All year, investors focused on the Federal Reserve System's (the Fed's) deliberations over when to begin normalizing interest rates. However, while there were signs of gradual economic improvement in the U.S., economies abroad increasingly diverged. In June, for example, investors grew concerned about the debt crisis in Greece. That news, in turn, was followed by evidence of an economic slowdown in China, which only served to exacerbate existing worries about growth trends in the emerging markets, a segment of the global economy already being negatively impacted by slumping commodity prices, including the price of crude oil, which has been in near-steady decline for almost a year. Through September 30, 2015, the pockets of heightened market volatility alluded to above had resulted in the Standard & Poor's 500 Index turning in a negative (-5.27%) return over the first nine months of the year. However, the S&P 500 recovered nicely in October, returning 8.43% for the month, which boosted the index's year-to-date return into positive territory, at 2.71%. Despite the headwinds still vexing the global economy, our longer-term view of the U.S. economy has remained positive. Economic conditions in the U.S. have generally been constructive, based largely on improvements in employment statistics and an uptick in the housing sector, which has aided the consumer side of the economy, where household spending has been rising modestly. U.S. consumers also stand to benefit, potentially, from lower energy prices as the winter weather approaches. We continue to believe the U.S. economy remains on a slow, steady growth trend, and that it is unlikely to be disrupted by a slow pace of interest-rate normalization by the Fed. Pioneer Investments believes that investors in today's environment can potentially benefit from the consistent and disciplined investment approach we have used since our founding in 1928. We focus on identifying value across global markets using proprietary research, careful risk management, and a long-term perspective. Our ongoing goal is to produce compelling returns consistent with the stated objectives of our investment products, and with our shareowners' expectations. We believe our shareowners can benefit from the experience and tenure of our investment teams as well as the insights generated from our extensive research process. 2 Pioneer Global High Yield Fund | Annual Report | 10/31/15 As always, and particularly during times of market uncertainty, we encourage you to work with your financial advisor to develop an overall investment plan that addresses both your short- and long-term goals, and to implement such a plan in a disciplined manner. We greatly appreciate your trust in us in the past and look forward to continuing to serve you in the future. Sincerely, /s/ Lisa M. Jones Lisa M.

Pioneer Global High Yield Fund | Annual Report | 10/31/15 3 Portfolio Management Discussion | 10/31/15 Credit-sensitive securities, including high-yield corporate bonds and emerging markets debt, struggled over most of the 12-month period ended October 31, 2015, as investors' concerns about the declining prices of oil and other commodities, and mounting fears of global economic weakening, negatively affected the markets. In the following interview, Andrew Feltus and Tracy Wright discuss the market environment and the performance of Pioneer Global High Yield Fund during the 12-month period. Mr. Feltus, Director of High Yield and Bank Loans, a senior vice president and a portfolio manager at Pioneer, is lead manager of the Fund, and Ms. Wright, a senior vice president and portfolio manager at Pioneer, is the co-manager of the Fund. Together, they are responsible for the day-to-day management of the Fund. Q How did the Fund perform during the 12-month period ended October 31, 2015? A Pioneer Global High Yield Fund's Class A shares returned -6.36% at net asset value during the 12-month period ended October 31, 2015, while the Fund's benchmarks, the Barclays Global High Yield Index (the Barclays Index) and the Bank of America Merrill Lynch (BofA ML) High Yield Master II Index, each returned -2.05%. During the same period, the average return of the 656 mutual funds in Lipper's High Yield Funds category was -2.24%, and the average return of the 773 mutual funds in Morningstar's High Yield Bond Funds category was -2.09%. Q How would you describe the investment environment in the global high-yield markets during the 12-month period ended October 31, 2015? A Declining commodity prices - especially of crude oil - and concerns about global economic growth trends dragged down the high-yield bond market over the 12-month period. The domestic high-yield corporate bond market, with its large exposures to debt issued by energy firms as well as by metals and mining companies, was hit particularly hard. Emerging markets securities also sold off significantly, as many emerging economies are heavily dependent on exports of oil and other commodities. European high-yield bonds, however, were less exposed to commodity prices and tended to hold up somewhat better (in local currency values), especially in light of the European Central Bank's (ECB's) easing of monetary policy during the period; however, the weakness of the euro in world currency markets had a negative impact on European high-yield's performance on an unhedged basis. At the start of the 12-month period, during the fourth quarter of 2014, declining oil prices tended to pull down both the emerging and domestic high-yield markets, as both had relatively large exposures to oil-related 4 Pioneer Global High Yield Fund | Annual Report | 10/31/15 industries. In fact, bonds issued by energy companies accounted for between roughly 12% to 16% of domestic high-yield corporate bonds, and as much as 40% of emerging markets corporate debt. Early in 2015, energy-related bonds tended to show some improvement as oil prices firmed, but oil began declining again at mid-year and the price of crude continued to drop all the way through the end of the period. This, once again, had a negative effect on both domestic high-yield bonds and emerging markets debt. At the same time, evidence of slowing economic growth trends in China raised still more concerns, this time about possible contagion effects a slowdown in China may have on many emerging markets economies, and on the global economic growth outlook in general. Adding to the negative factors affecting the high-yield markets were growing expectations that the U.S. Federal Reserve System (the Fed), sooner rather than later, would begin raising short-term interest rates for the first time in nearly a decade. While emerging markets bonds struggled overall during the 12-month period, a credit-rating downgrade on Russian debt resulted in the addition of those securities to emerging markets benchmarks, which turned out to be a positive development. After the downgrade, Russian debt instruments - both sovereigns and corporates - rallied and lent support to some market indices. In the final month of the period, the domestic high-yield market did stage a rally, with one of the Fund's benchmarks, the BofA ML High Yield Master II Index, rising by 2.73% for the month after the Fed announced in September that it would again delay any move to increase short-term interest rates. Q Which factors had the biggest effects on the Fund's performance relative to the high-yield benchmarks during the 12-month period ended October 31, 2015? A The Fund's benchmark-relative underperformance during the period was due primarily to overall security selection results. In particular, security selection results in the energy sector and among the portfolio's emerging markets debt holdings acted as major drags on relative returns. The negative effects of adverse security selection offset the positive impact of our heavy emphasis on the U.S. dollar in the portfolio, as the dollar appreciated in value versus most foreign currencies during the period. In addition, the Fund's non-benchmark exposures to floating-rate bank loans and insurance-linked securities contributed to benchmark-relative results. With regard to individual positions, several of the Fund's investments in emerging markets debt detracted significantly from relative performance. Notably, a position in OAS, a Brazilian construction company that filed for bankruptcy protection in January 2015, hurt relative returns. The effects of the OAS bankruptcy filing spread and undermined the performance of bonds of other construction companies located in the emerging markets, Pioneer Global High Yield Fund | Annual Report | 10/31/15 5 including ICA, a Mexican company whose bonds the portfolio also owned. In addition, the Fund's investment in the debt of Pacific Rubicales Energy, a Colombia-based corporation, was a detractor from relative performance as the bonds sold off after shareholders blocked the planned sale of the corporation to a Mexican firm. On the positive side, the portfolio did have several positions in the domestic high-yield market that supported the Fund's benchmark-relative results during the period, including the bonds of Lantheus Medical, a corporation which provides diagnostic medical imaging services that was able to refinance its debt after an initial public stock offering. In the emerging markets, a number of the Fund's Argentina-based holdings performed well on investors' expectations of government reforms in the country. Some of the stronger performers in the Fund's portfolio during the period were securities issued by IRSA, an Argentinian real estate company, and Banco Galicia, a financial services company. Q Did the Fund invest in any derivative securities during the 12-month period ended October 31, 2015? If so, what impact did those investments have on benchmark-relative results? A Yes, we did invest the Fund in some forward currency contracts as part of our strategy to overweight the portfolio to the U.S. dollar. The use of these contracts had a positive effect on the Fund's results as the dollar strengthened against most foreign currencies. Q What factors affected the Fund's dividend* during the 12-month period ended October 31, 2015? A The Fund's dividend was reduced in late 2014, but it has remained stable during the first 10 months of 2015. During the full 12-month period, yield spreads (or yield differences) between higher-rated and lower-rated bonds have widened, and high-yield bonds have underperformed. We think this development may afford us the potential to reinvest the Fund's assets in securities with higher coupon rates in the future, even though we are still in a low-interest-rate environment. * Dividends are not guaranteed. 6 Pioneer Global High Yield Fund | Annual Report | 10/31/15 Q What is your investment outlook? A As the Fund enters a new fiscal year, a major factor influencing the prospects for high-yield securities is how soon the Fed tightens monetary policy by raising short-term interest rates. The Fed's decision in 2014 to end its monthly quantitative easing bond purchases contributed to the volatility in the high-yield bond market, and we believe raising short-term rates may have a similar effect. Overall, we have a positive outlook for high-yield securities. At current prices, we think domestic high-yield bonds offer real value, especially after the volatility of the past year, which has increased the relative attractiveness of the asset class. Yield spreads have widened substantially and are more than compensating investors for default risk, which remains well below the historic 4% long-term average for the high-yield market; we think even spread levels on energy-related corporate bonds more than compensate investors for current risk factors. Corporate issuers, meanwhile, have generally maintained solid profit margins and healthy balance sheets, and continue to have good access to capital. Additionally, the high levels of leveraged buyout activity seen in the recent past have receded, which should be a positive factor for the bond market going forward. Finally, we think the prospects for emerging markets debt, and for domestic energy as well as mining and metals bond issuers can only improve if there is strengthening in the prices of oil and other commodities. Pioneer Global High Yield Fund | Annual Report | 10/31/15 7 Please refer to the Schedule of Investments on pages 16-43 for a full listing of Fund securities. Investments in high-yield or lower-rated securities are subject to greater-than- average price volatility, illiquidity and possibility of default. 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 issuers of underlying securities and their inability to meet their debt obligations. Investing in foreign and/or emerging markets securities involves risks relating to interest rates, currency exchange rates, and economic and political conditions. Prepayment risk is the chance that an issuer may exercise its right to repay its security, if falling interest rates prompt the issuer to do so. 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. The Fund 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 Fund may use derivatives, such as options, futures, inverse floating rate obligations, swaps, and others, which can be illiquid, may disproportionately increase losses, and have a potentially large impact on Fund performance. Derivatives may have a leveraging effect on the Fund. 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. Before investing, consider the product's investment objectives, risks, charges and expenses.

Class Y shares are not subject to sales charges and are available for limited groups of eligible investors, including institutional investors. All results are historical and assume the reinvestment of dividends and capital gains. Other share classes are available for which performance and expenses will differ. Performance results reflect any applicable expense waivers in effect during the periods shown. Without such waivers Fund performance would be lower. Waivers may not be in effect for all funds. Certain fee waivers are contractual through a specified period. Otherwise, fee waivers can be rescinded at any time. See the prospectus and financial statements for more information. The performance table and graph do not reflect the deduction of fees and taxes that a shareowner would pay on Fund distributions or the redemption of Fund shares. Pioneer Global High Yield Fund | Annual Report | 10/31/15 13 Comparing Ongoing Fund Expenses As a shareowner in the Fund, you incur two types of costs: (1) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses; and (2) transaction costs, including sales charges (loads) on purchase payments. This example is intended to help you understand your ongoing expenses (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 at the beginning of the Fund's latest six-month period and held throughout the six months. Using the Tables -------------------------------------------------------------------------------- Actual Expenses The first table below provides information about actual account values and actual expenses. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period as follows: (1) Divide your account value by $1,000 Example: an $8,600 account value (divided by) $1,000 = 8.6 (2) Multiply the result in (1) above by the corresponding share class's number in the third row under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Expenses Paid on a $1,000 Investment in Pioneer Global High Yield Fund Based on actual returns from May 1, 2015, through October 31, 2015. -------------------------------------------------------------------------------- Share Class A C Y -------------------------------------------------------------------------------- Beginning Account $1,000.00 $1,000.00 $1,000.00 Value on 5/1/15 -------------------------------------------------------------------------------- Ending Account $ 949.21 $ 945.53 $ 950.32 Value (after expenses) on 10/31/15 -------------------------------------------------------------------------------- Expenses Paid $ 5.75 $ 9.17 $ 4.28 During Period* -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized net expense ratio of 1.17%, 1.87%, and 0.87% for Class A, Class C and Class Y shares, respectively, multiplied by the average account value over the period, multiplied by 184/365 (to reflect the one-half year period). 14 Pioneer Global High Yield Fund | Annual Report | 10/31/15 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. Expenses Paid on a $1,000 Investment in Pioneer Global High Yield Fund Based on a hypothetical 5% return per year before expenses, reflecting the period from May 1, 2015, through October 31, 2015. -------------------------------------------------------------------------------- Share Class A C Y -------------------------------------------------------------------------------- Beginning Account $1,000.00 $1,000.00 $1,000.00 Value on 5/1/15 -------------------------------------------------------------------------------- Ending Account $1,019.31 $1,015.78 $1,020.82 Value (after expenses) on 10/31/15 -------------------------------------------------------------------------------- Expenses Paid $ 5.96 $ 9.50 $ 4.43 During Period* -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized net expense ratio of 1.17%, 1.87%, and 0.87% for Class A, Class C and Class Y shares, respectively, multiplied by the average account value over the period, multiplied by 184/365 (to reflect the one-half year period).

Organization and Significant Accounting Policies Pioneer Global High Yield Fund (the Fund) is one of three portfolios comprising Pioneer Series Trust VII (the Trust), 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 three classes of shares designated as Class A, Class C and Class Y shares. Class B shares were converted to Class A shares as of the close of business on November 10, 2014. Class Z shares converted to Class Y shares as of the close of business on August 7, 2015. 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 year. 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: Pioneer Global High Yield Fund | Annual Report | 10/31/15 51 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 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. 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. If price information is not available from Loan Pricing Corporation, or if the price is deemed to be unreliable, price information will be obtained from an alternate loan interest pricing service. If no reliable price quotes are available from either the primary or alternative pricing service, broker quotes will be solicited. Event-linked bonds are valued at the bid price obtained from an independent third party pricing service. Other insurance-linked securities may be valued at the bid price obtained from an independent pricing service, or through a third party using a pricing matrix, insurance industry valuation models, or other fair value methods or techniques to provide an estimated value of the instrument. 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 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. Shares of money market mutual funds are valued at such funds' net asset value. Cash may include overnight time deposits at approved financial institutions. 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. Securities or senior loans for which market prices and/or quotations are not readily available or are considered to be unreliable are valued by a fair valuation team comprised of certain personnel of Pioneer Investment Management, Inc. (PIM), the Fund's investment adviser, pursuant to procedures adopted by the Fund's Board of Trustees. PIM's fair valuation team uses fair value methods approved by the Valuation Committee of the Board of Trustees. PIM's fair value valuation team is responsible for 52 Pioneer Global High Yield Fund | Annual Report | 10/31/15 monitoring developments that may impact fair valued securities and for discussing and assessing fair values on an ongoing basis, and at least quarterly, with the Valuation Committee of the Board of Trustees. 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. The Trust 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 Trust'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 Trust's securities may differ significantly from exchange prices and such differences could be material. At October 31, 2015, ten securities were valued using fair value methods (in addition to securities valued using prices supplied by independent pricing services, broker-dealers or through a third party using an insurance industry valuation model) representing 1.0% of net assets. B. Investment Income and Transactions 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 purchase prices of 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, 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. C. 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. Pioneer Global High Yield Fund | Annual Report | 10/31/15 53 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 the market prices of those securities but are included with the net realized and unrealized gain or loss on investments. D. 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 appreciation or depreciation is recorded in the Fund's financial statements. The Fund records realized gains and losses at the time a hedge is offset by entry into a closing transaction or extinguished by delivery of the currency. Risks may arise upon entering into these contracts from the potential inability of counterparties to meet the terms of the contract and from unanticipated movements in the value of foreign currencies relative to the U.S. dollar (See Note 8). E. 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 net taxable income and net realized capital gains, if any, to its shareowners. Therefore, no provision for federal income taxes is required. As of October 31, 2015, the Fund did not accrue any interest or penalties with respect to uncertain tax positions, which, if applicable, would be recorded as an income tax expense in the Statement of Operations. Tax returns filed within the prior three years remain subject to examination by federal and state tax authorities. The amount and character of income and capital gain distributions to shareowners are determined in accordance with federal income tax rules, which may differ from U.S. generally accepted accounting principles. Distributions in excess of net investment income or net realized gains are temporary overdistributions for financial statement purposes resulting from differences in the recognition or classification of income or distributions for financial statement and tax purposes. Capital accounts within the financial statements are adjusted for permanent book/tax differences to reflect tax character, but are not adjusted for temporary differences. 54 Pioneer Global High Yield Fund | Annual Report | 10/31/15 At October 31, 2015, the Fund reclassified $13,907,516 to increase distributed in excess of net investment income and $13,907,516 to decrease accumulated net realized loss on investments, written options and foreign currency transactions to reflect permanent book/tax differences. These adjustments have no impact on net assets or the results of operations. At October 31, 2015, the Fund was permitted to carry forward indefinitely $14,957,489 of short-term losses and $147,107,113 of long-term losses under the Regulated Investment Company Modernization Act of 2010 without limitation. Additionally, at October 31, 2015, 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. The tax character of distributions paid during the years ended October 31, 2015 and October 31, 2014 were as follows: --------------------------------------------------------------------------- 2015 2014 --------------------------------------------------------------------------- Distributions paid from: Ordinary income $59,414,496 $100,787,602 Return of capital 10,222,285 4,607,391 --------------------------------------------------------------------------- Total $69,736,781 $105,394,993 =========================================================================== The following shows the components of distributable earnings on a federal income tax basis at October 31, 2015: --------------------------------------------------------------------------- 2015 --------------------------------------------------------------------------- Distributable earnings: Capital loss carryforward $(397,912,964) Current year dividend payable (668,299) Net unrealized depreciation (129,935,691) --------------------------------------------------------------------------- Total $(528,516,954) =========================================================================== The difference between book basis and tax basis unrealized depreciation is attributable to the tax deferral of losses on wash sales, the mark-to-market of foreign currency contracts, adjustments relating to catastrophe bonds, partnerships, interest on defaulted bonds, and interest accruals on preferred stock. F. 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 $28,208 in underwriting commissions on the sale of Class A shares during the year ended October 31, 2015. Pioneer Global High Yield Fund | Annual Report | 10/31/15 55 G. 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 Fund's transfer agent 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. H. Insurance Linked Securities (ILS) Event-linked bonds are floating rate debt obligations for which the return of principal and the payment of interest are contingent on the non-occurrence of a pre-defined "trigger" event, such as a hurricane or an earthquake of a specific magnitude. The trigger event's magnitude may be based on losses to a company or industry, industry indexes or readings of scientific instruments, or may be based on specified actual losses. If a trigger event, as defined within the terms of an event-linked bond occurs, the fund may lose a portion or all of its accrued interest and/or principal invested in such event-linked bond. The fund is entitled to receive principal and interest payments so long as no trigger event occurs of the description and magnitude specified by the instrument. In addition to the specified trigger events, event-linked bonds may expose the Fund to other risks, including but not limited to issuer (credit) default, adverse regulatory or jurisdictional interpretations and adverse tax consequences. The Fund's investments in ILS may include special purpose vehicles ("SPVs") or similar instruments structured to comprise a portion of a reinsurer's catastrophe-oriented business, known as quota share instruments (sometimes referred to as reinsurance sidecars), or to provide reinsurance relating to specific risks to insurance or reinsurance companies through a collateralized instrument, known as collateralized reinsurance. Structured reinsurance investments also may include industry loss warranties ("ILWs"), are subject to the same risks as event-linked bonds. In addition, because quota share 56 Pioneer Global High Yield Fund | Annual Report | 10/31/15 instruments represent an interest in a basket of underlying reinsurance contracts, the Fund has limited transparency into the individual underlying contracts and therefore must rely upon the risk assessment and sound underwriting practices of the issuer. Accordingly, it may be more difficult for PIM to fully evaluate the underlying risk profile of the Fund's investment in quota share instruments and therefore place the Fund's assets at greater risk of loss than if PIM had more complete information. Quota share instruments and other structured reinsurance instruments generally will be considered illiquid securities by the Fund. These securities may be difficult to purchase, sell or unwind. Illiquid securities also may be difficult to value. If the Fund is forced to sell an illiquid asset, the Fund may be forced to sell at a loss. I. 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. J. Option Writing The Fund may write put and covered call options to seek to increase total return. When an option is written, the Fund receives a premium and becomes obligated to purchase or sell the underlying security at a fixed price, upon the exercise of the option. When the Fund writes an option, an amount equal to the premium received by the Fund is recorded as a liability and is subsequently adjusted to the current value of the option written. Premiums received from writing options that expire unexercised are treated by the Fund on the expiration date as realized gains from investments. The difference between the premium and the amount paid on effecting a closing purchase transaction, including brokerage commissions, is also treated as a realized Pioneer Global High Yield Fund | Annual Report | 10/31/15 57 gain, or, if the premium is less than the amount paid for the closing purchase transaction, as a realized loss. If a call option is exercised, the premium is added to the proceeds from the sale of the underlying security in determining whether the Fund has realized a gain or loss. The Fund as writer of an option bears the market risk of an unfavorable change in the price of the security underlying the written option. The average value of contracts open during the year ended October 31, 2015 was $(7). There were no written options outstanding at October 31, 2015. Transactions in written options for the year ended October 31, 2015 are summarized as follows: --------------------------------------------------------------------------- Number of Contracts Premium Received --------------------------------------------------------------------------- Options open at beginning of period (4,923,449) $ (81,114) Options opened -- -- Options exercised -- -- Options closed -- -- Options expired 4,923,449 81,114 --------------------------------------------------------------------------- Options open at end of period -- $ -- =========================================================================== 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% on assets over $2 billion. For the year ended October 31, 2015, the effective management fee (excluding waivers and/or assumption of expenses) was equivalent to 0.66% of the Fund's average daily net assets. In addition, under the management and administration agreements, certain other services and costs, including accounting, regulatory reporting and insurance premiums, are paid by the Fund as administrative reimbursements.

Line of Credit Facility The Fund, along with certain other funds in the Pioneer Family of Funds (the Funds), participates in a 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. The credit facility in effect until June 9, 2015 is in the amount of $215 million. As of June 9, 2015, the facility was in the amount of $240 million. Under such facility, depending on the type of loan, interest on borrowings is payable at the London Interbank Offered Rate (LIBOR) plus 0.85% on an annualized basis, or the alternate base rate, which is the greater of (a) the facility's administrative agent's daily announced prime rate on the borrowing date, (b) 2% plus the federal funds rate on the borrowing date and (c) 2% plus the overnight eurodollar rate on the borrowing date. The Funds pay an annual commitment fee to participate in the credit 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, 2015, the Fund had no borrowings under the credit facility. 6. Expense Offset Arrangements The Fund entered into certain expense offset arrangements with PIMSS which may result in a reduction in the Fund's total expenses due to interest earned on cash held by PIMSS. For the year ended October 31, 2015, the Fund's expenses were not reduced under such arrangements. 7. Bridge Loan Commitments Bridge loans are designed to provide temporary or "bridge" financing to a borrower pending the sale of identified assets or the arrangement of longer term loans or the issuance or sale of debt obligations. As of October 31, 2015, the Fund had one bridge loan commitment of $5,007,826, which could be extended at the option of the borrower, pursuant to the following loan agreement: -------------------------------------------------------------------------------- Unrealized Appreciation/ Loan Shares Cost Value Depreciation -------------------------------------------------------------------------------- Charter Communications Operating Co., Bridge Loan 5,007,826 $5,007,826 $5,007,826 $ -- -------------------------------------------------------------------------------- Total 5,007,826 $5,007,826 $5,007,826 $ -- ================================================================================ 8. Forward Foreign Currency Contracts At October 31, 2015, the Fund had entered into various forward foreign currency contracts that obligate the Fund to deliver or take delivery of currencies at specified future maturity dates. Alternatively, prior to the 60 Pioneer Global High Yield Fund | Annual Report | 10/31/15 settlement date of a forward foreign currency contract, the Fund may close out such contract by entering into an offsetting contract. The average value of contracts open during the year ended October 31, 2015 was $(13,016,519). Open forward foreign currency contracts at October 31, 2015 were as follows: -------------------------------------------------------------------------------------------------------- Currency Currency In Exchange Settlement Unrealized Sold Deliver Purchased for Counterparty Date Appreciation -------------------------------------------------------------------------------------------------------- EUR (Euro) (7,397,123) USD 8,321,280 JP Morgan Chase Bank 12/4/15 $ 176,400 EUR (Euro) (5,234,016) USD 5,941,196 Societe Generale 12/4/15 178,086 JPY (Yen Japan) (667,733,813) USD 5,570,483 Brown Brothers Harriman And Co. 11/25/15 37,011 EUR (Euro) (1,045,826) USD 1,196,098 Citibank N.A. 12/4/15 44,552 -------------------------------------------------------------------------------------------------------- Total $ 436,049 ======================================================================================================== -------------------------------------------------------------------------------------------------------- Currency Currency In Exchange Settlement Unrealized Sold Deliver Purchased for Counterparty Date Depreciation -------------------------------------------------------------------------------------------------------- GBP (British Pound Sterling) (2,928,331) USD 4,483,554 Citibank N.A. 11/3/15 $ (34,423) MXN (Mexican Brown Brothers Peso) (113,070,000) USD 6,737,335 Harriman And Co. 11/23/15 (103,626) RUB (Russian JP Morgan Ruble) (74,085,000) USD 1,136,151 Chase Bank 11/6/15 (23,045) USD (1,738,596) EUR (Euro) 1,565,000 UBS AG 12/4/15 (15,394) GBP (British Pound Brown Brothers Sterling) (2,920,647) USD 4,502,265 Harriman And Co. 12/29/15 (2,897) -------------------------------------------------------------------------------------------------------- Total $ (179,385) ======================================================================================================== 9. Assets and Liabilities Offsetting The Fund has entered into an International Swaps and Derivatives Association, Inc. Master Agreement ("ISDA Master Agreement") or similar agreement with substantially all its derivative counterparties. An ISDA Master Agreement is a bilateral agreement between the Fund and a counterparty that governs the trading of certain OTC derivatives and typically contains, among other things, close-out and set-off provisions which apply upon the occurrence of event of a default and/or termination event as defined under the relevant ISDA Master Agreement. The ISDA Master Agreement may also give a party the right to terminate all transactions traded under such agreement if, among other things, there is deterioration in the credit quality of the other party. Upon an event of default or a termination of the ISDA Master Agreement, the non-defaulting party has the right to close out all transactions under such agreement and to net amounts owed under each transaction to determine one net amount payable by one party to the other. The right to close out and net payments across all transactions under the ISDA Master Agreement could result in a reduction of the Fund's credit risk to its counterparty equal to any amounts payable by the Fund under the applicable transactions, if any. However, the Pioneer Global High Yield Fund | Annual Report | 10/31/15 61 Fund's right to setoff may be restricted or prohibited by the bankruptcy or insolvency laws of the particular jurisdiction to which a specific ISDA counterparty is subject. The collateral requirements for derivatives transactions under an ISDA Master Agreement are governed by a credit support annex to the ISDA Master Agreement. Collateral requirements are generally determined at the close of business each day and are typically based on changes in market values for each transaction under an ISDA Master Agreement and netted into one amount for such agreement. Generally, the amount of collateral due from or to a counterparty is subject to threshold (a "minimum transfer amount") before a transfer is required, which may vary by counterparty. Collateral pledged for the benefit of the Fund and/or counterparty is held in segregated accounts by the Fund's custodian and cannot be sold, re-pledged, assigned or otherwise used while pledged. Cash that has been segregated to cover the Fund's collateral obligations, if any, will be reported separately in the Statement of Assets and Liabilities as "Futures collateral", "Swap Collateral" or "Deposit with broker." Securities pledged by the Fund as collateral, if any, are identified as such in the Schedule of Investments. Financial instruments subject to an enforceable master netting agreement such as an ISDA Master Agreement have been offset on the Statement of Assets and Liabilities. The following charts show gross assets and liabilities of the Fund as of October 31, 2015. -------------------------------------------------------------------------------------------------------- Derivative Assets Derivatives Non-Cash Cash Net Amount Subject to Master Available for Collateral Collateral of Derivative Counterparty Netting Agreement Offset Received (a) Received (a) Assets (b) -------------------------------------------------------------------------------------------------------- JP Morgan Chase Bank $176,400 $ (23,045) $-- $-- $153,355 Societe Generale SA 178,086 -- -- -- 178,086 Citibank N.A. 44,552 (34,423) -- -- 10,129 Brown Brothers Harriman and Co. 37,011 (37,011) -- -- -- UBS AG -- -- -- -- -- -------------------------------------------------------------------------------------------------------- Total $436,049 $ (94,479) $-- $-- $341,570 ======================================================================================================== -------------------------------------------------------------------------------------------------------- Derivative Liabilities Derivatives Non-Cash Cash Net Amount Subject to Master Available for Collateral Collateral of Derivative Counterparty Netting Agreement Offset Pledged (a) Pledged (a) Liabilities (c) -------------------------------------------------------------------------------------------------------- JP Morgan Chase Bank $ 23,045 $ (23,045) $-- $-- $ -- Societe Generale SA -- -- -- -- -- Citibank N.A. 34,423 (34,423) -- -- -- Brown Brothers Harriman and Co. 106,523 (37,011) -- -- 69,512 UBS AG 15,394 -- -- -- 15,394 -------------------------------------------------------------------------------------------------------- Total $179,385 $ (94,479) $-- $-- $ 84,906 ======================================================================================================== 62 Pioneer Global High Yield Fund | Annual Report | 10/31/15 (a) The amount presented here may be less than the total amount of collateral received/pledged as the net amount of derivative assets and liabilities cannot be less than $0.

Additional Disclosures about Derivative Instruments and Hedging Activities: The Fund's use of derivatives subjects it to the following risks: Interest rate risk relates to the fluctuations in the value of interest-bearing securities due to changes in the prevailing levels of market interest rates. Credit risk relates to the ability of the issuer of a financial instrument to make further principal or interest payments on an obligation or commitment that it has to the Fund. Foreign exchange rate risk relates to fluctuations in the value of an asset or liability due to changes in currency exchange rates. Equity risk relates to the fluctuations in the value of financial instruments as a result of changes in market prices (other than those arising from interest rate risk or foreign exchange risk), whether caused by factors specific to an individual investment, its issuer, or all factors affecting all instruments traded in a market or market segment. Commodity risk relates to the risk that the value of a commodity or commodity index will fluctuate based on increases or decreases in the commodities market and factors specific to a particular industry or commodity. The fair value of open derivative instruments (not considered to be hedging instruments for accounting disclosure purposes) by risk exposure at October 31, 2015 was as follows: -------------------------------------------------------------------------------- Foreign Statement of Assets Interest Credit Exchange Equity Commodity and Liabilities Rate Risk Risk Rate Risk Risk Risk -------------------------------------------------------------------------------- Assets Unrealized appreciation of forward foreign currency contracts $-- $-- $ 436,049 $-- $-- -------------------------------------------------------------------------------- Total Value $-- $-- $ 436,049 $-- $-- ================================================================================ Liabilities Unrealized depreciation of forward foreign currency contracts $-- $-- $(179,385) $-- $-- -------------------------------------------------------------------------------- Total Value $-- $-- $(179,385) $-- $-- ================================================================================ Pioneer Global High Yield Fund | Annual Report | 10/31/15 63 The effect of derivative instruments (not considered to be hedging instruments for accounting disclosure purposes) on the Statement of Operations by risk exposure at October 31, 2015 was as follows: -------------------------------------------------------------------------------- Foreign Statement of Interest Credit Exchange Equity Commodity Operations Rate Risk Risk Rate Risk Risk Risk -------------------------------------------------------------------------------- Net realized gain (loss) on Written options $-- $-- $ 81,114 $ -- $-- Forward foreign currency contracts -- -- (748,804) -- -- -------------------------------------------------------------------------------- Total Value $-- $-- $ (667,690) $ -- $-- ================================================================================ Change in net unrealized appreciation (depreciation) on Written options $-- $-- $ (81,027) $ -- $-- Forward foreign currency contracts -- -- (511,304) -- -- -------------------------------------------------------------------------------- Total Value $-- $-- $ (592,331) $ -- $-- ================================================================================ 11. Conversion of Class B and Class Z shares As of the close of business on November 10, 2014, all outstanding Class B shares of the Pioneer funds were converted to Class A shares. As of the close of business on August 7, 2015, all outstanding Class Z shares of the Pioneer funds were converted to Class Y shares. 64 Pioneer Global High Yield Fund | Annual Report | 10/31/15 Report of Independent Registered Public Accounting Firm To the Board of Trustees of Pioneer Series Trust VII and Shareowners of Pioneer Global High Yield Fund: -------------------------------------------------------------------------------- We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Pioneer Global High Yield Fund (one of the portfolios constituting Pioneer Series Trust VII), as of October 31, 2015, and the related statement of operations for the year then ended and the statements of changes in net assets and the financial highlights for each of the two years in the period then ended. 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. The financial highlights for the years ended October 31, 2013, 2012, and 2011 were audited by other auditors. Those auditors expressed an unqualified opinion on those financial statements and financial highlights in their report dated December 23, 2013. 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. The Fund is not required to have, nor were we engaged to perform, an audit of its 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, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of October 31, 2015, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. 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 as of October 31, 2015, the results of its operations for the year then ended, and the changes in its net assets and the financial highlights for each of the two years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. /s/ Deloitte & Touche LLP Boston, Massachusetts December 23, 2015 Pioneer Global High Yield Fund | Annual Report | 10/31/15 65 Additional Information (unaudited) Pioneer Investment Management, Inc. (the "Adviser"), each fund's investment adviser, is currently an indirect, wholly owned subsidiary of UniCredit S.p.A. ("UniCredit"). On November 11, 2015, UniCredit announced that it signed a binding master agreement with Banco Santander and affiliates of Warburg Pincus and General Atlantic (the "Private Equity Firms") with respect to Pioneer Investments ("Pioneer") and Santander Asset Management ("SAM") (the "Transaction"). The Transaction, as previously announced by UniCredit, will establish a holding company, with the name Pioneer Investments, to be owned by UniCredit (50%) and the Private Equity Firms (50% between them). The holding company will control Pioneer's U.S. operations, including PIM. The holding company also will own 66.7% of Pioneer's and SAM's combined operations outside the U.S., while Banco Santander will own directly the remaining 33.3% stake. The closing of the Transaction is expected to happen in 2016, subject to certain regulatory and other approvals. Under the Investment Company Act of 1940, completion of the Transaction will cause each fund's current investment advisory agreement with PIM to terminate. Accordingly, each fund's Board of Trustees will be asked to approve a new investment advisory agreement. If approved by the Board, each fund's new investment advisory agreement will be submitted to the shareholders of the fund for their approval. Qualified interest income is exempt from nonresident alien (NRA) tax withholding. The percentage of the Fund's ordinary income distributions derived from qualified interest income was 65.9%. Subsequent Events (unaudited) Effective November 2, 2015, Boston Financial Data Service became the transfer agent to the Fund at negotiated rates. 66 Pioneer Global High Yield Fund | Annual Report | 10/31/15 Approval of Investment Advisory Agreement Pioneer Investment Management, Inc. (PIM) serves as the investment adviser to Pioneer Global High Yield Fund (the Fund) pursuant to an investment advisory agreement between PIM and the Fund. In order for PIM to remain the investment adviser of the Fund, the Trustees of the Fund must determine annually whether to renew the investment advisory agreement for the Fund. The contract review process began in January 2015 as the Trustees of the Fund agreed on, among other things, an overall approach and timeline for the process. Contract review materials were provided to the Trustees in March 2015 and July 2015. Supplemental contract review materials were provided to the Trustees in September 2015. In addition, the Trustees reviewed and discussed the Fund's performance at regularly scheduled meetings throughout the year and took into account other information related to the Fund provided to the Trustees at regularly scheduled meetings in connection with the review of the Fund's investment advisory agreement. In March 2015, the Trustees, among other things, discussed the memorandum provided by Fund counsel that summarized the legal standards and other considerations that are relevant to the Trustees in their deliberations regarding the renewal of the investment advisory agreement, and reviewed and discussed the qualifications of the investment management teams, as well as the level of investment by the Fund's portfolio managers in the Fund. In July 2015, the Trustees, among other things, reviewed the Fund's management fee and total expense ratios, the financial statements of PIM and its parent companies, the profitability analyses provided by PIM, and possible economies of scale. The Trustees also reviewed the profitability of the institutional business of PIM and PIM's affiliate, Pioneer Institutional Asset Management, Inc. (together with PIM, "Pioneer"), as compared to that of PIM's fund management business, and considered the differences between the fees and expenses of the Fund and the fees and expenses of Pioneer's institutional accounts, as well as the different services provided by PIM to the Fund and by Pioneer to the institutional accounts. The Trustees further considered contract review materials in September 2015. At a meeting held on September 15, 2015, based on their evaluation of the information provided by PIM and third parties, the Trustees of the Fund, including the Independent Trustees voting separately, unanimously approved the renewal of the investment advisory agreement for another year. In approving the renewal of the investment advisory agreement, the Trustees considered various factors that they determined were relevant, including the factors described below. The Trustees did not identify any single factor as the controlling factor in determining to approve the renewal of the agreement. Pioneer Global High Yield Fund | Annual Report | 10/31/15 67 Nature, Extent and Quality of Services The Trustees considered the nature, extent and quality of the services that had been provided by PIM to the Fund, taking into account the investment objective and strategy of the Fund. The Trustees also reviewed PIM's investment approach for the Fund and its research process. The Trustees considered the resources of PIM and the personnel of PIM who provide investment management services to the Fund. They also reviewed the amount of non-Fund assets managed by the portfolio managers of the Fund. The Trustees considered the non-investment resources and personnel of PIM involved in PIM's services to the Fund, including PIM's compliance and legal resources and personnel. The Trustees noted the substantial attention and high priority given by PIM's senior management to the Pioneer fund complex. The Trustees considered that PIM supervises and monitors the performance of the Fund's service providers and provides the Fund with personnel (including Fund officers) and other resources that are necessary for the Fund's business management and operations. The Trustees also considered that, as administrator, PIM is responsible for the administration of the Fund's business and other affairs. The Trustees considered the fees paid to PIM for the provision of administration services. Based on these considerations, the Trustees concluded that the nature, extent and quality of services that had been provided by PIM to the Fund were satisfactory and consistent with the terms of the investment advisory agreement. Performance of the Fund In considering the Fund's performance, the Trustees regularly review and discuss throughout the year data prepared by PIM and information comparing the Fund's performance with the performance of its peer group of funds as classified by each of Morningstar, Inc. (Morningstar) and Lipper, and with the performance of the Fund's benchmark index. They discussed the Fund's performance with PIM on a more frequent basis in light of the Fund's unfavorable performance compared to its benchmark index and peers over certain periods. The Trustees noted PIM's explanation for the Fund's relative performance and the steps taken by PIM to address the Fund's performance, including enhancing the investment process used for the Fund and reducing the Fund's emerging markets exposure. The Trustees' reviews and discussions, including the steps taken by PIM to address the Fund's performance, were factored into the Trustees' deliberations concerning the renewal of the advisory agreement. 68 Pioneer Global High Yield Fund | Annual Report | 10/31/15 Management Fee and Expenses The Trustees considered information showing the fees and expenses of the Fund in comparison to the management fees and expense ratios of its peer group of funds as classified by Morningstar and also to the expense ratios of a peer group of funds selected on the basis of criteria determined by the Independent Trustees for this purpose using data provided by Strategic Insight Mutual Fund Research and Consulting, LLC (Strategic Insight), an independent third party. In all quintile rankings referred to below, first quintile is most favorable to the Fund's shareowners. The Trustees considered that the Fund's management fee for the most recent fiscal year was in the third quintile relative to the management fees paid by other funds in its Morningstar peer group for the comparable period. The Trustees also considered the breakpoints in the management fee schedule and the reduced fee rates above certain asset levels. The Trustees considered that the expense ratio of the Fund's Class A shares for the most recent fiscal year was in the fourth quintile relative to its Morningstar peer group and in the fourth quintile relative its Strategic Insight peer group, in each case for the comparable period. The Trustees considered that the expense ratio of the Fund's Class Y shares for the most recent fiscal year was in the fourth quintile relative to its Morningstar peer group and in the fourth quintile relative its Strategic Insight peer group, in each case for the comparable period. The Trustees considered the impact of transfer agency, sub-transfer agency and other non-management fee expenses on the expense ratios of the Fund, and noted the impact of expenses relating to small accounts and omnibus accounts on transfer and sub-transfer agency expenses generally. The Trustees noted that they separately review the Fund's transfer agency, sub-transfer agency and intermediary arrangements. The Trustees reviewed management fees charged by Pioneer to institutional and other clients, including publicly offered European funds sponsored by affiliates of Pioneer, unaffiliated U.S. registered investment companies (in a sub-advisory capacity), and unaffiliated foreign and domestic separate accounts. The Trustees also considered PIM's costs in providing services to the Fund and Pioneer's costs in providing services to the other clients and considered the differences in management fees and profit margins for Fund and non-Fund services. In evaluating the fees associated with Pioneer's client accounts, the Trustees took into account the respective demands, resources and complexity associated with the Fund and client accounts. The Trustees noted that, in some instances, the fee rates for those clients were lower than the management fee for the Fund and considered that, under the investment advisory agreement with the Fund, PIM performs additional services for the Fund that it does not provide to those other clients or services that are broader in scope, including oversight of the Fund's other service providers and Pioneer Global High Yield Fund | Annual Report | 10/31/15 69 activities related to compliance and the extensive regulatory and tax regimes to which the Fund is subject. The Trustees also considered the different entrepreneurial risks associated with PIM's management of the Fund and Pioneer's management of the other client accounts. The Trustees concluded that the management fee payable by the Fund to PIM was reasonable in relation to the nature and quality of the services provided by PIM to the Fund. Profitability The Trustees considered information provided by PIM regarding the profitability of PIM with respect to the advisory services provided by PIM to the Fund, including the methodology used by PIM in allocating certain of its costs to the management of the Fund. The Trustees also considered PIM's profit margin in connection with the overall operation of the Fund. They further reviewed the financial results realized by PIM and its affiliates from non-fund businesses. The Trustees considered PIM's profit margins with respect to the Fund in comparison to the limited industry data available and noted that the profitability of any adviser was affected by numerous factors, including its organizational structure and method for allocating expenses. The Trustees concluded that PIM's profitability with respect to the management of the Fund was not unreasonable. Economies of Scale The Trustees considered PIM's views relating to economies of scale in connection with the Pioneer Funds as fund assets grow and the extent to which any such economies of scale are shared with funds and fund shareholders. The Trustees noted the breakpoints in the management fee schedule. The Trustees recognize that economies of scale are difficult to identify and quantify, and that, among other factors that may be relevant, are the following: fee levels, expense subsidization, investment by PIM in research and analytical capabilities and PIM's commitment and resource allocation to the Fund. The Trustees noted that profitability also may be an indicator of the availability of any economies of scale, although profitability may vary for other reasons including due to reductions in expenses. The Trustees concluded that economies of scale, if any, were being appropriately shared with the Funds. Other Benefits The Trustees considered the other benefits to PIM from its relationship with the Fund. The Trustees considered the character and amount of fees paid by the Fund, other than under the investment advisory agreement, for services 70 Pioneer Global High Yield Fund | Annual Report | 10/31/15 provided by PIM and its affiliates. The Trustees further considered the revenues and profitability of PIM's businesses other than the fund business. Pioneer is the principal U.S. asset management business of Pioneer Global Asset Management, the worldwide asset management business of UniCredit Group, which manages over $150 billion in assets (including the Funds). Pioneer and the Funds receive reciprocal intangible benefits from the relationship, including mutual brand recognition and, for the Funds, direct and indirect access to the resources of a large global asset manager. The Trustees concluded that any such benefits received by Pioneer as a result of its relationship with the Funds were reasonable and their consideration of the advisory agreement between the Fund and PIM and the fees thereunder were unaffected by Pioneer's possible receipt of any such intangible benefits. Conclusion After consideration of the factors described above as well as other factors, the Trustees, including all of the Independent Trustees, concluded that the investment advisory agreement between PIM and the Fund, including the fees payable thereunder, was fair and reasonable and voted to approve the proposed renewal of the investment advisory agreement for the Fund.

All year, investors focused on the Federal Reserve System's (the Fed's) deliberations over when to begin normalizing interest rates. However, while there were signs of gradual economic improvement in the U.S., economies abroad increasingly diverged. In June, for example, investors grew concerned about the debt crisis in Greece. That news, in turn, was followed by evidence of an economic slowdown in China, which only served to exacerbate existing worries about growth trends in the emerging markets, a segment of the global economy already being negatively impacted by slumping commodity prices, including the price of crude oil, which has been in near-steady decline for almost a year. Through September 30, 2015, the pockets of heightened market volatility alluded to above had resulted in the Standard & Poor's 500 Index turning in a negative (-5.27%) return over the first nine months of the year. However, the S&P 500 recovered nicely in October, returning 8.43% for the month, which boosted the index's year-to-date return into positive territory, at 2.71%. Despite the headwinds still vexing the global economy, our longer-term view of the U.S. economy has remained positive. Economic conditions in the U.S. have generally been constructive, based largely on improvements in employment statistics and an uptick in the housing sector, which has aided the consumer side of the economy, where household spending has been rising modestly. U.S. consumers also stand to benefit, potentially, from lower energy prices as the winter weather approaches. We continue to believe the U.S. economy remains on a slow, steady growth trend, and that it is unlikely to be disrupted by a slow pace of interest-rate normalization by the Fed. Pioneer Investments believes that investors in today's environment can potentially benefit from the consistent and disciplined investment approach we have used since our founding in 1928. We focus on identifying value across global markets using proprietary research, careful risk management, and a long-term perspective. Our ongoing goal is to produce compelling returns consistent with the stated objectives of our investment products, and with our shareowners' expectations. We believe our shareowners can benefit from the experience and tenure of our investment teams as well as the insights generated from our extensive research process. 2 Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 As always, and particularly during times of market uncertainty, we encourage you to work with your financial advisor to develop an overall investment plan that addresses both your short- and long-term goals, and to implement such a plan in a disciplined manner. We greatly appreciate your trust in us in the past and look forward to continuing to serve you in the future. Sincerely, /s/ Lisa M. Jones Lisa M.

Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 3 Portfolio Management Discussion | 10/31/15 The U.S. dollar acted as a bulwark among world currencies during the 12-month period ended October 31, 2015, a period marked by shifting investor sentiments and growing uncertainties in the fixed-income markets. In the following interview, Charles Melchreit and Paresh Upadhyaya discuss the factors that affected the performance of Pioneer Global Multisector Income Fund during the 12-month period. Mr. Melchreit, Director of Investment-Grade Management, a senior vice president and a portfolio manager at Pioneer, and Mr. Upadhyaya, a senior vice president and portfolio manager at Pioneer, are responsible for the day-to-day management of the Fund, along with Kenneth J. Taubes, Executive Vice President, Chief Investment Officer, U.S., and a portfolio manager at Pioneer, and Andrew Feltus, Director of High Yield and Bank Loans, a senior vice president and a portfolio manager at Pioneer. Q How did the Fund perform during the 12 months ended October 31, 2015? A Pioneer Global Multisector Income Fund's Class A shares returned -1.00% at net asset value during the 12-month period ended October 31, 2015, while the Fund's benchmark, the Barclays Global Aggregate Bond Index (the Barclays Index), returned -3.07%. During the same period, the average return of the 207 mutual funds in Lipper's Global Income Funds category was -2.89%, and the average return of the 368 mutual funds in Morningstar's World Bond Funds category was -3.85%. Q How would you describe the investment environment during the 12-month period ended October 31, 2015? A Currencies proved to be the dominant factor influencing both risk and opportunity in the global fixed-income markets during the period, as a series of events and emerging trends created uncertainties in the minds of market participants and encouraged investments in the perceived, relative safety of the U.S. dollar. Among the developments that caused investors to re-evaluate their tactics and strategies were: an apparent weakening of economic growth trends across much of the globe, signaled by falling commodity prices in general, and oil prices in particular; the devaluation of the Chinese currency (the yuan), which marked the first devaluation of that currency in its trading band in more than two decades; the re-emergence of the debt crisis in Greece during July 2015, which raised speculation about the future of the European Union; and anticipation that the U.S. Federal Reserve System (the Fed) - which had ended its quantitative easing purchases in late 2014 - would begin to further tighten monetary policy by raising short-term interest rates, even as other large central banks were loosening their policies. 4 Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 Concerns about global economy growth escalated in the second quarter of 2015, as manufacturing activity in China - one of the key economies driving global trends - contracted, and there was notable weakness in fixed- investment growth. Driven by government policy, the Chinese economy during the period continued to undergo a transformation aimed at moving it from a production-based to consumption, or consumer-based economy. The contraction of manufacturing output raised concerns that the country's economy was weaker than had been reported. In response, the Chinese stock market plummeted in value from its peak in mid-June, declining by 32% in just one month. The sell-off raised concerns that China's economy was becoming disorderly, and large divergences developed between the onshore and offshore exchange rates for the yuan, which led to the Chinese government's August decision to devalue the currency. As market worries about China escalated, the prices of oil and other commodities started moving lower for the second time in less than a year, based on fears that a general economic slowdown would not only affect commodity-producing emerging markets economies, but could also hurt developed ones, including the U.S. economy. Meanwhile, as these trends were developing, the government of Greece announced that it would be unable to make its first scheduled repayment of an earlier bailout loan from the International Monetary Fund (IMF). In addition, a referendum vote by the Greek electorate gave overwhelming support to the notion that the Greek government should take a hard line in any discussions with the IMF, the European Central Bank (ECB), and the European commission -- collectively known as "the Troika." However, the Troika signaled that its members might not provide any further assistance to Greece without concessions. In the end, as stocks declined in value and Greek banks were forced to close their doors, the Greek government retreated from its hard-line stance and accepted the Troika's terms. The entire crisis, however, increased turmoil in world currency markets, leading to further weakening of the euro and euro-linked currencies, and further strengthening of the U.S. dollar. In the United States, the Fed indicated throughout the period that it could begin to hike the influential Federal funds rate, as evidence appeared that the domestic economy was strengthening and that the nation's unemployment rate was approaching the Fed's target for a non-accelerating inflation rate of unemployment (NAIRU) of 4.9% -- a level that generally leads to higher wage-inflation rates. (The Fed has kept the Federal funds rate at near zero - between 0.00% and 0.25% - since 2009.) However, the rate hike did not happen before the end of the 12-month period, as the Fed maintained a cautious policy stance, citing global economic instability, Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 5 among other reasons, for delaying a rate increase. Towards the end of the period, however, the Fed did send out new signals that a gradual series of interest-rate hikes could begin in the near future. Q In that environment, how did the Fund's positioning affect performance relative to the Barclays Index during the 12-month period ended October 31, 2015? A In a challenging period for investing in global fixed-income markets, the Fund's Class A shares generated slightly negative results. Nevertheless, the Fund solidly outperformed its benchmark, the Barclays Index, and its peer groups during the period. Driving the Fund's benchmark-relative outperformance during the period was our overweighting of the U.S. dollar, an underweight in major foreign currencies, and short portfolio positions held in those same foreign currencies -- notably, the euro and the Japanese yen. Less consequential, but also a factor contributing to the Fund's relative outperformance, was short positioning in some emerging markets currencies. The positive effects of the Fund's emphasis on the U.S. dollar more than offset some factors that detracted, somewhat, from relative returns, including the portfolio's short-duration stance in Europe, where interest rates declined. (Duration is a measure of the sensitivity of the price, or the value of principal, of a fixed-income investment to a change in interest rates, expressed as a number of years). In addition, the Fund's overweighting of the sovereign debt of some emerging markets nations and underweight positions in both U.S. Treasuries and European sovereign bonds detracted from benchmark-relative performance, but not enough to offset the positive effects of the portfolio's overall currency positioning. We maintained a short-duration stance in the Fund's portfolio throughout the 12-month period, but the potentially negative effects of that positioning were more than compensated for by the positive benefits of the aforementioned currency positioning. Q What were the principal factors affecting the Fund's yield during the 12-month period ended October 31, 2015? A Interest rates throughout the globe tended to decline during the 12 months. Consequently, the Fund's dividend* yield also declined as new investments - with lower coupon rates - provided less current income than older portfolio investments that had either reached maturity, or were sold. * Dividends are not guaranteed. 6 Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 Q Did the Fund invest in any derivative securities during the 12-month period ended October 31, 2015? If so, did those investments affect the Fund's performance? A Yes, we did invest the Fund in forward currency transactions as part of our strategy to emphasize the U.S. dollar relative to other world currencies. The strategy, which included the use of the derivative securities, provided significant help and contributed to the Fund's outperformance of its benchmark. Conversely, a short portfolio position in U.S. Treasury futures had a slight negative influence on the Fund's performance. In addition, the Fund had a small position in credit default swaps early in the period, which we employed in an attempt to hedge the portfolio's exposure to high-yield securities. The credit default swaps had no material effect on the Fund's results. Q What is your investment outlook? A We remain bullish on the U.S. dollar, especially if the monetary policies of the world's central banks start diverging even further, with the Fed perhaps moving to tighten policy and raise rates at the same time other banks, such as the ECB, continue to ease their policies to facilitate economic growth and reduce deflationary risks in their respective countries or regions. In the absence of any unanticipated increase in inflation or decline in economic growth rates, we expect that the Fed will begin a gradual tightening process by raising interest over a series of steps. With regard to the Fund, we expect to maintain our current strategy that emphasizes the U.S. dollar in the portfolio's currency positioning. At the same time, we anticipate keeping a short-duration stance in the portfolio, given our previously stated belief that the Fed will soon begin to raise short-term interest rates. Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 7 Please refer to the Schedule of Investments on pages 17-36 for a full listing of Fund securities. Investing in foreign and/or emerging markets securities involves risks relating to interest rates, currency exchange rates, and economic and political conditions. 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 issuers 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 price volatility, illiquidity and possibility of default. Prepayment risk is the chance that an issuer may exercise its right to prepay its security, if falling interest rates prompt the issuer to do so. 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. The Fund 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 securities issued by U.S. Government-sponsored entities (e.g., FNMA, Freddie Mac) are neither guaranteed nor issued by the U.S. Government. Floating rate loans and similar instruments may be illiquid or less liquid than other instruments, and the value of any collateral can decline or be insufficient to meet the issuer's obligations. The value of municipal securities can be adversely affected by changes in financial condition of municipal issuers, lower revenues, and regulatory and political developments. The Fund is subject to currency risk, meaning that the Fund could experience losses based on changes in the exchange rate between non-U.S. currencies and the U.S. dollar. The Fund may use derivatives, such as options, futures, inverse floating rate obligations, swaps, and others, which can be illiquid, may disproportionately increase losses, and have a potentially large impact on Fund performance. Derivatives may have a leveraging effect on the Fund. These risks may increase share price volatility. Before investing, consider the product's investment objectives, risks, charges and expenses.

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 Multisector Income Fund Based on actual returns from May 1, 2015, through October 31, 2015. -------------------------------------------------------------------------------- Share Class A C Y -------------------------------------------------------------------------------- Beginning Account Value on 5/1/15 $1,000.00 $1,000.00 $1,000.00 -------------------------------------------------------------------------------- Ending Account Value (after expenses) on 10/31/15 $ 983.02 $ 978.66 $ 984.55 -------------------------------------------------------------------------------- Expenses Paid During Period* $ 5.00 $ 9.48 $ 3.75 -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.00%, 1.90%, and 0.75% for Class A, Class C and Class Y shares, respectively, multiplied by the average account value over the period, multiplied by 184/365 (to reflect the one-half year period). Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 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. Expenses Paid on a $1,000 Investment in Pioneer Global Multisector Income Fund Based on a hypothetical 5% return per year before expenses, reflecting the period from May 1, 2015, through October 31, 2015. -------------------------------------------------------------------------------- Share Class A C Y -------------------------------------------------------------------------------- Beginning Account Value on 5/1/15 $1,000.00 $1,000.00 $1,000.00 -------------------------------------------------------------------------------- Ending Account Value (after expenses) on 10/31/15 $1,020.16 $1,015.63 $1,021.42 -------------------------------------------------------------------------------- Expenses Paid During Period* $ 5.09 $ 9.65 $ 3.82 -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.00%, 1.90%, and 0.75% for Class A, Class C and Class Y 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 Multisector Income Fund | Annual Report | 10/31/15 Schedule of Investments | 10/31/15 ------------------------------------------------------------------------------------------------------ Floating Principal Rate (b) Amount ($) (unaudited) Value ------------------------------------------------------------------------------------------------------ CONVERTIBLE CORPORATE BONDS -- 0.3% CAPITAL GOODS -- 0.1% Electrical Components & Equipment -- 0.1% 56,000 General Cable Corp., 4.5%, 11/15/29 (Step) $ 38,255 -------------- Total Capital Goods $ 38,255 ------------------------------------------------------------------------------------------------------ CONSUMER DURABLES & APPAREL -- 0.2% Homebuilding -- 0.2% 50,000 KB Home, 1.375%, 2/1/19 $ 45,969 -------------- Total Consumer Durables & Apparel $ 45,969 ------------------------------------------------------------------------------------------------------ TOTAL CONVERTIBLE CORPORATE BONDS (Cost $105,600) $ 84,224 ------------------------------------------------------------------------------------------------------ PREFERRED STOCKS -- 0.7% BANKS -- 0.3% Diversified Banks -- 0.3% 724 7.88 Citigroup Capital XIII, Floating Rate Note, 10/30/40 $ 18,390 2,610 7.12 Citigroup, Inc., Floating Rate Note (Perpetual) 71,958 242 6.00 US Bancorp, Floating Rate Note (Perpetual) 6,486 -------------- $ 96,834 -------------- Total Banks $ 96,834 ------------------------------------------------------------------------------------------------------ DIVERSIFIED FINANCIALS -- 0.3% Consumer Finance -- 0.2% 25 Ally Financial, Inc., 7.0% (Perpetual) (144A) $ 25,604 850 8.12 GMAC Capital Trust I, Floating Rate Note, 2/15/40 21,956 -------------- $ 47,560 ------------------------------------------------------------------------------------------------------ Asset Management & Custody Banks -- 0.1% 1,000 5.90 State Street Corp., Floating Rate Note, 12/31/73 $ 26,620 -------------- Total Diversified Financials $ 74,180 ------------------------------------------------------------------------------------------------------ INSURANCE -- 0.1% Property & Casualty Insurance -- 0.1% 1,545 5.10 The Allstate Corp., Floating Rate Note, 1/15/53 $ 39,753 -------------- Total Insurance $ 39,753 ------------------------------------------------------------------------------------------------------ TOTAL PREFERRED STOCKS (Cost $194,916) $ 210,767 ------------------------------------------------------------------------------------------------------ CONVERTIBLE PREFERRED STOCKS -- 0.3% BANKS -- 0.3% Diversified Banks -- 0.3% 80 Wells Fargo & Co., 7.5% (Perpetual) $ 94,800 -------------- Total Banks $ 94,800 ------------------------------------------------------------------------------------------------------ TOTAL CONVERTIBLE PREFERRED STOCKS (Cost $83,502) $ 94,800 ------------------------------------------------------------------------------------------------------ The accompanying notes are an integral part of these financial statements.

Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 43 Notes to Financial Statements | 10/31/15 1. Organization and Significant Accounting Policies Pioneer Global Multisector Income 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 a high level of current income. The Fund offers three classes of shares designated as Class A, Class C, and Class Y shares. 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 of Trustees 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: 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 are valued at prices supplied by independent pricing services, which consider such factors as market prices, market events, quotations from 44 Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 one or more brokers, Treasury spreads, yields, maturities and ratings. 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. If price information is not available from Loan Pricing Corporation, or if the price information is deemed to be unreliable, price information will be obtained from an alternative loan interest pricing service. If no reliable price quotes are available from either the primary or alternative pricing service, broker quotes will be solicited. Event-linked bonds are valued at the bid price obtained from an independent third party pricing service. Other insurance-linked securities may be valued at the bid price obtained from an independent pricing service, or through a third party using a pricing matrix, insurance industry valuation models, or other fair value methods or techniques to provide an estimated value of the instrument. 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. Cash may include overnight time deposits at approved financial institutions. 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. Securities or senior loans for which market prices and/or quotations are not readily available or are considered to be unreliable are valued by a fair valuation team comprised of certain personnel of Pioneer Investment Management, Inc. (PIM), the Fund's investment adviser, pursuant to procedures adopted by the Fund's Board of Trustees. PIM's fair valuation team uses fair value methods approved by the Valuation Committee of the Board of Trustees. PIM's fair valuation team is responsible for monitoring developments that may impact fair valued securities and for discussing and assessing fair values on an ongoing basis, and at least quarterly, with the Valuation Committee of the Board of Trustees. 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. 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 Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 45 disasters, terrorist activity or trading halts. Thus, the valuation of the Fund's securities may differ significantly from exchange prices and such differences could be material. At October 31, 2015, there were no securities that were valued using fair value methods (other than securities valued using prices supplied by independent pricing services or broker-dealers or through a third party using an insurance industry valuation model). B. Investment Income and Transactions 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 purchase prices of 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. C. 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 the market prices of those securities but are included with the net realized and unrealized gain or loss on investments. 46 Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 D. 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 appreciation or depreciation is recorded in the Fund's financial statements. The Fund records realized gains and losses at the time a contract 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). E. 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 net taxable income and net realized capital gains, if any, to its shareowners. Therefore, no provision for federal income taxes is required. As of October 31, 2015, the Fund did not accrue any interest or penalties with respect to uncertain tax positions, which, if applicable, would be recorded as an income tax expense in the Statement of Operations. Tax returns filed within the prior three years remain subject to examination by federal and state tax authorities. The amount and character of income and capital gain distributions to shareowners are determined in accordance with federal income tax rules, which may differ from U.S. generally accepted accounting principles. Distributions in excess of net investment income or net realized gains are temporary overdistributions for financial statement purposes resulting from differences in the recognition or classification of income or distributions for financial statement and tax purposes. Capital accounts within the financial statements are adjusted for permanent book/tax differences to reflect tax character, but are not adjusted for temporary differences. At October 31, 2015, the Fund reclassified $444,774 to increase undistributed net investment income and $444,774 to increase accumulated net realized loss on investments futures contracts, swap contracts, written options, and foreign currency transactions to reflect permanent book/tax differences. These adjustments have no impact on net assets or the results of operations. At October 31, 2015, the Fund was permitted to carry forward indefinitely $64,518 of long-term losses under the Regulated Investment Company Modernization Act of 2010 without limitation. Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 47 The tax character of distributions paid during the years ended October 31, 2015, and October 31, 2014, were as follows: --------------------------------------------------------------------------- 2015 2014 --------------------------------------------------------------------------- Distributions paid from: Ordinary income $ 856,632 $835,366 Long-term capital gain 238,626 159,919 --------------------------------------------------------------------------- Total $1,095,258 $995,285 =========================================================================== The following shows the components of distributable earnings on a federal income tax basis at October 31, 2015: --------------------------------------------------------------------------- 2015 --------------------------------------------------------------------------- Distributable earnings: Undistributed ordinary income $ 199,660 Capital loss carryforward (64,518) Current year dividend payable (42,347) Unrealized depreciation (1,097,662) --------------------------------------------------------------------------- Total $(1,004,867) =========================================================================== The difference between book-basis and tax-basis net unrealized depreciation is attributable to the tax deferral of losses on wash sales, adjustments related to sidecars, the mark-to-market of forward and futures contracts, and interest accruals on preferred stock. F. 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 $1,700 in underwriting commissions on the sale of Class A shares during the year ended October 31, 2015. G. 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 Fund's transfer agent, 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). 48 Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 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. H. 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 investments 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. I. Insurance Linked Securities (ILS) The Fund invests in event-linked bonds. Event-linked bonds are floating rate debt obligations for which the return of principal and the payment of interest are contingent on the non-occurrence of a pre-defined "trigger" event, such as a hurricane or an earthquake of a specific magnitude. The trigger event's magnitude may be based on losses to a company or industry, industry indexes or readings of scientific instruments, or may be based on specified actual losses. If a trigger event, as defined within the terms of an event-linked bond occurs, the Fund may lose a portion or all of its accrued interest and/or principal invested in such event-linked bond. The Fund is entitled to receive principal and interest payments so long as no trigger event occurs of the description and magnitude specified by the instrument. In addition to the Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 49 specified trigger events, event-linked bonds may expose the Fund to other risks, including but not limited to issuer (credit) default, adverse regulatory or jurisdictional interpretations and adverse tax consequences. The Fund's investments in ILS may include special purpose vehicles ("SPVs") or similar instruments structured to comprise a portion of a reinsurer's catastrophe-oriented business, known as quota share instruments (sometimes referred to as reinsurance sidecars), or to provide reinsurance relating to specific risks to insurance or reinsurance companies through a collateralized instrument, known as collateralized reinsurance. Structured reinsurance investments, which also may include industry loss warranties ("ILWs"), are subject to the same risks as event-linked bonds. In addition, because quota share instruments represent an interest in a basket of underlying reinsurance contracts, the Fund has limited transparency into the individual underlying contracts and therefore must rely upon the risk assessment and sound underwriting practices of the issuer. Accordingly, it may be more difficult for PIM to fully evaluate the underlying risk profile of the Fund's investment in quota share instruments and therefore place the Fund's assets at greater risk of loss than if PIM had more complete information. Quota share instruments and other structured reinsurance instruments generally will be considered illiquid securities by the Fund. These securities may be difficult to purchase, sell or unwind. Illiquid securities also may be difficult to value. If the Fund is forced to sell an illiquid asset, the Fund may be forced to sell at a loss. J. Futures Contracts The Fund may enter into futures transactions in order to attempt 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. The amount of cash deposited with the broker as collateral at October 31, 2015 was $71,550. 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. With futures, there is minimal counterparty credit risk to the Fund since futures are exchange-traded and 50 Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 the exchange's clearinghouse, as counterparty to all exchange-traded futures, guarantees the futures against default. The average value of contracts open during the year ended October 31, 2015, was $(3,154,682). At October 31, 2015, open futures contracts were as follows: ----------------------------------------------------------------------------------------- Net Number of Unrealized Contracts Settlement Appreciation Type Counterparty Long/(Short) Month Value (Depreciation) ----------------------------------------------------------------------------------------- Euro Bond Citibank N.A. 5 12/15 $ 865,166 $ 6,263 US 5 Yr Note (CBT) Citibank N.A. (11) 12/15 (1,317,508) 2,746 US 10 Yr Note (CBT) Citibank N.A. (29) 12/15 (3,702,938) 3,447 ----------------------------------------------------------------------------------------- Total (35) $(4,155,280) $12,456 ========================================================================================= K. Repurchase Agreements Repurchase agreements are arrangements under which the Fund purchases securities from a broker-dealer or a bank, called the counterparty, upon the agreement of the counterparty to repurchase the securities from the Fund at a later date, and at a specific price, which is typically higher than the purchase price paid by the Fund. The securities purchased serve as the Fund's collateral for the obligation of the counterparty to repurchase the securities. The value of the 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, PIM is responsible for determining that the value of the collateral remains at least equal to the repurchase price. In the event of a default by the counterparty, the Fund is entitled to sell the securities, but the Fund may not be able to sell them for the price at which they were purchased, thus causing a loss to the Fund. Additionally, if the counterparty becomes insolvent, there is some risk that the Fund will not have a right to the securities, or the immediate right to sell the securities. As of the year ended October 31, 2015, the Fund had no open repurchase agreements. L. Option Writing The Fund may write put and covered call options to seek to increase total return. When an option is written, the Fund receives a premium and becomes obligated to purchase or sell the underlying security at a fixed price, upon the exercise of the option. When the Fund writes an option, an amount equal to the premium received by the Fund is recorded as a liability and is subsequently adjusted to the current value of the option written. Premiums received from writing options that expire unexercised are treated by the Fund on the expiration date as realized gains from investments. The difference Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 51 between the premium and the amount paid on effecting a closing purchase transaction, including brokerage commissions, is also treated as a realized gain, or, if the premium is less than the amount paid for the closing purchase transaction, as a realized loss. If a call option is exercised, the premium is added to the proceeds from the sale of the underlying security in determining whether the Fund has realized a gain or loss. The Fund as writer of an option bears the market risk of an unfavorable change in the price of the security underlying the written option. The average value of written options contracts open during the year ended October 31, 2015, was $0. There were no written options outstanding as of October 31, 2015. --------------------------------------------------------------------------- Number of Premium Contracts Paid --------------------------------------------------------------------------- Options open at beginning of period 84,202 $ (1,387) Options opened -- -- Options exercised -- -- Options closed -- -- Options expired (84,202) 1,387 --------------------------------------------------------------------------- Options open at end of period -- $ -- =========================================================================== M. 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 sell or buy credit default swap contracts to seek to increase the Fund's income, or to attempt to hedge the risk of default on portfolio securities. A credit default swap index is used to hedge risk or take a position on a basket of credit entities or indices. 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, 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 52 Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 made by the Fund, as the protection buyer, is recorded as an asset in the Statement of Assets and Liabilities. Periodic payments received or paid by the Fund are recorded as realized gains or losses in the Statement of Operations. 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 appreciation or depreciation in the Statement of Assets and Liabilities. 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 in the Statement of Operations. 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. Certain swap contracts that are cleared through a central clearinghouse are referred to as centrally cleared swaps. All payments made or received by the Fund are pursuant to a centrally cleared swap contract with the central clearing party rather than the original counterparty. Upon entering into a centrally cleared swap contract, the Fund is required to make an initial margin deposit, either in cash or in securities. The daily change in value on open centrally cleared contracts is recorded as variation margin on centrally cleared swaps on the Statement of Assets and Liabilities. Open credit default swap contracts at October 31, 2015, are listed in the Schedule of Investments. The average value of swap contracts open during the year ended October 31, 2015 was $14,698. 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%, 1.90% and 0.75% of the average daily net assets attributable to Class A, Class C and Class Y shares, respectively. Fees waived and expenses reimbursed during the year ended October 31, 2015, are reflected on the Statement of Operations. These expense Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 53 limitations are in effect through March 1, 2017. 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 from affiliates" reflected on the Statement of Assets and Liabilities is $13,184 in management fees, administrative costs and certain other reimbursements due to PIM at October 31, 2015. 3. Transfer Agent Pioneer Investment Management Shareholder Services, Inc. (PIMSS), a wholly owned indirect subsidiary of UniCredit, provided substantially all transfer agent and shareowner services to the Fund at negotiated rates. In addition, the Fund reimbursed PIMSS for out-of-pocket expenses incurred by PIMSS related to shareholder communications activities such as proxy and statement mailings, outgoing phone calls and omnibus relationship contracts. For the year ended October 31, 2015, such out-of-pocket expenses by class of shares were as follows: -------------------------------------------------------------------------------- Shareholder Communications: -------------------------------------------------------------------------------- Class A $118,880 Class C 2,840 Class Y 1,295 -------------------------------------------------------------------------------- Total $123,015 ================================================================================ Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $38,940 in transfer agent fees and out-of-pocket reimbursements payable to PIMSS at October 31, 2015. 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 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 C shares. The fee for Class C shares consists of a 0.25% service fee and a 0.75% distribution fee paid as compensation for personal services and/or account maintenance services or 54 Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 distribution services with regard to Class C shares. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $598 in distribution fees payable to PFD at October 31, 2015. In addition, redemptions of each class of shares (except Class Y 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 12 months of purchase. Redemptions of Class C shares within 12 months 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 shares. Proceeds from the CDSCs are paid to PFD. For the year ended October 31, 2015, CDSCs in the amount of $784 were paid to PFD. 5. Expense Offset Arrangements The Fund entered into certain expense offset arrangements with PIMSS which may result in a reduction in the Fund's total expenses due to interest earned on cash held by PIMSS. For the year ended October 31, 2015, the Fund's expenses were not reduced under such arrangements. 6. Forward Foreign Currency Contracts At October 31, 2015, the Fund had entered into various forward foreign currency contracts that obligate the Fund to deliver or take delivery of currencies at specified future maturity dates. Alternatively, prior to the settlement date of a forward foreign currency contract, the Fund may close out such contract by entering into an offsetting contract. The average value of forward foreign currency contracts open during the year ended October 31, 2015, was $(6,657,098). Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 55 Open forward foreign currency contracts at October 31, 2015, were as follows: ------------------------------------------------------------------------------------------------ In Currency Currency Exchange Settlement Unrealized Sold Deliver Purchased For Counterparty Date Appreciation ------------------------------------------------------------------------------------------------ USD (1,291,743) CAD 1,700,232 Citibank NA 11/2/15 $ 7,980 ZAR (1,555,000) USD 114,980 Citibank NA 11/16/15 2,805 CZK (13,500,000) USD 549,068 Citibank NA 11/5/15 607 SEK (2,751,185) USD 330,467 JP Morgan 11/27/15 7,803 Chase Bank HUF (66,994,656) USD 242,441 JP Morgan 12/16/15 5,216 Chase Bank CLP (91,560,000) USD 134,009 JP Morgan 12/16/15 2,041 Chase Bank SGD (144,956) USD 104,949 JP Morgan 11/5/15 1,425 Chase Bank CAD (122,754) MXN 1,557,353 JP Morgan 11/24/15 391 Chase Bank ------------------------------------------------------------------------------------------------ Total $28,268 ================================================================================================ ------------------------------------------------------------------------------------------------ In Currency Currency Exchange Settlement Unrealized Sold Deliver Purchased For Counterparty Date Depreciation ------------------------------------------------------------------------------------------------ GBP (595,330) USD 917,719 Brown Brothers 12/29/15 $ (591) Harriman and Co.

Assets and Liabilities Offsetting The Fund has entered into an International Swaps and Derivatives Association, Inc. Master Agreement ("ISDA Master Agreement") or similar agreement with substantially all its derivative counterparties. An ISDA Master Agreement is a bilateral agreement between the Fund and a counterparty that governs the trading of certain OTC derivatives and typically contains, among other things, close-out and set-off provisions which apply upon the occurrence of event of a default and/or termination event as defined under the relevant ISDA Master Agreement. The ISDA Master Agreement may also give a party the right to terminate all transactions traded under such agreement if, among other things, there is deterioration in the credit quality of the other party. Upon an event of 56 Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 default or a termination of the ISDA Master Agreement, the non-defaulting party has the right to close out all transactions under such agreement and to net amounts owed under each transaction to determine one net amount payable by one party to the other. The right to close out and net payments across all transactions under the ISDA Master Agreement could result in a reduction of the Fund's credit risk to its counterparty equal to any amounts payable by the Fund under the applicable transactions, if any. However, the Fund's right to setoff may be restricted or prohibited by the bankruptcy or insolvency laws of the particular jurisdiction to which a specific ISDA counterparty is subject. The collateral requirements for derivatives transactions under an ISDA Master Agreement are governed by a credit support annex to the ISDA Master Agreement. Collateral requirements are generally determined at the close of business each day and are typically based on changes in market values for each transaction under an ISDA Master Agreement and netted into one amount for such agreement. Generally, the amount of collateral due from or to a counterparty is subject to threshold (a "minimum transfer amount") before a transfer is required, which may vary by counterparty. Collateral pledged for the benefit of the Fund and/or counterparty is held in segregated accounts by the Fund's custodian and cannot be sold, re-pledged, assigned or otherwise used while pledged. Cash that has been segregated to cover the Fund's collateral obligations, if any, will be reported separately in the Statement of Assets and Liabilities as "Futures collateral", "Swap Collateral" or "Deposit with broker." Securities pledged by the Fund as collateral, if any, are identified as such in the Schedule of Investments. Financial instruments subject to an enforceable master netting agreement such as an ISDA Master Agreement have been offset on the Statement of Assets and Liabilities. The following charts show gross assets and liabilities of the Fund as of October 31, 2015. -------------------------------------------------------------------------------------------- Derivative Assets Subject to Derivatives Non-Cash Cash Net Amount Master Netting Available Collateral Collateral of Derivative Counterparty Agreement for Offset Received (a) Received (a) Assets (b) -------------------------------------------------------------------------------------------- J.P.

Additional Disclosures about Derivative Instruments and Hedging Activities The Fund's use of derivatives subjects it to the following risks: Interest rate risk relates to the fluctuations in the value of interest-bearing securities due to changes in the prevailing levels of market interest rates. Credit risk relates to the ability of the issuer of a financial instrument to make further principal or interest payments on an obligation or commitment that it has to the Fund. Foreign exchange rate risk relates to fluctuations in the value of an asset or liability due to changes in currency exchange rates. Equity risk relates to the fluctuations in the value of financial instruments as a result of changes in market prices (other than those arising from interest rate risk or foreign exchange risk), whether caused by factors specific to an individual investment, its issuer, or all factors affecting all instruments traded in a market or market segment. Commodity risk relates to the risk that the value of a commodity or commodity index will fluctuate based on increases or decreases in the commodities market and factors specific to a particular industry or commodity. 58 Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 The fair value of open derivative instruments (not considered to be hedging instruments for accounting disclosure purposes) by risk exposure at October 31, 2015, was as follows: --------------------------------------------------------------------------------------------- Foreign Statement of Assets Interest Credit Exchange Equity Commodity and Liabilities Rate Risk Risk Rate Risk Risk Risk --------------------------------------------------------------------------------------------- Assets Unrealized appreciation on futures contracts $12,456 $ -- $ -- $ -- $ -- Net unrealized appreciation on swap contracts -- 4,547 -- -- -- Unrealized appreciation of forward foreign currency contracts -- -- 28,268 -- -- --------------------------------------------------------------------------------------------- Total Value $12,456 $ 4,547 $ 28,268 $ -- $ -- --------------------------------------------------------------------------------------------- Liabilities Unrealized depreciation of forward foreign currency contracts $ -- $ -- $(220,639) $ -- $ -- --------------------------------------------------------------------------------------------- Total Value $ -- $ -- $(220,639) $ -- $ -- --------------------------------------------------------------------------------------------- The effect of derivative instruments (not considered to be hedging instruments for accounting disclosure purposes) on the Statement of Operations by risk exposure at October 31, 2015, was as follows: ---------------------------------------------------------------------------------------------- Foreign Statement of Interest Credit Exchange Equity Commodity Operations Rate Risk Risk Rate Risk Risk Risk ---------------------------------------------------------------------------------------------- Net realized gain (loss) on Swap contracts $ -- $ (14) $ -- $ -- $ -- Futures contracts (67,585) -- -- -- -- Written options -- -- 1,387 -- -- Forward foreign currency contracts -- -- 1,268,305 -- -- ---------------------------------------------------------------------------------------------- Total Value $(67,585) $ (14) $1,269,692 $ -- $ -- ---------------------------------------------------------------------------------------------- Change in net unrealized appreciation (depreciation) on Swap contracts $ -- $4,599 $ -- $ -- $ -- Futures contracts 30,465 -- -- -- -- Written options -- -- (1,386) -- -- Forward foreign currency contracts -- -- (288,758) -- -- ---------------------------------------------------------------------------------------------- Total Value $ 30,465 $4,599 $ (290,144) $ -- $ -- ---------------------------------------------------------------------------------------------- Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 59 9.

Line of Credit Facility The Fund, along with certain other funds in the Pioneer Family of Funds (the Funds), participates in a 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. The credit facility in effect until June 9, 2015, was in the amount of $215 million. As of June 9, 2015, the facility is in the amount of $240 million. Under such facility, depending on the type of loan, interest on borrowings is payable at the London Interbank Offered Rate (LIBOR) plus 0.85% on an annualized basis, or the Alternate Base Rate, which is the greater of (a) the facility's administrative agent's daily announced prime rate on the borrowing date, (b) 2% plus the Federal Funds Rate on the borrowing date and (c) 2% plus the overnight Eurodollar rate on the borrowing date. The Funds pay an annual commitment fee to participate in a credit 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, 2015, the Fund had no borrowings under the credit facility. 60 Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 Report of Independent Registered Public Accounting Firm To the Board of Trustees of Pioneer Series Trust VII and the Shareowners of Pioneer Global Multisector Income Fund: -------------------------------------------------------------------------------- We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Pioneer Global Multisector Income Fund (one of the funds constituting Pioneer Series Trust VII), as of October 31, 2015, and the related statement of operations for the year then ended and the statements of changes in net assets and the financial highlights for each of the two years in the period then ended. 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. The financial highlights for the years ended October 31, 2013, 2012, and 2011 were audited by other auditors. Those auditors expressed an unqualified opinion on those financial statements and financial highlights in their report dated December 23, 2013. 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. The Fund is not required to have, nor were we engaged to perform, an audit of its 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, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of October 31, 2015, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. 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 Multisector Income Fund as of October 31, 2015, and the results of its operations for the year then ended, and the changes in its net assets and the financial highlights for each of the two years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. /s/ Deloitte & Touche LLP Boston, Massachusetts December 23, 2015 Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 61 Additional Information Qualified interest income is exempt from nonresident alien (NRA) tax withholding. The percentage of the Fund's ordinary income distributions derived from qualified interest income was 41.27%. PIM, the Fund's investment adviser, is currently an indirect, wholly owned subsidiary of UniCredit. On November 11, 2015, UniCredit announced that it signed a binding master agreement with Banco Santander and affiliates of Warburg Pincus and General Atlantic (the "Private Equity Firms") with respect to Pioneer Investments ("Pioneer") and Santander Asset Management ("SAM") (the "Transaction"). The Transaction, as previously announced by UniCredit, will establish a holding company, with the name Pioneer Investments, to be owned by UniCredit (50%) and the Private Equity Firms (50% between them). The holding company will control Pioneer's U.S. operations, including the Adviser. The holding company also will own 66.7% of Pioneer's and SAM's combined operations outside the U.S., while Banco Santander will own directly the remaining 33.3% stake. The closing of the Transaction is expected to happen in 2016, subject to certain regulatory and other approvals. Under the Investment Company Act of 1940, completion of the Transaction will cause the Fund's current investment advisory agreement with PIM to terminate. Accordingly, the Fund's Board of Trustees will be asked to approve a new investment advisory agreement. If approved by the Board, the Fund's new investment advisory agreement will be submitted to the shareholders of the Fund for their approval. Subsequent Event (unaudited) Effective November 2, 2015, Boston Financials Data Service became the transfer agent to the Fund at negotiated rates. 62 Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 Approval of Investment Advisory Agreement Pioneer Investment Management, Inc. (PIM) serves as the investment adviser to Pioneer Global Multisector Income Fund (the Fund) pursuant to an investment advisory agreement between PIM and the Fund. In order for PIM to remain the investment adviser of the Fund, the Trustees of the Fund must determine annually whether to renew the investment advisory agreement for the Fund. The contract review process began in January 2015 as the Trustees of the Fund agreed on, among other things, an overall approach and timeline for the process. Contract review materials were provided to the Trustees in March 2015 and July 2015. Supplemental contract review materials were provided to the Trustees in September 2015. In addition, the Trustees reviewed and discussed the Fund's performance at regularly scheduled meetings throughout the year and took into account other information related to the Fund provided to the Trustees at regularly scheduled meetings in connection with the review of the Fund's investment advisory agreement. In March 2015, the Trustees, among other things, discussed the memorandum provided by Fund counsel that summarized the legal standards and other considerations that are relevant to the Trustees in their deliberations regarding the renewal of the investment advisory agreement, and reviewed and discussed the qualifications of the investment management teams, as well as the level of investment by the Fund's portfolio managers in the Fund. In July 2015, the Trustees, among other things, reviewed the Fund's management fee and total expense ratios, the financial statements of PIM and its parent companies, the profitability analyses provided by PIM, and possible economies of scale. The Trustees also reviewed the profitability of the institutional business of PIM and PIM's affiliate, Pioneer Institutional Asset Management, Inc. (together with PIM, "Pioneer"), as compared to that of PIM's fund management business, and considered the differences between the fees and expenses of the Fund and the fees and expenses of Pioneer's institutional accounts, as well as the different services provided by PIM to the Fund and by Pioneer to the institutional accounts. The Trustees further considered contract review materials in September 2015. At a meeting held on September 15, 2015, based on their evaluation of the information provided by PIM and third parties, the Trustees of the Fund, including the Independent Trustees voting separately, unanimously approved the renewal of the investment advisory agreement for another year. In approving the renewal of the investment advisory agreement, the Trustees Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 63 considered various factors that they determined were relevant, including the factors described below. The Trustees did not identify any single factor as the controlling factor in determining to approve the renewal of the agreement. Nature, Extent and Quality of Services The Trustees considered the nature, extent and quality of the services that had been provided by PIM to the Fund, taking into account the investment objective and strategy of the Fund. The Trustees also reviewed PIM's investment approach for the Fund and its research process. The Trustees considered the resources of PIM and the personnel of PIM who provide investment management services to the Fund. They also reviewed the amount of non-Fund assets managed by the portfolio managers of the Fund. The Trustees considered the non-investment resources and personnel of PIM involved in PIM's services to the Fund, including PIM's compliance and legal resources and personnel. The Trustees noted the substantial attention and high priority given by PIM's senior management to the Pioneer fund complex. The Trustees considered that PIM supervises and monitors the performance of the Fund's service providers and provides the Fund with personnel (including Fund officers) and other resources that are necessary for the Fund's business management and operations. The Trustees also considered that, as administrator, PIM is responsible for the administration of the Fund's business and other affairs. The Trustees considered the fees paid to PIM for the provision of administration services. Based on these considerations, the Trustees concluded that the nature, extent and quality of services that had been provided by PIM to the Fund were satisfactory and consistent with the terms of the investment advisory agreement. Performance of the Fund In considering the Fund's performance, the Trustees regularly review and discuss throughout the year data prepared by PIM and information comparing the Fund's performance with the performance of its peer group of funds as classified by each of Morningstar, Inc. (Morningstar) and Lipper, and with the performance of the Fund's benchmark index. They also discuss the Fund's performance with PIM on a regular basis. The Trustees' regular reviews and discussions were factored into the Trustees' deliberations concerning the renewal of the advisory agreement. 64 Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 Management Fee and Expenses The Trustees considered information showing the fees and expenses of the Fund in comparison to the management fees and expense ratios of its peer group of funds as classified by Morningstar and also to the expense ratios of a peer group of funds selected on the basis of criteria determined by the Independent Trustees for this purpose using data provided by Strategic Insight Mutual Fund Research and Consulting, LLC (Strategic Insight), an independent third party. In all quintile rankings referred to below, first quintile is most favorable to the Fund's shareowners. The Trustees considered that the Fund's management fee for the most recent fiscal year was in the third quintile relative to the management fees paid by other funds in its Morningstar peer group for the comparable period. The Trustees considered that the expense ratio of the Fund's Class A shares for the most recent fiscal year was in the third quintile relative to its Morningstar peer group and in the first quintile relative its Strategic Insight peer group, in each case for the comparable period. The Trustees noted that PIM was waiving fees and/or reimbursing expenses in order to limit the ordinary operating expenses of the Fund. The Trustees considered the impact of transfer agency, sub-transfer agency, and other non-management fee expenses on the expense ratios of the Fund. The Trustees noted that they separately review the Fund's transfer agency, sub-transfer agency and intermediary arrangements. The Trustees reviewed management fees charged by Pioneer to institutional and other clients, including publicly offered European funds sponsored by affiliates of Pioneer, unaffiliated U.S. registered investment companies (in a sub-advisory capacity), and unaffiliated foreign and domestic separate accounts. The Trustees also considered PIM's costs in providing services to the Fund and Pioneer's costs in providing services to the other clients and considered the differences in management fees and profit margins for Fund and non-Fund services. In evaluating the fees associated with Pioneer's client accounts, the Trustees took into account the respective demands, resources and complexity associated with the Fund and client accounts. The Trustees noted that, in some instances, the fee rates for those clients were lower than the management fee for the Fund and considered that, under the investment advisory agreement with the Fund, PIM performs additional services for the Fund that it does not provide to those other clients or services that are broader in scope, including oversight of the Fund's other service providers and activities related to compliance and the extensive regulatory and tax regimes to which the Fund is subject. The Trustees also considered the different entrepreneurial risks associated with PIM's management of the Fund and Pioneer's management of the other client accounts. Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 65 The Trustees concluded that the management fee payable by the Fund to PIM was reasonable in relation to the nature and quality of the services provided by PIM to the Fund. Profitability The Trustees considered information provided by PIM regarding the profitability of PIM with respect to the advisory services provided by PIM to the Fund, including the methodology used by PIM in allocating certain of its costs to the management of the Fund. The Trustees also considered PIM's profit margin in connection with the overall operation of the Fund. They further reviewed the financial results realized by PIM and its affiliates from non-fund businesses. The Trustees considered PIM's profit margins with respect to the Fund in comparison to the limited industry data available and noted that the profitability of any adviser was affected by numerous factors, including its organizational structure and method for allocating expenses. The Trustees concluded that PIM's profitability with respect to the management of the Fund was not unreasonable. Economies of Scale The Trustees considered PIM's views relating to economies of scale in connection with the Pioneer Funds as fund assets grow and the extent to which any such economies of scale are shared with funds and fund shareholders. The Trustees recognize that economies of scale are difficult to identify and quantify, and that, among other factors that may be relevant, are the following: fee levels, expense subsidization, investment by PIM in research and analytical capabilities and PIM's commitment and resource allocation to the Fund. The Trustees noted that profitability also may be an indicator of the availability of any economies of scale, although profitability may vary for other reasons including reductions in expenses. The Trustees concluded that economies of scale, if any, were being appropriately shared with the Funds. Other Benefits The Trustees considered the other benefits to PIM from its relationship with the Fund. The Trustees considered the character and amount of fees paid by the Fund, other than under the investment advisory agreement, for services provided by PIM and its affiliates. The Trustees further considered the revenues and profitability of PIM's businesses other than the fund business. Pioneer is the principal U.S. asset management business of Pioneer Global Asset Management, the worldwide asset management business of UniCredit Group, which manages over $150 billion in assets (including the Funds). Pioneer and the Funds receive reciprocal intangible benefits from the relationship, including mutual brand recognition and, for the Funds, direct 66 Pioneer Global Multisector Income Fund | Annual Report | 10/31/15 and indirect access to the resources of a large global asset manager. The Trustees concluded that any such benefits received by Pioneer as a result of its relationship with the Funds were reasonable and their consideration of the advisory agreement between the Fund and PIM and the fees thereunder were unaffected by Pioneer's possible receipt of any such intangible benefits. Conclusion After consideration of the factors described above as well as other factors, the Trustees, including all of the Independent Trustees, concluded that the investment advisory agreement between PIM and the Fund, including the fees payable thereunder, was fair and reasonable and voted to approve the proposed renewal of the investment advisory agreement for the Fund.

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.
