President's Letter

Dear Shareowner,

The U.S. economy continued its recovery through the first quarter of 2012, even
as broader global concerns weighed on investors. 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. Our strategy is to identify undervalued
individual securities with the greatest potential for success, carefully
weighing

risk against reward. Our teams of investment professionals continually monitor

investment goals.

                    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.

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.

Past performance is no guarantee of future results, and there is no guarantee
that market forecasts discussed will be realized.

or the factors influencing the Trust's historical or future performance are
statements of opinion as of the date of this report. These statements should
not be relied upon for any other purposes.

Call 1-800-225-6292 or visit us.pioneerinvestments.com for the most recent
month-end performance results. 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.

             assumptions in determining fair value of investments)

securities and senior loans are categorized as Level 2, and securities valued
using fair value methods (including valuation appraised securities) (other than

Notes to Financial Statements | 5/31/12 (unaudited)

1. 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:

        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.

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.

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 FUNDS
            APPROVAL OF AUDIT, AUDIT-RELATED, TAX AND OTHER SERVICES
                       PROVIDED BY THE INDEPENDENT AUDITOR

                  SECTION I - POLICY PURPOSE AND APPLICABILITY

The Pioneer Funds recognize the importance of maintaining the independence of
their outside auditors. Maintaining independence is a shared responsibility
involving Pioneer Investment Management, Inc ("PIM"), the audit committee and
the independent auditors.

The Funds recognize that a Fund's independent auditors: 1) possess knowledge of
the Funds, 2) are able to incorporate certain services into the scope of the
audit, thereby avoiding redundant work, cost and disruption of Fund personnel
and processes, and 3) have expertise that has value to the Funds. As a result,
there are situations where it is desirable to use the Fund's independent
auditors for services in addition to the annual audit and where the potential
for conflicts of interests are minimal. Consequently, this policy, which is
intended to comply with Rule 210.2-01(C)(7), sets forth guidelines and
procedures to be followed by the Funds when retaining the independent audit firm
to perform audit, audit-related tax and other services under those
circumstances, while also maintaining independence.

Approval of a service in accordance with this policy for a Fund shall also
constitute approval for any other Fund whose pre-approval is required pursuant
to Rule 210.2-01(c)(7)(ii).

In addition to the procedures set forth in this policy, any non-audit services
that may be provided consistently with Rule 210.2-01 may be approved by the
Audit Committee itself and any pre-approval that may be waived in accordance
with Rule 210.2-01(c)(7)(i)(C) is hereby waived.

Selection of a Fund's independent auditors and their compensation shall be
determined by the Audit Committee and shall not be subject to this policy.

                 firm, the scope of the Audit
