Vanguard Intermediate-Term Bond ETF (BIV) Exchange: NYSE ARCA

The Fund employs an indexing investment approach designed to track the performance of the Bloomberg Barclays U.S. 5–10 Year Government/Credit Float Adjusted Index. This Index includes all medium and larger issues of U.S. government, investment-grade corporate, and investment-grade international dollar-denominated bonds that have maturities between 5 and 10 years and are publicly issued. The Fund invests by sampling the Index, meaning that it holds a range of securities that, in the aggregate, approximates the full Index in terms of key risk factors and other characteristics. All of the Fund's investments will be selected through the sampling process, and at least 80% of the Fund's assets will be invested in bonds held in the Index. The Fund maintains a dollar-weighted average maturity consistent with that of the Index. As of December 31, 2019, the dollar-weighted average maturity of the Index was 7.1 years. The Fund also maintains an average duration consistent with that of the Index. As of December 31, 2019, the average duration of the Index was 6.3 years.
