We have been cautiously optimistic about the U.S. from the start of the year, and the economic data continue to be encouraging. The housing and auto sectors are benefitting from record-low interest rates. The climate for consumer and business credit has improved, and inflation appears to be subdued. While corporate profits slowed in the third quarter, many U.S. companies continue to have strong balance sheets and to pay attractive dividends* compared to fixed-income securities. All of these factors contributed to gains for investors who owned riskier assets, including equities and higher-yielding corporate bonds. Year to date through the end of the third quarter, the Standard & Poor's 500 Index returned 16.35%. In fixed income, the Bank of America Merrill Lynch High Yield Master II Index was up by 12.02% during the same period, while the Barclays Capital Aggregate Bond Index gained 3.99%. Treasury bonds, by contrast, generated a comparatively sluggish return of 1.70%, as measured by the Barclays Capital Intermediate Treasuries Index. Despite this generally positive picture during the first three quarters of 2012, investors face powerful macroeconomic challenges in the months ahead. These include the threat of a so-called "fiscal cliff" in the U.S. budget process after the November elections, the European sovereign-debt crisis, and slowing growth in both Europe and China. Investors can continue to count on market volatility tied to these factors, although we remain optimistic that the underlying economic trends are moving in the right direction. At Pioneer, we have long advocated the benefits of staying diversified** and investing for the long term. And while diversification alone does not assure a profit or protect against loss in a declining market, we believe in actively seeking out opportunities in undervalued securities and sectors around the globe. Our advice, as always, is to work closely with a trusted financial advisor to discuss your goals and work together to develop an investment strategy that meets your individual needs. There is no single best strategy that works for every investor. * Dividends are not guaranteed. ** Diversification does not assure a profit or protect against loss in a declining market. 2 Pioneer Emerging Markets Fund | Annual Report | 11/30/12 Pioneer's investment professionals focus on finding good opportunities in both equity and bond markets using the same disciplined investment approach we have used since 1928.

Pioneer Emerging Markets Fund | Annual Report | 11/30/12 3 Portfolio Management Discussion | 11/30/12 In the following interview, Sean Taylor, head of the global emerging markets equity team and senior vice president at Pioneer, discusses the investment environment for emerging market equities and the performance of Pioneer Emerging Markets Fund during the 12 months ended November 30, 2012. Mr. Taylor assumed responsibility for the daily management of the Fund on December 15, 2011. Q How would you describe the investment environment for emerging market stocks during the 12 months ended November 30, 2012? A Equities in the emerging markets delivered a healthy, double-digit gain during the 12 months ended November 30, 2012, as measured by the Fund's benchmark, the Morgan Stanley Capital International (MSCI) Emerging Markets Index1, which returned 11.73% during the period. The asset class gained ground during the 12-month period as the aggressive monetary stimulus of the world's major central banks led to a substantial improvement in investor sentiment. In addition, the emerging markets continued to feature a wealth of companies generating rapid earnings growth at a time of very sluggish performance for the overall global economy. While strong on an absolute basis, the return of the emerging markets during the 12-month period lagged that of the world's developed markets, as measured by the MSCI World Index, which returned 14.31%, and U.S. large-cap stocks, as measured by the Standard & Poor's 500 Index, which returned 16.11%. The primary cause of the emerging markets' underperformance during the 12-month period was slowing growth across the region in general, and in China in particular. Although China's gross domestic product (GDP) growth has remained high (at 7% to 8% per year), current GDP levels represent a substantial decline from the 9% to 14% GDP growth the country's economy experienced from 2003 to 2010. Slower growth in China has had an effect on emerging market stocks worldwide, 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.

Q How did the Fund perform during the 12 months ended November 30, 2012? A Pioneer Emerging Markets Fund's Class A shares returned 1.06% during the 12 months ended November 30, 2012, while the Fund's benchmark, the MSCI Emerging Markets Index (the MSCI Index), returned 11.73%. During the same period, the average return of the 521 mutual funds in Lipper's Emerging Markets Funds category was 8.34%. Q What were the main reasons for the Fund's underperformance of the MSCI Index during the 12 months ended November 30, 2012? A While emerging market equities performed well during the 12-month period, the Fund did not participate in the rally. A key factor in the Fund's underperformance of the broader market during the period was our use of valuation as one of the most important investment criteria for the portfolio, during a time when investors demonstrated a heavy bias in favor of growth stocks. During the period, the gap between the two styles was so large, in fact, that the premium between growth stocks and value stocks moved to its widest level in several years. We believe, however, that the wide gap between growth and value presents an opportunity for a potential mean reversion (return to average price levels) among the many value stocks owned by the Fund. From an attribution standpoint, the primary cause of the Fund's shortfall relative to the MSCI Index during the period was stock selection, particularly among the portfolio's investments in Korea, Taiwan, and China. In Korea, the Fund's relative performance was hurt by positions in three industrial stocks: GS Engineering & Construction, Doosan Heavy Industries & Construction, and Hyundai Heavy Industries. The companies saw slowing business trends due to the weak global economy in general, and in China and Japan in particular. In Taiwan, the Fund's stock picks lagged the MSCI Index in the information technology/telecom services areas, where notable detractors in the portfolio were E Ink, Catcher Technology, and Chunghwa Telecom. The Fund's largest detractor holding in China was Baidu, operator of the country's largest Internet search engine. Although the company continues to report stellar growth, it was pressured by slowing economic growth in the country as well as the general weakness of Chinese stocks during the 12-month period. Pioneer Emerging Markets Fund | Annual Report | 11/30/12 5 Outside of holdings in the three Asian markets previously discussed, the Fund's most significant detractor holdings during the period were IAMGOLD, a Canada-based gold miner whose operations were interrupted by labor disputes in South Africa, and the Brazilian energy giant Petrobras, which saw its profits come under pressure due to government price controls. Sector allocation decisions also hurt the Fund's performance relative to the MSCI Index during the period. Specifically, benchmark-relative returns were hurt by portfolio underweights (below-benchmark weightings) in the financials and telecom services sectors, and overweights to information technology and consumer staples. Q Which investment decisions benefited the Fund's performance the most during the 12 months ended November 30, 2012? A The Fund added value relative to the benchmark through an underweight position in the underperforming materials sector, as well as stock selection results in the consumer staples and consumer discretionary sectors. From a geographical standpoint, the Fund registered its strongest performance in South Africa and Mexico. The Fund's holdings that contributed the most to performance during the period were the Latin American beverage companies Companhia de Bebidas das Americas ("Ambev") and Fomento Economico Mexicano, the Russian energy giant Gazprom, and the South African retail distributor Mr Price. The Fund's position in Taiwan Semiconductor also performed well during the period. The company is one of the largest suppliers to Apple and, therefore, was a beneficiary of the iPhone 5 launch. Q From a country or regional perspective, how was the Fund positioned as of November 30, 2012, and what are your views on those regions? A In Asia, the Fund was overweight in China and Korea as of November 30, 2012. Developments in China have remained equity friendly, with inflation running at 2% and earnings growth improving. In addition, the arrival of a new political leadership team suggests that policy priorities could change for the better, and while GDP growth may stabilize at lower levels than those recorded through 2010, growth in China is still quite strong on an absolute basis. We believe it is possible that the Chinese government may accelerate infrastructure investment as part of its current policy direction, and that would play to our existing investment strategy for the Fund in China. In Korea, we have maintained the portfolio's "smartphone" theme, with holdings in SK Hynix and Samsung Electronics. We also see Russia as a source of potential opportunity. In our view, investors have not paid attention to Russia's strengthening fundamental trends, such as positive credit growth, reform of the energy sector and the decline of the country's balance of payments. Russia represented the fourth- largest geographical allocation in the Fund as of November 30, 2012. 6 Pioneer Emerging Markets Fund | Annual Report | 11/30/12 We think investors who look closely at Russia will find a country with the lowest price-to-earnings (P/E) ratio among all nations represented in the MSCI Emerging Markets Index. One reason for the country's low P/E ratio is investors' persistent pessimism about the Russian government's reform efforts, which seems based on the belief that higher oil revenues will enable the government to "go slow" on implementing reforms. We think that presents an opportunity, given that many Russian companies have been demonstrating rising free cash flows. The energy giant Gazprom is the Fund's largest holding in the country. In Latin America, we remain positive on the outlook for both Mexico and Brazil. In the case of the former, we hold a favorable view on the economy, but bargains in the Mexican stock market have been hard to find. In Brazil, we would like to see increased political clarity, particularly with regard to energy prices, which could be a positive for near-term equity returns. The Fund's largest country-specific underweight is in South Africa, a nation that offers a complex sociopolitical outlook and where equities have been trading at the high end of their historic valuation ranges. In addition, South Africa recently has experienced elevated levels of labor unrest and has been showing signs of an increasingly unfavorable political environment. We believe valuations near historic highs indicate that South African stocks aren't adequately compensating investors for the potential risks involved with putting their money into the country. Q What is your broader view on the emerging markets as we head into 2013? A We continue to take heart from the accommodative monetary policies of some of the world's major central banks. While the central banks' offerings of cheap credit are designed to aid economic growth in the developed world, emerging markets also have benefited from the policies. That can be a double-edged sword, however, since any threat to cheap credit conditions often causes investors to worry about the sustainability of such a catalyst, and that can lead to short-term profit taking. Therefore, we would caution investors that even though we hold a positive long-term view on the emerging markets equity asset class, market volatility may continue. Another potential positive for emerging market stocks is the divergence in available return between fixed-income securities and equities. The massive flow of monies into bonds in recent years has led to a sharp decline in the future return potential of fixed-income securities, and that makes stocks - which offer the combination of earnings growth and dividend yield - more attractive on a relative basis. We expect to see money drawn out of bonds and put into equities as asset allocators turn more positive in their outlook for global economic growth. Pioneer Emerging Markets Fund | Annual Report | 11/30/12 7 From a longer-term standpoint, we believe the underlying fundamentals of the emerging markets remain strong, highlighted by low interest rates, improving corporate governance, and sound fiscal management at the government level. We believe those factors, together with emerging market stocks' robust growth and reasonable valuations, should continue to drive favorable long-term returns, despite periodic short-term volatility.

Current performance may be lower or higher than the performance data quoted. The performance data quoted represents past performance, which is no guarantee of future results. Investment return and principal value will fluctuate, and shares, when redeemed, may be worth more or less than their original cost. The performance shown for Class R shares for the period prior to the commencement of operations of Class R shares on April 1, 2003, is based on the performance of the Fund's Class A shares, reduced to reflect the higher distribution and service fees of Class R shares. For the period beginning April 1, 2003, the actual performance of Class R shares is reflected. The performance of Class R shares does not reflect the 1% CDSC that was in effect prior to July 1, 2004. Class R shares are not subject to sales charges and are available for limited groups of eligible investors, including institutional investors. All results are historical and assume the reinvestment of dividends and capital gains. Other share classes are available for which performance and expenses will differ. Performance results reflect any applicable expense waivers in effect during the periods shown. Without such waivers Fund performance would be lower. Waivers may not be in effect for all funds. Certain fee waivers are contractual through a specified period. Otherwise, fee waivers can be rescinded at any time. See the prospectus and financial statements for more information. The net expense ratio reflects contractual expense limitations currently in effect through April 1, 2014, for Class R shares. There can be no assurance that Pioneer will extend the expense limitations beyond such time. Please 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. 14 Pioneer Emerging Markets Fund | Annual Report | 11/30/12 Performance Update | 11/30/12 Class Y Shares Investment Returns -------------------------------------------------------------------------------- The mountain chart on the right shows the change in value of a $5 million investment made in Pioneer Emerging Markets Fund, compared to that of the Morgan Stanley Capital International (MSCI) Emerging Markets Index.

Pioneer Emerging Markets Fund | Annual Report | 11/30/12 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 Emerging Markets Fund Based on actual returns from June 1, 2012 through November 30, 2012. ---------------------------------------------------------------------------------------------- Share Class A B C R Y ---------------------------------------------------------------------------------------------- Beginning Account Value $1,000.00 $1,000.00 $1,000.00 $1,000.00 $1,000.00 on 6/1/12 ---------------------------------------------------------------------------------------------- Ending Account Value $1,086.32 $1,081.90 $1,082.28 $1,085.51 $1,089.30 (after expenses) on 11/30/12 ---------------------------------------------------------------------------------------------- Expenses Paid $ 10.28 $ 14.94 $ 14.42 $ 11.21 $ 7.36 During Period* ---------------------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized net expense ratio plus the expense ratios of underlying funds. These combined totals were 1.97%, 2.87%, 2.77%, 2.15% and 1.41% for Class A, Class B, Class C, Class R and Class Y shares, respectively. These combined ratios were multiplied by the average account value over the period, and then multiplied by 183/366 (to reflect the one-half year period) to calculate the "Expenses Paid During Period" in the table above. 16 Pioneer Emerging Markets Fund | Annual Report | 11/30/12 Hypothetical Example for Comparison Purposes The table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads), that are charged at the time of the transaction. Therefore, the table below is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher. Expenses Paid on a $1,000 Investment in Pioneer Emerging Markets Fund Based on a hypothetical 5% return per year before expenses, reflecting the period from June 1, 2012 through November 30, 2012. ------------------------------------------------------------------------------------------- Share Class A B C R Y ------------------------------------------------------------------------------------------- Beginning Account Value $1,000.00 $1,000.00 $1,000.00 $1,000.00 $1,000.00 on 6/1/12 ------------------------------------------------------------------------------------------- Ending Account Value $1,015.15 $1,010.65 $1,011.15 $1,014.25 $1,017.95 (after expenses) on 11/30/12 ------------------------------------------------------------------------------------------- Expenses Paid $ 9.92 $ 14.43 $ 13.93 $ 10.83 $ 7.11 During Period* ------------------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized net expense ratio plus the expense ratios of underlying funds. These combined totals were 1.97%, 2.87%, 2.77%, 2.15% and 1.41% for Class A, Class B, Class C, Class R and Class Y shares, respectively. These combined ratios were multiplied by the average account value over the period, and then multiplied by 183/366 (to reflect the one-half year period) to calculate the "Expenses Paid During Period" in the table above.

The accompanying notes are an integral part of these financial statements. Pioneer Emerging Markets Fund | Annual Report | 11/30/12 35 Notes to Financial Statements | 11/30/12 1. Organization and Significant Accounting Policies Pioneer Emerging Markets Fund (the Fund) is a Delaware statutory trust 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 five classes of shares designated as Class A, Class B, Class C, Class R, and Class Y shares. 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. 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 gains and losses 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: 36 Pioneer Emerging Markets Fund | Annual Report | 11/30/12 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. In computing the net asset value, securities that have traded on an exchange are valued using the last sale price on the principal exchange where they are traded. 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 their net asset value. The Fund invests primarily in securities of non-U.S. issuers. The principal exchanges and markets for such 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 Board of Trustees of the Fund has determined that daily adjustments to the valuation of securities of non-U.S. issuers by utilizing an independent pricing service that supplies an appropriate fair value factor is appropriate for the Fund. 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 or at the direction or with the approval of the Valuation Committee using fair value methods pursuant to procedures adopted by the Board of Trustees. The Valuation Committee is comprised of certain members of the Board of Trustees. The Fund may use fair value methods if it is determined that a significant event has occurred after the close of the exchange or market on which the security trades and prior to the determination of the Fund's net asset value. Examples of a significant event might include political or economic news, corporate restructurings, natural disasters, terrorist activity or trading halts. Thus, the valuation of the Fund's securities may differ significantly from exchange prices and such differences could be material. Pioneer Investment Management, Inc. (PIM) 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. Pioneer Emerging Markets Fund | Annual Report | 11/30/12 37 At November 30, 2012, there were three securities valued using fair value methods (in addition to securities that were valued using prices supplied by independent pricing services) representing 0.13% of net assets. Inputs used when applying fair value methods to value a security may include credit ratings, the financial condition of the company, current market conditions and comparable securities. Dividend income is recorded on the ex-dividend date, except that certain dividends from foreign securities where the ex-dividend date may have passed are recorded as soon as the Fund becomes aware of the ex-dividend data in the exercise of reasonable diligence. Interest income, including interest on income-bearing cash accounts, is recorded on the accrual basis. Dividend and interest income are reported net of unrecoverable foreign taxes withheld at the applicable country rates. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. B. Foreign Currency Translation The books and records of the Fund are maintained in U.S. dollars. Amounts denominated in foreign currencies are translated into U.S. dollars using current exchange rates. Net realized gains and losses on foreign currency transactions, if any, represent, among other things, the net realized gains and losses on foreign currency contracts, disposition of foreign currencies and the difference between the amount of income accrued and the U.S. dollars actually received. Further, the effects of changes in foreign currency exchange rates on investments are not segregated in the Statement of Operations from the effects of changes in market price of those securities but are included with the net realized and unrealized gain or loss on investments. C. Forward Foreign Currency Contracts The Fund may enter into forward foreign currency contracts (contracts) for the purchase or sale of a specific foreign currency at a fixed price on a future date. All contracts are marked to market daily at the applicable exchange rates, and any resulting unrealized gains or losses are recorded in the Fund's financial statements. The Fund records realized gains and losses at the time a portfolio hedge is offset by entry into a closing transaction or extinguished by delivery of the currency. Risks may arise upon entering into these contracts from the potential inability of counterparties to meet the terms of the contract and from unanticipated movements in the value of foreign currencies relative to the U.S. dollar (see Note 6). 38 Pioneer Emerging Markets Fund | Annual Report | 11/30/12 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 November 30, 2012, the Fund did not have any interest and penalties related to uncertain tax positions, which, if applicable, would be recorded as an income tax expense in the Statement of Operations. Tax years for the prior three fiscal 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 year ended November 30, 2012, the Fund paid no 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 November 30, 2012, the Fund had no 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. At November 30, 2012, the Fund reclassified $329,337 to decrease undistributed net investment income and $329,337 to decrease accumulated net realized loss on investments to reflect permanent book/tax differences. These adjustments have no impact on net assets or the results of operations. At November 30, 2012, the Fund was permitted to carry forward indefinitely $11,431,402 of short-term losses under the Regulated Investment Company Modernization Act of 2010 without limitation. Pioneer Emerging Markets Fund | Annual Report | 11/30/12 39 The tax character of distributions paid during the years ended November 30, 2012 and November 30, 2011 was as follows: ---------------------------------------------------------------------------- 2012 2011 ---------------------------------------------------------------------------- Distributions paid from: Ordinary income $ -- $ -- Long-term capital gain 1,366,437 19,084,107 ---------------------------------------------------------------------------- Total $1,366,437 $ 19,084,107 ============================================================================ The following shows the components of distributable earnings on a federal income tax basis at November 30, 2012: ---------------------------------------------------------------------------- 2012 ---------------------------------------------------------------------------- Distributable earnings: Undistributed ordinary income $ 1,008,839 Capital loss carryforward (11,431,402) Net unrealized gain 19,204,775 ---------------------------------------------------------------------------- Total $ 8,782,212 ============================================================================ The difference between book-basis and tax-basis net unrealized gain 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 $21,951 in underwriting commissions on the sale of Class A shares during the year ended November 30, 2012. 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, 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 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). 40 Pioneer Emerging Markets Fund | Annual Report | 11/30/12 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 R and Class Y shares can reflect different transfer agent and distribution expense rates. G. Risks 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 or 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. H. Securities Lending The Fund may lend securities in its portfolio to certain broker-dealers or other institutional investors. When entering into a securities loan transaction, the Fund typically receives cash collateral from the borrower equal to at least the value of the securities loaned, which is invested in temporary investments. Credit Suisse AG, New York Branch, as the Fund's securities lending agent, manages the Fund's securities lending collateral. The income earned on the investment of collateral is shared with the borrower and the lending agent in payment of any rebate due to the borrower with respect to the securities loan, and in compensation for the lending agent's services to the Fund. The Fund also continues to receive payments in lieu of dividends or interest on the securities loaned. Gain or loss on the value of the loaned securities that may occur during the term of the loan will be for the account of the Fund. The amount of the collateral is required to be adjusted daily to reflect any price fluctuation in the value of the loaned securities. If the required market value of the collateral is less than the value of the loaned securities, the borrower is required to deliver additional collateral for the account of the Fund prior to the close of business on that day. The Fund has the right, under the lending agreement, to terminate the loan and recover the securities from the borrower with prior notice. The Fund is required to return the cash collateral to the borrower and could suffer a loss if the value of the collateral, as invested, has declined. As of May 8, 2012, the Fund ended its involvement in the securities lending program. Pioneer Emerging Markets Fund | Annual Report | 11/30/12 41 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. 2. Management Agreement PIM, a wholly owned indirect subsidiary of UniCredit, manages the Fund's portfolio. Management fees are calculated daily at an annual rate of 1.15% of the Fund's average daily net assets up to $1 billion and 1.10% on assets over $1 billion. For the year ended November 30, 2012, the effective management fee (excluding waivers and/or assumption of expenses) was 1.15% of the Fund's average daily net assets. PIM has contractually agreed to limit ordinary operating expenses to the extent required to reduce Fund expenses to 1.95%, 2.85%, 2.85% and 2.20% of the average daily net assets attributable to Class A, Class B, Class C and Class R shares, respectively. Fees waived and expenses reimbursed during the year ended November 30, 2012 are reflected on the Statement of Operations. Class Y shares do not have an expense limitation. These expense limitations are in effect through April 1, 2014. 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 $30,101 in management fees, administrative costs and certain other reimbursements payable to PIM at November 30, 2012. Effective March 5, 2012, PIM has retained Brown Brothers Harriman & Co. to provide certain sub-administration and accounting services to the Fund. 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. 42 Pioneer Emerging Markets Fund | Annual Report | 11/30/12 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 year ended November 30, 2012, such out-of-pocket expenses by class of shares were as follows: -------------------------------------------------------------------------------- Shareholder Communications: -------------------------------------------------------------------------------- Class A $351,633 Class B 19,818 Class C 54,916 Class R 150,794 Class Y 22,509 -------------------------------------------------------------------------------- Total $591,670 ================================================================================ Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $125,453 in transfer agent fees and out-of-pocket reimbursements payable to PIMSS at November 30, 2012. 4. Distribution and Service Plans 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, 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 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. 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 $5,496 in distribution fees payable to PFD at November 30, 2012. 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. Pioneer Emerging Markets Fund | Annual Report | 11/30/12 43 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. Class B shares that are redeemed within five years of purchase are subject to a CDSC at declining rates beginning at 4.00%, based on the lower of cost or market value of shares being redeemed. Redemptions of Class C shares within one year of purchase are subject to a CDSC of 1.00%, based on the lower of cost or market value of shares being redeemed. Shares purchased as part of an exchange remain subject to any CDSC that applied to the original purchase of those shares. There is no CDSC for Class R or Class Y shares. Proceeds from the CDSCs are paid to PFD. For the year ended November 30, 2012, CDSCs in the amount of $11,416 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 year ended November 30, 2012, the Fund's expenses were not reduced under such arrangements. 6. Forward Foreign Currency Contracts At November 30, 2012, 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 settlement hedge contracts open during the year ended November 30, 2012 was $5,922,673. The average value of portfolio hedge contracts open during the year ended November 30, 2012 was $381,284. At November 30, 2012, the Fund had no outstanding portfolio hedges. At November 30, 2012, the Fund's gross forward currency settlement contracts receivable and payable were $1,461,741 and $1,461,759, respectively, resulting in a net payable of $18. 44 Pioneer Emerging Markets Fund | Annual Report | 11/30/12 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 January 20, 2012 was in the amount of $165 million. Under such facility, interest on borrowings was payable at the higher of the London Interbank Offered Rate (LIBOR) on the borrowing date plus 1.25% on an annualized basis or the Federal Funds Rate on the borrowing date plus 1.25% on an annualized basis. The credit facility in effect as of February 15, 2012 is in the amount of $215 million. Under such facility, depending on the type of loan, interest on borrowings is payable at LIBOR plus 0.90% 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, 2012, the Fund had no borrowings under a credit facility. 8.

These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Fund's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of November 30, 2012, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Pioneer Emerging Markets Fund at November 30, 2012, 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 five years in the period then ended, in conformity with U.S. generally accepted accounting principles. /s/ Ernst & Young LLP Boston, Massachusetts January 28, 2013 Pioneer Emerging Markets Fund | Annual Report | 11/30/12 47 Additional Information (unaudited) For the fiscal year ending November 30, 2012, the Fund has elected to pass through foreign tax credits of $500,132. 48 Pioneer Emerging Markets Fund | Annual Report | 11/30/12 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 March 2012 as the Trustees of the Fund agreed on, among other things, an overall approach and timeline for the process. In July 2012, 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 2012 and September 2012. 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, October, and November, 2012 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 each regularly scheduled meeting. At a meeting held on November 13, 2012, 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. 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, its research process and its process for trade execution. The Trustees considered the resources of PIM and the personnel of PIM who provide investment management services to 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 also considered the substantial attention and high priority given Pioneer Emerging Markets Fund | Annual Report | 11/30/12 49 by PIM's senior management to the Pioneer fund complex. In addition, the Trustees considered PIM's plans to increase resources in its investment management function and other enhancements to PIM's advisory capabilities. 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 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 fifth quintile of its Morningstar category for the one, three and five year periods ended June 30, 2012. (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 considered reasons for the underperformance of the Fund relative to its peer group and the steps recently taken by PIM in an effort to improve the performance of the Fund, including changes to the Fund's portfolio management team. The Trustees agreed that they would continue to closely monitor 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 Independent Trustees for this purpose using data provided by Strategic Insight Mutual Trust Research and Consulting, LLC (Strategic Insight), an independent third party. 50 Pioneer Emerging Markets Fund | Annual Report | 11/30/12 The Trustees considered that the Fund's management fee for the twelve months ended June 30, 2012 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 noted that the Fund's management fee was only four basis points higher than the median management fee paid by other funds in its Morningstar category. The Trustees also noted information that showed that the current management fee would be nine basis points above the median management fee of the Fund's Morningstar category at a hypothetical asset level of $1 billion. The Trustees also considered the breakpoint in the management fee schedule and the reduced fee rate on assets over $1 billion. The Trustees considered that the Fund's expense ratio for the twelve months ended June 30, 2012 was in the fifth quintile relative to its Strategic Insight peer group for the comparable period. The Trustees considered the impact of the Fund's non-management fee expenses on the Fund's expense ratio, noting in particular the Fund's shareholder fees and communications expenses. The Trustees reviewed gross and net management fees charged by PIM to its institutional and other clients, including publicly offered European funds, 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 to its other clients and considered the differences in management fees and profit margins for PIM's Fund and non-Fund services. In evaluating the fees associated with PIM'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 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 Pioneer Emerging Markets Fund | Annual Report | 11/30/12 51 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 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 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 also considered the benefits to the Fund and to PIM and its affiliates from the use of "soft" commission dollars generated by the Fund to pay for research and brokerage services. 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. 52 Pioneer Emerging Markets Fund | Annual Report | 11/30/12 Trustees, Officers and Service Providers Investment Adviser Pioneer Investment Management, Inc.

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.
