Fund profile

As filed in the prospectus · 2026 Q1

The investment objective of the U.S. Core Equity 1 Portfolio (the Portfolio) is to achieve long-term capital appreciation.

Strategy · summarised

The fund invests in a broad portfolio of U.S. equities weighted by market capitalization, with moderately increased exposure to smaller-cap, lower-priced, and higher-profitability companies relative to their weight in the overall U.S. market. The manager adjusts these tilts and may also increase or reduce positions based on shorter-term factors including price momentum and investment characteristics. Because the fund's holdings and their weights diverge from market-cap weighting, performance will differ from a broad U.S. equity index.

These positions come to 105.06% of the fund's net assets. This counts only what the fund reported holding — the holdings disclosure covers assets, not liabilities such as borrowings — so it is not expected to reconcile to 100%.

Derivatives are shown at market value, not notional exposure.
