Investment objective & strategy

As of March 30, 2026 · prospectus

Objective. The fund seeks capital growth.

Strategy. The funds assets will be invested primarily in equity securities of companies that are small- to medium-sized at the time of purchase and are located in foreign developed countries. Under normal market conditions, the fund will invest at least 80% of its net assets in companies that are small- to medium-sized. The portfolio managers consider small to medium companies to be those that have a market capitalization not greater than that of the largest company in the MSCI EAFE SMID Cap Index. Though market capitalization will change from time to time, as of January 31, 2026, the total market capitalization of the largest company in the MSCI EAFE SMID Cap Index was approximately $39.1 billion.

Though market capitalization will change from time to time, as of January 31, 2026, the total market capitalization of the largest company in the MSCI EAFE SMID Cap Index was approximately $39.1 billion. The portfolio managers look for stocks of companies they believe will increase in value over time, using an investment strategy developed by the funds investment advisor. In implementing this strategy, the portfolio managers make their investment decisions based primarily on their analysis of individual companies, rather than on broad economic forecasts. Management of the fund is based on the belief that, over the long term, stock price movements follow growth in earnings, revenues and/or cash flow. The portfolio managers use a variety of analytical research tools and techniques to help them make decisions about buying or holding stocks of companies that meet their investment criteria and selling the stocks of companies that do not. Under normal market conditions, the funds portfolio managers seek securities of companies whose earnings, revenues or key business fundamentals are not only growing, but growing at an accelerating pace. The fund may engage in active and frequent trading of portfolio securities to achieve its principal investment strategies. This may cause higher transaction costs and may affect performance. It may also result in the realization and distribution of capital gains.
