REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


To the Members and Board of Managers of
Excelsior Absolute Return Fund of Funds Master Fund, LLC

We have audited the accompanying statements of asset, liabilities and members'
equity - net assets of Excelsior Absolute Return Fund of Funds Master fund, LLC
(the "Company"), including the schedule of investments, as of March 31, 2005,
and the related statements of operations, and cash flows for the year then ended
and the statement of changes in members' equity - net assets and the financial
highlights for the year ended March 31, 2005 and for the period December 1, 2003
(commencement of operations) through March 31, 2004. These financial statements
and financial highlights are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits.

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 audits to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material misstatement.
The Company 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 Company's internal control
over financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. Our procedures included confirmation
of investment funds owned as of March 31, 2005, by correspondence with
management of the investment funds; where replies were not received, we
performed other auditing procedures. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Excelsior Absolute Return Fund
of Funds Master Fund, LLC as of March 31, 2005, and the results of its
operations and its cash flows for the year then ended and the changes in
members' equity - net assets and the financial highlights for the years ended
March 31, 2005 and for the period December 1, 2003 (commencement of operations)
through March 31, 2004, in conformity with accounting principles generally
accepted in the United States of America.

- --------------------------------------------------------------------------------

1. 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 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 advisor of the
Company (the "Advisor"). The Advisor is a wholly-owned subsidiary of U.S. Trust
Corporation, and is registered as an investment adviser under the Investment
Advisers Act of 1940, as amended. The Advisor is responsible for developing,
implementing and supervising the investment program and providing day-to-day
management services.

The Advisor has retained AIG Global Investment Corp., an indirect wholly-owned
subsidiary of American International Group, Inc., to serve as the investment
manager (the "Manager"). The Manager 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 Advisor.

The Company's Board of Managers (the "Managers") 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 Company was established to hold substantially all of the assets of Excelsior
Absolute Return Fund of Funds, LLC and Excelsior Absolute Return Fund of Funds,
Ltd. as Members. As of March 31, 2005, Excelsior Absolute Return Fund of Funds,
LLC and Excelsior Absolute Return Fund of Funds, Ltd. ownership of the Company's
members' equity - net assets were 89.30% and 10.70%, respectively.

                                       Notes to Financial Statements (continued)
                                                                  March 31, 2005
- --------------------------------------------------------------------------------

1. Organization (continued)

Member subscriptions for investment interests by eligible investors may be
accepted as of the first day of each calendar quarter, or at such times as the
Managers may determine. The Managers reserve the right to reject any application
for interests in the Company. The Company may, from time to time, offer to
repurchase interests from members pursuant to written tenders by members. These
repurchases will be made at such times and on such terms as may be determined by
the Managers, in their sole discretion, subject to the liquidity of the
Company's assets and other factors considered by the Managers. The Advisor
expects that, generally, it will recommend to the Managers that the Company
offer to repurchase interests from members twice in each year, at June 30th and
December 31st. Members can only transfer or assign their 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
Advisor as of the close of business at the end of any 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 Managers.

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.






                        Excelsior Absolute Return Fund of Funds Master Fund, LLC
                                       Notes to Financial Statements (continued)
                                                                  March 31, 2005
- --------------------------------------------------------------------------------

2. Significant Accounting Policies (continued)

a. Portfolio Valuation (continued)

As a general matter, the fair value of the Company's interest in an Investment
Fund will represent the amount that the Advisor 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 Advisor believes to be reliable. The Advisor or,
in certain cases, the Managers, 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 Managers, 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
Managers. 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, if
any, any excess as a realized gain from investments in investment fund.

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 Managers; all costs with respect to communications regarding the Company's
transactions among the Advisor and any custodian or other agent engaged by the
Company; and other types of expenses approved by the Managers.

                                                                  March 31, 2005
- --------------------------------------------------------------------------------

2. Significant Accounting Policies (continued)

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 since 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 the fiscal period in accordance with each member's respective
investment percentages 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, 2004. Based on Investment Funds owned at December 31, 2004, the cost of
investments for federal income tax purposes was $221,169,866. This consisted of
aggregate gross unrealized appreciation of $6,972,038 and aggregate gross
unrealized depreciation of $270,806.

3. Due to Custodian

Due to Custodian is a result of the Company investing $21,200,000 at March 31,
2005 in investments in Investment Funds effective April 1, 2005. This
$21,200,000 investment was made based upon member subscriptions of $22,741,949
received April 1, 2005. On April 1, 2005 the Company repaid the custodian the
full amount of $19,698,746.

4. Advisory Fee, Related Party Transactions and Other

The Company pays the Advisor a quarterly advisory fee at an annual rate of 1%,
based on the Company's net assets on the first business day of each month, after
adjustments for any subscriptions effective on that date. For the year ended
March 31, 2005, the advisory fee was $2,011,297, of which $627,024 was included
in Due to Advisor as of March 31, 2005.

                                       Notes to Financial Statements (continued)
                                                                  March 31, 2005
- --------------------------------------------------------------------------------

4. Advisory Fee, Related Party Transactions and Other (continued)

The Advisor paid $148,761 of certain reimbursable operating expenses and
organizational costs on behalf of the Company for the year ended March 31, 2005,
of which all is payable to the Advisor as of March 31, 2005.

The Company has retained J.D. Clark & Co. to provide accounting and certain
administrative and investor services to the Company for a fixed fee as agreed
from time to time. For the year ended March 31, 2005, the Company incurred
$24,000 in expenses related to such administrative services, of which $6,000 was
payable as of March 31, 2005. On March 1, 2005 the Managers approved a new
agreement with J.D. Clark & Co beginning April 1, 2005.

5. 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.

6. Investments in Investment Funds

As of March 31, 2005, the Company had investments in twenty-six 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.

Aggregate purchases and proceeds of interests in Investment Funds for the year
ended March 31, 2005 are $168,500,000 and $13,862,933, respectively.

Advance investment in Investment Funds of $21,200,000 represents amounts
transferred to Investment Funds prior to or as of March 31, 2005 and relates to
the investments to be made effective April 1, 2005 pursuant to each Investment
Fund's offering memorandum or member limited partnership agreement.

*   Commencement of Operations.  The ratios and total return are not annualized
    for the period.
(a) Ratio doesn't reflect the Company's proportionate share of the net income
    (loss) and expenses, including incentive allocation, of the Investment
    Funds.
(b) Average members' equity - net assets is determined using the net assets at
    the end of each month during the period.
(c) Total return assumes a purchase of an interest in the Company
    on the first day and a sale of interest on the last day of the period.

8. Subsequent Events

As of April 1, 2005, the Company received subscriptions from members in the
amount of $22,741,949. These subscriptions became interests in the Company
effective April 1, 2005. The Company also invested $21,200,000 in ten existing
Investment Funds as of April 1, 2005, which is reflected as Advance investment
in Investment Funds on the Statement of Assets, Liabilities and Members' Equity
- - Net Assets.

9. 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.
