             Report of Independent Registered Public Accounting Firm


To the Board of Directors and Members of
The Topiary Fund for Benefit Plan Investors (BPI) LLC

In our opinion, the accompanying  consolidated statement of assets,  liabilities
and members' capital, and the related consolidated statements of operations,  of
changes  in  members'  capital  and of cash flows and the  financial  highlights
present fairly, in all material respects,  the financial position of The Topiary
Fund for Benefit Plan  Investors  (BPI) LLC and its  subsidiary  (the "Fund") at
September 30, 2007, the results of their operations and their cash flows for the
period from April 1, 2007 through  September 30, 2007,  and the changes in their
members' capital and the financial highlights for each of the periods presented,
in conformity with accounting principles generally accepted in the United States
of America.  These consolidated  financial  statements and financial  highlights
(hereafter referred to as "financial  statements") are the responsibility of the
Fund's  management;  our  responsibility  is to  express  an  opinion  on  these
financial  statements  based on our  audits.  We  conducted  our audits of these
financial  statements  in accordance  with the  standards of the Public  Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements,  assessing the accounting  principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

As more fully described in Note 10 to the financial  statements,  the Members of
the Fund have approved a reorganization  plan whereby  substantially  all of the
assets and  liabilities of the Fund will be acquired by another fund in exchange
for interests in the latter. The reorganization plan became effective on October
1, 2007.

THE TOPIARY FUND FOR BENEFIT PLAN INVESTORS (BPI) LLC
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
FOR THE SIX MONTHS ENDED SEPTEMBER 30, 2007
--------------------------------------------------------------------------------

1.  ORGANIZATION

The Topiary Fund for Benefit Plan Investors (BPI) LLC (the "Fund") is a Delaware
limited liability company organized on December 8, 2003 and commenced operations
October 1, 2004.  The Fund is  registered  under the  Investment  Company Act of
1940, as amended (the "1940 Act"), as a closed-end, non-diversified,  management
investment company.  The Fund's interests (the "Interests") are registered under
the  Securities  Act of 1933,  as amended (the "1933  Act"),  but are subject to
substantial  limits  on  transferability   and  resale.  The  Fund's  investment
objective  is to  generate  long-term  capital  appreciation.  The Fund seeks to
achieve this objective by investing  substantially  all of its investable assets
into The  Topiary  Offshore  Fund for  Benefit  Plan  Investors  (BPI)  LDC (the
"Offshore  Fund"),  a Cayman  Islands  limited  duration  company  with the same
investment   objectives  as  the  Fund.   The  Offshore  Fund  in  turn  invests
substantially  all of its  investable  assets  in The  Topiary  Master  Fund for
Benefit Plan Investors  (BPI) LLC (the "Master Fund"),  a registered  investment
company with the same  investment  objectives as the Fund and the Offshore Fund.
The Fund owns 100% of the  beneficial  interests of the Offshore  Fund,  and the
Offshore Fund owns approximately 98.6% of the beneficial interests in the Master
Fund at September 30, 2007. The remaining balance of the Master Fund is owned by
DBAH  Capital,  L.L.C,  an  affiliate  of DB  Investment  Managers,  Inc.  These
financials  statements are the  consolidation of the Fund and the Offshore Fund.
Inter-company balances have been eliminated through consolidation.  The Offshore
Fund commenced operations on October 1, 2004.

The Fund's Board of Directors (the "Board") has overall responsibility to manage
and control the  business  operations  of the Fund on behalf of the members (the
"Members").  All of the Board are and will be  persons  who are not  "interested
persons" (as defined in the 1940 Act) with respect to the Fund.

DB Investment  Managers,  Inc.,  performing services as Topiary Fund Management,
(the  "Adviser")  serves as the  investment  adviser of the Fund  subject to the
ultimate  supervision  of and subject to any policies  established by the Board,
pursuant to the terms of an investment  management  agreement with the Fund (the
"Investment  Management  Agreement").  Pursuant  to  the  Investment  Management
Agreement,  the Adviser  provides  the Fund with  ongoing  investment  guidance,
policy direction,  and monitoring of the Fund. The Adviser is an indirect wholly
owned  subsidiary  of  Deutsche  Bank AG  ("Deutsche  Bank"),  an  international
commercial  and  investment  banking  group,  and is registered as an investment
adviser under the  Investment  Advisers Act of 1940,  as amended (the  "Advisers
Act").

Generally,  initial  and  additional  applications  for  Interests  by  eligible
investors  may be accepted at such times as the Fund's  operating  agreement may
determine.  The Fund reserves the right to reject any applications for interests
in the Fund. The Fund from time

to time may offer to repurchase  Interests.  These  repurchases  will be made at

sole discretion.

The  performance  of the Fund is  directly  affected by the  performance  of the

an integral part of these financial statements.

2.  SIGNIFICANT ACCOUNTING POLICIES

A.  VALUATIONS

The Fund's  investment in the Master Fund  represents  substantially  all of the
Fund's assets.  All investments  owned are carried at value which is the portion
of the net asset value of the Master Fund held by the Fund.  The  accounting for
and valuation of investments by the Master Fund is discussed in the notes to the
financial  statements for the Master Fund, which are included  elsewhere in this
report.

B.  INCOME RECOGNITION AND SECURITY TRANSACTIONS

Investments  in the  Master  Fund  are  recorded  on the  effective  date of the
subscription in the Master Fund. The Fund records its proportionate share of the
Master Fund's income, expenses, and realized and unrealized gains and losses. In
addition,  interest  income on the Fund's cash balance is recorded on an accrual
basis and the Fund accrues its own expenses as incurred.

C.  FUND COSTS

The Fund bears all expenses  incurred in its business  other than those that the
Adviser assumes.  The expenses of the Fund include,  but are not limited to, the
following:  all  costs and  expenses  related  to  investment  transactions  and
positions for the Fund's  account;  legal fees;  accounting  and auditing  fees;
custodial  fees;  costs of  computing  the  Fund's  net  asset  value;  costs of

2.  SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

D.  INCOME TAXES

The Fund intends to operate and has elected to be treated as a  partnership  for
Federal  income tax  purposes.  Accordingly,  no  provision  for the  payment of
Federal,  state  or local  income  taxes  has  been  provided.  Each  Member  is
individually  required to report on its own tax return its distributive share of
the Fund's  taxable  income or loss. The Master Fund withholds and pays taxes on
U.S. source income and U.S. effectively connected income, if any, allocated from
underlying   investments  to  the  extent  such  income  is  not  exempted  from
withholding  under the Internal Revenue Code and Regulations  there under.  Such
amounts are treated by the Members as withholding tax credits for Federal income
tax  purposes.  The actual amount of such taxes is not known until all K-1s from
underlying  funds are received,  usually in the following tax year. Prior to the
final  determination,  the amount of the tax is estimated  based on  information
available.  The final  tax could be  different  from the  estimated  tax and the
difference could be significant.

E.  CASH AND CASH EQUIVALENTS

Cash and cash  equivalents,  if any,  consist  of monies on deposit at PNC Bank,
N.A. The Fund treats all financial  instruments  that mature within three months
as cash equivalents.

F.  USE OF ESTIMATES

The preparation of financial statements in conformity with accounting principles
generally  accepted in the United States of America requires the Adviser to make
estimates  and  assumptions  that  affect the  amounts  and  disclosures  in the
financial  statements  and  accompanying  notes.  The Adviser  believes that the
estimates  utilized in preparing the Fund's financial  statements are reasonable
and prudent; however, actual results could differ from these estimates.

G.  ALLOCATION OF NET PROFITS AND LOSSES

Net investment income (loss) and net realized and unrealized gains and losses on
investments for the Fund are allocated to the Members' Capital Accounts based on
their  respective  capital  balances at the beginning of each allocation  period
relative to the capital of all Members'  Capital  Accounts.  The beginning of an
allocation  period is defined as the beginning of each fiscal year,  the date of
admission  of any new  member,  or the date of any  additional  subscription  or
redemption by a member.

H.  EXPENSE LIMITATION

Pursuant  to the Expense  Limitation  Agreement,  the Adviser has  contractually
agreed to waive and/or  reimburse the Fund's expenses to the extent necessary to
ensure that the Fund's annualized expenses (excluding the Incentive  Allocation,
if any) will not exceed 1.75% including the Fund's allocated  portion of expense
incurred by the Master Fund. The initial

term of the Expense Limitation  Agreement is the first fiscal year of the Fund's
operations,  and will be  automatically  renewed for each fiscal year thereafter
unless the Adviser  provides  written  notice to the Fund and the Master Fund of
the  termination of the Expense  Limitation  Agreement at least 30 days prior to
the end of the then-current term.

3.  RELATED PARTY TRANSACTIONS

A.  MANAGEMENT FEE

The Adviser provides certain management and administration services to the Fund,
including,  among  other  things,  providing  office  space  and  other  support
services.  In consideration for such management  services,  the Master Fund pays
the Adviser a management fee (the  "Management  Fee") at an annual rate of 1.00%
of the Master Fund's month end net assets,  including assets attributable to the
Adviser (or its  affiliates)  and before giving effect to any repurchases by the
Master Fund of interests in the Master Fund. The Management Fee accrues  monthly
and is payable at the end of each  quarter.  As an investor in the Master  Fund,
the  Fund's  value  of its  investment  in the  Master  Fund is  reduced  by the
Management Fee accrued by the Master Fund.

B.  BOARD FEES

Board fees are paid at the Master Fund level. See accompanying note in the
Master Fund notes attached.

C.  INCENTIVE ALLOCATION

As of each March 31, upon any  repurchases of Interests  (solely with respect to
the  Interest   repurchased),   and  upon  termination  of  the  Fund  (each,  a
"Performance Period"), a reallocation (the "Incentive  Allocation") will be made
from the Capital  Account of each  Member to the Capital  Account of the Special
Advisory  Member (the Adviser) equal to 10% of the amount,  if any, by which the
net profit  allocated  to such  Member's  Capital  Account for such  Performance
Period in excess of the Hurdle  Rate  (based on the 90-day  U.S.  Treasury  bill
rates) for such Performance Period exceeds the positive balance of such Member's
Loss Carryforward  Account.  The Incentive Allocation will be applied on a "high
water mark" basis such that in the event a Capital Account suffers a net loss in
a  particular  Performance  Period,  no Incentive  Allocation  will be made with
respect to such Performance Period or any subsequent  Performance Period,  until
such net loss is first recovered  (taking into account interim  repurchases,  if
any).  For the six months  ended  September  30,  2007,  the  Adviser  earned an
Incentive Allocation of $120,437.

The Hurdle Rate is  calculated  monthly  using the average of the weekly  91-day
U.S.  Treasury bill for that month. For the six months ended September 30, 2007,
the average Hurdle Rate was 4.549%.

"Administration  Agreement")  and with the approval of the Fund's  Board,  PFPC,
Inc.  (an  affiliate  of  PNC  Bank,   N.A.)  ("PFPC")   serves  as  the  Fund's

6.  FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK

In the normal course of business,  the Investment Funds (the "Investment Funds")
in which the Master Fund invests trade various  financial  instruments and enter
into various  investment  activities  with  off-balance  sheet risk.  The Master
Fund's off-balance sheet risk in these financial instruments is discussed in the
notes to the Master Fund's financial statements.

7.  CONCENTRATION OF RISK

The Master Fund invests  primarily in Investment  Funds that are not  registered
under  the 1940 Act and  invest  in and  actively  trade  securities  and  other
financial  instruments  using  different  strategies and investment  techniques,
including leverage that may involve significant risks.

The Master Fund's  concentration of risk is discussed in the notes to the Master
Fund's financial statements.

8.  GUARANTOR OBLIGATIONS AND INDEMNIFICATIONS

In the normal course of business,  the Fund enters into contracts that contain a
variety of warranties and representations that provide general indemnifications.
The Fund's maximum exposure under these  arrangements is unknown,  as this would
involve  future  claims  that may be made  against  the Fund  that  have not yet
occurred. However, the Fund expects the risk of loss to be remote.

9.  NEW ACCOUNTING PRONOUNCEMENTS

In July 2006,  the  Financial  Accounting  Standards  Board (the "FASB")  issued
Interpretation  No.  48,  "Accounting  for  Uncertainty  in  Income  Taxes  - an
interpretation of FASB Statement No. 109" ("FIN 48"). FIN 48 establishes for all
entities,  including pass-through entities such as the Fund, a minimum threshold
for financial statement  recognition of the benefit of positions taken in filing
tax  returns   (including   whether  an  entity  is  taxable  in  a   particular
jurisdiction),  and  requires  certain  expanded  tax  disclosures.  FIN  48  is
effective  for fiscal years  beginning  after  December  15, 2006,  and is to be
applied  to all open tax  years  as of the date of  effectiveness.  Based on the
Manager's analysis,  the determination has been made that the adoption of FIN 48
did not have an impact to the Fund's  financial  statements  upon adoption.  The
Manager  continually reviews the Fund's tax positions and such conclusions under
FIN 48 based on factors,  including, but not limited to, ongoing analyses of tax
laws, regulations and interpretations, thereof.

THE TOPIARY FUND FOR BENEFIT PLAN INVESTORS (BPI) LLC
PORTFOLIO PROXY VOTING POLICIES AND PROCEDURES; SEC FILINGS (UNAUDITED)
--------------------------------------------------------------------------------


The Fund invests substantially all of its assets in the securities of Investment
Funds, which are privately placed investment vehicles,  typically referred to as
"hedge  funds."  These  securities do not typically  convey  traditional  voting
rights to the holder and the occurrence of corporate governance or other notices
for this type of  investment  is  substantially  less than that  encountered  in
connection with registered equity  securities.  However,  to the extent the Fund
receives  notices or proxies from Investment Funds (or receives proxy statements
or similar notices in connection with any other portfolio securities);  the Fund
has  delegated  proxy voting  responsibilities  to the Adviser.  The Adviser has
adopted its own Proxy Voting Policies and Procedures ("Policies").  The Policies
address,  among other  things,  conflicts of interest that may arise between the
interests  of the Fund,  and the  interests  of the Adviser and its  affiliates,
including the Fund's principal underwriter.

A description of the Adviser's  Policies is available (i) without  charge,  upon
request, by calling the Fund toll-free at 1-888-262-0695,  and (ii) on the SEC's
website at WWW.SEC.GOV.

In addition,  the Fund is required to file new Form N-PX with its complete proxy
voting  record for the 12 months  ended June 30th,  no later than August 31st of
each year. The funds Form N-PX is available (i) without charge, upon request, by
calling the Fund toll free at  1-888-262-0695  and (ii) on the SEC's  website at
WWW.SEC.GOV.

The Fund files its complete schedule of portfolio  holdings with the SEC for the
first  quarter and the third quarter of each fiscal year on Form N-Q. The Fund's
Form N-Q filings are available on the SEC's website at WWW.SEC.GOV.  Those forms
may be reviewed and copied at the SEC's Public Reference Room in Washington D.C.
Information  on the  operation of the Public  Reference  Room may be obtained by
calling 1-800-SEC-0330.

             Report of Independent Registered Public Accounting Firm



To the Board of Directors and Members of
The Topiary Master Fund for Benefit Plan Investors (BPI) LLC

In our opinion, the accompanying  statement of assets,  liabilities and members'
capital,  including the schedule of investments,  and the related  statements of
operations,  of changes in members'  capital and of cash flows and the financial
highlights present fairly, in all material  respects,  the financial position of
The Topiary Master Fund for Benefit Plan Investors (BPI) LLC (the "Master Fund")
at September 30, 2007,  the results of its operations and its cash flows for the
period from April 1, 2007 through  September  30,  2007,  and the changes in its
members' capital and the financial highlights for each of the periods presented,
in conformity with accounting principles generally accepted in the United States
of America.  These  financial  statements  and financial  highlights  (hereafter
referred to as  "financial  statements")  are the  responsibility  of the Fund's
management;  our  responsibility  is to express  an  opinion on these  financial
statements  based on our  audits.  We  conducted  our audits of these  financial
statements in accordance  with the  standards of the Public  Company  Accounting
Oversight  Board  (United  States).  Those  standards  require  that we plan and
perform the audit to obtain  reasonable  assurance  about  whether the financial
statements are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements,  assessing the accounting  principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe  that our audits,  which  included  confirmation  of  investments  at
September 30, 2007 by correspondence with the general partners/ managing members
of the investment funds, provide a reasonable basis for our opinion.

As more fully  described in Note 9 to the financial  statements,  the Members of
the Master Fund have approved a reorganization plan whereby substantially all of
the assets and  liabilities  of the Master Fund will be acquired by another fund
in  exchange  for  interests  in the  latter.  The  reorganization  plan  became
effective on October 1, 2007.

THE TOPIARY MASTER FUND FOR BENEFIT PLAN INVESTORS (BPI) LLC
NOTES TO FINANCIAL STATEMENTS
FOR THE SIX MONTHS ENDED SEPTEMBER 30, 2007
--------------------------------------------------------------------------------


1.  ORGANIZATION

The Topiary  Master Fund for Benefit Plan  Investors  (BPI) LLC (the "Fund") was
organized as a Delaware limited  liability company on July 16, 2004. The Fund is
registered  under the  Investment  Company  Act of 1940,  as amended  (the "1940
Act"), as a closed-end,  non-diversified,  management  investment  company.  The
Fund's  interests (the  "Interests")  are registered under the Securities Act of
1933,  as amended (the "1933  Act"),  but are subject to  substantial  limits on
transferability and resale.

The Fund's investment  objective is to generate  long-term capital  appreciation
through a diversified  portfolio with  volatility that is lower than that of the
equity markets and returns that demonstrate little to no correlation with either
equity  or bond  markets.  The Fund acts as a "Master  Fund"  utilizing  capital
generated by investments by The Topiary Offshore Fund for Benefit Plan Investors
(BPI) LDC (the "Offshore Fund") and through direct investments by other Members.
The Offshore  Fund's capital is generated by investments by The Topiary Fund for
Benefit Plan Investors  (BPI) LLC (the "Onshore  Fund").  At September 30, 2007,
the investment by the Offshore Fund constitutes 98.6% of the investment  capital
of the Master Fund,  and the Onshore  Fund  constitutes  100% of the  investment
capital of the Offshore Fund. The balance of the Fund's  capital,  approximately
1.4%,  comprises a direct  investment  by DBAH  Capital  LLC, an affiliate of DB
Investment  Managers,  Inc.  The Fund will  attempt  to achieve  its  investment
objective by investing in the securities of  approximately  50 to 100 Investment
Funds (the "Investment Funds") to be managed pursuant to various alternatives or
non-traditional investment strategies,  which may be viewed as encompassing four
broadly defined primary  categories;  Relative Value;  Event Driven;  Long/Short
Equity; and Global Macro. The Fund commenced operations on October 1, 2004.

The Fund's Board of Directors (the "Board") has overall responsibility to manage
and control the  business  operations  of the Fund on behalf of the members (the
"Members").  All of the Board are and will be  persons  who are not  "interested
persons" (as defined in the 1940 Act) with respect to the Fund.

DB Investment  Managers,  Inc.,  performing services as Topiary Fund Management,
(the  "Adviser")  serves as the  investment  adviser of the Fund  subject to the
ultimate  supervision  of and subject to any policies  established by the Board,
pursuant to the terms of an investment  management  agreement with the Fund (the
"Investment  Management  Agreement").  Pursuant  to  the  Investment  Management
Agreement,  the Adviser  provides  the Fund with  ongoing  investment  guidance,
policy direction,  and monitoring of the Fund. The Adviser is an indirect wholly
owned  subsidiary  of  Deutsche  Bank AG  ("Deutsche  Bank"),  an  international
commercial  and  investment  banking  group,  and is registered as an investment
adviser under the  Investment  Advisers Act of 1940,  as amended (the  "Advisers
Act").

THE TOPIARY MASTER FUND FOR BENEFIT PLAN INVESTORS (BPI) LLC
NOTES TO FINANCIAL STATEMENTS (CONTINUED)
FOR THE SIX MONTHS ENDED SEPTEMBER 30, 2007
--------------------------------------------------------------------------------


1.  ORGANIZATION (CONTINUED)

Generally,  initial  and  additional  applications  for  interests  by  eligible
investors  may be  accepted  at such times as the Fund may  determine.  The Fund
reserves the right to reject any  applications  for  interests in the Fund.  The
Fund from time to time may offer to repurchase Interests. These repurchases will
be made at such times and on such terms as may be  determined  by the Board,  in
its  complete and absolute  discretion.  On behalf of non-U.S.  Members the Fund
withholds and pays taxes on U.S. source income allocated from Investment Funds.

2.  SIGNIFICANT ACCOUNTING POLICIES

A.  PORTFOLIO VALUATION

The net asset  value of the Fund is  determined  by or at the  direction  of the
Adviser  as of the  last  business  day of each  month  in  accordance  with the
valuation  principles set forth below or as may be determined  from time to time
pursuant to policies established by the Board.

The net asset value of the Fund  equals the value of the Fund's  assets less the
Fund's liabilities,  including accrued fees and expenses. The Fund's investments
in the  Investment  Funds are considered to be illiquid and can only be redeemed
periodically.  The  Board has  approved  procedures  pursuant  to which the Fund
values its  investments in Investment  Funds at fair value.  In accordance  with
these  procedures,  fair  value as of each  month-end  ordinarily  is the  value
determined as of such month-end for each  Investment Fund in accordance with the
Investment  Fund's  valuation  policies  and  reported at the time of the Fund's
valuation.  As a general  matter,  the fair value of the Fund's  interest  in an
Investment Fund represents the amount that the Fund could  reasonably  expect to
receive from an Investment Fund if the Fund's interest were redeemed at the time
of the  valuation,  based on  information  reasonably  available at the time the
valuation is made and that the Fund  believes to be reliable.  In the event that
an  Investment  Fund does not report a  month-end  value to the Fund on a timely
basis,  the Fund would determine the fair value of such Investment Fund based on
the most  recent  value  reported  by the  Investment  Fund,  as well any  other
relevant  information  available at the time the Fund values its portfolio.  The
values assigned to these  investments are based on available  information and do
not necessarily  represent  amounts that might  ultimately be realized,  as such
amounts depend on future circumstances and cannot reasonably be determined until
the individual investments are actually liquidated.

B.  INCOME RECOGNITION AND SECURITY TRANSACTIONS

Interest income is recorded on an accrual basis.  Dividend income is recorded on
the   ex-dividend   date.   Realized  gains  and  losses  from  investment  fund
transactions  are  calculated  on the  identified  cost basis.  Investments  are
recorded on the effective date of the subscription in the Investment Fund.

2.  SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

C.  FUND COSTS

The Fund bears all expenses  incurred in its business  other than those that the
Adviser assumes.  The expenses of the Fund include,  but are not limited to, the
following:  all  costs and  expenses  related  to  investment  transactions  and
positions for the Fund's  account;  legal fees;  accounting  and auditing  fees;
custodial  fees;  costs of  computing  the  Fund's  net  asset  value;  costs of
insurance;  registration expenses;  due diligence,  including travel and related
expenses;  expenses of meetings of the Board and Members; all costs with respect
to  communications  to  Members;  and other types of expenses as may be approved
from time to time by the Board.

D.  INCOME TAXES

The Fund intends to operate and has elected to be treated as a  partnership  for
Federal  income tax  purposes.  Accordingly,  no  provision  for the  payment of
Federal,  state  or local  income  taxes  has  been  provided.  Each  Member  is
individually  required to report on its own tax return its distributive share of
the Fund's taxable income or loss. On behalf of the Fund's foreign members', the
Fund  withholds  and  pays  taxes on U.S.  source  income  and U.S.  effectively
connected  income,  if any,  allocated from underlying  Investment  Funds to the
extent such income is not exempted from withholdings  under the Internal Revenue
Code and Regulations  there under.  Such amounts recorded as  distributions  are
treated  by the  Members as  withholding  tax  credits  for  federal  income tax
purposes.  The  actual  amount of such  taxes is not  known  until all K-1s from
underlying  funds are received,  usually in the following tax year. Prior to the
final  determination,  the amount of the tax is estimated  based on  information
available.  The final  tax could be  different  from the  estimated  tax and the
difference could be significant.

E.  CASH AND CASH EQUIVALENTS

Cash and cash  equivalents  consist of monies on deposit at PNC Bank,  N.A.  The
Fund treats all  financial  instruments  that mature within three months as cash
equivalents.

F.  USE OF ESTIMATES

The preparation of financial statements in conformity with accounting principles
generally  accepted in the United States of America requires the Adviser to make
estimates  and  assumptions  that affect the amounts  reported in the  financial
statements  and  accompanying  notes.  The Adviser  believes  that the estimates
utilized  in  preparing  the Fund's  financial  statements  are  reasonable  and
prudent; however, actual results could differ from these estimates.

SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

G.  EXPENSE LIMITATION

Pursuant  to the Expense  Limitation  Agreement,  the Adviser has  contractually
agreed  to waive  fees  and/or  reimburse  the  Fund's  expenses  to the  extent
necessary to ensure that the Fund's annualized expenses (excluding the Incentive
Allocation,  if any) will not exceed  1.75%.  The  initial  term of the  Expense
Limitation Agreement is the first fiscal year of the Fund's operations, and will
be  automatically  renewed for each fiscal  year  thereafter  unless the Adviser
provides  written  notice to the Fund and the Master Fund of the  termination of
the  Expense  Limitation  Agreement  at  least  30 days  prior to the end of the
then-current term.

3.  MANAGEMENT FEE, RELATED PARTY TRANSACTIONS AND OTHER

The Adviser provides certain management and administration services to the Fund,

1.00% of the Fund's month end net assets,  including assets  attributable to the
Adviser (or its  affiliates)  and before giving effect to any repurchases by the
Fund.  The  Management  Fee  accrues  monthly  and is payable at the end of each
quarter. Management fee for the six months ended September 30, 2007 was $446,413
of which none was payable at period end.

The  Adviser  has   contractually   agreed  to  a  waiver  of  its  fees  and/or
reimbursement  of the Fund's expenses to the extent necessary so that the Fund's
annualized expenses do not exceed 1.75% ("Expense Limitation  Agreement") during
the six months through  September 30, 2007.  For the six months ended  September
30, 2007, the Adviser waived management fees of $225,836.

In   accordance   with  the   terms  of  the   administration   agreement   (the
"Administration  Agreement")  and with the approval of the Fund's  Board,  PFPC,
Inc.  (an  affiliate  of  PNC  Bank,   N.A.)  ("PFPC")   serves  as  the  Fund's
administrator  pursuant to the  administration  agreement  between  PFPC and the
Fund.  Under the  Administration  Agreement,  PFPC provides  administrative  and
accounting  services to the Fund. As compensation  for services set forth herein
that are rendered by PFPC during the term of this Agreement,  the Fund pays PFPC

pursuant to the Board services agreement.

Under this  agreement,  DIMA,  among  other  things:  drafts  Board  agendas and

attended. The chairman of the audit committee also receives an additional annual
fee of $2,000.  These  Board  members  are also  reimbursed  by the Fund for all
reasonable out of pocket expenses.

PFPC Trust Company (also an affiliate of PNC Bank,  N.A.) serves as custodian of

Under  the   terms   of  an  investor  servicing  agreement  (the  "Underwriting

advisers ("Investor Service Providers") to provide ongoing investor services and
account  maintenance   services  to  Members  that  are  their  customers.   The

                                       13

THE TOPIARY MASTER FUND FOR BENEFIT PLAN INVESTORS (BPI) LLC
NOTES TO FINANCIAL STATEMENTS (CONTINUED)
FOR THE SIX MONTHS ENDED SEPTEMBER 30, 2007
--------------------------------------------------------------------------------


5.  FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK (CONTINUED)

These include, but are not limited to, short selling activities,  writing option
contracts,  contracts for  differences,  and interest  rate,  credit default and
total return equity swaps contracts. The Fund's risk of loss in these Investment
Funds is limited to the value of these  investments  reported  by the Fund.  The
Fund itself does not invest in securities with off-balance sheet risk.

6.  CONCENTRATION OF RISK

The Master Fund invests  primarily in Investment  Funds that are not  registered
under  the 1940 Act and  invest  in and  actively  trade  securities  and  other
financial  instruments  using  different  strategies and investment  techniques,
including  leverage,  that may involve significant risks. These Investment Funds
may invest a high  percentage of their assets in specific  sectors of the market
in order to achieve a potentially  greater  investment  return. As a result, the
Investment Funds may be more susceptible to economic,  political, and regulatory
developments in a particular sector of the market, positive or negative, and may
experience increased volatility of the Investment Funds' net asset value.

Various risks are also  associated  with an  investment  in the Fund,  including
risks  relating to the  multi-manager  structure of the Fund,  risks relating to
compensation arrangements and risks relating to limited liquidity.

7.  GUARANTOR OBLIGATIONS AND INDEMNIFICATIONS

In the normal course of business,  the Fund enters into contracts that contain a
variety of warranties and representations that provide general indemnifications.
The Fund's maximum exposure under these  arrangements is unknown,  as this would
involve  future  claims  that may be made  against  the Fund  that  have not yet
occurred. However, the Fund's management expects the risk of loss to be remote.

8.  NEW ACCOUNTING PRONOUNCEMENTS

In July 2006,  the  Financial  Accounting  Standards  Board (the "FASB")  issued
Interpretation  No.  48,  "Accounting  for  Uncertainty  in  Income  Taxes  - an
interpretation of FASB Statement No. 109" ("FIN 48"). FIN 48 establishes for all
entities,  including pass-through entities such as the Fund, a minimum threshold
for financial statement  recognition of the benefit of positions taken in filing
tax  returns   (including   whether  an  entity  is  taxable  in  a   particular
jurisdiction),  and  requires  certain  expanded  tax  disclosures.  FIN  48  is
effective  for fiscal years  beginning  after  December  15, 2006,  and is to be
applied  to all open tax  years  as of the date of  effectiveness.  Based on the
Manager's analysis,  the determination has been made that the adoption of FIN 48
did not have an impact to the Fund's  financial  statements  upon adoption.  The
Manager  continually reviews the Fund's tax positions and such conclusions under
FIN 48 based on factors,  including, but not limited to, ongoing analyses of tax
laws, regulations and interpretations, thereof.

THE TOPIARY MASTER FUND FOR BENEFIT PLAN INVESTORS (BPI) LLC
PORTFOLIO PROXY VOTING POLICIES AND PROCEDURES; SEC FILINGS (UNAUDITED)
--------------------------------------------------------------------------------


The Fund invests substantially all of its assets in the securities of Investment
Funds, which are privately placed investment vehicles,  typically referred to as
"hedge  funds."  These  securities do not typically  convey  traditional  voting
rights to the holder and the occurrence of corporate governance or other notices
for this type of  investment  is  substantially  less than that  encountered  in
connection with registered equity  securities.  However,  to the extent the Fund
receives  notices or proxies from Investment Funds (or receives proxy statements
or similar notices in connection with any other portfolio securities);  the Fund
has  delegated  proxy voting  responsibilities  to the Adviser.  The Adviser has
adopted its own Proxy Voting Policies and Procedures ("Policies").  The Policies
address,  among other  things,  conflicts of interest that may arise between the
interests  of the Fund,  and the  interests  of the Adviser and its  affiliates,
including the Fund's principal underwriter.

A description of the Adviser's  Policies is available (i) without  charge,  upon
request, by calling the Fund toll-free at 1-888-262-0695,  and (ii) on the SEC's
website at WWW.SEC.GOV.

In addition,  the Fund is required to file new Form N-PX with its complete proxy
voting  record for the 12 months  ended June 30th,  no later than August 31st of
each year. The funds Form N-PX is available (i) without charge, upon request, by
calling the Fund toll free at  1-888-262-0695  and (ii) on the SEC's  website at
WWW.SEC.GOV.

The Fund files its complete schedule of portfolio  holdings with the SEC for the
first  quarter and the third quarter of each fiscal year on Form N-Q. The Fund's
Form N-Q filings are available on the SEC's website at WWW.SEC.GOV.  Those forms
may be reviewed and copied at the SEC's Public Reference Room in Washington D.C.
Information  on the  operation of the Public  Reference  Room may be obtained by
calling 1-800-SEC-0330.
