Employment has also been rising steadily, but only modestly. Consumer incomes, savings, wealth, and debt-servicing capacity have been solid buttresses for the recovering housing and auto industries. Industrial activity is growing only modestly, but current corporate profits are generally solid and balance sheets appear able to support needed capital spending and dividend* payouts. The scaled-back "fiscal cliff" tax increases and spending cuts have meaningfully cut the budget deficit without driving the economy into recession. In addition, we feel that continuing slack in labor markets and capacity utilization offers the potential for continuing growth without bottlenecks and rising inflation. After observing the strengthening economic trends, the Federal Reserve (the Fed) hinted that it might begin scaling back its "QE" quantitative easing program later in 2013 and could terminate its bond purchases altogether sometime in 2014. In September, however, the Fed surprised many market participants by deciding not to start scaling back QE yet. The Fed has also said that short-term interest rates are likely to remain near zero for some time to come, given that inflation remains subdued and unemployment remains too high. As September ended, Congress had not yet passed a continuing resolution to prevent a government shutdown, nor had it raised the debt ceiling, and a quick resolution to the impasse appeared unlikely. The U.S. government's partial shutdown in October rattled the markets to a degree, but did not immediately have a significant negative impact on the economy or capital markets. There are certainly risks and uncertainties that continue to plague the global economy as we head into the final months of the year. The European economy remains weak, though it is beginning to show signs of stabilization, and a number of countries in the emerging markets have experienced difficulties. Still, a potential ending of the European recession, continuing economic improvement in Japan in response to the new government's easing policies, and a "soft landing" of 7% growth in China could very well result in an improving global outlook over the remainder of 2013 and in 2014. There are also geopolitical worries abroad and the aforementioned political fights at home, and while most of the widely recognized risks we've outlined may already be "priced into" the market, we believe investors should continue to expect market volatility. * Dividends are not guaranteed. 2 Pioneer Floating Rate Fund | Annual Report | 10/31/13 The Fed's aggressive monetary policies and fears about economic growth had helped drive long-term Treasury yields to unsustainably low levels; the return to more normal levels has resulted in disappointing returns for bond investors during the first nine months of 2013, but the stock market has delivered double-digit returns to equity investors who were willing to brave the "wall of worry". At Pioneer, we have long advocated the benefits of staying diversified and investing for the long term. And while diversification does not assure a profit or protect against loss in a declining market, we believe there are still opportunities for prudent investors to earn attractive returns. 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, keeping in mind that there is no single best strategy that works for every investor. Pioneer's investment teams have, since 1928, sought out attractive opportunities in global equity and bond markets, using in-depth research in an effort to identify undervalued individual securities, and using thoughtful risk management to construct portfolios which seek to balance potential risks and reward in an ever-changing world. We encourage 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. We greatly appreciate your trust in us, and we thank you for investing with Pioneer. Sincerely, /s/ Daniel K. Kingsbury Daniel K. Kingsbury President and CEO Pioneer Investment Management USA, Inc.

Pioneer Floating Rate Fund | Annual Report | 10/31/13 3 Portfolio Management Discussion | 10/31/13 Floating-rate bank loans generally outperformed many other fixed-income investments during the 12-month period ended October 31, 2013. The floating interest rates of bank loans helped them to better withstand pressures of rising interest rates and declining bond prices that occurred during the second half of the period. In the following interview, Jonathan Sharkey discusses the factors that influenced the performance of Pioneer Floating Rate Fund during the 12-month period. Mr. Sharkey, a senior vice president and portfolio manager at Pioneer, is responsible for the day-to-day management of the Fund. Q How would you describe the investment environment for bank loans during the 12-month period ended October 31, 2013? A The market environment was supportive for healthy returns for credit- sensitive investments during the first half of the Fund's fiscal year ended October 31, 2013. Demand was especially strong for floating-rate bank loans as yield-seeking investors looked for alternatives at a time when many fixed-income investments offered comparatively little current income potential. Financial institutions issued new pooled investment vehicles known as collateralized loan obligations (CLOs) that invested in bank loans, while high-yield portfolio managers also saw good opportunities in bank loans. The market environment began changing, however, in May of 2013 after Federal Reserve (Fed) Chairman Ben Bernanke suggested that if the American economy continued to improve, the U.S. central bank might begin tapering back its more aggressive monetary policies, such as quantitative easing (QE), that had contributed to liquidity in the markets. Mr. Bernanke's comments set off speculation that interest rates would soon begin to rise. In fact, market interest rates did begin rising sharply during the summer of 2013, even though existing Fed monetary policies remained in effect. U.S. Treasuries, in particular, performed poorly, but fixed-rate credit-sensitive securities also were affected by the spike in rates. Bank loans, because of their feature providing for increasing yields as market interest rates rise, attracted more investors and tended to outperform many fixed-income alternatives. More investment money flowed into the bank-loan market during June, July, and August, contributing significantly to the outperformance of the asset class. Performance of bank loans was not always positive throughout the entire 12-month period, though, as in June 2013 high-yield investors sold off some of their bank-loan investments because they were more liquid and easily tradable than fixed-rate bonds. The net flows into bank loans eased 4 Pioneer Floating Rate Fund | Annual Report | 10/31/13 during the final two months of the period (September and October), as the Fed ultimately decided against tapering QE and opted for a status quo monetary policy, at least for the time being. Fixed-rate investments then began re-attracting some investor assets from floating-rate securities, although bank loans continued to produce positive returns on an absolute basis. Q How did the Fund perform in that environment during the 12-month period ended October 31, 2013? A Pioneer Floating Rate Fund's Class A shares returned 4.24% at net asset value during the 12-month period ended October 31, 2013, while the Fund's benchmark, the Barclays High Yield Loans Performing Index (the Barclays Index), returned 5.42%. During the same period, the average return of the 167 mutual funds in Lipper's Loan Participating Funds category was 5.56%, and the average return of the 206 mutual funds in Morningstar's Bank Loan Funds category was 5.82%. Q How did you position the Fund's portfolio during the 12-month period ended October 31, 2013, and how did that positioning affect benchmark-relative performance? A Throughout the period, we maintained an up-in-quality focus when investing the Fund's portfolio in floating-rate loans. The emphasis tended to hold back results relative to the benchmark Barclays Index early in the period when demand was strong for all credit-sensitive debt securities and lower-rated investments tended to outperform. However, the Fund's benchmark-relative results improved later in the period as the market became more unsettled and the Fund tended to perform largely in line with the overall floating-rate market. The portfolio did hold a small position in some fixed-rate debt for liquidity purposes, and that exposure dragged on the Fund's benchmark-relative performance later in the period when fixed-rate securities underperformed. We continue to believe that our emphasis on securities rated "B" and higher is preferable over the longer term, even though it sometimes may result in benchmark-relative underperformance when lower-rated debt outperforms. At the end of the Fund's fiscal year on October 31, 2013, the Fund had only minimal exposure (less than 1% of net assets) to loans rated CCC and below, even though those securities had outperformed early in the 12-month period. The greatest concentrations of assets in the portfolio as of period end were in BB-rated loans (nearly 46% of net assets) and in B-rated loans (just below 40% of net assets). Pioneer Floating Rate Fund | Annual Report | 10/31/13 5 Q Which individual investments had the biggest effect on the Fund's performance during the 12-month period ended October 31, 2013? A The financial restructuring of global mining corporation Bumi Resources - after the company had defaulted on some debt - resulted in a strong recovery in the value of the Fund's investment in Bumi's loans. Another portfolio holding that contributed to the Fund's performance during the period was a loan to Newhall Land and Farming, a California-based development firm that performed very well as the housing market rebounded. Loans to FTS International, an energy services company, also fared well and helped to support the Fund's results during the period. Several portfolio investments detracted from the Fund's relative results during the 12-month period. The underperforming holdings included: loans to Accent Care, a home health care service provider that was affected by reductions in government reimbursements; to Preferred Proppants, a distributor of materials used in natural gas drilling operations whose performance was affected when higher relative prices for oil led to an increase in oil drilling at the expense of gas drilling; and to Cengage Learning, a publisher of college textbooks that encountered declining demand for textbooks as Internet-based learning opportunities increased. Q What is your investment outlook? A We think the fixed-income market, including the market for bank loan-based securities, should stabilize in the coming months. The major political fights in Washington, D.C., over issues such as the debt ceiling, government spending and taxation appear to have been resolved, at least temporarily. In that environment, we believe that domestic economic growth should continue to strengthen, if only moderately, and that loan deals should increase as corporate activities such as leveraged buyouts and mergers and acquisitions increase in number. The default rates for bank loans remain well below historical averages, reflecting the overall good quality of outstanding debt, and that should encourage further flows of investor assets into the bank-loan market. The main advantage to investors in bank loans - their floating rates - should prove especially compelling as the likelihood grows that market interest rates at some point will begin rising again. We believe that advantage will become even more obvious when the Fed eventually begins to withdraw some of its more aggressive monetary support from the economy. 6 Pioneer Floating Rate Fund | Annual Report | 10/31/13 Please refer to the Schedule of Investments on pages 16-55 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. Investing in foreign and/or emerging markets securities involves risks relating to interest rates, currency exchange rates, economic, and political conditions. 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.

Pioneer Floating Rate Fund | Annual Report | 10/31/13 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, 2013, through October 31, 2013. -------------------------------------------------------------------------------- Share Class A C Y Z -------------------------------------------------------------------------------- Beginning Account $1,000.00 $1,000.00 $1,000.00 $1,000.00 Value on 5/1/13 -------------------------------------------------------------------------------- Ending Account $1,010.57 $1,006.80 $1,012.47 $1,011.52 Value (after expenses) on 10/31/13 -------------------------------------------------------------------------------- Expenses Paid $ 5.37 $ 9.10 $ 3.55 $ 4.56 During Period* -------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio of 1.06%, 1.80%, 0.70% and 0.90% for Class A, Class C, Class Y and Class Z shares, respectively, multiplied by the average account value over the period, multiplied by 184/365 (to reflect the partial year period). 14 Pioneer Floating Rate Fund | Annual Report | 10/31/13 Hypothetical Example for Comparison Purposes The table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads) that are charged at the time of the transaction. Therefore, the table below is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher.

Pioneer Floating Rate Fund | Annual Report | 10/31/13 63 Notes to Financial Statements | 10/31/13 1. 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: 64 Pioneer Floating Rate Fund | Annual Report | 10/31/13 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. If price information is not available from Loan Pricing Corporation, or if the price information is deemed to be unreliable, price information will be obtained from an alternative loan interest pricing service. If no reliable price quotes are available from either the primary or alternative pricing service, broker quotes will be solicited. 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 senior 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 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. 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. 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 Pioneer Floating Rate Fund | Annual Report | 10/31/13 65 securities may differ significantly from exchange prices and such differences could be material. Pioneer Investment Management, Inc. (PIM), the fund's investment adviser, 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. At October 31, 2013, there were no securities that were valued using fair value methods (other than securities valued using prices supplied by independent pricing services). 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, 2013, the Fund did not accrue any interest and penalties with respect to uncertain tax positions, which, if applicable, would be recorded as an income tax expense in the Statement of Operations. Tax returns filed within the prior three years remain subject to examination by federal and state tax authorities. The amount and character of income and capital gain distributions to shareowners are determined in accordance with federal income tax rules, which may differ from U.S. generally accepted accounting principles. Distributions in excess of net investment income or net realized gains are temporary overdistributions for financial statement purposes resulting from differences in the recognition or classification of income or distributions for financial statement and tax purposes. Capital accounts within the financial statements are adjusted for permanent book/tax differences to reflect tax 66 Pioneer Floating Rate Fund | Annual Report | 10/31/13 character, but are not adjusted for temporary differences. At October 31, 2013, the Fund reclassified $686,787 to decrease undistributed net investment income and $686,787 to decrease accumulated net realized loss on investments to reflect permanent book/tax differences. These adjustments have no impact on net assets or the results of operations. At October 31, 2013, the Fund was permitted to carry forward indefinitely $304,738 of long-term losses under the Regulated Investment Company Modernization Act of 2010 without limitation. Additionally, at October 31, 2013, the Fund had a net capital loss carryforward of $1,891,734 of which the following amounts will expire in 2016, 2017 and 2019 if not utilized: $349,923 in 2016, $967,278 in 2017 and $574,533 in 2019. The tax character of distributions paid during the years ended October 31, 2013 and October 31, 2012 was as follows: ---------------------------------------------------------------------------- 2013 2012 ---------------------------------------------------------------------------- Distributions paid from: Ordinary income $22,153,748 $13,587,778 ---------------------------------------------------------------------------- Total $22,153,748 $13,587,778 ============================================================================ The following shows the components of distributable earnings on a federal income tax basis at October 31, 2013: ---------------------------------------------------------------------------- 2013 ---------------------------------------------------------------------------- Distributable earnings: Undistributed ordinary income $ 2,236,313 Capital loss carryforward (2,196,472) Dividend payable (2,176,160) Net unrealized appreciation 1,981,070 ---------------------------------------------------------------------------- Total $ (155,249) ============================================================================ The difference between book basis and tax basis unrealized appreciation is attributable to the tax deferral of losses on wash sales, adjustments relating to catastrophe bonds, the tax treatment of premium and amortization, the mark to market of forward foreign currency and futures contracts, tax basis adjustments on Real Estate Investment Trust (REIT) holdings, interest accruals on preferred stock, partnerships and other holdings. 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 appreciation or depreciation is recorded in the Fund's financial statements. The Fund records realized gains and losses at the time a contract is offset by entry into a closing transaction or extinguished by delivery of the currency. Risks may arise upon entering into these contracts Pioneer Floating Rate Fund | Annual Report | 10/31/13 67 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 $58,577 in underwriting commissions on the sale of Class A shares during the year ended October 31, 2013. 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 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 68 Pioneer Floating Rate Fund | Annual Report | 10/31/13 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. 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 seek to increase the Fund's income or to attempt 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. When the Fund enters into a credit default swap contract, either the buyer or seller of protection will make a rebalancing payment to the other party. The amount of the rebalancing payment is determined based on the value of the contract on the trade date. 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 Pioneer Floating Rate Fund | Annual Report | 10/31/13 69 unrealized appreciation or depreciation. 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. In addition, obligations under sell protection credit default swaps may be partially offset by net amounts received from settlement of buy protection credit default swaps entered into by the Fund for the same reference obligation with the same counterparty. As the seller of protection, the Fund held one credit default swap contract with a notional amount of $2,750,000 at October 31, 2013. When the Fund entered into the credit default swap contract, the Fund received a rebalancing payment from the buyer of protection in the amount of $146,953, which is recorded as credit default swap premiums received on the Statement of Assets and Liabilities. If a defined credit event had occurred at October 31, 2013, the maximum amount the Fund would have been required to pay was $2,959,805. This amount includes net unrealized appreciation of $78,893, as reflected in the Schedule of Investments. The Fund did not have any open purchase contracts as of October 31, 2013. The average value of swap contracts open during the year ended October 31, 2013 was $760,021. 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, 2013, the annualized management fee (excluding waivers and/or assumption of expenses) was equivalent to 0.59% 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, 2013, 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. 70 Pioneer Floating Rate Fund | Annual Report | 10/31/13 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 $166,801 in management fees, administrative costs and certain other reimbursements payable to PIM at October 31, 2013. 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, 2013, such out-of-pocket expenses by class of shares were as follows: -------------------------------------------------------------------------------- Shareholder Communications: -------------------------------------------------------------------------------- Class A $194,632 Class C 71,335 Class Y 205,377 Class Z 18,862 -------------------------------------------------------------------------------- Total $490,206 ================================================================================ Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $107,477 in transfer agent fees and out-of-pocket reimbursements payable to PIMSS at October 31, 2013. 4. Distribution Plan The Fund has adopted a Distribution Plan pursuant to Rule 12b-1 of the Investment Company Act of 1940 with respect to its Class A and Class C shares. Pursuant to the Plan, the Fund pays PFD 0.25% of the average daily net assets attributable to Class A shares as compensation for personal services and/or account maintenance services or distribution services with regard to Class A shares. Pursuant to the Plan, the Fund also pays PFD 1.00% of the average daily net assets attributable to Class C shares. The fee for Class C shares consists of a 0.25% service fee and a 0.75% distribution fee paid as compensation for personal services and/or account maintenance services or distribution services with regard to Class C shares. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $10,719 in distribution fees payable to PFD at October 31, 2013. Pioneer Floating Rate Fund | Annual Report | 10/31/13 71 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 12 months 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 originalpurchase 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, 2013, CDSCs in the amount of $44,388 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, 2013, the Fund's expenses were not reduced under such arrangements. 6. Forward Foreign Currency Contracts At October 31, 2013, 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 value of contracts open during the year ended October 31, 2013 was $704,388. As of October 31, 2013, outstanding forward foreign currency contracts were as follows: -------------------------------------------------------------------------------- Net In Net Contracts Exchange Settlement Unrealized Currency to Deliver For USD Date Value Depreciation -------------------------------------------------------------------------------- EUR (Euro) (250,000) $330,635 11/6/13 $ (339,715) $ (9,080) -------------------------------------------------------------------------------- Total $ (9,080) ================================================================================ 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 is in the amount of $215 million. Under such facility, depending on the type of loan, interest on borrowings is payable at the London Interbank Offered Rate (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 72 Pioneer Floating Rate Fund | Annual Report | 10/31/13 date and (c) 2% plus the overnight Euro dollar rate on the borrowing date. The Funds pay an annual commitment fee to participate in the 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, 2013, the Fund had no borrowings under the credit facility. 8.

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, 2013 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 (one of the portfolios constituting Pioneer Series Trust VI) at October 31, 2013, 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, and the financial highlights for each of the periods indicated therein, in conformity with U.S. generally accepted accounting principles. /s/ Ernst & Young LLP Boston, Massachusetts December 23, 2013 74 Pioneer Floating Rate Fund | Annual Report | 10/31/13 Trustees, Officers and Service Providers Investment Adviser Pioneer Investment Management, Inc.

Employment has also been rising steadily, but only modestly. Consumer incomes, savings, wealth, and debt-servicing capacity have been solid buttresses for the recovering housing and auto industries. Industrial activity is growing only modestly, but current corporate profits are generally solid and balance sheets appear able to support needed capital spending and dividend* payouts. The scaled-back "fiscal cliff" tax increases and spending cuts have meaningfully cut the budget deficit without driving the economy into recession. In addition, we feel that continuing slack in labor markets and capacity utilization offers the potential for continuing growth without bottlenecks and rising inflation. After observing the strengthening economic trends, the Federal Reserve (the Fed) hinted that it might begin scaling back its "QE" quantitative easing program later in 2013 and could terminate its bond purchases altogether sometime in 2014. In September, however, the Fed surprised many market participants by deciding not to start scaling back QE yet. The Fed has also said that short-term interest rates are likely to remain near zero for some time to come, given that inflation remains subdued and unemployment remains too high. As September ended, Congress had not yet passed a continuing resolution to prevent a government shutdown, nor had it raised the debt ceiling, and a quick resolution to the impasse appeared unlikely. The U.S. government's partial shutdown in October rattled the markets to a degree, but did not immediately have a significant negative impact on the economy or capital markets. There are certainly risks and uncertainties that continue to plague the global economy as we head into the final months of the year. The European economy remains weak, though it is beginning to show signs of stabilization, and a number of countries in the emerging markets have experienced difficulties. Still, a potential ending of the European recession, continuing economic improvement in Japan in response to the new government's easing policies, and a "soft landing" of 7% growth in China could very well result in an improving global outlook over the remainder of 2013 and in 2014. There are also geopolitical worries abroad and the aforementioned political fights at home, and while most of the widely recognized risks we've outlined may already be "priced into" the market, we believe investors should continue to expect market volatility. * Dividends are not guaranteed. 2 Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/13 The Fed's aggressive monetary policies and fears about economic growth had helped drive long-term Treasury yields to unsustainably low levels; the return to more normal levels has resulted in disappointing returns for bond investors during the first nine months of 2013, but the stock market has delivered double-digit returns to equity investors who were willing to brave the "wall of worry". At Pioneer, we have long advocated the benefits of staying diversified and investing for the long term. And while diversification does not assure a profit or protect against loss in a declining market, we believe there are still opportunities for prudent investors to earn attractive returns. 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, keeping in mind that there is no single best strategy that works for every investor. Pioneer's investment teams have, since 1928, sought out attractive opportunities in global equity and bond markets, using in-depth research in an effort to identify undervalued individual securities, and using thoughtful risk management to construct portfolios which seek to balance potential risks and reward in an ever-changing world. We encourage 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. We greatly appreciate your trust in us, and we thank you for investing with Pioneer. Sincerely, /s/ Daniel K. Kingsbury Daniel K. Kingsbury President and CEO Pioneer Investment Management USA, Inc.

Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/13 3 Portfolio Management Discussion | 10/31/13 In the following discussion, Michele Garau reviews recent market events and describes the factors that affected the performance of Pioneer Multi-Asset Real Return Fund during the 12-month period ended October 31, 2013.Mr. Garau, a senior vice president and portfolio manager at Pioneer, is responsible for the day-to-day management of the Fund along with associate portfolio manager Howard Weiss. Q How did the Fund perform during the 12-month period ended October 31, 2013? A Pioneer Multi-Asset Real Return Fund's Class A shares returned 14.72% at net asset value during the 12-month period ended October 31, 2013, while the Fund's benchmark, the Barclays U.S. Treasury TIPS 1-10 Year Index (the Barclays Index), returned -3.78%. During the same period, the average return of the 425 mutual funds in Lipper's Global Flexible Portfolio Funds category was 10.21%, and the average return of the 236 mutual funds in Morningstar's Tactical Allocation Funds category was 8.44%. Q Could you please review the Fund's overall investment approach? A The Fund seeks to generate real returns--or, in other words, a return in excess of inflation--across a full range of economic scenarios through a multi-asset, diversified*, flexible approach that allocates among traditional financial assets, such as stocks and bonds, and real assets. In choosing investments for the Fund, we seek those that we believe can provide the best return profile for the least amount of risk and incremental cost. We believe our opportunistic investment philosophy provides us with a greater degree of latitude to seek positive real returns for the Fund over time, no matter what the level of inflation. Q How was the Fund positioned as of October 31, 2013? A We continued to tilt the portfolio's investments towards global equities, as we believed them to be the most attractively valued asset class in an environment over the past year that was characterized by gradually improving economic growth and high corporate profit margins. As of October 31, 2013, more than 74% of the Fund's portfolio was invested in equities, both U.S. and international, while 20% was invested in fixed-income investments and 5% was held in investments, such as exchange-traded funds (ETFs), that gave the portfolio exposure to real assets (real estate investment trusts, oil, platinum, lumber, etc.). The remainder was held in cash. * Diversification does not assure a profit nor protect against loss in a declining market. 4 Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/13 The Fund's substantial weighting in equities during the period was consistent with our positioning since we began managing the Fund more than three years ago. We believe this helps to illustrate the long-term nature of our investment approach, as we tend not to shift the portfolio's positioning on the basis of short-term news flows; instead, we develop a thesis based on our five-to six-year outlook and we stick by it during periods of volatility. The approach has served us well, as evidenced by the Fund's strong absolute and relative performance during the 12-month period. Q What types of stocks or equity-linked investments did you see as providing the best opportunities during the 12-month period ended October 31, 2013? A We maintained a "barbell" approach of owning dividend-paying**, global large-caps in the portfolio on the one hand, and emerging markets equities on the other. High-quality, dividend-paying stocks make up the core of the Fund's portfolio. We are focused on identifying stocks that offer not just a decent current dividend, but also a strong chance of future dividend growth. We believe dividend growth is an essential component of a strategy that seeks to help investors maintain their long-term purchasing power, since - unlike with bond investments - there is the opportunity for income to increase over time. This approach naturally leads us to invest the portfolio in the types of conservative companies that populate the consumer staples, financials, and industrials sectors. While that positioning held back the Fund's performance to a small degree during the "risk-on" environment of the past 12 months, we believe it represents the most prudent long-term investment strategy. We have maintained a large portfolio exposure to the emerging markets, since those markets provide both non-U.S. dollar exposure and a way to participate in the strength of overseas economic growth. We continue to favor Asian stocks in the portfolio, with an emphasis on Korea, Thailand, Philippines, Indonesia, and Malaysia, along with a new allocation to China that we added during the third calendar quarter of 2013. The basis for that element of the Fund's positioning is our belief that the balance of global economic power is gradually swinging towards Asia. While this trend may have been lost amid more recent concerns about a "hard landing" for China's economy, we believe the longer-term shift remains inexorable. In addition, Asia remains home to a high proportion of companies with very attractive fundamentals, compelling valuations, and governments with healthy finances and positive trade balances. ** Dividends are not guaranteed. Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/13 5 The Fund's largest individual position as of October 31, 2013, is in the PowerShares Buyback Achievers ETF, which invests in U.S.-listed stocks that have repurchased at least 5% or more of their shares outstanding during the trailing 12-month period. We initiated the position in March of 2012 on the belief that the capital discipline imposed by share buybacks forces company managements to pursue activities with the highest probabilities of producing positive returns on investment. The ETF has performed very well for the Fund since our initial purchase, outperforming the broader U.S. market. Q Please discuss the Fund's positioning in the global bond markets as of October 31, 2013. A We view the bond market, as a whole, as being expensive. Yields are still too low despite the downturn that occurred during May and June when the U.S. Federal Reserve Board (the Fed) hinted at a possible tapering of its quantitative easing (QE) program, which led to a temporary spike in market interest rates. In our view, that makes the asset class vulnerable to additional downdrafts in the coming years. With that said, we believe there are certain areas of the market that offer attractive relative values. We are finding some of the most compelling opportunities in corporate bonds issued by companies in the developed international and emerging markets, where issuer credit quality is high and investors are being appropriately compensated for the risks they assume. In addition, the Fund has a modest allocation to U.S. corporate bonds. We continue to avoid U.S. government bonds and most other sovereign-debt instruments, with the notable exceptions of Ireland, Mexico, and Romania. Across all segments of the Fund's bond portfolio, we have favored shorter-term issues in order to minimize the potential impact of rising rates. Q How is the Fund positioned in commodity-linked investments as of October 31, 2013? A The portfolio's allocation remains fairly limited, as it has for more than a year. There are three reasons for the modest weighting. First, commodities have been exhibiting a very high correlation to equities in recent years, limiting the diversification they provide. Second, we see better opportunities - particularly on a risk-adjusted basis - in equities. And third, China is not as big a buyer of commodities today as it was two to three years ago, as the Chinese government has taken steps to rein in growth. Given that background, our approach has been to take advantage of select opportunities in specific commodities, such as platinum, palladium, lumber, and gold, rather than establishing a broad-based portfolio allocation to the asset class. 6 Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/13 We do, however, see the opportunity for real returns in real estate investment trusts (REITs) based in Singapore. We believe the REIT securities offer safe yields and the potential for currency appreciation, which makes them a more attractive proposition than bonds in our view. Q The Fund typically holds a portion of its assets in derivative investments (options and futures). Why do you invest the Fund in these instruments? A Our goal in using derivatives isn't to add to the Fund's total return. In other words, the positions do not represent high-risk "bets" on certain market segments. Instead, we use derivatives to maintain balance in the portfolio and to attempt to "hedge" (or mitigate) the risks of certain other positions. For instance, the Fund holds a number of hedges in global currencies, which helps to reduce the impact of currency movements on specific holdings within the portfolio. Q Do you have any closing thoughts for investors? A We continue to employ a flexible, diversified, and go-anywhere approach that enables the Fund to adapt to changing market conditions by investing in any asset class or region. Rather than being constrained by a "style box" or an index, we have the ability to actively target the areas of the financial markets that we believe offer the most attractive long-term opportunities and that are best suited to our goal of helping investors maintain the long-term purchasing power of their assets. We believe the potential value of our investment approach is illustrated by the fact that the Fund has not just outperformed its benchmark and peers over the past year, but that it has done so with a lower degree of volatility. We expect that our steady, long-term approach will prove well suited to the coming year, during which time shifting economic data and talk of the Fed tapering QE is likely to lead to elevated short-term "noise" in the financial markets. Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/13 7 Please refer to the Schedule of Investments on pages 19-39 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. 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. 8 Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/13 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. High-yield bonds possess greater price volatility, illiquidity, and possibility of default. These risks may increase share price volatility. There is no assurance that these and other strategies used by the Fund or underlying funds will be successful. Please see the prospectus for a more complete discussion of the Fund's risks. 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. These statements should not be relied upon for any other purposes.

Performance shown for periods prior to the inception of Class Z shares on April 26, 2013, is the net asset value 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 April 26, 2013, would have been higher than that shown. For the period beginning April 26, 2013, the actual performance of Class Z shares is reflected. Class Z shares are not subject to sales charges and are available for limited groups of eligible investors, including institutional investors.

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 Multi-Asset Real Return Fund Based on actual returns from May 1, 2013, through October 31, 2013. --------------------------------------------------------------------------------- Share Class A C R Y Z --------------------------------------------------------------------------------- Beginning Account $1,000.00 $1,000.00 $1,000.00 $1,000.00 $1,000.00 Value on 5/1/13 --------------------------------------------------------------------------------- Ending Account $1,004.20 $1,000.44 $1,047.60 $1,004.98 $ 907.77 Value (after expenses) On 10/31/13 --------------------------------------------------------------------------------- Expenses Paid $ 6.16 $ 10.08 $ 1.62 $ 4.65 $ 5.15 During Period* --------------------------------------------------------------------------------- * Expenses are equal to the Fund's annualized expense ratio plus the expense ratio of the underlying funds. These combined totals were of 1.28%, 2.05%, 1.42%, 0.98%, and 1.18% for Class A, Class C, Class R, Class Y and Class Z shares, respectively. These combined ratios were multiplied by the average account value over the period, and then multiplied by 184/365 (49/365 for Class R shares)(to reflect the partial year period). Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/13 17 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.

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 five classes of shares designated as Class A, Class C, Class R, Class Y and Class Z shares. Class A, Class C and Class Y shares were first publicly offered on May 3, 2010. Class Z shares were first publicly offered on April 26, 2013. Class R shares were first publicly offered on September 13, 2013. 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 and 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: Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/13 49 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 an independent pricing service. If price information is not available from Loan Pricing Corporation, or if the price information is deemed to be unreliable, price information will be obtained from an alternative loan interest pricing service. If no reliable price quotes are available from either the primary or alternative pricing service, broker quotes will be solicited. 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 such funds' 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. 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. 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 50 Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/13 securities may differ significantly from exchange prices and such differences could be material. Pioneer Investment Management, Inc. (PIM), the Fund's investment adviser, 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. At October 31, 2013, no securities were valued using fair value methods (other than securities valued using prices supplied by independent pricing services). 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 the market prices of those securities but are included with the net realized and unrealized gain or loss on investments. C. Futures Contracts The Fund may enter into futures transactions in order to attempt 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 Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/13 51 to deposit with a broker an amount of cash or securities equal to the minimum "initial margin" requirements of the associated futures exchange. The amount of cash deposited with the broker as collateral at October 31, 2013 was $8,061,191. 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. 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 value of contracts open during the year ended October 31, 2013 was $262,607,079. At October 31, 2013, open futures contracts were as follows: -------------------------------------------------------------------------------------- Number of Unrealized Contracts Settlement Appreciation/ Type Long/(Short) Month Value (Depreciation) -------------------------------------------------------------------------------------- STOXX Europe 600 1,350 12/13 $ 29,467,916 $ 196,203 FTSE 100 IDX 100 12/13 10,766,472 464,273 F/C Dollar Index 260 12/13 20,868,380 104,832 SPI 200 Futures (165) 12/13 (21,132,346) (742,125) S&P 500 EMINI Futures (17) 12/13 (1,488,350) (81,621) Mexican Peso Currency Futures (105) 12/13 (4,021,500) (63,000) Crude Palm Oil Futures 1,204 1/14 24,726,533 776,834 Lumber Futures 60 11/13 2,385,900 142,372 EURO STOXX Bank (3,680) 12/13 (34,853,959) (389,164) -------------------------------------------------------------------------------------- $ 408,604 ====================================================================================== 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 appreciation or depreciation is recorded in the Fund's financial statements. The Fund records realized gains and losses at the time a 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). 52 Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/13 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, 2013, the Fund did not accrue any interest and penalties with respect to unrecognized tax positions, which, if applicable, would be recorded as an income tax expense in the Statement of Operations. Tax returns filed within the prior three years remain subject to examination by federal and state tax authorities. The amount and character of income and capital gain distributions to shareowners are determined in accordance with federal income tax rules, which may differ from U.S. generally accepted accounting principles. Distributions in excess of net investment income or net realized gains are temporary overdistributions for financial statement purposes resulting from differences in the recognition or classification of income or distributions for financial statement and tax purposes. Capital accounts within the financial statements are adjusted for permanent book/tax differences to reflect tax character, but are not adjusted for temporary differences. At October 31, 2013, the Fund reclassified $1,999,250 to decrease accumulated net investment income, $3,947,258 to increase accumulated net realized loss on investments, futures contracts, credit default swaps and foreign currency transactions and $1,948,008 to decrease paid-in capital to reflect permanent book/tax differences. These adjustments have no impact on net assets or the results of operations. During the year ended October 31, 2013, a capital loss carryforward of $4,797,476 was utilized to offset net realized gains by the Fund. The tax character of distributions paid during the years ended October 31, 2013 and October 31, 2012 were as follows: -------------------------------------------------------------------------------- 2013 2012 -------------------------------------------------------------------------------- Distributions paid from: Ordinary income $ 9,128,296 $ 10,476,948 -------------------------------------------------------------------------------- Total $ 9,128,296 $ 10,476,948 ================================================================================ The following shows the components of distributable earnings on a federal income tax basis at October 31, 2013: -------------------------------------------------------------------------------- 2013 -------------------------------------------------------------------------------- Distributable earnings: Undistributed ordinary income $ 1,485,653 Undistributed long-term gain 34,971,284 Net unrealized appreciation 73,167,685 -------------------------------------------------------------------------------- Total $ 109,624,622 ================================================================================ Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/13 53 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 foreign currency contracts 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 $139,663 in underwriting commissions on the sale of Class A shares during the year ended October 31, 2013. 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 and Class R 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). 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 R, Class Y and Class Z shares can reflect different transfer agent and distribution expense rates. 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. 54 Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/13 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. 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. PIM is responsible for determining that the value of the collateral remains at least equal to the repurchase price. J. Option Writing The Fund may write put and covered call options on portfolio securities in order to attempt to hedge against changes in the value of portfolio securities or to seek to increase total return. When an option is written, the Fund receives a premium and becomes obligated to purchase or sell the underlying security at a fixed price, upon the exercise of the option. When the Fund Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/13 55 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, 2013, there were no open written options. K. Purchased Options The Fund may purchase put and call options in order to attempt to hedge against changes in the value of portfolio securities or to seek to increase total return. 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 value of contracts open during the year ended October 31, 2013 was $1,904,298. At October 31, 2013, there were no purchased options. L. 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 seek to increase the Fund's income or to 56 Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/13 attempt to hedge the risk of default on portfolio securities. When the Fund is 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 Fund as seller of protection 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 described above. 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. In addition, obligations under sell protection credit default swaps may be partially offset by net amounts received from settlement of buy protection credit default swaps entered into by the Fund for the same reference obligation with the same counterparty. The average value of swap contracts open during the year ended October 31, 2013, was $4,296,555. At October 31, 2013, there were no open credit default swaps. Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/13 57 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, 2015. Fees waived and expenses reimbursed during the year ended October 31, 2013 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 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 $136,306 in management fees, administrative costs and certain other reimbursements payable to PIM at October 31, 2013. 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, 2013, such out-of-pocket expenses by class of shares were as follows: 58 Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/13 -------------------------------------------------------------------------------- Shareholder Communications: -------------------------------------------------------------------------------- Class A $202,009 Class C 162,011 Class R -- Class Y 354,926 Class Z 1 -------------------------------------------------------------------------------- Total $718,947 ================================================================================ Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $95,484 in transfer agent fees and out-of-pocket reimbursements payable to PIMSS at October 31, 2013. 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, Class C and Class R shares. Pursuant to the Plan, the Fund pays PFD 0.25% of the average daily net assets attributable to Class A shares as compensation for personal services and/or account maintenance services or distribution services with regard to Class A shares. Pursuant to the Plan, the Fund also pays PFD 1.00% of the average daily net assets attributable to Class C shares. The fee for Class C shares consists of a 0.25% service fee and a 0.75% distribution fee paid as compensation for personal services and/or account maintenance services or distribution services with regard to Class C shares. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $18,388 in distribution fees payable to PFD at October 31, 2013. The Fund also has adopted a separate service plan for Class R shares (Service Plan). The Service Plan authorizes the Fund to pay securities dealers, plan administrators or other service organizations that agree to provide certain services to retirement plans or plan participants holding shares of the Fund a service fee of up to 0.25% of the Fund's average daily net assets attributable to Class R shares held by such plans. In addition, redemptions of each class of shares (except Class R, Class Y and Class 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 12 months 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 R, Class Y or Class Z shares. Proceeds from the CDSCs are paid to PFD. For the year ended October 31, 2013, CDSCs in the amount of $45,863 were paid to PFD. Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/13 59 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, 2013, the Subsidiary represented $132,750,344 or approximately 13.1% of the net assets of the Fund. 6. Forward Foreign Currency Contracts At October 31, 2013, 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.

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 is in the amount of $215 million. Under such facility, depending on the type of loan, interest on borrowings is payable at the London Interbank Offered Rate (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 the 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, 2013, the Fund had no borrowings under the credit facility. 62 Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/13 9.

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 consolidated 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 consolidated 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, 2013, 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 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 (one of the portfolios constituting the Pioneer Series Trust VI) at October 31, 2013, the consolidated 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, and the financial highlights for each of the periods indicated therein, in conformity with U.S. generally accepted accounting principles. /s/ Ernst & Young LLP Boston, Massachusetts December 23, 2013 64 Pioneer Multi-Asset Real Return Fund | Annual Report | 10/31/13 ADDITIONAL INFORMATION (unaudited) For the year ended October 31, 2013, certain dividends paid by the Fund may be subject to a maximum tax rate of 15%, as provided for by the Jobs and Growth Tax Relief Reconciliation Act (the Act) of 2003.

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.
