Fund profile

As filed in the prospectus · 2026 Q1

The funds investment objective is to seek total return.

Strategy · summarised

The fund invests at least 80% of assets in securities of utilities companies—those engaged in energy generation and distribution, water services, or telecommunications—selected through fundamental analysis of individual issuers. The fund may hold a significant percentage of assets in a single issuer or a small number of issuers, concentrating risk accordingly. The fund invests in both U.S. and foreign securities, including emerging markets, and may hold both equity and debt instruments.

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.
