Vanguard Institutional Total Stock Market Index Fund Institutional Shares 

The Vanguard Institutional Total Stock Market Index Fund's primary objective is to mirror the performance of the CRSP US Total Market Index. It achieves this by investing in a diverse array of U.S. equities, covering large, mid-sized, and small companies, and balancing both growth and value investment philosophies. The fund employs a passive management approach, utilizing index sampling techniques. Regarding 75% of its total assets, the fund typically refrains from purchasing more than 10% of any issuer's outstanding voting securities or investing over 5% of its total assets in a single issuer. These specific limitations, however, can be overridden if essential for approximating the composition of its target index. Furthermore, these restrictions do not apply to investments in obligations issued by the U.S. government or its agencies and instrumentalities.
