INVESTMENT GRADE MUNICIPAL INCOME FUND INC. SEMIANNUAL REPORT
May 20, 1999
Dear Shareholder,
We are pleased to present you with the semiannual report for the Investment
Grade Municipal Income Fund Inc. (the "Fund") for the six-month period ended
March 31, 1999.
MARKET REVIEW
- --------------------------------------------------------------------------------
[GRAPHIC OMITTED]
The crisis in Russia last August and fears of it spreading to Latin America
heightened investors' aversion to credit risk and prompted them to sell other
securities in favor of U.S. Treasurys. The "flight to quality" ultimately drove
U.S. Treasury bond yields to a low of 4.70% in October. To fend off a
threatening global financial crisis, the Federal Reserve cut the short-term
interest rate by 0.25% three times in as many months, lowering it from 5.50% to
4.75%. As the bond markets began to stabilize, investors returned to them in
search of bargains.
Long-term interest rates remained in the low 5% range until early February
1999, when Federal Reserve Chairman Alan Greenspan expressed an inclination to
restrain economic policy and confessed that he might have overdone interest-rate
cuts during the fall crisis. This surprised market participants, and the yield
on the 30-year Treasury bond rose by about one-half of a percentage point in
response. Economic growth and inflation held steady, however, so investors had
no real cause for concern.
As Treasury yields rose in February, municipal bonds strongly outperformed
taxable bonds, reversing their underperformance throughout 1998. Long-term
AAA-rated municipal bonds finished the fiscal year yielding about 84% of
comparable U.S. Treasurys--close to their historical average. At year-end 1998,
municipal bonds yielded about 97% of U.S. Treasurys. As rates rose,
municipalities delayed their financing, further decreasing supply and resulting
in significant municipal bond outperformance.
PORTFOLIO REVIEW
- --------------------------------------------------------------------------------
[GRAPHIC OMITTED]
Performance--For the six-month period ended March 31, 1999, the Fund (symbol:
PPM) returned 1.36% based on changes in the Fund's net asset value (assuming,
for illustration only, that dividends were reinvested at the net asset value on
the payable dates) and 2.46% based on changes in its share price on the New York
Stock Exchange (assuming dividends were reinvested under the Dividend
Reinvestment Plan).
At March 31, 1999, the Fund's net asset value per share was $16.87, while its
share price on the New York Stock Exchange was $15.88. During the six-month
period ended March 31, 1999, the Fund paid dividends to common stockholders from
net investment income totaling $0.45 per share, or $0.075 per share per month.
Based on the dividend paid in March and the Fund's market price on March 31,
1999, the Fund's annualized market yield was 5.67%.
Highlights--During the period we sold some pre-refunded holdings and replaced
them with longer-maturity securities to maintain our duration (interest-rate
exposure) targets. Portfolio additions during the period included Massachusetts
Water (0.8%), Philadelphia School District (1.1%) and New York City (0.6%).*
Each bond purchased represents an attractive structure that provides convexity,
that is, greater potential for total return, and above average-yield for its
duration risk.
* Weightings represent percentages of portfolio assets as of March 31, 1999. The
Fund's portfolio is actively managed and its composition will vary over time.

OUTLOOK
- --------------------------------------------------------------------------------
[GRAPHIC OMITTED]
Concerns about the domestic economy and inflation have reemerged recently.
Though we continue to look for swap opportunities to achieve our duration
targets, we have become more cautious and expect to target a more moderate level
of interest rate risk than we would have six months ago. Municipal issuance was
moderate during the last reporting period. We do not expect it to change
dramatically in the next period, and believe that municipal bonds will stay
within their current trading range in relation to taxable bonds.
Our ultimate objective in managing your investments is to help you
successfully meet your financial goals. We thank you for your continued support
and welcome any comments or questions you may have. For a Quarterly Review on

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 preparation of financial statements in accordance with generally accepted
accounting principles 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--Where market quotations are readily available,
portfolio securities are valued thereon, provided such quotations adequately
reflect the fair value of the securities, in the judgment of Mitchell Hutchins
Asset Management Inc. ("Mitchell Hutchins"), a wholly owned asset management
subsidiary of PaineWebber Incorporated and investment adviser and administrator
of the Fund. When market quotations are not readily available, securities are
valued based upon appraisals received from a pricing service which utilizes a
computerized matrix pricing system, or based upon appraisals derived from
information concerning those securities or similar securities received from
recognized dealers in those securities. All other securities are valued at fair
value as determined in good faith by or under the direction of the Fund's board
of directors. The amortized cost method of valuation, which approximates market
value, is used to value certain debt obligations with 60 days or less remaining
to maturity, unless the Fund's board of directors 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 securities.
Dividends and Distributions--The Fund intends to pay monthly dividends to
common stockholders 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 stockholders are recorded on the ex-dividend date.
Dividends to preferred stockholders are accrued daily. Dividends from net
investment income and distributions from realized capital gains from investment
transactions are determined in accordance with federal income tax regulations
which may differ from generally accepted accounting principles.
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 ADVISER AND ADMINISTRATOR
The Fund's board of directors has approved an investment advisory and
administration contract ("Advisory Contract") with Mitchell Hutchins, under
which Mitchell Hutchins serves as investment adviser and administrator of the
Fund. In accordance with the Advisory Contract, Mitchell Hutchins 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 six months ended March
31, 1999, Mitchell Hutchins voluntarily waived $159,613 in investment advisory
and administration fees from the Fund.

INVESTMENTS IN SECURITIES
For federal income tax purposes, the cost of securities owned at March 31,
1999 was substantially the same as the cost of securities for financial
statement purposes.
At March 31,1999, the components of the net unrealized appreciation of
investments were as follows:
<TABLE>
<S> <C>
Gross appreciation (from investments having an excess of value over cost).............. $19,883,648
Gross depreciation (from investments having an excess of cost over value).............. (75,902)
-----------
Net unrealized appreciation of investments............................................. $19,807,746
===========
</TABLE>
For the six months ended March 31, 1999, total aggregate purchases and sales
of portfolio securities, excluding short-term securities, were $6,453,925 and
$7,692,525, respectively.
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.
At September 30, 1998, the Fund had a net capital loss carryforward of
$343,878 available as a reduction, to the extent provided in the regulations, of
future net realized capital gains, and will expire by September 30, 2004. To the
extent that such losses are used to offset future capital gains, it is probable
that the gains so offset will not be distributed.
CAPITAL STOCK
Common Stock--There are 199,998,400 shares of $0.001 par value common stock
authorized. Of the 10,356,667 common shares outstanding, 8,235 shares are owned
by Mitchell Hutchins.
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 3 months for APS Series B. Dividend rates ranged from 3.00% to
3.55% for the six months ended March 31, 1999.
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.

YEAR 2000 RISKS
Like other funds and financial and business organizations around the world,
the Fund could be adversely affected if the computer systems used by its
investment adviser, other service providers and entities with computer systems
that are linked to Fund records do not properly process and calculate
date-related information and data from and after January 1, 2000. This is
commonly known as the "Year 2000 Issue."
Mitchell Hutchins is taking steps that it believes are reasonably designed to
address the Year 2000 Issue with respect to the computer systems that it uses,
and to obtain satisfactory assurances that each of the Fund's other major
service providers is taking comparable steps. However, there can be no assurance
that these steps will be sufficient to avoid any
adverse impact on the Fund.
DISTRIBUTION POLICY
The Fund's Board of Directors has established a Dividend Reinvestment Plan
(the "Plan") under which all common stockholders whose shares are registered in
their own names, or in the name of 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 stockholders
elect to receive cash. Common stockholders 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
stockholders to participate in the Plan may change if their shares are
transferred into the name of another broker or nominee.
A stockholder may elect not to participate in the Plan or may terminate
participation in the Plan at any time without penalty, and stockholders 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 stockholder'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 stockholder to take all subsequent distributions in cash. An
election will
16
<PAGE>
INVESTMENT GRADE MUNICIPAL INCOME FUND INC.
GENERAL INFORMATION (concluded)
be effective only for distributions declared and having a record date at least
ten days after the date on which the election is received.
Additional shares of common stock acquired under the Plan will be purchased
in the open market, on the NYSE, 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 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.
Additional information regarding the Plan may be obtained from, and all
correspondence concerning the Plan should be directed to, the transfer agent at
PNC Bank, National Association, c/o PFPC Inc., P.O. Box 8950, Wilmington,
Delaware 19899.
