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 examples, affect the Fund’s performance. During the fiscal year ended October 31, 2019, the Fund's portfolio turnover rate was [ ]% of the average value of its portfolio.

Principal Investment Strategy. The Fund seeks to achieve its objective by investing in securities of U.S. and foreign issuers, including non-dollar securities and securities of emerging market issuers. The Fund may invest in common and preferred stocks, convertible securities and warrants of companies of any market capitalization. The Fund focuses its investments on equity securities and equity related investments. Under normal market conditions, the Fund invests at least 80% of its assets in securities of issuers that seek opportunities to address or benefit from climate change, which include but are not limited to companies classified as promoting clean and/or efficient energy, sustainable transportation, water and/or resource management, companies exhibiting low-carbon leadership and businesses that service such companies. The Fund employs a “multi-manager” approach whereby portions of the Fund’s assets are allocated among sub-advisers. Hartford Funds Management Company, LLC (the "Investment Manager") is responsible for the management of the Fund and supervision of the Fund’s sub-advisers: Wellington Management Company LLP (“Wellington Management”), and Schroders, comprised of Schroder Investment Management North America Inc. (“SIMNA”) and Schroder Investment Management North America Limited (“SIMNA Ltd.,” together with SIMNA, “Schroders”). Each sub-adviser manages its segment of the Fund’s assets to correspond with its distinct investment style and strategy, as described below, in a manner consistent with the Fund’s investment objective, strategies, and restrictions. The Investment Manager may allocate assets from or towards each sub-adviser from time to time and may reallocate assets between the sub-advisers. Wellington Management and Schroders act independently of each other and each uses its own methodology for selecting investments.

Wellington Management: For its portion of the Fund, Wellington Management uses fundamental research, bottom-up approach and analysis to identify companies it believes represent attractive investments and also address environmental challenges and/or seek to improve the efficiency of resource consumption. In doing so, Wellington Management invests the Fund's assets in companies engaged in low carbon electricity, energy efficiency, low carbon transportation, water and resource management, and/or climate resilient infrastructure, or otherwise involved in seeking to address environmental challenges and/or improve the efficiency of resource consumption. Although Wellington Management may invest the Fund's assets across different sectors and countries, including emerging

4

market issuers, and has no limit on the amount it may invest in any single sector or country, it generally can be expected to emphasize investments in the utilities and industrial sectors, as these sectors tend to include companies that address environmental challenges and/or seek to improve the efficiency of resource consumption. Wellington Management generally expects to exclude companies that have significant exposure to fossil fuels. The Fund may invest in securities of issuers of any market capitalization, including mid-capitalization and small-capitalization securities. Wellington Management’s segment of the Fund is not explicitly screened for socially responsible issuers, but Wellington Management considers environmental, social, and governance (ESG) factors as part of its investment process, and the approach excludes major fossil fuel companies.

Schroders: For its portion of the Fund, Schroders seeks to exploit opportunities in the securities of companies that it believes have already recognized threats posed by climate change and are embracing these challenges ahead of their peers, companies that form part of the solution to problems arising from climate change or companies that seek to benefit from efforts to accommodate or limit the impact of global climate change. These companies can typically be classified belonging to one or more themes related to climate change, including clean energy, energy efficiency, environmental resources, sustainable transportation, and low carbon leaders. Schroders relies on a fundamental, research-driven, bottom-up approach to identify issuers it believes will benefit from efforts to accommodate or limit the impact of global climate change and have the potential for capital growth. Schroders considers factors such as a company’s potential for above average earnings growth, a security’s attractive relative valuation, whether a company has proprietary advantages, and certain ESG criteria. Schroders excludes major fossil fuel companies from its investment universe. Although Schroders may invest the Fund's assets across different sectors and countries, including emerging market issuers, and has no limit on the amount it may invest in any single sector or country, it generally can be expected to emphasize investments in the industrial sectors, as this sector tends to include companies that are beneficiaries of efforts to mitigate or adapt to the impact of climate change.

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.

Multi-Manager Risk −The Fund’s performance depends on the ability of the Investment Manager in selecting, overseeing, and allocating Fund assets to the sub-advisers. The sub-advisers’ investment styles may not be complementary. Wellington Management and Schroders make investment decisions independently of one another, and may make decisions that conflict with each other. For example, it is possible that one sub-adviser may purchase an investment for the Fund at the same time that the other sub-adviser sells the same investment, resulting in higher expenses without accomplishing any net investment result; or that the sub-advisers purchase the same investment at the same time, without aggregating their transactions, resulting in higher expenses. Moreover, the Fund’s multi-manager approach may result in the Fund investing a significant percentage of its assets in certain types of investments, which could be beneficial or detrimental to the Fund’s performance depending on the performance of those investments and the overall market environment.

Active Investment Management Risk −The risk that, if the sub-advisers’ investment strategies do not perform as expected, the Fund could underperform its peers or lose money.

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 small capitalization and mid 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.

5​

Foreign Investments Risk −Investments in foreign securities may be riskier than investments in U.S. securities. Differences between the U.S. and foreign regulatory regimes and securities markets, including the less stringent investor protection 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. Certain European countries in which the Fund may invest have recently experienced significant volatility in financial markets and may continue to do so in the future. The impact of the United Kingdom’s intended departure from the European Union, commonly known as “Brexit,” and the potential departure of one or more other countries from the European Union may have significant political and financial consequences for global markets. This may adversely impact Fund performance.

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, less extensive and less frequent accounting, financial 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. 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.

Climate Change Investment Focus Risk −The Fund’s focus on securities of issuers that seek opportunities to address or benefit from climate change may affect the Fund’s exposure to certain sectors or types of investments. The Fund's relative investment performance may also be impacted depending on whether such sectors or investments are in or out of favor with the market. Certain investments may be dependent on U.S. and foreign government policies, including tax incentives and subsidies, as well as on political support for certain environmental initiatives and developments affecting companies focused on sustainable energy and climate change solutions generally. In addition, under certain market conditions, the Fund may underperform funds that invest in a broader array of investments. The Fund’s exclusion of investments in companies with significant fossil fuel exposure, in particular, may adversely affect the Fund’s relative performance at times when such investments are performing well.

Sector Risk −The Fund’s investments may be focused in securities of companies in the utilities and industrials 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.

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.

Securities Lending Risk −The Fund may engage in securities lending. The Fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

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.

​

Your actual costs may be higher or lower. Based on these assumptions, you would pay the following expenses if you sell all of your shares at the end of each time period indicated:

You would pay the following expenses if you did not redeem your shares:

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 examples, affect the Fund’s performance. During the fiscal year ended October 31, 2019, the Fund’s portfolio turnover rate was [ ]% of the average value of its portfolio.

Principal Investment Strategy. Under normal circumstances, the Fund invests at least 80% of its assets in equity securities of companies in emerging markets. The sub-adviser, Wellington Management Company LLP (“Wellington Management”), uses a quantitative multifactor approach to bottom-up stock selection, using a broad set of individual fundamental stock characteristics to model each stock’s relative attractiveness, with a focus on those factors that have been demonstrated historically to drive market returns. The Fund will typically seek to be broadly diversified across countries, sectors and industries represented in the MSCI Emerging Markets Index, although the extent of that representation may vary. The Fund has no limit on the amount of assets that may be invested in each country. Securities in which the Fund invests are denominated in both U.S. dollars and foreign currencies and may trade in both U.S. and foreign markets. The Fund will 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. Emerging markets are those markets (1) included in emerging market or equivalent classifications by the United Nations (and its agencies); (2) having per capita income in the low to middle ranges, as determined by the World Bank; or (3) the Fund’s benchmark index provider designates as emerging. The Fund may invest in securities of foreign issuers in the form of depositary receipts or other securities that are convertible into securities of foreign issuers. The Fund may invest in opportunities across the market capitalization spectrum. The Fund may trade securities actively.

11​

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.

Foreign Investments Risk −Investments in foreign securities may be riskier than investments in U.S. securities. Differences between the U.S. and foreign regulatory regimes and securities markets, including the less stringent investor protection 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. Certain European countries in which the Fund may invest have recently experienced significant volatility in financial markets and may continue to do so in the future. The impact of the United Kingdom’s intended departure from the European Union, commonly known as “Brexit,” and the potential departure of one or more other countries from the European Union may have significant political and financial consequences for global markets. This may adversely impact Fund performance.

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, less extensive and less frequent accounting, financial 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. 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.

Depositary Receipts Risk −The Fund may invest in securities of foreign issuers in the form of depositary receipts or other securities that are convertible into securities of foreign issuers, including depositary receipts that are not sponsored by a financial institution (“Unsponsored Depositary Receipts”). Depositary receipts are generally subject to the same risks as the foreign securities that they evidence or into which they may be converted. Unsponsored Depositary Receipts are also subject to the risk that there may be less information available regarding their issuers and there may not be a correlation between such information and the market value of the depositary receipts.

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 and other risks. 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.

Mid Cap and Small Cap Securities Risk −Investments in small capitalization and mid 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.

12

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.

Quantitative Investing Risk −The value of securities or other investments selected using quantitative analysis can perform differently from the market as a whole or from their expected performance. This may be as a result of the factors used in building the quantitative analytical framework, the weights placed on each factor, the accuracy of historical data supplied by third parties, and changing sources of market returns.

Active Trading Risk −Active trading could increase the Fund's transaction costs and may increase your tax liability as compared to a fund with less active trading policies. These effects may adversely affect Fund performance.

Securities Lending Risk −The Fund may engage in securities lending. The Fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

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

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.

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.

Such tax-deferred arrangements may be taxed later upon withdrawal of monies from those arrangements.

PAYMENTS TO BROKER-DEALERS AND OTHER FINANCIAL INTERMEDIARIES. If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank or financial advisor), the Fund and its related companies may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your financial advisor to recommend the Fund over another investment. Ask your financial advisor or visit your financial intermediary’s website for more information.

​

(4)

Hartford Funds Management Company, LLC (the “Investment Manager”) has contractually agreed to reimburse expenses (exclusive of taxes, interest expenses, brokerage commissions, acquired fund fees and expenses and extraordinary expenses) to the extent necessary to maintain total annual fund operating expenses as follows: 1.19% (Class A), 1.94% (Class C), 0.89% (Class I), 1.41% (Class R3), 1.11% (Class R4), 0.81% (Class R5), 0.69% (Class R6), 0.79% (Class Y), and 0.69% (Class F).

​

Your actual costs may be higher or lower. Based on these assumptions, you would pay the following expenses if you sell all of your shares at the end of each time period indicated:

You would pay the following expenses if you did not redeem your shares:

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 examples, affect the Fund’s performance. During the fiscal year ended October 31, 2019, the Fund’s portfolio turnover rate was [ ]% 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. Wellington Management Company LLP (“Wellington Management”), the Fund’s sub-adviser, seeks to invest the Fund’s assets in companies that focus their operations in areas that Wellington Management believes are likely to address major social and environmental challenges including, but not limited to, sustainable agriculture and nutrition, health, clean water and sanitation, affordable housing, education and job training, financial inclusion, narrowing the digital divide, alternative energy, resource stewardship, resource efficiency, and safety and security. 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 evaluates 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, including certain environmental, social and/or governance (ESG) factors. 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. 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,

17​

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.

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.

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 small capitalization and mid 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 than investments in U.S. securities. Differences between the U.S. and foreign regulatory regimes and securities markets, including the less stringent investor protection 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. Certain European countries in which the Fund may invest have recently experienced significant volatility in financial markets and may continue to do so in the future. The impact of the United Kingdom’s intended departure from the European Union, commonly known as “Brexit,” and the potential departure of one or more other countries from the European Union may have significant political and financial consequences for global markets. This may adversely impact Fund performance.

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, less extensive and less frequent accounting, financial 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. 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 intends to invest in companies whose core business seeks to address the world’s major social and environmental challenges. This investment focus may affect the Fund’s exposure to certain companies or industries and the Fund may forego certain investment opportunities. The Fund may underperform other funds that do not seek to invest in companies based on expected societal impact outcomes. Although the Fund seeks to identify companies that it believes seek to address major social and environmental challenges, investors may differ in their views of what constitutes such challenges. As a result, the Fund may invest in companies that do not reflect the beliefs and values of any particular investor.

18

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.

Securities Lending Risk −The Fund may engage in securities lending. The Fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

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.

PAYMENTS TO BROKER-DEALERS AND OTHER FINANCIAL INTERMEDIARIES. If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank or financial advisor), the Fund and its related companies may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your financial advisor to recommend the Fund over another investment. Ask your financial advisor or visit your financial intermediary’s website for more information.

Your actual costs may be higher or lower. Based on these assumptions, you would pay the following expenses if you sell all of your shares at the end of each time period indicated:

You would pay the following expenses if you did not redeem your shares:

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 examples, affect the Fund’s performance. During the fiscal year ended October 31, 2019, the Fund’s portfolio turnover rate was [ ]% of the average value of its portfolio.

Principal Investment Strategy. The Fund seeks to achieve its investment objective by investing at least 65% of its net assets in foreign equity securities. Under normal circumstances, the Fund invests at least 80% of its assets in equity securities or equity-related securities, including derivative investments that provide exposure to equity securities. The Fund seeks to outperform the MSCI All Country World (ACWI) ex USA Index. The Fund diversifies its investments among a broad range of companies in a number of different countries throughout the world, with no limit on the amount of assets that may be invested in each country. Securities in which the Fund invests are denominated in both U.S. dollars and foreign currencies and may trade in both U.S. and foreign markets. 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. The Fund may invest in companies of any market capitalization, and may trade securities actively.

The Fund seeks its investment objective by employing a multiple sleeve structure, which means the Fund has several components that the sub-adviser, Wellington Management Company LLP (“Wellington Management”), manages using different investment styles. Each component sleeve has a distinct investment philosophy and analytical process to identify specific securities for purchase or sale. Each of these sleeves is managed independently of each other. Wellington Management also may allocate a portion of the Fund’s assets in securities that Wellington Management believes may complement the risk factor biases of the other sleeves (“Risk Managed Sleeve”) and selects such

23​

securities using systematic screening methodologies. Wellington Management does not allocate a set percentage to any specific sleeve but instead seeks a flexible and diversified Fund profile. Together the strategies represent a wide range of investment philosophies that are intended to be complementary to each other, companies, industries, and market capitalizations.

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.

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, less extensive and less frequent accounting, financial 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. 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 and other risks. 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.

Mid Cap and Small Cap Securities Risk −Investments in small capitalization and mid 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.

24

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.

Asset Allocation Risk −The risk that if the Fund’s strategy for allocating assets among different portfolio management teams does not work as intended, the Fund may not achieve its objective or may underperform other funds with similar investment strategies. The investment styles employed by the portfolio managers may not be complementary, which could adversely affect the performance of the Fund.

Quantitative Investing Risk −The value of securities or other investments selected using quantitative analysis can perform differently from the market as a whole or from their expected performance. This may be as a result of the factors used in building the quantitative analytical framework, the weights placed on each factor, the accuracy of historical data supplied by third parties, and changing sources of market returns.

Securities Lending Risk −The Fund may engage in securities lending. The Fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Active Trading Risk −Active trading could increase the Fund's transaction costs and may increase your tax liability as compared to a fund with less active trading policies. These effects may adversely affect Fund 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.
