Semiannual Report March 31, 2018 E-Delivery Sign-Up — Details Inside

Commodity Futures Trading Commission Registration. Effective December 31, 2012, the Commodity Futures Trading Commission (“CFTC”) adopted certain regulatory changes that subject registered investment companies and advisers to regulation by the CFTC if a fund invests more than a prescribed level of its assets in certain CFTC-regulated instruments (including futures, certain options and swap agreements) or markets itself as providing investment exposure to such instruments. The Fund and its adviser have claimed an exclusion from the definition of the term “commodity pool operator” under the Commodity Exchange Act. Accordingly, neither the Fund nor the adviser is subject to CFTC regulation.

Past performance is no guarantee of future results. Returns are historical and are calculated by determining the percentage change in net asset value (NAV) or offering price (as applicable) with all distributions reinvested. Investment return and principal value will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. Performance less than or equal to one year is cumulative. Performance is for the stated time period only; due to market volatility, the Fund's current performance may be lower or higher than quoted. Returns are before taxes unless otherwise noted. For performance as of the most recent month-end, please refer to www.calvert.com.

Endnotes and Additional Disclosures

MSCI EAFE Index is an unmanaged index of equities in the developed markets, excluding the U.S. and Canada. MSCI indexes are net of foreign withholding taxes. Source: MSCI. MSCI data may not be reproduced or used for any other purpose. MSCI provides no warranties, has not prepared or approved this report, and has no liability hereunder. Unless otherwise stated, index returns do not reflect the effect of any applicable sales charges, commissions, expenses, taxes or leverage, as applicable. It is not possible to invest directly in an index.

Total Returns at NAV do not include applicable sales charges. If sales charges were deducted, the returns would be lower. Total Returns shown with maximum sales charge reflect the stated maximum sales charge. Unless otherwise stated, performance does not reflect the deduction of taxes on Fund distributions or redemptions of Fund shares. Performance since inception for an index, if presented, is the performance since the Fund’s or oldest share class’ inception, as applicable.

Effective December 31, 2016, Calvert Research and Management (“CRM”) became the investment adviser to the Fund and performance reflected prior to such date is that of the Fund’s former investment adviser, Calvert Investment Management, Inc.

³Source: Fund prospectus. Net expense ratios reflect a contractual expense reimbursement that continues through 1/31/19. Without the reimbursement, performance would have been lower. The expense ratios for the current reporting period can be found in the Financial Highlights section of this report.

⁴Does not include Short Term Investment of Cash Collateral for Securities Loaned.

⁵ Excludes cash and cash equivalents.

FUND EXPENSES

Example

As a Fund shareholder, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchases and redemption fees (if applicable); and (2) ongoing costs, including management fees; distribution and/or service fees; and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of Fund investing and to compare these costs with the ongoing costs of investing in other mutual funds. The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (October 1, 2017 to March 31, 2018).

Actual Expenses

The first section of the table below provides information about actual account values and actual expenses. You may use the information in this section, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first section under the heading entitled “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second section of the table below provides information about hypothetical account values and hypothetical expenses based on the actual Fund expense ratio and an assumed rate of return of 5% per year (before expenses), which is not the actual Fund return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) or redemption fees (if applicable). Therefore, the second section of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would be higher.



	BEGINNING ACCOUNT VALUE (10/1/17)	ENDING ACCOUNT VALUE (3/31/18)	EXPENSES PAID DURING PERIOD* (10/1/17 - 3/31/18)	ANNUALIZED EXPENSE RATIO
Actual
Class A	$1,000.00	$1,043.80	$6.78**	1.33%
Class C	$1,000.00	$1,039.90	$10.58**	2.08%
Class I	$1,000.00	$1,045.40	$4.90**	0.96%
Hypothetical
(5% return per year before expenses)
Class A	$1,000.00	$1,018.30	$6.69**	1.33%
Class C	$1,000.00	$1,014.56	$10.45**	2.08%
Class I	$1,000.00	$1,020.15	$4.84**	0.96%

* Expenses are equal to the Fund's annualized expense ratio for the indicated Class, multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period). The Example assumes that the $1,000 was invested at the net asset value per share determined at the close of business on September 30, 2017.
** Absent a waiver and/or reimbursement of expenses by affiliates, expenses would be higher.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

NOTE 1 — SIGNIFICANT ACCOUNTING POLICIES

Calvert International Equity Fund (the Fund) is a diversified series of Calvert World Values Fund, Inc. (the Corporation). The Corporation is a Maryland corporation registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company. The investment objective of the Fund is to seek to provide a high total return consistent with reasonable risk by investing primarily in a diversified portfolio of stocks. The Fund invests primarily in equity securities of foreign companies.

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 0.80% may apply to certain redemptions of Class A shares for accounts for which no sales charge was paid, if redeemed within one year 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% on shares redeemed within one year of purchase. Class C shares are only available for purchase through a financial intermediary. Class I shares are sold at net asset value, are not subject to a sales charge and are sold only to certain eligible investors. The Fund previously offered Class Y shares. At the close of business on December 8, 2017, Class Y shares were converted to Class I shares. 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 under the direction of the Board.

The Board has adopted Valuation Procedures (the Procedures) to determine the fair value of securities and financial instruments for which market prices are not readily available or which may not be reliably priced. The Board has delegated the day-to-day responsibility for determining the fair value of securities and financial instruments of the Fund to Calvert Research and Management (CRM), the Fund's investment adviser and has provided these Procedures to govern CRM in its valuation duties.

CRM has chartered an internal Valuation Committee to oversee the implementation of these Procedures and to assist it in carrying out the valuation responsibilities that the Board has delegated. The Valuation Committee meets on a regular basis to review investments which may not have readily available market prices. The Valuation Committee’s fair valuation determinations are subject to review, approval and ratification by the Board at its next regularly scheduled meeting covering the calendar quarter in which the fair valuation was determined.

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.

Changes in valuation techniques may result in transfers in or out of an investment’s assigned level within the hierarchy during the period. Transfers in and/or out of levels are determined based on the fair value of such securities at the end of the period. 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 Global or Global Select Market 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 asked 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

www.calvert.com CALVERT INTERNATIONAL EQUITY FUND SEMIANNUAL REPORT (UNAUDITED) 17

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.

Debt Securities. Debt securities are generally valued on the basis of valuations provided by third party pricing services, as derived from such services’ pricing models. Inputs to the models may include, but are not limited to, reported trades, executable bid and asked prices, broker/dealer quotations, prices or yields of securities with similar characteristics, interest rates, anticipated prepayments, benchmark curves or information pertaining to the issuer, as well as industry and economic events. Accordingly, debt securities are generally categorized as Level 2 in the hierarchy. Short-term securities of sufficient credit quality purchased with remaining maturities of sixty days or less for which a valuation from a third party pricing service is not readily available may be valued at amortized cost, which approximates fair value, and are categorized as Level 2 in the hierarchy.

Venture Capital Securities. Venture capital securities for which market quotations are not readily available are generally categorized as Level 3 in the hierarchy. Venture capital equity securities are generally valued using the most appropriate and applicable method to measure fair value in light of each company’s situation. Methods may include market, income, options-pricing or cost approaches with discounts as appropriate based on assumptions of liquidation or exit risk. Examples of the market approach are subsequent rounds of financing, comparable transactions, and revenue times an industry multiple. An example of the income approach is the discounted cash flow model. Examples of the cost approach are replacement cost, salvage value, or net asset value. The options-pricing method treats common stock and preferred stock as call options on the enterprise value with strike price based on the preferred stock liquidation preference. Venture capital limited partnership interests are valued at the fair value reported by the general partner of the partnership, adjusted as necessary to reflect subsequent capital calls and distributions and any other available information. In some cases, adjustments may be made to account for daily pricing of material public holdings within the partnership.

Other Securities. Investments in registered investment companies (including money market funds) that do not trade on an exchange are valued at the net asset value per share on the valuation day and are categorized as Level 1 in the hierarchy.

Fair Valuation. If a market value cannot be determined for a security using the methodologies described above, or if, in the good faith opinion of the Fund's adviser, the market value does not constitute a readily available market quotation, or if a significant event has occurred that would materially affect the value of the security, the security will be fair valued as determined in good faith by or at the direction of the Board in a manner that fairly reflects the security’s value, or the amount that the Fund might reasonably expect to receive for the security upon its current sale in the ordinary course. Each such determination is based on a consideration of relevant factors, which are likely to vary from one pricing context to another. These factors may include, but are not limited to, the type of security, the existence of any contractual restrictions on the security’s disposition, the price and extent of public trading in similar securities of the issuer or of comparable 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 condition, 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 Valuation Committee employs various methods for calibrating these valuation approaches including a regular review of key inputs and assumptions, transactional back-testing or disposition analysis and reviews of any related market activity.

⁽¹⁾ None of the unobservable inputs for Level 3 assets, individually or collectively, had a material impact on the Fund.
⁽²⁾ For further breakdown of equity securities by country, please refer to the Schedule of Investments.
⁽³⁾ 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. In consideration of recent decisions rendered by European courts, the Fund has filed additional tax reclaims for previously withheld taxes on dividends earned in certain European Union countries. These filings are subject to various administrative and judicial proceedings within these countries. Due to the uncertainty as to the ultimate resolution of these proceedings, the likelihood of receipt of these reclaims, and the potential timing of payment, no amounts are reflected in the financial statements for such outstanding reclaims. 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, which includes amortization of premium and accretion of discount on debt securities, is accrued as earned.

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. 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.

www.calvert.com CALVERT INTERNATIONAL EQUITY FUND SEMIANNUAL REPORT (UNAUDITED) 19

F. Distributions to Shareholders: Distributions to shareholders are recorded by the Fund on ex-dividend date. Dividends from net investment income and distributions from net realized capital gains, if any, are paid at least annually. 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. Interim Financial Statements: The interim financial statements relating to March 31, 2018 and for the six months then ended have not been audited by an independent registered public accounting firm, but in the opinion of the Fund’s management, reflect all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of the financial statements.

NOTE 2 — RELATED PARTY TRANSACTIONS

The investment advisory fee is earned by CRM, a subsidiary of Eaton Vance Management (EVM), as compensation for investment advisory services rendered to the Fund. Pursuant to the investment advisory agreement, CRM receives a fee, payable monthly, at the following annual rates of the Fund’s average daily net assets: 0.75% on the first $250 million, 0.725% on the next $250 million and 0.675% on the excess of $500 million. For the six months ended March 31, 2018, the investment advisory fee amounted to $826,792 or 0.75% (annualized) of the Fund’s average daily net assets.

Eaton Vance Advisers International Ltd. (EVAIL), an indirect, wholly-owned subsidiary of Eaton Vance Corp., provides sub-advisory services to the Fund pursuant to a sub-advisory agreement with CRM. Sub-advisory fees are paid by CRM from its investment advisory fee. Prior to November 1, 2017, Eaton Vance Management (International) Limited (EVMI), an indirect, wholly-owned subsidiary of Eaton Vance Corp., served as sub-adviser to the Fund.

CRM and EVAIL (EVMI prior to November 1, 2017) have 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, interest expense, taxes or litigation expenses) exceed 1.32%, 2.07% and 0.95% for Class A, Class C and Class I, respectively, and prior to the close of business on December 8, 2017, 1.08% for Class Y, of such class’ average daily net assets. The expense reimbursement agreement may be changed or terminated after January 31, 2019. For the six months ended March 31, 2018, CRM, EVAIL and EVMI waived or reimbursed expenses of $196,659.

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 and Class I (and Class Y prior to the close of business on December 8, 2017) and is payable monthly. For the six months ended March 31, 2018, CRM was paid administrative fees of $132,198.

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 for distribution services and facilities provided to the Fund by EVD, as well as for personal services and/or the maintenance of shareholder accounts. The Fund also has in effect a distribution plan for Class C shares (Class C Plan) pursuant to Rule 12b-1 under the 1940 Act. Pursuant to the Class C Plan, the Fund pays EVD amounts equal to 0.75% per annum of its average daily net assets attributable to Class C shares for providing ongoing distribution services and facilities to the Fund. In addition, pursuant to the Class C Plan, the Fund also makes payments of service fees to EVD, financial intermediaries and other persons in amounts equal to 0.25% per annum of its average daily net assets attributable to that class. Service fees paid or accrued are for personal

services and/or the maintenance of shareholder accounts. Distribution and service fees paid or accrued for the six months ended March 31, 2018 amounted to $160,429 and $61,208 for Class A shares and Class C shares, respectively.

The Fund was informed that EVD received $10,039 as its portion of the sales charge on sales of Class A shares and $301 of contingent deferred sales charges paid by Fund shareholders for the six months ended March 31, 2018.

EVM provides sub-transfer agency and related services to the Fund pursuant to a Sub-Transfer Agency Support Services Agreement. For the six months ended March 31, 2018, sub-transfer agency fees and expenses incurred to EVM amounted to $34,913 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 a fee of $3,000 for each Board meeting attended in person and $2,000 for each Board meeting attended by phone plus an annual fee of $52,000, and $1,500 for each Committee meeting attended in person and $1,000 for each Committee meeting attended by phone plus an annual Committee fee of $2,500. The Board chair receives an additional $10,000 annual retainer and Committee chairs receive an additional $6,000 annual retainer. 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. In addition, an advisory council was established to aid the Board and CRM in advancing the cause of responsible investing through original scholarship and thought leadership. The advisory council consists of CRM’s Chief Executive Officer and four additional members. Each member (other than CRM’s Chief Executive Officer) receives annual compensation of $75,000, which is being reimbursed by Calvert Investment Management, Inc. (CIM), the Calvert funds’ former investment adviser and Ameritas Holding Company for a period of up to three years through December 30, 2019. For the six months ended March 31, 2018, the Fund’s allocated portion of such expense and reimbursement was $2,351, which are included in miscellaneous expense and reimbursement of expenses-other, respectively, on the Statement of Operations.

NOTE 3 — INVESTMENT ACTIVITY

During the six months ended March 31, 2018, the cost of purchases and proceeds from sales of investments, other than short-term securities, were $58,175,875 and $99,843,692, respectively.

NOTE 4 — DISTRIBUTIONS TO SHAREHOLDERS AND INCOME TAX INFORMATION

At September 30, 2017, the Fund, for federal income tax purposes, had capital loss carryforwards of $116,328,900 and deferred capital losses of $29,369,598 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 capital loss carryforwards will expire on September 30, 2018 ($105,942,268) and September 30, 2019 ($10,386,632) and their character is short-term. The deferred capital losses are treated as arising on the first day of the Fund’s next taxable year and retain the same short-term or long-term character as when originally deferred. Of the deferred capital losses at September 30, 2017, $11,471,284 are short-term and $17,898,314 are long-term.

Under tax regulations, capital losses incurred in taxable years beginning after December 22, 2010 can be carried forward to offset future capital gains for an unlimited period. These losses are required to be used prior to capital loss carryforwards, which carry an expiration date. As a result of this ordering rule, capital loss carryforwards may be more likely to expire unused.

The cost and unrealized appreciation (depreciation) of investments of the Fund at March 31, 2018, as determined on a federal income tax basis, were as follows:



Federal tax cost of investments		$189,824,796
Gross unrealized appreciation		$30,718,086
Gross unrealized depreciation	(4,955,849)
Net unrealized appreciation (depreciation)		$25,762,237

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 SSB. 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 on the basis of 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.

At March 31, 2018, the total value of securities on loan was $14,090,814 and the total value of collateral received was $14,542,476, comprised of cash of $12,444,856 and U.S. Government and/or agencies securities of $2,097,620.

The following table provides a breakdown of securities lending transactions accounted for as secured borrowings, the obligations by class of collateral pledged, and the remaining contractual maturity of those transactions as of March 31, 2018.

The carrying amount of the liability for deposits for securities loaned at March 31, 2018 approximated its fair value. If measured at fair value, such liability would have been considered as Level 2 in the fair value hierarchy (see Note 1A) at March 31, 2018.

NOTE 6 — LINE OF CREDIT

The Fund participates with other funds managed by CRM in a $50 million ($25 million committed and $25 million uncommitted) unsecured line of credit agreement with SSB, which is in effect through August 7, 2018. Borrowings may be made for temporary or emergency purposes only. Borrowings bear interest at the higher of the One-Month London Interbank Offered Rate (LIBOR) in effect that day or the overnight Federal Funds Rate, plus 1.25% per annum. A commitment fee of 0.25% per annum is incurred on the unused portion of the committed facility. An administrative fee of $30,000 was paid in connection with the renewal of the uncommitted facility. These fees are allocated to all participating 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 loans outstanding pursuant to this line of credit at March 31, 2018. The Fund did not have any significant borrowings or allocated fees during the six months ended March 31, 2018.

NOTE 7 — AFFILIATED COMPANIES

The Fund has invested a portion of its assets designated for high social impact investments in notes issued by Calvert Impact Capital, Inc. (CIC), formerly the Calvert Social Investment Foundation, pursuant to an exemptive order granted by the U.S. Securities and Exchange Commission (the SEC) in 1998 (the Exemptive Order). The Fund obtained the Exemptive Order because at that time there was a significant overlap of Fund Board members and CIC Board members as well as certain other affiliations between CIC and affiliates of the Fund’s investment adviser. CIC may be considered an affiliated person of the Fund based on the overlap between CIC’s Board of Directors and the Calvert funds’ Directors/Trustees and other potential affiliations. CIC has licensed use of the Calvert name from CRM, and currently two Fund Board members (one of whom is CRM’s President and Chief Executive Officer), two members of the Advisory Council to the Calvert Fund Board of Directors/Trustees, and an additional CRM officer serve on CIC’s Board. CIC is not owned or otherwise controlled by CRM or its affiliates. The Fund intends to request a new exemptive order from the SEC to permit additional investment in CIC notes.

In addition, an affiliated company is a company in which a fund has a direct or indirect ownership of, control of, or voting power of 5 percent or more of the outstanding voting shares, or a company that is under common ownership or control with a fund. At March 31, 2018, the value of the Fund’s investment in affiliated companies was $4,513,819, which represents 2.21% of the Fund’s net assets. Transactions in affiliated companies by the Fund for the six months ended March 31, 2018 were as follows:

NOTE 9 — RISKS ASSOCIATED WITH FOREIGN INVESTMENTS

Investing in foreign securities involves additional risks relating to political, social, and economic developments abroad. Other risks result from differences between regulations that apply to U.S. and foreign issuers and markets, and the potential for foreign markets to be less liquid and more volatile than U.S. markets. Securities that trade or are denominated in currencies other than the U.S. dollar may be adversely affected by fluctuations in currency exchange rates.

NOTE 10 — CAPITAL COMMITMENTS

In connection with certain venture capital and/or limited partnership investments, the Fund is committed to future capital calls, which will increase the Fund’s investment in these securities. The aggregate amount of the future capital commitments totaled $367,546 at March 31, 2018. The Fund had sufficient cash and/or securities to cover these commitments.

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 a 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 March 14, 2018, 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 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;

www.calvert.com CALVERT INTERNATIONAL EQUITY FUND SEMIANNUAL REPORT (UNAUDITED) 25


•	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 teleconferences 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 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 Equity Fund (the “Fund”), and the investment sub-advisory agreement with Eaton Vance Advisers International Ltd. (the “Sub-Adviser”), an affiliate of CRM, including the fees payable under each 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 and the investment sub-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 and Sub-Adviser under the investment advisory agreement and investment sub-advisory agreement, respectively, the Board reviewed information relating to the Adviser’s and Sub-Adviser’s operations and personnel, including, among other information, biographical information on the Sub-Adviser’s investment personnel and descriptions of the Adviser’s organizational and management structure. The Board also took into account similar information provided periodically throughout the previous year by the Adviser and Sub-Adviser as well as the Board’s familiarity with the Adviser and Sub-Adviser through Board meetings, discussions and other reports. With respect to the Adviser, the Board considered the Adviser’s responsibilities overseeing the Sub-Adviser and the business-related and other risks to which the Adviser or its affiliates may be subject in managing the Fund. With respect to the Sub-Adviser, the Board took into account the resources available to the Sub-Adviser in fulfilling its duties under the investment sub-advisory agreement and the Sub-Adviser’s experience in managing the Fund. The Board also noted that it reviewed on a quarterly basis information regarding the Adviser’s and Sub-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

26 www.calvert.com CALVERT INTERNATIONAL EQUITY FUND SEMIANNUAL REPORT (UNAUDITED)

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 and the Sub-Adviser under the investment advisory agreement and investment sub-advisory agreement, respectively.

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 appropriate Lipper benchmark index. The Board’s review included comparative performance data for the one-, three- and five-year periods ended September 30, 2017. This performance data indicated that the Fund had underperformed the median of its peer universe and its Lipper benchmark index for the one-, three- and five-year periods ended September 30, 2017. The Board took into account management’s discussion of the Fund’s performance and management’s continued monitoring 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 its Lipper benchmark index.

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 comparable funds and the Fund’s total expenses (net of waivers and/or reimbursements) were above the median of comparable funds. The Board took into account the Adviser’s current undertaking to maintain expense limitations for the Fund and that the Adviser was waiving and/or reimbursing a portion of the Fund’s expenses. Based upon its review, the Board concluded that the management and sub-advisory fees were reasonable in view of the nature, extent and quality of services provided by the Adviser and Sub-Adviser, respectively.

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, including the Sub-Adviser, provided sub-advisory, 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, including the Sub-Adviser, derived benefits to their reputation and other indirect benefits from their relationships with the Fund. Because the Adviser pays the Sub-Adviser’s sub-advisory fee out of its advisory fee, the profitability of the Fund to the Sub-Adviser was not a material factor in the Board’s deliberations concerning the continuation of the investment sub-advisory agreement. Based upon its review, the Board concluded that the level of profitability of the Adviser and its affiliates, including the Sub-Adviser, 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 also took into account the breakpoints in the advisory fee schedule for the Fund that would reduce the advisory fee rate on assets above specific asset levels. Because the Adviser pays the Sub-Adviser’s sub-advisory fee out of its advisory fee, the Board did not consider the potential economies of scale from the Sub-Adviser’s management of the Fund to be a material factor in the Board’s deliberations concerning the continuation of the investment sub-advisory agreement, although the Board noted that the sub-advisory fee schedule contained breakpoints. 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.

IMPORTANT NOTICES

Privacy. The Calvert Funds and Calvert Research and Management are committed to ensuring your financial privacy. Each of the financial institutions identified below has in effect the following policy (“Privacy Policy”) with respect to nonpublic personal information about its customers:


•	Only such information received from you, through application forms or otherwise, and information about your Calvert fund transactions will be collected. This may include information such as name, address, social security number, tax status, account balances and transactions.

•

None of such information about you (or former customers) will be disclosed to anyone, except as permitted by law (which includes disclosure to employees necessary to service your account). In the normal course of servicing a customer’s account, Calvert Research and Management may share information with unaffiliated third parties that perform various required services such as transfer agents, custodians and broker-dealers.


•	Policies and procedures (including physical, electronic and procedural safeguards) are in place that are designed to protect the confidentiality of such information.


•	The Funds reserve the right to change this Privacy Policy at any time upon proper notification to you. Customers may want to review the Funds’ Privacy Policy periodically for changes by accessing the link on our homepage: www.calvert.com.

Our pledge of privacy applies to the following entities: the Calvert Family of Funds, Calvert Research and Management and their affiliated service providers, Eaton Vance Management and Eaton Vance Distributors, Inc. In addition, our Privacy Policy applies only to those Calvert customers who are individuals and who have a direct relationship with us. If a customer’s account (i.e., fund shares) is held in the name of a third-party financial advisor/broker-dealer, it is likely that only such advisor’s privacy policies apply to the customer. This notice supersedes all previously issued privacy disclosures. For more information about Calvert’s Privacy Policy, please call 1-800-368-2745.

Delivery of Shareholder Documents. The Securities and Exchange Commission (SEC) permits funds to deliver only one copy of shareholder documents, including prospectuses, proxy statements and shareholder reports, to fund investors with multiple accounts at the same residential or post office box address. This practice is often called “householding” and it helps eliminate duplicate mailings to shareholders. Calvert funds, or your financial advisor, may household the mailing of your documents indefinitely unless you instruct Calvert funds, or your financial advisor, otherwise. If you would prefer that your Calvert fund documents not be householded, please contact Calvert funds at 1-800-368-2745, or contact your financial advisor. Your instructions that householding not apply to delivery of your Calvert fund documents will typically be effective within 30 days of receipt by Calvert funds or your financial advisor. Separate statements will be generated for each separate account and will be householded as described above.

Portfolio Holdings. Each Calvert fund will file a schedule of portfolio holdings on Form N-Q with the SEC for the first and third quarters of each fiscal year. The Form N-Q will be available on the Calvert funds’ website at www.calvert.com, by calling Calvert funds at 1-800-368-2745 or in the EDGAR database on the SEC’s website at www.sec.gov. Form N-Q may also be reviewed and copied at the SEC’s public reference room in Washington, D.C. (call 1-800-732-0330 for information on the operation of the public reference room).

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

NOTE 1 — SIGNIFICANT ACCOUNTING POLICIES

Calvert Mid-Cap Fund (the Fund) is a diversified series of Calvert World Values Fund, Inc. (the Corporation). The Corporation is a Maryland corporation registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company. The investment objective of the Fund is to seek to provide long-term capital appreciation by investing primarily in mid-cap stocks.

The Board has adopted Valuation Procedures (the Procedures) to determine the fair value of securities and financial instruments for which market prices are not readily available or which may not be reliably priced. The Board has delegated the day-to-day responsibility for determining the fair value of securities and financial instruments of the Fund to Calvert Research and Management (CRM), the Fund's investment adviser, and has provided these Procedures to govern CRM in its valuation duties.

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.

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.

The following table summarizes the market value of the Fund's holdings as of March 31, 2018, based on the inputs used to value them:



Assets	Level 1			Level 2		Level 3⁽¹⁾		Total
Common Stocks	$	240,760,879	⁽²⁾	$	—	$	—	$	240,760,879
High Social Impact Investments	—			2,487,387		671,299		3,158,686
Time Deposit	—			738,526		—		738,526
Short Term Investment of Cash Collateral for Securities Loaned	1,336,704			—		—		1,336,704
Total Investments	$	242,097,583		$	3,225,913	$	671,299	$	245,994,795

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

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 is included at the end of the Schedule of Investments.

NOTE 2 — RELATED PARTY TRANSACTIONS

The investment advisory fee is earned by CRM, a subsidiary of Eaton Vance Management (EVM), as compensation for investment advisory services rendered to the Fund. Pursuant to the investment advisory agreement, CRM receives a fee, payable monthly, at the annual rate of 0.65% of the Fund's average daily net assets. For the six months ended March 31, 2018, the investment advisory fee amounted to $823,515 of the Fund's average daily net assets.

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, interest expense, taxes or litigation expenses) exceed 1.21%, 1.96% and 0.86% for Class A, Class C and Class I, respectively, and prior to the close of business on December 8, 2017, 0.96% for Class Y, of such class’ average daily net assets. The expense reimbursement agreement with CRM may be changed or terminated after January 31, 2019. For the six months ended March 31, 2018, CRM waived or reimbursed expenses of $129,645.

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 and Class I (and Class Y prior to the close of business on December 8, 2017) and is payable monthly. CRM contractually waived 0.02% of the administrative fee through January 31, 2018 for Class I. For the six months ended March 31, 2018, CRM was paid administrative fees of $151,997, of which $4,910 were waived.

www.calvert.com CALVERT MID-CAP FUND SEMIANNUAL REPORT (UNAUDITED) 19

underwriter, a distribution and service fee of 0.25% per annum of its average daily net assets attributable to Class A for distribution services and facilities provided to the Fund by EVD, as well as for personal services and/or the maintenance of shareholder accounts. The Fund also has in effect a distribution plan for Class C shares (Class C Plan) pursuant to Rule 12b-1 under the 1940 Act. Pursuant to the Class C Plan, the Fund pays EVD amounts equal to 0.75% per annum of its average daily net assets attributable to Class C shares for providing ongoing distribution services and facilities to the Fund. In addition, pursuant to the Class C Plan, the Fund also makes payments of service fees to EVD, financial intermediaries and other persons in amounts equal to 0.25% per annum of its average daily net assets attributable to that class. Service fees paid or accrued are for personal services and/or the maintenance of shareholder accounts. Distribution and service fees paid or accrued for the six months ended March 31, 2018 amounted to $196,807 and $87,961 for Class A shares and Class C shares, respectively.

The Fund was informed that EVD received $8,741 and its portion of the sales charge on sales of Class A shares and $1,072 of contingent deferred sales charges paid by the Fund shareholders for the six months ended March 31, 2018.

EVM provides sub-transfer agency and related services to the Fund pursuant to a Sub-Transfer Agency Support Services Agreement. For the six months ended March 31, 2018, sub-transfer agency fees and expenses incurred to EVM amounted to $32,111 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 a fee of $3,000 for each Board meeting attended in person and $2,000 for each Board meeting attended by phone plus an annual fee of $52,000, and $1,500 for each Committee meeting attended in person and $1,000 for each Committee meeting attended by phone plus an annual Committee fee of $2,500. The Board chair receives an additional $10,000 annual retainer and Committee chairs receive an additional $6,000 annual retainer. 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. In addition, an advisory council was established to aid the Board and CRM in advancing the cause of responsible investing through original scholarship and thought leadership. The advisory council consists of CRM's Chief Executive Officer and four additional members. Each member (other than CRM's Chief Executive Officer) receives annual compensation of $75,000, which is being reimbursed by Calvert Investment Management, Inc. (CIM), the Calvert funds' former investment adviser, and Ameritas Holding Company for a period of up to three years through December 30, 2019. For the six months ended March 31, 2018, the Fund's allocated portion of such expense and reimbursement was $2,747, which are included in miscellaneous expense and reimbursement of expenses-other, respectively, on the Statement of Operations.

NOTE 3 — INVESTMENT ACTIVITY

During the six months ended March 31, 2018, the cost of purchases and proceeds from sales of investments, other than short-term securities, were $64,844,776 and $90,312,417, respectively.

NOTE 4 — DISTRIBUTIONS TO SHAREHOLDERS AND INCOME TAX INFORMATION

The cost and unrealized appreciation (depreciation) of investments of the Fund at March 31, 2018, as determined on a federal income tax basis, were as follows:



Federal tax cost of investments		$225,633,407
Gross unrealized appreciation		$29,128,472
Gross unrealized depreciation	(8,767,084)
Net unrealized appreciation (depreciation)		$20,361,388

NOTE 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 (SSB), the securities lending agent. Security loans are subject to termination by the Fund at any time and, therefore, are not considered to be illiquid investments. The Fund requires that the loan be continuously collateralized by either cash or securities as collateral equal at all times to at least 102% of the market value of the domestic securities loaned and 105% of the market value of the international securities loaned (if applicable). 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 SSB. 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 on the basis of agreed

20 www.calvert.com CALVERT MID-CAP FUND SEMIANNUAL REPORT (UNAUDITED)

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.

At March 31, 2018, the total value of securities on loan was $19,093,439 and the total value of collateral received was $19,315,618, comprised of cash of $1,336,704 and U.S. Government and/or agencies securities of $17,978,914.

NOTE 6 — LINE OF CREDIT

NOTE 7 — AFFILIATED COMPANIES

The Fund has invested a portion of its assets designated for high social impact investments in notes issued by Calvert Impact Capital, Inc. (CIC), formerly the Calvert Social Investment Foundation, pursuant to an exemptive order granted by the U.S. Securities and Exchange Commission (the SEC) in 1998 (the Exemptive Order). The Fund obtained the Exemptive Order because at that time there was a significant overlap of Fund Board members and CIC Board members as well as certain other affiliations between CIC and affiliates of the Fund’s investment adviser. CIC may be considered an affiliated person of the Fund based on the overlap between the CIC's Board of Directors and the Calvert funds’ Directors/Trustees and other potential affiliations. CIC has licensed use of the Calvert name from CRM, and currently two Fund Board members (one of whom is CRM’s President and Chief Executive Officer), two members of the Advisory Council to the Calvert Fund Board of Directors/Trustees, and an additional CRM officer serve on the CIC's Board. CIC is not owned or otherwise controlled by CRM or its affiliates. The Fund intends to request a new exemptive order from the SEC to permit additional investment in CIC notes.

In addition, an affiliated company is a company in which a fund has a direct or indirect ownership of, control of, or voting power of 5 percent or more of the outstanding voting shares, or a company that is under common ownership or control with a fund. At March 31, 2018, the value of the Fund's investment in affiliated companies was $2,487,387, which represents 1.0% of the Fund's net assets. Transactions in affiliated companies by the Fund for the six months ended March 31, 2018 were as follows:



Name of Affiliated Company	Principal Amount, beginning of period		Gross Additions		Gross Reductions		Principal Amount, end of period		Value, end of period		Interest Income		Net Realized Gain (Loss)		Capital Gain Distributions Received		Change in Unrealized Appreciation (Depreciation)

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 Mid-Cap 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 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.

Fund Performance

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 comparable funds and the Fund’s total expenses (net of waivers and/or reimbursements) were below the median of comparable funds. The Board took into account the Adviser’s current undertaking to maintain expense limitations for the Fund and that the Adviser was waiving and/or reimbursing 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.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

NOTE 1 — SIGNIFICANT ACCOUNTING POLICIES

Calvert International Opportunities Fund (the Fund) is a diversified series of Calvert World Values Fund, Inc. (the Corporation). The Corporation is a Maryland corporation registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company. The investment objective of the Fund is to seek long-term capital appreciation. The Fund invests primarily in common and preferred stocks of non-U.S. small-cap to mid-cap companies.

The Fund offers three classes of shares. Class A shares are generally sold subject to a sales charge imposed at the time of purchase. A contingent deferred sales charge of 0.80% may apply to certain redemptions of Class A shares for accounts for which no sales charge was paid, if redeemed within one year 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% on shares redeemed within one year of purchase. Class C shares are only available for purchase through a financial intermediary. Class I shares are sold at net asset value, are not subject to a sales charge and are sold only to certain eligible investors. The Fund previously offered Class Y shares. At the close of business on December 8, 2017, Class Y shares were converted to Class I shares. Each class represents a pro rata interest in the Fund, but votes separately on class-specific matters and is subject to different expenses.

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.

www.calvert.com CALVERT INTERNATIONAL OPPORTUNITIES FUND SEMIANNUAL REPORT (UNAUDITED) 17

Other Securities. Exchange-traded funds are valued at the official 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. Investments in registered investment companies (including money market funds) that do not trade on an exchange are valued at the net asset value per share on the valuation day and are categorized as Level 1 in the hierarchy.

The following table summarizes the market value of the Fund's holdings as of March 31, 2018, based on the inputs used to value them:



Assets	Level 1		Level 2			Level 3⁽¹⁾		Total

⁽¹⁾ None of the unobservable inputs for Level 3 assets, individually or collectively, had a material impact on the Fund.

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 six months ended March 31, 2018 is not presented. At March 31, 2018, investments having a value of $18,263,261 were transferred from Level 1 to Level 2 during the six months then ended. The change in level designation within the fair value hierarchy was generally due to an increase in securities valued primarily using the Fund’s fair valuation pricing service.

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

NOTE 2 — RELATED PARTY TRANSACTIONS

The investment advisory fee is earned by CRM, a subsidiary of Eaton Vance Management (EVM), as compensation for investment advisory services rendered to the Fund. Pursuant to the investment advisory agreement, CRM receives a fee, payable monthly, at the annual rate of 0.75% of the Fund’s average daily net assets. For the six months ended March 31, 2018, the investment advisory fee amounted to $877,273.

CRM and EVAIL (EVMI prior to November 1, 2017) have 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, interest expense, taxes or litigation expenses) exceed 1.43%, 2.26% and 1.16% for Class A, Class C and Class I, respectively, and prior to the close of business on December 8, 2017, 1.41% for Class Y, of such class’ average daily net assets. The expense reimbursement agreement may be changed or terminated after January 31, 2019. For the six months ended March 31, 2018, CRM, EVAIL and EVMI waived or reimbursed no expenses.

The Fund was informed that EVD received $17,093 as its portion of the sales charge on sales of Class A shares and $329 of contingent deferred sales charges paid by Fund shareholders for the six months ended March 31, 2018.

EVM provides sub-transfer agency and related services to the Fund pursuant to a Sub-Transfer Agency Support Services Agreement. For the six months ended March 31, 2018, sub-transfer agency fees and expenses incurred to EVM amounted to $15,857 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 a fee of $3,000 for each Board meeting attended in person and $2,000 for each Board meeting attended by phone plus an annual fee of $52,000, and $1,500 for each Committee meeting attended in person and $1,000 for each Committee meeting attended by phone plus an annual Committee fee of $2,500. The Board chair receives an additional $10,000 annual retainer and Committee chairs receive an additional $6,000 annual retainer. 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. In addition, an advisory council was established to aid the Board and CRM in advancing the cause of responsible investing through original scholarship and thought leadership. The advisory council consists of CRM's Chief Executive Officer and four additional members. Each member (other than CRM's Chief Executive Officer) receives annual compensation of $75,000, which is being reimbursed by Calvert Investment Management, Inc. (CIM), the Calvert funds’ former investment adviser and Ameritas Holding Company for a period of up to three years through December 30, 2019. For the six months ended March 31, 2018, the Fund’s allocated portion of such expense and reimbursement was $2,450, which are included in miscellaneous expense and reimbursement of expenses-other, respectively, on the Statement of Operations.

The Fund had no loans outstanding pursuant to this line of credit at March 31, 2018. The Fund did not have any significant borrowings or allocated fees during the six months ended March 31, 2018.

NOTE 7 — AFFILIATED COMPANIES

The Fund has invested a portion of its assets designated for high social impact investments in notes issued by Calvert Impact Capital, Inc. (CIC), formerly the Calvert Social Investment Foundation, pursuant to an exemptive order granted by the U.S. Securities and Exchange Commission (the SEC) in 1998 (the Exemptive Order). The Fund obtained the Exemptive Order because at that time there was a significant overlap of Fund Board members and CIC Board members as well as certain other affiliations between CIC and affiliates of the Fund’s investment adviser. CIC may be considered an affiliated person of the Fund based on the overlap between CIC's Board of Directors and the Calvert funds’ Directors/Trustees and other potential affiliations. CIC has licensed use of the Calvert name from CRM, and currently two Fund Board members (one of whom is CRM’s President and Chief Executive Officer), two members of the Advisory Council to the Calvert Fund Board of Directors/Trustees, and an additional CRM officer serve on CIC's Board. CIC is not owned or otherwise controlled by CRM or its affiliates. The Fund intends to request a new exemptive order from the SEC to permit additional investment in CIC notes.

In addition, an affiliated company is a company in which a fund has a direct or indirect ownership of, control of, or voting power of 5 percent or more of the outstanding voting shares, or a company that is under common ownership or control with a fund. At March 31, 2018, the value of the Fund's investment in affiliated companies was $949,570, which represents 0.37% of the Fund's net assets. Transactions in affiliated companies by the Fund for the six months ended March 31, 2018 were as follows:



Name of Affiliated Company	Principal Amount, beginning of period		Gross Additions		Gross Reductions		Principal Amount, end of period		Value, end of period		Interest Income		Net Realized Gain (Loss)		Capital Gain Distributions Received		Change in Unrealized Appreciation (Depreciation)

NOTE 9 — RISKS ASSOCIATED WITH FOREIGN INVESTMENTS

The risks of investing in emerging market securities are greater than those of investing in securities of developed foreign countries. These risks include volatile currency exchange rates, periods of high inflation, increased risk of default, greater social, economic and political uncertainty and instability, less governmental supervision and regulation of securities markets, weaker auditing and financial reporting standards, lack of liquidity in the markets, and the significantly smaller market capitalization of emerging market issuers.

Information about the Adviser


•	Reports detailing the financial results and condition of CRM;

24 www.calvert.com CALVERT INTERNATIONAL OPPORTUNITIES FUND SEMIANNUAL REPORT (UNAUDITED)


•	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;

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.

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 Opportunities Fund (the “Fund”), and the investment sub-advisory agreement with Eaton Vance Advisers International Ltd. (the “Sub-Adviser”), an affiliate of CRM, including the fees payable under each 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 and the investment sub-advisory agreement of the Fund.

Nature, Extent and Quality of Services

www.calvert.com CALVERT INTERNATIONAL OPPORTUNITIES FUND SEMIANNUAL REPORT (UNAUDITED) 25

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 appropriate Lipper benchmark index. The Board’s review included comparative performance data for the one-, three- and five-year periods ended September 30, 2017. This performance data indicated that the Fund had outperformed the median of peer universe funds for the one-and five year periods ended September 30, 2017, equaled the median of peer universe funds for the three-year period, outperformed its Lipper benchmark index for the one- and five-year periods ended September 30, 2017, and underperformed its Lipper benchmark index for the three-year period ended September 30, 2017. Based upon its review, the Board concluded that the Fund’s performance was satisfactory relative to the performance of its peer universe and its Lipper benchmark index.

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 at the median of comparable funds and the Fund’s total expenses (net of waivers and/or reimbursements) were below the median of comparable funds. The Board took into account the Adviser’s current undertaking to maintain expense limitations for the Fund and that the Adviser was waiving and/or reimbursing a portion of the Fund’s expenses. Based upon its review, the Board concluded that the management and sub-advisory fees were reasonable in view of the nature, extent and quality of services provided by the Adviser and Sub-Adviser, respectively.

Profitability and Other “Fall-Out” Benefits

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 specific asset levels would not be appropriate at this time given the Fund’s current size. Because the Adviser pays the Sub-Adviser’s sub-advisory fee out of its advisory fee, the Board did not consider the potential economies of scale from the Sub-Adviser’s management of the Fund to be a material factor in the Board’s deliberations concerning the continuation of the investment sub-advisory agreement. 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.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

NOTE 1 — SIGNIFICANT ACCOUNTING POLICIES

Calvert Emerging Markets Equity Fund (the Fund) is a diversified series of Calvert World Values Fund, Inc. (the Corporation). The Corporation is a Maryland corporation registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company. The investment objective of the Fund is to seek long-term capital appreciation by investing primarily in equity securities of companies located in emerging market countries.

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 0.80% may apply to certain redemptions of Class A shares for accounts for which no sales charge was paid, if redeemed within one year 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% on shares redeemed within one year of purchase. Class C shares are only available for purchase through a financial intermediary. 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. The Fund previously offered Class Y shares. At the close of business on December 8, 2017, Class Y shares were converted to Class I shares. Each class represents a pro rata interest in the Fund, but votes separately on class-specific matters and is subject to different expenses.

The Board has adopted Valuation Procedures (the Procedures) to determine the fair value of securities and financial instruments for which market prices are not readily available or which may not be reliably priced. The Board has delegated the day-to-day responsibility for determining the fair value of securities and financial instruments of the Fund to Calvert Research and Management (CRM), the Fund's investment adviser, and has provided these Procedures to govern CRM in its valuation duties.

⁽¹⁾ None of the unobservable inputs for Level 3 assets, individually or collectively, had a material impact on the Fund.
⁽²⁾For further breakdown of equity securities by country, please refer to the Schedule of Investments.
⁽³⁾ 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.

At March 31, 2018, investments having a value of $10,478,925 were transferred from Level 1 to Level 2 during the six months then ended. The change in level designation within the fair value hierarchy was generally due to an increase in securities valued primarily using the Fund's fair valuation pricing service.

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 and dividend disbursing agent fees on the Statement of Operations, are not allocated to Class R6 shares.

E. Participatory Notes: The Fund may gain exposure to securities in certain foreign markets through investments in participatory notes (P-notes), especially in markets where direct investment by the Fund is not possible. P-notes are generally issued by a bank or broker-dealer (the counterparty) and are designed to offer a return linked to a particular underlying equity security. While the holder of a P-note is entitled to receive from the counterparty any dividends paid by the underlying security, the counterparty

www.calvert.com CALVERT EMERGING MARKETS EQUITY FUND SEMIANNUAL REPORT (UNAUDITED) 19

retains legal ownership and voting rights of the underlying security. The risks associated with investing in a P-note may include the possible failure of the counterparty to perform its obligations under the terms of the agreement, an inability to liquidate or transfer the notes, and an imperfect correlation between the value of the P-note and the underlying security.

F. 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.

G. Distributions to Shareholders: Distributions to shareholders are recorded by the Fund on ex-dividend date. Dividends from net investment income and distributions from net realized capital gains, if any, are paid at least annually. 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.

H. 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.

I. 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.

J. 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.

K. Interim Financial Statements: The interim financial statements relating to March 31, 2018 and for the six months then ended have not been audited by an independent registered public accounting firm, but in the opinion of the Fund’s management, reflect all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of the financial statements.

NOTE 2 — RELATED PARTY TRANSACTIONS

The investment advisory fee is earned by CRM, a subsidiary of Eaton Vance Management (EVM), as compensation for investment advisory services rendered to the Fund. Pursuant to the investment advisory agreement, CRM receives a fee, payable monthly, at the annual rate of 0.88% of the Fund’s average daily net assets. For the six months ended March 31, 2018, the investment advisory fee amounted to $2,531,120 or 0.88% (annualized) of the Fund's average daily net assets.

Hermes Investment Management Limited (Hermes) provides sub-advisory services to the Fund pursuant to a sub-advisory agreement with CRM. Sub-advisory fees are paid by CRM from its investment advisory fee.

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, interest expense, taxes or litigation expenses) exceed 1.27%, 2.02%, 0.92% and 0.92% for Class A, Class C, Class I and Class R6, respectively, and prior to the close of business on December 8, 2017, 0.85% for Class Y, of such class’ average daily net assets. The expense reimbursement agreement may be changed or terminated after January 31, 2019. For the six months ended March 31, 2018, CRM waived or reimbursed expenses of $864,031. A portion of the expenses waived or reimbursed was borne by Hermes.

20 www.calvert.com CALVERT EMERGING MARKETS EQUITY FUND SEMIANNUAL REPORT (UNAUDITED)

administrative fee through January 31, 2018 for Class I. For the six months ended March 31, 2018, CRM was paid administrative fees of $344,545, of which $18,144 were waived.

The Fund was informed that EVD received $54,025 as its portion of the sales charge on sales of Class A shares and $1,099 of contingent deferred sales charges paid by Fund shareholders for the six months ended March 31, 2018.

EVM provides sub-transfer agency and related services to the Fund pursuant to a Sub-Transfer Agency Support Services Agreement. For the six months ended March 31, 2018, sub-transfer agency fees and expenses incurred to EVM amounted to $24,417 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 a fee of $3,000 for each Board meeting attended in person and $2,000 for each Board meeting attended by phone plus an annual fee of $52,000, and $1,500 for each Committee meeting attended in person and $1,000 for each Committee meeting attended by phone plus an annual Committee fee of $2,500. The Board chair receives an additional $10,000 annual retainer and Committee chairs receive an additional $6,000 annual retainer. 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. In addition, an advisory council was established to aid the Board and CRM in advancing the cause of responsible investing through original scholarship and thought leadership. The advisory council consists of CRM’s Chief Executive Officer and four additional members. Each member (other than CRM’s Chief Executive Officer) receives annual compensation of $75,000, which is being reimbursed by Calvert Investment Management, Inc. (CIM), the Calvert funds’ former investment adviser, and Ameritas Holding Company for a period of up to three years through December 30, 2019. For the six months ended March 31, 2018, the Fund’s allocated portion of such expense and reimbursement was $5,038, which are included in miscellaneous expense and reimbursement of expenses-other, respectively, on the Statement of Operations.

NOTE 3 — INVESTMENT ACTIVITY

During the six months ended March 31, 2018, the cost of purchases and proceeds from sales of investments, other than short-term securities, were $683,034,125 and $88,768,871, respectively.

NOTE 4 — DISTRIBUTIONS TO SHAREHOLDERS AND INCOME TAX INFORMATION

At September 30, 2017, the Fund, for federal income tax purposes, had deferred capital losses of $1,559,277 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 and retain the same short-term or long-term character as when originally deferred. Of the deferred capital losses at September 30, 2017, $1,559,277 are long-term.

The cost and unrealized appreciation (depreciation) of investments of the Fund at March 31, 2018, as determined on a federal income tax basis, were as follows:



Federal tax cost of investments		$845,774,104
Gross unrealized appreciation		$89,365,292
Gross unrealized depreciation	(10,621,871)
Net unrealized appreciation (depreciation)		$78,743,421

NOTE 6 — LINE OF CREDIT

NOTE 7 — AFFILIATED COMPANIES

The Fund has invested a portion of its assets designated for high social impact investments in notes issued by Calvert Impact Capital, Inc. (CIC), formerly the Calvert Social Investment Foundation, pursuant to an exemptive order granted by the U.S. Securities and Exchange Commission (the SEC) in 1998 (the Exemptive Order). The Fund obtained the Exemptive Order because at that time there was a significant overlap of Fund Board members and CIC Board members as well as certain other affiliations between CIC and affiliates of the Fund’s investment adviser. CIC may be considered an affiliated person of the Fund based on the overlap between CIC's Board of Directors and the Calvert funds’ Directors/Trustees and other potential affiliations. CIC has licensed use of the Calvert name from CRM, and currently two Fund Board members (one of whom is CRM’s President and Chief Executive Officer), two members of the Advisory Council to the Calvert Fund Board of Directors/Trustees, and an additional CRM officer serve on CIC's Board. CIC is not owned or otherwise controlled by CRM or its affiliates. The Fund intends to request a new exemptive order from the SEC to permit additional investment in CIC notes.

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 Emerging Markets Equity Fund (the “Fund”), and the investment sub-advisory agreement with Hermes Investment Management Limited (the “Sub-Adviser”), including the fees payable under each 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 and the investment sub-advisory agreement of the Fund.

Nature, Extent and Quality of Services

26 www.calvert.com CALVERT EMERGING MARKETS EQUITY FUND SEMIANNUAL REPORT (UNAUDITED)

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 appropriate Lipper benchmark index. The Board’s review included comparative performance data for the one- and three-year periods ended September 30, 2017. This performance data indicated that the Fund had outperformed the median of its peer universe and its Lipper benchmark index for the one- and three-year periods ended September 30, 2017. Based upon its review, the Board concluded that the Fund’s performance was satisfactory relative to the performance of its peer universe and its Lipper benchmark index.

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 comparable funds and the Fund’s total expenses (net of waivers and/or reimbursements) were below the median of comparable funds. The Board took into account the Adviser’s current undertaking to maintain expense limitations for the Fund and that the Adviser was waiving and/or reimbursing a portion of the Fund’s expenses. Based upon its review, the Board concluded that the management and sub-advisory fees were reasonable in view of the nature, extent and quality of services provided by the Adviser and Sub-Adviser, respectively.

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. Because the Adviser pays the Sub-Adviser’s sub-advisory fee out of its advisory fee and the sub-advisory fee was negotiated at arm’s length by the Adviser, the profitability of the Fund to the Sub-Adviser was not a material factor in the Board’s deliberations concerning the continuation of the investment sub-advisory agreement. Based upon its review, the Board concluded that the level of profitability of the Adviser and its affiliates 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 specific asset levels would not be appropriate at this time given the Fund’s current size. Because the Adviser pays the Sub-Adviser’s sub-advisory fee out of its advisory fee and the sub-advisory fee was negotiated at arm’s length by the Adviser, the Board did not consider the potential economies of scale from the Sub-Adviser’s management of the Fund to be a material factor in the Board’s deliberations concerning the continuation of the investment sub-advisory agreement. 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.
