As a result, a non-diversified fund will likely invest a greater percentage of its assets in fewer issuers, and the performance of those issuers may have a greater effect on the Fund&#x2019;s performance compared to a diversified fund. Thus, a non-diversified fund is more likely to experience significant fluctuations in value, exposing the Fund to a greater risk of loss in any given period than a diversified fund.&lt;/div&gt; </oef:RiskTextBlock>

The performance of those issuers may have a greater effect on the Fund&#x2019;s performance compared to a fund that has a greater diversity of investments in multiple issuers. Thus, a fund with concentrated investments in certain single issuers is more likely to experience significant fluctuations in value, exposing the Fund to a greater risk of loss in any given period. The Fund currently has significant investments in Space Exploration Technologies Corp. (&#x201c;SpaceX&#x201d;) and Tesla,&#160;Inc. (&#x201c;Tesla&#x201d;). As a result, the net asset value of the Fund will be materially impacted by the price of each issuer&#x2019;s stock. Before investing in the Fund, investors should carefully consider publicly available information about SpaceX and Tesla. As long as the Fund maintains a substantial investment in these issuers, the Fund&#x2019;s performance will be significantly affected by the performance of the stock and a decline in the price of Tesla or SpaceX stock could materially and adversely affect&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: calibri;"&gt;your investment in the Fund. This risk may be amplified because these companies share the same Chief Executive Officer and major stockholder. See &#x201c;Common CEO Risk.&#x201d;&lt;/div&gt; </oef:RiskTextBlock>

As a result, the Fund may be exposed to risks associated with an individual which may be greater than would be the case if measured only by investments on a per company basis. Notably, the Fund has made investments in SpaceX and Tesla, the Chief Executive Officer of each is Elon Musk.

As a result, the Fund will be particularly exposed to the risks of that company or industry relative to the risk exposure of investment companies holding a diversified portfolio of securities or those that seek to maintain near-index weightings in their portfolio securities. Accordingly, in those cases, the Fund will be disproportionately exposed to the market conditions, interest rates, and economic, regulatory, or financial developments that significantly affect that company or industry. For example, due to the size of the Fund&#x2019;s investments in SpaceX and Tesla, which represent about 33% and 22%, respectively, of its net assets as of the date of this prospectus, the Fund will be adversely impacted by developments affecting the aerospace &amp;amp; defense, automotive and energy industries, as well as governmental environmental regulations.

Use of leverage also tends to magnify the volatility of the Fund&#x2019;s returns.

Growth stocks tend to be more expensive relative to their earnings or assets compared to other types of stocks.

In addition, turbulence as has recently been experienced, caused, among other reasons, by increased inflation, tightening monetary policy and interest rate increases by the US Federal Reserve or similar international bodies, and changes in U.S. trade policy. Reduced liquidity in financial markets may continue to negatively affect many issuers, which could have an adverse effect on your Fund investment. Events involving limited liquidity, defaults, non-performance or other adverse developments that affect one industry, such as the financial services industry, or concerns or rumors about any events of these kinds, have in the past and may in the future lead to market-wide liquidity problems, may spread to other industries, and could negatively affect the value and liquidity of the Fund&#x2019;s investments. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market, such as Russia&#x2019;s invasion of Ukraine in February 2022 and the world-wide response to it, have and may continue to adversely impact issuers and markets worldwide. Increasingly strained relations between countries, including between the U.S. and traditional allies and/or adversaries, could adversely affect U.S. issuers as well as non-U.S. issuers that rely on the United States for trade. A fund&#x2019;s securities may be negatively impacted by inflation (or expectations for inflation), interest rates, global demand for particular products/services or resources, supply chain disruptions, natural disasters, pandemics, epidemics, terrorism, war, military confrontations, changes in trade regulations, elevated levels of government debt, internal unrest and discord, economic sanctions, regulatory events and governmental or quasi-governmental actions, among others. Ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, including the joint U.S.-Israeli strikes on Iran in February 2026, present considerable market risks, the ultimate effects of which are not known but could profoundly affect global economies and markets. Raising the ceiling on U.S. government debt has become increasingly politicized. Any failure to increase the total amount that the U.S. government is authorized to borrow could lead to a default on U.S. government obligations, with unpredictable consequences for economies and markets in the U.S. and elsewhere.&lt;/div&gt; </oef:RiskTextBlock>

Securities of small- and mid-sized companies may not be well known to most investors, and the securities may be less actively traded than those of large businesses. The securities of small- and mid-sized companies may fluctuate in price more widely than the stock market generally, and they may be more difficult to sell during market downturns. Small- and mid-sized companies rely more on the skills of management and on their continued tenure. Investing in small- and mid-sized companies requires a long-term outlook and may require shareholders to assume more risk and to have more patience than investing in the securities of larger, more established companies.&lt;/div&gt; </oef:RiskTextBlock>

The Fund&#x2019;s investment goals, policies, guidelines and restrictions are, in all material respects, equivalent to the predecessor partnership&#x2019;s. The following information shows the Fund&#x2019;s annual returns and long-term performance reflecting the actual fees and expenses that were charged when the Fund was a partnership and since it converted to a mutual fund. The predecessor partnership charged a 20% performance fee after it reached a certain performance benchmark. If the annual returns for the Fund did not reflect the performance fee for the years the partnership charged a performance fee, the returns would have been higher. The Fund does not charge a performance fee. From its inception on January&#160;31, 1992 through April&#160;30, 2003, the predecessor partnership was not subject to certain investment restrictions, diversification requirements and other restrictions of the Investment Company Act of 1940, as amended (the &#x201c;1940 Act&#x201d;), or the Internal Revenue Code of 1986, as amended (the&#160;&#x201c;Code&#x201d;), which if they had been applicable, might have adversely affected its performance.

The table also shows the average annual returns of the Fund&#x2019;s Institutional Shares and R6&#160;Shares, but it does not show after-tax returns.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: calibri;"&gt;After-tax returns are calculated using the highest individual federal marginal income tax rate in effect at the time of each distribution and assumed sale, but they do not include the impact of state and local taxes. Because the predecessor partnership did not have a distribution policy prior to May&#160;1, 2003, the Fund is unable to show after-tax returns prior to that date.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 10pt; font-family: calibri;"&gt;Your actual after-tax returns depend on your own tax situation and may differ from those shown. After-tax returns reflect past tax effects and are not predictive of future&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: calibri;"&gt;tax effects. After-tax returns are not relevant to investors who hold their Fund shares in a tax-deferred account (including a&lt;br/&gt;401(k) or IRA or Coverdell account), or to investors that are tax-exempt.&lt;/div&gt; </oef:PerformanceTableNarrativeTextBlock>

The Adviser defines small- and mid-sized companies as those, at the time of purchase, with market capitalizations up to the largest market cap stock in the Russell Midcap Growth Index at reconstitution. The Adviser seeks to invest in businesses it believes have significant opportunities for growth, sustainable competitive advantages, exceptional management, and an attractive valuation.

As a result, a non&#x2011;diversified fund will likely invest a greater percentage of its assets in fewer issuers, and the performance of those issuers may have a greater effect on the Fund&#x2019;s performance compared to a diversified fund. Thus, a non&#x2011;diversified fund is more likely to experience significant fluctuations in value, exposing the Fund to a greater risk of loss in any given period than a diversified fund. &lt;/div&gt;</oef:RiskTextBlock>

The performance of those issuers may have a greater effect on the Fund&#x2019;s performance compared to a fund that has a greater diversity of investments in multiple issuers. Thus, a fund with concentrated investments in certain single issuers is more likely to experience significant fluctuations in value, exposing the Fund to a greater risk of loss in any given period. The Fund currently has significant investments in Space Exploration Technologies Corp. (&#x201c;SpaceX&#x201d;) and Tesla, Inc. (&#x201c;Tesla&#x201d;). As a result, the net asset value of the Fund will be materially impacted by the price of each issuer&#x2019;s stock. Before investing in the Fund, investors should carefully consider publicly available information about SpaceX and Tesla. As long as the Fund maintains a substantial investment in these issuers, the Fund&#x2019;s performance &lt;/div&gt;&lt;div style="margin-top:0pt;margin-bottom:0pt;font-size:10pt;font-family:calibri;"&gt; will be significantly affected by the performance of the stock and a decline in the price of SpaceX or Tesla stock could materially and adversely affect your investment in the Fund. This risk may be amplified because these companies share the same Chief Executive Officer and major stockholder. See &#x201c;Common CEO Risk.&#x201d; &lt;/div&gt;</oef:RiskTextBlock>

As a result, the Fund may be exposed to risks associated with an individual which may be greater than would be the case if measured only by investments on a per company basis.

As a result, the Fund will be particularly exposed to the risks of that company or industry relative to the risk exposure of investment companies holding a diversified portfolio of securities or those that seek to maintain near-index weightings in their portfolio securities. Accordingly, in those cases, the Fund will be disproportionately exposed to the market conditions, interest rates, and economic, regulatory, or financial developments that significantly affect that company or industry. For example, due to the size of the Fund&#x2019;s investments in SpaceX and Tesla, which represent about 19% and 6%, respectively, of its net assets as of the date of this prospectus, the Fund will be adversely impacted by developments affecting the aerospace &amp;amp; defense, automotive and energy industries, as well as governmental environmental regulations.

As a result, because growth stocks tend to be sensitive to changes in their earnings and to increasing interest rates and inflation, they tend to be more volatile than other types of stocks.

In addition, turbulence as has recently been experienced, caused, among other reasons, by increased inflation, tightening monetary policy and interest rate increases by the US Federal Reserve or similar international bodies, and changes in U.S. trade policy. Reduced liquidity in financial markets may continue to negatively affect many issuers, which could have an adverse effect on your Fund investment. Events involving limited liquidity, defaults, non-performance or other adverse developments that affect one industry, such as the financial services industry, or concerns or rumors about any events of these kinds, have in the past and may in the future lead to market-wide liquidity problems, may spread to other industries, and could negatively affect the value and liquidity of the Fund&#x2019;s investments. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market, such as Russia&#x2019;s invasion of Ukraine in February 2022 and the world-wide response to it, have and may continue to adversely impact issuers and markets worldwide. Increasingly strained relations between countries, including between the U.S. and traditional allies and/or adversaries, could adversely affect U.S. issuers as well as non-U.S. issuers that rely on the United States for trade. A fund&#x2019;s securities may be negatively impacted by inflation (or expectations for inflation), interest rates, global demand for particular products/services or resources, supply chain disruptions, natural disasters, pandemics, epidemics, terrorism, war, military confrontations, changes in trade regulations, elevated levels of government debt, internal unrest and discord, economic sanctions, regulatory events and governmental or quasi-governmental actions, among others. Ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, including the joint U.S.-Israeli strikes on Iran in February 2026, present considerable market risks, the ultimate effects of which are not known but could profoundly affect global economies and markets. Raising the ceiling on U.S. government debt has become increasingly politicized. Any failure to increase the total amount that the U.S. government is authorized to borrow could lead to a default on U.S. government obligations, with unpredictable consequences for economies and markets in the U.S. and elsewhere. &lt;/div&gt;</oef:RiskTextBlock>

Securities of small-and mid-sized companies may not be well known to most investors, and the securities may be less actively traded than those of large businesses. The securities of small-and mid-sized companies may fluctuate in price more widely than the stock market generally, and they may be more difficult to sell during market downturns. Small-and mid-sized companies rely more on the skills of management and on their continued tenure. Investing in small-and mid-sized companies requires a long-term outlook and may require shareholders to assume more risk and to have more patience than investing in the securities of larger, more established companies. &lt;/div&gt;</oef:RiskTextBlock>

The Fund was added as a series of Baron Select Funds, a Delaware statutory trust, on June&#160;30, 2008. The Fund&#x2019;s investment goals, policies, guidelines and restrictions are, in all material respects, equivalent to the predecessor partnership&#x2019;s. The following information shows the Fund&#x2019;s annual returns and long-term performance reflecting the actual fees and expenses that were charged when the Fund was a partnership and since it converted to a mutual fund. The predecessor partnership charged a 15% performance fee after it reached a certain performance benchmark. If the annual returns for the Fund did not reflect the performance fee for the years the partnership charged a performance fee, the returns would have been higher. The Fund does not charge a performance fee. From its inception on May&#160;31, 1996 through June&#160;30, 2008, the predecessor partnership was not subject to certain investment restrictions, diversification requirements and other restrictions of the Investment Company Act of 1940, as amended (the &#x201c;1940 Act&#x201d;), or the Internal Revenue Code of 1986, as amended (the &#x201c;Code&#x201d;), which if they had been applicable, might have adversely affected its performance.

This table shows how the Fund&#x2019;s performance compares to that of the Russell 2500&#xae; Growth Index, which measures the performance of the small to mid-cap growth segment of the U.S. equity universe, in which the Fund invests, and the Russell 3000&lt;sup style="font-size:75%;vertical-align:top"&gt;&#xae;&lt;/sup&gt; Index, a broad-based securities index comprised of the 3,000 largest U.S. companies as determined by total market capitalization. The table also shows the average annual returns of the Fund&#x2019;s Institutional Shares and R6 Shares, but it does not show after-tax returns. &lt;/div&gt;&lt;div style="margin-top:6pt;margin-bottom:0pt;font-size:10pt;font-family:calibri;"&gt;After-tax returns are calculated using the highest individual federal marginal income tax rate in effect at the time of each distribution and assumed sale, but they do not include the impact of state and local taxes. Because the predecessor partnership did &lt;/div&gt;&lt;div style="margin-top:0pt;margin-bottom:0pt;font-size:10pt;font-family:calibri;"&gt; not have a distribution policy prior to July 1, 2008, the Fund is unable to show after-tax returns prior to that date. &lt;/div&gt;&lt;div style="margin-top:6pt;margin-bottom:0pt;font-size:10pt;font-family:calibri;"&gt;Your actual after-tax returns depend on your own tax situation and may differ from those shown. After-tax returns reflect past tax effects and are not predictive of future tax effects. After-tax returns are not relevant to investors who hold their Fund shares in a tax-deferred account (including a&lt;br/&gt; 401(k) or IRA or Coverdell account), or to investors that are tax-exempt. &lt;/div&gt;</oef:PerformanceTableNarrativeTextBlock>

The Fund seeks to diversify its investments among several developed countries and developing countries throughout the world, although the Fund may only invest up to 35% of its net assets in developing countries. Developing countries include countries in the MSCI Emerging Markets (EM) Index, countries in the MSCI Frontier Markets (FM) Index and other countries determined by the Adviser to be developing countries based on classifications made by the International Monetary Fund or on country characteristics similar to those of the countries in the EM and FM Indexes.

Investments in developing countries are subject to all of the risks of non-U.S. investing generally, and have additional heightened risks due to a lack of established legal, political, business and social frameworks to support securities markets, including: delays in settling portfolio securities transactions; currency and capital controls; greater sensitivity to interest rate changes; pervasiveness of corruption and crime; currency exchange rate volatility; and inflation, deflation or currency devaluation.

Further, because exchange rate movements are volatile, the Fund&#x2019;s attempts at hedging could be unsuccessful, and it may not be possible to effectively hedge the currency risks of many developing countries. &lt;/div&gt;</oef:RiskTextBlock>

In addition, turbulence as has recently been experienced, caused, among other reasons, by increased inflation, tightening monetary policy and interest rate increases by the US Federal Reserve or similar international bodies, and changes in U.S. trade policy. Reduced liquidity in financial markets may continue to negatively affect many issuers, which could have an adverse effect on your Fund investment. Events involving limited liquidity, defaults, non-performance or other adverse developments that affect one industry, such as the financial services industry, or concerns or rumors about any events of these kinds, have in the past and may in the future lead to market-wide liquidity problems, may spread to other industries, and could negatively affect the value and liquidity of the Fund&#x2019;s investments. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market, such as Russia&#x2019;s invasion of Ukraine in February 2022 and the world-wide response to it, have and may continue to adversely impact issuers and markets worldwide. Increasingly strained relations between countries, including between the U.S. and traditional allies and/or adversaries, could adversely affect U.S. issuers as well as non-U.S. issuers that rely on the United States for trade. A fund&#x2019;s securities may be negatively impacted by inflation (or expectations for inflation), interest rates, global demand for particular products/services or resources, supply chain disruptions, natural disasters, pandemics, epidemics, terrorism, war, military confrontations, changes in trade regulations, elevated levels of government debt, internal unrest and discord, economic sanctions, regulatory events and governmental or quasi-governmental actions, among others. Ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, including the joint U.S.-Israeli strikes on Iran in February 2026, present considerable market risks, the ultimate effects of which are not known but could profoundly affect global economies and markets. Raising the ceiling on U.S. government debt has become increasingly politicized. Any failure to increase the total amount that the U.S. government is authorized to borrow could lead to a default on U.S. government obligations, with unpredictable consequences for economies and markets in the U.S. and elsewhere. &lt;/div&gt;</oef:RiskTextBlock>

Changes in these policies could adversely impact affected industries or companies in China. China&#x2019;s economy, particularly its export-oriented industries, may be adversely impacted by trade or political disputes with China&#x2019;s major trading partners, including the U.S. The United States has imposed tariffs and other trade barriers on Chinese exports, has restricted sales of certain categories of goods to China, and has established barriers to investments in China. &lt;/div&gt;&lt;div style="margin-top:0pt;margin-bottom:0pt;font-size:10pt;font-family:calibri;"&gt; Trade disputes may adversely affect the economies of the United States and its trading partners, as well as companies directly or indirectly affected and financial markets generally. The United States government has prohibited U.S. persons from investing in Chinese companies designated as related to the Chinese military. These and possible future restrictions could limit the Fund&#x2019;s opportunities for investment and require the sale of securities at a loss or make them illiquid. Moreover, the Chinese government is involved in a longstanding dispute with Taiwan that has included threats of invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt unification of Taiwan by force, or if other geopolitical conflicts develop or get worse, economies, markets and individual securities may be severely affected both regionally and globally, and the value of the Fund&#x2019;s assets may go down. In addition, as its consumer class continues to grow, China&#x2019;s domestically oriented industries may be especially sensitive to changes in government policy and investment cycles. If China were to exert its authority so as to alter the economic, political or legal structures or the existing social policy of Hong Kong, investor and business confidence in Hong Kong could be negatively affected and have an adverse effect on the Fund&#x2019;s investments. &lt;/div&gt;</oef:RiskTextBlock>

Securities of small- and mid-sized companies may not be well known to most investors, and the securities may be less actively traded than those of large businesses. The securities of small- and mid-sized companies may fluctuate in price more widely than the stock market generally, and they may be more difficult to sell during market downturns. Small- and mid-sized companies rely more on the skills of management and on their continued tenure. Investing in small- and mid-sized companies requires a long-term outlook and may require shareholders to assume more risk and to have more patience than investing in the securities of larger, more established companies. &lt;/div&gt;</oef:RiskTextBlock>

The Industrials Sector includes manufacturers and distributors of capital goods such as aerospace and defense, building projects, electrical equipment and machinery and companies that offer construction and engineering services. It also includes providers of commercial and professional services including printing, environmental and facilities services, office services and supplies, security and alarm services, human resource and employment services, research and consulting services. It also includes companies that provide transportation services. The Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the Industrials Sector. The prices of the securities of companies operating in the Industrials Sector may fluctuate due to the level and volatility of commodity prices, the exchange value of the dollar, import controls, worldwide competition, liability for environmental damage, depletion of resources, and mandated expenditures for safety and pollution control devices. &lt;/div&gt;</oef:RiskTextBlock>

The Fund&#x2019;s concentration in these companies may present more risks than if it were broadly diversified over numerous industries and sectors of the economy. A downturn in these companies would have a larger impact on the Fund than on a mutual fund that does not concentrate in such companies.

Growth stocks tend to be more expensive relative to their earnings or assets compared to other types of stocks. As a result, because growth stocks tend to be sensitive to changes in their earnings and to increasing interest rates and inflation, they tend to be more volatile than other types of stocks. In response, from time to time, growth investing as an investment style may go out of favor with investors. &lt;/div&gt;</oef:RiskTextBlock>

In addition, turbulence as has recently been experienced, caused, among other reasons, by increased inflation, tightening monetary policy and interest rate increases by the US Federal Reserve or similar international bodies, and changes in U.S. trade policy. Reduced liquidity in financial markets may continue to negatively affect many issuers, which could have an adverse effect on your Fund investment. Events involving limited liquidity, defaults, non-performance or other adverse developments that affect one industry, such as the financial services industry, or concerns or rumors about any events of these kinds, have in the past and may in the future lead to market-wide liquidity problems, may spread to other industries, and could negatively affect the value and liquidity of the Fund&#x2019;s investments. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market, such as Russia&#x2019;s invasion of Ukraine in February 2022 and the world-wide response to it, have and may continue to adversely impact issuers and markets worldwide. Increasingly strained relations between countries, including between the U.S. and traditional allies and/or adversaries, could adversely affect U.S. issuers as well as non-U.S. issuers that rely on the United States for trade. A fund&#x2019;s securities may be negatively impacted by inflation (or expectations for inflation), interest rates, global demand for particular products/services or resources, supply chain disruptions, natural disasters, pandemics, epidemics, terrorism, war, military confrontations, changes in trade regulations, elevated levels of government debt, internal unrest and discord, economic sanctions, regulatory events and governmental or quasi-governmental actions, among others. Ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, including the joint U.S.-Israeli strikes on Iran in February 2026, present considerable market risks, the ultimate effects of which are not known but could profoundly affect global economies and markets. Raising the ceiling on U.S. government debt has become increasingly politicized. Any failure to increase the total amount that the U.S. government is authorized to borrow could lead to a default on U.S. government obligations, with unpredictable consequences for economies and markets in the U.S. and elsewhere. &lt;/div&gt;</oef:RiskTextBlock>

The securities of small-and mid-sized companies may fluctuate in price more widely than the stock market generally, and they may be more difficult to sell during market downturns. Small-and mid-sized companies rely more on the skills of management and on their continued tenure. Investing in small-and mid-sized companies requires a long-term outlook and may require shareholders to assume more risk and to have more patience than investing in the securities of larger, more established companies. &lt;/div&gt;</oef:RiskTextBlock>

The Fund may invest up to 20% of its net assets in developed countries and in frontier countries as defined by the MSCI Frontier Markets (FM) Index. The Fund&#x2019;s investments will be in at least three different countries. The Fund may purchase securities of companies of any market capitalization.

Government actions, bureaucratic obstacles and inconsistent economic reform within the Indian government have had a significant effect on the Indian economy and could adversely affect market conditions, economic growth and the profitability of private enterprises in India. Global factors and foreign actions may inhibit the flow of foreign capital on which India is dependent to sustain its growth. Large portions of many Indian companies remain in the hands of their founders (including members of their families). Corporate governance standards of family-controlled companies may be weaker and less transparent, which increases the potential for loss and unequal treatment of investors. Religious, cultural and military disputes persist in India and between India and Pakistan (as well as sectarian groups within each country). &lt;/div&gt;</oef:RiskTextBlock>

Changes in these policies could adversely impact affected industries or companies in China. China&#x2019;s economy, particularly its export-oriented industries, may be adversely impacted by trade or political disputes with China&#x2019;s major trading partners, including the U.S. The United States has imposed tariffs and other trade barriers on Chinese exports, has restricted sales of certain categories of goods to China, and has established barriers to investments in China. Trade disputes may adversely affect the economies of the United States and its trading partners, as well as companies directly or indirectly affected and financial markets generally. The United States government has prohibited U.S. persons from investing in Chinese companies designated as related to the Chinese military. These and possible future restrictions could limit the Fund&#x2019;s opportunities for investment and require the sale of securities at a loss or make them illiquid. Moreover, the Chinese government is involved in a longstanding dispute with Taiwan that has included threats of invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt unification of Taiwan by force, or if other geopolitical conflicts develop or get worse, economies, markets and individual securities may be severely affected both regionally and globally, and the value of the Fund&#x2019;s assets may go down. In addition, as its consumer class continues to grow, China&#x2019;s domestically oriented industries may be especially sensitive to changes in government policy and investment cycles. If China were to exert its authority so as to alter the economic, political or legal structures or the existing social policy of Hong Kong, investor and business confidence in Hong Kong could be negatively affected and have an adverse effect on the Fund&#x2019;s investments. &lt;/div&gt;</oef:RiskTextBlock>

Instead of directly owning the equity securities of a Chinese company, a VIE enters into service and other contracts with the Chinese company. Although the VIE has no equity ownership of the Chinese company, the contractual arrangements permit the VIE to consolidate the Chinese company into its financial statements. VIE investments are subject to the risk that any breach of these contractual arrangements will be subject to Chinese law and jurisdiction, that Chinese law may be interpreted or change in a way that affects the enforceability of the VIE&#x2019;s arrangements, or that contracts between the Chinese company and the VIE may otherwise not be enforceable under Chinese law. &lt;/div&gt;</oef:RiskTextBlock>

In addition, turbulence as has recently been experienced, caused, among other reasons, by increased inflation, tightening monetary policy and interest rate increases by the US Federal Reserve or similar international bodies, and changes in U.S. trade policy. Reduced liquidity in financial markets may continue to negatively affect many issuers, which could have an adverse effect on your Fund investment. Events involving limited liquidity, defaults, non-performance or other adverse developments that affect one industry, such as the financial services industry, or concerns or rumors about any events of these kinds, have in the past and may in the future lead to market-wide liquidity problems, may spread to other industries, and could negatively affect the value and liquidity of the Fund&#x2019;s investments. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market, such as Russia&#x2019;s invasion of Ukraine in February 2022 and the world-wide response to it, have and may continue to adversely impact issuers and markets worldwide. Increasingly strained relations between countries, including between the U.S. and traditional allies and/or adversaries, could adversely affect U.S. issuers as well as non-U.S. issuers that rely on the United States for trade. A fund&#x2019;s securities may be negatively impacted by inflation (or expectations for inflation), interest rates, global demand for particular products/services or resources, supply chain disruptions, natural disasters, pandemics, epidemics, terrorism, war, military confrontations, changes in trade regulations, elevated levels of government debt, internal unrest and discord, economic sanctions, regulatory events and governmental or quasi-governmental actions, among others. Ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, including the joint U.S.-Israeli strikes on Iran in February 2026, present considerable market risks, the ultimate effects of which are not known but could profoundly affect global economies and markets. Raising the ceiling on U.S. &lt;/div&gt;&lt;div style="margin-top:0pt;margin-bottom:0pt;font-size:10pt;font-family:calibri;"&gt; government debt has become increasingly politicized.

Securities of small- and mid-sized companies may not be well known to most investors, and the securities may be less actively traded than those of large businesses. The securities of small- and mid-sized companies may fluctuate in price more widely than the stock market generally, and they may be more difficult to sell during market downturns. Small- and mid-sized companies rely more on the skills of management and on their continued tenure. Investing in small- and mid-sized &lt;/div&gt;&lt;div style="margin-top:0pt;margin-bottom:0pt;font-size:10pt;font-family:calibri;"&gt; companies requires a long-term outlook and may require shareholders to assume more risk and to have more patience than investing in the securities of larger, more established companies. &lt;/div&gt;</oef:RiskTextBlock>

The performance of those issuers may have a greater effect on the Fund&#x2019;s performance compared to a fund that has a greater diversity of investments in multiple issuers. Thus, a fund with concentrated investments in certain single issuers is more likely to experience significant fluctuations in value, exposing the Fund to a greater risk of loss in any given period. The Fund currently has a significant investment in Space Exploration Technologies Corp. (&#x201c;SpaceX&#x201d;). As a result, the net asset value of the Fund will be materially impacted by the price of the issuer&#x2019;s stock. Before investing in the Fund, investors should carefully consider publicly available information about SpaceX. As long as the Fund maintains a substantial investment in this issuer, the Fund&#x2019;s performance will be significantly affected by the performance of the stock and a decline in the price of SpaceX stock could materially and adversely affect your investment in the Fund.&lt;/div&gt; </oef:RiskTextBlock>

As a result, the Fund will be particularly exposed to the risks of that company or industry relative to the risk exposure of investment companies holding a diversified portfolio of securities or those that seek to maintain near-index weightings in their portfolio securities. Accordingly, in those cases, the Fund will be disproportionately exposed to the market conditions, interest rates, and economic, regulatory, or financial developments that significantly affect that company or industry. For example, due to the size of the Fund&#x2019;s investment in SpaceX, which represents about 18% of its net assets as of the date of this prospectus, the Fund will be adversely impacted by developments affecting the aerospace &amp;amp; defense industries, as well as governmental environmental regulations.

Growth stocks tend to be more expensive relative to their earnings or assets compared to other types of stocks. As a result, because growth stocks tend to be sensitive to changes in their earnings and to increasing interest rates and inflation, they tend to be more volatile than other types of stocks. In response, from time to time, growth investing as an investment style may go out of favor with investors.&lt;/div&gt; </oef:RiskTextBlock>

In addition, turbulence as has recently been experienced, caused, among other reasons, by increased inflation, tightening monetary policy and interest rate increases by the US Federal Reserve or similar international bodies, and changes in U.S. trade policy. Reduced liquidity in financial markets may continue to negatively affect many issuers, which could have an adverse effect on your Fund investment. Events involving limited liquidity, defaults, non-performance or other adverse developments that affect one industry, such as the financial services industry, or concerns or rumors about any events of these kinds, have in the past and may in the future lead to market-wide liquidity problems, may spread to other industries, and could negatively affect the value and liquidity of the Fund&#x2019;s investments. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market, such as Russia&#x2019;s invasion of Ukraine in February 2022 and the world-wide response to it, have and may continue to adversely impact issuers and markets worldwide. Increasingly strained relations between countries, including between the U.S. and traditional allies and/or adversaries, could adversely affect U.S. issuers as well as non-U.S. issuers that rely on the United States for trade. A fund&#x2019;s securities may be negatively impacted by inflation (or expectations for inflation), interest rates, global demand for particular products/services or resources, supply chain disruptions, natural disasters, pandemics, epidemics, terrorism, war, military confrontations, changes in&lt;/div&gt;  &lt;div style="margin-top: 0pt; margin-bottom: 0pt; font-size: 10pt; font-family: calibri;"&gt;trade regulations, elevated levels of government debt, internal unrest and discord, economic sanctions, regulatory events and governmental or quasi-governmental actions, among others. Ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, including the joint U.S.-Israeli strikes on Iran in February 2026, present considerable market risks, the ultimate effects of which are not known but could profoundly affect global economies and markets. Raising the ceiling on U.S. government debt has become increasingly politicized. Any failure to increase the total amount that the U.S.&#160;government is authorized to borrow could lead to a default on U.S. government obligations, with unpredictable consequences for economies and markets in the U.S.&#160;and elsewhere.&lt;/div&gt; </oef:RiskTextBlock>

Securities of small-and mid-sized companies may not be well known to most investors, and the securities may be less actively traded than those of large businesses. The securities of small-and mid-sized companies may fluctuate in price more widely than the stock market generally, and they may be more difficult to sell during market downturns. Small-and mid-sized companies rely more on the skills of management and on their continued tenure. Investing in small-and mid-sized companies requires a long-term outlook and may require shareholders to assume more risk and to have more patience than investing in the securities of larger, more established companies.&lt;/div&gt; </oef:RiskTextBlock>

Various factors may also adversely affect a borrower&#x2019;s or a lessee&#x2019;s ability to meet its obligations to the REIT.

Conversely, when interest rates rise or perceived credit quality weakens, the market value of the affected debt securities generally declines. In addition, changes in monetary policy may exacerbate the risks associated with changing interest rates.

Growth stocks tend to be more expensive relative to their earnings or assets compared to other types of stocks. As a result, because growth stocks tend to be sensitive to changes in their earnings and to increasing interest rates and inflation, they tend to be more volatile than other types of stocks.

These declines may be the result of, among other things, political, regulatory, market, economic or social developments affecting the relevant market(s). In addition, turbulence as has recently been experienced, caused, among other reasons, by increased inflation, tightening monetary policy and interest rate increases by the US Federal Reserve or similar international bodies, and changes in U.S. trade policy. Reduced liquidity in financial markets may continue to negatively affect many issuers, which could have an adverse effect on your Fund investment. Events involving limited liquidity, defaults, non-performance or other adverse developments that affect one industry, such as the financial services industry, or concerns or rumors about any events of these kinds, have in the past and may in the future lead to market-wide liquidity problems, may spread to other industries, and could negatively affect the value and liquidity of the Fund&#x2019;s investments. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market, such as Russia&#x2019;s invasion of Ukraine in February 2022 and the world-wide response to it, have and may continue to adversely impact issuers and markets worldwide. Increasingly strained relations between countries, including between the U.S. and traditional allies and/or adversaries, could adversely affect U.S. issuers as well as non-U.S. issuers that rely on the United States for trade. A fund&#x2019;s securities may be negatively impacted by inflation (or expectations for inflation), interest rates, global &lt;/div&gt;&lt;div style="margin-top:0pt;margin-bottom:0pt;font-size:10pt;font-family:calibri;"&gt; demand for particular products/services or resources, supply chain disruptions, natural disasters, pandemics, epidemics, terrorism, war, military confrontations, changes in trade regulations, elevated levels of government debt, internal unrest and discord, economic sanctions, regulatory events and governmental or quasi-governmental actions, among others. Ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, including the joint U.S.-Israeli strikes on Iran in February 2026, present considerable market risks, the ultimate effects of which are not known but could profoundly affect global economies and markets. Raising the ceiling on U.S. government debt has become increasingly politicized. Any failure to increase the total amount that the U.S. government is authorized to borrow could lead to a default on U.S. government obligations, with unpredictable consequences for economies and markets in the U.S. and elsewhere. &lt;/div&gt;</oef:RiskTextBlock>

Securities of small- and mid&#x2011;sized companies may not be well known to most investors, and the securities may be less actively traded than those of large businesses. The securities of small- and mid&#x2011;sized companies may fluctuate in price more widely than the stock market generally, and they may be more difficult to sell during market downturns. Small- and mid&#x2011;sized companies rely more on the skills of management and on their continued tenure. Investing in small- and mid&#x2011;sized companies requires a long-term outlook and may require shareholders to assume more risk and to have more patience than investing in the securities of larger, more established companies. &lt;/div&gt;</oef:RiskTextBlock>

This table shows how the Fund&#x2019;s performance compares to that of the MSCI US REIT Index, which is a free float-adjusted market capitalization weighted index that is comprised of equity REITs, in which the Fund invests, and the S&amp;amp;P 500 Index, a broad-based securities index that reflects the overall U.S. equity market. The table also shows the average annual return of the Fund&#x2019;s Institutional Shares and R6 Shares, but it does not show after&#x2011;tax returns. &lt;/div&gt;&lt;div style="margin-top:6pt;margin-bottom:0pt;font-size:10pt;font-family:calibri;"&gt;After&#x2011;tax returns are calculated using the highest individual federal marginal income tax rate in effect at the time of each distribution and assumed sale, but they do not include the impact of state and local taxes. &lt;/div&gt;&lt;div style="margin-top:6pt;margin-bottom:0pt;font-size:10pt;font-family:calibri;"&gt;Your actual after&#x2011;tax returns depend on your own tax situation and may differ from those shown.

After&#x2011;tax returns are not relevant to investors who hold their Fund&#x2019;s shares in a tax&#x2011;deferred account (including a 401(k) or IRA or Coverdell account), or to investors that are tax&#x2011;exempt. &lt;/div&gt;</oef:PerformanceTableNarrativeTextBlock>

The Adviser uses various criteria to determine whether an issuer is engaged in activities related to the health care industry, including whether: (1) the issuer derives 50% or more of its revenues from activities in the health care industry; or (2) the issuer devotes 50% or more of its assets to producing sales from the health care industry.&#160;These companies may include, among others, pharmaceutical companies, biotechnology companies, life sciences tools and services companies, health care equipment companies, health care supplies companies, managed health care companies, health care services companies, health care facilities, health care distributors, and health care technology companies. The Fund strives to invest in multiple subsectors of the health care industry. The Fund&#x2019;s allocation among the different subsectors of the health care industry will vary depending upon the relative potential the Fund sees within each area. The Adviser seeks to invest in businesses it believes have significant growth opportunities, sustainable competitive advantages, exceptional management, and attractive valuations. The Fund may purchase securities of companies of any market capitalization and may invest in foreign stocks, however, investments in non-U.S. securities are limited to 35% of the Fund&#x2019;s total assets at the time of purchase. &lt;/div&gt;</oef:StrategyNarrativeTextBlock>

These actions and regulations can affect the approval process for patents, medical devices and drugs, the funding of research and medical care programs, and the operation and licensing of facilities and personnel. Biotechnology and related companies are affected by patent considerations, intense competition, rapid technology change and obsolescence, and regulatory requirements of various federal and state agencies. In addition, some of these companies are relatively small and have thinly traded securities, may not yet offer products or may offer a single product, and may have persistent losses during a new product&#x2019;s transition from development to production, or erratic revenue patterns.

Thus, a non&#x2011;diversified fund is more likely to experience significant fluctuations in value, exposing the Fund to a greater risk of loss in any given period than a diversified fund. &lt;/div&gt;</oef:RiskTextBlock>

In addition, turbulence as has recently been experienced, caused, among other reasons, by increased inflation, tightening monetary policy and interest rate increases by the US Federal Reserve or similar international bodies, and changes in U.S. trade policy. Reduced liquidity in financial markets may continue to negatively affect many issuers, which could have an adverse effect on your Fund investment. Events involving limited liquidity, defaults, non-performance or other adverse developments that affect one industry, such as the financial services industry, or concerns or rumors about any events of these kinds, have in the past and may in the future lead to market-wide liquidity problems, may spread to other industries, and could negatively affect the value and liquidity of the Fund&#x2019;s investments. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market, such as Russia&#x2019;s invasion of Ukraine in February 2022 and the world-wide response to it, have and may continue to adversely impact issuers and markets worldwide. Increasingly strained relations between countries, including between the U.S. and traditional allies and/or adversaries, could adversely affect U.S. issuers as well as non-U.S. issuers that rely on the United States for trade. A fund&#x2019;s securities may be negatively impacted by inflation (or expectations for inflation), interest rates, global demand for particular products/services or resources, supply chain disruptions, natural disasters, pandemics, epidemics, terrorism, war, military confrontations, changes in trade regulations, elevated levels of government debt, internal unrest and discord, economic sanctions, regulatory events and governmental or quasi-governmental actions, among others. Ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, including the joint U.S.-Israeli strikes on Iran in February 2026, present considerable market risks, the ultimate effects of which are not known but could profoundly affect global economies and markets. Raising the ceiling on U.S. government debt has become increasingly politicized. Any failure to increase the total amount that the U.S. government is authorized to borrow could lead to a default on U.S. government obligations, with unpredictable consequences for economies and markets in the U.S. and elsewhere. &lt;/div&gt;</oef:RiskTextBlock>

Securities of small-and mid&#x2011;sized companies may not be well known to most investors, and the securities may be less actively traded than those of large businesses. The securities of small-and mid&#x2011;sized companies may fluctuate in price &lt;/div&gt;&lt;div style="margin-top:0pt;margin-bottom:0pt;font-size:10pt;font-family:calibri;"&gt; more widely than the stock market generally, and they may be more difficult to sell during market downturns. Small-and mid&#x2011;sized companies rely more on the skills of management and on their continued tenure. Investing in small-and mid&#x2011;sized companies requires a long-term outlook and may require shareholders to assume more risk and to have more patience than investing in the securities of larger, more established companies. &lt;/div&gt;</oef:RiskTextBlock>

The Adviser considers a company or other issuer to be &#x201c;located&#x201d; in India, and a security or instrument is deemed to be an Indian security or instrument, if it has substantial ties to India. The Fund currently makes that determination based primarily on one or more of the following criteria with respect to a company or issuer, whether (i)&#160;it is organized under the laws of India; (ii)&#160;it derives at least 50% of its revenues or profits from goods produced or sold, investments made, or services performed, or has at least 50% of its assets located, within India; (iii)&#160;it has the primary trading markets for its securities in India; (iv)&#160;it has its principal place of business in or is otherwise headquartered in India; (v)&#160;it is a component of or its issuer is included in the MSCI India Index, the Fund&#x2019;s primary benchmark index or (vi)&#160;it is a governmental entity or an agency, instrumentality or a political subdivision of India. The term &#x201c;located&#x201d; and the associated criteria listed above have been defined in such a way that the Fund has latitude in determining whether an issuer should be included within India. The Fund may purchase securities of companies of any market capitalization but expects to emphasize mid and large&#x2011;sized companies. The Adviser seeks to invest in businesses it believes have significant opportunities for growth, sustainable competitive advantages, exceptional management, and an attractive valuation. &lt;/div&gt;&lt;div style="margin-top:0pt;margin-bottom:0pt;font-size:10pt;font-family:calibri;"&gt;For purposes of maintaining exposure of at least 80% of the Fund&#x2019;s assets to equity securities of issuers located in India, the Fund may also invest in American Depository Receipts (&#x201c;ADRs&#x201d;), Global Depository Receipts (&#x201c;GDRs&#x201d;) and other types of depository receipts with respect to issuers located in India. The Fund may also invest in privately placed and restricted securities. &lt;/div&gt;&lt;div style="margin-top:6pt;margin-bottom:0pt;font-size:10pt;font-family:calibri;"&gt;The Fund&#x2019;s investments are generally traded in currencies other than U.S. dollars, so the Adviser buys and sells foreign currencies to facilitate transactions in portfolio securities. The Adviser usually does not hedge against possible fluctuations in exchange rates, but exposure to a particular currency that the Adviser believes is overvalued may be hedged if the Fund has a substantial position in securities traded in that currency. The Fund may buy and sell currencies for cash at current exchange rates, or using an agreement to purchase or sell a specified currency at a specified future date or within a specified time period, at a price set at the time of the contract. &lt;/div&gt;&lt;div style="margin-top:6pt;margin-bottom:0pt;font-size:10pt;font-family:calibri;"&gt;The investment policy of the Fund relating to the types of securities in which 80% of the Fund&#x2019;s assets must be invested may be changed by the Fund&#x2019;s Board of Trustees without shareholder approval upon at least 60 days&#x2019; notice. &lt;/div&gt;</oef:StrategyNarrativeTextBlock>

Government actions, bureaucratic obstacles and inconsistent economic reform within the Indian government have had a significant effect on the Indian economy and could adversely affect market conditions, economic growth and the profitability of private enterprises in India. Global factors and foreign actions may inhibit the flow of foreign capital on which India is dependent to sustain its growth. Large portions of many Indian companies remain in the hands of their founders (including members of their families). Corporate governance standards of family-controlled companies may be weaker and less transparent, which increases the potential for loss and unequal treatment of investors. Religious, cultural and military disputes persist in India and between India and Pakistan (as well as sectarian groups within each country). &lt;/div&gt;</oef:RiskTextBlock>

The overall impact on the Fund&#x2019;s holdings can be significant, unpredictable and long-lasting, depending on the currencies represented in the portfolio and how each one appreciates or depreciates in relation to the U.S. dollar and whether currency positions are hedged. Under normal conditions, the Fund does not engage in extensive foreign currency hedging programs. Further, because exchange rate movements are volatile, the Fund&#x2019;s attempts at hedging could be unsuccessful, and it may not be possible to effectively hedge the currency risks of many developing countries. &lt;/div&gt;</oef:RiskTextBlock>

Increasingly strained relations between countries, including between the U.S. and traditional allies and/or adversaries, could adversely affect U.S. issuers as well as non-U.S. issuers that rely on the United States for trade. A fund&#x2019;s securities may be negatively impacted by inflation (or expectations for inflation), interest rates, global demand for particular products/services or resources, supply chain disruptions, natural disasters, pandemics, epidemics, terrorism, war, military confrontations, changes in trade regulations, elevated levels of government debt, internal unrest and discord, economic sanctions, regulatory events and governmental or quasi-governmental actions, among others. Ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, including the joint U.S.-Israeli strikes on Iran in February 2026, present considerable market risks, the ultimate effects of which are not known but could profoundly affect global economies and markets. Raising the ceiling on U.S. government debt has become increasingly politicized. Any failure to increase the total amount that the U.S. government is authorized to borrow could lead to a default on U.S. government obligations, with unpredictable consequences for economies and markets in the U.S. and elsewhere. &lt;/div&gt;</oef:RiskTextBlock>

Growth stocks tend to be more expensive relative to their earnings or asset compared to other types of stocks. As a result, because growth stocks tend to be sensitive to changes in their earnings and to increasing interest rates and inflation, they tend to &lt;/div&gt;&lt;div style="margin-top:0pt;margin-bottom:0pt;font-size:10pt;font-family:calibri;"&gt; be more volatile than other types of stocks.

These declines may be the result of, among other things, political, regulatory, market, economic or social developments affecting the relevant market(s). In addition, turbulence as has recently been experienced, caused, among other reasons, by increased inflation, tightening monetary policy and interest rate increases by the US Federal Reserve or similar international bodies, and changes in U.S. trade policy. Reduced liquidity in financial markets may continue to negatively affect many issuers, which could have an adverse effect on your Fund investment. Events involving limited liquidity, defaults, non&#x2011;performance or other adverse developments that affect one industry, such as the financial services industry, or concerns or rumors about any events of these kinds, have in the past and may in the future lead to market-wide liquidity problems, may spread to other industries, and could negatively affect the value and liquidity of the Fund&#x2019;s investments. &lt;/div&gt;</oef:RiskTextBlock>

Securities of small- and mid&#x2011;sized companies may not be well known to most investors, and the securities may be less actively traded than those of large businesses. The securities of small- and mid&#x2011;sized companies may fluctuate in price more widely than the stock market generally, and they may be more difficult to sell during market downturns. Small- and mid&#x2011;sized companies rely more on the skills of management and on their continued tenure. Investing in small- and mid&#x2011;sized companies requires a long term outlook and may require shareholders to assume more risk and to have more patience than investing in the securities of larger, more established companies. &lt;/div&gt;</oef:RiskTextBlock>
