The Fund, introduced to investors on December 28, 2007, offers investors the opportunity to receive current income from a prudently managed portfolio of investment-grade, fixed-income securities from the world's industrialized nations. The Fund draws upon Pioneer's international reach as well as its demonstrated expertise in investing in fixed-income markets around the globe. The experiences in the world's capital markets during the first four months of 2008 reinforce the importance of two general investment themes: stay diversified and keep your portfolio invested in the markets. These are principles that have served investors well over time. They are particularly useful guides to keep in mind today, at a time when markets around the globe are being buffeted by problems in the financial and real estate industries and by concerns about a slowing economy. After an extended period of steady economic growth with sustained low unemployment and low inflation, the U.S. economy ran into difficulty as 2007 drew to a close. Investors in subprime mortgages were forced to mark down the value of their assets, imperiling leveraged balance sheets. The ensuing credit crunch forced central banks in the United States and Europe to assume the role of "lender of last resort" to keep credit markets functioning. Conditions worsened in the first quarter of 2008, as falling prices, margin calls and deleveraging continued, the auction rate preferred market seized up. The U.S. Federal Reserve expanded its lender-of-last-resort role to include lending to primary dealers and continued to cut interest rates. By then, recession talk was widespread as concern grew that falling home prices, rising unemployment, sharply rising food and energy prices, and disruptions in financial markets posed a significant threat to economic growth. Markets reacted poorly to the developments leading up to the problems at Bear Stearns, with fixed-income credit spreads (the difference in rates between corporate and U.S. government bonds) widening dramatically and stock markets declining, wiping out the positive returns markets had delivered in the preceding calendar year. Treasury bond prices rose as the market underwent a flight to quality. In the six weeks between the near failure of Bear Stearns and the end of April, though, there were no further market crises, recession fears faded in light of positive economic news, and stock markets rallied, recouping some of their first-quarter losses, while Treasury bond prices fell back. Over the four months ending April 30, 2008, the U.S. investment-grade bond market, as measured by the Lehman Brothers Aggregate Bond Index, 2 Letter rose 1.95%. Over the same period, the Lehman Brothers Global Aggregate Bond, a reflection of investment-grade bond performance throughout the world, gained 4.60%. The U.S. high-yield bond market, as measured by the Merrill Lynch High Yield Bond Master II Index, rose 1% over the four months ending April 30, 2008. Also during the period, the Merrill Lynch Global High Yield and Emerging Markets Plus Index, which reflects the performance of high-yield corporate bonds and emerging market securities globally, gained 1.73%. Looking forward, the risk of a 2008 recession seems diminished, but substantial risks remain in both financial markets and the real economy. On the other hand, a weak U.S. dollar and substantial fiscal and monetary stimulus are potent support for the economy. Markets remain volatile, and falling risk tolerances and deleveraging may depress asset prices in the short term, but equity and corporate bond valuations look attractive over a longer time horizon unless the U.S. economy falls into a severe and protracted recession. Sudden swings in the markets are always to be expected, but they are difficult to time. Maintaining a long-term time horizon, being diversified, and paying attention to asset allocation are important investment principles. As always, we encourage you to work closely with your financial advisor to find the mix of stocks, bonds and money market assets that is best aligned to your particular risk tolerance and investment objective and to adhere to a strategic plan rather than letting emotion drive investment decisions.

Investment-grade corporate securities trailed the performance of government bonds, especially in the first three months of the year, as the yield spreads between high-grade and lower-rated securities widened. The following is an interview with Charles Melchreit, a member of the team that managed Pioneer Global Aggregate Bond Fund from its inception on December 28, 2007, through the end of the Fund's first reporting period on April 30, 2008. Q: How did the Fund perform since the start of its operations on December 28, 2007, through April 30, 2008? A: Pioneer Global Aggregate Bond Fund's Class A shares had a total return of 4.02% at net asset value during the period, while during the same period the Lehman Global Aggregate Bond Index returned 4.60% and the Lehman Aggregate Bond Index rose by 1.95%. During the first four months of 2008, the average return of the 125 mutual funds in Lipper's Global Income category was 2.55%. On April 30, 2008, the Fund's 30-day SEC yield for Class A shares was 2.71%. 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 main factors affecting performance during the four-month period ended April 30, 2008? A: In a challenging global investment environment, our focus on the sovereign debt in Europe and U.S. government agencies helped the Fund hold up well against a volatile backdrop. The Fund began investing in the midst of a global credit crisis. The turmoil that began with concerns about U.S. subprime mortgage problems created a loss of financial liquidity in credit markets generally, causing a drying up of money available for lending. Banks in Europe and Japan as well as in the United States announced significant losses as they reported massive write-downs in the 4 Pioneer Global Aggregate Bond Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- values of subprime-related loans carried on their balance sheets. The turmoil in the financials sector raised concerns about the sustainability of economic growth trends, most notably in the United States, the United Kingdom and Europe. The U.S. economy showed the greatest weakness, while the strength of foreign markets helped sustain strong global growth trends overall. In this environment, credit spreads widened, indicating the growing yield differences between high-quality and lower-quality debt, with the highest-quality securities turning in the best relative results. Investment-grade corporate bonds were among the groups affected adversely, while U.S. Treasuries, government-backed mortgages and sovereign government bonds performed relatively well. Q: What were your principal strategies in this environment? A: Pioneer Global Aggregate Bond Fund is designed to invest in high-quality debt securities, focused on opportunities in developed, industrialized economies. The Fund emphasizes investments in investment-grade corporate bonds, government-agency securities and the sovereign debt of governments of industrialized nations. As we began investing, the market offered little incentive to move outside this principal investment universe and the Fund avoided investing in emerging markets. The Fund saw the greatest opportunities in the United States, where asset values in corporate bonds and mortgage-backed securities had fallen to relatively attractive levels as a result of the credit crisis. We invested in bonds of financials and industrial companies and both U.S. agency and non-agency mortgage-backed securities. Outside the United States, the Fund focused primarily in government bonds, investing in Europe, the United Kingdom and Japan. In Europe, the Fund were concerned about a slowing of the economy and downplayed corporate investments, although the Fund did invest selectively in some financials sector bonds that had been underperforming. However, in the United Kingdom, concerns about the health of the financials sector and weakness in housing caused the Fund largely to avoid investments in financials sector bonds. In the Fund's currency allocations, the Fund emphasized U.S. dollar-linked currencies, including those of the United States, Canada, Australia and New Zealand. Together, they constituted approximately 55% of the Fund's assets at the end of the period on April 30, 5 Pioneer Global Aggregate Bond Fund - -------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 4/30/08 (continued) - -------------------------------------------------------------------------------- 2008. The Fund was underweighted in both the euro and euro-bloc currencies as well as the British pound sterling. Relative to the Lehman Global Aggregate Bond Index, the Fund was significantly underweighted in the Japanese yen, primarily because of unattractive yields. At the end of the period, on April 30, 2008, 28.2% of the Fund's assets were invested in U.S. mortgage-backed securities, 14.4% were invested in investment-grade bonds in the United States, 9.2% were invested in U.S. Treasury and government agency bonds, and 12.3% were invested in cash and short-term equivalents. Approximately 34% of the Fund's assets were invested in developed markets, primarily in government securities. The Fund had minimal exposure to high-yield corporate bonds or emerging market debt. Average credit quality of the Fund's portfolio was AA, while the average maturity of the Fund's holdings was 6.3 years and average effective duration was 4.4 years. Q: What types of investments most influenced performance? A: Security selection in the United States and in Europe helped support results. The Fund's positions in European sovereign debt and in U.S. government agency mortgages proved to be particularly successful. Holding back results was the Fund's underweighting of the Japanese yen, which rallied against other currencies during the period. In addition, the relatively short duration of the Fund's portfolio in its investments in the United States held back relative results, as intermediate-term securities outperformed as interest rates declined. Q: What is your investment outlook? A: We believe attractive value still exists in the United States, particularly in investment-grade corporates. The valuations of many bonds have been beaten down by the negative environment for credit-sensitive securities, especially in relation to our outlook for the overall economy. We think that while the economy is slowing, we are not likely to see a severe recession. Banks, with the help of the monetary stimulus supplied by the Federal Reserve, should be able to repair the damage to their balance sheets caused by the credit crisis. Despite weakness in housing and the financials 6 Pioneer Global Aggregate Bond Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- sector, we think the economy should be able to hold up, growing slowly this year and then accelerating in 2009. In the near term, we think the U.S. dollar may appreciate against foreign currencies, especially the British pound sterling and eurozone currencies. We anticipate holding investments with a longer duration in the Europe and in the United Kingdom, as we think their central banks are likely to lower short-term rates in the coming months. We also expect to maintain investments with longer durations within the United States, which should be beneficial if market interest rates decline and prices rise. 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. The Fund can invest in a limited number of securities and, as a result, the Fund's performance may be more volatile than the performance of other funds holding more securities. 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. 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 Aggregate Bond Fund Based on actual returns from December 28, 2007 through April 30, 2008.

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.

Pioneer Global Aggregate Bond Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 4/30/08 (unaudited) - -------------------------------------------------------------------------------- 1. Organization and Significant Accounting Policies Pioneer Global Aggregate Bond Fund (the Fund) is a series of Pioneer Series Trust VII, a Delaware statutory trust registered under the Investment Company Act of 1940 as a non-diversified, open-end management investment company. 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 C, and Class Y shares. Class A, Class C, and Class Y shares were first publicly offered on December 28, 2007. 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 and Class C shareowners, respectively. There is no distribution plan for Class Y shares. 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 year. Actual results could differ from those estimates. 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. 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. The Fund's prospectuses contain information regarding the Fund's principal risks. Please refer to those documents when considering the Fund's risks. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements, which are 33 Pioneer Global Aggregate Bond Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 4/30/08 (unaudited) (continued) - -------------------------------------------------------------------------------- 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 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 using fair value methods pursuant to procedures adopted by the Board of Trustees. At April 30, 2008 there were no securities that were valued using fair value methods. Temporary cash investments are valued at cost which approximates market value. 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. 34 Pioneer Global Aggregate Bond Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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, if any, 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. (See Note 6) 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 35 Pioneer Global Aggregate Bond Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 4/30/08 (unaudited) (continued) - -------------------------------------------------------------------------------- distributions may be shown in the accompanying financial statements as from or in excess of net investment income or as from net realized gain on investment transactions, or as 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. E. Fund Shares The Fund records sales and repurchases of its shares as of trade date. Pioneer Funds Distributor, Inc. (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 Class A shares during the period ended April 30, 2008. F. Class Allocations 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. Distribution fees are calculated based on the average daily net asset value attributable to Class A and Class C of the Fund, respectively (see Note 4). Class Y shares are not subject to a distribution plan. Shareowners of each class participate in 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). 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 C and Class Y shares can bear different transfer agent and distribution expense rates. 36 Pioneer Global Aggregate Bond Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- G. Securities Lending The Fund lends securities in its portfolio to certain broker-dealers or other institutional investors. When entering into a loan, the Fund receives collateral 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 which is required to be at least 102%, at all times, of the fair value of the securities loaned. The amount of collateral is required to 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 cash equivalent investments. 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 0.50% of the Fund's average daily net assets. 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 1.00% and 1.90% of the average daily net assets attributable to Class A and Class C shares, respectively. These expense limitations are in effect through March 1, 2011 for Class A shares and through March 1, 2009 for 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. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $6 in management fees, administrative costs and certain other services payable to PIM at April 30, 2008. 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" reflected 37 Pioneer Global Aggregate Bond Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 4/30/08 (unaudited) (continued) - -------------------------------------------------------------------------------- on the Statement of Assets and Liabilities is $163 in transfer agent fees payable from PIMSS at April 30, 2008. 4. Distribution Plan 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 Plan, the Fund pays PFD 0.25% of the average daily net assets attributable to Class A shares as compensation for personal services and/or account maintenance services or distribution services with regard to Class A shares. Pursuant to the Plan, the Fund pays PFD 1.00% of the average daily net assets attributable to Class C shares. The fee for Class C shares 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 C shares. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $113 in distribution fees payable to PFD at April 30, 2008. In addition, redemptions of each class of shares (except Class Y) may be subject to a contingent deferred sales charge (CDSC). 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. Redemptions of Class C shares within one year of purchase are subject to a CDSC of 1.00% based on the lower of cost or market value of shares being redeemed. Proceeds from the CDSCs are paid to PFD. For the period ended April 30, 2008, no CDSCs were paid to PFD. 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 period ended April 30, 2008, the Fund's expenses were not reduced under such arrangements. 6. Forward Foreign Currency Contracts At April 30, 2008, the Fund had entered into various contracts that obligate the Fund to deliver currencies at specified future dates. At the maturity of a contract, the Fund must make delivery of the foreign currency. Alternatively, prior to the settlement date of a portfolio hedge, the Fund may close out such contracts by entering into an 38 Pioneer Global Aggregate Bond Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- offsetting hedge contract. Open Portfolio hedges at April 30, 2008 were as follows: - ------------------------------------------------------------------------------------------------------ Net Net Contracts to In Exchange Settlement Unrealized Currency (deliver)/receive For Date Value Gain (loss) - ------------------------------------------------------------------------------------------------------ GBP (British Pound Sterling) (50,000) (99,540) 5/7/08 $ (99,434) $ 106 JPY (Japanese Yen) (40,000,000) (391,428) 5/7/08 (384,920) 6,508 ------ $6,614 ====== - ------------------------------------------------------------------------------------------------------ At April 30, 2008, the Fund had no outstanding settlement hedges. 7. New Pronouncements In September 2006, Statement of Financial Accounting Standards No. 157, Fair Value Measurements (SFAS 157), was issued and is effective for fiscal years beginning after November 15, 2007. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Management is currently evaluating the impact the adoption of SFAS 157 will have on the Fund's financial statement disclosures. In March 2008, Statement of Financial Accounting Standards No. 161, Disclosures about Derivative Instruments and Hedging Activities ("SFAS 161"), was issued and is effective for fiscal years beginning after November 15, 2008. SFAS 161 requires enhanced disclosures about an entity's derivative and hedging activities. Management is currently evaluating the impact the adoption of SFAS 161 will have on the Fund's financial statement disclosures. 39 Pioneer Global Aggregate Bond Fund - -------------------------------------------------------------------------------- TRUSTEES, OFFICERS AND SERVICE PROVIDERS - -------------------------------------------------------------------------------- Trustees Officers John F.

They are particularly useful guides to keep in mind today, at a time when markets around the globe are being buffeted by problems in the financial and real estate industries and by concerns about a slowing economy. After an extended period of steady economic growth with sustained low unemployment and low inflation, the U.S. economy ran into difficulty as 2007 drew to a close. Investors in subprime mortgages were forced to mark down the value of their assets, imperiling leveraged balance sheets. The ensuing credit crunch forced central banks in the United States and Europe to assume the role of "lender of last resort" to keep credit markets functioning. Conditions worsened in the first quarter of 2008, as falling prices, margin calls and deleveraging continued, the auction-rate preferred market seized up. The U.S. Federal Reserve expanded its lender-of-last-resort role to include lending to primary dealers and continued to cut interest rates. By then, recession talk was widespread as concern grew that falling home prices, rising unemployment, sharply rising food and energy prices, and disruptions in financial markets posed a significant threat to economic growth. Markets reacted poorly to the developments leading up to the difficulties surrounding Bear Stearns, with fixed-income credit spreads (the difference in rates between corporate and U.S. government bonds) widening dramatically and stock markets declining, wiping out the positive returns markets had delivered in the preceding year. Treasury bond prices rose as the market underwent a flight to quality. In the six weeks between the Bear Stearns problems and the end of April, though, there were no further market crises, recession fears faded in light of positive economic news, and stock markets rallied, recouping some of their first-quarter losses, while Treasury bond prices fell back. Over the six-month period ending April 30, 2008, the Dow Jones Industrial Average fell 7%, the Standard & Poor's 500 Index fell 10% and the NASDAQ Composite Index fell 16%. The MSCI EAFE Developed Market Index of international stock markets fell 9%, and the MSCI Emerging Markets Index fell 10%. The U.S. investment-grade bond market, as measured by the Lehman Brothers Aggregate Bond Index, was a relatively solid performer over the six months, rising 4%. The U.S. high-yield bond market, as measured by the Merrill Lynch High Yield Bond Master II Index, fell 1% as its higher-coupon yields could not offset a fall in bond prices triggered by widening credit spreads. 2 Letter Looking forward, the risk of a 2008 recession seems diminished, but substantial risks remain in both financial markets and the real economy. On the other hand, a weak U.S. dollar and substantial fiscal and monetary stimulus should offer more support for the economy. Markets remain volatile, and falling risk tolerances and deleveraging may depress asset prices in the short term, but equity and corporate bond valuations look attractive over a longer time horizon unless the U.S. economy falls into a severe and protracted recession. Sudden swings in the markets are always to be expected, but they are difficult to time. Maintaining a long-term time horizon, being diversified, and paying attention to asset allocation are important investment principles. As always, we encourage you to work closely with your financial advisor to find the mix of stocks, bonds and money market assets that is best aligned to your particular risk tolerance and investment objective and to adhere to a strategic plan rather than letting emotion drive investment decisions.

Markets became increasingly volatile after a crisis that began in domestic subprime mortgages subsequently spread through the credit market. High-yield bonds staged a comeback in the final six weeks of the period, however, following the intervention of the U.S. Federal Reserve to inject more liquidity into financial markets and stabilize conditions. The following is an interview with Andrew Feltus, leader of the team managing Pioneer Global High Yield Fund. Mr. Feltus provides an update on the Fund and its investment strategies during the six months. Q: How did the Fund perform during the six months ending April 30, 2008? A: Pioneer Global High Yield Fund's Class A shares had a total return of -2.77%, at net asset value, over the six months. During the same period, the Merrill Lynch High Yield Master II Index declined by -0.77%, while the Merrill Lynch Global High Yield and Emerging Markets Plus Index rose 0.39%. The average return of the 458 mutual funds in Lipper's High Current Yield category was -2.22%. On April 30, 2008, the Fund's 30-day SEC yield for Class A shares was 9.78%.

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 was the investment environment like for high-yield bonds during the six months? A: Early in the period, high-yield bonds extended a comeback that began in October 2007 and continued through November, the period's first month, as we saw investors hoping for a stabilization following the sharp declines of the late summer and early fall. The declines were the result of problems originating in the U.S. subprime mortgage market that created fears about investment 4 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- quality, undermining values of credit-sensitive fixed-income sectors generally. The October-November comeback proved to be short-lived, however, as major investment banks throughout the world reported significant losses related to their exposure to subprime mortgages late in 2007. The announcements set the stage for rising concerns about credit quality in general, which led to significant underperformance by the most credit-sensitive parts of the fixed-income markets, including high-yield corporate bonds and asset-backed securities. In this period of uncertainty and growing market volatility, the U.S. Federal Reserve attempted to stabilize the markets by cutting the key Fed funds rate several times and initiating new policies intended to provide more money for lending activities. In a series of actions that started in September 2007 and continued through the end of April 2008, the Fed cut the Fed funds rate from 5.25% to 2.00%. In the final month, the Fed also helped arrange the rescue of the faltering investment bank Bear Stearns by JP Morgan Chase & Co. and opened up lending facilities to investment banks. The actions of the Federal Reserve led to a sharp comeback by higher yielding securities in the final six weeks of the period. As reflected by the Merrill Lynch High Yield Master II Index, the domestic high-yield bond market rose by about 6% in the final six weeks, although the revival was not enough to overcome the effects of losses in the middle of the six-month period. Foreign high-yield corporate bonds and emerging market debt generally performed in line with the domestic high-yield market during the six weeks, although higher-rated emerging market sovereign debt did somewhat better. Investments denominated in most foreign currencies also performed relatively well, as the U.S. dollar continued to weaken against most foreign currencies. Q: What were the principal factors that affected performance relative to the global high-yield market during the six months ending April 30, 2008? A: The Fund's emphasis on domestic high-yield bonds, which constituted 58.6% of assets at the end of the six months, tended to hold back results, as did our principal focus on corporate bonds, rather than sovereign debt, in emerging markets investments. On April 30, 2008, 27.2% of Fund assets were invested in emerging markets, mostly in corporate bonds. However, the Fund's exposure to securities denominated in other currencies tended to 5 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 4/30/08 (continued) - -------------------------------------------------------------------------------- help the Fund's results. We began the period with 9.4% of Fund assets invested in securities denominated in other currencies, but took profits during the six months and ended the period with a 7.9% foreign currency exposure. During a period in which the lowest-rated tiers of the high-yield universe, CCC and B, underperformed, our underexposure to CCC-rated securities helped somewhat, but that was offset by our emphasis on B-rated securities. While the Fund suffered no defaults, and we believe the Fund's high-yield holdings were fundamentally sound and justified our investments, the B-rated securities lagged because of the market's aversion to lower-rated securities. We continued to hold the investments based on our research of the underlying holdings and their potential to perform well over the longer term as market conditions stabilize. At the end of the fiscal period, the average credit rating of Fund holdings was B-. Q: What types of investments most influenced results during the six months ended April 30, 2008? A: The Fund's overweighted position in energy sector bonds among our domestic high-yield holdings helped results, as energy bonds generally performed very well amid rising oil and natural gas prices. While few individual lower-rated securities escaped the effects of the turmoil in credit markets, some individual holdings nevertheless did well. The holdings included bonds of Cell C, a South African telecommunications service company, and C&M Financial, a Korean cable communications corporation. Cell C reported improvement in its operations after earlier struggles, while both companies benefited from growing expectations that they might be acquired. In addition, bonds of TXU Energy, a Texas-based utility, rose during a period when utilities did well. The bonds were a result of a leveraged buyout during 2007. While leveraged buyouts generally fell out of favor, the strong asset values supporting TXU's bonds helped them outperform. Also supporting the Fund's results were investments in emerging market currencies, particularly Brazil and Colombia. Holding back results was the Fund's exposure to bank loans, which constituted about 6% of Fund assets at the end of the period. Bank loans tend to be a defensive area, because of their higher credit 6 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- quality. Nevertheless, bank loan investments underperformed high-yield bonds because of a loss of financial liquidity in the credit markets during the six months. In addition, because the interest rates of bank loans tend to be adjustable, loans become less appealing to investors as interest rates decline and the rates of the loans reset downward. Individual bond holdings that detracted from the Fund's results included those of Huawei-3Com, a China-based technology company, and Telesat Canada, a satellite communications corporation based in China. Both underperformed in the general market downturn. In addition, bonds of two ethanol producers, Aventine Renewables and Verasun Energy, declined as rising corn prices pressured their operating margins, even during a period of rising energy prices. Other investments that held back results included asset-backed securities of Dunkin' Donuts and Domino's Pizza, both of which lagged because of the secondary effects that the credit crisis had on asset-backed securities. Q: What is your investment outlook? A: Even after rallying in the final six weeks of the six-month period ended April 30, 2008, the valuations of domestic corporate high-yield bonds continue to appear attractive and high-yield bonds retain wide yield advantages over Treasuries. The fixed-income markets may be volatile in the weeks ahead, but we believe investors are well compensated for the credit risks of high yield bonds, especially domestic bonds. We also may consider selectively increasing the Fund's exposure to asset-backed securities and subprime-related securities if we see very attractive prices created by the extreme market fluctuations of the previous months. If forecasts for the U.S. economy become less pessimistic, we believe the U.S. dollar may show renewed strength and investments in the euro and other foreign currencies may be less rewarding. The emerging markets have outperformed developed markets by wide margins in recent years, and growth in emerging markets should continue to outpace developed markets. However, the valuations of emerging market bonds at the end of the period were not as attractive as they had been relative to other securities. We anticipate continuing to look for opportunities in emerging 7 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 4/30/08 (continued) - -------------------------------------------------------------------------------- markets, but we intend to be selective as we pick investments on case-by-case analysis. 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. The Fund can invest in a limited number of securities and, as a result, the Fund's performance may be more volatile than the performance of other funds holding more securities. 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. Any information in this shareholder report regarding market or economic trends or the factors influencing the Fund's historical or future performance are statements of the opinion of Fund management as of the date of this report. These statements should not be relied upon for any other purposes. Past performance is no guarantee of future results, and there is no guarantee that market forecasts discussed will be realized. 8 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- PORTFOLIO SUMMARY 4/30/08 - -------------------------------------------------------------------------------- Portfolio Diversification - -------------------------------------------------------------------------------- (As a percentage of total investment portfolio) [THE FOLLOWING DATA WAS REPRESENTED AS A PIE CHART IN THE PRINTED MATERIAL] U.S. Corporate Bonds 79.6% Temporary Cash Investment 7.5% Senior Secured Loans 6.3% Asset-Backed Securities 2.4% Convertible Corporate Bonds 1.0% Collateralized Mortgage Obligations 1.0% Municipal Bonds 0.8% Foreign Government Bonds 0.8% Rights/Warrants 0.4% Convertible Preferred Stocks 0.2% 10 Largest Holdings - -------------------------------------------------------------------------------- (As a percentage of total debt holdings)* 1.

The index includes sovereign issuers rated BBB1 and lower along with corporate issuers rated BB1 and lower. There are no restrictions on issuer country of domicile. However, the bonds must be publicly issued in a developed market (i.e., investment-grade country). Index returns are calculated monthly, assume reinvestment of dividends and, unlike Fund returns, do not reflect any fees, expenses or sales charges. You cannot invest directly in an index. The index defined here pertains to the "Value of $10,000 Investment" charts appearing on pages 11-15. 10 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- PERFORMANCE UPDATE 4/30/08 CLASS A SHARES - -------------------------------------------------------------------------------- Investment Returns - -------------------------------------------------------------------------------- The mountain chart on the right shows the change in value of a $10,000 investment made in Pioneer Global High Yield Fund at public offering price, compared to that of the Merrill Lynch (ML) Global High Yield and Emerging Markets Plus Index. - -------------------------------------------------------------------------------- Average Annual Total Returns (As of April 30, 2008) Net Asset Public Offering Period Value (NAV) Price (POP) Life-of-Class (8/27/01) 11.52% 10.75% 5 Years 10.41 9.40 1 Year -3.02 -7.35 - -------------------------------------------------------------------------------- Expense Ratio (Per prospectus dated March 1, 2008) Gross Net 1.06% 1.06% - -------------------------------------------------------------------------------- [THE FOLLOWING DATA WAS REPRESENTED AS A MOUNTAIN CHART IN THE PRINTED MATERIAL] Pioneer ML Global Global High Yield and High Yield Emerging Markets Fund Plus Index 8/01 $ 9,550 $10,000 $10,163 $10,157 4/03 $12,102 $11,601 $14,238 $13,332 4/05 $16,148 $14,714 $18,021 $16,192 4/07 $20,478 $18,298 4/08 $19,860 $18,615 Call 1-800-225-6292 or visit www.pioneerinvestments.com for the most recent month-end performance results.

The performance does not reflect differences in expenses, including the Rule 12b-1 fees applicable to Class A shares. Since fees for Class A shares are generally higher than those of Class Y shares, the performance shown for Class Y shares prior to their inception on December 28, 2005 would have been higher. Class Y shares are not subject to sales charges and are available for limited groups of eligible investors, including institutional investors. All results are historical and assume the reinvestment of dividends and capital gains. Other share classes are available for which performance and expenses will differ. 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.

Investment return and principal value will fluctuate, and shares, when redeemed, may be worth more or less than their original cost. Performance for periods prior to the inception of Class Z shares reflects the NAV performance of the Fund's Class A shares. The performance does not reflect differences in expenses, including the Rule 12b-1 fees applicable to Class A shares. Since fees for Class A shares are generally higher than those of Class Z shares, the performance shown for Class Z shares prior to their inception July 6, 2007 would have been higher. Class Z shares are not subject to sales charges and are available for limited groups of eligible investors, including institutional investors.

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, 2007 through April 30, 2008. Share Class A B C Y Z - --------------------------------------------------------------------------------------------- Beginning Account Value $1,000.00 $1,000.00 $1,000.00 $1,000.00 $1,000.00 On 11/1/07 Ending Account Value (after $ 972.30 $ 968.30 $ 968.40 $ 976.30 $ 981.90 expenses) On 4/30/08 Expenses Paid During Period* $ 5.39 $ 9.30 $ 8.96 $ 3.54 $ 3.65 * Expenses are equal to the Fund's annualized expense ratio of 1.10%, 1.90%, 1.83%, 0.72%, and 0.74% multiplied by the average account value over the period, multiplied by 182/366 (to reflect the partial year period). 16 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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. Expenses Paid on a $1,000 Investment in Pioneer Global High Yield Fund Based on a hypothetical 5% per year return before expenses, reflecting the period from November 1, 2007 through April 30, 2008.

Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 4/30/08 (unaudited) - -------------------------------------------------------------------------------- 1. Organization and Significant Accounting Policies Pioneer Global High Yield Fund (the Fund) is a series of Pioneer Series Trust VII, a Delaware statutory trust registered under the Investment Company Act of 1940 as a non-diversified, open-end management investment company. The investment objective of the Fund is to maximize total return through a combination of income and capital appreciation. The Fund offers five classes of shares - Class A, Class B, Class C, Class Y and Class Z shares. Class Y shares were first publicly offered on December 28, 2005. Class Z shares were first publicly offered on July 6, 2007. 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 and Class C shareowners, respectively. There is no distribution plan for Class Y and Class Z 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 year. Actual results could differ from those estimates. 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. 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. The Fund's prospectuses contain information regarding the Fund's principal risks. Please refer to those documents when considering the Fund's risks. 57 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 4/30/08 (unaudited) (continued) - -------------------------------------------------------------------------------- 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 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 using fair value methods pursuant to procedures adopted by the Board of Trustees. At April 30, 2008 there were no securities that were valued using fair value methods. Temporary cash investments are valued at cost which approximates market value. 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 58 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. 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, if any, 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. (See Note 8) 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. Tax years prior to 2004 are 59 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 4/30/08 (unaudited) (continued) - -------------------------------------------------------------------------------- closed (not subject to examination by tax authorities) due to the statute of limitations; all other tax years remain open. 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 from or in excess of net investment income or as from net realized gain on investment transactions, or as 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, 2007 was as follows: - -------------------------------------------------------------------------------- 2007 - -------------------------------------------------------------------------------- Distributions paid from: Ordinary income $133,484,600 Long-term capital gain 3,117,875 ------------ Total $136,602,475 ============ - -------------------------------------------------------------------------------- The following shows the components of distributable earnings on a federal income tax basis at October 31, 2007: - -------------------------------------------------------------------------------- 2007 - -------------------------------------------------------------------------------- Undistributed ordinary income $15,803,280 Undistributed long-term gain 14,654,845 Dividend payable (4,489,347) Unrealized depreciation (19,286,359) ----------- Total $ 6,682,419 =========== - -------------------------------------------------------------------------------- The difference between book-basis and tax-basis unrealized depreciation is attributable to the tax deferral of losses on wash sales, adjustments relating to catastrophe bonds, the mark to market of forward currency contracts and the tax basis adjustment on partnerships and credit default swaps. 60 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- E. Fund Shares The Fund records sales and repurchases of its shares as of trade date. Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the Fund and a wholly owned indirect subsidiary of UniCredit S.p.A. (UniCredit), earned $374,185 in underwriting commissions on the sale of Class A shares during the six months ended April 30, 2008. F. Class Allocations 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. 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 5). Class Y and Class Z shares are not subject to a distribution plan. Shareowners of each class participate in 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 5). 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, Class C, Class Y and Class Z shares can bear different transfer agent and distribution expense rates. G. Repurchase Agreements With respect to repurchase agreements entered into by the Fund, the value of the underlying securities (collateral), including accrued interest received from counterparties, is required to be at least equal to or in excess of the value of the repurchase agreement at the time of purchase. The collateral for all repurchase agreements is held in safekeeping in the customer-only account of the Fund's 61 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 4/30/08 (unaudited) (continued) - -------------------------------------------------------------------------------- custodian, or sub custodians. The Fund's investment adviser, Pioneer Investment Management, Inc. (PIM), is responsible for determining that the value of the collateral remains at least equal to the repurchase price. H. Securities Lending The Fund lends securities in its portfolio to certain broker-dealers or other institutional investors. When entering into a loan, the Fund receives collateral 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 which is required to be at least 102%, at all times, of the fair value of the securities loaned. The amount of collateral is required to 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 cash equivalent investments. I. Credit Default Swap Agreements A credit default swap is a contract between a buyer of protection and a seller of protection against a pre-defined credit event. The Fund may buy or sell credit default swap contracts to increase the Fund's income, to add leverage to the Fund or to hedge the risk of default on portfolio securities. As a seller of protection, the Fund would be required to pay the notional (or other agreed-upon) value of the referenced debt obligation to the counterparty in the event of a default by a U.S. or foreign corporate issuer of a debt obligation, which would likely result in a loss to the Fund. In return, the Fund would receive from the counterparty a periodic stream of payments during the term of the contract provided that no event of default occurred. The maximum exposure of loss to the seller would be the notional value of the credit default swaps outstanding. If no default occurs, the Fund would keep the stream of payments and would have no payment obligation. The Fund may also buy credit default swap contracts in order to hedge against the risk of default of debt securities, in which case the Fund would function as the counterparty referenced above. 62 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- When the Fund enters into a credit default swap contract, one party, the protection buyer, makes an upfront or periodic payment to the protection seller in exchange for the right to receive a contingent payment. An upfront payment received by the Fund, as the protection seller, is recorded as a liability in the Fund's records. An upfront payment made by the Fund, as the protection buyer, is recorded as an asset in the Fund's records. Periodic payments received or paid by the Fund are recorded as realized gains or losses. The credit default swap contracts are marked-to-market daily using valuations supplied by independent sources and the change in value, if any, is recorded as unrealized gain or loss. Payments received or made as a result of a credit event or upon termination of the contract are recognized, net of the appropriate amount of the upfront payment, as realized gains or losses. Credit default swap contracts involving the sale of protection may involve greater risks than if the Fund had invested in the referenced debt instrument directly. Credit default swap contracts are subject to general market risk, liquidity risk, counterparty risk and credit risk. If the Fund is a protection buyer and no credit event occurs, it will lose its investment. If the Fund is a protection seller and a credit event occurs, the value of the referenced debt instrument received by the Fund, together with the periodic payments received, may be less than the amount the Fund pays to the protection buyer, resulting in a loss to the Fund. There were no credit default swap contracts outstanding at April 30, 2008. Valuation Credit default swaps are valued by an independent pricing service based upon valuation models incorporating default probabilities, estimated recovery rates, actual reported transactions, and other available market data. 2. Unfunded Loan Commitments As of April 30, 2008, the Fund had unfunded loan commitments of approximately $481,643 (excluding unrealized depreciation on those commitments of $19,318 as of April 30, 2008) which could be 63 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 4/30/08 (unaudited) (continued) - -------------------------------------------------------------------------------- extended at the option of the borrower, pursuant to the following loan agreements: - -------------------------------------------------------------------------------- Unfunded Borrower Commitment - -------------------------------------------------------------------------------- HUB International, Ltd., Delayed Draw Term Loan $ 184,426 Telesat Canada, Delayed Draw Term Loan $ 297,217 - -------------------------------------------------------------------------------- 3. Management Agreement Pioneer Investment Management, Inc. (PIM), a wholly owned indirect subsidiary of UniCredit, 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; 0.65% of the next $500 million; and 0.60% of the excess over $1 billion. Effective January 1, 2007, Pioneer's fee is subject to an additional breakpoint. The Fund pays Pioneer a fee at the annual rate of 0.55% of the Fund's average daily net assets greater than $1.5 billion. For the six months ended April 30, 2008, the net management fee was equivalent to 0.63% of the average daily net assets. 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, 2011 for Class A shares and through March 1, 2009 for Class B and Class C shares. Pioneer has contractually agreed to limit ordinary operating expenses to the extent required to reduce Fund expenses to 0.90% of the average daily net assets attributable to Class Z shares. This expense limitation is in effect through March 1, 2011 for Class Z 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. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $35,460 in management fees, administrative costs and certain other services payable to PIM at April 30, 2008. 64 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 4. Transfer Agent PIMSS, a wholly owned indirect subsidiary of UniCredit, provides substantially all transfer agent and shareowner services to the Fund at negotiated rates. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $213,881 in transfer agent fees receivable from PIMSS at April 30, 2008. 5. Distribution Plan 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 Plan, the Fund pays PFD 0.25% of the average daily net assets attributable to Class A shares as compensation for personal services and/or account maintenance services or distribution services with regard to Class A Shares. Pursuant to the Plan, the Fund pays PFD 1.00% of the average daily net assets attributable to Class B and Class C shares. The fee for Class B and Class C shares 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. For the period from November 1, 2007 through January 31, 2008, PFD was reimbursed under the Plan of Distribution for distribution expenses in an amount of up to 0.25% of the average daily net assets attributable to Class A shares. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $26,801 in distribution fees payable to PFD at April 30, 2008. In addition, redemptions of each class of shares (except Class Y and Class Z shares) may be subject to a contingent deferred sales charge (CDSC). 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. Class B shares 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% based on the lower of cost or market value of shares being redeemed. Proceeds from the CDSCs are paid to PFD. For the six months ended April 30, 2008, CDSCs in the amount of $344,619 were paid to PFD. 65 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 4/30/08 (unaudited) (continued) - -------------------------------------------------------------------------------- 6. Line of Credit Facility The Fund, along with certain other funds in the Pioneer Family of Funds (the Funds), collectively participate in a $200 million committed, unsecured revolving line of credit facility. Borrowings are used solely for temporary or emergency purposes. The Fund may borrow up to the lesser of $200 million or the limits set by its prospectus for borrowings. Interest on borrowings is payable at the Federal Funds Rate plus 1/2% on an annualized basis. The Funds pay an annual commitment fee for this facility. The commitment fee is allocated among such Funds based on their respective borrowing limits. For the six months ended April 30, 2008, the Fund had no borrowings under this agreement. 7. 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, 2008, the Fund's expenses were reduced by $32,974 under such arrangements. 8. Forward Foreign Currency Contracts At April 30, 2008, the Fund had entered into various contracts that obligate the Fund to deliver currencies at specified future dates. At the maturity of a contract, the Fund must make delivery of the foreign currency. Alternatively, prior to the settlement date of a portfolio hedge, the Fund may close out such contracts by entering into an offsetting hedge contract. Open Portfolio hedges at April 30, 2008 were as follows: - ----------------------------------------------------------------------------------------------- Net Net Contracts to In Exchange Settlement Unrealized Currency (deliver)/receive For Date Value Gain - ----------------------------------------------------------------------------------------------- EUR (Euro) (47,900,000) $ (74,831,775) 5/30/08 $ (74,812,615) $19,160 - ----------------------------------------------------------------------------------------------- At April 30, 2008, the Fund had no outstanding settlement hedges. 9. New Pronouncements In September 2006, Statement of Financial Accounting Standards No. 157, Fair Value Measurements (SFAS 157), was issued and is effective for fiscal years beginning after November 15, 2007. 66 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Management is currently evaluating the impact the adoption of SFAS 157 will have on the Fund's financial statement disclosures. In March 2008, Statement of Financial Accounting Standards No. 161, Disclosures about Derivative Instruments and Hedging Activities ("SFAS 161"), was issued and is effective for fiscal years beginning after November 15, 2008. SFAS 161 requires enhanced disclosures about an entity's derivative and hedging activities. Management is currently evaluating the impact the adoption of SFAS 161 will have on the Fund's financial statement disclosures. 67 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- APPROVAL OF INVESTMENT ADVISORY AGREEMENT - -------------------------------------------------------------------------------- Pioneer Investment Management, Inc. (PIM) serves as the Fund's investment adviser pursuant to an investment advisory agreement between PIM and the Fund. The Trustees of the Fund, as required by law, determine annually whether to continue the investment advisory agreement for the Fund. In connection with their most recent consideration of the investment advisory agreement for the Fund, the Trustees received and reviewed a substantial amount of information provided by PIM in response to requests of the independent Trustees and their independent legal counsel. The independent Trustees met on a number of occasions with PIM and also separately with their independent legal counsel to evaluate and discuss the information provided to them by PIM. At a meeting held on November 13, 2007, based on their evaluation of the information provided by PIM, the Trustees, including the independent Trustees voting separately, unanimously approved the continuation of the investment advisory agreement for another year. In considering the continuation of the investment advisory agreement, the Trustees considered various factors that they determined were relevant, including the factors described below. The Trustees did not identify any single factor as the controlling factor in determining to approve the continuation of the agreement. Nature, Extent and Quality of Services The Trustees considered the nature, extent and quality of the services provided by PIM to the Fund, taking into account the investment objective and strategy of the Fund and the information related to the Fund provided to the Trustees at each quarterly meeting. The Trustees reviewed the terms of the investment advisory agreement. The Trustees also reviewed PIM's investment approach for the Fund and its research process. The Trustees considered the resources of PIM and the personnel of PIM who provide investment management services to the Fund. They also considered PIM's compliance and legal resources and personnel. In addition, the Trustees considered the other services that PIM provides to the Fund under the investment advisory agreement and that, as administrator, PIM is responsible for the administration of the Fund's business and other affairs. It was noted that PIM supervises and monitors the performance of the Fund's service providers and provides the Fund with personnel (including officers) as are necessary 68 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- for the Fund's operations. The Trustees considered the fees paid to PIM for the provision of such services. Based on these considerations, the Trustees concluded that the nature, extent and quality of services provided by PIM to the Fund were satisfactory and consistent with the terms of the investment advisory agreement. Performance of the Fund The Trustees considered the performance results of the Fund over various time periods. They reviewed information comparing the Fund's performance with the average performance of its peer group of funds as classified by Morningstar, Inc. (Morningstar), an independent provider of investment company data, and with the performance of the Fund's benchmark index. The Trustees considered that the Fund's annualized total return was in the first quintile of its Morningstar category for the one, three and five year periods ended June 30, 2007. (In all quintile rankings referred to throughout this disclosure, first quintile is most favorable to the Fund's shareowners. Thus, highest relative performance would be first quintile and lowest relative expenses would also be first quintile.) The Trustees concluded that the investment performance of the Fund was satisfactory. Management Fee and Expenses The Trustees considered information on the fees and expenses of the Fund in comparison to the management fees of its peer group of funds as classified by Morningstar and the expense ratios of a peer group of funds selected on the basis of criteria determined by the independent Trustees for this purpose using data provided by Strategic Insight Mutual Fund Research and Consulting, LLC (Strategic Insight), an independent third party. The Trustees considered that the Fund's management fee for the twelve months ended June 30, 2007 was in the fourth quintile relative to the management fees paid by other funds in its peer group Morningstar category for the comparable period. The Trustees also considered that the Fund's expense ratio for the twelve months ended June 30, 2007 was in the fourth quintile relative to its Strategic Insight peer group. The Trustee noted that the Fund's management fee recently was lowered and that the impact of the lower management fee was not fully reflected in the data. They also considered PIM's agreement to add a breakpoint to the management fee schedule as described below. 69 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- APPROVAL OF INVESTMENT ADVISORY AGREEMENT (continued) - -------------------------------------------------------------------------------- The Trustees also reviewed management fees charged by PIM to its separate account clients with a similar investment strategy as the Fund. The Trustees noted that in some instances the fee rates for those separate accounts were lower than the management fees for the Fund and considered that, under the investment advisory agreement with the Fund, PIM performs additional services for the Fund that it does not provide to those other clients, including oversight of the Fund's other service providers, regulatory compliance and other services. The Trustees concluded that the management fee payable by the Fund to PIM was reasonable in relation to the nature and quality of services provided, taking into account the fees charged by other advisers for managing comparable mutual funds with similar strategies. The Trustees also concluded that the Fund's expense ratio was reasonable, taking into account the size of the Fund, the quality of services provided by PIM, the investment performance of the Fund and the contractual expense limitation agreed to by PIM with respect to the Fund. Profitability The Trustees considered information provided by PIM regarding the profitability of PIM with respect to the advisory services provided by PIM to the Fund, including the methodology used by PIM in allocating certain of its costs to the management of the Fund. The Trustees also considered PIM's profit margin in connection with the overall operation of the Fund. They further reviewed the financial results realized by PIM and its affiliates from non-fund businesses. The Trustees considered PIM's profit margins with respect to the Fund in comparison to the limited industry data available and noted that the profitability of any adviser was affected by numerous factors, including its organizational structure and method for allocating expenses. The Trustees recognized that PIM should be entitled to earn a reasonable level of profit for the services provided to the Fund. The Trustees concluded that PIM's profitability with respect to the management of the Fund was not unreasonable. 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. The 70 Pioneer Global High Yield Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- Trustees considered PIM's agreement to add a breakpoint to the management fee schedule so that the management fee would be reduced for Fund assets in excess of $2 billion. The Trustees reviewed the impact that the breakpoint would have on the Fund's management fee versus its Morningstar category peer group. The Trustees concluded that, because of the addition of the breakpoint in the management fee schedule and the reduced fee rate above certain asset levels, any perceived or potential economies of scale would be shared between PIM and the Fund. Other Benefits The Trustees considered the other benefits to PIM from its relationship with the Fund. The Trustees considered that affiliates of PIM serve as the Fund's transfer agent and distributor. The Trustees considered the receipt by PIM and its affiliates of sales loads and payments under Rule 12b-1 plans in respect of the Fund and the other Pioneer funds. The Trustees further considered the intangible benefits to PIM by virtue of its relationship with the Fund and the other Pioneer funds. The Trustees concluded that the receipt of these benefits was reasonable in the context of the overall relationship between PIM and the Fund. Conclusion After consideration of the factors described above as well as other factors, the Trustees, including all of the independent Trustees, concluded that the terms of the investment advisory agreement between PIM and the Fund, including the fees payable thereunder, were fair and reasonable and voted to approve the proposed continuation of the investment advisory agreement for the Fund. 71 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.

The Fund's audit committee of the Board of Trustees has considered whether the provision of non-audit services that were rendered to the Affiliates (as defined) 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.
