Those were particularly useful guides during the past year, as U.S. and global stock and bond markets grew strongly during the period. In recent months, U.S. equity markets proved resilient in the face of a slowing economy. The Standard & Poor's 500 Stock Index set a record high in late May. The Dow Jones Industrial Average returned 9%, building on a five-year bull market. International developed and emerging markets equities performed even better than U.S. equities, with the MSCI EAFE (developed market) Index returning 11% and the MSCI Emerging Markets Index returning 18% in the first half of 2007. The general U.S. bond market, as measured by the Lehman Brothers Aggregate Bond Index, returned 1% in the first half, as rising bond yields produced price declines that partially offset income earned. The high yield market, as measured by the Merrill Lynch High Yield Bond Master II Index, returned 3%, reflecting its higher yields and continuing investor confidence in the strength of the U.S. economy. The United States has enjoyed a cyclical recovery with strong economic growth. While the growth has slowed recently, we believe that continuing growth at a moderate rate appears to be more likely than a recession. Slowing growth was due in large part to a decline in the rate of new home construction and in part to the lagging effects of rising energy and commodity prices as well as rising short-term interest rates. Slowing economic activity is also due in part to the natural maturation of the cyclical expansion as U.S. factories approach full utilization and the labor market approaches full employment. This slowdown is therefore not entirely unwelcome, as it reduces the threat of higher inflation. The Federal Reserve Board (the Fed) continues to highlight its commitment to keeping inflationary pressures contained. This is in keeping with "best practices" among the world's central banks: low and stable inflation is believed to be the best backdrop for stable economic growth and low average unemployment over the long term. Keeping inflation low is also an important support for stock and bond valuations, and so the Fed's policy is investor-friendly. In Europe, solid GDP growth driven by a positive operating environment for European companies, especially those that are benefiting from strong export markets for their goods and services, is driving unemployment lower and supporting growing consumption. 2 Letter European inflationary pressures appear to be largely under control, with the European Central bank remaining strongly vigilant. Japanese economic growth continues to make progress, and the country has become a more attractive market as deflationary problems recede. Economic growth in emerging market countries remains faster than in the developed world as they continue to "catch up." Leading the way is China, which continues its rise as a world economic power. Looking forward, we believe that the overall climate for equity investors generally will continue to be positive, although valuations are less attractive than they were a year ago, and a correction after a period of strong performance is possible. Rising yields have depressed year-to-date bond returns, but increased the attractiveness of bonds looking forward. Sudden swings in the markets are always to be expected. Just as staying diversified and invested are important investment principles, it is also important to pay attention to asset allocation. As always, we encourage shareholders to work closely with their financial advisor to find the mix of stocks, bonds and money market assets that is aligned to their particular risk tolerance and investment objective.

Rising corporate profits encouraged investors to bid up the prices of almost all equities over the period. In the following interview, James P. Cullen discusses the factors that influenced Pioneer Cullen Value Fund's performance during the 12 months. As President of Cullen Capital Management LLC, Mr. Cullen oversees the team responsible for the daily management of the Fund. Q: How did the Fund perform during the 12 months ending June 30, 2007? A: Cullen Value Fund's Class A shares had a total return of 17.13% at net asset value for the 12 months ending June 30, 2007. During the same period, the Standard & Poor's 500 Index (the S&P 500) rose 20.59%. The average return of the 498 funds in Lipper's Large Cap Value category was 20.81% for the 12 months.

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. Q: What were the principal factors that influenced Fund performance during the 12 months? A: Stock prices kept climbing through virtually the entire fiscal year. While there was some volatility along the way, the 12-month period was remarkably unusual in how greatly the number of positive days in the market outnumbered negative days. Such an environment isn't necessarily conducive to our style, as we focus on stocks with relatively low price-to-earnings ratios compared to the overall market, and we invest in companies with good long-term prospects. Because of our long-term focus, we usually do better during periods when stocks move both up and down, rather than in periods - such as the last 12 months - when momentum seems to be driving equity prices ever higher. 4 Pioneer Cullen Value Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- Q: What were your principal strategies during the period? A: As stock prices kept rising, we began to see the market as overbought - influenced more by speculative behavior than economic fundamentals - and we became somewhat more conservative even as more speculative, smaller-company stocks became fashionable in the market. Among other things, we maintained an emphasis on financials and pharmaceutical stocks - two areas with defensive characteristics which underperformed the market during the persistent rally. We also had a large exposure to the consumer staples sector - another more defensive area. Within consumer staples, we held major positions in global companies such as Unilever, Nestle and Diageo. Our consumer staples weighting was more than twice that of the S&P 500 at the end of the period. We were underweighted in energy for the period, although we built up our position in the sector during the first half of 2007 by adding companies such as Devon Energy, an exploration and production company; Gazprom, the Russian energy giant; and ConocoPhillips, a major integrated oil and energy company. Overall, though, our de-emphasis on energy did not help performance during the period. In general, we made few major changes to the portfolio. For example, while we sold our position in Hartford Financial, we used the proceeds to initiate an investment in another insurance giant, American International Group (AIG), which we liked because of its exposure to international markets. While we reduced our position in financials stocks in 2006, we still maintained a focus on them, emphasizing the larger, diversified financial services corporations that have increased their profiles in international markets. Noteworthy examples include our holdings in shares of Morgan Stanley, Merrill Lynch and JP Morgan Chase. On June 30, 2007, our weighting in the financials sector accounted for approximately 23.5% of Fund assets, which was more than the weighting in the S&P 500. While we have maintained our general weighting in health care - less than that in the S&P 500 - we did make some minor adjustments. For example, in the pharmaceuticals area, while we sold our investment in Sanofi Aventis, we added a position in Wyeth. The decision was based on our belief that in an era 5 Pioneer Cullen Value Fund - -------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 6/30/07 (continued) - -------------------------------------------------------------------------------- of industry consolidation, Wyeth is better positioned as a potential acquisition candidate. Q: What types of individual investments most affected results over the 12 months? A: We had excellent performance from some of the mid-sized companies in our portfolio. For example, Borg-Warner, a manufacturer of highly engineered components, such as drive trains for the automotive industry, gained 39% and was among the top contributors to results. Other mid-sized companies, such as railroad corporation Canadian Pacific and technology manufacturer Arrow Electronics, also turned in excellent results. Other holdings that outperformed the market and added to the Fund's returns included: technology companies Hewlett-Packard and Nokia; consumer staples companies Unilever, Bunge, Diageo and Nestle; insurer MetLife; oil company ConocoPhillips; diversified industrial company 3M; telecommunication services providers Verizon and AT&T; and Cemex, the Mexican-based materials giant. After helping support performance in 2006, our exposure to the diversified financials industry was a drag on performance in 2007, as investors worried about the potential fallout from the problems in the subprime mortgage lending area. However, we continue to like the prospects of our financials holdings and have maintained our positions. Also holding back results was Regions Financial, a banking corporation based in the Southeast. Investors have been leery of acquisitions the company has made, but we think the corporation has sound prospects. Q: What is your investment outlook? A: We plan to continue to pursue our strategy, which is to buy higher-quality companies at inexpensive prices relative to our estimate of long-term prospects. We continue to like the prospects of our consumer staples holdings - many of which have a major presence in the global marketplace. The recent advances in the stock market have been primarily liquidity driven. In other words, new money has entered the market, attracted by robust recent returns, and has driven up stock prices in general. As a consequence, many of the best 6 Pioneer Cullen Value Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- performing stocks have been highly speculative. However, as corporate earnings growth slows, we think the stock market is likely to return to a more normal situation, creating conditions where the types of high-quality value stocks that we emphasize can do well. Many of our holdings boast high dividend yields, which also should be an advantage as the market enters a more uncertain period. Investments in 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.

The performance table and graph do not reflect the deduction of fees and taxes that a shareowner would pay on Fund distributions or the redemption of Fund shares. Pioneer Cullen Value Fund was created through the reorganization of the predecessor Cullen Value Fund on 2/28/05. The performance of Class Y 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 Y shares. 14 Pioneer Cullen Value Fund - -------------------------------------------------------------------------------- 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, 2007** through June 30, 2007. Share Class A B C R Y - ---------------------------------------------------------------------------------------- Beginning Account Value $1,000.00 $1,000.00 $1,000.00 $1,000.00 $1,000.00 Value On 1/1/07** Ending Account Value $1,060.58 $1,055.94 $1,056.45 $ 994.01 $ 1061.83 (after expenses) On 6/30/07 Expenses Paid $ 5.52 $ 10.14 $ 9.53 $ 9.25 $ 3.94 During Period* * Expenses are equal to the Fund's annualized expense ratio of 1.08%, 1.99%, 1.87%, 1.40% and 0.77% for Class A, Class B, Class C, Class R and Class Y shares, respectively, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period) (242/365 for Class R shares). ** 11/1/06 for Class R shares. 15 Pioneer Cullen Value Fund - -------------------------------------------------------------------------------- COMPARING ONGOING FUND EXPENSES (continued) - -------------------------------------------------------------------------------- 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, 2007** through June 30, 2007.

Pioneer Cullen Value Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 6/30/07 - -------------------------------------------------------------------------------- 1. Organization and Significant Accounting Policies Pioneer Cullen Value Fund (the Fund) is a diversified series of Pioneer Series Trust III, a Delaware statutory trust registered under the Investment Company Act of 1940 as an 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 - Class A, Class B, Class C, Class R, and Class Y shares. Class R shares were first publicly offered on November 1, 2006. Each class of shares represents an interest in the same portfolio of investments of the Fund and has equal rights to voting, redemptions, dividends and liquidation, except that the level of transfer agent and distribution fees may differ among classes. Class A, Class B, Class C, and Class R shareowners have exclusive voting rights with respect to the distribution plan for each class. There is no distribution plan for Class Y shares. The Fund's financial statements have been prepared in conformity with U.S. generally accepted accounting principles that require the management of the Fund to, among other things, make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income, expenses and gains and losses on investments during the reporting year. Actual results could differ from those estimates. 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. Information regarding the Fund's principal risks are contained in the Fund's prospectus. Please refer to those documents when considering the Fund's risks. 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 31 Pioneer Cullen Value Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 6/30/07 (continued) - -------------------------------------------------------------------------------- trading on the NYSE. In computing the net asset value, securities 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 generally reported, are valued at the mean between the last bid and asked prices. Securities for which market quotations are not readily available are valued at their fair values as determined by, or under the direction of, 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 also may use the fair value of a security, including a non-U.S. security, when the closing market price on the principal exchange where the security is traded no longer reflects the value of the security. At June 30, 2007 there were no securities fair valued. Temporary cash investments are valued at cost which approximates market 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 exercise of reasonable diligence. Dividend and interest income is recorded on the accrual basis, net of unrecoverable foreign taxes withheld at the applicable country rates. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. B. 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. 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 either from or in excess of net investment income or net 32 Pioneer Cullen Value Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- realized gain on investment transactions, or from paid-in capital, depending on the type of book/tax differences that may exist. The tax character of distributions paid during the years ended June 30, 2007 and June 30, 2006 were as follows: - -------------------------------------------------------------------------------- 2007 2006 - -------------------------------------------------------------------------------- Distributions paid from: Ordinary income $19,583,573 $1,675,415 Long-term capital gain 1,043,128 3,939,226 ----------- ---------- Total $20,626,701 $5,614,641 =========== ========== - -------------------------------------------------------------------------------- The following shows the components of distributable earnings on a federal income tax basis at June 30, 2007 - -------------------------------------------------------------------------------- 2007 - -------------------------------------------------------------------------------- Undistributed ordinary income $ 23,031,983 Undistributed long-term gain 7,606,939 Unrealized appreciation 354,309,534 ------------ Total $384,948,456 ============ - -------------------------------------------------------------------------------- The difference between book-basis and tax-basis unrealized appre ciation 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 UniCredito Italiano S.p.A. (UniCredito Italiano), earned approximately $278,292 in underwriting commissions on the sale of Class A shares during the year ended June 30, 2007. D. Class Allocations 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. Class Y shares are not subject to a distribution plan (see Note 4). Shareowners of each class share all expenses and fees paid to the transfer agent, Pioneer Investment Management Shareholder Services, Inc. (PIMSS), for its 33 Pioneer Cullen Value Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 6/30/07 (continued) - -------------------------------------------------------------------------------- services, which are allocated based on the number of accounts in each class and the ratable allocation of related out-of-pocket expenses (see Note 3). 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 their respective percentage of adjusted net assets at the beginning of the day. 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, at the same time, on the same day, and in the same amount, except that Class A, Class B, Class C, Class R, and Class Y shares can bear different transfer agent and distribution fees. E. Repurchase Agreements With respect to repurchase agreements entered into by the Fund, the value of the underlying securities (collateral), including accrued interest received from counterparties, is required to be at least equal to or in excess of the value of the repurchase agreement at the time of purchase. The collateral for all repurchase agreements is held in safekeeping in the customer-only account of the Fund's custodian, or subcustodians. 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, with the Fund's custodian acting as the lending agent. When entering into a loan, the Fund receives collateral, which is maintained by the custodian and earns income in the form of negotiated lenders' fees. The Fund also continues to receive interest or payments in lieu of dividends 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 loans are secured by collateral of at least 102%, at all times, of the fair value of the securities loaned. The amount of the collateral will be adjusted daily to reflect any price fluctuation in the value of the loaned securities. The Fund has the right under the lending agreements to recover the securities from the borrower on demand. The Fund invests cash collateral in the Securities Lending 34 Pioneer Cullen Value Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- Investment Fund, which is sponsored by Brown Brothers Harriman & Co., the Fund's custodian. 2. Management Agreement PIM, a wholly owned indirect subsidiary of UniCredito Italiano, manages the Fund's portfolio. PIM receives a basic fee that is calculated 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 assets over $3 billion. For the year ended June 30, 2007, the net management fee was equivalent to 0.66% of average daily net assets. PIM, and not the Fund, pays a portion of the fee it receives from the Fund to Cullen LLC as compensation for Cullen's subadvisory services to the Fund. Through November 1, 2009 PIM has agreed not to impose all or a portion of its management fee and to assume other operating expenses of the Fund to the extent necessary to limit Class A expenses to 1.25% of the average daily net assets attributable to Class A shares. Through November 1, 2007, PIM has agreed not to impose all or a portion of its management fee and to assume other operating expenses of the Fund to the extent necessary to limit Class B and Class C expenses to 2.15% of the average daily net assets attributable to Class B and Class C shares, respectively. 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. At June 30, 2007, $113,771 was payable to PIM related to management fees, administrative costs and certain others services, and is included in due to affiliates. 3. Transfer Agent PIMSS, a wholly owned indirect subsidiary of UniCredito Italiano, provides substantially all transfer agent and shareowner services to the Fund at negotiated rates. Included in due to affiliates are $312,346 in transfer agent fees payable to PIMSS at June 30, 2007. 35 Pioneer Cullen Value Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 6/30/07 (continued) - -------------------------------------------------------------------------------- 4. Distribution and Service Plans The Fund adopted a Plan of Distribution with respect to Class A, Class B, Class C, and Class R shares in accordance with Rule 12b-1 of the Investment Company Act of 1940. Pursuant to the Class A Plan, the Fund pays PFD a service fee of up to 0.25% of the average daily net assets attributable to Class A shares in reimbursement of its actual expenditures to finance activities primarily intended to result in the sale of Class A shares. Pursuant to the Class B Plan and the Class C Plan, the Fund pays PFD 1.00% of the average daily net assets attributable to each class of shares. This fee consists of a 0.25% service fee and a 0.75% distribution fee both 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 Class R Plan, the Fund pays PFD 0.50% of the net average daily net assets attributable to Class R shares as compensation for distribution services. 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. Included in due to affiliates is $62,272 in distribution fees payable to PFD at June 30, 2007. In addition, redemptions of each class of shares (except Class R and Class Y shares) may be subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may be imposed on redemptions of certain net asset value purchases of Class A shares within 18 months of purchase. 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 were subject to a CDSC of 1.00%. There is no CDSC for Class R and Class Y shares. Proceeds from the CDSCs are paid to PFD. For the year ended June 30, 2007, CDSCs in the amount of $372,482 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 36 Pioneer Cullen Value Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- June 30, 2007, the Fund's expenses were reduced by $87,527 under such arrangements. 6. Line of Credit Facility The Fund, along with certain other funds in the Pioneer Family of Funds (the Funds), collectively participate in a $200 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 $200 million or the limits set by its prospectus for borrowings. Interest on collective borrowings is payable at the Federal Funds Rate plus 1/2% on an annualized basis. The Funds pay an annual commitment fee for this facility. The commitment fee is allocated among such Funds based on their respective borrowing limits. For the year ended June 30, 2007, the Fund had no borrowings under this agreement. 7. New Pronouncements On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN 48 provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to determine whether the tax positions have a "more-likely-than-not" probability of being sustained by the applicable tax authority. Tax positions deemed to not meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the reporting period in which they are realized. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of no later than June 30, 2008. At this time, management is evaluating the implications of FIN 48 and any impact in the financial statements has not yet been determined. In addition, in September 2006, Statement of Financial Accounting Standards No. 157, Fair Value Measurements (SFAS 157), was issued and is effective for fiscal years beginning after November 15, 2007. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Management is currently evaluating the impact the adoption of SFAS 157 will have on the Fund's financial statement disclosures. 37 Pioneer Cullen Value Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 6/30/07 (continued) - -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (unaudited) For the fiscal year ended June 30, 2007, 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. The Fund intends to designate up to the maximum amount of such dividends allowable under the Act, as taxed at a maximum rate of 15%.

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. The financial highlights for each of the two years in the period ended June 30, 2004 were audited by other auditors whose report, dated August 9, 2004, expressed an unqualified opinion on those financial highlights. 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, 2007, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Pioneer Cullen Value Fund at June 30, 2007, 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 15, 2007 39 Pioneer Cullen Value Fund - -------------------------------------------------------------------------------- TRUSTEES, OFFICERS AND SERVICE PROVIDERS - -------------------------------------------------------------------------------- Investment Adviser Pioneer Investment Management, Inc.

PIONEER FUNDS APPROVAL OF AUDIT, AUDIT-RELATED, TAX AND OTHER SERVICES PROVIDED BY THE INDEPENDENT AUDITOR SECTION I - POLICY PURPOSE AND APPLICABILITY The Pioneer Funds recognize the importance of maintaining the independence of their outside auditors. Maintaining independence is a shared responsibility involving Pioneer Investment Management, Inc ("PIM"), the audit committee and the independent auditors. The Funds recognize that a Fund's independent auditors: 1) possess knowledge of the Funds, 2) are able to incorporate certain services into the scope of the audit, thereby avoiding redundant work, cost and disruption of Fund personnel and processes, and 3) have expertise that has value to the Funds. As a result, there are situations where it is desirable to use the Fund's independent auditors for services in addition to the annual audit and where the potential for conflicts of interests are minimal. Consequently, this policy, which is intended to comply with Rule 210.2-01(C)(7), sets forth guidelines and procedures to be followed by the Funds when retaining the independent audit firm to perform audit, audit-related tax and other services under those circumstances, while also maintaining independence. Approval of a service in accordance with this policy for a Fund shall also constitute approval for any other Fund whose pre-approval is required pursuant to Rule 210.2-01(c)(7)(ii). In addition to the procedures set forth in this policy, any non-audit services that may be provided consistently with Rule 210.2-01 may be approved by the Audit Committee itself and any pre-approval that may be waived in accordance with Rule 210.2-01(c)(7)(i)(C) is hereby waived. Selection of a Fund's independent auditors and their compensation shall be determined by the Audit Committee and shall not be subject to this policy.
