There are risks associated with an investment in a bond fund, including credit risk, interest rate risk, and prepayment and extension risk. See the Fund's prospectus for information on these and other risks associated with the Fund. In general, bond prices rise when interest rates fall and vice versa. This effect is usually more pronounced for longer-term securities.

Income from tax-exempt funds may be subject to state and local taxes and a portion of income may be subject to the federal and/or state alternative minimum tax for certain investors. Federal and state income tax rules will apply to any capital gains distribution. Tax-exempt interest is subject to tax reporting to both individuals and the IRS. Reportable interest is subject to backup withholding (28% in 2007) if a tax payer has failed to certify their taxpayer identification number, or if the IRS requires backup withholding.

The Floating Rate Fund invests primarily in floating rate loans, the market value of which may fluctuate, sometimes rapidly and unpredictably. The principal risks of investing in the fund include liquidity risk, interest rate risk, credit risk, counterparty risk, highly leveraged transactions risk, derivatives risk, confidential information access risk, and impairment of collateral risk. Generally, when interest rates rise, the prices of fixed income securities fall, however, securities or loans with floating interest rates can be less sensitive to interest rate changes, but they may decline in value if their interest rates do not rise as much as interest rates in general. Limited liquidity may affect the ability of the fund to purchase or sell floating rate loans and may have a negative impact on fund performance. The floating rate loans and securities in which the fund invests generally are lower-rated (non-investment grade) and are more likely to experience a default, which results in more volatile prices and more risk to principal and income than investment grade loans or securities. See the Fund's prospectus for information on these and other risks associated with the Fund.
