The U.S. unemployment rate fell to 8.1% in April, and some indicators suggest that it may continue to trend down. The housing market continued to improve, fueled in part by record-low mortgage rates. The risk of rising oil prices appeared to recede. The improved outlook helped U.S. equity markets to perform well in the first quarter, with the Standard & Poor's 500 Index rising by 12%. For bond investors, the riskier sectors of the bond market fared the best. The broad bond market, as measured by the Barclays Capital Aggregate Bond Index, rose by just 0.3%, while the high-yield bond market, as measured by the Bank of America Merrill Lynch High Yield Master II Index, rose by 5.15%. We are cautiously optimistic that the U.S. economy will continue to improve. But we are also closely monitoring macroeconomic concerns that could change the market's direction, such as the lingering debt woes in Europe, the state of the Chinese economy, and the U.S. government's fiscal situation. Clouds have continued to hover over Europe, as the exit of Greece from the Euro-zone remains a possibility. Meanwhile, China continues to face a potential slowdown in economic growth. In the U.S., tax increases and spending cuts scheduled to take effect at year-end should, unless fiscal policy changes, sharply reduce the budget deficit -- which would be very good for the country in the longer run -- but also could potentially stall U.S. economic growth in 2013. All of these considerations may lead to further market volatility. At Pioneer, we have long advocated the benefits of staying diversified* and investing for the long term. The strategy has generally performed well for many investors. Our advice, as always, is to work closely with a trusted financial advisor to discuss your goals and work together to develop an investment strategy that meets your individual needs. There is no single best strategy that works for every investor. Pioneer's investment professionals focus on finding good opportunities to invest in both equity and bond markets using the same disciplined investment approach we have used since 1928.

Pioneer Floating Rate Trust | Semiannual Report | 5/31/12 3 Portfolio Management Discussion | 5/31/12 Floating-rate bank loans generated healthy returns during most of the six-month period ended May 31, 2012, as credit-sensitive securities flourished against a backdrop of growing investor confidence. However, the market sagged somewhat in May 2012 amid new concerns about sovereign-debt problems in Europe and evidence of slowing economic growth in the United States. In the following interview, Jonathan Sharkey discusses the factors that affected the performance of Pioneer Floating Rate Trust over the six-month period ended May 31, 2012. Mr. Sharkey, vice president and portfolio manager at Pioneer, is responsible for the day-to-day management of the Trust. Q How did the Trust perform during the six-month period ended May 31, 2012? A Pioneer Floating Rate Trust returned 7.52% at net asset value and 6.65% at market price during the six months ended May 31, 2012, while the Trust's benchmark, the Barclays Capital U.S. High Yield Loans Index (the Barclays Index), returned 4.51%. During the same six-month period, the average return (at market price) of the 22 closed end funds in Lipper's Closed End Loan Participation Funds Category (which may or may not be leveraged) was 7.02%. The shares of the Trust were selling at a 0.4% premium to net asset value at the end of the six-month period on May 31, 2012. Unlike the Trust, the benchmark does not use leverage. While the use of leverage can increase investment opportunity, it also can increase investment risk. On May 31, 2012, the Trust's standard 30-day SEC yield was 7.96%. Q How would you describe the market environment for floating-rate loans during the six-month period ended May 31, 2012? A Early in the six-month period, evidence of continuing economic growth encouraged investors to seek out credit-sensitive, fixed-income investments in general, including floating-rate bank loans. Even though the pace of economic growth remained relatively slow, the credit-worthiness of most floating-rate loans became increasingly evident, encouraging a "risk-on" mentality among investors. High-yield fund managers and other types of institutional investors became attracted to the discounted prices at which many floating-rate loans were selling. In that environment, the Trust performed very well, both from its emphasis on floating-rate loans in the 4 Pioneer Floating Rate Trust | Semiannual Report | 5/31/12 portfolio and from its use of leverage, which served to boost results in a rising market. While concerns about European sovereign-debt problems had caused a pullback in the market in the weeks before the start of the six-month period, December 2011, the first month of the period, saw the market regain positive momentum. Bank loans produced positive returns in 2011, marking the 13th year in the last 14 that the asset class showed positive results. Although growth of loan mutual funds was anemic throughout the first quarter of 2012, loan returns were strong overall, as demand for loans outside of retail mutual funds grew in the face of stability in the fixed-income markets, healthy repayment activity for loans and the entry into the loan market of more investors, such as high-yield funds, pension funds and institutions. Collateralized loan obligations (CLOs), which in the aggregate account for 50% of the investor base purchasing bank loans, saw new demand which actually outpaced demand for all of 2011. The trend continued into April 2012. However, in May, the final month of the six-month period, the market for credit-sensitive securities, including floating-rate securities, declined as new worries surfaced about sovereign-credit problems in Europe, especially in Greece. Investors also grew apprehensive that any significant deterioration in the European economy could have a contagious effect on the U.S. economy. Nevertheless, the results for investments in floating-rate loans were strong over the full six-month period. Q What types of investments most influenced the Trust's performance during the six-month period ended May 31, 2012? A Although the Trust's portfolio of investments is overwhelmingly composed of floating-rate loans, exposures to two equity positions proved to be the most powerful influences on performance during the six-month period. Due to the financial reorganization of both Delphi Automotive and MGM, the Trust received equity shares (permissible holdings) in exchange for its bank loan positions. As the result of the financial reorganizations as well as improving business prospects for both corporations, the shares appreciated in value, providing significant boosts to the Trust's performance. Delphi Automotive is a producer of automotive components, while MGM is a producer of movies. Apart from the equity positions, the Trust's performance during the six-month period received the strongest support from investments in loans to health care institutions, which we have overweighted in the portfolio because of that sector's ability to produce consistent earnings, even in a sluggish economy. Loans to health care institutions had performed poorly in late 2011 due to uncertainty about how the Federal government's decisions about deficit reduction could affect the group. However, as prospects increased that health care would be less affected by the deficit-reduction Pioneer Floating Rate Trust | Semiannual Report | 5/31/12 5 talks, the values of the loans partially recovered later in the six-month period, and the Trust's investments gained in value. Individual holdings that contributed to the Trust's performance included: National Mentor, which provides home health care for people with disabilities; Carestream, a medical-technology corporation; Sun Health Care, which operates long-term facilities; and CCS Medical, a medical-device distributor. The Trust's investments in loans to Chrysler also helped performance, as the auto maker continued to strengthen its finances. The Trust did have some holdings that disappointed during the six-month period. Noteworthy underperformers in the Trust's portfolio included investments in loans to Azithromycin and Celtic Pharmaceutical, two smaller drug manufacturers; Broadstripe, a small regional cable telecom services provider; and Texas utility TXU. During the quarter, we lowered the Trust's dividend, primarily as the result of two corporate restructurings and, secondarily, because of some higher-coupon loans being refinanced at lower interest rates. In fact, nearly 15% of the Barclays Index was refinanced during the six-month period. Q How did the level of leverage employed by the Trust change over the six-month period ended May 31, 2012? A As of May 31, 2012, 36.7% of the Trust's total managed assets were financed by leverage, compared with 37.3% of the Trust's total managed assets financed by leverage at the start of the period on December 1, 2011. The change was due to fluctuations in the values of securities in which the Trust had invested, as the absolute amount of funds obtained through leverage had not changed. Q What is your investment outlook? A In the short term, we expect that the markets will continue to fluctuate in reaction to news about the economic situation in Europe and the political battles in the United States over spending, taxes and deficit reduction. Volatility could increase in the near future. We think the Trust is well positioned, however, even if volatility should increase. The overall credit quality of the Trust's holdings has improved somewhat in recent months, in part because we have invested in higher- quality loans as other loans have been retired by their corporate issuers. While our outlook has grown somewhat more cautious in recent weeks, we continue to believe that the domestic economy will grow modestly in 2012, with gross domestic product (GDP) potentially exceeding 2%. Most economic benchmarks remain positive, although improvement rates are far from robust. American corporations generally appear to be in sound financial health, having strengthened their balance sheets, and appear capable of 6 Pioneer Floating Rate Trust | Semiannual Report | 5/31/12 meeting all their loan obligations. Nevertheless, floating-rate bank loans still are selling at discounts to their par (face) values, despite their attractive prices and yields relative to other fixed-income investments, notably investment-grade corporate bonds. While the default rate for bank loans recently ticked up a bit, the rate remains below long-term averages and loans continue to be selling at prices that imply much higher default rates. That scenario potentially presents a solid investment opportunity. One of the benefits of floating-rate loans, as opposed to other income- oriented investments, is their potential to increase their yields as interest rates rise. While the U.S. Federal Reserve System has signaled its intention to keep short-term interest rates low, perhaps into 2014, we think investors in floating-rate loans still are being compensated while they wait for yield increases. Current yields offered by floating-rate loans remain attractive relative to other fixed-income investments, and loans continue to trade at discounts to their par values, thus leaving open the possibility for potential capital appreciation. Please refer to the Schedule of Investments on pages 13-40 for a full listing of Trust securities. Pioneer Floating Rate Trust | Semiannual Report | 5/31/12 7 The Trust may invest in derivative securities, which may include futures and options. These types of instruments can increase price fluctuation. The Trust is not limited in the percentage of its assets that may be invested in floating-rate senior loans and other securities deemed to be illiquid. Illiquid securities may be difficult to sell at a fair price at times when the Trust believes it is desirable to do so and their market price is generally more volatile than that of more liquid securities. Illiquid securities may be difficult to value, and investment of the Trust's assets in illiquid securities may restrict the Trust's ability to take advantage of market opportunities. The Trust currently uses leverage through the issuance of preferred shares. The Trust also is authorized to borrow from banks and to issue debt securities, which are other forms of leverage. Leverage creates significant risks, including the risk that the Trust's income or capital appreciation will not be sufficient to cover the cost of leverage, which may adversely affect the return for the holders of common shares. Since February of 2008, regularly scheduled auctions for the Trust's preferred shares have failed and preferred shareowners have not been able to sell their shares at auction. The Board of Trustees of the Trust has considered, and continues to consider, this issue. Investments in high-yield or lower-rated securities are subject to greater-than-average risk. The Trust may invest in securities of issuers that are in default or that are in bankruptcy. Investing in foreign and/or emerging markets securities involves risks relating to interest rates, currency exchange rates and economic and political conditions. The Trust is required to maintain certain regulatory and rating agency asset coverage requirements in connection with its outstanding preferred shares. In order to maintain required asset coverage levels, the Trust may be required to alter the composition of its investment portfolio or take other actions, such as redeeming preferred shares with the proceeds from portfolio transactions, at what might be inopportune times in the market. Such actions could reduce the net earnings or returns to holders of the Trust's common shares over time. These risks may increase share price volatility.

Current performance may be lower or higher than the performance data quoted. Performance data shown represents past performance. Past performance is no guarantee of future results. Investment return and market price will fluctuate, and your shares may trade below NAV, due to such factors as interest rate changes, and the perceived credit quality of borrowers. Total investment return does not reflect broker sales charges or commissions. All performance is for common shares of the Trust. Closed-end funds, unlike open-end funds, are not continuously offered. There is a one-time public offering and, once issued, shares of closed-end funds are sold in the open market through a stock exchange and frequently trade at prices lower than their NAV. NAV per common share is total assets less total liabilities, which includes preferred shares, divided by the number of common shares outstanding. When NAV is lower than market price, dividends are assumed to be reinvested at the greater of NAV or 95% of the market price. When NAV is higher, dividends are assumed to be reinvested at prices obtained under the Trust's dividend reinvestment plan. The performance table and graph do not reflect the deduction of fees and taxes that a shareowner would pay on Trust distributions. The Barclays Capital U.S. High Yield Loans Index measures the performance of high-yield loans. Since comparisons for the Barclays Index begin in 2006, the chart assumes an initial investment of $10,913, which is equal to the Trust's value at 11/30/2006. Index returns are calculated monthly, assume reinvestment of dividends and, unlike Trust returns, do not reflect any fees, expenses or sales charges. The indices do not employ leverage. You cannot invest directly in an index. 12 Pioneer Floating Rate Trust | Semiannual Report | 5/31/12 Schedule of Investments | 5/31/12 (unaudited) ----------------------------------------------------------------------------------------------- Principal S&P/Moody's Amount Ratings USD ($) (unaudited) Value ----------------------------------------------------------------------------------------------- ASSET BACKED SECURITY -- 0.0% (a) of Net Assets PHARMACEUTICALS, BIOTECHNOLOGY & LIFE SCIENCES --0.0%(a) Pharmaceuticals -- 0.0%(a) 100,234(b) NR/NR Pharma VI, 5.25%, 10/15/14 $ 90,211 ------------- Total Pharmaceuticals, Biotechnology & Life Sciences $ 90,211 ------------- TOTAL ASSET BACKED SECURITY (Cost $100,235) $ 90,211 ----------------------------------------------------------------------------------------------- COLLATERALIZED LOAN OBLIGATIONS -- 2.0% of Net Assets BANKS -- 2.0% Diversified Banks -- 0.6% 1,000,000(b)(c)(d) BB+/Ba2 Primus, Ltd., Series 2007-2A, Class D, 2.867%, 7/15/21 (144A) $ 663,270 1,000,000(b)(d) B+/Ba2 Rampart, Ltd., Series 2006-1A, Class D, 4.016%, 4/18/21 696,130 951,289(b)(d) CCC-/Ba3 Stanfield McLaren, Ltd., Series 2007-1A, Class B2L, 4.967%, 2/27/21 (144A) 657,702 ------------- $ 2,017,102 ----------------------------------------------------------------------------------------------- Thrifts & Mortgage Finance -- 1.4% 1,000,000(b)(d) BB+/Ba2 ACA, Ltd., Series 2007-1A, Class D, 2.817%, 6/15/22 (144A) $ 717,700 1,000,000(b)(d) BBB-/Ba1 Goldman Sachs Asset Management Plc, Series 2007-1A, Class D, 3.216%, 8/1/22 (144A) 761,850 1,000,000(b)(d) BBB/Baa3 Gulf Stream Sextant, Ltd., Series 2007-1A, Class D, 2.874%, 6/17/21 (144A) 747,340 1,000,000(b)(d) BB/Ba3 Landmark CDO, Ltd., Series 2007-9A, Class E, 3.967%, 4/15/21 (144A) 817,990 2,000,000(b)(d) BB+/Baa3 Stone Tower, Ltd., Series 2007-6A, Class C, 1.816%, 4/17/21 (144A) 1,332,320 ------------- $ 4,377,200 ------------- Total Banks $ 6,394,302 ----------------------------------------------------------------------------------------------- TOTAL COLLATERALIZED LOAN OBLIGATIONS (Cost $6,696,776) $ 6,394,302 ----------------------------------------------------------------------------------------------- SENIOR SECURED FLOATING RATE LOAN INTERESTS -- 138.8% of Net Assets* AUTOMOBILES & COMPONENTS -- 6.3% Auto Parts & Equipment -- 4.1% 2,754,304 BB-/Ba3 Allison Transmission, Inc., Term Loan B-1, 2.74%, 8/7/14 $ 2,721,787 The accompanying notes are an integral part of these financial statements.

Organization and Significant Accounting Policies Pioneer Floating Rate Trust (the "Trust") was organized as a Delaware statutory trust on October 6, 2004. Prior to commencing operations on December 28, 2004, the Trust had no operations other than matters relating to its organization and registration as a non-diversified, closed-end management investment company under the Investment Company Act of 1940, as amended. The Trust is a diversified fund. The investment objective of the Trust is to provide a high level of current income. The Trust will, as a secondary objective, also seek preservation of capital to the extent consistent with its primary objective of high current income. The Trust's financial statements have been prepared in conformity with U.S. generally accepted accounting principles that require the management of the Trust 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 gain or loss 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 Trust in the preparation of its financial statements, which are consistent with those policies generally accepted in the investment company industry: A. Security Valuation Security transactions are recorded as of trade date. Senior floating rate loan interests (senior loans) are valued in accordance with guidelines established by the Board of Trustees at the mean between the last available bid and asked prices from one or more brokers or dealers as obtained from Loan Pricing Corporation an independent pricing service. Senior loans for which no reliable price quotes are available will be valued by Loan Pricing Corporation through the use of pricing matrices to determine valuations. Fixed-income securities with remaining maturity of more than sixty days are valued at prices supplied by independent pricing services, which consider such factors as market prices, market events, quotations from one or more brokers, Treasury spreads, yields, maturities and ratings. Valuations may be supplemented by dealers and other sources, as required. 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 46 Pioneer Floating Rate Trust | Semiannual Report | 5/31/12 or less generally are valued at amortized cost. Money market mutual funds are valued at net asset value. Trading in the 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 Trust'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 using fair value methods pursuant to procedures adopted by the Board of Trustees. The Trust 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 Trust'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 Trust's securities may differ from exchange prices. At May 31, 2012, twenty-four securities were valued using fair value methods (in addition to securities valued using prices supplied by independent pricing services) representing 3.0% of net assets applicable to common shareowners. 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. Discounts and premiums on debt securities are accreted or amortized, respectively, daily, into interest income on an effective yield to maturity basis with a corresponding increase or decrease in the cost basis of the security. Premiums and discounts related to certain mortgage-backed securities are amortized or accreted in proportion to the monthly paydowns. Interest income, including income on interest bearing cash accounts, is recorded on an accrual basis, net of unrecoverable foreign taxes withheld at the applicable country rates. 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 Trust becomes aware of the ex-dividend data in the exercise of reasonable diligence. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. B. Foreign Currency Translation The books and records of the Trust are maintained in U.S. dollars. Amounts denominated in foreign currencies are translated into U.S. dollars using current exchange rates. Pioneer Floating Rate Trust | Semiannual Report | 5/31/12 47 Net realized gains and losses on foreign currency transactions, if any, represent, among other things, the net realized gains and losses on foreign currency contracts, disposition of foreign currencies and the difference between the amount of income accrued and the U.S. dollars actually received. Further, the effects of changes in foreign currency exchange rates on investments are not segregated in the Statement of Operations from the effects of changes in market prices of those securities but are included with the net realized and unrealized gain or loss on investments. C. Forward Foreign Currency Contracts The Trust may enter into forward foreign currency contracts (contracts) for the purchase or sale of a specific foreign currency at a fixed price on a future date. All contracts are marked to market daily at the applicable exchange rates, and any resulting unrealized gains or losses are recorded in the Trust's financial statements. The Trust records realized gains and losses at the time a portfolio hedge is offset by entry into a closing transaction or extinguished by delivery of the currency. Risks may arise upon entering into these contracts from the potential inability of counterparties to meet the terms of the contracts and from unanticipated movements in the value of foreign currencies relative to the U.S. dollar (see Note 5). D. Federal Income Taxes It is the Trust's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income and net realized capital gains, if any, to its shareowners. Therefore, no federal income tax provision is required. Tax years for the prior three fiscal years remain subject to examination by federal and state tax authorities. The amounts and characterizations of distributions to shareowners for financial reporting purposes are determined in accordance with federal income tax rules. Therefore, the sources of the Trust's distributions may be shown in the accompanying financial statements as from or in excess of net investment income or as from net realized gain (loss) on investment and foreign currency transactions, or from paid-in capital, depending on the type of book/tax differences that may exist. The tax character of distributions paid to common and preferred shareowners will be determined at the end of the fiscal year. Distribution paid during the year ended November 30, 2011 was as follows: ---------------------------------------------------------------------------- 2011 ---------------------------------------------------------------------------- Distributions paid from: Ordinary income $25,801,555 ---------------------------------------------------------------------------- Total $25,801,555 ============================================================================ 48 Pioneer Floating Rate Trust | Semiannual Report | 5/31/12 The following shows the components of distributable earnings (losses) on a federal income tax basis at November 30, 2011: ---------------------------------------------------------------------------- 2011 ---------------------------------------------------------------------------- Distributable earnings: Undistributed ordinary income $ 7,429,692 Capital loss carryforward (120,602,379) Dividends payable (34,167) Unrealized depreciation (44,262,119) ---------------------------------------------------------------------------- Total $ (157,468,973) ============================================================================ The difference between book-basis and tax-basis unrealized depreciation is primarily attributable to the difference between book and tax amortization methods for premiums and discounts on fixed-income securities, and the realization of unrealized gain on investments in passive foreign investment companies. E. Risk Information regarding the Trust's principal risks is contained in the Trust's original offering prospectus with additional information included in the Trust's shareowner reports issued from time to time. Please refer to those documents when considering the Trust's principal risks. At times, the Trust's investments may represent industries or industry sectors that are interrelated or have common risks, making the Trust more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. The Trust invests primarily in senior floating rate loans (Senior Loans). The Trust may also invest in other floating and variable rate instruments, including second lien loans, investment grade fixed-income debt securities and high yield, high risk corporate bonds. The Trust may also invest in below investment grade securities. Below investment grade securities are commonly referred to as "junk bonds" and are considered speculative with respect to the issuer's capacity to pay interest and repay principal. 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 Trust may invest in securities of issuers that are in default or that are in bankruptcy. Additionally, the Trust may invest in "event-linked" bonds, which sometimes are referred to as "insurance-linked" or "catastrophe" 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. In addition to the specified trigger events, event-linked bonds may expose the Trust to other risks, including but not limited to issuer (credit) default, adverse regulatory or jurisdictional interpretations and adverse tax consequences. Pioneer Floating Rate Trust | Semiannual Report | 5/31/12 49 The Trust's investments in certain foreign markets or countries with limited developing markets may subject the Trust to a greater degree of risk than in a developed market. These risks include disruptive political or economic conditions and the possible imposition of adverse governmental laws or currency exchange restrictions. The Trust is not limited in the percentage of its assets that may be invested in Senior Loans and other securities deemed to be illiquid. Illiquid securities may be difficult to sell at a fair price reflective of their value at times when the Trust believes it is desirable to do so and their market price is generally more volatile than that of more liquid securities. Illiquid securities may be more difficult to value and investment of the Trust's assets in illiquid securities may restrict the Trust's ability to take advantage of market opportunities. F. Repurchase Agreements With respect to repurchase agreements entered into by the Trust, 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 Trust's custodian or a subcustodian of the Trust. The Trust's investment adviser, Pioneer Investment Management, Inc. (PIM), is responsible for determining that the value of the collateral remains at least equal to the repurchase price. G. Automatic Dividend Reinvestment Plan All common shareowners whose shares are registered in their own names automatically participate in the Automatic Dividend Reinvestment Plan (the Plan), under which participants receive all dividends and capital gain distributions (collectively, dividends) in full and fractional common shares of the Trust in lieu of cash. Shareowners may elect not to participate in the Plan. Shareowners not participating in the Plan receive all dividends and capital gain distributions in cash. Participation in the Plan is completely voluntary and may be terminated or resumed at any time without penalty by notifying American Stock Transfer & Trust Company, the agent for shareowners in administering the Plan (the Plan Agent), in writing prior to any dividend record date; otherwise such termination or resumption will be effective with respect to any subsequently declared dividend or other distribution. If a shareowner's shares are held in the name of a brokerage firm, bank or other nominee, the shareowner can ask the firm or nominee to participate in the Plan on the shareowner's behalf. If the firm or nominee does not offer the Plan, dividends will be paid in cash to the shareowner of record. A firm or nominee may reinvest a shareowner's cash dividends in common shares of the Trust on terms that differ from the terms of the Plan. 50 Pioneer Floating Rate Trust | Semiannual Report | 5/31/12 Whenever the Trust declares a dividend on common shares payable in cash, participants in the Plan will receive the equivalent in common shares acquired by the Plan Agent either (i) through receipt of additional unissued but authorized common shares from the Trust or (ii) by purchase of outstanding common shares on the New York Stock Exchange or elsewhere. If, on the payment date for any dividend, the net asset value per common share is equal to or less than the market price per share plus estimated brokerage trading fees (market premium), the Plan Agent will invest the dividend amount in newly issued common shares. The number of newly issued common shares to be credited to each account will be determined by dividing the dollar amount of the dividend by the net asset value per common share on the date the shares are issued, provided that the maximum discount from the then current market price per share on the date of issuance does not exceed 5%. If, on the payment date for any dividend, the net asset value per common share is greater than the market value (market discount), the Plan Agent will invest the dividend amount in common shares acquired in open-market purchases. There are no brokerage charges with respect to newly issued common shares. However, each participant will pay a pro rata share of brokerage trading fees incurred with respect to the Plan Agent's open-market purchases. Participating in the Plan does not relieve shareowners from any federal, state or local taxes which may be due on dividends paid in any taxable year. Shareowners holding Plan shares in a brokerage account may not be able to transfer the shares to another broker and continue to participate in the Plan. 2. Management Agreement PIM, a wholly owned indirect subsidiary of UniCredit S.p.A. (UniCredit), manages the Trust's portfolio. Management fees payable under the Trust's Advisory Agreement with PIM are calculated daily at the annual rate of 0.70% of the Trust's average daily managed assets. "Managed assets" means (a) the total assets of the Trust, including any form of investment leverage, minus (b) all accrued liabilities incurred in the normal course of operations, which shall not include any liabilities or obligations attributable to investment leverage obtained through (i) indebtedness of any type (including, without limitation, borrowing through a credit facility of the issuance of debt securities), (ii) the issuance of preferred stock or other similar preference securities, and/or (iii) any other means. For the period ended May 31, 2012, the net management fee was 0.70% of the Trust's average daily managed assets, which was equivalent to 1.10% of the Trust's average daily net assets attributable to the common shareowners. In addition, under PIM's management and administration agreements, certain other services and costs are paid by PIM and reimbursed by the Trust. At May 31, 2012, $391,595 was payable to PIM related to management costs, administrative costs and certain other reimbursements and is included in "Due Pioneer Floating Rate Trust | Semiannual Report | 5/31/12 51 to affiliates" and "Administration fee" on the Statement of Assets and Liabilities. Effective April 2, 2012, PIM has retained Brown Brothers Harriman & Co. (BBH) to provide certain administrative and accounting services to the Trust on its behalf. For such services, PIM pays BBH a monthly fee at an annual rate of 0.025% of the Trust's average daily managed assets subject to a minimum monthly fee of $6,250. Previously, PIM had retained State Street Bank and Trust Company (State Street) provide such services. PIM paid State Street a monthly fee at an annual rate of 0.07% of the Trust's average daily managed assets up to $500 million and 0.03% for average daily managed assets in excess of $500 million, subject to a minimum monthly fee of $10,000. Neither BBH nor State Street had received compensation directly from the Trust for providing such services. 3. Transfer Agents Pioneer Investment Management Shareholder Services, Inc. (PIMSS), a wholly owned indirect subsidiary of UniCredit, through a sub-transfer agency agreement with American Stock Transfer & Trust Company, provides substantially all transfer agent and shareowner services related to the Trust's common shares at negotiated rates. Deutsche Bank Trust Company Americas (Deutsche Bank) is the transfer agent, registrar, dividend paying agent and auction agent with respect to the Trust's Auction Market Preferred Shares (AMPS). The Trust pays Deutsche Bank an annual fee, as is agreed to from time to time by the Trust and Deutsche Bank, for providing such services. In addition, the Trust reimburses PIMSS for out-of-pocket expenses incurred by PIMSS related to shareowner communications activities such as proxy and statement mailings and outgoing phone calls. 4. Expense Offset Arrangement The Trust has entered into an arrangement with its custodian whereby credits realized as a result of uninvested cash balances are used to reduce a portion of the Trust's custodian expenses. For the six months ended May 31, 2012, the Trust expenses were not reduced under such arrangement. 5. Forward Foreign Currency Contracts During the six months ended May 31, 2012, the Trust entered into various forward foreign currency contracts that obligate the Trust 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 Trust may close out such contract by entering into an offsetting contract. The average value of contracts open during the six months ended May 31, 2012 was $1,921,667. At May 31, 2012, the Trust had no open forward portfolio or settlement contracts. 52 Pioneer Floating Rate Trust | Semiannual Report | 5/31/12 6. Unfunded Loan Commitments As of May 31, 2012, the Trust had an unfunded loan commitments amounting to $1,340,193 (excluding unrealized depreciation on this commitment of $6,031 as of May 31, 2012) which could be extended at the option of the borrower, pursuant to the following loan agreement: --------------------------------------------------------------------------------------- Unrealized Borrower Par Cost Value Gain (Loss) --------------------------------------------------------------------------------------- National Specialty Hospitals, Inc., Initial Term Loan $196,782 $196,782 $191,125 $ (5,657) Tronox Pigments (Netherlands) B.V., Delayed Draw Term Loan $171,429 $171,429 $170,500 $ (929) Wendy's International Inc., Delayed Term Loan $971,982 $962,402 $962,957 $ 555 --------------------------------------------------------------------------------------- Total $ 6,031 ======================================================================================= In addition, the Trust had the following bridge loan commitment outstanding at May 31, 2012: --------------------------------------------------------------------------------------- Net Unrealized Loan Shares Cost Value Gain --------------------------------------------------------------------------------------- Wolverine World Wide, Inc., Senior Unsecured Bridge Loan 1,800,000 $1,800,000 $1,800,000 $-- --------------------------------------------------------------------------------------- Total $-- ======================================================================================= 7. Trust Shares There are an unlimited number of common shares of beneficial interest authorized. Transactions in common shares of beneficial interest for the period ended May 31, 2012 and November 30, 2011 were as follows: ------------------------------------------------------------------------------- 5/31/12 11/30/11 ------------------------------------------------------------------------------- Shares outstanding at beginning of period 24,640,650 24,536,526 Reinvestment of distributions 44,331 104,124 ------------------------------------------------------------------------------- Shares outstanding at end of period 24,684,981 24,640,650 =============================================================================== The Trust may classify or reclassify any unissued shares of beneficial interest into one or more series of preferred shares of beneficial interest. As of May 31, 2012, there were 7,298 AMPS as follows: Series M7-2,434, Series W7,-2,432 and Series TH7-2,432. Pioneer Floating Rate Trust | Semiannual Report | 5/31/12 53 Notes to Financial Statements | 5/31/12 (unaudited) Dividends on Series M7, Series W7, and Series TH7, are cumulative at a rate which is to be reset every seven days based on the results of an auction. An auction fails if there are more AMPS offered for sale than there are buyers. When an auction fails, the dividend rate for the period will be the maximum rate on the auction dates described in the prospectus for the AMPS. Preferred shareowners are not able to sell their AMPS at an auction if the auction fails. Since February 2008, the Trust's auctions related to the AMPS have failed. The maximum rate for each series is the greater of 125% of the one week LIBOR rate or the LIBOR rate plus a spread of 1.25%. Dividend rates on AMPS ranged from 1.409% to 1.505% during the six months ended May 31, 2012. The Trust may not declare dividends or make other distributions on its common shares or purchase any such shares if, at the time of the declaration, distribution or purchase, the Trust does not comply with the asset coverage ratios described in the prospectus for the AMPS. The AMPS are redeemable at the option of the Trust, in whole or in part, on any dividend payment date at $25,000 per share plus any accumulated or unpaid dividends, whether or not declared. The AMPS are also subject to mandatory redemption at $25,000 per share plus any accumulated or unpaid dividends, whether or not declared, if certain requirements relating to the composition of the assets and liabilities of the Trust as set forth in the Statement of Preferences are not satisfied. The holders of AMPS have voting rights equal to the holders of the Trust's common shares (one vote per share) and will vote together with holders of the common shares as a single class. Holders of AMPS are also entitled to elect two of the Trust's Trustees. In addition, the Investment Company Act of 1940, as amended, requires that along with approval by shareowners that might otherwise be required, the approval of the holders of a majority of any outstanding preferred shares, voting separately as a class, would be required to (a) adopt any plan of reorganization that would adversely affect the preferred shares and (b) take any action requiring a vote of security holders, including, among other things, changes in the Trust's subclassification as a closed-end management investment company or changes in its fundamental investment restrictions. 54 Pioneer Floating Rate Trust | Semiannual Report | 5/31/12 8. Additional Disclosures about Derivative Instruments and Hedging Activities: The effect of derivative instruments on the Statement of Operations for the six months ended May 31, 2012 was as follows: ------------------------------------------------------------------------------------------------------- Derivatives Not Change in Accounted for as Realized Unrealized Hedging Instruments Loss on Loss on Under Accounting Location of Gain or (Loss) Derivatives Derivatives Standards Codification on Derivatives Recognized Recognized Recognized (ASC) 185 in Income in Income in Income ------------------------------------------------------------------------------------------------------- Forward Foreign Currency Contracts Net realized loss on forward foreign $(60,758) currency contracts and other assets and liabilities denominated in foreign currencies Forward Foreign Currency Contracts Change in net unrealized gain (loss) $49,727 on forward foreign currency contracts and other assets and liabilities denominated in foreign currencies 9. Pending Litigation The Trust is currently involved in litigation matters relating to Trust investments. The Trust believes these claims are without merit and is defending both vigorously. At May 31, 2012, it is reasonably possible that adverse outcomes may result. Currently, the amount of either judgment cannot be reasonably estimated. 10. Subsequent Events The Board of Trustees of the Trust declared on June 4, 2012 a dividend from undistributed net investment income of $0.075 per common share payable June 29, 2012, to common shareowners of record on June 15, 2012. Subsequent to May 31, 2012, dividends declared and paid on preferred shares totaled $219,509 in aggregate for the two outstanding preferred share series through June 30, 2012. On July 12, 2012, Moody's Investor Service, Inc. ("Moody's") downgraded the ratings of debt and preferred shares issued by nearly all equity, municipal bond and taxable fixed income closed-end funds in the industry, including preferred shares ("AMPS") issued by the Trust. The ratings actions were the result of a decision by Moody's to revise its ratings methodology and were not related specifically to any changes in the portfolio investments or structure of the Trust. The rating downgrade will result in the Trust having to pay a slightly higher dividend rate on its AMPS. Pioneer Floating Rate Trust | Semiannual Report | 5/31/12 55 ADDITIONAL INFORMATION (unaudited) During the period, there have been no material changes in the Trust's investment objective or fundamental policies that have not been approved by the shareowners.

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.
