Investment Objective

The Fund seeks to match the performance of the Calvert Social Index®, which measures the investment return of large- and mid-capitalization stocks.

Investment Strategy

The Fund employs a passive management strategy designed to track, as closely as possible, the performance of the Calvert Social Index. The Fund uses a replication index method, investing in the common stock of each company in the Index in about the same proportion as represented in the Index itself. The Calvert Social Index measures the performance of those companies that meet the sustainable and socially responsible investment criteria and that are selected from the universe of approximately the 1,000 largest U.S. companies, based on total market capitalization, included in the Dow Jones Total Market Index. The Index is reconstituted once a year based on an updated list of the 1000 largest U.S. companies, and is reviewed quarterly to adjust for sustainable and responsible investment criteria and other factors.

Investment Risk

Investment in mutual funds involves risk, including possible loss of principal invested. You could lose money on your investment in the Fund or the Fund could underperform because of the following risks: the market prices of stocks held by the Fund may fall. An index fund has operating expenses; a market index does not. An index fund has operating expenses; a market index does not. Although expected to track its target index as closely as possible while satisfying its investment criteria, the Fund will not be able to match the performance of the index exactly. It is not possible to invest directly in an index. Large-cap companies may be unable to respond quickly to new competitive challenges, such as changes in technology, and also may not be able to attain the high growth rate of successful smaller companies, especially during periods of economic expansion.

Standard Deviation is a measure of a fund's risk. A standard deviation of 1 means a fund can be expected to produce an annual return that is +/-1% of its average annual return 66% of the time.
Alpha is a measure of the difference between a fund's actual returns and its expected performance, given its level of risk as measured by beta.
Beta is a measure of portfolio risk relative to the market or benchmark. A portfolio beta of 1.0 indicates a risk level equal to that of the fund's benchmark.
Excess Return is return in excess of the risk-free rate or in excess of a benchmark.
R Squared is a statistical measure that represents the percentage of a fund's movements that can be explained by movements in its benchmark index.
Tracking Error is the difference in the return earned by a portfolio and the return earned by the benchmark against which the portfolio is constructed.
Information Ratio is a measure of the consistency of excess return of a mutual fund as compared to its benchmark.
Sharpe Ratio is used to measure risk-adjusted performance. It is calculated by using standard deviation and return in excess of the benchmark to determine reward per unit of risk.
