MANAGEMENT’S DISCUSSION OF FUND PERFORMANCE

For the 12 months ended September 30, 2023, Baron Asset Fund¹ gained 16.80%, while the Russell Midcap Growth Index gained 17.47% and the S&P 500 Index gained 21.62%.

Baron Asset Fund invests primarily in medium-sized growth companies for the long term, using a value-oriented purchase discipline. The Fund purchases companies that we believe have sustainable competitive advantages, strong financial characteristics, and exceptional management; and operate in industries with favorable growth characteristics.

U.S. markets rallied through the first 10 months of the year-long period, led by the “Magnificent Seven” mega-cap technology stocks. The period was marked by low unemployment, wage increases, and robust consumer spending. Investor optimism that the U.S. Federal Reserve had successfully engineered a soft landing and there was a possible end in sight to the Fed’s tightening regime helped propel gains. That sentiment soured in the last two months as inflation which, while significantly lower than its June 2022 peak, remained above Fed target levels. This higher-for-longer rate scenario weighed on growth stocks in particular. In addition, Treasury note yields vaulted to 15-year highs, prompting investors to shift assets into fixed income instruments.

Information Technology, Health Care, and Industrials contributed the most. Real Estate and Communication Services detracted.

Gartner, Inc. was the top contributor. Shares of this provider of syndicated research rose on solid financial results, with strength in its core subscription research and conferences businesses more than offsetting a decline in lead generation services. We believe Gartner will emerge as a key decision support resource for every company evaluating how AI could impact its business. We expect Gartner’s sustained revenue growth and focus on cost control to drive margin expansion and enhanced free-cash-flow generation. Its balance sheet is in excellent shape and can support aggressive repurchases and bolt-on acquisitions.

ZoomInfo Technologies Inc., a provider of go-to-market business intelligence software, was the top detractor. Shares fell after the company substantially cut full-year guidance, citing macro-related weakness. While we believe the environment is showing signs of stabilization, it is too early to say whether it is close to real improvement. Our research and conversations with management and industry experts suggest ZoomInfo remains competitively advantaged and has the best contact data, but the subsector faces uncertain macro conditions. We exited our position.

As long-term investors who have lived through multiple bear markets, downturns, and even recessions, we have learned not to try to predict the unpredictable. Instead, we focus on fundamentals: industry-leading companies benefiting from secular growth drivers, strong competitive positions, and exceptional management teams. We believe our companies will revert to historic growth rates and earnings will increase. Stocks should also revert to trading at appropriate multiples. We believe higher earnings and multiples will result in strong returns for the portfolio.

MANAGEMENT’S DISCUSSION OF FUND PERFORMANCE

For the 12 months ended September 30, 2023, Baron Growth Fund¹ increased 19.17%, while the Russell 2000 Growth Index increased 9.59% and the S&P 500 Index increased 21.62%.

Baron Growth Fund invests primarily in small-sized U.S. growth companies for the long term. Through independent research, we utilize an investment approach that we believe allows us to look at a business’s fundamental characteristics and beyond the current market environment. We invest based on the potential profitability of a business at what we believe are attractive valuations.

U.S. markets rallied through the first 10 months of the year-long period, led by the “Magnificent Seven” mega-cap technology stocks. The period was marked by low unemployment, wage increases, and robust consumer spending. Investor optimism that the U.S. Federal Reserve had successfully engineered a soft landing and there was a possible end in sight to the Fed’s tightening regime helped propel gains. That sentiment soured in the last two months as inflation which, while significantly lower than its June 2022 peak, remained above Fed target levels. This higher-for-longer rate scenario weighed on growth stocks in particular. In addition, Treasury note yields vaulted to 15-year highs, prompting investors to shift assets into fixed income instruments.

Financials, Information Technology, and Health Care contributed the most. Real Estate detracted.

Specialty insurance company Arch Capital Group Ltd. contributed the most to performance. Shares rose on four consecutive quarters of strong financial results, driven by favorable pricing trends in the P&C insurance market and investment income in a higher interest rate environment. Arch also benefited from inclusion in the S&P 500 Index, which prompted buying from passive funds. We continue to own the stock due to Arch’s strong management team and our expectation of strong growth in earnings and book value.

Alexandria Real Estate Equities, Inc. was the top detractor. Shares of this life sciences REIT fell due to broader weakness among REITS in the higher interest rate environment. Investor concerns that rent growth may slow due to moderating demand for space from certain industries, combined with an increase in new buildings with vacancies coming online, also pressured shares. We expect Alexandria’s portfolio to outperform the broader life science market given its differentiated cluster model and captive tenant base. We remain excited about Alexandria’s long-term prospects and view the current valuation as attractive.

We believe no one can accurately and consistently predict short-term market movements. Instead, we remain focused on identifying and researching well-managed unique businesses with significant barriers to entry and compelling growth prospects, investing in them at attractive prices, and holding them for the long term.

MANAGEMENT’S DISCUSSION OF FUND PERFORMANCE

For the 12 months ended September 30, 2023, Baron Small Cap Fund¹ increased 17.42%, while the Russell 2000 Growth Index increased 9.59% and the S&P 500 Index increased 21.62%.

Baron Small Cap Fund invests primarily in small-cap growth companies for the long term. The Fund invests in what we believe are well-run small-cap growth businesses that can be purchased at prices that represent a significant discount to our assessment of future value.

U.S. markets rallied through the first 10 months of the year-long period, led by the “Magnificent Seven” mega-cap technology stocks. The period was marked by low unemployment, wage increases, and robust consumer spending. Investor optimism that the U.S. Federal Reserve had successfully engineered a soft landing and there was a possible end in sight to the Fed’s tightening regime helped propel gains. That sentiment soured in the last two months as inflation which, while significantly lower than its June 2022 peak, remained above Fed target levels. This higher-for-longer rate scenario weighed on growth stocks in particular. In addition, Treasury note yields vaulted to 15-year highs, prompting investors to shift assets into fixed income instruments.

Industrials, Consumer Discretionary, and Financials contributed the most. Consumer Staples detracted.

Vertiv Holdings Co, a provider of critical infrastructure solutions to the data center industry, contributed the most. As one of the leading vendors of thermal management to data centers, Vertiv is broadly viewed by investors as a beneficiary of the growth in AI and corresponding investment in more complex cooling systems necessitated by the expected increase in the energy density of data centers. In addition, under its new CEO, Vertiv is reporting strong margins and free cash flow and proving itself as a strong operator with skilled execution. These two factors led to multiple expansion as investors gained confidence in the duration of the growth trajectory as well as Vertiv’s ability to capture the opportunity. Longer term, we see upside in earnings power as Vertiv closes the margin gap with peers and benefits from industry growth.

Driven Brands Holdings Inc. was the top detractor. Driven Brands is the largest automotive services company in North America, with more than 4,800 locations. The stock declined after the company reduced guidance given weakness in the car wash business and integration delays with its recent foray into the glass repair and replacement segment. Despite these challenges, the company’s growth potential remains strong, and we retain conviction in Driven Brand’s longer-term outlook.

Longer term, we believe strongly that our companies will revert to their historic growth rates and earnings will be considerably higher. Stocks will revert to trading at appropriate multiples, which, for the most part, are higher than present, irrespective of where interest rates settle out. We believe the combination of higher earnings and higher multiples will boost stock prices and produce solid returns for the portfolio.

MANAGEMENT’S DISCUSSION OF FUND PERFORMANCE

For the 12 months ended September 30, 2023, Baron Opportunity Fund¹ increased 24.07%, while the Russell 3000 Growth Index increased 26.63% and the S&P 500 Index increased 21.62%.

Baron Opportunity Fund invests primarily in U.S. growth companies that we believe are driving or benefiting from innovation through development of pioneering, transformative, or technologically advanced products and services. The Fund invests in high-growth businesses of any market capitalization, selected for their capital appreciation potential.

U.S. markets rallied through the first 10 months of the year-long period, led by the “Magnificent Seven” mega-cap technology stocks. The period was marked by low unemployment, wage increases, and robust consumer spending. Investor optimism that the U.S. Federal Reserve had successfully engineered a soft landing and there was a possible end in sight to the Fed’s tightening regime helped propel gains. That sentiment soured in the last two months as inflation which, while significantly lower than its June 2022 peak, remained above Fed target levels. This higher-for-longer rate scenario weighed on growth stocks in particular. In addition, Treasury note yields vaulted to 15-year highs, prompting investors to shift assets into fixed income instruments.

Information Technology, Financials, and Industrials contributed the most. Materials and Consumer Discretionary were slight detractors.

NVIDIA Corporation contributed the most. Shares of this fabless semiconductor company soared on developments in generative AI as evidenced by the release of ChatGPT and GPT-4. These technologies hold the promise of enabling significant productivity gains across domains such as content creation, coding, and even biologic discovery. We believe NVIDIA’s end-to-end AI platform and leading share in gaming, data centers, and autonomous machines, along with the size of these markets, will enable the company to benefit from durable growth for years to come.

ZoomInfo Technologies Inc. was the top detractor. Shares of this provider of business intelligence software fell after the company substantially cut full-year guidance, citing macro-related weakness. While we believe the environment is showing signs of stabilization, it is too early to say whether it is close to real improvement. Longer term, we continue to believe ZoomInfo can become a much larger company as it grows into its $70 billion-plus total addressable market with the potential to expand into marketing and talent acquisition software and other adjacencies.

We believe no one can accurately and consistently predict short-term market movements. Instead, we focus on identifying the secular growth trends and the companies with durable competitive advantages, profitable business models, and long-term-oriented managers driving or riding these trends. We establish and monitor price targets for holdings and target companies using projections of revenues, earnings, and free cash flow and appropriate multiples, and invest at prices where we believe we can produce substantial returns.

Baron Fifth Avenue Growth Fund focuses on identifying and investing in what we believe are unique companies with durable competitive advantages and the ability to redeploy capital at high

rates of return. The portfolio is constructed on a bottom-up basis, with the quality of ideas and conviction level the most important determinants of the size of each investment. We expect our highest conviction businesses to have meaningful weight in the portfolio.

U.S. markets rallied through the first 10 months of the year-long period, led by the “Magnificent Seven” mega-cap technology stocks.

As long-term investors who have lived through multiple bear markets, downturns, and even recessions, we have learned not to try to predict the unpredictable. Instead of focusing on short-term market gyrations, our goal remains to maximize long-term returns without taking significant risks of a permanent loss of capital. We are optimistic about the prospects of our investments and continue searching for new ideas while remaining patient and investing only when we believe companies are trading significantly below their intrinsic values.

MANAGEMENT’S DISCUSSION OF FUND PERFORMANCE

For the 12 months ended September 30, 2023, Baron Discovery Fund¹ increased 9.03%, while the Russell 2000 Growth Index increased 9.59% and the S&P 500 Index increased 21.62%.

Baron Discovery Fund invests primarily in small-sized U.S. companies which at time of purchase have market capitalizations up to the largest market cap stock in the Russell 2000 Growth Index at June 30, or companies with market capitalizations up to $2.5 billion, whichever is larger.

U.S. markets rallied through the first 10 months of the year-long period, led by the “Magnificent Seven” mega-cap technology stocks. The period was marked by low unemployment, wage increases, and robust consumer spending. Investor optimism that the U.S. Federal Reserve had successfully engineered a soft landing and there was a possible end in sight to the Fed’s tightening regime helped propel gains. That sentiment soured in the last two months as inflation which, while significantly lower than its June 2022 peak, remained above Fed target levels. This higher-for-longer rate scenario weighed on growth stocks in particular. In addition, Treasury note yields vaulted to 15-year highs, prompting investors to shift assets into fixed income instruments.

Information Technology, Industrials, and Consumer Discretionary contributed the most. Health Care was the only significant sector detractor.

Specialty insurer Kinsale Capital Group, Inc. was the top contributor. Market conditions remained favorable, with rising premium rates and more business shifting from the standard lines market to the excess and surplus lines market where Kinsale operates. The company is also capitalizing on disruption in the property market, where rates are rising rapidly after years of industry losses and a reduction in reinsurance capacity. We continue to own the stock because we believe Kinsale is well managed and has a long runway for growth in an attractive segment of the insurance market.

Silk Road Medical, Inc. was the top detractor. Silk Road sells medical devices for minimally invasive transcarotid artery revascularization (TCAR) procedures. Medicare is updating reimbursement for an alternative carotid procedure (TF-CAS) to be equivalent to TCAR and investors are debating the competitive impact. We believe TCAR is less invasive, has an easier recovery, and causes fewer periprocedural strokes than other options. Following the FDA’s 2022 approval of Silk Road devices to treat standard surgical risk carotid stenosis patients, the company saw rising numbers of eligible patients, accelerated use of its products, reduced reimbursement uncertainty, and further legitimization of TCAR in the eyes of more conservative surgeons. Currently accounting for nearly 15% of carotid stenosis interventions, TCAR should become the standard of care for treating carotid artery disease over the long term, in our view.

No one can accurately and consistently predict short-term market movements, in our experience. Instead, we stay focused on identifying and investing in our competitively advantaged, emerging growth businesses for the long term. By staying true to our time-tested investment process, we believe our shareholders will be rewarded when the inevitable economic recovery begins.

MANAGEMENT’S DISCUSSION OF FUND PERFORMANCE

For the 12 months ended September 30, 2023, Baron Durable Advantage Fund¹ increased 33.36% while the S&P 500 Index increased 21.62%.

Baron Durable Advantage Fund invests mainly in large-sized U.S. companies with competitive advantages and market capitalizations no smaller than the top 90^th percentile by market

capitalization of the S&P 500 Index at June 30, or companies with market capitalizations above $10 billion, whichever is smaller. The Fund emphasizes businesses with excess free cash flow that can be returned to shareholders.

U.S. markets rallied through the first 10 months of the year-long period, led by the “Magnificent Seven” mega-cap technology stocks. The period was marked by low unemployment, wage increases, and robust consumer spending. Investor optimism that the U.S. Federal Reserve had successfully engineered a soft landing and there was a possible end in sight to the Fed’s tightening regime helped propel gains. That sentiment soured in the last two months as inflation which, while significantly lower than its June 2022 peak, remained above Fed target levels. This higher-for-longer rate scenario weighed on growth stocks in particular. In addition, Treasury note yields vaulted to 15-year highs, prompting investors to shift assets into fixed income instruments.

Information Technology, Financials, and Communication Services contributed the most. No sector detracted.

Meta Platforms, Inc. was the top contributor. Shares of the world’s largest social network increased on decisive cost discipline actions, improving adoption of new advertising products, and its work in generative AI. Meta is the mega-cap technology company most focused on cost cutting, while user engagement remains healthy and newer advertising formats are reportedly picking up steam. Longer term, we believe Meta will utilize its leadership in mobile advertising, massive user base, innovative culture, and technological scale to perform, with further monetization opportunities ahead.

Danaher Corporation was the top detractor. Shares of this life sciences and diagnostics company fell after it cut guidance due to headwinds within its bioprocessing segment, as biopharmaceutical customers burned through existing inventory and smaller biotechnology companies faced funding constraints. We retain conviction. Danaher is a market leader with a broad portfolio of high-quality assets within bioprocessing, a rapidly growing market that we expect to benefit from a wave of biosimilars entering the market after key patents expire.

As long-term investors who have lived through multiple bear markets, downturns, and even recessions, we have learned not to try to predict the unpredictable. Instead of focusing on short-term market gyrations, we believe that investing in great businesses at attractive valuations will enable us to earn excess risk-adjusted returns over the long term. We look for companies with strong and durable competitive advantages, track records of successful capital allocation, high returns on invested capital, and high free cash flow generation, a portion of which is regularly returned to shareholders as dividends or share repurchases.

NOTES TO FINANCIAL STATEMENTS

1. ORGANIZATION

Baron Investment Funds Trust (the Trust) is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company established as a Massachusetts business trust on February 19, 1987. The Trust currently offers seven series (individually, a Fund and collectively, the Funds): Baron Asset Fund, Baron Growth Fund, Baron Small Cap Fund, Baron Opportunity Fund, Baron Fifth Avenue Growth Fund, Baron Discovery Fund, and Baron Durable Advantage Fund.

Each Fund offers Retail Shares, Institutional Shares, and R6 Shares. Each class of shares differs only in its ongoing fees, expenses, and eligibility requirements. Each class of shares has equal rights to earnings and assets, except that each class bears different expenses for distribution and shareholder servicing. Each Fund’s investment income, realized and unrealized gains or losses on investments and foreign currency, and expenses other than those attributable to a specific class are allocated to each class based on its relative net assets. Each class of shares has exclusive voting rights with respect to matters that affect just that class.

Each Fund is diversified. The investment goals of the Funds are as follows:

Baron Asset Fund seeks capital appreciation through long-term investments primarily in securities of medium-sized companies with undervalued assets or favorable growth prospects.

Baron Growth Fund seeks capital appreciation through long-term investments primarily in securities of small-sized growth companies.

Baron Small Cap Fund seeks capital appreciation through investments primarily in securities of small-sized growth companies.

Baron Opportunity Fund seeks capital appreciation through investments primarily in growth companies that benefit from technology advances.

Baron Fifth Avenue Growth Fund seeks capital appreciation through investments primarily in securities of large-sized growth companies.

Baron Discovery Fund seeks capital appreciation through investments primarily in securities of small-sized growth companies.

Baron Durable Advantage Fund seeks capital appreciation through long-term investments primarily in securities of large-sized companies.

2. SIGNIFICANT ACCOUNTING POLICIES AND INVESTMENT RISKS

The following is a summary of significant accounting policies followed by the Funds. The policies are in conformity with accounting principles generally accepted in the United States of America (GAAP). The Trust is an investment company and therefore follows the investment company accounting and reporting guidance of the Financial Accounting Standards Board (FASB) Accounting Standard Codification Topic 946 Financial Services — Investment Companies.

a) Net Asset Value.  The Funds’ share prices or net asset values (NAV) are calculated as of the scheduled close of the regular trading session (usually 4 p.m. E.T. or such other time as of which the Funds’ NAVs are calculated (the NAV Calculation Time)) on the New York Stock Exchange (the Exchange) on any day the Exchange is scheduled to be open. The NAV per share of a class is determined by dividing the value of the total assets of the Fund represented by such class, less all liabilities, by the total number of Fund shares of such class outstanding.

b) Security Valuation.  Portfolio securities traded on any national stock exchange are valued based on the last sale price on the exchange where such shares are principally traded. For securities traded on NASDAQ, the Funds use the NASDAQ Official Closing Price. If there are no sales on a given day, the value of the security may be the average of the most recent bid and asked quotations on such exchange or the last sale price from a prior day. Where market quotations are not readily available, or, if in BAMCO, Inc.’s (the Adviser) judgment, they do not accurately reflect the fair value of a security, or an event occurs after the market close but before the Funds are priced that materially affects the value of a security, the security will be valued by the Adviser using policies and procedures approved by the Board of Trustees (the Board). The Board has designated the Adviser to perform fair value determinations pursuant to Rule 2a-5 under the 1940 Act. The Adviser has a Fair Valuation Committee (the Committee) comprised of senior management representatives and the Committee reports to the Board every quarter. Accordingly, the Committee may evaluate a variety of factors to determine the fair value of securities for which market quotations are determined not to be readily available or reliable. These factors include, but are not limited to, the type of security, the value of comparable securities, observations from financial institutions and relevant news events. Input from the Adviser’s portfolio management team also will be considered. Using a fair value pricing methodology to price securities may result in a value that is different from the most recent closing price of a security and from the prices used by other investment companies to calculate their portfolios’ NAVs.

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

Non-U.S. equity securities traded on foreign securities exchanges are generally valued using an independent pricing vendor that provides daily fair value adjustment factors based on information such as local closing price, relevant general and sector indexes, currency fluctuations, and depositary receipts, as applicable. Securities valued using such adjustment factors are classified as Level 2 in the fair value hierarchy. The models of the independent pricing vendor generate an adjustment factor for each security, which is applied to the local closing price to adjust it for post-closing market movements up to the time the Funds are valued and translated into U.S. dollars. If the vendor

36

NOTES TO FINANCIAL STATEMENTS (Continued)

2. SIGNIFICANT ACCOUNTING POLICIES AND INVESTMENT RISKS (Continued)

does not provide an adjustment factor for a security, the security is valued based on its most recent local closing price and translated into U. S. dollars. The Adviser may also fair value securities in other situations, for example, when a particular foreign market is closed but the Funds are open. Other mutual funds may adjust the prices of their securities by different amounts.

c) Securities Transactions and Investment Income.  Fund securities transactions are accounted for on trade date. Realized gain and loss from securities transactions are recorded on an identified cost basis for financial reporting and federal income tax purposes. Dividend income is recognized on the ex-dividend date and interest income is recognized on an accrual basis, which includes the accretion of discounts and amortization of premiums. Non-cash dividends received in the form of stock, if any, are recognized on the ex-dividend date and recorded as non-cash dividend income at fair value. Certain dividends from foreign securities will be recorded as soon as the Funds are informed of the dividend if such information is obtained subsequent to the ex-dividend date. Distributions received from certain investments held by the Funds may be comprised of dividends, realized gains and returns of capital. The Funds originally estimate the expected classification of such payments and the amounts may subsequently be reclassified upon receipt of information from the issuer.

d) Expense Allocation.  The Funds are charged for those expenses that are directly attributable to each Fund, such as advisory and custodian fees. Expenses of the Trust and Baron Select Funds (collectively, the Fund Complex), not directly chargeable to one or more specific Baron funds are typically allocated among the funds in the Fund Complex in proportion to their respective net assets. The Funds accrue distribution and service (12b-1) fees to Retail Shares.

e) Use of Estimates.  The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the amounts of income and expenses during the period. Actual results could differ from those estimates.

f) Foreign Currency Translations.  The accounting records of the Funds are maintained in U.S. dollars. Values of assets and liabilities denominated in foreign currencies are translated into U.S. dollars using the price of such currencies at the NAV Calculation Time. Purchases and sales of investments and dividend income are converted at the prevailing rate of exchange on the respective dates of such transactions. Net realized gain (loss) on foreign currency transactions includes gain (loss) arising from the fluctuation in the exchange rates between trade and settlement dates on security transactions and currency gain (loss) between the accrual and payment dates on dividends and foreign withholding taxes. The Funds do not isolate the portion of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in their market prices. Such fluctuations are included with the net realized and unrealized gain or loss from investments on the Statements of Operations. The Funds may invest in foreign securities and foreign currency transactions that may involve risks not associated with domestic investments as a result of the level of governmental supervision and regulation of foreign securities markets and the possibility of political or economic instability, among others.

Pursuant to U.S. federal income tax regulations, gains and losses from certain foreign currency transactions and the foreign currency portion of gains and losses realized on sales and maturities of foreign denominated debt securities are generally treated as ordinary income for U.S. federal income tax purposes.

g) Securities Lending.  The Funds may lend securities to certain brokers under the terms of a master netting agreement. Upon such loans, the Funds receive collateral which is maintained by the custodian. The Funds may pay fees to the custodian for administering the securities lending program. The Funds earn interest on such collateral and earn income in the form of negotiated lenders’ fees, both of which are included in securities lending income in the Statements of Operations. Securities loaned are required to be secured at all times by collateral equal to at least 102% of the market value of the securities loaned. Risks may arise upon entering into securities lending to the extent that the value of the collateral is less than the value of the securities loaned due to the changes in the value of collateral or the loaned securities. The collateral is marked-to-market daily and settled on the next business day. The Funds may receive collateral in the form of cash or other eligible securities, such as a letter of credit issued by a U.S. bank or securities issued or guaranteed by the U.S. government. Securities purchased with cash collateral are subject to the risks inherent in investing in these securities.

There were no securities on loan at September 30, 2023.

h) Repurchase Agreements.  The Funds may invest in repurchase agreements, which are short term investments whereby the Funds acquire ownership of a debt security and the seller agrees to repurchase the security at a future date at a specified price. When entering into repurchase agreements, it is the Funds’ policy that their custodian take possession of the underlying collateral securities, the market value of which, at all times, equals at least 102% of the principal amount of the repurchase transaction. To the extent that any repurchase transaction exceeds one business day, the value of the collateral is marked-to-market to ensure the adequacy of the collateral. If the seller defaults and the market value of the collateral declines or if bankruptcy proceedings are commenced with respect to the seller of the security, realization of the collateral by the Funds may be delayed or limited. The information required to be disclosed by FASB Accounting Standards Update No. 2011-11 for the Funds’ investments in repurchase agreements at September 30, 2023, including the fair value of the repurchase agreement and the amount of collateral, can be found in each respective Fund’s Portfolio of Investments.

i) Master Limited Partnerships.  The Funds may invest in master limited partnerships (MLPs). MLPs are limited partnerships or limited liability companies, whose partnership units or limited liability interests are listed and traded on a U.S. securities exchange, and are treated as publicly traded partnerships for federal income tax purposes. To qualify to be treated as a partnership for tax purposes, an MLP must receive at least 90% of its income from qualifying sources as set forth in Section 7704(d) of the Internal Revenue Code of 1986, as amended. These qualifying sources include interest, dividend, real property rent, gain from sale or other disposition of real property and income from activities such as the exploration, development, mining, production, processing, refining, transportation, storage and marketing of mineral or natural resources.

j) Special Purpose Acquisition Company.  The Funds may acquire an interest in a special purpose acquisition company (SPAC) in an initial public offering (IPO), via a private placement or a secondary market transaction. A SPAC is typically a publicly traded company that raises investment capital via an IPO for the purpose of acquiring the equity securities of one or more existing companies via merger, combination, acquisition or other similar transactions. To the extent the SPAC is invested in cash or similar securities, this may negatively affect a Fund’s performance if the Fund is invested in the SPAC during such period. There is no guarantee that the SPACs will complete an acquisition or that any acquisitions that are completed will be profitable. Some SPACs may pursue acquisitions only within certain industries or regions, which may

37

Baron Funds September 30, 2023

NOTES TO FINANCIAL STATEMENTS (Continued)

2. SIGNIFICANT ACCOUNTING POLICIES AND INVESTMENT RISKS (Continued)

increase the volatility of their prices. These transactions will require the approval of the respective shareholders and are subject to other customary closing conditions, including the receipt of certain regulatory approvals. If these conditions are not met, the SPAC’s acquisition may not close and, to the extent a Fund had committed to participate in a private placement (i.e., PIPE transaction, defined below), the Fund will no longer be obligated to fulfill its commitment.

k) Private Investment in Public Equity.  The Funds may acquire equity securities of an issuer that are issued through a private investment in public equity (PIPE) transaction, including through commitments to purchase securities on a when-issued basis. A Fund will generally earmark an amount of cash or high quality securities equal to the amount of its commitment to purchase the when-issued securities. PIPE transactions typically involve the purchase of securities directly from a publicly traded company in a private placement transaction, including securities issued by a SPAC, typically at a discount to the market price of the company’s securities. There is a risk that if the market price of the securities drops below a set threshold, the company may have to issue additional stock at a significantly reduced price, which may dilute the value of a Fund’s investment. Shares in PIPEs generally are not registered with the SEC until after a certain time period from the date the private sale is completed. This restriction can last an uncertain amount of time and may be many months. Until the public registration process is completed, securities acquired via a PIPE are restricted as to resale and a Fund cannot freely trade the securities. Generally, such restrictions cause these securities to be illiquid during this time. PIPEs may contain provisions that the issuer will pay specified financial penalties to the holder if the issuer does not publicly register the restricted equity securities within a specified period of time, but there is no assurance that the restricted equity securities will be publicly registered, or that the registration will remain in effect.

Publicly traded securities acquired via a PIPE transaction are typically valued at a discount to the market price of an issuer’s common stock and classified as Level 2 or Level 3 in the fair value hierarchy depending on the significance of the unobservable inputs. Discounts are applied due to certain trading restrictions imposed or a lack of marketability preceding the conversion to publicly traded securities. The primary inputs used in determining the discount are the length of the lock-up time period and volatility of the underlying security.

l) Federal and Foreign Income Taxes.  The Trust treats each Fund as a separate entity for federal income tax purposes. Each Fund intends to meet the requirements of the Internal Revenue Code of 1986, as amended, applicable to regulated investment companies, and to distribute to its shareholders substantially all of its net investment income and any net realized capital gains at least annually. None of the Funds will be subject to federal or state income taxes to the extent that they qualify as regulated investment companies and substantially all of their income is distributed.

The Funds may be subject to foreign taxes on income and gains on investments that are accrued based upon the Funds’ understanding of the tax rules and regulations that exist in the countries in which the Funds invest. Foreign governments may also impose taxes or other payments on investments with respect to foreign securities. Such taxes are accrued as applicable.

m) Restricted Securities.  The Funds may invest in securities that are restricted as to public sale in accordance with the Securities Act of 1933. Such assets are valued by the Adviser pursuant to policies and procedures approved by the Board. Refer to Note 6 for additional information.

n) Distributions to Shareholders.  Income and capital gain distributions to shareholders are determined in accordance with income tax regulations which may differ from GAAP. These differences are primarily due to differing treatments for net investment loss, foreign currency gains and losses, non-deductible interest expense, reclassification of distributions, partnership basis adjustments, income from passive foreign investment companies, foreign capital gains tax, late-year loss deferral, post-October loss deferral, and wash sale loss deferral. Income dividends are normally declared and paid annually. During any particular year, net realized gains from investment transactions in excess of available capital loss carryforwards would be taxable to the Funds, if not distributed. The Funds intend to declare and distribute these amounts, at least annually, to shareholders, but may be distributed more frequently. Differences in per share distributions, by class, are generally due to differences in class specific expenses.

o) Commitments and Contingencies.  In the normal course of business, the Funds may enter into contracts and agreements that contain a variety of representations and warranties, which provide general indemnification. The maximum exposure to the Funds under these agreements is unknown, as this would involve future claims that may be made against the Funds that have not yet occurred. However, based on experience, the Funds expect the risk of loss to be remote.

p) Cash and Cash Equivalents.  The Funds consider all short-term liquid investments with a maturity of three months or less when purchased to be cash equivalents.

4. INVESTMENT ADVISORY FEES AND OTHER TRANSACTIONS WITH AFFILIATES

a) Investment Advisory Fees.  The Adviser, a wholly owned subsidiary of Baron Capital Group, Inc. (BCG), serves as investment adviser to the Funds. As compensation for services rendered, the Adviser receives a fee accrued daily as a percentage of each Fund’s average daily net assets and payable monthly, at an annual rate set forth below.

The aforementioned fee waivers and reimbursements, if applicable, are not subject to recoupment by the Adviser.

b) Distribution Fees.  Baron Capital, Inc. (BCI), a wholly owned subsidiary of BCG, is a registered broker-dealer and the distributor of the Funds’ shares. The Funds are authorized to pay BCI a distribution fee payable monthly pursuant to a distribution plan under Rule 12b-1 of the 1940 Act equal to 0.25% per annum of the Retail Shares’ average daily net assets of the respective Funds.

c) Trustee Fees.  Certain Trustees of the Trust are officers of the Adviser and received no direct renumeration in such capacity from the Fund Complex. The Fund Complex pays each Independent Trustee (an Independent Trustee is a Trustee who is not an interested person (as defined in the 1940 Act) of the Fund Complex) annual compensation in addition to reimbursement of out-of-pocket expenses in connection with attendance at meetings of the Board. Specifically, each Independent Trustee receives an annual base compensation of $172,000 with the lead Independent Trustee receiving an additional $20,000. An additional $48,000 per annum is paid to each Independent Trustee for attendance at the quarterly meetings of the Board. Each member of the Audit Committee receives an additional $10,000 in annual compensation with the Audit Committee Chairperson receiving an additional $10,000.

d) Custody, Fund Accounting and Administration Fees.  The Funds have entered into an agreement with State Street Bank and Trust Company (State Street) to perform custody, accounting and certain administrative services.

e) Cross Trades.  The Funds are permitted to purchase securities from, or sell securities to, other Funds within the Trust, the funds in Baron Select Funds, and other entities advised or subadvised by the Adviser, pursuant to “Cross-Trading Procedures” adopted by the Board. These procedures have been designed to ensure that any cross-trade of securities by the respective Baron Fund from or to another fund/other entity that is or could be considered an affiliate of a Fund under certain limited circumstances by virtue of having a common investment adviser, common officers, or common trustees complies with Rule 17a-7 under the 1940 Act. Further, as defined under these procedures, each cross-trade is effected at the current market price and with no commissions. Pursuant to these procedures, for the year ended September 30, 2023, the Funds engaged in the following cross trades:

	Purchases		Sales		Net Realized Gains (Losses)
Baron Opportunity Fund	$	—	$	2,335,800	$	(791,707	)

¹  An “Affiliated” company (affiliated person as defined in the 1940 Act) is a company in which a Fund held 5% or more of the company’s outstanding voting securities at any time during the year ended September 30, 2023.

² Vail Resorts, Inc. became an affiliated company on June 5, 2023 due to decrease of shares of the registrant’s outstanding common stock.

5. LINE OF CREDIT

The Fund Complex (except Baron Partners Fund), participates in a committed line of credit agreement with State Street to be used for temporary purposes, primarily for financing redemptions. Each fund may borrow up to the lesser of $200 million or the maximum amount each fund may borrow under the 1940 Act, the limitations included in each fund’s prospectus, or any limit or restriction under any law or regulation to which each fund is subject or any agreement to which each fund is a party; provided that the aggregate outstanding principal amount of all loans to any of the funds may not exceed $200 million. Interest is charged to each fund, based on its borrowings, at a rate per annum equal to the higher of the Overnight Bank Funding Rate plus 0.10% or the Federal Funds Effective Rate plus 0.10%; plus a margin of 1.00%. An upfront fee of 0.05% is incurred on the commitment amount and a commitment fee of 0.20% per annum is incurred on the unused portion of the line of credit. Both fees are allocated to the participating funds based on their relative net assets.

During the year ended September 30, 2023, the following Funds had borrowings under the line of credit as follows:

Fund	Average Daily Loan Balance*		Maximum Daily Loan Outstanding		Weighted Average Interest Rate			Number of Days Borrowing Outstanding		Outstanding Balance as of 9/30/2023
Baron Growth Fund	$	53.6 million	$	86.4 million		5.04	%		117	$	—
Baron Opportunity Fund	$	3.7 million	$	4.4 million		5.51	%		5	$	—
Baron Fifth Avenue Fund	$	5.1 million	$	13.5 million		5.30	%		36	$	—

* For the days borrowings were outstanding.

The Adviser believes that the fair value of the liabilities under the line of credit agreement is equivalent to the recorded amount based on its short-term maturity and interest rate, which fluctuates over time. A Fund’s outstanding balance under the line of credit agreement, if any, would be categorized as Level 2 in the fair value hierarchy, which is further discussed in Note 7.

6. RESTRICTED SECURITIES

At September 30, 2023, investments in securities included securities that are restricted and/or illiquid. Restricted securities are often purchased in private placement transactions, are not registered under the Securities Act of 1933, may have contractual restrictions on resale and are valued pursuant to the policies and procedures for fair value pricing approved by the Board. An illiquid investment is any investment that the Funds reasonably expect cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment, as determined pursuant to the provisions of SEC Rule 22e – 4 (the “Liquidity Rule”) governing classification of portfolio securities. The Funds may receive more or less than this valuation in an actual sale and that difference could be material.

7. FAIR VALUE MEASUREMENTS

Fair value is defined by GAAP as the price that the Funds would receive upon selling an investment in a timely transaction to an independent buyer in the principal or most advantageous market for the investment. GAAP provides a three-tier hierarchy to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Inputs refer broadly to the assumptions that market participants would use in pricing the asset or liability. Inputs may be observable or unobservable. Observable inputs are based on market data obtained from sources independent of the Funds. Unobservable inputs are inputs that reflect the Funds’ own assumptions based on the best information available in the circumstances. The three-tier hierarchy of inputs is summarized in the three broad Levels listed below.

• Level 1 — quoted prices in active markets for identical assets or liabilities;

• Level 2 — prices determined using other inputs that are observable either directly or indirectly through corroboration with observable market data (which could include quoted prices for similar assets or liabilities, interest rates, credit risk, etc.);

• Level 3 — prices determined using unobservable inputs when quoted prices or observable inputs are unavailable, such as when there is little or no market activity for an asset or liability (unobservable inputs reflect each Fund’s own assumptions in determining the fair value of assets or liabilities and would be based on the best information available).

The inputs or methodology used for valuing securities are not necessarily an indication of the risk or liquidity associated with investing in those securities. For example, non-U.S. securities, with markets that close hours before the Funds value their holdings, may require revised valuations to more accurately reflect their fair value. Since these values obtained from quoted prices in an active market are adjusted, such securities are reflected as Level 2.

The Funds have procedures to determine the fair value of securities and other financial instruments for which market prices are not readily available or which may not be reliably priced. Under these procedures, the Funds primarily employ a market-based approach that may use related or comparable assets or liabilities, recent transactions, market multiples, book values, and other relevant information for the investment to determine its fair value. The Funds may also use an income-based valuation approach in which the anticipated future cash flows of the investment are discounted to calculate fair value. Discounts may also be applied due to the nature or duration of any restrictions on the disposition of the investments. Due to the inherent uncertainty of valuations of such investments, the fair values may differ significantly from the values that would have been used had an active market existed.

The following is a summary of the inputs used as of September 30, 2023 in valuing the Funds’ investments carried at fair value:

¹  The volatility was calculated as a weighted average of the volatilities of the individual comparable companies. Some companies have a higher weight in the calculation than others.

²  Scenario A represents a Direct Listing/IPO Event, Scenario B represents an Other Sale Event, and Scenario C represents a Liquidation Event.

³  The volatility was calculated as a weighted-average of the volatilities of several groups of comparable companies with different industry focus. Each group’s volatility was calculated as the simple average volatilities of comparable companies in the group.

⁴  The volatility was calculated as a weighted-average of the volatilities of the individual comparable companies and an ETF. Some companies have a higher weight in the calculation than others.

⁵  Scenario A represents an IPO Event, while Scenario B represents a Liquidation/M&A Event.

⁶  The probabilities are associated with a range of potential IPO valuations.

^*  Represents the directional change in the fair value of Level 3 investments that could have resulted from an increase in the corresponding input as of period end. A decrease to the unobservable input would have had the opposite effect. Significant changes in these inputs may have resulted in a significantly higher or lower fair value measurement at period end.

A significant change in the EV/EBITDA multiple ratio may result in a directionally similar significant change in the fair value measurement, while a significant change in the discount for lack of marketability and equity index of comparable companies may not result in a materially higher or lower fair value measurement.

8. INCOME TAXES AND DISTRIBUTIONS TO SHAREHOLDERS

Federal income tax regulations differ from GAAP. Therefore, distributions determined in accordance with tax regulations may differ in amount or character from net investment income and net realized gain for financial reporting purposes. Net investment income (loss) and net realized and unrealized gain (loss) may differ for financial statement and tax purposes due to differing treatments of net investment loss, foreign currency gains and losses, non-deductible interest expense, reclassification of distributions, partnership basis adjustments, income from passive foreign investment companies, late year loss deferral, post-October loss deferral, and wash sale loss deferral. Financial reporting records are adjusted for permanent book/tax differences to reflect tax character. Financial records are not adjusted for temporary differences.

For the year ended September 30, 2023, the Funds recorded the following permanent reclassifications to reflect tax character. Reclassifications between income, gains and

paid-in capital relate primarily to the tax treatment of net investment losses and foreign currency gains and losses. Results of operations and net assets were not affected by

these reclassifications.

¹  For tax purposes, short-term capital gains are considered ordinary income distributions.

The Funds follow the provisions of FASB Codification Section 740 (ASC Section 740) “Accounting for Uncertainty in Income Taxes” which clarifies the accounting for uncertainty in tax positions taken or expected to be taken on a tax return. ASC Section 740 sets forth a threshold for financial statement recognition, measurement and disclosure of tax positions taken or expected to be taken on a tax return. The Funds are required to recognize the tax effects of certain tax positions under a “more likely than not” standard, that based on their technical merits, have more than 50% likelihood of being sustained upon examination. Management has analyzed the tax positions taken on the Funds’ federal income tax returns for all open years (current and prior three years), and has concluded that no provision for federal income tax is required in the Funds’ financial statements. At September 30, 2023, the Funds did not have any uncertain tax benefits that require recognition, de-recognition or disclosure. The Funds’ federal, state and local income and federal excise tax returns for which the applicable statutes of limitations have not expired (current and prior three years) are subject to examination by the Internal Revenue Service and state departments of revenue.

9. RECENT ACCOUNTING PRONOUNCEMENT

In June 2022, the FASB issued Accounting Standards Update No. 2022-03 (ASU 2022-03), “Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions” (Topic 820). ASU 2022-03 clarifies the guidance in Topic 820, related to the measurement of the fair value of an equity security subject to contractual sale restrictions, where it eliminates the need to apply a discount to fair value of these securities, and introduces disclosure requirements related to such equity securities. The guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2023, and allows for early adoption. The Adviser is currently evaluating the implications, if any, of the additional requirements and their impact on the Funds’ financial statements.

10. SUBSEQUENT EVENTS

Management has evaluated events occurring subsequent to the date of the Statements of Assets and Liabilities and through the date of issuance of the financial statements and has determined that there were no subsequent events that required adjustment to or disclosure in the financial statements.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Trustees of Baron Investment Funds Trust and Shareholders of Baron Asset Fund, Baron Growth Fund, Baron Small Cap Fund, Baron Opportunity Fund, Baron Fifth Avenue Growth Fund, Baron Discovery Fund and Baron Durable Advantage Fund

Opinions on the Financial Statements

We have audited the accompanying statements of assets and liabilities, including the portfolios of investments, of Baron Asset Fund, Baron Growth Fund, Baron Small Cap Fund, Baron Opportunity Fund, Baron Fifth Avenue Growth Fund, Baron Discovery Fund and Baron Durable Advantage Fund (constituting the Baron Investment Funds Trust, hereafter collectively referred to as the “Funds”) as of September 30, 2023, the related statements of operations for the year ended September 30, 2023, the statements of changes in net assets for each of the two years in the period ended September 30, 2023, including the related notes, and the financial highlights for each of the five years in the period ended September 30, 2023 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of each of the Funds as of September 30, 2023, the results of each of their operations for the year then ended, the changes in each of their net assets for each of the two years in the period ended September 30, 2023 and each of the financial highlights for each of the five years in the period ended September 30, 2023 in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinions

These financial statements are the responsibility of the Funds’ management. Our responsibility is to express an opinion on the Funds’ financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Funds in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of September 30, 2023 by correspondence with the custodian, transfer agent, portfolio companies and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinions.

STATEMENT REGARDING LIQUIDITY RISK MANAGEMENT PROGRAM

The Trust has adopted a liquidity risk management program (the “LRMP”) pursuant to the requirements of Rule 22e-4 under the 1940 Act, which requires registered open-end funds (other than money market funds) to adopt and implement a written liquidity risk management program that is reasonably designed to assess and manage fund liquidity risk. The rule is designed to promote effective liquidity risk management throughout the open-end fund industry, thereby reducing liquidity risk—i.e., the risk that a fund could not meet requests to redeem shares issued by the fund without significant dilution of remaining investors’ interests in the fund.

Pursuant to the requirements of Rule 22e-4, the LRMP is required to include policies and procedures reasonably designed to incorporate the following elements, and the LRMP complies with these requirements: (1) assessment, management and periodic review of liquidity risk; (2) classification of each Fund’s investments into one of the four liquidity categories in Rule 22e-4; (3) if the Fund does not primarily hold assets that are considered highly liquid investments (cash and other investments reasonably expected to be convertible into cash in current market conditions in three business days or less without the conversion into cash significantly changing the market value of the investment), determination of a “highly liquid investment minimum” (as defined in Rule 22e-4 and in the LRMP, the “HLIM”) and compliance with additional related requirements; (4) prohibition on the acquisition of any “illiquid investment” (as defined in Rule 22e-4) if immediately after the acquisition the Fund would have invested more than 15% of its net assets in illiquid investments; and (5) if the Funds reserve the right to engage in redemptions in-kind, establishment of policies and procedures regarding how and when the Funds will engage in such redemptions in-kind. There have been no material changes to the LRMP since it was initially approved by the Board.

The Board has approved the Adviser to administer the LRMP (the “Program Administrator”). The Program Administrator has delegated its responsibilities to a Liquidity Risk Management Committee (the “LRM Committee”), comprised of a cross-functional group of key representatives from various departments of the Program Administrator, including Operations; Accounting; Legal and Compliance; Trading; and Portfolio and Risk Analytics. In addition, the Trust has contracted with a third party liquidity assessment vendor to support the classification of Fund investments.

Pursuant to the requirements of Rule 22e-4, the Board must review, no less frequently than annually, a written report prepared by the Program Administrator that addresses the operation of the program and assesses its adequacy and effectiveness of implementation, including, if applicable, the operation of the HLIM, and any material changes to the program. The Board received a written report in May 2023 (the “Annual Report”).

The Annual Report states that the Adviser, as the Program Administrator, acting primarily through the LRM Committee, has assessed the operation of the LRMP and believes that the LRMP is adequate and effective in its implementation. The Program Administrator and the LRM Committee initially determined that each Fund primarily holds assets that are highly liquid investments, and the Annual Report states that this determination continues to be maintained so that no Fund needs to maintain a HLIM. In addition, the Annual Report states that, since the LRMP was implemented, no Fund has breached its limit on illiquid investments.

FUND EXPENSES (Unaudited)

As a shareholder of the Funds, you incur ongoing expenses. Ongoing expenses include advisory fees, distribution and service (12b-1) fees and other Fund expenses. The information on this page is intended to help you understand your ongoing costs of investing in the Funds and to compare these costs with the ongoing costs of investing in other mutual funds.

The information in the following table is based on an investment of $1,000 invested on April 1, 2023 and held for the six months ended September 30, 2023.

ACTUAL EXPENSES

The table below titled “Based on Actual Total Return” provides information about actual account values and actual expenses. You may use the information provided in this table, together with the amount you invested, to estimate the expenses that you paid over the period. To estimate the expenses you paid on your account, divide your ending account value by $1,000 (for example, an $8,600 ending account value divided by $1,000 = 8.6), then multiply the result by the number under the heading titled “Expenses Paid During the Period”.

DISCLOSURE REGARDING THE APPROVAL OF THE INVESTMENT ADVISORY AGREEMENTS FOR THE FUNDS BY THE BOARD OF TRUSTEES (Unaudited)

The Board of Trustees (the “Board”) of Baron Investment Funds Trust (the “Trust”) met on May 16, 2023 to discuss the selection of BAMCO, Inc. (the “Adviser”) as the investment adviser and the approval of the investment advisory agreements for Baron Asset Fund, Baron Growth Fund, Baron Small Cap Fund, Baron Opportunity Fund, Baron Fifth Avenue Growth Fund, Baron Discovery Fund, and Baron Durable Advantage Fund (each, a “Fund” and collectively, the “Funds”). The members of the Board who are not “interested persons” (as defined in the Investment Company Act of 1940, as amended) of the Trust (the “Independent Trustees”) met in a separate session to discuss and consider the renewal of the investment advisory agreements for the Funds. Representatives of Broadridge Financial Solutions, Inc. (“Broadridge”), an independent provider of investment company data, provided reports to the Board. The Trustees received a substantial amount of information from the Adviser and from Broadridge, and were advised by independent legal counsel. Based on its evaluation of this and other information, the Board, including a majority of the Independent Trustees, approved the continuation of the investment advisory agreements for the Funds for an additional one-year period.

In reaching its determination, the Board considered various factors that it deemed relevant, including the factors listed below.

1. NATURE, EXTENT AND QUALITY OF SERVICES

The Trustees considered the information provided, including, for many, their experience and knowledge gained from their service as Trustees and their experience generally, including the following, which they had considered in past years and remained, in their thinking, material to their consideration:

• Their confidence in the senior personnel, portfolio management, the financial condition of the Adviser and its affiliates and the Adviser’s available resources;

• The nature, extent and quality of the services provided by the Adviser, including: intensive devotion to research, selection of broker/dealers for Fund portfolio transactions, relationships with and supervision of third party service providers, such as the Funds’ custodian and transfer agent, the quality of shareholder reports, the ability to monitor adherence to investment guidelines and restrictions, the legal, accounting and compliance services provided to the Funds and the support services provided to the Board;

• The Adviser’s investment principles and processes and the historical performance of the Funds as compared to similar funds managed by other advisers and other funds managed by the Adviser over comparable periods;

• The advisory fees and total expense ratios of the Funds and comparisons to similar funds managed by other advisers over comparable periods. They observed that, for most of the Funds, while the advisory fee was comparatively higher, the net operating expenses paid by the Funds (total expense ratio) were within the range of those of the funds in their respective peer groups; and

• Additional services provided by the Adviser.

The Board concluded that the nature, extent and quality of the services the Adviser provides to each Fund, including performance consistent with its investing principles, supported approval of the investment advisory agreement for each Fund.

2. INVESTMENT PERFORMANCE OF THE FUNDS AND THE ADVISER

As part of its consideration of the investment performance of the Funds and the Adviser, the Board took into account the analyses performed by representatives of Broadridge. The Board considered for each Fund, among other information, Broadridge’s comparisons of the expense ratio and contractual advisory fee with those of peer group funds selected by Broadridge and Morningstar category medians. The Board also considered, among other performance information, Broadridge’s comparisons of each Fund’s annualized total return and related risk metrics over one-, three-, five- and ten-year periods, where applicable, against peer group funds and Morningstar category medians. After considering all the information, the Board concluded that the Adviser continued to invest in accordance with its long-standing principles and that each Fund’s performance remained consistent with expectations for the Adviser’s investment style, in light of recent market conditions.

3. COSTS OF SERVICES PROVIDED AND PROFITS TO BE REALIZED BY THE ADVISER

The Board considered comparisons of the advisory fees charged and services provided by the Adviser and its investment adviser affiliate to sub-advised accounts and separately managed accounts. The Board considered that, while the advisory fees for the other clients are the same as, or lower than, the fees for the Funds, the Adviser or its affiliate performs significantly fewer services for those clients compared with those provided by the Adviser to the Funds. The Board also considered a profitability analysis prepared by the Adviser and discussed with the representatives of the Adviser that the Adviser has continued to invest in quality personnel, systems and facilities, and otherwise continued to invest in its business, irrespective of fund flows.

The Board also considered benefits that accrue to the Adviser and its affiliates from their relationship with the Funds. The Board considered the costs of portfolio management, including the types of investments made for the Funds, the personnel and systems necessary for implementation of investment strategies, and the pre-tax profits realized by the Adviser and its affiliates from their relationship with the Funds.

4. ECONOMIES OF SCALE AND BENEFITS TO INVESTORS

The Board considered the extent to which each Fund’s advisory fee reflected economies of scale for the benefit of Fund shareholders, appreciating that the economies of scale analysis is predicated on generally predictable increasing assets and noting the significant fluctuation in assets in recent years. The Board considered that small- and mid-cap investment strategies require more attention by the Adviser than a strategy that involves other types of investing, particularly as asset size increases. The Board considered that the Adviser was continuing to grow and upgrade its staff and invest in its business. The Board members reiterated their intention to continue to consider the extent of economies of scale, asset growth and the Adviser’s plans to invest further to support the Funds.

The Board concluded that the advisory fee for each Fund was supported by the entirety of the presentation and particularly in light of the services provided as discussed at this meeting.

After due consideration of the above-enumerated factors and other factors it deemed relevant, the Board, including a majority of the Independent Trustees, approved the continuance of each Fund’s investment advisory agreement.
