MANAGEMENT’S DISCUSSION OF FUND PERFORMANCE

For the 12-month period ended September 30, 2015, Baron Asset Fund¹ increased 1.81%, while the Russell Midcap Growth Index gained 1.45% and the S&P 500 Index fell 0.61%.

Baron Asset Fund invests primarily in medium-sized growth companies for the long term, using a value-oriented purchase discipline.² 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.

Most U.S. market indexes finished the 12-month period with low-single-digit gains; however, beneath this seemingly tranquil surface, many sectors and capitalization ranges experienced significant volatility. For much of the period, the markets generally increased. Despite the dampening effect of the strong dollar and sagging oil prices, continued low interest rates and the slow but steady improvement in the domestic economy helped drive the market higher. However, in late August, stocks plunged sharply, before partly recovering, and then falling again in late September. The reasons for the market decline included increased uncertainty about the health of the Chinese economy and the potential ramifications this might have on global growth; the continued decline in energy and commodity prices; and the shockwaves from a rapid decline in biotechnology shares, driven by concerns about that industry’s pricing trends.

The Fund’s investments in Information Technology (IT), Health Care, and Financials contributed the most to performance. Energy and Utilities were notable detractors in the period.

IDEXX Laboratories, Inc., was the top contributor to performance during the 12-month period. Shares of this leader in veterinary diagnostics rose on better-than-expected earnings and progress on moving to a direct distribution model in the U.S. We believe organic revenue growth at current levels is sustainable due to recent innovations in IDEXX’s portfolio of diagnostic products, instruments, data management tools, and geographic expansion.

Wynn Resorts Ltd., a casino operator with locations in Macau and Las Vegas, was the largest detractor during the period. Shares declined due to investor concerns over the Chinese government’s anti-corruption campaign and increased visa restrictions, which have caused a drop-off in visitors to Macau and spending at the casinos, especially by VIPs. We exited our position.

We continue to believe that mid-sized growth stocks represent an attractive investment opportunity. The U.S. economy remains among the world’s healthiest, its equity market multiples remain within the range of their long-term historic averages, and interest rates continue to be quite low by historic standards. The ongoing drop in energy prices should generate ongoing corollary benefits for many domestic companies. We believe our diversified portfolio of fast growing, well managed, competitively advantaged businesses will continue to perform well in this environment. There is, of course, no guarantee that this will be the case.

²		Prior to February 15, 2007, the Fund’s strategy was to invest primarily in small- and mid-sized growth companies.

MANAGEMENT’S DISCUSSION OF FUND PERFORMANCE

For the 12-month period ended September 30, 2015, Baron Growth Fund¹ gained 1.27%, while the Russell 2000 Growth Index gained 4.04% and the S&P 500 Index declined 0.61%.

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.

Information Technology, Consumer Discretionary, and Financials were the top contributing sectors in the 12-month period. The Industrials, Energy and Health Care sectors were the top detractors.

The top contributor in the period was Under Armour, Inc. Shares of this manufacturer of athletic apparel increased on continued strong financial results driven by revenue growth and impressive cost management. Under Armour appears to be capitalizing on its brand momentum and positioning the business for future growth as it continues to execute on its goal to become the second largest global sporting goods brand. Additionally, Under Armour expressed confidence in its ability to accelerate its growth as it plans to double in size over the next few years.

The biggest detractor was Targa Resources Corp., the General Partner of Targa Resources Partners, a midstream energy Master Limited Partnership. Share prices fell along with the rest of the sector as a result of depressed oil prices. In addition, Targa’s acquisition of Atlas Pipeline in February 2015, while helping to grow and diversify Targa’s onshore U.S. presence, increased Targa’s sensitivity to commodity prices, and caused the stock to drop further. We exited our position.

We believe that a portfolio of investments diversified among several industries all of which are dependent upon different, non-correlated fundamentals will likely help reduce portfolio volatility. In addition, many of the companies in which the Fund invests have significant recurring revenue, which makes earnings for companies in which we have invested less volatile than the Russell 2000 Growth Index. While we do not try to predict short-term macro developments or current events, we believe conditions remain favorable for the U.S. economy and equity markets.

MANAGEMENT’S DISCUSSION OF FUND PERFORMANCE

For the 12-month period ended September 30, 2015, Baron Small Cap Fund¹ declined 4.32%, while the Russell 2000 Growth Index gained 4.04% and the S&P 500 Index declined 0.61%.

Baron Small Cap Fund invests primarily in classic growth stocks that we believe have significant long-term growth prospects and can be purchased at what we believe are attractive prices because their prospects have not yet been appreciated by investors. We also invest in fallen angels, which are companies that we believe have strong long-term franchises but have disappointed investors with short-term results, creating what we believe is a buying opportunity. A third category of investment is special situations, including spin-offs and recapitalizations, where lack of investor awareness creates opportunities to purchase what we believe are strong businesses at attractive prices.

Health Care and Information Technology investments contributed to performance. Holdings in Energy, Materials, and Consumer Discretionary were the top detractors.

DexCom, Inc. was the top contributor in the 12-month period. Shares of DexCom, which sells a continuous glucose monitoring device for insulin-dependent diabetics, more than doubled in the period. DexCom launched the Share system during the period, which allows others such as parents or spouses to receive the user’s blood glucose data from the user’s handheld device. Strong new patient starts, a ramp up in marketing spending, a rising probability that DexCom’s addressable market will include Medicare patients, and greater visibility on the company’s second generation products also helped boost share price.

The biggest detractor was Targa Resources Corp., the General Partner of Targa Resources Partners, a midstream energy Master Limited Partnership. Targa’s acquisition of Atlas Pipeline in February 2015, while helping to grow and diversify Targa’s onshore U.S. presence, increased Targa’s sensitivity to commodity prices, and caused the stock to drop. We believe energy-risk-off sentiment, combined with tax-loss selling and lowered growth expectations for Targa, sent the stock on a free fall. We believe little of the commodity-sensitive cash flows are priced in the current price, and any recovery in commodity prices will likely have a significant positive impact on the stock.

¹		The indexes are unmanaged. The Russell 3000^® Growth Index measures the performance of those companies classified as growth among the largest 3,000 U.S. companies, the Russell Midcap^® Growth Index measures the performance of medium-sized U.S. companies that are classified as growth and the S&P 500 Index of 500 widely held large cap U.S. companies. The Fund no longer considers the Russell Midcap^® Growth Index an appropriate benchmark index. The Russell Midcap^® Growth Index is included in the table above for comparison purposes for the period before the Fund converted to an all-cap fund. Prior to February 20, 2015, the Fund invested in companies with market capitalizations between $1 billion and $15 billion at the time of purchase. Since then, the Fund may invest in companies of all market capitalizations. The Adviser believes that the Russell 3000^® Growth Index is more representative of the Fund’s current investable universe. The indexes and the Fund are with dividends, which positively impact the performance results.

²		Past performance is not predictive of future performance.

MANAGEMENT’S DISCUSSION OF FUND PERFORMANCE

For the 12-month period ended September 30, 2015, Baron Opportunity Fund¹ declined 2.70%, while the Russell 3000 Growth Index gained 3.21% and the S&P 500 Index declined 0.61%.

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. During the period, we made an important change to the Fund. Prior to February 20, 2015, the Fund invested in companies with market capitalizations between $1 billion and $15 billion at the time of purchase. Since then, the Fund may invest in companies of all market capitalizations. The Adviser believes that the Russell 3000 Growth Index is more representative of the Fund’s current investable universe than the previous benchmark, the Russell Midcap Growth Index.

The Consumer Discretionary and Information Technology sectors contributed to the Fund’s performance during the period. Energy, Utilities, and Health Care were the top sector detractors.

Netflix, Inc. was the top contributor in the period. Netflix is the leading global on-demand video service. Shares rose on strong subscriber additions and a robust subscriber growth outlook. The company is accelerating international growth efforts and investing aggressively in original content. We believe Netflix will benefit from the global demand for online on-demand, high-quality, ad-free content. While short-term fluctuations will likely continue, we believe Netflix may potentially achieve 50 million subscribers domestically and over 100 million subscribers abroad.

Shutterstock, Inc. was the top detractor in the 12-month period. Shutterstock is the leading online provider of royalty-free stock photography to consumers and enterprises. Shares fell on investor concerns around Adobe’s launch of a competitive offering, Adobe Stock. Adobe is attempting to improve its competitive positioning by offering lower prices in certain segments, and by integrating image buying into its proprietary software workflow. Given the increased uncertainty created by the competition from Adobe, coupled with the departure of Shutterstock’s CFO, we exited our position.

We remain focused on finding unique businesses across different segments of the economy that we believe offer long-term secular growth, sustainable competitive advantages, high-quality management teams, and attractive stock prices. We believe that investment returns for stocks are driven by earnings growth, and therefore direct our research towards understanding the drivers of business profit and projecting future profit growth as accurately as we can.

MANAGEMENT’S DISCUSSION OF FUND PERFORMANCE

For the 12-month period ended September 30, 2015, Baron Fifth Avenue Growth Fund¹gained 0.48%, while the Russell 1000 Growth Index gained 3.17% and the S&P 500 Index declined 0.61%.

Baron Fifth Avenue Growth Fund focuses on identifying and investing in what we believe are unique large-sized growth companies with sustainable competitive advantages that we believe have 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. Sector weightings are incidental to portfolio construction, and exposure to any sector is a result of stock selection.

Consumer Discretionary, Health Care, and Financials were the top contributing sectors in the period. The Information Technology, Utilities, and Energy sectors were the top detractors.

Amazon.com, Inc. was the top contributor in the period. Shares of the world’s largest retailer rose due to better-than-anticipated operating margins and guidance. The company also broke out Amazon Web Services margins for the first time, which were meaningfully higher than expected. We believe retail margins will continue to improve as the company focuses on productivity gains. With e-commerce representing less than 10% of global retail sales, we believe the shift to online retailing represents a multi-year growth opportunity from which Amazon should benefit.

SunEdison, Inc. was the biggest detractor. Shares of the world’s largest renewable energy developer declined in the wake of its acquisition of U.S. residential solar developer Vivint Solar, with plans to drop down its solar portfolio to its yieldco TerraForm Power, Inc. Investors questioned aspects of the deal, including its $2.2 billion cost. We believe in the secular renewable energy story and that SunEdison’s large development pipeline will benefit it and its yieldcos. We think the market dislocation is technical and temporary and that SunEdison will resume future growth.

The Fund seeks to manage risk by focusing on business risk (competition, management, regulations), valuation risk (purchase price providing a large enough margin of safety), financial risk (leverage and capital structure), and analysis risk (our assumptions). Our objective is not to predict how markets may perform in a given year. Instead, we aim to create a portfolio of unique companies with different end markets because, in our experience, this is the best way to manage market risk over time.

SECTOR BREAKDOWN AS OF SEPTEMBER 30, 2015^†

MANAGEMENT’S DISCUSSION OF FUND PERFORMANCE

For the 12-month period ended September 30, 2015, Baron Discovery Fund¹ declined 4.71%, while the Russell 2000 Growth Index gained 4.04% and the S&P 500 Index declined 0.61%.

Baron Discovery Fund invests primarily in small-sized U.S. growth companies with market capitalizations up to the weighted median market capitalization of the Russell 2000 Growth Index at reconstitution, or companies with market capitalizations up to $1.5 billion, whichever is larger. The Fund invests for the long term in what we believe are companies with appropriately capitalized, open-ended growth opportunities, exceptional leadership, and sustainable competitive advantages at attractive values.

The Health Care and Consumer Discretionary sectors contributed the most to Fund performance in the 12-month period. The Industrials, Information Technology, and Materials sectors were the top detractors.

Inogen, Inc. was the top contributor in the period. Inogen is the leading provider of portable oxygen concentrators (POC) used by chronic respiratory patients reliant on long term oxygen therapy. Shares rose in response to the favorable conclusion of an internal audit that had delayed the report of year-end results, guidance that exceeded Wall Street consensus expectations, and better-than-expected revenues and earnings. We think the POC market is underpenetrated, Inogen’s products are best-in-class, and its leadership position in the direct-to-consumer market represents a significant competitive advantage.

Amber Road, Inc. was the biggest detractor in the period. The company specializes in trade management software for large global corporations such as Honeywell, GE, and Wal-Mart. It has a unique database of trade regulations and mostly recurring revenues with big margins. Amber walked away from a client who was requesting what would have been highly unprofitable customizations. In addition, closings on two contracts were delayed. Amber lowered guidance and the stock fell. We believe these are one-off, short-term events that do not affect Amber’s long-term growth prospects.

We think the long-term fundamentals of our companies remain strong. We believe the companies we own are high quality, innovative and run by excellent management teams. We are optimistic that they will be significantly bigger next year than they are today and that this growth can continue for years after. There is, of course, no guarantee that this will be the case.

Baron Funds

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, and accordingly follows the investment company accounting and reporting guidance of the Financial Accounting Standards Board (“FASB”) Accounting Standard Codification Topic 946 Financial Services – Investment Companies. The Trust currently offers six 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 and Baron Discovery Fund.

Each Fund offers two classes of shares, Retail Shares and Institutional Shares, which differ only in their ongoing fees, expenses and eligibility requirements. Retail Shares are offered to all investors. Institutional Shares are for investments in the amount of $1 million or more per Fund. Institutional Shares are intended for certain financial intermediaries that offer shares of Baron Funds through fee-based platforms, retirement platforms or other platforms. 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.

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.

2. SIGNIFICANT ACCOUNTING POLICIES

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 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. Events occurring subsequent to the date of the Statements of Assets and Liabilities and through the date of issuance of the financial statements have been evaluated for adjustment to or disclosure in the financial statements.

a) Security Valuation. The Funds’ share prices or net asset values are calculated as of the close of the regular trading session (usually 4 p.m. E.T.) on the New York Stock Exchange (“NYSE”) on any day the NYSE is open. 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 Adviser has a Fair Valuation Committee (the “Committee”) comprised of senior executives, and the Committee reports to the Board every quarter. Factors the Committee may consider when valuing a security include whether a current price is stale, there is recent news, the security is thinly traded, transactions are infrequent or quotations are genuine. There can be no guarantee, however, that a fair valuation used by the Funds on any given day will more accurately reflect the market value of an investment than the closing price of such investment in its market. Debt instruments having a remaining maturity greater than 60 days 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 is determined primarily by obtaining valuations from independent pricing services based on readily available bid quotations or, if quotations are not available, by methods which include various considerations such as yields or prices of securities of comparable quality, coupon, maturity and type; indications as to values from dealers; and general market conditions. Other inputs used by an independent pricing service to value convertible bonds generally include underlying stock data, conversion premiums, listed bond and preferred stock prices and other market information which may include benchmark curves, trade execution data, and sensitivity analysis, when available. Money market instruments held by the Funds with a remaining maturity of 60 days or less are generally valued at amortized cost, which approximates fair value. Open-end investment companies, including securities lending collateral invested in registered investment company money market funds, are valued at their net asset value each day.

Non-U.S. equity securities are valued on the basis of their most recent closing market prices and translated into U.S. dollars at 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 fifteen hours old at 4 p.m. E.T. If the Adviser determines that developments between the close of the foreign markets and 4 p.m. E.T. will, in its judgment, materially affect the value of some or all of the 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 may review 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 an outside pricing service that utilizes a systematic methodology to provide the Adviser with closing market prices and information used for adjusting those prices. The Adviser cannot predict how often it will use closing prices or how often it will adjust those prices. As a means of evaluating its fair value process, the Adviser routinely compares closing market prices, the next day’s opening prices in the same markets, and the adjusted prices. Other mutual funds may adjust the prices of their securities by different amounts.

b) Securities Transactions, Investment Income and Expense Allocation. Securities transactions are recorded on a trade date basis. 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. 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. The amounts may

subsequently be reclassified upon receipt of information from the issuer. The Funds are charged for those expenses of the Trust that are directly attributable to each Fund, such as advisory and custodian fees. Expenses that are not directly attributable to a Fund are typically allocated among the Funds in proportion to their respective net assets.

c) Foreign Currency Translations. Values of assets and liabilities denominated in foreign currencies are translated into U.S. dollars using the price of such currencies at the time the net asset value is determined. 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 that portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held. Such fluctuations are included with the net realized and unrealized gain or loss from investments and foreign currency transactions. 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.

d) 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.

At September 30, 2015, Baron Discovery Fund had securities on loan with values of $1,382,150 and received $1,365,000 of cash collateral, which was subsequently invested in short term investments.

e) 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.

f) 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.

g) 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.

h) 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, reclassification of distributions, partnership basis adjustments, income from passive foreign investment companies and wash sale losses deferred.

i) 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.

j) 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.

3. PURCHASES AND SALES OF SECURITIES

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 payable monthly from Baron Asset Fund, Baron Growth Fund, Baron Small Cap Fund, Baron Opportunity Fund and Baron Discovery Fund equal to 1% per annum of the average daily net assets of the respective Funds. The Adviser receives a fee payable monthly from Baron Fifth Avenue Growth Fund equal to 0.90% per annum for daily net assets under $1 billion, 0.85% per annum for daily net assets greater than $1 billion but less than $2 billion and 0.80% per annum for daily net assets greater than $2 billion. For Baron Opportunity Fund, Baron Fifth Avenue Growth Fund and Baron Discovery Fund, the Adviser has contractually agreed to reduce its fee, to the extent required to limit the net annual operating expense ratio (excluding portfolio transaction costs, interest, dividend and extraordinary expenses) to 1.50%, 1.30% and 1.35% of average daily net assets of the Retail Shares, and 1.25%, 1.05% and 1.10% of average daily net assets of the Institutional Shares, respectively.

b) Distribution Fees. Baron Capital, Inc. (“BCI”), a wholly owned subsidiary of BCG, is a registered limited purpose 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 may be deemed to be affiliated with, or interested persons (as defined by the 1940 Act) of the Funds’ Adviser or of BCI. None of the Trustees so affiliated received compensation for his or her services as a Trustee of the Trust. None of the Funds’ officers received compensation from the Funds for their services as an officer.

d) Fund Accounting and Administration Fees. The Funds have entered into an agreement with State Street Bank and Trust Company (“State Street”) to perform accounting and certain administrative services. State Street is compensated for fund accounting services based on a percentage of the Funds’ net assets, subject to certain minimums plus fixed annual fees for the administrative services.

e) Voluntary Payment. In January 2015, the Adviser made a voluntary payment to Baron Discovery Fund in the amount of $1,000 to compensate the Fund for a loss incurred due to a trade processing error. The impact of this payment increased the Fund’s total return by less than 0.01%. In January 2014, the Adviser made a voluntary payment to Baron Opportunity Fund in the amount of $140,762 to compensate the Fund for a loss incurred due to a trade processing error. The impact of this payment increased the Fund’s total return by 0.03%.

5. LINE OF CREDIT

The Funds, together with other funds in Baron Select Funds Trust (except Baron Partners Fund), participate 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 $100 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 $100 million. Interest is charged to each Fund, based on its borrowings, at a rate per annum equal to the higher of the Overnight Federal Funds Rate or the Overnight LIBOR Rate plus a margin of 1.00%. An upfront fee of 0.05% is incurred on the commitment amount and a commitment fee of 0.15% 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, 2015, Baron Growth Fund and Baron Opportunity Fund had borrowings under the line of credit and incurred interest expense of $12,234 and $3,485, respectively. For the 38 days during which there were borrowings, Baron Growth Fund had an average daily balance on the line of credit of $10.0 million at a weighted average interest rate of 1.18%. For the 27 days during which there were borrowings, Baron Opportunity Fund had an average daily balance on the line of credit of $4.1 million at a weighted average interest rate of 1.14%. At September 30, 2015, Baron Growth had an outstanding loan balance in the amount of $500,000.

6. RESTRICTED SECURITIES

At September 30, 2015, 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. A security may be considered illiquid if it lacks a readily available market or if its valuation has not changed for a certain period of time. The Funds may receive more or less than this valuation in an actual sale and that difference could be material. At September 30, 2015, the Funds held investments in restricted and/or illiquid securities that were valued pursuant to policies and procedures for fair value pricing as follows:

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 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 due to significant movement in the U.S. markets. Since these values are not obtained from quoted prices in an active market, 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.

It is the Fund’s policy to recognize transfers in and transfers out at fair value as of the end of the period.

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) differ for financial statement and tax purposes due to differing treatments of net investment loss, foreign currency gains and losses, reclassification of distributions, partnership basis adjustments, income from passive foreign investment companies and wash sale losses deferred. 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, 2015, 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 loss, foreign currency gains and losses and partnership basis adjustments. 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 percent 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, 2015, 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.

11. DISCLOSURES REGARDING OFFSETTING ASSETS AND LIABILITIES

In December 2011, FASB issued an Accounting Standards Update (“ASU”) related to disclosures about offsetting assets and liabilities in financial statements. This ASU requires an entity to disclose both gross and net information for derivatives, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending transactions that are either offset in the statement of assets and liabilities or subject to an enforceable master netting arrangement or similar agreement. In January 2013, the FASB issued an ASU to clarify the scope of disclosures about offsetting assets and liabilities. The ASU is effective for reporting periods beginning on or after January 1, 2013. The information required to be disclosed by the ASU for the Funds’ investments in repurchase agreements at September 30, 2015, including the fair value of the repurchase agreement and the amount of collateral, can be found in each respective Fund’s Statement of Net Assets. The information required to be disclosed by the ASU for the Funds’ securities lending agreement at September 30, 2015, including the market value of securities on loan and the amount of collateral, can be found in each respective Fund’s Statement of Assets and Liabilities. The Funds did not hold derivatives or participate in securities borrowing activities at September 30, 2015.

12. RECENT ACCOUNTING PRONOUNCEMENT

In June 2014, FASB issued “ASU 2014-11 Transfers & Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures” to improve the financial reporting of repurchase agreements and other similar transactions. The guidance includes expanded disclosure requirements for entities that enter into repurchase agreements or securities lending transactions. The guidance is effective for financial statements with fiscal years beginning on or after December 15, 2014, and interim periods beginning after March 15, 2015. The Adviser is evaluating the impact, if any, of this guidance on the Funds’ financial statement disclosures.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Trustees of
Baron Investment Funds Trust

In our opinion, the accompanying statements of assets and liabilities, including the statements of net assets, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of each of Baron Asset Fund, Baron Growth Fund, Baron Small Cap Fund, Baron Opportunity Fund, Baron Fifth Avenue Growth Fund and Baron Discovery Fund (six of the portfolios constituting Baron Investment Funds Trust, hereafter referred to as the “Funds”) at September 30, 2015, 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 then ended and the financial highlights for each of the periods presented, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Funds’ management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at September 30, 2015 by correspondence with the custodian, brokers, and portfolio companies, provide a reasonable basis for our opinion.

FUND EXPENSES (Unaudited)

As a shareholder of the Funds, you may incur two types of costs: ongoing expenses and transaction costs. Ongoing expenses include advisory fees, distribution and service (12b-1) fees and other Fund expenses. Due to the payment of Rule 12b-1 fees, long-term shareholders may indirectly pay more than the maximum permitted front-end sales charge. 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, 2015 and held for the six months ended September 30, 2015.

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”.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The table below titled “Based on Hypothetical Total Return” provides information about hypothetical account values and hypothetical expenses based on the actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Funds’ actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account values and expenses you paid for the period. You may use the information provided in this table to compare the ongoing costs of investing in the Funds and other funds. To do so, compare the 5% hypothetical example relating to the Funds with the 5% hypothetical examples that appear in the shareholder reports of other funds.

Please note that expenses shown in the table below are meant to highlight your ongoing costs and do not reflect any transactional costs, such as redemption fees, if any. Therefore, the table is useful in comparing ongoing costs only and will not help you determine your relative total costs of owning different mutual funds. In addition, if these transactional costs were included, your costs would have been higher.

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 4, 2015 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 and Baron Discovery Fund, (each, a “Fund” and collectively, the “Funds”). The members of the Board who are not affiliated with the Trust (the “Independent Trustees”) met in a separate session to discuss and consider the renewal of the advisory agreements for the Funds. An independent consultant provided reports to the Board and attended the Board meeting. The Trustees received a substantial amount of information from the Adviser and from the independent consultant, 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 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

As part of their consideration of the nature, extent and quality of services provided by the Adviser, the Independent Trustees relied on the information provided, 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 Adviser’s senior personnel and portfolio management, the financial condition of the Adviser and its affiliates and the Adviser’s available resources;

	•		The nature, quality and the level of long-term performance 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 total expense ratio of the Funds and comparisons to similar funds managed by other advisers over comparable periods;

	•		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; and

	•		Additional services provided by the Adviser.

The Board was provided with information from the Adviser and the independent consultant regarding the fees charged by the Adviser as compared to the fees charged by comparable funds. This information compared various fees and expenses, as well as the total expense ratios, of the Funds against the fees, expenses and total expense ratios of other funds of similar size, character and investment strategies (“comparable funds”). The Board observed that, for most of the Funds, while the management fee was relatively high, the other expenses paid by the Funds generally were relatively low, when compared to their comparable funds. They observed that other expenses were relatively high compared to the comparable funds for Baron Discovery Fund, but noted that this was a newer and smaller fund and that total net expenses did not rank below the third quintile. They concluded that the Funds’ higher management fee was justified given the Adviser’s highly research intensive process and highly disciplined adherence to its process. The Board concluded that the nature, extent and quality of the services provided by the Adviser to each Fund were appropriate and that each Fund was likely to continue to benefit from those services provided under the relevant advisory agreement with the Adviser.

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 and discussed with the independent consultant. The Board considered for each Fund, among other information, the independent consultant’s comparisons of the expense ratio and contractual advisory fee with those of the comparable funds selected by the independent consultant, as noted above. The Board noted that long-term performance for each Fund was generally acceptable compared to its comparable funds. The Board noted that no Fund with performance data covering at least ten years was ranked below the third quintile for the ten-year period, except for Baron Fifth Avenue Growth Fund, which was ranked in the fourth quintile for the ten-year period. The Board also noted that Baron Discovery Fund ranked in the first or second quintile for all applicable periods. For the Funds that underperformed relative to their peers during certain periods, representatives of the Adviser described the reasons for the lower relative performance and, as applicable, the steps the Adviser had taken to improve performance. The Board also considered the independent consultant’s risk-adjusted performance comparisons with comparable funds for Funds that have been in existence for more than three years. The Board also considered comparisons of each Fund’s annualized total return over one-, three-, five- and ten-year periods, where applicable, against expense group and performance universe averages and relevant securities market indices. 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 more recent relative performance was consistent with expectations for the Adviser’s investment style under recent market conditions.

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

The Board considered benefits that accrue to the Adviser and its affiliates from their relationship with the Funds. Representatives of the Adviser said the Board should consider the advisory fee in the context of other fees paid to the Adviser’s affiliates, such as the distribution fee paid to Baron Capital, Inc. and paid out pursuant to the 12b-1 plan.

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 the methodology behind certain expense allocations.

4. ECONOMIES OF SCALE AND BENEFITS TO INVESTORS

The Board considered the extent to which each Fund’s management 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 small size of certain Funds and the significant fluctuation in assets since 2007. The Board considered that, except for Baron Fifth Avenue Growth Fund, the Funds’ fee schedules do not have break points. 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 scrutinize the extent of economies of scale, asset growth and the Adviser’s plans to invest further to support the Funds. The Board concluded that approval of the management fee for each Fund was supportable in light of the services provided as discussed at the meeting, including the Adviser’s investments in resources to support the Funds.

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.
