But with the memory of a deep recession still lingering, businesses and consumers remained cautious about both investing and spending. While business fundamentals showed signs of improvement, there was still a reluctance to hire, and high unemployment remains a problem. Wary investors, concerned about risk, gravitated towards cash and bonds. We remain generally optimistic about the prospects for economic recovery, although it may occur more slowly than many would like. At Pioneer, we have long advocated the benefits of staying diversified and investing for the long term. This strategy has generally performed well for many investors. Bond markets certainly rewarded investors in the first nine months of 2010. While the equity markets barely budged, equities at the end of September 2010 were inexpensive relative to bonds, compared with historic levels, and represented potentially good value for long-term investors. Pioneer has not changed the basic approach to investing that we have used for more than 80 years. We remain focused on company fundamentals and risk management. Our investment process is based on careful research into individual companies, 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. Our experienced professionals devote themselves to the careful research needed to identify investment opportunities in markets around the world. Our advice, as always, is to work closely with a trusted financial advisor to discuss your goals and work together to develop an investment strategy that meets your individual needs. There is no single best strategy that works for every investor. 2 Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/10 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. We greatly appreciate your trust in us and we thank you for investing with Pioneer. Sincerely, /s/ Daniel K. Kingsbury Daniel K. Kingsbury President and CEO Pioneer Investment Management USA, Inc.

Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/10 3 Portfolio Management Discussion | 10/31/10 Global fixed-income markets, despite shifting trends precipitated by a variety of influences, delivered positive results for the 12 months ended October 31, 2010. Over the full 12-month period, corporate bonds and other credit-sensitive securities provided the best relative returns as the world economy continued to recover from recession. In the following interview, Charles Melchreit discusses the performance of Pioneer Global Aggregate Bond Fund during the 12-month period ended October 31, 2010. Mr. Melchreit, vice president, is responsible for the day-to-day management of the Fund along with Tanguy Le Saout, Head of Government Bond and Value-at-Risk (VAR) portfolios for Pioneer in Europe. Q How did the Fund perform during the 12 months ended October 31, 2010? A Pioneer Global Aggregate Bond Fund Class A shares returned 7.21% at net asset value over the 12 months ended October 31, 2010, while the Fund's benchmark, the Barclays Capital Global Aggregate Bond Index (the Barclays Index), returned 6.89%. Over the same period, the average return of the 159 mutual funds in Lipper's Global Income Funds category was 9.62%. On October 31, 2010, the 30-day SEC yield on the Fund's Class A shares was 2.15%. Q What was the investment environment like during the 12 months ended October 31, 2010? A It was a choppy period in the world's fixed-income markets. Credit-sensitive securities, led by corporate bonds, generally outperformed higher-quality securities during a period in which global economic growth appeared to strengthen. At the same time, government sovereign debt markets experienced a great deal of volatility, especially in Europe, where problems caused by high budget deficits were most evident in countries such as Greece, Ireland and Portugal. Moreover, rising concerns about housing markets in countries such as Italy and Spain added to worries about European markets. The economies of northern European countries such as Germany, Switzerland and the Scandinavian countries, however, appeared healthier. Despite periodic concerns that the global economic recovery might be weakening, corporate bonds generally delivered solid, positive returns as corporations continued to reduce debts, strengthen their balance sheets and improve their profit margins. Nevertheless, corporate bonds did struggle at times, most notably in the spring and early summer of 2010, as it became clear that the strong economic rebound of late 2009 and early 2010 was starting to weaken, particularly in the United States. Business executives 4 Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/10 became somewhat more cautious about their capital spending, while many consumers focused on paying down debts rather than increasing spending. Meanwhile, some of the effects of the Federal government's stimulus spending began tapering off. After Federal Reserve Board (the Fed) Chairman Ben Bernanke outlined new plans to inject more financial liquidity into the economy, however, market trends reversed in late summer 2010 and investors again became attracted to corporate securities, including high-yield bonds in addition to stocks. Commodity-producing economies such as Canada, Australia and Norway generally experienced less volatility as commodity prices rose in response to rising demand, especially from emerging market nations that appeared to be leading the global economic recovery. Interest rates, overall, tended to continue to decline, generally supporting bond prices. Currency markets experienced some volatility, with the euro and euro-linked currencies most affected by the debt problems in Europe. Commodity-linked currencies generally gained. The U.S. dollar produced mixed results, while the Japanese yen was seen as a relatively safe currency haven for most of the 12-month period. Q What were the principal factors that influenced the Fund's performance over the 12 months ended October 31, 2010? A Duration management had a positive influence on the Fund's performance results. We maintained a long duration for the Fund during the 12-month period (duration is a measure of the price sensitivity of a bond portfolio to changes in interest rates); this helped performance, especially on investments in the United States, Germany and the Netherlands, where interest rates declined and bond prices rose. The Fund had shorter duration positions in other developed markets, such as the United Kingdom and Japan. While interest rates declined in those markets, the effects were less significant. In commodity-producing economies, where some central banks moved to reduce inflationary pressures by raising short-term interest rates, we tended to keep the duration of the Fund's investments shorter than the benchmark Barclays Index. That positioning helped the Fund's performance results. At the end of the Fund's fiscal year on October 31, 2010, the average effective duration of the Fund's assets was 4.65 years. The Fund's emphasis on corporate securities and underweight positions in sovereign government debt provided further support to performance over the 12-month period. We placed the greatest focus on investment-grade corporate bonds, which outperformed government credits, including U.S. Treasury and government agency securities. At the end of the Fund's fiscal year on October 31, 2010, the Fund had 22% of its assets invested in U.S. investment-grade corporate bonds. The Fund Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/10 5 did have another 18.5% of assets invested in mortgage-backed securities, but in that area we placed an emphasis on non-agency mortgages rather than government agency securities. International investment-grade debt represented 40.2% of Fund assets, while U.S. high-yield bonds accounted for 2.7% of Fund assets. U.S. Treasuries and government agency bonds accounted for 5.8% of Fund assets. The Fund's currency positioning, however, tended to hold back relative performance results during the 12-month period, as we overweighted the U.S. dollar, which weakened relative to the currencies of commodity-producing countries. Q What types of investments had notable impacts on the Fund's performance over the 12 months ended October 31, 2010? A The Fund's longer-duration positions in some sovereign government bonds of the United States, Germany and Japan all performed nicely as interest rates moved lower. Holdings in Canadian Housing Trust bonds also added to the Fund's performance results, as did investments in some high-coupon, U.S. Fannie Mae mortgage-backed debt. On the downside, the Fund did have an investment in short-duration German government securities, which underperformed. The Fund was underweighted, relative to the Barclays Index, in Spanish and Italian government bonds, but the small positions nevertheless held back the Fund's performance on an absolute basis. While the Fund's overall exposure to corporate bonds helped performance, an investment in the high-yield debt of First Data, a U.S. company specializing in processing electronic transactions, underperformed. Q Was the Fund's performance during the 12-month period materially affected by the use of derivatives as an investment strategy? A During part of the period, the Fund held an investment in a Japanese forward-currency contract. The position turned out to have a minor, negative influence on Fund performance. The Fund had maintained an overweighted exposure to the Japanese yen for most of the Fund's fiscal year and we invested in the forward-currency contract for part of the 12-month period to reduce the risks posed by the longer yen positioning. Even though the Japanese yen strengthened over the entire 12-month period ended October 31, 2010, it weakened during the period in which the Fund held the forward-currency contract. As a consequence, the use of the derivative investment slightly detracted from the Fund's overall performance results. 6 Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/10 Q What is your investment outlook? A We continue to favor corporate debt and other credit-sensitive securities, as their yield spreads (the difference in yields between higher- and lower-rated debt) still appear compelling relative to government securities, especially against a backdrop of improving economic conditions. We also are positive about the prospects for the U.S. dollar against foreign currencies, especially the euro. That is not our view of the currencies of commodity-exporting nations such as Canada and Australia, however, which we think have the potential to continue gaining against the dollar. We think that the dollar also may weaken against some emerging market currencies. In our duration management, we have positioned the Fund against the possibility of eventual increases in interest rates by establishing a relatively short duration in the United States, and by investing part of the Fund in floating-rate securities. We do expect interest rates to remain low for the next few months, however, as the Fed maintains its highly accommodative monetary policy. We expect that the Fed eventually will start raising rates, however, when signs of better employment conditions and inflationary pressures begin appearing. In managing the Fund, we have been avoiding investments in securities with maturities between two and five years, as they are particularly vulnerable to rising interest rates. Please refer to the Schedule of Investments on pages 16-32 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 the issuers of the underlying securities and their inability to meet their debt obligations. Prepayment risk is the chance that mortgage-backed bonds will be paid off early if falling interest rates prompt homeowners to refinance their mortgages. Forced to reinvest the unanticipated proceeds at lower interest rates, the Fund would experience a decline in income and lose the opportunity for additional price appreciation associated with falling interest rates. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. These risks may increase share price volatility. 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 | Annual Report | 10/31/10 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 Aggregate Bond Fund Based on actual returns from May 1, 2010, through October 31, 2010. - -------------------------------------------------------------------------------- Share Class A C Y - -------------------------------------------------------------------------------- Beginning Account Value $ 1,000.00 $ 1,000.00 $ 1,000.00 on 5/1/10 - -------------------------------------------------------------------------------- Ending Account Value $ 1,076.30 $ 1,072.54 $ 1,076.85 (after expenses) on 10/31/10 - -------------------------------------------------------------------------------- Expenses Paid During Period* $ 5.23 $ 9.93 $ 4.92 - -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.00%, 1.90%, and 0.94% for Class A, Class C, and Class Y shares respectively, multiplied by the average account value over the period, multiplied by 184/365. 14 Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/10 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.

The accompanying notes are an integral part of these financial statements. Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/10 39 Notes to Financial Statements | 10/31/10 1. Organization and Significant Accounting Policies Pioneer Global Aggregate Bond Fund (the Fund) is a series of Pioneer Series Trust VII, a Delaware statutory trust. The Fund is registered under the Investment Company Act of 1940 as a diversified, open-end management investment company. The investment objective of the Fund is to provide current income from an investment grade portfolio with due regard to preservation of capital and prudent investment risk. 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 rates of 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 from net investment income earned 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. Each share class has 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. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making the Fund 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 prospectus contains unaudited information regarding the Fund's principal risks. Please refer to that document 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 40 Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/10 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's financial statements have been prepared in conformity with U.S. generally accepted accounting principles that require the management of the Fund to, among other things, make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income, expenses and gain or loss on investments during the reporting period. Actual results could differ from those estimates. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements, which are consistent with those policies generally accepted in the investment company industry: A. Security Valuation Security transactions are recorded as of trade date. The net asset value of the Fund is computed once daily, on each day the New York Stock Exchange (NYSE) is open, as of the close of regular trading on the NYSE. Fixed income securities with remaining maturity of more than sixty days are valued at prices supplied by independent pricing services, which consider such factors as market prices, market events, quotations from one or more brokers, Treasury spreads, yields, maturities and ratings. Valuations may be supplemented by dealers and other sources, as required. Equity securities that have traded on an exchange are valued at the last sale price on the principal exchange where they are traded. Equity securities that have not traded on the date of valuation, or securities for which sale prices are not available, generally are valued using the mean between the last bid and asked prices. Securities for which independent pricing services are unable to supply prices or for which market prices and/or quotations are not readily available or are considered to be unreliable are valued using fair value methods pursuant to procedures adopted by the Board of Trustees. The Fund may use fair value methods if it is determined that a significant event has occurred after the close of the exchange or market on which the security trades and prior to the determination of the Fund's net asset value. Thus, the valuation of the Fund's securities may differ from exchange prices. At October 31, 2010, there were no securities that were valued using fair value methods (other than securities valued using prices supplied by independent pricing services). Inputs used when applying fair value methods to value a security may include credit ratings, the financial condition of the company, current market conditions and comparable securities. Short-term fixed income securities with remaining maturities of sixty days or less generally are valued at amortized cost. Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/10 41 Principal amounts of mortgage-backed securities are adjusted for monthly paydowns. Premiums and discounts related to certain mortgage-backed securities are amortized or accreted in proportion to the monthly paydowns. All discounts/premiums on debt securities are accreted/amortized for financial reporting purposes over the life of the respective securities, and such accretion/amortization is included in interest income. 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 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. 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). 42 Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/10 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, or as from paid-in capital, depending on the type of book/tax differences that may exist. At October 31, 2010, the Fund has reclassified $27,565 to decrease undistributed net investment income and $27,565 to increase accumulated net realized gain on investments, to reflect permanent book/tax differences. The reclassification has no impact on the net assets of the Fund and presents the Fund's capital accounts on a tax basis. The tax character of distributions paid during the years ended October 31, 2010 and October 31, 2009 were as follows: - -------------------------------------------------------------------------- 2010 2009 - -------------------------------------------------------------------------- Distributions paid from: Ordinary income $412,471 $277,723 Long-term capital gain 12,702 -- Distribution in excess of net investment income 17,692 -- - -------------------------------------------------------------------------- Total $442,865 $277,723 ========================================================================== The following shows the components of distributable earnings on a federal income tax basis at October 31, 2010: - ------------------------------------------------ 2010 Distributable earnings: Current year dividend payable $ (21,300) Unrealized appreciation 1,009,483 - ------------------------------------------------ Total $ 988,183 ================================================ 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 approximately $2,228 in underwriting commissions on the sale of Class A shares during the year ended October 31, 2010. Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/10 43 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 its 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 shares of the Fund, respectively (see Note 4). Class Y shares do not pay distribution fees. All expenses and fees paid to the transfer agent, Pioneer Investment Management Shareholder Services, Inc. (PIMSS), for its services which are allocated among the classes of shares 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 net investment income dividends to Class A, Class C, and Class Y shares can reflect 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 investments. Credit Suisse AG, 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 payments in lieu of dividends or interest 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. If the required market value of the collateral is less than the value of the loaned securities, the borrower is required to deliver additional collateral for the account of the Fund prior to the close of business on that day. 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 is required to return the cash collateral to the borrower and could suffer a loss if the value of the collateral, as invested, has declined. 44 Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/10 H. Futures Contracts The Fund may enter into futures transactions to hedge against changes in interest rates, securities prices and currency exchange rates or to seek to increase total return. Futures contracts are types of derivatives. All futures contracts entered into by the Fund are traded on a futures exchange. 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. Futures contracts are subject to market risk, interest rate risk and currency exchange rate risk. 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. With futures, there is minimal counterparty credit risk to the Fund since futures are exchange-traded and the exchange's clearinghouse, as counterparty to all exchange-traded futures, guarantees the futures against default. At October 31, 2010, there were no open futures contracts. 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 equal to or in excess of the repurchase price. The collateral for all repurchase agreements is held in safekeeping in the customer-only account of the Fund's custodian or a subcustodian of the Fund. 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.

Subsequent Events In preparing these financial statements, PIM has evaluated the impact of all events and transactions for potential recognition or disclosure and has determined that there were no subsequent events requiring recognition or disclosure in the financial statements. 48 Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/10 Report of Independent Registered Public Accounting Firm To the Board of Trustees of Pioneer Series Trust VII and the Shareowners of Pioneer Global Aggregate Bond Fund - -------------------------------------------------------------------------------- We have audited the accompanying statement of assets and liabilities of Pioneer Global Aggregate Bond Fund (the "Fund") (one of the portfolios constituting the Pioneer Series Trust VII), including the schedule of investments, as of October 31, 2010, and the related statements of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended and the financial highlights for each of the periods indicated therein. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Fund's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of October 31, 2010, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Pioneer Global Aggregate Bond Fund at October 31, 2010, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the periods indicated therein, in conformity with U.S. generally accepted accounting principles. /s/ Ernst & Young LLP Boston, Massachusetts December 28, 2010 Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/10 49 ADDITIONAL INFORMATION (unaudited) The percentages of the Fund's ordinary income distributions that are exempt from nonresident alien (NRA) tax withholding resulting from qualified interest income and qualified short term gains were 68.42% and 0.0%, respectively. 50 Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/10 Trustees, Officers and Service Providers Investment Adviser Pioneer Investment Management, Inc.

But with the memory of a deep recession still lingering, businesses and consumers remained cautious about both investing and spending. While business fundamentals showed signs of improvement, there was still a reluctance to hire, and high unemployment remains a problem. Wary investors, concerned about risk, gravitated towards cash and bonds. We remain generally optimistic about the prospects for economic recovery, although it may occur more slowly than many would like. At Pioneer, we have long advocated the benefits of staying diversified and investing for the long term. This strategy has generally performed well for many investors. Bond markets certainly rewarded investors in the first nine months of 2010. While the equity markets barely budged, equities at the end of September 2010 were inexpensive relative to bonds, compared with historic levels, and represented potentially good value for long-term investors. Pioneer has not changed the basic approach to investing that we have used for more than 80 years. We remain focused on company fundamentals and risk management. Our investment process is based on careful research into individual companies, 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. Our experienced professionals devote themselves to the careful research needed to identify investment opportunities in markets around the world. Our advice, as always, is to work closely with a trusted financial advisor to discuss your goals and work together to develop an investment strategy that meets your individual needs. There is no single best strategy that works for every investor. 2 Pioneer Global High Yield Fund | Annual Report | 10/31/10 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. We greatly appreciate your trust in us and we thank you for investing with Pioneer. Sincerely, /s/ Daniel K. Kingsbury Daniel K. Kingsbury President and CEO Pioneer Investment Management USA Inc.

Pioneer Global High Yield Fund | Annual Report | 10/31/10 3 Portfolio Management Discussion | 10/31/10 High-yield debt investments continued their robust rebound in markets throughout the world over the 12 months ended October 31, 2010, despite some periodic bouts of volatility, as investors tried to determine the strength and persistency of the global economic recovery. In the following interview, Andrew Feltus discusses the factors that influenced the performance of Pioneer Global High Yield Fund during the 12-month period. Mr. Feltus, senior vice president, is a member of Pioneer's fixed-income team and is responsible for the day-to-day management of the Fund. He is supported by Tracy Wright, vice president, also a member of Pioneer's fixed-income team. Q How did the Fund perform during the 12 months ended October 31, 2010? A Pioneer Global High Yield Fund Class A shares returned 21.16% at net asset value over the 12 months ended October 31, 2010, while the Fund's benchmarks, the Bank of America Merrill Lynch (BofA ML) Global High Yield and Emerging Markets Plus Index and the BofA ML High Yield Master II Index, returned 17.61% and 19.26%, respectively. Over the same period, the average return of the 483 mutual funds in Lipper's High Current Yield Funds category was 17.82%. On October 31, 2010, the 30-day SEC yield on the Fund's Class A shares was 6.76%. Q How would you describe the conditions for high-yield investing during the 12 months ended October 31, 2010? A The recovery by corporate bonds and other credit-sensitive investments, which began in 2009, continued over most of the 12-month period, despite some short-term interruptions that occurred when periodic doubts resurfaced about the resiliency of the economic rebound. The most significant market pullback began in the early spring of 2010 and persisted through the early summer, as it became clear that the strong economic rebound of late 2009 and early 2010 was starting to weaken. Corporations, after aggressively building up their inventories, became somewhat more cautious at the same time that many consumers focused on paying down debts rather than accumulating new possessions. Meanwhile, some of the effects of the U.S. government's stimulus spending began tapering off. Market trends reversed, however, after Federal Reserve Board (the Fed) Chairman Ben Bernanke, in August 2010, outlined new plans to inject more liquidity into the market. Investors again became attracted to corporate securities, including high-yield bonds and stocks. Supporting the resurgence 4 Pioneer Global High Yield Fund | Annual Report | 10/31/10 were new reports of improving corporate profits as well as growing sentiments that the November mid-term elections would lead to more business-friendly U.S. economic policies. Q What allocation decisions led to the Fund's strong performance relative to its benchmarks over the 12 months ended October 31, 2010? A The Fund performed very well during the 12-month period, surpassing the BofA ML benchmarks for both domestic and global and emerging markets high-yield investing. Security selection was the principal factor driving the Fund's outperformance. We have paid special attention, especially since the steep market declines in 2008, to analyzing high-yield corporate bonds in an effort to identify what securities may have been unfairly penalized by the market. The analysis reaped rewards during the rebound in high-yield debt, when the market recognized the value in many of the bonds in which we had invested the Fund's assets. Throughout the 12-month period ended October 31, 2010, the Fund had a heavy emphasis on U.S. high-yield securities, which outperformed most other segments of the fixed-income market. Part of the Fund's allocation to U.S. high-yield securities was a position in non-government-agency mortgage-backed securities, which performed particularly well and provided further support to the Fund's relative performance results. While we underweighted the Fund to emerging market government bonds, we overweighted emerging market corporates, and that positioning also made a favorable contribution to the Fund's performance results. The Fund had a small position in convertible securities, which gave the portfolio exposure to the performance in the equity market. The Fund also had a focus on the currencies of emerging market countries such as Brazil, Colombia, Argentina and Turkey; that also helped performance, as those currencies benefited from the strong growth of their national economies. At the same time, we underweighted the Fund in the euro and in euro-denominated securities, which supported the Fund's performance when the euro fell this past spring and summer on news of the extent of the government debt problems in Greece, Spain, Ireland and several other European nations. The underweighted position in the euro had a favorable impact on the Fund's relative performance for the overall 12-month period ended October 31, 2010, but it was a drag on performance results over the final two months of the Fund's fiscal year, when the euro started rallying. One allocation that had a positive impact on absolute results but that nevertheless held back benchmark-relative performance was the Fund's position in floating-rate bank loans. The loans, which had lower yields than most of Pioneer Global High Yield Fund | Annual Report | 10/31/10 5 the Fund's investments, clearly lagged the rest of the high-yield market during the period. That should not have been surprising during a period when high-yield securities performed very well and when interest rates tended to decline. We continue to be interested in bank loans as a more defensive part of the Fund's portfolio. They also help protect the Fund against rising interest rates, as their yields generally start increasing as interest rates move higher. At the end of the Fund's fiscal year on October 31, 2010, 69.5% of Fund assets were invested in U.S. high-yield securities, with 22.5% invested in emerging markets and 7.0% in international high-yield debt. Q What types of individual investments most influenced the Fund's performance over the 12 months ended October 31, 2010? A While the Fund was underexposed to the automobile industry generally, it did have an investment in the convertible securities of Ford Motor, which performed particularly well, doubling in value since we initiated the position in the fall of 2009. In addition, the Fund's investment in the convertible securities of WESCO International, a leading distributor of electrical and industrial supplies, also gave a boost to performance. Among emerging markets investments, the Fund's position in the securities of True Move, a Thai wireless communication company, was a standout performer. Many companies paid down their outstanding debt during the 12-month period, buying back bonds at a profit to the Fund. These included: Accellent; Hexion Specialty Chemicals; Delta Airlines; Knology; Cellu Tissue; and Impress Metal Packaging. Despite the overall strong performance results, the Fund did have a few disappointments during the 12-month period. One notable disappointment was a small position in the bonds of Independencia, a Brazilian beef company that defaulted on its debt even after restructuring in 2009. Bonds of the Mashantucket Native American tribe, linked to the Foxwoods Casino complex in Connecticut, also defaulted, resulting in a small loss to the Fund. In addition, while Sitel, an operator of call centers, did not default on its bonds, the securities lost value after the company reported disappointing earnings for the second quarter of 2010. Since then, the company has reported improving profits for the third quarter and the bonds have recovered some of their value. Q What is your investment outlook? A Even after rallying strongly for more than a year, high-yield bonds still appear reasonably priced (in comparison with long-term historical averages) and inexpensive relative to their very low default rates. The key to performance over the next several months, we think, will be highly affected by what Treasuries do. If Treasury rates do not spike up and thereby tighten the 6 Pioneer Global High Yield Fund | Annual Report | 10/31/10 yield spreads (the yield differences between higher- and lower-rated debt), high-yield bonds should continue to perform well against a backdrop of improving corporate profits and generally healthy corporate balance sheets. We do not anticipate that the Fed will move to raise short-term interest rates in the next six months, as the nation's central bankers are waiting either for the employment picture to improve or for signs of increasing inflationary pressures to begin to appear. Given all these factors, we remain positive about the high-yield market. Please refer to the Schedule of Investments on pages 17-56 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 securities 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. 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.

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.

Pioneer Global High Yield Fund | Annual Report | 10/31/10 15 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. The Fund is 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. Class Z shares were first publicly offered on July 6, 2007. Effective December 31, 2009, Class B shares are no longer offered to new or existing shareholders, except that dividends and/or capital gain distributions may continue to be reinvested in Class B shares, and shareholders may exchange their Class B shares for Class B shares of other Pioneer funds, as permitted by existing exchange privileges. 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 rates of 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 from net investment income earned 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. Each share class has 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 or Class Z shares. Class B shares convert to Class A shares approximately eight years after the date of purchase. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making the Fund 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 prospectus contains unaudited 66 Pioneer Global High Yield Fund | Annual Report | 10/31/10 information regarding the Fund's principal risks. Please refer to that document when considering the Fund's principal risks. 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. 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. Senior floating rate loan interests (senior loans) are valued in accordance with guidelines established by the Board of Trustees at the mean between the last available bid and asked prices from one or more brokers or dealers as obtained from Loan Pricing Corporation. Senior loans for which no reliable price quotes are available will be valued by Loan Pricing Corporation through the use of pricing matrices to determine valuations. Fixed income securities with remaining maturity of more than sixty days are valued at prices supplied by independent pricing services, which consider such factors as market prices, market events, quotations from one or more brokers, Treasury spreads, yields, maturities and ratings. Valuations may be supplemented by dealers and other sources, as required. 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. Equity securities that have traded on an exchange are valued at the last sale price on the principal exchange where Pioneer Global High Yield Fund | Annual Report | 10/31/10 67 they are traded. Equity securities that have not traded on the date of valuation, or securities for which sale prices are not available, generally are valued using the mean between the last bid and asked prices. Securities or loans for which independent pricing services are unable to supply prices or for which market prices and/or quotations are not readily available or are considered to be unreliable are valued using fair value methods pursuant to procedures adopted by the Board of Trustees. Trading in foreign securities is substantially completed each day at various times prior to the close of the NYSE. The values of such securities used in computing the net asset value of the Fund's shares are determined as of such times. The Fund may use fair value methods if it is determined that a significant event has occurred after the close of the exchange or market on which the security trades and prior to the determination of the Fund's net asset value. Thus, the valuation of the Fund's securities may differ from exchange prices. At October 31, 2010, seven securities were valued using fair value methods (in addition to securities valued using prices supplied by independent pricing services) representing 0.67% of net assets. Inputs used when applying fair value methods to value a security may include credit ratings, the financial condition of the company, current market conditions and comparable securities. Short-term fixed income securities with remaining maturities of sixty days or less generally are valued at amortized cost. Money market mutual funds are valued at net asset value. Principal amounts of mortgage-backed securities are adjusted for monthly paydowns. Premiums and discounts related to certain mortgage-backed securities are amortized or accreted in proportion to the monthly paydowns. All discounts/premiums on debt securities are accreted/amortized for financial reporting purposes over the life of the respective securities, and such accretion/amortization is included in interest income. Interest income is recorded on the accrual basis, net of unrecoverable foreign taxes withheld at the applicable country rates. 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, 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. 68 Pioneer Global High Yield Fund | Annual Report | 10/31/10 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. 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. 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. At October 31, 2010, the Fund had a net capital loss carryforward of $289,329,562 of which the following amounts will expire between 2016 and 2018 if not utilized: $58,199,667 in 2016, $204,858,985 in 2017 and $26,270,910 in 2018. Pioneer Global High Yield Fund | Annual Report | 10/31/10 69 At October 31, 2010, the Fund reclassified $1,472,184 to decrease undistributed net investment income and $1,472,184 to increase accumulated net realized loss on investments to reflect permanent book/tax differences. The reclassification has no impact on the net assets of the Fund and presents the Fund's capital accounts on a tax-basis. The tax character of distributions paid during the years ended October 31, 2010 and October 31, 2009 was as follows: ---------------------------------------------------------------------------- 2010 2009 ---------------------------------------------------------------------------- Distributions paid from: Ordinary income $163,595,781 $169,500,334 ---------------------------------------------------------------------------- Total $163,595,781 $169,500,334 ---------------------------------------------------------------------------- The following shows the components of distributable earnings on a federal income tax-basis at October 31, 2010: ---------------------------------------------------------------------------- 2010 ---------------------------------------------------------------------------- Distributable earnings: Undistributed ordinary income $ 4,565,988 Capital loss carryforward (289,329,562) Current year dividend payable (3,361,514) Unrealized appreciation 68,413,126 ---------------------------------------------------------------------------- Total $ (219,711,962) ---------------------------------------------------------------------------- The difference between book-basis and tax-basis unrealized appreciation is attributable to the tax deferral of losses on wash sales, adjustments relating to catastrophe bonds, and the tax-basis adjustments 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 $228,753 in underwriting commissions on the sale of Class A shares during the year ended October 31, 2010. 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 its 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 shares of the Fund, respectively (see Note 4). Class Y and Class Z shares do not pay distribution fees. All 70 Pioneer Global High Yield Fund | Annual Report | 10/31/10 expenses and fees paid to the transfer agent, Pioneer Investment Management Shareholder Services, Inc. (PIMSS), for its services are allocated among the classes of shares 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 net investment income dividends to Class A, Class B, Class C, Class Y and Class Z shares can reflect 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 equal to or in excess of the repurchase price. The collateral for all repurchase agreements is held in safekeeping in the customer-only account of the Fund's custodian or a subcustodian of the Fund. 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 investments. Credit Suisse AG, 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 payments in lieu of dividends or interest 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. If the required market value of the collateral is less than the value of the loaned securities, the borrower is required to deliver additional collateral for the account of the Fund prior to the close of business on that day. The Fund has the right, under the lending agreement, to terminate the loan and recover the securities from the Pioneer Global High Yield Fund | Annual Report | 10/31/10 71 borrower with prior notice. The Fund is 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. When the Fund is a seller of protection, the Fund would be required to pay the notional (or other agreed-upon) value of the referenced debt obligation to the counterparty in the event of a default by a U.S. or foreign corporate issuer of a debt obligation, which would likely result in a loss to the Fund. In return, the Fund would receive from the counterparty a periodic stream of payments during the term of the contract provided that no event of default occurred. The maximum exposure of loss to the Fund as seller of protection 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 described 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. 72 Pioneer Global High Yield Fund | Annual Report | 10/31/10 The Fund had no credit default swap contracts in the portfolio at October 31, 2010. 2. Management Agreement 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% of the next $500 million; and 0.45% of the excess over $2 billion. For the year ended October 31, 2010, the effective management fee (excluding waivers and/or assumption of expenses) was equivalent to 0.61% of the average daily net assets. PIM has contractually agreed to limit ordinary operating expenses to the extent required to reduce Fund expenses to 1.10%, 2.00%, 2.00% and 0.90% of the average daily net assets attributable to Class A, Class B, Class C and Class Z shares, respectively. These expense limitations are in effect through March 1, 2012 for Class A, Class B, Class C and Class Z shares. There can be no assurance that PIM will extend the expense limitation agreement for a class of shares beyond the date referred to above. 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 as administrative reimbursements. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $134,847 in management fees, administrative costs and certain other reimbursements payable to PIM at October 31, 2010. 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 reimburses PIMSS for out-of-pocket expenses incurred by PIMSS related to shareholder activities such as proxy and statement mailings, outgoing phone calls and omnibus relationship contracts. For the year ended October 31 2010, such out-of-pocket expenses by class of shares were as follows: - ------------------------------------------------------------------------------- Shareholder Communications: Class A $ 855,207 Class B 47,441 Class C 232,908 Class Y 194,013 Class Z 1,863 - ------------------------------------------------------------------------------- Total $1,331,432 =============================================================================== Pioneer Global High Yield Fund | Annual Report | 10/31/10 73 Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $303,634 in transfer agent fees and out-of-pocket reimbursements payable to PIMSS at October 31, 2010. 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, Class B 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 also 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. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $72,407 in distribution fees payable to PFD at October 31, 2010. 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 (within 12 months for purchases made on or after April 1, 2009). 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. Shares purchased as part of an exchange remain subject to any CDSC that applied to the original purchase of those shares. There is no CDSC for Class Y or Class Z shares. Proceeds from the CDSCs are paid to PFD. For the year ended October 31, 2010, CDSCs in the amount of $354,112 were paid to PFD. 5. Line of Credit Facility The Fund, along with certain other funds in the Pioneer Family of Funds (the Funds), participates 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 the amount available under the facility or the limits set for borrowing by the Fund's prospectus and the 1940 Act. Interest on borrowings is payable at the higher of the London Interbank Offered Rate (LIBOR) on the borrowing date plus 1.25% on an annualized basis or the Federal Funds Rate on the borrowing date plus 1.25% on an annualized basis. The Funds pay an annual commitment fee for this facility. 74 Pioneer Global High Yield Fund | Annual Report | 10/31/10 The commitment fee is allocated among participating Funds based on an allocation schedule set forth in the credit agreement. For the year ended October 31, 2010, the average daily amount of borrowings outstanding during the period was $6,435,414. The related weighted average annualized interest rate for the period was 1.52%, and the total interest expense on such borrowings was $157,840. As of October 31, 2010, there were no borrowings outstanding. 6. 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.

These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Fund's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of October 31, 2010, by correspondence with the custodian, brokers and agent banks or by other appropriate auditing procedures where replies from brokers and agent banks were not received. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Pioneer Global High Yield Fund at October 31, 2010, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the periods indicated therein, in conformity with U.S. generally accepted accounting principles.

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.
