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

We have audited the accompanying statement of assets, 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, 2004,
and the related statements of operations, cash flows and changes in members'

operations) to March 31, 2004. These financial statements are the responsibility
of the Company's management. Our responsibility is to express an opinion on
these financial statements based on our audit.

We conducted our audit 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 are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of March
31, 2004, by correspondence with management of the investment 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 audit provides 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 at March 31, 2004, the results of its operations, its
cash flows and changes in its members' equity - net assets for the period from
December 1, 2003 (commencement of operations) to March 31, 2004, in conformity

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 advisor 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, 2004, these members' ownership of the Company's
members' equity - net assets were 95.96% and 4.04%, respectively.





                        Excelsior Absolute Return Fund of Funds Master Fund, LLC

                                                                  March 31, 2004
- --------------------------------------------------------------------------------

1. Organization (continued)

Member subscriptions 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 as of
December 31, 2004, and thereafter, twice in each year, at June 30th and December
31st. Members can only transfer or assign their Company interests under certain
limited circumstances or with the written consent of the Managers, which may be
withheld in their sole discretion.

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.

                                       Notes to Financial Statements (continued)
- --------------------------------------------------------------------------------
                                                                  March 31, 2004
- --------------------------------------------------------------------------------

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 reasonable 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, 2004
- --------------------------------------------------------------------------------

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.

For the period from December 1, 2003 (Commencement of Operations) to March 31,
2004, the Company reclassified $388,597 and $8,460 from accumulated net
investment loss and net realized gain from investments, respectively, to capital
subscriptions - net. This reclassification was a result of permanent book-to-tax
differences to reflect, as an adjustment to net capital subscribed, the amounts
of taxable income or loss that have been allocated to the Company's members and
had no effect on net assets.

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, 2003. Based on Investment Funds owned at December 31, 2003, the cost of
investments for federal income tax purposes was $56,370,039. This consisted of
aggregate gross appreciation of $796,995.

d. Other

Cash and cash equivalents consist of monies invested in a PFPC interest-bearing
account. Interest income is recorded on the accrual basis.

3. 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 period from
December 1, 2003 (Commencement of Operations) to March 31, 2004, the advisory
fee was $251,269, of which $204,028 was payable as of March 31, 2004.

                                                                  March 31, 2004
- --------------------------------------------------------------------------------

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

The Advisor paid $99,208 of certain reimbursable operating expenses and
organizational costs on behalf of the Company for the period from December 1,
2003 (Commencement of Operations) to March 31, 2004, of which all is payable to
the Advisor as of March 31, 2004.

4. 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 March 31, 2004, the Company had investments in twenty-one Investment
Funds, none of which were affiliates, as defined by the 1940 Act. An affiliate
is a fund in which the Company has ownership of over 5% of the voting fund's
securities. The Company has waived its voting rights for all investments in
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 period
from December 1, 2003 (Commencement of Operations) to March 31, 2004 is
$78,900,000 and $1,058,460, respectively.

Advance investment in investment funds of $53,500,000 represents amounts
transferred to Investment Funds prior to or as of March 31, 2004 and relates to
the investments to be made effective April 1, 2004 pursuant to each Investment
Fund's offering memorandum or member limited partnership agreement.

6. Financial Highlights

The following represents the ratios to average members' equity - net assets,
total return and other supplemental information for the period from December 1,
2003 (Commencement of Operations) through March 31, 2004:

Net assets, end of period                                           $ 83,029,523
Ratio of net investment loss to average
    members' equity - net assets (a) (c) (d)                             (0.54%)

Ratio of expenses to average members'                                      0.54%
    equity - net assets (a) (c) (d)

Portfolio turnover                                                             -
Total return (a) (b)                                                       5.02%




(a)   The ratios and total return are not annualized for the period.
(b)   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.
(c)   Ratio doesn't  reflect the Company's  proportionate share of the net
      income (loss) and expenses, including incentive allocation, of the
      Investment Funds.
(d)   Average members' equity - net assets is determined using the net assets at
      the end of each month during the period.

7. Subsequent Events

As of March 31, 2004, the Company received subscriptions from members in the
amount of $54,020,208, which is reflected as members' interest received in
advance on the Statement of Assets, Liabilities and Members' Equity - Net
Assets. These subscriptions will become interests in the Company effective April
1, 2004. The Company also invested $53,500,000 in nineteen existing and one new
Investment Funds as of April 1, 2004.

8. 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.
