Top 10 Equity Holdings

Investment Objective

The Fund seeks to maximize income, to the extent consistent with preservation of capital, primarily through investment in debt securities issued or guaranteed by the U.S. government, its agencies or instrumentalities.

Investment Strategy

Under normal circumstances, the Fund will invest at least 80% of its net assets in (i) debt securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities ("U.S. Government Securities"), (ii) repurchase agreements collateralized by U.S. Government Securities and (iii) incidental to those investments, futures contracts that are related to U.S. Government Securities. The Fund may also invest in corporate debt securities, trust preferred securities, taxable municipal securities, asset-backed securities, including commercial mortgage-backed securities, and repurchase agreements. The Fund uses an active strategy, seeking relative value to earn incremental income. There is no limit on the Fund's average maturity. The Fund seeks to avoid investing in tobacco companies.

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 bonds may fall; individual bonds in the Fund may not perform as expected; and/or the Fund’s portfolio management practices may not achieve the desired result. Bond funds are subject to interest rate risk and credit risk. When interest rates rise, the value of fixed-income securities will generally fall. In addition, the credit quality of the securities may deteriorate, which could lead to default or bankruptcy of the issuer where the issuer becomes unable to pay its obligations when due. An active trading style can result in higher turnover (exceeding 100%), may translate to higher transaction costs, may increase your tax liability, and may affect Fund performance. The Fund is nondiversified and may be more volatile than a diversified fund.

Important Disclosure

Holdings are subject to change.

The Fund seeks to avoid investing in companies classified under the tobacco industry sector of the Barclays Global Aggregate Index, the Barclays U.S. High Yield Index or the Barclays Global Emerging Market Index; or, in the opinion of the Fund's Advisor, any similar securities in the Barclays Municipal Index.

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.

Important Disclosure

Performance results for Class I shares of Calvert Government Fund prior to April 30, 2011 (the Class I shares' inception date) reflect the performance of Class A shares at net asset value. Actual Class I share performance would have been higher than Class A share performance because Class I, unlike Class A, has no Rule 12b-1 fees.

Ratings are determined by using S&P, Moody's and Fitch rating services, whose rating categories are reflected above respectively. The letter ratings generally range from AAA (judged to be of the highest quality, with minimal credit risk) to D (the lowest rated class of bonds, typically in default with respect to timely payment of principal or interest). Bonds rated by all three services are assigned the median rating; if a bond is rated by only two agencies, it is assigned the lowest rating; if it is only rated by one agency, it is assigned that rating. Government securities may be rated lower than AAA/Aaa/AAA or may not be rated, and may include foreign government securities. If a bond is not rated by any of the aforementioned rating services, it appears in the "Not Rated" category. Ratings are subject to change.
