The housing and auto sectors continue to recover, benefiting from record-low interest rates. Banks' willingness to lend to consumers and businesses also continues to rise, broad measures of inflation remain subdued, and, if the weather cooperates in 2013, food prices should come back down. And, while corporate profit growth has slowed, profits remain high and many U.S. companies continue to both pay and increase dividends*. Offsetting some of these positives are the continued contraction of fiscal policy in Washington and a recessionary Europe. The Federal Reserve's aggressive monetary policy has driven Treasury yields to generational lows and supported investments in all financial assets, including equities and high-yield corporate bonds. For example, the Standard & Poor's 500 Index (the S&P 500), a broad measure of the U.S. stock market, returned 15.99% for the full calendar year ended December 31, 2012, and the Bank of America Merrill Lynch High Yield Master II Index (the High Yield Index), which measures the performance of high-yield corporate bonds, returned 15.59% for the same 12-month period. On the other hand, the Barclays Aggregate Bond Index (the Aggregate Index), which tracks the performance of a higher-quality bond universe, gained 4.22% for the 12 months ended December 31, 2012; the safer-still Barclays Government Credit Index (the Government/Credit Index) returned 4.82%; and 3-month Treasury bills, generally regarded as essentially "risk free" by the markets, returned just 0.09% in 2012. "Risky" assets outperformed again in the first quarter of 2013, as the S&P 500 returned 10.60% and the High Yield Index returned 2.89%. In contrast, the Aggregate Index returned -0.12% in the first quarter, the Government Credit Index returned -0.16%, and Treasury bills returned 0.02%. Despite generally improving economic conditions and a rising stock market, global economies and investors still face daunting challenges as 2013 moves forward, although we remain cautiously optimistic. U.S. fiscal policy remains unsettled, and we feel the U.S. government could be at risk of credit rating downgrades from one or more of the major ratings agencies if the uncertainties persist. The Federal Reserve continues to provide extraordinary support to the U.S. economy and the bond market, but will not do so indefinitely. Europe has made progress, but has not yet resolved its sovereign-debt/banking problem, nor has the region been able to exit recession. Japan recently has unveiled 2 Pioneer International Value Fund | Semiannual Report | 5/31/13 aggressive and unconventional monetary and fiscal policies, but the country continues to face issues such as high levels of debt as well as an aging population. China and other emerging economies, while generally in better shape than most "developed" markets, also face a range of challenges. While most of the risks outlined here are widely recognized and may already be "priced in" to the market, we believe investors should continue to expect market volatility. At Pioneer, we have long advocated the benefits of staying diversified and investing for the long term. And while diversification does not assure a profit or protect against loss in a declining market, we believe there are still opportunities for prudent investors to earn attractive returns. Our advice, as always, is to work closely with a trusted financial advisor to discuss your goals and work together to develop an investment strategy that meets your individual needs, keeping in mind that there is no single best strategy that works for every investor. Pioneer's investment teams have, since 1928, sought out attractive opportunities in global equity and bond markets, using in-depth research to identify undervalued individual securities, and using thoughtful risk management to construct portfolios which balance potential risks and reward in an ever-changing world. We encourage you to learn more about Pioneer and our time-tested approach to investing by consulting with your financial advisor or visiting us online at us.pioneerinvestments.com. We greatly appreciate your trust in us, and we thank you for investing with Pioneer. Sincerely, /s/ Daniel K. Kingsbury Daniel K. Kingsbury President and CEO Pioneer Investment Management USA, Inc.

Pioneer International Value Fund | Semiannual Report | 5/31/13 3 Portfolio Management Discussion | 5/31/13 In the follow interview, Madelynn Matlock discusses the market environment for international equities and the factors that influenced the performance of Pioneer International Value Fund during the six months ended May 31, 2013. Ms. Matlock, a senior vice president and a portfolio manager at Pioneer, was named a portfolio manager on the Fund in December 2012. Ms. Matlock, Marco Pirondini, Head of Equities, U.S., and a portfolio manager at Pioneer, and Andrea Salvatore, Head of Global Emerging Markets & Latin American Equities and a portfolio manager based in Pioneer's London office, are responsible for the day-to-day management of the Fund. Q International stocks delivered solid gains during the six months ended May 31, 2013. What factors contributed to the strong performance of the asset class during the period? A International equity markets faced some uncertainty in the early months of the six-month period, but shrugged off those concerns and ultimately posted double-digit gains. During the first quarter of 2013, the failure of Italy's elections to produce a majority government, combined with the bailout of the banking system in Cyprus, created some trepidation among international investors. In addition, China, which has been an engine of growth for the world economy, was encountering its own economic slowdown. Questions about the direction in which China's new leader, Xi Jinping, would take the country especially with regard to banking reform and the creation of more open capital markets also unnerved investors. While such concerns were abundant throughout the period, the massive amount of liquidity injected into capital markets by very accommodative global central banks helped to offset them, as did the election of new leadership in Japan, a leadership that seemed committed to reforms aimed at helping the country to transition out of its ongoing economic malaise. Ultimately, investors embraced "risk" assets, and stock markets in the Pacific Rim, the emerging markets, and Europe rallied. Q How did Pioneer International Value Fund perform in that environment during the six months ended May 31, 2013? A Pioneer International Value Fund's Class A shares returned 12.37% at net asset value during the six months ended May 31, 2013, while the Fund's benchmark, the Morgan Stanley Capital International (MSCI) Europe, 4 Pioneer International Value Fund | Semiannual Report | 5/31/13 Australasia, Far East (EAFE) ND Index1 (the MSCI EAFE Index), returned 11.39%. During the same period, the average return of the 331 mutual funds in Lipper's International Multi-Cap Core Funds category was 9.93%. Q Which of your investment strategies contributed to the Fund's strong showing relative to its benchmark and Lipper peer group during the six months ended May 31, 2013? A Early in 2013, we took steps to fine-tune the portfolio in light of the changing investment environment. Probably the most significant adjustment was to bring the Fund's exposure to Japanese stocks more in line with the MSCI EAFE Index. With the election of a new prime minister in November 2012, a man committed to economic reform to jumpstart the Japanese economy, our outlook for Japanese growth improved. We were not disappointed with the results, as Japanese stocks turned in strong performance during the period. New economic reforms aimed at spurring consumers and businesses to spend and helping to move the country out of its multi-year disinflationary cycle were warmly received by investors. The prime minister appointed a new governor of the Bank of Japan, who immediately took steps to ease monetary policy, which ultimately produced a major devaluation of the yen. A weaker yen relative to other currencies helps to make Japanese products more affordable in foreign markets, thus increasing business for Japanese exporters. Q What other strategic decisions favorably influenced the Fund's performance during the six months ended May 31, 2013? A At the beginning of the period, the Fund's exposure to the European Union (EU) was well below that of the MSCI EAFE Index. Initially, the positioning in the EU was beneficial for Fund performance as ongoing sovereign-debt issues weighed on the markets. However, while the region still faces challenges, we feel increasingly reassured about the survival of the EU as a political and economic union, given efforts by the European Central Bank (ECB) to address the hurdles posed by its struggling member nations in recent years. With our belief that the EU could be turning a corner on its (1) The MSCI information may only be used for your internal use, may not be reproduced or redisseminated in any form and may not be used as a basis for or a component of any financial instruments or products or indices.

Pioneer International Value Fund | Semiannual Report | 5/31/13 5 debt-related issues and that European stocks were offering attractive valuations, we increased the Fund's exposure to the region during the period, bringing the portfolio's weighting more in line with that of the MSCI EAFE Index. The Fund also benefited from our decision to trim its investments in the emerging markets later in the six-month period. For some time, the U.S. Federal Reserve's (the Fed's) accommodative monetary policies have been driving investors into stocks and other "risk assets" around the world. Investments in emerging economies, which are perceived to carry more risk than those in developed economies, rallied on the back of this stronger demand. However, with the Fed beginning to hint at winding down its monetary stimulus later this year if unemployment continues to decline at the pace that the central bank expects, we thought it would be prudent to reduce the Fund's exposure to the emerging markets in anticipation of softer demand. In addition, it is our belief that many of the holdings in the emerging markets were becoming overvalued in relation to their future earnings potential. Finally, we began the process of reducing the total number of holdings in the Fund's portfolio during the six-month period. In today's complex investment environment, we think it will be more effective to allocate the Fund's assets among a more limited number of holdings in which we have strong convictions, rather than owning a large number smaller positions. We are likely to continue this process in the coming months as investment opportunities present themselves. Q Which individual Fund holdings had the greatest positive effect on performance during the six months ended May 31, 2013? A A position in Ryanair, the Irish airline company, was the top contributor to the Fund's performance during the six-month period. The company benefited from improvement in the economic outlook for Ireland and the euro zone in general. The Fund's position in Sekisui Chemical also contributed to performance during the period. With its focus on energy-efficient, affordable housing, the company benefited from post-2011 earthquake/tsunami construction activity in Japan. The stock also offers an attractive dividend* yield and carries a good valuation. Finally, the portfolio's investment in Philippine holding company Alliance Global aided the Fund's performance during the period. Alliance, a large conglomerate with interests in the food, beverage, and real estate industries, * Dividends are not guaranteed. 6 Pioneer International Value Fund | Semiannual Report | 5/31/13 posted healthy gains during the period due to the attractiveness of the company's previously low stock price as well as robust growth in the Philippine economy. Q Which individual holdings detracted the most from the Fund's performance during the six months ended May 31, 2013? A A portfolio holding in Japanese convenience store retailer FamilyMart detracted from performance during the period. FamilyMart is pursuing an aggressive store opening strategy worldwide, but daily sales at the company's existing stores were down for a couple of quarters. Since the company didn't perform as investors anticipated, the stock subsequently sold off. The Fund's holding in Saipem, an Italian oil services company, also turned in disappointing results this past spring. The company's announcement of new guidance reflected lower expectations for 2013 earnings, given escalating commercial difficulties in Algeria and operational and technical issues in both Canada and Mexico. Lastly, a position in Telecom Italia hurt the Fund's performance during the period. Telecom Italia saw domestic demand for its products and services slow in response to Italy's recession, and also experienced problems abroad, given the slowdown in Latin American economies. In addition, telecommunications is a capital-intensive business, and operators often carry a fair amount of debt on their balance sheets as result. Thus, the company's stock price experienced further selling pressure from risk-averse investors shunning debt-laden companies. Q What is your outlook for international stocks for the balance of 2013? A With so many factors at play in the financial markets that can influence both the level of volatility and the direction of markets, we are still constructive in our outlook. One of the primary questions that investors are grappling with is whether or not monetary accommodation by global central banks will be removed in a timely manner, and how that will affect a number of "risky" asset classes, including international stocks. In the near term, however, we believe that the major central banks such as the Fed, the ECB, the Bank of England, and the Bank of Japan will continue to inject liquidity, thus helping to support asset prices and providing a floor for any slowing of global economic growth. Corporate balance sheets also remain in great shape and earnings outlooks remain generally healthy. Pioneer International Value Fund | Semiannual Report | 5/31/13 7 While we do take the macroeconomic picture into consideration when evaluating international stocks, we believe that successful investing is rooted in a bottom-up stock selection process. Thus, we think successful investing is as much about paying the right price as it is about being in the right place. Our recent efforts to increase the Fund's exposure to Japan reflect that line of thinking. Given our belief that Europe is on the cusp of turning a corner later this year, we may begin to see greater opportunities there as well. Please refer to the Schedule of Investments on pages 18-25 for a full listing of Fund securities. 8 Pioneer International Value Fund | Semiannual Report | 5/31/13 Investing in foreign and/or emerging markets securities involves risks relating to interest rates, currency exchange rates, economic, and political conditions. The Fund may invest a substantial amount of its assets in issuers located within a specific region, and is, therefore, more susceptible to adverse developments affecting those regions. When interest rates rise, the prices of fixed-income securities in the Fund will generally fall. Conversely, when interest rates fall, the prices of fixed-income securities in the Fund will generally rise. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries or sectors. These risks may increase share price volatility. Past performance is no guarantee of future results, and there is no guarantee that market forecasts discussed will be realized.

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. Class Y shares were first publicly offered on April 16, 2009. Performance shown for periods prior to the inception of Class Y shares reflects the NAV performance of the Fund's Class A shares. The performance does not reflect differences in expenses, including the Rule 12b-1 fees applicable to Class A shares. Since fees for Class A shares are generally higher than those of Class Y shares, the performance for Class Y shares prior to their inception would have been higher than the performance shown. Class Y shares are not subject to sales charges and are available for limited groups of eligible investors, including institutional investors. All results are historical and assume the reinvestment of dividends and capital gains. Other share classes are available for which performance and expenses will differ. Performance results reflect any applicable expense waivers in effect during the periods shown. Without such waivers Fund performance would be lower. Waivers may not be in effect for all funds. Certain fee waivers are contractual through a specified period. Otherwise, fee waivers can be rescinded at any time. See the prospectus and financial statements for more information. The performance table and graph do not reflect the deduction of fees and taxes that a shareowner would pay on Fund distributions or the redemption of Fund shares. Pioneer International Value Fund | Semiannual Report | 5/31/13 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 International Value Fund Based on actual returns from December 1, 2012 through May 31, 2013. -------------------------------------------------------------------------------- Share Class A B C Y -------------------------------------------------------------------------------- Beginning Account $1,000.00 $1,000.00 $1,000.00 $1,000.00 Value on 12/1/12 -------------------------------------------------------------------------------- Ending Account $1,123.70 $1,118.30 $1,118.60 $1,126.00 Value (after expenses) on 5/31/13 -------------------------------------------------------------------------------- Expenses Paid $7.68 $12.41 $12.41 $5.46 During Period* -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized net expense ratio of 1.45%, 2.35%, 2.35% and 1.03% for Class A, Class B, Class C and Class Y shares, respectively, multiplied by the average account value over the period, multiplied by 182/365(to reflect the one-half year period). 16 Pioneer International Value Fund | Semiannual Report | 5/31/13 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), or redemption fees 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 International Value Fund Based on a hypothetical 5% return per year before expenses, reflecting the period from December 1, 2012 through May 31, 2013. -------------------------------------------------------------------------------- Share Class A B C Y -------------------------------------------------------------------------------- Beginning Account $1,000.00 $1,000.00 $1,000.00 $1,000.00 Value on 12/1/12 -------------------------------------------------------------------------------- Ending Account $1,017.70 $1,013.21 $1,013.21 $1,019.80 Value (after expenses) on 5/31/13 -------------------------------------------------------------------------------- Expenses Paid $7.29 $11.80 $11.80 $5.19 During Period* -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized net expense ratio of 1.45%, 2.35%, 2.35% and 1.03% for Class A, Class B, Class C and Class Y shares, respectively, multiplied by the average account value over the period, multiplied by 182/365(to reflect the one-half year period).

Pioneer International Value Fund | Semiannual Report | 5/31/13 33 Notes to Financial Statements | 5/31/13 (unaudited) 1. Organization and Significant Accounting Policies Pioneer International Value Fund (the Fund) is the sole portfolio comprising Pioneer Series Trust VIII, a Delaware statutory trust. The Fund is registered under the Investment Company Act of 1940 as a diversified, open-end management investment company. The investment objective of the Fund is long-term growth of capital. The Fund offers four classes of shares designated as Class A, Class B, Class C and Class Y shares. Class R shares were first publicly offered on April 1, 2003 and ceased operations on February 1, 2007. Class Y shares were first publicly offered on April 16, 2009. 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 gain or loss on investments during the reporting period. Actual results could differ from those estimates. 34 Pioneer International Value Fund | Semiannual Report | 5/31/13 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. Short-term fixed income securities with remaining maturities of sixty days or less generally are valued at amortized cost. Shares of money market mutual funds are valued at such funds' 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 International Value Fund | Semiannual Report | 5/31/13 35 At May 31, 2013, there were no securities valued using fair value methods (other than to securities 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 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). 36 Pioneer International Value Fund | Semiannual Report | 5/31/13 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 share-owners. Therefore, no provision for federal income taxes is required. As of May 31, 2013, 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 remain subject to examination by federal and state tax authorities. In addition to the requirements of the Internal Revenue Code, the Fund may also be required to pay local taxes on the recognition of capital gains and/or the repatriation of foreign currencies in certain countries. During the six months ended May 31, 2013, the Fund paid no such taxes. The amount and character of income and capital gain distributions to shareowners are determined in accordance with federal income tax rules, which may differ from U.S. generally accepted accounting principles. Distributions in excess of net investment income or net realized gains are temporary overdistributions for financial statement purposes resulting from differences in the recognition or classification of income or distributions for financial statement and tax purposes. Capital accounts within the financial statements are adjusted for permanent book/tax differences to reflect tax character, but are not adjusted for temporary differences. The tax character of current year distributions payable will be determined at the end fo the current taxable year. The tax character of distributions paid during the year ended November 30, 2012 was as follows: --------------------------------------------------------------------------- 2012 --------------------------------------------------------------------------- Distribution paid from: Ordinary income $4,932,853 --------------------------------------------------------------------------- Total $4,932,853 =========================================================================== The following shows the components of distributable earnings on a federal income tax basis at November 30, 2012: --------------------------------------------------------------------------- 2012 --------------------------------------------------------------------------- Distributable earnings: Undistributed ordinary income $6,157,327 Capital loss carryforward (176,784,516) Unrealized appreciation 15,415,756 --------------------------------------------------------------------------- Total $(155,211,433) =========================================================================== Pioneer International Value Fund | Semiannual Report | 5/31/13 37 The difference between book-basis and tax-basis net unrealized loss is attributable to the tax deferral of losses on wash sales and the mark-to-market of foreign currency contracts and passive foreign investment companies. 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 $7,699 in underwriting commissions on the sale of Class A shares during the six months ended May 31, 2013. F. Class Allocations Income, common expenses and realized and unrealized gains and losses are calculated at the Fund level and allocated daily to each class of shares based on its respective percentage of adjusted net assets at the beginning of the day. Distribution fees are calculated based on the average daily net asset value attributable to Class A, Class B and Class C shares of the Fund, respectively (see Note 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). 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 and Class Y shares can reflect different transfer agent and distribution expense rates. G. Risks Investing in foreign and/or emerging markets securities involves risks relating to interest rates, currency exchange rates and economic and political conditions. The Fund may invest a substantial amount of its assets in issuers located in a limited number of countries and therefore is susceptible to adverse economic, political or regulatory developments affecting those countries. 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. 38 Pioneer International Value Fund | Semiannual Report | 5/31/13 H. Repurchase Agreements With respect to repurchase agreements entered into by the Fund, the value of the underlying securities (collateral), including accrued interest, is required to be equal to or in excess of the repurchase price. The collateral for all repurchase agreements is held in safekeeping in the customer-only account of the Fund's custodian or a subcustodian of the Fund. PIM is responsible for determining that the value of the collateral remains at least equal to the repurchase price. I. Futures Contracts The Fund may enter into futures transactions to hedge against changes in interest rates, securities prices and currency exchange rates or to seek to increase total return. Futures contracts are types of derivatives. All futures contracts entered into by the Fund are traded on a futures exchange. Upon entering into a futures contract, the Fund is required to deposit with a broker an amount of cash or securities equal to the minimum "initial margin" requirements of the associated futures exchange. Subsequent payments for futures contracts ("variation margin") are paid or received by the Fund, depending on the daily fluctuation in the value of the contracts, and are recorded by the Fund as unrealized gains or losses. When the contract is closed, the Fund realizes a gain or loss equal to the difference between the opening and closing value of the contract as well as any fluctuation in foreign currency exchange rates where applicable. Futures contracts are subject to market risk, interest rate risk and currency exchange rate risk. Changes in value of the contracts may not directly correlate to the changes in value of the underlying securities. These risks may decrease the effectiveness of the Fund's hedging strategies and potentially result in a loss. With futures, there is minimal counterparty credit risk to the Fund since futures are exchange-traded and the exchange's clearinghouse, as counterparty to all exchange-traded futures, guarantees the futures against default. During the six months ended May 31, 2013 the Fund had no outstanding futures contracts. There were no open futures contracts on May 31, 2013. 2. Management Agreement PIM, a wholly owned indirect subsidiary of UniCredit, manages the Fund's portfolio. Management fees are calculated daily at the annual rate of 0.85% of the Fund's average daily net assets up to $500 million and 0.75% of the excess over $500 million. For the six months ended May 31, 2013, the effective management fee (excluding waivers and/or assumptions of expenses) was equivalent to 0.85% of the Fund's average daily net assets. Pioneer International Value Fund | Semiannual Report | 5/31/13 39 PIM has contractually agreed to limit ordinary operating expenses to the extent required to reduce Fund expenses to 1.45%, 2.35% and 2.35%, of the average daily net assets attributable to Class A, Class B and Class C shares, respectively. Fees waived and expenses reimbursed during the six months ended May 31, 2013 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 $19,954 in management fees, administrative costs and certain other reimbursements payable to PIM at May 31, 2013. 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. In addition, the Fund reimburses PIMSS for out-of-pocket expenses incurred by PIMSS related to shareholder communications activities such as proxy and statement mailings, outgoing phone calls and omnibus relationship contracts. For the six months ended May 31, 2013, such out-of-pocket expenses by class of shares were as follows: -------------------------------------------------------------------------------- Shareholder Communications: -------------------------------------------------------------------------------- Class A $ 41,992 Class B 4,253 Class C 3,769 Class Y 71,447 -------------------------------------------------------------------------------- Total $121,461 ================================================================================ Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $72,195 in transfer agent fees and out-of-pocket reimbursements payable to PIMSS at May 31, 2013. 40 Pioneer International Value Fund | Semiannual Report | 5/31/13 4. Distribution Plan The Fund has adopted a Distribution Plan pursuant to Rule 12b-1 of the Investment Company Act of 1940 with respect to its Class A, Class B and Class C shares. Pursuant to the Plan, the Fund pays PFD 0.25% of the average daily net assets attributable to Class A shares as compensation for personal services and/or account maintenance services or distribution services with regard to Class A shares. Pursuant to the Plan, the Fund also pays PFD 1.00% of the average daily net assets attributable to Class B and Class C shares. The fee for Class B and Class C shares consists of a 0.25% service fee and a 0.75% distribution fee paid as compensation for personal services and/or account maintenance services or distribution services with regard to Class B and Class C shares. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $1,930 in distribution fees payable to PFD at May 31, 2013. In addition, redemptions of each class of shares (except Class Y shares) may be subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may be imposed on redemptions of certain net asset value purchases of Class A shares within 12 months of purchase. Class B shares 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 Y shares. Proceeds from the CDSCs are paid to PFD. For the six months ended May 31, 2013, CDSCs in the amount of $2,058 were paid to PFD. 5. Expense Offset Arrangements The Fund has entered into certain expense offset arrangements with PIMSS which may result in a reduction in the Fund's total expenses, due to interest earned on cash held by PIMSS. For the six months ended May 31, 2013, the Fund's expenses were not reduced under such arrangements. 6. Forward Foreign Currency Contracts At May 31, 2013, 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 portfolio hedges open during the six months ended May 31, 2013 was $6,917,164. The average value of settlement hedges open during the six months ended May 31, 2013 was $7,660,739. At May 31, 2013, the Fund's gross forward currency settlement Pioneer International Value Fund | Semiannual Report | 5/31/13 41 contracts receivable and payable were $10,579,150 and $10,583,291, respectively, resulting in a net payable of $4,141. There were no open portfolio hedges at May 31, 2013. 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 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 the London Interbank Offered Rate (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 Euro dollar 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 six months ended May 31, 2013, the Fund had no outstanding borrowings. 8.

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.
