This ETF's primary objective is to replicate the performance of the CRSP US Total Market Index. It holds a broadly diversified equity portfolio, encompassing companies of all market capitalizations—large, medium, and small—and balanced across both growth and value investment approaches. Management follows a passive strategy, often employing an index-sampling technique, and the portfolio typically holds minimal cash, maintaining full investment in its assets. The fund's modest operating costs help ensure its net performance closely aligns with the index by minimizing tracking error. A significant portion (75%) of the fund's assets is subject to certain investment constraints. Specifically, it generally cannot acquire more than 10% of any single company's outstanding voting shares, nor can it hold more than 5% of its total assets in any one issuer's securities. However, these concentration limits may be exceeded if necessary to accurately reflect the composition of its benchmark index. Importantly, these restrictions do not apply to investments in U.S. government debt or securities issued by its agencies.
