This practice is often called "householding" and it helps eliminate duplicate mailings to shareholders. EATON VANCE, OR YOUR FINANCIAL ADVISER, MAY HOUSEHOLD THE MAILING OF YOUR DOCUMENTS INDEFINITELY UNLESS YOU INSTRUCT EATON VANCE, OR YOUR FINANCIAL ADVISER, OTHERWISE. If you would prefer that your Eaton Vance documents not be householded, please contact Eaton Vance at 1-800-262-1122, or contact your financial adviser.

EATON VANCE INSURED MUNICIPAL BOND FUNDS AS OF MARCH 31, 2003 LETTER TO SHAREHOLDERS [Thomas J. Fetter Photo] Thomas J. Fetter President Amid the dramatic interest rate decline of recent years, many bonds issued at relatively high interest rates from 1993-1998 have been pre-refunded by their issuers. As a result, escrowed bonds have played an increasingly prominent role in municipal bond portfolios. However, while these bonds are valued by professional investors, analysts and portfolio managers, many individual investors have little knowledge of why bonds are escrowed. As part of our continuing educational series, we thought it might be helpful to discuss the mechanics of escrowed bonds and the role of those bonds in the municipal market. The process of escrowing municipal bonds to maturity... In the escrowing process, an issuing jurisdiction essentially refinances original-issue debt with newer, usually lower-interest debt. The jurisdiction issues a "refunding bond," the proceeds of which are used to purchase specially-issued U.S. Treasury bonds - State and Local Government Series bonds, which are held in an irrevocable escrow account by a trustee bank. The principal and interest payments of these Treasury bonds exactly match the future principal and interest payments of the issuer's original bonds. The principal and interest from these U.S. Treasuries are directed solely to pay the interest and principal on the tax-exempt bonds for which the escrow account was established. Thus, the original bonds are now backed by U.S. Treasuries and are, therefore, deemed among the highest quality of all tax-exempt issues. Benefits for issuers: lower interest rates and added flexibility... When municipal bonds are escrowed, they are said to be "defeased." That means that the bonds are no longer governed by the original covenants and are no longer a direct obligation of the original issuer. The most common defeasance - "high-to-low" defeasance - is based on an economic rationale, in which an issuer seeks to take advantage of a significant decline in interest rates - much the same way homeowners refinance their mortgages. By refunding high-coupon bonds with lower-coupon debt, issuers are able to reduce their interest expenses and save taxpayers and ratepayers money. A second, less common procedure is "low-to-high" defeasance - in which relatively low-coupon bonds are refunded with higher-coupon bonds. This refunding is generally based on a pressing political or structural need, done primarily to effect a change in bond covenants. This change may provide more flexibility for issuers by broadening a project's mandate or redefining revenue sources. Benefits for investors: higher quality, shorter maturities, attractive coupons... For investors, owning a bond that has been escrowed generally provides an immediate upgrade in quality - and often in price - because the bond is now backed by U.S. Treasuries. In addition, because these bonds are typically called at their earliest call date, they will have a shorter effective maturity and, therefore, less volatility. Finally, in most cases, the bond continues to pay an above-average coupon. These characteristics can represent distinct advantages for investors. However compelling these benefits are, a portfolio manager still faces a key decision: whether to hold the bond with its attractive coupon and no credit risk - or - to sell the bond at its increased market value and redeploy the increased purchasing power at current interest rates. The portfolio manager must factor in market conditions, the interest rate outlook, the availability of bonds in the marketplace and call provisions. If the escrowed bond's original call provisions have been waived, that will dramatically improve the bond's trading characteristics. These decisions can have a profound effect upon performance. Moreover, the treatment of escrowed bonds is yet another area that demonstrates the value of professional management. We believe that familiarity with bond covenants, trading patterns and in-depth analysis can provide investors a major advantage in municipal bond investing. Sincerely, /s/ Thomas J. Fetter Thomas J.

Waning consumer confidence and reduced capital spending resulted in weak demand for goods and services, a condition aggravated by the prolonged decline in the equity markets. Consumer spending, which had held up surprisingly well through much of 2002, slowed significantly by year end. For their part, businesses were loathe to commit new capital investment in an uncertain economy. These trends contributed to rising unemployment and increased volatility in the financial markets. Helped by low interest rates and sales incentives, the auto and housing markets kept the U.S. economy afloat... While economic activity remained sluggish, there were some bright spots that kept the economy afloat. Together with manufacturers' incentives, record-low interest rates encouraged car buyers. Similarly, low mortgage rates kept the housing market alive, although the torrid sales pace of recent years has cooled considerably. By year-end, however, amid rising consumer debt and an increasing jobless rate, there were signs that U.S. consumers were adopting more conservative spending habits. The Federal Reserve again lowered short-term interest rates in November... After rising a feeble 1.4% in the fourth quarter of 2002, the nation's Gross Domestic Product expanded 1.6% in the first quarter of 2003, according to preliminary figures. The nation's unemployment rate moved higher, as a clouded outlook prompted businesses to reduce payrolls. Meanwhile, business investment in new technology - which generates innovation, improves productivity and is often viewed as a key to recovery - was generally deferred until business owners can see beyond the current uncertainties. Against this backdrop, the Federal Reserve, which had held rates steady through most of the year, saw danger of a further retrenchment in November and reduced the Federal Funds rate - a key short-term interest rate barometer - to 1.25%, a 40-year low. The bond markets - whose prices move in the opposite direction of interest rates - rallied in response to that action. Ten-year Treasury bond yields, which were as high as 5.40% in March 2002 - declined to 3.80% by March 31, 2003, as the economic recovery failed to materialize. Facing revenue shortfalls, many states are consid- ering tax increases... We continue to believe that municipal bonds merit a place in a diversified investment portfolio. Amid the uncertain economic outlook, we believe the prospect of a dramatic increase in interest rates remains remote. In addition, with states reporting revenue shortfalls as a result of the weak economy, many are faced with looming budget deficits. Because the overwhelming majority are legally obligated to balance their budgets, legislatures are faced with the unpleasant prospect of raising state taxes to achieve a balanced ledger. The potential for higher state taxes could make municipal bonds even more compelling for tax-conscious investors.

Fetter Photo] Thomas J. Fetter Portfolio Manager MANAGEMENT UPDATE - The U.S. economy remained subdued in late 2002 and early 2003. Political and economic uncertainties constrained consumer and business spending and tempered near-term expectations for growth. The nation's jobless rate was 5.8% in March 2003, up from 5.7% a year ago. - Insured* transportation bonds constituted the Fund's largest sector weighting at March 31, 2003. The Fund's investments were well diversified across the nation and spanned a broad range of projects, including turnpikes, an airport authority, and mass transit. - Insured* water and sewer bonds remained a significant focus of the Fund. Because utilities and other essential services bonds are backed by user fees, they tend to have more stable revenues than bonds backed by more discretionary expenditures. - Insured* general obligations (GOs) were a major investment for the Fund. Given the budgetary problems facing many state and local governments, insured* GOs represented a source of quality and good liquidity. - In its initial months of operation, the Fund has emphasized the importance of call protection. Given the sharp decline in interest rates, bonds with approaching call dates tend to have less favorable performance characteristics.

Clemson Photo] Cynthia J. Clemson Portfolio Manager MANAGEMENT UPDATE - The California economic recovery stalled in 2002, amid a significant fall-off in consumer spending. The state suffered job losses in information technology, the service sector and manufacturing, as employers responded to weaker orders with layoffs. The state's March 2003 jobless rate was 6.6%, unchanged from a year ago. - Insured* general obligations (GOs) constituted a large Fund investment. In an uncertain economic environment, many states and municipalities have experienced an uncertain revenue outlook. Therefore, insured GOs represented a dependable revenue stream as well as an added element of quality. - Insured* transportation bonds constituted a sizable portion of the Fund and represented quality issuers. These bonds financed major projects needed to upgrade major transportation infrastructure, including airport, highway and mass transit projects. - Insured* water and sewer bonds have played a prominent role in the Fund. These issues are often sought by investors in a slow economy because they finance an essential service and are less vulnerable to cutbacks in consumer spending. - With the dramatic decline in interest rates increasing call risk, management emphasized non-callable bonds and bonds with favorable call characteristics. The calling of older, higher-coupon bonds has made call protection an important consideration for investors.

Fetter Photo] Thomas J. Fetter Portfolio Manager MANAGEMENT UPDATE - The New York economy has yet to regain its pre-September 11 level of employment. The key financial services sector remained under pressure, as the equity markets experienced continued volatility and underwriting was below the pace of previous years. The state's March 2003 jobless rate was 6.1%, up from 6.0% a year ago. - Insured* transportation bonds represented the Fund's largest sector weighting at March 31, 2003. Investments included bonds for tunnel and bridge authorities, thruways and port facilities, which are among New York State's most frequent and well-regarded issuers. - The Fund had large investments in insured* education bonds. These issues, which financed the construction of classroom and dormitories for colleges and universities throughout the state are typically less vulnerable to an economic slowdown than cyclical bonds. - Insured* hospital bonds constituted a major focus for the Fund. In the competitive New York hospital sector, the Fund emphasized institutions with sound financial structures, good management and highly marketable specialities. - The Fund has made diversification a primary goal in its first months of operation. Management also established good call protection in order to protect against untimely calls and improve the Fund's performance potential.

SEE NOTES TO FINANCIAL STATEMENTS 24 EATON VANCE INSURED MUNICIPAL BOND FUNDS AS OF MARCH 31, 2003 NOTES TO FINANCIAL STATEMENTS (UNAUDITED) 1 Significant Accounting Policies ------------------------------------------- Eaton Vance Insured Municipal Bond Fund (Insured Municipal Fund), Eaton Vance Insured California Municipal Bond Fund (Insured California Fund), and Eaton Vance Insured New York Municipal Bond Fund (Insured New York Fund), (individually referred to as the Fund or collectively the Funds) are registered under the Investment Company Act of 1940, as amended, as non- diversified, closed-end management investment companies. The Insured Municipal Fund was organized under the laws of the Commonwealth of Massachusetts by an Agreement and Declaration of Trust dated July 2, 2002. The Insured California Fund and the Insured New York Fund were organized under the laws of the Commonwealth of Massachusetts by an Agreement and Declaration of Trust dated July 8, 2002. Each Fund's investment objective is to achieve current income exempt from regular federal income tax, including alternative minimum tax, and taxes in its specified state. Each Fund seeks to achieve its objective by investing primarily in high grade municipal obligations that are insured as to the timely payment of principal and interest. The following is a summary of significant accounting policies consistently followed by each Fund in the preparation of its financial statements. The policies are in conformity with accounting principles generally accepted in the United States of America. A Investment Valuation -- Municipal bonds are normally valued on the basis of valuations furnished by a pricing service. Futures contracts listed on the commodity exchanges are valued at closing settlement prices. Interest rate swaps are normally valued on the basis of valuations furnished by a broker. Short-term obligations, maturing in sixty days or less, are valued at amortized cost, which approximates fair value. Investments for which valuations or market quotations are unavailable are valued at fair value using methods determined in good faith by or at the direction of the Trustees. B Investment Transactions -- Investment transactions are recorded on a trade date basis. Realized gains and losses from such transactions are determined using the specific identification method. Securities purchased or sold on a when-issued or delayed delivery basis may be settled a month or more after the transaction date. The securities so purchased are subject to market fluctuations during this period. To the extent that when-issued or delayed delivery purchases are outstanding, the Fund instructs the custodian to segregate assets in a separate account, with a current value at least equal to the amount of its purchase commitments. C Income -- Interest income is determined on the basis of interest accrued, adjusted for amortization of premium or discount. D Federal Taxes -- Each Fund's policy is to comply with the provisions of the Internal Revenue Code applicable to regulated investment companies and to distribute to shareholders each year all of its taxable, if any, and tax-exempt income, including any net realized gain on investments. Therefore, no provision for federal income or excise tax is necessary. At September 30, 2002, the Insured New York Fund, for federal income tax purposes, had a capital loss carryover of $9,464 which will reduce the taxable income arising from future net realized gain on investments, if any, to the extent permitted by the Internal Revenue Code and thus will reduce the amount of distributions to shareholders which would otherwise be necessary to relieve the Fund of any liability for federal income or excise tax. Such capital loss carryover will expire on September 30, 2010. In addition, each Fund intends to satisfy conditions which will enable it to designate distributions from the interest income generated by its investments in municipal obligations, which are exempt from regular federal income taxes when received by each Fund, as exempt-interest dividends. E Offering Costs -- Costs incurred by the Funds in connection with the offerings of the common shares and preferred shares were recorded as a reduction of capital paid in excess of par applicable to common shares. F Financial Futures Contracts -- Upon the entering of a financial futures contract, a Fund is required to deposit (initial margin) either in cash or securities an amount equal to a certain percentage of the purchase price indicated in the financial futures contract. Subsequent payments are made or received by a Fund (margin maintenance) each day, dependent on the daily fluctuations in the value of the underlying security, and are recorded for book purposes as unrealized gains or losses by a Fund. A Fund's investment in financial futures contracts is designed for both hedging against anticipated future changes in interest rates and investment purposes. Should interest rates move unexpectedly, a Fund may not achieve the anticipated benefits of the financial futures contracts and may realize a loss. G Interest Rate Swaps -- The Funds may enter into interest rate swap agreements to enhance return, to hedge against fluctuations in securities prices or interest rates or as substitution for the purchase and sale of securities. Pursuant to these agreements, the Funds make bi-annual payments at a fixed interest rate. In exchange, the Funds 25 EATON VANCE INSURED MUNICIPAL BOND FUNDS AS OF MARCH 31, 2003 NOTES TO FINANCIAL STATEMENTS (UNAUDITED) CONT'D receive payments based on the interest rate of a benchmark industry index. During the term of the outstanding swap agreement, changes in the underlying value of the swap are recorded as unrealized gains and losses. The value of the swap is determined by changes in the relationship between two rates of interest. The Funds are exposed to credit loss in the event of non-performance by the swap counterparty. However, the Funds do not anticipate non-performance by the counterparty. Risk may also arise from the unanticipated movements in value of interest rates. H 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 at the date of the financial statements and the reported amounts of income and expense during the reporting period. Actual results could differ from those estimates. I Expense Reduction -- Investors Bank & Trust Company (IBT) serves as custodian of the Funds. Pursuant to the respective custodian agreements, IBT receives a fee reduced by credits which are determined based on the average daily cash balances each Fund maintains with IBT. All significant credit balances used to reduce the Funds' custodian fees are reported as a reduction of total expenses in the Statement of Operations. J Interim Financial Statements -- The interim financial statements relating to March 31, 2003 and for the six months then ended have not been audited by independent certified public accountants, but in the opinion of the Funds' management reflect all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of the financial statements. 2 Auction Preferred Shares (APS) ------------------------------------------- Each Fund issued Auction Preferred Shares on October 29, 2002 in a public offering. The underwriting discounts and other offering costs were recorded as a reduction of the capital of the common shares of each Fund. Dividends on the APS, which accrue daily, are cumulative at a rate which was established at the offering of each Fund's APS and have been reset every seven days thereafter by an auction. Effective March 4, 2003, a special dividend period of 364 days was set on the Series B shares of the Insured Municipal Fund. The dividend rate, which matures on March 2, 2004 is 1.18%. Auction Preferred Shares issued and outstanding as of March 31, 2003 and dividend rate ranges for the six months ended March 31, 2003 are as indicated below: PREFERRED SHARES DIVIDEND RATE FUND ISSUED AND OUTSTANDING RANGES -------------------------------------------------------------------------------- Insured Municipal Fund Series A 4,740 0.90% - 1.60% Insured Municipal Fund Series B 4,740 0.90% - 1.55% Insured Municipal Fund Series C 4,740 0.85% - 1.55% Insured Municipal Fund Series D 4,740 0.95% - 1.55% Insured Municipal Fund Series E 4,740 0.94% - 1.55% Insured California Fund Series A 3,900 0.85% - 1.45% Insured California Fund Series B 3,900 0.89% - 1.45% Insured New York Fund Series A 2,850 0.89% - 1.65% Insured New York Fund Series B 2,850 0.95% - 1.60% The APS are redeemable at the option of each Fund at a redemption price equal to $25,000 per share, plus accumulated and unpaid dividends on any dividend payment date. The APS are also subject to mandatory redemption at a redemption price equal to $25,000 per share, plus accumulated and unpaid dividends, if any Fund is in default for an extended period on its asset maintenance requirements with respect to the APS. If the dividends on the APS shall remain unpaid in an amount equal to two full years' dividends, the holders of the APS as a class have the right to elect a majority of the Board of Trustees. In general, the holders of the APS and the Common Shares have equal voting rights of one vote per share, except that the holders of the APS, as a separate class, have the right to elect at least two members of the Board of Trustees. The APS have a liquidation preference of $25,000 per share, plus accumulated and unpaid dividends. Each Fund is required to maintain certain asset coverage with respect to the APS as defined in each Fund's By-Laws and the Investment Company Act of 1940. Each Fund pays an annual fee equivalent to 0.25% of the preferred shares liquidation value for the remarketing efforts associated with the preferred auction. 3 Distributions to Shareholders ------------------------------------------- Each Fund intends to make monthly distributions of net investment income, after payments of any dividends on any outstanding Auction Preferred Shares. Distributions are recorded on the ex-dividend date. Distributions to preferred shareholders are recorded daily and are payable at the end of each dividend period. Each dividend payment period for the Auction Preferred Shares is generally seven days. Effective March 4, 2003, the Series B shares set a special dividend period of 364 days. The applicable 26 EATON VANCE INSURED MUNICIPAL BOND FUNDS AS OF MARCH 31, 2003 NOTES TO FINANCIAL STATEMENTS (UNAUDITED) CONT'D dividend rate for Auction Preferred Shares on March 31, 2003 are listed below. For the six months ended March 31, 2003, the amount of dividends each Fund paid to Auction Preferred shareholders and average APS dividend rates for such period were as follows: DIVIDENDS PAID TO AVERAGE APS APS PREFERRED SHAREHOLDERS DIVIDEND RATES DIVIDEND RATES FOR THE SIX MONTHS FOR THE SIX MONTHS AS OF ENDED ENDED FUND MARCH 31, 2003 MARCH 31, 2003 MARCH 31, 2003 ---------------------------------------------------------------------------------------------------- Insured Municipal Fund Series A 0.90% $568,705 1.16% Insured Municipal Fund Series B 1.18% 573,744 1.18% Insured Municipal Fund Series C 0.95% 550,873 1.12% Insured Municipal Fund Series D 0.95% 571,669 1.17% Insured Municipal Fund Series E 1.00% 568,882 1.15% Insured California Fund Series A 0.90% 420,902 1.02% Insured California Fund Series B 0.95% 432,853 1.06% Insured New York Fund Series A 0.89% 349,096 1.17% Insured New York Fund Series B 1.00% 348,882 1.16% The Funds distinguish between distributions on a tax basis and a financial reporting basis. Accounting principles generally accepted in the United States of America require that only distributions in excess of tax basis earnings and profits be reported in the financial statements as a return of capital. Permanent differences between book and tax accounting relating to distributions are reclassified to paid in capital. These differences relate primarily to the method for amortizing premiums. 4 Investment Adviser Fee and Other Transactions with Affiliates ------------------------------------------- The investment adviser fee, computed at an annual rate of 0.65% of each Fund's average weekly gross assets, was earned by Eaton Vance Management (EVM) as compensation for investment advisory services rendered to each Fund. Except for Trustees of each Fund who are not members of EVM's organization, officers and Trustees receive remuneration for their services to each Fund out of such investment adviser fee. For the six months ended March 31, 2003, the fee was equivalent to 0.65% (annualized) of each Fund's average weekly gross assets and amounted to $4,568,203, $1,504,492, and $1,103,445 for Insured Municipal Fund, Insured California Fund and Insured New York Fund, respectively.

These financial instruments include futures contracts and may involve, to a varying degree, elements of risk in excess of the amounts recognized for financial statement purposes. The notional or contractual amounts of these instruments represent the investment each Fund has in particular classes of financial instruments and does not necessarily represent the amounts potentially subject to risk. The measurement of the risks associated with these instruments is meaningful only when all related and offsetting transactions are considered. A summary of obligations under these financial instruments at March 31, 2003 is as follows: FUTURES CONTRACTS ------------------------------------------------------------------------------------------------ NET UNREALIZED EXPIRATION APPRECIATION FUND DATE CONTRACTS POSITION (DEPRECIATION) ------------------------------------------------------------------------------------------------ Insured Municipal 6/03 764 U.S. Treasury Bond Short $(649,018) ------------------------------------------------------------------------------------------------ Insured California 6/03 300 U.S. Treasury Bond Short $ 431,949 ------------------------------------------------------------------------------------------------ Insured New York 6/03 183 U.S. Treasury Bond Short $(155,458) At March 31, 2003, each Fund had sufficient cash and/or securities to cover margin requirements on open futures contracts. 28 EATON VANCE INSURED MUNICIPAL BOND FUNDS Dividend Reinvestment Plan Each Fund offers a dividend reinvestment plan (the Plan) pursuant to which shareholders may elect to have dividends and capital gains distributions automatically reinvested in common shares (the Shares) of the same Fund. You may elect to participate in the Plan by completing the Dividend Reinvestment Plan Application Form. If you do not participate, you will receive all distributions in cash paid by check mailed directly to you by PFPC Inc. as dividend paying agent. On the distribution payment date, if the net asset value per Share is equal to or less than the market price per Share plus estimated brokerage commissions, then new Shares will be issued. The number of Shares shall be determined by the greater of the net asset value per Share or 95% of the market price. Otherwise, Shares generally will be purchased on the open market by the Plan Agent. Distributions subject to income tax (if any) are taxable whether or not shares are reinvested. If your shares are in the name of a brokerage firm, bank, or other nominee, you can ask the firm or nominee to participate in the Plan on your behalf. If the nominee does not offer the Plan, you will need to request that your shares be re-registered in your name with each Fund's transfer agent, PFPC Inc., or you will not be able to participate. The Plan Agent's service fee for handling distributions will be paid by each Fund. Each participant will be charged their pro rata share of brokerage commissions on all open-market purchases. Plan participants may withdraw from the Plan at any time by writing to the Plan Agent at the address noted on the following page. If you withdraw, you will receive shares in your name for all Shares credited to your account under the Plan. If a participant elects by written notice to the Plan Agent to have the Plan Agent sell part or all of his or her Shares and remit the proceeds, the Plan Agent is authorized to deduct a $5.00 fee plus brokerage commissions from the proceeds. If you wish to participate in the Plan and your shares are held in your own name, you may complete the form on the following page and deliver it to the Plan Agent. Any inquiries regarding the Plan can be directed to the Plan Agent, PFPC Inc., at 1-800-331-1710. 29 EATON VANCE INSURED MUNICIPAL BOND FUNDS Application for Participation in Dividend Reinvestment Plan This form is for shareholders who hold their common shares in their own names. If your common shares are held in the name of a brokerage firm, bank, or other nominee, you should contact your nominee to see if it will participate in the Plan on your behalf. If you wish to participate in the Plan, but your brokerage firm, bank, or nominee is unable to participate on your behalf, you should request that your common shares be re-registered in your own name which will enable your participation in the Plan.
