INSURED MUNICIPAL INCOME FUND INC. SEMIANNUAL REPORT
November 14, 1997
Dear Shareholder,
We are pleased to present the semiannual report for Insured Municipal
Income Fund Inc. for the six months ended September 30, 1997.
GENERAL MARKET OVERVIEW
================================================================================
[GRAPHIC OMITTED] The Federal Reserve's decision to raise short-term interest
rates in March contributed to negative returns in virtually every bond sector
for the first quarter of 1997. Good news, however, came on April 28, when the
report of the Employment Cost Index--considered the most comprehensive
wage-inflation indicator, and critical to Fed policy--presented a very positive
inflation picture. This information, combined with other factors, turned market
sentiment extremely bullish. Bonds entered a prolonged rally that, supported
by additional favorable data, continued through July and into the beginning of
August. Municipal bonds generally outperformed during this rally, as new issue
supply withered and demand increased from the June/July rollover of maturing
municipal bonds. September ended the fiscal period on a positive note, as the
prevailing theme in the market was that above-trend economic growth could occur
without generating higher inflation. The final result: the yield on the 30-year
Treasury bond declined by almost 40 basis points from where it had been three
months prior, which coincided with a compression of municipal credit spreads.
PORTFOLIO REVIEW
================================================================================
[GRAPHIC OMITTED] PERFORMANCE--The Fund's total return for the six months ended
September 30, 1997, based on the Fund's common stock net asset value was
9.76%, while the Fund's total return for the same time period based on the
Fund's market value was 14.80%. As of September 30, 1997, the Fund's net
asset value per share was $15.08, and its share price on the New York Stock
Exchange was $13.38.
The Fund paid dividends from net investment income to common shareholders,
which totaled $0.38 per share of common stock during the six months ended
September 30, 1997. The Fund has paid a monthly dividend of $0.064 per
share of common stock since July 1995. Given the current interest rate
environment, we anticipate that the monthly dividend will remain unchanged
for the remainder of 1997.
During the fiscal period, the Fund easily outperformed the 7.57% return of
its Lipper

PORTFOLIO HIGHLIGHTS--The low interest rate environment that existed
throughout the semiannual period was extremely conducive to the Fund's long
duration portfolio, and contributed greatly to its strong showing over the
period.
OUTLOOK
================================================================================
[GRAPHIC OMITTED] Near term, we foresee continued above-trend economic
growth. We anticipate that long rates will remain stable and, therefore, we
will maintain a neutral duration strategy. Finally, we will continue to
diversify across the maturity curve to dampen share price volatility.
Relative to other taxable securities, we believe that municipal bonds will
remain attractive. Given the municipal markets' correlation to technical factors
such as supply and demand, we will continue to take advantage of inefficiencies
as they arise. As always, we will monitor the municipal environment on a
state-by-state basis, as well as the relative value relationships between
municipal sectors. Additionally, we will seek municipal bonds that provide more
upside potential with relatively less downside risk.
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.
Sincerely,
/s/MARGO N. ALEXANDER /s/ELBRIDGE T. GERRY III /s/RICHARD S. MURPHY

ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
Insured Municipal Income Fund Inc. (the "Fund" ) was incorporated in
Maryland on February 18, 1993, and is registered with the Securities and
Exchange Commission as a closed-end diversified management investment company.
Organizational costs have been deferred and are being amortized on the
straight-line method over a period not to exceed 60 months from the date the
Fund commenced operations.
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, 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 cash
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. 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 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
13

NOTES TO FINANCIAL STATEMENTS (unaudited)
monthly, at the annual rate of 0.90% of the Fund's average weekly net
assets. For the six months ended September 30, 1997, Mitchell Hutchins
voluntarily waived $471,374 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, 1997 was substantially the same as the cost of securities for financial
statement purposes.
At September 30, 1997, the components of the net unrealized appreciation of
investments were as follows:
<TABLE>
<CAPTION>
<S> <C>
Gross appreciation (from investments having an excess of value over cost) ........................ $22,365,676
Gross depreciation (from investments having an excess of cost over value) ........................ --
-----------
Net unrealized appreciation of investments ....................................................... $22,365,676
===========
</TABLE>
FEDERAL TAX STATUS
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 federal 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 March 31, 1997, the Fund had a net capital loss carryforward of
$14,804,597 which is available as a reduction, to the extent provided in the
regulations, of future net realized capital gains and will expire by March 31,
2003. 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 199,997,000 shares of $0.001 par value common
stock authorized. Of the 20,628,363 common shares outstanding, 15,366 shares are
owned by Mitchell Hutchins.
AUCTION PREFERRED SHARES -- The Fund has issued 800 shares of Auction
Preferred Shares, Series A, 800 shares of Auction Preferred Shares, Series B,
800 shares of Auction Preferred Shares, Series C and 600 shares of Auction
Preferred Shares, Series D 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 7 days for APS
Series A and D, 28 days for APS Series B and three months for APS Series C.
Dividend rates ranged from 3.30% to 4.10% for the six months ended September 30,
1997. Effective January 6, 1997, Series A reset to a special dividend period of
364 days.
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.

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 Incorporated or its nominee, 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.
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 Fund
will not issue any new shares of common stock in connection with the Plan.
