What this fund is
Objective, as filed

The fund seeks capital growth.

Strategy, summarised

The fund invests at least 80% of its net assets in equity securities of companies located in emerging market countries, generally focusing on those in the MSCI Emerging Markets Index, and seeks stocks whose earnings, revenues, or business fundamentals are growing at an accelerating pace. The portfolio managers base decisions on analysis of individual companies rather than economic forecasts, considering factors such as headquarters location, principal operations, revenue sources, and trading market to determine country classification. Because the fund's returns depend on the portfolio managers' stock selections, performance will diverge from any index benchmark.
