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 (except that the example reflects the fee waiver and/or expense reimbursement arrangement reflected in the table above for only the first year)

•

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	$665	$917	$1,189	$1,963
C	$297	$624	$1,076	$2,332
I	$90	$281	$488	$1,084
R3	$144	$461	$801	$1,762
R4	$113	$368	$642	$1,426
R5	$83	$274	$481	$1,078
R6	$70	$238	$420	$947
Y	$81	$270	$474	$1,065
F	$70	$238	$420	$947

If you did not redeem your shares:

$197

$624

$1,076

$2,332

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 34% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGY. The Fund seeks to achieve its objective by investing in equity securities of issuers located throughout the world, including non-dollar securities and securities of emerging market issuers. The Fund will normally invest at least 80% of its assets in securities of issuers that Wellington Management Company LLP (“Wellington Management”), the Fund’s sub-adviser, determines meet its impact investing criteria.

For purposes of determining which companies meet its impact investing criteria, Wellington Management uses its proprietary research to identify companies that focus their core goods and services in areas that it believes are likely to address major social and environmental challenges. Wellington Management focuses on three broad impact areas: life essentials; human empowerment; and the environment. Wellington Management then targets specific themes that fit within this impact investing criteria. The impact themes align with many of the UN’s Sustainable Development Goals. As of March 1, 2024, these impact themes include sustainable agriculture and nutrition, health, clean water and sanitation, affordable housing, education and job training, financial inclusion, narrowing the digital divide, safety and security, alternative energy, resource stewardship, and resource efficiency. These areas are subject to change without notice to shareholders. Within this universe of companies, Wellington Management conducts fundamental analysis to identify what it believes to be attractive investments across economic sectors within both developed and emerging countries. As part of its fundamental analysis, Wellington Management may evaluate, for example, a company’s industry structure, asset quality, business environment, management quality, balance sheet, income statement, anticipated earnings, growth prospects, revenues and dividends, and other related measures or indicators of value. In addition to its focus on impact investing, Wellington Management also may consider environmental, social, and/or governance (“ESG”) characteristics (where available for a company) to assess the risk and return potential of a company.

The Fund may invest in companies of any market capitalization, including small and mid capitalization securities, located anywhere in the world, including the United States. Although the Fund has no limit on the amount it may invest in any single sector, it generally can be expected to emphasize investments in the industrials, health care, and information technology sectors, as these sectors tend to include companies that address major social and/or environmental challenges. The Fund may also invest in depositary receipts or other securities that are convertible into securities of foreign issuers and could, at times hold a portion of its assets in cash. Under normal circumstances, the Fund will invest at least 40% of its net assets in foreign securities or derivative instruments or other investments with exposure to foreign securities of at least three different countries outside the United States. During periods of unfavorable market conditions, the Fund may reduce its exposure to foreign securities, but typically will continue to invest at least 30% of its net assets in foreign securities as described above. Investments are deemed to be “foreign”

if: (a) an issuer’s domicile or location of headquarters is in a foreign country; (b) an issuer derives a significant proportion (at least 50%) of its revenues or profits from goods produced or sold, investments made, or services performed in a foreign country or has at least 50% of its assets situated in a foreign country; (c) the principal trading market for a security is located in a foreign country; or (d) it is a foreign currency.

In addition to identifying investment opportunities through bottom-up fundamental research, Wellington Management generally excludes companies from the Fund’s investment universe that it determines to be primarily engaged in the following businesses: tobacco, firearms, defense, nuclear, coal, petroleum, alcohol, adult entertainment and gambling. Wellington Management believes that investment in such companies does not align with its impact investing criteria. These exclusions may be updated periodically by Wellington Management to, among other things, add or remove exclusion categories.

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.

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 and Small Cap Securities Risk – Investments in mid- and small-capitalization companies involve greater risks than investments in larger, more established companies. Many of these companies are young and have limited operating or business history. These securities may be subject to more abrupt or erratic price movements and may lack sufficient market liquidity, and these issuers often face greater business risks, including the risk of bankruptcy.

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.

Impact Investing Risk – The Fund’s impact investing focus may affect the Fund’s exposure to certain companies or industries and the Fund may forego certain investment opportunities. The Fund’s relative investment performance may also be impacted depending on whether such investments are in or out of favor with the market. The Fund may underperform other funds that do not seek to invest in companies based on impact investing criteria. Certain

companies focused on sustainable energy and climate change solutions may be dependent on, and significantly affected by, developing technologies, short product life cycles, competition from new market entrants, fluctuations in energy prices and supply and demand of alternative energy sources. These companies also may be dependent on the government policies of U.S. and foreign governments, including tax incentives and subsidies, as well as on political support for certain environmental initiatives. The sub-adviser’s analysis of determining which companies meet its impact investing criteria is a subjective determination. As a result, the Fund may invest in companies that do not reflect the beliefs and values of any particular investor. Further, the regulatory landscape with respect to impact investing in the United States is still developing and future rules and regulations may require the Fund to modify or alter its investment process with respect to impact investing.

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 – The Fund’s investments may be focused in securities of companies in certain sectors of the securities markets, which may cause the Fund’s performance to be sensitive to developments affecting those sectors generally or companies in those sectors.

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.
