-------------------------------------------------------------------------------- THE BLACKROCK CALIFORNIA INVESTMENT QUALITY MUNICIPAL TRUST INC. SEMI-ANNUAL REPORT TO SHAREHOLDERS REPORT OF INVESTMENT ADVISOR -------------------------------------------------------------------------------- May 31, 2001 Dear Shareholder: The semi-annual period was marked by the Federal Reserve's aggressive response to the dramatic U.S. led global economic slowdown. Economic weakness intensified as Gross Domestic Product ("GDP") growth slowed to a pace of 2% from 3% over the six-month period. The U.S. slowdown was primarily driven by a near collapse in corporate spending and expansion as profits declined, as well as a significant reduction of inventories. In the first quarter of 2001, the U.S. Treasury yield curve steepening of 100 basis points between 2-year and 30-year Treasuries dominated performance in the fixed income market as the Fed eased the discount rate 150 basis points over the quarter and then an additional 50 basis points in April 2001 to 4.50%. Despite the aggressive Fed easing of interest rates due to concerns that economic activity may continue to be "unacceptably weak," all high quality spread sectors outperformed Treasuries over the period. Since March 2000, there has been an equity market decline of approximately 20%. With no immediate stimulus, this decline will place significant reliance on monetary policy. Looking forward, we believe the revival of profit growth and continued robust spending rates by consumers in the face of a negative savings rate may require a Fed funds rate of 3.5% to 4.0%. A Fed that can move aggressively as inflationary expectations move down should continue to foster increased risk tolerances in the market. While the direct beneficiaries of declining inflation and Treasury surpluses should be short and intermediate Treasuries, the longer-term beneficiary should be the long-end of the Treasury market, particularly 15-year to 20-year Treasuries. We believe investors will more readily embrace high quality spread assets as substitutes for intermediate Treasuries in the future. We also believe that the GDP growth rate will remain far below the 5.0% of 2000, as consumers spend less and save more. This semi-annual report contains a summary of market conditions during the semi-annual period and a review of portfolio strategy by your Trust's managers in addition to the Trust's unaudited financial statements and a detailed list of the portfolio's holdings. Continued thanks for your confidence in BlackRock. We appreciate the opportunity to help you achieve your long-term investment goals. Sincerely, /s/ Laurence D. Fink /s/ Ralph L. Schlosstein -------------------- ------------------------ Laurence D. Fink Ralph L. Schlosstein Chairman President 2 May 31, 2001 Dear Shareholder: We are pleased to present the unaudited semi-annual report for The BlackRock California Investment Quality Municipal Trust Inc. ("the Trust") for the six months ended April 30, 2001. We would like to take this opportunity to review the Trust's stock price and net asset value (NAV) performance, summarize market developments and discuss recent portfolio management activity. The Trust is a non-diversified, actively managed closed-end bond fund whose shares are traded on the American Stock Exchange under the symbol "RAA". The Trust's investment objective is to provide high current income that is exempt from regular federal and California income taxes consistent with the preservation of capital. The Trust seeks to achieve this objective by investing in investment grade (rated "AAA" to "BBB" by a major rating agency or of equivalent quality) municipal debt securities issued by local municipalities throughout California. The table below summarizes the changes in the Trust's stock price and NAV over the past six months: ------------------------------------------------------ 4/30/01 10/31/00 CHANGE HIGH LOW -------------------------------------------------------------------------------- STOCK PRICE $15.10 $14.00 7.86% $15.35 $13.25 -------------------------------------------------------------------------------- NET ASSET VALUE (NAV) $14.77 $14.62 1.03% $15.11 $14.59 -------------------------------------------------------------------------------- THE FIXED INCOME MARKETS Investor hopes for a soft landing quickly turned to fears of a recession as the U.S. economy rapidly deteriorated over the first part of the period. This economic weakness intensified in the beginning of 2001 as GDP growth slowed over the six-month period to 2% from 3%. Increasing pressure on corporate profits restrained investment spending, subsequently reducing the demand for capital goods and output. Despite eroding consumer confidence, slower economic growth, mounting layoffs, and the reduction of over $5 trillion of wealth from the decline of the equity markets from their early year 2000 highs, the consumer remains relatively resilient. According to the minutes of the April 18, 2001 Federal Open Market Committee meeting, "Capital investment has continued to soften and the persistent erosion in current and expected profitability, in combination with rising uncertainty about the business outlook, seems poised to dampen capital spending going forward. This potential restraint, together with the possible effects of earlier reductions in equity wealth on consumption and the risk of slower growth abroad, threatens to keep the pace of economic activity unacceptably weak." Over the period, the Federal Reserve aggressively lowered the discount rate by a total of 2.00% to bring the current discount rate to 4.50%. Additionally, at the May meeting, the Fed cut rates by 50 basis points for the fifth time this year. U.S. Treasury yields began to regain their characteristic slopes in the beginning of the period after nearly a year of inversion caused by $30 billion of Treasury buybacks and multiple Federal Reserve tightenings. The 2-year Treasury note rallied in response to a slumping economy and a volatile equity market. The markets have been further supported by Fed actions, which cut rates by 50 basis points on four occasions over the period. The yield curve at the end of the period reflected expectations of another 100 basis points of easing by September. As of April 30, 2001, the 10-year Treasury was yielding 5.34% versus 5.75% on October 31, 2000. On a tax-adjusted basis, municipal bonds outperformed the taxable domestic bond market for the semi-annual period ending April 30, 2001, returning 7.27% (as measured by the LEHMAN MUNICIPAL INDEX at a tax bracket of 39.6%) versus the LEHMAN AGGREGATE INDEX'S 6.22%. Throughout this period, municipals performed in line with spread products and Treasuries. Municipals benefited from retail's continued efforts to diversify out of equities and into fixed income investments. In a dramatic reversal from most of 2000, the semi-annual period finally saw municipal mutual fund portfolios experience positive cash flows. The retail market took a renewed interest in municipals driven primarily by the turmoil experienced in equities, while institutional demand for municipal securities increased as investors looked for attractive after tax yields vs. Treasuries without the inherent credit risk associated with corporate bonds. As a result of falling interest rates during the second half of the period, new issue supply rose substantially above last year's pace. California's dynamic economic expansion continued through 2000 and into 2001. This growth will be challenged now by rising energy costs, the fall in the NASDAQ and weakening demand in the computer service industries. In April 2001, the unem 2 ployment rate was 4.8%, lower than the 5.0% of a year ago but slightly up from February's 4.5% level. The State is beginning to see a decline in growth as evidenced by fewer new jobs being created although employment still continues to grow. The State of California's year-to-date revenues are slightly above projected levels. However, in March 2001 personal income tax, sales tax and corporate tax receipts were slightly below budget, additional evidence of a slowing economy. Furthermore, since January the State has been using its General Fund surplus to purchase energy for the States' three crippled utilities and to date it has expended over $6 billion. In response to the energy crisis, Moody's Investors Services and Standard & Poor's have lowered California's credit rating to Aa3/A+ from Aa2/AA and the credit outlook remains negative on the State's general obligation bonds. We are monitoring our California State holdings and watching the energy impact on the economy and local issuers. THE TRUST'S PORTFOLIO AND INVESTMENT STRATEGY The Trust's portfolio is actively managed to diversify exposure to various sectors, issuers, revenue sources and security types. BlackRock's investment strategy emphasizes a relative value approach, which allows the Trust to capitalize upon changing market conditions by rotating municipal sectors, credits and coupons. Additionally, the Trust employs leverage to enhance its income by borrowing at short-term municipal rates and investing the proceeds in longer maturity issues that have higher yields. The degree to which the Trust can benefit from its use of leverage may affect its ability to pay high monthly income. At the end of the period, the Trust's leverage amount was 34% of total assets. Municipals outperformed most spread products on a tax-adjusted basis during the period, except on the short-end of the yield curve. The curve steepened over the period and the 20-year to 25-year part of the curve remains very steep on a historical basis. We remain overweight in premium coupon securities in an effort to avoid market discount problems. Premium coupon securities offer better price performance during periods of falling interest rates, and similar performance to discounts when interest rates rise. Retail demand improved at the end of the period, primarily for bonds 15-years or longer.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED) -------------------------------------------------------------------------------- NOTE 1. ORGANIZATION The BlackRock California Investment Quality Municipal & ACCOUNTING Trust Inc. (the "Trust") was organized in Maryland on POLICIES April 12, 1993 as a non-diversified closed-end management investment company. The Trust's investment objective is to manage a portfolio of investment quality securities while providing high current income exempt from regular Federal and California state income taxes consistent with the preservation of capital. The ability of issuers of debt securities held by the Trust to meet their obligations may be affected by economic developments in the state, a specific industry or region. No assurance can be given that the Trust's investment objective will be achieved. The following is a summary of significant accounting policies followed by the Trust. SECURITIES VALUATION: Municipal securities (including commitments to purchase such securities on a "when-issued" basis) are valued on the basis of prices provided by dealers or pricing services approved by the Trust's Board of Directors. In determining the value of a particular security, pricing services may use certain information with respect to transactions in such securities quotations from bond dealers, market transactions in comparable securities and various relationships between securities. Short-term securities are valued at amortized cost. Any securities or other assets for which such current market quotations are not readily available are valued at fair value as determined in good faith under procedures established by and under the general supervision and responsibility of the Trust's Board of Directors. SECURITIES TRANSACTIONS AND INVESTMENT INCOME: Securities transactions are recorded on the trade date. Realized and unrealized gains and losses are calculated on the identified cost basis. Interest income is recorded on the accrual basis and the Trust accretes original issue discount or amortizes premium on securities purchased using the interest method. FEDERAL INCOME TAXES: It is the Trust's intention to continue to meet the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute sufficient net income to shareholders. For this reason and because substantially all of the Trust's gross income consists of tax-exempt interest, no Federal income tax provision is required. DIVIDENDS AND DISTRIBUTIONS: The Trust declares and pays dividends and distributions to common shareholders monthly from net investment income, net realized short-term capital gains and other sources, if necessary. Net long-term capital gains, if any, in excess of loss carryforwards may be distributed annually. Dividends and distributions are recorded on the ex-dividend date. Dividends and distributions to preferred shareholders are accrued and determined as described in Note 4. ESTIMATES: The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. DEFERRED COMPENSATION PLAN: Under a deferred compensation plan approved by the Board of Directors on February 24, 2000, non-interested Directors may elect to defer receipt of all or a portion of their annual compensation. Deferred amounts earn a return as though equivalent dollar amounts had been invested in common shares of other BlackRock funds selected by the Directors. This has the same economic effect as if the Directors had invested the deferred amounts in such other BlackRock funds. The deferred compensation plan is not funded and obligations thereunder represent general unsecured claims against the general assets of the Trust. The Trust may, however, elect to invest in common shares of those funds selected by the Directors in order to match its deferred compensation obligations. NEW ACCOUNTING POLICIES: The Trust 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 Trust will begin amortizing discounts on debt securities effective November 1, 2000. Prior to this date, the Trust amortized premiums and original issue discount on debt securities but did not amortize market discount. The cumulative effect of this accounting change will have no impact on the total net assets of the Trust. The impact of this accounting change is anticipated to have an immaterial effect on the financial statements and will result in an increase to cost of securities and a corresponding decrease in net unrealized appreciation, based on securities held as of October 31, 2000. NOTE 2. AGREEMENTS The Trust has an Investment Advisory Agreement with BlackRock Advisors, Inc., which is a wholly-owned subsidiary of BlackRock, Inc., which in turn is an indirect, majority-owned 10 subsidiary of PNC Financial Services Group, Inc. The Trust has an Administration Agreement with Prudential Investments Fund Management LLC ("PIFM"), an indirect, wholly-owned subsidiary of The Prudential Insurance Company of America. The investment advisory fee paid to the Advisor is computed weekly and payable monthly at an annual rate of 0.35% Of the Trust's average weekly net investment assets. The administration fee paid to PIFM is also computed weekly and payable monthly at an annual rate of 0.10% Of the Trust's average weekly net investment assets. Pursuant to the agreements, the Advisor provides continuous supervision of the investment portfolio and pays the compensation of the officers of the Trust who are affiliated persons of the Advisor. PIFM pays occupancy and certain clerical and accounting costs of the Trust. The Trust bears all other costs and expenses. NOTE 3. PORTFOLIO Sales of investment securities other than short-term SECURITIES investments, for the six months ended April 30, 2001 aggregated $50,000. There were no purchases for the same period. The Federal income tax basis of the Trust's investments at April 30, 2001 was substantially the same as the basis for financial reporting purposes and, accordingly, net and gross unrealized appreciation was $1,714,129. For Federal income tax purposes, the Trust had a capital loss carryforward at October 31, 2000 of approximately $773,000 which will expire in 2002. Accordingly, no capital gain distribution is expected to be paid to shareholders until net gains have been realized in excess of such amount. NOTE 4. CAPITAL There are 200 million shares of $.01 par value common stock authorized. The Trust may classify or reclassify any unissued shares of common stock into one or more series of preferred stock. Of the 1,007,093 common shares outstanding at April 30, 2001, the Advisor owned 7,093 shares. As of April 30, 2001 there were 300 shares of preferred Stock Series W7 outstanding. Dividends on Series W7 are cumulative at a rate which is reset every 7 days based on the results of an auction. Dividend rates ranged from 2.50% to 4.19% during the six months ended April 30, 2001. The Trust may not declare dividends or make other distributions on common shares or purchase any such shares if, at the time of the declaration, distribution, or purchase, asset coverage with respect to the outstanding preferred stock would be less than 200%. The preferred stock is redeemable at the option of the Trust, in whole or in part, on any dividend payment date at $25,000 per share plus any accumulated or unpaid dividends whether or not declared. The preferred stock is also subject to mandatory redemption at $25,000 per share plus any accumulated or unpaid dividends, whether or not declared if certain requirements relating to the composition of the assets and liabilities of the Trust as set forth in the Articles of Incorporation are not satisfied. The holders of preferred stock have voting rights equal to the holders of common stock (one vote per share) and will vote together with holders of shares of common stock as a single class. However, holders of preferred stock are also entitled to elect two of the Trust's directors. In addition, the Investment Company Act of 1940 requires that along with approval by stockholders that might otherwise be required, and the approval of the holders of a majority of any outstanding preferred stock, voting separately as a class would be required to (a) adopt any plan of reorganization that would adversely affect the preferred stock and (b) take any action requiring a vote of security holders, including, among other things, changes in the Trust's subclassification as a closed-end investment company or changes in its fundamental investment restrictions. NOTE 5. DIVIDENDS Subsequent to April 30, 2001, the Board of Directors of the Trust declared a dividend from undistributed earnings of $0.065625 per common share payable June 1, 2001 to shareholders of record on May 15, 2001. For the period May 1, 2001 to May 31, 2001, dividends declared on Preferred Stock totalled $18,974 in aggregate for the outstanding preferred stock. 11 -------------------------------------------------------------------------------- THE BLACKROCK CALIFORNIA INVESTMENT QUALITY MUNICIPAL TRUST INC. DIVIDEND REINVESTMENT PLAN -------------------------------------------------------------------------------- Pursuant to the Trust's Dividend Reinvestment Plan (the "Plan"), common shareholders are automatically enrolled to have all distributions of dividends and capital gains reinvested by State Street Bank and Trust Company (the "Plan Agent") in Trust shares pursuant to the Plan. Shareholders who elect not to participate in the Plan will receive all distributions in cash paid by check in United States dollars mailed directly to the shareholders of record (or if the shares are held in street or other nominee name, then to the nominee) by the transfer agent, as dividend disbursing agent. The Plan Agent serves as agent for the shareholders in administering the Plan. After the Trust declares a dividend or determines to make a capital gain distribution, the Plan Agent will, as agent for the participants, receive the cash payment and use it to buy Trust shares in the open market on the American Stock Exchange or elsewhere for the participants' accounts. The Trust will not issue any new shares under the Plan. Participants in the Plan may withdraw from the Plan upon written notice to the Plan Agent and will receive certificates for whole Trust shares and a cash payment will be made for any fraction of a Trust share. The Plan Agent's fees for the handling of the reinvestment of dividends and distributions will be paid by the Trust. However, each participant will pay a pro rata share of brokerage commissions incurred with respect to the Plan Agent's open market purchases in connection with the reinvestment of dividends and distributions. The automatic reinvestment of dividends and distributions will not relieve participants of any Federal income tax that may be payable on such dividends or distributions. The Trust reserves the right to amend or terminate the Plan as applied to any dividend or distribution paid subsequent to written notice of the change sent to all shareholders of the Trust at least 90 days before the record date for the dividend or distribution. The Plan also may be amended or terminated by the Plan Agent upon at least 90 days' written notice to all shareholders of the Trust. All correspondence concerning the Plan should be directed to the Plan Agent at (800) 699-1BFM. The addresses are on the front of this report. 12 -------------------------------------------------------------------------------- THE BLACKROCK CALIFORNIA INVESTMENT QUALITY MUNICIPAL TRUST INC.

INVESTMENT SUMMARY -------------------------------------------------------------------------------- THE TRUST'S INVESTMENT OBJECTIVE The BlackRock California Investment Quality Municipal Trust's investment objective is to provide high current income exempt from regular Federal and California income tax consistent with the preservation of capital. WHO MANAGES THE TRUST? BlackRock Advisors, Inc. (the "Advisor") manages the Trust. The Advisor is a wholly-owned subsidiary of BlackRock, Inc. ("BlackRock"), which is one of the largest publicly traded investment management firms in the United States with $202 billion of assets under management as of March 31, 2001. BlackRock manages assets on behalf of more than 3,300 institutions and 200,000 individuals worldwide, including nine of the ten largest companies in the U.S. as determined by Fortune Magazine, through a variety of equity, fixed income, liquidity and alternative investment separate accounts and mutual funds, including the BLACKROCK FUNDS and BLACKROCK PROVIDENT INSTITUTIONAL FUNDS. In addition, BlackRock provides risk management and technology services to a growing number of institutional investors under the BLACKROCK SOLUTIONS name. Clients are served from BlackRock's headquarters in New York City, as well as offices in Wilmington, DE, Edinburgh, Scotland, Tokyo, Japan, and Hong Kong. BlackRock is a member of The PNC Financial Services Group, Inc. ("PNC"), one of the largest diversified financial services organizations in the United States, and is majority-owned by PNC and by BlackRock employees. WHAT CAN THE TRUST INVEST IN? Under normal conditions, the Trust expects to continue to manage its assets so that at least 80% of its investments are rated at least investment grade ("BBB"by Standard & Poor's or "Baa" by Moody's Investor Services) and up to 20% of its assets may instead be deemed to be of equivalent credit quality by the Advisor. The Trust intends to invest substantially all of the assets in a portfolio of investment grade California Municipal Obligations, which include debt obligations issued by or on behalf of California, its political subdivisions, agencies and instrumentalities and by other qualifying issuers that pay interest which, in the opinion of the bond counsel of the issuer, is exempt from regular Federal and California income tax. California Municipal Obligations are issued to obtain funds for various public functions, including the construction of public facilities, the refinancing of outstanding obligations, the obtaining of funds for general operating expenses and for loans to other public institutions and facilities. WHAT IS THE ADVISOR'S INVESTMENT STRATEGY? The Advisor will manage the assets of the Trust in accordance with the Trust's investment objective and policies to seek to achieve its objective by investing in investment grade California Municipal Obligations or other qualifying issuers. The Advisor actively manages the assets in relation to market conditions and interest rate changes. Depending on yield and portfolio allocation considerations, the Advisor may choose to invest a portion of the Trust's assets in securities which pay interest that is subject to AMT(alternative minimum tax). The Trust intends to emphasize investments in California municipal obligations with long-term maturities and expects to maintain an average portfolio maturity of 15-20 years, but the average maturity may be shortened or lengthened from time to time depending on market conditions. Under current market conditions the use of leverage increases the income earned by the Trust. The Trust employs leverage primarily through the issuance of preferred stock. Preferred stockholders will receive dividends based on short-term rates in exchange for allowing the Trust to borrow additional assets. These assets will be invested in longer-term assets which typically offer higher interest rates and the difference between the cost of the dividends paid to preferred stockholders and the interest earned on the longer-term securities will provide higher income levels for common stockholders in most interest rate environments. See "Leverage Considerations in the Trust" below. 14 HOW ARE THE TRUST'S SHARES PURCHASED AND SOLD? DOES THE TRUST PAY DIVIDENDS REGULARLY? The Trust's common shares are traded on the American Stock Exchange which provides investors with liquidity on a daily basis. Orders to buy or sell shares of the Trust must be placed through a registered broker or financial advisor. The Trust pays monthly dividends which are typically paid on the first business day of the month. For shares held in the shareholder's name, dividends may be reinvested in additional shares of the Trust through its transfer agent, State Street Bank and Trust Company. Investors who wish to hold shares in a brokerage account should check with their financial advisor to determine whether their brokerage firm offers dividend reinvestment services. LEVERAGE CONSIDERATIONS IN THE TRUST Leverage increases the duration (or price sensitivity of the net assets with respect to changes in interest rates) of the Trust, which can improve the performance of the fund in a declining rate environment, but can cause net assets to decline faster than the market in a rapidly rising interest rate environment. The Trust may reduce, or unwind, the amount of leverage employed should the Advisor consider that reduction to be in the best interests of the Trust. The Advisor's portfolio managers continuously monitor and regularly review the Trust's use of leverage and maintain the ability to unwind the leverage if that course is chosen. SPECIAL CONSIDERATIONS AND RISK FACTORS RELEVANT TO THE TRUST THE TRUST IS INTENDED TO BE A LONG-TERM INVESTMENT AND IS NOT A SHORT-TERM TRADING VEHICLE. INVESTMENT OBJECTIVE. Although the objective of the Trust is to provide high current income exempt from regular Federal and California income tax consistent with the preservation of capital, there can be no assurance that this objective will be achieved. DIVIDEND CONSIDERATIONS. The income and dividends paid by the Trust are likely to vary over time as fixed income market conditions change. Future dividends may be higher or lower than the dividend the Trust is currently paying. LEVERAGE. The Trust utilizes leverage through the issuance of preferred stock, which involves special risks. The Trust's net asset value and market value may be more volatile due to its use of leverage. MARKET PRICE OF SHARES. The shares of closed-end investment companies such as the Trust trade on the American Stock Exchange (AMEX symbol: RAA) and as such are subject to supply and demand influences. As a result, shares may trade at a discount or a premium to their net asset value. INVESTMENT GRADE MUNICIPAL OBLIGATIONS. The value of municipal debt securities generally varies inversely with changes in prevailing market interest rates. Depending on the amount of call protection that the securities in the Trust have, the Trust may be subject to certain reinvestment risks in environments of declining interest rates. ILLIQUID SECURITIES. The Trust may invest in securities that are illiquid, although under current market conditions the Trust expects to do so to only a limited extent. These securities involve special risks. ANTITAKEOVER PROVISIONS. Certain antitakeover provisions will make a change in the Trust's business or management more difficult without the approval of the Trust's Board of Directors and may have the effect of depriving shareholders of an opportunity to sell their shares at a premium above the prevailing market price. 15 -------------------------------------------------------------------------------- THE BLACKROCK CALIFORNIA INVESTMENT QUALITY MUNICIPAL TRUST INC.
