Example. The example below 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, except as shown below, redeem all of your shares at the end of those periods. The example also assumes that:

•

Your investment has a 5% return each year

•

The Fund’s operating expenses remain the same

•

You reinvest all dividends and distributions.

Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Share Classes	Year 1	Year 3	Year 5	Year 10
A	$656	$880	$1,123	$1,816
C	$290	$588	$1,011	$2,190
I	$82	$255	$444	$990
R3	$145	$449	$776	$1,702
R4	$113	$353	$612	$1,352
R5	$82	$255	$444	$990
R6	$72	$224	$390	$871
Y	$82	$255	$444	$990
F	$72	$224	$390	$871

If you did not redeem your shares:

$190

$588

$1,011

$2,190

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 fiscal year ended October 31, 2023, the Fund’s portfolio turnover rate was 68% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGY. The Fund normally invests at least 65% of its net assets in equity securities, including non-dollar securities, of foreign issuers. The Fund diversifies its investments among a number of different countries throughout the world, with no limit on the amount of assets that may be invested in each country. The securities in which the Fund invests are denominated in both U.S. dollars and foreign currencies and generally are traded in foreign markets. The Fund may invest in companies domiciled in emerging markets as a percentage of its net assets up to the greater of: (a) 25% or (b) the weight of emerging markets in the MSCI ACWI ex USA Index plus 10%. The Fund may invest in opportunities across the market capitalization spectrum, but under normal circumstances invests primarily in mid and large capitalization companies.

The sub-adviser, Wellington Management Company LLP (“Wellington Management”), seeks to invest in companies with underappreciated assets, improving return on capital and/or stocks that it believes are mispriced by the market due to short-term issues. Wellington Management conducts fundamental research on individual companies to identify securities for purchase or sale. As part of its fundamental analysis, Wellington Management may evaluate, for example, a company’s business environment, management quality, balance sheet, income statement, anticipated earnings, revenues and dividends, and other related measures or indicators of value. Wellington Management also may consider financially material environmental, social, and/or governance (“ESG”) characteristics (where available for a company) to assess the risk and return potential of a company. Portfolio construction is driven primarily by bottom-up stock selection, with region, country and sector weightings being secondary factors. Based on market or economic conditions, the Fund may, through its normal bottom-up stock selection process, focus in one or more sectors of the market.

PRINCIPAL RISKS. The principal risks of investing in the Fund are described below. When you sell your shares they may be worth more or less than what you paid for them, which means that you could lose money as a result of your investment. 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. As with any fund, there is no guarantee that the Fund will achieve its investment objective.

Market Risk – Market risk is the risk that one or more markets in which the Fund invests will go down in value, including the possibility that the markets will go down sharply and unpredictably. Securities of a company may decline in value due to its financial prospects and activities, including certain operational impacts, such as data breaches and cybersecurity attacks. Securities may also decline in value due to general market and economic movements and trends, including adverse changes to credit markets, or as a result of other events such as geopolitical events, natural disasters, or widespread pandemics (such as COVID-19) or other adverse public health developments.

Foreign Investments Risk – Investments in foreign securities may be riskier, more volatile, and less liquid than investments in U.S. securities. Differences between the U.S. and foreign regulatory regimes and securities markets, including the less stringent investor protection, less stringent accounting, corporate governance, financial reporting and disclosure standards of some foreign markets, as well as political and economic developments in foreign countries

and regions and the U.S. (including the imposition of sanctions, tariffs, or other governmental restrictions), may affect the value of the Fund’s investments in foreign securities. Changes in currency exchange rates may also adversely affect the Fund’s foreign investments.

Emerging Markets Risk – The risks related to investing in foreign securities are generally greater with respect to investments in companies that conduct their principal business activities in emerging markets or whose securities are traded principally on exchanges in emerging markets. The risks of investing in emerging markets include risks of illiquidity, increased price volatility, smaller market capitalizations, less government regulation and oversight, less extensive and less frequent accounting, financial, auditing and other reporting requirements, significant delays in settlement of trades, risk of loss resulting from problems in share registration and custody and substantial economic and political disruptions. In addition, the imposition of exchange controls (including repatriation restrictions), sanctions, confiscations, trade restrictions (including tariffs) and other government restrictions by the United States and other governments may also result in losses. Frontier markets are those emerging markets that are considered to be among the smallest, least mature and least liquid, and as a result, the risks of investing in emerging markets are magnified in frontier markets.

Currency Risk – The risk that the value of the Fund’s investments in foreign securities or currencies will be affected by the value of the applicable currency relative to the U.S. dollar. When the Fund sells a foreign currency or foreign currency denominated security, its value may be worth less in U.S. dollars even if the investment increases in value in its local market. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk, as the revenue earned by issuers of these securities may also be affected by changes in the issuer’s local currency.

Equity Risk – The risk that the price of equity or equity related securities may decline due to changes in a company’s financial condition and overall market and economic conditions.

Mid-Cap Securities Risk – The securities of mid-capitalization companies generally trade in lower volumes and are generally subject to greater and less predictable price changes than the securities of larger capitalization companies.

Large Cap Securities Risk – The securities of large market capitalization companies may underperform other segments of the market because such companies may be less responsive to competitive challenges and opportunities and may be unable to attain high growth rates during periods of economic expansion.

Active Investment Management Risk – The risk that, if the sub-adviser’s investment strategy does not perform as expected, the Fund could underperform its peers or lose money. Although the sub-adviser considers several factors when making investment decisions, the sub-adviser may not evaluate every factor prior to investing in a company or issuer, and the sub-adviser may determine that certain factors are more significant than others.

Sector Risk – To the extent the Fund invests more heavily in a particular sector or sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, from the broader market.

Regional/Country Focus Risk – To the extent that the Fund focuses its investments in a particular geographic region or country, the Fund may be subject to increased currency, political, regulatory, economic and other risks associated with that region or country. A natural or other disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in the specific geographic region. As a result, the Fund may be subject to greater price volatility and risk of loss than a fund holding more geographically diverse investments.

ESG Integration Risk – Integrating financially material ESG analysis into the investment process carries the risk that the Fund may perform differently from funds that do not integrate ESG into their analysis, or funds that evaluate different ESG characteristics. ESG characteristics are one of several factors that may be considered and as a result, the Fund’s investments may not have favorable ESG characteristics or high ESG ratings.

Large Shareholder Transaction Risk – The Fund may experience adverse effects when certain large shareholders redeem or purchase large amounts of shares of the Fund. Such redemptions may cause the Fund to sell securities at times when it would not otherwise do so or borrow money (at a cost to the Fund), which may negatively impact the Fund’s performance and liquidity. Similarly, large purchases 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. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs.

The Fund is subject to certain other risks. For more information regarding risks and investments, please see “Additional Information Regarding Investment Strategies and Risks” and “More Information About Risks” in the Fund’s statutory prospectus.
