President's Letter

Dear Shareowner,

During the first three quarters of 2011, the U.S. economy struggled to gain
solid footing. The economy went through a soft patch in the first half, and the
second half, so far, has been highlighted by the U.S. government's battle over
the debt ceiling and Standard & Poor's downgrade of the U.S. Treasury's credit
rating from the top rating of "AAA" for the first time in history. After
rallying nicely in the first half, U.S. equity markets reacted sharply this
summer to the political stalemate and the downgrade. There has been continued
pressure on equities due to concerns about the growing European sovereign-debt
crisis and its potential impact on the global economy.

Despite legitimate reasons for concern, we believe there are also reasons for
optimism that the U.S. economy will continue to exhibit low to flat growth and
not head into a severe recession. Corporations continue to post solid earnings
and, for the most part, are maintaining their positive earnings outlooks. They
also have strong balance sheets with improved net leverage and high cash
levels. Auto production has rebounded following the Japanese supply chain
interruptions caused by the earthquake and tsunami last spring. Retail sales
growth year-over-year has remained strong despite low consumer confidence. And
despite high unemployment in the U.S., private sector employment has grown
consistently since February 2010. There are certainly risks to our outlook,
including possible contagion from the European sovereign-debt and banking
crisis, the fiscal drag from federal and state budget cuts in the U.S., as well
as potential "negative feedback loops" from capital market volatility. But
broadly speaking, we think this subpar economic recovery is consistent with
recoveries from other "balance sheet"-caused recessions.

The difficult recovery process has been accompanied by wide market swings.
While this is a challenging environment, our investment professionals continue
to focus on finding good opportunities to invest in both equity and bond
markets using the same disciplined approach Pioneer has used since 1928. Our
approach is to identify undervalued individual securities with the greatest
potential for success, carefully weighing risk against reward. Our teams of
investment professionals continually monitor and analyze the relative
valuations of different sectors and securities globally to help build
portfolios that we believe can help you achieve your investment goals.

Portfolio Management Discussion | 9/30/11

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, 2011. Mr. Peckham is responsible for the
day-to-day management of the Fund's portfolio. He is supported by Mr. Wright.

Q    Over the 12 months ended September 30, 2011, value stocks underperformed
     growth stocks. Could you discuss the investment environment for value
     stocks over the 12-month period and explain why they underperformed the
     growth stock universe?

A    Value underperformed growth over the 12-month period largely due to the
     poor performance of the financials sector. Within financials, banks
     returned -11%, insurance stocks returned -12%, and diversified financials
     returned -29%. The one safe haven in financials was real estate investment
     trusts (REITs), which had a slightly positive return for the year.

     In 2011, financials proved the text book definition of value traps - stocks
     that appear to be cheap but turn out to be very expensive. As we began the
     Fund's fiscal year, it was easy to make the case that stocks of banks and
     brokers were cheap. After all, on traditional valuation measures like
     price-to-book value and price-to-earnings, the stocks appeared very
     inexpensive compared with their history and compared with stocks in other
     sectors.

     Unfortunately, the projected earnings failed to materialize and doubts
     emerged regarding the quality of reported book values. Regarding earnings,
     a host of issues hurt the sector, including slow loan growth and new
     regulations. With respect to book values, questions largely focused on what
     financial institutions held in mortgages, European sovereign bonds, and
     derivatives.

     However, the primary issue for the financials sector over the 12-month
     period was weak economic growth. In the end, financials are a levered bet
     on the economy. When the economy is weak, financials struggle to perform,
     as few people or businesses need to take out new loans, and those with
     loans struggle to repay them. We think with a better economy, earnings
     likely would have materialized and investors would have had more confidence
     in reported book values.

Q    How did the Fund perform in that environment over the 12 months ended
     September 30, 2011?

A    Pioneer Value Fund Class A shares returned -5.39% over the 12 months ended
     September 30, 2011, while the Fund's benchmark, the Russell 1000 Value
     Index, returned -1.89%. Over the same period, the average return of


4    Pioneer Value Fund | Annual Report | 9/30/11


     the 501 mutual funds in Lipper's Large-Cap Value Funds category was -3.54%.

Q    The Fund underperformed both the Russell 1000 Value Index and its Lipper
     peers over the 12-month period. Could you highlight some of the factors
     behind the Fund's underperformance relative to the overall market?

A    The Fund's primary downfall over the past 12 months was our misplaced
     optimism on the pace of the global economic recovery. We mistakenly
     believed the economic recovery would follow the path of other post-war
     recoveries, with growth smartly reverting to trend-line rates. We
     positioned the Fund's portfolio accordingly. This, of course, proved
     incorrect as structural issues, policy mistakes, and several exogenous
     events hampered the recovery.

     The largest structural issue was, and remains, high debt levels. Consumers
     have been reducing debt from very high levels, and that undoubtedly hurt
     the biggest component of gross domestic product (GDP): consumer spending.
     Governments, in contrast, have continued to add debt at a furious pace,
     raising concerns about an ultimate day of reckoning when budgets are
     slashed and taxes raised. In sum, we misjudged the debt headwind.

     On the policy front, it is not clear that the Federal Reserve's (the Fed's)
     actions to stimulate the economy did much except to raise the cost of
     energy and food, while punishing savers. Similarly, the government's nearly
     $1 trillion stimulus program has failed to stimulate much growth and has
     had little obvious impact on the very high unemployment rate. In addition,
     a torrent of new and proposed laws and regulations have added an additional
     layer of business uncertainty. Looking back, it appears that we gave policy
     makers too much credit.

     The list of economically damaging exogenous events occurring in 2011 is
     noteworthy. The Japanese earthquake/tsunami tragedy last March disrupted
     the global supply chain and, in particular, hurt the automotive and
     technology industries. The so-called "Arab Spring" in the Middle East,
     which saw several longstanding authoritarian regimes overthrown through
     popular uprisings, likely contributed to a spike in oil prices. In the
     United States, floods in the Midwest, drought in the southwest, and a major
     hurricane hitting the east coast as well as numerous other severe weather
     events likely dampened economic activity. Thailand also has been suffering
     from terrible flooding that has further disrupted technology and automotive
     supply chains. We believe a stronger global economy would have likely
     powered through this streak of bad luck. Our mistake in managing the Fund
     over the 12 months ended September 30, 2011, was not adequately accounting
     for the effects of such events in light of a weaker-than-expected recovery.


                               Pioneer Value Fund | Annual Report | 9/30/11    5


Q    What specific sector allocations or portfolio holdings aided or detracted
     from the Fund's relative performance over the 12-month period ended
     September 30, 2011?

A    The Fund's sector weightings were a modest drag on performance over the
     period. In general, the Fund was overweight the cyclical sectors and
     underweight defensive sectors. This proved to be the wrong call as
     materials, industrials, and technology underperformed, while health care,
     consumer staples, telecommunications, and utilities outperformed. The Fund
     did benefit by our decision to overweight consumer discretionary and
     energy, while remaining underweight the difficult financials sector.

     Our stock picks proved the biggest drag on the Fund's performance over the
     12-month period. Not surprisingly, the list of "bottom 10" performers held
     in the portfolio is dominated by cyclical names that suffered due to a
     combination of real and feared macroeconomic concerns, regulatory fallout,
     and self-inflicted wounds.

     Within financials, Fund positions in Bank of America, Goldman Sachs,
     regional bank Comerica, and insurer/asset manager Ameriprise significantly
     hurt returns. In the case of Bank of America, we misjudged the ongoing
     effects of the firm's deeply troubled mortgage business. Regarding Goldman
     Sachs, we underestimated the impact of regulatory reform. For Comerica, our
     estimates for loan growth proved too optimistic. In contrast, we were
     pleased with Ameriprise's business performance, however the market took a
     different view. The Fund continues to hold Ameriprise, but we sold the
     positions in the other stocks.

     Within the commodity sensitive sectors, the Fund's holdings in chemical
     maker LyondellBasell, refiner Marathon Petroleum, and miner Freeport
     McMoRan Copper & Gold underperformed due to macroeconomic concerns.
     However, the businesses have continued to perform well and we have
     maintained the Fund's positions

     Holdings in the technology sector proved especially disappointing for the
     Fund over the last 12 months. Xerox failed to meet our expectations in its
     core copier/printing business and its outsourced services segment. We
     exited the Xerox position and added to the Fund's holdings in more
     promising technology names, including Qualcomm and Oracle. Chip equipment
     maker Applied Materials also disappointed as demand stalled due to
     macroeconomic uncertainty. We continue to hold Applied Materials in the
     Fund's portfolio, as we expect equipment demand will improve as chip makers
     ramp up capital expenditures.

     The Fund's top-performing stocks over the 12 months ended September 30,
     2011, featured a mix of stable defensive names, including Verizon and Coca-
     Cola, and a number of cyclical stocks in the media and energy industries.

6    Pioneer Value Fund | Annual Report | 9/30/11


     In media, News Corp, CBS, and Comcast were top performers for the Fund.
     News Corp was a very controversial stock during the period as the company
     responded to charges of "phone hacking" by employees at one of its London
     newspapers. Management wisely took strong action to reduce the negative
     effects, including shutting down the paper, dramatically raising the
     dividend, repurchasing a significant amount of stock, and making modest
     changes to improve corporate governance.

     In contrast, CBS and Comcast were far less controversial and outperformed
     during the period, as both companies' management teams executed on their
     core business strategies. In the case of CBS, the company benefited from a
     strong advertising market and continued efforts to generate more money from
     its hit TV shows. For Comcast, the company continued to find ways to boost
     the profitability of its industry leading cable system. In addition, the
     company purchased a stake in NBC Universal, a deal we believe will drive
     profits for years to come.

     In energy, integrated natural gas company Williams and oil company Chevron
     were top performers for the Fund over the 12-month period. In 2010,
     Williams changed CEOs, an event we judged would lead to a much-needed
     restructuring of the company. We started buying the stock for the Fund
     shortly after the CEO change. In early 2011, Williams announced it would
     split into a pipeline company and an exploration & production company. As
     we had hoped, the market reacted favorably to the news and unlocked the
     value in Williams's stock. We subsequently sold the Fund's position at a
     solid profit.

     Chevron was a less-exciting investment for the Fund over the past 12
     months, but nonetheless a very profitable one. While Chevron clearly
     benefited from higher oil prices, management continued to drive
     better-than-expected profitability and returns from the company's refining
     and exploration & production segments. Along the way, Chevron raised its
     dividend twice and repurchased a significant amount of stock. The Fund
     continues to hold the stock as it remains cheap relative to the upside
     potential we see when several major projects start generating profits in a
     few years.

Q    What is your outlook for the final quarter of 2011 and beyond?

A    Stock markets fell apart in the third quarter of 2011 as pessimism
     approached a peak. In our view, the market was pricing in a very high
     probability of a global recession. We did not share the view, and used the
     opportunity to add to the Fund's higher-conviction holdings and open new
     positions in stocks that had suffered badly in recent months.

     As we write, the final quarter of 2011 has gotten off to a good start,
     including one of the best Octobers in the history of the equity market. So
     far, economic data have failed to confirm a global recession. In addition,
     Europe


                               Pioneer Value Fund | Annual Report | 9/30/11    7


     has taken positive steps to address its debt crisis. Finally, third quarter
     earnings reports from many of the Fund's holdings have been positive, with
     outlooks generally better than feared. While nothing is certain, we remain
     encouraged, as it appears that progress is being made and equity valuations
     have remained attractive.

     The Fund continues to focus on cheap, quality stocks with an emphasis on
     names with low-valuation multiples, high returns on equity, solid free cash
     flow, and reasonable debt levels. We maintain a bias towards cyclical
     sectors in the portfolio, as that is where we have been finding the most
     value.

Index Definition
--------------------------------------------------------------------------------
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. It is not possible
to invest directly in an index.

The index defined here pertains to the "Value of $10,000 Investment" and "Value
of $5 Million Investment" charts on pages 11-14.

Call 1-800-225-6292 or visit us.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.

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

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

The performance 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.

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

Class C shares held for less than one year are also subject to a 1% contingent

you paid a 1% sales charge, your returns would be lower than those shown above.
"If Held" results represent the percent change in net asset value per share.
Returns would have been lower had sales charges been reflected. 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

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.

Comparing Ongoing Fund Expenses

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

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

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

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

Using the Tables
--------------------------------------------------------------------------------
Actual Expenses

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

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

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

* Expenses are equal to the Fund's annualized expense ratio of 1.02%, 2.62%,
  2.14% and 0.61% for Class A, Class B, Class C and Class Y shares,
  respectively, multiplied by the average account value over the period,
  multiplied by 183/365 (to reflect the one-half year 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 | 9/30/11

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 | 9/30/11


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 period. 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, 2011, there were no securities that were valued using fair
     value methods (other than securities that were valued using prices supplied
     by independent pricing services). Inputs used when applying fair value
     methods to value a security may include credit ratings, the financial
     condition of the company, current market conditions and comparable
     securities. 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.


                              Pioneer Value Fund | Annual Report | 9/30/11    33


     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 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.

     Under the recently enacted Regulated Investment Company Modernization Act
     of 2010, the Fund will be permitted to carry forward capital losses
     incurred in taxable years beginning after December 22, 2010 for an
     unlimited period. However, any losses incurred during those future years
     will be required to be utilized prior to the losses incurred in
     pre-enactment tax years. As a result of this ordering rule, pre-enactment
     capital loss carryforwards may be more likely to expire unused.
     Additionally, post enactment capital losses that are carried forward will
     retain their character as either short-term or long-term capital losses
     rather than being considered all short-term as under previous law.


34    Pioneer Value Fund | Annual Report | 9/30/11


     At September 30, 2011, the Fund reclassified $484,883 to decrease net
     investment income, and $484,883 to decrease accumulated net realized loss
     on investments and foreign currency transactions to reflect permanent
     book/tax differences. The reclassification has no impact on the net asset
     value of the Fund and is designed to present the Fund's capital accounts on
     a tax basis.

     At September 30, 2011, the Fund had a net capital loss carryforward of
     $702,495,219, of which the following amounts will expire between 2017 and
     2018 if not utilized: $382,949,757 in 2017 and $319,545,462 in 2018.

     The tax character of distributions paid during the years ended September
     30, 2011, and September 30, 2010, were as follows:



     ---------------------------------------------------------------------------
                                                  2011                   2010
     ---------------------------------------------------------------------------
                                                            
     Distributions paid from:
     Ordinary income                       $22,406,572            $20,089,651
     Long-term capital gain                         --                     --
     ---------------------------------------------------------------------------
        Total                              $22,406,572            $20,089,651
     ===========================================================================


  The following shows the components of distributable earnings on a federal
  income tax basis at September 30, 2011:



     ---------------------------------------------------------------------------
                                                                        2011
     ---------------------------------------------------------------------------
                                                           
     Distributable earnings:
     Undistributed ordinary income                            $    8,247,376
     Capital loss carryforward                                  (702,495,219)
     Unrealized depreciation                                     (69,094,332)
     ---------------------------------------------------------------------------
        Total                                                 $ (763,342,175)
     ===========================================================================


     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).


                              Pioneer Value Fund | Annual Report | 9/30/11    35


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 $65,594 in underwriting commissions on the sale of
     Class A shares during the year ended September 30, 2011. During the year,
     the Fund recognized gains of $3,390,398 in settlement of class action
     lawsuits from several different companies, as reflected on the Statement of
     Operations.

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.

     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 value of the securities loaned, which is invested in
     temporary investments.


36    Pioneer Value Fund | Annual Report | 9/30/11


     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 value of the loaned securities
     that may occur during the term of the loan will be for the account of the
     Fund. The amount of the collateral is required to be adjusted daily to
     reflect any price fluctuation in the value of the loaned securities. If the
     required market value of the collateral is less than the 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, 2011, the aggregate performance adjustment resulted in a decrease
to the basic fee of $1,597,791. For the year ended September 30, 2011, the
effective management fee (excluding waivers and/or assumption of expenses) was
equivalent to 0.50% 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
$817 in management fees, administrative costs and certain other reimbursements
payable to PIM at September 30, 2011.

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.


                              Pioneer Value Fund | Annual Report | 9/30/11    37


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, 2011, such out-of-pocket expenses by class of
shares were as follows:



--------------------------------------------------------------------------------
Shareholder Communications:
--------------------------------------------------------------------------------
                                                                 
Class A                                                             $1,469,870
Class B                                                                  9,329
Class C                                                                  7,675
Class Y                                                                  4,438
--------------------------------------------------------------------------------
   Total                                                            $1,491,312
================================================================================


Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $368,237 in transfer agent fees and out-of-pocket reimbursements
payable to PIMSS at September 30, 2011.

4. Distribution Plan

The Fund has adopted a distribution plan ("the 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 $8,720 in distribution fees payable to PFD at September 30,
2011.

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 12 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%, 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, 2011,
CDSCs in the amount of $4,391 were paid to PFD.


38    Pioneer Value Fund | Annual Report | 9/30/11


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, 2011, 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, 2011, the Fund had no borrowings under this agreement.

7. Forward Foreign Currency Contracts

At September 30, 2011, 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 Fund's gross forward
currency settlement contracts receivable and payable were $886,875 and
$897,591, respectively, resulting in a net payable of $10,716. The average
value of contracts open during the year ended September 30, 2011 was
$1,379,043. There were no open portfolio hedges at September 30, 2011.

9. Pending Litigation

The Fund is currently involved in a litigation matter in Germany. A German
financial intermediary, now deceased, apparently opened an account in the name
of the plaintiffs, a married couple, and later misappropriated the assets. The
plaintiffs filed a lawsuit against the Fund and an affiliate seeking recovery
for the misappropriated assets, alleging negligence and breach of contract. The
Fund believes that these claims are without merit and is defending the matter
vigorously. As of year ended September 30, 2011, it is reasonably possible that
an adverse outcome may result. Currently, the amount of any judgment cannot
reasonably be 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 should there be an adverse outcome.

10. Subsequent Events

In preparing these financial statements, PIM has evaluated the impact of all
events and transactions for potential recognition or disclosure and has
determined that there were no subsequent events requiring recognition or
disclosure in the financial statements.

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, 2011, 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, 2011, 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, 2011, 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.

  pre-approved service subcategories set forth above must be specifically
  approved by the Audit Committee.
