Investors have witnessed volatility of a magnitude that many have never before seen. Distance often provides the best vantage point for perspective. Still, we believe that the benefits of basic investment principles that have stood the test of time -- even in the midst of market turmoil -- cannot be underestimated. First, invest for the long term. The founder of Pioneer Investments, Philip L. Carret, began his investment career during the 1920s. One lesson he learned is that while great prosperity affords an advantageous time for selling stocks, extreme economic slumps can create opportunities for purchase. Indeed, many of our portfolio managers, who follow the value-conscious investing approach of our founder, are looking at recent market conditions as an opportunity to buy companies whose shares we believe have been unjustifiably beaten down by indiscriminate selling, but that we have identified as having strong prospects over time. While investors may be facing a sustained market downturn, we continue to believe that patience, along with staying invested in the market, are important considerations for long-term investors. A second principle is to stay diversified across different types of investments. The global scope of the current market weakness poses challenges for this basic investment axiom. But the turbulence makes now a good time to reassess your portfolio and make sure that your investments continue to meet your needs. We believe you should 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. As the investment markets sort through the continuing crisis in the financial industry, we are staying focused on the fundamentals and risk management. With more than 80 years of experience behind us, we have learned how to navigate turbulent markets. At Pioneer Investments, risk management has always been a critical part of our culture -- not just during periods of extraordinary volatility. Our investment process is based on fundamental research, quantitative analysis and active portfolio management. This three-pillared process, which we apply to each of our portfolios, is supported by an integrated team approach and is designed to carefully balance risk and reward. While we 2 Pioneer Global Aggregate Bond Fund | Semiannual Report | 4/30/09 see potential chances for making money in many corners of the market, it takes research and experience to separate solid investment opportunities from speculation. We invite you to learn more about Pioneer and our time-tested approach to investing by consulting with your financial advisor or visiting us online at www.pioneerinvestments.com. Thank you for investing with Pioneer. Respectfully, /s/ Daniel K. Kingsbury Daniel K. Kingsbury President and CEO Pioneer Investment Management USA Inc.

Pioneer Global Aggregate Bond Fund | Semiannual Report | 4/30/09 3 Portfolio Management Discussion | 4/30/09 Reacting to substantial and widening problems among major financial institutions in the late summer and early fall of 2008, the world's fixed-income markets experienced an unusually high degree of volatility over the six months ended April 30, 2009. Better-quality bonds clearly outperformed during the first four months of the period, as the market witnessed a worldwide flight to quality and safety. However, the credit markets appeared to improve in March and April 2009, leading to improved performance by some credit-exposed asset classes. In the following discussion, Charles Melchreit discusses the performance of Pioneer Global Aggregate Bond Fund during the six months ending April 30, 2009. Mr. Melchreit, a member of Pioneer's Fixed Income Department, is responsible for the daily management of the Fund. Q How did the Fund perform during the six months ended April 30, 2009? A Pioneer Aggregate Bond Fund Class A shares generated a total return of 6.00% at net asset value during the six months ended April 30, 2009, while the Barclays Capital (formerly Lehman Brothers) Global Aggregate Bond Index, the Fund's benchmark, returned 6.68%. During the same period, the average return of the 137 funds in Lipper's Global Income Funds category was 5.79%. On April 30, 2009, the 30-day SEC yield of Class A shares was 4.05%. Q What were the principal factors affecting the Fund's performance during the six months ended April 30, 2009? A The period saw a dramatic change in sentiment in worldwide fixed-income markets, leading to substantial volatility. The first four months of the period saw continuing concerns about the extent of the credit crisis, which drove a global flight to quality. Investments in U.S. Treasuries and government agency securities held up better than those exposed to credit risk, while perceived safe havens such as the U.S. dollar and the Japanese yen also did well. That changed in March 2009, as frozen credit markets appeared to be thawing and investors were more willing to take on credit risk. Despite the change in sentiment, the global economy remained sluggish, with the economies of the U.S., Europe, the United Kingdom and Japan all contracting, although early signs of a potential stabilization surfaced in the U.S. and Japan. Their economies had been the first to fall into recession. Q How did you position the Fund in this environment? A During most of the period, we maintained a high-quality portfolio. We also kept the Fund's duration -- or sensitivity to changes in interest rates -- long because we thought interest rates were likely to decline due to the 4 Pioneer Global Aggregate Bond Fund | Semiannual Report | 4/30/09 accommodative policies of the world's major central banks. The Fund had a significant overweighting in the U.S dollar, but was underweighted to the euro and the British pound. We normally have de-emphasized Japan because of the very low yields available in that nation, but the Fund's underweight was not as dramatic as it had been earlier. Toward the end of the period, however, we started opportunistically to invest the Fund's assets in more credit-sensitive securities, including corporate bonds and non-agency mortgages. At the same time, we added to the Fund's currency exposure to selective resource-based economies, such as Australia and Canada. During the six months ended April 30, 2009, the average credit quality of the Fund's holdings declined from AA to AA-, as we reduced the Fund's AAA exposure by nine percentage points, principally through the sale of U.S. government agency mortgage securities and the acquisition of more corporate bonds and non-agency securities. At the end of the period (April 30, 2009), 48.9% of the Fund's assets were in foreign investment-grade bonds, mainly in government securities of developed nations; 25.4% of assets were invested in mortgage-backed bonds; and 24.6% of Fund assets were invested in investment-grade corporates. U.S. high-yield bonds accounted for 4.8% of assets. Q What types of investments had the greatest impact on the Fund's results during the six-month period ended April 30, 2009? A The Fund's currency positioning, especially the underweight in the British pound, added to returns. In addition, the Fund's long-duration stance in the United States helped, as government bonds rallied when interest rates fell. The 10-year U.S. Treasury, for example, dropped by .83 percentage points (83 basis points), leading to price appreciation. The emphasis on government bonds outside the United States also supported the Fund's results, particularly during the first four months of the period, while the added positions in U.S. corporate debt helped results during the latter part of the period. However, the Fund's relatively short-duration stance in Europe did not help, while exposure to bonds of financial companies based both in the United States and in foreign markets also held back Fund returns. Q What is your investment outlook? A We continue to be cautiously optimistic and plan to continue to add slowly to the Fund's credit exposure. We think investors, over the longer term, should be well compensated for the risks. We also intend to add some structured securities, especially non-agency mortgage-backed securities, where we see good value. We remain cautious about Europe, however, as European economies are expected to lag the United States in emerging from recession. We may decrease the Fund's emphasis on foreign governments and add to positions in foreign corporates. Pioneer Global Aggregate Bond Fund | Semiannual Report | 4/30/09 5 We expect to keep the Fund's duration relatively long, though we will modify this stance if we perceive inflation pressures. In looking at currencies, we believe there is some value in commodity related currencies. We may add to the Fund's positions there, while lightening its exposure to the Japanese yen. Please refer to the Schedule of Investments on pages 14-27 for a full listing of Fund securities. 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 and 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. Past performance is no guarantee of future results, and there is no guarantee that market forecasts discussed will be realized.

Pioneer Global Aggregate Bond Fund | Semiannual Report | 4/30/09 11 Comparing Ongoing Fund Expenses As a shareowner in the Fund, you incur two types of costs: (1) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses; and (2) transaction costs, including sales charges (loads) on purchase payments. 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 November 1, 2008 through April 30, 2009. Share Class A C Y Beginning Account $ 1,000.00 $ 1,000.00 $ 1,000.00 Value on 11/1/08 - -------------------------------------------------------------------------------- Ending Account Value $ 1,060.00 $ 1,055.40 $ 1,060.00 (after expenses) on 4/30/09 - -------------------------------------------------------------------------------- Expenses Paid $ 5.11 $ 9.68 $ 5.16 During Period* - -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.00%, 1.90%, and 1.01% for Class A, Class C, and Class Y respectively, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one half year period) 12 Pioneer Global Aggregate Bond Fund | Semiannual Report | 4/30/09 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.

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 designated as 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 identical rights (based on relative net asset values) to assets and liquidation proceeds. Share classes can bear different class-specific fees and expenses such as transfer agent and distribution fees. Differences in class-specific fees and expenses will result in differences in net investment income and, therefore, the payment of different dividends by each class. The Amended and Restated Declaration of Trust of the Fund gives the Board the flexibility to specify either per share voting or dollar-weighted voting when submitting matters for shareholder approval. Under per share voting, each share of a class of the Fund is entitled to one vote. Under dollar-weighted voting, a shareholder's voting power is determined not by the number of shares owned, but by the dollar value of the shares on the record date. Share classes have exclusive voting rights with respect to matters affecting only that class, including with respect to the distribution plan for that class. 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 period. 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 Pioneer Global Aggregate Bond Fund | Semiannual Report | 4/30/09 35 economic conditions and the imposition of adverse governmental laws or currency exchange restrictions. The Fund's prospectuses contain unaudited information regarding the Fund's principal risks. Please refer to those documents when considering the Fund's principal risks. 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, 2009, one security has been valued using fair value methods, which represents 0.3% of net assets. Temporary cash investments are valued at cost which approximates market value. Dividend income is recorded on the ex-dividend date except that certain dividends from foreign securities where the ex-dividend date may have passed are recorded as soon as the Fund becomes aware of the ex-dividend data in the exercise of reasonable diligence. 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. Dividend and interest income, including interest on income bearing cash accounts, are recorded on the accrual basis and are reported 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 non-diversified, 36 Pioneer Global Aggregate Bond Fund | Semiannual Report | 4/30/09 which means that it can invest a higher percentage of its assets in any one issuer than a diversified fund. Being non-diversified may magnify the Fund's losses from adverse events affecting a particular issuer. B. Foreign Currency Translation The books and records of the Fund are maintained in U.S. dollars. Amounts denominated in foreign currencies are translated into U.S. dollars using current exchange rates. Net realized gains and losses on foreign currency transactions, 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 may enter 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. Tax years for the prior three fiscal years are subject to examination by tax authorities. 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, Pioneer Global Aggregate Bond Fund | Semiannual Report | 4/30/09 37 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 taxable year. The tax character of distributions paid during the period ended October 31, 2008 was as follows: 2008 Distributions paid from: Ordinary income $152,846 Return of capital 42,658 - -------------------------------------------------------- Total $195,504 ======================================================== The following shows the components of distributable earnings on a federal income tax basis at October 31, 2008: 2008 Distributable earnings: Dividend payable $ (15,649) Unrealized depreciation (714,957) - -------------------------------------------------------- Total $ (730,606) ======================================================== The difference between book-basis and tax-basis unrealized depreciation is attributable to the tax deferral of losses on wash sales, the tax treatment on open future contracts and the mark to market of forward currency contracts and options. 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 $328 in underwriting commissions on the sale of Class A shares during the six months ended April 30, 2009. 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, 38 Pioneer Global Aggregate Bond Fund | Semiannual Report | 4/30/09 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 and at the same time, except that Class A, Class C and Class Y shares can bear different transfer agent and distribution expense rates. G. Securities Lending The Fund lends securities in its portfolio to certain broker-dealers or other institutional investors. When entering into a securities loan transaction, the Fund typically receives cash collateral from the borrower equal to at least the value of the securities loaned, which is invested in temporary cash investments. Credit Suisse, New York Branch, as the Fund's securities lending agent, manages the Fund's securities lending collateral. The income earned on the investment of collateral is shared with the borrower and the lending agent in payment of any rebate due to the borrower with respect to the securities loan, and in compensation for the lending agent's services to the Fund. The Fund also continues to receive interest or payments in lieu of dividends on the securities loaned. Gain or loss on the value of the loaned securities that may occur during the term of the loan will be for the account of the Fund. The amount of the 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 terminate the loan and recover the securities from the borrower with prior notice. The Fund will be required to return the cash collateral to the borrower and could suffer a loss if the value of the collateral, as invested, has declined. H. Futures Contracts The Fund may enter into futures transactions to hedge against changes in interest rates, securities prices and currency rates or to seek to increase total return. Upon entering into a futures contract, the Fund is required to deposit with a broker an amount of cash or securities equal to the minimum "initial margin" requirements of the associated futures exchange. Subsequent payments for futures contracts (variation margin) are paid or received by the Fund, depending on the daily fluctuation in the value of the contracts, and are recorded by the Fund as unrealized gains or losses. When the contract is closed, the Fund realizes a gain or loss equal to the difference between the opening and closing value of the contract as well as any fluctuation in foreign currency exchange rates where applicable. The use of futures contracts involves, to varying degrees, elements of market and counterparty risks, which may exceed the amounts recognized by the Fund. Changes in Pioneer Global Aggregate Bond Fund | Semiannual Report | 4/30/09 39 value of the contracts may not directly correlate to the changes in value of the underlying securities. These risks may decrease the effectiveness of the Fund's hedging strategies and potentially result in a loss. At April 30, 2009 open futures contracts were as follows: Number of Contracts Settlement Market Unrealized Type Long/(Short) Month Value Loss Euro-BOBL Future 4 6/09 $463,920 $ (3,767) Euro-BUND Future 2 6/09 245,060 (2,281) - ----------------------------------------------------------------------------------- $ (6,048) - ----------------------------------------------------------------------------------- I. Repurchase Agreements With respect to repurchase agreements entered into by the Fund, the value of the underlying securities (collateral), including accrued interest, is required to be at least equal to or in excess of the value of the repurchase agreement. The collateral for all repurchase agreements is held in safekeeping in the customer-only account of the Fund's custodian or subcustodians. 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. 2. Management Agreement PIM, a wholly-owned indirect subsidiary of UniCredit, 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 contractually agreed to limit ordinary operating expenses of the Fund to the extent required to reduce 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, 2012 for Class A shares and through March 1, 2010 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 $7 in management fees, administrative costs and certain other fees payable to PIM at April 30, 2009. 3. Transfer Agent PIMSS, a wholly owned indirect subsidiary of UniCredit, provides substantially all transfer agent and shareowner services to the Fund at negotiated rates. In addition, the Fund reimbursed PIMSS for out-of-pocket expenses related to shareholder communications activities such as proxy and statement mailings, 40 Pioneer Global Aggregate Bond Fund | Semiannual Report | 4/30/09 outgoing phone calls and omnibus relationship contracts. For the six months ended April 30, 2009, such out-of-pocket expenses by class of shares were as follows: Shareholder Communications: Class A $118 Class C 114 Class Y 13 - ------------------------------------------- Total $245 - ------------------------------------------- Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $1,034 in transfer agent fees and shareholder communications expenses payable to PIMSS at April 30, 2009. 4. Distribution Plan The Fund adopted a Distribution Plan pursuant to Rule 12b-1 of the Investment Company Act of 1940 with respect to its Class A and Class C shares. 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 $82 in distribution fees payable to PFD at April 30, 2009. 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 (within 12 months for purchases made on or after April 1, 2009). 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, 2009, 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 six months ended April 30, 2009, the Fund's expenses were not reduced under such arrangements. Pioneer Global Aggregate Bond Fund | Semiannual Report | 4/30/09 41 6. Forward Foreign Currency Contracts At April 30, 2009, 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, 2009 were as follows: Net Net Contracts to In Exchange Settlement Unrealized Currency (deliver)/receive For Date Value Gain (loss) EUR (European Dollar) 266,006 $ 350,000 5/4/09 $ 352,748 $2,748 GBP (British Pound Sterling) (70,000) (102,901) 5/6/09 (103,775) (874) - -------------------------------------------------------------------------------------------------------- $1,874 - -------------------------------------------------------------------------------------------------------- At April 30, 2009, the Fund had no outstanding settlement hedges. 7. New Pronouncement 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. 42 Pioneer Global Aggregate Bond Fund | Semiannual Report | 4/30/09 Trustees, Officers and Service Providers Trustees Officers John F.

Investors have witnessed volatility of a magnitude that many have never before seen. Distance often provides the best vantage point for perspective. Still, we believe that the benefits of basic investment principles that have stood the test of time -- even in the midst of market turmoil -- cannot be underestimated. First, invest for the long term. The founder of Pioneer Investments, Philip L. Carret, began his investment career during the 1920s. One lesson he learned is that while great prosperity affords an advantageous time for selling stocks, extreme economic slumps can create opportunities for purchase. Indeed, many of our portfolio managers, who follow the value-conscious investing approach of our founder, are looking at recent market conditions as an opportunity to buy companies whose shares we believe have been unjustifiably beaten down by indiscriminate selling, but that we have identified as having strong prospects over time. While investors may be facing a sustained market downturn, we continue to believe that patience, along with staying invested in the market, are important considerations for long-term investors. A second principle is to stay diversified across different types of investments. The global scope of the current market weakness poses challenges for this basic investment axiom. But the turbulence makes now a good time to reassess your portfolio and make sure that your investments continue to meet your needs. We believe you should 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. As the investment markets sort through the continuing crisis in the financial industry, we are staying focused on the fundamentals and risk management. With more than 80 years of experience behind us, we have learned how to navigate turbulent markets. At Pioneer Investments, risk management has always been a critical part of our culture -- not just during periods of extraordinary volatility. Our investment process is based on fundamental research, quantitative analysis and active portfolio management. This three-pillared process, which we apply to each of our portfolios, is supported by an integrated team approach and is designed to carefully balance risk and reward. While we see potential chances for making money in many corners of the market, it takes 2 Pioneer Global Diversified Equity Fund | Semiannual Report | 4/30/09 research and experience to separate solid investment opportunities from speculation. We invite you to learn more about Pioneer and our time-tested approach to investing by consulting with your financial advisor or visiting us online at www.pioneerinvestments.com. Thank you for investing with Pioneer. Respectfully, /s/Daniel K. Kingsbury Daniel K. Kingsbury President and CEO Pioneer Investment Management USA Inc. 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. Pioneer Global Diversified Equity Fund | Semiannual Report | 4/30/09 3 Portfolio Management Discussion | 4/30/09 In the following interview, portfolio managers Harald Staudinger and Michael Rachor discuss the factors that influenced the Fund's performance during the six-month period ended April 30, 2009. Q What factors influenced market performance during the six months ended April 30, 2009? A The global equity markets closed the semiannual period with a modest loss, obscuring the high volatility and dramatically shifting investment environment that characterized the six months as a whole. The first four months of the period were notable for the exceptionally poor market performance, as deteriorating economic conditions prompted investors to flee equities in favor of safer alternatives. In mid-March 2009, the investment picture changed dramatically as the aggressive stimulus efforts by the world's governments and central banks helped spark an extraordinary rally in the global equity markets. The rebound, which lasted for the final seven weeks of the period and saw the major indices rise in excess of 30%, helped erase the majority of the losses that had been generated through the fall of 2008 and winter of 2009. When the dust settled at the end of April, the Morgan Stanley Capital International (MSCI) World Index, the Fund's benchmark, had returned -5.09% over the full six-month period. Q How did the Fund perform during the semiannual period? A The Fund's Class A shares had a total return of -2.49% at net asset value over the six months ended April 30, 2009, outperforming the benchmark MSCI World Index over the same period. Q Can you review how you manage the Fund? A Our process of selecting securities to hold in the Fund is based primarily on a quantitative evaluation of individual stocks, with an additional level of analysis based on a review of company fundamentals. We start by applying a quantitative screen to approximately 2,400 stocks in both developed and emerging markets. Our model incorporates factors related to both a company's valuation and stock price momentum. It is designed to identify those companies that are both low-priced and carry the potential to surprise investors with improved performance. In broad terms, we are seeking to benefit from the tendency of most investors to rely on a company's recent business performance in looking ahead to its prospects. 4 Pioneer Global Diversified Equity Fund | Semiannual Report | 4/30/09 Once we have used our model to gather initial investment ideas, the companies are subjected to fundamental analysis by our research team. Fundamental factors we look at include the strength of the company's business model and balance sheet composition, as well as the outlook for its industry sector. In doing our analysis, the goal is to avoid holding companies that are justifiably inexpensive. Ultimately, we seek to build a portfolio of solid stocks for which investors have unreasonably low expectations, and sell them once expectations become inflated. Q What elements of the Fund's positioning helped and hurt performance during the six months ended April 30, 2009? A Of the contributing factors to the Fund's outperformance, stock selection accounted for the greatest share, followed by its currency overlay. However, its option overlay detracted from performance. In terms of stock selection, the Fund generated the largest margin of outperformance in the financial sector. Here, the Fund benefited from both an underweight position and strong stock selection. In the banking industry, the leading performers were National Bank of Canada, JPMorgan Chase, and BOC Hong Kong Holdings. Stock picks also performed well in insurance, led by UNUM Provident, and in real estate, where the top performer was Henderson Land Development, based in Hong Kong. Our stock selection process also worked well in the industrials sector, where the leading performer was Austria-based Andritz Group, which makes customized plant, systems and services for the hydropower, pulp and paper, and steel industries. Also adding value to the Fund within industrials were the German defense company Rheinmettal; Metso, a Finland-based supplier of process industry machinery and systems; and Man Stamm, a manufacturer of climate control systems. Technology was a further source of positive performance for the Fund, thanks to the gains registered by Sun Microsystems and Seagate Technology. Our stock selection process also generated meaningful outperformance for the Fund in the health care, materials, and consumer staples sectors. At a time of positive relative performance for the Fund, the leading detractors were largely stock-specific in nature. For instance, a position in Satyam Computer Services dampened performance within technology. The stock fell to near-zero during the period immediately following the stunning revelation that the company had been padding its financial results for years. Positions in the U.S. companies El Paso and Bank of New York Mellon, along with a holding in the British financial company Man Group, were further detractors of note. On a sector basis, the Fund was helped by being Pioneer Global Diversified Equity Fund | Semiannual Report | 4/30/09 5 overweight in materials, but that was offset by an overweight in health care and underweights in technology and retail. Q Do you have any closing thoughts? A Given our model's philosophy -- that reversion to the mean will occur over time for undervalued stocks -- we believe that any sign of overall macroeconomic stabilization is a positive. Although the markets recovered nicely in the final two months of the period, many stocks remain undervalued. We believe this has created a fertile environment in which to employ our value-driven strategy for the Fund, particularly if an improving economic outlook causes valuations to revert to more normalized levels. Please refer to the Schedule of Investments on pages 12-21 for a full listing of Fund securities. Investing in foreign and/or emerging markets securities involves risks relating to interest rates, currency exchange rates, economic, and political conditions. Small- and mid-sized companies may offer the potential for higher returns, but are also subject to greater short-term price fluctuations than larger, more established companies. 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. Past performance is no guarantee of future results, and there is no guarantee that market forecasts discussed will be realized. 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 opinions should not be relied upon for any other purposes. 6 Pioneer Global Diversified Equity Fund | Semiannual Report | 4/30/09 Portfolio Summary | 4/30/09 Portfolio Diversification - -------------------------------------------------------------------------------- (As a percentage of total investment portfolio) [THE FOLLOWING DATA IS REPRESENTED AS A PIE CHART IN THE PRINTED MATERIAL.] International Common Stocks 58.5% U.S. Common Stocks 40.1% Depositary Receipts for International Stocks 1.0% International Preferred Stocks 0.4% Geographical Distribution - -------------------------------------------------------------------------------- (As a percentage of equity holdings) [THE FOLLOWING DATA IS REPRESENTED AS A BAR CHART IN THE PRINTED MATERIAL.] United States 37.5% Japan 16.5% Germany 6.0% France 5.4% Spain 3.8% United Kingdom 3.8% Netherlands 3.5% Switzerland 2.7% Bermuda 2.7% Finland 2.3% People's Republic of China 2.2% Austria 2.1% Hong Kong 1.9% Italy 1.9% Belgium 1.6% Singapore 1.4% Canada 1.3% Cayman Islands 1.1% Russia 1.0% Other (individually less than 1%) 1.3% 10 Largest Holdings - -------------------------------------------------------------------------------- (As a percentage of equity holdings)* 1.

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. POP returns reflect deduction of maximum 5.75% sales charge. NAV results represent the percent change in net asset value per share. Returns would have been lower had sales charges been reflected. 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. Certain fee waivers are contractual through a specified period. Otherwise, fee waivers can be rescinded at any time. See the prospectus and financial statements for more information. The net expense ratio reflects contractual expense limitations currently in effect through 3/1/12 for Class A shares. There can be no assurance that Pioneer will extend the expense limitations beyond such time. Please see the prospectus and financial statements for more information. The performance table and graph do not reflect the deduction of taxes that a shareowner would pay on Fund distributions or the redemption of Fund shares. The Morgan Stanley Capital International (MSCI) World Index is a free float-adjusted market capitalization index designed to measure developed-market equity performance throughout the world. Index returns assume reinvestment of dividends and, unlike fund returns, do not reflect any fees, expenses or sales charges. You cannot invest directly in an index. Pioneer Global Diversified Equity Fund | Semiannual Report | 4/30/09 9 Comparing Ongoing Fund Expenses As a shareowner in the Fund, you incur two types of expenses: (1) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses (2) transaction costs, including sales charges (loads) on purchase payments. 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 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 Diversified Equity Fund Based on actual returns from November 1, 2008 through April 30, 2009. - --------------------------------------------------- Share Class A - --------------------------------------------------- Beginning Account Value on 11/1/08 $ 1,000.00 - --------------------------------------------------- Ending Account Value on 4/30/09 $ 975.10 - --------------------------------------------------- Expenses Paid During Period* $ 6.37 - --------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.30% for Class A shares, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year in the period). 10 Pioneer Global Diversified Equity Fund | Semiannual Report | 4/30/09 Hypothetical Example for Comparison Purposes The second 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 Diversified Equity Fund Based on a hypothetical 5% per year return before expenses, reflecting the period from November 1, 2008 through April 30, 2009. - --------------------------------------------------- Share Class A - --------------------------------------------------- Beginning Account Value on 11/1/08 $ 1,000.00 - --------------------------------------------------- Ending Account Value on 4/30/09 $ 1,018.35 - --------------------------------------------------- Expenses Paid During Period* $ 6.51 - --------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.30% for Class A shares, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period).

Pioneer Global Diversified Equity Fund | Semiannual Report | 4/30/09 25 Notes to Financial Statements | 4/30/09 (unaudited) 1. Organization and Significant Accounting Policies Pioneer Global Diversified Equity 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 diversified, open-end management investment company. The Fund was organized on June 3, 2008. Prior to June 3, 2008, the Fund had no operations other than those relating to organizational matters and the initial capitalization of the Fund by Pioneer Funds Distributor, Inc. (PFD). To date, no shares have been offered to the public. The Fund shares outstanding at April 30, 2009, are owned by PFD. The Fund's investment objective is to seek long-term capital growth. 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 gains and losses on investments during the reporting period. Actual results could differ from those estimates. The Fund's investments in emerging markets or countries with limited or developing markets may subject the Fund to a greater degree of risk than investments in a developed market. Risks associated with these developing markets include political, social or economic factors and may affect the price of the Fund's investments and income generated by these investments, as well as the Fund's ability to repatriate such amounts. 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 prospectus contains unaudited information regarding the Fund's principal risks. Please refer to the document when considering the Fund's principal risks. 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: 26 Pioneer Global Diversified Equity Fund | Semiannual Report | 4/30/09 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. Securities that have not traded on the date of valuation, or securities for which sale prices are not generally reported, are valued at the mean between the last bid and asked prices. Securities for which market prices and/or quotations are not readily available are valued using fair value methods pursuant to procedures adopted by the Board of Trustees. The Fund invests primarily in securities of non-U.S. issuers. The principal exchanges and markets for such securities have closing times prior to the close of the NYSE. However, the value of these securities may be influenced by changes in global markets occurring after the closing times of the local exchanges and markets up to the time the Fund determines its net asset value. Consequently, the Board of Trustees of the Fund has determined that the use of daily fair valuations as provided by a pricing service is appropriate for the Fund. The Fund may also take into consideration other significant events in determining the fair value of these securities. Thus, the Fund's securities valuations may differ from prices reported by the various local exchanges and markets. At April 30, 2009, there were no securities that were valued using fair value methods (other than securities valued using prices supplied by independent pricing services). Temporary cash investments are valued at cost which approximates market value. Dividend income is recorded on the ex-dividend date except that certain dividends from foreign securities where the ex-dividend date may have passed are recorded as soon as the Fund becomes aware of the ex-dividend data in the exercise of reasonable diligence. Interest income, including interest on income bearing cash accounts, is recorded on the accrual basis. Dividend and interest income are reported 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. 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 Pioneer Global Diversified Equity Fund | Semiannual Report | 4/30/09 27 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 prices of those securities but are included with the net realized and unrealized gain or loss on investments. C. Forward Foreign Currency Contracts The Fund may enter 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 5). 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 for the prior three fiscal years are subject to examination by tax authorities. In addition to the requirements of the Internal Revenue Code, the Fund may also be required to pay local taxes on the repatriation of certain foreign currencies and/or net realized capital gains in certain countries. During the year ended October 31, 2008, the Fund paid no such taxes. In determining daily net asset value, the Fund estimates the reserve for such taxes, if any, associated with investments in certain countries. The estimated reserve for capital gains taxes, if any, is based on the net unrealized appreciation of certain portfolio securities, the holding periods of such securities and the related tax rates, tax loss carryforward (if applicable) and other such factors. As of October 31, 2008, the Fund did not have a reserve related to capital gains. 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, 28 Pioneer Global Diversified Equity Fund | Semiannual Report | 4/30/09 or as from paid-in capital, depending on the type of book/tax differences that may exist. As of October 31, 2008, the Fund has a net capital loss carryforward of $160,413, which will expire in 2016 if not utilized. The tax character of current year distributions paid will be determined at the end of the current taxable year. There were no distributions paid during the period ended October 31, 2008. The following shows the components of distributable earnings on a federal income tax basis at October 31, 2008: - ---------------------------------------------------- 2008 - ---------------------------------------------------- Distributable earnings: Undistributed ordinary income $ 6,889 Capital loss carryforward (160,413) Unrealized depreciation (998,753) - ---------------------------------------------------- Total $ (1,152,277) =================================================== The difference between book-basis and tax-basis unrealized appreciation is attributable to the tax deferral of losses on wash sales and the tax treatment on open future contracts, the mark to market on forward foreign currency contracts and options. E. Fund Shares The Fund records sales and repurchases of its shares as of trade date. PFD, the principal underwriter for the Fund and a wholly owned indirect subsidiary of UniCredit S.p.A (UniCredit), earned no underwriting commissions on the sale of Class A shares during the six months ended April 30, 2009. F. Class Allocations Income, common expenses and realized and unrealized gains and losses are calculated at the Fund level and allocated daily to each class 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 shares of the Fund (see Note 4). Distributions to shareowners are recorded as of the ex-dividend date. G. Futures Contracts The Fund may enter into futures transactions to hedge against changes in interest rates, securities prices and currency rates or to seek to increase total return. Upon entering into a futures contract, the Fund is required to deposit with a broker an amount of cash or securities equal to the minimum "initial margin" requirements of the associated futures exchange. Subsequent payments for futures contracts ("variation margin") are paid or Pioneer Global Diversified Equity Fund | Semiannual Report | 4/30/09 29 received by the Fund, depending on the daily fluctuation in the value of the contracts, and are recorded by the Fund as unrealized gains or losses. When the contract is closed, the Fund realizes a gain or loss equal to the difference between the opening and closing value of the contract. The use of futures contracts involves, to varying degrees, elements of market and counterparty risks, which may exceed the amounts recognized by the Fund. Changes in value of the contracts may not directly correlate to the changes in value of the underlying securities. These risks may decrease the effectiveness of the Fund's hedging strategies and potentially result in a loss. At April 30, 2009, open futures contracts were as follows. - -------------------------------------------------------------------------- Number of Contracts Settlement Market Unrealized Type Long/(Short) Month Value Gain - -------------------------------------------------------------------------- S&P 500 1 06/09 $43,500 $7,635 H. Option Writing When the Fund writes an option, an amount equal to the premium received by the Fund is recorded as a liability and is subsequently adjusted to the current fair value of the option written. Premiums received from writing options that expire unexercised are treated by the Fund on the expiration date as realized gains from investments. The difference between the premium and the amount paid on effecting a closing purchase transaction, including brokerage commissions, is also treated as a realized gain, or, if the premium is less than the amount paid for the closing purchase transaction, as a realized loss. If a call option is exercised, the premium is added to the proceeds from the sale of the underlying security in determining whether the Fund has realized a gain or loss. The Fund as writer of an option bears the market risk of an unfavorable change in the price of the security underlying the written option. Transactions in written options for the six months ended April 30, 2009, are summarized as follows: - --------------------------------------------------------------------------- Number of Premiums Contracts Received - --------------------------------------------------------------------------- Options outstanding at beginning of period 7 $ 18,514 Options opened 22 45,086 Options exercised -- -- Options closed (23) (55,658) Options expired -- -- - --------------------------------------------------------------------------- Options outstanding at end of period 6 $ 7,942 =========================================================================== 30 Pioneer Global Diversified Equity Fund | Semiannual Report | 4/30/09 2. Management Agreement Pioneer Investment Management, Inc., (PIM) a wholly owned indirect subsidiary of UniCredit, manages the Fund's portfolio. Management fees are calculated daily at the annual rate of 0.75% of the Fund's average daily net assets up to $500 million, 0.70% of the next $500 million and 0.65% on assets over $1 billion. For the six months ended April 30, 2009, the net management fee was equivalent to 0.75% of the Fund's average net assets. Through March 1, 2012, PIM has agreed not to impose all or a portion of its management fee and to assume other operating expenses of the Fund to the extent necessary to limit Class A expenses to 1.30% of the average daily net assets attributable to Class A shares. In addition, under the management and administration agreements, certain other services and costs, including accounting, regulatory reporting and insurance premiums, are paid by the Fund. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $2 in management fees, administrative costs and certain other fees payable to PIM at April 30, 2009. 3. Transfer Agent Pioneer Investment Management Shareholder Services, Inc. (PIMSS), a wholly owned indirect subsidiary of UniCredit, provides substantially all transfer agent and shareowner services to the Fund at negotiated rates. 4. Distribution Plan The Fund has adopted a Distribution Plan pursuant to Rule 12b-1 of the Investment Company Act of 1940 with respect to its Class A shares. 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. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $12 in distribution fees payable to PFD at April 30, 2009. In addition, redemptions of 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 (within 12 months for purchases made on or after April 1, 2009). Proceeds from the CDSCs are paid to PFD. For the six months ended April 30, 2009, no CDSCs were paid to PFD. 5. Forward Foreign Currency Contracts At April 30, 2009, the Fund 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 Pioneer Global Diversified Equity Fund | Semiannual Report | 4/30/09 31 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, 2009, were as follows: - ----------------------------------------------------------------------------------------------------------------------- Net Contracts to In Net (Deliver)/ Exchange Settlement Unrealized Currency Receive For USD Value Date Value Gain (Loss) - ----------------------------------------------------------------------------------------------------------------------- EUR (Euro) 37,495 $ 50,660 $ 50,660 5/15/09 $ 49,719 $ (941) EUR (Euro) (117,963) $(157,628) $(157,628) 5/15/09 $(156,436) $1,192 GBP (British Pound Sterling) 50,000 53,945 $ 72,627 5/15/09 $ 74,093 $1,466 JPY (Japanese Yen) (5,000,000) (37,495) $ (50,660) 5/15/09 $ (50,685) $ (25) - -------------------------------------------------------------------------------------------------------------------- $1,692 ==================================================================================================================== At April 30, 2009, the Fund had no outstanding settlement hedges. 6. New Pronouncement 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.

Investors have witnessed volatility of a magnitude that many have never before seen. Distance often provides the best vantage point for perspective. Still, we believe that the benefits of basic investment principles that have stood the test of time -- even in the midst of market turmoil -- cannot be underestimated. First, invest for the long term. The founder of Pioneer Investments, Philip L. Carret, began his investment career during the 1920s. One lesson he learned is that while great prosperity affords an advantageous time for selling stocks, extreme economic slumps can create opportunities for purchase. Indeed, many of our portfolio managers, who follow the value-conscious investing approach of our founder, are looking at recent market conditions as an opportunity to buy companies whose shares we believe have been unjustifiably beaten down by indiscriminate selling, but that we have identified as having strong prospects over time. While investors may be facing a sustained market downturn, we continue to believe that patience, along with staying invested in the market, are important considerations for long-term investors. A second principle is to stay diversified across different types of investments. The global scope of the current market weakness poses challenges for this basic investment axiom. But the turbulence makes now a good time to reassess your portfolio and make sure that your investments continue to meet your needs. We believe you should 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. As the investment markets sort through the continuing crisis in the financial industry, we are staying focused on the fundamentals and risk management. With more than 80 years of experience behind us, we have learned how to navigate turbulent markets. At Pioneer Investments, risk management has always been a critical part of our culture -- not just during periods of extraordinary volatility. Our investment process is based on fundamental research, quantitative analysis and active portfolio management. This three-pillared process, which we apply to each of our portfolios, is supported by an integrated team approach and is designed to carefully balance risk and reward. While we 2 Pioneer Global High Yield Fund | Semiannual Report | 4/30/09 see potential chances for making money in many corners of the market, it takes research and experience to separate solid investment opportunities from speculation. We invite you to learn more about Pioneer and our time-tested approach to investing by consulting with your financial advisor or visiting us online at www.pioneerinvestments.com. Thank you for investing with Pioneer. Respectfully, /s/ Daniel K. Kingsbury Daniel K. Kingsbury President and CEO Pioneer Investment Management USA Inc.

Pioneer Global High Yield Fund | Semiannual Report | 4/30/09 3 Portfolio Management Discussion | 4/30/09 High-yield bond investments continued to struggle in the closing months of 2008 before recovering in the first few months of 2009. In the following discussion, Andrew Feltus, CFA, discusses the performance of Pioneer Global High Yield Fund during the six months ended April 30, 2009. Mr. Feltus, a member of Pioneer's Fixed Income Department, is responsible for the daily management of the Fund. Q How did the Fund perform during the six months ended April 30, 2009? A Pioneer Global High Yield Fund Class A shares generated a total return of 0.49% at net asset value during the six months ended April 30, 2009. Over the same period, the Fund's benchmark, Merrill Lynch High Yield and Emerging Markets Plus Index, returned 17.13%, and the average return of the 474 funds in Lipper's High Current Yield category was 9.18%. On April 30, 2009, the 30-day SEC yield of Class A shares was 18.24%. Q What were the principal factors affecting the Fund's performance during the six months ended April 30, 2009? A The November-December 2008 span was one of the worst periods on record for high-yield investments, but the price declines during those two months set up the conditions for a rally during the first few months of 2009. Investors took encouragement from the actions of the U.S. Federal Reserve Board (the Fed) and the U.S. Treasury Department, and of other central banks overseas to restore liquidity to capital markets and to help improve the capital positions of the financial industry. At the same time, high-yield bond prices appeared to have declined to extremely low prices, which reflected, in our view, an unrealistically negative view of the ability of the economy to recover from recession. During the six-month period ended April 30, 2009, the Fund underperformed its high-yield benchmark and Lipper category average, despite having a lower default record than the overall market. The principal factors leading to the Fund's lagging results were its overweight position in B-rated bonds, which underperformed. The Fund's lack of an emphasis on BB-rated securities, which outperformed the market, did not help. At the same time, the Fund's equal-weighted positions in securities rated CCC and lower held back results, as those securities trailed the overall market. Moreover, the Fund did not have significant exposure to the major auto companies, which were among the better-performing areas of the market in early 2009, as investors tried to find securities selling at deeply discounted prices. In addition, the Fund's investments in commercial mortgage-backed securities 4 Pioneer Global High Yield Fund | Semiannual Report | 4/30/09 struggled during the period, as concerns about non-government agency mortgages widened. At the end of the period on April 30, 2009, the average quality of Fund holdings was B-, with 46.8% of assets invested in B-rated securities, 20.9% in BB-rated debt and 14.3% in bonds rated CCC and lower. U.S. corporate high-yield bonds represented the largest group in the Fund's portfolio, at 58.2% of assets, with another 29.1% invested in emerging-market debt and 7.6% in international high-yield corporates. In general, we did not think foreign high-yield investments were priced sufficiently to compensate for all the risks. During the six-month period, we increased the Fund's exposure to the euro and euro-linked currencies in anticipation that the U.S. dollar was more likely to depreciate. Q What types of investments most influenced Fund results over the six months ended April 30, 2009? A Despite the challenging market, several high-yield securities in the Fund's portfolio performed relatively well. They included bonds of Greentown China, a property developer in China; securities issued by Mirant Jamaica, an electric utility that announced it was buying back its debt; and bonds of TNK/BP, an oil and natural gas production company in Russia. The Fund's overweight positions in chemical industry bonds held back results during a period in which the materials sector in general fared poorly. Two notable underperforming chemical industry investments were the bonds of Nell and Georgia Gulf. Similarly, the bonds of Aleris, an aluminum manufacturer and metals distributor, hurt the Fund's results when the company defaulted. Among the Fund's foreign holdings, the securities of Indepencia, a Brazilian beef producer, produced disappointing results. Q What is your investment outlook? A We think 2009 should show improved conditions for high-yield investments, particularly in the United States, especially if the market moves ahead of economic trends, which has been the historical tendency. In general, we think the U.S. high-yield market has improved, as the risks of financing appear to have decreased, while the potential to deliver strong results remains. As a result, we continue to overweight the Fund in the domestic market, while we have limited its exposure to foreign high-yield bonds, including emerging market debt, because we do not think their yields offer enough of a premium over U.S. securities to justify the risks. We think domestic high-yield corporate bond prices have fallen to reflect a depression-style scenario that is difficult to justify. We believe any mispricing of high-yield securities could present a potential investment opportunity, Pioneer Global High Yield Fund | Semiannual Report | 4/30/09 5 especially as investors search for relative value. We believe the Fund is well positioned to participate in a rebound. Please refer to the Schedule of Investments on pages 16-42 for a full listing of Fund securities. 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. Past performance is no guarantee of future results, and there is no guarantee that market forecasts discussed will be realized.

Performance for periods prior to the inception of Class Z shares on July 6, 2007 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 for Class Z shares prior to their inception July 6, 2007 would have been higher than the performance shown. Class Z 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. Certain fee waivers are contractual through a specified period. Otherwise, fee waivers can be rescinded at any time. See the prospectus and financial statements for more information. The net expense ratio reflects contractual expense limitations currently in effect through 3/1/11 for Class Z shares. There can be no assurance that Pioneer will extend the expense limitations beyond such time. Please see the prospectus and financial statements for more information. The performance table and graph do not reflect the deduction of fees and taxes that a shareowner would pay on Fund distributions or the redemption of Fund shares. Pioneer Global High Yield Fund | Semiannual Report | 4/30/09 13 Comparing Ongoing Fund Expenses As a shareowner in the Fund, you incur two types of costs: (1) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses; and (2) transaction costs, including sales charges (loads) on purchase payments. 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, 2008 through April 30, 2009. - ---------------------------------------------------------------------------------------------------- Share Class A B C Y Z - ---------------------------------------------------------------------------------------------------- Beginning Account $1,000.00 $1,000.00 $1,000.00 $1,000.00 $1,000.00 Value on 5/1/08 - ---------------------------------------------------------------------------------------------------- Ending Account Value $1,004.90 $1,000.20 $1,001.50 $1,006.80 $1,006.80 (after expenses) on 10/31/08 - ---------------------------------------------------------------------------------------------------- Expenses Paid $5.47 $9.92 $9.93 $4.08 $4.48 During Period* - ---------------------------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.10%, 2.00%, 2.00%, 0.82%, and 0.90% for Class A, Class B, Class C, Class Y and Class Z shares, respectively, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one half year period). 14 Pioneer Global High Yield Fund | Semiannual Report | 4/30/09 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.

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 designated as Class A, Class B, Class C, Class Y and Class Z shares. Class Y shares were first publicly offered on December 28, 2005. Each class of shares represents an interest in the same portfolio of investments of the Fund and has identical rights (based on relative net asset values) to voting, redemptions, dividends and liquidation proceeds. The Amended and Restated Declaration of Trust of the Fund gives the Board the flexibility to specify either per share voting or dollar-weighted voting when submitting matters for shareholder approval. Under per share voting, each share of a class of the Fund is entitled to one vote. Under dollar-weighted voting, a shareholder's voting power is determined not by the number of shares owned, but by the dollar value of the shares on the record date. Each class of shares can bear different transfer agent and distribution fees. Class A, Class B, Class C and Class R shareowners have exclusive voting rights with respect to the distribution plan for Class A, Class B, Class C and Class R shares. There is no distribution plan for Class Y shares and Class Z shares. Class B shares convert to Class A shares approximately 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 unaudited 52 Pioneer Global High Yield Fund | Semiannual Report | 4/30/09 information regarding the Fund's principal risks. Please refer to those documents when considering the Fund's principal risks. The Fund invests in below investment grade (high yield) debt securities and preferred stocks. Some of these high yield securities may be convertible into equity securities of the issuer. Debt securities rated below investment grade are commonly referred to as "junk bonds" and are considered speculative. These securities involve greater risk of loss, are subject to greater price volatility, and are less liquid, especially during periods of economic uncertainty or change, than higher rated debt securities. The Fund is not diversified, which means that it can invest a higher percentage of its assets in any one issuer than a diversified fund. Being non-diversified may magnify the Fund's losses from adverse events affecting a particular issuer. The 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, 2009 there were no securities that were valued using fair value methods. Temporary cash investments are valued at cost which approximates market value. 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. 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. Pioneer Global High Yield Fund | Semiannual Report | 4/30/09 53 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 for the prior three fiscal years remain subject to examination by tax authorities. 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. 54 Pioneer Global High Yield Fund | Semiannual Report | 4/30/09 The tax character of distributions paid during the year ended October 31, 2008 was as follows: --------------------------------------------------------------------------- 2008 --------------------------------------------------------------------------- Distributions paid from: Ordinary income $184,322,998 Long-term capital gain 14,654,845 --------------------------------------------------------------------------- Total $198,977,843 ============================================================================ The following shows the components of distributable earnings on a federal income tax basis at October 31, 2008: --------------------------------------------------------------------------- 2008 --------------------------------------------------------------------------- Distributable earnings: Undistributed ordinary income $ 26,612,445 Capital loss carryforward (58,199,667) Current year dividend payable (5,171,586) Unrealized depreciation (765,042,301) --------------------------------------------------------------------------- Total $(801,801,109) ============================================================================ 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 interest on defaulted bonds. 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 $92,237 in underwriting commissions on the sale of Class A shares during the six months ended April 30, 2009. 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). Pioneer Global High Yield Fund | Semiannual Report | 4/30/09 55 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 and at the same time, 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, is required to be at least equal to or in excess of the value of the repurchase agreement. The collateral for all repurchase agreements is held in safekeeping in the customer-only account of the Fund's custodian or subcustodians. 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 securities loan transaction, the Fund typically receives cash collateral from the borrower equal to at least the value of the securities loaned, which is invested in temporary cash investments. Credit Suisse, New York Branch, as the Fund's security lending agent, manages the Fund's securities lending collateral. The income earned on the investment of collateral is shared with the borrower and the lending agent in payment of any rebate due to the borrower with respect to the securities loan, and in compensation for the lending agent's services to the Fund. The Fund also continues to receive interest or payments in lieu of dividends on the securities loaned. Gain or loss on the value of the loaned securities that may occur during the term of the loan will be for the account of the Fund. The amount of the 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 terminate the loan and recover the securities from the borrower with prior notice. The Fund will be required to return the cash collateral to the borrower and could suffer a loss if the value of the collateral, as invested, has declined. 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 56 Pioneer Global High Yield Fund | Semiannual Report | 4/30/09 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. 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. The Fund had no credit default swap contracts in the portfolio or otherwise outstanding at April 30, 2009. 2. Unfunded Loan Commitments As of April 30, 2009, the Fund had no unfunded loan commitments which could be extended at the option of the borrower. Pioneer Global High Yield Fund | Semiannual Report | 4/30/09 57 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 0.60% of the next $500 million, 0.55% or the next $500 million and 0.45% of the excess over $2 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, 2009, 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, 2012 for Class A shares and through March 1, 2010 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, 2012 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 $21,075 in management fees, administrative costs and certain other fees payable to PIM at April 30, 2009. 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. In addition, the Fund paid out-of-pocket expenses incurred by PIMSS related to shareholder activities such as proxy and statement mailings, outgoing phone calls and omnibus relation contracts. For the six months ended April 30, 2009, out-of-pocket expenses were as follows: - -------------------------------------------------------------------------------- Shareholder Communications: - -------------------------------------------------------------------------------- Class A $267,629 Class B 21,254 Class C 92,046 Class Y 3,968 Class Z 261 - -------------------------------------------------------------------------------- Total $385,158 ================================================================================ 58 Pioneer Global High Yield Fund | Semiannual Report | 4/30/09 Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $332,969 in transfer agent fees and shareholder communications expense payable to PIMSS at April 30, 2009. 5. Distribution Plan The Fund adopted a Distribution Plan pursuant to Rule 12b-1 of the Investment Company Act of 1940 with respect to its Class A, Class B and Class C. 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 $14,762 in distribution fees payable to PFD at April 30, 2009. 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, 2009, CDSCs in the amount of $160,986 were paid to PFD. 6. Line of Credit Facility The Fund, along with certain other funds in the Pioneer Family of Funds (the Funds), collectively participate in a $165 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 $165 million or the limits set for borrowing by the Fund's prospectus and the 1940 Act. Interest on collective borrowings is payable as follows: if the London Interbank Offered Rate (LIBOR) on the related borrowing date is greater than or equal to the Federal Funds Rate on such date, the loan bears interest at the LIBOR rate plus 1.25% on an annualized basis, or if the LIBOR rate on the related borrowing date is less then the Federal Funds Rate on such date, the loan bears interest at the Federal Funds Rate plus 1.25% on an annualized basis. The Funds pay an Pioneer Global High Yield Fund | Semiannual Report | 4/30/09 59 annual commitment fee for this facility. The commitment fee is allocated among participating Funds based on an allocation schedule set forth in the credit agreement. For the six months ended April 30, 2009, 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, 2009, the Fund's expenses were reduced by $3,382 under such arrangements. 8. Forward Foreign Currency Contracts At April 30, 2009, 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, 2009 were as follows: - -------------------------------------------------------------------------------------------------- Net Net Contracts to In Exchange Settlement Unrealized Currency (deliver)/receive For Date Value Gain (Loss) - -------------------------------------------------------------------------------------------------- EUR (Euro) 7,600,000 $ 10,051,235 5/04/09 $ 10,078,276 $ 27,041 EUR (Euro) (22,000,000) $(28,941,880) 5/04/09 $(29,176,202) $(234,322) EUR (Euro) (14,400,000) $(19,084,896) 6/05/09 $(19,084,320) $ 576 - -------------------------------------------------------------------------------------------------- $(206,705) ================================================================================================== At April 30, 2009, 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 settlement hedge, the Fund may close out such contracts by entering into an offsetting hedge contract. At April 30, 2009, the Fund's gross forward currency settlement contracts receivable and payable were $19,096,573 and $19,087,200, respectively, resulting in a net receivable of $9,373. 9. New Pronouncement 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. 60 Pioneer Global High Yield Fund | Semiannual Report | 4/30/09 Trustees, Officers and Service Providers Trustees 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.
