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.

See Notes to Financial Statements. 16 & 17 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. 3. Investments: Purchases and sales of investments, excluding short-term securities, for the six months ended December 31, 2002 were $90,864,836 and $91,086,639, respectively. Net realized gains (losses) for the six months ended December 31, 2002 and net unrealized gains (losses) as of December 31, 2002 were as follows: - -------------------------------------------------------------------------------- Realized Unrealized Gains (Losses) Gains (Losses) - -------------------------------------------------------------------------------- Long-term investments .................. $ 4,083,683 $ 70,654,035 Financial futures contracts ............ (6,202,650) (2,887,500) ------------ ------------ Total .................................. $ (2,118,967) $ 67,766,535 ============ ============ - -------------------------------------------------------------------------------- As of December 31, 2002, net unrealized appreciation for Federal income tax purposes aggregated $70,605,407, of which $70,700,422 related to appreciated securities and $95,015 related to depreciated securities. The aggregate cost of investments at December 31, 2002 for Federal income tax purposes was $929,309,974. 4. Stock Transactions: The Fund is authorized to issue 200,000,000 shares of 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 stock without approval of holders of Common Stock. Common Stock Shares issued and outstanding during six months ended December 31, 2002 and for the year ended June 30, 2002 remained constant. Preferred Stock AMPS are shares of Preferred Stock of the Fund, with a par value of $.10 per share and a liquidation preference of 18 & 19 MuniHoldings California Insured Fund, Inc., December 31, 2002 NOTES TO FINANCIAL STATEMENTS (concluded) $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 December 31, 2002 were: Series A, 1.475%; Series B, .909%; Series C, 1.10%; Series D, 1.49%; and Series E, 1.549%. 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 six months ended December 31, 2002, Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S") earned $196,569 as commissions. 5. Distributions to Shareholders: On January 7, 2003, a tax-exempt income dividend of $.075000 was declared. The dividend was paid on January 30, 2003, to shareholders of record on January 16, 2003. 6. Capital Loss Carryforward: On June 30, 2002, the Fund had a net capital loss carryforward of $45,571,244, of which $911,162 expires in 2006; $11,978,510 expires in 2007; $7,894,678 expires in 2008 and $24,786,894 expires in 2009. This amount will be available to offset like amounts of any future taxable gains. 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. 20 & 21 MuniHoldings California Insured Fund, Inc., December 31, 2002 QUALITY PROFILE The quality ratings of securities in the Fund as of December 31, 2002 were as follows: - -------------------------------------------------------------------------------- Percent of S&P Rating/Moody's Rating Total Investments - -------------------------------------------------------------------------------- AAA/Aaa .................................................. 89.5% AA/Aa .................................................... 1.9 A/A ...................................................... 1.8 BBB/Baa .................................................. 2.9 NR (Not rated) ........................................... 1.3 Other+ ................................................... 2.6 - -------------------------------------------------------------------------------- + Temporary investments in short-term municipal securities.

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. MuniHoldings California Insured Fund, Inc.
