Uncertainty over war in Iraq brought steep declines in equities and a continued flight to bonds, especially government issues. Stocks rallied when the war began, sagged for a time, then rose modestly as the successful military campaign wound down. Investors soon turned their attention to domestic concerns, not all of them tied to the war: sagging consumer confidence, rising unemployment made worse by call-ups of reservists and the uncertain outlook for corporate earnings. In addition, a long, harsh winter hampered economic activity, as did the high prices Americans were paying to power their cars, homes and businesses. The Federal Reserve Board appears committed to keeping interest rates low to prevent the economy from slumping further. A weaker U.S. dollar may also act as a stimulus, as American export goods become more affordable for overseas buyers. Independent research remains the key Pioneer is not in the business of forecasting economic trends or predicting geopolitical events. Our focus remains, as it has for over 75 years, on intensive analysis of hundreds of companies to find the best values for our shareowners; this slow economic period has brought many valuations to what we believe are attractive levels. Our managers and analysts are concentrating on companies with demonstrably strong finances and positive prospects. Financially strong companies have greater potential to prosper when the economy eventually rights itself. Pioneer's fixed-income experts are also finding bonds, both here and overseas, that offer good current yields and the potential for higher prices. Consult a trusted advisor It's tempting to change course in turbulent times while world news dominates our consciousness. But timing the market - moving in and out with short-term factors - - can be costly in terms of lost opportunities; there's no predicting when a rebound might begin. You can temper that risk by relying on dispassionate professional advice. So invest the time it takes to meet with a trusted financial advisor who brings the dual advantages of knowledge and experience to the table. All of us at Pioneer thank you for your continued business. Respectfully, /s/ John A. Carey John A. Carey Executive Vice President, Pioneer Investment Management, Inc.

The ML Global High Yield & Emerging Markets Plus Index tracks the performance of the below- and border-line investment-grade global debt markets denominated in the major developed market currencies. The Index includes sovereign issuers rated BBB1 and lower along with corporate issuers rated BB1 and lower. There are no restrictions on issuer country of domicile. However, the bonds must be publicly issued in a developed market (i.e., investment-grade country). Index returns are calculated monthly, assume reinvestment of dividends and, unlike Fund returns, do not reflect any fees, expenses or sales charges. You cannot invest directly in the Index. Past performance does not guarantee future results. Returns and principal value fluctuate and your shares, when redeemed, may be worth more or less than their original cost. The performance table and graph do not reflect the deduction of taxes that a shareowner would pay on Fund distributions or the redemption of Fund shares. 3 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 4/30/03 - -------------------------------------------------------------------------------- Investors enjoyed soaring returns from high-yield markets throughout the world. These markets for lower-rated bonds were spurred by a significant interest rate cut by the U.S. Federal Reserve and improving conditions in Europe and in emerging markets. 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 economic environment during the six-month period. Q: How did the Fund perform? A: The Fund had extremely strong performance. For the six-month period ended April 30, 2003, the Fund's Class A shares had a total return of 30.50% at net asset value. During the same period, the Merrill Lynch Global High Yield and Emerging Markets Plus Index returned 30.36%. The Merrill Lynch High Yield Master Index, which reflects the performance only of the U.S. high-yield market, rose 22.21%. Q: What factors led to such strong performance? A: Virtually all the markets in which we invested performed very well, underscoring the types of opportunities that can be offered by a global high-yield strategy. These markets had just finished a difficult period caused by rising geopolitical risks and sluggish economic growth throughout the world as well as corporate governance and accounting controversies in the United States. That challenging environment changed in November 2002, however, starting with the decision of the U.S. Federal Reserve to lower short-term interest rates by a surprising one-half of one percentage point. That helped inject new liquidity into credit markets, and high-yield bond prices began to recover. The relatively quick resolution of the war in Iraq later in the period added to the sense of increased confidence in corporate bond markets. Other factors contributed to growing confidence in overseas high-yield markets. In Europe, highly competitive yields and a strengthening currency combined to attract investors. In many instances, one could find a bond in Europe identical to a bond in the United States, but with a significant yield premium over the U.S. security. The European market, the world's fastest growing high-yield market, has emerged as an area where careful credit analysis can lead to the discovery of mispriced and undervalued bonds. 4 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- Emerging markets continued to recover during the period. One factor in the improving environment was the emergence of a new government in Brazil, an influential market that had been a concern earlier. Investors had worried that the new president would be ideologically anti-business. However, after he took office, President Lula Da Silva continued the previous administration's pro-market policies. Q: How did your strategies affect performance during the period? A: As a global investment company specializing in independent analysis of different securities, Pioneer was able to find bonds of many good companies trading at extremely attractive prices. Our emphasis on foreign currencies and the U.S. high-yield market gave substantial support to performance during the period. We had slightly overweighted the euro, significantly overweighted the Canadian dollar, and also emphasized the South African rand. All three currencies gained significantly against the U.S. dollar. We also had emphasized domestic high-yield bonds over emerging market debt, based on our analysis of relative values. In addition, we found the bonds of many U.S. corporations trading at extremely attractive values, and they appreciated strongly over the period. Later in the period, we began to take advantage of the strong performance of many holdings to take profits and upgrade the overall credit quality of the portfolio. We looked for opportunities to move from riskier to less risky assets where valuations make sense. In addition, while we thought the U.S. dollar might continue to be weak relative to other currencies, we started to decrease our overweight positions in non-dollar currencies such as the euro and the South African rand. We also have reduced our holdings in Russian securities, which had been our largest emerging market position at the beginning of the period. Our Russian holdings had appreciated strongly during the period, and we saw less potential for future gains in those investments. Over the full six months, our regional allocations did not change significantly. On April 30, 2003, 63% of Fund assets were invested in the United States and Canada, 23% in emerging markets, and 14% in other foreign high-yield bonds, mostly in Europe. 5 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 4/30/03 (continued) - -------------------------------------------------------------------------------- Q: What specific investments most significantly influenced Fund performance? A: Our Russian investments turned in very favorable performance. The prices of Russian sovereign bonds rose from $76 to $90 (based on $100 price at face value). MTS, a Russian cell phone operator in the Moscow area, also performed well. In Canada, the bonds of Kinross Gold appreciated significantly, helped both by the rising price of gold and the strength of the Canadian dollar. Other significant non-U.S. investments that helped performance were the European bonds of Huntsman International and the securities of PTC Financial, a Polish cell phone company that is rapidly paying down debt. Among the better-performing U.S. investments were: Xerox, whose bonds gained after a new management team restructured the company's finances; Freeport-McMoRan, a copper and mining company with an extraordinarily productive mine property; Juniper Networks, the developer of equipment for communications networks; and Tesoro, a refiner that benefited both from higher energy prices and improving prospects of its customers in the chemical industry. Even in a very good performance period, we did have some disappointments, however. The bonds of Durango, a Mexican paper company, fell late in 2002 when inventory problems caused them to miss a December debt payment and later default on their outstanding debt. In the United States, Indianapolis Airport Facility Bonds fell when United Airlines, a major tenant at the airport, filed for bankruptcy and indicated it no longer planned to use a repair facility in Indianapolis. Q: What is your investment outlook? A: Using our value-oriented discipline, we are continuing to find many opportunities. In Europe, for example, we have discovered a number of mispriced bonds that offer very strong performance potential. Looking at broad macroeconomic trends, we also believe the markets should be less volatile than they have been in recent months. As the general growth environment stabilizes, high-yield investments should stand to benefit. At the same time, returns from those investments are likely to be less impressive than they were over the past six months. 6 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- SCHEDULE OF INVESTMENTS 4/30/03 (unaudited) - -------------------------------------------------------------------------------- Principal Amount Value CONVERTIBLE CORPORATE BONDS - 17.3% Materials - 3.2% Precious Metals & Minerals - 3.2% $ 40,000 Kinross Gold, 5.5%, 12/5/06 $ 25,314 -------- Total Materials $ 25,314 -------- Consumer Durables & Apparel - 1.7% Leisure Products - 1.7% 15,000 Aristocrat Leisure, Ltd., 5.0%, 5/31/06 $ 13,519 -------- Total Consumer Durables & Apparel $ 13,519 -------- Pharmaceuticals & Biotechnology - 5.2% Biotechnology - 1.0% 10,000 Human Genome, 3.75%, 3/15/07 $ 7,712 -------- Pharmaceuticals - 4.2% 10,000 Cubist Pharmaceuticals, 5.5%, 11/1/08 $ 7,113 20,000 IVAX Corp., 4.5%, 5/15/08 18,525 10,000 Vertex Pharmaceuticals Inc., 5.0%, 9/19/07 8,137 -------- $ 33,775 -------- Total Pharmaceuticals & Biotechnology $ 41,487 -------- Technology Hardware & Equipment - 3.3% Networking Equipment - 2.3% 20,000 Juniper Networks Inc., 4.75%, 3/15/07 $ 18,100 -------- Semiconductors - 1.0% 10,000 Triquint Semiconductor, 4.0%, 3/1/07 $ 8,325 -------- Total Technology Hardware & Equipment $ 26,425 -------- Telecommunication Services - 3.9% Integrated Telecommunication Services - 1.3% 22,000 Colt Telecom Group, 2.0%, 8/6/05 $ 9,810 -------- Wireless Telecommunication Services - 2.6% 25,000 Nortel Networks, 4.25%, 9/1/08 $ 20,844 -------- Total Telecommunication Services $ 30,654 -------- TOTAL CONVERTIBLE CORPORATE BONDS (Cost $121,901) $137,399 -------- The accompanying notes are an integral part of these financial statements. 7 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- SCHEDULE OF INVESTMENTS 4/30/03 (unaudited) (continued) - -------------------------------------------------------------------------------- Principal Amount Value CORPORATE BONDS - 66.4% Materials - 18.6% Construction Materials - 2.7% $ 20,000 Hexcel Corp., 9.875%, 10/1/08 (144A) $ 21,400 -------- Diversified Chemicals - 2.7% 20,000 Huntsman ICI Chemicals LLC, 10.125%, 7/1/09 $ 21,698 -------- Diversified Metals & Mining - 3.4% 25,000 Freeport-McMoRan Copper & Gold, 10.125%, 2/1/10 (144A) $ 27,062 -------- Metal & Glass Containers - 1.5% 10,000 Crown Euro Holdings SA, 10.25%, 3/1/11 (144A) $ 11,632 -------- Paper Packaging - 1.9% 15,000 FiberMark Inc., 10.75%, 4/15/11 (144A) $ 15,150 -------- Paper Products - 0.6% 10,000 Corp Durango SA de CV, 13.125%, 8/1/06 (d) $ 4,950 -------- Specialty Chemicals - 5.8% 15,000 Arco Chemical Co., 9.8%, 2/1/20 $ 14,250 15,000 Ethyl Corp., 8.875%, 5/1/10 (144A) 15,600 15,000 United Industries Co., 9.875%, 4/1/09 (144A) 15,900 -------- $ 45,750 -------- Total Materials $147,642 -------- Capital Goods - 3.4% Industrial Machinery - 3.4% 25,000 NMHG Holding Co., 10.0%, 5/15/09 $ 26,750 -------- Total Capital Goods $ 26,750 -------- Commercial Services & Supplies - 3.7% Diversified Commercial Services - 1.1% 10,000 Wesco Distribution Inc., 9.125%, 6/1/08 $ 9,000 -------- Environmental Services - 2.6% 20,000 IESI Corp., 10.25%, 6/15/12 $ 20,700 -------- Total Commercial Services & Supplies $ 29,700 -------- Automobiles & Components - 1.3% Auto Parts & Equipment - 1.3% 10,000 Collins & Aikman Products, 10.75%, 12/31/11 $ 10,250 -------- Total Automobiles & Components $ 10,250 -------- 8 The accompanying notes are an integral part of these financial statements.

Organization and Significant Accounting Policies Pioneer Global High Yield Fund (the Fund), is a Delaware business trust, registered under the Investment Company Act of 1940 as a non-diversified, open-end management investment company. The Fund was organized on May 5, 2001 and commenced operations on August 27, 2001. Prior to August 27, 2001 the Fund had no operations other than those relating to organizational matters and the initial capitalization of the Fund by Pioneer Funds Distributor, Inc. (PFD). To date, no shares have been offered to the public. The Fund shares outstanding at April 30, 2003 are owned by PFD. The investment objective of the Fund is to maximize total return through a combination of income and capital appreciation. The Fund's financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America that require the management of the Fund to, among other things, make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. The following is a summary of significant accounting policies consistently followed by the Fund, which are in conformity with those generally accepted in the investment company industry: A. Security Valuation Security transactions are recorded as of trade date. Securities are valued at prices supplied by independent pricing services, which consider such factors as Treasury spreads, yields, maturities and ratings. Valuations may be supplemented by dealers and other sources, as required. Securities for which market quotations are not readily available are valued at their fair values as determined by, or under the direction of, the Board of Trustees and may include yield equivalents or a pricing matrix. Market discounts and premiums are accreted or amortized daily on a yield-to-maturity basis. Original issue discount is accreted daily into interest income on a yield-to-maturity basis with a corresponding increase in the cost basis of the security. Interest income, including interest on income bearing cash accounts, is recorded on the accrual basis, net of unrecoverable foreign taxes withheld at the applicable country rates. Temporary cash investments are valued at amortized cost. 16 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. The Fund invests in below investment grade (high yield) debt securities and preferred stocks. These high yield securities may be convertible into equity securities of the issuer. Debt securities rated below investment grade are commonly referred to as "junk bonds" and are considered speculative. These securities involve greater risk of loss, are subject to greater price volatility, and are less liquid, especially during periods of economic uncertainty or change, than higher rated debt securities. The Fund is not diversified, which means that it can invest a higher percentage of its assets in any one issuer than a diversified fund. Being non-diversified may magnify the Fund's losses from adverse events affecting a particular issuer. 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. dollar 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 17 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 4/03/03 (unaudited) (continued) - -------------------------------------------------------------------------------- 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, 2003, the Fund had no outstanding portfolio or settlement hedges. D. Federal Income Taxes It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income and net realized capital gains, if any, to its shareowners. Therefore, no federal income tax provision is required. The characterization of distributions to shareowners for financial reporting purposes is determined in accordance with federal income tax rules. Therefore, the source of the Fund's distributions may be shown in the accompanying financial statements as either from or in excess of net investment income or net realized gain on investment transactions, or from paid-in capital, depending on the type of book/tax differences that may exist. E. Fund Shares The Fund records sales and repurchases of its shares as of trade date. PFD, the principal underwriter for the Fund and a wholly owned indirect subsidiary of UniCredito Italiano S.p.A. (UniCredito Italiano), earned no underwriting commissions on the sale of Fund shares during the six months ended April 30, 2003. F. Security Lending The Fund lends securities in its portfolio to certain broker-dealers or other institutional investors, with the Fund's custodian acting as the lending agent. When entering into a loan, the Fund receives collateral, which is maintained by the custodian and earns income in the form of negotiated lenders' fees. The Fund also continues to receive interest or dividends on the securities loaned, and gain or loss in the fair value of the loaned securities that may occur during the term of the loan will be for account of the Fund. The loans are secured by collateral of at least 102%, at all times, of the fair value of the securities loaned. The fair value of collateral will be adjusted daily to 18 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- reflect any price fluctuation in the value of the loaned securities. The value of loaned securities and cash collateral at period end are disclosed on the balance sheet. The Fund invests cash collateral in the Securities Lending Investment Fund, which is managed by Brown Brothers Harriman & Co., the Fund's custodian. 2. Management Agreement Pioneer Investment Management, Inc. (PIM), the Fund's investment adviser, manages the Fund's portfolio and is a wholly owned indirect subsidiary of UniCredito Italiano. Management fees are calculated daily at the annual rate of 0.70% of the Fund's average daily net assets up to $500 million; 0.65% of the next $500 million; and 0.60% on the assets over $1 billion. PIM has agreed not to impose all or portion of its management fee and to assume other operating expenses of the Fund to the extent necessary to limit expenses to 0.75% of the Fund's average daily net assets. 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, 2003, $2,954 was payable to PIM related to management fees, administrative fees and certain other services. 3. Transfer Agent Pioneer Investment Management Shareholder Services, Inc. (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 $385 in transfer agent fees payable to PIMSS at April 30, 2003. 4. Distribution Plans The Fund adopted a plan of distribution for Class A shares in accordance with Rule 12b-1 under 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. Included in due to affiliates is $173 in distribution fees payable to PFD at April 30, 2003. 19 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- TRUSTEES, OFFICERS AND SERVICE PROVIDERS - -------------------------------------------------------------------------------- Trustees Officers John F.
