                    NR   Not rated.

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

                    **   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.

                    (1)  Senior Loans in which the Fund invests generally pay
                         interest at rates which are periodically redetermined
                         by reference to a base lending rate plus a premium.
                         These base lending rates are generally (i) the lending
                         rate offered by one or more major European banks, such
                         as the London Inter-Bank Offered Rate ("LIBOR"), (ii)
                         the prime rate offered by one or more major United
                         States banks, and (iii) the certificate of deposit
                         rate. Senior loans are generally considered to be
                         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.

                    (a)  At or subsequent to April 30, 2002, this issue was
                         non-income producing.

                    (b)  At April 30, 2002, this issue was under the protection
                         of the federal bankruptcy court.

                    (c)  Position has a zero cost basis and was acquired as part
                         of a workout program.

                    (d)  At May 29, 2002, this issue emerged from bankruptcy
                         proceedings.

                     +   Borrowings payable as a percentage of total gross
                         assets is 27.2%.

Notes to Financial Statements (Unaudited)

1. GENERAL INFORMATION AND SIGNIFICANT ACCOUNTING POLICIES
Nuveen Senior Income Fund (the "Fund") is a non-diversified, closed-end
management investment company registered under the Investment Company Act of
1940, as amended. The Fund is listed on the New York Stock Exchange and trades
under the ticker symbol "NSL". The Fund was organized as a Massachusetts
business trust on August 13, 1999.

The Fund seeks to provide a high level of current income, consistent with
preservation of capital by investing primarily in senior secured loans whose
interest rates float or adjust periodically based on a benchmark interest rate
index. The Fund seeks to increase the income available for distribution to
Common Shareholders by utilizing financial leverage.

The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements in accordance with
accounting principles generally accepted in the United States.


Investment Valuation
The prices of senior loans and bonds in the Fund's investment portfolio are
provided by an independent pricing service approved by the Fund's Board of
Trustees. The pricing service provider typically values senior loans and bonds
at the mean of the highest bona fide bid and lowest bona fide ask prices when
current quotations are readily available. Senior loans and bonds for which
current quotations are not readily available are valued at fair value using a
wide range of market data and other information and analysis, including credit
characteristics considered relevant by such pricing service providers to
determine valuations. The Board of Trustees of the Fund has approved procedures
which permit Nuveen Senior Loan Asset Management Inc. (the "Adviser"), a wholly
owned subsidiary of The John Nuveen Company, to override the price provided by
the independent pricing service. There were no price overrides during the nine
months ended April 30, 2002. Short-term investments which mature within 60 days
are valued at amortized cost, which approximates market value.

The senior loans in which the Fund invests are generally not listed on any
exchange and the secondary market for those senior loans is comparatively
illiquid relative to markets for other fixed income securities. Because of the
comparatively illiquid markets, the value of a senior loan may differ
significantly from the value that would have been used had there been an active
market for that senior loan.


Investment Transactions
Investment transactions are recorded on a trade date basis.


Investment Income
Interest income is determined on the basis of interest accrued, adjusted for
amortization of premiums and accretion of discounts. Facility fees on senior
loans purchased are treated as market discounts. Market premiums and discounts
are amortized over the expected life of each respective borrowing. Fees consist
primarily of amendment fees. Amendment fees are earned as compensation for
evaluating and accepting changes to the original credit agreement.


Income Taxes
The Fund intends to comply with the requirements of the Internal Revenue Code
applicable to regulated investment companies and to distribute substantially all
of its net investment income to its shareholders. Therefore, no federal income
tax provision is required.


Dividends and Distributions to Shareholders
The Fund intends to declare and pay monthly distributions to Common
Shareholders. Generally, payment is made or reinvestment is credited to
shareholder accounts on the first business day after month-end. 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.



Notes to Financial Statements (Unaudited) (continued)


Distributions to shareholders of net investment income, and net realized capital
gains 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 accounting principles generally accepted in the United
States. Accordingly, temporary over-distributions as a result of these
differences may occur and will be classified as either distributions in excess
of net investment income and/or distributions in excess of net realized gains
from investment transactions, where applicable. Permanent differences between
financial and tax basis reporting have been identified and appropriately
reclassified. During the nine months ended April 30, 2002, permanent differences
relating to expenses which are not deductible for tax purposes totaling $11,773
were reclassified from undistributed net investment income to capital.


Taxable Auctioned Preferred Shares
The Fund has issued and outstanding 1,840 Series TH $25,000 stated value Taxable
Auctioned Preferred Shares. The dividend rate paid on the Taxable Auctioned
Preferred Shares may change every 28 days, as set by the auction agent.


Derivative Financial Instruments
The Fund may invest in certain derivative financial instruments including
futures, forward, swap and option contracts, and other financial instruments
with similar characteristics. Although the Fund is authorized to invest in such
financial instruments, and may do so in the future, it did not make any such
investments during the nine months ended April 30, 2002.


Use of Estimates
The preparation of financial statements in conformity with accounting principles
generally accepted in the United States 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.


Change in Accounting Policy
Effective August 1, 2001, the Fund adopted the provisions of the new AICPA Audit
and Accounting Guide for Investment Companies (the "Guide"). As required by the
Guide, the Fund began presenting paydown gains and losses on mortgage and
asset-backed securities as interest income. Prior to adopting the new Guide, the
Fund presented paydown gains and losses on mortgage and asset-backed securities
together with realized gain/loss from investment transactions. This change in
accounting has no effect on the total net assets applicable to Common Shares or
the Common Share net asset value of the Fund. Interest income increased by
$54,783 and realized gain/loss decreased by the same amount for the nine months
ended April 30, 2002.

The Statement of Changes in Net Assets and Financial Highlights for the prior
periods have not been restated to reflect this change in presentation.

Classification and Measurement of Redeemable Securities
Effective August 1, 2001, the Fund adopted the classification requirement of
EITF D-98, Classification and Measurement of Redeemable Securities. EITF D-98
requires that Preferred shares, at liquidation value, be presented separately in
the Statement of Assets and Liabilities. Accordingly, certain reclassifications
have been made to the financial statements and financial highlights for all
prior periods presented. The adoption of EITF D-98 had no impact on the Fund's
Common share net asset value.

2. FUND SHARES
During the nine months ended April 30, 2002, 30,737 Common Shares were issued
to shareholders due to reinvestment of distributions.

During the fiscal year ended July 31, 2001, 81,022 Common Shares were issued to
shareholders due to reinvestment of distributions.


3. DISTRIBUTIONS TO COMMON SHAREHOLDERS
The Fund declared a dividend distribution of $.0490 per Common Share from its
net investment income which was paid on June 3, 2002, to shareholders of
record on May 15, 2002.


4. INVESTMENT TRANSACTIONS
Purchases and sales of investments (excluding short-term investments) during the
nine months ended April 30, 2002, aggregated $116,062,654 and $144,984,067,
respectively.


At April 30, 2002, the cost of investments owned for federal income tax
purposes was $429,747,127.



5. UNREALIZED APPRECIATION (DEPRECIATION)
At April 30, 2002, net unrealized depreciation of investments for federal
income tax purposes aggregated $52,995,948 of which $4,058,959 related to
appreciated investments and $57,054,907 related to depreciated investments.


6. MANAGEMENT FEES AND OTHER TRANSACTIONS WITH AFFILIATES
Under the Fund's investment management agreement with the Adviser, the Fund pays
an annual management fee, payable monthly, of .8500 of 1%, which is based upon
the average daily managed assets of the Fund. "Managed assets" shall mean the
average daily gross asset value of the Fund, minus the sum of the Fund's accrued
and unpaid dividends on any outstanding Taxable Auctioned Preferred Shares and
accrued liabilities (other than the principal amount of any borrowings incurred,
commercial paper or notes issued by the Fund and the liquidation preference of
any outstanding Taxable Auctioned Preferred Shares).

The Adviser has agreed to waive part of its management fees or reimburse certain
expenses of the Fund in an amount equal to .45% of the average daily managed
assets for the period October 29, 1999 (commencement of operations) through
October 31, 2004, .35% of the average daily managed assets for the year ended
October 31, 2005, .25% of the average daily managed assets for the year ended
October 31, 2006, .15% of the average daily managed assets for the year ended
October 31, 2007, .10% of the average daily managed assets for the year ended
October 31, 2008, and .05% of the average daily managed assets for the year
ended October 31, 2009. The Adviser has not agreed to reimburse the Fund for any
portion of its fees and expenses beyond October 31, 2009.

The management fee compensates the Adviser for overall investment advisory and
administrative services and general office facilities. The Fund pays no
compensation directly to those of its Trustees who are affiliated with the
Adviser or to their officers, all of whom receive remuneration for their
services to the Fund from the Adviser.


7. COMMITMENTS
Pursuant to the terms of certain of the Variable Rate Senior Loan agreements,
the Fund had unfunded loan commitments of approximately $2 million as of April
30, 2002. The Fund generally will maintain with its custodian short-term
investments and/or cash having an aggregate value at least equal to the amount
of unfunded loan commitments.

8. SENIOR LOAN PARTICIPATION COMMITMENTS
The Fund invests primarily in assignments, participations, or acts as a party to
the primary lending syndicate of a Variable Rate Senior Loan interest to
corporations, partnerships, and other entities. If the 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, but not with the borrower directly. As such, the Fund assumes the
credit risk of the Borrower, Selling Participant or other persons
interpositioned between the Fund and the Borrower. There were no such
participation commitments as of April 30, 2002.

9. BORROWINGS
In accordance with its 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.

On May 23, 2000, the Fund entered into a $150 million commercial paper program
with Nuveen Funding, L.L.C., a Delaware limited liability company whose sole
purpose is the issuance of commercial paper. Nuveen Funding, L.L.C. has the
authority to issue a maximum of $150 million of commercial paper, at a discount,
with maturities of up to 180 days, the proceeds of which are used to make
advances to the Fund. This line of credit is secured by the assets of the Fund.
For the nine months ended April 30, 2002, the average daily balance of
borrowings under the commercial paper program agreement was approximately $103
million with an average interest rate of 2.52%.

The Fund has entered into a $155 million revolving credit agreement with
Deutsche Bank AG which expires May 2003. Interest on borrowings is charged at a
rate of either the Fed Funds rate plus .50%, LIBOR plus .50% or the Prime Rate.
An unused commitment fee of .125% is charged on the unused portion of the
facility. During the nine months ended April 30, 2002, there were no
borrowings under the revolving credit agreement and, therefore, there was no
outstanding revolving credit balance at April 30, 2002.

Cash paid for interest during the nine months ended April 30, 2002, was
$2,112,172.
