These were particularly useful guides during the past year, as U.S. and global stock and bond markets grew strongly during this period. The markets were supported by relatively low short-term interest rates and generally strong economies around the globe. The U.S. stock market, as measured by the Standard & Poor's 500 Index, gained approximately 10% over the 12 months ending March 31, 2007. European and emerging markets equities performed even better, with indexes in those regions rising more than 20% over the same period. The U.S. bond market, despite growing concerns about the health of the U.S. mortgage industry, gained roughly 7% over the past 12 months, as measured by the Lehman Aggregate Bond Index. The high yield market, as measured by the Merrill Lynch High Yield Bond Master II Index, returned nearly 12%. We believe that the climate for investors generally will continue to be positive. While still strong, the U.S. economy has slowed. This was due in part to the lagging effects of rising energy and commodity prices, rising short-term interest rates from historically low levels, and the effect of U.S. factories approaching full utilization. We have enjoyed a cyclical recovery with strong economic growth, and the U.S. economy now appears to be slowing to a rate that may be more sustainable. The Federal Reserve Board has indicated a reduced likelihood of future rate hikes, and 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. In Europe, healthy labor markets are supporting growing consumption and rising GDP growth. Inflationary pressures appear to be largely under control, helped by productivity gains and a positive operating environment for European companies that are finding strong export markets for their goods and services around the globe. Japanese economic growth continues to make progress, and the country has become a more attractive market compared to recent years. China continues its rise as a world economic power, and its stock market 2 Letter has experienced the wide market swings that often accompany rapid growth. While the outlook generally appears favorable for investors, sudden swings in the markets should be expected. Just as staying diversified and staying invested are important investment principles, it is also important to pay attention to asset allocation. As always, we encourage shareowners to work closely with their financial advisor to find the appropriate mix of investments in stocks, bonds and money market assets so that it is aligned to your particular risk tolerance and investment objective.

Q: How did the US stock market perform during the past six months? A: Helped by a continued backdrop of moderate economic growth, stable short-term interest rates, and rising acquisition activity by private equity firms, US equities delivered a solid gain during the semi-annual period. The market marched steadily higher from the beginning of the period through the final week of February, then paused briefly on concerns that weakness in the sub-prime mortgage sector would spread to the rest of the economy. The downturn proved short-lived, however, and stocks quickly recovered to finish March not far off from previous highs. The result was a six-month total return of 9.34% for the Fund's benchmark, the Russell 1000 Value Index. Q: Please discuss the Fund's performance versus its benchmark and Lipper peers. A: During the six months ended March 31, 2007, the Class A shares of Pioneer Value Fund returned 8.25% at net asset value, which was below the return of the benchmark. In comparison, the average return of the 515 funds in its Lipper peer group, Large-Cap Value Funds, was 7.91%. To review, our approach is to use fundamental research to build a portfolio of stocks whose prices do not fully reflect what we believe is the intrinsic value of the underlying companies. The portfolio tends to be focused in about 40-60 stocks in which we hold the highest level of conviction. We believe our focus on purchasing shares in undervalued companies will stand the Fund in good stead over time.

Current performance may be lower or higher than the performance data quoted. 4 Pioneer Value Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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 holdings helped performance? A: Our stock picks generated the largest degree of outperformance in the health-care and consumer-staples sectors. In the former, the leading contributor was the pharmaceutical company Schering-Plough. Our initial purchase was based on our belief that Schering was a turnaround candidate, and that view has since been borne out as the company has reported rising sales, better profit margins, and an improved pipeline of new drugs. Its shares climbed from $22.09 to $25.51 during the semiannual period, and that had a positive impact on Fund performance since it was our largest portfolio holding at almost 5% of assets. In consumer staples, the leading contributor was Altria, which encompasses Phillip Morris USA, Phillip Morris International, and, until recently, Kraft Foods. We believed the company was valued for less than the sum of its parts, and that gap has begun to close after Altria spun out its entire position in Kraft. We continue to hold both entities in the Fund. Outside of health care and consumer staples, we also benefited from the strong performance of Nikko Cordial, Unum Corp. and Freeport-McMoRan Copper and Gold. Nikko Cordial is a Japanese brokerage firm whose shares fell sharply in early 2006 on worries that it would be de-listed from the Tokyo Stock Exchange. Since a number of large Japanese institutions can invest in only listed companies, the prospect of a de-listing caused the stock to be hit by a wave of forced selling. Seeing this short-term anomaly as an opportunity to buy shares in a company with what we believe to be strong long-term fundamentals, we established a position and benefited when the stock subsequently recovered. Unum, meanwhile, is a long-time Fund holding that we bought on the expectation of a turnaround. Our view has been borne out, as the company has been improving its business performance and has elected to securitize some of its underperforming assets and thereby free up capital that it can put to work elsewhere. Unum's shares moved from $19.39 to $23.03 over the past six months. 5 Pioneer Value Fund - -------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 3/31/07 (continued) - -------------------------------------------------------------------------------- Rounding out the list of leading contributors was Freeport-McMoRan, whose purchase of its competitor Phelps Dodge will make it the pre-eminent copper company in the world - an enviable position given that robust demand for the metal has caused its price to rise sharply in recent years. Q: What positions detracted from performance? A: The majority of the Fund's detractors were stocks associated with slumping housing prices and concerns about the ability of homeowners to continue paying their mortgages. Worries that the weakness in the sub-prime market would spread throughout the entire US economy took down the shares of virtually any company with exposure to housing - even those whose fundamentals remained sound. A prime example was Washington Mutual, whose shares plunged in late February / early March even though the company has only a moderate exposure to the sub-prime area. We believe this sell-off was largely unwarranted given the company's solid balance sheet and a safe dividend north of 5%, and we added to the Fund's position. Freddie Mac was another holding that was hurt by the broader environment, and here too we took the opportunity to pick up shares at what we believe to be an attractive price. Wachovia Bank, Home Depot, and Wal-Mart were other Fund holdings that underperformed as a result of the housing issue, but we believe all three remain stable and undervalued. We also initiated a position in First Marblehead - which securitizes and services student loans and therefore was hit by concerns about rising defaults - once the stock price fell to our valuation target. Also detracting from performance was the Fund's position in the insurance company Allstate. The stock did not perform particularly poorly, but the fact that it is a large holding in the portfolio meant that its modest decline had a meaningful impact on performance. We have kept the Fund's position on the basis of, in our opinion, the stock's attractive valuation, robust fundamentals and effective management team. Q: Do you have any closing thoughts for investors? A: The events of late February and early March served as a reminder that risk is still very much part of the investment equation. Stocks have performed very well in recent years, but the most recent downturn shows that volatility can strike at any time. While this is 6 Pioneer Value Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- a negative for short-term investors, we look at market fluctuations as an outstanding opportunity to purchase shares in companies that we believe are attractively valued, as we did most recently with Washington Mutual, Freddie Mac and First Marblehead. The stock market will always be volatile in the short-term, but we believed that those who remain focused on owning shares in companies trading for less than their intrinsic value will be rewarded over time. 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.

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 Value Fund Based on actual returns from October 1, 2006 through March 31, 2007.** Share Class A B C Investor R Y - ----------------------------------------------------------------------------------------------- Beginning Account $1,000.00 $1,000.00 $1,000.00 $1,000.00 $1,000.00 $1,000.00 Value On 10/1/06 Ending Account $1,082.50 $1,076.70 $1,077.10 $1,063.60 $1,086.20 $1,084.80 Value On 3/31/07** Expenses Paid $ 4.88 $ 10.77 $ 10.51 $ 1.40 $ 9.25 $ 2.81 During Period* * Expenses are equal to the Fund's annualized expense ratio of 0.94%, 2.08%, 2.03%, 0.70%, 2.61% and 0.54% for Class A, Class B, Class C, Investor Class, Class R and Class Y shares, respectively, multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period) (71/365 for Investor Class) (124/365 for Class R). ** 12/10/06 for Investor Class shares and 2/1/07 for Class R shares. 14 Pioneer Value Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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.

Organization and Significant Accounting Policies Pioneer Value Fund (the Fund), is a Delaware statutory trust registered under the Investment Company Act of 1940 as a diversified, open-end management investment company. The investment objective of the Fund is reasonable income and growth of capital. The Trustees have authorized the issuance of four classes of shares of the Fund. The Fund currently offers four classes of shares designated as Class A, Class B, Class C, and Class Y shares. As planned, Investor Class shares converted to Class A shares on December 10, 2006. Class R shares were first publicly offered on April 1, 2003 and ceased operations on February 1, 2007. Class Y shares were first publicly offered on August 11, 2004. 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 each class of shares can bear different transfer agent and distribution fees and have exclusive voting rights with respect to the distribution plans that have been adopted by Class A, Class B, and Class C, respectively. 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 investment risks is contained in the Fund's prospectus(es). 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 preparation of its financial statements, which are consistent with those policies generally accepted in the investment company industry: 32 Pioneer Value Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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 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 March 31, 2007 there were no securities fair valued. Temporary cash investments are valued at either amortized cost or 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. B. Foreign Currency Translation The books and records of the Fund are maintained in U.S. dollars. Amounts denominated in foreign currencies are translated into U.S. dollars using current exchange rates. Net realized gains and losses on foreign currency transactions, if any, represent, among other things, the net realized gains and losses on foreign currency contracts, disposition of foreign 33 Pioneer Value Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 3/31/07 (unaudited) (continued) - -------------------------------------------------------------------------------- currencies and the difference between the amount of income accrued and the U.S. dollars actually received. Further, the effects of changes in foreign currency exchange rates on investments are not segregated in the statement of operations from the effects of changes in market price of those securities but are included with the net realized and unrealized gain or loss on investments. C. 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 realized gain on investment transactions, or from paid-in capital, depending on the type of book/tax differences that may exist. At September 30, 2006, the Fund reclassified $2,233,322 to decrease undistributed net investment income and $2,233,322 to increase accumulated net realized gain on investments and foreign currency transactions to reflect permanent book/tax differences. This reclassification has no impact on the net asset value of the Fund and is designed to present the Fund's capital accounts on a tax basis. The tax character of current year distributions will be determined at the end of the fiscal year. The tax character of distributions paid during the year ended September 30, 2006 was as follows: - -------------------------------------------------------------------------------- 2006 - -------------------------------------------------------------------------------- Distributions paid from: Ordinary income $ 61,272,548 Long-term capital gain 28,611,943 Return of capital - ------------ Total $ 89,884,491 ============ - -------------------------------------------------------------------------------- 34 Pioneer Value Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- The following shows the components of distributable earnings on a federal income tax basis at September 30, 2006. - -------------------------------------------------------------------------------- 2006 - -------------------------------------------------------------------------------- Undistributed ordinary income $ 23,985,777 Undistributed long-term gain 530,713,551 Unrealized appreciation 516,977,867 -------------- Total $1,071,677,195 ============== - -------------------------------------------------------------------------------- The difference between book-basis and tax-basis unrealized appre ciation is attributable to the tax deferral of losses on wash sales. D. Forward Foreign Currency Contracts The Fund enters into forward foreign currency contracts (contracts) for the purchase or sale of a specific foreign currency at a fixed price on a future date as a hedge or cross-hedge against either specific investment transactions (settlement hedges) or portfolio positions (portfolio hedges). All contracts are marked to market daily at the applicable exchange rates, and any resulting unrealized gains or losses are recorded in the Fund's financial statements. The Fund records realized gains and losses at the time a portfolio hedge is offset by entry into a closing transaction or extinguished by delivery of the currency. Risks may arise upon entering into these contracts from the potential inability of counterparties to meet the terms of the contract and from unanticipated movements in the value of foreign currencies relative to the U.S. dollar. As of March 31, 2007 the Fund had no outstanding settlement or portfolio hedges. E. Fund Shares The Fund records sales and repurchases of its shares as of trade date. Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the Fund and a wholly owned indirect subsidiary of UniCredito Italiano S.p.A. (UniCredito Italiano), earned $92,133 in underwriting commissions on the sale of Class A shares during the six months ended March 31, 2007. 35 Pioneer Value Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 3/31/07 (unaudited) (continued) - -------------------------------------------------------------------------------- F. Class Allocations Distribution fees are calculated based on the average daily net asset value attributable to Class A, Class B, and Class C shares of the Fund, respectively (see Note 4). Class Y shares are not subject to a distribution plan. Shareowners of each class share all expenses and fees paid to the transfer agent, Pioneer Investment Management Shareholder Services, Inc. (PIMSS), for its 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 the 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, and in the same amount, except that Class A, Class B, Class C and Class Y shares can bear different transfer agent and distribution fees. G. 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. H. Security 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 in the fair value of the loaned securities that 36 Pioneer Value Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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 various Time Deposits, which are sponsored by Brown Brothers Harriman & Co., the Fund's custodian. I. Option Writing When the Fund writes an option, an amount equal to the premium received by the Fund is recorded as a liability and is subsequently adjusted to the current fair value of the option written. Premiums received from writing options that expire unexercised are treated by the Fund on the expiration date as realized gains from investments. The difference between the premium and the amount paid on effecting a closing purchase transaction, including brokerage commissions, is also treated as a realized gain, or, if the premium is less than the amount paid for the closing purchase transaction, as a realized loss. If a call option is exercised, the premium is added to the proceeds from the sale of the underlying security currency in determining whether the Fund has realized a gain or loss. The Fund as writer of an option bears the market risk of an unfavorable change in the price of the security underlying the written option. Transactions in written options for the six months ended March 31, 2007 are summarized as follows: - -------------------------------------------------------------------------------- Number of Premiums Contracts Received - -------------------------------------------------------------------------------- Options outstanding at beginning of year - $ - Options opened 47,437 7,215,998 Options exercised (13,337) (3,211,842) Options closed (20,000) (2,311,009) Options expired (3,663) (89,979) ------- ---------- Options outstanding at end of year 10,437 $1,603,168 ======= ========== - -------------------------------------------------------------------------------- 37 Pioneer Value Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 3/31/07 (unaudited) (continued) - -------------------------------------------------------------------------------- 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 0.60% of the Fund's average daily net assets up to $5 billion, 0.575% on the next $5 billion and 0.55% on the excess over $10 billion. The basic fee is subject to a performance adjustment (limited to a maximum of -0.10% applied to average assets during the measurement period) based on the Fund's investment performance as compared with the Russell 1000[RegTM] Value Index over a rolling 36-month period. In addition, the fee is further limited to a maximum annualized rate adjustment of -0.10% (a "ceiling" and a "floor") applied to average assets during the current month. Effective August 1, 2004, PIM commenced a voluntary waiver of the minimum fee provision (the "floor"). For the six months ended March 31, 2007, the aggregate performance adjustment resulted in a decrease to the basic fee of $2,067,660. For the six months ended March 31, 2007, the net management fee was equivalent to 0.51% of average daily net assets. 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 March 31, 2007, $111,892 was payable to PIM related to management fees, administration costs and certain other 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 is $741,180 in transfer agent fees payable to PIMSS at March 31, 2007. 4. Distribution and Service Plans The Fund adopted a Plan of Distribution with respect to Class A, Class B, and Class C shares in accordance with Rule 12b-1 under 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 38 Pioneer Value Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- attributable to each class of shares. The fee consists of a 0.25% service fee and a 0.75% distribution fee paid as compensation for personal services and/or account maintenance services or distribution services with regard to Class B and Class C shares. Included in due to affiliates is $54,007 in distribution fees payable to PFD at March 31, 2007. In addition, redemptions of each class of shares (except Class Y shares) may be subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may be imposed on redemptions of certain net asset value purchases of Class A shares within 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 are subject to a CDSC of 1.00%. Proceeds from the CDSCs are paid to PFD. For the six months ended March 31, 2007, CDSCs in the amount of $30,234 were paid to PFD. 5. Commission Recapture and Expense Offset Arrangements Effective July 15, 2005, the Fund has entered into commission recapture arrangements with brokers with whom PIM places trades on behalf of the Fund where they provide services to the Fund in addition to trade execution. These services included payments of certain expenses on behalf of the Fund. For the six months ended March 31, 2007, expenses were reduced by $15,000 under this agreement. In addition, 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 March 31, 2007, the Fund's expenses were reduced by $126,326 under such arrangements. 6. Line of Credit The Fund, along with certain others 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 39 Pioneer Value Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 3/31/07 (unaudited) (continued) - -------------------------------------------------------------------------------- among such Funds based on their respective borrowing limits. For the six months ended March 31, 2007, the Fund had no borrowings under this agreement. 7. Merger Information On September 22, 2005, beneficial owners of AmSouth Value Fund approved a proposed Agreement and Plan of Reorganization that provided for the merger listed below. This tax-free reorganization was accomplished on September 23, 2005, by exchanging all of AmSouth Value Fund's net assets for Value Fund's shares, based on Value Fund's Class A, Class B, Class C, Investor Class, Class R and Class Y shares' ending net asset value, respectively.

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 29, 2007. 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. 42 Pioneer Value Fund - -------------------------------------------------------------------------------- FACTORS CONSIDERED BY THE INDEPENDENT TRUSTEES IN APPROVING THE MANAGEMENT CONTRACT - -------------------------------------------------------------------------------- The Investment Company Act of 1940 requires that both the Board of Trustees and a majority of the Independent Trustees (collectively "the Trustees"), voting separately, annually approve the Fund's management contract (the "Management Contract"). The Trustees have determined that the terms of the Management Contract are fair and reasonable and that renewal of the contract: (i) will enable the Fund to receive quality investment advisory services at a fee deemed reasonable; and (ii) is in the best interests of the Fund and its shareowners. In making such determinations, the Independent Trustees relied upon the assistance of counsel to the Independent Trustees and counsel to the Fund. Throughout the year, the Independent Trustees regularly met in executive session, separately from the Interested Trustees of the Fund and any officer of Pioneer Investment Management, Inc., the Fund's adviser (the "Investment Adviser"), or its affiliates. While the Trustees, including the Interested Trustees, act on all major matters relating to the Fund, a significant portion of the activities of the Board of Trustees (including certain of those described herein) is conducted through committees, the members of which are comprised exclusively of Independent Trustees. Such committee meetings are attended by officers of the Fund and/or officers of the Investment Adviser to the extent requested by the members of the committee. In evaluating the Management Contract, the Trustees conducted a review that was specifically focused upon the renewal of the Management Contract, and also relied upon their knowledge, resulting from their meetings throughout the year, of the Investment Adviser, its services and the Fund. Both in meetings specifically dedicated to renewal of the Management Contract and at other meetings during the course of the year, the Trustees, including the Independent Trustees, received materials relating to the Investment Adviser's investment and management services under the Management Contract. These materials included information on (i) the investment performance of the Fund, a peer group of funds as classified by Morningstar, Inc., an independent evaluation service ("Morningstar") and an index considered appropriate by the Independent Trustees for this purpose, (ii) sales and redemption activity in respect of the Fund, (iii) the general investment outlook in the markets in which the Fund invests, (iv) arrangements in respect of the distribution of the Fund's shares, (v) the procedures employed to determine the value of each of the Fund's assets, (vi) the Investment Adviser's management of the relationships with the Fund's unaffiliated service providers, (vii) the 43 Pioneer Value Fund - -------------------------------------------------------------------------------- FACTORS CONSIDERED BY THE INDEPENDENT TRUSTEES IN APPROVING THE MANAGEMENT CONTRACT (continued) - -------------------------------------------------------------------------------- record of compliance with the Fund's investment policies and restrictions and with the Fund's Code of Ethics and the structure and responsibilities of the Investment Adviser's compliance department and (viii) the nature, cost and character of non-investment management services provided by the Investment Adviser and its affiliates. Specifically in connection with the Independent Trustees' review of the Management Contract, the Independent Trustees requested, and the Investment Adviser provided, additional information in order to evaluate the quality of the Investment Adviser's services and the reasonableness of the fee under the Management Contract. Among other items, this information included data or analyses of (1) investment performance for one, three, five and ten year periods for the Fund and a peer group of funds selected on the basis of criteria considered appropriate by the Independent Trustees for this purpose, (2) management and other fees incurred by a peer group of funds selected on the basis of criteria considered appropriate by the Independent Trustees for this purpose, (3) the advisory fees of comparable portfolios of other clients of the Investment Adviser, (4) expense ratios for the Fund and a peer group of funds selected on the basis of criteria considered appropriate by the Independent Trustees for this purpose, (5) the overall organization of the Investment Adviser, (6) the Investment Adviser's financial results and condition, including its and certain of its affiliates' profitability in providing services to the Fund, (7) transfer agency fees and administrative reimbursements paid to the Investment Adviser or affiliates, (8) investment management staffing, and (9) operating expenses paid by the Funds to third parties. The Trustees also reviewed information regarding the potential for each of the Fund and the Investment Adviser to benefit from further economies of scale in the management of the Fund in light of reasonable growth expectations for the Fund and certain of the Fund's expenses that are incurred on a basis other than as a percentage of net assets. The following summarizes factors considered by the Trustees in connection with reviewing the information described above and their renewal of the Fund's Management Contract. The Trustees did not identify any single factor as all-important or controlling, and the summary does not detail all the matters that were considered. A. Ancillary Benefits to Shareowners. The Trustees considered the benefits to shareowners of investing in a Fund that is part of a large number of investment companies offering a variety of 44 Pioneer Value Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- investment disciplines and providing for a large variety of Fund and shareowner services. B. Compliance and Investment Performance. The Trustees determined that the Investment Adviser had policies and systems reasonably designed to achieve compliance with the Fund's investment objective and regulatory requirements. The Trustees also reviewed the Fund's absolute investment performance based upon total return, as well as the Fund's performance relative to the performance of both a peer group and an index considered appropriate by the Independent Trustees for this purpose. The Fund's performance, based upon total return, was in the third quintile of its Morningstar category peer group for the 12 months ended June 30, 2006, the third quintile of the peer group for the three years ended June 30, 2006, the third quintile for the five years ended June 30, 2006, and the fourth quintile for the ten years ended June 30, 2006. (In all quintile rankings referred to throughout this discussion first quintile is most favorable to the Fund's shareowners. Thus, highest relative performance would be first quintile and lowest relative expenses also would be first quintile.) The Trustees, focusing on three-year total returns, concluded that the performance of the Fund was satisfactory. C. The Investment Adviser's Personnel and Methods. The Trustees reviewed the background of members of the team responsible for the daily management of the Fund and the Fund's investment objective and discipline. The Independent Trustees also have had discussions with senior management of the Investment Adviser responsible for investment operations and the senior management of the Investment Adviser's equities group. Among other things, the Trustees considered the size, education and experience of the Investment Adviser's investment staff and their use of technology and emphasis on analytics in view of the risk profile of securities in which the Fund invests. The Trustees concluded that the Investment Adviser had the quality and depth of personnel and the well-developed methods essential to perform its duties under the Management Contract. D. Nature and Quality of Other Services. The Trustees considered the nature, quality and extent of other services provided to shareowners of the Fund, including administrative and shareowner services performed by the Investment Adviser under the Management Contract. The Trustees also considered the reasonableness of the 45 Pioneer Value Fund - -------------------------------------------------------------------------------- FACTORS CONSIDERED BY THE INDEPENDENT TRUSTEES IN APPROVING THE MANAGEMENT CONTRACT (continued) - -------------------------------------------------------------------------------- arrangements for reimbursement of the Investment Adviser's out-of-pocket costs and expenses, including overhead, for certain administrative services that the Investment Adviser is not required to provide under the Management Contract. The Trustees also considered the nature and extent of the other services provided by the Investment Adviser or its affiliates under other contracts, as well as the Investment Adviser's supervision of third party service providers. Based on these considerations, the Trustees concluded that the nature, quality and extent of such services are satisfactory and reliable and serve the shareowners of the Fund well. E. Management Fee and Expenses. The Trustees considered the Investment Adviser's fee under the Management Contract relative to the management fees charged by its Morningstar category peer group. The Fund's management fee for the 12 months ended June 30, 2006 was in the first quintile relative to the management fees paid by the other funds in that peer group for the comparable period. The Trustees also considered the Fund's expense ratio for the 12 months ended June 30, 2006 and expense ratios for the comparable period of the peer group of funds selected on the basis of criteria considered appropriate by the Independent Trustees for this purpose using data provided by Strategic Insight Mutual Fund Research and Consulting, LLC, an independent third party. The Trustees found the Fund's expense ratio for the 12 months ended June 30, 2006 to be in the second quintile, according to data for the applicable peer group for the most recent fiscal year. F. Profitability. The Trustees considered the level of the Investment Adviser's profits with respect to the management of the Pioneer Funds, including a review of the Investment Adviser's methodology in allocating certain of its costs to the management of each Fund, as well as the financial results realized by the Investment Adviser in connection with the operation of the Fund. They further considered the profits realized by the Investment Adviser and its affiliates from non-fund businesses that may benefit from or be related to the Fund's business. The Trustees considered the Investment Adviser's profit margins in comparison with the limited industry data available. The Trustees concluded that the Investment Adviser's profits from management of the Pioneer Funds, including the financial results derived from the Fund, bear a reasonable relationship to the services rendered and are fair for the management of the Fund. 46 Pioneer Value Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- G. Economies of Scale. The Trustees considered the economies of scale with respect to the management of the Fund, whether the Fund had appropriately benefited from any economies of scale, and whether there was potential for realization of any further economies of scale. The Trustees concluded that, because of break points at future asset levels, any perceived or potential economies of scale would be shared between Fund's shareowners and the Investment Adviser in a reasonable manner as the Fund grows in size. H. Other Benefits to the Investment Adviser. The Trustees also considered the character and amount of fees paid by the Fund, other than under the Management Contract, for services provided by the Investment Adviser and affiliates, including fees for services such as shareowner services. The Trustees also considered the receipt of sales loads and payments under Rule 12b-1 plans in respect of the Pioneer Funds (including the Fund), and benefits to the Investment Adviser from the use of "soft" commission dollars to pay for research services. The Trustees further considered the revenues and profitability of the Investment Adviser's businesses other than the fund business, including the Investment Adviser's institutional investment advisory business. The Trustees considered the intangible benefits that accrue to the Investment Adviser and its affiliates by virtue of its relationship with the Fund and the Pioneer Funds as a group. The Trustees concluded that all these types of benefits accruing to the Investment Adviser were reasonable in the context of the overall relationship between the Investment Adviser and the Fund. Conclusion. In light of the Investment Adviser's overall performance, the Trustees considered it appropriate to continue to retain the management services of the Investment Adviser. Based on their review of the overall nature and quality of services provided by the Investment Adviser and the fees charged by other funds in the Fund's relevant peer group, and taking into account all material factors deemed relevant by the Trustees as well as the advice of independent counsel, the Trustees concluded that the Management Contract with the Fund, including the fee payable thereunder, was fair and reasonable and that its renewal was in the best interests of the Fund and its shareholders. Accordingly, the Trustees voted to approve the continuation of the Management Contract for another year. 47 Pioneer Value Fund - -------------------------------------------------------------------------------- TRUSTEES, OFFICERS AND SERVICE PROVIDERS - -------------------------------------------------------------------------------- Trustees Officers 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. 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.
