Overview

Fund Management

Calvert Asset Management Company, Inc.

Investment Objectives

The Fund seeks to earn the highest level of interest income, exempt from federal income taxes, as is consistent with prudent investment management, preservation of capital, and the quality and maturity characteristics of the Fund. 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 decline; the individual bonds in the Fund may not perform as well as expected; and/or the Fund’s portfolio management practices may not work to achieve their 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.The prices of long-term bonds are more sensitive to changes in interest rates than the prices of short-term bonds. Therefore, in general, long-term bonds have more interest rate risk than short-term bonds. The Fund is nondiversified and compared to other funds, may invest more of its assets in a smaller number of issuers, so that gains and losses on the bonds of a single issuer may have more impact on the Fund. Some income may be subject to state and local taxes and to the federal alternative minimum tax.

Investment Strategy

Under normal market conditions, at least 80% of the income from the Fund will be exempt from federal income tax. The Fund typically invests at least 65% of its net assets in investment grade debt securities.The Fund may invest in a variety of tax-exempt obligations including tax-supported debt, various types of revenue debt, special tax obligations, qualified private activity bonds, municipal leases, and certificates of participation in such investments. The Advisor looks for securities with strong credit quality that are attractively priced in various maturity ranges. There is no limit on the Fund’s average portfolio maturity.

Important Disclosure

Prior to July 13, 2009, the Calvert Tax-Free Bond Fund emphasized investments in long-term fixed income securities and the returns shown above are the result of that investment management strategy. At a shareholder meeting held on July 13, 2009, the Fund's "Principal Investment Strategies" were amended to permit the Fund's portfolio manager to manage the Fund as a flexible duration fund without any upper or lower limit on the Fund's average maturity or average duration. The Fund's performance after July 13, 2009 reflects the Fund's new investment management strategy, which will cause the Fund to have, at times, a significantly shorter weighted average maturity and effective duration than it did prior to July 13, 2009. Past performance is no guarantee of future results.
