The markets reacted quite negatively to the credit downgrade, and there is concern about the strength of the global economy going forward. Pioneer is cautiously optimistic that the U.S. economy will see moderate economic growth over the balance of 2011, though at a slower pace than we had expected earlier this year. While housing and employment remain weak, the private sector shows signs of slow but steady improvement, led by higher capital investment, solid exports, improved consumption, and gradually rising demand for consumer auto loans and commercial loans. At the same time, the risks to growth remain substantial, including high unemployment, continued delays in the housing sector's recovery, and the fiscal drag of U.S. federal and state budget cuts. The difficult recovery process has been accompanied by wide market swings. While this is a challenging environment, our investment professionals continue to focus on finding good opportunities to invest in both equity and bond markets using the same disciplined approach Pioneer has used since 1928. Our approach is to identify undervalued individual securities with the greatest potential for success, carefully weighing risk against reward. Our teams of investment professionals continually monitor and analyze the relative valuations of different sectors and securities globally to help build portfolios that we believe can help you achieve your investment goals. At Pioneer, we have long advocated the benefits of staying diversified and investing for the long term. The strategy has generally performed well for many investors. 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. 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 2 Pioneer Cullen Value Fund | Annual Report | 6/30/11 us.pioneerinvestments.com.

Pioneer Cullen Value Fund | Annual Report | 6/30/11 3 Portfolio Management Discussion | 6/30/11 Stocks rallied throughout the 12 months ended June 30, 2011, sustaining the market rally that began in 2009, when investors began anticipating a recovery from recession. While more speculative stocks continued to lead the market surge, signs appeared late in the period that more conservative, dividend-paying value stocks were gaining in relative performance. In the following discussion, James P. Cullen, president of Cullen Capital Management LLC, the Fund's subadviser, reviews the factors that affected the performance of Pioneer Cullen Value Fund during the 12 months ended June 30, 2011. Mr. Cullen oversees the team responsible for the daily management of the Fund. Q How did the Fund perform over the 12 months ended June 30, 2011? A Pioneer Cullen Value Fund Class A shares returned 25.50% at net asset value during the 12 months ended June 30, 2011, while the Fund's benchmark, the Standard & Poor's 500 Index (the S&P 500), returned 30.68%. Over the same period, the 500 mutual funds in Lipper's Large Cap Value category produced an average return of 28.33%. Q How would you describe the market environment over the 12 months ended June 30, 2011, and how was the Fund positioned during the 12-month period? A The recovery phase of the stock market cycle, rallying from the severe downturn of 2008 and early 2009, continued over the 12 months ended June 30, 2011. In the early phases of the period, the dominant trend continued to be that more speculative stocks produced the best returns in a very volatile market surge that was heavily influenced by high-frequency traders and investors who were shorting -- or betting against -- individual stocks. Fundamental investing strategies and value disciplines tended to underperform in that environment. We saw signs, however, that the trend favoring high-risk strategies might be waning during the first half of 2011, and that more conservative strategies, especially those that favored higher-dividend and value stocks, were beginning to demonstrate improved performance relative to the overall market. That is more typical of the longer-term historical record, as value stocks have tended to fare better in the latter periods of recoveries as well as throughout the recovery cycle. Over the 12 months ended June 30, 2011, even though the economic recovery appeared to be proceeding slowly, corporate earnings rose briskly, with many corporations able to strengthen their balance sheets and build up their cash reserves. While economic fundamentals appeared encouraging, 4 Pioneer Cullen Value Fund | Annual Report | 6/30/11 often the day-to-day headline news inspired less confidence. Unemployment, for example, remained at high levels, which also is typical when economies first begin recovering from severe recessions, as many companies are often slow to build up their staffing levels until they have been persuaded that the recovery has taken hold and their earnings have increased significantly. Throughout the 12-month period, we held to our long-term discipline for the Fund, emphasizing fundamental analysis of individual stocks and focusing on higher-quality companies, including many with good dividends that were selling at relatively low valuations. The Fund maintained overweighted positions in the industrials, health care and consumer staples sectors during the period, with healthy positions in companies that are involved in international markets, especially the fast-growing emerging economies, and to stocks with higher dividend yields. Q What types of investments most influenced the Fund's performance over the 12 months ended June 30, 2011? A While the Fund's return lagged that of the benchmark S&P 500 over the 12-month period, virtually all of the Fund's holdings produced positive results. The high-dividend stocks in which the Fund was invested performed particularly well. The Fund's investments in industrials stocks, especially those highly exposed to growing global markets, fared very well during the period, as did the higher-dividend stocks held in the portfolio. Even though we underweighted the Fund both to the financials and information technology sectors, poor stock selection in those areas was the primary factor behind the Fund's underperformance of the S&P 500. In the case of financials, we focused on big U.S. money center banks such as Citigroup and JPMorgan Chase. Alas, even though the two institutions were less exposed to European sovereign debt problems than many other global financial institutions, their performance was hurt by concerns about what exposure they did have. The Fund held a major position in Citigroup because it was the most heavily exposed to international markets, while we invested the Fund in JPMorgan Chase because we believed it was the best-managed company in the money center banking group. Information technology stocks were out of favor during the 12-month period ended June 30, 2011, especially the larger companies in the group that the Fund typically owns. For example, the share price of Microsoft, which was a Fund holding, declined during the period. Overweighted Fund positions in industrials, health care and consumer staples all helped results. Many of the Fund's industrials holdings exposed to the global economic recovery produced very good returns during the period, including Boeing, ITT, United Technologies, and 3M, as well as two European corporations that are major players in infrastructure development Pioneer Cullen Value Fund | Annual Report | 6/30/11 5 in emerging markets -- ABB of Germany and Alstom of France. Fluor, another global infrastructure-related stock, performed well for the Fund before we took profits and sold it. The Fund had a heavy weighting in pharmaceuticals during the 12-month period, and the positioning helped results, with major companies such as Abbott Laboratories, Bristol-Myers Squibb, Johnson & Johnson and German company A.G. Bayer all faring well. Growing global demand for basic consumer goods, especially in the emerging economies, helped propel returns from the Fund's consumer staples investments in companies such as Unilever, Kimberly-Clark, Nestle and Kraft Foods. In the consumer discretionary group, the Fund's position in Walt Disney Company did very well. Our preference for owning globally oriented energy companies in the Fund's portfolio helped drive results, particularly during the first half of 2011 when many energy stocks doubled in value as global energy prices rose. Stocks held by the Fund that performed well during the 12-month period included integrated oil company Conoco Phillips; Gazprom, the Russian natural gas producer; PetroChina; and Petrobras, the Brazilian oil giant that we added to the Fund's portfolio in March of 2011. While positioning and stock selection in information technology detracted from the Fund's overall benchmark-relative return comparisons over the 12 months ended June 30, 2011, Hewlett Packard, one of the Fund's holdings in the sector, did perform well. The company's new chief executive outlined a plan to raise earnings over the next two years and the market responded positively to the news. Nevertheless, as noted earlier, the Fund's information technology holdings, including the aforementioned Microsoft, generally disappointed over the 12-month period. Q What is your investment outlook? A Although many of the headline news stories about the economy may not have been too encouraging of late, as investors we remain focused on corporate earnings stories, which have been much more positive. We invest the Fund in companies that we think should produce healthy streams of growing earnings in the future, relative to their stock prices. We maintain a five-year outlook, and focus on economic fundamentals, not the emotional issues that drive market movements each day. Paying close attention to the historical trends that have emerged as the economy has pulled out of past recessions, and examining the emerging economic fundamentals, we think that we are well into a corporate earnings recovery cycle that should bring about a strengthened, growing economy in the years ahead. That would reward investors who focus on underlying economic fundamentals rather than the daily headline news. As the cycles play out, we should remember that disciplined value strategies such as the one applied to Pioneer Cullen 6 Pioneer Cullen Value Fund | Annual Report | 6/30/11 Value Fund have tended to outperform over longer periods of the recovery cycle. We believe the outlook for the market is good, especially for the value- oriented investment discipline. Please refer to the Schedule of Investments on pages 18-24 for a full listing of Fund securities Mid-sized companies may offer the potential for higher returns, but are also subject to greater short-term price fluctuations than larger, more established companies. The Fund invests in a limited number of securities and, as a result, the Fund's performance may be more volatile than the performance of other funds holding more securities. Investing in foreign and/or emerging markets securities involves risks relating to interest rates, currency exchange rates, economic, and political conditions. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. These risks may increase share price volatility. Past performance is no guarantee of future results, and there is no guarantee that market forecasts discussed will be realized.

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. Pioneer Cullen Value Fund acquired the assets and liabilities of the predecessor Cullen Value Fund on February 25, 2005. The performance shown for Class Y shares of the Fund from July 1, 2000, to February 25, 2005, is the performance of the predecessor Cullen Value Fund's single class, which has not been restated to reflect any differences in expenses. The predecessor Cullen Value Fund had higher expenses than those of the Fund's Class Y shares. Since the fees for the predecessor fund's single class were higher than those of Class Y shares of the Fund, the performance of 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 net expense ratio reflects the contractual expense limitations currently in effect through June 1, 2012, for Class Y 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 Cullen Value Fund | Annual Report | 6/30/11 Performance Update | 6/30/11 Class Z Shares Investment Returns -------------------------------------------------------------------------------- The mountain chart on the right shows the change in value of a $10,000 investment made in Pioneer Cullen Value Fund, compared to that of the S&P 500 Index.

Pioneer Cullen Value Fund acquired the assets and liabilities of the predecessor Cullen Value Fund on February 25, 2005. The performance shown for Class Z shares of the Fund from July 1, 2000, to February 25, 2005, is the performance of the predecessor Cullen Value Fund's single class, which has not been restated to reflect any differences in expenses. The predecessor Cullen Value Fund had higher expenses than those of the Fund's Class Z shares. Performance shown for Class Z shares for the period from February 25, 2005, to the inception of Class Z shares on November 1, 2008, reflects the NAV performance of the Pioneer Cullen Value 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 Z shares, the performance for Class Z shares prior to their inception would have been higher than that shown. Class Z 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.

Pioneer Cullen Value Fund | Annual Report | 6/30/11 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 Cullen Value Fund Based on actual returns from January 1, 2011, through June 30, 2011. ----------------------------------------------------------------------------------------------------------------------- Share Class A B C R Y Z ----------------------------------------------------------------------------------------------------------------------- Beginning Account $ 1,000.00 $ 1,000.00 $ 1,000.00 $ 1,000.00 $ 1,000.00 $ 1,000.00 Value on 1/01/11 ----------------------------------------------------------------------------------------------------------------------- Ending Account Value $ 1,255.00 $ 1,243.70 $ 1,245.40 $ 1,251.50 $ 1,259.20 $ 1,259.80 (after expenses) on 6/30/11 ----------------------------------------------------------------------------------------------------------------------- Expenses Paid During Period* $ 5.73 $ 10.42 $ 9.46 $ 7.09 $ 3.96 $ 3.86 ----------------------------------------------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.13%, 2.06%, 1.87%, 1.40%, 0.78%, and 0.76% for Class A, Class B, Class C, Class R, Class Y, and Class Z shares respectively, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period). 16 Pioneer Cullen Value Fund | Annual Report | 6/30/11 Hypothetical Example for Comparison Purposes The table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads) that are charged at the time of the transaction. Therefore, the table below is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher. Expenses Paid on a $1,000 Investment in Pioneer Cullen Value Fund Based on a hypothetical 5% per year return before expenses, reflecting the period from January 1, 2011, through June 30, 2011. --------------------------------------------------------------------------------------------------------------------------- Share Class A B C R Y Z --------------------------------------------------------------------------------------------------------------------------- Beginning Account $ 1,000.00 $ 1,000.00 $ 1,000.00 $ 1,000.00 $ 1,000.00 $ 1,000.00 Value on 1/01/11 --------------------------------------------------------------------------------------------------------------------------- Ending Account Value $ 1,019.19 $ 1,014.58 $ 1,015.52 $ 1,017.85 $ 1,020.93 $ 1,021.03 (after expenses) on 6/30/11 --------------------------------------------------------------------------------------------------------------------------- Expenses Paid $ 5.66 $ 10.29 $ 9.35 $ 7.00 $ 3.91 $ 3.81 During Period* --------------------------------------------------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.13%, 2.06%, 1.87%, 1.40%, 0.78%, and 0.76% for Class A, Class B, Class C, Class R, Class Y, and Class Z shares respectively, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period).

The accompanying notes are an integral part of these financial statements. 34 Pioneer Cullen Value Fund | Annual Report | 6/30/11 Notes to Financial Statements | 6/30/11 1. Organization and Significant Accounting Policies Pioneer Cullen Value Fund (the Fund) is a series of Pioneer Series Trust III, a Delaware statutory trust. The Fund is registered under the Investment Company Act of 1940 as a diversified open-end management investment company. The investment objective of the Fund is to seek capital appreciation. Current income is a secondary objective. The Fund offers six classes of shares designated as Class A, Class B, Class C, Class R, Class Y and Class Z 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 or Class Z shares. Class B shares convert to Class A shares approximately eight years after the date of purchase. 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. 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 Pioneer Cullen Value Fund | Annual Report | 6/30/11 35 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 at 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 at 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. Trading in foreign securities is substantially completed each day at various times prior to the close of the NYSE. The values of such securities used in computing the net asset value of the Fund's shares are determined as of such times. 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 June 30, 2011, 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 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 is recorded on the accrual basis. Dividend and interest income are reported net of unrecoverable foreign taxes withheld at the applicable country rates. 36 Pioneer Cullen Value Fund | Annual Report | 6/30/11 Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. B. Federal Income Taxes It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income and net realized capital gains, if any, to its shareowners. Therefore, no federal income tax provision is required. Tax years for the prior three fiscal years remain subject to examination by tax authorities. The amounts and characterizations of distributions to shareowners for financial reporting purposes are determined in accordance with federal income tax rules. Therefore, the source 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 June 30, 2011, the Fund had a net capital loss carryforward of $544,714,205, of which, the following amounts will expire between 2016 and 2018 if not utilized: $28,235,355 in 2016, $170,605,729 in 2017 and $345,873,121 in 2018. Included in this amount is $28,235,255 of capital losses which, as a result of the reorganizations with Regions Morgan Keegan Select Value Fund on May 15, 2009 may be subject to limitations imposed by the Internal Revenue Code. Under the recently enacted Regulated Investment Company Modernization Act of 2010, the Fund will be permitted to carry forward capital losses incurred in taxable years beginning after December 22, 2010 for an unlimited period. However, any losses incurred during those future years will be required to be utilized prior to the losses incurred in pre-enactment tax years. As a result of this ordering rule, pre-enactment capital loss carryforwards may be more likely to expire unused. Additionally, post enactment capital losses that are carried forward will retain their character as either short-term or long-term capital losses rather than being considered all short-term as under previous law. The tax character of distributions paid during the years ended June 30, 2011 and June 30, 2010 was as follows: ---------------------------------------------------------------------- 2011 2010 ---------------------------------------------------------------------- Distributions paid from: Ordinary income $58,870,489 $52,155,947 Long-term capital gain -- -- ---------------------------------------------------------------------- Total $58,870,489 $52,155,947 ====================================================================== Pioneer Cullen Value Fund | Annual Report | 6/30/11 37 The following shows the components of distributable earnings on a federal income tax basis at June 30, 2011: ---------------------------------------------------------------------- 2011 ---------------------------------------------------------------------- Distributable earnings: Undistributed ordinary income $ 48,722,707 Capital loss carryforward (544,714,205) Unrealized appreciation 807,537,772 ---------------------------------------------------------------------- Total $311,546,274 ====================================================================== The difference between book-basis and tax-basis unrealized appreciation is attributable to the tax deferral of losses on wash sales. C. 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 $165,420 in underwriting commissions on the sale of Class A shares during the year ended June 30, 2011. D. 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 and Class Z shares do not pay distribution fees. All expenses and fees paid to the transfer agent, Pioneer Investment Management Shareholder Services, Inc. (PIMSS), for its services, are allocated among the classes of shares based on the number of accounts in each class and the ratable allocation of related out-of-pocket expenses (see Note 3). 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, Class Y and Class Z shares can reflect different transfer agent and distribution expense rates. 38 Pioneer Cullen Value Fund | Annual Report | 6/30/11 E. 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. F. 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 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. 2. Management Agreement PIM, a wholly owned indirect subsidiary of UniCredit, manages the Fund's portfolio. Management fees are calculated daily at the annual rate of 0.70% of the Fund's average daily net assets up to $1 billion, 0.65% of the next $1 billion, 0.60% of the next $1 billion, 0.55% of the next $4.5 billion, and 0.525% over $7.5 billion. Prior to January 1, 2011, the Fund's management fee was calculated daily at the annual rate of 0.70% of the Fund's average daily net assets up to $1 billion, 0.65% of the next $1 billion, 0.60% of the next $1 billion, and 0.55% of the excess over $3 billion. For the year ended June 30, 2011, the effective management fee (excluding waivers and/or assumption of expenses) was equivalent to 0.61% of the Fund's average daily net assets. Pioneer Cullen Value Fund | Annual Report | 6/30/11 39 PIM, and not the Fund, pays a portion of the fee it receives from the Fund to Cullen Capital Management LLC as compensation for Cullen's subadvisory services to the Fund. PIM has contractually agreed to limit ordinary operating expenses of the Fund to the extent required to reduce Fund expenses to 1.26%, 1.40% and 1.01% of the average daily net assets attributable to Class A, Class R and Class Y shares, respectively. Expenses waived during the year ended June 30, 2011 are reflected on the Statement of Operations. These expense limitations are in effect through November 1, 2012 for Class R shares, and through June 1, 2012 for Class A and Class Y shares. PIM also contractually agreed to limit ordinary operating expenses of the Fund to the extent required to reduce Fund expenses to 1.25% of the average daily net assets attributable to Class A shares. That expense limitation was in effect through November 1, 2010. Prior to November 1, 2010, Pioneer contractually agreed to limit ordinary operating expenses of the Fund to 2.15% of the average daily net assets attributable to Class B shares. The expense limitation expired on November 1, 2010. There can be no assurance that PIM will extend the expense limitation agreement for a class of shares beyond the dates referred to above.

Distribution and Service Plans The Fund has adopted a distribution plan ("The Plan") pursuant to Rule 12b-1 of the Investment Company Act of 1940 with respect to its Class A, Class B, Class C, and Class R shares. Pursuant to the Plan, the Fund pays PFD 0.25% of the average daily net assets attributable to Class A shares as compensation for personal services and/or account maintenance services or distribution services with regard to Class A shares. Pursuant to the Plan, the Fund also pays PFD 1.00% of the average daily net assets attributable to Class B and Class C shares. The fee for Class B and Class C shares consists of a 0.25% service fee and a 0.75% distribution fee paid as compensation for personal services and/or account maintenance services or distribution services with regard to Class B and Class C shares. Pursuant to the Plan, the Fund further pays PFD 0.50% of the average daily net assets attributable to Class R shares for distribution services. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $28,469 in distribution fees payable to PFD at June 30, 2011. 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, Class Y and Class Z shares) may be subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may be imposed on redemptions of certain net asset value purchases of Class A shares within 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, Class Y or Class Z shares. Proceeds from the CDSCs are paid to PFD. For the year ended June 30, 2011, CDSCs in the amount of $201,204 were paid to PFD. Pioneer Cullen Value Fund | Annual Report | 6/30/11 41 5. Expense Offset Arrangements The Fund has entered into certain expense offset arrangements with PIMSS which may result in a reduction in the Fund's total expenses due to interest earned on cash held by PIMSS. For the year ended June 30, 2011, the Fund's expenses were not reduced under such arrangements. 6. 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. The Funds pay an annual commitment fee for this facility. The commitment fee is allocated among participating Funds based on an allocation schedule set forth in the credit agreement. For the year ended June 30, 2011, the Fund had no borrowings under this agreement. 7. Subsequent Events On August 5, 2011, Standard & Poor's Ratings Services (S&P) lowered its credit rating of the United States' long-term debt from AAA to AA+, with a "Negative" outlook. S&P reaffirmed its top (A-1+) rating on the U.S. government's short-term debt. S&P's downgrade reflects their opinion that the fiscal consolidation plan, that Congress and the Obama Administration agreed to on August 2, 2011 falls short of what would be necessary to stabilize the government's medium-term debt dynamics. The downgrade also reflects S&P's opinion that the effectiveness, stability, and predictability of U.S. policymaking and political institutions have weakened at a time of ongoing fiscal and economic challenges to a degree more than they envisioned when S&P assigned a negative outlook to the rating on April 18, 2011. The long-term effect of the downgrade is uncertain at this time. 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. 42 Pioneer Cullen Value Fund | Annual Report | 6/30/11 Report of Independent Registered Public Accounting Firm To the Board of Trustees and the Shareowners of Pioneer Cullen Value Fund: -------------------------------------------------------------------------------- We have audited the accompanying statement of assets and liabilities of Pioneer Cullen Value Fund (the "Fund"), including the schedule of investments, as of June 30, 2011, 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 periods indicated therein. 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 June 30, 2011 by correspondence with the custodian and brokers. 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 Cullen Value Fund as of June 30, 2011, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the periods indicated therein, in conformity with U.S. generally accepted accounting principles.

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.

For the years ended June 30, 2011 and 2010, there were no services provided to an affiliate that required the Fund's audit committee pre-approval.
