BBH MONEY MARKET FUND
- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS
December 31, 2006 (unaudited)


1.    Organization and Significant  Accounting  Policies.  BBH Money Market Fund
      (the "Fund") is a separate, diversified series of BBH Trust (the "Trust"),
      which is registered under the Investment  Company Act of 1940, as amended.
      The Trust is an open-end  management  investment  company  organized  as a
      Massachusetts   business  trust  on  June  7,  1983.  The  Fund  commenced
      operations  on December 12, 1983.  The  Declaration  of Trust  permits the
      Trustees to create an unlimited number of series,  each of which may issue
      a separate  class of shares.  The Fund  established  a new class of shares
      designated as "Institutional  Shares".  Institutional  Shares commenced on
      December 19, 2006. Regular Shares and Institutional  Shares have different
      operating  expenses.  The  Trustees  have  authorized  the  issuance of an
      unlimited  number  of  shares  of the Fund  with a par  value of $0.01 per
      share. At December 31, 2006, there were four series of the Trust.

      The Fund invests all of its investable assets in the BBH U.S. Money Market
      Portfolio (the "Portfolio"), a diversified, open-end management investment
      company  having the same  investment  objectives as the Fund. The value of
      such  investment  reflects  the Fund's  proportionate  interest in the net
      assets of the  Portfolio  (approximately  61% at December 31,  2006).  The
      performance  of the Fund is directly  affected by the  performance  of the
      Portfolio.  The  financial  statements  of the  Portfolio,  including  the
      portfolio of investments, are included elsewhere in this report and should
      be read in connection with the Fund's financial statements.

      The Fund's financial statements are prepared in accordance with accounting
      principles  generally  accepted  in the United  States of  America,  which
      require  management to make certain  estimates and assumptions at the date
      of the  financial  statements  and are based,  in part,  on the  following
      accounting policies. Actual results could differ from those estimates.

      A.    Valuation of  Investments.  The Fund records its  investments in the
            Portfolio at fair value.  Valuation of  investments in the Portfolio
            is  discussed  in  Note  1 of the  Portfolio's  Notes  to  Financial
            Statements which are included elsewhere in this report.

      B.    Interest  Income and  Expenses.  The Fund  records  its share of the
            Portfolio's  income and  expenses  each day. In  addition,  the Fund
            accrues its own expenses.

      C.    Federal  Income  Taxes.  Each  series of the Trust is  treated  as a
            separate  entity for federal  income tax purposes.  It is the Fund's
            policy to comply with the  provisions  of the Internal  Revenue Code
            applicable  to  regulated  investment  companies  and to  distribute
            substantially  all  of  its  taxable  income  to  its  shareholders.
            Accordingly, no federal income tax provision is required.

      D.    Dividends and  Distributions  to  Shareholders.  Dividends  from net
            investment   income  are   declared   daily  and  paid   monthly  to
            shareholders.

      E     Accounting   Developments.   In  June  2006,   Financial  Accounting
            Standards Board Interpretation No. 48, Accounting for Uncertainty in
            Income Taxes - an  interpretation of FASB Statement 109 (FIN 48) was
            issued and is effective for fiscal years  beginning  after  December
            15,  2006.  FIN 48 sets forth a threshold  for  financial  statement
            recognition,  measurement  and disclosure of a tax position taken or
            expected to be taken on a tax return.  While not  expected to have a
            material impact on the Fund's financial statements,  management will
            be evaluating  the impact,  if any, the adoption of FIN 48 will have
            on the Funds' net assets and results of operations.

            In September 2006,  Statement of Financial  Accounting Standards No.
            157, Fair Value Measurements (SFAS 157), was issued and is effective
            for fiscal years beginning after November 15, 2007. SFAS 157 defines
            fair value,  establishes a framework  for  measuring  fair value and
            expands  disclosures  about fair value  measurements.  Management is
            currently  evaluating the  implication of SFAS 157. At this time its
            impact  on  the  Fund's  financial   statements  has  not  yet  been
            determined.

2.    Transactions with Affiliates.

      Administrative Fees. The Trust has an administration  agreement with Brown
      Brothers Harriman Trust Company,  LLC ("BBHTC") for which BBHTC receives a
      fee from the Fund  calculated  daily and paid monthly at an annual rate of
      0.095%   of  the   Fund's   average   daily  net   assets.   BBHTC  has  a
      sub-administration  services  agreement  with Federated  Services  Company
      ("FSC") for which FSC  receives  compensation  paid by BBHTC.  For the six
      months  ended   December  31,  2006,   the  Fund  incurred   $709,751  for
      administrative services.

      Shareholder   Servicing  Fees.  The  Trust  has  a  shareholder  servicing
      agreement  with Brown Brothers  Harriman  ("BBH") for which BBH receives a
      fee from the Fund  calculated  daily and paid monthly at an annual rate of
      0.25% of the Fund's  average  daily net assets.  For the six months  ended
      December 31, 2006, the Fund incurred $1,867,766 for shareholder  servicing
      services.

      Accounting  Fees. The Fund has an accounting  agreement with BBH for which
      BBH receives a fee from the Fund  calculated  daily and paid monthly.  For
      the six months  ended  December  31, 2006,  the Fund  incurred  $8,000 for
      accounting services.

      Board of Trustees'  Fees.  Each Trustee  receives an annual fee as well as
      reimbursement for reasonable out-of-pocket expenses from the Fund. For the
      six  months  ended  December  31,  2006,  the Fund  incurred  $63,524  for
      Trustees' fees.

of costs: (1) transaction costs on purchase payments,  reinvested dividends,  or
other  distributions;  and  exchange  fees;  and (2)  ongoing  costs,  including
management  fees; and other Fund expenses.  This Example is intended to help you
understand  your  ongoing  costs (in  dollars) of  investing  in the Fund and to
compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period (July 1, 2006 to December 31, 2006).

ACTUAL EXPENSES

The first line of the table below  provides  information  about  actual  account
values and actual expenses.  You may use information in this line, together with
the amount you invested, to estimate the expenses that you paid over the period.
Simply divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6),  then  multiply  the result by the number in the first
line under the heading  entitled  "Expenses  Paid During the Period" to estimate
the expenses you paid on your account during the period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second  line of the table  below  provides  information  about  hypothetical
account  values and  hypothetical  expenses  based on the Fund's actual  expense
ratio and an assumed rate of return of 5% per year before expenses, which is not
the Fund's actual return.  The hypothetical  account values and expenses may not
be used to estimate  the actual  ending  account  balance or  expenses  you paid
during the period.  You may use this information to compare the ongoing costs of
investing in the Fund and other funds.  To do so,  compare this 5%  hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of other funds.

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

(1)   Expenses  are  equal to the  Fund's  annualized  expense  ratio of  0.52%,
      multiplied  by the average  account  value over the period,  multiplied by
      184/365 (to reflect the one-half year period).

(2)   Assumes  a  return  of  5%  before  expenses.   For  the  purpose  of  the
      calculation,  the applicable  annualized  expense ratio is subtracted from
      the assumed return before expenses.

Approval of Continuation of Investment Advisory Agreement

At a meeting held on December 11, 2006,  the Board of Trustees  (the "Board") of
BBH Trust (the  "Trust")  unanimously  approved  the  renewal of the  Investment
Advisory  Agreement  (the "IA  Agreement")  between the Trust and Brown Brothers
Harriman ("BBH") for an additional  one-year term. The following is a summary of
the factors the Board took into  consideration  in making its  determination  to
approve the renewal of the IA Agreement.

Nature, Extent and Quality of Services Provided by BBH

The Board  noted  that,  under the IA  Agreement  in respect of each Fund,  BBH,
subject  to the  supervision  of the  Board,  is  responsible  for  providing  a
continuous  investment  program and, for each Fund other than the  International
Fund,  makes  purchases and sales of portfolio  securities  consistent  with the
Fund's investment objective and policies

The Board considered the scope and quality of services provided by BBH under the
IA Agreement  and noted that the scope of services  provided  had expanded  over
time, primarily, as a result of regulatory  developments.  The Board noted that,
for example,  BBH is responsible  for maintaining and monitoring its own and, to
varying degrees,  the Funds' compliance  program,  and these compliance programs
have recently been refined and enhanced in light of new regulatory requirements.
The Board considered the quality of the investment research  capabilities of BBH
and the other  resources it has dedicated to performing  services for the Funds.
The Board concluded that, overall,  they were satisfied with the nature,  extent
and quality of services  provided  (and  expected to be provided) to each of the
Funds under the IA Agreement.

Costs of Services Provided and Profitability to BBH

At  the  request  of  the  Board,  BBH  provided   information   concerning  the
profitability of BBH's investment company,  advisory fees and other fees and its
statement  of  condition  for the recent  period and as of  December  31,  2005,
respectively.  The Board also reviewed BBH's  profitability  data for each Fund,
which  also  included  the  effect  of  revenue  generated  by  the  shareholder
servicing,  administration,  custody  and other  fees paid by a Fund.  The Board
noted that most beneficial  owners of the Funds' shares are holding these shares
in the context of an overall investment  management program for which BBH is the
adviser  and for which BBH  charges  an  investment  management  fee.  Since BBH
excludes  the assets in the Funds when  calculating  its  advisory  fees for its
clients,  the  Board  agreed  that  it is  appropriate  in an  analysis  of Fund
profitability  to reduce the advisory  fees for the Funds by the  advisory  fees
that otherwise would have been earned by BBH on the assets involved.

The Board discussed the difficulty of making  comparisons of profitability  from
fund  advisory  contracts  because  comparative  information  is  not  generally
publicly available and is affected by numerous factors,  including the structure
of the  particular  adviser,  the types of funds it manages,  its business  mix,
numerous assumptions  regarding  allocations and the adviser's capital structure
and  cost of  capital.  In  considering  profitability  information,  the  Board
considered  the effect of fall-out  benefits on BBH's  expenses,  as well as the
"revenue  sharing"  arrangements BBH has entered into with certain entities that
distribute  shares of the Funds.  The Board  focused on  profitability  of BBH's
relationships with the Funds before taxes and distribution  expenses.  The Board
concluded  that it was  satisfied  that BBH's  level of  profitability  from its
relationship  with each Fund was not  excessive.

BBH MONEY MARKET FUND
- --------------------------------------------------------------------------------
DISCLOSURE OF ADVISOR SELECTION (continued)
December 31, 2006 (unaudited)


The Board also  considered  the advisory  fees of each Fund in comparison to the
fees of comparable  funds.  The Board recognized that the expense ratios for the
Funds potentially  reflected on BBH's provision of services,  as BBH is directly
the provider of substantial  services and coordinates  services  provided to the
Fund by  others.  The Board  took note of  situations  in which BBH  waived  its
management  fee or  reimbursed a Fund's  expenses.

Fall-Out Benefits

The Board considered that BBH did not allocate the Funds' portfolio transactions
for third party  research,  although it did benefit  from  proprietary  research
received from brokers that execute the Funds' purchases and sales of securities.
The Board recognized that the aggregate amount of commissions  generated by Fund
transactions  was  unlikely to result in the Funds  receiving  from full service
broker dealers substantial discounts on commission rates. The Board received and
reviewed  information  concerning  BBH's  policies  with  respect to  allocating
portfolio brokerage.

The Board also  considered  that BBH receives  shareholder  servicing  fees from
certain funds, and is the Funds' administrator, custodian and securities lending
agent.  The Board  noted that BBH  retained no portion of the 12b-1 fees paid by
the Fund that operated with a plan.

The Board recognized that BBH's  profitability would be somewhat lower if it did
not receive  proprietary  research for commissions or, if it did not receive the
other benefits described above. The Board recognized that most Fund shareholders
were also BBH clients,  and that substantial assets are invested in the Funds as
a result of an overall investment  management  program for the shareholder.  The
Board  noted that the Funds also derive  reputational  and other  benefits  from
their  association  with BBH and their use of the BBH name, which is licensed to
the Funds by BBH. Thus,  the Board did not believe that BBH revenues  associated
with its clients should be fairly regarded as "fallout" benefit from the Funds.

Economies of Scale

The  Board  noted  that  the  Funds'  advisory  fee  schedules  do  not  contain
breakpoints. As a result, if assets increase, the fee rates would not be reduced
on the  incremental  assets.  There may be other economies of scale because many
expenses did not rise (and fall)  proportionally to increases (and decreases) in
total net assets.  The Board noted that BBH had priced the advisory  services in
recognition  of  the  fact  that  it  was  largely  its  own  clients  who  were
shareholders  and,  accordingly,  sought  to  assure  that the cost of  advisory
service and total expenses for each Fund were fair and reasonable. Consequently,
the advisory fees are in the range of institutional separate account fees, which
is to say substantially  below, even taking into account the BBH  administration
fees,  typical  mutual  fund fees.  In  addition,  the Board  noted that BBH had
supported and continued to support certain Funds through fee waivers and expense
reimbursements. Based on information they had been provided over many years, the
Board  observed  that in the mutual fund  industry as a whole,  as well as among
funds similar to the Funds, there appeared to be no uniformity or pattern in the
fees and  asset  levels at which  breakpoints  (if any)  apply.  In light of the
Fund's  current  size and expense  structure,  the Board  concluded  that it was
unnecessary at this time to consider  breakpoints.

Investment Results

The Board considered the investment  results of each of the Funds as compared to
investment  companies  with its peers and with one or more  selected  securities
indices.  In addition to the information  received by the Board for the meeting,
the  Board  received  detailed  performance  information  for each  Fund at each
regular  Board  meeting  during the year.  At the  meeting,  the Board  reviewed
information  showing  performance  of each Fund compared to the peers  generally
over the 1-, 3-, 5- and since  inception  periods  ended  October  31,  2005 and
compared to one or more securities indices over comparable periods.

Advisory Fee Rate

The Board  considered  the advisory fee rate paid by each Fund to BBH. The Board
recognized that it is difficult to make  comparisons of these fees, and combined
advisory and  administration  fees, because there are variations in the services
that are included in the fees paid by other funds.

BBH also manages accounts for institutional  clients with investment  objectives
similar  to  those  of  certain  Funds.  The  fee  rates  payable  by the  BBH's
institutional clients are generally comparable although occasionally lower, than
the rates  paid by the  Funds.  BBH  reviewed  with the  Board  the  significant
differences in the scope of services that BBH provides to institutional  clients
and to the Funds through both the IA and Administration  Agreements (the "Admin.
Agreements"). For example, BBH provides, among other things, officers (including
the  Funds'  Chief   Compliance   Officer  and  officers  to  provide   required
certifications) and administrative services, such as shareholder communications,
and tax compliance, with the attendant costs and exposure to liability. BBH also
coordinates  the  provision  of services to the Funds by  nonaffiliated  service
providers.  These services  normally are not provided to non investment  company
clients,  and fees  charged  to the  Funds  reflect  the  costs and risks of the
additional obligations. The Board also noted that since the Funds are constantly
issuing and redeeming  their shares,  they are more  difficult to manage than an
institutional account, where the assets are relatively stable. Accordingly,  the
Board did not place significant weight on these fee comparisons.

The  following  factors  specific  to BBH Money  Market Fund also were noted and
considered  by the Board in  deciding  to  approve  the  continuation  of the IA
Agreements:

The Trustees reviewed  information  showing  performance of the Fund compared to
other funds in the iMoneyNet  (1st Tier  Retail).  The  comparative  information
showed that the Fund had superior  performance compared to the averages in these
categories over all relevant periods.  The Board also viewed with favor that the
total  expense  ratio  was  substantially  lower  than  the  averages  in  these
categories. The Board also noted that the BBH Money Market Fund had maintained a
stable net asset  value of one dollar at all times.  Taking into  account  these
comparisons  and the other  factors  considered,  the Board  concluded  that the
Fund's investment results over time and expense ratios had been satisfactory.

NOTES TO FINANCIAL STATEMENTS
December 31, 2006 (unaudited)
(expressed in U.S. dollars)


1.    Organization and Accounting Policies. BBH U.S. Money Market Portfolio (the
      "Portfolio")  is registered  under the Investment  Company Act of 1940, as
      amended,  as  a  no  load,  diversified,  open-end  management  investment
      company, which was organized as a trust under the laws of the State of New
      York on June 15, 1993. The Portfolio  commenced  operations on October 31,
      1994. The Declaration of Trust permits the Trustees to create interests in
      the Portfolio.

      The  Portfolio's  financial  statements  are prepared in  accordance  with
      accounting  principles generally accepted in the United States of America,
      which require  management to make certain estimates and assumptions at the
      date of the financial  statements and are based, in part, on the following
      accounting policies. Actual results could differ from those estimates.

      A.    Valuation of  Investments.  The Portfolio  values its investments at
            amortized cost, which approximates  market value. The amortized cost
            method  values a security  at its cost at the time of  purchase  and
            thereafter  assumes  a  constant  amortization  to  maturity  of any
            discount or premium.  The  Portfolio's  use of amortized  cost is in
            compliance with Rule 2a-7 of the Investment Company Act of 1940.

      B.    Investment  Transactions  and Income.  Investment  transactions  are
            accounted for on the trade date.  Realized gains and losses, if any,
            from  investment   transactions  are  determined  on  the  basis  of
            identified  cost.  Interest income consists of interest  accrued and
            discount earned  (including both original issue and market discount)
            and  premium  amortization  on the  investments  of  the  Portfolio,
            accrued ratably to the date of maturity.

      C.    Repurchase  Agreements.  The  Portfolio  may enter  into  repurchase
            agreements  with primary dealers of U.S.  Government  Obligations as
            designated  by the  Federal  Reserve  Bank of New  York.  Repurchase
            agreements are  transactions  in which the Portfolio buys a security
            from a dealer  or bank and  agrees  to sell the  security  back at a
            mutually  agreed upon time and price.  The repurchase  price exceeds
            the sale price, reflecting the Portfolio's return on the transaction
            or  effectively  the  interest  rate  paid  by  the  dealer  to  the
            Portfolio.  This return is  unrelated  to the  interest  rate on the
            underlying  security.  The  Portfolio  will  enter  into  repurchase
            agreements   only  with   banks  and  other   recognized   financial
            institutions, such as securities dealers, deemed creditworthy by the
            Investment Adviser. The Portfolio's  custodian or sub-custodian will
            take possession of the securities subject to repurchase  agreements.
            The Investment  Adviser or  sub-custodian  will monitor the value of
            the  underlying  security  each day to ensure  that the value of the
            security always equals or exceeds the repurchase  price.  Repurchase
            agreements  are  subject  to  credit  risks.  Information  regarding
            repurchase agreements is included in the Portfolio of Investments.

      D.    Federal Income Taxes.  The Portfolio is treated as a partnership for
            federal income tax purposes and its operations are conducted in such
            a way that is it not to be  considered  engaged  in a U.S.  trade or
            business  for U.S.  tax  purposes.  Accordingly,  no  provision  for
            federal  income  taxes  is  necessary.   It  is  intended  that  the
            Portfolio's  assets  will be managed in such way that an investor in
            the  Portfolio  will be able to comply  with the  provisions  of the
            Internal Revenue Code applicable to regulated investment  companies.
            At December 31, 2006, the cost of investments for federal income tax
            purposes  was equal to the  amortized  cost of the  investments  for
            financial statement purposes.

      E.    Accounting   Developments.   In  June  2006,   Financial  Accounting
            Standards Board Interpretation No. 48, Accounting for Uncertainty in
            Income Taxes - an  interpretation of FASB Statement 109 (FIN 48) was
            issued and is effective for fiscal years  beginning  after  December
            15,  2006.  FIN 48 sets forth a threshold  for  financial  statement
            recognition,  measurement  and disclosure of a tax position taken or
            expected to be taken on a tax return.  While not  expected to have a
            material impact on the Portfolio's financial statements,  management
            will be evaluating  the impact,  if any, the adoption of FIN 48 will
            have on the Portfolio's net assets and results of operations.

            In September 2006,  Statement of Financial  Accounting Standards No.
            157, Fair Value Measurements (SFAS 157), was issued and is effective
            for fiscal years beginning after November 15, 2007. SFAS 157 defines
            fair value,  establishes a framework  for  measuring  fair value and
            expands  disclosures  about fair value  measurements.  Management is
            currently  evaluating the  implication of SFAS 157. At this time its
            impact  on  the  Fund's  financial   statements  has  not  yet  been
            determined.

2.    Transactions with Affiliates.

      Investment  Advisory  Fees.  The  Portfolio  has  an  investment  advisory
      agreement  with Brown Brothers  Harriman  ("BBH") for which BBH receives a
      fee from the Fund  calculated  daily and paid monthly at an annual rate of
      0.10% of the Portfolio's  average daily net assets.  BBH has established a
      separately identifiable department ("SID") to provide investment advice to
      mutual  funds.  The SID is  registered  with the  Securities  and Exchange
      Commission  under the Investment  Advisors Act of 1940. For the six months
      ended  December 31, 2006, the Portfolio  incurred  $1,267,544 for advisory
      services.

      Administrative  Fees. The Portfolio has an  administration  agreement with
      Brown Brothers  Harriman  Trust  Company,  LLC ("BBHTC") for which it pays
      BBHTC a fee from the Fund  calculated  daily and paid monthly at an annual
      rate of 0.035% of the  Portfolio's  average daily net assets.  BBHTC has a
      sub-administration  services  agreement  with Federated  Services  Company
      ("FSC") for which FSC  receives  compensation  paid by BBHTC.  For the six
      months ended  December  31,  2006,  the  Portfolio  incurred  $443,641 for
      administrative services.

      Custody  and  Accounting  Fees.  BBH acts as a  custodian  and  receives a
      custody  and  accounting  fee  from  the Fund  calculated  daily  and paid
      monthly. The custody fee is a transaction based fee with an annual minimum
      of $20,000, and the accounting fee is calculated at 0.01% per annum on the
      first $1 billion of net assets and 0.005% per annum on all net assets over
      $1 billion.  For the six months ended  December 31,  2006,  the  Portfolio
      incurred  $226,702 for custody and  accounting  services.  These fees were
      reduced by $68,075 as a result of an expense offset  arrangement  with the
      Portfolio's custodian. In the event that the Portfolio is overdrawn, under
      the  custody  agreement  with BBH,  BBH will make  overnight  loans to the
      Portfolio to cover  overdrafts.  Pursuant to their agreement the Portfolio
      will be charged  interest  based on LIBOR on the day of the overdraft plus
      one percent.  The total  interest paid by the Portfolio for the six months
      ended December 31, 2006 was $13,159.

      Board of Trustees'  Fees.  Each Trustee  receives an annual fee as well as
      reimbursement  for reasonable  out-of-pocket  expenses from the Portfolio.
      For the six months ended December 31, 2006, the Portfolio incurred $42,552
      for the Trustees' fees.

BBH U.S. MONEY MARKET PORTFOLIO
- --------------------------------------------------------------------------------
DISCLOSURE OF FUND EXPENSES
December 31, 2006 (unaudited)
(expressed in U.S. dollars)


EXAMPLE

As a shareholder of BBH Money Market Portfolio (the "Portfolio"),  you may incur
two types of costs:  (1)  transaction  costs on  purchase  payments,  reinvested
dividends,  or other  distributions;  and exchange  fees; and (2) ongoing costs,
including  management  fees;  and other  Portfolio  expenses.  This  Example  is
intended to help you understand  your ongoing costs (in dollars) of investing in
the  Portfolio and to compare these costs with the ongoing costs of investing in
other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the
period and held for the  entire  period  (July 1, 2006 to  December  31,  2006).

ACTUAL  EXPENSES

The first line of the table below  provides  information  about  actual  account
values and actual expenses.  You may use information in this line, together with
the amount you invested, to estimate the expenses that you paid over the period.
Simply divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6),  then  multiply  the result by the number in the first
line under the heading  entitled  "Expenses  Paid During the Period" to estimate
the expenses you paid on your account during the period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second  line of the table  below  provides  information  about  hypothetical
account  values and  hypothetical  expenses  based on the Fund's actual  expense
ratio and an assumed rate of return of 5% per year before expenses, which is not
the Portfolio's actual return. The hypothetical  account values and expenses may
not be used to estimate the actual ending  account  balance or expenses you paid
during the period.  You may use this information to compare the ongoing costs of
investing  in  the  Portfolio  and  other  funds.  To do  so,  compare  this  5%
hypothetical  example  with the 5%  hypothetical  examples  that  appear  in the
shareholder reports of other funds.

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



                                                                                                Expenses Paid

(1)   Expenses are equal to the Portfolio's  annualized  expense ratio of 0.16%,
      multiplied  by the average  account  value over the period,  multiplied by
      184/365 (to reflect the one-half year period).

(2)   Assumes  a  return  of  5%  before  expenses.   For  the  purpose  of  the
      calculation,  the applicable  annualized  expense ratio is subtracted from
      the assumed return before expenses.

Approval of Continuation of Investment Advisory Agreement

At a meeting held on December 11, 2006,  the Board of Trustees  (the "Board") of
BBH  Portfolio  (the  "Portfolio")  unanimously  approved  the  renewal  of  the
Investment  Advisory  Agreement (the "IA  Agreement")  between the Portfolio and
Brown  Brothers  Harriman & Co.  ("BBH") for an additional  one-year  term.  The
following  is a summary  of the  factors  the Board took into  consideration  in
making its determination to approve the renewal of the IA Agreement.

Nature, Extent and Quality of Services Provided by BBH

The Board  noted  that,  under the IA  Agreement  in respect of each Fund,  BBH,
subject  to the  supervision  of the  Board,  is  responsible  for  providing  a
continuous  investment  program and, for each Fund other than the  International
Fund,  makes  purchases and sales of portfolio  securities  consistent  with the
Fund's investment objective and policies.

The Board considered the scope and quality of services provided by BBH under the
IA Agreement  and noted that the scope of services  provided  had expanded  over
time, primarily, as a result of regulatory  developments.  The Board noted that,
for example,  BBH is responsible  for maintaining and monitoring its own and, to
varying degrees,  the Funds' compliance  program,  and these compliance programs
have recently been refined and enhanced in light of new regulatory requirements.
The Board considered the quality of the investment research  capabilities of BBH
and the other  resources it has dedicated to performing  services for the Funds.
The Board concluded that, overall,  they were satisfied with the nature,  extent
and quality of services  provided  (and  expected to be provided) to each of the
Funds under the IA Agreement.

Costs of Services Provided and Profitability to BBH

At  the  request  of  the  Board,  BBH  provided   information   concerning  the
profitability of BBH's investment company,  advisory fees and other fees and its
statement  of  condition  for the recent  period and as of  December  31,  2005,
respectively.  The Board also reviewed BBH's  profitability  data for each Fund,
which  also  included  the  effect  of  revenue  generated  by  the  shareholder
servicing,  administration,  custody  and other  fees paid by a Fund.  The Board
noted that most beneficial  owners of the Funds' shares are holding these shares
in the context of an overall investment  management program for which BBH is the
adviser  and for which BBH  charges  an  investment  management  fee.  Since BBH
excludes  the assets in the Funds when  calculating  its  advisory  fees for its
clients,  the  Board  agreed  that  it is  appropriate  in an  analysis  of Fund
profitability  to reduce the advisory  fees for the Funds by the  advisory  fees
that otherwise would have been earned by BBH on the assets involved.

The Board discussed the difficulty of making  comparisons of profitability  from
fund  advisory  contracts  because  comparative  information  is  not  generally
publicly available and is affected by numerous factors,  including the structure
of the  particular  adviser,  the types of funds it manages,  its business  mix,
numerous assumptions  regarding  allocations and the adviser's capital structure
and  cost of  capital.  In  considering  profitability  information,  the  Board
considered  the effect of fall-out  benefits on BBH's  expenses,  as well as the
"revenue  sharing"  arrangements BBH has entered into with certain entities that
distribute  shares of the Funds.  The Board  focused on  profitability  of BBH's
relationships with the Funds before taxes and distribution  expenses.  The Board
concluded  that it was  satisfied  that BBH's  level of  profitability  from its
relationship  with each Fund was not  excessive.

BBH U.S. MONEY MARKET PORTFOLIO
DISCLOSURE OF ADVISOR SELECTION (continued)
December 31, 2006 (unaudited)

The Board also  considered  the advisory  fees of each Fund in comparison to the
fees of comparable  funds.  The Board recognized that the expense ratios for the
Funds potentially  reflected on BBH's provision of services,  as BBH is directly
the provider of substantial  services and coordinates  services  provided to the
Fund by  others.  The Board  took note of  situations  in which BBH  waived  its
management  fee or  reimbursed a Fund's  expenses.

Fall-Out Benefits

The Board considered that BBH did not allocate the Funds' portfolio transactions
for third party  research,  although it did benefit  from  proprietary  research
received from brokers that execute the Funds' purchases and sales of securities.
The Board recognized that the aggregate amount of commissions  generated by Fund
transactions  was  unlikely to result in the Funds  receiving  from full service
broker dealers substantial discounts on commission rates. The Board received and
reviewed  information  concerning  BBH's  policies  with  respect to  allocating
portfolio brokerage.

The Board also  considered  that BBH receives  shareholder  servicing  fees from
certain funds, and is the Funds' administrator, custodian and securities lending
agent.  The Board noted that BBH retained no portion of the 12b-1 fees paid by a
Fund that operated with a plan.

The Board recognized that BBH's  profitability would be somewhat lower if it did
not receive  proprietary  research for commissions or, if it did not receive the
other benefits described above. The Board recognized that most Fund shareholders
were also BBH clients,  and that substantial assets are invested in the Funds as
a result of an overall investment  management  program for the shareholder.  The
Board  noted that the Funds also derive  reputational  and other  benefits  from
their  association  with BBH and their use of the BBH name, which is licensed to
the Funds by BBH. Thus,  the Board did not believe that BBH revenues  associated
with its clients should be fairly regarded as "fallout" benefit from the Funds.

Economies of Scale

The  Board  noted  that  the  Funds'  advisory  fee  schedules  do  not  contain
breakpoints. As a result, if assets increase, the fee rates would not be reduced
on the  incremental  assets.  There may be other economies of scale because many
expenses did not rise (and fall)  proportionally to increases (and decreases) in
total net assets.  The Board noted that BBH had priced the advisory  services in
recognition  of  the  fact  that  it  was  largely  its  own  clients  who  were
shareholders  and,  accordingly,  sought  to  assure  that the cost of  advisory
service and total expenses for each Fund were fair and reasonable. Consequently,
the advisory fees are in the range of institutional separate account fees, which
is to say substantially  below, even taking into account the BBH  administration
fees,  typical  mutual  fund fees.  In  addition,  the Board  noted that BBH had
supported and continued to support certain Funds through fee waivers and expense
reimbursements. Based on information they had been provided over many years, the
Board  observed  that in the mutual fund  industry as a whole,  as well as among
funds similar to the Funds, there appeared to be no uniformity or pattern in the
fees and  asset  levels at which  breakpoints  (if any)  apply.  In light of the
Fund's  current  size and expense  structure,  the Board  concluded  that it was
unnecessary at this time to consider  breakpoints.

Investment Results

The Board considered the investment  results of each of the Funds as compared to
investment  companies  with its peers and with one or more  selected  securities
indices.  In addition to the information  received by the Board for the meeting,
the  Board  received  detailed  performance  information  for each  Fund at each
regular  Board  meeting  during the year.  At the  meeting,  the Board  reviewed
information  showing  performance  of each Fund compared to the peers  generally
over the 1-, 3-, 5- and since  inception  periods  ended  October  31,  2005 and
compared to one or more securities indices over comparable periods.

Advisory Fee Rate

The Board considered the advisory fee rate paid by each Fund to BBH. The Board
recognized that it is difficult to make comparisons of these fees, and combined
advisory and administration fees, because there are variations in the services
that are included in the fees paid by other funds.

BBH also manages accounts for institutional  clients with investment  objectives
similar  to  those  of  certain  Funds.  The  fee  rates  payable  by the  BBH's
institutional clients are generally comparable although occasionally lower, than
the rates  paid by the  Funds.  BBH  reviewed  with the  Board  the  significant
differences in the scope of services that BBH provides to institutional  clients
and to the Funds through both the IA and Administration  Agreements (the "Admin.
Agreements"). For example, BBH provides, among other things, officers (including
the  Funds'  Chief   Compliance   Officer  and  officers  to  provide   required
certifications) and administrative services, such as shareholder communications,
and tax compliance, with the attendant costs and exposure to liability. BBH also
coordinates  the  provision  of services to the Funds by  nonaffiliated  service
providers.  These services  normally are not provided to non investment  company
clients,  and fees  charged  to the  Funds  reflect  the  costs and risks of the
additional obligations. The Board also noted that since the Funds are constantly
issuing and redeeming  their shares,  they are more  difficult to manage than an
institutional account, where the assets are relatively stable. Accordingly,  the
Board did not place significant weight on these fee comparisons.

The following  factors  specific to BBH U.S.  Money Market  Portfolio  also were
noted and considered by the Board in deciding to approve the continuation of the
IA Agreements:

The Trustees reviewed  information showing performance of the Portfolio compared
to other  funds in the  iMoneyNet  (1st  Tier  Institutional).  The  comparative
information showed that the Portfolio had superior  performance  compared to the
averages in these categories over all relevant periods. The Trustees also viewed
with  favor  that the total  expense  ratio  was  substantially  lower  than the
averages in these  categories.  The Trustees also noted that the BBH U.S.  Money
Market  Portfolio  had  maintained a stable net asset value of one dollar at all
times.  Taking into account these comparisons and the other factors  considered,
the Trustees  concluded that the  Portfolio's  investment  results over time and
expense ratios had been satisfactory.

FINANCIAL STATEMENT DECEMBER 31, 2006                                          7



BBH U.S. TREASURY MONEY FUND
- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS
December 31, 2006 (unaudited)


1. Organization and Significant  Accounting  Policies.  BBH U.S.  Treasury Money
   Fund (the  "Fund")  is a  separate,  diversified  series  of BBH  Trust  (the
   "Trust"),  which is registered  under the Investment  Company Act of 1940, as
   amended. The Trust is an open-end management  investment company organized as
   a Massachusetts business trust on June 7, 1983. The Fund commenced operations
   on March 12, 1991. The Declaration of Trust permits the Trustees to create an
   unlimited  number of  series,  each of which may  issue a  separate  class of
   shares.  The Trustees have authorized the issuance of an unlimited  number of
   shares of the Fund with a par value of $0.01 per share. At December 31, 2006,
   there were four series of the Trust.

   The Fund's  financial  statements are prepared in accordance  with accounting
   principles generally accepted in the United States of America,  which require
   management  to make  certain  estimates  and  assumptions  at the date of the
   financial  statements  and are based,  in part, on the  following  accounting
   policies. Actual results could differ from those estimates.

   A. Valuation of  Investments.  The Fund values its  investments  at amortized
      cost, which approximates  market value. The amortized cost method values a
      security  at its cost at the time of  purchase  and  thereafter  assumes a
      constant  amortization to maturity of any discount or premium.  The Fund's
      use of amortized  cost is in compliance  with Rule 2a-7 of the  Investment
      Company Act of 1940.

   B. Investment Transactions and Income.  Investment transactions are accounted
      for on the trade date.  Realized gains and losses, if any, from investment
      transactions  are  determined  on the basis of identified  cost.  Interest
      income consists of interest  accrued and discount  earned  (including both
      original  issue and  market  discount)  and  premium  amortization  on the
      investments of the Fund, accrued ratably to the date of maturity.

   C. Federal  Income  Taxes.  Each series of the Trust is treated as a separate
      entity for federal income tax purposes.  It is the Fund's policy to comply
      with the provisions of the Internal  Revenue Code  applicable to regulated
      investment  companies and to distribute  substantially  all of its taxable
      income to its shareholders.  Accordingly,  no federal income tax provision
      is required.  At December 31, 2006,  the cost of  investments  for federal
      income tax purposes was equal to the  amortized  cost of  investments  for
      financial statement purposes.

   D. Dividends and Distributions to Shareholders. Dividends from net investment
      income are declared daily and paid monthly to shareholders.

   E. Accounting  Developments.  In June 2006,  Financial  Accounting  Standards
      Board  Interpretation No. 48, Accounting for Uncertainty in Income Taxes -
      an  interpretation  of FASB  Statement  109  (FIN  48) was  issued  and is
      effective for fiscal years  beginning after December 15, 2006. FIN 48 sets
      forth a threshold for financial  statement  recognition,  measurement  and
      disclosure of a tax position taken

      or  expected  to be taken on a tax  return.  While not  expected to have a
      material  impact on the Fund's  financial  statements,  management will be
      evaluating  the impact,  if any,  the  adoption of FIN 48 will have on the
      Funds' net assets and results of operations.

      In September 2006,  Statement of Financial  Accounting  Standards No. 157,
      Fair Value Measurements (SFAS 157), was issued and is effective for fiscal
      years  beginning  after  November 15,  2007.  SFAS 157 defines fair value,
      establishes a framework for measuring  fair value and expands  disclosures
      about fair value  measurements.  Management  is currently  evaluating  the
      implication  of SFAS 157. At this time its impact on the Fund's  financial
      statements has not yet been determined.

2. Transactions with Affiliates.

   Investment Advisory Fees. The Trust has an investment advisory agreement with
   Brown  Brothers  Harriman  ("BBH") for which BBH receives a fee from the Fund
   calculated  daily and paid  monthly at an annual  rate of 0.15% of the Fund's
   average  daily net assets.  BBH has  established  a  separately  identifiable
   department  ("SID") to provide  investment advice to mutual funds. The SID is
   registered with the Securities and Exchange  Commission  under the Investment
   Advisors Act of 1940.  For the six months ended  December 31, 2006,  the Fund
   incurred $72,251 for advisory services.

   Administrative  Fees.  The Trust has an  administration  agreement with Brown
   Brothers Harriman Trust Company, LLC ("BBHTC") for which BBHTC receives a fee
   from the Fund calculated daily and paid monthly at an annual rate of 0.10% of
   the Fund's average daily net assets. BBHTC has a sub-administration  services
   agreement  with  Federated  Services  Company  ("FSC") for which FSC receives
   compensation  paid by BBHTC.  For the six months ended December 31, 2006, the
   Fund incurred $48,167 for administrative services.

   Shareholder  Servicing Fees. The Trust has a shareholder  servicing agreement
   with BBH for which BBH receives a fee from the Fund calculated daily and paid
   monthly at an annual rate of 0.225% of the Fund's  average  daily net assets.
   For the six months ended  December 31, 2006,  the Fund incurred  $108,376 for
   shareholder servicing services.

   Custody and  Accounting  Fees. BBH acts as a custodian and receives a custody
   and  accounting  fee from the Fund  calculated  daily and paid  monthly.  The
   custody fee is a transaction based fee with an annual minimum of $20,000, and
   the  accounting  fee is calculated at 0.01% per annum on the first $1 billion
   of net assets and 0.005% per annum on all net assets over $1 billion. For the
   six months ended December 31, 2006, the Fund incurred $29,304 for custody and
   accounting  services.  These  fees were  reduced  by $2,584 as a result of an
   expense offset  arrangement with the Fund's custodian.  In the event that the
   Fund is  overdrawn,  under the  custody  agreement  with  BBH,  BBH will make

   loans to the Fund to cover  overdrafts.  Pursuant to their agreement the Fund
   will be  charged  interest  based on LIBOR on the day of  overdraft  plus one
   percent.  The  total  interest  paid by the  Fund  for the six  months  ended
   December 31, 2006 was $8,374.

   Board of  Trustees'  Fees.  Each  Trustee  receives  an annual fee as well as
   reimbursement  for reasonable  out-of-pocket  expenses from the Fund. For the
   six months ended  December 31, 2006,  the Fund incurred  $5,612 for Trustees'
   fees.

including management fees; and other Fund expenses.  This Example is intended to
help you understand your ongoing costs (in dollars) of investing in the Fund and
to compare  these  costs with the ongoing  costs of  investing  in other  mutual
funds.

The Example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period (July 1, 2006 to December 31, 2006).

ACTUAL EXPENSES

The first line of the table below  provides  information  about  actual  account
values and actual expenses.  You may use information in this line, together with
the amount you invested, to estimate the expenses that you paid over the period.
Simply divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6),  then  multiply  the result by the number in the first
line under the heading  entitled  "Expenses  Paid During the Period" to estimate
the expenses you paid on your account during the period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second  line of the table  below  provides  information  about  hypothetical
account  values and  hypothetical  expenses  based on the Fund's actual  expense
ratio and an assumed rate of return of 5% per year before expenses, which is not
the Fund's actual return.  The hypothetical  account values and expenses may not
be used to estimate  the actual  ending  account  balance or  expenses  you paid
during the period.  You may use this information to compare the ongoing costs of
investing in the Fund and other funds.  To do so,  compare this 5%  hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of other funds.

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

                                                               Expenses Paid

(1)   Expenses  are  equal to the  Fund's  annualized  expense  ratio of  0.63%,
      multiplied  by the average  account  value over the period,  multiplied by
      184/365 (to reflect the one-half year period).

(2)   Assumes  a  return  of  5%  before  expenses.   For  the  purpose  of  the
      calculation,  the applicable  annualized  expense ratio is subtracted from
      the  assumed  return  before  expenses.

DISCLOSURE OF ADVISOR SELECTION

Approval of Continuation of Investment Advisory Agreement

At a meeting held on December 11, 2006,  the Board of Trustees  (the "Board") of
BBH Trust,  Inc.  (the  "Corporation")  unanimously  approved the renewal of the
Investment  Advisory Agreement (the "IA Agreement")  between the Corporation and
Brown  Brothers  Harriman & Co.  ("BBH") for an additional  one-year  term.  The
following  is a summary  of the  factors  the Board took into  consideration  in
making its determination to approve the renewal of the IA Agreement.

Nature, Extent and Quality of Services Provided by BBH

The Board  noted  that,  under the IA  Agreement  in respect of each Fund,  BBH,
subject  to the  supervision  of the  Board,  is  responsible  for  providing  a
continuous  investment  program and, for each Fund other than the  International
Fund,  makes  purchases and sales of portfolio  securities  consistent  with the
Fund's investment objective and policies.

The Board considered the scope and quality of services provided by BBH under the
IA Agreement  and noted that the scope of services  provided  had expanded  over
time, primarily, as a result of regulatory  developments.  The Board noted that,
for example,  BBH is responsible  for maintaining and monitoring its own and, to
varying degrees,  the Funds' compliance  program,  and these compliance programs
have recently been refined and enhanced in light of new regulatory requirements.
The Board considered the quality of the investment research  capabilities of BBH
and the other  resources it has dedicated to performing  services for the Funds.
The Board concluded that, overall,  they were satisfied with the nature,  extent
and quality of services  provided  (and  expected to be provided) to each of the
Funds under the IA Agreement.

Costs of Services Provided and Profitability to BBH

At  the  request  of  the  Board,  BBH  provided   information   concerning  the
profitability of BBH's investment company,  advisory fees and other fees and its
statement  of  condition  for the recent  period and as of  December  31,  2005,
respectively.  The Board also reviewed BBH's  profitability  data for each Fund,
which  also  included  the  effect  of  revenue  generated  by  the  shareholder
servicing,  administration,  custody  and other  fees paid by a Fund.  The Board
noted that most beneficial  owners of the Funds' shares are holding these shares
in the context of an overall investment  management program for which BBH is the
adviser  and for which BBH  charges  an  investment  management  fee.  Since BBH
excludes  the assets in the Funds when  calculating  its  advisory  fees for its
clients,  the  Board  agreed  that  it is  appropriate  in an  analysis  of Fund
profitability  to reduce the advisory  fees for the Funds by the  advisory  fees
that otherwise would have been earned by BBH on the assets involved.

The Board discussed the difficulty of making  comparisons of profitability  from
fund  advisory  contracts  because  comparative  information  is  not  generally
publicly available and is affected by numerous factors,  including the structure
of the  particular  adviser,  the types of funds it manages,  its business  mix,
numerous assumptions  regarding  allocations and the adviser's capital structure
and  cost of  capital.  In  considering  profitability  information,  the  Board
considered the effect of fall-out benefits on BBH's expenses, as well


12



BBH U.S. TREASURY MONEY FUND
- --------------------------------------------------------------------------------
DISCLOSURE OF ADVISOR SELECTION (continued)
December 31, 2006 (unaudited)


as the "revenue sharing" arrangements BBH has entered into with certain entities
that distribute shares of the Funds. The Board focused on profitability of BBH's
relationships with the Funds before taxes and distribution  expenses.  The Board
concluded  that it was  satisfied  that BBH's  level of  profitability  from its
relationship with each Fund was not excessive.

The Board also  considered  the advisory  fees of each Fund in comparison to the
fees of comparable  funds.  The Board recognized that the expense ratios for the
Funds potentially  reflected on BBH's provision of services,  as BBH is directly
the provider of substantial  services and coordinates  services  provided to the
Fund by  others.  The Board  took note of  situations  in which BBH  waived  its
management fee or reimbursed a Fund's expenses.

Fall-Out Benefits

The Board considered that BBH did not allocate the Funds' portfolio transactions
for third party  research,  although it did benefit  from  proprietary  research
received from brokers that execute the Funds' purchases and sales of securities.
The Board recognized that the aggregate amount of commissions  generated by Fund
transactions  was  unlikely to result in the Funds  receiving  from full service
broker dealers substantial discounts on commission rates. The Board received and
reviewed  information  concerning  BBH's  policies  with  respect to  allocating
portfolio brokerage.

The Board also  considered  that BBH receives  shareholder  servicing  fees from
certain funds, and is the Funds' administrator, custodian and securities lending
agent.  The Board  noted that BBH  retained no portion of the 12b-1 fees paid by
the Fund that operated with a plan.

The Board recognized that BBH's  profitability would be somewhat lower if it did
not receive  proprietary  research for commissions or, if it did not receive the
other benefits described above. The Board recognized that most Fund shareholders
were also BBH clients,  and that substantial assets are invested in the Funds as
a result of an overall investment  management  program for the shareholder.  The
Board  noted that the Funds also derive  reputational  and other  benefits  from
their  association  with BBH and their use of the BBH name, which is licensed to
the Funds by BBH. Thus,  the Board did not believe that BBH revenues  associated
with its clients should be fairly regarded as "fallout" benefit from the Funds.

Economies of Scale

The  Board  noted  that  the  Funds'  advisory  fee  schedules  do  not  contain
breakpoints. As a result, if assets increase, the fee rates would not be reduced
on the  incremental  assets.  There may be other economies of scale because many
expenses did not rise (and fall)  proportionally to increases (and decreases) in
total net assets.  The Board noted that BBH had priced the advisory  services in
recognition  of  the  fact  that  it  was  largely  its  own  clients  who  were
shareholders  and,  accordingly,  sought  to  assure  that the cost of  advisory
service and total expenses for each Fund were fair and reasonable. Consequently,
the advisory fees are in the range of institutional separate account fees, which
is to say substantially  below, even taking into account the BBH  administration
fees, typical mutual fund fees. In addition, the Board noted


FINANCIAL STATEMENT DECEMBER 31, 2006                                         13



BBH U.S. TREASURY MONEY FUND
- --------------------------------------------------------------------------------
DISCLOSURE OF ADVISOR SELECTION (continued)

that BBH had  supported  and  continued  to support  certain  Funds  through fee
waivers and expense reimbursements.  Based on information they had been provided
over many years, the Board observed that in the mutual fund industry as a whole,
as well as among funds similar to the Funds,  there appeared to be no uniformity
or pattern in the fees and asset levels at which  breakpoints (if any) apply. In
light of the Fund's current size and expense structure, the Board concluded that
it was unnecessary at this time to consider breakpoints.

Investment Results

The Board considered the investment  results of each of the Funds as compared to
investment  companies  with its peers and with one or more  selected  securities
indices.  In addition to the information  received by the Board for the meeting,
the  Board  received  detailed  performance  information  for each  Fund at each
regular  Board  meeting  during the year.  At the  meeting,  the Board  reviewed
information  showing  performance  of each Fund compared to the peers  generally
over the 1-, 3-, 5- and since  inception  periods  ended  October  31,  2005 and
compared to one or more securities indices over comparable periods.

Advisory Fee Rate

The Board  considered  the advisory fee rate paid by each Fund to BBH. The Board
recognized that it is difficult to make  comparisons of these fees, and combined
advisory and  administration  fees, because there are variations in the services
that are included in the fees paid by other funds.

BBH also manages accounts for institutional  clients with investment  objectives
similar  to  those  of  certain  Funds.  The  fee  rates  payable  by the  BBH's
institutional clients are generally comparable although occasionally lower, than
the rates  paid by the  Funds.  BBH  reviewed  with the  Board  the  significant
differences in the scope of services that BBH provides to institutional  clients
and to the Funds through both the IA and Administration  Agreements (the "Admin.
Agreements"). For example, BBH provides, among other things, officers (including
the  Funds'  Chief   Compliance   Officer  and  officers  to  provide   required
certifications) and administrative services, such as shareholder communications,
and tax compliance, with the attendant costs and exposure to liability. BBH also
coordinates  the  provision  of services to the Funds by  nonaffiliated  service
providers.  These services  normally are not provided to non investment  company
clients,  and fees  charged  to the  Funds  reflect  the  costs and risks of the
additional obligations. The Board also noted that since the Funds are constantly
issuing and redeeming  their shares,  they are more  difficult to manage than an
institutional account, where the assets are relatively stable. Accordingly,  the
Board did not place significant weight on these fee comparisons.

The following  factors specific to BBH U.S.  Treasury Money Fund also were noted
and  considered by the Board in deciding to approve the  continuation  of the IA
Agreements:

The Trustees  considered the 1-, 3- and 5-year  annualized  total returns versus
the iMoneyNet (Treasury Retail). The Trustees noted favorable comparisons versus
that  average  for the  most  recent  periods  and,  in their  view,  immaterial
difference over longer ones.  Moreover,  they had been appropriately  advised by
BBH about its  duration  and  average  weighted  maturity  decisions  during the
relevant  periods and were  satisfied  overall with the  competitiveness  of the
performance.  The  Trustees  also noted with  favor that the  expense  ratio was
substantially  lower than that of the average.  The Trustees also noted that the
Fund had  successfully  maintained a stable net asset value of one dollar at all
times.  Taking into account these comparisons and the other factors  considered,
the  Trustees  concluded  that the Fund's  investment  results over time and its
total expense ratio had been satisfactory.

BBH TAX FREE SHORT/INTERMEDIATE FIXED INCOME FUND
- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS
December 31, 2006 (unaudited)

1.    Organization   and   Significant   Accounting   Policies.   BBH  Tax  Free
      Short/Intermediate   Fixed   Income  Fund  (the  "Fund")  is  a  separate,
      diversified  series of BBH Trust (the "Trust"),  which is registered under
      the Investment  Company Act of 1940, as amended.  The Trust is an open-end
      management investment company organized as a Massachusetts  business trust
      on June 7, 1983.  The Fund  commenced  operations  on July 23,  1992.  The
      Declaration of Trust permits the Trustees to create an unlimited number of
      series,  each of which may issue a separate class of shares.  The Trustees
      have authorized the issuance of an unlimited  number of shares of the Fund
      with a par value of $0.01 per share. At December 31, 2006, there were four
      series of the Trust.

      The Fund's financial statements are prepared in accordance with accounting
      principles  generally  accepted  in the United  States of  America,  which
      require  management to make certain  estimates and assumptions at the date
      of the  financial  statements  and are based,  in part,  on the  following
      accounting policies. Actual results could differ from those estimates.

      A.    Valuation of  Investments.  Bonds and other fixed income  securities
            (other than short-term obligations, but including listed issues) are
            valued on the basis of valuations furnished by pricing services, use
            of which has been approved by the Board of Trustees.  In making such
            valuations,   the  pricing  services  utilize  both  dealer-supplied
            valuations and electronic data processing techniques which take into
            account  appropriate factors such as  institutional-size  trading in
            similar groups of securities, yield, quality, coupon rate, maturity,
            type of  issue,  trading  characteristics  and  other  market  data,
            without  exclusive  reliance  upon  quoted  prices  or  exchange  or
            over-the-counter  prices,  since such  valuations  are  believed  to
            reflect more accurately the fair value of such securities.

            Securities  or other  assets  for which  market  quotations  are not
            readily  available  are  valued  at fair  value in  accordance  with
            procedures  established  by and under the  general  supervision  and
            responsibility of the Trustees.  Short-term investments which mature
            in 60 days or less are valued at amortized cost, which  approximates
            market value.

      B.    Accounting for Investments and Income.  Investment  transactions are
            accounted for on the trade date.  Realized gains and losses, if any,
            from  investment   transactions  are  determined  on  the  basis  of
            identified  cost.  Interest  income is accrued daily and consists of
            interest accrued, discount earned (including both original issue and
            market discount) and premium  amortization on the investments of the
            Fund.  The Fund  invests  primarily  in debt  securities  issued  by
            municipalities. The ability of the issuers of the debt securities to
            meet their obligation may be affected by economic  developments in a
            specific state or  municipality.  Debt  obligations may be placed on
            non-accrual  status and  related  interest  income may be reduced by
            ceasing  current  accruals and writing off interest  receivable when
            the  collection of all or a portion of interest has become  doubtful
            based on constantly applied procedures. A debt obligation is removed
            from non-accrual status when the issuer resumes interest payments or
            when collectibility of interest is reasonable assured.

      C.    Federal Income Taxes. It is the Corporation's  policy to comply with
            the   requirements  of  the  Internal   Revenue  Code  (the  "Code")
            applicable to regulated  investment  companies and to distribute all
            of its taxable income to its shareholders.  Accordingly,  no federal
            income  tax  provision  is  required.  The Fund  files a tax  return
            annually using tax accounting  methods  required under provisions of
            the Code  which may  differ  from  accounting  principles  generally
            accepted in the United  States of America,  the basis on which these
            financial  statements are prepared.  Accordingly,  the amount of net
            investment  income and net realized gain reported on these financial
            statements  may differ  from that  reported on the Fund's tax return
            due  to  certain  book-to-tax  timing  differences  such  as  losses
            deferred due to "wash sale"  transactions and utilization of capital
            loss   carryforwards.   These   differences   result  in   temporary
            over-distributions   for  financial   statement   purposes  and  are
            classified as  distributions  in excess of accumulated  net realized
            gains  or  net  investment  income.   These   distributions  do  not
            constitute   a  return  of  capital.   Permanent   differences   are
            reclassified on the Statement of Assets & Liabilities

            based upon  their tax  classification.  As such,  the  character  of
            distributions to shareholders  reported in the Financial  Highlights
            table  may  differ  from  that  reported  to  shareholders  on  Form
            1099-DIV.

      D.    Dividends and  Distributions  to  Shareholders.  Dividends  from net
            investment income are declared daily and paid monthly. Distributions
            from net capital  gains,  if any, are paid at least annually and are
            recorded on the  ex-dividend  date.  Distributions  paid by the Fund
            from net interest received on tax-exempt bonds are not includable by
            shareholders as gross income for federal income tax purposes because
            the Fund intends to meet certain requirements of the Code applicable
            to regulated  investment companies which will enable the Fund to pay
            tax-exempt interest dividends.

            Capital  Loss  Carryforward.  At June  30,  2006  the fund had a net
            capital loss carryforward of approximately $305,022 which expires as
            follows:

                           June 30, 2014    $305,019
                           June 30, 2013    $      3

      E.    Accounting   Developments.   In  June  2006,   Financial  Accounting
            Standards Board Interpretation No. 48, Accounting for Uncertainty in
            Income Taxes - an  interpretation of FASB Statement 109 (FIN 48) was
            issued and is effective for fiscal years  beginning  after  December
            15,  2006.  FIN 48 sets forth a threshold  for  financial  statement
            recognition,  measurement  and disclosure of a tax position taken or
            expected to be taken on a tax return.  While not  expected to have a
            material impact on the Fund's financial statements,  management will
            be evaluating  the impact,  if any, the adoption of FIN 48 will have
            on the Funds' net assets and results of operations.

            In September 2006,  Statement of Financial  Accounting Standards No.
            157, Fair Value Measurements (SFAS 157), was issued and is effective
            for fiscal years beginning after November 15, 2007. SFAS 157 defines
            fair value,  establishes a framework  for  measuring  fair value and
            expands  disclosures  about fair value  measurements.  Management is
            currently  evaluating the  implication of SFAS 157. At this time its
            impact  on  the  Fund's  financial   statements  has  not  yet  been
            determined.

      Investment  Advisory Fees. The Trust has an investment  advisory agreement
      with Brown Brothers Harriman ("BBH") for which BBH receives a fee from the
      Fund  calculated  daily and paid monthly at an annual rate of 0.25% of the
      Fund's  average  daily  net  assets.  BBH  has  established  a  separately
      identifiable  department  ("SID") to provide  investment  advice to mutual
      funds.  The SID is registered with the Securities and Exchange  Commission
      under  the  Investment  Advisors  Act of 1940.  For the six  months  ended
      December 31, 2006, the Fund incurred $36,568 for advisory services.

      Administrative Fees. The Trust has an administration  agreement with Brown
      Brothers Harriman Trust Company,  LLC ("BBHTC") for which BBHTC receives a
      fee from the Fund  calculated  daily and paid monthly at an annual rate of
      0.15%  of  the   Fund's   average   daily   net   assets.   BBHTC   has  a
      sub-administration  services  agreement  with Federated  Services  Company
      ("FSC") for which FSC  receives  compensation  paid by BBHTC.  For the six
      months  ended   December  31,  2006,   the  Fund   incurred   $21,941  for
      administrative services.

      Shareholder   Servicing  Fees.  The  Trust  has  a  shareholder  servicing
      agreement  with BBH for which BBH receives a fee from the Fund  calculated
      daily and paid  monthly at an annual  rate of 0.25% of the Fund's  average
      daily net assets.  For the six months ended  December  31, 2006,  the Fund
      incurred $36,568 for shareholder servicing services.

      Custody  and  Accounting  Fees.  BBH acts as a  custodian  and  receives a
      custody  and  accounting  fee  from  the Fund  calculated  daily  and paid
      monthly. The custody fee is a transaction based fee with an annual minimum
      of $20,000, and the accounting fee is calculated at 0.04% per annum on the
      first $100 million of net assets, 0.02% per annum on the next $400 million
      of net assets and 0.01% per annum on all net assets over $500 million. For
      the six months  ended  December  31, 2006,  the Fund  incurred  $3,209 for
      custody and  accounting  services.  These fees were reduced by $3,209 as a
      result of an expense offset arrangement with the Fund's custodian.  In the
      event that the Fund is overdrawn,  under the custody  agreement  with BBH,
      BBH will make overnight loans to the Fund to cover overdrafts. Pursuant to
      their  agreement the Fund will be charged  interest  based on LIBOR on the
      day of overdraft plus one percent. The total interest paid by the Fund for
      the six months ended December 31, 2006 was $585.

      Board of Trustees'  Fees.  Each Trustee  receives an annual fee as well as
      reimbursement for reasonable out-of-pocket expenses from the Fund. For the
      six months ended  December 31, 2006,  the Fund  incurred $0 for  Trustees'
      fees.

3.    Investment  Transactions.  For the six months ended December 31, 2006, the
      cost of purchases and the proceeds of sales of investment securities other
      than   short-term   investments   were   $57,421,933   and   $113,920,678,
      respectively.

4.    Share Transactions. Transactions in fund shares were as follows:

5.    Subsequent  Event.  At a meeting  held on October  2,  2006,  the Board of
      Trustees of the Fund  determined  that it was in the best  interest of the
      Fund's shareholders to liquidate the Fund.  Shareholders were given notice
      of this  determination,  along with a request  that  shares of the Fund be
      redeemed before October 31, 2006. At a subsequent meeting held on December
      11,  2006,  the  Board  authorized  the  involuntary   redemption  of  the
      outstanding  shares  of the Fund,  in  complete  liquidation  of the Fund.
      Shareholders  were given notice on January 23, 2007 that on or after March
      26, 2007 the Fund will redeem their shares.

DISCLOSURE OF FUND EXPENSES
December 31, 2006 (unaudited)

EXAMPLE

As a  shareholder  of BBH Tax Free  Short/Intermediate  Fixed  Income  Fund (the
"Fund"),  you may incur two types of costs:  (1)  transaction  costs on purchase
payments,  reinvested dividends, or other distributions;  and exchange fees; and
(2) ongoing costs,  including  management  fees;  and other Fund expenses.  This
Example is intended to help you  understand  your ongoing  costs (in dollars) of
investing  in the Fund and to  compare  these  costs with the  ongoing  costs of
investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period (July 1, 2006 to December 31, 2006).

ACTUAL EXPENSES

The first line of the table below  provides  information  about  actual  account
values and actual expenses.  You may use information in this line, together with
the amount you invested, to estimate the expenses that you paid over the period.
Simply divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6),  then  multiply  the result by the number in the first
line under the heading  entitled  "Expenses  Paid During the Period" to estimate
the expenses you paid on your account during the period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second  line of the table  below  provides  information  about  hypothetical
account  values and  hypothetical  expenses  based on the Fund's actual  expense
ratio and an assumed rate of return of 5% per year before expenses, which is not
the Fund's actual return.  The hypothetical  account values and expenses may not
be used to estimate  the actual  ending  account  balance or  expenses  you paid
during the period.  You may use this information to compare the ongoing costs of
investing in the Fund and other funds.  To do so,  compare this 5%  hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of other funds.

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

                                                               Expenses Paid

Hypothetical(2)            $1,000          $1,021.58               $3.67

- ----------
(1)   Expenses  are  equal to the  Fund's  annualized  expense  ratio of  0.72%,
      multiplied  by the average  account  value over the period,  multiplied by
      184/365 (to reflect the one-half year period).

(2)   Assumes  a  return  of  5%  before  expenses.   For  the  purpose  of  the
      calculation,  the applicable  annualized  expense ratio is subtracted from
      the assumed return before expenses.

DISCLOSURE OF ADVISOR SELECTION
DECEMBER 31, 2006 (UNAUDITED)

Approval of Continuation of Investment Advisory Agreement

At a meeting held on December 11, 2006,  the Board of Trustees  (the "Board") of
BBH Trust (the  "Trust")  unanimously  approved  the  renewal of the  Investment
Advisory  Agreement  (the "IA  Agreement")  between the Trust and Brown Brothers
Harriman & Co.  ("BBH") for an  additional  one-year  term.  The  following is a
summary  of the  factors  the  Board  took  into  consideration  in  making  its
determination to approve the renewal of the IA Agreement.

Nature, Extent and Quality of Services Provided by BBH

The Board  noted  that,  under the IA  Agreement  in respect of each Fund,  BBH,
subject  to the  supervision  of the  Board,  is  responsible  for  providing  a
continuous  investment  program and, for each Fund other than the  International
Fund,  makes  purchases and sales of portfolio  securities  consistent  with the
Fund's investment objective and policies.

The Board considered the scope and quality of services provided by BBH under the
IA Agreement  and noted that the scope of services  provided  had expanded  over
time, primarily, as a result of regulatory  developments.  The Board noted that,
for example,  BBH is responsible  for maintaining and monitoring its own and, to
varying degrees,  the Funds' compliance  program,  and these compliance programs
have recently been refined and enhanced in light of new regulatory requirements.
The Board considered the quality of the investment research  capabilities of BBH
and the other  resources it has dedicated to performing  services for the Funds.
The Board concluded that, overall,  they were satisfied with the nature,  extent
and quality of services  provided  (and  expected to be provided) to each of the
Funds under the IA Agreement.

Costs of Services Provided and Profitability to BBH

At  the  request  of  the  Board,  BBH  provided   information   concerning  the
profitability of BBH's investment company,  advisory fees and other fees and its
statement  of  condition  for the recent  period and as of  December  31,  2005,
respectively.  The Board also reviewed BBH's  profitability  data for each Fund,
which  also  included  the  effect  of  revenue  generated  by  the  shareholder
servicing,  administration,  custody  and other  fees paid by a Fund.  The Board
noted that most beneficial  owners of the Funds' shares are holding these shares
in the context of an overall investment  management program for which BBH is the
adviser  and for which BBH  charges  an  investment  management  fee.  Since BBH
excludes  the assets in the Funds when  calculating  its  advisory  fees for its
clients,  the  Board  agreed  that  it is  appropriate  in an  analysis  of Fund
profitability  to reduce the advisory  fees for the Funds by the  advisory  fees
that otherwise would have been earned by BBH on the assets involved.

The Board discussed the difficulty of making  comparisons of profitability  from
fund  advisory  contracts  because  comparative  information  is  not  generally
publicly available and is affected by numerous factors,  including the structure
of the  particular  adviser,  the types of funds it manages,  its business  mix,
numerous assumptions  regarding  allocations and the adviser's capital structure
and  cost of  capital.  In  considering  profitability  information,  the  Board
considered  the effect of fall-out  benefits on BBH's  expenses,  as well as the
"revenue  sharing"  arrangements BBH has entered into with certain entities that
distribute  shares of the Funds.  The Board  focused on  profitability  of BBH's
relationships with the Funds before taxes and distribution expenses. The

- --------------------------------------------------------------------------------



BBH TAX FREE SHORT/INTERMEDIATE FIXED INCOME FUND
- --------------------------------------------------------------------------------
DISCLOSURE OF ADVISOR SELECTION (CONTINUED)
DECEMBER 31, 2006 (UNAUDITED)

Board concluded that it was satisfied that BBH's level of profitability from its
relationship with each Fund was not excessive.

The Board also  considered  the advisory  fees of each Fund in comparison to the
fees of comparable  funds.  The Board recognized that the expense ratios for the
Funds potentially  reflected on BBH's provision of services,  as BBH is directly
the provider of substantial  services and coordinates  services  provided to the
Fund by  others.  The Board  took note of  situations  in which BBH  waived  its
management fee or reimbursed a Fund's expenses.

Fall-Out Benefits

The Board considered that BBH did not allocate the Funds' portfolio transactions
for third party  research,  although it did benefit  from  proprietary  research
received from brokers that execute the Funds' purchases and sales of securities.
The Board recognized that the aggregate amount of commissions  generated by Fund
transactions  was  unlikely to result in the Funds  receiving  from full service
broker dealers substantial discounts on commission rates. The Board received and
reviewed  information  concerning  BBH's  policies  with  respect to  allocating
portfolio brokerage.

The Board also  considered  that BBH receives  shareholder  servicing  fees from
certain funds, and is the Funds' administrator, custodian and securities lending
agent.  The Board  noted that BBH  retained no portion of the 12b-1 fees paid by
the Fund that operated with a plan.

The Board recognized that BBH's  profitability would be somewhat lower if it did
not receive  proprietary  research for commissions or, if it did not receive the
other benefits described above. The Board recognized that most Fund shareholders
were also BBH clients,  and that substantial assets are invested in the Funds as
a result of an overall investment  management  program for the shareholder.  The
Board  noted that the Funds also derive  reputational  and other  benefits  from
their  association  with BBH and their use of the BBH name, which is licensed to
the Funds by BBH. Thus,  the Board did not believe that BBH revenues  associated
with its clients should be fairly regarded as "fallout" benefit from the Funds.

Economies of Scale

The  Board  noted  that  the  Funds'  advisory  fee  schedules  do  not  contain
breakpoints. As a result, if assets increase, the fee rates would not be reduced
on the  incremental  assets.  There may be other economies of scale because many
expenses did not rise (and fall)  proportionally to increases (and decreases) in
total net assets.  The Board noted that BBH had priced the advisory  services in
recognition  of  the  fact  that  it  was  largely  its  own  clients  who  were
shareholders  and,  accordingly,  sought  to  assure  that the cost of  advisory
service and total expenses for each Fund were fair and reasonable. Consequently,
the advisory fees are in the range of institutional separate account fees, which
is to say substantially  below, even taking into account the BBH  administration
fees,  typical  mutual  fund fees.  In  addition,  the Board  noted that BBH had
supported and continued to support certain Funds through fee waivers and expense
reimbursements. Based on information they had been provided over many years, the
Board  observed  that in the mutual fund  industry as a whole,  as well as among
funds similar to the Funds, there appeared to be no uniformity or pattern in the
fees and  asset  levels at which  breakpoints  (if any)  apply.  In light of the
Fund's  current  size and expense  structure,  the Board  concluded  that it was
unnecessary at this time to consider breakpoints.

Investment Results

The Board considered the investment  results of each of the Funds as compared to
investment  companies  with its peers and with one or more  selected  securities
indices.  In addition to the information  received by the Board for the meeting,
the  Board  received  detailed  performance  information  for each  Fund at each
regular  Board  meeting  during the year.  At the  meeting,  the Board  reviewed
information  showing  performance  of each Fund compared to the peers  generally
over the 1-, 3-, 5- and since  inception  periods  ended  October  31,  2005 and
compared to one or more securities indices over comparable periods.

Advisory Fee Rate

The Board  considered  the advisory fee rate paid by each Fund to BBH. The Board
recognized that it is difficult to make  comparisons of these fees, and combined
advisory and  administration  fees, because there are variations in the services
that are included in the fees paid by other funds.

BBH also manages accounts for institutional  clients with investment  objectives
similar  to  those  of  certain  Funds.  The  fee  rates  payable  by the  BBH's
institutional clients are generally comparable although occasionally lower, than
the rates  paid by the  Funds.  BBH  reviewed  with the  Board  the  significant
differences in the scope of services that BBH provides to institutional  clients
and to the Funds through both the IA and Administration  Agreements (the "Admin.
Agreements"). For example, BBH provides, among other things, officers (including
the  Funds'  Chief   Compliance   Officer  and  officers  to  provide   required
certifications) and administrative services, such as shareholder communications,
and tax compliance, with the attendant costs and exposure to liability. BBH also
coordinates  the  provision  of services to the Funds by  nonaffiliated  service
providers.  These services  normally are not provided to non investment  company
clients,  and fees  charged  to the  Funds  reflect  the  costs and risks of the
additional obligations. The Board also noted that since the Funds are constantly
issuing and redeeming  their shares,  they are more  difficult to manage than an
institutional account, where the assets are relatively stable. Accordingly,  the
Board did not place significant weight on these fee comparisons.

       The following factors specific to BBH Tax Free  Short/Intermediate  Fixed
Income Fund also were noted and  considered  by the Board in deciding to approve
the continuation of the IA Agreements:

       The  Trustees  reviewed  information  showing  performance  of  the  Fund
compared to the Lehman 3-Year  Municipal Bond Index.  The Fund generally  lagged
the Index over all relevant periods,  which resulted from management's  decision
to construct a defensive  portfolio  in recent  years.  The Trustees  understood
management's  decision and were pleased to see a portfolio  with higher  quality
securities and a shorter duration than the Index. The Trustees viewed with favor
this  performance  and noted the benchmark has no fees.  The Trustees also noted
the  Fund's  expense  ratio was in line with or lower than many Funds of similar
size and investment mandate. Taking into account these comparisons and the other
factors  considered,  the Trustees  concluded that the Fund's investment results
over time and its total expense ratio had been satisfactory.

BBH TAX EXEMPT MONEY FUND

NOTES TO FINANCIAL STATEMENTS
December 31, 2006 (unaudited)

1. Organization and Significant  Accounting Policies.  BBH Tax Exempt Money Fund
   (the "Fund") is a separate,  diversified  series of BBH Trust (the  "Trust"),
   which is registered under the Investment Company Act of 1940, as amended. The
   Trust  is  an  open-end   management   investment   company  organized  as  a
   Massachusetts  business trust on June 7, 1983. The Fund commenced  operations
   on February 22, 1999. The Declaration of Trust permits the Trustees to create
   an unlimited  number of series,  each of which may issue a separate  class of
   shares.  The Trustees have authorized the issuance of an unlimited  number of
   shares of the Fund with a par value of $0.01 per share. At December 31, 2006,
   there were four series of the Trust.

   The Fund's  financial  statements are prepared in accordance  with accounting
   principles generally accepted in the United States of America,  which require
   management  to make  certain  estimates  and  assumptions  at the date of the
   financial  statements  and are based,  in part, on the  following  accounting
   policies. Actual results could differ from those estimates.

   A. Valuation of  Investments.  The Fund values its  investments  at amortized
      cost, which approximates  market value. The amortized cost method values a
      security  at its cost at the time of  purchase  and  thereafter  assumes a
      constant  amortization to maturity of any discount or premium.  The Fund's
      use of amortized  cost is in compliance  with Rule 2a-7 of the  Investment
      Company Act of 1940.

   B. Investment Transactions and Income.  Investment transactions are accounted
      for on the trade date.  Realized gains and losses, if any, from investment
      transactions  are  determined  on the basis of identified  cost.  The Fund
      invests primarily in debt securities issued by municipalities. The ability
      of the  issuers of the debt  securities  to meet their  obligation  may be
      affected by economic  developments  in a specific  state or  municipality.
      Interest  income   consists  of  interest   accrued  and  discount  earned
      (including   both  original   issue  and  market   discount)  and  premium
      amortization on the  investments of the Fund,  accrued ratably to the date
      of maturity.

   C. Federal  Income  Taxes.  Each series of the Trust is treated as a separate
      entity for federal income tax purposes.  It is the Fund's policy to comply
      with the provisions of the Internal  Revenue Code  applicable to regulated
      investment  companies and to distribute  substantially  all of its taxable
      income to its shareholders.  Accordingly,  no federal income tax provision
      is required.  At December 31, 2006,  the cost of  investments  for federal
      income tax purposes was equal to the  amortized  cost of  investments  for
      financial statement purposes.

   D. Dividends and Distributions to Shareholders. Dividends from net investment
      income are declared daily and paid monthly to shareholders.

   E. Accounting  Developments.  In June 2006,  Financial  Accounting  Standards
      Board  Interpretation No. 48, Accounting for Uncertainty in Income Taxes -
      an  interpretation  of FASB  Statement  109  (FIN  48) was  issued  and is
      effective for fiscal years  beginning after December 15, 2006. FIN 48 sets
      forth

      a  threshold  for  financial   statement   recognition,   measurement  and
      disclosure  of a tax  position  taken  or  expected  to be  taken on a tax
      return.  While  not  expected  to have a  material  impact  on the  Fund's
      financial  statements,  management will be evaluating the impact,  if any,
      the  adoption  of FIN 48 will have on the Funds' net assets and results of
      operations.

      In September 2006,  Statement of Financial  Accounting  Standards No. 157,
      Fair Value Measurements (SFAS 157), was issued and is effective for fiscal
      years  beginning  after  November 15,  2007.  SFAS 157 defines fair value,
      establishes a framework for measuring  fair value and expands  disclosures
      about fair value  measurements.  Management  is currently  evaluating  the
      implication  of SFAS 157. At this time its impact on the Fund's  financial
      statements has not yet been determined.

2. Transactions with Affiliates.

      Investment  Advisory Fees. The Trust has an investment  advisory agreement
      with Brown Brothers Harriman ("BBH") for which BBH receives a fee from the
      Fund  calculated  daily and paid monthly at an annual rate of 0.15% of the
      Fund's  average  daily  net  assets.  BBH  has  established  a  separately
      identifiable  department  ("SID") to provide  investment  advice to mutual
      funds.  The SID is registered with the Securities and Exchange  Commission
      under  the  Investment  Advisors  Act of 1940.  For the six  months  ended
      December 31, 2006, the Fund incurred $358,126 for advisory services.

      Administrative Fees. The Trust has an administration  agreement with Brown
      Brothers Harriman Trust Company,  LLC ("BBHTC") for which BBHTC receives a
      fee from the Fund  calculated  daily and paid monthly at an annual rate of
      0.10%  of  the   Fund's   average   daily   net   assets.   BBHTC   has  a
      sub-administration  services  agreement  with Federated  Services  Company
      ("FSC") for which FSC  receives  compensation  paid by BBHTC.  For the six
      months  ended   December  31,  2006,   the  Fund  incurred   $238,750  for
      administrative services.

      Shareholder   Servicing  Fees.  The  Trust  has  a  shareholder  servicing
      agreement  with BBH for which BBH receives a fee from the Fund  calculated
      daily and paid  monthly at an annual  rate of 0.25% of the Fund's  average
      daily net assets.  For the six months ended  December  31, 2006,  the Fund
      incurred $596,876 for shareholder servicing services.

      Custody  and  Accounting  Fees.  BBH acts as a  custodian  and  receives a
      custody  and  accounting  fee  from  the Fund  calculated  daily  and paid
      monthly. The custody fee is a transaction based fee with an annual minimum
      of $20,000, and the accounting fee is calculated at 0.01% per annum on the
      first $1 billion of net assets and 0.005% per annum on all net assets over
      $1 billion.  For the six months ended December 31, 2006, the Fund incurred
      $91,312 for custody and  accounting  services.  These fees were reduced by
      $15,874  as a result of an  expense  offset  arrangement  with the  Fund's
      custodian.  In the event  that the Fund is  overdrawn,  under the  custody
      agreement with BBH, BBH will make

DISCLOSURE OF FUND EXPENSES
December 31, 2006 (unaudited)


EXAMPLE

As a shareholder  of BBH Tax Exempt Money Fund (the  "Fund"),  you may incur two
types  of  costs:  (1)  transaction  costs  on  purchase  payments,   reinvested
dividends,  or other  distributions;  and exchange  fees; and (2) ongoing costs,
including management fees; and other Fund expenses.  This Example is intended to
help you understand your ongoing costs (in dollars) of investing in the Fund and
to compare  these  costs with the ongoing  costs of  investing  in other  mutual
funds.

The Example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period (July 1, 2006 to December 31, 2006).

ACTUAL EXPENSES

The first line of the table below  provides  information  about  actual  account
values and actual expenses.  You may use information in this line, together with
the amount you invested, to estimate the expenses that you paid over the period.
Simply divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6),  then  multiply  the result by the number in the first
line under the heading  entitled  "Expenses  Paid During the Period" to estimate
the expenses you paid on your account during the period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second  line of the table  below  provides  information  about  hypothetical
account  values and  hypothetical  expenses  based on the Fund's actual  expense
ratio and an assumed rate of return of 5% per year before expenses, which is not
the Fund's actual return.  The hypothetical  account values and expenses may not
be used to estimate  the actual  ending  account  balance or  expenses  you paid
during the period.  You may use this information to compare the ongoing costs of
investing in the Fund and other funds.  To do so,  compare this 5%  hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of other funds.

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

                                                               Expenses Paid

(1)   Expenses  are  equal to the  Fund's  annualized  expense  ratio of  0.58%,
      multiplied  by the average  account  value over the period,  multiplied by

(2)   Assumes  a  return  of  5%  before  expenses.   For  the  purpose  of  the
      calculation,  the applicable  annualized  expense ratio is subtracted from
      the assumed return before expenses.

DISCLOSURE OF ADVISOR SELECTION

Approval of Continuation of Investment Advisory Agreement

At a meeting held on December 11, 2006,  the Board of Trustees  (the "Board") of
BBH Trust (the  "Trust")  unanimously  approved  the  renewal of the  Investment
Advisory  Agreement  (the "IA  Agreement")  between the Trust and Brown Brothers
Harriman ("BBH") for an additional  one-year term. The following is a summary of
the factors the Board took into  consideration  in making its  determination  to
approve the renewal of the IA Agreement.


Nature, Extent and Quality of Services Provided by BBH

The Board  noted  that,  under the IA  Agreement  in respect of each Fund,  BBH,
subject  to the  supervision  of the  Board,  is  responsible  for  providing  a
continuous  investment  program and, for each Fund other than the  International
Fund,  makes  purchases and sales of portfolio  securities  consistent  with the
Fund's investment objective and policies

The Board considered the scope and quality of services provided by BBH under the
IA Agreement  and noted that the scope of services  provided  had expanded  over
time, primarily, as a result of regulatory  developments.  The Board noted that,
for example,  BBH is responsible  for maintaining and monitoring its own and, to
varying degrees,  the Funds' compliance  program,  and these compliance programs
have recently been refined and enhanced in light of new regulatory requirements.
The Board considered the quality of the investment research  capabilities of BBH
and the other  resources it has dedicated to performing  services for the Funds.
The Board concluded that, overall,  they were satisfied with the nature,  extent
and quality of services  provided  (and  expected to be provided) to each of the
Funds under the IA Agreement.

Costs of Services Provided and Profitability to BBH

At  the  request  of  the  Board,  BBH  provided   information   concerning  the
profitability of BBH's investment company,  advisory fees and other fees and its
statement  of  condition  for the recent  period and as of  December  31,  2005,
respectively.  The Board also reviewed BBH's  profitability  data for each Fund,
which  also  included  the  effect  of  revenue  generated  by  the  shareholder
servicing,  administration,  custody  and other  fees paid by a Fund.  The Board
noted that most beneficial  owners of the Funds' shares are holding these shares
in the context of an overall investment  management program for which BBH is the
adviser  and for which BBH  charges  an  investment  management  fee.  Since BBH
excludes  the assets in the Funds when  calculating  its  advisory  fees for its
clients,  the  Board  agreed  that  it is  appropriate  in an  analysis  of Fund
profitability  to reduce the advisory  fees for the Funds by the  advisory  fees
that otherwise would have been earned by BBH on the assets involved.

The Board discussed the difficulty of making  comparisons of profitability  from
fund  advisory  contracts  because  comparative  information  is  not  generally
publicly available and is affected by numerous factors,  including the structure
of the  particular  adviser,  the types of funds it manages,  its business  mix,
numerous assumptions  regarding  allocations and the adviser's capital structure
and cost of capital. In consider-


FINANCIAL STATEMENT DECEMBER 31, 2006                                         19



BBH TAX EXEMPT MONEY FUND
- --------------------------------------------------------------------------------
DISCLOSURE OF ADVISOR SELECTION (continued)
December 31, 2006 (unaudited)


ing  profitability  information,  the Board  considered  the effect of  fall-out
benefits on BBH's expenses,  as well as the "revenue  sharing"  arrangements BBH
has entered into with certain entities that distribute  shares of the Funds. The
Board  focused on  profitability  of BBH's  relationships  with the Funds before
taxes and distribution  expenses. The Board concluded that it was satisfied that
BBH's  level of  profitability  from its  relationship  with  each  Fund was not
excessive.

The Board also  considered  the advisory  fees of each Fund in comparison to the
fees of comparable  funds.  The Board recognized that the expense ratios for the
Funds potentially  reflected on BBH's provision of services,  as BBH is directly
the provider of substantial  services and coordinates  services  provided to the
Fund by  others.  The Board  took note of  situations  in which BBH  waived  its
management fee or reimbursed a Fund's expenses.

Fall-Out Benefits

The Board considered that BBH did not allocate the Funds' portfolio transactions
for third party  research,  although it did benefit  from  proprietary  research
received from brokers that execute the Funds' purchases and sales of securities.
The Board recognized that the aggregate amount of commissions  generated by Fund
transactions  was  unlikely to result in the Funds  receiving  from full service
broker dealers substantial discounts on commission rates. The Board received and
reviewed  information  concerning  BBH's  policies  with  respect to  allocating
portfolio brokerage.

The Board also  considered  that BBH receives  shareholder  servicing  fees from
certain funds, and is the Funds' administrator, custodian and securities lending
agent.  The Board  noted that BBH  retained no portion of the 12b-1 fees paid by
the Fund that operated with a plan.

The Board recognized that BBH's  profitability would be somewhat lower if it did
not receive  proprietary  research for commissions or, if it did not receive the
other benefits described above. The Board recognized that most Fund shareholders
were also BBH clients,  and that substantial assets are invested in the Funds as
a result of an overall investment  management  program for the shareholder.  The
Board  noted that the Funds also derive  reputational  and other  benefits  from
their  association  with BBH and their use of the BBH name, which is licensed to
the Funds by BBH. Thus,  the Board did not believe that BBH revenues  associated
with its clients should be fairly regarded as "fallout" benefit from the Funds.


Economies of Scale

The  Board  noted  that  the  Funds'  advisory  fee  schedules  do  not  contain
breakpoints. As a result, if assets increase, the fee rates would not be reduced
on the  incremental  assets.  There may be other economies of scale because many
expenses did not rise (and fall)  proportionally to increases (and decreases) in
total net assets.  The Board noted that BBH had priced the advisory  services in
recognition  of  the  fact  that  it  was  largely  its  own  clients  who  were
shareholders  and,  accordingly,  sought  to  assure  that the cost of  advisory
service and total expenses for each Fund were fair and reasonable. Consequently,
the advisory

- --------------------------------------------------------------------------------
DISCLOSURE OF ADVISOR SELECTION (continued)
December 31, 2006 (unaudited)


fees are in the range of  institutional  separate  account fees, which is to say
substantially  below,  even taking into  account  the BBH  administration  fees,
typical  mutual fund fees.  In addition,  the Board noted that BBH had supported
and  continued  to  support  certain  Funds  through  fee  waivers  and  expense
reimbursements. Based on information they had been provided over many years, the
Board  observed  that in the mutual fund  industry as a whole,  as well as among
funds similar to the Funds, there appeared to be no uniformity or pattern in the
fees and  asset  levels at which  breakpoints  (if any)  apply.  In light of the
Fund's  current  size and expense  structure,  the Board  concluded  that it was
unnecessary at this time to consider breakpoints.


Investment Results

The Board considered the investment  results of each of the Funds as compared to
investment  companies  with its peers and with one or more  selected  securities
indices.  In addition to the information  received by the Board for the meeting,
the  Board  received  detailed  performance  information  for each  Fund at each
regular  Board  meeting  during the year.  At the  meeting,  the Board  reviewed
information  showing  performance  of each Fund compared to the peers  generally
over the 1-, 3-, 5- and since  inception  periods  ended  October  31,  2005 and
compared to one or more securities indices over comparable periods.


Advisory Fee Rate

The Board  considered  the advisory fee rate paid by each Fund to BBH. The Board
recognized that it is difficult to make  comparisons of these fees, and combined
advisory and  administration  fees, because there are variations in the services
that are included in the fees paid by other funds.

BBH also manages accounts for institutional  clients with investment  objectives
similar  to  those  of  certain  Funds.  The  fee  rates  payable  by the  BBH's
institutional clients are generally comparable although occasionally lower, than
the rates  paid by the  Funds.  BBH  reviewed  with the  Board  the  significant
differences in the scope of services that BBH provides to institutional  clients
and to the Funds through both the IA and Administration  Agreements (the "Admin.
Agreements"). For example, BBH provides, among other things, officers (including
the  Funds'  Chief   Compliance   Officer  and  officers  to  provide   required
certifications) and administrative services, such as shareholder communications,
and tax compliance, with the attendant costs and exposure to liability. BBH also
coordinates  the  provision  of services to the Funds by  nonaffiliated  service
providers.  These services  normally are not provided to non investment  company
clients,  and fees  charged  to the  Funds  reflect  the  costs and risks of the
additional obligations. The Board also noted that since the Funds are constantly
issuing and redeeming  their shares,  they are more  difficult to manage than an
institutional account, where the assets are relatively stable. Accordingly,  the
Board did not place significant weight on these fee comparisons.

The following  factors specific to BBH Tax Exempt Money Fund also were noted and
considered  by the Board in  deciding  to  approve  the  continuation  of the IA
Agreements:

The Trustees reviewed  information  showing  performance of the Fund compared to
iMoneyNet (Tax Free Retail). The Fund outperformed the Average over all relevant
periods.  The  Trustees  also  viewed  with favor that the Fund's  portfolio  of
investments had an overall high quality while the Fund's total expense ratio was
lower that the  iMoneyNet  Average.  The  Trustees  also noted that the Fund had
successfully  maintained  a stable  net asset  value of one dollar at all times.
Taking into account  these  comparisons  and the other factors  considered,  the
Trustees  concluded that the Fund's  investment  results over time and its total
expense ratio had been satisfactory.

4. The Registrant's other certifying officer and I are responsible for
   establishing and maintaining disclosure controls and

        a.) designed such disclosure controls and procedures, or caused such
            disclosure controls and procedures to be designed under
            our supervision, to ensure that material information relating
            to the Registrant, including its consolidated subsidiaries, is made
            known to us by others within those entities, particularly during
            the period in which this report is being prepared;

       b.) designed such disclosure controls and procedures, or
           caused such disclosure controls and  procedures to be designed
         under our supervision, 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;

c.) evaluated the effectiveness of the Registrant's disclosure
    controls and procedures and presented in this report our

    controls and procedures, as of a date within 90 days prior
            to the filing date of this report based on such evaluation; and

        d.) disclosed in this report any change in the Registrant's internal
            control over financial reporting that occurred during the
            Registrant's most recent fiscal half-year (the Registrant's second
            fiscal half year in the case of an annual report) that has
            materially affected, or is reasonably likely to materially affect,
            the Registrant's internal control over financial reporting; and

5. The Registrant's other certifying officer and I have disclosed
   to the Registrant's auditors and the audit committee of the Registrant's
   board of directors (or persons performing the equivalent functions):

a.) all significant deficiencies and material weaknesses in the design
or operation of internal control over financial reporting
             which are reasonably likely to adversely affect the Registrant's
             ability to record, process, summarize, and report financial
             information; and

         b.) any fraud, whether or not material, that involves management or
             other employees who have a significant role in the Registrant's
             internal control over financial reporting.


6.     The Registrant's other certifying officer and I have indicated in this
       report whether or not there were significant changes in internal
       controls or in other factors that could significantly affect
       internal controls subsequent to the date of our most recent evaluation,
       including any corrective actions with regard to significant deficiencies
       and material weaknesses.
