What is the goal of the Fund?

The Fund seeks to provide a consistently high total return from a broadly diversified portfolio of equity securities with risk characteristics similar to the Standard and Poor’s 500 Composite Stock Price Index (S&P 500 Index).

Fees and Expenses of the Fund

The following table describes the fees and expenses that you may pay if you buy and hold shares of the Fund.

ANNUAL FUND OPERATING EXPENSES (Expenses that you pay each year as a percentage of the value of your investment)
	Class R6
Management Fees	0.25%
Distribution (Rule 12b-1) Fees	NONE
Other Expenses	0.09
Dividend and Interest Expense on Short Sales	0.00
Service Fees	NONE
Remainder of Other Expenses	0.09
Acquired Fund Fees and Expenses	0.00
Total Annual Fund Operating Expenses	0.34
Fee Waivers and/or Expense Reimbursements¹	(0.09)
Total Annual Fund Operating Expenses after Fee Waivers and/or Expense Reimbursements¹	0.25

The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding acquired fund fees and expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 0.25% of the average daily net assets of the Class R6 Shares. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 10/31/20, at which time it will be determined whether such waivers will be renewed or revised. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/20 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

WHETHER OR NOT YOU SELL YOUR SHARES, YOUR COST WOULD BE:
	1 Year	3 Years	5 Years	10 Years
CLASS R6 SHARES ($)	26	100	182	422

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

What are the Fund’s main investment strategies?

Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities of U.S. companies. “Assets” means net assets plus the amount of borrowings for investment purposes. In implementing this strategy, the Fund primarily invests in the common stocks of U.S. companies in the S&P 500 Index (which includes both large cap and mid cap companies). The Fund may also invest in securities not included within the S&P 500 Index. As of September 30, 2019, the market capitalizations of the companies in the S&P 500 Index ranged from $1.7 billion to $1,061.6 billion. Sector by sector, the Fund’s weightings are similar to those of the S&P 500 Index. Within each sector, the Fund modestly overweights equity securities that it considers undervalued or fairly valued while modestly underweighting or not holding equity securities that appear overvalued. By owning a large number of equity securities within the S&P 500 Index, with an emphasis on those that appear undervalued or fairly valued, the Fund seeks returns that modestly exceed those of the S& P 500 Index over the long term with a modest level of volatility.

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions.

An issuer of a security will be deemed to be located in the United States if: (i) the principal trading market for the security is in the United States, (ii) the issuer is organized under the laws of the United States, or (iii) the issuer derives at least 50% of its revenues or profits from the United States or has at least 50% of its total assets situated in the United States.

Investment Process: In managing the Fund, the adviser employs a three-step process that combines research, valuation and stock selection. The adviser takes an in-depth look at company prospects over a period as long as five years, which is designed to provide insight into a company’s real growth potential. The research findings allow the adviser to rank the companies in each sector group according to their relative value. As a part of its investment process, the adviser seeks to assess the impact of environmental, social and governance factors (including accounting and tax policies, disclosure and investor communication, shareholder rights and remuneration policies) on the cash

flows of many companies in which it may invest to identify issuers that the adviser believes will be negatively impacted by such factors relative to other issuers. These determinations may not be conclusive and securities of such issuers may be purchased and retained by the Fund.

On behalf of the Fund, the adviser then buys and sells equity securities, using the research and valuation rankings as a basis.

Along with attractive valuation, the adviser often considers a number of other criteria:

•	catalysts that could trigger a rise in a stock’s price
•	impact on the overall risk of the portfolio relative to the S&P 500 Index
•	high perceived potential reward compared to perceived potential risk
•	possible temporary mispricings caused by apparent market overreactions

The adviser may sell a security as its valuations or rankings change or if more attractive investments become available.

The Fund’s Main Investment Risks

The Fund is subject to management risk, and may not achieve its objective if the adviser’s expectations regarding particular instruments or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund’s performance and ability to meet its investment objective.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, terrorism, regulatory events and government controls.

Large Cap Company Risk. Because the Fund invests principally in large cap company securities, it may underperform other funds during periods when the Fund’s securities are out of favor.

Mid Cap Company Risk. Investments in mid cap companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investments in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Derivatives Risk. Derivatives, including futures, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund’s original investment. Certain derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation.

Industry and Sector Focus Risk. At times the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, its shares’ values may fluctuate in response to events affecting that industry or sector.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.
