The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those periods and that you earn a 5% return each year. The example also assumes that the fund’s operating expenses remain the same, except that it reflects the rate and duration of any fee waivers noted in the table above. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 129 400 692 1522 108 338 585 1294 93 291 504 1120 720 1025 1352 2272 230 707 1211 2403 179 555 955 2071 108 338 585 1294 93 291 504 1120 1 3 6 13 Portfolio Turnover <div style="margin-bottom:9pt;margin-top:3pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">The fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund’s performance.

The example also assumes that the fund’s operating expenses remain the same, except that it reflects the rate and duration of any fee waivers noted in the table above.

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund’s performance. During the most recent fiscal year, the fund’s portfolio turnover rate was 90% of the average value of its portfolio.</span></div> 0.90 Principal Investment Strategies The fund invests primarily in securities of companies located in at least three developed countries world-wide (excluding the United States). The fund may also invest in emerging market countries. The fund generally invests in common stock and other equity securities that are denominated in foreign currencies. The portfolio managers look for stocks of companies they believe will increase in value over time, using an investment strategy developed by the fund’s 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 fund’s 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 normally invests in a relatively limited number of companies, generally 35–50. <span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:700;line-height:120%;padding-left:5.5pt">Foreign Risk</span><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%"> – Foreign securities are generally riskier than U.S. securities. Political events (such as civil unrest, national elections and imposition of exchange controls), social and economic events (such as labor strikes and rising inflation), natural disasters and public health emergencies occurring in a country where the fund invests could cause the fund’s investments in that country to experience gains or losses. Securities of foreign issuers may be less liquid, more volatile and harder to value than U.S. securities.</span> <span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:700;line-height:120%;padding-left:5.5pt">Focused Portfolio Risk</span><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%"> – Investing in a limited number of companies carries more risk because changes in the value of a single company may have a more significant effect, either negative or positive on the fund’s value.</span> <span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:700;line-height:120%;padding-left:5.5pt">Currency Risk</span><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%"> – The fund could experience gains or losses based solely on changes in the exchange rate between foreign currencies and the U.S. dollar.</span> <span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:700;line-height:120%;padding-left:5.5pt">Emerging Markets Risk</span><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%"> – Investing in emerging market countries generally is riskier than investing in foreign developed countries.

The portfolio managers look for stocks of companies they believe will increase in value over time, using an investment strategy developed by the fund’s investment advisor. In implementing this strategy, the portfolio managers make their investment decisions based primarily on their analysis of individual companies, rather than on 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 fund’s portfolio managers seek securities of companies whose earnings, revenues or key business fundamentals are not only growing, but growing at an accelerating pace.</span></div><div style="margin-bottom:3pt;margin-top:3pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">The fund may engage in active and frequent trading of portfolio securities to achieve its principal investment strategies.

The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those periods and that you earn a 5% return each year. The example also assumes that the fund’s operating expenses remain the same, except that it reflects the rate and duration of any fee waivers noted in the table above.

These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund’s performance.

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.</span></div><div style="margin-bottom:4pt;margin-top:2pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">The portfolio managers look for stocks of companies they believe will increase in value over time, using an investment strategy developed by the fund’s 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. </span></div><div><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:115%">Under normal market conditions, the fund’s portfolio managers seek securities of companies whose earnings, revenues or key business fundamentals are not only growing, but growing at an accelerating pace.</span></div><div style="margin-bottom:4pt;margin-top:2pt"><span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%">The fund may engage in active and frequent trading of portfolio securities to achieve its principal investment strategies.
