Schwertfeger Timothy R. Schwertfeger Chairman of the Board March 15, 2004 1 NUVEEN SENIOR INCOME FUND (NSL) Managers' PERSPECTIVE The Nuveen Senior Income Fund is managed by Gunther Stein and Lenny Mason of Symphony Asset Management, an indirect wholly owned subsidiary of Nuveen Investments, Inc. Gunther and Lenny have more than 25 years of combined investment management experience, much of it in evaluating and purchasing senior corporate loans and other high-yield debt. Here they review the prevailing economic conditions and performance of NSL for the period ended January 31, 2004. WHAT HAS BEEN THE GENERAL MARKET ENVIRONMENT FOR SENIOR CORPORATE LOANS OVER THE PERIOD ENDED JANUARY 31, 2004? During most of 2003, the senior loan market - sometimes called the leveraged loan market - was one of the strongest in ten years, as many companies benefited from signs of an economic recovery, improved access to capital and increased M&A lending activity. The CSFB Leveraged Loan Index1 returned 2.26% in the fourth quarter 2003, and 11.01% for the calendar year - the highest yearly return since 1993. The index posted a gain during each month of 2003 and the first month of 2004, and all industry sectors within the index had positive returns for the fourth quarter and full year 2003. The improving economy and company fundamentals helped the leveraged loan default rate in 2003 to decline to 2.3%, down from 4.5% in 2002. The syndicated leveraged loan market in 2003 had $166 billion of new issuance, up from $139 billion in 2002. Secondary market loan trading volume rose to $138 billion for 2003 from the previous record $117 billion in 2001. IN THIS ENVIRONMENT, HOW DID NSL PERFORM? For the twelve months ended January 31, 2004, the Nuveen Senior Income Fund produced a total return on net asset value (NAV) of 21.80%. Over the same period, the unmanaged, unleveraged CSFB Leverage Loan Index posted a total return of 10.67%. The Fund's total return performance for this period benefited from the strong overall performance of the leveraged loan market. As noted, rising prices were prevalent across nearly all industry sectors and ratings classes. The Fund's performance relative to the index also benefited from the Fund's use of leverage. Leveraging can add volatility to a Fund's net asset value and share price. However, this strategy also can provide opportunities for net asset value appreciation and enhanced income for common shareholders. 1 The CSFB Leveraged Loan Index consists of approximately $150 billion of tradable term loans with at least one year to maturity and rated BBB or lower. 2 The solid performance of several Fund holdings, including Washington Group, Conseco, Airgate, RCN, Centennial Cellular and Wyndham, also helped enhance overall total return performance during the period. WHAT STRATEGIES DID YOU EMPLOY IN MANAGING THE FUND? We continued to follow a value-oriented management strategy. That includes a review of a company's fundamentals, cash flow and asset quality. Since the new-issue market was robust over most of the period, we put an emphasis on purchasing high-quality new issue loans with what we judged to be strong asset coverage, solid business fundamentals and above average London Interbank Offered Rate (LIBOR) spreads. We also continued to evaluate the entire portfolio on a regular basis in an attempt to eliminate positions which we thought had the potential for credit problems, general weakness, limited upside potential or significant downside risk. 3 NUVEEN SENIOR INCOME FUND Performance OVERVIEW As of January 31, 2004 NSL PORTFOLIO STATISTICS ================================================== Share Price $9.32 -------------------------------------------------- Common Share Net Asset Value $8.29 -------------------------------------------------- Premium/Discount 12.42% -------------------------------------------------- Latest Dividend $.0430 -------------------------------------------------- Market Yield 5.54% -------------------------------------------------- Net Assets Applicable to Common Shares ($000) $246,715 -------------------------------------------------- % OF TOTAL TOP FIVE ISSUERS(1) INVESTMENTS ================================================== Conseco, Inc. 2.8% -------------------------------------------------- Fort James Corporation 2.5% -------------------------------------------------- D.R.

Because of these mandatory prepayment conditions and because there may be significant economic incentives for a Borrower to prepay, prepayments of Senior Loans in the Fund's portfolio may occur. As a result, the actual remaining maturity of Senior Loans held in the Fund's portfolio may be substantially less than the stated maturities shown. The Fund estimates that the actual average maturity of the Senior Loans held in its portfolio will be approximately 18-24 months. (1) All percentages shown in the Portfolio of Investments are based on net assets applicable to Common shares unless otherwise noted. (2) Senior Loans in which the Fund invests generally pay interest at rates which are periodically adjusted by reference to a base short-term, floating lending rate plus a premium. These base lending rates are generally (i) the lending rate offered by one or more major European banks, such as the London Inter-Bank Offered Rate ("LIBOR"), (ii) the prime rate offered by one or more major United States banks, or (iii) the certificate of deposit rate. Senior loans are generally considered to be restricted in that the Fund ordinarily is contractually obligated to receive approval from the Agent Bank and/or borrower prior to the disposition of a Senior Loan. (a) At or subsequent to January 31, 2004, this issue was non-income producing. (b) At or subsequent to January 31, 2004, this issue was under the protection of the federal bankruptcy court. (c) On January 1, 2002, CFRHoldings, Inc. (an entity formed by Nuveen for the benefit of the Nuveen Funds owning various interests in CanFibre of Riverside) took possession of the CanFibre of Riverside assets on behalf of the various Nuveen Funds. CFR Holdings, Inc. determined that a sale of the facility was in the best interest of shareholders and proceeded accordingly. (d) Anticipates future distributions from equities and warrants. (PIK) In lieu of cash payment, interest accrued on "Payment in Kind" security increases principal outstanding. + Borrowings payable as a percentage of total assets is 26.0%.

FINANCIAL STATEMENTS (Unaudited) 1. GENERAL INFORMATION AND SIGNIFICANT ACCOUNTING POLICIES Nuveen Senior Income Fund (the "Fund") is a non-diversified, closed-end management investment company registered under the Investment Company Act of 1940, as amended. The Fund's Common shares are listed on the New York Stock Exchange and trade under the ticker symbol "NSL". The Fund was organized as a Massachusetts business trust on August 13, 1999. The Fund seeks to provide a high level of current income by investing primarily in senior secured loans whose interest rates float or adjust periodically based on a benchmark interest rate index. The Fund seeks to increase the income available for distribution to Common shareholders by utilizing financial leverage. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements in accordance with accounting principles generally accepted in the United States. Investment Valuation The prices of senior loans, bonds and other securities in the Fund's investment portfolio are generally provided by one or more independent pricing services approved by the Fund's Board of Trustees. The pricing services typically value exchange-listed securities at the last sale price on that day; and value senior loans, bonds and other securities traded in the over-the-counter market at the mean of the highest bona fide bid and lowest bona fide ask prices when current quotations are readily available. The pricing services value senior loans, bonds and other securities for which current quotations are not readily available at fair value using a wide range of market data and other information and analysis, including the obligor's credit characteristics considered relevant by such pricing service to determine valuations. The Board of Trustees of the Fund has approved procedures which permit Nuveen Institutional Advisory Corp. (the "Adviser"), a wholly owned subsidiary of Nuveen Investments, Inc., to determine the fair value of securities for which the applicable pricing service or services is not providing a price, using market data and other factors such as the obligor's credit characteristics, and to override the price provided by the independent pricing service in certain limited circumstances. Short-term investments which mature within 60 days are valued at amortized cost, which approximates market value. The senior loans in which the Fund primarily invests are not listed on an organized exchange and the secondary market for such investments is less liquid relative to markets for other fixed income securities. Consequently, the value of a senior loan, determined as described above, may differ significantly from the value that would have been determined had there been an active market for that senior loan. Investment Transactions Investment transactions are recorded on a trade date basis. Trade date for senior loans purchased in the primary market is considered the date on which the loan allocations are determined. Realized gains and losses from investment transactions are determined on the specific identification method. Investments purchased on a when-issued or delayed delivery basis may have extended settlement periods. Any investments so purchased are subject to market fluctuation during this period. The Fund has instructed the custodian to segregate assets with a current value at least equal to the amount of the when-issued and delayed delivery purchase commitments. At January 31, 2004, the Fund had no such outstanding purchase commitments. Investment Income Interest income, which includes the amortization of premiums and accretion of discounts, is recorded on an accrual basis. Interest income also includes paydown gains and losses on senior loans. Facility fees on senior loans purchased are treated as market discounts. Market premiums and discounts are amortized over the expected life of each respective borrowing. Fees consists primarily of amendment fees. Amendment fees are earned as compensation for evaluating and accepting changes to the original credit agreement. Income Taxes The Fund intends to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its net investment income to its shareholders. Therefore, no federal income tax provision is required. 17 Notes to FINANCIAL STATEMENTS (Unaudited) (continued) Dividends and Distributions to Common Shareholders The Fund intends to declare monthly income distributions to Common shareholders. Net realized capital gains from investment transactions, if any, are distributed to shareholders not less frequently than annually. Furthermore, capital gains are distributed only to the extent they exceed available capital loss carryforwards. Distributions to Common shareholders of net investment income and net realized capital gains, if any, are recorded on the ex-dividend date. The amount and timing of distributions are determined in accordance with federal income tax regulations, which may differ from accounting principles generally accepted in the United States. Taxable Auctioned Preferred Shares The Fund has issued and outstanding 1,840 Series Th, $25,000 stated value Taxable Auctioned Preferred shares. The dividend rate paid on the Taxable Auctioned Preferred shares may change every 28 days, as set pursuant to a dutch auction process by the auction agent, and is payable at or near the end of each rate period. Derivative Financial Instruments The Fund may invest in certain derivative financial instruments including futures, forward, swap and option contracts, and other financial instruments with similar characteristics. Although the Fund is authorized to invest in such financial instruments, and may do so in the future, it did not make any such investments during the six months ended January 31, 2004. Repurchase Agreements In connection with transactions in repurchase agreements, it is the Fund's policy that its custodian take possession of the underlying collateral securities, the fair value of which exceeds the principal amount of the repurchase transaction, including accrued interest, at all times. If the seller defaults, and the fair value of the collateral declines, realization of the collateral may be delayed or limited. Custodian Fee Credit The Fund has an arrangement with the custodian bank whereby certain custodian fees and expenses are reduced by credits earned on the Fund's cash on deposit with the bank. Such deposit arrangements are an alternative to overnight investments. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States 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 increases and decreases in net assets applicable to Common shares from operations during the reporting period. Actual results may differ from those estimates. 2. FUND SHARES During the six months ended January 31, 2004, 11,358 Common shares were issued to shareholders due to reinvestment of distributions. During the fiscal year ended July 31, 2003, 14,141 Common shares were issued to shareholders due to reinvestment of distributions. 3. INVESTMENT TRANSACTIONS Purchases and sales of investments (excluding short-term investments) during the six months ended January 31, 2004, aggregated $232,181,352 and $203,876,379, respectively. 18 4. INCOME TAX INFORMATION The following information is presented on an income tax basis. Differences between amounts for financial statement and federal income tax purposes are primarily due to the treatment of paydown gains and losses on investments and timing differences in recognizing certain gains and losses on investment transactions. At January 31, 2004, the cost of investments owned was $400,173,850. The net unrealized depreciation of investments at January 31, 2004, aggregated $6,526,474 of which $8,294,668 related to appreciated securities and $14,821,142 related to depreciated securities. The tax components of undistributed net ordinary income and net realized gains at July 31, 2003, the Fund's last fiscal year end, were as follows: -------------------------------------------------------------------------------- Undistributed net ordinary income * $2,019,827 Undistributed net long-term capital gains -- ================================================================================ * Net ordinary income consists of net taxable income derived from dividends, interest and net short-term capital gains, if any. The tax character of distributions paid during the fiscal year ended July 31, 2003, the Fund's last fiscal year end, was designated for purposes of the dividends paid deduction as follows: -------------------------------------------------------------------------------- Distributions from net ordinary income * $16,734,378 Distributions from net long-term capital gains -- ================================================================================ * Net ordinary income consists of net taxable income derived from dividends, interest and net short-term capital gains, if any. At July 31, 2003, the Fund's last fiscal year end, the Fund had an unused capital loss carryforward of $28,988,118 available to be applied against future capital gains, if any. If not applied, $18,283,863 of the carryforward will expire in 2010 and $10,704,255 will expire in 2011. 5. MANAGEMENT FEES AND OTHER TRANSACTIONS WITH AFFILIATES Under the Fund's investment management agreement with the Adviser, the Fund pays an annual management fee, payable monthly, of .8500%, which is based upon the average daily managed assets of the Fund. "Managed Assets" means the average daily gross asset value of the Fund, minus the sum of the Fund's accrued and unpaid dividends on any outstanding Taxable Auctioned Preferred shares and accrued liabilities (other than the principal amount of any borrowings incurred, commercial paper or notes issued by the Fund and the liquidation preference of any outstanding Taxable Auctioned Preferred shares). The management fee compensates the Adviser for overall investment advisory and administrative services and general office facilities. The Adviser has entered into a Sub-Advisory Agreement with Symphony Asset Management ("Symphony"), an indirect wholly owned subsidiary of Nuveen Investments, Inc., under which Symphony manages the investment portfolio of the Fund. Symphony is compensated for its services to the Fund from the management fee paid to the Adviser. The Fund pays no compensation directly to those of its Trustees who are affiliated with the Adviser or to their officers, all of whom receive remuneration for their services to the Fund from the Adviser or its affiliates. The Adviser has agreed to waive part of its management fees or reimburse certain expenses of the Fund in an amount equal to .45% of the average daily Managed Assets for the period October 29, 1999 (commencement of operations) through October 31, 2004, .35% of the average daily Managed Assets for the year ended October 31, 2005, .25% of the average daily Managed Assets for the year ended October 31, 2006, .15% of the average daily Managed Assets for the year ended October 31, 2007, .10% of the average daily Managed Assets for the year ended October 31, 2008, and .05% of the average daily Managed Assets for the year ended October 31, 2009. The Adviser has not agreed to reimburse the Fund for any portion of its fees and expenses beyond October 31, 2009. 19 Notes to FINANCIAL STATEMENTS (Unaudited) (continued) 6. COMMITMENTS Pursuant to the terms of certain of the variable rate senior loan agreements, the Fund may have unfunded senior loan commitments. The Fund will maintain with its custodian, cash, liquid securities and/or liquid senior loans having an aggregate value at least equal to the amount of unfunded senior loan commitments. At January 31, 2004, there were no such unfunded senior loan commitments. 7. SENIOR LOAN PARTICIPATION COMMITMENTS The Fund invests primarily in assignments, participations, or acts as a party to the primary lending syndicate of a variable rate senior loan interest to corporations, partnerships, and other entities. If the Fund purchases a participation of a senior loan interest, the Fund would typically enter into a contractual agreement with the lender or other third party selling the participation, but not with the borrower directly. As such, the Fund assumes the credit risk of the Borrower, Selling Participant or other persons interpositioned between the Fund and the Borrower. At January 31, 2004, the Fund held senior loan participation commitments with Bear, Stearns &Co. Inc. and Morgan Stanley Emerging Markets Inc. At January 31, 2004, the par values of the commitments were $2 million and $1.64 million, respectively, while the market values were approximately $1.95 million and $1.6 million, respectively. 8. BORROWINGS In accordance with its current investment policies, the Fund may utilize financial leverage for investment purposes in an amount currently anticipated to represent approximately 40% of the Fund's total assets, and in no event exceeding 50% of the Fund's total assets. Through June 19, 2003, the Fund entered into a $150 million commercial paper program with Nuveen Funding, LLC, a Delaware limited liability company whose sole purpose was the issuance of commercial paper. On June 20th, 2003, the commercial paper program with Nuveen Funding, LLC, was terminated. On June 20, 2003, the Fund entered into a commercial paper program with Bank One's conduit financing agency, Falcon Asset Securitization Corp. ("Falcon"), whose sole purpose is the issuance of high grade commercial paper. Falcon uses the proceeds to make advances to the Fund and to many other borrowers who comprise Falcon's total borrowing base. For the six months ended January 31, 2004, the average daily balance of borrowings under the commercial paper program agreement was $103 million with an average interest rate of 1.12%. The Fund has also entered into a $110 million liquidity facility. If the facility is utilized, interest on the borrowings would be charged a variable interest rate. An unused commitment fee of .095% on 102% of the unused portion of the $110 million facility is charged. There were no borrowings under the revolving credit agreement during the six months ending January 31, 2004. Cash paid for interest during the six months ended January 31, 2004, was $619,905. 9. SUBSEQUENT EVENT - DISTRIBUTIONS TO COMMON SHAREHOLDERS The Fund declared a dividend distribution of $.0430 per Common share from its net investment income which was paid on March 1, 2004, to shareholders of record on February 15, 2004. 20 Financial HIGHLIGHTS (Unaudited) 21 Financial HIGHLIGHTS (Unaudited) Selected data for a Common share outstanding throughout each period: Investment Operations Less Distributions ------------------------------------------------------------------- --------------------------------- Distributions Distributions from Net from Net Beginning Net Investment Capital Investment Capital Common Realized/ Income to Gains to Income to Gains to Share Net Unrealized Preferred Preferred Common Common Net Asset Investment Investment Share- Share- Share- Share- Value Income Gain (Loss) holders+ holders+ Total holders holders Total =================================================================================================================================== Year Ended 7/31: 2004(b) $7.84 $ .34 $ .38 $(.01) $-- $ .71 $ (.26) $-- $ (.26) 2003 7.38 .60 .41 (.02) -- .99 (.53) -- (.53) 2002 8.13 .68 (.71) (.04) -- (.07) (.68) -- (.68) 2001 9.47 1.09 (1.29) (.09) -- (.29) (1.03) (.02) (1.05) 2000(a) 9.55 .75 (.12) (.02) -- .61 (.66) -- (.66) =================================================================================================================================== Total Returns ----------------- Based on Ending Common Common Based Share Share Ending on Net Offering Net Asset Market Market Asset Costs Value Value Value** Value** ================================================================================ Year Ended 7/31: 2004(b) $ -- $8.29 $9.3200 13.88% 9.16% 2003 -- 7.84 8.4300 25.93 14.25 2002 -- 7.38 7.2000 (21.16) (.65) 2001 -- 8.13 9.9600 15.35 (3.30) 2000(a) (.03) 9.47 9.6250 3.21 6.20 ================================================================================ Ratios/Supplemental Data ---------------------------------------------------------------------------------------------- Before Credit/Waiver After Credit/Waiver*** ---------------------------- ---------------------------- Ratio of Net Ratio of Net Ratio of Investment Ratio of Investment Ending Expenses Income to Expenses Income to Net to Average Average to Average Average Assets Net Assets Net Assets Net Assets Net Assets Applicable Applicable Applicable Applicable Applicable Portfolio to Common to Common to Common to Common to Common Turnover Shares (000) Shares++ Shares++ Shares++ Shares++ Rate ==================================================================================================================== Year Ended 7/31: 2004(b) $246,715 2.29%* 7.59%* 1.56%* 8.31%* 56% 2003 233,220 2.66 7.57 1.90 8.33 80 2002 219,459 3.12 8.20 2.37 8.95 64 2001 241,641 4.32 11.74 3.62 12.44 52 2000(a) 280,479 3.81* 9.82* 3.21* 10.42* 40 ==================================================================================================================== * Annualized. ** Total Investment Return on Market Value is the combination of reinvested dividend income, reinvested capital gains distributions, if any, and changes in stock price per share.

A phone call is all it takes to set up your reinvestment account. NUVEEN CLOSED-END EXCHANGE-TRADED FUNDS DIVIDEND REINVESTMENT PLAN Your Nuveen Closed-End Exchange-Traded Fund allows you to conveniently reinvest dividends and/or capital gains distributions in additional fund shares. By choosing to reinvest, you'll be able to invest money regularly and automatically, and watch your investment grow through the power of compounding. It is important to note that an automatic reinvestment plan does not ensure a profit, nor does it protect you against loss in a declining market. EASY AND CONVENIENT To make recordkeeping easy and convenient, each month you'll receive a statement showing your total dividends and distributions, the date of investment, the shares acquired and the price per share, and the total number of shares you own. HOW SHARES ARE PURCHASED The shares you acquire by reinvesting will either be purchased on the open market or newly issued by the Fund. If the shares are trading at or above net asset value at the time of valuation, the Fund will issue new shares at the greater of the net asset value or 95% of the then-current market price. If the shares are trading at less than net asset value, shares for your account will be purchased on the open market. Dividends and distributions received to purchase shares in the open market will normally be invested shortly after the dividend payment date. No interest will be paid on dividends and distributions awaiting reinvestment. Because the market price of shares may increase before purchases are completed, the average purchase price per share may exceed the market price at the time of valuation, resulting in the acquisition of fewer shares than if the dividend or distribution had been paid in shares issued by the Fund. A pro rata portion of any applicable brokerage commissions on open market purchases will be paid by Plan participants. These commissions usually will be lower than those charged on individual transactions. FLEXIBILITY You may change your distribution option or withdraw from the Plan at any time, should your needs or situation change. Should you withdraw, you can receive a certificate for all whole shares credited to your reinvestment account and cash payment for fractional shares, or cash payment for all reinvestment account shares, less brokerage commissions and a $2.50 service fee. You can reinvest whether your shares are registered in your name, or in the name of a brokerage firm, bank, or other nominee. Ask your investment advisor if his or her firm will participate on your behalf. Participants whose shares are registered in the name of one firm may not be able to transfer the shares to another firm and continue to participate in the Plan. The Fund reserves the right to amend or terminate the Plan at any time. Although the Fund reserves the right to amend the Plan to include a service charge payable by the participants, there is no direct service charge to participants in the Plan at this time.

It expresses the return (including change in NAV and reinvested dividends) that would have been necessary on an annual basis to equal the investment's actual performance over the time period being considered. NET ASSET VALUE (NAV): A fund's NAV is calculated by subtracting the liabilities of the fund from its total assets and then dividing the remainder by the number of shares outstanding. Fund NAVs are calculated at the end of each business day. -------- The Fund intends to repurchase shares of its own common or preferred stock in the future at such times and in such amounts as is deemed advisable. No shares were repurchased during the period ended January 31, 2004. Any future repurchases will be reported to shareholders in the next annual or semiannual report. 25 Serving Investors FOR GENERATIONS Since 1898, financial advisors and their clients have relied on Nuveen Investments to provide dependable investment solutions.
