We have been cautiously optimistic about the U.S. from the start of the year, and the economic data continue to be encouraging. The housing and auto sectors are benefitting from record-low interest rates. The climate for consumer and business credit has improved, and inflation appears to be subdued. While corporate profits slowed in the third quarter, many U.S. companies continue to have strong balance sheets and to pay attractive dividends* compared to fixed-income securities. All of these factors contributed to gains for investors who owned riskier assets, including equities and higher-yielding corporate bonds. Year to date through the end of the third quarter, the Standard & Poor's 500 Index returned 16.35%. In fixed income, the Bank of America Merrill Lynch High Yield Master II Index was up by 12.02% during the same period, while the Barclays Capital Aggregate Bond Index gained 3.99%. Treasury bonds, by contrast, generated a comparatively sluggish return of 1.70%, as measured by the Barclays Capital Intermediate Treasuries Index. Despite this generally positive picture during the first three quarters of 2012, investors face powerful macroeconomic challenges in the months ahead. These include the threat of a so-called "fiscal cliff" in the U.S. budget process after the November elections, the European sovereign-debt crisis, and slowing growth in both Europe and China. Investors can continue to count on market volatility tied to these factors, although we remain optimistic that the underlying economic trends are moving in the right direction. At Pioneer, we have long advocated the benefits of staying diversified** and investing for the long term. And while diversification alone does not assure a profit or protect against loss in a declining market, we believe in actively seeking out opportunities in undervalued securities and sectors around the globe. 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. * Dividends are not guaranteed. ** Diversification does not assure a profit or protect against loss in a declining market. 2 Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/12 Pioneer's investment professionals focus on finding good opportunities in both equity and bond markets using the same disciplined investment approach we have used since 1928. Our strategy is to identify undervalued individual securities with the greatest potential for success, carefully weighing risk against reward. Our teams of investment professionals continually monitor and analyze the relative valuations of different sectors and securities globally to help build portfolios that we believe can help you achieve your investment goals.

Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/12 3 Portfolio Management Discussion | 10/31/12 In the following discussion, Michele Garau reviews the factors that affected the performance of Pioneer Multi-Asset Real Return Fund during the 12-month period ended October 31, 2012. Mr. Garau, vice president and portfolio manager at Pioneer, is responsible for the day-to-day management of the Fund. Q How did the Fund perform during the 12-month period ended October 31, 2012? A Pioneer Multi-Asset Real Return Fund's Class A shares returned 8.01% at net asset value during the 12-month period ended October 31, 2012, while the Fund's benchmark, the Barclays Capital U.S. Treasury TIPS 1-10 Year Index (the Barclays Index), returned 5.17%. During the same period, the average return of the 196 mutual funds in Lipper's Flexible Portfolio Funds category was 6.31%. Q Could you review the Fund's general investment approach and its positioning as of October 31, 2012? A The Fund seeks to generate real return--or, in other words, a return in excess of inflation--across a full range of economic scenarios. While many "real return" portfolios focus exclusively on hard assets (such as gold, commodities, oil, and real estate) and/or Treasury Inflation Protected Securities ("TIPS"), we believe a diversified*, flexible approach that allocates among real assets and traditional financial assets, such as stocks and bonds, may yield better long-term results. We believe the Fund's opportunistic, "go anywhere" investment philosophy provides a greater degree of latitude to achieve positive real returns over time, no matter what the level of inflation. As of October 31, 2012, approximately 65% of the portfolio's assets were invested in equities, 30% of assets were held in fixed-income investments, 2% of assets were held in commodities and real estate, with the remainder allocated to cash. Q How did the Fund's equity positioning affect performance during the 12-month period ended October 31, 2012, and how is the Fund positioned within the asset class? A The Fund's stock allocation performed well and aided performance during the 12-month period, reflecting the strength of the broader global markets as well as our emphasis in the portfolio on stocks with earnings visibility, robust free cash flows and safe, attractive dividend** yields. We have found * Diversification does not assure a profit or protect against loss in a declining market. ** Dividends are not guaranteed. 4 Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/12 many such opportunities in the consumer staples, health care and European insurance sectors, all of which are well-suited to our buy-and-hold approach for the portfolio's stock positions. As the Fund's broader asset allocation would suggest, we continue to favor stocks over bonds. One reason for this view is the fact that dividend yields on stocks remain at very attractive historical levels relative to the yields available on bonds. We also have been seeing a sort of disconnect in investor attitudes: although bond prices have surged in recent years, investors continue to use the asset class as a "safe haven." When the vast majority of investors conclude that an asset class is "safe," however, that often serves as a cue to begin looking for opportunities elsewhere. And right now, we have been seeing better values in global equities--an asset class where returns have been dampened by macroeconomic concerns-- than in bonds that continue to offer historically low yields. Not all areas of the stock market are equally attractive, however, and as a result, we made a notable adjustment to the geographical weightings of the Fund's equity allocation during the past 12 months. Since the Fund was launched in 2010, we have managed the equity portion of the portfolio with an approximate target of having one-third of assets in domestic stocks, one-third in developed-market international stocks, and one-third in the emerging markets. Currently, however, we have been seeing a less- compelling risk/reward picture in U.S. equities due to the risks associated with the country's rising debt and the looming combination of tax increases and spending cuts known as the "fiscal cliff," which is due to hit in January 2013 unless a deal can be struck in Washington. We decided, therefore, to decrease the Fund's equity weighting in the United States and increase its weighting in the other two regions. Investors may wonder why we would boost the Fund's weighting in developed-market international equities given the continued debt problems and sluggish economic growth in Europe and Japan. The short answer is that the Fund's holdings are of global companies, such as Michelin or Nestle, that just happen to be domiciled in those regions. The performance of such stocks is more dependent on their own company-specific fundamentals than on the economic trends in their home countries. In the emerging markets, we continue to focus the Fund's investments in Asian countries, with an emphasis on the Philippines, Indonesia, Singapore, Malaysia and Thailand. We also have established a position in Latin America. While the Fund had not previously held Latin American assets since its inception, we believe the region offers some compelling investment ideas. Mexico, for instance, features limited government debt, a healthy banking sector, and a strong employment market stemming from the Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/12 5 country's improving wage competitiveness relative to China. Brazil, too, offers opportunities due to the growing wealth of the middle class. Latin American stocks remain a relatively small allocation within the Fund, but we believe they help to augment the overall diversification of the portfolio. Q Did the use of options and other derivative investments have a material effect on the Fund's performance during the 12 months ended October 31, 2012? A The Fund uses options, derivatives and other strategies as hedge positions, with the goal of seeking to mitigate risk and volatility within the portfolio. Examples of these include VIX options (Chicago Board Options Exchange Volatility Index), "short" equity positions, exchange-traded fund call options, and currency hedges, such as swaps and futures. During the 12-month period, the Fund's hedge positions succeeded in limiting the portfolio's volatility compared with the broader market and its competitors. Q Could you discuss the Fund's performance and positioning in the global bond markets during the 12-month period ended October 31, 2012. A The Fund's fixed-income weighting produced a healthy gain during the 12-month period and helped to mitigate some of the volatility found in the global equity markets. Although we favor stocks over fixed income in assembling the portfolio, we have continued to find pockets of opportunity in the bond market. In addition, we believe it's essential to maintain a position in the asset class in order to augment the Fund's diversification and to help smooth out overall performance. The Fund's fixed-income allocation is largely focused on corporate bonds issued by companies both in the United States and the emerging markets as well as the sovereign debt of smaller economies such as the Philippines, Mexico, Chile and Ireland. The portfolio also holds a modest position in U.S. Treasury Inflation Protected Securities, or TIPS. While TIPS currently do not offer exceptional value, they do provide the portfolio with a measure of inflation protection. In addition, they offer a "hedge" against potential disruptions in the global economy, and they do so at a better value than plain-vanilla U.S. Treasury securities. Overall, however, we have not been finding an abundance of fixed-income opportunities given that the yields on government bonds have been at such low levels. Q Could you discuss the Fund's commodity positioning as of October 31, 2012? A The Fund's 1% of the total investment portfolio allocation to commodities as of the end of the fiscal year was lower than it had been earlier in the reporting period, and far below where it stood two years ago. While the supply-and-demand fundamentals for most commodities remain relatively sound, we do not foresee the kind of aggressive stimulus from China that 6 Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/12 fueled strong gains for commodities during the period between 2009 and 2011. In addition, we don't expect the type of U.S. dollar weakness that would help support meaningful outperformance for commodities. We are, therefore, maintaining only a small allocation to the asset class in the portfolio at the present time, with 0.8% of the Fund's assets in gold and 0.2% in palladium. Q Do you have any closing thoughts for investors? A While the term "real return" is associated with funds whose primary goal is to outpace the rate of inflation, we view Pioneer Multi-Asset Real Return Fund as being more "opportunistic" in nature. In other words, our objective isn't merely to have the Fund's return outpace inflation; we also seek to take advantage of the most compelling opportunities across the financial markets, no matter what the rate of inflation. In that vein, we seek to provide positive Fund returns not just during periods of inflation, but also if deflation and/or disinflation conditions were to develop. We believe the Fund's ability to invest anywhere in the world, and across the full range of asset classes, can help it to achieve these objectives over time. Please refer to the Schedule of Investments on pages 17-30 for a full listing of Fund securities. All investments are subject to risk, including the possible loss of principal. Pioneer Multi-Asset Real Return ("MARR") Fund has the ability to invest in a wide variety of securities and asset classes. In addition, the Fund is non-diversified, which means it can invest a higher percentage of its assets in the securities of any one or more issuers. This will increase the Fund's potential risk exposure. The Fund may invest in underlying funds (ETFs and unit investment trusts). In addition to the Fund's operating expenses, you will indirectly bear the operating expenses of investments in any underlying funds. The Fund and some of the underlying funds employ leverage, which increases the volatility of investment returns and subjects the Fund to magnified losses if an underlying fund's investments decline in value. The Fund and some of the underlying funds may use derivatives, such as options and futures, which can be illiquid, may disproportionately increase losses, and have a potentially large impact on Fund performance. The Fund and some of the underlying funds may employ short selling, a speculative strategy. Unlike the possible loss on a security that is purchased, there is no limit on the amount of loss on an appreciating security that is sold short. Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/12 7 The Fund may invest in inflation-linked securities. As inflationary expectations increase, inflation-linked securities may become more attractive, because they protect future interest payments against inflation. Conversely, as inflationary concerns decrease, inflation-linked securities will become less attractive and less valuable. The Fund may invest in credit default swaps, which may in some cases be illiquid, and they increase credit risk since the fund has exposure to both the issuer of the referenced obligation and the counterparty to the credit default swap. The Fund may invest in subordinated securities which may be disproportionately adversely affected by a default or even a perceived decline in creditworthiness of the issuer. The Fund may invest in floating rate loans. The value of collateral, if any, securing a floating rate loan can decline or may be insufficient to meet the issuer's obligations or may be difficult to liquidate. The Fund may invest in event-linked bonds. The return of principal and the payment of interest on event-linked bonds are contingent on the non-occurrence of a pre-defined "trigger" event, such as a hurricane or an earthquake of a specific magnitude. The Fund may invest in commodities. The value of commodity-linked derivatives may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, factors affecting a particular industry or commodity, international economic, political and regulatory developments, supply and demand, and governmental regulatory policies. Investments in equity securities are subject to price fluctuation. Small-and mid-cap stocks involve greater risks and volatility than large-cap stocks. International investments are subject to special risks, including currency fluctuations, and social, economic and political uncertainties, which could increase volatility. These risks are magnified in emerging markets. Investments in fixed-income securities involve interest rate, credit, inflation, and reinvestment risks. As interest rates rise, the value of fixed-income securities falls. The Fund may invest in mortgage-backed securities, which during times of fluctuating interest rates may increase or decrease more than other fixed- income securities. Mortgage-Backed securities are also subject to prepayments. Prepayment risk is the chance that mortgage-backed bonds will be paid off early if falling interest rates prompt homeowners to refinance their mortgages. 8 Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/12 High-yield bonds possess greater price volatility, illiquidity, and possibility of default. There is no assurance that these and other strategies used by the Fund or underlying funds will be successful. These risks may increase share price volatility.

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.

These combined ratios were multiplied by the average account value over the period, and then multiplied by 184/366 (to reflect the one-half year period) to calculate the "Expenses Paid During Period" in the table above. Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/12 15 Hypothetical Example for Comparison Purposes The table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads) that are charged at the time of the transaction. Therefore, the table below is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher.

Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/12 37 Notes to Financial Statements | 10/31/12 (Consolidated) 1. Organization and Significant Accounting Policies Pioneer Multi-Asset Real Return Fund (the Fund) is one of two portfolios comprising 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 Fund's investment objective is to seek total return. 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 May 3, 2010. 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. 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. 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: 38 Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/12 A. Security Valuation Security transactions are recorded as of trade date. The net asset value of the Fund is computed once daily, on each day the New York Stock Exchange (NYSE) is open, as of the close of regular trading on the NYSE. 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 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. Short-term fixed income securities with remaining maturities of sixty days or less generally are valued at amortized cost. Shares of money market mutual funds are valued at their net asset value. Trading in foreign securities is substantially completed each day at various times prior to the close of the NYSE. The values of such securities used in computing the net asset value of the Fund's shares are determined as of such times. Securities or loan interests for which independent pricing services are unable to supply prices or for which market prices and/or quotations are not readily available or are considered to be unreliable are valued by or at the direction or with the approval of the Valuation Committee using fair value methods pursuant to procedures adopted by the Board of Trustees. The Valuation Committee is comprised of certain members of the Board of Trustees. The Fund may use fair value methods if it is determined that a significant event has occurred after the close of the exchange or market on which the security trades and prior to the determination of the Fund's net asset value. Examples of a significant event might include political or economic news, corporate restructurings, natural disasters, terrorist activity or trading halts. Thus, the valuation of the Fund's securities may differ significantly from exchange prices and such differences could be material. PIM is responsible for monitoring developments that may impact fair valued securities and for discussing and assessing fair values on an ongoing basis, and at least quarterly, with the Valuation Committee. Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/12 39 At October 31, 2012, no securities were valued using fair value methods (other than securities valued using prices supplied by independent pricing services). Inputs used when applying fair value methods to value a security may include credit ratings, the financial condition of the company, current market conditions and comparable securities. 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/premiums on debt securities are accreted/amortized for financial reporting purposes over the life of the respective securities, and such accretion/amortization is included in interest income. 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. Interest income is recorded on the accrual basis. All discounts/premiums on debt securities are accreted/amortized into interest income for financial reporting purposes. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. B. Foreign Currency Translation The books and records of the Fund are maintained in U.S. dollars. Amounts denominated in foreign currencies are translated into U.S. dollars using current exchange rates. Net realized gains and losses on foreign currency transactions, if any, represent, among other things, the net realized gains and losses on foreign currency contracts, disposition of foreign currencies and the difference between the amount of income accrued and the U.S. dollars actually received. Further, the effects of changes in foreign currency exchange rates on investments are not segregated in the statement of operations from the effects of changes in market price of those securities but are included with the net realized and unrealized gain or loss on investments. 40 Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/12 C. Futures Contracts The Fund may enter into futures transactions to hedge against changes in interest rates, securities prices and currency exchange rates or to seek to increase total return. Futures contracts are types of derivatives. All futures contracts entered into by the Fund are traded on a futures exchange. Upon entering into a futures contract, the Fund is required to deposit with a broker an amount of cash or securities equal to the minimum "initial margin" requirements of the associated futures exchange. Subsequent payments for futures contracts ("variation margin") are paid or received by the Fund, depending on the daily fluctuation in the value of the contracts, and are recorded by the Fund as unrealized gains or losses. When the contract is closed, the Fund realizes a gain or loss equal to the difference between the opening and closing value of the contract as well as any fluctuation in foreign currency exchange rates where applicable. Futures contracts are subject to market risk, interest rate risk and currency exchange rate risk. Changes in value of the contracts may not directly correlate to the changes in value of the underlying securities. These risks may decrease the effectiveness of the Fund's hedging strategies and potentially result in a loss. With futures, there is minimal counterparty credit risk to the Fund since futures are exchange-traded and the exchange's clearinghouse, as counterparty to all exchange-traded futures, guarantees the futures against default. The average number of contracts open during the year ended October 31, 2012 was 702. At October 31, 2012, open futures contracts were as follows: ----------------------------------------------------------------------------------- Number of Unrealized Contracts Settlement Appreciation/ Type Long/(Short) Month Value (Depreciation) ----------------------------------------------------------------------------------- CBOE VIX Future 434 11/12 $ 8,224,300 $ 390,773 CBOE VIX Future (345) 2/13 (7,314,000) 503,251 U.S. Ultra Bond CBT 77 12/12 12,712,219 197,547 S&P500 EMINI Future (330) 12/12 (23,211,375) (32,218) Dollar Index Future 314 12/12 25,115,918 (18,096) ----------------------------------------------------------------------------------- $ 15,527,062 $ 1,041,257 =================================================================================== D. Forward Foreign Currency Contracts The Fund may enter into forward foreign currency contracts (contracts) for the purchase or sale of a specific foreign currency at a fixed price on a future date. All contracts are marked to market daily at the applicable exchange rates, and any resulting unrealized gains or losses are recorded in the Fund's financial statements. The Fund records realized gains and losses at the time a portfolio hedge is offset by entry into a closing transaction or extinguished by delivery of the currency. Risks may arise upon entering into these contracts from the potential inability of counterparties to meet the terms of the contract and from unanticipated movements in the value of foreign currencies relative to the U.S. dollar (see Note 6). Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/12 41 E. 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. As of October 31, 2012, the Fund did not have any interest and penalties related to unrecognized tax positions, which, if applicable, would be recorded as an income tax expense in the Statement of Operations. Tax years remain subject to examination by federal and state 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, 2012, the Fund reclassified $4,782,328 to decrease paid-in capital, $3,646,829 to increase distributions in excess of net investment income, and $8,429,157 to decrease 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, 2012, the Fund was permitted to carry forward indefinitely $4,216,831 of short-term losses under the Regulated Investment Company Modernization Act of 2010 without limitation. Additionally, at October 31, 2012, the Fund had a net capital loss carryforward of $541,921 of which the following amounts will expire in 2018 and 2019 if not utilized: $53,013 in 2018 and $488,908 in 2019. Since new losses are required to be utilized prior to losses incurred in pre-enactment tax years, pre-enactment capital loss carryforwards may be more likely to expire unused. The tax character of distributions paid during the years ended October 31, 2012 and October 31, 2011 was as follows: ----------------------------------------------------------------------------------- 2012 2011 ----------------------------------------------------------------------------------- Distributions paid from: Ordinary income $10,476,948 $825,872 ----------------------------------------------------------------------------------- Total $10,476,948 $825,872 =================================================================================== 42 Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/12 The following shows the components of distributable earnings on a federal income tax basis at October 31, 2012: ----------------------------------------------------------------------------------- 2012 ----------------------------------------------------------------------------------- Distributable earnings: Capital loss carryforward $ (4,758,752) Net unrealized gain 39,955,413 ----------------------------------------------------------------------------------- Total $ 35,196,661 =================================================================================== The difference between book-basis and tax-basis net unrealized gain is attributable to the tax deferral of losses on wash-sales, the tax treatment on passive foreign investment company (PFIC) holdings, adjustments relating to catastrophe bonds, tax basis adjustments on partnerships and the mark-to-market of forward currency and future contracts. F. 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 $59,802 in underwriting commissions on the sale of Class A shares during the year ended October 31, 2012. G. 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). 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. Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/12 43 H. Risks Investing in foreign and/or emerging markets securities involves risks relating to interest rates, currency exchange rates and economic and political conditions. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making the Fund more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. The Fund's prospectus contains unaudited information regarding the Fund's principal risks. Please refer to that document when considering the Fund's principal risks. The Fund may gain exposure to commodities (such as oil and precious metals) through investment in commodity-related investments, including commodity-linked derivatives, ETFs and leveraged or unleveraged commodity-linked notes (derivative debt instruments with principal and/or coupon payments linked to the performance of commodity indices). The Fund also may invest in equity securities of issuers in commodity-related industries. The Fund's investments in commodity-related investments may subject the Fund to greater market price volatility than investments in traditional securities. The value of commodity-related investments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting particular industries or commodities, such as weather, disease, embargoes, acts of war or terrorism, or political and regulatory developments. Commodity-related investments may be more volatile than the underlying commodities. In addition, commodity-linked investments are subject to counterparty risk due to there being a relatively small number of issuers. The Fund gains exposure to commodity-related investments by investing in the Pioneer Cayman Commodity Fund, Ltd. (the Subsidiary), a foreign entity that is treated as a controlled foreign corporation for U.S. federal income tax purposes. The Fund may invest up to 25% of its total assets in the Subsidiary. The Fund's ability to invest in commodity-related investments, and the means through which any such investments may be made, is limited by tax considerations. The Fund may invest in REIT securities, the value of which can fall for a variety of reasons, such as declines in rental income, fluctuating interest rates, poor property management, environmental liabilities, uninsured damage, increased competition, or changes in real estate tax laws. 44 Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/12 I. 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. J. Securities Lending The Fund may lend securities in its portfolio to certain broker-dealers or other institutional investors. When entering into a securities loan transaction, the Fund typically receives cash collateral from the borrower equal to at least the value of the securities loaned, which is invested in temporary investments. Credit Suisse AG, New York Branch, as the Fund's securities lending agent, manages the Fund's securities lending collateral. The income earned on the investment of collateral is shared with the borrower and the lending agent in payment of any rebate due to the borrower with respect to the securities loan, and in compensation for the lending agent's services to the Fund. The Fund also continues to receive payments in lieu of dividends or interest on the securities loaned. Gain or loss on the value of the loaned securities that may occur during the term of the loan will be for the account of the Fund. The amount of the collateral is required to be adjusted daily to reflect any price fluctuation in the value of the loaned securities. If the required market value of the collateral is less than the value of the loaned securities, the borrower is required to deliver additional collateral for the account of the Fund prior to the close of business on that day. The Fund has the right, under the lending agreement, to terminate the loan and recover the securities from the borrower with prior notice. The Fund is required to return the cash collateral to the borrower and could suffer a loss if the value of the collateral, as invested, has declined. As of May 8, 2012, the Pioneer funds ended their involvement in the securities lending program. Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/12 45 K. Option Writing The Fund may buy and sell put and call options, or write put and covered call options on portfolio securities in order to produce incremental earning or protect against changes in the value of portfolio securities. The Fund generally purchases put options or writes covered call options to hedge against adverse movements in the value of portfolio holdings. When an option is written, the Fund receives a premium and becomes obligated to sell or purchase the underlying security at a fixed price, upon the exercise of the option. When the Fund writes an option, an amount equal to the premium received by the Fund is recorded as a liability and is subsequently adjusted to the current value of the option written. Premiums received from writing options that expire unexercised are treated by the Fund on the expiration date as realized gains from investments. The difference between the premium and the amount paid on effecting a closing purchase transaction, including brokerage commissions, is also treated as a realized gain, or, if the premium is less than the amount paid for the closing purchase transaction, as a realized loss. If a call option is exercised, the premium is added to the proceeds from the sale of the underlying security in determining whether the Fund has realized a gain or loss. The Fund as writer of an option bears the market risk of an unfavorable change in the price of the security underlying the written option. At October 31, 2012, there were no open written options. 46 Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/12 L. Purchased Options Purchased call and put options entitle the Fund to buy and sell a specified number of shares or units of a particular security, currency or index at a specified price at a specific date or within a specific period of time. Upon the purchase of a call or put option, the premium paid by the Fund is included in the Statement of Assets and Liabilities as an investment. All premiums are marked-to-market daily, and any unrealized gains or losses are recorded in the Fund's financial statements. As the purchaser of an index option, the Fund has the right to receive a cash payment equal to any depreciation in the value of the index below the strike price of the option (in the case of a put) or equal to any appreciation in the value of the index over the strike price of the option (in the case of a call) as of the valuation date of the option. Premiums paid for purchased calls and put options which have expired are treated as realized losses on investments in the Statement of Operations. Upon the exercise or closing of a purchased put option, the premium is offset against the proceeds on the sale of the underlying security or financial instrument in order to determine the realized gain or loss on investments. Upon the exercise or closing of a purchased call option, the premium is added to the cost of the security or financial instrument. The risk associated with purchasing options is limited to the premium originally paid. The average number of contracts open during the year ended October 31, 2012 was 3,455. Purchased option contracts outstanding at year end are listed at the end of the Fund's schedule of investments. 2. Management Agreement PIM, a wholly owned indirect subsidiary of UniCredit, manages the Fund's portfolio. Management fees are calculated daily at an annual rate of 0.70% of the average daily net assets of the Fund, excluding assets invested in the Subsidiary and on which the Subsidiary pays a management fee. The Subsidiary has entered into a separate management contract with PIM, pursuant to which PIM manages the assets of the Subsidiary. As compensation for its management services to the Subsidiary and expenses incurred with respect to the Subsidiary, the Subsidiary pays PIM a fee at the annual rate of 0.70% of the Subsidiary's average daily net assets. PIM has contractually agreed to limit ordinary operating expenses to the extent required to reduce Fund expenses to 1.20%, 2.10% and 0.90% of the average daily net assets attributable to Class A, Class C and Class Y shares, respectively. These expense limitations are in effect through March 1, 2014. Fees waived and expenses reimbursed during the year ended October 31, 2012 are reflected on the Statement of Operations. Fees and expenses of other investment companies in which the Fund may invest are not included in the Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/12 47 expense limitations noted above. There can be no assurance that PIM will extend the expense limitation agreement for a class of shares beyond the date referred to above. In addition, under the management and administration agreements, certain other services and costs, including accounting, regulatory reporting and insurance premiums, are paid by the Fund as administrative reimbursements. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $38,626 in management fees, administrative costs and certain other reimbursements payable to PIM at October 31, 2012. Effective March 5, 2012, PIM has retained Brown Brothers Harriman & Co. to provide certain sub-administration and accounting services to the Fund. 3. Transfer Agent PIMSS, a wholly owned indirect subsidiary of UniCredit, provides substantially all transfer agent and shareowner services to the Fund at negotiated rates. In addition, the Fund reimburses PIMSS for out-of-pocket expenses incurred by PIMSS related to shareholder communications activities such as proxy and statement mailings, outgoing phone calls and omnibus relationship contracts. For the year ended October 31, 2012, such out-of-pocket expenses by class of shares were as follows: ----------------------------------------------------------------------------------- Shareholder Communications: ----------------------------------------------------------------------------------- Class A $ 84,864 Class C 59,524 Class Y 104,885 ----------------------------------------------------------------------------------- Total $249,273 =================================================================================== Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $58,426 in transfer agent fees and out-of-pocket reimbursements payable to PIMSS at October 31, 2012. 4. Distribution Plan The Fund has adopted a Distribution Plan pursuant to Rule 12b-1 of the Investment Company Act of 1940 with respect to its Class A 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 48 Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/12 distribution services with regard to Class C shares. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $7,722 in distribution fees payable to PFD at October 31, 2012. In addition, redemptions of each class of shares (except Class Y shares) may be subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may be imposed on redemptions of certain net asset value purchases of Class A shares within 12 months of purchase. Redemptions of Class C shares within one year of purchase are subject to a CDSC of 1.00%, based on the lower of cost or market value of shares being redeemed. Shares purchased as part of an exchange remain subject to any CDSC that applied to the original purchase of those shares. There is no CDSC for Class Y shares. Proceeds from the CDSCs are paid to PFD. For the year ended October 31, 2012, CDSCs in the amount of $37,288 were paid to PFD. 5. Basis for Consolidation of the Financial Statements The consolidated financial statements of the Fund include the accounts of the Subsidiary. All intercompany accounts and transactions have been eliminated. The Subsidiary, a Cayman Islands exempted company, was incorporated on February 10, 2010 and is wholly-owned and controlled by the Fund. The Fund is the sole shareholder of the Subsidiary. It is intended that the Fund will remain the sole shareholder and will continue to control the Subsidiary. The Fund and the Subsidiary are both managed by PIM. The Subsidiary acts as an investment vehicle for the Fund in order to effect certain investments on behalf of the Fund. As of October 31, 2012, the Subsidiary represented $6,904,628 or approximately 1.58% of the net assets of the Fund. 6. Forward Foreign Currency Contracts At October 31, 2012, the Fund had entered into various forward foreign currency contracts that obligate the Fund to deliver or take delivery of currencies at specified future maturity dates. Alternatively, prior to the settlement date of a forward foreign currency contract, the Fund may close out such contract by entering into an offsetting contract.

Expense Offset Arrangements The Fund has entered into certain expense offset arrangements with PIMSS which may result in a reduction in the Fund's total expenses due to interest earned on cash held by PIMSS. For the year ended October 31, 2012, the Fund's expenses were not reduced under such arrangements. 8. Line of Credit Facility The Fund, along with certain other funds in the Pioneer Family of Funds (the Funds), participates in a committed, unsecured revolving line of credit facility. Borrowings are used solely for temporary or emergency purposes. The Fund may borrow up to the lesser of the amount available under the facility or the limits set for borrowing by the Fund's prospectus and the 1940 Act. The credit facility in effect until January 20, 2012 was in the amount of $165 million. Under such facility, interest on borrowings was payable at the higher of the London Interbank Offered Rate (LIBOR) on the borrowing date plus 1.25% on an annualized basis or the Federal Funds Rate on the borrowing date plus 1.25% on an annualized basis. The credit facility in effect as of February 15, 2012 is in the amount of $215 million. Under such facility, depending on the type of loan, interest on borrowings is payable at LIBOR plus 0.90% on an annualized basis, or the Alternate Base Rate, which is the greater of (a) the facility's administrative agent's daily announced prime rate on the borrowing date, (b) 2% plus the Federal Funds Rate on the borrowing date and (c) 2% plus the overnight Euro dollar rate on the borrowing date. The Funds pay an annual commitment fee to participate in a credit facility. The commitment fee is allocated among participating Funds based on an allocation schedule set forth in the credit agreement. For the year ended October 31, 2012, the Fund had no borrowings under a credit facility. 50 Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/12 9.

These financial statements and financial highlights are the responsibility of the Trust's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Trust'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 Trust'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, 2012, by correspondence with the custodian, brokers and agent banks. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the consolidated financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Pioneer Multi-Asset Real Return Fund at October 31, 2012, the consolidated results of its operations for the year then ended, the changes in its net assets for the two years in the period then ended, and the financial highlights for each of the periods indicated therein, in conformity with U.S. generally accepted accounting principles.

We have been cautiously optimistic about the U.S. from the start of the year, and the economic data continue to be encouraging. The housing and auto sectors are benefitting from record-low interest rates. The climate for consumer and business credit has improved, and inflation appears to be subdued. While corporate profits slowed in the third quarter, many U.S. companies continue to have strong balance sheets and to pay attractive dividends* compared to fixed-income securities. All of these factors contributed to gains for investors who owned riskier assets, including equities and higher-yielding corporate bonds. Year to date through the end of the third quarter, the Standard & Poor's 500 Index returned 16.35%. In fixed income, the Bank of America Merrill Lynch High Yield Master II Index was up by 12.02% during the same period, while the Barclays Capital Aggregate Bond Index gained 3.99%. Treasury bonds, by contrast, generated a comparatively sluggish return of 1.70%, as measured by the Barclays Capital Intermediate Treasuries Index. Despite this generally positive picture during the first three quarters of 2012, investors face powerful macroeconomic challenges in the months ahead. These include the threat of a so-called "fiscal cliff " in the U.S. budget process after the November elections, the European sovereign-debt crisis, and slowing growth in both Europe and China. Investors can continue to count on market volatility tied to these factors, although we remain optimistic that the underlying economic trends are moving in the right direction. At Pioneer, we have long advocated the benefits of staying diversified** and investing for the long term. And while diversification alone does not assure a profit or protect against loss in a declining market, we believe in actively seeking out opportunities in undervalued securities and sectors around the globe. 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. * Dividends are not guaranteed. ** Diversification does not assure a profit or protect against loss in a declining market. 2 Pioneer Floating Rate Fund | Annual Report | 10/31/12 Pioneer's investment professionals focus on finding good opportunities in both equity and bond markets using the same disciplined investment approach we have used since 1928. Our strategy is to identify undervalued individual securities with the greatest potential for success, carefully weighing risk against reward. Our teams of investment professionals continually monitor and analyze the relative valuations of different sectors and securities globally to help build portfolios that we believe can help you achieve your investment goals. 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 us.pioneerinvestments.com.

Pioneer Floating Rate Fund | Annual Report | 10/31/12 3 Portfolio Management Discussion | 10/31/12 The market remained strong for floating-rate bank loans during most of the 12-month period ended October 31, 2012, as investors sought out opportunities to gain yield in a low-interest-rate environment. During a period in which investors appeared more tolerant of taking on credit risk, lower-rated bank loans tended to outperform higher-rated securities. In the following interview, Jonathan Sharkey discusses the factors that affected the performance of Pioneer Floating Rate Fund during the 12-month period. Mr. Sharkey, vice president and a portfolio manager at Pioneer, is responsible for the daily management of the Fund. Q How did the Fund perform during the 12 months ended October 31, 2012? A Pioneer Floating Rate Fund's Class A shares returned 7.43% at net asset value during the 12 months ended October 31, 2012, while the Fund's benchmark, the Barclays Capital High Yield Loans Performing Index (the Barclays index), returned 8.73%. During the same 12-month period, the average return of the 156 mutual funds in Lipper's Loan Participating Funds category was 8.15%. Q Could you describe the investment environment for bank loans during the 12 months ended October 31, 2012? A Despite interim periods of worries about potential economic weakening that temporarily softened investor demand, the market for bank loans was positive during the 12 months ended October 31, 2012. The "risk-on" trade predominated during the period, with floating-rate bank loans producing solid returns. Lower-rated securities, including loans rated CCC and B, generated especially impressive results during the period, outperforming BB-rated loans. The reasons for the outperformance of lower-rated loans were many. One reason was that central banks throughout the world kept short-term interest rates very low. In the United States, for example, the Federal Reserve Board (the Fed) announced a third round of quantitative easing and said it intended to keep short-term interest rates at current low levels (between 0% and 0.25%). Overseas, the European Central Bank (ECB) moved to encourage lending activity, increase financial liquidity and reduce pressures on nations with sovereign-debt problems. In China, the central government cut interest rates and committed to expanding the nation's money supply. Meanwhile, investors' fears that some major economies might slip back into 4 Pioneer Floating Rate Fund | Annual Report | 10/31/12 recession abated during the period as more encouraging reports about job creation, the housing market, consumer sentiment and gross domestic product (GDP) trends began to emerge. As the myriad of positive factors emerged, investors' demand for floating- rate loans expanded during the 12-month period. High-yield bond mutual funds, for example, continued to add to their holdings in floating-rate loans because of the attractive values offered by loans compared with fixed- income corporate bonds--the latter often were selling at premiums to their par (face) values, while floating-rate loans were selling at discounts. A large portion of lower-quality loans were refinanced by high-yield bond issuance, and higher-quality loans were diverted to traditional bank lending. Additionally, CLOs (collateralized loan obligations), which represent nearly half of the loan investment universe, saw an unexpectedly large resurgence in new issuance and are on track to have 2012 become the third-largest year for new CLO issuance. Q How did you position the Fund in that environment and how did the positioning affect the Fund's performance during the 12 months ended October 31, 2012? A While the Fund produced solid returns during the full 12-month period, the return still trailed that of the benchmark Barclays Index, primarily due to the Fund's investment bias in favor of higher-quality bank loans. The tilt towards higher quality helped the Fund outperform during those months when the floating-rate loan market went down, but held back benchmark-relative results when the market rallied. During the 12-month period, we became more confident that the U.S. economy's underpinnings were holding up and thus became somewhat more aggressive and less defensive in the Fund's positioning. For example, we increased the portfolio's positions in more economically-sensitive sectors such as information technology and consumer loans, while reducing portfolio exposure to telecom services. At the same time, we maintained the Fund's higher-quality orientation. Accomplishing this became somewhat more challenging as the period progressed as the strong demand for loans encouraged some companies to issue more "covenant-light" loans, which offer less-strict covenant protection for investors than traditional loans. While we have not avoided having the Fund own such loans entirely, we have maintained the higher-quality bias and have worked to limit the percentage of Fund assets invested in covenant-light loans. Pioneer Floating Rate Fund | Annual Report | 10/31/12 5 Q What types of individual investments most affected the Fund's performance, either positively or negatively, during the 12 months ended October 31, 2012? A The Fund's better-performing loan investments during the period came from a variety of sectors and industries. One of the stronger individual performers in the portfolio during the period was Sun Health Care, an operator of long-term care facilities that was taken over by another company. Other solid performers held in the portfolio included loans to Aquilex, which provides maintenance and repair services to heavy industries; Ozburn-Hessey Logistics, which offers warehousing and distribution services to other companies; and credit card transaction processor First Data. The Fund also received good results from a small position in high-yield corporate bonds, which performed very well in an up-market. We have maintained the Fund's bond positions primarily for liquidity purposes. Notable among the more disappointing investments during the period was the only defaulted loan in the portfolio--a loan to Vertrue, which provides advertising and marketing services. Other poor-performing investments held in the portfolio during the period included loans to IAP Worldwide, a defense contractor that was hurt by redeployment of U.S. forces; and to Bumi Resources, a coal mining company whose debt was affected both by weakening demand for coal and by an internal corporate-governance issue. Q What is your investment outlook? A We continue to be optimistic about the prospects for bank-loan investments. Even after achieving strong performance over the past 12 months, bank loans still were selling at a discount to par value as of October 31, 2012. In contrast, fixed-income corporate bonds generally were selling at premiums to their par values. Moreover, we believe floating-rate bank loans still are priced attractively relative to their risk, especially when comparing loans' yield advantages over no-credit-risk alternatives such as U.S. Treasuries. Bank loans were selling at an implied default rate of about 5% as of October 31, 2012, while the actual forecasted default rate for bank loans for the next 12 months is at around 2%. (The long-term average default rate is about 3.5%.) 6 Pioneer Floating Rate Fund | Annual Report | 10/31/12 Given the Fed's announcement about not raising short-term rates until at least mid-2015, we believe that investors in floating-rate loans continue to be well compensated. In addition, whenever interest rates do rise, floating-rate loans typically offer more price protection than conventional, fixed-rate bonds. We think the financial health of corporate borrowers in the United States also makes a compelling argument for investing in bank loans, given that U.S. corporations, in general, are in solid financial shape and highly credit-worthy. Many U.S. corporations have continued to demonstrate healthy profit margins and strong balance sheets, and those factors should enable them to meet their credit obligations. Please refer to the Schedule of Investments on pages 16-43 for a full listing of Fund securities. Debt securities rated below investment grade are commonly referred to as "junk bonds" and are considered speculative. Below investment grade debt 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 may invest in high-yield securities of any rating, including securities that are in default at the time of purchase. Securities with floating interest rates generally are less sensitive to interest rate changes but may decline in value if their interest rates do not rise as much, or as quickly, as prevailing interest rates. Unlike fixed-rate securities, floating rate securities generally will not increase in value if interest rates decline. Changes in interest rates also will affect the amount of interest income the Fund earns on its floating rate investments. These risks may increase share price volatility. Past performance is no guarantee of future results, and there is no guarantee that market forecasts discussed will be realized. Any information in this shareholder report regarding market or economic trends or the factors influencing the Fund's historical or future performance are statements of opinion as of the date of this report.

Performance shown for Class Z shares for periods prior to the inception of Class Z shares on August 8, 2011, reflects the NAV performance of the Fund's Class A shares. The performance does not reflect differences in expenses, including the Rule 12b-1 fees applicable to Class A shares. Since fees for Class A shares are generally higher than those of Class Z shares, the performance for Class Z shares prior to their inception on August 8, 2011, would have been higher than the performance shown. Class Z shares are not subject to sales charges and are available for limited groups of eligible investors. All results are historical and assume the reinvestment of dividends and capital gains. Other share classes are available for which performance and expenses will differ. Performance results reflect any applicable expense waivers in effect during the periods shown.

Pioneer Floating Rate Fund | Annual Report | 10/31/12 13 Comparing Ongoing Fund Expenses As a shareowner in the Fund, you incur two types of costs: (1) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses; and (2) transaction costs, including sales charges (loads) on purchase payments. This example is intended to help you understand your ongoing expenses (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 at the beginning of the Fund's latest six-month period and held throughout the six months. Using the Tables -------------------------------------------------------------------------------- Actual Expenses The first table below provides information about actual account values and actual expenses. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period as follows: (1) Divide your account value by $1,000 Example: an $8,600 account value (divided by) $1,000 = 8.6 (2) Multiply the result in (1) above by the corresponding share class's number in the third row under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. Expenses Paid on a $1,000 Investment in Pioneer Floating Rate Fund Based on actual returns from May 1, 2012, through October 31, 2012. -------------------------------------------------------------------------------- Share Class A C Y Z -------------------------------------------------------------------------------- Beginning Account $1,000.00 $1,000.00 $1,000.00 $1,000.00 Value on 5/1/12 -------------------------------------------------------------------------------- Ending Account $1,031.20 $1,027.31 $1,033.17 $1,032.56 Value (after expenses) on 10/31/12 -------------------------------------------------------------------------------- Expenses Paid $5.67 $9.48 $3.58 $4.24 During Period* -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.11%, 1.86%, 0.70% and 0.83% for Class A, Class C, Class Y and Class Z shares, respectively, multiplied by the average account value over the period, multiplied by 184/366 (to reflect the one-half year period). 14 Pioneer Floating Rate Fund | Annual Report | 10/31/12 Hypothetical Example for Comparison Purposes The table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads) that are charged at the time of the transaction. Therefore, the table below is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher. Expenses Paid on a $1,000 Investment in Pioneer Floating Rate Fund Based on a hypothetical 5% return per year before expenses, reflecting the period from May 1, 2012, through October 31, 2012. -------------------------------------------------------------------------------- Share Class A C Y Z -------------------------------------------------------------------------------- Beginning Account $1,000.00 $1,000.00 $1,000.00 $1,000.00 Value on 5/1/12 -------------------------------------------------------------------------------- Ending Account $1,019.56 $1,015.79 $1,021.62 $1,020.96 Value (after expenses) on 10/31/12 -------------------------------------------------------------------------------- Expenses Paid $5.63 $9.42 $3.56 $4.22 During Period* -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.11%, 1.86%, 0.70% and 0.83% for Class A, Class C, Class Y and Class Z shares, respectively, multiplied by the average account value over the period, multiplied by 184/366 (to reflect the one-half year period).

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 diversified, open-end management investment company. The investment objective of the Fund is to produce a high level of current income. The Fund offers four classes of shares designated as Class A, Class C, Class Y and Class Z shares. Class A, Class C and Class Y shares were first publicly offered on February 14, 2007 and Class Z shares were first publicly offered on August 8, 2011. 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 or Class Z 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. 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: 52 Pioneer Floating Rate Fund | Annual Report | 10/31/12 A. Security Valuation Security transactions are recorded as of trade date. The net asset value of the Fund is computed once daily, on each day the New York Stock Exchange (NYSE) is open, as of the close of regular trading on the NYSE. 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, an independent pricing service. 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 dealers and other sources, as required. Credit default swaps are valued by an independent pricing service based upon valuation models incorporating default probabilities, estimated recovery rates, actual reported transactions, and other available market data. 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. Short-term fixed income securities with remaining maturities of sixty days or less generally are valued at amortized cost. Trading in foreign securities is substantially completed each day at various times prior to the close of the NYSE. The values of such securities used in computing the net asset value of the Fund's shares are determined as of such times. Securities or loan interests for which independent pricing services are unable to supply prices or for which market prices and/or quotations are not readily available or are considered to be unreliable are valued by or at the direction or with the approval of the Valuation Committee using fair value methods pursuant to procedures adopted by the Board of Trustees. The Valuation Committee is comprised of certain members of the Board of Trustees. The Fund may use fair value methods if it is determined that a significant event has occurred after the close of the exchange or market on which the security trades and prior to the determination of the Fund's net asset value. Examples of a significant event might include political or economic news, corporate restructurings, natural disasters, terrorist activity or trading halts. Thus, the valuation of the Fund's securities may differ significantly from exchange prices and such differences could be material. PIM is responsible for Pioneer Floating Rate Fund | Annual Report | 10/31/12 53 monitoring developments that may impact fair valued securities and for discussing and assessing fair values on an ongoing basis, and at least quarterly, with the Valuation Committee. At October 31, 2012, there were no securities that were valued using fair value methods (other than securities valued using prices supplied by independent pricing services). Inputs used when applying fair value methods to value a security may include credit ratings, the financial condition of the company, current market conditions and comparable securities. 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/premiums on debt securities are accreted/amortized for financial reporting purposes over the life of the respective securities, and such accretion/amortization is included in interest income. 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. Interest income, including interest on income bearing cash accounts, is recorded on the accrual basis. Dividend and interest income are reported net of unrecoverable foreign taxes withheld at the applicable country rates. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. B. 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. As of October 31, 2012, the Fund did not have any interest and penalties related to unrecognized tax positions, which, if applicable, would be recorded as an income tax expense in the Statement of Operations. Tax years for the prior three fiscal years are subject to examination by federal and state tax authorities. 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. 54 Pioneer Floating Rate Fund | Annual Report | 10/31/12 At October 31, 2012, the Fund reclassified $318,003 to decrease undistributed net investment income and $318,003 to decrease 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, 2012, the Fund was permitted to carry forward indefinitely $154,945 of long-term losses under the Regulated Investment Company Modernization Act of 2010 without limitation. Additionally, at October 31, 2012, the Fund had a net capital loss carryforward of $1,891,734 of which the following amounts will expire between 2016 and 2019 if not utilized: $349,923 in 2016, $967,278 in 2017 and $574,533 in 2019. Since new losses are required to be utilized prior to losses incurred in pre-enactment tax years, pre-enactment capital loss carryforwards may be more likely to expire unused. The tax character of distributions paid during the years ended October 31, 2012 and October 31, 2011 was as follows: ----------------------------------------------------------------------- 2012 2011 ----------------------------------------------------------------------- Distributions paid from: Ordinary income $13,587,778 $12,332,860 ----------------------------------------------------------------------- Total $13,587,778 $12,332,860 ======================================================================= The following shows the components of distributable earnings on a federal income tax basis at October 31, 2012: ------------------------------------------------------------------------- 2012 ------------------------------------------------------------------------- Distributable earnings: Undistributed ordinary income $ 981,310 Capital loss carryforward (2,046,679) Dividend payable (174,049) Net unrealized gain 1,535,816 ------------------------------------------------------------------------- Total $ 296,398 ========================================================================= The difference between book-basis and tax-basis net unrealized gain is attributable to the adjustments relating to catastrophe bonds, the tax treatment of premium and amortization, the mark-to-market of forward currency and credit default swaps, interest on defaulted bonds and interest accruals on preferred stock. C. Forward Foreign Currency Contracts The Fund may enter into forward foreign currency contracts (contracts) for the purchase or sale of a specific foreign currency at a fixed price on a future date. All contracts are marked to market daily at the applicable exchange rates, and any resulting unrealized gains or losses are recorded in the Fund's financial statements. The Fund records realized gains and losses at the time a Pioneer Floating Rate Fund | Annual Report | 10/31/12 55 portfolio hedge and settlement contract is offset by entry into a closing transaction or extinguished by delivery of the currency. Risks may arise upon entering into these contracts from the potential inability of counterparties to meet the terms of the contract and from unanticipated movements in the value of foreign currencies relative to the U.S. dollar (see Note 6). D. 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 $25,558 in underwriting commissions on the sale of Class A shares during the year ended October 31, 2012. E. 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 and Class Z 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). 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, Class Y and Class Z shares can reflect different transfer agent and distribution expense rates. F. Risks At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making the Fund more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. The Fund invests in below investment grade (high yield) debt securities. Debt securities rated below investment grade are commonly referred to as "junk bonds" and are 56 Pioneer Floating Rate Fund | Annual Report | 10/31/12 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 investments in a developed market. Risks associated with these markets include disruptive political or economic conditions and the possible imposition of adverse governmental laws or currency exchange restrictions. The Fund's prospectus contains unaudited information regarding the Fund's principal risks. Please refer to that document when considering the Fund's principal risks. G. 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. H. Credit Default Swap Agreements A credit default swap is a contract between a buyer of protection and a seller of protection against a pre-defined credit event. The Fund may buy or sell credit default swap contracts to increase the Fund's income, to add leverage to the portfolio or to hedge the risk of default on portfolio securities. As a seller of protection, the Fund would be required to pay the notional (or other agreed-upon) value of the referenced debt obligation to the counterparty in the event of a default by a U.S. or foreign corporate issuer of a debt obligation, which would likely result in a loss to the Fund. In return, the Fund would receive from the counterparty a periodic stream of payments during the term of the contract provided that no event of default occurred. The maximum exposure of loss to the seller would be the notional value of the credit default swaps outstanding. If no default occurs, the Fund would keep the stream of payments and would have no payment obligation. The Fund may also buy credit default swap contracts in order to hedge against the risk of default of debt securities, in which case the Fund would function as the counterparty referenced above. Pioneer Floating Rate Fund | Annual Report | 10/31/12 57 When the Fund enters into a credit default swap contract, one party, the protection buyer, makes an upfront or periodic payment to the protection seller in exchange for the right to receive a contingent payment. An upfront payment received by the Fund, as the protection seller, is recorded as a liability in the Fund's records. An upfront payment made by the Fund, as the protection buyer, is recorded as an asset in the Fund's records. Periodic payments received or paid by the Fund are recorded as realized gains or losses. The credit default swap contracts are marked-to-market daily using valuations supplied by independent sources and the change in value, if any, is recorded as unrealized gain or loss. Payments received or made as a result of a credit event or upon termination of the contract are recognized, net of the appropriate amount of the upfront payment, as realized gains or losses. Credit default swap contracts involving the sale of protection may involve greater risks than if the Fund had invested in the referenced debt instrument directly. Credit default swap contracts are subject to general market risk, liquidity risk, counterparty risk and credit risk. If the Fund is a protection buyer and no credit event occurs, it will lose its investment. If the Fund is a protection seller and a credit event occurs, the value of the referenced debt instrument received by the Fund, together with the periodic payments received, may be less than the amount the Fund pays to the protection buyer, resulting in a loss to the Fund. During the year ended October 31, 2012, the Fund opened one credit default swap contract, with a notional principal of $500,000, which was still open at year end. Credit default swap contracts outstanding at year end are listed at the end of the Fund's schedule of investments. 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% on assets over $500 million. For the year ended October 31, 2012, 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 0.70% and 0.90% of the Fund's average daily net assets attributable to Class Y and Class Z shares, respectively. Fees waived and expenses reimbursed during the year ended October 31, 2012, are reflected on the Statement of Operations. These expense limitations are in effect through March 1, 2014. There can be no assurance that PIM will extend the expense limitation agreement for a class of shares beyond the date referred to above. 58 Pioneer Floating Rate Fund | Annual Report | 10/31/12 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 $21,364 in management fees, administrative costs and certain other reimbursements payable to PIM at October 31, 2012. Effective March 5, 2012, PIM has retained Brown Brothers Harriman & Co. to provide certain sub-administration and accounting services to the Fund. 3. Transfer Agent PIMSS, a wholly owned indirect subsidiary of UniCredit, provides substantially all transfer agent and shareowner services to the Fund at negotiated rates. In addition, the Fund reimburses PIMSS for out-of-pocket expenses incurred by PIMSS related to shareholder communications activities such as proxy and statement mailings, outgoing phone calls and omnibus relationship contracts. For the year ended October 31, 2012, such out-of-pocket expenses by class of shares were as follows: -------------------------------------------------------------------------------- Shareholder Communications: -------------------------------------------------------------------------------- Class A $100,490 Class C 34,131 Class Y 47,362 Class Z 124 -------------------------------------------------------------------------------- Total $182,107 ================================================================================ Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $60,695 in transfer agent fees and out-of-pocket reimbursements payable to PIMSS at October 31, 2012. 4. Distribution Plan The Fund has adopted a Distribution Plan pursuant to Rule 12b-1 of the Investment Company Act of 1940 with respect to its Class A 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 Pioneer Floating Rate Fund | Annual Report | 10/31/12 59 distribution services with regard to Class C shares. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $6,295 in distribution fees payable to PFD at October 31, 2012. In addition, redemptions of each class of shares (except Class Y and Z shares) may be subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may be imposed on redemptions of certain net asset value purchases of Class A shares within 12 months of purchase. 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 or Z shares. Proceeds from the CDSC are paid to PFD. For the year ended October 31, 2012, CDSCs in the amount of $43,942 were paid to PFD. 5. Expense Offset Arrangements The Fund has entered into certain expense offset arrangements with PIMSS which may result in a reduction in the Fund's total expenses due to interest earned on cash held by PIMSS. For the year ended October 31, 2012, the Fund's expenses were not reduced under such arrangements. 6. Forward Foreign Currency Contracts At October 31, 2012, the Fund had entered into various forward foreign currency contracts that obligate the Fund to deliver or take delivery of currencies at specified future maturity dates. Alternatively, prior to the settlement date of a forward foreign currency contract, the Fund may close out such contract by entering into an offsetting contract. The average number of contracts open during the year ended October 31, 2012 was 3,901,730. At October 31, 2012, the Fund had no outstanding settlement contracts. Open portfolio hedges at October 31, 2012 were as follows: ------------------------------------------------------------------------------------ Net In Net Contracts Exchange Settlement Unrealized Currency to Deliver For USD Date Value Gain (Loss) ------------------------------------------------------------------------------------ EUR (Euro) (915,000) $(1,183,778) 11/14/12 $(1,186,289) $ (2,511) NOK (Norwegian Krone) (1,433,000) (234,903) 12/17/12 (250,961) (16,058) ------------------------------------------------------------------------------------ Total $(18,569) ==================================================================================== 60 Pioneer Floating Rate Fund | Annual Report | 10/31/12 7. Line of Credit Facility The Fund, along with certain other funds in the Pioneer Family of Funds (the Funds), participates in a committed, unsecured revolving line of credit facility. Borrowings are used solely for temporary or emergency purposes. The Fund may borrow up to the lesser of the amount available under the facility or the limits set for borrowing by the Fund's prospectus and the 1940 Act. The credit facility in effect until January 20, 2012 was in the amount of $165 million. Under such facility, interest on borrowings was payable at the higher of the London Interbank Offered Rate (LIBOR) on the borrowing date plus 1.25% on an annualized basis or the Federal Funds Rate on the borrowing date plus 1.25% on an annualized basis. The credit facility in effect as of February 15, 2012 is in the amount of $215 million. Under such facility, depending on the type of loan, interest on borrowings is payable at LIBOR plus 0.90% on an annualized basis, or the Alternate Base Rate, which is the greater of (a) the facility's administrative agent's daily announced prime rate on the borrowing date, (b) 2% plus the Federal Funds Rate on the borrowing date and (c) 2% plus the overnight Euro dollar rate on the borrowing date. The Funds pay an annual commitment fee to participate in a credit facility.

These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Fund's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of October 31, 2012, 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 provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Pioneer Floating Rate Fund at October 31, 2012, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, 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 28, 2012 Pioneer Floating Rate Fund | Annual Report | 10/31/12 63 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.
