Lack of liquidity in an ETF could result in its value being more volatile than the underlying portfolio of securities. Sector ETFs are subject to sector risks and non-diversification risks, which may result in greater price fluctuations than the overall market. Because the fund invests in ETFs, it indirectly bears its proportionate share of the operating expenses of the underlying funds. Indirectly, the fund is subject to all risks associated with the underlying ETFs.
The guarantee on U.S. government securities applies only to the underlying securities of the Fund's portfolio, and not to the value of the Fund's shares.
The Fund may invest in high yield bonds, which may be subject to greater credit and market risks.
The principal on mortgage- or asset-backed securities may normally be prepaid at any time, which will reduce the yield and market value of these securities.
Because the Fund holds a limited number of securities, it will be impacted by each security's performance more than a Fund with a larger number of holdings.
As interest rates rise, existing bond prices fall and can cause the value of an investment in the Fund to decline. Changes in interest rates will affect the value of longer-term fixed income securities more than shorter-term securities.
