Dear Shareowner,
- --------------------------------------------------------------------------------
Staying diversified and keeping your portfolio invested in the markets are two
general investment principles that have served investors well over time. 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

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.

Respectfully,
/s/ Daniel K. Kingsbury

PORTFOLIO MANAGEMENT DISCUSSION 3/31/07
- --------------------------------------------------------------------------------

In the following discussion, Aaron Clark, lead portfolio manager, reviews recent
market events and describes the factors that affected Pioneer Value Fund's
performance during the semi-annual period ended March 31, 2007.

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.

     Call 1-800-225-6292 or visit www.pioneerinvestments.com for the most recent
     month-end performance results. 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.

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

- --------------------------------------------------------------------------------
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.

The Russell 1000 Value Index measures the performance of large-cap U.S. value
stocks. Index returns assume reinvestment of dividends and, unlike Fund returns,
do not reflect any fees, expenses or sales charges. You cannot invest directly
in an index.

The index defined here pertains to the "Value of $10,000 Investment" charts on
pages 10-13.

                                                                               9

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.

NAV results represent the percent change in net asset value per share. Returns
would have been lower had sales charges been reflected. POP returns reflect
deduction of maximum 5.75% sales charge. All results are historical and assume
the reinvestment of dividends and capital gains. Other share classes are
available for which performance and expenses will differ.

Performance results reflect any applicable expense waivers in effect during the
periods shown. Without such waivers Fund performance would be lower. Waivers may
not be in effect for all funds. Certain fee waivers are contractual through a
specified period. Otherwise, fee waivers can be rescinded at any time. See the
prospectus and financial statements for more information.

The performance data quoted represents past performance, which is no guarantee

shares, when redeemed, may be worth more or less than their original cost.

"If Held" results represent the percent change in net asset value per share.
Returns would have been lower had sales charges been reflected. "If Redeemed"
returns reflect the deduction of applicable contingent deferred sales charge
(CDSC). Effective December 1, 2004, the period during which a CDSC is applied to
withdrawals was shortened to 5 years. The maximum CDSC for Class B shares
continues to be 4%. For more complete information, please see the prospectus for
details.

Note: Shares purchased prior to December 1, 2004 remain subject to the CDSC in
effect at the time you purchased those shares. For performance information for
shares purchased prior to December 1, 2004, please visit

The performance data quoted represents past performance, which is no guarantee

Class C shares held for less than one year are also subject to a 1% contingent
deferred sales charge (CDSC). The performance of Class C shares does not reflect
the 1% front-end sales charge in effect prior to February 1, 2004. If you paid a
1% sales charge, your returns would be lower than those shown above. "If Held"
results represent the percent change in net asset value per share. Returns would

available for which performance and expenses will differ.

Performance results reflect any applicable expense waivers in effect during the

Call 1-800-225-6292 or visit www.pioneerinvestments.com for the most recent
month-end performance results. 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 for periods prior to the inception of Class Y shares reflects the
NAV performance of the Fund's Class A shares. The performance does not reflect
differences in expenses, including the Rule 12b-1 fees applicable to Class A
shares. Since fees for Class A shares are generally higher than those of Class Y
shares, the performance shown for Class Y shares prior to their inception
(8/11/04) would have been higher. Class Y shares are not subject to sales
charges and are available for limited groups of eligible investors, including
institutional investors. All results are historical and assume the reinvestment
of dividends and capital gains. Other share classes are available for which
performance and expenses will differ.

Performance results reflect any applicable expense waivers in effect during the
periods shown. Without such waivers Fund performance would be lower. Waivers may
not be in effect for all funds. Certain fee waivers are contractual through a
specified period. Otherwise, fee waivers can be rescinded at any time. See the
prospectus and financial statements for more information.

The 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.

                                                                              13

COMPARING ONGOING FUND EXPENSES 3/31/07
- --------------------------------------------------------------------------------

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 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. 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.

1.   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:

  Total                                                             $ 89,884,491
                                                                    ============

     The following shows the components of distributable earnings on a federal
     income tax basis at September 30, 2006.

                                                                  ==============
- --------------------------------------------------------------------------------


     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

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:

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

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

8.   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.

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

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

     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.

- --------------------------------------------------------------------------------

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 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.

                 firm, the scope of the Audit
