INVESTMENT OBJECTIVE

The Fund seeks to provide long-term capital appreciation primarily through investment in small company U.S. common stocks that are trading at prices below what are believed to be their intrinsic value, and which satisfy the Fund's investment criteria, including financial, sustainability and social responsibility factors. This objective may be changed by the Fund's Board of Directors without shareholder approval.

FEES AND EXPENSES OF THE FUND

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Calvert non-money market mutual funds. More information about these and other discounts is available from your financial professional and under "Choosing a Share Class" on page 87 and "Reduced Sales Charges" on page 90 of the Fund's Prospectus, and under "Method of Distribution" on page 45 of the Fund's Statement of Additional Information ("SAI").

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that:

• you invest $10,000 in the Fund for the time periods indicated and then either sell or hold your shares at the end of those periods;
• your investment has a 5% return each year;
• the Fund's operating expenses remain the same; and
• any Calvert expense limitation is in effect for year one.

Although your actual costs may be higher or lower, under these assumptions your costs would be:

Number of Years Investment is Held	Class A	Class C
		Sold	Held
1	$639	$372	$272
3	$1,062	$1,027	$1,027
5	$1,510	$1,803	$1,803
10	$2,751	$3,836	$3,836

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities ("turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the "Example", affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 61% of its portfolio's average value.

INVESTMENTS, RISKS AND PERFORMANCE

Principal Investment Strategies

The Fund offers opportunities for long-term capital appreciation with a moderate degree of risk through a mix of smaller company stocks that meet the Fund's investment criteria, including financial, sustainability and social responsibility factors. The Fund normally invests at least 80% of its net assets, including borrowings for investment purposes, in common stocks of small companies. The Fund will provide shareholders with at least 60 days' notice before changing this 80% policy. Calvert quantifies small companies as having a market capitalization of $3 billion or less at the time of initial purchase.

The Fund seeks to identify common stocks of undervalued companies with long-term growth potential. The Fund may also invest up to 25% of its net assets in foreign securities.

Sustainable and Socially Responsible Investing. The Fund seeks to invest in companies and other enterprises that demonstrate positive environmental, social and governance performance as they address corporate responsibility and sustainability challenges. Calvert believes that there are long-term benefits in an investment philosophy that attaches material weight to the environment, workplace relations, human rights, Indigenous Peoples' rights, community relations, product safety and impact, and corporate governance and business ethics. Calvert also believes that managing risks and opportunities related to these issues can contribute positively to company performance as well as to investment performance over time. The Fund has sustainable and socially responsible investment criteria that reflect specific types of companies in which the Fund seeks to invest and seeks to avoid investing.

Investments are first selected for financial soundness and then evaluated according to the Fund's sustainable and socially responsible investment criteria. Investments must be consistent with the Fund's current investment criteria, including financial, sustainability and social responsibility factors, the application of which is in the economic interest of the Fund and its shareholders.

Principal Risks

You could lose money on your investment in the Fund, or the Fund could underperform, because of the risks described below. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Management Risk. Individual stocks in the Fund may not perform as expected, and the Fund's portfolio management practices may not achieve the desired result.

Stock Market Risk. The stock market may fall in value, causing prices of stocks held by the Fund to fall.

Common Stock Risk. Although common stocks have a history of long-term growth in value, their prices fluctuate based on changes in a company's financial condition, on overall market and economic conditions, and on investors' perception of a company's well-being.

Small-Cap Company Risk. Prices of small-cap stocks can be more volatile than those of larger, more established companies. Small-cap companies are more likely to have more limited product lines, fewer capital resources and less depth of management than larger companies.

Value Company Risk. Value stocks may perform differently from the market as a whole, which may not recognize a security's intrinsic value for a long time. The value-oriented investing approach may fall out of favor with investors from time to time, during which the Fund may underperform other funds using different investment approaches.

Valuation Risk. A stock judged to be undervalued by the Fund's Subadvisor may actually be appropriately priced, and it may not appreciate as anticipated.

Foreign Securities Risk. Investing in foreign securities involves additional risks relating to political, social, and economic developments abroad. Other risks result from differences between regulations that apply to U.S. and foreign issuers and markets, and the potential for foreign markets to be less liquid and more volatile than U.S. markets.

Foreign Currency Risk. Securities that trade or are denominated in currencies other than the U.S. dollar may be adversely affected by fluctuations in currency exchange rates. When the U.S. dollar strengthens relative to a foreign currency, the U.S. dollar value of an investment denominated in that currency will typically fall.

Performance

The following bar chart and table show the Fund's annual returns and its long-term performance, which give some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Class A shares has varied from year to year. The table compares the Fund's performance over time with that of an index and an average.

The Fund's past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future. For updated performance information, visit www.calvert.com.

The return for the Fund's other Class of shares will differ from the Class A returns shown in the bar chart, depending upon the expenses of that Class. The bar chart does not reflect any sales charge that you may be required to pay upon purchase or redemption of the Fund's shares. Any sales charge will reduce your return.

Year-by-Year Total Return (Class A at NAV)

Best Quarter (of periods shown)	Q2 '09	16.70%
Worst Quarter (of periods shown)	Q4 '08	-23.11%

The average total return table shows the Fund's returns with the maximum sales charge deducted, and no sales charge has been applied to the indices used for comparison in the table.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates, and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown. The after-tax returns shown are not relevant to you if you hold your Fund shares through a tax-deferred arrangement such as a 401(k) plan or individual retirement account. The return after taxes on distributions and sale of Fund shares may be higher than the return before taxes because the calculation assumes that shareholders receive a tax benefit for capital losses incurred on the sale of their shares. After-tax returns are shown only for Class A shares; after-tax returns for other Classes will vary.

Average Annual Total Returns (as of 12-31-09) (with maximum sales charge deducted)	1 year	5 years	Since Inception (10/1/04)
Class A:
Return before taxes	14.99%	-3.43%	-1.55%
