Dear Shareholder:

Over the 12 months ended September 30, 2007, the U.S. and international equity markets fluctuated dramatically, moving from a fairly steady upward climb during the first half of the period to marked volatility in the third quarter of this year. In July, turmoil from the subprime mortgage market spilled over into stock markets at home and abroad as subprime lenders and other financial institutions worldwide suffered declines and investors became increasingly risk averse.

Despite the subprime woes, the overall U.S. stock market, as measured by the Standard & Poor's 500 Index, climbed a healthy 16.44% for the 12-month period. International stock markets, however, outpaced the U.S., demonstrating resilience despite high energy prices, inflationary pressures, and other global concerns. The Morgan Stanley Capital International (MSCI) Europe Australasia Far East (EAFE) Index, a benchmark for non-U.S. stocks, returned 25.38%, boosted in part by a weak U.S. dollar. Emerging markets, however, again outshone other regions, as many of these countries continued to enjoy growing consumer demand.

A Look at the Subprime Situation

The volatility in the global stock markets this summer was caused by the turmoil in the subprime mortgage market. Many of these mortgages were packaged into securities of varying complexity. Some of these received top credit ratings and were purchased by financial firms, including hedge funds and investment banks, around the world. When default rates for the underlying mortgages started to increase much more quickly than expected, some holders of the securities were forced to mark down their values.

A Reevaluation of Risk

The unexpected declines in value forced the liquidation of several high-profile hedge funds, hurt the stock prices of financial companies, and generally caused investors to reevaluate risk in the global stock and bond markets. While these events may seem unsettling, we view them as a normal correction in the equity and financial markets, returning to the traditionally lower prices seen for riskier assets. In recent years, investors had been irrationally paying as much for riskier stocks as for higher-quality stocks in the hopes of earning a little more return. Also, volatility in the stock market had been near historic lows. Now, in this more cautious environment, we see opportunities for larger-cap and higher-quality stocks to shine.

Calvert Conducts Climate Change Survey

In early 2007, Calvert conducted an on-line survey of shareholders and clients to help us sharpen the focus and assess the relevance of the environmental, social, and governance criteria that we use to evaluate companies for our socially responsible portfolios.

More than 1,500 Calvert shareholders responded to the survey on climate change and other environmental concerns. Of those responding, 97% said the leading reason they chose socially responsible funds was to invest in companies with good environmental practices. Also, climate change topped the list of socially responsible investors' concerns, and 90% of investors said that their unease about climate change has increased over the last five years.

Two New Funds Debut

Partially in response to these results, Calvert launched the Calvert Global Alternative Energy Fund on May 31, 2007. The Fund, which is managed by Dublin-based KBC Asset Management International Ltd., invests in a broad universe of U.S. and non-U.S. stocks that are significantly involved in the alternative energy industry. The Fund offers investors the opportunity to address the urgent issue of climate change while investing in one of the fastest-growing market sectors globally. Keep in mind, however, that this is a sector fund, which means it is likely to be volatile over time. It's important that investors in this Fund have a long-term perspective and time horizon.

In addition, Calvert launched the Calvert International Opportunities Fund, managed by London-based subadvisor F&C Management Limited, on May 31. This Fund seeks long-term capital appreciation by investing in growth-oriented small-cap and mid-cap foreign stocks. Coupled with the Calvert World Values International Equity Fund, which invests in large-cap foreign stocks, the Calvert International Opportunities Fund gives Calvert investors access to the full range of market capitalizations in foreign companies.

Calvert Continues to Grow

Also during the reporting period, Calvert surpassed $15 billion in total assets under management. As we continue to grow, Calvert remains committed to striving to maximize the performance of our funds in terms of both financial returns to shareholders and returns to society as a whole.

Thank you for your continued confidence in our mutual funds, and we look forward to continuing our endeavor to meet your investment needs in the future.

Sincerely,

Barbara J. Krumsiek
President and CEO

Social Update
from the Calvert Social Research Department

The work of Calvert's Social Research Department and our unique investment programs continue to demonstrate Calvert's leadership in socially responsible investment practices. This Social Update highlights key initiatives and involvement for the 12-month reporting period ended September 30, 2007.

Shareholder Advocacy

Shareholder resolutions have been a key tool in enhancing shareholders' communications with the companies they invest in for more than three decades--but now that tool is in serious jeopardy as the Securities and Exchange Commission (SEC) evaluates making changes to the shareholder resolution process. As a result, Calvert Group has been playing a major role in the campaign to preserve shareholder rights this year. We have expressed our strong opposition to the SEC in formal comments on several alternative proposals. In September, Paul Hilton, Calvert Director of Advanced Equities Research, along with other members of the Social Investment Forum, spent a day lobbying members of Congress on the issue. Calvert also participated in a press event to bring public attention to this issue.

We believe the SEC's proposed alternatives would severely undermine shareholders' rights to submit resolutions that raise environmental, governance, and social issues. In fact, Calvert believes that, instead of rolling back investors' rights, the Commission ought to move in the other direction and allow shareholders to submit a wider range of resolutions. We will continue to actively work toward a favorable resolution of this issue.

The Results of This Year's Campaign

Our 2007 proxy season was our most successful one yet. We filed or co-filed an all-time high of 36 shareholder resolutions encouraging the companies in our portfolios to change their policies on issues ranging from employee diversity to climate-change reporting. Of these, 20 were withdrawn after companies agreed to make changes in these areas. Of the 11 that have been voted upon, two resolutions received more than 50% of the vote--our best showing ever. One of the resolutions was for Unisys Corp. on disclosure of political contributions and the other was for HCC Insurance Holdings on employee diversity.1 Four more resolutions received about one-third of the vote or higher, which is still a remarkably high number. For more information on the proxy votes, please visit www.calvert.com, select "Socially Responsible Investing" and click on "Shareholder Advocacy."

Political Contributions

As the 2008 elections draw near, we have increased our focus on corporate political contributions. We believe it is important for companies to ensure that political activity is conducted with integrity as part of a strong and enforceable code of conduct, and that political spending is fully disclosed to shareholders. In fact, five of the shareholder resolutions we filed this year called for companies to report all types of political contributions. One received a vote of 52% (Unisys), and three--Hewlett-Packard Co., Pfizer, and Medtronic-- were withdrawn successfully after those companies decided to make the disclosures. In one case, the resolution was withdrawn after the company was acquired.

Special Equities

A modest but important portion of certain Funds is allocated for venture capital investment in innovative companies that are developing for-profit products or services that address important social or environmental issues. Illinois-based Sword Diagnostics is one such investment. Sword's technology reduces the time for food manufacturers to detect the presence of potentially deadly listeria bacteria by one-third--so they can act to stop the contamination within hours instead of two to three days.2 In New York, Marrone Organic Innovations is tackling one of the biggest hurdles to lowering the cost and increasing the availability of organically grown food--creating effective, natural products for pest management.3 Specifically, the company creates new products to control weeds, pests, and other plant diseases using naturally occurring microorganisms it has identified.

Sudan Divestment

Calvert Group's work toward ending the atrocities in Darfur continues. On October 3, Calvert Senior Vice President of Social Research and Policy, Bennett Freeman, delivered testimony to the U.S. Senate Committee on Banking, Housing, and Urban Affairs about how asset managers can use targeted divestment to increase economic and political pressure on the Khartoum government in ways consistent with their fiduciary responsibilities. We also continue to lend analytical and advocacy support to the Sudan Divestment Task Force (SDTF) and the Save Darfur Coalition (SDC), with whom we formed relationships earlier this year.

Community Investments

Many of our Funds participate in Calvert's High Social Impact Investing (HSII) program, which is administered through the Calvert Social Investment Foundation. This community investment program may allocate up to 1% to 3% of Fund assets at below-market interest rates to investments that provide economic opportunity for struggling populations.4

During the reporting period, the Calvert Social Investment Foundation invested in Tides Shared Spaces, a program of the Tides nonprofit network, to help develop a nonprofit office center in New York City using a "green" architectural plan. This shared-space facility will provide stable rental rates for a number of nonprofits as well as conference center facilities and opportunities for tenant collaboration and sharing. Tides has already established a similar center in San Francisco.

As a result of the HSII program, eBay-owned MicroPlace has chosen the Calvert Foundation's Community Investment Note program as one of the first securities issuers for its new microfinance business.5 The MicroPlace Web site allows the public to invest in various institutions that provide small loans to impoverished entrepreneurs around the world. This is a major innovation--harnessing the power of the Internet to exponentially expand and revolutionize the practice of microfinance investing. You should feel proud that your investment in the Calvert Funds was instrumental in the establishment of this groundbreaking online marketplace.

As always, we appreciate your investment in Calvert mutual funds and will continue to manage your investments with an eye on both financial performance and corporate

integrity.

Portfolio Management Discussion

Raymond Mui
of Acadian Asset Management, Inc.

Investment Performance

Calvert World Values International Equity Fund Class A shares (at NAV*) returned a strong 21.72% for the 12-month period ended September 30, 2007, but trailed the benchmark Morgan Stanley Capital International (MSCI) Europe Australasia Far East (EAFE) Index, which gained 25.38%. While the Fund had many solid stock picks for the period, it was stocks the Fund did not hold in several key countries that accounted for the Fund's relative underperformance.

Investment Climate

International markets finished the period firmly in positive territory, demonstrating resilience despite high energy prices, inflationary pressures, and other global concerns. The sharp drops in Chinese stocks that triggered a global sell-off in late February had little lasting impact on markets. But summer troubles in the U.S. subprime mortgage industry and the ensuing global credit crunch overshadowed generally solid fundamentals such as good economic growth and strong corporate earnings.

For much of August, stock prices appeared to lose their normal relationship to underlying fundamentals. Many quantitative strategies struggled in this environment, although many had at least partially recovered by month-end. In general, a weakening dollar resulted in significantly higher returns for international stocks when returns were calculated in U.S. dollars rather than the local currency.

Performance in European equity markets was solid as they collectively gained 28.1% in U.S.-dollar terms.1 German stocks rose 47.9% due to record levels of business confidence and employment, increasing consumer and investment spending, and strong exports. Helped by similar dynamics, including a 25-year low in unemployment, France gained 25.1%. Italy advanced a more modest 19.4%, and Spain rose 31.6%. Spanish stocks were buoyed by strong consumer demand, housing market, and construction activity. The United Kingdom also made notable gains, returning 22.5% despite interest rates at a six-year high of 5.75% dampening the housing market.

The Asia-Pacific region returned 19.5% in U.S.-dollar terms. Japan continued to trail its Asian counterparts, posting a 7.2% gain. The weaker yen had a positive impact on exports--particularly in the auto industry--but declining household spending and mounting concerns about the impact of a potential economic slowdown in a key trade market such as the U.S. held back returns. Elsewhere in the region, Singapore rose 63.8%, Australia gained 57.4%, and New Zealand was up 38.9%.

Emerging markets also made solid gains, rising 58.72% as commodity prices soared and private consumption in many markets continued to improve. Latin American markets fared best, collectively rising 71.9%. Brazil was a big contributor with a 97.9% return, helped by robust exports and economic conditions that boosted consumer spending. Exports drove Peru's stock market to an impressive 132.3% gain. In Asia, China rose 134.4% as the government took measures to cool the economy, and India was up 63.2%. In Eastern Europe, Turkey was the top performer at 86.3%, benefiting from steady exports, strengthening consumer sentiment, and labor market improvements.

Portfolio Strategy

Stock selection drove the Portfolio's underperformance relative to the benchmark, along with underweightings to two strong-performing countries.

It was the stocks the Fund did not hold in the U.K., the Netherlands, and France that were particularly costly over the past year. In the U.K., the Fund did not hold expanding telecommunications company Vodafone Group, or metals and mining stocks BHP Billiton and Rio Tinto. In France, the Fund did not have a position in energy giant Total. And lacking Netherlands-based ABN-AMRO Bank also hurt relative returns as the stock surged amid active acquisition discussions.

On the other hand, stock selection added value through investments in Germany's Volkswagen, steel manufacturers Voest-Alpine (Austria) and Rautaruukki Corp. (Finland), Finnish machinery producer Metso Corp., and Japan's Nikon Corp.

Overall, country allocations were negative. While an overweighting to Finland and underweighting to Japan boosted returns, an underweighting to Australia and lack of exposure to Hong Kong more than negated those benefits. Opportunistic allocations to the U.S. and Canada, as well as to a selection of emerging markets such as Korea and Taiwan, contributed positively to performance during the period.

Outlook

In our opinion, markets appear to have recovered from the steepest losses stemming from the U.S. subprime fallout and ensuing global turmoil. We expect elevated market volatility to continue, but do not see this as the start of a prolonged market meltdown. Overall, economic growth and corporate earnings are providing a solid base for equity markets in many parts of the world to recover, once the problems with specific stocks and industries linked to the credit problems are absorbed.

Heightened volatility means that there will likely be a broader range of returns going forward, both within markets and across markets. This type of environment is ripe for active stock selection and underscores the importance of global diversification.

We continue to be positive on Europe as a whole, expecting continued growth over the long term, though moderated from the levels seen in recent years. Sectors we like the most in this region include energy, autos, and food/staples retailing, but we see technology as less attractive. For countries, we favor the United Kingdom, although the unusually high transaction costs of U.K. stocks tend to reduce the number that end up in our portfolios, so this area is likely to remain underweighted.

Our short-term forecast for Japan remains negative due to high valuations, but over the longer term we continue to expect moderate growth in this market amid mostly positive economic data. Australia, New Zealand, Hong Kong, and Singapore are all attractive markets in the Australasian region.

Many emerging markets are positively ranked within our framework, with Asia as the region with the most positive forecast. Overall, we expect it to be another solid year for global equities.

Performance Comparison

Comparison of change in value of $10,000 investment.

Average annual total returns in the Portfolio Statistics above and the Performance Comparison line graph are with maximum load deducted -- they assume reinvestment of dividends and reflect the deduction of the Fund's Class A maximum front-end sales charge of 4.75%, or deferred sales charge, as applicable. No sales charge has been applied to the index used for comparison. However, the Lipper average does reflect the deduction of the category's average front-end sales charge. The value of an investment in Class A shares is plotted in the line graph. The value of an investment in another class of shares would be different. New subadvisor assumed management of the Fund effective March 2006, and previously in March 2002. The graph and table do not reflect the deduction of taxes that a shareholder would pay on the Fund's distributions or the redemption of Fund shares. Past performance is no guarantee of future results.

Shareholder Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) and redemption fees; and (2) ongoing costs, including management fees; distribution (12b-1) fees; and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

This Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (April 1, 2007 to September 30, 2007).

Actual Expenses

The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, 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 line 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 line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual 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 the 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. Therefore, the second line 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 have been higher.

* Expenses are equal to the Fund's annualized expense ratio of 1.58%, 2.51%, 2.38% and 0.94% for Class A, Class B, Class C and Class I, respectively, multiplied by the average account value over the period, multiplied by 183/365.

Note A -- Significant Accounting Policies

General: The Calvert World Values International Equity Fund (the "Fund"), a series of Calvert World Values Fund, Inc., is registered under the Investment Company Act of 1940 as a diversified, open-end management investment company. The operation of each series is accounted for separately. The Fund offers four classes of shares of capital stock. Class A shares are sold with a maximum front-end sales charge of 4.75%. Class B shares are sold without a front-end sales charge. With certain exceptions, the Fund will impose a deferred sales charge at the time of redemption, depending on how long investors have owned the shares. Class C shares are sold without a front-end sales charge. With certain exceptions, the Fund will impose a deferred sales charge on shares sold within one year of purchase. Class B and Class C shares have higher levels of expenses than Class A shares. Class I shares require a minimum account balance of $1,000,000. The $1 million minimum initial investment may be waived for certain institut ional accounts, where it is believed to be in the best interest of the Fund and its shareholders. Class I shares have no front-end or deferred sales charge and have lower levels of expenses than Class A shares. Each class has different: (a) dividend rates, due to differences in Distribution Plan expenses and other class-specific expenses, (b) exchange privileges and (c) class-specific voting rights.

Security 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 to value its investments wherever possible. Securities for which market quotations are available are valued at last sale price or official closing price on the primary market or exchange in which they trade. Foreign securities are valued based on quotations from the principal market in which such securities are normally traded. If events occur after the close of the principal market in which foreign securities are traded, and before the Fund's net asset value is determined, that are expected to materially affect the value of those securities, then they are valued at their fair value taking these events into account. Short-term notes are stated at amortized cost, which approximates fair value. The Fund may invest in securities whose resale is subje ct to restrictions. Investments for which market quotations are not available or deemed not reliable are fair valued in good faith under the direction of the Board of Directors.

The Fund has retained a third party fair value pricing service to quantitatively analyze the price movement of its holdings on foreign exchanges and to automatically fair value if the variation from the prior day's closing price exceeds specified parameters.

In determining fair value, the Board considers all relevant qualitative and quantitative information available. These factors are subject to change over time and are reviewed periodically. The values assigned to fair value investments are based on available information and do not necessarily represent amounts that might ultimately be realized. Further, because of the inherent uncertainty of valuation, those estimated values may differ significantly from the values that would have been used had a ready market for the investments existed, and the differences could be material.

At September 30, 2007, securities valued at $9,292,961 or 1.2% of net assets, were fair valued in good faith under the direction of the Board of Directors.

Repurchase Agreements: The Fund may enter into repurchase agreements with recognized financial institutions or registered broker/dealers and, in all instances, holds underlying securities with a value exceeding the total repurchase price, including accrued interest. Although risk is mitigated by the collateral, the Fund could experience a delay in recovering its value and a possible loss of income or value if the counterparty fails to perform in accordance with the terms of the agreement.

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 Fund's Statement of Net Assets.

Security Transactions and Net Investment Income: Security transactions 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 or, in the case of dividends on certain foreign securities, as soon as the Fund is informed of the ex-dividend date. Distributions received on securities that represent a return of capital or capital gain are recorded as a reduction of cost of investments and/or as a realized gain. Interest income, which includes amortization of premium and accretion of discount on debt securities, is accrued as earned. Investment income and realized and unrealized gains and losses are allocated to separate classes of shares based upon the relative net assets of each class. Expenses arising in connection with a class are charged directly to that class. Expenses common to the classes are allocated to each class in proportion to their relative net assets. Withhold ing taxes on foreign dividends have been provided for in accordance with the Fund's understanding of the applicable country's tax rules and rates.

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. The effect of changes in foreign exchange rates on securities and foreign currencies is included in the net realized and unrealized gain or loss on securities and foreign currencies.

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 generally accepted accounting principles; accordingly, periodic reclassifications are made within the Fund's capital accounts to reflect income and gains available for distribution under income tax regulations.

Estimates: The preparation of the financial statements in conformity with accounting principles generally accepted in the United States 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 income and expenses during the reported period. Actual results could differ from those estimates.

Redemption Fees: The Fund charges a 2% redemption fee on redemptions, including exchanges, made within 30 days of purchase in the same Fund (within seven days for Class I shares). The redemption fee is paid to the Class of the Fund from which the redemption is made, and is accounted for as an addition to paid-in capital. The fee is intended to discourage market-timers by ensuring that short-term trading costs are borne by the investors making the transactions and not the shareholders already in the Fund.

Expense Offset Arrangement: The Fund has an arrangement with its custodian bank whereby the custodian's fees may be paid indirectly by credits earned on the Fund's cash on deposit with the bank. These credits are used to reduce the Fund's expenses. Such a deposit arrangement may be an alternative to overnight investments.

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.

New Accounting Pronouncements: In July 2006, the Financial Accounting Standards Board (FASB) released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" -- an interpretation of FASB Statement 109 (FIN 48). FIN 48 provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken in the course of preparing the Fund's tax returns to determine whether tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax benefits of positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax expense in the current year. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. The adoption of FIN 48 is not expected to have a material impact on the Fund's financial statements.

In September 2006, the Financial Accounting Standards Board (FASB) issued Statement on Financial Accounting Standards (SFAS) No. 157, "Fair Value Measurements." This standard establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and requires additional disclosures about fair value measurements. SFAS No. 157 applies to fair value measurements already required or permitted by existing standards. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. The changes to current generally accepted accounting principles from the application of this Statement relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. As of September 30, 2007, the Fund does not believe the adoption of SFAS No. 157 will impact the financial statement amounts, however, additional disclosures may be r equired about the inputs used to develop the measurements and the effect of certain of the measurements on changes in net assets for the period.

Note B -- Related Party Transactions

Calvert Asset Management Company, Inc. (the "Advisor") is wholly-owned by Calvert Group, Ltd. ("Calvert"), which is indirectly wholly owned by UNIFI Mutual Holding Company. The Advisor provides investment advisory services and pays the salaries and fees of officers and Directors of the Fund who are employees of the Advisor or its affiliates. For its services, the Advisor receives a monthly fee based on the following annual rates of average daily net assets: .75% on the first $250 million, .725% on the next $250 million and .675% on the excess of $500 million. Under the terms of the agreement $439,634 was payable at year end. In addition, $148,677 was payable at year end for operating expenses paid by the Advisor during September 2007.

The Advisor has contractually agreed to limit net annual fund operating expenses through January 31, 2008 for Class I. The contractual expense cap is 1.10%. For the purposes of this expense limit, operating expenses do not include interest expense, brokerage commissions, taxes, and extraordinary expenses. To the extent any expense offset credits are earned, the Advisor's obligation under the contractual limitation may be reduced and the Advisor may benefit from the expense offset arrangement.

Calvert Distributors, Inc., an affiliate of the Advisor, is the distributor and principal underwriter for the Fund. Distribution Plans, adopted by Class A, Class B and Class C shares, allow the Fund to pay the Distributor for expenses and services associated with distribution of shares. The expenses paid may not exceed .35%, 1.00% and 1.00% annually of average daily net assets of each Class A, Class B and Class C, respectively. The amount actually paid by the Fund is an annualized fee, payable monthly of .25%, 1.00% and 1.00% of the Fund's average daily net assets of Class A, Class B and Class C, respectively. Class I shares do not have Distribution Plan expenses. Under the terms of agreement $167,375 was payable at year end.

The Distributor received $254,636 as its portion of commissions charged on sales of the Fund's Class A shares for the year ended September 30, 2007.

Calvert Shareholder Services, Inc. ("CSSI"), an affiliate of the Advisor, is the shareholder servicing agent for the Fund. For its services, CSSI received a fee of $229,538 for the year ended September 30, 2007. Under the terms of the agreement $19,706 was payable at year end. Boston Financial Data Services, Inc. is the transfer and dividend disbursing agent.

Calvert Administrative Services Company, an affiliate of the Advisor, provides administrative services to the Fund for an annual fee, payable monthly, of .35% for Class A, Class B and Class C shares and .15% for Class I shares, based on their average daily net assets. Under the terms of the agreement $194,114 was payable at year end.

The Fund invests in Community Investment Notes issued by the Calvert Social Investment Foundation (the "CSI Foundation"). The CSI Foundation is a 501(c)(3) non-profit organization that receives in-kind support from the Calvert Group, Ltd. and its subsidiaries. The Fund has received from the Securities and Exchange Commission an exemptive order permitting the Fund to make investments in these notes under certain conditions.

Each Director of the Fund who is not an employee of the Advisor or its affiliates receives an annual retainer of $34,000 plus $2,000 for each Board meeting attended. An additional Chair support fee of $24,000 annually is paid to the Fund Chair. Additional fees of up to $10,000 annually may be paid to the Chairperson of special committees of the Board and to the lead disinterested Director. Director's fees are allocated to each of the funds served.

Note C -- Investment Activity

During the year, cost of purchases and proceeds from sales of investments, other than short-term securities, were $683,547,763 and $576,007,734, respectively.

The cost of investments owned at September 30, 2007 for federal income tax purposes was $671,031,477. Net unrealized appreciation aggregated $129,559,515, of which $147,067,149 related to appreciated securities and $17,507,634 related to depreciated securities.

Net realized capital loss carryforwards for federal income tax purposes of $179,742 (acquired from Calvert South Africa Fund that merged into the Fund in September 2002) at September 30, 2007 may be utilized to offset future capital gains until expiration in September 2009.

The Fund's use of net capital loss carryforwards acquired from Calvert South Africa Fund may be limited under certain tax provisions.

The tax character of dividends and distributions paid during the years ended September 30, 2007, and September 30, 2006 were as follows:

Distributions paid from:	2007	2005
Ordinary income	$25,078,193	$3,648,571
Long-term capital gain	52,606,012	--
Total	$77,684,205	$3,648,571

As of September 30, 2007, the components of distributable earnings/(accumulated losses) on a tax basis were as follows:

Undistributed ordinary income	$31,200,517
Undistributed long term capital gain	31,026,726
Capital loss carryforward	(179,742)
Unrealized appreciation (depreciation)	129,559,515
	$191,607,016

The differences between the components of distributable earnings on a tax basis and the amounts reflected in the statement of net assets are primarily due to temporary book-tax differences that will reverse in a subsequent period. These book-tax differences are due to wash sales, passive foreign investment companies, partnerships, and capital loss carryover subject to limitations under Internal Revenue Code section 382.

Reclassifications, as shown in the table below, have been made to the Fund's components of net assets to reflect income and gains available for distribution (or available capital loss carryovers, as applicable) under income tax law and regulations. These reclassifications are due to permanent book-tax differences and have no impact on net assets. The primary permanent differences causing such reclassification for the Fund are due to foreign currency transactions, partnerships and foreign taxes.

Undistributed net investment income	($161,560)
Accumulated net realized gain (loss)	161,560

Note D -- Line of Credit

A financing agreement is in place with all Calvert Group Funds (except for the Calvert Social Investment Fund's Balanced and Enhanced Equity Portfolios, and the CVS Calvert Social Balanced Portfolio) and State Street Corporation ("SSC"). Under the agreement, SSC provides an unsecured line of credit facility, in the aggregate amount of $50 million ($25 million committed and $25 million uncommitted), accessible by the Funds for temporary or emergency purposes only. Borrowings under this committed facility bear interest at the overnight Federal Funds Rate plus .50% per annum. A commitment fee of .10% per annum is incurred on the unused portion of the committed facility, which is allocated to all participating funds. The Fund had $1,403,695 of outstanding borrowings at an interest rate of 5.75% at September 30, 2007.

For the year ended September 30, 2007 borrowings by the Fund under the Agreement were as follows:

TOTALS	$753,848	$848,810

Note F -- Other

In connection with certain venture capital investments, the Fund is committed to future capital calls, which will increase the Fund's investment in these securities. The aggregate amount of the future capital commitments totals $1,283,345 at September 30, 2007.

Explanation of Financial Tables

Schedule of Investments

The Schedule of Investments is a snapshot of all securities held in the fund at their market value, on the last day of the reporting period. Securities are listed by asset type (e.g., common stock, corporate bonds, U.S. government obligations) or, for International Funds, by country, and may be further broken down into sub-groups and by industry classification.

Statement of Assets and Liabilities

The Statement of Assets and Liabilities is often referred to as the fund's balance sheet. It lists the value of what the fund owns, is due and owes on the last day of the reporting period. The fund's assets include the market value of securities owned, cash, receivables for securities sold and shareholder subscriptions, and receivables for dividends and interest payments that have been earned, but not yet received. The fund's liabilities include payables for securities purchased and shareholder redemptions, and expenses owed but not yet paid. The statement also reports the fund's net asset value (NAV) per share on the last day of the reporting period. The NAV is calculated by dividing the fund's net assets (assets minus liabilities) by the number of shares outstanding. This statement is accompanied by a Schedule of Investments. Alternatively, if certain conditions are met, a Statement of Net Assets may be presented in lieu of this statement and the Schedule of Investments.

Statement of Net Assets

The Statement of Net Assets provides a detailed list of the fund's holdings, including each security's market value on the last day of the reporting period. The Statement of Net Assets includes a Schedule of Investments. Other assets are added and other liabilities subtracted from the investments total to calculate the fund's net assets. Finally, net assets are divided by the outstanding shares of the fund to arrive at its share price, or Net Asset Value (NAV) per share.

At the end of the Statement of Net Assets is a table displaying the composition of the fund's net assets. Paid in Capital is the money invested by shareholders and represents the bulk of net assets. Undistributed Net Investment Income and Accumulated Net Realized Gains usually approximate the amounts the fund had available to distribute to shareholders as of the statement date. Accumulated Realized Losses will appear as negative balances. Unrealized Appreciation (Depreciation) is the difference between the market value of the fund's investments and their cost, and reflects the gains (losses) that would be realized if the fund were to sell all of its investments at their statement-date values.

Statement of Operations

The Statement of Operations summarizes the fund's investment income earned and expenses incurred in operating the fund. Investment income includes dividends earned from stocks and interest earned from interest-bearing securities in the fund. Expenses incurred in operating the fund include the advisory fee paid to the investment advisor, administrative services fees, distribution plan expenses (if applicable), transfer agent fees, shareholder servicing expenses, custodial, legal, and audit fees, and the printing and postage expenses related to shareholder reports. Expense offsets (fees paid indirectly) are also shown. Credits earned from offset arrangements are used to reduce the fund's expenses. This statement also shows net gains (losses) realized on the sale of investments and the increase or decrease in the unrealized appreciation (depreciation) on investments held during the period.

Statement of Changes in Net Assets

The Statement of Changes in Net Assets shows how the fund's total net assets changed during the two most recent reporting periods. Changes in the fund's net assets are attributable to investment operations, distributions and capital share transactions.

The Operations section of the report summarizes information detailed in the Statement of Operations. The Distribution section shows the dividend and capital gain distributions made to shareholders. The amounts shown as distributions in this section may not match the net investment income and realized gains amounts shown in the Operations section because distributions are determined on a tax basis and certain investments or transactions may be treated differently for financial statement and tax purposes. The Capital Share Transactions section shows the amount shareholders invested in the fund, either by purchasing shares or by reinvesting distributions, and the amounts redeemed. The corresponding numbers of shares issued, reinvested and redeemed are shown at the end of the report.

Financial Highlights

The Financial Highlights table provides a per-share breakdown per class of the components that affect the fund's net asset value for current and past reporting periods. The table provides total return, total distributions, expense ratios, portfolio turnover and net assets for the applicable period. Total return is a measure of a fund's performance that encompasses all elements of return: dividends, capital gain distributions and changes in net asset value. Total return is the change in value of an investment over a given period, assuming reinvestment of any dividends and capital gain distributions, expressed as a percentage of the initial investment. Total distributions include distributions from net investment income and net realized gains. Long-term gains are earned on securities held in the fund more than one year. Short-term gains, on the sale of securities held less than one year, are treated as ordinary dividend income for tax purposes. The expense ratio is a fund's cost of doing business, ex pressed as a percentage of net assets. These expenses directly reduce returns to shareholders. Portfolio turnover measures the trading activity in a fund's investment portfolio -- how often securities are bought and sold by a fund. Portfolio turnover is affected by market conditions, changes in the size of the fund, the nature of the fund's investments and the investment style of the portfolio manager.

Dear Shareholders:

Over the 12 months ended September 30, 2007, the U.S. and international equity markets fluctuated dramatically, moving from a fairly steady upward climb during the first half of the period to marked volatility in the third quarter of this year. In July, turmoil from the subprime mortgage market spilled over into stock markets at home and abroad as subprime lenders and other financial institutions worldwide suffered declines and investors became increasingly risk averse.

Despite the subprime woes, the overall U.S. stock market, as measured by the Standard & Poor's 500 Index, climbed a healthy 16.44% for the 12-month period. U.S. mid-cap stocks were the strongest performers, followed by large-cap stocks. Small-cap stocks brought up the rear, ending a five-year stint in the leadership position. International stock markets outpaced the U.S., demonstrating resilience despite high energy prices, inflationary pressures, and other global concerns. The Morgan Stanley Capital International (MSCI) Europe Australasia Far East (EAFE) Index, a benchmark for non-U.S. stocks, returned 25.38%, boosted in part by a weak U.S. dollar. Emerging markets, however, again outshone other regions, as many of these countries continued to enjoy growing consumer demand.

A Look at the Subprime Situation

The volatility in the global stock markets this summer was caused by the turmoil in the subprime mortgage market. Many of these mortgages were packaged into securities of varying complexity. Some of these received top credit ratings and were purchased by financial firms, including hedge funds and investment banks, around the world. When default rates for the underlying mortgages started to increase much more quickly than expected, some holders of the securities were forced to mark down their values.

A Reevaluation of Risk

The unexpected declines in value forced the liquidation of several high-profile hedge funds, hurt the stock prices of financial companies, and generally caused investors to reevaluate risk in the global stock and bond markets. While these events may seem unsettling, we view them as a normal correction in the equity and financial markets, returning to the traditionally lower prices seen for riskier assets. In recent years, investors had been irrationally paying as much for riskier stocks as for higher-quality stocks in the hopes of earning a little more return. Also, volatility in the stock market had been near historic lows. Now, in this more cautious environment, we see opportunities for larger-cap and higher-quality stocks to shine.

Growth Overtakes Value

The reporting period also featured the reversal of a long trend. For the first time in nearly seven years, growth stocks outperformed value stocks, as the Russell 1000® Growth Index returned 19.35% while the Russell 1000® Value Index gained 14.45%. Many of Calvert's equity funds tend to have a growth tilt, so the continued leadership of growth stocks would be a welcome change. And given the current market environment, we believe this trend may build momentum.

Calvert Conducts Climate Change Survey

In early 2007, Calvert conducted an on-line survey of shareholders and clients to help us sharpen the focus and assess the relevance of the environmental, social, and governance criteria that we use to evaluate companies for our socially responsible portfolios.

More than 1,500 Calvert shareholders responded to the survey on climate change and other environmental concerns. Of those responding, 97% said the leading reason they chose socially responsible funds was to invest in companies with good environmental practices. Also, climate change topped the list of socially responsible investors' concerns, and 90% of investors said that their unease about climate change has increased over the last five years.

Two New Funds Debut

Partially in response to these results, Calvert launched the Calvert Global Alternative Energy Fund on May 31, 2007. The Fund, which is managed by Dublin-based KBC Asset Management International Ltd., invests in a broad universe of U.S. and non-U.S. stocks that are significantly involved in the alternative energy industry. The Fund offers investors the opportunity to address the urgent issue of climate change while investing in one of the fastest-growing market sectors globally. Keep in mind, however, that this is a sector fund, which means it is likely to be volatile over time. It's important that investors in this Fund have a long-term perspective and time horizon.

In addition, Calvert launched the Calvert International Opportunities Fund, managed by London-based subadvisor F&C Management Limited, on May 31. This Fund seeks long-term capital appreciation by investing in growth-oriented small-cap and mid-cap foreign stocks. Coupled with the Calvert World Values International Equity Fund, which invests in large-cap foreign stocks, the Calvert International Opportunities Fund gives Calvert investors access to the full range of market capitalizations in foreign companies.

Calvert Continues to Grow

Also during the reporting period, Calvert surpassed $15 billion in total assets under management. As we continue to grow, Calvert remains committed to striving to maximize the performance of our funds in terms of both financial returns to shareholders and returns to society as a whole.

Thank you for your continued confidence in our mutual funds, and we look forward to continuing our endeavor to meet your investment needs in the future.

Sincerely,

Barbara J. Krumsiek
President and CEO
Calvert Group, Ltd.

Social Update
from the Calvert Social Research Department

The work of Calvert's Social Research Department and our unique investment programs continue to demonstrate Calvert's leadership in socially responsible investment practices. This Social Update highlights key initiatives and involvement for the 12-month reporting period ended September 30, 2007.

Shareholder Advocacy

Shareholder resolutions have been a key tool in enhancing shareholders' communications with the companies they invest in for more than three decades--but now that tool is in serious jeopardy as the Securities and Exchange Commission (SEC) evaluates making changes to the shareholder resolution process. As a result, Calvert Group has been playing a major role in the campaign to preserve shareholder rights this year. We have expressed our strong opposition to the SEC in formal comments on several alternative proposals. In September, Paul Hilton, Calvert Director of Advanced Equities Research, along with other members of the Social Investment Forum, spent a day lobbying members of Congress on the issue. Calvert also participated in a press event to bring public attention to this issue.

We believe the SEC's proposed alternatives would severely undermine shareholders' rights to submit resolutions that raise environmental, governance, and social issues. In fact, Calvert believes that, instead of rolling back investors' rights, the Commission ought to move in the other direction and allow shareholders to submit a wider range of resolutions. We will continue to actively work toward a favorable resolution of this issue.

The Results of This Year's Campaign

Our 2007 proxy season was our most successful one yet. We filed or co-filed an all-time high of 36 shareholder resolutions encouraging the companies in our portfolios to change their policies on issues ranging from employee diversity to climate-change reporting. Of these, 20 were withdrawn after companies agreed to make changes in these areas. Of the 11 that have been voted upon, two resolutions received more than 50% of the vote--our best showing ever. One of the resolutions was for Unisys Corp. on disclosure of political contributions and the other was for HCC Insurance Holdings on employee diversity.1 Four more resolutions received about one-third of the vote or higher, which is still a remarkably high number. For more information on the proxy votes, please visit www.calvert.com, select "Socially Responsible Investing" and click on "Shareholder Advocacy."

Political Contributions

As the 2008 elections draw near, we have increased our focus on corporate political contributions. We believe it is important for companies to ensure that political activity is conducted with integrity as part of a strong and enforceable code of conduct, and that political spending is fully disclosed to shareholders. In fact, five of the shareholder resolutions we filed this year called for companies to report all types of political contributions. One received a vote of 52% (Unisys), and three--Hewlett-Packard Co., Pfizer, and Medtronic-- were withdrawn successfully after those companies decided to make the disclosures. In one case, the resolution was withdrawn after the company was acquired.

Special Equities

A modest but important portion of certain Funds is allocated for venture capital investment in innovative companies that are developing for-profit products or services that address important social or environmental issues. Illinois-based Sword Diagnostics is one such investment. Sword's technology reduces the time for food manufacturers to detect the presence of potentially deadly listeria bacteria by one-third--so they can act to stop the contamination within hours instead of two to three days.2 In New York, Marrone Organic Innovations is tackling one of the biggest hurdles to lowering the cost and increasing the availability of organically grown food--by creating effective, natural products for pest management.3 Specifically, the company creates new products to control weeds, pests, and other plant diseases using naturally occurring microorganisms it has identified.

Sudan Divestment

Calvert Group's work toward ending the atrocities in Darfur continues. On October 3, Calvert Senior Vice President of Social Research and Policy, Bennett Freeman, delivered testimony to the U.S. Senate Committee on Banking, Housing, and Urban Affairs about how asset managers can use targeted divestment to increase economic and political pressure on the Khartoum Government in ways consistent with their fiduciary responsibilities. We also continue to lend analytical and advocacy support to the Sudan Divestment Task Force (SDTF) and the Save Darfur Coalition (SDC), with whom we formed relationships earlier this year.

Community Investments

Many of our Funds participate in Calvert's High Social Impact Investing (HSII) program, which is administered through the Calvert Social Investment Foundation. This community investment program may allocate up to 1% to 3% of Fund assets at below-market interest rates to investments that provide economic opportunity for struggling populations.4

During the reporting period, the Calvert Social Investment Foundation invested in Tides Shared Spaces, a program of the Tides nonprofit network, to help develop a nonprofit office center in New York City using a "green" architectural plan. This shared-space facility will provide stable rental rates for a number of nonprofits as well as conference center facilities and opportunities for tenant collaboration and sharing. Tides has already established a similar center in San Francisco.

As a result of the HSII program, eBay-owned MicroPlace has chosen the Calvert Foundation's Community Investment Note program as one of the first securities issuers for its new microfinance business.5 The MicroPlace website allows the public to invest in various institutions that provide small loans to impoverished entrepreneurs around the world. This is a major innovation--harnessing the power of the Internet to exponentially expand and revolutionize the practice of microfinance investing. You should feel proud that your investment in the Calvert Funds was instrumental in the establishment of this groundbreaking online marketplace.

As always, we appreciate your investment in Calvert mutual funds and will continue to manage your investments with an eye on both financial performance and corporate integrity.

Investment Performance

In the 12 months ended September 30, 2007, the Calvert Capital Accumulation Fund Class A shares (at NAV*) gained a solid 17.03%. This compared to 21.22% for the Russell Midcap® Growth Index. Disappointing results from stocks in several key sectors caused the Fund's underperformance relative to its benchmark.

Investment Climate

As U.S. economic growth continued to slow, the New Year ushered in the reversal of trends that had dominated the equity markets for more than five years: small-cap stocks outperforming mid- and large-cap stocks, and value leading growth. In fact, mid-cap stocks had the strongest performance for the one-year period, gaining 17.9% versus 16.9% for large-caps and 12.3% for small-caps.1 The Russell Midcap® Growth Index topped the Russell Midcap® Value Index by more than seven percentage points for the period.2

Throughout the year, strong global growth and a weak U.S. dollar boosted exports and contributed to generally strong U.S. corporate earnings. Deepening worries about the mortgage market and troubles of a few high-profile hedge funds caused an equity-market downturn and increased volatility in July. As many hedge funds rushed to reduce their leveraged positions, a wholesale sell-off of equities occurred. High-quality assets were sold alongside lower-quality assets, so high-quality assets were not the short-term safe haven they often are. There seemed to be no safe place to hide. But the Federal Reserve acted in August and September to restore calm.

Portfolio Strategy

Our core strategy employs a valuation model which seeks to identify reasonably priced companies with better-than-average forecast growth and profitability. We then subject the companies with high expected returns to rigorous scrutiny of their fundamentals.

Portfolio Changes

Over the past 12 months, we bought and sold 19 stocks. We replaced XTO Energy, which had grown outside the mid-cap range, with St. Mary Land & Exploration Co. We also sold Cimarex Energy Co. to reduce our Energy position. We sold several holdings to limit our exposure to the weakening home-building market: Eagle Materials, industrial-fluids firm Graco, KB Home, and Pulte Homes. We replaced them with Donaldson Co., a producer of filtration systems; Genlyte Group, a lighting fixture manufacturer; and Middleby Corp., a commercial kitchen supplier.

In Health Care, we sold pharmacy-services provider Omnicare due to the deteriorating quality of its fundamentals, taking advantage of a temporary sell-off to replace it with Laboratory Corporation of America Holdings. We also bought gynecological-diagnostics company Cytyc Corp. and subsequently sold it on news that it would be acquired. Financials holding First Marblehead Corp., a provider of outsourcing services for private education lenders, replaced SLM Corp. (Sallie Mae), which faces an increasingly challenging regulatory environment. Five stocks in a variety of sectors were sold after successfully reaching their price target.

Key Performance Factors

Our overweight to the Materials sector and underweight to the Consumer Discretionary sector helped returns, but underweights to Industrials and Energy detracted from performance. Stock selection was strong in Technology, Health Care, and Consumer Staples, but weak in Industrials, Energy, and Financials.

Three Technology holdings--Itron (66.8% return), ANSYS (54.7%), and Mettler-Toledo International (54.2%)3--were buoyed by strong earnings reports throughout the year. Hansen Natural Corp. gained 69.3% due to a robust beverage-product pipeline and distribution savvy. Reliance Steel & Aluminum Co. traded 77% higher as commodity prices reached new heights. Strayer Education, our largest holding at the end of the period, rose 57.4% due to increasing enrollments and higher tuitions. Health-care companies Cytyc (72.6%) and Dionex (56.0%) also outperformed.

On the other hand, three Industrials stocks struggled with slowing economic growth: WESCO International (-26.0%), Pacer International (-29.7%), and Genlyte (-26.6%). In Financials, First Marblehead (-30.9%) sank after its two largest clients agreed to jointly acquire a competitor. Energy holding St. Mary Land & Exploration declined 4.3% despite rising oil and gas prices.

Market Outlook

At this point, the full economic ramifications of the subprime-mortgage woes are unclear. We believe that U.S. economic growth, as measured by gross domestic product (GDP), should slow to between 2.25% and 2.5% in the second half of 2007. Core inflation should remain at 2% or less, although headline inflation may run higher given that oil prices are above $80 a barrel. Overall, we believe stock valuations remain reasonable and should allow the market to rise modestly before year-end.

In 2008, we expect another year of controlled inflation and modest growth for the U.S., and good growth globally. Since 2008 is an election year, individual sectors such as Health Care may see some volatility. But while employment is still strong, consumer confidence is low, and the slowdown in consumer spending is likely to persist as the interest rates on many adjustable-rate mortgages reset higher next year. In preparation, over the past year we have lowered the portfolio's weighting to Consumer Discretionary and increased its weighting to Industrials and companies with global exposure.

We continue to adhere to our strategy of looking for companies with high forecast earnings-growth and strong profitability that are selling at relatively reasonable valuations. While these kinds of "quality" stocks have been out of favor for the past two years, the strategy has generally added value over the long term. We also believe the market will return to focusing on fundamentals and quality now, after the turmoil of the past quarter.

Performance Comparison

Comparison of change in value of $10,000 investment.

* Note Regarding Class I Shares Total Returns: There were times during the reporting period when there were no shareholders in Class I. For purposes of reporting Average Annual Total Return, Class A performance at NAV (i.e. does not reflect deduction of the Class A front-end sales charge) is used during these periods in which there were no shareholders in Class I. For purposes of this Average Annual Total Return, the Class A performance at NAV was used during the period January 18, 2002 through June 3, 2003.

Average annual total returns in the Portfolio Statistics and the Performance Comparison line graph are with maximum load deducted -- they assume reinvestment of dividends and reflect the deduction of the Fund's Class A maximum front-end sales charge of 4.75%, or deferred sales charge, as applicable. No sales charge has been applied to the index used for comparison. However, the Lipper average does reflect the deduction of the category's average front-end sales charge. The value of an investment in Class A & C shares is plotted in the line graph. The value of an investment in another class of shares would be different. The graph and table do not reflect the deduction of taxes that a shareholder would pay on the Fund's distributions or the redemption of Fund shares. Past performance is no guarantee of future results.

Shareholder Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges and redemption fees; and (2) ongoing costs, including management fees; distribution (12b-1) fees; and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

This Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (April 1, 2007 to September 30, 2007).

Actual Expenses

The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, 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 line 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 line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual 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 the 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. Therefore, the second line 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 have been higher.

	Beginning	Ending Account	Expenses Paid
	Account Value	Value	During Period*
	4/1/07	9/30/07	4/1/07 - 9/30/07
Class A
Actual	$1,000.00	$1,067.60	$8.38
Hypothetical	$1,000.00	$1,016.96	$8.17
(5% return per year before expenses)
Class B
Actual	$1,000.00	$1,062.50	$12.95
Hypothetical	$1,000.00	$1,012.51	$12.63
(5% return per year before expenses)
Class C
Actual	$1,000.00	$1,063.10	$12.30
Hypothetical	$1,000.00	$1,013.15	$12.00
(5% return per year before expenses)
Class I
Actual	$1,000.00	$1,071.70	$4.47
Hypothetical	$1,000.00	$1,020.76	$4.36
(5% return per year before expenses)

* Expenses are equal to the Fund's annualized expense ratio of 1.62%, 2.50%, 2.38% and 0.86% for Class A, Class B, Class C, and Class I respectively, multiplied by the average account value over the period, multiplied by 183/365.

Notes to Financial Statements

Note A -- Significant Accounting Policies

General: The Calvert Capital Accumulation Fund (the "Fund"), a series of Calvert World Values Fund, Inc., is registered under the Investment Company Act of 1940 as a non-diversified, open-end management investment company. The operation of each series is accounted for separately. The Fund offers four classes of shares of capital stock. Class A shares are sold with a maximum front-end sales charge of 4.75%. Class B shares are sold without a front-end sales charge. With certain exceptions, the Fund will impose a deferred sales charge at the time of redemption, depending on how long investors have owned the shares. Class C shares are sold without a front-end sales charge. With certain exceptions, the Fund will impose a deferred sales charge on shares sold within one year of purchase. Class B and Class C shares have higher levels of expenses than Class A shares. Class I shares require a minimum account balance of $1,000,000. The $1 million minimum initial investment may be waived for certain institutional ac counts, where it is believed to be in the best interest of the Fund and its shareholders. Class I shares have no front-end or deferred sales charge and have lower levels of expenses than Class A Shares. Each class has different: (a) dividend rates, due to differences in Distribution Plan expenses and other class-specific expenses, (b) exchange privileges; and (c) class-specific voting rights.

Security 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 to value its investments wherever possible. Securities for which market quotations are available are valued at last sale price or official closing price on the primary market or exchange in which they trade. Short-term notes are stated at amortized cost, which approximates fair value. The Fund may invest in securities whose resale is subject to restrictions. Investments for which market quotations are not available or deemed not reliable are fair valued in good faith under the direction of the Board of Directors.

In determining fair value, the Board considers all relevant qualitative and quantitative information available. These factors are subject to change over time and are reviewed periodically. The values assigned to fair value investments are based on available information and do not necessarily represent amounts that might ultimately be realized. Further, because of the inherent uncertainty of valuation, those estimated values may differ significantly from the values that would have been used had a ready market for the investments existed, and the differences could be material.

At September 30, 2007, securities valued at $1,387,237, or 1.0% of net assets, were fair valued in good faith under the direction of the Board of Directors.

Repurchase Agreements: The Fund may enter into repurchase agreements with recognized financial institutions or registered broker/dealers and, in all instances, holds underlying securities with a value exceeding the total repurchase price, including accrued interest. Although risk is mitigated by the collateral, the Fund could experience a delay in recovering its value and a possible loss of income or value if the counterparty fails to perform in accordance with the terms of the agreement.

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 Fund's Statement of Net Assets.

Security Transactions and Net Investment Income: Security transactions 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. Distributions received on securities that represent a return of capital or capital gain are recorded as a reduction of cost investments and/or as a realized gain. Interest income, which includes amortization of premium and accretion of discount on debt securities, is accrued as earned. Investment income and realized and unrealized gains and losses are allocated to separate classes of shares based upon the relative net assets of each class. Expenses arising in connection with a class are charged directly to that class. Expenses common to the classes are allocated to each class in proportion to their relative net assets.

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 generally accepted accounting principles; accordingly, periodic reclassifications are made within the Fund's capital accounts to reflect income and gains available for distribution under income

tax regulations.

Estimates: The preparation of financial statements in conformity with accounting principles generally accepted in the United States 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 income and expenses during the reporting period. Actual results could differ from those estimates.

Redemption Fees: The Fund charges a 2% redemption fee on redemptions, including exchanges, made within 30 days of purchase in the same Fund (within seven days for Class I shares). The redemption fee is payable to the Class of the Fund from which the redemption is made, and is accounted for as an addition to paid-in capital. The fee is intended to discourage market-timers by ensuring that short-term trading costs are borne by the investors making the transactions and not the shareholders already in the Fund.

Expense Offset Arrangements: The Fund has an arrangement with its custodian

bank whereby the custodian's fees may be paid indirectly by credits earned on the Fund's cash on deposit with the bank. These credits are used to reduce the Fund's expenses. Such a deposit arrangement may be an alternative to overnight investments.

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

New Accounting Pronouncements: In July 2006, the Financial Accounting Standards Board (FASB) released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" -- an interpretation of FASB Statement 109 (FIN 48). FIN 48 provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken in the course of preparing the Fund's tax returns to determine whether tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax benefits of positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax expense in the current year. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. The adoption of FIN 48 is not expected to have a material impact on the Fund's financial statements.

In September 2006, the Financial Accounting Standards Board (FASB) issued Statement on Financial Accounting Standards (SFAS) No. 157, "Fair Value Measurements." This standard establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and requires additional disclosures about fair value measurements. SFAS No. 157 applies to fair value measurements already required or permitted by existing standards. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. The changes to current generally accepted accounting principles from the application of this Statement relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. As of September 30, 2007, the Fund does not believe the adoption of SFAS No. 157 will impact the financial statement amounts, however, additional disclosures may be r equired about the inputs used to develop the measurements and the effect of certain of the measurements on changes in net assets for the period.

Note B -- Related Party Transactions

Calvert Asset Management Company, Inc. (the "Advisor") is wholly-owned by Calvert Group, Ltd. ("Calvert"), which is indirectly wholly owned by UNIFI Mutual Holding Company. The Advisor provides investment advisory services and pays the salaries and fees of officers and Directors of the Fund who are employees of the Advisor or its affiliates. For its services, the Advisor receives an annual fee, payable monthly, of .65% of the Fund's average daily net assets. Under the terms of the agreement, $71,463 was payable at year end. In addition, $44,970 was payable at year end for operating expenses paid by the Advisor during September 2007.

The Advisor has contractually agreed to limit net annual fund operating expenses through January 31, 2008 for Class I. The contractual expense cap is 0.86%. For the purposes of this expense limit, operating expenses do not include interest expense, brokerage commissions, taxes, and extraordinary expenses. To the extent that any expense offset credits are earned, the Advisor's obligation under the contractual limitation may be reduced and the Advisor may benefit from the expense offset arrangement.

Calvert Administrative Services Company, an affiliate of the Advisor, provides administrative services to the Fund for an annual fee, payable monthly of .25% for Class A, Class B and Class C, and .10% for Class I shares based on their average daily net assets. Under the terms of the agreement, $26,956 was payable at year end.

Calvert Distributors, Inc., an affiliate of the Advisor, is the distributor and principal underwriter for the Fund. Distribution Plans, adopted by Class A, Class B, and Class C shares, allow the Fund to pay the Distributor for expenses and services associated with distribution of shares. The expenses paid may not exceed .35%, 1.00% and 1.00% annually of average daily net assets of Class A, Class B, and Class C, respectively. The amount actually paid by the Fund is an annualized fee, payable monthly of .35%, 1.00% and 1.00% of the Fund's average daily net assets of Class A, Class B, and Class C, respectively. Class I shares do not have Distribution Plan expenses. Under the terms of the agreement, $50,268 was payable at year end.

The Distributor received $34,154 as its portion of the commissions charged on sales of the Fund's Class A shares for the year ended September 30, 2007.

Calvert Shareholder Services, Inc. ("CSSI"), an affiliate of the Advisor, acts as shareholder servicing agent for the Fund. For its services, CSSI received a fee of $114,409 for the year ended September 30, 2007. Under the terms of the agreement, $8,409 was payable at year end. Boston Financial Data Services, Inc. is the transfer and dividend disbursing agent.

The Fund may invest in Community Investment Notes issued by the Calvert Social Investment Foundation (the "CSI Foundation"). The CSI Foundation is a 501(c)(3) non-profit organization that receives in-kind support from the Calvert Group, Ltd. and its subsidiaries. The Fund has received from the Securities and Exchange Commission an exemptive order permitting the Fund to make investments in these notes under certain conditions.

Each Director of the Fund who is not an employee of the Advisor or its affiliates receives an annual retainer of $34,000 plus a meeting fee of $2,000 for each Board meeting attended. An additional Chair support fee of $24,000 annually is paid to the Fund Chair. Additional fees of up to $10,000 annually may be paid to the Chairperson of special committees of the Board and the lead disinterested Director. Directors' fees are allocated to each of the funds served.

Note C -- Investment Activity

During the year, purchases and sales of investments, other than short-term securities, were $62,463,622 and $80,863,382, respectively.

The cost of investments owned at September 30, 2007 for federal income tax purposes was $116,738,666. Net unrealized appreciation aggregated $20,407,968, of which $26,495,759 related to appreciated securities and $6,087,791 related to depreciated securities.

As of September 30, 2007, the components of distributable earnings/(accumulated losses) on a tax basis were as follows:

Undistributed ordinary income	$420,173
Undistributed long term capital gain	1,565,077
Unrealized appreciation (depreciation)	20,407,968
	$22,393,218

The differences between the components of distributable earnings on a tax basis and the amounts reflected in the statement of net assets are primarily due to temporary book-tax differences that will reverse in a subsequent period. These book-tax differences are mainly due to wash sales.

Reclassifications, as shown in the table below, have been made to the Fund's components of net assets to reflect income and gains available for distribution (or available capital loss carryovers, as applicable) under income tax law and regulations. These reclassifications are due to permanent book-tax differences and have no impact on net assets. The primary permanent difference causing such reclassification for the Fund is the tax treatment of net operating losses.

Undistributed net investment income	$1,525,628
Accumulated net realized gain (loss)	(1,525,628)

Note D -- Line of Credit

A financing agreement is in place with all Calvert Group Funds (except for the Calvert Social Investment Fund's Balanced and Enhanced Equity Portfolios and the CVS Calvert Social Balanced Portfolio) and State Street Corporation ("SSC"). Under the agreement, SSC provides an unsecured line of credit facility, in the aggregate amount of $50 million ($25 million committed and $25 million uncommitted), accessible by the Funds for temporary or emergency purposes only. Borrowings under the committed facility bear interest at the overnight Federal Funds Rate plus .50% per annum. A commitment fee of .10% per annum is incurred on the unused portion of the committed facility, which is allocated to all participating funds. The Fund had no loans outstanding pursuant to this line of credit at September 30, 2007. For the year ended September 30, 2007, borrowings by the Fund under the Agreement were as follows:

Average Daily Balance	Weighted Average Interest Rate	Maximum Amount Borrowed	Month of Maximum Amount Borrowed
$11,868	5.89%	$3,205,030	August 2007

Explanation of Financial Tables

Schedule of Investments

The Schedule of Investments is a snapshot of all securities held in the fund at their market value, on the last day of the reporting period. Securities are listed by asset type (e.g., common stock, corporate bonds, U.S. government obligations) and may be further broken down into sub-groups and by industry classification.

Statement of Assets and Liabilities

The Statement of Assets and Liabilities is often referred to as the fund's balance sheet. It lists the value of what the fund owns, is due and owes on the last day of the reporting period. The fund's assets include the market value of securities owned, cash, receivables for securities sold and shareholder subscriptions, and receivables for dividends and interest payments that have been earned, but not yet received. The fund's liabilities include payables for securities purchased and shareholder redemptions, and expenses owed but not yet paid. The statement also reports the fund's net asset value (NAV) per share on the last day of the reporting period. The NAV is calculated by dividing the fund's net assets (assets minus liabilities) by the number of shares outstanding. This statement is accompanied by a Schedule of Investments. Alternatively, if certain conditions are met, a Statement of Net Assets may be presented in lieu of this statement and the Schedule of Investments.

Statement of Net Assets

The Statement of Net Assets provides a detailed list of the fund's holdings, including each security's market value on the last day of the reporting period. The Statement of Net Assets includes a Schedule of Investments. Other assets are added and other liabilities subtracted from the investments total to calculate the fund's net assets. Finally, net assets are divided by the outstanding shares of the fund to arrive at its share price, or Net Asset Value (NAV) per share.

At the end of the Statement of Net Assets is a table displaying the composition of the fund's net assets. Paid in Capital is the money invested by shareholders and represents the bulk of net assets. Undistributed Net Investment Income and Accumulated Net Realized Gains usually approximate the amounts the fund had available to distribute to shareholders as of the statement date. Accumulated Realized Losses will appear as negative balances. Unrealized Appreciation (Depreciation) is the difference between the market value of the fund's investments and their cost, and reflects the gains (losses) that would be realized if the fund were to sell all of its investments at their statement-date values.

Statement of Operations

The Statement of Operations summarizes the fund's investment income earned and expenses incurred in operating the fund. Investment income includes dividends earned from stocks and interest earned from interest-bearing securities in the fund. Expenses incurred in operating the fund include the advisory fee paid to the investment advisor, administrative services fee, distribution plan expenses (if applicable), transfer agent fees, shareholder servicing expenses, custodial, legal, and audit fees, and the printing and postage expenses related to shareholder reports. Expense offsets (fees paid indirectly) are also shown. Credits earned from offset arrangements are used to reduce the fund's expenses. This statement also shows net gains (losses) realized on the sale of investments and the increase or decrease in the unrealized appreciation (depreciation) on investments held during the period.

Statement of Changes in Net Assets

The Statement of Changes in Net Assets shows how the fund's total net assets changed during the two most recent reporting periods. Changes in the fund's net assets are attributable to investment operations, distributions and capital share transactions.

The Operations section of the report summarizes information detailed in the Statement of Operations. The Distribution section shows the dividend and capital gain distributions made to shareholders. The amounts shown as distributions in this section may not match the net investment income and realized gains amounts shown in the Operations section because distributions are determined on a tax basis and certain investments or transactions may be treated differently for financial statement and tax purposes. The Capital Share Transactions section shows the amount shareholders invested in the fund, either by purchasing shares or by reinvesting distributions, and the amounts redeemed. The corresponding numbers of shares issued, reinvested and redeemed are shown at the end of the report.

Financial Highlights

The Financial Highlights table provides a per-share breakdown per class of the components that affect the fund's net asset value for current and past reporting periods. The table provides total return, total distributions, expense ratios, portfolio turnover and net assets for the applicable period. Total return is a measure of a fund's performance that encompasses all elements of return: dividends, capital gain distributions and changes in net asset value. Total return is the change in value of an investment over a given period, assuming reinvestment of any dividends and capital gain distributions, expressed as a percentage of the initial investment. Total distributions include distributions from net investment income and net realized gains. Long-term gains are earned on securities held in the fund more than one year. Short-term gains, on the sale of securities held less than one year, are treated as ordinary dividend income for tax purposes. The expense ratio is a fund's cost of doing business, ex pressed as a percentage of net assets. These expenses directly reduce returns to shareholders. Portfolio turnover measures the trading activity in a fund's investment portfolio -- how often securities are bought and sold by a fund. Portfolio turnover is affected by market conditions, changes in the size of the fund, the nature of the fund's investments and the investment style of the portfolio.

Proxy Voting

The Proxy Voting Guidelines of the Calvert Funds that the Fund uses to determine how to vote proxies relating to portfolio securities are 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 Fund at 1-800-368-2745, by visiting the Calvert website at www.calvert.com; or by visiting the SEC's website at www.sec.gov.

Information regarding how the Fund voted proxies relating to portfolio securities during the most recent 12-month period ended June 30 is available on the Fund's website at www.calvert.com and on the SEC's website at www.sec.gov.

Availability of Quarterly Portfolio Holdings

The Fund files its complete schedule of portfolio holdings with the SEC for the first and third quarters of each fiscal year on Form N-Q. The Fund's Form N-Q is available on the SEC's website at www.sec.gov. The Fund's Form N-Q may be reviewed and copied at the SEC's Public Reference Room in Washington, DC;  information on the operation of the Public Reference Room may be obtained by calling 1-800-SEC-0330.

Dear Shareholder:

Over the 12 months ended September 30, 2007, the U.S. and international equity markets fluctuated dramatically, moving from a fairly steady upward climb during the first half of the period to marked volatility in the third quarter of this year. In July, turmoil from the subprime mortgage market spilled over into stock markets at home and abroad as subprime lenders and other financial institutions worldwide suffered declines and investors became increasingly risk averse.

Despite the subprime woes, the overall U.S. stock market, as measured by the Standard & Poor's 500 Index, climbed a healthy 16.44% for the 12-month period. International stock markets outpaced the U.S., demonstrating resilience despite high energy prices, inflationary pressures, and other global concerns. The Morgan Stanley Capital International (MSCI) Europe Australasia Far East (EAFE) Index, a benchmark for non-U.S. stocks, returned 25.38%, boosted in part by a weak U.S. dollar. Emerging markets, however, again outshone other regions, as many of these countries continued to enjoy growing consumer demand.

A Look at the Subprime Situation

The volatility in the global stock markets this summer was caused by the turmoil in the subprime mortgage market. Many of these mortgages were packaged into securities of varying complexity. Some of these received top credit ratings and were purchased by financial firms, including hedge funds and investment banks, around the world. When default rates for the underlying mortgages started to increase much more quickly than expected, some holders of the securities were forced to mark down their values.

A Reevaluation of Risk

The unexpected declines in value forced the liquidation of several high-profile hedge funds, hurt the stock prices of financial companies, and generally caused investors to reevaluate risk in the global stock and bond markets. While these events may seem unsettling, we view them as a normal correction in the equity and financial markets, returning to the traditionally lower prices seen for riskier assets. In recent years, investors had been irrationally paying as much for riskier stocks as for higher-quality stocks in the hopes of earning a little more return. Also, volatility in the stock market had been near historic lows. Now, in this more cautious environment, we see opportunities for larger-cap and higher-quality stocks to shine.

Calvert Conducts Climate Change Survey

In early 2007, Calvert conducted an on-line survey of shareholders and clients to help us sharpen the focus and assess the relevance of the environmental, social, and governance criteria that we use to evaluate companies for our socially responsible portfolios.

More than 1,500 Calvert shareholders responded to the survey on climate change and other environmental concerns. Of those responding, 97% said the leading reason they chose socially responsible funds was to invest in companies with good environmental practices. Also, climate change topped the list of socially responsible investors' concerns, and 90% of investors said that their unease about climate change has increased over the last five years.

Two New Funds Debut

Partially in response to these results, Calvert launched the Calvert Global Alternative Energy Fund on May 31, 2007. The Fund, which is managed by Dublin-based KBC Asset Management International Ltd., invests in a broad universe of U.S. and non-U.S. stocks that are significantly involved in the alternative energy industry. The Fund offers investors the opportunity to address the urgent issue of climate change while investing in one of the fastest-growing market sectors globally. Keep in mind, however, that this is a sector fund, which means it is likely to be volatile over time. It's important that investors in this Fund have a long-term perspective and time horizon.

In addition, Calvert launched the Calvert International Opportunities Fund, managed by London-based subadvisor F&C Management Limited, on May 31. We are pleased with the Fund's results so far, as reflected in the portfolio manager's letter. This Fund seeks long-term capital appreciation by investing in growth-oriented small-cap and mid-cap foreign stocks. Coupled with the Calvert World Values International Equity Fund, which invests in large-cap foreign stocks, the Calvert International Opportunities Fund gives Calvert investors access to the full range of market capitalizations in foreign companies.

Calvert Continues to Grow

Also during the reporting period, Calvert surpassed $15 billion in total assets under management. As we continue to grow, Calvert remains committed to striving to maximize the performance of our funds in terms of both financial returns to shareholders and returns to society as a whole.

Thank you for your continued confidence in our mutual funds, and we look forward to continuing our endeavor to meet your investment needs in the future.

Sincerely,

Barbara J. Krumsiek

Social Update
from the Calvert Social Research Department

The work of Calvert's Social Research Department and our unique investment programs continue to demonstrate Calvert's leadership in socially responsible investment practices. This Social Update highlights key initiatives and involvement for the 12-month reporting period ended September 30, 2007.

Shareholder Advocacy

Shareholder resolutions have been a key tool in enhancing shareholders' communications with the companies they invest in for more than three decades--but now that tool is in serious jeopardy as the Securities and Exchange Commission (SEC) evaluates making changes to the shareholder resolution process. As a result, Calvert Group has been playing a major role in the campaign to preserve shareholder rights this year. We have expressed our strong opposition to the SEC in formal comments on several alternative proposals. In September, Paul Hilton, Calvert Director of Advanced Equities Research, along with other members of the Social Investment Forum, spent a day lobbying members of Congress on the issue. Calvert also participated in a press event to bring public attention to this issue.

We believe the SEC's proposed alternatives would severely undermine shareholders' rights to submit resolutions that raise environmental, governance, and social issues. In fact, Calvert believes that, instead of rolling back investors' rights, the Commission ought to move in the other direction and allow shareholders to submit a wider range of resolutions. We will continue to actively work toward a favorable resolution of this issue.

The Results of This Year's Campaign

Our 2007 proxy season was our most successful one yet. We filed or co-filed an all-time high of 36 shareholder resolutions encouraging the companies in our portfolios to change their policies on issues ranging from employee diversity to climate-change reporting. Of these, 20 were withdrawn after companies agreed to make changes in these areas. Of the 11 that have been voted upon, two resolutions received more than 50% of the vote--our best showing ever. One of the resolutions was for Unisys Corp. on disclosure of political contributions and the other was for HCC Insurance Holdings on employee diversity.1 Four more resolutions received about one-third of the vote or higher, which is still a remarkably high number. For more information on the proxy votes, please visit www.calvert.com, select "Socially Responsible Investing" and click on "Shareholder Advocacy."

Political Contributions

As the 2008 elections draw near, we have increased our focus on corporate political contributions. We believe it is important for companies to ensure that political activity is conducted with integrity as part of a strong and enforceable code of conduct, and that political spending is fully disclosed to shareholders. In fact, five of the shareholder resolutions we filed this year called for companies to report all types of political contributions. One received a vote of 52% (Unisys), and three--Hewlett-Packard Co., Pfizer, and Medtronic-- were withdrawn successfully after those companies decided to make the disclosures. In one case, the resolution was withdrawn after the company was acquired.

Special Equities

A modest but important portion of certain Funds is allocated for venture capital investment in innovative companies that are developing for-profit products or services that address important social or environmental issues. Illinois-based Sword Diagnostics is one such investment. Sword's technology reduces the time for food manufacturers to detect the presence of potentially deadly listeria bacteria by one-third--so they can act to stop the contamination within hours instead of two to three days.2 In New York, Marrone Organic Innovations is tackling one of the biggest hurdles to lowering the cost and increasing the availability of organically grown food--by creating effective, natural products for pest management.3 Specifically, the company creates new products to control weeds, pests, and other plant diseases using naturally occurring microorganisms it has identified.

Sudan Divestment

Calvert Group's work toward ending the atrocities in Darfur continues. On October 3, Calvert Senior Vice President of Social Research and Policy, Bennett Freeman, delivered testimony to the U.S. Senate Committee on Banking, Housing, and Urban Affairs about how asset managers can use targeted divestment to increase economic and political pressure on the Khartoum Government in ways consistent with their fiduciary responsibilities. We also continue to lend analytical and advocacy support to the Sudan Divestment Task Force (SDTF) and the Save Darfur Coalition (SDC), with whom we formed relationships earlier this year.

Community Investments

Many of our Funds participate in Calvert's High Social Impact Investing (HSII) program, which is administered through the Calvert Social Investment Foundation. This community investment program may allocate up to 1% to 3% of Fund assets at below-market interest rates to investments that provide economic opportunity for struggling populations.4

During the reporting period, the Calvert Social Investment Foundation invested in Tides Shared Spaces, a program of the Tides nonprofit network, to help develop a nonprofit office center in New York City using a "green" architectural plan. This shared-space facility will provide stable rental rates for a number of nonprofits as well as conference center facilities and opportunities for tenant collaboration and sharing. Tides has already established a similar center in San Francisco.

As a result of the HSII program, eBay-owned MicroPlace has chosen the Calvert Foundation's Community Investment Note program as one of the first securities issuers for its new microfinance business.5 The MicroPlace Web site allows the public to invest in various institutions that provide small loans to impoverished entrepreneurs around the world. This is a major innovation--harnessing the power of the Internet to exponentially expand and revolutionize the practice of microfinance investing. You should feel proud that your investment in the Calvert Funds was instrumental in the establishment of this groundbreaking online marketplace.

As always, we appreciate your investment in Calvert mutual funds and will continue to manage your investments with an eye on both financial performance and corporate integrity.

Portfolio Management Discussion

Sophie Horsfall
of F&C Management Limited

Calvert International Opportunities Fund was launched on May 31, 2007, with F&C Management Limited as portfolio manager. The Fund seeks long-term capital appreciation by investing in growth-oriented, foreign small-cap and mid-cap stocks in both developed and emerging markets.1 We use a primarily bottom-up strategy to identify the best stocks in a sector globally. This involves conducting in-depth fundamental research to assess companies' key drivers, catalysts for growth, and risks, as well as determining what we believe to be the stock's true value.

Investment Performance

Calvert International Opportunities Fund Class A shares (at NAV*) returned 2.13% for the period since inception on May 31, 2007, outperforming the benchmark Citigroup/S&P World ex-U.S. Extended Market Index (EMI), which returned -1.32% for the period. Both sector and stock selection made positive contributions to the Fund's performance.

Investment Climate

Over the Fund's first four months, international stocks have broadly outperformed a U.S. stock market that was hampered by rising interest rates and concerns about the subprime mortgage market--which worsened in the third quarter. As a result, risk aversion rose significantly and led to a sell-off in global markets from mid-July to mid-August. Despite data indicating resilient growth outside the U.S., the correction affected most global markets, with the notable exception of China.

In response to these fears, and against a backdrop of moderating inflationary pressures in the U.S. and United Kingdom, central banks have softened their efforts to cool economic growth. In fact, the market's rally in late August was spurred by the Federal Reserve (Fed) moving to cut the discount rate for lending to member banks. Investors subsequently recovered their risk appetite and positive stock fundamentals returned to drive markets for the remainder of the period.

The softening interest-rate environment in the U.S. saw the dollar weaken against other major currencies--and fall to record lows against the euro. Concerns about inventory levels and resurfacing geopolitical tensions kept oil prices elevated for much of the period, rising above $80 a barrel in September.

Portfolio Strategy

Stock selection in Consumer Discretionary and Health Care drove the Fund's outperformance while sector weightings modestly detracted.

High oil prices fueled investment in alternative energy companies such as China-based JA Solar Holdings, a top-performing holding in the Industrials sector. However, U.K.-based plumbing distributor Wolseley suffered from the housing slump in the U.S., which represents about half of its business, mitigating the benefit from JA Solar.

Amid growing fears that a U.S. economic slowdown would dampen consumer spending, an overweighting to Consumer Discretionary hurt performance. However, this was more than offset by strong stock selection within the sector. In particular, clothing retailer Esprit Holdings benefited from improving margins and explosive sales growth, and sporting-equipment retailer China Hongxing Sports enjoyed strong domestic demand as the country revs up for the Beijing Olympics. Dutch GPS-manufacturer TomTom was the sector's top performer. Health Care firms such as Australia's CSL and advanced hearing-aid manufacturer Cochlear also performed well.

Regionally, our stock selection in North America was strong as we had low exposure to Financials stocks. Holdings in Europe and Japan also performed well, particularly Japanese educational company Benesse Corp. Emerging markets were the main regional driver of performance, as many of these countries continued to enjoy growing consumer demand, which has so far insulated them against the effects of a possible slowdown in the U.S.

A weakening U.S. dollar also helped performance during the period, adding more than four percent when the Fund's returns are converted from local currencies to U.S. dollars.

Outlook

We are selectively adding to areas where we see attractive opportunities. In particular, we believe the Japanese market is undervalued given its improving economic fundamentals, such as renewed growth, strong employment, and rising wages.

We expect to maintain significant exposure to the Consumer Staples and Health Care sectors, although we continue to avoid the mega-cap pharmaceutical companies which face weakening product pipelines, increased competition from generics, and declining growth prospects. In the Telecommunications sector, we see high growth potential in emerging markets.

Volatility in commodity prices and movements in the value of the U.S. dollar remain the biggest risks to the Fund in the short term, in our opinion. But we expect commodities and energy markets to remain strong over the longer term given the high demand and constrained supply for many materials. In fact, we believe that high oil prices and political and economic developments should continue to make alternative energy stocks attractive investments. Overall, we are very pleased with the strong start of this Fund and look forward to serving you in the year ahead.

Shareholder Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges and redemption fees; and (2) ongoing costs, including management fees; distribution (12b-1) fees; and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

This Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (inception date May 31, 2007 for Class A and Class I and inception date July 31, 2007 for Class C to September 30, 2007).

Actual Expenses

The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, 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 line 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 line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual 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 the 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. Therefore, the second line 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 have been higher.

Notes to Financial Statements

Note A -- Significant Accounting Policies

General: The Calvert International Opportunities Fund (the "Fund"), a series of Calvert World Values Fund, Inc., is registered under the Investment Company Act of 1940 as a diversified, open-end management investment company. The operation of each series is accounted for separately. The Fund began operations on May 31, 2007 and offers three classes of shares of capital stock. Class A shares are sold with a maximum front-end sales charge of 4.75%. Class C shares began operations on July 31, 2007. Class C shares are sold without a front-end sales charge. With certain exceptions, the Fund will impose a deferred sales charge on shares sold within one year of purchase. Class C shares have higher levels of expenses than Class A shares. Class I shares require a minimum account balance of $1,000,000. The $1 million minimum initial investment may be waived for certain institutional accounts, where it is believed to be in the best interest of the Fund and its shareholders. Class I shares have no front-end or defer red sales charge and have lower levels of expenses than Class A shares. Each class has different: (a) dividend rates, dute to differences in Distribution Plan expenses and other class-specific expenses, (b) exchange privileges, and (c) class-specific voting rights.

Security 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 to value its investments wherever possible. Securities for which market quotations are available are valued at last sale price or official closing price on the primary market or exchange in which they trade. Foreign securities are valued based on quotations from the principal market in which such securities are normally traded. If events occur after the close of the principal market in which foreign securities are traded, and before the Fund's net asset value is determined, that are expected to materially affect the value of those securities, then they are valued at their fair value taking these events into account. Short-term notes are stated at amortized cost, which approximates fair value. Investments for which market quotations are not availa ble or deemed not reliable are fair valued in good faith under the direction of the Board of Directors.

The Fund has retained a third party fair value pricing service to quantitatively analyze the price movement of its holdings on foreign exchanges and to automatically fair value if the variation from the prior day's closing price exceeds specified parameters.

In determining fair value, the Board considers all relevant qualitative and quantitative information available. These factors are subject to change over time and are reviewed periodically. The values assigned to fair value investments are based on available information and do not necessarily represent amounts that might ultimately be realized. Further, because of the inherent uncertainty of valuation, those estimated values may differ significantly from the values that would have been used had a ready market for the investments existed, and the differences could be material.

At September 30, 2007, no securities were fair valued in good faith under the direction of the Board of Directors.

Repurchase Agreements: The Fund may enter into repurchase agreements with recognized financial institutions or registered broker/dealers and, in all instances, holds underlying securities with a value exceeding the total repurchase price, including accrued interest. Although risk is mitigated by the collateral, the Fund could experience a delay in recovering its value and a possible loss of income or value if the counterparty fails to perform in accordance with the terms of the agreement.

Security Transactions and Net Investment Income: Security transactions 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 or, in the case of dividends on certain foreign securities, as soon as the Fund is informed of the ex-dividend date. Distributions received on securities that represent a return of capital or capital gain are recorded as a reduction of cost of investments and/or as a realized gain. Interest income, which includes amortization of premium and accretion of discount on debt securities, is accrued as earned. Withholding taxes on foreign dividends have been provided for in accordance with the Fund's understanding of the applicable country's tax rules and rates. Investment income and realized and unrealized gains and losses are allocated to separate classes of shares based upon the relative net assets of each class. Expenses arising in connection with a class are charged directly to that class. Expenses common to the classes are allocated to each class in proportion to their relative net assets.

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. The effect of changes in foreign exchange rates on securities and foreign currencies is included in the net realized and unrealized gain or loss on securities and foreign currencies.

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 generally accepted accounting principles; accordingly, periodic reclassifications are made within the Fund's capital accounts to reflect income and gains available for distribution under income tax regulations.

Estimates: The preparation of financial statements in conformity with accounting principles generally accepted in the United States 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 income and expenses during the reporting period. Actual results could differ from those estimates.

Redemption Fees: The Fund charges a 2% redemption fee on redemptions, including exchanges, made within 30 days of purchase in the same Fund (within seven days for Class I shares). The redemption fee is paid to the Class of the Fund from which the redemption is made, and is accounted for as an addition to paid-in capital. The fee is intended to discourage market-timers by ensuring that short-term trading costs are borne by the investors making the transactions and not the shareholders already in the Fund.

Expense Offset Arrangements: The Fund has an arrangement with its custodian

bank whereby the custodian's fees may be paid indirectly by credits earned on the Fund's cash on deposit with the bank. These credits are used to reduce the Fund's expenses. Such a deposit arrangement may be an alternative to overnight investments.

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

New Accounting Pronouncements: In July 2006, the Financial Accounting Standards Board (FASB) released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" -- an interpretation of FASB Statement 109 (FIN 48). FIN 48 provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken in the course of preparing the Fund's tax returns to determine whether tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax benefits of positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax expense in the current year. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Management has evaluated the application of the Interpretation to the Fund, and has determined that there is no impact resulting from the adoptio n of this Interpretation on the Fund's financial statements.

In September 2006, the Financial Accounting Standards Board (FASB) issued Statement on Financial Accounting Standards (SFAS) No. 157, "Fair Value Measurements." This standard establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and requires additional disclosures about fair value measurements. SFAS No. 157 applies to fair value measurements already required or permitted by existing standards. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. The changes to current generally accepted accounting principles from the application of this Statement relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. As of September 30, 2007, the Fund does not believe the adoption of SFAS No. 157 will impact the financial statement amounts, however, additional disclosures may be r equired about the inputs used to develop the measurements and the effect of certain of the measurements on changes in net assets for the period.

Note B -- Related Party Transactions

Calvert Asset Management Company, Inc. (the "Advisor") is wholly-owned by Calvert Group, Ltd. ("Calvert"), which is indirectly wholly owned by UNIFI Mutual Holding Company. The Advisor provides investment advisory services and pays the salaries and fees of officers and Directors of the Fund who are employees of the Advisor or its affiliates. For its services, the Advisor receives an annual fee, payable monthly, of .80% of the average daily net assets. Under the terms of the agreement, $4,811 was payable at period end. In addition, $6,962 was receivable from the Advisor for reimbursement of operating expenses paid during September 2007.

The Advisor has contractually agreed to limit net annual fund operating expenses through January 31, 2009. The contractual expense cap is 1.66% for Class A, 2.50% for Class C, and 1.20% for Class I. For the purposes of this expense limit, operating expenses do not include interest expense, brokerage commissions, taxes, and extraordinary expenses. To the extent any expense offset credits are earned, the Advisor's obligation under the contractual limitation may be reduced and the Advisor may benefit from the expense offset arrangement.

Calvert Administrative Services Company, an affiliate of the Advisor, provides administrative services to the Fund for an annual fee, payable monthly, of .35% for Class A and Class C shares and .15% for Class I shares, based on their average daily net assets. Under the terms of the agreement, $1,662 was payable at period end.

Calvert Distributors, Inc., an affiliate of the Advisor, is the distributor and principal underwriter for the Fund. Distribution Plans, adopted by Class A and Class C shares, allow the Fund to pay the Distributor for expenses and services associated with the distribution of shares. The expenses paid may not exceed .50% and 1.00% annually of the Fund's average daily net assets of Class A and Class C, respectively. The amount actually paid by the Fund is an annualized fee, payable monthly of .25% and 1.00% of the Fund's average daily net assets of Class A and Class C, respectively. Class I shares do not have Distribution Plan expenses. Under the terms of the agreement, $973 was payable at period end.

The Distributor received $4,381 as its portion of the commissions charged on sales of the Fund's Class A shares for the period ended September 30, 2007.

Calvert Shareholder Services, Inc. ("CSSI"), an affiliate of the Advisor, is the shareholder servicing agent for the Fund. For its services, CSSI received a fee of $452 for the period ended September 30, 2007. Under the terms of the agreement, $182 was payable at period end. Boston Financial Data Services, Inc. is the transfer and dividend disbursing agent.

Each Director of the Fund who is not an employee of the Advisor or its affiliates receives an annual retainer of $34,000 plus $2,000 for each Board meeting attended. An additional Chair support fee of $24,000 annually is paid to the Fund Chair. Additional fees of up to $10,000 annually may be paid to the Chairperson of special committees of the Board and the lead disinterested Director. Directors' fees are allocated to each of the funds served.

Note C -- Investment Activity

During the period, the cost of purchases and proceeds from sales of investments, other than short-term securities, were $8,103,038 and $92,746 respectively.

The cost of investments owned at September 30, 2007 for federal income tax purposes was $9,012,884. Net unrealized appreciation aggregated $255,903, of which $469,147 related to appreciated securities and $213,244 related to depreciated securities.

As of September 30, 2007, the components of distributable earnings/(accumulated losses) on a tax basis were as follows:

Unrealized appreciation (depreciation)        $255,903

Reclassifications, as shown in the table below, have been made to the Fund's components of net assets to reflect income and gain available for distribution (or available capital loss carryovers, as applicable) under income tax law and regulations. These reclassifications are due to permanent book-tax differences and have no impact on net assets. The primary permanent differences causing such reclassification for the Fund are foreign currency transactions and net operating losses.

Undistributed net investment income	($9,347)
Accumulated net realized gain (loss)	11,081
Paid-in capital	(1,734)

Note D -- Line of Credit

A financing agreement is in place with all Calvert Group Funds (except for the Calvert Social Investment Fund's Balanced and Enhanced Equity Portfolios and the CVS Social Balanced Portfolio) and State Street Corporation ("SSC"). Under the agreement, SSC provides an unsecured line of credit facility, in the aggregate amount of $50 million ($25 million committed and $25 million uncommitted), accessible by the Funds for temporary or emergency purposes only. Borrowings under the committed facility bear interest at the overnight Federal Funds Rate plus .50% per annum. A commitment fee of .10% per annum is incurred on the unused portion of the committed facility, which is allocated to all participating funds. The Fund had no borrowings under the agreement during the period ended September 30, 2007.

Explanation of Financial Tables

Schedule of Investments

The Schedule of Investments is a snapshot of all securities held in the fund at their market value, on the last day of the reporting period. Securities are listed by asset type (e.g., common stock, corporate bonds, U.S. government obligations) and may be further broken down into sub-groups and by industry classification.

Statement of Assets and Liabilities

The Statement of Assets and Liabilities is often referred to as the fund's balance sheet. It lists the value of what the fund owns, is due and owes on the last day of the reporting period. The fund's assets include the market value of securities owned, cash, receivables for securities sold and shareholder subscriptions, and receivables for dividends and interest payments that have been earned, but not yet received. The fund's liabilities include payables for securities purchased and shareholder redemptions, and expenses owed but not yet paid. The statement also reports the fund's net asset value (NAV) per share on the last day of the reporting period. The NAV is calculated by dividing the fund's net assets (assets minus liabilities) by the number of shares outstanding. This statement is accompanied by a Schedule of Investments. Alternatively, if certain conditions are met, a Statement of Net Assets may be presented in lieu of this statement and the Schedule of Investments.

Statement of Net Assets

The Statement of Net Assets provides a detailed list of the fund's holdings, including each security's market value on the last day of the reporting period. The Statement of Net Assets includes a Schedule of Investments. Other assets are added and other liabilities subtracted from the investments total to calculate the fund's net assets. Finally, net assets are divided by the outstanding shares of the fund to arrive at its share price, or Net Asset Value (NAV) per share.

At the end of the Statement of Net Assets is a table displaying the composition of the fund's net assets. Paid in Capital is the money invested by shareholders and represents the bulk of net assets. Undistributed Net Investment Income and Accumulated Net Realized Gains usually approximate the amounts the fund had available to distribute to shareholders as of the statement date. Accumulated Realized Losses will appear as negative balances. Unrealized Appreciation (Depreciation) is the difference between the market value of the fund's investments and their cost, and reflects the gains (losses) that would be realized if the fund were to sell all of its investments at their statement-date values.

Statement of Operations

The Statement of Operations summarizes the fund's investment income earned and expenses incurred in operating the fund. Investment income includes dividends earned from stocks and interest earned from interest-bearing securities in the fund. Expenses incurred in operating the fund include the advisory fee paid to the investment advisor, administrative services fees, distribution plan expenses (if applicable), transfer agent fees, shareholder servicing expenses, custodial, legal, and audit fees, and the printing and postage expenses related to shareholder reports. Expense offsets (fees paid indirectly) are also shown. Credits earned from offset arrangements are used to reduce the fund's expenses. This statement also shows net gains (losses) realized on the sale of investments and the increase or decrease in the unrealized appreciation (depreciation) on investments held during the period.

Statement of Changes in Net Assets

The Statement of Changes in Net Assets shows how the fund's total net assets changed during the two most recent reporting periods. Changes in the fund's net assets are attributable to investment operations, distributions and capital share transactions.

The Operations section of the report summarizes information detailed in the Statement of Operations. The Distribution section shows the dividend and capital gain distributions made to shareholders. The amounts shown as distributions in this section may not match the net investment income and realized gains amounts shown in the Operations section because distributions are determined on a tax basis and certain investments or transactions may be treated differently for financial statement and tax purposes. The Capital Share Transactions section shows the amount shareholders invested in the fund, either by purchasing shares or by reinvesting distributions, and the amounts redeemed. The corresponding numbers of shares issued, reinvested and redeemed are shown at the end of the report.

Financial Highlights

The Financial Highlights table provides a per-share breakdown per class of the components that affect the fund's net asset value for current and past reporting periods. The table provides total return, total distributions, expense ratios, portfolio turnover and net assets for the applicable period. Total return is a measure of a fund's performance that encompasses all elements of return: dividends, capital gain distributions and changes in net asset value. Total return is the change in value of an investment over a given period, assuming reinvestment of any dividends and capital gain distributions, expressed as a percentage of the initial investment. Total distributions include distributions from net investment income and net realized gains. Long-term gains are earned on securities held in the fund more than one year. Short-term gains, on the sale of securities held less than one year, are treated as ordinary dividend income for tax purposes. The expense ratio is a fund's cost of doing business, ex pressed as a percentage of net assets. These expenses directly reduce returns to shareholders. Portfolio turnover measures the trading activity in a fund's investment portfolio -- how often securities are bought and sold by a fund. Portfolio turnover is affected by market conditions, changes in the size of the fund, the nature of the fund's investments and the investment style of the portfolio manager.

BASIS FOR BOARD'S APPROVAL OF INVESTMENT ADVISORY CONTRACTS

At a meeting held on March 12, 2007, the Board of Directors, and by a separate vote, the disinterested Directors, voted to approve an amendment to the Investment Advisory Agreement ("Advisory Agreement") between Calvert World Values Fund, Inc. and the Advisor that would add the Fund to the Advisory Agreement and initially approve the Investment Subadvisory Agreement ("Subadvisory Agreement") between the Advisor and F&C Management Limited ("Subadvisor") with respect to the Fund.

The disinterested Directors were separately represented by independent legal counsel with respect to their consideration of the approval of the Advisory Agreement and the Subadvisory Agreement. Prior to voting, the disinterested Directors reviewed the proposed approval of the Advisory Agreement and the Subadvisory Agreement with management and also met in a private session with their counsel at which no representatives of management were present.

In evaluating the Advisory Agreement, the Board of Directors considered a variety of information relating to the Fund and the Advisor. The disinterested Directors reviewed a report prepared by the Advisor regarding various services to be provided to the Fund by the Advisor and its affiliates.

In the course of its deliberations regarding the Advisory Agreement, the Board of Directors considered the following factors, among others: the nature, extent and quality of the services to be provided by the Advisor, including the personnel that would be providing such services; the Advisor's financial condition; the level and method of computing the Fund's advisory fee; comparative fee and expense information for the Fund; the profitability of the Calvert Group of Funds to the Advisor; the direct and indirect benefits, if any, to be derived by the Advisor from its relationship with the Fund; the effect of the Fund's potential growth and size on the Fund's performance and expenses; the affiliated distributor's process for monitoring sales load breakpoints; the Advisor's compliance programs and policies; the Advisor's performance of substantially similar duties for other funds; and any possible conflicts of interest.

In considering the nature, extent and quality of the services to be provided to the Fund by the Advisor under the Advisory Agreement, the Board of Directors reviewed information provided by the Advisor relating to its operations and personnel, including, among other data, biographical information on the Advisor's investment, supervisory and professional staff and descriptions of its organizational and management structure. The Board of Directors also took into account similar information provided throughout the previous year by the Advisor as well as the Board of Directors' familiarity with the Advisor's senior management through Board of Directors' meetings, discussions and other reports. The Board of Directors discussed the Advisor's effectiveness in monitoring the performance of similarly managed funds' subadvisors and the Advisor's timeliness in responding to performance issues with respect to those funds. The Advisor's administrative capabilities, including its ability to supervise the other servi ce providers for the Fund, were also considered. The Board of Directors concluded that it was satisfied with the nature, extent and quality of services to be provided to the Fund by the Advisor under the Advisory Agreement.

In considering the Fund's fees and expenses, the Board of Directors compared the Fund's proposed fees and estimated total expense ratio with those of comparable funds. The Board of Directors noted that the Fund's estimated total expenses for its Class A shares, after estimated reimbursements, would be above the median total expenses of certain comparable funds as selected by the Advisor in its report to the Board. The Board of Directors took into account that the Advisor had contractually agreed to limit the Fund's net annual operating expenses through January 31, 2009. The Board also considered the impact of the size of the Fund on the Fund's expenses. The Board also noted that the Advisor would pay the Subadvisor's subadvisory fee out of its advisory fee. Based upon its review, the Board of Directors determined that the proposed advisory fee was reasonable in view of the services to be provided to the Fund by the Advisor and the other factors considered.

In reviewing the estimated profitability of the advisory fee to the Fund's Advisor, the Board of Directors considered the fact that affiliates would be providing shareholder servicing and administrative services to the Fund for which they would receive compensation. The Board of Directors also considered whether the Advisor had the financial wherewithal to provide a high level of services to the Fund. The Board of Directors noted that the Advisor had agreed to reimburse expenses of the Fund above a certain asset level. The Board of Directors also considered that the Advisor would likely derive benefits to its reputation and other indirect benefits from its relationship with the Fund. The Board of Directors also noted that the Advisor would pay the Subadvisor's subadvisory fees out of the advisory fees it would receive from the Fund. Based upon its review, the Board of Directors concluded that the Advisor's anticipated level of profitability from its relationship with the Fund was reasonable.

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

In approving the Advisory Agreement, the Board of Directors, including the disinterested Directors, did not identify any single factor as controlling, and each Director attributed different weight to various factors.

In evaluating the Subadvisory Agreement, the Board of Directors reviewed information provided by the Advisor and the Subadvisor relating to the Subadvisor's operations, personnel, investment philosophy, strategies and techniques. Among other information, the Advisor and the Subadvisor provided biographical information on portfolio management and other professional staff, performance information for the Subadvisor, and descriptions of the Subadvisor's investment philosophies, strategies and techniques, organizational and management structures and brokerage policies and practices.

The Board of Directors approved the Subadvisory Agreement between the Advisor and the Subadvisor based on a number of factors relating to the Subadvisor's ability to perform under the Subadvisory Agreement. In the course of its deliberations, the Board of Directors evaluated, among other factors: the nature, extent and the quality of the services to be provided by the Subadvisor; the Subadvisor's management style and long-term performance record in employing its investment strategies; the Subadvisor's current level of staffing and its overall resources; the qualifications and experience of the Subadvisor's personnel; the Subadvisor's financial condition with respect to its ability to perform the services required under the Subadvisory Agreement; the Subadvisor's compliance systems, including those related to personal investing; and any disciplinary history. Based upon its review, the Board of Directors concluded that it was satisfied with the nature, extent and quality of services to be provided to the Fund by the Subadvisor under the Subadvisory Agreement.

In considering the Subadvisor's comparable performance with similarly managed funds and non-mutual fund accounts, the Board of Directors noted the Subadvisor's long-term performance record with respect to the investment strategies that it would utilize in managing the Fund. The Board noted that the Subadvisor did not manage an account or fund directly that was comparable to the Fund. In considering the performance of the Subadvisor's products, the Board of Directors took into the account that such performance information had been presented in order to provide the Directors insight into the investment capabilities of the Subadvisor and its success within the international, socially-responsible investing space, including the Subadvisor's ability to work with social screens similar to those that would be used in managing the Fund.

In considering the cost of services to be provided by the Subadvisor and the profitability to the Subadvisor of its relationship with the Fund, the Board of Directors relied on the ability of the Advisor to negotiate the Subadvisory Agreement and the corresponding subadvisory fee at arm's length. The Board of Directors also noted that the subadvisory fees under the Subadvisory Agreement would be paid by the Advisor out of the advisory fees that the Advisor would receive under the Advisory Agreement. The Board of Directors also took into consideration that the Subadvisor contractually agreed to waive 5 basis points in subadvisory fees until the Fund reaches $100 million in assets or has been in operation for two years, whichever occurs first. Based upon its review, the Board of Directors determined that the subadvisory fee was reasonable. Because the Advisor would pay the Subadvisor's subadvisory fee and had negotiated that fee at arm's length with the Subadvisor, the costs of services to be provided b y the Subadvisor and the profitability to the Subadvisor of its relationship with the Fund were not material factors in the Board of Directors' deliberations. For similar reasons, the Board of Directors did not consider the potential economies of scale in the Subadvisor's management of the Fund to be a material factor in its consideration, although the Board of Directors noted that the subadvisory fee included breakpoints that would reduce the subadvisory fee on assets above specified asset levels.

In approving the Subadvisory Agreement, the Board of Directors, including the disinterested Directors, did not identify any single factor as controlling, and each Director attributed different weight to various factors.

Conclusions

The Board of Directors reached the following conclusions regarding the Advisory Agreement and the Subadvisory Agreement, among others: (a) the Advisor has demonstrated that it possesses the capability and resources to perform the duties required of it under the Advisory Agreement; (b) the Subadvisor is qualified to manage the Fund's assets in accordance with the Fund's investment objective and polices; (c) the Advisor and Subadvisor maintain appropriate compliance programs; (d) the Subadvisor's investment strategies are appropriate for pursuing the investment objective of the Fund; and (e) the Fund's proposed advisory and subadvisory fees are reasonable relative to those of similar funds and to the services to be provided by the Advisor and the Subadvisor. Based on its conclusions, the Board of Directors determined that approval of the Advisory Agreement and the Subadvisory Agreement would be in the interests of the Fund and its shareholders.

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.

The Audit Committee is required to pre-approve all audit and non-audit services provided to the registrant by the auditors, and to the registrant's investment advisor, and any entity controlling, controlled by, or under common control with the advisor that provides ongoing services to the registrant. In determining whether to pre-approve non-audit services, the Audit Committee considers whether the services are consistent with maintaining the independence of the auditors. The Committee may delegate its authority to pre-approve certain matters to one or more of its members. In this regard, the Committee has delegated authority to the Audit Committee Chair 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 advisor in each instance.

EX-99.CODE ETH

THE CALVERT GROUP OF FUNDS (collectively, the "Funds")
CODE OF ETHICS FOR PRINCIPAL EXECUTIVE AND PRINCIPAL ACCOUNTING OFFICERS

I.     Introduction

The Boards of Directors/Trustees of the Funds have adopted this Code of Ethics (this "Code") pursuant to Section 406 of the Sarbanes-Oxley Act applicable to the Funds' Principal Executive Officer[s] and Principal Accounting Officer[s] (the "Covered Officers") to promote:

• Honest and ethical conduct, including the ethical handling of conflicts of interest;
• Full, fair, accurate, timely and understandable disclosure;
• Compliance with applicable laws and governmental rules and regulations;
• The prompt internal reporting to an appropriate person or persons identified in the Code of violations of the Code; and
• Accountability for adherence to the Code.

II.     General Standards of Conduct

The Code embodies the commitment of the Funds to conduct their business with the highest ethical standards and in accordance with all applicable governmental laws, rules and regulations.

Each Covered Officer must:

• Act with integrity, including being honest and candid while still maintaining the confidentiality of information where required by law or the Funds' policies;
• Observe both the form and spirit of laws and governmental rules and regulations, accounting standards and the Funds' policies;
• Adhere to a high standard of business ethics; and
• Place the interests of the Funds before the Covered Officer's own personal interests.

III.     Personal Conflicts of Interest

A "personal conflict of interest" occurs when a Covered Officer's private interest improperly interferes with the interests of a Fund. In particular, a Covered Officer must never use or attempt to use his or her position with a Fund to obtain any improper personal benefit for himself or herself, for his or her family members or for any other person.

Certain conflicts of interest covered by this Code arise out of the relationships between Covered Officers and the Funds that already are subject to conflict of interest provisions in the Investment Company Act of 1940 and the Investment Advisers Act of 1940. For example, Covered Officers may not individually engage in certain transactions (such as the purchase or sale of securities or other property) with the Funds because of their status as "affiliated persons" of the Funds. Therefore, as to the existing statutory and regulatory prohibitions on individual behavior there will not be a violation of this Code unless there is a violation of such prohibition. Covered Officers must in all cases comply with applicable statutes and regulations.

As to conflicts arising from, or as a result of the contract relationship between, the Funds and the Funds' investment adviser, Calvert Asset Management Company, Inc. ("CAMCO"), of which the Covered Officers are also officers or employees, it is recognized by the Boards that, subject to CAMCO's fiduciary duties to the Funds, the Covered Officers will in the normal course of their duties (whether formally for the Funds or for CAMCO, or for both) be involved in establishing policies and implementing decisions which will have different effects on CAMCO and the Funds. The Boards recognize that the participation of the Covered Officers in such activities is inherent in the contract relationship between the Funds and CAMCO and is consistent with the expectation of the Boards of the performance by the Covered Officers of their duties as officers of the Funds.

In particular, each Covered Officer must:

• Avoid conflicts of interest wherever possible;
• Handle any actual or apparent conflict of interest ethically;
• Not use his or her personal influence or personal relationships to influence investment decisions or financial reporting by a Fund whereby the Covered Officer would benefit personally to the detriment of the Fund;
• Not cause a Fund to take action, or fail to take action, for the personal benefit of the Covered Officer rather than the benefit such Fund;
• Not use knowledge of portfolio transactions made or contemplated for a Fund to profit or cause others to profit, by the market effect of such transactions; and
• Discuss any material transaction or relationship that could reasonably be expected to give rise to a conflict of interest with the Audit Committee of the Funds' Boards of Directors/Trustees prior to proceeding with such transaction or relationship.

IV.     Disclosure

Each Covered Officer is required to be familiar, and comply, with the Funds' disclosure controls and procedures to promote full, fair, accurate, timely and understandable disclosure in the Funds' subject reports and documents filed with the SEC that is compliant with applicable laws, rules and regulations. In addition, each Covered Officer having direct or supervisory authority regarding these SEC filings or the Funds' other public communications should, to the extent appropriate within his or her area of responsibility, consult with Fund or CAMCO officers and/or employees and take other appropriate steps regarding these disclosures with the goal of making full, fair, accurate, timely and understandable disclosure.

Each Covered Officer must:

• Familiarize himself or herself with the disclosure requirements applicable to the Funds as well as the business and financial operations of the Funds; and
• Not knowingly misrepresent, or cause others to misrepresent, facts about the Funds to others, whether within or outside the Funds, including to the Funds' internal auditors, independent directors, independent auditors, and to governmental regulators and self-regulatory organizations.

V.     Compliance

It is the Funds' policy to comply with all applicable laws and governmental rules and regulations. It is the personal responsibility of each Covered Officer to adhere to the standards and restrictions imposed by those laws, rules and regulations, including those relating to affiliated transactions, accounting and auditing matters.

VI.     Reporting and Accountability

The Covered Officers should strive to identify and raise potential issues before they lead to problems, and should ask the Audit Committee for clarification about the application of this Code whenever in doubt.

Each Covered Officer must:

• Upon receipt of the Code, sign and submit to CAMCO's legal and compliance department, an acknowledgement stating that he or she has received, read, and understands the Code;
• Annually thereafter submit a form to CAMCO's legal and compliance department confirming that he or she has received, read and understands the Code and has complied with the requirements of the Code;
• Not retaliate against any employee or Covered Officer for reports of potential violations that are made in good faith; and
• Notify the Audit Committee promptly if he or she becomes aware of any violation of this Code. Failure to do so is itself a violation of this Code.

The Audit Committee is responsible for applying this Code to specific situations in which questions are presented to it and has the authority to interpret this Code in any particular situation. The Audit Committee shall take all action it considers appropriate to investigate any actual or potential violations reported to it.

The Audit Committee is responsible for granting waivers and determining sanctions, as appropriate. In addition, approvals, interpretations, or waivers sought by the Covered Officers will be considered by the Audit Committee.

VII.     Other Policies and Procedures

The Code of Ethics of the Funds and CAMCO under Rule 17j-1 of the Investment Company Act of 1940, as amended, and CAMCO's more detailed policies and procedures set forth in the CAMCO Compliance Procedures Manual are separate requirements applying to Covered Officers and others, and are not part of this Code.

VIII.     Amendments

            This Code may not be amended except in written form, which is specifically approved by a majority vote of the Funds' Boards of Directors/Trustees, including a majority of independent Directors/Trustees.

IX.     Confidentiality

            All reports and records prepared or maintained pursuant to this Code shall be considered confidential and shall be maintained and protected accordingly. Except as otherwise required by law or this Code, such matters shall not be disclosed to anyone other than the Funds, the Audit Committee and CAMCO.

X.     Internal Use

            The Code is intended solely for internal use by the Funds and does not constitute an admission, by or on behalf of the Funds, as to any fact, circumstance or legal conclusion.
