But with the memory of a deep recession still lingering, businesses and consumers remained cautious about both investing and spending. While business fundamentals showed signs of improvement, there was still a reluctance to hire, and high unemployment remains a problem. Wary investors, concerned about risk, gravitated towards cash and bonds. We remain generally optimistic about the prospects for economic recovery, although it may occur more slowly than many would like. At Pioneer, we have long advocated the benefits of staying diversified and investing for the long term. This strategy has generally performed well for many investors. Bond markets certainly rewarded investors in the first eleven months of 2010. While the equity markets barely budged, equities at the end of November 2010 were inexpensive relative to bonds, compared with historic levels, and represented potentially good value for long-term investors. Pioneer has not changed the basic approach to investing that we have used for more than 80 years. We remain focused on company fundamentals and risk management. Our investment process is based on careful research into individual companies, quantitative analysis, and active portfolio management. This three-pillared process, which we apply to each of our portfolios, is supported by an integrated team approach and is designed to carefully balance risk and reward. Our experienced professionals devote themselves to the careful research needed to identify investment opportunities in markets around the world. 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. 2 Pioneer Emerging Markets Fund | Annual Report | 11/30/10 We invite you to learn more about Pioneer and our time-tested approach to investing by consulting with your financial advisor or visiting us online at www.pioneerinvestments.com.

Pioneer Emerging Markets Fund | Annual Report | 11/30/10 3 Portfolio Management Discussion | 11/30/10 In the following interview, John Pollen, head of emerging markets equity at Pioneer and portfolio manager of Pioneer Emerging Markets Fund, discusses the investment environment and the Fund's performance during the 12 months ended November 30, 2010. Q Please review the investment environment for emerging market equities during the past year ended November 30, 2010. A Emerging market equities delivered a strong return during the 12 months ended November 30, 2010, outperforming (by a wide margin) the developed markets -- as measured by the Morgan Stanley Capital International (MSCI) World Index(1) -- which returned just 6.52% over the 12-month period, compared with a 15.65% return for the MSCI Emerging Markets Index. Three important factors combined to underpin the strong performance of emerging market equities. First, ultra-low interest rates in the world's largest economies created an abundance of liquidity and fueled investors' risk appetites, thus energizing demand for emerging market stocks. Second, economic growth in the emerging markets remained very strong, supported by healthy government finances, sound fiscal policies, and robust export volumes. At the same time, the developed markets were pressured by concerns about slow growth and soaring levels of government debt -- providing a clear contrast for global investors. Third, the surging price of grains, metals, and various industrial commodities boosted revenues for both governments and corporations in the emerging markets. Q How did the Fund perform in that environment over the 12 months ended November 30, 2010? A Over the 12 months ended November 30, 2010, Pioneer Emerging Markets Fund Class A shares returned 12.85% at net asset value, while the Fund's benchmark, the MSCI Emerging Markets Index (the MSCI Index), returned 15.65%. Over the same 12-month period, the average return of the 392 mutual funds in Lipper's Emerging Markets Funds Category was 16.26%. Q What were the key factors that helped the Fund's performance over the 12 months ended November 30, 2010? A The Fund generated its best performance in the consumer discretionary sector over the 12-month period, where value was added through both an overweight allocation and strong stock selection. The Fund held an average 4 Pioneer Emerging Markets Fund | Annual Report | 11/30/10 weighting of nearly 12% in the sector over the 12 months, a little less than double the benchmark's weighting. In our view, many consumer discretionary stocks offer the best way to capitalize on the rapid growth of the middle class in the emerging markets. The auto sector, in particular, was an area of strength for the Fund. Auto sales in the emerging markets were very strong over the past year ended November 30, 2010, and we expect that autos will continue to represent an area of substantial long-term opportunity due to the rising wealth of consumers in many emerging markets. In India, for example, growing demand for autos prompted Volkswagen and Hyundai to introduce waiting lists for their cars. Those favorable trends form the basis for the Fund's positions in stocks such as Astra International (Indonesia), Bajaj Auto (India), and Kia Motors (Korea), all of which outperformed over the period and added to the Fund's 12-month performance results. Outside of the auto sector, one of the Fund's top performers was the Brazilian retailer Lojas Renner. Energy was another area of notable strength for the Fund over the 12 months ended November 30, 2010, thanks to both an underweight allocation and the outperformance of some individual stock picks. The largest contribution to the Fund's performance came from an underweight in the Brazilian energy giant Petrobras, which sharply lagged the performance of the broader energy sector. The stock was hurt by rising costs and the company's issuance of new shares to help fund the development of its offshore properties. Also contributing to the Fund's performance in energy was an out-of-benchmark position in Pacific Rubiales Energy and an underweight position in the Russian natural gas producer Gazprom. Q What were the leading causes of the Fund's underperformance of its benchmark and Lipper peers during the 12 months ended November 30, 2010? A Unfortunately, the impact of the Fund's outperformance in the consumer discretionary and energy sectors was more than offset by a shortfall in other areas. In terms of stock selection, the Fund's worst area of performance was in the consumer staples sector. Lack of Fund positions in a number of the sector's key winners, together with holdings in a handful of underperforming stocks, caused the Fund to generate a return that was only about half of the gain for the consumer staples stocks in the MSCI Index benchmark. The Fund's most notable laggard was Chaoda Modern Agriculture, which fell heavily after announcing a convertible bond offering to raise capital. Pioneer Emerging Markets Fund | Annual Report | 11/30/10 5 The industrials sector proved to be an additional area of weakness for the Fund over the 12 months ended November 30, 2010, due largely to positions in three stocks that produced negative returns despite the rising market: China Railway Construction; Hyundai Engineering & Construction; and China Communications Construction. Outside of those two sectors (consumer staples and industrials), the most significant underperformer in the Fund's portfolio was Iamgold, a miner of gold and other metals with operations in Africa, Canada, and South America. Q How was the Fund positioned in terms of countries and sectors as of November 30, 2010? A From a country perspective, the Fund's main overweights were in Brazil, Turkey, India, and Indonesia, while its key underweights were in China, Taiwan, Korea, and South Africa. China remains the Fund's largest underweight, but we began to increase portfolio exposure to China late in the 12-month period. The situation in China is crucial for investor sentiment, as the Chinese government's monetary tightening measures spooked investors earlier in 2010, although there have been good signs lately that the authorities' actions have cooled property speculation without taking a meaningful bite out of growth. Chinese economic growth has remained more resilient than expected, and market performance improved late in the 12-month period despite ongoing concerns about inflation. On a sector basis, the Fund's main overweight positions were in consumer discretionary, materials, and health care. The Fund's largest underweights were in energy, information technology, and telecommunications services. Q What is your broader view on the emerging markets? A We believe there are still many powerful reasons why emerging equity markets can move higher, such as stronger liquidity, robust economic growth, healthy government finances, strong foreign currency reserves and continued upgrades to earnings estimates. In particular, emerging markets have much lower debt levels than governments in the developed world, an issue that is currently in the spotlight and is likely to remain so for several years. We believe their healthier fiscal position and much stronger domestic demand should drive superior growth in the emerging markets for a multi-year period. The valuation picture also appears positive, as valuations have been falling for the past year and are by no means expensive on either a relative or 6 Pioneer Emerging Markets Fund | Annual Report | 11/30/10 historical basis. Indeed, many analysts have been upgrading earnings expectations on the strength of better-than-expected earnings and higher commodity prices -- an important factor for valuations since positive earnings surprises can move markets higher without expanding earnings multiples. There is a very good case, we think, for arguing that emerging markets deserve to trade at a premium to developed markets, based on significantly stronger economic growth and generally sound corporate fundamentals. Additionally, many investors are underexposed to the asset class and will need to continue rebalancing portfolios as emerging markets gain a higher share of global stock market capitalization. Recent flows, especially into exchange-traded funds, have been strong, and we expect that the trend will continue, giving further momentum to emerging equity markets. Despite the many positives, we are closely monitoring potential pitfalls, such as volatility in the U.S. dollar, inflation, protectionist policies/capital controls, and the pace of monetary tightening, which could be a negative if rates are raised too early or by too much. There are also exogenous risks, mainly in developed countries, such as the debt problems in Ireland, Greece and other European nations, along with weak employment in the United States. Although investors' risk aversion increased during the final weeks of the annual reporting period ended November 30, 2010, we remain bullish on the outlook for the emerging markets. The prevalence of downside risks, however, means that there are likely to be periods of risk aversion and market weakness. We are therefore seeking to maintain a balance in the Fund's portfolio between quality names exposed to growth -- especially in domestic consumption -- and those companies that appear to be more stable and offer downside protection.

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, 2012 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 | 11/30/10 Performance Update | 11/30/10 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 | 11/30/10 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, 2010, through November 30, 2010. - ---------------------------------------------------------------------------------------------------------------- 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 6/1/10 - ---------------------------------------------------------------------------------------------------------------- Ending Account Value $ 1,215.27 $ 1,209.56 $ 1,209.71 $ 1,214.09 $ 1,218.99 (after expenses) on 11/30/10 - ---------------------------------------------------------------------------------------------------------------- Expenses Paid $ 10.77 $ 15.79 $ 15.29 $ 11.66 $ 8.01 During Period* - ---------------------------------------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.94%, 2.85%, 2.76%, 2.10% and 1.44% for Class A, Class B, Class C, Class R and Class Y shares, respectively, multiplied by the average account value over the period, multiplied by 183/365 (to reflect the one-half year period). 16 Pioneer Emerging Markets Fund | Annual Report | 11/30/10 Hypothetical Example for Comparison Purposes The table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads), that are charged at the time of the transaction. Therefore, the table below is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher.

Organization and Significant Accounting Policies Pioneer 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 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 Pioneer Emerging Markets Fund | Annual Report | 11/30/10 35 principal risks. Please refer to that document when considering the Fund's principal risks. 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: 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. Securities for which market prices and/or quotations are not readily available or are considered to be unreliable are valued using fair value methods pursuant to procedures adopted by the Board of Trustees. The Fund 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. 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. Thus, the valuation of the Fund's securities may differ from exchange prices. At November 30, 2010, there were no securities that were valued using fair value methods (other than securities that were valued using prices supplied by independent pricing services). Inputs used when applying fair value methods to value a security may include credit ratings, the financial 36 Pioneer Emerging Markets Fund | Annual Report | 11/30/10 condition of the company, current market conditions and comparable securities. Short-term fixed income securities with remaining maturities of sixty days or less generally are valued at amortized cost. Money market mutual funds are valued at net asset value. 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). 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 Pioneer Emerging Markets Fund | Annual Report | 11/30/10 37 all of its taxable income and net realized capital gains, if any, to its share-owners. Therefore, no federal income tax provision is required. Tax years for the prior three fiscal years remain subject to examination by 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, 2010, 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, 2010, the Fund had $1,061,815 in reserve related to capital gains. The amounts and characterizations of distributions to shareowners for financial reporting purposes are determined in accordance with federal income tax rules. Therefore, the sources of the Fund's distributions may be shown in the accompanying financial statements as from or in excess of net investment income or as from net realized gain on investment transactions, or as from paid-in capital, depending on the type of book/tax differences that may exist. At November 30, 2010, the Fund has reclassified $282,513 to decrease undistributed net investment income, $1,909,512 to decrease paid-in capital and $2,192,025 to decrease accumulated net realized loss on investments and foreign currency transactions to reflect permanent book/tax differences. The reclassification has no impact on the net asset value of the Fund and is designed to present the Fund's capital accounts on a tax basis. At November 30, 2010, the Fund had a net capital loss carryforward of $51,090,971, which will expire in 2017 if not utilized. The Fund has elected to defer approximately $61,166 of currency losses recognized between November 1, 2010 and November 30, 2010 to its fiscal year ending November 30, 2011. The tax character of distributions paid during the years ended November 30, 2010 and November 30, 2009 was as follows: - -------------------------------------------------------------------------------- 2010 2009 - -------------------------------------------------------------------------------- Distributions paid from: Ordinary income $1,110,508 $3,671,076 - -------------------------------------------------------------------------------- Total $1,110,508 $3,671,076 ================================================================================ 38 Pioneer Emerging Markets Fund | Annual Report | 11/30/10 The following shows the components of distributable earnings on a federal income tax basis at November 30, 2010: - -------------------------------------------------------------------------------- 2010 - -------------------------------------------------------------------------------- Distributable earnings: Capital loss carryforward $(51,090,971) Post-October loss deferred (61,166) Unrealized appreciation 162,048,356 - -------------------------------------------------------------------------------- Total $110,896,219 ================================================================================ The difference between book-basis and tax-basis unrealized appreciation 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 $44,922 in underwriting commissions on the sale of Class A shares during the year ended November 30, 2010. 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, which 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 B, Class C, Class R and Class Y shares can reflect different transfer agent and distribution expense rates. G. Securities Lending The Fund lends securities in its portfolio to certain broker-dealers or other institutional investors. When entering into a securities loan transaction, the Pioneer Emerging Markets Fund | Annual Report | 11/30/10 39 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. H. Repurchase Agreements With respect to repurchase agreements entered into by the Fund, the value of the underlying securities (collateral), including accrued interest, is required to be equal to or in excess of the repurchase price. The collateral for all repurchase agreements is held in safekeeping in the customer-only account of the Fund's custodian or a subcustodian of the Fund. The Fund's investment adviser, Pioneer Investment Management, Inc. (PIM), is responsible for determining that the value of the collateral remains at least equal to the repurchase price. 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% of the Fund's average daily net assets over $1 billion. Prior to January 1, 2010, the Fund paid management fees calculated daily at an annual rate of 1.15% of the Fund's average daily net assets. For the year ended November 30, 2010, the effective management fee 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. Expenses waived during the year ended November 30, 2010 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, 40 Pioneer Emerging Markets Fund | Annual Report | 11/30/10 2012. There can be no assurance that PIM will extend the expense limitation agreement for a class of shares beyond the dates 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 $20,693 in management fees, administrative costs and certain other reimbursements payable to PIM at November 30, 2010. 3. Transfer Agent PIMSS, a wholly-owned indirect subsidiary of UniCredit, provides substantially all transfer agent and shareowner services to the Fund at negotiated rates. In addition, the Fund reimburses PIMSS for out-of-pocket expenses incurred by PIMSS related to shareholder communications activities such as proxy and statement mailings, outgoing phone calls and omnibus relationship contracts. For the year ended November 30, 2010, such out of pocket expenses by class of shares were as follows: - -------------------------------------------------------------------------------- Shareholder Communications: - -------------------------------------------------------------------------------- Class A $519,642 Class B 35,426 Class C 102,928 Class R 181,345 Class Y 75,215 - -------------------------------------------------------------------------------- Total $914,556 ================================================================================ Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $139,067 in transfer agent fees and out-of-pocket reimbursements payable to PIMSS at November 30, 2010. 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. Pioneer Emerging Markets Fund | Annual Report | 11/30/10 41 Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $6,174 in distribution fees payable to PFD at November 30, 2010. 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 18 months of purchase (within 12 months for purchases made on or after April 1, 2009). 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, 2010, CDSCs in the amount of $41,768 were paid to PFD. 5. Expense Offset Arrangements The Fund has entered into certain expense offset arrangements with PIMSS resulting in a reduction in the Fund's total expenses, due to interest earned on cash held by PIMSS. For the year ended November 30, 2010, the Fund's expenses were not reduced under such arrangements. 6. Forward Foreign Currency Contracts At November 30, 2010, 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.

Line of Credit Facility The Fund, along with certain other funds in the Pioneer Family of Funds (the Funds), participates in a $165 million committed, unsecured revolving line of credit facility. Borrowings are used solely for temporary or emergency purposes. The Fund may borrow up to the lesser of the amount available under the facility or the limits set for borrowing by the Fund's prospectus and the 1940 Act. Interest on borrowings is payable at the higher of the London Interbank Offered Rate (LIBOR) on the borrowing date plus 1.25% on an annualized basis or the Federal Funds Rate on the borrowing date plus 1.25% on an annualized basis.

Subsequent Events In preparing these financial statements, PIM has evaluated the impact of all events and transactions for potential recognition or disclosure and has determined that there were no subsequent events requiring recognition or disclosure in the financial statements. Pioneer Emerging Markets Fund | Annual Report | 11/30/10 43 Report of Independent Registered Public Accounting Firm To the Board of Trustees and Shareowners of Pioneer Emerging Markets Fund: - -------------------------------------------------------------------------------- We have audited the accompanying statement of assets and liabilities of Pioneer Emerging Markets Fund (the "Fund"), including the schedule of investments, as of November 30, 2010, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. 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, 2010, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies 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, 2010, 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 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 26, 2011 44 Pioneer Emerging Markets Fund | Annual Report | 11/30/10 Approval of Investment Advisory Agreement (unaudited) 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 2010 as the Trustees of the Fund agreed on, among other things, an overall approach and timeline for the process. In July 2010, 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 September 2010. 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, 2010 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 16, 2010, 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. In addition, the Trustees considered the arrangements put in place to retain key investment and other personnel. The Trustees also considered the substantial Pioneer Emerging Markets Fund | Annual Report | 11/30/10 45 attention and high priority given by PIM's senior management to the Pioneer fund complex. The Trustees considered that PIM supervises and monitors the performance of the Fund's service providers and provides the Fund with personnel (including Fund officers) and other resources that are necessary for the Fund's business management and operations. The Trustees also considered that, as administrator, PIM is responsible for the administration of the Fund's business and other affairs. The Trustees considered the fees paid to PIM for the provision of administration services. Based on these considerations, the Trustees concluded that the nature, extent and quality of services that had been provided by PIM to the Fund were satisfactory and consistent with the terms of the investment advisory agreement. Performance of the Fund The Trustees 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 fourth quintile of its Morningstar category for the one and ten year periods ended June 30, 2010, in the fifth quintile of its Morningstar category for the three year period ended June 30, 2010, and in the third quintile of its Morningstar category for the five year period ended June 30, 2010. (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 discussed the reasons for the Fund's underperformance with PIM in view of the Fund's investment approach and the market conditions present during the relevant periods. The Trustees agreed that they would continue to monitor the performance of the Fund closely. Management Fee and Expenses The Trustees considered information showing the fees and expenses of the Fund in comparison to the management fees of its peer group of funds as classified by Morningstar and 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. The Trustees considered that the Fund's management fee for the twelve months ended June 30, 2010 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 on assets over $1 billion. The Trustees considered that 46 Pioneer Emerging Markets Fund | Annual Report | 11/30/10 the Fund's expense ratio for the twelve months ended June 30, 2010 was in the fifth quintile relative to its Strategic Insight peer group for the comparable period. The Trustees also considered the impact of the Fund's transfer agency and other non-management fee expenses on the Fund's expense ratio. The Trustees considered the contractual expense limitation agreed to by PIM with respect to the Fund. The Trustees also reviewed management fees charged by PIM to its institutional and other clients. 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 concluded that the management fee payable by the Fund to PIM was reasonable in relation to the nature and quality of the services provided by PIM. Profitability The Trustees considered information provided by PIM regarding the profitability of PIM with respect to the advisory services provided by PIM to the Fund, including the methodology used by PIM in allocating certain of its costs to the management of the Fund. The Trustees also considered PIM's profit margin in connection with the overall operation of the Fund. They further reviewed the financial results realized by PIM and its affiliates from non-fund businesses. The Trustees considered PIM's profit margins with respect to the Fund in comparison to the limited industry data available and noted that the profitability of any adviser was affected by numerous factors, including its organizational structure and method for allocating expenses. The Trustees concluded that PIM's profitability with respect to the management of the Fund was not unreasonable. Economies of Scale The Trustees considered PIM's views relating to economies of scale in connection with the Pioneer Funds as fund assets grow and the extent to which any such economies of scale are shared with funds and fund shareholders. The Trustees 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 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 recent difficult periods for financial markets, as the Pioneer Emerging Markets Fund | Annual Report | 11/30/10 47 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. 48 Pioneer Emerging Markets Fund | Annual Report | 11/30/10 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.

Non-Audit Services Beginning with non-audit service contracts entered into on or after May 6, 2003, the effective date of the new SEC pre-approval rules, the Fund's audit committee is required to pre-approve services to affiliates defined by SEC rules to the extent that the services are determined to have a direct impact on the operations or financial reporting of the Fund. For the years ended November 30, 2010 and 2009, there were no services provided to an affiliate that required the Fund's audit committee pre- approval. (f) If greater than 50 percent, disclose the percentage of hours expended on the principal accountant's engagement to audit the registrant's financial statements for the most recent fiscal year that were attributed to work performed by persons other than the principal accountant's full-time, permanent employees.

The aggregate non-audit fees for the Fund and affiliates, as previously defined, totaled approximately $8,290 in 2010 and $8,290 in 2009. The Fund's audit committee of the Board of Trustees has considered whether the provision of non-audit services that were rendered to the Affiliates (as defined) that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining the principal accountant's independence.
