President's Letter

Dear Shareowner,

A few months into 2014, we still expect U.S. economic growth for the year to be
in the 2.5% to 3% range, despite some weaker economic data releases during the
winter months driven in large part by harsh weather across much of the
continental U.S. While unemployment remains high, employment has been rising
steadily. Consumer incomes, savings, wealth, and debt-servicing capacity have
been solid buttresses for the recovering housing and auto industries. Industrial
activity is growing only moderately, but current corporate profits are generally
solid and balance sheets appear able to support needed capital spending and
dividend* payouts. A modestly improving European economy and continuing economic
improvement in Japan appear likely to result in improving global growth in 2014,
further supporting the U.S. economy. In addition, we feel that continuing slack
in labor markets and capacity utilization offer the potential for continuing
growth without bottlenecks and rising inflation.

After observing the strengthening economic trends, the Federal Reserve System
(the Fed) has begun scaling back its QE (quantitative easing) program, but
short-term interest rates remain near zero, and while Fed Chair Janet Yellen has
suggested that rates may be raised roughly six months after the QE program is
fully tapered, that would still place the potential rate hike sometime in 2015.

There are certainly risks and uncertainties still facing the global economy as
2014 moves along. The European economy, while improving, remains weak, the
Japanese economy faced a tax hike this spring, and a number of emerging market
countries are experiencing difficulties. There are also geopolitical worries
abroad, such as Russia's aggressive move against the Ukraine, and more potential
political fights at home, especially during a mid-term election year. While most
of the widely recognized risks we have outlined may already be "priced into" the
market, we believe investors should continue to expect market volatility.

At Pioneer, we have long advocated the benefits of staying diversified and
investing for the long term. And while diversification does not assure a profit
or protect against loss in a declining market, we believe there are still
opportunities for prudent investors to earn attractive returns. Our advice, as
always, is to work closely with a trusted financial advisor to discuss your
goals and work together to develop an investment strategy that meets your
individual needs, keeping in mind that there is no single best strategy that
works for every investor.

Portfolio Management Discussion | 4/30/14

In the following interview, John Carey, Executive Vice President and Head of
U.S. Core Value at Pioneer Investments, discusses the investment environment
during the six-month period ended April 30, 2014, and Pioneer Equity Income
Fund's performance during the period. Mr. Carey is responsible for the
day-to-day management of Pioneer Equity Income Fund.

Q    How would you describe the market for equities during the six-month period
     ended April 30, 2014, particularly for the types of equities deemed
     appropriate for the Fund?

A    Putting the charts of the Standard & Poor's 500 (the S&P 500) and the
     Fund's benchmark, Russell 1000 Value Index (the Russell Index) on top of
     one another and holding them up to the light, one sees an almost identical
     pattern develop during the six-month period. The indices continued their
     very strong 2013 performance right down through the end of the calendar
     year, but as soon as the new year of 2014 began, the indices stopped
     advancing, treaded water for a couple of weeks, and then took a sharp
     plunge into early February. After that, the stock market as measured by
     those indices staged a strong recovery. By the end of the period the S&P
     500 and the Russell Index both showed gains for the full six months. So,
     while volatile, the market was positive during the period, and patient
     investors were able to reap rewards. Value stocks, as measured by the
     Fund's benchmark, the Russell Index (+9.61%), did on balance outperform
     growth stocks, as measured by Russell 1000 Growth Index (+6.95%), but
     bookend to bookend, the period was a good one for most stocks.

     While general economic data and corporate earnings have continued to trace
     an upward course, geopolitical events have caused the market some concerns.
     The conflict in the Ukraine, tensions between China and its neighbors, and
     continued chaos in several of the countries in the Middle East have all
     caught the attention of investors and led them to worry about potential
     disruptions to trade and to supply of certain raw materials. The prospect
     for higher interest rates as we move through 2014 and into 2015 has
     likewise remained an anxiety. And, while inflation numbers have stayed
     modest, a rise in the price of several commodities as well as increasing
     costs of services have led to a view that inflation could at some point
     ramp up. The correction we saw in the stock market during the second half
     of January 2014 resulted, we think, from those jitters, and also from
     pessimism about first calendar quarter 2014 corporate earnings due to the
     cold, snowy weather conditions in much of the U.S. over the winter months.

4 Pioneer Equity Income Fund | Semiannual Report | 4/30/14


     In the event, the "macroeconomic" risks stayed contained through the end of
     six-month reporting period, and first-quarter earnings came in meaningfully
     above expectations. So, after the sinking spell, it was off to the races
     for stocks once again. However, we would keep a weather eye and stay
     cognizant of risks.

Q    How did the Fund perform in that environment during the six-month period
     ended April 30, 2014?

A    The Fund's Class A shares returned 7.20% at net asset value during the
     six-month period ended April 30, 2014, while the Fund's benchmark, the
     Russell Index, returned 9.61%. During the same period, the average return
     of the 475 mutual funds in Lipper's Equity Income Funds category was 7.37%,
     and the average return of the 1,273 mutual funds in Morningstar's Large
     Value Funds category was 8.14%.

Q    Could you please talk in more detail about the Fund's performance during
     the six-month period ended April 30, 2014? Please discuss the
     underperformance of the Fund relative to its benchmark, the Russell Index.

A    While the Fund's absolute results were positive, they lagged relative to
     the benchmark during the period. The reason for the Fund's underperformance
     was stock selection, primarily in three sectors: industrials, energy, and
     financials. Sector allocation decisions were neutral with respect to
     performance results, with slight performance advantages deriving from the
     portfolio's overweight in the strong-performing utilities sector and an
     underweight in the below-average-performing financials sector; and slight
     performance disadvantages attributable to the portfolio's overweight to the
     below-average-performing consumer staples sector and an underweight in the
     strong-performing energy sector.

     With regard to stock selection, however, the Fund lost relative performance
     due to two of the portfolio's larger overweight positions in the
     industrials sector, Gorman-Rupp and G&K services; the Fund's very large
     underweight to Exxon Mobil, a strong performer in the energy sector; and a
     big overweight to insurer Chubb, in financials, as well as the portfolio's
     overall underweight to the above-average-performing diversified financials
     segment of the financials sector.

     After reviewing the Fund's portfolio, we elected to retain the long-term
     positions in the three underperformers noted, due to our estimates of
     continued good business prospects for all of the companies over the longer
     term. Exxon Mobil has been a harder decision, however, because we remain
     uncertain that such a large company can find ways to grow production at

                      Pioneer Equity Income Fund | Semiannual Report | 4/30/14 5


     attractive rates. Nonetheless, as we see what we believe are compelling
     buying opportunities for that and other stocks, we shall certainly consider
     adding to the Fund's positions.

Q    Could you please discuss the changes you made to the Fund's portfolio
     during the six-month period ended April 30, 2014?

A    We added eleven positions to the portfolio and eliminated eight during the
     six-month period. Additions included: Glaxo Smith Kline and Roche in
     pharmaceuticals; Randstad Holding, a temporary-help company with offices
     worldwide; Wolseley, another worldwide company, in its case a leading
     distributor of plumbing and heating supplies as well as building materials;
     Cameco, an important uranium miner; Bank of America and JPMorgan Chase in
     diversified financials; Prudential in life insurance; State Street, a
     prominent provider of services to the financial industry and also a large
     money manager; and Chesapeake Lodging Trust, a real estate investment trust
     focused, as its name suggests, on hotels. Due to the modest near-term
     valuation of the stock resulting from a prolonged period of
     underperformance, we did also add shares of Exxon Mobil to the portfolio's
     existing position, but at a level underweight to the Russell Index because
     of our aforementioned uncertainty over the company's longer-term potential.

     Sales from the portfolio during the six-month period included one big
     winner, Molex, which was acquired for cash by another company at a premium
     to the Fund's original cost. On the basis of our relative-value analysis,
     we sold Chevron and Conoco (energy) to make room for our purchase of Exxon
     Mobil. Other liquidations were of the Fund's positions in Rio Tinto, Maxim
     Integrated Products, Medtronic, Seadrill, and Bank of Montreal, in each
     case because we judged that other new or existing portfolio holdings
     represented better long-term value.

Q    The Fund typically places an emphasis on dividend-paying stocks. Would you
     describe the environment for dividends as positive or negative during the
     six-month period ended April 30, 2014?

A    Companies in the U.S. and Europe, the Fund's two principal investment
     "hunting grounds," continue to place significant emphasis on dividend*
     payments and increases in the rate of dividend payments as ways to keep
     current investors "on board" while attracting new investors. With the very
     low short-term interest rates in both the U.S. and Europe, investors
     desiring current income can potentially find worthwhile income-generating
     opportunities in the stock market. Secondly, with the still moderate rate
     of capital spending and high levels of profit generation, a lot of
     companies are

* Dividends are not guaranteed.

     finding themselves with cash that they feel they do not need for their
     day-to-day operations, and they are both paying higher dividends and
     repurchasing their own stock in order to reduce their cash balances. A note
     of caution, though: with capacity utilization nudging higher and higher and
     worker productivity no longer increasing, many companies may find that they
     do, afterall, have to spend more money on new plant and equipment.
     Strategic mergers and acquisitions in a growing, but historically
     relatively slowly growing, economy may also make more and more sense to
     companies. Hence, other uses for excess cash may lead to lower rates of
     dividend growth as we continue moving through this business cycle.

Q    With the Federal Reserve's (Fed's) tapering of its QE (quantitative easing)
     program underway and the harsh winter of 2013-14 behind us, what is your
     outlook on the U.S economy and the equity markets for the remainder of the
     Fund's fiscal year ending October 31, 2014?

A    Intermediate and longer-term interest rates had actually come down a bit by
     the end of the Fund's April 30, 2014, semiannual reporting period. The bond
     market reflected an apparent investor view that too much pessimism about
     interest rates had come into that market after the Fed's initial talk of QE
     tapering in May 2013. There has just not been the inflation, the borrowing
     demand, or the rate of economic growth that would naturally push rates
     higher, and so even with the Fed's tapering, investors have come back into
     bonds. As we noted previously, we would be wary of complacency in regard to
     inflation in particular, and we would not view the current, almost ideal
     conditions for borrowers, almost no matter what their capacity for
     repayment, as a permanent state of affairs. Time will tell. Otherwise, in
     regard to stocks, we are also of the mind that investors have become
     complacent about the ability of companies to maintain their current, high
     profit margins, especially without an increase in worker productivity.

     Our approach, as always, is to favor companies we believe have strong
     balance sheets, astute and committed managements, industry-leading
     positions, positive long-term earnings trends, and attractive valuations.
     In this time of possibly significant geopolitical risks we are also
     steering away from investing the Fund in companies that are unusually
     exposed to one or another of the world's potential flash points. It is our
     intention to keep the Fund's portfolio broadly diversified** and invested
     in companies with experience in working through challenging times and
     conditions.

     Thank you very much for your support.

**   Diversification does not assure a profit nor protect against loss in a
     declining market.

Investing in foreign and/or emerging markets securities involves risks relating
to interest rates, currency exchange rates, economic, and political conditions.

The portfolio invests in REIT securities, the value of which can fall for a
variety of reasons, such as declines in rental income, fluctuating interest
rates, poor property management, environmental liabilities, uninsured damage,
increased competition, or changes in real estate tax laws.

At times, the Fund's investments may represent industries or industry sectors
that are interrelated or have common risks, making it more susceptible to any
economic, political, or regulatory developments or other risks affecting those
industries and sectors.

These risks may increase share price volatility.

The Russell 1000 Value Index is an unmanaged index that 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. 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 11-17.

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.

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.

The performance shown for Class K shares for the period prior to the
commencement of operations of Class K shares on December 20, 2012, is the net
asset value performance of the Fund's Class A shares, which has not been
restated to reflect any differences in expenses, including Rule 12b-1 fees
applicable to Class A shares. Since fees for Class A shares generally are higher
than those of Class K shares, the performance of Class K shares prior to their
inception on December 20, 2012, would have been higher than the performance
shown. For the period beginning December 20, 2012, the actual performance of
Class K shares is reflected. Class K 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.

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.

Performance shown for Class Z shares for periods prior to the inception of Class
Z shares on July 6, 2007, is the net asset value 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 for Class Z
shares prior to their inception on July 6, 2007, would have been higher than the
performance shown. For the period beginning July 6, 2007, the actual performance
of Class Z shares is reflected. 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

Comparing Ongoing Fund Expenses

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

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

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

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

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

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

(1) Divide your account value by $1,000
    Example: an $8,600 account value (divided by) $1,000 = 8.6

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

Hypothetical Example for Comparison Purposes

The table below provides information about hypothetical account values and
hypothetical expenses based on the Fund's actual expense ratio and an assumed
rate of return of 5% per year before expenses, which is not the Fund's actual
return. The hypothetical account values and expenses may not be used to estimate
the actual ending account balance or expenses you paid for the period.

You may use this information to compare the ongoing costs of investing in the
Fund and other funds. To do so, compare this 5% hypothetical example with the 5%
hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the tables are meant to highlight your
ongoing costs only and do not reflect any transaction costs, such as sales
charges (loads) that are charged at the time of the transaction. Therefore, the
table below is useful in comparing ongoing costs only and will not help you
determine the relative total costs of owning different funds. In addition, if
these transaction costs were included, your costs would have been higher.

Purchases and sales of securities (excluding temporary cash investments) for the
six months ended April 30, 2014 aggregated $158,162,700 and $179,210,710,
respectively.

Various inputs are used in determining the value of the Fund's investments.
These inputs are summarized in the three broad levels listed below.

    Level 1 -- quoted prices in active markets for identical securities.

    Level 2 -- other significant observable inputs (including quoted prices for
               similar securities, interest rates, prepayment speeds, credit
               risk, etc.) See Notes to Financial Statements -- Note 1A.

    Level 3 -- significant unobservable inputs (including the Fund's own
               assumptions in determining fair value of investments) See Notes
               to Financial Statements -- Note 1A.

Generally, equity securities are categorized as Level 1, fixed income securities
and senior loans as Level 2 and securities valued using fair value methods
(other than prices supplied by independent pricing services or broker-dealers)
as Level 3. See Notes to Financial Statements -- Note 1A.

The following is a summary of the inputs used as of April 30, 2014, in valuing
the Fund's investments:

1. Organization and Significant Accounting Policies

Pioneer Equity Income Fund (the Fund) is a Delaware statutory trust. The Fund is
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 seven classes of shares designated as Class A, Class B, Class C,
Class K, Class R, Class Y and Class Z shares. Class K shares were first publicly
offered on December 20, 2012. 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 K, Class Y or Class Z shares. Class B shares convert
to Class A shares approximately eight years after the date of purchase.

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

38 Pioneer Equity Income Fund | Semiannual Report | 4/30/14


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. Short-term fixed income
     securities with remaining maturities of sixty days or less generally are
     valued at amortized cost. Shares of money market mutual funds are valued at
     such funds' net asset value.

     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.

     Securities for which independent pricing services are unable to supply
     prices or for which market prices and/or quotations are not readily
     available or are considered to be unreliable are valued by a fair valuation
     team comprised of certain personnel of Pioneer Investment Management, Inc.,
     (PIM), the Fund's investment adviser, pursuant to procedures adopted by the
     Fund's Board of Trustees. PIM's fair valuation team uses fair value methods
     approved by the Valuation Committee of the Board of Trustees. PIM's fair
     valuation team is responsible for monitoring developments that may impact
     fair valued securities and for discussing and assessing fair values on an
     ongoing basis, and at least quarterly, with the Valuation Committee of the
     Board of Trustees.

     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. 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. Examples of a significant
     event might include political or economic news, corporate restructurings,
     natural disasters, terrorist activity or trading halts. Thus, the valuation
     of the Fund's securities may differ significantly from exchange prices and
     such differences could be material.

     At April 30, 2014, there were no securities that were valued using fair
     value methods (other than securities that were valued using prices supplied
     by independent pricing services or broker-dealers).

                     Pioneer Equity Income Fund | Semiannual Report | 4/30/14 39


     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, including
     interest on income bearing cash accounts, is recorded on the accrual basis.
     Dividend and interest income are reported net of unrecoverable foreign
     taxes withheld at the applicable country rates.

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

B.   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. As of
     April 30, 2014, the Fund did not accrue any interest or penalties with
     respect to unrecognized tax positions, which, if applicable, would be
     recorded as an income tax expense in the Statement of Operations. Tax
     returns filed within the prior three years are subject to examination by
     Federal and State tax authorities.

     The amount and character of income and capital gain distributions to
     shareowners are determined in accordance with federal income tax rules,
     which may differ from U.S. generally accepted accounting principles.
     Distributions in excess of net investment income or net realized gains are
     temporary overdistributions for financial statement purposes resulting from
     differences in the recognition or classification of income or distributions
     for financial statement and tax purposes. Capital accounts within the
     financial statements are adjusted for permanent book/tax differences to
     reflect tax character, but are not adjusted for temporary differences.

     The tax character of current year distributions payable will be determined
     at the end of the current taxable year. The tax character of distributions
     paid during the year ended October 31, 2013 was as follows:

        Total                                                        $38,451,454

     The following shows the components of distributable earnings on a federal
     income tax basis at October 31, 2013:



     ---------------------------------------------------------------------------
                                                                            2013
     ---------------------------------------------------------------------------
                                                                 
     Distributable earnings:
     Undistributed ordinary income                                  $  2,669,324
     Undistributed long term capital gain                             49,276,208
     Net unrealized appreciation                                     439,102,090
     ---------------------------------------------------------------------------
         Total                                                      $491,047,622
     ===========================================================================


     The difference between book-basis and tax-basis net unrealized appreciation
     is attributable to the tax deferral of losses on wash sales and tax basis
     adjustments on Real Estate Investment Trust (REIT) holdings and
     partnerships.

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 S.p.A.
     (UniCredit), earned $47,069 in underwriting commissions on the sale of
     Class A shares during the six months ended April 30, 2014.

D.   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, Class C and Class R shares of the Fund,
     respectively (see Note 4). Class K, Class Y and Class Z 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, Class K, Class R,
     Class Y and Class Z shares can reflect different transfer agent and
     distribution expense rates.

E.   Risks

     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 or 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.

F.   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 appreciation or depreciation
     is recorded in the Fund's financial statements. The Fund records realized
     gains and losses at the time a contracts 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 8).

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. PIM is responsible for determining that the value of the collateral
     remains at least equal to the repurchase price.

2. Management Agreement

PIM, a wholly owned indirect subsidiary of UniCredit, manages the Fund's
portfolio. Management fees are calculated daily at the annual rate of 0.60% of
the Fund's average daily net assets up to $10 billion and 0.575% on assets over
$10 billion. For the six months ended April 30, 2014, the effective management
fee (excluding waivers and/or assumption of expenses) was equivalent to 0.60% 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
$64,319, in management fees, administrative costs and certain other
reimbursements payable to PIM at April 30, 2014.

3. Transfer Agent

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

In addition, the Fund reimburses PIMSS for out-of-pocket expenses incurred by
PIMSS related to shareholder communications activities such as proxy and
statement mailings, outgoing phone calls and omnibus relationship contracts.

For the six months ended April 30, 2014, such out-of-pocket expenses by class of
shares were as follows:

Class A                                                                 $434,676
Class B                                                                    7,060
Class C                                                                   50,653
Class K                                                                        7
Class R                                                                  104,162

   Total                                                                $918,578
================================================================================


Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $392,736 in transfer agent fees and out-of-pocket reimbursements
payable to PIMSS at April 30, 2014.

4. Distribution and Service Plans

The Fund has adopted a Distribution Plan pursuant to Rule 12b-1 of the
Investment Company Act of 1940 with respect to its Class A, Class B, Class C and
Class R 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. Pursuant to the Plan, the Fund further pays PFD 0.50% of the average
daily net assets attributable to Class R shares for distribution services.
Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $24,415 in distribution fees payable to PFD at April 30, 2014.

The Fund also has adopted a separate service plan for Class R shares (Service
Plan). The Service Plan authorizes the Fund to pay securities dealers, plan
administrators or other service organizations that agree to provide certain

                     Pioneer Equity Income Fund | Semiannual Report | 4/30/14 43


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 addition, redemptions of each class of shares (except Class K, Class R, Class
Y and Class Z 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
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 12 months 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 K, Class R, Class Y or Class Z shares. Proceeds from the CDSCs are paid to
PFD. For the six months ended April 30, 2014, CDSCs in the amount of $6,653 were
paid to PFD.

5. Expense Offset Arrangements

The Fund has entered into certain expense offset arrangements with PIMSS which
may result 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, 2014, 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 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. The
credit facility until February 12, 2014 was in the amount of $215 million. As of
February 12, 2014 the facility is in the amount of $240 million. Under such
facility, depending on the type of loan, interest on borrowings is payable at
the London Interbank Offered Rate (LIBOR) plus 0.90% (0.85% as of February 12,
2014) on an annualized basis, or the Alternate Base Rate, which is the greater
of (a) the facility's administrative agent's daily announced prime rate on the
borrowing date, (b) 2% plus the Federal Funds Rate on the borrowing date and (c)
2% plus the overnight Euro dollar rate on the borrowing date. The Funds pay an
annual commitment fee to participate in the credit facility. The commitment fee
is allocated among participating Funds based on an allocation schedule set forth
in the credit agreement. For the six months ended April 30, 2014, the Fund had
no borrowings under the credit facility.

7. Affiliated Companies

The Fund's investments in certain companies may exceed 5% of the outstanding
voting stock of those companies. Such companies are deemed affiliates of the
Fund for financial reporting purposes. The following summarizes transactions

8. Forward Foreign Currency Contracts

During the six months ended April 30, 2014, 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. During the six
months ended April 30, 2014, the Fund held no forward foreign currency
contracts.

9. Subsequent Event

Change in Independent Registered Public Accounting Firm

The board of Trustees of the Fund, with the approval and recommendation of the
Audit Committee, appointed Deloitte & Touche LLP to serve as the Fund's
independent registered public accounting firm for the fiscal year ending October
31, 2014. Deloitte & Touche LLP replaces Ernst & Young LLP, which resigned as
the Fund's independent registered public accounting firm, effective upon
completion of the audit of the Fund's financial statements for the fiscal year
ended October 31, 2013.

During the periods that Ernst & Young LLP served as the Fund's independent
registered public accounting firm, including the Fund's two most recent fiscal
year, Ernst & Young LLP's reports on the financial statements of the Fund have
not contained an adverse opinion or disclaimer of opinion and have not been
qualified or modified as to uncertainty, audit scope or accounting principles or
practices, financial statement disclosure, or auditing scope or procedure,
which, if not resolved to the satisfaction of Ernst & Young LLP would have
caused Ernst & Young LLP to make reference to the subject matter of the
disagreement in connection with its report on the financial statements. In
addition, there have been no reportable events to the kind described in Item
304(a)(i)(v) of Regulation S-K under the Securities and Exchange Act of 1934.

Approval of Investment Advisory Agreement

Pioneer Investment Management, Inc. (PIM) serves as the investment adviser to
Pioneer Equity Income Fund (the Fund) pursuant to an investment advisory
agreement between PIM and the Fund. In order for PIM to remain the investment
adviser of the Fund, the Trustees of the Fund must determine annually whether to
renew the investment advisory agreement for the Fund.

The contract review process began in March 2013 as the Trustees of the Fund
agreed on, among other things, an overall approach and timeline for the process.
In July 2013, the Trustees approved the format of the contract review materials
and submitted their formal request to PIM to furnish information necessary to
evaluate the terms of the investment advisory agreement. The contract review
materials were provided to the Trustees in July 2013 and September 2013. After
reviewing and discussing the materials, the Trustees submitted a request for
additional information to PIM, and materials were provided in response to this
request. Meetings of the Independent Trustees of the Fund were held in July,
September, and November, 2013 to review and discuss the contract review
materials. In addition, the Trustees took into account the information related
to the Fund provided to the Trustees at regularly scheduled meetings.

At a meeting held on November 12, 2013, based on their evaluation of the
information provided by PIM and third parties, the Trustees of the Fund,
including the Independent Trustees voting separately, unanimously approved the
renewal of the investment advisory agreement for another year. In considering
the renewal of the investment advisory agreement, the Trustees considered
various factors that they determined were relevant, including the factors
described below. 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 did not identify any single
factor as the controlling factor in determining to approve the renewal of the
agreement.

Nature, Extent and Quality of Services

The Trustees considered the nature, extent and quality of the services that had
been provided by PIM to the Fund, taking into account the investment objective
and strategy of the Fund. 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 reviewed the amount of non-Fund assets managed by the portfolio
managers of the Fund. The Trustees considered the non-investment resources and
personnel of PIM involved in

46 Pioneer Equity Income Fund | Semiannual Report | 4/30/14


PIM's services to the Fund, including PIM's compliance and legal resources and
personnel. The Trustees noted the substantial attention and high priority given
by PIM's senior management to the Pioneer fund complex.

The Trustees considered that PIM supervises and monitors the performance of the
Fund's service providers and provides the Fund with personnel (including Fund
officers) and other resources that are necessary for the Fund's business
management and operations. The Trustees also considered that, as administrator,
PIM is responsible for the administration of the Fund's business and other
affairs. The Trustees considered the fees paid to PIM for the provision of
administration services.

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

Performance of the Fund

The Trustees review the Fund's performance on a regular basis, based on analysis
and data prepared by PIM for this purpose and discuss performance issues with
PIM on an ongoing basis. For purposes of their contract renewal deliberations,
the Trustees considered the performance results of the Fund over various time
periods. They reviewed information comparing the Fund's performance with the
performance of its peer group of funds as classified by Morningstar, Inc.
(Morningstar), an independent provider of investment company data, and with the
performance of the Fund's benchmark index. The Trustees considered that the
Fund's annualized total return was in the fourth quintile of its Morningstar
category for the one year period ended June 30, 2013, in the second quintile of
its Morningstar category for the three and ten year periods ended June 30, 2013,
and in the third quintile of its Morningstar category for the five year period
ended June 30, 2013. The Trustees also considered that the Fund's yield (for the
twelve months ended June 30, 2013) exceeded the yield of the Fund's benchmark
index for the same period. The Trustees noted the discussions held throughout
the year regarding the Fund's performance and confirmed that those discussions
were factored into the Trustees' deliberations concerning the renewal of the
advisory agreement. The Trustees considered reasons for the underperformance of
the Fund relative to its peer group and the steps recently taken in an effort to
improve the performance of the Fund. The Trustees agreed that they would
continue to closely monitor the Fund's performance.

Management Fee and Expenses

The Trustees considered information showing the fees and expenses of the Fund in
comparison to the management fees and expense ratios of its peer group of funds
as classified by Morningstar and also to the expense ratios of a peer group of
funds selected on the basis of criteria determined by the

                     Pioneer Equity Income Fund | Semiannual Report | 4/30/14 47


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, 2013 was in the second quintile relative to the management fees
paid by other funds in its Morningstar peer group for the comparable period. The
Trustees also considered the breakpoint in the management fee schedule and the
reduced fee rate above a certain asset level. The Trustees considered that the
Fund's expense ratio for the twelve months ended June 30, 2013 was in the third
quintile relative to both its Morningstar peer group and its Strategic Insight
peer group, in each case for the comparable period.

The Trustees reviewed management fees charged by PIM and PIM's affiliate,
Pioneer Institutional Asset Management, Inc. (together with PIM, "Pioneer") to
institutional and other clients, including publicly offered European funds
sponsored by affiliates of Pioneer, unaffiliated U.S. registered investment
companies (in a sub-advisory capacity), and unaffiliated foreign and domestic
separate accounts. The Trustees also considered PIM's costs in providing
services to the Fund and Pioneer's costs in providing services to the other
clients and considered the differences in management fees and profit margins for
Fund and non-Fund services. In evaluating the fees associated with Pioneer's
client accounts, the Trustees took into account the respective demands,
resources and complexity associated with the Fund and client accounts. The
Trustees noted that, in some instances, the fee rates for those clients were
lower than the management fee 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 or services that
are broader in scope, including oversight of the Fund's other service providers
and activities related to compliance and the extensive regulatory and tax
regimes to which the Fund is subject. The Trustees also considered the different
entrepreneurial risks associated with PIM's management of the Fund and Pioneer's
management of the other client accounts. The Trustees concluded that the
management fee payable by the Fund to PIM was reasonable in relation to the
nature and quality of the services provided by PIM.

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

48 Pioneer Equity Income Fund | Semiannual Report | 4/30/14


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 concluded that PIM's profitability with respect to the management of
the Fund was not unreasonable.

Economies of Scale

The Trustees considered PIM's views relating to economies of scale in connection
with the Pioneer Funds as fund assets grow and the extent to which any such
economies of scale are shared with funds and fund shareholders. The Trustees
noted the breakpoint in the management fee schedule. The Trustees recognize that
economies of scale are difficult to identify and quantify, rarely identifiable
on a fund-by-fund basis, and that, among other factors that may be relevant, are
the following: fee levels, expense subsidization, investment by PIM in research
and analytical capabilities and PIM's commitment and resource allocation to the
Fund. The Trustees noted that profitability also may be an indicator of the
availability of any economies of scale, although profitability may vary for
other reasons particularly, for example during the recent difficult periods for
financial markets, as the level of services was maintained notwithstanding a
significant decline in PIM's fee revenues from the Fund. Accordingly, the
Trustees concluded that economies of scale, if any, were being appropriately
shared with the Fund.

Other Benefits

The Trustees considered the other benefits to PIM from its relationship with the
Fund. The Trustees considered the character and amount of fees paid by the Fund,
other than under the investment advisory agreement, for services provided by PIM
and its affiliates. The Trustees further considered the revenues and
profitability of PIM's businesses other than the fund business. The Trustees
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
investment advisory agreement between PIM and the Fund, including the fees
payable thereunder, was fair and reasonable and voted to approve the proposed
renewal 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.

                 not performed by the Audit
                 firm, the scope of the Audit
                 Services would likely
                 increase.  The Services are
