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 July 31, 2005.


WHAT WERE THE GENERAL ECONOMIC AND MARKET CONDITIONS YOU FACED DURING THIS
ANNUAL REPORTING PERIOD ENDED JULY 31, 2005?

Over the last twelve months the loan market continued its strong performance.
Low corporate default rates, a slowly improving economy and a benign interest
rate environment all led to strength in the loan market. Leveraged loans
registered positive returns each month, bringing the number of consecutive
monthly gains to 32. The credit markets did experience volatility in April and
May 2005, which was caused by weakness in the automotive sector and the
downgrades of General Motors and Ford. As fears abated in June, both the high
yield and leveraged loan markets improved from the May lows. Rising short-term
interest rates and low default rates continue to drive inflows into the
leveraged loan asset class, as the Federal Reserve boosted the benchmark
interest rate by 200 basis points (bps) over the last year. Macroeconomic trends
remained positive as analysts expect Gross Domestic Product (GDP) real growth to
be in the 3.5% range in 2005 and job creation to continue growing steadily.
Volatile oil prices and commodity costs continue to raise concerns regarding
earnings growth in the coming quarters.

Increased institutional issuance significantly buoyed secondary trading and
demand during the last year. By the end of July 2005, the average price for all
par term loans rose to 100.94 - in other words, a slight premium to par
(100.00). Loans that trade above par made up 80% of trading volume, while loans
above 102 made up 6% of the trading volume at July 31. Senior corporate loans
are typically quoted at interest rate spreads, in basis points (bps), over the
London Interbank Offered Rate (LIBOR), a high quality short-term interest rate
benchmark. B rated loan rate spreads over LIBOR tightened 41 bps from the year
ago period, and higher quality BB rated credit spreads tightened 32 bps. B and
BB rated spreads ended the period at 252 bps and 194 bps, respectively. These
levels, which are somewhat low by historical standards, underscore strong demand
for the leveraged loan asset class over this reporting period.

WHAT WAS YOUR MANAGEMENT STRATEGY DURING THIS PERIOD? DID IT VARY
BY FUND?

We focused on executing a conservative portfolio management strategy which
emphasized carefully selecting both industry sectors and individual companies.
This was our approach for all Funds, whether we were evaluating more traditional
senior corporate loans, or credits from middle market companies for the JRO
portfolio. We analyzed opportunities to upgrade each portfolio by selling loans
in sectors that we believed would have problems over the coming months, and by
rotating into less cyclical sectors that we felt would provide stronger asset
protection. This strategy led us to sell most of our automotive exposure
(excluding aftermarket auto suppliers) before the sector experienced significant
volatility in May. This volatility was due to fears surrounding General Motors
and Ford. Given the robust volume of new deals, we were able to rotate into
loans that we felt provided more asset protection and less earnings volatility.
When evaluating loans, we continued to look at the fundamentals of the issuer.
At the same time, we also closely monitored the relative value of the loans we
held or were considering as compared with other closely related loans or
securities in the high yield market.

HOW DID THE FUNDS PERFORM?
The performance of each Fund over the twelve-month period ended July 31, 2005,
as well as the performance of a comparative index, is shown in the accompanying

Over the 12-month reporting period, the returns of NSL and JFR outperformed the
CSFB Leveraged Loan Index. The total return of JRO underperformed this index
over the same period, which included the invest-up period for JRO's assets
raised through common and

     to maturity, and rated BBB or lower.

preferred share offerings, and in which that Fund incurred the costs of issuing
and underwriting its FundPreferred(R) shares.

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 high quality short-term interest
rates paid by the Funds on their FundPreferred(R) shares are lower than the
amount the Funds are earning from the lower quality adjustable-rate corporate
loans in their portfolios.

Other factors that benefited NSL during the 12 months ended July 31, 2005, were
the appreciation of credits from Aladdin Gaming and Anthony Crane Rental, as
well as positive contributions from investments in Western Industries and
Mirant. Conversely, the Fund's investment in MetalForming Technologies had a
negative impact on performance during the period.

JFR's performance also benefited from its investments in Aladdin and Anthony
Crane during the period. Meridian Automotive negatively affected the portfolio's
overall performance during the period.

As noted, the twelve-month period ended July 31, 2005, included the initial
invest-up of JRO's portfolio. Thus, it did not benefit from being fully invested
during the entire twelve months. In addition, the initial costs of issuing
FundPreferred(R) shares had a significantly negative effect on common share
returns during this period. JRO's portfolio also included Anthony Crane Rental,
which had a positive impact on the Fund's performance. There were no loans that
had a material negative impact on JRO's performance during the period.

                        Dividend and Share Price
                               INFORMATION



As noted, each of these Funds uses financial leverage in an effort to enhance
its dividend-paying capabilities. While this strategy adds volatility to a
Fund's net asset value (NAV) and share price, it generally works to enhance the
amount of income a Fund has to distribute to its common shareholders, as long as
the dividend rates the Fund pays to its preferred shareholders are less than the
interest rates the Fund receives from its portfolio of loans.

Since each of these Funds invests in adjustable rate loans, their income streams
typically can be expected to rise or fall over time to reflect the movement of
shorter-term interest rates. These rates generally were rising over this
twelve-month reporting period ended July 31, 2005, and this led to three monthly
dividend increases in NSL and two monthly dividend increases in JFR. JRO made
its initial monthly dividend declaration during this period, at an assertive
level which has been maintained since that time.

All of these Funds seek to pay stable dividends at rates that reflect each
Fund's past results, and projected future performance. During certain periods,
each Fund may pay dividends at a rate that may be more or less than the amount
of net investment income actually earned by the Fund during the period. If a
Fund has cumulatively earned more than it has paid in dividends, it holds the
excess in reserve as undistributed net investment income (UNII), which is part
of the Fund's NAV. Conversely, if a Fund has cumulatively paid dividends in
excess of its earnings, the excess constitutes negative UNII that is likewise
reflected in the Fund's NAV. Each Fund will, over time, pay all of its net
investment income as dividends to shareholders. As of July 31, 2005, NSL had a
positive UNII balance for both financial reporting and tax purposes, while JFR
and JRO had negative UNII balances for financial reporting purposes and positive
UNII balances for tax purposes.

As of July 31, 2005, NSL traded at a premium to its net asset value, while JFR
and JRO traded at discounts to their NAVs, as shown below.

Report of
   INDEPENDENT REGISTERED
   PUBLIC ACCOUNTING FIRM



THE BOARD OF TRUSTEES AND SHAREHOLDERS OF
NUVEEN SENIOR INCOME FUND
NUVEEN FLOATING RATE INCOME FUND
NUVEEN FLOATING RATE INCOME OPPORTUNITY FUND

We have audited the accompanying statements of assets and liabilities, including
the portfolio of investments, of Nuveen Senior Income Fund, Nuveen Floating Rate
Income Fund and Nuveen Floating Rate Income Opportunity Fund as of July 31,
2005, and the related statements of operations for the year then ended, the
statements of changes in net assets for the periods indicated therein, cash
flows for the year then ended, and the financial highlights for each of the
periods after July 31, 2003. These financial statements and financial highlights
are the responsibility of the Funds' management. Our responsibility is to
express an opinion on these financial statements and financial highlights based
on our audits. The financial highlights of the Nuveen Senior Income Fund for
each of the three years in the period ended July 31, 2003 were audited by other
auditors whose report dated September 18, 2003, expressed an unqualified opinion
on those financial highlights.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. We were
not engaged to perform an audit of the Funds' internal control over financial
reporting. Our audits included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Funds' internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall
financial statement presentation. Our procedures included confirmation of
securities owned as of July 31, 2005, by correspondence with the custodian,
selling or agent banks and brokers or by other appropriate auditing procedures
where replies from selling or agent banks or brokers were not received. We
believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of Nuveen
Senior Income Fund, Nuveen Floating Rate Income Fund and Nuveen Floating Rate
Income Opportunity Fund at July 31, 2005, the results of their operations for
the year then ended, changes in their net assets for the periods indicated
herein, cash flows for the year then ended, and their financial highlights for
each of the periods indicated herein, in conformity with U.S. generally accepted
accounting principles.

     (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, theactual remaining
          maturity of Senior Loans held in the Fund's portfolio may be
          substantially less than the stated maturities shown.

     **   Ratings (not covered by the report of independent registered public
          accounting firm) 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 July 31, 2005, this issue was non-income
          producing.
          
     (b)  At or subsequent to July 31, 2005, this issue was under the protection
          of the Federal Bankruptcy Court.

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

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

          by, or at the discretion 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, if still unknown, the borrower or counterparty will
          provide the Fund with the final weighted average coupon rate and
          maturity date.
       
    (PIK) In lieu of cash payment, interest accrued on "Payment in Kind"
          investment increases principal outstanding.

     (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.
         
     **   Ratings (not covered by the report of independent registered public
          accounting firm) 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 July 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 July
          31, 2005.
        
    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

          (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.

          **   Ratings (not covered by the report of independent registered
               public accounting firm) 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 July 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
               July 31, 2005.

          (d)  Portion of position represents an unfunded loan commitment
               outstanding at July 31, 2005.
                   
         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, if still unknown, the borrower or
               counterparty will provide the Fund with the final weighted
               average coupon rate and maturity date.
                  
         (PIK) In lieu of cash payment,  interest  accrued on "Payment in Kind"
               investment increases principal outstanding.

                        Notes to
                              FINANCIAL STATEMENTS







1. GENERAL INFORMATION AND SIGNIFICANT ACCOUNTING POLICIES
The funds (the "Funds") covered in this report and their corresponding Common
share New York Stock Exchange symbols are Nuveen Senior Income Fund (NSL),
Nuveen Floating Rate Income Fund (JFR) and Nuveen Floating Rate Income
Opportunity Fund (JRO). The Funds are registered under the Investment Company
Act of 1940, as amended, as closed-end management investment companies.

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 certain of the privately negotiated subordinated loans issued by
middle market companies. The pricing services, with input from Symphony Asset
Management, LLC (" Symphony"), an indirect wholly owned subsidiary of Nuveen,
and 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 senior loan.


                                       34



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 July 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 $23,542,500,
$55,571,250 and $29,000,000, respectively.

Investment Income
Interest income, which includes the amortization of premiums and accretion of
discounts for financial reporting purposes, is recorded on an accrual basis.
Interest income also includes paydown gains and losses on senior and
subordinated loans. Fee income consists primarily of amendment fees. Amendment
fees are earned as compensation for evaluating and accepting changes to the
original loan agreement and are recognized when received.

Professional Fees
Professional fees presented in the Statement of Operations consist of legal fees
incurred in the normal course of operations, audit fees, tax consulting fees
and, in some cases, workout expenditures. Workout expenditures are incurred in
an attempt to protect or enhance an investment, or to pursue other claims or
legal actions on behalf of Fund shareholders.

Income Taxes
Each Fund is a separate taxpayer for federal income tax purposes. Each Fund
intends to distribute substantially all net investment income and net capital
gains to shareholders and to otherwise comply with the requirements of
Subchapter M of the Internal Revenue Code applicable to regulated investment
companies. Therefore, no federal income tax provision is required.

Dividends and Distributions to Common Shareholders
Each Fund intends 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 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 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
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 fiscal year
ended July 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.

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 ($1,064,356 and $812,340, respectively) were recorded as reductions of the
proceeds from the sale of Common shares.

Costs incurred by Floating Rate Income (JFR) and Floating Rate Income
Opportunity (JRO) in connection with their offering of FundPreferred shares
($8,341,198 and $5,105,746, respectively) were recorded as a reduction to
paid-in surplus.

Indemnifications
Under the Funds' organizational documents, its Officers and Trustees are
indemnified against certain liabilities arising out of the performance of their
duties to the Funds. In addition, in the normal course of business, the Funds
enter into contracts that provide general indemnifications to other parties. The
Funds' maximum exposure under these arrangements is unknown as this would
involve future claims that may be made against the Funds that have not yet
occurred. However, the Funds have not had prior claims or losses pursuant to
these contracts and expect the risk of loss to be remote.

Use of Estimates
The preparation of financial statements in conformity with U.S. generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of increases and
decreases in net assets applicable to Common shares from operations during the
reporting period. Actual results may differ from those estimates.

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.

5. MANAGEMENT FEES AND OTHER TRANSACTIONS WITH AFFILIATES
The Funds' management fees are 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 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. As of August
31, 2005, the complex-level fee rate was .1896%.

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)

For the next $1 billion                                                                            .6375

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


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

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


     (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.

Notes to
        FINANCIAL STATEMENTS (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. Each Fund 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 July 31, 2005, Senior Income (NSL) had unfunded loan commitments
of $1,310,961, Floating Rate Income (JFR) had $5,476,623 while Floating Rate
Income Opportunity (JRO) had $2,438,221 in unfunded loan commitments.

7. SENIOR LOAN PARTICIPATION COMMITMENTS
With respect to the senior loans held in each Fund's portfolio, the Funds may:
1) invest in assignments; 2) act as a participant in primary lending syndicates;
or 3) invest in participations. If a Fund purchases a participation of a senior
loan interest, the Fund would typically enter into a contractual agreement with
the lender or other third party selling the participation, rather than directly
with the Borrower. As such, the Fund not only assumes the credit risk of the
Borrower, but also that of the Selling Participant or other persons
interpositioned between the Fund and the Borrower.

Senior Income (NSL) had the following participation commitments outstanding at

Floating Rate Income (JFR) and Floating Rate Income Opportunity (JRO) had no
such participation commitments outstanding at July 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 ($110 million
maximum) with Bank One's conduit financing agency, Falcon Asset Securitization
Corp. ("Falcon"), whose sole purpose is the issuance of high grade commercial
paper. Falcon uses the proceeds to make advances to Senior Income (NSL) and to
many other borrowers who comprise Falcon's total borrowing base. For the fiscal
year ended July 31, 2005, the average daily balance of borrowings under the
commercial paper program agreement was $103 million. The average interest rate
paid for funding and program usage fees on such borrowings was 2.47%.

Senior Income (NSL) has also entered into a $110 million liquidity facility. If
the facility is utilized, interest on the borrowings would be charged a variable
interest rate. An unused commitment fee of .095% on 102% of the unused portion
of the $110 million facility is charged. There were no borrowings under the
revolving credit agreement during the fiscal year ended July 31, 2005.

9. ANNOUNCEMENT REGARDING PARENT COMPANY OF ADVISER
In early April, 2005, The St. Paul Travelers Companies, Inc. ("St. Paul
Travelers"), which owned 79% of Nuveen, (A) completed a public offering of a
substantial portion of its equity stake in Nuveen, (B) sold Nuveen $200 million
of its Nuveen shares, (C) entered into an agreement with Nuveen to sell an
additional $400 million of its Nuveen shares on a "forward" basis with payment
for and settlement of these shares delayed for several months, and (D) entered
into agreements with two unaffiliated investment banking firms to sell an amount
equal to most or all of its remaining Nuveen shares for current payment but for
future settlement. Transactions (C) and (D) above were settled in late July,
which effectively reduced St. Paul Travelers' controlling stake in Nuveen and
was deemed an "assignment" (as defined in the 1940 Act) of the investment
management agreements between the Funds and the Adviser, which resulted in the
automatic termination of each agreement under the 1940 Act. In anticipation of
such deemed assignment, the Board of Trustees had approved new ongoing
investment management agreements for each Fund and the submission of those
agreements for approval by each respective Fund's shareholders, which
shareholder approval was received prior to the settlement of transactions (C)
and (D). The new ongoing management agreements took effect upon such settlement.

                                                                  2002).

                               MANAGEMENT AGREEMENT
                               APPROVAL PROCESS



At a meeting held on May 10-12, 2005, the Board of Trustees of the Funds,
including the independent Trustees, unanimously approved the Investment
Management Agreement between each Fund and NAM and the Sub-Advisory Agreement
between NAM and Symphony for each Fund (NAM and Symphony are each a "Fund
Adviser").

THE APPROVAL PROCESS
To assist the Board in its evaluation of an advisory contract with a Fund
Adviser, the independent Trustees received a report in adequate time in advance
of their meeting which outlined, among other things, the services provided by
the Fund Adviser; the organization of the Fund Adviser, including the
responsibilities of various departments and key personnel; the Fund's past
performance as well as the Fund's performance compared to funds of similar
investment objectives compiled by an independent third party (a "Peer Group") as
described below and with recognized and/or customized benchmarks (as
appropriate); the profitability of the Fund Adviser and certain industry
profitability analyses for advisers to unaffiliated investment companies; the
expenses of the Fund Adviser in providing the various services; the advisory
fees of the Fund Adviser, including comparisons of such fees with the management
fees of comparable funds in its Peer Group as well as comparisons of the Fund
Adviser's management fees with the fees the Fund Adviser assesses to other types
of investment products or accounts, if any; the soft dollar practices of the
Fund Adviser; and the expenses of each Fund, including comparisons of the Fund's
expense ratios (after any fee waivers) with the expense ratios of its Peer
Group. This information supplements that received by the Board throughout the
year regarding Fund performance, expense ratios, portfolio composition, trade
execution and sales activity.

In addition to the foregoing materials, independent legal counsel to the
independent Trustees provided, in advance of the meeting, a legal memorandum
outlining, among other things, the duties of the Trustees under the 1940 Act as
well as the general principles of relevant state law in reviewing and approving
advisory contracts; the requirements of the 1940 Act in such matters; an
adviser's fiduciary duty with respect to advisory agreements and compensation;
the standards used by courts in determining whether investment company boards of
directors have fulfilled their duties and factors to be considered by the board
in voting on advisory agreements.

At the Board meeting, NAM made a presentation to and responded to questions from
the Board. In addition, the independent Trustees noted that Symphony has also
previously made written or oral presentations to the Board providing it with the
opportunity to explain its investment strategies, discuss market conditions, and
highlight any material issues. Many of these presentations were part of site
visits by the Board throughout the year. After the presentations and after
reviewing the written materials, the independent Trustees met privately with
their legal counsel to review the Board's duties in reviewing advisory contracts
and consider the renewal of the advisory contract. It is with this background
that the Trustees considered each advisory contract (which includes sub-advisory
contracts) with a Fund Adviser. The independent Trustees, in consultation with
independent counsel, reviewed the factors set out in judicial decisions and SEC
directives relating to the renewal of advisory contracts. As outlined in more
detail below, the Trustees considered all factors they believed relevant with
respect to each Fund, including the following: (a) the nature, extent and
quality of the services to be provided by the Fund Adviser; (b) the investment
performance of the Fund and the Fund Adviser; (c) the costs of the services to
be provided and profits to be realized by the Fund Adviser and its affiliates
from the relationship with the Fund; (d) the extent to which economies of scale
would be realized as the Fund grows; and (e) whether fee levels reflect these
economies of scale for the benefit of Fund investors.

A. NATURE, EXTENT AND QUALITY OF SERVICES
In evaluating the nature, extent and quality of the respective Fund Adviser's
services, the Trustees reviewed information concerning the types of services
that a Fund Adviser or its affiliates provide and are expected to provide to the
Nuveen Funds; narrative and statistical information concerning the Fund's
performance record and how such performance compares to the Fund's Peer Group
and recognized benchmarks and/or customized benchmarks (as described in further
detail in Section B below); information describing the Fund Adviser's
organization and its various departments, the experience and responsibilities of
key personnel, and available resources. In the discussion of key personnel, the
Trustees received materials regarding the changes or additions in personnel of
the applicable Fund Adviser. The Trustees further noted the willingness of the
personnel of NAM to engage in open, candid discussions with the Board. The
Trustees further considered the quality of the Fund Adviser's investment process
in making portfolio management decisions, including any refinements or
improvements to the portfolio management processes, enhancements to technology
and systems that are available to portfolio managers, and any additions of new
personnel which may strengthen or expand the research and investment
capabilities of the Fund Adviser. In their review of the advisory contracts for
the fixed income funds, the Trustees also noted that Nuveen won the Lipper Award
for Best Fund Family: Fixed Income-Large Asset Class, for 2004. Given the
Trustees' experience with the Funds, other Nuveen funds and the Fund Advisers,
the Trustees noted that they were familiar with and continue to have a good
understanding of the organization, operations and personnel of the Fund
Advisers.


                                       50


In addition to advisory services, the independent Trustees considered the
quality of the administrative or non-advisory services provided. In this regard,
NAM provides the Funds with such administrative and other services (exclusive
of, and in addition to, any such services provided by others for the Funds) and
officers and other personnel as are necessary for the operations of the
respective Fund. In addition to investment management services, NAM and its
affiliates provide each Fund with a wide range of services, including: preparing
shareholder reports; providing daily accounting; providing quarterly financial
statements; overseeing and coordinating the activities of other service
providers; administering and organizing Board meetings and preparing the Board
materials for such meetings; providing legal support (such as helping to prepare
registration statements, amendments thereto and proxy statements and responding
to regulatory inquiries); and performing other Fund administrative tasks
necessary for the operation of the respective Fund (such as tax reporting and
fulfilling regulatory filing requirements). In addition, in evaluating the
administrative services, the Trustees considered, in particular, a Fund
Adviser's policies and procedures for assuring compliance with applicable laws
and regulations in light of the new SEC regulations governing compliance. The
Trustees noted NAM's focus on compliance and its compliance systems. In their
review, the Trustees considered, among other things, the additions of
experienced personnel to NAM's compliance group and modifications and other
enhancements to NAM's computer systems. In addition to the foregoing, the
Trustees also noted that NAM outsources certain services that cannot be
replicated without significant costs or at the same level of expertise. Such
outsourcing has been a beneficial and efficient use of resources by keeping
expenses low while obtaining quality services. Further, as the Funds utilize a
sub-adviser, the Trustees considered NAM's ability and procedures to monitor
Symphony's performance, business practices and compliance policies and
procedures. In this regard, the Trustees noted the role of NAM's investment
oversight committee, including its increased personnel, the responsibilities and
experience of the staff, and procedures to monitor sub-advisers, including the
use of site visits.

In addition to the above, in reviewing the variety of additional services that
NAM or its affiliates must provide to closed-end funds, such as the Funds, the
independent Trustees determined that Nuveen's commitment to supporting the
secondary market for the common shares of its closed-end funds is particularly
noteworthy. In this regard, the Trustees noted Nuveen's efforts to sponsor
numerous forums for analysts and specialists regarding the various Nuveen
closed-end funds, its creation of a new senior position dedicated to providing
secondary market support services and enhancing communications with investors
and analysts, and its advertising and media relations efforts designed to raise
investor and analyst awareness of the closed-end funds.

In evaluating the services of Symphony, the independent Trustees noted that the
Sub-Advisory Agreements were essentially agreements for portfolio management
services only and Symphony was not expected to supply other significant
administrative services to the Funds.

Based on their review, the Trustees found that, overall, the nature, extent and
quality of services provided (and expected to be provided) to the Fund under the
Investment Management Agreement or Sub-Advisory Agreement, as applicable, were
of a high level and were quite satisfactory.

B. THE INVESTMENT PERFORMANCE OF THE FUND AND FUND ADVISERS
As previously noted, the Board received a myriad of performance information
regarding each Fund and its Peer Group, if available. Among other things, the
Board received materials reflecting a Fund's historic performance, the Fund's
performance compared to its Peer Group (as available) and its performance
compared to recognized and/or customized benchmarks (as applicable). The
Trustees reviewed performance information including, among other things, total
return information compared with a Fund's Peer Group as well as recognized
and/or customized benchmarks (as appropriate) for the one-, three- and five-year
periods (as applicable) ending December 31, 2004. This information supplements
the Fund performance information provided to the Board at each of their
quarterly meetings. Based on their review, the Trustees determined that the
respective Fund's absolute and relative investment performance over time had
been satisfactory.

C. FEES, EXPENSES AND PROFITABILITY
    
1.   FEES AND EXPENSES 

     In evaluating the management fees and expenses that a Fund is expected to
     bear, the Trustees considered the Fund's current management fee structure,
     the sub-advisory fee arrangements and the Fund's expected expense ratios in
     absolute terms as well as compared with the fees and expense ratios of the
     unaffiliated funds in its Peer Group. The Trustees reviewed the financial
     information of the respective Fund Adviser, including its respective
     revenues, expenses and profitability. In reviewing fees, the Trustees,
     among other things, reviewed comparisons of the Fund's gross management
     fees (fees after fund-level and complex-wide level breakpoints but before
     reimbursements and fee waivers), net management fees (after breakpoints and
     reimbursements and fee waivers) and total expense ratios (before and after
     waivers) with those of the unaffiliated funds in its Peer Group and peer
     averages. In this regard, the Trustees noted that the relative ranking of
     the Nuveen funds on fees and expenses was aided by the significant level of
     fee reductions provided by the fund-level and complex-wide breakpoint
     schedules, and the fee waivers and reimbursements provided by Nuveen for
     certain funds launched since 1999. The complex-wide breakpoint schedule was
     instituted in 2004 and is described in further detail below in Section D
     entitled "Economies of Scale and Whether Fee Levels Reflect These Economies
     of Scale." In its review, the Trustees noted that all taxable closed-end
     exchange-traded Nuveen funds had net expense ratios below or within an
     acceptable range compared to peers.

2.   COMPARISONS WITH THE FEES OF OTHER CLIENTS

     The Trustees further compared the fees of NAM to the fees NAM or an
     affiliate thereof assessed for other types of clients (such as separate
     managed accounts as well as fees charged on funds that are not offered by
     Nuveen but are sub-advised by one of Nuveen's investment management teams).
     With respect to separately managed accounts, the advisory fees to such
     separate managed accounts are generally lower than those charged to the
     comparable Fund. The Trustees noted, however, the additional services that
     are provided and the costs incurred by Nuveen in managing and operating
     registered investment companies, such


                                       51






        ANNUAL INVESTMENT MANAGEMENT
        AGREEMENT APPROVAL PROCESS (continued)


     as the Funds, compared to individually managed separate accounts. For
     instance, as described above, NAM and its affiliates provide numerous
     services to the Funds including, but not limited to, preparing shareholder
     reports; providing daily accounting; preparing quarterly financial
     statements; overseeing and coordinating the activities of other service
     providers; administering and organizing Board meetings and preparing the
     Board materials for such meetings; providing legal support; and
     administering all other aspects of the Fund's operations. Further, the
     Trustees noted the increased compliance requirements for funds in light of
     new SEC regulations and other legislation. These services are generally not
     required to the same extent, if at all, for separate accounts. In addition
     to the differences in services, the Trustees also considered, among other
     things, the differences in product distribution, investor profiles and
     account sizes. Accordingly, the Trustees believe that the nature and number
     of services provided to operate a Fund merit the higher fees than those to
     separate managed accounts.

     In considering the fees of Symphony, the Trustees also considered the 
     pricing schedule Symphony charges for similar investment management 
     services for other fund sponsors or clients. The Trustees also compared the
     sub-advisory fees to the significantly higher fees assessed to hedge funds 
     by Symphony. Generally, the sub-advisory fees were at the lower end of the 
     Symphony's fee schedule.

3.   PROFITABILITY OF ADVISERS

     In conjunction with its review of fees, the Trustees also considered the
     profitability of NAM (which incorporated Nuveen's wholly-owned
     subsidiaries, such as Symphony). The Trustees reviewed the respective Fund
     Adviser's revenues, expenses and profitability margins (on both a pre-tax
     and after-tax basis). In reviewing profitability, the Trustees recognized
     that one of the most difficult issues in determining profitability is
     establishing a method of allocating expenses. Accordingly, the Trustees
     reviewed a Fund Adviser's assumptions and methodology of allocating
     expenses. In this regard, the methods of allocation used appeared
     reasonable but the Board noted the inherent limitations in allocating costs
     among various advisory products. The Trustees also recognized that
     individual fund or product line profitability of other advisers is
     generally not publicly available. Further, profitability may be affected by
     numerous factors including the types of funds managed, expense allocations,
     business mix, etc. and therefore comparability of profitability is somewhat
     limited. Nevertheless, to the extent available, the Trustees considered the
     respective Fund Adviser's profit margin compared to the profitability of
     various publicly-traded investment management companies and/or investment
     management companies that publicly disclose some or all of their financial
     results compiled by three independent third-party service providers. The
     Trustees also reviewed the revenues, expenses and profit margins of various
     unaffiliated advisory firms with similar amounts of assets under management
     for the last year prepared by NAM. Based on their review, the Trustees were
     satisfied that each Fund Adviser's level of profitability from its
     relationship with each Fund was reasonable in light of the services
     provided.

     In evaluating the reasonableness of the compensation, the Trustees also
     considered any other revenues paid to a Fund Adviser as well as any
     indirect benefits (such as soft dollar arrangements, if any) the Fund
     Adviser and its affiliates are expected to receive that are directly
     attributable to their management of the Funds, if any. See Section E below
     for additional information. Based on their review of the overall fee
     arrangements of the applicable Fund, the Trustees determined that the
     advisory fees and expenses of the respective Fund were reasonable.

D. ECONOMIES OF SCALE AND WHETHER FEE LEVELS REFLECT THESE ECONOMIES OF SCALE
In reviewing the compensation, the Trustees have long understood the benefits of
economies of scale as the assets of a fund grow and have sought to ensure that
shareholders share in these benefits. One method for shareholders to share in
economies of scale is to include breakpoints in the advisory fee schedules that
reduce fees as fund assets grow. Accordingly, the Trustees received and reviewed
the schedules of advisory fees for each Fund, including fund-level breakpoints
thereto. In addition, after lengthy negotiations with management, the Board in
May, 2004 approved a complex-wide fee arrangement pursuant to which fees of the
funds in the Nuveen complex, including the Funds, are reduced as the assets in
the fund complex reach certain levels. The complex-wide fee arrangement was
introduced on August 1, 2004 and the Trustees reviewed data regarding the
reductions of fees for the Funds for the period of August 1, 2004 to December
31, 2004. In evaluating the complex-wide fee arrangement, the Trustees
considered, among other things, the historic and expected fee savings to
shareholders as assets grow, the amount of fee reductions at various asset
levels, and that the arrangement would extend to all Funds in the Nuveen
complex. The Trustees also considered the impact, if any, the complex-wide fee
arrangement may have on the level of services provided. Based on their review,
the Trustees concluded that the breakpoint schedule and complex-wide fee
arrangement currently was acceptable and desirable in providing benefits from
economies of scale to shareholders.


                                       52





E. INDIRECT BENEFITS
In evaluating fees, the Trustees also considered any indirect benefits or
profits the respective Fund Adviser or its affiliates may receive as a result of
its relationship with each Fund. In this regard, the Trustees considered any
benefits from soft dollar arrangements. The Trustees noted that although NAM
manages a large amount of assets, it has very little, if any, brokerage to
allocate. This is due to the fact that NAM typically manages the portfolios of
the municipal funds in the Nuveen complex and municipal bonds generally trade on
a principal basis. Accordingly, NAM does not currently have any soft dollar
arrangements and does not pay excess brokerage commissions (or spreads on
principal transactions) in order to receive research services. The Trustees also
considered the soft dollar arrangements of the sub-adviser. The Trustees noted
that Symphony also does not use soft dollar arrangements.

In addition to soft dollar arrangements, the Trustees also considered any other
revenues, if any, received by NAM or its affiliates. In this regard, for Nuveen
funds with outstanding preferred shares and new closed-end funds, the Trustees
also considered revenues received by Nuveen for serving as agent for
broker-dealers at its preferred trading desk and for acting as co-manager in the
initial public offering of new closed-end exchange-traded funds.

F. OTHER CONSIDERATIONS
Nuveen, until recently, was a majority owned subsidiary of St. Paul Travelers
Companies, Inc. ("St. Paul"). As noted, St. Paul earlier this year announced its
intention to divest its equity stake in Nuveen. Nuveen is the parent of NAM.
Pursuant to a series of transactions, St. Paul had begun to reduce its interest
in Nuveen which would ultimately result in a change of control of Nuveen and
therefore NAM. As mandated by the 1940 Act, such a change in control would
result in an assignment of the Investment Management Agreement with NAM and the
automatic termination of such agreement. Accordingly, the Board also considered
the approval of a New Investment Management Agreement with each Fund in light
of, and which would take effect upon, the anticipated change of control. More
specifically, the Board considered for each Fund a New Investment Management
Agreement on substantially identical terms to the existing Investment Management
Agreement, to take effect after the change of control has occurred and the
contract has been approved by Fund shareholders. In its review, the Board
considered whether the various transactions necessary to divest St. Paul's
interest will have an impact on the various factors they considered in approving
NAM, such as the scope and quality of services to be provided following the
change of control. In reviewing the St. Paul transactions, the Board considered,
among other things, the impact, if any, on the operations and organizational
structure of NAM; the possible benefits and costs of the transactions to the
respective Fund; the potential implications of any arrangements used by Nuveen
to finance certain of the transactions; the ability of NAM to perform its duties
after the transactions; whether a Fund's fee structure or expense ratio would
change; any changes to the current practices of the respective Fund; any changes
to the terms of the advisory agreement; and any anticipated changes to the
operations of NAM. Based on its review, the Board determined that St. Paul's
divestiture would not affect the nature and quality of services provided by NAM,
the terms of the Investment Management Agreement, including the fees thereunder,
and would not materially affect the organization or operations of NAM.
Accordingly, the Board determined that their analysis of the various factors
regarding their approval of NAM would continue to apply after the change of
control.

In addition to the foregoing, a change in control of NAM may be deemed an
assignment of the Sub-Advisory Agreement between NAM and Symphony. Further,
Symphony is a wholly-owned subsidiary of Nuveen. Accordingly, the change of
control of Nuveen would also result in a change of control of such sub-adviser
resulting in the automatic termination of its existing Sub-Advisory Agreements.
The Board therefore considered approval of a New Sub-Advisory Agreement with
Symphony in light of the anticipated change of control. More specifically, the
Board considered approval of each New Sub-Advisory Agreement on substantially
identical terms as the respective Original Sub-Advisory Agreement, to take
effect after the change of control has occurred and the agreement has been
approved by Fund shareholders. In reviewing the impact of the St. Paul divesture
on Symphony, the Board considered the same factors as outlined previously with
respect to their review of NAM. As with NAM, the Board concluded that the St.
Paul divestiture would not affect the nature and quality of services provided by
Symphony, the terms of the Sub-Advisory Agreement, including the fees paid
thereunder, and would not materially affect the organization or operations of
Symphony. Accordingly, the Board determined that their analysis of the various
factors regarding their review and approval of Symphony, as sub-adviser, would
continue to apply following the change in control.

G. APPROVAL
The Trustees did not identify any single factor discussed previously as
all-important or controlling. The Trustees, including a majority of independent
Trustees, concluded that the terms of the Investment Management and Sub-Advisory
Agreements were fair and reasonable, that the respective Fund Adviser's fees are
reasonable in light of the services provided to each Fund, that the renewal of
the NAM Investment Management Agreement and each Sub-Advisory Agreement should
be approved, and that the new, post-change of control NAM Investment Management
Agreement and the Sub-Advisory Agreements be approved and recommended to
shareholders.

                             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 tax-free
compounding.

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

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

HOW SHARES ARE PURCHASED
The shares you acquire by reinvesting will either be purchased on the open
market or newly issued by the Fund. If the shares are trading at or above net
asset value at the time of valuation, the Fund will issue new shares at the
greater of the net asset value or 95% of the then-current market price. If the
shares are trading at less than net asset value, shares for your account will be
purchased on the open market. Dividends and distributions received to purchase
shares in the open market will normally be invested shortly after the dividend
payment date. No interest will be paid on dividends and distributions awaiting
reinvestment. Because the market price of the shares may increase before
purchases are completed, the average purchase price per share may exceed the
market price at the time of valuation, resulting in the acquisition of fewer
shares than if the dividend or distribution had been paid in shares issued by
the Fund. A pro rata portion of any applicable brokerage commissions on open
market purchases will be paid by Plan participants. These commissions usually
will be lower than those charged on individual transactions.

FLEXIBLE
You may change your distribution option or withdraw from the Plan at any time,
should your needs or situation change. Should you withdraw, you can receive a
certificate for all whole shares credited to your reinvestment account and cash
payment for fractional shares, or cash payment for all reinvestment account
shares, less brokerage commissions and a $2.50 service fee.

You can reinvest whether your shares are registered in your name, or in the name
of a brokerage firm, bank, or other nominee. Ask your investment advisor if his
or her firm will participate on your behalf. Participants whose shares are
registered in the name of one firm may not be able to transfer the shares to
another firm and continue to participate in the Plan.

The Fund reserves the right to amend or terminate the Plan at any time. Although
the Fund reserves the right to amend the Plan to include a service charge
payable by the participants, there is no direct service charge to participants
in the Plan at this time.

   Other Useful
          INFORMATION

In April, 2005, The St. Paul Travelers Companies, Inc. ("St. Paul Travelers")
sold the majority of its controlling equity interest in Nuveen Investments, Inc.
("Nuveen") to the general public. Nuveen is the parent of Nuveen Asset
Management ("NAM"), which is each Fund's investment manager. This sale was
deemed to be an "assignment" of the investment management agreement between each
Fund and NAM and, if applicable, of the sub-advisory agreement between NAM and
the Fund's sub-adviser. As required by law, the shareholders of each Fund were
asked to approve a new investment management agreement and, if applicable, a new
subadvisory agreement that reflected this change in ownership. The shareholders
of each Fund voted this approval at a Shareholders' Meeting on July 26, 2005.
There were no changes to the investment objectives or management of any Fund as
a result of these actions.

the annual CEO certification as required by Section 303A.12(a) of the NYSE
Listed Company Manual. Each Fund has filed with the Securities and Exchange
Commission the certification of its Chief Executive Officer and Chief Financial
Officer required by Section 302 of the Sarbanes-Oxley Act.

GLOSSARY OF TERMS USED IN THIS REPORT

AVERAGE ANNUAL TOTAL RETURN: This is a commonly used method to express an
investment's performance over a particular, usually multi-year time period. It
expresses the return that would have been necessary each year to equal the
investment's actual cumulative performance (including change in NAV or market
price and reinvested dividends and capital gains distributions, if any) over the
time period being considered.

MARKET YIELD (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.

As of the end of the period covered by this report, the registrant has adopted a

ITEM 3. AUDIT COMMITTEE FINANCIAL EXPERT.

The registrant's Board of Directors or Trustees determined that the registrant

ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES.



                            Nuveen Senior Income Fund

The following tables show the amount of fees that Ernst & Young LLP, the Fund's
auditor, billed to the Fund during the Fund's last two full fiscal years. For
engagements with Ernst & Young LLP entered into on or after May 6, 2003, the
Audit Committee approved in advance all audit services and non-audit services
that Ernst & Young LLP provided to the Fund, except for those non-audit services
that were subject to the pre-approval exception under Rule 2-01 of Regulation
S-X (the "pre-approval exception"). The pre-approval exception for services
provided directly to the Fund waives the pre-approval requirement for services
other than audit, review or attest services if: (A) the aggregate amount of all
such services provided constitutes no more than 5% of the total amount of
revenues paid by the Fund to its accountant during the fiscal year in which the
services are provided; (B) the Fund did not recognize the services as non-audit
services at the time of the engagement; and (C) the services are promptly
brought to the Audit Committee's attention, and the Committee (or its delegate)
approves the services before the audit is completed.

The Audit Committee has delegated certain pre-approval responsibilities to its
Chairman (or, in his absence, any other member of the Audit Committee).

The above "All Other Fees" are fees paid to audit firms to perform agreed upon
procedures required by the rating agencies to rate fund preferred shares. The
above "Tax Fees" were billed for professional services for tax advice, tax
compliance, and tax planning.

                 SERVICES THAT THE FUND'S AUDITOR BILLED TO THE
                  ADVISER AND AFFILIATED FUND SERVICE PROVIDERS

The following tables show the amount of fees billed by Ernst & Young LLP to
Nuveen Asset Management ("NAM" or the "Adviser"), and any entity controlling,
controlled by or under common control with NAM ("Control Affiliate") that
provides ongoing services to the Fund ("Affiliated Fund Service Provider"), for
engagements directly related to the Fund's operations and financial reporting,
during the Fund's last two full fiscal years.

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

The above "Tax Fees" are primarily fees billed to the Adviser for Fund tax
return preparation.

                               NON-AUDIT SERVICES

The following table shows the amount of fees that Ernst & Young LLP billed
during the Fund's last two full fiscal years for non-audit services. For
engagements entered into on or after May 6, 2003, the Audit Committee is
required to pre-approve non-audit services that Ernst & Young LLP provides to
the Adviser and any Affiliated Fund Services Provider, if the engagement related
directly to the Fund's operations and financial reporting (except for those
subject to the de minimis exception described above). The Audit Committee
requested and received information from Ernst & Young LLP about any non-audit
services that Ernst & Young LLP rendered during the Fund's last fiscal year to
the Adviser and any Affiliated Fund Service Provider. The Committee considered
this information in evaluating Ernst & Young LLP's independence.



Fiscal Year Ended                                                   Total Non-Audit Fees

The above "Non-Audit Fees billed to Adviser" for 2005 include "Tax-Fees" billed
to Adviser in the amount of $282,575 from previous table.

Audit Committee Pre-Approval Policies and Procedures. Generally, the audit
committee must approve (i) all non-audit services to be performed for the Fund

ITEM 7.  DISCLOSURE OF PROXY VOTING POLICIES AND PROCEDURES FOR CLOSED-END

In the rare event that a municipal issuer held by the Fund were to issue a proxy
or that the Fund were to receive a proxy issued by a cash management security,
the Adviser would either engage an independent third party to determine how the
proxy should be voted or vote the proxy with the consent, or based on the
instructions, of the Fund's Board of Directors or Trustees or its
representative. In the case of a conflict of interest, the proxy would be
submitted to the applicable Fund's Board to determine how the proxy should be
voted. A member of the Adviser's legal department would oversee the
administration of the voting, and ensure that records were maintained in
accordance with Rule 204-2(c)(2) under the Investment Advisers Act of 1940 (17
CFR 275.204-2(c)(2)), reports were filed with the SEC on Form N-PX, and the
