The economy went through a soft patch in the first half, and the second half, so far, has been highlighted by the U.S. government's battle over the debt ceiling and Standard & Poor's downgrade of the U.S. Treasury's credit rating from the top rating of "AAA" for the first time in history. After rallying nicely in the first half, U.S. equity markets reacted sharply this summer to the political stalemate and the downgrade. There has been continued pressure on equities due to concerns about the growing European sovereign-debt crisis and its potential impact on the global economy. Despite legitimate reasons for concern, we believe there are also reasons for optimism that the U.S. economy will continue to exhibit modest growth and is not headed into a severe recession. Corporations continue to post solid earnings and, for the most part, are maintaining their positive earnings outlooks. They also have strong balance sheets with improved net leverage and high cash levels. Auto production has rebounded following the Japanese supply-chain interruptions caused by the earthquake and tsunami last spring. Retail sales growth year-over-year has remained steady despite low consumer confidence. And despite high unemployment in the U.S., private sector employment has grown consistently, albeit modestly, since February 2010. There are certainly risks to our outlook, including possible contagion from the European sovereign-debt and banking crisis, the fiscal drag from federal and state budget cuts in the U.S., as well as potential "negative feedback loops" from capital-market volatility. But broadly speaking, we think the subpar economic recovery is consistent with recoveries from other "balance sheet"-caused recessions. The difficult recovery process has been accompanied by wide market swings. While this is a challenging environment, our investment professionals continue to focus on finding good opportunities to invest in both equity and bond markets using the same disciplined approach Pioneer has used since 1928. Our approach is to identify undervalued individual securities with the greatest potential for success, carefully weighing risk against reward. Our teams of investment professionals continually monitor and analyze the relative valuations of different sectors and securities globally to help build portfolios that we believe can help you achieve your investment goals. 2 Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/11 At Pioneer, we have long advocated the benefits of staying diversified and investing for the long term. The strategy has generally performed well for many investors. 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. 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 us.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 | 10/31/11 3 Portfolio Management Discussion | 10/31/11 Global fixed-income investments generally delivered positive results for the 12 months ended October 31, 2011, despite significant changes and even turmoil in the market environment. Over the period, investors weighed the sometimes competing effects of persistent growth trends and rising concerns about the credit-worthiness of some European sovereign bonds. In the following interview, Charles Melchreit discusses the performance of Pioneer Global Aggregate Bond Fund during the 12 months ended October 31, 2011. Mr. Melchreit, vice president and portfolio manager at Pioneer, is responsible for the daily management of the Fund, along with Mr. Tanguy Le Saout, Head of Government Bond and Value-at-Risk Portfolios for Pioneer in Europe. Q How did the Fund perform over the 12 months ended October 31, 2011? A Pioneer Global Aggregate Bond Fund Class A shares returned 3.22% at net asset value over the 12 months ended October 31, 2011, while the Fund's benchmark, the Barclays Capital Global Aggregate Bond Index (the Barclays Index), returned 4.07%. Over the same period, the average total return of the 167 mutual funds in Lipper's Global Income Funds category was 2.41%. At the end of the period, on October 31, 2011, the 30-day standardized SEC yield of the Fund's Class A shares was 2.62% with fees waived, and 1.99% without fees waived. Q What was the investment environment like for fixed-income securities over the 12 months ended October 31, 2011? A Over the first six months of the period, the improving global economy led to solid performance by credit-sensitive securities, including corporate bonds and commercial mortgage-backed and asset-backed securities. The environment shifted, however, during the final six months of the period as investors grew more averse to credit risk and to any exposure to the sovereign-debt problems of some European nations, particularly Greece and Italy. As the countries struggled with their national debt and appealed for assistance for some type of financial relief, investors began realizing that sovereign-debt investments were not risk-free. At the same time, political disagreements in the United States about fiscal and monetary policies raised worries about the ability of government leaders in the U.S. to make decisions about economic issues. The worries increased sharply in the summer of 2011 when Congress and the Obama administration staged a contentious debate over raising the nation's debt ceiling. Almost immediately following the debate, the Standard & Poor's (S&P) rating agency lowered the AAA rating of U.S. Treasury securities for the first time since one of S&P's predecessor firms assigned the AAA rating to the U.S. in 4 Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/11 1917. In reaction, investor confidence in the health of the economy fell, causing a general flight to perceived quality and away from credit risk. Almost paradoxically, despite the ratings downgrade by S&P, U.S. Treasuries outperformed during the investor flight to quality and away from credit risk. Q How did the Fund's positioning affect its performance relative to the benchmark Barclays Index in the changing investment environment characterizing the 12 months ended October 31, 2011? A In the first half of the Fund's fiscal year, overweighted positions in corporate bonds and other credit-sensitive securities, combined with an underweighting of U.S. Treasuries, resulted in solid relative performance. In the second half of the period, however, the Fund's benchmark-relative performance was held back by our emphasis on the credit sectors and a portfolio underweighting of the perceived safest government bonds--those of the United States and Germany. The global flight to quality during the period also resulted in the appreciation of the Japanese yen, and the Fund's low exposure to that currency also detracted from benchmark-relative results. However, the Fund's lack of any exposure to Greece and its low exposure to Italy tended to help relative performance, although one of the Fund's Italian government bond holdings actually gained ground amid the turmoil. Q How did the Fund's currency positioning affect its performance over the 12 months ended October 31, 2011? A Currency often is the major performance driver of investments in global investment-grade securities. Over the 12-month period ended October 31, 2011, global currency markets were particularly volatile. Throughout the period, we maintained an overweighted portfolio position in the U.S. dollar (USD). The USD positioning tended to hurt the Fund's relative performance when the dollar declined in value compared with major foreign currencies in the first half of the Fund's fiscal year. But the focus on the USD in the portfolio tended to support performance in the final six months of the Fund's fiscal year as the dollar gained against the euro and many emerging market currencies. In addition, performance was also helped by the Fund's exposure to commodity-linked currencies, such as those of Canada, Australia and Norway. Q How did the Fund's exposure to interest-rate changes affect its performance over the 12 months ended October 31, 2011? A Overall, the Fund's duration positioning generated mixed results over the 12-month period, helping performance in the first half of the Fund's fiscal year and detracting from performance in the second half. Because we were concerned that interest rates would begin to rise and thus cut into the value Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/11 5 of longer-maturity, high-quality bonds, we maintained a generally shorter duration in the Fund's portfolio than that of the Barclays Index benchmark throughout the full 12-month period. (Duration is a measure of a portfolio's price sensitivity to changes in interest rates.) As noted previously, the shorter duration positioning helped the Fund's performance in the first half of the fiscal year, but did not help in the second half of the year when rising concerns about inflation led to stronger performance from longer-maturity government securities of the United Kingdom, Germany and Canada, where central banks tightened monetary policy and raised short-term rates. Those negative effects were partially offset by the fact that the Fund had a somewhat longer duration positioning in U.S. Treasuries, which tended to rally during the general flight to quality in the second half of the Fund's fiscal year. Q How did sector positioning affect the Fund's performance over the 12 months ended October 31, 2011? A The Fund's overall underweight positioning in sovereign government bonds helped support results, especially given the lack of portfolio exposure to any Greek government bonds and limited exposure to the bonds of Portugal, Spain and Italy. We added positions in Irish government bonds during the final six months of the period, and that also supported relative performance as the market reacted favorably to the Irish government's financial reform measures. Holding back results, however, was our decision to invest the Fund in some higher-quality emerging market sovereigns, notably bonds of Indonesia and Singapore. The bonds underperformed when emerging markets fell out of favor in the closing months of the 12-month period. The Fund's very low exposure to high-yield corporate bonds helped performance as the sector performed poorly over the second half of the annual reporting period. Just 5.3% of the Fund's net assets were invested in domestic high-yield bonds at the end of the period on October 31, 2011. Among the Fund's investment-grade holdings, an overweight position in industrial bonds, combined with good security selection in the group, supported results, as did a slight overweight and good security selection in the utilities sector. The Fund's significant overweight in the financials sector was a major performance booster, especially when combined with good security selection in the group. Our decision to avoid European banks helped protect the Fund from the market's severe reaction to the European sovereign-debt problems. Lastly, although the Fund's underweighted position in government agency mortgages served as a drag on performance, those effects were offset by the positive contributions from out-of- benchmark investments in commercial mortgage-backed securities. 6 Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/11 Q What is your investment outlook? A We expect the global economic recovery to continue, despite recent problems, and we anticipate maintaining an emphasis on credit-sensitive securities in the Fund--including investment-grade corporate bonds--in the coming months. Despite our general view, we believe Europe may fall into recession and we continue to underweight the portfolio in the euro. We think Europe's problems are more the result of dysfunctional politics than underlying economic problems. In searching for investment opportunities for the Fund in Europe, we expect to maintain our focus on countries whose economies are less dependent on the euro currency, such as the Scandinavian countries, and the United Kingdom and Poland. Although the tightening monetary policies of the Chinese government have raised concerns about a downturn in that country, which would have a major impact on the global economy, we believe Chinese authorities have shown a willingness to change direction if their economy appears to be weakening too much. Outside China, we favor investments in Asian countries such as Indonesia, which in general have stronger balance sheets than most European nations and have been successful in developing sustainable domestic markets. Despite the volatility that seems to be inherent in emerging markets, we think the better-quality emerging Asian economies are becoming increasingly reliable places in which to invest. We are watching interest-rate trends carefully. The U.S. Federal Reserve Board has signaled its intention to keep short-term rates low for the foreseeable future, but we think longer-term rates eventually should start to rise over time. The situation in Europe is changing, as the European Central Bank recently has shown a new willingness to reduce interest rates in response to threats of an impending recession.

Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/11 7 The portfolio may invest in mortgage-backed securities, which during times of fluctuating interest rates may increase or decrease more than other fixed-income securities. Mortgage-backed securities are also subject to pre-payments. The portfolio may invest in derivative securities, which may include futures and options. These types of instruments can increase price fluctuation. 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. 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. Investments in high yield or lower-rated securities are subject to greater-than-average risk. Investing in foreign and/or emerging market securities involves risks relating to interest rates, currency exchange rates, economic, and political conditions. 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 | 10/31/11 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, 2011, through October 31, 2011. -------------------------------------------------------------------------------- Share Class A C Y -------------------------------------------------------------------------------- Beginning Account Value $1,000.00 $1,000.00 $1,000.00 on 5/1/11 -------------------------------------------------------------------------------- Ending Account Value $1,008.50 $1,004.02 $1,012.70 (after expenses) on 10/31/11 -------------------------------------------------------------------------------- Expenses Paid During Period* $5.06 $9.60 $4.16 -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.00%, 1.90%, and 0.82% 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 | 10/31/11 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 | 10/31/11 45 Notes to Financial Statements | 10/31/11 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. 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 46 Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/11 (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. Short-term fixed income securities with remaining maturities of sixty days or less generally are valued at amortized cost. 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. Examples of a significant event might include political or economic news, corporate restructurings, natural disasters, terrorist activity or trading halts. Thus, the valuation of the Fund's securities may differ from exchange prices. At October 31, 2011, 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. 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. Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/11 47 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). 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 federal and state 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. 48 Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/11 Under the recently enacted Regulated Investment Company Modernization Act of 2010, the Fund will be permitted to carry forward capital losses incurred in taxable years beginning after December 22, 2010 for an unlimited period. However, any losses incurred during those future years will be required to be utilized prior to the losses incurred in pre-enactment tax years. As a result of this ordering rule, pre-enactment capital loss carryforwards may be more likely to expire unused. Additionally, post-enactment capital losses that are carried forward will retain their character as either short-term or long-term capital losses rather than being considered all short-term as under previous law. At October 31, 2011, the Fund reclassified $37,401 to increase distributions in excess of net investment income and $37,401 to increase accumulated net realized gain on investments, futures contracts and foreign currency transactions, 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, 2011 and October 31, 2010 were as follows: ----------------------------------------------------------------------------- 2011 2010 ----------------------------------------------------------------------------- Distributions paid from: Ordinary income $493,109 $412,471 Long-term capital gain -- 12,702 Distribution in excess of net investment income -- 17,692 ----------------------------------------------------------------------------- Total $493,109 442,865 ============================================================================= The following shows the components of distributable earnings on a federal income tax basis at October 31, 2011: ---------------------------------------------- 2011 ---------------------------------------------- Distributable earnings: Undistributed ordinary income $25,553 Undistributed long-term gain 45,360 Current year dividend payable (29,327) Unrealized appreciation 1,060,648 ---------------------------------------------- Total $1,102,234 ============================================== The difference between book-basis and tax-basis net unrealized loss is attributable to the tax deferral of losses on wash sales, adjustments relating to catastrophe bonds, the mark to market on foreign currency and futures contracts, interest on defaulted bonds and interest accruals on preferred stock. Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/11 49 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 $3,747 in underwriting commissions on the sale of Class A shares during the year ended October 31, 2011. 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 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. Risks 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 50 Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/11 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. 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 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. 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 Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/11 51 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. The number of contracts open for eight months in the period ended October 31, 2011 was 1. There were no open futures contracts at October 31, 2011. J. 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. Fees waived and expenses reimbursed during the year ended October 31, 2011 are reflected on the Statement of Operations. These expense limitations are in effect through March 1, 2013 for Class A and Class C 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 $1,285 in management fees, administrative costs and certain other reimbursements payable to PIM at October 31, 2011. 3.

Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/11 55 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, 2011, 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, 2011, 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, 2011, 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 23, 2011 56 Pioneer Global Aggregate Bond Fund | Annual Report | 10/31/11 ADDITIONAL INFORMATION (unaudited) The percentage of the Fund's ordinary income distributions that are exempt from nonresident alien (NRA) tax withholding resulting from qualified interest income was 65.19%.

The economy went through a soft patch in the first half, and the second half, so far, has been highlighted by the U.S. government's battle over the debt ceiling and Standard & Poor's downgrade of the U.S. Treasury's credit rating from the top rating of "AAA" for the first time in history. After rallying nicely in the first half, U.S. equity markets reacted sharply this summer to the political stalemate and the downgrade. There has been continued pressure on equities due to concerns about the growing European sovereign-debt crisis and its potential impact on the global economy. Despite legitimate reasons for concern, we believe there are also reasons for optimism that the U.S. economy will continue to exhibit modest growth and is not headed into a severe recession. Corporations continue to post solid earnings and, for the most part, are maintaining their positive earnings outlooks. They also have strong balance sheets with improved net leverage and high cash levels. Auto production has rebounded following the Japanese supply-chain interruptions caused by the earthquake and tsunami last spring. Retail sales growth year-over-year has remained steady despite low consumer confidence. And despite high unemployment in the U.S., private sector employment has grown consistently, albeit modestly, since February 2010. There are certainly risks to our outlook, including possible contagion from the European sovereign-debt and banking crisis, the fiscal drag from federal and state budget cuts in the U.S., as well as potential "negative feedback loops" from capital-market volatility. But broadly speaking, we think the subpar economic recovery is consistent with recoveries from other "balance sheet"-caused recessions. The difficult recovery process has been accompanied by wide market swings. While this is a challenging environment, our investment professionals continue to focus on finding good opportunities to invest in both equity and bond markets using the same disciplined approach Pioneer has used since 1928. Our approach is to identify undervalued individual securities with the greatest potential for success, carefully weighing risk against reward. Our teams of investment professionals continually monitor and analyze the relative valuations of different sectors and securities globally to help build portfolios that we believe can help you achieve your investment goals. 2 Pioneer Global High Yield Fund | Annual Report | 10/31/11 At Pioneer, we have long advocated the benefits of staying diversified and investing for the long term. The strategy has generally performed well for many investors. 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. 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 us.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 | 10/31/11 3 Portfolio Management Discussion | 10/31/11 Against a fast-changing backdrop for fixed-income investing, high-yield corporate bonds and other credit-sensitive securities produced modestly positive results over the 12 months ended October 31, 2011. The credit-sensitive sectors performed well early in the 12-month period amid general confidence and a broad global recovery, but markets grew increasingly volatile in the latter part of the period as a variety of concerns weighed on investors' minds. In the following interview, Andrew Feltus discusses the factors that influenced the performance of Pioneer Global High Yield Fund during the 12 months ended October 31, 2011. Mr. Feltus, senior vice president and portfolio manager at Pioneer, and Tracy Wright, senior vice president and portfolio manager at Pioneer, are responsible for the daily management of the Fund. Q How did the Fund perform during the 12 months ending October 31, 2011? A Pioneer Global High Yield Fund Class A shares returned 0.49% at net asset value over the 12 months ended October 31, 2011, while the Fund's benchmarks, the Bank of America (BofA) Merrill Lynch (ML) High Yield Master II Index and the BofA ML Global High Yield and Emerging Markets Plus Index, returned 4.81% and 3.34%, respectively. Over the same 12-month period, the average return of the 495 mutual funds in Lipper's High Current Yield Funds category was 3.60%. On October 31, 2011, the 30-day standardized SEC yield of the Fund's Class A shares was 9.41% with fees waived and 9.33% without fees waived. Q What were the principal factors that affected the Fund's benchmark- relative performance during the 12 months ended October 31, 2011? A The major factor behind the Fund's underperformance relative to both BofA ML benchmarks -- particularly the Global High Yield and Emerging Markets Plus Index -- as well as the Fund's Lipper peer group average, was greater portfolio exposure to higher-yielding investments. While the benchmark indices had as much as 22% of assets allocated to investment-grade debt, we generally retained a greater emphasis on lower-rated, high-yielding debt in the Fund's portfolio. For example, at the end of the period on October 31, 2011, just 7.1% of the Fund's net assets were allocated to securities with investment-grade credit ratings of BBB or higher. Moreover, the Fund's exposure to corporate high-yield bonds in the emerging markets held back results relative to the BofA ML High Yield Master II Index, which is primarily a domestic-oriented benchmark. 4 Pioneer Global High Yield Fund | Annual Report | 10/31/11 While a variety of factors combined to drive high-yield prices down in the final half of the Fund's fiscal year, we believe that the bond market overreacted and that high-yield debt has become significantly undervalued as a result. The yield spreads between domestic high-yield corporates and Treasuries had widened to approximately 7.5%, or 750 basis points (bps) by October 31, 2011. (Yield spreads are defined as the difference in yield between Treasuries and lower-quality securities.) By historical standards, that type of yield spread reflects a default rate of approximately 9%, and yet the current default rate (as of October 31, 2011) for high-yield securities is just 2%. We also think corporations are in solid financial shape, with strong balance sheets -- much stronger, in fact, than we saw going into the recession of 2007-2008 -- and we do not expect any significant rise in default rates at a time when U.S. corporations generally have been improving their earnings. The low prices for high-yield bonds are not, in our estimation, justified by the underlying economic fundamentals. Q What was the high-yield market environment like during the 12 months ended October 31, 2011? A The first six months of the period actually offered a favorable environment for high-yield investing. Investors were generally confident that the global economic recovery would continue and strengthen. At the same time, the U.S. Federal Reserve's (the Fed's) stimulative monetary policy had injected more liquidity into the market and encouraged investment. The first cracks in the positive picture began appearing in April 2011, when the Fed's sale of some asset-backed securities led to lower prices for the credit sectors in general. Not too much later, sovereign-debt problems in Greece, Italy and several other European countries started dominating the news, raising worries among investors that European debt problems could have contagious effects on the global economy. Investor confidence was undermined further during the summer months by new data indicating that unemployment problems in the U.S. were not improving and that economic growth was weakening. The growth of gross domestic product (GDP) in the U.S. moved at a modest 1.3% annual pace for the second quarter of 2011 (April through June). To make matters worse, confidence in the ability of the federal government to make decisions faltered. The debate in Washington, D.C., over raising the national debt ceiling further undermined investor confidence, which received an additional jolt in early August when the Standard & Poor's credit rating agency issued its first-ever ratings downgrade for U.S. Treasury securities. The market for higher-yielding, emerging market debt also fared badly over the final six months of the Fund's fiscal year, with investment money flowing out of the emerging markets over the final two months as investors sought perceived safer havens during a time of market volatility. Pioneer Global High Yield Fund | Annual Report | 10/31/11 5 After the almost unrelenting tide of negative news, the market appeared to start turning around again in the final weeks of the 12-month period. First, new data about the domestic economy appeared to show some unexpected strength, and even the jobs market showed evidence of improvement. At the same time, European political and financial leaders appeared to be seriously addressing the major debt problems affecting some European nations. In reaction, the domestic high-yield market rallied again in the final month of the Fund's fiscal year. Q How did the Fund's positioning and security selection affect its performance over the 12 months ended October 31, 2011? A As we indicated previously, the heavy emphasis on high-yield debt in the portfolio -- predominately U.S. corporate bonds -- was the major factor behind the Fund's somewhat disappointing results, particularly when compared with the BofA ML benchmarks and the Lipper peer group. Also, as we noted previously, the Fund's investments in high-yielding corporate debt in the emerging markets hurt performance relative to the BofA ML High Yield Master II Index. Approximately 90% of the Fund's emerging market investments were in corporate bonds. Investments in floating-rate bank loans also did not help performance, as the group sold off aggressively during the market downturn in August. The biggest performance detractor from an individual security standpoint was the Fund's investment in the debt of Sino Forest, a Canadian corporation operating in China. The bonds fell sharply in value when the company faced accusations of fraud. Nevertheless, the company continued to make payments on its bonds during the controversy. Also holding back Fund results were investments in two China-based solar energy companies, Suntech Power and ReneSola. Another investment that did not help the Fund's performance was the debt of Sevan Marine, which manufactures offshore drilling platforms for the energy industry. The company restructured its debt when it ran into cash-flow problems. On the positive side, our decision to underweight the Fund in Europe tended to help relative performance, as European high-yield bonds performed worse than domestic bonds, especially in the final six months of the Fund's fiscal year when the declining value of European bonds was exacerbated by poor performance by the euro currency. Another plus came from the Fund's investments in catastrophe-linked bonds (also known as event-linked bonds), which are securities issued by property-and-casualty reinsurance companies to spread out the risks associated with property claims from large natural disasters. Although the group underperformed immediately following the March 2011 earthquake and tsunami in Japan, it held up better later in the Fund's fiscal year. 6 Pioneer Global High Yield Fund | Annual Report | 10/31/11 Individual investments that helped the Fund's performance included convertible securities of Cubist Pharmaceuticals, a biotechnology firm specializing in antibiotics, and WESCO International, a distributor of electronic industrial components. In addition, the Fund profited from the appreciation in value of the bonds of two companies, Vangent and Global Crossing, that were acquired by larger corporations. As of October 31, 2011, roughly 60% of the Fund's net assets were invested in U.S. high-yield securities, mainly corporates; about 28% of assets were invested in emerging market securities, also primarily in corporates; while the other 12% of the Fund's assets were divided among floating-rate bank loans, international high-yield securities (outside of the emerging markets), and cash/cash equivalents. Q What is your investment outlook? A We continue to be optimistic, as we believe that the U.S. and global economies should expand, although at moderate paces. U.S. high-yield debt appears to be undervalued. We do not expect defaults in the high-yield sector to rise noticeably and we anticipate continuing to emphasize that group in the Fund's portfolio. The two principal risks facing the market appear to be from outside the U.S. Worries about sovereign-debt problems in Europe will likely keep markets around the world volatile. At the same time, investors are concerned that the Chinese government will become more aggressive in slowing the rate of domestic growth in that country, and that could have a damaging effect on the global economy. Despite the risks, we think high-yield bonds offer potentially attractive opportunities, particularly during a time when economies are growing and corporations appear to have healthy finances.

Pioneer Global High Yield Fund | Annual Report | 10/31/11 7 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 issuers 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. 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 High Yield Fund | Annual Report | 10/31/11 15 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 May 1, 2011 through October 31, 2011. ----------------------------------------------------------------------------------------------------- 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 5/1/11 ----------------------------------------------------------------------------------------------------- Ending Account Value $932.88 $929.07 $930.15 $934.58 $931.44 (after expenses) on 10/31/11 ----------------------------------------------------------------------------------------------------- Expenses Paid $5.31 $9.24 $8.66 $3.61 $3.70 During Period* ----------------------------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.09%, 1.90%, 1.78%, 0.74%, and 0.76%, 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 184/365 (to reflect the one-half year period). 16 Pioneer Global High Yield Fund | Annual Report | 10/31/11 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 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 as of the close of business on 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. 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. 66 Pioneer Global High Yield Fund | Annual Report | 10/31/11 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, an independent pricing service. 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. 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. 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. 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. 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. Securities or senior 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. 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. Examples of a significant event might include political or economic news, corporate restructurings, natural disasters, terrorist activity or trading halts. Thus, the valuation of the Fund's securities may differ from exchange prices. Pioneer Global High Yield Fund | Annual Report | 10/31/11 67 At October 31, 2011, five securities were valued using fair value methods (in addition to securities valued using prices supplied by independent pricing services) representing 0.31% 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. 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. 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 68 Pioneer Global High Yield Fund | Annual Report | 10/31/11 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 9). 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 federal and state 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, 2011, the Fund had a net capital loss carryforward of $235,848,362 of which the following amounts will expire between 2016 and 2018, if not utilized: $4,718,467 in 2016, $204,858,985 in 2017 and $26,270,910 in 2018. At October 31, 2011, the Fund reclassified $22,338 to decrease paid-in capital, $10,823,509 to decrease distributions in excess of net investment income and $10,801,171 to increase accumulated net realized loss, 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. Under the recently enacted Regulated Investment Company Modernization Act of 2010, the Fund will be permitted to carry forward capital losses incurred in taxable years beginning after December 22, 2010 for an unlimited period. However, any losses incurred during those future years will be required to be utilized prior to the losses incurred in pre-enactment tax years. As a result of this ordering rule, pre-enactment capital loss carryforwards may be more likely to expire unused. Additionally, post-enactment capital losses that are carried forward will retain their character as either short-term or long-term capital losses rather than being considered all short-term as under previous law. The tax character of distributions paid during the years ended October 31, 2011 and October 31, 2010 was as follows: Pioneer Global High Yield Fund | Annual Report | 10/31/11 69 --------------------------------------------------------------------------- 2011 2010 --------------------------------------------------------------------------- Distributions paid from: Ordinary income $204,322,757 $163,595,781 --------------------------------------------------------------------------- Total $204,322,757 $163,595,781 =========================================================================== The following shows the components of distributable earnings on a federal income tax basis at October 31, 2011: --------------------------------------------------------------------------- 2011 --------------------------------------------------------------------------- Distributable earnings: Undistributed ordinary income $ 15,829,962 Capital loss carryforward (235,848,362) Dividends payable (2,135,872) Net unrealized loss (171,119,102) --------------------------------------------------------------------------- Total $ (393,273,374) =========================================================================== The difference between book-basis and tax-basis net unrealized loss is attributable to the tax deferral of losses on wash sales, the mark-to-market of foreign currency contracts, adjustments relating to catastrophe bonds, credit default swaps, interest accruals on preferred stocks 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 $164,670 in underwriting commissions on the sale of Class A shares during the year ended October 31, 2011. 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. During the year ended October 31, 2011, the Fund recognized gains of $385,359 in the settlement of class action lawsuits from several different companies, as reflected on the Statement of Operations. 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 5). Class Y and Class Z 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 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). 70 Pioneer Global High Yield Fund | Annual Report | 10/31/11 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. Risks 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 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. H. 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. I. 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 Pioneer Global High Yield Fund | Annual Report | 10/31/11 71 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. J. 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 portfolio or to hedge the risk of default on portfolio securities. As a seller of protection, the Fund would be required to pay the notional (or other agreed-upon) value of the referenced debt obligation to the counterparty in the event of a default by a U.S. or foreign corporate issuer of a debt obligation, which would likely result in a loss to the Fund. In return, the Fund would receive from the counterparty a periodic stream of payments during the term of the contract provided that no event of default occurred. The maximum exposure of loss to the seller would be the notional value of the credit default swaps outstanding. If no default occurs, the Fund would keep the stream of payments and would have no payment obligation. The Fund may also buy credit default swap contracts in order to hedge against the risk of default of debt securities, in which case the Fund would function as the counterparty referenced above. 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. 72 Pioneer Global High Yield Fund | Annual Report | 10/31/11 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. During the year ended October 31, 2011, the Fund opened one credit default swap, with a notional amount of $14,000,000, which was still open at year end. Credit default swap contracts outstanding at year end are listed at the end of the Fund's schedule of investments. 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, 2011, the effective management fee (excluding waivers and/or assumption of expenses) was equivalent to 0.58% 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 $127,335 in management fees, administrative costs and certain other reimbursements payable to PIM at October 31, 2011. Pioneer Global High Yield Fund | Annual Report | 10/31/11 73 3.

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. 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, 2011, the average daily amount of borrowings outstanding during the period was $37,930,560.

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, 2011, 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 consolidated 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, 2011, the consolidated results of its operations, the consolidated changes in its net assets, and the consolidated financial highlights for the year then ended, and the changes in net assets for the year ended October 31, 2011 and the financial highlights for each of the periods ended October 31, 2011, in conformity with U.S. generally accepted accounting principles. /s/ Ernst & Young LLP Boston, Massachusetts December 23, 2011 78 Pioneer Global High Yield Fund | Annual Report | 10/31/11 ADDITIONAL INFORMATION (unaudited) The percentage of the Fund's ordinary income distributions that are exempt from nonresident alien (NRA) tax withholding resulting from qualified interest income was 55.65%.

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.
