The Fund invests by sampling the Target Indexes, meaning that it holds a range of securities that, in the aggregate, approximates the full Target Indexes in terms of key risk factors and other characteristics. Under normal circumstances, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in the securities that make up the Target Indexes and in securities that the advisor determines have substantially identical economic characteristics to the securities that make up the Target Indexes.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt;With approximately 60% of its assets, the Fund seeks to track the investment performance of the Equity Target Index, which represents approximately 100% of the investable U.S. stock market and includes large-,  mid-, small-, and micro-cap stocks.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt;With approximately 40% of its assets, the Fund seeks to track the investment performance of the Bond Target Index, which represents a wide spectrum of public, investment-grade, taxable, bonds in the United States&#x2014;including government, corporate, and international dollar-denominated bonds, as well as mortgage-backed and asset-backed securities&#x2014;all with maturities of more than 1 year.

Companies can be further classified into micro- or mega-cap. Different factors can affect each market cap uniquely, and historically small- and mid-cap stocks have typically been more volatile due to the effects of changing economic conditions. Large companies may not reach the same levels of growth or performance as smaller companies, and they may be slower to react to competitive challenges. The performance of funds that invest in a subset of market caps could diverge from the performance of a fund that is focused on a broader representation of the stock market.&lt;/span&gt;</oef:RiskTextBlock>

For example, as a general rule, bond prices and interest rates move in opposite directions. When interest rates rise, bond prices tend to fall, and when interest rates fall, bond prices tend to go up. Bond income also is affected by changes in interest rates. Interest rates can rise or fall for a number of reasons, including, but not limited to, central bank monetary policy, inflationary or deflationary pressures, and changes in general market and economic conditions. Changing interest rates, including, but not limited to, rates that fall below zero, could have unpredictable effects on the overall market and may expose the bond markets in particular to heightened volatility and potential illiquidity. The degree to which the Fund is impacted by certain bond market risks may vary based on factors disclosed in its principal investment strategies, such as the types of bonds in which it invests and the overall credit quality, average maturity, and/or average duration of its bond holdings.&lt;/span&gt;</oef:RiskTextBlock>

In addition, negative perceptions of an issuer&#x2019;s ability to make payments can cause the price of a security to decline.

Prepayment risk for callable bonds is described under &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;font-style:italic;font-weight:bold;"&gt;Call Risk&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;. With respect to mortgage-backed, asset-backed, and similar debt securities,  prepayment typically refers to borrowers repaying their debt early (e.g.,&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;before the maturity date).&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;Prepayment of bonds held by the Fund would result in the Fund losing any price appreciation above the amount repaid (or the bond&#x2019;s call price,&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;in the case of callable bonds). In addition, because prepayments occur more frequently in low interest rate environments, the Fund likely would be forced to reinvest the proceeds from any prepayments at a lower interest rate than when the prepaid bonds were purchased, resulting in a decline in the Fund&#x2019;s income and a potential loss in the value of the Fund&#x2019;s investments.

Because the Fund generally seeks to track the performance of the Target Index regardless of how the Target Index is performing, the Fund&#x2019;s performance may be lower than it would be if it were actively managed. Additionally,&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;because the Fund does not hold all of the securities included in the Target Index, it is subject to the risk that the representative sample of securities selected by the advisor will, in the aggregate, vary from the investment profile of the full Target Index. The performance of the Fund&#x2019;s investments,&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;in the aggregate,&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;may not match the investment performance of the Target Index. This risk, known as tracking error risk, may be heightened during times of increased market volatility or under other unusual market conditions. The Fund also could be negatively impacted by changes to the Target Index made by the index provider or by errors made by the index provider. Any gains, losses, or costs associated with or resulting from an error made by the index provider will generally be borne by the Fund and, as a result, the Fund&#x2019;s shareholders.&lt;/span&gt;</oef:RiskTextBlock>

Different parts of the market, including different industries and sectors as well as different types of securities, may react differently to factors that affect the market. These factors can contribute to market uncertainty,  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;margin-left:0.0pt;"&gt;market volatility, and fluctuations in the value of the &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;Fund&#x2019;s investments, thereby resulting&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:9.6pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;in potential losses to the Fund over short or long&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:9.6pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;periods.&lt;/span&gt;</oef:RiskTextBlock>

Companies can be further classified into micro- or mega-cap. Different factors can affect each market cap uniquely, and historically small- and mid-cap stocks have typically been more volatile due to the effects of changing economic conditions. Large companies may not reach the same levels of growth or performance as smaller companies, and they may be slower to react to competitive challenges. The performance of funds that invest in a subset of market caps could diverge from the performance of a fund that is focused on a broader representation of the stock market.&lt;/span&gt;</oef:RiskTextBlock>

For example, as a general rule, bond prices and interest rates move in opposite directions. When interest rates rise, bond prices tend to fall, and when interest rates fall, bond prices tend to go up. Bond income also is affected by changes in interest rates. Interest rates can rise or fall for a number of reasons, including, but not limited to, central bank monetary policy, inflationary or deflationary pressures, and changes in general market and economic conditions. Changing interest rates, including, but not limited to, rates that fall below zero, could have unpredictable effects on the overall market and may expose the bond markets in particular to heightened volatility and potential illiquidity. The degree to which the Fund is impacted by certain bond market risks may vary based on factors disclosed in its principal investment strategies, such as the types of bonds in which it invests and the overall credit quality, average maturity, and/or average duration of its bond holdings.&lt;/span&gt;</oef:RiskTextBlock>

In addition, negative perceptions of an issuer&#x2019;s ability to make payments can cause the price of a security to decline. While all debt securities are subject to credit risk to some extent, those with higher credit quality ratings generally pose less credit risk than those with lower credit quality ratings.&lt;/span&gt;</oef:RiskTextBlock>

With respect to mortgage-backed, asset-backed, and similar debt securities,  prepayment typically refers to borrowers repaying their debt early (e.g.,&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:9.6pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;before the maturity date).&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:9.6pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;Prepayment of bonds held by the Fund would result in the Fund losing any price appreciation above the amount repaid (or the bond&#x2019;s call price,&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:9.6pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;in the case of callable bonds).

The Fund invests by sampling the Target Indexes, meaning that it holds a range of securities that, in the aggregate, approximates the full Target Indexes in terms of key risk factors and other characteristics. Under normal circumstances, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in the securities that make up the Target Indexes and in securities that the advisor determines have substantially identical economic characteristics to the securities that make up the Target Indexes.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:9.6pt;"&gt;With approximately 60% of its assets, the Fund seeks to track the investment performance of the Equity Target Index, which represents approximately 100% of the investable U.S. stock market and includes large-,  mid-, small-, and micro-cap stocks.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:9.6pt;"&gt;With approximately 40% of its assets, the Fund seeks to track the investment performance of the Bond Target Index, which represents a wide spectrum of public, investment-grade, taxable, bonds in the United States&#x2014;including government, corporate, and international dollar-denominated bonds, as well as mortgage-backed and asset-backed securities&#x2014;all with maturities of more than 1 year. The bond portion of the Fund seeks to maintain a dollar-weighted average maturity consistent with that of the Bond Target Index. As of December 31, 2025, the dollar-weighted average maturity of the Bond Target Index was 8.1 years.&lt;/span&gt;</oef:StrategyNarrativeTextBlock>

Companies can be further classified into micro- or mega-cap. Different factors can affect each market cap uniquely, and historically small- and mid-cap stocks have typically been more volatile due to the effects of changing economic conditions. Large companies may not reach the same levels of growth or performance as smaller companies, and they may be slower to react to competitive challenges. The performance of funds that invest in a subset of market caps could diverge from the performance of a fund that is focused on a broader representation of the stock market.&lt;/span&gt;</oef:RiskTextBlock>

For example, as a general rule, bond prices and interest rates move in opposite directions. When interest rates rise, bond prices tend to fall, and when interest rates fall, bond prices tend to go up. Bond income also is affected by changes in interest rates. Interest rates can rise or fall for a number of reasons, including, but not limited to, central bank monetary policy, inflationary or deflationary pressures, and changes in general market and economic conditions. Changing interest rates, including, but not limited to, rates that fall below zero, could have unpredictable effects on the overall market and may expose the bond markets in particular to heightened volatility and potential illiquidity. The degree to which the Fund is impacted by certain bond market risks may vary based on factors disclosed in its principal investment strategies, such as the types of bonds in which it invests and the overall credit quality, average maturity, and/or average duration of its bond holdings.&lt;/span&gt;</oef:RiskTextBlock>

The Fund invests in common and preferred stocks, both directly and indirectly (such as through depositary receipts), and is not constrained with respect to market capitalization or industry allocation. Under normal circumstances, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in stocks of companies that Baillie Gifford Overseas Limited (&#x201c;Baillie Gifford&#x201d;), the Fund&#x2019;s advisor, determines contribute towards a more sustainable and inclusive world.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:9.7pt;"&gt;The Fund&#x2019;s portfolio managers employ a bottom-up approach to stock selection and select companies without being constrained by any benchmark or securities index. The portfolio managers focus on company research and the long-term outlook of companies and industries, assessing  a range of factors, including: long-term growth potential, geographic and industry positioning, competitive advantage (or attributes that give a company a favorable business position relative to its competitors), management, financial strength and valuation. In parallel, the portfolio managers assess potential holdings&#x2019; contributions to sustainability and inclusiveness, focusing on the ability of companies to deliver positive change in areas including: (1) Social Inclusion and Education, focusing on a more inclusive society and access to and quality of education; (2) Healthcare and Quality of Life, focusing on improving healthcare that affects quality of life; (3) Environment and Resource Needs, focusing on environmental impacts that affect basic resources; and (4) Base of the Pyramid, focusing on addressing the needs of the poorest populations. The portfolio managers assess positive change across these four categories by considering the company&#x2019;s intent, how its products and services contribute to solving a global challenge, and the company&#x2019;s business practices. To measure and report on impact, the portfolio managers monitor the progress of each issuer using metrics and/or milestones specific to each company and selected by Baillie Gifford. The portfolio managers pursue an active, positive approach; investment decisions are generally not made on the basis of negative &#x201c;screening&#x201d; of companies viewed as socially irresponsible.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:9.7pt;"&gt;The intended outcome is a portfolio of between 25 and 50 growth companies with the potential to outperform the Fund&#x2019;s performance benchmark over the long term and which the portfolio managers consider to have core ambitions of delivering a positive change. The process can result in significant exposure to a single country or a small number of countries.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:9.7pt;"&gt;The Fund is considered nondiversified, as defined under the Investment Company Act of 1940, which means that it may invest a greater percentage of &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;its assets in the securities of particular issuers, industries, or sectors as compared with diversified funds. The Fund aims to hold securities for long periods (typically 5-10 years), which results in relatively low portfolio turnover and is in line with the Fund&#x2019;s long-term investment outlook.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:9.7pt;"&gt;The Fund may invest without limitation in securities quoted or denominated in currencies other than the U.S. dollar and may hold such currencies. 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.&lt;/span&gt;</oef:StrategyNarrativeTextBlock>

The advisor selects securities for the Fund based on the ESG criteria described in the Fund&#x2019;s principal investment strategies. As a result,&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:9.7pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;the Fund&#x2019;s investments could, in the aggregate, trail the returns of other funds that use ESG criteria or underperform the market as a whole. The advisor&#x2019;s use of ESG criteria may result in the Fund becoming focused, at times, in a particular market sector, which would subject the Fund to proportionately higher exposure to the risks of that sector. Interpretations of what it means for a company or issuer to exhibit ESG characteristics can&#x2014;and do&#x2014;vary significantly across individuals, advisors, and other funds that use ESG criteria. The advisor&#x2019;s assessment of whether or not a company or issuer meets the ESG criteria described in the Fund&#x2019;s principal investment strategies, or the ESG criteria  itself, may not align with your personal view of what it means for a company or issuer to exhibit ESG characteristics generally. Further, individual securities held by the Fund may not reflect your personal preferences, beliefs, expectations, and/or values. In order to assess a company or issuer against the ESG criteria described in the Fund&#x2019;s principal investment strategies, the advisor depends on the availability of data obtained through voluntary or third-party reporting. There can be no assurance that this data will be accurate, complete, or current, which could result in an inaccurate assessment of a company or issuer.&lt;/span&gt;</oef:RiskTextBlock>

In addition, investor sentiment and expectations regarding these factors can also impact the markets. Different parts of the market, including different industries and sectors as well as different types of securities, may react differently to factors that affect the market.

World events could adversely affect the value and/or liquidity of securities of foreign companies or foreign issuers, potentially in ways that differ from impacts to U.S. companies or issuers. Further, global economies and financial markets are becoming increasingly interconnected, which increases the possibility that conditions in one country or region could adversely impact a different country or region. In addition, the rights and remedies associated with investments in a fund that invests in foreign securities may be different than a fund that invests in domestic securities. To the extent that the Fund invests a large portion of its assets in securities of issuers located primarily in one country or region, the Fund&#x2019;s performance may be hurt disproportionately by the poor performance of its investments in such country or region.&#x202f;&lt;/span&gt;</oef:RiskTextBlock>

Compared with developed markets, emerging markets can have greater custodial and operational risks; less developed legal, tax, regulatory, financial reporting, accounting, and recordkeeping systems; and greater political, social, and economic instability than developed markets. In addition, emerging markets generally have less efficient trading markets with lower overall liquidity and more volatile currency exchange rates. The Fund also may invest in frontier markets which have even smaller economies and less developed capital markets and which carry even greater risks, including potential liquidity issues and challenges clearing and settling trades. There is also the possibility for disruptions, corrections, and failed settlements, which can result in trading losses. Each of these risks can cause losses to the Fund&#x2019;s investments and/or impact the Fund&#x2019;s performance.&lt;/span&gt;</oef:RiskTextBlock>

The performance of funds that invest in a subset of market caps could diverge from the performance of a fund that is focused on a broader representation of the stock market.&lt;/span&gt;</oef:RiskTextBlock>

Growth stocks typically produce lower yields because growth companies prefer to reinvest earnings into research and development to promote growth and increase profitability. Research and development can be expensive and may not always produce favorable results, which could harm a company&#x2019;s performance relative to the broader market.&lt;/span&gt;</oef:RiskTextBlock>
