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 | Semiannual Report | 12/31/09 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 | Semiannual Report | 12/31/09 3 Portfolio Management Discussion | 12/31/09 The second half of 2009 saw stocks continue the robust rally that began in March, with the best performance coming from highly-speculative, momentum-driven companies that had fallen hardest in the market declines of 2008. In the following interview, James P. Cullen, President of Cullen Capital Management, LLC, discusses the factors that influenced the performance of Pioneer Cullen Value Fund during the six months ended December 31, 2009. Mr. Cullen oversees the team responsible for the daily management of the Fund. Q How did the Fund perform during the final six months of 2009? A Cullen Value Fund Class A shares returned 19.01% at net asset value during the six months ended December 31, 2009, while the Fund's benchmark, the Standard & Poor's 500 Index (the S&P 500), returned 22.57%. Over the same six-month period, the average return of the 532 funds in Lipper's Large Cap Value category was 21.55%. Q What were the principal factors influencing the Fund's performance over the six months ended December 31, 2009? A Our emphasis on low-priced, fundamentally-sound stocks led to the Fund's underperformance relative to the S&P 500 and its Lipper peer group. While our stock selections participated in the dynamic market surge that began after stock prices hit their lows in early March 2009, they did not keep up with the market averages. The market rally was led by stocks of companies with little earnings, weak balance sheets and low dividends. These highly- speculative stocks, many selling at less than $5 per share (sometimes referred to as "junk stocks"), produced returns several times greater than stocks selling for more than $50 per share. The performance disparity often occurred because short-sellers, who had borrowed shares of very low-priced companies to bet on their price declines, moved in droves to buy the beaten-down stocks and cover their positions. The outperformance by low- quality stocks during the first months of the stock price rebound was, in fact, consistent with historical trends that we've seen as markets begin to recover from deep downturns. Throughout the six months ended December 31, 2009, we held to our established strategy for the Fund, focusing on the long-term and emphasizing solid companies with low prices and high stock dividends. The strategy had helped the Fund outperform when stocks fell the hardest before the market recovery, but it led to lagging results relative to the benchmark, it's Lipper peer group and other market indices in 2009. 4 Pioneer Cullen Value Fund | Semiannual Report | 12/31/09 Q How did you position the Fund during the six months ended December 31, 2009, and how did that affect performance results? A We did not deviate from our discipline and we remained focused on the longer-term horizon. We emphasized investments in quality, fundamentally- sound corporations that produce earnings and pay dividends. Based on our analysis of previous post-recession market rallies, we believe this disciplined approach is the best way to achieve competitive performance over the five years following a severe market recession. Overall stock selection for the Fund was good. Nevertheless, our discipline led us to overweight the Fund to some of the more defensive groups that lagged in the market's sharp recovery. The portfolio was underexposed to the more volatile, momentum-driven stocks that generated the highest returns in the recovery rally. The Fund had overweighted positions in consumer staples and industrials, with underweighted exposure to information technology, consumer discretionary, financials and energy. The Fund's below-benchmark investments in the information technology and consumer discretionary sectors were major factors in its relative underperformance during the six-month period. In addition, the Fund held a cash position of about 7% of net assets, and that did not help returns in a rising stock market. During the six months, we added an investment in a former Fund holding, PetroChina, an energy company whose share price had fallen from its 2008 highs and which was well-positioned to benefit from the robust growth in China. To add to its attributes, PetroChina has earned 15% of its profits from its natural gas transmission line, which we believe has great potential as China moves to cleaner energy sources and less reliance on coal-operated facilities. We also acquired a smaller position in Fluor, the U.S.-based infrastructure development company with heavy involvement in emerging markets. At the same time, we added to the Fund's investments in financials stocks. At December 31, 2009, the largest Fund positions were: Microsoft, Oracle, Covidien, 3M, Disney, Unilever, Devon Energy, JPMorgan Chase, United Technologies and Boeing. Q What types of investments most influenced the Fund's results over the six months ended December 31, 2009? A The single largest contributor to the Fund's results during the six months was 3M, the diversified company that manufactures a variety of products for industrial and consumer markets. The Fund's position in Disney, the entertainment and media corporation, also helped support results, as did exposures to Unilever, the global consumer products company, and United Pioneer Cullen Value Fund | Semiannual Report | 12/31/09 5 Technologies, a diversified industrials corporation. In information technology, Microsoft and Hewlett-Packard both made noteworthy contributions to the Fund's performance over the six-month period. The lack of any Fund exposure to troubled financial giant Citigroup hurt performance during the six months, as its share price appreciated sharply after the corporation received government assistance. Investments that held back the Fund's results during the period included telecommunication equipment company Nokia; Ensco International, a corporation specializing in offshore oil and natural gas drilling; and BorgWarner, the manufacturer of highly engineered automotive parts that had performed strongly during the first half of 2009. Q What is your investment outlook? A We believe we see excellent opportunity potentially to achieve competitive results with a disciplined focus on value stocks. We have analyzed past records, focusing on what has tended to happen in the five years subsequent to periods marked by major declines in both corporate earnings and stock market prices. We have found that even though highly-speculative, momentum-driven stocks tend to do well during short-term market recoveries, the shares of value companies that have solid earnings and that pay healthy dividends have tended to fare better over longer periods. Market history indicates that long-term investors eventually return to the market following the initial recovery period. These longer-term investors have tended to prefer companies that both earn profits and pay dividends. While the market may pause after its strong ascent in 2009, we believe the overall backdrop for stocks remains attractive. Stock prices should receive support from the continuing global economic expansion and the resulting improvement in corporate earnings. We think stocks, in general, continue to be reasonably priced and there remains a great deal of money sitting on the sidelines, waiting to be deployed in the markets. We believe the prospects for a disciplined value approach to the market remain excellent, especially when taking the longer-term view.

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 shown for periods prior to the inception of Class Y shares reflects the NAV performance of the Fund's A shares. The performance does not reflect differences in expenses, including the Rule 12b-1 fees applicable to A shares. Since fees for A shares are generally higher than those of Y shares, the performance for Y shares prior to their inception would have been higher than that 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.

Pioneer Cullen Value Fund | Semiannual Report | 12/31/09 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 July 1, 2009 through December 31, 2009. - ----------------------------------------------------------------------------------------------------------------- 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 7/1/09 - ----------------------------------------------------------------------------------------------------------------- Ending Account Value $ 1,171.30 $ 1,185.20 $ 1,185.50 $ 1,189.20 $ 1,193.20 $ 1,192.70 (after expenses) on 12/31/09 - ----------------------------------------------------------------------------------------------------------------- Expenses Paid $ 6.40 $ 11.24 $ 10.58 $ 7.73 $ 4.04 $ 4.26 During Period* - ----------------------------------------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.17%, 2.04%, 1.92%, 1.40% 0.73%, and 0.77% for Class A, Class B, Class C, Class R, Class Y, and Class Z respectively, multiplied by the average account value over the period, multiplied by 184/365 (to reflect the one-half year period). 16 Pioneer Cullen Value Fund | Semiannual Report | 12/31/09 Hypothetical Example for Comparison Purposes The table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads) that are charged at the time of the transaction. Therefore, the table below is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher.

Organization and Significant Accounting Policies Pioneer 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. 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 my 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 Fund to, among other things, make estimates and assumptions that affect the Pioneer Cullen Value Fund | Semiannual Report | 12/31/09 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 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 December 31, 2009, there were no securities that were valued using fair value methods (other than securities that were valued using prices supplied by independent pricing services). 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. 36 Pioneer Cullen Value Fund | Semiannual Report | 12/31/09 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 tax character of current year distributions payable will be determined at the end of the current fiscal year. The tax character of distributions paid during the year ended June 30, 2009 was as follows: -------------------------------------------------- 2009 -------------------------------------------------- Distributions paid from: Ordinary income $39,020,477 Long-term capital gain -- -------------------------------------------------- Total $39,020,477 ================================================== The following shows the components of distributable earnings on a federal income tax basis at June 30, 2009: -------------------------------------------------- 2009 -------------------------------------------------- Distributable earnings: Undistributed ordinary income $ 37,389,606 Capital loss carryforward (265,784,298) Post-October loss deferred (288,208,473) Unrealized depreciation (527,025,168) -------------------------------------------------- Total $(1,043,628,333) ================================================== 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 approximately $148,002 in underwriting commissions on the sale of Class A shares during the six months ended December 31, 2009. Pioneer Cullen Value Fund | Semiannual Report | 12/31/09 37 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 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 38 Pioneer Cullen Value Fund | Semiannual Report | 12/31/09 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 the next business 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 six months ended December 31, 2009, 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, 2010 for Class A, Class B, Class C and Class R shares, and through May 15, 2012 for Class Y shares. 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 $125,237 in management fees, administrative costs and certain others reimbursements payable to PIM at December 31, 2009. 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. Pioneer Cullen Value Fund | Semiannual Report | 12/31/09 39 For the six months ended December 31, 2009, such out of pocket expenses by class of shares were as follows: - ---------------------------------------------------- Shareholder Communications - ---------------------------------------------------- Class A $1,276,373 Class B 34,772 Class C 219,095 Class R 16,994 Class Y 388,159 Class Z 1,288 - ---------------------------------------------------- Total $1,936,681 ==================================================== Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $629,846 in transfer agent fees and out-of-pocket reimbursements payable to PIMSS at December 31, 2009. 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 $31,971 in distribution fees payable to PFD at December 31, 2009. 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. 40 Pioneer Cullen Value Fund | Semiannual Report | 12/31/09 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 six months ended December 31, 2009, CDSCs in the amount of $123,147 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 six months ended December 31, 2009, 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 six months ended December 31, 2009, the Fund had no borrowings under this agreement. 7. Reorganization Information On May 8, 2009, beneficial owners of Regions Morgan Keegan Select Value Fund approved a proposed Agreement and Plan of Reorganization that provided for the reorganization listed below. This tax-free reorganization was accomplished on May 15, 2009 ("Closing Date"), by exchanging the assets and stated liabilities of Regions Morgan Keegan Select Value Fund for shares of Pioneer Cullen Value Fund.

Subsequent Events In preparing these financial statements, PIM has evaluated the impact of all events and transactions for potential recognition or disclosure through February 22, 2010, and has determined that there were no subsequent events requiring recognition or disclosure in the financial statements. 42 Pioneer Cullen Value Fund | Semiannual Report | 12/31/09 Approval of Investment Advisory and Sub-Advisory Agreements Pioneer Investment Management, Inc. (PIM) serves as the investment adviser to Pioneer Cullen Value Fund (the Fund) pursuant to an investment advisory agreement between PIM and the Fund. PIM has retained Cullen Capital Management, LLC (Cullen Capital) to serve as the sub-adviser to the Fund pursuant to a sub-advisory agreement between PIM and the sub-adviser. In order for PIM and Cullen Capital to remain the investment adviser and sub-adviser of the Fund, respectively, the Trustees of the Fund must determine annually whether to renew the investment advisory agreement and the sub-advisory agreement for the Fund. The contract review process began in March 2009 as the Trustees of the Fund agreed on, among other things, an overall approach and timeline for the process. In July 2009, the Trustees approved the format of the contract review materials and submitted their formal request to PIM to furnish information necessary to evaluate the terms of the investment advisory agreement and the sub-advisory agreement. The contract review materials were provided to the Trustees in August 2009. After reviewing and discussing the materials, the Trustees submitted a request for additional information to PIM in September 2009, and materials were provided in response to this request. Meetings of the independent Trustees of the Fund were held in July, September, October, and November, 2009 to review and discuss the contract review materials. In addition, the Trustees took into account the information related to the Fund provided to the Trustees at each regularly scheduled meeting. At a meeting held on November 10, 2009, based on their evaluation of the information provided by PIM, the sub-adviser and third parties, the Trustees of the Fund, including the independent Trustees voting separately, unanimously approved the renewal of the investment advisory agreement and the sub-advisory agreement for another year. In considering the renewal of the investment advisory agreement and the sub-advisory agreement, the Trustees considered various factors that they determined were relevant, including the factors described below. The Trustees did not identify any single factor as the controlling factor in determining to approve the renewal of the agreements. Nature, Extent and Quality of Services The Trustees considered the nature, extent and quality of the services that had been provided by PIM and the sub-adviser to the Fund, taking into account the investment objective and strategy of the Fund. The Trustees reviewed the terms of the investment advisory agreement and the sub-advisory agreement. The Trustees also reviewed the sub-adviser's investment approach for the Fund, its research process and its process for trade execution. The Trustees considered Pioneer Cullen Value Fund | Semiannual Report | 12/31/09 43 the resources of PIM and the sub-adviser and the personnel of PIM and the sub-adviser who provide investment management services to the Fund. The Trustees considered the non-investment resources and personnel of PIM involved in PIM's services to the Fund, including PIM's compliance and legal resources and personnel. The Trustees also considered the substantial attention and high priority given by PIM's senior management to the Pioneer fund complex. The Trustees considered that PIM supervises and monitors the performance of the Fund's service providers (including the sub-adviser) and provides the Fund with personnel (including Fund officers) and other resources that are necessary for the Fund's business management and operations. The Trustees also considered that, as administrator, PIM is responsible for the administration of the Fund's business and other affairs. The Trustees considered the fees paid to PIM for the provision of administration services. Based on these considerations, the Trustees concluded that the nature, extent and quality of services that had been provided by PIM and the sub-adviser to the Fund were satisfactory and consistent with the terms of the investment advisory agreement and the sub-advisory agreement. Performance of the Fund The Trustees considered the performance results of the Fund over various time periods. They reviewed information comparing the Fund's performance with the performance of its peer group of funds as classified by Morningstar, Inc. (Morningstar), an independent provider of investment company data, and with the performance of the Fund's benchmark index. The Trustees considered that the Fund's annualized total return was in the second quintile of its Morningstar category for the one year period ended June 30, 2009 and in the first quintile of its Morningstar category for the three year period ended June 30, 2009. (In all quintile rankings referred to throughout this disclosure, first quintile is most favorable to the Fund's shareowners. Thus, highest relative performance would be first quintile and lowest relative expenses would also be first quintile.) The Trustees concluded that the investment performance of the Fund was satisfactory. Management Fee and Expenses The Trustees considered information showing the fees and expenses of the Fund in comparison to the management fees of its peer group of funds as classified by Morningstar and the expense ratios of a peer group of funds selected on the basis of criteria determined by the independent Trustees for this purpose using data provided by Strategic Insight Mutual Trust Research and Consulting, LLC (Strategic Insight), an independent third party. The Trustees also considered that PIM, not the Fund, paid the sub-adviser pursuant to the sub-advisory agreement. The Trustees evaluated both the fee under the 44 Pioneer Cullen Value Fund | Semiannual Report | 12/31/09 sub-advisory agreement and the portion of the fee under the investment advisory agreement retained by PIM. The Trustees considered that the Fund's management fee for the twelve months ended June 30, 2009 was in the second quintile relative to the management fees paid by other funds in its Morningstar peer group for the comparable period. The Trustees also considered that the Fund's expense ratio for the twelve months ended June 30, 2009 was in the third quintile relative to its Strategic Insight peer group for the comparable period. The Trustees considered the breakpoints in the management fee schedule and the reduced fee rates above certain asset levels. The Trustees also reviewed management fees charged by PIM to its institutional and other clients. In evaluating the fees associated with PIM's client accounts, the Trustees took into account the respective demands, resources and complexity associated with the Fund and client accounts. The Trustees noted that in some instances the fee rates for those clients were lower than the management fee for the Fund and considered that, under the investment advisory agreement with the Fund, PIM performs additional services for the Fund that it does not provide to those other clients or services that are broader in scope, including oversight of the Fund's other service providers and activities related to compliance and the extensive regulatory and tax regimes to which the Fund is subject. The Trustees also reviewed management fees charged by the sub- adviser to its other clients. The Trustees noted that in most instances the fee rates for those clients were higher than the sub-advisory fees paid to the sub- adviser with respect to the Fund. The Trustees concluded that the management fee payable by the Fund to PIM, as well as the fees payable by PIM to the sub-adviser of the Fund, were reasonable in relation to the nature and quality of the services provided by PIM and the sub-adviser. The Trustees also concluded that the Fund's expense ratio was reasonable taking into account the nature and quality of services provided by PIM and the sub-adviser. Profitability The Trustees considered information provided by PIM regarding the profitability of PIM with respect to the advisory services provided by PIM to the Fund, including the methodology used by PIM in allocating certain of its costs to the management of the Fund. The Trustees also considered PIM's profit margin in connection with the overall operation of the Fund. The Trustees further considered the sub-advisory fees received by the sub-adviser with respect to the Fund and the percentage that such fees represented of the sub-adviser's overall revenues (for the 12-month period ended December 31, 2008). They further reviewed the financial results realized by PIM and its affiliates from non-fund businesses. The Trustees considered PIM's profit margins with respect to the Fund in comparison to the limited industry data available Pioneer Cullen Value Fund | Semiannual Report | 12/31/09 45 and noted that the profitability of any adviser was affected by numerous factors, including its organizational structure and method for allocating expenses. The Trustees concluded that the profit margins with respect to the management of the Fund were not unreasonable. Economies of Scale The Trustees considered PIM's views relating to economies of scale in connection with the Pioneer Funds as fund assets grow and the extent to which any such economies of scale are shared with funds and fund shareholders. The Trustees recognize that economies of scale are difficult to identify and quantify and that, among other factors that may be relevant, are the following: fee levels, expense subsidization, investment by PIM in research and analytical capabilities and PIM's commitment and resource allocation to the Funds. The Trustees noted that profitability also may be an indicator of the availability of any economies of scale, although profitability may vary for other reasons particularly, for example during the difficult year in 2008 for financial markets, as the level of services was maintained notwithstanding a significant decline in PIM's fee revenues from the Funds. Accordingly, the Trustees concluded that economies of scale, if any, were being appropriately shared with the Fund. Other Benefits The Trustees considered the other benefits to each of PIM and the sub-adviser from its relationship with the Fund. The Trustees considered the character and amount of fees paid by the Fund, other than under the investment advisory agreement, for services provided by PIM and its affiliates. The Trustees further considered the revenues and profitability of PIM's businesses other than the fund business. The Trustees also considered the benefits to the Fund and to the sub-adviser and its affiliates from the use of "soft" commission dollars generated by the Fund to pay for research and brokerage services. The Trustees considered the intangible benefits to each of PIM and the sub-adviser by virtue of its relationship with the Fund and the other Pioneer funds. The Trustees concluded that the receipt of these benefits was reasonable in the context of the overall relationship between each of PIM and the sub-adviser and the Fund. Conclusion After consideration of the factors described above as well as other factors, the Trustees, including all of the independent Trustees, concluded that each of the investment advisory agreement between PIM and the Fund and the sub-advisory agreement between PIM and the sub-adviser, including the fees payable thereunder, was fair and reasonable and voted to approve the proposed renewal of each of the investment advisory agreement and the sub-advisory agreement for the Fund. 46 Pioneer Cullen Value Fund | Semiannual Report | 12/31/09 Trustees, Officers and Service Providers Trustees John F.

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.
