Schwertfeger Chairman of the Board CHAIRMAN'S LETTER TO SHAREHOLDERS Dear Shareholder: I am very pleased to report that over the twelve-month period covered by this report, your Fund continued to provide you with attractive monthly distributions from a portfolio primarily composed of senior corporate loans. For more information on your Fund's performance, please read the Portfolio Managers' Comments, the Distribution and Share Price Information, and the Performance Overview sections of this report. Portfolio diversification is a recognized way to try to reduce some of the risk that comes with investing. Since one part of your portfolio may be going up when another is going down, portfolio diversification may help smooth your investment returns over time. In addition to providing regular monthly income, an investment like your Fund may help you achieve and benefit from greater portfolio diversification. Your financial advisor can explain these potential advantages in more detail. I urge you to contact him or her soon for more information on this important investment strategy. "IN ADDITION TO PROVIDING REGULAR MONTHLY INCOME, AN INVESTMENT LIKE YOUR FUND MAY HELP YOU ACHIEVE AND BENEFIT FROM GREATER PORTFOLIO DIVERSIFICATION." At Nuveen Investments, our mission continues to be to assist you and your financial advisor by offering investment services and products that can help you to secure your financial objectives. We are grateful that you have chosen us as a partner as you pursue your financial goals, and we look forward to continuing to earn your trust in the months and years ahead. Sincerely, (TIMOTHY SCHWERTFEGER SIG) Timothy R. Schwertfeger Chairman of the Board September 12, 2006 Nuveen Investments Exchange-Traded Closed-End Funds (NSL, JFR, JRO) PORTFOLIO MANAGERS' COMMENTS The Funds' investment portfolios are managed by Gunther Stein and Lenny Mason of Symphony Asset Management, LLC, an affiliate of Nuveen Investments. 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 Gunther and Lenny talk about their management strategies and the performances of the Funds for the twelve month period ended July 31, 2006. WHAT WERE THE GENERAL ECONOMIC AND MARKET CONDITIONS YOU FACED DURING THIS ANNUAL REPORTING PERIOD ENDED JULY 31, 2006? For much of the twelve month period ended July 31, 2006, the loan market remained governed by one overriding characteristic, strong investor demand exceeding supply. This strong investor demand was driven by near historic low default rates, rising interest rates and demand from structured loan vehicles, resulting in tightening spreads. Nevertheless, in the quarter ended July 31 the conditions that had been prevalent for so long reversed and selling picked up in the loan and high yield markets during the latter part of this quarter. Investors sold loans with spreads under LIBOR +200 (London Interbank Offered Rate), the demand from non-traditional investors fell and supply exceeded demand. As loan market conditions reversed, secondary loan prices came down and new-issue spreads widened. By period end, according to Standard & Poor's loan index, the average BB/BB- spread reached LIBOR +193 and the average B+/B spread finished the period at LIBOR +277. However, at the end of the twelve month period the Credit Suisse loan Index had returned 45 consecutive months of positive returns. Despite some volatility in the markets during this period due to inflationary pressures and rising interest rates, the loan market remained robust. Total loan volume through the annual period rose steadily. In the quarter ended July 31, loan volume reached a new record high of $128 billion, up from $116 billion during the prior quarter. While recent volume data is impressive, it is important to understand total volume in the context of the record demand that has been prevalent in the loan market recently. Though the markets were volatile in the latter part of the period, the Credit Suisse Leveraged Loan Index, the Credit Suisse BB leveraged loan index, and the Credit Suisse single-B index all posted positive returns for the 12-month period. Default rates have been near historic lows over the past two years, as the economy continued to expand. The default rate in the leveraged loan market stood at approximately 2% for 2005. In 4 the current credit environment, higher credit quality assets have underperformed riskier assets. We believe the reversal in market sentiment that took place during the quarter ended July 31 could spillover into the coming quarters in the form of more balanced supply and demand. Although non traditional institutional investors have recently retreated from the loan market, they appear to be a permanent segment of the market going forward. The CLO (Collateralized Loan Obligation) pipeline, while still robust, has declined from record highs. These factors, combined with continued strong new issuance could better balance supply and demand. WHAT WAS YOUR MANAGEMENT STRATEGY DURING THIS TWELVE-MONTH PERIOD? In the first half of the year we avoided most automotive-related companies even though many were trading at seemingly attractive high yields. We also avoided many small loans that support leveraged buyouts, as we felt that market liquidity could be challenged if the credit experienced any negative events. We focused on adding high quality new issue loans at par as we did not believe that paying premiums for loans was prudent in the current environment. The volatility experienced during the quarter ended July 31 presented new opportunities in the new-issue market. Recently, we have seen an increase in new deals with attractive pricing, solid collateral and tighter covenants. A combination of these characteristics had been less prevalent recently in a strong market environment. During the twelve-month period, we also continued to avoid the vast majority of second lien loans. At current trading levels, we did not believe that most second lien loans compensated investors for the extra risk these credits pose over a credit cycle. Should the economy weaken, we believe that second lien loans could see significant downside from current levels. Overall, we continue to view the leveraged loan market favorably with near historic low default rates, improved market liquidity and new companies coming to market. Strong investor demand, however has allowed many deals to be structured with aggressive leverage levels. We do not feel that now is the appropriate time to be reaching for yield or be involved with what we consider to be marginal credits. We continue to position 5 the portfolio in a defensive manner, avoiding credits we feel are too aggressively leveraged or do not have a strong credit profile. HOW DID THE FUNDS PERFORM? The performance of each Fund over the twelve-month period ended July 31, 2006, as well as the performance of a comparative index, is shown below. TOTAL RETURN ON NET ASSET VALUE* For the periods ended July 31, 2006 1-YEAR 5-YEAR ---------------------------------------------------------------------------- NSL 5.78% 8.15% ---------------------------------------------------------------------------- JFR 5.72% -- ---------------------------------------------------------------------------- JRO 6.60% -- ---------------------------------------------------------------------------- CSFB Leveraged Loan Index(1) 6.40% 6.29% ---------------------------------------------------------------------------- -------------------------------------------------------------------------------- 1 The CSFB Leveraged Loan Index is an unmanaged, unleveraged index consisting of approximately $150 billion of tradable term loans with at least one year to maturity, and rated BBB or lower. The Index does not reflect the expenses of investing or other fund expenses. -------------------------------------------------------------------------------- * Annualized. The data shown represents past performance which is no guarantee of future results. Current performance may be higher or lower than the data shown. Returns do not reflect the deduction of taxes that a shareholder may have to pay on Fund distributions or upon the sale of Fund shares. For more information, please see the individual Fund Performance Overview pages in this report. Over the 12-month reporting period, the returns of NSL and JFR underperformed the CSFB Leveraged Loan Index and the returns of JRO outperformed the Index. All three Funds' benefited over this period from the strong performance of their holdings in Federal Mogul, a global supplier of automotive components. The Federal Mogul term loan traded up during the period due to the expectation that the company will emerge out of bankruptcy soon. Steady operations and financial results have showed progress in the company's Chapter 11 emergence. NSL also benefited from its position in Dobson, a diversified telecommunication company. The company reported solid first quarter EBITDA resulting from net subscriber growth due to improved churn and expects net subscriber additions above high end of guidance for the second quarter. During the quarter the company also tendered for its more expensive LIBOR +475 1st priority senior secured floating-rate notes due 2011 via a $250mm add-on to existing 8.375% senior secured notes due 2011. In JFR, the portfolio's position in Avago Technologies benefited performance as the company substantially deleveraged through asset sales and has also shown strong results in its core operations. The floating rate notes traded up as a result. 6 While very few portfolio positions experienced volatility during the annual period, each Fund had holdings that constrained performance over this twelve-month reporting period. In NSL, an issuer that experienced volatility was: Century Cable: The Century loan moved lower on speculation that the unsecured creditors litigation surrounding the Adelphia bankruptcy would structure Century creditor recovery such that it would be unfavorable to the loans. The form of the restructuring is still being negotiated. In JFR's portfolio, issuers that constrained performance were: Hovnanian: Hovnanian, a national homebuilder, was impacted by a decrease in new home orders and investor concern about a severe slowdown in homebuilding activity. This concern has been caused by increasing mortgage rates and a slowdown in new home orders. Investors will remain cautious until the homebuilding sector demonstrates stability in new home orders. Georgia Pacific: Georgia Pacific was acquired by Koch Industries. The bonds of the company traded down after the announcement of the leveraged buyout. 7 DISTRIBUTION AND SHARE PRICE INFORMATION Each of these Funds uses financial leverage in an effort to enhance its dividend-paying capabilities. While this strategy adds volatility to a Fund's net asset value (NAV) and share price, it generally works to enhance the amount of income a Fund has to distribute to its common shareholders, as long as the dividend rates the Fund pays to its preferred shareholders are less than the interest rates the Fund receives from its portfolio of loans. Since each of these Funds invests in adjustable rate loans, their income streams typically can be expected to rise or fall over time to reflect the movement of shorter-term interest rates. These rates generally were rising over this twelve-month reporting period ended July 31, 2006, and this led to one monthly dividend increase in NSL and four monthly dividend increases in both JFR and JRO. All of these Funds seek to pay dividends at rates that reflect each Fund's past results, and projected future performance. During certain periods, each Fund may pay dividends at a rate that may be more or less than the amount of net investment income actually earned by the Fund during the period. If a Fund has cumulatively earned more than it has paid in dividends, it holds the excess in reserve as undistributed net investment income (UNII), which is part of the Fund's NAV. Conversely, if a Fund has cumulatively paid dividends in excess of its earnings, the excess constitutes negative UNII that is likewise reflected in the Fund's NAV. Each Fund will, over time, pay all of its net investment income as dividends to shareholders. As of July 31, 2006, NSL and JRO had a positive UNII balance for both financial statement and tax purposes. JFR had a negative UNII balance for financial statement purposes and a positive UNII balance for tax purposes. As of July 31, 2006, NSL, JFR and JRO all traded at discounts to their NAVs, as shown below. 7/31/06 12-MONTH AVERAGE DISCOUNT DISCOUNT

INCOME FUND NUVEEN FLOATING RATE INCOME FUND NUVEEN FLOATING RATE INCOME OPPORTUNITY FUND We have audited the accompanying statements of assets and liabilities, including the portfolios of investments, of Nuveen Senior Income Fund, Nuveen Floating Rate Income Fund and Nuveen Floating Rate Income Opportunity Fund (the "Funds"), as of July 31, 2006, and the related statements of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, cash flows for the year then ended, and the financial highlights for each of the periods after July 31, 2003. These financial statements and financial highlights are the responsibility of the Funds' management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. The financial highlights of the Nuveen Senior Income Fund for each of the two years in the period ended July 31, 2003 were audited by other auditors whose report dated September 18, 2003, expressed an unqualified opinion on those financial highlights. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Funds' internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Funds' internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of July 31, 2006, by correspondence with the custodian, selling or agent banks and brokers or by other appropriate auditing procedures where replies from selling or agent banks or brokers were not received.

(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 an assigned fixed rate. These floating lending rates are generally (i) the lending rate referenced by the London Inter-Bank Offered Rate ('LIBOR'), or (ii) the prime rate offered by one or more major United States banks. Senior Loans may be considered 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. (3) Senior Loans 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 may occur. As a result, the actual remaining maturity of Senior Loans held may be substantially less than the stated maturities shown. (4) Ratings (not covered by the report of independent registered public accounting firm): Using the higher of Standard & Poor's or Moody's rating. Ratings below BBB by Standard & Poor's Group or Baa by Moody's Investor Service, Inc. are considered to be below investment grade. (5) Portion of position represents an unfunded Senior Loan commitment outstanding at July 31, 2006. (6) Borrowings payable as a percentage of total investments is (25.7%). (7) At or subsequent to July 31, 2006, this issue was under the protection of the Federal Bankruptcy Court. (8) Non-income producing security, in the case of a bond, generally denotes that the issuer has defaulted on the payment of principal or interest or has filed for bankruptcy. (9) Position represents a participation commitment outstanding at July 31, 2006. (10) Negative value represents unrealized depreciation on Senior Loan commitment at July 31, 2006. (11) Investment valued at fair value using methods determined in good faith by, or at the discretion of, the Board of Trustees. N/R Not rated. WI/DD Purchased on a when-issued or delayed delivery basis. 144A Investment is exempt from registration under Rule 144A of the Securities Act of 1933, as amended. These investments may only be resold in transactions exempt from registration which are normally those transactions with qualified institutional buyers. TBD Senior Loan purchased on a when-issued or delayed-delivery basis. Certain details associated with this purchase are not known prior to the settlement date of the transaction. In addition, Senior Loans typically trade without accrued interest and therefore a weighted average coupon rate is not available prior to settlement. At settlement, if still unknown, the borrower or counterparty will provide the Fund with the final weighted average coupon rate and maturity date. (PIK) In lieu of cash payment, interest accrued on 'Payment in Kind' investment increases principal outstanding.

Senior Loans may be considered 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. (3) Senior Loans 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 may occur. As a result, the actual remaining maturity of Senior Loans held may be substantially less than the stated maturities shown. (4) Ratings (not covered by the report of independent registered public accounting firm): Using the higher of Standard & Poor's or Moody's rating. Ratings below BBB by Standard & Poor's Group or Baa by Moody's Investor Service, Inc. are considered to be below investment grade. (5) Portion of position represents an unfunded Senior Loan commitment outstanding at July 31, 2006. (6) At or subsequent to July 31, 2006, this issue was under the protection of the Federal Bankruptcy Court. (7) Negative value represents unrealized depreciation on Senior Loan commitment at July 31, 2006. N/R Not rated. WI/DD Purchased on a when-issued or delayed delivery basis. DD1 Portion of investment purchased on a delayed delivery basis. 144A Investment is exempt from registration under Rule 144A of the Securities Act of 1933, as amended. These investments may only be resold in transactions exempt from registration which are normally those transactions with qualified institutional buyers. TBD Senior Loan purchased on a when-issued or delayed-delivery basis. Certain details associated with this purchase are not known prior to the settlement date of the transaction. In addition, Senior Loans typically trade without accrued interest and therefore a weighted average coupon rate is not available prior to settlement. At settlement, if still unknown, the borrower or counterparty will provide the Fund with the final weighted average coupon rate and maturity date. (PIK) In lieu of cash payment, interest accrued on "Payment in Kind" investment increases principal outstanding.

(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 an assigned fixed rate. These floating lending rates are generally (i) the lending rate referenced by the London Inter-Bank Offered Rate ("LIBOR"), or (ii) the prime rate offered by one or more major United States banks. Senior Loans may be considered 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. (3) Senior Loans 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 may occur. As a result, the actual remaining maturity of Senior Loans held may be substantially less than the stated maturities shown. (4) Ratings (not covered by the report of independent registered public accounting firm): Using the higher of Standard & Poor's or Moody's rating. Ratings below BBB by Standard & Poor's Group or Baa by Moody's Investor Service, Inc. are considered to be below investment grade. (5) Portion of position represents an unfunded Senior Loan commitment outstanding at July 31, 2006. (6) At or subsequent to July 31, 2006, this issue was under the protection of the Federal Bankruptcy Court. (7) Negative value represents unrealized depreciation on Senior Loan commitment at July 31, 2006. N/R Not rated. WI/DD Purchased on a when-issued or delayed delivery basis. DD1 Portion of investment purchased on a delayed delivery basis. 144A Investment is exempt from registration under Rule 144A of the Securities Act of 1933, as amended. These investments may only be resold in transactions exempt from registration which are normally those transactions with qualified institutional buyers. TBD Senior Loan purchased on a when-issued or delayed-delivery basis. Certain details associated with this purchase are not known prior to the settlement date of the transaction. In addition, Senior Loans typically trade without accrued interest and therefore a weighted average coupon rate is not available prior to settlement. At settlement, if still unknown, the borrower or counterparty will provide the Fund with the final weighted average coupon rate and maturity date. (PIK) In lieu of cash payment, interest accrued on "Payment in Kind" investment increases principal outstanding.

Non-cash financing activities not included herein consist of reinvestments of Common share distributions of $64,606 for Senior Income (NSL). See accompanying notes to financial statements. 34 Notes to FINANCIAL STATEMENTS 1. GENERAL INFORMATION AND SIGNIFICANT ACCOUNTING POLICIES The funds (the "Funds") covered in this report and their corresponding Common share New York Stock Exchange symbols are Nuveen Senior Income Fund (NSL), Nuveen Floating Rate Income Fund (JFR) and Nuveen Floating Rate Income Opportunity Fund (JRO). The Funds are registered under the Investment Company Act of 1940, as amended, as closed-end management investment companies. Each Fund seeks to provide a high level of current income by investing primarily in senior loans whose interest rates float or adjust periodically based on a benchmark interest rate index. The following is a summary of significant accounting policies followed by the Funds in the preparation of their financial statements in accordance with U.S. generally accepted accounting principles. Investment Valuation The prices of senior loans, bonds and other securities in the Funds' investment portfolios, other than subordinated loans issued by middle market companies, are generally provided by one or more independent pricing services approved by the Funds' Board of Trustees. Floating Rate Income Opportunity (JRO) currently expects that the independent pricing services will be unable to provide a market based price for certain of the privately negotiated subordinated loans issued by middle market companies. The pricing services, with input from Symphony Asset Management, LLC ("Symphony"), an indirect wholly owned subsidiary of Nuveen, and Nuveen Asset Management (the "Adviser"), a wholly owned subsidiary of Nuveen, will estimate the fair value for such subordinated loans, subject to the supervision of Symphony and the Adviser. Floating Rate Income Opportunity (JRO) may engage an independent appraiser to periodically provide an independent determination of the value, or an opinion with respect to the pricing services' value, of such loans. The pricing services typically value exchange-listed securities at the last sales 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 asked prices when current quotations are readily available. The pricing services or, in the absence of a pricing service for a particular investment, the Board of Trustees of the Funds, or its designee, may establish fair market value using a wide variety of market data including yields or prices of investments of comparable quality, type of issue, coupon, maturity and rating, market quotes or indications of value from security dealers, evaluations of anticipated cash flows or collateral, general market conditions and other information and analysis, including the obligor's credit characteristics considered relevant by the pricing service or the Board of Trustees' designee. Short-term investments are valued at amortized cost, which approximates market value. The senior and subordinated loans in which the Funds invest are not listed on an organized exchange and the secondary market for such investments may be less liquid relative to markets for other fixed income securities. Consequently, the value of senior and subordinated loans, determined as described above, may differ significantly from the value that would have been determined had there been an active market for that loan. Investment Transactions Investment transactions are recorded on a trade date basis. Trade date for senior and subordinated loans purchased in the "primary market" is considered the date on which the loan allocations are determined. Trade date for senior and subordinated loans purchased in the "secondary market" is the date on which the transaction is entered into. 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 Funds maintain liquid assets with a current value at least equal to the amount of the when-issued/delayed delivery purchase commitments. At July 31, 2006, Senior Income (NSL), Floating Rate Income (JFR) and Floating Rate Income Opportunity (JRO) had outstanding when-issued/delayed delivery purchase commitments of $11,542,977, $16,709,987 and $12,412,749, respectively. Investment Income Dividend income is recorded on the ex-dividend date. Interest income, which includes the amortization of premiums and accretion of discounts for financial reporting purposes, is recorded on an accrual basis. Interest income also includes paydown gains and losses on senior and subordinated loans. Fee income, if any, consists primarily of amendment fees. Amendment fees are earned as compensation for evaluating and accepting changes to the original loan agreement and are recognized when received. 35 Notes to FINANCIAL STATEMENTS (continued) Professional Fees Professional fees presented in the Statement of Operations consist of legal fees incurred in the normal course of operations, audit fees, tax consulting fees and, in some cases, workout expenditures. Workout expenditures are incurred in an attempt to protect or enhance an investment, or to pursue other claims or legal actions on behalf of Fund shareholders. Federal Income Taxes Each Fund is a separate taxpayer for federal income tax purposes. Each Fund intends to distribute substantially all net investment income and net capital gains to shareholders and to otherwise comply with the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies. Therefore, no federal income tax provision is required. Dividends and Distributions to Common Shareholders Distributions to Common shareholders 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 U.S. generally accepted accounting principles. Each Fund declares 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. Preferred Shares Senior Income (NSL) has issued and outstanding 1,840 shares of Series TH, Taxable Auctioned Preferred shares, $25,000 stated value per share, as a means of effecting financial leverage. The dividend rate paid by the Fund is determined every 28 days, pursuant to a dutch auction process overseen by the auction agent, and is payable at the end of each rate period. Senior Income (NSL) has also effected financial leverage by borrowing, as described in footnote 8. Floating Rate Income (JFR) has issued and outstanding 4,000 shares of each Series M, T, W and F, FundPreferred shares, $25,000 stated value per share, as a means of effecting financial leverage. The dividend rate paid by the Fund is determined every seven days, pursuant to a dutch auction process overseen by the auction agent, and is payable at the end of each rate period. Floating Rate Income Opportunity (JRO) issued 3,200 shares of each Series M, TH and F, FundPreferred shares, $25,000 stated value per share, as a means of effecting financial leverage. The dividend rate paid by the Fund is determined every seven days, pursuant to a dutch auction process overseen by the auction agent, and is payable at the end of each rate period. Select Aggregate Market Index Floating Rate Income (JFR) and Floating Rate Income Opportunity (JRO) may invest in Select Aggregate Market Indexes ("SAMI") to synthetically increase their exposure to the senior secured loan market during a period when the Funds otherwise would have excess uninvested cash. The SAMI is designed to replicate the performance and risk of the CSFB Leveraged Loan Index. An investment in a SAMI, when combined with high-grade short-term investments such as repurchase agreements related to U.S. government securities in an amount equal to the notional amount of the SAMI, is designed to provide an aggregate return equivalent to an investment in a basket of senior secured bank loan debt ("Reference Obligations"), less certain costs. Upon entering into a SAMI, the Funds may pay the counterparty a premium based on the notional amount. The premium, if any, will be amortized over the life of the SAMI and recorded in "Other assets" in the Statement of Assets and Liabilities. The Funds will receive from the counterparty a fixed-rate interest payment based on the notional amount of the contract. In exchange for the interest payment, the Funds protect the counterparty from the risk of loss at the time of a credit event, such as a bankruptcy or default, affecting any of the Reference Obligations. Interest is recorded on an accrual basis and included in the Statement of Operations. The Funds are required to provide collateral to the counterparty based on a percentage of the notional amount of the SAMI and has instructed the custodian to segregate liquid assets with a current value at least equal to the remaining notional amount of the SAMI. The SAMI is valued daily and any change in value is recorded in "Change in net unrealized appreciation (depreciation) of SAMI." Upon termination of a SAMI, net realized gain (loss) is recorded in "Net realized gain (loss) from SAMI." Although there are economic advantages of entering into SAMI transactions, there are also additional risks, including but not limited to senior loan credit risk and the inability of the counterparty to meet its interest payment obligations. JFR did not hold any SAMI positions as of July 31, 2006. 36 Repurchase Agreements In connection with transactions in repurchase agreements, it is the Funds' 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 Each Fund has an arrangement with the custodian bank whereby certain custodian fees and expenses are reduced by credits earned on the Funds' cash on deposit with the bank. Such deposit arrangements are an alternative to overnight investments. Organization and Offering Costs Nuveen Investments, LLC agreed to reimburse all organization expenses (approximately $11,500 per Fund) and pay all Common share offering costs (other than the sales load) that exceeded $.03 per Common share for Floating Rate Income (JFR) and Floating Rate Income Opportunity (JRO). Floating Rate Income's (JFR) and Floating Rate Income Opportunity's (JRO) share of Common share offering costs ($1,066,755 and $814,831, respectively) were recorded as reductions of the proceeds from the sale of Common shares. Costs incurred by Floating Rate Income (JFR) and Floating Rate Income Opportunity (JRO) in connection with their offering of FundPreferred shares ($8,343,597 and $5,108,237, respectively) were recorded as a reduction to paid-in surplus. Indemnifications Under the Funds' organizational documents, their Officers and Trustees are indemnified against certain liabilities arising out of the performance of their duties to the Funds. In addition, in the normal course of business, the Funds enter into contracts that provide general indemnifications to other parties. The Funds' maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Funds that have not yet occurred. However, the Funds have not had prior claims or losses pursuant to these contracts and expect the risk of loss to be remote. Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles 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.

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, timing differences in recognizing certain gains and losses on investment transactions and for Floating Rate Income (JFR) and Floating Rate Income Opportunity (JRO) recognition of premium amortization. To the extent that differences arise that are permanent in nature, such amounts are reclassified within the capital accounts on the Statement of Assets and Liabilities, based on their Federal tax basis treatment and have no impact on the net asset value of the Funds. Temporary differences do not require reclassification. At July 31, 2006, the cost of investments was as follows: FLOATING FLOATING RATE SENIOR RATE INCOME INCOME INCOME OPPORTUNITY (NSL) (JFR) (JRO) -------------------------------------------------------------------------------------------------------------------- Cost of investments $410,751,914 $1,067,967,343 $634,689,501 -------------------------------------------------------------------------------------------------------------------- Gross unrealized appreciation and gross unrealized depreciation of investments at July 31, 2006, were as follows: FLOATING FLOATING RATE SENIOR RATE INCOME INCOME INCOME OPPORTUNITY (NSL) (JFR) (JRO) -------------------------------------------------------------------------------------------------------------------- Gross unrealized: Appreciation $3,210,778 $4,516,260 $3,353,155 Depreciation (13,557,367) (9,540,126) (3,610,632) -------------------------------------------------------------------------------------------------------------------- Net unrealized appreciation (depreciation) of investments $(10,346,589) $(5,023,866) $(257,477) -------------------------------------------------------------------------------------------------------------------- The tax components of undistributed net ordinary income and net long-term capital gains at July 31, 2006, were as follows: FLOATING FLOATING RATE SENIOR RATE INCOME INCOME INCOME OPPORTUNITY (NSL) (JFR) (JRO) -------------------------------------------------------------------------------------------------------------------- Undistributed net ordinary income * $3,178,033 $7,665,614 $4,596,621 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. Undistributed net ordinary income (on a tax basis) has not been reduced for the dividend declared on July 3, 2006, paid on August 1, 2006. The tax character of distributions paid during the tax years ended July 31, 2006 and July 31, 2005, was designated for purposes of the dividends paid deduction as follows: FLOATING FLOATING RATE SENIOR RATE INCOME INCOME INCOME OPPORTUNITY 2006 (NSL) (JFR) (JRO) -------------------------------------------------------------------------------------------------------------------- Distributions from net ordinary income * $20,471,502 $62,698,822 $38,562,840 Distributions from net long-term capital gains ** -- -- -- -------------------------------------------------------------------------------------------------------------------- 38 FLOATING FLOATING RATE SENIOR RATE INCOME INCOME INCOME OPPORTUNITY 2005 (NSL) (JFR) (JRO) -------------------------------------------------------------------------------------------------------------------- Distributions from net ordinary income * $18,143,299 $49,780,115 $26,710,473 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. ** The Funds designated as a long-term capital gain dividend, pursuant to the Internal Revenue Code Section 852(b)(3), the amount necessary to reduce the earnings and profits of the Funds related to net capital gain to zero for the tax year ended July 31, 2006. At July 31, 2006, the Funds had unused capital loss carryforwards available for federal income tax purposes to be applied against future capital gains, if any. If not applied, the carryforwards will expire as follows: FLOATING FLOATING RATE SENIOR RATE INCOME INCOME INCOME OPPORTUNITY (NSL) (JFR) (JRO) -------------------------------------------------------------------------------------------------------------------- Expiration year: 2010 $14,867,781 $ -- $ -- 2011 10,704,255 -- -- 2012 -- -- -- 2013 -- 819,145 30,377 2014 -- 2,934,270 2,151,577 -------------------------------------------------------------------------------------------------------------------- Total $25,572,036 $3,753,415 $2,181,954 -------------------------------------------------------------------------------------------------------------------- The following Funds elected to defer net realized losses from investments incurred from November 1, 2005 through July 31, 2006 ("post-October losses") in accordance with Federal income tax regulations. Post-October losses were treated as having arisen on the first day of the following tax year. FLOATING FLOATING RATE SENIOR RATE INCOME INCOME INCOME OPPORTUNITY (NSL) (JFR) (JRO) -------------------------------------------------------------------------------------------------------------------- $585,890 $4,668,296 $3,999,658 -------------------------------------------------------------------------------------------------------------------- 5. MANAGEMENT FEES AND OTHER TRANSACTIONS WITH AFFILIATES Each Fund's management fee is separated into two components - a complex-level component, based on the aggregate amount of all fund assets managed by Nuveen Asset Management (the "Adviser"), a wholly owned subsidiary of Nuveen Investments, Inc. ("Nuveen"), and a specific fund-level component, based only on the amount of assets within each individual fund. This pricing structure enables Nuveen fund shareholders to benefit from growth in the assets within each individual fund as well as from growth in the amount of complex-wide assets managed by the Adviser. The annual fund-level fee, payable monthly, for each Fund is based upon the average daily Managed Assets of each Fund as follows: SENIOR INCOME (NSL) AVERAGE DAILY MANAGED ASSETS FUND-LEVEL FEE RATE -------------------------------------------------------------------------------------------------------------- For the first $1 billion .6500% For the next $1 billion .6375 For the next $3 billion .6250 For the next $5 billion .6000 For Managed Assets over $10 billion .5750 -------------------------------------------------------------------------------------------------------------- FLOATING RATE INCOME (JFR) FLOATING RATE INCOME OPPORTUNITY (JRO) AVERAGE DAILY MANAGED ASSETS FUND-LEVEL FEE RATE -------------------------------------------------------------------------------------------------------------- For the first $500 million .6500% For the next $500 million .6250 For the next $500 million .6000 For the next $500 million .5750 For Managed Assets over $2 billion .5500 -------------------------------------------------------------------------------------------------------------- 39 Notes to FINANCIAL STATEMENTS (continued) The annual complex-level fee, payable monthly, which is additive to the fund-level fee, for all Nuveen sponsored funds in the U.S., is based on the aggregate amount of total fund assets managed as stated in the table below. As of July 31, 2006, the complex-level fee was .1875%. COMPLEX-LEVEL ASSETS(1) COMPLEX-LEVEL FEE RATE ---------------------------------------------------------------------------------------- For the first $55 billion .2000% For the next $1 billion .1800 For the next $1 billion .1600 For the next $3 billion .1425 For the next $3 billion .1325 For the next $3 billion .1250 For the next $5 billion .1200 For the next $5 billion .1175 For the next $15 billion .1150 For Managed Assets over $91 billion (2) .1400 ---------------------------------------------------------------------------------------- (1) The complex-level fee component of the management fee for the funds is calculated based upon the aggregate Managed Assets ("Managed Assets" means the average daily net assets of each fund including assets attributable to all types of leverage used by the Nuveen funds) of Nuveen-sponsored funds in the U.S. (2) With respect to the complex-wide Managed Assets over $91 billion, the fee rate or rates that will apply to such assets will be determined at a later date. In the unlikely event that complex-wide Managed Assets reach $91 billion prior to a determination of the complex-level fee rate or rates to be applied to Managed Assets in excess of $91 billion, the complex-level fee rate for such complex-wide Managed Assets shall be .1400% until such time as a different rate or rates is determined. The management fee compensates the Adviser for overall investment advisory and administrative services and general office facilities. The Adviser has entered into Sub-Advisory Agreements with Symphony under which Symphony manages the investment portfolio of the Funds. Symphony is compensated for its services to the Funds from the management fee paid to the Adviser. The Funds pay 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 Funds from the Adviser or its affiliates. The Board of Trustees has adopted a deferred compensation plan for independent Trustees that enables Trustees to elect to defer receipt of all or a portion of the annual compensation they are entitled to receive from certain Nuveen advised Funds. Under the plan, deferred amounts are treated as though equal dollar amounts had been invested in shares of select Nuveen advised Funds. For the first ten years of Senior Income's (NSL) operations, the Adviser has agreed to reimburse the Fund, as a percentage of average daily Managed Assets, for fees and expenses in the amounts and for the time periods set forth below: YEAR ENDING YEAR ENDING OCTOBER 31, OCTOBER 31, --------------------------------------------------------------------------------------- 1999 * .45% 2005 .35% 2000 .45 2006 .25 2001 .45 2007 .15 2002 .45 2008 .10 2003 .45 2009 .05 2004 .45 --------------------------------------------------------------------------------------- * From the commencement of operations. 40 The Adviser has not agreed to reimburse Senior Income (NSL) for any portion of its fees and expenses beyond October 31, 2009. For the first eight years of Floating Rate Income's (JFR) operations, the Adviser has agreed to reimburse the Fund, as a percentage of average daily Managed Assets, for fees and expenses in the amounts and for the time periods set forth below: YEAR ENDING YEAR ENDING MARCH 31, MARCH 31, --------------------------------------------------------------------------------------- 2004 * .32% 2009 .32% 2005 .32 2010 .24 2006 .32 2011 .16 2007 .32 2012 .08 2008 .32 --------------------------------------------------------------------------------------- * From the commencement of operations. The Adviser has not agreed to reimburse Floating Rate Income (JFR) for any portion of its fees and expenses beyond March 31, 2012. For the first eight years of Floating Rate Income Opportunity's (JRO) operations, the Adviser has agreed to reimburse the Fund, as a percentage of average daily Managed Assets, for fees and expenses in the amounts and for the time periods set forth below: YEAR ENDING YEAR ENDING JULY 31, JULY 31, --------------------------------------------------------------------------------------- 2004 * .30% 2009 .30% 2005 .30 2010 .22 2006 .30 2011 .14 2007 .30 2012 .07 2008 .30 --------------------------------------------------------------------------------------- * From the commencement of operations. The Adviser has not agreed to reimburse Floating Rate Income Opportunity (JRO) for any portion of its fees and expenses beyond July 31, 2012. 6. COMMITMENTS Pursuant to the terms of certain of the variable rate senior loan agreements, the Funds may have unfunded senior loan commit-ments. Each Fund will maintain with the 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 July 31, 2006, Senior Income (NSL), Floating Rate Income (JFR) and Floating Rate Income Opportunity (JRO) had unfunded senior loan commitments of $3,218,249, $4,592,281 and $5,489,301, respectively. 7. SENIOR LOAN PARTICIPATION COMMITMENTS With respect to the senior loans held in each Fund's portfolio, the Funds may: 1) invest in assignments; 2) act as a participant in primary lending syndicates; or 3) invest in participations. If a 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, rather than directly with the Borrower. As such, the Fund not only assumes the credit risk of the Borrower, but also that of the Selling Participant or other persons interpositioned between the Fund and the Borrower. Senior Income (NSL) had the following participation commitments outstanding at July 31, 2006: COMMITMENT COUNTERPARTY AMOUNT VALUE ------------------------------------------------------------------------------------------------------- Bear, Stearns & Co., Inc. $2,000,000 $1,898,043 Morgan Stanley 1,640,000 1,556,395 ------------------------------------------------------------------------------------------------------- Floating Rate Income (JFR) and Floating Rate Income Opportunity (JRO) had no such participation commitments outstanding at July 31, 2006. 8. BORROWINGS In accordance with Senior Income's (NSL) 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. Senior Income (NSL) has entered into a commercial paper program ($110 million maximum) 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 makes advances to Senior Income (NSL) and to many other borrowers who comprise Falcon's total borrowing base. For the fiscal year ended July 31, 2006, the average daily balance of borrowings under the commercial paper program agreement was $103 million. The average annualized interest rate for funding and program usage fees on such borrowings was 4.50%. 41 Notes to FINANCIAL STATEMENTS (continued) Senior Income (NSL) 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 fiscal year ended July 31, 2006. 9. NEW ACCOUNTING PRONOUNCEMENT Financial Accounting Standards Board Interpretation No. 48 On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB Interpretation No. 48 Accounting for Uncertainty in Income Taxes (FIN 48). FIN 48 provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. At this time, management is evaluating the implications of FIN 48 and does not expect the adoption of FIN 48 will have a significant impact on the net assets or results of operations of the Funds. 10. SUBSEQUENT EVENT Distributions to Common Shareholders The Funds declared Common share dividend distributions from their net investment income which was paid on September 1, 2006, to shareholders of

At a meeting held on May 23-25, 2006 (the "May Meeting"), the Board of Trustees of the Funds, including the independent Trustees, unanimously approved the continuance of the Investment Management Agreement between each Fund and NAM and the Sub-Advisory Agreement between NAM and Symphony (the "Sub-Adviser"). NAM and the Sub-Adviser are each a "Fund Adviser." THE APPROVAL PROCESS During the course of the year, the Board received a wide variety of materials relating to the services provided by the Fund Advisers and the performance of each Fund. To assist the Board in its evaluation of the advisory contract with a Fund Adviser at the May Meeting, the independent Trustees received extensive materials in advance of their meeting which outlined, among other things: - the nature, extent and quality of services provided by the Fund Adviser; - the organization and business operations of the Fund Adviser, including the responsibilities of various departments and key personnel; - the Fund's past performance, the Fund's performance compared to funds of similar investment objectives compiled by an independent third party and with recognized and/or customized benchmarks (as appropriate); - the profitability of the Fund Adviser and certain industry profitability analyses for unaffiliated advisers; - the expenses of the Fund Adviser in providing the various services; - the advisory fees (gross and net management fees) and total expense ratios of the Fund, including comparisons of such fees and expenses with those of comparable, unaffiliated funds based on information and data provided by Lipper (the "Peer Universe") as well as compared to a subset of funds within the Peer Universe (the "Peer Group") to the respective Fund (as applicable); - the advisory fees the Fund Adviser assesses to other types of investment products or clients; - the soft dollar practices of the Fund Adviser, if any; and - from independent legal counsel, a legal memorandum describing, among other things, the duties of the Trustees under the Investment Company Act of 1940 (the "1940 Act") as well as the general principles of relevant state law in reviewing and approving advisory contracts; the requirements of the 1940 Act in such matters; an adviser's fiduciary duty with respect to advisory agreements and compensation; the standards used by courts in determining whether investment company boards of directors have fulfilled their duties; and factors to be considered by the Board in voting on advisory agreements. At the May Meeting, NAM made a presentation to and responded to questions from the Board. After the presentations and after reviewing the written materials, the independent Trustees met privately with their legal counsel to review the Board's duties in reviewing advisory contracts and consider the renewal of the advisory contracts. It is with this background that the Trustees considered each advisory contract (which includes the Sub-Advisory Agreements) with the respective Fund Adviser. The independent Trustees, in consultation with independent counsel, reviewed the factors set out in judicial decisions and SEC directives relating to the renewal of advisory contracts. As outlined in more detail below, the Trustees considered all factors they believed relevant with respect to each Fund, including the following: (a) the nature, extent and quality of the services to be provided by the Fund Adviser; (b) the investment performance of the Fund and the Fund Adviser; (c) the costs of the services to be provided and profitability of the Fund Adviser and its affiliates; (d) the extent to which economies of scale would be realized as the Fund grows; and (e) whether fee levels reflect these economies of scale for the benefit of Fund investors. A. NATURE, EXTENT AND QUALITY OF SERVICES In reviewing the Fund Advisers, the Trustees considered the nature, extent and quality of the respective Fund Adviser's services. The Trustees reviewed materials outlining, among other things, the Fund Adviser's organization and business; the types of services that the Fund Adviser or its affiliates provide and are expected to provide to the Funds; the performance record of the applicable Fund (as described in further detail below); and any initiatives Nuveen has taken for its fund product line. In connection with their continued service as Trustees, the Trustees also have a good understanding of each Fund Adviser's organization, operations and personnel. In this regard, the Trustees are familiar with and have evaluated the professional experience, qualifications and credentials of the Fund Adviser's personnel. With respect to the Sub-Adviser, the Trustees also received and reviewed an evaluation of the Sub-Adviser from NAM. Such evaluation outlined, among other things, the Sub-Adviser's organizational history, 50 client base, product mix, investment team and any changes thereto, investment process and any changes to its investment strategy, the Fund's investment objectives and performance (as applicable). The Trustees noted that NAM recommended the renewal of the Sub-Advisory Agreements and considered the basis for such recommendation and any qualifications in connection therewith. Given the Trustees' experience with the Funds (including any other Nuveen funds advised by a Fund Adviser) and each Fund Adviser, the Trustees recognized and considered the quality of their investment processes in making portfolio management decisions as well as any refinements or improvements thereto. In this regard, the Trustees considered the continued quality of the Fund Adviser's investment process in making portfolio management decisions as well as any additional refinements and improvements adopted to the portfolio management processes. In addition to advisory services, the independent Trustees considered the quality of any administrative or non-advisory services provided. With respect to the Sub-Adviser, the independent Trustees noted that the Sub-Advisory Agreements were essentially agreements for portfolio management services only and the Sub-Adviser was not expected to supply other significant administrative services to the Funds. With respect to NAM, NAM provides the Funds with such administrative and other services (exclusive of, and in addition to, any such services provided by others for the Funds) and officers and other personnel as are necessary for the operations of the respective Fund. In connection with the review of the Investment Management Agreement, the Trustees considered the extent and quality of these other services which include, among other things, providing: product management (e.g., product positioning, performance benchmarking, risk management); fund administration (e.g., daily net asset value pricing and reconciliation, tax reporting, fulfilling regulatory filing requirements); oversight of third party service providers; administration of board relations (e.g., organizing board meetings and preparing related materials); compliance (e.g., monitoring compliance with investment policies and guidelines and regulatory requirements); and legal support (e.g., helping prepare and file registration statements, amendments thereto, proxy statements and responding to regulatory requests and/or inquiries). As the Funds operate in a highly regulated industry and given the importance of compliance, the Trustees considered, in particular, the additions of experienced personnel to the compliance teams and the enhancements to technology and related systems to support the compliance activities for the Funds (including a new reporting system for quarterly portfolio holdings). In addition to the above, because the Funds utilize a Sub-Adviser, the Trustees also considered NAM's ability and procedures to monitor the Sub-Adviser's performance, business practices and compliance policies and procedures. In this regard, the Trustees noted the enhancements in the investment oversight process, including increased site visits and departments participating in investment oversight. In addition to the foregoing, the Trustees also noted the additional services that the Fund Adviser or its affiliates provide to closed-end funds, including, in particular, secondary market support activities. The Trustees recognized Nuveen's continued commitment to supporting the secondary market for the common shares of its closed-end funds through a variety of initiatives designed to raise investor and analyst awareness and understanding of closed-end funds. These efforts include providing advertising and other media relations programs, continued contact with analysts, maintaining and enhancing its website for closed-end funds, and targeted advisor communication programs. With respect to Funds that utilize leverage through the issuance of preferred shares, the Trustees noted Nuveen's continued support for the preferred shares by maintaining, among other things, an in-house preferred trading desk; designating a product manager whose responsibilities include creating and disseminating product information and managing relations in connection with the preferred share auction; and maintaining systems necessary to test compliance with rating agency requirements. Based on their review, the Trustees found that, overall, the nature, extent and quality of services provided (and expected to be provided) to the respective Funds under the Investment Management Agreement or Sub-Advisory Agreement, as applicable, were of a high level and were satisfactory. B. THE INVESTMENT PERFORMANCE OF THE FUND AND FUND ADVISERS The Board considered the investment performance for each Fund, including the Fund's historic performance as well as its performance compared to funds with similar investment objectives identified by an independent third party (the "Performance Peer Group") and recognized and/or customized benchmarks (as applicable). In evaluating the performance information, in certain instances, the Trustees noted that the closest Performance Peer Group for a Fund still may not adequately reflect such Fund's investment objectives, strategies and portfolio duration, thereby limiting the usefulness of the comparisons of such Fund's performance with that of the Performance Peer Group (such as, the Nuveen Diversified Dividend and Income Fund, Nuveen Preferred and Convertible Income Fund, Nuveen Preferred and Convertible Income Fund 2, Nuveen Tax-Advantaged Floating Rate Fund, and Nuveen Real Estate Income Fund). In reviewing performance, the Trustees reviewed performance information including, among other things, total return information compared with the Fund's Performance Peer Group as well as recognized and/or customized benchmarks (as appropriate) for the one-, three- and five-year periods (as applicable) ending December 31, 2005. This information supplements the Fund performance information provided to the Board at each of their quarterly meetings. Based on their review, the Trustees determined that the respective Fund's absolute and relative investment performance over time had been satisfactory. C. FEES, EXPENSES AND PROFITABILITY 1. FEES AND EXPENSES In evaluating the management fees and expenses of a Fund, the Board reviewed, among other things, the Fund's advisory fees (net and gross management fees) and total expense ratios (before and after expense reimbursements and/or waivers) in absolute terms as well as comparisons to the gross management fees (before waivers), net management fees (after waivers) and total expense ratios (before and after waivers) of comparable funds in the Peer Universe and the Peer Group. The Trustees reviewed data regarding the construction of Peer Groups as well as the methods of measurement for the fee and expense 51 Annual Investment MANAGEMENT AGREEMENT APPROVAL PROCESS (continued) analysis and the performance analysis. In certain cases, due to the small number of peers in the Peer Universe, the Peer Universe and the Peer Group may be the same. Further, the Trustees recognized that in certain cases the closest Peer Universe and/or Peer Group may not adequately reflect the Fund's investment objectives and strategies limiting the usefulness of comparisons. In reviewing comparisons, the Trustees also considered the size of the Peer Universe and/or Peer Group, the composition of the Peer Group (including differences in the use of leverage) as well as differing levels of fee waivers and/or expense reimbursements. In this regard, the Trustees considered the fund-level and complex-wide breakpoint schedules (described in further detail below) and any fee waivers and reimbursements provided by Nuveen (applicable, in particular, for certain funds launched since 1999). Based on their review of the fee and expense information provided, the Trustees determined that each Fund's net total expense ratio was within an acceptable range compared to peers. 2. COMPARISONS WITH THE FEES OF OTHER CLIENTS The Trustees further reviewed data comparing the advisory fees of NAM with fees NAM charges to other clients (such as separate managed accounts and funds that are not offered by Nuveen Investments but are sub-advised by one of Nuveen's investment management teams). In general, the advisory fees charged for separate accounts are somewhat lower than the advisory fees assessed to the Funds. The Trustees recognized that the differences in fees are attributable to a variety of factors, including the differences in services provided, product distribution, portfolio investment policies, investor profiles, account sizes and regulatory requirements. The Trustees noted, in particular, that the range of services provided to the Funds is more extensive than that provided to managed separate accounts. As described in further detail above, such additional services include, but are not limited to, providing: product management, fund administration, oversight of third party service providers, administration of board relations, and legal support. Funds further operate in a highly regulated industry requiring extensive compliance functions compared to the other investment products. In addition to the costs of the additional services, administrative costs may also be greater for funds as the average account size for separate accounts is notably larger than the retail accounts of funds. Given the differences in the product structures, particularly the extensive services provided to closed-end funds, the Trustees believe such facts justify the different levels of fees. In considering the advisory fees of the Sub-Adviser, the Trustees also considered the pricing schedule that the Sub-Adviser charges for similar investment management services for other sponsors or clients. With respect to Symphony, the Trustees reviewed the generally higher fees for hedge funds and accounts it manages, which includes performance fees. 3. PROFITABILITY OF FUND ADVISERS In conjunction with its review of fees, the Trustees also considered the profitability of Nuveen Investments for advisory activities (which incorporated Nuveen's wholly-owned affiliated sub-advisers). The Trustees reviewed data comparing Nuveen's profitability with other fund sponsors prepared by three independent third party service providers as well as comparisons of the revenues, expenses and profits margins of various unaffiliated management firms with similar amounts of assets under management prepared by Nuveen. The Trustees further reviewed the 2005 Annual Report for Nuveen Investments. In considering profitability, the Trustees recognized the inherent limitations in determining profitability as well as the difficulties in comparing the profitability of other unaffiliated advisers. Profitability may be affected by numerous factors, including the methodology for allocating expenses, the adviser's business mix, the types of funds managed, the adviser's capital structure and cost of capital. Further, individual fund or product line profitability of other sponsors is generally not publicly available. Accordingly, the profitability information that is publicly available from various investment advisory or management firms may not be representative of the industry. Notwithstanding the foregoing, in reviewing profitability, the Trustees reviewed Nuveen's methodology and assumptions for allocating expenses across product lines to determine profitability. In this regard, the methods of allocation used appeared reasonable. The Trustees also, to the extent available, compared Nuveen's profitability margins (including pre- and post-marketing profit margins) with the profitability of various unaffiliated management firms. The Trustees noted that Nuveen's profitability is enhanced due to its efficient internal business model. The Trustees also recognized that while a number of factors affect profitability, Nuveen's profitability may change as fee waivers and/or expense reimbursement commitments of Nuveen to various funds in the Nuveen complex expire. To keep apprised of profitability and developments that may affect profitability, the Trustees have requested profitability analysis be provided periodically during the year. Based on their review, the Trustees were satisfied that the level of profitability was reasonable in light of the services provided. In evaluating the reasonableness of the compensation, the Trustees also considered any other revenues paid to a Fund Adviser as well as any indirect benefits (such as soft dollar arrangements, if any) the Fund Adviser and its affiliates are expected to receive that are directly attributable to their management of the Funds, if any. See Section E below for additional information. Based on 52 their review of the overall fee arrangements of the applicable Fund, the Trustees determined that the advisory fees and expenses of the respective Fund were reasonable. D. ECONOMIES OF SCALE AND WHETHER FEE LEVELS REFLECT THESE ECONOMIES OF SCALE With respect to economies of scale, the Trustees recognized the potential benefits resulting from the costs of a fund being spread over a larger asset base as a fund grows. To help ensure the shareholders share in these benefits, the Trustees have reviewed and considered the breakpoints in the advisory fee schedules that reduce advisory fees as the applicable Fund's assets grow. In addition to advisory fee breakpoints as assets in a respective Fund rise, after lengthy discussions with management, the Board also approved a complex-wide fee arrangement that was introduced on August 1, 2004. Pursuant to the complex-wide fee arrangement, the fees of the funds in the Nuveen complex, including the Funds, are reduced as the assets in the fund complex reach certain levels. In evaluating the complex-wide fee arrangement, the Trustees considered, among other things, the historic and expected fee savings to shareholders as assets grow, the amount of fee reductions at various asset levels, and that the arrangement would extend to all funds in the Nuveen complex. The Trustees noted that 2005 was the first full year to reflect the fee reductions from the complex wide fee arrangement. The Trustees also considered the impact, if any, the complex-wide fee arrangement may have on the level of services provided. Based on their review, the Trustees concluded that the breakpoint schedule and complex-wide fee arrangement currently was acceptable and desirable in providing benefits from economies of scale to shareholders. E. INDIRECT BENEFITS In evaluating fees, the Trustees also considered any indirect benefits or profits the Fund Adviser or its affiliates may receive as a result of its relationship with each Fund. In this regard, the Trustees considered revenues received by affiliates of the Fund Adviser for serving as agent at Nuveen's preferred trading desk and for serving as a co-manager in the initial public offering of new closed-end exchange traded funds. In addition to the above, the Trustees considered whether the Fund Adviser received any benefits from soft dollar arrangements. With respect to NAM, the Trustees noted that NAM does not currently have any soft dollar arrangements and does not pay excess brokerage commissions (or spreads on principal transactions) in order to receive research services; however, NAM may from time to time receive and have access to research generally provided to institutional clients. The Trustees also considered the soft dollar arrangements, if any, of the Sub-Adviser. With respect to Symphony, Symphony currently does not enter into soft dollar arrangements; however, it has adopted a soft dollar policy in the event it does so in the future. The Trustees did not identify any single factor discussed previously as all-important or controlling. The Trustees, including a majority of independent Trustees, concluded that the terms of the Investment Management Agreement and Sub-Advisory Agreements were fair and reasonable, that the respective Fund Adviser's fees are reasonable in light of the services provided to each Fund, and that the renewal of the respective Investment Management Agreement and Sub-Advisory Agreement should be approved. 53 Reinvest Automatically EASILY AND CONVENIENTLY NUVEEN EXCHANGE-TRADED CLOSED-END FUNDS DIVIDEND REINVESTMENT PLAN Your Nuveen Exchange-Traded Closed-End 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 NUVEEN MAKES REINVESTING EASY. A PHONE CALL IS ALL IT TAKES TO SET UP YOUR REINVESTMENT ACCOUNT. 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 the 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. FLEXIBLE 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. CALL TODAY TO START REINVESTING DIVIDENDS AND/OR DISTRIBUTIONS For more information on the Nuveen Automatic Reinvestment Plan or to enroll in or withdraw from the Plan, speak with your financial advisor or call us at (800) 257-8787. 54 AUTOMATIC DIVIDEND REINVESTMENT PLAN NOTICE OF AMENDMENT TO THE TERMS AND CONDITIONS These Funds are amending the terms and conditions of their Automatic Dividend Reinvestment Plan (the "Plan") as further described below effective with the close of business on December 1, 2006. THESE CHANGES ARE INTENDED TO ENABLE PLAN PARTICIPANTS UNDER CERTAIN CIRCUMSTANCES TO REINVEST FUND DISTRIBUTIONS AT A LOWER AGGREGATE COST THAN IS POSSIBLE UNDER THE EXISTING PLAN. Shareholders who do not wish to continue as participants under the amended Plan may withdraw from the Plan by notifying the Plan Agent prior to the effective date of the amendments. Participants should refer to their Plan document for notification instructions, or may simply call Nuveen at (800) 257-8787. Fund shareholders who elect to participate in the Plan are able to have Fund distributions consisting of income dividends, realized capital gains and returns of capital automatically reinvested in additional Fund shares. Under the Plan's existing terms, the Plan Agent purchases Fund shares in the open market if the Fund's shares are trading at a discount to their net asset value on the payable date for the distribution. If the Fund's shares are trading at or above their net asset value on the payable date for the distribution, the Plan Agent purchases newly-issued Fund shares directly from the Fund at a price equal to the greater of the shares' net asset value or 95% of the shares' market value. Under the Plan's amended terms, if the Plan Agent begins purchasing Fund shares on the open market while shares are trading below net asset value, but the Fund's shares subsequently trade at or above their net asset value before the Plan Agent is able to complete its purchases, the Plan Agent may cease open-market purchases and may invest the uninvested portion of the distribution in newly-issued Fund shares at a price equal to the greater of the shares' net asset value or 95% of the shares' market value. This change will permit Plan participants under these circumstances to reinvest Fund distributions at a lower aggregate cost than is possible under the existing Plan. 55 Notes 56 Notes 57 Notes 58 OTHER USEFUL INFORMATION QUARTERLY PORTFOLIO OF INVESTMENTS AND PROXY VOTING INFORMATION The Funds' (i) quarterly portfolio of investments, (ii) information regarding how the Funds voted proxies relating to portfolio securities held during the most recent 12-month period ended June 30, 2006, and (iii) a description of the policies and procedures that the Fund used to determine how to vote proxies relating to portfolio securities are available without charge, upon request, by calling Nuveen Investments toll-free at (800) 257-8787 or on Nuveen's website at www.nuveen.com.

CEO CERTIFICATION DISCLOSURE Each Fund's Chief Executive Officer has submitted to the New York Stock Exchange the annual CEO certification as required by Section 303A.12(a) of the NYSE Listed Company Manual. Each Fund has filed with the Securities and Exchange Commission the certification of its Chief Executive Officer and Chief Financial Officer required by Section 302 of the Sarbanes-Oxley Act. GLOSSARY OF TERMS USED IN THIS REPORT AVERAGE ANNUAL TOTAL RETURN: This is a commonly used method to express an investment's performance over a particular, usually multi-year time period. It expresses the return that would have been necessary each year to equal the investment's actual cumulative performance (including change in NAV or market price and reinvested dividends and capital gains distributions, if any) over the time period being considered. MARKET YIELD: Market yield is based on the Fund's current annualized monthly distribution divided by the Fund's current market price. The Fund's monthly distributions to its shareholders may be comprised of ordinary income, net realized capital gains and, if at the end of the calendar year the Funds' cumulative net ordinary income and net realized gains are less than the amount of the Fund's distributions, a tax return of capital. NET ASSET VALUE (NAV): A Fund's common share NAV per share is calculated by subtracting the liabilities of the Fund (including any MuniPreferred shares issued in order to leverage 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. BOARD OF TRUSTEES Robert P. Bremner Lawrence H. Brown Jack B. Evans William C. Hunter David J. Kundert William J. Schneider Timothy R.

[There were no amendments to or waivers from the Code during the period covered by this report.] The registrant has posted the code of ethics on its website at www.nuveen.com/etf. (To view the code, click on the Investor Resources drop down menu box, click on Fund Governance and then click on Code of Conduct.) ITEM 3. AUDIT COMMITTEE FINANCIAL EXPERT. The registrant's Board of Directors or Trustees determined that the registrant has at least one "audit committee financial expert" (as defined in Item 3 of Form N-CSR) serving on its Audit Committee. The registrant's audit committee financial expert is Jack B. Evans, Chairman of the Audit Committee, who is "independent" for purposes of Item 3 of Form N-CSR.

As part of his role as President and Chief Operating Officer, Mr. Evans actively supervised the Chief Financial Officer (the "CFO") and actively supervised the CFO's preparation of financial statements and other filings with various regulatory authorities. In such capacity, Mr. Evans was actively involved in the preparation of SCI's financial statements and the resolution of issues raised in connection therewith. Mr. Evans has also served on the audit committee of various reporting companies. At such companies, Mr. Evans was involved in the oversight of audits, audit plans, and the preparation of financial statements. Mr. Evans also formerly chaired the audit committee of the Federal Reserve Bank of Chicago. ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES. Nuveen Senior Income Fund The following tables show the amount of fees that Ernst & Young LLP, the Fund's auditor, billed to the Fund during the Fund's last two full fiscal years. For engagements with Ernst & Young LLP the Audit Committee approved in advance all audit services and non-audit services that Ernst & Young LLP provided to the Fund, except for those non-audit services that were subject to the pre-approval exception under Rule 2-01 of Regulation S-X (the "pre-approval exception"). The pre-approval exception for services provided directly to the Fund waives the pre-approval requirement for services other than audit, review or attest services if: (A) the aggregate amount of all such services provided constitutes no more than 5% of the total amount of revenues paid by the Fund to its accountant during the fiscal year in which the services are provided; (B) the Fund did not recognize the services as non-audit services at the time of the engagement; and (C) the services are promptly brought to the Audit Committee's attention, and the Committee (or its delegate) approves the services before the audit is completed. The Audit Committee has delegated certain pre-approval responsibilities to its Chairman (or, in his absence, any other member of the Audit Committee).

The tables also show the percentage of fees subject to the pre-approval exception. The pre-approval exception for services provided to the Adviser and any Affiliated Fund Service Provider (other than audit, review or attest services) waives the pre-approval requirement if: (A) the aggregate amount of all such services provided constitutes no more than 5% of the total amount of revenues paid to Ernst & Young LLP by the Fund, the Adviser and Affiliated Fund Service Providers during the fiscal year in which the services are provided that would have to be pre-approved by the Audit Committee; (B) the Fund did not recognize the services as non-audit services at the time of the engagement; and (C) the services are promptly brought to the Audit Committee's attention, and the Committee (or its delegate) approves the services before the Fund's audit is completed.

The Audit Committee requested and received information from Ernst & Young LLP about any non-audit services that Ernst & Young LLP rendered during the Fund's last fiscal year to the Adviser and any Affiliated Fund Service Provider. The Committee considered this information in evaluating Ernst & Young LLP's independence.

The members of the audit committee are Robert P. Bremner, Lawrence H. Brown, Jack B. Evans, William J. Schneider and Eugene S. Sunshine. ITEM 6. SCHEDULE OF INVESTMENTS. See Portfolio of Investments in Item 1. ITEM 7. DISCLOSURE OF PROXY VOTING POLICIES AND PROCEDURES FOR CLOSED-END MANAGEMENT INVESTMENT COMPANIES. The Adviser has engaged Symphony Asset Management, LLC ("Symphony"), an affiliate of the Adviser, as Sub-Adviser to provide discretionary investment advisory services. As part of these services, the Adviser has also delegated to the Sub-Adviser the full responsibility for proxy voting and related duties in accordance with the Sub-Adviser's policies and procedures. The Adviser will periodically monitor the Sub-Adviser's voting to ensure that the Sub-Adviser is carrying out its duties. The Sub-Adviser's proxy voting policies and procedures are summarized in the following paragraphs. Symphony uses the proxy voting services of Institutional Shareholder Services ("ISS"). The ISS Proxy Voting Services provide Symphony and its clients with an independent source of proxy voting research and services. The use of ISS is designed to offer client-centered proxy voting which minimizes conflicts of interests between Symphony's interests and those of its clients. In order to monitor how ISS votes client proxies, Symphony has established a Proxy Voting Review Committee (the "Committee"). The Committee is composed of Symphony's Chief Operating Officer and its Chief Investment Officer. Each year, the Committee reviews ISS proxy voting policies and practices to determine whether such policies and practices are consistent with Symphony's fiduciary duty to the clients for whom Symphony is responsible for voting proxies. During the year, the Committee reviews how ISS votes on specific issues. From time to time, the Committee discusses the proxy voting process with representatives of ISS in order to ensure that Symphony's client interests are being protected. When Symphony disagrees with ISS' policies with respect to certain issues, Symphony will direct the voting of its clients' proxies according to what Symphony believes is the best interests of its clients. Clients who have questions about how particular proxies are voted for their account may request such information from Symphony by calling (800) 847-6369. ITEM 8. PORTFOLIO MANAGERS OF CLOSED-END MANAGEMENT INVESTMENT COMPANIES. The Adviser has engaged Symphony Asset Management also referred to as "Sub-Adviser") as Sub-Adviser to provide discretionary investment advisory services. The following section provides information on the portfolio managers of the Sub-Adviser. SYMPHONY ASSET MANAGEMENT A. PORTFOLIO MANAGER BIOGRAPHIES Gunther Stein, Director of Fixed Income Strategies, Portfolio Manager Gunther Stein is the lead portfolio manager for high yield strategies at Symphony Asset Management and is the lead portfolio manager of Nuveen's senior loan asset management team. Prior to joining Symphony in 1999, Stein was a high yield portfolio manager at Wells Fargo Bank, where he was responsible for investing in public high yield bonds and bank loans and also managed a team of credit analysts. Stein joined Wells Fargo in 1993 as an Associate in its Loan Syndications/Leveraged Finance Group. Previously, Stein worked for four years as a euro-currency deposit trader with First Interstate Bank. He has also worked for Standard Chartered Bank, Mexico City and Citibank Investment Bank, London. He completed Wells Fargo's Credit Management Training program and holds an M.B.A. from the University of Texas, Austin. He graduated from the University of California at Berkeley with a B.A. in Economics. Lenny Mason, Portfolio Manager Lenny Mason is a high yield portfolio manager for Symphony Asset Management and is also a portfolio manager on the Nuveen's senior loan asset management team. Prior to joining Symphony in 2001, Mason was a Managing Director in FleetBoston's Technology & Communications Group, where he headed its five member Structuring and Advisory Team.

POTENTIAL MATERIAL CONFLICTS OF INTEREST As described above, the portfolio managers may manage other accounts with investment strategies similar to the Fund, including other investment companies and separately managed accounts. Fees earned by the Sub-adviser may vary among these accounts and the portfolio managers may personally invest in some but not all of these accounts. These factors could create conflicts of interest because a portfolio manager may have incentives to favor certain accounts over others, resulting in other accounts outperforming the Fund. A conflict may also exist if a portfolio manager identified a limited investment opportunity that may be appropriate for more than one account, but the Fund is not able to take full advantage of that opportunity due to the need to allocate that opportunity among multiple accounts. In addition, the portfolio managers may execute transactions for another account that may adversely impact the value of securities held by the Fund. However, the Sub-adviser believes that these risks are mitigated by the fact that accounts with like investment strategies managed by a particular portfolio manager are generally managed in a similar fashion, subject to exceptions to account for particular investment restrictions or policies applicable only to certain accounts, differences in cash flows and account sizes, and other factors. In addition, the Sub-adviser has adopted trade allocation procedures that require equitable allocation of trade orders for a particular security among participating accounts. D. FUND MANAGER COMPENSATION Symphony investment professionals receive competitive base salaries and participate in a bonus pool which is tied directly to the firm's operating income with a disproportionate amount paid to the managers responsible for generating the alpha. The bonus paid to investment personnel is based on acumen, overall contribution and strategy performance. However, there is no fixed formula which guides bonus allocations. Bonuses are paid on an annual basis. In addition, investment professionals may participate in an equity-based compensation pool. E.
