Organization Excelsior Absolute Return Fund of Funds Master Fund, LLC (the "Company") was organized as a limited liability company under the laws of Delaware on June 17, 2003, and commenced operations on December 1, 2003. The Company is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as a non- diversified, closed-ended management investment company. The Company's investment objective is to provide attractive long-term, risk-adjusted absolute returns in a variety of capital market conditions. The Company pursues its investment objective by investing its assets primarily in private investment limited partnerships, limited liability companies, joint ventures and other similar investment vehicles (collectively, the "Investment Funds") that are managed by a select group of alternative investment managers ("Investment Managers") that utilize a broad range of alternative investment strategies. U.S. Trust Hedge Fund Management, Inc. serves as the investment adviser of the Company (the "Adviser"). On July 1, 2007, the Adviser became an indirect wholly-owned subsidiary of Bank of America Corporation ("Bank of America"). As a result, the Adviser is now controlled by Bank of America. Bank of America is a bank holding and a financial holding company which has its principal executive offices at 101 North Tryon Street, Charlotte, North Carolina 28255. Prior to July 1, 2007, the Adviser was a wholly-owned subsidiary of U.S. Trust Corporation ("U.S. Trust"), a registered financial holding company, which in turn, was a wholly-owned subsidiary of The Charles Schwab Corporation. On July 1, 2007, U.S. Trust and its subsidiaries, including the Adviser, were acquired by Bank of America (the "Sale"). The Adviser continued to serve as the investment adviser to the Company after the Sale pursuant to a new investment advisory agreement with the Company (the "New Advisory Agreement") that was approved at a special meeting of members of the Company held on March 15, 2007. The New Advisory Agreement is identical in all material respects to the previous investment advisory agreement except for the term and the date of effectiveness. The Adviser is responsible for developing, implementing and supervising the investment program and providing day-to-day management services. The Adviser has retained AIG Global Investment Corp. ("AIG Global"), an indirect wholly-owned subsidiary of American International Group, Inc., to serve as the investment manager of the Company. AIG Global is responsible for Investment Fund selection and determining the portion of the Company's assets to be allocated to each Investment Fund, subject to the general supervision of the Adviser. <Page> Excelsior Absolute Return Fund of Funds Master Fund, LLC Notes to Financial Statements (Unaudited) continued - -------------------------------------------------------------------------------- September 30, 2007 - -------------------------------------------------------------------------------- 1. Organization (continued) The Board has overall responsibility to manage and supervise the operations of the Company, including the exclusive authority to oversee and to establish policies regarding the management, conduct and operation of the Company's business. The Board is comprised of three managers who are not "interested persons" (the "Disinterested Managers") and one manager who is an "interested person," as defined by Section 2(a)(19) of the 1940 Act of the Company. The Company was established to hold substantially all of the assets of Excelsior Absolute Return Fund of Funds, LLC (the "Feeder Fund") and Excelsior Absolute Return Fund of Funds, Ltd. (the "Offshore Fund") as members of the Company ("Members"). As of September 30, 2007, the Feeder Fund and Offshore Fund ownership of the Company's Members' Equity - Net Assets were 88.05 % and 11.95%, respectively. Member subscriptions for interests in the Company ("Interests") by eligible investors may be accepted as of the first day of each calendar quarter, or at such times as the Board may determine. The Company may, from time to time, offer to repurchase Interests from Members pursuant to written tenders by Members. These repurchase offers will be made at such times and on such terms as may be determined by the Board, in its sole discretion, subject to the liquidity of the Company's assets and other factors considered by the Board.The Adviser expects that, generally, it will recommend to the Board that the Company offer to repurchase Interests from Members twice each year, at June 30th and December 31st. Members can only transfer or assign Company Interests under certain limited circumstances. 2. Significant Accounting Policies The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Management believes that the estimates utilized in preparing the Company's financial statements are reasonable and prudent; however, actual results could differ from these estimates. a. Portfolio Valuation The net asset value of the Company is determined by, or at the direction of, the Adviser as of the close of business at the end of each fiscal period (as defined in the Company's Limited Liability Company Agreement), in accordance with the valuation principles set forth below, or as may be determined from time to time pursuant to policies established by the Board. <Page> Excelsior Absolute Return Fund of Funds Master Fund, LLC Notes to Financial Statements (Unaudited) continued - -------------------------------------------------------------------------------- September 30, 2007 - -------------------------------------------------------------------------------- 2. Significant Accounting Policies (continued) a. Portfolio Valuation (continued) Ordinarily, the Company's investments in Investment Funds are carried at fair value as determined by the Company's pro-rata interest in the net assets of each Investment Fund as reported by the Investment Manager who determines the value of the Investment Fund's net assets. The values of the Investment Funds' net assets are determined in accordance with their valuation policies as described in their respective offering memoranda or operating agreements. All valuations utilize financial information supplied by the Investment Manager of each Investment Fund and are net of management and performance incentive fees or allocations pursuant to the Investment Funds' agreements. As a general matter, the fair value of the Company's interest in an Investment Fund will represent the amount that the Adviser could reasonably expect to receive from the Investment Fund if the Company's interest were redeemed at the time of valuation, based on information reasonably available at the time the valuation is made and that the Adviser believes to be reliable. The Adviser or, in certain cases, the Board, will consider such information, and may conclude in certain circumstances that the information provided by an Investment Fund's manager does not represent the fair value of the Company's interests in an Investment Fund. Following procedures adopted by the Board, and in the absence of specific transaction activity in interests in a particular Investment Fund, the Company could consider whether it was appropriate, in light of all relevant circumstances, to value such a position at the Investment 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. Because of the inherent uncertainty of valuation, the values of the Company's investments may differ significantly from the values that would have been used had a ready market for the investments held by the Company been available. Distributions received from Investment Funds, whether in the form of cash or securities, are applied first as a reduction of the investment's cost, and any excess is treated as realized gain from investments in investment fund. Realized gains or losses on investments in Investment Funds are measured by the difference between the proceeds from the sale or liquidation and the cost basis of the investment using the specific identification method without regard to unrealized appreciation or depreciation reported in prior years. <Page> Excelsior Absolute Return Fund of Funds Master Fund, LLC Notes to Financial Statements (Unaudited) continued - -------------------------------------------------------------------------------- September 30, 2007 - -------------------------------------------------------------------------------- 2. Significant Accounting Policies (continued) b. Company Expenses The Company bears certain expenses incurred in its business, including, but not limited to, the following: fees paid directly or indirectly to the Investment Managers of the Investment Funds, all costs and expenses directly related to portfolio transactions and positions for the Company's account; legal fees; accounting and auditing fees; custodial fees; fees paid to the Company's administrator; costs of insurance; advisory fees; travel and related expenses of the Board; all costs with respect to communications regarding the Company's transactions among the Adviser and any custodian or other agent engaged by the Company; and other types of expenses approved by the Board. c. Income Taxes As a limited liability company, no provision for the payment of Federal, state or local income taxes has been provided by the Company. Each Member is individually required to report on its own tax return its share of the Company's taxable income or loss. The Company has a tax year end of December 31. Net investment income or loss and net realized and unrealized gain or loss from investments of the Company for each fiscal period are allocated among, and credited to or debited against, the capital accounts of all Members as of the last day of each fiscal period in accordance with each Member's respective investment percentage for the fiscal period, as defined in the Company's Limited Liability Company Agreement. The cost of the Company's investment in Investment Funds for Federal income tax purposes is based on amounts reported to the Company by the Investment Funds on a Schedule K-1 or PFIC annual information statement for the year ended December 31, 2006. Based on Investment Funds owned at December 31, 2006, the cost of investments for Federal income tax purposes was $236,284,953. This included aggregate gross unrealized appreciation of $17,681,157 and aggregate gross unrealized depreciation of $2,965,391. d. New Accounting Pronouncements In July 2006, the Financial Accounting Standards Board ("FASB") issued Interpretation 48, Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement 109 ("FIN 48"). FIN 48 clarifies the accounting for income taxes by prescribing the minimum recognition threshold a tax position must meet before being recognized in the financial statements. FIN 48 is effective for fiscal years beginning after December 15, 2006. The Company is in the process of evaluating the effects of the adoption of FIN 48 on the financial statements. <Page> Excelsior Absolute Return Fund of Funds Master Fund, LLC Notes to Financial Statements (Unaudited) continued - -------------------------------------------------------------------------------- September 30, 2007 - -------------------------------------------------------------------------------- 2. Significant Accounting Policies (continued) d. New Accounting Pronouncements (continued) FASB issued a Statement No. 157 in September 2006, Fair Value Measurements, which is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. This statement provides enhanced guidance for using fair value to measure assets and liabilities. It clarifies fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. The standard applies whenever other standards require (or permit) assets or liabilities to be measured at fair value. The standard does not expand the use of fair value in any new circumstances.

Financial Instruments with Off-Balance Sheet Risk In the normal course of business, the Investment Funds in which the Company invests, trade various financial instruments and enter into various investment activities with off-balance sheet risk. These may include, but are not limited to, short selling activities, writing option contracts, contracts for differences and equity swaps. However, as a result of the investments by the Company as a limited partner or member, the Company's liability with respect to its investments in the Investment Funds is limited to the net asset value of its interest in each Investment Fund. 5. Investments in Investment Funds As of September 30, 2007, the Company had investments in twenty-nine Investment Funds. The agreements related to investments in Investment Funds provide for compensation to the general partners/managers of the Investment Funds in the form of management fees of 1.0% to 2.0% (per annum) of net assets and incentive fees or allocations ranging from 20% to 25% of net profits earned. The Investment Funds provide for periodic redemptions, with lock-up provisions ranging from one month to one year from initial investment.

Bank Note- Line of Credit Facility The Company maintains a $25,000,000 revolving line of credit agreement with a U.S. financial institution that is collateralized by the Company's cash and investments. Based upon the election of the Company, interest accrues at either the financial institution's prime rate less 1.25% per annum or Libor plus 1.5% per annum.

Guarantees In the normal course of business, the Company enters into contracts that provide general indemnifications. The Company's maximum exposure under these arrangements is dependent on future claims that may be made against the Company, and therefore, cannot be established; however, based on experience, the risk of loss from such claim is considered remote. <Page> Excelsior Absolute Return Fund of Funds Master Fund, LLC Notes to Financial Statements (Unaudited) continued - -------------------------------------------------------------------------------- September 30, 2007 - -------------------------------------------------------------------------------- 8.
