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.
Credit risk refers to the possibility that an issuer of a security will not be able to make principal and interest payments in a timely manner.

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.
