Report of Independent Registered Public Accounting Firm


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

In planning and performing our audits of the financial statements of Baron
Asset Fund, Baron Growth Fund, Baron Small Cap Fund, Baron Opportunity Fund
and Baron Fifth Avenue Growth Fund (five of the portfolios constituting the
Baron Investment Funds Trust, hereafter referred to as the Funds) as of and
for the year ended September 30, 2013, in accordance with the standards of the
Public Company Accounting Oversight Board (United States), we considered the
Funds internal control over financial reporting, including controls over
safeguarding securities, as a basis for designing our auditing procedures for
the purpose of expressing our opinion on the financial statements and to
comply with the requirements of Form N-SAR, but not for the purpose of
expressing an opinion on the effectiveness of the Funds internal control over
financial reporting.  Accordingly, we do not express an opinion on the
effectiveness of the Funds internal control over financial reporting.

The management of the Funds is responsible for establishing and maintaining
effective internal control over financial reporting.  In fulfilling this
responsibility, estimates and judgments by management are required to assess
the expected benefits and related costs of controls.  A funds internal control
over financial reporting is a process designed to provide reasonable assurance
regarding the reliability of financial reporting and the preparation of
financial statements for external purposes in accordance with generally
accepted accounting principles.  A funds internal control over financial
reporting includes those policies and procedures that (1) pertain to the
maintenance of records that, in reasonable detail, accurately and fairly
reflect the transactions and dispositions of the assets of the fund; (2)
provide reasonable assurance that transactions are recorded as necessary to
permit preparation of financial statements in accordance with generally
accepted accounting principles, and that receipts and expenditures of the
fund are being made only in accordance with authorizations of management and
trustees of the fund; and (3)  provide reasonable assurance regarding
prevention or timely detection of unauthorized acquisition, use or disposition
of a funds assets that could have a material effect on the financial
statements.

Because of its inherent limitations, internal control over financial reporting
may not prevent or detect misstatements.  Also, projections of any evaluation
of effectiveness to future periods are subject to the risk that controls may
become inadequate because of changes in conditions, or that the degree of
compliance with the policies or procedures may deteriorate.

A deficiency in internal control over financial reporting exists when the
design or operation of a control does not allow management or employees, in the
normal course of performing their assigned functions, to prevent or detect
misstatements on a timely basis.  A material weakness is a deficiency, or a
combination of deficiencies, in internal control over financial reporting, such
that there is a reasonable possibility that a material misstatement of the
Funds annual or interim financial statements will not be prevented or detected
on a timely basis.

Our consideration of the Funds internal control over financial reporting was
for the limited purpose described in the first paragraph and would not
necessarily disclose all deficiencies in internal control over financial
reporting that might be material weaknesses under standards established by the
Public Company Accounting Oversight Board (United States).  However, we noted
no deficiencies in the Funds internal control over financial reporting and its
operation, including controls over safeguarding securities, that we consider to
be material weaknesses as defined above as of September 30, 2013.

This report is intended solely for the information and use of management and
the Board of Trustees of Baron Investment Funds Trust and the Securities and
Exchange Commission and is not intended to be and should not be used by anyone
other than these specified parties.

SEPTEMBER 30, 2013 BARON FUNDS
-------------------------------------------------------------------------------
DISCLOSURE REGARDING THE APPROVAL OF THE INVESTMENT ADVISORY AGREEMENTS FOR
BARON ASSET FUND, BARON GROWTH FUND, BARON SMALL CAP FUND, BARON OPPORTUNITY
FUND AND BARON FIFTH AVENUE GROWTH FUND, BY THE BOARD OF TRUSTEES (UNAUDITED)
-------------------------------------------------------------------------------
The Board of Trustees (the Board) of Baron Investment Funds Trust (the
Trust) met on May 7, 2013 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 and Baron Fifth Avenue Growth 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 agreement for the Funds. An independent
consultant provided reports to the Board and attended the Board meeting. The
Board received a substantial amount of information from the Adviser and from
the consultant, and was advised by independent 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. The Trustees considered a broad
scope of information and their experiences, including the following, which they
had considered in past years and remained, in their thinking, as material to
their consideration:

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
they received at the Board meeting, as well as on the information they had
considered in past years. In particular, the Board considered the following:
o Its confidence in the Advisers senior personnel, portfolio management,
the financial condition of the Adviser and its affiliates and the
Advisers available resources;

o 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;

o The Advisers 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;
o The total expense ratio of the Funds and comparisons to similar funds
managed by other advisers over comparable periods: the management fee
was relatively high, but the other expenses paid by the Funds generally
were relatively low, when compared to their peers. In discussing the
higher management fee, the Adviser noted its intense research process
and adherence to its investment style;

o 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

o Any additional services provided by the Adviser.

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 also considered the independent
consultants risk-adjusted performance comparisons with comparable funds and
comparisons of each Funds annualized total return over one-, three-, five- and
ten-year periods, where applicable, against expense group and performance
universe averages. After considering all the information, the Board concluded
that the Adviser continued to invest in accordance with its long-standing
principles and that each Funds more recent relative performance was consistent
with expectations for the Advisers investment style under recent market
conditions.

3. COSTS OF SERVICES PROVIDED AND PROFITS TO BE REALIZED 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 same
fees, expenses and total expense ratios of other funds of similar size,
character and investment strategies.

The Board considered comparisons of the advisory fees charged and services
provided by the Adviser and its investment adviser affiliate to the Funds,
subadvised accounts and separately managed accounts and a profitability
analysis prepared by the Adviser. 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 considered benefits that accrue to 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 Funds management fees reflected
economies of scale for the benefit of Fund shareholders, noting the sharp
decline in assets from their highs in 2007 and appreciating that the economies
of scale analysis is predicated on increasing assets. The Board considered that,
except for Baron Fifth Avenue Growth Fund, the Funds fee schedules do not have
break points. The Board considered that the small- and mid-cap investment
strategies require more attention by the Adviser than a strategy that involves
other types of investing, particularly as the size of the assets under
management increases. The Board considered that the Adviser was continuing to
grow and upgrade its staff and invest in its business even during this recent
period of declining assets and reduced revenues. The Board members reiterated
their intention to continue to scrutinize the extent of economies of scale,
asset growth and the Advisers plans to invest further to support the Funds. The
Board concluded that approval of the management fee for each Fund was
reasonable in light of the services provided as discussed at the meeting,
including the Advisers 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 Funds investment advisory agreement.
The Board of Trustees (the Board) of Baron Investment Funds Trust (the
Trust) met on August 19, 2013 to discuss the selection of BAMCO, Inc. (the
Adviser) as the investment adviser and the approval of the investment advisory
agreement for the Baron Discovery Fund (the Fund). The members of the Board
who are not affiliated with the Adviser (the Independent Trustees) met in a
separate session to discuss and consider the approval of the proposed advisory
agreement for the Fund. The Board received a substantial amount of information
from the Adviser and was advised by independent counsel. Based on its
evaluation of this and other information, the Board, including a majority of
the Independent Trustees, approved the advisory agreement for the Fund for an
initial two-year period. The Trustees considered a broad scope of information
and their experiences, including information presented in connection with the
Board meeting held on May 7, 2013, as well as the following, which they had
considered in past years and remained, in their thinking, as material to their
consideration:

1. NATURE, EXTENT AND QUALITY OF SERVICES

As part of their consideration of the nature, extent and quality of proposed
services to be provided by the Adviser, the Independent Trustees relied on the
information they received at the Board meeting, as well as other information
they received at the Board meeting held on May 7, 2013 and at other times. In
particular, the Board considered the following:

o Its confidence in the Advisers senior personnel, portfolio management,
the financial condition of the Adviser and its affiliates and the
Advisers available resources;

o The nature, quality and the level of long-term performance of the
services provided by the Adviser to the other Baron mutual funds, which
were expected to be provided to the Fund, including: intensive devotion
to research, selection of broker/dealers for portfolio transactions,
relationships with and supervision of third party service providers,
such as the 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 to be
provided to the Fund and the support services provided to the Board;

o The Advisers investment principles and processes and the Board
members general understanding of historical performance of the other
funds the Adviser advises as compared to similar funds managed by other
advisers;

o The anticipated total expense ratio of the Fund. As with the Baron
mutual funds considered at the Board meeting held on May 7, 2013, the
Board understood that the management fee was relatively high. As
before, they concluded that the higher management fee was justified
given the Advisers highly research intensive process and highly
disciplined adherence to its process.

o The costs of portfolio management, including the types of investments
to be made for the Fund and the personnel and systems necessary for
implementation of investment strategies; and

o Any additional services to be provided by the Adviser.
The Board concluded that the nature, extent and quality of the services
to be provided by the Adviser to the Fund were appropriate and that it
would likely benefit from those services to be provided under the
advisory agreement with the Adviser.

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

As part of its consideration of the cost of services to be provided,
the Board examined the fees to be charged by the Adviser as compared to
the fees charged by comparable funds.

The Board also considered the Advisers management fees for other
public pooled investment vehicles for which the Adviser serves as a
sub-adviser and the basis of compensation for separate accounts and
private accounts managed by an affiliated adviser. As described at the
Board meeting held on May 7, 2013, while the fees for the other funds
and accounts are the same as, or lower than, the proposed fees for the
Fund, the Adviser performs only portfolio management services for those
clients and does not provide many of the other services to be provided
to the Fund. The Board discussed and considered those other services,
which include accounting, oversight of service providers, legal,
regulatory, compliance, risk management and Trustee support.

In addition, the Board also considered the financial condition of the
Adviser and its affiliates. Since the Fund is newly formed, had not
commenced operations and the eventual aggregate amount of its assets is
uncertain, the Adviser was not able to provide the Board with specific
information concerning the cost of services to be provided and the
expected profits to be realized by the Adviser and its affiliate from
their relationships with the Fund.

The Board concluded that the proposed management fee was reasonable in
light of the services to be provided.

3. ECONOMIES OF SCALE AND BENEFITS TO INVESTORS

Since the Fund is newly formed, had not commenced operations and the
eventual aggregate amount of the Funds assets is uncertain, the
Adviser was not able to provide the Board with specific information
concerning the extent to which economies of scale would be realized as
the Fund grows and whether fee levels would reflect such economies of
scale, if any. It was agreed that the issue would be revisited no later
than when the Board next reviewed the advisory fee in connection with
the renewal of the advisory agreement for the Fund.

After due consideration, including in executive session, of the
above-enumerated factors, among others, the Board, including a majority
of the Independent Trustees, approved the Funds investment advisory
agreement.
