This is a welcome relief, and we are generally optimistic about the prospects for the economy going forward. Still, challenges remain. Unemployment is high; consumer demand and loan growth are weak; and housing has not returned to normal. At Pioneer, we have long advocated the benefits of investing for the long term. This strategy has generally performed well for many investors. Those who remained invested in the market during the downturn have most likely seen their portfolios start to recover over the past year, as the Dow Jones Industrial Average climbed back from the depressed levels we saw in early 2009. Many bond investors have similarly seen a strong rebound, with a broad-based recovery occurring across many different fixed-income asset classes. The riskiest asset classes, such as high-yield bonds, outperformed other fixed-income asset classes during most of 2009. At Pioneer, we are not changing the approach to investing that we have used for more than 80 years. We remain focused on company fundamentals and risk management. Our investment process is based on careful research into individual companies, quantitative analysis, and active portfolio management. This three-pillared process, which we apply to each of our portfolios, is supported by an integrated team approach and is designed to carefully balance risk and reward. While we see potential opportunities for making money in many corners of the markets around the globe, it takes research and experience to separate solid investment opportunities from speculation. Following this difficult period, many investors are rethinking their approach to investing and risk management. Some are questioning whether the basic investment principles they were taught in the past are still useful in today's markets. Complicating matters is that financial markets remain unpredictable. 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 | 4/30/10 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 | 4/30/10 3 Portfolio Management Discussion | 4/30/10 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, 2010, and the Fund's performance. Mr. Carey is responsible for the day-to-day management of Pioneer Equity Income Fund. Q Please discuss the investment environment for the fund during the six months ended April 30, 2010. A For the most part, the stock market continued its recovery over the six- month period. There was one fairly sharp "correction" between the middle of January and the middle of February, but overall it was a period of strong performance for stocks. Unlike the "low-quality" rally earlier in 2009, the market after October 31, 2009, was also more balanced, and "higher-quality" stocks, too, did well, which worked in favor of the Pioneer Equity Income Fund's portfolio. Late in the period, though, serious concerns emerged about financial problems in some of the European countries, most particularly Greece, and the possible repercussions for the rest of the global economy. As we write, the market has largely retraced its course since last fall, and market pundits are again sounding gloomy. With the problems in Europe, people are also focusing anew on our own Federal and state budget deficits here in the United States, and on our still-high unemployment. From a "glass half full" outlook, many investors have once more gone to a "glass half empty" outlook. Despite that setback for the market -- which, we should emphasize, began in earnest immediately after the end of the reporting period covered in this letter -- we remain generally optimistic. Certainly the so-called "sovereign debt" worries are legitimate, but we think that the powerful forces of economic recovery should be able to overcome those obstacles. As we talk with the managements of the companies in which we have invested the Fund's assets, we are impressed with the plans for growth that so many of the managements have, as well as with the sound financial condition of most of their companies. Dividends are growing again, and mergers and acquisitions are stimulating interest in the market almost on a daily basis. With many investors still not "back in the market" after the severe market setback of 2008, we are also nowhere near an "overbought" condition. Indeed, if some of those investors restore an allocation to stocks over the next couple of years, they could provide considerable support for stock prices. Right now, though, we are passing through a storm, even if it does, to us, look like a potentially attractive buying opportunity. 4 Pioneer Equity Income Fund | Semiannual Report | 4/30/10 Q How did the Fund perform during the six-month period ended April 30, 2010? A Pioneer Equity Income Fund Class A shares returned 16.38% at net asset value over the six months ended April 30, 2010, compared with a return of 17.77% for the Fund's benchmark, the Russell 1000 Value Index (the Russell Index). Over the same period, the average return of the 302 mutual funds in Lipper's Equity Income category was 13.89%. Q What sector allocations or individual securities added or detracted most from the performance of the Fund over the six months ended April 30, 2010? A Contributing positively to performance were the Fund's underweight in the lagging energy sector and overweights in the performance-leading materials and industrials sectors. On the other hand, the Fund was somewhat underweight the best-performing consumer discretionary sector, and within that sector we had less-than-benchmark exposure to some of the retailing, automotive, and other stocks with especially strong performance. Likewise in the industrial sector, the Fund did not own either General Electric or Boeing, and they both showed good results over the six-month period. The overall effect of the Fund's sector weights and stock selections was a modest underperformance of the benchmark Russell Index. Q The Fund typically has a high regard for dividends. The recession saw many companies cutting their dividends or failing to raise them. Has the rally in the market and the global economic recovery brought improvement in the dividend picture? A Yes, thank goodness, companies have been more generous with dividend payments since the economy turned positive. We are both seeing dividend increases from portfolio holdings and finding numerous, attractive, dividend-paying stocks in the marketplace. There is concern among investors over likely increases in the maximum Federal tax rate on dividends starting in 2011, but we shall face that issue when we have to. For now, companies have been reporting much better earnings in the recovering economy, and many of them are passing along a portion of those earnings to their shareholders. Q What stocks did you add to or remove from the Fund's portfolio over the six months ended April 30, 2010? A During the period, we added nine positions to the Fund's portfolio and liquidated seven. New additions included Helmerich and Payne, sophisticated contract driller of oil and gas wells in North and South America, with special expertise in the land rigs needed to develop new gas reserves in the United States; Lockheed Martin and Northrup Grumman, prominent defense and aerospace companies that we found selling at quite reasonable prices because of what appeared to be misplaced investor anxiety over the Pioneer Equity Income Fund | Semiannual Report | 4/30/10 5 Federal defense budget; Sara Lee, a diversified, worldwide food and consumer products company that appears finally to be achieving greater efficiencies and profitability; and Applied Materials, an out-of-favor but, we think, formidable supplier of semiconductor-manufacturing equipment. Also new to the portfolio were three utilities, Wisconsin Energy, DPL, and National Fuel Gas; and AT&T, a name the Fund has owned in the past. Sold, for a variety of reasons, but generally because we thought either that the stocks had reached fair value or that there were more appealing alternatives, were: Royal Dutch Shell, Caterpillar, Parker Hannifin, McGraw-Hill, Coca-Cola, Kraft Foods, and FirstEnergy. Q What is your outlook for the rest of 2010, and how might that outlook influence your investment approach? A It is too early to tell how the European financial crisis will be resolved and what long-term effects it may have on global markets. We think, again, that the world economy is resilient enough to absorb the stresses resulting from that crisis, but we are of course watching the situation closely. To the extent that stocks sell off in response to news events related to the problems with European sovereign debt and other "macro" issues (North Korea? Iran? Icelandic volcanoes?) rather than fundamental, earnings-related issues, we would be inclined to see buying opportunities, not reasons to sell. Of course the so-called macro events can weigh on companies in the near term and even affect earnings. It has been our observation over many years, however, that well-managed companies can usually find "ways to cope," strategies for success even in trying times. Always it has been our intention to invest the assets of the Fund in companies with good managements -- managements that are astute, honest, forward-looking, adaptable, and shareholder oriented. That will be our goal during the months ahead, and we hope that it will stand the Fund in good stead. Thank you as always for your support.

Investment return and principal value will fluctuate, and shares, when redeemed, may be worth more or less than their original cost. Performance shown 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. The Russell 1000 Value Index measures the performance of large-cap U.S. value stocks. Index returns are calculated monthly, assume reinvestment of dividends and, unlike Fund returns, do not reflect any fees, expenses or sales charges. You cannot invest directly in any index. 14 Pioneer Equity Income Fund | Semiannual Report | 4/30/10 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, 2009 through April 30, 2010. - --------------------------------------------------------------------------------------------------------------------------- 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 11/1/09 - --------------------------------------------------------------------------------------------------------------------------- Ending Account Value $ 1,163.80 $ 1,158.50 $ 1,159.90 $ 1,162.60 $ 1,167.00 $ 1,166.40 (after expenses) on 4/30/10 - --------------------------------------------------------------------------------------------------------------------------- Expenses Paid $ 6.28 $ 11.61 $ 10.55 $ 7.67 $ 3.81 $ 4.24 During Period* - --------------------------------------------------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.17%, 2.17%, 1.97%, 1.43%, 0.71%, and 0.79%, 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). Pioneer Equity Income Fund | Semiannual Report | 4/30/10 15 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 five classes of shares designated as Class A, 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 it 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 this 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 Pioneer Equity Income Fund | Semiannual Report | 4/30/10 35 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, 2010, there were no securities that were valued using fair value methods (other than securities that were valued using prices supplied by independent pricing services). Short-term fixed income securities with remaining maturities of sixty days or less generally are valued at amortized cost. 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. 36 Pioneer Equity Income Fund | Semiannual Report | 4/30/10 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 paid will be determined at the end of the current taxable year. The tax character of distributions paid during the year ended October 31, 2009 was as follows: - --------------------------------------------- 2009 - --------------------------------------------- Distributions paid from: Ordinary income $20,291,330 Long-term capital gain -- - --------------------------------------------- Total $20,291,330 ============================================= The following shows the components of distributable earnings on a federal income tax basis at October 31, 2009: - --------------------------------------------------- 2009 - --------------------------------------------------- Distributable earnings: Undistributed ordinary income $ 451,928 Capital loss carryforward (234,534,494) Unrealized appreciation 142,062,602 - --------------------------------------------------- Total $ (92,019,964) =================================================== The difference between book-basis and tax-basis unrealized appreciation is attributable to the tax basis adjustments on partnerships. C. Fund Shares The Fund records sales and repurchases of its shares as of trade date. Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the Fund and a wholly owned indirect subsidiary of UniCredit S.p.A. Pioneer Equity Income Fund | Semiannual Report | 4/30/10 37 (UniCredit), earned approximately $30,130 in underwriting commissions on the sale of Class A shares during the six months ended April 30, 2010. 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. Shareowners of each class participate in all expenses and fees paid to the transfer agent, Pioneer Investment Management Shareholder Services, Inc. (PIMSS), for its services, which are allocated 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 fair 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 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 38 Pioneer Equity Income Fund | Semiannual Report | 4/30/10 interest on the securities loaned. Gain or loss on the fair value of the loaned securities that may occur during the term of the loan will be for the account of the Fund. The amount of the collateral is required to be adjusted daily to reflect any price fluctuation in the fair value of the loaned securities. If the required market value of the collateral is less than the fair value of the loaned securities, the borrower is required to deliver additional collateral for the account of the Fund prior to the close of the next business 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 year ended April 30, 2010, 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 $16,419 in management fees, administrative costs and certain other reimbursements payable to PIM at April 30, 2010. 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. Pioneer Equity Income Fund | Semiannual Report | 4/30/10 39 For the six months ended April 30, 2010, such out-of-pocket expenses by class of shares were as follows: - --------------------------------------------- Shareholder Communications: - --------------------------------------------- Class A $314,968 Class B 20,006 Class C 48,072 Class R 85,020 Class Y 15,219 Class Z 45 - --------------------------------------------- Total $483,330 ============================================= Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $116,731 in transfer agent fees and out-of-pocket reimbursements payable to PIMSS at April 30, 2010. 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 $9,503 in distribution fees payable to PFD at April 30, 2010. 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 reimbursement for actual expenditures. 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. 40 Pioneer Equity Income Fund | Semiannual Report | 4/30/10 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, 2010, CDSCs in the amount of $30,614 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, 2010, 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, 2010, 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, 2010: - ------------------------------------------------------------------------------------------------------- Beginning Corporate Ending Balance Purchases Actions Balance Dividend Affiliates (shares) (shares) (shares) (shares) Income Value - ------------------------------------------------------------------------------------------------------- Gorman-Rupp Co. 988,195 -- -- 988,195 $207,521 $27,560,759 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. Pioneer Equity Income Fund | Semiannual Report | 4/30/10 41 Approval of Investment Advisory Agreement (unaudited) 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 2009 as the Trustees of the Fund agreed on, among other things, an overall approach and timeline for the process. In July 2009, 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 August 2009. After reviewing and discussing the materials, the Trustees submitted a request for additional information to PIM in September 2009, 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, 2009 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 10, 2009, 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. 42 Pioneer Equity Income Fund | Semiannual Report | 4/30/10 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 fifth quintile of its Morningstar category for the one year period ended June 30, 2009, in the third quintile of its Morningstar category for the three and ten year periods ended June 30, 2009 and in the second quintile of its Morningstar category for the five year period ended June 30, 2009. (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 reasons for the Fund's recent underperformance with PIM in view of the Fund's investment approach and the market conditions present during the relevant periods, and were satisfied with the information presented by PIM with respect to the Fund's performance. Management Fee and Expenses The Trustees considered information showing the fees and expenses of the Fund in comparison to the management fees 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, 2009 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 that the Fund's expense ratio for the twelve months ended June 30, 2009 was in the second quintile relative to its Pioneer Equity Income Fund | Semiannual Report | 4/30/10 43 Strategic Insight peer group for the comparable period. The Trustees considered the breakpoint in the management fee schedule and the reduced fee rate on assets over $10 billion. 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. The Trustees also concluded that the Fund's expense ratio was reasonable taking into account the nature and quality of 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 difficult year in 2008 for financial markets, as the 44 Pioneer Equity Income Fund | Semiannual Report | 4/30/10 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.

N/A (f) If greater than 50 percent, disclose the percentage of hours expended on the principal accountant's engagement to audit the registrant's financial statements for the most recent fiscal year that were attributed to work performed by persons other than the principal accountant's full-time, permanent employees.
