Chairman's
LETTER TO SHAREHOLDERS

(TIMOTHY

Dear Shareholder:

Once again, I am pleased to report that over the six-month period covered by this report your Fund continued to provide you with attractive income. For more details about the management strategy and performance of your Fund, please read the Portfolio Managers' Comments, the Common Share Distribution and Share Price Information, and the Performance Overview sections of this report.

With the recent volatility in the bond and stock market, many have begun to wonder which way the market is headed, and whether they need to adjust their holdings of investments. No one knows what the future will bring, which is why we think a well-balanced portfolio that is structured and carefully monitored with the help of an investment professional is an important component in achieving your long-term financial goals. A well-diversified portfolio may actually help to reduce your overall investment risk, and we believe that investments like your Nuveen Investments Fund can be important building blocks in a portfolio crafted to perform well through a variety of market conditions.

I also wanted to update you on some important news about Nuveen Investments. Since the last shareholder report, a group led by Madison Dearborn Partners, LLC, completed its acquisition of Nuveen Investments. This change in corporate ownership had no impact on the investment objectives, portfolio management strategies or dividend policy of your Fund.

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. 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.

Sincerely,

(TIMOTHY SCHWERFEGER SIG)

Chairman of the Board

Portfolio Managers' COMMENTS

NUVEEN INVESTMENTS CLOSED-END FUNDS NSL, JFR, JRO

The Funds' investment portfolios have been managed by Gunther Stein and Lenny Mason of Symphony Asset Management, LLC, an affiliate of Nuveen Investments, since 2001. 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 performance of the Funds for the six-month period ended January 31, 2008.

WHAT KEY STRATEGIES WERE USED TO MANAGE THE FUNDS?

Throughout this six-month period, we continued to manage each Fund's portfolio using fundamental analysis to select senior loans that we believed offered strong asset coverage and attractive risk-adjusted return potential. We avoided the senior loans of most automotive part suppliers as well as smaller homebuilders and land developers, even though many loans in these sectors traded at discounts throughout the year. We also avoided many loans to smaller companies that were done to finance leveraged buyouts (LBO). We didn't believe that there was sufficient value in many small-company loans to compensate for potential illiquidity and volatility if earnings of the companies issuing them should become challenged.


Discussions of specific investments are for illustrative purposes only and are not intended as recommendations of individual investments. The views expressed in this commentary represent those of the portfolio managers as of the date of this report and are subject to change at any time, based on market conditions and other factors. The Funds disclaim any obligation to advise shareholders of such changes.

We also focused on adding quality new-issue senior loans, which often were priced at a discount to par and were structured with strong covenant protection. We continued to avoid the vast majority of second lien loans. Similar to small-company loans, we didn't believe that second lien loans offered sufficient additional yield to compensate investors for potentially increased volatility and lower recovery rates.

Although the performance of all three portfolios suffered as a result of the broad-based sell-off in loans over this period, we believe that market dislocation provided an opportunity to buy loans in good companies with strong covenants at attractive prices.

HOW DID THE FUNDS PERFORM OVER THIS SIX-MONTH PERIOD?

The performance of the Funds, as well as the performance of a widely followed market index are presented in the accompanying table.

Total Returns on Net Asset Value*
For periods ended 1/31/08

 SIX-MONTH 1-YEAR 5-YEAR
 --------- ------ -------
NSL -3.81% -5.91% 7.87%
JFR -3.54% -6.44% NA
JRO -4.03% -6.68% NA
CSFB Leveraged Loan Index(1) -1.45% -2.11% 5.31%


*Six-month returns are cumulative; returns for one-year and five-year are annualized.

Past performance does not guarantee future results. Current performance may be higher or lower than the data shown. Returns do not reflect the deduction of taxes that shareholders may have to pay on Fund distributions or upon the sale of Fund shares.

For additional information, see the individual Performance Overview for your Fund in this report.


1 The CSFB Leveraged Loan Index is a representative, unmanaged index of tradeable, senior, U.S. dollar-denominated leveraged loans. It is not possible to invest directly in an Index.

For the six-months ended January 31, 2008, the cumulative return on net asset value for each Fund underperformed the CSFB Leveraged Loan Index.

The benchmark returns shows that the six-month period presented a very challenging and unforgiving market environment. The Funds' underperformance was due in part to its use of financial leverage because the cost of leverage exceeded the returns generated by the Funds' investment portfolios. Additionally, leverage tended to exacerbate the price declines suffered by the Funds' holdings. However, leverage is a strategy that had contributed to enhanced dividends and returns in the past, and we believe it retains the potential to continue to so in the future.

All three Funds experienced downside pressure across their loan portfolios as a result of the broad sell-off in loans. Given the liquidity-driven market conditions during the second half of 2007, many of the large broadly-syndicated LBO loans positions we had were under particularly heavy price pressure. There were no individual company-specific events that negatively impacted performance of any of the Funds. Rather, their performance was reflective of the loan market in general, which was influenced heavily by supply and demand factors. Default rates remained relatively low and fundamental factors remained relatively strong throughout 2007 compared to historical levels.

RECENT DEVELOPMENTS IN THE AUCTION RATE PREFERRED MARKETS

Beginning in February 2008, after the close of this reporting period, more shares for sale were submitted in the regularly scheduled auctions for the Preferred shares issued by the Funds than there were offers to buy. This meant that these auctions "failed to clear," and that many Preferred shareholders who wanted to sell their shares in these auctions were unable to do so. This decline in liquidity in auction preferred shares did not lower the credit quality of these shares, and Preferred shareholders unable to sell their shares received distributions at the "maximum rate" calculated in accordance with the pre-established terms of the Preferred shares. At the time this report was prepared, the Funds' managers could not predict when future auctions might succeed in attracting sufficient buyers for the shares offered. The Funds' managers are working diligently to develop mechanisms designed to improve the liquidity of the Preferred shares, or refund them, but at present there is no assurance that these efforts will succeed.

5

These developments do not affect the management or investment policies of the Funds. However, one implication of these auction failures for common shareholders is that the Funds' cost of leverage will be higher than it otherwise would have been had the auctions continued to be successful. As a result, the Funds' future common share earnings may be lower than they otherwise would have been.

For current, up-to-date information please visit the Nuveen CEF Auction Rate Preferred Resource Center,

Common Share
Distribution and Share Price
INFORMATION

As noted earlier, these Funds use financial leverage to potentially enhance opportunities for additional income for common shareholders. The Funds' use of this leverage strategy continued to provide incremental income, although the extent of this benefit was reduced to some degree by short-term interest rates that remained relatively high during the earlier part of the period. This, in turn, kept the Funds' borrowing costs high. This is one reason all three Funds declared one monthly distribution decrease over the six-month period.

During certain periods, the Funds 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) as part of the Fund's common share 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 common share NAV. As of January 31, 2008, all three Funds had positive UNII balances, based upon our best estimate, for tax purposes. NSL and JFR had positive UNII balances and JRO had a negative UNII balance for financial statement purposes.

As of January 31, 2008, the Funds were trading at discounts to their common share NAVs as shown in the table below.

NSL
Nuveen Senior Income Fund (continued)

Portfolio of INVESTMENTS January 31, 2008 (Unaudited)

 (1) All percentages shown in the Portfolio of Investments are based on net assets applicable
 to Common shares unless otherwise noted.
 (2) 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.
 (3) Ratings: Using the higher of Standard & Poor's Group ("Standard & Poor's") or Moody's
 Investor Service, Inc. ("Moody's") rating. Ratings below BBB by Standard & Poor's or Baa
 by Moody's are considered to be below investment grade.
 (4) Senior Loans 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.
 (5) At or subsequent to January 31, 2008, this issue was under the protection of the Federal
 Bankruptcy Court.
 (6) Non-income producing. Non-income producing, in the case of a Senior Loan, generally
 denotes that the issuer has defaulted on the payment of principal or interest or has filed
 for bankruptcy.
 (7) Position or portion of position represents an unfunded Senior Loan commitment outstanding
 at January 31, 2008.
 (8) Negative value represents unrealized depreciation on unfunded Senior Loan commitment
 outstanding at January 31, 2008.
 (9) Investment valued of fair value using methods determined in good faith by, or at the
 discretion of, the Board of Trustees.
 (10) Borrowings and Preferred Shares, at Liquidation Value as a percentage of total investments
 are (27.2)% and (12.2)%, respectively.
 N/R Not rated.
 DD1 Portion of investment purchased on a delayed delivery basis.
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.
 PIK In lieu of cash payment, interest accrued on "Payment in Kind" investment increases
 principal outstanding.
 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.

See accompanying notes to financial statements.

 (1) All percentages shown in the Portfolio of Investments are based on net assets applicable
 to Common shares unless otherwise noted.
 (2) 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.
 (3) Ratings: Using the higher of Standard & Poor's Group ("Standard & Poor's") or Moody's
 Investor Service, Inc. ("Moody's") rating. Ratings below BBB by Standard & Poor's or Baa
 by Moody's are considered to be below investment grade.
 (4) Senior Loans 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.
 (5) Position or portion of position represents an unfunded Senior Loan commitment outstanding
 at January 31, 2008.
 (6) Negative value represents unrealized depreciation on unfunded Senior Loan commitment
 outstanding at January 31, 2008.
 (7) Preferred Shares, at Liquidation Value as a percentage of total investments is (41.0)%.
 N/R Not rated.
 DD1 Portion of investment purchased on a delayed delivery basis.
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.

 (1) All percentages shown in the Portfolio of Investments are based on net assets applicable
 to Common shares unless otherwise noted.
 (2) 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.
 (3) Ratings: Using the higher of Standard & Poor's Group ("Standard & Poor's") or Moody's
 Investor Service, Inc. ("Moody's") rating. Ratings below BBB by Standard & Poor's or Baa
 by Moody's are considered to be below investment grade.
 (4) Senior Loans 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.
 (5) Position or portion of position represents an unfunded Senior Loan commitment outstanding
 at January 31, 2008.
 (6) Negative value represents unrealized depreciation on unfunded Senior Loan commitment
 outstanding at January 31, 2008.
 (7) Preferred Shares, at Liquidation Value as a percentage of total investments is (41.2)%.
 N/R Not rated.
 DD1 Portion of investment purchased on a delayed delivery basis.
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.

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.

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 Investments, Inc. ("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/delayed delivery basis may have extended settlement periods. Any investments so purchased are subject to market fluctuation during this period. The Funds have instructed the custodian to segregate assets with a current value at least equal to the amount of the when-issued/delayed delivery purchase commitments. At January 31, 2008, Senior Income (NSL), Floating Rate Income (JFR) and Floating Rate Income Opportunity (JRO) had outstanding when-issued/delayed delivery purchase commitments of $10,415,000, $8,646,250 and $2,610,000, 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, if any, 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.

36

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.

Effective January 31, 2008, the Funds adopted Financial Accounting Standards Board (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 affirmative evaluation of tax positions taken or expected to be taken in the course of preparing the Funds' tax returns to determine whether it is "more-likely-than-not" (i.e. greater than 50-percent) of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold may result in a tax benefit or expense in the current year.

Implementation of FIN 48 required management of the Funds to analyze all open tax years, as defined by the statute of limitations, for all major jurisdictions, which includes federal and certain states. Open tax years are those that are open for examination by taxing authorities (i.e. the last four tax year ends and the interim tax period since then). The Funds have no examinations in progress.

For all open tax years and all major taxing jurisdictions through the end of the reporting period, management of the Funds has reviewed all tax positions taken or expected to be taken in the preparation of the Funds' tax returns and concluded the adoption of FIN 48 resulted in no impact to the Funds' net assets or results of operations as of and during the six months ended January 31, 2008.

The Funds are also not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months.

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 -- Borrowings.

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.

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 net credits earned on each Fund's cash on deposit with the bank. Such deposit arrangements are an alternative to overnight investments. Credits for cash balances may be offset by charges for any days on which a Fund overdraws its account at the custodian bank.

Notes to
FINANCIAL STATEMENTS (Unaudited) (continued)

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 account 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.

---------------------------------------------------------------------------------------------------------------------------

4. INCOME TAX INFORMATION

The following information is presented on an income tax basis. Differences between amounts for financial statement and federal income tax purposes are primarily due to the treatment of paydown gains and losses, 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 presented in the annual report, based on their federal tax basis treatment; temporary differences do not require reclassification. Temporary and permanent differences do not impact the net asset values of the Funds.

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)

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
------------------------------------------------------------------------------------------------------------------------

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, 2008, the complex-level fee was .1847%.

Effective August 20, 2007, the complex-level fee schedule is as follows:

COMPLEX-LEVEL ASSET BREAKPOINT LEVEL (1) EFFECTIVE RATE AT BREAKPOINT LEVEL
------------------------------------------------------------------------------------------------
$55 billion .2000%
$56 billion .1996
$57 billion .1989

$125 billion .1599
$200 billion .1505
$250 billion .1469
$300 billion .1445
------------------------------------------------------------------------------------------------

Prior to August 20, 2007, the complex-level fee schedule was as follows:

COMPLEX-LEVEL ASSET BREAKPOINT LEVEL (1) EFFECTIVE RATE AT BREAKPOINT LEVEL
------------------------------------------------------------------------------------------------
$55 billion .2000%
$56 billion .1996
$57 billion .1989

$91 billion .1698
$125 billion .1617
$200 billion .1536
$250 billion .1509
$300 billion .1490
------------------------------------------------------------------------------------------------

(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 preferred stock issued by or borrowings by the Nuveen funds) of Nuveen-sponsored funds in the U.S.

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 portfolios of the Funds. Symphony is compensated for its services to the Funds from the management fees paid to the Adviser.

The Funds pay no compensation directly to those of its Trustees who are affiliated with the Adviser or to its 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:

Agreement and Plan of Merger

On June 20, 2007, Nuveen Investments announced that it had entered into a definitive Agreement and Plan of Merger ("Merger Agreement") with Windy City Investments, Inc. ("Windy City"), a corporation formed by investors led by Madison Dearborn Partners, LLC ("Madison Dearborn"), pursuant to which Windy City would acquire Nuveen Investments. Madison Dearborn is a private equity investment firm based in Chicago, Illinois. The merger was consummated on November 13, 2007.

The consummation of the merger was deemed to be an "assignment" (as that term is defined in the Investment Company Act of 1940) of the investment management agreement between each Fund and the Adviser and, if applicable, the sub-advisory agreement between the Adviser and the sub-adviser of the Funds, and resulted in the automatic termination of each such agreement. The Board of Trustees of each Fund considered and approved a new investment management agreement with the Adviser, and, if applicable, a new sub-advisory agreement between the Adviser and the sub-adviser on the same terms as the previous agreements. Each new ongoing investment management agreement and sub-advisory agreement, if applicable, was approved by the shareholders of each Fund and took effect on November 13, 2007.

The investors led by Madison Dearborn includes an affiliate of Merrill Lynch. As a result, Merrill Lynch is an indirect "affiliated person" (as that term is defined in the Investment Company Act of 1940) of each Fund. Certain conflicts of interest may arise as a result of such indirect affiliation. For example, the Funds are generally prohibited from entering into principal transactions with Merrill Lynch and its affiliates. The Adviser does not believe that any such prohibitions or limitations as a result of Merrill Lynch's affiliation will significantly impact the ability of the Funds to pursue their investment objectives and policies.

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 January 31, 2008, Senior Income (NSL), Floating Rate Income (JFR) and Floating Rate Income Opportunity (JRO) had unfunded senior loan commitments of $2,721,275, $8,524,588 and $5,111,172, 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. At January 31, 2008, there were no such outstanding participation commitments in any of the Funds.

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.

42

Senior Income (NSL) has entered into a commercial paper program ($110 million maximum) with Bank One's (currently JPMorgan) conduit financing agency, Falcon Asset Securitization Corp. ("Falcon"), whose sole purpose is the issuance of high grade commercial paper, uses the proceeds to makes advances to Senior Income (NSL) and to many other borrowers who comprise Falcon's total borrowing base. For the six months ended January 31, 2008, the average daily balance of borrowings under the commercial paper program agreement was $103 million. The interest expense and program usage fees incurred on borrowings is recognized as "Interest expense on borrowings" in the Statement of Operations. The average annualized interest rate for funding and program usage fees on such borrowings for the six months ended January 31, 2007, was 5.75%.

Senior Income (NSL) has also entered into a $110 million liquidity facility. If the facility is utilized, interest on the borrowings would be charged to 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, 2008.

9. NEW ACCOUNTING PRONOUNCEMENT

Financial Accounting Standards Board Statement of Financial Accounting Standards No. 157

In September 2006, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards (SFAS) No. 157, "Fair Value Measurements." This standard establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and requires additional disclosures about fair value measurements. SFAS No. 157 applies to fair value measurements already required or permitted by existing standards. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. The changes to current generally accepted accounting principles from the application of this standard relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. As of January 31, 2008, management does not believe the adoption of SFAS No. 157 will impact the financial statement amounts; however, additional disclosures may be required about the inputs used to develop the measurements and the effect of certain of the measurements included within the Statement of Operations for the period.

10. SUBSEQUENT EVENTS

Auction Rate Preferred Markets

During February 2008, regularly scheduled auctions for the Preferred shares issued by the Funds began attracting more shares for sale than offers to buy. This meant that these auctions "failed to clear," and that many Preferred shareholders who wanted to sell their shares in these auctions were unable to do so. Preferred shareholders unable to sell their shares received distributions at the "maximum rate" calculated in accordance with the pre-established terms of the Preferred stock.

These developments generally do not affect the management or investment policies of the Funds. However, one implication of these auction failures for Common shareholders is that the Funds' cost of leverage will be higher than it otherwise would have been had the auctions continued to be successful. As a result, the Funds' future Common share earnings may be lower than they otherwise would have been.

Distributions to Common Shareholders

The Funds declared Common share dividend distributions from their net investment income which was paid on March 3, 2008, to shareholders of record on February 15, 2008, as follows:

* Annualized. ** Total Return on Market Value is the combination of changes in the market price per share and the effect of reinvested dividend income and reinvested capital gains distributions, if any, at the average price paid per share at the time of reinvestment. The last dividend declared in the period, which is typically paid on the first business day of the following month, is assumed to be reinvested at the ending market price. The actual reinvestment for the last dividend declared in the period may take place over several days, and in some instances may not be based on the market price, so the actual reinvestment price may be different from the price used in the calculation. Total returns are not annualized.

Total Return on Common Share Net Asset Value is the combination of changes in Common share net asset value, reinvested dividend income at net asset value and reinvested capital gains distributions at net asset value, if any. The last dividend declared in the period, which is typically paid on the first business day of the following month, is assumed to be reinvested at the ending net asset value. The actual reinvest price for the last dividend declared in the period may often be based on the Fund's market price (and not its net asset value), and therefore may be different from the price used in the calculation. Total returns are not annualized. *** After custodian fee credit, expense reimbursement from the Adviser and legal fee refund, where applicable.
+ The amounts shown are based on Common share equivalents.
++ - Ratios do not reflect the effect of dividend payments to Preferred shareholders.
- Income ratios reflect income earned on assets attributable to Preferred shares and borrowings, where applicable.

Reinvest Automatically
EASILY and CONVENIENTLY

NUVEEN MAKES REINVESTING EASY. A PHONE CALL IS ALL IT TAKES TO SET UP YOUR REINVESTMENT ACCOUNT.

NUVEEN CLOSED-END FUNDS DIVIDEND REINVESTMENT PLAN

Your Nuveen 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 tax-free compounding. Just like dividends or distributions in cash, there may be times when income or capital gains taxes may be payable on dividends or distributions that are reinvested.

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. 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 on the last business day immediately prior to the purchase date. 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): 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 Fund's 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 Preferred 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.
