Investment Objective:Seeks maximum long-term total return.

Fees and Expenses:This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below.

Shareholder Fees (fees paid directly from your investment)

Class	I
Maximum sales charge (load) imposed on purchases (as a percentage of offering price)	None
Maximum deferred sales charge (load) (as a percentage of purchase price or redemption proceeds, whichever is lower)	None

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Management fees1	0.88%
Distribution and service (12b-1) fees	None
Other expenses	0.17%
Total annual fund operating expenses	1.05%

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 and then redeem all shares at the end of those periods. The Example also assumes that your investment has 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
Class I	$107	$334	$579	$1,283

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 portfolio turnover rate for the fund was 18% of the average value of its portfolio.

Principal Investment Strategies:The fund's sub-adviser, Thompson, Siegel & Walmsley LLC (the "sub-adviser"), invests under normal circumstances, at least 80% of the fund's net assets (plus the amount of borrowings, if any, for investment purposes) in small-capitalization companies ("small-cap companies"). The sub-adviser considers small-cap companies to be those with market capitalizations within the range of the MSCI EAFE Small Cap Index, a benchmark of the fund, at the time of investment. As of December 31, 2023, the market capitalization range of the MSCI EAFE Small Cap Index was between $153.4 million and $21.2 billion. The fund primarily invests in equity securities of small-cap companies located outside the United States. The sub-adviser seeks stocks that it believes are undervalued. The sub-adviser expects capital growth to be the predominant component of the fund's total return.

Generally, the fund will invest primarily in common stocks of companies listed on foreign securities exchanges, but it may also invest in depositary receipts including American Depositary Receipts ("ADRs"), Global Depositary Receipts ("GDRs") and European Depositary Receipts ("EDRs"). Although the fund will emphasize small-cap companies, it may invest in companies of varying sizes as measured by assets, sales or market capitalization. The fund will invest primarily in securities of companies domiciled in developed markets, but may invest up to 25% of its net assets in securities of companies in emerging markets. The sub-adviser defines emerging markets countries as those countries included in the MSCI Emerging Markets Index and other countries with similar emerging market characteristics as determined by the sub-adviser. The sub-adviser seeks to diversify the fund's investments around the world and within markets in an effort to moderate specific country and currency risks.

The sub-adviser employs a relative value process utilizing a combination of quantitative and qualitative methods based on a four-factor valuation screen designed to outperform the MSCI Europe, Australasia and Far East ("EAFE") Small Cap Index. The sub-adviser also performs rigorous fundamental analysis. The fund's portfolio is typically composed of approximately 80-140 securities

as a result of this process. Value stocks as a group may be out of favor and underperform the overall equity market for a long period of time, for example, while the market favors "growth" stocks.

The sub-adviser employs a consistent sell discipline, regularly reviewing the investment thesis and valuation for each stock and selling those where the catalyst is no longer valid or where another stock presents a significantly better combination of risk and expected reward. The sub-adviser trims and reviews for elimination any stock that suffers a significant negative earnings revision and eliminates any stock whose market capitalization reaches twice the maximum market cap of the MSCI EAFE Small Cap Index, a benchmark of the fund.

Principal Risks:Risk is inherent in all investing. Many factors and risks affect the fund's performance, including those described below. The value of your investment in the fund, as well as the amount of return you receive on your investment, may fluctuate significantly day to day and over time. You may lose part or all of your investment in the fund or your investment may not perform as well as other similar investments. The following is a summary description of principal risks (in alphabetical order after certain key risks) of investing in the fund. An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.You may lose money if you invest in this fund.

Market - The market prices of the fund's securities or other assets may go up or down, sometimes rapidly or unpredictably, due to factors such as economic events, inflation, changes in interest rates, governmental actions or interventions, actions taken by the U.S. Federal Reserve or foreign central banks, market disruptions caused by tariffs, trade disputes or other factors, political developments, armed conflicts, economic sanctions, cybersecurity events, investor sentiment, the global and domestic effects of widespread or local health, weather or climate events, and other factors that may or may not be related to the issuer of the security or other asset. If the market prices of the fund's securities and assets fall, the value of your investment in the fund could go down.

Economies and financial markets throughout the world are increasingly interconnected. Events or circumstances in one or more countries or regions could be highly disruptive to, and have profound impacts on, global economies or markets. As a result, whether or not the fund invests in securities of issuers located in or with significant exposure to the countries directly affected, the value and liquidity of the fund's investments may go down.

Value Investing - The prices of securities the sub-adviser believes are undervalued may not appreciate as anticipated or may go down. The value approach to investing involves the risk that stocks may remain undervalued, undervaluation may become more severe, or perceived undervaluation may actually represent intrinsic value. Value stocks as a group may be out of favor and underperform the overall equity market for a long period of time, for example, while the market favors "growth" stocks.

Small Capitalization Companies - The fund will be exposed to additional risks as a result of its investments in the securities of small capitalization companies. Small capitalization companies may be more at risk than larger capitalization companies because, among other things, they may have limited product lines, operating

history, market or financial resources, or because they may depend on limited management groups. Securities of small capitalization companies are generally more volatile than and may underperform larger capitalization companies, may be harder to sell at times and at prices the portfolio managers believe appropriate and may offer greater potential for losses.

Foreign Investments - Investing in securities of foreign issuers or issuers with significant exposure to foreign markets involves additional risks. Foreign markets can be less liquid, less regulated, less transparent and more volatile than U.S. markets. The value of the fund's foreign investments may decline, sometimes rapidly or unpredictably, because of factors affecting the particular issuer as well as foreign markets and issuers generally, such as unfavorable government actions, including nationalization, expropriation or confiscatory taxation, reduction of government or central bank support, tariffs and trade disruptions, sanctions, political or financial instability, social unrest or other adverse economic or political developments. Foreign investments may also be subject to different accounting practices and different regulatory, legal, auditing, financial reporting and recordkeeping standards and practices, and may be more difficult to value than investments in U.S. issuers. Certain foreign clearance and settlement procedures may result in an inability to execute transactions or delays in settlement.

Currency - The value of a fund's investments in securities denominated in foreign currencies increases or decreases as the rates of exchange between those currencies and the U.S. dollar change. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk. Currency exchange rates can be volatile and may fluctuate significantly over short periods of time. Currency conversion costs and currency fluctuations could reduce or eliminate investment gains or add to investment losses. A fund may be unable or may choose not to hedge its foreign currency exposure or any hedge may not be effective.

Equity Securities - Equity securities generally have greater risk of loss than debt securities. Stock markets are volatile and the value of equity securities may go up or down, sometimes rapidly and unpredictably. The market price of an equity security may fluctuate based on overall market conditions, such as real or perceived adverse economic or political conditions or trends, tariffs and trade disruptions, inflation, substantial economic downturn or recession, changes in interest rates, or adverse investor sentiment. The market price of an equity security also may fluctuate based on real or perceived factors affecting a particular industry or industries or the company itself. If the market prices of the equity securities owned by the fund fall, the value of your investment in the fund will decline. The fund may lose its entire investment in the equity securities of an issuer. A change in financial condition or other event affecting a single issuer may adversely impact securities markets as a whole.

Liquidity - The fund may make investments that are illiquid or that become illiquid after purchase. Illiquid investments can be difficult to value, may trade at a discount from comparable, more liquid investments, and may be subject to wide fluctuations in value. Liquidity risk may be magnified in rising interest rate or volatile environments. If the fund is forced to sell an illiquid investment to meet redemption requests or other cash needs, the fund may be forced to sell at a substantial loss or may not be able to sell at all. Liquidity of particular investments, or even entire asset

classes, including U.S. Treasury securities, can deteriorate rapidly, particularly during times of market turmoil, and those investments may be difficult or impossible for the fund to sell. This may prevent the fund from limiting losses.

Valuation - Certain investments may be more difficult to value than other types of investments. The sales price the fund could receive for any particular portfolio investment may differ from the fund's valuation of the investment, particularly for securities that trade in thin or volatile markets, that are priced based upon valuations provided by third party pricing services, or that are valued using a fair value methodology. These differences may increase significantly and affect fund investments more broadly during periods of market volatility. Investors who purchase or redeem fund shares on days when the fund is holding fair-valued securities may receive fewer or more shares or lower or higher redemption proceeds than they would have received if the fund had not fair-valued securities or had used a different valuation methodology. The fund's ability to value its investments may also be impacted by technological issues and/or errors by pricing services or other third party service providers. Fair value pricing involves subjective judgment, which may prove to be incorrect.

Focused Investing - To the extent the fund invests in a limited number of countries, regions, sectors, industries or market segments, in a limited number of issuers, or in issuers in related businesses or that are subject to related operating risks, the fund will be more susceptible to negative events affecting those countries, regions, sectors, industries, segments or issuers, and the value of its shares may be more volatile than if it invested more widely.

Management - The value of your investment may go down if the investment manager's or sub-adviser's judgments and decisions are incorrect or otherwise do not produce the desired results, or if the investment strategy does not work as intended. You may also suffer losses if there are imperfections, errors or limitations in the quantitative, analytic or other tools, resources, information and data used, investment techniques applied, or the analyses employed or relied on, by the investment manageror sub-adviser, if such tools, resources, information or data are used incorrectly or otherwise do not work as intended, or if the investment manager's or sub-adviser's investment style is out of favor or otherwise fails to produce the desired results. Any of these things could cause the fund to lose value or its results to lag relevant benchmarks or other funds with similar objectives.

Active Trading - The fund may engage in active trading of its portfolio. Active trading will increase transaction costs and could detract from performance. Active trading may be more pronounced during periods of market volatility and may generate greater amounts of short-term capital gains.

Cybersecurity - Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain access to fund assets, fund or shareholder data (including private shareholder information), or proprietary information, cause the fund or its service providers (including, but not limited to, the fund's investment manager, any sub-adviser(s), transfer agent, distributor, custodian, fund accounting agent and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality, or prevent fund investors from purchasing, redeeming or exchanging shares, receiving distributions or receiving timely information regarding the fund or their investment in the fund.

Cybersecurity incidents may result in financial losses to the fund and its shareholders, and substantial costs may be incurred in order to prevent or mitigate any future cybersecurity incidents.

Depositary Receipts - Depositary receipts are generally subject to the same risks as are the foreign securities that they evidence or into which they may be converted, and they may be less liquid than the underlying shares in their primary trading market. In addition, depositary receipts expose the fund to risk associated with the non-uniform terms that apply to depositary receipt programs, credit exposure to the depositary bank and to the sponsors and other parties with whom the depositary bank establishes the programs. Holders of depositary receipts may have limited voting rights, and investment restrictions in certain countries may adversely impact the value of depositary receipts because such restrictions may limit the ability to convert equity shares into depositary receipts and vice versa.

Emerging Markets - Investments in securities of issuers located or doing business in emerging markets are subject to heightened foreign investments risks and may experience rapid and extreme changes in value. Emerging market countries tend to have less developed and less stable economic, political and legal systems and regulatory and accounting standards, may have policies that restrict investment by foreigners or that prevent foreign investors such as the fund from withdrawing their money at will, and are more likely to experience nationalization, expropriation and confiscatory taxation. Emerging market securities may have low trading volumes and may be or become illiquid. In addition, there may be significant obstacles to obtaining information necessary for investigations into or litigation against issuers located in or operating in emerging market countries, and shareholders may have limited legal remedies.

Large Shareholder - A significant portion of the fund's shares may be owned by one or more investment vehicles or institutional investors. Transactions by these large shareholders may be disruptive to the management of the fund. For example, the fund may experience large redemptions and could be required to sell securities at a time when it may not otherwise desire to do so. Such transactions may increase the fund's brokerage and/or other transaction costs. These transactions may also accelerate the realization of taxable capital gains to shareholders if such sales of investments result in capital gains. In addition, sizeable redemptions could cause the fund's total expenses to increase.
