Mutual fund investing involves risk; Principal loss is possible. Investments in debt securities typically decrease in value when interest rates rise. This risk is usually greater for longer-term debt securities. Investments in lower-rated and non-rated securities present a greater risk of loss to principal and interest than higher-rated securities. Investments in Asset-Backed and Mortgage-Backed securities include additional risks that investors should be aware of including credit risk, prepayment risk, possible illiquidity and default, as well as increase susceptibility to adverse economic developments. Investments in foreign securities may involve political, economic and currency risks, greater volatility and differences in accounting methods. These risks are greater for investments in emerging markets. In order to achieve its investment objectives, the Core Fixed Income Fund may use certain types of investment derivatives. Derivatives involve risks different from, and in certain cases, greater than the risks presented by more traditional investments. Derivatives may involve certain costs and risks such as liquidity, interest rate, market, credit, management and the risk that a position could not be closed when most advantageous. Investing in derivatives could lose more than the amount invested. The Fund may also invest in securities related to real estate, which may decline in value as a result of factors affecting the real estate industry.  The Fund may use leverage which may cause the effect of an increase or decrease in the value of the portfolio securities to be magnified and the Fund to be more volatile than if leverage was not used.
