Dear Stockholder:

         Recently, you received a joint proxy statement and prospectus
describing a proposed reorganization of the listed funds in which MuniHoldings
California Insured Fund II, Inc. (the "surviving fund") would acquire the assets
and assume the liabilities of MuniHoldings California Insured Fund, Inc.,
MuniHoldings California Insured Fund III, Inc., and MuniHoldings California
Insured Fund IV, Inc. in exchange for shares of the common stock and auction
market preferred stock of the surviving fund. At the time the proxy statement
and prospectus was mailed, the audited financial statements of the funds with a
fiscal year ending September 30, 1999 were not available.

         For that reason and in order to ensure that you have all the
information you might need about the proposed reorganization, we have enclosed
the Annual Report to Stockholders of MuniHoldings California Insured Fund IV,
Inc. which contains that fund's audited financial statements for the year ended
September 30, 1999.

         If you have not yet completed and returned your proxy card we urge you
to do so now. Your vote is important. If you have any questions regarding the
meeting agenda or the execution of your proxy, please call Shareholder
Communications Corporation at 1-800-645-4519.

The Benefits and
Risks of
Leveraging

MuniHoldings California Insured Fund IV, Inc. has the ability to 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

Since inception (January 29, 1999) through September 30, 1999, the Common Stock
of MuniHoldings California Insured Fund IV, Inc. earned $0.540 per share income
dividends, which included earned and unpaid dividends of $0.068. This represents
a net annualized yield of 6.28%, based on a month-end net asset value of $12.81
per share. During the same period, the total investment return on the Fund's
Common Stock was -11.61%, based on a change in per share net asset value from
$15.00 to $12.81, and assuming reinvestment of $0.472 per share income
dividends.

For the six-month period ended September 30, 1999, the Fund's Auction Market
Preferred Stock had an average yield of 2.86% for Series A and 3.01% for Series
B.

The Municipal Market Environment

The combination of steady strong domestic economic growth, improvement in
foreign economies (most notably in Japan) and increasing investor concerns
regarding potential increases in US inflation put upward pressure on bond yields
throughout the six-month period ended September 30, 1999. Continued strong US
employment growth, particularly the decline in the US unemployment rate to 4.2%
in early June, was among the reasons the Federal Reserve Board cited for raising
short-term interest rates in late June and again in late August. US Treasury
bond yields reacted by climbing above 6.25% by mid-August before improving
somewhat to 6.05% by September 30, 1999. During the period, yields on 30-year US
Treasury bonds increased over 40 basis points (0.40%).

Long-term tax-exempt bond yields also rose during the six months ended September
30, 1999. Until early May, the municipal bond market was able to withstand much
of the upward pressure on bond yields. However, investor concerns of additional
moves by the Federal Reserve Board to moderate US economic growth and, more
importantly, the loss of the strong technical support that the tax-exempt market
enjoyed in early 1999 helped push municipal bond yields significantly higher for
the remainder of the period. The yields on long-term tax-exempt revenue bonds
rose over 65 basis points to 5.96% by September 30, 1999, as measured by the
Bond Buyer Revenue Bond Index.

In recent months, the significant decline in new tax-exempt bond issuance has
remained a positive factor within the municipal bond market, as it had been for
much of the past year. During the last six months, more than $113 billion in
long-term municipal bonds was issued, a decline of over 20% compared to the same
period a year ago. During the past three months, $55 billion in municipal bonds
was underwritten, representing a decline of nearly 15% compared to the
corresponding period in 1998. Additionally, in June and July, investors received
more than $40 billion in coupon income and proceeds from bond maturities and
early bond redemptions. These proceeds have generated considerable retail
investor interest, which has helped absorb the recent diminished supply.

Although tax-exempt bond yields are at their highest level in over two years and
have attracted significant retail investor interest, institutional demand has
declined sharply. Long-term municipal 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. In addition, the demand from
property/casualty insurance companies has weakened as a result of the losses,
and anticipated losses, incurred as a result of the series of damaging storms
across much of the eastern United States. Additionally, many institutional
investors who were attracted to the municipal bond market in recent years by
historically attractive tax-exempt bond yield ratios of over 90% have found
other asset classes even more attractive. Even with a reduced supply position,
tax-exempt issuers have been forced to repeatedly raise municipal bond yields in
the attempt to attract adequate demand.

The recent relative underperformance of the municipal bond market has resulted
in an opportunity for long-term investors to purchase tax-exempt issues whose
yields are nearly identical to taxable US Treasury securities. At September 30,
1999, long-term uninsured municipal revenue bond yields were almost 99% of
comparable US Treasury securities. In recent months, many taxable asset classes,
such as corporate bonds, mortgage-backed securities and US agency debt, have all
accelerated debt issuance. This acceleration was initiated largely to avoid
issuing securities at year-end and to minimize any associated Year 2000 (Y2K)
problems that may develop. However, this increased issuance has also resulted in
higher yield levels in the various asset classes as lower bond prices became
necessary to attract sufficient investor demand. Going forward, it is believed
that the pace of non-US Government debt issuance is likely to slow
significantly. As the supply of this debt declines, we would expect many
institutional investors to return to the municipal bond market and the
attractive yield ratios available.

Looking ahead, it appears to us that long-term municipal bond yields will remain
under pressure, trading in a broad range centered near current levels. Investors
are likely to remain concerned about future action by the Federal Reserve Board.
Y2K considerations may prohibit a series of Federal Reserve Board moves at the
end of the year and the beginning of 2000. Any improvement in bond prices will
probably be contingent upon weakening in both US employment growth and consumer
spending. The 100 basis point rise in US Treasury bond yields seen thus far this
year may negatively affect US economic growth. The US housing market will be
among the first sectors likely to be affected, as some declines have already
been evidenced in response to higher mortgage rates. We believe that it is also
unrealistic to expect double-digit returns in US equity markets to continue
indefinitely. Much of the US consumer's wealth is tied to recent stock market
appreciation. Any slowing in these incredible growth rates is likely to reduce
consumer spending. We believe that these factors suggest that the worst of the
recent increase in bond yields has passed and stable, if not slightly improving,
bond prices may be expected.

In Conclusion

On September 9, 1999, MuniHoldings California Insured Fund IV, Inc.'s Board of
Directors approved a plan of reorganization, subject to shareholder approval and
certain other conditions, whereby MuniHoldings California Insured Fund II, Inc.
would acquire substantially all of the assets and liabilities of the Fund,
MuniHoldings California Insured Fund Inc. and MuniHoldings California Insured
Fund III, Inc. in exchange for newly issued shares of MuniHoldings California
Insured Fund II, Inc. These Funds are registered, non-diversified, closed-end
management investment companies. All four entities have similar investment
objectives and are managed by Fund Asset Management, L.P.

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies:

MuniHoldings California Insured Fund IV, 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 accordance
with generally accepted accounting principles, which may require the use of
management accruals and estimates. Prior to commencement of operations on
January 29, 1999, the Fund had no operations other than those relating to
organizational matters and the sale of 6,667 shares of Common Stock on January
13, 1999 to Fund Asset Management, L.P. ("FAM") for $100,005. The Fund's Common
Stock is listed on the New York Stock Exchange under the symbol CIL. 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.

NOTES TO FINANCIAL STATEMENTS (concluded)

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 transac
tion), 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) Offering expenses--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.

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 period January 29, 1999 to September
30, 1999 increased by 9,860,000 from shares sold and by 32,604 as a result of
dividend reinvestment.

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
September 30, 1999 were as follows: Series A, 3.25% and Series B, 3.49%.

In connection with the offering of AMPS, the Board of Directors has reclassified
3,640 shares of unissued capital stock as AMPS. Shares issued and outstanding
during the period January 29, 1999 to September 30, 1999 increased by 3,640 as a

at an annual rate ranging from .25% to .375%, calculated on the proceeds of each
auction. For the period January 29, 1999 to September 30, 1999, MLPF&S, an
affiliate of FAM, earned $115,447 as commissions.

5. Capital Loss Carryforward:

At September 30, 1999, the Fund had a net capital loss carryforward of

MANAGED DIVIDEND POLICY

The Fund's dividend policy is to distribute substantially all 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 particu lar 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.

information. It is not a prospectus, circular or representation intended for use
in the purchase of shares of the Fund or any securities mentioned in the report.
Past performance results shown in this report should not be considered a

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.
