This is a welcome relief, and we are generally optimistic about the prospects for the economy going forward. Still, challenges remain. Unemployment is high. Consumer demand and loan growth are weak. And housing has not yet returned to normal. At Pioneer, we have long advocated the benefits of investing for the long term. This strategy has generally performed well for many investors. Those who remained invested in the market during the downturn have most likely seen their portfolios start to recover this year as the Dow Jones Industrial Average climbed back towards the 10,000 level. Many bond investors have similarly seen a strong rebound, with a broad-based recovery across many different fixed-income asset classes. The riskiest asset classes, such as high-yield bonds, have outperformed other fixed-income asset classes for most of 2009. At Pioneer, we are not changing the approach to investing that we have used for more than 80 years. We remain focused on company fundamentals and risk management. Our investment process is based on careful research into individual companies, quantitative analysis, and active portfolio management. This three-pillared process, which we apply to each of our portfolios, is supported by an integrated team approach and is designed to carefully balance risk and reward. While we see potential opportunities for making money in many corners of the markets around the globe, it takes research and experience to separate solid investment opportunities from speculation. Following this difficult period, many investors are rethinking their approach to investing and risk management. Some are questioning whether the basic investment principles they were taught in the past are still useful in today's markets. Complicating matters is that financial markets remain unpredictable. Our advice, as always, is to work closely with a trusted financial advisor to discuss your goals and work together to develop an investment strategy that meets your individual needs. There is no single best strategy that works for every investor. 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 2 Pioneer Floating Rate Fund | Annual Report | 10/31/09 www.pioneerinvestments.com. We greatly appreciate you putting your trust in us and we thank you for investing with Pioneer. Sincerely, /s/ Daniel K. Kingsbury Daniel K.

Pioneer Floating Rate Fund | Annual Report | 10/31/09 3 Portfolio Management Discussion | 10/31/09 Investments in floating-rate bank loans generated strong, positive results over the 12 months ended October 31, 2009, despite struggling in late 2008 amid fears about a credit crisis that had threatened the survival of major financial institutions. In the following interview, Jonathan Sharkey discusses the performance of Pioneer Floating Rate Fund during the 12-month period. Mr. Sharkey, a member of Pioneer's Fixed Income Department, is responsible for the daily management of the Fund. Q What were the principal factors affecting the Fund's performance over the 12 months ended October 31, 2009? A While the Fund generated a healthy return over the 12 months ended October 31, 2009, its emphasis on relatively high-quality loans tended to detract from benchmark-relative results during a period dominated by investors' renewed appetite for credit risk. Floating-rate bank loans suffered steep price losses in the early stages of the Fund's fiscal year (from November 1, 2008) -- especially the final two months of 2008 -- as the credit market was undermined by shrinking liquidity, the bankruptcy of investment bank Lehman Brothers and the financial problems of other major financial institutions. Aggravating the situation, a number of hedge funds started selling their investments in bank loans in order to reduce their own debts, or leverage. Market conditions improved somewhat in early 2009 when some better-quality loans, including BB-rated debt, started to recover. That was a good environment for Pioneer Floating Rate Fund, which had a quality focus and an average credit rating of BB. However, the Fund's relative advantage because of its higher-quality focus diminished as 2009 continued and investors became more willing to invest in lower-quality loans that carried greater credit risks. Key drivers of returns of the lower-rated names were: 1) bond funds seeking higher yields and investing in lower-rated loans that had deep discounts; 2) a strong high-yield bonds "new issue" market that led to the refinancing of bank loans, with prepayments redeployed in the secondary market; and 3) more stable economic reports suggesting better footing for some of the more stressed companies. While the Fund participated in the market's gains, its focus on better-quality loans and on first-lien loan obligations detracted from performance relative to the Barclays Index, as BB-rated loans underperformed B-rated and CCC-rated obligations by healthy margins. As the 12-month period progressed, we increased the Fund's overall diversification by adding to the number of portfolio holdings, and we invested the 4 Pioneer Floating Rate Fund | Annual Report | 10/31/09 Fund in loans of more companies positioned to benefit from an improving economy. We retained a significant Fund position in loans to the health care sector, while adding to positions in the information technology and broadcasting industries, and also reducing the Fund's relative position in the utilities industry. The largest portfolio concentration was in loans to consumer companies, which represented 27.7% of the Fund's investments at the end of the fiscal year on October 31, 2009. This segment is broad in definition and includes, in order of the Fund's weightings from highest to lowest: food suppliers, service companies, consumer staples, specialty retailers, gaming, building products, and auto parts suppliers. Reflecting the Fund's quality bias, on October 31, 2009, 68.6% of Fund assets were invested in loans rated BB or higher, while just 4.2% of assets were invested in lower-quality obligations rated CCC or lower. At the end of the Fund's fiscal year, the average credit rating of the portfolio's investments was BB-. At October 31, 2009, the Fund's default rate remained significantly lower than the Barclays Index. Q What were some of the investments that most influenced the Fund's results over the 12 months ended October 31, 2009? A Several of the Fund's bank loans performed particularly well. Among the Fund's top-performing positions were loans to Custom Building Products, which produces tile-related building materials and tools; Central Garden, which distributes garden and pet care supplies; and LodgeNet Interactive, which supplies electronic movie rental services to hotels and motels. Loans that detracted from the Fund's results included obligations of Fontainebleau, a casino in Las Vegas which defaulted during the period as banks refused to fund the company's revolving credit line; Hudson Products, which produces high-powered industrial fans for electric generating stations and refineries; Scitor, which provides technology services to the corporate market; and Niagara Steel, a specialty steel company for the auto and durable good sectors. Q What is your investment outlook? A Floating-rate loans, as an asset class, have a distinct advantage over most other yield-oriented investments in that they have the potential to increase their income to investors as interest rates increase. Another key benefit to bank loans is that they are secured with the assets and stock of the borrowing firm, and generally have stronger recovery ratings than bonds. Despite the rally to date, bank loans generally still were trading at discounts to their par values. In a rising interest-rate environment, demand for bank loans should increase, which would help support loan prices. The price appreciation potential would only be enhanced if interest rates start rising, although we are not ready to predict when that may occur. Given stabilization in the Pioneer Floating Rate Fund | Annual Report | 10/31/09 5 economy, the major ratings agencies are forecasting a drop in defaults over the next 12 months. A more stable economy should also enhance borrowers' ability to refinance or make acquisitions, which could also lead to more discounted loans getting taken out at par value. Going forward, we will continue to look for opportunities in bank loans that may have been previously out of favor with the market, but we do not intend to increase the Fund's overall risk profile. We believe bank loans present an interesting opportunity for appropriate investors who may be interested in the potential for generous income and some possible capital appreciation. Please refer to the Schedule of Investments on pages 15-31 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 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, 6 Pioneer Floating Rate Fund | Annual Report | 10/31/09 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, 2009 through October 31, 2009. Share Class A C Y Beginning Account Value $ 1,000.00 $ 1,000.00 $ 1,000.00 on 5/1/09 - -------------------------------------------------------------------------------- Ending Account Value $ 1,162.90 $ 1,157.87 $ 1,164.78 on 10/31/09 - -------------------------------------------------------------------------------- Expenses Paid During Period* $ 6.00 $ 10.88 $ 5.95 - -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.10%, 2.00% and 1.09%, for Class A, Class C and Class Y shares, respectively, multiplied by the average account value over the period, multiplied by 184/365 (to reflect the one-half year period). Pioneer Floating Rate Fund | Annual Report | 10/31/09 13 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.

Organization and Significant Accounting Policies Pioneer Floating Rate Fund (the Fund) is a series of Pioneer Series Trust VI, a Delaware statutory trust. The Fund is registered under the Investment Company Act of 1940 as a non-diversified, open-end management investment company. The investment objective of the Fund is to produce a high level of current income. The Fund offers 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 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. 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 contain unaudited information regarding the Fund's principal risks. Please refer to those documents when considering the Fund's principal risks. Pioneer Floating Rate Fund | Annual Report | 10/31/09 39 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 year. Actual results could differ from those estimates. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements, which are consistent with those policies generally accepted in the investment company industry: A.Security Valuation Security transactions are recorded as of trade date. The net asset value of the Fund is computed once daily, on each day the New York Stock Exchange (NYSE) is open, as of the close of regular trading on the NYSE. Senior floating rate loan interests (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. Senior loans for which no reliable price quotes are available will be valued by Loan Pricing Corporation through the use of pricing matrices to determine valuations. Fixed-income securities with remaining maturity of more than sixty days are valued at prices supplied by independent pricing services, which consider such factors as market prices, market events, quotations from one or more brokers, Treasury spreads, yields, maturities and ratings. Valuations may be supplemented by values obtained from dealers and other sources, as required. Equity securities that have traded on an exchange are valued at the last sale price on the principal exchange where they are traded. Equity securities that have not traded on the date of valuation, or securities for which sale prices are not available, generally are valued using the mean between the last bid and asked prices. Securities or loans 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 using fair value methods pursuant to procedures adopted by the Board of Trustees. Trading in foreign securities is substantially completed each day at various times prior to the close of the NYSE. The values of such securities used in computing the net asset value of the Fund's shares are determined as of such times. The Fund may use fair value methods if it is determined that a significant event has occurred after the close of the exchange or market on which the security trades and prior to the determination of the Fund's net asset value. Thus, the valuation of the Fund's securities may differ from exchange prices. At October 31, 2009, there were no securities that were valued using fair 40 Pioneer Floating Rate Fund | Annual Report | 10/31/09 value methods (other than securities valued using prices supplied by independent pricing services). Short-term fixed income securities with remaining maturities of sixty days or less generally are valued at amortized cost. Principal amounts of mortgage-backed securities are adjusted for monthly paydowns. Premiums and discounts related to certain mortgage-backed securities are amortized or accreted in proportion to the monthly paydowns. All discounts and premiums on debt securities are accreted or amortized daily, respectively, on a yield-to-maturity basis into interest income with a corresponding increase or decrease in the cost basis of the security. Interest income is recorded on the accrual basis. Dividend income is recorded on the ex-dividend date except that certain dividends from foreign securities where the ex-dividend date may have passed are recorded as soon as the Fund becomes aware of the ex-dividend data in the exercise of reasonable diligence. 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 for the prior three fiscal years are subject to examination by tax authorities. The amounts and characterizations of distributions to shareowners for financial reporting purposes are determined in accordance with federal income tax rules. Therefore, the sources of the Fund's distributions may be shown in the accompanying financial statements as from or in excess of net investment income or as from net realized gain on investment transactions, or as from paid-in capital, depending on the type of book/tax differences that may exist. At October 31, 2009, the Fund has reclassified $51,852 to increase undistributed net investment income and $51,852 to increase accumulated net realized loss on investments to reflect permanent book/tax differences. The reclassification has no impact on the net asset value of the Fund and is designed to present the Fund's capital accounts on a tax basis. At October 31, 2009 the Fund had a net capital loss carryforward of $2,007,156 of which the following amounts will expire between 2015 and 2017 if not utilized: $132,347 in 2015, $907,531 in 2016 and $967,278 in 2017. Pioneer Floating Rate Fund | Annual Report | 10/31/09 41 The tax character of distributions paid during the years ended October 31, 2009 and October 31, 2008 was as follows: 2009 2008 Distributions paid from: Ordinary income $1,926,533 $1,945,233 - ----------------------------------------------------------- Total $1,926,533 $1,945,233 =========================================================== The following shows the components of distributable earnings on a federal income tax basis at October 31, 2009: 2009 Distributable earnings: Undistributed ordinary income $ 230,489 Dividends payable (154,251) Capital loss carryforward (2,007,156) Unrealized depreciation (770,129) - ----------------------------------------------------------- Total $ (2,701,047) =========================================================== The difference between book-basis and tax-basis unrealized depreciation is attributable to the tax deferral of losses on wash sales, 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 approximately $6,510 in underwriting commissions on the sale of Class A shares during the year ended October 31, 2009. D.Class Allocations Income, common expenses and realized and unrealized gains and losses are calculated at the Fund level and allocated daily to each class of shares based on its respective percentage of adjusted net assets at the beginning of the day. Distribution fees are calculated based on the average daily net asset value attributable to Class A 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). 42 Pioneer Floating Rate Fund | Annual Report | 10/31/09 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 and at the same time, except that net investment income dividends to Class A, Class C, and Class Y shares can reflect different transfer agent and distribution expense rates. E.Repurchase Agreements With respect to repurchase agreements entered into by the Fund, the value of the underlying securities (collateral), including accrued interest, is required to be equal to or in excess of the repurchase price. The collateral for all repurchase agreements is held in safekeeping in the customer-only account of the Fund's custodian or a subcustodian of the Fund. The Fund's investment adviser, Pioneer Investment Management, Inc. (PIM), is responsible for determining that the value of the collateral remains at least equal to the repurchase price. 2.Management Agreement PIM, a wholly owned indirect subsidiary of UniCredit, manages the Fund's portfolio. Management fees are calculated daily at the annual rate of 0.60% of the Fund's average daily net assets up to $500 million and 0.55% of the excess of $500 million. For the year ended October 31, 2009, the effective management fee (excluding waivers and/or assumption of expenses) was equivalent to 0.60% of the Fund's average daily net assets. PIM has contractually agreed to limit ordinary operating expenses to the extent required to reduce Fund expenses to 1.10% and 2.00% of the Fund's average daily net assets attributable 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, 2011 for Class C shares. There can be no assurance that PIM will extend the expense limitation agreement for any 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 $1,816 in management fees, administrative costs and certain other reimbursements payable to PIM at October 31, 2009. 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. Pioneer Floating Rate Fund | Annual Report | 10/31/09 43 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 October 31, 2009, such out of pocket expenses by class of shares were as follows: Shareholder Communications: Class A $5,760 Class C 2,550 Class Y 1,024 - -------------------------------------------- Total $9,334 ============================================ Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $5,501 in transfer agent fees and out-of-pocket reimbursements payable to PIMSS at October 31, 2009. 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 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 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. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $1,096 in distribution fees payable to PFD at October 31, 2009. 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 (within 12 months for purchases made on or after April 1, 2009). 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 purchases 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 October 31, 2009, no CDSCs were paid to PFD. 44 Pioneer Floating Rate Fund | Annual Report | 10/31/09 5.Expense Offset Arrangements The Fund has entered into certain expense offset arrangements with PIMSS resulting in a reduction in the Fund's total expenses due to interest earned on cash held by PIMSS. For the year ended October 31, 2009, the Fund's expenses were reduced by $6 under such arrangements. 6.Unfunded Loan Commitments As of October 31, 2009, the Fund had unfunded loan commitments of approximately $278,813 (excluding unrealized appreciation on those commitments of $477 as of October 31, 2009), which could be extended at the option of the borrower pursuant to the following loan agreements: Unfunded Borrower Commitment CHS/Community Health Systems, Inc., Delayed Draw Term Loan $ 2,427 Dollar Financial Corp., Delayed Draw Term Loan $ 21,187 Flextronics International, Ltd., A-1-A Delayed Draw Loan $ 8,928 Lear Corp., Delayed Draw Loan $200,000 Warner Chilcott Co. LLC, Delayed Draw Term Loan $ 46,271 7. Subsequent Events In preparing these financial statements, PIM has evaluated the impact of all events and transactions for potential recognition or disclosure through December 21, 2009 and has determined that there were no subsequent events requiring recognition or disclosure in the financial statements.

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, 2009, by correspondence with the custodian, brokers and agent banks or by other appropriate auditing procedures where replies from brokers and agent banks 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, 2009, 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, 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 21, 2009 46 Pioneer Floating Rate Fund | Annual Report | 10/31/09 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 93.91% and 0%, respectively.

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.
