Important Note. Beginning on January 1, 2021, as permitted by regulations adopted by the Securities and Exchange Commission, paper copies of each Fund’s annual and semi-annual shareholder reports will no longer be sent by mail unless you specifically request paper copies of the reports. Instead, the reports will be made available on the Funds’ website(funds.eatonvance.com/closed-end-fund-and-term-trust-documents.php), and you will be notified by mail each time a report is posted and provided with a website address to access the report.

If you already elected to receive shareholder reports electronically, you will not be affected by this change and you need not take any action. If you hold shares at the Funds’ transfer agent, American Stock Transfer & Trust Company, LLC (“AST”), you may elect to receive shareholder reports and other communications from the Funds electronically by contacting AST.

If you own these shares through a financial intermediary, you must contact your financial intermediary or follow instructions included with this disclosure, if applicable, to elect to continue to receive paper copies of your shareholder reports.

Commodity Futures Trading Commission Registration.Effective December 31, 2012, the Commodity Futures Trading Commission (“CFTC”) adopted certain regulatory changes 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. 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.

Endnotes and Additional Disclosures

Bloomberg Barclays 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.

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. Forup-to-date premium/discount information, please refer tohttps://funds.eatonvance.com/closed-end-fund-prices.php.

⁴

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 comprised of amounts characterized for federal income tax purposes astax-exempt income, qualified andnon-qualified ordinary dividends, capital gains and nondividend distributions, also known as return of capital. The Fund will determine the federal income tax character of distributions paid to a shareholder after the end of the calendar year. This is reported on the IRS form1099-DIV and provided to the shareholder shortly after eachyear-end. For information about the tax character of distributions made in prior calendar years, please refer toPerformance-Tax Character of Distributions on the Fund’s webpage available at eatonvance.com. The Fund’s distributions are 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. Taxable-equivalent performance is based on the highest combined federal and state income tax rates, where applicable. Lower tax rates would result in lowertax-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 Fund Performance, reflect a reduction of the monthly distribution for California Municipal Bond Fund.

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.

⁶

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.

⁷	The chart includes the municipal bonds held by a trust that issues residual interest bonds, consistent with the Portfolio of Investments.

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), asnon-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 its 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.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 most fairly reflects 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, andtax-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 innon-taxable municipal obligations, 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, 2020, 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 fiscalyear-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 theBy-laws provide that the Fund shall assume, upon request by the shareholder, the defense on behalf of any Fund shareholders. Moreover, theBy-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.

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, 2020. 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. 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, 2020, 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	$	773,055,644	$	220,207,207	$	149,197,843

Interest Rate or Range of Interest Rates (%)		3.00 - 5.20		3.00 - 5.01		3.00 - 5.02

Collateral for Floating Rate Notes Outstanding	$	1,095,337,993	$	312,132,131	$	204,009,674

For the six months ended March 31, 2020, 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	$	794,924,208		$	226,173,279		$	157,476,995

Average Interest Rate		1.94	%		1.91	%		1.96	%

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, 2020.

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. 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.

H 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


		30

Notes to Financial Statements (Unaudited) — continued

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 aremarked-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.

I Interim Financial Statements — The interim financial statements relating to March 31, 2020 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 theex-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 topaid-in capital. For tax purposes, distributions from short-term capital gains are considered to be from ordinary income.

At September 30, 2019, 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	$	39,814,966	$	14,681,260	$	6,243,465

Long-term	$	4,675,998	$	19,951,719	$	2,402,322

Included in the amounts above are deferred capital losses as a result of the reorganizations during the year ended September 30, 2019 (see Note 7). Utilization of these deferred capital losses may be limited in accordance with certain income tax regulations. The amounts of the deferred capital losses are as follows:


	Municipal Fund		California Fund		New York Fund

Deferred capital losses from reorganizations:

Short-term	$	5,197,423	$	2,708,254	$	1,553,735

Long-term	$	4,675,998	$	2,346,701	$	449,772

The cost and unrealized appreciation (depreciation) of investments of each Fund at March 31, 2020, as determined on a federal income tax basis, were as follows:


	Municipal Fund			California Fund			New York Fund

Aggregate cost	$	883,935,804		$	271,104,315		$	211,919,071

Gross unrealized appreciation	$	135,473,487		$	29,993,619		$	17,869,655

Gross unrealized depreciation		(5,511,791	)		(93,824	)		(965,817	)

Net unrealized appreciation	$	129,961,696		$	29,899,795		$	16,903,838

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. Pursuant to the investment advisory agreement and a subsequent fee reduction agreement between each Fund and EVM, the fee is calculated at an annual rate of 0.60% of each Fund’s average weekly gross assets. The fee reductions cannot be terminated without the consent of a majority of Trustees and a majority of shareholders. 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 between each Fund and 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. The investment adviser fee is payable monthly. EVM also serves as the administrator of each Fund, but receives no compensation. For the six months ended March 31, 2020, the investment adviser fees were as follows:


	Municipal Fund		California Fund		New York Fund

Investment Adviser Fee	$	5,632,357	$	1,619,344	$	1,204,107

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. For the six months ended March 31, 2020, 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, 2020 were as follows:


	Municipal Fund		California Fund		New York Fund

Purchases	$	94,852,799	$	38,876,140	$	77,105,629

Sales	$	180,447,671	$	46,392,420	$	83,148,598

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, 2020 and the year ended September 30, 2019 pursuant to such plans.

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, 2020. During the year ended September 30, 2019, the number, cost (including brokerage commissions), average price per share and weighted average discount per share to NAV of common shares repurchased, were as follows:


	Year ended September 30, 2019
	Municipal Fund			California Fund

Common shares repurchased		1,326,880			387,540

Cost, including brokerage commissions, of common shares repurchased	$	16,221,641		$	4,211,453

Average price per share	$	12.23		$	10.87

Weighted average discount per share to NAV		9.45	%		12.17	%

On March 27, 2019, Municipal Fund announced that its Board of Trustees approved a cash tender offer for up to 10% of its outstanding common shares at a price equal to 98% of the Fund’s net asset value per share as of the close of regular trading on the New York Stock Exchange on the date the tender offer expires. On April 18, 2019, Municipal Fund commenced a cash tender offer for 8,969,613 of its outstanding shares. The tender offer expired at


		32

Eaton Vance

Municipal Bond Funds

March 31, 2020

Notes to Financial Statements (Unaudited) — continued

5:00 P.M. on May 17, 2019. In accordance with the terms and conditions of the tender offer, because the number of shares tendered exceeded the number of shares offered to purchase, Municipal Fund purchased shares from tendering shareholders on apro-rata basis (disregarding fractional shares). The purchase price of the properly tendered shares was equal to $13.374 per share for an aggregate purchase price of $119,959,604.

The Board of Trustees also authorized Municipal Fund to conduct two conditional cash tender offers, for up to 5% of Municipal Fund’s outstanding common shares at a price equal to 98% of Municipal Fund’s net asset value per share as of the close of regular trading on the New York Stock Exchange on the date the tender offer expires, to follow the initial tender offer, which expired May 17, 2019, provided certain conditions are met.

As of October 1, 2019, the terms of the first conditional tender offer were met. On November 14, 2019, Municipal Fund commenced a cash tender offer for up to 5% or 3,986,326 of its outstanding common shares at a price per share equal to 98% of Municipal Fund’s net asset value per share as of the close of regular trading on the New York Stock Exchange on the date the tender offer expires. The tender offer expired at 5:00 P.M. Eastern Time on December 13, 2019. In accordance with the terms and conditions of the first conditional tender offer, because the number of shares tendered exceeded the number of shares offered to purchase, Municipal Fund purchased shares from tendering shareholders on a pro-rata basis (disregarding fractional shares). The purchase price of the properly tendered shares was equal to $13.6639 per share for an aggregate purchase price of $54,468,760. If the conditions of the second conditional tender offer are met, the second conditional cash tender offer would begin on or about June 25, 2020.

In addition, Municipal Fund, California Fund and New York Fund issued 21,854,763 shares, 3,987,531 shares and 2,456,514 shares, respectively, in connection with the reorganizations described below in Note 7 during the year ended September 30, 2019.

At March 31, 2020, one shareholder owned 11.4% of the outstanding shares of Municipal Fund.

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, 2020, the hierarchy of inputs used in valuing the Funds’ investments, which are carried at value, were as follows:


Municipal Fund
Asset Description	Level 1		Level 2		Level 3		Total

Tax-Exempt Investments	$	—	$	1,774,945,902	$	—	$	1,774,945,902

7 Reorganizations

Municipal Fund

During the year ended September 30, 2019, Municipal Fund acquired the net assets of Eaton Vance Massachusetts Municipal Bond Fund (Massachusetts Fund), Eaton Vance Michigan Municipal Bond Fund (Michigan Fund), Eaton Vance New Jersey Municipal Bond Fund (New Jersey Fund), Eaton Vance Ohio Municipal Bond Fund (Ohio Fund), Eaton Vance Pennsylvania Municipal Bond Fund (Pennsylvania Fund) and Eaton Vance Municipal Bond Fund II (Municipal Fund II), (collectively, the “Acquired Funds”), pursuant to Agreements and Plans of Reorganization (each, a “Plan”) approved by the respective shareholders of the Acquired Funds. Under the terms of each Plan, the common shares of each Acquired Fund were, in effect, exchanged for new common shares of Municipal Fund with an equal aggregate net asset value. The purpose of each reorganization was to combine two funds managed by EVM with similar investment objectives and policies. Each reorganization was structured as atax-free reorganization under the Internal Revenue Code.

The net assets and shares outstanding of each Acquired Fund as of the close of business on the closing date of each reorganization and the number of shares issued in each reorganization by Municipal Fund were as follows:


Closing Date	Acquired Fund		Acquired Fund Shares Outstanding		Acquired Fund Net Assets		Municipal Fund Shares Issued

December 14, 2018		Massachusetts Fund		1,768,514	$	25,238,430		1,951,416

December 14, 2018		Michigan Fund		1,500,065	$	21,836,875		1,688,410

January 18, 2019		New Jersey Fund		2,579,166	$	35,868,539		2,745,404

January 18, 2019		Ohio Fund		2,537,940	$	33,611,079		2,572,612

January 18, 2019		Pennsylvania Fund		2,960,040	$	40,019,819		3,063,142

March 22, 2019		Municipal Fund II		10,013,381	$	131,418,955		9,833,779

The investment portfolios of the Acquired Funds were the principal assets acquired by Municipal Fund. For financial reporting purposes, assets received and shares issued by Municipal Fund were recorded at fair value; however, the identified cost of the investments received from the Acquired Funds were carried forward to align ongoing reporting of Municipal Fund’s realized and unrealized gains and losses with amounts distributable to shareholders for tax purposes.

Investments and net assets immediately before each reorganization and combined net assets were as follows:

Massachusetts Fund	$	(193,263	)	$	1,477,136

Michigan Fund	$	38,536		$	909,608

Pennsylvania Fund	$	(1,646,291	)	$	1,859,260

Municipal Fund II	$	(8,689,724	)	$	12,226,970

Assuming each reorganization had been completed on October 1, 2018, the beginning of Municipal Fund’s annual reporting period, Municipal Fund’s pro forma results of operations for the year ended September 30, 2019 are as follows:



Net investment income	$	44,715,266

Net realized and unrealized gain	$	85,302,373

Net increase in net assets from operations	$	130,017,639

Because the combined investment portfolios have been managed as a single integrated portfolio since the closings of the reorganizations, it was not practicable to separate the amounts of revenue and earnings of each Acquired Fund since the time of each closing through September 30, 2019.

California Fund

At the close of business on December 14, 2018, California Fund acquired the net assets of Eaton Vance California Municipal Bond Fund II (California Fund II) pursuant to an Agreement and Plan of Reorganization (the “Plan”) approved by shareholders of California Fund II. Under the terms of the Plan, the common shares of California Fund II were, in effect, exchanged for new common shares of California Fund with an equal aggregate net asset value. The purpose of the reorganization was to combine two funds managed by EVM with substantially similar investment objectives and policies. The reorganization was structured as atax-free reorganization under the Internal Revenue Code.

The net assets and shares outstanding of California Fund II as of the close of business on December 14, 2018 and the number of shares issued in the reorganization by California Fund were as follows:


California Fund II			California Fund
Shares Outstanding	Net Assets		Shares Issued

3,886,356	$	46,853,792		3,987,531

The investment portfolio of California Fund II, with a fair value of $79,072,648 and identified cost of $76,841,447 was the principal asset acquired by California Fund. For financial reporting purposes, assets received and shares issued by California Fund were recorded at fair value; however, the identified cost of the investments received from California Fund II was carried forward to align ongoing reporting of California Fund’s realized and unrealized gains and losses with amounts distributable to shareholders for tax purposes. The aggregate net assets of California Fund immediately before the reorganization were $251,386,702. The net assets of California Fund II at that date of $46,853,792, including $5,045,990 of accumulated net realized losses and $2,231,201 of unrealized appreciation, were combined with those of California Fund, resulting in combined net assets of $298,240,494.

Assuming the reorganization had been completed on October 1, 2018, the beginning of California Fund’s annual reporting period, California Fund’s pro forma results of operations for the year ended September 30, 2019 are as follows:



Net investment income	$	11,021,853

Net realized and unrealized gain	$	20,231,175

Net increase in net assets from operations	$	31,253,028

Because the combined investment portfolios have been managed as a single integrated portfolio since the reorganization was completed, it was not practicable to separate the amounts of revenue and earnings of California Fund II since December 14, 2018 through September 30, 2019.

New York Fund

At the close of business on December 14, 2018, New York Fund acquired the net assets of Eaton Vance New York Municipal Bond Fund II (New York Fund II) pursuant to an Agreement and Plan of Reorganization (the “Plan”) approved by shareholders of New York Fund II. Under the terms of the Plan, the common shares of New York Fund II were, in effect, exchanged for new common shares of New York Fund with an equal aggregate net asset value. The purpose of the reorganization was to combine two funds managed by EVM with substantially similar investment objectives and policies.

New York Fund II			New York Fund
Shares Outstanding	Net Assets		Shares Issued

2,556,510	$	31,246,579		2,456,514

The investment portfolio of New York Fund II, with a fair value of $53,007,450 and identified cost of $51,991,914 was the principal asset acquired by New York Fund. For financial reporting purposes, assets received and shares issued by New York Fund were recorded at fair value; however, the identified cost of the investments received from New York Fund II was carried forward to align ongoing reporting of New York Fund’s realized and unrealized gains and losses with amounts distributable to shareholders for tax purposes. The aggregate net assets of New York Fund immediately before the reorganization were $199,216,655. The net assets of New York Fund II at that date of $31,246,579, including $1,942,265 of accumulated net realized losses and $1,015,536 of unrealized appreciation, were combined with those of New York Fund, resulting in combined net assets of $230,463,234.

Assuming the reorganization had been completed on October 1, 2018, the beginning of New York Fund’s annual reporting period, New York Fund’s pro forma results of operations for the year ended September 30, 2019 are as follows:



Net investment income	$	8,566,062

Net realized and unrealized gain	$	13,775,428

Net increase in net assets from operations	$	22,341,490

Because the combined investment portfolios have been managed as a single integrated portfolio since the reorganization was completed, it was not practicable to separate the amounts of revenue and earnings of New York Fund II since December 14, 2018 through September 30, 2019.

8 Risks and Uncertainties

An outbreak of respiratory disease caused by a novel coronavirus that was first detected in China in December 2019 has spread rapidly internationally. This coronavirus has resulted in closing borders, enhanced health screenings, changes to healthcare service preparation and delivery, quarantines, cancellations, disruptions to supply chains and customer activity, as well as general concern and uncertainty. The impact of this outbreak has negatively affected the worldwide economy, as well as the economies of individual countries and individual companies and can affect the market in general in significant and unforeseen ways. Health crises caused by outbreaks, such as the coronavirus outbreak, may exacerbate otherpre-existing political, social and economic risks and disrupt normal market conditions and operations. The near-term impact of this coronavirus has resulted in substantial market volatility, which may have an adverse effect on the Funds’ investments.

Potential for Conflicts of Interest. It is possible that conflicts of interest may arise in connection with a portfolio manager’s management of the Fund’s investments on the one hand and the investments of other accounts for which a portfolio manager is responsible on the other. For example, a portfolio manager may have conflicts of interest in allocating management time, resources and investment opportunities among the Fund and other accounts he or she advises. In addition, due to differences in the investment strategies or restrictions between the Fund and the other accounts, the portfolio manager may take action with respect to another account that differs from the action taken with respect to the Fund. In some cases, another account managed by a portfolio manager may compensate the investment adviser based on the performance of the securities held by that account. The existence of such a performance based fee may create additional conflicts of interest for the portfolio manager in the allocation of management time, resources and investment opportunities. Whenever conflicts of interest arise, the portfolio manager will endeavor to exercise his or her discretion in a manner that he or she believes is equitable to all interested persons. EVM has adopted several policies and procedures designed to address these potential conflicts including a code of ethics and policies that govern the investment adviser’s trading practices, including among other things the aggregation and allocation of trades among clients, brokerage allocations, cross trades and best execution.

Compensation Structure for EVM

Compensation of EVM’s portfolio managers and other investment professionals has the following primary components: (1) a base salary, (2) an annual cash bonus, (3) annualnon-cash compensation consisting of options to purchase shares of Eaton Vance Corp. (“EVC”) nonvoting common stock and/or restricted shares of EVC nonvoting common stock that generally are subject to a vesting schedule and (4) (for equity portfolio managers) a Deferred Alpha Incentive Plan, which pays a deferred cash award tied to future excess returns in certain equity strategy portfolios. EVM’s investment professionals also receive certain retirement, insurance and other benefits that are broadly available to EVM’s employees. Compensation of EVM’s investment professionals is reviewed primarily on an annual basis. Cash bonuses, stock-based compensation awards, and adjustments in base salary are typically paid or put into effect at or shortly after the October 31st fiscal year end of EVC.

Method to Determine Compensation. EVM compensates its portfolio managers based primarily on the scale and complexity of their portfolio responsibilities and the total return performance of managed funds and accounts versus the benchmark(s) stated in the prospectus, as well as an appropriate peer group (as described below). In addition to rankings within peer groups of funds on the basis of absolute performance, consideration may also be given to relative risk-adjusted performance. Risk-adjusted performance measures include, but are not limited to Sharpe ratio, which uses standard deviation and excess return to determine reward per unit of risk. Performance is normally based on periods ending on the September 30th preceding fiscal year end. Fund performance is normally evaluated primarily versus peer groups of funds as determined by Lipper Inc. and/or Morningstar, Inc. When a fund’s peer group as determined by Lipper or Morningstar is deemed by EVM’s management not to provide a fair comparison, performance may instead be evaluated primarily against a custom peer group or market index. In evaluating the performance of a fund and its manager, primary emphasis is normally placed on three-year performance, with secondary consideration of performance over longer and shorter periods. For funds that aretax-managed or otherwise have an objective ofafter-tax returns, performance is measured net of taxes. For other funds, performance is evaluated on apre-tax basis. For funds with an investment objective other than total return (such as current income), consideration will also be given to the fund’s success in achieving its objective. For managers responsible for multiple funds and accounts, investment performance is evaluated on an aggregate basis, based on averages or weighted averages among managed funds and accounts. Funds and accounts that have performance-based advisory fees are not accorded disproportionate weightings in measuring aggregate portfolio manager performance. Pursuant to the Deferred Alpha Incentive Plan, a portion of the compensation payable to equity portfolio managers and investment professionals will be determined based on the ability of one or more accounts managed by such manager, that are not advised by Calvert Management and Research to achieve a specified target average annual gross return over a three year period in excess of the account benchmark. The cash award to be payable at the end of the three year term will be established at the inception of the term and will be adjusted positively or negatively to the extent that the average annual gross return varies from the specified target return.

The compensation of portfolio managers with other job responsibilities (such as heading an investment group or providing analytical support to other portfolios) will include consideration of the scope of such responsibilities and the managers’ performance in meeting them.

EVM seeks to compensate portfolio managers commensurate with their responsibilities and performance, and competitive with other firms within the investment management industry. EVM participates in investment-industry compensation surveys and utilizes survey data as a factor in determining salary, bonus and stock-based compensation levels for portfolio managers and other investment professionals. Salaries, bonuses and stock-based compensation are also influenced by the operating performance of EVM and its parent company. The overall annual cash bonus pool is generally based on a substantially fixed percentage ofpre-bonus adjusted

operating income. While the salaries of EVM’s portfolio managers are comparatively fixed, cash bonuses and stock-based compensation may fluctuate significantly from year to year, based on changes in manager performance and other factors as described herein. For a high performing portfolio manager, cash bonuses and stock-based compensation may represent a substantial portion of total compensation.
