1 Significant Accounting Policies

Calvert Small-Cap Fund (the Fund) is a diversified series of Calvert Impact Fund, Inc. (the Corporation). The Corporation is a Maryland corporation registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company. The investment objective of the Fund is to seek to provide long-term capital appreciation through investment primarily in small-cap common stocks of U.S. companies.

The Fund offers four classes of shares. Class A shares are generally sold subject to a sales charge imposed at time of purchase. A contingent deferred sales charge of 1.00% may apply to certain redemptions of Class A shares for accounts for which no sales charge was paid, if redeemed within 12 months of purchase. Class C shares are sold without a front-end sales charge, and with certain exceptions, are charged a contingent deferred sales charge of 1.00% on shares redeemed within 12 months of purchase. Class C shares are only available for purchase through a financial intermediary. Effective November 5, 2020, Class C shares automatically convert to Class A shares eight years after their purchase as described in the Fund's prospectus. Class I and Class R6 shares are sold at net asset value, are not subject to a sales charge and are sold only to certain eligible investors. Each class represents a pro rata interest in the Fund, but votes separately on class-specific matters and is subject to different expenses.

The Fund applies the accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946, *Financial Services – Investment Companies* (ASC 946). Subsequent events, if any, through the date that the financial statements were issued have been evaluated in the preparation of the financial statements.

A Investment Valuation— Net asset value per share is determined every business day as of the close of the regular session of the New York Stock Exchange (generally 4:00 p.m. Eastern time). The Fund uses independent pricing services approved by the Board of Directors (the Board) to value its investments wherever possible. Investments for which market quotations are not available or deemed not reliable are fair valued in good faith by the

Board's valuation designee.

U.S. generally accepted accounting principles (U.S. GAAP) establishes a disclosure hierarchy that categorizes the inputs to valuation techniques used to value assets and liabilities at measurement date. These inputs are summarized in the three broad levels listed below:

Level 1 - quoted prices in active markets for identical securities

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

Level 3 - significant unobservable inputs (including the Fund's own assumptions in determining the fair value of investments)

The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

Valuation techniques used to value the Fund's investments by major category are as follows:

**Equity Securities. Equity securities (including warrants and rights) listed on a U.S. securities exchange generally are valued at the last sale or closing price as reported by an independent pricing service on the primary market or exchange on which they are traded and are categorized as Level 1 in the hierarchy. Equity securities listed on the NASDAQ National Market System are valued at the NASDAQ official closing price and are categorized as Level 1 in the hierarchy. Unlisted or listed securities for which closing sales prices or closing quotations are not available are valued at the mean between the latest available bid and ask prices and are categorized as Level 2 in the hierarchy.**

**Other Securities. Investments in management investment companies (including money market funds) that do not trade on an exchange are valued at the net asset value as of the close of each business day and are categorized as Level 1 in the hierarchy.**

**Fair Valuation. In connection with Rule 2a-5 of the 1940 Act, the Board has designated the 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 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 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.**

The values assigned to fair value investments are based on available information and do not necessarily represent amounts that might ultimately be realized. Further, due to the inherent uncertainty of valuations of such investments, the fair values may differ significantly from the values that would have been used had an active market existed, and the differences could be material.

<sup>(1)</sup> The level classification by major category of investments is the same as the category presentation in the Schedule of Investments.

B Investment Transactions and Income— Investment transactions for financial statement purposes are accounted for on trade date. Realized gains and losses are recorded on an identified cost basis and may include proceeds from litigation. Dividend income is recorded on the ex-dividend date for dividends received in cash and/or securities. Non-cash dividends are recorded at the fair value of the securities received. Distributions received that represent a return of capital are recorded as a reduction of cost of investments. Distributions received that represent a capital gain are recorded as a realized gain. Interest income is accrued as earned.

C Share Class Accounting— Realized and unrealized gains and losses and net investment income and losses, other than class-specific expenses, are allocated daily to each class of shares based upon the relative net assets of each class to the total net assets of the Fund. Expenses arising in connection with a specific class are charged directly to that class. Sub-accounting, recordkeeping and similar administrative fees payable to financial intermediaries, which are a component of transfer agency fees and expenses on the Statement of Operations, are not allocated to Class R6 shares.

D Distributions to Shareholders— Distributions to shareholders are recorded by the Fund on ex-dividend date. Distributions from net investment income and distributions from net realized capital gains, if any, are paid at least annually. Distributions are declared separately for each class of shares. Distributions are determined in accordance with income tax regulations, which may differ from U.S. GAAP; accordingly, periodic reclassifications are made within the Fund's capital accounts to reflect income and gains available for distribution under income tax regulations.

E Estimates— The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates.

F Indemnifications— The Corporation's By-Laws provide for indemnification for Directors or officers of the Corporation and certain other parties, to the fullest extent permitted by Maryland law and the 1940 Act, provided certain conditions are met. Additionally, in the normal course of business, the Fund enters into agreements with service providers that may contain indemnification clauses. The Fund's maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Fund that have not yet occurred.

G Federal and Other Taxes— No provision for federal income or excise tax is required since the Fund intends to continue to qualify as a regulated investment company under the Internal Revenue Code and to distribute substantially all of its taxable earnings. Management has analyzed the Fund's tax positions taken for all open federal income tax years and has concluded that no provision for federal income tax is required in the Fund's financial statements. A Fund's federal tax return is subject to examination by the Internal Revenue Service for a period of three years from the date of filing.

H Segment Reporting— The Fund operates as a single reportable segment, an investment company whose investment objective(s) is included in Note 1. The Fund's President acts as the Fund's Chief Operating Decision Maker (CODM), who is responsible for assessing the performance of the Fund's single segment and deciding how to allocate the segment's resources. To perform this function, the CODM reviews the information in the Fund's financial statements.

I Interim Financial Statements— The interim financial statements relating to March 31, 2026 and for the six months then ended have not been audited by an independent registered public accounting firm, but in the opinion of the Fund's management, reflect all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of the financial statements.

2 Related Party Transactions

The investment advisory fee is earned by Calvert Research and Management (CRM), an indirect, wholly-owned subsidiary of Morgan Stanley, as compensation for investment advisory services rendered to the Fund. The investment advisory fee is computed at the annual rate of 0.68% of the Fund's average daily net assets and is payable monthly. For the six months ended March 31, 2026, the investment advisory fee amounted to $6,620,935.

The investment advisory fee paid by the Fund is reduced by an amount equal to its pro rata share of the advisory and administration fees paid by the Fund due to its investment in the Liquidity Fund. For the six months ended March 31, 2026, the investment advisory fee paid was reduced by $9,044 relating to the Fund's investment in the Liquidity Fund.

CRM has agreed to reimburse the Fund's operating expenses to the extent that total annual operating expenses (relating to ordinary operating expenses only and excluding expenses such as brokerage commissions, acquired fund fees and expenses of unaffiliated funds, borrowing costs, taxes or litigation expenses) exceed 1.21%, 1.96%, 0.96% and 0.90% for Class A, Class C, Class I and Class R6, respectively, of such class's average daily net assets. The expense reimbursement agreement with CRM may be changed or terminated after February 1, 2027. For the six months ended March 31, 2026, CRM waived and/or reimbursed expenses of $340,595.

The administrative fee is earned by CRM as compensation for administrative services rendered to the Fund. The fee is computed at an annual rate of 0.12% of the Fund's average daily net assets attributable to Class A, Class C, Class I and Class R6 and is payable monthly. For the six months ended March 31, 2026, CRM was paid administrative fees of $1,168,400.

The Fund has in effect a distribution plan for Class A shares (Class A Plan) pursuant to Rule 12b-1 under the 1940 Act. Pursuant to the Class A Plan, the Fund pays Eaton Vance Distributors, Inc. (EVD), an affiliate of CRM and the Fund's principal underwriter, a distribution and service fee of 0.25% per annum of its average daily net assets attributable to Class A shares for distribution services and facilities provided to the Fund by EVD, as well as for personal services and/or the maintenance of shareholder accounts. The Fund also has in effect a distribution plan for Class C shares (Class C Plan) pursuant to Rule 12b-1 under the 1940 Act. Pursuant to the Class C Plan, the Fund pays EVD amounts equal to 0.75% per annum of its average daily net assets attributable to Class C shares for providing ongoing distribution services and facilities to the Fund. In addition, pursuant to the Class C Plan, the Fund also makes payments of service fees to EVD, financial intermediaries and other persons in amounts equal to 0.25% per annum of its average daily net assets attributable to that class. Service fees paid or accrued are for personal services and/or the maintenance of shareholder accounts. Distribution and service fees paid or accrued for the six months ended March 31, 2026 amounted to $309,670 and $100,419 for Class A shares and Class C shares, respectively.

The Fund was informed that EVD received $4,019 as its portion of the sales charge on sales of Class A shares for the six months ended March 31, 2026. The Fund was also informed that EVD received less than $100 and $942 of contingent deferred sales charges paid by Class A and Class C shareholders, respectively, for the same period.

Eaton Vance Management (EVM), an affiliate of CRM, provides sub-transfer agency and related services to the Fund pursuant to a Sub-Transfer Agency Support Services Agreement. For the six months ended March 31, 2026, sub-transfer agency fees and expenses incurred to EVM amounted to $49,664 and are included in transfer agency fees and expenses on the Statement of Operations.

Each Director of the Fund who is not an employee of CRM or its affiliates receives an annual fee of $250,000, an annual Committee fee ranging from $8,500 to $16,500 depending on the Committee, and may receive a fee of $10,000 for special meetings. The Board chair receives an additional $75,000 ($55,000 prior to January 1, 2026) annual fee, Committee chairs receive an additional $20,000 annual fee and the special equities liaison receives an additional $2,500 annual fee. Eligible Directors may participate in a Deferred Compensation Plan (the Plan). Amounts deferred under the Plan are treated as though equal dollar amounts had been invested in shares of the Fund or other Calvert funds selected by the Directors. The Fund purchases shares of the funds selected equal to the dollar amounts deferred under the Plan, resulting in an asset equal to the deferred compensation liability. Obligations of the Plan are paid solely from the Fund's assets. Directors' fees are allocated to each of the Calvert funds served. Salaries and fees of officers and Directors of the Fund who are employees of CRM or its affiliates are paid by CRM.

3 Investment Activity

During the six months ended March 31, 2026, the cost of purchases and proceeds from sales of investments, other than short-term securities and in-kind transactions, were $397,014,401 and $890,649,613, respectively. In-kind sales for the six months ended March 31, 2026 aggregated $230,064,396.

4 Distributions to Shareholders and Income Tax Information

The cost and unrealized appreciation (depreciation) of investments of the Fund at March 31, 2026, as determined on a federal income tax basis, were as follows:

---

| | |
|:---|:---|
| **Aggregate cost** | &nbsp;&nbsp;&nbsp;&nbsp;**$1411583154** |
| Gross unrealized appreciation | &nbsp;&nbsp;&nbsp;&nbsp;$234167107 |
| Gross unrealized depreciation | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(126379889) |
| **Net unrealized appreciation** | &nbsp;&nbsp;&nbsp;&nbsp;**$107787218** |

5 Securities Lending

To generate additional income, the Fund may lend its securities pursuant to a securities lending agency agreement with State Street Bank and Trust Company (SSBT), the securities lending agent. Security loans are subject to termination by the Fund at any time and, therefore, are not considered illiquid investments. The Fund requires that the loan be continuously collateralized by either cash or securities in an amount at least equal to the market value of the securities on loan. The market value of securities loaned is determined daily and any additional required collateral is delivered to the Fund on the next business day. Cash collateral is generally invested in a money market fund registered under the 1940 Act that is managed by an affiliate of SSBT. Any gain or loss in the market price of the loaned securities that might occur and any interest earned or dividends declared during the term of the loan would accrue to the account of the Fund. Income earned on the investment of collateral, net of broker rebates and other expenses incurred by the securities lending agent, is split between the Fund and the securities lending agent based on agreed upon contractual terms. Non-cash collateral, if any, is held by the lending agent on behalf of the Fund and cannot be sold or re-pledged by the Fund; accordingly, such collateral is not reflected in the Statement of Assets and Liabilities.

The risks associated with lending portfolio securities include, but are not limited to, possible delays in receiving additional collateral or in the recovery of the loaned securities, possible loss of rights to the collateral should the borrower fail financially, as well as risk of loss in the value of the collateral or the value of the investments made with the collateral. The securities lending agent shall indemnify the Fund in the case of default of any securities borrower.

At March 31, 2026, the total value of securities on loan was $422,165 and the total value of collateral received was $428,389, comprised of cash of $103,328 and U.S. government and/or agencies securities of $325,061.

The following table provides a breakdown of securities lending transactions accounted for as secured borrowings, the obligations by class of collateral pledged, and the remaining contractual maturity of those transactions as of March 31, 2026.

| Common Stocks | &nbsp;&nbsp;$103328 | &nbsp;&nbsp;$— | &nbsp;&nbsp;$— | &nbsp;&nbsp;$— | &nbsp;&nbsp;$103328 |

The carrying amount of the liability for deposits for securities loaned at March 31, 2026 approximated its fair value. If measured at fair value, such liability would have been considered as Level 2 in the fair value hierarchy (see Note 1A) at March 31, 2026.

6 Line of Credit

The Fund participates with other portfolios and funds managed by EVM and its affiliates, including CRM, in a $650 million unsecured revolving line of credit agreement with a group of banks, which is in effect through October 20, 2026. Borrowings are made by the Fund solely for temporary purposes related to redemptions and other short-term cash needs. Interest is charged to the Fund based on its borrowings generally at an amount above either the Secured Overnight Financing Rate (SOFR) or Federal Funds rate. In addition, a fee computed at an annual rate of 0.15% on the daily unused portion of the line of credit is allocated among the participating portfolios and funds at the end of each quarter. In connection with the renewal of the agreement in October 2025, an arrangement fee of $150,000 was incurred that was allocated to the participating portfolios and funds. Because the line of credit is not available exclusively to the Fund, it may be unable to borrow some or all of its requested amounts at any particular time.

The Fund had no borrowings outstanding pursuant to its line of credit at March 31, 2026. Average borrowings and the weighted average annual interest rate (excluding fees) for the six months ended March 31, 2026 were $5,164,670 and 4.70%, respectively.

1 Significant Accounting Policies

Calvert Global Energy Solutions Fund (Global Energy Solutions) and Calvert Global Water Fund (Global Water) (each a Fund and collectively, the Funds) are diversified series of Calvert Impact Fund, Inc. (the Corporation). The Corporation is a Maryland corporation registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company. The investment objective of Global Energy Solutions is to seek to track the performance of the Calvert Global Energy Research Index. Global Energy Solutions invests in equity securities of U.S. and non-U.S. companies whose main business is sustainable energy solutions, or that are significantly involved in the sustainable energy solutions industry. The investment objective of Global Water is to seek to track the performance of the Calvert Global Water Research Index. Global Water invests in equity securities of U.S. and non-U.S. companies whose main business is in the water industry, or that are significantly involved in water-related services or technologies.

Each Fund offers three classes of shares. Class A shares are generally sold subject to a sales charge imposed at time of purchase. A contingent deferred sales charge of 1.00% may apply to certain redemptions of Class A shares for accounts for which no sales charge was paid, if redeemed within 12 months of purchase. Class C shares are sold without a front-end sales charge, and with certain exceptions, are charged a contingent deferred sales charge of 1.00% on shares redeemed within 12 months of purchase. Class C shares are only available for purchase through a financial intermediary. Effective November 5, 2020, Class C shares automatically convert to Class A shares eight years after their purchase as described in the Funds' prospectus. Class I shares are sold at net asset value, are not subject to a sales charge and are sold only to certain eligible investors. Each class represents a pro rata interest in each Fund, but votes separately on class-specific matters and is subject to different expenses.

Each Fund applies the accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946, *Financial Services – Investment Companies* (ASC 946). Subsequent events, if any, through the date that the financial statements were issued have been evaluated in the preparation of the financial statements.

A Investment Valuation— Net asset value per share is determined every business day as of the close of the regular session of the New York Stock Exchange (generally 4:00 p.m. Eastern time). The Funds use independent pricing services approved by the Board of Directors (the Board) to value their investments wherever possible. Investments for which market quotations are not available or deemed not reliable are fair valued in good faith by the Board's valuation designee.

U.S. generally accepted accounting principles (U.S. GAAP) establishes a disclosure hierarchy that categorizes the inputs to valuation techniques used to value assets and liabilities at measurement date. These inputs are summarized in the three broad levels listed below:

Level 1 – quoted prices in active markets for identical securities

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

Level 3 – significant unobservable inputs (including each Fund's own assumptions in determining the fair value of investments)

The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

Valuation techniques used to value each Fund's investments by major category are as follows:

**Equity Securities. Equity securities (including warrants and rights) listed on a U.S. securities exchange generally are valued at the last sale or closing price as reported by an independent pricing service on the primary market or exchange on which they are traded and are categorized as Level 1 in the hierarchy. Equity securities listed on the NASDAQ National Market System are valued at the NASDAQ official closing price and are categorized as Level 1 in the hierarchy. Unlisted or listed securities for which closing sales prices or closing quotations are not available are valued at the mean between the latest available bid and ask prices and are categorized as Level 2 in the hierarchy. The daily valuation of exchange-traded foreign securities generally is determined as of the close of trading on the principal exchange on which such securities trade. Events occurring after the close of trading on foreign exchanges may result in adjustments to the valuation of foreign securities to more accurately reflect their fair value as of the close of regular trading on the New York Stock Exchange. When valuing foreign equity securities that meet certain criteria, the Funds' Board has approved the use of a fair value service that values such securities to reflect market trading that occurs after the close of the applicable foreign markets of comparable securities or other instruments that have a strong correlation to the fair-valued securities. Such securities are categorized as Level 2 in the hierarchy.**

**Other Securities. Investments in management investment companies (including money market funds) that do not trade on an exchange are valued at the net asset value as of the close of each business day and are categorized as Level 1 in the hierarchy.**

**Fair Valuation. In connection with Rule 2a-5 of the 1940 Act, the Board has designated each 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 the Funds 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.**

The values assigned to fair value investments are based on available information and do not necessarily represent amounts that might ultimately be realized. Further, due to the inherent uncertainty of valuations of such investments, the fair values may differ significantly from the values that would have been used had an active market existed, and the differences could be material.

The following tables summarize the market value of each of the Funds' holdings as of March 31, 2026, based on the inputs used to value them:

B Investment Transactions and Income— Investment transactions for financial statement purposes are accounted for on trade date. Realized gains and losses are recorded on an identified cost basis and may include proceeds from litigation. Dividend income is recorded on the ex-dividend date for dividends received in cash and/or securities or, in the case of dividends on certain foreign securities, as soon as the Fund is informed of the ex-dividend date. Non-cash dividends are recorded at the fair value of the securities received. Withholding taxes on foreign dividends, if any, have been provided for in accordance with the Funds' understanding of the applicable country's tax rules and rates. As a result of several court cases in certain countries across the European Union (EU), Global Water filed additional tax reclaims for previously withheld taxes on dividends earned in those countries. Income recognized, if any, for EU reclaims and interest thereon is reflected as other income in the Statement of Operations, and any related receivable, if any, is reflected as European Union tax reclaims receivable in the Statement of Assets and Liabilities. Any fees associated with these filings are reflected in miscellaneous expenses in the Statement of Operations. When uncertainty exists as to the ultimate resolution of these proceedings, the likelihood of receipt of these EU reclaims, and the potential timing of payment, no amounts are reflected in the financial statements. For U.S. income tax purposes, EU reclaims received by the Fund, if any, may reduce the amount of foreign taxes Fund shareholders can use as tax deductions or credits on their income tax returns. In the event that EU

reclaims received by the Fund during a fiscal year exceed foreign withholding taxes paid by the Fund, and the Fund previously passed through to its shareholders foreign taxes incurred by the Fund to be used as a credit or deduction on a shareholder's income tax return, the Fund may be required to enter into a closing agreement with the Internal Revenue Service in order to pay the associated tax liability on behalf of the Fund's shareholders. Distributions received that represent a return of capital are recorded as a reduction of cost of investments. Distributions received that represent a capital gain are recorded as a realized gain. Interest income is accrued as earned.

C Share Class Accounting— Realized and unrealized gains and losses and net investment income and losses, other than class-specific expenses, are allocated daily to each class of shares based upon the relative net assets of each class to the total net assets of each Fund. Expenses arising in connection with a specific class are charged directly to that class.

D Foreign Currency Transactions— The Funds' accounting records are maintained in U.S. dollars. For valuation of assets and liabilities on each date of net asset value determination, foreign denominations are converted into U.S. dollars using the current exchange rate. Security transactions, income and expenses are translated at the prevailing rate of exchange on the date of the event. Recognized gains or losses on investment transactions attributable to changes in foreign currency exchange rates are recorded for financial statement purposes as net realized gains and losses on investments. That portion of unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed.

E Distributions to Shareholders— Distributions to shareholders are recorded by the Funds on ex-dividend date. Distributions from net investment income and distributions from net realized capital gains, if any, are paid at least annually. Distributions are declared separately for each class of shares. Distributions are determined in accordance with income tax regulations, which may differ from U.S. GAAP; accordingly, periodic reclassifications are made within the Funds' capital accounts to reflect income and gains available for distribution under income tax regulations.

F Estimates— The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates.

G Indemnifications— The Corporation's By-Laws provide for indemnification for Directors or officers of the Corporation and certain other parties, to the fullest extent permitted by Maryland law and the 1940 Act, provided certain conditions are met. 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 Federal and Other Taxes— No provision for federal income or excise tax is required since each Fund intends to continue to qualify as a regulated investment company under the Internal Revenue Code and to distribute substantially all of its taxable earnings.

In addition to the requirements of the Internal Revenue Code, each Fund may also be subject to local taxes on the recognition of capital gains in certain countries. In determining the daily net asset value, each Fund estimates the accrual for such taxes, if any, based on the unrealized appreciation on certain portfolio securities and the related tax rates. Taxes attributable to unrealized appreciation are included in the respective Fund's change in unrealized appreciation (depreciation) on investments. Capital gains taxes on securities sold are included in the respective Fund's net realized gain (loss) on investments.

Management has analyzed the Funds' tax positions taken for all open federal income tax years and has concluded that no provision for federal income tax is required in the Funds' financial statements. Each Fund's federal tax return is subject to examination by the Internal Revenue Service for a period of three years from the date of filing.

I Segment Reporting— Each Fund operates as a single reportable segment, an investment company whose investment objective(s) is included in Note 1. 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, 2026 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.

Each Fund has in effect a distribution plan for Class A shares (Class A Plan) pursuant to Rule 12b-1 under the 1940 Act. Pursuant to the Class A Plan, each Fund pays Eaton Vance Distributors, Inc. (EVD), an affiliate of CRM and the Funds' principal underwriter, a distribution and service fee of 0.25% per annum of its average daily net assets attributable to Class A shares for distribution services and facilities provided to the Funds by EVD, as well as for personal services and/or the maintenance of shareholder accounts.

Eaton Vance Management (EVM), an affiliate of CRM, provides sub-transfer agency and related services to the Funds pursuant to a Sub-Transfer Agency Support Services Agreement. For the six months ended March 31, 2026, sub-transfer agency fees and expenses for Global Energy Solutions and Global Water incurred to EVM amounted to $22,506 and $38,653, respectively, and are included in transfer agency fees and expenses on the Statements of Operations.

Each Director of the Funds who is not an employee of CRM or its affiliates receives an annual fee of $250,000, an annual Committee fee ranging from $8,500 to $16,500 depending on the Committee, and may receive a fee of $10,000 for special meetings. The Board chair receives an additional $75,000 ($55,000 prior to January 1, 2026) annual fee, Committee chairs receive an additional $20,000 annual fee and the special equities liaison receives an additional $2,500 annual fee. Eligible Directors may participate in a Deferred Compensation Plan (the Plan). Amounts deferred under the Plan are treated as though equal dollar amounts had been invested in shares of the Funds or other Calvert funds selected by the Directors. The Funds purchase shares of the funds selected equal to the dollar amounts deferred under the Plan, resulting in an asset equal to the deferred compensation liability. Obligations of the Plan are paid solely from the Funds' assets. Directors' fees are allocated to each of the Calvert funds served. Salaries and fees of officers and Directors of the Funds who are employees of CRM or its affiliates are paid by CRM.

4 Distributions to Shareholders and Income Tax Information

At September 30, 2025, Global Energy Solutions, for federal income tax purposes, had deferred capital losses of $4,615,881 which would reduce the 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 Fund of any liability for federal income or excise tax. The deferred capital losses are treated as arising on the first day of the Fund's next taxable year, can be carried forward for an unlimited period, and retain the same short-term or long-term character as when originally deferred. Of the deferred capital losses at September 30, 2025, $4,615,881 are long-term.

The cost and unrealized appreciation (depreciation) of investments of the Funds at March 31, 2026, as determined on a federal income tax basis, were as follows:

5 Securities Lending

To generate additional income, the Funds may lend their securities pursuant to a securities lending agency agreement with State Street Bank and Trust Company (SSBT), the securities lending agent. Security loans are subject to termination by the Funds at any time and, therefore, are not considered illiquid investments. The Funds require that the loan be continuously collateralized by either cash or securities in an amount at least equal to the market value of the securities on loan. The market value of securities loaned is determined daily and any additional required collateral is delivered to the Funds on the next business day. Cash collateral is generally invested in a money market fund registered under the 1940 Act that is managed by an affiliate of SSBT. Any gain or loss in the market price of the loaned securities that might occur and any interest earned or dividends declared during the term of the loan would accrue to the account of the Funds. Income earned on the investment of collateral, net of broker rebates and other expenses incurred by the securities lending agent, is split between the Funds and the securities lending agent based on agreed upon contractual terms. Non-cash collateral, if any, is held by the lending agent on behalf of a Fund and cannot be sold or re-pledged by the Fund; accordingly, such collateral is not reflected in the Statements of Assets and Liabilities.

The risks associated with lending portfolio securities include, but are not limited to, possible delays in receiving additional collateral or in the recovery of the loaned securities, possible loss of rights to the collateral should the borrower fail financially, as well as risk of loss in the value of the collateral or the value of the investments made with the collateral. The securities lending agent shall indemnify the Funds in the case of default of any securities borrower.

The carrying amounts of the liabilities for deposits for securities loaned at March 31, 2026 approximated their fair value. If measured at fair value, such liabilities would have been considered as Level 2 in the fair value hierarchy (see Note 1A) at March 31, 2026.

6 Line of Credit

The Funds participate with other portfolios and funds managed by EVM and its affiliates, including CRM, in a $650 million unsecured revolving line of credit agreement with a group of banks, which is in effect through October 20, 2026. Borrowings are made by the Funds solely for temporary purposes related to redemptions and other short-term cash needs. Interest is charged to each Fund based on its borrowings generally at an amount above either the Secured Overnight Financing Rate (SOFR) or Federal Funds rate. In addition, a fee computed at an annual rate of 0.15% on the daily unused portion of the line of credit is allocated among the participating portfolios and funds at the end of each quarter. In connection with the renewal of the agreement in October 2025, an arrangement fee of $150,000 was incurred that was allocated to the participating portfolios and funds. Because the line of credit is not available exclusively to the Funds, a Fund may be unable to borrow some or all of its requested amounts at any particular time.

The Funds had no borrowings outstanding pursuant to their line of credit at March 31, 2026. The Funds did not have any significant borrowings or allocated fees during the six months ended March 31, 2026.

7 Affiliated Investments

At March 31, 2026, the value of each Fund's investment in funds that may be deemed to be affiliated was $405,773 for Global Energy Solutions, which represents 0.2% of its net assets, and $700,555 for Global Water, which represents 0.1% of its net assets. Transactions in such investments by the Funds for the six months ended March 31, 2026 were as follows:

9 Risks and Uncertainties

#### Risks Associated with Foreign Investments
Foreign investments can be adversely affected by political, economic and market developments abroad, including the imposition of economic and other sanctions by the United States or another country, and by acts of terrorism and war. There may be less publicly available information about foreign issuers because they may not be subject to reporting practices, requirements or regulations comparable to those to which United States companies are subject. Foreign markets may be smaller, less liquid and more volatile than the major markets in the United States. Trading in foreign markets typically involves higher expense than trading in the United States. The Funds may have difficulties enforcing their legal or contractual rights in a foreign country. Securities that trade or are denominated in currencies other than the U.S. dollar may be adversely affected by fluctuations in currency exchange rates.

Emerging market securities often involve greater risks than developed market securities. Investment markets within emerging market countries are typically smaller, less liquid, less developed and more volatile than those in more developed markets like the United States, and may be focused in certain economic sectors. The information available about an emerging market issuer may be less reliable than for comparable issuers in more developed capital markets. Governmental actions can have a significant effect on the economic conditions in emerging market countries. It may be more difficult to make a claim or obtain a judgment in the courts of these countries than it is in the United States. The possibility of fraud, negligence, undue influence being exerted by an issuer or refusal to recognize ownership exists in some emerging markets. Disruptions due to work stoppages and trading improprieties in foreign securities markets have caused such markets to close. Emerging market securities are also subject to speculative trading, which contributes to their volatility.

#### Concentration Risk
Global Energy Solutions concentrates its investments in the sustainable energy solutions industry. This industry can be significantly affected by obsolescence of existing technology, short product lifecycles, falling prices and profits, competition from new market entrants and general economic conditions. The industry can also be significantly affected by fluctuations in energy prices and supply and demand of alternative energy fuels, energy conservation, the success of exploration projects and tax and other government regulations and policies. Companies in this industry could be adversely affected by commodity price volatility, imposition of import controls, increased competition, depletion of resources, technological developments and labor relations.

Global Water concentrates its investments in the water industry. This industry can be significantly affected by economic trends or other conditions or developments, such as the availability of water, the level of rainfall and occurrence of other climatic events, changes in water consumption, new technologies relating to the supply of water, and water conservation. The industry can also be significantly affected by environmental considerations, taxation, government regulation (including the increased cost of compliance), inflation, increases in interest rates, price and supply fluctuations, increases in the cost of raw materials and other operating costs, technological advances, and competition from new market entrants.

1 Significant Accounting Policies

Calvert Green Bond Fund (the Fund) is a diversified series of Calvert Impact Fund, Inc. (the Corporation). The Corporation is a Maryland corporation registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company. The investment objective of the Fund is to seek to maximize income, to the extent consistent with preservation of capital, primarily through investment in bonds. The Fund invests primarily in "green" investments which include those issued by companies that develop or provide products or services that seek to provide environmental solutions and/or that support environmental projects, among others.

The Fund offers three classes of shares. Class A shares are generally sold subject to a sales charge imposed at time of purchase. A contingent deferred sales charge of 0.75% may apply to certain redemptions of Class A shares for accounts for which no sales charge was paid, if redeemed within 12 months of purchase. Class I and Class R6 shares are sold at net asset value, are not subject to a sales charge and are sold only to certain eligible investors. Each class represents a pro rata interest in the Fund, but votes separately on class-specific matters and is subject to different expenses.

The Fund applies the accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946, *Financial Services – Investment Companies* (ASC 946). Subsequent events, if any, through the date that the financial statements were issued have been evaluated in the preparation of the financial statements.

A Investment Valuation— Net asset value per share is determined every business day as of the close of the regular session of the New York Stock Exchange (generally 4:00 p.m. Eastern time). The Fund uses independent pricing services approved by the Board of Directors (the Board) to value its investments wherever possible. Investments for which market quotations are not available or deemed not reliable are fair valued in good faith by the

Board's valuation designee.

U.S. generally accepted accounting principles (U.S. GAAP) establishes a disclosure hierarchy that categorizes the inputs to valuation techniques used to value assets and liabilities at measurement date. These inputs are summarized in the three broad levels listed below:

Level 1 - quoted prices in active markets for identical securities

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

Level 3 - significant unobservable inputs (including the Fund's own assumptions in determining the fair value of investments)

The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

Valuation techniques used to value the Fund's investments by major category are as follows:

**Equity Securities. Equity securities (including warrants and rights) listed on a U.S. securities exchange generally are valued at the last sale or closing price as reported by an independent pricing service on the primary market or exchange on which they are traded and are categorized as Level 1 in the hierarchy. Equity securities listed on the NASDAQ National Market System are valued at the NASDAQ official closing price and are categorized as Level 1 in the hierarchy. Unlisted or listed securities for which closing sales prices or closing quotations are not available are valued at the mean between the latest available bid and ask prices and are categorized as Level 2 in the hierarchy.**

**Debt Securities. Debt securities are generally valued based on 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. Accordingly, debt securities are generally categorized as Level 2 in the hierarchy. Short-term debt securities with a remaining maturity at time of purchase of more than sixty days are valued based on valuations provided by a third party pricing service. Such securities are generally categorized as Level 2 in the hierarchy. Short-term debt securities of sufficient credit quality purchased with remaining maturities 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, and are categorized as Level 2 in the hierarchy.**

**Other Securities. Investments in management investment companies (including money market funds) that do not trade on an exchange are valued at the net asset value as of the close of each business day and are categorized as Level 1 in the hierarchy.**

**Derivatives. Futures contracts are valued at unrealized appreciation (depreciation) based on the settlement price established each day by the board of trade or exchange on which they are traded and are categorized as Level 1 in the hierarchy. Forward foreign currency exchange contracts are generally valued at the mean of the average bid and average ask prices that are reported by currency dealers to a third party pricing service at the valuation time. Such third party pricing service valuations are supplied for specific settlement periods and the Fund's forward foreign currency exchange contracts are valued at an interpolated rate between the closest preceding and subsequent settlement period reported by the third party pricing service and are categorized as Level 2 in the hierarchy.**

**Fair Valuation. In connection with Rule 2a-5 of the 1940 Act, the Board has designated the 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 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 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.

The values assigned to fair value investments are based on available information and do not necessarily represent amounts that might ultimately be realized. Further, due to the inherent uncertainty of valuations of such investments, the fair values may differ significantly from the values that would have been used had an active market existed, and the differences could be material.

The following table summarizes the market value of the Fund's holdings as of March 31, 2026, based on the inputs used to value them:

B Investment Transactions and Income— Investment transactions for financial statement purposes are accounted for on trade date. Realized gains and losses are recorded on an identified cost basis and may include proceeds from litigation. Dividend income is recorded on the ex-dividend date for dividends received in cash and/or securities or, in the case of dividends on certain foreign securities, as soon as the Fund is informed of the ex-dividend date. Non-cash dividends are recorded at the fair value of the securities received. Withholding taxes on foreign dividends, if any, have been provided for in accordance with the Fund's understanding of the applicable country's tax rules and rates. Interest income, which includes amortization of premium and accretion of discount on debt securities, is accrued as earned.

C Share Class Accounting— Realized and unrealized gains and losses are allocated daily to each class of shares based upon the relative net assets of each class to the total net assets of the Fund. Net investment income, other than class-specific expenses, is allocated daily to each class of shares based upon the ratio of the value of each class's paid shares to the total value of all paid shares. Expenses arising in connection with a specific class are charged directly to that class. Sub-accounting, recordkeeping and similar administrative fees payable to financial intermediaries, which are a component of transfer agency fees and expenses on the Statement of Operations, are not allocated to Class R6 shares.

D Foreign Currency Transactions— The Fund's accounting records are maintained in U.S. dollars. For valuation of assets and liabilities on each date of net asset value determination, foreign denominations are converted into U.S. dollars using the current exchange rate. Security transactions, income and expenses are translated at the prevailing rate of exchange on the date of the event. Recognized gains or losses on investment transactions attributable to changes in foreign currency exchange rates are recorded for financial statement purposes as net realized gains and losses on investments. That portion of unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed.

E Futures Contracts— The Fund may enter into futures contracts to buy or sell a financial instrument for a set price at a future date. Initial margin deposits of either cash or securities as required by the broker are made upon entering into the contract. While the contract is open, daily variation margin payments are made to or received from the broker reflecting the daily change in market value of the contract and are recorded for financial reporting purposes as unrealized gains or losses by the Fund. When a futures contract is closed, a realized gain or loss is recorded equal to the difference between the opening and closing value of the contract. The risks associated with entering into futures contracts may include the possible illiquidity of the secondary market which would limit the Fund's ability to close out a futures contract prior to the settlement date, an imperfect correlation between the value of the contracts and the underlying financial instruments, or that the counterparty will fail to perform its obligations under the contracts' terms. Futures contracts are designed by boards of trade, which are designated "contracts markets" by the Commodities Futures Trading Commission. Futures contracts trade on the contracts markets in a manner that is similar to the way a stock trades on a stock exchange, and the boards of trade, through their clearing corporations, guarantee the futures contracts against default. As a result, there is minimal counterparty credit risk to the Fund.

F Forward Foreign Currency Exchange Contracts— The Fund may enter into forward foreign currency exchange contracts for the purchase or sale of a specific foreign currency at a fixed price on a future date. The forward foreign currency exchange contracts are adjusted by the daily exchange rate of the underlying currency and any gains or losses are recorded as unrealized until such time as the contracts have been closed. Risks may arise upon entering these contracts from the potential inability of counterparties to meet the terms of their contracts and from movements in the value of a foreign currency relative to the U.S. dollar.

G Restricted Securities— The Fund may invest in securities that are subject to legal or contractual restrictions on resale. Generally, these securities may only be sold publicly upon registration under the Securities Act of 1933 or in transactions exempt from such registration. Information regarding restricted securities (excluding Rule 144A securities) is included at the end of the Schedule of Investments.

H Distributions to Shareholders— Distributions to shareholders are recorded by the Fund on ex-dividend date. The Fund declares income distributions daily to shareholders of record at the time of declaration and generally pays them monthly. The Fund makes distributions of net realized capital gains, if any, at least annually. Distributions are declared separately for each class of shares. Distributions are determined in accordance with income tax regulations, which may differ from U.S. GAAP; accordingly, periodic reclassifications are made within the Fund's capital accounts to reflect income and gains available for distribution under income tax regulations.

I Estimates— The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates.

J Indemnifications— The Corporation's By-Laws provide for indemnification for Directors or officers of the Corporation and certain other parties, to the fullest extent permitted by Maryland law and the 1940 Act, provided certain conditions are met. Additionally, in the normal course of business, the Fund enters into agreements with service providers that may contain indemnification clauses. The Fund's maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Fund that have not yet occurred.

K Federal and Other Taxes— No provision for federal income or excise tax is required since the Fund intends to continue to qualify as a regulated investment company under the Internal Revenue Code and to distribute substantially all of its taxable earnings.

Management has analyzed the Fund's tax positions taken for all open federal income tax years and has concluded that no provision for federal income tax is required in the Fund's financial statements. A Fund's federal tax return is subject to examination by the Internal Revenue Service for a period of three years from the date of filing.

L Segment Reporting— The Fund operates as a single reportable segment, an investment company whose investment objective(s) is included in Note 1. The Fund's President acts as the Fund's Chief Operating Decision Maker (CODM), who is responsible for assessing the performance of the Fund's single segment and deciding how to allocate the segment's resources. To perform this function, the CODM reviews the information in the Fund's financial statements.

M Interim Financial Statements— The interim financial statements relating to March 31, 2026 and for the six months then ended have not been audited by an independent registered public accounting firm, but in the opinion of the Fund's management, reflect all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of the financial statements.

The Fund may invest in a money market fund, the Institutional Class of the Morgan Stanley Institutional Liquidity Funds - Government Portfolio (the "Liquidity Fund"), an open-end management investment company managed by Morgan Stanley Investment Management Inc., a wholly-owned subsidiary of Morgan Stanley. The investment advisory fee paid by the Fund is reduced by an amount equal to its pro rata share of the advisory and administration fees paid by the Fund due to its investment in the Liquidity Fund. For the six months ended March 31, 2026, the investment advisory fee paid was reduced by $32,463 relating to the Fund's investment in the Liquidity Fund.

CRM has agreed to reimburse the Fund's operating expenses to the extent that total annual operating expenses (relating to ordinary operating expenses only and excluding expenses such as brokerage commissions, acquired fund fees and expenses of unaffiliated funds, borrowing costs, taxes or litigation expenses) exceed 0.73%, 0.48% and 0.43% for Class A, Class I and Class R6, respectively, of such class's average daily net assets. The expense reimbursement agreement with CRM may be changed or terminated after February 1, 2027. For the six months ended March 31, 2026, CRM waived and/or reimbursed expenses of $169,784.

The administrative fee is earned by CRM as compensation for administrative services rendered to the Fund. The fee is computed at an annual rate of 0.12% of the Fund's average daily net assets attributable to Class A, Class I and Class R6 and is payable monthly. For the six months ended March 31, 2026, CRM was paid administrative fees of $498,728.

The Fund has in effect a distribution plan for Class A shares (Class A Plan) pursuant to Rule 12b-1 under the 1940 Act. Pursuant to the Class A Plan, the Fund pays Eaton Vance Distributors, Inc. (EVD), an affiliate of CRM and the Fund's principal underwriter, a distribution and service fee of 0.25% per annum of its average daily net assets attributable to Class A shares for distribution services and facilities provided to the Fund by EVD, as well as for personal services and/or the maintenance of shareholder accounts. Distribution and service fees paid or accrued for the six months ended March 31, 2026 amounted to $92,384 for Class A shares.

The Fund was informed that EVD received $4,180 as its portion of the sales charge on sales of Class A shares and no contingent deferred sales charges paid by Fund shareholders for the six months ended March 31, 2026.

Eaton Vance Management (EVM), an affiliate of CRM, provides sub-transfer agency and related services to the Fund pursuant to a Sub-Transfer Agency Support Services Agreement. For the six months ended March 31, 2026, sub-transfer agency fees and expenses incurred to EVM amounted to $7,590 and are included in transfer agency fees and expenses on the Statement of Operations.

Each Director of the Fund who is not an employee of CRM or its affiliates receives an annual fee of $250,000, an annual Committee fee ranging from $8,500 to $16,500 depending on the Committee, and may receive a fee of $10,000 for special meetings. The Board chair receives an additional $75,000 ($55,000 prior to January 1, 2026) annual fee, Committee chairs receive an additional $20,000 annual fee and the special equities liaison receives an additional $2,500 annual fee. Eligible Directors may participate in a Deferred Compensation Plan (the Plan). Amounts deferred under the Plan are treated as though equal dollar amounts had been invested in shares of the Fund or other Calvert funds selected by the Directors. The Fund purchases shares of the funds selected equal to the dollar amounts deferred under the Plan, resulting in an asset equal to the deferred compensation liability. Obligations of the Plan are paid solely from the Fund's assets. Directors' fees are allocated to each of the Calvert funds served. Salaries and fees of officers and Directors of the Fund who are employees of CRM or its affiliates are paid by CRM.

3 Investment Activity

During the six months ended March 31, 2026, the cost of purchases and proceeds from sales of investments, other than U.S. government and agency securities and short-term securities and including maturities and paydowns were $94,378,652 and $78,636,184, respectively. Purchases and sales of U.S. government and agency securities, including paydowns, were $53,561,735 and $19,895,158, respectively.

4 Distributions to Shareholders and Income Tax Information

At September 30, 2025, the Fund, for federal income tax purposes, had deferred capital losses of $73,132,045 which would reduce the 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 Fund of any liability for federal income or excise tax. The deferred capital losses are treated as arising on the first day of the Fund's next taxable year, can be carried forward for an unlimited period, and retain the same short-term or long-term character as when originally deferred. Of the deferred capital losses at September 30, 2025, $4,872,987 are short-term and $68,259,058 are long-term.

5 Financial Instruments

The Fund may trade in financial instruments with off-balance sheet risk in the normal course of its investing activities. These financial instruments may include forward foreign currency exchange contracts and futures contracts and may involve, to a varying degree, elements of risk in excess of the amounts recognized for financial statement purposes. The notional or contractual amounts of these instruments represent the investment the 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, 2026 is included in the Schedule of Investments. At March 31, 2026, the Fund had sufficient cash and/or securities to cover commitments under these contracts.

In the normal course of pursuing its investment objective, the Fund is subject to the following risks:

Foreign Exchange Risk: During the six months ended March 31, 2026, the Fund entered into forward foreign currency exchange contracts to seek to hedge against the decline in the value of currencies in which its portfolio holdings are denominated against the U.S. dollar and/or as a substitute for the purchase or sale of securities or currencies.

Interest Rate Risk: During the six months ended March 31, 2026, the Fund used futures contracts to hedge interest rate risk and to manage duration.

The Fund enters into over-the-counter (OTC) derivatives that may contain provisions whereby the counterparty may terminate the contract under certain conditions, including but not limited to a decline in the Fund's net assets below a certain level over a certain period of time, which would trigger a payment by the Fund for those derivatives in a liability position. At March 31, 2026, the fair value of derivatives with credit-related contingent features in a net liability position was $175,340. At March 31, 2026, there were no assets pledged by the Fund for such liability.

The OTC derivatives in which the Fund invests are subject to the risk that the counterparty to the contract fails to perform its obligations under the contract. To mitigate this risk, the Fund has entered into an International Swaps and Derivatives Association, Inc. Master Agreement ("ISDA Master Agreement") with its derivative counterparties. The ISDA Master Agreement is a bilateral agreement between the Fund and the counterparty that governs certain OTC derivatives and typically contains, among other things, set-off provisions in the event of a default and/or termination event as defined under the ISDA Master Agreement. Under the ISDA Master Agreement, the Fund may, under certain circumstances, offset with the counterparty certain derivative financial instruments' payables and/or receivables with collateral held and/or posted and create one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default including the bankruptcy or insolvency of the counterparty. However, bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset in bankruptcy or insolvency. Certain ISDA Master Agreements allow the counterparty to OTC derivatives to terminate derivative contracts prior to maturity in the event the Fund's net assets decline by a stated percentage or the Fund fails to meet the terms of its ISDA Master Agreements, which would cause the counterparty to accelerate payment by the Fund of any net liability owed to it.

The collateral requirements for derivatives traded under the ISDA Master Agreement are governed by a Credit Support Annex to the ISDA Master Agreement. Collateral requirements are determined at the close of business each day and are typically based on changes in market values for each transaction under the ISDA Master Agreement and netted into one amount for such agreement. Generally, the amount of collateral due from or to a counterparty is subject to a minimum transfer threshold amount before a transfer is required. Collateral pledged for the benefit of the Fund and/or counterparty is held in segregated accounts by the Fund's custodian and cannot be sold, re-pledged, assigned or otherwise used while pledged. The portion of such collateral representing cash, if any, is reflected as deposits for derivatives collateral and, in the case of cash pledged by a counterparty for the benefit of the Fund, a corresponding liability on the Statement of Assets and Liabilities. Securities pledged by the Fund as collateral, if any, are identified as such in the Schedule of Investments.

At March 31, 2026, the fair value of open derivative instruments (not considered to be hedging instruments for accounting disclosure purposes) by risk exposure was as follows:

---

&nbsp;&nbsp;&nbsp;&nbsp;

\* The average notional amount for forward foreign currency exchange contracts is based on the absolute value of notional amounts of currency purchased and currency sold.

6 Securities Lending

To generate additional income, the Fund may lend its securities pursuant to a securities lending agency agreement with State Street Bank and Trust Company (SSBT), the securities lending agent. Security loans are subject to termination by the Fund at any time and, therefore, are not considered illiquid investments. The Fund requires that the loan be continuously collateralized by either cash or securities in an amount at least equal to the market value of the securities on loan. The market value of securities loaned is determined daily and any additional required collateral is delivered to the Fund on the next business day. Cash collateral is generally invested in a money market fund registered under the 1940 Act that is managed by an affiliate of SSBT. Any gain or loss in the market price of the loaned securities that might occur and any interest earned or dividends declared during the term of the loan would accrue to the account of the Fund. Income earned on the investment of collateral, net of broker rebates and other expenses incurred by the securities lending agent, is split between the Fund and the securities lending agent based on agreed upon contractual terms. Non-cash collateral, if any, is held by the lending agent on behalf of the Fund and cannot be sold or re-pledged by the Fund; accordingly, such collateral is not reflected in the Statement of Assets and Liabilities.

The risks associated with lending portfolio securities include, but are not limited to, possible delays in receiving additional collateral or in the recovery of the loaned securities, possible loss of rights to the collateral should the borrower fail financially, as well as risk of loss in the value of the collateral or the value of the investments made with the collateral. The securities lending agent shall indemnify the Fund in the case of default of any securities borrower.

At March 31, 2026, the total value of securities on loan, including accrued interest, was $12,448,599 and the total value of collateral received was $12,809,602, comprised of cash of $8,449,643 and U.S. government and/or agencies securities of $4,359,959.

The following table provides a breakdown of securities lending transactions accounted for as secured borrowings, the obligations by class of collateral pledged, and the remaining contractual maturity of those transactions as of March 31, 2026.

The carrying amount of the liability for deposits for securities loaned at March 31, 2026 approximated its fair value. If measured at fair value, such liability would have been considered as Level 2 in the fair value hierarchy (see Note 1A) at March 31, 2026.

7 Line of Credit

The Fund participates with other portfolios and funds managed by EVM and its affiliates, including CRM, in a $650 million unsecured revolving line of credit agreement with a group of banks, which is in effect through October 20, 2026. Borrowings are made by the Fund solely for temporary purposes related to redemptions and other short-term cash needs. Interest is charged to the Fund based on its borrowings generally at an amount above either the Secured Overnight Financing Rate (SOFR) or Federal Funds rate. In addition, a fee computed at an annual rate of 0.15% on the daily unused portion of the line of credit is allocated among the participating portfolios and funds at the end of each quarter. In connection with the renewal of the agreement in October 2025, an arrangement fee of $150,000 was incurred that was allocated to the participating portfolios and funds. Because the line of credit is not available exclusively to the Fund, it may be unable to borrow some or all of its requested amounts at any particular time.

The Fund had no borrowings pursuant to its line of credit during the six months ended March 31, 2026.

8 Affiliated Investments

At March 31, 2026, the value of the Fund's investment in funds that may be deemed to be affiliated was $26,213,480, which represents 3.2% of the Fund's net assets. Transactions in such investments by the Fund for the six months ended March 31, 2026 were as follows:

10 Risks and Uncertainties

#### Risks Associated with Foreign Investments
Foreign investments can be adversely affected by political, economic and market developments abroad, including the imposition of economic and other sanctions by the United States or another country, and by acts of terrorism and war. There may be less publicly available information about foreign issuers because they may not be subject to reporting practices, requirements or regulations comparable to those to which United States companies are subject. Foreign markets may be smaller, less liquid and more volatile than the major markets in the United States. Trading in foreign markets typically involves higher expense than trading in the United States. The Fund may have difficulties enforcing its legal or contractual rights in a foreign country. Securities that trade or are denominated in currencies other than the U.S. dollar may be adversely affected by fluctuations in currency exchange rates.

Economic data as reported by sovereign entities may be delayed, inaccurate or fraudulent. In the event of a default by a sovereign entity, there are typically no assets to be seized or cash flows to be attached. Furthermore, the willingness or ability of a sovereign entity to restructure defaulted debt may be limited. Therefore, losses on sovereign defaults may far exceed the losses from the default of a similarly rated U.S. debt issuer.
