    Commodity Futures Trading Commission Registration. The Commodity Futures Trading Commission (“CFTC”) has adopted regulations that subject registered investment companies and advisers to regulation by the CFTC if a fund invests more than a prescribed level of its assets in certain CFTC-regulated instruments (including futures, certain options and swap agreements) or markets itself as providing investment exposure to such instruments. The investment adviser has claimed an exclusion from the definition of “commodity pool operator” under the Commodity Exchange Act with respect to its management of each Fund. Accordingly, neither the Funds nor the adviser with respect to the operation of the Funds is subject to CFTC regulation. Because of its management of other strategies, the Funds' adviser is registered with the CFTC as a commodity pool operator. The adviser is also registered as a commodity trading advisor.
    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.

    Past performance is no guarantee of future results. Returns are historical and are calculated net of management fees and other expenses by determining the percentage change in net asset value (NAV) or market price (as applicable) with all distributions reinvested in accordance with the Fund’s Dividend Reinvestment Plan. Furthermore, returns do not reflect the deduction of taxes that shareholders may have to pay on Fund distributions or upon the sale of Fund shares. Performance at market price will differ from performance at NAV due to variations in the Fund’s market price versus NAV, which may reflect factors such as fluctuations in supply and demand for Fund shares, changes in Fund distributions, shifting market expectations for the Fund’s future returns and distribution rates, and other considerations affecting the trading prices of closed-end funds. Investment return and principal value will fluctuate so that shares, when sold, may be worth more or less than their original cost. Performance for periods less than or equal to 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 eatonvance.com.

    1 For purposes of the Fund’s rating restrictions, ratings are based on Moody’s Investors Service, Inc. (“Moody’s”), S&P Global Ratings (“S&P”) or Fitch Ratings (“Fitch”), as applicable. If securities are rated differently by the ratings agencies, the highest rating is applied. Ratings, which are subject to change, apply to the creditworthiness of the issuers of the underlying securities and not to the Fund or its shares. Credit ratings measure the quality of a bond based on the issuer’s creditworthiness, with ratings ranging from AAA, being the highest, to D, being the lowest based on S&P’s measures. Ratings of BBB or higher by S&P or Fitch (Baa or higher by Moody’s) are considered to be investment-grade quality. Credit ratings are based largely on the ratings agency’s analysis at the time of rating. The rating assigned to any particular security is not necessarily a reflection of the issuer’s current financial condition and 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. Holdings designated as “Not Rated” (if any) are not rated by the national ratings agencies stated above.
    2 The chart includes the municipal bonds held by a trust that issues residual interest bonds, consistent with the Portfolio of Investments.

    1 Bloomberg Municipal Bond Index is an unmanaged index of municipal bonds traded in the U.S. 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 shares of the Fund often trade at a discount or premium to their net asset value. The discount or premium may vary over time and may be higher or lower than what is quoted in this report. For up-to-date premium/discount information, please refer to https://funds.eatonvance.com/closed-end-fund-prices.php.
    4 The Distribution Rate is calculated by dividing the Fund’s last regular distribution paid per share in the period (annualized) by the Fund’s NAV or market price (the price at which the Fund is traded on the exchange) at the end of the period. A Fund’s distributions in any period may be more or less than the net return earned by the Fund on its investments and should not be used as a measure of performance or confused with “yield” or “income.”
    The Fund has adopted a policy to pay common shareholders a stable monthly distribution. A portion of the Fund’s distributions may be subject to the U.S. federal alternative minimum tax. In an effort to maintain a stable distribution amount, the Fund may pay distributions consisting of amounts characterized for U.S. federal income tax purposes as exempt-interest dividends, ordinary dividends (including qualified dividends), capital gain distributions and nondividend distributions, also known as return of capital distributions. A nondividend or return of capital distribution results from a Fund distributing more than its net investment income and net realized capital gain for a given tax period and may represent a return of some or all of the money that an investor invested in the Fund’s shares, which, like other distributions, can cause the Fund’s NAV to erode. There is no assurance that the Fund will always be able to pay distributions of a particular size.
    With each distribution, the Fund issues a notice to shareholders and a press release containing information about the amount and sources of the distribution and related information. Notices and press releases for the last 24 months are available on our website https://www.
    eatonvance.com/resources/closed-end-fund-distribution-notices-19a.html. The amounts and sources of distributions are only estimates and are not provided for tax reporting purposes. The U.S. federal income tax character of distributions paid to a shareholder is reported on IRS Form 1099-DIV, which is provided to shareholders shortly after the end of each calendar year.
    The amount of the Fund’s distributions is determined by the investment adviser based on its current assessment of the Fund’s long-term return potential. Fund distributions may be affected by numerous factors including changes in Fund performance, the cost of financing for Funds that employ leverage, portfolio holdings, realized and projected returns, and other factors. As portfolio and market conditions change, the rate of distributions paid by the Fund could change. Shareholders should not assume that the source of any distribution from the Fund is net income or profit.
    Taxable-equivalent distributions are calculated using a 40.8% U.S. federal income tax rate, which reflects the maximum U.S. federal tax
      rate of 37% plus the 3.8% U.S. federal Medicare surtax. Where applicable, the calculation also includes the highest individual U.S. state income tax rate for residents of the state for which a Fund’s income is designed to be exempt. Local income taxes and other applicable taxes are not considered in the calculation.
    5 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 at period end as a percentage of Fund net assets plus Floating Rate Notes.
      Fund profiles subject to change due to active management.

    1  Significant Accounting Policies
    Eaton Vance Municipal Bond Fund (Municipal Fund), Eaton Vance California Municipal Bond Fund (California Fund) and Eaton Vance New York Municipal Bond Fund (New York 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). New York Fund is a non-diversified, closed-end management investment company. Municipal Fund and California Fund are diversified closed-end management investment companies. The Funds' investment objective is to provide current income exempt from regular federal income tax and, in state specific funds, taxes in their specified state and city (if any).
    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 (U.S. GAAP). Each Fund is an investment company and follows accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946.
    A  Investment Valuation—The following methodologies are used to determine the market value or fair value of investments.
    Debt Obligations. Debt obligations 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 ask prices, broker/dealer quotations, prices or yields of securities with similar characteristics, interest rates, anticipated prepayments, 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 debt obligations purchased with a remaining maturity of sixty days or less for which a valuation from a third party pricing service is not readily available may be valued at amortized cost, which approximates fair value.
    Fair Valuation. In connection with Rule 2a-5 of the 1940 Act, the Trustees have designated a Fund’s investment adviser as its valuation designee. Investments for which valuations or market quotations are not readily available or are deemed unreliable are valued by the investment adviser, as valuation designee, at fair value using methods that most fairly reflect the security’s “fair value”, which is the amount that a 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 companies or 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 company’s or entity’s financial statements, 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 non-taxable municipal securities, which are exempt from regular federal income tax when received by each Fund, as exempt-interest dividends. The portion of such interest, if any, earned on private activity bonds issued after August 7, 1986, may be considered a tax preference item to shareholders.
    As of March 31, 2025, 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  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.
    E  Use of Estimates—The preparation of the financial statements in conformity with U.S. GAAP 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.
    F  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, upon request by the shareholder, 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

    Notes to Financial Statements (Unaudited) — continued

    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.
    G  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 for cash to a Special-Purpose Vehicle (the SPV), (which is generally organized as a trust), while at the same time, buying a residual interest in the assets and cash flows of the SPV. The bond is deposited into the SPV with the same CUSIP number as the bond sold to the SPV 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 Bond held by the SPV transferred to the Fund, thereby terminating the SPV. Should the Fund exercise such right, it would generally pay the SPV 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 SPV for redemption at par at each reset date. Accordingly, the fair value of the payable for floating rate notes issued approximates its carrying value. If measured at fair value, the payable for floating rate notes would have been considered as Level 2 in the fair value hierarchy (see Note 6) at March 31, 2025. Interest expense related to a Fund’s 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 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. At March 31, 2025, 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 $317,222,974 $ 94,677,179 $77,048,474
    Interest Rate or Range of Interest Rates (%) 2.87 - 3.27 2.91 - 3.20 2.90 - 3.07
    Collateral for Floating Rate Notes Outstanding $415,843,713 $123,430,491 $99,774,100
    For the six months ended March 31, 2025, the Funds’ average settled Floating Rate Notes outstanding and the average interest rate (annualized) including fees were as follows:
      Municipal
    Fund
    California
    Fund
    New York
    Fund
    Average Floating Rate Notes Outstanding $323,520,467 $ 85,587,967 $85,944,863
    Average Interest Rate        3.46%        3.63%       3.46%
    In certain circumstances, the Funds may enter into shortfall and forbearance agreements with brokers by which a Fund agrees to reimburse the broker 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, 2025.
    The Funds may also purchase residual interest bonds 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. Effective August 19, 2022, the Funds began operating under Rule 18f-4 under the 1940 Act, which, among other things, governs the use of derivative investments and certain financing transactions by registered investment companies. Consistent with Rule 18f-4, the Funds may treat their investments in residual interest bonds and similar financing transactions as subject to the asset coverage requirements of Section 18 of the 1940 Act, or as derivatives transactions subject to the Funds’ value-at-risk (VaR)-based limits on leverage risk. Effective October 11, 2023, the Funds have opted to treat such investments as derivatives transactions. The Funds may change this approach at any time. Residual interest bonds held by the Funds are securities exempt from registration under Rule 144A of the Securities Act of 1933.

    H  When-Issued Securities and Delayed Delivery Transactions—The Funds may purchase 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 cash and/or 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. Such security purchases are subject to the risk that when delivered they will be worth less than the agreed upon payment price. Losses may also arise if the counterparty does not perform under the contract.
    I  Segment Reporting—During this reporting period, the Funds adopted FASB Accounting Standards Update No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (ASU 2023-07), which requires incremental disclosures related to a public entity’s reportable segments. Each Fund operates as a single reportable segment, an investment company whose investment objective is included in Note 1. In connection with the adoption of ASU 2023-07, the Funds' President acts as each Fund's Chief Operating Decision Maker (CODM), who is responsible for assessing the performance of each Fund's single segment and deciding how to allocate the segment’s resources. To perform this function, the CODM reviews the information in the Funds' financial statements.
    J  Interim Financial Statements—The interim financial statements relating to March 31, 2025 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 and Income Tax Information
    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. Distributions are recorded on the ex-dividend date. Distributions to shareholders are determined in accordance with income tax regulations, which may differ from U.S. GAAP. As required by U.S. GAAP, only distributions in excess of tax basis earnings and profits are 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. 
    Distributions in any year may include a return of capital component. For the six months ended March 31, 2025, the amount of distributions estimated to be a tax return of capital were approximately $4,816,000, $1,878,000 and $1,178,000 for Municipal Fund, California Fund and New York Fund, respectively. The final determination of tax characteristics of a Fund’s distributions will occur at the end of the year, at which time it will be reported to the  shareholders.
    At September 30, 2024, the following Funds, for federal income tax purposes, had deferred capital losses which would 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 would 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 deferred capital losses are treated as arising on the first day of a Fund’s next taxable year and retain the same short-term or long-term character as when originally deferred. The amounts of the deferred capital losses are as follows:
      Municipal
    Fund
    California
    Fund
    New York
    Fund
    Deferred capital losses:      
    Short-term $66,088,246 $21,951,636 $16,071,710
    Long-term $32,714,878 $30,292,386 $19,337,344
    The cost and unrealized appreciation (depreciation) of investments of each Fund at March 31, 2025, as determined on a federal income tax basis, were as follows:
      Municipal
    Fund
    California
    Fund
    New York
    Fund
    Aggregate cost $ 571,574,028 $255,608,916 $185,037,548
    Gross unrealized appreciation $ 17,880,925 $ 3,757,777 $ 2,251,777
    Gross unrealized depreciation (12,438,930) (9,682,004) (8,628,904)
    Net unrealized appreciation (depreciation) $ 5,441,995 $ (5,924,227) $ (6,377,127)

    3  Investment Adviser Fee and Other Transactions with Affiliates
    The investment adviser fee is earned by Eaton Vance Management (EVM), an indirect, wholly-owned subsidiary of Morgan Stanley, as compensation for investment advisory services rendered to each Fund. The investment adviser fee is computed at an annual rate of 0.60% of each Fund’s average weekly gross assets and is payable monthly. Gross assets of a Fund are calculated by deducting accrued liabilities of the Fund except (i) the principal amount of any indebtedness for money borrowed, including debt securities issued by the Fund and the amount of floating-rate notes included as a liability in the Fund’s Statement of Assets and Liabilities of up to $801,875,000 for Municipal Fund, $228,750,000 for California Fund and $165,000,000 for New York Fund, and (ii) the amount of any outstanding preferred shares issued by the Fund. EVM also serves as the administrator of each Fund, but receives no compensation. For the six months ended March 31, 2025, the investment adviser fees were as follows:
      Municipal
    Fund
    California
    Fund
    New York
    Fund
    Investment Adviser Fee $2,843,526 $1,003,595 $824,776
    Trustees and officers of the Funds who are members of EVM’s organization receive remuneration for their services to the Funds out of the investment adviser fee. Trustees of the Funds who are not affiliated with EVM 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. 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, 2025 were as follows:
      Municipal
    Fund
    California
    Fund
    New York
    Fund
    Purchases $ 68,426,617 $112,068,438 $31,776,012
    Sales $115,216,483 $ 91,785,263 $42,609,238
    5  Common Shares of Beneficial Interest
    The Funds may issue common shares pursuant to their dividend reinvestment plans. There were no common shares issued by the Funds for the six months ended March 31, 2025 and the year ended September 30, 2024.
    In November 2013, the Board of Trustees initially approved a share repurchase program for the Funds. Pursuant to the reauthorization of the share repurchase program by the Board of Trustees in March 2019, each Fund is authorized to repurchase up to 10% of its common shares outstanding as of the last day of the prior calendar year at market prices when shares are trading at a discount to net asset value (NAV). The share repurchase program does not obligate a Fund to purchase a specific amount of shares. There were no repurchases of common shares by the Funds for the six months ended March 31, 2025 and the year ended September 30, 2024.
    On May 6, 2024, Municipal Fund’s Board of Trustees (the “Board”) authorized a cash tender offer (the “Firm Tender Offer”) by Municipal Fund of up to 20% of its outstanding common shares at a price per share equal to 98% of Municipal Fund’s net asset value (“NAV”) per share as of the close of regular trading on the New York Stock Exchange (“NYSE”) on the date the Firm Tender Offer expires. On June 7, 2024, Municipal Fund commenced a cash tender offer for up to 14,230,637 of its outstanding shares. The tender offer expired at 5:00 p.m. Eastern Time on July 9, 2024. The number of properly tendered shares that were purchased was 14,230,637. The purchase price of the properly tendered shares was equal to $11.0913 per share for an aggregate purchase price of $157,836,264.
    The Board also authorized two conditional cash tender offers, to follow the Firm Tender Offer, for up to 5% of Municipal Fund’s then-outstanding common shares at 98% of NAV per share as of the close of regular trading on the NYSE on the date the tender offer expires, provided certain conditions are met. If Municipal Fund’s common shares were to trade at an average discount to NAV of more than 7.5% (based upon the average of the difference between its volume-weighted average market price and NAV each business day during a four-month measurement period, as measured at the close of the period), the condition for a conditional cash tender offer would be met.
    The four-month measurement period for the Initial Conditional Tender Offer was July 9, 2024 through November 8, 2024, during which the condition for the Initial Conditional Tender Offer was met. On December 10, 2024, Municipal Fund commenced a cash tender offer for up to 2,846,127 of its outstanding common shares. The tender offer expired at 5:00 p.m. Eastern Time on January 10, 2025. The number of properly tendered shares that were purchased was 2,846,127. The purchase price of the properly tendered shares was equal to $10.7664 per share for an aggregate purchase price of $30,642,542.

    On January 14, 2025, Municipal Fund announced the four-month measurement period for the Second Conditional Tender Offer, beginning March 10, 2025 through July 9, 2025. If the condition for the Second Conditional Offer is met, Municipal Fund will conduct the Second Conditional Tender Offer within 20 business days after the close of the measurement period.
    At March 31, 2025, according to the filings made on Schedule 13D and 13G pursuant to Sections 13(d) and 13(g) of the Securities Exchange Act of 1934, as amended, one entity owned 14.4% of Municipal Fund's common shares, three affiliated entities and two affiliated entities each owned more than 10% of California Fund's common shares aggregating 29.6%, and three affiliated entities and two affiliated entities each owned more than 10% of New York Fund's common shares aggregating 34.1%.
    6  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, 2025, the hierarchy of inputs used in valuing the Funds' investments, which are carried at fair value, were as follows:
    Municipal Fund        
    Asset Description  Level 1 Level 2 Level 3 Total
    Tax-Exempt Municipal Obligations $  — $ 893,886,690 $  — $ 893,886,690

    IMPORTANT NOTICES

    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. Equiniti Trust Company, LLC ("EQ"), the closed-end funds transfer agent, or your financial intermediary, may household the mailing of your documents indefinitely unless you instruct EQ, or your financial intermediary, otherwise. If you would prefer that your Eaton Vance documents not be householded, please contact EQ or your financial intermediary. Your instructions that householding not apply to delivery of your Eaton Vance documents will typically be effective within 30 days of receipt by EQ or your financial intermediary.
    Portfolio Holdings. Each Eaton Vance Fund and its underlying Portfolio(s) (if applicable) files a schedule of portfolio holdings on Part F to Form N-PORT with the SEC. Certain information filed on Form N-PORT may be viewed 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.
    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. You may also access proxy voting information for the Eaton Vance Funds or their underlying Portfolios at www.eatonvance.com/
    proxyvoting.
    Share Repurchase Program. The Funds' Boards of Trustees have approved a share repurchase program authorizing each Fund to repurchase up to 10% of its common shares outstanding as of the last day of the prior calendar year in open-market transactions at a discount to net asset value. The repurchase program does not obligate a Fund to purchase a specific amount of shares. The Funds' repurchase activity, including the number of shares purchased, average price and average discount to net asset value, is disclosed in the Funds' annual and semi-annual reports to shareholders.
    Additional Notice to Shareholders. If applicable, a Fund may also redeem or purchase its outstanding preferred shares in order to maintain compliance with regulatory requirements, borrowing or rating agency requirements or for other purposes as it deems appropriate or necessary.
    Closed-End Fund Information. Eaton Vance closed-end funds make fund performance data and certain information about portfolio characteristics available on the Eaton Vance website shortly after the end of each month. Other information about the funds is available on the website. The funds’ net asset value per share is readily accessible on the Eaton Vance website. Portfolio holdings for the most recent month-end are also posted to the website approximately 30 days following the end of the month. This information is available at www.eatonvance.com on the fund information pages under “Closed-End Funds & Term Trusts.”

If Municipal Bond Fund’s common shares were to trade at an average discount to NAV of more than 7.5% (based upon the average of the difference between its volume-weighted average market price and NAV each business day during a four-month measurement period, as measured at the close of the period), the condition for a conditional cash tender offer would be met.
