MERRILL LYNCH SENIOR FLOATING RATE FUND, INC., AUGUST 31, 2004 A Letter From the President Dear Shareholder In recent months, the Federal Reserve Board (the Fed) has taken center stage as it shifts away from its long-accommodative monetary stance. The Fed raised the Federal Funds rate 75 basis points (.75%) in three separate moves since June, bringing the target short-term interest rate to 1.75% - still low by historical standards. The Fed has been deliberate in telegraphing its intention to take a "measured" approach to interest rate increases in order to avoid upsetting the economy or the financial markets, while still leaving room to move more aggressively if inflation and economic growth accelerate more than anticipated. The forward curve currently projects further increases in short-term interest rates before year- end. In addition to the Fed policy change, the financial markets recently have had to grapple with a tense geopolitical environment, higher oil prices and the worry and anticipation that accompanies a presidential election. The transition to higher rates can cause concern among equity and fixed income investors alike. For bond investors, rising interest rates means the value of older issues declines because they bear the former lower interest rates. In addition, increasing inflation erodes the purchasing power of fixed income securities. Nevertheless, for the six-month and 12-month periods ended August 31, 2004, fixed income markets provided positive results. For example, the Lehman Brothers Aggregate Bond Index returned +1.15% and +6.13%; the Credit Suisse First Boston High Yield Index returned +3.42% and +14.68%; and the Citigroup Mortgage Index returned +1.79% and +6.07% for the six-month and 12-month periods, respectively. As always, our investment professionals are closely monitoring the markets, the economy and the overall environment in an effort to make well-informed decisions for the portfolios they manage. Our goal is to provide shareholders with competitive returns, while always keeping one eye on managing the unavoidable risk inherent in investing. We thank you for trusting Merrill Lynch Investment Managers with your investment assets, and we look forward to serving you in the months and years ahead. Sincerely, (Terry K. Glenn) Terry K. Glenn President and Director/Trustee MERRILL LYNCH SENIOR FLOATING RATE FUND, INC., AUGUST 31, 2004 A Discussion With Your Fund's Portfolio Manager The Fund's total return for the year surpassed that of its benchmark in a market environment largely conducive to higher net asset values and decreased yields. Describe market conditions during the past year. The leveraged loan market, as measured by the Credit Suisse First Boston (CSFB) Leveraged Loan Index, returned +7.05% for the one-year period ended August 31, 2004. Over the past 12 months, the market's largest monthly return was 1.04% in January 2004. Only two months of the past 12 posted returns exceeding 1%, whereas the 12 months ended August 2003 included six months with returns surpassing 1%. Since the beginning of 2004, flows into the leveraged loan market have outpaced new-issue volume by $1.5 billion, exacerbating an existing supply/demand imbalance. This trend has gained steam, with inflows during July at year high levels. Further crowding the leveraged loan space is participation by hedge funds and collateralized debt obligations. Through August 31, 2004, $100 billion of new issuance has come to the institutional market year to date, representing an annual record and an increase of 69% versus the same period a year ago. However, the available pool of loans has grown by only $19 billion; thus, 81% of the activity has been refinancings. The supply/demand imbalance has prompted decreased spreads, transaction upsizing, smaller allocations and the near elimination of up-front fees in the primary markets. The new-issue spread for institutional loans rated BB/BB- was 213 basis points (2.13%) in August 2004, compared to 295 basis points in September 2003. For loans rated B/B+, the spread was 291 basis points in August 2004 versus 350 basis points in September 2003. The torrid demand also has bid up prices in the secondary market. The net effect of these trends has been higher net asset values but decreased yields, although increases in LIBOR (London InterBank Offer Rate) have helped mitigate some of the decline in margin. Adding to investor demand for the leveraged loan asset class has been a steady decline in the default rate. Through the first eight months of 2004, there were just four loan defaults totaling $911 million. This compared to 11 defaults totaling $2.7 billion during the same period in 2003. The floating rate nature of leveraged loans has been a desirable characteristic for investors seeking to add a defensive position to their portfolios in anticipation of rising interest rates. How did the Fund perform during the fiscal year in light of the existing market conditions? For the 12-month period ended August 31, 2004, the Common Stock of Merrill Lynch Senior Floating Rate Fund, Inc. had a net annualized yield of 3.30%, based on a year-end per share net asset value of $8.91 and $0.294 per share income dividends. Over the same period, the total investment return on the Fund's Common Stock was +9.73%, based on a change in per share net asset value from $8.40 to $8.91, and assuming reinvestment of $0.300 per share ordinary income dividends. The low point for the Fund's net asset value during the period was $8.40, which occurred at the start of the fiscal year. The net asset value increased by $0.50, or 5.95% (excluding the effects of income), given positive total returns in all 12 months of the period. This ultimately allowed the Fund to provide a total return exceeding the +7.05% return of the CSFB Leveraged Loan Index for the year. Although the three-month LIBOR rose by 66 basis points during the year - from 1.14% at August 31, 2003, to 1.80% at August 31, 2004 - the Fund's 12-month average daily yield (based on daily net asset value) declined 132 basis points, from 4.81% last year to 3.49% at August 31, 2004. This trend illustrates the massive spread adjustment underway in the leveraged loan market over the past year. For the six-month period ended August 31, 2004, the total investment return on the Fund's Common Stock was +2.33%, based on a change in per share net asset value from $8.84 to $8.91, and assuming reinvestment of $0.135 per share income dividends. MERRILL LYNCH SENIOR FLOATING RATE FUND, INC., AUGUST 31, 2004 Drivers of the Fund's return for the year were the U.S. cable sector, led by Century Cable Holdings LLC, and the utilities sector, led by Mission Energy Holding Company. A notable story in the U.S. cable sector centered on Adelphia Cable, of which Century Cable is a subsidiary. The company declared bankruptcy in June 2002 and is preparing to auction assets in October 2004. The bank loans have been current throughout the process and rallied significantly over the past year. We expect par payment on our investment within six months. Mission Energy ran into credit difficulties during the summer of 2002. This year, after announcing an asset sale program to repay its debt, Mission rallied to above par. In August, the company repaid its Term Loan A and, subsequently, its Term Loan B rallied to par plus pricing. During the year, we liquidated a position in bankrupt aluminum company Ormet. Our position started the year marked in the mid 20s and rallied to the low 40s in line with an improving aluminum market. At that point, we negotiated a block trade of our position. What changes were made to the portfolio during the fiscal year? From a sector perspective, we continued to put greatest emphasis on those industries with strong asset values and stable cash-flow characteristics. Cable television remains the sector with the highest concentration, followed by utilities, chemicals, wireless, services, manufacturing, leisure, diversified media and telecommunications. Merrill Lynch Senior Floating Rate Fund, Inc. is a feeder of the Master Senior Floating Rate Trust. Since August 2003, the Trust reduced exposure to names rated Baa and Ba, increased exposure to single B names, reduced exposure to Caa1 or below names, and increased exposure to "not rated" names (allocations exclude the Trust's cash position). All of the changes were in line with trends experienced by the market, as represented by the CSFB Leveraged Loan Index. How would you characterize the Trust's position at the close of the period? As of August 31, 2004, Master Senior Floating Rate Trust was composed of 137 issuers in 28 industries. This compares to 155 issuers spread among 39 industries a year ago. Compared to the CSFB Leveraged Loan Index as of the same date, the Trust was overweight in names rated above Baa1 (23.5% versus 0% for the Index). This was solely due to the Trust's cash position. The Trust was underweight names rated Baa and Ba (28.9% versus 48.8% for the Index), overweight single B (35.7% versus 33.4%), overweight Caa or below (5.6% versus 3.1%) and underweight not rated names (6.1% versus 14.8%). Excluding its cash position, the Trust's composition at period-end was 0% above Baa1, 30.1% Baa and Ba, 50% single B, 2.7% Caa1 or below, and 16.3% not rated. Looking ahead, the trend of small allocations and tighter spreads appears likely to continue. The movement in interest rates is one of the larger variables affecting the leveraged loan market. The more protracted the timetable of increases, the larger the flows to the leveraged loan market, which could negatively affect market technicals. Nevertheless, we expect continued growth in the U.S. economy to bode well for default rates over the remainder of this year and into the next. We will aim to put the Fund's excess cash to work, while remaining focused on achieving an appropriate balance of risk and return. To that end, we will continue to rigorously review potential investments for solid credit fundamentals. Joseph P. Matteo Vice President and Portfolio Manager September 23, 2004 MERRILL LYNCH SENIOR FLOATING RATE FUND, INC., AUGUST 31, 2004 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, 2004 and held through August 31, 2004) 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, 2004 March 1, 2004 August 31, 2004 to August 31, 2004 Actual Merrill Lynch Senior Floating Rate Fund, Inc. $1,000 $1,023.30 $7.39 Hypothetical (5% annual return before expenses)** Merrill Lynch Senior Floating Rate Fund, Inc. $1,000 $1,017.70 $7.37 * Expenses are equal to the annualized expense ratio of 1.45%, 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, 2004 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 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, 2004 was 71.9%. 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 1b 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 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, $1,471,065 has been reclassified between paid-in capital in excess of par and accumulated realized capital losses on investments, $357,435 has been reclassified between paid-in capital in excess of par and undistributed net investment income and $93,847 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 asset or net asset value 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. The Fund pays a monthly fee at an annual rate of ..25% of the Fund's average daily net assets for the performance of administrative services (other than investment advice and related portfolio activities) necessary for the operation of the Fund. Financial Data Services, Inc. ("FDS"), a wholly-owned subsidiary of ML & Co., is the Fund's transfer agent. For the year ended August 31, 2004, FAM Distributors, Inc.

(the "Fund"), as of August 31, 2004, 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. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. 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 Merrill Lynch Senior Floating Rate Fund, Inc. as of August 31, 2004, 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 each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles.

See Notes to Financial Statements. MERRILL LYNCH SENIOR FLOATING RATE FUND, INC., AUGUST 31, 2004 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 Corporate Loan. The Trust may invest up to 20% of its total assets in loans made on an unsecured basis. Because agent banks and intermediate participants from whom the Trust purchases the loan interest are primarily financial institutions, the Trust's investment in Corporate Loans at August 31, 2004 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 matrices 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 ask 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 ask 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 ask 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. The value of swaps, including interest rate swaps, caps and floors, will be determined by obtaining dealer quotations. 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 Trustees. MERRILL LYNCH SENIOR FLOATING RATE FUND, INC., AUGUST 31, 2004 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. (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 trans-actions 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 collects 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. MERRILL LYNCH SENIOR FLOATING RATE FUND, INC., AUGUST 31, 2004 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 ("MLPF&S"), 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, 2004, the Trust reimbursed FAM $19,670 for certain accounting services. Certain officers and/or trustees of the Trust are officers and/or directors of FAM, PSI, FDS, and/or ML & Co. 3. Investments: Purchases and sales of investments, excluding short-term securities, for the year ended August 31, 2004 were $599,252,611 and $721,190,900, respectively. 4. Unfunded Corporate Loans: As of August 31, 2004, the Trust had unfunded loan commitments of approximately $21,078,000, which would be extended at the option of the borrower, pursuant to the following loan agreements: Unfunded Commitment Borrower (in thousands) Anthony Crane Rental Holdings LP $4,500 Doane Pet Care Company $3,058 NFIL Holdings Inc. $4,925 SBA Senior Finance, Inc. $1,163 Saguaro Utility Group LP $7,432 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 Bank One, N.A. and certain other lenders. The Trust may borrow under the credit agreement to fund investors, withdrawals 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 ..09% 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 fund's election, the Federal Funds rate plus .50% or a base rate as determined by Bank One, N.A. On November 28, 2003, the credit agreement was renewed for one year under the same terms. The Trust did not borrow under the agreement during the year ended August 31, 2004. 6. Capital Transactions: Fair value of net assets contributions for the year ended August 31, 2003 reflect the conversion of Merrill Lynch Senior Floating Rate Fund, Inc. into a feeder fund of the Trust on February 10, 2003.

These financial statements and financial highlights are the responsibility of the Trust's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

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.

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 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.
