Past performance is not a guarantee or a reliable indicator of future results. Investing in the bond market is subject to certain risks including market, interest-rate, issuer, credit, and inflation risk. Investing in non-U.S. securities involves heightened risk due to currency fluctuations, and economic and political risks, which may be enhanced in emerging markets.  Mortgage and asset-backed securities may be sensitive to changes in interest rates, subject to early repayment risk, and while generally backed by a government, government-agency or private guarantor there is no assurance that the guarantor will meet its obligations. 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 Barclays Capital Mortgage-Backed Securities Index is composed of all fixed-rate securitized mortgage pools by GNMA, FNMA, and the FHLMC, including GNMA Graduated Payment Mortgages. Prior to November 1, 2008, this index was published by Lehman Brothers. It is not possible to invest directly in an unmanaged index.
