Income Fund Inc. for the fiscal year ended September 30, 2001.


Q&A WITH PORTFOLIO MANAGER

FRANK BIONDO
================================================================================
[GRAPHIC OMITTED]

HOW DID THE FUND PERFORM DURING THE FISCAL YEAR RELATIVE TO ITS PEERS?

For the fiscal year ended September 30, 2001, the Fund advanced 8.60% based on
net asset value. In contrast, the Lipper General Municipal Debt Funds
(Leveraged) Median returned 12.97%. The Fund underperformed its peer group on a
net asset basis primarily due to its short duration versus its peers. Because
the Fund maintained a higher cash or short-term position, we missed some of the
upside potential afforded by the steep yield curve. We continue to move toward a
more neutral position as opportunities present themselves and will continue to
look for opportunities that are created due to the inefficient nature of the
municipal market.

WHAT MARKET FACTORS AFFECTED THE FUND'S PERFORMANCE?

The Federal Reserve's ("The Fed's") crusade to prop up the weakening economy by
reducing the Fed Funds rate from 6.5% at the beginning of the year to 3.0% at
the end of September 2001 caused the steepest municipal yield curve from two to
30 years since 1993. This caused the short end of the yield curve to rally
considerably since the beginning of the year. The rate cuts also prompted a
flurry of year-to-date municipal bond activity, as new issuance increased 34.2%
and refunding of existing debt was up over 227% since January 1, 2001.

GIVEN THE NATION'S ECONOMIC SLOWDOWN, DID YOU MAKE ANY CHANGES TO THE FUND'S
INVESTMENTS DURING THE PAST SIX MONTHS?

We did not make any significant credit changes to the Fund, but we made
structural yield curve positioning changes due to the overall change in the
yield curve. Our credit research has long anticipated that there would be a
period of recession after such a long period of growth. We continue to monitor
the credits in the portfolio for any deterioration in the credit quality. From a
credit perspective, we continue to monitor and vigorously stress-test all the
securities in the portfolio to ensure credit stability.

DID THE ENERGY CRISIS IN CALIFORNIA LAST SPRING OR SEPTEMBER'S TERRORIST ATTACKS
HAVE AN EFFECT ON THE FUND'S PERFORMANCE?

The California crisis has not had a significant impact on the Fund's
performance, as our exposure to the California market has been very small. Our
research team has maintained a cautious outlook on the California market since
January and we have been reluctant to add to our exposure in the state.
California credits have traded at historically high levels since the beginning
of the year versus other state credits, so we feel that better opportunities are
available in other state credits.

The September 11 attacks did have an impact, not only on the economy as a whole,
but on the municipal market. We saw a temporary interruption in market liquidity
due to the tragic loss of life suffered by Cantor Fitzgerald, a prominent bond
broker. The Fund, however, was not damaged as badly as it could have been, since
our exposure to hotels, airlines and airport credits is a small percentage of
the portfolio. In particular, our exposure to airport credits has been very
selective. However, we believe that there is value in selective airport revenue
bonds. Thus, we will look to add to our general airport revenue bond exposure as
opportunities present themselves.

AFTER THE CALIFORNIA CRISIS, IS THERE ANY CONCERN ABOUT POWER-RELATED SECURITIES
IN THE PORTFOLIO?

We believe the Fund's exposure to power related securities is well diversified
across many different credits, so we do not have major concerns in this area.

HAVE RECENT MARKET CONDITIONS PRESENTED BUYING OR SELLING OPPORTUNITIES?

The recent market conditions have presented us with structural opportunities,
such as buying premium coupon bonds with short calls in the 14 to 20-year range.
From a credit perspective, widening spreads between general airport revenue
bonds and high-grade bonds have presented a buying opportunity. Our research
team has identified those airport credits that should withstand the
deterioration in the economy and in the airline industry.

HOW IS THE FUND POSITIONED TO ACCOMMODATE THE UNCERTAIN ECONOMIC AND MARKET
ENVIRONMENT?

We look at yield curve mispricings to focus on the ideal overall maturity by
using an internal technical analysis approach. Our top-down approach helps us
determine sector attractiveness and the bottom-up approach is used to determine
security attractiveness. Given our long-term investment objective and leverage,
the optimal structural positioning of the Fund is to continue to look for
premium coupons in the 14 to 20-year range of the yield curve. We will continue
to look for credit situations that present the most value on a relative basis.
Since the hospital sector may be affected, as the potential exists for lower
Medicaid and Medicare payments while the country spends money on security
concerns, we will keep a cautious outlook in this sector. The defensive
positioning should help us over the long haul.

WHAT IS AHEAD FOR THE ECONOMY AND MUNI MARKET?

Municipal issuance and refunding issuance should continue to be robust.
Year-to-date refundings have surged past most estimates and, given the supply
and demand dynamics of many municipal issuers, we should witness an increase in
overall issuance next year compared to this year. Given the slowing economy, we
will continue to avoid those states and credits most susceptible to a
deteriorating economic environment. We will however, focus and search out
opportunistic relative value situations.

NOTES TO FINANCIAL STATEMENTS


ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

     Investment Grade Municipal Income Fund Inc. (the "Fund") was incorporated
in Maryland on August 6, 1992, and is registered with the Securities and
Exchange Commission as a closed-end diversified management investment company.
The Fund's investment objective is to achieve a high level of current income
that is exempt from federal income tax, consistent with the preservation of
capital.

     The preparation of financial statements in accordance with accounting
principles generally accepted in the United States requires Fund management to
make estimates and assumptions that affect the reported amounts and disclosures
in the financial statements. Actual results could differ from those estimates.
The following is a summary of significant accounting policies:

     VALUATION OF INVESTMENTS--The Fund calculates its net asset value based on
the current market value, where available, for its portfolio securities. The
Fund normally obtains market values for its securities from independent pricing
sources and broker-dealers. Independent pricing sources may use reported last
sale prices, current market quotations or valuations from computerized "matrix"
systems that derive values based on comparable securities. Securities traded in
the over-the-counter ("OTC") market and listed on The Nasdaq Stock Market, Inc.
("Nasdaq") normally are valued at the last sale price on Nasdaq prior to
valuation. Other OTC securities are valued at the last bid price available prior
to valuation. If a market value is not available from an independent pricing
source for a particular security, that security is valued at fair value as
determined in good faith by or under the direction of the Fund's board of
directors (the "Board"). The amortized cost method of valuation, which
approximates market value, generally is used to value short-term debt
instruments with sixty days or less remaining to maturity, unless the Board
determines that this does not represent fair value.

     INVESTMENT TRANSACTIONS AND INVESTMENT INCOME--Investment transactions are
recorded on the trade date. Realized gains and losses from investment
transactions are calculated using the identified cost method. Interest income is
recorded on an accrual basis. Discounts are accreted and premiums are amortized
as adjustments to interest income and the identified cost of investments.

     DIVIDENDS AND DISTRIBUTIONS--The Fund intends to pay monthly dividends to
common shareholders at a level rate that over time will result in the
distribution of all of the Fund's net investment income remaining after the
payment of dividends on any outstanding preferred stock. Dividends and
distributions to common shareholders are recorded on the ex-dividend date.
Dividends to preferred shareholders are accrued daily. Dividends from net
investment income and distributions from net realized capital gains are
determined in accordance with federal income tax regulations which may differ
from accounting principles generally accepted in the United States. These
"book/tax" differences are either considered temporary or permanent in nature.
To the extent these differences are permanent in nature, such amounts are
reclassified within the capital accounts based on their federal tax-basis
treatment; temporary differences do not require reclassification.

CONCENTRATION OF RISK

     The Fund follows an investment policy of investing primarily in municipal
obligations of various states. Economic changes affecting those states and
certain of their public bodies and municipalities may affect the ability of the
issuers within those states to pay interest on, or repay principal of, municipal
obligations held by the Fund.

INVESTMENT ADVISOR AND ADMINISTRATOR

     The Board has approved an investment advisory and administration contract
("Advisory Contract") with Brinson Advisors, Inc. ("Brinson Advisors," formerly
known as Mitchell Hutchins Asset Management Inc.), an indirect wholly owned
asset

                                                                              15



NOTES TO FINANCIAL STATEMENTS (CONTINUED)


management subsidiary of UBS AG. UBS AG is an internationally diversified
organization with headquarters in Zurich, Switzerland and operations in many
areas of the financial services industry. In accordance with the Advisory
Contract, Brinson Advisors receives compensation from the Fund, computed weekly
and paid monthly, at the annual rate of 0.90% of the Fund's average weekly net
assets. For the year ended September 30, 2001, Brinson Advisors voluntarily
waived 0.125% of the annual advisory and administration fee, or $307,465 in
investment advisory and administration fees from the Fund.

INVESTMENTS IN SECURITIES

     For federal income tax purposes, the cost of securities owned at September
30, 2001 was substantially the same as the cost of securities for financial
statement purposes.

     At September 30, 2001, the components of net unrealized appreciation of
investments were as follows:

          Gross appreciation (investments having an excess
            of value over cost) ................................... $12,155,630

          Gross depreciation (investments having an excess
            of cost over value) ...................................    (233,636)
                                                                    ------------
          Net unrealized appreciation of investments .............. $11,921,994
                                                                    ============

     For the year ended September 30, 2001, total aggregate purchases and sales
of portfolio securities, excluding short-term securities, were $22,292,927 and
$19,583,790, respectively.

CAPITAL STOCK

     COMMON STOCK--There are 199,998,400 shares of $0.001 par value common stock
authorized and 10,356,667 common shares outstanding at September 30, 2001.

     AUCTION PREFERRED SHARES--The Fund has issued 800 shares of Auction
Preferred Shares Series A and 800 shares of Auction Preferred Shares Series B,
which are referred to herein collectively as the "APS." All shares of each
series of APS have a liquidation preference of $50,000 per share plus an amount
equal to accumulated but unpaid dividends upon liquidation.

     Dividends, which are cumulative, are generally reset every 28 days for APS
Series A and three months for APS Series B. Dividend rates ranged from 2.35% to
6.90% for the year ended September 30, 2001.

     The Fund is subject to certain restrictions relating to the APS. Failure to
comply with these restrictions could preclude the Fund from declaring any
distributions to common shareholders or repurchasing common shares and/or could
trigger the mandatory redemption of APS at liquidation value.

     The APS are entitled to one vote per share and unless otherwise required by
law, will vote with holders of common stock as a single class, except that the
preferred shares will vote separately as a class on certain matters, as required
by law. The holders of the preferred shares have the right to elect two
directors of the Fund.

FEDERAL TAX STATUS

     The Fund intends to distribute substantially all of its tax-exempt income
and any taxable income and to comply with the requirements of the Internal
Revenue Code applicable to regulated investment companies. Accordingly, no
provision for income taxes is required. In addition, by distributing during each
calendar year substantially all of its net investment income, capital gains and
certain other amounts, if any, the Fund intends not to be subject to a federal
excise tax.

INVESTMENT GRADE MUNICIPAL INCOME FUND INC.


REPORT OF INDEPENDENT AUDITORS


To the Board of Directors and Shareholders of
Investment Grade Municipal Income Fund Inc.

We have audited the accompanying statement of assets and liabilities of
Investment Grade Municipal Income Fund Inc. (the "Fund"), including the
portfolio of investments as of September 30, 2001, and the related statements of
operations, changes in net assets and cash flows and the financial highlights
for the year then ended. These financial statements and financial highlights are
the responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audit. The statement of changes in net assets for the year ended September 30,
2000 and the financial highlights for each of the four years in the period ended
September 30, 2000, were audited by other auditors whose report dated November
22, 2000, expressed an unqualified opinion on those statements.

We conducted our audit in accordance with auditing standards generally accepted
in the 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. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements and financial highlights. Our procedures included
confirmation of securities owned at September 30, 2001 by correspondence with
the custodian and brokers. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audit provides a reasonable basis for our opinion.

In our opinion, the 2001 financial statements and financial highlights referred
to above, present fairly, in all material respects, the financial position of
Investment Grade Municipal Income Fund Inc. at September 30, 2001, and the
results of its operations and its cash flows, the changes in its net assets and
the financial highlights for the year then ended, in conformity with accounting
principles generally accepted in the United States.

INVESTMENT GRADE MUNICIPAL INCOME FUND INC.


TAX INFORMATION (UNAUDITED)

     We are required by Subchapter M of the Internal Revenue Code of 1986, as
amended, to advise you within 60 days of the Fund's fiscal year end (September
30, 2001) as to the federal tax status of distributions received by stockholders
during such fiscal year. Accordingly, we are advising you that, with the
exception of a long-term capital gain distribution to common shareholders of
$1,919,090, all dividends paid during the fiscal year were federal tax-exempt
interest dividends.

     The Fund did not invest in any securities which paid interest subject to
the federal alternative minimum tax for individual taxpayers during its fiscal
year. Therefore, none of the dividends paid by the Fund were subject to such
tax.

     Because the Fund's fiscal year is not the calendar year, another
notification will be sent in respect of calendar year 2001. The second
notification, which reflects the amount to be used by calendar year taxpayers on
their federal income tax returns, will be made in conjunction with Form 1099 DIV
and will be mailed in January 2002. Stockholders are advised to consult their
own tax advisors with respect to the tax consequences of their investment in the
Fund.

GENERAL INFORMATION (UNAUDITED)

THE FUND

     Investment Grade Municipal Income Fund Inc. (the "Fund") is a diversified,
closed-end management investment company whose shares trade on the New York
Stock Exchange ("NYSE"). The Fund's investment objective is to achieve a high
level of current income that is exempt from federal income tax, consistent with
the preservation of capital. The Fund's investment advisor and administrator is
Brinson Advisors, Inc., an indirect wholly owned asset management subsidiary of
UBS AG, which had over $76.9 billion in assets under management as of October
31, 2001.

SHAREHOLDER INFORMATION

     The Fund's NYSE trading symbol is "PPM." Comparative net asset value and
market price information about the Fund is published weekly in THE WALL STREET
JOURNAL, THE NEW YORK TIMES and BARRON'S, as well as in numerous other
publications.

DISTRIBUTION POLICY

     The Fund's Board has established a Dividend Reinvestment Plan (the "Plan")
under which all common shareholders whose shares are registered in their own
names, or in the name of UBS PaineWebber or its nominee, will have all dividends
and other distributions on their shares of common stock automatically reinvested
in additional shares of common stock, unless such common shareholders elect to
receive cash. Common shareholders who elect to hold their shares in the name of
another broker or nominee should contact such broker or nominee to determine
whether, or how, they may participate in the Plan. The ability of such
shareholders to participate in the Plan may change if their shares are
transferred into the name of another broker or nominee.

     A shareholder may elect not to participate in the Plan or may terminate
participation in the Plan at any time without penalty, and shareholders who have
previously terminated participation in the Plan may rejoin it at any time.
Changes in elections must be made in writing to the Fund's transfer agent and
should include the shareholder's name and address as they appear on that share
certificate or in the transfer agent's records. An election to terminate
participation in the Plan, until such election is changed, will be deemed an
election by a shareholder to take all subsequent distributions in cash. An
election will be effective only for distributions declared and having a record
date at least ten days after the date on which the election is received.

                                                                              19



INVESTMENT GRADE MUNICIPAL INCOME FUND INC.


GENERAL INFORMATION (UNAUDITED) (CONCLUDED)

     Additional shares of common stock acquired under the Plan will be purchased
in the open market, on the NYSE or otherwise, at prices that may be higher or
lower than the net asset value per share of the common stock at the time of the
purchase. The number of shares of common stock purchased with each dividend will
be equal to the result obtained by dividing the amount of the dividend payable
to a particular stockholder by the average price per share (including applicable
brokerage commissions) that the transfer agent was able to obtain in the open
market. The Fund will not issue any new shares of common stock in connection
with the Plan. There currently is no charge to participants for reinvesting
dividends or other distributions. The transfer agent's fees for handling the
reinvestment of distributions will be paid by the Fund. However, each
participant pays a pro rata share of brokerage commissions incurred with respect
to the transfer agent's open market purchases of common stock in connection with
the reinvestment of distributions. The automatic reinvestment of dividends and
other distributions in shares of common stock does not relieve participants of
any income tax that may be payable on such distributions.

     Experience under the Plan may indicate that changes are desirable.
Accordingly, the Fund reserves the right to amend or terminate the Plan with
respect to any dividend or other distribution if notice of the change is sent to
Plan participants at least 30 days before the record date for such distribution.
The Plan may also be amended or terminated by the transfer agent by at least 30
days' written notice to all plan participants. Additional information regarding
the Plan may be obtained from, and all correspondence concerning the Plan should
be directed to, the transfer agent at PFPC Inc., P.O. Box 8030, Boston,
Massachusetts 02266. For further information regarding the Plan, you may also
contact the transfer agent directly at 1-800-331-1710.
