Eaton Vance Insured Municipal Bond Funds as of March 31, 2005

LETTER TO SHAREHOLDERS

Thomas J. Fetter

President

The municipal bond market is a center of capital formation for states, municipalities and, in some cases, private economic initiatives. In this edition of our continuing educational series, we will discuss industrial development revenue (IDR) bonds. IDR bonds have long been used as a financing mechanism by local governments to provide assistance to local employers and encourage job retention and creation within their communities.

IDR bonds finance private activities that benefit the public...

IDR bonds are issued by municipal authorities to finance projects and facilities used by private corporations. Historically, IDR bonds have represented a partnership between the private and public sectors – a source of dedicated funding for companies and a source of job creation in projects beneficial to local communities.  The Private-Activities” provision of the Tax Reform Act of 1986 permits issuance of tax-exempt bonds for specific activities, including pollution control; gas and electric service; water distribution; wastewater systems; solid waste disposal; airports and selected transportation projects; and other industrial projects.

The Act also placed a cap on the dollar amount that may be raised for IDR bonds in each state, limiting the amount to $50 per person/per state/per year, with a $150 million maximum. These limitations provide protection against potential abuse and ensure that tax-exempt IDR bonds will indeed be issued for projects that will benefit the public.

IDR bonds finance utility-related projects and other industrial initiatives...

Typically, IDR bond projects provide financing for manufacturing, processing or utility facilities. Historically, about one-half of these bonds have been issued to finance pollution control facilities for manufacturers and electric utilities. As many utilities and manufacturers have been ordered to comply with stricter environmental and fuel standards, pollution control bonds have helped finance the retrofits of existing plants. Other IDR bonds have served as inducements from state and local issuers to locate plants or build new facilities, in the hope that such construction might generate further economic growth for a community.

IDR bonds are secured by corporate revenues – not those of state or local governments...

IDR bond issues are secured by the credit of the underlying corporation. The municipal issuing authority acts solely as a conduit to permit tax-exempt financing. The corporation pledges to make payments sufficient to meet all debt service obligations. Unlike some revenue issues, IDR bonds are backed by revenues of the entire corporation, not solely by those of the project being financed.

Because IDR bonds are backed by corporate revenues and not by the taxing authority of a state or local jurisdiction, they have historically provided coupon premiums above those of general obligations and other more traditional revenue bonds. Bonds may be either collateralized or unsecured. Collateralized bonds have a lien against the company’s assets, which may provide bond holders enhanced bargaining power in the event of a bankruptcy. Unsecured bonds have no such lien.

While providing new opportunities, IDR bonds require rigorous analysis...

While IDR bonds may provide unusual investment opportunities, they also may entail increased risk and, therefore, demand especially intensive analysis. At Eaton Vance, we have credit analysts and resources dedicated to IDR bond research.

IDR bonds represent a key segment of the municipal bond market and should remain an important source of capital formation. In our view, the experience and resources needed to evaluate these issues further demonstrates the value of professional management. We will continue to look for opportunities in this sector of the municipal market.

Sincerely,

/s/ Thomas J. Fetter

MARKET RECAP

The U.S. economy continued to generate moderate growth during the six months ended March 31, 2005. While higher gasoline and energy prices pinched consumers, the weak U.S. dollar raised inflationary concerns and helped push interest rates higher.

After a promising recovery in 2004, slower growth in early 2005...

The nation’s Gross Domestic Product grew by 3.1% in the first quarter of 2005, according to preliminary Commerce Department figures, following a 3.8% rise in the fourth quarter of 2004. Manufacturing activity, which had expanded strongly in the second half of 2004, slackened somewhat in the first quarter of 2005, amid slower industrial production and weakening demand for durable goods.

Consumer spending, which helped fuel the economic recovery over the past year, weakened considerably, as higher fuel costs and rising interest rates on loans and mortgages prompted consumers to tighten their belts. Capital spending also slowed, as businesses curtailed new investments in plants and factories, while reducing the pace of investment in productivity-enhancing equipment and software. Residential construction remained relatively strong, although slightly off the torrid pace set in 2004.

After recovering dramatically in 2004, job creation weakened somewhat in early 2005...

The nation’s labor markets strengthened during the year, although the pace of job creation weakened at the close of the period. Hiring picked up during the year in areas that had suffered large technology sector layoffs. Also, manufacturing, financial services, business services, trucking, shipping, construction, energy, health care, and media also generated new jobs. In the first quarter of 2005, however, employers showed some reticence in hiring practices, as they were forced to cope with unpredictable fuel cost hikes.

The Federal Reserve continued to raise short-term interest rates in 2005...

The Federal Reserve pushed short-term rates higher, suggesting it will continue to raise rates to keep the economy from growing too quickly and, thereby, reviving inflation. Beginning in June 2004, the Fed increased its Federal Funds rate – a key short-term interest rate barometer – on eight occasions, raising that benchmark from 1.00% to 3.00%, including its most recent rate hike in May 2005.

The municipal bond market posted a modest gain for the year, slightly outperforming the Treasury market. For the six months ended March 31, 2005, the Lehman Brothers Municipal Bond Index – an unmanaged index of longer-term, investment-grade, municipal debt securities made up of issues larger than $50 million – had a total return of 1.21.%.*

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

The views expressed throughout this report are those of the various 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 Eaton Vance disclaims any responsibility to update such views. These views may not be relied on as investment advice and, because investment decisions for an Eaton Vance fund are based on many factors, may not be relied on as an indication of trading intent on behalf of any Eaton Vance fund.

INVESTMENT UPDATE

The Fund

•Based on share price (traded on the American Stock Exchange), the Fund had a total return of 2.62% for the six months ended March 31, 2005. That return was the result of a decrease in share price from $13.95 on September 30, 2004 to $13.85 on March 31, 2005 and the reinvestment of $0.469 in monthly dividends.(1)

•Based on net asset value, the Fund had a total return of 4.41% for the six months ended March 31, 2005. That return was the result of an increase in net asset value per share from $14.75 on September 30, 2004 to $14.90 on March 31, 2005, and the reinvestment of all distributions.

•In comparison, the Lehman Brothers Municipal Bond Index – an unmanaged index of longer-term, investment-grade, municipal debt securities made up of issues larger than $50 million – had a total return of 1.21% during the six months ended March 31, 2005.(2)

•Based on the last dividend of the semi-annual period and a share price of $13.85, the Fund had a market yield of 6.77% at March 31, 2005.(3) The Fund’s market yield is equivalent to a taxable yield of 10.42%.(4)

Management Discussion

•The U.S. economy expanded moderately during the period, despite concerns over rising fuel costs. Manufacturing rebounded somewhat, while financial services, business services, transportation, construction, energy and health care posted strong job growth. The U.S. jobless rate was 5.2% in March 2005, down from 5.7% a year ago.

•Insured* transportation bonds were again the Fund’s largest sector weighting at March 31, 2005. The Fund’s investments represented a wide range of transportation projects across the nation, including toll bridges, a marine terminal, highway and turnpike authorities and a monorail project.

•Insured* general obligations (GOs) remained prominent investments. The Fund’s holdings included a geographically diversified mix of state, county and municipal issuers representing a wide variety of revenue sources.

•Insured* water and sewer bonds were key investments for the Fund. The Fund’s holdings focused predominantly on large city projects. Water bonds have been issued in greater volume in recent years, as metropolitan areas attempt to upgrade their water and wastewater infrastructures to meet the challenges of economic growth and expanding populations.

•At March 31, 2005, the Fund had leverage in the amount of approximately 38% of the Fund’s total assets. The Fund uses leverage through the issuance of preferred shares. Use of financial leverage creates an opportunity for increased income but, at the same time, creates special risks (including the likelihood of greater volatility of net asset value and market price of common shares).

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 redeemed, may be worth more or less than their original cost. 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.

Management Discussion

•California’s economy generated good job growth in late 2004 and early 2005. The business services sector added the largest number of jobs, with construction and financial services also making significant contributions. The government sector, subject to budgetary restraints, remained a sore spot in the state economy.  The state’s March 2005 jobless rate was 5.8%, down from 6.4% a year ago.

•Insured* general obligations (GOs) constituted the Fund’s largest sector weighting at March 31, 2005. The Fund’s investments focused predominantly on issues for unified school districts and community college districts.

•Insured* lease revenue/certificates of participation (COPs) were major investments. The Fund’s investments enabled cost-effective, lease financing for state, county and municipal borrowers for a broad range of public works projects, including a medical center project, a civic center and a county administration building.

•Insured* transportation bonds provided an attractive income stream. The Fund’s investments represented state, county and local issues for a variety of transportation-related projects, including toll bridges, airport authorities and highway projects.

•At March 31, 2005, the Fund had leverage in the amount of approximately 39% of the Fund’s total assets. The Fund uses leverage through the issuance of preferred shares.

•During 2004 and into early 2005, New York State posted positive job growth for the first time since 2000. Job creation was especially strong in business services, education, health care and tourism. Gains in finance have been modest, while the state continued to lose manufacturing jobs at a faster rate than the nation as a whole. The state’s March 2005 jobless rate was 5.1%, down from 6.1% a year ago.

•Insured* transportation bonds were the Fund’s largest sector weighting at March 31, 2005. With transportation a key to New York’s economic capital, these bonds financed important upgrades. The Fund’s holdings included issues for rapid transit, bridges and tunnels, ports and highway authorities.

•Insured* hospital bonds were a large investment for the Fund. In a competitive and cost-conscious climate, the Fund focused on what management believes to be well-managed, financially sound hospitals, including a Brooklyn-based acute care facility and one of the nation’s leading cancer care and research centers.

•Insured* private education bonds were major holdings. Management focused on dormitory authority and industrial development agency bonds, which helped finance the building of living quarters and classroom facilities for some of the state’s leading colleges and universities.

•At March 31, 2005, the Fund had leverage in the amount of approximately 38% of the Fund’s total assets. The Fund uses leverage through the issuance of preferred shares.

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 (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.

AInvestment Valuation - Municipal bonds are normally valued on the basis of valuations furnished by a pricing service. Taxable obligations, if any, for which price quotations are readily available are normally valued at the mean between the bid and asked prices. Futures contracts and options on futures contracts listed on the commodity exchanges are valued at closing settlement prices. Over-the-counter options on 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 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 not readily available are valued at fair value using methods determined in good faith by or at the direction of the Trustees.

BInvestment 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.

CIncome - Interest income is determined on the basis of interest accrued, adjusted for amortization of premium or discount.

DFederal 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, 2004, 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
Insured California Fund		557,635	September 30, 2011
Insured New York Fund		1,251,495	September 30, 2011
		1,166,633	September 30, 2012

Additionally, at September 30, 2004, Insured Municipal Fund, Insured California Fund and Insured New York Fund had net capital losses of $10,957,039, $10,115,483 and $5,122,077, respectively, attributable to security transactions incurred after October 31, 2003. These are treated as arising on the first day of each Fund's taxable year ending September 30, 2005.

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.

Eaton Vance Insured Municipal Bond Funds as of March 31, 2005

NOTES TO FINANCIAL STATEMENTS (Unaudited)CONT'D

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.

FFinancial 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.

GOptions 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.

HUse 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.

IIndemnifications - 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.

JExpense 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 Statement of Operations.

KInterim Financial Statements - The interim financial statements relating to March 31, 2005 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. Special dividend periods are currently in effect on the following series:

Fund	Effective Date	Dividend Period (Days)		Dividend Rate			Maturity Date
Insured Municipal Series C	August 6, 2003		728		1.70	%	August 3, 2005

Insured Municipal Fund Series C will pay its 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 March 31, 2005 and dividend rate ranges for the six months ended March 31, 2005 are as indicated below:

Trust	Preferred Shares Issued and Outstanding		Dividends Rate Ranges
Insured Municipal Series A		4,740		1.00	% - 2.03%
Insured Municipal Series B		4,740		1.068	% - 2.61%

Insured New York Series A		2,850		1.20	% - 2.15%
Insured New York Series B		2,850		0.91	% - 2.05%

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. Insured Municipal Fund Series C shares set a special dividend period of 728 days effective August 6, 2003. Insured Municipal Fund Series C will pay its accumulated dividends on the first business day of each month. The applicable dividend rate for APS on March 31, 2005 are listed below. For the six months ended March 31, 2005, the amount of dividends each Fund paid to Auction Preferred shareholders and average APS dividend rates for such period were as follows:

Fund	APS Dividend Rates as of March 31, 2005			Dividends Paid to Preferred Shareholders from net investment income for the six months ended March 31, 2005		Average APS Dividend Rates for the six months ended March 31, 2005
Insured Municipal Fund Series A		1.90	%		935,892		1.59	%
Insured Municipal Fund Series B		2.61	%		727,945		1.26	%
Insured Municipal Fund Series C		1.70	%		1,024,129		1.70	%
Insured Municipal Fund Series D		2.15	%		959,139		1.63	%
Insured Municipal Fund Series E		2.15	%		925,375		1.58	%
Insured California Fund Series A		2.21	%		689,781		1.42	%
Insured California Fund Series B		1.75	%		724,659		1.49	%
Insured New York Series A		2.15	%		564,099		1.60	%
Insured New York Series B		1.80	%		489,537		1.39	%

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, 2005, the fee was equivalent to 0.65% (annualized) of each

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.

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.

BOARD OF TRUSTEES' ANNUAL APPROVAL OF THE INVESTMENT ADVISORY AGREEMENTS

The investment advisory agreements between each of Eaton Vance Insured Municipal Bond Fund, Eaton Vance Insured California Municipal Bond Fund and Eaton Vance Insured New York Municipal Bond Fund (collectively the "Funds" or individually the "Fund"), and the investment adviser, Eaton Vance Management ("Eaton Vance"), each provide that the advisory agreement will continue in effect from year to year so long as its continuance is approved at least annually (i) by a vote of a majority of the noninterested Trustees of the Fund cast in person at a meeting called for the purpose of voting on such approval and (ii) by the Trustees of the Fund or by vote of a majority of the outstanding interests of the Fund.

In considering the annual approval of the investment advisory agreements between each Fund and the investment adviser, the Special Committee of the Board of Trustees considered information that had been provided throughout the year at regular Board meetings, as well as information furnished to the Special Committee for a series of meetings held in February and March in preparation for a Board meeting held on March 21, 2005 to specifically consider the renewal of the investment advisory agreements. Such information included, among other things, the following:

•An independent report comparing the advisory fees of each Fund with those of comparable funds;

•  An independent report comparing the expense ratio of each Fund to those of comparable funds;

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

•The economic outlook and the general investment outlook in relevant investment markets;

•Eaton Vance's results and financial condition and the overall organization of the investment adviser;

•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;

•Eaton Vance's management of the relationship with the custodian, subcustodians and fund accountants;

•The resources devoted to Eaton Vance's compliance efforts undertaken on behalf of the funds it manages and the record of compliance with the investment policies and restrictions and with policies on personal securities transactions;

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

•The terms of the advisory agreement and the reasonableness and appropriateness of the particular fee paid by the Fund for the services described therein.

The Special Committee also considered the investment adviser's municipal bond portfolio management capabilities, including information relating to the education, experience, and number of investment professionals and other personnel who provide services under the investment advisory agreements. Specifically, the Special Committee considered the investment adviser's 30-person municipal bond team, which includes six portfolio managers and nine credit specialists who provide services to the Funds. The Special Committee noted that the investment adviser's municipal bond team affords the investment adviser extensive in-house research capabilities in addition to the other resources available to the investment adviser. The Special Committee also took into account the time and attention to be devoted by senior management to the Funds and the other funds in the complex. The Special Committee evaluated the level of skill required to manage the Funds and concluded that the human resources available at the investment adviser were appropriate to fulfill effectively its duties on behalf of the Funds.

In its review of comparative information with respect to each Fund's investment performance, the Special Committee concluded that each Fund has performed within a range that the Special Committee deemed

competitive. With respect to its review of investment advisory fees, the Special Committee concluded that the fees paid by each Fund are within the range of those paid by comparable funds within the mutual fund industry. In reviewing the information regarding the expense ratio of each Fund, the Special Committee concluded that each Fund's expense ratio is within a range it deemed to be competitive in comparison with comparable funds within the mutual fund industry.

In addition to the factors mentioned above, the Special Committee reviewed the level of the investment adviser's profits in providing investment management services for each Fund and for all Eaton Vance Funds as a group. The Special Committee also reviewed the level of profits of Eaton Vance and its affiliates in providing administration services for each Fund and for all Eaton Vance Funds as a group. The Special Committee also considered a contractual waiver of advisory fees for the first eight year's of each Fund's operations. In addition, the Special Committee considered the fiduciary duty assumed by the investment adviser in connection with the services rendered to each Fund and the business reputation of the investment adviser and its financial resources. The Trustees concluded that in light of the services rendered, the profits realized by the investment adviser are not unreasonable. The Special Committee also considered the fact that the Fund is not continuously offered and concluded that, in light of the level of the investment adviser's profits with respect to the Fund, the implementation of breakpoints is not appropriate.

The Special Committee did not consider any single factor as controlling in determining whether or not to renew the investment advisory agreements. Nor are the items described herein all the matters considered by the Special Committee. In assessing the information provided by Eaton Vance and its affiliates, the Special Committee also took into consideration the benefits to shareholders of investing in a fund that is a part of a large family of funds which provides a large variety of shareholder services.

Based on its consideration of the foregoing factors and conclusions, and such other factors and conclusions as it deemed relevant, and assisted by independent counsel, the Special Committee concluded that the renewal of the investment advisory agreements, including the fee structures (described herein), is in the interests of shareholders.

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 September 30, 2004 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.
