They were particularly useful guides in recent months, when an otherwise healthy long-term bull market was buffeted by problems in the mortgage and banking industries. Since mid-year 2007, issues tied to poor underwriting practices in the subprime sector of the mortgage industry and to problems with risk management by banks and hedge funds have resulted in increased market volatility and rising concern about risks to U.S. economic growth. U.S. economic growth had slowed over the past two years, but this has been due as much to the natural maturation of the cyclical expansion, as U.S. factories approached full utilization and the labor market approached full employment, as to rising commodity prices or short-term interest rates. The slowdown was, therefore, not entirely unwelcome, as it reduced the threat of higher inflation. More recently, however, there has been increasing concern that falling home prices, and/or disruptions in financial markets pose a larger threat to continuing economic growth, and we have seen two cuts in short-term interest rates from the Federal Reserve despite strong economic growth in the second and third quarters of this year. A weaker U.S. dollar has put upward pressure on some prices, but it has also significantly benefited exporters and companies competing in the global marketplace, stimulating U.S. economic growth. Economic growth in the rest of the world remains relatively positive. In Europe, solid GDP growth has driven unemployment lower and supported growing consumption, although concerns about the impact of the strong Euro are a persistent source of worry. Japanese economic growth continues, albeit at a muted rate, and the country's deflationary problems are gradually receding. Economic growth in emerging market countries remains faster than in the developed world, led by China, which continues its rise as a world economic power. Looking forward, the economic outlook continues to appear generally positive, although real estate prices, subprime mortgage defaults, and the possibility of a liquidity/credit crunch represent growing sources of risk. Central banks have responded to the stresses in the inter-bank and commercial paper markets by acting as "lenders of last resort" and, in the case of the Federal Reserve, by cutting rates. The U.S. Federal Reserve and the world's other central banks continue to pursue policies aimed at producing low and stable inflation, believed to be the best backdrop for steady economic growth and low average unemployment over the long term. Keeping inflation low is also an important support for stock and bond valuations, and so central bank 2 Letter policies have also been "investor friendly." We view the Fed's recent rate cuts as temporarily "buying insurance" against a credit crunch, which would threaten economic growth rather than as an abandonment of its commitment to keeping inflation low. Even against this "wall of worry" backdrop, the long-term performance of major asset classes has remained positive. In the 12 months ending October 31, 2007, equity investors were by and large rewarded as, despite several interim corrections, the Standard & Poor's 500 Index returned 15%, the Dow Jones Industrial Average returned 18%, and the NASDAQ Composite Index returned 21%. International developed and emerging markets equities performed even better, reflecting both a weakening dollar (which boosts returns for U.S. dollar-based investors) and strong local currency returns, with the MSCI EAFE Developed Market Index returning 25% and the MSCI Emerging Markets Index returning 68% over the 12-month period. The U.S. bond market, as measured by the Lehman Aggregate Bond Index, returned 5% in the 12 months ending October 31, 2007. The U.S. high-yield bond market, as measured by the Merrill Lynch High Yield Bond Master II Index, returned 7% for the same period, reflecting its higher coupon yield. Sudden swings in the markets are always to be expected. Just as staying diversified and invested are important investment principles, it is also important to pay attention to asset allocation. As always, we encourage you to 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.

Over the period, bank loans backed by the assets of borrowing companies delivered generally positive results, despite some heightened volatility in July and August. In the following discussion, Jonathan Sharkey discusses the management of the Pioneer Floating Rate Fund since its inception on February 14, 2007, through the end of the Fund's first fiscal year, on October 31, 2007. Mr. Sharkey, a member of Pioneer's Fixed Income Group, is responsible for the daily management of the Fund. Q: How did the Fund perform? A: Pioneer Floating Rate Fund's Class A shares had a total return of 1.21%, at net asset value, from the Fund's inception on February 14, 2007, through October 31, 2007. During the same period, the Lehman High Yield Loans Performing Index returned 2.00%, while the average return of the 62 funds in Lipper's Loan Participating Funds category was 1.03%. On October 31, 2007, the 30-day SEC yield of the Fund's Class A shares was 5.35%. Call 1-800-225-6292 or visit www.pioneerinvestments.com for the most recent month-end performance results. Current performance may be lower or higher than the performance data quoted. The performance data quoted represents past performance, which is no guarantee of future results. Investment return and principal value will fluctuate, and shares, when redeemed, may be worth more or less than their original cost. Q: What was the investment environment like during the period? A: It was an unusual and challenging period to be investing in floating rate bank loans. When we launched investment activities on February 14, 2007, the market was in the midst of a massive number of refinancings of bank loans. It was a seller's market for bank loans, with demand high from both traditional investors and non-traditional investors, such as hedge funds, even as a heavy volume of new loan issues entered the market. As a consequence, many companies that had recently borrowed from banks wanted to refinance and obtain better terms for their debt. Many loans that 4 Pioneer Floating Rate Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- had been issued in recent months were trading above par value, and so it was not unusual for companies to want to retire their outstanding debt and refinance. That posed risks for investors in the secondary market for previously issued loans, as they had to face the possibility that outstanding loans could be retired at par value, which would mean a loss of principal. Facing those challenges, we carried a larger-than-normal cash balance in the early days of the Fund, and we focused principally on the new-loan issue market, generally avoiding the secondary market. In the new issue market, however, many loans were so-called covenant-lite loans. "Covenant-lite" is a term that has emerged to describe loans that have fewer restrictions on the borrowing company than traditional bank loans. A typical covenant-lite loan, for example, might not require the borrowing company to adhere to the business plan it submitted in applying for the loan. For most of the period, we avoided covenant-lite loans and focused primarily on newly issued floating-rate loans with strong covenant protection. We also took advantage of Pioneer's expertise in high-yield bonds to invest in such bonds, focusing primarily on securities that offered the bondholder the added protection of a first lien on company assets. Volatility in the market for bank loans increased somewhat in May when a new index - the Loan Credit Default Swaps Index - was introduced, giving short-term investors a new derivative security to trade in place of bank loans. However, the environment changed more dramatically in July when problems in the subprime mortgage market resulted in heightened volatility even in the bank-loan market. Many hedge funds that had invested in bank loans moved to sell them when the funds faced pressure from their lenders because of other investments. Hedge funds first sold the bank loans because the loans were more liquid - or more easily traded - than other investments they had made. That created a technical imbalance in the supply and demand dynamics of the bank loan market, causing some reductions in the prices of loans as supply outstripped demand and prices for secondary loans started to fall - especially in the face of a large pipeline of new-loan issues coming to market. The market slump occurred despite strong underlying fundamentals in bank loans. Even though the default rates for floating-rate loans were very low by historical standards, the supply-and-demand imbalance depressed the market. 5 Pioneer Floating Rate Fund - -------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 10/31/07 (continued) - -------------------------------------------------------------------------------- The market then stabilized in late August and posted strong, positive results in September and October. Over the full period, we saw a transition from a seller's market, which favored borrowing companies, to a buyer's market, which favored investors such as mutual funds. Q: How was the Fund positioned, and how did that affect performance? A: We focused primarily on new-loan issues with strong covenant protection. At the end of the fiscal period, on October 31, 2007, more than 80% of Fund assets were invested in loans with solid protection. That emphasis was a major support to performance, especially when the market became more volatile mid-way through the period. While we did have a small position in covenant-lite loans - about 7% of Fund assets on October 31 - we were careful to make sure they were loans to high-quality companies with good prospects. By comparison, the index at the end of the period had 18% covenant-lite loans in it. At the start of the Fund's operations, year-to-date issuance of covenant-lite loans was nearly 30% of the new issue market. Moreover, the overwhelming majority of the covenant-light loans in which we were invested were judged by the Moody's and Standard & Poor's rating services as offering the highest recovery protection. The ratings indicated that loan holders were judged to have an excellent opportunity to recover their investments should the business fundamentals of borrowing companies deteriorate. We also retained about 9% of Fund assets in high-yield bonds. Those bonds generally helped performance for the period, especially when the market for bank loans became volatile in July and August. Performance was held back very early in the Fund's life because of the typical delay in investing in bank loans. Whereas money can be invested in bonds very quickly, it takes more than a week to complete an investment in a bank loan purchased in the secondary market to begin earning interest. It can take up to three weeks for a new issue purchase to close before earning interest. Assets were held in cash, which pays lower interest, while they were waiting to be invested in loans. In addition, the exposure to high-yield bonds detracted from results when the high-yield market slumped in June. Overall, though, investments in high-yield bonds generally helped performance. 6 Pioneer Floating Rate Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- Q: What is your investment outlook? A: While we see the potential for some continued instability in the market because of supply/demand imbalance for bank loans, we anticipate that conditions should begin to stabilize in the first quarter of 2008. We anticipate that new loans entering the market in 2008 are likely to have stronger covenants to protect investors and are likely to have higher credit spreads - or yield premiums - reflecting both the supply/demand imbalance as well as the potential for increased defaults. In the meantime, investors in bank loans are being well compensated with competitive income for their investments, and default rates on the loans remain very low by historical measures. We believe the Fund is well positioned for a market that has evolved in recent months to become a buyer's market favoring investors in bank loans. 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 means that the Fund 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 this type of 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 7 Pioneer Floating Rate Fund - -------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 10/31/07 (continued) - -------------------------------------------------------------------------------- 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.

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, 2007 through October 31, 2007. Share Class A C Y - -------------------------------------------------------------------------------- Beginning Account Value $1,000.00 $1,000.00 $1,000.00 On 5/1/07 Ending Account Value $1,000.59 $ 997.52 $1,000.89 (after expenses) On 10/31/07 Expenses Paid During Period* $ 5.55 $ 10.07 $ 5.60 * Expenses are equal to the Fund's annualized expense ratio of 1.10%, 2.00%, and 1.11%, 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 partial year period). 14 Pioneer Floating Rate Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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 - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 10/31/07 - -------------------------------------------------------------------------------- 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. 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 prospectus(es) contains information regarding the 31 Pioneer Floating Rate Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 10/31/07 (continued) - -------------------------------------------------------------------------------- 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: 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. 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, 2007, the fund held no fair valued securities. 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 32 Pioneer Floating Rate Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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. 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, 2007, the Fund had a net capital loss carryforward of $132,347, which will expire in 2015 if not utilized. At October 31, 2007, the Fund reclassified $34,035 to increase undistributed net investment income, $2,986 to increase accumulated net realized loss on investments and $31,049 to decrease paid in capital 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. The tax character of distributions paid during the period ended October 31, 2007 was as follows: 2007 ---------- Distributions paid from: Ordinary Income $1,221,099 ---------- Total $1,221,099 ========== 33 Pioneer Floating Rate Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 10/31/07 (continued) - -------------------------------------------------------------------------------- The following shows the components of distributable earnings on a federal income tax basis at October 31, 2007: 2007 --------- Undistributed ordinary income $ 407,239 Dividends payable (244,742) Capital loss carryforward (132,347) Unrealized depreciation (940,842) --------- Total $(910,692) ========= The difference between book basis and tax basis unrealized appreciation is attributable to the tax treatment of premium. 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 UniCredito Italiano S.p.A (UniCredito Italiano), earned no underwriting commissions on the sale of Class A shares during the period ended October 31, 2007. 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 34 Pioneer Floating Rate Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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 UniCredito Italiano, 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 period ended October 31, 2007, the net management fee was equivalent to 0.60% 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 to Class A shares and Class C shares, respectively. 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 $544 in management fees, administrative costs and certain other services payable to PIM at October 31, 2007. 35 Pioneer Floating Rate Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 10/31/07 (continued) - -------------------------------------------------------------------------------- 3. Unfunded Loan Commitments As of October 31, 2007, the Fund had unfunded loan commitments of approximately $489,299 (excluding unrealized depreciation on those commitments of $22,522 as of October 31, 2007) 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 $ 30,936 Fontainebleau Las Vegas, LLC, Delayed Draw Term Loan $166,667 HUB International, Ltd., Delayed Draw Term Loan $ 62,673 New World Gaming Partners Holdings, Ltd., Delayed Draw Term Loan $ 83,325 NRG Energy, Inc., Delayed Draw Term Loan $ 91,925 Sun Healthcare Group, Inc., Delayed Draw Term Loan $ 34,482 Telesat Canada, Delayed Draw Term Loan $ 19,291 4. Transfer Agent PIMSS, a wholly owned indirect subsidiary of UniCredito Italiano, 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 $358 in transfer agent fees payable to PIMSS at October 31, 2007. 5. Distribution and Service Plans The Fund adopted Plans of Distribution with respect to each class of shares except Class Y shares (Class A Plan and Class C Plan) in accordance with Rule 12b-1 of the Investment Company Act of 1940. Currently under the Class A Plan, PFD is reimbursed for distribution expenses in an amount up to 0.25% of the Fund's average daily net assets attributable to Class A shares. Pursuant to the Class C Plan, the Fund pays PFD 1.00% of the average daily net assets attributable to Class C shares. The fee 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 36 Pioneer Floating Rate Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- the Statement of Assets and Liabilities is $377 in distribution fees payable to PFD at October 31, 2007. 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%. Proceeds from the CDSCs are paid to PFD. For the period ended October 31, 2007 no CDSCs were paid to PFD. 6. 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 period ended October 31, 2007, the Fund's expenses were reduced by $60 under such arrangements. 7. New Pronouncements On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN 48 provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to determine whether the tax positions have a "more-likely-than-not" probability of being sustained by the applicable tax authority. Tax positions deemed to not meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the reporting period in which they are realized. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of no later than April 30, 2008. At this time, management is evaluating the implications of FIN 48 and any impact in the financial statements has not yet been determined. 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 37 Pioneer Floating Rate Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 10/31/07 (continued) - -------------------------------------------------------------------------------- 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. ADDITIONAL INFORMATION (unaudited) The qualified interest income percentage, which represents the portion of the Fund's ordinary income that is exempt from nonresident alien tax withholding, is 89.88% for the period ended October 31, 2007. 38 Pioneer Floating Rate Fund - -------------------------------------------------------------------------------- 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, 2007, and the related statement of operations, the statement of changes in net assets, and the financial highlights for the period from February 14, 2007 (Commencement of Operations) to October 31, 2007. 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 audit. We conducted our audit 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 audit 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, 2007, 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 audit 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, 2007, the results of its operations, the changes in its net assets, and the financial highlights for the period from February 14, 2007 (Commencement of Operations) to October 31, 2007, in conformity with U.S. generally accepted accounting principles. /s/ Ernst & Young LLP Boston, Massachusetts December 14, 2007 39 Pioneer Floating Rate Fund - -------------------------------------------------------------------------------- TRUSTEES, OFFICERS AND SERVICE PROVIDERS - -------------------------------------------------------------------------------- Investment Adviser Pioneer Investment Management, Inc.

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.
