The Benefits and
Risks of
Leveraging

MuniHoldings California Insured Fund, Inc. utilizes leverage to seek to enhance
the yield and net asset value of its Common Stock. However, these objectives
cannot be achieved in all interest rate environments. To leverage, the Fund
issues Preferred Stock, which pays dividends at prevailing short-term interest
rates, and invests the proceeds in long-term municipal bonds. The interest
earned on these investments is paid to Common Stock shareholders in the form of
dividends, and the value of these portfolio holdings is reflected in the per
share net asset value of the Fund's Common Stock. However, in order to benefit
Common Stock shareholders, the yield curve must be positively sloped; that is,
short-term interest rates must be lower than long-term interest rates. At the
same time, a period of generally declining interest rates will benefit Common
Stock shareholders. If either of these conditions change, then the risks of
leveraging will begin to outweigh the benefits.

To illustrate these concepts, assume a fund's Common Stock capitalization of
$100 million and the issuance of Preferred Stock for an additional $50 million,
creating a total value of $150 million available for investment in long-term
municipal bonds. If prevailing short-term interest rates are approximately 3%
and long-term interest rates are approximately 6%, the yield curve has a
strongly positive slope. The fund pays dividends on the $50 million of Preferred
Stock based on the lower short-term interest rates. At the same time, the fund's
total portfolio of $150 million earns the income based on long-term interest
rates. Of course, increases in short-term interest rates would reduce (and even
eliminate) the dividends on the Common Stock.

In this case, the dividends paid to Preferred Stock shareholders are
significantly lower than the income earned on the fund's long-term investments,
and therefore the Common Stock shareholders are the beneficiaries of the
incremental yield. However, if short-term interest rates rise, narrowing the
differential between short-term and long-term interest rates, the incremental
yield pickup on the Common Stock will be reduced or eliminated completely. At
the same time, the market value of the fund's Common Stock (that is, its price
as listed on the New York Stock Exchange) may, as a result, decline.
Furthermore, if long-term interest rates rise, the Common Stock's net asset
value will reflect the full decline in the price of the portfolio's investments,
since the value of the fund's Preferred Stock does not fluctuate. In addition to
the decline in net asset value, the market value of the fund's Common Stock may
also decline.

As a part of its investment strategy, the Fund may invest in certain securities
whose potential income return is inversely related to changes in a floating
interest rate ("inverse floaters"). In general, income on inverse floaters will
decrease when short-term interest rates increase and increase when short-term
interest rates decrease. Investments in inverse floaters may be characterized as
derivative securities and may subject the Fund to the risks of reduced or
eliminated interest payments and losses of invested principal. In addition,
inverse floaters have the effect of providing investment leverage and, as a
result, the market value of such securities will generally be more volatile than
that of fixed rate, tax-exempt securities. To the extent the Fund invests in
inverse floaters, the market value of the Fund's portfolio and the net asset
value of the Fund's shares may also be more volatile than if the Fund did not
invest in these securities.

Swap
Agreements

The Fund may also invest in swap agreements, which are over-the-counter
contracts in which one party agrees to make periodic payments based on the
change in market value of a specified bond, basket of bonds, or index in return
for periodic payments based on a fixed or variable interest rate or the change
in market value of a different bond, basket of bonds or index. Swap agreements
may be used to obtain exposure to a bond or market without owning or taking
physical custody of securities.



                   MuniHoldings California Insured Fund, Inc., December 31, 2002

DEAR SHAREHOLDER

For the six months ended December 31, 2002, the Common Stock of MuniHoldings
California Insured Fund, Inc. earned $.450 per share income dividends, which
included earned and unpaid dividends of $.075. This represents a net annualized
yield of 5.80%, based on a period-end net asset value of $15.40 per share. Over
the same period, the Fund's Common Stock had a total investment return of
+7.22%, based on a change in per share net asset value from $14.82 to $15.40,
and assuming reinvestment of $.450 per share income dividends.

For the six-month period ended December 31, 2002, the Fund's Preferred Stock had
an average yield as follows: Series A, 1.18%; Series B, 1.27%; Series C, 1.10%;
Series D, 1.20%; and Series E, 1.21%.

The Municipal Market Environment

During the six-month period ended December 31, 2002, long-term fixed income
interest rates continued to move lower. As they had earlier in 2002, declining
U.S. equity markets and worldwide political tensions easily overshadowed the
incipient U.S. economic recovery allowing bond yields to fall to recent historic
low levels. In late July, second quarter 2002 gross domestic product activity
was reported at 1.1%, a significant decline from the first quarter rate of 5%.
This rate suggested that continued declines in U.S. equity prices were
negatively affecting not only consumer and business confidence but undermining
much of the economic growth seen earlier this year. Some analysts extrapolated
that recent weakness would continue, if not accelerate. This brought about
forecasts that the Federal Reserve Board would soon be obliged to lower
short-term interest rates both to offset equity market declines and boost
consumer and business spending. The possibility of lower short-term interest
rates helped push longer-term bond yields lower still during July and August.
The dramatic decline in U.S. equity prices in late August and September
triggered a significant fixed income rally as investors sought the safe-haven
status of U.S. Treasury securities. By the end of September, U.S. Treasury bond
yields had fallen to 4.66%.

Bolstered by an unexpected decline in the national unemployment rate to 5.6% in
early October, U.S. equity markets staged a strong rally throughout much of the
month. The Standard & Poor's 500 (S&P 500) Index rose over 8% for the month,
triggered by stronger-than-expected earnings reports from a large number of
companies, such as General Electric Company, International Business Machines
Corporation and Microsoft Corporation. As they have throughout most of the
period, bond prices traded in an inverse relationship to equity prices.
Consequently, as stocks rallied, bond yields rose in October, despite generally
weak economic releases. During October, the U.S. housing sector remained quite
robust, but retail sales and industrial production slowed. Fixed income bond
yields remained under pressure in November as U.S. equity markets continued to
strengthen. During November, the S&P 500 Index rose an additional 5.5%. Equity
prices were supported by signs of further U.S. economic recovery, especially
improving labor market activity. By the end of November, third quarter U.S.
gross domestic product (GDP) growth was revised to 4%. Financial conditions were
also strengthened by a larger-than-expected reduction in short-term interest
rates by the Federal Reserve Board in early November. The Federal Funds target
rate was lowered 50 basis points (.50%) to 1.25%, its lowest level since the
1960s. Recent action by the Federal Reserve Board was largely viewed as being
taken to bolster the sputtering U.S. economic recovery. Rebounding U.S. equity
markets and the prospects for a more substantial U.S. economic recovery pushed
long-term U.S. Treasury yield levels to 5.10% by late November.

In December, softer equity prices and renewed investor concerns about potential
U.S. military action against Iraq again combined to push long-term interest
rates lower. The S&P 500 Index declined more than 5% in December on
disappointing earnings reports and anticipated weak holiday sales. During
December 2002, as both national and international investors sought the
safe-haven sanctuary of U.S. Treasury issues, long-term U.S. Treasury yields
declined over 25 basis points to end the period at 4.75%. During the last six
months, long-term U.S. Treasury bond yields declined 75 basis points.

For the six-month period ended December 31, 2002, tax-exempt bond prices also
generally rose. In recent months, municipal bond yields have declined in
response to the positive fixed income environment engendered by falling equity
valuations. Price advances in tax-exempt issues have not been able to keep pace
with the U.S. Treasury bond price improvement as municipal bonds cannot offer
foreign investors the safe-haven status U.S. Treasury obligations enjoy in
periods of economic and political instability. Additionally, tax-exempt bond
issuance increased dramatically in the last half of 2002 removing some of the
positive technical support the municipal bond market enjoyed earlier this year.
By the end of 2002, long-term municipal bond yields, as measured by the Bond
Buyer Revenue Bond Index, stood at 5.16%, a decline of 25 basis points during
the last six months.

Investor demand for tax-exempt products remained positive throughout the period.
In addition to the approximately $75 billion investors received from June to
August 2002 from bond maturities, coupon income and proceeds from early
redemptions, investors are expected to receive approximately $30 billion from
these sources in January 2003. The Investment Company Institute reported that in
2002 municipal bond funds net cash flows continued to be very positive at nearly
$16 billion, an increase of more than 25% compared to 2001. However, these
positive demand factors have not been able to offset the increase in tax-exempt
new-issue supply that has resulted in the underperformance seen in recent
months. This price underperformance served to make municipal bonds a
particularly attractive purchase relative to their taxable counterparts.
Throughout most of the yield curve, municipal bonds have been available for
purchase at yields near or exceeding those of comparable U.S. Treasury issues.
Compared to their recent historical averages of 82% - 88% of U.S. Treasury
yields, municipal bond yields ratios at their current 95% -105% range are likely
to prove attractive to long-term investors.

Continued uncertainty regarding the pace of the current U.S. economic recovery
as well as the resolution of the U.N./Iraq confrontation are likely to keep
interest rates near their present levels for the immediate future. Equity market
declines over the past three years have helped push interest rates lower than
economic fundamentals alone would support. When U.S. business conditions improve
and equity markets stabilize, however, any associated interest rate increases
should not be extreme. Inflationary pressures are negligible and any move by the
Federal Reserve Board to raise short-term interest rates is unlikely before late
2003. As equity valuations are likely to only gradually recover, U.S. economic
recovery is also likely to be a moderate process. This suggests that the pace of
any interest rate increases will be gradual. As the municipal bond market's
strong technical position can be expected to remain supportive in the coming
months, future tax-exempt interest rate increases should be more restrained than
their taxable counterparts.

Specific to California, the California budget has been deteriorating because of
a stalled state economy. The budget shortfall, estimated to be nearing $34
billion, was comprised of $10 billion from the remaining fiscal year end and $24
billion for the fiscal year-end 2004. The Governor's office attributes the
deficit to a slowing national economy and a declining stock market that resulted
in lower capital gains tax revenue. The $34 billion shortfall is for the fiscal
year beginning on July 1, 2003 through the end of 2004. Governor Gray Davis
proposed a budget package including $21 billion in spending cuts and $8 billion
in higher taxes on income, retail sales and cigarettes. Standard and Poor's
lowered its credit rating on the state's general obligation debt to A from A+.
Fitch lowered its rating to A from AA, while Moody's Investors Service
maintained its rating of A1. These lowered ratings, and the perception of
increased borrowing needs in the future, caused a widening of yield spreads.
California uninsured paper had traded as tight as 5 basis points-10 basis points
to comparably structured insured bonds last year. Currently, California general
obligations trade at a 50 basis point spread to AAA-rated bonds. On a positive
note, California is still the world's fifth largest economy in terms of domestic
gross product and possesses the economic basis to address these financial
problems. In our opinion, the state's challenge is to overcome the political
obstacles to achieving financial discipline.

Portfolio Strategy

For the six-month period ended December 31, 2002, we maintained


                                      2 & 3


                   MuniHoldings California Insured Fund, Inc., December 31, 2002

a fully invested position, with cash equivalent reserves averaging less than 5%
of total assets. We minimized cash reserves because of the extremely tight
technical position of the California short-term marketplace, where yields on
cash equivalents were consistently below 1.50% throughout most of the period and
are currently below 1%. Our strategy during the past six months was aimed at
creating a more defensive market structure within a portfolio that is 40%
leveraged. We raised the Fund's overall average coupon levels and shortened
maturities through purchases in both the primary and secondary California
markets. We have become more aggressive in hedging positions, utilizing
financial futures in an effort to further seek to protect the Fund's net asset
value. The Fund's hedge was increased to a 15% position as 10-year Treasury
interest rates reached 4%.

The Fund's net asset value has recently surpassed the original issue level of
$15. Our strategy focused on protecting this price level since historically we
have witnessed a reluctance of municipal prices to move higher once the market
has achieved these levels. Retail investors repeatedly have pulled back from the
California insured municipal marketplace once absolute yields decline through
5%. As of December 2002, the market revisited these levels, and we sought to
reduce net asset volatility in the Fund from this point forward. Steps taken to
date include raising the average level of couponing of the Fund's holdings and
concentrating assets in those parts of the yield curve that we believe offer the
best value for interest rate risk taken. We have purposely underutilized the
portion of the Fund's assets that can be committed to non-insured paper. The use
of leverage allowed the Fund to generate an above-average yield. Consequently,
it has not been necessary to reach for additional yield by compromising credit
quality. At December 31, 2002, 89.5% of the Fund's long-term assets were rated
AAA by at least one of the major bond rating agencies.

The Fund employs leverage to seek to provide a generous current return of
tax-exempt income to shareholders. The additional 50 basis point decline in
short-term interest rates engineered by the Federal Reserve Board at its
November 2002 meeting resulted in a decrease in the Fund's borrowing cost. This
decline, in combination with a steep tax-exempt yield curve, generated a
material income benefit to the Fund's Common Stock shareholder from the
leveraging of the Preferred Stock. However, at this point, no further declines
in short-term interest rates are expected in the coming months, and we
anticipate that the Fund will continue to benefit from these low borrowing
costs. However, should the spread between short-term and long-term interest
rates narrow, the benefits of leverage will decline and, as a result, reduce the
yield on the Fund's Common Stock. (For a more complete explanation of the
benefits and risks of leveraging, see page 1 of this report to shareholders.)

In Conclusion

We appreciate your investment in MuniHoldings California Insured Fund, Inc., and
we look forward to assisting you with your financial needs in the months and
years ahead.

                   MuniHoldings California Insured Fund, Inc., December 31, 2002

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies:

MuniHoldings California Insured Fund, Inc. (the "Fund") is registered under the
Investment Company Act of 1940 as a non-diversified, closed-end management
investment company. The Fund's financial statements are prepared in conformity
with accounting principles generally accepted in the United States of America,
which may require the use of management accruals and estimates. These unaudited
financial statements reflect all adjustments, which are, in the opinion of
management, necessary to a fair statement of the results for the interim period
presented. All such adjustments are of a normal, recurring nature. The Fund
determines and makes available for publication the net asset value of its Common
Stock on a weekly basis. The Fund's Common Stock is listed on the New York Stock
Exchange under the symbol MUC. The following is a summary of significant
accounting policies followed by the Fund.

(a) Valuation of investments -- Municipal bonds are traded primarily in the
over-the-counter markets and are valued at the most recent bid price or yield
equivalent as obtained by the Fund's pricing service from dealers that make
markets in such securities. Financial futures contracts and options thereon,
which are traded on exchanges, are valued at their closing prices as of the
close of such exchanges. Options written or purchased are valued at the last
sale price in the case of exchange-traded options. In the case of options traded
in the over-the-counter market, valuation is the last asked price (options
written) or the last bid price (options purchased). Securities with remaining
maturities of sixty days or less are valued at amortized cost, which
approximates market value. Securities and assets for which market quotations are
not readily available are valued at fair value as determined in good faith by or
under the direction of the Board of Directors of the Fund, including valuations
furnished by a pricing service retained by the Fund, which may utilize a matrix
system for valuations. The procedures of the pricing service and its valuations
are reviewed by the officers of the Fund under the general supervision of the
Board of Directors.

(b) Derivative financial instruments -- The Fund may engage in various portfolio
investment strategies to increase or decrease the level of risk to which the
Fund is exposed more quickly and efficiently than transactions in other types of
instruments. Losses may arise due to changes in the value of the contract or if
the counterparty does not perform under the contract.

o Financial futures contracts -- The Fund may purchase or sell financial futures
contracts and options on such futures contracts for the purpose of hedging the
market risk on existing securities or the intended purchase of securities.
Futures contracts are contracts for delayed delivery of securities at a specific
future date and at a specific price or yield. Upon entering into a contract, the
Fund deposits and maintains as collateral such initial margin as required by the
exchange on which the transaction is effected. Pursuant to the contract, the
Fund agrees to receive from or pay to the broker an amount of cash equal to the
daily fluctuation in value of the contract. Such receipts or payments are known
as variation margin and are recorded by the Fund as unrealized gains or losses.
When the contract is closed, the Fund records a realized gain or loss equal to
the difference between the value of the contract at the time it was opened and
the value at the time it was closed.

o Options -- The Fund is authorized to write covered call options and purchase
put options. When the Fund writes an option, an amount equal to the premium
received by the Fund is reflected as an asset and an equivalent liability. The
amount of the liability is subsequently marked to market to reflect the current
market value of the option written. When a security is purchased or sold through
an exercise of an option, the related premium paid (or received) is added to (or
deducted from) the basis of the security acquired or deducted from (or added to)
the proceeds of the security sold. When an option expires (or the Fund enters
into a closing transaction), the Fund realizes a gain or loss on the option to
the extent of the premiums received or paid (or gain or loss to the extent the
cost of the closing transaction exceeds the premium paid or received).

Written and purchased options are non-income producing investments.

(c) Income taxes -- It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no Federal income tax provision is required.

(d) Security transactions and investment income -- Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Realized gains and losses on security transactions are determined on the
identified cost basis. Dividend income is recorded on the ex-dividend dates.
Interest income is recognized on the accrual basis.

(e) Dividends and distributions -- Dividends from net investment income are
declared and paid monthly. Distributions of capital gains are recorded on the
ex-dividend dates.

2. Investment Advisory Agreement and Transactions with Affiliates:

The Fund has entered into an Investment Advisory Agreement with Fund Asset
Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc.
("PSI"), an indirect, wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML
& Co."), which is the limited partner.

FAM is responsible for the management of the Fund's portfolio and provides the
necessary personnel, facilities, equipment and certain other services necessary
to the operations of the Fund. For such services, the Fund pays a monthly fee at
an annual rate of .55% of the Fund's average weekly net assets, including
proceeds from the issuance of Preferred Stock. For the six months ended December
31, 2002, FAM earned fees of $2,803,666, of which $200,678 was waived.

For the six months ended December 31, 2002, the Fund reimbursed FAM $11,173 for
certain accounting services.

Certain officers and/or directors of the Fund are officers and/or directors of
FAM, PSI, and/or ML & Co.

MANAGED DIVIDEND POLICY

The Fund's dividend policy is to distribute all or a portion of its net
investment income to its shareholders on a monthly basis. However, in order to
provide shareholders with a more consistent yield to the current trading price
of shares of Common Stock of the Fund, the Fund may at times pay out less than
the entire amount of net investment income earned in any particular month and
may at times in any particular month pay out such accumulated but undistributed
income in addition to net investment income earned in that month. As a result,
the dividends paid by the Fund for any particular month may be more or less than
the amount of net investment income earned by the Fund during such month. The
Fund's current accumulated but undistributed net investment income, if any, is
disclosed in the Statement of Net Assets, which comprises part of the financial
information included in this report.

MuniHoldings California Insured Fund, Inc. seeks to provide shareholders with
current income exempt from Federal and California income taxes. The Fund seeks
to achieve this objective by investing primarily in a portfolio of long-term
investment-grade municipal obligations the interest on which, in the opinion of
bond counsel to the issuer, is exempt from Federal and California income taxes.

This report, including the financial information herein, is transmitted to
shareholders of MuniHoldings California Insured Fund, Inc. for their
information. It is not a prospectus. Past performance results shown in this
report should not be considered a representation of future performance. The Fund
has leveraged its Common Stock and intends to remain leveraged by issuing
Preferred Stock to provide the Common Stock shareholders with a potentially
higher rate of return. Leverage creates risks for Common Stock shareholders,
including the likelihood of greater volatility of net asset value and market
price of shares of the Common Stock, and the risk that fluctuations in the
short-term dividend rates of the Preferred Stock may affect the yield to Common
Stock shareholders. Statements and other information herein are as dated and are
subject to change.
