Example

The example below is intended to help you compare the costs of investing in the fund with the costs of investing in other mutual funds. 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 (unless otherwise indicated), that you earn a 5% return each year, and that the fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	1 year	3 years	5 years	10 years
Investor Class	$102	$323	$562	$1,246
I Class	$82	$260	$454	$1,012
Y Class	$67	$213	$372	$833
A Class	$695	$953	$1,231	$2,018
C Class	$203	$633	$1,087	$2,151
R Class	$153	$479	$828	$1,809
R5 Class	$82	$260	$454	$1,012
R6 Class	$67	$213	$372	$833

Portfolio Turnover

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. During the most recent fiscal year, the fund’s portfolio turnover rate was 42% of the average value of its portfolio.

Principal Investment Strategies

In selecting stocks for the fund, the portfolio managers look for companies of all sizes whose stock price may not reflect the company’s value. The managers attempt to purchase the stocks of these undervalued companies and hold each stock until the price has increased to, or is higher than, a level the managers believe more accurately reflects the fair value of the company. The portfolio managers use a variety of analytical research tools and techniques to help them make decisions about buying or holding securities of companies that meet their investment criteria and selling the securities of companies that do not. In addition to fundamental financial metrics, the portfolio managers may also consider environmental, social, and/or governance (ESG) data. However, the portfolio managers may not consider ESG data with respect to every investment decision and, even when such data is considered, they may conclude that other attributes of an investment outweigh ESG considerations when making decisions for the fund.

The fund may invest a portion of its assets in foreign securities when these securities meet the portfolio managers’ standards of selection.

The portfolio managers may sell stocks from the fund’s portfolio if they believe a stock no longer meets their valuation criteria, a stock’s risk parameters outweigh its return opportunity, more attractive alternatives are identified or specific events alter a stock’s prospects.

Principal Risks

•Multi-Cap InvestingRisk — The fund is a multi-capitalization fund that invests in companies of all sizes. The small and medium-sized companies in which the fund invests may be more volatile and subject to greater risk than larger companies.

•Style Risk — If the market does not consider the individual stocks purchased by the fund to be undervalued, the value of the fund’s shares may decline, even if stock prices generally are rising.

•Foreign Securities Risk — The fund may invest in foreign securities, which can be riskier than investing in U.S. securities. Securities of foreign issuers may be less liquid, more volatile and harder to value than U.S. stocks.

•Redemption Risk— The fund may need to sell securities at times it would not otherwise do so in order to meet shareholder redemption requests. Selling securities to meet such redemptions may cause the fund to experience a loss, increase the fund’s transaction costs or have tax consequences. To the extent that a large shareholder (including a fund of funds or 529 college savings plan) invests in the fund, the fund may experience relatively large redemptions as such shareholder reallocates its assets.

•Market Risk — The value of the fund’s shares will go up and down based on the performance of the companies whose securities it owns and other factors generally affecting the securities market. Market risks, including political, regulatory, economic and social developments, can affect the value of the fund’s investments. Natural disasters, public health emergencies, terrorism and other unforeseeable events may lead to increased market volatility and may have adverse long-term effects on world economies and markets generally.

•ESG Integration Risk — When the portfolio managers consider ESG data in addition to fundamental financial metrics to help them make an investment decision for the fund, the fund may perform differently than funds for which ESG data is not considered. Additionally, despite their consideration of ESG data, the portfolio managers may nonetheless invest in companies with weak, or exclude companies with strong, ESG characteristics if they conclude that other attributes of an investment outweigh ESG considerations. ESG data used by the portfolio managers often lacks standardization, consistency, and transparency, and for certain companies such data may not be available, complete, or accurate.

•Price Volatility Risk — The value of the fund’s shares may fluctuate significantly in the short term.

•Principal Loss Risk — At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund.

An investment in the fund is not a bank deposit, and it is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

1    Historical performance for the Y Class prior to its inception is based on the performance of the R6 Class shares, which have the same expenses as the Y Class shares. Since inception performance for the Y Class is based on the R6 Class inception date.

2 C Class shares automatically convert to A Class shares after approximately eight years. All returns for periods greater than eight years reflect this conversion.

3    Historical performance for the R5 Class prior to its inception is based on the performance of I Class shares, which have the same expenses as the R5 Class shares.

The after-tax returns are shown only for Investor Class shares. After-tax returns for other share classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold their fund shares through tax-deferred arrangements, such as 401(k) plans or IRAs.

Payments to Broker-Dealers and Other Financial Intermediaries

These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.
