SEI LIQUID ASSET TRUST -- JUNE 30, 2008

To Our Shareholders:

For the fiscal year ended on June 30, 2008, the fixed income markets experienced
turbulent conditions as escalating delinquencies and defaults on sub-prime
mortgages triggered a flight to safety into U.S. Treasury obligations. The macro
economy was also under pressure as manufacturing activity, consumer spending,
and employment all showed weakness. In response, the Federal Reserve (Fed) took
aggressive measures to promote market liquidity and ensure financial stability.
During the 12-month period, the Fed cut the Fed funds target rate from 5.25% to
2.00%. In addition, the Fed lowered the discount rate by 4.00% and created two
new lending facilities (the Treasury Securities Lending Facility and the Primary
Dealer Credit Facility), which for the first time provided direct financing to
primary dealers. Globally, foreign central banks also joined the Fed in
providing liquidity to the markets through emergency lending facilities.

During the period, 3-month Treasury yields fell from 4.86% to 1.73%, while the
3-month Libor yield declined from 5.36% to 2.78%. Investor risk aversion pushed
asset-backed commercial paper (ABCP) spreads significantly wider, while
unsecured corporate CP widened in sympathy, but to a lesser degree. Yield
spreads on certain bank and financial issuers rose to such a degree that the
programs withdrew from the market. Several Structured Investment Vehicles
(SIVs), a subset of ABCP, had difficulty in rolling their paper when market
conditions caused the market value of the underlying collateral to decline.

From an issuance perspective, Fed data shows that commercial paper outstanding
declined sharply during the period. Total commercial paper outstanding dropped
by about $400 billion, mainly due to the decline in ABCP outstandings. In spite
of the negative headlines, money market funds continued to receive record cash
inflows. By the end of the period, total assets of U.S. money market funds
exceeded $3.4 trillion.

The Prime Obligation Fund (the "Fund") has been impacted by the deterioration in
the credit markets, in that the Fund has exposure to SIVs. SEI and the Fund's
sub-advisor, Columbia Management Advisors, LLC, a Bank of America subsidiary,
are actively monitoring market events, and are committed to delivering the core
investment goals of the Fund, namely preservation of principal and liquidity.

Sincerely,


/s/ Robert A. Nesher

Percentages are based on Net Assets of $1,179,542 ($ Thousands).

(A)  Floating Rate Security. The rate reflected on the Schedule of Investments
     is the rate in effect on June 30, 2008. The demand and interest rate reset
     features give this security a shorter effective maturity date.

(B)  Securities considered illiquid. The total value of such securities as of
     June 30, 2008 was $88,855 ($ Thousands) and represented 7.53% of Net
     Assets.

     registration under Section 144A of the Securities Act of 1933, as amended,
     and may be sold only to dealers in that program or other "accredited
     investors."

(D)  Securities are held in connection with a letter of credit issued by a major
     bank.

(E)  Tri-Party Repurchase Agreement.

(F)  The rate reported is the effective yield at time of purchase.

(G)  The fund has entered into a Capital Support Agreement ("Agreement") with
     SEI Investments Company ("SEI") which provides that SEI will contribute
     capital to the fund, up to a specified maximum amount, in the event that
     the Fund realizes a loss on any of these securities and such realized loss
     causes the Fund's net asset value as calculated using fair value to drop
     below $0.995. As of June 30, 2008, the fair value of the Agreement was
     $11,476 ($ Thousands).

(I)  These securities are considered restricted. The total value of such
     securities as of June 30, 2008 was $88,855 ($ Thousands) and represented
     7.53% of Net Assets.

(J)  On October 17, 2008, due to deterioration in the market value of the assets
     of Cheyne Finance, LLC ("Cheyne"), provisions in the organizational
     documents of Cheyne were triggered that caused the notes issued by Cheyne
     to become immediately due and payable. Since no payments have been
     received, the Cheyne notes are in default.

(K)  On January 18, 2008, due to deterioration in the market value of the assets
     of Stanfield Victoria Finance, LLC ("Victoria"), provisions in the
     organizational documents of Victoria were triggered that caused the notes
     issued by Victoria to become immediately due and payable. Since no payments
     have been received, the Victoria notes are in default.

(L)  On November 21, 2007, due to deterioration in the market value of the
     assets of Axon Financial Funding, LLC ("Axon"), provisions in the
     organizational documents of Axon were triggered that caused the notes
     issued by Axon to become immediately due and payable. Since no payments
     have been received, the Axon notes are in default.

(M)  Notes issued by Issuer Entity LLC were received by the Fund in connection
     with a restructuring of Ottimo Funding Ltd. ("Ottimo") on November 2, 2007.
     The Fund previously held notes issued by Ottimo, which defaulted prior to
     the restructuring.

Notes to Financial Statements

June 30, 2008

1. ORGANIZATION

SEI Liquid Asset Trust (the "Trust") was organized as a Massachusetts business
trust under a Declaration of Trust dated July 20, 1981.

The Trust is registered under the Investment Company Act of 1940, as amended, as
a diversified, open-end management investment company with one fund: the Prime
Obligation Fund (the "Fund"). The Trust is registered to offer Class A shares of
the Fund. A description of the Fund's investment objectives, policies, and
strategies are provided in the prospectus.

2. SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies followed by the
Trust.

USE OF ESTIMATES -- The preparation of financial statements in conformity with
U.S. generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of increases and decreases in
net assets from operations during the reporting period. Actual results could
differ from those estimates.

SECURITY VALUATION -- Investment securities are stated at amortized cost, which
approximates market value. Under this valuation method, purchase discounts and
premiums are accreted and amortized ratably to maturity.

REPURCHASE AGREEMENTS -- The Fund invests in tri-party repurchase agreements.
Securities held as collateral for tri-party repurchase agreements are maintained
in a segregated account by the broker's custodian bank. Provisions of the
agreements and the Trust's policies ensure that the market value of the
collateral, including accrued interest thereon, is sufficient to cover interest
and principal in the event of default by the counterparty. If the counterparty
defaults and the value of the collateral declines or if the counterparty enters
an insolvency proceeding, realization of the collateral by the Fund may be
delayed or limited.

EXPENSES -- Expenses that are directly related to the Fund are charged directly
to the Fund.

SECURITY TRANSACTIONS AND INVESTMENT INCOME -- Security transactions are
accounted for on the trade date. Costs used in determining realized gains and
losses on the sale of investment securities are on the basis of specific
identification. Interest income is recognized using the accrual basis of
accounting.

All amortization is calculated using the straight line method over the holding
period of the security. Amortization of premiums and accretion of discounts are
included in interest income.

DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- Dividends from net investment
income are declared on a daily basis and are payable on the first business day
of the following month. Any net realized capital gains of the Fund are
distributed to the shareholders of the Fund annually.

3. AGREEMENTS AND OTHER TRANSACTIONS WITH AFFILIATES

ADMINISTRATION AND TRANSFER AGENCY AGREEMENT -- SEI Investments Global Funds
Services (the "Administrator") provides administrative services to the Trust for
an annual fee, which is calculated daily and paid monthly, of .42% of the
average daily net assets of the Fund.

The Administrator has contractually agreed to waive fees and to reimburse
expenses, through June 30, 2008, in order to keep total operating expenses, net
of SEI Investments Management Corporation ("SIMC") and SEI Investments
Distribution Co.'s (the "Distributor") fee waivers, from exceeding .44% of the
average daily net assets of the Fund. The Distributor is a wholly-owned and
operated subsidiary of SEI Investments Company and a registered broker-dealer.

DISTRIBUTION AGREEMENT -- The Distributor acts as the distributor of the shares
of the Trust under a Distribution Agreement. The Trust has adopted a shareholder
servicing plan for its Class A shares (the "Class A Plan") pursuant to which a
shareholder servicing fee of up to .25% of the average daily net assets
attributable to Class A shares will be paid to the Distributor. Under the Class
A Plan the Distributor may perform, or may compensate other service providers
for performing, certain shareholder and administrative services. The Distributor
has waived, on a voluntary basis, all of its shareholder servicing fee.

Under the Class A Plan, the Distributor may retain as a profit any difference
between the fee it receives and the amount it pays to third parties.

Certain officers and/or trustees of the Trust are also officers and/or directors
of the Administrator or SIMC. Compensation of officers and affiliated trustees
of the Trust is paid by the Administrator and/or SIMC.

The services provided by the Chief Compliance Officer ("CCO") and his staff,
whom are employees of the Administrator, are paid for by the Trust as incurred.
The services include regulatory oversight of the Trust's advisors, sub-advisors
and service providers as required by SEC regulations. The CCO's services have
been approved by and are reviewed by the Board.

U.S. Bank, N.A. which is a Trust shareholder, acts as custodian and wire agent
for the Trust.

CAPITAL SUPPORT AGREEMENT -- The Fund has entered into a Capital Support
Agreement with SEI Investments Company. Please see Note 8 for more information.


           8  SEI Liquid Asset Trust / Annual Report / June 30, 2008



4. INVESTMENT ADVISORY AGREEMENT

SIMC serves as the Fund's investment adviser and "manager of managers" under an
investment advisory agreement. For its services, SIMC receives an annual fee
equal to .075% of the Trust's average daily net assets up to $500 million and
..02% of such net assets in excess of $500 million.

Columbia Management Advisors, LLC ("Columbia"), serves as the Fund's investment
sub-adviser under an investment sub-advisory agreement. Columbia is paid by
SIMC. SIMC compensates Columbia out of the fee it receives from the Fund.

5. FEDERAL INCOME TAXES

It is the Fund's intention to continue to qualify as a regulated investment
company under Subchapter M of the Internal Revenue Code and distribute all of
its taxable income. Accordingly, no provision for Federal income taxes is
required. The timing and characterization of certain income and capital gains
distributions are determined annually in accordance with Federal tax regulations
which may differ from U.S. generally accepted accounting principles. As a
result, net investment income (loss) and net realized gain (loss) on investment
transactions for the reporting period may differ from distributions during such
period. These book/tax differences may be temporary or permanent in nature. To
the extent these differences are permanent, they are charged or credited to
paid-in capital, undistributed net investment income or accumulated net realized
gain, as appropriate, in the period that the differences arise. These
reclassifications, which have no impact on net asset value of the Fund, are
primarily attributable to reclass of distributions and tax treatment of paydown
gain (loss) on mortgage and asset-backed securities. Accordingly, the following
permanent differences have been reclassified to/from the following accounts
during the year ended June 30, 2008:



Undistributed Net      Accumulated Net
Investment Income   Realized Gain (Loss)
- -----------------   --------------------
                 
    $(174,508)            $174,508


The tax character of dividends paid to Class A shareholders during the years
ended June 30, 2008 and June 30, 2007 were as follows ($ Thousands):

         Income
       ----------
    
2008    $40,418
2007    $41,318


As of June 30, 2008, the components of accumulated losses on a tax basis were as
follows ($ Thousands):


                             
Undistributed Ordinary Income   $ 1,861
Capital Loss Carryforwards          (48)

   Total Accumulated Losses     $(5,685)
                                =======


Post-October losses represent losses realized on investment transactions from
November 1, 2007 through June 30, 2008, that, in accordance with Federal income
tax regulations, the Fund defers and treats as having arisen in the following
fiscal year. For Federal income tax purposes, capital loss carryforwards
represent realized losses of the Fund that may be carried forward for a maximum
period of eight years and applied against future capital gains were as follows:


                                   
Expiring in 2011                      $(39)

The Federal tax cost and aggregate gross unrealized appreciation and
depreciation on investments held by the Fund at June 30, 2008 were as follows:



                                                                        Net

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

In June 2006, the Financial Accounting Standards Board (FASB) issued FASB
Interpretation 48 (FIN 48), "Accounting for Uncertainty in Income Taxes." This
standard defines the threshold for recognizing the benefits of tax-return
positions in the financial statements as "more-likely-than-not" to be sustained
by the taxing authority and requires measurement of a tax position meeting the
more-likely-than-not criterion, based on the largest benefit that is more than
50 percent likely to be realized. FIN 48 is effective as of the beginning of the
first fiscal year beginning after December 15, 2006. At adoption, companies had
to adjust their financial statements to reflect only those tax positions that
are more-likely-than-not to be sustained as of the adoption date. FIN 48 is
applied to all open tax years as of the effective date. Based on its analysis,
management has determined that the adoption of FIN 48 did not have a material
impact to the Fund's financial statements' upon adoption.

Notes to Financial Statements (Concluded)

June 30, 2008

6. NEW ACCOUNTING PRONOUNCEMENTS

In September 2006, the FASB issued Statement on Financial Accounting Standards
("SFAS") No. 157, "Fair Value Measurements." This standard establishes a single
authoritative definition of fair value, sets out a framework for measuring fair
value and requires additional disclosures about fair value measurements. SFAS
No. 157 applies to fair value measurements already required or permitted by
existing standards. SFAS No. 157 is effective for financial statements issued
for fiscal years beginning after November 15, 2007 and interim periods within
those fiscal years. The changes to current generally accepted accounting
principles from the application of this Statement relate to the definition of
fair value, the methods used to measure fair value, and the expanded disclosures
about fair value measurements. As of June 30, 2008, the Fund does not believe
the adoption of SFAS No. 157 will impact the amounts reported in the financial
statements; however, additional disclosures may be required about the inputs
used to develop the measurements and the effect of certain of the measurements
reported in the financial statements for a fiscal period.

7. RESTRUCTURING FUND

At a meeting held on June 29, 2007, the Board approved the liquidation of the
Trust in connection with a limited restructuring of some SEI Funds, in which
case it was planned that nearly all of the Prime Obligation Fund's shareholders
would become shareholders of a Prime Obligation Fund that is being established
within another trust in the SEI Funds Complex. However, in light of recent
volatility in the money markets, the liquidation has been postponed. The adviser
and the Board will continue to monitor the situation to determine when and if
the restructuring and the related liquidation of the Trust should proceed.
Unless and until such liquidation occurs, the Fund will continue to operate
normally.

Accounting rules require that financial statements for entities in liquidation,
or for which liquidation appears imminent, be prepared on a liquidation basis of
accounting. Liquidation basis of accounting requires the Fund to record assets
and liabilities at values expected to be achieved in liquidation. A change to
the liquidation basis of accounting would not have a material effect on the
Fund's carrying value of assets and liabilities nor its operations.

8. CAPITAL SUPPORT AGREEMENT

On December 3, 2007, the Fund entered into a Capital Support Agreement, as
amended with SEI Investments Company ("SEI"), which is the parent company of
SIMC. The Capital Support Agreement requires SEI to commit capital to the Fund,
subject to the aggregate limit of $1.5 million, if the Fund realizes payments or
sales proceeds from specified securities ("Eligible Notes") held by the Fund
which are less than the amortized cost of such securities and such loss causes
the Fund's mark-to-market net asset value to drop below $0.9950. The Eligible
Notes held in the Fund as of June 30, 2008 are presented in the footnotes on the
Schedule of Investments. On June 18, 2008, the Agreement was amended to increase
the maximum contribution amount to $12.5 million. Upon the sale or other
disposition of an Eligible Note, the amount of required capital commitment would
be the least of the following amounts: (i) the amount, if any, by which the
amortized cost of the Eligible Note exceeds the amount realized from the sale or
other disposition of the security; (ii) the amount, if any, necessary to restore
the net asset value per share of the Fund to $0.9950, or (iii) the remaining
amount of the aggregate limit of the Capital Support Agreement, taking into
account all prior contributions. SEI's obligations under the Agreement are
supported by a Letter of Credit issued by a bank having a First Tier credit
rating. The Fund will draw on the Letter of Credit in the event that SEI fails
to make a cash contribution when due under the Agreement.

The Fund will sell the Eligible Notes (i) promptly following any change in the
Letter of Credit provider's short term credit ratings such that the Letter of
Credit provider's obligations no longer qualify as First Tier Securities as
defined in paragraph (a)(12) of Rule 2a-7, or (ii) on the business day
immediately prior to the termination date of the Agreement; provided that the
Fund is not required to complete any such sale if the amount the Fund expects to
receive would not result in the payment of a Capital Contribution, or, with
respect to an event described in (i) above, if the Affiliate substitutes an
obligation or credit support that satisfies the requirement of a First Tier
Security within fifteen (15) calendar days from the occurrence of such event
and, during such 15 day period, the Letter of Credit provider's obligations
continue to qualify as Second Tier Securities under paragraph (a)(22) of Rule
2a-7. The termination date of the Agreement is December 1, 2008, although that
date may be extended upon agreement of SEI and the Fund, subject to the prior
approval of the staff of the U.S. Securities and Exchange Commission.

9. SUBSEQUENT EVENTS

SIV Portfolio PLC (formerly Cheyne Finance PLC) (the "Cheyne SIV") is a
structured investment vehicle that defaulted on its notes in October, 2007.
Receivers were appointed with the responsibility to liquidate the assets of the
structure and deliver the proceeds to the noteholders. As an alternative to
accepting the proceeds from the auction of the underlying collateral in the
current market environment, the receivers retained an investment banking firm to
create a structure that would enable electing noteholders to exchange their
notes in the Cheyne SIV for pass-through notes in a new vehicle (Gryphon Funding
Limited) that would acquire and hold a pro rata portion of the underlying
collateral of the Cheyne SIV. The liquidation/restructuring of the Cheyne SIV
took place in July 2008. In connection with that process, the Fund elected to
exchange its Cheyne SIV notes for notes issued by Gryphon Funding Limited. This
exchange settled in the Fund's account on July 23, 2008.

On July 30, 2008, the Capital Support Agreement was amended to increase the
maximum contribution amount to $20 million. As of August 26, 2008, the Capital
Support Agreement is valued at $17,912,100 for the Fund.

SEI LIQUID ASSET TRUST -- JUNE 30, 2008

Report of Independent Registered Public Accounting Firm

To the Board of Trustees and Shareholders of
SEI Liquid Asset Trust:

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of SEI Liquid Asset Trust, comprising the Prime
Obligation Fund (the "Fund"), as of June 30, 2008, and the related statement of
operations for the year then ended, the statements of changes in net assets for
each of the years in the two-year period then ended and the financial highlights
for each of the years in the three-year period then ended. These financial
statements and financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audits. The financial
highlights for each of the years in the two-year period ended June 30, 2005,
were audited by other auditors, whose report dated August 19, 2005 expressed an
unqualified opinion thereon.

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. 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 June 30, 2008, by correspondence with the custodians and
brokers or other appropriate auditing procedures. 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 the
fund comprising SEI Liquid Asset Trust as of June 30, 2008, and the results of
its operations for the year then ended, the changes in its net assets for each
of the years in the two-year period then ended, and the financial highlights for
each of the years in the three-year period then ended, in conformity with U.S.
generally accepted accounting principles.

Disclosure of Fund Expenses (Unaudited)

All mutual funds have operating expenses. As a shareholder of a mutual fund,
your investment is affected by these ongoing costs, which include (among others)
costs for portfolio management, administrative services, and shareholder reports
like this one. It is important for you to understand the impact of these costs
on your investment returns.

Operating expenses such as these are deducted from a mutual fund's gross income
and directly reduce your final investment return. These expenses are expressed
as a percentage of a mutual fund's average net assets; this percentage is known
as a mutual fund's expense ratio. The following examples use the expense ratio
and are intended to help you understand the ongoing costs (in dollars) of
investing in your Fund and to compare these costs with those of other mutual
funds. The examples are based on an investment of $1,000 made at the beginning
of the period shown and held for the entire period.

The table below illustrates your Fund's costs in two ways:

- -    ACTUAL FUND RETURN. This section helps you to estimate the actual expenses
     after fee waivers that your Fund incurred over the period. The "Expenses
     Paid During Period" column shows the actual dollar expense cost incurred by
     a $1,000 investment in the Fund, and the "Ending Account Value" number is
     derived from deducting that expense cost from the Fund's gross investment
     return.

You can use this information, together with the actual amount you invested in
the Fund, to estimate the expenses you paid over that period. Simply divide your
ending account value by $1,000 to arrive at a ratio (for example, an $8,600
account value divided by $1,000 = 8.6), then multiply that ratio by the number
shown for your Fund under "Expenses Paid During Period."

- -    HYPOTHETICAL 5% RETURN. This section helps you compare your Fund's costs
     with those of other mutual funds. It assumes that the Fund had an annual 5%
     return before expenses during the year, but that the expense ratio (Column
     3) for the period is unchanged. This example is useful in making
     comparisons because the Securities and Exchange Commission requires all
     mutual funds to make this 5% calculation. You can assess your Fund's
     comparative cost by comparing the hypothetical result for your Fund in the
     "Expenses Paid During Period" column with those that appear in the same
     charts in the shareholder reports for other mutual funds.

NOTE: Because the return is set at 5% for comparison purposes -- NOT your Fund's
actual return -- the account values shown may not apply to your specific
investment.

     average account value over the period, multiplied by 182/366 (to reflect
     the one-half year period shown).

agreements (the "Sub-Advisory Agreements" and, together with the Advisory
Agreement, the "Investment Advisory Agreements") with SIMC, and under the
supervision of SIMC and the Trust's Board of Trustees (the "Board"), the
Sub-Advisers are responsible for the day-to-day investment management of all or
a discrete portion of the assets of the Funds. The Sub-Advisers also are
responsible for managing their employees who provide services to these Funds.
The Sub-Advisers are selected based primarily upon the research and
recommendations of SIMC, which evaluates quantitatively and qualitatively the
Sub-Advisers' skills and investment results in managing assets for specific
asset classes, investment styles and strategies.

The Investment Company Act of 1940, as amended (the "1940 Act") requires that
the initial approval of, as well as the continuation of, the Funds' Investment
Advisory Agreements must be specifically approved: (i) by the vote of the Board
of Trustees or by a vote of the shareholders of the Funds; and (ii) by the vote
of a majority of the Trustees who are not parties to the Investment Advisory
Agreements or "interested persons" of any party (the "Independent Trustees"),
cast in person at a meeting called for the purpose of voting on such approval.
In connection with their consideration of such approvals, the Funds' Trustees
must request and evaluate, and SIMC and the Sub-Advisers are required to
furnish, such information as may be reasonably necessary to evaluate the terms
of the Investment Advisory Agreements. In addition, the Securities and Exchange
Commission ("SEC") takes the position that, as part of their fiduciary duties
with respect to a mutual fund's fees, mutual fund boards are required to
evaluate the material factors applicable to a decision to approve an Investment
Advisory Agreement.

Consistent with these responsibilities, the Trust's Board of Trustees calls and
holds meetings each year that are dedicated to considering whether to renew the
Investment Advisory Agreements between the Trust and SIMC and SIMC and the
Sub-Advisers with respect to the Funds of the Trust. In preparation for these
meetings, the Board requests and reviews a wide variety of materials provided by
SIMC and the Sub-Advisers, including information about SIMC's and the
Sub-Advisers' affiliates, personnel and operations. The Board also receives
extensive data provided by third parties. This information is in addition to the
detailed information about the Funds that the Board reviews during the course of
each year, including information that relates to Fund operations and Fund
performance. The Trustees also receive a memorandum from Fund counsel and
independent counsel to the Independent Trustees regarding the responsibilities
of Trustees in connection with their consideration of whether to approve the
Trust's Investment Advisory Agreements. Finally, the Independent Trustees
receive advice from independent counsel to the Independent Trustees, meet in
executive session outside the presence of Fund management and participate in
question and answer sessions with representatives of SIMC and the Sub-Advisers.

Specifically, the Board requested and received written materials from SIMC and
the Sub-Advisers regarding: (a) the quality of SIMC's and the Sub-Advisers'
investment management and other services; (b) SIMC's and the Sub-Advisers'
investment management personnel; (c) SIMC's and the Sub-Advisers' operations and
financial condition; (d) SIMC's and the Sub-Advisers' brokerage practices
(including any soft dollar arrangements) and investment strategies; (e) the
level of the advisory fees that SIMC and the Sub-Advisers charge the Funds
compared with the fees each charge to comparable mutual funds; (f) the Funds'
overall fees and operating expenses compared with similar mutual funds; (g) the
level of SIMC's and the Sub-Advisers' profitability from their Fund-related
operations; (h) SIMC's and the Sub-Advisers' compliance systems; (i) SIMC's and
the Sub-Advisers' policies on and compliance procedures for personal securities
transactions; (j) SIMC's and the Sub-Advisers' reputation, expertise and
resources in domestic and/or international financial markets; and (k) the Funds'
performance compared with similar mutual funds.

At the March 12-13, 2008 meetings of the Board of Trustees, the Trustees,
including a majority of the Independent Trustees, approved the Investment
Advisory Agreements and approved the selection of SIMC and the Sub-Advisers to
act in their respective capacities for the Funds. The Board's approval was based
on its consideration and evaluation of a variety of specific factors discussed
at the meetings and at prior meetings, including:

- -    the nature, extent and quality of the services provided to the Funds under
     the Investment Advisory Agreements, including the resources of SIMC and the
     Sub-Advisers and their affiliates dedicated to the Funds;

- -    the Funds' investment performance and how it compared to that of other
     comparable mutual funds;

- -    the Funds' expenses under each Investment Advisory Agreement and how those
     expenses compared to those of other comparable mutual funds;


           SEI Liquid Asset Trust / Annual Report / June 30, 2008  17


Board of Trustees Considerations in Approving the Advisory and Sub-Advisory
Agreements (Unaudited) (Concluded)

- -    the profitability of SIMC and the Sub-Advisers and their affiliates with
     respect to the Funds, including both direct and indirect benefits accruing
     to SIMC and the Sub-Advisers and their affiliates; and

- -    the extent to which economies of scale would be realized as the Funds grow
     and whether fee levels in the Investment Advisory Agreements reflect those
     economies of scale for the benefit of Fund investors.

NATURE, EXTENT AND QUALITY OF SERVICES. The Board of Trustees considered the
nature, extent and quality of the services provided by SIMC and the Sub-Advisers
to the Funds and the resources of SIMC and the Sub-Advisers and their affiliates
dedicated to the Funds. In this regard, the Trustees evaluated, among other
things, SIMC's and the Sub-Advisers' personnel, experience, track record and
compliance program. The Trustees found the level of SIMC's professional staff
and culture of compliance satisfactory. Following evaluation, the Board
concluded that, within the context of its full deliberations, the nature, extent
and quality of services provided by SIMC and the Sub-Advisers to the Funds and
the resources of SIMC and the Sub-Advisers and their affiliates dedicated to the
Funds supported renewal of the Investment Advisory Agreements.

FUND PERFORMANCE. The Board of Trustees considered Fund performance in
determining whether to renew the Investment Advisory Agreements. Specifically,
the Trustees considered the Funds' performance relative to their peer groups and
appropriate indices/benchmarks, in light of total return, yield and market
trends. As part of this review, the Trustees considered the composition of each
peer group and selection criteria. In evaluating performance, the Trustees
considered both market risk and shareholder risk expectations for the Funds. The
Trustees found Fund performance satisfactory, and where performance was below
the benchmark, the Trustees were satisfied that appropriate steps were being
taken. Following evaluation, the Board concluded that, within the context of its
full deliberations, the performance of the Funds supported renewal of the
Investment Advisory Agreements.

FUND EXPENSES. With respect to the Funds' expenses under the Investment Advisory
Agreements, the Trustees considered the rate of compensation called for by the
Investment Advisory Agreements and the Funds' net operating expense ratio in
comparison to those of other comparable mutual funds. The Trustees also
considered information about average expense ratios of comparable mutual funds
in the Funds' respective peer groups. The Trustees further considered the fact
that the comparative fee analysis either showed that the various fees were below
average or that there was a reasonable basis for the fee level. Finally, the
Trustees considered the effects of SIMC's voluntary waiver of management and
other fees and the Sub-Advisers' fees to prevent total Fund expenses from
exceeding a specified cap and that SIMC and the Sub-Advisers, through waivers,
have maintained the Funds' net operating expenses at competitive levels for
their respective distribution channels. Following evaluation, the Board
concluded that, within the context of its full deliberations, the expenses of
the Funds are reasonable and supported renewal of the Investment Advisory
Agreements.

PROFITABILITY. With regard to profitability, the Trustees considered all
compensation flowing to SIMC and the Sub-Adviser and their affiliates, directly
or indirectly. The Trustees considered whether the varied levels of compensation
and profitability under the Investment Advisory Agreements and other service
agreements were reasonable and justified in light of the quality of all services
rendered to the Funds by SIMC and the Sub-Advisers and their affiliates. The
Trustees found that profitability was reasonable and that the margin was not
increasing despite growth in assets. When considering the profitability of the
Sub-Advisers, the Board took into account the fact that the Sub-Advisers are
compensated by SIMC, and not by the Funds directly, and such compensation with
respect to any Sub-Adviser reflects an arms-length negotiation between the
Sub-Adviser and SIMC. Based on this evaluation, the Board concluded that, within
the context of its full deliberations, the profitability of SIMC and the
Sub-Advisers are reasonable and supported renewal of the Investment Advisory
Agreements.

ECONOMIES OF SCALE. The Trustees considered the existence of any economies of
scale and whether those were passed along to the Funds' shareholders through a
graduated investment advisory fee schedule or other means, including any fee
waivers by SIMC and its affiliates. Based on this evaluation, the Board
concluded that, within the context of its full deliberations, the Funds obtain
reasonable benefit from economies of scale.

Based on the Trustees' deliberation and their evaluation of the information
described above, the Board, including all of the Independent Trustees,
unanimously approved the continuation of the Investment Advisory Agreements and
concluded that the compensation under the Investment Advisory Agreements is fair
and reasonable in light of such services and expenses and such other matters as
the Trustees considered to be relevant in the exercise of their reasonable
judgment. In the course of their deliberations, the Trustees did not identify
any particular information that was all-important or controlling.

     income.

Notes:
(1)      Audit fees include amounts related to the audit of the Registrant's
         annual financial statements and services normally provided by the
         accountant in connection with statutory and regulatory filings.

(e)(1)   All requests or applications for services to be provided by the
independent auditor shall be submitted to the Chief Financial Officer ("CFO") of
the Registrant and must include a detailed description of the services proposed
to be rendered. The Registrant's CFO will determine whether such services (1)
require specific pre-approval, (2) are included within the list of services that
have received the general pre-approval of the Audit Committee or (3) have been
previously pre-approved in connection with the independent auditor's annual
engagement letter for the applicable year or otherwise.

Requests or applications to provide services that require specific pre-approval
by the Audit Committee will be submitted to the Audit Committee by the CFO. The
Audit Committee will be informed by the CFO on a quarterly basis of all services
rendered by the independent auditor. The Audit Committee has delegated specific
pre-approval authority to either the Audit Committee Chair or financial expert,
provided that the estimated fee for any such proposed pre-approved service does
not exceed $100,000 and any pre-approval decisions are reported to the Audit
Committee at its next regularly scheduled meeting.

All services to be provided by the independent auditor shall be provided
pursuant to a signed written engagement letter with the Registrant, the
investment advisor or applicable control affiliate (except that matters as to
which an engagement letter would be impractical because of timing issues or
because the matter is small may not be the subject of an engagement letter) that
sets forth both the services to be provided by the independent auditor and the
total fees to be paid to the independent auditor for those services.

In addition, the Audit Committee has determined to take additional measures on
an annual basis to meet its responsibility to oversee the work of the
independent auditor and to assure the auditor's independence from the Funds,
such as reviewing a formal written statement from the independent auditor
delineating all relationships between the independent auditor and the
Registrant, and discussing with the independent auditor its methods and
procedures for ensuring independence.

(e)(2) Percentage of fees billed applicable to non-audit services pursuant to
waiver of pre-approval requirement were as follows:

        ---------------------------- ----------------- ----------------
                                           2008             2007
        ---------------------------- ----------------- ----------------
         Audit-Related Fees                  0%               0%

        ---------------------------- ----------------- ----------------
         Tax Fees                            0%               0%

        ---------------------------- ----------------- ----------------
         All Other Fees                      0%               0%

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



(f) Not applicable.

(g)(1) The aggregate non-audit fees and services billed by KPMG for the fiscal
year 2008 were $226,400. Non-audit fees consist of SAS No. 70 review of fund
accounting and administration operations, attestation report in accordance with
Rule 17 Ad-13, agreed upon procedures report over certain internal controls
related to compliance with federal securities laws and regulations and tax
consulting services for various service affiliates of the Registrant.

(g)(2)  The aggregate non-audit fees and services billed by KPMG for the 2007
fiscal year were $231,000.




(h) During the past fiscal year, Registrant's principal accountant provided
certain non-audit services to Registrant's investment adviser or to entities
controlling, controlled by, or under common control with Registrant's investment
adviser that provide ongoing services to Registrant that were not subject to
pre-approval pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X.
The Registrant's Audit Committee reviewed and considered these non-audit
services provided by Registrant's principal accountant to Registrant's
affiliates, including whether the provision of these non-audit services is
compatible with maintaining the principal accountant's independence.

ITEM 5.    AUDIT COMMITTEE OF LISTED REGISTRANTS.

2004, as amended, the Committee will review all shareholder recommendations for
