Dear Shareholder The awful events of September 11, 2001, have touched all of us, and our hearts and thoughts go out to those directly affected by the terrible tragedies in New York, Washington and Pennsylvania. In the aftermath of these horrible acts, the financial markets have reacted with volatility and uncertainty as investors attempt to understand what has happened and how it might affect the future. The prices of many investments have moved sharply in recent days, and shares of your Fund have followed this general trend. It is too early to tell what the long-term impact will be on the markets or your Fund, but one thing that is increasingly clear to us is that a diversified portfolio can leave you well positioned to reduce overall investment volatility. For example, during the period covered by this report, your Fund continued to meet its primary objective of providing an attractive monthly income from a portfolio of carefully researched senior loans. Detailed information on your Fund can be found in the Manager's Perspective and Performance Overview sections later in this report. I urge you to take the time to read them. In addition to providing you with steady income, your Nuveen Fund also features several characteristics that can help make it an essential part of your overall investment strategy. These include constant surveillance and judicious trading by Nuveen's portfolio management team, with every action designed to supplement income, improve Fund structure, better adapt to current market conditions or increase diversification. In turbulent times like these, prudent investors understand the importance of diversification, balance, and risk management, all attributes your Nuveen Fund can bring to your portfolio. For more than 100 years, Nuveen has specialized in offering quality investments to those seeking to accumulate and preserve wealth to estab lish a lasting legacy. Our mission continues to be to provide assistance to you and your financial advisor by offering investment services and products that can help you leave your mark. We thank you for continuing to choose Nuveen Investments as your partner as you work toward that goal. Sincerely, /s/ Timothy R. Schwertfeger Timothy R. Schwertfeger Chairman of the Board September 24, 2001 Nuveen Senior Income Fund (NSL) Manager's Perspective Jeffrey Maillet, manager of the Fund during the period covered by this report, discusses economic conditions, the market environment, key investment strategies and the performance of NSL. After completion of the Fund's reporting period, Jeff announced his intention to leave Nuveen, and he is now working with Company officials to ensure an orderly and efficient man agement transition. We expect this process to be completed by November 1, 2001, and we look forward to introducing the new manager in the next shareholder report. Q. WHAT WAS THE GENERAL MARKET ENVIRONMENT OVER THE PAST TWELVE MONTHS? A. First, let's take a look at the Fund's reporting period, which covers the twelve months ending July 31, 2001. At the beginning of the reporting period, the Fed had just completed the last of six short-term interest rate hikes that ended with the federal funds rate at 6.50%, and though the economy was beginning to show signs of slowing, fundamentals appeared strong. In the months that followed, our key concern became rising petroleum prices, which we believed could have greater negative impact on the economy overall than tightened money supply. As we entered 2001, declines in corporate spending and faltering financial markets clearly pointed to a weakening economy, making the specter of rising energy costs all the more worrisome. As an economic downturn became more apparent, the Fed reversed course and began reducing interest rates aggressively. So far in 2001, they have reduced rates on six separate occasions bringing the federal funds rate to 3.50% from 6.50% at the start of the period. (On September 17 the Fed lowered rates again, bringing the fed funds rate to 3.00%.) As of yet, interest rate reductions have not provided a substantial boost to the economy and slowing economic growth has reduced the underlying credit quality of some borrow ers within the senior loan market. Reduced availability of capital caused by the turbulence in the financial markets has forced some companies to suspend or discontinue at least a portion of operations and raised the possi bility that others would be unable to avoid a negative credit event. As a result, corporate defaults in the high yield market have escalated to 7.25% through the first half of the year compared to 4.50% at the beginning of 2001 according to Credit Suisse First Boston. The slowing economy and rising defaults have made for a relatively difficult period for the senior loan markets. It is too early to know how the market or the economy ultimately will react to the tragic events of September 11. In the first several trading days after the attacks, we witnessed increased price volatility, with prices and NAVs generally trending lower. The economic forecasts remain uncertain, but we believe the country will rebound and that many sectors now under pressure may be strong performers in the future. Q. HOW DID THE FUND PERFORM ON A TOTAL RETURN BASIS DURING THE YEAR ENDED JULY 31, 2001, AND WHAT FACTORS INFLUENCED ITS RETURNS? A. As of July 31, 2001, NSL offered a very attractive dividend yield. This strong dividend yield was complemented by a strong stock price, enabling NSL to outperform the other closed-end senior loan funds on a total return basis over the twelve months ended July 31 when computed on stock price. As shown in the chart below, the fund outperformed its peer group average total returns for the one-year and since inception periods based upon stock price. Cumulative Total Returns1 On Market Price -------------------------------------------------------- 1-Year Since Inception2 -------------------------------------------------------- Nuveen Senior Income Fund 15.35% 19.07% Lipper Loan Participation Funds Category average3 7.06% 11.43% -------------------------------------------------------- These returns outpaced major stock indices during the one-year period, including the NASDAQ, which plummeted - 46.05 percent, and the S&P 500, down -14.33 percent. The difficulties experienced in so many financial markets during the period illustrate why we believe a diversified asset allocation plan that includes investments like the Nuveen Senior Income Fund may help to reduce an investor's overall risk. While the Fund's dividend remained attractive over the period, declining interest rates did put pressure of the Fund's earnings, leading to three dividend reductions since the begin ning of 2001. Due to the short average days-to-reset for the coupons of the loans held with the Fund, falling interest rates typically have negatively impacted the distribution rate for the Fund. However, the securities held within the Fund's portfolio typically yielded a premium of approximately 250 to 450 basis points over short-term interest rates. We believe the dividend paid by the Fund should remain relatively attractive in comparison to other short-term alternatives, which also tend to decline in a falling interest rate environment. Increased uncertainty created by the rise in the number of defaults within the marketplace has placed some negative pressure on the Fund's net asset value. The Fund started the period with a net asset value of $9.47 on July 31, 2000, and finished the period at $8.13 as of July 31, 2001. This decline in NAV may be attributed to escalating default rates in the senior loan arena, which have created a significant amount of downward pressure on the market in general. Q. WHAT DIFFERENTIATES YOUR FUND FROM THE OTHER EXCHANGE-TRADED CLOSED-END SENIOR LOAN FUNDS IN THE MARKET? A. NSL maintains a very competitive leverage structure. NSL employs a two-tier leverage approach consisting of both commercial paper and taxable auction rate preferred shares. The Fund issues commercial paper directly to the market along with auction rate preferred shares. The innovative structure allows the Fund to employee a slightly higher degree of leverage than a simple credit facility or commercial paper alone and is currently a much less expensive alternative. This typically translates into a higher earning potential for the Fund. 1 Returns are historical and do not guarantee future performance. Investment returns and principal value will fluctuate so that when shares are redeemed, they may be worth more or less than their original cost. 2 NSL commenced operations on October 29, 1999. 3 The Lipper Loan Participation Funds category consists of 43 Funds. Both NSL and Lipper returns assume reinvestment of dividends. In addition, the fee structure also helps to differentiate the Fund from the other closed-end senior loan funds available in the market. Under the structure, Nuveen reimburses 45 bp of the Fund's 85 bp management fee for the first five years of the Fund's operation. After which, the expense reimbursement will be gradually phased out for the following five years. This is designed to increase the opportunity for more income to shareholders in the early years of the Fund's operations. The lower overall fees, especially when compared to the peer group of funds, provides a slight advantage over the other Funds in the marketplace. Q. HOW DO YOU VIEW THE CURRENT DEFAULT RISK WITHIN THE SENIOR LOAN MARKET? WHAT SECTORS DO YOU FEEL ARE SUSCEPTIBLE TO HIGH DEFAULT RATES? A. With expected lower economic growth in the U.S. economy, the potential for defaults in the Senior Loan Market has escalated. As mentioned earlier, average default rates have increased significantly from the historical aver ages over the last 18 to 24 months. However, the fact that the Fund invests primarily in senior secured loans, a particular default does not necessarily indicate a devastating event for the shareholder. The loans are typically collateralized and the senior loan holders maintain a priority status in the restructuring and workout of a defaulted creditor. This can lead to substantially higher recovery rates on defaulted assets in comparison to many other types of corporate debt instruments. Areas that are currently facing increased levels of risk would be the Competitive Local Exchange Carriers (CLECs) in the telecom sector. Several companies have lost vender provided financing to build their networks. We feel the spill over effect of a tough capital market environment has compounded these problems. However, these factors should be resolved over time. In addition to the CLECs, steel and auto parts manufacturers have come under pressure recently with the slowing economy. Q. WHAT IS YOUR OUTLOOK FOR THE SENIOR LOAN MARKET AND PLANS FOR THE NUVEEN SENIOR INCOME FUND? A. In the wake of September 11, we will continue to evaluate various sectors and credits in an attempt to identify opportu nities that may arise out of the uncertainty. The supply of attractive new senior loan assets may experi ence a slight fall off. However, we feel many existing loans now offer a substantial amount of value given current trading levels. Our efforts will focus on taking advantage of opportuni ties in the strongest sectors of the senior loan market while being mindful of the current uncertainty within the market overall.

Ratings are not covered by the Report of Independent Auditors. ** Senior Loans in the Fund's portfolio generally are subject to mandatory and/or optional prepayment. 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) Senior Loans in which the Fund invests generally pay interest at rates which are periodically redetermined by reference to a base 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, and (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 July 31, 2001, this issue was non-incoming producing. (b) At or subsequent to July 31, 2001, this issue was under the protection of the federal bankruptcy court.

Notes to Financial Statements 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 is listed on the New York Stock Exchange and trades under the ticker symbol "NSL". The Fund was organized as a Massachusetts business trust on August 13, 1999. Prior to commencement of operations on October 29, 1999, the Fund had no operations other than those related to organizational matters and the initial capital contribution of $100,084 by Nuveen Senior Loan Asset Management Inc. (the "Adviser"), a wholly owned subsidiary of The John Nuveen Company. The Fund seeks to provide a high level of current income, consistent with preservation of capital 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 and bonds in the Fund's investment portfolio are provided by independent pricing services approved by the Fund's Board of Trustees. The pricing service providers typically value senior loans and bonds at the mean of the highest bona fide bid and lowest bona fide ask prices when current quotations are readily available. Senior loans and bonds for which current quotations are not readily available are valued at fair value using a wide range of market data and other information and analysis, including credit characteristics considered relevant by such pricing service providers to determine valuations. The Board of Trustees of the Fund has approved procedures which permit the Adviser to override the price provided by the independent pricing service. There were no senior loan price overrides during the fiscal year ended July 31, 2001; however, the Adviser did override one bond price during the fiscal year ended July 31, 2001. Short-term investments which mature within 60 days are valued at amortized cost, which approximates market value. The senior loans in which the Fund invests are generally not listed on any exchange and the secondary market for those senior loans is comparatively illiquid relative to markets for other fixed income securities. Because of the comparatively illiquid markets, the value of a senior loan may differ significantly from the value that would have been used had there been an active market for that senior loan. Investment Transactions Investment transactions are recorded on a trade date basis. Investment Income Interest income is determined on the basis of interest accrued, adjusted for amortization of premiums and accretion of discounts. 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 reviewing 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. Dividends and Distributions to Shareholders The Fund intends to declare and pay monthly distributions to Common Shareholders. Generally payment is made or reinvestment is credited to shareholder accounts on the first business day after month-end. 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. Notes to Financial Statements (continued) Distributions to shareholders of net investment income, and net realized capital gains 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. Accordingly, temporary over-distributions as a result of these differences may occur and will be classified as either distributions in excess of net investment income and/or distributions in excess of net realized gains from investment transactions, where applicable. Permanent differences between financial and tax basis reporting for the fiscal year have been identified and appropriately reclassified. During the fiscal year ended July 31, 2001, permanent differences relating to expenses which are not deductible for tax purposes totaling $82,779 were reclassified from undistributed net investment income to capital. Taxable Auctioned Preferred Shares On May 30, 2000, the Fund issued 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 by the auction agent. 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 fiscal year ended July 31, 2001. Offering Costs Costs incurred by the Fund in connection with its offering of Common and Taxable Auctioned Preferred Shares were recorded as a reduction of the proceeds from the sale of the shares. 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 from operations during the reporting period. Actual results may differ from those estimates. Audit Guide In November 2000, the American Institute of Certified Public Accountants (AICPA) issued a revised version of the AICPA Audit and Accounting Guide for Investment Companies (the "Guide"). The Guide is effective for annual financial statements issued for fiscal years beginning after December 15, 2000. It is not anticipated that the adoption of the Guide will have a significant effect on the financial statements. 2. FUND SHARES During the fiscal year ended July 31, 2001, 81,022 Common Shares were issued to shareholders due to reinvestment of distributions. During the period October 29, 1999 (commencement of operations)through July 31, 2000, 29,600,000 Common Shares and 1,840 Taxable Auctioned Preferred Shares were sold and 17,563 Common Shares were issued to shareholders due to reinvestment of distributions. 3. DISTRIBUTIONS TO COMMON SHAREHOLDERS The Fund declared a dividend distribution of $.0790 per Common Share from its net investment income which was paid on September 4, 2001, to shareholders of record on August 15, 2001. The Fund also declared a dividend distribution of $.0750 per Common Share from its net investment income which will be paid on October 1, 2001, to shareholders of record on September 15, 2001. 4. INVESTMENT TRANSACTIONS Purchases and sales of investments (excluding short-term investments) during the fiscal year ended July 31, 2001, aggregated $227,246,684 and $198,578,912, respectively. At July 31, 2001, the identified cost of investments owned for federal income tax purposes was $433,067,293. 5. UNREALIZED APPRECIATION (DEPRECIATION) At July 31, 2001, net unrealized depreciation of investments for federal income tax purposes aggregated $42,644,173 of which $3,151,636 related to appreciated investments and $45,795,809 related to depreciated investments. 6. 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 of 1%, which is based upon the average daily managed assets of the Fund. "Managed assets" shall mean 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 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. The management fee compensates the Adviser for overall investment advisory and administrative services and general office facilities. 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. 7. COMPOSITION OF NET ASSETS At July 31, 2001, net assets consisted of: -------------------------------------------------------------------------------- Taxable Auctioned Preferred Shares, $25,000 stated value per share, at liquidation value $ 46,000,000 Common Shares, $.01 par value per share 297,091 Paid-in surplus 282,325,151 Balance of undistributed net investment income 1,596,263 Accumulated net realized gain (loss) from investment transactions (17,495,522) Net unrealized appreciation (depreciation) of investments (25,081,557) -------------------------------------------------------------------------------- Net assets $287,641,426 ================================================================================ Authorized shares: Common Unlimited Preferred Unlimited ================================================================================ 8. COMMITMENTS Pursuant to the terms of certain of the Variable Rate Senior Loan agreements, the Fund had unfunded loan commitments of $4.6 million as of July 31, 2001. The Fund generally will maintain with its custodian short-term investments and/or cash having an aggregate value at least equal to the amount of unfunded loan commitments. 9. 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 July 31, 2001, the Fund held one participation commitment with Chase Manhattan Bank. At July 31, 2001, the par value of this commitment is $10 million while the market value is $9.4 million. 10. 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. On May 23, 2000, the Fund entered into a $150 million commercial paper program with Nuveen Funding, L.L.C., a Delaware limited liability company whose sole purpose is the issuance of commercial paper. Nuveen Funding, L.L.C. has the authority to issue a maximum of $150 million of commercial paper, at a discount, with maturities of up to 180 days, the proceeds of which are used to make advances to the Fund. This line of credit is secured by the assets of the Fund. For the fiscal year ended July 31, 2001, the average daily balance of borrowings under the commercial paper program agreement was $97.5 million with an average interest rate of 5.85%. The Fund has entered into a $155 million revolving credit agreement with Deutsche Bank AG which expires May 2002. Interest on borrowings is charged at a rate of either the Fed Funds rate plus .50%, LIBOR plus .50% or the Prime Rate. An unused commitment fee of .125% is charged on the unused portion of the facility.

Build Your Wealth Automatically NUVEEN EXCHANGE-TRADED FUNDS DIVIDEND REINVESTMENT PLAN Your Nuveen 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 tax-free compounding. Just like dividends or distributions in cash, there may be times when income or capital gains taxes may be payable on dividends or distrib utions that are reinvested. It is important to note that an automatic reinvest-ment 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 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.
