Dear Shareowner,
- --------------------------------------------------------------------------------
Staying diversified and keeping your portfolio invested in the markets are two
general investment principles that have served investors well over time. They
are particularly useful guides to keep in mind today, at a time when markets
around the globe are being buffeted by problems in the financial and real
estate industries and by concerns about a slowing economy.

After an extended period of steady growth with sustained low unemployment and
low inflation, the U.S. economy ran into difficulty as 2007 drew to a close.
Problems in the financial system tied to poor practices in the mortgage
financing industry and the end of home price appreciation have forced investors
and bankers to mark down the value of assets on their balance sheets. A
late-summer credit crunch forced central banks in the U.S. and Europe to assume
the role of "lender of last resort" to keep credit markets functioning as a
number of hedge funds faced margin calls and, in March, broker Bear Stearns
failed. As the repercussions of the credit crunch and falling home prices were
felt in the real economy, unemployment rose and consumer confidence fell.
Inflation concerns have moved temporarily to the back burner for the U.S.
Federal Reserve, which lowered interest rates, first gradually, then more
rapidly, as concern grew that falling home prices and disruptions in financial
markets posed a significant threat to economic growth.

Markets have reacted poorly to these developments, with fixed-income credit
spreads (the difference in rates between corporate and U.S. government bonds)
widening dramatically and stock markets declining, wiping out much of the
positive returns markets had delivered in the preceding year. For the 6 months
ending March 31, 2008, the Dow Jones Industrial Average fell 11%, the Standard
& Poor's 500 Index declined 12% and the NASDAQ Composite Index fell 16%. The
MSCI EAFE Developed Market Index of international stock markets fell 9%, and
the MSCI Emerging Markets Index fell 8% over the six-month period. The U.S.
investment-grade bond market, as measured by the Lehman Brothers Aggregate Bond
Index, was a solid performer over the 6 months ending March 31, 2008, rising
5%. The U.S. high-yield bond market, as measured by the Merrill Lynch High
Yield Bond Master II Index, fell approximately 4% over the six-month period, as
its higher coupon yields could not offset a fall in bond prices triggered by
widening credit spreads.

Letter

Looking forward, a growing number of economists are concerned about a
recession. As always, though, emotions can get ahead of reality. The U.S.
economy grew in the fourth quarter of 2007 and may have grown in the first
quarter of 2008. Higher mortgage defaults, a spreading of weakness to other
consumer sectors or to employment, and the possibility of a worsening of the
liquidity/credit crunch represent risks to the economy. Conversely, substantial
fiscal and monetary stimulus programs have been put in place, economic growth
in the rest of the world remains relatively positive, and a weak U.S. dollar
has significantly benefited U.S. companies competing in the global marketplace.
While falling risk tolerances and deleveraging may continue to depress asset
prices in the short term, equity and corporate bond valuations look reasonable
unless the U.S. economy falls into a severe recession.

Sudden swings in the markets are always to be expected. The history of the
stock market demonstrates that sharp market downturns are frequently followed
by strong recoveries, but they are also difficult to time. Just as staying
diversified and invested are important investment principles, it is also
important to pay attention to asset allocation. As always, we encourage you to
work closely with your financial advisor to find the mix of stocks, bonds and
money market assets that is best aligned to your particular risk tolerance and
investment objective.

Respectfully,

/s/ Daniel K. Kingsbury

PORTFOLIO MANAGEMENT DISCUSSION 3/31/08
- --------------------------------------------------------------------------------

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 six-month period ended March 31, 2008.

Q:   How did the U.S. stock market perform during the six-months ended March 31,
     2008?

A:   The most recent six-month period was a difficult one for the U.S. stock
     market. The effects of the subprime mortgage crisis became more widespread
     as the reporting period progressed, with the freeze-up of the credit
     markets growing increasingly severe even in the face of aggressive interest
     rate cuts by the U.S. Federal Reserve Board (the Fed). This, in turn, led
     to deepening concerns about banks' balance sheets and extremely poor
     performance for financial stocks. By the first quarter of 2008, it was
     becoming increasingly apparent that the issues in the financials sector
     were spreading into the broader U.S. economy, dampening growth and
     increasing the likelihood of a recession. The crisis appeared to reach a
     crescendo in mid-March, when the collapse of Bear Stearns prompted a
     government-backed bailout of the 85-year old brokerage firm. Nevertheless,
     as we discuss in further detail below, we believe this challenging market
     backdrop has created a much more fertile environment for finding the types
     of value stocks in which we seek to invest.

Q:   Please discuss the Fund's performance versus its benchmark and Lipper peers
     over the past six months.

A:   During the six months ended March 31, 2008, the Class A shares of Pioneer
     Value Fund returned -21.55% at net asset value, trailing its benchmark, the
     Russell 1000 Value Index, which returned -14.01% over the same period. The
     Fund also underperformed the -13.74% average return over the same period of
     the 553 funds in its Lipper peer group, Large-Cap Value Funds.

     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:   Why did the Fund underperform during the period?

A:   The vast majority of the Fund's underperformance was the result of our
     investments in the health care sector. The Fund was positioned in a fairly
     defensive manner via its good-sized weighting in pharmaceutical stocks,
     which typically perform well amid times of distress for the overall stock
     market and/or the broader economy. During the most recent six-month period,
     however, the Fund's holdings in the sector generated unusually poor
     performance. The most significant laggard was Schering-Plough, which fell
     over 25% over the six months ending March 31. Schering-Plough's decline was
     due largely to the release of a study that questioned the effectiveness of
     the company's leading source of revenue, the cholesterol drug Vytorin. The
     resulting decline in Schering's stock price made a substantial dent in the
     Fund's performance, accounting for about 300 basis points (or 3%) of its
     754 (7.54%) basis-point shortfall relative to the benchmark. We continue to
     hold Schering in the portfolio, as we question the study's approach and
     believe the market reaction to the study was overblown. Still, we expect
     volatility to continue as questions will likely continue to surround the
     stock in the short term.

     The Vytorin news also led to a decline in the Fund's position in Merck,
     which has a stake in the drug via a joint venture with Schering-Plough.
     Merck's stock fell less than Schering's on the news (about a 15% decline),
     primarily because the company's overall revenues are less dependent on
     Vytorin sales than Schering's. Still, Merck's poor performance lopped about
     50 basis points off the Fund's performance during the semiannual reporting
     period. Also in pharmaceuticals, the Fund's position in Bristol-Myers
     accounted for another 80 basis points of underperformance. We nevertheless
     continue to find the stock attractive based on its inexpensive valuation,
     sound fundamentals, and a dividend yield near 6%.

                                                                               5

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

     Outside of the health care sector, our position in First Marblehead stood
     out as an underperformer. The company's main business involves taking
     student loans issued by larger companies, packaging them, and securitizing
     them ("securitization" is the process of converting assets, most commonly
     accounts receivables, into marketable securities). However, the freezing up
     of the credit markets has meant that First Marblehead has been unable to
     sell the securitized loans and has been forced to hold onto them until
     conditions improve. Thus, the company was forced to go to Goldman Sachs for
     financing in order to maintain its viability. The result was a large
     decline in First Marblehead's stock price from $37.93 to $7.46 during the
     semiannual reporting period ended March 31, 2008. We continue to hold the
     stock in the Fund, but as a much smaller percentage of our total assets
     following its poor market performance.

Q:   What positions were helpful to Fund performance during the period?

A:   Outside of the handful of companies mentioned above, our stock selection
     was solid. The Fund outperformed the benchmark in six of the ten major
     industry sectors, and held a number of stocks that performed well despite
     the down market. A key source of strength was the energy sector, where
     companies such as Apache and Devon Energy benefited from the rising prices
     of oil and natural gas. Outside of energy, Altria, Gap Stores and Wal-Mart
     stood out as winners. The Fund also benefited from not owning a handful of
     poor-performing stocks, most notably Citigroup and Sprint, both of which
     declined dramatically during the past half-year. Unfortunately, the
     positive elements of the Fund's positioning were not enough to offset the
     impact of First Marblehead and poor-performing holdings in the
     pharmaceutical sector.

Q:   Have you added any new holdings in the wake of the market's downturn?

A:   Yes. We have indeed taken advantage of the market's volatility to add new
     positions to the Fund. During the past several years, it has been difficult
     to find the type of outstanding value opportunities that can be created
     when stress in the broader market drives stock prices down to unreasonably
     low valuations. Throughout the past six or seven months, however, the
     difficulties in the mortgage and credit markets have made the opportunities
     more plentiful.

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

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

     Given the nature of the issues weighing on the market, it should come as no
     surprise that we have found the majority of our value plays in the
     financial sector. We have added a number of smaller positions in order to
     ensure appropriate portfolio diversification at a time of elevated risk. In
     the process, we have increased the Fund's weighting in financials from
     about 15% of assets six months ago to 28% at the close of the period. While
     we do not expect a "V-shaped" recovery in financials, we believe that the
     bulk of the bad news for the sector is now largely in the rearview mirror.
     That has created opportunities to buy companies at or below book value for
     holding periods of what we expect will be about three or four years.

     An example of a new holding in the financial sector is the credit card
     issuer Capital One, a financially-sound company that was trading below book
     value at the time of our purchase. We stress-tested the company's earnings
     to reflect a year's worth of credit losses roughly equivalent to that which
     occurred during the last recession. Even under that worst-case scenario, we
     see the potential for about $8 per share of earnings in 2009, which makes
     the Fund's average share cost in the low $40s appear to be an excellent
     entry point. Another example of a recent purchase is Lehman Brothers, which
     in early 2008 traded down to its book value despite its strong balance
     sheet and diversified funding base. We are enthusiastic on the outlook for
     the stock based on its potential earnings power in 2009 and 2010, by which
     time we expect market conditions will have normalized.

     Not all of the recent additions were financial stocks. We also used the
     market downturn to add to stocks in another sector pressured by recession
     fears - consumer cyclicals - largely by adding to the Fund's weighting in
     stocks such as Gap Stores and Home Depot. The result was an increase of
     about one percentage point in the Fund's weighting in the consumer
     discretionary sector.

Q:   Do you have any closing thoughts for investors?

A:   Although the Fund underperformed during the most recent half-year, we
     believe our value-oriented, research-based discipline will bear fruit in
     the long term. In addition, we are excited that market volatility has
     presented us with an opportunity to buy discounted shares in the types of
     companies mentioned above. While market

                                                                               7

     corrections can be distressing in the short term, they also can prove very
     rewarding for long-term investors like us. We believe our focus on
     purchasing shares of undervalued, higher-quality companies will hold the
     Fund in good stead in the months and years ahead.

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.

Note to Shareowners: Aaron Clark, lead portfolio manager of Pioneer Value Fund,
has resigned from Pioneer Investments effective May 1, 2008. Mr. Clark had been
portfolio manager of the Pioneer Value Fund since May, 2006.

Rod Wright, strategy director of Pioneer's large-and mid-value equity team,
will immediately assume portfolio management responsibilities. Mr. Wright has
been assisting Mr. Clark on these portfolios and thus we expect a smooth
transition. Brad Galko will support Mr. Wright as a portfolio manager of
Pioneer Value Fund. The investment objective for the Fund will remain the same
and Mr. Wright, Mr. Galko and the U.S. value team will continue to be supported
by Pioneer's global equity research team.

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.

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

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

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 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.

COMPARING ONGOING FUND EXPENSES
- --------------------------------------------------------------------------------

As a shareowner in the Fund, you incur two types of costs:

(1)  ongoing costs, including management fees, distribution and/or service
     (12b-1) fees, and other Fund expenses; and

(2)  transaction costs, including sales charges (loads) on purchase payments.

This example is intended to help you understand your ongoing expenses (in
dollars) of investing in the Fund and to compare these costs with the ongoing
costs of investing in other mutual funds. The example is based on an investment
of $1,000 at the beginning of the Fund's latest six-month period and held
throughout the six months.

Using the Tables

Actual Expenses

The first table below provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you paid over the period as
follows:

1.   Divide your account value by $1,000
     Example: an $8,600 account value [divided by] $1,000 = 8.6

2.   Multiply the result in (1) above by the corresponding share class's number
     in the third row under the heading entitled "Expenses Paid During Period"
     to estimate the expenses you paid on your account during this period.

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 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 January 31, 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. The Fund's prospectuses contain information regarding
the Fund's principal risks. 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:

                                                                              31

NOTES TO FINANCIAL STATEMENTS 3/31/08 (unaudited)                  (continued)
- --------------------------------------------------------------------------------

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 may also 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, 2008, there were no
     securities fair valued. Temporary cash investments are valued at cost which
     approximates market value.

     Dividend income is recorded on the ex-dividend date, except that certain
     dividends from foreign securities where the ex-dividend date may have
     passed are recorded as soon as the Fund becomes aware of the ex-dividend
     data in 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

32


Pioneer Value Fund
- --------------------------------------------------------------------------------

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

     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. Tax
     years prior to 2004 are closed (not subject to examination by tax
     authorities) due to the expiration of statute of limitations; all other tax
     years are open.

     The amounts and characterizations of distributions to shareowners for
     financial reporting purposes are determined in accordance with federal
     income tax rules. Therefore, the sources of the Fund's distributions may be
     shown in the accompanying financial statements as from or in excess of net
     investment income or net realized gain on investment transactions, or as
     from paid-in capital, depending on the type of book/tax differences that
     may exist.

     The tax character of current year distributions paid will be determined at
     the end of the current fiscal year. The tax character of distributions paid
     during the year ended September 30, 2007, was as follows:

     The following shows the components of distributable earnings on a federal
     income tax basis at September 30, 2007:



- --------------------------------------------------------------------------------
                                                                    2007
- --------------------------------------------------------------------------------
                                                            
 Undistributed ordinary income                                  $ 93,166,332
 Undistributed long-term gain                                    205,466,245
 Unrealized appreciation                                         688,736,445
                                                                ------------
   Total                                                        $987,369,022
                                                                ============
- --------------------------------------------------------------------------------


     The difference between book-basis and tax-basis unrealized appreciation 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, 2008, 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 $211,038 in underwriting commissions on the
     sale of Class A shares during the six months ended March 31, 2008.

Pioneer Value Fund
- --------------------------------------------------------------------------------

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

F.   Class Allocations

     Income, common expenses and realized and unrealized gains and losses are
     calculated at the Fund level and allocated daily to each class of shares
     based on the respective percentage of adjusted net assets at the beginning
     of the day.

     Distribution fees are calculated based on the average daily net asset value
     attributable to Class A, Class B, 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 participate in 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).

     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 expense rates.

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

                                                                              35


Pioneer Value Fund
- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 3/31/08 (unaudited)                  (continued)
- --------------------------------------------------------------------------------

     receive interest or payments in lieu of dividends on the securities loaned.
     Gain or loss in the fair value of the loaned securities that may occur
     during the term of the loan will be for the account of the Fund. The loans
     are secured by collateral which is required to be at least 102%, at all
     times, of the fair value of the securities loaned. The amount of the
     collateral is required to 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 Credit Suisse, Inc.

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 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.

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 up to 0.10% (a "ceiling") applied to average
assets during the current month. For the six months ended March 31, 2008, the
aggregate performance adjustment resulted in a decrease to the basic fee of
$1,775,043. For the six months ended March 31, 2008, the net management fee was
equivalent to 0.50% 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. Included in "Due to affiliates" reflected on
the Statement of Assets and Liabilities is $51,789 in management fees,
administrative costs and certain other services payable to PIM at March 31,
2008.

                                                                              37

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" reflected on the Statement of
Assets and Liabilities is $266,853 in transfer agent fees payable to PIMSS at
March 31, 2008.

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. Currently under the Class A Plan, PFD is reimbursed for distribution
expenses in an amount of up to 0.25% of the average daily net assets
attributable to Class A shares. Pursuant to the Class B Plan and the Class C
Plan, the Fund pays PFD 1.00% of the average daily net assets attributable to
each class of shares. 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" reflected on the Statement of Assets and
Liabilities is $56,163 in distribution fees payable to PFD at March 31, 2008.

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,
2008, CDSCs in the amount of $27,777 were paid to PFD.

5.   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,

Pioneer Value Fund
- --------------------------------------------------------------------------------

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

2008, expenses were not reduced 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, 2008, the Fund's expenses were
reduced by $53,878 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
among such Funds based on their respective borrowing limits. For the six months
ended March 31, 2008, the Fund had no borrowings under this agreement.

7.   New Pronouncements

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.

In March 2008, Statement of Financial Accounting Standards No. 161, Disclosures
about Derivative Instruments and Hedging Activities (SFAS 161), was issued and
is effective for fiscal years beginning after November 15, 2008. SFAS 161
requires enhanced disclosures about an entity's derivative and hedging
activities. Management is currently evaluating the impact the adoption of SFAS
161 will have on the Fund's financial statement disclosures.


                                                                              39

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

Pioneer Investment Management, Inc. (PIM) serves as the Fund's investment
adviser pursuant to an investment advisory agreement between PIM and the Fund.
The Trustees of the Fund, as required by law, determine annually whether to
continue the investment advisory agreement for the Fund.

In connection with their most recent consideration of the investment advisory
agreement for the Fund, the Trustees received and reviewed a substantial amount
of information provided by PIM in response to requests of the independent
Trustees and their independent legal counsel. The independent Trustees met on a
number of occasions with PIM and also separately with their independent legal
counsel to evaluate and discuss the information provided to them by PIM. At a
meeting held on November 13, 2007, based on their evaluation of the information
provided by PIM, the Trustees, including the independent Trustees voting
separately, unanimously approved the continuation of the investment advisory
agreement for another year.

In considering the continuation of the investment advisory agreement, the
Trustees considered various factors that they determined were relevant,
including the factors described below. The Trustees did not identify any single
factor as the controlling factor in determining to approve the continuation of
the agreement.

Nature, Extent and Quality of Services
The Trustees considered the nature, extent and quality of the services provided
by PIM to the Fund, taking into account the investment objective and strategy
of the Fund and the information related to the Fund provided to the Trustees at
each quarterly meeting. The Trustees reviewed the terms of the investment
advisory agreement. The Trustees also reviewed PIM's investment approach for
the Fund and its research process. The Trustees considered the resources of PIM
and the personnel of PIM who provide investment management services to the
Fund. They also considered PIM's compliance and legal resources and personnel.

In addition, the Trustees considered the other services that PIM provides to
the Fund under the investment advisory agreement and that, as administrator,
PIM is responsible for the administration of the Fund's business and other
affairs. It was noted that PIM supervises and monitors the performance of the
Fund's service providers and provides the Fund with personnel (including
officers) as are necessary

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

for the Fund's operations. The Trustees considered the fees paid to PIM for the
provision of such services.

Based on these considerations, the Trustees concluded that the nature, extent
and quality of services provided by PIM to the Fund were satisfactory and
consistent with the terms of the investment advisory agreement.

Performance of the Fund
The Trustees considered the performance results of the Fund over various time
periods. They reviewed information comparing the Fund's performance with the
average performance of its peer group of funds as classified by Morningstar,
Inc. (Morningstar), an independent provider of investment company data, and
with the performance of the Fund's benchmark index. The Trustees considered
that the Fund's annualized total return was in the fourth quintile of its
Morningstar category for the one, three and five year periods ended June 30,
2007. (In all quintile rankings referred to throughout this disclosure, first
quintile is most favorable to the Fund's shareowners. Thus, highest relative
performance would be first quintile and lowest relative expenses would also be
first quintile.) The Trustees considered the recent changes in the Fund's
portfolio management team and that performance appeared to be improving and
concluded that the investment performance of the Fund was satisfactory.

Management Fee and Expenses
The Trustees considered information on the fees and expenses of the Fund in
comparison to the management fees of its peer group of funds as classified by
Morningstar and the expense ratios of a peer group of funds selected on the
basis of criteria determined by the independent Trustees for this purpose using
data provided by Strategic Insight Mutual Fund Research and Consulting, LLC
(Strategic Insight), an independent third party.

The Trustees considered that the Fund's management fee for the twelve months
ended June 30, 2007 was in the first quintile relative to the management fees
paid by other funds in its peer group Morningstar category for the comparable
period. The Trustees also considered that the Fund's expense ratio for the
twelve months ended June 30, 2007 was in the first quintile relative to its
Strategic Insight peer group.

                                                                              41

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

The Trustees also reviewed management fees charged by PIM to its other clients
with a similar investment strategy as the Fund. The Trustees noted that in some
instances the fee rates for those clients were lower than the management fees
for the Fund and considered that, under the investment advisory agreement with
the Fund, PIM performs additional services for the Fund that it does not
provide to those other clients, including oversight of the Fund's other service
providers, regulatory compliance and other services.

The Trustees concluded that the management fee payable by the Fund to PIM was
reasonable in relation to the nature and quality of services provided, taking
into account the fees charged by other advisers for managing comparable mutual
funds with similar strategies. The Trustees also concluded that the Fund's
expense ratio was reasonable, taking into account the size of the Fund, the
quality of services provided by PIM and the investment performance of the Fund.

Profitability
The Trustees considered information provided by PIM regarding the profitability
of PIM with respect to the advisory services provided by PIM to the Fund,
including the methodology used by PIM in allocating certain of its costs to the
management of the Fund. The Trustees also considered PIM's profit margin in
connection with the overall operation of the Fund. They further reviewed the
financial results realized by PIM and its affiliates from non-fund businesses.
The Trustees considered PIM's profit margins with respect to the Fund in
comparison to the limited industry data available and noted that the
profitability of any adviser was affected by numerous factors, including its
organizational structure and method for allocating expenses. The Trustees
recognized that PIM should be entitled to earn a reasonable level of profit for
the services provided to the Fund. The Trustees concluded that PIM's
profitability with respect to the management of the Fund was not unreasonable.

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 the breakpoints in the
management fee schedule and the reduced fee rates above certain asset

42

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

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

levels, any perceived or potential economies of scale would be shared between
PIM and the Fund.

Other Benefits
The Trustees considered the other benefits to PIM from its relationship with
the Fund. The Trustees considered that affiliates of PIM serve as the Fund's
transfer agent and distributor. The Trustees considered the receipt by PIM and
its affiliates of sales loads and payments under Rule 12b-1 plans in respect of
the Fund and the other Pioneer funds and the benefits to PIM and its affiliates
from the use of "soft" commission dollars generated by the Fund to pay for
research and brokerage services. The Trustees further considered the intangible
benefits to PIM by virtue of its relationship with the Fund and the other
Pioneer funds. The Trustees concluded that the receipt of these benefits was
reasonable in the context of the overall relationship between PIM and the Fund.

Conclusion
After consideration of the factors described above as well as other factors,
the Trustees, including all of the independent Trustees, concluded that the
terms of the investment advisory agreement between PIM and the Fund, including
the fees payable thereunder, were fair and reasonable and voted to approve the
proposed continuation of the investment advisory agreement for the Fund.

                                                                              43

 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.
