ended June 30, 2005 was in the first quintile (after expense limitations) relative to the expense ratios paid by other funds in that peer group for that comparable period. The Trustees concluded that the Fund's overall expense ratio was reasonable compared to the expense ratios of similar funds. F. Profitability. The Trustees considered the level of the Investment Adviser's profits with respect to the management of the Pioneer Funds, including details with respect to the Fund. This 50 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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 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). 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. 51 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- FACTORS CONSIDERED BY THE INDEPENDENT TRUSTEES IN APPROVING THE MANAGEMENT CONTRACT (continued) - -------------------------------------------------------------------------------- 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. 52 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- TRUSTEES, OFFICERS AND SERVICE PROVIDERS - -------------------------------------------------------------------------------- Trustees Officers John F.

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.
