Vanguard Long-Term Treasury Idx Admiral

This fund employs an indexing investment approach designed to track the performance of the Bloomberg U.S. Long Treasury Bond Index. This Index includes fixed income securities issued by the U.S. Treasury (not including inflation protected bonds), with maturities greater than 10 years. Because long-term bonds tend to be very sensitive to interest-rate changes, one of the fund’s key risks is that increases in interest rates may reduce the price of the bonds in the portfolio, which would reduce the fund’s share price. Investors who are looking for a fund that seeks to provide interest income and are able to tolerate significant interest rate risk may wish to consider this fund.
