All year, investors focused on the Federal Reserve System's (the Fed's) deliberations over when to begin normalizing interest rates. However, while there were signs of gradual economic improvement in the U.S., economies abroad increasingly diverged. In June, for example, investors grew concerned about the debt crisis in Greece. That news, in turn, was followed by evidence of an economic slowdown in China, which only served to exacerbate existing worries about growth trends in the emerging markets, a segment of the global economy already being negatively impacted by slumping commodity prices, including the price of crude oil, which has been in near-steady decline for almost a year. Through September 30, 2015, the pockets of heightened market volatility alluded to above had resulted in the Standard & Poor's 500 Index turning in a negative (-5.27%) return over the first nine months of the year. However, the S&P 500 recovered nicely in October, returning 8.43% for the month, which boosted the index's year-to-date return into positive territory, at 2.71%. Despite the headwinds still vexing the global economy, our longer-term view of the U.S. economy has remained positive. Economic conditions in the U.S. have generally been constructive, based largely on improvements in employment statistics and an uptick in the housing sector, which has aided the consumer side of the economy, where household spending has been rising modestly. U.S. consumers also stand to benefit, potentially, from lower energy prices as the winter weather approaches. We continue to believe the U.S. economy remains on a slow, steady growth trend, and that it is unlikely to be disrupted by a slow pace of interest-rate normalization by the Fed. Pioneer Investments believes that investors in today's environment can potentially benefit from the consistent and disciplined investment approach we have used since our founding in 1928. We focus on identifying value across global markets using proprietary research, careful risk management, and a long-term perspective. Our ongoing goal is to produce compelling returns consistent with the stated objectives of our investment products, and with our shareowners' expectations. We believe our shareowners can benefit from the experience and tenure of our investment teams as well as the insights generated from our extensive research process. 2 Pioneer Equity Income Fund | Annual Report | 10/31/15 As always, and particularly during times of market uncertainty, we encourage you to work with your financial advisor to develop an overall investment plan that addresses both your short- and long-term goals, and to implement such a plan in a disciplined manner. We greatly appreciate your trust in us in the past and look forward to continuing to serve you in the future. Sincerely, /s/ Lisa M. Jones Lisa M.

Pioneer Equity Income Fund | Annual Report | 10/31/15 3 Portfolio Management Discussion | 10/31/15 In the following interview, John Carey, Executive Vice President and Director of U.S. Portfolio Management at Pioneer Investments, discusses the investment environment during the 12-month period ended October 31, 2015, and Pioneer Equity Income Fund's performance during the period. Mr. Carey is responsible for the day-to-day management of Pioneer Equity Income Fund, along with Walter Hunnewell, Jr., a vice president and a portfolio manager at Pioneer. Q How would you describe the market environment for equities during the 12-month period ended October 31, 2015, particularly for the types of equities deemed appropriate for the Fund? A Returns for the overall equity market were positive for the 12-month period. Within the market, however, growth stocks significantly outperformed value stocks, as investors were drawn to stocks of companies that appeared able to achieve higher earnings in an economy expanding at only a moderate pace. Throughout the period there was a market expectation, not fulfilled, that the Federal Reserve System (the Fed) would raise short-term interest rates, and a resulting cautiousness towards stocks in sectors and industries felt to be vulnerable to higher rates, including utilities, real-estate investment trusts (REITs), and industrials, among others. The strong U.S. dollar - strong to a degree because of that belief that rates were going higher - hampered business for many exporting companies, particularly machinery manufacturers and consumer-products makers. Finally, an intense fascination with the internet, online sales, biotech, and other "cutting-edge" enterprises drained investment dollars from more "old-line"-type businesses and led to quite strong performance by a select list of hyper-growth "stories;" and plodding, sluggish performance by many other stocks. In that "Tale of Two Cities" stock market environment, the approach that we took in managing the Fund was our customary one of emphasizing stocks we thought well supported by both attractive valuation and appreciation potential. The strategy of Pioneer Equity Income Fund is to "back into growth" by looking first at a company's record of dividend* payments. We place special emphasis on owning stocks that have paid dividends over multiple years and at rising levels. We seek to own shares of companies able to achieve such track records as the result of steady and growing earnings and cash flows. We also look for stocks that have not received as much attention as market-leading names - and that sometimes positions the Fund in stocks not yet fully priced. One * Dividends are not guaranteed. 4 Pioneer Equity Income Fund | Annual Report | 10/31/15 byproduct of that process is our happening upon stocks that, from time to time, are "taken over" by other entities in mergers and acquisitions, often at premium prices relative to the current market. Kraft (consumer staples) and Chubb (financials) were two significant portfolio holdings that received such offers during the 12-month period, with both contributing positively to the Fund's investment results. Q How did the Fund perform in that environment during the 12-month period ended October 31, 2015? A Pioneer Equity Income Fund's Class A shares returned 5.30% at net asset value during the 12-month period ended October 31, 2015, while the Fund's benchmark, the Russell 1000 Value Index (the Russell Index), returned 0.53%. During the same period, the average return of the 497 mutual funds in Lipper's Equity Income Funds category was 0.08%, and the average return of the 1,377 mutual funds in Morningstar's Large Value Funds category was 0.37%. Q The Fund outperformed the Russell Index benchmark during the 12-month period ended October 31, 2015. Could you please discuss the major reasons for the Fund's benchmark-relative outperformance? A Most of the benchmark-relative outperformance in the Fund's portfolio during the period came from stock selections, but sector allocations also contributed positively to relative returns. The main sector-allocation contributing factor was the Fund's large underweight to energy, the poorest-performing sector in the Russell Index during the period. With regard to energy, we were skeptical that oil and gas prices would bounce back quickly from the nosedive they took after the middle of the 2014 calendar year, and we were also concerned about the sustainability of dividend payments in a sector with plummeting earnings. On the negative side of asset allocation, a portfolio overweight to the likewise poor-performing materials sector hurt relative results, but stock selection in the sector was good, nearly offsetting the performance loss from the sector-weighting decision. The bulk of the Fund's strong benchmark-relative performance during the period resulted from gains on individual stocks held in the portfolio. We have already mentioned Kraft and Chubb, recipients of take-over offers. Other meaningful, positive performance attribution came from the Fund's holdings in Dr. Pepper Snapple (consumer staples), Cedar Fair (consumer discretionary), Mondelez International (consumer staples), NVIDIA (information technology), and Pinnacle Foods (consumer staples). The Pioneer Equity Income Fund | Annual Report | 10/31/15 5 Fund's returns also benefited from not owning, or owning only relatively modest amounts of, performance laggards such as Chevron, ExxonMobil, and Wal-Mart Stores. Security selection results were not all positive during the 12-month period, however, as the Fund lost some benchmark-relative performance on positions in Canadian Imperial Bank (financials) and Syngenta (materials). The problems plaguing the natural-resources industries affected the Canadian economy and diminished prospects for growth in the banking industry, and so we sold the Fund's position in Canadian Imperial during the period. Syngenta received, but spurned, a rich acquisition offer from Monsanto, which ultimately pulled its offer and walked away, causing a decline in Syngenta's share price. We have retained the Fund's position in Syngenta as we think the shares, at their reduced price, represent reasonable value. Q What changes did you make to the Fund's portfolio during the 12-month period ended October 31, 2015? A During the 12-month period, we added somewhat more than two dozen positions to the Fund's portfolio and liquidated nearly three dozen, with a net reduction of about a half-dozen names. Important additions to the portfolio during the period included: Consolidated Edison (utilities), an electricity and natural-gas supplier to New York City and parts of New Jersey and Pennsylvania; Helmerich & Payne (energy), an oil-and-gas drilling company, with a focus on North and South America; Mead Johnson Nutrition (consumer staples), provider of nutritional products to babies, with important businesses in emerging markets, especially China; CBS (consumer discretionary), television and radio broadcaster and book publisher; and Hartford Financial Services (financials), diversified insurance underwriter. Later in the period, after observing the stock's decline with the price of oil, we took advantage of what we regarded as an attractive entry point and added shares of Chevron (energy), the integrated, international oil, gas, and chemical company we mentioned previously. Both purchased and sold during the period was Broadcom (information technology), developer of integrated circuits for communications. The stock jumped after we purchased it, when the company received a premium take- over bid, and we decided to take profits and reinvest elsewhere. AGL Resources (utilities) likewise received a take-over bid, leading us to sell that position. With regard to Kraft, we kept the Fund invested in the stock through its merger with Heinz and later sold the portfolio's holding in the combined company. A host of other sales from the portfolio during the period owed to our thinking that the price of the stock had reached fair 6 Pioneer Equity Income Fund | Annual Report | 10/31/15 value, that earnings prospects for the company had diminished or that we had found better value in other stocks and determined that a substitution of names was warranted. Q Did the Fund hold any derivatives during the 12-month period ended October 31, 2015? A No. The Fund did not own any derivative positions during the period. Q As you noted earlier, the Fund typically places an emphasis on dividend- paying stocks. Would you describe the environment for dividends as positive or negative during the 12-month period ended October 31, 2015? A Generally speaking, investors were cautious towards owning stocks whose prices they perceived as receiving meaningful support from their dividend yields. Due to the broad expectation that interest rates were soon going to rise, investors especially shied away from names they regarded as "bond substitutes." While we understand the logic of that view; namely, that bonds offering high coupons will present greater competition to stocks trading on their dividend yields, we have never quite agreed with it. As long as companies can increase earnings over time and thus potentially increase their dividends, they stand a chance of competing for investor attention with bonds, which usually have fixed coupon rates from issuance through maturity. Later in the period, when we thought that weakness in some of the so-called bond substitutes presented potentially attractive buying opportunities, we added to the Fund's holdings in utilities and REITs, among other income-heavy securities. In the event, of course, the Fed had still not raised short-term rates by the end of the period, and the above-noted investor concerns appeared to become less intense. Q What is your outlook for the equity markets as we approach the end of calendar 2015 and get ready to usher in a new calendar year? A Investor behavior seems much influenced by the state of the economy, and so we, too, think about that, even while spending most of our time studying and assessing companies. Our view is that the U. S. economy will show continued moderate growth into 2016, but with risks. The weakness in commodities prices troubles us, as do the soft results for many industrials sector names, especially the capital-goods companies. So far, the housing and automotive industries are holding up; but, especially in the case of autos, one has the sense that promotions and "special offers" are becoming more important. Merger-and-acquisition activity, which helped fuel market advances over the past couple of years and certainly has benefited the Fund's performance, has lost some of its traction as anti-trust cases have become more aggressive and opposition has grown to tax-inversion Pioneer Equity Income Fund | Annual Report | 10/31/15 7 schemes. In our opinion, it is very difficult to see higher profit margins at this point without stronger sales; and, particularly for multinational companies, the strong U.S. dollar and the weakness of economies elsewhere in the world are holding sales back. Another key question is what will happen going forward in Europe, Latin America, and China? We believe we need to see improvement in those areas, along with some lessening of the current and rather acute geopolitical risks, if we are to experience markedly higher economic growth in the U.S. Therefore, we are cautious, if still on balance constructive, regarding economic prospects here at home. Against that backdrop, we think that the Fund's strategy of leaning towards value and dividends as well as balance- sheet strength - and company management teams committed to returns for shareholders - remains the way to go.

Pioneer Equity Income Fund | Annual Report | 10/31/15 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 May 1, 2015, through October 31, 2015. ------------------------------------------------------------------------------------- Share Class A C K R Y ------------------------------------------------------------------------------------- Beginning Account $1,000.00 $1,000.00 $1,000.00 $1,000.00 $1,000.00 Value on 5/1/15 ------------------------------------------------------------------------------------- Ending Account Value $1,010.94 $1,007.23 $1,013.04 $1,009.04 $1,012.37 (after expenses) on 10/31/15 ------------------------------------------------------------------------------------- Expenses Paid $ 5.37 $ 9.11 $ 3.40 $ 7.14 $ 3.96 During Period* ------------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.06%, 1.80%, 0.67% 1.41% and 0.78% for Class A, Class C, Class K, Class R and Class Y shares, respectively, multiplied by the average account value over the period, multiplied by 184/365 (to reflect the one-half year period). 16 Pioneer Equity Income Fund | Annual Report | 10/31/15 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. Expenses Paid on a $1,000 Investment in Pioneer Equity Income Fund Based on a hypothetical 5% return per year before expenses, reflecting the period from May 1, 2015, through October 31, 2015. ------------------------------------------------------------------------------------- Share Class A C K R Y ------------------------------------------------------------------------------------- Beginning Account $1,000.00 $1,000.00 $1,000.00 $1,000.00 $1,000.00 Value on 5/1/15 ------------------------------------------------------------------------------------- Ending Account Value $1,019.86 $1,016.13 $1,021.83 $1,018.10 $1,021.27 (after expenses) on 10/31/15 ------------------------------------------------------------------------------------- Expenses Paid $ 5.40 $ 9.15 $ 3.41 $ 7.17 $ 3.97 During Period* ------------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.06%, 1.80%, 0.67% 1.41% and 0.78% for Class A, Class C, Class K, Class R and Class Y shares, respectively, multiplied by the average account value over the period, multiplied by 184/365 (to reflect the one-half year period).

The Fund offers five classes of shares designated as Class A, Class C, Class K, Class R and Class Y shares. Class B shares converted to Class A shares as of the close of business on November 10, 2014. Class Z shares were converted to Class Y shares as of the close of business on August 7, 2015. 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 of Trustees the flexibility to specify either per-share voting or dollar-weighted voting when submitting matters for shareholder approval. Under per-share voting, each share of a class of the Fund is entitled to one vote. Under dollar-weighted voting, a shareholder's voting power is determined not by the number of shares owned, but by the dollar value of the shares on the record date. Each share class has exclusive voting rights with respect to matters affecting only that class, including with respect to the distribution plan for that class. There is no distribution plan for Class K or Class Y shares. The Fund's financial statements have been prepared in conformity with U.S. generally accepted accounting principles that require the management of the Fund to, among other things, make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income, expenses and gains and losses on investments during the reporting period. Actual results could differ from those estimates. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements: 34 Pioneer Equity Income Fund | Annual Report | 10/31/15 A. Security Valuation Security transactions are recorded as of trade date. The net asset value of the Fund is computed once daily, on each day the New York Stock Exchange (NYSE) is open, as of the close of regular trading on the NYSE. In computing the net asset value, securities that have traded on an exchange are valued at the last sale price on the principal exchange where they are traded. Securities that have not traded on the date of valuation, or securities for which sale prices are not available, generally are valued at the mean between the last bid and asked prices. Shares of money market mutual funds are valued at such funds' net asset value. Cash may include overnight time deposits at approved financial institutions. Trading in foreign securities is substantially completed each day at various times prior to the close of the NYSE. The values of such securities used in computing the net asset value of the Fund's shares are determined as of such times. Securities for which independent pricing services are unable to supply prices or for which market prices and/or quotations are not readily available or are considered to be unreliable are valued by a fair valuation team comprised of certain personnel of Pioneer Investment Management, Inc., (PIM), the Fund's investment adviser, pursuant to procedures adopted by the Fund's Board of Trustees. PIM's fair valuation team uses fair value methods approved by the Valuation Committee of the Board of Trustees. PIM's fair valuation team is responsible for monitoring developments that may impact fair valued securities and for discussing and assessing fair values on an ongoing basis, and at least quarterly, with the Valuation Committee of the Board of Trustees. Inputs used when applying fair value methods to value a security may include credit ratings, the financial condition of the company, current market conditions and comparable securities. The Fund may use fair value methods if it is determined that a significant event has occurred after the close of the exchange or market on which the security trades and prior to the determination of the Fund's net asset value. Examples of a significant event might include political or economic news, corporate restructurings, natural disasters, terrorist activity or trading halts. Thus, the valuation of the Fund's securities may differ significantly from exchange prices and such differences could be material. At October 31, 2015, there were no securities that were valued using fair value methods (other than securities that were valued using prices supplied by independent pricing services or broker-dealers). Pioneer Equity Income Fund | Annual Report | 10/31/15 35 B. Investment Income and Transactions Dividend income is recorded on the ex-dividend date, except that certain dividends from foreign securities where the ex-dividend date may have passed are recorded as soon as the Fund becomes aware of the ex-dividend data in the exercise of reasonable diligence. Interest income, including interest on income bearing cash accounts, is recorded on the accrual basis. Dividend and interest income are reported net of unrecoverable foreign taxes withheld at the applicable country rates. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. C. Federal Income Taxes It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its net taxable income and net realized capital gains, if any, to its shareowners. Therefore, no federal income tax provision is required. As of October 31, 2015, the Fund did not accrue any interest or penalties with respect to unrecognized tax positions, which, if applicable, would be recorded as an income tax expense in the Statement of Operations. Tax returns filed within the prior three years are subject to examination by Federal and State tax authorities. The amount and character of income and capital gain distributions to shareowners are determined in accordance with federal income tax rules, which may differ from U.S. generally accepted accounting principles. Distributions in excess of net investment income or net realized gains are temporary overdistributions for financial statement purposes resulting from differences in the recognition or classification of income or distributions for financial statement and tax purposes. Capital accounts within the financial statements are adjusted for permanent book/tax differences to reflect tax character, but are not adjusted for temporary differences. At October 31, 2015, the Fund reclassified $267,833 to decrease undistributed net investment income and $267,833 to increase accumulated net realized gain on investments to reflect permanent book/tax differences. These adjustments have no impact on net assets or the results of operations. The tax character of distributions during the year ended October 31, 2015, and October 31, 2014, was as follows: --------------------------------------------------------------------------- 2015 2014 --------------------------------------------------------------------------- Distributions paid from: Ordinary income $ 33,166,428 $34,882,719 Long-term capital gain 128,314,155 49,279,841 --------------------------------------------------------------------------- Total $161,480,583 $84,162,560 =========================================================================== 36 Pioneer Equity Income Fund | Annual Report | 10/31/15 The following shows the components of distributable earnings on a federal income tax basis at October 31, 2015: --------------------------------------------------------------------------- 2015 --------------------------------------------------------------------------- Distributable earnings: Undistributed ordinary income $ 1,546,368 Undistributed long term capital gain 110,273,182 Net unrealized appreciation 386,959,818 --------------------------------------------------------------------------- Total $498,779,368 =========================================================================== The difference between book-basis and tax-basis net unrealized appreciation is attributable to the tax deferral of losses on wash sales and tax basis adjustments on Real Estate Investment Trust (REIT) holdings and partnerships. D. Fund Shares The Fund records sales and repurchases of its shares as of trade date. Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the Fund and a wholly owned indirect subsidiary of UniCredit S.p.A. (UniCredit), earned $77,483 in underwriting commissions on the sale of Class A shares during the year ended October 31, 2015. E. Class Allocations Income, common expenses and realized and unrealized gains and losses are calculated at the Fund level and allocated daily to each class of shares based on its respective percentage of adjusted net assets at the beginning of the day. Distribution fees are calculated based on the average daily net asset value attributable to Class A, Class C and Class R shares of the Fund, respectively (see Note 4). Class K and Class Y shares do not pay distribution fees. All expenses and fees paid to the Fund's transfer agent, for its services are allocated among the classes of shares based on the number of accounts in each class and the ratable allocation of related out-of-pocket expenses (see Note 3). Distributions to shareowners are recorded as of the ex-dividend date. Distributions paid by the Fund with respect to each class of shares are calculated in the same manner and at the same time, except that net investment income dividends to Class A, Class C, Class K, Class R and Class Y shares can reflect different transfer agent and distribution expense rates. Pioneer Equity Income Fund | Annual Report | 10/31/15 37 F. Risks At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making the Fund more susceptible to any economic, political or regulatory developments or other risks affecting those industries or sectors. The Fund's prospectus contains unaudited information regarding the Fund's principal risks. Please refer to that document when considering the Fund's principal risks. G. Forward Foreign Currency Contracts The Fund may enter into forward foreign currency contracts (contracts) for the purchase or sale of a specific foreign currency at a fixed price on a future date. All contracts are marked to market daily at the applicable exchange rates, and any resulting unrealized appreciation or depreciation is recorded in the Fund's financial statements. The Fund records realized gains and losses at the time a contract is offset by entry into a closing transaction or extinguished by delivery of the currency. Risks may arise upon entering into these contracts from the potential inability of counterparties to meet the terms of the contract and from unanticipated movements in the value of foreign currencies relative to the U.S. dollar (see Note 8). 2. Management Agreement PIM, a wholly owned indirect subsidiary of UniCredit, manages the Fund's portfolio. Management fees are calculated daily at the annual rate of 0.60% of the Fund's average daily net assets up to $10 billion and 0.575% on assets over $10 billion. For the year ended October 31, 2015, the effective management fee (excluding waivers and/or assumption of expenses) was equivalent to 0.60% of the Fund's average daily net assets. In addition, under the management and administration agreements, certain other services and costs, including accounting, regulatory reporting, and insurance premiums, are paid by the Fund as administrative reimbursements. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $72,818, in management fees, administrative costs and certain other reimbursements payable to PIM at October 31, 2015. 3. Transfer Agent Pioneer Investment Management Shareholder Services, Inc. (PIMSS), a wholly owned indirect subsidiary of UniCredit, provided substantially all transfer agent and shareowner services to the Fund at negotiated rates. In addition, the Fund reimbursed 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. 38 Pioneer Equity Income Fund | Annual Report | 10/31/15 For the year ended October 31, 2015, such out-of-pocket expenses by class of shares were as follows: -------------------------------------------------------------------------------- Shareholder Communications: -------------------------------------------------------------------------------- Class A $ 662,235 Class B 607 Class C 118,250 Class K 396 Class R 187,800 Class Y 621,602 Class Z 1,759 -------------------------------------------------------------------------------- Total $1,592,649 ================================================================================ Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $394,079 in transfer agent fees and out-of-pocket reimbursements payable to PIMSS at October 31, 2015. 4. Distribution and Service Plans The Fund has adopted a Distribution Plan pursuant to Rule 12b-1 of the Investment Company Act of 1940 with respect to its Class A, Class C and Class R shares. Pursuant to the Plan, the Fund pays PFD 0.25% of the average daily net assets attributable to Class A shares as compensation for personal services and/or account maintenance services or distribution services with regard to Class A shares. Pursuant to the Plan, the Fund also pays PFD 1.00% of the average daily net assets attributable to Class C shares. The fee for Class C shares consists of a 0.25% service fee and a 0.75% distribution fee paid as compensation for personal services and/or account maintenance services or distribution services with regard to Class C shares. Pursuant to the Plan, the Fund further pays PFD 0.50% of the average daily net assets attributable to Class R shares for distribution services. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $28,948 in distribution fees payable to PFD at October 31, 2015. The Fund also has adopted a separate service plan for Class R shares (Service Plan). The Service Plan authorizes the Fund to pay securities dealers, plan administrators or other service organizations that agree to provide certain services to retirement plans or plan participants holding shares of the Fund a service fee of up to 0.25% of the Fund's average daily net assets attributable to Class R shares held by such plans. In addition, redemptions of each class of shares (except Class K, Class R and Class Y shares) may be subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may be imposed on redemptions of certain net asset value purchases of Class A shares within 12 months of purchase. Redemptions of Class C shares within 12 months of purchase are subject to a CDSC of 1.00%, based on the lower of cost or market value of shares being redeemed. Shares Pioneer Equity Income Fund | Annual Report | 10/31/15 39 purchased as part of an exchange remain subject to any CDSC that applied to the original purchase of those shares. There is no CDSC for Class K, Class R or Class Y shares. Proceeds from the CDSCs are paid to PFD. For the year ended October 31, 2015, CDSCs in the amount of $5,329 were paid to PFD. 5. Expense Offset Arrangements The Fund entered into certain expense offset arrangements with PIMSS which may result in a reduction in the Fund's total expenses due to interest earned on cash held by PIMSS. For the year ended October 31, 2015, the Fund's expenses were not reduced under such arrangements. 6. Line of Credit Facility The Fund, along with certain other funds in the Pioneer Family of Funds (the Funds), participates in a committed, unsecured revolving line of credit facility. Borrowings are used solely for temporary or emergency purposes. The Fund may borrow up to the lesser of the amount available under the facility or the limits set for borrowing by the Fund's prospectus and the 1940 Act. The credit facility in effect until June 9, 2015, was in the amount of $215 million. As of June 9, 2015, the facility is in the amount of $240 million. Under such facility, depending on the type of loan, interest on borrowings is payable at the London Interbank Offered Rate (LIBOR) plus 0.85% on an annualized basis, or the Alternate Base Rate, which is the greater of (a) the facility's administrative agent's daily announced prime rate on the borrowing date, (b) 2% plus the Federal Funds Rate on the borrowing date and (c) 2% plus the overnight Eurodollar rate on the borrowing date. The Funds pay an annual commitment fee to participate in a credit facility. The commitment fee is allocated among participating Funds based on an allocation schedule set forth in the credit agreement. For the year ended October 31, 2015, the Fund had no borrowings under the credit facility. 7. Affiliated Companies The Fund's investments in certain companies may exceed 5% of the outstanding voting stock of those companies. Such companies are deemed affiliates of the Fund for financial reporting purposes. The following summarizes transactions with affiliates of the Fund for the year ended October 31, 2015: -------------------------------------------------------------------------------------------------------------- Beginning Corporate Balance Purchases Sales Actions Ending Dividend Realized Affiliates (shares) (shares) (shares) (shares) (shares) Income Value Gain -------------------------------------------------------------------------------------------------------------- The Gorman- Rupp Co. 1,433,678 -- (70,315) -- 1,363,363 $552,377 $38,978,548 $1,843,271 40 Pioneer Equity Income Fund | Annual Report | 10/31/15 8. Forward Foreign Currency Contracts During the year ended October 31, 2015, the Fund had entered into various forward foreign currency contracts that obligate the Fund to deliver or take delivery of currencies at specified future maturity dates. Alternatively, prior to the settlement date of a forward foreign currency contract, the Fund may close out such contract by entering into an offsetting contract. The average value of contracts open during the year ended October 31, 2015 was $788,895. There were no open forward foreign currency contracts at October 31, 2015. 9. Additional Disclosures about Derivative Instruments and Hedging Activities: The Fund's use of derivatives subjects it to the following risks: Interest rate risk relates to the fluctuations in the value of interest-bearing securities due to changes in the prevailing levels of market interest rates. Credit risk relates to the ability of the issuer of a financial instrument to make further principal or interest payments on an obligation or commitment that it has to the Fund. Foreign exchange rate risk relates to fluctuations in the value of an asset or liability due to changes in currency exchange rates. Equity risk relates to the fluctuations in the value of financial instruments as a result of changes in market prices (other than those arising from interest rate risk or foreign exchange risk), whether caused by factors specific to an individual investment, its issuer, or all factors affecting all instruments traded in a market or market segment. Commodity risk relates to the risk that the value of a commodity or commodity index will fluctuate based on increases or decreases in the commodities market and factors specific to a particular industry or commodity. The effect of derivative instruments (not considered to be hedging instruments for accounting disclosure purposes) on the Statement of Operations by risk exposure at October 31, 2015 was as follows: ------------------------------------------------------------------------------------- Statement of Operations Foreign Interest Credit Exchange Equity Commodity Rate Risk Risk Risk Risk Risk ------------------------------------------------------------------------------------- Net realized gain (loss) on Forward foreign currency contracts $ -- $ -- $(139,669) $ -- $ -- ------------------------------------------------------------------------------------- Total Value $ -- $ -- $(139,669) $ -- $ -- ===================================================================================== Pioneer Equity Income Fund | Annual Report | 10/31/15 41 10. Conversion of Class B and Class Z Shares As of the close of business on November 10, 2014, all outstanding Class B shares of the Fund were converted to Class A shares. As of the close of business on August 7, 2015, all outstanding Class Z shares of the Fund were converted to Class Y shares. 42 Pioneer Equity Income Fund | Annual Report | 10/31/15 Report of Independent Registered Public Accounting Firm To the Board of Trustees and the Shareowners of Pioneer Equity Income Fund: -------------------------------------------------------------------------------- We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Pioneer Equity Income Fund as of October 31, 2015, and the related statement of operations for the year then ended and the statements of changes in net assets and the financial highlights for each of the two years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. The financial highlights for the years ended October 31, 2013, 2012, and 2011 were audited by other auditors. Those auditors expressed an unqualified opinion on those financial statements and financial highlights in their report dated December 23, 2013. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of October 31, 2015, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Pioneer Equity Income Fund as of October 31, 2015, and the results of its operations for the year then ended, and the changes in its net assets and the financial highlights for each of the two years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. /s/ Deloiette & Touche LLP Boston, Massachusetts December 23, 2015 Pioneer Equity Income Fund | Annual Report | 10/31/15 43 ADDITIONAL INFORMATION (unaudited) For the year ended October 31, 2015, certain dividends paid by the Fund may be subject to a maximum tax rate of 15%, as provided for by the Jobs and Growth Tax Relief Reconciliation Act (the Act) of 2003. The Fund intends to designate up to the maximum amount of such dividends allowable under the Act, as taxed at a maximum rate of 15%. Complete information will be computed and reported in conjunction with your 2015 form 1099-DIV. The qualifying percentage of the Fund's ordinary income dividends for the purpose of the corporate dividends received deduction was 100%. PIM, the Fund's investment adviser, is currently an indirect, wholly owned subsidiary of UniCredit. On November 11, 2015, UniCredit announced that it signed a binding master agreement with Banco Santander and affiliates of Warburg Pincus and General Atlantic (the "Private Equity Firms") with respect to Pioneer Investments ("Pioneer") and Santander Asset Management ("SAM") (the "Transaction"). The Transaction, as previously announced by UniCredit, will establish a holding company, with the name Pioneer Investments, to be owned by UniCredit (50%) and the Private Equity Firms (50% between them). The holding company will control Pioneer's U.S. operations, including the Adviser. The holding company also will own 66.7% of Pioneer's and SAM's combined operations outside the U.S., while Banco Santander will own directly the remaining 33.3% stake. The closing of the Transaction is expected to happen in 2016, subject to certain regulatory and other approvals. Under the Investment Company Act of 1940, completion of the Transaction will cause the Fund's current investment advisory agreement with PIM to terminate. Accordingly, the Fund's Board of Trustees will be asked to approve a new investment advisory agreement. If approved by the Board, the Fund's new investment advisory agreement will be submitted to the shareholders of the Fund for their approval. Subsequent Event (unaudited) Effective November 2, 2015, Boston Financial Data Service became the transfer agent to the Fund at negotiated rates. 44 Pioneer Equity Income Fund | Annual Report | 10/31/15 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 January 2015 as the Trustees of the Fund agreed on, among other things, an overall approach and timeline for the process. Contract review materials were provided to the Trustees in March 2015 and July 2015. Supplemental contract review materials were provided to the Trustees in September 2015. In addition, the Trustees reviewed and discussed the Fund's performance at regularly scheduled meetings throughout the year and took into account other information related to the Fund provided to the Trustees at regularly scheduled meetings in connection with the review of the Fund's investment advisory agreement. In March 2015, the Trustees, among other things, discussed the memorandum provided by Fund counsel that summarized the legal standards and other considerations that are relevant to the Trustees in their deliberations regarding the renewal of the investment advisory agreement, and reviewed and discussed the qualifications of the investment management teams, as well as the level of investment by the Fund's portfolio managers in the Fund. In July 2015, the Trustees, among other things, reviewed the Fund's management fee and total expense ratios, the financial statements of PIM and its parent companies, the profitability analyses provided by PIM, and possible economies of scale. The Trustees also reviewed the profitability of the institutional business of PIM and PIM's affiliate, Pioneer Institutional Asset Management, Inc. (together with PIM, "Pioneer"), as compared to that of PIM's fund management business, and considered the differences between the fees and expenses of the Fund and the fees and expenses of Pioneer's institutional accounts, as well as the different services provided by PIM to the Fund and by Pioneer to the institutional accounts. The Trustees further considered contract review materials in September 2015. At a meeting held on September 15, 2015, 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 approving 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. Pioneer Equity Income Fund | Annual Report | 10/31/15 45 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 also reviewed PIM's investment approach for the Fund and its research process. The Trustees considered the resources of PIM and the personnel of PIM who provide investment management services to the Fund. They also reviewed the amount of non-Fund assets managed by the portfolio managers of the Fund. The Trustees considered the non-investment resources and personnel of PIM involved in PIM's services to the Fund, including PIM's compliance and legal resources and personnel. The Trustees noted the substantial attention and high priority given by PIM's senior management to the Pioneer fund complex. The Trustees considered that PIM supervises and monitors the performance of the Fund's service providers and provides the Fund with personnel (including Fund officers) and other resources that are necessary for the Fund's business management and operations. The Trustees also considered that, as administrator, PIM is responsible for the administration of the Fund's business and other affairs. The Trustees considered the fees paid to PIM for the provision of administration services. Based on these considerations, the Trustees concluded that the nature, extent and quality of services that had been provided by PIM to the Fund were satisfactory and consistent with the terms of the investment advisory agreement. Performance of the Fund In considering the Fund's performance, the Trustees regularly review and discuss throughout the year data prepared by PIM and information comparing the Fund's performance with the performance of its peer group of funds as classified by each of Morningstar, Inc. (Morningstar) and Lipper, and with the performance of the Fund's benchmark index. They also discuss the Fund's performance with PIM on a regular basis. The Trustees' regular reviews and discussions were factored into the Trustees' deliberations concerning the renewal of the advisory agreement. Management Fee and Expenses The Trustees considered information showing the fees and expenses of the Fund in comparison to the management fees and expense ratios of its peer group of funds as classified by Morningstar and also to the expense ratios of a peer group of funds selected on the basis of criteria determined by the Independent Trustees for this purpose using data provided by Strategic Insight 46 Pioneer Equity Income Fund | Annual Report | 10/31/15 Mutual Fund Research and Consulting, LLC (Strategic Insight), an independent third party. In all quintile rankings referred to below, first quintile is most favorable to the Fund's shareowners. The Trustees considered that the Fund's management fee for the most recent fiscal year was in the second quintile relative to the management fees paid by other funds in its Morningstar peer group for the comparable period. The Trustees also considered the breakpoint in the management fee schedule and the reduced fee rate above a certain asset level. The Trustees considered that the expense ratio of the Fund's Class A shares for the most recent fiscal year was in the third quintile relative to its Morningstar peer group and in the third quintile relative its Strategic Insight peer group, in each case for the comparable period. The Trustees considered the impact of transfer agency, sub-transfer agency, and other non-management fee expenses on the expense ratios of the Fund. The Trustees noted that they separately review the Fund's transfer agency, sub-transfer agency and intermediary arrangements. The Trustees reviewed management fees charged by Pioneer to institutional and other clients, including publicly offered European funds sponsored by affiliates of Pioneer, unaffiliated U.S. registered investment companies (in a sub-advisory capacity), and unaffiliated foreign and domestic separate accounts. The Trustees also considered PIM's costs in providing services to the Fund and Pioneer's costs in providing services to the other clients and considered the differences in management fees and profit margins for Fund and non-Fund services. In evaluating the fees associated with Pioneer's client accounts, the Trustees took into account the respective demands, resources and complexity associated with the Fund and client accounts. The Trustees noted that, in some instances, the fee rates for those clients were lower than the management fee for the Fund and considered that, under the investment advisory agreement with the Fund, PIM performs additional services for the Fund that it does not provide to those other clients or services that are broader in scope, including oversight of the Fund's other service providers and activities related to compliance and the extensive regulatory and tax regimes to which the Fund is subject. The Trustees also considered the different entrepreneurial risks associated with PIM's management of the Fund and Pioneer's management of the other client accounts. The Trustees concluded that the management fee payable by the Fund to PIM was reasonable in relation to the nature and quality of the services provided by PIM to the Fund. Pioneer Equity Income Fund | Annual Report | 10/31/15 47 Profitability The Trustees considered information provided by PIM regarding the profitability of PIM with respect to the advisory services provided by PIM to the Fund, including the methodology used by PIM in allocating certain of its costs to the management of the Fund. The Trustees also considered PIM's profit margin in connection with the overall operation of the Fund. They further reviewed the financial results realized by PIM and its affiliates from non-fund businesses. The Trustees considered PIM's profit margins with respect to the Fund in comparison to the limited industry data available and noted that the profitability of any adviser was affected by numerous factors, including its organizational structure and method for allocating expenses. The Trustees concluded that PIM's profitability with respect to the management of the Fund was not unreasonable. Economies of Scale The Trustees considered PIM's views relating to economies of scale in connection with the Pioneer Funds as fund assets grow and the extent to which any such economies of scale are shared with funds and fund shareholders. The Trustees noted the breakpoint in the management fee schedule. The Trustees recognize that economies of scale are difficult to 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 Fund. The Trustees noted that profitability also may be an indicator of the availability of any economies of scale, although profitability may vary for other reasons including reductions in expenses. The Trustees concluded that economies of scale, if any, were being appropriately shared with the Funds. 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. Pioneer is the principal U.S. asset management business of Pioneer Global Asset Management, the worldwide asset management business of UniCredit Group, which manages over $150 billion in assets (including the Funds). Pioneer and the Funds receive reciprocal intangible benefits from the relationship, including mutual brand recognition and, for the Funds, direct and indirect access to the resources of a large global asset manager. The Trustees concluded that any such benefits received by Pioneer as a result of its 48 Pioneer Equity Income Fund | Annual Report | 10/31/15 relationship with the Funds were reasonable and their consideration of the advisory agreement between the Fund and PIM and the fees thereunder were unaffected by Pioneer's possible receipt of any such intangible benefits. 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.
