Chairman's Letter

Dear Shareholder,

I am pleased to present to you this annual report for the Lehman Brothers
Institutional Liquidity Funds for the period ended March 31, 2007. The report
includes portfolio commentary, a listing of the Portfolios' investments, and
their audited financial statements for the reporting period.

After two final 25 basis point increases through June 2006, the Federal Reserve
paused in the policy of monetary tightening it had been pursuing since June of
2004. The Fed has kept the Fed Funds rate at 5.25% at each of its meetings from
June 2006 through March 2007. The central bank continues to articulate concerns
about inflation; it has noted that it will look to future data releases to
assess the impact of past rate increases in containing inflation and
engineering a soft landing for the economy. This will determine whether, in the
view of the Fed, further increases will be necessary or if rates can be reduced.

The Portfolios performed admirably and as expected throughout the period. Our
investment strategy combines a distinct process for interest rate risk
management with dedicated credit research to build a portfolio of high-quality
securities that seeks to respond quickly to changes in interest rates without
sacrificing yield.

As always, we intend to proceed with caution to protect our clients' principal
and maintain daily liquidity and diversification.

Sincerely,

/s/ Peter Sundman

PETER SUNDMAN
CHAIRMAN OF THE BOARD
LEHMAN BROTHERS INSTITUTIONAL LIQUIDITY FUNDS

                                      1

Institutional Liquidity Funds Portfolio Commentaries

We are pleased to report that both the Money Market Portfolio Institutional
Class and the Prime Portfolio Institutional Class delivered positive returns
and outperformed the iMoneyNet Money Fund Report First Tier Institutional
Average for their first full quarter of operation, from January 1, 2007 through
March 31, 2007.

The Federal Reserve remained on hold throughout the first quarter of 2007, and
at the March 21st meeting, it removed the tightening bias from language in the
accompanying statement. This is a significant shift and suggests that board
members may be a bit more sanguine with respect to economic prospects. During
the reporting period, investors were focused on strains in the U.S. sub-prime
mortgage market, inflationary pressures, and a vibrant U.S. employment picture.
In recent months there has been considerable anxiety surrounding the sub-prime
mortgage market as delinquencies and foreclosures continue to climb higher. The
employment picture remains benign as monthly non-farm payrolls for the quarter
averaged gains of 152,000 and the unemployment rate dropped to 4.4% in March.
The Core Personal Consumption Expenditures (PCE) Price Index, policy makers'
preferred measure of inflation, increased to an annualized rate of 2.4% in
February. This is above Fed officials' avowed comfort levels.

Going forward, we expect the Federal Reserve to leave rates unchanged in the
short term as it assesses the macroeconomic impact of a housing led slowdown on
the broader economy. Inherent problems persist in the sub-prime sector, though
it is unclear whether these problems will permeate to the prime sector.
Inflation remains stubbornly high, although we feel the Federal Reserve will be
hard-pressed to raise short-term rates, despite its confessed willingness to do
so. Ultimately, we anticipate the next move by the Fed will be to take rates
lower, or to take no action and remain neutral. In the interim, we anticipate
that rates will remain in a limited range as the market and the Fed digest
incoming data. We will seek to capitalize on pockets of interest rate
volatility in order to provide consistent and secure returns to our
shareholders.

Money Market Portfolio

For the first full quarter of the portfolio's operation, ending on March 31,
2007, the Money Market Portfolio Institutional Class returned 1.31% compared to
the iMoneyNet Money Fund Report Taxable First Tier Institutional Average's
1.24%. The Portfolio's Institutional Class closed fiscal 2007 with a 5.29%
seven-day current yield and a 5.43% seven-day effective yield; this more
closely reflects current earnings than the six-month or one-year figures.
(Performance information for the other classes of the Portfolio is available in
the chart following this commentary.)

1   Neuberger Berman Management Inc. (NBMI) has contractually agreed to forgo
    current payment of fees and/or reimburse certain expenses of the
    Administrative Class of each Portfolio through 3/31/2010, so that the total
    annual operating expenses of the Administrative Class of each Portfolio are
    limited to 0.45% of its average net assets. This arrangement does not cover
    interest, taxes, brokerage commissions and extraordinary expenses. Each
    Portfolio has agreed that its Administrative Class will repay NBMI for fees
    and expenses foregone or reimbursed for that Class provided that repayment
    does not cause the annual operating expenses of that Class of the Portfolio
    to exceed the above-stated expense limitation and the reimbursements are
    made within three years after the year that Management incurred the
    expense. For the period ended March 31, 2007, if this reimbursement was not
    made, performance would be lower for the Administrative Class of each
    Portfolio.

    commissions and extraordinary expenses. Each Portfolio has agreed that its
    Institutional Class will repay NBMI for fees and expenses foregone or
    reimbursed for that Class provided that repayment does not cause the annual
    operating expenses of that Class of the Portfolio to exceed the
    above-stated expense limitation and the reimbursements are made within
    three years after the year that Management incurred the expense. For the
    period ended March 31, 2007, if this reimbursement was not made,

5   Management has contractually agreed to forgo current payment of fees and/or
    reimburse certain expenses of the Premier Class of each Portfolio through
    3/31/2010, so that the total annual operating expenses of the Premier Class
    of each Portfolio are limited to 0.70% of its average net assets. This
    arrangement does not cover interest, taxes, brokerage commissions and
    extraordinary expenses. Each Portfolio has agreed that its Premier Class
    will repay NBMI for fees and expenses foregone or reimbursed for that Class
    provided that repayment does not cause the annual operating expenses of

8   "Current yield" of a money market fund refers to the income generated by an
    investment in a Portfolio over a recent 7-day period. This income is then
    "annualized." The "effective yield" is calculated similarly but, when
    annualized, the income earned by an investment in the Portfolio is assumed
    to be reinvested. The "effective yield" will be slightly higher than the
    "current yield" because of the compounding effect of this assumed
    reinvestment. Yields of a money market fund will fluctuate and past
    performance is not a guarantee of future results. Unaudited performance
    data current to the most recent month-end are available by calling

Information About Your Portfolio's Expenses

These tables are designed to provide information regarding costs related to
your investments. All mutual funds incur operating expenses, which include each
portfolio's proportionate share of expenses of its corresponding master series,
administrative service fees and other expenses. The following examples are
based on an investment of $1,000 made at the beginning of the period shown and
held for the entire period. The tables illustrate the portfolio's costs in two
ways:

Actual Expenses and            The first section of the table provides
Performance:                   information about actual account values and
                               actual expenses in dollars, based on the
                               portfolio's actual performance during the
                               period. You may use the information in this
                               line, together with the amount you invested, to
                               estimate the expenses you paid over the period.
                               Simply divide your account value by $1,000 (for
                               example, an $8,600 account value divided by
                               $1,000 = 8.6), then multiply the result by the
                               number in the first section of the table under
                               the heading entitled "Expenses Paid During the
                               Period" to estimate the expenses you paid over
                               the period.

Hypothetical Example           The second section of the table provides
for Comparison Purposes:       information about hypothetical account values
                               and hypothetical expenses based on the
                               portfolio's actual expense ratio and an assumed
                               rate of return at 5% per year before expenses.
                               This return is not the portfolio's actual
                               return. The hypothetical account values and
                               expenses may not be used to estimate the actual
                               ending account balance or expenses you paid for
                               the period. You may use this information to
                               compare the ongoing costs of investing in these
                               portfolios versus other funds. To do so, compare
                               the expenses shown in this 5% hypothetical
                               example with the 5% hypothetical examples that
                               appear in the shareholder reports of other funds.

* For each class of the portfolio, expenses are equal to the annualized expense
  ratio for the class, multiplied by the average account value over the period,
  multiplied by 105/365 (to reflect the period shown). Each portfolio's expense
  ratio includes its proportionate share of the expenses of its corresponding
  master series.

**Hypothetical 5% annual return before expenses is calculated by multiplying
  the number of days in the most recent period divided by 365.

^ The date investment operations commenced.

* For each class of the portfolio, expenses are equal to the annualized expense
  ratio for the class, multiplied by the average account value over the period,
  multiplied by 105/365 (to reflect the period shown). Each portfolio's expense
  ratio includes its proportionate share of the expenses of its corresponding
  master series.

**Hypothetical 5% annual return before expenses is calculated by multiplying
  the number of days in the most recent period divided by 365.

^ The date investment operations commenced.

Notes to Financial Statements Institutional Liquidity Funds

Note A--Summary of Significant Accounting Policies:

1   General: Money Market Portfolio ("Money Market"), Prime Portfolio
    ("Prime"), Government Portfolio ("Government"), and Treasury Portfolio
    ("Treasury") (individually a "Portfolio," collectively, the "Portfolios"),
    are separate operating series of Lehman Brothers Institutional Liquidity
    Funds (the "Trust"), a Delaware statutory trust organized pursuant to a
    Trust Instrument dated October 1, 2004. The Trust is registered as a
    diversified, open-end management investment company under the Investment
    Company Act of 1940, as amended (the "1940 Act"), and its shares are
    registered under the Securities Act of 1933 (the "1933 Act"), as amended.
    Each Portfolio (except Government) had no operations until December 18,
    2006, other than matters relating to their organization and registration of
    shares under the 1933 Act. Government had no operations until December 18,
    2006, other than the matters relating to its organization and the sale to
    Neuberger Berman Management Inc., the Portfolio's investment manager
    ("Management"), on December 4, 2006 of 100,000 shares of beneficial
    interest of the Institutional Class for $100,000 ($1.00 per share). Each
    Portfolio offers Institutional Class shares, Cash Management Class shares,
    Capital Class shares, Select Class shares, Administrative Class shares,
    Service Class shares, and Premier Class shares. The Board of Trustees of
    the Trust (the "Board") may establish additional series or classes of
    shares without the approval of shareholders.

    The assets of each Portfolio belong only to that Portfolio, and the
    liabilities of each Portfolio are borne solely by that Portfolio and no
    other series of the Trust.

    Each Portfolio seeks to achieve its investment objective by investing all
    of its net investable assets in a Master Series of Institutional Liquidity
    Trust (each a "Master Series," collectively, the "Master Series") that has
    an investment objective identical to, and a name similar to, that of each
    respective Portfolio. Money Market invests in Money Market Master Series
    (formerly, Institutional Liquidity Portfolio), Prime invests in Prime
    Master Series (formerly, Prime Portfolio), Government invests in Government
    Master Series (commencement of operations December 18, 2006), and Treasury
    invests in Treasury Master Series (commencement of operations December 18,
    2006). The value of each Portfolio's investment in its corresponding Master
    Series reflects the Portfolio's proportionate interest in the net assets of
    its corresponding Master Series (6.62% for Money Market, 37.56% for Prime,
    65.46% for Government, and 100.00% for Treasury, at March 31, 2007). The
    performance of each Portfolio is directly affected by the performance of
    its corresponding Master Series. The financial statements of the Master
    Series, including the Schedules of Investments, are included elsewhere in
    this report and should be read in conjunction with the Portfolios'
    financial statements.

    It is the policy of the Portfolios to maintain a continuous net asset value
    per share of $1.00; the Portfolios have adopted certain investment,
    valuation, and distribution policies, which conform to general industry
    practice, to enable them to do so. However, there is no assurance the
    Portfolios will be able to maintain a stable net asset value per share.
    Each of these Portfolios complies with Rule 2a-7 of the 1940 Act.

    The preparation of financial statements in accordance with U.S. generally
    accepted accounting principles requires Management to make estimates and
    assumptions at the date of the financial statements. Actual results could
    differ from those estimates.

2   Portfolio valuation: Each Portfolio records its investment in its
    corresponding Master Series at value. Investment securities held by the
    corresponding Master Series are valued as indicated in the notes following
    the Master Series' Schedules of Investments.

3   Income tax information: The Portfolios are treated as separate entities for
    U.S. federal income tax purposes. It is the intention of each Portfolio to
    qualify as a regulated investment company by complying with the
    requirements of Subchapter M of the Internal Revenue Code applicable to
    regulated investment companies and to distribute substantially all of its
    earnings to its shareholders. Therefore, no federal income or excise tax
    provision is required.

                                      15


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

    Income distributions and capital gain distributions are determined in
    accordance with income tax regulations, which may differ from U.S.
    generally accepted accounting principles. These differences are primarily
    due to differing treatments of income and gains on various investment
    securities held by each Master Series, timing differences and differing
    characterization of distributions made by each Portfolio as a whole.

    As determined on March 31, 2007, permanent differences resulting from
    different book and tax accounting for distribution redesignations and
    non-deductible 12b-1 fees were reclassified at fiscal year-end. These
    reclassifications had no effect on net income, net asset value or net asset
    value per share of each Portfolio.

    The tax character of distributions paid during the period ended March 31,
    2007 was as follows:


                                  Distributions Paid From:

                                 Ordinary Income   Total
                                      2007         2007

                    Money Market   $1,492,525    $1,492,525
                    Prime          14,021,217    14,021,217
                    Government      6,555,363     6,555,363
                    Treasury        6,750,442     6,750,442


    As of March 31, 2007, the components of distributable earnings (accumulated
    losses) on a U.S. federal income tax basis were as follows:


                           Undistributed     Loss
                             Ordinary    Carryforwards
                              Income     and Deferrals   Total

              Money Market    $113,102       $(110)      $112,992
              Prime         $1,999,670      (6,250)    $1,993,420
              Government    $2,064,101          --     $2,064,101
              Treasury      $2,037,384          --     $2,037,384


    The difference between book and tax basis distributable earnings is
    attributable primarily to timing differences of distribution payments and
    post October loss deferrals.

    To the extent each Portfolio's net realized capital gains, if any, can be
    offset by capital loss carryforwards, it is the policy of each Portfolio
    not to distribute such gains. As determined on March 31, 2007, the
    Portfolios did not have unused capital loss carryforwards available for
    federal income tax purposes to offset net realized capital gains.

    Under current tax law, certain net capital losses realized after October 31
    within the taxable year may be deferred and treated as occurring on the
    first day of the following tax year. For the period ended March 31, 2007,
    the Portfolios elected to defer the following net capital losses arising
    between December 18, 2006 and March 31, 2007:


                              Money Market  $(110)
                              Prime        (6,250)
                              Government       --
                              Treasury         --

4   Distributions to shareholders: Each Portfolio earns income, net of
    expenses, daily on its investment in its corresponding Master Series. It is
    the policy of each Portfolio to declare distributions from net investment
    income on each business day; such distributions are paid or reinvested
    monthly. Distributions from net realized capital gains, if any, will be
    made annually. Income distributions and capital gain distributions to
    shareholders are recorded on the ex-date.

                                      16


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

5   Expense allocation: Certain expenses are applicable to multiple funds.
    Expenses directly attributable to a Portfolio are charged to that
    Portfolio. Expenses of the Trust that are not directly attributed to a
    Portfolio are allocated among the series of the Trust, on the basis of
    relative net assets, except where a more appropriate allocation of expenses
    to each of the series can otherwise be made fairly. Expenses borne by the
    complex of related investment companies, which includes open-end and
    closed-end investment companies for which Management serves as investment
    manager, that are not directly attributed to a Portfolio or the Trust, are
    allocated among the Portfolios and the other investment companies in the
    complex or series thereof, on the basis of relative net assets, except
    where a more appropriate allocation of expenses to each investment company
    in the complex or series thereof can otherwise be made fairly.

    Each Portfolio bears its proportionate share of its corresponding Master
    Series' expenses. Each Portfolio's expenses (other than those allocated to
    a class of the Portfolio) are allocated proportionally each day among the
    classes based on the relative net assets of each class. Expenses
    attributable to a specific class are allocated to that class.

6   Organization expenses: Costs incurred by each Portfolio in connection with
    its organization, which amounted to approximately $26,456, $26,456, and
    $26,456 for Money Market, Prime, and Treasury, respectively, have been
    borne by Management. Government's organization expenses and offering costs
    of approximately $146,951 have also been borne by Management.

7   Other: All net investment income and realized and unrealized capital gains
    and losses of a Master Series are allocated pro rata among its respective
    Portfolios and any other investment companies that invest in that Master
    Series, if any.

8   Indemnifications: Like many other companies, the Trust's organizational
    documents provide that its officers and trustees are indemnified against
    certain liabilities arising out of the performance of their duties to the
    Trust. In addition, both in some of its principal service contracts and in
    the normal course of its business, the Trust enters into contracts that
    provide indemnifications to other parties for certain types of losses or
    liabilities. The Trust's maximum exposure under these arrangements is
    unknown as this could involve future claims against the Trust.

Note B--Management Fees, Administration Fees, Distribution Arrangements, and
Other Transactions with Affiliates:

    Each Portfolio retains Management as its administrator under an
    Administration Agreement. Each Portfolio pays Management an administration
    fee at the annual rate of 0.10% of its average daily net assets under this
    agreement. Additionally, Management retains State Street Bank and Trust
    Company ("State Street") as its sub-administrator under a
    Sub-Administration Agreement. Management pays State Street a fee for all
    services received under the agreement. Each Portfolio indirectly pays for
    investment management services through its investment in its corresponding
    Master Series at the annual rate of 0.08% of average daily net assets (see
    Note B of Notes to Financial Statements of the Master Series).

    For the Service and Premier Class of each Portfolio, Management acts as
    agent in arranging for the sale of class shares without commission and
    bears advertising and promotion expenses. The Board has adopted
    distribution plans (each a "Plan", collectively, the "Plans") with respect
    to these classes, pursuant to Rule 12b-1 under the 1940 Act. The Plans
    provide that, as compensation for administrative and other services
    provided to these classes, Management's activities and expenses related to
    the sale and distribution of these classes, and ongoing services provided
    to investors in these classes, Management receives from each of these
    classes a fee at the annual rate of 0.15% of such Service Class' and 0.25%
    of such Premier Class' average daily net assets. Management receives this
    amount to provide distribution and shareholder servicing for those classes
    and pays a portion of it to institutions that provide such services. Those
    institutions may use the payments for, among other purposes, compensating
    employees engaged in sales and/or shareholder servicing. The amount of fees
    paid by each class during any year may be more or less than the cost of
    distribution and other services provided to that class. NASD rules limit the

                                      17


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

    amount of annual distribution fees that may be paid by a mutual fund and
    impose a ceiling on the cumulative distribution fees paid. The Trust's
    Plans comply with those rules.

    The Trust, on behalf of each Portfolio, has entered into a Shareholder
    Servicing Agreement with Management with respect to the Cash Management,
    Capital, Select, Administrative, Service and Premier Class of each
    Portfolio ("Shareholder Servicing Agreement"). Pursuant to the Shareholder
    Servicing Agreement, Management provides to the shareholders and beneficial
    owners of the Cash Management, Capital, Select, Administrative, Service and
    Premier Class varying levels of shareholder services, some or all of which
    may be provided by banks, trust companies or other institutions that
    provide such shareholder services to their accounts ("Accounts") and their
    account holders and which have entered into a service agreement with
    Management (each, a "Service Organization"). Management may compensate a
    Service Organization for the shareholder services it provides to Accounts
    and account holders pursuant to such service agreement. The Shareholder
    Servicing Agreement requires each of the Cash Management, Capital, Select,
    Administrative, Service and Premier Class to compensate Management for the
    shareholder services provided to that Class. For the shareholder services
    provided pursuant to the Shareholder Servicing Agreement, Management
    receives from the Cash Management, Capital, Select, Administrative, Service
    and Premier Class of each Portfolio a fee at the annual rate of 0.05%,
    0.10%, 0.15%, 0.25%, 0.25%, 0.25%, respectively, of such Class' average
    daily net assets.

                                      18


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

    Management has contractually undertaken to forgo current payment and/or
    reimburse each respective class of each Portfolio for its operating
    expenses plus its pro rata portion of its corresponding Master Series'
    operating expenses (including the fees payable to Management but excluding
    interest, taxes, brokerage commissions and extraordinary expenses)
    ("Operating Expenses") which exceed the expense limitation as detailed in
    the following table:

    Management and Lehman Brothers Asset Management LLC ("LBAM"), sub-adviser
    to each Master Series, are wholly-owned subsidiaries of Lehman Brothers
    Holdings Inc., a publicly-owned holding company. Several individuals who
    are officers and/or trustees of the Trust are also employees of LBAM and/or
    Management.

    Each Portfolio also has a distribution agreement with Management with
    respect to each class of shares. Management receives no compensation under
    it and no commissions for sales or redemptions of shares of beneficial
    interest of each Portfolio, but receives fees from the Service Class and
    Premier Class under their Plans, as described above.

    Each Master Series has an expense offset arrangement in connection with its
    custodian contract. For the period ended March 31, 2007, the impact of this
    arrangement was a reduction of expenses of $431, $4,422, $564, and $1,269
    for Money Market, Prime, Government, and Treasury, respectively.

Note E--Recent Accounting Pronouncements:

    On July 13, 2006, the Financial Accounting Standards Board ("FASB")
    released FASB Interpretation No. 48 "Accounting for Uncertainty in Income
    Taxes" ("FIN 48"). FIN 48 provides guidance for how uncertain tax positions
    should be recognized, measured, presented and disclosed in the financial
    statements. FIN 48 clarifies the accounting for income taxes, by
    prescribing a minimum recognition threshold a tax position is required to
    meet before being recognized in the financial statements. FIN 48 requires
    that a "more-likely-than-not" threshold be met before the benefit of a tax
    position may be recognized in the financial statements and prescribes how
    such benefit should be measured. Adoption of FIN 48 is required for fiscal
    years beginning after December 15, 2006 and is to be applied to all open
    tax years as of the effective date. The Securities and Exchange Commission
    will permit investment companies to delay implementation of FIN 48 until
    September 30, 2007. At this time, Management is evaluating the implications
    of FIN 48 and its impact in the financial statements has not yet been
    determined.

    In September 2006, FASB issued FASB Statement No. 157, "Fair Value
    Measurement" ("SFAS 157"), which defines fair value, establishes a
    framework for measuring fair value, and expands disclosures about fair
    value measurements. SFAS 157 is effective for fiscal years beginning after
    November 15, 2007, and interim periods within those fiscal years.
    Management believes the adoption of SFAS 157 will not have a material
    impact on the Portfolios' financial position or results of operations.

/+/   The per share amounts and ratios which are shown reflect income and
      expenses, including the Portfolio's proportionate share of its
      corresponding Master Series' income and expenses.

/++/  Total return based on per share net asset value reflects the effects of
      changes in net asset value on the performance of the Portfolio during the
      fiscal period and assumes dividends and other distributions, if any, were
      reinvested. Results represent past performance and do not guarantee future
      results. Current returns may be lower or higher than the performance data
      quoted. Investment returns and principal may fluctuate and shares when
      redeemed may be worth more or less than original cost. Total return would
      have been lower if Management had not reimbursed and/or waived certain
      expenses (see Note B of Notes to Financial Statements of Institutional

Report of Independent Registered Public Accounting Firm


To the Board of Trustees of Lehman Brothers Institutional Liquidity Funds
and Shareholders of Money Market Portfolio and Government Portfolio:

We have audited the accompanying statements of assets and liabilities of Money
Market Portfolio and Government Portfolio (two of the series constituting
Lehman Brothers Institutional Liquidity Funds) (collectively the "Portfolios"),
as of March 31, 2007, and the related statements of operations, changes in net
assets and the financial highlights for the period from December 18, 2006
(commencement of operations) to March 31, 2007. These financial statements and
financial highlights are the responsibility of the Portfolios' 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 audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. We were not engaged to perform an audit of the Portfolios'
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 Portfolios' 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 and financial highlights, assessing
the accounting principles used and significant estimates made by management,
and evaluating the overall financial statement presentation. Our procedures
included confirmation of securities owned as of March 31, 2007, by
correspondence with the custodian and brokers. 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 Money
Market Portfolio and Government Portfolio, each a portfolio of Lehman Brothers
Institutional Liquidity Funds, at March 31, 2007, the results of their
operations, changes in their net assets and the financial highlights for the
period from December 18, 2006 (commencement of operations) to March 31, 2007,
in conformity with U.S. generally accepted accounting principles.

Notes to Financial Statements Institutional Liquidity Trust


Note A--Summary of Significant Accounting Policies:

1   General: The Money Market Master Series (formerly, Institutional Liquidity
    Portfolio), Prime Master Series (formerly, Prime Portfolio), Government
    Master Series, and Treasury Master Series (individually a "Master Series,"
    collectively, the "Master Series") are separate operating series of
    Institutional Liquidity Trust (the "Trust"), a Delaware statutory trust
    organized pursuant to a Trust Instrument dated October 1, 2004. The Trust
    is registered as a diversified, open-end management investment company
    under the Investment Company Act of 1940, as amended. Government Master
    Series had no operations until December 18, 2006 other than the
    contribution of beneficial interest from the Institutional Class of
    Government Portfolio and Neuberger Berman Management Inc., ("Management")
    the Master Series' investment manager of $100,000 and $1,000, respectively,
    on December 4, 2006. Treasury Master Series had no operations until
    December 18, 2006.

    Other investment companies sponsored by Management and Lehman Brothers
    Asset Management LLC ("LBAM"), the sub-adviser to the Master Series, whose
    financial statements are not presented herein, also invest in the Master
    Series.

    The assets of each Master Series belong only to that Master Series, and the
    liabilities of each Master Series are borne solely by that Master Series
    and no other series of the Trust.

    The preparation of financial statements in accordance with U.S. generally
    accepted accounting principles requires Management to make estimates and
    assumptions at the date of the financial statements. Actual results could
    differ from those estimates.

2   Portfolio valuation: Investment securities are valued as indicated in the
    notes following the Master Series' Schedule of Investments.

3   Securities transactions and investment income: Securities transactions are
    recorded on trade date for financial reporting purposes. Interest income,
    including accretion of discount (adjusted for original issue discount,
    where applicable), and amortization of premium, where applicable, is
    recorded on the accrual basis. Realized gains and losses from securities
    transactions are recorded on the basis of identified cost and stated
    separately in the Statements of Operations.

4   Income tax information: It is the policy of the Money Market Master Series
    and Prime Master Series and it is the intention of the Government Master
    Series and Treasury Master Series, to comply with the requirements of the
    Internal Revenue Code. It is also the policy of the Money Market Master
    Series and Prime Master Series and the intention of the Government Master
    Series and Treasury Master Series to conduct their operations so that each
    of its investors that are regulated investment companies and invest
    substantially all of their net investable assets therein will continue to
    qualify as such for Money Market Master Series and Prime Master Series and
    so that its investors will be able to qualify as a regulated investment
    company for Government Master Series and Treasury Master Series. Each
    Master Series will be treated as a partnership for U.S. federal income tax
    purposes and is therefore not subject to U.S. federal income tax.

5   Concentration of risk: Money Market Master Series and Prime Master Series
    normally concentrate in the financial services industries; therefore,
    factors influencing the health of those industries could have a significant
    negative effect on these Master Series' performance. These may include
    economic trends, governmental action, changes in interest rates, as well as
    the availability and cost of capital funds.

6   Expense allocation: Certain expenses are applicable to multiple funds.
    Expenses directly attributable to a Master Series are charged to that
    Master Series. Expenses of the Trust that are not directly attributed to a
    series of the Trust are allocated among the series', on the basis of
    relative net assets, except where a more appropriate allocation of expenses
    to each of the Master Series can otherwise be made fairly. Expenses borne
    by the complex of related investment companies, which includes open-end and
    closed-end investment companies for which Management

                                       59


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

    serves as investment manager, that are not directly attributed to a Master
    Series or the Trust, are allocated among the Master Series and the other
    investment companies in the complex or series thereof, on the basis of
    relative net assets, except where a more appropriate allocation of expenses
    to each investment company in the complex or series thereof can otherwise
    be made fairly.

7   Repurchase agreements: Each Master Series may enter into repurchase
    agreements with institutions that Management has determined are
    creditworthy. Each repurchase agreement is recorded at cost. Each Master
    Series requires that the securities purchased in a repurchase agreement be
    transferred to the custodian in a manner sufficient to enable the Master
    Series to assert a perfected security interest in those securities in the
    event of a default under the repurchase agreement. Each Master Series
    monitors, on a daily basis, the value of the securities transferred to
    ensure that their value, including accrued interest, is greater than
    amounts owed to the Master Series under each such repurchase agreement.

8   Indemnifications: Like many other companies, the Trust's organizational
    documents provide that its officers and trustees are indemnified against
    certain liabilities arising out of the performance of their duties to the
    Trust. In addition, both in some of its principal service contracts and in
    the normal course of its business, the Trust enters into contracts that
    provide indemnifications to other parties for certain types of losses or
    liabilities. The Trust's maximum exposure under these arrangements is
    unknown as this could involve future claims against the Trust.

Note B--Management Fees and Other Transactions with Affiliates:

    Each Master Series retains Management as its investment manager under a
    Management Agreement. For such investment management services, prior to
    December 18, 2006, the Money Market Master Series and Prime Master Series
    paid Management a fee at the annual rate of 0.10% of its average daily net
    assets. Management voluntarily agreed to waive its management fee in the
    amount of 0.02% of the average daily net assets of each Master Series. For
    the year ended March 31, 2007, such waived fees amounted to $359,405 for
    Money Market Master Series and $719,512 for Prime Master Series,
    respectively. Effective December 18, 2006, each Master Series pays
    Management a fee at the annual rate of 0.08% of its average daily net
    assets.

    Management and LBAM, the sub-adviser to the Master Series, are wholly-owned
    subsidiaries of Lehman Brothers Holdings Inc., a publicly-owned holding
    company. LBAM is retained by Management to provide day-to-day investment
    management services. LBAM, as sub-adviser to each Master Series, receives a
    monthly fee paid by Management, based on an annual rate of each Master
    Series' average daily net assets. The Master Series do not pay a fee
    directly to LBAM for such services. As investment adviser, Management is
    responsible for overseeing the investment activities of LBAM. Several
    individuals who are officers and/or Trustees of the Trust are also
    employees of LBAM and/or Management.

    Each Master Series has an expense offset arrangement in connection with its
    custodian contract. For the year ended March 31, 2007, the impact of this
    arrangement was a reduction of expenses of $36,060, $38,957, $725, and
    $1,269 for Money Market Master Series, Prime Master Series, Government
    Master Series and Treasury Master Series, respectively.

Note C--Securities Transactions:

    All securities transactions for Money Market Master Series, Prime Master
    Series, Government Master Series, and Treasury Master Series were
    short-term.

Note D--Recent Accounting Pronouncement:

    In September 2006, FASB issued FASB Statement No. 157, "Fair Value
    Measurement" ("SFAS 157"), which defines fair value, establishes a
    framework for measuring fair value, and expands disclosures about fair
    value measurements. SFAS 157 is effective for fiscal years beginning after
    November 15, 2007, and interim periods within those fiscal years.
    Management believes the adoption of SFAS 157 will not have a material
    impact on the Master Series' financial position or results of operations.

Report of Independent Registered Public Accounting Firm


To the Board of Trustees of Institutional Liquidity Trust
and Owners of Beneficial Interest of Money Market Master Series:

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Money Market Master Series (formerly,
Institutional Liquidity Portfolio) (one of the series constituting
Institutional Liquidity Trust) (the "Master Series"), as of March 31, 2007, and
the related statement of operations for the year then ended, the statements of
changes in net assets for each of the two years in the period then ended and
the financial highlights for each of the periods indicated therein. These
financial statements and financial highlights are the responsibility of the
Master Series' 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 audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. We were not engaged to perform an audit of the Master Series'
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 Series' 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 and financial highlights, assessing
the accounting principles used and significant estimates made by management,
and evaluating the overall financial statement presentation. Our procedures
included confirmation of securities owned as of March 31, 2007, by
correspondence with the custodian and brokers. 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 Money
Market Master Series, a portfolio of Institutional Liquidity Trust, at
March 31, 2007, the results of its operations for the year then ended, the
changes in its net assets for each of the two years in the period then ended
and the financial highlights for each of the periods indicated therein, in
conformity with U.S. generally accepted accounting principles.

Board Consideration of the Management and Sub-Advisory Agreements

At a meeting held on September 27, 2006, the Board of Trustees of Institutional
Liquidity Trust ("Board"), including the Trustees who are not "interested
persons" of Neuberger Berman Management Inc. ("Management") (including its
affiliates) or Institutional Liquidity Trust ("Independent Fund Trustees"),
approved the Management and Sub-Advisory Agreements ("Agreements") between
Management and Institutional Liquidity Trust, on behalf of Money Market Master
Series, Prime Master Series, Government Master Series and Treasury Master
Series (each, a "Master Series"). Each of Money Market Portfolio, Prime
Portfolio, Government Portfolio and Treasury Portfolio (each, a "Feeder
Portfolio") invests all of its net investable assets in Money Market Master
Series, Prime Master Series, Government Master Series and Treasury Master
Series, respectively. The term "Fund" is used throughout this section to refer
to each Feeder Portfolio or its corresponding Master Series, as appropriate.

In evaluating the Agreements, the Board, including the Independent Fund
Trustees, reviewed materials furnished by Management and Lehman Brothers Asset
Management Inc. ("Lehman Brothers Asset Management") and met with senior
representatives of Management and Lehman Brothers Asset Management regarding
their personnel and operations. The Independent Fund Trustees were advised by
counsel that is experienced in Investment Company Act of 1940 matters and that
is independent of Management and Lehman Brothers Asset Management.

The Board considered the following factors, among others, in connection with
its approval of the Agreements: (1) the nature, extent, and quality of the
services to be provided by Management and Lehman Brothers Asset Management;
(2) the performance of similar funds managed by Management; (3) the costs of
the services to be provided; (4) the extent to which economies of scale might
be realized as each Fund grows; and (5) whether fee levels reflect those
potential economies of scale for the benefit of investors in each Fund. In
their deliberations, the Board members did not identify any particular
information that was all-important or controlling, and each Trustee may have
attributed different weights to the various factors.

The Board evaluated the terms of the Agreements, the overall fairness of the
Agreements to each Fund and whether the Agreements were in the best interests
of each Fund and its shareholders.

With respect to the nature, extent and quality of the services provided, the
Board considered the performance of similar funds managed by Management and the
degree of risk likely to be undertaken by each Fund's portfolio managers. The
Board considered the experience and staffing of portfolio management and the
investment research personnel of Management and Lehman Brothers Asset
Management that would be dedicated to performing services for the Funds. The
Board noted that Management also would provide certain administrative services,
including fund accounting and compliance oversight. In addition, the Board
noted the positive compliance history of Management, as the firm has been free
of significant compliance problems.

                                      80


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

With respect to the performance of Money Market Portfolio and Prime Portfolio,
the Board considered the performance of Neuberger Berman Institutional Cash
Fund and Cash Management Prime Portfolio, respectively, relative to each Fund's
benchmark and a peer group of investment companies pursuing broadly similar
strategies as each Fund. Neuberger Berman Institutional Cash Fund and Cash
Management Prime Portfolio invest in the same Master Series as Money Market
Portfolio and Prime Portfolio, respectively. The Board also considered the
previous performance of Management in managing Neuberger Berman Institutional
Cash Fund, a series of Neuberger Berman Income Funds and the predecessor to
Neuberger Berman Institutional Cash Fund.

With respect to the performance of Government Portfolio and Treasury Portfolio,
the Board considered the performance of similar funds managed by Management
relative to a peer group of investment companies pursuing broadly similar
strategies as each Fund.

With respect to the overall fairness of the Agreements, the Board considered
the fee structure of each Fund's Agreement as compared to a peer group of
comparable funds and any fall-out benefits likely to accrue to Management or
Lehman Brothers Asset Management or their affiliates.

The Board reviewed a comparison of each Fund's management fee and overall
expense ratio to a peer group of comparable funds. In addition, the Board
considered the contractual limits on Fund expenses undertaken by Management for
the Funds.

The Board considered whether there were other funds that were advised or
sub-advised by Management or its affiliates or separate accounts managed by
Management or its affiliates with similar investment objectives, policies and
strategies as the Funds. The Board compared the fees charged to any comparable
separate accounts to the fees charged to the Funds at various asset levels. The
Board considered the appropriateness and reasonableness of any differences
between the fees charged between each Fund and the comparable separate accounts
and determined that any differences in fees were consistent with the management
and other services provided.

The Board also evaluated any anticipated economies of scale in relation to the
services Management provides to each Fund. The Board considered the relatively
low level of the management fee and the contractual expense limit for each
class of each Fund.

Conclusions

In approving the Agreements, the Board concluded that the terms of each
Agreement are fair and reasonable and that approval of the Agreements is in the
best interest of each Fund and its shareholders. In reaching this
determination, the Board considered that Management and Lehman Brothers Asset
Management could be expected to provide a high level of service to each Fund;
that each Fund's fee structure appeared to the Board to be reasonable given the
nature and quality of services expected to be provided; and that the expected
benefits accruing to Management and its affiliates by virtue of their
relationship to the Funds were reasonable in comparison with the expected costs
of providing the investment advisory services and the expected benefits
accruing to each Fund.
