The housing and auto sectors continue to recover, benefiting from record-low interest rates. Banks' willingness to lend to consumers and businesses also continues to rise, broad measures of inflation remain subdued, and, if the weather cooperates in 2013, food prices should come back down. And, while corporate profit growth has slowed, profits remain high and many U.S. companies continue to both pay and increase dividends*. Offsetting some of these positives are the continued contraction of fiscal policy in Washington and a recessionary Europe. The Federal Reserve's aggressive monetary policy has driven Treasury yields to generational lows and supported investments in all financial assets, including equities and high-yield corporate bonds. For example, the Standard & Poor's 500 Index (the S&P 500), a broad measure of the U.S. stock market, returned 15.99% for the full calendar year ended December 31, 2012, and the Bank of America Merrill Lynch High Yield Master II Index (the High Yield Index), which measures the performance of high-yield corporate bonds, returned 15.59% for the same 12-month period. On the other hand, the Barclays Aggregate Bond Index (the Aggregate Index), which tracks the performance of a higher-quality bond universe, gained 4.22% for the 12 months ended December 31, 2012; the safer-still Barclays Government Credit Index (the Government/Credit Index) returned 4.82%; and 3-month Treasury bills, generally regarded as essentially "risk free" by the markets, returned just 0.09% in 2012. "Risky" assets outperformed again in the first quarter of 2013, as the S&P 500 returned 10.60% and the High Yield Index returned 2.89%. In contrast, the Aggregate Index returned -0.12% in the first quarter, the Government Credit Index returned -0.16%, and Treasury bills returned 0.02%. Despite generally improving economic conditions and a rising stock market, global economies and investors still face daunting challenges as 2013 moves forward, although we remain cautiously optimistic. U.S. fiscal policy remains unsettled, and we feel the U.S. government could be at risk of credit rating downgrades from one or more of the major ratings agencies if the uncertainties persist. The Federal Reserve continues to provide extraordinary support to the U.S. economy and the bond market, but will not do so indefinitely. Europe has made progress, but has not yet resolved its sovereign-debt/banking problem, nor has the region been able to exit recession. Japan recently has unveiled aggressive and unconventional monetary and fiscal policies, but the country * Dividends are not guaranteed. 2 Pioneer Equity Income Fund | Semiannual Report | 4/30/13 continues to face issues such as high levels of debt as well as an aging population. China and other emerging economies, while generally in better shape than most "developed" markets, also face a range of challenges. While most of the risks outlined here are widely recognized and may already be "priced in" to 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. Pioneer's investment teams have, since 1928, sought out attractive opportunities in global equity and bond markets, using in-depth research to identify undervalued individual securities, and using thoughtful risk management to construct portfolios which balance potential risks and reward in an ever-changing world. We encourage you to learn more about Pioneer and our time-tested approach to investing by consulting with your financial advisor or visiting us online at us.pioneerinvestments.com. We greatly appreciate your trust in us, and we thank you for investing with Pioneer. Sincerely, /s/ Daniel K. Kingsbury Daniel K. Kingsbury President and CEO Pioneer Investment Management USA, Inc.

Pioneer Equity Income Fund | Semiannual Report | 4/30/13 3 Portfolio Management Discussion | 4/30/13 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, 2013, 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 months ended April 30, 2013, particularly for the types of equities deemed appropriate for Pioneer Equity Income Fund? A After just a mild stumble at the very beginning of the period in the fall of 2012, the stock market trended steadily higher throughout the six months ended April 30, 2013. The imminence of the so-called "fiscal cliff" caused some jitters in the last two weeks of December, but when political leaders in Washington, D.C., cobbled together a deal right at year end, the equity market took off again. The underlying reasons for the strength of the stock market during the period were good corporate earnings, continued (if moderate) economic growth, merger-and-acquisition activity, dividend increases and share repurchases by companies, improved housing numbers, better employment statistics, and renewed interest in stocks on the part of investors still allocated heavily to bonds and money market instruments. The Fund takes a special interest in dividend-paying stocks and has generally emphasized established companies with long business histories. Such companies, especially those in the consumer staples, health care, and utilities sectors, were popular with investors during the six-month period. Mergers and acquisitions also touched two of the Fund's holdings: in February, H. J Heinz received a premium take-over bid from Berkshire Hathaway and a Brazilian company called 3G Capital; and in April, DE Master Blenders, part of the Fund's former holding Sara Lee, received a premium offer from the German-led investment firm JAB. Q How did the Fund perform in that environment during the six months ended April 30, 2013? A Pioneer Equity Income Fund's Class A shares returned 15.79% at net asset value during the six months ended April 30, 2013, while the Fund's benchmark, the Russell 1000 Value Index (the Russell Index), returned 16.31%. During the same period, the average return of the 374 mutual funds in Lipper's Equity Income Funds category was 14.08%. 4 Pioneer Equity Income Fund | Semiannual Report | 4/30/13 Q Could you please talk in more detail about the Fund's performance during the six months ended April 30, 2013? Please discuss the slight underperformance of the Fund relative to its benchmark, the Russell Index. A While overall the Fund recorded strongly positive returns during the six-month period, stock selection results in financials and information technology did hold back relative performance somewhat. In financials, the so-called money-center banks, especially Bank of America, surged during the period, and while the Fund did own shares in that industry, including shares of Bank of America, the portfolio's underweight position compared with that of the Russell Index benchmark hurt relative performance. The portfolio's underweight was due to the modest nature of the dividends currently paid by most of the giant banks. Since the "sub-prime meltdown" of 2007-2009, the Federal Reserve (the Fed) has restricted dividend payments by the institutions most involved in the activities leading to the financial crisis. In information technology, the Fund was not invested in Hewlett-Packard, which enjoyed a very impressive share-price recovery during the period on the back of cost cuts that kept earnings higher than many investors expected. With that said, we continue to have questions about the probability of resumed business growth for the company. On the positive side, the Fund benefited from very good stock selection in energy and consumer staples during the six-month period. The Fund's position in Marathon Petroleum, a refiner, transporter, and marketer of petroleum products, recorded a splendid share-price advance as oil prices remained under control and demand improved with the better economy. In consumer staples, in addition to the aforementioned acquisition offers for H.J. Heinz and DE Master Blenders, the Fund saw very good share-price increases from positions in Hershey and Campbell Soup as investors found themselves attracted to companies they thought offered relatively stable long-term growth prospects, without so much risk of product obsolescence or government regulation. Q Could you please discuss the changes that you made to the Fund's portfolio during the six months ended April 30, 2013? A During the six-month period we added 16 positions to the portfolio and liquidated nine. Three of the new names in the portfolio--Wal-Mart Stores, PepsiCo, and Procter & Gamble--were in the consumer staples sector, where we have continued to find stocks of companies we think can grow on a worldwide basis, while having a prominent market presence in the United States. A "special situation" we were able to add to the portfolio within the materials sector is Givaudan, a flavors and fragrances supplier to food Pioneer Equity Income Fund | Semiannual Report | 4/30/13 5 manufacturers and perfumeries. Several of the Fund's new positions were in health care--the large pharmaceutical producers Eli Lilly, Novartis, and AstraZeneca. In addition, the portfolio received shares of AbbVie when an existing Fund holding, Abbott Laboratories, split off its pharmaceutical business; and we purchased shares of Zoetis, an animal-health-medicines company, when Pfizer, also a Fund holding, had an initial public offering for that profitable division of its business. Other initial purchases during the period included Joy Global, maker of mining machinery; Electrolux, manufacturer not only of the well-known vacuum cleaners but also of a whole range of household appliances; Coach, maker of ladies' handbags and accessories as well as of comparable products for men; SWEDBANK, a leading retail and commercial bank based in Stockholm, Sweden; Allstate, the home and auto insurer; Intel, the major semiconductor designer and fabricator; and NextEra Energy, a large electric utility headquartered in Florida. Among stocks sold from the portfolio during the period were several that we felt had reached fair value, including EQT and Snap-on; some where we had come to question the companies' longer-term earnings potential, including Cleveland Cliffs, Newmont Mining, and Century Link; and others we just regarded as having less compelling prospects than those of companies whose stocks we wished to purchase. 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 months ended April 30, 2013? A Definitely positive! However, we must hasten to add that the investment experience even of the recent past is no guarantee of continued good conditions for particular stocks in upcoming periods. But actually for some time now, investors have been interested in dividend-paying stocks because of the sometimes-favorable comparisons between current yields on investment-grade bonds and stocks, with the additional potential, in the case of stocks, for dividend increases over time. While we do not expect a wholesale shift from bonds into stocks, we do think it likely that many investors will continue at least to consider stocks for their portfolios. Companies, for their part, have found that they can attract positive attention by declaring and increasing dividends. Fortunately, too, the Federal tax changes instituted as part of the year-end "fiscal cliff" resolution did not alter by very much the maximum Federal income taxes payable by individuals on their dividend income. 6 Pioneer Equity Income Fund | Semiannual Report | 4/30/13 Q Given the various potential headwinds for the global economy, what is your outlook for the remainder of 2013? A Certainly there are risks and uncertainties for the global economy. Europe remains sluggish; growth in China appears to have slowed over the past couple of years from its former, very robust rate; Brazil, Argentina, and Venezuela, among other Latin American countries, have been experiencing difficulties; and here in the U.S., the national fiscal situation continues to cause unease. Besides the economic issues, there are also some obvious geopolitical trouble spots in the world, including the Middle East and the Korean peninsula. However, when we look at the U.S., the principal economic arena for the majority of our portfolio's companies, we see steady, if moderate, growth that we think can be sustained at least over the next couple of years by improvement in the housing sector, higher auto sales, and falling unemployment. The domestic economy, unlike economies in some other parts of the world, is predominantly dependent on the state of the consumer and the level of consumer confidence. A better housing market can go a long ways all by itself towards creating a more upbeat set of economic conditions. Next to the potential for the U.S. economy to keep expanding we would set the historically reasonable level of share-price valuations and the decent dividend yields relative to income-generating alternatives like money-market instruments and investment-grade bonds. So, headwinds, yes, but also, perhaps, some tailwinds. We shall see in the months and quarters ahead where the prevailing winds blow. Thank you for your interest and support.

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 would have been higher than the performance shown. 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.

For the period beginning on April 1, 2003, the actual performance of Class R shares is reflected. Class R shares are not subject to sales charges and are available for limited groups of eligible investors, including institutional investors.

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

Pioneer Equity Income Fund | Semiannual Report | 4/30/13 17 Comparing Ongoing Fund Expenses As a shareowner in the Fund, you incur two types of costs: (1) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses; and (2) transaction costs, including sales charges (loads) on purchase payments. This example is intended to help you understand your ongoing expenses (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 at the beginning of the Fund's latest six-month period and held throughout the six months. Using the Tables -------------------------------------------------------------------------------- Actual Expenses The first table below provides information about actual account values and actual expenses. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period as follows: (1) Divide your account value by $1,000 Example: an $8,600 account value (divided by) $1,000 = 8.6 (2) Multiply the result in (1) above by the corresponding share class's number in the third row under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Expenses Paid on a $1,000 Investment in Pioneer Equity Income Fund Based on actual returns from November 1, 2012 through April 30, 2013. ----------------------------------------------------------------------------------------------------- Share Class A B C K R Y Z ----------------------------------------------------------------------------------------------------- Beginning Account $1,000.00 $1,000.00 $1,000.00 $1,000.00 $1,000.00 $1,000.00 $1,000.00 Value on 11/1/12** ----------------------------------------------------------------------------------------------------- Ending Account $1,157.90 $1,152.10 $1,154.00 $1,129.90 $1,156.10 $1,160.00 $1,159.10 Value (after expenses) on 4/30/13 ----------------------------------------------------------------------------------------------------- Expenses Paid $5.99 $11.74 $10.09 $2.62 $7.64 $4.28 $4.93 During Period* ----------------------------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized net expense ratio plus the expense ratios of the underlying funds. These combined totals were 1.12%, 2.20%, 1.89%, 0.68% 1.43%, 0.80%, and 0.92% for Class A, Class B, Class C, Class K, Class R, Class Y and Class Z shares, respectively. These combined ratios were multiplied by the average account value over the period, and then multiplied by 181/365 (132/365 for Class K shares) (to reflect the one-half year period) to calculate the "Expenses Paid During Period" in the table above. ** 12/20/12 for Class K shares. 18 Pioneer Equity Income Fund | Semiannual Report | 4/30/13 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. Expenses Paid on a $1,000 Investment in Pioneer Equity Income Fund Based on a hypothetical 5% return per year before expenses, reflecting the period from November 1, 2012 through April 30, 2013. ------------------------------------------------------------------------------------------------------ Share Class A B C K R Y Z ------------------------------------------------------------------------------------------------------ Beginning Account $1,000.00 $1,000.00 $1,000.00 $1,000.00 $1,000.00 $1,000.00 $1,000.00 Value on 11/1/12** ------------------------------------------------------------------------------------------------------ Ending Account $1,019.24 $1,013.88 $1,015.42 $1,015.62 $1,017.70 $1,020.83 $1,020.23 Value (after expenses) on 4/30/13 ------------------------------------------------------------------------------------------------------ Expenses Paid $5.61 $10.99 $9.44 $2.48 $7.15 $4.01 $4.61 During Period* ------------------------------------------------------------------------------------------------------ * Expenses are equal to the Fund's annualized net expense ratio plus the expense ratios of the underlying funds. These combined totals were 1.12%, 2.20%, 1.89%, 0.68% 1.43%, 0.80%, and 0.92% for Class A, Class B, Class C, Class K, Class R, Class Y and Class Z shares, respectively. These combined ratios were multiplied by the average account value over the period, and then multiplied by 181/365 (132/365 for Class K shares) (to reflect the one-half year period) to calculate the "Expenses Paid During Period" in the table above. ** 12/20/12 for Class K shares.

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 | 4/30/13 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 their 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 or at the direction or with the approval of the Valuation Committee using fair value methods pursuant to procedures adopted by the Board of Trustees. The Valuation Committee is comprised of certain members of the Board of Trustees. 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. Pioneer Investment Management, Inc. (PIM) 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. At April 30, 2013, there were no securities that were valued using fair value methods (other than securities that were valued using prices supplied by independent pricing services). Inputs used when applying fair value methods to value a security may include credit ratings, the financial condition of the company, current market conditions and comparable securities. 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. Pioneer Equity Income Fund | Semiannual Report | 4/30/13 39 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, 2013, the Fund did not have any interest and penalties related to unrecognized tax positions, which, if applicable, would be recorded as an income tax expense in the Statement of Operations. Tax years for the prior three fiscal years remain 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 Fund's taxable year. The tax character of distributions paid during the year ended October 31, 2012 was as follows: ---------------------------------------------------------------------------- 2012 ---------------------------------------------------------------------------- Distributions paid from: Ordinary income $35,055,310 ---------------------------------------------------------------------------- Total $35,055,310 ============================================================================ The following shows the components of distributable earnings on a federal income tax basis at October 31, 2012: ---------------------------------------------------------------------------- 2012 ---------------------------------------------------------------------------- Distributable earnings: Undistributed ordinary income $ 8,806,266 Capital loss carryforward (54,425,123) Net unrealized gain 261,381,038 ---------------------------------------------------------------------------- Total $215,762,181 ============================================================================ The difference between book-basis and tax-basis net unrealized gain is attributable to the tax deferral of losses on wash sales, the tax basis adjustments on partnerships, and REIT holdings. 40 Pioneer Equity Income Fund | Semiannual Report | 4/30/13 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 $49,572 in underwriting commissions on the sale of Class A shares during the six months ended April 30, 2013. 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 gains or losses are recorded in the Fund's financial statements. The Fund records realized gains and losses at the time a portfolio hedge is offset by entry into a closing transaction or extinguished by delivery of the currency. Risks may arise upon entering into these contracts from the potential inability of counterparties to meet the terms of the contract and from unanticipated movements in the value of foreign currencies relative to the U.S. dollar (see Note 8). Pioneer Equity Income Fund | Semiannual Report | 4/30/13 41 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, 2013, 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 $109,739 in management fees, administrative costs and certain other reimbursements payable to PIM at April 30, 2013. 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, 2013, such out-of-pocket expenses by class of shares were as follows: -------------------------------------------------------------------------------- Shareholder Communications: -------------------------------------------------------------------------------- Class A $396,492 Class B 7,955 Class C 53,323 Class R 91,384 Class Y 186,845 Class Z 2,206 -------------------------------------------------------------------------------- Total $738,205 ================================================================================ Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $303,287 in transfer agent fees and out-of-pocket reimbursements payable to PIMSS at April 30, 2013. 42 Pioneer Equity Income Fund | Semiannual Report | 4/30/13 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 $38,606 in distribution fees payable to PFD at April 30, 2013. 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. 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 one year of purchase are subject to a CDSC of 1.00%, based on the lower of cost or market value of shares being redeemed. Shares purchased as part of an exchange remain subject to any CDSC that applied to the original purchase of those shares. There is no CDSC for Class K, Class R, Class Y or Class Z shares. Proceeds from the CDSCs are paid to PFD. For the six months ended April 30, 2013, CDSCs in the amount of $11,616 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, 2013, the Fund's expenses were not reduced under such arrangements. Pioneer Equity Income Fund | Semiannual Report | 4/30/13 43 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 as of February 15, 2012 is 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 0.90% 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, 2013, 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 with affiliates of the Fund for the six months ended April 30, 2013: -------------------------------------------------------------------------------------------- Beginning Corporate Ending Balance Purchases Sales Actions Balance Dividend Affiliates (shares) (shares) (shares) (shares) (shares) Income Value -------------------------------------------------------------------------------------------- The Gorman- Rupp Co. 1,146,943 -- -- -- 1,146,943 $229,389 $32,401,140 8. Forward Foreign Currency Contracts At April 30, 2013, the Fund had entered into various forward foreign currency contracts that obligate the Fund to deliver or take delivery of currencies at specified future maturity dates. Alternatively, prior to the settlement date of a forward foreign currency contract, the Fund may close out such contract by entering into an offsetting contract. The average value of contracts open during the six months ended April 30, 2013 was $72,406. At April 30, 2013, the Fund had no outstanding portfolio hedges. At April 30, 2013, the Fund's gross forward currency settlement contracts receivable and payable were $185,490 and $186,806, respectively, resulting in a net payable of $1,316. 44 Pioneer Equity Income Fund | Semiannual Report | 4/30/13 9.

(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 2012 as the Trustees of the Fund agreed on, among other things, an overall approach and timeline for the process. In July 2012, 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 2012 and September 2012. 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, October, and November, 2012 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 each regularly scheduled meeting. At a meeting held on November 13, 2012, 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. 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, its research process and its process for trade execution. The Trustees considered the resources of PIM and the personnel of PIM who provide investment management services to the Fund. The Trustees considered the non-investment resources and personnel of PIM involved in PIM's services to the Fund, including PIM's compliance and legal resources and personnel. The Trustees also considered the substantial attention and high priority given by PIM's senior management to the Pioneer fund complex. In addition, the Trustees considered PIM's plans to increase resources in its investment management function and other enhancements to PIM's advisory capabilities. 46 Pioneer Equity Income Fund | Semiannual Report | 4/30/13 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 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 second quintile of its Morningstar category for the one and five year periods ended June 30, 2012, and in the first quintile of its Morningstar category for the five year period ended June 30, 2012. (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 discussed the Fund's performance record. They indicated that they were satisfied with the discussions with PIM with respect to the Trust'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 Independent Trustees for this purpose using data provided by Strategic Insight Mutual Trust 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, 2012 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 on assets over $10 billion. The Trustees considered that the Fund's expense ratio for the twelve months ended June 30, 2012 was in the third quintile relative to its Strategic Insight peer group for the comparable period. Pioneer Equity Income Fund | Semiannual Report | 4/30/13 47 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 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 48 Pioneer Equity Income Fund | Semiannual Report | 4/30/13 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 Funds. 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 Funds. 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 also considered the benefits to the Fund and to PIM and its affiliates from the use of "soft" commission dollars generated by the Fund to pay for research and brokerage services. The Trustees 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.
