They are particularly useful guides to keep in mind today, at a time when markets around the globe are being buffeted by problems in the financial and real estate industries and by concerns about a slowing economy. After an extended period of steady economic growth with sustained low unemployment and low inflation, the U.S. economy ran into difficulty as 2007 drew to a close. Investors in subprime mortgages were forced to mark down the value of their assets, imperiling leveraged balance sheets. The ensuing credit crunch forced central banks in the United States and Europe to assume the role of "lender of last resort" to keep credit markets functioning. Conditions worsened in the first quarter of 2008, as falling prices, margin calls and deleveraging continued, the auction-rate preferred market seized up. The U.S. Federal Reserve expanded its lender-of-last-resort role to include lending to primary dealers and continued to cut interest rates. By then, recession talk was widespread as concern grew that falling home prices, rising unemployment, sharply rising food and energy prices, and disruptions in financial markets posed a significant threat to economic growth. Markets reacted poorly to the developments leading up to the difficulties surrounding Bear Stearns, with fixed-income credit spreads (the difference in rates between corporate and U.S. government bonds) widening dramatically and stock markets declining, wiping out the positive returns markets had delivered in the preceding year. Treasury bond prices rose as the market underwent a flight to quality. In the six weeks between the Bear Stearns problems and the end of April, though, there were no further market crises, recession fears faded in light of positive economic news, and stock markets rallied, recouping some of their first-quarter losses, while Treasury bond prices fell back. Over the six-month period ending April 30, 2008, the Dow Jones Industrial Average fell 7%, the Standard & Poor's 500 Index fell 10% and the NASDAQ Composite Index fell 16%. The MSCI EAFE Developed Market Index of international stock markets fell 9%, and the MSCI Emerging Markets Index fell 10% over the same period. The U.S. investment-grade bond market, as measured by the Lehman 2 Letter Brothers Aggregate Bond Index, was a solid performer over the six-month period, rising 4%. The U.S. high-yield bond market, as measured by the Merrill Lynch High Yield Bond Master II Index, fell 1% over the six months as its higher-coupon yields could not offset a fall in bond prices triggered by widening credit spreads. Looking forward, the risk of a 2008 recession seems diminished, but substantial risks remain in both financial markets and the real economy. On the other hand, a weak U.S. dollar and substantial fiscal and monetary stimulus are potent support for the economy. Markets remain volatile, and falling risk tolerances and deleveraging may depress asset prices in the short term, but equity and corporate bond valuations look attractive over a longer time horizon unless the U.S. economy falls into a severe and protracted recession. Sudden swings in the markets are always to be expected, but they are difficult to time. Maintaining a long-term time horizon, being diversified, and paying attention to asset allocation are important investment principles. 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 and to adhere to a strategic plan rather than letting emotion drive investment decisions.

In the face of declining investor demand, the values of many loans fell during the period despite a resurgence in the final month of the period. In the following interview, Jonathan Sharkey discusses the factors that affected the performance of Pioneer Floating Rate Fund during the six-month period ended April 30, 2008. 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 during the six months ending April 30, 2008? A: Pioneer Floating Rate Fund's Class A shares had a total return of -2.57%, at net asset value, over the six months. During the same period, the Lehman High Yield Loans Performing Index fell by -2.80% while the average return of the 78 mutual funds in Lipper's Loan Participation category was -3.52%. On April 30, 2008, the 30-day SEC yield of the Fund's Class A shares was 4.69%. 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 six months ending April 30, 2008? A: Problems that began with weakness in subprime mortgages undermined the performance of floating rate loans as well as other credit-sensitive income investments during the period. The downward spiral in prices was most severe during the first three months of 2008, when the Lehman High Yield Leveraged Loan Index fell by 5.53%, the worst drop in its history. As fears about the credit markets widened, many investors sold their loan investments while others, who had borrowed money to make investments, found their access to additional money restricted. 4 Pioneer Floating Rate Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- To stabilize the markets, the U.S. Federal Reserve intervened by lowering the key Fed funds rate and embarking on a series of other policy initiatives to add liquidity to the financial markets. Between September 2007 and April 30, 2008, the Federal Reserve cut the Fed funds rate from 5.25% to 2.00% and announced a series of policies designed to encourage more lending activity and forestall a deep economic slump. In March 2008, the Federal Reserve also helped arrange the rescue of the faltering investment bank Bear Stearns by JP Morgan Chase and opened up lending facilities to investment banks. The actions of the Federal Reserve led to a sharp comeback by bank loans and other credit-sensitive investments in the closing weeks of the period. The Lehman High Yield Leveraged Loan Index, for example, rose by 4.14% in April 2008, yet the resurgence was not enough to overcome the effects of the Fund's losses in the middle of the six-month period ending April 30, 2008. Q: What factors helped the Fund outperform its Lehman index as well as its Lipper peer group average? A: The Fund held up relatively well because we had positioned the portfolio conservatively, with an average credit rating on the Fund's investments of BB-, compared with an average rating of B in the Lehman index. Over the six months, we widened the portfolio's diversity, investing whenever possible in a greater number of different loans to reduce the exposure to any potential problems in specific loans. Over the period, we increased the number of names in the portfolio from 75 to 92. The Fund also focused on loans with solid covenant protection and emphasized loans to higher quality companies with good prospects. That led to outperformance during a difficult period for bank loan investing, especially during the difficult first quarter of 2008. However, we did have some disappointing investments. The Fund had a relatively large position, for example, in loans to Land Source, a venture backed by homebuilder Lennar and by the California Public Employees' Retirement System (CALPERS). The venture's securities encountered difficulty because of the seizing up of the credit markets in the face of deteriorating conditions in the California real estate market. Also detracting from results was the Fund's investment in loans to J.G. Wentworth, a specialty finance company whose principal business is packaging the rights 5 Pioneer Floating Rate Fund - -------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 4/30/08 (continued) - -------------------------------------------------------------------------------- to insurance settlements. While the underlying collateral for the loans remained solid, the problems in the credit markets made it difficult for the company to sell its loans to investors. Q: What is your investment outlook? A: We think there are attractive opportunities in the market for floating-rate loans, where investors are being compensated for having persevered through a difficult period. The sharp revival of loan values in April 2008 should encourage investors to move back into the market. Although conditions may continue to be volatile in the short term, attractive loans are available at significant discounts to our estimates of their underlying values, giving investors the potential for capital appreciation as the loans are eventually retired. In addition, new loans entering the market tend to be soundly structured, with relatively less debt and attractive yields. 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 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 6 Pioneer Floating Rate Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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, 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 November 1, 2007 through April 30, 2008.

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 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 prospectuses contain information regarding the 34 Pioneer Floating Rate Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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 April 30, 2008, the Fund held no fair valued securities. Temporary cash investments are valued at cost which approximates market value. 35 Pioneer Floating Rate Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 4/30/08 (unaudited) (continued) - -------------------------------------------------------------------------------- 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. All tax returns filed thus far 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. The tax character of current year distributions will be determined at the end of the fiscal year. 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 ========== - -------------------------------------------------------------------------------- 36 Pioneer Floating Rate Fund - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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 UniCredit S.p.A (UniCredit), earned $1,830 in underwriting commissions on the sale of Class A shares during six months ended April 30, 2008. 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 37 Pioneer Floating Rate Fund - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 4/30/08 (unaudited) (continued) - -------------------------------------------------------------------------------- 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.

These expense limitations are in effect through March 1, 2011 for Class A shares and through March 1, 2009 for Class C shares.

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.
