About VINIX

This fund endeavors to mirror the investment performance of the S&P 500 Index, which serves as a gauge for the returns of substantial U.S. corporations. It adopts a passive, full-replication strategy, providing a convenient means to align with the market movements of a significant portion of the country's premier companies. For three-quarters of its total assets, the fund is subject to specific investment rules: it is barred from purchasing over 10% of any single entity's outstanding voting shares, and it cannot allocate more than 5% of its total assets to the securities of any one issuer. An exemption to these rules applies only if essential for precisely reflecting the makeup of its benchmark index. Importantly, these limitations do not pertain to debt instruments issued by the U.S. government or its associated bodies.
