Pioneer Research Fund | Annual Report | 12/31/12 1 President's Letter Dear Shareowner, Pioneer has been cautiously optimistic about the U.S. economy from the start of the year, and the data continues to be encouraging. Employment continues to rise, albeit slowly, and we believe it should continue to do so in 2013, barring a negative shock to the system. The housing and auto sectors continue to recover, benefiting from record-low interest rates. Banks' willingness to lend to consumers and businesses also continues to rise, broad measures of inflation remain subdued, and, if the weather improves in 2013, that should help to bring food prices back down. While corporate profit growth has slowed, many U.S. companies still have strong balance sheets and continue to display the ability to both pay and increase dividends*. While the so-called "fiscal cliff " scheduled to take effect at year-end dominated the media in December--and while no deal was struck before markets closed for the year--investors who owned financial assets like equities and high-yield corporate bonds generally enjoyed good returns in 2012. The Standard & Poor's 500 Index returned 16% in 2012, and the Bank of America Merrill Lynch High Yield Master II Index returned 15.6%. Meanwhile, the higher-quality Barclays Capital Aggregate Bond Index gained 4.2% for the year, the safer-still Barclays Capital Intermediate Treasuries Index returned 3.9%, and 3-month Treasury bills, generally regarded as essentially "risk free" by the markets, returned just 0.1% in 2012. Despite generally improving economic conditions and positive market returns in 2012, investors still face daunting challenges in the year ahead, although we remain optimistic that the underlying economic trends are moving in the right direction. The year-end "fiscal cliff " deal did not eliminate the risk of further tax increases or spending cuts, nor did it eliminate the risk that the U.S. could face further downgrades to its credit rating from one or more of the major ratings agencies.The Federal Reserve Board continues to provide extraordinary support to the U.S. economy and the bond market, but will not do so indefinitely. Europe has made progress towards dampening its sovereign-debt crisis, but has not resolved the problem as yet; the region also was mired in a recession as 2012 drew to a close. In Asia, Japan continues to struggle with low economic growth, * Dividends are not guaranteed. 2 Pioneer Research Fund | Annual Report | 12/31/12 deflation, high levels of debt, and an aging population. In the emerging markets, China and other developing economies, while generally in better shape than most "developed" markets, also face a range of ongoing challenges. While most of the risks outlined above are widely recognized and may already be "priced in" to the market, we believe investors should continue to expect market volatility tied to these factors. At Pioneer, we have long advocated the benefits of staying diversified and investing for the long term. And while diversification alone does not assure a profit or protect against loss in a declining market, we believe there are still opportunities for prudent investors to earn attractive returns. Our advice, as always, is to work closely with a trusted financial advisor to discuss your goals and work together to develop an investment strategy that meets your individual needs, keeping in mind that there is no single best strategy that works for every investor. In 2013, Pioneer proudly celebrates its 85th anniversary. Since 1928, our investment teams have sought out attractive opportunities in global equity and bond markets, using in-depth research to identify undervalued individual securities, and using thoughtful risk management to construct portfolios which balance potential risks and reward in an ever-changing world. We encourage you to learn more about Pioneer and our time-tested approach to investing by consulting with your financial advisor or visiting us online at us.pioneerinvestments.com. We greatly appreciate your trust in us, and we thank you for investing with Pioneer. Sincerely, /s/ Daniel K. Kingsbury Daniel K. Kingsbury President and CEO Pioneer Investment Management USA, Inc.

Pioneer Research Fund | Annual Report | 12/31/12 3 Portfolio Management Discussion | 12/31/12 Despite a host of concerns about the health of the U.S. economy, domestic equities delivered generally solid performance during the 12 months ended December 31, 2012. In the following interview, Paul Cloonan discusses the investment environment during the 12-month period and the factors that affected the performance of Pioneer Research Fund. Mr. Cloonan, senior vice president and co-head of equity research at Pioneer, is part of the investment team responsible for the day-to-day management of the Fund. Q How would you describe the investment environment for equities during the 12 months ended December 31, 2012? A While a number of worries hovered over the equity market and created intermittent periods of volatility, stocks, in general, produced solid returns during the 12-month period. Among the issues causing investors to worry during the period were evidence of slowing global economic growth trends, decelerating corporate earnings growth rates, and a stubbornly high U.S. jobless rate. Anxieties about the U.S. election in November and uncertainties about how political infighting in Washington could affect fiscal decisions also unsettled investors. Nevertheless, the stock market fared well over the 12-month period as equities continued to look attractive relative to other asset classes, including fixed-income securities, which were, by and large, offering very low yields. Near year-end, especially, investors increasingly looked forward and saw more reason for optimism than pessimism regarding stocks. The reasons for optimism included steady, if modest, economic growth trends, slight improvements in unemployment figures, and pro-growth monetary policies implemented by central banks located in major economies, including the United States, China and Europe. By industry in 2012, the strongest absolute returns in the equity market came from the diversified financials, media and retailing groups, while the weakest performance came from companies in the semiconductor, utilities, consumer services and energy categories. Q How did the Fund perform in that environment during the 12 months ended December 31, 2012? A Pioneer Research Fund's Class A shares returned 14.51% at net asset value during the 12 months ended December 31, 2012, while the Fund's benchmark, the Standard & Poor's 500 Index (the S&P 500), returned 15.99%. During the same period, the average return of the 944 mutual funds in Lipper's Large Cap Core Funds category was 14.95%. 4 Pioneer Research Fund | Annual Report | 12/31/12 Q What were the reasons behind the Fund's underperformance of the S&P 500 during the 12 months ended December 31, 2012, and which investments produced the most disappointing results? A The Fund's benchmark-relative results during the 12-month period were hurt the most by underperforming stock selections in the information technology and materials sectors--in particular, within information technology, the Fund's investments in software and technology hardware were its weakest performers during the period. In software, the major detractor from relative returns was the Fund's position in Rovi, which we eliminated from the portfolio in July after the company lowered its earnings forecasts for the second quarter, and for the overall year. The disappointing earnings announcement came after Rovi's prospects had been called into question when Cisco Systems acquired one of its competitors, and after Rovi had moved to increase the company's indebtedness. During the period, we also sold the Fund's position in another major disappointment from the information technology sector: Hewlett-Packard (HP). We had become increasingly worried about HP's ability to turn around its many businesses and also fretted about the prospects for HP's personal computer business, which was losing ground in an industry segment that is under constant attack from newer technologies, including tablets. Another underperforming investment that we eliminated from the portfolio during the 12-month period was Celanese, from the materials sector. Celanese, a major chemical company, was registering disappointing results from its acetate business, while taking an unexpectedly long time to develop a new technology for the production of ethanol. Stock selection in energy also detracted from the Fund's benchmark-relative returns during the period, with a position in Anadarko Petroleum, an energy exploration and production company, the weakest relative performer in the sector. We sold the portfolio's position after the stock performed poorly and as Anadarko faced uncertainty about the outcome of a major lawsuit filed against the company. Q What types of investments had the greatest positive influence on the Fund's performance relative to the S&P 500 during the 12 months ended December 31, 2012? A The Fund's investments in the consumer sectors performed quite well during the 12-month period, with holdings in the media, and food, beverage and tobacco industries contributing significantly to relative returns. In addition, while the Fund's holdings in the information technology sector underperformed the benchmark's sector holdings during the period, the portfolio did own some stocks in the semiconductor field that contributed to relative returns. Pioneer Research Fund | Annual Report | 12/31/12 5 The top individual contributor to benchmark-relative results during the period was the portfolio's position in Constellation Brands from the food, beverage and tobacco group. Constellation Brands, which owns a number of wine companies as well as interests in beer and beer distributors, performed especially well at the end of the year when the company announced that it planned to increase its stake in and acquire full control of Crown Imports, which distributes Corona and other popular beer brands in the U.S. Also in the food, beverage and tobacco group, the Fund's investment in Fomento Economico Mexicana (FEMSA) rose in value during the period on strong results from the company's Coca-Cola soft drink distribution operations in Mexico and Central America. In the media group, the portfolio's top performer was Comcast, while Disney and Time Warner also contributed to returns. All three companies were able to improve their earnings during the period, while demonstrating strong pricing power. Comcast has pricing power in its broadband data service, while Disney and Time Warner have pricing power for their entertainment content with advertisers and distributors. Among the Fund's semiconductor holdings, ASML's positive performance during the period was notable, as the company gained in value by advancing its technology and improving its competitive position. Three of ASML's major customers (Intel, Taiwan Semiconductor and Samsung Electronics) are now long-term shareholders in the company, and each has committed to contributing funding to ASML's research and development efforts over the next few years. We sold the Fund's position in ASML at the end of the year, after the stock had appreciated significantly. In addition to the healthy returns coming from the top three groups, the Fund's relative performance also received major support from portfolio investments in credit card company Discover Financial Services and in capital goods company Manitowoc, which produces goods for both the construction and food services industries. Q Could you discuss some of the changes you made to the Fund's portfolio during the 12 months ended December 31, 2012? A Two of the most prominent additions we made to the portfolio during 2012 were two major financial institutions: Citigroup and Goldman Sachs. We were attracted by the low stock valuation of Citigroup, a major global banking institution, at a time when regulatory issues that earlier had clouded the company's prospects were becoming resolved. Citigroup's prospects also appeared to be brightening as the global markets started stabilizing. In addition, the Fund acquired a stake in Goldman Sachs, another global company selling at an attractive share price. The large investment bank appeared to be in a stronger competitive position as expectations grew that some of Goldman Sachs' European competitors might scale back their operations. 6 Pioneer Research Fund | Annual Report | 12/31/12 In the retail industry, we added two prominent national hardware and home improvement product chains to the Fund during the period: Home Depot and Lowe's. We believe both companies to be well positioned to benefit from the recovery in the housing industry as well as from increased home renovation and repair activity. In the energy sector, we added oil services company Schlumberger and exploration-and-production company Marathon Oil to the Fund during the period. We viewed Schlumberger as a key beneficiary of the strengthening market for oil services operations, while Marathon was selling at a cheap valuation and appeared poised to improve its operating performance. While we added Schlumberger and Marathon during the period, we sold the Fund's stake in diversified energy company ExxonMobil. While the company had performed well when the Fund owned it, we thought there were better opportunities available in other energy-related companies. We also eliminated the Fund's positions in diversified financials company JPMorgan Chase after major problems emerged in the company's London trading operations; and in pharmaceutical company Merck, because we saw fewer opportunities in the company's pipeline of new drug products. Q What is your investment outlook? A Our investment methodology for the Fund is built upon bottom-up analysis and stock selection, rather than analysis of macroeconomic trends and patterns. Nevertheless, we think the equity market overall remains attractive relative to other asset classes. Stocks valuations have remained appealing, and we think it makes sense that more investor capital should start moving into equities this year, following an extended period (several years) during which more investor assets have been flowing into fixed-income investments. Our approach to stock-picking emphasizes fundamental analysis. We believe the approach is durable and repeatable and can deliver reasonable investment results for the Fund at different periods within the business cycle, and under a variety of market conditions. Note to shareholders: Pioneer's Board of Trustees has approved the reorganization of Pioneer Research Fund into Pioneer Value Fund. It is expected that the reorganization will be completed in April or May 2013. The combined fund will have the same investment strategies and policies as, and be managed by the management team of, Pioneer Research Fund (led by Paul Cloonan, Pioneer's co-head of equity research, U.S.). It is anticipated that the performance history of the combined fund will be that of Pioneer Research Fund. The combined fund will be named Pioneer Core Equity Fund. Subject to shareholder approval, Pioneer Value Fund also will adopt a new management fee, and the current investment objective of Pioneer Research Fund, which is long-term capital growth. These changes would be effective at the time of the reorganization.

All results are historical and assume the reinvestment of dividends and capital gains. Other share classes are available for which performance and expenses will differ. Performance results reflect any applicable expense waivers in effect during the periods shown. Without such waivers Fund performance would be lower. Waivers may not be in effect for all funds. Certain fee waivers are contractual through a specified period. Otherwise, fee waivers can be rescinded at any time. See the prospectus and financial statements for more information. The performance table and graph do not reflect the deduction of fees and taxes that a shareowner would pay on Fund distributions or the redemption of Fund shares. 14 Pioneer Research Fund | Annual Report | 12/31/12 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 Research Fund Based on actual returns from July 1, 2012, through December 31, 2012.
-------------------------------------------------------------------------------- Share Class A B C Y -------------------------------------------------------------------------------- Beginning Account Value $1,000.00 $1,000.00 $1,000.00 $1,000.00 on 7/1/12 -------------------------------------------------------------------------------- Ending Account Value $1,049.78 $1,045.35 $1,044.31 $1,051.28 (after expenses) on 12/31/12 -------------------------------------------------------------------------------- Expenses Paid $6.44 $11.05 $11.05 $5.26 During Period* --------------------------------------------------------------------------------
* Expenses are equal to the Fund's annualized expense ratio of 1.25%, 2.15%, 2.15%, and 1.02% for Class A, Class B, Class C, and Class Y shares, respectively, multiplied by the average account value over the period, multiplied by 184/366 (to reflect the one-half year period). Pioneer Research Fund | Annual Report | 12/31/12 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 Research Fund Based on a hypothetical 5% per year return before expenses, reflecting the period from July 1, 2012, through December 31, 2012.

Purchases and sales of securities (excluding temporary cash investments) for the year ended December 31, 2012 aggregated $39,168,815 and $33,871,794, respectively. Various inputs are used in determining the value of the Fund's investments. These inputs are summarized in the three broad levels listed below. Level 1 - quoted prices in active markets for identical securities. Level 2 - other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.) See Notes to Financial Statements -- Note 1A. Level 3 - significant unobservable inputs (including the Fund's own assumptions in determining fair value of investments) See Notes to Financial Statements -- Note 1A. Generally, equity securities are categorized as Level 1, fixed income securities and senior loans as Level 2 and securities valued using fair value methods (other than prices supplied by independent pricing services) as Level 3. See Notes to Financial Statements -- Note 1A. The following is a summary of the inputs used as of December 31, 2012, in valuing the Fund's investments:

The accompanying notes are an integral part of these financial statements. Pioneer Research Fund | Annual Report | 12/31/12 31 Notes to Financial Statements | 12/31/12 1. Organization and Significant Accounting Policies Pioneer Research Fund (the Fund) is a Delaware statutory trust registered under the Investment Company Act of 1940 as a diversified, open-end management investment company. The investment objective of the Fund is to seek long-term capital growth. The Fund offers four classes of shares designated as Class A, Class B, Class C and Class Y shares. 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 shares. Class B shares convert to Class A shares approximately eight years after the date of purchase. The Fund's financial statements have been prepared in conformity with U.S. generally accepted accounting principles that require the management of the Fund to, among other things, make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income, expenses and gain or loss 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: 32 Pioneer Research Fund | Annual Report | 12/31/12 A. Security Valuation Security transactions are recorded as of trade date. The net asset value of the Fund is computed once daily, on each day the New York Stock Exchange (NYSE) is open, as of the close of regular trading on the NYSE. In computing the net asset value, securities that have traded on an exchange are valued at the last sale price on the principal exchange where they are traded. Securities that have not traded on the date of valuation, or securities for which sale prices are not available, generally are valued at the mean between the last bid and asked prices. Short-term fixed-income securities with remaining maturities of sixty days or less generally are valued at amortized cost. Shares of money market mutual funds are valued at their net asset value. Trading in foreign securities is substantially completed each day at various times prior to the close of the NYSE. The values of such securities used in computing the net asset value of the Fund's shares are determined as of such times. Securities for which independent pricing services are unable to supply prices or for which market prices and/or quotations are not readily available or are considered to be unreliable are valued by or at the direction or with the approval of the Valuation Committee using fair value methods pursuant to procedures adopted by the Board of Trustees. The Valuation Committee is comprised of certain members of the Board of Trustees. The Fund may use fair value methods if it is determined that a significant event has occurred after the close of the exchange or market on which the security trades and prior to the determination of the Fund's net asset value. Examples of a significant event might include political or economic news, corporate restructurings, natural disasters, terrorist activity or trading halts. Thus, the valuation of the Fund's securities may differ significantly from exchange prices and such differences could be material. Pioneer Investment Management, Inc. (PIM) is responsible for monitoring developments that may impact fair valued securities and for discussing and assessing fair values on an ongoing basis, and at least quarterly, with the Valuation Committee. At December 31, 2012, there were no securities that were valued using fair value methods (other than securities that were valued using prices supplied by independent pricing services). Inputs used when applying fair value methods to value a security may include credit ratings, the financial condition of the company, current market conditions and comparable securities. Dividend income is recorded on the ex-dividend date, except that certain dividends from foreign securities where the ex-dividend date may have passed are recorded as soon as the Fund becomes aware of the ex-dividend Pioneer Research Fund | Annual Report | 12/31/12 33 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. B. Foreign Currency Translation The books and records of the Fund are maintained in U.S. dollars. Amounts denominated in foreign currencies are translated into U.S. dollars using current exchange rates. Net realized gains and losses on foreign currency transactions, if any, represent, among other things, the net realized gains and losses on foreign currency contracts, disposition of foreign currencies and the difference between the amount of income accrued and the U.S. dollars actually received. Further, the effects of changes in foreign currency exchange rates on investments are not segregated in the statement of operations from the effects of changes in market price of those securities, but are included with the net realized and unrealized gain or loss on investments. C. Forward Foreign Currency Contracts The Fund may enter into forward foreign currency contracts (contracts) for the purchase or sale of a specific foreign currency at a fixed price on a future date. All contracts are marked to market daily at the applicable exchange rates, and any resulting unrealized gains or losses are recorded in the Fund's financial statements. The Fund records realized gains and losses at the time a portfolio hedge is offset by entry into a closing transaction or extinguished by delivery of the currency. Risks may arise upon entering into these contracts from the potential inability of counterparties to meet the terms of the contract and from unanticipated movements in the value of foreign currencies relative to the U.S. dollar. The Fund had no outstanding portfolio or settlement hedges as of December 31, 2012. D. Federal Income Taxes It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income and net realized capital gains, if any, to its shareowners. Therefore, no provision for federal income taxes is required. As of December 31, 2012, the Fund did not have any interest and penalties related to uncertain tax positions, which, if applicable, would be recorded as an income tax expense in the Statement of Operations. Tax years for the prior three fiscal years are subject to examination by Federal and State tax authorities. 34 Pioneer Research Fund | Annual Report | 12/31/12 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 December 31, 2012, the Fund reclassified $10,572 to decrease paid-in capital, $4,171 to increase undistributed net investment income, and $6,401 to decrease accumulated net realized loss on investments to reflect permanent book/tax differences. These adjustments have no impact on net assets or the results of operations. At December 31, 2012, the Fund had a net capital loss carryforward of $27,261,881 of which the following amounts will expire in 2016 and 2017 if not utilized: $990,872 in 2016 and $26,271,009 in 2017. The tax character of distributions paid during the years ended December 31, 2012 and December 31, 2011 was as follows:
--------------------------------------------------------------------------- 2012 2011 --------------------------------------------------------------------------- Distributions paid from: Ordinary income $466,344 $378,521 --------------------------------------------------------------------------- Total $466,344 $378,521 ===========================================================================
The following shows components of distributable earnings on a federal income tax basis at December 31, 2012:
--------------------------------------------------------------------------- 2012 --------------------------------------------------------------------------- Distributable earnings: Capital loss carryforward $(27,261,881) Net unrealized gain 10,854,434 --------------------------------------------------------------------------- Total $(16,407,447) ===========================================================================
The difference between book-basis and tax-basis net unrealized gain is attributable to the tax deferral of losses on wash sales, tax basis adjustments on Real Estate Investment Trust (REIT) holdings, partnerships and other holdings. Pioneer Research Fund | Annual Report | 12/31/12 35 E. 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 $3,807 in underwriting commissions on the sale of Class A shares during the year ended December 31, 2012. F. 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. During the year ended December 31, 2012, the Fund recognized gains of $816 in the settlement of class action lawsuits from several different companies, as reflected on the Statement of Operations. Distribution fees are calculated based on the average daily net asset value attributable to Class A, Class B and Class C shares of the Fund, respectively (see Note 4). Class Y shares do not pay distribution fees. All expenses and fees paid to the transfer agent, Pioneer Investment Management Shareholder Services, Inc. (PIMSS), for its services are allocated among the classes of shares based on the number of accounts in each class and the ratable allocation of related out-of-pocket expenses (see Note 3). Distributions to shareowners are recorded as of the ex-dividend date. Distributions paid by the Fund with respect to each class of shares are calculated in the same manner and at the same time, except that net investment income dividends to Class A, Class B, Class C and Class Y shares can reflect different transfer agent and distribution expense rates. G. 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 and 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. H. Repurchase Agreements With respect to repurchase agreements entered into by the Fund, the value of the underlying securities (collateral), including accrued interest, is required to be equal to or in excess of the repurchase price. The collateral for all repurchase agreements is held in safekeeping in the customer-only account of the Fund's custodian or a subcustodian of the Fund. PIM is responsible for determining that the value of the collateral remains at least equal to the repurchase price. 36 Pioneer Research Fund | Annual Report | 12/31/12 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 0.65% of the Fund's average daily net assets up to $1 billion, 0.60% of the next $4 billion and 0.55% on assets over $5 billion. For the year ended December 31, 2012, the net management fee (excluding waivers and/or assumption of expenses) was equivalent to 0.65% of the Fund's average daily net assets. PIM has contractually agreed to limit ordinary operating expenses of the Fund to the extent required to reduce Fund expenses to 1.25%, 2.15% and 2.15% of the average daily net assets attributable to Class A, Class B and Class C shares, respectively. Class Y shares do not have an expense limitation. Fees waived and expenses reimbursed during the year ended December 31, 2012 are reflected on the Statement of Operations. These expense limitations are in effect through May 1, 2014. There can be no assurance that PIM will extend the expense limitation agreement for a class of shares 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 $5,824 in management fees, administrative costs and certain other reimbursements payable to PIM at December 31, 2012. Effective March 5, 2012 PIM has retained Brown Brothers Harriman & Co. to provide certain sub-administration and accounting services to the Fund. 3. Transfer Agent PIMSS, a wholly owned indirect subsidiary of UniCredit, provides substantially all transfer agent and shareowner services to the Fund at negotiated rates. In addition, the Fund reimburses PIMSS for out-of-pocket expenses incurred by PIMSS related to shareholder communications activities such as proxy and statement mailings, outgoing phone calls and omnibus relationship contracts. For the year ended December 31, 2012, such out-of-pocket expenses by class of shares were as follows:
-------------------------------------------------------------------------------- Shareholder Communications: -------------------------------------------------------------------------------- Class A $26,947 Class B 2,323 Class C 2,501 Class Y 6,777 -------------------------------------------------------------------------------- Total $38,548 ================================================================================
Pioneer Research Fund | Annual Report | 12/31/12 37 Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $8,824 in transfer agent fees and out-of-pocket reimbursements payable to PIMSS at December 31, 2012. 4. Distribution Plan 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 and Class C 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. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $1,170 in distribution fees payable to PFD at December 31, 2012. In addition, redemptions of each class of shares (except 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. Class B shares that are redeemed within five years of purchase are subject to a CDSC at declining rates beginning at 4.00%, based on the lower of cost or market value of shares being redeemed. Redemptions of Class C shares within one year of purchase are subject to a CDSC of 1.00%, based on the lower of cost or market value of shares being redeemed. Shares purchased as part of an exchange remain subject to any CDSC that applied to the original purchase of those shares. There is no CDSC for Class Y shares. Proceeds from the CDSCs are paid to PFD. For the year ended December 31, 2012, CDSCs in the amount of $1,157 were paid to PFD. 5. Expense Offset Arrangements The Fund has entered into certain expense offset arrangements with PIMSS which may result in a reduction in the Fund's total expenses due to interest earned on cash held by PIMSS. For the year ended December 31, 2012, the Fund's expenses were not reduced under such arrangements. 38 Pioneer Research Fund | Annual Report | 12/31/12 Report of Independent Registered Public Accounting Firm To the Board of Trustees and Shareowners of Pioneer Research Fund: -------------------------------------------------------------------------------- We have audited the accompanying statement of assets and liabilities of Pioneer Research Fund (the "Fund"), including the schedule of investments, as of December 31, 2012, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five 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. 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. We were not engaged to perform an audit of the Fund's 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 and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2012, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. 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 Research Fund at December 31, 2012, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles. /s/ Ernst & Young LLP Boston, Massachusetts February 25, 2013 Pioneer Research Fund | Annual Report | 12/31/12 39 Approval of Investment Advisory Agreement Pioneer Investment Management, Inc. (PIM) serves as the investment adviser to Pioneer Research Fund (the Fund) pursuant to an investment advisory agreement between PIM and the Fund. In order for PIM to remain the investment adviser of the Fund, the Trustees of the Fund must determine annually whether to renew the investment advisory agreement for the Fund. The contract review process began in March 2012 as the Trustees of the Fund agreed on, among other things, an overall approach and timeline for the process. In July 2012, the Trustees approved the format of the contract review materials and submitted their formal request to PIM to furnish information necessary to evaluate the terms of the investment advisory agreement. The contract review materials were provided to the Trustees in July 2012 and September 2012. After reviewing and discussing the materials, the Trustees submitted a request for additional information to PIM, and materials were provided in response to this request. Meetings of the Independent Trustees of the Fund were held in July, September, October, and November, 2012 to review and discuss the contract review materials. In addition, the Trustees took into account the information related to the Fund provided to the Trustees at each regularly scheduled meeting. At a meeting held on November 13, 2012, based on their evaluation of the information provided by PIM and third parties, the Trustees of the Fund, including the Independent Trustees voting separately, unanimously approved the renewal of the investment advisory agreement for another year. In considering the renewal of the investment advisory agreement, the Trustees considered various factors that they determined were relevant, including the factors described below. The Trustees did not identify any single factor as the controlling factor in determining to approve the renewal of the agreement. Nature, Extent and Quality of Services The Trustees considered the nature, extent and quality of the services that had been provided by PIM to the Fund, taking into account the investment objective and strategy of the Fund. The Trustees reviewed the terms of the investment advisory agreement. The Trustees also reviewed PIM's investment approach for the Fund, its research process and its process for trade execution. The Trustees considered the resources of PIM and the personnel of PIM who provide investment management services to the Fund. The Trustees considered the non-investment resources and personnel of PIM involved in PIM's services to the Fund, including PIM's compliance and legal resources and personnel. The Trustees also considered the substantial attention and high priority given by PIM's senior management to the Pioneer fund complex. In addition, the Trustees considered PIM's plans to increase resources in its investment management function and other enhancements to PIM's advisory capabilities. 40 Pioneer Research Fund | Annual Report | 12/31/12 The Trustees considered that PIM supervises and monitors the performance of the Fund's service providers and provides the Fund with personnel (including Fund officers) and other resources that are necessary for the Fund's business management and operations. The Trustees also considered that, as administrator, PIM is responsible for the administration of the Fund's business and other affairs. The Trustees considered the fees paid to PIM for the provision of administration services. Based on these considerations, the Trustees concluded that the nature, extent and quality of services that had been provided by PIM to the Fund were satisfactory and consistent with the terms of the investment advisory agreement. Performance of the Fund The Trustees considered the performance results of the Fund over various time periods. They reviewed information comparing the Fund's performance with the performance of its peer group of funds as classified by Morningstar, Inc. (Morningstar), an independent provider of investment company data, and with the performance of the Fund's benchmark index. The Trustees considered that the Fund's annualized total return was in the second quintile of its Morningstar category for the one and three year periods ended June 30, 2012, and in the first quintile of its Morningstar category for the five year period ended June 30, 2012. (In all quintile rankings referred to throughout this disclosure, first quintile is most favorable to the Fund's shareowners. Thus, highest relative performance would be first quintile and lowest relative expenses would also be first quintile.) The Trustees concluded that the investment performance of the Fund was satisfactory. Management Fee and Expenses The Trustees considered information showing the fees and expenses of the Fund in comparison to the management fees and expense ratios of its peer group of funds as classified by Morningstar and also to the expense ratios of a peer group of funds selected on the basis of criteria determined by the Independent Trustees for this purpose using data provided by Strategic Insight Mutual Trust Research and Consulting, LLC (Strategic Insight), an independent third party. The Trustees considered that the Fund's management fee for the twelve months ended June 30, 2012 was in the second quintile relative to the management fees paid by other funds in its Morningstar peer group for the comparable period. The Trustees also considered the breakpoints in the management fee schedule and the reduced fee rates above certain asset levels. The Trustees considered that the Fund's expense ratio for the twelve months ended June 30, 2012 was in the third quintile relative to its Strategic Insight peer group for the comparable period. Pioneer Research Fund | Annual Report | 12/31/12 41 The Trustees reviewed gross and net management fees charged by PIM to its institutional and other clients, including publicly offered European funds, 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 to its other clients and considered the differences in management fees and profit margins for PIM's Fund and non-Fund services. 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 also considered the different entrepreneurial risks associated with PIM's management of the Fund and the other client accounts. The Trustees concluded that the management fee payable by the Fund to PIM was reasonable in relation to the nature and quality of the services provided by PIM. Profitability The Trustees considered information provided by PIM regarding the profitability of PIM with respect to the advisory services provided by PIM to the Fund, including the methodology used by PIM in allocating certain of its costs to the management of the Fund. The Trustees also considered PIM's profit margin in connection with the overall operation of the Fund. They further reviewed the financial results realized by PIM and its affiliates from non-fund businesses. The Trustees considered PIM's profit margins with respect to the Fund in comparison to the limited industry data available and noted that the profitability of any adviser was affected by numerous factors, including its organizational structure and method for allocating expenses. The Trustees concluded that PIM's profitability with respect to the management of the Fund was not unreasonable. Economies of Scale The Trustees considered PIM's views relating to economies of scale in connection with the Pioneer Funds as fund assets grow and the extent to which any such economies of scale are shared with funds and fund shareholders. The Trustees noted the breakpoints in the management fee schedule. The Trustees recognize that economies of scale are difficult to 42 Pioneer Research Fund | Annual Report | 12/31/12 identify and quantify, rarely identifiable on a Fund-by-Fund basis, and that, among other factors that may be relevant, are the following: fee levels, expense subsidization, investment by PIM in research and analytical capabilities and PIM's commitment and resource allocation to the Funds. The Trustees noted that profitability also may be an indicator of the availability of any economies of scale, although profitability may vary for other reasons particularly, for example during the recent difficult periods for financial markets, as the level of services was maintained notwithstanding a significant decline in PIM's fee revenues from the Funds. Accordingly, the Trustees concluded that economies of scale, if any, were being appropriately shared with the Fund. Other Benefits The Trustees considered the other benefits to PIM from its relationship with the Fund. The Trustees considered the character and amount of fees paid by the Fund, other than under the investment advisory agreement, for services provided by PIM and its affiliates. The Trustees further considered the revenues and profitability of PIM's businesses other than the fund business. The Trustees also considered the benefits to the Fund and to PIM and its affiliates from the use of "soft" commission dollars generated by the Fund to pay for research and brokerage services. The Trustees considered the intangible benefits to PIM by virtue of its relationship with the Fund and the other Pioneer funds. The Trustees concluded that the receipt of these benefits was reasonable in the context of the overall relationship between PIM and the Fund. Conclusion After consideration of the factors described above as well as other factors, the Trustees, including all of the Independent Trustees, concluded that the investment advisory agreement between PIM and the Fund, including the fees payable thereunder, was fair and reasonable and voted to approve the proposed renewal of the investment advisory agreement for the Fund.
