MuniHoldings California Insured Fund, Inc.

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.

DEAR SHAREHOLDER

We are pleased to provide this annual report to shareholders. As a result of the
Fund's recent reorganization, the Fund has changed its name from MuniHoldings
California Insured Fund II, Inc. to MuniHoldings California Insured Fund, Inc.
For complete information about the Fund's reorganization, see Note 6 on pages 19
and 20 of this report to shareholders.

For the year ended June 30, 2000, the Common Stock of MuniHoldings California
Insured Fund, Inc. earned $0.808 per share income dividends, which included
earned and unpaid dividends of $0.062. This represents a net annualized yield of
6.07%, based on a month-end net asset value of $13.31 per share. Over the same
period, the Fund's Common Stock had a total investment return of -1.23%, based
on a change in per share net asset value from $14.38 to $13.31, and assuming
reinvestment of $0.815 per share income dividends.

For the six-month period ended June 30, 2000, the Fund's Common Stock had a
total investment return of +10.03%, based on a change in per share net asset
value from $12.49 to $13.31, and assuming reinvestment of $0.395 per share
income dividends.

For the year ended June 30, 2000, the Fund's Preferred Stock had an average
yield as follows: Series A, 3.76%; Series B, 3.47%; Series C, 3.54%; Series D,
3.59%; and Series E, 3.91%.

The Municipal Market Environment

At the start of the year, fixed-income bond yields were initially pushed higher
as US economic growth remained robust. After growing at a 7.3% rate during the
fourth quarter of 1999 and a 4.2% annual rate for all of 1999, first quarter of
2000 gross domestic product growth was 5.5%. However, despite these significant
growth rates, few price measures showed any meaningful signs of future price
pressures at the consumer level, despite the lowest unemployment rates since
January 1970 and rising energy prices. With few signs of any economic slowdown,
the Federal Reserve Board continued to raise short-term interest rates in
February, March and May 2000. The Federal Reserve Board cited both the continued
growth of US employment and the continued strength of US equity markets as
reasons for attempting to moderate US economic growth before inflationary price
increases can be realized. By late January 2000, US Treasury bond yields rose
more than 25 basis points (0.25%) to 6.75%. Similarly, as measured by the Bond
Buyer Revenue Bond Index, long-term, tax-exempt bond yields rose approximately
15 basis points to 6.35%.

Since then, however, fixed-income markets have largely ignored strong economic
fundamentals and concentrated upon very positive technical supply factors.
Declining bond issuance--both current, and more importantly, expected future
issuance--helped push bond yields lower from late-January to mid-April 2000. In
late January and early February 2000, the US Treasury announced its intention to
reduce the amounts to be auctioned in quarterly Treasury note and bond auctions.
Furthermore, budgetary surpluses allowed the US Treasury to repurchase
outstanding, higher-couponed Treasury issues, primarily in the 15-year and
longer maturity sector. Both of these actions resulted in a significant
reduction in the outstanding supply of longer-dated maturity US Treasury debt.
Domestic and international investors quickly began to accumulate what was
expected to become a scarce commodity and bond prices quickly rose.

By mid-April 2000, US Treasury bond yields had declined more than 100 basis
points to 5.67%. However, bond yields rose somewhat during the remainder of the
period as economic statistics were released indicating that the economic
strength seen in late 1999 was continuing into early 2000. The domestic decline
in long-term US Treasury yields resulted in an inverted yield curve as
short-term and intermediate-term interest rates did not fall proportionately to
long-term interest rates as the Federal Reserve Board was expected to continue
to raise short-term interest rates. The current inversion has had much more to
do with debt reduction and Treasury buy-backs than with market expectations of
slower economic growth. During the last six months, long-term US Treasury bond
yields have fallen almost 60 basis points to end the period at 5.90%.

Tax-exempt bond yields also have declined in recent months. The decline has
largely been in response to the rally in US Treasury securities, as well as a
continued positive technical supply environment. States such as California and
Maryland have announced that their large current and anticipated future budget
surpluses will permit the cancellation or postponement of expected bond
issuance. Additionally, some issuers have initiated tenders to repurchase
existing debt, reducing the supply of tax-exempt bonds in the secondary market
as well. Since their recent peak in January 2000, long-term municipal bond
yields have declined more than 30 basis points to finish the six-month period
ended June 30, 2000 at 5.90%.

The relative underperformance of the municipal bond market in recent months has
been especially disappointing given the strong technical position the tax-exempt
bond market has enjoyed. The issuance of long-term, tax-exempt securities has
dramatically declined. During the last year, $199 billion in new long-term
municipal securities was issued, a decline of almost 20% versus the same period
a year earlier. For the six months ended June 30, 2000, approximately $90
billion in new tax-exempt bonds was underwritten, a decline of more than 20%
compared to the same period in 1999.

Although investors received over $30 billion in coupon payments, bond maturities
and the proceeds from early bond redemptions during January and February, and
expect to receive a similar amount on June 1 and July 1, 2000, along with the
highest municipal bond yields in three years, overall investor demand has
diminished. Long-term municipal bond mutual funds have seen consistent outflows
in recent months as the yields of individual securities have risen faster than
those of larger, more diverse mutual funds. Thus far this year, tax-exempt
mutual funds have had net redemptions of more than $12 billion. Also, the demand
from property and casualty insurance companies has weakened as a result of the
losses incurred from a series of damaging storms across much of the eastern
United States. Additionally, many institutional investors who have in recent
years been drawn to the municipal bond market by historically attractive
tax-exempt bond yield ratios of more than 90% have found other asset classes
even more compelling. Even with a favorable supply position, tax-exempt
municipal bond yields have underperformed their taxable counterparts.

Significantly lower municipal bond yields are still likely to require weaker US
employment growth and consumer spending. The actions taken in recent months by
the Federal Reserve Board, as well as the expected action in August 2000, will
eventually slow US economic growth. Recent declines in US new home sales are
perhaps among the first signs that consumer spending is being slowed by higher
interest rates. Until further signs develop, it is likely that the municipal
bond market's current favorable technical position will dampen significant
tax-exempt interest rate volatility and provide a stable environment for
eventual improvement in municipal bond prices.

Portfolio Strategy

MuniHoldings California Insured Fund, Inc. has been structured to seek to
deliver a high current return of tax-exempt income to California residents by
maintaining a fully invested and leveraged position. The effects of leverage
benefited the Fund's Common Stock yield because of the positive slope of the
municipal yield curve. However, should the spread between long-term and
short-term interest rates narrow, the benefits of leverage will decline and the
yield on the Fund's Common Stock will decline. (For a complete explanation of
the benefits and risks of leveraging, see page 1 of this report to
shareholders.) Our primary investment strategy has been to increase the average
level of couponing in the Fund, while taking advantage of a relatively flat
municipal yield curve to shorten average maturity. During periods of rising
interest rates, primary issuance provides us with opportunities to restructure
the Fund. These holdings can provide a higher current yield with less exposure
to the longer maturity range of the municipal marketplace. However, credit
quality has been one of our primary concerns. We are purposely underutilizing
the portion of assets that can be committed to uninsured securities. This helped
the Fund's performance during the recent period of widening credit quality
spreads. We expect to continue the process of raising average coupon structure
and reducing duration in an effort to temper the Fund's volatility and exposure
to long-term interest rate swings.

In Conclusion

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

Sincerely,

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies:

MuniHoldings California Insured Fund, Inc. (the "Fund") (formerly MuniHoldings
California Insured Fund II, Inc.) 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 accordance with accounting
principles generally accepted in the United States of America, which may require
the use of management accruals and estimates. 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

NOTES TO FINANCIAL STATEMENTS (continued)

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).
Interest income is recognized on the accrual basis. Discounts and market
premiums are amortized into interest income. Realized gains and losses on
security transactions are determined on the identified cost basis.

(e) Organization and offering expenses -- In accordance with Statement of
Position 98-5, unamortized organization expenses of $11,898 were expensed during
the year ended June 30, 2000. This is considered to be a change in accounting
principle and had no material impact on the operations of the Fund. Direct
expenses relating to the public offering of the Fund's Common and Preferred
Stock were charged to capital at the time of issuance of the shares.

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

(g) Reclassification -- Generally accepted accounting principles require that
certain components of net assets be adjusted to reflect permanent differences
between financial and tax reporting. Accordingly, current year's permanent
book/tax differences of $447,161 have been reclassified between paid-in capital
in excess of par and undistributed net investment income. These
reclassifications have no effect on net assets or net asset value per share.

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 year ended June 30, 2000,
FAM earned fees of $2,266,567, of which $265,093 was voluntarily waived.

Accounting services are provided to the Fund by FAM at cost.

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

3. Investments:

4. Capital Stock Transactions:

The Fund is authorized to issue 200,000,000 shares of capital stock, including
Preferred Stock, par value $.10 per share, all of which were initially
classified as Common Stock. The Board of Directors is authorized, however, to
reclassify any unissued shares of capital stock without approval of holders of
Common Stock.

Common Stock

Shares issued and outstanding during the year ended June 30, 2000 increased by
25,375,893 as a result of issuance of Common Stock from reorganization and by
11,885 as a result of dividend reinvestment. Shares issued and outstanding
during the year ended June 30, 1999 remained constant.

Preferred Stock

Auction Market Preferred Stock ("AMPS") are shares of Preferred Stock of the
Fund, with a par value of $.10 per share and a liquidation preference of $25,000
per share that entitle their holders to receive cash dividends at an annual rate
that may vary for the successive dividend periods. The yields in effect at June
30, 2000 were: Series A, 3.50%; Series B, 3.50%; Series C, 3.50%; Series D,
4.70%; and Series E, 4.70%.

Shares issued and outstanding during the year ended June 30, 2000 increased by
9,800 as a result of issuance of Preferred Stock from reorganization. Shares
issued and outstanding during the year ended June 30, 1999 remained constant.

The Fund pays commissions to certain broker-dealers at the end of each auction
at an annual rate ranging from .25% to .375%, calculated on the proceeds of each
auction. For the year ended June 30, 2000, MLPF&S earned $216,658 as
commissions.

5. Capital Loss Carryforward:

At June 30, 2000, the Fund had a net capital loss carryforward of approximately
$21,908,000, of which $4,346,000 expires in 2006, $11,359,000 expires in 2007
and $6,203,000 expires in 2008. This amount will be available to offset like
amounts of any future taxable gains.

in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements and the financial highlights are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned at June 30, 2000 by correspondence with the custodian and
brokers. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial position of MuniHoldings
California Insured Fund, Inc. as of June 30, 2000, the results of its
operations, the changes in its net assets, and the financial highlights for the
respective stated periods in accordance with accounting principles generally
accepted in the United States of America.

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 Assets, Liabilities and Capital, 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 by investing
primarily in a portfolio of long-term investment grade municipal obligations the
interest of 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 the ability to leverage its Common Stock 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.
