Semi-Annual Report August 31, 2004 Senior High Income Portfolio, Inc. seeks to provide shareholders with as high a level of current income as is consistent with its investment policies and prudent investment management by investing principally in senior debt obligations of companies, including corporate loans made by banks and other financial institutions and both privately placed and publicly offered corporate bonds and notes. The Fund invests primarily in debt obligations that are rated in the lower rating categories of the established rating services (Baa or lower by Moody's Investors Service, Inc. or BBB or lower by Standard & Poor's) or unrated debt investments of comparable quality. This report, including the financial information herein, is transmitted to shareholders of Senior High Income Portfolio, Inc. for their information. It is not a prospectus.

Senior High Income Portfolio, Inc. The Benefits and Risks of Leveraging Senior High Income Portfolio, Inc. (the "Fund") utilizes leverage through borrowings or issuance of short-term debt securities or shares of Preferred Stock. The concept of leveraging is based on the premise that the cost of assets to be obtained from leverage will be based on short-term interest rates, which normally will be lower than the income earned by the Fund on its longer-term portfolio investments. To the extent that the total assets of the Fund (including the assets obtained from leverage) are invested in higher- yielding portfolio investments, the Fund's Common Stock shareholders will be the beneficiaries of the incremental yield. Leverage creates risks for holders of Common Stock including the likelihood of greater net asset value and market price volatility. In addition, there is the risk that fluctuations in interest rates on borrowings (or in the dividend rates on any Preferred Stock, if the Fund were to issue the Preferred Stock) may reduce the Common Stock's yield and negatively impact its net asset value and market price. If the income derived from securities purchased with assets received from leverage exceeds the cost of leverage, the Fund's net income will be greater than if leverage had not been used. Conversely, if the income from the securities purchased is not sufficient to cover the cost of leverage, the Fund's net income will be less than if leverage had not been used, and therefore the amount available for distribution to Common Stock shareholders will be reduced.

SENIOR HIGH INCOME PORTFOLIO, 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 SENIOR HIGH INCOME PORTFOLIO, INC., AUGUST 31, 2004 A Discussion With Your Portfolio Manager The Portfolio provided positive returns for the period, outperforming its blended benchmark due to an overweight position in high yield bonds and our ample use of leverage. How did the Portfolio perform during the period in light of the existing market conditions? For the six-month period ended August 31, 2004, the Common Stock of Senior High Income Portfolio, Inc. had net annualized yields of 8.88% and 9.23%, based on a period-end per share net asset value of $6.10 and a per share market price of $5.87, respectively, and $0.273 per share income dividends. Over the same period, the total investment return on the Portfolio's Common Stock was +4.84%, based on a beginning and ending net asset value of $6.10, and assuming reinvestment of $0.276 per share ordinary income dividends. The Portfolio's benchmark, which is an equal blend of the Credit Suisse First Boston (CSFB) High Yield Index and the CSFB Leveraged Loan Index, returned +2.85% for the same period. For a description of the Portfolio's total investment return based on a change in the per share market value of the Portfolio's Common Stock (as measured by the trading price of the Portfolio's shares on the New York Stock Exchange), and assuming reinvestment of dividends, please refer to the Financial Highlights section of the Financial Statements included in this report. As a closed-end fund, the Portfolio's shares may trade in the secondary market at a premium or discount to the Portfolio's net asset value. As a result, total investment returns based on changes in the market value of the Portfolio's Common Stock can vary significantly from total investment returns based on changes in the Portfolio's net asset value. The rate of high yield bond issuance has kept pace with that of 2003, with high yield proceeds of $66 billion in the first half of 2004 versus $68 billion in the first half of 2003. As in 2003, this year's issuance has consisted primarily of refinancing activity (75%), as corporate treasurers capitalized on the relatively low interest rate environment. During this period, there was a troublesome trend whereby companies were issuing zero-coupon debt at the holding company to finance dividends to equity sponsors. This activity had a "double-barreled" impact on leverage - increasing debt while decreasing equity - and often stretched credit parameters beyond reasonable limits. However, the market eventually pushed back and we have seen this trend subside. Nevertheless, the high yield market's risk appetite has been steadily increasing. The percentage of transactions rated B or lower has risen from 45% in 2001 to 54% in 2002, 63% in 2003 and 68% in the first half of 2004. This trend may persist as the forecast default rate continues to decline. Moody's Investors Service is predicting a 2004 default rate of 2.3%, compared to 4.13% in 2003. Technicals in the leveraged bank loan market were similar to those of the high yield market. Refinancing accounted for 81% of bank loan issuance in the first half of 2004, while investor demand for bank loans soared. The resulting supply/demand imbalance prompted tighter spreads, smaller allocations and transaction upsizing. For example, the average spread on B-rated loans compressed from 350 basis points (3.5%) in September 2003 to 291 basis points in August 2004. What were the reasons for the Portfolio's outperformance of its benchmark? The Portfolio's outperformance was driven primarily by our overweight position in high yield bonds. We rebalanced the Portfolio toward fixed rate investments after the events of September 11, 2001, as the Federal Reserve Board (the Fed) cut the Federal Funds rate from 3.5% to 1.0% by June 2003. The interest rate cuts had dramatically reduced the yield on the LIBOR-based bank loan component of the portfolio. (LIBOR refers to the London Interbank Offer Rate. The three-month LIBOR is the base upon which nearly all our bank loans and floating rate notes are set.) Also contributing to the Portfolio's outperformance was our ample use of the permissible leverage lines. We use commercial paper-based borrowings for leverage up to 33% of the Portfolio's total assets. The average amount of Portfolio leverage during the six-month period was 27.8%. (For a complete discussion of the benefits and risk of leverage, refer to page 2 of this report to shareholders.) Top-performing portfolio holdings during the past six months included Mission Energy Holding Company, Highland Legacy Limited Co. and GEO Specialty Chemicals Inc. In Mission Energy, the Portfolio holds $6.5 million in bonds with a 13.5% coupon. The bonds, which are due on July 15, 2008, appreciated in price from 103 to 123 during the period. The company is selling a portfolio of international assets and has received much higher-than-expected bids. This has led to speculation that the company will tender for this issue somewhere in the high 120s range. SENIOR HIGH INCOME PORTFOLIO, INC., AUGUST 31, 2004 Regarding Highland Legacy, our $4 million investment in this collateralized debt obligation continued to rally during the period from 55 to 75. This price action reflects the favorable impact of the high yield rally on the portfolio's valuation. Our $3.6 million bond position in GEO appreciated from 30 to 50 during the period. GEO, which filed for bankruptcy in March 2004, has a portfolio of niche businesses that supply functional chemicals to the industrial water treatment, paints and coatings, construction and electronics markets. During the past several months, all of the market segments in which the company operated benefited from a strong U.S. economy. Investments that detracted from results during the period included Telewest Global, Inc., Advanced Accessory Systems and Calpine Corporation. Our $7.9 million bond position in Telewest, which was priced at 64.5 on March 1, 2004, was converted into equity through a U.K. court reorganization. Our August 31, 2004 equity value equates to a price of about 47 on the bond position. We suspect that this is due to technical pressures arising from bondholders liquidating their equity positions. Telewest management continues to make significant operating progress. The Portfolio's $7.5 million bond investment in automotive supplier Advanced Accessory Systems declined in price from 106 to 95 during the period. The company's prospects continue to be impaired by its higher steel costs and pricing concession demands from the original equipment manufacturers. The Portfolio owns $4 million in bank debt and $3 million in bonds of merchant power company Calpine. During the period, the prices of both securities were volatile, but ultimately declined about 10 points. Calpine's electrical generation capacity consists of gas turbines. The company continues to feel the impact of a low-spark spread environment (that is, high natural gas prices and soft wholesale electrical prices), coupled with the higher operating expenses associated with a larger plant fleet. As Calpine has now almost completed it expansion program, forward funding requirements will subside. In the meantime, we believe the company's liquidity is sufficient to see it through an eventual recovery in market prices. What changes were made to the Portfolio during the period? We continued to reposition the Portfolio during the period, shifting to an allocation of 60% fixed rate and 40% floating rate investments. This compared to a composition of 80% fixed rate and 20% floating rate last year. Given the robust demand for bank loans, allocations were usually a small percentage of our original order. To achieve our 60% fixed/40% floating rate target, we purchased $33 million in floating rate notes during the six-month period. We continue to believe that the downside risk associated with rising interest rates outweighs the benefits we may see from a bond rally. At period-end, the Fed had already initiated two interest rate hikes of 25 basis points. There was a third quarter-point increase in September, bringing the target short-term interest rate to 1.75%. This, and the prospect of additional interest rate hikes, served to raise the three-month LIBOR rate from 1.12% at August 31, 2003, to 1.80% at August 31, 2004. How would you characterize the Portfolio's position at the close of the period? We would characterize our position at period-end as defensive while still focused on maintaining the Portfolio's attractive yield. We also continue to be cautious and selective in adding new positions, and intend to maintain our use of leverage within a target range of 25%-30% of total assets. Kevin J.

SENIOR HIGH INCOME PORTFOLIO, INC., AUGUST 31, 2004 Notes to Financial Statements 1. Significant Accounting Policies: Senior High Income Portfolio, Inc. (the "Fund") is registered under the Investment Company Act of 1940, as amended, as a non- diversified, closed-end management investment company. 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. These unaudited financial statements reflect all adjustments, which are, in the opinion of management, necessary to present a fair statement of the results for the interim period. All such adjustments are of a normal, recurring nature. The Fund determines and makes available for publication the net asset value of its Common Stock on a daily basis. The Fund's Common Stock is listed on the New York Stock Exchange ("NYSE") under the symbol ARK. (a) Corporate debt obligations--The Fund invests principally in senior debt obligations of companies, including Corporate Loans made by banks and other financial institutions and both privately and publicly offered corporate bonds and notes. Because agents and intermediaries are primarily commercial banks or other financial institutions, the Fund's investment in Corporate Loans could be considered concentrated in financial institutions. (b) Valuation of investments--Corporate Loans are valued in accordance with guidelines established by the Fund's Board of Directors. Corporate Loans 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 Corporate Loans for which no reliable price quotes are available, such Corporate Loans 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 a Corporate Loan, the Investment Adviser will value the Corporate Loan at fair value, which is intended to approximate market value. Securities that are held by the Fund 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 Directors of the Fund. 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 Directors of the Fund. 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 Fund writes an option, the amount of the premium received is recorded on the books of the Fund 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 Fund 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 Fund employs certain pricing services to provide securities prices for the Fund. 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 Directors of the Fund, including valuations furnished by the pricing services retained by the Fund, which may use a matrix system for valuations. The procedures of a pricing service and its valuations are reviewed by the officers of the Fund under the general supervision of the Board of Directors. Such valuations and procedures will be reviewed periodically by the Board of Directors. SENIOR HIGH INCOME PORTFOLIO, INC., AUGUST 31, 2004 Notes to Financial Statements (continued) 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 NYSE. The values of such securities used in computing the net asset value of the Fund's shares 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 Fund's net asset value. 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 Directors or by the Investment Adviser using a pricing service and/or procedures approved by the Board of Directors. (c) Derivative financial instruments--The Fund may engage in various portfolio investment strategies both to increase the returns of the Fund 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. * Financial futures contracts--The Fund may purchase or sell financial futures contracts and options on such futures contracts for the purpose of hedging the market risk on existing securities or the intended purchase of securities. Futures contracts are contracts for delayed delivery of securities at a specific future date and at a specific price or yield. Upon entering into a contract, the Fund deposits and maintains as collateral such initial margin as required by the exchange on which the transaction is effected. Pursuant to the contract, the Fund agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in value of the contract. Such receipts or payments are known as variation margin and are recorded by the Fund as unrealized gains or losses. When the contract is closed, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. * Options--The Fund may write and purchase call and put options. When the Fund writes an option, an amount equal to the premium received by the Fund is reflected as an asset and an equivalent liability. The amount of the liability is subsequently marked-to- market to reflect the current market value of the option written. When a security is purchased or sold through an exercise of an option, the related premium paid (or received) is added to (or deducted from) the basis of the security acquired or deducted from (or added to) the proceeds of the security sold. When an option expires (or the Fund enters into a closing transaction), the Fund realizes a gain or loss on the option to the extent of the premiums received or paid (or gain or loss to the extent the cost of the closing transaction is less than or exceeds the premiums paid or received). Written and purchased options are non-income producing investments. * Swaps--The Fund may enter into swap agreements, which are OTC contracts in which the Fund and a 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--It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable income to its shareholders. Therefore, no federal income tax provision is required. (e) Security transactions and investment income--Security transactions are recorded on the dates the transactions are entered into (the trade dates). Realized gains and losses on security transactions are determined on the identified cost basis. Interest income is recognized on the accrual basis. The Fund amortizes all premiums and discounts on debt securities. (f) Dividends and distributions--Dividends from net investment income are declared and paid monthly. Distributions of capital gains are recorded on the ex-dividend dates. The Fund may at times pay out less than the entire amount of net investment income earned in any particular period and may at times pay out such accumulated undistributed income in other periods to permit the Fund to maintain a more stable level of dividends. SENIOR HIGH INCOME PORTFOLIO, INC., AUGUST 31, 2004 Notes to Financial Statements (continued) (g) Securities lending--The Fund 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 Fund and any additional required collateral is delivered to the Fund on the next business day. Where the Fund receives securities as collateral for the loaned securities, it collects a fee from the borrower. The Fund typically receives the income on the loaned securities but does not receive the income on the collateral. Where the Fund 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 Fund 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 Fund could experience delays and costs in gaining access to the collateral. The Fund 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. 2. Investment Advisory Agreement and Transactions with Affiliates: The Fund 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 Fund's portfolio and provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of the Fund. For such services, the Fund pays a monthly fee at an annual rate of .50% of the Fund's average weekly net assets plus the proceeds of any outstanding borrowings used for leverage. The Fund 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"), a subsidiary of ML & Co., or its affiliates. Pursuant to that order, the Fund 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 Fund, invest cash collateral received by the Fund 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 six months ended August 31, 2004, the Fund reimbursed FAM $3,586 for certain accounting services. In addition, MLPF&S received $1,250 in commissions on the execution of Portfolio security transactions for the Portfolio for the six months ended August 31, 2004. Certain officers and/or directors of the Fund are officers and/or directors of FAM, PSI, and/or ML & Co. 3. Investments: Purchases and sales of investments, excluding short-term securities, for the six months ended August 31, 2004 were $174,485,311 and $164,832,346, respectively. 4. Capital Share Transaction: The Fund is authorized to issue 200,000,000 shares of capital stock par value $.10, all of which are initially classified as Common Stock. The Board of Directors is authorized, however, to classify and reclassify any unissued shares of capital stock without approval of the holders of Common Stock. Shares issued and outstanding during the six months ended August 31, 2004 and for the year ended February 28, 2003 increased by 42,393 and 614,404, respectively, as a result of dividend reinvestment. 5. Unfunded Corporate Loans: As of August 31, 2004, the Fund had unfunded loan commitments of $1,343,590, which would be extended at the option of the borrower, pursuant to the following loan agreements: Unfunded Commitment Borrower (in thousands) SP Newsprint $967 SBA Communications $377 SENIOR HIGH INCOME PORTFOLIO, INC., AUGUST 31, 2004 Notes to Financial Statements (concluded) 6. Short-Term Borrowings: On May 26, 2004, the Fund renewed its $151,000,000 revolving credit and security agreement with Citibank, N.A. and other lenders (the "Lenders"). The Fund may borrow money through (i) a line of credit from certain Lenders at the Eurodollar rate plus .75%, or the highest of the Federal Funds rate plus .50%, a base rate as determined by Citibank, N.A. and the latest three-week moving average of secondary market morning offering rates in the U.S. for three-month certificates of deposit of major U.S. money market banks plus .50%, or (ii) the issuance of commercial paper notes by certain Lenders at rates of interest derived from the weighted average of the per annum rates paid or payable by such Lenders in respect of those commercial notes. As security for its obligations to the Lenders under the revolving credit and security agreement, the Fund has granted a security interest in substantially all of its assets to and in favor of the Lenders. The Fund also pays additional borrowing costs which includes a commitment fee for this facility at an annual rate of .10% and a program fee of .24% on the borrowings outstanding. For the six months ended August 31, 2004, the average amount borrowed was approximately $137,454,000 and the daily weighted average interest rate was 1.48%. 7. Capital Loss Carryforward: On February 29, 2004, the Fund had a capital loss carryforward of $151,440,900 of which $733,844 expires in 2005; $4,282,847 expires in 2007; $12,755,214 expires in 2008; $25,658,795 expires in 2009; $54,958,583 expires in 2010; $30,706,546 expires in 2011 and $22,345,071 expires in 2012. This amount will be available to offset like amounts on any future taxable gains. 8. Subsequent Event: The Portfolio paid an ordinary income dividend in the amount of $.045000 per share on September 30, 2004 to shareholders of record on September 14, 2004.
