Fund profile

As filed in the prospectus · 2025 Q4

The Funds investment objective is total return through growth of capital and current income.

Strategy · summarised

The fund invests in all securities of the S&P 500 Index in proportion to their weightings, seeking to track the index's investment results before fees and expenses. The fund is currently non-diversified, meaning a small number of large-cap constituents may represent a substantial portion of assets. The fund uses futures contracts to manage cash balances and maintain index exposure.

Cumulative return· Jun 2023 – Apr 2026
