[LOGO] Merrill Lynch Investment Managers Semi-Annual Report January 31, 2001 MuniHoldings New Jersey Insured Fund, Inc. www.mlim.ml.com MuniHoldings New Jersey Insured Fund, Inc. The Benefits and Risks of Leveraging MuniHoldings New Jersey 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 investment 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. MuniHoldings New Jersey Insured Fund, Inc., January 31, 2001 TO OUR SHAREHOLDERS For the six-month period ended January 31, 2001, the Common Stock of MuniHoldings New Jersey Insured Fund, Inc. earned $0.358 per share income dividends, which included earned and unpaid dividends of $0.060. This represents a net annualized yield of 5.00%, based on a month-end net asset value of $14.20 per share. Over the same period, the total investment return on the Fund's Common Stock was +11.32%, based on a change in per share net asset value from $13.14 to $14.20, and assuming reinvestment of $0.357 per share income dividends. For the six months ended January 31, 2001, the Fund's Auction Market Preferred Stock had an average yield as follows: Series A, 3.62%; Series B, 4.00%; Series C, 3.87%; and Series D, 4.09%. The Municipal Market Environment During the six months ended January 31, 2001, long-term fixed-income bond yields generally declined. The strength seen in the US economy in 1999 and early 2000 clearly has moderated in recent months. After growing at approximately 5% in the first half of 2000, US gross domestic product (GDP) declined to 2.2% during the third quarter of 2000. An initial estimate of fourth quarter 2000 GDP growth was recently released at 1.4%. Additionally, over the past six months, inflationary pressures have remained well contained, largely in the 2%-3% range. By early September, US Treasury bond yields had declined more than 20 basis points (0.20%) to 5.65% as a result of moderating economic growth and low inflation. However, rising oil and natural gas prices, rekindled investors' inflationary fears, and US Treasury bond yields quickly rose to nearly 6% at the end of September 2000. During October and into mid-November, long-term bond yields fluctuated in response to declining commodity prices and the considerable uncertainty surrounding the presidential election. In December 2000, significant declines in US equity markets, especially the NASDAQ, as well as another series of weak economic indicators, combined to reestablish the decline in long-term US Treasury bond yields. By mid-December, the Federal Reserve Board announced that current economic conditions warranted the cessation of the series of short-term interest rate increases they had initiated in February 2000. Given the favorable economic environment and, at least, a neutral Federal Reserve Board, investors were free again to focus upon the ongoing US Treasury debt reduction program and forecasts of sizeable Federal budgetary surpluses going forward. Many analysts and investors concluded that there would be a significant future shortage of longer maturing US Treasury securities. These factors helped push US Treasury bond yields lower. By the end of December, US Treasury bond yields declined to 5.45%, their lowest monthly closing level in almost two years. Citing declining consumer confidence and weakening industrial production and retail sales growth, the Federal Reserve Board lowered short-term interest rates by 50 basis points twice during January 2001. This action triggered a significant rebound in many US equity indexes, reducing the appeal of many US fixed-income securities. Additionally, many investors sold US Treasury bonds to realize recent profits believing that the Federal Reserve Board's actions in January 2001, as well as those anticipated in the near future, would quickly restore US economic growth to earlier levels. By the end of the six-month period ended January 31, 2001, US Treasury bond yields declined overall by nearly 30 basis points to close the period at 5.50%. Long-term tax-exempt bonds also responded well to the positive economic environment that developed during the last six months. While municipal bond yields followed a downward pattern similar to that of US Treasury bonds, tax-exempt bond price volatility was significantly reduced. Municipal bond yields traded in a relatively narrow range, generally declining steadily throughout the last six months. Overall investor demand for municipal bonds has remained very positive, allowing tax-exempt bond yields, as measured by the Bond Buyer Revenue Bond Index, to decline more than 40 basis points to end the period at 5.43%, their lowest monthly closing level in over 18 months. New long-term tax-exempt issuance has continued to decline on an annual basis, although declines in bond yields have triggered a recent increase in municipal underwritings. Most of this recent increase in tax-exempt issuance was underwritten in January 2001. Lower bond yields were responsible for the significant increase in refunding activity. Local and state issuers used the recent period of lower bond yields as an opportunity to refinance outstanding, higher-couponed debt issues at lower rates. Historically, January monthly underwritings are among the lowest monthly issuance of the year. Despite the surge in January issuance, long-term tax-exempt bond yields were still able to decline, underscoring the ongoing positive technical position the municipal market has enjoyed in recent quarters. The reduction in annual issuance has helped provide much of the technical support within the tax-exempt bond market. The demand for municipal bonds came from a number of non-traditional and conventional sources. Fortunately, the combination of reduced annual bond issuance and ongoing demand from non-traditional sources has been able to more than offset the decline in demand from tax-exempt mutual funds. This favorable balance has fostered the significant decline in municipal bond yields seen in recent months. The outlook for the tax-exempt bond market in 2001 appears quite favorable. The steeply positive yield curve and relatively high credit quality that the municipal bond market offers should continue to attract retail and institutional investors seeking both tax-exempt income and a ready substitute for relatively scarce US Government securities. Strong state and local governmental financial conditions also suggest that issuance should remain manageable in the coming months. Additionally, while it appears likely that President Bush will keep his campaign promise to lower Federal income tax rates in 2001, any legislation is unlikely to be enacted before late summer. These factors suggest that the strong technical position the municipal market has enjoyed is likely to continue. Given the recent market performance by tax-exempt bonds over the past year, the strong returns illustrate the excellent investment diversification municipal bonds can provide to investors. Portfolio Strategy During the six months ended January 31, 2001, we continued to seek to reduce the volatility of the Fund. With signs of a decline in US economic growth and consumer confidence, there was a significant decrease in New Jersey municipal bond interest rates beginning in November 2000 that continued through January 2001. As interest rates fell, we maintained our strategy of selling interest rate-sensitive issues. With the proceeds, we purchased bonds with a maturity range of 15 years-20 years. New-issue supply was down 15% compared to the same six-month period a year ago, making Fund restructuring difficult. Going forward, we expect to maintain the Fund's neutral position and keep the Fund fully invested in an effort to enhance shareholder income. In Conclusion We appreciate your ongoing interest in MuniHoldings New Jersey Insured Fund, Inc., and we look forward to serving your investment needs in the months and years ahead.

See Notes to Financial Statements. 14 & 15 MuniHoldings New Jersey Insured Fund, Inc., January 31, 2001 NOTES TO FINANCIAL STATEMENTS 1. Significant Accounting Policies: MuniHoldings New Jersey 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 MUJ. 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 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 call and 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. The Fund will adopt the provisions of the AICPA Audit and Accounting Guide for Investment Companies, as revised, effective for fiscal years beginning after December 15, 2000. As required, the Fund will amortize premiums and discounts on debt securities under a different method effective August 1, 2001. The cumulative effect of this accounting change will have no impact on the total net assets of the Fund. The impact of this accounting change has not been determined, but will result in an adjustment to cost of securities and a corresponding adjustment in net unrealized appreciation/depreciation, based on securities held as of July 31, 2001. (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. Distributions in excess of realized capital gains are due primarily to differing tax treatments for futures transactions and post-October losses. 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 January 31, 2001, FAM earned fees of $1,153,158, of which $158,295 was waived. Accounting services were provided to the Fund by FAM through December 31, 2000. Up to this date, the Fund reimbursed FAM $70,495 for these services. As of January 1, 2001, accounting services are provided for the Fund by State Street Bank and Trust Company ("State Street") pursuant to an agreement between State Street and the Fund. The Fund will pay the cost of these services. In addition, the Fund will reimburse FAM for the cost of certain additional 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 January 31, 2001 were $100,480,168 and $132,754,246, respectively. Net realized losses for the six months ended January 31, 2001 and net unrealized gains as of January 31, 2001 were as follows: -------------------------------------------------------------------------------- Realized Unrealized Losses Gains -------------------------------------------------------------------------------- Long-term investments ..................... $(1,628,165) $ 13,953,643 ----------- ------------ Total ..................................... $(1,628,165) $ 13,953,643 =========== ============ -------------------------------------------------------------------------------- As of January 31, 2001, net unrealized appreciation for Federal income tax purposes aggregated $13,953,643, of which $15,661,003 related to appreciated securities and $1,707,360 related to depreciated securities. The aggregate cost of investments at January 31, 2001 for Federal income tax purposes was $398,457,281. 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 16 & 17 MuniHoldings New Jersey Insured Fund, Inc., January 31, 2001 NOTES TO FINANCIAL STATEMENTS (concluded) 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 six months ended January 31, 2001 remained constant and during the year ended July 31, 2000 increased by 10,816,659 as a result of reorganization. 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 January 31, 2001 were Series A, 3.95%; Series B, 4.05%; Series C, 3.09% and Series D, 3.50%. Shares issued and outstanding during the six months ended January 31, 2001 remained constant and during the year ended July 31, 2000 increased by 4,280 as a result of reorganization. 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 January 31, 2001, Merrill Lynch, Pierce, Fenner & Smith Incorporated, an affiliate of FAM, earned $102,992 as commissions. 5. Capital Loss Carryforward: At July 31, 2000, the Fund had a net capital loss carryforward of approximately $7,536,000, of which $523,000 expires in 2006, $6,464,000 expires in 2007 and $549,000 expires in 2008. This amount will be available to offset like amounts of any future taxable gains. 6. Reorganization Plan: On March 2, 2001, the Fund acquired all of the net assets of MuniHoldings New Jersey Insured Fund IV, Inc. pursuant to a plan of reorganization approved by the Board of Directors and shareholders. 7. Subsequent Event: On February 7, 2001, the Fund's Board of Directors declared an ordinary income dividend to Common Stock shareholders in the amount of $.060419 per share, payable on February 23, 2001 to shareholders of record as of February 16, 2001. 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. 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.
