In addition, our Privacy Policy only applies to those Eaton Vance customers who are individuals and who have a direct relationship with us. If a customer's account (i.e. fund shares) is held in the name of a third-party financial adviser/broker-dealer, it is likely that only such adviser's privacy policies apply to the customer. This notice supersedes all previously issued privacy disclosures.

For more information about Eaton Vance's Privacy Policy, please call 1-800-262-1122.

Delivery of Shareholder Documents. The Securities and Exchange Commission (the "SEC") permits funds to deliver only one copy of shareholder documents, including prospectuses, proxy statements and shareholder reports, to fund investors with multiple accounts at the same residential or post office box address. 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.

Your instructions that householding not apply to delivery of your Eaton Vance documents will be effective within 30 days of receipt by Eaton Vance or your financial adviser.

Portfolio Holdings. Each Eaton Vance Fund and it's underlying Portfolio (if applicable) will file a schedule of its portfolio holdings on Form N-Q with the SEC for the first and third quarters of each fiscal year. The Form N-Q will be available on the Eaton Vance website www.eatonvance.com, by calling Eaton Vance at 1-800-262-1122 or in the EDGAR database on the SEC's website at www.sec.gov. Form N-Q may also be reviewed and copied at the SEC's public reference room in Washington, D.C. (call 1-800-732-0330 for information on the operation of the public reference room).

Proxy Voting. From time to time, funds are required to vote proxies related to the securities held by the funds. The Eaton Vance Funds or their underlying Portfolios (if applicable) vote proxies according to a set of policies and procedures approved by the Funds' and Portfolios' Boards. You may obtain a description of these policies and procedures and information on how the Funds or Portfolios voted proxies relating to portfolio securities during the most recent 12 month period ended June 30, without charge, upon request, by calling 1-800-262-1122. This description is also available on the SEC's website at www.sec.gov.

Eaton Vance Insured Municipal Bond Funds as of March 31, 2006

 

INVESTMENT UPDATE

 

Eaton Vance Insured Municipal Bond Funds (the “Funds”) are designed to provide current income exempt from regular federal income tax, federal alternative minimum tax and, in state specific funds, state personal income taxes. The Funds invest primarily in high-grade municipal securities that are insured as to the timely payment of principal and interest.

 

Economic and Market Conditions

 

The economy expanded at a 4.8% pace in the first quarter of 2006, an increase from the 1.7% rate in the fourth quarter. Even with a cooling housing market, the economy generated respectable growth in 2005 and early 2006. Despite high energy prices, rising mortgage rates and a persistent tightening by the Federal Reserve (the “Fed”), the economy continued to create jobs – 211,000 in March 2006. The economy appeared to be sustaining growth in both the manufacturing and service sectors, with moderate signs of inflationary pressures.

 

Investor sentiment regarding the Fed’s monetary policy appears to have stabilized in recent months as investors have begun to anticipate the end of the Fed’s series of interest rate hikes (which began in June 2004). The Fed has raised rates at all 15 of the last Open Market Committee meetings, with the current Federal Funds rate standing at 4.75%.

 

Boosted by lower-than-anticipated long-term interest rates, the municipal market saw record supply in 2005, more than $400 billion in new issuance. However, supply has lagged thus far in 2006, contributing to municipal bond outperformance. At March 31, 2006, long-term AAA-rated insured municipal bonds yielded 93% of U.S. Treasury bonds with similar maturities.*

 

For the six months ended March 31, 2006, the Lehman Brothers Municipal Bond Index† (the “Index”), a broadbased, unmanaged municipal market index, posted a modest gain of 0.98%. For information about each Fund’s performance and the performance of funds in the same Lipper Classification†, see the Performance Information and Portfolio Composition pages that follow.

 

Management Discussion

 

The Funds invest primarily in bonds with maturities of 10 years or longer, as longer-maturity bonds historically have provided greater tax-exempt income for investors than shorter-maturity bonds. Given the flattening of the yield curve for fixed-income securities over the past 18 months — with shorter-maturity yields rising more than longer-maturity yields — the long end of the curve was a relatively attractive place to be positioned. However, given the leveraged nature of the Funds, rising short term rates have increased the borrowing costs associated with the leverage. As borrowing costs have risen, the income generated by the Funds has declined. Please see the Performance Information and Portfolio Compostion pages that follow for a description of each Fund’s leverage as of March 31, 2006.

 

During the six months ended March 31, 2006, the Fed raised short-term interest rates at regular intervals, and commodities prices rose significantly. However, the economy grew at a solid pace, with moderate inflation. In this climate, Fund management continued to maintain a somewhat cautious outlook on interest rates and positioned the Funds’ durations accordingly. Duration measures a bond fund’s sensitivity to changes in interest rates.

 

During the past year, management invested in bonds with attractive coupons and long call protection. These strategies contributed positively to the Funds’ performances over the 6-month period.

 

Management continued to focus on finding relative value within the marketplace — in issuer names, coupons, maturities and sectors. Relative value trading, which seeks to capitalize on undervalued securities, has enhanced the Funds’ returns during the year. Finally, management continued to monitor closely call protection in the Funds. Call protection remains an important strategic consideration for municipal bond investors, especially because refinancing activity has increased over the past six months.

† It is not possible to invest directly in an Index or Lipper Classification. The Index’s total return does not reflect expenses that would have been incurred if an investor individually purchased or sold the securities represented in the Index.

Past performance is no guarantee of future results.

 

Fund shares are not insured by the FDIC and are not deposits or other obligations of, or guaranteed by, any depository institution. Shares are subject to investment risks, including possible loss of principal invested.

 

The views expressed throughout this report are those of the portfolio managers and are current only through the end of the period of the report as stated on the cover. These views are subject to change at any time based upon market or other conditions, and the investment adviser disclaims any responsibility to update such views. These views may not be relied on as investment advice and, because investment decisions for a fund are based on many factors, may not be relied on as an indication of trading intent on behalf of any Eaton Vance fund.

Past performance is no guarantee of future results. Returns are historical and are calculated by determining the percentage change in net asset value or share price (as applicable) with all distributions reinvested. Investment return and principal value will fluctuate so that shares, when sold, may be worth more or less than their original cost. Fund performance during certain periods reflects the strong bond market performance and/or the strong performance of bonds held during those periods. This performance is not typical and may not be repeated. Performance is for the stated time period only; due to market volatility, the Fund’s current performance may be lower or higher than the quoted return.

The Fund invests primarily in debt securities issued by municipalities. The ability of the issuers of the debt securities to meet their obligations may be affected by economic developments in a specific industry or municipality. In order to reduce the risk associated with such economic developments, at March 31, 2006, 84.4% of total investments are backed by bond insurance of various financial institutions and financial guaranty assurance agencies. The aggregate percentage insured by an individual financial institution ranged from 1.3% to 24.7% of total investments.

The Fund invests primarily in debt securities issued by California municipalities. The ability of the issuers of the debt securities to meet their obligations may be affected by economic developments in a specific industry or municipality. In order to reduce the risk associated with such economic developments, at March 31, 2006, 83.0% of total investments are backed by bond insurance of various financial institutions and financial guaranty assurance agencies. The aggregate percentage insured by an individual financial institution ranged from 2.4% to 23.5% of total investments.

(1)  Security (or a portion thereof) has been segregated to cover margin requirements on open financial futures contracts.

The Fund invests primarily in debt securities issued by New York municipalities. The ability of the issuers of the debt securities to meet their obligations may be affected by economic developments in a specific industry or municipality. In order to reduce the risk associated with such economic developments, at March 31, 2006, 81.8% of total investments are backed by bond insurance of various financial institutions and financial guaranty assurance agencies. The aggregate percentage insured by an individual financial institution ranged from 2.6% to 36.0% of total investments.

(4)  Total investment return on net asset value is calculated assuming a purchase at the offering price of $15.000 less the sales load of $0.675 per share paid by the shareholder on the first day and a sale at the net asset value on the last day of the period reported. Total investment return on market value is calculated assuming a purchase at the offering price of $15.000 less the sales load of $0.675 per share paid by the shareholder on the first day and a sale at the current market price on the last day of the period reported. Total investment return on net asset value and total investment return on market value are not computed on an annualized basis.

(5)  Returns are historical and are calculated by determining the percentage change in net asset value or market value with all distributions reinvested. Total return is not computed on an annualized basis.

(6)  Ratios do not reflect the effect of dividend payments to preferred shareholders. Ratios to average net assets applicable to common shares reflect the Fund's leveraged capital structure.

(7)  Annualized.

(8)  Calculated by subtracting the Fund's total liabilities (not including the preferred shares) from the Fund's total assets, and dividing this by the number of preferred shares outstanding.

(9)  Plus accumulated and unpaid dividends.

Eaton Vance Insured Municipal Bond Funds as of March 31, 2006

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 a Fund or collectively the Funds) are registered under the Investment Company Act of 1940 (the 1940 Act), 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 and taxable obligations, if any, are normally valued on the basis of valuations furnished by a pricing service. Financial futures contracts and options on financial futures contracts listed on the commodity exchanges are valued at closing settlement prices. Over-the-counter options on financial futures contracts are normally valued at the mean between the latest bid and asked prices. Interest rate swaps are normally valued on the basis of valuations furnished by a pricing service. 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, and investments for which the price of the security is not believed to represent its fair market value, are valued at fair value using methods determined in good faith by or at the direction of the Trustees.

B  Income — Interest income is determined on the basis of interest accrued, adjusted for amortization of premium or discount.

C  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, 2005, 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:

Fund   Amount   Expires  
Insured Municipal Fund   $ 1,072,880     September 30, 2011  
      4,954,488     September 30, 2013  
Insured California Fund     557,635     September 30, 2011  
      10,557,537     September 30, 2013  
Insured New York Fund     1,251,495     September 30, 2011  
      1,166,633     September 30, 2012  
      5,433,153     September 30, 2013  

 

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.

D  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.

E  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.

25



Eaton Vance Insured Municipal Bond Funds as of March 31, 2006

NOTES TO FINANCIAL STATEMENTS (Unaudited) CONT'D

F  Options on Futures Contracts — Upon the purchase of a put option on a financial futures contract by a Fund, the premium paid is recorded as an investment, the value of which is marked-to-market daily. When a purchased option expires, a Fund will realize a loss in the amount of the cost of the option. When a Fund enters into a closing sale transaction, a Fund will realize a gain or loss depending on whether the sales proceeds from the closing sale transaction are greater or less than the cost of the option. When a Fund exercises a put option, settlement is made in cash. The risk associated with purchasing put options is limited to the premium originally paid.

G  When-Issued and Delayed Delivery Transactions — The Funds may engage in when-issued and delayed delivery transactions. The Funds record when-issued securities on trade date and maintain security positions such that sufficient liquid assets will be available to make payments for the securities purchased. Securities purchased on a when-issued or delayed delivery basis are marked-to-market daily and begin earning interest on settlement date.

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  Indemnifications — Under each Fund's organizational documents, its officers and Trustees may be indemnified against certain liabilities and expenses arising out of the performance of their duties to each Fund and shareholders are indemnified against personal liability for the obligations of each Fund. Additionally, in the normal course of business, each Fund enters into agreements with service providers that may contain indemnification clauses. Each Fund's maximum exposure under these arrangements is unknown as this would involve future claims that may be made against each Fund that have not yet occurred.

J  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 credit balances used to reduce the Funds' custodian fees are reported as a reduction of total expenses in the Statements of Operations.

K  Other — Investment transactions are accounted for on a trade date basis. Realized gains and losses are computed based on the specific identification of the securities sold.

L  Interim Financial Statements — The interim financial statements relating to March 31, 2006 and for the six months then ended have not been audited by an independent registered public accounting firm, 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 generally have been reset every seven days thereafter by an auction, unless a special dividend period has been set. 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 March 31, 2006 and dividend rate ranges for the six months ended March 31, 2006 are as indicated below:

Fund   Preferred Shares
Issued and Outstanding
  Dividends Rate
Ranges
 
Insured Municipal Series A     4,740       2.30 % – 4.73%  
Insured Municipal Series B     4,740       0.80 % – 4.00%  
Insured Municipal Series C     4,740       2.50 % – 5.15%  
Insured Municipal Series D     4,740       2.30 % – 4.00%  
Insured Municipal Series E     4,740       2.18 % – 3.90%  
Insured California Series A     3,900       2.00 % – 3.35%  
Insured California Series B     3,900       2.04 % – 3.30%  
Insured New York Series A     2,850       2.25 % – 3.30%  
Insured New York Series B     2,850       2.30 % – 3.25%  

 

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. Distributions of realized capital gains, if any, are made at least annually. Distributions 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. The applicable dividend rate for APS on March 31, 2006 are listed below. For the six months ended March 31, 2006, the amount of dividends each Fund paid to Auction Preferred shareholders and average APS dividend rates for such period were as follows:

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.

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, 2006, the fee was equivalent to 0.65% (annualized) of each Fund's average weekly gross assets and amounted to $5,122,374, $1,665,337, and $1,209,754 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 six months ended March 31, 2006, EVM contractually waived $2,521,784, $819,808 and $595,571 of its advisory fee for Insured Municipal Fund, Insured California Fund and Insured New York Fund, respectively.

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.

BOARD OF TRUSTEES' ANNUAL APPROVAL OF THE INVESTMENT ADVISORY AGREEMENTS

Overview of the Contract Review Process

The Investment Company Act of 1940, as amended (the "1940 Act"), provides, in substance, that each investment advisory agreement between a fund and its investment adviser will continue in effect from year to year only if its continuance is approved at least annually by the fund's board of trustees, including by a vote of a majority of the trustees who are not "interested persons" of the fund ("Independent Trustees") cast in person at a meeting called for the purpose of considering such approval.

At a meeting of the Boards of Trustees (each a "Board") of the Eaton Vance group of mutual funds (the "Eaton Vance Funds") held on March 27, 2006, the Board, including a majority of the Independent Trustees, voted to approve continuation of existing advisory and sub-advisory agreements for the Eaton Vance Funds for an additional one-year period. In voting its approval, the Board relied upon the affirmative recommendation of the Special Committee of the Board, which is a committee comprised exclusively of Independent Trustees. Prior to making its recommendation, the Special Committee reviewed information furnished for a series of meetings of the Special Committee held in February and March 2006. Such information included, among other things, the following:

Information about Fees, Performance and Expenses

•  An independent report comparing the advisory and related fees paid by each fund with fees paid by comparable funds;

•  An independent report comparing each fund's total expense ratio and its components to comparable funds;

•  An independent report comparing the investment performance of each fund to the investment performance of comparable funds over various time periods;

•  Data regarding investment performance in comparison to relevant peer groups of funds and appropriate indices;

•  Comparative information concerning fees charged by each adviser for managing other mutual funds and institutional accounts using investment strategies and techniques similar to those used in managing the fund;

•  Profitability analyses for each adviser with respect to each fund managed by it;

Information about Portfolio Management

•  Descriptions of the investment management services provided to each fund, including the investment strategies and processes employed;

•  Information concerning the allocation of brokerage and the benefits received by each adviser as a result of brokerage allocation, including information concerning the acquisition of research through "soft dollar" benefits received in connection with the funds' brokerage, and the implementation of a soft dollar reimbursement program established with respect to the funds;

•  Data relating to portfolio turnover rates of each fund;

•  The procedures and processes used to determine the fair value of fund assets and actions taken to monitor and test the effectiveness of such procedures and processes;

Information about the Adviser

•  Reports detailing the financial results and condition of each adviser;

•  Descriptions of the qualifications, education and experience of the individual investment professionals whose responsibilities include portfolio management and investment research for the funds, and information relating to their compensation and responsibilities with respect to managing other mutual funds and investment accounts;

•  Copies of the Codes of Ethics of each adviser and its affiliates, together with information relating to compliance with and the administration of such codes;

•  Information concerning the resources devoted to compliance efforts undertaken by each adviser and its affiliates on behalf of the funds (including descriptions of various compliance programs) and their record of compliance with investment policies and restrictions, including policies with respect to market-timing, late trading and selective portfolio disclosure, and with policies on personal securities transactions;

•  Descriptions of the business continuity and disaster recovery plans of each adviser and its affiliates;

Other Relevant Information

•  Information concerning the nature, cost and character of the administrative and other non-investment management services provided by Eaton Vance Management and its affiliates;

•  Information concerning management of the relationship with the custodian, subcustodians and fund accountants by each adviser or the funds' administrator; and

•  The terms of each advisory agreement.

BOARD OF TRUSTEES' ANNUAL APPROVAL OF THE INVESTMENT ADVISORY AGREEMENT CONT'D

In addition to the information identified above, the Special Committee considered information provided from time to time by each adviser throughout the year at meetings of the Board and its committees. Over the course of the twelve month period ended March 31, 2006, the Board met nine times and the Special Committee, the Audit Committee and the Governance Committee, each of which is a Committee comprised solely of Independent Trustees, met eight, twelve and five times, respectively. At such meetings, the Trustees received, among other things, presentations by the portfolio managers and other investment professionals of each adviser relating to the investment performance of each fund and the investment strategies used in pursuing the fund's investment objective.

For funds that invest through one or more underlying portfolios, the Board considered similar information about the portfolio(s) when considering the approval of advisory agreements. In addition, in cases where the fund's investment adviser has engaged a sub-adviser, the Board considered similar information about the sub-adviser when considering the approval of any sub-advisory agreement.

The Special Committee was assisted throughout the contract review process by Goodwin Procter LLP, legal counsel for the Independent Trustees. The members of the Special Committee relied upon the advice of such counsel and their own business judgment in determining the material factors to be considered in evaluating each advisory and sub-advisory agreement and the weight to be given to each such factor. The conclusions reached with respect to each advisory and sub-advisory agreement were based on a comprehensive evaluation of all the information provided and not any single factor. Moreover, each member of the Special Committee may have placed varying emphasis on particular factors in reaching conclusions with respect to each advisory and sub-advisory agreement.

Results of the Process

Based on its consideration of the foregoing, and such other information as it deemed relevant, including the factors and conclusions described below, the Special Committee concluded that the continuance of the investment advisory agreements of the following funds:

•  Insured Municipal Bond Fund

•  Insured California Municipal Bond Fund

•  Insured New York Municipal Bond Fund

(the "Funds"), each with Eaton Vance Management (the "Adviser"), including their fee structures, is in the interests of shareholders and, therefore, the Special Committee recommended to the Board approval of each agreement. The Board accepted the recommendation of the Special Committee as well as the factors considered and conclusions reached by the Special Committee with respect to each agreement. Accordingly, the Board, including a majority of the Independent Trustees, voted to approve continuation of the advisory agreement for each Fund.

Nature, Extent and Quality of Services

In considering whether to approve the investment advisory agreements of the Funds, the Board evaluated the nature, extent and quality of services provided to the Funds by the Adviser.

The Board considered the Adviser's management capabilities and investment process with respect to the types of investments held by each Fund, including the education, experience and number of its investment professionals and other personnel who provide portfolio management, investment research, and similar services to the Funds. In particular, the Board evaluated, where relevant, the abilities and experience of such investment personnel in analyzing factors such as credit risk, tax efficiency, and special considerations relevant to investing in municipal bonds. Specifically, the Board considered the Adviser's 30-person municipal bond team, which includes six portfolio managers and nine credit specialists who provide services to the Funds. The Board also took into account the resources dedicated to portfolio management and other services, including the compensation paid to recruit and retain investment personnel, and the time and attention devoted to each Fund in the complex by senior management.

The Board reviewed the compliance programs of the Adviser and relevant affiliates thereof. Among other matters, the Board considered compliance and reporting matters relating to personal trading by investment personnel, selective disclosure of portfolio holdings, late trading, frequent trading, portfolio valuation, business continuity and the allocation of investment opportunities. The Board also evaluated the responses of the Adviser and its affiliates to requests from regulatory authorities such as the Securities and Exchange Commission and the National Association of Securities Dealers.

The Board also considered shareholder and other administrative services provided or managed by Eaton Vance Management and its affiliates, including transfer agency and accounting services. The Board evaluated the benefits to shareholders of investing in a fund that is a part of a large family of funds.

33

BOARD OF TRUSTEES' ANNUAL APPROVAL OF THE INVESTMENT ADVISORY AGREEMENT CONT'D

After consideration of the foregoing factors, among others, the Board concluded that the nature, extent and quality of services provided by the Adviser, taken as a whole, are appropriate and consistent with the terms of the respective investment advisory agreements.

Fund Performance

The Board compared each Fund's investment performance to a relevant universe of similarly managed funds identified by an independent data provider and appropriate benchmark indices. The Board reviewed comparative performance data for the one-year and three-year periods ended September 30, 2005 for each Fund. On the basis of the foregoing and other relevant information, the Board concluded that the performance of each Fund is satisfactory.

Management Fees and Expenses

The Board reviewed contractual investment advisory fee rates payable by each Fund (referred to as "management fees").

As part of its review, the Board considered each Fund's management fee and total expense ratio for the one-year period ended September 30, 2005, as compared to a group of similarly managed funds selected by an independent data provider. The Board considered the fact that the Adviser had waived fees and/or paid expenses for each of the Funds.

After reviewing the foregoing information, and in light of the nature, extent and quality of the services provided by the Adviser, the Board concluded with respect to each Fund that the management fee charged to the Fund for advisory and related services and the total expense ratio of the Fund are reasonable.

Profitability

The Board reviewed the level of profits realized by the Adviser and, if applicable, its affiliates in providing investment advisory and administrative services to each Fund and to all Eaton Vance Funds as a group. The Board considered the level of profits realized without regard to revenue sharing or other payments by the Adviser and its affiliates to third parties in respect of distribution services. The Board also considered other direct or indirect benefits received by the Adviser and its affiliates in connection with their relationship with the Funds.

The Board concluded that, in light of the foregoing factors and the nature, extent and quality of the services rendered, the profits realized by the Adviser and its affiliates are reasonable.

Economies of Scale

In reviewing management fees and profitability, the Board also considered the extent to which the Adviser and its affiliates, on the one hand, and each Fund, on the other hand, can expect to realize benefits from economies of scale as the assets of the Fund increase. The Board acknowledged the difficulty in accurately measuring the benefits resulting from the economies of scale with respect to the management of any specific fund or group of funds. The Board also considered the fact that none of the Funds is continuously offered and concluded that, in light of the level of the adviser's profits with respect to each Fund, the implementation of breakpoints in the advisory fee schedule is not appropriate. Based upon the foregoing, the Board concluded that the benefits from economies of scale are currently being shared equitably by the Adviser and its affiliates and each Fund.

Item 7. Disclosure of Proxy Voting Policies and Procedures for Closed-End Management Investment Companies

 

The Board of Trustees of the Trust has adopted a proxy voting policy and procedure (the “Fund Policy”), pursuant to which the Trustees have delegated proxy voting responsibility to the Fund’s investment adviser and adopted the investment adviser’s proxy voting policies and procedures (the “Policies”) which are described below.  The Trustees will review the Fund’s proxy voting records from time to time and will annually consider approving the Policies for the upcoming year.  In the event that a conflict of interest arises between the Fund’s shareholders and the investment adviser, the administrator, or any of their affiliates or any affiliate of the Fund, the investment adviser will generally refrain from voting the proxies related to the companies giving rise to such conflict until it consults with the Board’s Special Committee except as contemplated under the Fund Policy.  The Board’s Special Committee will instruct the investment adviser on the appropriate course of action.

 

The Policies are designed to promote accountability of a company’s management to its shareholders and to align the interests of management with those shareholders.  The investment adviser will generally support company management on proposals relating to environmental and social policy issues, on matters regarding the state of organization of the company and routine matters related to corporate administration which are not expected to have a significant economic impact on the company or its shareholders.  On all other matters, the investment adviser will review each matter on a case-by-case basis and reserves the right to deviate from the Policies’ guidelines when it believes the situation warrants such a deviation.  The Policies include voting guidelines for matters relating to, among other things, the election of directors, approval of independent auditors, executive compensation, corporate structure and anti-takeover defenses.  The investment adviser may abstain from voting from time to time where it determines that the costs associated with voting a proxy outweighs the benefits derived from exercising the right to vote.

 

In addition, the investment adviser will monitor situations that may result in a conflict of interest between the Fund’s shareholders and the investment adviser, the administrator, or any of their affiliates or any affiliate of the Fund by maintaining a list of significant existing and prospective corporate clients.  The investment adviser’s personnel responsible for reviewing and voting proxies on behalf of the Fund will report any proxy received or expected to be received from a company included on that list to members of senior management of the investment adviser identified in the Policies. Such members of senior management will determine if a conflict exists.  If a conflict does exist, the investment adviser will seek instruction on how to vote from the Special Committee.

 

Information on how the Fund voted proxies relating to portfolio securities during the most recent 12 month period ended June 30 is available (1) without charge, upon request, by calling 1-800-262-1122, and (2) on the Securities and Exchange Commission’s website at http://www.sec.gov.

The Secretary shall retain copies of any shareholder recommendations which meet the foregoing requirements for a period of not more than 12 months following receipt.
