AUGUST 31, 2005 A Letter From the President Dear Shareholder Amid what we've coined a "muddle through" year for the financial markets, the major market benchmarks managed to post positive results for the current reporting period: Total Returns as of August 31, 2005 6-month 12-month U.S. equities (Standard & Poor's 500 Index) +2.33% +12.56% Small-cap U.S. equities (Russell 2000 Index) +5.75% +23.10% International equities (MSCI Europe Australasia Far East Index) +1.98% +23.58% Fixed income (Lehman Brothers Aggregate Bond Index) +2.85% + 4.15% Tax-exempt fixed income (Lehman Brothers Municipal Bond Index) +2.85% + 5.31% High yield bonds (Credit Suisse First Boston High Yield Index) +1.35% + 8.98% Since June 2004, the Federal Reserve Board (the Fed) has tirelessly advanced its interest rate-hiking program, bringing the federal funds rate to 3.5% by August 31 (and to 3.75% on September 20). Economists and investors have struggled to project the Fed's future moves, vacillating from expectations for an impending end to monetary tightening to fears that the central bank may increase interest rates more than is necessary to moderate economic growth and keep inflation in check. Most recently, the devastation of Hurricane Katrina added a new element of ambiguity in terms of its impact on the economy and Fed sentiment. Many now believe the Fed will suspend its interest rate-hiking campaign at some point this year. Equity market returns over the past several months have reflected a degree of investor uncertainty. After a strong finish to 2004, the S&P 500 Index posted gains in four of the first eight months of 2005. Up to this point, strong corporate earnings reports and low long-term bond yields have worked in favor of equities. Factors that pose the greatest risks to stocks include record- high oil prices, continued interest rate hikes and the possibility for disappointing earnings for the remainder of the year. Fixed income markets have fared relatively well in the face of monetary tightening. As the short end of the yield curve moved in concert with Fed interest rate hikes, long-term bond yields remained low, perpetuating the yield curve flattening trend. Because bond prices move in the opposite direction of yields, the result has been that longer-term bonds have outperformed short-term bonds. At period end, the spread between two-year and 10-year Treasury yields was just 18 basis points (.18%). Financial markets are likely to face continued crosscurrents for the remainder of 2005, particularly as the economy digests the impact of Hurricane Katrina. Nevertheless, opportunities do exist and we encourage you to work with your financial advisor to diversify your portfolio among a variety of asset types. This can help to diffuse risk while also tapping into the potential benefits of a broader range of investment alternatives. As always, we thank you for trusting Merrill Lynch Investment Managers with your investment assets. Sincerely, (Robert C. Doll, Jr.) Robert C. Doll, Jr. President and Director/Trustee MERRILL LYNCH SENIOR FLOATING RATE FUND, INC. AUGUST 31, 2005 A Discussion With Your Fund's Portfolio Manager The Fund ended the period with an overall credit quality positioned toward the center of the leveraged loan market, rather than barbelled at the high and low ends of the quality spectrum. Describe market conditions during the past year. The past year has been characterized by heavy investor participation in the leveraged loan market, primarily through collateralized loan obligations, which are debt securities backed by pools of commercial bank loans, and through new closed-end funds and net subscriptions to open-end mutual funds. There was a notable increase in the issuance of leveraged loan securities in response to stepped-up demand from investors. The excess cash in the loan market has led to increased refinancing activity and reductions in the margin above the London InterBank Offered Rate (LIBOR) paid by borrowers, leading to higher bids in the secondary market. Although these factors had a somewhat negative effect on the market, a low default rate and the rise in the LIBOR enhanced the performance of leveraged loans during the year. According to Standard & Poor's Leveraged Commentary & Data (LCD), the average margin above LIBOR for new-issue institutional tranches rated BB/BB- was 178 basis points (1.78%) at August 31, 2005, compared to 213 basis points in August 2004. The average new-issue margin above LIBOR for institutional tranches rated B+/B ended the fiscal year at 250 basis points, 41 basis points lower than its level at the end of August 2004. Meanwhile, the three-month LIBOR rose from 1.80% to 3.87% during the year, outweighing the effects of the spread compression. Despite the significant increase in the LIBOR, we believe the Federal Reserve Board is getting close to ending its bias toward a more restrictive monetary policy and, consequently, we do not expect the LIBOR to rise much further. Also benefiting the asset class, the default rate for the leveraged loan market remained at historically low levels throughout the year (including the market downturn in May) as fundamental credit quality generally remained strong across the market. The Standard & Poor's LCD lagging 12-month default rate, by principal amount, was 1.43% as of August 31, 2005, up from 0.88% one year earlier. How did the Fund perform during the fiscal year in light of the existing market conditions? For the 12-month period ended August 31, 2005, the Common Stock of Merrill Lynch Senior Floating Rate Fund, Inc. had a net annualized yield of 4.28%, based on a year-end per share net asset value of $9.01 and $.385 per share income dividends. For the same period, the total investment return on the Fund's Common Stock was +5.38%, based on a change in per share net asset value from $8.91 to $9.01, and assuming reinvestment of all distributions. For the same period, the Fund's benchmark, the Credit Suisse First Boston (CSFB) Leveraged Loan Index, recorded a total return of +5.95%. For the six-month period ended August 31, 2005, the total investment return on the Fund's Common Stock was +2.19%, based on a change in per share net asset value from $9.02 to $9.01, and assuming reinvestment of all distributions. The Fund's benchmark returned +2.85% for the same period. What factors most influenced Fund performance? The portfolio's holdings in the transportation, energy - other and steel sectors had a negative effect on Fund results for the fiscal year. Conversely, security selection in chemicals, U.S. cable and services benefited performance. Our holding in Sirva Worldwide, a moving and relocation service provider, hindered the Fund's return in the transportation sector. The value of the loan security fell amid investor concerns about the company's internal audit procedures and reports that business in its European division was slowing. The company has announced plans to sell a non-core insurance subsidiary, which should improve its liquidity and leverage. In the energy - other sector, many companies repaid at par value debt that had been marked at prices above par. At period-end, none of our remaining holdings in the sector were priced below par. The primary driver of the Fund's lagging return in the steel sector was the Acme Metals, Inc. stock that, in addition to cash payments, we received as part of a loan restructuring. The stock price declined because the payments constituted a return of principal, and therefore reduced the value of the company. MERRILL LYNCH SENIOR FLOATING RATE FUND, INC. AUGUST 31, 2005 The strong performance in the chemical sector was broad-based, as increased demand sparked an industry-wide rally. Most notably, we sold our holding in Pioneer Companies, Inc. common stock after it enjoyed strong performance amid a rally in the chlor-alkali industry. We acquired the stock pursuant to the company's restructuring. In the U.S. cable sector, our positions in Century Cable Holdings LLC and Charter Communications Operating LLC were additive to performance. The Adelphia securities rallied to slightly above par value after Adelphia sold its cable companies to Comcast Corporation and Time Warner Inc. At Charter Communications, a recent refinancing worked to improve the company's liquidity and eliminate short-term debt, prompting our bank loan holding to advance. In the services sector, our positions in Anthony Crane Rental LP and The Shaw Group, Inc. contributed positively to Fund performance. The value of the Anthony Crane term loan has risen as the company prepares to exit bankruptcy with a more favorable capital structure. Anthony Crane was further supported by improvements in the commercial construction industry, which has displayed signs of renewed vigor. The Shaw Group, an engineering and consulting firm, announced better-than-expected earnings. This boosted the share price of the company's stock, which we had received from the restructuring of IT Group, a company that Shaw Group acquired in 2002. How would you characterize the portfolio's position at the close of the period? At the end of the period, the Trust was composed of 164 issuers spread among 26 industries. The Trust was underweight versus its composite benchmark in securities rated Ba or better and credits rated Caa or below, and there were overweight positions in B-rated and unrated securities. The portfolio's overall credit quality effectively is positioned more to the center of the leveraged loan market. Joseph P. Matteo Vice President and Portfolio Manager September 20, 2005 MERRILL LYNCH SENIOR FLOATING RATE FUND, INC. AUGUST 31, 2005 Disclosure of Expenses Shareholders of this Fund may incur the following charges: (a) expenses related to transactions, including sales charges, redemption fees and exchange fees; and (b) operating expenses, including advisory fees, distribution fees including 12(b)-1 fees, and other Fund expenses. The following example (which is based on a hypothetical investment of $1,000 invested on March 1, 2005 and held through August 31, 2005) is intended to assist shareholders both in calculating expenses based on an investment in the Fund and in comparing these expenses with similar costs of investing in other mutual funds. The first table below provides information about actual account values and actual expenses. In order to estimate the expenses a shareholder paid during the period covered by this report, shareholders can divide their account value by $1,000 and then multiply the result by the number in the first line under the heading entitled "Expenses Paid During the Period." The second table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses. In order to assist shareholders in comparing the ongoing expenses of investing in this Fund and other funds, compare the 5% hypothetical example with the 5% hypothetical examples that appear in other funds' shareholder reports. The expenses shown in the table are intended to highlight shareholders ongoing costs only and do not reflect any transactional expenses, such as sales charges, redemption fees or exchange fees. Therefore, the second table is useful in comparing ongoing expenses only, and will not help shareholders determine the relative total expenses of owning different funds. If these transactional expenses were included, shareholder expenses would have been higher. Expenses Paid Beginning Ending During the Period* Account Value Account Value March 1, 2005 March 1, August 31, to August 31, 2005 2005 2005 Actual Merrill Lynch Senior Floating Rate Fund, Inc. $1,000 $1,021.90 $7.08 Hypothetical (5% annual return before expenses)** Merrill Lynch Senior Floating Rate Fund, Inc. $1,000 $1,018.20 $7.07 * Expenses are equal to the annualized expense ratio of 1.39%, multiplied by the average account value over the period, multiplied by 184/365 (to reflect the one-half year period shown). Because the Fund is a feeder fund, the expense table example reflects the expenses of both the feeder fund and the master fund in which it invests. ** Hypothetical 5% annual return before expenses is calculated by pro-rating the number of days in the most recent fiscal half-year divided by 365.

MERRILL LYNCH SENIOR FLOATING RATE FUND, INC. AUGUST 31, 2005 Notes to Financial Statements Merrill Lynch Senior Floating Rate Fund, Inc. 1. Significant Accounting Policies: Merrill Lynch Senior Floating Rate Fund, Inc. (the "Fund") is registered under the Investment Company Act of 1940, as amended, as a continuously offered, non- diversified, closed-end management investment company. The Fund seeks to achieve its investment objective by investing all of its assets in the Master Senior Floating Rate Trust (the "Trust"), which has the same investment objective and strategies as the Fund. The value of the Fund's investment in the Trust reflects the Fund's proportionate interest in the net assets of the Trust. The performance of the Fund is directly affected by the performance of the Trust. The financial statements of the Trust, including the Schedule of Investments, are included elsewhere in this report and should be read in conjunction with the Fund's financial statements. The Fund's financial statements are prepared in conformity with U.S. generally accepted accounting principles, which may require the use of management accruals and estimates. Actual results may differ from these estimates. The percentage of the Trust owned by the Fund at August 31, 2005 was 65.6%. The following is a summary of significant accounting policies followed by the Fund. (a) Valuation of investments--The Fund records its investment in the Trust at fair value. Valuation of securities held by the Trust is discussed in Note 1(b) of the Trust's Notes to Financial Statements, which are included elsewhere in this report. (b) Investment income and expenses--The Fund records daily its proportionate share of the Trust's income, expenses and realized and unrealized gains and losses. In addition, the Fund accrues its own expenses. (c) Income taxes--It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable income to its shareholders. Therefore, no federal income tax provision is required. (d) Prepaid registration fees--Prepaid registration fees are charged to expense as the related shares are issued. (e) Dividends and distributions--Dividends from net investment income are declared daily and paid monthly. Distributions of capital gains are recorded on the ex-dividend dates. (f) Investment transactions--Investment transactions in the Trust are accounted for on a trade date basis. (g) Reclassifications--U.S. generally accepted accounting principles require that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. Accordingly, during the current year, $3,278,446 has been reclassified between paid in capital in excess of par and accumulated realized capital losses and $228 has been reclassified between accumulated realized capital losses and undistributed net investment income as a result of permanent differences attributable to the expiration of capital loss carryforwards and the allocation of differences in the accrual of income on securities in default. These reclassifications have no effect on net assets or net asset values per share. 2. Transactions with Affiliates: The Fund has entered into an Administration Agreement with Fund Asset Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc. ("PSI"), an indirect, wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is the limited partner.

MERRILL LYNCH SENIOR FLOATING RATE FUND, INC. AUGUST 31, 2005 Report of Independent Registered Public Accounting Firm Merrill Lynch Senior Floating Rate Fund, Inc. To the Shareholders and Board of Directors of Merrill Lynch Senior Floating Rate Fund, Inc.: We have audited the accompanying statement of assets and liabilities of Merrill Lynch Senior Floating Rate Fund, Inc. (the "Fund"), as of August 31, 2005, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation.

See Notes to Financial Statements. MERRILL LYNCH SENIOR FLOATING RATE FUND, INC. AUGUST 31, 2005 Notes to Financial Statements Master Senior Floating Rate Trust 1. Significant Accounting Policies: Master Senior Floating Rate Trust (the "Trust") is registered under the Investment Company Act of 1940, as amended, and is organized as a Delaware statutory trust. The Declaration of Trust permits the Trustees to issue nontransferable interests in the Trust, subject to certain limitations. The Trust's financial statements are prepared in conformity with U.S. generally accepted accounting principles, which may require the use of management accruals and estimates. Actual results may differ from these estimates. The following is a summary of significant accounting policies followed by the Trust. (a) Loan participation interests--The Trust primarily invests in senior secured floating rate loan interests ("Loan Interests") with collateral having a market value, at the time of acquisition by the Trust, which Trust management believes equals or exceeds the principal amount of the Loan Interests. The Trust may invest up to 20% of its total assets in loans made on an unsecured basis. Because agents, banks and intermediate participants from whom the Trust purchases the loan interest are primarily financial institutions, the Trust's investment in Loan Interests at August 31, 2005 could be considered to be concentrated in the industry group consisting of financial institutions. (b) Valuation of investments--Loan Interests are valued in accordance with guidelines established by the Board of Trustees. Loan Interests are valued at the mean between the last available bid and asked prices from one or more brokers or dealers as obtained from Loan Pricing Corporation. For the limited number of Loan Interests for which no reliable price quotes are available, such Loan Interests will be valued by Loan Pricing Corporation through the use of pricing matrixes to determine valuations. If the pricing service does not provide a value for the Loan Interests, the Investment Adviser will value the Loan Interests at fair value, which is intended to approximate market value. Securities that are held by the Trust that are traded on stock exchanges or the Nasdaq National Market are valued at the last sale price or official close price on the exchange on which such securities are traded, as of the close of business on the day the securities are being valued or, lacking any sales, at the last available bid price for long positions, and at the last available asked price for short positions. In cases where securities are traded on more than one exchange, the securities are valued on the exchange designated as the primary market by or under the authority of the Board of Trustees of the Trust. Long positions in securities traded in the over-the-counter ("OTC") market, Nasdaq Small Cap or Bulletin Board are valued at the last available bid price or yield equivalent obtained from one or more dealers or pricing services approved by the Board of Trustees of the Trust. Short positions in securities traded in the OTC market are valued at the last available asked price. Portfolio securities that are traded both in the OTC market and on a stock exchange are valued according to the broadest and most representative market. When the Trust writes an option, the amount of the premium received is recorded on the books of the Trust as an asset and an equivalent liability. The amount of the liability is subsequently valued to reflect the current market value of the option written, based on the last sale price in the case of exchange-traded options or, in the case of options traded in the OTC market, the last asked price. Options purchased by the Trust are valued at their last sale price in the case of exchange-traded options or, in the case of options traded in the OTC market, the last bid price. Swap agreements are valued based upon quoted fair valuations received daily by the Trust from a pricing service or counterparty. Other investments, including futures contracts and related options, are stated at market value. Obligations with remaining maturities of 60 days or less are valued at amortized cost unless the Investment Adviser believes that this method no longer produces fair valuations. Repurchase agreements will be valued at cost plus accrued interest. The Trust employs certain pricing services to provide securities prices for the Trust. Securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith by or under the direction of the Board of Trustees of the Trust, including valuations furnished by the pricing services retained by the Trust, which may use a matrix system for valuations. The procedures of a pricing service and its valuations are reviewed by the officers of the Trust under the general supervision of the Board of Trustees. Such valuations and procedures will be reviewed periodically by the Board of Trustees. MERRILL LYNCH SENIOR FLOATING RATE FUND, INC. AUGUST 31, 2005 Notes to Financial Statements (continued) Master Senior Floating Rate Trust Generally, trading in foreign securities, as well as U.S. government securities and money market instruments, is substantially completed each day at various times prior to the close of business on the New York Stock Exchange ("NYSE"). The values of such securities used in computing the net assets of the Trust are determined as of such times. Foreign currency exchange rates also are generally determined prior to the close of business on the NYSE. Occasionally, events affecting the values of such securities and such exchange rates may occur between the times at which they are determined and the close of business on the NYSE that may not be reflected in the computation of the Trust's net assets. If events (for example, a company announcement, market volatility or a natural disaster) occur during such periods that are expected to materially affect the value of such securities, those securities may be valued at their fair value as determined in good faith by the Board of Trustees or by the Investment Adviser using a pricing service and/or procedures approved by the Board of Trustees. (c) Derivative financial instruments--The Trust may engage in various portfolio investment strategies both to increase the return of the Trust and to hedge, or protect, its exposure to interest rate movements and movements in the securities markets. Losses may arise due to changes in the value of the contract or if the counterparty does not perform under the contract. * Swaps--The Trust may enter into swap agreements, which are over-the-counter contracts in which the Trust and counterparty agree to make periodic net payments on a specified notional amount. The net payments can be made for a set period of time or may be triggered by a pre-determined credit event. The net periodic payments may be based on a fixed or variable interest rate; the change in market value of a specified security, basket of securities, or index; or the return generated by a security. These periodic payments received or made by the Trust are recorded in the accompanying Statement of Operations as realized gains and losses, respectively. Gains or losses are also realized upon termination of the swap agreements. Swaps are marked-to-market daily and changes in value are recorded as unrealized appreciation (depreciation). Risks include changes in the returns of the underlying instruments, failure of the counterparties to perform under the contracts' terms and the possible lack of liquidity with respect to the swap agreements. (d) Income taxes--The Trust is classified as a partnership for federal income tax purposes. As such, each investor in the Trust is treated as owner of its proportionate share of the net assets, income, expenses and realized and unrealized gains and losses of the Trust. Therefore, no federal income tax provision is required. It is intended that the Trust's assets will be managed so an investor in the Trust can satisfy the requirements of subchapter M of the Internal Revenue Code. (e) Security transactions and investment income--Security transactions are recorded on the dates the transactions are entered into (the trade dates). Realized gains and losses on security transactions are determined on the identified cost basis. Dividend income is recorded on the ex-dividend dates. Interest income is recognized on the accrual basis. The Trust amortizes all premiums and discounts on debt securities. (f) Securities lending--The Trust may lend securities to financial institutions that provide cash or securities issued or guaranteed by the U.S. government as collateral, which will be maintained at all times in an amount equal to at least 100% of the current market value of the loaned securities. The market value of the loaned securities is determined at the close of business of the Trust and any additional required collateral is delivered to the Trust on the next business day. Where the Trust receives securities as collateral for the loaned securities, it receives a fee from the borrower. The Trust typically receives the income on the loaned securities, but does not receive the income on the collateral. Where the Trust receives cash collateral, it may invest such collateral and retain the amount earned on such investment, net of any amount rebated to the borrower. Loans of securities are terminable at any time and the borrower, after notice, is required to return borrowed securities within five business days. The Trust may pay reasonable finder's, lending agent, administrative and custodial fees in connection with its loans. In the event that the borrower defaults on its obligation to return borrowed securities because of insolvency or for any other reason, the Trust could experience delays and costs in gaining access to the collateral. The Trust also could suffer a loss where the value of the collateral falls below the market value of the borrowed securities, in the event of borrower default or in the event of losses on investments made with cash collateral. (g) Custodian bank--The Trust recorded an amount payable to the custodian bank reflecting an overnight overdraft, which resulted from management estimates of available cash. MERRILL LYNCH SENIOR FLOATING RATE FUND, INC. AUGUST 31, 2005 Notes to Financial Statements (concluded) Master Senior Floating Rate Trust 2. Investment Advisory Agreement and Transactions with Affiliates: The Trust has entered into an Investment Advisory Agreement with Fund Asset Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc. ("PSI"), an indirect, wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is the limited partner. FAM is responsible for the management of the Trust's portfolio and provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of the Trust. For such services, the Trust pays a monthly fee at an annual rate of .95% of the average daily value of the Trust's net assets. The Trust has received an exemptive order from the Securities and Exchange Commission permitting it to lend portfolio securities to Merrill Lynch, Pierce, Fenner & Smith Incorporated, an affiliate of FAM, or its affiliates. Pursuant to that order, the Trust also has retained Merrill Lynch Investment Managers, LLC ("MLIM, LLC"), an affiliate of FAM, as the securities lending agent for a fee based on a share of the returns on investment of cash collateral. MLIM, LLC may, on behalf of the Trust, invest cash collateral received by the Trust for such loans, among other things, in a private investment company managed by MLIM, LLC or in registered money market funds advised by FAM or its affiliates. For the year ended August 31, 2005, the Trust reimbursed FAM $23,163 for certain accounting services. Certain officers and/or trustees of the Trust are officers and/or directors of FAM, PSI, ML & Co., and/or MLIM, LLC. 3. Investments: Purchases and sales (including paydowns) of investments, excluding short-term securities, for the year ended August 31, 2005 were $572,350,150 and $475,745,113, respectively. 4. Unfunded Loan Interests: As of August 31, 2005, the Trust had unfunded loan commitments of approximately $30,177,000 which would be extended at the option of the borrower, pursuant to the following loan agreements: Unfunded Commitment Borrower (in Thousands) Key Energy Services TLB $3,000 Maguire Properties, LP $3,800 NFIL Holdings Corp. $5,000 Pinnacle Entertainment, Inc. $1,060 Trump Entertainment Resorts Holdings LP Revolving Line of Credit $4,283 Trump Entertainment Resorts Holdings LP Term Loan B-1 $2,500 Vanguard Health Systems, Inc. $1,000 Vought Aircraft Industries, Inc. $6,000 Wyndham International $3,534 5. Short-Term Borrowings: The Trust, along with certain other funds managed by FAM and its affiliates, is a party to a $500,000,000 credit agreement with a group of lenders, which expires November 2005. The Trust may borrow under the credit agreement to fund shareholder redemptions and for other lawful purposes other than for leverage. The Trust may borrow up to the maximum amount allowable under the Trust's current prospectus and statement of additional information, subject to various other legal, regulatory or contractual limits. The Trust pays a commitment fee of .07% per annum based on the Trust's pro rata share of the unused portion of the credit agreement. Amounts borrowed under the credit agreement bear interest at a rate equal to, at each Trust's election, the federal funds rate plus .50% or a base rate as defined in the credit agreement. The Trust did not borrow under the credit agreement during the year ended August 31, 2005. MERRILL LYNCH SENIOR FLOATING RATE FUND, INC.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Trust is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of August 31, 2005, by correspondence with the custodian and financial intermediaries; where replies were not received from financial intermediaries, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Master Senior Floating Rate Trust as of August 31, 2005, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and its financial highlights for the respective periods then ended, in conformity with U.S. generally accepted accounting principles.

Audit, audit-related and tax compliance services provided to the registrant on an annual basis require specific pre-approval by the Committee. The Committee also must approve other non-audit services provided to the registrant and those non-audit services provided to the registrant's affiliated service providers that relate directly to the operations and the financial reporting of the registrant. Certain of these non-audit services that the Committee believes are a) consistent with the SEC's auditor independence rules and b) routine and recurring services that will not impair the independence of the independent accountants may be approved by the Committee without consideration on a specific case-by-case basis ("general pre-approval"). However, such services will only be deemed pre-approved provided that any individual project does not exceed $5,000 attributable to the registrant or $50,000 for all of the registrants the Committee oversees. Any proposed services exceeding the pre-approved cost levels will require specific pre- approval by the Committee, as will any other services not subject to general pre-approval (e.g., unanticipated but permissible services). The Committee is informed of each service approved subject to general pre-approval at the next regularly scheduled in-person board meeting.

Forbes Cynthia A. Montgomery Jean Margo Reid Kevin A. Ryan (retired as of December 31, 2004) Roscoe S. Suddarth Richard R. West Edward D. Zinbarg Item 6 - Schedule of Investments - Not Applicable Item 7 - Disclosure of Proxy Voting Policies and Procedures for Closed-End Management Investment Companies - Proxy Voting Policies and Procedures Each Fund's Board of Directors/Trustees has delegated to Merrill Lynch Investment Managers, L.P. and/or Fund Asset Management, L.P. (the "Investment Adviser") authority to vote all proxies relating to the Fund's portfolio securities. The Investment Adviser has adopted policies and procedures ("Proxy Voting Procedures") with respect to the voting of proxies related to the portfolio securities held in the account of one or more of its clients, including a Fund. Pursuant to these Proxy Voting Procedures, the Investment Adviser's primary objective when voting proxies is to make proxy voting decisions solely in the best interests of each Fund and its shareholders, and to act in a manner that the Investment Adviser believes is most likely to enhance the economic value of the securities held by the Fund. The Proxy Voting Procedures are designed to ensure that the Investment Adviser considers the interests of its clients, including the Funds, and not the interests of the Investment Adviser, when voting proxies and that real (or perceived) material conflicts that may arise between the Investment Adviser's interest and those of the Investment Adviser's clients are properly addressed and resolved. In order to implement the Proxy Voting Procedures, the Investment Adviser has formed a Proxy Voting Committee (the "Committee"). The Committee is comprised of the Investment Adviser's Chief Investment Officer (the "CIO"), one or more other senior investment professionals appointed by the CIO, portfolio managers and investment analysts appointed by the CIO and any other personnel the CIO deems appropriate. The Committee will also include two non- voting representatives from the Investment Adviser's Legal department appointed by the Investment Adviser's General Counsel. The Committee's membership shall be limited to full-time employees of the Investment Adviser. No person with any investment banking, trading, retail brokerage or research responsibilities for the Investment Adviser's affiliates may serve as a member of the Committee or participate in its decision making (except to the extent such person is asked by the Committee to present information to the Committee, on the same basis as other interested knowledgeable parties not affiliated with the Investment Adviser might be asked to do so). The Committee determines how to vote the proxies of all clients, including a Fund, that have delegated proxy voting authority to the Investment Adviser and seeks to ensure that all votes are consistent with the best interests of those clients and are free from unwarranted and inappropriate influences. The Committee establishes general proxy voting policies for the Investment Adviser and is responsible for determining how those policies are applied to specific proxy votes, in light of each issuer's unique structure, management, strategic options and, in certain circumstances, probable economic and other anticipated consequences of alternate actions. In so doing, the Committee may determine to vote a particular proxy in a manner contrary to its generally stated policies. In addition, the Committee will be responsible for ensuring that all reporting and recordkeeping requirements related to proxy voting are fulfilled. The Committee may determine that the subject matter of a recurring proxy issue is not suitable for general voting policies and requires a case-by-case determination. In such cases, the Committee may elect not to adopt a specific voting policy applicable to that issue. The Investment Adviser believes that certain proxy voting issues require investment analysis - such as approval of mergers and other significant corporate transactions - akin to investment decisions, and are, therefore, not suitable for general guidelines. The Committee may elect to adopt a common position for the Investment Adviser on certain proxy votes that are akin to investment decisions, or determine to permit the portfolio manager to make individual decisions on how best to maximize economic value for a Fund (similar to normal buy/sell investment decisions made by such portfolio managers). While it is expected that the Investment Adviser will generally seek to vote proxies over which the Investment Adviser exercises voting authority in a uniform manner for all the Investment Adviser's clients, the Committee, in conjunction with a Fund's portfolio manager, may determine that the Fund's specific circumstances require that its proxies be voted differently. To assist the Investment Adviser in voting proxies, the Committee has retained Institutional Shareholder Services ("ISS"). ISS is an independent adviser that specializes in providing a variety of fiduciary-level proxy-related services to institutional investment managers, plan sponsors, custodians, consultants, and other institutional investors. The services provided to the Investment Adviser by ISS include in-depth research, voting recommendations (although the Investment Adviser is not obligated to follow such recommendations), vote execution, and recordkeeping. ISS will also assist the Fund in fulfilling its reporting and recordkeeping obligations under the Investment Company Act. The Investment Adviser's Proxy Voting Procedures also address special circumstances that can arise in connection with proxy voting. For instance, under the Proxy Voting Procedures, the Investment Adviser generally will not seek to vote proxies related to portfolio securities that are on loan, although it may do so under certain circumstances. In addition, the Investment Adviser will vote proxies related to securities of foreign issuers only on a best efforts basis and may elect not to vote at all in certain countries where the Committee determines that the costs associated with voting generally outweigh the benefits. The Committee may at any time override these general policies if it determines that such action is in the best interests of a Fund. From time to time, the Investment Adviser may be required to vote proxies in respect of an issuer where an affiliate of the Investment Adviser (each, an "Affiliate"), or a money management or other client of the Investment Adviser (each, a "Client") is involved. The Proxy Voting Procedures and the Investment Adviser's adherence to those procedures are designed to address such conflicts of interest. The Committee intends to strictly adhere to the Proxy Voting Procedures in all proxy matters, including matters involving Affiliates and Clients. If, however, an issue representing a non-routine matter that is material to an Affiliate or a widely known Client is involved such that the Committee does not reasonably believe it is able to follow its guidelines (or if the particular proxy matter is not addressed by the guidelines) and vote impartially, the Committee may, in its discretion for the purposes of ensuring that an independent determination is reached, retain an independent fiduciary to advise the Committee on how to vote or to cast votes on behalf of the Investment Adviser's clients. In the event that the Committee determines not to retain an independent fiduciary, or it does not follow the advice of such an independent fiduciary, the powers of the Committee shall pass to a subcommittee, appointed by the CIO (with advice from the Secretary of the Committee), consisting solely of Committee members selected by the CIO. The CIO shall appoint to the subcommittee, where appropriate, only persons whose job responsibilities do not include contact with the Client and whose job evaluations would not be affected by the Investment Adviser's relationship with the Client (or failure to retain such relationship). The subcommittee shall determine whether and how to vote all proxies on behalf of the Investment Adviser's clients or, if the proxy matter is, in their judgment, akin to an investment decision, to defer to the applicable portfolio managers, provided that, if the subcommittee determines to alter the Investment Adviser's normal voting guidelines or, on matters where the Investment Adviser's policy is case-by-case, does not follow the voting recommendation of any proxy voting service or other independent fiduciary that may be retained to provide research or advice to the Investment Adviser on that matter, no proxies relating to the Client may be voted unless the Secretary, or in the Secretary's absence, the Assistant Secretary of the Committee concurs that the subcommittee's determination is consistent with the Investment Adviser's fiduciary duties In addition to the general principles outlined above, the Investment Adviser has adopted voting guidelines with respect to certain recurring proxy issues that are not expected to involve unusual circumstances. These policies are guidelines only, and the Investment Adviser may elect to vote differently from the recommendation set forth in a voting guideline if the Committee determines that it is in a Fund's best interest to do so. In addition, the guidelines may be reviewed at any time upon the request of a Committee member and may be amended or deleted upon the vote of a majority of Committee members present at a Committee meeting at which there is a quorum. The Investment Adviser has adopted specific voting guidelines with respect to the following proxy issues: * Proposals related to the composition of the Board of Directors of issuers other than investment companies. As a general matter, the Committee believes that a company's Board of Directors (rather than shareholders) is most likely to have access to important, nonpublic information regarding a company's business and prospects, and is therefore best-positioned to set corporate policy and oversee management. The Committee, therefore, believes that the foundation of good corporate governance is the election of qualified, independent corporate directors who are likely to diligently represent the interests of shareholders and oversee management of the corporation in a manner that will seek to maximize shareholder value over time. In individual cases, the Committee may look at a nominee's history of representing shareholder interests as a director of other companies or other factors, to the extent the Committee deems relevant. * Proposals related to the selection of an issuer's independent auditors. As a general matter, the Committee believes that corporate auditors have a responsibility to represent the interests of shareholders and provide an independent view on the propriety of financial reporting decisions of corporate management. While the Committee will generally defer to a corporation's choice of auditor, in individual cases, the Committee may look at an auditors' history of representing shareholder interests as auditor of other companies, to the extent the Committee deems relevant. * Proposals related to management compensation and employee benefits. As a general matter, the Committee favors disclosure of an issuer's compensation and benefit policies and opposes excessive compensation, but believes that compensation matters are normally best determined by an issuer's board of directors, rather than shareholders. Proposals to "micro-manage" an issuer's compensation practices or to set arbitrary restrictions on compensation or benefits will, therefore, generally not be supported. * Proposals related to requests, principally from management, for approval of amendments that would alter an issuer's capital structure. As a general matter, the Committee will support requests that enhance the rights of common shareholders and oppose requests that appear to be unreasonably dilutive. * Proposals related to requests for approval of amendments to an issuer's charter or by-laws. As a general matter, the Committee opposes poison pill provisions. * Routine proposals related to requests regarding the formalities of corporate meetings. * Proposals related to proxy issues associated solely with holdings of investment company shares. As with other types of companies, the Committee believes that a fund's Board of Directors (rather than its shareholders) is best-positioned to set fund policy and oversee management. However, the Committee opposes granting Boards of Directors authority over certain matters, such as changes to a fund's investment objective, that the Investment Company Act envisions will be approved directly by shareholders. * Proposals related to limiting corporate conduct in some manner that relates to the shareholder's environmental or social concerns. The Committee generally believes that annual shareholder meetings are inappropriate forums for discussion of larger social issues, and opposes shareholder resolutions "micromanaging" corporate conduct or requesting release of information that would not help a shareholder evaluate an investment in the corporation as an economic matter. While the Committee is generally supportive of proposals to require corporate disclosure of matters that seem relevant and material to the economic interests of shareholders, the Committee is generally not supportive of proposals to require disclosure of corporate matters for other purposes.
