Privacy. The Eaton Vance organization is committed to ensuring your financial privacy. Each of the financial institutions identified below has in effect the following policy ("Privacy Policy") with respect to nonpublic personal information about its customers:

•  Only such information received from you, through application forms or otherwise, and information about your Eaton Vance fund transactions will be collected. This may include information such as name, address, social security number, tax status, account balances and transactions.

•  None of such information about you (or former customers) will be disclosed to anyone, except as permitted by law (which includes disclosure to employees necessary to service your account). In the normal course of servicing a customer's account, Eaton Vance may share information with unaffiliated third parties that perform various required services such as transfer agents, custodians and broker/dealers.

•  Policies and procedures (including physical, electronic and procedural safeguards) are in place that are designed to protect the confidentiality of such information.

•  We reserve the right to change our Privacy Policy at any time upon proper notification to you. Customers may want to review our Policy periodically for changes by accessing the link on our homepage: www.eatonvance.com.

Our pledge of privacy applies to the following entities within the Eaton Vance organization: the Eaton Vance Family of Funds, Eaton Vance Management, Eaton Vance Investment Counsel, Boston Management and Research, and Eaton Vance Distributors, Inc.

In addition, our Privacy Policy only applies to those Eaton Vance customers who are individuals and who have a direct relationship with us. If a customer's account (i.e. fund shares) is held in the name of a third-party financial adviser/broker-dealer, it is likely that only such adviser's privacy policies apply to the customer. This notice supersedes all previously issued privacy disclosures.

For more information about Eaton Vance's Privacy Policy, please call 1-800-262-1122.

Delivery of Shareholder Documents. The Securities and Exchange Commission permits funds to deliver only one copy of shareholder documents, including prospectuses, proxy statements and shareholder reports, to fund investors with multiple accounts at the same residential or post office box address. This practice is often called "householding" and it helps eliminate duplicate mailings to shareholders.

Eaton Vance, or your financial adviser, may household the mailing of your documents indefinitely unless you instruct Eaton Vance, or your financial adviser, otherwise.

If you would prefer that your Eaton Vance documents not be householded, please contact Eaton Vance at 1-800-262-1122, or contact your financial adviser.

Your instructions that householding not apply to delivery of your Eaton Vance documents will be effective within 30 days of receipt by Eaton Vance or your financial adviser.

Portfolio Holdings. Each Eaton Vance Fund and Portfolio will file a schedule of its portfolio holdings on Form N-Q with the SEC for the first and third quarters of each fiscal year. The Form N-Q will be available on the Eaton Vance website www.eatonvance.com, by calling Eaton Vance at 1-800-262-1122 or in the EDGAR database on the SEC's website at www.sec.gov. Form N-Q may also be reviewed and copied at the SEC's public reference room in Washington, D.C. (call 1-800-732-0330 for information on the operation of the public reference room).

Proxy Voting. From time to time, funds are required to vote proxies related to the securities held by the funds. The Eaton Vance Funds or their underlying Portfolios (if applicable) vote proxies according to a set of policies and procedures approved by the Funds' and Portfolios' Boards. You may obtain a description of these policies and procedures and information on how the Funds or Portfolios voted proxies relating to Portfolio securities during the most recent 12 month period ended June 30, without charge, upon request, by calling 1-800-262-1122. This description is also available on the SEC's website at www.sec.gov.

Eaton Vance Senior Floating-Rate Trust as of April 30, 2005

INVESTMENT UPDATE

The Trust

Performance for the Past Six Months

•Based on its April 2005 monthly dividend of $0.096 and a closing share price of $19.18, Eaton Vance Senior Floating-Rate Trust, a closed-end fund traded on the New York Stock Exchange (The “Trust”) had a market yield of 6.01%.(1)

•Based on share price (traded on the New York Stock Exchange), the Trust had a total return of -0.82% for the six months ended April 30, 2005. That return was the result of a decrease in share price from $19.94 on October 31, 2004 to $19.18 on April 30, 2005 and the reinvestment of $0.586 in regular monthly dividends.

•Based on net asset value, the Trust had a total return of 2.30% for the six months ended April 30, 2005. That return was the result of a decrease in net asset value per share from $18.97 on October 31, 2004 to $18.82 on April 30, 2005, and the reinvestment of all distributions.

•For performance comparison, the S&P/LSTA Leveraged Loan Index, had a return of 2.19% for the six months ended April 30, 2005.(2)

The Trust’s Investments

•The Trust’s investment objective is to provide a high level of current income. The Trust may, as a secondary objective, also seek preservation of capital to the extent consistent with its primary goal of high current income. The Trust invests primarily in senior secured floating-rate loans. As a result, the Trust may be well-positioned to take advantage of a rise in short-term interest rates. The Trust also has the ability to invest in non-investment-grade, or high-yield, corporate bonds.

•The Trust’s portfolio of senior loans and other investments represented 363 borrowers and 37 industries as of April 30, 2005. The Trust’s average loan size was just 0.24% of net assets, and no industry constituted more than 11.0% of the Trust’s net assets. Health care, telecommunications, cable and satellite television, building and development (which includes companies that manage/own apartments, shopping malls and commercial office buildings, among others) and publishing were the Trust’s largest sector weightings.

•Due to relatively stable credit conditions and continuing strong technical factors, credit spreads in the loan market were at historical lows and prices remained above par during the six-month period. Late in the period, loan pricing eased in response to significant spread widening in the high-yield bond market. Once again, the loan market demonstrated lower volatility relative to the bond and equity markets.

•    No specific sectors significantly underperformed within the Trust’s Portfolio. At this point in the credit cycle, we currently expect to maintain a relatively high quality portfolio, especially given the heightened liquidity and general loosening of credit standards.

•Due to tight credit spreads in the high-yield bond market in the fall of 2004, the Fund lowered its exposure to high-yield bonds early in the six-month period. As a percentage of net assets/total investments, high-yield bonds were reduced from 17.1%/10.8% at October 31, 2004 to 13.7%/8.6% at April 30, 2005. This action reduced potential NAV volatility when high-yield spreads widened in the first quarter of 2005.

•At April 30, 2005, the Trust had leverage in the amount of approximately 38% of the Trust’s total assets. The Trust also employs leverage though the issuance of Auction Preferred Shares (“APS”).(3) Use of financial leverage creates an opportunity for increased income but, at the same time, creates special risks (including the likelihood of greater volatility of net asset value and market price of common shares). The cost of the Trust’s APS rises and falls with changes in short-term interest rates. Such increases in cost of the Trust’s APS may be offset by increased income from the Trust’s senior loan investments.

(1) The Trust’s market yield is calculated by dividing the most recent dividend per share by the share market price at the end of the period and annualizing the result.

(2) It is not possible to invest directly in an Index. The Index’s total return does not reflect the commissions or expenses that would have been incurred if an investor individually purchased or sold the securities represented in the Index.

(3) Performance results reflect the effect of leverage resulting from the Trust’s Auction Preferred Shares. In the event of a rise in long-term interest rates, the value of the Trust’s investment portfolio could decline, which would reduce the asset coverage for its Auction Preferred Shares.

Past performance is no guarantee of future results. Returns are historical and are calculated by determining the percentage change in net asset value or share price (as applicable) with all distributions reinvested. Investment return and principal value will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. Performance is for the stated time period only; due to market volatility, the Trust’s current performance may be lower or higher than the quoted return.

The views expressed in this report are those of the portfolio managers and are current only through the end of the period of the report as stated on the cover. These views are subject to change at any time based upon market or other conditions, and Eaton Vance disclaims any responsibility to update such views. These views may not be relied on as investment advice and, because investment decisions for an Eaton Vance fund are based on many factors, may not be relied on as an indication of trading intent on behalf of any Eaton Vance fund.

Shares of the Trust are not insured by the FDIC and are not deposits or other obligations of, or guaranteed by, any depository institution. Shares are subject to investment risks, including possible loss of principal invested.

⁽¹⁾  Senior floating-rate interests often require prepayments from excess cash flows or permit the borrower to repay at its election. The degree to which borrowers repay, whether as a contractual requirement or at their election, cannot be predicted with accuracy. As a result, the actual remaining maturity may be substantially less than the stated maturities shown. However, it is anticipated that the senior floating-rate interests will have an expected average life of approximately two to three years. The stated interest rate represents the weighted average interest rate of all contracts within the senior loan facility. Senior Loans typically have rates of interest which are redetermined either daily, monthly, quarterly or semi-annually by reference to a base lending rate, plus a premium. These base lending rates are primarily the London-Interbank Offered Rate ("LIBOR"), and secondarily the prime rate offered by one or more major United States banks (the "Prime Rate") and the certificate of deposit ("CD") rate or other base lending rates used by commercial lenders.

⁽²⁾  Unfunded loan commitments. See Note 1E for description.

⁽³⁾  Security valued at fair value using methods determined in good faith by or at the direction of the Trustees.

⁽⁴⁾  Defaulted security.

⁽⁵⁾  Security exempt from registration under Rule 144A of the Securities Act of 1933. These securities may be sold in transactions exempt from registration, normally to qualified institutional buyers. At April 30, 2005, the aggregate value of the securities is $32,730,407 or 5.2% of the net assets.

⁽⁶⁾  Non-income producing security.

1  Significant Accounting Policies

Eaton Vance Senior Floating-Rate Trust (the Trust) is registered under the Investment Company Act of 1940, as amended, as a closed-end management investment company. The Trust, which was organized as a Massachusetts business trust on August 5, 2003, seeks to provide a high level of current income. The Trust may, as a secondary objective, also seek preservation of capital to the extent consistent with its primary goal of high current income. The Trust pursues its objectives by investing primarily in senior, secured floating rate loans (Senior Loans). The following is a summary of significant accounting policies of the Trust. The policies are in conformity with accounting principles generally accepted in the United States of America.

AInvestment Valuation - Certain Senior Loans are deemed to be liquid because reliable market quotations are readily available for them. Liquid Senior Loans are valued on the basis of prices furnished by a pricing service. Other Senior Loans are valued at fair value by the Trust's investment adviser, Eaton Vance Management (EVM), under procedures approved by the Trustees. In connection with determining the fair value of a Senior Loan, the investment adviser makes an assessment of the likelihood that the borrower will make a full repayment of the Senior Loan. The primary factors considered by the investment adviser when making this assessment are (i) the creditworthiness of the borrower, (ii) the value of the collateral backing the Senior Loan, and (iii) the priority of the Senior Loan versus other creditors of the borrower. If, based on its assessment, the investment adviser believes there is a reasonable likelihood that the borrower will make a full repayment of the Senior Loan, the investment adviser will determine the fair value of the Senior Loan using a matrix pricing approach that considers the yield on the Senior Loan relative to yields on other loan interests issued by companies of comparable credit quality. If, based on its assessment, the investment adviser believes there is not a reasonable likelihood that the borrower will make a full repayment of the Senior Loan, the investment adviser will determine the fair value of the Senior Loan using analyses that include, but are not limited to (i) a comparison of the value of the borrower's outstanding equity and debt to that of comparable public companies; (ii) a discounted cash flow analysis; or (iii) when the investment adviser believes it is likely that a borrower will be liquidated or sold, an analysis of the terms of such liquidation or sale. In certain cases, the investment adviser will use a combination of analytical methods to determine fair value, such as when only a portion of a borrower's assets are likely to be sold. In conducting its assessment and analyses for purposes of determining fair value of a Senior Loan, the investment adviser will use its discretion and judgment in considering and appraising such factors, data and information and the relative weight to be given thereto as it deems relevant, including without limitation, some or all of the following: (i) the fundamental characteristics of and fundamental analytical data relating to the Senior Loan, including the cost, size, current interest rate, maturity and base lending rate of the Senior Loan, the terms and conditions of the Senior Loan and any related agreements, and the position of the Senior Loan in the Borrower's debt structure; (ii) the nature, adequacy and value of the collateral securing the Senior Loan, including the Trust's rights, remedies and interests with respect to the collateral; (iii) the creditworthiness of the Borrower, based on an evaluation of, among other things, its financial condition, financial statements and information about the Borrower's business, cash flows, capital structure and future prospects; (iv) information relating to the market for the Senior Loan, including price quotations for and trading in the Senior Loan and interests in similar Senior Loans and the market environment and investor attitudes towards the Senior Loan and interests in similar Senior Loans; (v) the experience, reputation, stability and financial condition of the agent and any intermediate participants in the Senior Loan; and (vi) general economic and market conditions affecting the fair value of the Senior Loan. Other portfolio securities (other than short-term obligations, but including listed issues) may be valued on the basis of prices furnished by one or more pricing services which determine prices for normal, institutional-size trading units of such securities which may use market information, transactions for comparable securities and various relationships between securities which are generally recognized by institutional traders. In certain circumstances, portfolio securities will be valued at the last sale price on the exchange that is the primary market for such securities, or the average of the last quoted bid price and asked price for those securities for which the over-the-counter market is the primary market or for listed securities in which there were no sales during the day. Marketable securities listed in the NASDAQ National Market System are valued at the NASDAQ official closing price. The value of swaps will be based on dealer quotations. Short-term obligations which mature in 60 days or less, are valued at amortized cost, if their original term to maturity when acquired by the Trust was 60 days or less or are valued at amortized cost using their value on the 61st day prior to maturity, if their original term to maturity when acquired by the Trust was more than 60 days, unless in each case this is determined not to represent fair value. OTC options are valued at the mean between bid and asked price provided by dealers. Financial futures contracts listed on commodity exchanges and

26

Eaton Vance Senior Floating-Rate Trust as of April 30, 2005

NOTES TO FINANCIAL STATEMENTS (Unaudited)CONT'D

exchange traded options are valued at closing settlement prices. Repurchase agreements are valued at cost plus accrued interest. Other portfolio securities for which there are no quotations or valuations are valued at fair value using methods determined in good faith by or at the direction of the Trustees.

B  Income - Interest income from Senior Loans is recorded on the accrual basis at the then-current interest rate, while all other interest income is determined on the basis of interest accrued, adjusted for amortization of premium or accretion of discount. Dividend income is recorded on the ex-dividend date for dividends received in cash and/or securities.

C  Federal Taxes - The Trust's policy is to comply with the provisions of the Internal Revenue Code applicable to regulated investment companies and to distribute to shareholders each year all of its taxable income, including any net realized gain on investments. Accordingly, no provision for federal income or excise tax is necessary. At October 31, 2004, the Trust, for federal income tax purposes, had a capital loss carryover of $5,860,075 which will reduce the Trust's taxable income arising from future net realized gains on investments, if any, to the extent permitted by the Internal Revenue Code, and thus will reduce the amount of the distributions to shareholders which would otherwise be necessary to relieve the Trust of any liability for federal income or excise tax. Such capital loss carryover will expire on October 31, 2012.

D  Investment Transactions - Investment transactions are recorded on a trade date basis. Realized gains and losses from such transactions are determined using the specific identification method. Securities purchased or sold on a when-issued or delayed delivery basis may be settled a month or more after the transaction date. The securities so purchased are subject to market fluctuations during this period. To the extent that when-issued or delayed delivery purchases are outstanding, the trust instructs the custodian to segregate assets in a separate account, with a current value at least equal to the amount of its purchase commitments.

E  Unfunded Loan Commitments - The Trust may enter into certain credit agreements all or a portion of which may be unfunded. The Trust is obligated to fund these loan commitments at the borrower's discretion. These commitments are disclosed in the accompanying Portfolio of Investments.

F  Offering Costs - Costs incurred by the Trust in connection with the offering of the common shares and preferred shares were recorded as a reduction of capital paid in excess of par applicable to common shares.

G  Expense Reduction - Investors Bank & Trust Company (IBT) serves as custodian of the Trust. Pursuant to the custodian agreement, IBT receives a fee reduced by credits which are determined based on the average daily cash balance the Trust maintains with IBT. All credit balances used to reduce the Trust's custodian fees are reported as a reduction of expenses on the Statement of Operations.

H  Written Options - Upon the writing of a call or a put option, an amount equal to the premium received by the Trust is included in the Statement of Assets and Liabilities as a liability. The amount of the liability is subsequently marked-to-market to reflect the current value of the option written in accordance with the Trust's policies on investment valuations discussed above. Premiums received from writing options which expire are treated as realized gains. Premiums received from writing options which are exercised or are closed are added to or offset against the proceeds or amount paid on the transaction to determine the realized gain or loss. If a put option is exercised, the premium reduces the cost basis of the securities purchased by the Trust. The Trust, as writer of an option, may have no control over whether the underlying securities may be sold (call) or purchased (put) and, as a result, bears the market risk of an unfavorable change in the price of the securities underlying the written option.

I  Purchased Options - Upon the purchase of a call or put option, the premium paid by the Trust is included in the Statement of Assets and Liabilities as an investment. The amount of the investment is subsequently marked-to-market to reflect the current market value of the option purchased, in accordance with the Trust's policies on investment valuations discussed above. If an option which the Trust has purchased expires on the stipulated expiration date, the Trust will realize a loss in the amount of the cost of the option. If the Trust enters into a closing sale transaction, the Trust will realize a gain or loss, depending on whether the sales proceeds from the closing sale transaction are greater or less than the cost of the option. If the Trust exercises a put option, it will realize a gain or loss from the sale of the underlying security, and the proceeds from such sale will be decreased by the premium originally paid. If the Trust exercises a call option, the cost of the security which the Trust purchases upon exercise will be increased by the premium originally paid.

Eaton Vance Senior Floating-Rate Trust as of April 30, 2005

NOTES TO FINANCIAL STATEMENTS (Unaudited)CONT'D

J  Financial Futures Contracts - Upon entering into a financial futures contract, the Trust is required to deposit an amount (initial margin) either in cash or securities equal to a certain percentage of the purchase price indicated in the financial futures contract. Subsequent payments are made or received by the Trust (margin maintenance) each day, dependent on the daily fluctuations in the value of the underlying securities, and are recorded for book purposes as unrealized gains or losses by the Trust.

If the Trust enters into a closing transaction, the Trust will realize, for book purposes, a gain or loss equal to the difference between the value of the financial futures contract to sell and the financial futures contract to buy. The Trust's investment in financial futures contracts is designed only to hedge against anticipated future changes in interest rates. Should interest rates move unexpectedly, the Trust may not achieve the anticipated benefits of the financial futures contracts and may realize a loss.

K  Reverse Repurchase Agreements - The Trust may enter into reverse repurchase agreements. Under such an agreement, the Trust temporarily transfers possession, but not ownership, of a security to a counterparty, in return for cash. At the same time, the Trust agrees to repurchase the security at an agreed-upon price and time in the future. The Trust may enter into reverse repurchase agreements for temporary purposes, such as to Trust withdrawals, or for use as hedging instruments where the underlying security is denominated in a foreign currency. As a form of leverage, reverse repurchase agreements may increase the risk of fluctuation in the market value of the Trust's assets or in its yield. Liabilities to counterparties under reverse repurchase agreements are recognized in the Statement of Assets and Liabilities at the same time at which cash is received by the Trust. The securities underlying such agreements continue to be treated as owned by the Trust and remain in the Portfolio of Investments. Interest charged on amounts borrowed by the Trust under reverse repurchase agreements is accrued daily.

L  Total Return Swaps - The Trust may enter into swap agreements to hedge against fluctuations in securities prices, interest rates or market conditions; to change the duration of the overall portfolio; to mitigate default risk; or for other risk management purposes. Pursuant to these agreements, the Trust makes monthly payments at a rate equal to a predetermined spread to the one-month LIBOR. In exchange, the Trust receives payments based on the rate of return of a benchmark industry index. During the term of the outstanding swap agreement, changes in the underlying value of the swap are recorded as unrealized gains and losses. Payments received or made at the end of the measurement period are recorded as realized gains and losses. The value of the swap is determined by changes in the relationship between the rate of interest and the benchmark industry index. The Trust is exposed to credit loss in the event of non-performance by the swap counterparty. However, the Trust does not anticipate non-performance by the counterparty. Risk may also arise from the unanticipated movements in value of interest rates or the index.

M  Credit Default Swaps - The Trust may enter into credit default swap contracts for risk management purposes, including diversification. When the Trust is the buyer of a credit default swap contract, the Trust is entitled to receive the par (or other agreed-upon) value of a referenced debt obligation from the counterparty to the contract in the event of a default by a third party, such as a U.S. or foreign corporate issuer, on the debt obligation. In return, the Trust would pay the counterparty a periodic stream of payments over the term of the contract provided that no event of default has occurred. If no default occurs, the Trust would have spent the stream of payments and received no benefit from the contract. When the Trust is the seller of a credit default swap contract, it receives the stream of payments, but is obligated to pay the par amount of the referenced debt obligation ("national amount of the swap") upon default of the referenced debt obligation. As the seller, the Trust would effectively add leverage to its portfolio because, in addition to its total net assets, the Trust would be subject to investment exposure on the notional amount of the swap. The Trust will segregate assets in the form of cash and cash equivalents in an amount equal to the aggregate market value of the credit default swaps of which it is the seller, marked to market on a daily basis. These transactions involve certain risks, including the risk that the seller may be unable to fulfill the transaction.

N  Use of Estimates - The preparation of the financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of income and expense during the reporting period. Actual results could differ from those estimates.

O  Indemnifications - Under the Trust's organizational documents, its officers and Trustees may be indemnified against certain liabilities and expenses arising out of the performance of their duties to the Trust, and

28

Eaton Vance Senior Floating-Rate Trust as of April 30, 2005

NOTES TO FINANCIAL STATEMENTS (Unaudited)CONT'D

shareholders are indemnified against personal liability for obligations of the Trust. Additionally, in the normal course of business, the Trust enters into agreements with service providers that may contain indemnification clauses. The Trust's maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Trust that have not yet occurred.

P  Other - Investment transactions are accounted for on the date the securities are purchased or sold. Realized gains and losses are computed based on the specific identification of securities sold.

Q  Interim Financial Statements - The interim financial statements relating to April 30, 2005 and for the six months then ended have not been audited by an Independent Registered Public Accounting Firm, but in the opinion of the Trust's management reflect all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of the financial statements.

2  Auction Preferred Shares

The Trust issued 3,940 shares of Auction Preferred Shares (APS) Series A, 3,940 shares of Auction Preferred Shares (APS) Series B, 3,940 shares of Auction Preferred Shares (APS) Series C, and 3,940 shares of Auction Preferred Shares (APS) Series D on January 26, 2004 in a public offering. The underwriting discount and other offering costs were recorded as a reduction of the capital of the common shares. Dividends on the APS, which accrue daily, are cumulative at a rate which was established at the offering of the APS and have been reset every 28 days thereafter by an auction. Dividend rates ranged from 2.194% to 3.240.% for Series A shares, 2.00% to 3.10% for Series B shares, 2.05% to 3.07% for Series C shares, and 2.11% to 3.75% for Series D shares.

The APS are redeemable at the option of the Trust, at a redemption price equal to $25,000 per share, plus accumulated and unpaid dividends on any dividend payment date. The APS are also subject to mandatory redemption at a redemption price equal to $25,000 per share, plus accumulated and unpaid dividends, if the Trust is in default for an extended period on its asset maintenance requirements with respect to the APS. If the dividends on the APS shall remain unpaid in an amount equal to two full years' dividends, the holders of the APS as a class have the right to elect a majority of the Board of Trustees. In general, the holders of the APS and the common shares have equal voting rights of one vote per share, except that the holders of the APS, as a separate class, have the right to elect at least two members of the Board of Trustees. The APS have a liquidation preference of $25,000 per share, plus accumulated and unpaid dividends.

The Trust is required to maintain certain asset coverage with respect to the APS as defined in the Trust's By-Laws and the Investment Company Act of 1940. The Trust pays an annual fee equivalent to 0.25% of the APS liquidation value for the remarketing efforts associated with the preferred auctions.

3  Distribution to Shareholders

The Trust intends to make monthly distributions of net investment income, after payment of any dividends on any outstanding APS. In addition, at least annually, the Trust intends to distribute net capital gain, if any. Distributions are recorded on the ex-dividend date. Distributions to preferred shareholders are recorded daily and are payable at the end of each dividend period. Each dividend payment period for the Auction Preferred Shares is generally twenty-eight days. The applicable dividend rate for the Auction Preferred Shares on April 30, 2005 was 3.24%, 3.05%, 3.07%, and 3.75%, for Series A, Series B, Series C, and Series D Shares, respectively. For the six months ended April 30, 2005, the Trust paid dividends to Auction Preferred shareholders amounting to $1,247,341, $1,247,039, $1,243,093 and $1,284,248 for Series A, Series B, Series C, and Series D Shares, respectively, representing an average APS dividend rate for such period of 2.596%, 2.566%, 2.591%, and 2.648%, respectively.

The Trust distinguishes between distributions on a tax basis and a financial reporting basis. Accounting principals generally accepted in the United States of America require that only distributions in excess of tax basis earnings and profits be reported in the financial statements as a return of capital. Permanent differences between book and tax accounting relating to distributions are reclassified to paid in capital. These differences relate primarily to the method for amortizing premiums.

4  Investment Adviser Fee and Other Transactions with Affiliates

The investment adviser fee, computed at an annual rate of 0.75% of the average daily gross assets of the Trust, was earned by Eaton Vance Management (EVM), as compensation for management and investment advisory services rendered to the Trust. For the six months ended April 30, 2005, the fee was equivalent to 0.75% (annualized) of the Trust's average daily gross assets for such period and amounted to $3,826,953.

In addition, the Adviser has contractually agreed to reimburse the Trust for fees and other expenses in the amount of 0.20% of the average daily gross assets of the Trust for the first five full years of the Trust's operations, 0.15% of average weekly gross assets in year 6, 0.10% in year 7 and 0.05% in year 8. For the six months ended

29

Eaton Vance Senior Floating-Rate Trust as of April 30, 2005

NOTES TO FINANCIAL STATEMENTS (Unaudited)CONT'D

April 30, 2005 the Adviser waived $1,019,652 of its advisory fee.

Certain officers and Trustees of the Trust are officers of the above organization.

5  Purchases and Sales of Investments

Purchases and sales of investments, other than short-term obligations and including paydowns, aggregated $390,663,235, and $359,517,425 respectively, for the six months ended April 30, 2005.

6  Common Shares of Beneficial Interest

The Agreement and Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional $0.01 par value common shares of beneficial interest. Transactions in common shares were as follows:

	Six Months Ended April 30, 2005 (Unaudited)		Year Ended October 31, 2004(1)
Sales		-		33,255,000
Issued to shareholders electing to receive payments of distributions in Fund shares		84,520		148,970
Net increase		84,520		33,403,970

⁽¹⁾For the period from the start of business, November 28, 2003, to October 31, 2004.

7  Federal Income Tax Basis of Unrealized Appreciation (Depreciation)

The cost and unrealized appreciation (depreciation) in value of investments owned by the Trust at April 30, 2005, as computed on a federal income tax basis, were as follows:

Aggregate Cost	$	993,896,454
Gross unrealized appreciation	$	8,329,553
Gross unrealized depreciation		(5,538,935	)
Net unrealized appreciation	$	2,790,618

8  Financial Instruments

The Trust may trade in financial instruments with off-balance sheet risk in the normal course of its investing activities to assist in managing exposure to various market risks. These financial instruments include written options and financial futures contracts and may involve, to a varying degree, elements of risk in excess of the amounts recognized for financial statement purposes. The notional or contractual amounts of these instruments represent the investment the Trust has in particular classes of financial instruments and does not necessarily represent the amounts potentially subject to risk. The measurement of the risks associated with these instruments is meaningful only when all related and offsetting transactions are considered.

DIVIDEND REINVESTMENT PLAN

The Trust offers a dividend reinvestment plan (the Plan) pursuant to which shareholders may elect to have dividends and capital gains distributions reinvested in common shares (the Shares) of the Trust. You may elect to participate in the Plan by completing the Dividend Reinvestment Plan Application Form. If you do not participate, you will receive all distributions in cash paid by check mailed directly to you by PFPC Inc. as dividend paying agent. On the distribution payment date, if the net asset value per Share is equal to or less than the market price per Share plus estimated brokerage commissions then new Shares will be issued. The number of Shares shall be determined by the greater of the net asset value per Share or 95% of the market price. Otherwise, Shares generally will be purchased on the open market by the Plan Agent. Distributions subject to income tax (if any) are taxable whether or not shares are reinvested.

If your shares are in the name of a brokerage firm, bank, or other nominee, you can ask the firm or nominee to participate in the Plan on your behalf. If the nominee does not offer the Plan, you will need to request that your shares be re-registered in your name with the Trust's transfer agent, PFPC, Inc. or you will not be able to participate.

The Plan Agent's service fee for handling distributions will be paid by the Trust. Each participant will be charged their pro rata share of brokerage commissions on all open-market purchases.

Plan participants may withdraw from the Plan at any time by writing to the Plan Agent at the address noted on the following page. If you withdraw, you will receive shares in your name for all Shares credited to your account under the Plan. If a participant elects by written notice to the Plan Agent to have the Plan Agent sell part or all of his or her Shares and remit the proceeds, the Plan Agent is authorized to deduct a $5.00 fee plus brokerage commissions from the proceeds.

If you wish to participate in the Plan and your shares are held in your own name, you may complete the form on the following page and deliver it to the Plan Agent.

Any inquires regarding the Plan can be directed to the Plan Agent, PFPC, Inc., at 1-800-331-1710.

BOARD OF TRUSTEES' ANNUAL APPROVAL OF THE INVESTMENT ADVISORY AGREEMENT

The investment advisory agreement between Eaton Vance Senior Floating-Rate Trust (the Trust) and the investment adviser, Eaton Vance Management ("Eaton Vance"), provides that the advisory agreement will continue in effect from year to year so long as its continuance is approved at least annually (i) by a vote of a majority of the noninterested Trustees of the Trust cast in person at a meeting called for the purpose of voting on such approval and (ii) by the Trustees of the Trust or by vote of a majority of the outstanding interests of the Trust.

In considering the annual approval of the investment advisory agreement between the Trust and the investment adviser, the Special Committee of the Board of Trustees considered information that had been provided throughout the year at regular Board meetings, as well as information furnished for a series of meetings held in February and March in preparation for a Board meeting held on March 21, 2005 to specifically consider the renewal of the investment advisory agreement. Such information included, among other things, the following:

•  An independent report comparing the advisory fees of the Trust with those of comparable funds;

•  An independent report comparing the expense ratio of the Trust to those of comparable funds;

•  Information regarding Trust investment performance (including on a risk-adjusted basis) in comparison to relevant peer groups of funds and appropriate indices;

•  The economic outlook and the general investment outlook in relevant investment markets;

•  Eaton Vance's results and financial condition and the overall organization of the investment adviser;

•  The procedures and processes used to determine the fair value of Trust assets including in particular the valuation of senior loan portfolios and actions taken to monitor and test the effectiveness of such procedures and processes;

•  Eaton Vance's management of the relationship with the custodian, subcustodians and fund accountants;

•  The resources devoted to compliance efforts undertaken by Eaton Vance on behalf of the funds it manages and the record of compliance with the investment policies and restrictions and with policies on personal securities transactions;

•  The quality, nature, cost and character of the administrative and other non-investment management services provided by Eaton Vance and its affiliates; and

•  The terms of the advisory agreement and the reasonableness and appropriateness of the particular fee paid by the Trust for the services described therein.

The Special Committee also considered the investment adviser's portfolio management capabilities, including information relating to the education, experience, and number of investment professionals and other personnel who provide services under the investment advisory agreement. Specifically, the Special Committee considered the investment adviser's experience in managing senior loan portfolios. The Special Committee noted the experience of the 26 bank loan investment professionals and other personnel who would provide services under the investment advisory agreement, including four portfolio managers and 15 analysts. Many of these portfolio managers and analysts have previous experience working for commercial banks and other lending institutions. The Special Committee also took into account the time and attention to be devoted by senior management to the Trust and the other funds in the complex. The Special Committee evaluated the level of skill required to manage the Trust and concluded that the human resources available at the investment adviser were appropriate to fulfill its duties on behalf of the Trust.

In its review of comparative information with respect to the Trust's investment performance (including on a risk-adjusted basis), the Special Committee noted the Trust's limited operating history and concluded that it was appropriate to allow time to fully evaluate the Trust's performance record. With respect to its review of investment advisory fees, the Special Committee concluded that the fees paid by the Trust are within the range of those paid by comparable funds within the mutual fund industry. In reviewing the information regarding the expense ratio of the Trust, the Special Committee concluded that the Trust's expense ratio is within a range that is competitive with comparable funds.

In addition to the factors mentioned above, the Special Committee reviewed the level of the investment adviser's profits in providing investment management and administration services for the Trust and for all Eaton Vance funds as a group. The Special Committee noted in particular that the Trust benefits from a contractual waiver of advisory fees and other expenses effective during the first five years of the Trust's operations. In addition, the Special Committee considered the fiduciary duty assumed by the investment adviser in connection with the services rendered to the Trust and the business reputation of the investment adviser and its financial resources.

BOARD OF TRUSTEES' ANNUAL APPROVAL OF THE INVESTMENT ADVISORY AGREEMENT CONT'D

The Trustees concluded that in light of the services rendered, the profits realized by the investment adviser are not unreasonable. The Special Committee also considered the fact that the Trust is not continuously offered and concluded that, in light of the level of the investment adviser's profits with respect to the Trust, the implementation of breakpoints is not appropriate.

The Special Committee did not consider any single factor as controlling in determining whether or not to renew the investment advisory agreement. Nor are the items described herein all the matters considered by the Special Committee. In assessing the information provided by Eaton Vance and its affiliates, the Special Committee also took into consideration the benefits to shareholders of investing in a fund that is a part of a large family of funds which provides a large variety of shareholder services.

Based on its consideration of the foregoing factors and conclusions, and such other factors and conclusions as it deemed relevant, and assisted by independent counsel, the Special Committee concluded that the renewal of the investment advisory agreement, including the fee structure, is in the interests of shareholders.

Item 7. Disclosure of Proxy Voting Policies and Procedures for Closed-End Management Investment Companies

The Board of Trustees of the Trust has adopted a proxy voting policy and procedure (the “Fund Policy”), pursuant to which the Trustees have delegated proxy voting responsibility to the Fund’s investment adviser and adopted the investment adviser’s proxy voting policies and procedures (the “Policies”) which are described below.  The Trustees will review the Fund’s proxy voting records from time to time and will annually consider approving the Policies for the upcoming year.  In the event that a conflict of interest arises between the Fund’s shareholders and the investment adviser, the administrator, or any of their affiliates or any affiliate of the Fund, the investment adviser will generally refrain from voting the proxies related to the companies giving rise to such conflict until it consults with the Board’s Special Committee except as contemplated under the Fund Policy.  The Board’s Special Committee will instruct the investment adviser on the appropriate course of action.

The Policies are designed to promote accountability of a company’s management to its shareholders and to align the interests of management with those shareholders.  The investment adviser will generally support company management on proposals relating to environmental and social policy issues, on matters regarding the state of organization of the company and routine matters related to corporate administration which are not expected to have a significant economic impact on the company or its shareholders.  On all other matters, the investment adviser will review each matter on a case-by-case basis and reserves the right to deviate from the Policies’ guidelines when it believes the situation warrants such a deviation.  The Policies include voting guidelines for matters relating to, among other things, the election of directors, approval of independent auditors, executive compensation, corporate structure and anti-takeover defenses.  The investment adviser may abstain from voting from time to time where it determines that the costs associated with voting a proxy outweighs the benefits derived from exercising the right to vote.

In addition, the investment adviser will monitor situations that may result in a conflict of interest between the Fund’s shareholders and the investment adviser, the administrator, or any of their affiliates or any affiliate of the Fund by maintaining a list of significant existing and prospective corporate clients.  The investment adviser’s personnel responsible for reviewing and voting proxies on behalf of the Fund will report any proxy received or expected to be received from a company included on that list to members of senior management of the investment adviser identified in the Policies. Such members of senior management will determine if a conflict exists.  If a conflict does exist, the investment adviser will seek instruction on how to vote from the Special Committee.

Information on how the Fund voted proxies relating to portfolio securities during the most recent 12 month period ended June 30 is available (1) without charge, upon request, by calling 1-800-262-1122, and (2) on the Securities and Exchange Commission’s website at http://www.sec.gov.

The Secretary shall retain copies of any shareholder recommendations which meet the foregoing requirements for a period of not more than 12 months following receipt. The Secretary shall have no obligation to acknowledge receipt of any shareholder recommendations.
