Investment Goal

The investment goal of Baron Asset Fund (the “Fund”) is capital appreciation through long-term investments primarily in securities of medium-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.

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

Based on fiscal year ended September 30, 2010.

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. 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	$	134	$	418	$	723	$	1,590
Institutional Shares	$	108	$	337	$	585	$	1,294

Fund Operating Expenses or in the example, affect the Fund’s performance. During the most recent fiscal year ended September 30, 2010, the Fund’s portfolio turnover rate was 13.04% of the average value of its portfolio.

Investments, Risks, and Performance

Principal Investment Strategies of the Fund

The Fund invests for the long term primarily in equity securities in the form of common stock of medium-sized growth companies with market capitalizations of between $1.5 billion and $12 billion at the time of purchase selected for their capital appreciation potential. The Fund purchases securities in businesses that BAMCO, Inc. (“BAMCO” or “the Adviser”) believes could double in value in four years. The Adviser selects securities that it believes have favorable price-to-value characteristics, are well managed, have significant long term growth prospects and have significant barriers to competition. Of course, there can be no guarantee that the Adviser will be successful in achieving the Fund’s investment goals. Because of its long-term approach, the Fund could have a significant percentage of its assets invested in securities that have appreciated beyond their original market cap ranges.

Principal Risks of Investing in the Fund

General Stock Market. Investing in the stock market is risky because securities fluctuate in value. These fluctuations may be due to political, economic or general market circumstances. Other factors may affect a single company or industry but not the broader market. Because the values of securities fluctuate, when you sell your investment in the Fund, you may receive less money than you originally invested. Current and future portfolio holdings in the Fund are subject to risk.

Medium-Sized Companies. The Adviser believes there is more potential for capital appreciation in medium-sized companies, but there also may be more risk. Securities of medium-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 medium-sized companies may fluctuate in price more widely than the stock market generally, and they may be more difficult to sell during market downturns. Medium-sized companies rely more on the skills of management and on their continued tenure. Investing in medium-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.

compared to other types of stocks. As a result, growth stocks tend to be sensitive to changes in their earnings and more volatile than other types of stocks.

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 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 12/31/10)

The table below 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, 2010. The table also shows the average annual returns of the Fund’s Institutional 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. In some instances, the “Return after taxes on distributions and sale of Fund shares” is greater than the “Return before taxes” because you are assumed to be able to use the capital loss on the sale of Fund shares to offset other taxable gains.

Baron Asset Fund

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.

Performance prior to May 29, 2009 is based on the performance of the Retail Shares which have a distribution fee. The Institutional Shares do not have a distribution fee. If the annual returns prior to May 29, 2009 did not reflect this fee, the returns would be higher.

Investments, Risks, and Performance

Principal Investment Strategies of the Fund

The Fund invests for the long term primarily in equity securities in the form of common stock of small-sized growth companies with market capitalizations of under $2.5 billion at the time of purchase selected for their capital appreciation potential. The Fund purchases securities in businesses that BAMCO, Inc. (“BAMCO” or “the Adviser”) believes could double in value in four or five years, and then hopefully, double again in the next four or five years. The Adviser selects securities that it believes have favorable price-to-value characteristics, are well managed, have significant long term growth prospects and have significant barriers to competition. Of course, there can be no guarantee that the Adviser will be successful in achieving the Fund’s investment goals. Because of its long-term approach, the Fund could have a significant percentage of its assets invested in securities that have appreciated beyond their original market cap ranges.

Principal Risks of Investing in the Fund

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.

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.

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

Investments, Risks, and Performance

Principal Investment Strategies of the Fund

The Fund invests 80% of its net assets in equity securities in the form of common stock of small-sized growth companies with market capitalizations of less than $2.5 billion at the time of purchase selected for their capital appreciation potential. The Fund seeks to purchase securities that BAMCO, Inc. (“BAMCO” or “the Adviser”) expects could increase in value 50% within two years. The Adviser selects securities that it believes have favorable price-to-value characteristics, are well managed, have significant long term growth prospects and have significant barriers to competition. Of course, there can be no guarantee that the Adviser will be successful in achieving the Fund’s investment goals. Because of its long-term approach, the Fund could have a significant percentage of its assets invested in securities that have appreciated beyond their original market cap ranges.

Principal Risks of Investing in the Fund

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,



		1-800-99BARON		16


		Baron Small Cap Fund

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.

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, growth stocks tend to be sensitive to changes in their earnings and more volatile than other types of stocks.

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:

Investments, Risks, and Performance

Principal Investment Strategies of the Fund

The Fund invests primarily in equity securities in the form of common stock of high growth businesses of all market capitalizations selected for their capital appreciation potential. The Adviser may invest in companies in any sector or industry that it believes will benefit from innovations and advances in technology. The Fund seeks to purchase securities that the Adviser expects could increase in value 100% within four years. The Adviser selects securities that it believes have favorable price-to-value characteristics, are well managed, have significant long term growth prospects and have significant barriers to competition. Of course, there can be no guarantee that the Adviser will be successful in achieving the Fund’s investment goals.

Principal Risks of Investing in the Fund

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.

		Baron Opportunity Fund

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

Average Annual Total Returns (for periods ended 12/31/10)

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. In some instances, the “Return after taxes on distributions and sale of Fund shares” is greater than the “Return before taxes” because you are assumed to be able to use the capital loss on the sale of Fund shares to offset other taxable gains.

The Russell MidCap Growth has replaced the NASDAQ Composite as the primary broad-based index for the Fund because the Adviser believes that the Russell MidCap Growth is more representative of the Fund’s investment strategy. The NASDAQ Composite remains in the table above for comparison purposes.

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

The investment policy of the Funds relating to the types of securities in which the Funds’ assets must be primarily invested may be changed by the Board of Trustees (the “Board”) of the Funds without shareholder approval upon at least 60 days’ notice.

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



		1-800-99BARON		32


Information about the Funds		Baron Funds^®

Baron Small Cap Fund, and up to 25% of the respective total assets of Baron Opportunity Fund and Baron Fifth Avenue Growth 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, developing countries which are countries that from time to time comprise the MSCI Emerging Markets (EM) Index, and frontier countries which are countries that from time to time comprise the MSCI Frontier Markets (FM) Index.

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.

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.



		33		www.BaronFunds.com


Baron Funds^®			Information about the Funds

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, Baron Opportunity Fund and Baron Fifth Avenue Growth 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.

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 accompanying 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.

In making investment decisions for the Funds the Adviser seeks:

securities that the Adviser believes have favorable price-to-value characteristics based on the Adviser’s assessment of their businesses’ prospects for future growth and profitability; and

businesses that the Adviser believes are well managed, have significant long-term growth prospects and have significant barriers to competition.

The Adviser’s research process includes visits and interviews with company managements, their major competitors and often their customers. It also studies industry data, statistics and trends. The Adviser looks for companies that it believes have the ability to grow substantially within a four or five-year period. The Adviser looks for companies that it believes have special business niches that offer favorable business opportunities and sustainable barriers to competition. It also seeks companies that it believes have strong management capabilities, good employee morale and favorable reputations. The Adviser invests without regard for market trends. It instead focuses on long-lasting “mega-trend” opportunities presented by individual investments. It also studies companies’ financial strength and profitability.

The Funds purchase stocks that the Adviser believes are undervalued relative to their businesses’ long-term growth prospects, future cash flows and asset values. The



		1-800-99BARON		34


Information about the Funds		Baron Funds^®

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 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 six-month period (Please see the “Policies Regarding Frequent Purchases and Redemptions of Fund Shares” section on pages 48-50 of this prospectus).

Additional Investment Risks

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.

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’ net asset values. 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



		35		www.BaronFunds.com


Baron Funds^®			Information about the Funds

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.

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 magnitude of these fluctuations will be greater when the maturity of the debt securities is longer.

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.

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.

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



		1-800-99BARON		36


Information about the Funds		Baron Funds^®

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 is not possible to effectively hedge the currency risks of many developing countries.

Geographic Risk. Funds that are less diversified across geographic regions, countries, industries, or individual companies are generally riskier than more diversified funds. 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.

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, 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 net asset values. As a result, net asset values may be significantly affected on days when shareholders cannot make transactions.

Developing Countries. The Funds’ investments in developing countries, which include countries in the MSCI Emerging Markets (EM) Index, are subject to all of the risks of foreign 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 frontier countries, which include countries in the MSCI Frontier Markets (FM) Index.

Risks of Emphasizing a Region, Sector, or Industry. If a Fund has invested a higher percentage of its total assets in a particular region, sector or industry, changes affecting that region, sector or industry may have a significant impact on the performance of that Fund’s overall portfolio.

Taxes. Each of the Funds intends to elect to be treated and to qualify each year as a “regulated investment company” under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”). To maintain its qualification for federal income tax purposes as a regulated investment company under the Code, each Fund must meet certain source-of-income, asset diversification and annual distribution



		37		www.BaronFunds.com


Baron Funds^®			Information about the Funds

requirements, as discussed in detail in the “U.S. Federal Income Taxation” section on pages 52-54 of this prospectus. If for any taxable year the Funds fail to qualify for the special federal income tax treatment afforded to regulated investment companies, all of the Funds’ taxable income will be subject to federal income tax at regular corporate rates (without any deduction for distributions to the Funds’ shareholders) and the Funds’ income available for distribution would be reduced (please see the “U.S. Federal Income Taxation” section on pages 52-54 of this prospectus, and the “Taxation of the Funds” section on pages 34-40 in the SAI).

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 may involve more risk. Baron Asset Fund may invest up to 10%, and Baron Growth Fund, Baron Small Cap Fund, Baron Opportunity Fund and Baron Fifth Avenue Growth Fund may invest up to 15%, of their respective net assets in securities that are illiquid. An illiquid security is one that cannot be disposed of in the ordinary course of business within seven days. Such investments may include private equity securities, PIPE securities and other restricted securities.

Share Classes

The Funds offer two classes of shares, Retail Shares and Institutional 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. 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 through the Baron Funds without paying a sales charge or any other additional fees. Employees and Trustees of the Baron Funds are not subject to the eligibility requirements for Institutional Shares. For more information, please see the “How to Purchase Shares” section on pages 42-44 of this prospectus. Baron Funds reserve the right, without prior notice, to change the eligibility requirements of its share classes, including the types of clients who are eligible to purchase each share class.

How Your Shares are Priced

The purchase or sale price for your Shares is the Funds’ net asset value per share (“NAV”), which is generally calculated as of the close of regular trading on the New York Stock Exchange (“Exchange”) (usually 4 p.m. Eastern Time (“E.T.”)) on each day the Exchange is 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 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 NAV will not be calculated on days when the Exchange is closed for trading. 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.

Funds’ investments traded on any national stock exchange are valued based on their last sale prices. For securities traded on NASDAQ, the Funds use the NASDAQ Official Closing Price. 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 closes but before the Funds are priced that materially affects the value of a security, the securities 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 executives, and the Committee provides a report to the Board every quarter. Factors the Committee considers when valuing a security include whether a current price is stale, there is recent news, the security is thinly traded, transactions are infrequent and 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. The Funds may change the time at which orders are priced if the Exchange closes at a different time or an emergency exists. U.S. Government obligations and other debt instruments having sixty days or less remaining until maturity are stated at amortized cost. Debt instruments having a greater remaining maturity will be valued on the basis of prices obtained from a pricing service approved by the Board or at the mean of the bid and ask prices from a dealer maintaining an active market in that security.

Non-U.S. equity securities are valued on the basis of their most recent closing market prices and translated into U.S. dollars at 4 p.m. E.T., except under the circumstances described below. Most foreign markets close before 4 p.m. E.T. For securities primarily traded in the Far East, for example, the most recent closing prices may be as much as 15 hours old at 4 p.m. E.T. If the Adviser determines that developments between the



		41		www.BaronFunds.com


Baron Funds^®		Information about your Investment

close of the foreign market and 4 p.m. E.T. may, in its judgment, materially affect the value of some or all of a Funds’ non-U.S. securities, the Adviser will adjust the previous closing prices to reflect what it believes to be the fair value of the securities as of 4 p.m. E.T. In deciding whether to make these adjustments, the Adviser reviews a variety of factors, including developments in foreign markets, the performance of U.S. securities markets and the performance of instruments trading in U.S. markets that represent non-U.S. securities and baskets of non-U.S. securities. 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 uses outside pricing services to provide it with closing market prices and information used for adjusting those prices. The Adviser cannot predict how often it will use closing prices and how often it will adjust those prices.

How to Purchase Shares

You may purchase shares of the Funds directly without paying a sales charge. Please use the Funds’ “Regular Account Application” form to open an account. Special applications are available to open individual retirement accounts, such as Traditional, Roth, SEP or Simple IRAs (collectively “IRAs” or individually an “IRA”) and Coverdell accounts. All applications can be found at www.BaronFunds.com/applications. Please complete the application form in its entirety. If you do not provide all the information requested, your application will be returned to you and your investment will not be established.

The Funds offer two classes of shares, Retail Shares and Institutional Shares, which differ only in their ongoing fees and eligibility requirements. The minimum initial investment for the Retail Shares is $2,000 per Fund, unless you choose to invest through the Baron Automatic Investment Plan (please see the “Baron Automatic Investment Plan” section on page 45 of this prospectus). The minimum initial investment for Institutional Shares is $1,000,000 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 through the Baron Funds without paying a sales charge or any other additional fees. Employees and Trustees of the Baron Funds are not subject to the eligibility requirements for Institutional Shares.

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



		1-800-99BARON		42


Information about your Investment		Baron Funds^®

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 51-52 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 48-50 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. 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 a U.S. taxpayer identification number may be permitted to invest in the Funds if the Adviser determines that the broker-dealer through which the foreign investor intends to invest has sufficient anti-money laundering policies and procedures in place.

You 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, 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.

can obtain a signature guarantee from most securities firms or banks, but not from a notary public.

Through Brokers, Dealers or Other Financial Institutions

You may purchase shares of the Funds through a broker, dealer or other financial intermediary that may charge a transaction fee. If you purchase the 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, your redemption request may not be sent to you until the purchase check has cleared your bank, which generally occurs within fifteen calendar days.

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.

A signature guarantee is required for redemptions of more than $50,000 per Fund in any quarter (please see the “Special Information About Redemptions” section on pages 47-48 of this prospectus). Normally, within seven days after receipt of a redemption request by the Transfer Agent in the proper form, the Fund will mail you the proceeds.

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 in any quarter is $50,000 per



		1-800-99BARON		46


Information about your Investment		Baron Funds^®

Fund. 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; (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 signature guaranteed letter of instruction. Please include your account number.

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.

By Broker, Dealer or Other Financial Intermediaries

Accounts may redeem Fund shares held by a broker, dealer or other financial intermediary that may charge you a fee. The Funds may have special redemption procedures with certain brokers, dealers or other financial intermediaries.

Special Information about Redemptions

If the amount to be redeemed is greater than $50,000 per Fund, all of the signatures on a redemption request must be signature guaranteed. If you have changed your address within 30 days of a redemption request, a signature guarantee is required for any amount of redemption. For joint tenant accounts, each signature must be signature guaranteed. A signature guarantee helps protect you and the Funds from fraud. You can obtain a signature guarantee from most securities firms or banks, but not from a notary public. If you are redeeming $50,000 or less, per Fund, and if the proceeds are sent to the address of record (which has not been changed within 30 days), no signature guarantee is required.

Please call the Transfer Agent at 1-800-442-3814 if you are unsure of any of the special redemption requirements. Please remember that the Funds will not process redemptions greater than $50,000 per Fund until the original letter of instruction with the signature guarantee in proper form has been received by the Transfer Agent.

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.



		47		www.BaronFunds.com


Baron Funds^®		Information about your Investment

If you redeem more than $250,000 or 1% of the net asset value of a Fund during any 90-day period, that Fund has the right to pay the redemption price, either totally or partially, by a distribution of portfolio securities instead of cash.

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 52-54 of this prospectus and the “Taxation of the Funds” section on pages 34-40 in the accompanying 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



		1-800-99BARON		48


Information about your Investment		Baron Funds^®

on pages 32-35 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 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.

The policy of the Funds is to presume that a person who trades in and out of a Fund within six months or less is not a long-term investor. If the Adviser reasonably believes that a person is not a long-term investor, it will attempt to prohibit that person from investing in the Funds if it determines that such trading was disruptive to the Fund. The Adviser, in its sole discretion, will consider evidence that rebuts that presumption, including the existence of extenuating circumstances such as medical emergencies or other hardships. The Adviser will examine information that is reasonably available to it at the time, including information supplied by third parties and the shareholder’s investment history, to the extent known, in other mutual funds or investment vehicles (including vehicles managed by the Adviser or its affiliates), and if it is able to identify a person whom the Adviser deems is not a long-term investor, it will attempt to: (i) bar the person from returning to the Funds; or (ii) reject the investment from the outset. Although the Adviser may not be able to identify all persons who engage in frequent trading, it will make attempts to minimize frequent trading activity in the Funds. The Funds will not allow exchanges for an investor that the Adviser reasonably believes is not a long-term shareholder.

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



		49		www.BaronFunds.com


Baron Funds^®		Information about your Investment

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.

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 51-52 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 federal income tax purposes, and you may realize a taxable gain or loss. The policy of the Funds is to presume that a person who trades in and out of a Fund within six months or less is not a long-term investor (please see the “Policies Regarding Frequent Purchases and Redemptions of Fund Shares” section on pages 48-50 of this prospectus). Exchanges between funds within six months or less violate this policy. 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 two classes of shares, Retail Shares and Institutional 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. The transaction will be based on the relative net asset values of the respective securities to be exchanged on the trade date for the conversion. Such a conversion is not a taxable event.

The Funds, the Distributor, the Transfer Agent and the Adviser are not liable for any loss, liability, cost or expense for following instructions communicated through the Internet, including fraudulent or unauthorized instructions.

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 (“Qualifying Income”).

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) designated 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 a 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” in your taxable years beginning before January 1, 2013 will be treated as “qualified dividend income” received by you and will therefore be subject to U.S. federal income tax at the rates applicable to long-term capital gains. The Funds will inform you each year of the tax status of distributions you received for the previous year. Your tax liabilities for such distributions will depend on your particular tax situation.

If you elect 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.

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. Such distributions 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. However, you may be able to claim a tax credit or a deduction for your portion of any foreign withholding and income taxes paid by a Fund.

By law, 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 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, capital gains recognized by individuals and other non-corporate shareholders on a sale or redemption of shares generally are taxed at the rate of 15% if your holding period for your Shares is more than one year. Any loss realized on a sale or redemption will be disallowed to the extent your Shares disposed of are replaced 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 of 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 receive with respect to such shares.

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.

Taxability of Conversion of Shares

The Funds offer two classes of shares, Retail Shares and Institutional Shares, which differ only in their ongoing fees and eligibility requirements. You may convert Retail Shares into Institutional Shares if 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. The transaction will be based on the respective NAV of each class on the trade date for the conversion. 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.

Distribution Arrangements

12b-1 Plan

The Funds have adopted a distribution plan for Retail Shares under Rule 12b-1 of the Investment Company Act of 1940 (the “1940 Act”) that allows the Funds to pay distribution fees for the sale of Retail Shares and for services provided to shareholders. A substantial portion of the 12b-1 fees is directed to third parties that provide shareholder servicing to existing shareholders. Because the fees are paid out of the Funds’ assets attributable to the Retail Shares on an on-going basis, over time these fees will increase the cost of your investment in Retail Shares and may cost you more than paying other types of sales charges. 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 “Rule 12b-1 Plan” section on pages 27-29 of the SAI). The 12b-1 Plan does not apply to Institutional Shares.

Third Party Arrangements. The Adviser, the Distributor or their affiliates, may, at their own expense out of their own financial resources (a source of which may be payment under the Funds’ 12b-1 Plan for Retail Shares), make cash payments for shareholder services to some, but not all brokers, dealers or other financial intermediaries, as an incentive to sell shares of the Funds and/or promote retention of their customers’ assets in the Funds. These payments, sometimes 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.

Revenue sharing payments may be made to brokers, dealers or other financial intermediaries that provide services to the Funds or to shareholders of the Funds,



		1-800-99BARON		54


Information about your Investment		Baron Funds^®

including shareholder servicing, transaction processing, sub-accounting services, marketing support and/or access to sales meetings, sales representatives and management representatives of the broker, dealer or other financial intermediary. Revenue sharing payments may also be made to brokers, dealers or other financial intermediaries for inclusion of the Funds on a sales list, including a preferred or select sales list, in other sales programs, or as an expense reimbursement in cases where the broker, dealer or other financial intermediary provides shareholder services to Fund shareholders. Revenue sharing payments may be structured: (i) as a percentage of net sales; (ii) as a percentage of net assets; and/or (iii) as a fixed dollar amount.

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 would have omnibus accounts with the Transfer Agent, and provide shareholder servicing and/or sub-transfer agent services to shareholders or beneficial owners. It is anticipated that any amounts paid by the Funds to such financial intermediaries would not exceed the amount each Fund would have incurred in maintaining the shareholder accounts for those who invest in the Fund directly rather than through these financial intermediaries. As of December 31, 2010, 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 periods presented in the five year period ended September 30, 2010 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 Annual Financial Report can be found at www.BaronFunds.com.

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 medium-sized growth companies with undervalued assets or favorable growth prospects. Baron Asset Fund invests for the long term primarily in securities of medium-sized growth companies with market capitalizations at the time of purchase of between $1.5 billion and $12 billion. 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 for the long-term primarily in securities of small-sized growth companies with market capitalizations of up to $2.5 billion. A small-sized growth company is defined as one having a market capitalization of under $2.5 billion 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 with market capitalizations of up to $2.5 billion 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 Fifth Avenue Growth Fund’s investment goal is capital appreciation through investments primarily in the securities of large-sized growth companies with market capitalizations of greater than $5 billion at the time of purchase.

In addition to the investment strategies of the Funds described in each of their respective summary sections and in the prospectus on pages 32-35, the Funds may use the additional strategies described below. These investment strategies are not fundamental policies and may be changed by the Funds’ 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.

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 and Baron Fifth Avenue Growth 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. Investment 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 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, developing countries which are countries that from time to time comprise the MSCI Emerging Markets (EM) Index, and frontier countries which are countries that from time to time comprise the MSCI Frontier Markets (FM) Index.

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 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 US bank, or securities issued or guaranteed by the US 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 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 Securities.

The Funds may invest in debt and equity securities purchased on a when-issued basis. Although the payment and interest terms of when-issued securities are established at the time the purchaser enters into the commitment, the actual payment for and delivery of when-issued securities generally takes place within 45 days. The Funds bear the risk that interest rates on debt securities at the time of delivery may be higher or lower than those contracted for on the when-issued security.

Failure of the issuer to deliver the security purchased on a when-issued basis may result in a loss or missed opportunity to make an alternative investment. 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%, and Baron Growth Fund, Baron Small Cap Fund, Baron Opportunity Fund and Baron Fifth Avenue Growth Fund may invest up to 15%, of their respective net assets in securities that are illiquid. An illiquid security is one that cannot be disposed of in the ordinary course of business within seven days. Such investments may include private equity securities, PIPE 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 debt 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, although pursuant to Rule 144A under the Securities Act of 1933, certain securities may be determined to be liquid pursuant to procedures adopted by the Board under applicable guidelines. The Funds may invest in securities of distressed issuers when the intrinsic values of such securities, in the opinion of the Adviser, warrant such investment.

Debt 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.

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.

Many types of debt securities including 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 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 such 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, which 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 indebtedness. 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.

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.

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

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 may expose the Funds to greater fluctuations in the value of their assets.

Medium And Lower-Rated Corporate Debt Securities.

The Funds may invest in debt securities that are rated in the medium to lowest rating categories by Standard & Poor’s Corporation (“S&P”) and Moody’s Investors Services, Inc. (“Moody’s”), some of which may be known as “junk bonds.” The Funds do not anticipate investing more than 35% of their total assets in such securities.

The Funds will rely on the judgment, analysis and experience of the Adviser in evaluating debt securities. The Adviser believes that the difference between perceived risk and actual risk creates the opportunity for profit which can be realized through thorough analysis. Ratings by S&P and Moody’s evaluate only the safety of principal and interest payments, not market value risk. 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 credit ratings assigned by a rating agency to a security are not considered by the Adviser in selecting a security. The Adviser examines the intrinsic value of a security in light of market conditions and the underlying fundamental values. Because of the nature of medium and lower rated corporate debt securities, achievement by the Funds of their investment goals when investing in such securities is dependent on the credit analysis of the Adviser. The Adviser could be wrong in its analysis. If the Funds purchased primarily higher-rated debt securities, these risks would be substantially reduced.

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. The ability of issuers of medium and lower grade corporate debt securities to repay principal and to pay interest, to meet projected business goals and to obtain additional financing may be adversely affected by economic conditions. Such consequences could lead to an increased incidence of default for such securities and adversely affect the value of the corporate debt securities in a Fund’s portfolio. The secondary market prices of medium and lower grade corporate debt securities are more sensitive to adverse economic changes or individual corporate developments than are higher rated debt securities. Adverse publicity and investor perceptions, whether or not based on rational analysis, and periods of economic uncertainty may also affect the value and liquidity of medium and lower grade corporate debt securities, although such factors also present investment opportunities when prices fall below intrinsic values. 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 and Baron Fifth Avenue Growth 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 and Baron Fifth Avenue Growth 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 Funds to hold a security or instrument which they 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.

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 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.

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 technological advancement.

Use of Segregated and Other Special Accounts.

Many hedging transactions require, among other things, that the Funds segregate liquid high-grade 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. For example, a call option written by the Funds will require the Funds to hold the securities subject to the call (or securities convertible into the needed securities without additional consideration) or to segregate liquid securities sufficient to purchase and deliver the securities if the call is exercised. Hedging transactions may be covered by other means when consistent with applicable regulatory policies.

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 is not possible to effectively hedge the currency risks of many developing countries.

Geographic Risk.

Funds that are less diversified across geographic regions, countries, industries, or individual companies are generally riskier than more diversified funds. 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.

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, 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 net asset values. As a result, net asset values may be significantly affected on days when shareholders cannot make transactions.

Developing Countries.

The Funds’ investments in developing countries, which include countries in the MSCI Emerging Markets (EM) Index, are subject to all of the risks of foreign 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 frontier countries, which include countries in the MSCI Frontier Markets (FM) Index.

Share Classes.

The Funds offer two classes of shares, Retail Shares and Institutional 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 through the Baron Funds without paying a sales charge or any other additional fees. Employees and Trustees of the Baron Funds are not subject to the eligibility requirements for Institutional Shares. For more information, please see the “How to Purchase Shares” section on pages 42-44 of the accompanying prospectus. Baron Funds reserve the right, without prior notice, to change the eligibility requirements of its share classes, including the types of clients 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 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/ourfunds. 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.

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 of Trustee’s (the “Board”) 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, compliance risk and operational risk). As part of its oversight, the Board, acting at its scheduled meetings, or the Chairman, acting between Board meetings, regularly interacts with and receives reports from senior personnel of service providers, including the Adviser’s Chief Investment Officer, the Trust’s and the Adviser’s Chief Compliance Officer and portfolio management personnel. The Board’s Audit Committee (which consists of two 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 Trust or 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 a fund’s trustees not be “interested persons” (as defined in the 1940 Act) of the fund, and to rely on certain exemptive rules under the 1940 Act, a majority of a fund’s trustees must not be interested persons of the fund. 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 not interested persons of the fund. Currently, six of the Trustees are Independent Trustees. The Chairman of the Board, Linda Martinson, is an interested person of the Trust (“Interested Trustee”), and the Independent Trustees have designated two lead Independent Trustees who chair meetings or executive sessions of the Independent Trustees, review and comment on Board meeting agendas, represent the views of the Independent Trustees to management and facilitate 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 two lead Independent Trustees 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” of the Funds, as that term is defined in the 1940 Act by reason of their employment with the Funds’ Adviser and Distributor.

Each Trustee has been a Board member of the Trust and other Baron mutual funds for at least five 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 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, and also may benefit from information provided by the Trust’s or the Adviser’s counsel; both Board and Trust counsel have significant experience advising funds and fund board members. The Audit Committee of the Board 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.

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. While the Code of Ethics allows employees to invest in securities including, under very limited circumstances, securities held by the Funds, it is the current practice of the Funds, the Adviser and the Distributor to not permit such investments.

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 voting service, or (iii) appoint an independent third party to vote.

A full copy of the Firm’s Proxy Voting Policies and Procedures is available on the Baron Funds^® website, www.BaronFunds.com. The Funds’ most current Proxy Voting Record on Form N-PX for the twelve months ended June 30, 2010 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 and is the Adviser’s Chief Investment Officer. Mr. Baron has over 30 years of experience as a Wall Street analyst and has managed money for others for over 33 years. He has been a participant in Barron’s Roundtable and has been a featured guest on Wall Street Week, CNN and CNBC/FNN. Mr. Baron is the portfolio manager for Baron Growth Fund and was the co-portfolio manager of Baron Asset Fund until January 23, 2008.

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 and Baron Opportunity Fund of 1% of the average daily net assets of the respective Fund. Baron Fifth Avenue Growth Fund pays the Adviser 0.90% for average daily net assets under $1 billion, 0.85% for average daily net assets greater than $1 billion but less than $2 billion and 0.80% for average daily net assets over $2 billion.

Baron Asset Fund incurred advisory expenses of $27,630,230 for the year ended September 30, 2010; $23,278,874 for the year ended September 30, 2009; and $39,767,714 for the year ended September 30, 2008. Baron Growth Fund incurred advisory expenses of $55,277,765 for the year ended September 30, 2010; $42,540,631 for the year ended September 30, 2009; and $64,427,404 for the year ended September 30, 2008. Baron Small Cap Fund incurred advisory expenses of $30,957,041 for the year ended September 30, 2010; $22,255,597 for the year ended September 30, 2009; and $33,144,354 for the year ended September 30, 2008. Baron Opportunity Fund incurred advisory expenses of $1,878,277 for the year ended September 30, 2010; $1,153,709 for the year ended September 30, 2009; and $1,898,556 for the year ended September 30, 2008. Baron Fifth Avenue Growth Fund incurred advisory expenses of $411,210 for the year ended September 30, 2010; $392,191 for the year ended September 30, 2009; and $824,821 for the year ended September 30, 2008. The Adviser has contractually agreed to limit the expense ratio for the Retail Shares of Baron Opportunity Fund and Baron Fifth Avenue Growth Fund to 1.50% and 1.30%, respectively and for the Institutional Shares of Baron Opportunity Fund and Baron Fifth Avenue Growth Fund to 1.25% and 1.05% respectively, excluding portfolio transaction costs, interest and extraordinary expenses for so long as the Adviser serves as investment adviser to the Funds.

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 the 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.

The Advisory Agreements were approved by a majority of the Trustees, including a majority of the Independent Trustees for Baron Asset Fund on May 11, 1987, for Baron Growth Fund on October 21, 1994, for Baron Small Cap Fund on July 29, 1997, for Baron Opportunity Fund on January 18, 2000, and for Baron Fifth Avenue Growth Fund on March 10, 2004. The Advisory Agreements must normally be approved annually by the Board or a majority of the particular Funds’ shareholders and by a majority of the Trustees who are not parties to the Advisory Agreement or interested persons of any such party. Such approval for 2010 was given at a Board of Trustees meeting held on May 18, 2010.

Each Advisory Agreement is terminable without penalty by either the Funds (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). A discussion regarding the basis for the approval by the Board of the Advisory Agreements of the Funds is available in the Funds’ Annual Financial Report to Shareholders for the year ended September 30, 2010.

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.

Service Agreements.

The Funds have agreements with various service providers pursuant to which administrative services such as record keeping, reporting and processing services are provided to the Funds’ shareholders.

12b-1 Plan.¹

The Distributor does not receive underwriting commissions, but 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. Due to the possible continuing nature of Rule 12b-1 payments, long-term investors may pay more than the economic equivalent of the maximum front-end sales charge permitted by FINRA (the Financial Industry Regulatory Authority). The 12b-1 fees are paid to the Distributor in connection with its activities and expenses primarily intended to result in the sale of Retail Shares and the servicing of Retail Shares shareholder accounts, including, but not limited to, compensation to registered representatives or other employees of the Distributor, compensation to and expenses of employees of the Distributor who engage in or support the distribution of Retail Shares or who service Retail Shares shareholder accounts, telephone expenses, preparing, printing and distributing Retail Shares promotional and advertising material, preparing, printing and distributing the prospectus and reports to other than current shareholders, compensation for certain Retail Shares shareholder services, and commissions and other fees to brokers, dealers, other financial intermediaries or other persons who have introduced investors to the Funds. 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 Distributor or its affiliates may enter into arrangements with third parties to sell the Retail Shares of the Funds in programs that make Fund shares available to their customers and pay such third parties amounts in excess of the 12b-1 fees. The excess amounts typically represent savings of expenses the Funds would otherwise incur in performing record keeping and transfer agency functions. The Adviser reimburses the Distributor for certain of those excess charges.

The Distributor, the Adviser and/or their affiliates, at their expense, currently provide additional compensation to certain financial intermediaries to make Fund shares available to their customers. These financial intermediaries include retirement plan sponsors, service providers and administrators, which provide record-keeping and administrative services and other services to retirement plan participants, and banks, brokers, dealers and other financial intermediaries, insurance companies, and other service providers that provide distribution-related and shareholder services. The amount of payments made to a financial intermediary in any given year will vary based on the amount of Fund assets attributable to that financial intermediary. These payments help defray the costs incurred by financial intermediaries for, among other things, providing marketing and other services intended to assist in the offer and sale of Fund shares, for shareholder servicing activities and/or for sub-transfer agency services provided to individual shareholders, where a financial intermediary maintains omnibus accounts with DST Systems, Inc. (the “Transfer Agent”).

The expenses listed below are payable by the Funds and are not treated as distribution or service fees under the 12b-1 Plan, even though they are considered to be primarily intended to result in the sale of shares within the meaning of Rule 12b-1 of the 1940 Act: (a) the costs of preparing, printing or reproducing and mailing all required reports and notices to shareholders; (b) the costs of preparing, printing or reproducing and mailing all proxy statements and proxies (whether or not such proxy materials include any item relating to or directed toward the sale of shares); (c) the costs of preparing, printing or reproducing and mailing all prospectuses and SAIs to current shareholders; (d) all external legal and accounting fees relating to the preparation of any such report, prospectus, SAI and proxy materials; (e) all external fees and expenses relating to the qualification of the Fund and/or your Shares under the securities or “Blue Sky” laws of any jurisdiction; (f) all fees under the 1940 Act and the Securities Act of 1933, including fees in connection with any application for exemption relating to or directed toward the sale of shares; (g) all fees and assessments, if any, of the Investment Company Institute or any successor organization, whether or not its activities are designed to provide sales assistance; (h) all costs of preparing and mailing confirmations of shares sold or redeemed and reports of share balances; (i) all external costs of responding to telephone or mail inquiries of shareholders or prospective shareholders; and (j) all other external costs and expenses of an administrative nature.

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

The 12b-1 Plan requires that while it is in effect, the Distributor report to the Board in writing, at least quarterly, the amounts of all expenditures, the identity of the payees and the purposes for which such expenditures were made for the preceding fiscal quarter.

For the fiscal year ended September 30, 2010, Baron Asset Fund paid distribution fees attributable to Retail Shares to the Distributor of $6,429,104 (an additional $3,863,059 was absorbed by the Distributor and/or its affiliates and not paid by the Fund pursuant to the 0.25% limitation); Baron Growth Fund paid distribution fees to the Distributor of $12,449,851 (an additional $7,916,091) was absorbed by the Distributor and/or its affiliates and not paid by the Fund pursuant to the 0.25% limitation); Baron Small Cap Fund paid distribution fees to the Distributor of $7,279,541 (an additional $4,132,729 was absorbed by the Distributor and/or its affiliates and not paid by the Fund pursuant to the 0.25% limitation); Baron Opportunity Fund paid distribution fees to the Distributor of $431,201 (an additional $173,638 was absorbed by the Distributor and/or its affiliates and not paid by the Fund pursuant to the 0.25% limitation); and Baron Fifth Avenue Growth Fund paid distribution fees to the Distributor of $81,062 (an additional $23,431 was absorbed by the Distributor and/or its affiliates and not paid by the Fund pursuant to the 0.25% limitation).

The following table shows the principal types of activities for which payments are or will be made, including the dollar amount and the manner in which amounts were paid by the Funds under the 12b-1 Plan for the fiscal year ended September 30, 2010.


	Baron Asset Fund		Baron Growth Fund		Baron Small Cap Fund		Baron Opportunity Fund		Baron Fifth Avenue Growth Fund

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 Funds; and (ii) the consequent reduced expense ratios due to economies of scale, ability to purchase larger blocks of securities, which result in decreased expenses, and minimization of adverse effects from forced sales of portfolio securities to meet redemptions.

The Distributor is authorized to make payments to authorized brokers, dealers and other financial intermediaries who have rendered distribution assistance and ongoing shareholder support services, shareholder servicing assistance or record keeping. Certain states may require that any such person be registered with such state. The Funds may execute portfolio transactions with and purchase securities issued by depository institutions that receive payments under the 12b-1 Plan. No preference will be shown in the selection of investments for the instruments of such depository institutions. The Distributor may also retain part of the 12b-1 fee as compensation for its services and expenses in connection with the distribution of Retail Shares. 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.

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 the Funds’ shareholders. 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.

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 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.

A conflict could also arise when the portfolio manager has an investment in one Fund as opposed to another, or has a larger investment in one Fund than in others he manages. The Adviser or its affiliate may also receive a performance-based fee with respect to certain accounts, which could create a conflict.

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 and allocations of orders for execution to brokers), disclosure of confidential information and employee trading.

Compensation.

Mr. Baron has an employment agreement that includes a fixed base salary, a fixed bonus and a performance bonus based on a percentage of the management fees earned on the Funds that he manages. The terms of his contract are based on Mr. Baron’s role as the Firm’s Founder, Chief Executive Officer and Chief Investment 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 and Haase 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 and are eligible for special bonuses based on the Firm achieving its long-term growth and profitability goals.

BROKERAGE ALLOCATION AND OTHER PRACTICES

The Adviser is responsible for placing the portfolio brokerage business of the Funds with the goal of obtaining the best net results for the Funds, taking into account prompt, efficient and reliable executions at a favorable price.


For the Fiscal Year Ended 09/30	2010		2009		2008
Total Commissions Paid
Baron Asset Fund	$	1,180,227	$	782,877	$	1,136,759

Baron Fifth Avenue Growth Fund	$	37,579	$	16,302	$	32,112

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 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 affiliates to supplement the services it is required to perform pursuant to the Advisory Agreement in serving the Funds and/or other advisory clients of affiliates.

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 affiliates’ 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 account 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.

During the year ended September 30, 2010, the Funds purchased securities issued by the following regular broker-dealers of the Funds, which had the following value as of September 30, 2010:

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 five series currently available are Baron Asset Fund, Baron Growth Fund, Baron Small Cap Fund, Baron Opportunity Fund and Baron Fifth Avenue Growth 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.

Net Asset Value.

As more fully set forth in the prospectus under “How Your Shares are Priced,” the net asset value per share of each Fund is determined as of the close of regular trading of the New York Stock Exchange (the “Exchange”),

(usually 4:00 p.m. Eastern Standard Time) on each day that the Exchange is 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.

U.S. Government obligations and other debt instruments having sixty days or less remaining until maturity are stated at amortized cost. Debt instruments having a greater remaining maturity will be valued on the basis of prices obtained from a pricing service approved by the Board or at the mean between the bid and ask prices from a dealer maintaining an active market in that security.

Non-U.S. equity securities are valued on the basis of their most recent closing market prices and translated into U.S. dollars at 4 p.m. E.T. except under the circumstances described below. Most foreign markets close before 4 p.m. E.T. For securities primarily traded in the Far East, for example, the most recent closing prices may be as much as 15 hours old at 4 p.m. E.T. If the Adviser determines that developments between the close of the foreign market and 4 p.m. E.T. may, in its judgment, materially affect the value of some or all of the Funds’ securities, the Adviser will adjust the previous closing prices to reflect what it believes to be the fair value of the securities as of 4 p.m. E.T. In deciding whether to make these adjustments, the Adviser reviews a variety of factors, including developments in foreign markets, the performance of U.S. securities markets, and the performance of instruments trading in U.S. markets that represent non-U.S. securities and baskets of non-U.S. securities. 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 uses outside pricing services to provide it with closing market prices and information used for adjusting those prices. The Adviser cannot predict how often it will use closing prices and how often it will adjust those prices.

TAXATION OF THE FUNDS

The accompanying 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 accompanying 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 or to shareholders subject to special treatment under U.S. federal income tax laws (e.g., 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 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 securities or options thereon or foreign currencies, other income derived with respect to its business of investing in such 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 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 assets is invested in the securities of any one issuer (other than U.S. government securities and securities of other regulated investment companies), in 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 in one or more “qualified publicly traded partnerships,” as defined in the Code.

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” 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 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.

If for any taxable year the Fund does 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 will 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 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 during a taxable year of the shareholder beginning before January 1, 2013 would be taxable to the shareholder as “qualified dividend income” to the extent of the Fund’s earnings and profits. However, if the Fund fails 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, curing such failure and possibly paying an additional tax. 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.

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 might 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 the PFIC’s stock exceeds the Fund’s adjusted basis in these shares. If the Fund’s adjusted basis in the shares of a PFIC exceeds the shares’ fair market value at the end of a taxable year, the Fund would 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 elect to include as income and gain its share of the ordinary earnings and net capital gain of certain 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, 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 to 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). In addition, these rules 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 the Fund’s investment company taxable income and, as a result, the 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 Internal Revenue Service 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 taxable 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.

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. For this purpose, the portion of dividends and distributions 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 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 proportionate 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 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. 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 a shareholder’s adjusted basis in his shares, and as a capital gain thereafter.

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” in taxable years of a noncorporate shareholder beginning before January 1, 2013 will be treated as “qualified dividend income” received by the 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 report its share of such undistributed net capital gain 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.

The Fund will inform its shareholders each year of the tax status of distributions received by shareholders for the previous year. A shareholder’s tax liability for such distributions will depend on the shareholder’s particular tax situation.

Shareholders electing 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, 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. 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. Such distributions will be taxable to shareholders as if received on December 31 of such prior year, rather than in the year in which the distributions are actually received.

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 includes the amount of the forthcoming distribution, the distribution will nevertheless be taxable to the purchaser.

As of September 30, 2010, the Funds had capital loss carryforwards expiring as follows:

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 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 in taxable years of the shareholder beginning before January 1, 2013 by individuals and other non-corporate shareholders on a sale or redemption of shares generally are taxed at a maximum rate of 15%. Any loss realized on a sale or redemption will be disallowed to the extent the shares disposed of are replaced 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 is 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 Internal Revenue Service 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 Internal Revenue Service Form 8886 in connection with a sale or other disposition of shares.

Conversion of Shares.

The Fund offers two classes of shares, Retail Shares and Institutional 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. The transaction will be based on the respective net asset value per share of each class on the trade date for the conversion. 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.

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, currently at the rate of 28%, if payable to shareholders who fail to provide the Fund (or other payor) with its correct taxpayer identification number or to make required certifications, or who have been notified by the Internal Revenue Service that they are subject to backup withholding. Certain shareholders specified in the Code 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 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 and that the foreign shareholder is not an expatriate. 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 in its taxable years beginning before January 1, 2012 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). It is unclear whether any legislation will be enacted that would extend this exemption from withholding for the Fund’s taxable years beginning on or after January 1, 2012.

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.

In general, a foreign shareholder will not be subject to U.S. federal income or withholding tax with respect to gain on the sale or redemption of shares of the Fund, distributions by the Fund of net capital gains (that is, the excess of net long-term capital gain over net short-term capital loss) or amounts retained by the Fund that are designated as undistributed net capital gains. In the case of a foreign shareholder who is a nonresident alien individual, gain arising from the sale or redemption of shares of the Fund, distributions of net capital gains and amounts retained by the Fund that are designated as undistributed net capital gains ordinarily will be subject to U.S. income tax at a rate of 30% if such individual is present in the United States for 183 days or more during the taxable year and, in the case of gain arising from the sale or redemption of Fund shares, either the gain is attributable to an office or other fixed place of business maintained by the shareholder in the United States or the shareholder has a “tax home” in the United States.

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 Internal Revenue Service on a timely basis.

In order to qualify for the exemption from U.S. withholding tax on “interest-related dividends,” 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 a properly executed Internal Revenue Service form (generally, Form W-8BEN). 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, a foreign shareholder must obtain a U.S. taxpayer identification number and file a U.S. federal income tax return.

The Fund does not expect to be a “United States real property holding corporation;” however, if the Fund were a “United States real property holding corporation,” special rules would apply to a foreign shareholder’s receipt of distributions from the Fund and gains realized upon a foreign shareholder’s redemption or other disposition of the Fund’s shares. If the Fund were a “United States real property holding corporation” as defined for U.S. federal income tax purposes without the application of certain specified exceptions, a distribution to a foreign shareholder who owned more than 5% of the Fund’s shares at any time during the one-year period ending on the date of the distribution would be subject to special rules. Generally, such a distribution, to the extent of the Fund’s own receipt of a distribution from a “real estate investment trust,” would be subject to withholding tax and such foreign shareholder would be required to file a U.S. federal income tax return. In addition, such a distribution to a foreign shareholder out of gain from the Fund’s sale or other disposition of a “United States real property interest” made in taxable years beginning before January 1, 2012 would be subject to withholding tax and the foreign shareholder receiving such distribution would be required to file a U.S. federal income tax return. If the Fund were a “United States real property holding corporation” for U.S. federal income tax purposes, any gain from the disposition of Fund shares realized by a foreign shareholder that has owned more than 5% of the relevant class of the Fund’s shares at any time during the five-year period ending on the date of the disposition would generally be subject to U.S. income and withholding tax and the shareholder would be required to file a U.S. federal income tax return.

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.

Recent legislation generally imposes withholding at a rate of 30% on payments to certain foreign entities (including financial intermediaries), after December 31, 2012, of dividends on and the gross proceeds of dispositions of U.S. common stock, unless the relevant foreign entity satisfies various U.S. information reporting and due diligence requirements (generally relating to ownership by U.S. persons of interests in or accounts with those entities). Shareholders should consult their tax advisors regarding the possible implications of this legislation on their investments 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.

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.

CALCULATIONS OF PERFORMANCE DATA

Advertisements and other sales literature for the Funds may refer to average annual total return and actual return. Average annual total return is computed by finding the average annual compounded rates of return over a given period that would equate a hypothetical initial investment to the ending redeemable value thereof, as follows:

P(1+T)ⁿ = ERV

Where:

P = a hypothetical initial payment of $1,000

T = average annual total return

ⁿ = number of years

ERV = ending redeemable value at the end of the period of a hypothetical $1,000 investment made at the beginning of the period

Actual return is computed by measuring the percentage change between the net asset value of a hypothetical $1,000 investment in the Funds at the beginning of a period and the net asset value of that investment at the end of a period.

After-tax returns are included in the table below to show the impact of assumed federal income taxes on an investment in the Funds’ Retail Shares. A Fund’s total return “after taxes on distributions” shows the effect of taxable distributions, but not any taxable gain or loss, on an investment in shares of the Fund for a specified period of time. A Fund’s total return “after taxes on distributions and sale” shows the effect of both taxable distributions and any taxable gain or loss realized by the shareholder upon the sale of fund shares at the end of a specified period. To determine these figures, all income, short-term capital gain distributions and long-term capital gain distributions are assumed to have been taxed at the highest marginal individualized federal tax rate then in effect. Those maximum tax rates are applied to distributions prior to reinvestment and the after-tax portion is assumed to have been reinvested in the Funds. State and local taxes are ignored. The table also shows the average annual returns of the Funds’ Institutional Shares, but it does not show after-tax returns.

Actual after-tax returns depend on a shareholder’s tax situation and may differ from those shown. After-tax returns reflect past tax effects only and are not predictive of future tax effects.

Average Annual Total Return (After Taxes on Distributions) is computed as follows:

ATV_D = P (1+T)ⁿ

Where:

P = a hypothetical initial payment of $1,000

T = average annual total return (after taxes on distributions)

ⁿ = number of years

ATV_D = ending redeemable value of a hypothetical $1,000 investment made at the beginning of the period, at the end of the period (or fractional portion thereof), after taxes on fund distributions but not after taxes on redemptions.

Average Annual Total Return (After Taxes on Distributions and Sale of Fund Shares) is computed as follows:

ATV_DR = P (1+T)ⁿ

Where:

P = a hypothetical initial payment of $1,000

T = average annual total return (after taxes on distributions and redemption)

ⁿ = number of years

ATV_DR = ending redeemable value of a hypothetical $1,000 investment made at the beginning of the period, at the end of the period (or fractional portion thereof), after taxes on fund distributions and redemptions.

All performance calculations assume that dividends and distributions are reinvested at the net asset value on the appropriate reinvestment dates and include all recurring fees.

Computed in the manner described above, the performance, as of September 30, 2010, for Baron Asset Fund, Baron Growth Fund, Baron Small Cap Fund, Baron Opportunity Fund and Baron Fifth Avenue Growth Fund has been:

The Russell MidCap Growth has replaced the NASDAQ Composite as the primary broad-based index for Baron Opportunity Fund because the Adviser believes that the Russell MidCap Growth is more representative of the Fund’s investment strategy. The NASDAQ Composite remains in the table above for comparison purposes.

#	Performance prior to May 29, 2009 is based on the performance of the Retail Shares which have a distribution fee. The Institutional Shares do not have a distribution fee. If the annual returns did not reflect this fee, the returns would be higher.

Performance results represent past performance and are not necessarily representative of future results. Investment return and principal value will fluctuate so that shares may be worth more or less than their original cost when redeemed.

Indemnification

Article IV of Registrant’s Declaration of Trust states as follows:

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.
