Chairman's
     LETTER TO SHAREHOLDERS

I am pleased to report that for the period ended January 31, 2005, your Fund
continued to provide you with attractive monthly income from a portfolio
primarily composed of senior corporate loans.

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


"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 Fund may help you achieve and benefit from greater portfolio
diversification. Your financial advisor can explain these advantages in more
detail. I urge you to contact him or her soon for more information on this
important investment strategy.

I also urge you to consider receiving future Fund reports and other Fund
information faster by using e-mails and the Internet. Sign up is quick and easy
- see the inside front cover of this report for instructions.

For more than 100 years, Nuveen has specialized in offering quality investments
such as your Fund to those seeking to accumulate and preserve wealth. Our
mission continues to be to assist you and your financial advisor by offering the
investment solutions and services that can help you secure your long-term
financial goals. We thank you for choosing us as a partner as you work toward
that objective.

Again, thank you for the confidence you have shown in Nuveen Investments.

Sincerely,

/s/Timothy R. Schwertfeger

Nuveen Closed-End Exchange-Traded 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 period ended January 31, 2005.

WHAT MANAGEMENT STRATEGIES AND TACTICS DID YOU EMPLOY IN THESE FUNDS OVER THE
SIX-MONTH PERIOD COVERED BY THIS REPORT?

For NSL, we continued to employ a value-oriented investment management strategy
during the six months ended January 31, 2005. We sought to purchase what we
judged to be high-quality loans with strong asset protection and attractive
coupons, using a disciplined, fundamental approach to evaluate the cash flow and
asset quality of potential investments. We focused on purchasing loans that
would enhance the diversity of NSL's portfolio while seeking to maintain its
current income stream.

We also selectively added discounted loans with what we believed to be
attractive upside potential. We continued to seek stressed loans with what we
considered to be strong asset coverage, attractive relative value
characteristics and sound business fundamentals. In certain cases, we reduced
the Fund's exposure to companies that seemed to have inadequate asset
protection, negative earnings volatility, insufficient liquidity or lower
coupons. We opportunistically liquidated equity investments and sold out of
loans that we thought had the potential for credit deterioration or that did not
fit our other investment parameters.

For JFR, we focused during this period on meeting our internal yield and credit
quality targets by purchasing what we judged to be higher quality loans with
strong asset protection and attractive coupons. Specifically, we sought to
purchase loans with appealing relative value characteristics, upgrade the
portfolio as the credit cycle improved, and selectively add discount loans as
attractive opportunities arose. This helped us maintain the income stream of the
Fund and enhance the diversity of JFR's portfolio. At the same time, we tried to
reduce our exposure to loans with higher-than-warranted valuations, mounting
credit concerns or deteriorating fundamentals.

We also purchased discounted loans for JFR that had what we believed to be
attractive upside potential. We continued to seek stressed loans that exhibited
strong asset coverage, attractive relative value characteristics, and sound
business fundamentals. for NSL, we sought to reduce exposure to companies with
inadequate asset protection, negative earnings volatility, insufficient
liquidity or lower coupons, and we opportunistically liquidated holdings that we
thought had the potential for credit deterioration or that did not fit our other
investment parameters.

In JRO, the newest Fund, we focused on meeting internal yield and credit quality
targets by purchasing what we considered to be higher quality loans with strong
asset protection and attractive coupons. During the first half of the six-month
reporting period, we completed the invest-up stage of the Fund's portfolio. In
the latter half of the reporting period, we concentrated on purchasing loans
with attractive relative value characteristics. We sought to maintain a high
current income stream and to enhance the diversity of JRO's portfolio, while at
the same time reducing our exposure to loans with substantially elevated prices,
mounting credit concerns or deteriorating industry fundamentals.

As for JFR, we also selectively added discounted loans with what we believed to
have attractive upside potential. We continued to seek distressed loans with
strong asset coverage and sound business fundamentals. We sold out of loans with
greater perceived potential for credit deterioration or that no longer fit our
other investment parameters.

*    Six month returns are cumulative; returns for one year and five years are

Past performance does not guarantee future results. 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, NSL and JFR outperformed the unmanaged,
unleveraged CSFB Leveraged Loan Index. JRO, on which we spent a good portion of
the period investing the assets raised through its common and preferred share
offerings, underperformed the CSFB index during this period.

One of the primary factors benefiting the performance of NSL and JFR 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 strategy can also provide opportunities for additional income
and total returns for common shareholders when short-term interest rates remain
low relative to the amount the Funds are earning from the adjustable rate loans
in their portfolios.

Other factors that benefited the performance of NSL over this period included
the meaningful price appreciation of several stressed credits. Norwood, Western
Industries, and Mirant registered the strongest returns during the period ended
January 31, 2005. Conversely, MetalForming Technologies negatively impacted the
Fund's overall performance during this period.

In JFR, Aladdin Gaming, Century Cable, and Conseco were the strongest performing
loans during the period ending January 31, 2005. There were no holdings that had
a material negative impact on the portfolio during the period.

As noted, JRO was completing its initial investment process during this
reporting period. As a result, the Fund did not benefit from a full six-months
of the returns of some of its better performing holdings, including Cablevision,
Graham Packaging, and Knoll. There were no holdings in this Fund that had a
material negative impact on the portfolio.


1    The CSFB Leveraged Loan Index is an unmanaged, unleveraged index consisting
     of approximately $150 billion of tradable term loans with at least one year
     to maturity and rated BBB or lower.

                                       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 and share price, it generally works to enhance the amount
of income the Fund has to distribute to its common shareholders as long as the
dividends the Fund pays to its preferred shareholders are less than the interest
rates the Fund is receiving from its portfolio of loans.

Since each of these Funds invests in adjustable rate loans, their income streams
can be expected to rise or fall over time to reflect the movement of
shorter-term interest rates. These rates generally were rising over the course
of this six-month reporting period, and this led to two monthly dividend
increases in NSL and one increase in the dividend of JFR. JRO made its initial
monthly dividend declaration during this reporting period, and as of January 31,
2005, had maintained a stable dividend.

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) as 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, 2005, NSL had a positive UNII
balance for both financial statement and tax purposes and JFR and JRO had
negative UNII balances for financial statement purposes and positive UNII
balances for tax purposes.

As of January 31, 2005, the Funds were trading at premiums to their net asset
values as shown in the accompanying chart.

                    (1)  All percentages shown in the Portfolio of Investments
                         are based on net assets applicable to Common shares
                         unless otherwise noted.

                    (2)  Senior Loans in which the Fund invests generally pay
                         interest at rates which are periodically adjusted by
                         reference to a base short-term, floating lending rate
                         plus 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.

                    *    Senior Loans in the Fund's portfolio generally are
                         subject to mandatory and/or optional prepayment.
                         Because of these mandatory prepayment conditions and
                         because there may be significant economic incentives
                         for a Borrower to prepay, prepayments of Senior Loans
                         in the Fund's portfolio may occur. As a result, the
                         actual remaining maturity of Senior Loans held in the
                         Fund's portfolio may be substantially less than the
                         stated maturities shown. The Fund estimates that the
                         actual average maturity of the Senior Loans held in its
                         portfolio will be approximately 18-24 months.

                    **   Ratings below Baa by Moody's Investor Service, Inc. or
                         BBB by Standard & Poor's Group are considered to be
                         below investment grade.

                    (a)  At or subsequent to January 31, 2005, this issue was
                         non-income producing.

                    (b)  At or subsequent to January 31, 2005, this issue was
                         under the protection of the federal bankruptcy court.

                    (c)  On January 1, 2002, CFR Holdings, Inc. (an entity
                         formed by Nuveen for the benefit of the Nuveen Funds
                         owning various interests in CanFibre of Riverside) took
                         possession of the CanFibre of Riverside assets on
                         behalf of the various Nuveen Funds. CFR Holdings, Inc.
                         determined that a sale of the facility was in the best
                         interest of shareholders and proceeded accordingly.

                    (d)  Purchased on a when-issued or delayed delivery basis.

                    (e)  Portion purchased on a when-issued or delayed delivery
                         basis.

                    (f)  Position represents an unfunded loan commitment
                         outstanding at January 31, 2005.

                    (g)  Portion of position represents an unfunded loan
                         commitment outstanding at Januray 31, 2005.

                    (h)  Investment valued at fair value using methods
                         determined in good faith by or at the direction of the
                         Board of Trustees.

                         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, the borrower or counterparty
                         will provide the Fund with the weighted average coupon
                         rate and, if still unknown, the maturity date.

                   (PIK) In lieu of cash payment, interest accrued on "Payment
                         in Kind" investment increases principal outstanding.

                    (1)  All percentages shown in the Portfolio of Investments
                         are based on net assets applicable to Common shares
                         unless otherwise noted.

                    (2)  Senior Loans in which the Fund invests generally pay
                         interest at rates which are periodically adjusted by
                         reference to a base short-term, floating lending rate
                         plus 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.

                    *    Senior Loans in the Fund's portfolio generally are
                         subject to mandatory and/or optional prepayment.
                         Because of these mandatory prepayment conditions and
                         because there may be significant economic incentives
                         for a Borrower to prepay, prepayments of Senior Loans
                         in the Fund's portfolio may occur. As a result, the
                         actual remaining maturity of Senior Loans held in the
                         Fund's portfolio may be substantially less than the
                         stated maturities shown. The Fund estimates that the
                         actual average maturity of the Senior Loans held in its
                         portfolio will be approximately 18-24 months.

                    **   Ratings below Baa by Moody's Investor Service, Inc. or
                         BBB by Standard & Poor's Group are considered to be
                         below investment grade.

                    (a)  At or subsequent to January 31, 2005, this issue was
                         under the protection of the federal bankruptcy court.

                    (b)  Purchased on a when-issued or delayed delivery basis.

                    (c)  Position represents an unfunded loan commitment
                         outstanding at January 31, 2005.

                    (d)  Portion of position represents an unfunded loan
                         commitment outstanding at Januray 31, 2005.

                    (e)  Investment valued at fair value using methods
                         determined in good faith by or at the direction of the
                         Board of Trustees.

                    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, the borrower or counterparty
                         will provide the Fund with the weighted average coupon
                         rate and, if still unknown, the maturity date.

                   (PIK) In lieu of cash payment, interest accrued on "Payment
                         in Kind" investment increases principal outstanding.

                    N/R  Investment is not rated.

                ==================================================================================================================


                    (1)  All percentages shown in the Portfolio of Investments
                         are based on net assets applicable to Common shares
                         unless otherwise noted.

                    (2)  Senior Loans in which the Fund invests generally pay
                         interest at rates which are periodically adjusted by
                         reference to a base short-term, floating lending rate
                         plus 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.

                    *    Senior Loans in the Fund's portfolio generally are
                         subject to mandatory and/or optional prepayment.
                         Because of these mandatory prepayment conditions and
                         because there may be significant economic incentives
                         for a Borrower to prepay, prepayments of Senior Loans
                         in the Fund's portfolio may occur. As a result, the
                         actual remaining maturity of Senior Loans held in the
                         Fund's portfolio may be substantially less than the
                         stated maturities shown. The Fund estimates that the
                         actual average maturity of the Senior Loans held in its
                         portfolio will be approximately 18-24 months.

                    **   Ratings below Baa by Moody's Investor Service, Inc. or
                         BBB by Standard & Poor's Group are considered to be
                         below investment grade.

                    (a)  At or subsequent to January 31, 2005, this issue was
                         under the protection of the federal bankruptcy court.

                    (b)  Purchased on a when-issued or delayed delivery basis.

                    (c)  Portion purchased on a when-issued or delayed delivery
                         basis.

                    (d)  Position represents an unfunded loan commitment
                         outstanding at January 31, 2005.

                    (e)  Portion of position represents an unfunded loan
                         commitment outstanding at Januray 31, 2005.

                    (f)  Investment valued at fair value using methods
                         determined in good faith by or at the direction of the
                         Board of Trustees.

                    144A 144A securities are those which 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, the borrower or counterparty
                         will provide the Fund with the weighted average coupon
                         rate and, if still unknown, the maturity date.

                    N/R  Investment is not rated.

       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.

Effective January 1, 2005, Nuveen Institutional Advisory Corp. ("NIAC") the
Funds' previous adviser, and its affiliate, Nuveen Advisory Corp. ("NAC"), were
merged into Nuveen Asset Management ("NAM"), each wholly owned subsidiaries of
Nuveen Investments, Inc. ("Nuveen"). As a result of the merger, NAM is now the
Adviser to all funds previously advised by either NIAC or NAC.

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 NIAC, 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 most 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 the Adviser, 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. High-grade 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, 2005, Senior Income (NSL), Floating Rate
Income (JFR) and Floating Rate Income Opportunity (JRO) had outstanding
when-issued and delayed delivery purchase commitments of $25,003,750 $48,606,250
and $57,993,750.

Notes to
    FINANCIAL STATEMENTS (Unaudited) (continued)



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.

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

The Funds intend to declare monthly income distributions to Common shareholders.
Net realized capital gains from investment transactions, if any, are distributed
to shareholders not less frequently than annually. Furthermore, capital gains
are distributed only to the extent they exceed available capital loss
carryforwards.

Distributions to Common shareholders 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 on the Taxable Auctioned
Preferred shares 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 below.

Effective May 21, 2004, Floating Rate Income (JFR) issued 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 on each series is
determined every seven days, pursuant to a dutch auction process overseen by the
auction agent, and is payable weekly 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
on each series is determined every seven days, pursuant to a dutch auction
process overseen by the auction agent, and is payable weekly 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, 2005.

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.


                                       34



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 ($1,213,989 and $850,593, 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
($8,425,000 and $5,170,000, 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. FUND SHARES

Transactions in Common and Preferred shares were as follows:

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.

At January 31, 2005, the cost of investments was as follows:

                                                                        FLOATING

5. MANAGEMENT FEES AND OTHER TRANSACTIONS WITH AFFILIATES

As approved by the Board of Trustees, effective August 1, 2004, a complex-wide
management fee structure was adopted for all funds sponsored by the Adviser, or
its predecessor, and its affiliates. The fee structure separates each fund's
management fee into two components - a complex-level component, based on the
aggregate amount of all fund assets managed by the Adviser and its affiliates,
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 and its
affiliates. Under no circumstances will this pricing structure result in a fund
paying management fees at a rate higher than would otherwise have been
applicable had the complex-wide management fee structure not been implemented.
As a consequence of this new management fee structure, the funds' effective
management fees were reduced by approximately .009% as of February 28, 2005.

Effective August 1, 2004, the annual fund-level fee, payable monthly, for each
of the Funds is based upon the average daily Managed Assets of each Fund as
follows:

                                                             SENIOR INCOME (NSL)

================================================================================

Effective August 1, 2004, 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 follows:

COMPLEX-LEVEL ASSETS(1)                                   COMPLEX-LEVEL FEE RATE

For the next $3 billion                                                   .1325
For the next $3 billion                                                   .1250

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.

Under Senior Income's (NSL) and Floating Rate Income Opportunity's (JRO)
investment management agreements with the Adviser, each Fund paid a .8500%
annual management fee rate through July 31, 2004, payable monthly, which were
based upon the average daily Managed Assets of each Fund.

Under Floating Rate Income's (JFR) investment management agreement with the
Adviser, the Fund paid through July 31, 2004, an annual management fee, payable
monthly, at the rates set forth below, which were based upon the average daily
Managed Assets of the Fund as follows:

Notes to
    FINANCIAL STATEMENTS (Unaudited) (continued)



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 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:

6. COMMITMENTS

Pursuant to the terms of certain of the variable rate senior loan agreements,
the Funds may have unfunded senior loan commitments. The Funds will maintain
with its custodian, cash, liquid securities and/or liquid senior loans having an
aggregate value at least equal to the amount of unfunded senior loan
commitments. At January 31, 2005, Senior Income (NSL) had unfunded loan
commitments of $2,800,000, Floating Rate Income (JFR) had $11,963,636 and
Floating Rate Income Opportunity (JRO) had $10,014,514 in unfunded loan
commitments.

7. SENIOR LOAN PARTICIPATION COMMITMENTS

With respect to the senior loans held in the Funds' portfolio, the Funds may: 1)
invest in assignments; 2) act as a participant in primary lending syndicates; or
3) invest in participations. If the Funds purchase a participation of a senior
loan interest, the Funds 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 Funds not only assume the credit risk of the
Borrower, but also that of the Selling Participant or other persons
interpositioned between the Funds and the Borrower.

Senior Income (NSL) had the following participation commitments outstanding at
January 31, 2005:

COUNTERPARTY                     COMMITMENT AMOUNT                  MARKET VALUE
--------------------------------------------------------------------------------
Bear, Stearns & Co., Inc.            $2,000,000                       $1,974,375
Morgan Stanley                        1,640,000                        1,618,998
================================================================================

Floating Rate Income (JFR) and Floating Rate Income Opportunity (JRO) had no
such participation commitments outstanding at January 31, 2005.

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 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,
2005, the average daily balance of borrowings under the commercial paper program
agreement was $103 million with an average interest rate of 1.94%.

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, 2005.

Announcement Regarding Parent Company of Adviser

Recently, The St. Paul Travelers Companies, Inc. announced that it intended to
explore strategic alternatives to divest its equity stake in Nuveen. This
divestiture could take the form of a sale by The St. Paul Travelers Companies,
Inc. of its interest in Nuveen to another party or the form of the sale of its
interest to the public in a registered, broadly disseminated offering. Any
resulting divestiture could be deemed to be an "assignment" (as defined in the
1940 Act) of the investment management agreements between the Funds and NAM and
the investment sub-advisory agreements between NAM and Symphony, which would
result in the automatic termination of each agreement. The Board of Trustees
thereupon may consider both an interim investment management agreements and
interim investment sub-advisory agreements (as permitted under the 1940 Act) and
new ongoing investment management and investment sub-advisory agreements. If
approved by the Board of Trustees, the new ongoing agreements would be presented
to the Funds' shareholders for approval, and would take effect upon such
approval. There can be no assurance that these approvals will be obtained.

Reinvest Automatically
       EASILY AND CONVENIENTLY


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



NUVEEN CLOSED-END EXCHANGE-TRADED FUNDS
DIVIDEND REINVESTMENT PLAN

Your Nuveen Closed-End Exchange-Traded Fund allows you to conveniently reinvest
dividends and/or capital gains distributions in additional fund shares.

By choosing to reinvest, you'll be able to invest money regularly and
automatically, and watch your investment grow through the power of compounding.

It is important to note that an automatic reinvestment plan does not ensure a
profit, nor does it protect you against loss in a declining market.

EASY AND CONVENIENT

To make recordkeeping easy and convenient, each month you'll receive a statement
showing your total dividends and distributions, the date of investment, the
shares acquired and the price per share, and the total number of shares you own.

HOW SHARES ARE PURCHASED

The shares you acquire by reinvesting will either be purchased on the open
market or newly issued by the Fund. If the shares are trading at or above net
asset value at the time of valuation, the Fund will issue new shares at the
greater of the net asset value or 95% of the then-current market price. If the
shares are trading at less than net asset value, shares for your account will be
purchased on the open market. Dividends and distributions received to purchase
shares in the open market will normally be invested shortly after the dividend
payment date. No interest will be paid on dividends and distributions awaiting
reinvestment. Because the market price of 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.

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.

AVERAGE EFFECTIVE MATURITY: The average of all the maturities of the bonds in a
Fund's portfolio, computed by weighting each maturity date (the date the
security comes due) by the market value of the security. This figure does not
account for the likelihood of prepayments or the exercise of call provisions.

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.
