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.

The performance data quoted represents past performance, which does not guarantee future results. The investment return and principal value of an investment will fluctuate so that an investor’s shares, when redeemed, may be worth more or less than their original cost. Current performance may be higher or lower than the performance data quoted. Index reflects no deductions for fees or expenses. An investor cannot invest directly in an index. Visit www.calvert.com to obtain performance data current to the most recent month-end. Returns for periods of less than one year are not annualized.

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 held by the Fund may fall; individual investments of the Fund may not perform as expected; and/or the Fund’s portfolio management practices may not 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. High-yield, high risk bonds, which are rated below investment grade, can involve a substantial risk of loss because they have a greater risk of issuer default and are subject to greater price volatility than investment grade bonds and may be illiquid. 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 non-diversified and may be more volatile than a diversified fund.
