Vanguard Long Term Corporate Bond ETF (the Fund) seeks to track the performance of a market-weighted corporate bond index with a long-term, dollar-weighted average maturity. The Fund employs a passive management or indexing investment approach designed to track the performance of the Barclays Capital U.S. 10+ Year Corporate Index (the Index). This index includes the United States dollar-denominated, investment-grade, fixed-rate, taxable securities issued by industrial, utility and financial companies, with maturities greater than 10 years. 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 included in the Index. The Fund’s investment advisor is Vanguard Fixed Income Group.
