Pioneer Floating Rate Trust | Semiannual Report | 5/31/19 1 President's Letter Since 1928, active portfolio management based on in-depth, fundamental research, has been the foundation of Amundi Pioneer's investment approach. We believe an active management investment strategy is a prudent approach to investing, especially during periods of market volatility, which can result from any number of risk factors, including slow U.S. economic growth, rising interest rates, and geopolitical factors. Of course, in today's global economy, risk factors extend well beyond U.S. borders. In fact, it's not unusual for political and economic issues on the international front to cause or contribute to volatility in U.S. markets. At Amundi Pioneer, each security under consideration is researched by our team of experienced investment professionals, who communicate directly with the management teams of those companies. At the end of this research process, if we have conviction in a company's business model and management team, and regard the security as a potentially solid investment opportunity, an Amundi Pioneer portfolio manager makes an active decision to invest in that security. The portfolio resulting from these decisions represents an expression of his or her convictions, and strives to balance overall risk and return opportunity. As an example, the Standard & Poor's 500 Index -- the predominant benchmark for many U.S. Large-Cap Core Equity funds -- has 500 stocks. An Amundi Pioneer portfolio manager chooses to invest in only those companies that he or she believes can offer the most attractive opportunities to pursue the fund's investment objective, thus potentially benefiting the fund's shareowners. This process results in a portfolio that does not own all 500 stocks, but a much narrower universe. The same active decision to invest in a company is also applied when we decide to sell a security, either due to changing fundamentals, valuation concerns, or market risks. We apply this active decision-making across all of our equity, fixed-income, and global portfolios. Today, as investors, we have many options. It is our view that active management can serve shareholders well not only when markets are thriving, but also during periods of market volatility and uncertainty, thus making it a compelling investment choice. As you consider the many choices today, we encourage you to work with your financial advisor to develop an overall investment plan that addresses both your short- and long-term goals, and to implement such a plan in a disciplined manner. 2 Pioneer Floating Rate Trust | Semiannual Report | 5/31/19 We greatly appreciate the trust you have placed in us and look forward to continuing to serve you in the future. Sincerely, /s/ Lisa M. Jones Lisa M. Jones Head of the Americas, President and CEO of U.S. Amundi Pioneer Asset Management USA, Inc. May 31, 2019 Any information in this shareowner report regarding market or economic trends or the factors influencing the Trust's historical or future performance are statements of opinion as of the date of this report. Past performance is no guarantee of future results. Pioneer Floating Rate Trust | Semiannual Report | 5/31/19 3 Portfolio Management Discussion | 5/31/19 In the following interview, Jonathan Sharkey discusses the factors that influenced the performance of Pioneer Floating Rate Trust during the six-month period ended May 31, 2019. Mr. Sharkey, a senior vice president and a portfolio manager at Amundi Pioneer Asset Management, Inc., 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, 2019? A Pioneer Floating Rate Trust returned 3.34% at net asset value (NAV) and 2.62% at market price during the six-month period ended May 31, 2019, while the Trust's benchmark, the Standard & Poor's/Loan Syndications & Trading Association Leveraged Loan Index (the S&P/LSTA Index), returned 2.80% at NAV. Unlike the Trust, the S&P/LSTA Index does not use leverage. While the use of leverage increases investment opportunity, it also increases investment risk. During the same six-month period, the average return at NAV of the 31 closed end funds in Morningstar's Bank Loan Closed End Funds category (which may or may not be leveraged), was 2.25%, and the average return at market price of the 31 closed end funds in the same Morningstar category was 4.74%. The shares of the Trust were selling at a 14.23% discount to NAV on May 31, 2019. Comparatively, the shares of the Trust were selling at a 13.62% discount to NAV on November 30, 2018. The Trust's standardized, 30-day SEC yield was 5.78% on May 31, 2019*. Q How would you describe the investment environment in general, and for bank loans in particular, during the six-month period ended May 31, 2019? A Late 2018 saw investors' sentiment for so-called risk assets weaken, based on a range of concerns. The concerns included U.S.-China trade tensions, softening economic growth overseas, Italy's budget crisis, and other political uncertainties. In mid-December, the U.S. Federal Reserve System (the Fed) met expectations and raised its short-term interest-rate target to the 2.25% to 2.50% range, the fourth increase in calendar year 2018, while noting the potential for additional rate hikes in 2019. In combination with signs of slowing global economic growth and yet another setback in the "Brexit" negotiations in the United Kingdom, fears that the Fed would overshoot on * The 30-day SEC yield is a standardized formula that is based on the hypothetical annualized earning power (investment income only) of the Trust's portfolio securities during the period indicated. 4 Pioneer Floating Rate Trust | Semiannual Report | 5/31/19 interest rates led to a spike in volatility in the market for riskier assets. December 2018 saw the 10-year U.S. Treasury yield decline from 3.01% to 2.69%, as investors sought a safe haven from the market turmoil. Energy-related issues also declined sharply as crude oil prices plunged over the fourth quarter, mainly due to concerns about a weaker demand outlook and higher-than-expected supply driven in part by a loosening of U.S. sanctions on Iran. Risk-oriented assets rebounded sharply in January of 2019, however, as the Fed pivoted on monetary policy and took on a less aggressive tone, announcing an early end to its balance-sheet reduction program while also indicating it would become more "data dependent" with regard to interest-rate policy, thus putting further rate increases on hold, at least temporarily. In addition to the Fed's policy actions, weak economic data out of the euro zone and China led to renewed policy accommodations from both the European Central Bank (ECB) and the People's Bank of China. Modest progress on trade matters, a firming in oil prices, and positive corporate earnings reports also helped boost sentiment for credit-sensitive assets during the first quarter of 2019. While the overall pace of gains moderated and there was some interim market volatility, credit-sensitive assets continued to outperform interest-rate-sensitive issues through the end of April, before wavering again in May on another potential escalation in the U.S.-China trade situation, as the Trump administration announced plans to implement a 25% tariff on some $200 billion worth of Chinese goods. The bank-loan market finished the six-month period in positive territory, despite a very difficult first month (December 2018). The loan asset class returned -2.54% in December, as massive outflows from loan retail mutual funds had a major negative impact on the market. Comments from Fed Chair Powell indicating that future rate increases were likely to be curtailed were a major factor in the exodus from the loan market late in 2018, as the prospect of stabilizing interest rates lessened the attractiveness of the floating-rate feature of bank loans. The outflows were further fueled by heightened media coverage focused on the potential end of the current economic cycle and a possible recession in the near term, which would negatively impact the loan market. The negative effects of the market outflows on loan performance were exacerbated by low levels of liquidity at year-end, as collateralized loan obligation (CLO) formation paused after a record calendar year in terms of volume. Despite the struggles experienced in December, patient loan investors eventually benefited from the mostly positive credit-market conditions that existed between January and May 2019, as bank loans recouped the bulk of their late-2018 losses. Pioneer Floating Rate Trust | Semiannual Report | 5/31/19 5 Q What factors had the biggest effects on the Trust's benchmark-relative performance during the six-month period ended May 31, 2019? A The Trust's allocations across industries within the portfolio's loan positions had a modest impact on benchmark-relative performance, with positive contributions to relative returns coming from the portfolio's underweight to business & equipment services loans, and overweights to conglomerates and food products. The portfolio's out-of-benchmark allocation to high-yield corporate bonds also had a slight positive impact on the Trust's benchmark-relative performance over the six-month period. A portfolio underweight to technology -- electronics in particular -- detracted from the Trust's benchmark-relative performance for the six-month period, as did an overweight to aerospace & defense loans. Security selection results within the portfolio's allocation to the home furnishings sector also detracted from the Trust's benchmark-relative performance. Meanwhile, oil and gas-related holdings were a major drag on the Trust's absolute returns over the six-month period, given the general weakness in oil prices. With regard to individual loans held in the Trust's portfolio, positive contributions to benchmark-relative returns for the six-month period were led by PetSmart, which announced an initial public offering of its online retailer Chewy.com. The move is expected to improve the pet supply retailer's working capital. Other positive contributors to the Trust's benchmark-relative performance were positions in wireline company Windstream and cosmetics firm Revlon. Windstream's loan price benefited when the legal issues surrounding the spinoff of its communications infrastructure assets were resolved. Revlon's loans benefited from improved market sentiment as the company's sales rebounded following a period of inventory adjustments by key customers. On the downside, the portfolio's position in Serta Simmons Bedding (Serta) detracted from the Trust's benchmark-relative performance during the six-month period, due to a downgrade by credit-rating agencies. Serta's earnings results have been negatively affected by competition from direct-to-consumer sellers, and by the bankruptcies of two of its major customers. Another detractor from the Trust's benchmark-relative returns was the loan for Constellis, as earnings results for the security services firm have softened due to lower levels of government spending on overseas contingency operations. Finally, the loan price for energy exploration-and-production company Encino declined during the six-month period on oil price volatility, and so the position had a negative effect on the Trust's benchmark-relative results. 6 Pioneer Floating Rate Trust | Semiannual Report | 5/31/19 Q How did the level of leverage in the Trust change over the six-month period ended May 31, 2019? A The Trust employs leverage through a credit agreement. As of May 31, 2019, 31.9% of the Trust's total managed assets were financed by leverage, compared with 32.5% of the Trust's total managed assets financed by leverage at the start of the period on November 30, 2018. The Trust's leverage ratio decreased primarily due to a reduction in the absolute amount of funds borrowed by the Trust during the 6-month period. Q Did the Trust have any investments in any derivative securities during the six-month period ended May 31, 2019? If so, did the derivatives have any material effect on performance? A We invested the Trust in high-yield bond credit-default swap indices during the six-month period, principally to maintain portfolio liquidity. The derivatives had a slight positive impact on the Trust's performance. Q Did the Fund's distributions** to shareholders change during the six-month period ended May 31, 2019? A No, the Trust's distributions remained stable over the six-month period. Q What is your investment outlook and how have you positioned the Trust heading into the second half of its fiscal year? A We view loan fundamentals as positive and expect defaults in the loan market to remain manageable. To illustrate, the default rate on loans for the 12 months ended May 31, 2019, was 1.00% by loan volume, easily below the historical average of slightly more than 3%. The loan default rate by number of issuers was 1.56%, also below the long-term average. The default rate on loans held in the Trust's portfolio has remained well below that of the overall market. Potential risks to our outlook for the loan market include an unexpected decline in corporate earnings resulting from some combination of higher tariffs, rising wage growth, and slowing global economic growth. With regard to the Trust's positioning, the loan market has recently seen an uptick in the amount of leverage utilized in buyout activity, and so we have refrained from investing the portfolio in a number of the more levered deals. Instead, we have been emphasizing investments in loans to borrowers with strong cash flows, which we believe may help to ensure that those borrowers can pay their obligations should interest rates rise meaningfully from here, or if there is a downturn in market conditions. ** Distributions are not guaranteed. Pioneer Floating Rate Trust | Semiannual Report | 5/31/19 7 The average quality of loans held in the Trust's portfolio declined from BB- to B+ over the six-month period ended May 31, 2019. The change was driven primarily by the composition of the new-issue loan market over the period. We were comfortable with the changes in portfolio quality, as we believe economic conditions will remain favorable, at least in the near term. In terms of industries, we marginally increased the Trust's allocations to consumer cyclical and health care over the six-month period, while marginally decreasing exposures to communications, finance, and insurance. We have maintained the Trust's out-of-benchmark allocations to high-yield corporates, credit-default-swap indices, and insurance-linked securities (ILS). A significant move higher in interest rates appears to have become less of a near-term risk to the high-yield asset class, due to the aforementioned policy pivot by the Fed. Meanwhile, we view maintaining a modest position in ILS as helping to improve the Trust's long-term risk/reward profile, based on the higher yields and potential diversification*** benefits provided by the asset class. We believe bank loans demonstrated their investment value in last year's rising-rate environment, as the asset class substantially outperformed both high-yield and investment-grade corporate bonds prior to the Fed's policy reversal entering 2019. With the current U.S. recovery in its 10th year, we view any modest decline in the federal funds rate over the next few quarters as likely to support bank-loan market sentiment by helping to extend the credit cycle. We believe bank loans can continue to be an attractive element of income-oriented investors' portfolios, based on their relatively low correlation with other asset classes, even if loans are not as likely to benefit from rising interest rates over the near term. *** Diversification does not assure a profit nor protect against loss. Please refer to the Schedule of Investments on pages 13-40 for a full listing of Trust securities. All investments are subject to risk, including the possible loss of principal. In the past several years, financial markets have experienced increased volatility, depressed valuations, decreased liquidity, and heightened uncertainty. These conditions may continue, recur, worsen, or spread. The Trust may invest in derivative securities, which may include futures and options, for a variety of purposes, including: in an attempt to hedge against adverse changes in the marketplace of securities, interest rates or currency 8 Pioneer Floating Rate Trust | Semiannual Report | 5/31/19 exchange rates; as a substitute for purchasing or selling securities; to attempt to increase the Trust's return as a non-hedging strategy that may be considered speculative; and to manage portfolio characteristics. Using derivatives can increase fund losses and reduce opportunities for gains when the market prices, interest rates or the derivative instruments themselves behave in a way not anticipated by the Trust. These types of instruments can increase price fluctuation. The Trust is not limited in the percentage of its assets that may be invested in illiquid securities. Illiquid securities may be difficult to sell at a price reflective of their value at times when the Trust believes it is desirable to do so and the market price of illiquid securities 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 employs leverage through a revolving credit facility. Leverage creates significant risks, including the risk that the Trust's income or capital appreciation from investments purchased with the proceeds of leverage will not be sufficient to cover the cost of leverage, which may adversely affect the return for shareowners. The Trust is required to maintain certain regulatory and other asset coverage requirements in connection with its use of leverage. In order to maintain required asset coverage levels, the Trust may be required to reduce the amount of leverage employed by the Trust, alter the composition of its investment portfolio or take other actions at what might be inopportune times in the market. Such actions could reduce the net earnings or returns to shareowners over time, which is likely to result in a decrease in the market value of the Trust's shares. 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 may invest in insurance-linked securities (ILS). The return of principal and the payment of interest on ILS are contingent on the non-occurrence of a pre-defined "trigger" event, such as a hurricane or an earthquake of a specific magnitude. These risks may increase share price volatility. Any information in this shareowner report regarding market or economic trends or the factors influencing the Trust's historical or future performance are statements of opinion as of the date of this report. Past performance is no guarantee of future results.

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 shares of the Trust. Shares of 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 bought and sold in the open market through a stock exchange and frequently trade at prices lower than their NAV. NAV per share is total assets less total liabilities, which include preferred shares, or borrowings, as applicable, divided by the number of 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 through open-market purchases 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 or the sale of Trust shares. Had these fees and taxes been reflected, performance would have been lower. Index returns are calculated monthly, assume reinvestment of dividends and, unlike Trust returns, do not reflect any fees, expenses or sales charges. The index does not use leverage. You cannot invest directly in an index. 12 Pioneer Floating Rate Trust | Semiannual Report | 5/31/19 Schedule of Investments | 5/31/19 (unaudited)

For the six months ended May 31, 2019, there were no transfers between Levels 1 and 2. Securities with an aggregate market value of $13,286 transferred from Level 2 to Level 3 as there were no longer observable inputs available to determine their value. Net change in unrealized appreciation (depreciation) of Level 3 investments still held and considered Level 3 at May 31, 2019: $(211,916).

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 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 and the Trust may, as a secondary objective, also seek preservation of capital to the extent consistent with its investment objective of high current income. Amundi Pioneer Asset Management, Inc., an indirect, wholly owned subsidiary of Amundi and Amundi's wholly owned subsidiary, Amundi USA, Inc., serves as the Trust's investment adviser (the "Adviser"). Amundi Pioneer Distributor, Inc., an affiliate of Amundi Pioneer Asset Management, Inc., serves as the Trust's distributor (the "Distributor"). In August 2018, the Securities and Exchange Commission ("SEC") released a Disclosure Update and Simplification Final Rule. The Final Rule amends Regulation S-X disclosures requirements to conform them to U.S. Generally Accepted Accounting Principles ("U.S. GAAP") for investment companies. The Trust's financial statements were prepared in compliance with the new amendments to Regulation S-X. The Trust is an investment company and follows investment company accounting and reporting guidance under U.S. GAAP. U.S. GAAP requires the management of the Trust to 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: A. Security Valuation The net asset value of the Trust 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. Fixed-income securities are valued by using 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 Pioneer Floating Rate Trust | Semiannual Report | 5/31/19 47 ratings, or may use a pricing matrix or other fair value methods or techniques to provide an estimated value of the security or instrument. A pricing matrix is a means of valuing a debt security on the basis of current market prices for other debt securities, historical trading patterns in the market for fixed-income securities and/or other factors. Non-U.S. debt securities that are listed on an exchange will be valued at the bid price obtained from an independent third party pricing service. When independent third party pricing services are unable to supply prices, or when prices or market quotations are considered to be unreliable, the value of that security may be determined using quotations from one or more broker-dealers. Loan interests 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 third party 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. Event-linked bonds or catastrophe bonds are valued at the bid price obtained from an independent third party pricing service. Other insurance-linked securities (including sidecars, collateralized reinsurance and industry loss warranties) may be valued at the bid price obtained from an independent pricing service, or through a third party using a pricing matrix, insurance industry valuation models, or other fair value methods or techniques to provide an estimated value of the instrument. Equity securities that have traded on an exchange are valued by using 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 or, if both last bid and asked prices are not available, at the last quoted bid price. Last sale and bid and asked prices are provided by independent third party pricing services. In the case of equity securities not traded on an exchange, prices are typically determined by independent third party pricing services using a variety of techniques and methods. The value of foreign securities is translated into U.S. dollars based on foreign currency exchange rate quotations supplied by a third party pricing source. Trading in non-U.S. equity 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. The Trust may use a fair value model developed by an independent pricing service to value non-U.S. equity securities. 48 Pioneer Floating Rate Trust | Semiannual Report | 5/31/19 Swap contracts, including interest rate swaps, caps and floors (other than centrally cleared swap contracts) are valued at the dealer quotations obtained from reputable International Swap Dealers Association members. Centrally cleared swaps are valued at the daily settlement price provided by the central clearing counterparty. Shares of open-end registered investment companies (including money market mutual funds) are valued at such funds' net asset value. Shares of exchange-listed closed-end funds are valued by using the last sale price on the principal exchange where they are traded. Securities or loan interests for which independent pricing services or broker-dealers 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 a fair valuation team comprised of certain personnel of the Adviser pursuant to procedures adopted by the Trust's Board of Trustees. The Adviser's fair valuation team uses fair value methods approved by the Valuation Committee of the Board of Trustees. The Adviser's fair valuation team 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 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 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 significantly from exchange prices, and such differences could be material. At May 31, 2019, three securities were valued using fair value methods (in addition to securities valued using prices supplied by independent pricing services, broker-dealers or using a third party insurance pricing model) representing 0.28% of net assets. The value of these fair valued securities was $840,278. Pioneer Floating Rate Trust | Semiannual Report | 5/31/19 49 B. Investment Income and Transactions 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. 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 and net of income accrued on defaulted securities. Interest and dividend income payable by delivery of additional shares is reclassified as PIK (payment-in-kind) income upon receipt and is included in interest and dividend income, respectively. All discounts/premiums on purchase prices of 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. Security transactions are recorded as of trade date. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. C. 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. 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 on 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. 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 net taxable income and net realized capital gains, if any, to its shareowners. Therefore, no provision for federal income taxes is required. As of November 30, 2018, the Trust did not accrue any interest or penalties with respect to uncertain tax positions, which, if applicable, would be 50 Pioneer Floating Rate Trust | Semiannual Report | 5/31/19 recorded as an income tax expense on 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. GAAP. Distributions in excess of net investment income or net realized gains are temporary over distributions 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. The tax character of current year distributions payable will be determined at the end of the current taxable year. The tax character of distributions paid during the year ended November 30, 2018 was as follows:

-------------------------------------------------------------------------- 2018 -------------------------------------------------------------------------- Distributions paid from: Ordinary income $17,811,485 -------------------------------------------------------------------------- Total $17,811,485 ==========================================================================

The following shows the components of distributable earnings (losses) on a federal income tax basis at November 30, 2018:

-------------------------------------------------------------------------- 2018 -------------------------------------------------------------------------- Distributable earnings: Undistributed ordinary income $ 1,679,351 Capital loss carryforward (55,734,016) Other book/tax temporary differences (1,537,574) Unrealized depreciation (10,193,803) -------------------------------------------------------------------------- Total $(65,786,042) ==========================================================================

The difference between book basis and tax basis unrealized depreciation is attributable to the tax treatment of premium and amortization, adjustments relating to catastrophe bonds, the tax adjustments relating to credit default swaps and partnerships. E. 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's investments in foreign markets and countries with limited developing markets may subject the Trust Pioneer Floating Rate Trust | Semiannual Report | 5/31/19 51 to a greater degree of risk than investments in a developed market. These risks include disruptive political or economic conditions and the imposition of adverse governmental laws or currency exchange restrictions. The value of securities held by the Trust may go up or down, sometimes rapidly or unpredictably, due to general market conditions, such as real or perceived adverse economic, political or regulatory conditions, inflation, changes in interest rates, lack of liquidity in the bond markets or adverse investor sentiment. In the past several years, financial markets have experienced increased volatility, depressed valuations, decreased liquidity and heightened uncertainty. These conditions may continue, recur, worsen or spread. A general rise in interest rates could adversely affect the price and liquidity of fixed income securities. The Trust invests in below investment grade (high yield) debt securities, floating rate loans and insurance-linked securities. The Trust may invest in securities and other obligations of any credit quality, including those that are rated below investment grade, or are unrated but are determined by the Adviser to be of equivalent credit quality. 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. Below investment grade securities, including floating rate loans, involve greater risk of loss, are subject to greater price volatility, and may be less liquid and more difficult to value, especially during periods of economic uncertainty or change, than higher rated debt securities. Certain securities in which the Trust invests, including floating rate loans, once sold, may not settle for an extended period (for example, several weeks or even longer). The Trust will not receive its sale proceeds until that time, which may constrain the Trust's ability to meet its obligations. The Trust may invest in securities of issuers that are in default or that are in bankruptcy. 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. No active trading market may exist for many floating rate loans, and many loans are subject to restrictions on resale. Any secondary market may be subject to irregular trading activity and extended settlement periods. There is less readily available, reliable information about most floating rate loans than is the case for many other types of securities. Normally, the Adviser will seek to avoid receiving material, non-public information about the issuer of a loan either held by, or considered for investment by, the Trust, and this decision could adversely affect the Trust's investment performance. Loans may not be considered "securities," and purchasers, such as the Trust, therefore may not be entitled to rely on the anti-fraud protections afforded by federal securities laws. The Trust's investments in certain foreign markets or countries with limited developing markets may subject the Trust to a greater degree of risk 52 Pioneer Floating Rate Trust | Semiannual Report | 5/31/19 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 illiquid securities. Illiquid securities are securities that the Trust reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the securities. With the increased use of technologies such as the Internet to conduct business, the Trust is susceptible to operational, information security and related risks. While the Trust's Adviser has established business continuity plans in the event of, and risk management systems to prevent, limit or mitigate, such cyber-attacks, there are inherent limitations in such plans and systems including the possibility that certain risks have not been identified. Furthermore, the Trust cannot control the cybersecurity plans and systems put in place by service providers to the Trust such as Brown Brothers Harriman & Co., the Trust's custodian and accounting agent, American Stock Transfer & Trust Company ("AST"), the Trust's transfer agent. In addition, many beneficial owners of Trust shares hold them through accounts at broker-dealers, retirement platforms and other financial market participants over which neither the Trust nor Amundi Pioneer exercises control. Each of these may in turn rely on service providers to them, which are also subject to the risk of cyber-attacks. Cybersecurity failures or breaches at Amundi Pioneer or the Trust's service providers or intermediaries have the ability to cause disruptions and impact business operations potentially resulting in financial losses, interference with the Trust's ability to calculate its net asset value, impediments to trading, the inability of Trust shareowners to effect share purchases or receive distributions, loss of or unauthorized access to private shareowner information and violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, or additional compliance cost. Such costs and losses may not be covered under any insurance. In addition, maintaining vigilance against cyber-attacks may involve substantial costs over time, and system enhancements may themselves be subject to cyber-attacks. F. Insurance-Linked Securities ("ILS") The Trust invests in ILS. The Trust could lose a portion or all of the principal it has invested in an ILS, and the right to additional interest or dividend payments with respect to the security, upon the occurrence of one or more trigger events, as defined within the terms of an insurance-linked security. Trigger events, generally, are hurricanes, earthquakes, or other natural events of a specific size or magnitude that occur in a designated geographic region during a specified time period, and/or that involve losses or other metrics Pioneer Floating Rate Trust | Semiannual Report | 5/31/19 53 that exceed a specific amount. There is no way to accurately predict whether a trigger event will occur and, accordingly, ILS carry significant risk. The Trust is entitled to receive principal, and interest and/or dividend payments so long as no trigger event occurs of the description and magnitude specified by the instrument. In addition to the specified trigger events, ILS may expose the Trust to other risks, including but not limited to issuer (credit) default, adverse regulatory or jurisdictional interpretations and adverse tax consequences. The Trust's investments in ILS may include event-linked bonds. ILS also may include special purpose vehicles ("SPVs") or similar instruments structured to comprise a portion of a reinsurer's catastrophe-oriented business, known as quota share instruments (sometimes referred to as reinsurance sidecars), or to provide reinsurance relating to specific risks to insurance or reinsurance companies through a collateralized instrument, known as collateralized reinsurance. Structured reinsurance investments also may include industry loss warranties ("ILWs"). A traditional ILW takes the form of a bilateral reinsurance contract, but there are also products that take the form of derivatives, collateralized structures, or exchange-traded instruments. Where the ILS are based on the performance of underlying reinsurance contracts, the Trust has limited transparency into the individual underlying contracts, and therefore must rely upon the risk assessment and sound underwriting practices of the issuer. Accordingly, it may be more difficult for the Adviser to fully evaluate the underlying risk profile of the Trust's structured reinsurance investments, and therefore the Trust's assets are placed at greater risk of loss than if the Adviser had more complete information. Structured reinsurance instruments generally will be considered illiquid securities by the Trust. These securities may be difficult to purchase, sell or unwind. Illiquid securities also may be difficult to value. If the Trust is forced to sell an illiquid asset, the Trust may be forced to sell at a loss. G. Credit Default Swap Contracts A credit default swap is a contract between a buyer of protection and a seller of protection against a pre-defined credit event or an underlying reference obligation, which may be a single security or a basket or index of securities. The Trust may buy or sell credit default swap contracts to seek to increase the Trust's income, or to attempt to hedge the risk of default on portfolio securities. A credit default swap index is used to hedge risk or take a position on a basket of credit entities or indices. As a seller of protection, the Trust 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 Trust. In return, the Trust would receive from the counterparty a periodic stream of payments 54 Pioneer Floating Rate Trust | Semiannual Report | 5/31/19 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 Trust would keep the stream of payments and would have no payment obligation. The Trust may also buy credit default swap contracts in order to hedge against the risk of default of debt securities, in which case the Trust would function as the counterparty referenced above. As a buyer of protection, the Trust makes an upfront or periodic payment to the protection seller in exchange for the right to receive a contingent payment. An upfront payment made by the Trust, as the protection buyer, is recorded within the "Swap contracts, at value" line item on the Statement of Assets and Liabilities. Periodic payments received or paid by the Trust are recorded as realized gains or losses on the Statement of Operations. Credit default swap contracts are marked-to-market daily using valuations supplied by independent sources, and the change in value, if any, is recorded within the "Swap contracts, at value" line item on the Statement of Assets and Liabilities. 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 on the Statement of Operations. Credit default swap contracts involving the sale of protection may involve greater risks than if the Trust 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 Trust is a protection buyer and no credit event occurs, it will lose its investment. If the Trust is a protection seller and a credit event occurs, the value of the referenced debt instrument received by the Trust, together with the periodic payments received, may be less than the amount the Trust pays to the protection buyer, resulting in a loss to the Trust. 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 Trust for the same reference obligation with the same counterparty. Certain swap contracts that are cleared through a central clearinghouse are referred to as centrally cleared swaps. All payments made or received by the Trust are pursuant to a centrally cleared swap contract with the central clearing party rather than the original counterparty. Upon entering into a centrally cleared swap contract, the Trust is required to make an initial margin deposit, either in cash or in securities. The daily change in value on open centrally cleared contracts is recorded as "Variation margin for centrally cleared swaps" on the Statement of Assets and Liabilities. Cash received from or paid to the broker related to previous margin movement is held in a segregated account at the broker and is recorded as either "Due from broker Pioneer Floating Rate Trust | Semiannual Report | 5/31/19 55 for swaps" or "Due to broker for swaps" on the Statement of Assets and Liabilities. The amount of cash deposited with a broker as collateral at May 31, 2019, is recorded as "Swaps collateral" on the Statement of Assets and Liabilities. The average market value of credit default swap contracts open during the six months ended May 31, 2019, was $198,440. Open credit default swap contracts at May 31, 2019, are listed in the Schedule of Investments. H. Automatic Dividend Reinvestment Plan All 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 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 shares of the Trust on terms that differ from the terms of the Plan. Whenever the Trust declares a dividend on shares payable in cash, participants in the Plan will receive the equivalent in shares acquired by the Plan Agent either (i) through receipt of additional unissued but authorized shares from the Trust or (ii) by purchase of outstanding shares on the NYSE or elsewhere. If, on the payment date for any dividend, the net asset value per 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 shares. The number of newly issued shares to be credited to each account will be determined by dividing the dollar amount of the dividend by the net asset value per 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 share is greater than the market value (market discount), the Plan Agent will invest the dividend amount in shares acquired in open-market purchases. There are no brokerage 56 Pioneer Floating Rate Trust | Semiannual Report | 5/31/19 charges with respect to newly issued 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 be able to transfer the shares to another broker and continue to participate in the Plan. 2. Management Agreement The Adviser manages the Trust's portfolio. Management fees payable under the Trust's Advisory Agreement with the Adviser 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 or the issuance of debt securities), (ii) the issuance of preferred stock or other similar preference securities, and/or (iii) any other means. For the six months ended May 31, 2019 the net management fee was 0.70% (annualized) of the Trust's average daily managed assets, which was equivalent to 1.03% (annualized) of the Trust's average daily net assets. In addition, under the management and administration agreements, certain other services and costs, including accounting, regulatory reporting and insurance premiums, are paid by the Trust as administrative reimbursements. Included in "Due to affiliates" reflected on the Statement of Assets and Liabilities is $16,468 in management fees, administrative costs and certain other reimbursements payable to the Adviser at May 31, 2019. 3. Transfer Agent AST serves as the transfer agent with respect to the Trust's common shares. The Trust pays AST an annual fee, as is agreed to from time to time by the Trust and AST, for providing such services. In addition, the Trust reimbursed the transfer agent for out-of-pocket expenses incurred by the transfer agent related to shareowner communications activities such as proxy and statement mailings and outgoing phone calls. 4. Additional Disclosures about Derivative Instruments and Hedging Activities The Trust's use of derivatives may enhance or mitigate the Trust's exposure to the following risks: Interest rate risk relates to the fluctuations in the value of interest-bearing securities due to changes in the prevailing levels of market interest rates. Pioneer Floating Rate Trust | Semiannual Report | 5/31/19 57 Credit risk relates to the ability of the issuer of a financial instrument to make further principal or interest payments on an obligation or commitment that it has to the Trust. Foreign exchange rate risk relates to fluctuations in the value of an asset or liability due to changes in currency exchange rates. Equity risk relates to the fluctuations in the value of financial instruments as a result of changes in market prices (other than those arising from interest rate risk or foreign exchange rate risk), whether caused by factors specific to an individual investment, its issuer, or all factors affecting all instruments traded in a market or market segment. Commodity risk relates to the risk that the value of a commodity or commodity index will fluctuate based on increases or decreases in the commodities market and factors specific to a particular industry or commodity. The fair value of open derivative instruments (not considered to be hedging instruments for accounting disclosure purposes) by risk exposure at May 31, 2019 was as follows:

Unfunded loan commitments may be partially or wholly unfunded. During the contractual period, the Trust is obliged to provide funding to the borrower upon demand. A fee is earned by the Trust on the unfunded commitment and is recorded as interest income on the Statement of Operations. As of May 31, 2019, the Trust had the following unfunded loan commitments outstanding:

7. Credit Agreement Effective November 26, 2013, the Trust entered into a Revolving Credit Facility (the "Credit Agreement") with the Bank of Nova Scotia in the amount of $160,000,000. The Credit Agreement was established in conjunction with the redemption of all the Trust's auction market preferred shares. Effective November 23, 2016, the Trust extended the maturity of the Credit Agreement to November 22, 2019. At May 31, 2019, the Trust had a borrowing outstanding under the Credit Agreement totaling $139,450,000. The interest rate charged at May 31, 2019 was 3.53%. During the six months ended May 31, 2019, the average daily balance was $139,995,455 at an average interest rate of 3.42%. Interest expense of $2,452,500 in connection with the Credit Agreement is included on the Statement of Operations. Pioneer Floating Rate Trust | Semiannual Report | 5/31/19 59 The Trust is required to maintain 300% asset coverage with respect to amounts outstanding under the Credit Agreement. Asset coverage is calculated by subtracting the Trust's total liabilities not including any bank loans and senior securities, from the Trust's total assets and dividing such amount by the principal amount of the borrowing outstanding. 8. Subsequent Events A monthly dividend was declared on July 3, 2019 from undistributed and accumulated net investment income of $0.0625 per share payable July 31, 2019, to shareowners of record on July 16, 2019. 60 Pioneer Floating Rate Trust | Semiannual Report | 5/31/19 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 Amudi Pioneer Asset Management, Inc, 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.
