(a)	The deferred sales charge is imposed on Class C Shares redeemed during the first year only.
(b)	The fund's investment adviser has contractually agreed to limit the fund's total operating expenses (excluding certain expenses, such as front-end or contingent deferred sales charges, taxes, leverage and borrowing expenses (such as commitment, amendment and renewal expenses on credit or redemption facilities), interest, brokerage commissions, expenses incurred in connection with any merger or reorganization, unusual or infrequently occurring expenses (such as litigation), acquired fund fees and expenses, and dividend expenses, if any) so that such expenses do not exceed 1.29% for Class A Shares, 2.04% for Class C Shares, 0.94% for Institutional Class Shares and 0.89% for Class R6 Shares through October 31, 2025. Prior to October 31, 2025, only the fund's Board may modify or terminate the expense limitation agreement. Following the contractual period, the adviser may discontinue these expense reimbursement arrangements at any time. Under certain conditions, the adviser may recapture operating expenses reimbursed and/or fees waived under these arrangements for a period of three years following the date such waiver or reimbursement occurred, provided that the recapture does not cause the fund to exceed its expense limit in effect at the time of the waiver or reimbursement, and any in effect at the time of recapture, after repayment is taken into account.

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 of your shares at the end of those periods or continued to hold them. The example also assumes that your investment has a 5% return each year, that the fund's operating expenses remain the same and that the expense reimbursement agreement remains in place for the contractual period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Class	Share Status	1 Year	3 Years	5 Years	10 Years
Class A	Sold or Held	$674		$979		$1,305		$2,225
Class C	Sold	$307		$687		$1,194		$2,587
	Held	$207		$687		$1,194		$2,587
Institutional Class	Sold or Held	$96		$360		$643		$1,453
Class R6	Sold or Held	$91		$333		$595		$1,343

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 99% of the average value of its portfolio.

Investments, Risks and Performance

Principal Investment Strategies

The fund seeks to achieve its investment objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in securities of companies that are tied economically to countries with emerging securities markets-that is, countries with securities markets that are, in the opinion of the portfolio managers, less sophisticated than more developed markets in terms of participation by investors, analyst coverage, liquidity and/or regulation. The fund will normally invest primarily in companies located in the countries represented in the fund's benchmark, the MSCI Emerging Markets Index ("Emerging Market Countries"), and have exposure to at least five Emerging Market Countries. The fund may invest a substantial portion of its assets in equity securities of companies located in China. The portfolio managers seek to invest in emerging markets equities which they believe are benefiting from change not yet fully reflected in the market. Members of the portfolio management team believe that behavioral biases of investors contribute to market inefficiencies. Their quantitative investment process begins with a proprietary investment-return forecasting model which combines behavioral factors (which seek to capitalize on human behavioral biases (i.e., systematic tendencies) from financial analysts, company management and investors), with intrinsic and valuation factors (which are expected to provide tangible measures of a company's true worth). The portfolio managers integrate this multi-factor approach with a proprietary risk model to form the basis of portfolio construction, with constraints at the individual security, country and industry levels to manage exposures relative to the benchmark. Additionally, all investment recommendations are thoroughly vetted on an individual company level to confirm the investment rationale and suitability before a purchase or sale. The fund normally invests primarily in common stocks, either directly or indirectly through depositary receipts. In addition to common stocks, equity securities in which the fund may invest include, without limitation, preferred stocks, convertible securities and warrants. The fund may invest in issuers of any size market capitalization, including smaller capitalization companies. The fund may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments. The fund may also use participatory notes ("P-Notes") or other equity-linked notes to gain exposure to issuers in certain countries. Although the fund did not invest significantly in derivative instruments as of the most recent fiscal year end, it may do so at any time.

Principal Risks

The fund may not achieve its objective(s), and it is not intended to be a complete investment program. The value of the fund's investments that supports your share value may decrease. If between the time you purchase shares and the time you sell shares the value of the fund's investments decreases, you will lose money. Investment values can decrease for a number of reasons. Conditions affecting the overall economy, specific industries or companies in which the fund invests can be worse than expected, and investments may fail to perform as the subadviser expects. As a result, the value of your shares may decrease. Purchase and redemption activities by fund shareholders may impact the management of the fund and its ability to achieve its investment objective(s). The principal risks of investing in the fund are identified below (in alphabetical order after the first eight risks).

>Market Volatility Risk: The value of the securities in the fund may go up or down in response to the prospects of individual companies and/or general economic conditions. Price changes may be short- or long-term. Local, regional or global events such as war or military conflict (e.g., Russia's invasion of Ukraine), acts of terrorism, the spread of infectious illness or other public health issue, recessions, or other events could have a significant impact on the fund and its investments, including hampering the ability of the fund's portfolio manager(s) to invest the fund's assets as intended.

>Issuer Risk: The fund will be affected by factors specific to the issuers of securities and other instruments in which the fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers.

>Equity Securities Risk:The value of the stocks held by the fund may be negatively affected by the financial market, industries in which the fund invests, or issuer-specific events. Focus on a particular style or in small or medium-sized companies may enhance that risk.

>Foreign Investing Risk: Investing in foreign securities subjects the fund to additional risks such as increased volatility; currency fluctuations; less liquidity; less publicly available information about the foreign investment; and political, regulatory, economic, and market risk.

>Emerging Market Risk: Emerging markets securities may be more volatile, or more greatly affected by negative conditions, than those of their counterparts in more established foreign markets. Such securities may also be subject to Sanctions Risk.

>Sanctions Risk: The imposition of sanctions and other similar measures could cause a decline in the value and/or liquidity of securities issued by or tied to the sanctioned country and increase market volatility and disruption in the sanctioned country and throughout the world. Sanctions and other similar measures could limit or prevent the fund from buying and selling securities (in the sanctioned country and other markets), significantly delay or prevent the settlement of transactions, and negatively impact the fund's liquidity and performance.

>Focused Investment Risk: To the extent the fund focuses its investments on a limited number of issuers, sectors, industries, geographic regions or portfolio themes, it may be subject to increased risk and volatility.

>China-Related Risk: Because the fund may invest a substantial portion of its assets in equity securities of Chinese companies, it is particularly affected by events or factors relating to China, which may increase risk and volatility.

>Small and Medium Market Capitalization Companies Risk: The fund's investments in small and medium market capitalization companies may increase the volatility and risk of loss to the fund, as compared with investments in larger, more established companies.

>Counterparty Risk: There is risk that a party upon whom the fund relies to complete a transaction will default.

>Credit Risk: If the issuer of a debt instrument fails to pay interest or principal in a timely manner, or negative perceptions exist in the market of the issuer's ability to make such payments, the price of the security may decline.

>Currency Rate Risk: Fluctuations in the exchange rates between the U.S. dollar and foreign currencies may negatively affect the value of the fund's shares.

>Depositary Receipts Risk: Investments in foreign companies through depositary receipts may expose the fund to the same risks as direct investments in securities of foreign issuers.

>Derivatives Risk: Derivatives and other similar instruments (collectively referred to in this section as "derivatives") may include, among other things, futures, options, forwards and swap agreements and may be used in order to hedge portfolio risks, create leverage or attempt to increase returns. Investments in derivatives may result in increased volatility and the fund may incur a loss greater than its principal investment.

>Leverage Risk: When the fund leverages its portfolio by borrowing or by engaging in certain types of transactions or instruments, including derivatives, the fund may be less liquid, may liquidate positions at an unfavorable time, and the volatility of the fund's value may increase.

>Liquidity Risk: Certain instruments may be difficult or impossible to sell at a time and price beneficial to the fund.

>Portfolio Turnover Risk: The fund's principal investment strategies may result in a consistently high portfolio turnover rate. See the "Portfolio Turnover" section above for more information about the impact that portfolio turnover can have on your investment.

>Preferred Stocks Risk: Preferred stocks may decline in price, fail to pay dividends when expected, or be illiquid.

>Redemption Risk: One or more large shareholders or groups of shareholders may redeem their holdings in the fund, resulting in an adverse impact on remaining shareholders in the fund by causing the fund to take actions it would not otherwise have taken.
