President's Letter

Dear Shareowner,

Through the first nine months of 2010, the U.S. economy moved forward on a slow
path to recovery. But with the memory of a deep recession still lingering,
businesses and consumers remained cautious about both investing and spending.
While business fundamentals showed signs of improvement, there was still a
reluctance to hire, and high unemployment remains a problem. Wary investors,
concerned about risk, gravitated towards cash and bonds. We remain generally
optimistic about the prospects for economic recovery, although it may occur
more slowly than many would like.

At Pioneer, we have long advocated the benefits of staying diversified and
investing for the long term. This strategy has generally performed well for
many investors. Bond markets certainly rewarded investors in the first nine
months of 2010. While the equity markets barely budged, equities at the end of
September 2010 were inexpensive relative to bonds, compared with historic
levels, and represented potentially good value for long-term investors.

Pioneer has not changed the basic approach to investing that we have used for
more than 80 years. We remain focused on company fundamentals and risk
management. Our investment process is based on careful research into individual
companies, quantitative analysis, and active portfolio management. This
three-pillared process, which we apply to each of our portfolios, is supported
by an integrated team approach and is designed to carefully balance risk and
reward. Our experienced professionals devote themselves to the careful research
needed to identify investment opportunities in markets around the world.

Our advice, as always, is to work closely with a trusted financial advisor to
discuss your goals and work together to develop an investment strategy that
meets your individual needs. There is no single best strategy that works for
every investor.

investing by consulting with your financial advisor or visiting us online at

you for investing with Pioneer.

Portfolio Management Discussion | 9/30/10

In the following discussion, John Peckham, senior vice president and portfolio
manager at Pioneer Investments, and Rod Wright, senior vice president and
portfolio manager at Pioneer Investments, review recent market events and
describe the factors that affected Pioneer Value Fund's performance during the
12 months ended September 30, 2010. Mr. Peckham is responsible for the
day-to-day management of the Fund's portfolio. He is supported by Mr. Wright.

Q  How did the Fund perform over the 12 months ended September 30, 2010?

A  The Fund's Class A shares returned 3.72% at net asset value over the 12
   months ended September 30, 2010, while the Fund's benchmark, the Russell
   1000 Value Index, returned 8.90%. Over the same 12-month period, the
   average return of the 530 mutual funds in Lipper's Large Cap Value mutual
   funds category was 7.05%.

Q  Value stocks generated very solid performance over the 12 months ended
   September 30, 2010, but they underperformed growth stocks over that same
   time period. How would you characterize the investment environment for
   value stocks over the Fund's fiscal year?

A  The main driver of the relative underperformance of value versus growth
   stocks over the past year was the underperformance of the financial
   services sector versus the information technology sector.

   The financial services sector constitutes nearly 30% of the "value world,"
   while the information technology sector accounts for a similar portion of
   the "growth world." Over the 12 months ended September 30, 2010, the market
   experienced a dramatic bifurcation in returns, with the financial services
   component of the Russell 1000 Value Index (large-cap value stocks) losing
   nearly 2%, while the information technology component of the Russell 1000
   Growth Index (large-cap growth stocks) returned just over 12%.

   Multiple factors weighed on the performance of financial stocks over the
   12-month period. From a macroeconomic perspective, the slow economic
   recovery weighed on loan growth, declining interest rates and a flattening
   yield curve hurt lending profitability, and decreased buying and selling of
   securities diminished trading-desk profitability. Numerous regulatory
   factors also weighed on the financials sector, including new rules for
   debit and credit cards, new overdraft rules for checking accounts,
   restrictions on proprietary trading, and new capital requirements. Investor
   concerns about the macro environment and the new regulations were important
   factors in the


4    Pioneer Value Fund | Annual Report | 9/30/10


   poor performance of the financial services sector over the 12 months ended
   September 30, 2010.

   In contrast, the information technology sector enjoyed strong returns, as
   investors focused on the attractive prospects for many technology stocks.
   The growing importance of "cloud computing" drove much of the enthusiasm
   for tech stocks. Cloud computing is an ill-defined term that generally
   includes outsourcing, simplification, and consolidation of technology
   hardware and software. Another factor that drove technology performance was
   the strong merger and acquisition (M&A) environment, as larger, more mature
   tech companies showed a willingness to bid for smaller, faster-growing
   "cloud" players. Finally, the importance of one technology stock, Apple,
   should not be discounted. Apple's large market capitalization and strong
   stock price performance combined to help drive the technology sector higher
   over the past year.

Q  The Fund underperformed its benchmark, the Russell 1000 Value Index, over the
   12-month period ended September 30, 2010. What were the main reasons for
   this?

A  Poor stock selection drove the Fund's underperformance over the past 12
   months ended September 30, 2010. Our decision to underweight the Fund to
   the telecommunication services sector also hurt performance.

   The strong performance of the telecommunication services sector was a
   surprise to us. We did not expect that the wireless segment would perform
   as well as it did, given high levels of market penetration, and we
   underestimated the companies' ability to stem wireline losses and grow
   video subscribers. Of course, investors' quest for yield was another
   important factor in the sector's strong performance.

   Sector allocation, overall, however, was a modest positive for performance,
   driven by the Fund's underweight position in financials for the entire
   year, and our decision to overweight the Fund to the utilities sector in
   the latter part of the year.

   Our decision to underweight the Fund to financials was driven by the
   challenging prospects for many financial services companies. As noted
   previously, the macro and regulatory environment for financials produced
   material headwinds for the sector. Our decision to overweight the Fund to
   utilities was driven by the attractive total return prospects for the
   sector. The combination of reasonable valuations, potential for higher
   earnings, and strong dividends were the key factors in our positive
   assessment of the sector's total return prospects.


                               Pioneer Value Fund | Annual Report | 9/30/10    5


Q  Can you discuss any individual holdings that had the most influence on the
   Fund's performance, either positively or negatively, over the 12 months
   ended September 30, 2010?

A  Biotechnology company Genzyme was the Fund's top performer over the past 12
   months. We purchased the stock after determining that it was materially
   undervalued following a series of drug manufacturing failures. In our view,
   the company's problems were fixable and management was proceeding on a
   sensible course to correct them. Shortly after we added Genzyme to the
   Fund's portfolio, the pharmaceutical company Sanofi-Aventis reached a
   similar conclusion and made an offer to buy Genzyme at a substantial
   premium.

   Gold company Newmont Mining also was a top performer for the Fund, as gold
   prices rallied to new highs on global macroeconomic concerns.

   Utility company Questar performed well over the past 12 months. We added
   the stock to the Fund's portfolio after concluding the company's parts were
   worth more than its whole. The Fund was rewarded this year after the
   company decided to realize value by spinning out its natural gas
   exploration and production business.

   Several Fund holdings in the energy sector were material underperformers
   over the 12 months ended September 30, 2010. The underperformers included
   deepwater driller Transocean and natural gas exploration and production
   company Southwestern Energy.

   Transocean owned the ill-fated Deepwater Horizon oil rig that was at the
   center of this year's massive B.P. oil spill in the Gulf of Mexico. We sold
   the stock from the Fund's portfolio shortly after the spill occurred, but
   not fast enough to avoid damaging Fund returns.

   Southwestern Energy proved a poor investment over the past year, as natural
   gas prices remained weak. We had expected that natural gas prices would
   improve as a growing economy drove higher demand and a reduction in
   drilling diminished supply. Unfortunately, prices continued to fall as the
   economic recovery stalled and natural gas production continued to rise.
   Southwestern still has several attractive attributes, including high growth
   and low costs. None proved sufficient, however, to overcome the drag of low
   natural gas prices.

   In addition to the Fund's struggles in the energy sector, several stocks in
   the financials sector were material underperformers. These included
   regional bank Zions, investment bank Morgan Stanley and discount brokers TD
   Ameritrade and Charles Schwab.

   In the cases of Zions and Morgan Stanley, we overestimated the companies'
   ability to surmount numerous hurdles, including the macro and regulatory


6    Pioneer Value Fund | Annual Report | 9/30/10


   factors we discussed earlier in this interview. In addition, Zions' Nevada,
   Arizona and California loan books failed to recover as fast as we had
   hoped; and Morgan Stanley's trading business failed to keep pace with some
   of its peers, while its real estate portfolio proved a larger drag than we
   had expected.

   Discount brokers TD Ameritrade and Charles Schwab underperformed largely
   due to lower-than-expected interest rates and diminished trading activity.
   In a low-interest-rate environment, the discount brokers subsidized their
   money market mutual funds to guarantee that investors received a positive
   return. Not surprisingly, the subsidies produced a meaningful earnings
   drag. Also, high levels of equity market volatility caused by several
   factors, including the "flash crash" last May, contributed to diminished
   trading activity in the equity markets.

Q  What is your outlook for value investing and for the U.S. economy in general?

A  We remain optimistic regarding the prospects for value investing,
   particularly in light of recent underperformance. In general, we believe
   that equity valuations remain attractive and we believe value stocks are
   particularly attractive, as many combine lower-than-average valuations,
   better-than-average returns on equity, meaningful international exposure,
   and solid dividend yields.

   We expect that the U.S economy will continue to expand at a modest pace,
   but will be hampered by the prospect of higher taxes, lower government
   spending, and continued de-leveraging by consumers. In addition, it is not
   obvious when the housing market will materially improve.

   We also believe the Federal Reserve Board's proposed "easing" actions could
   keep interest rates low and the dollar weak. In that environment, less
   expensive, higher-quality stocks with solid international growth prospects
   and attractive yields could outperform.

Index Definitions
- --------------------------------------------------------------------------------
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" and "Value
of $5,000,000 Investment" charts on pages 11-14.

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

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 shown for periods prior to the inception of Class Y shares on
August 11, 2004 reflects the NAV performance of the Fund's Class A shares. The
performance does not reflect differences in expenses, including 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 would have been higher than the performance shown. Class Y
shares are not subject to sales charges and are available to 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.


14    Pioneer Value Fund | Annual Report | 9/30/10


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.

Notes to Financial Statements | 9/30/10

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 capital growth.

The Fund offers four classes of shares designated as Class A, Class B, Class C,
and Class Y shares. Effective as of the close of business on December 31, 2009,
Class B shares are no longer offered to new or existing shareholders, except
that dividends and/or capital gain distributions may continue to be reinvested
in Class B shares, and shareholders may exchange their Class B shares for Class
B shares of other Pioneer funds, as permitted by existing exchange privileges.
Each class of shares represents an interest in the same portfolio of
investments of the Fund and has identical rights (based on relative net asset
values) to assets and liquidation proceeds. Share classes can bear different
rates of class-specific fees and expenses such as transfer agent and
distribution fees. Differences in class-specific fees and expenses will result
in differences in net investment income and, therefore, the payment of
different dividends from net investment income earned by each class. The
Amended and Restated Declaration of Trust of the Fund gives the Board the
flexibility to specify either per-share voting or dollar-weighted voting when
submitting matters for shareholder approval. Under per-share voting, each share
of a class of the Fund is entitled to one vote. Under dollar-weighted voting, a
shareholder's voting power is determined not by the number of shares owned, but
by the dollar value of the shares on the record date. Each share class has
exclusive voting rights with respect to matters affecting only that class,
including with respect to the distribution plan for that class. There is no
distribution plan for Class Y shares. Class B shares convert to Class A shares
approximately eight years after the date of purchase.

At times, the Fund's investments may represent industries or industry sectors
that are interrelated or have common risks, making the Fund more susceptible to
any economic, political, or regulatory developments or other risks affecting
those industries and sectors. The Fund's prospectus contains unaudited
information regarding the Fund's principal risks. Please refer to that document
when considering the Fund's principal risks.

The Fund's financial statements have been prepared in conformity with U.S.
generally accepted accounting principles that require the management of the
Fund to, among other things, make estimates and assumptions that affect the
reported amounts of assets and liabilities, the disclosure of contingent assets


32    Pioneer Value Fund | Annual Report | 9/30/10


and liabilities at the date of the financial statements, and the reported
amounts of income, expenses and gains and losses on investments during the
reporting year. Actual results could differ from those estimates.

The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements, which are consistent with
those policies generally accepted in the investment company industry:

A. Security Valuation

   Security transactions are recorded as of trade date. The net asset value of
   the Fund is computed once daily, on each day the New York Stock Exchange
   (NYSE) is open, as of the close of regular trading on the NYSE. In computing
   the net asset value, securities that have traded on an exchange are valued at
   the last sale price on the principal exchange where they are traded.
   Securities that have not traded on the date of valuation, or securities for
   which sale prices are not available, generally are valued at the mean between
   the last bid and asked prices. Securities for which market prices and/or
   quotations are not readily available or are considered to be unreliable are
   valued using fair value methods pursuant to procedures adopted by the Board
   of Trustees.

   Trading in foreign securities is substantially completed each day at various
   times prior to the close of the NYSE. The values of such securities used in
   computing the net asset value of the Fund's shares are determined as of such
   times.

   The Fund may use fair value methods if it is determined that a significant
   event has occurred after the close of the exchange or market on which the
   security trades and prior to the determination of the Fund's net asset value.
   Thus, the valuation of the Fund's securities may differ from exchange prices.
   At September 30, 2010, there were no securities that were valued using fair
   value methods. Short-term fixed-income securities with remaining maturities
   of sixty days or less generally are valued at amortized cost. Money market
   mutual funds are valued at net asset value.

   Dividend income is recorded on the ex-dividend date, except that certain
   dividends from foreign securities where the ex-dividend date may have passed
   are recorded as soon as the Fund becomes aware of the ex-dividend data in the
   exercise of reasonable diligence. Interest income is recorded on the accrual
   basis. Dividend and interest income are reported net of unrecoverable foreign
   taxes withheld at the applicable country rates.

   Gains and losses on sales of investments are calculated on the identified
   cost method for both financial reporting and federal income tax purposes.


                              Pioneer Value Fund | Annual Report | 9/30/10    33


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 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 for the prior three fiscal years are subject to examination by tax
   authorities.

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

   At September 30, 2010, The fund had a net capital loss carryforward of
   $722,904,359, of which the following amounts will expire between 2017 and
   2018 if not utilized: $403,358,897 in 2017 and $319,545,462 in 2018.

   The Fund has elected to defer $119,558 in capital losses recognized between
   November 1, 2009 and September 30, 2010 to its fiscal year ending September
   30, 2011.

   At September 30, 2010, the Fund has reclassified $161,093 to decrease
   undistributed net investment income and $161,093 to decrease accumulated net
   realized loss on investments, to reflect permanent book/tax differences. The
   reclassification has no impact on the net assets of the Fund and presents the
   Fund's capital accounts on a tax basis.


34    Pioneer Value Fund | Annual Report | 9/30/10


   The tax character of distributions paid during the years ended September 30,
   2010 and September 30, 2009 was as follows:



                                2010             2009
                                           
   Distributions paid from:
   Ordinary income              $20,089,651      $36,588,273
   Long-term capital gain                --               --
- ------------------------------------------------------------
     Total                      $20,089,651      $36,588,273
============================================================


   The following shows the components of distributable earnings on a federal
   income tax basis at September 30, 2010:



                                               2010
                                            
   Distributable earnings:
   Undistributed ordinary income               $  12,417,938
   Capital loss carryforward                    (722,904,359)
   Current year post-October loss deferred          (119,558)
   Unrealized appreciation                        22,481,932
- ------------------------------------------------------------
     Total                                     $(688,124,047)
============================================================


   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 may enter into forward foreign currency contracts (contracts) for
   the purchase or sale of a specific foreign currency at a fixed price on a
   future date. 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 (see Note 7).

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 UniCredit S.p.A. (UniCredit),
   earned approximately $86,954 in underwriting commissions on the sale of Class
   A shares during the year ended September 30, 2010.


                              Pioneer Value Fund | Annual Report | 9/30/10    35


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 its respective percentage of adjusted net assets at the beginning
   of the day. During the period, the Fund recognized gains of $2,191,363 in
   settlement of class action lawsuits from several different companies, as
   reflected on the Statement of Operations.

   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 do not pay distribution fees. All
   expenses and fees paid to the transfer agent, Pioneer Investment Management
   Shareholder Services, Inc. (PIMSS), for its services are allocated among
   the classes of shares based on the number of accounts in each class and the
   ratable allocation of related out-of-pocket expenses (see Note 3).

   Distributions to shareowners are recorded as of the ex-dividend date.
   Distributions paid by the Fund with respect to each class of shares are
   calculated in the same manner and at the same time, except that net
   investment income dividends to Class A, Class B, Class C and Class Y shares
   can reflect 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, is
   required to be equal to or in excess of the repurchase price. The
   collateral for all repurchase agreements is held in safekeeping in the
   customer-only account of the Fund's custodian or a subcustodian of the
   Fund. The Fund's investment adviser, Pioneer Investment Management, Inc.
   (PIM), is responsible for determining that the value of the collateral
   remains at least equal to the repurchase price.

H. Securities Lending

   The Fund lends securities in its portfolio to certain broker-dealers or
   other institutional investors. When entering into a securities loan
   transaction, the Fund typically receives cash collateral from the borrower
   equal to at least the fair value of the securities loaned, which is
   invested in temporary investments. Credit Suisse AG, New York Branch, as
   the Fund's securities lending agent, manages the Fund's securities lending
   collateral. The income earned on the investment of collateral is shared
   with the borrower and the lending agent in payment of any rebate due to the
   borrower with respect to the securities loan, and in compensation for the
   lending agent's services to the Fund. The Fund also continues to receive
   payments in lieu of dividends or interest on the securities loaned. Gain or
   loss on the fair value of the loaned securities that may occur during the
   term of the loan will be for the account


36    Pioneer Value Fund | Annual Report | 9/30/10


   of the Fund. The amount of the collateral is required to be adjusted daily
   to reflect any price fluctuation in the fair value of the loaned
   securities. If the required market value of the collateral is less than the
   fair value of the loaned securities, the borrower is required to deliver
   additional collateral for the account of the Fund prior to the close of
   business on that day. The Fund has the right, under the lending agreement,
   to terminate the loan and recover the securities from the borrower with
   prior notice. The Fund is required to return the cash collateral to the
   borrower and could suffer a loss if the value of the collateral, as
   invested, has declined.

2. Management Agreement

PIM, a wholly owned indirect subsidiary of UniCredit, manages the Fund's
portfolio. 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 can
increase or decrease by a maximum of 0.10% based on the investment performance
of the Fund's Class A shares as compared to the Russell 1000 Value Index. The
performance comparison is made for a rolling 36-month period. In addition,
Pioneer contractually limits any positive adjustment of the Fund's management
fee to 0.10% of the Fund's average daily net assets on an annual basis (i.e.,
to a maximum of 0.70% after the performance adjustment). For the year ended
September 30, 2010, the aggregate performance adjustment resulted in a decrease
to the basic fee of $1,812,321. For the year ended September 30, 2010, the
effective management fee (excluding waivers and/or assumption of expenses) was
equivalent to 0.49% of the Fund's 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 as administrative reimbursements. Included in
"Due to affiliates" reflected on the Statement of Assets and Liabilities is
$26,744 in management fees, administrative costs and certain other
reimbursements payable to PIM at September 30, 2010.

3. Transfer Agent

PIMSS, a wholly owned indirect subsidiary of UniCredit, provides substantially
all transfer agent and shareowner services to the Fund at negotiated rates.

In addition, the Fund reimburses PIMSS for out-of-pocket expenses incurred by
PIMSS related to shareholder communications activities such as proxy and
statement mailings, outgoing phone calls and omnibus relationship contracts.
For the year ended September 30, 2010, such out-of-pocket expenses by class of
shares were as follows:

 Class Y                              4,262
- -------------------------------------------
   Total                         $1,153,511
===========================================


Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $227,755, in transfer agent fees and out-of-pocket
reimbursements payable to PIMSS at September 30, 2010.

4. Distribution Plan

The Fund has adopted a Distribution Plan pursuant to Rule 12b-1 of the
Investment Company Act of 1940 with respect to its Class A, Class B and Class C
shares. Pursuant to the Plan, the Fund pays PFD 0.25% of the average daily net
assets attributable to Class A shares as compensation for personal services
and/or account maintenance services or distribution services with regard to
Class A shares. Pursuant to the Plan, the Fund also pays PFD 1.00% of the
average daily net assets attributable to Class B and Class C shares. The fee
for Class B and Class C shares consists of a 0.25% service fee and a 0.75%
distribution fee paid as compensation for personal services and/or account
maintenance services or distribution services with regard to Class B and Class
C shares. Included in "Due to affiliates" reflected on the Statement of Assets
and Liabilities is $10,289 in distribution fees payable to PFD at September 30,
2010.

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 (within 12 months for purchases made on or after
April 1, 2009). Class B shares that are redeemed within five years of purchase
are subject to a CDSC at declining rates beginning at 4.00%, based on the lower
of cost or market value of shares being redeemed. Redemptions of Class C shares
within one year of purchase are subject to a CDSC of 1.00%, based on the lower
of cost or market value of shares being redeemed. Shares purchased as part of
an exchange remain subject to any CDSC that applied to the original purchase of
those shares. There is no CDSC for Class Y shares. Proceeds from the CDSCs are
paid to PFD. For the year ended September 30, 2010, CDSCs in the amount of
$6,221 were paid to PFD.

5. Expense Offset Arrangements

The Fund has entered into certain expense offset arrangements with PIMSS
resulting in a reduction in the Fund's total expenses due to interest earned on
cash held by PIMSS. For the year ended September 30, 2010, the Fund's expenses
were not reduced under such arrangements.

6. Line of Credit Facility

The Fund, along with certain other funds in the Pioneer Family of Funds (the
Funds), participates in a $165 million committed, unsecured revolving line of
credit facility. Borrowings are used solely for temporary or emergency
purposes. The Fund may borrow up to the lesser of the amount available under
the facility or the limits set for borrowing by the Fund's prospectus and the
1940 Act. Interest on borrowings is payable at the higher of the London
Interbank Offered Rate (LIBOR) on the borrowing date plus 1.25% on an
annualized basis or the Federal Funds Rate on the borrowing date plus 1.25% on
an annualized basis. The Funds pay an annual commitment fee for this facility.
The commitment fee is allocated among participating Funds based on an
allocation schedule set forth in the credit agreement. For the year ended
September 30, 2010, the Fund had no borrowings under this agreement.

7. Forward Foreign Currency Contracts

At September 30, 2010, the Fund had entered into various forward foreign
currency contracts that obligate the Fund to deliver or take delivery of
currencies at specified future maturity dates. Alternatively, prior to the
settlement date of a forward foreign currency contract, the Fund may close out
such contract by entering into an offsetting contract. The number of contracts
open during the one month in the year ended September 30, 2010 was 52,799. As
of September 30, 2010, the Fund had no outstanding portfolio or settlement
hedges.

8. Pending Litigation

The Fund currently is involved in a litigation matter in Germany. The Fund
believes the claim is without merit and is defending it vigorously. As of the
Fund's year end, it is reasonably possible that an adverse outcome may result.
Currently, the amount of any judgment cannot be reasonably estimated. Under the
terms of an indemnification agreement, PIM and certain affiliates have agreed
to indemnify the Fund for its losses and costs related to this litigation.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees and Shareowners of
Pioneer Value Fund:
- --------------------------------------------------------------------------------
We have audited the accompanying statement of assets and liabilities of Pioneer
Value Fund ("the Fund"), including the schedule of investments, as of September
30, 2010, and the related statement of operations for the year then ended, the
statements of changes in net assets for each of the two years in the period
then ended, and the financial highlights for each of the five years in the
period then ended. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. We were not engaged to perform an audit of the Fund's internal
control over financial reporting. Our audits included consideration of internal
control over financial reporting as a basis for designing audit procedures that
are appropriate in the circumstances, but not for the purpose of expressing an
opinion on the effectiveness of the Fund's internal control over financial
reporting. Accordingly, we express no such opinion. An audit also includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements and financial highlights, assessing the accounting
principles used and significant estimates made by management, and evaluating
the overall financial statement presentation. Our procedures included
confirmation of securities owned as of September 30, 2010, by correspondence
with the custodian and brokers or by other appropriate auditing procedures
where replies from brokers were not received. We believe that our audits
provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Pioneer Value Fund at September 30, 2010, the results of its operations for the
year then ended, the changes in its net assets for each of the two years in the
period then ended, and the financial highlights for each of the five years in
the period then ended, in conformity with U.S. generally accepted accounting
principles.

 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.

- --------------------------------------------------------------------------------
GENERAL AUDIT COMMITTEE APPROVAL POLICY:
o For all projects, the officers of the Funds and the Fund's auditors will each
  make an assessment to determine that any proposed projects will not impair
  independence.

o Potential services will be classified into the four non-restricted service
  categories and the "Approval of Audit, Audit-Related, Tax and Other
  Services" Policy above will be applied. Any services outside the specific
  pre-approved service subcategories set forth above must be specifically
  approved by the Audit Committee.

o At least quarterly, the Audit Committee shall review a report summarizing the
  services by service category, including fees, provided by the Audit firm as
  set forth in the above policy.

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


    (2) Disclose the percentage of services described in each of paragraphs (b)
   through (d) of this Item that were approved by the audit committee pursuant
   to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

Beginning with non-audit service contracts entered into on or after
May 6, 2003, the effective date of the new SEC pre-approval rules,
the Funds audit committee is required to pre-approve services to
affiliates defined by SEC rules to the extent that the services
are determined to have a direct impact on the operations or
financial reporting of the Fund.  For the years ended
September 30, 2010 and 2009, there were no services provided
to an affiliate that required the Funds audit committee pre-approval.

(f) If greater than 50 percent, disclose the percentage of hours expended on the
principal accountant's engagement to audit the registrant's financial statements
for the most recent fiscal year that were attributed to work performed by
persons other than the principal accountant's full-time, permanent employees.

N/A

(g) Disclose the aggregate non-audit fees billed by the registrant's accountant
for services rendered to the registrant, and rendered to the registrant's
investment adviser (not including any sub-adviser whose role is primarily
portfolio management and is subcontracted with or overseen by another investment
adviser), and any entity controlling, controlled by, or under common control
with the adviser that provides ongoing services to the registrant for each of
the last two fiscal years of the registrant.

The aggregate non-audit fees for the Fund and affiliates, as previously
defined, totaled approximately $8,290 in 2010 and $8,290 in 2009.

(h) Disclose whether the registrant's audit committee of the board of trustees
has considered whether the provision of non-audit services that were rendered to
the registrant's investment adviser (not including any subadviser whose role is
primarily portfolio management and is subcontracted with or overseen by another
investment adviser), and any entity controlling, controlled by, or under common
control with the investment adviser that provides ongoing services to the
registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of
Rule 2-01 of Regulation S-X is compatible with maintaining the principal
accountant's independence.

The Fund's audit committee of the Board of Trustees has
considered whether the provision of non-audit services that
were rendered to the Affiliates (as defined) that were not pre-
approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of
Regulation S-X is compatible with maintaining the principal
accountant's independence.

is acting as the registrants audit committee as specified in
Section 3(a)(58)(B) of the Exchange Act (15 U.S.C. 78c(a)(58)(B)),

N/A

(b) If applicable, provide the disclosure required by Rule 10A-3(d)

from the listing standards for audit committees.

similar functions, about the effectiveness of the registrant's disclosure
controls and procedures (as defined in Rule 30a-2(c) under the Act (17 CFR
270.30a-2(c))) based on their evaluation of these controls and procedures as of
a date within 90 days of the filing date of the report that includes the
disclosure required by this paragraph.

The registrant's principal executive officer
