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

After an extended period of steady economic growth with sustained low
unemployment and low inflation, the U.S. economy ran into difficulty as 2007
drew to a close. Investors in subprime mortgages were forced to mark down the
value of their assets, imperiling leveraged balance sheets. The ensuing credit
crunch forced central banks in the United States and Europe to assume the role
of "lender of last resort" to keep credit markets functioning. Conditions
worsened in the first quarter of 2008, as falling prices, margin calls and
deleveraging continued, the auction-rate preferred market seized up. The U.S.
Federal Reserve expanded its lender-of-last-resort role to include lending to
primary dealers and continued to cut interest rates. By then, recession talk
was widespread as concern grew that falling home prices, rising unemployment,
sharply rising food and energy prices, and disruptions in financial markets
posed a significant threat to economic growth.

Markets reacted poorly to the developments leading up to the difficulties
surrounding Bear Stearns, with fixed-income credit spreads (the difference in
rates between corporate and U.S. government bonds) widening dramatically and
stock markets declining, wiping out the positive returns markets had delivered
in the preceding year. Treasury bond prices rose as the market underwent a
flight to quality. In the six weeks between the Bear Stearns problems and the
end of April, though, there were no further market crises, recession fears
faded in light of positive economic news, and stock markets rallied, recouping
some of their first-quarter losses, while Treasury bond prices fell back.

Over the six-month period ending April 30, 2008, the Dow Jones Industrial
Average fell 7%, the Standard & Poor's 500 Index fell 10% and the NASDAQ
Composite Index fell 16%. The MSCI EAFE Developed Market Index of international
stock markets fell 9%, and the MSCI Emerging Markets Index fell 10%. The U.S.
investment-grade bond market, as measured by the Lehman Brothers Aggregate Bond
Index, was a solid performer over the six months, rising 4%. The U.S.

Letter

high-yield bond market, as measured by the Merrill Lynch High Yield Bond Master
II Index, fell 1% as its higher-coupon yields could not offset a fall in bond
prices triggered by widening credit spreads.

Looking forward, the risk of a 2008 recession seems diminished, but substantial
risks remain in both financial markets and the real economy. On the other hand,
a weak U.S. dollar and substantial fiscal and monetary stimulus are potent
support for the economy. Markets remain volatile, and falling risk tolerances
and deleveraging may depress asset prices in the short term, but equity and
corporate bond valuations look attractive over a longer time horizon unless the
U.S. economy falls into a severe and protracted recession.

Sudden swings in the markets are always to be expected, but they are difficult
to time. Maintaining a long-term time horizon, being diversified, and paying
attention to asset allocation are important investment principles. As always,
we encourage you to work closely with your financial advisor to find the mix of
stocks, bonds and money market assets that is best aligned to your particular
risk tolerance and investment objective and to adhere to a strategic plan
rather than letting emotion drive investment decisions.

Respectfully,

/s/ Daniel K. Kingsbury

PORTFOLIO MANAGEMENT DISCUSSION 4/30/08
- --------------------------------------------------------------------------------

The difficulties that began with the subprime mortgage situation in the summer
of 2007 continued during the six months ended April 30, 2008, as a worsening of
the credit crunch and growing recession fears pulled the U.S. stock market down
to its largest quarterly decline in over five years in the first quarter of
2008. John Carey, manager of the Pioneer Equity Income Fund, provides an update
on the Fund and the factors that influenced performance during the six-month
period.

Q:  Over the past several months, the U. S. economy has experienced rising
    energy and food prices, slower GDP growth, a sluggish real estate market,
    and continued repercussions from the subprime-mortgage situation. How did
    Pioneer Equity Income Fund fare against that barrage of negative economic
    news?

A:  It was a difficult period for the stock market. In the six months ended
    April 30, 2008, Pioneer Equity Income Fund Class A shares returned -6.90%
    at net asset value, including reinvestment of income-dividend and
    capital-gains distributions. On the same, total-return basis, our
    benchmark index, the Russell 1000 Value Index, returned -9.83% over the
    same period, and the Standard & Poor's 500 Index returned -9.63%.
    Meanwhile the average fund in the Lipper Analytical Services
    equity-income category returned -8.82% over the same period. While the
    results for the Fund were better than those of the comparables, they were
    still disappointing to us, just as, we are sure, they were to you.
    However, the stock market does record setbacks from time to time, and the
    key we have always found is to focus on longer-term values and stay
    invested. Indeed, by the end of March the market had started to recover,
    an occurrence that would have been very hard to anticipate had one been
    listening only to the steady drumbeat of dire economic forecasts.

Q:  Please discuss performance during the semiannual reporting period ended
    April 30, 2008, in more detail, including sector exposures and individual
    stock positions that helped or hurt results.

A:  The biggest positive contributors to results for the six months ended April
    30, 2008 were the Fund's stock selections in financial services,
    industrials, information technology, and utilities. Also helping were an
    underweight versus the benchmark Russell 1000 Value Index in financial
    services, which did poorly; and overweights

4


Pioneer Equity Income Fund
- --------------------------------------------------------------------------------

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

    versus the Russell Index in materials and utilities, which did well.
    Detractors from results were the Fund's underweight and stock selection in
    the top-performing energy sector, and our stock selection in health care.

    The Fund benefited considerably by not owning two of the worst-performing,
    large-cap financials, Citigroup and American International Group (AIG),
    though it did, unfortunately, have positions in some of the troubled
    regional banks and savings and loans, including National City, Wachovia,
    and Washington Mutual. Recognizing the serious problems at all three of
    the latter institutions, we did at least sell them from the Fund
    completely before they had done as much damage as they might have. We also
    held one financial that did extremely well: SAFECO rose impressively after
    receiving a premium takeover bid from another insurance company.

    The rest of the portfolio was sprinkled with other winners and losers.
    Gorman-Rupp, the pump manufacturer, rode the strength in the industrials
    sector; Equitable Resources and Questar, with their energy operations,
    prospered as oil and natural gas prices rose; Compass Minerals, provider
    of road salt and fertilizer ingredients, enjoyed record profits; and
    Microchip Technology proved to be a stable refuge in the fast-changing
    world of technology. On the negative side, bad news from Merck in regard
    to one of its prescription anti-cholesterol drugs sent the shares into a
    tailspin. Johnson Controls saw weakness in both its automotive interiors
    business and its building controls division. Still, there were more
    positive than negative contributors from a relative-performance
    standpoint, and consequently the Fund did outperform its benchmark as well
    as our peer Funds.

Q:  Oftentimes a weak stock market presents investment opportunities. Did you
    find some in the past six months, and, overall, can you discuss changes
    you made to the portfolio?

A:  In the half-year ended April 30, 2008, we added nine names to the portfolio
    and eliminated 14. We did see opportunities in the market, but we also
    concluded that some of the Fund's existing holdings had suffered
    impairments in earnings power, both through their own deficient
    management and because of forces in the economy. So we were sellers as
    well as buyers of securities during the period. Among the stocks we
    introduced to the Fund were: Nucor, a company that began with a single
    "mini-mill" back

                                                                               5

    in 1968 and is now perhaps the most important steel maker in the country;
    Teck Cominco, a Canadian-based miner of zinc, copper, gold, coal, and
    other minerals; VF, whose clothing brands include Wrangler and Lee blue
    jeans and The North Face outdoor wear; Hershey, chocolate confectioner
    extraordinaire; and Northern Trust, provider of fiduciary, asset custody,
    and investment management services.

    Aside from the sales we already mentioned in the financial sector, we sold
    a number of stocks from the Fund for which we could no longer see
    compelling prospects. Macy's, a struggling department store company,
    Masco, a challenged manufacturer of plumbing supplies and hardware, and
    Great Plains Energy, an electric utility with uncertain growth potential,
    were three examples.

Q:  With all the uneasiness in the markets since the middle of 2007, though
    against the backdrop of the aggressive actions taken by the U. S. Federal
    Reserve and the U. S. government in response to that uneasiness, what is
    your outlook for the coming months?

A:  By no means are we "out of the woods" yet in regard to the problems in the
    financial sector and the housing industry. The effects of those problems,
    plus the very high energy prices, on consumer spending continue to be
    felt. At the same time, many American companies have substantial business
    overseas, where economic growth has been strong of late. Actually,
    corporate earnings so far this calendar year have been remarkably good
    outside the financial sector. The recovery in the stock market from the
    lows in the middle of March 2008 would seem to indicate that investors
    have noticed. What one must also keep in mind is that the stock market
    does not always respond so much to near-term economic news as it does to
    potential developments six to twelve months in the future. That is why
    the stock market is sometimes called a "discounting mechanism."

    Nevertheless, the environment is not without its risks, and so we remain
    "defensive" in our approach. For the coming months, we are especially
    attracted to some of the sectors in which an investor can find successful
    companies with self-financing capability and significant international as
    well as domestic business. Certainly there are companies in information
    technology, health care, and consumer staples that have those qualities.
    On a longer-term

    basis, we also still like many companies in the materials and industrials
    sectors. Within the beleaguered financial sector, we believe there will be
    good opportunities "as the coast clears" and we again have decent
    visibility on the companies' operations.

     We appreciate your faithful support.

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

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

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.

The Performance of Class Y shares for the period prior to the commencement of
operation of Class Y shares on July 2, 1998 reflects the NAV performance of the
Fund's Class A shares. The performance does not reflect differences in
expenses, including the Rule 12b-1 fees applicable to Class A shares. Since
fees for Class A shares are generally higher than those of Class Y shares, the
performance shown for Class Y shares prior to their inception on July 2, 1998
would have been higher. Class Y shares are not subject to sales charges and are
available for limited groups of eligible investors, including institutional
investors. All results are historical and assume the reinvestment of dividends
and capital gains. Other share classes are available for which performance and
expenses will differ.

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

The performance table and graph do not reflect the deduction of fees and taxes
that a shareowner would pay on Fund distributions or the redemption of Fund
shares.

Call 1-800-225-6292 or visit www.pioneerinvestments.com for the most recent
month-end performance results. Current performance may be lower or higher than
the performance data quoted.

The performance data quoted represents past performance, which is no guarantee
of future results. Investment return and principal value will fluctuate, and
shares, when redeemed, may be worth more or less than their original cost.

Performance for periods prior to the inception of Class Z shares reflects the
NAV performance of the Fund's Class A shares. The performance does not reflect
differences in expenses, including the Rule 12b-1 fees applicable to Class A
shares. Since fees for Class A shares are generally higher than those of Class Z
shares, the performance shown for Class Z shares prior to their inception July
6, 2007 would have been higher. Class Z shares are not subject to sales charges
and are available for limited groups of eligible 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.

The net expense ratio reflects contractual expense limitations currently in
effect through 3/1/10 for Class Z Shares. There can be no assurance that Pioneer
will extend the expense limitations beyond such time. Please see the prospectus
and financial statements for more information.

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

                                                                              15

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.

    R, Class Y and Class Z shares, respectively, multiplied by the average
    account value over the period, multiplied by 182/366 (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.

1. Organization and Significant Accounting Policies
Pioneer Equity Income 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 current income and
long-term growth of capital from a portfolio consisting primarily of income
producing equity securities of U.S. corporations.

The Fund offers six classes of shares - Class A, Class B, Class C, Class R,
Class Y and Class Z shares. Class Z shares were first publicly offered on July
6, 2007. Each class of shares represents an interest in the same portfolio of
investments of the Fund and have equal rights to voting, redemptions, dividends
and liquidation, except that each class of shares can bear different transfer
agent and distribution fees and have exclusive voting rights with respect to
the distribution plans that have been adopted by Class A, Class B, Class C, and
Class R shareowners, respectively. There is no distribution plan for Class Y
and Class Z shareowners.

The Fund's financial statements have been prepared in conformity with U.S.
generally accepted accounting principles that require the management of the
Fund to, among other things, make estimates and assumptions that affect the
reported amounts of assets and liabilities, the disclosure of contingent assets
and liabilities at the date of the financial statements, and the reported
amounts of income, expenses and gains and losses during the reporting period.
Actual results could differ from those estimates.

At times, the Fund's investments may represent industries or industry sectors
that are interrelated or have common risks, making it more susceptible to any
economic, political or regulatory developments or other risks affecting these
industries or sectors. The Fund's prospectuses contain information regarding
the Fund's principal risks. Please refer to those documents when considering
the Fund's investment risks.

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:

38


Pioneer Equity Income Fund
- --------------------------------------------------------------------------------

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

A.  Security Valuation

    Security transactions are recorded as of trade date. The net asset value
    of the Fund is computed once daily, on each day the New York Stock
    Exchange (NYSE) is open, as of close of regular trading on the NYSE. In
    computing the net asset value, securities are valued at the last sale
    price on the principal exchange where they are traded. Securities that
    have not traded on the date of valuation, or securities for which sale
    prices are not generally reported, are valued at the mean between the last
    bid and asked prices. Securities for which market quotations are not
    readily available are valued at their fair values as determined by, or
    under the direction of, the Board of Trustees. Trading in foreign
    securities is substantially completed each day at various times prior to
    the close of the NYSE. The values of such securities used in computing the
    net asset value of the Fund's shares are determined as of such times. The
    Fund may also use the fair value of a security, including a non-U.S.
    security, when the closing market price on the principal exchange where
    the security is traded no longer reflects the value of the security. At
    April 30, 2008, there were no securities fair valued. Temporary cash
    investments are valued at cost which approximates market value.

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

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

B.  Federal Income Taxes

    It is the Fund's policy to comply with the requirements of the Internal
    Revenue Code applicable to regulated investment companies and to
    distribute all of its taxable income and net realized capital gains, if
    any, to its shareowners. Therefore, no federal income tax provision is
    required. Tax years prior to 2004 are

                                                                              39


Pioneer Equity Income Fund
- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 4/30/08 (unaudited)                  (continued)
- --------------------------------------------------------------------------------

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

    The amounts and characterizations of distributions to shareowners for
    financial reporting purposes are determined in accordance with federal
    income tax rules. Therefore, the sources of the Fund's distributions may
    be shown in the accompanying financial statements as from or in excess of
    net investment income or 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.

    The tax character of current year distributions will be determined at the
    end of the fiscal year. The tax character of distributions paid during the
    year ended October 31, 2007 was as follows:

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


                                  2007
- -----------------------------------------------------------------------------
                          
  Distributions paid from:
  Ordinary Income             $ 30,337,537
  Long-term capital gain        99,680,747
                              ------------
    Total                     $130,018,284
                              ============

- -----------------------------------------------------------------------------
    The following shows the components of distributable earnings on a
     federal income tax basis at October 31, 2007:
- ------------------------------------------------------------------------------


                                        2007
- -----------------------------------------------------------------------------
                               
  Undistributed ordinary income    $    747,003
  Undistributed long-term gain       78,306,276
  Unrealized appreciation           379,022,224
                                   ------------
    Total                          $458,075,503
                                   ============

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

    The difference between book basis and tax-basis unrealized appreciation is
    attributable to the tax adjustments on partnerships, REIT holdings, and
    preferred stocks.

C.  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

40


Pioneer Equity Income Fund
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
    S.p.A. (UniCredit) earned approximately $154,267 in underwriting
    commissions on the sale of Class A shares during the six months ended
    April 30, 2008.

D.  Class Allocations

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

    Distribution fees are calculated based on the average daily net asset
    value attributable to Class A, Class B, Class C and Class R shares of the
    Fund, respectively. Class Y and Class Z shares are not subject to a
    distribution plan (see Note 4). Shareowners of each class participate in
    all expenses and fees paid to the transfer agent, Pioneer Investment
    Management Shareholder Services, Inc. (PIMSS), for its services, which are
    allocated based on the number of accounts in each class and the ratable
    allocation of related out-of-pocket expenses (see Note 3).

    Distributions to shareowners are recorded as of the ex-dividend date.
    Distributions paid by the Fund with respect to each class of shares are
    calculated in the same manner, at the same time, and in the same amount,
    except that Class A, Class B, Class C, Class R, Class Y and Class Z shares
    can bear different transfer agent and distribution expense rates.

E.  Repurchase Agreements

    With respect to repurchase agreements entered into by the Fund, the value
    of the underlying securities (collateral), including accrued interest
    received from counterparties, is required to be at least equal to or in
    excess of the value of the repurchase agreement at the time of purchase.
    The collateral for all repurchase agreements is held in safekeeping in the
    customer-only account of the Fund's custodian, or subcustodians. The
    Fund's investment adviser, Pioneer Investment Management, Inc. (PIM), is
    responsible for determining that the value of the collateral remains at
    least equal to the repurchase price.

                                                                              41

NOTES TO FINANCIAL STATEMENTS 4/30/08 (unaudited)                  (continued)
- --------------------------------------------------------------------------------
F.  Securities Lending

    The Fund lends securities in its portfolio to certain broker-dealers or
    other institutional investors. When entering into a loan, the Fund
    receives collateral and earns income in the form of negotiated lenders'
    fees. The Fund also continues to receive interest or payments in lieu of
    dividends on the securities loaned. Gain or loss on the fair value of the
    loaned securities that may occur during the term of the loan will be for
    the account of the Fund. The loans are secured by collateral which is
    required to be at least 102%, at all times, of the fair value of the
    securities loaned. The amount of the collateral is required to be adjusted
    daily to reflect any price fluctuation in the value of the loaned
    securities. The Fund has the right under the lending agreements to recover
    the securities from the borrower on demand. The Fund invests cash
    collateral in cash equivalent investments.

2. Management Agreement

PIM, a wholly owned indirect subsidiary of UniCredito Italiano, manages the
Fund's portfolio. PIM receives a basic fee that is calculated at the annual
rate of 0.60% of the Fund's average daily net assets up to $10 billion and
0.575% of the excess over $10 billion. For the six months ended April 30, 2008,
the net management fee was equivalent to 0.60% of the average daily net assets.

Pioneer has contractually agreed to limit ordinary operating expenses to the
extent required to reduce Class Z expenses to 0.85% of the average daily net
assets attributable to Class Z shares. This expense limitation is in effect
through March 1, 2011 for Class Z shares.

In addition, under the management and administrative agreements, certain other
services and costs, including accounting, regulatory reporting, and insurance
premiums, are paid by the Fund. Included in "Due to Affiliates" reflected on
the Statement of Assets and Liabilities is $21,130 in management fees,
administrative costs and certain other services payable to PIM at April 30,
2008.

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.
Included in "Due to Affiliates" reflected on the

42


Pioneer Equity Income Fund
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
Statement of Assets and Liabilities is $118,971 in transfer agent fees payable
to PIMSS at April 30, 2008.

4. Distribution and Service Plans

The Fund adopted a Plan of Distribution with respect to Class A, Class B, Class
C and Class R shares (Class A Plan, Class B Plan, Class C Plan, Class R Plan)
in accordance with Rule 12b-1 of the Investment Company Act of 1940. Pursuant
to the Plan, the Fund pays PFD 0.25% of the Fund's 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 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. Pursuant to
the Plan, the Fund pays PFD 0.50% of the average daily net assets attributable
to Class R shares as compensation for distribution services. For the period
from November 1, 2007 through January 31, 2008, PFD was reimbursed under the
Plan of Distribution for distribution expenses in an amount of up to 0.25% of
the average daily net assets attributes to Class A shares. Included in due to
affiliates reflected on the Statement of Assets and Liabilities is $14,963 in
distribution fees payable to PFD at April 30, 2008.

The Fund also has adopted a separate service plan for Class R shares (Service
Plan). The Service Plan authorizes the Fund to pay as compensation to
securities dealers, plan administrators or other service organizations that
agree to provide certain services to retirement plans or plan participants
holding shares of the Fund a service fee of up to 0.25% of the Fund's average
daily net assets attributable to Class R shares held by such plans in
reimbursement for actual expenditures.

In addition, redemptions of Class A, Class B and Class C 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 purchases. Class B shares redeemed within five years of purchase are
subject to a CDSC at declining rates beginning at 4.00%, based on the lower
cost or market value of shares being redeemed. Redemptions of Class C

                                                                              43


Pioneer Equity Income Fund
- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 4/30/08 (unaudited)                  (continued)
- --------------------------------------------------------------------------------
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. Proceeds from the CDSCs
are paid to PFD. For the six months ended April 30, 2008, CDSCs in the amount
of $110,694 were paid to PFD.

5. Commission Recapture and Expense Offset Arrangements

Effective July 15, 2005, the Fund has entered into commission recapture
arrangements with brokers with whom PIM places trades on behalf of the Fund
where they provide services to the Fund in addition to trade execution. These
services included payments of certain expenses on behalf of the Fund. For the
six months ended April 30, 2008, expenses were not reduced under this
agreement. In addition, the Fund has entered into certain expense offset
arrangements with PIMSS resulting in a reduction in the Fund's total expenses
due to interest earned on cash held by PIMSS. For the six months ended April
30, 2008, the Fund's expenses were reduced by $25,026 under such arrangements.

6. Line Of Credit Facility

The Fund, along with certain others in the Pioneer Family of Funds (the Funds),
collectively participate in a $200 million committed, unsecured revolving line
of credit facility. Borrowings are used solely for temporary or emergency
purposes. The Fund may borrow up to the lesser of $200 million or the limits
set by its prospectus for borrowings. Interest on collective borrowings is
payable at the Federal Funds Rate plus 1/2% on an annualized basis. The Funds
pay an annual commitment fee for this facility. The commitment fee is allocated
among such Funds based on their respective borrowing limits. For the six months
ended April 30, 2008, the Fund had no borrowings under this agreement.

8. New Pronouncements

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157), was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of
SFAS 157 will have on the Fund's financial statement disclosures.

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

ADDITIONAL INFORMATION (unaudited)

Effective January 1, 2008, the fund may invest up to 20% of its total assets in
equity and debt securities of non-U.S. corporate issuers and debt securities of
non-U.S. government issuers. The fund will not invest more than 5% of its total
assets in the securities of emerging markets issuers. Investing in non-U.S.
issuers may involve unique risks compared to investing in securities of U.S.
issuers. These risks are more pronounced for issuers in emerging markets or to
the extent the fund invests significantly in one region or country. These risks
may include:

                                                                              45

APPROVAL OF INVESTMENT ADVISORY AGREEMENT
- --------------------------------------------------------------------------------

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

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

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

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

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

                                                                              47

- --------------------------------------------------------------------------------
APPROVAL OF INVESTMENT ADVISORY AGREEMENT                          (continued)
- --------------------------------------------------------------------------------
for the Fund's operations. The Trustees considered the fees paid to PIM for the
provision of such services.

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

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

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

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

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

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

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

                                                                              49

- --------------------------------------------------------------------------------
APPROVAL OF INVESTMENT ADVISORY AGREEMENT                          (continued)
- --------------------------------------------------------------------------------
Economies of Scale
The Trustees considered the economies of scale with respect to the management
of the Fund, whether the Fund had appropriately benefited from any economies of
scale, and whether there was potential for realization of any further economies
of scale. The Trustees concluded that, because of the breakpoints in the
management fee schedule and the reduced fee rates above certain asset levels,
any perceived or potential economies of scale would be shared between PIM and
the Fund.

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

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

 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.
