Yet, it is becoming increasingly clear that the investment landscape is undergoing significant change. For the past eight years, global central banks have been the dominant force in the markets by maintaining government bond yields at close to zero in an effort to stimulate economic growth. With little room to lower rates further, however, central banks may be losing their effectiveness. Many economies around the world are experiencing slow growth as they face a variety of challenges, including the shifting geopolitics driving "Brexit" - the United Kingdom's pending exit from the European Union - as well as related movements in Europe, limited productivity gains, aging populations, and transitioning economic models in China and other emerging markets. In the United States, gross domestic product (GDP) grew at a rate of approximately 1.2% in the first half of 2016, but GDP growth registered a strong uptick in the third quarter of the year, driven primarily by U.S. consumers. Investors currently face a difficult environment. Government bond yields, as noted earlier, had been near zero for most of the year and offered minimal opportunity to produce income. However, recent developments such as the Federal Reserve's decision to increase the Federal funds rate before the end of 2016 have driven yields slightly higher. The central bank-driven bull market in riskier assets has pushed up valuations towards historic highs in the equity and investment-grade and high-yield corporate bond markets. Central banks have pledged to move gradually to normalize interest-rate policies as the global economy recovers, but it may take many years for this historic credit cycle to unwind. Politics may also influence markets or investor sentiment given the current global political landscape. Donald Trump's victory in the November U.S. presidential election seems to have sparked a late-year market rally, given the pro-growth proposals he promoted on the campaign trail, but it is unclear just how many of his policy initiatives will be implemented. In addition, continued challenges with Brexit and other geopolitical issues have the potential to increase market volatility going forward. Against this backdrop, investors are likely to face ongoing challenges when it comes to finding opportunities for both income and capital appreciation, and while much has been made of passive investing, we believe all investment decisions are active choices. 2 Pioneer Emerging Markets Fund | Annual Report | 11/30/16 Throughout Pioneer's history, we have believed in the importance of active management. During challenging market conditions, we view the value of active management as even more compelling. Our experienced and tenured investment teams focus on identifying value across global markets using proprietary research, careful risk management, and a long-term perspective. We believe our shareowners can benefit from the experience and tenure of our investment teams as well as the insights generated from our extensive research process. As always, and particularly during times of market uncertainty, we encourage you to work with your financial advisor to develop an overall investment plan that addresses both your short- and long-term goals, and to implement such a plan in a disciplined manner. We greatly appreciate the trust you have placed in us and look forward to continuing to serve you in the future. Sincerely, /s/ Lisa M. Jones Lisa M.

Pioneer Emerging Markets Fund | Annual Report | 11/30/16 3 Portfolio Management Discussion | 11/30/16 In the following interview, Mauro Ratto, Marco Mencini, and Andrea Salvatori, portfolio managers of Pioneer Emerging Markets Fund, discuss the investment environment and the Fund's performance during the 12-month period ended November 30, 2016. Mr. Ratto, Head of Emerging Markets Investment Management at Pioneer, Mr. Mencini, Head of Equities, Emerging Markets, and a senior vice president at Pioneer, and Mr. Salvatori, Head of Global Emerging Markets & Latin American Equities, a senior vice president and a senior portfolio manager at Pioneer, are responsible for the day-to-day management of the Fund. Q How did the Fund perform during the 12-month period ended November 30, 2016? A Pioneer Emerging Markets Fund's Class A shares returned 6.13% at net asset value during the 12-month period ended November 30, 2016, while the Fund's benchmark, the Morgan Stanley Capital International (MSCI)Emerging Markets ND Index (the MSCI Index1), returned 8.47%. During the same period, the average return of the 840 mutual funds in Lipper's Emerging Markets Funds category was 5.56%, and the average return of the 810 mutual funds in Morningstar's Diversified Emerging Markets Funds category was 5.63%. Q Could you please review the performance of emerging markets stocks during the 12-month period ended November 30, 2016? A After experiencing weakness in the initial months of the reporting period, emerging markets stocks recovered nicely and finished the Fund's fiscal year with a healthy gain. The early downturn marked a continuation of the poor performance of emerging markets stocks that characterized the second half 1 The MSCI information may only be used for your internal use, may not be reproduced or re-disseminated in any form and may not be used as a basis for or a component of any financial instruments or products or indices.

The backdrop changed for the better in mid-February 2016, however, when the Bank of Japan and the European Central Bank both cut short-term interest rates to below zero. In addition, investors became encouraged that the U.S. Federal Reserve (the Fed) would maintain its low-rate policy for an extended period in the wake of its small interest-rate hike in December 2015, its first in several years. The actions taken by central banks improved investor sentiment considerably and helped spark rebounds in both commodity prices and global equities. Emerging markets stocks performed particularly well in the subsequent rally, reflecting the many positive developments specific to the asset class. For example, Russia and China both began to experience improving economic growth, while the impeachment of Brazil's President Dilma Rousseff fueled hopes for market-oriented reforms in that country. In addition, an improvement in corporate profits provided a new pillar of support for equity returns, following the subpar earnings results of recent years. Together, these factors helped emerging markets stocks finish the 12-month period with a strong total return of 8.47%, as measured by the MSCI Index. Q Which of your investment decisions had the greatest effect on the Fund's benchmark-relative performance during the 12-month period ended November 30, 2016? A In managing the Fund, we use a bottom-up approach that seeks to identify the most compelling stock ideas anywhere within the emerging markets investment universe. Rather than constructing the portfolio in a manner that strives to mimic the composition of the MSCI Index benchmark, we focus on finding what we believe to be undervalued companies with unappreciated catalysts for improved performance. As part of the process, we try to find companies with effective corporate governance as well as a strong shareholder focus, traits that are often demonstrated through above-average dividend* payments and stock buybacks. We believe this approach is more prudent than buying stocks of poorly managed or overvalued companies simply because they might be components of the Fund's benchmark. Our investment strategy served the Fund well from a total-return perspective over the last 12 months, as falling bond yields prompted investors to rotate toward stocks with higher dividends. In turn, the markets began to reward companies with robust corporate governance practices. * Dividends are not guaranteed. Pioneer Emerging Markets Fund | Annual Report | 11/30/16 5 Relative to the benchmark, however, the Fund underperformed, as the portfolio's investments lost some ground through stock selection results in both information technology and industrials. With regard to individual holdings, shares of ChinaCache, which provides technology that allows cities to manage traffic via "congestion charges" on drivers, detracted the most from the Fund's benchmark-relative performance during the period. The company missed earnings, causing the stock to lag in the strong market for emerging markets equities. The Fund's benchmark-relative returns also lost ground due to an investment in the Brazilian auto parts manufacturer Tupy, whose position in the supply chain of large U.S. auto producers made it vulnerable to possible shifts in U.S. trade policy. We view the situation as a short-term concern, though, as the process of U.S. companies bringing outsourced functions back onshore is a more difficult proposition than Tupy's market performance would indicate. We therefore continued to hold the stock in the portfolio as of period end. Our stock selection process produced the most positive benchmark-relative results for the Fund in the banking, materials, and consumer sectors. The portfolio holding that made the largest contribution to the Fund's benchmark-relative performance during the period was Eurobank Ergasias, a Greek bank that benefited from structural improvements in that country's financial system. Management provided investors with positive guidance, highlighting the bank's declining cost of capital and potentially improving net interest margins. Another positive contributor to the Fund's benchmark-relative performance was a position in Global Telecom Holding, an Egyptian provider of information technology and mobile telecommunications services. The company cut costs, shored up its balance sheet, and continued to address certain governance issues, which led to a recovery in investor sentiment toward the stock. In China, the Fund's position in Goodbaby International, which manufactures strollers, car seats, and other child safety products, was another notable contributor to benchmark-relative results. We originally purchased the shares on the belief that the company was uniquely positioned to capitalize on growing middle-class wealth in China. This has indeed proven to be the case. Meanwhile, Goodbaby's stock price has received a further boost because the 6 Pioneer Emerging Markets Fund | Annual Report | 11/30/16 company has demonstrated an increased shareholder focus through better management, clearer controls, and stronger progress on governance as compared with its peers. Q Did you invest in any derivatives while managing the Fund during the 12-month period ended November 30, 2016? If so, did the derivative positions have any effect on the Fund's performance? A We used derivatives in the form of foreign forward currency contracts in order to help manage the Fund's overall risk and volatility profile. Our strategy sought to provide the portfolio with exposure to currencies on which we had a positive outlook, such as Brazil's, and to hedge existing equity positions in the Fund, as was the case with the currencies of Korea and Taiwan. We also used derivatives to hedge currency risk in Nigeria. While we saw an opportunity in Nigerian banks, we sought to hedge the Fund's exposure to the country's currency (the naira) given the weakness in oil prices over the early months of the period. Overall, the hedging strategy on the Nigerian currency contributed to the Fund's benchmark-relative performance, as the Nigerian government elected to devalue the nation's currency in June. The other derivative positions we employed did not have a material effect on the Fund's performance. Q Do you have any closing thoughts for investors? A Our investment approach in managing the Fund can lead to swings in short-term performance relative to the benchmark MSCI Index, and that indeed proved to be the case over the past 12 months. However, we see significant value in our preference for owning shares of undervalued companies that we believe can generate sustainable results through effective execution, strong management, and return of capital to shareholders. While macroeconomic developments and news headlines will always play a role in the quarter-to-quarter performance of emerging markets equities, we believe the company-specific factors on which we focus can help form the foundation for longer-term returns at the individual security level.

All results are historical and assume the reinvestment of dividends and capital gains. Other share classes are available for which performance and expenses will differ. Performance results reflect any applicable expense waivers in effect during the periods shown. Without such waivers Fund performance would be lower. Waivers may not be in effect for all funds. Certain fee waivers are contractual through a specified period. Otherwise, fee waivers can be rescinded at any time. See the prospectus and financial statements for more information. The performance table and graph do not reflect the deduction of fees and taxes that a shareowner would pay on Fund distributions or the redemption of Fund shares. Please refer to the financial highlights for a more current expense ratio. 14 Pioneer Emerging Markets Fund | Annual Report | 11/30/16 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 Fund Based on actual returns from June 1, 2016 through November 30, 2016. -------------------------------------------------------------------------------- Share Class A C R Y -------------------------------------------------------------------------------- Beginning Account Value $1,000.00 $1,000.00 $1,000.00 $1,000.00 on 6/1/16 -------------------------------------------------------------------------------- Ending Account Value $1,000.66 $ 996.97 $1,000.00 $1,002.26 (after expenses) on 11/30/16 -------------------------------------------------------------------------------- Expenses Paid $ 9.75 $ 14.23 $ 11.00 $ 8.81 During Period* -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized net expense ratio of 1.95%, 2.85%, 2.20% and 1.76% for Class A, Class C, Class R and Class Y shares, respectively, multiplied by the average account value over the period, multiplied by 183/366 (to reflect the one-half year period). Pioneer Emerging Markets Fund | Annual Report | 11/30/16 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.

Pioneer Emerging Markets Fund | Annual Report | 11/30/16 31 Notes to Financial Statements | 11/30/16 1. Organization and Significant Accounting Policies Pioneer Emerging Markets Fund (the Fund) is 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 long-term growth of capital. The Fund offers four classes of shares designated as Class A, Class C, Class R, and Class Y shares. Each class of shares represents an interest in the same portfolio of investments of the Fund and has identical rights (based on relative net asset values) to assets and liquidation proceeds. Share classes can bear different rates of class-specific fees and expenses such as transfer agent and distribution fees. Differences in class-specific fees and expenses will result in differences in net investment income and, therefore, the payment of different dividends from net investment income earned by each class. The Amended and Restated Declaration of Trust of the Fund gives the Board of Trustees the flexibility to specify either per-share voting or dollar-weighted voting when submitting matters for shareholder approval. Under per-share voting, each share of a class of the Fund is entitled to one vote. Under dollar-weighted voting, a shareholder's voting power is determined not by the number of shares owned, but by the dollar value of the shares on the record date. Each share class has exclusive voting rights with respect to matters affecting only that class, including with respect to the distribution plan for that class. There is no distribution plan for Class Y shares. The Fund's financial statements have been prepared in conformity with U.S. generally accepted accounting principles (U.S. GAAP) that require the management of the Fund to 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 Fund is an investment company and follows investment company accounting and reporting guidance under U.S. GAAP. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements: A. Security Valuation 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. 32 Pioneer Emerging Markets Fund | Annual Report | 11/30/16 Equity securities that have traded on an exchange are valued by using 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 or, if both last bid and asked prices are not available, at the last quoted bid price. Last sale and bid and asked prices are provided by independent third party pricing services. In the case of equity securities not traded on an exchange, prices are typically determined by independent third party pricing services using a variety of techniques and methods. The principal exchanges and markets for non-U.S. equity securities have closing times prior to the close of the NYSE. However, the value of these securities may be influenced by changes in global markets occurring after the closing times of the local exchanges and markets up to the time the Fund determines its net asset value. Consequently, the Fund uses a fair value model developed by an independent pricing service to value non-U.S. equity securities. On a daily basis, the pricing service recommends changes, based on a proprietary model, to the closing market prices of each non-U.S. security held by the Fund to reflect the security's fair value at the time the Fund determines its net asset value. The Fund applies these recommendations in accordance with procedures approved by the Board of Trustees. Fixed-income securities are valued by using 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, or may use a pricing matrix or other fair value methods or techniques to provide an estimated value of the security or instrument. A pricing matrix is a means of valuing a debt security on the basis of current market prices for other debt securities, historical trading patterns in the market for fixed-income securities and/or other factors. Non-U.S. debt securities that are listed on an exchange will be valued at the bid price obtained from an independent third party pricing service. When independent third party pricing services are unable to supply prices, or when prices or market quotations are considered to be unreliable, the value of that security may be determined using quotations from one or more broker-dealers. Futures contracts are generally valued at the closing settlement price established by the exchange on which they are traded. Forward foreign currency exchange contracts are valued daily using the foreign exchange rate or, for longer term forward contract positions, the spot currency rate and the forward points on a daily basis, in each case provided by a third party pricing service. Contracts whose forward settlement date falls between two quoted days are valued by interpolation. Pioneer Emerging Markets Fund | Annual Report | 11/30/16 33 Securities for which independent pricing services or broker-dealers 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 and a wholly owned indirect subsidiary of UniCredit S.p.A. (UniCredit), pursuant to procedures adopted by the 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. At November 30, 2016, two securities were valued using fair value methods (in addition to securities valued using prices supplied by independent pricing services) representing 0.04% of net assets. B. Investment Income and Transactions 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. Security transactions are recorded as of trade date. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. C. Foreign Currency Translation The books and records of the Fund are maintained in U.S. dollars. Amounts denominated in foreign currencies are translated into U.S. dollars using current exchange rates. 34 Pioneer Emerging Markets Fund | Annual Report | 11/30/16 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 price of those securities but are included with the net realized and unrealized gain or loss on investments. D. Forward Foreign Currency Contracts The Fund may enter into forward foreign currency contracts (contracts) for the purchase or sale of a specific foreign currency at a fixed price on a future date. All contracts are marked to market daily at the applicable exchange rates, and any resulting unrealized appreciation or depreciation is recorded in the Fund's financial statements. The Fund records realized gains and losses at the time a 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 5). E. 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 due to the broker as collateral at November 30, 2016 was $347,311 and is recorded within "Restricted Cash" on the Statement of Assets and Liabilities. Subsequent payments for futures contracts ("variation margin") are paid or received by the Fund, depending on the daily fluctuation in the value of the contracts, and are recorded by the Fund as unrealized gains or losses. When the contract is closed, the Fund realizes a gain or loss equal to the difference between the opening and closing value of the contract as well as any fluctuation in foreign currency exchange rates where applicable. The use of futures contracts involves, to varying degrees, elements of market, interest rate, currency exchange rate and counterparty risks, which may exceed the amounts recognized by the Fund. Changes in value of the contracts may not directly correlate to the changes in value of the underlying securities. The average value of contracts open for the year ended November 30, 2016 was $2,027,568. Pioneer Emerging Markets Fund | Annual Report | 11/30/16 35 At November 30, 2016, open futures contracts were as follows: ------------------------------------------------------------------------------------ Number of Net Unrealized Contracts Settlement Appreciation Description Counterparty Long/(Short) Month Value (Depreciation) ------------------------------------------------------------------------------------ MSCI Taiwan Index UBS AG 30 12/16 $1,035,300 $ 6,301 KOS P12- Index UBS AG 19 3/17 2,027,433 (1,618) ------------------------------------------------------------------------------------- Total $3,062,733 $ 4,683 ===================================================================================== F. Federal Income Taxes It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its net taxable income and net realized capital gains, if any, to its shareowners. Therefore, no provision for federal income taxes is required. As of November 30, 2016, 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 are subject to examination by Federal and State tax authorities. In determining the daily net asset value, the Fund estimates the reserve for the repatriation of taxes, if any, associated with its investments in certain countries. The estimated reserve for 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 carryforwards (if applicable) and other such factors. As of November 30, 2016, the Fund had accrued $106,796 in reserve for repatriation taxes 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. GAAP. Distributions in excess of net investment income or net realized gains are temporary overdistributions for financial statement purposes resulting from differences in the recognition or classification of income or distributions for financial statement and tax purposes. Capital accounts within the financial statements are adjusted for permanent book/tax differences to reflect tax character, but are not adjusted for temporary differences. At November 30, 2016, the Fund reclassified $1,206,016 to decrease paid-in capital, $690,286 to increase distributions in excess of net investment income and $1,896,302 to decrease accumulated net realized loss on investments, futures contracts and foreign currency transactions to reflect permanent book/tax differences. These adjustments have no impact on net assets or the results of operations. 36 Pioneer Emerging Markets Fund | Annual Report | 11/30/16 At November 30, 2016, the Fund was permitted to carry forward indefinitely $16,287,651 of short-term losses and $13,511,193 of long-term losses under the Regulated Investment Company Modernization Act of 2010, without limitation. The Fund has elected to defer $213,706 of currency losses recognized between December 1, 2015 and November 30, 2016 to its fiscal year ending November 30, 2017. The tax character of distributions paid during the fiscal years ended November 30, 2016 and November 30, 2015 were as follows: ------------------------------------------------------------------------------------ 2016 2015 ------------------------------------------------------------------------------------ Distribution paid from: Ordinary income $3,568,763 $3,483,745 Long-term capital gain -- 2,295,646 ------------------------------------------------------------------------------------ Total $3,568,763 $5,779,391 ==================================================================================== The following shows the components of distributable earnings on a federal income tax basis at November 30, 2016: ------------------------------------------------------------------------------------ 2016 ------------------------------------------------------------------------------------ Distributable earnings: Capital loss carryforward $(29,798,844) Current year late year currency loss (213,706) Net unrealized depreciation (18,063,518) ------------------------------------------------------------------------------------ Total $(48,076,068) ==================================================================================== The difference between book-basis and tax-basis net unrealized depreciation is attributable to the tax deferral of losses on wash sales and the mark to market of forward currency contracts. G. 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, earned $8,487 in underwriting commissions on the sale of Class A shares during the year ended November 30, 2016. H. 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. Pioneer Emerging Markets Fund | Annual Report | 11/30/16 37 Distribution fees are calculated based on the average daily net asset value attributable to Class A, Class C and Class R shares of the Fund, respectively (see Note 4). Class Y shares do not pay distribution fees. All expenses and fees paid to the Fund's transfer agent for its services are allocated among the classes of shares based on the number of accounts in each class and the ratable allocation of related out-of-pocket expenses (see Note 3). 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, Class R and Class Y shares can reflect different transfer agent and distribution expense rates. I. Risks The value of securities held by the fund may go up or down, sometimes rapidly or unpredictably, due to general market conditions, such as real or perceived adverse economic, political or regulatory conditions, inflation, changes in interest rates, lack of liquidity in the bond markets or adverse investor sentiment. In the past several years, financial markets have experienced increased volatility, depressed valuations, decreased liquidity and heightened uncertainty. These conditions may continue, recur, worsen or spread. The Fund's investments in emerging markets or countries with limited or developing markets may subject the Fund to a greater degree of risk than investments in a developed market. Risks associated with these developing markets include political, social and economic factors and may affect the price of the Fund's investments and income generated by these investments, as well as the Fund's ability to repatriate such amounts. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making the Fund more susceptible to any economic, political or regulatory developments or other risks affecting those industries and sectors. The Fund's prospectus contains unaudited information regarding the Fund's principal risks. Please refer to that document when considering the Fund's principal risks. 2. Management Agreement PIM manages the Fund's portfolio. Management fees are calculated daily at an annual rate equal to 1.10% of the Fund's average daily net assets up to $1 billion and 1.05% on assets over $1 billion. For the year ended November 30, 2016, the effective management fee (excluding waivers and/or assumption of expenses) was 1.10% of the Fund's average daily net assets. 38 Pioneer Emerging Markets Fund | Annual Report | 11/30/16 PIM has contractually agreed to limit ordinary operating expenses to the extent required to reduce Fund expenses to 1.95%, 2.85% and 2.20% of the average daily net assets attributable to Class A, Class C and Class R shares, respectively. These expense limitations are in effect through April 1, 2018. There can be no assurance that PIM will extend the expense limitation agreement for a class of shares beyond the date referred to above. Fees waived and expenses reimbursed during the year ended November 30, 2016 are reflected on the Statement of Operations. Class Y shares do not have an expense limitation. 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 $6,264 in management fees, administrative costs and certain other reimbursements payable to PIM at November 30, 2016. 3. Transfer Agent Boston Financial Data Services, Inc. serves as the transfer agent to the Fund at negotiated rates. Transfer agent fees and payables shown on the Statement of Operations and the Statement of Assets and Liabilities, respectively, include sub-transfer agent expenses incurred through the Fund's omnibus relationship contracts. In addition, the Fund reimbursed the transfer agent for out-of-pocket expenses incurred by the transfer agent related to shareholder communications activities such as proxy and statement mailings and outgoing phone calls. For the year ended November 30, 2016, such out-of-pocket expenses by class of shares were as follows: -------------------------------------------------------------------------------- Shareholder Communications: -------------------------------------------------------------------------------- Class A $179,359 Class C 35,762 Class R 53,322 Class Y 4,699 -------------------------------------------------------------------------------- Total $273,142 ================================================================================ 4. Distribution and Service Plans The Fund has adopted a Distribution Plan (the Plan) pursuant to Rule 12b-1 of the Investment Company Act of 1940 with respect to its Class A, Class C and Class R shares. Pursuant to the Plan, the Fund pays PFD 0.25% of the average daily net assets attributable to Class A shares as compensation for personal services and/or account maintenance services or distribution services with regard to Class A shares. Pursuant to the Plan, the Fund also pays PFD 1.00% of the average daily net assets attributable to Class C shares. The fee for Class C shares consists of a 0.25% service fee and a 0.75% distribution fee paid as Pioneer Emerging Markets Fund | Annual Report | 11/30/16 39 compensation for personal services and/or account maintenance services or distribution services with regard to Class C shares. Pursuant to the Plan, the Fund further pays PFD 0.50% of the average daily net assets attributable to Class R shares for distribution services. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $2,076 in distribution fees payable to PFD at November 30, 2016. The Fund also has adopted a separate service plan for Class R shares (Service Plan). The Service Plan authorizes the Fund to pay securities dealers, plan administrators or other service organizations that agree to provide certain services to retirement plans or plan participants holding shares of the Fund a service fee of up to 0.25% of the Fund's average daily net assets attributable to Class R shares held by such plans. In addition, redemptions of each class of shares (except Class R and Class Y shares) may be subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may be imposed on redemptions of certain net asset value purchases of Class A shares within 12 months of purchase. Redemptions of Class C shares within 12 months of purchase are subject to a CDSC of 1.00%, based on the lower of cost or market value of shares being redeemed. Shares purchased as part of an exchange remain subject to any CDSC that applied to the original purchase of those shares. There is no CDSC for Class R or Class Y shares. Proceeds from the CDSCs are paid to PFD. For the year ended November 30, 2016, CDSCs in the amount of $812 were paid to PFD. 5. Forward Foreign Currency Contracts At November 30, 2016, the Fund had entered into various forward foreign currency contracts that obligate the Fund to deliver or take delivery of currencies at specified future maturity dates. Alternatively, prior to the settlement date of a forward foreign currency contract, the Fund may close out such contract by entering into an offsetting contract. The average value of forward foreign currency contracts open during the year ended November 30, 2016 was $3,203,772. Open forward foreign currency contracts at November 30, 2016 were as follows: ---------------------------------------------------------------------------------------------------- In Currency Currency Exchange Settlement Unrealized Sold Deliver Purchased for Counterparty Date Appreciation ---------------------------------------------------------------------------------------------------- BRL (20,830,693) USD 6,375,645 Goldman Sachs & Co. 1/17/2017 $ 314,749 MXN (38,537,596) USD 1,906,447 Goldman Sachs & Co. 1/19/2017 40,825 USD (3,364,584) ZAR 48,018,757 Goldman Sachs & Co. 1/19/2017 10,155 KRW (2,357,272,202) USD 2,048,926 Goldman Sachs & Co. 1/17/2017 46,324 ---------------------------------------------------------------------------------------------------- Total $ 412,053 ==================================================================================================== 40 Pioneer Emerging Markets Fund | Annual Report | 11/30/16 ------------------------------------------------------------------------------------------------------- In Currency Currency Exchange Settlement Unrealized Sold Deliver Purchased for Counterparty Date Depreciation ------------------------------------------------------------------------------------------------------- USD (3,551,577) KRW 4,000,000,000 Goldman Sachs & Co. 1/17/2017 $(153,409) USD (1,667,298) IDR 22,000,000,000 Goldman Sachs & Co. 1/17/2017 (55,777) USD (3,594,148) TWD 113,000,000 Morgan Stanley Co. 1/19/2017 (50,573) NGN (918,969,901) USD 2,565,111 Goldman Sachs & Co. 1/17/2017 (200,650) USD (2,631,073) MXN 49,729,884 Goldman Sachs & Co. 1/19/2017 (223,627) USD (2,960,112) INR 200,000,000 Morgan Stanley Co. 1/19/2017 (59,231) USD (1,902,271) MYR 8,000,000 Barclays Plc 1/19/2017 (114,194) NGN (501,648,366) USD 1,397,349 Barclays Plc 1/19/2017 (112,427) -------------------------------------------------------------------------------------------------------- Total $(969,888) ======================================================================================================== BRL - Brazilian Real MYR - Malaysian Ringgit IDR - Indonesian Rupiah NGN - Nigerian Naira INR - Indian Rupee TWD - New Taiwan Dollar KRW - South Korean Won ZAR - South African Rand MXN - Mexican Peso 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 9, 2016, was in the amount of $240 million. Effective February 10, 2016, the facility is in the amount of $220 million. Under such facility, depending on the type of loan, interest on borrowings is payable at the London Interbank Offered Rate (LIBOR) plus 0.85% on an annualized basis, or the Alternate Base Rate, which is the greater of (a) the facility's administrative agent's daily announced prime rate on the borrowing date, (b) 2% plus the Federal Funds Rate on the borrowing date and (c) 2% plus the overnight Eurodollar rate on the borrowing date. The Funds pay an annual commitment fee to participate in a credit facility. The commitment fee is allocated among participating Funds based on an allocation schedule set forth in the credit agreement. For the year ended November 30, 2016, the Fund had no borrowings under the credit facility. 7. Assets and Liabilities Offsetting The Fund has entered into an International Swaps and Derivatives Association, Inc. Master Agreement ("ISDA Master Agreement") or similar agreement with substantially all its derivative counterparties. An ISDA Master Agreement is a bilateral agreement between the Fund and a counterparty that governs the trading of certain OTC derivatives and typically contains, among other things, close-out and set-off provisions which apply upon the occurrence of event of a default and/or termination event as defined under the relevant ISDA Master Agreement. The ISDA Master Agreement may also give a party the right to terminate all transactions traded under such agreement if, among other things, Pioneer Emerging Markets Fund | Annual Report | 11/30/16 41 there is deterioration in the credit quality of the other party. Upon an event of default or a termination of the ISDA Master Agreement, the non-defaulting party has the right to close out all transactions under such agreement and to net amounts owed under each transaction to determine one net amount payable by one party to the other. The right to close out and net payments across all transactions under the ISDA Master Agreement could result in a reduction of the Fund's credit risk to its counterparty equal to any amounts payable by the Fund under the applicable transactions, if any. However, the Fund's right to setoff may be restricted or prohibited by the bankruptcy or insolvency laws of the particular jurisdiction to which each specific ISDA of each counterparty is subject. The collateral requirements for derivatives transactions under an ISDA Master Agreement are governed by a credit support annex to the ISDA Master Agreement. Collateral requirements are generally determined at the close of business each day and are typically based on changes in market values for each transaction under an ISDA Master Agreement and netted into one amount for such agreement. Generally, the amount of collateral due from or to a counterparty is subject to threshold (a "minimum transfer amount") before a transfer is required, which may vary by counterparty. Collateral pledged for the benefit of the Fund and/or counterparty is held in segregated accounts by the Fund's custodian and cannot be sold, re-pledged, assigned or otherwise used while pledged. Cash that has been segregated to cover the Fund's collateral obligations, if any, will be reported separately in the Statement of Assets and Liabilities as "Restricted Cash." Securities pledged by the Fund as collateral, if any, are identified as such in the Schedule of Investments. Financial instruments subject to an enforceable master netting agreement such as an ISDA Master Agreement have not been offset on the Statement of Assets and Liabilities. The following charts show gross assets and liabilities of the Fund as of November 30, 2016. ------------------------------------------------------------------------------------------------ Derivative Assets Subject to Derivatives Non-Cash Cash Net Amount Master Netting Available Collateral Collateral of Derivative Counterparty Agreement for Offset Received (a) Received (a) Assets (b) ------------------------------------------------------------------------------------------------ Barclays Plc $ -- $ -- $ -- $ -- $ -- Goldman Sachs & Co. 412,053 (412,053) -- -- -- Morgan Stanley Co. -- -- -- -- -- ------------------------------------------------------------------------------------------------ Total $ 412,053 $ (412,053) $ -- $ -- $ -- ================================================================================================ 42 Pioneer Emerging Markets Fund | Annual Report | 11/30/16 ----------------------------------------------------------------------------------------------------- Derivative Liabilities Subject to Derivatives Non-Cash Cash Net Amount Master Netting Available Collateral Collateral of Derivative Counterparty Agreement for Offset Pledged (a) Pledged (a) Liabilities (c) ----------------------------------------------------------------------------------------------------- Barclays Plc $ 226,621 $ -- $ -- $ -- $ 226,621 Goldman Sachs & Co. 633,463 (412,053) -- -- 221,410 Morgan Stanley Co. 109,804 -- -- -- 109,804 ----------------------------------------------------------------------------------------------------- Total $ 969,888 $(412,053) $ -- $ -- $ 557,835 ===================================================================================================== (a) The amount presented here may be less than the total amount of collateral received/pledged as the net amount of derivative assets and liabilities cannot be less than $0. (b) Represents the net amount due from the counterparty in the event of default. (c) Represents the net amount payable to the counterparty in the event of default. 8. Additional Disclosures about Derivative Instruments and Hedging Activities The Fund's use of derivatives may subject it to the following risks: Interest rate risk relates to the fluctuations in the value of interest-bearing securities due to changes in the prevailing levels of market interest rates. Credit risk relates to the ability of the issuer of a financial instrument to make further principal or interest payments on an obligation or commitment that it has to the Fund. Foreign exchange rate risk relates to fluctuations in the value of an asset or liability due to changes in currency exchange rates. Equity risk relates to the fluctuations in the value of financial instruments as a result of changes in market prices (other than those arising from interest rate risk or foreign exchange risk), whether caused by factors specific to an individual investment, its issuer, or all factors affecting all instruments traded in a market or market segment. Commodity risk relates to the risk that the value of a commodity or commodity index will fluctuate based on increases or decreases in the commodities market and factors specific to a particular industry or commodity. Pioneer Emerging Markets Fund | Annual Report | 11/30/16 43 The fair value of open derivative instruments (not considered to be hedging instruments for accounting disclosure purposes) by risk exposure at November 30, 2016 was as follows: Statement of Assets and Liabilities ------------------------------------------------------------------------------------ Foreign Interest Credit Exchange Equity Commodity Rate Risk Risk Rate Risk Risk Risk ------------------------------------------------------------------------------------ Assets Unrealized appreciation of forward foreign currency contracts $ -- $ -- $ 412,053 $ -- $ -- Unrealized appreciation of futures contracts* -- 6,301 -- -- -- ------------------------------------------------------------------------------------ Total Value $ -- $ 6,301 $ 412,053 $ -- $ -- ==================================================================================== Liabilities Unrealized depreciation of forward foreign currency contracts $ -- $ -- $ 969,888 $ -- $ -- Unrealized depreciation of futures contracts* -- 1,618 -- -- -- ------------------------------------------------------------------------------------ Total Value $ -- $ 1,618 $ 969,888 $ -- $ -- ==================================================================================== * Reflects unrealized appreciation/depreciation of futures contracts (see Note 1E).

These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. The financial highlights for the years ended November 30, 2013, and 2012, were audited by other auditors. Those auditors expressed an unqualified opinion on those financial statements and financial highlights in their report dated January 24, 2014. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of November 30, 2016, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Pioneer Emerging Markets Fund as of November 30, 2016, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the three years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. /s/ Deloitte & Touche LLP Boston, Massachusetts January 25, 2017 Pioneer Emerging Markets Fund | Annual Report | 11/30/16 45 ADDITIONAL INFORMATION (unaudited) Pioneer Investment Management, Inc. (the "Adviser"), the Fund's investment adviser, is currently an indirect, wholly owned subsidiary of UniCredit S.p.A. ("UniCredit"). On December 12, 2016, UniCredit announced that it has entered into a binding agreement for the sale of its Pioneer Investments business, which includes the Adviser, to Amundi (the "Transaction"). Amundi is headquartered in Paris, France, and, as of September 30, 2016, had more than $1.1 trillion in assets under management worldwide. The closing of the Transaction is expected to happen in 2017, subject to certain regulatory and antitrust approvals, and other conditions. Under the Investment Company Act of 1940, the closing of the Transaction will cause the Fund's current investment advisory agreement with the Adviser to terminate. Accordingly, the Fund's Board of Trustees will be asked to approve a new investment advisory agreement for the Fund. If approved by the Board, the Fund's new investment advisory agreement will be submitted to the shareholders of the Fund for their approval. 46 Pioneer Emerging Markets Fund | Annual Report | 11/30/16 Approval of Investment Advisory Agreement Pioneer Investment Management, Inc. (PIM) serves as the investment adviser to Pioneer Emerging Markets Fund (the Fund) pursuant to an investment advisory agreement between PIM and the Fund. In order for PIM to remain the investment adviser of the Fund, the Trustees of the Fund must determine annually whether to renew the investment advisory agreement for the Fund. The contract review process began in January 2016 as the Trustees of the Fund agreed on, among other things, an overall approach and timeline for the process. Contract review materials were provided to the Trustees in March 2016 and May 2016. In addition, the Trustees reviewed and discussed the Fund's performance at regularly scheduled meetings throughout the year and took into account other information related to the Fund provided to the Trustees at regularly scheduled meetings in connection with the review of the Fund's investment advisory agreement. In March 2016, the Trustees, among other things, discussed the memorandum provided by Fund counsel that summarized the legal standards and other considerations that are relevant to the Trustees in their deliberations regarding the renewal of the investment advisory agreement, and reviewed and discussed the qualifications of the investment management teams, as well as the level of investment by the Fund's portfolio managers in the Fund. In May 2016, the Trustees, among other things, reviewed the Fund's management fee and total expense ratios, the financial statements of PIM and its parent companies, the profitability analyses provided by PIM, and possible economies of scale. The Trustees also reviewed the profitability of the institutional business of PIM and PIM's affiliate, Pioneer Institutional Asset Management, Inc. (together with PIM, "Pioneer"), as compared to that of PIM's fund management business, and considered the differences between the fees and expenses of the Fund and the fees and expenses of Pioneer's institutional accounts, as well as the different services provided by PIM to the Fund and by Pioneer to the institutional accounts. The Trustees further considered contract review materials in July and September 2016. At a meeting held on September 13, 2016, based on their evaluation of the information provided by PIM and third parties, the Trustees of the Fund, including the Independent Trustees voting separately, unanimously approved the renewal of the investment advisory agreement for another year. In approving the renewal of the investment advisory agreement, the Trustees considered various factors that they determined were relevant, including the factors described below. The Trustees did not identify any single factor as the controlling factor in determining to approve the renewal of the agreement. Pioneer Emerging Markets Fund | Annual Report | 11/30/16 47 Nature, Extent and Quality of Services The Trustees considered the nature, extent and quality of the services that had been provided by PIM to the Fund, taking into account the investment objective and strategy of the Fund. The Trustees also reviewed PIM's investment approach for the Fund and its research process. The Trustees considered the resources of PIM and the personnel of PIM who provide investment management services to the Fund. They also reviewed the amount of non-Fund assets managed by the portfolio managers of the Fund. The Trustees considered the non-investment resources and personnel of PIM involved in PIM's services to the Fund, including PIM's compliance and legal resources and personnel. The Trustees noted the substantial attention and high priority given by PIM's senior management to the Pioneer fund complex. The Trustees considered that PIM supervises and monitors the performance of the Fund's service providers and provides the Fund with personnel (including Fund officers) and other resources that are necessary for the Fund's business management and operations. The Trustees also considered that, as administrator, PIM is responsible for the administration of the Fund's business and other affairs. The Trustees considered the fees paid to PIM for the provision of administration services. Based on these considerations, the Trustees concluded that the nature, extent and quality of services that had been provided by PIM to the Fund were satisfactory and consistent with the terms of the investment advisory agreement. Performance of the Fund In considering the Fund's performance, the Trustees regularly review and discuss throughout the year data prepared by PIM and information comparing the Fund's performance with the performance of its peer group of funds as classified by each of Morningstar, Inc. (Morningstar) and Lipper, and with the performance of the Fund's benchmark index. They discussed the Fund's performance with PIM on a more frequent basis in light of the Fund's unfavorable performance compared to its benchmark index and peers over certain periods. The Trustees noted PIM's explanation for the Fund's relative performance and the steps taken by PIM to address the Fund's performance, including increasing the diversification of the Fund's portfolio, investing in larger capitalization companies and reducing the Fund's tracking error relative to its benchmark. It also was noted that the Fund's recent performance was improved relative to its peer group. The Trustees' reviews and discussions, including the steps taken by PIM to address the Fund's performance, were factored into the Trustees' deliberations concerning the renewal of the advisory agreement. 48 Pioneer Emerging Markets Fund | Annual Report | 11/30/16 Management Fee and Expenses The Trustees considered information showing the fees and expenses of the Fund in comparison to the management fees and expense ratios of its peer group of funds as classified by Morningstar and also to the expense ratios of a peer group of funds selected on the basis of criteria determined by the Independent Trustees for this purpose using data provided by Strategic Insight Mutual Fund Research and Consulting, LLC (Strategic Insight), an independent third party. In all quintile rankings referred to below, first quintile is most favorable to the Fund's shareowners. The Trustees considered that the Fund's management fee for the most recent fiscal year was in the third quintile relative to the management fees paid by other funds in its Morningstar peer group for the comparable period. The Trustees also considered the breakpoint in the management fee schedule and the reduced fee rate above a certain asset level. The Trustees considered that the expense ratio of the Fund's Class A shares for the most recent fiscal year was in the fifth quintile relative to its Morningstar peer group and in the fifth 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 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 and that the results of the most recent such review were considered in the consideration of the Fund's expense ratio. The Trustees reviewed management fees charged by Pioneer to institutional and other clients, including publicly offered European funds sponsored by affiliates of Pioneer, unaffiliated U.S. registered investment companies (in a sub-advisory capacity), and unaffiliated foreign and domestic separate accounts. The Trustees also considered PIM's costs in providing services to the Fund and Pioneer's costs in providing services to the other clients and considered the differences in management fees and profit margins for Fund and non-Fund services. In evaluating the fees associated with Pioneer's client accounts, the Trustees took into account the respective demands, resources and complexity associated with the Fund and client accounts. The Trustees noted that, in some instances, the fee rates for those clients were lower than the management fee for the Fund and considered that, under the investment advisory agreement with the Fund, PIM performs additional services for the Fund that it does not provide to those other clients or services that are broader in scope, including oversight of the Fund's other service providers and Pioneer Emerging Markets Fund | Annual Report | 11/30/16 49 activities related to compliance and the extensive regulatory and tax regimes to which the Fund is subject. The Trustees also considered the different entrepreneurial risks associated with PIM's management of the Fund and Pioneer's management of the other client accounts. The Trustees concluded that the management fee payable by the Fund to PIM was reasonable in relation to the nature and quality of the services provided by PIM to the Fund. Profitability The Trustees considered information provided by PIM regarding the profitability of PIM with respect to the advisory services provided by PIM to the Fund, including the methodology used by PIM in allocating certain of its costs to the management of the Fund. The Trustees also considered PIM's profit margin in connection with the overall operation of the Fund. They further reviewed the financial results, including the profit margins, 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 breakpoint in the management fee schedule. The Trustees recognize that economies of scale are difficult to identify and quantify, and that, among other factors that may be relevant, are the following: fee levels, expense subsidization, investment by PIM in research and analytical capabilities and PIM's commitment and resource allocation to the Fund. The Trustees noted that profitability also may be an indicator of the availability of any economies of scale, although profitability may vary for other reasons including reductions in expenses. The Trustees concluded that economies of scale, if any, were being appropriately shared with the Funds. Other Benefits The Trustees considered the other benefits to PIM from its relationship with the Fund. The Trustees considered the character and amount of fees paid by the Fund, other than under the investment advisory agreement, for services provided by PIM and its affiliates. The Trustees further considered the revenues and profitability of PIM's businesses other than the fund business. 50 Pioneer Emerging Markets Fund | Annual Report | 11/30/16 Pioneer is the principal U.S. asset management business of Pioneer Global Asset Management, the worldwide asset management business of UniCredit Group, which manages over $150 billion in assets (including the Funds). Pioneer and the Funds receive reciprocal intangible benefits from the relationship, including mutual brand recognition and, for the Funds, direct and indirect access to the resources of a large global asset manager. The Trustees concluded that any such benefits received by Pioneer as a result of its relationship with the Funds were reasonable and their consideration of the advisory agreement between the Fund and PIM and the fees thereunder were unaffected by Pioneer's possible receipt of any such intangible benefits. Conclusion After consideration of the factors described above as well as other factors, the Trustees, including all of the Independent Trustees, concluded that the investment advisory agreement between PIM and the Fund, including the fees payable thereunder, was fair and reasonable and voted to approve the proposed renewal of the investment advisory agreement for the Fund.

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.
