About VIIIX

This fund aims to mirror the investment performance of the S&P 500 Index, which serves as a benchmark for large-capitalization U.S. stocks. It achieves this objective through a non-active, complete portfolio duplication strategy. The fund provides an accessible avenue for investors to obtain exposure to a substantial portion of the nation's premier companies. For 75% of its total assets, the fund is generally precluded from acquiring more than 10% of the voting stock of any single entity or allocating over 5% of its assets to the securities of one issuer. Nevertheless, these concentration limits can be overridden if necessary to closely match the structure of its benchmark index. It's important to note that these specific restrictions do not apply to debt obligations issued by the U.S. government or its various agencies and instrumentalities.
