See Endnotes and Additional Disclosures in this report.

Past performance is no guarantee of future results. Returns are historical and are calculated by determining the percentage change in net asset value (NAV) or market price (as applicable) with all distributions reinvested. Fund performance at market price will differ from its results at NAV due to factors such as changing perceptions about the Fund, market conditions, fluctuations in supply and demand for Fund shares, or changes in Fund distributions. Investment return and principal value will fluctuate so that shares, when sold, may be worth more or less than their original cost. Performance less than one year is cumulative. Performance is for the stated time period only; due to market volatility, current Fund performance may be lower or higher than the quoted return. For performance as of the most recent month end, please refer to www.eatonvance.com.

Endnotes and Additional Disclosures


¹	Barclays Capital Long (22+) Municipal Bond Index is an unmanaged index of municipal bonds traded in the U.S. with maturities of 22 years or more. Unless otherwise stated, index returns do not reflect the effect of any applicable sales charges, commissions, expenses, taxes or leverage, as applicable. It is not possible to invest directly in an index.

²	Performance results reflect the effects of leverage.

³	The Distribution Rate is based on the Fund’s last regular distribution per share in the period (annualized) divided by the Fund’s NAV or market price at the end of the period. The Fund’s distributions may be composed of ordinary income, tax-exempt income, net realized capital gains and return of capital. Taxable-equivalent performance is based on the highest combined federal and state income tax rates, where applicable. Lower tax rates would result in lower tax-equivalent performance. Actual tax rates will vary depending on your income, exemptions and deductions. Rates do not include local taxes. Subsequent distributions declared, but not reflected in the Fund Profile, reflect a reduction of the monthly distribution for California Municipal Bond Fund.

⁴	Fund employs RIB financing. The leverage created by RIB investments provides an opportunity for increased income but, at the same time, creates special risks (including the likelihood of greater price volatility). The cost of leverage rises and falls with changes in short-term interest rates. See "Floating Rate Notes Issued in Conjunction with Securities Held" in the notes to the financial statements for more information about RIB financing. RIB leverage represents the amount of Floating Rate Notes outstanding as of period end as a percentage of Fund net assets plus Floating Rate Notes.

⁵	Ratings are based on Moody’s, S&P or Fitch, as applicable. Credit ratings are based largely on the rating agency’s investment analysis at the time of rating and the rating assigned to any particular security is not necessarily a reflection of the issuer’s current financial condition. The rating assigned to a security by a rating agency does not necessarily reflect its assessment of the volatility of a security’s market value or of the liquidity of an investment in the security. If securities are rated differently by the rating agencies, the higher rating is applied.

	Fund profile subject to change due to active management.

The aggregate percentage insured by an individual financial institution ranged from 1.1% to 20.2% of total investments.


⁽¹⁾		Security represents the municipal bond held by a trust that issues residual interest bonds (see Note 1H).

⁽²⁾		Defaulted security. Issuer has defaulted on the payment of interest or has filed for bankruptcy.

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, 2012, 62.7% 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 2.0% to 26.2% of total investments.

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, 2012, 54.0% 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 1.0% to 19.2% of total investments.


⁽¹⁾		Security represents the municipal bond held by a trust that issues residual interest bonds (see Note 1H).

⁽²⁾		When-issued security.

⁽³⁾		Security (or a portion thereof) has been segregated to cover payable for when-issued securities.

⁽⁴⁾		Security (or a portion thereof) has been pledged as collateral for residual interest bond transactions. The aggregate value of such collateral is $421,860.

1 Significant Accounting Policies

Eaton Vance Municipal Bond Fund, Eaton Vance California Municipal Bond Fund and Eaton Vance New York Municipal Bond Fund, (each individually referred to as the Fund, and collectively, the Funds), are Massachusetts business trusts registered under the Investment Company Act of 1940, as amended (the 1940 Act), as non-diversified, closed-end management investment companies. The Funds seek to provide current income exempt from regular federal income tax, including alternative minimum tax, and, in state specific funds, taxes in its specified state.

The following is a summary of significant accounting policies of the Funds. The policies are in conformity with accounting principles generally accepted in the United States of America.

A Investment Valuation — Debt obligations (including short-term obligations with a remaining maturity of more than sixty days) are generally valued on the basis of valuations provided by third party pricing services, as derived from such services’ pricing models. Inputs to the models may include, but are not limited to, reported trades, executable bid and asked prices, broker/dealer quotations, prices or yields of securities with similar characteristics, benchmark curves or information pertaining to the issuer, as well as industry and economic events. The pricing services may use a matrix approach, which considers information regarding securities with similar characteristics to determine the valuation for a security. Short-term obligations purchased with a remaining maturity of sixty days or less are generally valued at amortized cost, which approximates market value. Financial futures contracts are valued at the closing settlement price established by the board of trade or exchange on which they are traded. Interest rate swaps are normally valued using valuations provided by a third party pricing service. Such pricing service valuations are based on the present value of fixed and projected floating rate cash flows over the term of the swap contract. Future cash flows are discounted to their present value using swap rates provided by electronic data services or by broker/dealers. Investments for which valuations or market quotations are not readily available or are deemed unreliable are valued at fair value using methods determined in good faith by or at the direction of the Trustees of a Fund in a manner that fairly reflects the security’s value, or the amount that the Fund might reasonably expect to receive for the security upon its current sale in the ordinary course. Each such determination is based on a consideration of relevant factors, which are likely to vary from one pricing context to another. These factors may include, but are not limited to, the type of security, the existence of any contractual restrictions on the security’s disposition, the price and extent of public trading in similar securities of the issuer or of comparable entities, quotations or relevant information obtained from broker/dealers or other market participants, information obtained from the issuer, analysts, and/or the appropriate stock exchange (for exchange-traded securities), an analysis of the entity’s financial condition, and an evaluation of the forces that influence the issuer and the market(s) in which the security is purchased and sold.

B Investment Transactions and Related Income — Investment transactions for financial statement purposes are accounted for on a trade date basis. Realized gains and losses on investments sold are determined on the basis of identified cost. Interest income is recorded on the basis of interest accrued, adjusted for amortization of premium or accretion of 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 substantially all of its taxable, if any, and tax-exempt net investment income, and all or substantially all of its net realized capital gains. Accordingly, no provision for federal income or excise tax is necessary. 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 tax when received by each Fund, as exempt-interest dividends.

At September 30, 2011, the following Funds, for federal income tax purposes, had capital loss carryforwards which will reduce the respective Fund’s taxable income arising from future net realized gains on investment transactions, 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 carryforwards are as follows:


Expiration Date	Municipal Fund		California Fund		New York Fund


September 30, 2012	$	314,751	$	—	$	—
September 30, 2013		—		—		125,998
September 30, 2015		31,250		—		—
September 30, 2016		6,857,645		533,889		—
September 30, 2017		18,034,628		4,562,453		7,946,914
September 30, 2018		56,183,712		23,169,615		8,909,352
September 30, 2019		16,458,561		7,665,268		6,463,209



	$	97,880,547	$	35,931,225	$	23,445,473

In addition, such capital loss carryforwards cannot be utilized prior to the utilization of new capital losses, if any, created after September 30, 2011.

March 31, 2012

Notes to Financial Statements (Unaudited) — continued

Additionally, at September 30, 2011, the Municipal Fund, California Fund and New York Fund had net capital losses of $37,513,142, $19,463,688 and $8,695,243, respectively, attributable to security transactions incurred after October 31, 2010. These net capital losses are treated as arising on the first day of the Funds’ taxable year ending September 30, 2012.

As of March 31, 2012, the Funds had no uncertain tax positions that would require financial statement recognition, de-recognition, or disclosure. Each Fund files a U.S. federal income tax return annually after its fiscal year-end, which is subject to examination by the Internal Revenue Service for a period of three years from the date of filing.

D Expense Reduction — State Street Bank and Trust Company (SSBT) serves as custodian of the Funds. Pursuant to the respective custodian agreements, SSBT receives a fee reduced by credits, which are determined based on the average daily cash balance each Fund maintains with SSBT. All credit balances, if any, used to reduce each Fund’s custodian fees are reported as a reduction of expenses in the Statements of Operations.

E Legal Fees — Legal fees and other related expenses incurred as part of negotiations of the terms and requirement of capital infusions, or that are expected to result in the restructuring of, or a plan of reorganization for, an investment are recorded as realized losses. Ongoing expenditures to protect or enhance an investment are treated as operating expenses.

F Use of Estimates — The preparation of the 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.

G 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. Under Massachusetts law, if certain conditions prevail, shareholders of a Massachusetts business trust (such as a Fund) could be deemed to have personal liability for the obligations of the Fund. However, each Fund’s Declaration of Trust contains an express disclaimer of liability on the part of Fund shareholders and the By-laws provide that the Fund shall assume the defense on behalf of any Fund shareholders. Moreover, the By-laws also provide for indemnification out of Fund property of any shareholder held personally liable solely by reason of being or having been a shareholder for all loss or expense arising from such liability. 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.

H Floating Rate Notes Issued in Conjunction with Securities Held — The Funds may invest in residual interest bonds, also referred to as inverse floating rate securities, whereby a Fund may sell a variable or fixed rate bond to a broker for cash. At the same time, the Fund buys a residual interest in the assets and cash flows of a Special-Purpose Vehicle (the SPV), (which is generally organized as a trust), set up by the broker. The broker deposits a bond into the SPV with the same CUSIP number as the bond sold to the broker by the Fund, and which may have been, but is not required to be, the bond purchased from the Fund (the Bond). The SPV also issues floating rate notes (Floating Rate Notes) which are sold to third-parties. The residual interest bond held by a Fund gives the Fund the right (1) to cause the holders of the Floating Rate Notes to generally tender their notes at par, and (2) to have the broker transfer the Bond held by the SPV to the Fund, thereby terminating the SPV. Should the Fund exercise such right, it would generally pay the broker the par amount due on the Floating Rate Notes and exchange the residual interest bond for the underlying Bond. Pursuant to generally accepted accounting principles for transfers and servicing of financial assets and extinguishment of liabilities, the Funds account for the transaction described above as a secured borrowing by including the Bond in their Portfolio of Investments and the Floating Rate Notes as a liability under the caption “Payable for floating rate notes issued” in their Statement of Assets and Liabilities. The Floating Rate Notes have interest rates that generally reset weekly and their holders have the option to tender their notes to the broker for redemption at par at each reset date. Accordingly, the fair value of the payable for floating rate notes issued approximates its carrying value. Interest expense related to the Funds’ liability with respect to Floating Rate Notes is recorded as incurred. The SPV may be terminated by the Fund, as noted above, or by the broker upon the occurrence of certain termination events as defined in the trust agreement, such as a downgrade in the credit quality of the underlying Bond, bankruptcy of or payment failure by the issuer of the underlying Bond, the inability to remarket Floating Rate Notes that have been tendered due to insufficient buyers in the market, or the failure by the SPV to obtain renewal of the liquidity agreement under which liquidity support is provided for the Floating Rate Notes up to one year. Structuring fees paid to the liquidity provider upon the creation of an SPV have been recorded as debt issuance costs and are being amortized as interest expense to the expected maturity of the related trust. Unamortized structuring fees related to a terminated SPV are recorded as a realized loss on extinguishment of debt. At March 31, 2012, the amounts of the Funds’ Floating Rate Notes and related interest rates and collateral were as follows:


	Municipal Fund		California Fund		New York Fund


Floating Rate Notes Outstanding	$	615,555,000	$	171,840,000	$	136,000,000
Interest Rate or Range of Interest Rates (%)		0.19 - 0.49		0.19 - 0.29		0.18 - 0.24
Collateral for Floating Rate Notes Outstanding	$	703,465,907	$	196,548,754	$	158,751,589

Eaton Vance

Municipal Bond Funds

March 31, 2012

Notes to Financial Statements (Unaudited) — continued

For the six months ended March 31, 2012, the Funds’ average Floating Rate Notes outstanding and the average interest rate (annualized) including fees and amortization of deferred debt issuance costs were as follows:


	Municipal Fund			California Fund			New York Fund


Average Floating Rate Notes Outstanding	$	617,305,219		$	191,603,005		$	141,481,667
Average Interest Rate		0.65	%		0.63	%		0.63	%

The Funds may enter into shortfall and forbearance agreements with the broker by which a Fund agrees to reimburse the broker, in certain circumstances, for the difference between the liquidation value of the Bond held by the SPV and the liquidation value of the Floating Rate Notes, as well as any shortfalls in interest cash flows. The Funds had no shortfalls as of March 31, 2012.

The Funds may also purchase residual interest bonds from brokers in a secondary market transaction without first owning the underlying bond. Such transactions are not required to be treated as secured borrowings. Shortfall agreements, if any, related to residual interest bonds purchased in a secondary market transaction are disclosed in the Portfolio of Investments.

The Funds’ investment policies and restrictions expressly permit investments in residual interest bonds. Such bonds typically offer the potential for yields exceeding the yields available on fixed rate bonds with comparable credit quality and maturity. These securities tend to underperform the market for fixed rate bonds in a rising long-term interest rate environment, but tend to outperform the market for fixed rate bonds when long-term interest rates decline. The value and income of residual interest bonds are generally more volatile than that of a fixed rate bond. The Funds’ investment policies do not allow the Funds to borrow money except as permitted by the 1940 Act. Management believes that the Funds’ restrictions on borrowing money and issuing senior securities (other than as specifically permitted) do not apply to Floating Rate Notes issued by the SPV and included as a liability in the Funds’ Statement of Assets and Liabilities. As secured indebtedness issued by an SPV, Floating Rate Notes are distinct from the borrowings and senior securities to which the Funds’ restrictions apply. Residual interest bonds held by the Funds are securities exempt from registration under Rule 144A of the Securities Act of 1933.

I Financial Futures Contracts — Upon entering into a financial futures contract, a Fund is required to deposit with the broker, either in cash or securities, an amount equal to a certain percentage of the purchase price (initial margin). Subsequent payments, known as variation margin, are made or received by the Fund each business day, depending on the daily fluctuations in the value of the underlying security, and are recorded as unrealized gains or losses by the Fund. Gains (losses) are realized upon the expiration or closing of the financial futures contracts. Should market conditions change unexpectedly, the Fund may not achieve the anticipated benefits of the financial futures contracts and may realize a loss. Futures contracts have minimal counterparty risk as they are exchange traded and the clearinghouse for the exchange is substituted as the counterparty, guaranteeing counterparty performance.

J Interest Rate Swaps — Pursuant to interest rate swap agreements, a Fund makes periodic payments at a fixed interest rate and, in exchange, receives payments based on the interest rate of a benchmark industry index. Payments received or made are recorded as realized gains or losses. During the term of the outstanding swap agreement, changes in the underlying value of the swap are recorded as unrealized gains or losses. The value of the swap is determined by changes in the relationship between two rates of interest. A Fund is exposed to credit loss in the event of non-performance by the swap counterparty. Risk may also arise from movements in interest rates.

K When-Issued Securities and Delayed Delivery Transactions — The Funds may purchase or sell securities on a delayed delivery or when-issued basis. Payment and delivery may take place after the customary settlement period for that security. At the time the transaction is negotiated, the price of the security that will be delivered is fixed. The Funds maintain security positions for these commitments such that sufficient liquid assets will be available to make payments upon settlement. Securities purchased on a delayed delivery or when-issued basis are marked-to-market daily and begin earning interest on settlement date. Losses may arise due to changes in the market value of the underlying securities or if the counterparty does not perform under the contract.

L Statement of Cash Flows — The cash amount shown in the Statement of Cash Flows of a Fund is the amount included in the Fund’s Statement of Assets and Liabilities and represents the cash on hand at its custodian and does not include any short-term investments.

M Interim Financial Statements — The interim financial statements relating to March 31, 2012 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 Distributions to Shareholders

Each Fund intends to make monthly distributions of net investment income to common shareholders. In addition, at least annually, each Fund intends to distribute all or substantially all of its net realized capital gains (reduced by available capital loss carryforwards from prior years, if any). Distributions are recorded on the ex-dividend date.

Eaton Vance

Municipal Bond Funds

March 31, 2012

Notes to Financial Statements (Unaudited) — continued

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. For tax purposes, distributions from short-term capital gains are considered to be from ordinary income.

3 Investment Adviser Fee and Other Transactions with Affiliates

The investment adviser fee is earned by Eaton Vance Management (EVM) as compensation for investment advisory services rendered to each Fund. The fee is computed at an annual rate of 0.65% of each Fund’s average weekly gross assets and is payable monthly. Average weekly gross assets include the principal amount of any indebtedness for money borrowed, including debt securities issued by a Fund. Pursuant to a fee reduction agreement with EVM, average weekly gross assets are calculated by adding to net assets the amount payable by the Fund to floating rate note holders, such adjustment being limited to the value of the Auction Preferred Shares (APS) outstanding prior to any APS redemptions by the Fund. EVM also serves as the administrator of each Fund, but receives no compensation. For the six months ended March 31, 2012, the investment adviser fees were as follows:


	Municipal Fund		California Fund		New York Fund


Investment Adviser Fee	$	4,839,381	$	1,481,817	$	1,157,066

Except for Trustees of the Funds who are not members of EVM’s organization, officers and Trustees receive remuneration for their services to the Funds out of the investment adviser fee. Trustees of the Funds who are not affiliated with the investment adviser may elect to defer receipt of all or a percentage of their annual fees in accordance with the terms of the Trustees Deferred Compensation Plan. For the six months ended March 31, 2012, no significant amounts have been deferred. Certain officers and Trustees of the Funds are officers of EVM.

4 Purchases and Sales of Investments

Purchases and sales of investments, other than short-term obligations, for the six months ended March 31, 2012 were as follows:


	Municipal Fund		California Fund		New York Fund


Purchases	$	174,352,587	$	71,019,716	$	22,516,095
Sales	$	182,867,480	$	90,266,775	$	23,742,180

5 Common Shares of Beneficial Interest

Common shares issued pursuant to the Funds’ dividend reinvestment plan for the six months ended March 31, 2012 and the year ended September 30, 2011 were as follows:


	Municipal Fund		California Fund		New York Fund


Six Months Ended March 31, 2012 (Unaudited)		14,119		9,232		12,737
Year Ended September 30, 2011		114,120		29,025		36,395

6 Federal Income Tax Basis of Investments

The cost and unrealized appreciation (depreciation) of investments of each Fund at March 31, 2012, as determined on a federal income tax basis, were as follows:


	Municipal Fund			California Fund			New York Fund


Aggregate cost	$	797,796,142		$	248,453,915		$	191,155,866



Gross unrealized appreciation	$	105,593,769		$	28,627,933		$	25,960,411
Gross unrealized depreciation		(29,619,874	)		(6,042,108	)		(1,190,798	)



Net unrealized appreciation	$	75,973,895		$	22,585,825		$	24,769,613

7 Overdraft Advances

Pursuant to the respective custodian agreements, SSBT may, in its discretion, advance funds to the Funds to make properly authorized payments. When such payments result in an overdraft, the Funds are obligated to repay SSBT at the current rate of interest charged by SSBT for secured loans (currently, a rate above the Federal Funds rate). This obligation is payable on demand to SSBT. SSBT has a lien on a Fund’s assets to the extent of any overdraft. At March 31, 2012, the California Fund and New York Fund had payments due to SSBT pursuant to the foregoing arrangement of $4,783,297 and $1,509,512, respectively.

8 Financial Instruments

The Funds may trade in financial instruments with off-balance sheet risk in the normal course of their investing activities. These financial instruments may include financial futures contracts and interest rate swaps 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 a Fund has in particular classes of financial instruments and do not necessarily represent the amounts potentially subject to risk. The measurement of the risks associated with these instruments is meaningful only when all related and offsetting transactions are considered.

A summary of obligations under these financial instruments at March 31, 2012 is as follows:


Futures Contracts
										Net

At March 31, 2012, the Funds had sufficient cash and/or securities to cover commitments under these contracts.

Each Fund is subject to interest rate risk in the normal course of pursuing its investment objective. Because the Funds hold fixed-rate bonds, the value of these bonds may decrease if interest rates rise. To hedge against this risk, the Municipal Fund and New York Fund entered into interest rate swap contracts. The Funds also purchase and sell U.S. Treasury futures contracts to hedge against changes in interest rates.

The fair values of open derivative instruments (not considered to be hedging instruments for accounting disclosure purposes) and whose primary underlying risk exposure is interest rate risk at March 31, 2012 were as follows:


	Municipal Fund			California Fund			New York Fund


Asset Derivative:
Futures Contracts	$	834,606	⁽¹⁾	$	766,807	⁽¹⁾	$	230,141	⁽¹⁾



Total	$	834,606		$	766,807		$	230,141


⁽¹⁾		Amount represents cumulative unrealized appreciation on futures contracts in the Futures Contracts table above. Only the current day’s variation margin on open futures contracts is reported within the Statement of Assets and Liabilities as Receivable or Payable for variation margin, as applicable.

9 Fair Value Measurements

Under generally accepted accounting principles for fair value measurements, a three-tier hierarchy to prioritize the assumptions, referred to as inputs, is used in valuation techniques to measure fair value. The three-tier hierarchy of inputs is summarized in the three broad levels listed below.


•	Level 1 – quoted prices in active markets for identical investments

•	Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.)

•	Level 3 – significant unobservable inputs (including a fund’s own assumptions in determining the fair value of investments)

In cases where the inputs used to measure fair value fall in different levels of the fair value hierarchy, the level disclosed is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

At March 31, 2012, the hierarchy of inputs used in valuing the Funds’ investments and open derivative instruments, which are carried at value, were as follows:


Municipal Fund
Asset Description	Level 1		Level 2		Level 3		Total


Tax-Exempt Investments	$	—	$	1,489,325,037	$	—	$	1,489,325,037



Total Investments	$	—	$	1,489,325,037	$	—	$	1,489,325,037



Futures Contracts	$	834,606	$	—	$	—	$	834,606



Total	$	834,606	$	1,489,325,037	$	—	$	1,490,159,643

The Funds held no investments or other financial instruments as of September 30, 2011 whose fair value was determined using Level 3 inputs. At March 31, 2012, the value of investments transferred between Level 1 and Level 2, if any, during the six months then ended was not significant.

Delivery of Shareholder Documents. The Securities and Exchange Commission (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 advisor, may household the mailing of your documents indefinitely unless you instruct Eaton Vance, or your financial advisor, 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 advisor. 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 advisor.

Portfolio Holdings. Each Eaton Vance Fund and its underlying Portfolio(s) (if applicable) will file a schedule of 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 at 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 and by accessing the SEC’s website at www.sec.gov.

Additional Notice to Shareholders. A Fund may purchase shares of its common stock in the open market when they trade at a discount to net asset value or at other times if a Fund determines such purchases are advisable. There can be no assurance that a Fund will take such action or that such purchases would reduce the discount.

Closed-End Fund Information. The Eaton Vance closed-end funds make certain quarterly fund performance data and information about portfolio characteristics (such as top holdings and asset allocation) available on the Eaton Vance website after the end of each calendar quarter-end. Certain month end fund performance data for the funds, including total returns, are posted to the website shortly after the end of each calendar month. Portfolio holdings for the most recent calendar quarter-end are also posted to the website approximately 30 days following the end of the quarter.

Item 6. Schedule of Investments

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. An independent proxy voting service (“Agent”), currently Institutional Shareholder Services, Inc., has been retained to assist in the voting of proxies through the provision of vote analysis, implementation and recordkeeping and disclosure services. The investment adviser will generally vote proxies through the Agent. The Agent is required to vote all proxies and/or refer them back to the investment adviser pursuant to the Policies. It is generally the policy of the investment adviser to vote in accordance with the recommendation of the Agent. The Agent shall refer to the investment adviser proxies relating to mergers and restructurings, and the disposition of assets, termination, liquidation and mergers contained in mutual fund proxies. The investment adviser will normally vote against anti-takeover measures and other proposals designed to limit the ability of shareholders to act on possible transactions, except in the case of closed-end management investment companies. The investment adviser generally supports management on social and environmental proposals. 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 or the economic effect on shareholders interests or the value of the portfolio holding is indeterminable or insignificant.

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 the personnel of the investment adviser identified in the Policies. If such personnel expects to

instruct the Agent to vote such proxies in a manner inconsistent with the guidelines of the Policies or the recommendation of the Agent, the personnel will consult with members of senior management of the investment adviser to determine if a material conflict of interests exists. If it is determined that a material 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.
