## How did the Fund perform last year and what affected its performance?
Key contributors to (↑) and detractors from (↓) performance, relative to the MSCI World ex USA Index (the Index):

↑ An out-of-Index position in Taiwan Semiconductor Manufacturing Co. contributed to returns as strong revenues were driven by surging demand for AI infrastructure chips

↑ An out-of-Index position in SK Hynix, Inc., a memory semiconductor firm, contributed to returns as it reported record second quarter revenue amid accelerating AI-memory demand

↑ Not owning Index component BHP Group Ltd., helped returns as weaker iron ore and coal prices and softer Chinese demand weighed on earnings expectations

↑ Among sectors, stock selection in information technology and stock selection and an underweight exposure to energy helped returns

↓ Not owning Index component firm Rheinmetall AG hurt returns as strong defense-business growth was offset by contract delays and margin pressure

↓ Not owning Index component and aerospace firm Rolls-Royce Holdings hurt returns as shares rallied on robust earnings growth, margin expansion, and higher engine output

↓ Not owning Index component Airbus SE hurt returns as the company delivered solid full-year 2024 results and strong order intake

↓ Among sectors, stock selection in the industrials, financials, and consumer staples sectors detracted from performance during the period

## Fund Performance
Comparison of the change in value of a $10,000 investment for the period indicated.

↑ An out-of-Index position in SK Hynix, Inc., a memory semiconductor firm, contributed to returns as it reported record second quarter revenue amid accelerating AI-memory demand

↑ Not owning Index component BHP Group Ltd., helped returns as weaker iron ore and coal prices and softer Chinese demand weighed on earnings expectations

↑ Among sectors, stock selection in information technology and stock selection and an underweight exposure to energy helped returns

↓ Not owning Index component firm Rheinmetall AG hurt returns as strong defense-business growth was offset by contract delays and margin pressure

↓ Not owning Index component and aerospace firm Rolls-Royce Holdings hurt returns as shares rallied on robust earnings growth, margin expansion, and higher engine output

↓ Not owning Index component Airbus SE hurt returns as the company delivered solid full-year 2024 results and strong order intake

↓ Among sectors, stock selection in the industrials, financials, and consumer staples sectors detracted from performance during the period

## How did the Fund perform last year and what affected its performance?
Key contributors to (↑) and detractors from (↓) performance, relative to the Russell 1000<sup>®</sup> Index (the Index):

↓ Not owning Index component Palantir Technologies, Inc. hurt returns, as shares rose sharply due to expanding AI-software contracts and accelerating commercial growth

↓ Not owning Index component and Facebook parent Meta Platforms, Inc also detracted as it generated double-digit total return amid AI and advertising segments momentum

↓ Among sectors, stock selection and an overweight position in healthcare, along with stock selection in consumer discretionary and information technology sectors, detracted

↑ Not owning Index component and energy major Exxon Mobil Corp. helped as shares lagged due to oil-price weakness and lower refining margins despite strong prior earnings

↑ Not owning Index component Berkshire Hathaway, Inc. contributed to returns as it under-performed the benchmark amid write-downs and slowed growth

↑An overweight position in Broadcom Inc. helped returns as it delivered strong results driven by its AI-networking business and robust semantic-software revenue growth

↑ Among sectors, an underweight position in energy and favorable stock selection in financials contributed to Index-relative returns

## How did the Fund perform last year and what affected its performance?
Key contributors to (↑) and detractors from (↓) performance, relative to the Russell 1000<sup>®</sup> Index (the Index):

↓ Not owning Index component Palantir Technologies, Inc. hurt returns, as shares rose sharply due to expanding AI-software contracts and accelerating commercial growth

↓ Not owning Index component and Facebook parent Meta Platforms, Inc also detracted as it generated double-digit total return amid AI and advertising segments momentum

↓ Among sectors, stock selection and an overweight position in healthcare, along with stock selection in consumer discretionary and information technology sectors, detracted

↑ Not owning Index component and energy major Exxon Mobil Corp. helped as shares lagged due to oil-price weakness and lower refining margins despite strong prior earnings

↑ Not owning Index component Berkshire Hathaway, Inc. contributed to returns as it under-performed the benchmark amid write-downs and slowed growth

↑An overweight position in Broadcom Inc. helped returns as it delivered strong results driven by its AI-networking business and robust semantic-software revenue growth

↑ Among sectors, an underweight position in energy and favorable stock selection in financials contributed to Index-relative returns

↓ Not owning Index component and Facebook parent Meta Platforms, Inc also detracted as it generated double-digit total return amid AI and advertising segments momentum

↓ Among sectors, stock selection and an overweight position in healthcare, along with stock selection in consumer discretionary and information technology sectors, detracted

↑ Not owning Index component and energy major Exxon Mobil Corp. helped as shares lagged due to oil-price weakness and lower refining margins despite strong prior earnings

↑ Not owning Index component Berkshire Hathaway, Inc. contributed to returns as it under-performed the benchmark amid write-downs and slowed growth

↑An overweight position in Broadcom Inc. helped returns as it delivered strong results driven by its AI-networking business and robust semantic-software revenue growth

↑ Among sectors, an underweight position in energy and favorable stock selection in financials contributed to Index-relative returns

## How did the Fund perform last year and what affected its performance?
Key contributors to (↑) and detractors from (↓) performance, relative to the Russell 1000<sup><sup>®</sup></sup> Growth Index (the Index):

↓ Not owning Index component Palantir Technologies, Inc. hampered returns as its stock surged on large AI-software contracts and strong Q2 2025 growth

↓ An underweight position in Tesla, Inc. hurt returns as it posted strong gains over 12 months, driven by robust EV deliveries and AI/autonomous-driving momentum

↓ An overweight position in UnitedHealth Group, Inc. detracted from performance as guidance cuts and rising medical-cost pressures weighed on its share price

↓ Among sectors, stock selection and an underweight position in information technology, and stock selection and an overweight position in healthcare hurt

↑ An underweight position in Apple Inc. aided returns as shares lagged broader technology peers due to moderating iPhone demand and subdued hardware sales growth

↑ An underweight position in Alphabet, Inc., Google's parent firm, helped returns amid investor concerns over rising AI infrastructure costs and softer advertising growth

↑ An underweight position in Microsoft Corp. also contributed as shares posted modest gains amid normalized cloud growth and persistent valuation pressures

↑ Among sectors, an underweight position in energy helped relative returns during the period

## How did the Fund perform last year and what affected its performance?
Key contributors to (↑) and detractors from (↓) performance, relative to the Russell 1000<sup><sup>®</sup></sup> Growth Index (the Index):

↓ Not owning Index component Palantir Technologies, Inc. hampered returns as its stock surged on large AI-software contracts and strong Q2 2025 growth

↓ An underweight position in Tesla, Inc. hurt returns as it posted strong gains over 12 months, driven by robust EV deliveries and AI/autonomous-driving momentum

↓ An overweight position in UnitedHealth Group, Inc. detracted from performance as guidance cuts and rising medical-cost pressures weighed on its share price

↓ Among sectors, stock selection and an underweight position in information technology, and stock selection and an overweight position in healthcare hurt

↑ An underweight position in Apple Inc. aided returns as shares lagged broader technology peers due to moderating iPhone demand and subdued hardware sales growth

↑ An underweight position in Alphabet, Inc., Google's parent firm, helped returns amid investor concerns over rising AI infrastructure costs and softer advertising growth

↑ An underweight position in Microsoft Corp. also contributed as shares posted modest gains amid normalized cloud growth and persistent valuation pressures

↑ Among sectors, an underweight position in energy helped relative returns during the period

## How did the Fund perform last year and what affected its performance?
Key contributors to (↑) and detractors from (↓) performance, relative to the Russell 1000<sup><sup>®</sup></sup> Growth Index (the Index):

↓ Not owning Index component Palantir Technologies, Inc. hampered returns as its stock surged on large AI-software contracts and strong Q2 2025 growth

↓ An underweight position in Tesla, Inc. hurt returns as it posted strong gains over 12 months, driven by robust EV deliveries and AI/autonomous-driving momentum

↓ An overweight position in UnitedHealth Group, Inc. detracted from performance as guidance cuts and rising medical-cost pressures weighed on its share price

↓ Among sectors, stock selection and an underweight position in information technology, and stock selection and an overweight position in healthcare hurt

↑ An underweight position in Apple Inc. aided returns as shares lagged broader technology peers due to moderating iPhone demand and subdued hardware sales growth

↑ An underweight position in Alphabet, Inc., Google's parent firm, helped returns amid investor concerns over rising AI infrastructure costs and softer advertising growth

↑ An underweight position in Microsoft Corp. also contributed as shares posted modest gains amid normalized cloud growth and persistent valuation pressures

↑ Among sectors, an underweight position in energy helped relative returns during the period

## How did the Fund perform last year and what affected its performance?
Key contributors to (↑) and detractors from (↓) performance, relative to the Russell 1000<sup><sup>®</sup></sup> Value Index (the Index):

↑ An underweight position in UnitedHealth Group, Inc. contributed as shares underperformed due to rising medical-cost pressures and operational headwinds

↑ An overweight position in JPMorgan Chase & Co. helped as it delivered record annual profits driven by strong investment-banking and markets revenue

↑ An overweight position in Goldman Sachs Group, Inc. helped as stronger advisory and trading activity in 2025 supported earnings growth

↑ Among sectors, stock selection and an overweight in financials, stock selection in information technology, and an underweight to healthcare helped returns

↓ Not owning Index component and Google's parent company Alphabet, Inc. hurt returns as shares gained on strong AI and cloud momentum, driving double-digit growth

↓ Not owning Index component and financials firm Robinhood Markets, Inc. hampered returns as the firm turned profitable and posted strong revenue growth in 2024

↓ Not owning Index component and leading tobacco firm Philip Morris International, Inc. hurt returns as strong full-year results and organic revenue growth in 2024 lifted its stocks

↓ Among sectors, stock selection in communication services and consumer staples, and stock selection and an underweight position in industrials detracted

## How did the Fund perform last year and what affected its performance?
Key contributors to (↑) and detractors from (↓) performance, relative to the Russell Midcap<sup><sup>®</sup></sup> Index (the Index):

↓ Not owning Index component Palantir Technologies, Inc. hampered returns, as its shares gained strongly on AI-software contract wins and accelerated commercial growth

↓ Not owning Index component Robinhood Markets, Inc. hurt, as its stocks rallied with a return to profitability and increased retail and crypto trading activity

↓ Not owning Index component Strategy Inc. hurt, as the company outperformed due to strong software-subscription growth and favorable market positioning

↓ Among sectors, stock selection in information technology and financials, and stock selection and an overweight position in health care hampered returns

↑ An out-of-Index position in Snowflake Inc. aided returns as the company delivered strong product-revenue growth and expanded its enterprise customer base

↑ An out-of-Index position in data storage firm Seagate Technology Holdings PLC helped as robust high-capacity storage demand and supply-chain recovery boosted results

↑ An underweight position in D.R. Horton, Inc. aided returns, as housing affordability challenges and high financing costs weighed on new home orders

↑ Among sectors, an underweight position in materials helped Index-relative returns

## How did the Fund perform last year and what affected its performance?
Key contributors to (↑) and detractors from (↓) performance, relative to the Russell Midcap<sup><sup>®</sup></sup> Index (the Index):

↓ Not owning Index component Palantir Technologies, Inc. hampered returns, as its shares gained strongly on AI-software contract wins and accelerated commercial growth

↓ Not owning Index component Robinhood Markets, Inc. hurt, as its stocks rallied with a return to profitability and increased retail and crypto trading activity

↓ Not owning Index component Strategy Inc. hurt, as the company outperformed due to strong software-subscription growth and favorable market positioning

↓ Among sectors, stock selection in information technology and financials, and stock selection and an overweight position in health care hampered returns

↑ An out-of-Index position in Snowflake Inc. aided returns as the company delivered strong product-revenue growth and expanded its enterprise customer base

↑ An out-of-Index position in data storage firm Seagate Technology Holdings PLC helped as robust high-capacity storage demand and supply-chain recovery boosted results

↑ An underweight position in D.R. Horton, Inc. aided returns, as housing affordability challenges and high financing costs weighed on new home orders

↑ Among sectors, an underweight position in materials helped Index-relative returns

#### Item 2. Code of Ethics
The registrant (sometimes referred to as the "Fund") has adopted a code of ethics applicable to its Principal Executive Officer, Principal Financial Officer and Principal Accounting Officer. The registrant undertakes to provide a copy of such code of ethics to any person upon request, without charge, by calling 1-800-368-2745.

The registrant's Board of Directors has determined that Edward Ramos, an "independent" Director serving on the registrant's audit committee, is an "audit committee financial expert," as defined in Item 3 of Form N-CSR. Under applicable securities laws, a person who is determined to be an audit committee financial expert will not be deemed an "expert" for any purpose, including without limitation for the purposes of Section 11 of the Securities Act of 1933, as a result of being designated or identified as an audit committee financial expert. The designation or identification of a person as an audit committee financial expert does not impose on such person any duties, obligations, or liabilities that are greater than the duties, obligations, and liabilities imposed on such person as a member of the audit committee and Board of Directors in the absence of such designation or identification.

\* Percentage of fees approved by the Audit Committee pursuant to (c)(7)(i)(C) of Rule 2-01 of Reg. S-X (statutory de minimis waiver of Committee's requirement to pre-approve). 

<sup>(1)</sup> Audit-related fees consist of the aggregate fees billed for assurance and related services that are reasonably related to the performance of the audit of the registrant's financial statements and are not reported under the category of audit fees.

<sup>(2)</sup> Tax fees consist of the aggregate fees billed for professional services rendered by the principal accountant relating to tax compliance, tax advice, and tax planning and specifically include fees for tax return preparation and other related tax compliance/planning matters.

<sup>(3)</sup> All other fees consist of the aggregate fees billed for products and services provided by the principal accountant other than audit, audit-related, and tax services.

(e) The Audit Committee is required to pre-approve all audit and non-audit services provided to the registrant by the auditors, and to the registrant's investment adviser, and any entity controlling, controlled by, or under common control with the adviser that provides ongoing services to the registrant. In determining whether to pre-approve non-audit services, the Audit Committee considers whether the services are consistent with maintaining the independence of the auditors. The Committee may delegate its authority to pre-approve certain matters to one or more of its members. In this regard, the Committee has delegated authority jointly to the Audit Committee Chair together with another Committee member with respect to non-audit services not exceeding $25,000 in each instance. In addition, the Committee has pre-approved the retention of the auditors to provide tax-related services related to the tax treatment and tax accounting of newly acquired securities, upon request by the investment adviser in each instance.

\* Percentage of fees approved by the Audit Committee pursuant to (c)(7)(i)(C) of Rule 2-01 of Reg. S-X (statutory de minimis waiver of Committee's requirement to pre-approve). 

(h) The registrant's audit committee has considered whether the provision by the registrant's principal accountant of non-audit services to the registrant's investment adviser and any entity controlling, controlled by, or under common control with the adviser that provides ongoing services to the registrant that were not pre-approved pursuant to Rule 2-01(c)(7)(ii) of Regulation S-X is compatible with maintaining the principal accountant's independence.

(i) Not applicable.

1 Significant Accounting Policies

Calvert US Large-Cap Growth Responsible Index Fund (the Fund) is a diversified series of Calvert Responsible Index Series, 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 track the performance of the Calvert US Large-Cap Growth Responsible Index, which measures the investment return of large-capitalization stocks.

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 0.25% 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.**

**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> None of the unobservable inputs for Level 3 assets, individually or collectively, had a material impact on the Fund. <br> <sup>(2)</sup> The level classification by major category of investments is the same as the category presentation in the Schedule of Investments.

Level 3 investments at the beginning and/or end of the period in relation to net assets were not significant and accordingly, a reconciliation of Level 3 assets for the year ended September 30, 2025 is not presented.

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 Foreign Currency Translation— Other assets and liabilities initially expressed in foreign currencies are translated each business day into U.S. dollars based upon current exchange rates. Income and expenses denominated in foreign currencies are translated into U.S. dollars based upon currency exchange rates in effect on the respective dates of such transactions.

D 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.

E 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.

F 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.

G 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.

H 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.

I Federal Income 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.

J Segment Reporting— During this reporting period, the Fund adopted FASB Accounting Standards Update No. 2023-07, *Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures* (ASU 2023-07), which requires incremental disclosures related to a public entity's reportable

segments. The Fund operates as a single reportable segment, an investment company whose investment objective(s) is included in Note 1. In connection with the adoption of ASU 2023-07, 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.

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 0.12% of the Fund's average daily net assets and is payable monthly. For the year ended September 30, 2025, the investment advisory fee amounted to $857,339.

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 year ended September 30, 2025, the investment advisory fee paid was reduced by $1,173 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 0.49%, 0.24% and 0.21% 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, 2026. For the year ended September 30, 2025, CRM waived and/or reimbursed expenses of $1,010,496.

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 year ended September 30, 2025, CRM was paid administrative fees of $857,339.

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 year ended September 30, 2025 amounted to $290,864 for Class A shares.

The Fund was informed that EVD received $27,192 as its portion of the sales charge on sales of Class A shares for the year ended September 30, 2025. The Fund was also informed that EVD received $106 of contingent deferred sales charges paid by Class A shareholders 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 year ended September 30, 2025, sub-transfer agency fees and expenses incurred to EVM amounted to $20,501 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 $55,000 ($40,000 prior to January 1, 2025) annual fee, Committee chairs receive an additional $20,000 ($15,000 prior to January 1, 2025) 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 year ended September 30, 2025, the cost of purchases and proceeds from sales of investments, other than short-term securities, were $216,115,298 and $247,665,322, respectively.

4 Distributions to Shareholders and Income Tax Information

The tax character of distributions declared for the years ended September 30, 2025 and September 30, 2024 was as follows:

---

| | | |
|:---|:---|:---|
|  | &nbsp;&nbsp;&nbsp;&nbsp;**Year Ended September 30,** | &nbsp;&nbsp;&nbsp;&nbsp;**Year Ended September 30,** |
|  | &nbsp;&nbsp;&nbsp;&nbsp;**2025** | &nbsp;&nbsp;&nbsp;&nbsp;**2024** |
| Ordinary income | &nbsp;&nbsp;&nbsp;&nbsp;$4412363 | &nbsp;&nbsp;&nbsp;&nbsp;$2974609 |
| Long-term capital gains | &nbsp;&nbsp;&nbsp;&nbsp;$9970640 | &nbsp;&nbsp;&nbsp;&nbsp;$— |

---

During the year ended September 30, 2025, distributable earnings was decreased by $2,101,385 and paid-in capital was increased by $2,101,385 due to the Fund's use of equalization accounting. Tax equalization accounting allows the Fund to treat as a distribution that portion of redemption proceeds representing a redeeming shareholder's portion of undistributed taxable income and net capital gains. These reclassifications had no effect on the net assets or net asset value per share of the Fund.

As of September 30, 2025, the components of distributable earnings (accumulated loss) on a tax basis were as follows:

---

| | |
|:---|:---|
| Undistributed ordinary income | &nbsp;&nbsp;&nbsp;&nbsp;$5598333 |
| Undistributed long-term capital gains | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;16203875 |
| Net unrealized appreciation | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;375705294 |
| **Distributable earnings** | &nbsp;&nbsp;&nbsp;&nbsp;**$397507502** |

The cost and unrealized appreciation (depreciation) of investments of the Fund at September 30, 2025, as determined on a federal income tax basis, were as follows:

---

| | |
|:---|:---|
| **Aggregate cost** | &nbsp;&nbsp;&nbsp;&nbsp;**$399442963** |
| Gross unrealized appreciation | &nbsp;&nbsp;&nbsp;&nbsp;$379754030 |
| Gross unrealized depreciation | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4048736) |
| **Net unrealized appreciation** | &nbsp;&nbsp;&nbsp;&nbsp;**$375705294** |

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 September 30, 2025, the total value of securities on loan was $1,813,722 and the total value of collateral received was $1,850,637, comprised of cash of $473,726 and U.S. government and/or agencies securities of $1,376,911.

The carrying amount of the liability for deposits for securities loaned at September 30, 2025 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 September 30, 2025.

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 21, 2025. 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 2024, 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 September 30, 2025. The Fund did not have any significant borrowings or allocated fees during the year ended September 30, 2025. Effective October 21, 2025, the Fund renewed its line of credit agreement, which expires October 20, 2026, at substantially the same terms.

7 Affiliated Investments

At September 30, 2025, the value of the Fund's investment in funds that may be deemed to be affiliated was $1,718,172, which represents 0.2% of the Fund's net assets. Transactions in such investments by the Fund for the year ended September 30, 2025 were as follows:

Report of Independent Registered Public Accounting Firm

------

To the Shareholders of Calvert US Large-Cap Growth Responsible Index Fund and Board of Directors of Calvert Responsible Index Series, Inc.:

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Calvert US Large-Cap Growth Responsible Index Fund (the "Fund"), one of the funds constituting Calvert Responsible Index Series, Inc., as of September 30, 2025, the related statement of operations for the year then ended, statements of changes in net assets for each of the two years in the period then ended, financial highlights for each of the five years in the period then ended, and the related notes (collectively referred to as the "financial statements and financial highlights"). In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of September 30, 2025, and the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on the Fund's financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. Our procedures included confirmation of securities owned as of September 30, 2025, by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

Board of Directors' Contract Approval

------

Overview of the Contract Review Process

The Investment Company Act of 1940, as amended, provides, in substance, that each investment advisory agreement between a fund and its investment adviser will continue in effect from year to year only if its continuation is approved at least annually by the fund's board of directors, including by a vote of a majority of the directors who are not "interested persons" of the fund ("Independent Directors"), cast in person at a meeting called for the purpose of considering such approval.

At an in-person meeting of the Boards of Trustees/Directors (each a "Board") of the registered investment companies advised by Calvert Research and Management ("CRM" or the "Adviser") (the "Calvert Funds") held on June 9-10, 2025, the Board, including a majority of the Independent Directors, voted to approve continuation of existing investment advisory and investment sub-advisory agreements for the Calvert Funds for an additional one-year period.

In evaluating the investment advisory and investment sub-advisory agreements for the Calvert Funds, the Board considered a variety of information relating to the Calvert Funds and various service providers, including the Adviser. The Independent Directors reviewed a report prepared by the Adviser regarding various services provided to the Calvert Funds by the Adviser and its affiliates. Such report included, among other data, information regarding the Adviser's personnel and the Adviser's revenue and cost of providing services to the Calvert Funds, and a separate report prepared by an independent data provider, which compared each fund's investment performance, fees and expenses to those of comparable funds as identified by such independent data provider ("comparable funds").

The Independent Directors were separately represented by independent legal counsel with respect to their consideration of the continuation of the investment advisory and investment sub-advisory agreements for the Calvert Funds. Prior to voting, the Independent Directors reviewed the proposed continuation of the Calvert Funds' investment advisory and investment sub-advisory agreements with management and also met in private sessions with their counsel at which time no representatives of management were present.

The information that the Board considered included, among other things, the following (for funds that invest through one or more affiliated underlying fund(s), references to "each fund" in this section may include information that was considered at the underlying fund-level):

*Information about Fees, Performance and Expenses*

• A report from an independent data provider comparing the advisory and related fees paid by each fund with fees paid by comparable funds;

• A report from an independent data provider comparing each fund's total expense ratio and its components to comparable funds;

• A report from an independent data provider comparing the investment performance of each fund to the investment performance of comparable funds over various time periods;

• Data regarding investment performance in comparison to benchmark indices;

• For each fund, comparative information concerning the fees charged and the services provided by the Adviser in managing other accounts (including mutual funds, other collective investment funds and institutional accounts) using investment strategies and techniques similar to those used in managing such fund;

• Profitability analyses for the Adviser with respect to each fund;

*Information about Portfolio Management and Trading*

• Descriptions of the investment management services provided to each fund, including investment strategies and processes it employs;

• Information about the Adviser's policies and practices with respect to trading, including the Adviser's processes for monitoring best execution of portfolio transactions;

• Information about the allocation of brokerage transactions and the benefits received by the Adviser as a result of brokerage allocation, including information concerning the acquisition of research through client commission arrangements and policies with respect to "soft dollars";

*Information about the Adviser*

• Reports detailing the financial results and condition of CRM;

• Descriptions of the qualifications, education and experience of the individual investment professionals whose responsibilities include portfolio management and investment research for the funds, and information relating to their compensation and responsibilities with respect to managing other mutual funds and investment accounts;

• Policies and procedures relating to proxy voting and the handling of corporate actions and class actions;

• A description of CRM's procedures for overseeing sub-advisers, including with respect to regulatory and compliance issues, investment management and other matters;

Board of Directors' Contract Approval — continued

------

*Other Relevant Information*

• Information concerning the nature, cost and character of the administrative and other non-investment advisory services provided by CRM and its affiliates; and

• The terms of each investment advisory agreement.

Over the course of the year, the Board and its committees held regular quarterly meetings. During these meetings, the Directors participated in investment and performance reviews with the portfolio managers and other investment professionals of the Adviser relating to each fund and considered various investment and trading strategies used in pursuing each fund's investment objective(s), such as the use of derivative instruments, as well as risk management techniques. The Board and its committees also evaluated issues pertaining to industry and regulatory developments, compliance procedures, corporate governance and other issues with respect to the funds and received and participated in reports and presentations provided by CRM and its affiliates with respect to such matters. In addition to the formal meetings of the Board and its committees, the Independent Directors held regular video conferences in between meetings to discuss, among other topics, matters relating to the continuation of the Calvert Funds' investment advisory and investment sub-advisory agreements.

For funds that invest through one or more affiliated underlying funds, the Board considered similar information about the underlying fund(s) when considering the approval of investment advisory agreements. In addition, in cases where the Adviser has engaged a sub-adviser, the Board considered similar information about the sub-adviser when considering the approval of any investment sub-advisory agreement.

The Independent Directors were assisted throughout the contract review process by their independent legal counsel. The Independent Directors relied upon the advice of such counsel and their own business judgment in determining the material factors to be considered in evaluating each investment advisory and investment sub-advisory agreement and the weight to be given to each such factor. The Board, including the Independent Directors, did not identify any single factor as controlling, and each Director may have attributed different weight to various factors.

Results of the Contract Review Process

Based on its consideration of the foregoing, and such other information as it deemed relevant, including the factors and conclusions described below, the Board, including the Independent Directors, concluded that the continuation of the investment advisory agreement of Calvert US Large-Cap Growth Responsible Index Fund (the "Fund"), including the fee payable under the agreement, is in the best interests of the Fund's shareholders. Accordingly, the Board, including a majority of the Independent Directors, voted to approve the continuation of the investment advisory agreement of the Fund.

Nature, Extent and Quality of Services

In considering the nature, extent and quality of the services provided by the Adviser under the investment advisory agreement, the Board reviewed information provided by the Adviser relating to its operations and personnel, including, among other information, biographical information on the Adviser's investment personnel and descriptions of its organizational and management structure. The Board also took into account similar information provided periodically throughout the previous year by the Adviser as well as the Board's familiarity with management through Board meetings, discussions and other reports. The Board considered the Adviser's management style and its performance in employing its investment strategies as well as its current level of staffing and overall resources. The Board also noted that it reviewed on a quarterly basis information regarding the Adviser's compliance with applicable policies and procedures, including those related to personal investing. The Board took into account, among other items, periodic reports received from the Adviser over the past year concerning the Adviser's ongoing review and enhancement of certain processes, policies and procedures of the Calvert Funds and the Adviser. The Board concluded that it was satisfied with the nature, extent and quality of services provided to the Fund by the Adviser under the investment advisory agreement.

Fund Performance

In considering the Fund's performance, the Board noted that it reviewed on a quarterly basis detailed information about the Fund's performance results, portfolio composition and investment strategies. The Board compared the Fund's investment performance to that of the Fund's peer universe and the index it is designed to track. The Board's review included comparative performance data for the one-, three- and five-year periods ended December 31, 2024. This performance data indicated that the Fund had underperformed the median of the Fund's peer universe for the one-year period ended December 31, 2024, while it had outperformed the median of its peer universe for the three- and five-year periods ended December 31, 2024. This data also indicated that the Fund had underperformed the index it is designed to track for the one-, three- and five-year periods ended December 31, 2024. Based upon its review, the Board concluded that the Fund's performance was satisfactory relative to the performance of its peer universe and the index it is designed to track.

Management Fees and Expenses

In considering the Fund's fees and expenses, the Board compared the Fund's fees and total expense ratio with those of comparable funds in its expense group. Among other findings, the data indicated that the Fund's advisory and administrative fees (after taking into account waivers and/or reimbursements) (referred to collectively as "management fees") and the Fund's total expenses (net of waivers and/or reimbursements) were each below the respective median of the Fund's expense group. The Board took into account the Adviser's current undertaking to maintain expense limitations for the Fund and that the Adviser had waived or reimbursed a portion of the Fund's expenses. Based upon its review, the Board concluded that the management fees were reasonable in view of the nature, extent and quality of services provided by the Adviser.

Profitability and Other "Fall-Out" Benefits

The Board reviewed the Adviser's profitability in regard to the Fund and the Calvert Funds in the aggregate. In reviewing the overall profitability of the Fund to the Adviser, the Board also considered the fact that the Adviser and its affiliates provided sub-transfer agency support, administrative and distribution services to the Fund for which they received compensation. The information considered by the Board included the profitability of the Fund to the Adviser and its affiliates without regard to any marketing support or other payments by the Adviser and its affiliates to third parties in respect of distribution services. The Board also considered that the Adviser and its affiliates derived benefits to their reputation and other indirect benefits from their relationships with the Fund. Based upon its review, the Board concluded that the Adviser's and its affiliates' level of profitability from their relationships with the Fund was reasonable.

Economies of Scale

The Board considered the effect of the Fund's current size and its potential growth on its performance and fees. The Board concluded that adding breakpoints to the advisory fee at specified asset levels was not necessary at this time. The Board noted that if the Fund's assets increased over time, the Fund might realize other economies of scale if assets increased proportionally more than certain other expenses.

International Responsible Index Fund

1 Significant Accounting Policies

Calvert International Responsible Index Fund (the Fund) is a diversified series of Calvert Responsible Index Series, 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 track the performance of the Calvert International Responsible Index, which measures the investment return of stocks issued by companies that are located in countries (other than the U.S.) with developed markets.

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 0.25% 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. 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 Fund's 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 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> Includes foreign equity securities whose values were adjusted to reflect market trading of comparable securities or other correlated instruments that occurred after the close of trading in their applicable foreign markets.

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. 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 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 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.

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, 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.

H Federal Income 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.

I Segment Reporting— During this reporting period, the Fund adopted FASB Accounting Standards Update No. 2023-07, *Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures* (ASU 2023-07), which requires incremental disclosures related to a public entity's reportable segments. The Fund operates as a single reportable segment, an investment company whose investment objective(s) is included in Note 1. In connection with the adoption of ASU 2023-07, 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.

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 0.12% of the Fund's average daily net assets and is payable monthly. For the year ended September 30, 2025, the investment advisory fee amounted to $1,387,937.

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 year ended September 30, 2025, the investment advisory fee paid was reduced by $2,317 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 0.54%, 0.29% and 0.26% 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, 2026. For the year ended September 30, 2025, CRM waived and/or reimbursed expenses of $928,224.

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 year ended September 30, 2025, CRM was paid administrative fees of $1,387,937.

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 year ended September 30, 2025 amounted to $252,444 for Class A shares.

The Fund was informed that EVD received $8,860 as its portion of the sales charge on sales of Class A shares for the year ended September 30, 2025. The Fund was also informed that EVD received no contingent deferred sales charges paid by Class A shareholders 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 year ended September 30, 2025, sub-transfer agency fees and expenses incurred to EVM amounted to $21,907 and are included in transfer agency fees and expenses on the Statement of Operations.

During the year ended September 30, 2025, CRM reimbursed the Fund $109,341 for a net realized loss due to a trading error. The impact of the reimbursement was less than $0.01 per share for each class and had no significant impact on total return.

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 $55,000 ($40,000 prior to January 1, 2025) annual fee, Committee chairs receive an additional $20,000 ($15,000 prior to January 1, 2025) 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 year ended September 30, 2025, the cost of purchases and proceeds from sales of investments, other than short-term securities, were $195,214,968 and $187,104,496, respectively.

4 Distributions to Shareholders and Income Tax Information

The tax character of distributions declared for the years ended September 30, 2025 and September 30, 2024 was as follows:

---

| | | |
|:---|:---|:---|
|  | &nbsp;&nbsp;&nbsp;&nbsp;**Year Ended September 30,** | &nbsp;&nbsp;&nbsp;&nbsp;**Year Ended September 30,** |
|  | &nbsp;&nbsp;&nbsp;&nbsp;**2025** | &nbsp;&nbsp;&nbsp;&nbsp;**2024** |
| Ordinary income | &nbsp;&nbsp;&nbsp;&nbsp;$29351758 | &nbsp;&nbsp;&nbsp;&nbsp;$18407305 |

---

During the year ended September 30, 2025, distributable earnings was decreased by $3,481,793 and paid-in capital was increased by $3,481,793 due to the Fund's use of equalization accounting. Tax equalization accounting allows the Fund to treat as a distribution that portion of redemption proceeds representing a redeeming shareholder's portion of undistributed taxable income and net capital gains. These reclassifications had no effect on the net assets or net asset value per share of the Fund.

As of September 30, 2025, the components of distributable earnings (accumulated loss) on a tax basis were as follows:

---

| | |
|:---|:---|
| Undistributed ordinary income | &nbsp;&nbsp;&nbsp;&nbsp;$39759275 |
| Deferred capital losses | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(31489998) |
| Net unrealized appreciation | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;342459627 |
| **Distributable earnings** | &nbsp;&nbsp;&nbsp;&nbsp;**$350728904** |

---

At September 30, 2025, the Fund, for federal income tax purposes, had deferred capital losses of $31,489,998 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, $14,236,876 are short-term and $17,253,122 are long-term.

The cost and unrealized appreciation (depreciation) of investments of the Fund at September 30, 2025, as determined on a federal income tax basis, were as follows:

---

| | |
|:---|:---|
| **Aggregate cost** | &nbsp;&nbsp;&nbsp;&nbsp;**$962646260** |
| Gross unrealized appreciation | &nbsp;&nbsp;&nbsp;&nbsp;$381246865 |
| Gross unrealized depreciation | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(39072092) |
| **Net unrealized appreciation** | &nbsp;&nbsp;&nbsp;&nbsp;**$342174773** |

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 September 30, 2025, the total value of securities on loan was $47,523,558 and the total value of collateral received was $49,787,024, comprised of cash of $14,005,700 and U.S. government and/or agencies securities of $35,781,324.

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 September 30, 2025.

The carrying amount of the liability for deposits for securities loaned at September 30, 2025 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 September 30, 2025.

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 21, 2025. 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 2024, 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.

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 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.

Report of Independent Registered Public Accounting Firm

------

To the Shareholders of Calvert International Responsible Index Fund and Board of Directors of Calvert Responsible Index Series, Inc.:

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Calvert International Responsible Index Fund (the "Fund"), one of the funds constituting Calvert Responsible Index Series, Inc., as of September 30, 2025, the related statement of operations for the year then ended, statements of changes in net assets for each of the two years in the period then ended, financial highlights for each of the five years in the period then ended, and the related notes (collectively referred to as the "financial statements and financial highlights"). In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of September 30, 2025, and the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on the Fund's financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. Our procedures included confirmation of securities owned as of September 30, 2025, by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

Board of Directors' Contract Approval

------

Overview of the Contract Review Process

The Investment Company Act of 1940, as amended, provides, in substance, that each investment advisory agreement between a fund and its investment adviser will continue in effect from year to year only if its continuation is approved at least annually by the fund's board of directors, including by a vote of a majority of the directors who are not "interested persons" of the fund ("Independent Directors"), cast in person at a meeting called for the purpose of considering such approval.

At an in-person meeting of the Boards of Trustees/Directors (each a "Board") of the registered investment companies advised by Calvert Research and Management ("CRM" or the "Adviser") (the "Calvert Funds") held on June 9-10, 2025, the Board, including a majority of the Independent Directors, voted to approve continuation of existing investment advisory and investment sub-advisory agreements for the Calvert Funds for an additional one-year period.

In evaluating the investment advisory and investment sub-advisory agreements for the Calvert Funds, the Board considered a variety of information relating to the Calvert Funds and various service providers, including the Adviser. The Independent Directors reviewed a report prepared by the Adviser regarding various services provided to the Calvert Funds by the Adviser and its affiliates. Such report included, among other data, information regarding the Adviser's personnel and the Adviser's revenue and cost of providing services to the Calvert Funds, and a separate report prepared by an independent data provider, which compared each fund's investment performance, fees and expenses to those of comparable funds as identified by such independent data provider ("comparable funds").

The Independent Directors were separately represented by independent legal counsel with respect to their consideration of the continuation of the investment advisory and investment sub-advisory agreements for the Calvert Funds. Prior to voting, the Independent Directors reviewed the proposed continuation of the Calvert Funds' investment advisory and investment sub-advisory agreements with management and also met in private sessions with their counsel at which time no representatives of management were present.

The information that the Board considered included, among other things, the following (for funds that invest through one or more affiliated underlying fund(s), references to "each fund" in this section may include information that was considered at the underlying fund-level):

*Information about Fees, Performance and Expenses*

*•* *A report from an independent data provider comparing the advisory and related fees paid by each fund with fees paid by comparable funds;* 

• A report from an independent data provider comparing each fund's total expense ratio and its components to comparable funds;

• A report from an independent data provider comparing the investment performance of each fund to the investment performance of comparable funds over various time periods;

• Data regarding investment performance in comparison to benchmark indices;

• For each fund, comparative information concerning the fees charged and the services provided by the Adviser in managing other accounts (including mutual funds, other collective investment funds and institutional accounts) using investment strategies and techniques similar to those used in managing such fund;

• Profitability analyses for the Adviser with respect to each fund;

*Information about Portfolio Management and Trading*

• Descriptions of the investment management services provided to each fund, including investment strategies and processes it employs;

• Information about the Adviser's policies and practices with respect to trading, including the Adviser's processes for monitoring best execution of portfolio transactions;

• Information about the allocation of brokerage transactions and the benefits received by the Adviser as a result of brokerage allocation, including information concerning the acquisition of research through client commission arrangements and policies with respect to "soft dollars";

*Information about the Adviser*

• Reports detailing the financial results and condition of CRM;

• Descriptions of the qualifications, education and experience of the individual investment professionals whose responsibilities include portfolio management and investment research for the funds, and information relating to their compensation and responsibilities with respect to managing other mutual funds and investment accounts;

• Policies and procedures relating to proxy voting and the handling of corporate actions and class actions;

• A description of CRM's procedures for overseeing sub-advisers, including with respect to regulatory and compliance issues, investment management and other matters;

*Other Relevant Information*

• Information concerning the nature, cost and character of the administrative and other non-investment advisory services provided by CRM and its affiliates; and

• The terms of each investment advisory agreement.

Over the course of the year, the Board and its committees held regular quarterly meetings. During these meetings, the Directors participated in investment and performance reviews with the portfolio managers and other investment professionals of the Adviser relating to each fund and considered various investment and trading strategies used in pursuing each fund's investment objective(s), such as the use of derivative instruments, as well as risk management techniques. The Board and its committees also evaluated issues pertaining to industry and regulatory developments, compliance procedures, corporate governance and other issues with respect to the funds and received and participated in reports and presentations provided by CRM and its affiliates with respect to such matters. In addition to the formal meetings of the Board and its committees, the Independent Directors held regular video conferences in between meetings to discuss, among other topics, matters relating to the continuation of the Calvert Funds' investment advisory and investment sub-advisory agreements.

For funds that invest through one or more affiliated underlying funds, the Board considered similar information about the underlying fund(s) when considering the approval of investment advisory agreements. In addition, in cases where the Adviser has engaged a sub-adviser, the Board considered similar information about the sub-adviser when considering the approval of any investment sub-advisory agreement.

The Independent Directors were assisted throughout the contract review process by their independent legal counsel. The Independent Directors relied upon the advice of such counsel and their own business judgment in determining the material factors to be considered in evaluating each investment advisory and investment sub-advisory agreement and the weight to be given to each such factor. The Board, including the Independent Directors, did not identify any single factor as controlling, and each Director may have attributed different weight to various factors.

Results of the Contract Review Process

Based on its consideration of the foregoing, and such other information as it deemed relevant, including the factors and conclusions described below, the Board, including the Independent Directors, concluded that the continuation of the investment advisory agreement of Calvert International Responsible Index Fund (the "Fund"), including the fee payable under the agreement, is in the best interests of the Fund's shareholders. Accordingly, the Board, including a majority of the Independent Directors, voted to approve the continuation of the investment advisory agreement of the Fund.

Nature, Extent and Quality of Services

In considering the nature, extent and quality of the services provided by the Adviser under the investment advisory agreement, the Board reviewed information provided by the Adviser relating to its operations and personnel, including, among other information, biographical information on the Adviser's investment personnel and descriptions of its organizational and management structure. The Board also took into account similar information provided periodically throughout the previous year by the Adviser as well as the Board's familiarity with management through Board meetings, discussions and other reports. The Board considered the Adviser's management style and its performance in employing its investment strategies as well as its current level of staffing and overall resources. The Board also noted that it reviewed on a quarterly basis information regarding the Adviser's compliance with applicable policies and procedures, including those related to personal investing. The Board took into account, among other items, periodic reports received from the Adviser over the past year concerning the Adviser's ongoing review and enhancement of certain processes, policies and procedures of the Calvert Funds and the Adviser. The Board concluded that it was satisfied with the nature, extent and quality of services provided to the Fund by the Adviser under the investment advisory agreement.

Fund Performance

In considering the Fund's performance, the Board noted that it reviewed on a quarterly basis detailed information about the Fund's performance results, portfolio composition and investment strategies. The Board compared the Fund's investment performance to that of the Fund's peer universe and the index it is designed to track. The Board's review included comparative performance data for the one-, three- and five-year periods ended December 31, 2024. This performance data indicated that the Fund had outperformed the median of its peer universe for the one- and five-year periods ended December 31, 2024, while it had underperformed the median of its peer universe for the three-year period ended December 31, 2024. This data also indicated that the Fund had underperformed the index it is designed to track for the one-, three- and five-year periods ended December 31, 2024. Based upon its review, the Board concluded that the Fund's performance was satisfactory relative to the performance of its peer universe and the index it is designed to track.

Management Fees and Expenses

In considering the Fund's fees and expenses, the Board compared the Fund's fees and total expense ratio with those of comparable funds in its expense group. Among other findings, the data indicated that the Fund's advisory and administrative fees (after taking into account waivers and/or reimbursements) (referred to collectively as "management fees") and the Fund's total expenses (net of waivers and/or reimbursements) were each below the respective median of the Fund's expense group. The Board took into account the Adviser's current undertaking to maintain expense limitations for the Fund and that the Adviser had waived or reimbursed a portion of the Fund's expenses. Based upon its review, the Board concluded that the management fees were reasonable in view of the nature, extent and quality of services provided by the Adviser.

Profitability and Other "Fall-Out" Benefits

The Board reviewed the Adviser's profitability in regard to the Fund and the Calvert Funds in the aggregate. In reviewing the overall profitability of the Fund to the Adviser, the Board also considered the fact that the Adviser and its affiliates provided sub-transfer agency support, administrative and distribution services to the Fund for which they received compensation. The information considered by the Board included the profitability of the Fund to the Adviser and its affiliates without regard to any marketing support or other payments by the Adviser and its affiliates to third parties in respect of distribution services. The Board also considered that the Adviser and its affiliates derived benefits to their reputation and other indirect benefits from their relationships with the Fund. Based upon its review, the Board concluded that the Adviser's and its affiliates' level of profitability from their relationships with the Fund was reasonable.

Economies of Scale

The Board considered the effect of the Fund's current size and its potential growth on its performance and fees. The Board concluded that adding breakpoints to the advisory fee at specified asset levels was not necessary at this time. The Board noted that if the Fund's assets increased over time, the Fund might realize other economies of scale if assets increased proportionally more than certain other expenses.

US Large-Cap Value Responsible Index Fund

Notes to Financial Statements

1 Significant Accounting Policies

Calvert US Large-Cap Value Responsible Index Fund (the Fund) is a diversified series of Calvert Responsible Index Series, 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 track the performance of the Calvert US Large-Cap Value Responsible Index, which measures the investment return of large-capitalization stocks.

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 0.25% 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.**

**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> None of the unobservable inputs for Level 3 assets, individually or collectively, had a material impact on the Fund. <br> <sup>(2)</sup> The level classification by major category of investments is the same as the category presentation in the Schedule of Investments.

Level 3 investments at the beginning and/or end of the period in relation to net assets were not significant and accordingly, a reconciliation of Level 3 assets for the year ended September 30, 2025 is not presented.

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. 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. 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.

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 Foreign Currency Translation— Other assets and liabilities initially expressed in foreign currencies are translated each business day into U.S. dollars based upon current exchange rates. Income and expenses denominated in foreign currencies are translated into U.S. dollars based upon currency exchange rates in effect on the respective dates of such transactions.

E 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.

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, 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.

H Federal Income 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.

I Segment Reporting— During this reporting period, the Fund adopted FASB Accounting Standards Update No. 2023-07, *Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures* (ASU 2023-07), which requires incremental disclosures related to a public entity's reportable segments. The Fund operates as a single reportable segment, an investment company whose investment objective(s) is included in Note 1. In connection with the adoption of ASU 2023-07, 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.

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 0.12% of the Fund's average daily net assets and is payable monthly. For the year ended September 30, 2025, the investment advisory fee amounted to $2,161,029.

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 year ended September 30, 2025, the investment advisory fee paid was reduced by $2,645 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 0.49%, 0.24% and 0.19% 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, 2026. For the year ended September 30, 2025, CRM waived and/or reimbursed expenses of $2,339,330.

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 year ended September 30, 2025, CRM was paid administrative fees of $2,161,029.

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 year ended September 30, 2025 amounted to $311,922 for Class A shares.

The Fund was informed that EVD received $15,691 as its portion of the sales charge on sales of Class A shares for the year ended September 30, 2025. The Fund was also informed that EVD received no contingent deferred sales charges paid by Class A shareholders 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 year ended September 30, 2025, sub-transfer agency fees and expenses incurred to EVM amounted to $34,224 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 $55,000 ($40,000 prior to January 1, 2025) annual fee, Committee chairs receive an additional $20,000 ($15,000 prior to January 1, 2025) 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.

During the year ended September 30, 2025, CRM reimbursed the Fund $221,085 for a net realized loss due to a trading error. The impact of the reimbursement was less than $0.01 per share for each class and had no significant impact on total return.

3 Investment Activity

During the year ended September 30, 2025, the cost of purchases and proceeds from sales of investments, other than short-term securities, were $482,803,061 and $631,264,267, respectively.

4 Distributions to Shareholders and Income Tax Information

The tax character of distributions declared for the years ended September 30, 2025 and September 30, 2024 was as follows:

---

| | | |
|:---|:---|:---|
|  | &nbsp;&nbsp;&nbsp;&nbsp;**Year Ended September 30,** | &nbsp;&nbsp;&nbsp;&nbsp;**Year Ended September 30,** |
|  | &nbsp;&nbsp;&nbsp;&nbsp;**2025** | &nbsp;&nbsp;&nbsp;&nbsp;**2024** |
| Ordinary income | &nbsp;&nbsp;&nbsp;&nbsp;$37808802 | &nbsp;&nbsp;&nbsp;&nbsp;$36264056 |
| Long-term capital gains | &nbsp;&nbsp;&nbsp;&nbsp;$67943688 | &nbsp;&nbsp;&nbsp;&nbsp;$— |

---

During the year ended September 30, 2025, distributable earnings was decreased by $14,408,091 and paid-in capital was increased by $14,408,091

due to the Fund's use of equalization accounting. Tax equalization accounting allows the Fund to treat as a distribution that portion of redemption proceeds representing a redeeming shareholder's portion of undistributed taxable income and net capital gains. These reclassifications had no effect on the net assets or net asset value per share of the Fund.

As of September 30, 2025, the components of distributable earnings (accumulated loss) on a tax basis were as follows:

---

| | |
|:---|:---|
| Undistributed ordinary income | &nbsp;&nbsp;&nbsp;&nbsp;$60038150 |
| Undistributed long-term capital gains | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;93516079 |
| Net unrealized appreciation | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;406194608 |
| **Distributable earnings** | &nbsp;&nbsp;&nbsp;&nbsp;**$559748837** |

---

The cost and unrealized appreciation (depreciation) of investments of the Fund at September 30, 2025, as determined on a federal income tax basis, were as follows:

---

| | |
|:---|:---|
| **Aggregate cost** | &nbsp;&nbsp;&nbsp;&nbsp;**$1483535094** |
| Gross unrealized appreciation | &nbsp;&nbsp;&nbsp;&nbsp;$473992726 |
| Gross unrealized depreciation | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(67798118) |
| **Net unrealized appreciation** | &nbsp;&nbsp;&nbsp;&nbsp;**$406194608** |

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 September 30, 2025, the total value of securities on loan was $9,021,500 and the total value of collateral received was $9,235,180, comprised of cash of $2,216,599 and U.S. government and/or agencies securities of $7,018,581.

The carrying amount of the liability for deposits for securities loaned at September 30, 2025 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 September 30, 2025.

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 21, 2025. 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 2024, 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 September 30, 2025. The Fund did not have any significant borrowings or allocated fees during the year ended September 30, 2025. Effective October 21, 2025, the Fund renewed its line of credit agreement, which expires October 20, 2026, at substantially the same terms

Report of Independent Registered Public Accounting Firm

------

To the Shareholders of Calvert US Large-Cap Value Responsible Index Fund and Board of Directors of Calvert Responsible Index Series, Inc.:

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Calvert US Large-Cap Value Responsible Index Fund (the "Fund"), one of the funds constituting Calvert Responsible Index Series, Inc., as of September 30, 2025, the related statement of operations for the year then ended, statements of changes in net assets for each of the two years in the period then ended, financial highlights for each of the five years in the period then ended, and the related notes (collectively referred to as the "financial statements and financial highlights"). In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of September 30, 2025, and the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on the Fund's financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. Our procedures included confirmation of securities owned as of September 30, 2025, by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

Board of Directors' Contract Approval

------

Overview of the Contract Review Process

The Investment Company Act of 1940, as amended, provides, in substance, that each investment advisory agreement between a fund and its investment adviser will continue in effect from year to year only if its continuation is approved at least annually by the fund's board of directors, including by a vote of a majority of the directors who are not "interested persons" of the fund ("Independent Directors"), cast in person at a meeting called for the purpose of considering such approval.

At an in-person meeting of the Boards of Trustees/Directors (each a "Board") of the registered investment companies advised by Calvert Research and Management ("CRM" or the "Adviser") (the "Calvert Funds") held on June 9-10, 2025, the Board, including a majority of the Independent Directors, voted to approve continuation of existing investment advisory and investment sub-advisory agreements for the Calvert Funds for an additional one-year period.

In evaluating the investment advisory and investment sub-advisory agreements for the Calvert Funds, the Board considered a variety of information relating to the Calvert Funds and various service providers, including the Adviser. The Independent Directors reviewed a report prepared by the Adviser regarding various services provided to the Calvert Funds by the Adviser and its affiliates. Such report included, among other data, information regarding the Adviser's personnel and the Adviser's revenue and cost of providing services to the Calvert Funds, and a separate report prepared by an independent data provider, which compared each fund's investment performance, fees and expenses to those of comparable funds as identified by such independent data provider ("comparable funds").

The Independent Directors were separately represented by independent legal counsel with respect to their consideration of the continuation of the investment advisory and investment sub-advisory agreements for the Calvert Funds. Prior to voting, the Independent Directors reviewed the proposed continuation of the Calvert Funds' investment advisory and investment sub-advisory agreements with management and also met in private sessions with their counsel at which time no representatives of management were present.

The information that the Board considered included, among other things, the following (for funds that invest through one or more affiliated underlying fund(s), references to "each fund" in this section may include information that was considered at the underlying fund-level):

*Information about Fees, Performance and Expenses*

• A report from an independent data provider comparing the advisory and related fees paid by each fund with fees paid by comparable funds;

• A report from an independent data provider comparing each fund's total expense ratio and its components to comparable funds;

• A report from an independent data provider comparing the investment performance of each fund to the investment performance of comparable funds over various time periods;

• Data regarding investment performance in comparison to benchmark indices;

• For each fund, comparative information concerning the fees charged and the services provided by the Adviser in managing other accounts (including mutual funds, other collective investment funds and institutional accounts) using investment strategies and techniques similar to those used in managing such fund;

• Profitability analyses for the Adviser with respect to each fund;

*Information about Portfolio Management and Trading*

• Descriptions of the investment management services provided to each fund, including investment strategies and processes it employs;

• Information about the Adviser's policies and practices with respect to trading, including the Adviser's processes for monitoring best execution of portfolio transactions;

• Information about the allocation of brokerage transactions and the benefits received by the Adviser as a result of brokerage allocation, including information concerning the acquisition of research through client commission arrangements and policies with respect to "soft dollars";

*Information about the Adviser*

• Reports detailing the financial results and condition of CRM;

• Descriptions of the qualifications, education and experience of the individual investment professionals whose responsibilities include portfolio management and investment research for the funds, and information relating to their compensation and responsibilities with respect to managing other mutual funds and investment accounts;

• Policies and procedures relating to proxy voting and the handling of corporate actions and class actions;

• A description of CRM's procedures for overseeing sub-advisers, including with respect to regulatory and compliance issues, investment management and other matters;

*Other Relevant Information*

• Information concerning the nature, cost and character of the administrative and other non-investment advisory services provided by CRM and its affiliates; and

• The terms of each investment advisory agreement.

Over the course of the year, the Board and its committees held regular quarterly meetings. During these meetings, the Directors participated in investment and performance reviews with the portfolio managers and other investment professionals of the Adviser relating to each fund and considered various investment and trading strategies used in pursuing each fund's investment objective(s), such as the use of derivative instruments, as well as risk management techniques. The Board and its committees also evaluated issues pertaining to industry and regulatory developments, compliance procedures, corporate governance and other issues with respect to the funds and received and participated in reports and presentations provided by CRM and its affiliates with respect to such matters. In addition to the formal meetings of the Board and its committees, the Independent Directors held regular video conferences in between meetings to discuss, among other topics, matters relating to the continuation of the Calvert Funds' investment advisory and investment sub-advisory agreements.

For funds that invest through one or more affiliated underlying funds, the Board considered similar information about the underlying fund(s) when considering the approval of investment advisory agreements. In addition, in cases where the Adviser has engaged a sub-adviser, the Board considered similar information about the sub-adviser when considering the approval of any investment sub-advisory agreement.

The Independent Directors were assisted throughout the contract review process by their independent legal counsel. The Independent Directors relied upon the advice of such counsel and their own business judgment in determining the material factors to be considered in evaluating each investment advisory and investment sub-advisory agreement and the weight to be given to each such factor. The Board, including the Independent Directors, did not identify any single factor as controlling, and each Director may have attributed different weight to various factors.

Results of the Contract Review Process

Based on its consideration of the foregoing, and such other information as it deemed relevant, including the factors and conclusions described below, the Board, including the Independent Directors, concluded that the continuation of the investment advisory agreement of Calvert US Large-Cap Value Responsible Index Fund (the "Fund"), including the fee payable under the agreement, is in the best interests of the Fund's shareholders. Accordingly, the Board, including a majority of the Independent Directors, voted to approve the continuation of the investment advisory agreement of the Fund.

Nature, Extent and Quality of Services

In considering the nature, extent and quality of the services provided by the Adviser under the investment advisory agreement, the Board reviewed information provided by the Adviser relating to its operations and personnel, including, among other information, biographical information on the Adviser's investment personnel and descriptions of its organizational and management structure. The Board also took into account similar information provided periodically throughout the previous year by the Adviser as well as the Board's familiarity with management through Board meetings, discussions and other reports. The Board considered the Adviser's management style and its performance in employing its investment strategies as well as its current level of staffing and overall resources. The Board also noted that it reviewed on a quarterly basis information regarding the Adviser's compliance with applicable policies and procedures, including those related to personal investing. The Board took into account, among other items, periodic reports received from the Adviser over the past year concerning the Adviser's ongoing review and enhancement of certain processes, policies and procedures of the Calvert Funds and the Adviser. The Board concluded that it was satisfied with the nature, extent and quality of services provided to the Fund by the Adviser under the investment advisory agreement.

Fund Performance

In considering the Fund's performance, the Board noted that it reviewed on a quarterly basis detailed information about the Fund's performance results, portfolio composition and investment strategies. The Board compared the Fund's investment performance to that of the Fund's peer universe and the index it is designed to track. The Board's review included comparative performance data for the one-, three- and five-year periods ended December 31, 2024. This performance data indicated that the Fund had underperformed the median of its peer universe for the one-, three- and five-year periods ended December 31, 2024. This performance data also indicated that the Fund had underperformed the index it is designed to track for the one-, three- and five-year periods ended December 31, 2024. The Board took into account management's discussion of the Fund's recent performance. Based upon its review, the Board concluded that the Fund's performance was satisfactory relative to the performance of its peer universe and the index it is designed to track.

Management Fees and Expenses

In considering the Fund's fees and expenses, the Board compared the Fund's fees and total expense ratio with those of comparable funds in its expense group. Among other findings, the data indicated that the Fund's advisory and administrative fees (after taking into account waivers and/or reimbursements) (referred to collectively as "management fees") and the Fund's total expenses (net of waivers and/or reimbursements) were each above the respective

median of the Fund's expense universe. The Board took into account the Adviser's current undertaking to maintain expense limitations for the Fund and that the Adviser had waived or reimbursed a portion of the Fund's expenses. Based upon its review, the Board concluded that the management fees were reasonable in view of the nature, extent and quality of services provided by the Adviser.

Profitability and Other "Fall-Out" Benefits

The Board reviewed the Adviser's profitability in regard to the Fund and the Calvert Funds in the aggregate. In reviewing the overall profitability of the Fund to the Adviser, the Board also considered the fact that the Adviser and its affiliates provided sub-transfer agency support, administrative and distribution services to the Fund for which they received compensation. The information considered by the Board included the profitability of the Fund to the Adviser and its affiliates without regard to any marketing support or other payments by the Adviser and its affiliates to third parties in respect of distribution services. The Board also considered that the Adviser and its affiliates derived benefits to their reputation and other indirect benefits from their relationships with the Fund. Based upon its review, the Board concluded that the Adviser's and its affiliates' level of profitability from their relationships with the Fund was reasonable.

Economies of Scale

The Board considered the effect of the Fund's current size and its potential growth on its performance and fees. The Board concluded that adding breakpoints to the advisory fee at specified asset levels was not necessary at this time. The Board noted that if the Fund's assets increased over time, the Fund might realize other economies of scale if assets increased proportionally more than certain other expenses.

Calvert

US Mid-Cap Core Responsible Index Fund

September 30, 2025

Notes to Financial Statements

------

1 Significant Accounting Policies

Calvert US Mid-Cap Core Responsible Index Fund (the Fund) is a diversified series of Calvert Responsible Index Series, 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 track the performance of the Calvert US Mid-Cap Core Responsible Index, which measures the investment return of mid-capitalization stocks.

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 0.25% 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.**

**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.

The following table summarizes the market value of the Fund's holdings as of September 30, 2025, based on the inputs used to value them:

<sup>(1)</sup> None of the unobservable inputs for Level 3 assets, individually or collectively, had a material impact on the Fund. <br> <sup>(2)</sup> The level classification by major category of investments is the same as the category presentation in the Schedule of Investments.

Level 3 assets at the beginning and/or end of the period in relation to net assets were not significant and accordingly, a reconciliation of Level 3 assets for the year ended September 30, 2025 is not presented.

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. 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 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.

E 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.

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, 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.

H Federal Income 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.

I Segment Reporting— During this reporting period, the Fund adopted FASB Accounting Standards Update No. 2023-07, *Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures* (ASU 2023-07), which requires incremental disclosures related to a public entity's reportable segments. The Fund operates as a single reportable segment, an investment company whose investment objective(s) is included in Note 1. In connection with the adoption of ASU 2023-07, 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.

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 0.12% of the Fund's average daily net assets and is payable monthly. For the year ended September 30, 2025, the investment advisory fee amounted to $547,904.

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 year ended September 30, 2025, the investment advisory fee paid was reduced by $705 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 0.49%, 0.24% and 0.20% 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, 2026. For the year ended September 30, 2025, CRM waived and/or reimbursed expenses of $712,710.

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 year ended September 30, 2025, CRM was paid administrative fees of $547,904.

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 year ended September 30, 2025 amounted to $166,190 for Class A shares.

The Fund was informed that EVD received $7,633 as its portion of the sales charge on sales of Class A shares and less than $100 of contingent deferred sales charges paid by Fund shareholders for the year ended September 30, 2025.

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 year ended September 30, 2025, sub-transfer agency fees and expenses incurred to EVM amounted to $42,488 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 $55,000 ($40,000 prior to January 1, 2025) annual fee, Committee chairs receive an additional $20,000 ($15,000 prior to January 1, 2025) 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.

During the year ended September 30, 2025, CRM reimbursed the Fund $79,392 for a net realized loss due to a trading error. The impact of the reimbursement was less than $0.01 per share for each class and had no significant impact on total return.

3 Investment Activity

During the year ended September 30, 2025, the cost of purchases and proceeds from sales of investments, other than short-term securities, were $125,172,532 and $178,317,855, respectively.

4 Distributions to Shareholders and Income Tax Information

The tax character of distributions declared for the years ended September 30, 2025 and September 30, 2024 was as follows:

---

| | | |
|:---|:---|:---|
|  | &nbsp;&nbsp;&nbsp;&nbsp;**Year Ended September 30,** | &nbsp;&nbsp;&nbsp;&nbsp;**Year Ended September 30,** |
|  | &nbsp;&nbsp;&nbsp;&nbsp;**2025** | &nbsp;&nbsp;&nbsp;&nbsp;**2024** |
| Ordinary income | &nbsp;&nbsp;&nbsp;&nbsp;$5040830 | &nbsp;&nbsp;&nbsp;&nbsp;$4541797 |

---

During the year ended September 30, 2025, distributable earnings was decreased by $1,872,788 and paid-in capital was increased by $1,872,788 due to the Fund's use of equalization accounting. Tax equalization accounting allows the Fund to treat as a distribution that portion of redemption proceeds representing a redeeming shareholder's portion of undistributed taxable income and net capital gains. These reclassifications had no effect on the net assets or net asset value per share of the Fund.

As of September 30, 2025, the components of distributable earnings (accumulated loss) on a tax basis were as follows:

---

| | |
|:---|:---|
| Undistributed ordinary income | &nbsp;&nbsp;&nbsp;&nbsp;$3922756 |
| Undistributed long-term capital gains | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;12827443 |
| Net unrealized appreciation | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;105034379 |
| **Distributable earnings** | &nbsp;&nbsp;&nbsp;&nbsp;**$121784578** |

---

The cost and unrealized appreciation (depreciation) of investments of the Fund at September 30, 2025, as determined on a federal income tax basis, were as follows:

---

| | |
|:---|:---|
| **Aggregate cost** | &nbsp;&nbsp;&nbsp;&nbsp;**$342615085** |
| Gross unrealized appreciation | &nbsp;&nbsp;&nbsp;&nbsp;$127046002 |
| Gross unrealized depreciation | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(22011623) |
| **Net unrealized appreciation** | &nbsp;&nbsp;&nbsp;&nbsp;**$105034379** |

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 September 30, 2025, the total value of securities on loan was $3,527,836 and the total value of collateral received was $3,605,116, comprised of cash of $605,087 and U.S. government and/or agencies securities of $3,000,029.

The carrying amount of the liability for deposits for securities loaned at September 30, 2025 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 September 30, 2025.

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 21, 2025. 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 2024, 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.

Report of Independent Registered Public Accounting Firm

------

To the Shareholders of Calvert US Mid-Cap Core Responsible Index Fund and Board of Directors of Calvert Responsible Index Series, Inc.:

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Calvert US Mid-Cap Core Responsible Index Fund (the "Fund"), one of the funds constituting Calvert Responsible Index Series, Inc., as of September 30, 2025, the related statement of operations for the year then ended, statements of changes in net assets for each of the two years in the period then ended, financial highlights for each of the five years in the period then ended, and the related notes (collectively referred to as the "financial statements and financial highlights"). In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of September 30, 2025, and the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on the Fund's financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. Our procedures included confirmation of securities owned as of September 30, 2025, by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

Board of Directors' Contract Approval

------

Overview of the Contract Review Process

The Investment Company Act of 1940, as amended, provides, in substance, that each investment advisory agreement between a fund and its investment adviser will continue in effect from year to year only if its continuation is approved at least annually by the fund's board of directors, including by a vote of a majority of the directors who are not "interested persons" of the fund ("Independent Directors"), cast in person at a meeting called for the purpose of considering such approval.

At an in-person meeting of the Boards of Trustees/Directors (each a "Board") of the registered investment companies advised by Calvert Research and Management ("CRM" or the "Adviser") (the "Calvert Funds") held on June 9-10, 2025, the Board, including a majority of the Independent Directors, voted to approve continuation of existing investment advisory and investment sub-advisory agreements for the Calvert Funds for an additional one-year period.

In evaluating the investment advisory and investment sub-advisory agreements for the Calvert Funds, the Board considered a variety of information relating to the Calvert Funds and various service providers, including the Adviser. The Independent Directors reviewed a report prepared by the Adviser regarding various services provided to the Calvert Funds by the Adviser and its affiliates. Such report included, among other data, information regarding the Adviser's personnel and the Adviser's revenue and cost of providing services to the Calvert Funds, and a separate report prepared by an independent data provider, which compared each fund's investment performance, fees and expenses to those of comparable funds as identified by such independent data provider ("comparable funds").

The Independent Directors were separately represented by independent legal counsel with respect to their consideration of the continuation of the investment advisory and investment sub-advisory agreements for the Calvert Funds. Prior to voting, the Independent Directors reviewed the proposed continuation of the Calvert Funds' investment advisory and investment sub-advisory agreements with management and also met in private sessions with their counsel at which time no representatives of management were present.

The information that the Board considered included, among other things, the following (for funds that invest through one or more affiliated underlying fund(s), references to "each fund" in this section may include information that was considered at the underlying fund-level):

*Information about Fees, Performance and Expenses*

• A report from an independent data provider comparing the advisory and related fees paid by each fund with fees paid by comparable funds;

• A report from an independent data provider comparing each fund's total expense ratio and its components to comparable funds;

• A report from an independent data provider comparing the investment performance of each fund to the investment performance of comparable funds over various time periods;

• Data regarding investment performance in comparison to benchmark indices;

• For each fund, comparative information concerning the fees charged and the services provided by the Adviser in managing other accounts (including mutual funds, other collective investment funds and institutional accounts) using investment strategies and techniques similar to those used in managing such fund;

• Profitability analyses for the Adviser with respect to each fund;

*Information about Portfolio Management and Trading*

• Descriptions of the investment management services provided to each fund, including investment strategies and processes it employs;

• Information about the Adviser's policies and practices with respect to trading, including the Adviser's processes for monitoring best execution of portfolio transactions;

• Information about the allocation of brokerage transactions and the benefits received by the Adviser as a result of brokerage allocation, including information concerning the acquisition of research through client commission arrangements and policies with respect to "soft dollars";

*Information about the Adviser*

• Reports detailing the financial results and condition of CRM;

• Descriptions of the qualifications, education and experience of the individual investment professionals whose responsibilities include portfolio management and investment research for the funds, and information relating to their compensation and responsibilities with respect to managing other mutual funds and investment accounts;

• Policies and procedures relating to proxy voting and the handling of corporate actions and class actions;

• A description of CRM's procedures for overseeing sub-advisers, including with respect to regulatory and compliance issues, investment management and other matters;

*Other Relevant Information*

• Information concerning the nature, cost and character of the administrative and other non-investment advisory services provided by CRM and its affiliates; and

• The terms of each investment advisory agreement.

Over the course of the year, the Board and its committees held regular quarterly meetings. During these meetings, the Directors participated in investment and performance reviews with the portfolio managers and other investment professionals of the Adviser relating to each fund and considered various investment and trading strategies used in pursuing each fund's investment objective(s), such as the use of derivative instruments, as well as risk management techniques. The Board and its committees also evaluated issues pertaining to industry and regulatory developments, compliance procedures, corporate governance and other issues with respect to the funds and received and participated in reports and presentations provided by CRM and its affiliates with respect to such matters. In addition to the formal meetings of the Board and its committees, the Independent Directors held regular video conferences in between meetings to discuss, among other topics, matters relating to the continuation of the Calvert Funds' investment advisory and investment sub-advisory agreements.

For funds that invest through one or more affiliated underlying funds, the Board considered similar information about the underlying fund(s) when considering the approval of investment advisory agreements. In addition, in cases where the Adviser has engaged a sub-adviser, the Board considered similar information about the sub-adviser when considering the approval of any investment sub-advisory agreement.

The Independent Directors were assisted throughout the contract review process by their independent legal counsel. The Independent Directors relied upon the advice of such counsel and their own business judgment in determining the material factors to be considered in evaluating each investment advisory and investment sub-advisory agreement and the weight to be given to each such factor. The Board, including the Independent Directors, did not identify any single factor as controlling, and each Director may have attributed different weight to various factors.

Results of the Contract Review Process

Based on its consideration of the foregoing, and such other information as it deemed relevant, including the factors and conclusions described below, the Board, including the Independent Directors, concluded that the continuation of the investment advisory agreement of Calvert US Mid-Cap Core Responsible Index Fund (the "Fund"), including the fee payable under the agreement, is in the best interests of the Fund's shareholders. Accordingly, the Board, including a majority of the Independent Directors, voted to approve the continuation of the investment advisory agreement of the Fund.

Nature, Extent and Quality of Services

In considering the nature, extent and quality of the services provided by the Adviser under the investment advisory agreement, the Board reviewed information provided by the Adviser relating to its operations and personnel, including, among other information, biographical information on the Adviser's investment personnel and descriptions of its organizational and management structure. The Board also took into account similar information provided periodically throughout the previous year by the Adviser as well as the Board's familiarity with management through Board meetings, discussions and other reports. The Board considered the Adviser's management style and its performance in employing its investment strategies as well as its current level of staffing and overall resources. The Board also noted that it reviewed on a quarterly basis information regarding the Adviser's compliance with applicable policies and procedures, including those related to personal investing. The Board took into account, among other items, periodic reports received from the Adviser over the past year concerning the Adviser's ongoing review and enhancement of certain processes, policies and procedures of the Calvert Funds and the Adviser. The Board concluded that it was satisfied with the nature, extent and quality of services provided to the Fund by the Adviser under the investment advisory agreement.

Fund Performance

In considering the Fund's performance, the Board noted that it reviewed on a quarterly basis detailed information about the Fund's performance results, portfolio composition and investment strategies. The Board compared the Fund's investment performance to that of the Fund's peer universe and the index it is designed to track. The Board's review included comparative performance data for the one-, three- and five-year periods ended December 31, 2024. This performance data indicated that the Fund had underperformed the median of its peer universe and the index it is designed to track for the one-, three and five-year periods ended December 31, 2024. The Board took into account management's discussion of the Fund's performance. Based upon its review, the Board concluded that the Fund's performance was satisfactory relative to the performance of its peer universe and the index it is designed to track.

Management Fees and Expenses

In considering the Fund's fees and expenses, the Board compared the Fund's fees and total expense ratio with those of comparable funds in its expense group. Among other findings, the data indicated that the Fund's advisory and administrative fees (after taking into account waivers and/or reimbursements) (referred to collectively as "management fees") were below the median of the Fund's expense group and the Fund's total expenses (net of waivers and/or reimbursements) were above the median of the Fund's expense group. The Board took into account the Adviser's current undertaking to maintain expense limitations for the Fund and that the Adviser had waived or reimbursed a portion of the Fund's expenses. Based upon its review, the Board concluded that the management fees were reasonable in view of the nature, extent and quality of services provided by the Adviser.

Profitability and Other "Fall-Out" Benefits

The Board reviewed the Adviser's profitability in regard to the Fund and the Calvert Funds in the aggregate. In reviewing the overall profitability of the Fund to the Adviser, the Board also considered the fact that the Adviser and its affiliates provided sub-transfer agency support, administrative and distribution services to the Fund for which they received compensation. The information considered by the Board included the profitability of the Fund to the Adviser and its affiliates without regard to any marketing support or other payments by the Adviser and its affiliates to third parties in respect of distribution services. The Board also considered that the Adviser and its affiliates derived benefits to their reputation and other indirect benefits from their relationships with the Fund. Based upon its review, the Board concluded that the Adviser's and its affiliates' level of profitability from their relationships with the Fund was reasonable.

Economies of Scale

The Board considered the effect of the Fund's current size and its potential growth on its performance and fees. The Board concluded that adding breakpoints to the advisory fee at specified asset levels was not necessary at this time. The Board noted that if the Fund's assets increased over time, the Fund might realize other economies of scale if assets increased proportionally more than certain other expenses.

Calvert

US Large-Cap Core Responsible Index Fund

1 Significant Accounting Policies

Calvert US Large-Cap Core Responsible Index Fund (the Fund) is a diversified series of Calvert Responsible Index Series, 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 track the performance of the Calvert US Large-Cap Core Responsible Index, which measures the investment return of large-capitalization stocks.

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 0.25% 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> None of the unobservable inputs for Level 3 assets, individually or collectively, had a material impact on the Fund. <br> <sup>(2)</sup> The level classification by major category of investments is the same as the category presentation in the Schedule of Investments.

Level 3 investments at the beginning and/or end of the period in relation to net assets were not significant and accordingly, a reconciliation of Level 3 assets for the year ended September 30, 2025 is not presented.

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. 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 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.

E 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.

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, 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.

H Federal Income 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.

I Segment Reporting— During this reporting period, the Fund adopted FASB Accounting Standards Update No. 2023-07, *Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures* (ASU 2023-07), which requires incremental disclosures related to a public entity's reportable segments. The Fund operates as a single reportable segment, an investment company whose investment objective(s) is included in Note 1. In connection with the adoption of ASU 2023-07, 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.

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 0.12% of the Fund's average daily net assets and is payable monthly. For the year ended September 30, 2025, the investment advisory fee amounted to $6,869,980.

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 year ended September 30, 2025, the investment advisory fee paid was reduced by $7,847 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 0.49%, 1.24%, 0.24% and 0.19% 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, 2026. For the year ended September 30, 2025, CRM waived and/or reimbursed expenses of $5,742,795.

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 year ended September 30, 2025, CRM was paid administrative fees of $6,869,980.

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 year ended September 30, 2025 amounted to $2,053,796 and $735,972 for Class A shares and Class C shares, respectively.

The Fund was informed that EVD received $65,608 as its portion of the sales charge on sales of Class A shares for the year ended September 30, 2025. The Fund was also informed that EVD received $3,131 of contingent deferred sales charges (CDSC) paid by Class C shareholders and no CDSC paid by Class A shareholders for the same period. The Fund was informed that Morgan Stanley affiliated broker-dealers, which may be deemed to be affiliates of CRM and EVD, also received a portion of the sales charge on sales of Class A shares for the year ended September 30, 2025 in the amount of $4,726.

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 year ended September 30, 2025, sub-transfer agency fees and expenses incurred to EVM amounted to $119,529 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 $55,000 ($40,000 prior to January 1, 2025) annual fee, Committee chairs receive an additional $20,000 ($15,000 prior to January 1, 2025) 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.

During the year ended September 30, 2025, CRM reimbursed the Fund $282,139 for a net realized loss due to a trading error. The impact of the reimbursement was less than $0.01 per share for each class and had no significant impact on total return.

3 Investment Activity

During the year ended September 30, 2025, the cost of purchases and proceeds from sales of investments, other than short-term securities, were $444,057,123 and $848,254,175, respectively.

4 Distributions to Shareholders and Income Tax Information

The tax character of distributions declared for the years ended September 30, 2025 and September 30, 2024 was as follows:

---

| | | |
|:---|:---|:---|
|  | &nbsp;&nbsp;&nbsp;&nbsp;**Year Ended September 30,** | &nbsp;&nbsp;&nbsp;&nbsp;**Year Ended September 30,** |
|  | &nbsp;&nbsp;&nbsp;&nbsp;**2025** | &nbsp;&nbsp;&nbsp;&nbsp;**2024** |
| Ordinary income | &nbsp;&nbsp;&nbsp;&nbsp;$52420052 | &nbsp;&nbsp;&nbsp;&nbsp;$47487507 |
| Long-term capital gains | &nbsp;&nbsp;&nbsp;&nbsp;$46494363 | &nbsp;&nbsp;&nbsp;&nbsp;$— |

---

During the year ended September 30, 2025, distributable earnings was decreased by $24,163,577 and paid-in capital was increased by $24,163,577

due to the Fund's use of equalization accounting. Tax equalization accounting allows the Fund to treat as a distribution that portion of redemption proceeds representing a redeeming shareholder's portion of undistributed taxable income and net capital gains. These reclassifications had no effect on the net assets or net asset value per share of the Fund.

As of September 30, 2025, the components of distributable earnings (accumulated loss) on a tax basis were as follows:

---

| | |
|:---|:---|
| Undistributed ordinary income | &nbsp;&nbsp;&nbsp;&nbsp;$38417172 |
| Undistributed long-term capital gains | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;224740129 |
| Net unrealized appreciation | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3473795498 |
| **Distributable earnings** | &nbsp;&nbsp;&nbsp;&nbsp;**$3736952799** |

---

The cost and unrealized appreciation (depreciation) of investments of the Fund at September 30, 2025, as determined on a federal income tax basis, were as follows:

---

| | |
|:---|:---|
| **Aggregate cost** | &nbsp;&nbsp;&nbsp;&nbsp;**$2561602336** |
| Gross unrealized appreciation | &nbsp;&nbsp;&nbsp;&nbsp;$3588135402 |
| Gross unrealized depreciation | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(114339904) |
| **Net unrealized appreciation** | &nbsp;&nbsp;&nbsp;&nbsp;**$3473795498** |

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 September 30, 2025, the total value of securities on loan was $19,673,216 and the total value of collateral received was $20,120,372, comprised of cash of $1,996,342 and U.S. government and/or agencies securities of $18,124,030.

The carrying amount of the liability for deposits for securities loaned at September 30, 2025 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 September 30, 2025.

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 21, 2025. 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 2024, 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 September 30, 2025. The Fund did not have any significant borrowings or allocated fees during the year ended September 30, 2025. Effective October 21, 2025, the Fund renewed its line of credit agreement, which expires October 20, 2026, at substantially the same terms.

7 Affiliated Investments

At September 30, 2025, the value of the Fund's investment in funds that may be deemed to be affiliated was $2,942,519, which represents 0.1% of the Fund's net assets. Transactions in such investments by the Fund for the year ended September 30, 2025 were as follows:

September 30, 2025

Report of Independent Registered Public Accounting Firm

------

To the Shareholders of Calvert US Large-Cap Core Responsible Index Fund and Board of Directors of Calvert Responsible Index Series, Inc.:

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Calvert US Large-Cap Core Responsible Index Fund (the "Fund"), one of the funds constituting Calvert Responsible Index Series, Inc., as of September 30, 2025, the related statement of operations for the year then ended, statements of changes in net assets for each of the two years in the period then ended, financial highlights for each of the five years in the period then ended, and the related notes (collectively referred to as the "financial statements and financial highlights"). In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of September 30, 2025, and the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on the Fund's financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. Our procedures included confirmation of securities owned as of September 30, 2025, by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

Board of Directors' Contract Approval

------

Overview of the Contract Review Process

The Investment Company Act of 1940, as amended, provides, in substance, that each investment advisory agreement between a fund and its investment adviser will continue in effect from year to year only if its continuation is approved at least annually by the fund's board of directors, including by a vote of a majority of the directors who are not "interested persons" of the fund ("Independent Directors"), cast in person at a meeting called for the purpose of considering such approval.

At an in-person meeting of the Boards of Trustees/Directors (each a "Board") of the registered investment companies advised by Calvert Research and Management ("CRM" or the "Adviser") (the "Calvert Funds") held on June 9-10, 2025, the Board, including a majority of the Independent Directors, voted to approve continuation of existing investment advisory and investment sub-advisory agreements for the Calvert Funds for an additional one-year period.

In evaluating the investment advisory and investment sub-advisory agreements for the Calvert Funds, the Board considered a variety of information relating to the Calvert Funds and various service providers, including the Adviser. The Independent Directors reviewed a report prepared by the Adviser regarding various services provided to the Calvert Funds by the Adviser and its affiliates. Such report included, among other data, information regarding the Adviser's personnel and the Adviser's revenue and cost of providing services to the Calvert Funds, and a separate report prepared by an independent data provider, which compared each fund's investment performance, fees and expenses to those of comparable funds as identified by such independent data provider ("comparable funds").

The Independent Directors were separately represented by independent legal counsel with respect to their consideration of the continuation of the investment advisory and investment sub-advisory agreements for the Calvert Funds. Prior to voting, the Independent Directors reviewed the proposed continuation of the Calvert Funds' investment advisory and investment sub-advisory agreements with management and also met in private sessions with their counsel at which time no representatives of management were present.

The information that the Board considered included, among other things, the following (for funds that invest through one or more affiliated underlying fund(s), references to "each fund" in this section may include information that was considered at the underlying fund-level):

*Information about Fees, Performance and Expenses*

• A report from an independent data provider comparing the advisory and related fees paid by each fund with fees paid by comparable funds;

• A report from an independent data provider comparing each fund's total expense ratio and its components to comparable funds;

• A report from an independent data provider comparing the investment performance of each fund to the investment performance of comparable funds over various time periods;

• Data regarding investment performance in comparison to benchmark indices;

• For each fund, comparative information concerning the fees charged and the services provided by the Adviser in managing other accounts (including mutual funds, other collective investment funds and institutional accounts) using investment strategies and techniques similar to those used in managing such fund;

• Profitability analyses for the Adviser with respect to each fund;

*Information about Portfolio Management and Trading*

• Descriptions of the investment management services provided to each fund, including investment strategies and processes it employs;

• Information about the Adviser's policies and practices with respect to trading, including the Adviser's processes for monitoring best execution of portfolio transactions;

• Information about the allocation of brokerage transactions and the benefits received by the Adviser as a result of brokerage allocation, including information concerning the acquisition of research through client commission arrangements and policies with respect to "soft dollars";

*Information about the Adviser*

• Reports detailing the financial results and condition of CRM;

• Descriptions of the qualifications, education and experience of the individual investment professionals whose responsibilities include portfolio management and investment research for the funds, and information relating to their compensation and responsibilities with respect to managing other mutual funds and investment accounts;

• Policies and procedures relating to proxy voting and the handling of corporate actions and class actions;

• A description of CRM's procedures for overseeing sub-advisers, including with respect to regulatory and compliance issues, investment management and other matters;

Board of Directors' Contract Approval — continued

------

*Other Relevant Information*

• Information concerning the nature, cost and character of the administrative and other non-investment advisory services provided by CRM and its affiliates; and

• The terms of each investment advisory agreement.

Over the course of the year, the Board and its committees held regular quarterly meetings. During these meetings, the Directors participated in investment and performance reviews with the portfolio managers and other investment professionals of the Adviser relating to each fund and considered various investment and trading strategies used in pursuing each fund's investment objective(s), such as the use of derivative instruments, as well as risk management techniques. The Board and its committees also evaluated issues pertaining to industry and regulatory developments, compliance procedures, corporate governance and other issues with respect to the funds and received and participated in reports and presentations provided by CRM and its affiliates with respect to such matters. In addition to the formal meetings of the Board and its committees, the Independent Directors held regular video conferences in between meetings to discuss, among other topics, matters relating to the continuation of the Calvert Funds' investment advisory and investment sub-advisory agreements.

For funds that invest through one or more affiliated underlying funds, the Board considered similar information about the underlying fund(s) when considering the approval of investment advisory agreements. In addition, in cases where the Adviser has engaged a sub-adviser, the Board considered similar information about the sub-adviser when considering the approval of any investment sub-advisory agreement.

The Independent Directors were assisted throughout the contract review process by their independent legal counsel. The Independent Directors relied upon the advice of such counsel and their own business judgment in determining the material factors to be considered in evaluating each investment advisory and investment sub-advisory agreement and the weight to be given to each such factor. The Board, including the Independent Directors, did not identify any single factor as controlling, and each Director may have attributed different weight to various factors.

Results of the Contract Review Process

Based on its consideration of the foregoing, and such other information as it deemed relevant, including the factors and conclusions described below, the Board, including the Independent Directors, concluded that the continuation of the investment advisory agreement of Calvert US Large-Cap Core Responsible Index Fund (the "Fund"), including the fee payable under the agreement, is in the best interests of the Fund's shareholders. Accordingly, the Board, including a majority of the Independent Directors, voted to approve the continuation of the investment advisory agreement of the Fund.

Nature, Extent and Quality of Services

In considering the nature, extent and quality of the services provided by the Adviser under the investment advisory agreement, the Board reviewed information provided by the Adviser relating to its operations and personnel, including, among other information, biographical information on the Adviser's investment personnel and descriptions of its organizational and management structure. The Board also took into account similar information provided periodically throughout the previous year by the Adviser as well as the Board's familiarity with management through Board meetings, discussions and other reports. The Board considered the Adviser's management style and its performance in employing its investment strategies as well as its current level of staffing and overall resources. The Board also noted that it reviewed on a quarterly basis information regarding the Adviser's compliance with applicable policies and procedures, including those related to personal investing. The Board took into account, among other items, periodic reports received from the Adviser over the past year concerning the Adviser's ongoing review and enhancement of certain processes, policies and procedures of the Calvert Funds and the Adviser. The Board concluded that it was satisfied with the nature, extent and quality of services provided to the Fund by the Adviser under the investment advisory agreement.

Fund Performance

In considering the Fund's performance, the Board noted that it reviewed on a quarterly basis detailed information about the Fund's performance results, portfolio composition and investment strategies. The Board compared the Fund's investment performance to that of the Fund's performance universe and the index it is designed to track. The Board's review included comparative performance data for the one-, three- and five-year periods ended December 31, 2024. This performance data indicated that the Fund had outperformed the median of its peer universe for the one- and five-year periods ended December 31, 2024, while it had underperformed the median of its peer universe for the three-year period ended December 31, 2024. This performance data also indicated that the Fund had underperformed the index it is designed to track for the one-, three- and five-year periods ended December 31, 2024. The Board took into account management's discussion of the Fund's performance. Based upon its review, the Board concluded that the Fund's performance was satisfactory relative to the performance of its peer universe and the index it is designed to track.

Management Fees and Expenses

In considering the Fund's fees and expenses, the Board compared the Fund's fees and total expense ratio with those of comparable funds in its expense group. Among other findings, the data indicated that the Fund's advisory and administrative fees (after taking into account waivers and/or reimbursements) (referred to collectively as "management fees") and the Fund's total expenses (net of waivers and/or reimbursements) were each above the respective median of the Fund's expense group. The Board took into account the Adviser's current undertaking to maintain expense limitations for the Fund and that the Adviser had waived or reimbursed a portion of the Fund's expenses. Based upon its review, the Board concluded that the management fees were reasonable in view of the nature, extent and quality of services provided by the Adviser.

Profitability and Other "Fall-Out" Benefits

The Board reviewed the Adviser's profitability in regard to the Fund and the Calvert Funds in the aggregate. In reviewing the overall profitability of the Fund to the Adviser, the Board also considered the fact that the Adviser and its affiliates provided sub-transfer agency support, administrative and distribution services to the Fund for which they received compensation. The information considered by the Board included the profitability of the Fund to the Adviser and its affiliates without regard to any marketing support or other payments by the Adviser and its affiliates to third parties in respect of distribution services. The Board also considered that the Adviser and its affiliates derived benefits to their reputation and other indirect benefits from their relationships with the Fund. Based upon its review, the Board concluded that the Adviser's and its affiliates' level of profitability from their relationships with the Fund was reasonable.

Economies of Scale

The Board considered the effect of the Fund's current size and its potential growth on its performance and fees. The Board concluded that adding breakpoints to the advisory fee at specified asset levels was not necessary at this time. The Board noted that if the Fund's assets increased over time, the Fund might realize other economies of scale if assets increased proportionally more than certain other expenses.
