President's Letter

Dear Shareowner,

At mid-year, economic conditions and government policies around the world are
far from homogeneous, and we expect them to continue to diverge. In the United
States, an ongoing economic expansion has brought the unemployment rate down to
levels where wage growth is likely to accelerate. Economic growth and fiscal
austerity have dramatically reduced the Federal budget deficit, while very
accommodative Federal Reserve System policies have kept interest rates
exceptionally low. In Europe and Japan, cyclical economic recoveries/expansions
appear to be gaining traction, buttressed by aggressive quantitative easing
policies of central banks as well as cheaper currencies. China's ongoing
transition from an infrastructure investment-driven to a consumer-driven economy
and the dramatic decline in the price of oil -- largely a result of U.S.
"fracking" -- have benefited some countries while burdening others. On balance,
though, the global economic outlook has continued to improve, although economic
and geopolitical "storm clouds" remain.

Today's market environment presents numerous opportunities as well as challenges
for investors. While we believe that the capital markets may already have priced
in some recent trends, such as the U.S. dollar's appreciation against a basket
of global currencies, it is worth noting that investment risks and opportunities
are not always aligned with the economic outlook.

Since 1928, Pioneer's investment professionals have focused on identifying and
capitalizing on the investment opportunities that present themselves in a
variety of ever-changing economic and market conditions, including those we face
today, while seeking to limit the risk of the permanent impairment of our
clients' capital. Our ongoing goal is to deliver competitive returns consistent
with our strategies' stated style and objectives and consistent with our
shareholders' expectations over a range of market conditions. We believe our
shareowners benefit from the experience and tenure of our investment teams, the
insights generated from extensive research resources, and our commitment to
prudent risk management.

investment plan that addresses both your short- and long-term goals, and to

continuing to serve you in the future.

Sincerely,

/s/ Lisa M. Jones

Portfolio Management Discussion | 4/30/15

In the following interview, John Carey, Executive Vice President and Director of
U.S. Portfolio Management at Pioneer Investments, discusses the investment
environment during the six-month period ended April 30, 2015, 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, 2015, particularly for the types of equities deemed
     appropriate for the Fund?

A    The stock market was quite choppy during the six-month period. As measured
     by the Standard & Poor's 500 Index (+4.39%) and the Fund's benchmark, the
     Russell 1000 Value Index (+2.89%), stocks went up and down at frequent
     intervals, ending the period with a modest total return. Throughout the
     period, investors, heeding signals from the Federal Reserve System (the
     Fed), were nervous about the prospect of higher interest rates. The sharp
     drop in the price of oil that continued during much of the period also
     created anxiety, as opinions were mixed as to whether the decline was the
     consequence of greater production, particularly from shale fields in the
     United States, or was rather the result of slowing demand in a cooling
     global economy. Then, too, daily stories of geopolitical issues ranging
     from the Middle East, Africa, the Ukraine, and the Korean peninsula
     reminded investors of the ever-present and largely imponderable risks
     arising from international tension and instability. Greece and its
     financial woes also kept investors on edge about prospects for the euro
     region; and Brazil, Venezuela, and Argentina and their faltering economies
     diminished investors' hopes for the emerging markets.

     For value-oriented, dividend-paying stocks*, which are the focus of Pioneer
     Equity Income Fund, the period saw a waxing and waning of investor
     interest. In particular, the ever-present potential for the Fed to raise
     interest rates made investors skittish about cyclical stocks as well as
     utilities. During the six-month period, the Russell 1000 Growth Index, with
     a total return of 6.54%, significantly outperformed the Russell 1000 Value
     Index, which returned 2.89%. In a world economy that was sending mixed
     signals about the sustainability of earnings growth, investors favored
     companies appearing able to achieve earnings growth, regardless. Hence,
     stocks in the biotechnology and information-technology industries, in
     particular, attracted attention, and some with particular promise did
     especially well

*    Dividends are not guaranteed.

     over the period. Nonetheless, certain stocks in other industries also
     performed positively when investors perceived their prices to be supported
     by stable earnings and dividends.

Q    How did the Fund perform in that environment during the six-month period
     ended April 30, 2015?

A    Pioneer Equity Income Fund's Class A shares returned 4.16% at net asset
     value during the six-month period ended April 30, 2015, while the Fund's
     benchmark, the Russell 1000 Value Index (the Russell Index), returned
     2.89%. During the same period, the average return of the 514 mutual funds
     in Lipper's Equity Income Funds category was 2.96%, and the average return
     of the 1,391 mutual funds in Morningstar's Large Value Funds category was
     3.24%.

Q    The Fund outperformed the Russell Index during the six-month period ended
     April 30, 2015. Could you please discuss the most significant reasons for
     the Fund's benchmark-relative outperformance?

A    The Fund's strong benchmark-relative performance resulted from a
     combination of favorable sector allocation decisions and successful stock
     selection results. Energy was the worst-performing sector in the Russell
     Index during the period, and the Fund was both quite underweight the sector
     as well as invested in energy stocks that performed better than the sector
     average. The Fund's underweights to ExxonMobil and Chevron were especially
     contributory to the Fund's benchmark-relative performance during the
     period.

     The drop in the price of oil, so hurtful to results in the energy sector,
     was helpful to results in consumer discretionary, as investors figured that
     consumers would spend their savings at the gas pump on everything from
     clothes to entertainment to household appliances. The Fund was overweight
     consumer discretionary and invested in stocks in the sector that performed
     better than the sector average. A position in Cedar Fair was a big winner
     for the portfolio in the sector. Also benefiting the Fund's performance was
     a premium acquisition offer made for Kraft Foods, a company in the consumer
     staples sector. Meanwhile, in information technology, the Fund's position
     in Microchip Technology contributed positively to benchmark-relative
     returns.

     On the negative side, the Fund's overweight to the underperforming
     utilities sector detracted from benchmark-relative performance, as did
     stock selections in financials, industrials, and health care. A position in
     Canadian Imperial Bank of Commerce, which was dragged down by concerns that
     the energy slump would restrain economic growth in natural-resources-heavy

                    Pioneer Equity Income Fund | Semiannual Report | 4/30/15   5


     Canada, was a notable underperformer for the Fund in financials. In
     industrials, the portfolio's holdings of Gorman-Rupp, MSA Safety, and
     Canadian National Railway all declined in share price while the Industrials
     sector as a whole actually showed an above-average gain. And in health
     care, the Fund's underweights to strong performers Pfizer and UnitedHealth
     Group were the main causes of underperformance in the sector.

Q    Could you highlight some of the changes you made to the Fund's portfolio
     during the six-month period ended April 30, 2015?

A    The Fund added nine positions and eliminated 12 during the six-month
     period. In financials, we added American Express, Citizens Financial,
     JPMorgan Chase, and Progressive, while eliminating PNC Financial Services,
     Prudential Financial, and the aforementioned Canadian Imperial Bank of
     Commerce. In the cases of American Express and Citizens Financial, in
     particular, but also JPMorgan Chase and Progressive, we saw prospects for
     improvement from the companies' current earnings levels. With respect to
     purchases of Broadcom and International Business Machines (IBM) in
     information technology, BHP Billiton in materials, Kohls in consumer
     discretionary, and Raytheon in industrials, we similarly estimated earnings
     potential ahead of what the companies' share prices appeared to reflect.

     Sales during the period included positions we thought had reached
     reasonable value, for example American Water Works, PNC Financial Services,
     and Hewlett-Packard; other positions where we felt prospects had become
     less certain, such as Coca-Cola Enterprises, CSX, and Macy's; and, finally,
     stocks we just thought had less-compelling prospects than names we wished
     to purchase.

Q    Did the Fund hold any derivatives during the six-month period ended April
     30, 2015?

A    No. The Fund had no investments in derivatives during the period.

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, 2015?

A    On the whole, dividend-paying stocks continue to find investors in a
     low-interest-rate environment. However, the Fed has indicated its intent to
     raise interest rates, and that has made investors more cautious about
     stocks that derive a major part of their attractiveness from the dividends
     they pay rather than high earnings growth. Utilities and REITs (real estate
     investment trusts) have come under occasional pressure when investors have
     felt interest-rate increases might be coming sooner rather

6 Pioneer Equity Income Fund | Semiannual Report | 4/30/15


     than later. The fact is, though, that as we write this letter, the Fed has
     still not acted, and commentators are quite mixed in their views as to when
     exactly the Fed will act. We would note that most estimates are for rather
     modest increases in interest rates if and when they do come. Our own view
     is that dividends on many stocks, and the potential growth in dividends,
     may permit dividend-paying stocks to continue competing with other asset
     classes in a moderately-rising interest-rate environment.

Q    What is your outlook for the equity markets as we approach the middle of
     2015?

A    The stock market often sees rotation between sectors and industries with
     different valuation and earnings characteristics. While growth stocks did
     better than value stocks during the six-month period ended April 30, 2015,
     there have been many other periods in the history of the U.S. stock market
     when value has done better than growth. So-called macroeconomic factors,
     such as currency exchange rates, commodities prices, inventory levels,
     capacity utilization, employment levels, and interest rates, can push
     corporate results around and affect the behavior of equity investors. There
     can also be reactions among investors to news of political upheavals and
     war, as well as natural disasters.

     Most important to watch, we have always thought, is the level of earnings
     companies are able to achieve. Right now, we are cautious on the outlook
     for earnings, primarily because consumer spending, the most important
     contributor to the U.S. economy, has at least temporarily slowed, despite
     lower gasoline prices. We also note many economic issues in foreign
     economies and the issues' adverse effects on earnings of the U.S.
     multinational companies. At the same time, equity valuations as measured by
     price-to-earnings multiples are somewhat above their long-term averages,
     suggesting that many stocks are at least fairly valued if not expensive.

     While we are, then, cautious for the near term, we think, as always, that a
     longer-term expectation can still be quite positive. We meet almost every
     day with the managements of companies whose stocks we hold in one or
     another of our portfolios here at Pioneer, and we hear many of those
     managements describe exciting business opportunities. The key of course is
     to buy shares with potential for total return over time, and the task for
     us is to do careful analysis of the expectations built into the prices of
     shares. Our objective is to manage the portfolio in a way that takes into
     account both risks and opportunities.

     Thank you for your support.

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 11-16.

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.

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 19, 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 19, 2012, would have been higher than the performance
shown. For the period beginning December 19, 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

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.

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
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.

that a shareowner would pay on Fund distributions or the redemption of Fund
shares.

Comparing Ongoing Fund Expenses

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

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

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

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

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

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

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

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

     R, Class Y and Class Z shares, respectively, multiplied by the average
     account value over the period multiplied by 181/365 (to reflect the
     one-half year period).

Hypothetical Example for Comparison Purposes

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

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

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

Purchases and sales of securities (excluding temporary cash investments) for the
six months ended April 30, 2015 aggregated $153,844,855 and $212,985,951,
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.

The following is a summary of the inputs used as of April 30, 2015, 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.

During the period covered by this report, the Fund offered six classes of shares
designated as Class A, Class C, Class K, Class R, Class Y and Class Z shares.
Class K shares commenced operations on December 20, 2012. The Fund ceased to
offer Class B shares on November 10, 2014. Class B shares were converted to
Class A shares as of the close of business on November 10, 2014. 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.

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:

36 Pioneer Equity Income Fund | Semiannual Report | 4/30/15


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. 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, 2015, 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 | 4/30/15 37


B.   Investment Income and Transactions

     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.

C.   Federal Income Taxes

     It is the Fund's policy to comply with the requirements of the Internal
     Revenue Code applicable to regulated investment companies and to distribute
     all of its taxable income and net realized capital gains, if any, to its
     shareowners. Therefore, no federal income tax provision is required. As of
     October 31, 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
     during the year ended October 31, 2014 was as follows:

                                                                                    2014
     -----------------------------------------------------------------------------------
                                                                         
     Distributable earnings:
     Undistributed ordinary income                                          $  5,889,102
     Undistributed long term capital gain                                    128,312,572
     Net unrealized appreciation                                             448,397,070

        Total                                                               $582,598,744
     ===================================================================================


     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.

D.   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 $45,465 in underwriting commissions on the sale of
     Class A shares during the six months ended April 30, 2015.

E.   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 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 C, Class K, Class R, Class Y
     and Class Z shares can reflect different transfer agent and distribution
     expense rates.

F.   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.

G.   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 contract 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).

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, 2015, 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
$52,332, in management fees, administrative costs and certain other
reimbursements payable to PIM at April 30, 2015.

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.

Liabilities is $372,383 in transfer agent fees and out-of-pocket reimbursements

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 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 C shares. The fee for 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 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 $19,238 in distribution
fees payable to PFD at April 30, 2015.

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
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. 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

                     Pioneer Equity Income Fund | Semiannual Report | 4/30/15 41


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, 2015, CDSCs in the amount of $2,452 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, 2015, 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 in effect during the six months ended April 30, 2015 was in the
amount of $215 million. Under such facility, depending on the type of loan,
interest on borrowings is payable at the London Interbank Offered Rate
(LIBOR) plus 0.85% (0.90% prior to 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, 2015, 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

10. 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 replaced 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 fiscal years ended
October 31, 2013 and October 31, 2012, 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. Further, there have been no disagreements
with Ernst & Young LLP on any matter of 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 of the kind described in Item 304 (a)(1)(v) of
Regulation S-K under the Securities Exchange Act of 1934.

11. Conversion of Class B Shares

As of the close of business on November 10, 2014 (the "Conversion Date"), all
outstanding Class B shares of the Fund were converted to Class A shares.

12. Subsequent Event

As of the close of business on August 7, 2015 (the "Conversion Date"), all
outstanding Class Z shares of the Fund will be converted to Class Y shares.
Shareholders may continue to hold their Class Z shares until the Conversion. No
sales charges or other charges will be assessed in connection with the
Conversion.

ADDITIONAL INFORMATION

PIM, the Fund's investment adviser, is currently an indirect, wholly-owned
subsidiary of UniCredit. On April 23, 2015, UniCredit announced that it
signed a preliminary and exclusive agreement with Banco Santander and
affiliates of Warburg Pincus and General Atlantic (the "Private Equity Firms")
with respect to Pioneer Investments ("Pioneer") and Santander Asset
Management ("SAM") (the "Transaction").

Pursuant to the preliminary agreement, the Transaction will entail the
establishment of a holding company, with the name Pioneer Investments, to be
owned by UniCredit (50%) and the Private Equity Firms (50% between them).
The holding company will control Pioneer's U.S. operations, including the
Adviser. The holding company also will own 66.7% of Pioneer's and SAM's
combined operations outside the U.S., while Banco Santander will own directly
the remaining 33.3% stake. The completion of the Transaction is subject to the
signing of a definitive agreement, as well as certain regulatory and corporate
approvals, and other conditions.

Under the Investment Company Act of 1940, completion of the Transaction
will cause the Fund's investment advisory agreement with the Adviser to
terminate. In connection with the Transaction, the Fund's Board of Trustees
will be asked to approve a new investment advisory agreement for the Fund. If
approved by the Board, the Fund's new investment advisory agreement will be
submitted to the shareholders of the Fund for their approval.

(a) Disclose whether, as of the end of the period covered by the report, the
registrant has adopted a code of ethics that applies to the registrant's
principal executive officer, principal financial officer, principal accounting
officer or controller, or persons performing similar functions, regardless of
whether these individuals are employed by the registrant or a third party.  If
the registrant has not adopted such a code of ethics, explain why it has not
done so.

The registrant has adopted, as of the end of the period covered by this report,
a code of ethics that applies to the registrant's principal executive officer,
principal financial officer, principal accounting officer and controller.

(b) For purposes of this Item, the term "code of ethics" means written standards
that are reasonably designed to deter wrongdoing and to promote:

        (1) Honest and ethical conduct, including the ethical handling of actual
        or apparent conflicts of interest between personal and professional
        relationships;

        (2) Full, fair, accurate, timely, and understandable disclosure in
        reports and documents that a registrant files with, or submits to, the

        (3) Compliance with applicable governmental laws, rules, and

        (5) Accountability for adherence to the code.

(c) The registrant must briefly describe the nature of any amendment, during the
period covered by the report, to a provision of its code of ethics that applies
to the registrant's principal executive officer, principal financial officer,
principal accounting officer or controller, or persons performing similar
functions, regardless of whether these individuals are employed by the
registrant or a third party, and that relates to any element of the code of
ethics definition enumerated in paragraph (b) of this Item. The registrant must

 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.
