DEAN WITTER INTERCAPITAL CALIFORNIA INSURED MUNICIPAL INCOME TRUST
Two World Trade Center
New York, New York 10048
DEAR SHAREHOLDER:
- - --------------------------------------------------------------------------------
When InterCapital California Insured Municipal Income Trust (NYSE symbol:
IIC) began its new fiscal year in November 1993, municipal yields had reached
record lows in a trend that began six years ago. Strong economic growth in the
fourth quarter of 1993 prompted concern about inflation and caused interest
rates to rise. The Federal Reserve Board tightened monetary policy by raising
the federal-funds rate -- the interest rate that banks charge each other for
overnight loans -- from 3.00 percent to 3.75 percent in three separate moves
between early February and April. This action was presented as a preemptive
strike against inflation. However, the fixed-income markets interpreted the
change in Fed policy as the beginning of a trend toward higher interest rates.
In mid-May, the Federal Reserve Board initiated another round of tightening with
a 50 basis point increase in both the federal-funds rate and the discount rate
- - -- the interest rate the Federal Reserve charges member banks for loans.
By the end of April the bond market was battered. Interest rates were at
levels not seen in over a year. Long-term municipal bond yields as measured by
THE BOND BUYER Revenue Bond Index* increased by 86 basis points from 5.56
percent to 6.42 percent between November and April. This corresponded to a price
decline of more than 11 percent.
New-issue underwriting totaled $290 billion in 1993, a 23 percent increase
over the previous high of $235 billion set in 1992. Refunding issues, which are
used by state and local governments to refinance higher-coupon debt, represented
66 percent of total volume last year. It is estimated that 1994's underwriting
volume will decline by 30 percent to about $200 billion and that approximately
$260 billion in bonds will either mature or be called. Thus, the amount of
municipal debt outstanding will be reduced. In line with these projections,
new-issue volume for the first four months of 1994 declined by 34 percent and
totaled $59 billion. Refunding activity, the catalyst of last year's record
underwriting, dropped even more sharply.
PERFORMANCE
For the six-month period ended April 30, 1994, the Trust paid shareholders
tax-free income dividends totaling $0.435 per share, including a short-term
capital gains distribution of $0.005 per share distributed in December. IIC's
total return for this period was - 8.70 percent. This calculation is based on a
change in the Trust's New York Stock Exchange market price from $15.375 on
October 31, 1993 to $13.625 per share on April 30, 1994 and includes the
reinvestment of all dividends and distributions. Over the same period, the
Trust's net asset value (NAV) declined about 16 percent from $14.87 to $12.45
per share. The current-coupon bonds purchased by the Trust in 1993 declined in
line with the Revenue Bond Index. However, the preferred stock leverage (as
discussed below) caused the Trust's NAV to decline 1.4 times more than the
unleveraged Revenue Bond Index. As of April 30, 1994, the Trust was trading at a
9.44 percent premium to NAV.
- - ------------
* THE BOND BUYER Revenue Bond Index is an arithmetic average of the yields of 25
selected municipal revenue bonds with 30-year maturities. Ratings of these
bonds range from Aaa to Baa 1 by Moody's and AAA to A-by S&P.
<PAGE>
PORTFOLIO STRUCTURE
The portfolio's long-term investments were diversified among seven specific
municipal sectors and 43 credits. The three largest sectors were water and
sewer, tax allocation and electric revenue bonds, representing 53 percent of net
assets. The average maturity and call protection of the Trust's long-term
holdings were 25 years and 9 years, respectively. At the end of the period, the
Trust's net assets exceeded $275 million.
Each position in the portfolio was backed either by bond insurers that are
rated Aaa by Moody's Investors Service, Inc. and AAA by Standard & Poor's Corp.
This is to ensure the timely payment of principal and interest. The distribution
of long-term credit enhancements was:

Financial Security Assurance Inc. (FSA)....................................................... 5.2
Municipal Bond Investors Assurance Corporation (MBIA)......................................... 50.3
</TABLE>
PREFERRED SHARE LEVERAGE
In addition to common shares, the Trust has also issued four $25 million
series of Auction Rate Preferred Shares (ARPS). Dividend and distribution
payments for these shares rank ahead of the common shares. ARPS are short-term
securities with maturities normally ranging from one week to one year. The
dividend rates on tax-free ARPS are established by an auction process when the
maturity is rolled over. The Trust uses the proceeds from ARPS issuance to
purchase long-term municipal bonds.
The common shares are impacted by the preferred shares in two ways. First,
following the payment of the dividend on the ARPS, common shares receive any
extra incremental income when the long-term portfolio yield is higher than the
cost of the ARPS (yield plus expenses). Second, the preferred shares leverage
the common shares by a factor of approximately 1.5 times, thus multiplying any
market change in NAV. Over the past six months, incremental tax-free income from
the ARPS leverage maintained common share dividends and increased the level or
cushion of undistributed net investment income. As of April 30, 1994, an amount
equivalent to $0.085 per share had been accumulated in this cushion to help
sustain the Trust's current dividend. The average ARPS rate on the Trust's four
outstanding series as of April 30, 1994 was 2.76 percent, with all resets
scheduled to occur within 5 months. Higher yields in future ARPS auctions may
begin to erode the Trust's cushion of undistributed net investment income
available for distribution to common shareholders. If the cushion were to erode
significantly over time, the Trust would take appropriate action which could
include an adjustment in the common dividend and/ or a reduction in the amount
of ARPS.
Leverage was a positive influence on the overall value of the portfolio for
the first year of the Trust's existence. However, the increase in interest rates
over the past few months has adversely impacted NAV.
LOOKING AHEAD
A continuation of low new-issue supply, coupled with significant bond calls
and maturities should sustain investor demand for municipals. However, the
overall direction of interest rates will primarily be determined by the strength
of the economy, the trend of inflation and the Federal Reserve Board's response
to economic conditions.
The Trust's procedure for reinvestment of all dividends and distributions on
common shares is by purchase in the open market. This method helps to support
the market value of the Trust's shares. In addition, the Trustees have approved
a procedure whereby the Trust may attempt to reduce or eliminate
<PAGE>
a market value discount from net asset value by repurchasing common shares in
the open market or in privately negotiated transactions. The Trust may also
utilize procedures to reduce or eliminate the amount of outstanding ARPS,
including their repurchase in the open market or in privately negotiated
transactions.
We appreciate your support of InterCapital California Insured Income Trust
and look forward to continuing to serve your investment needs.
Very truly yours,
Charles A. Fiumefreddo
CHAIRMAN OF THE BOARD

INTERCAPITAL CALIFORNIA INSURED MUNICIPAL INCOME TRUST
NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

1. ORGANIZATION AND ACCOUNTING POLICIES -- InterCapital California Insured
Municipal Income Trust (the "Trust") is registered under the Investment Company
Act of 1940, as amended, as a non-diversified closed-end management investment
company. It was organized on November 2, 1992 as a Massachusetts business trust
and had no operations until February 26, 1993 other than matters related to the
sale and issuance of 7,113 common shares of beneficial interest to Dean Witter
InterCapital Inc. (the "Investment Manager").
The following is a summary of significant accounting policies:
A. VALUATION OF INVESTMENTS -- Portfolio securities are valued for the
Trust by an outside independent pricing service approved by the Trustees.
The pricing service has informed the Trust that in valuing the Trust's
portfolio securities, it uses both a computerized grid matrix of tax-exempt
securities and evaluations by its staff, in each case based on information
concerning market transactions and quotations from dealers which reflect the
bid side of the market each day. The Trust's portfolio securities are thus
valued by reference to a combination of transactions and quotations for the
same or other securities believed to be comparable in quality, coupon,
maturity, type of issue, call provisions, trading characteristics and other
features deemed to be relevant.
B. ACCOUNTING FOR INVESTMENTS -- Security transactions are accounted for on
the trade date (date the order to buy or sell is executed). In computing net
investment income, the Trust amortizes premiums and original issue discounts
on fixed income securities. Additionally, with respect to market discount on
bonds purchased after April 30, 1993, a portion of any capital gain realized
upon disposition is recharacterized as taxable investment income. Realized
gains and losses on security transactions are determined on the identified
cost method. Interest income is accrued daily.
C. FEDERAL INCOME TAX STATUS -- It is the Trust's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute all of its taxable and nontaxable income to its
shareholders. Accordingly, no federal income tax provision is required.
D. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- The Trust records
dividends and distributions to its shareholders on the ex-dividend date. The
amount of dividends and distributions from net investment income and net
realized capital gains 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 reclassifications.
Dividends and distributions which exceed net investment income and net
realized capital gains for financial reporting purposes but not for tax
purposes are reported as dividends in excess of net investment income or
distributions in excess of net realized capital gains. To the extent they
exceed net investment income and net realized capital gains for tax
purposes, they are reported as distributions of paid-in-capital.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)
- - --------------------------------------------------------------------------------
E. ORGANIZATIONAL AND OFFERING EXPENSES -- The Trust's Investment Manager
paid the organizational and offering expenses of the Trust's common shares
in the amount of $36,000 and $395,438, respectively, and paid $293,608 in
offering expenses of the Trust's preferred shares. Organizational expenses
have been reimbursed by the Trust for the full amount thereof which have
been deferred and are being amortized by the straight-line method over a
period not to exceed five years from the commencement of operations.
Offering expenses have been reimbursed by the Trust and were charged to
capital at the time of issuance of the Trust's respective shares.
2. INVESTMENT MANAGEMENT AGREEMENT -- Pursuant to an Investment Management
Agreement (the "Agreement") with Dean Witter InterCapital Inc., the Trust pays
its Investment Manager a management fee, calculated weekly and payable monthly,
by applying the annual rate of 0.35% to the Trust's average weekly net assets.
Under the terms of the Agreement, in addition to managing the Trust's
