Vanguard Institutional Total Stock Market Index Fund Institutional Plus Shares 

This fund aims to closely mirror the investment performance of the CRSP US Total Market Index. It achieves this by holding a diverse portfolio of U.S. stocks, spanning companies of all market capitalizations—large, mid, and small—and across both growth-oriented and value-oriented investment approaches. The fund is managed passively, utilizing an index sampling technique instead of active stock selection. For at least 75% of its total assets, the fund adheres to specific concentration limits: it generally avoids acquiring more than 10% of any single company's outstanding voting shares, and it typically refrains from investing over 5% of its entire portfolio in the securities of one issuer. However, these limitations may be overridden if necessary to accurately replicate the composition of its benchmark index. It's also important to note that these investment restrictions do not apply to obligations issued by the U.S. government or its associated agencies and instrumentalities.
