What this fund is
Objective, as filed

The fund seeks capital growth.

Strategy, summarised

The fund invests in stocks of companies across at least three developed countries outside the United States, with possible exposure to emerging markets, selecting securities based on analysis of individual company fundamentals rather than macroeconomic forecasts. The portfolio managers seek companies whose earnings, revenues, or key business metrics are accelerating. Because returns depend on the portfolio managers' security selection decisions, fund performance may diverge from broad market returns.
