China Risk – Investing in securities of Chinese issuers involves certain risks and considerations not typically associated with investing in securities of U.S. issuers, including, among others, more frequent trading suspensions

and government interventions (including by nationalization of assets), currency exchange rate fluctuations or blockages, limits on the use of brokers and on foreign ownership, different financial reporting standards, higher dependence on exports and international trade, potential for increased trade tariffs, sanctions, embargoes and other trade limitations, custody risks, risks associated with investments in variable interest entities, and potential adverse tax consequences. U.S. sanctions or other investment restrictions could preclude the Fund from investing in certain Chinese issuers or cause the Fund to sell investments at a disadvantageous time. Significant portions of the Chinese securities markets may become rapidly illiquid, as Chinese issuers have the ability to suspend the trading of their equity securities, and have shown a willingness to exercise that option in response to market volatility and other events.

—

Investment Style Risk – Baillie Gifford Overseas Limited (the “Manager”) actively makes investment decisions for the Fund through bottom-up stock selection. Accordingly, the Fund will have risk characteristics that differ from its benchmark index. The Manager’s judgments about the attractiveness, relative value, or potential appreciation of a particular stock may prove to be incorrect and cause the Fund to lose money or underperform compared to its benchmark index. There can be no assurance that the Manager’s investment decisions will produce the desired results.

Risk [Text Block]

—

Government and Regulatory Risk – Governmental and regulatory authorities in the United States and other countries, have taken, and may in the future take, actions intervening in the markets in which the Fund invests and in the economy more generally. Governmental and regulatory authorities may also act to increase the scope or burden of regulations applicable to the Fund or to the companies in which the Fund invests. The effects of these actions on the markets generally, and the Fund’s investment program in particular, can be uncertain and could restrict the ability of the Fund to fully implement its investment strategies, either generally, or with respect to certain securities, industries, or countries. By contrast, markets in some non-U.S. countries historically have been subject to little regulation or oversight by governmental or regulatory authorities, which could heighten the risk of loss due to fraud or market failures in those countries. Governments, agencies, or other regulatory bodies in any country may adopt or change laws or regulations that could adversely affect the Fund or the market value of an instrument held by the Fund.

Risk [Text Block]

—

Market Disruption and Geopolitical Risk – The value of the Fund’s investments could be adversely affected by events that disrupt securities markets and adversely affect global markets such as war, terrorism, public health crises, and geopolitical events and by changes in non-U.S. and U.S. economic and political conditions. These disruptions could prevent the Fund from implementing its investment strategies and achieving its investment objective, and increase the Fund’s exposure to other risks detailed in this Prospectus. As a result, the Fund could lose money, experience significant redemptions, encounter operational difficulties,

and suffer other negative impacts. Certain locations and industries may be particularly susceptible to this risk, and other risks may be heightened by such events.

Baillie Gifford China Equities Fund - Institutional & K Class Prospectus | Baillie Gifford China Equities Fund | Geographic Focus Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

—

Geographic Focus Risk – The Fund expects to focus its investments in a limited number of countries or geographic regions, and as a result may not offer the same level of diversification of risks as a more broadly global fund because the Fund will be exposed to a smaller geographic area. The performance of a fund that is less diversified across countries or geographic regions will be closely tied to market, currency, economic, political, environmental, or regulatory conditions and developments in the countries or regions in which the Fund invests, and may be more volatile than the performance of a more geographically-diversified portfolio.

Baillie Gifford China Equities Fund - Institutional & K Class Prospectus | Baillie Gifford China Equities Fund | Conflicts of Interest Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

—

Conflicts of Interest Risk – The Manager’s relationships with the Fund’s institutional investor base may give rise to various conflicts of interest, since the Manager will sometimes have an incentive to favor those shareholders over other shareholders in the Fund. In addition, the Manager serves as investment adviser to various clients other than the Fund, some of whom may pursue strategies that are substantially similar or nearly identical to investment strategies pursued by the Fund. This “side-by-side” management may give rise to various conflicts of interest, including, for example, in connection with the fair allocation of trades among the Manager’s clients or the sharing of different, more, or more timely information regarding investment performance, portfolio holdings, strategy developments and/or the Manager’s general market outlook. Furthermore, if investment personnel of the Manager hold board or other positions at outside companies, they could be exposed to material non-public information potentially impeding or delaying the Fund’s ability to buy or sell certain investments, or they could otherwise be restricted in their ability to participate in the Fund’s investment process.

Baillie Gifford China Equities Fund - Institutional & K Class Prospectus | Baillie Gifford China Equities Fund | Currency Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

—

Currency Risk – The Fund may realize a loss if it has exposure to a non-U.S. currency, and this non-U.S. currency declines in value, relative to the U.S. dollar. The Fund does not expect to engage in currency hedging and thus expects to be fully exposed to currency fluctuations relative to the U.S. dollar.

Emerging Markets Risk – To the extent the Fund invests in emerging market securities, the Fund may be exposed to greater market, credit, currency, liquidity, legal, political, technical and other risks different from, or greater than, the risks of investing in developed markets.

—

Equity Securities Risk – Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer. Investing in equity securities indirectly, such as through participatory notes or depositary receipts, may involve other risks such as the risk that the counterparty may default or that the investment does not track the underlying security as expected.

Baillie Gifford China Equities Fund - Institutional & K Class Prospectus | Baillie Gifford China Equities Fund | ESG Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

—

ESG Risk – To the extent that the Fund’s portfolio managers incorporate environmental, social and/or governance

considerations (“ESG Factors”) into the Fund’s investment process as a part of the Fund’s long-term investment approach, the Fund is subject to the risk that it may underperform funds that do not take ESG Factors into account. The consideration of ESG Factors may prioritize long-term rather than short-term returns, and therefore may negatively impact the relative performance of the Fund over the short, medium or even long term depending on how successfully those ESG Factors are incorporated and whether such investments are in or out of favor. In considering ESG Factors, the portfolio managers may be dependent upon information and data obtained through voluntary reporting by issuers or third-party research that may be incomplete, inaccurate or unavailable, which could impact the portfolio managers’ assessment of relative risks and opportunities. See also “Long-Term Investment Strategy Risk” and “Selected Investment Techniques and Topics – Our Stewardship Approach.”

Focused Investment Risk – Because the Fund focuses its investments in a limited number of companies, its investment strategy could result in more risk or greater volatility in returns than if the Fund’s investments were less focused.

Growth Stock Risk – The prices of growth stocks may be based largely on expectations of future earnings, and their prices can decline rapidly and significantly in reaction to negative news. Growth stocks may underperform stocks in other broad style categories (and the stock market as a whole) over any period of time and may shift in and out of favor with investors generally, sometimes rapidly, depending on changes in market, economic, and other factors.

Information Technology Risk – Cyber-attacks, disruptions, or failures that affect the Fund’s service providers, counterparties, the securities markets generally, other market participants, or issuers of securities held by the Fund may adversely affect the Fund and its shareholders, including by causing losses for the Fund or impairing Fund operations.

Baillie Gifford China Equities Fund - Institutional & K Class Prospectus | Baillie Gifford China Equities Fund | IPO Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

—

IPO Risk – The Fund may purchase securities in IPOs. These securities are subject to many of the same risks of investing in companies with smaller market capitalizations. Securities issued in IPOs have no trading history, and information about the companies may be available for very limited periods. In addition, the prices of securities sold in IPOs may be highly volatile.

Baillie Gifford China Equities Fund - Institutional & K Class Prospectus | Baillie Gifford China Equities Fund | Large-Capitalization Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

—

Large-Capitalization Securities Risk – Returns on investments in securities of large companies could trail the returns on investments in securities of smaller and medium-sized companies. Larger companies may be unable to respond as quickly as smaller and medium-sized companies to competitive challenges or to changes in business, product, financial, or other market conditions. Larger companies may not be able to achieve or maintain growth at the high rates that may be achieved by well-managed smaller and medium-sized companies.

Baillie Gifford China Equities Fund - Institutional & K Class Prospectus | Baillie Gifford China Equities Fund | Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

—

Liquidity Risk – The Fund’s investments may be subject to low trading volume, lack of a market maker, contractual lock-in periods or regulatory restrictions, and the Fund may hold large positions in particular securities. As a result, it may not be possible to sell an investment at a particular time or at an acceptable price. Liquidity risk may be magnified during periods of changing interest rates, significant shareholder redemptions or market turmoil. Illiquid investments may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value. In some cases, due to unanticipated levels of illiquidity the Fund may seek to meet its redemption obligations wholly or in part by distributions of assets in-kind.

Baillie Gifford China Equities Fund - Institutional & K Class Prospectus | Baillie Gifford China Equities Fund | Long-Term Investment Strategy Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

—

Long-Term Investment Strategy Risk – The Fund pursues a long-term investment approach, typically seeking returns over a period of several years. This investment style may cause the Fund to lose money or underperform compared to its benchmark index or other mutual funds over extended periods of time, and the Fund may not perform as expected in the long term. An investment in the Fund may be more suitable for long-term investors who can bear the risk of short- or medium-term fluctuations in the value of the Fund’s portfolio. See also “Selected Investment Techniques and Topics – Our Stewardship Approach.”

Market Risk – The value of the Fund’s investments will be affected by fluctuations in the stock markets in which the Fund is invested, factors affecting a particular industry or industries, real or perceived adverse economic conditions, changes in interest or currency rates or adverse investor sentiment generally. Declines in securities market prices may reduce the net asset value of the Fund’s shares.

Prospectus [Line Items]  
Risk [Text Block]

—

New and Smaller-Sized Funds Risk – New funds and smaller-sized funds, such as the Fund, will be subject to greater liquidity risk due to their smaller asset bases and may be required to sell securities at disadvantageous times or prices due to a large shareholder redemption. A fund that has been recently formed will have limited or no performance history for investors to evaluate and may not reach or maintain a sufficient asset size to effectively implement its investment strategy.

Baillie Gifford China Equities Fund - Institutional & K Class Prospectus | Baillie Gifford China Equities Fund | Non-Diversification Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

—

Non-Diversification Risk – The Fund is classified as a “non-diversified” fund. A non-diversified fund may hold a smaller number of portfolio securities, with larger positions in each security it holds, than many other mutual funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund’s shares may be more volatile than the values of shares of more diversified funds. See also “Focused Investment Risk.”

—

Non-U.S. Investment Risk – Non-U.S. securities are subject to additional risks, including less liquidity, increased volatility, less transparency, withholding or other taxes, increased vulnerability to adverse changes in local and global economic conditions, less regulation, and possible fluctuation in value due to adverse political conditions. Foreign portfolio transactions generally involve higher

commission rates, transfer taxes, and custodial costs than similar transactions in the U.S.

Service Provider Risk – The Fund will be affected by the Manager’s investment techniques, analyses, assessments and employee retention. Similarly, adverse events or performance failures at a service provider, such as human error, inadequate controls or insolvency, have the ability to adversely affect the Fund.

Baillie Gifford China Equities Fund - Institutional & K Class Prospectus | Baillie Gifford China Equities Fund | Settlement Risk [Member]

Risk [Text Block]

—

Settlement Risk – The Fund may experience delays in settlement due to the different clearance and settlement procedures in non-U.S. countries. Such delays may increase credit risk to the Fund, limit the ability of the Fund to reinvest the proceeds of a sale of securities, or prevent the Fund from selling securities at times and prices it considers desirable.

Risk [Text Block]

—

Small- and Medium-Capitalization Securities Risk – Securities of small- and medium-capitalization companies can be more volatile due to various factors including more limited product lines, financial and management resources and market distribution channels, as well as shorter operating histories and potentially reduced liquidity, especially during market declines, than the securities of larger, more established companies.

Baillie Gifford China Equities Fund - Institutional & K Class Prospectus | Baillie Gifford China Equities Fund | Underlying Funds Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

—

Underlying Funds Risk – Investments in other pooled investment vehicles may indirectly expose the Fund to all of the risks applicable to an investment in such other pooled vehicle. The Fund must pay its pro rata portion of the other pooled vehicle’s fees and expenses. If such pooled vehicle is an ETF or other product traded on a securities exchange or otherwise actively traded, its shares may trade at a premium or discount to their net asset value, an effect that might be more pronounced in less liquid markets. Further, the Manager or an affiliate may serve as investment adviser to some pooled vehicles in which the Fund invests, leading to potential conflicts of interest.

Baillie Gifford China Equities Fund - Institutional & K Class Prospectus | Baillie Gifford China Equities Fund | Valuation Risk [Member]

Risk [Text Block]

—

Valuation Risk – In certain circumstances, some of the Fund’s portfolio holdings may be valued on the basis of factors other than market quotations by employing fair value procedures. This may occur more often in times of market turmoil or reduced liquidity. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. There is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time.

Asia Risk – Investing in securities of companies located in or with exposure to Asian countries involves certain risks and considerations not typically associated with investing in securities of U.S. issuers, including different financial reporting standards, currency exchange rate fluctuations, and highly regulated markets with the potential for government interference. The economies of many Asian countries are heavily dependent on international trade and on only a few industries or commodities and, as a result, can be adversely affected by trade barriers, exchange controls and other measures imposed or negotiated by the countries with which they trade. Some Asian securities may be less liquid than U.S. or other foreign securities. See “China Risk” for additional details regarding the risks of investing in that country.

Additionally, many of the economies of countries in Asia are considered emerging market or frontier market economies. These Asian economies are often characterized by high inflation, undeveloped financial service sectors, frequent currency fluctuations, devaluations, or restrictions, political and social instability, and less efficient markets. See “Emerging Markets Risk” and “Frontier Markets Risk” for additional details regarding the risks of investing in such countries.

Conflicts of Interest Risk – The Manager’s relationships with the Fund’s institutional investor base may give rise to various conflicts of interest, since the Manager will sometimes have

an incentive to favor those shareholders over other shareholders in the Fund. In addition, the Manager serves as investment adviser to various clients other than the Fund, some of whom may pursue strategies that are substantially similar or nearly identical to investment strategies pursued by the Fund. This “side-by-side” management may give rise to various conflicts of interest, including, for example, in connection with the fair allocation of trades among the Manager’s clients or the sharing of different, more, or more timely information regarding investment performance, portfolio holdings, strategy developments and/or the Manager’s general market outlook. Although the Fund’s investment objective and strategies are substantially similar to those of an ETF managed by the Manager, differences in purchase and redemption structure, investment restrictions, and legal requirements lead to the use of different trading practices and potentially different portfolio decisions. Furthermore, if investment personnel of the Manager hold board or other positions at outside companies, they could be exposed to material non-public information potentially impeding or delaying the Fund’s ability to buy or sell certain investments, or they could otherwise be restricted in their ability to participate in the Fund’s investment process.

ESG Risk – To the extent that the Fund’s portfolio managers incorporate environmental, social and/or governance considerations (“ESG Factors”) into the Fund’s investment process as a part of the Fund’s long-term investment approach, the Fund is subject to the risk that it may underperform funds that do not take ESG Factors into account. The consideration of ESG Factors may prioritize long-term rather than short-term returns, and therefore may negatively impact the relative performance of the Fund over the short, medium or even long term depending on how successfully those ESG Factors are incorporated and whether such investments are in or out of favor. In considering ESG Factors, the portfolio managers may be dependent upon information and data obtained through voluntary reporting by issuers or third-party research that may be incomplete, inaccurate or unavailable, which could impact the portfolio managers’ assessment of relative risks and opportunities.

An investment in the Fund may be more suitable for long-term investors who can bear the risk of short- or medium-term fluctuations in the value of the Fund’s portfolio.

Market Risk – The value of the Fund’s investments will be affected by fluctuations in the stock markets in which the Fund is invested, factors affecting a particular industry or industries, real or perceived adverse economic conditions, changes in interest or currency rates or adverse investor sentiment generally. Declines in securities market prices may reduce the net asset value of the Fund’s shares.

Non-U.S. Investment Risk – Non-U.S. securities are subject to additional risks, including less liquidity, increased volatility, less transparency, withholding or other taxes, increased vulnerability to adverse changes in local and global economic conditions, less regulation, and possible fluctuation in value due to adverse political conditions. Foreign portfolio transactions generally involve higher commission rates, transfer taxes, and custodial costs than similar transactions in the U.S.

Small- and Medium-Capitalization Securities Risk – Securities of small- and medium-capitalization companies can be more volatile due to various factors including more limited product lines, financial and management resources and market distribution channels, as well as shorter operating histories and potentially reduced liquidity, especially during market declines, than the securities of larger, more established companies.

Underlying Funds Risk – Investments in other pooled investment vehicles may indirectly expose the Fund to all of the risks applicable to an investment in such other pooled

vehicle. The Fund must pay its pro rata portion of the other pooled vehicle’s fees and expenses. If such pooled vehicle is an ETF or other product traded on a securities exchange or otherwise actively traded, its shares may trade at a premium or discount to their net asset value, an effect that might be more pronounced in less liquid markets. Further, the Manager or an affiliate may serve as investment adviser to some pooled vehicles in which the Fund invests, leading to potential conflicts of interest.

Valuation Risk – In certain circumstances, some of the Fund’s portfolio holdings may be valued on the basis of factors other than market quotations by employing fair value procedures. This may occur more often in times of market turmoil or reduced liquidity. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. There is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time.

Investment Style Risk – Baillie Gifford Overseas Limited (the “Manager”) actively makes investment decisions for the Fund through bottom-up stock selection. Accordingly, the Fund will have risk characteristics that differ from its benchmark index.

Government and Regulatory Risk – Governmental and regulatory authorities in the United States and other countries, have taken, and may in the future take, actions intervening in the markets in which the Fund invests and in the economy more generally. Governmental and regulatory authorities may also act to increase the scope or burden of regulations applicable to the Fund or to the companies in which the Fund invests. The effects of these actions on the markets generally, and the Fund’s investment program in particular, can be uncertain and could restrict the ability of the Fund to fully implement its investment strategies, either generally, or with respect to certain securities, industries, or countries. By contrast, markets in some non-U.S. countries historically have been subject to little regulation or oversight by governmental or regulatory authorities, which could heighten the risk of loss due to fraud or market failures in those countries. Governments, agencies, or other regulatory bodies in any country may adopt or change laws or regulations that could adversely affect the Fund or the market value of an instrument held by the Fund.

Asia Risk – Investing in securities of companies located in or with exposure to Asian countries involves certain risks and considerations not typically associated with investing in securities of U.S. issuers, including different financial reporting standards, currency exchange rate fluctuations, and highly regulated markets with the potential for government interference. The economies of many Asian countries are heavily dependent on international trade and on only a few industries or commodities and, as a result, can be adversely affected by trade barriers, exchange controls and other measures imposed or negotiated by the countries with which they trade. Some Asian securities may be less liquid than U.S. or other foreign securities.

Additionally, many of the economies of countries in Asia are considered emerging market or frontier market economies. These Asian economies are often characterized by high inflation, undeveloped financial service sectors, frequent currency fluctuations, devaluations, or restrictions, political and social instability, and less efficient markets. See “Emerging Markets Risk” and “Frontier Markets Risk” for additional details regarding the risks of investing in such countries.

Market Disruption and Geopolitical Risk – The value of the Fund’s investments could be adversely affected by events that disrupt securities markets and adversely affect global markets such as war, terrorism, public health crises, and geopolitical events and by changes in non-U.S. and U.S. economic and political conditions. These disruptions could prevent the Fund from implementing its investment strategies and achieving its investment objective, and increase the Fund’s exposure to other risks detailed in this Prospectus. As a result, the Fund could lose money, experience significant redemptions, encounter operational difficulties, and suffer other negative impacts. Certain locations and industries may be particularly susceptible to this risk, and other risks may be heightened by such events.

—

Geographic Focus Risk – The Fund expects to focus its investments in a limited number of countries or geographic regions, and as a result may not offer the same level of diversification of risks as a more broadly global fund because the Fund will be exposed to a smaller geographic area. The performance of a fund that is less diversified across countries or geographic regions will be closely tied to market, currency, economic, political, environmental, or regulatory conditions and developments in the countries or regions in which the Fund invests, and may be more volatile than the performance of a more geographically-diversified portfolio.

Risk [Text Block]

—

Conflicts of Interest Risk – The Manager’s relationships with the Fund’s institutional investor base may give rise to various conflicts of interest, since the Manager will sometimes have an incentive to favor those shareholders over other shareholders in the Fund. In addition, the Manager serves as investment adviser to various clients other than the Fund, some of whom may pursue strategies that are substantially similar or nearly identical to investment strategies pursued by the Fund. This “side-by-side” management may give rise to various conflicts of interest, including, for example, in connection with the fair allocation of trades among the Manager’s clients or the sharing of different, more, or more timely information regarding investment performance, portfolio holdings, strategy developments and/or the Manager’s general market outlook. Furthermore, if investment personnel of the Manager hold board or other positions at outside companies, they could be exposed to material non-public information potentially impeding or delaying a Fund’s ability to buy or sell certain investments, or they could otherwise be restricted in their ability to participate in a Fund’s investment process.

ESG Risk – To the extent that the Fund’s portfolio managers incorporate environmental, social and/or governance considerations (“ESG Factors”) into the Fund’s investment process as a part of the Fund’s long-term investment approach, the Fund is subject to the risk that it may underperform funds that do not take ESG Factors into account. The consideration of ESG Factors may prioritize long-term rather than short-term returns, and therefore may negatively impact the relative performance of the Fund over the short, medium or even long term depending on how successfully those ESG Factors are incorporated and whether such investments are in or out of favor. In considering ESG Factors, the portfolio managers may be dependent upon information and data obtained through voluntary reporting by issuers or third-party research that

may be incomplete, inaccurate or unavailable, which could impact the portfolio managers’ assessment of relative risks and opportunities. See also “Long-Term Investment Strategy Risk” and “Selected Investment Techniques and Topics—Our Stewardship Approach.”

Larger companies may not be able to achieve or maintain growth at the high rates that may be achieved by well-managed smaller and medium-sized companies.

Liquidity Risk – The Fund’s investments may be subject to low trading volume, lack of a market maker, contractual lock-in periods or regulatory restrictions, and the Fund may hold large positions in particular securities. As a result, it may not be possible to sell an investment at a particular time or at an acceptable price. Liquidity risk may be magnified during

periods of changing interest rates, significant shareholder redemptions or market turmoil. Illiquid investments may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value. In some cases, due to unanticipated levels of illiquidity the Fund may seek to meet its redemption obligations wholly or in part by distributions of assets in-kind.

Long-Term Investment Strategy Risk – The Fund pursues a long-term investment approach, typically seeking returns over a period of several years, which can comprise a full market cycle or more. This investment style may cause the Fund to lose money or underperform compared to its benchmark index or other mutual funds over extended periods of time, and the Fund may not perform as expected in the long term. The market price of the Fund’s investments will fluctuate daily due to economic and other events that affect particular companies and other issuers or the market as a whole, and the market may disagree with the Manager’s assessment for growth in the shorter- or longer-terms. Short- and medium-term price fluctuations may be especially pronounced in less developed markets or in companies with lower market capitalizations.

Non-Diversification Risk – The Fund is classified as a “non-diversified” fund. A non-diversified fund may hold a smaller number of portfolio securities, with larger positions in each security it holds, than many other mutual funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund’s shares may be more volatile than the values of shares of more diversified funds. See also “Focused Investment Risk.”

China Risk – Investing in securities of Chinese issuers involves certain risks and considerations not typically associated with investing in securities of U.S. issuers, including, among others, more frequent trading suspensions and government interventions (including by nationalization of assets), currency exchange rate fluctuations or blockages, limits on the use of brokers and on foreign ownership, different financial reporting standards, higher dependence on exports and international trade, potential for increased trade tariffs, sanctions, embargoes and other trade limitations, custody risks, risks associated with investments in variable interest entities, and potential adverse tax consequences. U.S. sanctions or other investment restrictions could preclude the Fund from investing in certain Chinese issuers or cause the Fund to sell investments at a disadvantageous time. Significant portions of the Chinese securities markets may become rapidly illiquid, as Chinese issuers have the ability to suspend the trading of their equity securities, and have shown a willingness to exercise that option in response to market volatility and other events.

Developed Markets Risk – Investing in securities of companies located in, or with exposure to, developed countries will subject the Fund to the regulatory, political, currency, security, economic and other risks associated with such countries. In recent periods, countries with developed markets have generally experienced slower economic growth than some less developed countries. Services sectors (e.g., the financial services sector) generally tend to represent the primary source of economic growth in developed markets, which can make them susceptible to the risks of individual service sectors. In addition, developed countries will be impacted by changes to the economic conditions of certain key trading partners, regulatory burdens, and the price or availability of certain commodities, among other things.

Liquidity Risk – The Fund’s investments may be subject to low trading volume, lack of a market maker, contractual lock-in periods or regulatory restrictions, and the Fund may hold large positions in particular securities. As a result, it may not be possible to sell an investment at a particular time or at an acceptable price. Liquidity risk may be magnified during periods of changing interest rates, significant shareholder redemptions or market turmoil. Illiquid investments may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value. In some cases, due to unanticipated levels of illiquidity the Fund may seek to meet its redemption obligations wholly or in part by distributions of assets in-kind.

Long-Term Investment Strategy Risk – The Fund pursues a long-term investment approach, typically seeking returns over a period of several years. This investment style may cause the Fund to lose money or underperform compared to its benchmark index or other mutual funds over extended periods of time, and the Fund may not perform as expected in the long term. An investment in the Fund may be more suitable for long-term investors who can bear the risk of short- or medium-term fluctuations in the value of the Fund’s portfolio.

Valuation Risk – In certain circumstances, some of the Fund’s portfolio holdings may be valued on the basis of factors other than market quotations by employing fair value procedures. This may occur more often in times of market turmoil or reduced liquidity. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. There is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time.

China Risk – Investing in securities of Chinese issuers involves certain risks and considerations not typically associated with investing in securities of U.S. issuers, including, among others, more frequent trading suspensions and government interventions (including by nationalization of assets), currency exchange rate fluctuations or blockages, limits on the use of brokers and on foreign ownership, different financial reporting standards, higher dependence on exports and international trade, potential for increased trade tariffs, sanctions, embargoes and other trade limitations, custody risks, risks associated with investments in variable interest entities, and potential adverse tax consequences. U.S. sanctions or other investment restrictions could preclude the Fund from investing in certain Chinese issuers or cause the Fund to sell investments at a disadvantageous time. Significant portions of the Chinese securities markets may become rapidly illiquid, as Chinese issuers have the ability to suspend the trading of their equity securities, and have shown a willingness to exercise that option in response to market volatility and other events.

Investment Style Risk – Baillie Gifford Overseas Limited (the “Manager”) actively makes investment decisions for the Fund through bottom-up stock selection. Accordingly, the Fund will have risk characteristics that differ from its benchmark index. The Manager’s judgments about the attractiveness, relative value, or potential appreciation of a particular stock may prove to be incorrect and cause the Fund to lose money or underperform compared to its benchmark index. There can be no assurance that the Manager’s investment decisions will produce the desired results.

Government and Regulatory Risk – Governmental and regulatory authorities in the United States and other countries, have taken, and may in the future take, actions intervening in the markets in which the Fund invests and in the economy more generally. Governmental and regulatory authorities may also act to increase the scope or burden of regulations applicable to the Fund or to the companies in which the Fund invests. The effects of these actions on the markets generally, and the Fund’s investment program in particular, can be uncertain and could restrict the ability of the Fund to fully implement its investment strategies, either generally, or with respect to certain securities, industries, or countries. By contrast, markets in some non-U.S. countries historically have been subject to little regulation or oversight by governmental or regulatory authorities, which could heighten the risk of loss due to fraud or market failures in those countries. Governments, agencies, or other regulatory bodies in any country may adopt or change laws or regulations that could adversely affect the Fund or the market value of an instrument held by the Fund.

Asia Risk – Investing in securities of companies located in or with exposure to Asian countries involves certain risks and considerations not typically associated with investing in securities of U.S. issuers, including different financial reporting standards, currency exchange rate fluctuations, and highly regulated markets with the potential for government interference. The economies of many Asian

countries are heavily dependent on international trade and on only a few industries or commodities and, as a result, can be adversely affected by trade barriers, exchange controls and other measures imposed or negotiated by the countries with which they trade. Some Asian securities may be less liquid than U.S. or other foreign securities. See “China Risk” for additional details regarding the risks of investing in that country.

Additionally, many of the economies of countries in Asia are considered emerging market or frontier market economies. These Asian economies are often characterized by high inflation, undeveloped financial service sectors, frequent currency fluctuations, devaluations, or restrictions, political and social instability, and less efficient markets. See “Emerging Markets Risk” for additional details regarding the risks of investing in such countries.

Market Disruption and Geopolitical Risk – The value of the Fund’s investments could be adversely affected by events that disrupt securities markets and adversely affect global markets such as war, terrorism, public health crises, and geopolitical events and by changes in non-U.S. and U.S. economic and political conditions. These disruptions could prevent the Fund from implementing its investment strategies and achieving its investment objective, and increase the Fund’s exposure to other risks detailed in this Prospectus. As a result, the Fund could lose money, experience significant redemptions, encounter operational difficulties, and suffer other negative impacts. Certain locations and industries may be particularly susceptible to this risk, and other risks may be heightened by such events.

Geographic Focus Risk – The Fund expects to focus its investments in a limited number of countries or geographic regions, and as a result may not offer the same level of diversification of risks as a more broadly global fund because the Fund will be exposed to a smaller geographic area. The performance of a fund that is less diversified across countries or geographic regions will be closely tied to market, currency, economic, political, environmental, or regulatory conditions and developments in the countries or regions in which the Fund invests, and may be more volatile than the performance of a more geographically-diversified portfolio.

Risk [Text Block]

—

Conflicts of Interest Risk – The Manager’s relationships with the Fund’s institutional investor base may give rise to various conflicts of interest, since the Manager will sometimes have an incentive to favor those shareholders over other shareholders in the Fund. In addition, the Manager serves as investment adviser to various clients other than the Fund, some of whom may pursue strategies that are substantially similar or nearly identical to investment strategies pursued by the Fund. This “side-by-side” management may give rise to various conflicts of interest, including, for example, in connection with the fair allocation of trades among the Manager’s clients or the sharing of different, more, or more timely information regarding investment performance, portfolio holdings, strategy developments and/or the Manager’s general market outlook. Although the Fund’s investment objective and strategies are substantially similar to those of an ETF managed by the Manager, differences in purchase and redemption structure, investment restrictions, and legal requirements lead to the use of different trading practices and potentially different portfolio decisions. Furthermore, if investment personnel of the Manager hold board or other positions at outside companies, they could be exposed to material non-public information potentially

impeding or delaying the Fund’s ability to buy or sell certain investments, or they could otherwise be restricted in their ability to participate in the Fund’s investment process.

Currency Risk – The Fund may realize a loss if it has exposure to a non-U.S. currency, and this non-U.S. currency declines in value, relative to the U.S. dollar. The Fund does not expect to engage in currency hedging and thus expects to be fully exposed to currency fluctuations relative to the U.S. dollar.

Developed Markets Risk – Investing in securities of companies located in, or with exposure to, developed countries will subject the Fund to the regulatory, political, currency, security, economic and other risks associated with such countries. In recent periods, countries with developed markets have generally experienced slower economic growth than some less developed countries. Services sectors (e.g., the financial services sector) generally tend to represent the primary source of economic growth in developed markets, which can make them susceptible to the risks of individual service sectors. In addition, developed countries will be impacted by changes to the economic conditions of certain key trading partners, regulatory burdens, and the price or availability of certain commodities, among other things.

ESG Risk – To the extent that the Fund’s portfolio managers incorporate environmental, social and/or governance considerations (“ESG Factors”) into the Fund’s investment process as a part of the Fund’s long-term investment approach, the Fund is subject to the risk that it may underperform funds that do not take ESG Factors into account. The consideration of ESG Factors may prioritize long-term rather than short-term returns, and therefore may negatively impact the relative performance of the Fund over the short, medium or even long term depending on how successfully those ESG Factors are incorporated and whether such investments are in or out of favor. In considering ESG Factors, the portfolio managers may be dependent upon information and data obtained through voluntary reporting by issuers or third-party research that may be incomplete, inaccurate or unavailable, which could impact the portfolio managers’ assessment of relative risks and opportunities.

Currency Risk – The Fund may realize a loss if it has exposure to a non-U.S. currency, and this non-U.S. currency declines in value, relative to the U.S. dollar. The Fund does not expect to engage in currency hedging and thus expects to be fully exposed to currency fluctuations relative to the U.S. dollar.

Developed Markets Risk – Investing in securities of companies located in, or with exposure to, developed countries will subject the Fund to the regulatory, political, currency, security, economic and other risks associated with such countries. In recent periods, countries with developed markets have generally experienced slower economic growth than some less developed countries. Services sectors (e.g., the financial services sector) generally tend to represent the primary source of economic growth in developed markets, which can make them susceptible to the risks of individual service sectors. In addition, developed countries will be impacted by changes to the economic conditions of certain key trading partners, regulatory burdens, and the price or availability of certain commodities, among other things.

Equity Securities Risk – Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer. Investing in equity securities indirectly, such as through participatory notes or depositary receipts, may involve other risks such as the risk that the counterparty may default or that the investment does not track the underlying security as expected.

ESG Risk – To the extent that the Fund’s portfolio managers incorporate environmental, social and/or governance considerations (“ESG Factors”) into the Fund’s investment process as a part of the Fund’s long-term investment approach, the Fund is subject to the risk that it may underperform funds that do not take ESG Factors into account. The consideration of ESG Factors may prioritize

long-term rather than short-term returns, and therefore may negatively impact the relative performance of the Fund over the short, medium or even long term depending on how successfully those ESG Factors are incorporated and whether such investments are in or out of favor. In considering ESG Factors, the portfolio managers may be dependent upon information and data obtained through voluntary reporting by issuers or third-party research that may be incomplete, inaccurate or unavailable, which could impact the portfolio managers’ assessment of relative risks and opportunities.

Liquidity Risk – The Fund’s investments may be subject to low trading volume, lack of a market maker, contractual lock-in periods or regulatory restrictions, and the Fund may hold large positions in particular securities. As a result, it may not be possible to sell an investment at a particular time or at an acceptable price. Liquidity risk may be magnified during periods of changing interest rates, significant shareholder redemptions or market turmoil. Illiquid investments may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value. In some cases, due to unanticipated levels of illiquidity the Fund may seek to meet its redemption obligations wholly or in part by distributions of assets in-kind.

Long-Term Investment Strategy Risk – The Fund pursues a long-term investment approach, typically seeking returns over a period of several years. This investment style may cause the Fund to lose money or underperform compared to its benchmark index or other mutual funds over extended periods of time, and the Fund may not perform as expected in the long term. An investment in the Fund may be more suitable for long-term investors who can bear the risk of short- or medium-term fluctuations in the value of the Fund’s portfolio.

Non-Diversification Risk – The Fund is classified as a “non-diversified” fund.

Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. There is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time.

China Risk – Investing in securities of Chinese issuers involves certain risks and considerations not typically associated with investing in securities of U.S. issuers, including, among others, more frequent trading suspensions and government interventions (including by nationalization of assets), currency exchange rate fluctuations or blockages, limits on the use of brokers and on foreign ownership, different financial reporting standards, higher dependence on exports and international trade, potential for increased trade tariffs, sanctions, embargoes and other trade limitations, custody risks, risks associated with investments in variable interest entities, and potential adverse tax consequences. U.S. sanctions or other investment restrictions could preclude the Fund from investing in certain Chinese issuers or cause the Fund to sell investments at a disadvantageous time. Significant portions of the Chinese securities markets may become rapidly illiquid, as Chinese issuers have the ability to suspend the trading of their equity securities, and have shown a willingness to exercise that option in response to market volatility and other events.

Government and Regulatory Risk – Governmental and regulatory authorities in the United States and other countries, have taken, and may in the future take, actions intervening in the markets in which the Fund invests and in the economy more generally. Governmental and regulatory authorities may also act to increase the scope or burden of regulations applicable to the Fund or to the companies in which the Fund invests. The effects of these actions on the markets generally, and the Fund’s investment program in particular, can be uncertain and could restrict the ability of the Fund to fully implement its investment strategies, either generally, or with respect to certain securities, industries, or countries. By contrast, markets in some non-U.S. countries historically have been subject to little regulation or oversight by governmental or regulatory authorities, which could heighten the risk of loss due to fraud or market failures in those countries. Governments, agencies, or other regulatory bodies in any country may adopt or change laws or regulations that could adversely affect the Fund or the market value of an instrument held by the Fund.

Asia Risk – Investing in securities of companies located in or with exposure to Asian countries involves certain risks and considerations not typically associated with investing in securities of U.S. issuers, including different financial

reporting standards, currency exchange rate fluctuations, and highly regulated markets with the potential for government interference. The economies of many Asian countries are heavily dependent on international trade and on only a few industries or commodities and, as a result, can be adversely affected by trade barriers, exchange controls and other measures imposed or negotiated by the countries with which they trade. Some Asian securities may be less liquid than U.S. or other foreign securities. See “China Risk” for additional details regarding the risks of investing in that country.

Additionally, many of the economies of countries in Asia are considered emerging market or frontier market economies. These Asian economies are often characterized by high inflation, undeveloped financial service sectors, frequent currency fluctuations, devaluations, or restrictions, political and social instability, and less efficient markets. See “Emerging Markets Risk” for additional details regarding the risks of investing in such countries.

Market Disruption and Geopolitical Risk – The value of the Fund’s investments could be adversely affected by events that disrupt securities markets and adversely affect global markets such as war, terrorism, public health crises, and geopolitical events and by changes in non-U.S. and U.S. economic and political conditions. These disruptions could prevent the Fund from implementing its investment strategies and achieving its investment objective, and increase the Fund’s exposure to other risks detailed in this Prospectus. As a result, the Fund could lose money, experience significant redemptions, encounter operational difficulties, and suffer other negative impacts. Certain locations and industries may be particularly susceptible to this risk, and other risks may be heightened by such events.

Geographic Focus Risk – The Fund expects to focus its investments in a limited number of countries or geographic regions, and as a result may not offer the same level of diversification of risks as a more broadly global fund because the Fund will be exposed to a smaller geographic area. The performance of a fund that is less diversified across countries or geographic regions will be closely tied to market, currency, economic, political, environmental, or regulatory conditions and developments in the countries or regions in which the Fund invests, and may be more volatile than the performance of a more geographically-diversified portfolio.

Conflicts of Interest Risk – The Manager’s relationships with the Fund’s institutional investor base may give rise to various conflicts of interest, since the Manager will sometimes have an incentive to favor those shareholders over other shareholders in the Fund. In addition, the Manager serves as investment adviser to various clients other than the Fund, some of whom may pursue strategies that are substantially similar or nearly identical to investment strategies pursued by the Fund. This “side-by-side” management may give rise to various conflicts of interest, including, for example, in connection with the fair allocation of trades among the Manager’s clients or the sharing of different, more, or more timely information regarding investment performance, portfolio holdings, strategy developments and/or the Manager’s general market outlook. Furthermore, if investment personnel of the Manager hold board or other positions at outside companies, they could be exposed to material non-public information potentially impeding or delaying a Fund’s ability to buy or sell certain investments, or

they could otherwise be restricted in their ability to participate in a Fund’s investment process.

Services sectors (e.g., the financial services sector) generally tend to represent the primary source of economic growth in developed markets, which can make them susceptible to the risks of individual service sectors. In addition, developed countries will be impacted by changes to the economic conditions of certain key trading partners, regulatory burdens, and the price or availability of certain commodities, among other things.

Government and Regulatory Risk – Governmental and regulatory authorities in the United States and other countries, have taken, and may in the future take, actions intervening in the markets in which the Fund invests and in the economy more generally. Governmental and regulatory authorities may also act to increase the scope or burden of regulations applicable to the Fund or to the companies in

which the Fund invests. The effects of these actions on the markets generally, and the Fund’s investment program in particular, can be uncertain and could restrict the ability of the Fund to fully implement its investment strategies, either generally, or with respect to certain securities, industries, or countries. By contrast, markets in some non-U.S. countries historically have been subject to little regulation or oversight by governmental or regulatory authorities, which could heighten the risk of loss due to fraud or market failures in those countries. Governments, agencies, or other regulatory bodies in any country may adopt or change laws or regulations that could adversely affect the Fund or the market value of an instrument held by the Fund.

Asia Risk – Investing in securities of companies located in or with exposure to Asian countries involves certain risks and considerations not typically associated with investing in securities of U.S. issuers, including different financial reporting standards, currency exchange rate fluctuations, and highly regulated markets with the potential for government interference. The economies of many Asian countries are heavily dependent on international trade and on only a few industries or commodities and, as a result, can be adversely affected by trade barriers, exchange controls and other measures imposed or negotiated by the countries with which they trade. Some Asian securities may be less

liquid than U.S. or other foreign securities. See “China Risk” for additional details regarding the risks of investing in that country.

Additionally, many of the economies of countries in Asia are considered emerging market or frontier market economies. These Asian economies are often characterized by high inflation, undeveloped financial service sectors, frequent currency fluctuations, devaluations, or restrictions, political and social instability, and less efficient markets. See “Emerging Markets Risk” for additional details regarding the risks of investing in such countries.

Market Disruption and Geopolitical Risk – The value of the Fund’s investments could be adversely affected by events that disrupt securities markets and adversely affect global markets such as war, terrorism, public health crises, and geopolitical events and by changes in non-U.S. and U.S. economic and political conditions. These disruptions could prevent the Fund from implementing its investment strategies and achieving its investment objective, and increase the Fund’s exposure to other risks detailed in this Prospectus.

As a result, the Fund could lose money, experience significant redemptions, encounter operational difficulties, and suffer other negative impacts. Certain locations and industries may be particularly susceptible to this risk, and other risks may be heightened by such events.

Conflicts of Interest Risk – The Manager’s relationships with the Fund’s institutional investor base may give rise to various conflicts of interest, since the Manager will sometimes have an incentive to favor those shareholders over other shareholders in the Fund. In addition, the Manager serves as investment adviser to various clients other than the Fund, some of whom may pursue strategies that are substantially similar or nearly identical to investment strategies pursued by the Fund. This “side-by-side” management may give rise to various conflicts of interest, including, for example, in connection with the fair allocation of trades among the Manager’s clients or the sharing of different, more, or more timely information regarding investment performance, portfolio holdings, strategy developments and/or the Manager’s general market outlook. Furthermore, if investment personnel of the Manager hold board or other positions at outside companies, they could be exposed to material non-public information potentially impeding or delaying a Fund’s ability to buy or sell certain investments, or they could otherwise be restricted in their ability to participate in a Fund’s investment process.

Currency Risk – The Fund may realize a loss if it has exposure to a non-U.S. currency, and this non-U.S. currency declines in value, relative to the U.S. dollar. The Fund does not expect to engage in currency hedging and thus expects to be fully exposed to currency fluctuations relative to the U.S. dollar.

Developed Markets Risk – Investing in securities of companies located in, or with exposure to, developed countries will subject the Fund to the regulatory, political, currency, security, economic and other risks associated with such countries. In recent periods, countries with developed markets have generally experienced slower economic growth than some less developed countries. Services sectors (e.g., the financial services sector) generally tend to represent the primary source of economic growth in developed markets, which can make them susceptible to the risks of individual service sectors. In addition, developed countries will be impacted by changes to the economic conditions of certain key trading partners, regulatory burdens, and the price or availability of certain commodities, among other things.

ESG Risk – To the extent that the Fund’s portfolio managers incorporate environmental, social and/or governance considerations (“ESG Factors”) into the Fund’s investment process as a part of the Fund’s long-term investment approach, the Fund is subject to the risk that it may underperform funds that do not take ESG Factors into account. The consideration of ESG Factors may prioritize long-term rather than short-term returns, and therefore may negatively impact the relative performance of the Fund over the short, medium or even long term depending on how successfully those ESG Factors are incorporated and whether such investments are in or out of favor. In considering ESG Factors, the portfolio managers may be dependent upon information and data obtained through voluntary reporting by issuers or third-party research that may be incomplete, inaccurate or unavailable, which could impact the portfolio managers’ assessment of relative risks and opportunities.

As a result, it may not be possible to sell an investment at a particular time or at an acceptable price. Liquidity risk may be magnified during periods of changing interest rates, significant shareholder redemptions or market turmoil. Illiquid investments may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value. In some cases, due to unanticipated levels of illiquidity the Fund may seek to meet its redemption obligations wholly or in part by distributions of assets in-kind.

Long-Term Investment Strategy Risk – The Fund pursues a long-term investment approach, typically seeking returns over a period of several years. This investment style may cause the Fund to lose money or underperform compared to its benchmark index or other mutual funds over extended periods of time, and the Fund may not perform as expected in the long term. An investment in the Fund may be more suitable for long-term investors who can bear the risk of short- or medium-term fluctuations in the value of the Fund’s portfolio.

Non-Diversification Risk – The Fund is classified as a “non-diversified” fund. A non-diversified fund may hold a smaller number of portfolio securities, with larger positions in each security it holds, than many other mutual funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund’s shares may be more volatile than the values of shares of more diversified funds. See also “Focused Investment Risk.”

Valuation Risk – In certain circumstances, some of the Fund’s portfolio holdings may be valued on the basis of factors other than market quotations by employing fair value procedures. This may occur more often in times of market turmoil or reduced liquidity. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. There is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time.

Investment Style Risk – Baillie Gifford Overseas Limited (the “Manager”) actively makes investment decisions for the Fund through bottom-up stock selection. Accordingly, the Fund will have risk characteristics that differ from its benchmark index.

There can be no assurance that the Manager’s investment decisions will produce the desired results.

Geographic Focus Risk – The Fund expects to focus its investments in a limited number of countries or geographic regions, and as a result may not offer the same level of diversification of risks as a more broadly global fund because the Fund will be exposed to a smaller geographic area. The performance of a fund that is less diversified across countries or geographic regions will be closely tied to market, currency, economic, political, environmental, or regulatory conditions and developments in the countries or regions in which the Fund invests, and may be more volatile

than the performance of a more geographically-diversified portfolio.

China Risk – Investing in securities of Chinese issuers involves certain risks and considerations not typically associated with investing in securities of U.S. issuers, including, among others, more frequent trading suspensions and government interventions (including by nationalization of assets), currency exchange rate fluctuations or blockages, limits on the use of brokers and on foreign ownership, different financial reporting standards, higher dependence on exports and international trade, potential for increased trade tariffs, sanctions, embargoes and other trade limitations, custody risks, risks associated with investments in variable interest entities, and potential adverse tax consequences. U.S. sanctions or other investment restrictions could preclude the Fund from investing in certain Chinese issuers or cause the Fund to sell investments at a disadvantageous time. Significant portions of the Chinese securities markets may become rapidly illiquid, as Chinese issuers have the ability to suspend the trading of their equity securities, and have shown a willingness to exercise that option in response to market volatility and other events.

Investment Style Risk – Baillie Gifford Overseas Limited (the “Manager”) actively makes investment decisions for the Fund through bottom-up stock selection. Accordingly, the Fund will have risk characteristics that differ from its benchmark index. The Manager’s judgments about the attractiveness, relative value, or potential appreciation of a particular stock may prove to be incorrect and cause the Fund to lose money or underperform compared to its benchmark index. There can be no assurance that the Manager’s investment decisions will produce the desired results.

Government and Regulatory Risk – Governmental and regulatory authorities in the United States and other countries, have taken, and may in the future take, actions intervening in the markets in which the Fund invests and in the economy more generally. Governmental and regulatory authorities may also act to increase the scope or burden of regulations applicable to the Fund or to the companies in

which the Fund invests. The effects of these actions on the markets generally, and the Fund’s investment program in particular, can be uncertain and could restrict the ability of the Fund to fully implement its investment strategies, either generally, or with respect to certain securities, industries, or countries. By contrast, markets in some non-U.S. countries historically have been subject to little regulation or oversight by governmental or regulatory authorities, which could heighten the risk of loss due to fraud or market failures in those countries. Governments, agencies, or other regulatory bodies in any country may adopt or change laws or regulations that could adversely affect the Fund or the market value of an instrument held by the Fund.

Asia Risk – Investing in securities of companies located in or with exposure to Asian countries involves certain risks and considerations not typically associated with investing in securities of U.S. issuers, including different financial reporting standards, currency exchange rate fluctuations, and highly regulated markets with the potential for government interference. The economies of many Asian countries are heavily dependent on international trade and on only a few industries or commodities and, as a result, can be adversely affected by trade barriers, exchange controls and other measures imposed or negotiated by the countries with which they trade. Some Asian securities may be less liquid than U.S. or other foreign securities. See “China Risk” for additional details regarding the risks of investing in that country.

Additionally, many of the economies of countries in Asia are considered emerging market or frontier market economies. These Asian economies are often characterized by high inflation, undeveloped financial service sectors, frequent currency fluctuations, devaluations, or restrictions, political and social instability, and less efficient markets. See “Emerging Markets Risk” and “Frontier Markets Risk” for additional details regarding the risks of investing in such countries.

Market Disruption and Geopolitical Risk – The value of the Fund’s investments could be adversely affected by events that disrupt securities markets and adversely affect global markets such as war, terrorism, public health crises, and geopolitical events and by changes in non-U.S. and U.S. economic and political conditions. These disruptions could prevent the Fund from implementing its investment strategies and achieving its investment objective, and increase the Fund’s exposure to other risks detailed in this Prospectus. As a result, the Fund could lose money, experience significant redemptions, encounter operational difficulties, and suffer other negative impacts. Certain locations and industries may be particularly susceptible to this risk, and other risks may be heightened by such events.

Geographic Focus Risk – The Fund expects to focus its investments in a limited number of countries or geographic regions, and as a result may not offer the same level of diversification of risks as a more broadly global fund because the Fund will be exposed to a smaller geographic area. The performance of a fund that is less diversified across countries or geographic regions will be closely tied to market, currency, economic, political, environmental, or regulatory conditions and developments in the countries or regions in which the Fund invests, and may be more volatile than the performance of a more geographically-diversified portfolio.

Risk [Text Block]

—

Conflicts of Interest Risk – The Manager’s relationships with the Fund’s institutional investor base may give rise to various

conflicts of interest, since the Manager will sometimes have an incentive to favor those shareholders over other shareholders in the Fund. In addition, the Manager serves as investment adviser to various clients other than the Fund, some of whom may pursue strategies that are substantially similar or nearly identical to investment strategies pursued by the Fund. This “side-by-side” management may give rise to various conflicts of interest, including, for example, in connection with the fair allocation of trades among the Manager’s clients or the sharing of different, more, or more timely information regarding investment performance, portfolio holdings, strategy developments and/or the Manager’s general market outlook. Although the Fund’s investment objective and strategies are substantially similar to those of an ETF managed by the Manager, differences in purchase and redemption structure, investment restrictions, and legal requirements lead to the use of different trading practices and potentially different portfolio decisions. Furthermore, if investment personnel of the Manager hold board or other positions at outside companies, they could be exposed to material non-public information potentially impeding or delaying the Fund’s ability to buy or sell certain investments, or they could otherwise be restricted in their ability to participate in the Fund’s investment process.

Currency Risk – The Fund may realize a loss if it has exposure to a non-U.S. currency, and this non-U.S. currency declines in value, relative to the U.S. dollar. The Fund does not expect to engage in currency hedging and thus expects to be fully exposed to currency fluctuations relative to the U.S. dollar.

ESG Risk – To the extent that the Fund’s portfolio managers incorporate environmental, social and/or governance considerations (“ESG Factors”) into the Fund’s investment process as a part of the Fund’s long-term investment approach, the Fund is subject to the risk that it may underperform funds that do not take ESG Factors into account. The consideration of ESG Factors may prioritize long-term rather than short-term returns, and therefore may negatively impact the relative performance of the Fund over the short, medium or even long term depending on how successfully those ESG Factors are incorporated and whether such investments are in or out of favor. In considering ESG Factors, the portfolio managers may be dependent upon information and data obtained through voluntary reporting by issuers or third-party research that may be incomplete, inaccurate or unavailable, which could impact the portfolio managers’ assessment of relative risks and opportunities.

Liquidity Risk – The Fund’s investments may be subject to low trading volume, lack of a market maker, contractual lock-in periods or regulatory restrictions, and the Fund may hold large positions in particular securities. As a result, it may not be possible to sell an investment at a particular time or at an acceptable price. Liquidity risk may be magnified during periods of changing interest rates, significant shareholder redemptions or market turmoil. Illiquid investments may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value. In some cases, due to unanticipated levels of illiquidity the Fund may

seek to meet its redemption obligations wholly or in part by distributions of assets in-kind.

otherwise actively traded, its shares may trade at a premium or discount to their net asset value, an effect that might be more pronounced in less liquid markets. Further, the Manager or an affiliate may serve as investment adviser to some pooled vehicles in which the Fund invests, leading to potential conflicts of interest.

There is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time.

Developed market countries tend to represent a significant portion of the global economy and in recent periods, countries with developed markets have generally experienced slower economic growth than some less developed countries. Services sectors (e.g., the financial services sector) generally tend to represent the primary source of economic growth in developed markets, which can make them susceptible to the risks of individual service sectors. In addition, developed countries will be impacted by changes to the economic conditions of certain key trading partners, regulatory burdens, and the price or availability of certain commodities, among other things.

Non-U.S. Investment Risk – Non-U.S. securities are subject to additional risks, including less liquidity, increased volatility, less transparency, withholding or other taxes, increased vulnerability to adverse changes in local and global economic conditions, less regulation, and possible fluctuation in value due to adverse political conditions. Foreign portfolio transactions generally involve higher commission rates, transfer taxes, and custodial costs than similar transactions in the U.S.

Small- and Medium-Capitalization Securities Risk – Securities of small- and medium-capitalization companies can be more volatile due to various factors including more limited product lines, financial and management resources and market distribution channels, as well as shorter operating histories and potentially reduced liquidity, especially during market declines, than the securities of larger, more established companies.

Valuation Risk – In certain circumstances, some of the Fund’s portfolio holdings may be valued on the basis of factors other than market quotations by employing fair value procedures. This may occur more often in times of market turmoil or reduced liquidity. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. There is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time.

China Risk – Investing in securities of Chinese issuers involves certain risks and considerations not typically associated with investing in securities of U.S. issuers, including, among others, more frequent trading suspensions and government interventions (including by nationalization of assets), currency exchange rate fluctuations or blockages, limits on the use of brokers and on foreign ownership, different financial reporting standards, higher dependence on exports and international trade, potential for increased trade tariffs, sanctions, embargoes and other trade limitations, custody risks, risks associated with investments in variable interest entities, and potential adverse tax consequences. U.S. sanctions or other investment restrictions could preclude the Fund from investing in certain Chinese issuers or cause the Fund to sell investments at a disadvantageous time. Significant portions of the Chinese securities markets may become rapidly illiquid, as Chinese issuers have the ability to suspend the trading of their equity securities, and have shown a willingness to exercise that option in response to market volatility and other events.

Investment Style Risk – Baillie Gifford Overseas Limited (the “Manager”) actively makes investment decisions for the Fund through bottom-up stock selection. Accordingly, the Fund will have risk characteristics that differ from its benchmark index. The Manager’s judgments about the attractiveness, relative value, or potential appreciation of a particular stock may prove to be incorrect and cause the Fund to lose money or underperform compared to its benchmark index. There can be no assurance that the Manager’s investment decisions will produce the desired results.

Government and Regulatory Risk – Governmental and regulatory authorities in the United States and other countries, have taken, and may in the future take, actions intervening in the markets in which the Fund invests and in the economy more generally. Governmental and regulatory authorities may also act to increase the scope or burden of regulations applicable to the Fund or to the companies in which the Fund invests. The effects of these actions on the markets generally, and the Fund’s investment program in particular, can be uncertain and could restrict the ability of the Fund to fully implement its investment strategies, either generally, or with respect to certain securities, industries, or countries. By contrast, markets in some non-U.S. countries historically have been subject to little regulation or oversight by governmental or regulatory authorities, which could heighten the risk of loss due to fraud or market failures in those countries. Governments, agencies, or other regulatory bodies in any country may adopt or change laws or regulations that could adversely affect the Fund or the market value of an instrument held by the Fund.

Asia Risk – Investing in securities of companies located in or with exposure to Asian countries involves certain risks and considerations not typically associated with investing in securities of U.S. issuers, including different financial reporting standards, currency exchange rate fluctuations, and highly regulated markets with the potential for government interference. The economies of many Asian countries are heavily dependent on international trade and on only a few industries or commodities and, as a result, can be adversely affected by trade barriers, exchange controls

and other measures imposed or negotiated by the countries with which they trade. Some Asian securities may be less liquid than U.S. or other foreign securities. See “China Risk” for additional details regarding the risks of investing in that country.

Additionally, many of the economies of countries in Asia are considered emerging market or frontier market economies. These Asian economies are often characterized by high inflation, undeveloped financial service sectors, frequent currency fluctuations, devaluations, or restrictions, political and social instability, and less efficient markets. See “Emerging Markets Risk” for additional details regarding the risks of investing in such countries.

Market Disruption and Geopolitical Risk – The value of the Fund’s investments could be adversely affected by events that disrupt securities markets and adversely affect global markets such as war, terrorism, public health crises, and geopolitical events and by changes in non-U.S. and U.S. economic and political conditions. These disruptions could prevent the Fund from implementing its investment strategies and achieving its investment objective, and increase the Fund’s exposure to other risks detailed in this Prospectus. As a result, the Fund could lose money, experience significant redemptions, encounter operational difficulties, and suffer other negative impacts. Certain locations and industries may be particularly susceptible to this risk, and other risks may be heightened by such events.

—

Geographic Focus Risk – The Fund expects to focus its investments in a limited number of countries or geographic regions, and as a result may not offer the same level of diversification of risks as a more broadly global fund because the Fund will be exposed to a smaller geographic area. The performance of a fund that is less diversified across countries or geographic regions will be closely tied to market, currency, economic, political, environmental, or regulatory conditions and developments in the countries or regions in which the Fund invests, and may be more volatile than the performance of a more geographically-diversified portfolio.

Prospectus [Line Items]  
Risk [Text Block]

—

Conflicts of Interest Risk – The Manager’s relationships with the Fund’s institutional investor base may give rise to various conflicts of interest, since the Manager will sometimes have an incentive to favor those shareholders over other shareholders in the Fund. In addition, the Manager serves as investment adviser to various clients other than the Fund, some of whom may pursue strategies that are substantially similar or nearly identical to investment strategies pursued by the Fund. This “side-by-side” management may give rise to various conflicts of interest, including, for example, in connection with the fair allocation of trades among the Manager’s clients or the sharing of different, more, or more timely information regarding investment performance, portfolio holdings, strategy developments and/or the Manager’s general market outlook. Although the Fund’s investment objective and strategies are substantially similar to those of an ETF managed by the Manager, differences in purchase and redemption structure, investment restrictions, and legal requirements lead to the use of different trading practices and potentially different portfolio decisions. Furthermore, if investment personnel of the Manager hold board or other positions at outside companies, they could be exposed to material non-public information potentially impeding or delaying the Fund’s ability to buy or sell certain investments, or they could otherwise be restricted in their ability to participate in the Fund’s investment process.

Currency Risk – The Fund may realize a loss if it has exposure to a non-U.S. currency, and this non-U.S. currency declines in value, relative to the U.S. dollar. The Fund does not expect to engage in currency hedging and thus expects to be fully exposed to currency fluctuations relative to the U.S. dollar.

Developed Markets Risk – Investing in securities of companies located in, or with exposure to, developed countries will subject the Fund to the regulatory, political, currency, security, economic and other risks associated with such countries. In recent periods, countries with developed markets have generally experienced slower economic growth than some less developed countries. Services sectors (e.g., the financial services sector) generally tend to represent the primary source of economic growth in developed markets, which can make them susceptible to the risks of individual service sectors. In addition, developed countries will be impacted by changes to the economic conditions of certain key trading partners, regulatory burdens, and the price or availability of certain commodities, among other things.

ESG Risk – To the extent that the Fund’s portfolio managers incorporate environmental, social and/or governance considerations (“ESG Factors”) into the Fund’s investment process as a part of the Fund’s long-term investment approach, the Fund is subject to the risk that it may underperform funds that do not take ESG Factors into account. The consideration of ESG Factors may prioritize long-term rather than short-term returns, and therefore may negatively impact the relative performance of the Fund over the short, medium or even long term depending on how successfully those ESG Factors are incorporated and whether such investments are in or out of favor. In considering ESG Factors, the portfolio managers may be dependent upon information and data obtained through voluntary reporting by issuers or third-party research that may be incomplete, inaccurate or unavailable, which could impact the portfolio managers’ assessment of relative risks and opportunities.

Larger companies may

not be able to achieve or maintain growth at the high rates that may be achieved by well-managed smaller and medium-sized companies.

Liquidity Risk – The Fund’s investments may be subject to low trading volume, lack of a market maker, contractual lock-in periods or regulatory restrictions, and the Fund may hold large positions in particular securities. As a result, it may not be possible to sell an investment at a particular time or at an acceptable price. Liquidity risk may be magnified during periods of changing interest rates, significant shareholder redemptions or market turmoil. Illiquid investments may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value. In some cases, due to unanticipated levels of illiquidity the Fund may seek to meet its redemption obligations wholly or in part by distributions of assets in-kind.

The consideration of ESG Factors may prioritize long-term rather than short-term returns, and therefore may negatively impact the relative performance of the Fund over the short, medium or even long term depending on how successfully those ESG Factors are incorporated and whether such investments are in or out of favor. In considering ESG Factors, the portfolio managers may be dependent upon information and data obtained through voluntary reporting by issuers or third-party research that may be incomplete, inaccurate or unavailable, which could impact the portfolio managers’ assessment of relative risks and opportunities.

IPO Risk – The Fund may purchase securities in IPOs. These securities are subject to many of the same risks of investing in companies with smaller market capitalizations. Securities issued in IPOs have no trading history, and information about the companies may be available for very limited periods.

Liquidity Risk – The Fund’s investments may be subject to low trading volume, lack of a market maker, contractual lock-in periods or regulatory restrictions, and the Fund may hold large positions in particular securities. As a result, it may not be possible to sell an investment at a particular time or at an acceptable price. Liquidity risk may be magnified during periods of changing interest rates, significant shareholder redemptions or market turmoil. Illiquid investments may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value. In some cases, due to unanticipated levels of illiquidity the Fund may seek to meet its redemption obligations wholly or in part by distributions of assets in-kind.

Long-Term Investment Strategy Risk – The Fund pursues a long-term investment approach, typically seeking returns over a period of several years. This investment style may cause the Fund to lose money or underperform compared to its benchmark index or other mutual funds over extended periods of time, and the Fund may not perform as expected in the long term. An investment in the Fund may be more suitable for long-term investors who can bear the risk of short- or medium-term fluctuations in the value of the Fund’s portfolio.

Valuation Risk – In certain circumstances, some of the Fund’s portfolio holdings may be valued on the basis of factors other than market quotations by employing fair value procedures. This may occur more often in times of market turmoil or reduced liquidity. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. There is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time.

China Risk – Investing in securities of Chinese issuers involves certain risks and considerations not typically associated with investing in securities of U.S. issuers, including, among others, more frequent trading suspensions and government interventions (including by nationalization of assets), currency exchange rate fluctuations or blockages, limits on the use of brokers and on foreign ownership, different financial reporting standards, higher dependence on exports and international trade, potential for increased trade tariffs, sanctions, embargoes and other trade limitations, custody risks, risks associated with investments in variable interest entities, and potential adverse tax consequences. U.S. sanctions or other investment restrictions could preclude the Fund from investing in certain Chinese issuers or cause the Fund to sell investments at a disadvantageous time. Significant portions of the Chinese securities markets may become rapidly illiquid, as Chinese issuers have the ability to suspend the trading of their equity securities, and have shown a willingness to exercise that option in response to market volatility and other events.

Investment Style Risk – Baillie Gifford Overseas Limited (the “Manager”) actively makes investment decisions for the Fund through bottom-up stock selection. Accordingly, the Fund will have risk characteristics that differ from its benchmark index. The Manager’s judgments about the attractiveness, relative value, or potential appreciation of a particular stock may prove to be incorrect and cause the Fund to lose money or underperform compared to its benchmark index. There can be no assurance that the Manager’s investment decisions will produce the desired results.

Government and Regulatory Risk – Governmental and regulatory authorities in the United States and other countries, have taken, and may in the future take, actions intervening in the markets in which the Fund invests and in the economy more generally. Governmental and regulatory authorities may also act to increase the scope or burden of regulations applicable to the Fund or to the companies in which the Fund invests. The effects of these actions on the markets generally, and the Fund’s investment program in particular, can be uncertain and could restrict the ability of the Fund to fully implement its investment strategies, either generally, or with respect to certain securities, industries, or countries. By contrast, markets in some non-U.S. countries historically have been subject to little regulation or oversight by governmental or regulatory authorities, which could heighten the risk of loss due to fraud or market failures in those countries. Governments, agencies, or other regulatory bodies in any country may adopt or change laws or regulations that could adversely affect the Fund or the market value of an instrument held by the Fund.

Asia Risk – Investing in securities of companies located in or with exposure to Asian countries involves certain risks and

considerations not typically associated with investing in securities of U.S. issuers, including different financial reporting standards, currency exchange rate fluctuations, and highly regulated markets with the potential for government interference. The economies of many Asian countries are heavily dependent on international trade and on only a few industries or commodities and, as a result, can be adversely affected by trade barriers, exchange controls and other measures imposed or negotiated by the countries with which they trade. Some Asian securities may be less liquid than U.S. or other foreign securities. See “China Risk” for additional details regarding the risks of investing in that country.

Additionally, many of the economies of countries in Asia are considered emerging market or frontier market economies. These Asian economies are often characterized by high inflation, undeveloped financial service sectors, frequent currency fluctuations, devaluations, or restrictions, political and social instability, and less efficient markets. See “Emerging Markets Risk” for additional details regarding the risks of investing in such countries.

Market Disruption and Geopolitical Risk – The value of the Fund’s investments could be adversely affected by events that disrupt securities markets and adversely affect global markets such as war, terrorism, public health crises, and geopolitical events and by changes in non-U.S. and U.S. economic and political conditions. These disruptions could prevent the Fund from implementing its investment strategies and achieving its investment objective, and increase the Fund’s exposure to other risks detailed in this Prospectus. As a result, the Fund could lose money, experience significant redemptions, encounter operational difficulties, and suffer other negative impacts. Certain locations and industries may be particularly susceptible to this risk, and other risks may be heightened by such events.

Conflicts of Interest Risk – The Manager’s relationships with the Fund’s institutional investor base may give rise to various conflicts of interest, since the Manager will sometimes have an incentive to favor those shareholders over other shareholders in the Fund. In addition, the Manager serves as investment adviser to various clients other than the Fund, some of whom may pursue strategies that are substantially similar or nearly identical to investment strategies pursued by the Fund. This “side-by-side” management may give rise to various conflicts of interest, including, for example, in connection with the fair allocation of trades among the Manager’s clients or the sharing of different, more, or more timely information regarding investment performance, portfolio holdings, strategy developments and/or the Manager’s general market outlook. Furthermore, if investment personnel of the Manager hold board or other positions at outside companies, they could be exposed to material non-public information potentially impeding or

delaying a Fund’s ability to buy or sell certain investments, or they could otherwise be restricted in their ability to participate in a Fund’s investment process.

Currency Risk – The Fund may realize a loss if it has exposure to a non-U.S. currency, and this non-U.S. currency declines in value, relative to the U.S. dollar. The Fund does not expect to engage in currency hedging and thus expects to be fully exposed to currency fluctuations relative to the U.S. dollar.

Developed Markets Risk – Investing in securities of companies located in, or with exposure to, developed countries will subject the Fund to the regulatory, political, currency, security, economic and other risks associated with such countries. In recent periods, countries with developed markets have generally experienced slower economic growth than some less developed countries. Services sectors (e.g., the financial services sector) generally tend to represent the primary source of economic growth in developed markets, which can make them susceptible to the risks of individual service sectors. In addition, developed countries will be impacted by changes to the economic conditions of certain key trading partners, regulatory burdens, and the price or availability of certain commodities, among other things.
