Dear Shareholder,

We present you with the semiannual report for Investment Grade Municipal Income
Fund Inc. for the six months ended March 31, 2002.

Q. HOW DID THE FUND PERFORM DURING THE PERIOD RELATIVE TO ITS PEERS?

A. For the six months ended March 31, 2002, the Fund's net asset value grew
   0.5% and its market price increased 0.6%, outperforming its competitors,
   measured by the Lipper General Municipal Debt Fund (Leveraged) Median. The
   Lipper Median's net asset value declined 0.7% and its market price advanced
   0.4%. The Fund's relatively short average duration compared to its peers
   was the primary factor that helped it to outperform its benchmark.

Q. WHAT ECONOMIC FACTORS AFFECTED FUND PERFORMANCE?

A. The Federal Reserve's (The "Fed") unprecedented 11 fed funds rate cuts
   totaling 4.75% in 2001 depressed bond yields during the period. Optimism
   was the watchword at the start of 2002 as a series of positive economic
   indicators pointed toward a sustained economic recovery. The business
   activity index released in February by the Institute for Supply Management
   (ISM), a group of purchasing managers, rose above 50-signifying expansion
   for the first time in 18 months. Since then, the ISM index has posted
   scores of 55.6 in March and 53.9 post-period in April.

   The nation's economic output also grew rapidly during the first quarter at
   a rate of 5.8%, after a growth rate of 1.7% in the fourth quarter of 2001
   and a contraction of 1.3% in the third quarter of 2001 during the depth of
   the recession. During this time, the Fed adopted a neutral bias from its
   former easing stance.

   However, unemployment remained stubbornly high, climbing to 6.0%
   post-period after reaching 5.7% in March. Additionally, the equity markets
   struggled again after a brief rally at the beginning of the year. A spate
   of companies questioned about their accounting and reporting practices did
   little to ease investors' fears.

*    Effective April 8, 2002, Brinson Advisors, Inc. was renamed UBS Global
     Asset Management (US) Inc. Mr. Veronda assumed management responsibility of
     the Fund effective May 20, 2002.


Q.   WHAT MARKET FACTORS AFFECTED THE INVESTMENT GRADE MUNICIPAL FUND DURING THE
     PERIOD?

A.   Undoubtedly, The Fed's easing had the greatest effect on performance.
     However, the municipal market outperformed the taxable fixed income market
     despite a glut of new supply issued during the first quarter of 2002. The
     Fed's change from an easing to a neutral bias in March 2002 also helped to
     flatten the Treasury yield curve late in the period. At its peak in
     September, the yield curve was 269 points-the steepest curve since 1993.
     Since then, the yield curve has fallen to 235 points in March 2002.


Q.   WHICH STRATEGIES HELPED OR HINDERED FUND PERFORMANCE DURING
     THE PERIOD?


A.   The best performing point on the short end of the curve was at five years,
     with issues in this maturity range also quickly giving us the leverage to
     reposition when opportunities presented themselves. As a result, the
     weighted-average duration for the Fund was 4.80 years, although we have
     been increasing duration since late in the reporting period as the yield
     curve has flattened. We have combined our focus on the short end with a
     focus on the 15-year range, giving the portfolio a barbell-shaped
     structure. This strategy has allowed us to capture favorable returns at
     both ends of the spectrum.

Security selection also helped performance during the period. The September 11
terrorist attacks knocked out bond broking giant Cantor Fitzgerald, which
virtually halted liquidity. In the succeeding weeks, travel industry sectors
such as airlines, airports and hotels were severely affected. We were
underweighted in these sectors during this time.

Investment Grade Municipal Income Fund Inc.

Q. TO ILLUSTRATE YOUR INVESTMENT STRATEGIES, PLEASE PROVIDE DETAILS FOR TWO OR
   THREE HOLDINGS THAT YOU BOUGHT OR SOLD DURING THIS REPORTING PERIOD?

A. Buy and sell activity was slow during the period, as we attempted to
   forestall capital gains where we could. We did buy $2.825 million in bonds
   from Fort Worth (Texas) Water and Sewer at 5.625% (matures in 2016). We
   also bought $3.305 million in Indiana Transportation Finance Authority
   bonds due November 2012, as well as a 30-year, $2.250 non-callable bond
   from the Massachusetts State Health and Education Facility Financing
   Authority. Both bonds had a 5.5% coupon.*

Q. LASTLY, WHAT IS YOUR SHORT-TERM AND LONG-TERM OUTLOOK FOR THE MARKET?

A. We anticipate staying relatively short to our benchmark and peers on average
   duration, while we will continue to employ a barbell strategy. With good
   value at the 12- to 17-year range of the yield curve, we will also look for
   opportunities in this area.

   We will continue to stress the more premium-structured defensive bonds, as
   worries about credit quality will continue throughout the year. During the
   period, we were overweighted in the essential revenue, general obligation
   and education sectors. In the coming months, we will continue our
   overweight in at least two of these three sectors-essential revenue and
   education. We will monitor the general obligation area, where we anticipate
   weaker credit quality as states, such as California, and even cities, such
   as New York, see their credit ratings downgraded. We anticipate debt from
   North Carolina and Georgia to remain quality opportunities.







*     Weightings represent percentages of net assets as of the dates indicated.
      As of March 31, 2002, Fort Worth (Texas) Water and Sewer, Indiana
      Transportation Finance Authority and Massachusetts State Health and
      Education Facility Financing Authority represented 1.8%, 4.2% and 1.4% of
      net assets, respectively. The Fund's portfolio is actively managed and
      its composition will vary over time.

     Inception returns for Lipper Median are shown as of nearest month-end of
     the Fund's inception: October 31, 1992. Past performance is no guarantee of
     future results. The Fund's share price and investment return will vary so
     that an investor's shares may be worth more or less than their original
     cost. NAV and market price returns for periods of less than one year are
     not annualized. NAV return assumes, for illustration only, that dividends
     were reinvested at the net asset value on the ex-dividend dates.

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


     Market yield is calculated by multiplying the March dividend by 12 and
     dividing by the month-end market price. NAV yield is calculated by
     multiplying the month-end dividend by 12 and dividing by the month-end net
     asset value. IPO yield is calculated by multiplying the month-end dividend
     by 12 and dividing by the initial public offering price. Prices and yields
     will vary.

Notes to Financial Statements (unaudited)

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 under the Investment Company Act of 1940, as amended, 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. 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 shares. Dividends and distributions to
common shareholders are recorded on the ex-dividend date. Dividends to
preferred shareholders are accrued daily. The amount of dividends from net
investment income and distributions from net realized capital gains is
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


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

        Investment Grade Municipal Income Fund Inc.

        Notes to Financial Statements (unaudited) (continued)

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.


CHANGE IN ACCOUNTING PRINCIPLE

In July 2001, a Securities and Exchange Commission staff announcement, Emerging
Issues Task Force Discussion ("EITF D")-98, Classification and Measurement of
Redeemable Securities, was issued providing new guidance related to the
presentation of preferred shares in financial statements. EITF D-98 is required
to be applied beginning with fiscal quarters ending after December 15, 2001 on
a retroactive basis, by restating the prior year's financial statements. In
accordance with the announcement, the Fund has presented its auction preferred
shares outside of net assets and has presented dividends to preferred
shareholders on such auction preferred shares in the net change in net assets
attributable to common shareholders resulting from operations for all periods
presented. Therefore, beginning net assets attributable to common shareholders
have been restated and dividend activity related to preferred shares has been
reclassified from the capital activity in the statements of changes in net
assets and the financial highlights to the operating activity. The application
of EITF D-98 related entirely to presentation and had no impact on net asset
value or the allocation of net income or capital gains or losses to common
shareholders.


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 UBS Global Asset Management (US) Inc. ("UBS Global
AM", formerly known as Brinson Advisors, Inc.), under which UBS Global AM
serves as investment advisor and administrator of the Fund. In accordance with
the Advisory Contract, the Fund pays UBS Global AM an investment advisory and
administration fee, which is accrued weekly and paid monthly, at the annual
rate of 0.90% of the Fund's average weekly net assets. For the six months ended
March 31, 2002, UBS Global AM voluntarily waived $153,310 in investment
advisory and administration fees from the Fund.

Notes to Financial Statements (unaudited) (concluded)

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 90 days for APS Series B. Dividend rates ranged from 1.278% to
2.300% for the six months ended March 31, 2002.

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
For federal income tax purposes, the cost of securities owned at March 31, 2002
was substantially the same as the cost of securities for financial statement
purposes.

were as follows:



                                                                          
Gross appreciation (investments having an excess of value over cost) .....   $7,827,236
Gross depreciation (investments having an excess of cost over value) .....   (1,517,873)
                                                                             ----------
Net unrealized appreciation of investments. ..............................   $6,309,363
                                                                             ==========


For the six months ended March 31, 2002, total aggregate purchases and sales of
portfolio securities, excluding short-term securities, were $33,933,240 and

The Fund intends to distribute substantially all of its tax-exempt income and
any taxable income and to comply with the other 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.

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
UBS Global Asset Management (US) Inc. ("UBS Global AM"), an indirect wholly
owned asset management subsidiary of UBS AG, which had over $75.6 billion in
assets under management as of April 30, 2002.

Effective May 20, 2002, William Veronda assumed primary responsibility for the
day-to-day management of the Fund. Mr. Veronda is an Executive Director and
portfolio manager of UBS Global AM. Mr. Veronda joined UBS Global AM in
September 1995 and has led its municipal research group since that date. Mr.
Veronda previously served as the portfolio manager for PaineWebber Municipal
High Income Fund from September 1995 until March 2001.


INVESTMENT POLICY CHANGES

The Fund's board approved modifications to the Fund's investment policies as a
result of a new rule promulgated by the Securities and Exchange Commission.
This rule generally requires a fund with a name suggesting that it focuses on a
particular type of investment to invest at least 80% of its net assets (plus
the amount of any borrowing for investment purposes) in the type of investment
suggested by its name. The investment policy changes became effective on April
8, 2002. These changes are not expected to affect materially portfolio
management.

The new 80% policy has been adopted as a "fundamental" investment policy; the
Fund may not deviate from this 80% policy without shareholder approval. Many of
the Fund's other investment policies are non-fundamental policies and may be
changed by its board without shareholder approval. The Fund will interpret
these new policies as if the following phrase appeared immediately after the
words "net assets": "(plus the amount of any borrowing for investment
purposes)." If subsequent to an investment, the Fund's 80% policy is no longer
met (e.g., bonds are called resulting in a large influx of cash), then under
normal circumstances, the Fund's future investments would be made in a manner
that would bring the Fund's investments back in line with the 80% threshold.

In order to place these changes in context, reproduced below are prior policies
that were impacted by this change as well as new policies which replace the
prior policies:

General Information (unaudited) (continued)


INVESTMENT POLICY CHANGES (CONCLUDED)

Prior Policies Impacted by Change

The Fund normally invests substantially all of its assets in a diversified
portfolio of long-term, tax-exempt Municipal Obligations that have been rated
investment grade or are unrated but have been determined to be of comparable
quality by UBS Global AM. Municipal Obligations rated investment grade are
those that, at the time of investment, are rated within the four highest grades
by Moody's (Baa or higher) or S&P (BBB or higher) or have an equivalent rating
from another nationally recognized statistical rating organization. The Fund
may invest up to 20% of its total assets in Municipal Obligations that are
unrated but that, at the time of investment, have been determined by UBS Global
AM to be of comparable quality to those that are rated investment grade. Under
normal circumstances, the Fund invests at least 65% of its total assets in
income-producing securities.


Revised Policies

The Fund normally invests substantially all of its assets in a diversified
portfolio of long-term Municipal Obligations. Under normal circumstances, the
Fund invests at least 80% of its net assets in investment grade Municipal
Obligations, the income from which is exempt from regular federal income tax.
Municipal Obligations rated investment grade are those that, at the time of
investment, are rated within the four highest grades by Moody's (Baa or higher)
or S&P (BBB or higher) or have an equivalent rating from another nationally
recognized statistical rating organization. The Fund may invest up to 20% of
its net assets in Municipal Obligations that are unrated but that, at the time
of investment, have been determined by UBS Global AM to be of comparable
quality to those that are rated investment grade.


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.

An annual meeting of shareholders of the Fund was held on January 17, 2002. At
the meeting, Margo N . Alexander, Richard Q. Armstrong, David J. Beaubien, E.
Garrett Bewkes, Jr., Richard R. Burt, Meyer Feldberg, George W. Gowen, William

DIVIDEND REINVESTMENT PLAN

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 Inc. 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 common shareholder may elect not to participate in the Plan or may terminate
participation in the Plan at any time without penalty, and common 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 common 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.

General Information (unaudited) (concluded)


DIVIDEND REINVESTMENT PLAN (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 shareholder 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 also may 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 02266-8030. For further information regarding the Plan, you may
also contact the transfer agent directly at 1-800-381-1710.
