Investors have witnessed volatility of a magnitude that many have never before seen. Distance often provides the best vantage point for perspective. Still, we believe that the benefits of basic investment principles that have stood the test of time -- even in the midst of market turmoil -- cannot be underestimated. First, invest for the long term. The founder of Pioneer Investments, Philip L. Carret, began his investment career during the 1920s. One lesson he learned is that while great prosperity affords an advantageous time for selling stocks, extreme economic slumps can create opportunities for purchase. Indeed, many of our portfolio managers, who follow the value-conscious investing approach of our founder, are looking at recent market conditions as an opportunity to buy companies whose shares we believe have been unjustifiably beaten down by indiscriminate selling, but that we have identified as having strong prospects over time. While investors may be facing a sustained market downturn, we continue to believe that patience, along with staying invested in the market, are important considerations for long-term investors. A second principle is to stay diversified across different types of investments. The global scope of the current market weakness poses challenges for this basic investment axiom. But the turbulence makes now a good time to reassess your portfolio and make sure that your investments continue to meet your needs. We believe you should work closely with your financial advisor to find the mix of stocks, bonds and money market assets that is best aligned to your particular risk tolerance and investment objective. As the investment markets sort through the continuing crisis in the financial industry, we are staying focused on the fundamentals and risk management. With more than 80 years of experience behind us, we have learned how to navigate turbulent markets. At Pioneer Investments, risk management has always been a critical part of our culture -- not just during periods of extraordinary volatility. Our investment process is based on fundamental research, quantitative analysis and active portfolio management. This three-pillared process, which we apply to each of our portfolios, is supported by an integrated team approach and is designed to carefully balance risk and reward. While we 2 Pioneer Floating Rate Fund | Annual Report | 10/31/08 see potential chances for making money in many corners of the market, it takes research and experience to separate solid investment opportunities from speculation. We invite you to learn more about Pioneer and our time-tested approach to investing by consulting with your financial advisor or visiting us online at www.pioneerinvestments.com. Thank you for investing with Pioneer. Respectfully, /s/ Daniel K. Kingsbury Daniel K. Kingsbury President and CEO Pioneer Investment Management USA Inc.

Pioneer Floating Rate Fund | Annual Report | 10/31/08 3 Portfolio Management Discussion | 10/31/08 Bank loan investments struggled under the impacts of the spreading credit crisis during the 12 months ended October 31, 2008. As investor demand for bank loans to corporations contracted, the prices for bank loans fell, especially in the final two months of the period. In the following interview, Portfolio Manager Jonathan Sharkey discusses the factors that affected the performance of Pioneer Floating Rate Fund during the 12 months ended October 31, 2008. Mr. Sharkey, a member of Pioneer's Fixed Income team, is responsible for the daily management of the Fund. Q How did the Fund perform during the 12 months ended October 31, 2008? A Pioneer Floating Rate Fund Class A shares returned -17.57% at net asset value during the 12 months ended October 31, 2008. By comparison, the Fund's older benchmark, the CSFB Leveraged Loan Index, returned -20.33%, while the Barclays Capital (formerly Lehman Brothers) High Yield Performing Index, which will be the Fund's new benchmark, returned -21.59% over the same period. During the same 12 months, the average return of the 75 mutual funds in Lipper's Loan Participation Category was -20.79%. On October 31, 2008, the 30-day SEC yield on the Fund's Class A shares was 5.87%. Q What were the principal factors affecting the Fund's performance during the 12-month period? A The 12 months were the worst period for bank loans since indices began tracking their performance. Loans were affected, as were other credit- sensitive investments, by the continuing fallout from the credit crisis that began in the subprime mortgage market back in the summer of 2007. Problems in the market only became more extreme in the final two months of the annual reporting period. In October 2008 alone, the Barclays Capital (formerly Lehman Brothers) High Yield Loans Performing Index returned -14.45%, as investors avoided any securities that entailed credit risk. The catalyst for the dramatic downturn in October was the bankruptcy filing by investment bank Lehman Brothers. The bankruptcy filing created ripple effects affecting many financial institutions, particularly hedge funds, which began selling their bank loans for liquidity purposes. Then, structured investment vehicles started to hit their minimum price targets, triggering additional selling by hedge funds and other investors. As a result of the dramatic price losses during the month of October, bank loans ended the fiscal year at their lowest prices in the recorded history of the market. Despite this, bank loans on a year-to-date basis through October 31 still had outperformed many other asset classes, such as high-yield bonds and stocks, 4 Pioneer Floating Rate Fund | Annual Report | 10/31/08 although they did trail U.S. Treasuries, which outperformed virtually all other asset classes in a global flight-to-quality. While the Fund's performance was clearly very disappointing, the Fund did outperform its benchmarks and competitive peer group, primarily because of the higher-quality orientation of its portfolio. The average credit quality of the portfolio at October 31 was BB-. Among the Fund's BB investments was a larger concentration of BB+ securities, while loans rated B+ dominated the Fund's B holdings. The Fund owned no securities rated CCC and had fewer non-rated investments than the index weightings. In particular, the Fund had fewer covenant-light loans, which are bank loans that put relatively few restrictions on borrowers and offer relatively thin protection for investors. Our investments tended to be in loans that offered greater covenant protection during a 12-month period when covenant-light loans underperformed. During the fiscal year ended October 31, 2008, when opportunities presented themselves, we sought to add greater diversity of holdings to the Fund, increasing the number of different holdings from 65 at the beginning of the fiscal year on November 1, 2007, to 116 at October 31, 2008. This greater diversity of holdings gave the Fund additional protection in the event of poor performance by any single bank loan. Q What types of investments had the greatest influence on Fund performance during the 12-month period? A In a disappointing period for bank loans, the Fund's investments in loans to companies in the health care and utilities sectors tended to hold up well, as these traditionally defensive areas outperformed in a weakening economy. Our emphasis on quality also helped to protect the Fund in the face of rising default rates in the industry. During the 12 months ended October 31, the market default rate for bank loan investments rose from 0.25% to 3.5%. The Fund had two defaults during the period, including a loan to Land Source, which was a land development joint venture between homebuilder Lennar and the California Public Employees' Retirement System (CALPERS). The joint venture was hit hard by the real estate slump in California and filed for bankruptcy protection. We have retained the position in the Fund because we think there is an opportunity to recover some of the value of the investment. The other default was on loans to Washington Mutual, the giant thrift institution that ran into major difficulties in the mortgage crisis and eventually was taken over by JP Morgan Chase. Among other investments that detracted from results was a loan to American Airlines, which was backed by leases of older aircraft that were particularly affected by the rise in fuel prices. We sold that holding from the portfolio. Also detracting from the Fund's results were investments in loans to Pioneer Floating Rate Fund | Annual Report | 10/31/08 5 gambling-related institutions that performed poorly when gambling revenues declined due to the slowing economy. Q What is your investment outlook? A Our overall view as we look ahead is one of caution, because of the many uncertainties in the market. On a fundamental basis, we believe bank loans are trading at extraordinarily cheap levels and offer the opportunity for some price appreciation when the market begins to stabilize and eventually recover. We believe that even if market default rates were to increase from their present levels, bank loans at present prices offer considerable potential value. The market still may face some short-term volatility. With loan prices at unprecedented lows, the overall loan market is trading at intrinsic value (this means that the entire loan market is being priced by investors at levels that reflect historical recovery rates in bankruptcy). With loan prices at historically deep discounts, any payments by borrowers should allow investors to reap capital appreciation, and the payment proceeds would then need to be reinvested by fund managers. We believe that should boost both demand and prices, given the limited supply of new loan issues in today's market. Please refer to the Schedule of Investments on pages 15-26 for a full listing of Fund securities. Investments in high yield or lower-rated securities are subject to greater-than-average risk. The Fund may invest in securities of issuers that are in default or that are in bankruptcy. When interest rates rise, the prices of fixed-income securities in the Fund will generally fall. Conversely, when interest rates fall, the prices of fixed-income securities in the Fund will generally rise. The floating rate feature of the Fund's Senior Floating Rate Loans means that these investments will not experience capital appreciation in a declining interest rate environment. Investments in the Fund are subject to possible loss due to the financial failure of issuers of underlying securities and their inability to meet their debt obligations. Prepayment risk is the chance that mortgage-backed bonds will be paid off early if falling interest rates prompt homeowners to refinance their mortgages. Forced to reinvest the unanticipated proceeds at lower interest rates, the Fund would experience a decline in income and lose the opportunity for additional price appreciation associated with falling interest rates. The value of collateral, if any, securing a floating rate loan can decline, and may be insufficient to meet the issuer's obligations or may be difficult to liquidate. In addition, the Fund's access to collateral may be limited by bankruptcy or other insolvency laws. Although Pioneer normally will seek to avoid receiving non-publicly available information about the issuer of a loan, this decision not to receive the information may place it at a disadvantage, relative to other loan investors, in assessing the loan. The Fund is not diversified, which means that it can invest a higher percentage of its assets in the securities of any one issuer than a diversified fund. Being 6 Pioneer Floating Rate Fund | Annual Report | 10/31/08 non-diversified may magnify the Fund's losses from adverse events affecting a particular issuer. Some of the floating rate loans and other investments in which the Fund may invest will be considered to be illiquid. Illiquid securities may be difficult to dispose of at a fair price at the times when the Fund believes it is desirable to do so, and their market price is generally more volatile than that of more liquid securities. Illiquid securities are also more difficult to value, and investment of the Fund's assets in illiquid securities may restrict the Fund's ability to take advantage of market opportunities. Investing in foreign and/or emerging securities involves risks relating to interest rates, currency exchange rates, economic and political conditions. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political or regulatory developments or other risks affecting those industries or sectors. Past performance is no guarantee of future results, and there is no guarantee that market forecasts discussed will be realized.

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 Floating Rate Fund Based on actual returns from May 1, 2008 through October 31, 2008. - -------------------------------------------------------------------------------- Share Class A C Y - -------------------------------------------------------------------------------- Beginning Account Value $1,000.00 $1,000.00 $1,000.00 on 5/1/08 - -------------------------------------------------------------------------------- Ending Account Value $ 864.04 $ 841.92 $ 846.19 on 10/31/08 - -------------------------------------------------------------------------------- Expenses Paid During Period* $ 5.10 $ 9.26 $ 5.01 - -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.10%, 2.00% and 1.08%, for Class A, 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 Floating Rate Fund | Annual Report | 10/31/08 13 Comparing Ongoing Fund Expenses (continued) 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.

Pioneer Floating Rate Fund | Annual Report | 10/31/08 33 Notes to Financial Statements | 10/31/08 1. Organization and Significant Accounting Policies Pioneer Floating Rate Fund (the Fund) is a Delaware statutory trust registered under the Investment Company Act of 1940 as a non-diversified series of Pioneer Series Trust VI, an open-end management investment company. The investment objective of the Fund is to produce a high level of current income. The Trustees have authorized the issuance of three classes of shares designated as Class A, Class C, and Class Y shares. Class A, Class C and Class Y shares were first publicly offered on February 14, 2007. Each class of shares represents an interest in the same portfolio of investments of the Fund and has equal rights to voting, redemptions, dividends and liquidation, except that each class of shares can bear different transfer agent and distribution fees and has exclusive voting rights with respect to the distribution plans that have been adopted by Class A and Class C shareowners, respectively. There is no distribution plan for 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. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. The Fund invests in below investment grade debt securities. Debt securities rated below investment grade are commonly referred to as "junk bonds" and are considered speculative. These securities involve greater risk of loss, are subject to greater price volatility, and are less liquid, especially during periods of economic uncertainty or change, than higher rated debt securities. The Fund's investments in foreign markets or countries with limited developing markets may also subject the Fund to a greater degree of risk than in a developed market. These risks include disruptive political or economic conditions and the possible imposition of adverse governmental laws or currency exchange restrictions. The Fund's prospectuses (unaudited) contain information regarding the Fund's principal risks. Please refer to those documents when considering the Fund's risks. 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: 34 Pioneer Floating Rate Fund | Annual Report | 10/31/08 A. Security Valuation Security transactions are recorded as of trade date. The net asset value 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. Senior loans are valued in accordance with guidelines established by the Board of Trustees at the mean between the last available bid and asked prices from one or more brokers or dealers as obtained from Loan Pricing Corporation. For the limited number of Senior Loans for which no reliable price quotes are available, such Senior Loans will be valued by Loan Pricing Corporation through the use of pricing matrices to determine valuations. Fixed-income securities are valued at prices supplied by independent pricing services, which consider such factors as Treasury spreads, yields, maturities and ratings. Valuations may be supplemented by values obtained from dealers and other sources, as required. Equity securities are valued at the last sale price on the principal exchange where they are traded. Securities or loans for which quotations are not readily available are valued at their fair values as determined by, or under the direction of, the Board of Trustees and may include yield equivalents or a pricing matrix. Trading in foreign securities is substantially completed each day at various times prior to the close of the NYSE. The values of such securities used in computing the net asset value of the Fund's shares are determined as of such times. The Fund may also use the fair value of a security, including a non-U.S. security, when the closing market price on the primary exchange where the security is traded no longer accurately reflects the value of the security as of the close of the exchange. At October 31, 2008, one security has been fair valued, which represents 0.7% of net assets. Temporary cash investments are valued at cost, which approximates market value. Discount and premium on debt securities are accreted or amortized, respectively, daily into interest income on a yield-to-maturity basis with a corresponding increase or decrease in the cost basis of the security. Interest income is recorded on the accrual basis. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. B. Federal Income Taxes It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income and net realized capital gains, if any, to its shareowners. Therefore, no federal income tax provision is required. Tax years prior to 2004 are closed (not subject to examination by tax authorities) due to the expiration of statute of limitations; all other tax years are open. Pioneer Floating Rate Fund | Annual Report | 10/31/08 35 The amounts and characterizations of distributions to shareowners for financial reporting purposes are determined in accordance with federal income tax rules. Therefore, the sources of the Fund's distributions may be shown in the accompanying financial statements as from or in excess of net investment income or as from net realized gain on investment transactions, or as from paid-in capital, depending on the type of book/tax differences that may exist. At October 31, 2008 the Fund had a net capital loss carryforward of $1,039,878 of which the following amounts will expire between 2015 and 2016 if not utilized; $132,347 in 2015 and $907,531 in 2016. At October 31, 2008, the Fund has reclassified $25,803 to increase undistributed net investment income and $25,803 to increase accumulated net realized loss on investments, to reflect permanent book/tax differences. The reclassification has no impact on the net assets of the Fund and presents the Fund's capital accounts on a tax basis The tax character of distributions paid during the year ended October 31, 2008 and the period ended October 31, 2007 was as follows: - -------------------------------------------------------- 2008 2007 - -------------------------------------------------------- Distributions paid from: Ordinary Income $1,945,233 $1,221,099 - -------------------------------------------------------- Total $1,945,233 $1,221,099 - -------------------------------------------------------- The following shows the components of distributable earnings on a federal income tax basis at October 31, 2008: - -------------------------------------------------- 2008 - -------------------------------------------------- Distributable earnings: Undistributed ordinary income $ 61,716 Dividends payable (6,188) Capital loss carryforward (1,039,878) Unrealized depreciation (8,066,776) - -------------------------------------------------- Total (9,051,126) - -------------------------------------------------- The difference between book basis and tax basis unrealized depreciation is attributable to the tax treatment of premium, interest on defaulted bonds, and adjustments relating to catastrophe bonds. C. Fund Shares The Fund records sales and repurchases of its shares as of trade date. Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the Fund and a wholly owned indirect subsidiary of UniCredit S.p.A (UniCredit), earned $168 in underwriting commissions on the sale of Class A shares during the year ended October 31, 2008. 36 Pioneer Floating Rate Fund | Annual Report | 10/31/08 D. Class Allocations Income, common expenses and realized and unrealized gains and losses are calculated at the Fund level and allocated daily to all classes of shares based on their 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 and Class C shares of the Fund, respectively (See Note 4). Class Y shares are not subject to a distribution plan. Shareowners of each class participate in all expenses and fees paid to the transfer agent, Pioneer Investment Management Shareholder Services, Inc. (PIMSS), for its services, which are allocated based on the number of accounts in each class and the ratable allocation of related out-of-pocket expenses (see Note 3). The Fund declares as daily dividends substantially all of its net investment income. All dividends are paid on a monthly basis. Short-term capital gain distributions, if any, may be declared with the daily dividends. 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, at the same time, and in the same amount, except that Class A, Class C, and Class Y shares can bear different transfer agent and distribution expense rates. E. Repurchase Agreements With respect to repurchase agreements entered into by the Fund, the value of the underlying securities (collateral), including accrued interest received from counterparties, is required to be at least equal to or in excess of the value of the repurchase agreement at the time of purchase. The collateral for all repurchase agreements is held in safekeeping in the customer-only account of the Fund's custodian, or sub custodians. The Fund's investment adviser, Pioneer Investment Management, Inc. (PIM), is responsible for determining that the value of the collateral remains at least equal to the repurchase price. 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% on the first $500 million of the Fund's average daily net assets and 0.55% on average daily net assets over $500 million. For the year ended October 31, 2008, the effective management fee (net of waivers and/or assumption of expenses) was equivalent to 0.41% of the Fund's average daily net assets. PIM has agreed not to impose all or portion of its management fee and to assume other operating expenses of the Fund to the extent necessary to limit expenses to 1.10% and 2.00% of the Fund's average daily net assets attributable Pioneer Floating Rate Fund | Annual Report | 10/31/08 37 to Class A shares and Class C shares, respectively. These expense limitations are in effect through March 1, 2012 for Class A shares and through March 1, 2010 for Class C shares. 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. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $489 management fees, administrative costs and certain other services payable to PIM at October 31, 2008. 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. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $849 in transfer agent fees payable to PIMSS at October 31, 2008. 4. Distribution Plan The Fund adopted a Plan of Distribution with respect to Class A and Class C shares in accordance with Rule 12b-1 of the Investment Company Act of 1940. Pursuant to the Plan, the Fund pays PFD 0.25% of the Fund's 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 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. For the period from November 1, 2007 through January 31, 2008, PFD was reimbursed under the Plan of Distribution for distribution expenses in an amount up to 0.25% of the average daily net assets attributable to Class A shares. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $307 in distribution fees payable to PFD at October 31, 2008. 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 18 months of purchase. 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. Proceeds from the CDSCs are paid to PFD. For the year ended October 31, 2008, no CDSCs were paid to PFD. 38 Pioneer Floating Rate Fund | Annual Report | 10/31/08 5. Expense Offset and Agreements The Fund has entered into certain expense offset arrangements with PIMSS resulting in a reduction in the Fund's total expenses due to interest earned on cash held by PIMSS. For the year ended October 31, 2008, the Fund's expenses were reduced by $97 under such arrangements. 6. Unfunded Loan Commitments As of October 31, 2008, the Fund had unfunded loan commitments of approximately $321,429 (excluding unrealized depreciation on those commitments of $103,700 as of October 31, 2008), which could be extended at the option of the borrower pursuant to the following loan agreements: - --------------------------------------------------------------------------------- Unfunded Borrower Commitment - --------------------------------------------------------------------------------- Bausch & Lomb, Inc., Delayed Draw Term Loan $ 12,000 CHS/Community Health Systems, Inc., Delayed Draw Term Loan $ 23,202 Fontainebleau Las Vegas, LLC, Delayed Draw Term Loan $166,667 Interline Brands, Inc. -- Delayed Draw Term Loan $117,563 United Surgical Partners International, Inc., Delayed Draw Term Loan $ 1,997 7. New Pronouncements In September 2006, Statement of Financial Accounting Standards No. 157, Fair Value Measurements (SFAS 157), was issued and is effective for fiscal years beginning after November 15, 2007. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Management is currently evaluating the impact the adoption of SFAS 157 will have on the Fund's financial statement disclosures. In March 2008, Statement of Financial Accounting Standards No. 161, Disclosures about Derivative Instruments and Hedging Activities (SFAS 161), was issued and is effective for fiscal years beginning after November 15, 2008.

Management is currently evaluating the impact the adoption of SFAS 161 will have on the Fund's financial statement disclosures. Pioneer Floating Rate Fund | Annual Report | 10/31/08 39 Report of Independent Registered Public Accounting Firm To the Board of Trustees of Pioneer Series Trust VI and the Shareowners of Pioneer Floating Rate Fund - -------------------------------------------------------------------------------- We have audited the accompanying statement of assets and liabilities of Pioneer Floating Rate Fund (the "Fund") (one of the portfolios constituting Pioneer Series Trust VI), including the schedule of investments, as of October 31, 2008, 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 periods indicated therein. 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 October 31, 2008, by correspondence with the custodian, brokers and agent banks or by other appropriate auditing procedures where replies from brokers were not received. We believe that our audits provides 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 Floating Rate Fund at October 31, 2008, 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 periods indicated therein, in conformity with U.S. generally accepted accounting principles. /s/ Ernst & Young LLP Boston, Massachusetts December 19, 2008 40 Pioneer Floating Rate Fund | Annual Report | 10/31/08 ADDITIONAL INFORMATION (unaudited) The percentages of the Fund's ordinary income distributions that are exempt from nonresident alien (NRA) tax withholding resulting from qualified interest income and qualified short term gains were 79.50% and 4.24%, respectively.

(PIM) serves as the Fund's investment adviser pursuant to an investment advisory agreement between PIM and the Fund. The Trustees of the Fund, as required by law, determine whether to approve the investment advisory agreement for the Fund. In connection with their approval of the investment advisory agreement for the Fund, the Trustees received and reviewed a substantial amount of information provided by PIM in response to requests of the independent Trustees and their independent legal counsel. The independent Trustees met on a number of occasions with PIM and also separately with their independent legal counsel to evaluate and discuss the information provided to them by PIM. At a meeting held on November 14, 2006, based on their evaluation of the information provided by PIM, the Trustees, including the independent Trustees voting separately, unanimously approved the investment advisory agreement for the Fund. At a meeting held on January 8, 2008, the Trustees considered whether an amended and restated investment advisory agreement for the Fund should be approved for an initial period ending December 31, 2009. The management fee to be paid by the Fund to PIM under the amended and restated investment advisory agreement is the same as the management fee provided in the previously approved investment advisory agreement. Based on their evaluation of the information provided by PIM, including the information provided by PIM in connection with the Trustees' most recent approval of the previous investment advisory agreement, the Trustees, including the independent Trustees voting separately, unanimously approved the amended and restated investment advisory agreement. Shareholders of the Fund approved the amended and restated investment advisory agreement at a meeting held on May 13, 2008. In considering the amended and restated 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 amended and restated investment advisory agreement. Nature, Extent and Quality of Services The Trustees considered the nature, extent and quality of the services that were provided by PIM to the Fund under the previous investment advisory agreement, and that would continue to be provided by PIM to the Fund under the amended and restated investment advisory agreement, taking into account the investment objective and strategy of the Fund and the information related to the Fund provided to the Trustees at each quarterly meeting. The Trustees Pioneer Floating Rate Fund | Annual Report | 10/31/08 43 reviewed the terms of the amended and restated investment advisory agreement. 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 considered PIM's compliance and legal resources and personnel. In addition, the Trustees considered the other services that PIM provided under the previous investment advisory agreement and that PIM would continue to provide to the Fund under the amended and restated investment advisory agreement and that, as administrator, PIM is responsible for the administration of the Fund's business and other affairs. It was noted that PIM supervises and monitors the performance of the Fund's service providers and provides the Fund with personnel (including officers) as are necessary for the Fund's operations. The Trustees considered the fees paid to PIM for the provision of such services. Based on these considerations, the Trustees concluded that the nature, extent and quality of services that PIM would continue to provide to the Fund under the amended and restated investment advisory agreement, were satisfactory and consistent with the terms of the amended and restated investment advisory agreement. Performance of the Fund In considering the amended and restated investment advisory agreement, the Trustees noted that the Fund had only recently commenced operations. The Trustees considered the performance results of the Fund provided at regular Board meetings, as well as the performance results provided at regular Board meetings for other Pioneer Funds with similar investment objectives and strategies to the Fund. The Trustees concluded that the investment performance of the Fund was satisfactory. Management Fee and Expenses The Trustees considered that the management fee to be paid by the Fund to PIM under the amended and restated investment advisory agreement would be the same as the management fee to be paid by the Fund under the previously approved investment advisory agreement. The Trustees considered information on the fees and expenses of the Fund in comparison to the management fees of its peer group of funds as classified by Morningstar and the expense ratios of a peer group of funds selected on the basis of criteria determined by the independent Trustees for this purpose using data provided by Strategic Insight Mutual Fund Research and Consulting, LLC (Strategic Insight), an independent third party. The Trustees considered that the Fund's asset weighted management fee would rank below the median management fees paid by other funds in its peer group Morningstar category. The Trustees also considered the Fund's expense ratio, 44 Pioneer Floating Rate Fund | Annual Report | 10/31/08 and considered the contractual expense limitation agreed to by PIM with respect to the Fund. The Trustees concluded that the management fee payable by the Fund to PIM was reasonable in relation to the nature and quality of services provided, taking into account the fees charged by other advisers for managing comparable funds with similar strategies. The Trustees also concluded that the Fund's expense ratio was reasonable, taking into account the quality of services provided by PIM and the contractual expense limitation agreed to by PIM with respect to the Fund. Profitability The Trustees did not consider PIM's profitability with respect to the management of the Fund in approving the investment advisory agreement because the Fund had only recently commenced operations and profitability information was not available. Economies of Scale The Trustees considered the potential economies of scale with respect to the management of the Fund. The Trustees concluded that, because of the breakpoints in the management fee schedule and the reduced fee rates above certain asset levels, any perceived or potential economies of scale would be shared between PIM and the Fund. Other Benefits The Trustees considered the other benefits to PIM from its relationship with the Fund. The Trustees considered that affiliates of PIM serve as the Fund's transfer agent and distributor. The Trustees considered the receipt by PIM and its affiliates of sales loads and payments under Rule 12b-1 plans in respect of the Fund and the other Pioneer funds. The Trustees further 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 terms of the amended and restated investment advisory agreement between PIM and the Fund, including the fees payable thereunder, were fair and reasonable and voted to approve the amended and restated 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.
