THE TOPIARY MASTER FUND FOR BENEFIT PLAN INVESTORS (BPI) LLC
NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
--------------------------------------------------------------------------------

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, 2005,
the investment by the Offshore Fund constitutes 86% 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  14%,
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 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"). At least a majority 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. (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
("Advisers Act").

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

1. ORGANIZATION (CONTINUED)

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  investments to the extent
such income is not exempted from  withholdings  under the Internal  Revenue Code
and Regulations there under. Such amounts are treated as withholding tax credits
for federal  income tax  purposes.  The actual amount of such taxes is not known
until all K-1's 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 PFPC Trust  Company.
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.

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 Fund pays the

1.00% of the Fund's month end net assets,  including assets  attributable to the

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 period through March 31, 2006. For the period, the Adviser waived management
fees of $1,916 for the expenses the Fund accrued.

In accordance with the terms of the  administration  agreement  ("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 (Administration  Agreement").
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 a fee for
services rendered.

The Fund has entered into an investor services agreement with PFPC, whereby PFPC
provides  investor  services  and transfer  agency  functions  for the Fund.  As
compensation  for services set forth herein that are rendered by PFPC during the
term of this Agreement, the Fund pays PFPC a fee for services rendered.

The Adviser has also retained one of its affiliates,  Investment Company Capital
Corporation  ("ICCC"),  to provide  sub-administration  services pursuant to the
Board services agreement. Under this agreement, ICCC, among other things: drafts
Board agendas and resolutions;  prepares Board materials;  communicates with the
Directors;  and drafts Board-meeting minutes. For the services performed by ICCC
pursuant  to this  Agreement,  the  Adviser  compensates  ICCC at no  additional
expense to the Fund.

Each  Board  member  who is  not  an  employee  of  the  Adviser,  or one of its
affiliates,  receives an annual  retainer of $8,000 plus a fee for each  meeting
attended. The chairman of the audit committee also receives an additional annual
fee of $1,000.  These  Board  members  are also  reimbursed  by the Fund for all
reasonable out of pocket expenses.

the Fund's assets and provides custodial services to the Fund.

3. MANAGEMENT FEE, RELATED PARTY TRANSACTIONS AND OTHER (CONTINUED)

Under  the  terms  of  an  investor  servicing  agreement  (the  "  Underwriting
Agreement") between the Fund and Scudder Distributors, Inc. (the "Distributor"),
the Distributor is authorized to retain brokers,  dealers and certain  financial
advisers ("Investor Service Providers") to provide ongoing investor services and
account  maintenance   services  to  Members  that  are  their  customers.   The
Distributor  bears all of its  expenses of  providing  distribution  services as
described under the Underwriting Agreement.

4. SECURITY TRANSACTIONS

As of September 30, 2005, the Fund had investments in Investment  funds, none of
which were related parties.  Aggregate purchases of Investment funds amounted to
$14,920,000 and aggregate  sales of Investment  funds amounted to $7,545,689 for
the period ended September 30, 2005.

At September 30, 2005, the estimated cost of investments  for Federal income tax
purposes  was  $58,415,217.  As of that date,  net  unrealized  appreciation  on
investments  was  estimated  to  be  $5,356,387,  made  up of  gross  unrealized
appreciation on investments of $5,875,182 and gross  unrealized  depreciation on
investments of $518,795.

5. FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK

In the normal course of business, the Investment funds in which the Fund invests
trade various financial instruments and enter into various investment activities
with  off-balance  sheet risk.  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 November 2002, the Financial  Accounting Standards Board ("FASB") issued FASB
Interpretation  No. 45, GUARANTOR'S  ACCOUNTING AND DISCLOSURE  REQUIREMENTS FOR
GUARANTEES,   INCLUDING  INDIRECT  GUARANTEES  OF  INDEBTEDNESS  OF  OTHERS,  AN
INTERPRETATION  OF FASB  STATEMENTS  NO. 5, 57, AND 107 AND  RESCISSION  OF FASB
INTERPRETATION  NO. 34 ("FIN 45"). FIN 45 requires  certain  disclosure that was
intended to improve the  transparency  of the  financial  statement  information
about a  guarantor's  obligations  and  liquidity  risks  related to  guarantees
issued.  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. SUBSEQUENT EVENT

In October,  2005, the Fund effected subscriptions from Members of $5,401,325 of
which none were received prior to October 1, 2005.

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.

                        ADDENDUM TO FINANCIAL STATEMENTS
     For the Six Month Period from April 1, 2005 through September 30, 2005

BOARD REVIEW OF THE CURRENT INVESTMENT MANAGEMENT AGREEMENT

      The Board of Directors of the Fund (the "Board") presently consists of
three directors, all of whom are independent, or non-interested, directors (the
"Independent Directors"). The Board considers matters relating to the investment
management agreement (the "Investment Management Agreement") between DB
Investment Managers, Inc. ("DBIM") and The Topiary Master Fund for Benefit Plan
Investors (BPI) LLC (the fund in which the Fund invests) throughout the year. On
an annual basis, the Board specifically considers whether to approve the
continuance of the Investment Management Agreement for an additional one-year
period. In considering the approval of the Investment Management Agreement, the
Board considers the terms of such agreement and the incentive compensation
payable to DBIM under the Fund's operating agreement.

      At a meeting held on September 9, 2005 (the "September 9 Meeting"), the
Board, comprised of the Independent Directors, unanimously approved the
continuance of the Investment Management Agreement.

      At the September 9 Meeting, the Board reviewed, among other information, a
memorandum from outside counsel outlining factors to be considered in evaluating
investment management and underwriting arrangements, written and oral reports
and compilations from DBIM, including comparative data as to investment
performance, advisory fees and other expenses of peer funds, and expense
comparisons of the Fund over a number of time periods. The Board also reviewed
an Investment Management Group Review, which detailed the current and future
business plans of DBIM and its affiliate DB ARS, and a memorandum from DBIM
detailing the possible incidental benefits to DBIM resulting from the Investment
Management Agreement. In addition, the Board took into account information
provided at previous meetings and other knowledge about DBIM the Board had
accumulated over the years.

      In approving the continuance of the Investment Management Agreement, the
Board of Directors considered the following factors, among others:

      NATURE, EXTENT AND QUALITY OF SERVICES. The Board examined the nature,
extent and quality of the investment management services provided and to be
provided to the Fund by DBIM and its affiliates. The Board considered the terms
of the Investment Management Agreement and the experience and qualifications of
DBIM and its personnel. The Board also considered DBIM's attention to compliance
matters and the absence of material regulatory issues relating to the Fund.
Further, the Board considered DBIM's past organizational changes and turnover in
its personnel, the overall commitment of DBIM to the Fund, and the general
financial condition, resources and reputation of DBIM and its parent. The Board
was generally satisfied with the nature, extent and quality of the investment
management services provided to the Fund.



      INVESTMENT PERFORMANCE. The Board considered performance information
provided by DBIM over a number of time periods. DBIM also provided the Directors
with comparative performance information of peer funds that they had requested.
The Board also reviewed the ways in which the investment strategies employed by
DBIM contributed to the Fund's investment performance. After considering all
factors deemed appropriate, the Board concluded that the Fund's performance
supported the continuance of the Investment Management Agreement.

      COSTS OF SERVICES. The Board examined the expenses paid by the Fund,
together with the expense information concerning other similar funds. The Board
also noted that DBIM had provided a 1.75% cap on the annual operating expenses
of the Fund (exclusive of any incentive fee payments). Based on this
information, the Board concluded that the investment management fee and expense
ratio of the Fund were generally competitive.

      PROFITS REALIZED BY DBIM. DBIM advised the Board that its investment
advisory arrangement with the Fund was not profitable at the current time, due
primarily to the current size of the Fund and the agreement to cap operating
expenses provided by DBIM as described above. Pursuant to the agreement to limit
operating expenses, the entire advisory fee of $227,311 for the year ended March
31, 2005 was reimbursed by DBIM. Pursuant to the operating agreement, the Fund
paid to DBIM an incentive allocation of $57,188 for the year ended March 31,
2005. The Board reviewed this information and concluded that any profit expected
to be earned by DBIM from the Investment Management Agreement under the current
circumstances was limited, which warranted the continuance of these advisory
arrangements.

      ECONOMIES OF SCALE. The Board considered the extent to which economies of
scale would be realized as the Fund grows and whether fee levels reflect these
economies of scale for the benefit of Fund investors. The Fund had net assets of
approximately $69 million at August 31, 2005 and the Board did not identify any
economies of scale realized by DBIM at this asset level. The Board and DBIM
agreed that the issue would be reviewed in the future to the extent that the
Fund's assets increase.

      OTHER BENEFITS TO DBIM. The Board recognized that DBIM might realize
others benefits from its relationship with the Fund, including receipt of fees
by affiliates performing services for the Fund. These other potential benefits
did not, however, affect the Board's decision to approve of the continuance of
the Investment Management Agreement.

      Based on an evaluation of all factors deemed relevant, including the
factors described above, the Board concluded that the Agreement should be
continued through September 30, 2006.


                                                                               2
