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.

MANAGEMENT’S DISCUSSION OF FUND PERFORMANCE¹ 

Economic and Market Conditions

Led by higher U.S. stocks, most global stock indexes advanced during the 12-month period ended September 30, 2018.

U.S. stocks opened the period on the upswing as investors anticipated, and then cheered passage of the Republican tax reform package in December 2017. Sharp cuts in corporate taxes - a key element of the bill - raised corporate-profit expectations. Stocks also got a boost from positive U.S. economic data, including the unemployment rate, which fell to a 17-year low.

Early in the period, global stocks followed U.S. stocks sharply higher. European stocks got a boost from growing economies and rising corporate profits across the region. Key equity indexes in the Asia-Pacific region also rose despite tensions with North Korea. China’s stock market advanced behind an accelerating housing market, rising retail sales, and strong foreign trade.

U.S. stocks pulled back in February 2018 amid fears that rising rates would spur inflation and boost the appeal of fixed-income investments at the expense of stocks. After a brief rebound, equity markets weakened in the spring of 2018, as investors confronted the prospect of a global trade war due to President Trump’s imposition of broad new tariffs. The protectionist move drew retaliatory action from impacted countries including China, Canada, and certain countries in the European Union.

European stocks also pulled back even more substantially amid mounting trade war concerns, before a partial recovery in the final months of the period. In China, signs of a slowing economy compounded trade war concerns, sending Chinese stocks into a prolonged slump that reached bear market territory in late June 2018.

U.S. stocks bounced back strongly in the final three months of the period. Technology stocks led the advance, overcoming an earlier setback from a wave of data-privacy scandals. U.S. economic indicators remained largely positive throughout the period, prompting the U.S. Federal Reserve to raise its benchmark interest rate three times over the 12-month span.

For the 12-month period ended September 30, 2018, the MSCI World Index,² a proxy for global equities, advanced 11.24%. The MSCI EAFE Index of developed-market international equities rose 2.74%, while the MSCI Emerging Markets Index declined fractionally. In the U.S., the blue-chip Dow Jones Industrial Average^® advanced 20.76%, while the broader U.S. equity market, as represented by the S&P 500^® Index, gained 17.91%.

Fund Performance

For the 12-month period ended September 30, 2018, Calvert International Equity Fund (the Fund) returned 4.02% for Class A shares at net asset value (NAV), outperforming the MSCI EAFE Index (the Index), which returned 2.74%. Stock selection was the

major contributor to outperformance during the period. Sector allocation detracted from relative performance. The Fund, rather than making strategic sector allocations, uses a bottom-up, stock selection strategy that focuses on the strengths of each prospective investment. Looking at sector attribution, however, the leading contributors during the period were largely in the information technology, health care, and consumer sectors. Over the 12 months, the Fund increased the proportion of its investments in these sectors relative to the benchmark.

Calvert’s environmental, social, and governance (ESG) mandate means the Fund is limited to what it may hold in the energy and materials sectors. During the period, when oil prices rebounded strongly, the Fund’s underweight in the energy sector was the largest detractor from relative performance.

The largest individual contributor, Don Quijote Holdings Co. Ltd. (Don Quijote), continued to be one of the best managed Japanese retail companies. The acquisition of 20% of Uny, another Japanese retailer, produced positive results that surprised the market and led to the belief that Don Quijote may increase its ownership position in the future.

Lonza Group AG (Lonza), in the health care sector, was another leading contributor. Calvert initiated a position in Lonza in early 2018 following a drop in the company’s stock price. Lonza’s long-term strategy appears very promising. Calvert believes the company’s use of capital and new investments in cell, viral, and antibody therapies may help increase value.

Kering SA, a French luxury goods company that owns Gucci, further contributed to returns during the period. The strength of the rejuvenation of the Gucci brand surprised the market and led to unexpectedly strong earnings.

ING Groep NV (ING), a Dutch bank, was a detractor during the period as European banks performed poorly in general. In addition, ING agreed to a settlement with Dutch authorities over money-laundering charges that entailed a fine and management changes, including the replacement of its chief financial officer.

Continental AG, a German automotive supplier, also detracted from Fund performance. The company surprised the market with a warning in August 2018 that its profits would be significantly lower than anticipated as a result of increasingly weak auto markets and internal operational issues.

ConvaTec Group plc (ConvaTec), a medical products and technologies company that the Fund bought in hopes of a turnaround, was a major detractor. Calvert sold its position in ConvaTec during the period because of ongoing operational and management problems. Those assets were reallocated to buy Coloplast A/S., a significantly higher-performing competitor in the past.

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.

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 (April 1, 2018 to September 30, 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.

Class I	$1,000.00	$1,020.31	$4.81**	0.95%
* 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 183/365 (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 March 31, 2018.
** Absent a waiver and/or reimbursement of expenses by affiliates, expenses would be higher.

NOTES TO FINANCIAL STATEMENTS

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.

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

Level 1 - quoted prices in active markets for identical securities

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

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

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

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

Equity Securities. Equity securities (including warrants and rights) listed on a U.S. securities exchange generally are valued at the last sale or closing price as reported by an independent pricing service on the primary market or exchange on which they are traded and are categorized as Level 1 in the hierarchy. Equity securities listed on the NASDAQ 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 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 debt securities of sufficient credit quality purchased with remaining maturities of sixty days or less for which a valuation from a third party pricing service is not readily available may be valued at amortized cost, which approximates fair value, and are categorized as Level 2 in the hierarchy.

18www.calvert.com CALVERT INTERNATIONAL EQUITY FUND ANNUAL REPORT

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 following table summarizes the market value of the Fund’s holdings as of September 30, 2018, based on the inputs used to value them:

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

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.

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.

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.

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.

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, CIM’s parent company, through the end of 2019.

NOTE 4 — DISTRIBUTIONS TO SHAREHOLDERS AND INCOME TAX INFORMATION

The tax character of distributions declared for the years ended September 30, 2018 and September 30, 2017 was as follows:

	Year Ended September 30,
	2018		2017
Ordinary income		$3,294,126		$8,454,529

During the year ended September 30, 2018, accumulated loss was decreased by $105,942,269 and paid-in capital was decreased by $105,942,269 due to expired capital loss carryforwards. These reclassifications had no effect on the net assets or net asset value per share of the Fund.

As of September 30, 2018, the components of distributable earnings (accumulated loss) on a tax basis were as follows:

Undistributed ordinary income	$2,103,841
Capital loss carryforwards and deferred capital losses	($32,019,365	)
Net unrealized appreciation (depreciation)	$19,786,996

At September 30, 2018, the Fund, for federal income tax purposes, had capital loss carryforwards of $10,386,632 and deferred capital losses of $21,632,733 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, 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, 2018, $9,129,251 are short-term and $12,503,482 are long term.

Under tax regulations, capital losses incurred in taxable years beginning after December 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 September 30, 2018, as determined on a federal income tax basis, were as follows:

Aggregate cost		$171,792,488
Gross unrealized appreciation		$25,081,971
Gross unrealized depreciation	(5,293,144)
Net unrealized appreciation (depreciation)		$19,788,827

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 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 upon contractual terms. Non-cash collateral, if any, is held by the lending agent on behalf of the Fund and cannot be sold or re-pledged by the Fund; accordingly, such collateral is not reflected in the Statement of Assets and Liabilities.

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

22www.calvert.com CALVERT INTERNATIONAL EQUITY FUND ANNUAL REPORT

At September 30, 2018, the total value of securities on loan was $9,609,101 and the total value of collateral received was $10,069,359, comprised of cash of $1,696,404 and U.S. Government and/or agencies securities of $8,372,955.

The following table provides a breakdown of securities lending transactions accounted for as secured borrowings, the obligations by class of collateral pledged, and the remaining contractual maturity of those transactions as of September 30, 2018.

	Remaining Contractual Maturity of the Transactions
	Overnight and Continuous		<30 days		30 to 90 days		>90 days		Total
Securities Lending Transactions
Common Stocks		$10,069,359		$—		$—		$—		$10,069,359

The carrying amount of the liability for deposits for securities loaned at September 30, 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 September 30, 2018.

NOTE 6 — LINE OF CREDIT

The Fund participates with other funds managed by CRM in a $62.5 million committed ($25 million committed and $25 million uncommitted prior to August 7, 2018) unsecured line of credit agreement with SSB, which is in effect through August 6, 2019. 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 1.00% (1.25% prior to August 7, 2018) per annum. A commitment fee of 0.20% (0.25% prior to August 7, 2018) per annum is incurred on the unused portion of the committed facility. An administrative fee of $37,500 was incurred in connection with the renewal of the facility in August 2018. 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 borrowings outstanding pursuant to this line of credit at September 30, 2018. The Fund did not have any significant borrowings or allocated fees during the year ended September 30, 2018.

NOTE 7 — AFFILIATED COMPANIES

The Fund has invested a portion of its assets designated for high social impact investments in notes (the “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 the Notes.

www.calvert.com CALVERT INTERNATIONAL EQUITY FUND ANNUAL REPORT 23

In addition to the Notes, a Fund may also invest in companies that are considered affiliated companies because the Fund has direct or indirect ownership of, control of, or voting power of 5 percent or more of the outstanding voting shares of the company, or the company is under common ownership or control with the Fund. At September 30, 2018, the value of the Fund’s investment in the Notes and affiliated companies was $4,561,451, which represents 2.39% of the Fund’s net assets. Transactions in the Notes and affiliated companies by the Fund for the year ended September 30, 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.

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).

Proxy Voting. The Proxy Voting Guidelines that each Calvert fund uses to determine how to vote proxies relating to portfolio securities is provided as an Appendix to the fund’s Statement of Additional Information. The Statement of Additional Information can be obtained free of charge by calling the Calvert funds at 1-800-368-2745, by visiting the Calvert funds’ website at www.calvert.com or visiting the SEC’s website at www.sec.gov. Information regarding how a Calvert fund voted proxies relating to portfolio securities during the most recent 12-month period ended June 30 is available by calling Calvert funds, by visiting the Calvert funds’ website at www.calvert.com or by visiting the SEC’s website at www.sec.gov.

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.

MANAGEMENT’S DISCUSSION OF FUND PERFORMANCE¹ 

Economic and Market Conditions

U.S. stocks led the way with double-digit gains in the 12-month period ended September 30, 2018, while global stocks delivered mixed results.

U.S. stocks opened the period on the upswing, as investors anticipated and then cheered passage of the Republican tax reform package in December 2017. Sharp cuts in corporate taxes, a key element of the bill, raised corporate-profit expectations. Stocks also got a boost from positive U.S. economic data, including the unemployment rate which fell to a 17-year low.

Stocks pulled back in February 2018 amid fears that rising rates would spur inflation and boost the appeal of fixed-income investments at the expense of stocks. After a brief rebound, equity markets weakened in the spring of 2018, as investors confronted the prospect of a global trade war due to President Trump’s imposition of broad new tariffs. The tariffs drew retaliatory action from impacted countries including China, Canada, and certain countries in the European Union.

Stocks bounced back in the final three months of the period. Technology stocks led the advance, overcoming an earlier setback from a wave of data-privacy scandals. U.S. economic indicators remained largely positive throughout the period, prompting the U.S. Federal Reserve to raise its benchmark interest rate three times over the 12-month span.

Overseas equity markets delivered mixed results in the period. After early strength aided by rising corporate profits, European stocks subsequently pulled back amid mounting trade war concerns, before a partial recovery in the final months of the period. Similarly, after early gains, China entered a prolonged stock slump that reached bear market territory in late June 2018. Besides trade war fears, signs of slowing economic growth also weighed on Chinese stocks.

For the 12-month period ended September 30, 2018, all major U.S. stock indexes recorded double-digit gains. The blue-chip Dow Jones Industrial Average^®2 advanced 20.76%, while the broader U.S. equity market, as represented by the S&P 500^® Index, rose 17.91%. The technology-laden NASDAQ Composite Index surged 25.17% in the period. Large-cap U.S. stocks as measured by the S&P 500^® Index generally outperformed their small-cap counterparts as measured by the Russell 2000^® Index during the period. Growth stocks as a group outpaced value stocks in both the large- and small-cap categories, as measured by the Russell growth and value indexes.

Fund Performance

For the 12-month period ended September 30, 2018, Calvert Mid-Cap Fund (the Fund) had a total return of 15.04% for Class A shares at net asset value (NAV), outperforming the Russell Midcap^® Index (the Index), which returned 13.98%.

Stock selection in the materials, health care, and financials sectors contributed to the Fund’s outperformance relative to the Index. Stock selection in the industrials and energy sectors and an underweight to the energy sector detracted.

GoDaddy, Inc., an Internet domain registrar and web-hosting company in the information technology sector, was the largest individual contributor during the period. Business momentum was strong as the company successfully executed its margin growth and international expansion plans. Small business trends supported the company’s strategy to bring more customers into the digital age by helping them build their own websites.

Advanced Micro Devices, Inc. (Advanced Micro Devices)⁷, a semiconductor manufacturer in the information technology sector, was also a leading contributor. One of the company’s main competitors reported operational issues, including capacity constraints, which provided Advanced Micro Devices an opportunity to gain market share. The company’s strong product lineup in central processing unit cards also positioned it well for the holiday season.

lululemon athletica, inc. (lululemon),⁷ in the consumer discretionary sector, further contributed to the Fund’s outperformance relative to the Index. New management reinvigorated the brand and expanded the athletic apparel company’s direct-to-consumer product offerings. The company’s underlying growth trends were strong in athleisure attire, and lululemon performed well in other high-growth segments, such as menswear and Asian markets during the period.

Newell Brands, Inc.,⁷ in the consumer discretionary sector, was the largest detractor during the period. The company posted disappointing organic revenue growth and fell short of market expectations. Investors grew frustrated with management’s inability to increase earnings after it overpaid for and failed to extract value from a recent acquisition.

Multi-Color Corp., a global label maker for consumer products in the industrials sector, was also a leading detractor. The company was under pressure as the market had grown frustrated with management’s missteps in recent acquisitions. Investors also questioned management’s ability to execute its strategy of consolidating the print labeling industry.

Deluxe Corp. (Deluxe),⁷ a marketing company specializing in small businesses and financial institutions, was also a notable detractor. Although we believed that the secular decline in Deluxe’s paper check business could be contained and that cash flow and margin goals were achievable, the company was unable to meet expectations. With its core business in decline during the period, management does not appear to have a sound plan for

vertical growth.

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.

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 (April 1, 2018 to September 30, 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 (4/1/18)	ENDING ACCOUNT VALUE (9/30/18)	EXPENSES PAID DURING PERIOD* (4/1/18 - 9/30/18)	ANNUALIZED EXPENSE RATIO
Actual
Class A	$1,000.00	$1,102.50	$6.38**	1.21%
Class C	$1,000.00	$1,098.50	$10.31**	1.96%
Class I	$1,000.00	$1,104.60	$4.54**	0.86%
Hypothetical
(5% return per year before expenses)
Class A	$1,000.00	$1,019.00	$6.12**	1.21%
Class C	$1,000.00	$1,015.24	$9.90**	1.96%
Class I	$1,000.00	$1,020.76	$4.36**	0.86%
* 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 183/365 (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 March 31, 2018.
** Absent a waiver and/or reimbursement of expenses by affiliates, expenses would be higher.

NOTES TO FINANCIAL STATEMENTS

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 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.

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

Level 1 - quoted prices in active markets for identical securities

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

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

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

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

Equity Securities. Equity securities (including warrants and rights) listed on a U.S. securities exchange generally are valued at the last sale or closing price as reported by an independent pricing service on the primary market or exchange on which they are traded and are categorized as Level 1 in the hierarchy. Equity securities listed on the NASDAQ 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.

Short-Term Debt Securities. Short-term debt securities with a remaining maturity at time of purchase of more than sixty days are valued on the basis of valuations provided by a third party pricing service. Such securities are generally categorized as Level 2 in the hierarchy. Short-term debt securities of sufficient credit quality purchased with remaining maturities of sixty days or less are valued at amortized cost, which approximates fair value, and are categorized as Level 2 in the hierarchy.

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 following table summarizes the market value of the Fund’s holdings as of September 30, 2018, based on the inputs used to value them:

Assets	Level 1			Level 2		Level 3(1)		Total
Common Stocks	$	262,315,915	(2)	$	—	$	—	$	262,315,915

Total Investments	$	265,488,665		$	2,520,864	$	654,321	$	268,663,850
(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.

Level 3 investments at the beginning and/or end of the period in relation to net assets were not significant and accordingly, a reconciliation of Level 3 assets for the year ended September 30, 2018 is not presented.

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

C. Share Class Accounting: Realized and unrealized gains and losses 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.

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 is included at the end of the Schedule of Investments.

F. Distributions to Shareholders: Distributions to shareholders are recorded by the Fund on ex-dividend date. 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.

www.calvert.com CALVERT MID-CAP FUND ANNUAL REPORT 19

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.

NOTE 2 — RELATED PARTY TRANSACTIONS

The investment advisory fee is earned by Calvert Research and Management (CRM), a subsidiary of Eaton Vance Management (EVM), as compensation for investment advisory services rendered to the Fund.

For the year ended September 30, 2018, the investment advisory fee amounted to $1,661,954 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 year ended September 30, 2018, CRM waived or reimbursed expenses of $236,426.

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 year ended September 30, 2018, CRM was paid administrative fees of $306,786, of which $4,910 were waived.

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 were for personal services and/or the maintenance of shareholder accounts. Distribution and service fees paid or accrued for the year ended September 30, 2018 amounted to $391,739 and $172,632 for Class A shares and Class C shares, respectively.

The Fund was informed that EVD received $17,439 and its portion of the sales charge on sales of Class A shares and $1,297 of contingent deferred sales charges paid by the Fund shareholders for the year ended September 30, 2018.

EVM provides sub-transfer agency and related services to the Fund pursuant to a Sub-Transfer Agency Support Services Agreement. For the year ended September 30, 2018, sub-transfer agency fees and expenses incurred to EVM amounted to $65,764 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

20www.calvert.com CALVERT MID-CAP FUND ANNUAL REPORT

compensation of $75,000, which is being reimbursed by Calvert Investment Management, Inc. (CIM), the Calvert funds’ former investment adviser, and Ameritas Holding Company CIM’s parent company, through the end of 2019. For the year ended September 30, 2018, the Fund’s allocated portion of such expense and reimbursement was $5,317, which are included in miscellaneous expense and reimbursement of expenses-other, respectively, on the Statement of Operations.

NOTE 3 — INVESTMENT ACTIVITY

During the year ended September 30, 2018, the cost of purchases and proceeds from sales of investments, other than short-term securities, were $158,499,710 and $187,005,211, respectively.

NOTE 4 — DISTRIBUTIONS TO SHAREHOLDERS AND INCOME TAX INFORMATION

The tax character of distributions declared for the years ended September 30, 2018 and September 30, 2017 was as follows:

	Year Ended September 30,
	2018		2017
Ordinary income		$10,271,655		$2,378,020
Long-term capital gains		$13,433,194	$—

During the year ended September 30, 2018, distributable earnings was decreased by $1,658,262 and paid-in capital was increased by $1,658,262 due to the Fund’s use of equalization accounting. Tax equalization accounting allows the Fund to treat as a distribution that portion of redemption proceeds representing a redeeming shareholder’s portion of undistributed taxable income and net capital gains. These reclassifications had no effect on the net assets or net asset value per share of the Fund.

As of September 30, 2018, the components of distributable earnings (accumulated loss) on a tax basis were as follows:

Undistributed ordinary income	$7,213,067
Undistributed long-term capital gains	$7,018,355
Net unrealized appreciation (depreciation)	$33,607,894

The cost and unrealized appreciation (depreciation) of investments of the Fund at September 30, 2018, as determined on a federal income tax basis, were as follows:

Aggregate cost		$235,055,956
Gross unrealized appreciation		$38,144,096
Gross unrealized depreciation	(4,536,202		)
Net unrealized appreciation (depreciation)		$33,607,894

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 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 upon contractual terms. Non-cash collateral, if any, is held by the lending agent on behalf of the Fund and cannot be sold or re-pledged by the Fund; accordingly, such collateral is not reflected in the Statement of Assets and Liabilities.

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

www.calvert.com CALVERT MID-CAP FUND ANNUAL REPORT 21

At September 30, 2018, the total value of securities on loan was $23,077,292 and the total value of collateral received was $23,467,914, comprised of cash of $3,172,750 and U.S. Government and/or agencies securities of $20,295,164.

The following table provides a breakdown of securities lending transactions accounted for as secured borrowings, the obligations by class of collateral pledged, and the remaining contractual maturity of those transactions as of September 30, 2018.

	Remaining Contractual Maturity of the Transactions
	Overnight and Continuous		<30 days		30 to 90 days		>90 days		Total
Securities Lending Transactions
Common Stocks		$23,467,914		$—		$—		$—		$23,467,914

The carrying amount of the liability for deposits for securities loaned at September 30, 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 September 30, 2018.

NOTE 6 — LINE OF CREDIT

The Fund participates with other funds managed by CRM in a $62.5 million committed ($25 million committed and $25 million uncommitted prior to August 7, 2018) unsecured line of credit agreement with SSB, which is in effect through August 6, 2019. 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 1.00% (1.25% prior to August 7, 2018) per annum. A commitment fee of 0.20% (0.25% prior to August 7, 2018) per annum is incurred on the unused portion of the committed facility. An administrative fee of $37,500 was incurred in connection with the renewal of the facility in August 2018. 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 borrowings outstanding pursuant to this line of credit at September 30, 2018. The Fund did not have any significant borrowings or allocated fees during the year ended September 30, 2018.

NOTE 7 — AFFILIATED COMPANIES

The Fund has invested a portion of its assets designated for high social impact investments in notes (the 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.

At September 30, 2018, the value of the Fund’s investment in the Notes was $2,520,864, which represents 0.9% of the Fund’s net assets. Transactions in the Notes by the Fund for the year ended September 30, 2018 were as follows:

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

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Directors

Calvert World Values Fund, Inc.:

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities of Calvert Mid-Cap Fund (the Fund), a series of Calvert World Values Fund, Inc., including the schedule of investments, as of September 30, 2018, the related statement of operations for the year then ended, the statements of changes in net assets for each of the years in the two‑year period then ended, and the related notes (collectively, the financial statements) and the financial highlights for each of the years in the five‑year period then ended. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of September 30, 2018, the results of its operations for the year then ended, the changes in its net assets for each of the years in the two‑year period then ended, and the financial highlights for each of the years in the five‑year period then ended, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

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

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Such procedures also included confirmation of securities owned as of September 30, 2018, by correspondence with custodians and brokers. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. We believe that our audits provide a reasonable basis for our opinion.

• 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.

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.

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).

Proxy Voting. The Proxy Voting Guidelines that each Calvert fund uses to determine how to vote proxies relating to portfolio securities is provided as an Appendix to the fund’s Statement of Additional Information. The Statement of Additional Information can be obtained free of charge by calling the Calvert funds at 1-800-368-2745, by visiting the Calvert funds’ website at www.calvert.com or visiting the SEC’s website at www.sec.gov. Information regarding how a Calvert fund voted proxies relating to portfolio securities during the most recent 12-month period ended June 30 is available by calling Calvert funds, by visiting the Calvert funds’ website at www.calvert.com or by visiting the SEC’s website at www.sec.gov.

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.

MANAGEMENT’S DISCUSSION OF FUND PERFORMANCE¹ 

Economic and Market Conditions

Led by higher U.S. stocks, most global stock indexes advanced during the 12-month period ended September 30, 2018.

U.S. stocks opened the period on the upswing as investors anticipated, and then cheered passage of the Republican tax reform package in December 2017. Sharp cuts in corporate taxes - a key element of the bill - raised corporate-profit expectations. Stocks also got a boost from positive U.S. economic data, including the unemployment rate, which fell to a 17-year low.

Early in the period, global stocks followed U.S. stocks sharply higher. European stocks got a boost from growing economies and rising corporate profits across the region. Key equity indexes in the Asia-Pacific region also rose despite tensions with North Korea. China’s stock market advanced behind an accelerating housing market, rising retail sales, and strong foreign trade.

U.S. stocks pulled back in February 2018 amid fears that rising rates would spur inflation and boost the appeal of fixed-income investments at the expense of stocks. After a brief rebound, equity markets weakened in the spring of 2018, as investors confronted the prospect of a global trade war due to President Trump’s imposition of broad new tariffs. The protectionist move drew retaliatory action from impacted countries including China, Canada, and certain countries in the European Union.

European stocks also pulled back even more substantially amid mounting trade war concerns, before a partial recovery in the final months of the period. In China, signs of a slowing economy compounded trade war concerns, sending Chinese stocks into a prolonged slump that reached bear market territory in late June 2018.

U.S. stocks bounced back strongly in the final three months of the period. Technology stocks led the advance, overcoming an earlier setback from a wave of data-privacy scandals. U.S. economic indicators remained largely positive throughout the period, prompting the U.S. Federal Reserve to raise its benchmark interest rate three times over the 12-month span.

For the 12-month period ended September 30, 2018, the MSCI World Index,² a proxy for global equities, advanced 11.24%. The MSCI EAFE Index of developed-market international equities rose 2.74%, while the MSCI Emerging Markets Index declined fractionally. In the U.S., the blue-chip Dow Jones Industrial Average^® advanced 20.76%, while the broader U.S. equity market, as represented by the S&P 500^® Index, gained 17.91%.

Fund Performance

For the 12-month period ended September 30, 2018, Calvert International Opportunities Fund (the Fund) had a total return of 7.62% for Class A shares at net asset value (NAV), outperforming its benchmark, the MSCI EAFE SMID Cap Index (the Index), which returned 3.80%.

Strong stock selection accounted for most of the Fund’s outperformance during the period. Although the Fund does not seek

to outperform by favoring or avoiding specific regions or sectors, strong stock selection in Europe and Japan enhanced performance during the period. On a sector basis, holdings in the financials, health care, and information technology sectors contributed positively while an underweight and stock selection in the energy sector detracted slightly.

At the stock level, the top contributor to performance was the sporting goods manufacturer Amer Sports Oyj (Finland). The company owns several strong brands in the sporting goods industry, including Salomon, Arc’teryx, Wilson, and Suunto. While the stock price performed well for much of the period as the strategic direction and operating environment for the company continued to improve, it was a takeover bid from ANTA Sports Products, Ltd. (Hong Kong) in September that led to a sharp increase in Amer Sports’ share price. The position was then sold when the valuation no longer looked attractive.

Asahi Intecc Co. Ltd. (Japan), a medical device company specializing in guide wires for angioplasty, was also a notable contributor. Investors responded favorably after the company reported strong sales and profit growth for its 2017 fiscal year. Sales were particularly strong outside of Japan and margins were ample despite an increase in research and development spending. The market also welcomed the company’s promotion to the first section of the Tokyo Stock Exchange at the end of the reporting period, a move that could lead to an expansion of the investor base.

Moncler SpA (Italy), a luxury‑apparel maker well‑known for high‑end down jackets, was another positive contributor. The company increased its retail presence and extended its global footprint while maintaining high margins and investor returns. The company also began to selectively expand its business beyond winter apparel to areas such as knitwear, in which it can capitalize on its desirable brand recognition.

IWG plc (Switzerland), a global provider of rented office space and related services, was the largest detractor during the period. Shares dropped sharply because of a profit warning attributed to disruption in the London market and elsewhere. Calvert’s lack of confidence that the company’s mature business would recover was among several factors that led to the sale of IWG plc during the period.

The share price of Inchcape plc (U.K.), the largest independent automobile distributor and retailer in the world, was also under pressure during the period. Fears of cyclical headwinds across the auto sector and, in particular, some of Inchcape’s key trading regions ─ the U.K., Singapore, and Australia ─ made investors cautious and resulted in a relatively weak share price.

Confectionary company Morinaga & Co. Ltd. (Japan) was another detractor from performance. With its share price having performed well for more than two years, the maker of the popular Hi-Chew fruit candy saw its earnings clipped as it faced higher costs from raw materials, advertising, and logistics. Shares were also weakened by investor skepticism about the company’s future investment plans.

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.

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 (April 1, 2018 to September 30, 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 (4/1/18)	ENDING ACCOUNT VALUE (9/30/18)	EXPENSES PAID DURING PERIOD* (4/1/18 - 9/30/18)	ANNUALIZED EXPENSE RATIO
Actual

Class C	$1,000.00	$994.00	$10.55	2.11%
Class I	$1,000.00	$998.40	$5.56	1.11%

(5% return per year before expenses)
Class A	$1,000.00	$1,018.25	$6.88	1.36%
Class C	$1,000.00	$1,014.49	$10.66	2.11%
Class I	$1,000.00	$1,019.50	$5.62	1.11%
* 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 183/365 (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 March 31, 2018.

NOTES TO FINANCIAL STATEMENTS

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 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.

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

Level 1 - quoted prices in active markets for identical securities

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

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

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

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

Equity Securities. Equity securities (including warrants and rights) listed on a U.S. securities exchange generally are valued at the last sale or closing price as reported by an independent pricing service on the primary market or exchange on which they are traded and are categorized as Level 1 in the hierarchy. Equity securities listed on the NASDAQ 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 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 debt securities of sufficient credit quality purchased with remaining maturities of sixty days or less for which a valuation from a third party pricing service is not readily available may be valued at amortized cost, which approximates fair value, and are categorized as Level 2 in the hierarchy.

www.calvert.com CALVERT INTERNATIONAL OPPORTUNITIES FUND ANNUAL REPORT 19

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.

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 following table summarizes the market value of the Fund’s holdings as of September 30, 2018, based on the inputs used to value them:

Assets	Level 1		Level 2			Level 3(1)		Total

Level 3 investments at the beginning and/or end of the period in relation to net assets were not significant and accordingly, a reconciliation of Level 3 assets for the year ended September 30, 2018 is not presented.

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

C. Share Class Accounting: Realized and unrealized gains and losses 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.

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

20www.calvert.com CALVERT INTERNATIONAL OPPORTUNITIES FUND ANNUAL REPORT

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.

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.

NOTE 2 — RELATED PARTY TRANSACTIONS

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 1.43%, 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 year ended September 30, 2018, CRM, EVAIL and EVMI waived or reimbursed no expenses.

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 year ended September 30, 2018, CRM was paid administrative fees of $308,195.

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.

www.calvert.com CALVERT INTERNATIONAL OPPORTUNITIES FUND ANNUAL REPORT 21

assets attributable to Class C shares for providing ongoing distribution services and facilities to the Fund. In addition, pursuant to the Class C Plan, the Fund also makes payments of service fees to EVD, financial intermediaries and other persons in amounts equal to 0.25% per annum of its average daily net assets attributable to that class. Service fees paid or accrued are for personal services and/or the maintenance of shareholder accounts. Distribution and service fees paid or accrued for the year ended September 30, 2018 amounted to $149,261 and $69,433 for Class A shares and Class C shares, respectively.

The Fund was informed that EVD received $37,615 as its portion of the sales charge on sales of Class A shares for the year ended September 30, 2018.

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, CIM’s parent company, through the end of 2019. For the year ended September 30, 2018, the Fund’s allocated portion of such expense and reimbursement was $5,247, which are included in miscellaneous expense and reimbursement of expenses-other, respectively, on the Statement of Operations.

NOTE 3 — INVESTMENT ACTIVITY

During the year ended September 30, 2018, the cost of purchases and proceeds from sales of investments, other than short-term securities, were $219,128,268 and $151,175,028, respectively.

NOTE 4 — DISTRIBUTIONS TO SHAREHOLDERS AND INCOME TAX INFORMATION

The tax character of distributions declared for the years ended September 30, 2018 and September 30, 2017 was as follows:

	Year Ended September 30,
	2018		2017
Ordinary income		$15,146,341		$2,608,931

During the year ended September 30, 2018, distributable earnings was decreased by $1,967,819 and paid-in capital was increased by $1,967,819 due to the Fund’s use of equalization accounting. Tax equalization accounting allows the Fund to treat as a distribution that portion of redemption proceeds representing a redeeming shareholder’s portion of undistributed taxable income and net capital gains. These reclassifications had no effect on the net assets or net asset value per share of the Fund.

As of September 30, 2018, the components of distributable earnings (accumulated loss) on a tax basis were as follows:

Undistributed ordinary income	$11,108,212
Undistributed long-term capital gains	$12,059,229
Net unrealized appreciation (depreciation)	$20,977,330

22www.calvert.com CALVERT INTERNATIONAL OPPORTUNITIES FUND ANNUAL REPORT

The cost and unrealized appreciation (depreciation) of investments of the Fund at September 30, 2018, as determined on a federal income tax basis, were as follows:

Aggregate cost		$281,956,961
Gross unrealized appreciation		$29,594,044
Gross unrealized depreciation	(8,607,241)
Net unrealized appreciation (depreciation)		$20,986,803

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 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 upon contractual terms. Non-cash collateral, if any, is held by the lending agent on behalf of the Fund and cannot be sold or re-pledged by the Fund; accordingly, such collateral is not reflected in the Statement of Assets and Liabilities.

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

At September 30, 2018, the total value of securities on loan was $15,623,280 and the total value of collateral received was $16,306,454, comprised of cash of $7,422,626 and U.S. Government and/or agencies securities of $8,883,828.

The following table provides a breakdown of securities lending transactions accounted for as secured borrowings, the obligations by class of collateral pledged, and the remaining contractual maturity of those transactions as of September 30, 2018.

	Remaining Contractual Maturity of the Transactions
	Overnight and Continuous		<30 days		30 to 90 days		>90 days		Total
Securities Lending Transactions
Common Stocks		$16,306,454		$—		$—		$—		$16,306,454

The carrying amount of the liability for deposits for securities loaned at September 30, 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 September 30, 2018.

NOTE 6 — LINE OF CREDIT

The Fund participates with other funds managed by CRM in a $62.5 million committed ($25 million committed and $25 million uncommitted prior to August 7, 2018) unsecured line of credit agreement with SSB, which is in effect through August 6, 2019. 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 1.00% (1.25% prior to August 7, 2018) per annum. A commitment fee of 0.20% (0.25% prior to August 7, 2018) per annum is incurred on the unused portion of the committed facility. An administrative fee of $37,500 was incurred in connection with the renewal of the facility in August 2018. 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 borrowings outstanding pursuant to this line of credit at September 30, 2018. The Fund did not have any significant borrowings or allocated fees during the year ended September 30, 2018.

NOTE 7 — AFFILIATED COMPANIES

The Fund has invested a portion of its assets designated for high social impact investments in notes (the 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 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.

At September 30, 2018, the value of the Fund’s investment in the Notes was $962,350, which represents 0.32% of the Fund’s net assets. Transactions in the Notes by the Fund for the year ended September 30, 2018 were as follows:

Name of Issuer	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

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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Directors

Calvert World Values Fund, Inc.:

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities of Calvert International Opportunities Fund (the Fund), a series of Calvert World Values Fund, Inc., including the schedule of investments, as of September 30, 2018, the related statement of operations for the year then ended, the statements of changes in net assets for each of the years in the two‑year period then ended, and the related notes (collectively, the financial statements) and the financial highlights for each of the years in the five‑year period then ended. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of September 30, 2018, the results of its operations for the year then ended, the changes in its net assets for each of the years in the two‑year period then ended, and the financial highlights for each of the years in the five‑year period then ended, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

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

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Such procedures also included confirmation of securities owned as of September 30, 2018, by correspondence with custodians and brokers. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. We believe that our audits provide a reasonable basis for our opinion.

We have served as the auditor of one or more of the Calvert Funds since 2002.

In addition, our Privacy Policy applies only to those Calvert customers who are individuals and who have a direct relationship with us.

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).

The Proxy Voting Guidelines that each Calvert fund uses to determine how to vote proxies relating to portfolio securities is provided as an Appendix to the fund’s Statement of Additional Information. The Statement of Additional Information can be obtained free of charge by calling the Calvert funds at 1-800-368-2745, by visiting the Calvert funds’ website at www.calvert.com or visiting the SEC’s website at www.sec.gov. Information regarding how a Calvert fund voted proxies relating to portfolio securities during the most recent 12-month period ended June 30 is available by calling Calvert funds, by visiting the Calvert funds’ website at www.calvert.com or by visiting the SEC’s website at www.sec.gov.

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.

MANAGEMENT’S DISCUSSION OF FUND PERFORMANCE¹ 

Economic and Market Conditions

Emerging market equities moved into negative territory during the 12-month period ended September 30, 2018, returning -0.81% as measured by the MSCI Emerging Markets Index (the Index)². Emerging markets, which underperformed developed markets during the period, were weighed down by concerns over a tighter U.S. monetary policy, the strength of the U.S. dollar, elevated oil prices, the potential impact of a global trade war, a slowdown in Chinese growth, and a rising 10-year U.S. Treasury yield.

China underperformed during the period as the U.S. implemented tariffs on $250 billion worth of Chinese imports. China retaliated with measures of its own during a period when Chinese macroeconomic data disappointed. These escalating tensions contributed to weakness across a number of emerging markets.

Those markets vulnerable to tightening global liquidity came under the most pressure. Turkey had the weakest performance among emerging countries, dropping 41.66%. The Turkish lira fell more than 45% as a result of a bitter dispute with the U.S. that exacerbated investor concerns over macro imbalances, regional inflation, policy mismanagement, and a seemingly powerless central bank. The Philippines, Indonesia, and South Africa also underperformed.

Meanwhile, Thailand recorded robust returns, with companies in the financials and energy sectors among the best performers. Taiwan also stood out, supported by the strong performance of semiconductor stocks. Despite the threat of U.S. sanctions, Russian equities benefited from rising crude oil prices, helping that market finish ahead of the Index.

At the sector level, energy significantly outperformed the Index, surging 26.95% on the strength of increased oil prices. The consumer discretionary sector fell 14.75% amid fears of a potential trade war.

Fund Performance

For the 12-month period ended September 30, 2018, Calvert Emerging Markets Equity Fund (the Fund) had a total return of -4.62% for Class A shares at net asset value (NAV), underperforming the Index, which returned -0.81%. The underperformance was primarily due to country allocation, notably an overweight to China, which detracted from returns because of the substantial weakening of the renminbi during the period. This eclipsed the positive contribution from stock selection in the country. Stock selection in Taiwan, Brazil, Russia, and India also detracted.

The Fund’s position in Techtronic Industries Co. Ltd. (Techtronic), a Hong Kong-listed manufacturer of home

improvement equipment, was a leading contributor to returns relative to the Index. Techtronic rose after reporting very strong first-half 2018 results, which included better-than-projected earnings by both its divisions. The power tools division grew at its fastest pace in more than a decade while its floor-care division reported an unexpectedly strong rebound in sales. AIA Group Ltd. (AIA), a Hong Kong-listed insurer, moved higher as a result of strong growth across all regions, most notably China.

Turnarounds in Singapore and Thailand also produced strong results, as did AIA’s resilient business line in Hong Kong. Tech Mahindra Ltd., an Indian information technology services provider, rose on the strength of its quarterly revenue and operational results in the second quarter of the Fund’s fiscal year.

Magnit PJSC (Magnit), a Russian discount retailer, was a notable detractor from Fund performance during the period. Poor results were worsened by news that one of Magnit’s majority owners had sold shares in 2017. Based on disappointing returns and challenging market conditions, the Fund sold its position in the company during the period.

Ultrapar Participacoes SA (Ultrapar), a Brazilian fuel distributor, fell on weak results for the first nine months of 2018. Performance was hurt by increased competition in the fuel market from independent gas stations able to import cheaper fuel and poor management of its reseller network. Ultrapar also slowed business expansion as it worked to make its capital allocation model more sustainable. Another detractor, BB Seguridade Participacoes SA, a Brazilian insurer, announced reduced earnings largely stemming from pension contributions.

The Fund’s country allocations included an overweight to China, India, the United Arab Emirates, and Taiwan. The Fund was underweight in South Korea, South Africa, Malaysia, Thailand, and Poland. Major changes included raising the overweight to China and moving to underweight South Africa by switching out of Naspers Ltd. into Tencent Holdings Ltd. The Fund moved from an overweight to an underweight position in Brazil. It exited Turkey during the period, selling ownership in Arcelik AS, a Turkish manufacturer of white goods, because of challenging market conditions.

At the sector level, the Fund remained overweight in information technology, consumer discretionary, and financials. It was underweight in the energy, materials, and communication services sectors.

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.

Important Notice to Shareholders

At a special meeting of shareholders held October 5, 2018, shareholders of the Fund approved (i) an investment sub-advisory agreement between Calvert Research and Management (“CRM”) and Hermes Investment Management Limited (“Hermes”) pursuant to which Hermes will continue to serve as sub-adviser to the Fund and (ii) a “manager of managers” structure, which would allow CRM and the Fund to enter into and materially amend investment sub-advisory agreements with unaffiliated sub-advisers and certain affiliated sub-advisers without obtaining additional shareholder approval, subject to certain conditions. Prior to reliance on a “manager of managers” structure, CRM and Calvert World Values Fund, Inc. would need to apply for and be granted exemptive relief from the SEC.

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 (April 1, 2018 to September 30, 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 (4/1/18)	ENDING ACCOUNT VALUE (9/30/18)	EXPENSES PAID DURING PERIOD* (4/1/18 - 9/30/18)	ANNUALIZED EXPENSE RATIO

Class R6	$1,000.00	$876.70	$4.33**	0.92%
Hypothetical
(5% return per year before expenses)

Class R6	$1,000.00	$1,020.46	$4.66**	0.92%
* 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 183/365 (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 March 31, 2018.
** Absent a waiver and/or reimbursement of expenses by affiliates, expenses would be higher.

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 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.

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

Level 1 - quoted prices in active markets for identical securities

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

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

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

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

Equity Securities. Equity securities (including warrants and rights) listed on a U.S. securities exchange generally are valued at the last sale or closing price as reported by an independent pricing service on the primary market or exchange on which they are traded and are categorized as Level 1 in the hierarchy. Equity securities listed on the NASDAQ 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 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.

Short-Term Debt Securities. Short-term debt securities with a remaining maturity at time of purchase of more than sixty days are valued on the basis of valuations provided by a third party pricing service. Such securities are generally categorized as Level 2 in the hierarchy. Short-term debt securities of sufficient credit quality purchased with remaining maturities of sixty days or less are valued at amortized cost, which approximates fair value, and are categorized as Level 2 in the hierarchy.

Other Securities. Participatory notes are valued based on the value of the underlying equity security as determined using the valuation techniques for equity securities listed above. Participatory notes are categorized as Level 2 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.

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 following table summarizes the market value of the Fund’s holdings as of September 30, 2018, based on the inputs used to value them:

(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 and capital gains, if any, have been provided for in accordance with the Fund’s understanding of the applicable country’s tax rules and rates. Distributions received that represent a return of capital are recorded as a reduction of cost of investments. Distributions received that represent a capital gain are recorded as a realized gain. Interest income, which includes amortization of premium and accretion of discount on debt securities, is accrued as earned.

C. Share Class Accounting: Realized and unrealized gains and losses 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

20www.calvert.com CALVERT EMERGING MARKETS EQUITY FUND ANNUAL REPORT

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.

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. 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 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.

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.

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.

www.calvert.com CALVERT EMERGING MARKETS EQUITY FUND ANNUAL REPORT 21

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 year ended September 30, 2018, CRM waived or reimbursed expenses of $3,129,354. A portion of the expenses waived or reimbursed was borne by Hermes.

The administrative fee is earned by CRM as compensation for administrative services rendered to the Fund. The fee is computed at an annual rate of 0.12% of the Fund’s average daily net assets attributable to Class A, Class C, Class I and Class R6 (and 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 year ended September 30, 2018, CRM was paid administrative fees of $1,006,194, of which $18,274 were waived.

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 year ended September 30, 2018 amounted to $350,932 and $169,866 for Class A shares and Class C shares, respectively.

The Fund was informed that EVD received $85,607 as its portion of the sales charge on sales of Class A shares. The Fund was also informed that EVD received $7,497 of contingent deferred sales charges (CDSC) paid by Class C shareholders and no CDSC paid by Class A shareholders for the year ended September 30, 2018.

EVM provides sub-transfer agency and related services to the Fund pursuant to a Sub-Transfer Agency Support Services Agreement. For the year ended September 30, 2018, sub-transfer agency fees and expenses incurred to EVM amounted to $54,031 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, CIM’s parent company, through the end of 2019. For the year ended September 30, 2018, the Fund’s allocated portion of such expense and reimbursement was $15,907, which are included in miscellaneous expense and reimbursement of expenses-other, respectively, on the Statement of Operations.

NOTE 3 — INVESTMENT ACTIVITY

During the year ended September 30, 2018, the cost of purchases and proceeds from sales of investments, other than short-term securities, were $1,225,626,884 and $219,089,713, respectively.

NOTE 4 — DISTRIBUTIONS TO SHAREHOLDERS AND INCOME TAX INFORMATION

The tax character of distributions declared for the years ended September 30, 2018 and September 30, 2017 was as follows:

	Year Ended September 30,
	2018		2017
Ordinary income		$1,239,205		$888,499

During the year ended September 30, 2018, accumulated loss was increased by $1,638,191 and paid-in capital was increased by $1,638,191 due to the Fund’s use of equalization accounting. Tax equalization accounting allows the Fund to treat as a distribution that portion of redemption proceeds representing a redeeming shareholder’s portion of undistributed taxable income and net capital gains. These reclassifications had no effect on the net assets or net asset value per share of the Fund.

As of September 30, 2018 the components of distributable earnings (accumulated loss) on tax basis were as follows:

Undistributed ordinary income	$10,412,457
Deferred capital losses	($7,907,354	)
Net unrealized appreciation (depreciation)	($61,870,458	)

At September 30, 2018, the Fund, for federal income tax purposes, had deferred capital losses of $7,907,354 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, 2018, $7,907,354 are short-term.

The cost and unrealized appreciation (depreciation) of investments of the Fund at September 30, 2018, as determined on a federal income tax basis, were as follows:

Aggregate cost		$1,245,194,722
Gross unrealized appreciation		$54,349,660
Gross unrealized depreciation	(115,995,528)
Net unrealized appreciation (depreciation)		($61,645,868	)

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 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 upon contractual terms. Non-cash collateral, if any, is held by the lending agent on behalf of the Fund and cannot be sold or re-pledged by the Fund; accordingly, such collateral is not reflected in the Statement of Assets and Liabilities.

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

At September 30, 2018, the total value of securities on loan was $666,312 and the total value of collateral received was $688,831, comprised of cash.

The following table provides a breakdown of securities lending transactions accounted for as secured borrowings, the obligations by class of collateral pledged, and the remaining contractual maturity of those transactions as of September 30, 2018.

	Overnight and Continuous		<30 days		30 to 90 days		>90 days		Total
Securities Lending Transactions
Common Stocks		$688,831		$—		$—		$—		$688,831

The carrying amount of the liability for deposits for securities loaned at September 30, 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 September 30, 2018.

NOTE 6 — LINE OF CREDIT

The Fund participates with other funds managed by CRM in a $62.5 million committed ($25 million committed and $25 million uncommitted prior to August 7, 2018) unsecured line of credit agreement with SSB, which is in effect through August 6, 2019. 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 1.00% (1.25% prior to August 7, 2018) per annum. A commitment fee of 0.20% (0.25% prior to August 7, 2018) per annum is incurred on the unused portion of the committed facility. An administrative fee of $37,500 was incurred in connection with the renewal of the facility in August 2018. 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 borrowings outstanding pursuant to this line of credit at September 30, 2018. The Fund did not have any significant borrowings or allocated fees during the year ended September 30, 2018.

NOTE 7 — AFFILIATED COMPANIES

The Fund has invested a portion of its assets designated for high social impact investments in notes (the 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.

At September 30, 2018, the value of the Fund’s investment in the Notes was $1,924,700, which represents 0.1% of the Fund’s net assets. Transactions in the Notes by the Fund for the year ended September 30, 2018 were as follows:

Name of Issuer	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

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.

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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Directors

Calvert World Values Fund, Inc:

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities of Calvert Emerging Markets Equity Fund (the Fund), a series of Calvert World Values Fund, Inc., including the schedule of investments, as of September 30, 2018, the related statement of operations for the year then ended, the statements of changes in net assets for each of the years in the two‑year period then ended, and the related notes (collectively, the financial statements) and the financial highlights for each of the years or periods in the five‑year period then ended. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of September 30, 2018, the results of its operations for the year then ended, the changes in its net assets for each of the years in the two‑year period then ended, and the financial highlights for each of the years or periods in the five‑year period then ended, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

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

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Such procedures also included confirmation of securities owned as of September 30, 2018, by correspondence with custodians and brokers. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. We believe that our audits provide a reasonable basis for our opinion.

We have served as the auditor of one or more of the Calvert Funds since 2002.

SPECIAL MEETING OF SHAREHOLDERS

The Fund held a Special Meeting of Shareholders on Friday, October 5, 2018 for the following purposes: (1) to approve an investment sub-advisory agreement between Calvert Research and Management (“CRM”) and Hermes Investment Management Limited (“Hermes”) pursuant to which Hermes will continue to serve as sub-adviser to the Fund and (2) to approve a “manager of managers” structure, which would allow CRM and the Fund to enter into and materially amend investment sub-advisory agreements with unaffiliated sub-advisers and certain affiliated sub-advisers without obtaining additional shareholder approval, subject to certain conditions. Prior to reliance on a “manager of managers” structure, CRM and Calvert World Values Fund, Inc. would need to apply for and be granted exemptive relief from the SEC.

The shareholder meeting results are as follows:

	Number of Shares
	For	Against/Withhold	Abstain(1)
Proposal One	36,097,731	647,076	1,124,221
Proposal Two	34,622,275	2,053,840	1,192,913

⁽¹⁾ Abstained shares (i.e., proxies from brokers or nominees indicating that such persons have not received instructions from the beneficial owner or other person entitled to vote shares on a particular matter with respect to which the brokers or nominees do not have discretionary power) were treated as shares that were present at the meeting for purposes of establishing a quorum, but had the effect of a vote against the Proposal.

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).

Proxy Voting. The Proxy Voting Guidelines that each Calvert fund uses to determine how to vote proxies relating to portfolio securities is provided as an Appendix to the fund’s Statement of Additional Information. The Statement of Additional Information can be obtained free of charge by calling the Calvert funds at 1-800-368-2745, by visiting the Calvert funds’ website at www.calvert.com or visiting the SEC’s website at www.sec.gov. Information regarding how a Calvert fund voted proxies relating to portfolio securities during the most recent 12-month period ended June 30 is available by calling Calvert funds, by visiting the Calvert funds’ website at www.calvert.com or by visiting the SEC’s website at www.sec.gov.

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

Item 4. Principal Accountant Fees and Services

In determining whether to pre-approve non-audit services, the Audit Committee considers whether the services are consistent with maintaining the independence of the auditors. The Committee may delegate its authority to pre-approve certain matters to one or more of its members. In this regard, the Committee has delegated authority jointly to the Audit Committee Chair together with another Committee member with respect to non-audit services not exceeding $25,000 in each instance. In addition, the Committee has pre-approved the retention of the auditors to provide tax-related services related to the tax treatment and tax accounting of newly acquired securities, upon request by the investment adviser in each instance.
