|Vanguard Intermediate-Term Bond ETF|
|The investment seeks the performance of a market-weighted bond index with an intermediate-term dollar-weighted average maturity.
The fund employs an indexing investment approach designed to track the performance of the 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. 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.|
