REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Managers and Members of
Old Mutual Absolute Return Master Fund, L.L.C.

We have audited the accompanying statement of assets and liabilities of Old Mutual Absolute Return Master Fund, L.L.C. (the “Master Fund”), including the schedule of investments, as of March 31, 2011, and the related statements of operations and cash flows for the year then ended, the statements of changes in members’ capital for each of the two years in the period then ended and financial highlights for each of the three years in the period then ended. These financial statements and financial highlights are the responsibility of the Master Fund’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audit. The financial highlights for the period November 1, 2006 (commencement of operations) through March 31, 2007 and for the year ended March 31, 2008 were audited by an independent registered public accounting firm whose report dated May 29, 2008 expressed an unqualified opinion on those financial highlights.

We conducted our audits 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 and financial highlights are free of material misstatement. The Master Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Master Fund’s internal control over financial reporting. Accordingly, we express no such opinion. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of investments owned as of March 31, 2011, by correspondence with the custodian and portfolio funds. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Old Mutual Absolute Return Master Fund, L.L.C. as of March 31, 2011, the results of its operations and its cash flows for the year then ended, the changes in its members’ capital for each of the two years in the period then ended, and the financial highlights for each of the three years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

Old Mutual Absolute Return Master Fund, L.L.C.
Notes to Financial Statements
March 31, 2011

1. Organization

Old Mutual Absolute Return Master Fund, L.L.C. (the “Fund”) is a Delaware limited liability company that is registered under the Investment Company Act of 1940, as amended (the “1940 Act”) with the United States Securities and Exchange Commission (“SEC”), 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”) and Old Mutual Absolute Return Institutional Fund, L.L.C. (the “Institutional Feeder Fund”), (collectively, the “Feeders” or “Members”), invest substantially all of their assets. As of March 31, 2011, the Feeder Fund’s investment in the Fund represented 89.8% of Members’ Capital and the Institutional Feeder Fund’s investment in the Fund represented 10.2% 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.

In December 2010, the Board of Managers of the Fund approved the merger of Old Mutual Emerging Managers Master Fund, L.L.C. (“EMMF”) into the Fund. The reorganization occurred as of March 31, 2011, at which time members of EMMF were issued their pro-rata share of interests of the Fund. See Note 9 for further details.

2. Summary of Significant Accounting Policies

Basis of Presentation

The Fund’s financial statements are prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and the rules and regulations of the SEC. The following is a summary of the significant accounting policies followed by the Fund:

9

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

2. Summary of Significant Accounting Policies (continued)

A. Use of Estimates

The preparation of financial statements in conformity with GAAP 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.

B. Valuation of Portfolio Investments at Fair Value and Investment Transactions

GAAP establishes a fair value hierarchy and specifies that a valuation technique used to measure fair value shall maximize the use of observable inputs and minimize the use of unobservable inputs. The objective of a fair value measurement is to determine the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (an exit price). Accordingly, the fair value hierarchy gives the highest priority to quoted prices (unadjusted) in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3).

The three levels of the fair value hierarchy under GAAP are described below:

• Level 1 — Unadjusted quoted prices in active markets for identical, unrestricted assets or liabilities that the Fund has the ability to access at the measurement date;

• Level 2 — Quoted prices which are not active, or inputs that are observable (either directly or indirectly) for substantially the full term of the asset or liability; and

• Level 3 — Prices, inputs or exotic modeling techniques which are both significant to the fair value measurement and unobservable (supported by little or no market activity).

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 primarily based on the fair value of each of its interests in Portfolio Funds.

10

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

2. Summary of Significant Accounting Policies (continued)

As permitted under GAAP, the investments in portfolio funds are valued, as a practical expedient, utilizing the net asset valuations provided by the underlying portfolio funds, without adjustment, when the net asset valuations of the portfolio funds are calculated (or adjusted by the Fund if necessary) in a manner consistent with GAAP for investment companies. 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. In its determination of fair value the Board considers subscription and redemption rights, including any restrictions on the redemptions from the Portfolio Funds. Investments in portfolio funds are included in either Level 2 or 3 of the fair value hierarchy. In determining the level, the Fund considers the length of time until the investment is redeemable including notice and lock up periods or any other restriction on the disposition of the investment. The Fund also considers the nature of the portfolios of the portfolios of the underlying portfolio funds and their ability to liquidate their underlying investments. 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. Investment transactions 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 and cash equivalents.

As required by GAAP, investments are classified within the level of the lowest significant input considered in determining fair value. Investments classified within Level 3 consider several inputs and may include Level 1 or Level 2 inputs as components of the overall fair value measurement.

2. Summary of Significant Accounting Policies (continued)

The table below sets forth information about the level within the fair value hierarchy at which the Fund’s investments are measured at March 31, 2011:

	Level 1 —
	Quoted Prices		Level 2 —
	in Active		Significant		Level 3 —
	Markets for		Other		Significant
	Identical		Observable		Unobservable			Total as of
Assets (at fair value)	Assets		Inputs		Inputs			March 31, 2011
Investments in Portfolio Funds	$	—	$	31,438,721	$	415,936	*	$	31,854,657
Cash Equivalent		2,589,529		—		—			2,589,529
Total	$	2,589,529	$	31,438,721	$	415,936		$	34,444,186

* Level 3 investments consist of the following Portfolio Funds: Cedar Hill Onshore Mortgage Opportunity Fund, L.P, JANA Piranha Fund, L.P., GoldenTree Partners, L.P., Greywolf Capital Partners II, L.P., the side pocket portion equal to $25,030 of Jana Partners Qualified LP and Octavian Global Fund, LP and D.E. Shaw Composite Fund, LLC.

The following is a reconciliation of the investments in which significant unobservable inputs (Level 3) were used in determining value:

Beginning		Realized and											Ending
Balance as of		unrealized			Net purchase/			Transfer in					Balance as of
April 1, 2010		gains/(losses)			sales			from merger		Transfer in/out			March 31, 2011
$	1,441,454	$	(8,672	)	$	(800,275	)	$	202,546	$	(419,117	)	$	415,936

Realized and unrealized gains and losses are included in net gain (loss) on investments in the Statement of Operations. The change in unrealized gains (losses) for the year ended March 31, 2011 for investments still held at March 31, 2011 of $(29,863) is reflected in net change in unrealized appreciation/depreciation on investments in Portfolio Funds.

There were no transfers during the year ended March 31, 2011, between Level 1 and Level 2. For the year ended March 31, 2011, there have been no significant changes to the Fund’s fair value methodologies.

Of the Level 2 investments presented above, some equity investments were considered level 3 investments at the beginning of the year. The primary reasons for changes in the classifications between levels 2 and 3 are changes to the liquidity of the Fund’s Portfolio Investments or changes to underlying portfolio leveling of such Portfolio Investments. The dollar amounts of such transfers are disclosed in the table above.

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.

The Fund evaluates tax positions taken or expected to be taken in the course of preparing the Fund’s tax returns to determine whether it is “more-likely than-not” (i.e., greater than 50-percent) that each tax position will be sustained upon examination by a taxing authority based on the technical merits of the position. Tax positions not deemed to meet the more-likely-than-not threshold are recorded as a tax benefit or expense in the current year. The Fund did not record any tax provision in the current period. However, management’s conclusions regarding tax positions taken may be subject to review and adjustment at a later date based on factors including, but not limited to, examination by tax authorities (i.e., the last 3 tax year ends, as applicable), on-going analysis of and changes to tax laws, regulations and interpretations thereof. Management of the Fund does not expect that its assessment regarding unrecognized tax benefits will materially change over the next twelve months.

As of and during the year ended March 31, 2011, the Fund did not have a liability for any unrecognized tax benefits. The Fund recognizes interest and penalties, if any, related to unrecognized tax benefits as income tax expense in the Statement of Operations. During the year ended March 31, 2011, the Fund did not incur any significant interest or penalties.

The Fund files an income tax return in the U.S. federal jurisdiction, U.S. states or foreign jurisdiction authorities in the areas of income taxes. These potential examinations may include questioning and the timing and amount of deductions, the nexus of income among various tax jurisdictions and compliance with U.S. federal, U.S. state and foreign tax laws.

The aggregate income tax basis of investments was approximately $29,705,000. Net unrealized appreciation on investments for income tax purposes was approximately $2,150,000, consisting of $2,616,000 of gross unrealized appreciation and $(466,000) of gross unrealized depreciation.

D. 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.

E. Cash Equivalent

As of March 31, 2011, cash equivalent consists of an investment in a money market fund affiliated with the Administrator (as defined in Note 3).

F. Accounting Pronouncements Recently Issued or Adopted

In May 2011, the “FASB” issued ASU 2011-04, Fair Value Measurement and Disclosure (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS. The amendments in this Update explain how to measure fair value and consequently, the amendments change the wording used to describe many of the requirements in U.S. GAAP for measuring fair value and for disclosing information about fair value measurements. They do not require additional fair value measurements and are not intended to establish valuation standards or affect valuation practices outside of financial reporting. The amendments include requirements specific to measuring the fair value of those instruments, such as equity interests issued as consideration in a business combination. Those amendments are consistent with the requirements for measuring the fair value of liabilities and specify that a reporting entity should measure the fair value of its own equity instrument from the perspective of a market participant that holds that instrument as an asset. The amendments in this Update clarify that the application of premiums and discounts in a fair value measurement is related to the unit of account for the asset or liability being measured at fair value. The amendments expand the disclosures about fair value measurements categorized within Level 3 of the fair value hierarchy: (1) The valuation processes used by the reporting entity (2) The sensitivity of the fair value measurement to changes in unobservable inputs and the interrelationships between those unobservable inputs, if any. The amendments are effective during interim and annual periods beginning after December 15, 2011. Early application by public entities is not permitted. At this time the Fund is evaluating the implications of the amendments to ASC 820 and the impact on the financial statements.

3. Related Party Transactions and Other

A. Related Party Transactions

Larch Lane Advisors LLC (the “Adviser”), a Delaware limited liability company, serves as the investment adviser of the Fund. The Adviser is a registered investment adviser (RIA) under the Investment Advisers Act of 1940, as amended (the “Advisers Act”). LLA Holdings, LLC, the special member of the Adviser, owns a majority 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. The Adviser is responsible for developing, implementing and supervising the Fund’s investment program and providing day-to-day management services to the Institutional Feeder Fund. The Adviser has also paid various expenses for the Fund for which the Fund has a non-interest bearing payable which is due upon demand. The accompanying Statement of Assets and Liabilities includes a payable to Adviser of $5,707.

14

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

3. Related Party Transactions and Other (concluded)

Under the agreement with the Adviser, the Fund does not pay any investment management fee to the Adviser. The fees are paid at the Feeder Fund level. 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.

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 agreements, 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.

B. Other

Pursuant to an administrative services agreement, 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.

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. 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.

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.

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 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 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. Amounts shown as expenses in the Statement of Operations and Financial Highlights include only those expenses charged directly to the Fund and do not reflect management fees, advisory fees, brokerage commissions and other fees and expenses incurred by the Portfolio Funds in which the Fund invested. These amounts are included in realized and unrealized gain (loss) on investments in funds in the Statement of Operations.

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. 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 year ended March 31, 2011.

16

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

6. 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.

7. 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. 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.

8. 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 the Fund’s Investment.

17

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

9. Reorganization

On March 31, 2011, EMMF was reorganized into the Fund. Capital of $15,704,170, which was comprised of investments, cash, receivables and other assets and liabilities, was provided to the Fund in exchange for members’ interests in the Fund. The investments were transferred in at fair value and therefore there was no unrealized appreciation or depreciation on these investments at March 31, 2011. EMMF and the Fund are both managed by the Adviser.

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. Risk and Uncertainties

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.

Notes to Financial Statements (continued)

11. Risk and Uncertainties (continued)

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) 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 a 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.

19

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

11. Risk and Uncertainties (continued)

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.

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.

20

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

11. Risk and Uncertainties (continued)

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 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.

21

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

11. Risk and Uncertainties (continued)

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. Further, from time to time, certain Portfolio Managers may allocate certain Portfolio Fund assets (which generally are illiquid) to special investment accounts within the particular Portfolio Fund managed by the Portfolio Manager (i.e., “side pockets” or “special investment accounts”). Generally, the Portfolio Funds will not be able to withdraw their interest in such side pockets or special investment accounts until they are disposed of by the Portfolio Manager. The market prices, if any, for illiquid securities tend to be volatile and a Portfolio Fund may not be able to sell them when it desires to do so or to realize what it perceives to be their fair value in the event of a sale. 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 up to two years from the initial investment. The liquidity provisions shown on the Schedule of Investments apply after the lock-up provisions expire.

Certain Portfolio Funds may restrict the ability of investors to redeem their interests in the fund, whether temporarily or during a liquidation of the Portfolio Fund, and may seek to amend their liquidity provisions and impose additional restrictions on investor liquidity. Certain Portfolio Funds may permit withdrawals on a date other than as provided under standard liquidity terms subject to the payment of certain additional fees or charges.

M. Credit Risk

The Fund will be exposed to credit risk on Portfolio Funds with whom they trade and will always bear the risk of settlement on default.

Notes to Financial Statements (continued)

11. Risk and Uncertainties (continued)

N. Interest Rate Risk

A number of the underlying funds that the Fund invests in may be interest rate sensitive, which means that their value and consequently, the Net Asset Value of the Fund, may fluctuate as interest rates fluctuate.

12. Investment Transactions

For the year ended March 31, 2011, the Fund made investments in Portfolio Funds in the amount of $8,195,095 and redeemed investments in Portfolio Funds in the amount of 8,475,801.

13. Investments

As of March 31, 2011, the Fund had investments in thirty-six Portfolio Funds, none of which are 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 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:

Directional

Directional strategies derive their primary source of return from directional positions in asset classes. These strategies include global macro funds and commodity trading advisors (“CTA”). Macro strategies generally utilize analysis of macro-economic, geopolitical and financial conditions to establish directional views and seek to capitalize on such views by trading in securities, commodities, interest rates, currencies and other instruments. CTA strategies also look to establish directional views on various financial instruments and geographies but generally do so in a systematic manner.

Equity Strategies

Equity Strategies derive their primary source of return from positions in the equity markets. Stock selection is of primary importance to these strategies. Equity strategies include long-bias, short-bias, variable bias and equity market neutral strategies. Long bias managers will always be net long, short bias managers are expected to maintain a negative net exposure; variable bias managers can adjust net exposure and be either net long, net short or market neutral; equity market neutral managers are expected to maintain a net exposure +/-20%.

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.

Opportunistic

Opportunistic strategies derive their primary source of return from a broad range of strategies, asset classes and securities, investing opportunistically across the broad spectrum of asset classes. They seek to invest in strategies, asset classes and geographies that they feel exhibit the best risk/reward profile. These managers are expected to dynamically adjust their exposure and positions as market opportunities vary.

24

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

13. Investments (continued)

Protection Strategies

Protection Strategies are designed to provide a positive rate of return during times of market stress. These strategies often take the form of being short traditional asset classes, such as equities or fixed income. These strategies could also feature a long volatility component or other positions designed to profit during market declines. Protection Strategies are not expected to be profitable during positive markets.

14. Subsequent Events

Effective April 1, 2011, the Fund made investments in Portfolio Funds in the amount of $2,900,000 (of which $1,900,000 is included in Fund investments made in advance in the statement of Assets and Liabilities).

Effective April 1, 2011 the Fund changed its name to Larch Lane Multi Strategy Master Fund, L.L.C.

In May 2011, the Fund received $500,000 from two of its underlying investments which were sold at April 30, 2011.

On May 26, 2011, the Board determined, consistent with the best interests of the Fund and its Members, to authorize the Fund’s officers to pursue a liquidation of the Fund. As a result of this authorization, the Fund has: (i) ceased offering, and is not accepting any purchases of Units, (ii) terminated and withdrew the offer to repurchase Units that had commenced on April 6, 2011 and (iii) ceased to make any further offers to repurchase Units. Members will receive a further notification of the Fund’s expected liquidation schedule.

Item 6. Schedule of Investments

Item 7. Disclosure of Proxy Voting Policies and Procedures for Closed-End Management Investment Companies.

The following is the Proxy Voting Policies and Procedures of Larch Lane Advisors LLC (the “Adviser”) in its entirety:

The Firm provides investment advisory services to private investment funds and managed accounts, and invests the assets of these Funds and accounts in securities issued by private issuers. Through these private issuers the Firm may be delegated the right to vote, on behalf of the Funds and accounts, proxies received from companies, the securities of which are owned by the underlying private issuers in which the Funds and accounts have invested. In addition, from time to time, the private issuers may amend or revise their governing documents or seek investor consents. The Firm has authority to vote proxies relating to such securities on behalf of the Funds and accounts it manages.

The Securities and Exchange Commission (the “SEC”) has adopted Rule 206(4)-6 under the Investment Advisers Act. Under this rule, registered investment advisers that exercise voting authority over securities held in client portfolios are required to implement proxy voting policies and describe those policies to their clients.

The Investment Committee (which may delegate a Proxy Committee for this purpose) is responsible for making all proxy voting decisions in accordance with these proxy voting policy and procedures (the “Policies”). The investment team is responsible for the actual voting of all proxies in a timely manner, while the Compliance Officer is responsible for monitoring the effectiveness of the Policies. (See Section IV, “Procedures for Proxies”.)

The Policies attempt to generalize a complex subject. The Firm may, from time to time, determine that it is in the best interests of its clients to depart from specific policies described herein. The rationale for any such departure will be memorialized in writing by the Compliance Officer.

I. General Policy

The general policy is to vote proxy proposals, amendments, consents or resolutions relating to client securities, including interests in private investment funds, if any (collectively, “proxies”), in a manner that reasonably furthers the best interests of the Funds managed by the Firm and is consistent with the investment philosophy as set forth in the relevant investment management documents, as determined by the Firm in its discretion, and taking into account relevant factors, including, but not limited to:

• the impact on the value of the securities;

• the anticipated costs and benefits associated with the proposal;

• the effect on liquidity; and

• customary industry and business practices.

II. Specific Policies

A. Routine Matters

Routine matters are typically proposed by Management (as defined below) of a company and meet the following criteria: (i) they do not measurably change the structure, management, control or operation of the company; (ii) they do not measurably change the terms of, or fees or expenses associated with, an investment in the company; and (iii) they are consistent with customary industry standards and practices, as well as the laws of the state of incorporation applicable to the company.

For routine matters, the Firm will vote in accordance with the recommendation of the company’s management, directors, general partners, managing members or trustees (collectively, the “Management”), as applicable, unless, in the Firm’s opinion, such recommendation is not in the best interests of the investing Funds or accounts.

1. General Matters

The Firm will generally vote for proposals:

          • to set time and location of annual meeting;

          • to change the fiscal year of the company; and

          • to change the name of a company.

2. Board Members

a. Election or Re-Election. The Firm will generally vote for Management proposals to elect or re-elect Board members.

b. Fees to Board Members. The Firm will generally vote for proposals to increase fees paid to Board members, unless it determines that the compensation exceeds market standards.

3. Capital Structure

The Firm will generally vote for proposals to change capitalization, including to increase authorized common shares or to increase authorized preferred shares, as long as the proposal does not either: (i) establish a class or classes of shares or interests with terms that may disadvantage the class held by the investing Funds or accounts or (ii) result in disproportionate voting rights for preferred shares or other classes of shares or interests.

4. Appointment of Auditors

The Firm will generally vote for the approval of auditors and proposals authorizing the Board to fix auditor fees, unless:

          • the Firm has serious concerns about the accountants presented, including their independence, or the audit procedures used; or

          • the auditors are being changed without explanation.

B. Non-Routine Matters

Non-routine matters involve a variety of issues and may be proposed by a company’s Management or beneficial owners (i.e., shareholders, members, partners, etc. (collectively, the “Owners”)). These proxies may involve one or more of the following: (i) a measurable change in the structure, management, control or operation of the company; (ii) a measurable change in the terms of, or fees or expenses associated with, an investment in the company; or (iii) a change that is inconsistent with industry standards and/or the laws of the state of incorporation applicable to the company.

1. Board Members

a. Term Limits. The Firm will generally vote for proposals to require a reasonable retirement age (e.g., 72) for Board members, and will vote on a case-by-case basis on proposals to attempt to limit tenure.

b. Replacement. The Firm will generally vote against proposals that make it more difficult to replace Board members, including proposals:

          • to stagger the Board;

          • to overweight Management representation on the Board;

          • to introduce cumulative voting (cumulative voting allows the Owners to “stack” votes behind one or a few individuals for a position on the Board, thereby giving minority Owners a greater chance of electing the Board member(s));

          • to introduce unequal voting rights;

          • to create supermajority voting; or

          • to establish pre-emptive rights.

c. Liability and Indemnification. In order to promote accountability, the Firm will generally vote against proposals to limit the personal liability of Board members for any breach of fiduciary duty or failure to act in good faith.

d. Ownership Issues. The Firm will generally vote for proposals that require Management to own a minimum interest in the company. The purpose of this policy is to encourage the alignment of Management’s interests with the interests of the company’s Owners. However, the Firm will generally vote against proposals for stock options or other compensation that grant an ownership interest for Management if such proposals offer greater than 15% of the outstanding securities of a company because such options may dilute the voting rights of other Owners of the company.

2. Compensation, Fees and Expenses

In general, the Firm will vote against proposals to increase compensation, fees or expenses to be paid to the company’s Owners, unless the Firm determines that the benefits resulting to the company and its Owners justifies the increased compensation, fees or expenses.

In many circumstances, where private investment funds seek to change material terms such as compensation, fee and expense terms, the Firm will examine the investment opportunity anew in light of the proposed new terms, considering the private investment funds returns, portfolio and strategy allocations, alternative investment opportunities and other factors generally considered when making an investment decision. When applying this examination, the Firm may vote for proposals where the circumstances of a particular investment justify the revised compensation, fee and expense terms.

3. Voting Rights

The Firm will generally vote against proposals:

          • to introduce unequal voting or dividend rights among the classes;

          • to change the amendment provisions of a company’s charter documents by removing Owner approval requirements;

          • to require supermajority (²/ ₃) approval for votes rather than a simple majority (¹/2);

          • to restrict the Owners’ right to act by written consent; or

          • to restrict the Owners’ right to call meetings, propose amendments to the articles of incorporation or other governing documents of the company or nominate Board members.

The Firm will generally vote for proposals that eliminate any of the foregoing rights or requirements.

4. Takeover Defenses and Related Actions

The Firm will generally vote against any proposal to create any plan or procedure designed primarily to discourage a takeover or other similar action, including “poison pills”. Examples of “poison pills” include:

          • large increases in the amount of stock authorized but not issued;

          • blank check preferred stock (stock with a fixed dividend and a preferential claim on company assets relative to common shares, the terms of which are set by the Board at a future date without further action by the Owners);

          • compensation that would act to reward Management as a result of a takeover attempt, whether successful or not, such as revaluing purchase price of stock options, or “golden parachutes”;

          • fixed price amendments that require a certain price to be offered to all Owners based on a fixed formula; and

          • greenmail provisions that allow a company to make payments to a bidder in order to persuade the bidder to abandon its takeover plans.

The Firm will generally vote for proposals that eliminate any of the foregoing rights or requirements, as well as proposals to:

          • require that golden parachutes or golden handcuffs be submitted for ratification by the Owners; and

          • to opt out of state anti-takeover laws deemed by the Firm to be detrimental.

The Firm will generally vote on a case-by-case basis regarding other proposals that may be used to prevent takeovers, such as the establishment of employee stock purchase or ownership plans.

5. Reincorporation

The Firm will generally vote for a change in the state of incorporation if the change is for valid business reasons (such as reincorporating in the same state as the headquarters of any controlling company).

6. Debt Issuance and Pledging of Assets for Debt

The Firm will generally vote proxies relating to the issuance of debt, the pledging of assets for debt, and an increase in borrowing powers on a case-by-case basis, taking into consideration relevant factors, including, for example:

          • the potential increase in the company’s outstanding interests or shares, if any (e.g., convertible bonds); and

          • the potential increase in the company’s capital, if any, over the current outstanding capital.

7. Mergers or Acquisitions

The Firm will vote proxies relating to mergers or acquisitions on a case-by-case basis, but will generally vote for any proposals that the Firm believes will offer fair value to its clients.

8. Termination or Liquidation of the Company

The Firm will vote proxies relating to the termination or liquidation of a company on a case-by-case basis, taking into consideration one or more of the following factors:

          • terms of liquidation;

          • past performance of the company; and

          • strategies employed to save the company.

9. Social & Environmental Issues and Corporate Responsibility

The Firm will vote proxies relating to social and environmental issues on a case-by-case basis, but will generally vote for any proposals that will reduce discrimination, improve protections to minorities and disadvantaged classes, and increase conservation of resources and wildlife.

The Firm will generally vote against any proposals that place arbitrary restrictions on the company’s ability to invest, market, enter into contractual arrangements or conduct other activities. The Firm will also generally vote against proposals:

          • to bar or restrict charitable contributions; or

          • to limit corporate political activities.

10. All Other Matters

All other decisions regarding proxies will be determined on a case-by-case basis taking into account the general policy, as set forth above.

C. Abstaining from Voting or Affirmatively Not Voting

The Firm will abstain from voting (which generally requires submission of a proxy voting card) or affirmatively decide not to vote if the Firm determines that abstaining or not voting is in the best interests of the Fund or account. In making such a determination, the Firm will consider various factors, including, but not limited to: (i) the costs associated with exercising the proxy (e.g., translation or travel costs); and (ii) any legal restrictions on trading resulting from the exercise of a proxy. The Firm will not abstain from voting or affirmatively decide not to vote a proxy if the Fund or account is a plan asset fund subject to the requirements of the Employee Retirement Income Security Act of 1974, as amended. Furthermore, the Firm will not abstain from voting or affirmatively decide not to vote merely to avoid a conflict of interest.

III. Conflicts of Interest

At times, conflicts may arise between the interests of the investing Funds or accounts, on the one hand, and the interests of the Firm or its affiliates, on the other hand. If the Firm determines that it has, or may be perceived to have, a conflict of interest when voting a proxy, the Firm will address matters involving such conflicts of interest as follows:

A. If a proposal is addressed by the specific policies herein, the Firm will vote in accordance with such policies;

B. If the Firm believes it is in the best interest of the investing Funds or accounts to depart from the specific policies provided for herein, the Firm will be subject to the requirements of C or D below, as applicable;

C. If the proxy proposal is (1) not addressed by the specific policies or (2) requires a case-by-case determination by the Firm, the Firm may vote such proxy as it determines to be in the best interest of the investing Funds or accounts, without taking any action described in D below, provided that such vote would be against the Firm’s own interest in the matter (i.e., against the perceived or actual conflict). The Firm will memorialize the rationale of such vote in writing; and

D. If the proxy proposal is (1) not addressed by the specific policies or (2) requires a case-by-case determination by the Firm, and the Firm believes it should vote in a way that may also benefit, or be perceived to benefit, its own interest, then the Firm must take one of the following actions in voting such proxy: (a) delegate the voting decision for such proxy proposal to an independent third party; (b) delegate the voting decision to an independent committee of partners, members, directors or other representatives of the Funds or accounts, as applicable; (c) inform the investors in the investing Funds or the owners of the investing accounts of the conflict of interest and obtain consent to (majority consent in the case of a Fund) vote the proxy as recommended by the Firm; or (d) obtain approval of the decision from the Firm’s Compliance Officer and third party Legal Advisors.

IV. Procedures for Proxies

The Investment Committee will be responsible for determining whether each proxy is for a “routine” matter or not, as described above. All proxies identified as “routine” will be voted by the Chief Legal Officer in accordance with the Policies.

Any proxies that are not clearly “routine” will be submitted to the Investment Committee, who/which will determine how to vote each such proxy by applying the Policies. Upon making a decision, the proxy will be executed and returned to the Chief Legal Officer for submission to the company. Upon receipt of an executed proxy, the Firm’s paralegal will update the investing Funds’ or accounts’ proxy voting record. The Chief Legal Officer is responsible for the actual voting of all proxies in a timely manner. The Compliance Officer is responsible for monitoring the effectiveness of the Policies.

In the event the Firm determines that the investing Funds or accounts should rely on the advice of an independent third party or a committee regarding the voting of a proxy, the Firm will submit the proxy to such third party or committee for a decision. The Chief Legal Officer will execute the proxy in accordance with such third party’s or committee’s decision.

V. Record of Proxy Voting

The Compliance Officer also will maintain, or have available, written or electronic copies of each proxy statement received and of each executed proxy.

The Compliance Officer will also maintain records relating to each proxy, including (i) the determination as to whether the proxy was routine or not, (ii) the voting decision with regard to each proxy; and (iii) any documents created by the Investment Committee, or others, that were material to making the voting decision.

The Firm will maintain a record of each written request from an investor in a Fund or owner of an managed account for proxy voting information and the Firm’s written response to any request (oral or written) from an investor in a Fund or owner of an managed account for proxy voting information.

The Compliance Officer will maintain such records in its offices for two years from the end of the fiscal year during which the record was created, and for an additional three years in an easily accessible place.

Item 8. Portfolio Managers of Closed-End Management Investment Companies

(a)(1) Portfolio Managers

     The day-to-day management of the Fund’s and the Master Fund’s portfolio will be the responsibility of the Adviser’s Investment Committee, which is led by Mark Jurish, the Adviser’s Chief Investment Officer, and also includes Kenneth Stemme and Kevin Mirabile.

Mark Jurish, Chief Investment Officer, founded Larch Lane Advisors L.P., the predecessor entity of the Adviser, in August 1999.

From 1999 to 2002, Mr. Stemme was Executive Director in the Alternative Investment Group at CIBC Oppenheimer, where he was involved in the creation and management of a registered fund of funds. From 1990 through 1998, Mr. Stemme worked at Harris Associates, last serving as a research associate. Mr. Stemme received his B.A. from Cornell University and his M.B.A. from DePaul University.

Mr. Stemme is a member of the Investment Committee.

Kevin Mirabile, Chief Operating Officer, joined the Adviser in May 2008. Immediately prior to joining Larch Lane, Mr. Mirabile was C.O.O. of Orca Asset Management, a registered investment adviser. Mr. Mirabile has over 20 years of business development, regulatory, financing, trading and sales experience with the hedge fund sector dating back to 1983. Mr. Mirabile was previously a principal at Morgan Stanley, President of the Morgan Stanley Trust Company, an Executive V.P. at Daiwa Securities and a Managing Director and Operating Committee Member of Barclays Capital.

Mr. Mirabile is a member of the Investment Committee.

(a)(2) Other Funds and Accounts Managed

     The following table sets forth information about funds and accounts, other than the Fund, for which the Portfolio Managers are primarily responsible for the day-to-day portfolio management as of March 31, 2011.

Investment decisions at the Adviser are made with oversight by the Investment Committee. The committee holds regular meetings to discuss the investment portfolios, and their exposure in terms of risk and strategy, and to review forthcoming investment decisions.

Real, potential or apparent conflicts of interest may arise when a Portfolio Manager has day-to-day portfolio management responsibilities with respect to more than one fund. The Portfolio Managers may manage other accounts with investment strategies similar to the Fund and the Master Fund, including other investment companies, pooled investment vehicles and separately managed accounts. Fees earned by the Adviser may vary among these accounts and the Portfolio Managers may personally invest in these accounts. These factors could create conflicts of interest because Portfolio Managers may have incentives to favor certain accounts over others, resulting in other accounts outperforming the Fund or the Master Fund. A conflict may also exist if the Portfolio Managers identify a limited investment opportunity that may be appropriate for more than one account, but the Fund or the Master Fund is not able to take full advantage of that opportunity due to the need to allocate that opportunity among multiple accounts. In addition, the Portfolio Managers may execute transactions for another account that may adversely impact the value of securities held by the Fund or the Master Fund. However, the Adviser believes that these risks are mitigated by the fact that accounts with like investment strategies managed by the Portfolio Managers are generally managed in a similar fashion and the Adviser has a policy that seeks to allocate opportunities on a fair and equitable basis.

(a)(3) Compensation

As of March 31, 2011, compensation for the Portfolio Managers is a combination of a fixed salary and a bonus. The bonus paid to a Portfolio Manager for any year may be made with reference, in part, to the performance of the Fund or the Master Fund or any other fund or account managed by the Adviser during such year as compared to the performance of the HFR Fund of Funds Composite Index or another index or indices deemed relevant by the senior management of the Adviser. The amount of salary and bonus paid to the Portfolio Managers is based on a variety of factors, including the financial performance of the Adviser, execution of managerial responsibilities, client interactions and teamwork support. As part of their compensation, the Portfolio Managers also have 401k plans that enable them to direct a percentage of their pre-tax salary and bonus, without any contribution from the Adviser, into a tax-qualified retirement plan.

(a)(4) Fund Ownership

The following table sets forth the dollar range of Units beneficially owned by the Portfolio Managers as of the date of this Prospectus.

Portfolio Manager	Dollar Range
Mark Jurish	None
Kenneth Stemme	None
Kevin Mirabile	None
