We believe the theme for the economy in 2011 may be modest but positive growth. The private sector is showing signs of slow but steady improvement, led by higher capital investment, solid exports, improved consumption, and gradually rising demand for consumer auto loans and commercial loans. At the same time, the risks to a steady recovery remain substantial, including the continued delays in the housing sector's recovery, rising oil prices, and the fiscal drag of U.S. federal and state budget cuts. We are concerned about the long-term risk of inflation in an environment of accommodative Fed policy, continued low nominal and "real" interest rates and rising commodity prices. The recovery process may occur more slowly than many would like, and will almost certainly be accompanied by short-term market swings. But our investment professionals are finding good opportunities to invest. Through the first quarter of 2011, although bonds remained popular with investors, we believed there was value in the equity market. In both equity and bond markets, we are finding good opportunities to invest using the same disciplined approach we have used at Pioneer since 1928, which is to focus on identifying undervalued individual securities with the greatest potential for success, carefully weighing risk against reward. Our teams of investment professionals continually monitor and analyze the relative valuations of different sectors and securities globally to help build portfolios that we believe can help you achieve your investment goals. At Pioneer, we have long advocated the benefits of staying diversified and investing for the long term. The strategy has generally performed well for many investors. For instance, bond markets certainly rewarded investors for most of 2010, even though equity valuations seemed quite reasonable and were inexpensive relative to bonds and compared with historic levels -- conditions which represented potentially good value for long-term investors. 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. There is no single best strategy that works for every investor. 2 Pioneer Equity Income Fund | Semiannual Report | 4/30/11 We invite you to learn more about Pioneer and our time-tested approach to investing by consulting with your financial advisor or visiting us online at www.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 | 4/30/11 3 Portfolio Management Discussion | 4/30/11 In the following interview, John Carey, Executive Vice President and Head of the U.S. Core Value Department at Pioneer Investments, discusses the investment environment during the six-month period ended April 30, 2011, and Pioneer Equity Income Fund's performance. Mr. Carey is responsible for the day-to-day management of Pioneer Equity Income Fund. Q How did the Fund perform over the six months ended April 30, 2011? A Over the six months ended April 30, 2011, Pioneer Equity Income Fund Class A shares returned 17.84% at net asset value, while the Fund's benchmark, the Russell 1000 Value Index (the Russell Index), returned 17.29%. Over the same period, the average return of the 287 mutual funds in Lipper's Equity Income Funds category was 15.56%. Q How would you describe the markets for equities over the six months ended April 30, 2011, particularly for the types of equities deemed appropriate for the Fund? A It was a generally very strong period for stocks. Supported by earnings increases and improved economic conditions, stock prices trended higher throughout the six-month period. There were setbacks -- from an earthquake and tsunami in Japan, leading to parts shortages in the technology and automotive industries, and political upheaval in the Middle East, contributing to a spike in oil prices; but on the whole investors managed to look through the near-term difficulties and focus on a longer-term picture of encouraging business conditions. Though the economic expansion continued to be slow and unemployment remained high during the period, the direction of most economic indicators was positive and business as well as consumer sentiment improved. As capacity utilization in particular increased, businesses undertook more capital spending and also looked to make acquisitions. Strong cash flows led to higher dividend payments, and we also saw larger share-repurchase activity. One concern must certainly be cost increases, both of raw materials and labor. Opinion on whether there is inflation risk continues to be mixed, but unquestionably there are beginning to be pressures on corporate profit margins from the higher costs. There also persist some bigger issues about which investors are understandably concerned, principally the instability of the European monetary system and the high federal budget deficit in the United States. Truly, in investing, the coast is never clear, the sailing is never smooth, the stage is never shadowless. 4 Pioneer Equity Income Fund | Semiannual Report | 4/30/11 Q The Fund's Class A shares showed a strong return over the six months ended April 30, 2011, outpacing the return for the Fund's benchmark, the Russell Index. What were the main reasons for that? A Our sector allocations were the main contributors to the Fund's positive relative performance. The Fund was significantly underweight the below- average-performing financials sector, and overweight the above-average- performing industrials and materials sectors. Except in health care, where the Fund's stock holdings performed more poorly than average for the sector, our stock selections for the most part were also positive contributors to relative performance. Among the Fund's notably successful stocks during the period were: Marathon Oil, which announced a major restructuring; Gorman-Rupp, which has seen a good uptick in its waste-water pump business with all of the floods and heavy rains of these past months; and Helmerich & Payne, whose land drilling rigs have been much in demand by oil and gas exploration and development firms during this period of high energy prices. As noted above, some the Fund's holdings in health care underperformed the overall sector during the six-month period. Within health care, one notable underperformer held in the Fund's portfolio was Abbott Laboratories. In its nutritional division, the company had a costly recall in its infant-formula business, and within its pharmaceutical operations Abbott saw some slowing in the rate of growth for its important arthritis drug, Humira. Q Could you please discuss any changes you have made to the Fund's portfolio during the six months ended April 30, 2011. A We added ten positions to the Fund's portfolio and liquidated nine during the six-month period. Ecolab, a supplier of industrial and commercial cleaning chemicals, is a beneficiary of higher plant utilization. Campbell Soup, the food-processing company, is under way with another strategic review. The company has always been quite profitable; what has been needed is a sound plan for growth. Becton Dickinson is a leading, worldwide supplier of hospital supplies and medical devices, well positioned to address demand for better-quality health care. Likewise, Smith & Nephew is prominent as a producer of orthopedic implants and surgical supplies. PNC Financial Services appears to be one of the stronger regional banks to emerge from the subprime meltdown of 2007-09. Linear Technology, which makes integrated circuits, is yet another example of the dividend-paying stocks now available in the information technology sector. Finally, we re-arranged the Fund's investments in utilities, buying American Electric Power, Ameren, Consolidated Edison, and American Water Works, while selling Duke Energy and Wisconsin Energy. The overall effect of the changes to the portfolio in that sector was a slight enhancement of income. Pioneer Equity Income Fund | Semiannual Report | 4/30/11 5 We also sold, generally at meaningful profits, Carpenter Technology, Nucor, Illinois Toolworks, PACCAR, Walgreen, JPMorgan Chase, and T. Rowe Price Group. In most cases, the stocks had reached our target prices and we thought there were more reasonable values elsewhere. Q The Fund typically places an important emphasis on dividend-paying stocks. Would you say that dividends have returned to their pre-financial crisis levels, or is there still room for improvement in dividend payments? A While there has been a sharp increase in the number of companies raising their dividends over the past two years, we believe that we shall see many more dividend increases over the next couple of years as the economy continues to grow. In the financials sector, where the dividend cuts were among the most significant during the time of crisis, we are starting to see more generous payments; and particularly in that sector we believe that there is much potential for further dividend enhancement. In fact, in a recent press release, Standard & Poor's said that there could even be a second round of dividend increases by the financials later this year or early next year. The extension of the favorable federal tax treatment for qualified dividends through this year and next may also tend to incline companies towards raising dividends. Q What is your outlook for the remainder of 2011? A Though we remain constructive on the economy, some investors have become more cautious in recent months and have adopted a more "defensive" posture. That repositioning is apparent in the better relative performance of late of some of the sectors traditionally regarded as more conservative from the point of view of valuation, and more resilient in regard to earnings and cash-flow stability, including health care, utilities, and consumer staples. At the same time, there has been some "correction" in the prices of stocks judged to be more economically sensitive or cyclically exposed. Fortunately, the Pioneer Equity Income Fund's portfolio is always diversified, and so we have a mix of companies, including some with more "steady Eddie" characteristics and others with businesses that do rise and fall to an extent with the general level of industrial activity and consumer spending. What unites all of the Fund's holdings, however, is the emphasis on dividend payments, and that usually means that the companies, even if cyclical, have enough predictability in their operations that their managements can plan ahead financially and pay attention to the needs of their shareholders for long-term returns. In the months ahead, we shall most likely make occasional changes in the Fund's portfolio, but rather than introducing the changes because of some overarching, macroeconomic view, we shall instead be buying or selling stocks on the basis of our individual-company analysis. That has been our long-standing practice. Thank you as always for your support. 6 Pioneer Equity Income Fund | Semiannual Report | 4/30/11 Please refer to the Schedule of Investments on pages 18-25 for a full listing of Fund securities.

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, 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. 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 net expense ratio reflects contractual expense limitations currently in effect through March 1, 2012, for Class Z shares. There can be no assurance that Pioneer will extend the expense limitations beyond such time. Please see the prospectus and financial statements for more information. The 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. Pioneer Equity Income Fund | Semiannual Report | 4/30/11 15 Comparing Ongoing Fund Expenses As a shareowner in the Fund, you incur two types of costs: (1) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses; and (2) transaction costs, including sales charges (loads) on purchase payments. This example is intended to help you understand your ongoing expenses (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 at the beginning of the Fund's latest six-month period and held throughout the six months. Using the Tables -------------------------------------------------------------------------------- Actual Expenses The first table below provides information about actual account values and actual expenses. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period as follows: (1) Divide your account value by $1,000 Example: an $8,600 account value [divided by] $1,000 = 8.6 (2) Multiply the result in (1) above by the corresponding share class's number in the third row under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Expenses Paid on a $1,000 Investment in Pioneer Equity Income Fund Based on actual returns from November 1, 2010 through April 30, 2011. --------------------------------------------------------------------------------------------------------------------------- Share Class A B C R Y Z --------------------------------------------------------------------------------------------------------------------------- Beginning Account $ 1,000.00 $ 1,000.00 $ 1,000.00 $ 1,000.00 $ 1,000.00 $ 1,000.00 Value on 11/1/10 --------------------------------------------------------------------------------------------------------------------------- Ending Account Value $ 1,178.40 $ 1,172.40 $ 1,174.30 $ 1,177.30 $ 1,180.90 $ 1,180.60 (after expenses) on 4/30/11 --------------------------------------------------------------------------------------------------------------------------- Expenses Paid $ 6.27 $ 11.47 $ 10.30 $ 7.61 $ 4.11 $ 4.22 During Period* --------------------------------------------------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.16%, 2.13%, 1.91%, 1.41%, 0.76%, and 0.78% for Class A, Class B, Class C, Class 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). 16 Pioneer Equity Income Fund | Semiannual Report | 4/30/11 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.

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 six classes of shares designated as Class A, Class B, Class C, Class R, Class Y and Class Z shares. Class R shares commenced operations on April 1, 2003. Class Z shares were first publicly offered on July 6, 2007. Effective as of the close of business on December 31, 2009, Class B shares are no longer offered to new or existing shareholders, except that dividends and/or capital gain distributions may continue to be reinvested in Class B shares, and shareholders may exchange their Class B shares for Class B shares of other Pioneer funds, as permitted by existing exchange privileges. Each class of shares represents an interest in the same portfolio of investments of the Fund and has identical rights (based on relative net asset values) to assets and liquidation proceeds. Share classes can bear different rates of class-specific fees and expenses such as transfer agent and distribution fees. Differences in class-specific fees and expenses will result in differences in net investment income and, therefore, the payment of different dividends from net investment income earned by each class. The Amended and Restated Declaration of Trust of the Fund gives the Board the flexibility to specify either per-share voting or dollar-weighted voting when submitting matters for shareholder approval. Under per-share voting, each share of a class of the Fund is entitled to one vote. Under dollar-weighted voting, a shareholder's voting power is determined not by the number of shares owned, but by the dollar value of the shares on the record date. Each share class has exclusive voting rights with respect to matters affecting only that class, including with respect to the distribution plan for that class. There is no distribution plan for Class Y or Class Z shares. Class B shares convert to Class A shares approximately eight years after the date of purchase. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making the Fund more susceptible to any economic, political or regulatory developments or other risks affecting those industries 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. The Fund's financial statements have been prepared in conformity with U.S. generally accepted accounting principles that require the management of the 36 Pioneer Equity Income Fund | Semiannual Report | 4/30/11 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: A. Security Valuation Security transactions are recorded as of trade date. The net asset value of the Fund is computed once daily, on each day the New York Stock Exchange (NYSE) is open, as of the close of regular trading on the NYSE. In computing the net asset value, securities that have traded on an exchange are valued at the last sale price on the principal exchange where they are traded. Securities that have not traded on the date of valuation, or securities for which sale prices are not available, generally are valued at the mean between the last bid and asked prices. Securities for which market prices and/or quotations are not readily available or are considered to be unreliable are valued using fair value methods pursuant to procedures adopted by the Board of Trustees. Trading in foreign securities is substantially completed each day at various times prior to the close of the NYSE. The values of such securities used in computing the net asset value of the Fund's shares are determined as of such times. The Fund may use fair value methods if it is determined that a significant event has occurred after the close of the exchange or market on which the security trades and prior to the determination of the Fund's net asset value. Thus, the valuation of the Fund's securities may differ from exchange prices. At April 30, 2011, there were no securities that were valued using fair value methods (other than securities that were valued using prices supplied by independent pricing services). Inputs used when applying fair value methods to value a security may include credit ratings, the financial condition of the company, current market conditions and comparable securities. Short-term fixed income securities with remaining maturities of sixty days or less generally are valued at amortized cost. Money market mutual funds are valued at net asset value. Dividend income is recorded on the ex-dividend date, except that certain dividends from foreign securities where the ex-dividend date may have passed are recorded as soon as the Fund becomes aware of the ex-dividend data in the exercise of reasonable diligence. Interest income, including interest on income bearing cash accounts, is recorded on the accrual basis. Pioneer Equity Income Fund | Semiannual Report | 4/30/11 37 Dividend and interest income are reported net of unrecoverable foreign taxes withheld at the applicable country rates. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. B. Federal Income Taxes It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income and net realized capital gains, if any, to its share-owners. Therefore, no federal income tax provision is required. Tax years for the prior three fiscal years remain subject to examination by tax authorities. The amounts and characterizations of distributions to shareowners for financial reporting purposes are determined in accordance with federal income tax rules. Therefore, the sources of the Fund's distributions may be shown in the accompanying financial statements as from or in excess of net investment income or as from net realized gain on investment transactions, or as from paid-in capital, depending on the type of book/tax differences that may exist. The tax character of current year distributions payable will be determined at the end of the current taxable year. The tax character of distributions paid during the year ended October 31, 2010 was as follows: -------------------------------------------------------------------------------- 2010 -------------------------------------------------------------------------------- Distributions paid from: Ordinary income $15,720,312 -------------------------------------------------------------------------------- Total $15,720,312 ================================================================================ The following shows the components of distributable earnings on a federal income tax basis at October 31, 2010: -------------------------------------------------------------------------------- 2010 -------------------------------------------------------------------------------- Distributable earnings: Undistributed ordinary income $ 659,959 Capital loss carryforward (219,763,797) Unrealized appreciation 275,610,888 -------------------------------------------------------------------------------- Total $ 56,507,050 ================================================================================ The difference between book-basis and tax-basis unrealized appreciation is attributable to the tax deferral of losses on wash sales, the tax basis adjustments on partnerships, and REIT holdings. 38 Pioneer Equity Income Fund | Semiannual Report | 4/30/11 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 $38,296 in underwriting commissions on the sale of Class A shares during the six months ended April 30, 2011. 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 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 R, Class Y and Class Z shares can reflect different transfer agent and distribution expense rates. E. Repurchase Agreements With respect to repurchase agreements entered into by the Fund, the value of the underlying securities (collateral), including accrued interest, is required to be equal to or in excess of the repurchase price. The collateral for all repurchase agreements is held in safekeeping in the customer-only account of the Fund's custodian or a subcustodian of the Fund. The Fund's investment adviser, Pioneer Investment Management, Inc. (PIM), is responsible for determining that the value of the collateral remains at least equal to the repurchase price. F. Securities Lending The Fund lends securities in its portfolio to certain broker-dealers or other institutional investors. When entering into a securities loan transaction, the Fund typically receives cash collateral from the borrower equal to at least the value of the securities loaned, which is invested in temporary investments. Credit Suisse AG, New York Branch, as the Fund's securities lending agent, manages the Fund's securities lending collateral. The income earned on the investment of collateral is shared with the borrower and the lending agent in payment of any rebate due to the borrower with respect to the securities Pioneer Equity Income Fund | Semiannual Report | 4/30/11 39 loan, and in compensation for the lending agent's services to the Fund. The Fund also continues to receive payments in lieu of dividends or interest on the securities loaned. Gain or loss on the value of the loaned securities that may occur during the term of the loan will be for the account of the Fund. The amount of the collateral is required to be adjusted daily to reflect any price fluctuation in the value of the loaned securities. If the required market value of the collateral is less than the value of the loaned securities, the borrower is required to deliver additional collateral for the account of the Fund prior to the close of business on that day. The Fund has the right, under the lending agreement, to terminate the loan and recover the securities from the borrower with prior notice. The Fund is required to return the cash collateral to the borrower and could suffer a loss if the value of the collateral, as invested, has declined. 2. Management Agreement PIM, a wholly owned indirect subsidiary of UniCredit, manages the Fund's portfolio. 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% of the excess over $10 billion. For the six months ended April 30, 2011, the effective management fee (excluding waivers and/or assumption of expenses) was equivalent to 0.60% of the Fund's average daily net assets. Pioneer has contractually agreed to limit ordinary operating expenses to the extent required to reduce Class Z expenses to 0.85% of the average daily net assets attributable to Class Z shares. This expense limitation is in effect through March 1, 2012. There can be no assurance that PIM will extend the expense limitation agreement beyond the date referred to above. 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 $40,415 in management fees, administrative costs and certain other reimbursements payable to PIM at April 30, 2011. 3. Transfer Agent PIMSS, a wholly owned indirect subsidiary of UniCredit, provides substantially all transfer agent and shareowner services to the Fund at negotiated rates. 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. 40 Pioneer Equity Income Fund | Semiannual Report | 4/30/11 For the six months ended April 30, 2011, such out-of-pocket expenses by class of shares were as follows: -------------------------------------------------------------------------------- Shareholder Communications: -------------------------------------------------------------------------------- Class A $405,604 Class B 13,904 Class C 42,869 Class R 86,570 Class Y 71,535 Class Z 110 -------------------------------------------------------------------------------- Total $620,592 ================================================================================ Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $156,762 in transfer agent fees and out-of-pocket reimbursements payable to PIMSS at April 30, 2011. 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 $18,838 in distribution fees payable to PFD at April 30, 2011. 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 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 18 months of purchase (within 12 months for purchases made on or after April 1, 2009). 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. Pioneer Equity Income Fund | Semiannual Report | 4/30/11 41 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 R, Class Y or Class Z shares. Proceeds from the CDSCs are paid to PFD. For the six months ended April 30, 2011, CDSCs in the amount of $12,678 were paid to PFD. 5. Expense Offset Arrangements The Fund has entered into certain expense offset arrangements with PIMSS resulting in a reduction in the Fund's total expenses due to interest earned on cash held by PIMSS. For the six months ended April 30, 2011, the Fund's expenses were not reduced under such arrangements. 6. Line Of Credit Facility The Fund, along with certain other funds in the Pioneer Family of Funds (the Funds), participates in a $165 million committed, unsecured revolving line of credit facility. Borrowings are used solely for temporary or emergency purposes. The Fund may borrow up to the lesser of the amount available under the facility or the limits set for borrowing by the Fund's prospectus and the 1940 Act. Interest on borrowings is payable at the higher of the London Interbank Offered Rate (LIBOR) on the borrowing date plus 1.25% on an annualized basis or the Federal Funds Rate on the borrowing date plus 1.25% on an annualized basis. The Funds pay an annual commitment fee for this facility. The commitment fee is allocated among participating Funds based on an allocation schedule set forth in the credit agreement. For the six months ended April 30, 2011, the Fund had no borrowings under this agreement. 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, 2011: -------------------------------------------------------------------------------------------------------- Beginning Corporate Ending Balance Purchases Actions Balance Dividend Affiliates (shares) (shares) (shares) (shares) Income Value -------------------------------------------------------------------------------------------------------- Gorman-Rupp Co. 988,195 -- -- 977,075 $206,353 $39,522,684 8. Subsequent Events In preparing these financial statements, PIM has evaluated the impact of all events and transactions for potential recognition or disclosure and has determined that there were no subsequent events requiring recognition or disclosure in the financial statements. 42 Pioneer Equity Income Fund | Semiannual Report | 4/30/11 Approval of Investment Advisory Agreement Pioneer Investment Management, Inc. (PIM) serves as the investment adviser to Pioneer Equity Income Fund (the Fund) pursuant to an investment advisory agreement between PIM and the Fund. In order for PIM to remain the investment adviser of the Fund, the Trustees of the Fund must determine annually whether to renew the investment advisory agreement for the Fund. The contract review process began in March 2010 as the Trustees of the Fund agreed on, among other things, an overall approach and timeline for the process. In July 2010, 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 2010 and September 2010. 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, 2010 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 16, 2010, 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. In addition, the Trustees considered the arrangements put in place to retain key investment and other personnel. The Trustees also considered the substantial attention and high priority given by PIM's senior management to the Pioneer fund complex. Pioneer Equity Income Fund | Semiannual Report | 4/30/11 43 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 first quintile of its Morningstar category for the one year period ended June 30, 2010, in the second quintile of its Morningstar category for the three and five year periods ended June 30, 2010, and in the third quintile of its Morningstar category for the ten year period ended June 30, 2010. (In all quintile rankings referred to throughout this disclosure, first quintile is most favorable to the Fund's shareowners. Thus, highest relative performance would be first quintile and lowest relative expenses would also be first quintile.) The Trustees concluded that the investment performance of the Fund was satisfactory. Management Fee and Expenses The Trustees considered information showing the fees and expenses of the Fund in comparison to the management fees of its peer group of funds as classified by Morningstar and the expense ratios of a peer group of funds selected on the basis of criteria determined by the Independent Trustees for this purpose using data provided by Strategic Insight Mutual 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, 2010 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, 2010 was in the fourth quintile relative to its Strategic Insight peer group for the comparable period. The Trustees noted the impact of the Fund's non-management fee expenses on the Fund's expense ratio. 44 Pioneer Equity Income Fund | Semiannual Report | 4/30/11 The Trustees also reviewed management fees charged by PIM to its institutional and other clients. In evaluating the fees associated with PIM'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 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 recognize that economies of scale are difficult to identify and quantify 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. Pioneer Equity Income Fund | Semiannual Report | 4/30/11 45 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. 46 Pioneer Equity Income Fund | Semiannual Report | 4/30/11 Trustees, Officers and Service Providers Trustees John F.

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.
