Fund profile

As filed in the prospectus · 2026 Q1

The investment objective of the U.S. Small Cap Portfolio (the Portfolio) is to achieve long-term capital appreciation.

Strategy · summarised

The fund invests in a broad portfolio of U.S. small-cap companies, defined as those in the lowest 10% of market capitalization or below the 1,000th largest U.S. company. The manager weights holdings by market capitalization but may overweight or underweight individual stocks based on relative price, profitability, price momentum, and other investment characteristics, and may use futures to adjust equity exposure around cash flows. Because holdings and their weights shift with the manager's assessments of these factors, the fund's composition and returns will diverge from a static small-cap market-weight benchmark.

These positions come to 118.37% 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.

Share of the fund’s equity (by value) in companies whose trailing five-year revenue — or net-income — growth ranks in the top 25% of U.S. public companies. Foreign and newly-listed holdings are excluded, so the figure covers only part of the book. From SEC filings — not investment advice. How we measure this.
