New Target Indexes

Effective immediately, Vanguard Value Index Fund and Vanguard Growth Index Fund have begun tracking new target indexes, as previously approved by the Funds’ board of trustees. The board believes that the new indexes, listed below, are well-constructed and offer comprehensive coverage of the Funds’ respective market segments. In addition, Vanguard’s agreement with the new index provider may result in considerable savings to shareholders over time in the form of lower expense ratios.

Vanguard Fund Previous Target Index New Target Index
  MSCI US Prime Market CRSP US Large Cap
Value Index Fund Value Index Value Index
  MSCI US Prime Market CRSP US Large Cap
Growth Index Fund Growth Index Growth Index

 

Each new index measures the same market segment as the corresponding previous index, so the investment objectives and risks described in each Fund’s current prospectus will not change. A Fund’s new target index could provide different investment returns (either lower or higher) or different levels of volatility from those of the previous index.


 

Prospectus and Summary Prospectus Text Changes for Vanguard Value Index Fund

The paragraph under “Primary Investment Strategies” is replaced with the following:

The Fund employs an indexing investment approach designed to track the performance of the CRSP US Large Cap Value Index, a broadly diversified index predominantly made up of value stocks of large U.S. companies. The Fund attempts to replicate the target index by investing all, or substantially all, of its assets in the stocks that make up the Index, holding each stock in approximately the same proportion as its weighting in the Index.

The paragraph under “Annual Total Returns” is replaced with the following:

The following bar chart and table are intended to help you understand the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Signal Shares has varied from one calendar year to another over the periods shown. The table shows how the average annual total returns compare with those of a relevant market index, which has investment characteristics similar to those of the Fund. Keep in mind that the Fund’s past performance does not indicate how the Fund will perform in the future.
