Consumer incomes, savings, wealth, and debt-servicing capacity have been solid buttresses for the recovering housing and auto industries. Industrial activity is growing only moderately, but current corporate profits are generally solid and balance sheets appear able to support needed capital spending and dividend* payouts. A modestly improving European economy and continuing economic improvement in Japan appear likely to result in improving global growth in 2014, further supporting the U.S. economy. In addition, we feel that continuing slack in labor markets and capacity utilization offer the potential for continuing growth without bottlenecks and rising inflation. After observing the strengthening economic trends, the Federal Reserve System (the Fed) has begun scaling back its QE (quantitative easing) program, but short-term interest rates remain near zero, and while Fed Chair Janet Yellen has suggested that rates may be raised roughly six months after the QE program is fully tapered, that would still place the potential rate hike sometime in 2015. There are certainly risks and uncertainties still facing the global economy as 2014 moves along. The European economy, while improving, remains weak, the Japanese economy faced a tax hike this spring, and a number of emerging market countries are experiencing difficulties. There are also geopolitical worries abroad, such as Russia's aggressive move against the Ukraine, and more potential political fights at home, especially during a mid-term election year. While most of the widely recognized risks we have outlined may already be "priced into" the market, we believe investors should continue to expect market volatility. At Pioneer, we have long advocated the benefits of staying diversified and investing for the long term. And while diversification does not assure a profit or protect against loss in a declining market, we believe there are still opportunities for prudent investors to earn attractive returns. Our advice, as always, is to work closely with a trusted financial advisor to discuss your goals and work together to develop an investment strategy that meets your individual needs, keeping in mind that there is no single best strategy that works for every investor. * Dividends are not guaranteed. 2 Pioneer Emerging Markets Local Currency Debt Fund | Semiannual Report | 4/30/14 Pioneer's investment teams have, since 1928, sought out attractive opportunities in equity and bond markets, using in-depth research to identify undervalued individual securities, and using thoughtful risk management to construct portfolios which seek to balance potential risks and rewards in an ever-changing world.

Pioneer Emerging Markets Local Currency Debt Fund | Semiannual Report | 4/30/14 3 Portfolio Management Discussion | 4/30/14 In the following discussion, portfolio managers Hakan Aksoy and Esther Law review recent market events and describe the factors that affected the performance of Pioneer Emerging Markets Local Currency Debt Fund during the six-month period ended April 30, 2014. Mr. Aksoy and Ms. Law, both portfolio managers at Pioneer, are responsible for the day-to-day management of the Fund. Q How did emerging markets bonds and currencies perform during the six-month period ended April 30, 2014? A Local currency emerging markets bonds finished the six-month period with a negative return, due largely to their poor performance from November 2013 through January 2014. The downturn was fueled by concerns about the potential impact of the U.S. Federal Reserve's (the Fed's) decision to "taper" its quantitative easing (QE) policy as well as slowing growth in key emerging economies. The prospect of higher bond yields in the United States drew cash out of the emerging markets, leading to weakness in bond markets and fueling substantial sell-offs in certain emerging currencies. January 2014, in particular, saw a sharp downturn in the currency markets, leading to meaningful underperformance for local currency debt in the first month of the year. The markets stabilized and began to move higher from February 2014 onward, as investors gradually became used to the idea of the Fed's tapering of QE. Emerging markets bonds, following their weakness over the previous nine months, offered relatively attractive yields that enticed a broader range of investors once risk appetites began to recover. Despite their February to April 2014 rebound, local currency bonds trailed their U.S. dollar- denominated counterparts for the full six-month period ended April 30, 2014. While local currency debt underperformed in the short term, we continue to have a positive long-term view on the asset class based on the higher yields, diversification benefits, and longer-term appreciation potential we believe local currency debt offers. Q How did the Fund perform during the six-month period ended April 30, 2014? A Pioneer Emerging Markets Local Currency Debt Fund's Class A shares returned -1.65% at net asset value during the six-month period ended April 30, 2014, while the Fund's benchmark, the JP Morgan Government 4 Pioneer Emerging Markets Local Currency Debt Fund | Semiannual Report | 4/30/14 Bond Index-Emerging Markets Global Diversified Index (the JP Morgan Index), returned -1.48%. During the same period, the average return of the 104 mutual funds in Lipper's Emerging Markets Local Currency Debt Funds category was -1.58% and the average return of the 353 mutual funds in Morningstar's Emerging Markets Bond Funds category was 0.71%. Q What investment decisions played the biggest roles in the Fund's benchmark- relative performance during the six-month period ended April 30, 2014, both from a positive and negative standpoint? A Two aspects of the Fund's positioning stood out for their positive contributions to relative performance during the period. First, the portfolio's duration was below that of the JP Morgan Index benchmark. (Duration is a measure of a portfolio's price-sensitivity to changes in interest rates). Anticipating volatility in U.S. Treasuries, we sought to reduce the Fund's interest-rate exposure by holding shorter-duration bonds where appropriate. In addition, we allocated a substantial portion of the portfolio's assets to corporate bonds. Since corporate bonds in the emerging markets typically have a lower duration than government debt, this also helped to reduce the Fund's interest-rate sensitivity during the period. Further, corporate bonds generally offer higher yields than government issues, yet in many cases the underlying financial strength of corporations is as good - or better - than that of governments. The Fund's weighting in corporate bonds as of April 30, 2014, was approximately 40% of total investment portfolio, reflecting our view that the corporate segment of the market offers a meaningful long-term opportunity. The second helpful aspect of our investment approach during the period was the Fund's defensive positioning. We believed a defensive strategy was appropriate given the risks in the global economy. The defensive posture of the portfolio aided Fund performance given the volatility that occurred in the first half of the six-month period. It should be noted, however, that the defensive strategy detracted from performance to a certain degree once the market began to recover. Nevertheless, we believe that the most effective way to generate positive Fund performance over time is through country allocations and individual security research, and not by attempting to boost returns by taking on excess portfolio risk. By far the biggest detractor from the Fund's performance relative to the benchmark during the period came from country allocations. In particular, the portfolio's positions in Russia, South Africa, and Turkey hurt the Fund's relative performance. Pioneer Emerging Markets Local Currency Debt Fund | Semiannual Report | 4/30/14 5 Q How was the Fund's portfolio positioned as of April 30, 2014? A We employ an active investment approach that seeks to capitalize on value opportunities and avoid market segments with a less attractive risk/return profiles. We are currently finding the most compelling investments in Latin America. While the region's economies aren't as efficient as those in other parts of the world, there is also a lower risk of political disruptions. We believe the relative political stability provides the latitude for performance upside if the region's economies do indeed become more efficient in the years ahead. Mexico represents the portfolio's largest overweight in Latin America, as the country is enacting meaningful reforms and its economy is supported by a strong trading relationship with the United States. We also have a portfolio tilt toward Peru, which has substantial foreign-currency reserves, and Colombia, which has a stable economy and is benefiting from inflows stemming from its increased weighting within certain key benchmark indices. The Fund has a neutral-weight in Brazil. While Brazil's slowing economic growth represents a headwind for the country's bond market, that factor is offset to some extent by the attractive yields on its local-currency debt. In the Europe/Middle East/Africa (EMEA) region, several aspects of the Fund's positioning deviate from the JP Morgan Index and industry peer groups. For instance, the Fund is underweight in Russia, and the Russian bonds the portfolio does own are of shorter duration. Russia's slowing economic growth made us cautious about the country even before the Ukrainian conflict became a factor, and now the growth outlook is even murkier due to the possibility of international sanctions. The Fund is overweight in Poland, where the bond market has been supported by rising exports and a healthy domestic economy. The Fund is underweight in Hungary, where yields are too low to offset the potential currency risk, and slightly overweight in Nigeria, which offers attractive, low double-digit yields and - in contrast to other countries within EMEA - has minimal exposure to the problems in the Ukraine. The Fund holds a neutral position in South Africa and Turkey. While Turkey offers attractive yields and a favorable growth outlook, we believe the country's upcoming elections will lead to elevated volatility in its financial markets. India, which is not represented in the JP Morgan Index benchmark, is the portfolio's top country pick within Asia. We believe this year's elections will bring about positive change, and we think the country's central bank will adopt favorable, growth-oriented policies under the direction of its new governor, Raghuram Rajan. We also like Indonesia, which has a positive growth outlook and a favorable trade-off of risk and return potential. 6 Pioneer Emerging Markets Local Currency Debt Fund | Semiannual Report | 4/30/14 Q What is your outlook for emerging markets debt? A We hold a cautiously optimistic outlook for emerging markets bonds for the remainder of 2014. Economic growth in the emerging markets is slowing from an average of about 5% in 2012 to the 4% to 4.5% range, but the pace remains well above that of the developed markets. Such growth rates should attract assets from lower-yielding countries over time, which is a positive for the supply-and-demand equation. As noted earlier, investors also have become more comfortable with the idea of Fed's tapering of its QE program, meaning that the market impact of the issue is now largely in the rear-view mirror. Having said this, we also expect that volatility in the emerging debt markets will remain high. U.S. Treasury yields declined over the first four months of 2014, but over the longer term, we expect that the 10-year Treasury yield will move above the 3% level. In addition, we expect that the cycle of interest-rate increases in the emerging markets still has a bit further to run. That translates to a higher cost of funding for emerging markets countries, which increases the odds of periodic disruptions like the one that occurred during January 2014. Geopolitical issues, such as the conflict in the Ukraine, also represent a potential headwind to performance. Overall, however, we believe the emerging markets are on track for improved performance in 2014. An important element of support are the high yields available in the emerging markets relative to those available in the developed world, which not only attracts demand from yield-seeking investors, but also provides a favorable starting point for total return. Against this backdrop, we believe our diversified*, actively-managed, and long-term investment approach can continue to add value for the Fund's shareholders. Please refer to the Schedule of Investments on pages 16-20 for a full listing of Fund securities. Investing in foreign and/or emerging markets securities involves risks relating to interest rates, currency exchange rates, economic, and political conditions. The Fund is non-diversified, which means that it can invest a large percentage of its assets in the securities of any one or more issuers. This increases the Fund's potential risk exposure. * Diversification does not assure a profit nor protect against loss in a declining market. Pioneer Emerging Markets Local Currency Debt Fund | Semiannual Report | 4/30/14 7 To the extent the Fund invests in issuers located within specific countries or regions, the Fund may be particularly affected by adverse markets, rates, and events which may occur in those countries and regions. 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. 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. 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. At times, the Fund's investments may represent industries or sectors that are interrelated or have common risks, making them more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. 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. Past performance is no guarantee of future results, and there is no guarantee that market forecasts discussed will be realized.

Pioneer Emerging Markets Local Currency Debt Fund | Semiannual Report | 4/30/14 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 Emerging Markets Local Currency Debt Fund Based on actual returns from November 1, 2013, through April 30, 2014. --------------------------------------------------------------------------------------------------- Share Class A C Y --------------------------------------------------------------------------------------------------- Beginning Account Value on 11/1/13 $1,000.00 $1,000.00 $1,000.00 --------------------------------------------------------------------------------------------------- Ending Account Value (after expenses) $983.50 $979.70 $984.80 on 4/30/14 --------------------------------------------------------------------------------------------------- Expenses Paid During Period* $5.56 $9.13 $4.18 --------------------------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized net expense ratio of 1.13%, 1.86% and 0.85% for Class A, Class C and Class Y shares, respectively, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the partial year period). 14 Pioneer Emerging Markets Local Currency Debt Fund | Semiannual Report | 4/30/14 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.

Pioneer Emerging Markets Local Currency Debt Fund | Semiannual Report | 4/30/14 27 Notes to Financial Statements | 4/30/14 (unaudited) 1. Organization and Significant Accounting Policies Pioneer Emerging Markets Local Currency Debt Fund (the Fund) is a series of Pioneer Series Trust VII, a Delaware statutory trust. The Fund is registered under the Investment Company Act of 1940 as a non-diversified, open-end management investment company. The investment objective of the Fund is total return through a combination of income and capital appreciation. The Fund offers three classes of shares designated as Class A, Class C, and Class Y shares. Class A, Class C, and Class Y shares were first publicly offered on February 5, 2013. Each class of shares represents an interest in the same portfolio of investments of the Fund and has identical rights (based on relative net asset values) to assets and liquidation proceeds. Share classes can bear different rates of class-specific fees and expenses such as transfer agent and distribution fees. Differences in class-specific fees and expenses will result in differences in net investment income and, therefore, the payment of different dividends from net investment income earned by each class. The Amended and Restated Declaration of Trust of the Fund gives the Board the flexibility to specify either per-share voting or dollar-weighted voting when submitting matters for shareholder approval. Under per-share voting, each share of a class of the Fund is entitled to one vote. Under dollar-weighted voting, a shareholder's voting power is determined not by the number of shares owned, but by the dollar value of the shares on the record date. Each share class has exclusive voting rights with respect to matters affecting only that class, including with respect to the distribution plan for that class. There is no distribution plan for Class Y shares. The Fund's financial statements have been prepared in conformity with U.S. generally accepted accounting principles that require the management of the Fund to, among other things, make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income, expenses and gain or loss on investments during the reporting period. Actual results could differ from those estimates. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements, which are consistent with those policies generally accepted in the investment company industry: 28 Pioneer Emerging Markets Local Currency Debt Fund | Semiannual Report | 4/30/14 A. Security Valuation Security transactions are recorded as of trade date. The net asset value of the Fund is computed once daily, on each day the New York Stock Exchange (NYSE) is open, as of the close of regular trading on the NYSE. Fixed income securities with remaining maturity of more than sixty days are valued at prices supplied by independent pricing services, which consider such factors as market prices, market events, quotations from one or more brokers, Treasury spreads, yields, maturities and ratings. Valuations may be supplemented by dealers and other sources, as required. Equity securities that have traded on an exchange are valued at the last sale price on the principal exchange where they are traded. Equity securities that have not traded on the date of valuation, or securities for which sale prices are not available, generally are valued using the mean between the last bid and asked prices. Short-term fixed income securities with remaining maturities of sixty days or less generally are valued at amortized cost. 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 for which independent pricing services are unable to supply prices or for which market prices and/or quotations are not readily available or are considered to be unreliable are valued 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 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. Pioneer Emerging Markets Local Currency Debt Fund | Semiannual Report | 4/30/14 29 At April 30, 2014, there were no securities that were valued using fair value methods (other than securities that were valued using prices supplied by independent pricing services or broker-dealers). Principal amounts of mortgage-backed securities are adjusted for monthly paydowns. Premiums and discounts related to certain mortgage-backed securities are amortized or accreted in proportion to the monthly paydowns. All discounts/premiums on debt securities are accreted/amortized for financial reporting purposes over the life of the respective securities, and such accretion/amortization is included in interest income. Dividend income is recorded on the ex-dividend date, except that certain dividends from foreign securities where the ex-dividend date may have passed are recorded as soon as the Fund becomes aware of the ex-dividend data in the exercise of reasonable diligence. Interest income, including interest on income bearing cash accounts, is recorded on the accrual basis. Dividend and interest income are reported net of unrecoverable foreign taxes withheld at the applicable country rates. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. B. Foreign Currency Translation The books and records of the Fund are maintained in U.S. dollars. Amounts denominated in foreign currencies are translated into U.S. dollars using current exchange rates. Net realized gains and losses on foreign currency transactions, if any, represent, among other things, the net realized gains and losses on foreign currency contracts, disposition of foreign currencies and the difference between the amount of income accrued and the U.S. dollars actually received. Further, the effects of changes in foreign currency exchange rates on investments are not segregated in the statement of operations from the effects of changes in the market prices of those securities but are included with the net realized and unrealized gain or loss on investments. C. Forward Foreign Currency Contracts The Fund may enter into forward foreign currency contracts (contracts) for the purchase or sale of a specific foreign currency at a fixed price on a future date. 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 30 Pioneer Emerging Markets Local Currency Debt Fund | Semiannual Report | 4/30/14 these contracts from the potential inability of counterparties to meet the terms of the contract and from unanticipated movements in the value of foreign currencies relative to the U.S. dollar. D. Federal Income Taxes It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income and net realized capital gains, if any, to its shareowners. Therefore, no federal income tax provision is required. As of April 30, 2014, the Fund did not accrue any interest or penalties with respect to unrecognized 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 are subject to examination by federal and state tax authorities. In addition to the requirements of the internal Revenue Code, the fund may also be required to pay local taxes on the recognition of capital gains and/or the repatriation of foreign currencies in certain countries. During the six months ended April 30, 2014, the Fund paid $55,063 in such taxes. In determining the daily net asset value, the Fund estimates the reserve for such taxes, if any, associated with investments in certain countries. The estimated reserve for the capital gains is based on the net unrealized appreciation on certain portfolio securities, the holding period of such securities and the related tax rates, tax loss carryforward (if applicable) and other such factors. As of April 30, 2014, the Fund had $2,637 in reserve related to capital gains. 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. The tax character of current year distributions payable will be determined at the end of the current taxable year. The tax character of distributions paid during the year ended October 31, 2013 was as follows: -------------------------------------------------------------------------------- 2013 -------------------------------------------------------------------------------- Distributions paid from: Ordinary income $210,841 Return of capital 63,730 -------------------------------------------------------------------------------- Total $274,571 ================================================================================ Pioneer Emerging Markets Local Currency Debt Fund | Semiannual Report | 4/30/14 31 The following shows the components of distributable earnings on a federal income tax basis at October 31, 2013: -------------------------------------------------------------------------------- 2013 -------------------------------------------------------------------------------- Distributable earnings: Capital loss carryforward $ (80,860) Dividend payable (46,150) Net unrealized depreciation (1,188,713) -------------------------------------------------------------------------------- Total $(1,315,723) ================================================================================ The difference between book-basis and tax-basis net unrealized depreciation is attributable to the tax deferral of losses on wash sales. E. Fund Shares The Fund records sales and repurchases of its shares as of trade date. Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the Fund and a wholly-owned indirect subsidiary of UniCredit S.p.A. (UniCredit), earned $36 in underwriting commissions on the sale of Class A shares during the during the six months ended April 30, 2014. F. Class Allocations Income, common expenses and realized and unrealized gains and losses are calculated at the Fund level and allocated daily to each class of shares based on its respective percentage of adjusted net assets at the beginning of the day. Distribution fees are calculated based on the average daily net asset value attributable to Class A and Class C shares of the Fund, respectively (see Note 4). Class Y shares do not pay distribution fees. All expenses and fees paid to the transfer agent, Pioneer Investment Management Shareholder Services, Inc. (PIMSS), for its services are allocated among the classes of shares based on the number of accounts in each class and the ratable allocation of related out-of-pocket expenses (see Note 3). The Fund declares as daily dividends substantially all of its net investment income. All dividends are paid on a monthly basis. Short-term capital gain distributions, if any, may be declared with the daily dividends. Distributions to shareowners are recorded as of the ex-dividend date. Distributions paid by the Fund with respect to each class of shares are calculated in the same manner and at the same time, except that net investment income dividends to Class A, Class C and Class Y shares can reflect different transfer agent and distribution expense rates. 32 Pioneer Emerging Markets Local Currency Debt Fund | Semiannual Report | 4/30/14 G. Risks At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making the Fund more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. The Fund's investments in foreign markets and countries with limited developing markets may subject the Fund to a greater degree of risk than 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. H. Interest Rate Swap Contracts The Fund may enter into interest rate swaps to attempt to hedge against interest rate fluctuations or to enhance its income. Pursuant to the interest rate swap agreement, the Fund negotiates with a counterparty to exchange a periodic stream of payments based on a benchmark interest rate. One cash flow stream will typically be a floating rate payment based upon the specified floating benchmark interest rate while the other is typically a fixed interest rate. Payment flows are usually netted against each other, with the difference being paid by one party to the other on a monthly basis. Periodic payments received or paid by the Fund are recorded as realized gains or losses in the Statement of Operations. Interest rate 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. Interest rate swap contracts are subject to counterparty risk and movements in interest rates. Open interest rate swap contracts at April 30, 2014 are listed in the Schedule of Investments. The average value of interest rate swap contracts open during the six months ended April 30, 2014 was $70,644. 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 0.70% of the Fund's average daily net assets up to $1 billion and 0.65% on assets over $1 billion. For the six months ended April 30, 2014, the effective management fee was equivalent to 0.70% 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 1.20%, 2.10% and 0.85% of the average daily net assets attributable to Class A, Class C and Class Y shares, respectively. Fees waived and expenses reimbursed during the six months Pioneer Emerging Markets Local Currency Debt Fund | Semiannual Report | 4/30/14 33 ended April 30, 2014 are reflected on the Statement of Operations. These expense limitations are in effect through March 1, 2015. There can be no assurance that PIM will extend the expense limitation agreement for a class of shares beyond the date referred to above. In addition, under the management and administration agreements, certain other services and costs, including accounting, regulatory reporting and insurance premiums, are paid by the Fund as administrative reimbursements. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $8,725 in management fees, administrative costs and certain other reimbursements payable to PIM at April 30, 2014. 3. Transfer Agent PIMSS, a wholly owned indirect subsidiary of UniCredit, provides substantially all transfer agent and shareowner services to the Fund at negotiated rates. In addition, the Fund reimburses PIMSS for out-of-pocket expenses incurred by PIMSS related to shareholder communications activities such as proxy and statement mailings, outgoing phone calls and omnibus relationship contracts. For the six months ended April 30, 2014, such out-of-pocket expenses by class of shares were as follows: -------------------------------------------------------------------------------- Shareholder Communications: -------------------------------------------------------------------------------- Class A $256 Class C 72 Class Y 9 -------------------------------------------------------------------------------- Total $337 ================================================================================ Included in "Due from affiliates" reflected on the Statement of Assets and Liabilities is $125 in transfer agent fees and out-of-pocket reimbursements payable from PIMSS at April 30, 2014. 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 34 Pioneer Emerging Markets Local Currency Debt Fund | Semiannual Report | 4/30/14 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 distribution services with regard to Class C shares. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $302 in distribution fees payable to PFD at April 30, 2014. 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 purchases 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 six months ended April 30, 2014, no CDSCs were paid to PFD. 5. Expense Offset Arrangements The Fund has 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 six months ended April 30, 2014, the Fund's expenses were not reduced under such arrangements. 6. Additional Disclosures about Derivative Instruments and Hedging Activities Values of derivative instruments as of April 30, 2014 were as follows: --------------------------------------------------------------------------------------------- Derivatives Not Accounted for as Asset Derivatives 2014 Liabilities Derivatives 2014 Hedging Instruments --------------------------------------------------------------- Under Accounting Statement of Assets Statement of Assets Standards Codification and Liabilities and Liabilities (ASC) 815 Location Value Location Value --------------------------------------------------------------------------------------------- Interest Rate Swaps Net unrealized Net unrealized appreciation on depreciation on interest rate interest rate swaps $437 swaps $-- --------------------------------------------------------------------------------------------- Total $437 $-- --------------------------------------------------------------------------------------------- Pioneer Emerging Markets Local Currency Debt Fund | Semiannual Report | 4/30/14 35 The effect of derivative instruments on the Statement of Operations for the six months ended April 30, 2014 was as follows: --------------------------------------------------------------------------------------------------- Change in Derivatives Not Unrealized Accounted for as Realized appreciation or Hedging Instruments Gain on (depreciation) Under Accounting Location of Gain or (Loss) Derivatives on Derivatives Standards Codification on Derivatives Recognized Recognized Recognized (ASC) 815 in Income in Income in Income --------------------------------------------------------------------------------------------------- Interest Rate Swaps Net realized gain on interest rate swaps $-- Interest Rate Swaps Change in unrealized appreciation on interest rate swaps $437 9.

Subsequent Events Change in Independent Registered Public Accounting Firm The Board of Trustees of the Fund, with the approval and recommendation of the Audit Committee, appointed Deloitte & Touche LLP to serve as the Fund's independent registered public accounting firm for the fiscal year ending October 31, 2014. Deloitte & Touche LLP replaces Ernst & Young LLP, which resigned as the Fund's independent registered public accounting firm, effective upon completion of the audit of the Fund's financial statements for the fiscal year ended October 31, 2013. During the periods that Ernst & Young LLP served as the Fund's independent registered public accounting firm, including the Fund's two most recent fiscal year, Ernst & Young LLP's reports on the financial statements of the Fund have not contained an adverse opinion or disclaimer of opinion and have not been qualified or modified as to uncertainty, audit scope or accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which, if not resolved to the satisfaction of Ernst & Young LLP would have caused Ernst & Young LLP to make reference to the subject matter of the disagreement in connection with its report on the financial statements. In addition, there have been no reportable events to the kind described in Item 304(a)(i)(v)of Regulation S-K under the Securities and Exchange Act of 1934. Pioneer Emerging Markets Local Currency Debt Fund | Semiannual Report | 4/30/14 37 Approval of Investment Advisory Agreement Pioneer Investment Management, Inc. (PIM) serves as the investment adviser to Pioneer Emerging Markets Local Currency Debt 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 March 2013 as the Trustees of the Fund agreed on, among other things, an overall approach and timeline for the process. In July 2013, the Trustees approved the format of the contract review materials and submitted their formal request to PIM to furnish information necessary to evaluate the terms of the investment advisory agreement. The contract review materials were provided to the Trustees in July 2013 and September 2013. After reviewing and discussing the materials, the Trustees submitted a request for additional information to PIM, and materials were provided in response to this request. Meetings of the Independent Trustees of the Fund were held in July, September, and November, 2013 to review and discuss the contract review materials. In addition, the Trustees took into account the information related to the Fund provided to the Trustees at regularly scheduled meetings. At a meeting held on November 12, 2013, 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 considering the renewal of the investment advisory agreement, the Trustees considered various factors that they determined were relevant, including the factors described below. In all quintile rankings referred to throughout this disclosure, first quintile is most favorable to the Fund's shareowners. Thus, highest relative performance would be first quintile and lowest relative expenses would also be first quintile. The Trustees 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 reviewed the terms of the investment advisory agreement. The Trustees also reviewed PIM's investment approach for the Fund and its research process. The Trustees considered the resources of PIM and the personnel of PIM who provide investment management services to the Fund. They also reviewed the amount of 38 Pioneer Emerging Markets Local Currency Debt Fund | Semiannual Report | 4/30/14 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 The Trustees review the Fund's performance on a regular basis, based on analysis and data prepared by PIM for this purpose and discuss performance issues with PIM on an ongoing basis. The Trustees noted the discussions held throughout the year regarding the Fund's performance and confirmed that those discussions were factored into the Trustees' deliberations concerning the renewal of the advisory agreement. It was noted that the Fund commenced operations in 2013 and had a performance history of less than one year at the time the Trustees considered the renewal of the investment advisory agreement. The Trustees concluded that the investment performance of the Fund was satisfactory. Management Fee and Expenses The Fund commenced operations in 2013 and had an operating history of less than one year at the time the Trustees considered the renewal of the investment advisory agreement. Accordingly, the Trustees took into account information provided in connection with the initial approval of the investment advisory agreement. The Trustees considered information compiled by Strategic Insight Simfund, an independent third party, to compare the Fund's proposed management fee and anticipated expense ratio with a peer group of funds included in the Morningstar Emerging Markets Bond category. The Trustees considered that the Fund's management fee would rank in the second quintile of the peer group. The Trustees also considered that, taking into account the contractual expense limitation agreed to by PIM with respect to the Fund, the Fund's expense ratio would rank in Pioneer Emerging Markets Local Currency Debt Fund | Semiannual Report | 4/30/14 39 the third quintile of the peer group. The Trustees concluded that the management fee payable by the Fund to PIM was reasonable in relation to the nature and quality of services to be provided by PIM. The Trustees reviewed management fees charged by PIM and PIM's affiliate, Pioneer Institutional Asset Management, Inc. (together with PIM, "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. 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. Profitability The Fund commenced operations in 2013 and had an operating history of less than one year at the time the Trustees considered the renewal of the investment advisory agreement. Accordingly, the Trustees did not consider PIM's profitability with respect to the management of the Fund in approving the renewal of the investment advisory agreement. 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 breakpoint in the management fee schedule. The Trustees recognize that economies of scale are difficult to identify and quantify, rarely identifiable on a Fund-by-Fund basis, and that, among other factors that may be relevant, are the following: fee levels, expense 40 Pioneer Emerging Markets Local Currency Debt Fund | Semiannual Report | 4/30/14 subsidization, investment by PIM in research and analytical capabilities and PIM's commitment and resource allocation to the Funds. 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 particularly, for example during the recent difficult periods for financial markets, as the level of services was maintained notwithstanding a significant decline in PIM's fee revenues from the Funds. Accordingly, the Trustees concluded that economies of scale, if any, were being appropriately shared with the Fund. 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. The Trustees considered the intangible benefits to PIM by virtue of its relationship with the Fund and the other Pioneer funds. The Trustees concluded that the receipt of these benefits was reasonable in the context of the overall relationship between PIM and the Fund. Conclusion After consideration of the factors described above as well as other factors, the Trustees, including all of the Independent Trustees, concluded that the 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.

Consumer incomes, savings, wealth, and debt-servicing capacity have been solid buttresses for the recovering housing and auto industries. Industrial activity is growing only moderately, but current corporate profits are generally solid and balance sheets appear able to support needed capital spending and dividend* payouts. A modestly improving European economy and continuing economic improvement in Japan appear likely to result in improving global growth in 2014, further supporting the U.S. economy. In addition, we feel that continuing slack in labor markets and capacity utilization offer the potential for continuing growth without bottlenecks and rising inflation. After observing the strengthening economic trends, the Federal Reserve System (the Fed) has begun scaling back its QE (quantitative easing) program, but short-term interest rates remain near zero, and while Fed Chair Janet Yellen has suggested that rates may be raised roughly six months after the QE program is fully tapered, that would still place the potential rate hike sometime in 2015. There are certainly risks and uncertainties still facing the global economy as 2014 moves along. The European economy, while improving, remains weak, the Japanese economy faced a tax hike this spring, and a number of emerging market countries are experiencing difficulties. There are also geopolitical worries abroad, such as Russia's aggressive move against the Ukraine, and more potential political fights at home, especially during a mid-term election year. While most of the widely recognized risks we have outlined may already be "priced into" the market, we believe investors should continue to expect market volatility. At Pioneer, we have long advocated the benefits of staying diversified and investing for the long term. And while diversification does not assure a profit or protect against loss in a declining market, we believe there are still opportunities for prudent investors to earn attractive returns. Our advice, as always, is to work closely with a trusted financial advisor to discuss your goals and work together to develop an investment strategy that meets your individual needs, keeping in mind that there is no single best strategy that works for every investor. * Dividends are not guaranteed. 2 Pioneer Global High Yield Fund | Semiannual Report | 4/30/14 Pioneer's investment teams have, since 1928, sought out attractive opportunities in equity and bond markets, using in-depth research to identify undervalued individual securities, and using thoughtful risk management to construct portfolios which seek to balance potential risks and rewards in an ever-changing world.

Pioneer Global High Yield Fund | Semiannual Report | 4/30/14 3 Portfolio Management Discussion | 4/30/14 The environment for global high-yield corporate bond investing appeared to improve and stabilize during the six-month period ended April 30, 2014, as the U.S. economy continued to grow at a moderate pace, the European economy emerged from recession, and many emerging markets were able to recover from earlier volatility. In the following interview, Andrew Feltus discusses the market environment and the performance of Pioneer Global High Yield Fund during the six-month period. Mr. Feltus, a senior vice president and portfolio manager at Pioneer, is lead manager of the Fund, and Tracy 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 six-month period ended April 30, 2014? A Pioneer Global High Yield Fund's Class A shares returned 3.67% at net asset value during the six-month period ended April 30, 2014, while the Fund's benchmarks, the Bank of America Merrill Lynch (BofA ML) Global High Yield and Emerging Markets Plus (GHY and EMP) Index, the BofA ML High Yield Master II Index, and the Barclays Global High Yield Index, returned 5.01%, 4.76%, and 5.35%, respectively*. During the same period, the average return of the 609 mutual funds in Lipper's High Current Yield Funds category was 4.09%, and the average return of the 700 mutual funds in Morningstar's High Yield Bond Funds category was 4.12%. Q How would you describe the investment environment for high-yield investors during the six-month period ended April 30, 2014? A The six-month period was a good one, in general, for high-yield investors, although the period began last November with a great deal of market volatility. Much of the volatility was the product of partisan political wrangling in Washington over economic policy issues that had resulted in a partial government shutdown in October 2013, just before the beginning of the six-month period. Topics ranging from raising the national debt ceiling to how much money should be approved to fund the overall Federal budget were among the most hotly debated. Emerging from the political squabbling, however, were a series of bipartisan agreements at the end of 2013 that at least temporarily settled the policy disputes and reassured the capital markets that the U.S. government would continue functioning and * Note to Shareholders: Effective October 31, 2013, the Barclays Global High Yield Index replaced the BofA ML GHY and EMP Index as a benchmark for the Fund. The BofA High Yield Master II Index remains as one of the Fund's benchmarks. For comparison purposes, Pioneer has continued to report returns for the BofA ML GHY and EMP Index for two full reporting cycles, including this April 30, 2014, semiannual report. This will be the final report in which returns for the BofA ML GHY and EMP Index will be provided. 4 Pioneer Global High Yield Fund | Semiannual Report | 4/30/14 paying its debts. Meanwhile, the U.S. economy appeared to be gaining strength, even if growth rates were not as high as many hoped. Corporate profits continued to improve, and default rates on corporate debt remained very low by historical standards. Signs of economic progress encouraged increased investment in so-called "risky" assets, including corporate bonds and stocks. Globally, investors also took encouragement from surprising economic strength in Europe as well as signs of recovery in many emerging economies--the fundamentals of which had previously been called into question over concerns that any monetary policy tightening by the U.S. Federal Reserve (the Fed) could adversely affect inflows of investment money to developing nations with large current account deficits. Recoveries were less evident in other commodity-exporting markets, however, mainly due to evidence of continued economic slowing in China, which affected demand for copper, iron, and other materials. Overall, though, the emerging markets appeared to be on stronger and more stable footing at the end of the six-month period than at the beginning of it. Geopolitical risks tended to temper market optimism during the period. While fears during the early part of the period that American military forces might be drawn into battle over control of Syria eventually subsided, new worries emerged in the late winter of 2014 over political tensions in the Ukraine and neighboring Russia's aggressive actions against that country. Even through all these crosscurrents, the riskier sectors of the capital markets remained in demand during the six-month period, with the prices of both stocks and high-yield bonds climbing. Default rates on high-yield and other economically-sensitive fixed-income debt securities remained low, while yield spreads tightened between higher-credit risk and lower-credit risk securities. (Spreads are commonly defined as the differences in yield between Treasuries and other types of fixed-income securities with similar maturities.) Q How did you position the Fund during the six-month period ended April 30, 2014, and which of your investment strategies had the biggest effects on the Fund's performance? A Benchmark-relative performance was held back by the Fund's underweighted positioning in Europe, and in particular by the portfolio's relatively weak exposures to both the euro and the British pound currencies. We did not have confidence in Europe's economic growth prospects, especially in the southern euro zone's peripheral nations such as Greece, Spain, Portugal and Italy. Economies on the continent appeared to rebound with surprising strength, however, while both the euro and the British pound gained in value against the U.S. dollar. Pioneer Global High Yield Fund | Semiannual Report | 4/30/14 5 The Fund's performance benefited from good security selection in both the United States and in the emerging markets during the period, while a portfolio underweight to the emerging markets overall also aided results. The Fund's exposure to U.S. high-yield corporate bonds also helped to boost results for the six-month period, with securities issued by industrial corporations faring particularly well. In the emerging markets, we focused the portfolio's investments on corporate bonds, emphasizing higher-yielding securities issued by financially strong companies. We generally avoided investing in sovereign government debt within the emerging markets. With that said, the Fund's results in the emerging markets were held back by portfolio exposures to both Russia and the Ukraine. Although we emphasized having the portfolio own corporate bonds rather than sovereign debt in both countries, the rising political tensions in the region affected the performance of corporate bonds as well as the currencies in which they were denominated. At the end of the six-month period, on April 30, 2014, the largest allocation in the Fund's portfolio remained U.S. high-yield corporate bonds, which accounted for nearly 32% of total invested assets. Corporate bonds in the emerging markets represented the portfolio's second-largest allocation, at nearly 26% of total investment portfolio, while emerging markets sovereign debt accounted for approximately 7% of total investment portfolio. Other noteworthy allocations in the Fund's portfolio as of period end included international high-yield corporate bonds (roughly 10% of total investment portfolio), convertible bonds (nearly 6%), floating-rate bank loans (just over 5%), and event-linked (catastrophe) bonds issued by insurance companies. Q What were some of the individual portfolio investments that affected the Fund's performance during the six-month period ended April 30, 2014? A One of the stronger positive contributions to Fund performance during the period came from the portfolio's investment in high-yield corporate bonds issued by Stanadyne, a U.S. manufacturer of engine parts. Stanadyne's bonds rose in value over the six-month period as the company sold some assets and reduced its overall debt. Bonds of Marfrig and Minerva, two Brazilian beef companies, also performed well for the Fund over the period, as did some inflation-linked bonds issued by the Mexican government. On the negative side, portfolio investments that underperformed during the period included the debt of Midwest Vanadium, an Australian mining company whose performance suffered after production was stopped due to a fire, and the convertible bonds of Cobalt Energy, a U.S.-based energy exploration-and-production company that experienced disappointing results from some drilling operations. 6 Pioneer Global High Yield Fund | Semiannual Report | 4/30/14 Q Was the Fund's performance affected by any exposure to derivative securities during the six-month period ended April 30, 2014? A We did use currency forward contracts - which are a type of derivative - to attempt to reduce the risks to the Fund from any volatility in world currency markets, as many investments are denominated in non-U.S. dollar currencies. However, the currency contracts that we used to hedge the portfolio's exposure to Europe detracted from Fund performance when the euro gained in value against the U.S. dollar. Q What is your investment outlook? A We expect that the expansion of the U.S. economy should continue at a steady pace, helped by both the Fed's continued relaxed monetary policies and evidence of strengthening in the industrial sector. Job growth has been steady, and consistent with the growth rates of previous expansions, while U.S. consumers are in far better financial shape than they were in 2008, having reduced much of their personal indebtedness. Both the housing and stock markets have bounced back well, and corporate profits have continued to rise. The corporate earnings outlook remains solid, and that should keep corporate bond default rates low. Despite those favorable factors, however, it is important to remember that corporate bond prices have increased noticeably, thus making their yield advantages over other fixed-income investments tighter and less pronounced. As a result, high-yield bonds now offer less margin of error should any problems arise. While Europe's economy offered many positive surprises over the past few months, strengthening more than was generally expected, we remain cautious about investing on the continent, as banking institutions in the region have not corrected all of their problems, and some countries with higher debt levels still could face issues in the future. Although we increased the Fund's exposure to the emerging markets during the past six months, we remain cautious and have maintained the portfolio's underweight position. Prices of high-yield emerging markets bonds are currently in line with long-term averages and still appear attractive relative to prices in the U.S. and in Europe, although the risks are higher. Slowing economic growth trends in China could have a huge effect on the emerging economies that are dependent upon exporting commodities such as iron, copper and coal. Upcoming major elections in nations such as Brazil and the Ukraine also could affect investment opportunities in the emerging markets. We continue to see investment opportunities in higher-yielding debt issued by financially sound companies, but we expect to remain cautious and highly selective when investing the Fund's assets, relying heavily on intensive security analysis of the debt instruments issued by individual companies. Pioneer Global High Yield Fund | Semiannual Report | 4/30/14 7 Please refer to the Schedule of Investments on pages 18-52 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, 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. Past performance is no guarantee of future results, and there is no guarantee that market forecasts discussed will be realized.

Pioneer Global High Yield Fund | Semiannual Report | 4/30/14 15 Comparing Ongoing Fund Expenses As a shareowner in the Fund, you incur two types of costs: (1) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses; and (2) transaction costs, including sales charges (loads) on purchase payments. This example is intended to help you understand your ongoing expenses (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 at the beginning of the Fund's latest six-month period and held throughout the six months. Using the Tables -------------------------------------------------------------------------------- Actual Expenses The first table below provides information about actual account values and actual expenses. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period as follows: (1) Divide your account value by $1,000 Example: an $8,600 account value (divided by) $1,000 = 8.6 (2) Multiply the result in (1) above by the corresponding share class's number in the third row under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Expenses Paid on a $1,000 Investment in Pioneer Global High Yield Fund Based on actual returns from November 1, 2013, through April 30, 2014. -------------------------------------------------------------------------------- Share Class A B C Y Z -------------------------------------------------------------------------------- Beginning Account $1,000.00 $1,000.00 $1,000.00 $1,000.00 $1,000.00 Value on 11/1/13 -------------------------------------------------------------------------------- Ending Account $1,036.70 $1,032.20 $1,033.10 $1,038.20 $1,037.70 Value (after expenses) on 4/30/14 -------------------------------------------------------------------------------- Expenses Paid $ 5.71 $ 9.88 $ 9.28 $ 4.30 $ 4.55 During Period* -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.13%, 1.96%, 1.84%, 0.85%, and 0.90% for Class A, Class B, Class C, Class Y and Class Z shares, respectively, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period). 16 Pioneer Global High Yield Fund | Semiannual Report | 4/30/14 Hypothetical Example for Comparison Purposes The table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads) that are charged at the time of the transaction. Therefore, the table below is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher.

The accompanying notes are an integral part of these financial statements. Pioneer Global High Yield Fund | Semiannual Report | 4/30/14 61 Notes to Financial Statements | 4/30/14 (Consolidated) (unaudited) 1. Organization and Significant Accounting Policies Pioneer Global High Yield Fund (the Fund) is a series of Pioneer Series Trust VII, a Delaware statutory trust. The Fund is registered under the Investment Company Act of 1940 as a diversified, open-end management investment company. The investment objective of the Fund is to maximize total return through a combination of income and capital appreciation. The Fund offers five classes of shares designated as Class A, Class B, Class C, Class Y and Class Z shares. Class Y shares were first publicly offered on December 28, 2005. Class Z shares were first publicly offered on July 6, 2007. Effective as of the close of business on December 31, 2009, Class B shares are no longer offered to new or existing shareholders, except that dividends and/or capital gain distributions may continue to be reinvested in Class B shares, and shareholders may exchange their Class B shares for Class B shares of other Pioneer funds, as permitted by existing exchange privileges. Each class of shares represents an interest in the same portfolio of investments of the Fund and has identical rights (based on relative net asset values) to assets and liquidation proceeds. Share classes can bear different rates of class-specific fees and expenses such as transfer agent and distribution fees. Differences in class-specific fees and expenses will result in differences in net investment income and, therefore, the payment of different dividends from net investment income earned by each class. The Amended and Restated Declaration of Trust of the Fund gives the Board the flexibility to specify either per share voting or dollar-weighted voting when submitting matters for shareholder approval. Under per share voting, each share of a class of the Fund is entitled to one vote. Under dollar-weighted voting, a shareholder's voting power is determined not by the number of shares owned, but by the dollar value of the shares on the record date. Each share class has exclusive voting rights with respect to matters affecting only that class, including with respect to the distribution plan for that class. There is no distribution plan for Class Y shares or Class Z shares. Class B shares convert to Class A shares approximately eight years after the date of purchase. The Fund's financial statements have been prepared in conformity with U.S. generally accepted accounting principles that require the management of the Fund to, among other things, make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income, expenses and gain or loss on investments during the reporting year. Actual results could differ from those estimates. 62 Pioneer Global High Yield Fund | Semiannual Report | 4/30/14 The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements, which are consistent with those policies generally accepted in the investment company industry: A. Security Valuation Security transactions are recorded as of trade date. The net asset value of the Fund is computed once daily, on each day the New York Stock Exchange (NYSE) is open, as of the close of regular trading on the NYSE. Senior floating rate loan interests (senior loans) are valued in accordance with guidelines established by the Board of Trustees at the mean between the last available bid and asked prices from one or more brokers or dealers as obtained from Loan Pricing Corporation, an independent pricing service. 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. Fixed income securities with remaining maturity of more than sixty days are valued at prices supplied by independent pricing services, which consider such factors as market prices, market events, quotations from one or more brokers, Treasury spreads, yields, maturities and ratings. Valuations may be supplemented by dealers and other sources, as required. Credit default swaps are valued by an independent pricing service based upon valuation models incorporating default probabilities, estimated recovery rates, actual reported transactions, and other available market data. Equity securities that have traded on an exchange are valued at the last sale price on the principal exchange where they are traded. Equity securities that have not traded on the date of valuation, or securities for which sale prices are not available, generally are valued using the mean between the last bid and asked prices. Short-term fixed income securities with remaining maturities of sixty days or less generally are valued at amortized cost. Shares of money market mutual funds are valued at such funds' net asset value. Trading in foreign securities is substantially completed each day at various times prior to the close of the NYSE. The values of such securities used in computing the net asset value of the Fund's shares are determined as of such times. Securities or senior loan interests 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 Pioneer Global High Yield Fund | Semiannual Report | 4/30/14 63 team uses fair value methods approved by the Valuation Committee of the Board of Trustees. PIM's fair value 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 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 April 30, 2014, two securities were valued using fair value methods (in addition to securities valued using prices supplied by independent pricing services broker-dealers) representing 0.1% of net assets. Principal amounts of mortgage-backed securities are adjusted for monthly paydowns. Premiums and discounts related to certain mortgage-backed securities are amortized or accreted in proportion to the monthly paydowns. All discounts/premiums on debt securities are accreted/amortized for financial reporting purposes over the life of the respective securities, and such accretion/amortization is included in interest income. Dividend income is recorded on the ex-dividend date, except that certain dividends from foreign securities where the ex-dividend date may have passed are recorded as soon as the Fund becomes aware of the ex-dividend data in the exercise of reasonable diligence. Interest income, including interest on income bearing cash accounts, is recorded on the accrual basis, net of unrecoverable foreign taxes withheld at the applicable country rates. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. B. Foreign Currency Translation The books and records of the Fund are maintained in U.S. dollars. Amounts denominated in foreign currencies are translated into U.S. dollars using current exchange rates. 64 Pioneer Global High Yield Fund | Semiannual Report | 4/30/14 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. C. Forward Foreign Currency Contracts The Fund may enter into forward foreign currency contracts (contracts) for the purchase or sale of a specific foreign currency at a fixed price on a future date. All contracts are marked to market daily at the applicable exchange rates, and any resulting unrealized 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). D. Federal Income Taxes It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income and net realized capital gains, if any, to its shareowners. Therefore, no provision for federal income taxes is required. As of April 30, 2014, 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. Pioneer Global High Yield Fund | Semiannual Report | 4/30/14 65 The tax character of current year distributions payable will be determined at the end of the current taxable year. The tax character of distributions paid during the year ended October 31, 2013 was as follows: ---------------------------------------------------------------------------- 2013 ---------------------------------------------------------------------------- Distributions paid from: Ordinary income $133,745,876 ---------------------------------------------------------------------------- Total $133,745,876 ============================================================================ The following shows the components of distributable earnings on a federal income tax basis at October 31, 2013: ---------------------------------------------------------------------------- 2013 ---------------------------------------------------------------------------- Distributable earnings: Undistributed ordinary income $ 4,281,580 Capital loss carryforward (270,530,204) Current year dividend payable (1,370,221) Unrealized depreciation (72,626,530) ---------------------------------------------------------------------------- Total $ (340,245,375) ============================================================================ 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. E. Fund Shares The Fund records sales and repurchases of its shares as of trade date. Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the Fund and a wholly owned indirect subsidiary of UniCredit S.p.A. (UniCredit), earned $26,791 in underwriting commissions on the sale of Class A shares during the six months ended April 30, 2014. F. Class Allocations Income, common expenses and realized and unrealized gains and losses are calculated at the Fund level and allocated daily to each class of shares based on its respective percentage of adjusted net assets at the beginning of the day. Distribution fees are calculated based on the average daily net asset value attributable to Class A, Class B and Class C shares of the Fund, respectively (see Note 5). Class Y and Class Z shares do not pay distribution fees. All expenses and fees paid to the transfer agent, Pioneer Investment Management. Shareholder Services, Inc. (PIMSS), for its services are allocated among the classes of shares based on the number of accounts in each class and the ratable allocation of related out-of-pocket expenses (see Note 3). 66 Pioneer Global High Yield Fund | Semiannual Report | 4/30/14 The Fund declares as daily dividends substantially all of its net investment income. All dividends are paid on a monthly basis. Short-term capital gain distributions, if any, may be declared with the daily dividends. Distributions to shareowners are recorded as of the ex-dividend date. Distributions paid by the Fund with respect to each class of shares are calculated in the same manner and at the same time, except that net investment income dividends to Class A, Class B, Class C, Class Y and Class Z shares can reflect different transfer agent and distribution expense rates. G. Risks At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making the Fund more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. The Fund's investments in foreign markets and countries with limited developing markets may subject the Fund to a greater degree of risk than in a developed market. These risks include disruptive political or economic conditions and the imposition of adverse governmental laws or currency exchange restrictions. The Fund's prospectus contains unaudited information regarding the Fund's principal risks. Please refer to that document when considering the Fund's principal risks. The Fund invests in below investment grade (high yield) debt securities and preferred stocks. Some of these high yield securities may be convertible into equity securities of the issuer. Debt securities rated below investment grade are commonly referred to as "junk bonds" and are considered speculative. These securities involve greater risk of loss, are subject to greater price volatility, and are less liquid, especially during periods of economic uncertainty or change, than higher rated debt securities. H. Repurchase Agreements With respect to repurchase agreements entered into by the Fund, the value of the underlying securities (collateral), including accrued interest, is required to be equal to or in excess of the repurchase price. The collateral for all repurchase agreements is held in safekeeping in the customer-only account of the Fund's custodian or a subcustodian of the Fund. PIM is responsible for determining that the value of the collateral remains at least equal to the repurchase price. I. Purchased Options The Fund may purchase call and put options in order to seek to increase total return. Purchased call and put options entitle the Fund to buy and sell a specified number of shares or units of a particular security, currency or index at a specified price at a specific date or within a specific period of time. Pioneer Global High Yield Fund | Semiannual Report | 4/30/14 67 Upon the purchase of a call or put option, the premium paid by the Fund is included in the Statement of Assets and Liabilities as an investment. All premiums are marked-to-market daily, and any unrealized appreciation or depreciation are recorded in the Fund's financial statements. As the purchaser of an index option, the Fund has the right to receive a cash payment equal to any depreciation in the value of the index below the strike price of the option (in the case of a put) or equal to any appreciation in the value of the index over the strike price of the option (in the case of a call) as of the valuation date of the option. Premiums paid for purchased calls and put options which have expired are treated as realized losses on investments in the Statement of Operations. Upon the exercise or closing of a purchased put option, the premium is offset against the proceeds on the sale of the underlying security or financial instrument in order to determine the realized gain or loss on investments. Upon the exercise or closing of a purchased call option, the premium is added to the cost of the security or financial instrument. The risk associated with purchasing options is limited to the premium originally paid. The average value of contracts open during the six months ended April 30, 2014 was $33,289. Purchased put option contracts outstanding at period end are listed at the Fund's Schedule of Investments. 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 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. 68 Pioneer Global High Yield Fund | Semiannual Report | 4/30/14 The average value of contracts open during the six months ended April 30, 2014 was $45,575. Written call option contracts outstanding at period end are listed at the end of the Fund's schedule of investments. The Fund held one written call option contract that was open at April 30, 2014. If the put options were exercised at April 30, 2014, the maximum amount the Fund would have been required to pay was $81,114. Transactions in written call options for the six months ended April 30, 2014 are summarized as follows: ---------------------------------------------------------------------------- Number of Contracts Premium Received ---------------------------------------------------------------------------- Options open at beginning of period -- $ -- Options opened (4,923,449) (81,114) Options exercised -- -- Options closed -- -- Options expired -- -- ---------------------------------------------------------------------------- Options open at end of period (4,923,449) $ (81,114) ============================================================================ 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 six months ended April 30, 2014, the effective management fee (excluding waivers and/or assumption of expenses) was equivalent to 0.64% of the Fund's average daily net assets. PIM contractually agreed to limit ordinary operating expenses to the extent required to reduce Fund expenses to 1.10%, 2.00%, 2.00% and 0.90% of the average daily net assets attributable to Class A, Class B, Class C and Class Z shares, respectively. Class Y shares do not have an expense limitation. These expense limitations were in effect through March 1, 2013. 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. Pioneer Global High Yield Fund | Semiannual Report | 4/30/14 69 Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $75,100 in management fees, administrative costs and certain other reimbursements payable to PIM at April 30, 2014. 3. Transfer Agent PIMSS, a wholly owned indirect subsidiary of UniCredit, provides substantially all transfer agent and shareowner services to the Fund at negotiated rates. In addition, the Fund reimburses PIMSS for out-of-pocket expenses incurred by PIMSS related to shareholder communications activities such as proxy and statement mailings, outgoing phone calls and omnibus relationship contracts. For the six months ended April 30, 2014, such out-of-pocket expenses by class of shares were as follows: -------------------------------------------------------------------------------- Shareholder Communications: -------------------------------------------------------------------------------- Class A $283,551 Class B 17,446 Class C 195,541 Class Y 491,700 Class Z 5,635 -------------------------------------------------------------------------------- Total $996,873 ================================================================================ Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $401,299 in transfer agent fees and out-of-pocket reimbursements payable to PIMSS at April 30, 2014. 4. Basis for Consolidation of the Financial Statements The consolidated financial statements of the Fund include the accounts of Blaze Holding GHYDF, Inc. (the "Subsidiary"). All intercompany accounts and transactions have been eliminated in consolidation. The Subsidiary, a Delaware corporation, was incorporated on February 10, 2011 and is wholly-owned and controlled by the Fund. It is intended that the Fund will remain the sole shareholder of, and will continue to control, the Subsidiary. The Subsidiary acts as an investment vehicle for the Fund's interest in Blaze Recycling and Metals LLC, Class A Units. As of April 30, 2014, the Subsidiary represented approximately $396,958 or approximately 0.02% of the net assets of the Fund. 5. Distribution Plan The Fund has adopted a Distribution Plan pursuant to Rule 12b-1 of the Investment Company Act of 1940 with respect to its Class A, Class B and Class C shares. Pursuant to the Plan, the Fund pays PFD 0.25% of the average daily net assets attributable to Class A shares as compensation for personal services and/or account maintenance services or distribution 70 Pioneer Global High Yield Fund | Semiannual Report | 4/30/14 services with regard to Class A shares. Pursuant to the Plan, the Fund also pays PFD 1.00% of the average daily net assets attributable to Class B and Class C shares. The fee for Class B and Class C shares consists of a 0.25% service fee and a 0.75% distribution fee paid as compensation for personal services and/or account maintenance services or distribution services with regard to Class B and Class C shares. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $28,948 in distribution fees payable to PFD at April 30, 2014. In addition, redemptions of each class of shares (except Class Y and Class Z shares) may be subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may be imposed on redemptions of certain net asset value purchases of Class A shares within 12 months of purchase. Class B shares that are redeemed within five years of purchase are subject to a CDSC at declining rates beginning at 4.00%, based on the lower of cost or market value of shares being redeemed. Redemptions of Class C shares within 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 or Class Z shares. Proceeds from the CDSCs are paid to PFD. For the six month ended April 30, 2014, CDSCs in the amount of $17,192 were paid to PFD. 6. 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 February 12, 2014 was in the amount of $215 million. As of February 12, 2014, 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 0.90% (0.85% as of February 12, 2014) 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 Euro dollar 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 six month ended April 30, 2014, the Fund had no borrowings under the credit facility. Pioneer Global High Yield Fund | Semiannual Report | 4/30/14 71 7.

Expense Offset Arrangements The Fund has 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 six months ended April 30, 2014, the Fund's expenses were not reduced under such arrangements. 9. Forward Foreign Currency Contracts At April 30, 2014, 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 contracts open during the six months ended April 30, 2014 was $24,964,074. Open forward foreign currency contracts at April 30, 2014 were as follows: ------------------------------------------------------------------------------------------ Net Net In Unrealized Contracts Exchange Settlement Appreciation Currency to Deliver For Date Value (Depreciation) ------------------------------------------------------------------------------------------ EURO (European Euro) 440,000 $ 610,368 5/2/14 $ 610,226 $ (142) PHP (Philippine Peso) 307,400,000 6,863,139 5/13/14 6,895,166 32,027 RUB (Russian Ruble) 78,000,000 2,207,255 5/13/14 2,183,260 (23,995) EURO (European Euro) (5,000,000) 5,000,000 5/19/14 5,035,608 35,608 GBP (British Pound Sterling) (11,368,000) 19,194,564 5/19/14 18,897,685 (296,879) JPY (Japanese Yen) (1,191,551,081) 11,668,833 5/19/14 11,686,605 17,772 BRL (Brazilian Real) 4,000,000 1,664,655 6/6/14 1,772,906 108,251 NOK (Norwegian Krone) 100,000,000 16,698,749 6/6/14 16,805,400 106,651 EURO (European Euro) (2,725,000) 3,779,745 6/11/14 3,747,994 (31,751) EURO (European Euro) (7,000,000) 9,709,438 6/11/14 9,673,684 (35,754) EURO (European Euro) (1,831,569) 2,540,500 6/11/14 2,539,320 (1,180) EURO (European Euro) (17,000,000) 17,000,000 6/11/14 17,054,270 54,270 TRY (Turkish Lira) (5,802,689) 2,694,290 7/14/14 2,685,915 (8,375) ------------------------------------------------------------------------------------------ Total $ (43,497) ========================================================================================== 72 Pioneer Global High Yield Fund | Semiannual Report | 4/30/14 10.

Subsequent Events Change in Independent Registered Public Accounting Firm The Board of Trustees of the Fund, with the approval and recommendation of the Audit Committee, appointed Deloitte & Touche LLP to serve as the Fund's independent registered public accounting firm for the fiscal year ending October 31, 2014. Deloitte & Touche LLP replaces Ernst & Young LLP, which resigned as the Fund's independent registered public accounting firm, effective upon completion of the audit of the Fund's financial statements for the fiscal year ended October 31, 2013. During the periods that Ernst & Young LLP served as the Fund's independent registered public accounting firm, including the Fund's two most recent fiscal year, Ernst & Young LLP's reports on the financial statements of the Fund have not contained an adverse opinion or disclaimer of opinion and have not been qualified or modified as to uncertainty, audit scope or accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which, if not resolved to the satisfaction of Ernst & Young LLP would have caused Ernst & Young LLP to make reference to the subject matter of the disagreement in connection with its report on the financial statements. In addition, there have been no reportable events to the kind described in Item 304(a)(i)(v) of Regulation S-K under the Securities and Exchange Act of 1934. Pioneer Global High Yield Fund | Semiannual Report | 4/30/14 75 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 March 2013 as the Trustees of the Fund agreed on, among other things, an overall approach and timeline for the process. In July 2013, the Trustees approved the format of the contract review materials and submitted their formal request to PIM to furnish information necessary to evaluate the terms of the investment advisory agreement. The contract review materials were provided to the Trustees in July 2013 and September 2013. After reviewing and discussing the materials, the Trustees submitted a request for additional information to PIM, and materials were provided in response to this request. Meetings of the Independent Trustees of the Fund were held in July, September, and November, 2013 to review and discuss the contract review materials. In addition, the Trustees took into account the information related to the Fund provided to the Trustees at regularly scheduled meetings. At a meeting held on November 12, 2013, 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 considering the renewal of the investment advisory agreement, the Trustees considered various factors that they determined were relevant, including the factors described below. In all quintile rankings referred to throughout this disclosure, first quintile is most favorable to the Fund's shareowners. Thus, highest relative performance would be first quintile and lowest relative expenses would also be first quintile. The Trustees 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 reviewed the terms of the investment advisory agreement. The Trustees also reviewed PIM's investment approach for the Fund and its research process. The Trustees considered the resources of PIM and the personnel of PIM who provide investment management services to the Fund. They also 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 76 Pioneer Global High Yield Fund | Semiannual Report | 4/30/14 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 The Trustees review the Fund's performance on a regular basis, based on analysis and data prepared by PIM for this purpose and discuss performance issues with PIM on an ongoing basis. For purposes of their contract renewal deliberations, the Trustees considered the performance results of the Fund over various time periods. They reviewed information comparing the Fund's performance with the performance of its peer group of funds as classified by Morningstar, Inc. (Morningstar), an independent provider of investment company data, and with the performance of the Fund's benchmark index. The Trustees considered that the Fund's annualized total return was in the first quintile of its Morningstar category for the ten year period ended June 30, 2013, in the second quintile of its Morningstar category for the one year period ended June 30, 2013, in the fourth quintile of its Morningstar category for the three year period ended June 30, 2013, and in the fifth quintile of its Morningstar category for the five year period ended June 30, 2013. The Trustees also considered that the Fund's yield (for the twelve months ended June 30, 2013) exceeded the yield of the Fund's benchmark index for the same period. The Trustees noted the discussions held throughout the year regarding the Fund's performance and confirmed that those discussions were factored into the Trustees' deliberations concerning the renewal of the advisory agreement. The Trustees indicated that they were satisfied with the discussions with PIM with respect to the Fund's performance. 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 Pioneer Global High Yield Fund | Semiannual Report | 4/30/14 77 Independent Trustees for this purpose using data provided by Strategic Insight Mutual Fund Research and Consulting, LLC (Strategic Insight), an independent third party. The Trustees considered that the Fund's management fee for the twelve months ended June 30, 2013 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 twelve months ended June 30, 2013 was in the fifth quintile relative to its Strategic Insight peer group and in the fourth quintile relative to its Morningstar peer group, in each case for the comparable period, and that the expense ratio of the Fund's Class Y shares for the twelve months ended June 30, 2013 was in the fifth quintile relative to its Strategic Insight peer group and in the third quintile relative to its Morningstar peer group, in each case for the comparable period. The Trustees noted that the expense ratio of the Fund's Class A shares was approximately eleven basis points higher than the median expense ratio of its Strategic Insight peer group and approximately six basis points higher than the median expense ratio of its Morningstar peer group, and that the expense ratio of the Fund's Class Y shares was approximately ten basis points higher than the median expense ratio of its Strategic Insight peer group and approximately three basis points higher than the median expense ratio of its Morningstar peer group. 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 PIM and PIM's affiliate, Pioneer Institutional Asset Management, Inc. (together with PIM, "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 78 Pioneer Global High Yield Fund | Semiannual Report | 4/30/14 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. 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. 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, rarely identifiable on a fund-by-fund basis, 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 particularly, for example during the recent difficult periods for financial markets, as the level of services was maintained notwithstanding a significant decline in PIM's fee revenues from the Fund. Accordingly, the Trustees concluded that economies of scale, if any, were being appropriately shared with the Fund. Pioneer Global High Yield Fund | Semiannual Report | 4/30/14 79 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. The Trustees considered the intangible benefits to PIM by virtue of its relationship with the Fund and the other Pioneer funds. The Trustees concluded that the receipt of these benefits was reasonable in the context of the overall relationship between PIM and the Fund. Conclusion After consideration of the factors described above as well as other factors, the Trustees, including all of the Independent Trustees, concluded that the 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. 80 Pioneer Global High Yield Fund | Semiannual Report | 4/30/14 Trustees, Officers and Service Providers Trustees Officers Thomas J.

Consumer incomes, savings, wealth, and debt-servicing capacity have been solid buttresses for the recovering housing and auto industries. Industrial activity is growing only moderately, but current corporate profits are generally solid and balance sheets appear able to support needed capital spending and dividend* payouts. A modestly improving European economy and continuing economic improvement in Japan appear likely to result in improving global growth in 2014, further supporting the U.S. economy. In addition, we feel that continuing slack in labor markets and capacity utilization offer the potential for continuing growth without bottlenecks and rising inflation. After observing the strengthening economic trends, the Federal Reserve System (the Fed) has begun scaling back its QE (quantitative easing) program, but short-term interest rates remain near zero, and while Fed Chair Janet Yellen has suggested that rates may be raised roughly six months after the QE program is fully tapered, that would still place the potential rate hike sometime in 2015. There are certainly risks and uncertainties still facing the global economy as 2014 moves along. The European economy, while improving, remains weak, the Japanese economy faced a tax hike this spring, and a number of emerging market countries are experiencing difficulties. There are also geopolitical worries abroad, such as Russia's aggressive move against the Ukraine, and more potential political fights at home, especially during a mid-term election year. While most of the widely recognized risks we have outlined may already be "priced into" the market, we believe investors should continue to expect market volatility. At Pioneer, we have long advocated the benefits of staying diversified and investing for the long term. And while diversification does not assure a profit or protect against loss in a declining market, we believe there are still opportunities for prudent investors to earn attractive returns. Our advice, as always, is to work closely with a trusted financial advisor to discuss your goals and work together to develop an investment strategy that meets your individual needs, keeping in mind that there is no single best strategy that works for every investor. * Dividends are not guaranteed. 2 Pioneer Global Multisector Income Fund | Semiannual Report | 4/30/14 Pioneer's investment teams have, since 1928, sought out attractive opportunities in equity and bond markets, using in-depth research to identify undervalued individual securities, and using thoughtful risk management to construct portfolios which seek to balance potential risks and rewards in an ever-changing world. We encourage you to learn more about Pioneer and our time-tested approach to investing by consulting with your financial advisor or visiting us online at us.pioneerinvestments.com. We greatly appreciate your trust in us, and we thank you for investing with Pioneer. Sincerely, /s/ Daniel K. Kingsbury Daniel K. Kingsbury President and CEO Pioneer Investment Management USA, Inc.

Pioneer Global Multisector Income Fund | Semiannual Report | 4/30/14 3 Portfolio Management Discussion | 4/30/14 The U.S. economy continued to grow at a moderate pace over the six-month period ended April 30, 2014, while the European economy emerged from recession and many emerging markets rallied after being hit hard by earlier worries about rising interest rates and a shortage of capital. Some emerging markets, however, remained vulnerable to slowing growth trends in China. In the following interview, Charles Melchreit and Paresh Upadhyaya discuss the factors that affected the performance of Pioneer Global Multisector Income Fund during the six-month period. Mr. Melchreit, a senior vice president and 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, a senior vice president and portfolio manager at Pioneer+. Q How did the Fund perform during the six-month period ended April 30, 2014? A The Fund's Class A shares returned 1.89% at net asset value during the six-month period ended April 30, 2014, while the Fund's benchmark, the Barclays Global Aggregate Bond Index (the Barclays Index), returned 2.10%. During the same period, the average return of the 227 mutual funds in Lipper's Global Income Funds category was 2.57%, and the average return of the 398 mutual funds in Morningstar's World Bond Funds category was 2.53%. Q How would you describe the investment environment for global bonds during the six-month period ended April 30, 2014? A The six-month period produced positive performance by many fixed-income markets, highlighted by stabilization of markets in the U.S., a bounce-back in performance from emerging markets securities, and surprising strength in Europe. Rising geopolitical tensions also affected the markets, with worries about Syria dominating concerns early in the period, and political and military tensions between the Ukraine and Russia capturing headlines towards the end of the six months. + Effective August 1, 2013, Pioneer Global Aggregate Bond Fund was renamed Pioneer Global Multi-sector Income Fund. In addition, effective August 1, 2013, the Fund changed its investment objective and certain investment policies and strategies, and Kenneth Taubes, Andrew Feltus, and Paresh Upadhyaya joined Charles Melchreit as portfolio managers of the Fund. Please see the prospectus for more information. 4 Pioneer Global Multisector Income Fund | Semiannual Report | 4/30/14 In the United States, the economy continued to grow at modest rates, supporting the performance of credit-linked debt in particular, including high-yield and investment-grade corporate bonds. U.S. Treasury interest rates stabilized over the six months following a period of high volatility during which market rates fluctuated sharply in reaction to the expectation that the Federal Reserve ("Fed") would start withdrawing some of its monetary stimulus from the economy by beginning to taper its quantitative easing (QE) bond-buying program. Emerging markets in general performed well during the six-month period after being hit hard in the spring and early summer of 2013, when investors withdrew money because of worries that higher interest rates in the United States would lead to reductions in the flow of capital to developing nations. That development had led to sharp declines in asset prices and currency values, especially in those economies with the largest current account deficits, such as Turkey, South Africa, Brazil, India and Indonesia. In the aftermath, even as Treasury rates in the United States stabilized, many major emerging nations, including Indonesia, India and Brazil, adjusted their fiscal and monetary policies, resulting in impressive recoveries in their markets. Investors grew more confident that economic fundamentals in the emerging markets had improved and that current account deficits could be financed. Meanwhile, new geopolitical tensions arose, highlighted by the emergence of nationalist, anti-Russian protests in the Ukraine that led the country's pro-Russian President to flee the country. In response, Russia took control of the strategically important Crimean region, which was part of the Ukraine. Elsewhere, economic growth in China continued to slow as the country's leadership tightened monetary policy and began the process of moving the nation to a more consumer-oriented economy. The move resulted in sharp reductions in credit growth, which in turn reduced demand for materials such as copper, iron and coal. The European economy emerged from recession during the six-month period. The peripheral southern European nations performed particularly well as the euro currency gained in relative value amid renewed investor buying of peripheral market bonds. Pioneer Global Multisector Income Fund | Semiannual Report | 4/30/14 5 Finally, progress in Japan slowed as investors awaited evidence that the Japanese government would follow through on expectations of major structural economic reforms. Q How did the Fund's positioning influence performance relative to the Barclays Index during the six-month period ended April 30, 2014? A The Fund slightly underperformed the Barclays Index during the period. The portfolio's overall currency positioning detracted from the Fund's relative performance, mainly due to underweighted exposures to the euro and the British pound, which rallied as the European economy emerged from recession, and to bonds issued by peripheral European nations such as Greece and Portugal, which attracted more demand during the period. The portfolio's overweighted position in the Russian ruble also held back the Fund's performance. The Fund's overall duration positioning held back benchmark-relative results during the period, primarily because of the portfolio's short- duration stance in Europe, where interest rates declined, and because of longer-duration positioning in Russia and the Philippines, where interest rates backed up. (Duration is intended to be a measure of a portfolio's price sensitivity to changes in interest rates.) On the positive side, the portfolio's shorter-duration position in the United States helped performance as interest rates rose, and longer-duration stances in both Mexico and Norway also helped performance as interest rates in both countries declined. Good sector allocation and security selection decisions aided the Fund's performance during the period. Sector allocations were particularly beneficial for relative performance, especially the portfolio's emphasis on the credit sectors, where the Fund experienced solid performance from investments in corporate bonds, with issues in the financials and industrials sectors outperforming. Good security selection within the Fund's corporate bond allocation also added to performance. In addition, overweights to commercial mortgages and asset-backed securities and a de-emphasizing of government agency debt boosted the Fund's results, as did modest portfolio exposure to municipal bonds. Further supporting the Fund's performance during the period were the portfolio's underweighted positions in the currencies of Canada, the Czech Republic and Chile, and overweighted positions in the currencies of Poland 6 Pioneer Global Multisector Income Fund | Semiannual Report | 4/30/14 and Romania. The Fund's overall currency positioning during the period was based on our confidence in the U.S. dollar, which we thought would strengthen because of our more positive growth outlook for the U.S. economy (a strengthening economy would likely drive interest rates higher)--especially compared with the outlooks (both for growth and interest rates) for other major economies. At the end of the period, we remained bullish about the prospects for the U.S. dollar. At the end of the period, on April 30, 2014, U.S. corporate debt, both investment-grade (18% of net assets) and high-yield (7% of net assets), represented the Fund's largest sector allocation, followed by emerging markets bonds, which accounted for nearly 20% of net assets. International investment-grade bonds were another large allocation as of period end, representing nearly 18% of the Fund's net assets. Q Did you use any derivative investments when managing the Fund during the six-month period ended April 30, 2014? A Yes, the Fund used some currency forward contracts to hedge the risks in the portfolio arising from volatility in the relative values of different currencies. The use of these contracts had a modestly positive influence on the Fund's results during the six-month period. Q What is your investment outlook? A We retain a positive view on the economic growth outlook in general and especially for the United States, where we think the economy should continue to expand at a moderate pace and inflationary pressures should remain somewhat muted. The Fed is likely to wind down its QE program by the end of this calendar year; however, the European Central Bank and the Bank of Japan seem more likely to move to ease their region's monetary policies further and to push interest rates lower. Going forward, we believe the U.S. economy is likely to generate a growth rate that is above long-term averages, and that other developed markets also should see their economies strengthen. Economies in the emerging markets also should improve, but growth rates are more likely to be lower than potential gross domestic product. China's economy, in particular, may continue to slow, which will have effects on some other emerging markets that are dependent on exports of materials to China. In addition, geopolitical risks remain, and it always is possible that new or heightened tensions could arise in areas that had been considered quiet. Pioneer Global Multisector Income Fund | Semiannual Report | 4/30/14 7 The overall positive outlook for global economic growth should continue to support healthy corporate earnings, and we remain positive about the prospects for the performance of credit-sensitive securities, especially corporate bonds. In addition, we think the U.S. dollar is likely to be supported by relatively stronger macroeconomic fundamentals and the Fed's reduced monetary accommodation. Please refer to the Schedule of Investments on pages 17-39 for a full listing of Fund securities. Investing in foreign and/or emerging markets securities involves risks relating to interest rates, currency exchange rates, economic, and political conditions. 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 portfolio may invest in mortgage-backed securities, which during times of fluctuating interest rates may increase or decrease more than other fixed-income securities. Mortgage-backed securities are also subject to pre-payments. The 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. 8 Pioneer Global Multisector Income Fund | Semiannual Report | 4/30/14 These risks may increase share price volatility.

This example is intended to help you understand your ongoing expenses (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 at the beginning of the Fund's latest six-month period and held throughout the six months. Using the Tables -------------------------------------------------------------------------------- Actual Expenses The first table below provides information about actual account values and actual expenses. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period as follows: (1) Divide your account value by $1,000 Example: an $8,600 account value (divided by) $1,000 = 8.6 (2) Multiply the result in (1) above by the corresponding share class's number in the third row under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Expenses Paid on a $1,000 Investment in Pioneer Global Multisector Income Fund Based on actual returns from November 1, 2013 through April 30, 2014. -------------------------------------------------------------------------------- Share Class A C Y -------------------------------------------------------------------------------- Beginning Account Value on 11/1/13 $1,000.00 $1,000.00 $1,000.00 -------------------------------------------------------------------------------- Ending Account Value (after expenses) on 4/30/14 $1,018.90 $1,015.30 $1,021.10 -------------------------------------------------------------------------------- Expenses Paid During Period* $ 5.01 $ 9.49 $ 3.76 -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized net expense ratio of 1.00%, 1.90%, and 0.75% for Class A, Class C, and Class Y respectively, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the partial year period). Pioneer Global Multisector Income Fund | Semiannual Report | 4/30/14 15 Hypothetical Example for Comparison Purposes The table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads) that are charged at the time of the transaction. Therefore, the table below is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher.

Organization and Significant Accounting Policies Pioneer Global Multisector Income Fund (formerly known as Pioneer Global Aggregate Bond Fund) (the Fund) is a series of Pioneer Series Trust VII, a Delaware statutory trust. The Fund is registered under the Investment Company Act of 1940 as a diversified, open-end management investment company. The investment objective of the Fund is to provide a high level of current income. The Fund offers three classes of shares designated as Class A, Class C, and Class Y shares. Class A, Class C, and Class Y shares were first publicly offered on December 28, 2007. Each class of shares represents an interest in the same portfolio of investments of the Fund and has identical rights (based on relative net asset values) to assets and liquidation proceeds. Share classes can bear different rates of class-specific fees and expenses such as transfer agent and distribution fees. Differences in class-specific fees and expenses will result in differences in net investment income and, therefore, the payment of different dividends from net investment income earned by each class. The Amended and Restated Declaration of Trust of the Fund gives the Board the flexibility to specify either per-share voting or dollar-weighted voting when submitting matters for shareholder approval. Under per-share voting, each share of a class of the Fund is entitled to one vote. Under dollar-weighted voting, a shareholder's voting power is determined not by the number of shares owned, but by the dollar value of the shares on the record date. Each share class has exclusive voting rights with respect to matters affecting only that class, including with respect to the distribution plan for that class. There is no distribution plan for Class Y shares. The Fund's financial statements have been prepared in conformity with U.S. generally accepted accounting principles that require the management of the Fund to, among other things, make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income, expenses and gain or loss on investments during the reporting period. Actual results could differ from those estimates. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements, which are consistent with those policies generally accepted in the investment company industry: Pioneer Global Multisector Income Fund | Semiannual Report | 4/30/14 47 A. Security Valuation Security transactions are recorded as of trade date. The net asset value of the Fund is computed once daily, on each day the New York Stock Exchange (NYSE) is open, as of the close of regular trading on the NYSE. Senior floating rate loan interests (senior loans) are valued in accordance with guidelines established by the Board of Trustees at the mean between the last available bid and asked prices from one or more brokers or dealers as obtained from Loan Pricing Corporation, an independent pricing service. 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. Fixed income securities with remaining maturity of more than sixty days are valued at prices supplied by independent pricing services, which consider such factors as market prices, market events, quotations from one or more brokers, Treasury spreads, yields, maturities and ratings. Valuations may be supplemented by dealers and other sources, as required. Equity securities that have traded on an exchange are valued at the last sale price on the principal exchange where they are traded. Equity securities that have not traded on the date of valuation, or securities for which sale prices are not available, generally are valued using the mean between the last bid and asked prices. Short-term fixed income securities with remaining maturities of sixty days or less generally are valued at amortized cost. 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 loan interests 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. 48 Pioneer Global Multisector Income Fund | Semiannual Report | 4/30/14 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 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 April 30, 2014, 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). Principal amounts of mortgage-backed securities are adjusted for monthly paydowns. Premiums and discounts related to certain mortgage-backed securities are amortized or accreted in proportion to the monthly paydowns. All discounts/premiums on debt securities are accreted/amortized for financial reporting purposes over the life of the respective securities, and such accretion/amortization is included in interest income. Dividend income is recorded on the ex-dividend date, except that certain dividends from foreign securities where the ex-dividend date may have passed are recorded as soon as the Fund becomes aware of the ex-dividend data in the exercise of reasonable diligence. Interest income, including interest on income bearing cash accounts, is recorded on the accrual basis. Dividend and interest income are reported net of unrecoverable foreign taxes withheld at the applicable country rates. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. B. Foreign Currency Translation The books and records of the Fund are maintained in U.S. dollars. Amounts denominated in foreign currencies are translated into U.S. dollars using current exchange rates. Net realized gains and losses on foreign currency transactions, if any, represent, among other things, the net realized gains and losses on foreign currency contracts, disposition of foreign currencies and the difference between the amount of income accrued and the U.S. dollars actually received. Further, the effects of changes in foreign currency exchange rates on investments are not segregated in the statement of operations from the effects of changes in the market prices of those securities but are included with the net realized and unrealized gain or loss on investments. Pioneer Global Multisector Income Fund | Semiannual Report | 4/30/14 49 C. Forward Foreign Currency Contracts The Fund may enter into forward foreign currency contracts (contracts) for the purchase or sale of a specific foreign currency at a fixed price on a future date. All contracts are marked to market daily at the applicable exchange rates, and any resulting unrealized 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). D. Federal Income Taxes It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income and net realized capital gains, if any, to its shareowners. Therefore, no provision for federal income taxes is required. As of April 30, 2014, 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. The tax character of current year distributions payable will be determined at the end of the current table year. The tax character of distributions paid during the year ended October 31, 2013 was as follows: --------------------------------------------------------------------------- 2013 --------------------------------------------------------------------------- Distributions paid from: Ordinary income $ 875,669 Long-term capital gain 276,652 --------------------------------------------------------------------------- Total $1,152,321 =========================================================================== Pioneer Global Multisector Income Fund | Semiannual Report | 4/30/14 50 The following shows the components of distributable earnings on a federal income tax basis at October 31, 2013: --------------------------------------------------------------------------- 2013 --------------------------------------------------------------------------- Distributable earnings: Undistributed long-term gain $ 162,320 Current year dividend payable (59,773) Unrealized appreciation 428,940 --------------------------------------------------------------------------- Total $ 531,487 =========================================================================== The difference between book-basis and tax-basis net unrealized appreciation 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. E. Fund Shares The Fund records sales and repurchases of its shares as of trade date. Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the Fund and a wholly-owned indirect subsidiary of UniCredit S.p.A. (UniCredit), earned $297 in underwriting commissions on the sale of Class A shares during the six months ended April 30, 2014. F. Class Allocations Income, common expenses and realized and unrealized gains and losses are calculated at the Fund level and allocated daily to each class of shares based on its respective percentage of adjusted net assets at the beginning of the day. Distribution fees are calculated based on the average daily net asset value attributable to Class A and Class C shares of the Fund, respectively (see Note 4). Class Y shares do not pay distribution fees. All expenses and fees paid to the transfer agent, Pioneer Investment Management Shareholder Services, Inc. (PIMSS), for its services are allocated among the classes of shares based on the number of accounts in each class and the ratable allocation of related out-of-pocket expenses (see Note 3). The Fund declares as daily dividends substantially all of its net investment income. All dividends are paid on a monthly basis. Short-term capital gain distributions, if any, may be declared with the daily dividends. Distributions to shareowners are recorded as of the ex-dividend date. Distributions paid by the Fund with respect to each class of shares are calculated in the same manner and at the same time, except that net investment income dividends to Class A, Class C and Class Y shares can reflect different transfer agent and distribution expense rates.

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. H. 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 April 30, 2014 was $22,500. 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 the exchange's clearinghouse, as counterparty to all exchange-traded futures, guarantees the futures against default. The average value of contracts open during the six months ended April 30, 2014 was $1,361,042. 52 Pioneer Global Multisector Income Fund | Semiannual Report | 4/30/14 At April 30, 2014, open futures contracts were as follows: ------------------------------------------------------------------------------------ Number of Net Contracts Settlement Unrealized Type Long/(Short) Month Value Depreciation ------------------------------------------------------------------------------------ FC US 5 Yr Note (CBT) (5) 6/14 $ (594,765) $ (2,500) US Long Bond (CBT) (4) 6/14 $ (527,875) $(11,875) US 10 Yr Note (CBT) (6) 6/14 $ (740,813) $ (5,719) ------------------------------------------------------------------------------------ Total (15) $(1,863,453) $(20,094) ------------------------------------------------------------------------------------ I. Repurchase Agreements With respect to repurchase agreements entered into by the Fund, the value of the underlying securities (collateral), including accrued interest, is required to be equal to or in excess of the repurchase price. The collateral for all repurchase agreements is held in safekeeping in the customer-only account of the Fund's custodian or a subcustodian of the Fund. PIM is responsible for determining that the value of the collateral remains at least equal to the repurchase price. 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 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 six months ended April 30, 2014 was $779. Written call option contracts outstanding at period end are listed at the end of the Fund's schedule of investments. The Fund held one written put option contract that were open at April 30, 2014. If the put option was exercised at April 30, 2014, the maximum amount the Fund would have been required to pay was $508. Pioneer Global Multisector Income Fund | Semiannual Report | 4/30/14 53 Transactions in written options for the six months ended April 30, 2014 are summarized as follows: --------------------------------------------------------------------------------- Number of Contracts Premium Paid --------------------------------------------------------------------------------- Options open at beginning of period -- $ -- Options opened 84,202 (1,388) Options exercised -- -- Options closed -- -- Options expired -- -- --------------------------------------------------------------------------------- Options open at end of period 84,202 $(1,388) ================================================================================= K. Purchased Options The Fund may purchase call and put option in order to seek to increase total return. Purchased call and put options entitle the Fund to buy and sell a specified number of shares or units of a particular security, currency or index at a specified price at a specific date or within a specific period of time. Upon the purchase of a call or put option, the premium paid by the Fund is included in the Statement of Assets and Liabilities as an investment. All premiums are marked-to-market daily, and any unrealized appreciation or depreciation are recorded in the Fund's financial statements. As the purchaser of an index option, the Fund has the right to receive a cash payment equal to any depreciation in the value of the index below the strike price of the option (in the case of a put) or equal to any appreciation in the value of the index over the strike price of the option (in the case of a call) as of the valuation date of the option. Premiums paid for purchased calls and put options which have expired are treated as realized losses on investments in the Statement of Operations. Upon the exercise or closing of a purchased put option, the premium is offset against the proceeds on the sale of the underlying security or financial instrument in order to determine the realized gain or loss on investments. Upon the exercise or closing of a purchased call option, the premium is added to the cost of the security or financial instrument. The risk associated with purchasing options is limited to the premium originally paid. The average value of purchased options open during the six months ended April 30, 2014 was $569. Purchased option contracts outstanding at period end are listed at the end of the Fund's schedule of investments. 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. 54 Pioneer Global Multisector Income Fund | Semiannual Report | 4/30/14 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 six months ended April 30, 2014 are reflected on the Statement of Operations. These expense limitations are in effect through March 1, 2015. 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 $2,673 in management fees, administrative costs and certain other reimbursements due to PIM at April 30, 2014. 3. Transfer Agent PIMSS, a wholly owned indirect subsidiary of UniCredit, provides substantially all transfer agent and shareowner services to the Fund at negotiated rates. In addition, the Fund reimburses PIMSS for out-of-pocket expenses incurred by PIMSS related to shareholder communications activities such as proxy and statement mailings, outgoing phone calls and omnibus relationship contracts. For the six months ended April 30, 2014, such out-of-pocket expenses by class of shares were as follows: -------------------------------------------------------------------------------- Shareholder Communications: -------------------------------------------------------------------------------- Class A $2,275 Class C 901 Class Y 224 -------------------------------------------------------------------------------- Total: $3,400 ================================================================================ Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $1,965 in transfer agent fees and out-of-pocket reimbursements payable to PIMSS at April 30, 2014. 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 Pioneer Global Multisector Income Fund | Semiannual Report | 4/30/14 55 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 distribution services with regard to Class C shares. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $309 in distribution fees payable to PFD at April 30, 2014. 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 purchases 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 six months ended April 30, 2014, CDSCs in the amount of $13 were paid to PFD. 5. Expense Offset Arrangements The Fund has 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 six months ended April 30, 2014, the Fund's expenses were not reduced under such arrangements. 6. Forward Foreign Currency Contracts At April 30, 2014, 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 six months ended April 30, 2014 was $5,632,734. 56 Pioneer Global Multisector Income Fund | Semiannual Report | 4/30/14 -------------------------------------------------------------------------------------------------------- Net Net In Unrealized Contracts Exchange Settlement Appreciation Currency to Deliver For Date Value (Depreciation) -------------------------------------------------------------------------------------------------------- AUD (Australian Dollar) $ (372,214) $ (336,449) 6/6/14 $ (345,087) $ (8,638) AUD (Australian Dollar) (120,554) (111,784) 5/1/14 (112,043) (259) BRL (Brazilian Real) 350,000 145,657 6/6/14 155,129 9,472 CLP (Chilean Peso) (150,000,000) (259,502) 6/18/14 (264,355) (4,853) CZK (Czech Koruna) (13,500,000) (688,440) 6/20/14 (682,056) 6,384 EURO (European Euro) (215,075) (297,358) 7/16/14 (298,302) (944) EURO (European Euro) (1,366,271) (1,894,223) 6/11/14 (1,895,104) (881) EURO (European Euro) (107,614) (148,574) 6/11/14 (149,267) (693) EURO (European Euro) (93,140) (128,708) 7/16/14 (129,182) (474) EURO (European Euro) 216,189 298,524 5/2/14 299,897 1,373 GBP (British Pound Sterling) (110,000) (182,859) 5/19/14 (185,732) (2,873) HUF (Hungarian Forint) (66,994,656) (297,602) 6/6/14 (302,193) (4,591) JPY (Japanese Yen) (38,079,469) (373,479) 5/19/14 (372,911) 568 MXN (Mexican Peso) 3,813,010 289,380 6/11/14 290,685 1,305 NOK (Norwegian Krone) (1,794,563) (298,524) 5/2/14 (302,018) (3,494) NZD (New Zealand Dollar) (85,041) (69,409) 5/7/14 (73,309) (3,900) PHP (Philippine Peso) 13,300,000 296,941 5/13/14 298,327 1,386 PLN (Polish Zloty) 2,083,941 688,440 6/20/14 686,407 (2,033) RON (Romanian New Leu) 965,480 297,602 6/6/14 300,973 3,371 RUB(Russian Ruble) 4,400,000 124,512 5/13/14 123,158 (1,354) RUB(Russian Ruble) (4,399,799) (123,037) 5/13/14 (123,153) (116) TRY (Turkish Lira) (234,338) (108,469) 7/14/14 (108,807) (338) ZAR (South African Rand) (3,129,440) (289,380) 6/11/14 (295,902) (6,522) -------------------------------------------------------------------------------------------------------- Total $(18,104) ======================================================================================================== Pioneer Global Multisector Income Fund | Semiannual Report | 4/30/14 57 7.

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 February 12, 2014 was in the amount of $215 million. As of February 12, 2014, 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 0.90% (0.85% as of February 12, 2014) 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 six months ended April 30, 2014, the Fund had no borrowings under the credit facility. 10. Subsequent Event Change in Independent Registered Public Accounting Firm The Board of Trustees of the Fund, with the approval and recommendation of the Audit Committee, appointed Deloitte & Touche LLP to serve as the Fund's independent registered public accounting firm for the fiscal year ending October 31, 2014. Deloitte & Touche LLP replaces Ernst & Young LLP, which resigned as the Fund's independent registered public accounting firm, effective upon completion of the audit of the Fund's financial statements for the fiscal year ended October 31, 2013. During the periods that Ernst & Young LLP served as the Fund's independent registered public accounting firm, including the Fund's two most recent fiscal year, Ernst & Young LLP's reports on the financial statements of the Fund have not contained an adverse opinion or disclaimer of opinion and have not been qualified or modified as to uncertainty, audit scope or accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which, if not resolved to the satisfaction of Ernst & Young LLP would have caused Ernst & Young LLP to make reference to the subject matter of the disagreement in connection with its report on the financial statements. In addition, there have been no reportable events to the kind described in Item 304(a)(i)(v) of Regulation S-K under the Securities and Exchange Act of 1934. 60 Pioneer Global Multisector Income Fund | Semiannual Report | 4/30/14 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 March 2013 as the Trustees of the Fund agreed on, among other things, an overall approach and timeline for the process. In July 2013, the Trustees approved the format of the contract review materials and submitted their formal request to PIM to furnish information necessary to evaluate the terms of the investment advisory agreement. The contract review materials were provided to the Trustees in July 2013 and September 2013. After reviewing and discussing the materials, the Trustees submitted a request for additional information to PIM, and materials were provided in response to this request. Meetings of the Independent Trustees of the Fund were held in July, September, and November, 2013 to review and discuss the contract review materials. In addition, the Trustees took into account the information related to the Fund provided to the Trustees at regularly scheduled meetings. At a meeting held on November 12, 2013, 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 considering the renewal of the investment advisory agreement, the Trustees considered various factors that they determined were relevant, including the factors described below. In all quintile rankings referred to throughout this disclosure, first quintile is most favorable to the Fund's shareowners. Thus, highest relative performance would be first quintile and lowest relative expenses would also be first quintile. The Trustees 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 reviewed the terms of the investment advisory agreement. The Trustees also reviewed PIM's investment approach for the Fund and its research process. The Trustees considered the resources of PIM and the personnel of PIM who provide investment management services to the Fund. They also reviewed the amount of non-Fund assets managed by the portfolio managers of the Fund. The Trustees considered the Pioneer Global Multisector Income Fund | Semiannual Report | 4/30/14 61 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 administra- tor, 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 The Trustees review the Fund's performance on a regular basis, based on analysis and data prepared by PIM for this purpose and discuss performance issues with PIM on an ongoing basis. For purposes of their contract renewal deliberations, the Trustees considered the performance results of the Fund over various time periods. They reviewed information comparing the Fund's performance with the performance of its peer group of funds as classified by Morningstar, Inc. (Morningstar), an independent provider of investment company data, and with the performance of the Fund's benchmark index. The Trustees considered that the Fund's annualized total return was in the third quintile of its Morningstar category for the one year period ended June 30, 2013, and in the second quintile of its Morningstar category for the three and five year periods ended June 30, 2013. The Trustees also considered that the Fund's yield (for the twelve months ended June 30, 2013) exceeded the yield of the Fund's benchmark index for the same period. The Trustees noted the discussions held throughout the year regarding the Fund's performance and confirmed that those discussions were factored into the Trustees' deliberations concerning the renewal of the advisory agreement. The Trustees concluded that the investment performance of the Fund was satisfactory. 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. 62 Pioneer Global Multisector Income Fund | Semiannual Report | 4/30/14 The Trustees considered that the Fund's management fee for the twelve months ended June 30, 2013 was in the second 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 twelve months ended June 30, 2013 was in the second quintile relative to its Morningstar peer group and in the first quintile relative to its Strategic Insight peer group, in each case for the comparable period. The Trustees also considered that the expense ratio of the Fund's Class Y shares for the twelve months ended June 30, 2013 was in the fourth quintile relative to its Morningstar peer group and in the first quintile relative to 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 that, taking into account the contractual expense limitation agreed to by PIM with respect to Class Y shares of the Fund, the expense ratio of the Fund's Class Y shares for the twelve months ended June 30, 2013 would be in the third quintile relative to its Morningstar peer group. The Trustees reviewed management fees charged by PIM and PIM's affiliate, Pioneer Institutional Asset Management, Inc. (together with PIM, "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 serv- ices 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. 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. 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 Pioneer Global Multisector Income Fund | Semiannual Report | 4/30/14 63 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, rarely identifiable on a fund-by-fund basis, 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 particularly, for example during the recent difficult periods for financial markets, as the level of services was maintained notwithstanding a significant decline in PIM's fee revenues from the Fund. Accordingly, the Trustees concluded that economies of scale, if any, were being appropriately shared with the Fund. 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. The Trustees considered the intangible benefits to PIM by virtue of its relationship with the Fund and the other Pioneer funds. The Trustees concluded that the receipt of these benefits was reasonable in the context of the overall relationship between PIM and the Fund.

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.
