Since the Fund began trading on August 27, 2003, the fixed income markets have continued to be volatile. During the Fund's first fiscal year, the 10-Year U.S. Treasury Bond recorded a low yield of 3.681% and rose as high as 4.878% in June 2004 before falling back to a yield of 4.481% on July 30, 2004. The Federal Reserve Board increased the interest rate on Federal Funds 1/4 of a point at its June 2004 meeting, with the stated intent to make additional increases in the future. Oil prices increased steadily to a price of over $43 per barrel on July 30, 2004 and U.S. economic indicators often gave conflicting signals as to where, and how fast, the economy was heading. Amid all the tumult, we continue to believe that investment grade municipal bonds will represent a prudent investment in the fixed income sector. Further, the Fund was and continues to be structured using a hedging strategy to manage duration and to attempt to minimize volatility as rates trend higher. By utilizing both short term and longer term hedges, we have attempted to be prepared if rates were to rise quickly or more slowly over a longer period of time. With the Fund's continued emphasis on long-term value, managed duration and hedging strategies, the Fund's NAV Total Return (calculated on the basis of a beginning per share value of $14.30 - which represents the beginning NAV per share of $14.33 less the $0.03 per share of offering costs - and a closing NAV per share of $13.83, plus the reinvestment of dividends of $0.63 per share) was 1.11% for the period ended July 31, 2004. The Fund's market value total return for the period ended July 31, 2004 based upon an initial offering price of $15.00 per share and a closing market value of $13.11 per share was (8.62)% assuming reinvestment of distributions in shares of the Fund. The Fund's current yield as of July 31, 2004, based on the closing market price of $13.11, was 6.41%. The Fund's tax-equivalent yield as of July 31, 2004 (assuming the maximum federal tax rate of 35%) as 9.86%. Despite the uncertain picture over the coming months, we continue to believe in our strategy, especially given the Federal Reserve Board's aforementioned intent to continue a "measured" rise in short-term rates. The Fund will continue to seek out value in the investment grade municipal sector, focusing on those bonds which we believe will be long-term outperformers. Sincerely, /S/CLIFFORD D. CORSO Clifford D. Corso President, Chief Executive Officer August 20, 2004 PAST PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. There is no guarantee that the Fund's or any other investment technique will be effective under all market conditions. - -------------------------------------------------------------------------------- 1 MBIA Capital/Claymore Managed Duration Investment Grade Municipal Fund Fund Summary (Unaudited) JULY 31, 2004 - -------------------------------------------------------------------------------- FUND INFORMATION - -------------------------------------------------------------------------------- Symbol on New York Stock Exchange: MZF Initial Offering Date: August 27, 2003 Closing Market Price as of 7/31/04: $13.11 Net Asset Value as of 7/31/04: $13.83 Yield on Closing Market Price as of 7/31/04: 6.41% Current Monthly Distribution Per Common Share1: $0.07 Current Annual Distribution Per Common Share1: $0.84 Leverage as of 7/31/042 39% 1 The distribution is not constant and is subject to change. 2 As a percentage of managed assets.

The Fund is registered as a diversified, closed-end management investment company under the Investment Company Act of 1940, as amended. The Fund's investment objective is to provide its common shareholders with high current income exempt from regular Federal income tax while seeking to protect the value of the Fund's assets during periods of interest rate volatility. Prior to commencing operations on August 27, 2003, the Fund had no operations other than matters relating to its organization and registration and the sale and issuance of 6,981 common shares of beneficial interest to MBIA Capital Management Corp. The following is a summary of significant accounting policies followed by the Fund. SECURITIES VALUATION: The municipal bonds in which the Fund invests are traded primarily in the over-the-counter markets. In determining net asset value, the Fund uses the valuations of portfolio securities furnished by a pricing service approved by the Board of Trustees. The pricing service typically values portfolio securities at the bid price or the yield equivalent when quotations are readily available. Municipal bonds for which quotations are not readily available are valued at fair market value on a consistent basis as determined by the pricing service using a matrix system to determine 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 Trustees. Positions in futures contracts, interest rate swaps and options on interest rate swaps ("swaptions") are valued at closing prices for such contracts established by the exchange or dealer market on which they are traded, or if market quotations are not readily available, are valued at fair value on a consistent basis using methods approved in good faith by the Board of Trustees. SECURITIES TRANSACTIONS AND INVESTMENT INCOME: Investment transactions are accounted for on the trade date. Realized gains and losses on investments are determined on the identified cost basis. Interest income and expenses are accrued daily. All discounts/premiums are accreted/amortized for financial reporting purposes as required. SWAPTIONS: The Fund may engage in options transactions on interest rate swap agreements, commonly referred to as swaptions. A swaption is an agreement between two parties where one party purchases the right from the other party - -------------------------------------------------------------------------------- 14 MBIA Capital/Claymore Managed Duration Investment Grade Municipal Fund Notes to Financial Statements JULY 31, 2004 -- CONTINUED to enter into an interest rate swap at a specified date and for a specified "fixed rate" yield (or "exercise" yield). In a pay-fixed swaption, the holder of the swaption has the right to enter into an interest rate swap as a payer of fixed rate interest and receiver of variable rate interest, while the writer of the swaption has the obligation to enter into the other side of the interest rate swap. In a receive-fixed swaption, the holder of the swaption has the right to enter into an interest rate swap as a receiver of fixed rate interest and a payer of variable rate interest, while the writer has the obligation to enter into the opposite side of the interest rate swap. The Fund will enter into such transactions to attempt to hedge some or all of its interest rate exposure in its holdings of municipal bonds. During the period ended July 31, 2004, the Fund purchased pay-fixed swaptions. Upon the purchase of these pay-fixed swaptions by the Fund, the total purchase price paid was recorded as an investment. The market valuation is determined as set forth in the preceding securities valuation paragraph. If the pay-fixed swaptions are exercised, the Fund has the right to enter into an interest rate swap as a payer of fixed rate interest and receiver of variable rate interest. When the pay-fixed swaptions reach their scheduled expiration dates, the Fund will record a gain or loss depending on the difference between the purchase price and the value of the swaptions on their exercise date. During the period ended July 31, 2004, the Fund did not exercise any of the swaptions it had purchased. FEDERAL INCOME TAXES: It is the Fund's intention to elect to be treated as a regulated investment company under the Internal Revenue Code of 1986, as amended, and to distribute sufficient net income to shareholders to qualify as such. For this reason and because substantially all of the Fund's gross income consists of tax-exempt interest, no Federal income tax provision is required. DIVIDENDS AND DISTRIBUTIONS: The Fund intends to declare and pay dividends from net investment income monthly to common shareholders. Distributions of net realized capital gains, if any, will be paid at least annually. Dividends and distributions to shareholders will be recorded on the ex-dividend date. Dividends and distributions to preferred shareholders are accrued and determined as described in Note 5. USE OF 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. - -------------------------------------------------------------------------------- 15 www.mbiaclaymore.com MBIA Capital/Claymore Managed Duration Investment Grade Municipal Fund Notes to Financial Statements JULY 31, 2004 -- CONTINUED NOTE 2 -- AGREEMENTS: - -------------------------------------------------------------------------------- Pursuant to an Investment Advisory Agreement (the "Advisory Agreement") between MBIA Capital Management Corp.

Shareholders whose shares are held in the name of a broker or nominee should contact such broker or nominee to confirm that they are eligible to participate in the Plan. Shareholders who are ineligible or who elect not to participate in the Plan will receive all dividends and distributions in cash paid by check mailed directly to the shareholder of record (or, if the shares are held in street or other nominee name, then to such nominee) by BONY, as dividend paying agent. Such shareholders may elect not to participate in the Plan and to receive all distributions of dividends and capital gains in cash by sending written instructions to BONY, as dividend paying agent, at the address set forth below or by contacting their broker if their shares are held in street name. Participation in the Plan is completely voluntary and may be terminated or resumed at any time without penalty by written notice if received by the Plan Agent not less than ten days prior to any dividend record date; otherwise, such termination will be effective with respect to any subsequently declared dividend or capital gains distribution. Whenever the Fund declares an ordinary income dividend or a capital gain dividend (collectively referred to as "dividends") payable in cash, non-participants in the Plan will receive cash, and participants in the Plan will receive the equivalent in common shares. The shares are acquired by the Plan Agent for the participant's account, depending upon the circumstances described below, either (i) through receipt of additional unissued but authorized common shares from the Fund ("newly issued shares") or (ii) by purchase of outstanding common shares on the open market ("open-market purchases") on the NYSE or elsewhere. If, on the dividend payment date, the market price per common share plus estimated brokerage commissions is greater than the net asset value per common share (such condition being referred to herein as "market premium"), the Plan Agent will invest the dividend amount in newly issued shares on behalf of the participant. The number of newly issued common shares to be credited to the participant's account will be determined by dividing the dollar amount of the dividend by the net asset value per share on the payment date, provided that, if the net asset value per share is less than or equal to 95% of the market price per share on the payment date, the dollar amount of the dividend will be divided by 95% of the market price per share on the payment date. If on the dividend payment date the net asset value per share is greater than the market value plus estimated brokerage commissions (such condition being referred to herein as "market discount"), the Plan Agent will invest the dividend amount in shares acquired on behalf of the participant in open-market purchases. - -------------------------------------------------------------------------------- 24 MBIA Capital/Claymore Managed Duration Investment Grade Municipal Fund Dividend Reinvestment Plan (Unaudited) -- continued If, before the Plan Agent has completed its open-market purchases, the market price of the common shares exceeds the net asset value per share, the average per share purchase price paid by the Plan Agent may exceed the net asset value of the Fund's shares, resulting in the acquisition of fewer shares than if the dividend had been paid in newly issued shares on the dividend payment date. Because of the foregoing difficulty with respect to open-market purchases, the Plan provides that if the Plan Agent is unable to invest the full dividend amount in open-market purchases during the purchase period or if the market discount shifts to a market premium during the purchase period, the Plan Agent may cease making open-market purchases and may invest the uninvested portion of the dividend amount in newly issued shares at the net asset value per share at the close of business on the last purchase date; provided that, if the net asset value per share is less than 95% of the market price per share on the payment date, the dollar amount of the dividend will be divided by 95% of the market price per share on the payment date. The Plan Agent maintains all shareholders' accounts in the Plan and furnishes written confirmation of all transactions in the account, including information needed by shareholders for tax records. Shares in the account of each Plan participant will be held by the Plan Agent in the name of the participant, and each shareholder's proxy will include those shares purchased or received pursuant to the Plan. The Plan Agent will forward all proxy solicitation materials to participants and vote proxies for shares held pursuant to the Plan in accordance with the instructions of the participants. There will be no brokerage charges with respect to shares issued directly by the Fund as a result of dividends or capital gains distributions payable either in shares or in cash. 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. The automatic reinvestment of dividends and distributions will not relieve participants of any Federal, state or local income tax that may be payable (or required to be withheld) on such dividends. The Fund reserves the right to amend or terminate the Plan. There is no direct service charge to participants in the Plan; however, the Fund reserves the right to amend the Plan to include a service charge payable by the participants. All questions and correspondence concerning the Plan should be directed to the Plan Agent at The Bank of New York, 111 Sanders Creek Parkway, East Syracuse, NY 13057 or by phone at 800-701-8178. - -------------------------------------------------------------------------------- 25 www.mbiaclaymore.com MBIA Capital/Claymore Managed Duration Investment Grade Municipal Fund Tax Information (Unaudited) Subchapter M of the Internal Revenue Code of 1986, as amended, requires the Fund to advise shareholders within 60 days of the Funds' tax year end (July 31, 2004) as to the federal tax status of dividends and distributions received by shareholders during such tax period. Accordingly, please note that substantially all dividends paid from net investment income from the Fund during the tax period ended July 31, 2004 were federally exempt interest dividends. The Fund has invested in municipal bonds containing market discount, whose accretion is taxable and accordingly 0.01% of the dividends paid from net investment income during the tax period are attributable to this taxable income. Since the Fund's fiscal year is not the calendar year, another notification will be sent with respect to calendar year 2004. In January 2005, you will be advised on IRS Form 1099 DIV as to the federal tax status of the dividends and distributions received during calendar year 2004. The amount that will be reported will be the amount to use on your 2004 federal income tax return and may differ from the amount which must be reported in connection with the Fund's tax year ended July 31, 2004. Shareholders are advised to consult with their tax advisers as to the federal, state and local tax status of the income received from the Funds. In January 2005, an allocation of interest by state will be provided which may be of value in reducing a shareholder's state or local tax liability, if any. Notice to Shareholders (Unaudited) Notice is hereby given in accordance with Section 23(c) of the Investment Company Act of 1940, as amended, that from time to time the Fund may purchase, at market prices, shares of its common stock in the open market. - -------------------------------------------------------------------------------- 26 MBIA Capital/Claymore Managed Duration Investment Grade Municipal Fund Privacy Policy The privacy of your personal financial information is extremely important to us.
