In connection with this change, effective April 5, 2023, the third and fourth paragraphs under “Principal Investment Strategies” on page 2 will be replaced with the following:

The fund’s integrated approach to investing combines fundamental analysis and quantitative models to identify stocks that could be included in the portfolio. Stocks are selected based on a variety of metrics such as a company’s valuation, profitability, stability, earnings quality, management capital allocation actions, and indicators of near-term appreciation potential.

As part of the stock selection process, the adviser focuses primarily on companies that, in the adviser’s opinion, are capable of achieving and sustaining above-average, long-term earnings growth.

At times, the fund may have a significant portion of its assets invested in the same economic sector.

In addition, effective April 5, 2023, the third and fourth paragraphs under “Principal Investment Strategies” on page 10 of the prospectus will be replaced with the following:

The fund’s integrated approach to investing combines fundamental analysis and quantitative models to identify stocks that could be included in the portfolio. The fund draws on the adviser’s experience in small-cap investing and takes into account both its quantitative and fundamental research capabilities. The portfolio is typically constructed in a “bottom up” manner, an approach that focuses more on evaluations of individual stocks than on analyses of overall economic trends and market cycles. Stocks are selected based on a variety of metrics such as a company’s valuation, profitability, stability, earnings quality, management capital allocation actions, and indicators of near-term appreciation potential.

As part of the stock selection process, the adviser focuses primarily on companies that, in the adviser’s opinion, are capable of achieving and sustaining above-average, long-term earnings growth. The adviser employs various growth metrics, such as a company’s historical and forecasted sales and earnings growth rates.

At times, the fund may have a significant portion of its assets invested in the same economic sector.
