Fund profile

As filed in the prospectus · 2025 Q3

The Fund seeks to provide investment results approximating the aggregate price and dividend performance of the securities included in the S&P 500 Index (the Index).

Strategy · summarised

The fund tracks the S&P 500 Index using a passive indexing approach, holding substantially all securities in the index in approximately the same weightings, though it may use optimization to minimize tracking error and manage transaction costs when full replication is impracticable. Because the fund may not hold every security in the index or in identical proportions, its quarterly performance may diverge from the index. The fund's information technology sector exposure exceeds 15% of assets, reflecting the index's own concentration.

May 2026 and Jun 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.
