Baron Asset Fund

Investment Goal

The investment goal of Baron Asset Fund (the “Fund”) is capital appreciation through long-term investments primarily in securities of mid-sized companies with undervalued assets or favorable growth prospects.

Fees and Expenses of the Fund

The table below describes the fees and expenses that you would pay if you bought and held shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below.

Annual Fund Operating Expenses

(Expenses that you pay each year as a percentage of the value of your investment)

	Management Fee		Distribution (12b-1) Fee		Other Expenses		Total Annual Fund Operating Expenses
BARON ASSET FUND
Retail Shares		1.00%		0.25%		0.04%		1.29%
Institutional Shares		1.00%		0.00%		0.03%		1.03%
R6 Shares		1.00%		0.00%		0.04%		1.04%

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

YEAR	1		3		5		10
BARON ASSET FUND
Retail Shares	$	131	$	409	$	708	$	1,556
Institutional Shares	$	105	$	328	$	569	$	1,259
R6 Shares	$	106	$	331	$	574	$	1,271

Portfolio Turnover.  The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes for Fund shareholders. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the example, affect the Fund’s performance. During the most recent fiscal year ended September 30, 2021, the Fund’s portfolio turnover rate was 9.54% of the average value of its portfolio.

Investments, Risks, and Performance

Principal Investment Strategies of the Fund

The Fund is a diversified fund that invests for the long term primarily in equity securities in the form of common stock of U.S. mid-sized growth companies. BAMCO, Inc. (“BAMCO” or the “Adviser”) defines mid-sized companies as those, at the time of purchase, with market capitalizations above $2.5 billion or the smallest market cap stock in the Russell Midcap Growth Index at reconstitution, whichever is larger, and below 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. Because of its long-term approach, the Fund could have a significant percentage of its assets invested in securities that have appreciated beyond their market capitalizations at the time of the Fund’s investment.

Principal Risks of Investing in the Fund

General Stock Market.  Fund losses may be incurred due to declines in one or more markets in which Fund investments are made. 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 caused, among other reasons, by increased inflation, or tightening monetary policy or interest rate increases by the US Federal Reserve or similar international bodies, and reduced liquidity in financial markets may negatively affect many issuers, which could have an adverse effect on your Fund investment. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers worldwide. As a result, local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions or other events could have a significant negative impact on global economic and market conditions. The coronavirus disease 2019 (COVID-19) global pandemic and the aggressive responses taken by many governments or voluntarily imposed by private parties, including closing borders, restricting travel and imposing prolonged quarantines or similar restrictions, as well as the closure of, or operational

Baron Asset Fund

changes to, many retail and other businesses, have had negative impacts, and in many cases severe negative impacts, on markets worldwide. It is not known how long such impacts, or any future impacts of other significant events described above, will or would last, but there could be a prolonged period of global economic slowdown, which may impact your Fund investment. 

Growth Investing.  Growth stocks can react differently to issuer, political, market and economic developments than the market as a whole and other types of stocks. 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. 

Mid-Sized Companies.  The Adviser believes there is more potential for capital appreciation in mid-sized companies, but there also may be more risk. Securities of 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 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. Mid-sized companies rely more on the skills of management and on their continued tenure. Investing in 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. 

Technology.  Technology companies, including internet-related and information technology companies, as well as companies propelled by new technologies, may present the risk of rapid change and product obsolescence, and their successes may be difficult to predict for the long term. Some technology companies may be newly formed and have limited operating history and experience. Technology companies may also be adversely affected by changes in governmental policies, competitive pressures and changing demand. The securities of these companies may also experience significant price movements caused by disproportionate investor optimism or pessimism, with little or no basis in the companies’ fundamentals or economic conditions. 

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund (Retail Shares) by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for 1, 5 and 10 years and since inception compare with those of two broad measures of market performance. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available online at www.BaronFunds.com/performance or by calling 1-800-99BARON (1‑800‑992‑2766).

The following table shows the Fund’s Retail Shares’ annual returns and long-term performance (before and after taxes) and the change in value of broad-based market indexes over various periods ended December 31, 2021. The table also shows the average annual returns of the Fund’s Institutional Shares and R6 Shares, but it does not show after-tax returns.

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.

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’s shares in a tax-deferred account (including a 401(k) or IRA or Coverdell account), or to investors that are tax-exempt.

If the annual returns for the Institutional Shares and R6 Shares prior to May 29, 2009 did not reflect this fee, the returns would be higher.

Tax Information

Distributions of the Fund’s net investment income (other than “qualified dividend income”) and distributions of net short-term capital gains will be taxable to you as ordinary income.

Baron Small Cap Fund

Investment Goal

The investment goal of Baron Small Cap Fund (the “Fund”) is capital appreciation through investments primarily in securities of small-sized growth companies.

Fees and Expenses of the Fund

The table below describes the fees and expenses that you would pay if you bought and held shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below.

Annual Fund Operating Expenses

(Expenses that you pay each year as a percentage of the value of your investment)

	Management Fee		Distribution (12b-1) Fee		Other Expenses		Total Annual Fund Operating Expenses
BARON SMALL CAP FUND
Retail Shares		1.00%		0.25%		0.04%		1.29%

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

R6 Shares	$	106	$	331	$	574	$	1,271

Portfolio Turnover.  The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes for Fund shareholders. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the example, affect the Fund’s performance. During the most recent fiscal year ended September 30, 2021, the Fund’s portfolio turnover rate was 15.70% of the average value of its portfolio.

Investments, Risks, and Performance

Principal Investment Strategies of the Fund

The Fund is a diversified fund that invests 80% of its net assets in equity securities in the form of common stock of U.S. small-sized growth companies. BAMCO, Inc. (“BAMCO” or the “Adviser”) defines small-sized companies as those, at the time of purchase, with market capitalizations up to the largest market cap stock in the Russell 2000 Growth Index at reconstitution, or companies with market capitalizations up to $2.5 billion, whichever is larger. The Adviser seeks to invest in businesses it believes have significant opportunities for growth, sustainable competitive advantages, exceptional management, and an attractive valuation. Because of its long-term approach, the Fund could have a significant percentage of its assets invested in securities that have appreciated beyond their market capitalizations at the time of the Fund’s investment.

Principal Risks of Investing in the Fund

General Stock Market.  Fund losses may be incurred due to declines in one or more markets in which Fund investments are made. 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 caused, among other reasons, by increased inflation, or tightening monetary policy or interest rate increases by the US Federal Reserve or similar international bodies, and reduced liquidity in financial markets may negatively affect many issuers, which could have an adverse effect on your Fund investment. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers worldwide. As a result, local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions or other events could have a significant negative impact on global economic and market conditions. The coronavirus disease 2019 (COVID-19) global pandemic and the aggressive responses taken by many governments or voluntarily imposed by private parties, including closing borders, restricting travel and imposing 

1-800-99BARON 19

Baron Small Cap Fund

prolonged quarantines or similar restrictions, as well as the closure of, or operational changes to, many retail and other businesses, have had negative impacts, and in many cases severe negative impacts, on markets worldwide. It is not known how long such impacts, or any future impacts of other significant events described above, will or would last, but there could be a prolonged period of global economic slowdown, which may impact your Fund investment. 

Growth Investing.  Growth stocks can react differently to issuer, political, market and economic developments than the market as a whole and other types of stocks. 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. 

Small-Sized Companies.  The Adviser believes there is more potential for capital appreciation in small-sized companies, but there also may be more risk. Securities of small-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‑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-sized companies rely more on the skills of management and on their continued tenure. Investing in small-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. 

Special Situations.  The Funds may invest in “special situations.” A special situation arises when, in the opinion of the Adviser, the securities of a company will be recognized and appreciate in value due to a specific anticipated development at that company. Such developments might include a new product, a management change, an acquisition or a technological advancement. The risk of investing in special situations is that the anticipated development does not occur or its impact is not what the Adviser expected. 

Technology.  Technology companies, including internet-related and information technology companies, as well as companies propelled by new technologies, may present the risk of rapid change and product obsolescence, and their successes may be difficult to predict for the long term. Some technology companies may be newly formed and have limited operating history and experience. Technology companies may also be adversely affected by changes in governmental policies, competitive pressures and changing demand. The securities of these companies may also experience significant price movements caused by disproportionate investor optimism or pessimism, with little or no basis in the companies’ fundamentals or economic conditions.

The following bar chart and table provide some indication of the risks of investing in the Fund (Retail Shares) by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for 1, 5 and 10 years and since inception compare with those of two broad measures of market performance. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

The following table shows the Fund’s Retail Shares’ annual returns and long-term performance (before and after taxes) and the change in value of broad-based market indexes over various periods ended December 31, 2021. The table also shows the average annual returns of the Fund’s Institutional Shares and R6 Shares, but it does not show after-tax returns.

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.

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’s shares in a tax-deferred account (including a 401(k) or IRA or Coverdell account), or to investors that are tax-exempt.

These costs, which are not reflected in Total Annual Fund Operating Expenses or in the example, affect the Fund’s performance. During the most recent fiscal year ended September 30, 2021, the Fund’s portfolio turnover rate was 15.87% of the average value of its portfolio.

Investments, Risks, and Performance

Principal Investment Strategies of the Fund

The Fund is a diversified fund that invests primarily in equity securities in the form of common stock of U.S. large-sized growth companies. The Adviser defines large‑sized companies as those, at the time of purchase, with market capitalizations no smaller than the top 85^th percentile by total market capitalization of the Russell 1000 Growth Index at June 30, or companies with market capitalizations above $10 billion, whichever is smaller. The Adviser seeks to invest in businesses it believes have significant opportunities for growth, sustainable competitive advantages, exceptional management, and an attractive valuation.

Principal Risks of Investing in the Fund

General Stock Market.  Fund losses may be incurred due to declines in one or more markets in which Fund investments are made. 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 caused, among other reasons, by increased inflation, or tightening monetary policy or interest rate increases by the US Federal Reserve or similar international bodies, and reduced liquidity in financial markets may negatively affect many issuers, which could have an adverse effect on your Fund investment. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market 

34 www.BaronFunds.com

Baron Fifth Avenue Growth Fund

may adversely impact issuers worldwide. As a result, local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions or other events could have a significant negative impact on global economic and market conditions. The coronavirus disease 2019 (COVID-19) global pandemic and the aggressive responses taken by many governments or voluntarily imposed by private parties, including closing borders, restricting travel and imposing prolonged quarantines or similar restrictions, as well as the closure of, or operational changes to, many retail and other businesses, have had negative impacts, and in many cases severe negative impacts, on markets worldwide. It is not known how long such impacts, or any future impacts of other significant events described above, will or would last, but there could be a prolonged period of global economic slowdown, which may impact your Fund investment. 

Growth Investing.  Growth stocks can react differently to issuer, political, market and economic developments than the market as a whole and other types of stocks. 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. 

Large-Cap Companies.  Because the Fund invests primarily in large-cap company securities, it may underperform other funds during periods when the Fund’s securities are out of favor. 

Technology.  Technology companies, including internet-related and information technology companies, as well as companies propelled by new technologies, may present the risk of rapid change and product obsolescence, and their successes may be difficult to predict for the long term. Some technology companies may be newly formed and have limited operating history and experience. Technology companies may also be adversely affected by changes in governmental policies, competitive pressures and changing demand. The securities of these companies may also experience significant price movements caused by disproportionate investor optimism or pessimism, with little or no basis in the companies’ fundamentals or economic conditions. 

Consumer Discretionary Sector Risk.  The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers’ disposable income, consumer preferences, social trends and marketing campaigns.

The following table shows the Fund’s Retail Shares’ annual returns and long-term performance (before and after taxes) and the change in value of broad-based market indexes over various periods ended December 31, 2021. The table also shows the average annual returns of the Fund’s Institutional Shares and R6 Shares, but it does not show after-tax returns.

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.

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’s shares in a tax-deferred account (including a 401(k) or IRA or Coverdell account), or to investors that are tax-exempt.

Tax Information

Distributions of the Fund’s net investment income (other than “qualified dividend income”) and distributions of net short-term capital gains will be taxable to you as ordinary income.

Investment Goal

The investment goal of Baron Discovery Fund (the “Fund”) is capital appreciation through investments primarily in securities of small-sized growth companies.

Fees and Expenses of the Fund

The table below describes the fees and expenses that you would pay if you bought and held shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same, giving effect to the expense reimbursement agreement described above. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

YEAR	1		3		5		10
BARON DISCOVERY FUND

shareholders. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the example, affect the Fund’s performance. During the most recent fiscal year ended September 30, 2021, the Fund’s portfolio turnover rate was 36.52% of the average value of its portfolio.

Investments, Risks, and Performance

Principal Investment Strategies of the Fund

The Fund is a diversified fund that invests for the long term primarily in equity securities in the form of common stock of U.S. small-sized growth companies. The Adviser defines small-sized companies as those, at the time of purchase, with market capitalizations up to the largest market cap stock in the Russell 2000 Growth Index at reconstitution, or companies with market capitalizations up to $2.5 billion, whichever is larger. The Adviser seeks to invest in businesses it believes have significant opportunities for growth, sustainable competitive advantages, exceptional management, and an attractive valuation. Because of its long-term approach, the Fund could have a significant percentage of its assets invested in securities that have appreciated beyond their market capitalizations at the time of the Fund’s investment.

Principal Risks of Investing in the Fund

General Stock Market.  Fund losses may be incurred due to declines in one or more markets in which Fund investments are made. 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 caused, among other reasons, by increased inflation, or tightening monetary policy or interest rate increases by the US Federal Reserve or similar international bodies, and reduced liquidity in financial markets may negatively affect many issuers, which could have an adverse effect on your Fund investment. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers worldwide. As a result, local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions or other events could have a significant negative impact on global economic and market conditions. The coronavirus disease 2019 (COVID-19) global pandemic and the aggressive responses taken by many governments or voluntarily imposed by private parties, including closing borders, restricting travel and imposing prolonged quarantines or similar restrictions, as well as the closure of, or operational changes to, many retail and other businesses, have had negative impacts, and in many cases severe negative impacts, on markets worldwide. It is not known how long such impacts, or any future impacts of other significant events described above, will 

42 www.BaronFunds.com

Baron Discovery Fund

or would last, but there could be a prolonged period of global economic slowdown, which may impact your Fund investment. 

Growth Investing.  Growth stocks can react differently to issuer, political, market and economic developments than the market as a whole and other types of stocks. 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. 

Small-Sized Companies.  The Adviser believes there is more potential for capital appreciation in small-sized companies, but there also may be more risk. Securities of small-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-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-sized companies rely more on the skills of management and on their continued tenure. Investing in small-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. 

Special Situations.  The Funds may invest in “special situations.” A special situation arises when, in the opinion of the Adviser, the securities of a company will be recognized and appreciate in value due to a specific anticipated development at that company. Such developments might include a new product, a management change, an acquisition or a technological advancement. The risk of investing in special situations is that the anticipated development does not occur or its impact is not what the Adviser expected. 

Health Care Sector Risk.  Investments in health care companies are subject to a number of risks, including the adverse impact of legislative actions and government regulations. 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’s transition from development to production, or erratic revenue patterns. The stock prices of these companies are very volatile, particularly when their products are up for regulatory approval and/or under regulatory scrutiny.

¹  BAMCO, Inc. (“BAMCO” or the “Adviser”) has agreed that, pursuant to a contract with an 11-year term terminating on August 29, 2032, it will reimburse certain expenses of the Fund, limiting net annual operating expenses (portfolio transaction costs, interest, dividend, acquired fund fees and expenses and extraordinary expenses are not subject to the operating expense limitation) to 0.95% of average daily net assets of Retail Shares, 0.70% of average daily net assets of Institutional Shares and 0.70% of average daily net assets of R6 shares. Only the Board of Trustees of the Fund may terminate the expense reimbursement agreement prior to its termination date.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a

5% return each year and that the Fund’s operating expenses remain the same, giving effect to the expense reimbursement agreement described above. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Retail Shares	$	97	$	303	$	525	$	1,166
Institutional Shares	$	72	$	224	$	390	$	871
R6 Shares	$	72	$	224	$	390	$	871

Portfolio Turnover.  The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes for Fund shareholders. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the example, affect the Fund’s performance. During the most recent fiscal year ended September 30, 2021, the Fund’s portfolio turnover rate was 10.58% of the average value of its portfolio.

Investments, Risks, and Performance

Principal Investment Strategies of the Fund

The Fund is a diversified fund that invests primarily in equity securities in the form of common stock of U.S. large‑sized companies. The Adviser defines large‑sized companies as those, at the time of purchase, with market capitalizations no smaller than the top 90^th percentile by total market capitalization of the S&P 500 Index at June 30, or companies with market capitalizations above $10 billion, whichever is smaller. The Adviser seeks to invest primarily in what it believes are unique, well-managed, competitively advantaged businesses that generate significant excess free cash flow that is consistently returned to shareholders in the form of stock buybacks and/or dividends.

Principal Risks of Investing in the Fund

General Stock Market.  Fund losses may be incurred due to declines in one or more markets in which Fund investments are made. 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 caused, among other reasons, by increased inflation, or tightening monetary policy or interest rate increases by the US Federal Reserve or similar international bodies, and reduced liquidity in financial markets may negatively affect many issuers, which could have an adverse effect on 

50 www.BaronFunds.com

Baron Durable Advantage Fund

your Fund investment. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers worldwide. As a result, local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions or other events could have a significant negative impact on global economic and market conditions. The coronavirus disease 2019 (COVID-19) global pandemic and the aggressive responses taken by many governments or voluntarily imposed by private parties, including closing borders, restricting travel and imposing prolonged quarantines or similar restrictions, as well as the closure of, or operational changes to, many retail and other businesses, have had negative impacts, and in many cases severe negative impacts, on markets worldwide. It is not known how long such impacts, or any future impacts of other significant events described above, will or would last, but there could be a prolonged period of global economic slowdown, which may impact your Fund investment. 

Large‑Cap Companies.  Because the Fund invests primarily in large‑cap company securities, it may underperform other funds during periods when the Fund’s securities are out of favor. 

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund (Retail Shares) by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for 1 year and since inception compare with those of a broad measure of market performance. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available online at www.BaronFunds.com/performance or by calling 1‑800‑99BARON (1‑800‑992‑2766).

Average Annual Total Returns (for periods ended 12/31/21)

The following table shows the Fund’s Retail Shares’ annual returns and long-term performance (before and after taxes) and the change in value of a broad-based market index over various periods ended December 31, 2021. The table also shows the average annual returns of the Fund’s Institutional Shares and R6 Shares, but it does not show after‑tax returns.

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.

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’s shares in a tax‑deferred account (including a 401(k) or IRA or Coverdell account), or to investors that are tax‑exempt.

Additional Investment Strategies

The following is a description of additional investment strategies of Baron Asset Fund, Baron Growth Fund, Baron Small Cap Fund, Baron Opportunity Fund,

56 www.BaronFunds.com

Information about the Funds Baron Funds^®

Baron Fifth Avenue Growth Fund, Baron Discovery Fund and Baron Durable Advantage Fund (each, a “Fund” and collectively, the “Funds”).

The Funds may invest without limitation in the securities of non-U.S. issuers in U.S. denominated form known as American Depository Receipts. They may also invest up to 10% of the respective total assets of Baron Asset Fund, Baron Growth Fund and Baron Small Cap Fund, and up to 25% of the respective total assets of Baron Opportunity Fund, Baron Fifth Avenue Growth Fund, Baron Discovery Fund and Baron Durable Advantage Fund directly in the securities of non-U.S. issuers that are not publicly traded in the U.S. and in Global Depository Receipts and European Depository Receipts. These securities may have exposure to developed countries and developing countries, which 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.

Except for Baron Asset Fund, the Funds may also sell securities short. Short selling occurs when the Funds sell a security that the Funds do not own. In order to do so, the Funds must borrow a security to deliver it to the purchaser and later buy that security in the market and return it to the lender. The Funds may establish short positions in securities that the Adviser believes have limited growth prospects or are over-priced, or in securities of companies the Adviser believes are poorly managed or have highly leveraged balance sheets. The Funds may also establish a short position in a security to hedge exposure to a particular company or to hedge exposure to a certain industry or sector of the market. The Funds may also short market indices to hedge against broad movements in the market. Generally, when the Funds take a short position, the Adviser believes that the security’s price will fall. If it falls sufficiently, the Funds will make money. If it instead increases in price, the Funds will lose money. The Funds will not use more than 35% of their respective total assets in maintaining short positions. The Adviser, in its sole discretion, may decide not to sell any securities short. The Adviser believes that the flexibility to execute a long and short strategy may reduce the short-term volatility inherent in the equity markets. However, the Adviser also believes short sales can be significantly more risky than long investments and, as a result, expects to employ this tactic relatively infrequently.

Baron Asset Fund may invest up to 10% of its net assets, and Baron Growth Fund, Baron Small Cap Fund, Baron Opportunity Fund, Baron Fifth Avenue Growth Fund, Baron Discovery Fund and Baron Durable Advantage Fund may invest up to 15%, of their respective net assets in illiquid securities at the time of purchase. Subsequently, if as a result of changes in the portfolio, illiquid securities exceed 10 or 15% of net assets (as applicable), a Fund may not acquire any additional illiquid securities and the Adviser will take such steps as it considers appropriate to reduce

1-800-99BARON 57

Information about the Funds Baron Funds^®

the percentage within a reasonable period of time. An illiquid security is one that a Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the security. Such investments may include private equity securities, private investments in public equity (“PIPE”) securities and other restricted securities.

The Funds may invest in debt securities of all types and repurchase agreements for those securities. Debt securities include corporate bonds, government securities, repurchase agreements, loans and loan participations, mortgage-backed securities and other securities that the Funds believe have debt-like characteristics, including hybrids and synthetic securities. Debt securities are used by issuers to borrow money. The issuer usually pays a fixed, variable, or floating rate of interest, and must repay the amount borrowed, usually at the maturity of the security. Some debt securities, such as zero coupon bonds, do not pay current interest but are sold at a discount from their face values. The Funds may invest in debt securities that have a rating of, or equivalent to, at least “BBB” by Standard & Poor’s Corporation or “Baa” by Moody’s Investors Services, Inc., or if unrated, are judged by the Adviser to be of comparable quality. Except for Baron Small Cap Fund, which may invest up to 20% of its total assets, the Funds may invest up to 35% of their total assets in such securities. Some debt securities purchased by the Funds may have very long maturities. The length of time remaining until maturity is one factor that the Adviser considers in purchasing a particular debt security.

The Funds may, from time to time, take temporary defensive positions that are inconsistent with the Funds’ principal investment strategies in attempting to respond to adverse market, economic, political, or other conditions. In such circumstances, the Adviser may invest all or a portion of the Funds’ assets in cash or cash equivalents, such as money market instruments, which include U.S. Government securities, certificates of deposit, short-term investment grade corporate bonds and other short term debt instruments, and repurchase agreements. Taking such a temporary defensive position may cause the Funds not to achieve their investment goals. Baron Asset Fund may borrow up to 5% of its net assets for extraordinary or emergency temporary investment purposes or to meet redemption requests that might otherwise require an untimely sale of portfolio securities. Baron Growth Fund, Baron Small Cap Fund and Baron Opportunity Fund may borrow up to 30% of the value of their respective total assets, including the amount borrowed, as of the time the borrowing is made, for temporary, emergency or other purposes. Baron Fifth Avenue Growth Fund, Baron Discovery Fund and Baron Durable Advantage Fund may borrow money to the extent permitted by law (which currently requires asset coverage of 300% immediately after such borrowing).

Companies in which the Funds invest may be subject to corporate actions, including mergers and acquisitions. The Adviser may, in its discretion, choose to receive shares

58 www.BaronFunds.com

Information about the Funds Baron Funds^®

of the combined entity where it concludes that it is in the best interest of the Funds’ shareholders to do so. Such a decision may result in the Funds owning shares of an issuer outside of the Funds’ market cap range.

The Funds may enter into swap transactions.

The Funds have additional investment strategies and restrictions that govern their activities. For a list of these restrictions and more information about the investment strategies, please see the “Investment Strategies and Risks” section beginning on page 3 of the Statement of Additional Information (“SAI”). Those strategies and restrictions that are identified as “fundamental” may only be changed with shareholder approval, while the others may be changed by the Board of Trustees (the “Board”) without shareholder approval upon at least 60 days’ notice.

Investment Criteria and Process

In making investment decisions for Baron Funds^®, the Adviser seeks to invest in businesses that it believes have:

1. significant opportunities for growth;

2. sustainable competitive advantages;

3. exceptional management; and

4. an attractive valuation.

The Adviser’s research process includes examining companies from many perspectives through numerous interviews with company managements and site visits. The Adviser also interviews a company’s employees, as well as its customers, suppliers, and competitors to determine whether the information gained from these parties is consistent with senior management’s objectives and the Adviser’s independent findings. Through these and other inquiries, the Adviser becomes an expert in the industries in which it invests and acquires a thorough understanding of the prospects of its investments in their competitive landscape. The Adviser also studies industry data, statistics and trends. The Adviser invests without regard for market trends.

The Funds purchase stocks that the Adviser believes are attractively priced relative to the Adviser’s projections of intrinsic value. The most critical component of the Adviser’s investment decisions is the quality of a company, as measured by its growth prospects, management, business model, competitive position, capital structure and valuation. In building its portfolios, the Adviser does not use a market benchmark, nor does it aim to underweight or overweight any sectors or industries. The Adviser seeks to invest in businesses before their long-term growth prospects are appreciated by other investors. The Funds may make significant investments in companies in which

1-800-99BARON 59

Information about the Funds Baron Funds^®

the Adviser has great conviction. Of course, there can be no guarantee that the Funds will be successful at achieving their investment goals.

The Funds have a long-term outlook and often invest in businesses for several years. The Funds hope for significant business growth and stock price appreciation over that time period. As long-term investors in businesses, the Funds are designed for long-term shareholders. The Funds are not designed, or intended to be suitable, for investors who intend to purchase and then sell their Fund shares within a 90 day period (please see the “Policies Regarding Frequent Purchases and Redemptions of Fund Shares” section on pages 79-81 of this Prospectus).

Additional Investment Risks

Consumer Discretionary Sector Risk.  The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers’ disposable income, consumer preferences, social trends and marketing campaigns.

Credit and Interest Rate Risk.  The market value of debt securities is affected by changes in prevailing interest rates and the perceived credit quality of the issuer. When prevailing interest rates fall or perceived credit quality improves, the market value of the affected debt securities generally rises. Conversely, when interest rates rise or perceived credit quality weakens, the market value of the affected debt securities generally declines. The risks associated with rising interest rates may be heightened as interest rates in the U.S. and elsewhere are at or near historic lows. The magnitude of these fluctuations will be greater when the maturity of the debt securities is longer.

Currency Risk.  This refers to a decline in the value of a foreign currency versus the U.S. dollar, which reduces the dollar value of securities denominated in that currency. The overall impact on the Funds’ 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 Funds do not engage in extensive foreign currency hedging programs. Further, exchange rate movements are volatile, the Funds’ attempts at hedging could be unsuccessful, and it may not be to effectively hedge the currency risks of many developing countries.

Cybersecurity Risk.  The use of the Internet and other electronic media and technology exposes the Funds, and the Funds’ service providers, and their respective operations, to potential risks from cybersecurity attacks or incidents (collectively, “cyber incidents”). Cyber incidents may include, for example, unauthorized access to systems, networks or devices (such as, for example, through “hacking” activity), infection from computer viruses or other malicious software code, and attacks which

60 www.BaronFunds.com

Information about the Funds Baron Funds^®

shut down, disable, slow or otherwise disrupt operations, business processes or website access or functionality. In addition to intentional cyber incidents, unintentional cyber incidents can occur, such as, for example, the inadvertent release of confidential information. Any cyber incident could adversely impact the Funds and their shareholders and cause the Funds to incur financial loss and expense, as well as face exposure to regulatory penalties, reputational damage, and additional compliance costs associated with corrective measures. A cyber incident may cause the Funds, or their service providers, to lose proprietary information, suffer data corruption, lose operational capacity (such as, for example, the loss of the ability to process transactions, calculate the Funds’ net asset values per share (“NAVs”), or allow shareholders to transact business), and/or fail to comply with applicable privacy and other laws. Among other potentially harmful effects, cyber incidents also may result in theft, unauthorized monitoring and failures in the physical infrastructure or operating systems that support the Funds and their service providers. In addition, cyber incidents affecting issuers in which the Funds invest could cause the Funds’ investments to lose value. The Adviser has established risk management systems reasonably designed to seek to reduce the risks associated with cyber incidents. However, there is no guarantee that the efforts of the Adviser or its affiliates, or other service providers, will succeed, either entirely or partially. The nature of malicious cyber attacks is becoming increasingly sophisticated and the Funds and the Adviser, and its relevant affiliates, cannot control the cyber systems and cybersecurity systems of issuers or third party service providers.

Developing Countries.  The Funds invest in developing countries, which 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. These risks are greater for countries in the FM Index.

General Stock Market.  Fund losses may be incurred due to declines in one or more markets in which Fund investments are made. 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 caused, among other reasons, by increased inflation, or tightening monetary policy or interest rate increases by the US Federal Reserve or similar international bodies, and reduced liquidity in financial markets may negatively affect many issuers, which could have an adverse effect on

1-800-99BARON 61

Information about the Funds Baron Funds^®

your Fund investment. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies worldwide. As a result, local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions or other events could have a significant negative impact on global economic and market conditions. The coronavirus disease 2019 (COVID-19) global pandemic and the aggressive responses taken by many governments or voluntarily imposed by private parties, including closing borders, restricting international and domestic travel and imposing prolonged quarantines or similar restrictions, as well as the closure of, or operational changes to, many retail and other businesses, have had negative impacts, and in many cases severe negative impacts, on markets worldwide. It is not known how long such impacts, or any future impacts of other significant events described above, will or would last, but there could be a prolonged period of global economic slowdown, which may impact your Fund investment.

Growth Investing.  Growth stocks can react differently to issuer, political, market and economic developments than the market as a whole and other types of stocks. 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.

Health Care Sector Risk.  Investments in health care companies are subject to a number of risks, including the adverse impact of legislative actions and government regulations. 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’s transition from development to production, or erratic revenue patterns. The stock prices of these companies are very volatile, particularly when their products are up for regulatory approval and/or under regulatory scrutiny.

Illiquid Securities.  Illiquid securities, which include securities that are not publicly traded such as private equity securities, PIPE securities and other restricted securities, may be difficult to sell or may be subject to agreements that prohibit or limit their sale or other disposition. This investment approach requires a long-term outlook and

62 www.BaronFunds.com

Information about the Funds Baron Funds^®

may involve more risk. Baron Asset Fund may invest up to 10% of its net assets, and Baron Growth Fund, Baron Small Cap Fund, Baron Opportunity Fund, Baron Fifth Avenue Growth Fund, Baron Discovery Fund and Baron Durable Advantage Fund may invest up to 15% of their respective net assets in illiquid securities at the time of purchase. Subsequently, if as a result of changes in the portfolio, illiquid securities exceed 10 or 15% of net assets (as applicable), a Fund may not acquire any additional illiquid securities and the Adviser will take such steps as it considers appropriate to reduce the percentage within a reasonable period of time. An illiquid security is one that a Fund reasonably expects to be unable to sell or dispose of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the security.

Initial Public Offerings.  The prices of securities purchased in initial public offerings (“IPOs”) can be very volatile and/or decline shortly after the IPO. Securities issued in IPOs have no trading history, and information about the issuing companies may be available for only very limited periods. The effect of IPOs on a Fund’s performance depends on a variety of factors, including the number of IPOs the Fund invests in relative to the size of the Fund and whether and to what extent a security purchased in an IPO appreciates or depreciates in value. If a Fund’s historical performance was impacted by gains from IPOs and/or secondary offerings, there is no guarantee that these results can be repeated or that a Fund’s level of participation in IPOs and secondary offerings will be the same in the future.

Large-Cap Companies.  Because a Fund may invest primarily in large-cap company securities, that Fund may underperform other funds during periods when their securities are out of favor.

Large Positions.  The Funds may establish relatively large positions in companies in which the Adviser has great conviction. Movement in the prices of securities in which the Funds hold large positions could have a significant impact on the Funds’ NAVs. These large positions may represent a significant part of a company’s outstanding stock, and sales by the Funds or a Fund could adversely affect stock prices. A Fund’s returns may be more volatile than those of a fund that does not establish large positions.

Long-Term Outlook and Projections.  The Funds are designed for long-term investors who are willing to hold investments for a substantial period of time. The cash flows and valuations that the Adviser projects for a company may not be achieved, which could negatively affect the impact of that stock in the Funds’ portfolios.

Non-U.S. Securities.  Investments in non-U.S. securities may involve additional risks to those inherent in investments in U.S. securities, including exchange rate fluctuations, political or economic instability, the imposition of exchange controls, expropriation, limited disclosure and illiquid markets. Risks can result from varying stages of economic and political development, differing regulatory environments,

1-800-99BARON 63

Information about the Funds Baron Funds^®

trading days, and accounting standards, uncertain tax laws, and higher transaction costs of non-U.S. markets. Investments outside the United States could be subject to governmental actions such as capital or currency controls, nationalization of a company or industry, expropriation of assets, or imposition of high taxes. Trading in the underlying securities of the Funds may take place in various foreign markets on certain days when the Funds are not open for business and do not calculate NAVs. As a result, NAVs may be significantly affected on days when shareholders cannot make transactions.

Prepayment.  Many types of debt securities are subject to prepayment risk. Prepayment risk occurs when the issuer of a security can repay principal prior to the security’s maturity. Securities subject to prepayment can offer less potential for gains during a declining interest rate environment and similar or greater potential for loss in a rising interest rate environment. In addition, the potential impact of prepayment features on the price of a debt security can be difficult to predict and result in greater volatility.

Risks of Emphasizing a Region, Country, Sector or Industry.  If a Fund has invested a higher percentage of its total assets in a particular region, country, sector or industry, changes affecting that region, country, sector or industry may have a significant impact on the performance of that Fund’s overall portfolio. The economies and financial markets of certain regions — such as Latin America, Asia, and Europe and the Mediterranean region — can be interdependent and may all decline at the same time.

Short Sales.  If the price of the stock sold short increases after the sale, the Funds will lose money because they will have to pay a higher price to repurchase the borrowed stock when they close their short position. The Funds may not be able to close out a short position at an acceptable price or time and the loss of value on a short sale is theoretically unlimited. The Funds have to borrow the securities to enter into the short sale. If the lender demands the securities be returned, the Fund must deliver them promptly, either by borrowing from another lender or buying the securities. If this occurs at the same time other short-sellers are trying to borrow or buy the securities, a “short squeeze” could occur, causing the stock price to rise and making it more likely that the Funds will have to cover their short positions at an unfavorable price. This could happen regardless of whether or not the prospects for a business are favorable or unfavorable.

Small- and Mid-Sized Companies.  The Adviser believes there is more potential for capital appreciation in small- and mid-sized companies, but there also may be more risk. 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

64 www.BaronFunds.com

Information about the Funds Baron Funds^®

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.

Specific Securities.  Earnings, cash flows and valuations projected by the Adviser for a long position may not be achieved, which could negatively affect the impact of that stock in a Fund’s portfolio. With respect to a short position held by a Fund, the company or the securities markets may have favorable developments or news that positively affect the stock market price of that company, which in turn, could result in a loss for the Fund.

Swaps.  The Funds may enter into equity swap transactions. Equity swap transactions are entered into with financial intermediaries through a direct agreement with the counterparty, generally an ISDA Master Agreement, the specific terms of which are negotiated by the parties. The Funds may use equity swaps, or other derivative instruments, for hedging purposes against potential adverse movements in security prices or for non-hedging purposes such as seeking to enhance return. The Funds may be required to post collateral for such transactions. There is no central clearing or, unless the parties provide for it, guaranty function in an over-the-counter option or derivative, including certain swaps. As a result, if the counterparty fails to make or take delivery of the security or other instrument, or fails to make a cash settlement payment due in accordance with the option, the Funds will lose any premium they paid for the option as well as any anticipated benefit of the transaction.

Taxes.  Each of the Funds has elected to be treated, and intends to qualify each year, as a “regulated investment company” under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”). To qualify for the special U.S. federal income tax treatment afforded to regulated investment companies, each Fund must meet certain source-of-income, asset diversification and annual distribution requirements, as discussed in the “U.S. Federal Income Taxation” section on pages 83-85 of this Prospectus. If for any taxable year a Fund fails to qualify for the special U.S. federal income tax treatment afforded to regulated investment companies, all of the Fund’s taxable income will be subject to federal income tax at regular corporate rates (without any deduction for distributions to the Fund’s shareholders) and the Fund’s income available for distribution will be reduced. (Please see the “U.S. Federal Income Taxation” section on pages 83-85 of this Prospectus, and the “Taxation of the Funds” section on pages 40-46 in the SAI.)

Technology.  Technology companies, including internet-related and information technology companies, as well as companies propelled by new technologies, may present the risk of rapid change and product obsolescence, and their successes may be

1-800-99BARON 65

Information about the Funds Baron Funds^®

difficult to predict for the long term. Some technology companies may be newly formed and have limited operating history and experience. Technology companies may also be adversely affected by changes in governmental policies, competitive pressures and changing demand. The securities of these companies may also experience significant price movements caused by disproportionate investor optimism or pessimism, with little or no basis in the companies’ fundamentals or economic conditions.

Share Classes

The Funds offer three classes of shares, Retail Shares, Institutional Shares and R6 Shares, which differ only in their ongoing fees and eligibility requirements. Retail Shares are available to all investors, and investment minimums range from $500 to $2,000 per Fund, depending on the account type. Institutional Shares are for investments in the amount of $1,000,000 or more per Fund.

How Your Shares are Priced

The Funds’ share prices or NAVs are calculated as of the scheduled close of the regular trading session (usually 4 p.m. E.T. or such other time as of which the Funds’ NAVs are calculated (the “NAV Calculation Time”)) on the New York Stock Exchange (the “Exchange”) on any day the Exchange is scheduled to be open. Your purchase or sale will be priced at the next NAV calculated after your order is accepted by DST Systems, Inc. (the “Transfer Agent”). The Funds may change the time at which orders are priced if the Exchange closes at a different time or an emergency exists. The Exchange is closed on weekends and most national holidays, including New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The NAVs will not be calculated on days when the Exchange is closed for trading. Foreign securities held by the Funds may trade on days when the Funds do not calculate their NAVs and thus may affect the Funds’ NAVs on days when investors will not be able to purchase or sell (redeem) Funds’ shares. The Funds have agreements with certain financial intermediaries that authorize them to accept orders or designate third parties to accept orders on behalf of the Funds. If you place your order through these financial intermediaries, the order will be considered received when they accept the order. Those orders will be priced at the next NAV calculated after acceptance of the order by the financial intermediary or its agent.

Portfolio securities traded on any national exchange are valued based on their last sale price on the exchange where such shares are principally traded. For securities traded on NASDAQ, the Funds use the NASDAQ Official Closing Price. If there are no sales on a given day, the value of the security may be the average of the most recent bid and asked quotations on such exchange or the last sale price from a prior day. Where market quotations are not readily available, or, if in the Adviser’s judgment, they do not accurately reflect the fair value of a security, or an event occurs after the market close but before the Funds are priced that materially affects the value of a security, the security will be valued by the Adviser using policies and procedures approved by the Board. The Adviser has a Fair Valuation Committee (the “Committee”) comprised of senior management representatives and the Committee reports to the Board every quarter. Factors the Committee may consider when valuing a security include whether a current price is stale, there is recent news, the security is thinly traded, transactions are infrequent or quotations are genuine. There can be no guarantee, however, that a fair valuation used by the Funds on any given day will more accurately reflect the market value of an investment than the closing price of such investment in its market.

U.S. Government obligations and other debt instruments having 60 days or less remaining until maturity are valued at amortized cost. Debt instruments

70 www.BaronFunds.com

Information about your Investment Baron Funds^®

having a greater remaining maturity will be valued on the basis of prices obtained from an independent pricing service or at the mean of the bid and ask prices from a dealer maintaining an active market in that security. The value of the Funds’ investments in convertible bonds is determined primarily by obtaining valuations from independent pricing services based on readily available bid quotations or, if quotations are not available, by methods which include various considerations such as yields or prices of securities of comparable quality, coupon, maturity and type; indications as to values from dealers; and general market conditions. Other inputs used by an independent pricing service to value convertible bonds generally include underlying stock data, conversion premiums, listed bond and preferred stock prices and other market information which may include benchmark curves, trade execution data, and sensitivity analysis, when available. Open-end investment companies, including securities lending collateral invested in registered investment company money market funds, are valued at their NAV each day.

Non-U.S. equity securities are valued on the basis of their most recent closing market prices and translated into U.S. dollars at the NAV Calculation Time, except under the circumstances described below. Most foreign markets close before the NAV Calculation Time. For securities primarily traded in the Far East, for example, the most recent closing prices may be as much as 15 hours old at the NAV Calculation Time. As a result, the Adviser uses a third-party pricing service to assist in determining fair value of foreign securities. This service utilizes a systematic methodology in making fair value estimates. The Adviser may also fair value securities in other situations, for example, when a particular foreign market is closed but the Funds are open. The Adviser cannot predict how often it will use closing prices or how often it will adjust those prices. As a means of evaluating its fair value process, the Adviser routinely compares closing market prices, the next day’s opening prices in the same markets, and the adjusted prices. Other mutual funds may adjust the prices of their securities by different amounts.

Baron WealthBuilder Fund, employees/Directors of the Adviser and its affiliates and Trustees of the Baron Funds^® and employer sponsored retirement plans (qualified and non-qualified) are not subject to the eligibility requirements for Institutional Shares. R6 Shares are available only to qualified 401(a) plans (including 401(k) plans, Keogh plans, profit-sharing plans, money purchase pension plans, target benefit plans, defined benefit pension plans and Taft-Hartley multi-employer pension plans) (collectively, “Qualified Plans”), endowment funds and foundations, any state, county or city, or its instrumentality, department, authority, or agency, 403(b) plans, 457 plans, including 457(a) governmental entity plans and tax-exempt plans, accounts registered to insurance companies, trust companies and bank trust departments, investment companies, both affiliated and not affiliated with the Adviser, and any entity that is considered a corporation for tax purposes, including corporate non-qualified deferred compensation plans of such corporations. R6 Shares are not available to traditional and Roth Individual Retirement Accounts, SEPs, SARSEPs and individual 403(b) plans. Institutional Shares are available to such accounts or plans to the extent they are purchased through an eligible fee-based program. R6 Shares are also not available to retail, advisory fee-based wrap programs or to adviser-sold donor-advised funds. There is no minimum initial investment for Qualified Plans; however, the shares must be held through plan-level or omnibus accounts held on the books of the Funds. All other R6 eligible investors must meet a minimum initial investment of at least $5,000,000 per Fund.

At the sole discretion of the Adviser, the initial investment minimum may be waived for certain investors. In addition, the Funds will not enforce the minimum for accounts opened through certain financial intermediaries and administrators that may not have systems that are able to enforce the Funds’ minimum. There is no minimum for subsequent purchases except for purchases made through the Funds’ website (please see the “Special Information About the Baron Funds^® Website” section on pages 82-83 of this Prospectus). The Funds may reject any proposed purchase if the purchase would violate the Funds’ policies on short-term trading (please see the “Policies Regarding Frequent Purchases and Redemptions of Fund Shares” section on pages 79-81 of this Prospectus).

Anti-Money Laundering Regulations.  As part of the Funds’ legal responsibility to fight the funding of terrorism and money laundering activities, the Funds require a detailed verification of the identity of a shareholder and individuals with authority or control over accounts opened by entities such as corporations, partnerships or trusts. When you open an account, the Funds will request such information as is necessary to verify your identity as a shareholder, as well as the identities of any individuals with authority or control over accounts being opened by entities. The information requested includes name, address, date of birth and U.S. taxpayer identification number. U.S. military personnel with an APO/FPO address are permitted to invest in the Funds. Please make sure to provide all required information. Incomplete information will delay your investment. The Funds will not process your investment until all required information has been provided. While the Funds are intended for U.S. investors, foreign investors who do not have U.S. taxpayer identification numbers may be permitted to invest in the Funds through a broker-dealer registered with the SEC that has sufficient anti-money laundering policies and procedures in place. The Funds may accept direct investment from foreign investors who do not have U.S. taxpayer identification numbers in the sole discretion of the Adviser.

Your share purchase will receive the NAV of the Funds on the date that all required information has been provided to the Transfer Agent. United Missouri Bank of Kansas City, N.A. will hold your investment check until all required anti-money laundering information has been received. Investment funds received by bank wire will also be held by United Missouri Bank of Kansas City, N.A. If the application is not complete, the Funds’ representatives will attempt to collect any missing information by contacting you directly. If you purchase the Funds through a broker, dealer or other financial intermediary that is subject to the USA PATRIOT Act, such broker, dealer or other financial intermediary will be responsible for collecting the required information.

If the application is complete, the Funds will process the investment and will take steps to verify your identity. The Funds may request additional information or documents, if needed, to verify your identity. If the Funds cannot verify your identity, the account will be closed and you will receive proceeds based on the next NAV calculated for the Fund(s) in which you invested. If the Funds deem it necessary, and upon written notice to you, the payment of redemption proceeds to you may be suspended to comply with the anti-money laundering regulations applicable to the Funds. The Funds will share the identity of their shareholders with federal authorities if required to do so by law and may report a failure to verify a shareholder’s identity with federal authorities in accordance with applicable law.

State Unclaimed Property Laws.  Depending upon the State in which your account is opened, your property may be transferred to the appropriate State if no activity occurs in your account within the time period specified by State law. You should familiarize yourself with the laws of the State in which you have your account.

Through Brokers, Dealers or Other Financial Intermediaries

You may purchase shares of the Funds through a broker, dealer or other financial intermediary that may charge a transaction fee. Such transaction fees may include commissions on brokerage transactions for share classes that do not charge a fee for sales or distribution (e.g., Institutional Shares or R6 Shares). Certain brokers, dealers, or other financial intermediaries may refer to such shares as clean shares. If you purchase shares directly from the Funds, no transaction fee is charged. The Funds also participate in programs with many financial intermediaries where no transaction fee is charged.

How to Redeem Shares

You may redeem Fund shares by any of the methods described below. If you are selling shares in an IRA or Coverdell account, please read the information in the IRA or Coverdell plan document. Redemptions will not be made until all of the requirements are met. Redemptions are priced at the next NAV calculated after your redemption request is received in the proper form. If you have recently purchased shares directly in the Baron Funds^®, your redemption proceeds may not be sent to you until the purchase check has cleared your bank, which generally occurs within fifteen calendar days.

You may receive the proceeds by any one of the following methods: (a) we will mail a check to the address to which your account is registered (usually within seven days); (b) we will transmit the proceeds by electronic funds transfer to a previously designated bank account (usually a two banking day process); or (c) we will wire the proceeds to a pre-authorized bank account for a $10 fee that will be deducted from your redemption proceeds (usually a next banking day process). Banking instructions can be added to your account or changed by sending in a SVP stamped letter of instruction. Please include your account number. Payment of redemption proceeds may take longer than the number of days the Fund typically expects and may take up to seven days after receipt of the redemption request by the Transfer Agent in proper form.

Each Fund will pay in cash all requests for redemption by any Fund shareholder of record, limited in amount with respect to each shareholder during any 90-day period to the lesser of (1) $250,000 or (2) 1% of NAV of the Fund at the beginning of such period. In addition to using cash it holds in its portfolio or selling portfolio securities to generate cash, the Fund may draw upon an unsecured credit facility for temporary or emergency purposes to meet redemption requests. Any additional redemption requests by a shareholder may be satisfied through an in-kind redemption. Generally, a redemption in-kind may be made under the following circumstances: (1) the

76 www.BaronFunds.com

Information about your Investment Baron Funds^®

Adviser determines that a redemption in-kind (i) is more advantageous to the Fund (e.g., due to advantageous tax consequences or lower transaction costs) than selling/purchasing portfolio securities, (ii) will not favor the redeeming shareholder to the detriment of any other shareholder or the Fund and (iii) is in the best interests of the Fund; (2) to manage liquidity risk (i.e., the risk that the Fund could not meet redemption requests without significant dilution of remaining investors’ interests in the Fund); (3) in stressed market conditions; or (4) subject to the approval of the Board in other circumstances identified by the Adviser. Securities distributed in connection with any such redemption in-kind are expected to generally represent a shareholder’s pro rata portion of assets held by the Fund immediately prior to the redemption, with adjustments as may be necessary in connection with, for example, certain derivatives, restricted securities, odd lots or fractional shares. Any securities distributed in-kind will remain exposed to market risk until sold, and a shareholder may incur transaction costs and taxable gain when selling the securities.

By Mail

Please write a letter that includes the following information: the name of the registered owner(s) of the account; the name of the Fund(s); the number of shares or dollar amount to be redeemed; and the account number. The letter must be signed in exactly the same way the account is registered, including the signature of each joint owner, if applicable. Mail the request to the Transfer Agent at Baron Funds^®, P.O. Box 219946, Kansas City, MO 64121-9946.

You will need to have your signature Medallion guaranteed in certain situations (please see the “Special Information About Redemptions” section on pages 78-79 of this Prospectus).

By Telephone

You are automatically granted the telephone redemption option when you open your account, unless you decline the option on your account application or by calling 1‑800‑442‑3814. Once made, your telephone request cannot be changed. There is no minimum amount that you must redeem by telephone from your account. The maximum amount that you may redeem by telephone is $100,000 per Fund per business day.

The Funds have the right to refuse a telephone redemption if they believe that it is advisable to do so. The Funds will not be responsible for any fraudulent telephone order as long as the Funds and their Transfer Agent use reasonable procedures to confirm that telephone instructions are genuine.

A Medallion Signature Guarantee may be obtained from a domestic bank or trust company, broker, dealer, clearing agency, savings association, or other financial institution which participates in a Medallion program recognized by the Securities Transfer Association. Signature guarantees from financial institutions which do not participate in a Medallion program will not be accepted. A notary public cannot provide Medallion Signature Guarantees.

Please call the Transfer Agent at 1-800-442-3814 if you are unsure of any of the special redemption requirements.

The Transfer Agent may require other documentation from corporations, trustees, executors, and others who hold shares on behalf of someone else. If you have any questions concerning the requirements, please call the Transfer Agent at 1-800-442-3814. Redemptions will not be made until all of the conditions, including the receipt in proper

form of all required documentation by the Transfer Agent, have been satisfied. A redemption of Fund shares may generate a tax liability.

For Retail Shares, if the value of your investment in a Fund falls below $2,000 because of redemptions, the Funds may contact you about your balance. If it is still below $2,000 after 60 days, the Funds may redeem the remainder of your investment in the Fund and send you the proceeds. For Institutional Shares, if the value of your investment in a Fund falls below $1,000,000 because of redemptions, the Funds may contact you about your balance. If it remains below $1,000,000 after 60 days, the Funds may convert your Institutional Shares into Retail Shares. The Funds will notify you in writing that your investment will be redeemed or converted in advance of taking such action so that you are informed of the new status of your investment.

The Funds may suspend the normal redemption process if trading on the Exchange is suspended or if an emergency exists that reasonably precludes the valuation of the Funds’ net assets or if the SEC permits a suspension.

Dividends and Distributions

Each Fund pays its shareholders dividends from its net investment income and distributes any net realized capital gains once each year. Your distributions will be reinvested in the Fund unless you instruct the Fund otherwise. There are no charges on reinvestments. After every distribution, the value of a share is automatically reduced by the amount of the distribution. If you elect not to reinvest and the postal or other delivery service is unable to deliver checks to your address of record, your distribution will be reinvested in additional shares at the next NAV calculated after the check is returned to the Fund. No interest will accrue on amounts represented by uncashed distribution or redemption checks.

Potential investors should read the “U.S. Federal Income Taxation” section on pages 83‑85 of this Prospectus and the “Taxation of the Funds” section on pages 40-46 in the SAI for information on the tax treatment of distributions from the Funds and for a discussion of the tax consequences of an investment in the Funds. References below to the “Fund” apply to each of the Funds described in this Prospectus.

Policies Regarding Frequent Purchases and Redemptions of Fund Shares

The Funds discourage any person who is not a long-term investor from investing in the Funds. The Funds make investments for the long term and have had relatively low turnover of the portfolios (please see the “Additional Investment Strategies” section on pages 56-59 of this Prospectus and the “Principal Investment Strategies of the Fund” sections of each summary section beginning on page 4 of the Prospectus). The Board has adopted policies and procedures to minimize frequent purchases and

1-800-99BARON 79

Information about your Investment Baron Funds^®

redemptions of Fund shares by shareholders. The Board believes that frequent trading (which may include market timing, short-term trading or excessive trading) of Fund shares has the potential to adversely impact other shareholders of the Funds.

The Board believes that frequent trading of Fund shares causes risks to the Funds and their shareholders. Frequent trading may dilute the value of Fund shares held by long-term shareholders, trigger gains taxable to Fund shareholders, increase brokerage and administrative costs and interfere with the efficient management of the Funds. It may disrupt the Adviser’s ability to manage the Funds in accordance with their goals. This disadvantages other shareholders of the Funds and adds to Fund costs, since the Adviser may be required to sell investments prematurely to raise cash to meet redemptions. The impact could be particularly severe for a smaller Fund because the frequent activity would have a greater impact on each remaining long-term shareholder. Shareholders could also be negatively affected by frequent trading if the Adviser is forced to rebalance the portfolio and thereby incur substantial expenses in doing so.

Trades in and out of a Fund within 90 days or less may be indicative of frequent trading.  If the Adviser believes that an investor is a frequent trader, the Adviser, in its sole discretion, may temporarily or permanently bar that investor from trading in the Fund or any Baron Funds^®. Exchanges between the Funds within 90 days or less will generally not be considered frequent trading, unless the Adviser, in its sole discretion, determines that such exchanges are excessive. Although the Adviser uses a variety of methods to detect and deter frequent trading, there is no assurance that the Adviser’s own operational systems and procedures will identify and eliminate all frequent trading strategies. For example, certain accounts, which are known as omnibus accounts, include multiple investors and such accounts typically provide the Funds with a net purchase or redemption order on any given day where purchasers of Fund shares and redeemers of Fund shares are netted against one another and the identity of individual purchasers and redeemers are not known by the Funds.

If the Funds reasonably believe that certain financial intermediaries are not enforcing the Funds’ policies regarding frequent purchases and redemptions of Fund shares, the Funds may prohibit the financial intermediary from investing in the Funds on behalf of any of its clients. However, certain financial intermediaries and administrators may not have systems that can accommodate the Funds’ policies regarding the frequent purchases and redemptions of Fund shares. In these limited instances, the Funds must rely on those financial intermediaries and administrators to enforce their own frequent trading policies. If the Adviser reasonably believes that a financial intermediary is not enforcing its own policy, or the Funds’ policies regarding frequent purchases and redemptions of Fund shares, even though it has the appropriate systems, the Funds may prohibit the financial intermediary from investing in the Funds on behalf of any of its clients.

Information about your Investment Baron Funds^®

The Funds’ policies and procedures may be modified or terminated at any time. The Funds reserve the right to reject any purchase or exchange request for any reason. The Adviser, in its sole discretion, may waive its policies regarding frequent purchases and redemptions of Fund shares for purchases, redemptions and exchanges that are part of a rebalancing or asset allocation program administered by an approved financial intermediary.

How to Exchange Shares

You may exchange all or a portion of your investment from one Baron Fund into another. You may exchange shares by mail, telephone (speaking with a representative or using our automated voice recognition system “BaronTel”) or through the Baron Funds^® website. You must not have opted out of the telephone option to do an exchange via telephone or online (please see the “Special Information about the Baron Funds^® Website” section on pages 82-83 of this Prospectus). Any new account established through an exchange will have the same registration, the same privileges and will be subject to the same minimum investment requirements as your original account. There is currently no fee for an exchange. Exchanges will be executed on the basis of the relative NAV of the shares exchanged. An exchange is considered a sale for U.S. federal income tax purposes, and you may therefore realize a gain or loss for U.S. federal income tax purposes as a result of an exchange. The policy of the Funds is to presume that a person who trades in and out of a Fund within 90 days or less is not a long-term investor (please see the “Policies Regarding Frequent Purchases and Redemptions of Fund Shares” section on pages 79-81 of this Prospectus). Exchanges between the Funds within 90 days or less will generally not be considered frequent trading unless the Adviser, in its sole discretion, determines that such exchanges are excessive. The Funds reserve the right to cancel the exchange privilege of any investor who uses the exchange privilege excessively. The Funds may change or temporarily suspend the exchange privilege during unusual market conditions.

How to Convert Shares

The Funds offer three classes of shares, Retail Shares, Institutional Shares and R6 Shares, which differ only in their ongoing fees and eligibility requirements. You may convert Retail Shares into Institutional Shares if the value of your investment in a Fund is at least $1,000,000. If the value of your investment in a Fund falls below $1,000,000, the Fund may convert your Institutional Shares into Retail Shares. You may convert Retail Shares or Institutional Shares into R6 Shares if you meet the eligibility requirements. The transaction will be based on the respective NAV of each class to be exchanged on the trade date for the conversion. For U.S. federal income tax purposes, such a conversion is not a taxable event. You should consult your own tax adviser regarding specific questions of federal, state, local or foreign tax law.

U.S. Federal Income Taxation

Tax Status of the Fund

Each Fund intends to qualify every year as a “regulated investment company” under the Code. If a Fund qualifies as a regulated investment company, it generally will not be subject to U.S. federal income tax on income that is distributed to shareholders, provided that it distributes to its shareholders at least 90% of its “investment company taxable income” (which includes, among other items, dividends, interest, the excess of net short-term capital gains over net long-term capital losses and other taxable income other than the excess of net long-term capital gains over net short-term capital losses) and 90% of its net tax-exempt interest income in each year.

Taxability of Dividends and Distributions

The Funds intend to pay dividends from their net investment income and to distribute any net realized capital gains once each year. Distributions of a Fund’s investment company taxable income (other than “qualified dividend income”), including distributions of net short-term capital gains, will be taxable to you as ordinary income. Distributions of a Fund’s net capital gains (the excess of a Fund’s net long-term capital gain for the taxable year over its net short-term capital loss for that year) reported as capital gain dividends by a Fund will be taxable to you as long-term capital gains, regardless of the length of time you have held shares of a Fund. Distributions in excess of a Fund’s current and accumulated earnings and profits will be treated as a tax-free return of capital, to the extent of your adjusted basis in your shares of a Fund, and as a capital gain thereafter (if you held your shares of the relevant Fund as capital assets). Provided that you satisfy the applicable holding period and other requirements with respect to your shares of a Fund, distributions of a Fund’s “qualified dividend income” will be treated as “qualified dividend income” received by you and, if you are an individual or other non-corporate shareholder, will therefore be subject to U.S. federal income tax at the rates applicable to long-term

1-800-99BARON 83

Information about your Investment Baron Funds^®

capital gains. Your tax liabilities for such distributions will depend on your particular tax situation.

Your distributions will be reinvested in the Fund unless you instruct the Fund otherwise. If you do not instruct the Fund not to reinvest distributions in additional shares of a Fund, you will be treated for U.S. federal income tax purposes as receiving the relevant distributions and using them to purchase shares. All distributions of investment company taxable income and net capital gains, whether received in cash or reinvested, must be reported on your U.S. federal income tax return.

Annual year-end distribution estimates, if any, are expected to be available beginning in November or December of each year, and may be updated from time to time, on the Baron Funds^® website at www.BaronFunds.com. A distribution will be treated as paid during a calendar year if it is declared by the Fund in October, November or December of the year to holders of record in such a month and paid by January 31 of the following year. Distributions paid in January will be taxable to you as if received on December 31 of such prior year, rather than in the year in which the distributions are actually received.

Dividends and interest received by a Fund may give rise to withholding and other taxes imposed by foreign countries. If a Fund meets certain requirements and so elects, a ratable portion of the amounts withheld or paid will generally be taxable to you as a shareholder even though you do not receive them. In that case, you will generally be able to claim a tax credit or a deduction for your portion of any foreign withholding and income taxes paid by a Fund, subject to generally applicable limitations.

A Fund must withhold 28% of your dividends and redemption proceeds if you have not provided a taxpayer identification number or social security number or if the number you have provided is incorrect.

Taxability of the Sale or Redemption of Shares

You will recognize a taxable gain or loss, if any, if you sell or redeem your shares. You will generally be subject to taxation based on the difference between your adjusted tax basis in your shares that are sold or redeemed and the value of the cash or other property you receive in payment therefor.

Any gain or loss arising from the sale or redemption of shares will be treated as capital gain or loss if the shares are capital assets in your hands and will generally be long-term capital gain or loss if your holding period for your shares is more than one year and short-term capital gain or loss if it is one year or less. Currently, long-term capital gains recognized by individuals and other non-corporate shareholders on a sale or redemption of shares generally are taxed at a maximum rate of 20%. Any loss realized on a sale or redemption will be disallowed to the extent the shares you dispose of are replaced

84 www.BaronFunds.com

Information about your Investment Baron Funds^®

(including pursuant to our dividend reinvestment program) with substantially identical shares within a period beginning 30 days before and ending 30 days after the disposition of your shares. In such a case, your basis in the shares acquired will be adjusted to reflect the disallowed loss. Any loss arising from the sale or redemption of shares for which you have a holding period of six months or less will be treated for U.S. federal tax purposes as a long-term capital loss to the extent of any amount of capital gain dividends you received with respect to such shares.

Cost Basis Information

A Fund is required to report your cost basis, gain or loss, and holding period to the Internal Revenue Service on your Consolidated Form 1099 when “covered” shares of the Fund are redeemed. Covered shares are any shares acquired (including shares acquired through reinvestment of the Fund’s distributions) on or after January 1, 2012. Each of the Funds has chosen the “average cost” method as its default method for reporting the cost basis of covered shares. Each Fund will use this method for purposes of reporting your cost basis unless you instruct the relevant Fund in writing to use a different calculation method. You may choose a method different from the Funds’ default method if you provide the Fund with timely notice. Please consult your tax advisor with regard to your particular circumstances.

The foregoing is a summary of some of the important U.S. federal income tax considerations affecting the Funds and their shareholders. It is not a complete analysis of all relevant tax considerations, nor is it a complete listing of all potential tax risks involved in purchasing or holding shares of the Funds. You should consult your own tax adviser regarding specific questions of federal, state, local or foreign tax law.

Distribution and Servicing Arrangements

12b-1 Plan

The Funds have adopted a distribution and servicing plan for Retail Shares (the “12b‑1 Plan”) under Rule 12b-1 of the Investment Company Act of 1940 that allows the Funds to pay fees for the distribution of Retail Shares and for shareholder services provided to holders of Retail Shares. A substantial portion of the 12b-1 fees is directed to third parties that provide shareholder servicing to existing shareholders. The 12b-1 Plan authorizes the Funds to pay BCI a distribution fee equal to 0.25% per annum of each Fund’s average daily net assets attributable to the Retail Shares (please see the “12b-1 Plan” section in the SAI). Due to the possible continuing nature of Rule 12b-1 payments, long-term investors in Retail Shares may pay more than the economic equivalent of the maximum front-end sales charge permitted by

1-800-99BARON 85

Information about your Investment Baron Funds^®

FINRA. The 12b-1 Plan does not apply to Institutional Shares or R6 Shares.

Third Party Arrangements.  In addition to payments under the 12b-1 Plan, the Adviser, the Distributor or their affiliates may, at their own expense out of their own financial resources, make payments to some, but not all brokers, dealers or other financial intermediaries, including retirement plan sponsors, service providers and administrators providing recordkeeping, administrative and/or other services to plan participants (collectively, “financial intermediaries”), as additional compensation for services and/or as an incentive to sell both Retail and Institutional Shares of the Funds and/or promote retention of their customers’ assets in the Funds. These payments, some of which may be referred to as “revenue sharing” payments, do not change the price paid by investors to purchase the Funds’ shares or the amount the Funds receive as proceeds from such sales.

Payments may be made to financial intermediaries that provide services to the Funds or to shareholders of the Funds, including shareholder servicing, transaction processing, sub-transfer agency services, sub-accounting services, marketing support, conference support and/or access to sales meetings, sales representatives and management representatives of the financial intermediary. Payments may also be made to financial intermediaries for inclusion of the Funds on a sales list, including a preferred or select sales list, in other sales programs and platforms, or as an expense reimbursement in cases where the financial intermediary provides shareholder services to Fund shareholders. Payments may be structured: (i) as a percentage of net sales; (ii) as a percentage of net customer assets; (iii) as a fixed dollar amount; and/or (iv) on a per account basis. The amount of payments made to a financial intermediary in any given year may vary based on the amount of Fund assets attributable to that financial intermediary.

The Funds may pay fees to financial intermediaries out of the applicable Fund’s assets (in addition to 12b-1 fees for Retail Shares) for servicing shareholder accounts. Such financial intermediaries typically would have omnibus accounts with the Transfer Agent and provide shareholder servicing and/or sub-transfer agent or sub-accounting services to shareholders or beneficial owners. It is anticipated that any amounts paid by a Fund to such financial intermediaries generally would not exceed the estimated amount the Fund would have incurred in maintaining and servicing the shareholder accounts in the Fund directly rather than through these financial intermediaries. As of September 30, 2021, the Funds have made no such payments.

Financial Highlights

The financial highlights table is intended to help you understand the Funds’ financial performance for the fiscal years indicated. Certain information reflects financial results for a single Fund share. The “total return” shows how much your investment in a Fund would have increased (or decreased) during each period, assuming you had reinvested all dividends and distributions. These financial highlights, for each of the fiscal years presented in the five year period ended September 30, 2021 or the fiscal years of a Fund’s operations, if less than five years, have been audited by PricewaterhouseCoopers LLP, the Funds’ independent registered public accounting firm, whose report, along with the Funds’ financial statements, is included in the Funds’ Annual Financial Report, which is available upon request by calling 1-800-99BARON or by emailing info@baronfunds.com. The Annual Financial Report is also incorporated by reference in the SAI. The SAI and the Financial Reports can be found at www.BaronFunds.com.

FUND HISTORY

Effective October 22, 2004, the name of Baron Asset Fund was changed to Baron Investment Funds Trust (the “Trust”). The Trust is an open-end, diversified management investment company originally organized and established under the laws of the Commonwealth of Massachusetts on February 19, 1987. The Trust is structured to be able to issue shares in multiple series, each constituting a separate portfolio with separate assets and liabilities from any other series. There are seven series currently available (individually, a “Fund,” and collectively, the “Funds”):

Name of Series	Date of First Public Offering	Date of Commencement of Investment Trading
Baron Asset Fund	June 11, 1987	June 12, 1987
Baron Growth Fund	December 31, 1994	January 3, 1995
Baron Small Cap Fund	September 30, 1997	October 1, 1997

DESCRIPTION OF THE FUNDS AND THEIR INVESTMENTS AND RISKS

Investment Strategies and Risks.

• Baron Asset Fund’s investment goal is to seek capital appreciation through long-term investments primarily in securities of mid-sized growth companies with undervalued assets or favorable growth prospects. Baron Asset Fund invests 65% of its net assets in equity securities in the form of common stock of mid-sized growth companies with market capitalizations above $2.5 billion or the smallest market cap stock in the Russell Midcap Growth Index at reconstitution, whichever is larger, and below the largest market cap stock in the Russell Midcap Growth Index at reconstitution. The 65% standard is measured at the time of purchase.

• Baron Growth Fund’s investment goal is to seek capital appreciation through long-term investments primarily in securities of small-sized growth companies. Baron Growth Fund invests 65% of its net assets in equity securities in the form of common stock of small-sized growth companies with market capitalizations up to the largest market cap stock in the Russell 2000 Growth Index at reconstitution, or companies with market capitalizations up to $2.5 billion, whichever is larger. The 65% standard is measured at the time of purchase.

• Baron Small Cap Fund’s investment goal is to seek capital appreciation through investments primarily in securities of small-sized growth companies. Baron Small Cap Fund invests 80% of its net assets in equity securities in the form of common stock of small-sized growth companies with market capitalizations up to the largest market cap stock in the Russell 2000 Growth Index at reconstitution, or companies with market capitalizations up to $2.5 billion, whichever is larger. The 80% standard is measured at the time of purchase.

• The investment goal of Baron Opportunity Fund is capital appreciation through investments primarily in growth companies that benefit from technology advances. Baron Opportunity Fund invests primarily in equity securities in the form of common stock of high growth businesses of any market capitalization selected for their capital appreciation potential.

• Baron Fifth Avenue Growth Fund’s investment goal is to seek capital appreciation through investments primarily in securities of large-sized growth companies. Baron Fifth Avenue Growth Fund invests 65% of its net assets in equity securities in the form of common stock of large-sized growth companies with market capitalizations no smaller than the top 85^th percentile by total market capitalization of the Russell 1000 Growth Index at June 30, or companies with market capitalizations above $10 billion, whichever is smaller. The 65% standard is measured at the time of purchase.

3

• Baron Discovery Fund’s investment goal is to seek capital appreciation through investments primarily in securities of small-sized growth companies. Baron Discovery Fund invests 65% of its net assets in equity securities in the form of common stock of small-sized growth companies with market capitalizations up to the largest market cap stock in the Russell 2000 Growth Index at reconstitution, or companies with market capitalizations up to $2.5 billion, whichever is larger. The 65% standard is measured at the time of purchase.

• Baron Durable Advantage Fund’s investment goal is to seek capital appreciation through investments primarily in securities of large-sized companies. Baron Durable Advantage Fund invests primarily in equity securities in the form of common stock of large-sized companies. The Adviser defines large-sized companies as those, at the time of purchase, with market capitalizations no smaller than the top 90^th percentile by total market capitalization of the S&P 500 Index at June 30, or companies with market capitalizations above $10 billion, whichever is smaller.

Because Baron Asset Fund, Baron Growth Fund, Baron Small Cap Fund, Baron Opportunity Fund, Baron Discovery Fund and Baron Durable Advantage Fund invest for the long term, they may hold securities that have appreciated beyond their market capitalizations at the time of the Funds’ investments.

In addition to the investment strategies of the Funds described in each of their respective summary sections and in the Prospectus on pages 56-59, the Funds may use the additional strategies described below. These investment strategies are not fundamental policies and may be changed by the Trust’s Board of Trustees (the “Board”) without shareholder approval upon at least 60 days’ notice. Shareholders will be notified of any material changes. Some of the strategies discussed below are mentioned in the prospectus, but they are explained in more detail here.

Recent Market and Economic Developments

A outbreak of respiratory disease caused by a novel coronavirus was first detected in Wuhan City, Hubei Province, China and has spread internationally. The virus, named “SARS-CoV-2” (sometimes referred to as the “coronavirus”) and the resulting disease, which is referred to as “COVID-19,” has been declared a pandemic by the World Health Organization and has resulted in border closings, enhanced health screenings, healthcare service preparation and delivery, quarantines, cancellations, disruptions to supply chains and customer activity, as well as general concern and uncertainty.

The United States and many other developed and emerging market countries and global debt and equity capital markets have been materially and adversely affected by the impact of, and the significant uncertainty about the future caused by, the pandemic spread of COVID-19. As a result, certain financial institutions as well as the global financial system experienced severe economic distress. There have been material and adverse impacts on the broader financial and credit markets and the debt and equity capital for the market as a whole, and certain risks discussed in the Prospectus and elsewhere in this SAI may be exacerbated, such as credit risk, liquidity risk, interest rate risk and the risks of investing in certain sectors. Many interest rates are very low and in some cases yields are negative, and it is possible that, particularly during periods of low prevailing interest rates, the income from Fund securities will be reduced. These events have contributed, and may continue to contribute, to severe market volatility, which may adversely impact the Funds’ net asset values and result in heightened volatility in the performance of the Funds’ investments. In addition to these events having adverse consequences for the Funds and the Funds’ investments, the operations of the Adviser and its affiliates and the Funds’ other service providers have been impacted, and may continue to be impacted, perhaps significantly adversely impacted, as a result of the COVID-19 pandemic, such as restrictions on certain business operations, which may have long-term negative impacts on such operations generally or the ability of such operations to remain viable; more limited resources as the result of adverse market conditions that may negatively impact the cash flow and/or profitability of such businesses; quarantine measures and travel restrictions imposed on such entities’ personnel based or temporarily located in affected regions; or any related health issues of such entities’ personnel.

4

Some sectors of the economy and individual issuers experienced particularly large losses. Many of them have recovered somewhat. For example, companies in the energy sector, including MLPs and energy infrastructure companies in which certain Funds invest, for a period were adversely impacted by reduced demand for oil and other energy commodities as a result of the slowdown in economic activity resulting from the pandemic spread of COVID-19 and by price competition among key oil producing countries.

The United States has responded to the COVID-19 pandemic and resulting economic distress with fiscal and monetary stimulus packages. In late March 2020, Congress passed, and President Trump signed, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”), a stimulus package providing for over $2.2 trillion in resources to small businesses, state and local governments, and individuals that have been adversely impacted by the COVID-19 pandemic. During the Biden Administration, additional legislation in response to COVID-19 has been passed. The Federal Reserve also enacted various programs to support liquidity operations and funding in the financial markets, including massively expanding its reverse repurchase agreement operations, adding $1.5 trillion of liquidity to the banking system; establishing swap lines with other major central banks to provide dollar funding; establishing a program to support money market funds; easing various bank capital buffers; providing funding backstop for businesses to provide bridging loans for up to four years; and providing funding to help credit flow in asset-backed securities markets. Recently, the threat of inflation has caused the Federal Reserve to reconsider or reverse some of these actions and policies.

The current market conditions, as well as various social and political tensions in the United States and around the world, may continue to contribute to increased market volatility, may have long-term effects on the U.S. and global financial markets, and may cause further economic uncertainties or deterioration in the United States and worldwide. The prolonged continuation or further deterioration of the current U.S. and global economic downturn could adversely impact the Funds. The Adviser does not know how long the financial markets will continue to be affected by these events and cannot predict the effects of these or similar events in the future on the US economy, the securities markets and issuers held by a Fund. Fiscal stimulus packages such as the CARES Act serve to further increase the federal budget deficit, which could lead to the downgrading of the long-term sovereign credit rating for the United States. Federal Reserve policy in response to market conditions, including with respect to certain interest rates, may adversely affect the value, volatility and liquidity of dividend and interest paying securities. Market volatility, dramatic changes to interest rates and/or a return to unfavorable economic conditions may lower a Fund’s performance or impair a Fund’s ability to achieve its investment objective. The Adviser intends to monitor developments and seek to manage the Funds in a manner consistent with achieving each Fund’s investment objective, but there can be no assurance that it will be successful in doing so.

Non-U.S. Securities.

The Funds may invest without limitation in the securities of non-U.S. issuers in U.S. denominated form known as American Depository Receipts (“ADRs”). They may also invest up to 10% of the respective total assets of Baron Asset Fund, Baron Growth Fund and Baron Small Cap Fund, and up to 25% of the respective total assets of Baron Opportunity Fund, Baron Fifth Avenue Growth Fund, Baron Discovery Fund and Baron Durable Advantage Fund directly in the securities of non-U.S. issuers that are not publicly traded in the U.S. and in Global Depository Receipts (“GDRs”) and European Depository Receipts (“EDRs”).

ADRs are certificates issued by a U.S. bank or trust company and represent the right to receive securities of a foreign issuer deposited in a U.S. bank or foreign branch of a U.S. bank and traded on a U.S. exchange or in an over-the-counter market. EDRs and GDRs are receipts issued in Europe generally by a non-U.S. bank or trust company that evidence ownership of non-U.S. securities. There are no fees imposed on the purchase or sale of ADRs, EDRs or GDRs, although the issuing bank or trust company may impose fees on the purchase of dividends and the conversion of ADRs, EDRs and GDRs into the underlying securities. Investments in ADRs have certain advantages over direct investment in the underlying non-U.S. securities, since (i) ADRs are U.S. dollar denominated investments that are easily transferable and for which market quotations are readily available

5

and (ii) issuers whose securities are represented by ADRs are subject to the same auditing, accounting and financial reporting standards as U.S. issuers. EDRs and GDRs are not necessarily denominated in the currency of the underlying security. Issuers of non-U.S. securities are subject to different, often less detailed, accounting, reporting and disclosure requirements than are U.S. issuers. These securities may have exposure to developed countries and developing countries, which 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.

REITs.

The Funds may invest in the equity securities of real estate investment trusts (“REITs”). A REIT is a corporation or business trust that invests in real estate and derives its income from rents or sales of real property or interest on loans secured by mortgages on real property. The market value of REITs may be affected by numerous factors, including decreases in the value of real estate, vacancies, decreases in lease rates, defaults by lessees, changes in the tax laws or by their inability to qualify for the tax-free pass-through of their income.

Securities Lending.

The Funds may lend their portfolio securities to qualified institutions. By lending its portfolio securities, a Fund attempts to increase its income through the receipt of interest on the loan. Any gain or loss in the market price of the securities loaned that may occur during the term of the loan will be for the account of the Fund. A Fund may lend its portfolio securities so long as the terms and the structure of such loans are not inconsistent with the requirements of the Investment Company Act of 1940, as amended (the “1940 Act”), which currently provide that (a) the borrower pledges and maintains with the Fund collateral consisting of cash, a letter of credit issued by a domestic U.S. bank, or securities issued or guaranteed by the U.S. government having a value at all times not less than 100% of the value of the securities loaned, (b) the borrower adds to such collateral whenever the price of the securities loaned rises (i.e., the value of the loan is “marked to the market” on a daily basis), (c) the loan be made subject to termination by the Fund at any time and the loaned securities be subject to recall within the normal and customary settlement time for securities transactions and (d) the Fund receives reasonable interest on the loan (which may include the Fund’s investing any cash collateral in interest bearing short-term investments), any distributions on the loaned securities and any increase in their market value. If the borrower fails to maintain the requisite amount of collateral, the loan automatically terminates and the Fund could use the collateral to replace the securities while holding the borrower liable for any excess of replacement cost over the value of the collateral. As with any extension of credit, there are risks of delay in recovery and in some cases even loss of rights in collateral should the borrower of the securities fail financially.

A Fund will not lend portfolio securities if, as a result, the aggregate of such loans for Baron Asset Fund exceeds 10% and for Baron Growth Fund, Baron Small Cap Fund, Baron Opportunity Fund, Baron Fifth Avenue Growth Fund, Baron Discovery Fund and Baron Durable Advantage Fund exceeds 25% of the value of its total assets (including such loans). Loan arrangements made by a Fund will comply with all other applicable regulatory requirements. All relevant facts and circumstances, including the creditworthiness of the qualified institution, will be monitored by the Adviser, and will be considered in making decisions with respect to lending of securities, subject to review by the Trust’s Board of Trustees.

A Fund may pay reasonable negotiated fees in connection with loaned securities, so long as such fees are set forth in a written contract and approved by its Board of Trustees. In addition, a Fund shall, through the ability to recall securities prior to any required vote, retain voting rights over the loaned securities.

When-Issued and Delayed-Delivery Securities and Forward Commitments.

The Funds may purchase or sell securities on a when-issued or delayed-delivery basis. When-issued or delayed-delivery transactions arise when securities are purchased or sold with payment and delivery taking place

6

in the future in order to secure what is considered to be an advantageous price at the time of entering into the transaction. While a Fund generally purchases securities on a when-issued basis with the intention of acquiring the securities, the Fund may sell the securities before the settlement date if the Adviser deems it advisable. Distributions attributable to any gains realized on such a sale are taxable to shareholders. When-issued and delayed-delivery securities and forward commitments involve the risk that the security a Fund buys will lose value prior to its delivery. There are also the risks that the security will never be issued or that the other party to the transaction will not meet its obligation. If this occurs, a Fund loses both the investment opportunity for the assets it set aside to pay for the security and any gain in the security’s price. The Funds do not anticipate investing more than 10% of their total assets in such securities.

Illiquid Securities.

Baron Asset Fund may invest up to 10% of its net assets, and Baron Growth Fund, Baron Small Cap Fund, Baron Opportunity Fund, Baron Fifth Avenue Growth Fund, Baron Discovery Fund and Baron Durable Advantage Fund may invest up to 15%, of their respective net assets in illiquid securities at the time of purchase. Subsequently, if as a result of changes in the portfolio, illiquid securities exceed 10 or 15% of net assets (as applicable), a Fund may not acquire any additional illiquid securities and the Adviser will take such steps as it considers appropriate to reduce the percentage within a reasonable period of time. An illiquid security is one that a Fund reasonably expects to be unable to sell or dispose of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the security. Such investments may include private equity securities, private investments in public equity securities and other restricted securities. To the extent that there is no established market for some of the debt securities in which the Funds may invest, there may be thin or no trading in such securities, and the ability of the Adviser to value accurately such securities may be adversely affected. Further, it may be more difficult for the Funds to sell securities for which no established market exists. During periods of reduced market liquidity, and in the absence of readily available market quotations for securities held in the Funds’ portfolios, the responsibility of the Adviser to value the Funds’ securities becomes more difficult, and the Adviser’s judgment may play a greater role in the valuation of the Funds’ securities due to a reduced availability of reliable data.

To the extent that the Funds purchase illiquid securities or securities that are restricted as to resale, the Funds may incur additional risks and costs. Illiquid and restricted securities may be particularly difficult to value and their disposition may require greater effort and expense than more liquid securities. The Funds may be required to incur costs in connection with the registration of restricted securities in order to dispose of such securities.

If one or more instruments in a Fund’s portfolio become illiquid, the Fund may exceed its limit on illiquid instruments. If this occurs, the Fund must take steps to bring the aggregate amount of illiquid instruments back within the prescribed limitations as soon as reasonably practicable. However, this requirement will not force a Fund to liquidate any portfolio instrument where the Fund would suffer a loss on the sale of that instrument.

Debt Securities.

Debt securities have varying levels of sensitivity to changes in interest rates. In general, the price of a debt security can fall when interest rates rise and can rise when interest rates fall. Securities with longer maturities can be more sensitive to interest rate changes. The longer the maturity of a security, the greater the impact a change in interest rates could have on the security’s price. In addition, short-term and long-term interest rates do not necessarily move in the same amount or the same direction. Short-term securities tend to react to changes in short-term interest rates, and long-term securities tend to react to changes in long-term interest rates.

Debt securities, particularly mortgage-backed securities, are subject to prepayment risk. Prepayment risk occurs when the issuer of a security can repay principal prior to the security’s maturity. Securities subject to prepayment can offer less potential for gains during a declining interest rate environment and similar or greater potential for loss in a rising interest rate environment. In addition, the potential impact of prepayment features on

7

the price of a debt security can be difficult to predict and result in greater volatility. The Funds do not anticipate investing more than 5% of their respective assets in mortgage-backed securities.

The Funds may invest in zero-coupon, step-coupon and pay-in-kind securities. These securities are debt securities that do not make regular interest payments. Zero-coupon and step-coupon securities are sold at a deep discount to their face value, and pay-in-kind securities pay interest through the issuance of additional securities.

The market value of these debt securities generally fluctuates in response to changes in interest rates to a greater degree than interest-paying securities of a comparable term and quality. The secondary market value of corporate debt securities structured as zero-coupon securities or pay-in-kind securities may be more volatile in response to changes in interest rates than debt securities that pay interest periodically in cash. Because such securities do not pay current interest but instead accrue such income, to the extent that the Funds do not have available cash to meet distribution requirements with respect to such income, they could be required to dispose of portfolio securities that they would not otherwise. Such disposition could be at a disadvantageous price. Investments in such securities also involve certain tax considerations.

The Funds from time to time may also purchase indebtedness and participations, both secured and unsecured, of debtor companies in reorganization or financial restructuring. Such indebtedness may be in the form of loans, notes, bonds or debentures. When the Funds purchase a participation interest they assume the credit risk associated with the bank or other financial intermediary as well as the credit risk associated with the issuer of any underlying debt instrument. The Funds may also purchase trade and other claims against, and other unsecured obligations of, such debtor companies, which generally represent money due a supplier of goods or services to such company. Some debt securities purchased by the Funds may have very long maturities. The length of time remaining until maturity is one factor that the Adviser considers in purchasing a particular debt security. The purchase of indebtedness of a troubled company always involves a risk as to the creditworthiness of the issuer and the possibility that the investment may be lost. The Adviser believes that the difference between perceived risk and actual risk creates the opportunity for profit, which can be realized through thorough analysis. There are no established markets for some of this indebtedness, and it is less liquid than more heavily traded securities. Indebtedness of the debtor company to a bank is not the security of the banks issuing or selling them. The Funds may purchase loans from national and state chartered banks as well as foreign ones. The Funds may invest in senior indebtedness of debtor companies, although on occasion subordinated indebtedness may also be acquired. The Funds may also invest in distressed first mortgage obligations and other debt secured by real property. The Funds do not currently anticipate investing more than 10% of their total assets in trade and other claims.

Repurchase and Reverse Repurchase Agreements.

The Funds may enter into repurchase agreements with certain banks or non-bank dealers. In a repurchase agreement, the Funds buy a security at one price, and at the time of sale, the seller agrees to repurchase that security at a mutually agreed upon time and price. Repurchase agreements could involve certain risks in the event of the failure of the seller to repurchase the securities as agreed, which may cause the Funds to suffer a loss, including loss of interest on, or principal of, the security and costs associated with delay and enforcement of the repurchase agreement. Repurchase agreements with a duration of more than seven days are considered illiquid securities. Repurchase agreements carry the risk that the market value of the securities declines below the repurchase price. Also a Fund could lose money if it is unable to recover the securities and the value of the collateral held by the Fund is less than the value of the securities. In the event the borrower commences bankruptcy proceedings, a court may characterize the transaction as a loan. If a Fund has not perfected a security interest in the underlying collateral, the Fund may be required to return the underlying collateral to the borrower’s estate and be treated as an unsecured creditor. As an unsecured creditor, the Fund could lose some or all of the principal and interest involved in the transaction.

The Funds may engage in reverse repurchase agreements with certain banks or non-bank dealers, where the Funds sell a security and simultaneously agree to buy it back at a mutually agreed upon time and price. To the

8

extent that the Funds engage in reverse repurchase agreements, they will maintain a segregated account consisting of liquid assets or highly marketable securities to cover their obligations. Reverse repurchase agreements are a type of borrowing that may increase the possibility of fluctuation in a Fund’s net asset value.

The SEC recently adopted new Rule 18f-4 under the 1940 Act, which governs the use of derivative investments and certain financing transactions (e.g. reverse repurchase agreements) by registered investment companies. As the Fund comes into compliance, the approach to asset segregation and coverage requirements described in this SAI will be impacted. For more information, please see the “Use of Derivatives, Segregated Accounts and Other Special Accounts” section on page 12.

Medium And Lower-Rated Corporate Debt Securities.

The Funds may invest in debt securities that have a rating of, or equivalent to, at least “BBB” by Standard & Poor’s Corporation (“S&P”) or “Baa” by Moody’s Investors Services, Inc. (“Moody’s”), or if unrated, are judged by the Adviser to be of comparable quality. Baron Asset Fund, Baron Growth Fund, Baron Opportunity Fund, Baron Fifth Avenue Growth Fund, Baron Discovery Fund and Baron Durable Advantage Fund may invest up to 35% of their total assets in such securities. Baron Small Cap Fund may invest up to 20% of its total assets in such securities. Because the creditworthiness of an issuer may change more rapidly than is able to be timely reflected in changes in credit ratings, the Adviser monitors corporate debt securities of issuers held in the Funds’ equity portfolios. The Adviser could be wrong in its analysis. A general economic downturn or a significant increase in interest rates could severely disrupt the market for medium and lower grade corporate debt securities and adversely affect the market value of such securities and lead to increased incidences of default. Yields on debt securities in the portfolio that are interest rate sensitive can be expected to fluctuate over time.

Short Sales.

Baron Growth Fund, Baron Small Cap Fund, Baron Opportunity Fund, Baron Fifth Avenue Growth Fund, Baron Discovery Fund and Baron Durable Advantage Fund may sell securities short. The Funds may sell a security that the Funds do not own. In order to do so, the Funds must borrow a security to deliver it to the purchaser and later buy that security in the market and return it to the lender. The value of a security sold short could increase and the Funds would have to pay more to buy the security to return to the lender than it received from the purchaser in the short sale. The Funds’ risk of loss in these types of short sales is theoretically unlimited because there is no limit to the cost of replacing the borrowed security. The Funds may also sell a security short that the Funds own or a security equivalent in kind or amount to a security the Funds have a right to obtain (for example, a security convertible into the security sold short or a security that the Adviser believes will be deliverable upon the closing of a transaction). The Funds may also sell securities short when, in the opinion of the Adviser, the position is covered by owning a security that has ownership rights to assets that include all of the assets of the security shorted. If the value of the securities in these types of short sales increases, the Funds lose the opportunity to participate in the gain of the covered positions. The Funds may sell a security short only on a fully collateralized basis, which requires that the Funds establish and maintain a segregated account.

Options Transactions and Swaps.

Baron Asset Fund may write (sell) covered call options or purchase put options on equity and/or debt securities. Baron Growth Fund, Baron Small Cap Fund, Baron Opportunity Fund, Baron Fifth Avenue Growth Fund, Baron Discovery Fund and Baron Durable Advantage Fund may write (sell) put and covered call options and purchase put and call options on equity and/or debt securities. The Funds may also enter into equity swap transactions. All calls sold by the Funds must be “covered” (i.e., a Fund must own the underlying securities) or must meet the asset segregation requirements described below for as long as the call is outstanding. Even though the Funds will receive the option premium to help protect it against loss, a call sold by a Fund exposes the Funds during the term of the option to possible loss of opportunity to realize appreciation in the market price of the underlying security or instrument and may require the Fund to hold a security or instrument which it might otherwise have sold, and a put sold by a Fund exposes the Fund to potential loss in the amount of the difference between the exercise price and the market value of the underlying security.

9

A put option gives the purchaser of the option, upon payment of a premium, the right to sell, and the writer, when exercised, the obligation to buy, the underlying security at the exercise price. A call option, upon payment of a premium, gives the purchaser of the option the right to buy, and the seller, if exercised, the obligation to sell, the underlying security at the exercise price. An American style put or call option may be exercised at any time during a fixed period, while a European style put or call option may be exercised only upon expiration or during a fixed period prior thereto. The Funds may engage in either style option. The Funds are authorized to engage in transactions with respect to exchange-listed options, over-the-counter options (“OTC options”) and other derivative investments. Exchange-listed options are issued by a regulated financial intermediary, such as the Options Clearing Corporation (“OCC”), which guarantees the performance of the obligations of the parties to such options. The discussion below uses the OCC as an example, but is also applicable to other financial intermediaries.

Rather than taking or making delivery of the underlying security through the process of exercising the option, listed options are usually closed by entering into offsetting purchase or sale transactions that do not result in ownership of the new option. The Funds’ ability to close out its position as a purchaser or seller of an OCC or exchange-listed put or call option is dependent, in part, upon the liquidity of the option market. Among the possible reasons for the absence of a liquid option market on an exchange are: (i) insufficient trading interest in certain options; (ii) restrictions on transactions imposed by an exchange; (iii) trading halts, suspensions or other restrictions imposed with respect to particular classes or series of options or underlying securities including reaching daily price limits; (iv) interruption of the normal operations of the OCC or an exchange; (v) inadequacy of the facilities of an exchange or OCC to handle current trading volume; or (vi) a decision by one or more exchanges to discontinue the trading of options (or a particular class or series of options), in which event the relevant market for that option on that exchange would cease to exist, although outstanding options on that exchange would generally continue to be exercisable in accordance with their terms. The hours of trading for listed options may not coincide with the hours during which the underlying instruments are traded. To the extent that the option markets close before the markets for the underlying instruments, significant price and rate movements can take place in the underlying markets that cannot be reflected in the option markets.

OTC options are purchased from or sold to securities dealers, financial institutions or other parties (“Counterparties”) through direct bilateral agreement with the Counterparty. In contrast to exchange-listed options, which generally have standardized terms and performance mechanics, all the terms of an OTC option are negotiated by the parties. The Funds generally expect to enter into OTC options that have cash settlement provisions, although they are not required to do so.

Equity swap transactions are entered into with financial intermediaries through a direct agreement with the Counterparty, generally an ISDA Master Agreement, the specific terms of which are negotiated by the parties. The Funds may use equity swaps, or other derivative instruments, for hedging purposes against potential adverse movements in security prices or for non-hedging purposes such as seeking to enhance return. The Funds may be required to post collateral for such transactions.

There is no central clearing or, unless the parties provide for it, guaranty function in an OTC option or derivative, including certain swaps. As a result, if the Counterparty fails to make or take delivery of the security or other instrument, or fails to make a cash settlement payment due in accordance with the option, the Funds will lose any premium they paid for the option as well as any anticipated benefit of the transaction. The Adviser must assess the creditworthiness of each Counterparty to determine the likelihood that the terms of the OTC option or the derivative will be satisfied. The Funds will engage in OTC option transactions and derivatives only with qualified Counterparties. The staff of the SEC currently takes the position that OTC options purchased by the Funds, and portfolio securities “covering” the amount of the Funds’ obligation pursuant to an OTC option sold by it (the cost of the sell-back plus any in-the-money amount) are illiquid and subject to the Funds’ limitations on investments in illiquid securities, unless the Funds have the legal right to terminate the option on not more than seven days notice and the Counterparty has a high credit quality rating.

10

Foreign Currency Transactions.

The Funds that are permitted to invest in foreign currency-denominated securities also may purchase and sell foreign currency options and foreign currency futures contracts and futures options, and they may engage in foreign currency transactions either on a spot (cash) basis at prevailing currency exchange rates or through forward currency contracts. These Funds may engage in these transactions to hedge, directly or indirectly, against currency fluctuations, for other investment purposes and, with respect to certain Funds, to seek to enhance returns. A Fund may enter into currency transactions only with counterparties that the Adviser deems to be creditworthy. Certain of the foreign currency transactions the Funds may use are described below.

Forward Foreign Exchange Transactions. Certain Funds may enter into forward currency contracts (“forwards”) in connection with settling purchases or sales of securities, to hedge the currency exposure associated with some or all of the Fund’s investments or as part of its investment strategy. Forwards are OTC contracts to purchase or sell a specified amount of a specified currency or multinational currency unit at a set price on a future date. The market value of a forward fluctuates with changes in foreign currency exchange rates. Forwards are marked to market daily based upon foreign currency exchange rates from an independent pricing service, and the change in value is recorded as unrealized appreciation or depreciation. A Fund will record a realized gain or loss when the forward is closed. Forwards are highly volatile, involve substantial currency risk and may also involve credit and liquidity risks.

Currency Futures. A Fund may also seek to enhance returns or hedge against the decline in the value of a currency through use of currency futures or options thereon. Currency futures are similar to forward foreign exchange transactions except that futures are standardized, exchange-traded contracts while forward foreign exchange transactions are traded in the OTC market. Currency futures involve substantial currency risk, and also involve leverage risk.

Currency Options. A Fund may also seek to enhance returns or hedge against the decline in the value of a currency through the use of currency options. Currency options are similar to options on securities. For example, in consideration for an option premium the writer of a currency option is obligated to sell (in the case of a call option) or purchase (in the case of a put option) a specified amount of a specified currency on or before the expiration date for a specified amount of another currency. A Fund may engage in transactions in options on currencies either on exchanges or OTC markets. A Fund may write covered call options on up to 100% of the currencies in its portfolio. Currency options involve substantial currency risk, and may also involve credit, leverage or liquidity risk.

Currency Swaps. In order to protect against currency fluctuations, a Fund may enter into currency swaps. A Fund may also hedge portfolio positions through currency swaps, which are transactions in which one currency is simultaneously bought for a second currency on a spot basis and sold for the second currency on a forward basis. Currency swaps involve the exchange of the rights of a Fund and another party to make or receive payments in specified currencies. Because currency swaps usually involve the delivery of the entire principal value of one designated currency in exchange for the other designated currency, the entire principal value of a currency swap is subject to the risk that the other party to the swap will default on its contractual delivery obligations.

Limitations on Currency Transactions. A Fund will not hedge a currency in excess of the aggregate market value of the securities that it owns (including receivables for unsettled securities sales), or has committed to purchase or anticipates purchasing, which are denominated in such currency. Open positions in forward foreign exchange transactions used for non-hedging purposes will be covered by the segregation of liquid assets and are marked to market daily.

Risk Factors in Hedging Foreign Currency. Hedging transactions involving currency instruments involve substantial risks, including correlation risk. While a Fund’s use of currency instruments to effect hedging strategies is intended to reduce the volatility of the net asset value of the Fund’s shares, the net asset value of the Fund’s shares will fluctuate. Moreover, although currency instruments will be used with the intention of hedging against adverse currency movements, transactions in currency instruments involve the risk that anticipated

11

currency movements will not be accurately predicted and that the Fund’s hedging strategies will be ineffective. To the extent that a Fund hedges against anticipated currency movements that do not occur, the Fund may realize losses and decrease its total return as the result of its hedging transactions. Furthermore, a Fund will only engage in hedging activities from time to time and may not be engaging in hedging activities when movements in currency exchange rates occur. In connection with its trading in forward foreign currency contracts, a Fund will contract with a foreign or domestic bank, or foreign or domestic securities dealer, to make or take future delivery of a specified amount of a particular currency. There are no limitations on daily price moves in such forward contracts, and banks and dealers are not required to continue to make markets in such contracts. There have been periods during which certain banks or dealers have refused to quote prices for such forward contracts or have quoted prices with an unusually wide spread between the price at which the bank or dealer is prepared to buy and that at which it is prepared.

Use of Derivatives, Segregated Accounts and Other Accounts.

Use of Derivatives.

Each Fund is operated by the Adviser in reliance on an exclusion, granted to operators of registered investment companies such as the Funds, from registration as a “commodity pool operator” (“CPO”), with respect to the Fund, under the Commodity Exchange Act (the “CEA”) and, therefore, is not subject to registration or regulation as a CPO under the CEA. The Funds may be limited in their ability to use commodity futures or options thereon, engage in certain swap transactions or make certain other investments (collectively, “commodity interests”) if the Adviser continues to claim the exclusion from the definition of CPO with respect to such Funds. In order for the Adviser to be eligible to continue to claimthis exclusion, if a Fund uses commodity interests other than for bona fide hedging purposes (as defined by the Commodity Futures Trading Commission (the “CFTC”)), the aggregate initial margin and premiums required to establish those positions (after taking into account unrealized profits and unrealized losses on any such positions and excluding the amount by which options are “in-the-money” at the time of purchase) may not exceed 5% of the Fund’s NAV, or, alternatively, the aggregate net notional value of those positions, as determined at the time the most recent position was established, may not exceed 100% of the Fund’s NAV (after taking into account unrealized profits and unrealized losses on any such positions). In addition to meeting one of the foregoing trading limitations, a Fund may not market itself as a commodity pool or otherwise as a vehicle for trading in the commodity futures, commodity options or swaps markets. Even if a Fund’s direct use of commodity interests complies with the trading limitations described above, the Fund may have indirect exposure to commodity interests in excess of such limitations. Such exposure may result from the Fund’s investment in other investment vehicles, including investment companies that are not managed by the Adviser or one of its affiliates, certain securitized vehicles that may invest in commodity interests and/or non-equity REITs that may invest in commodity interests (collectively, “underlying investment vehicles”). Because the Adviser may have limited or no information as to the commodity interests in which an underlying investment vehicle invests at any given time, the CFTC has issued temporary no-action relief permitting registered investment companies, such as the Funds, to continue to rely on the exclusion from the definition of CPO. The Adviser, on behalf of the Funds, has filed the required notice to claim this no-action relief. In order to rely on the temporary no-action relief, the Adviser must meet certain conditions and the Funds must otherwise comply with the trading and market limitations described above with respect to their direct investments in commodity interests.

Use of Segregated and Other Special Accounts.

Many hedging transactions require, among other things, that the Funds segregate liquid assets with their custodian to the extent Fund obligations are not otherwise “covered” through ownership of the underlying security or instrument. In general, either the full amount of any obligation by the Funds to pay or deliver securities or assets must be covered at all times by the securities or instruments required to be delivered, or, subject to any regulatory restrictions, an amount of cash or liquid securities at least equal to the current amount of the obligation must be segregated with the custodian. The segregated assets cannot be sold or transferred unless equivalent assets are substituted in their place or it is no longer necessary to segregate them.

12

Recent Regulation Regarding Derivatives and Segregated Accounts.

In October 2020, the SEC adopted new Rule 18f-4 under the 1940 Act, which governs the use of derivative investments and certain financing transactions (e.g. reverse repurchase agreements) by registered investment companies. Among other things, Rule 18f-4 will require funds that invest in derivative instruments beyond a specified limited amount to apply a value-at-risk based limit to their use of certain derivative instruments and financing transactions and to adopt and implement a derivatives risk management program. A fund that uses derivative instruments in a limited amount will not be subject to the full requirements of Rule 18f-4. In connection with the adoption of Rule 18f-4, funds will no longer be required to comply with the asset segregation framework arising from prior SEC guidance for covering certain derivative instruments and related transactions. Compliance with Rule 18f-4 will not be required until August 2022. As a Fund comes into compliance, the approach to asset segregation and coverage requirements described in this SAI will be impacted. Compliance with the new rule by a Fund could, among other things, make derivatives more costly, limit their availability or utility, or otherwise adversely affect their performance.

Special Situations.

The Funds may invest in “special situations.” A special situation arises when, in the opinion of the Adviser, the securities of a company will be recognized and appreciate in value due to a specific anticipated development at that company. Such developments might include a new product, a management change, an acquisition or a technological advancement. The risk of investing in special situations is that the anticipated development does not occur or its impact is not what the Adviser expected.

International Sanctions.

From time to time, certain of the companies in which a Fund invests may operate in, or have dealings with, countries subject to sanctions or embargoes imposed by the U.S. government and the United Nations and/or countries identified by the U.S. government as state sponsors of terrorism. A company may suffer damage to its reputation if it is identified as a company which operates in, or has dealings with, countries subject to sanctions or embargoes imposed by the U.S. government and the United Nations and/or countries identified by the U.S. government as state sponsors of terrorism. As an investor in such companies, the Fund will be indirectly subject to those risks.

Real Estate Industry Risk.

In addition to general market conditions, the value of the Funds will be affected by the strength of the real estate markets. Factors that could affect the value of the Funds’ holdings include the following: overbuilding and increased competition; increases in property taxes and operating expenses; declines in the value of real estate; lack of availability of equity and debt financing to refinance maturing debt; vacancies due to economic conditions and tenant bankruptcies; losses due to costs resulting from environmental contamination and its related clean-up; changes in interest rates; changes in zoning laws; casualty or condemnation losses; variations in rental income; changes in neighborhood values; and functional obsolescence and appeal of properties to tenants.

Share Classes.

The Funds offer three classes of shares, Retail Shares, Institutional Shares and R6 Shares, which differ only in their ongoing fees and eligibility requirements. Retail Shares are available to all investors, and account minimums range from $500 to $2,000, depending on the account type. Institutional Shares are for accounts in the amount of $1,000,000 or more per Fund. Institutional Shares are intended for certain financial intermediaries that offer shares of the Baron Funds^® through fee-based platforms, retirement platforms or other platforms for which the financial intermediary provides services and is not compensated by the Baron Funds^® for those services. Shareholders meeting the eligibility requirements for the Institutional Shares may also purchase Institutional Shares directly without paying a sales charge or any other additional fees. Baron WealthBuilder Fund,

13

employees/Directors of the Adviser and its affiliates and Trustees of the Baron Funds^® are not subject to the eligibility requirements for Institutional Shares. R6 Shares are available only to qualified 401(a) plans (including 401(k) plans, Keogh plans, profit-sharing plans, money purchase pension plans, target benefit plans, defined benefit pension plans and Taft-Hartley multi-employer pension plans) (collectively, “Qualified Plans”), endowment funds and foundations, any state, county or city, or its instrumentality, department, authority, or agency, 403(b) plans, 457 plans, including 457(a) governmental entity plans and tax-exempt plans, accounts registered to insurance companies, trust companies and bank trust departments, investment companies, both affiliated and not affiliated with the Adviser, and any entity that is considered a corporation for tax purposes, including corporate non-qualified deferred compensation plans of such corporations. R6 Shares are not available to traditional and Roth Individual Retirement Accounts, SEPs, SARSEPs and individual 403(b) plans. Institutional Shares are available to such accounts or plans to the extent they are purchased through an eligible fee-based program. R6 Shares are also not available to retail, advisory fee-based wrap programs or to adviser-sold donor-advised funds. There is no minimum initial investment for Qualified Plans; however, the shares must be held through plan-level or omnibus accounts held on the books of the Funds. All other R6 eligible investors must meet a minimum initial investment of at least $5,000,000 per Fund. For more information, please see the “How to Purchase Shares” section on pages 71-73 of the Prospectus. The Funds reserve the right, without prior notice, to change the eligibility requirements of its share classes, including the types of investors who are eligible to purchase each share class.

Disclosure of Portfolio Holdings.

The Board has adopted policies and procedures governing the disclosure of each Fund’s portfolio holdings.

Quarterly: The Funds post on the Baron Funds^® website, usually on the fifth business day after the quarter end, the top ten long positions held by each Fund, stated as a percentage of net assets (as a percentage of total long positions if the Fund is leveraged). In addition, the Funds post on the Baron Funds^® website, usually on the fifth business day after the quarter end, all long securities positions of each Fund’s net assets (as a percentage of total long positions if the Fund is leveraged) and the cash position at the most recent quarter end. All of this information will remain on the Baron Funds^® website until the next quarter end’s information is posted.

Monthly: In addition, the Funds post on the Baron Funds^® website, usually the tenth business day after month end, the ten largest long positions of each Fund, stated as a percentage of net assets (as a percentage of total long positions if the Fund is leveraged). This information will remain on the Baron Funds^® website until the next month end’s information is posted.

The Funds disclose portfolio holdings in connection with the day-to-day operations and management of the Funds, including to the Funds’ custodian (daily) and auditors (annually). Portfolio holdings may also be disclosed to other service providers of the Funds, including pricing services (daily), portfolio management and trading systems (daily) and proxy voting systems (quarterly). In these situations, the Funds, the Adviser or the Funds’ distributor, Baron Capital, Inc. (“BCI” or the “Distributor”), have entered into agreements with service providers whereby they agree to keep the information confidential and to refrain from trading on the basis of the information. When engaged in purchasing and selling securities for the Funds through brokers, dealers or other financial intermediaries, the Funds disclose certain information about one or more of the securities positions they own. The Funds do not have separate non-disclosure agreements with these entities, but the Funds would immediately cease doing business with any entity that the Adviser believes is misusing the information.

Other information that may be of interest to investors, such as industry breakdowns and a historical analysis of security impact, may be available on the Baron Funds^® website. The website address is www.BaronFunds.com. The link to Fund information is www.BaronFunds.com/products. Holdings information for each Fund can be accessed from this link.

A Fund may release the portfolio information to persons earlier than the dates stated above only if certain members of senior management of the Fund determine that the release of such information is in the best interest of the Fund’s shareholders, that there is a legitimate business purpose and where the recipient agrees in writing to maintain the confidentiality of the information and not to trade on the information.

If the Funds inadvertently release the information prior to the dates stated above to any person, and there was no agreement as described, the Funds will promptly post the information to the website. A Fund may also release what the Adviser reasonably believes to be immaterial information as the Adviser deems appropriate.

18

No employee of the Funds or the Adviser is allowed to accept compensation or consideration in any form with respect to the release of the of Funds’ portfolio holdings. “Consideration” includes any agreement to maintain assets in the Funds or in other investment companies or accounts managed by the Adviser. Any exceptions to any of the Funds’ disclosure policies are reported to the Board.

MANAGEMENT OF THE FUNDS

Board of Trustees and Officers.

The Board’s role in management of the Trust is oversight. As is the case with virtually all investment companies (as distinguished from operating companies), service providers to the Trust, primarily the Adviser and its affiliates, have responsibility for the day-to-day management of the Funds, which includes responsibility for risk management (including management of investment performance and investment risk, valuation risk, issuer and counterparty credit risk, cybersecurity risk, compliance risk and operational risk). As part of its oversight, the Board, acting at its scheduled meetings, regularly interacts with and receives reports from senior personnel of service providers, including the Adviser. The Board’s Audit Committee (which consists of three trustees who are not affiliated with the Adviser (“Independent Trustees”)) meets regularly with the Trust’s independent registered public accounting firm and the Trust’s Chief Financial Officer. The Board also receives periodic presentations from senior personnel of the Adviser or its affiliates regarding risk management generally, as well as periodic presentations regarding specific operational, compliance or investment areas, such as business continuity, anti-money laundering, personal trading, valuation, credit, investment research and securities lending. The Board has adopted policies and procedures designed to address certain risks to the Funds. In addition, the Adviser and other service providers to the Funds have adopted a variety of policies, procedures and controls designed to address particular risks to the Funds. However, it is not possible to eliminate all of the risks applicable to the Funds. The Board also receives reports from counsel to the Adviser and the Board’s own independent legal counsel regarding regulatory compliance and governance matters. The Board’s oversight role does not make the Board a guarantor of the Trust’s investments or activities.

The 1940 Act requires that at least 40% of the Funds’ trustees not be “interested persons” (as defined in the 1940 Act) of the Funds, and to rely on certain exemptive rules under the 1940 Act, a majority of the Funds’ trustees must not be interested persons of the Funds. For certain important matters, such as the approval of investment advisory agreements or transactions with affiliates, the 1940 Act or the rules thereunder require the approval of a majority of the Trustees who are Independent Trustees. Currently, seven of the Trustees are not interested persons of the Trust (as such, the Trustees are not affiliated with the Adviser). The Chairman of the Board, Linda Martinson, is an interested person of the Trust (“Interested Trustee”), and the Independent Trustees have designated a lead Independent Trustee who chairs meetings or executive sessions of the Independent Trustees, reviews and comments on Board meeting agendas, represents the views of the Independent Trustees to management and facilitates communication among the Independent Trustees and their independent legal counsel. The Board has determined that its leadership structure, in which the Independent Trustees have designated a lead Independent Trustee to function as described above is appropriate in light of the services that the Adviser and its affiliates provide to the Trust and potential conflicts of interest that could arise from these relationships.

Trustees of the Trust, together with information as to their positions with the Trust, principal occupations and other board memberships and affiliations for the past five years, are shown below. Each Trustee serves as Trustee of a Fund until its termination; until the Trustee’s retirement, resignation or death; or as otherwise specified in the Trust’s organizational documents. Unless otherwise noted, the address of each Executive Officer and Trustee is Baron Investment Funds Trust, 767 Fifth Avenue, 49th Floor, New York, NY 10153. All Trustees listed below, whether Interested or Independent, serve as Trustees for the Trust.

⁽¹⁾  Trustees deemed to be “Interested Trustees” by reason of their employment with the Adviser and BCI.

⁽²⁾  Members of the Executive Committee, which is empowered to exercise all of the powers, including the power to declare dividends, of the full Board when the full Board is not in session.

Each Trustee, except for Anita Rosenberg, who was appointed as a Trustee in May of 2013, Thomas J. Folliard, who was appointed as Trustee in August of 2017, Abraham (Avi) Nachmany and Marvelle Sullivan, who were appointed as Trustees in May of 2020, and Errol Taylor, who was appointed as Trustee in December of 2020, has been a Board member of the Trust and other Baron mutual funds for at least 16 years. In addition, the following are among some of the specific experiences, qualifications, attributes or skills that each Trustee possesses supplementing the information provided in the table above. The Board believes that the significance of each Trustee’s experience, qualifications, attributes or skills is an individual matter (meaning that experience that is important for one Trustee may not have the same value for another) and that these factors are best evaluated at the Board level, with no single Trustee, or particular factor, being indicative of Board effectiveness. However, the Board believes that Trustees need to have the ability to critically review, evaluate, question and discuss information provided to them, and to interact effectively with Adviser and Trust management, service providers and counsel, in order to exercise effective business judgment in the performance of their duties; the Board

22

believes that its members satisfy this standard. Experience relevant to having this ability may be achieved through a Trustee’s educational background; business, professional practice (e.g., medicine, accounting or law), public service or academic positions; experience from service as a board member (including the Board of the Trust) or executive of investment funds, public companies or significant private or not-for-profit entities or other organizations; and/or other life experiences. To assist them in evaluating matters under federal and state law, the Trustees are counseled by their own independent legal counsel, who participates in Board meetings and interacts with the Adviser. The Trustees also may benefit from information provided by the Adviser’s counsel. Counsel to the Independent Trustees has significant experience advising funds and fund board members. The Audit Committee of the Board and their independent legal counsel meets regularly with the Trust’s independent registered public accounting firm, and the Board and its committees have the ability to engage other experts as appropriate. The Board evaluates its performance on an annual basis.

The Independent Trustees do not own any securities of the Adviser, the Distributor or any other entity controlling, controlled by or under common control with the Adviser or Distributor.

Code of Ethics.

The Funds, the Adviser and the Distributor have adopted a written Code of Ethics pursuant to Rule 17j-1 under the 1940 Act. The Code of Ethics prohibits employees from investing in securities held by the Funds.

Proxy Voting Policies and Procedures.

The Funds have delegated all decision making on proxy voting to the Adviser. The Adviser makes its own independent voting decisions, although it may consider recommendations from third parties in its decision-making process. The Adviser makes voting decisions solely in the best interests of the Funds and their shareholders. It is the policy of the Adviser in voting proxies to vote each proposal with the goal of maximizing long-term investment returns for the Funds.

The Adviser uses guidelines which are reviewed quarterly by a Proxy Review Committee established by the Adviser. While the Adviser makes investment decisions based, in part, on the strength of a company’s management team, it will not automatically support management proposals if such proposals are inconsistent with the Adviser’s Proxy Voting Policies and Procedures.

If it is determined that there is a potential material conflict of interest between the interests of the Adviser and the interests of a Fund, the Proxy Review Committee will review the matter and may either (i) request that the Fund consent to the Adviser’s vote, (ii) vote in accordance with the published recommendations of an independent proxy voting service, or (iii) appoint an independent third party to vote.

A full copy of the Adviser’s Proxy Voting Policies and Procedures is available on the Baron Funds^® website, www.BaronFunds.com under “Legal Notices” link at the bottom left corner of the homepage. The Funds’ most current Proxy Voting Record on Form N-PX for the twelve months ended June 30, 2021 is also available on the Baron Funds^® website or on the SEC’s website at www.sec.gov.

INVESTMENT ADVISORY AND OTHER SERVICES

Investment Adviser.

The Adviser to the Funds, BAMCO, is a New York corporation with its principal offices at 767 Fifth Avenue, New York, NY 10153 and a subsidiary of BCG. Mr. Baron is the controlling stockholder of BCG. Mr. Baron has over 51 years of experience as a Wall Street analyst and has managed money for others for over 46 years. Mr. Baron is the lead portfolio manager for Baron Growth Fund and was the co-portfolio manager of Baron Asset Fund until January 23, 2008. Mr. Baron is also the portfolio manager of Baron Partners Fund, Baron Focused Growth Fund and Baron WealthBuilder Fund, each a series of Baron Select Funds.

Pursuant to separate Advisory Agreements with each Fund (each an “Advisory Agreement,” and collectively the “Advisory Agreements”), the Adviser furnishes continuous investment advisory services and management to the Funds, including making the day-to-day investment decisions and arranging portfolio transactions for the Funds, subject to such policies as determined by the Board. For such services, the Adviser receives an annual fee from Baron Asset Fund, Baron Growth Fund, Baron Small Cap Fund, Baron Opportunity Fund and Baron Discovery Fund of 1% of the average daily net assets of the respective Fund. Baron Fifth Avenue Growth Fund pays the Adviser 0.70% for average daily net assets of the Fund. Baron Durable Advantage Fund pays the Adviser 0.65% for average daily net assets of the Fund. The Adviser has contractually agreed to limit the expense ratio (excluding portfolio transaction costs, interest, dividend and extraordinary expenses), for as long as the Adviser serves as investment adviser to the Funds, for each of the share classes as follows:

Fund	Retail Shares			Institutional Shares			R6 Shares
Baron Asset Fund		N/A			N/A			N/A

31

Under the Advisory Agreements, the Adviser, at its own expense and without reimbursement from the Funds, furnishes office space and all necessary office facilities, equipment and executive personnel for managing the Funds, and pays the salaries and fees of all Officers and Trustees who are interested persons of the Adviser.

The Adviser also uses a portion of its assets to pay all or a portion of the charges of third parties that distribute shares of the Funds to their customers.

The Funds pay all operating and other expenses not borne by the Adviser such as: audit, accounting and legal fees; custodian fees; expenses of registering and qualifying their shares with federal and state securities commissions; expenses in preparing shareholder reports and proxy solicitation materials; expenses associated with the Funds’ shares, such as dividend disbursing, transfer agent and registrar fees; certain insurance expenses; compensation of Independent Trustees and other miscellaneous business expenses. The Funds also pay the expenses of offering the shares of the Funds, including the registration and filing fees, legal and accounting fees and costs of printing the Prospectus and related documents. The Funds also pay all taxes imposed on them and all brokerage commissions and expenses incurred in connection with their portfolio transactions.

The Adviser utilizes the staffs of BCG and its subsidiary BCM to provide research. Directors, Officers or employees of the Adviser and/or its affiliates may also serve as Officers or Trustees of the Funds or of other funds managed by the Adviser. BCM is an investment adviser to institutional and individual accounts. Clients of BCM and the other funds managed by the Adviser have investment goals which may or may not vary from those of each other and of the Funds. BCM and the Adviser invest in substantially similar or the same securities as the Funds, other client accounts and in the accounts of principals and employees of BCM and its affiliates. When the same securities are purchased for or sold by the Funds and any of such other accounts, it is the policy of the Adviser and BCM to allocate such transactions in a manner deemed equitable by the Adviser. All personal trading by employees is subject to the Code of Ethics of the Funds and the Adviser. In certain circumstances, the Adviser may make investments for the Funds that conflict with investments being made by BCM. The Adviser may also make investment decisions for the Funds that are inconsistent with the investment decisions for other Funds it manages.

Each Advisory Agreement provides that the Funds may use “Baron” as part of its name for so long as the Adviser serves as the investment adviser to the Funds. The Funds acknowledge that the word “Baron” in its name is derived from the name of the entities controlling, directly or indirectly, the Adviser, which derive their name from Ronald Baron, that such name is the property of the Adviser and its affiliated companies for copyright and/or other purposes, and that if for any reason the Adviser ceases to be the Funds’ investment adviser, the Funds will promptly take all steps necessary to change their name to one that does not include “Baron,” unless they receive the Adviser’s written consent to continue using the name.

Each Advisory Agreement provides that the Adviser shall have no liability to the Funds or their shareholders for any error of judgment or mistake of law or for any loss suffered by the Funds on account of any action taken in good faith, provided that the Adviser shall not be protected against liabilities arising by virtue of willful misfeasance, bad faith or gross negligence, or reckless disregard of the Adviser’s obligations under the Advisory Agreements.

Each Advisory Agreement is terminable without penalty by the relevant Fund (when authorized by a majority vote of the shareholders or the Trustees) or the Adviser on 60 days’ written notice. The Advisory Agreements shall automatically terminate in the event of their “assignment” (as defined by the 1940 Act).

Principal Underwriter.

The Funds have a distribution agreement with BCI with its principal offices located at 767 Fifth Avenue, New York, NY 10153. BCI is an affiliate of BAMCO.

32

Distribution and Servicing Agreements.

The Funds and/or the Distributor have agreements with various financial intermediaries pursuant to which various services may be provided to the Funds or their shareholders. See “Distribution and Servicing Arrangements” in the Prospectus.

12b-1 Plan.¹

The Distributor does not receive underwriting commissions, but the Funds’ distribution and servicing plan for Retail Shares adopted pursuant to Rule 12b-1 under the 1940 Act (the “12b-1 Plan”) authorizes the Funds to pay the Distributor a distribution and servicing fee equal to 0.25% per annum of each Fund’s average daily net assets attributable to the Retail Shares. The 12b-1 fees are paid to the Distributor in connection with (a) activities and expenses primarily intended to result in the sale of Retail Shares and/or the servicing of Retail Shares shareholder accounts and/or (b) providing services to holders of Retail Shares of the Funds and/or maintaining accounts in the Retail Shares of the Funds, including, but not limited to, (i) compensation to financial intermediaries (as described in the Prospectus) that have entered into an agreement with the Distributor; (ii) compensation to and expenses of registered representatives and/or employees of the Distributor who engage in or support distribution of Retail Shares or who service shareholder accounts; and (iii) printing of prospectuses and reports for other than existing holders of Retail Shares; preparation, printing and distribution of sales literature and advertising materials for Retail Shares; and telephone expenses and other identifiable expenses in connection with the foregoing. The total amount of the 12b-1 fee is payable to the Distributor, regardless of the actual expenses incurred, which expenses may be more or less than the 12b-1 fees received by the Distributor.

The 12b-1 Plan requires that the Trust will cause to be provided to the Board a written report, at least quarterly, of the amounts of all expenditures pursuant to the 12b-1 Plan and related agreements, and the purposes for which such expenditures were made for the preceding fiscal quarter.

For the fiscal year ended September 30, 2021, the Funds paid fees attributable to Retail Shares to the Distributor under the 12b-1 Plan as follows: Baron Asset Fund, $7,012,901; Baron Growth Fund, $7,259,067; Baron Small Cap Fund, $4,351,478; Baron Opportunity Fund, $2,109,557; Baron Fifth Avenue Growth Fund, $470,915; Baron Discovery Fund, $629,082 and Baron Durable Advantage Fund, $14,832.

The following table shows the amounts that were paid by the Distributor under the 12b-1 Plan for the fiscal year ended September 30, 2021. All amounts were paid to third parties for distribution and/or shareholder servicing.

	Baron Asset Fund		Baron Growth Fund		Baron Small Cap Fund		Baron Opportunity Fund		Baron Fifth Avenue Growth Fund		Baron Discovery Fund		Baron Durable Advantage Fund
Distribution and Service Fees Paid to Third Parties	$	7,012,901	$	7,259,067	$	4,351,478	$	2,109,557	$	470,915	$	629,082	$	14,832

The Independent Trustees have no direct or indirect financial interest in the operation of the 12b-1 Plan or any agreement thereunder. The Interested Trustees have such an interest.

The 12b-1 Plan has been approved by the Board, including a majority of the Independent Trustees. In approving the 12b-1 Plan, the Board considered various factors and determined that there is a reasonable likelihood that the 12b-1 Plan will benefit the Funds and their Retail Shares shareholders. The anticipated benefits include the following: (i) the likelihood of attracting and retaining investments in the Retail Shares; (ii) the potential benefits of a larger asset base, including reduced expenses; and (iii) potential benefits to investors in the Retail Shares of the services to be provided pursuant to the 12b-1 Plan.

¹  The 12b-1 plan applies to Retail Shares only. It does not apply to Institutional Shares or R6 Shares.

33

Unless terminated in accordance with its terms, the 12b-1 Plan will continue in effect for a one year period, and from year to year thereafter if such continuance is specifically approved at least annually by the Board and by the Independent Trustees, with such votes being cast in person at a meeting called for the purpose of such vote.

The 12b-1 Plan may be terminated at any time by the vote of a majority of the Independent Trustees or by the vote of a majority of the outstanding Retail Shares. The 12b-1 Plan may not be amended to increase materially the amount of payments to be made without the approval of holders of the Funds’ Retail Shares. All material amendments must be approved by a vote of the Board and of the Independent Trustees, with such votes being cast in person at a meeting called for the purpose of such vote. If the 12b-1 Plan is terminated, the Funds will owe no payments to the Distributor, other than any unpaid portion of the 12b-1 fee accrued through the effective date of termination.

Potential Conflicts of Interest.

Conflicts of interest could arise in connection with managing the Funds along with other Baron Funds^® and the accounts of other clients of the Adviser and of clients of the Adviser’s affiliated investment adviser, BCM. Because of market conditions, client investment restrictions, Adviser imposed investment guidelines and the consideration of factors such as cash availability and diversification considerations, not all investment opportunities will be available to the Funds and all clients at all times. The Adviser has joint trading policies and procedures designed to ensure that no Fund or client is systematically given preferential treatment over time. The Funds’ Chief Compliance Officer monitors allocations for consistency with this policy and reports to the Board annually. Because an investment opportunity may be suitable for multiple accounts, the Funds may not be able to take full advantage of that opportunity because the opportunity may be allocated among many or all of the Funds and accounts of clients managed by the Adviser and its affiliate.

To the extent that the Funds’ portfolio manager has responsibilities for managing other client accounts, the portfolio manager may have conflicts of interest with respect to his time and attention among relevant accounts. In addition, differences in the investment restrictions or strategies among a Fund and other accounts may cause

36

the portfolio manager to take action with respect to another account that differs from the action taken with respect to the Funds. In some cases, another account managed by the portfolio manager may provide more revenue to the Adviser. While this may create additional conflicts of interest for the portfolio manager in the allocation of management time, resources and investment opportunities, the Adviser takes all necessary steps to ensure that the portfolio manager endeavors to exercise his discretion in a manner that is equitable to the Funds and other accounts.

The Adviser believes that it has policies and procedures in place that address the Funds’ potential conflicts of interest. Such policies and procedures address, among other things, trading practices (e.g., brokerage commissions, cross trading, aggregation and allocation of transactions, sequential transactions, allocations of orders for execution to brokers and portfolio performance dispersion review), disclosure of confidential information and employee trading.

Compensation.

Mr. Baron has an employment agreement that includes a fixed base salary and a performance bonus, the ultimate amount of which is determined by the Compensation Committee of the BCG Board of Directors, in its sole discretion. The terms of his contract are based on Mr. Baron’s role as the Firm’s Founder and Chief Executive Officer, and his position as portfolio manager for the majority of the Firm’s assets under management. Consideration is given to Mr. Baron’s reputation, the long-term performance records of the Funds under his management and the profitability of the Firm.

The compensation for Messrs. Greenberg, Peck, Lippert, Umansky, Bieger, Gwirtzman and Rosenberg includes a base salary and an annual bonus that is based, in part, on the amount of assets they manage, as well as their individual long-term investment performance, their overall contribution to the Firm and the Firm’s profitability. In addition, Messrs. Greenberg and Peck own equity in BCG. They are also eligible for special bonuses based on the Firm achieving its long-term growth and profitability goals.

Ownership of Portfolio Managers.

As of September 30, 2021, the Portfolio Manager ownership of Fund shares was:

BROKERAGE ALLOCATION AND OTHER PRACTICES

For the Fiscal Year Ended September 30,	2021		2020		2019
Total Commissions Paid by the Fund
Baron Asset Fund	$	385,552	$	224,801	$	385,662
Baron Growth Fund		320,141		413,337		458,483
Baron Small Cap Fund		1,361,760		1,344,815		1,098,049
Baron Opportunity Fund		677,592		274,551		179,803
Baron Fifth Avenue Growth Fund		193,150		37,613		35,873
Baron Discovery Fund		1,663,908		657,207		820,295
Baron Durable Advantage Fund		1,640		434		339

The variation in the commissions paid by the Funds year-to-year are caused by fluctuating trading volume.

The Adviser is responsible for placing the portfolio brokerage business of the Funds. Purchase and sale orders are placed with brokers that the Adviser believes will achieve “best execution” of such orders. Best execution involves consideration of a number of factors, including direct net economic results to the Funds, the efficiency with which the transaction is executed, the ability to effect the transaction in the size and price range requested, the ability to effect the transaction with minimum impact on the market, the financial strength and stability of the broker, the broker’s familiarity with a particular security, the broker’s commitment of resources to executing the transaction and past experience with a broker.

Under the Advisory Agreements and as permitted by Section 28(e) of the Securities and Exchange Act of 1934, the Adviser may cause the Funds to pay a broker that provides brokerage and research services to the Adviser an amount of commission for effecting a securities transaction for the Funds in excess of the amount that other brokers would have charged for the transaction, if the Adviser determines in good faith that the greater commission is consistent with the Funds’ policies and is reasonable in relation to the value of the brokerage and research services provided by the executing broker or third party pursuant to a Commission Sharing Arrangement viewed in terms of either a particular transaction or the Adviser’s overall responsibilities to the Funds or to its other clients. The term “brokerage and research services” includes advice as to the value of securities, the advisability of investing in, purchasing, or selling securities, and the availability of securities or of purchasers or sellers of securities, furnishing analyses and reports concerning issuers, industries and securities, economic factors and trends, portfolio strategy and the performance of accounts; and effecting securities transactions and performing functions incidental thereto, such as clearance and settlement. Such services may be used by the Adviser or its affiliate to supplement the services it is required to perform pursuant to the Advisory Agreement in serving the Funds and/or other advisory clients of the affiliate.

Brokers may be willing to furnish statistical research and other factual information or services to the Adviser for no consideration other than brokerage or underwriting commissions. Research provided by brokers is used for the benefit of all of the Adviser’s or its affiliate’s clients and not solely or necessarily for the benefit of the Funds. The Adviser’s investment management personnel attempt to evaluate the quality of research provided by brokers. Results of this effort may be used by the Adviser as a consideration in the selection of brokers to execute portfolio transactions.

Investment decisions for the Funds and for other client accounts managed by BCM and the Adviser are made independent of each other in light of differing considerations for the various accounts. The same investment decision may, however, be made for two or more of the Adviser’s and/or BCM’s accounts. When this occurs, simultaneous transactions are inevitable. Purchases and sales are averaged as to price where possible and allocated to accounts in a manner deemed equitable by the Adviser in conjunction with BCM. This procedure could have a detrimental or beneficial effect upon the price or value of the security for the Funds, depending upon market conditions.

CAPITAL STOCK AND OTHER SECURITIES

Baron Investment Funds Trust (formerly known as Baron Asset Fund) is an open-end investment company organized as a series fund and established under the business trust law of The Commonwealth of Massachusetts. The seven series currently available are Baron Asset Fund, Baron Growth Fund, Baron Small Cap Fund, Baron Opportunity Fund, Baron Fifth Avenue Growth Fund, Baron Discovery Fund and Baron Durable Advantage Fund. Shares entitle their holders to one vote per share on all matters submitted to a vote of shareholders. The Trust’s Declaration of Trust provides that no matters need be submitted to shareholders except as required by the 1940 Act. Consequently, matters such as mergers, acquisitions and sales of assets may not require shareholder approval. In the election of Trustees, shares have non-cumulative voting rights, which means that holders of more than 50% of the shares voting for the election of Trustees can elect all Trustees and, in such event, the holders of the remaining shares voting for the election of Trustees will not be able to elect any person or persons as Trustees. Shares have no preemptive or subscription rights and are transferable.

Under Massachusetts law, shareholders of a Massachusetts business trust may, under certain circumstances, be held personally liable as partners for the obligations of the trust. The Declaration of Trust contains an express disclaimer of shareholder liability for acts or obligations of the Fund or any series thereof. Notice of such disclaimer will normally be given in each agreement, obligation or instrument entered into or executed by the Funds or Trustees. The Declaration of Trust provides for indemnification by a Fund for any loss suffered by a shareholder as a result of an obligation of that Fund. The Declaration of Trust also provides that a Fund shall, upon request, assume the defense of any claim made against any shareholder for an act or obligation of that Fund and satisfy any judgment thereon. Thus, the risk of a shareholder incurring financial loss on account of shareholder liability is limited to circumstances in which the Fund itself would be unable to meet its obligations. The Trustees believe that, in view of the above, the risk of personal liability of shareholders is remote.

The Declaration of Trust further provides that the Trustees will not be liable for errors of judgment or mistakes of fact or law, but nothing in the Declaration of Trust protects a Trustee against liability to which he or she would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his or her office.

PURCHASE, REDEMPTION AND PRICING OF SHARES

The Funds expect to make all redemptions in cash but reserve the right to make payment, in whole or in part, in portfolio securities. Payment will be made other than all in cash if the Board determines that economic conditions exist which would make a cash payment detrimental to the Funds’ best interests. Portfolio securities to be so distributed, if any, would be selected in the discretion of the Board and priced as described under “How Your Shares are Priced” in the Prospectus.

As more fully set forth in the Prospectus under “How Your Shares are Priced,” the net asset value per share (“NAV”) of each Fund is calculated as of the scheduled close of the regular trading session (usually 4 p.m. E.T. or such other time as of which the Funds’ NAV is calculated (the “NAV Calculation Time”)) on the New York Stock Exchange (the “Exchange”) on any day the Exchange is scheduled to be open. The Exchange is open all weekdays that are not holidays. Annually, the Exchange publishes the holidays on which it will be closed. The most recent announcement states it will not be open on New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas Day.

Securities traded on more than one national securities exchange are valued at the last sale prices of the day as of which such value is being determined as reflected at the close of the exchange that is the principal market for such securities. For Securities traded on NASDAQ, the Funds use the NASDAQ Official Closing Price. If there are no sales on a given day, the value of the security may be the average of the most recent bid and asked quotations on such exchange or the last sale price from a prior day.

39

U.S. Government obligations, money market instruments, and other debt instruments having 60 days or less remaining until maturity generally are valued at amortized cost. Debt instruments having a greater remaining maturity will be valued on the basis of prices obtained from an independent pricing service or at the mean between the bid and ask prices from a dealer maintaining an active market in that security. The value of the Funds’ investments in convertible bonds is determined primarily by obtaining valuations from independent pricing services based on readily available bid quotations or, if quotations are not available, by methods which include various considerations such as yields or prices of securities of comparable quality, coupon, maturity and type; indications as to values from dealers; and general market conditions. Other inputs used by an independent pricing service to value convertible bonds generally include underlying stock data, conversion premiums, listed bond and preferred stock prices and other market information which may include benchmark curves, trade execution data, and sensitivity analysis, when available. Money market instruments held by the Funds with a remaining maturity of 60 days or less are valued at amortized cost, which approximates fair value, unless an independent pricing service provides a valuation for such security or in the opinion of the board or a committee or other persons designated by the board, the amortized cost method would not represent fair value. Open-end investment companies, including securities lending collateral invested in registered investment company money market funds, are valued at their NAV each day.

Non-U.S. equity securities are valued on the basis of their most recent closing market prices and translated into U.S. dollars at the NAV Calculation Time except under the circumstances described below. Most foreign markets close before the NAV Calculation Time. For securities primarily traded in the Far East, for example, the most recent closing prices may be as much as 15 hours old at the NAV Calculation Time. As a result, the Adviser uses a third-party pricing service to assist in determining fair value of foreign securities. This service utilizes a systematic methodology in making fair value estimates. The Adviser may also fair value securities in other situations, for example, when a particular foreign market is closed but the Funds are open. The Adviser cannot predict how often it will use closing prices and how often it will adjust those prices. As a means of evaluating its fair value process, the Adviser routinely compares closing market prices, the next day’s opening prices in the same markets, and the adjusted prices. Other mutual funds may adjust the prices of their securities by different amounts.

TAXATION OF THE FUNDS

The Prospectus contains information about the U.S. federal income tax consequences of ownership of shares. Certain supplementary information is presented below. References below to the “Fund” apply to each of the Funds described in the Prospectus.

U.S. Federal Income Taxation.

The following information is based on the Internal Revenue Code of 1986, as amended (the “Code”), Treasury Regulations, administrative rulings and judicial decisions as of the date hereof, all of which may be changed either retroactively or prospectively. This discussion does not address all aspects of U.S. federal income taxation that may be relevant to shareholders in light of their particular circumstances (such as alternative minimum tax consequences or Medicare contribution tax consequences) or to shareholders subject to special treatment under U.S. federal income tax laws (such as certain financial intermediaries, insurance companies, dealers in stock or securities, tax-exempt organizations, persons who have entered into hedging transactions with respect to shares of the Fund and persons who borrow in order to acquire shares). Prospective shareholders should consult their tax advisors with respect to the particular tax consequences to them of an investment in the Fund.

This discussion addresses only shareholders who hold Fund shares as capital assets within the meaning of Section 1221 of the Code (generally, for investment). Except where specifically addressing foreign shareholders, this discussion assumes that the shareholder is (i) an individual who is a citizen or resident of the United States; (ii) a corporation, or other entity treated as a corporation for U.S. federal income tax purposes, that was created or organized in or under the laws of the United States, any state therein or the District of Columbia; or (iii) an estate or trust the income of which is subject to U.S. federal income taxation regardless of its source. If an entity that is classified as a partnership for U.S. federal income tax purposes holds shares of the Fund, the U.S. federal income tax treatment of a partner will generally depend on the status of the partner and the activities of the

40

partnership. Partnerships holding Fund shares and partners in such partnerships should consult their tax advisors as to the particular U.S. federal income tax consequences to them of holding and disposing of such shares.

Tax Status of the Funds.

The Fund has elected to qualify, and intends to remain qualified, as a regulated investment company under Subchapter M of the Code. Qualification as a regulated investment company requires, among other things, that (a) at least 90% of the Fund’s annual gross income be derived from interest; dividends; payments with respect to certain securities loans; gains from the sale or other disposition of stock, securities or foreign currencies; other income (including gains from options, futures or forward contracts) derived with respect to its business of investing in such stock, securities or currencies; and net income from interests in “qualified publicly traded partnerships,” as defined in the Code (any such income “Qualifying Income”); and (b) the Fund diversify its holdings so that, at the end of each quarter of the taxable year, (i) at least 50% of the market value of the Fund’s assets is represented by cash, U.S. government securities and other securities limited in respect of any one issuer to an amount not greater than 5% of the value of the Fund’s total assets and not more than 10% of the outstanding voting securities of such issuer, and (ii) not more than 25% of the value of its total assets is invested in the securities of any one issuer (other than U.S. government securities and securities of other regulated investment companies), of two or more issuers that are controlled by the Fund and that are engaged in the same or similar trades or businesses or related trades or businesses, or of one or more “qualified publicly traded partnerships.”

Qualification and election as a “regulated investment company” involve no supervision of investment policy or management by any government agency. As a regulated investment company, the Fund generally will not be subject to U.S. federal income tax on income that is distributed to shareholders, provided that the Fund distributes to its shareholders at least 90% of its “investment company taxable income” (determined prior to the deduction for dividends paid by the Fund) and 90% of its net tax-exempt interest income for each taxable year. The Fund’s “investment company taxable income” for any taxable year is its taxable income, determined without regard to net capital gain (that is, the excess of net long-term capital gain over net short-term capital loss) for such taxable year and with certain other adjustments. Assuming that the Fund meets the 90% distribution requirement, it will generally be subject to tax at regular U.S. federal corporate income tax rates only on any income or gain that it does not distribute in a timely manner.

The Fund intends to make sufficient distributions in a timely manner in order to ensure that it will not be subject to the nondeductible 4% U.S. federal excise tax that is imposed on certain undistributed income of regulated investment companies. In general, in order for the Fund to avoid the 4% U.S. federal excise tax, the Fund must distribute in each calendar year at least (i) 98% of its ordinary income for the calendar year, (ii) 98.2% of its capital gain net income for the one-year period ending on October 31 of the calendar year and (iii) any ordinary income and capital gains for previous years that were not distributed during those years. For purposes of determining whether the Fund has met this distribution requirement, (i) certain ordinary gains and losses that would otherwise be taken into account for the portion of the calendar year after October 31 will be treated as arising on January 1 of the following calendar year and (ii) the Fund will be deemed to have distributed any income or gains on which it paid U.S. federal income tax.

If for any taxable year the Fund did not qualify for the special U.S. federal income tax treatment afforded to regulated investment companies (for example, by not meeting the 90% distribution requirement described above), all of its taxable income would be subject to U.S. federal income tax at regular corporate rates (without any deduction for distributions to its shareholders) and all distributions out of its current or accumulated earnings and profits would be taxable as dividend income. In such event, provided that a shareholder satisfied the applicable holding period and other requirements with respect to his shares, dividend distributions would be eligible for the dividends-received deduction in the case of a corporate shareholder, and if received by a non-corporate shareholder, would be taxable to the shareholder as “qualified dividend income,” which is subject to tax at the rates applicable to long-term capital gain (currently, a maximum rate of 20%). In addition, the Fund could be required to recognize unrealized gains, pay taxes and make distributions (which could be subject to interest charges) before requalifying for taxation as a regulated investment company. However, if the Fund fails

41

to satisfy the income test or diversification test described above, the Fund may be able to avoid losing its status as a regulated investment company by timely providing notice of such failure to the Internal Revenue Service (the “IRS”), curing such failure and possibly paying an additional tax.

The Fund may invest in shares of certain foreign corporations that may be classified under the Code as passive foreign investment companies (“PFICs”). In the absence of one of the elections described below, if the Fund receives certain distributions from a PFIC, or gain from the sale of PFIC stock, the Fund may be subject to a tax on such distributions or gain, as well as to interest charges. In order to mitigate these adverse consequences, the Fund will generally make an election to mark-to-market its shares of PFICs. At the end of each taxable year to which the election applies, the Fund will report as ordinary income the amount by which the fair market value of its shares in a PFIC for which the Fund has made a mark-to-market election exceeds the Fund’s adjusted basis in those shares. If the Fund’s adjusted basis in the shares of such a PFIC exceeds the shares’ fair market value at the end of a taxable year, the Fund will be entitled to a deduction equal to the lesser of (a) this excess and (b) the Fund’s aggregate income inclusions in respect of such stock under the mark-to-market rules that have not been previously offset by mark-to-market losses. As a result of a mark-to-market election, the Fund will not recognize any capital gains with respect to its investment in the relevant PFIC stock. Alternatively, the Fund may under certain circumstances elect to include as income and gain its share of the ordinary earnings and net capital gain of certain PFICs, without regard to whether it receives any distributions from these PFICs.

Certain other investments made by the Fund, such as investments in debt securities that have original issue discount, will cause the Fund to recognize income for U.S. federal income tax purposes prior to the Fund’s receipt of the corresponding distributable proceeds. In addition, some of the Fund’s investments, such as the Fund’s transactions in foreign currencies, forward contracts, options, and futures contracts (including options and futures contracts on foreign currencies) will be subject to special provisions of the Code that, among other things, may affect the character of gains and losses realized by the Fund (i.e., may affect whether gains or losses are ordinary or capital), accelerate recognition of income by the Fund or defer Fund losses. These provisions may result in the Fund’s “marking-to-market” certain types of positions in its portfolio (i.e., treating them as if they were sold at the end of each taxable year). The application of these rules to the Fund could affect the character, amount and timing of distributions to shareholders.

The Fund may thus recognize income without receiving cash with which to make distributions in amounts necessary to satisfy the distribution requirements for avoiding income and excise taxes. In that case, the Fund may have to dispose of other securities and use the proceeds to make distributions in order to satisfy these distribution requirements.

Foreign Taxes.

Dividends, interest and capital gains received by the Fund may give rise to withholding and other taxes imposed by foreign countries. Such taxes will reduce shareholders’ return. Income tax treaties between certain countries and the United States may reduce or eliminate such taxes, but there can be no guarantee that the Fund will qualify for treaty benefits.

Under the Code, if more than 50% of the value of the Fund’s total assets at the close of the taxable year consists of stock or securities of foreign corporations, the Fund may file an election with the IRS to “pass-through” to the Fund’s shareholders the amount of foreign income taxes paid by the Fund. Pursuant to this election, a shareholder would (a) include in gross income (in addition to dividends actually received) his pro rata share of the foreign income taxes paid by the Fund; (b) treat his pro rata share of such foreign income taxes as having been paid by him; and (c) subject to certain limitations, be entitled either to deduct his pro rata share of such foreign income taxes in computing his taxable income or to use it as a foreign tax credit against U.S. income taxes. Shortly after any year for which it makes such an election, the Fund will report to its shareholders, in writing, the amount per share of such foreign tax that must be included in each shareholder’s gross income and the amount which will be available for deduction or credit.

42

Generally, a credit for foreign income taxes is subject to the limitation that it may not exceed the shareholder’s U.S. tax liability (before the credit) attributable to the shareholder’s total foreign-source taxable income. If the Fund makes the “pass-through” election, the portion of dividends paid by the Fund from its foreign-source income (e.g., dividends paid by foreign companies) will be treated as foreign-source income. The Fund’s gains and losses from the sale of securities, and its foreign currency gains and losses, will generally be treated as derived from U.S. sources. The limitation on the foreign tax credit is applied separately to foreign-source “passive income,” including the portion of dividends received from the Fund that qualifies as foreign- source income. Because of these limitations, a shareholder may be unable to claim a credit for the full amount of the shareholder’s pro rata share of the foreign income taxes paid by the Fund. A shareholder’s ability to claim a credit for foreign taxes paid by the Fund may also be limited by holding period requirements applicable both to the Fund’s investment in the foreign shares and to the shareholder’s investment in Fund shares.

If the Fund does not meet the requirements of the Code necessary to make the “pass-through” election or does not make the election, any foreign taxes paid or accrued will represent an expense to the Fund, which will reduce its investment company taxable income. Absent this election, shareholders will not be able to claim either a credit or deduction for their pro rata shares of such taxes paid by the Fund, nor will shareholders be required to treat their pro rata shares of such taxes as amounts distributed to them.

Distributions.

Distributions to shareholders of the Fund’s investment company taxable income (other than “qualified dividend income”), including distributions of net short-term capital gains, will be taxable as ordinary income to shareholders. Distributions (or deemed distributions, as described below) of the Fund’s net capital gains will be taxable to shareholders as long-term capital gains, regardless of the length of time the shares have been held by a shareholder. Long-term capital gains recognized by individuals and other non-corporate shareholders are currently subject to U.S. federal income tax at lower rates than the rates applicable to ordinary income. Distributions in excess of the Fund’s current and accumulated earnings and profits will, as to each shareholder, be treated as a tax-free return of capital to the extent of such shareholder’s adjusted basis in his shares, and as a capital gain thereafter. The ultimate tax characterization of the Fund’s distributions made in a taxable year cannot be determined until after the end of the taxable year. As a result, there is a possibility that the Fund may make total distributions during a taxable year in an amount that exceeds the current and accumulated earnings and profits of the Fund.

Provided that the shareholder satisfies the applicable holding period and other requirements with respect to his shares, (i) distributions of the Fund’s “qualified dividend income” will be treated as “qualified dividend income” received by an individual or other non-corporate shareholder and will therefore be subject to U.S. federal income tax at the rates applicable to long-term capital gain and (ii) shareholders that are corporations may be entitled to claim a dividends-received deduction for the portion of Fund distributions that is attributable to certain dividend income received by the Fund.

If the Fund retains any net capital gains for reinvestment, it may elect to treat such capital gains as having been distributed to its shareholders. If the Fund makes such an election, each shareholder will be required to include its share of such undistributed net capital gain in income as long-term capital gain and will be entitled to claim its share of the U.S. federal income taxes paid by the Fund on such undistributed net capital gain as a credit against its own U.S. federal income tax liability, if any, and to claim a refund on a properly-filed U.S. federal income tax return to the extent that the credit exceeds such liability. In addition, each shareholder will be entitled to increase the adjusted tax basis of its Fund shares by the difference between its share of such undistributed net capital gain and the related credit. There can be no assurance that the Fund will make this election if it retains all or a portion of its net capital gain for a taxable year. A shareholder’s tax liability for such distributions will depend on the shareholder’s particular tax situation.

Shareholders who instruct the Fund to reinvest distributions in additional shares will be treated for U.S. federal income tax purposes as receiving the relevant distributions and using them to purchase shares. Thus,

43

distributions of investment company taxable income and net capital gains, whether received in cash or reinvested, must be reported by the shareholder on his U.S. federal income tax return.

Distributions by the Fund result in a reduction in the net asset value of the Fund’s shares. Should a distribution reduce the net asset value below a shareholder’s cost basis, such distribution could nevertheless be taxable to the shareholder as ordinary income or capital gain as described above, even though, from an investment standpoint, it may constitute a partial return of capital. In particular, investors should consider the tax implications of buying shares just prior to a distribution. Although the price of shares purchased at the time will include the amount of the forthcoming distribution, the distribution will nevertheless be taxable to the purchaser.

As of September 30, 2021, the Funds had no capital loss carryforwards.

Sale or Redemption of Shares.

A shareholder will recognize a taxable gain or loss, if any, if the shareholder sells or redeems his shares. Such gain or loss will be equal to the difference between his adjusted tax basis in the shares sold or redeemed and the amount of the cash or the fair market value of other property (including securities distributed by the Fund) received by him in payment therefor.

Any gain or loss arising from the sale or redemption of shares will be treated as capital gain or loss, and will generally be long-term capital gain or loss if the shareholder’s holding period for the shares is more than one year and short-term capital gain or loss if it is one year or less. Long-term capital gains recognized by individuals and other non-corporate shareholders on a sale or redemption of shares generally will be taxed at a maximum rate of 20%. Any loss realized on a sale or redemption will be disallowed to the extent the shares disposed of are replaced (including pursuant to our dividend reinvestment program) with substantially identical shares within a period beginning 30 days before and ending 30 days after the disposition of the shares. In such a case, the basis of the shares acquired will be adjusted to reflect the disallowed loss. Any loss arising from the sale or redemption of shares for which the shareholder has a holding period of six months or less will be treated for U.S. federal tax purposes as a long-term capital loss to the extent of any amount of capital gain dividends received by the shareholder with respect to such shares. For purposes of determining a shareholder’s holding period of shares, the holding period will be suspended for any periods during which the shareholder’s risk of loss is diminished as a result of holding one or more other positions in substantially similar or related property or through certain options or short sales.

A shareholder who recognizes a loss on a sale or other disposition of shares will be required to report the sale or other disposition on IRS Form 8886 if the loss exceeds an applicable threshold amount. Failure to comply with the reporting requirements gives rise to substantial penalties. Certain states, including New York, may also have similar disclosure requirements. Shareholders should consult their tax advisors to determine whether they are required to file IRS Form 8886 in connection with a sale or other disposition of shares.

Exchange or Conversion of Shares.

You may exchange all or a portion of your shares in one Fund for shares in another Fund. Exchanges will be executed on the basis of the relative net asset value of the shares exchanged. An exchange will be considered a sale for U.S. federal income tax purposes, and you may therefore realize a gain or loss for U.S. federal income tax purposes as a result of an exchange. The Funds offer three classes of shares, Retail Shares, Institutional Shares and R6 Shares, which differ only in their ongoing fees and eligibility requirements. You may convert Retail Shares into Institutional Shares if the value of your investment in a Fund is at least $1,000,000. If the value of your investment in a Fund falls below $1,000,000 because of redemptions, the Fund may convert your Institutional Shares into Retail Shares. You may convert Retail Shares or Institutional Shares into R6 Shares if you meet the eligibility requirements. The transaction will be based on the respective net asset value per share of each class on the trade date for the conversion. For U.S. federal income tax purposes, such a conversion will not be a taxable event. You should consult your own tax adviser regarding specific questions of federal, state, local or foreign tax law.

44

Backup Withholding and Information Reporting.

Payments on the shares and proceeds from a redemption or other disposition of shares will generally be subject to information reporting. Such amounts will be subject to backup withholding at the rate of 28% if payable to shareholders who fail to provide the Fund (or other payor) with their correct taxpayer identification numbers or to make required certifications, or who have been notified by the IRS that they are subject to backup withholding. Certain types of shareholders are exempt from such backup withholding. Backup withholding is not an additional tax. Any amounts withheld may be credited against a shareholder’s U.S. federal income tax liability.

Foreign Shareholders.

A “foreign shareholder” is an investor that, for U.S. federal income tax purposes, is a nonresident alien individual, a foreign corporation, or a foreign estate or trust. This disclosure assumes that (i) a foreign shareholder’s ownership of shares in the Fund is not effectively connected with a trade or business conducted by such foreign shareholder in the United States, (ii) the foreign shareholder is not an expatriate of the United States, (iii) the foreign shareholder does not own, and has not owned, actually or constructively, more than 5% of the Fund’s shares and (iv) the foreign shareholder is not an individual who is present in the United States for 183 days or more in any taxable year. A distribution of the Fund’s investment company taxable income to a foreign shareholder, including a deemed distribution as a consequence of a Fund’s election to pass through foreign taxes paid by the Fund, will generally be subject to withholding tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty. Provided that certain requirements are satisfied, this withholding tax will not be imposed on dividends paid by the Fund to the extent that the underlying income out of which the dividends are paid consists of U.S.-source interest income or short-term capital gains that would not have been subject to U.S. withholding tax if received directly by the foreign shareholder (“interest-related dividends” and “short-term capital gain dividends,” respectively).

Foreign shareholders may be subject to an increased U.S. federal income tax on their income resulting from a Fund’s election (described above) to “pass-through” amounts of foreign taxes paid by the Fund, but may not be able to claim a credit or deduction with respect to the withholding tax for the foreign taxes treated as having been paid by them.

Information returns will be filed with the IRS in connection with certain payments on the shares. A foreign shareholder may be subject to U.S. backup withholding on distributions that are otherwise exempt from withholding tax or on the proceeds from a redemption or other disposition of shares if such foreign shareholder does not certify its non-U.S. status under penalties of perjury or otherwise establish an exemption. Backup withholding is not an additional tax. Any amounts withheld pursuant to the backup withholding rules will be allowed as a credit against the foreign shareholder’s U.S. federal income tax liability, if any, and may entitle the foreign shareholder to a refund, provided that the required information is furnished to the IRS on a timely basis.

In order to qualify for the exemption from U.S. withholding tax on “interest-related dividends” and “short-term capital gain dividends” (if any), to qualify for an exemption from U.S. backup withholding and to qualify for a reduced rate of U.S. withholding tax on Fund dividends under an income tax treaty, a foreign shareholder must generally deliver to the relevant Fund or other withholding agent a properly executed IRS form (generally, Form W-8BEN or Form W-8BEN-E, as applicable). In order to claim a refund of any Fund-level taxes imposed on undistributed net capital gains, any U.S. withholding taxes or any backup withholding on Fund distributions, a foreign shareholder must obtain a U.S. taxpayer identification number and file a U.S. federal income tax return.

None of the Funds expects to be a “United States real property holding corporation” for U.S. federal income tax purposes. Foreign shareholders should consult their tax advisors regarding the potential tax consequences to them if any relevant Fund is or was a “United States real property holding corporation.”

The tax consequences to a foreign shareholder entitled to claim the benefits of an applicable tax treaty may be different from those described herein. Foreign shareholders are advised to consult their own tax advisor with respect to the particular tax consequences to them of an investment in the Fund.

45

Under Sections 1471 through 1474 of the Code (“FATCA”), a withholding tax at the rate of 30% will generally be imposed on payments to certain foreign entities (including financial intermediaries) of dividends on Fund shares and on gross proceeds from the sale or other disposition made to a foreign entity unless the foreign entity provides the withholding agent with certifications and other information (which may include information relating to ownership by U.S. persons of interests in, or accounts with, the foreign entity). If FATCA withholding is imposed, a beneficial owner of shares that is not a foreign financial institution (as specifically defined for purposes of FATCA) generally may obtain a refund of any amounts withheld by filing a U.S. federal income tax return (which may entail significant administrative burden). Foreign shareholders should consult their tax advisors regarding the possible implications of FATCA on their investment in the Fund.

State, Local and Foreign Taxes.

In addition to federal income taxes, shareholders of the Fund may be subject to state, local or foreign taxes on distributions from the Fund and on repurchases or redemptions of shares. Shareholders should consult their tax advisors as to the application of such taxes and as to the tax status of distributions from the Fund and repurchases or redemptions of shares in their own states and localities.

Cost Basis Information.

The Fund is required to report your cost basis, gain or loss, and holding period to the IRS on Form 1099 when “covered” shares of the Fund are redeemed. Covered shares are any shares acquired (including shares acquired through reinvestment of the Fund’s distributions) on or after January 1, 2012. The Fund has chosen the “average cost” method as its default method for reporting the cost basis of covered shares. The Fund will use this method for purposes of reporting your cost basis unless you instruct the Fund in writing to use a different calculation method. You may choose a method different from the Fund’s default method if you provide the Fund with timely notice. Please consult your tax advisor with regard to your particular circumstances.

UNDERWRITERS

BCI is the principal underwriter responsible for distributing the Funds’ securities. The Funds’ public offering of their securities is continuous, and BCI is obligated to distribute the Funds’ securities on a best efforts basis. BCI does not receive underwriting commissions from the Funds. The 12b-1 Plan authorizes the Funds to pay the Distributor a distribution fee equal to 0.25% per annum of each Fund’s average daily net assets attributable to the Retail Shares.

No shareholder shall be subject to any personal liability whatsoever to any Person in connection with Trust Property or the acts, obligations or affairs of the Trust. No Trustee, officer, employee or agent of the Trust shall be subject to any personal liability whatsoever to any Person, other than to the Trust of its shareholders, in connection with Trust Property of the affairs of the Trust, save only that arising from bad faith, willful misfeasance, gross negligence or reckless disregard of his duties with respect to such Person; and all such Persons shall look solely to the Trust Property, or to the Property of one or more specific series of the Trust if the claim arises from the conduct of such Trustee, officer, employee or agent with respect to only such Series, for satisfaction of claims of any nature arising in connection with the affairs of the Trust. If any shareholder, Trustee, officer, employee, or agent, as such, of the Trust, is made a party to any suit or proceeding to enforce any such liability of the Trust, he shall not, on account thereof, be held to any personal liability. The Trust shall indemnify and hold each shareholder harmless from and against all claims and liabilities, to which such shareholder may become subject by reason of his being or having been a shareholder, and shall reimburse such shareholder out of the Trust Property for all legal and other expenses reasonably incurred by him in connection with any such claim or liability. Indemnification and reimbursement required by the preceding sentence shall be made only out of assets of the one of more Series whose shares were held by said shareholder at the time the act or event occurred which gave rise to the claim against or liability of said shareholder. The rights accruing to a shareholder under this Section 4.1 be lawfully entitled, nor shall anything herein contained restrict the right of the Trust to indemnify or reimburse a shareholder in any appropriate situation even though not specifically provided herein.

Section 4.2. Non-Liability of Trustees, Etc.

No Trustee, officer, employee or agent of the Trust shall be liable to the Trust, its shareholders, or to any shareholder, Trustee, officer, employee, or agent thereof for any action or failure to act (including without limitation the failure to compel in any way any former or acting Trustee to redress any breach of trust) except for his own bad faith, willful misfeasance, gross negligence or reckless disregard of the duties involved in the conduct of his office.

Section 4.3. Mandatory Indemnification.

(a) Subject to the exceptions and limitations contained in paragraph (b) below:

(i) every person who is, or has been, a Trustee or officer of the Trust shall be indemnified by the Trust, or by one or more Series thereof if the claim arises from his or her conduct with respect to only such Series to the fullest extent permitted by law against all liability and against all expenses reasonably incurred or paid by him in connection with any claim, action, suit or proceeding in which he becomes involved as a party or otherwise by virtue of his being or having been a Trustee or officer and against amounts paid or incurred by him in the settlement thereof;

(ii) the words “claim,” “action,” “suit,” or “proceeding” shall apply to all claims, actions, suits or proceedings (civil, criminal, or other, including appeals), actual or threatened; and the words “liability” and “expenses” shall include, without limitation, attorneys’ fees, costs, judgments, amounts paid in settlement, fines, penalties and other liabilities.

(b) No indemnification shall be provided hereunder to a Trustee or officer:

(i) against any liability to the Trust or a Series thereof or the shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office;

(ii) with respect to any matter as to which he shall have been finally adjudicated not the have acted in good faith in the reasonable belief that his action was in the best interest of the Trust or a Series thereof;

(iii) in the event of a settlement or other disposition not involving a final adjudication as provided in paragraph (b)(ii) resulting in a payment by a Trustee or officer, unless there has been a determination that such Trustee or officer did not engage in willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office:

(A) by the court or other body approving the settlement or other disposition; or

C-3

(B) based upon a review of readily available facts (as opposed to a full trial-type inquiry) by (x) vote of a majority of the Non-interested Trustees acting on the matter (provided that a majority of the Non-interested Trustees then in office act on the matter) or (y) written opinion of independent legal counsel.

(c) The rights of indemnification herein provided may be insured against by policies maintained by the Trust, shall be severable, shall not affect any other rights to which any Trustee or officer may now or hereafter be entitled, shall continue as to a person who has ceased to be such Trustee or officer and shall inure to the benefit of the heirs, executors, administrators and assigns of such a person. Nothing contained herein shall affect any rights to indemnification to which personnel of the Trust other than Trustees and officers may be entitled by contract or otherwise under law.

(d) Expenses of preparation and presentation of a defense to any claim, action, suit or proceeding of the character described in paragraph (a) of this Section 4.3 may be advanced by the Trust or a Series thereof prior to final disposition thereof upon receipt of an undertaking by or on behalf of the recipient to repay such amount if it is ultimately determined that he is not entitled to indemnification under this Section 4.3, provided that either:

(i) such undertaking is secured by a surety bond or some other appropriate security provided by the recipient, or the Trust or Series thereof shall be insured against losses arising out of any such advances; or

(ii) a majority of the Non-interested Trustees acting on the matter (provided that a majority of the Non-interested Trustees act on the matter) or an independent legal counsel in a written opinion shall determine, based upon a review of readily available facts (as opposed to a full trial-type inquiry), that there is reason to believe that the recipient ultimately will be found entitles to indemnification.

As used in this Section 4.3, a “Non-interested Trustee” is one who is not (i) an “Interested Person” of the Trust (including anyone who has been exempted from being an “Interested Person” by any rule, regulation or order of the Commission), or (ii) involved in the claim, action, suit or proceeding.

Section 4.4. No Bond Required of Trustees.

No Trustee shall be obligated to give any bond or other security for the performance of any of his duties hereunder.

Section 4.5. No Duty of Investigation; Notice in Trust Instruments, Etc.

No purchaser, lender, transfer agent or other Person dealing with the Trustees or any officers, employee or agent of the Trust or a Series thereof shall be bound to make any inquiry concerning the validity of any transaction purporting to be made by the Trustees or by said officer, employee or agent or be liable for the application of money or property paid, loaned, or delivered to or on the order of the Trustees or of said officer, employee or agent. Every obligation, contract, instrument, certificate, Share, other security of the Trust or a Series thereof or undertaking, and every other act or thing whatsoever executed in connection with the Trust shall be conclusively presumed to have been executed or done by the executors thereof only in their capacity as Trustees under this Declaration or in their capacity as officers, employees or agents of the Trust or a Series thereof. Every written obligation, contract, instrument, certificate, Share, other security of the Trust or a Series thereof or undertaking made or issued by the Trustees may recite that the same is executed or made by them not individually, but as Trustees under the Declaration, and that the obligations of the Trust or a Series thereof under any such instrument are not binding upon any of the Trustees or Shareholders individually, but bind only the Trust Property or the Trust Property of the applicable Series, and may contain any further recital which they or he may deem appropriate, but the omission of such recital shall not operate to bind the Trustees individually. The Trustees shall at all times maintain insurance for the protection of the Trust Property or the Trust Property of the applicable Series, its Shareholders, Trustees, officers, employees and agents in such amount as the Trustees shall deem adequate to cover possible tort liability, and such other insurance as the Trustees in their sole judgment shall deem advisable.

Section 4.6. Reliance on Experts, Etc.

Each Trustee and officer of the Trust or employee of the Trust or a Series thereof shall, in the performance of his duties, be fully and completely justified and protected with regard to any act or any failure to act resulting from reliance in good faith upon the books of account or other records of the Trust or a Series thereof, upon an opinion of counsel, or upon reports made to the Trust or a Series thereof by any of its officers or employees or by the Investment Adviser, the Administrator, the Distributor, Transfer Agent, selected dealers, accountants, appraisers or other experts or consultants selected with reasonable care by the Trustees, officers or employees of the Trust, regardless of whether such counsel or expert may also be a Trustee.

C-4

Insofar as the indemnification for liabilities arising under the Securities Act of 1933, as amended, (the “1933 Act”) may be permitted to the officers, trustees or controlling persons of the Registrant pursuant to the Declaration of Trust of the Registrant or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the 1933 Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by an officer or trustee or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such officer, trustee or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question of whether such indemnification by it is against public policy as expressed in the 1933 Act and will be governed by the final adjudication of such issue.

Item 31. Business and Other Connections of the Investment Adviser

The business and other connections of BAMCO, Inc. is summarized under “Management of the Fund” in the Prospectus constituting Part A of the Registration Statement, which summary is incorporated herein by reference.

767 Fifth Avenue

New York, NY 10153

RE:    $200,000,000 Committed Line of Credit

Ladies and Gentlemen:

State Street Bank and Trust Company (the “Bank”) has previously made available a $100,000,000 committed, unsecured revolving line of credit (the “Committed Line”) to Baron Investment Funds Trust, a Massachusetts business trust, and Baron Select Funds, a Delaware statutory trust, registered under the Investment Company Act (the “Existing Borrower”), on behalf of certain of their fund series, pursuant to that certain Committed Line of Credit Agreement, dated January 28, 2015, by and between the Existing Borrower and the Bank (as amended prior to the date hereof, the “Existing Loan Agreement”).

The parties hereto have agreed to amend the Existing Loan Agreement as set forth below. Therefore, for good and valuable consideration, the receipt of which is hereby acknowledged, the Bank is pleased to make available a $200,000,000 committed unsecured revolving line of credit (the “Committed Line”) on a several basis to each of the Borrowers, each acting separately on behalf of each of its respective Funds on a several, not joint and several, basis subject to terms of Section I(5)(c) hereof, on the following terms and conditions:

I. Committed Line.

1.    Term. The Committed Line shall expire June 30, 2022 (the “Expiration Date”), unless extended by mutual agreement of the Bank and the Borrowers or, with respect to any Fund, terminated by the applicable Borrower on behalf of such Fund as provided herein. A Borrower, on behalf of a Fund, may terminate the Committed Line with respect to such Fund upon three (3) days’ prior written notice and payment of all outstanding principal, interest, fees, costs, expenses and other amounts owing by such Fund to the Bank hereunder on the effective date of termination.

2.    Notice and Manner of Borrowings. Subject to the terms and conditions hereof, the Bank shall make revolving loans to a Borrower, on behalf of any Fund, under the Committed Line (each such loan, a “Loan”) up to a maximum aggregate principal amount outstanding at any one time equal to the Committed Line Amount; provided that, in each case after giving effect to the requested Loan, (i) the aggregate outstanding Indebtedness for borrowed money of such Fund (including the aggregate principal amount of all Loans outstanding to such Fund) shall not exceed the Maximum Amount applicable to such Fund, (ii) the aggregate principal amount of Loans outstanding to such Fund hereunder shall not exceed the Committed Line Amount, and (iii) the aggregate principal amount of Loans outstanding to all Borrowers on behalf of all Funds hereunder shall not exceed the Committed Line Amount. Each request for a Loan hereunder, shall be in a minimum amount of $100,000 or an integral of $100,000 in excess thereof and shall be made in writing by any Borrower, on behalf of a Fund, by delivering a completed loan request

January 28, 2015

Page 2

in the form of Exhibit B attached hereto and such other information or documentation as the Bank may reasonably request. Each such Loan request shall be made by any Borrower, on behalf of a Fund, and received by the Bank not later than 3:00 p.m., Boston time, on the Business Day on which such Loan is to be made. Each Loan request hereunder shall be deemed to be a confirmation by the applicable Borrower, on behalf of the applicable Fund, that no Default or Event of Default has occurred and is continuing hereunder with respect to such Borrower or such Fund, that the representations and warranties of the Borrower, on behalf of such Fund, described below remain true and correct, and that no borrowing limitations or restrictions applicable to such Fund or the Committed Line (including those set forth in the provisos above in this Section) will be exceeded after giving effect to the requested Loan, each of which shall be a precondition to the making of any Loan hereunder.

3.     Evidence of Indebtedness.

(a) The Loans made by the Bank to the Borrowers shall be evidenced by one or more loan accounts or records maintained by the Bank in the ordinary course of business. Each Borrower, on behalf of its respective Funds, irrevocably authorizes the Bank to make or cause to be made, at or about the date of each Loan to such Borrower or at the time of receipt of any payment of principal of each such Loan, an appropriate notation on its loan accounts or records, including computer records, reflecting the making of such Loan or (as the case may be) the receipt of such payment. The outstanding amount of the Loans set forth in any such loan accounts or records, including any computer records, maintained by the Bank with respect to the Loans made by it shall, absent manifest error, be prima facie evidence of the principal amount thereof owing and unpaid to the Bank, but the failure to record, or any error in so recording, any such amount on any such loan account or record shall not limit or otherwise affect the obligation of each of the Borrowers, on behalf of each of its respective Funds, hereunder or under the other Loan Documents to make payments of principal of, and interest on, the Loans when due.

(b) Each Borrower hereby agrees that, upon request of the Bank, such Borrower shall promptly execute and deliver to the Bank, a promissory note (as amended, supplemented or otherwise modified, the “Note”) substantially in the form of Exhibit A attached hereto, payable to the Bank in an amount equal to the Committed Line Amount or, if less, the aggregate unpaid principal amount of the Bank’s Loans, plus interest thereon as provided below, which shall evidence the Bank’s Loans in addition to such records.

(c) In recognition of the Bank now evidencing the Loans by one or more loan accounts or records maintained by the Bank in the ordinary course of business in accordance with Section I(3)(a), after the effectiveness of this letter amendment, the Bank shall return to the Borrowers, if requested, the Amended and Restated Promissory Note, dated January 28, 2015, made by one or more of the Borrowers and payable to the Bank in its possession as of December 16, 2019 (the “Existing Note”), marked “Cancelled”. The cancellation of the original Existing Note shall not be deemed to evidence the repayment or satisfaction of any existing Loans or related Obligations, all of which shall thereafter be evidenced by one or more loan accounts or records maintained by the Bank as so described in Section I(3)(a) or, if requested by the Bank under Section I(3)(b), the Note.

January 28, 2015

4.    Interest Rate. Principal on each outstanding Loan shall bear interest at a variable rate per annum equal to the Applicable Rate plus the Applicable Margin, which rate shall be subject to change from time to time as and when the Applicable Rate changes. Interest on each Loan shall be calculated on the basis of a 360-day year for the actual number of days elapsed. Following and during the continuance of a Default or an Event of Default hereunder with respect to a Fund, unpaid principal on any Loan to such Fund, and to the extent permitted by applicable law, unpaid interest on any Loan to such Fund, shall thereafter bear interest, compounded monthly and payable on demand, until paid in full (after as well as before judgment) at a rate per annum equal to two percent (2%) above the rate otherwise applicable to such Loan hereunder, but not to exceed the maximum rate permitted by law.

5.    Payments and Prepayments; Recourse.

(a) Subject to the terms of Section I.5(c), each of the Borrowers, on behalf of its respective Funds, hereby severally promises to pay accrued interest on all Loans made to such Fund monthly in arrears on the fifteenth day of each calendar month for the immediately preceding calendar month; provided, however, that in each such case if such day on which interest on any Loans is due is not a Business Day, interest shall be payable on the next preceding Business Day. Subject to the terms of Section I.5(c), each of the Borrowers, on behalf of its respective Funds, hereby severally promises to repay the principal amount of each outstanding Loan made to such Fund, together with all accrued and unpaid interest thereon, upon the earliest of (i) 60 days following the date on which such Loan is made, (ii) the date on which such Loan becomes due pursuant to Section II(4) below following the occurrence of an Event of Default with respect to such Fund, or (iii) the Expiration Date. Each of the Borrowers, on behalf of each of its respective Funds, further covenants and agrees to immediately repay (1) the outstanding aggregate principal amount of any Indebtedness for borrowed money of any such Fund at any time (including the then outstanding aggregate principal amount of all Loans to such Fund) to the extent such amount exceeds the Maximum Amount applicable to such Fund at such time, and (2) any amount by which the then outstanding aggregate principal amount of all Loans to any such Fund at any time exceeds the Committed Line Amount, in each case upon the earlier to occur of such Borrower first becoming aware of any such circumstance or demand by the Bank. Each of the Borrowers, on behalf of each of its respective Funds having Loans outstanding at any time, further covenants and agrees that it shall make such repayments of the Loans outstanding to each such Fund at any time to the extent required such that the then outstanding aggregate principal amount of all Loans to all Funds hereunder shall at no time exceed the Committed Line Amount upon the earlier to occur of such Borrower first becoming aware of any such circumstance or demand by the Bank. Loans may be prepaid at the option of the Borrowers without penalty or premium, and any amounts prepaid may be reborrowed. Notwithstanding the foregoing or any other provision of this Agreement, there shall be a period with respect to each Fund hereunder consisting of at least one Business Day during each sixty (60) day period during which this Agreement is in effect when no Loans are outstanding to such Fund. Each of the Borrowers, on behalf of its respective Funds, promises to make such payments of one or more Loans as are necessary to comply with the foregoing sentence.

January 28, 2015

(b) All payments by the Borrowers on behalf of their respective Funds hereunder and under any of the other Loan Documents shall be made not later than 3:00 p.m. Boston time on the date due in immediately available United States dollars at the Bank’s office at One Lincoln Street, Boston, Massachusetts 02111 or as otherwise directed in writing by the Bank. Each Borrower hereby authorizes and irrevocably directs the Bank, at the Bank’s option at any time upon and following the due date for payment by such Borrower of any amounts under the Loan Documents, and without any further notice to or consent of such Borrower, to debit any account(s) of such Borrower with the Bank and apply amounts so debited toward the payment of any such amounts due and owing by such Borrower under the Loan Documents. Notwithstanding such authorization and direction, each Borrower hereby further acknowledges and agrees that (i) the Bank shall have no obligation to so debit any such account(s) and shall have no liability whatsoever to such Borrower for any failure to do so, and (ii) such Borrower shall fully retain the obligation under the Loan Documents to make all payments thereunder when due. All such payments by the Borrowers on behalf of their respective Funds hereunder and under any of the other Loan Documents shall be made without recoupment, setoff or counterclaim and free and clear of and without deduction for any taxes, levies, imposts, duties, charges, fees, deductions, withholdings, compulsory loans, restrictions or conditions of any nature now or hereafter imposed or levied by any jurisdiction or any political subdivision thereof or taxing or other authority therein unless a Borrower is compelled by law to make such deduction or withholding. If any such obligation is imposed upon a Borrower with respect to any amount payable by it hereunder or under any of the Loan Documents, such Borrower will pay to the Bank, on the date on which such amount is due and payable hereunder or under the Loan Documents, such additional amount in United States dollars as shall be necessary to enable the Bank to receive the same net amount which the Bank would have received on such due date had no such obligation been imposed upon such Borrower. The applicable Borrower will deliver promptly to the Bank certificates or other valid vouchers for all taxes or other charges deducted from or paid with respect to payments made by such Borrower hereunder or under the Loan Documents.

(c) The Bank and each of the Borrowers acknowledge and agree that the Bank shall look solely to the property of each respective Fund for the enforcement of any claim against such Fund. None of the trustees, officers, employees, agents or shareholders of the Borrowers or any respective Fund assumes any personal liability for the obligations entered into by the Borrowers, on behalf of their respective Funds, with respect to the Committed Line. In addition, the principal amount of any Loan, and accrued interest thereon, and any fees, costs, expenses, indemnities or other amounts payable in connection with or relating to any Fund or any Loan pursuant to this Agreement (other than any fees, costs, expenses, indemnities or other amounts payable to the Bank pursuant to the terms hereof not specific or identifiable to any Fund or Funds or any particular Loan), shall be paid or repaid solely from the assets of such Fund (or, in the case of any Fund which is a series of a Borrower, the series to which such Loan is made), and the Bank shall have no right of recourse or offset against the assets of any other Fund or any other series of any Borrower for such amounts. Each Fund shall be severally (and not jointly) liable to the Bank hereunder for fees, costs, expenses, indemnities or other amounts owed to the Bank pursuant to the terms hereof that are not specific or identifiable to any Fund or Funds or any particular Loan in accordance with such Fund’s pro rata portion thereof based upon the relative Net Assets of each of the Funds or based upon such other method as the board of directors or trustees of the respective Borrowers, including a majority of the non-interested trustees, shall determine is fair and equitable and in the best interests of each of the participating Funds, in each case with prior written notice to the Bank.

6.    Use of Loan Proceeds. Proceeds of Loans may be used solely for temporary or emergency purposes, including, without limitation, to temporarily finance the redemption of the shares of an investor of a Fund, or to temporarily finance the purchase or sale of securities by a Fund for prompt delivery if the Loan is to be repaid promptly in the ordinary course of business upon completion of such purchase or sale transaction, or for other temporary and emergency purposes in each case consistent with the then current investment objectives/goals and investment restrictions of a Fund; provided that such use of proceeds of each such Loan (a) shall constitute an “Exempted Transaction” as described in section 221.6(f) of Regulation U, (b) shall otherwise constitute an “Exempted Transaction” under, or shall not constitute a “purpose credit” for purposes of, Regulation U, or (c) shall not otherwise cause such Loans to violate the provisions of Regulation U. In the event that the proposed use of proceeds of any Loan to any Fund shall not constitute an “Exempted Transaction” under Regulation U, but shall nonetheless constitute a “purpose credit” for purposes thereof, the Borrower, on behalf of such Fund, at the time of the request for such Loan is made, shall furnish the Bank with an updated statement in conformity with the requirements of Federal Reserve Form U-1 referred to in Regulation U. Each Loan shall be made in compliance with, and subject to, the applicable Fund’s Prospectus and Regulation U and no portion of any proceeds of any Loan shall be used directly or indirectly in violation of any provision of any statute, regulation, order or restriction applicable to the Bank, any Borrower or any Fund.

7.    Addition of Borrowers and Funds. With the prior written consent of the Bank in its sole discretion and in any event no more than once per calendar quarter, any Borrower may request the addition to the terms of this Agreement of (a) one or more investment management companies registered under the Investment Company Act, with the same Investment Adviser as the Funds herein, as a Borrower hereunder or (b) any fund series of a Borrower. In no event will any such additional investment management company or fund series be added to the terms of this Agreement if such investment management company or fund series is advised or sub-advised by an affiliate of the Bank. The addition of any such investment management company or fund series shall be subject to consent by the Bank in its sole discretion, approval by the Board of trustees of the respective Borrowers, and completion of an appropriate amendment to this Agreement and such other documentation, and the collection of such fees or charges, as the Bank may require, including without limitation current prospectus and related information; corporate, trust or similar existence and authorization documentation; and appropriate legal opinions, in each case with respect to any proposed new Borrower or Fund, as the Bank may require.

8.    Commitment Fee. Each of the Borrowers, on behalf of its respective Funds, shall pay to the Bank its ratable portion (calculated in accordance with Section I.5(c) above) of commitment fee accruing at the rate of 0.20% per annum on the unused portion of the Committed Line Amount. Such commitment fee shall accrue from and including the date hereof to but excluding the Expiration Date. Accrued commitment fees payable by each of the Borrowers, on behalf of its respective Funds, hereunder shall be payable quarterly in arrears on the fifteenth day of each April, July, October and January for the immediately preceding calendar quarter and on the Expiration Date or any earlier date upon which the Committed Line hereunder may be terminated (including pursuant to Section II(4) hereof upon the occurrence of an Event of Default). The commitment fee provided for in this paragraph shall be calculated on the basis of a 360-day year for the actual number of days elapsed.

9.    Additional Costs; Capital Adequacy.

(a) If any new law, rule or regulation, or any change after the date hereof in the interpretation or administration of any applicable law, rule or regulation by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by the Bank (or its applicable lending office) with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency in connection therewith issued, promulgated or enacted after the date hereof shall:

(i) subject the Bank (or its applicable lending office) to any tax, duty or other charge with respect to the Loans, the Note or the Bank’s commitment hereunder, or shall change the basis of taxation of payments to the Bank (or its applicable lending office) of the principal of or interest on the Loans or any other amounts due under this Agreement or the Bank’s commitment hereunder, in each case, except for any tax on, or changes in the rate of tax on the overall net income of, or franchise taxes payable by, such Bank or its applicable lending office described in Section I(5)(b) above; or

(ii) impose, modify or deem applicable any reserve (including, without limitation, any such requirement imposed by the Board of Governors of the Federal Reserve System), special deposit, insurance assessment or similar requirement against assets of, deposits with or for the account of, or credit extended by, the Bank (or its applicable lending office) or shall impose on the Bank (or its applicable lending office) any other condition affecting the Loans, the Note or the Bank’s commitment hereunder; or

(iii) impose on the Bank any other conditions or requirements with respect to this Agreement, the other Loan Documents, the Loans or the Bank’s commitment hereunder;

and the result of any of the foregoing is to increase the cost to the Bank (or its applicable lending office) of making, funding, issuing, renewing, extending or maintaining any Loan or the Bank’s commitment hereunder, or to reduce the amount of any sum received or receivable by the Bank (or its applicable lending office) under this Agreement or under the Note with respect thereto, by an amount deemed by the Bank to be material, then, promptly upon demand by the Bank (and in any event within thirty (30) days after demand by the Bank) and delivery to the Borrowers of the certificate required by clause (c) of this Section I(9), each of the Borrowers, on behalf of its respective Funds, shall pay to the Bank its ratable portion (calculated in accordance with Section I(5)(c) above) of the additional amount or amounts as will compensate the Bank for such increased cost or reduction.

(b) If the Bank shall determine that any change after the date hereof in any existing applicable law, rule or regulation or any new law, rule or regulation regarding capital adequacy or liquidity, or any change therein, or any change after the date hereof in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or any new request or directive of general applicability regarding capital adequacy or liquidity (whether or not

January 28, 2015

having the force of law) of any such authority, central bank or comparable agency issued, promulgated or enacted after the date hereof, has or would have the effect of reducing the rate of return on capital of the Bank (or its parent corporation) as a consequence of the Bank’s obligations hereunder to a level below that which the Bank (or its parent corporation) could have achieved but for such law, change, request or directive (taking into consideration its policies with respect to capital adequacy and liquidity) by an amount deemed by the Bank to be material, then from time to time, promptly upon demand by the Bank (and in any event within thirty (30) days after demand by the Bank), each of the Borrowers, on behalf of its respective Funds, shall pay to the Bank its ratable portion (calculated in accordance with Section I(5)(c) above) of such additional amount or amounts as will compensate the Bank (or its parent corporation) for such reduction.

(c) The Bank will promptly notify the Borrowers of any event of which it has knowledge, occurring after the date hereof, which will entitle the Bank to compensation pursuant to this Section. A certificate of the Bank claiming compensation under this Section and setting forth in reasonable detail the additional amount or amounts to be paid to it hereunder and the calculations used in determining such additional amount or amounts shall be conclusive in the absence of manifest error. In determining such amount, the Bank may use any reasonable averaging and attribution methods.

(d) For the avoidance of doubt and notwithstanding anything herein to the contrary, for the purposes of this Section I(9), (i) the Dodd-Frank Wall Street Reform and Consumer Protection Act and all requests, rules, regulations, guidelines, interpretations or directives thereunder or issued in connection therewith (whether or not having the force of law) and (ii) all requests, rules, regulations, guidelines, interpretations or directives promulgated by the Bank for International Settlements, the Basel Committee on Banking Supervision (or any successor or similar authority) or the United States or foreign regulatory authorities (whether or not having the force of law), in each case for this clause (ii) pursuant to Basel III, shall in each case be deemed to be a change in law regardless of the date enacted, adopted, issued, promulgated or implemented.

II. General Loan Terms.

1. Covenants. Until all obligations of the Borrowers, on behalf of, their respective Funds with respect to the Committed Line have been paid in full and the Committed Line has been terminated, unless otherwise consented to in writing by the Bank, each of the Borrowers hereby covenants and agrees as follows for itself (where applicable) and on behalf of each of its respective Funds, but not as to any other Borrower or Funds:

(a) not at any time to permit (i) the aggregate amount of Total Liabilities of any Fund that are Senior Securities Representing Indebtedness to exceed the Applicable Percentage of the Adjusted Net Assets of such Fund or (ii) the aggregate amount of the Fund’s outstanding Indebtedness to otherwise exceed for the Maximum Amount applicable to such Fund at such time;

For value received, each of the undersigned hereby severally (and not jointly) promises to pay to STATE STREET BANK AND TRUST COMPANY (the “Bank”), or order, at the office of the Bank at One Lincoln Street, Boston Massachusetts 02111 in immediately available United States dollars, the principal amount of TWO HUNDRED MILLION DOLLARS ($200,000,000.00), or such lesser original principal amount as shall be outstanding hereunder and not have been prepaid as provided herein, together with interest thereon as provided below. Each Loan shall be payable upon the earliest to occur of (a) 60 calendar days following the date on which such Loan is made, (b) the Expiration Date, or (c) the date on which such Loan otherwise becomes due and payable under the terms of the Loan Agreement referred to below, whether following the occurrence of an Event of Default or otherwise. Interest on the unpaid principal amount outstanding hereunder shall be payable at the rates and at the times as set forth in the Loan Agreement and shall be computed as set forth in the Loan Agreement. Interest shall be computed on the basis of a 360-day year for the actual number of days elapsed, including holidays or other days on which the Bank is not open for the conduct of banking business.

All Loans hereunder and all payments on account of principal and interest hereof shall be recorded by the Bank. The entries on the records of the Bank (including any appearing on this Note), absent manifest error, shall govern and control as to amounts outstanding hereunder, provided that the failure by the Bank to make any such entry shall not affect the obligation of the undersigned to make payments of principal and interest on all Loans as provided herein and in the Loan Agreement.

Following the occurrence of a Default or an Event of Default with respect to any Fund, unpaid principal on any Loan to such Fund, and to the extent permitted by applicable law, unpaid interest on any Loan to such Fund, shall thereafter bear interest, compounded monthly and be payable on demand, until paid in full (after as well as before judgment) at a rate per annum equal to two percent (2%) above the rate otherwise applicable to such Loan under the Loan Agreement.

This Note is issued pursuant to, and entitled to the benefits of, and is subject to, the provisions of a certain letter agreement dated January 28, 2015 by and among the undersigned and the Bank (herein, as the same may from time to time be amended, restated, supplemented, modified or extended, referred to as the “Loan Agreement”), but neither this reference to the Loan Agreement nor any provision thereof shall affect or impair the absolute and unconditional obligation of the undersigned makers of this Note to pay the principal of and interest on this Note as herein provided. All terms not otherwise defined herein shall be used as defined in the Loan Agreement.

Any of the undersigned may at its option prepay all or any part of the principal of this Note subject to the terms of the Loan Agreement. Amounts prepaid may be reborrowed subject to the terms of the Loan Agreement.

Each of the undersigned makers and every endorser and guarantor hereof hereby waives presentment, demand, notice, protest and all other demands and notices in connection with the delivery, acceptance, performance, default or enforcement hereof and consents that this Note may be extended from time to time and that no such extension or other indulgence, and no substitution, release or surrender of collateral and no discharge or release of any other party primarily or secondarily liable hereon, shall discharge or otherwise affect the liability of any of the undersigned or any such endorser or guarantor. No delay or omission on the part of the Bank in exercising any right hereunder shall operate as a waiver of such right or of any other right hereunder, and a waiver of any such right on any one occasion shall not be construed as a bar to or waiver of any such right on any future occasion.

This instrument shall have the effect of an instrument executed under seal and shall be governed by and construed in accordance with the laws of The State of New York (without giving effect to any conflicts of laws provisions contained therein).

October 1, 2021

Introduction

This Code of Ethics (the “Code”) establishes rules of conduct for employees, officers, directors and trustees of Baron Investment Funds Trust and Baron Select Funds, registered investment companies, and their respective series (each, a “Baron Fund” and collectively, the “Baron Funds”), Baron Capital Group, Inc. (“BCG”), and its subsidiaries, Baron Capital, Inc. (“BCI”), the distributor of the Baron Funds, BAMCO, Inc. (“BAMCO”), a registered investment adviser that provides investment advisory services to the Baron Funds and sub-advisory services to unaffiliated registered investment companies, foreign investment companies and other pooled investment vehicles, and Baron Capital Management, Inc. (“BCM”), a registered investment adviser that provides investment advisory services to separately managed accounts, including wrap accounts, offshore funds and a private partnership (BAMCO and BCM, each, an “Adviser” and collectively, the “Advisers” and BCG, BCI, BAMCO and BCM, collectively, “Baron” or the “Firm”). In addition, certain provisions of the Code also apply to Immediate Family Member(s) living in the same household. The restrictions on personal investment transactions may also be applied to temporary personnel (i.e., interns, contractors, or consultants), whose tenure exceeds 90 days and/or who are deemed to have access to nonpublic systems. Capitalized terms not previously defined in the Code may be found in the Glossary of Terms at the end of this document

Statement of General Fiduciary Principles

The following general fiduciary principles will govern Personal Securities Transactions and the interpretation and administration of this Code:

• The interests of Clients must be placed first at all times;

• All Personal Securities Transactions must be conducted consistent with this Code and in such a manner as to avoid any actual or potential conflicts of interest or any abuse of an individual’s position of trust and responsibility; and

• Persons subject to the Code should not take inappropriate advantage of their positions.

1

This Code does not attempt to identify all possible conflicts of interest, and literal compliance with each of its specific provisions will not shield persons subject to the Code from liability for Personal Securities Transactions or other conduct that violates a fiduciary duty to Clients.

The Code reinforces the Baron Principles:

• We are committed to complying with both the letter and spirit of the laws, regulations, and ethical standards that govern our industry;

• Our actions must never be dictated by self-interest or perceived as such;

• If we treat our Clients ethically and with respect, and provide them with high quality services, we will be successful;

• We insist on honesty, integrity, and fair dealing;

• We maintain high ethical standards in dealing with our Clients, the companies in which we invest on their behalf, our community, our regulators, our competitors, and our co-workers; and

• Professionalism is critical to our business.

We are proud of our reputation for hard work, the quality of the individuals who work at our Firm, and the quality of the investment research they produce, and the asset management services they provide. Our most important assets are our employees and our reputation. Although our business would be adversely affected if we lost either, our reputation would be more difficult to regain. The provisions of the Code are designed to help us safeguard our reputation.

Baron is committed to fostering a culture of compliance and therefore requires employees to contact the Chief Compliance Officer (“CCO”), General Counsel, or President (the ”Designated Persons”) about any actual or suspected compliance matters. The CCO will receive reports on all violations of the Code reported to a Designated Person. Employees have the option of reporting compliance matters on a confidential basis by utilizing the Confidential Compliance Reporting email address, ComplianceReporting@Baronfunds.com. Retaliation against any employee for reporting compliance related issues is prohibited and cause for disciplinary action up to and including termination of employment.

If you have questions about any aspect of the Code, or if you have questions regarding application of the Code to a particular situation, contact one of the Designated Persons.

Prohibited Transactions and Other Restrictions on Personal Trading

Restrictions

Securities Issued by a Publicly Traded Company

• No Access Person may purchase Securities Issued by a Publicly Traded Company, including securities issued in an Initial Public Offering, options, warrants, and derivatives.

2

• An Access Person may sell Securities Issued by a Publicly Traded Company (i.e., those that were purchased prior to joining the Firm or prior to the institution of the Code) subject to the Pre-Clearance and Holding Period provisions below, provided that the Access Person first confirms, by consulting the appropriate Portfolio Managers, that such securities are not Covered Securities being considered for Purchase or Sale and indicates that such confirmation has been obtained in the “Comments” field in StarCompliance (“STAR”), the Firm’s automated system for administration of the Code.

• No Access Person may sell Securities Issued by a Publicly Traded Company short.

• No Research Analyst may recommend the purchase or sale of a Covered Security, to a Portfolio Manager without first disclosing his or her interest, if any, in the Covered Security to the Designated Persons. The disclosure should include the Research Analyst’s Beneficial Ownership, the potential impact that the recommended purchase or sale of a Covered Security may have on that Beneficial Ownership, and any other information that would be relevant in assessing whether such recommendation creates a conflict of interest.

• These restrictions do not apply to Independent Trustees or Independent Directors, except as set forth below.

Blackout Periods

A pre-clearance request will be denied if there has been a transaction by a Client of Baron within (15) calendar days. If a Client purchases a Covered Security within seven (7) calendar days after an Access Person purchases that security, or if a Client sells a Covered Security within seven (7) calendar days after an Access Person sells that security, the Client must receive the better price.

The Compliance Department will monitor trading activity for seven (7) calendar days following the pre-clearance approval date for conflicts of interests.

The total amount of the difference between the Access Person’s price and the Client’s price is calculated by multiplying the difference in price by the number of shares purchased or sold by the Access Person, not to exceed the number of shares purchased or sold by the Client. If the discrepancy is less than $250, the Designated Persons will decide how to resolve the situation.

Short Term Trading

The minimum holding period for Covered Securities is six (6) months. The holding period does not apply to Covered Securities owned by employees before they joined the Firm.

3

The holding period described above does not apply to transactions to close a legitimate hedge, provided that the underlying security being hedged has been held for the required holding period.

Prohibition on Initial Public Offerings (“IPOs”) and Short Sales

Access Persons may not participate in IPOs or effect short sales.

Private Placements

An Access Person may purchase securities in a private placement transaction (“Private Placements”) only if approval of the CCO has been obtained. This approval will be based upon a determination that the investment opportunity need not be reserved for clients, that the Access Person is not being offered the investment opportunity due to his or her employment with Baron, and other relevant factors on a case-by-case basis.

Investment personnel who have been approved to acquire securities in a private placement are required to disclose that investment when they are involved in any Baron Fund’s subsequent consideration of an investment or divestment in the issuer. In such circumstances, the investment company’s decision to purchase or sell securities of the issuer are subject to an independent review by investment personnel with no personal interest in the matter and at least one of the Designated Persons.

Because there is often no broker-dealer involved in a private placement, the employee must provide other evidence of the purchase or sale that is satisfactory to the CCO. The documentation must explain the circumstances surrounding the transaction, including the title of each security involved, the quantity of each security purchased or sold, the date of the transaction, and the price at which the transaction was executed.

Capital calls made pursuant to private investments that have already been approved do not require further pre-clearance.

Insider Trading

All Access Persons should pay particular attention to potential violations of insider trading laws. Insider trading is both unethical and illegal and would be cause for termination were it to occur. Employees are expected to familiarize themselves with the Insider Trading Policy adopted by Baron.

Exceptions to Code Restrictions

The Designated Persons may grant exemptions from the restrictions in this Code. The decision will be based on a determination that the transaction for which an exemption is requested would not result in a conflict with or violate any other policy embodied in this Code. Exceptions will likely be granted in the following cases:

4

1. The transaction would be very unlikely to affect a highly liquid market (‘de minimis exemption”);

2. The transaction is clearly not related economically to Covered Securities being considered for Purchase or Sale or Covered Securities Held or to be Acquired;

3. Special circumstances exist and granting an exception would not be inconsistent with the provisions of the Code.

Any exemption will be evidenced in writing and will be reported to the Board of Trustees of the Baron Funds and/or the Board of Directors of BCG, as necessary.

Outside Business Activities

From time to time, Baron employees are asked to serve as directors, advisory directors, trustees or officers of various corporations, charitable organizations and foundations (collectively, “Outside Organizations”). Other involvement with Outside Organizations may include part-time jobs, charitable work or voluntary commitments. Some of these outside activities may involve participation in, or knowledge of, proposed financial investments by the Outside Organization.

While there is no absolute prohibition on an employee participating in such activities with an Outside Organization, the proposed participation must comply with all applicable policies and procedures.

However, there may be circumstances in which it would not be in Baron’s best interests to allow an employee to participate in activities with an Outside Organization, even if the employee’s participation would not violate Baron’s policies and procedures. The initial consideration must be whether the activity will absorb so much of the employee’s time that it will affect his or her performance at Baron.

The most important consideration, however, is whether the outside activity will subject Baron and the employee to potential conflicts of interest. Baron’s business requires strict adherence to the highest ethical standards and the avoidance of an appearance of impropriety, conflicts of interest or the appearance of a conflict must be managed. It is impossible to anticipate every conflict of interest that may arise, but activities with Outside Organizations should be limited to those that either do not present or have the least potential of presenting conflicts of interest.

No Baron employee may be employed by, or accept compensation from, any other person as a result of any business activity, other than a passive investment, outside the scope of his or her relationship with the Firm, without the prior written approval from the Designated Persons.

Serving on Boards of Public Companies

No Access Person may serve on the board of directors of a Publicly Traded Company. This restriction does not apply to Independent Trustees or Independent Directors.

Policies on Personal Securities Transactions

Pre-Clearance Policy and Procedures

All Access Persons (other than Independent Trustees and Independent Directors who are not employees of the Firm) must pre-clear their Personal Securities Transactions in Covered Securities prior to execution, except as specifically exempted in subsequent sections of the Code.

Transactions in Covered Securities in which Access Persons have Beneficial Ownership must be pre-cleared and reported. This includes transactions in the following:

• Stocks;

• Preferred Stocks;

• Convertible Securities;

• ADRs and GDRs;

• Fixed Income Securities;

• Private Placements;

• Exchange Traded Funds;

• Exchange Traded Notes;

• Closed- End Funds;

• Shares issued by Unit Investment Trusts;

• Derivatives (including options, futures, forwards, etc.); and

• Limited partnerships and limited liability company interests.

Spouses and dependent children living in the Access Person’s household who make their own investment decisions are exempt from restrictions prohibiting purchases and sales of Securities Issued by Publicly Traded Companies, the pre-clearance requirements, the 6-month holding period, and the blackout periods. Compliance will review transactions in Covered Securities being considered for Purchase or Sale and Covered Securities Held or to be Acquired for activity that raises a question of impropriety.

All Personal Securities Transaction reporting and requests for pre-clearance must be processed through StarCompliance at: https://baronfunds.starcompliance.com/Auth/Login . The CCO or another Designated Person will evaluate and review each pre-clearance request and notification will be provided to employees through StarCompliance.

If an Access Person’s proposed transaction is not approved on the day it is submitted, it may not be executed. If it is not executed on the day approval is given, the approval lapses. Approvals are only valid for the day they are given. In both cases, the proposed transaction would need to be re-entered in StarCompliance for pre-clearance.

Reporting, but not pre-clearance, is required for non-volitional investment activity in the following:

6

• Transactions that result from corporate actions applicable to all similar security holders, such as splits, tender offers, mergers, stock dividends, etc.; or

• Purchases which are part of an automatic dividend reinvestment plan; or

• Purchases effected upon the exercise of rights issued by an issuer pro rata to all holders of a class of its securities, to the extent such rights were acquired from such issuer, and sales of such rights; and

• Gifts of shares in Covered Securities over which the Access Person has no control.

Reporting and Certification Requirements

All Access Persons’ Personal Securities Transactions and holdings reports will be reviewed by Compliance. The records and reports created or maintained pursuant to the Code are intended solely for internal use and are confidential unless required to be disclosed to a regulatory or governmental agency.

Initial Holdings Report

Within ten (10) calendar days of the start of employment, each Access Person must list all Baron Funds, Covered Accounts, and Covered Securities held at the time of hiring in which they have beneficial ownership. You are deemed to have beneficial ownership of securities held by members of your immediately family sharing the same household (e.g., your spouse and dependent children) or by certain partnerships, trusts, corporations, or other arrangements. Statement(s) must be current as of a date not more than 45 days prior to the Access Person’s employment start date. Within ten (10) calendar days of the start of employment, each Access Person must request that all broker-dealers or banks with which he or she has managed and/or brokerage accounts send duplicate confirmations and statements of their transactions in Covered Securities to the Compliance Department. If the Access Person requests, the Compliance Department will send a standard letter to the broker-dealer or bank in question, making a request on the Access Person’s behalf.

It remains the Access Person’s responsibility, however, to ensure that the duplicate statements and confirmations are provided.

Access Persons who fail to submit the report within ten (10) calendar days of their employment start date will be prohibited from engaging in any Personal Securities Transactions until such report is submitted and may be subject to other sanctions.

New Accounts

All Access Persons must receive written permission from the Compliance Department prior to opening any new managed accounts, brokerage accounts, or any other types of accounts that may hold Covered Securities in which they have beneficial ownership. You are deemed to have beneficial ownership of securities held by members of your immediately family sharing the same household (e.g., your spouse and dependent children) or by certain partnerships, trusts, corporations, or other arrangements. Unless the account has been reported, the Access Person is prohibited from engaging in Personal Securities Transactions in the account.

7

Managed Accounts

Personal Securities Transactions in Managed Accounts are excluded from the restrictions on purchasing Securities Issued by a Publicly Traded Company, as well pre-clearance, holding period, restricted period and quarterly transaction reporting. Each Managed Account (not the holdings) must be included in the Annual Holdings Report. On a quarterly basis, employees will need to certify that they do not have any trading discretion in any Managed Account, will not attempt to exercise any trading discretion in the future, and will not discuss any information or recommendation regarding any Covered Security with the person or persons trading discretion over the account or provide an explanation for why they cannot make such a certification. Employees also must inform the Compliance Department of any changes to their Managed Accounts (e.g., a change to the trading discretion over the account).

Quarterly Transaction Reports

Within twenty (20) days of the end of each calendar quarter, each Access Person must submit a quarterly transaction report indicating all Personal Securities Transactions in Covered Securities made during the previous quarter.

Annual Holdings Report

On an annual basis within 30 days after December 31st of each year and/or at any other time as requested by the Firm, all Access Persons will report through StarCompliance all holdings of Covered Securities and Baron Funds which such Access Person has direct or indirect Beneficial Ownership. You are deemed to have beneficial ownership of securities held by members of your immediately family sharing the same household (e.g., your spouse and dependent children) or by certain partnerships, trusts, corporations or other arrangements.

Certification Requirements

Access Persons are required to complete a Code certification upon commencement of their employment with Baron, and annually thereafter, to acknowledge and certify that they have received, reviewed, understand and will comply with the Code. In addition, all material amendments to, or any new interpretations of, the Code will be conveyed to Access Persons and require their acknowledgement of receipt and understanding. In addition, all Access Persons complete an annual compliance questionnaire, designed to identify potential conflicts of interest.

Gifts

During each calendar year, all Access Persons will report all gifts and entertainment through StarCompliance. No Access Person may accept any gift or other item of more than $100 in value from any person or entity that does business with the Firm without pre-approval of the CCO. Meals and

8

entertainment that are attended by both the Access Person and a representative of the company providing the meal or entertainment are not subject to the $100 limit, however, meals and entertainment may neither be so frequent nor so extensive as to raise a question of impropriety. This restriction does not apply to Independent Trustees or Independent Directors. The Firm’s Policy Regarding Receipt of Goods and Services provides more details.

Sanctions

Depending on the severity of the infraction, Access Persons may be subject to certain sanctions for violating the Code. Sanctions may include, verbal or written warnings, letters of reprimand, suspension of personal trading activity, disgorgement and forfeiture of profits, and/or suspension or termination of employment. Material violations will be escalated to the General Counsel and subsequently reported to the Board of Trustees of the Baron Funds and or the Board of Directors of BCG, as necessary.

Communications with Independent Trustees and Independent Directors

As a regular business practice, we attempt to keep Independent Trustees and Independent Directors informed with respect to the Firm’s investment activities through reports and other information provided to them in connection with board meetings and other events.

Independent Trustees and Independent Directors do not have ongoing day to day involvement with the Baron Funds or their Adviser. Accordingly, Independent Trustees and Independent Directors are exempt from the Restrictions set forth in the Code, unless the Independent Trustee or Independent Director executed a Personal Securities Transaction involving a security about which he or she received non-public information in the course of fulfilling his or her official duties on the Fund or Firm Board indicating that such security was a Covered Security being considered for Purchase or Sale or a Covered Security Held or to be Acquired within a 15 day period of the transaction.

As a general matter, the Adviser does not provide the Independent Trustees or Independent Directors non-public information about Covered Securities being considered for Purchase or Sale or Covered Securities Held or to be acquired within 15 days of such transaction. However, in order to assist the Independent Trustees and Independent Directors in meeting their obligations pursuant to the Code, the Adviser will notify them whenever such non-public information is discussed at a meeting or in materials provided for a meeting.

Investments, Risks, and Performance Principal Investment Strategies of the Fund

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a diversified fund that invests for the long term primarily in equity securities in the form of common stock of U.S. mid-sized growth companies. BAMCO, Inc. (“BAMCO” or the “Adviser”) defines mid-sized companies as those, at the time of purchase, with market capitalizations above $2.5 billion or the smallest market cap stock in the Russell Midcap Growth Index at reconstitution, whichever is larger, and below 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. Because of its long-term approach, the Fund could have a significant percentage of its assets invested in securities that have appreciated beyond their market capitalizations at the time of the Fund’s investment.

Risk [Heading]

rr_RiskHeading

Principal Risks of Investing in the Fund

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

General Stock Market.  Fund losses may be incurred due to declines in one or more markets in which Fund investments are made. 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 caused, among other reasons, by increased inflation, or tightening monetary policy or interest rate increases by the US Federal Reserve or similar international bodies, and reduced liquidity in financial markets may negatively affect many issuers, which could have an adverse effect on your Fund investment. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers worldwide. As a result, local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions or other events could have a significant negative impact on global economic and market conditions. The coronavirus disease 2019 (COVID-19) global pandemic and the aggressive responses taken by many governments or voluntarily imposed by private parties, including closing borders, restricting travel and imposing prolonged quarantines or similar restrictions, as well as the closure of, or operational 

changes to, many retail and other businesses, have had negative impacts, and in many cases severe negative impacts, on markets worldwide. It is not known how long such impacts, or any future impacts of other significant events described above, will or would last, but there could be a prolonged period of global economic slowdown, which may impact your Fund investment. 

Growth Investing.  Growth stocks can react differently to issuer, political, market and economic developments than the market as a whole and other types of stocks. 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. 

Mid-Sized Companies.  The Adviser believes there is more potential for capital appreciation in mid-sized companies, but there also may be more risk. Securities of 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 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. Mid-sized companies rely more on the skills of management and on their continued tenure. Investing in 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. 

Technology.  Technology companies, including internet-related and information technology companies, as well as companies propelled by new technologies, may present the risk of rapid change and product obsolescence, and their successes may be difficult to predict for the long term. Some technology companies may be newly formed and have limited operating history and experience. Technology companies may also be adversely affected by changes in governmental policies, competitive pressures and changing demand. The securities of these companies may also experience significant price movements caused by disproportionate investor optimism or pessimism, with little or no basis in the companies’ fundamentals or economic conditions.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes for Fund shareholders. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the example, affect the Fund’s performance.

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same.

Strategy [Heading]

rr_StrategyHeading

Investments, Risks, and Performance Principal Investment Strategies of the Fund

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a diversified fund that invests for the long term primarily in equity securities in the form of common stock of U.S. small-sized growth companies. BAMCO, Inc. (“BAMCO” or the “Adviser”) defines small-sized companies as those, at the time of purchase, with market capitalizations up to the largest market cap stock in the Russell 2000 Growth Index at reconstitution, or companies with market capitalizations up to $2.5 billion, whichever is larger. The Adviser seeks to invest in businesses it believes have significant opportunities for growth, sustainable competitive advantages, exceptional management, and an attractive valuation. Because of its long-term approach, the Fund could have a significant percentage of its assets invested in securities that have appreciated beyond their market capitalizations at the time of the Fund’s investment.

Risk [Heading]

rr_RiskHeading

Principal Risks of Investing in the Fund

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

General Stock Market.  Fund losses may be incurred due to declines in one or more markets in which Fund investments are made. 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 caused, among other reasons, by increased inflation, or tightening monetary policy or interest rate increases by the US Federal Reserve or similar international bodies, and reduced liquidity in financial markets may negatively affect many issuers, which could have an adverse effect on your Fund investment. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers worldwide. As a result, local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions or other events could have a significant negative impact on global economic and market conditions. The coronavirus disease 2019 (COVID-19) global pandemic and the aggressive responses taken by many governments or voluntarily imposed by private parties, including closing borders, restricting travel and imposing 

prolonged quarantines or similar restrictions, as well as the closure of, or operational changes to, many retail and other businesses, have had negative impacts, and in many cases severe negative impacts, on markets worldwide. It is not known how long such impacts, or any future impacts of other significant events described above, will or would last, but there could be a prolonged period of global economic slowdown, which may impact your Fund investment. 

Growth Investing.  Growth stocks can react differently to issuer, political, market and economic developments than the market as a whole and other types of stocks. 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. 

Small-Sized Companies.  The Adviser believes there is more potential for capital appreciation in small-sized companies, but there also may be more risk. Securities of small-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-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-sized companies rely more on the skills of management and on their continued tenure. Investing in small-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.

In addition, turbulence caused, among other reasons, by increased inflation, or tightening monetary policy or interest rate increases by the US Federal Reserve or similar international bodies, and reduced liquidity in financial markets may negatively affect many issuers, which could have an adverse effect on your Fund investment. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers worldwide. As a result, local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions or other events could have a significant negative impact on global economic and market conditions. The coronavirus disease 2019 (COVID-19) global pandemic and the aggressive responses taken by many governments or voluntarily imposed by private parties, including closing borders, restricting travel and imposing 

prolonged quarantines or similar restrictions, as well as the closure of, or operational changes to, many retail and other businesses, have had negative impacts, and in many cases severe negative impacts, on markets worldwide. It is not known how long such impacts, or any future impacts of other significant events described above, will or would last, but there could be a prolonged period of global economic slowdown, which may impact your Fund investment. 

Growth Investing.  Growth stocks can react differently to issuer, political, market and economic developments than the market as a whole and other types of stocks. 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. 

Small-Sized Companies.  The Adviser believes there is more potential for capital appreciation in small-sized companies, but there also may be more risk. Securities of small-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‑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-sized companies rely more on the skills of management and on their continued tenure. Investing in small-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. 

Special Situations.  The Funds may invest in “special situations.” A special situation arises when, in the opinion of the Adviser, the securities of a company will be recognized and appreciate in value due to a specific anticipated development at that company. Such developments might include a new product, a management change, an acquisition or a technological advancement. The risk of investing in special situations is that the anticipated development does not occur or its impact is not what the Adviser expected. 

Technology.  Technology companies, including internet-related and information technology companies, as well as companies propelled by new technologies, may present the risk of rapid change and product obsolescence, and their successes may be difficult to predict for the long term. Some technology companies may be newly formed and have limited operating history and experience. Technology companies may also be adversely affected by changes in governmental policies, competitive pressures and changing demand. The securities of these companies may also experience significant price movements caused by disproportionate investor optimism or pessimism, with little or no basis in the companies’ fundamentals or economic conditions.

Risk [Heading]

rr_RiskHeading

Principal Risks of Investing in the Fund

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

General Stock Market.  Fund losses may be incurred due to declines in one or more markets in which Fund investments are made. 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 caused, among other reasons, by increased inflation, or tightening monetary policy or interest rate increases by the US Federal Reserve or similar international bodies, and reduced liquidity in financial markets may negatively affect many issuers, which could have an adverse effect on your Fund investment. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers worldwide. As a result, local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions or other events could have a significant negative impact on global economic and market conditions. The coronavirus disease 2019 (COVID-19) global pandemic and the aggressive responses taken by many governments or voluntarily imposed by private parties, including closing borders, restricting travel and imposing prolonged quarantines or similar restrictions, as well as the closure of, or operational changes to, many retail and other businesses, have had negative impacts, and in many cases severe negative impacts, on markets worldwide. It is not known how long such impacts, or any future impacts of other significant events described above, will 

or would last, but there could be a prolonged period of global economic slowdown, which may impact your Fund investment. 

Growth Investing.  Growth stocks can react differently to issuer, political, market and economic developments than the market as a whole and other types of stocks. 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. 

Small- and Mid-Sized Companies.  The Adviser believes there is more potential for capital appreciation in small- and mid-sized companies, but there also may be more risk. 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. 

Technology.  Technology companies, including internet-related and information technology companies, as well as companies propelled by new technologies, may present the risk of rapid change and product obsolescence, and their successes may be difficult to predict for the long term. Some technology companies may be newly formed and have limited operating history and experience. Technology companies may also be adversely affected by changes in governmental policies, competitive pressures and changing demand. The securities of these companies may also experience significant price movements caused by disproportionate investor optimism or pessimism, with little or no basis in the companies’ fundamentals or economic conditions.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes for Fund shareholders. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the example, affect the Fund’s performance. During the most recent fiscal year ended September 30, 2021, the Fund’s portfolio turnover rate was 15.87% of the average value of its portfolio.

Investments, Risks, and Performance Principal Investment Strategies of the Fund

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a diversified fund that invests primarily in equity securities in the form of common stock of U.S. large-sized growth companies. The Adviser defines large‑sized companies as those, at the time of purchase, with market capitalizations no smaller than the top 85^th percentile by total market capitalization of the Russell 1000 Growth Index at June 30, or companies with market capitalizations above $10 billion, whichever is smaller. The Adviser seeks to invest in businesses it believes have significant opportunities for growth, sustainable competitive advantages, exceptional management, and an attractive valuation.

Risk [Heading]

rr_RiskHeading

Principal Risks of Investing in the Fund

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

General Stock Market.  Fund losses may be incurred due to declines in one or more markets in which Fund investments are made. 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 caused, among other reasons, by increased inflation, or tightening monetary policy or interest rate increases by the US Federal Reserve or similar international bodies, and reduced liquidity in financial markets may negatively affect many issuers, which could have an adverse effect on your Fund investment. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market 

may adversely impact issuers worldwide. As a result, local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions or other events could have a significant negative impact on global economic and market conditions. The coronavirus disease 2019 (COVID-19) global pandemic and the aggressive responses taken by many governments or voluntarily imposed by private parties, including closing borders, restricting travel and imposing prolonged quarantines or similar restrictions, as well as the closure of, or operational changes to, many retail and other businesses, have had negative impacts, and in many cases severe negative impacts, on markets worldwide. It is not known how long such impacts, or any future impacts of other significant events described above, will or would last, but there could be a prolonged period of global economic slowdown, which may impact your Fund investment. 

Growth Investing.  Growth stocks can react differently to issuer, political, market and economic developments than the market as a whole and other types of stocks. 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. 

Large-Cap Companies.  Because the Fund invests primarily in large-cap company securities, it may underperform other funds during periods when the Fund’s securities are out of favor. 

Technology.  Technology companies, including internet-related and information technology companies, as well as companies propelled by new technologies, may present the risk of rapid change and product obsolescence, and their successes may be difficult to predict for the long term. Some technology companies may be newly formed and have limited operating history and experience. Technology companies may also be adversely affected by changes in governmental policies, competitive pressures and changing demand. The securities of these companies may also experience significant price movements caused by disproportionate investor optimism or pessimism, with little or no basis in the companies’ fundamentals or economic conditions. 

Consumer Discretionary Sector Risk.  The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers’ disposable income, consumer preferences, social trends and marketing campaigns.

Investments, Risks, and Performance Principal Investment Strategies of the Fund

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a diversified fund that invests for the long term primarily in equity securities in the form of common stock of U.S. small-sized growth companies. The Adviser defines small-sized companies as those, at the time of purchase, with market capitalizations up to the largest market cap stock in the Russell 2000 Growth Index at reconstitution, or companies with market capitalizations up to $2.5 billion, whichever is larger. The Adviser seeks to invest in businesses it believes have significant opportunities for growth, sustainable competitive advantages, exceptional management, and an attractive valuation. Because of its long-term approach, the Fund could have a significant percentage of its assets invested in securities that have appreciated beyond their market capitalizations at the time of the Fund’s investment.

Risk [Heading]

rr_RiskHeading

Principal Risks of Investing in the Fund

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

General Stock Market.  Fund losses may be incurred due to declines in one or more markets in which Fund investments are made. 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 caused, among other reasons, by increased inflation, or tightening monetary policy or interest rate increases by the US Federal Reserve or similar international bodies, and reduced liquidity in financial markets may negatively affect many issuers, which could have an adverse effect on your Fund investment. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers worldwide. As a result, local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions or other events could have a significant negative impact on global economic and market conditions. The coronavirus disease 2019 (COVID-19) global pandemic and the aggressive responses taken by many governments or voluntarily imposed by private parties, including closing borders, restricting travel and imposing prolonged quarantines or similar restrictions, as well as the closure of, or operational changes to, many retail and other businesses, have had negative impacts, and in many cases severe negative impacts, on markets worldwide. It is not known how long such impacts, or any future impacts of other significant events described above, will 

or would last, but there could be a prolonged period of global economic slowdown, which may impact your Fund investment. 

Growth Investing.  Growth stocks can react differently to issuer, political, market and economic developments than the market as a whole and other types of stocks. 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. 

Small-Sized Companies.  The Adviser believes there is more potential for capital appreciation in small-sized companies, but there also may be more risk. Securities of small-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-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-sized companies rely more on the skills of management and on their continued tenure. Investing in small-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. 

Special Situations.  The Funds may invest in “special situations.” A special situation arises when, in the opinion of the Adviser, the securities of a company will be recognized and appreciate in value due to a specific anticipated development at that company. Such developments might include a new product, a management change, an acquisition or a technological advancement. The risk of investing in special situations is that the anticipated development does not occur or its impact is not what the Adviser expected. 

Health Care Sector Risk.  Investments in health care companies are subject to a number of risks, including the adverse impact of legislative actions and government regulations. 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’s transition from development to production, or erratic revenue patterns. The stock prices of these companies are very volatile, particularly when their products are up for regulatory approval and/or under regulatory scrutiny.

Portfolio Turnover.

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes for Fund shareholders. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the example, affect the Fund’s performance. During the most recent fiscal year ended September 30, 2021, the Fund’s portfolio turnover rate was 10.58% of the average value of its portfolio.

Example

Expense Example Narrative [Text Block]

rr_ExpenseExampleNarrativeTextBlock

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a

5% return each year and that the Fund’s operating expenses remain the same, giving effect to the expense reimbursement agreement described above. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading]

rr_StrategyHeading

Investments, Risks, and Performance Principal Investment Strategies of the Fund

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is a diversified fund that invests primarily in equity securities in the form of common stock of U.S. large‑sized companies. The Adviser defines large‑sized companies as those, at the time of purchase, with market capitalizations no smaller than the top 90^th percentile by total market capitalization of the S&P 500 Index at June 30, or companies with market capitalizations above $10 billion, whichever is smaller. The Adviser seeks to invest primarily in what it believes are unique, well-managed, competitively advantaged businesses that generate significant excess free cash flow that is consistently returned to shareholders in the form of stock buybacks and/or dividends.

Risk [Heading]

rr_RiskHeading

Principal Risks of Investing in the Fund

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

General Stock Market.  Fund losses may be incurred due to declines in one or more markets in which Fund investments are made. 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 caused, among other reasons, by increased inflation, or tightening monetary policy or interest rate increases by the US Federal Reserve or similar international bodies, and reduced liquidity in financial markets may negatively affect many issuers, which could have an adverse effect on 

your Fund investment. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers worldwide. As a result, local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions or other events could have a significant negative impact on global economic and market conditions. The coronavirus disease 2019 (COVID-19) global pandemic and the aggressive responses taken by many governments or voluntarily imposed by private parties, including closing borders, restricting travel and imposing prolonged quarantines or similar restrictions, as well as the closure of, or operational changes to, many retail and other businesses, have had negative impacts, and in many cases severe negative impacts, on markets worldwide. It is not known how long such impacts, or any future impacts of other significant events described above, will or would last, but there could be a prolonged period of global economic slowdown, which may impact your Fund investment. 

Large‑Cap Companies.  Because the Fund invests primarily in large‑cap company securities, it may underperform other funds during periods when the Fund’s securities are out of favor.
