What this fund is
Objective, as filed

The Fund seeks long-term growth of capital.

Strategy, summarised

The fund invests in all securities of the S&P 500 Index in the same proportions as the Index, employing a replication strategy to track large-cap U.S. equities. Because the fund holds the full constituent set, its returns will closely mirror the Index. The fund may operate as non-diversified solely to the extent the Index itself is non-diversified, which means a single issuer's price movement could produce larger swings in fund share price than would occur in a more diversified fund.

Volatility over the last 12 months: 13.12%. Past returns are a record, not a forecast.

Jun 2026 and Jul 2026 have been filed since the trailing figures were struck, so they are not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.
