Schwertfeger Chairman of the Board Chairman's LETTER TO SHAREHOLDERS I am very pleased to report that over the six-month period covered by this report, your Fund continued to provide you with attractive monthly income 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, a senior loan investment like your Fund may help you achieve and benefit from greater portfolio diversification. Your financial advisor can explain these advantages in more detail. I encourage you to contact him or her for more information on this and other important investment strategies.

Schwertfeger Timothy R. Schwertfeger Chairman of the Board March 15, 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 six-month period ended January 31, 2006. WHAT STRATEGIES AND TACTICS DID YOU USE TO MANAGE THE FUNDS' ASSETS OVER THE COURSE OF THIS SIX-MONTH REPORTING PERIOD? Over this period, we continued to view the leveraged loan market favorably but, given the current credit environment, we continued to take a defensive stance in positioning the portfolios. The loan market continued to demonstrate many positive characteristics that we thought made the asset class attractive. Market liquidity was better than it had ever been, investor appetite remained strong and many high quality deals were coming to market. Strong investor demand, however, also allowed many deals to be structured with aggressive leverage levels. It was this environment and market dynamic that led us to avoid credits we felt were too aggressively leveraged or did not have a sound credit profile. We did not feel that it was the appropriate time to reach for yield or become involved with what we considered to be marginal credits. We continued to avoid 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 feel that market liquidity could be challenged if the credit experiences any negative events. We were 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. 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 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. 4 HOW DID THE FUNDS PERFORM? The performance of each Fund over the six-month period ended January 31, 2006, as well as the performance of a comparative index, is shown in the nearby chart. TOTAL RETURN ON NET ASSET VALUE For periods ended January 31, 2006* 6-MONTHS 1-YEAR 5-YEAR -------------------------------------------------------------------------------- NSL 2.82% 5.17% 6.99% -------------------------------------------------------------------------------- JFR 2.93% 5.58% NA -------------------------------------------------------------------------------- JRO 3.14% 6.08% NA -------------------------------------------------------------------------------- CSFB Leveraged Loan Index1 3.02% 5.83% 5.17% -------------------------------------------------------------------------------- * Six-month returns are cumulative; returns for one year and five years are annualized. Past performance does not guarantee future results. Currently 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 Performance Overview pages in this report. Over the six-month reporting period, JRO slightly outperformed the unmanaged, unleveraged CSFB Leveraged Loan Index. NSL and JFR slightly underperformed the CSFB index during this period. One of the primary factors benefiting the performance of all of these Funds over this reporting period relative to that of the CSFB index was the Funds' use of financial leverage. While leveraging can add volatility to a Fund's NAV and share price, this can also provide opportunities for additional income and total return for common shareholders when short-term interest rates paid by the Funds on their FundPreferred(R) shares are less than the returns the Funds are earning from the adjustable rate loans in their portfolios. As noted earlier, each Fund's portfolio was relatively defensive in nature, avoiding higher volatility areas like the automotive sector and second tier loans. In all three portfolios, the positions we held during the course of reporting period had relatively stable prices and delivered returns generally consistent with their coupons. 1 The CSFB Leveraged Loan Index is a representative, unmanaged index of tradable, senior, U.S. dollar-denominated leveraged loans. It is not possible to invest directly in an Index. 5 Each Fund had holdings that constrained the Fund's performance over this reporting period. In NSL, one issuer that had a negative impact on the portfolio was Primedia. The equity sponsors of the company proposed splitting it up into two smaller companies, and Primedia issues traded down as a result as questions arose about the company's ultimate capital structure and leverage. In JFR, issues from Georgia Pacific (which is now being acquired by Koch Industries) traded down after the announcement of the leveraged buyout. In JRO, Resorts International had a negative impact on the portfolio. 6 Dividend and Share Price INFORMATION As noted, 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 market interest rates. These rates generally were rising over this six-month reporting period, and this led to two monthly dividend increases in JFR and JRO. NSL maintained a stable dividend over this six-month period. All of these Funds seek to pay stable 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 January 31, 2006, NSL had a positive UNII balance for financial reporting purposes and a positive UNII balance, based on our best estimates, for tax purposes. As of January 31, 2006, JFR and JRO had negative UNII balances for financial reporting purposes and positive UNII balances, based on our best estimates, for tax purposes. As of January 31, 2006, the Funds' share prices were trading at discounts to their NAVs as shown in the accompanying chart: 6-MONTH 1/31/2006 PERIOD AVERAGE FUND DISCOUNT DISCOUNT -------------------------------------------------------------------------------- NSL -4.52% -3.08% -------------------------------------------------------------------------------- JFR -7.91% -8.31%

(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 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. (4) Ratings: Using the higher of Standard & Poor's or Moody's rating. Ratings below Baa by Moody's Investor Service, Inc. or BBB by Standard & Poor's Group are considered to be below investment grade. (5) Position represents an unfunded loan commitment outstanding at January 31, 2006. (6) Borrowings payable as a percentage of total investments is (25.4%). (7) At or subsequent to January 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 January 31, 2006. (10) Investment valued at fair value using methods determined in good faith by, or at the discretion of, the Board of Trustees. WI/DD Investment purchased on a when-issued or delayed delivery basis. DD1 Portion of investment purchased on a delayed delivery basis. N/R Investment is not rated. 144A Securities are exempt from registration under Rule 144A of the Securities Act of 1933, as amended. These securities 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 lien 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 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. (4) Ratings: Using the higher of Standard & Poor's or Moody's rating. Ratings below Baa by Moody's Investor Service, Inc. or BBB by Standard & Poor's Group are considered to be below investment grade. (5) Position represents an unfunded loan commitment outstanding at January 31, 2006. (6) At or subsequent to January 31, 2006, this issue was under the protection of the Federal Bankruptcy Court. WI/DD Investment purchased on a when-issued or delayed delivery basis. N/R Investment is not rated. 144A Securities are exempt from registration under Rule 144A of the Securities Act of 1933, as amended. These securities 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 lien 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 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. (4) Ratings: Using the higher of Standard & Poor's or Moody's rating. Ratings below Baa by Moody's Investor Service, Inc. or BBB by Standard & Poor's Group are considered to be below investment grade. (5) Position represents an unfunded loan commitment outstanding at January 31, 2006. (6) At or subsequent to January 31, 2006, this issue was under the protection of the Federal Bankruptcy Court. WI/DD Investment purchased on a when-issued or delayed delivery basis. N/R Investment is not rated. 144A Securities are exempt from registration under Rule 144A of the Securities Act of 1933, as amended. These securities 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 lien of cash payment, interest accrued on "Payment in Kind" investment increases principal outstanding.

See accompanying notes to financial statements. 34 Notes to FINANCIAL STATEMENTS (Unaudited) 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. Prior to the commencement of operations of Floating Rate Income (JFR) and Floating Rate Income Opportunity (JRO), each Fund had no operations other than those related to organizational matters, the initial capital contribution of $100,275 per Fund by Nuveen Institutional Advisory Corp. ("NIAC") the Funds' previous adviser and a wholly owned subsidiary of Nuveen Investments, Inc. ("Nuveen"). The recording of the organization expenses ($11,500 per Fund) and their reimbursement by Nuveen Investments, LLC, also a wholly owned subsidiary of Nuveen. 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, 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 and delayed delivery purchase commitments. At January 31, 2006, Senior Income (NSL), Floating Rate Income (JFR) and Floating Rate Income Opportunity (JRO) had outstanding when-issued and delayed delivery purchase commitments of $17,672,725, $23,961,456 and $8,961,456, respectively. Investment Income 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 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 (Unaudited) (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 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. 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. 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. Effective September 24, 2004, 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" in the Statement of Operations. 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. Floating Rate Income Opportunity (JRO) did not invest in a SAMI during the six months ended January 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 has agreed to reimburse all organization expenses (approximately $11,500 per Fund) and pay all Common share offering costs (other than the sales load) that exceed $.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 $812,340, 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 $5,105,746, respectively) were recorded as a reduction to paid-in surplus. Indemnifications Under the Funds' organizational documents, its 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. At January 31, 2006, the cost of investments was as follows: FLOATING FLOATING RATE SENIOR RATE INCOME INCOME INCOME OPPORTUNITY (NSL) (JFR) (JRO) --------------------------------------------------------------------------------------------------------------- Cost of investments $413,541,638 $1,074,775,496 $640,502,061 =============================================================================================================== Gross unrealized appreciation and gross unrealized depreciation of investments at January 31, 2006, were as follows: FLOATING FLOATING RATE SENIOR RATE INCOME INCOME INCOME OPPORTUNITY (NSL) (JFR) (JRO) --------------------------------------------------------------------------------------------------------------- Gross unrealized: Appreciation $ 4,687,014 $7,732,543 $ 4,987,567 Depreciation (13,041,863) (7,055,828) (3,991,507) --------------------------------------------------------------------------------------------------------------- Net unrealized appreciation (depreciation) of investments $ (8,354,849) $ 676,715 $ 996,060 =============================================================================================================== The tax components of undistributed net ordinary income and net realized gains at July 31, 2005, the Funds' last fiscal year end, were as follows: FLOATING FLOATING RATE SENIOR RATE INCOME INCOME INCOME OPPORTUNITY (NSL) (JFR) (JRO) --------------------------------------------------------------------------------------------------------------- Undistributed net ordinary income * $ 3,141,702 $ 3,566,259 $ 782,340 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 1, 2005, paid on August 1, 2005. The tax character of distributions paid during the fiscal year ended July 31, 2005, the Funds' last fiscal year end, was designated for purposes of the dividends paid deduction as follows: FLOATING FLOATING RATE SENIOR RATE INCOME INCOME INCOME OPPORTUNITY (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. 38 At July 31, 2005, the Funds' last fiscal year end, 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 $14,916,928 $ -- $ -- 2011 10,704,254 -- -- 2012 -- -- -- 2013 -- 819,145 30,377 -------------------------------------------------------------------------------- Total $25,621,182 $ 819,145 $ 30,377 ================================================================================ The following Funds elected to defer net realized losses from investments incurred from November 1, 2004 through July 31, 2005 ("post-October losses") in accordance with Federal income tax regulations. The following post-October losses were treated as having arisen on the first day of the current fiscal year. FLOATING FLOATING RATE RATE INCOME INCOME OPPORTUNITY (JFR) (JRO) -------------------------------------------------------------------------------- $2,068,644 $1,679,895 ================================================================================ 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 the Adviser, 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 (Unaudited) (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 January 31, 2006, the complex-level fee was .1891%. 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 commitments. 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 January 31, 2006, Senior Income (NSL), Floating Rate Income (JFR) and Floating Rate Income Opportunity (JRO) had unfunded senior loan commitments of $1,500,000, $3,450,306 and $4,048,418, 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 January 31, 2006: COMMITMENT COUNTERPARTY AMOUNT VALUE -------------------------------------------------------------------------------- Bear, Stearns & Co., Inc. $2,000,000 $1,936,000 Morgan Stanley 1,640,000 1,587,520 ================================================================================ Floating Rate Income (JFR) and Floating Rate Income Opportunity (JRO) had no such participation commitments outstanding at January 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 make advances to Senior Income (NSL) and to many other borrowers who comprise Falcon's total borrowing base. For the six months ended January 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 4.01%. 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 six months ended January 31, 2006. 41 Notes to FINANCIAL STATEMENTS (Unaudited) (continued) 9.

A PHONE CALL IS ALL IT TAKES TO SET UP YOUR REINVESTMENT ACCOUNT. 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 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.

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 (ALSO KNOWN AS DIVIDEND YIELD OR CURRENT YIELD): An investment's current annualized dividend divided by its current market price. 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.
