This is a welcome relief, and we are generally optimistic about the prospects for the economy going forward. Still, challenges remain. Unemployment is high; consumer demand and loan growth are weak; and housing has not returned to normal. At Pioneer, we have long advocated the benefits of investing for the long term. This strategy has generally performed well for many investors. Those who remained invested in the market during the downturn have most likely seen their portfolios start to recover over the past year, as the Dow Jones Industrial Average climbed back from the depressed levels we saw in early 2009. Many bond investors have similarly seen a strong rebound, with a broad-based recovery occurring across many different fixed-income asset classes. The riskiest asset classes, such as high-yield bonds, outperformed other fixed-income asset classes during most of 2009. At Pioneer, we are not changing the approach to investing that we have used for more than 80 years. We remain focused on company fundamentals and risk management. Our investment process is based on careful research into individual companies, quantitative analysis, and active portfolio management. This three-pillared process, which we apply to each of our portfolios, is supported by an integrated team approach and is designed to carefully balance risk and reward. While we see potential opportunities for making money in many corners of the markets around the globe, it takes research and experience to separate solid investment opportunities from speculation. Following this difficult period, many investors are rethinking their approach to investing and risk management. Some are questioning whether the basic investment principles they were taught in the past are still useful in today's markets. Complicating matters is that financial markets remain unpredictable. Our advice, as always, is to work closely with a trusted financial advisor to discuss your goals and work together to develop an investment strategy that meets your individual needs. There is no single best strategy that works for every investor. 2 Pioneer Cullen Value Fund | Annual Report | 6/30/10 We invite you to learn more about Pioneer and our time-tested approach to investing by consulting with your financial advisor or visiting us online at www.pioneerinvestments.com. 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 Cullen Value Fund | Annual Report | 6/30/10 3 Portfolio Management Discussion | 6/30/10 Large-cap stocks rallied over most of the 12 months ended June 30, 2010, before falling sharply in the final weeks of the period as confidence about the strength of the economic recovery began to falter and new doubts began to grow. In the following discussion, James P. Cullen, President of Cullen Capital Management, LLC, reviews the factors that influenced the performance of Pioneer Cullen Value Fund during the 12-month period. Mr. Cullen oversees the team responsible for the daily management of the Fund. Q How did the Fund perform during the 12 months ended June 30, 2010? A Pioneer Cullen Value Fund Class A shares returned 8.95% at net asset value over the 12 months ended June 30, 2010, while the Fund's benchmark, the Standard & Poor's 500 Index (the S&P 500), returned 14.43%. Over the same 12-month period, the average return of the 521 mutual funds in Lipper's Large Cap Value category was 12.88%. Q What were the principal factors affecting the Fund's performance over the 12 months ended June 30, 2010? A The Fund lagged the benchmark S&P 500 Index's results early in the period because of our consistent emphasis on value stocks of companies that are fundamentally strong. We continued to avoid the stocks of companies we viewed as having more risk, even though such stocks outperformed during the market surge of 2009 and early 2010. Later in the annual reporting period, the Fund's positions in corporations with exposure to the euro held back performance results as the debt crisis in Greece and several other countries generally undermined confidence in European stocks. In addition, several of the portfolio's financial holdings performed poorly, also holding back relative performance. Despite the underperformance of the Fund in recent months, we remain confident in our investment style and of the importance of staying disciplined, even in the face of short-term market moves that appear to reward approaches that are less consistent. Historically, the capital markets often have been unpredictable for one-to-two-year periods. Over five- and 10-year time spans, however, value-oriented approaches generally have produced very good returns. We have kept the Fund's investments focused on the longer term, with an emphasis on low-priced stocks of companies with strong fundamentals and high dividends. During the past few months, in fact, we have placed additional emphasis on stocks with high dividends, as they seem to offer the best relative value, both with respect to other stock classes and to alternative investments, such as bonds. We believe history has 4 Pioneer Cullen Value Fund | Annual Report | 6/30/10 shown that a long-term approach that focuses on company fundamentals is the best way to achieve strong relative performance in the five years following a recession. Q What types of investments most influenced the Fund's performance over the 12 months ended June 30, 2010? A We typically allocate approximately 20% of the Fund's portfolio to companies exposed to the euro, but that exposure was a performance detractor during a period when euro-exposed stocks sold off following the debt crisis hitting several European countries. The stocks of some solid companies either based in Europe or with significant European interests were affected. Euro-exposed companies that held back the Fund's results during the 12-month period included: German chemical company A.G. Bayer; Russian energy giant Gazprom; and Finland-based telecommunications equipment company Nokia. We sold the Fund's position in Nokia. In addition, the Fund's investments in the financials sector did not fare well over the 12-month period, even though we underweighted the group. Financials sector investments that lagged included investment banks Goldman Sachs and Morgan Stanley and diversified banking giant Citigroup. Information technology holdings that produced just flat results for the Fund in a generally higher market included software leaders Microsoft and Oracle. Stock selections in the industrials and energy groups tended to have positive effects on the Fund's results over the 12 months ended June 30, 2010. In the industrial sector, three very strong performers were Boeing, a leader in the development and manufacture of aircraft; United Technologies, the diversified corporation that enjoyed strong demand for its products in China; and 3M, which produces a variety of products for industrial and consumer markets. Two additional solid contributors to Fund performance were railroads Canadian Pacific and Canadian National. Although the Fund's financials investments did not fare well overall, one holding that did help performance was insurer Chubb. Three European-based companies that better withstood the sharp decline in the euro during the period were global consumer companies Nestle, Unilever and Diageo. From other sectors, the top-performing Fund holding was global media and entertainment leader Walt Disney, whose earnings received a boost from its fast-growing English language education operations in China. Q What is your investment outlook? A While we do not focus on short-term economic or market forecasts, we believe that there is more reason to have a positive economic view than recent downturns would appear to suggest. We think the market may have entered a period of consolidation, which history tells us is typically followed by a brisk revival. Stock market valuations appear inexpensive relative to Pioneer Cullen Value Fund | Annual Report | 6/30/10 5 earnings and very attractive relative to bonds. After a period of restructuring and cost-cutting, corporations in general appear go be in solid financial shape, with relatively low debt levels and large amounts of cash. We are particularly interested in investing the Fund in companies paying higher-than-average dividends, as these corporations usually are in very strong financial positions. While high unemployment continues to be a drag on the economy and the market, job creation typically is a lagging indicator as economies move out of recession. Moreover, it is worth noting that we are approaching the year 2011 -- the year before a presidential election. Pre-election years historically have been very good years for the market. Overseas, we think the markets may have over-reacted to the European debt crisis, and we believe many European companies are selling at prices that appear very attractive relative to U.S. companies with comparable earnings.

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. 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. Performance shown for the period from February 28, 2005, to the inception of Class Z shares on November 1, 2008, 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 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. Pioneer Cullen Value Fund was created through the reorganization of the predecessor Cullen Value Fund on February 28, 2005. The performance shown for Class Z shares of the Fund from July 1, 2000, to February 25, 2005, is the performance of Cullen Value Fund's single class, which has not been restated to reflect any differences in expenses. Cullen Value Fund had higher expenses than those of the Fund's Class Z shares. 14 Pioneer Cullen Value Fund | Annual Report | 6/30/10 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, 2010, through June 30, 2010. - ----------------------------------------------------------------------------------------------------------- Share Class A B C R Y Z - ----------------------------------------------------------------------------------------------------------- Beginning Account Value $1,000.00 $1,000.00 $1,000.00 $1,000.00 $1,000.00 $1,000.00 Value on 1/1/10 - ----------------------------------------------------------------------------------------------------------- Ending Account Value $1,089.50 $1,080.30 $1,081.60 $1,087.50 $1,094.70 $1,093.60 (after expenses) on 6/30/10 - ----------------------------------------------------------------------------------------------------------- Expenses Paid $ 5.56 $ 9.72 $ 9.10 $ 6.65 $ 3.57 $ 3.80 During Period* - ----------------------------------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.17%, 2.05%, 1.92%, 1.40%, 0.75%, and 0.80% 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). Pioneer Cullen Value Fund | Annual Report | 6/30/10 15 Hypothetical Example for Comparison Purposes The table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads) that are charged at the time of the transaction. Therefore, the table below is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher.

The accompanying notes are an integral part of these financial statements. Pioneer Cullen Value Fund | Annual Report | 6/30/10 33 Notes to Financial Statements | 6/30/10 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 five classes of shares designated as Class A, Class C, Class R, Class Y and Class Z shares. Class Z shares were first publicly offered on November 1, 2008. 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 it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. The Fund's prospectuses contain unaudited information regarding the Fund's principal risks. Please refer to those documents 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 34 Pioneer Cullen Value Fund | Annual Report | 6/30/10 Fund to, among other things, make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income, expenses and gains and losses on investments during the reporting year. 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, 2010, there were no securities that were valued using fair value methods. 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. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. Pioneer Cullen Value Fund | Annual Report | 6/30/10 35 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 sources of the Fund's distributions may be shown in the accompanying financial statements as from or in excess of net investment income or as from net realized gain on investment transactions, or as from paid-in capital, depending on the type of book/tax differences that may exist. The Fund has elected to defer $68,618,964 in capital losses recognized between November 1, 2009 and June 30, 2010 to its fiscal year ending June 30, 2011. At June 30, 2010, the Fund had a net capital loss carryforward of $611,657,419, of which the following amounts will expire between 2015 and 2018 if not utilized; $6,224,159 in 2015, $45,050,496 in 2016, $214,509,643 in 2017 and $345,873,121 in 2018. The tax character of distributions paid during the years ended June 30, 2010, and June 30, 2009 were as follows: ----------------------------------------------------------------------------- 2010 2009 ----------------------------------------------------------------------------- Distributions paid from: Ordinary income $52,155,947 $39,020,477 Long-term capital gain -- -- ----------------------------------------------------------------------------- Total $52,155,947 $39,020,477 ============================================================================= The following shows the components of distributable earnings on a federal income tax basis at June 30, 2010: ----------------------------------------------------------------------------- 2010 ----------------------------------------------------------------------------- Distributable earnings: Undistributed ordinary income $ 38,347,909 Capital loss carryforward (611,657,419) Post-October loss deferred (68,618,964) Unrealized depreciation (136,485,303) ----------------------------------------------------------------------------- Total $(778,413,777) ============================================================================= The difference between book-basis and tax-basis unrealized depreciation is attributable to the tax deferral of losses on wash sales. 36 Pioneer Cullen Value Fund | Annual Report | 6/30/10 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 approximately $269,761 in underwriting commissions on the sale of Class A shares during the year ended June 30, 2010. 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. 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 fair 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 Pioneer Cullen Value Fund | Annual Report | 6/30/10 37 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 fair 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 fair value of the loaned securities. If the required market value of the collateral is less than the fair 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, and 0.55% of the excess over $3 billion. For the year ended June 30, 2010, the effective management fee (net of waivers and/or assumption of expenses) was equivalent to 0.62% of the Fund's average daily net assets. 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 1.25%, 2.15%, 2.15%, 1.40% and 1.01% of the average daily net assets attributable to Class A, Class B, Class C, Class R and Class Y shares, respectively. These expense limitations are in effect through November 1, 2011 for Class A, Class B, Class C, and Class R shares, and through June 1, 2012 for Class Y shares. In addition, Pioneer has contractually agreed to limit ordinary operating expenses to the extent required to reduce fund expenses to 1.26% of the average daily net assets attributable to Class A shares through June 1, 2012. However, there can be no assurance that Pioneer will extend the expense limitation agreement beyond the dates referred to above. In addition, under the management and administration agreements, certain other services and costs, including accounting, regulatory reporting and insurance premiums, are paid by the Fund as administrative reimbursements. 38 Pioneer Cullen Value Fund | Annual Report | 6/30/10 Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $81,383 in management fees, administrative costs and certain other reimbursements payable to PIM at June 30, 2010. 3. Transfer Agent PIMSS, a wholly owned indirect subsidiary of UniCredit, provides substantially all transfer agent and shareowner services to the Fund at negotiated rates. In addition, the Fund reimburses PIMSS for out-of-pocket expenses incurred by PIMSS related to shareholder communications activities such as proxy and statement mailings, outgoing phone calls and omnibus relationship contracts. For the year ended June 30, 2010, such out-of-pocket expenses by class of shares were as follows: Shareholder Communications Class A $2,799,577 Class B 75,461 Class C 455,998 Class R 34,897 Class Y 1,115,467 Class Z 12,431 - -------------------------------------------------------------------------------- Total $4,493,831 ================================================================================ Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $881,928 in transfer agent fees and out-of-pocket reimbursements payable to PIMSS at June 30, 2010. 4. Distribution and Service Plans The Fund has adopted a Distribution Plan pursuant to Rule 12b-1 of the Investment Company Act of 1940 with respect to its Class A, Class B, Class C, and Class R shares. Pursuant to the Plan, the Fund pays PFD 0.25% of the average daily net assets attributable to Class A shares as compensation for personal services and/or account maintenance services or distribution services with regard to Class A shares. Pursuant to the Plan, the Fund also pays PFD 1.00% of the average daily net assets attributable to Class B and Class C shares. The fee for Class B and Class C shares consists of a 0.25% service fee and a 0.75% distribution fee paid as compensation for personal services and/or account maintenance services or distribution services with regard to Class B and Class C shares. Pursuant to the Plan, the Fund further pays PFD 0.50% of the net 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 $28,052 in distribution fees payable to PFD at June 30, 2010. The Fund also has adopted a separate service plan for Class R shares (Service Plan). The Service Plan authorizes the Fund to pay securities dealers, plan Pioneer Cullen Value Fund | Annual Report | 6/30/10 39 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, 2010, CDSCs in the amount of $278,522 were paid to PFD. 5. Expense Offset Arrangements The Fund has entered into certain expense offset arrangements with PIMSS resulting in a reduction in the Fund's total expenses due to interest earned on cash held by PIMSS. For the year ended June 30, 2010, 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, 2010, the Fund had no borrowings under this agreement. 7.

Pioneer Cullen Value Fund | Annual Report | 6/30/10 41 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, 2010, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the 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, 2010 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, 2010, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the periods indicated therein, in conformity with U.S. generally accepted accounting principles. /s/ Ernst & Young LLP Boston, Massachusetts August 24, 2010 42 Pioneer Cullen Value Fund | Annual Report | 6/30/10 ADDITIONAL INFORMATION (unaudited) For the year ended June 30, 2010, certain dividends paid by the Fund may be subject to a maximum tax rate of 15%, as provided for by the Jobs and Growth Tax Relief Reconciliation Act (the Act) of 2003.

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.
