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:

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, 2025, the Fund's portfolio turnover rate was 36% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGY. The Fund seeks to achieve its investment objective by investing in companies that Wellington Management Company LLP ("Wellington Management") believes are globally competitive and exhibit the potential for growth. As part of this analysis, Wellington Management seeks to identify companies that it believes exhibit visible and imminent inflection points that can result in earnings growth and margin expansion.

Under normal circumstances, the Fund 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 sectors and countries throughout the world, with no limit on the amount of assets that may be invested in each sector or country. Although some consideration is given to ensuring sector and country diversification, allocation of investments among sectors and countries is primarily the result of security selection. The Fund may invest in securities of companies that conduct their principal business activities in emerging markets or whose securities are traded principally on exchanges in emerging markets as a percentage of its net assets up to the greater of: (a) 30% or (b) the weight of emerging markets in the MSCI ACWI ex USA Growth Index plus 15%. The Fund may invest in securities of any market capitalization, but tends to focus on companies with market capitalizations greater than $3 billion. 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. The Fund typically employs a focused portfolio investing style (i.e., a portfolio consisting of a relatively small number of holdings).

An issuer is deemed to be a "foreign issuer" if one or more of the following criteria is met: (a) an issuer's domicile or location of headquarters is in a foreign country; (b) an issuer is doing a substantial amount of business outside the United States, which the Fund considers to be an issuer that derives at least 50% of its revenues or profits outside the United States or has at least 50% of its sales or assets outside the United States; or (c) the principal trading market for a security of an issuer is located in a foreign country.

Effective upon the compliance date of amendments to Rule 35d-1 (currently, March 1, 2027), under normal circumstances, the Fund will invest at least 80% of its assets in securities of growth companies. Wellington Management will determine whether a company is a growth company based on traditional and other measures of growth, such as whether the company is included within a third-party growth index (e.g. MSCI ACWI ex USA Growth Index) and/or whether the company exhibits growth characteristics based on certain metrics, such as earnings per share (EPS) growth and/or revenue growth. A company may be determined to be a growth company under any of these factors.

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 (or threat thereof), 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 foreign investments. 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 could cause losses to the Fund and/or negatively affect liquidity. 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.

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.

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.

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.

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.

Growth Investing Style Risk -  If the sub-adviser incorrectly assesses a company's prospects for growth or how other investors will value the company's growth, then the price of the company's stock may decrease, or may not increase to the level anticipated by the sub-adviser. In addition, growth stocks may be more volatile than other stocks because they are more sensitive to investors' perceptions of the issuing company's growth potential. Also, the growth investing style may over time go in and out of favor. At times when the investing style used by the Fund is out of favor, the Fund may underperform other equity funds that use different investing styles.

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.

Focused Portfolio Risk -  Because the Fund may invest in a limited number of companies, the Fund is subject to greater risk of loss if any of those securities decline in price.

Volatility Risk -  The Fund's investments may fluctuate in value over a short period of time. This may cause the Fund's net asset value per share to experience significant changes in value over short periods of time.

Liquidity Risk -  The risk that the market for a particular investment or type of investment is or becomes relatively illiquid, making it difficult for the Fund to sell that investment at an advantageous time or price. Illiquidity may be due to events relating to the issuer of the securities, market events, rising interest rates, economic conditions or investor perceptions. Illiquid securities may be difficult to value and their value may be lower than the market price of comparable liquid securities, which would negatively affect the Fund's performance.

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.

Average Annual Total Returns. The table below shows returns for the Fund over time compared to those of two indices. The MSCI ACWI ex USA Growth Index (Net) serves as the Fund's performance index because the Fund's investment manager believes it is more representative of the Fund's investment strategy.
