Vanguard Intermediate-Term Treasury Index Fund ETF Shares

The investment seeks to track the performance of a market-weighted Treasury index with an intermediate-term dollar-weighted average maturity. The fund employs an indexing investment approach designed to track the performance of the Bloomberg Barclays U.S. Treasury 3-10 Year Bond Index. This index includes fixed income securities issued by the U.S. Treasury (not including inflation-protected bonds), with maturities between 3 and 10 years. At least 80% of the fund's assets will be invested in bonds included in the index.
