FETTER] Thomas J. Fetter President In our shareholder reports, we refer frequently to "quality spreads" and their important role in bond analysis. However, while followed closely by bond analysts and portfolio managers, this aspect of municipal bond investing is generally overlooked by individual investors. As part of our continuing educational series, we thought it might be instructive to discuss quality spreads and why they constitute a key variable for investors in the municipal bond market. QUALITY SPREADS: COMPENSATION FOR ADDED CREDIT RISK... The term "quality spread" refers to the difference in yields between bonds of varying quality but similar maturities. A bond rated BBB, for example, should have a higher yield than an insured bond rated AAA because investors who buy lower-quality bonds anticipate being paid for accepting a higher level of credit risk. That risk premium comes in the form of higher yields. Spreads are typically stated in basis points, or 1/100's of a percentage point. Thus, a bond yielding 5.00% trades at a spread of 100 basis points (1.00%) over a bond that yields 4.00%. SPREAD FLUCTUATIONS ARE INFLUENCED BY A VARIETY OF FACTORS... Spreads fluctuate with changes in market conditions, with many factors influencing spread relationships. The quality and type of bond are primary factors. For example, an insured general obligation rated AAA - with no credit risk - will trade at a significantly lower yield than a BBB-rated industrial bond, which has a significantly higher credit risk. Naturally, a bond's price will respond to changes that may impact - for better or worse - the underlying fundamentals of an issuer. Remember, bond yields move in the opposite direction of bond prices. Another factor that influences spreads is supply. Assuming stable demand, spreads are likely to widen if the supply for a specific issuer increases, as the market must now digest a larger volume of bonds. Similarly, if supply declines, spreads may narrow, as investors may be willing to pay more for a credit that is increasingly scarce. Finally, quality spreads may fluctuate with changes in the overall economy. For example, spreads tend to narrow as the economy strengthens and the revenue outlook improves. On the other hand, as the economy slows or enters recession, spreads tend to widen, as investors become increasingly worried about the direction of the economy and its impact on bonds with higher credit risk. SPREADS CONSTITUTE A KEY FACTOR IN INVESTMENT DECISIONS... Quality spreads play an important role in the investment decisions of municipal bond portfolio managers. The widening of spreads may suggest a developing opportunity. If spreads have widened appreciably, the investor may detect an unusual opportunity in a lower-quality, higher-yielding bond. Conversely, if lower-quality bonds have significantly outperformed high-quality bonds over a period, the resulting narrowing of spreads may signal the need for caution. This "spread compression" may prompt portfolio managers to upgrade their portfolios with higher-quality bonds because they are no longer being adequately compensated for the risk of owning lower-quality bonds. While quality spreads are a key metric for municipal bond investors, they represent just one of many factors considered in establishing a diversified bond portfolio. At Eaton Vance, we realize that complex markets require intensive research, a need that emphasizes once again the value of experienced, professional portfolio management. Sincerely, /s/ Thomas J.

The passage of significant tax legislation appeared to give consumer spending a boost. Capital spending, which has lagged the recovery rate of past expansions, was at last showing signs of recovery in late summer and early fall, as manufacturers of industrial equipment reported stronger orders. TECHNOLOGY, RETAILING AND CONSTRUCTION HAVE LED THE ECONOMY IN THE EARLY STAGES OF RECOVERY... A beginning recovery was evident in several key sectors of the economy. Technology companies, especially semiconductor manufacturers and suppliers, have reported robust demand. The manufacturing sector also saw a pickup in activity, with industrial segments, such as machine tools, faring well, as factories began to refit their plants. The retail sector - with the exception of weak auto sales - - was very strong, as consumer confidence rose and tax cuts filtered into consumers' pockets. Despite a rise in mortgage rates, residential construction maintained its strong momentum, although the commercial side was quite sluggish. WITH SLOW JOB GROWTH AND MANAGEABLE INFLATION, THE FEDERAL RESERVE HAS KEPT INTEREST RATES LOW... Gross Domestic Product expanded 3.3% in the second quarter of 2003, followed by a 7.2% rise in the third quarter. However, despite the rebounding economy, the labor market remained stagnant through much of the year - the nation's jobless rate was 6.1% in September 2003. While large employers were slow to rehire, the pace of layoffs slowed considerably. Job growth was stronger among temporary agencies and smaller firms, which have generated the lion's share of new jobs in recent years. Core inflation has generally been contained. Prices for finished goods, consumer staples and services have seen little change. However, prices for some commodities have witnessed a sharp rise, including lumber, plywood, steel and natural gas. Meanwhile, gasoline prices, which spiked dramatically during the prime summer driving season, have since fallen back slightly. With inflation largely held at bay, the Federal Reserve has maintained an accommodative monetary policy. The Fed lowered its Federal Funds rate - a key short-term interest rate barometer - to 1.00% in June.

However, while the decline in short-term interest rates helped revive the stock market, longer-term interest rates moved slightly higher, prompting a bond market pullback. Ten-year Treasury bond yields - which were at 3.59% at September 30, 2002 - rose to 3.93% by September 30, 2003 in response to a reviving economy. The Lehman Brothers Municipal Bond Index had a total return of 3.89% for the year ended September 30, 2003.* FACING RISING BUDGET SHORTFALLS, BELEAGUERED STATES HAVE BEEN FORCED TO RAISE TAXES... Despite lower federal tax rates, the rationale for tax-exempt income has remained intact. Many state governments have enacted income tax hikes and fee increases to make up for revenue shortfalls and budget deficits. Thus, while one portion of the tax burden has fallen, another portion has grown more onerous for many taxpayers. For that reason, we believe that municipal bonds will continue to present interesting investment opportunities and to merit a place in the portfolios of tax-conscious investors. *It is not possible to invest directly in an Index.

FETTER] Thomas J. Fetter Portfolio Manager MANAGEMENT UPDATE - - The U.S. economy gathered new momentum in 2003. Consumer-based sectors, such as retail, have mounted a recovery, housing remains relatively strong and manufacturing appears to be on the mend in many sections of the nation. The nation's jobless rate was 6.1% in September 2003, up from 5.6% a year ago. - - The Fund's largest sector weighting was insured* transportation bonds. The nation's transportation infrastructure is undergoing a dramatic overhaul to meet the needs of the next century. The Fund's holdings included issues for rapid transit, toll roads and bridges, monorails and highways. - - Insured general obligations (GOs)* were a significant commitment for the Fund. Amid an uncertain recovery, a weak revenue outlook has raised the specter of budget deficits for many state and cities. As a consequence, the insured* GO sector has drawn more attention from investors. - - In a slow economic recovery, management emphasized public purpose bonds that are relatively immune to economic fluctuations. Consistent with that approach, the Fund had a large investment in insured* water and sewer bonds, whose revenues derive from non-discretionary water bill payments. - - In a changing interest rate environment, management continued to fine-tune the Fund's coupon structure. Management was able to take advantage of an increase in retail demand to make these adjustments.

CLEMSON] Cynthia J. Clemson Portfolio Manager MANAGEMENT UPDATE - - The California economy showed signs of a rebound in 2003, although the pace of recovery remained slow. Health care, hospitality and residential construction were the major sources of new jobs. Manufacturing remained sluggish, with technology still slow to gain traction. The state's September 2003 jobless rate was 6.4%, down from 6.7% a year ago. - - Insured* transportation bonds were the Fund's largest sector weighting at September 30, 2003. Given the state's vast geography, the efficient transport of passengers and freight is a key segment of California's economy. The Fund's investments included issues for airport authorities, mass transit and toll bridges. - - Insured* general obligations (GOs) were key components of the Fund. Given the state's budgetary issues, the insured* nature of the bonds added an additional measure of protection, and provided quality and a dependable revenue stream. - - Insured* lease revenue/certificates of participation constituted significant investments. These issues provided financing for a broad range of public projects, including the Sacramento City Hall Redevelopment and the San Jose Civic Center. - - Insured* special tax revenue bonds were a major commitment for the Fund. These issues provide municipalities an alternative financing method for the infrastructure, utilities and transportation projects that are needed to support California's population growth.

FETTER] Thomas J. Fetter Portfolio Manager MANAGEMENT UPDATE - - The New York economy has showed positive trends in 2003. The mid-August power outage had only a minor impact on economic activity, mainly on retailers and temporary agencies. Manufacturing and port activity improved, while housing and hospitality markets remained strong. The state's September 2003 jobless rate was 6.4%, up from 6.0% a year ago. - - Insured* transportation bonds were the Fund's largest sector weighting at September 30, 2003. Among the Fund's investments were bonds for thruways, bridges and tunnels, port authorities and the New York City mass transit authority. - - While insured* hospital bonds constituted a large Fund weighting, management was very selective within the sector. In a very competitive market, the Fund focused on the state's top tier institutions, including New York Presbyterian Hospital and Memorial Sloan-Kettering. - - The Fund's insured* education bonds were deemed attractive for their stable tuition revenues. Investments included some of the state's most esteemed institutions, such as Rochester Institute of Technology, Rockefeller University and New York Medical College. - - The Fund has continued to pursue broad diversification by sector, issuer and coupon distribution. In addition, amid a quickening pace of refundings, call protection remained a prime strategic consideration.

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 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, 2003, the Funds, for federal income tax purposes, had capital loss carryovers which will reduce 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 Funds of any liability for federal income or excise tax. The amounts and expiration dates of the capital loss carryovers are as follows: <Table> <Caption> FUND AMOUNT EXPIRES ---------------------------------------------------------------------------- Insured Municipal Fund $ 1,076,715 September 30, 2011 Insured California Municipal Fund 672,504 September 30, 2011 Insured New York Municipal Fund 1,251,495 September 30, 2011 </Table> Additionally, at September 30, 2003, Insured Municipal Fund, Insured California Fund and Insured New York Fund had net capital losses of $6,521,683, $4,261,210 and $164,124, respectively, attributable to security transactions incurred after October 31, 2002. These capital losses are treated as arising on the first day of each Fund's taxable year ending September 30, 2004. 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 27 <Page> 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 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. H 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. 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. Special dividend periods were set on the following series: <Table> <Caption> DIVIDEND EFFECTIVE PERIOD DIVIDEND MATURITY FUND DATE (DAYS) RATE DATE --------------------------------------------------------------------------------------- Insured Municipal Fund Series B March 4, 2003 364 1.18% March 2, 2004 Insured Municipal Fund Series C August 6, 2003 728 1.70% August 3, 2005 Insured Municipal Fund Series D August 7, 2003 364 1.15% August 5, 2004 Insured New York Fund Series A August 4, 2003 364 1.05% August 2, 2004 </Table> Insured Municipal Fund Series B, Series C, Series D and Insured New York Fund Series A will pay each series' accumulated dividends on the first business day of each month. Each series within a Fund is identical in all respects to the other(s), except for the dates of reset for the dividend rates. Auction Preferred Shares issued and outstanding as of September 30, 2003 and dividend rate ranges for the year ended September 30, 2003 are as indicated below: <Table> <Caption> PREFERRED SHARES DIVIDENDS RATE FUND ISSUED AND OUTSTANDING RANGES --------------------------------------------------------------------------- Insured Municipal Fund Series A 4,740 0.51%-1.60% Insured Municipal Fund Series B 4,740 0.90%-1.55% Insured Municipal Fund Series C 4,740 0.58%-1.70% Insured Municipal Fund Series D 4,740 0.60%-1.55% Insured Municipal Fund Series E 4,740 0.60%-1.55% Insured California Fund Series A 3,900 0.40%-1.45% Insured California Fund Series B 3,900 0.40%-1.45% Insured New York Fund Series A 2,850 0.65%-1.65% Insured New York Fund Series B 2,850 0.55%-1.60% </Table> 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 APS. Distributions are recorded on the ex-dividend date. Distribution to preferred shareholders are recorded daily and are payable at the end of each dividend period. Each dividend payment period for the APS is generally seven days. Insured Municipal Fund Series B and Series D shares and Insured New York Series A shares set a special dividend period of 364 days effective March 4, 2003, August 7, 2003 and August 4, 2003, respectively. Insured 28 <Page> Municipal Fund Series C shares set a special dividend period of 728 days effective August 6, 2003. Insured Municipal Fund Series B, Series C, Series D and Insured New York Fund Series A will pay each Series' accumulated dividends on the first business day of each month. The applicable dividend rate for APS on September 30, 2003 are listed below. For the year ended September 30, 2003, the amount of dividends each Fund paid to Auction Preferred shareholders and average APS dividend rates for such period were as follows: <Table> <Caption> DIVIDENDS PAID TO AVERAGE APS APS PREFERRED SHAREHOLDERS DIVIDEND RATES DIVIDEND RATES FOR THE YEAR FOR THE YEAR AS OF ENDED ENDED SEPTEMBER 30, SEPTEMBER 30, SEPTEMBER 30, FUND 2003 2003 2003 ------------------------------------------------------------------------------------- Insured Municipal Fund Series A 0.64% $ 1,086,544 0.99% Insured Municipal Fund Series B 1.18% 1,276,632 1.17% Insured Municipal Fund Series C 1.70% 1,234,245 1.14% Insured Municipal Fund Series D 1.15% 1,176,053 1.09% Insured Municipal Fund Series E 0.95% 1,097,964 1.00% Insured California Fund Series A 0.88% 829,023 0.92% Insured California Fund Series B 0.90% 856,273 0.95% Insured New York Fund Series A 1.05% 721,620 1.11% Insured New York Fund Series B 0.95% 681,433 1.03% </Table> 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 year ended September 30, 2003, the fee was equivalent to 0.65% of each Fund's average weekly gross assets and amounted to $9,563,761, $3,147,936, and $2,310,673 for Insured Municipal Fund, Insured California Fund and Insured New York Fund, respectively. EVM also serves as the administrator of the Funds, but currently receives no compensation. In addition, EVM has contractually agreed to reimburse the Fund for fees and other expenses in the amount of 0.32% of average weekly gross assets of each Fund during the first five full years of each Fund's operations, 0.24% of average weekly gross assets of each Fund in year six, 0.16% in year seven and 0.08% in year eight. For the year ended September 30, 2003, EVM contractually waived $4,723,082, $1,555,160 and $1,137,562 of its advisory fee for Insured Municipal Fund, Insured California Fund and Insured New York Fund, respectively. Certain officers and one Trustee of each Fund are officers of the above organization. 5 INVESTMENTS Purchases and sales of investments, other than U.S. Government securities and short-term obligations, for the year ended September 30, 2003 were as follows: <Table> Insured Municipal Fund Purchases $ 1,505,190,345 Sales 916,497,961 Insured California Fund Purchases $ 383,731,844 Sales 185,922,558 Insured New York Fund Purchases $ 375,138,866 Sales 221,155,982 </Table> 29 <Page> 6 FEDERAL INCOME TAX BASIS OF UNREALIZED APPRECIATION (DEPRECIATION) The cost and unrealized appreciation (depreciation) in value of the investments owned by each Fund at September 30, 2003, as computed for Federal income tax purposes, were as follows: <Table> Insured Municipal Fund Aggregate cost $ 1,498,813,515 ----------------------------------------------------------------- Gross unrealized appreciation $ 43,229,722 Gross unrealized depreciation (5,025,004) ----------------------------------------------------------------- Net unrealized appreciation $ 38,204,718 ----------------------------------------------------------------- Insured California Fund Aggregate cost $ 495,152,154 ----------------------------------------------------------------- Gross unrealized appreciation $ 7,300,237 Gross unrealized depreciation (1,512,719) ----------------------------------------------------------------- Net unrealized appreciation $ 5,787,518 ----------------------------------------------------------------- Insured New York Fund Aggregate cost $ 357,049,900 ----------------------------------------------------------------- Gross unrealized appreciation $ 7,381,742 Gross unrealized depreciation (415,797) ----------------------------------------------------------------- Net unrealized appreciation $ 6,965,945 ----------------------------------------------------------------- </Table> 7 SHARES OF BENEFICIAL INTEREST Each Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional $0.01 par value common shares. Transactions in Fund shares were as follows: <Table> <Caption> INSURED MUNICIPAL FUND ------------------------ YEAR ENDED SEPTEMBER 30, ------------------------ 2003 2002(1) ----------------------------------------------------------------- Sales 1,500,000 63,100,000 ----------------------------------------------------------------- Net increase 1,500,000 63,100,000 ----------------------------------------------------------------- </Table> <Table> <Caption> INSURED CALIFORNIA FUND ------------------------ YEAR ENDED SEPTEMBER 30, ------------------------ 2003 2002(1) ----------------------------------------------------------------- Sales 515,000 21,100,000 Shares issued pursuant to the Trust's dividend reinvestment plan 6,535 -- ----------------------------------------------------------------- Net increase 521,535 21,100,000 ----------------------------------------------------------------- </Table> <Table> <Caption> INSURED NEW YORK FUND ------------------------ YEAR ENDED SEPTEMBER 30, ------------------------ 2003 2002(1) ----------------------------------------------------------------- Sales 430,000 15,225,000 Shares issued pursuant to the Trust's dividend reinvestment plan 36,478 -- ----------------------------------------------------------------- Net increase 466,478 15,225,000 ----------------------------------------------------------------- </Table> (1) For the period from the start of business, August 30, 2002 to September 30, 2002. 8 FINANCIAL INSTRUMENTS Each Fund may trade in financial instruments with off-balance sheet risk in the normal course of its investing activities to assist in managing exposure to various market risks. 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 September 30, 2003 is as follows: Futures Contracts <Table> <Caption> EXPIRATION NET UNREALIZED FUND DATE CONTRACTS POSITION DEPRECIATION ------------------------------------------------------------------------------------------ Insured Municipal 12/03 1,660 U.S. Treasury Bond Short $ (10,067,524) ------------------------------------------------------------------------------------------ Insured California 12/03 705 U.S. Treasury Bond Short $ (3,658,336) ------------------------------------------------------------------------------------------ Insured New York 12/03 125 U.S. Treasury Bond Short $ (791,578) </Table> 30 <Page> At September 30, 2003, each Fund had sufficient cash and/or securities to cover margin requirements on open futures contracts. 9 ANNUAL MEETING OF SHAREHOLDERS (UNAUDITED) Each Fund held its Annual Meeting of Shareholders on July 25, 2003.

These financial statements and financial highlights are the responsibility of the Funds' management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. Our procedures included confirmation of securities held as of September 30, 2003 by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, such financial statements and financial highlights, referred to above, present fairly, in all material respects, the financial position of Eaton Vance Insured Municipal Bond Fund, Eaton Vance Insured California Municipal Bond Fund, and Eaton Vance Insured New York Municipal Bond Fund at September 30, 2003, the results of their operations for the year then ended, the changes in their net assets and their financial highlights for the year then ended and the period from the start of business, August 30, 2002 to September 30, 2002, in conformity with accounting principles generally accepted in the United States of America. DELOITTE & TOUCHE LLP Boston, Massachusetts November 18, 2003 32 <Page> 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.
