                               September 30, 2007

1. ORGANIZATION

Old Mutual Absolute Return Master Fund, L.L.C. (the "Fund") (formerly Old Mutual
2100  Absolute  Return  Master  Fund,  L.L.C.) is a Delaware  limited  liability
company that is registered under the Investment  Company Act of 1940, as amended
(the  "1940  Act")  as  a  non-diversified,  closed-end,  management  investment
company, which was formed on April 25, 2006 and commenced operations on November
1, 2006. The Fund is a master fund in a  master/feeder  structure into which its
feeder  funds,  Old Mutual  Absolute  Return Fund,  L.L.C.  (the "Feeder  Fund")
(formerly Old Mutual 2100 Absolute Return Fund,  L.L.C.) and Old Mutual Absolute
Return  Institutional Fund, L.L.C. (the  "Institutional  Feeder Fund") (formerly
Old Mutual 2100 Absolute Return Institutional Fund, L.L.C.), (collectively,  the
"Feeders"  or  "Members"),  invest  substantially  all of  their  assets.  As of
September 30, 2007, the Feeder Fund's  investment in the Fund represented  89.7%
of Members'  Capital,  the  Institutional  Feeder Fund's  investment in the Fund
represented 1.3% of Members' Capital and an affiliate of the Adviser (as defined
in Note 3) had an  investment  in the Fund which  represented  9.0% of  Members'
Capital.

The Fund employs a "fund of funds"  investment  program  that  enables  eligible
investors,  through one investment, to participate in the investment programs of
a  professionally  selected group of asset managers without being subject to the
high minimum investment  requirements that many asset managers typically impose.
The Fund is similar to a private  investment fund in that it is actively managed
and  interests  in the Feeders  ("Interests")  are sold solely to high net worth
individual  and  institutional  investors,  but differs  from a typical  private
investment  fund in that it has  registered as an  investment  company under the
1940 Act.

The Fund's investment  objective is to seek to generate attractive returns while
attempting  to reduce  volatility.  The Fund  invests  its assets  primarily  in
private investment funds, joint ventures, investment companies and other similar
investment  vehicles  ("Portfolio  Funds") that are managed by a select group of
portfolio managers ("Portfolio  Managers") that invest in a variety of financial
markets and utilize a broad range of alternative investment strategies.

2. SIGNIFICANT ACCOUNTING POLICIES

The Fund's  financial  statements  are prepared in  conformity  with  accounting
principles  generally accepted in the United States of America. The following is
a summary of the significant accounting policies followed by the Fund:

A. 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.  Actual  results  could  differ from these
estimates.


                                                                               8

              Notes to Financial Statements (unaudited) (continued)

2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

B. Portfolio Valuation and Investment Transactions

The net asset value of the Fund is  determined  by or at the  discretion  of the
Adviser as of the close of  business  as of the end of each month in  accordance
with the valuation principles as may be determined from time to time pursuant to
policies  established  by the Fund's Board of Managers  (the  "Board").  The net
asset  value  of the Fund is based  primarily  on the fair  value of each of its
interests in Portfolio  Funds.  Ordinarily,  these values are  determined by the
Portfolio  Managers of the  Portfolio  Funds in  accordance  with the  Portfolio
Funds'  valuation  policies  and as reported  by the  Portfolio  Managers.  As a
general  matter,  the fair  value of the Fund's  interest  in a  Portfolio  Fund
represents the amount that the Fund could reasonably  expect to receive from the
Portfolio  Fund if the Fund's  interest  were redeemed at the time of valuation,
based on information  reasonably available at the time the valuation is made and
that the Fund believes to be reliable.

The Fund's  valuation  procedures  require the Adviser to consider  all relevant
information available at the time the Fund values its assets. The Adviser or, in
certain  cases,  the Fund's  Board,  will  consider  such  information,  and may
conclude in certain  circumstances that the information  provided by a Portfolio
Manager does not represent the fair value of the Fund's interests in a Portfolio
Fund.  Following  procedures  adopted by the Board,  in the  absence of specific
transaction activity in interests in a particular Portfolio Fund, the Fund could
consider whether it was appropriate, in light of all relevant circumstances,  to
value such a position at the Portfolio Fund's net asset value as reported at the
time of  valuation,  or  whether  to adjust  such  value to reflect a premium or
discount to net asset value.  Any such decision must be made in good faith,  and
subject to the review and supervision of the Board.

Realized gains and losses from Portfolio Fund transactions are calculated on the
identified  cost basis.  Investments  are recorded on the effective  date of the
subscription to or redemption from the Portfolio Fund.

Interest  income is recorded on an accrual basis and consists of interest earned
on cash.

C. Income Taxes

Counsel to the Fund  rendered an opinion that the Fund will be  classified  as a
partnership  and not as an association  taxable as a corporation for Federal tax
purposes. Counsel to the Fund also rendered its opinion that, under a "facts and
circumstances"  test,  the  Fund  will  not be  treated  as a  "publicly  traded
partnership"  taxable  as a  corporation.  Accordingly,  the Fund  should not be
subject to Federal income tax, and each Member will be required to report on its
own annual tax return such  Member's  distributive  share of the Fund's  taxable
income or loss.


                                                                               9

2. SIGNIFICANT ACCOUNTING POLICIES (CONCLUDED)

D. Distribution Policy

The Fund has no present  intention of making periodic  distributions  of its net
investment income or capital gains, if any, to Members. The amount and frequency
of  distributions,  if any,  will be  determined  in the sole  discretion of the
Board.

E. Distributions from Portfolio Funds

Distributions  from Portfolio  Funds will be classified as investment  income or
realized gains in the Statements of Operations, or alternatively,  as a decrease
to the cost of the investments based on the U.S. income tax  characteristics  of
the  distribution  if such  information  is  available.  In cases  where the tax
characteristics  are not  available,  such  distribution  will be  classified as
investment income.

F. Cash

As of September 30, 2007,  cash consists of an investment in a money market fund
affiliated  with the  Administrator  (as defined in Note 3). The  investment  is
carried at cost, which approximates market value.

3. MANAGEMENT FEE, RELATED PARTY TRANSACTIONS AND OTHER

Larch Lane  Advisors  LLC (the  "Adviser")  (formerly,  2100 Larch Lane LLC),  a
Delaware limited liability company, serves as the investment adviser of the Fund
pursuant to an  agreement  dated  October  13,  2006.  The  initial  term of the
agreement  expires on October 13, 2008 and may be  continued in effect from year
to year  thereafter  if its  continuance  is approved  annually.  The Adviser is
registered as an investment  adviser under the Investment  Advisers Act of 1940,
as amended (the "Advisers  Act").  LLA Holdings,  LLC, the special member of the
Adviser, owns 81.25% of the Adviser and is an indirect majority-owned subsidiary
of Old Mutual (US) Holdings, Inc. ("OMUSH"),  which is a wholly-owned subsidiary
of Old Mutual plc, a London exchange  listed  international  financial  services
firm.  OMUSH is also a member of the Fund.  OMUSH did not contribute  during the
period and has Members'  capital of  $1,068,597  as of September  30, 2007.  The
Adviser is responsible for developing,  implementing  and supervising the Fund's
investment program and providing day-to-day management services to the Fund.

Under the  agreement  with the  Adviser,  the Fund  does not pay any  investment
management fee to the Adviser.  However,  under the agreement,  in the event the
Adviser  ceases to serve as the  Adviser to each  Feeder,  the Master Fund would
then be subject to a fee that is calculated  and payable in accordance  with the
lowest  annual  rate that had most  recently  been  charged by the  Adviser to a
Feeder.


                                                                              10

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

The Fund and the Feeder Fund have entered into a  Master/Feeder  Agreement dated
October 13,  2006 and the Fund and the  Institutional  Feeder Fund have  entered
into  a  Master/Feeder  Agreement  dated  February  8,  2007.  Pursuant  to  the
agreement, the Fund and the Feeders will each have the same investment objective
and  substantially the same investment  policies.  The Feeders will pursue their
investment  objectives  by investing on an ongoing  basis  substantially  all of
their investable  assets in the Fund in exchange for limited  liability  company
interests in the Fund. The Master/Feeder Agreements will remain in effect unless
terminated by the Fund or the Feeders.

The Fund is managed by the Board of Managers  (the  "Board")  and each member of
the Board who is not an "interested manager" of the Fund, as defined by the 1940
Act (the  "Independent  Managers"),  is entitled to an annual retainer of $2,500
and will be reimbursed by the Fund for travel-related  expenses. The Independent
Managers  of the  Board are  Gerald  Hellerman,  Paul D.  Malek,  and  George W.
Morriss.

Pursuant to an  administrative  services  agreement  dated  October 13, 2006 and
amended   February  8,  2007,  SEI   Investments   Global  Funds  Services  (the
"Administrator"),  provides various administrative  services to the Fund and the
Feeders,  including fund accounting,  investor accounting and taxation services,
maintaining  the  register  of the Fund and  generally  performing  all  actions
related to the issuance and transfer of  Interests;  reviewing  and,  subject to
approval  by the Fund,  accepting  subscriptions  for  Interests  and  accepting
payment  therefore;  performing all acts related to the repurchase of Interests;
and  performing  all other clerical  services  necessary in connection  with the
administration  of the  Fund.  The  initial  term of the  agreement  expires  on
November 1, 2009 and may be continued in effect from year to year  thereafter if
its continuance is approved annually.

In consideration for the services provided by the  Administrator,  the Fund pays
the Administrator a monthly fee calculated and assessed monthly in arrears at an
annualized  rate of 0.01% of the Fund's net assets,  subject to a minimum annual
fee of $5,000.

SEI Private  Trust  Company (the  "Custodian")  serves as the  custodian for the
assets  of the  Fund  pursuant  to an  agreement  dated  October  13,  2006.  In
consideration  for the  services  provided by the  Custodian,  the Fund pays the
Custodian  a monthly  fee at an  annualized  rate of  0.0075%  of the Fund's net
assets,  subject to a minimum annual fee of $1,500. The agreement will remain in
effect unless terminated by the Fund or the Custodian.

4. FUND EXPENSES

The Fund bears its own operating expenses. These operating expenses include, but
are not limited to: all investment-related  expenses (including, but not limited
to, fees paid directly or indirectly to Portfolio  Managers,  investment-related
interest  expenses,  all  costs  and  expenses  directly  related  to  portfolio
transactions  and  positions,  transfer taxes and premiums and taxes withheld on
foreign  dividends);  any  non-investment  related  interest  expense;  fees and
disbursements of any attorneys or accountants engaged


                                                                              11

              Notes to Financial Statements (unaudited) (continued)

4. FUND EXPENSES (CONCLUDED)

on behalf of the Fund;  entity-level  taxes,  audit and tax preparation fees and
expenses;  administrative expenses and fees of the Fund; custody expenses of the
Fund;  the costs of an errors and  omissions/directors  and  officers  liability
insurance and a fidelity bond for the Fund; fees and travel-related  expenses of
the Board of the Fund who are not  employees of the Adviser or any  affiliate of
the  Adviser;   all  costs  and  charges  for  equipment  or  services  used  in
communicating   information   regarding  the  Fund's   transactions   among  the
sub-Adviser  and  any  custodian  or  other  agent  engaged  by  the  Fund;  any
extraordinary  expenses; and such other expenses as may be approved from time to
time by the Board.

The Fund also indirectly  bears fees and expenses of the Portfolio  Funds.  Each
Portfolio Manager  generally  receives a management fee and a performance fee or
allocation  with respect to the assets of Portfolio  Funds that it manages.  The
amount of these fees and allocations  varies among Portfolio  Managers,  but the
management  fees are generally  expected to be between  1.0%-2.0%,  on an annual
basis, of the total assets managed by a Portfolio  Manager,  and the performance
fees or  allocations  are  generally  expected to be between  15%-25% of the net
capital appreciation (if any) in the assets managed by a Portfolio Manager.

5. INITIAL OFFERING COSTS AND ORGANIZATION EXPENSES

The  Fund  incurred  initial  offering  costs  totaling   approximately  $14,725
comprised principally of legal costs pertaining to the preparation of the Fund's
offering   documents.   These  costs  are  being   amortized  over  the  initial
twelve-month period which expired on October 31, 2007.

Costs incurred in connection with the  organization of the Fund were expensed at
April 25, 2006,  the  inception  date.  The Adviser paid the costs in connection
with  the  organization  of  the  Fund  and  agreed  to  absorb  $15,000  of the
organization  costs. The Fund incurred  $109,900 in organization  costs and will
repay the Adviser.

6. BORROWINGS

The  Fund is  authorized  to  borrow  money  for  investment  purposes,  to meet
repurchase requests and for cash management purposes. Borrowings by the Fund are
subject to a 300% asset coverage requirement under the 1940 Act. Portfolio Funds
that  are  not  registered   investment   companies  are  not  subject  to  this
requirement.  The Fund had no borrowings  during the period ended  September 30,
2007.


                                                                              12

              Notes to Financial Statements (unaudited) (continued)

7. CAPITAL ACCOUNTS AND ALLOCATIONS

The Fund maintains a separate  capital account for each Member.  The net profits
or net losses of the Fund (including,  without limitation,  net realized gain or
loss and the net change in unrealized appreciation or depreciation of securities
positions) are credited to or debited against the capital accounts of Members as
of the end of each fiscal period in accordance with their respective  investment
percentages for the period.  Each Member's  investment  percentage is determined
each fiscal  period by  dividing,  as of the  commencement  of the  period,  the
balance  of the  Member's  capital  account  by the sum of the  balances  of the
capital accounts of all Members.

A fiscal  period  begins on the day after the last day of the  preceding  fiscal
period and ends at the close of  business on the first to occur of: (i) the last
day of each  fiscal  year (March  31);  (ii) the last day of each  taxable  year
(December 31); (iii) the day preceding the date as of which any contributions to
the capital of the Fund is made;  (iv) any day as of which the Fund  repurchases
the Interest (or portion thereof) of any Member;  or (v) any day as of which any
amount is credit to or debited from the capital account of any Member other than
an amount to be credited to or debited from the capital  accounts of all Members
in accordance with their respective investment percentages.

8. SUBSCRIPTIONS AND REDEMPTIONS OF INTERESTS

The Board  may admit one or more  Members  generally  at the  beginning  of each
month;  provided,  however,  that the Fund may, in the  discretion of the Board,
admit Members more or less frequently.

No Member or other person holding an Interest or portion  thereof shall have the
right to require the Fund to repurchase  that Interest or portion  thereof.  The
Board,  in its  sole  discretion  and on such  terms  and  conditions  as it may
determine,  may cause  the Fund to  repurchase  Interests  or  portions  thereof
pursuant to written  tenders.  However,  the Fund shall not offer to  repurchase
Interests on more than four occasions during any one fiscal year;  provided that
offers made more than  semi-annually  in any taxable year shall only be accepted
if Members  give at least 65 days' notice of their  acceptance  in any tax year,
unless  it has  consulted  with  counsel  to the Fund and  determined  that more
frequent offers would not cause any adverse tax  consequences to the Fund or the
Members.  In  determining  whether to cause the Fund to repurchase  Interests or
portions thereof pursuant to written  tenders,  the Board shall consider,  among
other things, the recommendation of the Adviser.

9. FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK

In the normal course of business,  the Portfolio 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 options contracts,  and swap contracts.  The Fund's
risk of loss in the Portfolio Funds is limited to the value of these investments
reported by the Portfolio Funds.


                                                                              13



                 Old Mutual Absolute Return Master Fund, L.L.C.
              Notes to Financial Statements (unaudited) (continued)

10. INDEMNIFICATIONS

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

11. CONCENTRATION OF RISK

The Fund invests  primarily in Portfolio Funds that are not registered under the
1940 Act which  invest in and  actively  trade  securities  and other  financial
instruments  using  different  strategies and investment  techniques,  including
leverage,  which may involve significant risks. These Portfolio 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 Portfolio
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 Portfolio Funds' net asset value.

The Fund may invest in a limited number of Portfolio Funds.  Such  concentration
may result in additional  risk. The Portfolio Funds may enter into the following
transactions and certain of the related risks are described below:

A. Short Sales

Short sales are sales of securities  that are not owned or that are not intended
for  delivery  and the seller will  therefore  be  obligated  to  purchase  such
securities at a future date. The value of the open short position is recorded as
a liability, and the seller records unrealized gain or loss to the extent of the
difference  between  the  proceeds  received  and the  value of the  open  short
position.  A realized gain or loss is recorded when the short position is closed
out. By entering into short sales, the seller bears the market risk of increases
in value of the security sold short in excess of the proceeds received.

B. Swap Agreements

A swap  contract is a contract  under which two parties  agree to make  periodic
payments to each other based on the value of a  security,  a specified  interest
rate,  an index or the value of some  other  instrument  applied  to a stated or
"notional" amount.  Swaps are subject to various types of risk, including market
risk, liquidity risk, counterparty credit risk, legal risk and operations risk.

C. Options

The  Portfolio  Funds  may buy or write  put and  call  options  through  listed
exchanges and the over-the-counter  market. The buyer has the right, but not the
obligation, to purchase (in the case of a call option)


                                                                              14



                 Old Mutual Absolute Return Master Fund, L.L.C.
              Notes to Financial Statements (unaudited) (continued)

11. CONCENTRATION OF RISK (CONTINUED)

or sell  (in the  case of a put  option)  a  specified  quantity  of a  specific
security  or  other  underlying  asset  at a  specified  price  prior to or on a
specified  expiration  date.  The  writer of an option is exposed to the risk of
loss if the market price of the underlying  asset declines (in the case of a put
option) or increases (in the case of call  option).  The writer of an option can
never  profit  by more  than  the  premium  paid by the  buyer  but can  lose an
unlimited amount.

D. Futures Contracts

The  Portfolio  Funds may use futures  contracts  for  hedging  and  non-hedging
purposes.  Upon  entering  into a  futures  contract,  the  Portfolio  Funds are
required to deposit an amount ("initial  margin") equal to a certain  percentage
of the contract  value.  Pursuant to the contract,  the Portfolio Funds agree to
receive  from,  or pay to,  the  broker  an  amount  of cash  equal to the daily
fluctuation in the value of the contract. Such receipts or payments are known as
"variation  margin" and are recorded by the Portfolio Funds as unrealized  gains
or losses.  When the contract is closed,  the Portfolio  Funds record a realized
gain or loss equal to the  difference  between the value of the  contract at the
time it was  opened  and the  value at the time when it was  closed.  The use of
futures transactions  includes the risk of imperfect correlation in movements in
the price of futures  contracts,  interest rates,  underlying hedged assets, and
the  possible  inability  of the  counterparties  to meet  the  terms  of  their
contracts.

E. Leverage Transactions

In order to obtain more  investable  cash,  the Portfolio  Funds may use various
forms of leverage including  purchasing  securities on margin. Such leverage may
allow the Portfolio Funds to increase partners' capital at a greater rate during
favorable  markets,  but also may lead to a more  rapid  decrease  in  partners'
capital in unfavorable  markets. A margin transaction  consists of purchasing an
investment  with money  loaned by a broker and agreeing to repay the broker at a
later  date.  Interest  expense on the  outstanding  margin  balance is based on
market rates at the time of the borrowing.

F. Forward Foreign Currency Contracts

The Portfolio Funds may enter into forward foreign currency  contracts.  Forward
contracts are  over-the-counter  contracts  for delayed  delivery of currency in
which  the buyer  agrees to buy and the  seller  agrees to  deliver a  specified
currency at a specified price on a specified date.  Because the terms of forward
contracts are not standardized,  they are not traded on organized  exchanges and
generally can be  terminated or closed-out  only by agreement of both parties to
the contract. All commitments are marked to market on each valuation date at the
applicable  foreign  exchange rate and any resulting  unrealized gain or loss is
recorded on such date.  The Portfolio Fund realizes gains and losses at the time
forward  contracts are  extinguished  or closed upon entering into an offsetting
contract.


                                                                              15

              Notes to Financial Statements (unaudited) (continued)

11. CONCENTRATION OF RISK (CONTINUED)

G. Repurchase Agreements

Repurchase  agreements are  agreements  under which a Portfolio Fund or the Fund
purchases securities from a bank that is a member of the Federal Reserve System,
a foreign bank or a securities  dealer that agrees to repurchase  the securities
from the  Portfolio  Fund at a higher price on a designated  future date. If the
seller under a repurchase  agreement  becomes  insolvent,  the Portfolio  Fund's
right to  dispose  of the  securities  may be  restricted,  or the  value of the
securities may decline before the Portfolio Fund is able to dispose of them.

H. Reverse Repurchase Agreements

Reverse repurchase  agreements are a form of borrowing that involves a sale of a
security by a Portfolio  Fund to a bank or  securities  dealer and the Portfolio
Fund's  simultaneous  agreement to  repurchase  that  security for a fixed price
(reflecting a market rate of interest) on a specific  date.  These  transactions
involve a risk that the other party to a reverse  repurchase  agreement  will be
unable or unwilling to complete the  transaction as scheduled,  which may result
in losses to the Portfolio Fund. Reverse  repurchase  transactions are a form of
leverage  and may  increase  the  volatility  of a Portfolio  Fund's  investment
portfolio.

I. Lending Portfolio Securities

Portfolio Funds may lend securities held in their portfolios to brokers, dealers
and other  financial  institutions  needing  to borrow  securities  to  complete
certain  transactions.  The lending  Portfolio  Fund continues to be entitled to
payments in amounts  equal to the  interest,  dividends  or other  distributions
payable on the loaned securities which afford it an opportunity to earn interest
on the amount of the loan and on the  loaned  securities'  collateral.  Loans of
portfolio  securities by a Sub-Manager  may not exceed 33-1/3% of the value of a
Portfolio  Account's  total assets,  and, in respect of such  transactions,  the
Portfolio  Fund will receive  collateral  consisting  of cash,  U.S.  Government
Securities  or  irrevocable  letters of credit which will be  maintained  at all
times in an amount  equal to at least 100% of the  current  market  value of the
loaned  securities.  A Portfolio Fund might  experience  loss if the institution
with which the  Portfolio  Fund has  engaged  in a  portfolio  loan  transaction
breaches its agreement with the Portfolio Fund.

J. When-Issued and Forward Commitment Securities

Portfolio  Managers  may  purchase  securities  on a  when-issued  basis and may
purchase  or sell  securities  on a forward  commitment  basis in order to hedge
against  anticipated  changes in interest rates and prices.  These  transactions
involve a commitment  by a Portfolio  Fund to purchase or sell  securities  at a
future date  (ordinarily  one or two months later).  The price of the underlying
securities, which is generally expressed in terms of yield, is fixed at the time
the commitment is made, but delivery and payment for


                                                                              16

              Notes to Financial Statements (unaudited) (continued)

11. CONCENTRATION OF RISK (CONCLUDED)

the securities takes place at a later date. No income accrues on securities that
have been purchased  pursuant to a forward  commitment or on a when-issued basis
prior to delivery to the  Portfolio  Fund.  When-issued  securities  and forward
commitments  may be sold  prior to the  settlement  date.  If a  Portfolio  Fund
disposes of the right to acquire a when-issued security prior to its acquisition
or disposes of its right to deliver or receive against a forward commitment,  it
may incur a gain or loss.

There is a risk that  securities  purchased  on a  when-issued  basis may not be
delivered  and that the purchaser of  securities  sold by a Portfolio  Fund on a
forward basis will not honor its purchase obligation. In such cases, a Portfolio
Fund may incur a loss.

K. Restricted and Illiquid Investments

Portfolio Funds may invest in restricted  securities and other investments which
are illiquid.  Restricted  securities are securities that may not be sold to the
public without an effective  registration  statement under the Securities Act of
1933 or, if they are  unregistered,  may be sold only in a privately  negotiated
transaction or pursuant to an exemption from registration.  The Fund's interests
in  unregistered   Portfolio  Funds  are  themselves  illiquid  and  subject  to
substantial  restrictions  on transfer.  The Fund may  liquidate an interest and
withdraw from an  unregistered  Portfolio  Fund  pursuant to limited  withdrawal
rights.  The illiquidity of these interests may adversely  affect the Fund if it
is unable to withdraw  its  investment  in a Portfolio  Fund  promptly  after it
determines to do so.

L. Liquidity

The Portfolio Funds provide for periodic  redemptions,  with lock-up  provisions
ranging from one year to three years from the initial investment.  The liquidity
provisions  shown  on the  Schedule  of  Investments  apply  after  the  lock-up
provisions.

12. INVESTMENT TRANSACTIONS

For the period  ended  September  30, 2007,  the Fund  redeemed  investments  in
Portfolio Funds in the amount of $200,950.

13. INVESTMENTS

As of September 30, 2007, the Fund had investments in eighteen  Portfolio Funds,
none of which were related parties.

The Fund limits its  investment  position in any one Portfolio Fund to less than
5% of the Portfolio Fund's outstanding voting securities, absent an order of the
Securities  and  Exchange  Commission  (the "SEC") (or  assurances  from the SEC
staff) under which the Fund's contribution and withdrawal of capital from a


                                                                              17



                 Old Mutual Absolute Return Master Fund, L.L.C.
              Notes to Financial Statements (unaudited) (continued)

13. INVESTMENTS (CONTINUED)

Portfolio  Fund in which it holds 5% or more of the  outstanding  interests will
not be subject to various 1940 Act prohibitions on affiliated transactions.  The
Fund also is not  required  to adhere to this 5%  investment  limitation  to the
extent that it relies on certain SEC rules that provide exemptions from 1940 Act
prohibitions on affiliated  transactions.  However, to facilitate investments in
smaller Portfolio Funds deemed attractive by the Adviser,  the Fund may purchase
non-voting securities of, or waive its right to vote its interests in, Portfolio
Funds.  Although the Fund may hold  non-voting  interests,  the 1940 Act and the
rules and regulations  thereunder may nevertheless require the Fund to limit its
position in any one Portfolio  Fund, if  investments  in a Portfolio Fund by the
Fund will  equal or exceed 25% of the  Portfolio  Fund's  assets,  or such lower
percentage  limit  as may be  determined  by the Fund in  consultation  with its
counsel.  These  restrictions could change from time to time as applicable laws,
rules or interpretations thereof are modified.

Portfolio Funds' Investment Strategies:

CAPITAL STRUCTURE ARBITRAGE

Capital Structure  Arbitrage managers will typically buy "long" and sell "short"
different  classes of securities of the same issuer in anticipation of profiting
from the  relative  mispricing  between  them.  Convertible-bond  arbitrage  and
equity-warrant arbitrage are forms of balance-sheet arbitrage.

COMMODITY TRADING ADVISOR

Commodity Trading Advisor managers will typically have portfolio funds employing
this particular strategy purchase and sell local or foreign currency,  commodity
futures and options or such futures contracts based on supply and demand factors
affecting   price  within  each  market.   Certain   Portfolio  funds  also  use
commodity-related equities to implement their strategies.

EQUITY LONG BIAS

Equity Long Bias managers  will  typically  have  portfolios of long equities as
well as some short  positions.  Unlike variable bias or market  neutral,  Equity
Long Bias  managers  are  expected  to average at least 70% net long (gross long
positions minus short positions).  Leverage may be employed,  though likely at a
lower amount than market neutral or variable bias strategies. This strategy will
show a high degree of  correlation to equity  markets,  as the majority of their
profits will stem from their long  positions.  Short positions will typically be
used to hedge though may also be opportunistic in nature.

EQUITY MARKET NEUTRAL

Equity Market Neutral  managers will typically have  portfolios of long equities
and short  equities  in equal  amounts.  While  this  strategy  does  offer some
flexibility,  managers in this  strategy are expected to keep their net exposure
within  +/-20%.  Leverage  will be employed.  Short  positions  can be hedges or
profit centers.  While an overall fund can be market neutral,  managers may take
sector  exposure  (though  many  do  not).  This  strategy  should  show  little
correlation to equity markets, as returns are driven by stock picking, or in the
case of quantitatively driven strategies, factors.


                                                                              18

              Notes to Financial Statements (unaudited) (continued)

13. INVESTMENTS (CONCLUDED)

Portfolio Funds' Investment Strategies (concluded):

EQUITY VARIABLE BIAS

Equity  Variable Bias managers will typically  have  portfolios of long equities
and short equities. As per the strategy name, net exposure is variable,  ranging
from net long to net short to market neutral.  Security  selection may either be
fundamental or quantitative while net exposure can be either bottom up (security
specific)  or top down  (macro  driven).  Leverage is also  variable,  with some
managers  in this  strategy  using  little or no leverage  while  others may use
substantial  leverage;  typically,  leverage  will be lower than found in Equity
Market Neutral.  Short positions can be hedges or profit centers. While the bulk
of the portfolio should consist of equities,  indices, ETFS, options and futures
may also be used. This strategy's  correlation to equity markets will vary, with
returns are driven by stock picking as well as net positioning.

EVENT DRIVEN

Event Driven managers will typically employ strategies that involve investing in
companies  experiencing  significant  corporate changes.  Mispricings arise from
events  such as  spin-offs,  restructurings,  stub  trades,  or other  corporate
changes that the broad market does not fully comprehend and appropriately value.
This strategy also includes  activist  managers who take  controlling  stakes in
companies and force the "event" internally.

RELATIVE VALUE

Relative  Value  managers  typically seek  risk-adjusted  absolute  returns with
volatility  and  correlation  lower than the broad equity  markets by allocating
assets to Advisors that operate  primarily in the global  relative value sector.
Relative  value  strategies  seek to profit  from the  mispricing  of  financial
instruments,  capturing  spreads  between  related  securities that deviate from
their  fair value or  historical  norms.  Directional  and  market  exposure  is
generally  held to a  minimum  or  completely  hedged.  Strategies  that  may be
utilized in the relative  value sector  include  convertible  arbitrage,  equity
arbitrage and fixed-income arbitrage. Other strategies may be employed as well.

14. RECENT ACCOUNTING PRONOUNCEMENTS

On July 13, 2006, the Financial  Accounting  Standards  Board ("FASB")  released
FASB  Interpretation  No. 48 "Accounting  for Uncertainty in Income Taxes" ("FIN
48").  FIN 48  provides  guidance  for how  uncertain  tax  positions  should be
recognized,  measured,  presented and disclosed in the financial statements. FIN
48 requires the evaluation of tax positions taken or expected to be taken in the
course of  preparing  the  Fund's  tax  returns  to  determine  whether  the tax
positions are  "more-likely-than-not"  of being  sustained by the applicable tax

                 Old Mutual Absolute Return Master Fund, L.L.C.
              Notes to Financial Statements (unaudited) (concluded)

14. RECENT ACCOUNTING PRONOUNCEMENTS (CONCLUDED)

Adoption of FIN 48 is required for fiscal  years  beginning  after  December 15,
2006 and is to be applied to all open tax years as of the effective date.  Based
on its analysis,  management has determined  that the adoption of FIN 48 did not
have a  material  impact  to the  Fund's  financial  statements  upon  adoption.
However,  management's conclusions regarding FIN 48 may be subject to review and
adjustment  at a later date  based on factors  including,  but not  limited  to,
further implementation guidance expected from the FASB, and on-going analyses of
and changes to tax laws, regulations and interpretations thereof.

In September  2006, the Financial  Accounting  Standards  Board ("FASB")  issued
Statement  on  Financial  Accounting  Standards  ("SFAS")  No. 157,  "Fair Value
Measurements." This standard  establishes a single  authoritative  definition of
fair  value,  sets  out a  framework  for  measuring  fair  value  and  requires
additional  disclosures about fair value  measurements.  SFAS No. 157 applies to
fair value  measurements  already  required or permitted by existing  standards.
SFAS No. 157 is  effective  for  financial  statements  issued for fiscal  years
beginning after November 15, 2007 and interim periods within those fiscal years.
The  changes  to  current  generally  accepted  accounting  principles  from the
application  of this  Statement  relate to the  definition  of fair  value,  the
methods used to measure  fair value,  and the  expanded  disclosures  about fair
value measurements.  At this time,  management is evaluating the implications of
FAS 157 and its impact on the financial statements has not yet been determined.


                                                                              20
