Performance data quoted represent past performance, which is no guarantee of
future results, and current performance may be lower or higher than the figures
shown. Performance assumes that all dividends and distributions, if any, were
reinvested. For the most recent month-end performance figures, please visit
www.morganstanley.com/im. Investment return and principal value will fluctuate
causing portfolio shares, when redeemed, to be worth more or less than their
original cost. Total returns do not reflect the deduction of taxes that a
shareholder would pay on portfolio distributions or the redemption of portfolio
shares.

Investments in the Money Market, Prime, Government, Treasury and Tax-Exempt
Portfolios (the "Portfolios") are neither insured nor guaranteed by the Federal
Deposit Insurance Corporation. Although the Portfolios seek to preserve the
value of your investment at $1.00 per share, it is possible to lose money by
investing in these Portfolios. Please read the MSILF's prospectuses carefully
before you invest or send money.

Yield quotation more closely reflect the current earnings of the Portfolios than
the total return. As with all money market portfolios, yields will fluctuate as
market conditions change and the seven-day yields are not necessarily indicative
of future performance.

Sincerely,


/s/ Ronald E. Robison

2004 ANNUAL REPORT

October 31, 2004

INVESTMENT OVERVIEW

MONEY MARKET PORTFOLIO

The Money Market Portfolio seeks preservation of capital, daily liquidity and
maximum current income. The Portfolio seeks to maintain a stable net asset value
of $1.00 per share by investing in liquid, high quality U.S. dollar denominated
money market instruments of U.S. and foreign financial and non-financial
corporations.

PERFORMANCE

From the Portfolio's launch date of February 2 through the fiscal year ended
October 31, 2004, the Portfolio's Institutional Share Class had a total return
of 0.95% compared to 0.85% for the Lipper U.S. Institutional Money Market
Average. For the seven-day period ended October 31, 2004, the Portfolio's
Institutional Share Class provided an annualized current yield of 1.75%, while
its 30-day annualized moving average yield was 1.73%.

FACTORS AFFECTING PERFORMANCE

Since the Portfolio's launch date through the end of its fiscal year ended
October 31, the Federal Open Market Committee ("FOMC") raised its federal funds
target rate by 25 basis points on each of three separate occasions: June 30,
August 10, and September 21. At the September 21 FOMC meeting, the Fed stated
that future increases in its federal funds target rate would continue to be at a
"measured pace." The FOMC's formal risk assessment for economic growth and price
stability remained balanced. As of the end of October, the federal funds target
rate stood at 1.75%.

The Portfolio was launched during the first quarter of 2004. At the onset, the
market was characterized by a very flat money market yield curve, with the fed
funds target rate set at a historically low level of 1.00%. During the second
quarter, the economy began to show signs of expansion, and the market began to
anticipate the end of a very easy monetary policy from the Fed. On June 30, the
FOMC decided to embark on its tightening cycle, raising the overnight lending
rate to 1.25%. During the third quarter, preliminary numbers showed that gross
domestic product ("GDP") expanded at an estimated 3.9%, up slightly from 3.3% in
the second quarter, and 4.5% in the first quarter of 2004. October's
unemployment rate was 5.5%, up 0.1% from September. Non-farm payrolls rose
337,000 during October, more than double the trailing-year average of +152,000
per month. Stronger-than-expected October non-farm payrolls combined with
higher-than-forecast inflation for the same month caused money market rates to
increase slightly in anticipation of continued action by the Fed to bring
monetary policy to a neutral posture.

MANAGEMENT STRATEGY

As of October 31, 2004, the Portfolio had net assets of $3.1 billion and a
weighted average maturity ("WAM") of 42 days. Since launching the Portfolio in
early 2004, we have primarily followed a strategy of keeping our WAM on the
short side, concentrating on investments maturing near the next FOMC meeting
date in order to capitalize on higher expected money market interest rates. This
has primarily been achieved by investing in short, 30-day commercial paper and
certificates of deposit ("CDs"). In order to diversify the maturity structure of
the Portfolio and take advantage of steepness in the money market yield curve,
we have also selectively added six-month asset-backed commercial paper as the
market fully priced in future tightening moves by the FOMC. In addition, we have
looked to increase our exposure to floating rate notes, favoring one-month
Libor-based indices, while also selectively purchasing three-month Libor-based
floaters.

EXPENSE EXAMPLE

As a shareholder of the Portfolio, you incur ongoing costs, including management
fees and other Portfolio expenses. This example is intended to help you
understand your ongoing costs (in dollars) of investing in the Portfolio and to
compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the
six-month period ended October 31, 2004 and held for the entire six-month
period.

ACTUAL EXPENSES

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that 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 line under the heading entitled "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual expense
ratio and an assumed rate of return of 5% per year before expenses, which 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 the Portfolio and other funds. To do so, compare this 5%

2004 ANNUAL REPORT

October 31, 2004

INVESTMENT OVERVIEW

PRIME PORTFOLIO

The Prime Portfolio seeks preservation of capital, daily liquidity and maximum
current income. The Portfolio seeks to maintain a stable net asset value of
$1.00 per share by investing in liquid, high quality money market instruments of
domestic financial and non-financial corporations, as well as obligations of the
U.S. government and its agencies and instrumentalities.

PERFORMANCE

From the Portfolio's launch date of February 2 through the fiscal year ended
October 31, 2004, the Portfolio's Institutional Share Class had a total return
of 0.94% compared to 0.85% for the Lipper U.S. Institutional Money Market
Average. For the seven-day period ended October 31, 2004, the Portfolio's
Institutional Share Class provided an annualized current yield of 1.75%, while
its 30-day annualized moving average yield was 1.73%.

FACTORS AFFECTING PERFORMANCE

Since the Portfolio's launch date through the end of its fiscal year ended
October 31, the Federal Open Market Committee ("FOMC") raised its federal funds
target rate by 25 basis points on each of three separate occasions: June 30,
August 10, and September 21. At the September 21 FOMC meeting, the Fed stated
that future increases in its federal funds target rate would continue to be at a
"measured pace." The FOMC's formal risk assessment for economic growth and price
stability remained balanced. As of the end of October, the federal funds target
rate stood at 1.75%.

The Portfolio was launched during the first quarter of 2004. At the onset, the
market was characterized by a very flat money market yield curve, with the fed
funds target rate set at a historically low level of 1.00%. During the second
quarter, the economy began to show signs of expansion, and the market began to
anticipate the end of a very easy monetary policy from the Fed. On June 30, the
FOMC decided to embark on its tightening cycle, raising the overnight lending
rate to 1.25%. During the third quarter, the gross domestic product ("GDP")
expanded at an estimated 3.9%, up slightly from 3.3% in the second quarter, and
4.5% in the first quarter of 2004. October's unemployment rate was 5.5%, up 0.1%
from September. Non-farm payrolls rose 337,000 during October, more than double
the trailing-year average of +152,000 per month. Stronger-than-expected October
non-farm payrolls combined with higher-than-forecast inflation for the same
month caused money market rates to increase slightly in anticipation of
continued action by the Fed to bring monetary policy to a neutral posture.

MANAGEMENT STRATEGY

As of October 31, 2004, the Portfolio had net assets of $8.7 billion and a
weighted average maturity ("WAM") of 33 days. Since launching the Portfolio in
early 2004, we have primarily followed a strategy of keeping our WAM on the
short side, concentrating on investments maturing near the next FOMC meeting
date in order to capitalize on higher expected money market interest rates. This
has primarily been achieved by investing in short, 30-day commercial paper and
certificates of deposit ("CDs"). In order to diversify the maturity structure of
the Portfolio and take advantage of steepness in the money market yield curve,
we have also selectively added six-month asset-backed commercial paper as the
market fully priced in future tightening moves by the FOMC. In addition, we have
looked to increase the Portfolio's exposure to floating rate notes, favoring
one-month Libor-based indices.

EXPENSE EXAMPLE

As a shareholder of the Portfolio, you incur ongoing costs, including management
fees and other Portfolio expenses. This example is intended to help you
understand your ongoing costs (in dollars) of investing in the Portfolio and to
compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the
six-month period ended October 31, 2004 and held for the entire six-month
period.

ACTUAL EXPENSES

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that 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 line under the heading entitled "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual expense
ratio and an assumed rate of return of 5% per year before expenses, which 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 the Portfolio and other funds. To do so, compare this 5%

                                                        2004 ANNUAL REPORT

                                                        October 31, 2004

INVESTMENT OVERVIEW

GOVERNMENT PORTFOLIO

The Government Portfolio seeks preservation of capital, daily liquidity and
maximum current income. The Portfolio seeks to maintain a stable net asset value
of $1.00 per share by investing exclusively in obligations of the U.S.
government and its agencies and instrumentalities and in repurchase agreements
collateralized by such securities.

PERFORMANCE

From the Portfolio's launch date of August 9 through the fiscal year ended
October 31, 2004, the Portfolio's Institutional Share Class had a total return
of 0.38% compared to 0.32% for the Lipper Institutional U.S. Government Money
Market Fund Index. For the seven-day period ended October 31, 2004, the
Portfolio's Institutional Share Class provided an annualized current yield of
1.80%, while its annualized 30-day moving average yield was 1.78%.

FACTORS AFFECTING PERFORMANCE

Since the Portfolio's launch date through the end of its fiscal year ended
October 31, the Federal Open Market Committee ("FOMC") raised its federal funds
target rate on two separate occasions, August 10 and September 21, by 25 basis
points each time. At the September 21 FOMC meeting, the Fed stated that future
increases in its federal funds target rate would continue to be at a "measured
pace." The FOMC's formal risk assessment for economic growth and price stability
remained balanced. As of the end of October, the federal funds target rate stood
at 1.75%.

The Portfolio was launched during the third quarter of 2004. During the third
quarter, preliminary numbers showed that gross domestic product ("GDP") expanded
at an estimated 3.9%, up slightly from 3.3% in the second quarter, and 4.5% in
the first quarter of 2004. October's unemployment rate was 5.5%, up 0.1% from
September. Non-farm payrolls rose 337,000 during October, more than double the
trailing-year average of +152,000 per month. Stronger-than-expected October
non-farm payrolls combined with higher-than-forecast inflation for the same
month caused money market rates to increase slightly in anticipation of
continued action by the Fed to bring monetary policy to a neutral posture.

MANAGEMENT STRATEGY

As of October 31, 2004, the Portfolio had net assets of $548.1 million and a
weighted average maturity ("WAM") of 17 days. As of the end of October,
approximately 61% of the Portfolio was invested in overnight and term repurchase
agreements, 22% in floating rate Federal agency obligations, and 17% in fixed
rate Federal agency obligations.

Since launching the Portfolio in early August 2004, we have primarily followed a
strategy of concentrating our investments in fixed rate securities that mature,
or floating rate notes that reset, near the next FOMC meeting date in order to
capitalize on higher expected money market interest rates. This has primarily
been achieved by investing in overnight and term repurchase agreements,
one-month Federal agency discount notes, and floating rate notes that reset on
either a daily or a monthly basis. In order to diversify the maturity structure
of the Portfolio and to take advantage of the steepness in the money market
yield curve, we have also selectively added several positions in discount notes
or debentures in the six-month or longer portion of the money market curve.

EXPENSE EXAMPLE

As a shareholder of the Portfolio, you incur ongoing costs, including management
fees and other Portfolio expenses. This example is intended to help you
understand your ongoing costs (in dollars) of investing in the Portfolio and to
compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested from August 9, 2004 to
October 31, 2004 for the Institutional and Investor Classes and October 1, 2004
to October 31, 2004 for the Advisory Class and held for the entire period.

ACTUAL EXPENSES

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that 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 line under the heading entitled "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual expense
ratio and an assumed rate of return of 5% per year before expenses, which 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 the Portfolio and other funds. To do so, compare this 5%
hypothetical example with the 5% hypothetical examples that appear in the
shareholder reports of the other funds.

                                                                              13

2004 ANNUAL REPORT

October 31, 2004

INVESTMENT OVERVIEW

TREASURY PORTFOLIO

The Treasury Portfolio seeks preservation of capital, daily liquidity and
maximum current income. The Portfolio seeks to maintain a stable net asset value
of $1.00 per share by investing exclusively in U.S. Treasury obligations and
repurchase agreements collateralized by such securities.

PERFORMANCE

From the Portfolio's launch date of August 9 through the fiscal year ended
October 31, 2004, the Portfolio's Institutional Share Class had a total return
of 0.36% compared to 0.36% for the Lipper Institutional U.S. Treasury Money
Market Fund Index. For the seven-day period ended October 31, 2004, the
Portfolio's Institutional Share Class provided an annualized current yield of
1.72%, while its annualized 30-day moving average yield was 1.70%.

FACTORS AFFECTING PERFORMANCE

Since the Portfolio's launch date through the end of its fiscal year ended
October 31, the Federal Open Market Committee ("FOMC") raised its federal funds
target rate on two separate occasions, August 10 and September 21, by 25 basis
points each time. At the September 21 FOMC meeting, the Fed stated that future
increases in its federal funds target rate would continue to be at a "measured
pace." The FOMC's formal risk assessment for economic growth and price stability
remained balanced. As of the end of October, the federal funds target rate stood
at 1.75%.

The Portfolio was launched during the third quarter of 2004. During the third
quarter, preliminary numbers showed that gross domestic product ("GDP") expanded
at an estimated 3.9%, up slightly from 3.3% in the second quarter, and 4.5% in
the first quarter of 2004. October's unemployment rate was 5.5%, up 0.1% from
September. Non-farm payrolls rose 337,000 during October, more than double the
trailing-year average of +152,000 per month. Stronger-than-expected October
non-farm payrolls combined with higher-than-forecast inflation for the same
month caused money market rates to increase slightly in anticipation of
continued action by the Fed to bring monetary policy to a neutral posture.

MANAGEMENT STRATEGY

As of October 31, 2004, the Portfolio had net assets of $190.0 million and a
weighted average maturity of 17 days. As of the end of October, approximately
85% of the Portfolio was invested in overnight and term repurchase agreements,
14% in Treasury bills, and 1% in a Treasury note.

Since launching the Portfolio in early August 2004, we have primarily followed a
strategy of concentrating investments maturing near the next FOMC meeting date
in order to capitalize on higher expected money market interest rates. This has
primarily been achieved by investing in overnight and term repurchase agreements
backed by Treasury collateral. In order to diversify the maturity structure of
the Portfolio and take advantage of steepness in the money market yield curve,
we have also selectively added several positions in six-month Treasury bills and
a ten-month Treasury note.

EXPENSE EXAMPLE

As a shareholder of the Portfolio, you incur ongoing costs, including management
fees and other Portfolio expenses. This example is intended to help you
understand your ongoing costs (in dollars) of investing in the Portfolio and to
compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested from August 9, 2004 to
October 31, 2004 and held for the entire period.

ACTUAL EXPENSES

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that 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 line under the heading entitled "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual expense
ratio and an assumed rate of return of 5% per year before expenses, which 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 the Portfolio and other funds. To do so, compare this 5%
hypothetical example with the 5% hypothetical examples that appear in the
shareholder reports of the other funds.

                                                        2004 ANNUAL REPORT

                                                        October 31, 2004

INVESTMENT OVERVIEW

TAX-EXEMPT PORTFOLIO

The Tax-Exempt Portfolio seeks to maximize current income exempt from federal
income tax to the extent consistent with preservation of capital and maintenance
of liquidity. The Portfolio seeks to maintain a stable net asset value of $1.00
per share by investing at least 80% of its assets in high quality short-term
municipal obligations, the interest of which is exempt from federal income taxes
and is not subject to the federal alternative minimum tax.

PERFORMANCE

From the Portfolio's launch date of February 2 through the fiscal year ended
October 31, 2004, the Portfolio's Institutional Share Class had a total return
of 0.84% compared to 0.67% for the Lipper Institutional Tax-Exempt Money Market
Fund Average. For the seven-day period ended October 31, 2004, the Portfolio's
Institutional Share Class provided an annualized current yield of 1.65%, while
its 30-day annualized moving average yield was 1.59%.

FACTORS AFFECTING PERFORMANCE

Tax-free money market yields remained relatively stable during the first half of
2004, which was in line with prevailing monetary policy.

Beginning in June, four consecutive increases to the Federal Funds target rate
and the anticipation of more have pushed short-term tax-exempt yields to their
highest levels in two years. This has also produced a flat yield curve
relationship between variable rate securities and one-year fixed rate
instruments.

Demand for tax-exempt money market instruments remains strong as investors seek
to preserve capital in a rising interest rate environment.

MANAGEMENT STRATEGY

Since launching the Portfolio in early 2004, we have maintained an emphasis on
variable rate securities. Among fixed-rate instruments, we have sought to
maintain a laddered maturity structure providing some of the benefits of the
more positive slope of the money market yield curve while limiting the risks
associated with longer maturity paper.

We remain cautious in managing the Portfolio's average maturity, preferring to
avoid the one-year segment of the money market in anticipation of further
increases in yields.

EXPENSE EXAMPLE

As a shareholder of the Portfolio, you incur ongoing costs, including management
fees and other Portfolio expenses. This example is intended to help you
understand your ongoing costs (in dollars) of investing in the Portfolio and to
compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested from May 1, 2004 to
October 31, 2004 for the Institutional Class, June 8, 2004 to October 31, 2004
for the Investor Class and June 15, 2004 to October 31, 2004 for the Advisory
Class and held for the entire period.

ACTUAL EXPENSES

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that 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 line under the heading entitled "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Portfolio's actual expense
ratio and an assumed rate of return of 5% per year before expenses, which 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 the Portfolio and other funds. To do so, compare this 5%
hypothetical example with the 5% hypothetical examples that appear in the
shareholder reports of the other funds.

                                                        2004 ANNUAL REPORT

                                                        October 31, 2004

NOTES TO FINANCIAL STATEMENTS

Morgan Stanley Institutional Liquidity Funds (the "Fund") is registered under
the Investment Company Act of 1940 (the "1940 Act"), as amended, as a
Massachusetts business trust. The Fund is comprised of five separate, active,
diversified portfolios (individually referred to as a "Portfolio", collectively
as the "Portfolios"). Each Portfolio currently offers three classes of shares -
Institutional Class, Investor Class and Advisory Class. All classes of shares
have identical voting rights (except that shareholders of a Class have exclusive
voting rights regarding any matter relating solely to that Class of shares),
dividend, liquidation and other rights.

For detailed descriptions of the investment objectives of each of the Portfolios
and other related information, please refer to the Prospectuses of the Fund.
Generally, the investment objective of the Portfolios is to seek preservation of
capital, daily liquidity and maximum current income (exempt from federal income
tax in the case of Tax-Exempt Portfolio).

A. ACCOUNTING POLICIES: The following significant accounting policies are in
conformity with U.S. generally accepted accounting principles for investment
companies. Such policies are consistently followed by the Fund in the
preparation of the financial statements.  U.S. generally accepted accounting
principles may require management to make estimates and assumptions that
affect the reported amounts and disclosures in the financial statements.
Actual results may differ from those estimates.

1.  SECURITY VALUATION: Securities owned by the Portfolios are stated at
    amortized cost which approximates market value.

2.  REPURCHASE AGREEMENTS: Certain Portfolios may enter into repurchase
    agreements under which a Portfolio lends excess cash and takes possession of
    securities with an agreement that the counterparty will repurchase such
    securities. In connection with transactions in repurchase agreements, a bank
    as custodian for the Fund takes possession of the underlying securities
    which are held as collateral, with a market value at least equal to the
    amount of the repurchase transaction, including principal and accrued
    interest. To the extent that any repurchase transaction exceeds one business
    day, the value of the collateral is marked-to-market on a daily basis to
    determine the adequacy of the collateral. In the event of default on the
    obligation to repurchase, the Fund has the right to liquidate the collateral
    and apply the proceeds in satisfaction of the obligation. In the event of
    default or bankruptcy by the counterparty to the agreement, realization
    and/or retention of the collateral or proceeds may be subject to legal
    proceedings. The Portfolios, along with other affiliated investment
    companies, may utilize a joint trading account for the purpose of entering
    into repurchase agreements.

3.  OTHER: Security transactions are accounted for on the date the securities
    are purchased or sold. Realized gains and losses on the sale of investment
    securities are determined on a "first-in-first-out" basis. Interest income
    is recognized on the accrual basis except where collection is in doubt.
    Discounts and premiums on securities purchased are amortized over their
    respective lives. Most expenses of the Fund can be directly attributed to a
    particular Portfolio. Expenses which cannot be directly attributed are
    apportioned among the Portfolios based upon relative net assets. Income,
    expenses (other than class specific expenses) and realized and unrealized
    gains or losses are allocated to each class of shares based upon their
    relative net assets. Dividends to the shareholders of the Portfolios are
    accrued daily and are distributed on the last business day of each month.

B. INVESTMENT ADVISORY FEES: Morgan Stanley Investment Management, Inc. (the
"Adviser" or "MSIM"), a wholly-owned subsidiary of Morgan Stanley, provides the
Fund with investment advisory services under the terms of an Investment Advisory
and Management Agreement (the "Agreement") at the annual rates of average daily
net assets indicated below. The Adviser has voluntarily agreed to reduce its
advisory fee and/or absorb other expenses so that the total operating expenses
of each share class will not exceed the amounts noted below in the first year of
operations. After the first year of operations, this fee and expense waiver may
be discontinued at any time.

</Table>

The Ratio of Expenses to Average Net Assets disclosed in the Portfolios'
Financial Highlights may be lower than the maximum ratios indicated in the table
above due to additional voluntary expense limitations imposed by the Adviser.
The Adviser may terminate these additional voluntary limitations at any time at
its sole discretion.

The Adviser has entered into a Sub-Advisory Agreement with Morgan Stanley
Investment Advisors Inc. (the "Sub-Adviser"), a wholly-owned subsidiary of
Morgan Stanley. The Sub-Adviser, subject to the control and supervision of the
Fund, its officers, Trustees and the Adviser, and in accordance with the
investment objectives, policies and restrictions of the Portfolios, makes
day-to-day investment decisions for the Portfolios and places the Portfolios'
purchase and sales orders. The Adviser pays the Sub-Adviser on a monthly basis a
portion of the net advisory fees the Adviser receives from the Portfolios.

C. ADMINISTRATOR: MSIM (the "Administrator") serves as Administrator to the Fund
pursuant to an Administration Agreement. Under the agreement, MSIM receives an
annual fee, accrued daily and payable monthly, of 0.05% of each Portfolio's
average daily net assets, plus reimbursement of out-of-pocket expenses. J.P.
Morgan Investor Services Co. ("JPMIS"), a corporate affiliate of JPMorgan Chase
Bank, provides fund accounting and other services pursuant to a
sub-administration agreement with MSIM and receives compensation for these
services. JPMIS also serves as the Transfer Agent to the Fund pursuant to a
Transfer Agency Agreement. An employee of JPMIS is an officer of the Fund.

D. DISTRIBUTION AND SERVICE AND SHAREHOLDER ADMINISTRATION FEES: Morgan Stanley
& Co. Incorporated (the "Distributor"), a wholly-owned subsidiary of Morgan
Stanley, and an affiliate of

                                                                              29

Assets due to short-term capital gains being treated as ordinary income for
tax purposes. The tax character of distributions paid during fiscal 2004 were

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

TO THE SHAREHOLDERS AND BOARD OF TRUSTEES OF
MORGAN STANLEY INSTITUTIONAL LIQUIDITY FUNDS

We have audited the accompanying statements of assets and liabilities, including
the portfolios of investments, of the Money Market Portfolio, Prime Portfolio,
Government Portfolio, Treasury Portfolio and Tax-Exempt Portfolio (the "Funds")
(the five portfolios constituting Morgan Stanley Institutional Liquidity Funds)
as of October 31, 2004, and the related statements of operations, statements of
changes in net assets and the financial highlights for each of the periods
indicated therein. These financial statements and financial highlights are the
responsibility of the Funds' 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. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements and financial highlights. Our procedures
included confirmation of securities owned as of October 31, 2004 by
correspondence with the custodian and brokers or by other appropriate auditing
procedures where replies from brokers were not received. 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 each
of the portfolios constituting Morgan Stanley Institutional Liquidity Funds at
October 31, 2004, the results of their operations, the changes in their net
assets and the financial highlights for each of the periods indicated therein,
in conformity with U.S. generally accepted accounting principles.

(a)  The Fund has adopted a code of ethics (the "Code of Ethics") that applies
to its principal executive officer, principal financial officer, principal
accounting officer or controller, or persons performing similar functions,
regardless of whether these individuals are employed by the Fund or a third
party.

shareholder report presented in Item 1 hereto to delete from the end of the
following paragraph on page 2 of the Code the phrase "to the detriment of the
Fund.":

"Each Covered Officer must not use his personal influence or personal
relationship improperly to influence investment decisions or financial reporting
by the Fund whereby the Covered Officer would benefit personally (directly or

Item 3. Audit Committee Financial Expert.

The Fund's Board of Directors has determined that it has two "audit committee
financial experts" serving on its audit committee, each of whom are
"independent" Directors: Dr. Manuel H. Johnson and Joseph J. Kearns. Under
applicable securities laws, a person who is determined to be an audit committee
financial expert will not be deemed an "expert" for any purpose, including
without limitation for the purposes of Section 11 of the Securities Act of 1933,
as a result of being designated or identified as an audit committee financial
expert. The designation or identification of a person as an audit committee
financial expert does not impose on such person any duties, obligations, or
liabilities that are greater than the duties, obligations, and liabilities
imposed on such person as a member of the audit committee and Board of Directors
in the absence of such designation or identification.

                                 AUDIT COMMITTEE
                          AUDIT AND NON-AUDIT SERVICES
                       PRE-APPROVAL POLICY AND PROCEDURES
                                     OF THE
                  MORGAN STANLEY RETAIL AND INSTITUTIONAL FUNDS
                    AS ADOPTED AND AMENDED JULY 23, 2004,(1)

- -    Statement of Principles

The Audit Committee of the Board is required to review and, in its sole
discretion, pre-approve all Covered Services to be provided by the Independent
Auditors to the Fund and Covered Entities in order to assure that services
performed by the Independent Auditors do not impair the auditor's independence
from the Fund.

The SEC has issued rules specifying the types of services that an independent
auditor may not provide to its audit client, as well as the audit committee's
administration of the engagement of the independent auditor. The SEC's rules
establish two different approaches to pre-approving services, which the SEC
considers to be equally valid. Proposed services either: may be pre-approved
without consideration of specific case-by-case services by the Audit Committee
("GENERAL PRE-APPROVAL"); or require the specific pre-approval of the Audit
Committee or its delegate ("SPECIFIC PRE-APPROVAL"). The Audit Committee
believes that the combination of these two approaches in this Policy will result
in an effective and efficient procedure to pre-approve services performed by the
Independent Auditors. As set forth in this Policy, unless a type of service has
received general pre-approval, it will require specific pre-approval by the
Audit Committee (or by any member of the Audit Committee to which pre-approval
authority has been delegated) if it is to be provided by the Independent
Auditors. Any proposed services exceeding pre-approved cost levels or budgeted
amounts will also require specific pre-approval by the Audit Committee.

The appendices to this Policy describe the Audit, Audit-related, Tax and All
Other services that have the general pre-approval of the Audit Committee. The
term of any general pre-approval is 12 months from the date of pre-approval,
unless the Audit Committee considers and provides a different period and states
otherwise. The Audit Committee will annually review and pre-approve the services
that may be provided by the Independent Auditors without obtaining specific
pre-approval from the Audit Committee. The Audit Committee will add to or
subtract from the list of general pre-approved services from time to time, based
on subsequent determinations.

- ----------
(1)  This Audit Committee Audit and Non-Audit Services Pre-Approval Policy and
     Procedures (the "POLICY"), adopted as of the date above, supersedes and
     replaces all prior versions that may have been adopted from time to time.

<Page>

The purpose of this Policy is to set forth the policy and procedures by which
the Audit Committee intends to fulfill its responsibilities. It does not
delegate the Audit Committee's responsibilities to pre-approve services
performed by the Independent Auditors to management.

The Fund's Independent Auditors have reviewed this Policy and believes that
implementation of the Policy will not adversely affect the Independent Auditors'
independence. - Delegation As provided in the Act and the SEC's rules, the Audit
Committee may delegate either type of pre-approval authority to one or more of
its members. The member to whom such authority is delegated must report, for
informational purposes only, any pre-approval decisions to the Audit Committee
at its next scheduled meeting.

- -    Audit Services

The annual Audit services engagement terms and fees are subject to the specific
pre-approval of the Audit Committee. Audit services include the annual financial
statement audit and other procedures required to be performed by the Independent
Auditors to be able to form an opinion on the Fund's financial statements. These
other procedures include information systems and procedural reviews and testing
performed in order to understand and place reliance on the systems of internal
control, and consultations relating to the audit. The Audit Committee will
approve, if necessary, any changes in terms, conditions and fees resulting from
changes in audit scope, Fund structure or other items.

In addition to the annual Audit services engagement approved by the Audit
Committee, the Audit Committee may grant general pre-approval to other Audit
services, which are those services that only the Independent Auditors reasonably
can provide. Other Audit services may include statutory audits and services
associated with SEC registration statements (on Forms N-1A, N-2, N-3, N-4,
etc.), periodic reports and other documents filed with the SEC or other
documents issued in connection with securities offerings.

The Audit Committee has pre-approved the Audit services in Appendix B.1. All
other Audit services not listed in Appendix B.1 must be specifically
pre-approved by the Audit Committee (or by any member of the Audit Committee to
which pre-approval has been delegated).

- -    Audit-related Services

Audit-related services are assurance and related services that are reasonably
related to the performance of the audit or review of the Fund's financial
statements and, to the extent they are Covered Services, the Covered Entities or
that are traditionally performed by the Independent Auditors. Because the Audit
Committee believes that the provision of Audit-related services does not impair
the independence of the auditor and is consistent with the SEC's rules on
auditor independence, the Audit Committee may grant general pre-approval to
Audit-related services. Audit-related services include, among others, accounting
consultations related to accounting, financial reporting or disclosure matters

<Page>

not classified as "Audit services"; assistance with understanding and
implementing new accounting and financial reporting guidance from rulemaking
authorities; agreed-upon or expanded audit procedures related to accounting
and/or billing records required to respond to or comply with financial,
accounting or regulatory reporting matters; and assistance with internal control
reporting requirements under Forms N-SAR and/or N-CSR.

The Audit Committee has pre-approved the Audit-related services in Appendix B.2.
All other Audit-related services not listed in Appendix B.2 must be specifically
pre-approved by the Audit Committee (or by any member of the Audit Committee to
which pre-approval has been delegated).

- -    Tax Services

The Audit Committee believes that the Independent Auditors can provide Tax
services to the Fund and, to the extent they are Covered Services, the Covered
Entities, such as tax compliance, tax planning and tax advice without impairing
the auditor's independence, and the SEC has stated that the Independent Auditors
may provide such services.

Pursuant to the preceding paragraph, the Audit Committee has pre-approved the
Tax Services in Appendix B.3. All Tax services in Appendix B.3 must be
specifically pre-approved by the Audit Committee (or by any member of the Audit
Committee to which pre-approval has been delegated).

- -    All Other Services

The Audit Committee believes, based on the SEC's rules prohibiting the
Independent Auditors from providing specific non-audit services, that other
types of non-audit services are permitted. Accordingly, the Audit Committee
believes it may grant general pre-approval to those permissible non-audit
services classified as All Other services that it believes are routine and
recurring services, would not impair the independence of the auditor and are
consistent with the SEC's rules on auditor independence.

The Audit Committee has pre-approved the All Other services in Appendix B.4.
Permissible All Other services not listed in Appendix B.4 must be specifically
pre-approved by the Audit Committee (or by any member of the Audit Committee to
which pre-approval has been delegated).

- -    Pre-Approval Fee Levels or Budgeted Amounts

Pre-approval fee levels or budgeted amounts for all services to be provided by
the Independent Auditors will be established annually by the Audit Committee.
Any proposed services exceeding these levels or amounts will require specific
pre-approval by the Audit Committee. The Audit Committee is mindful of the
overall relationship of fees for audit and non-audit services in determining
whether to pre-approve any such services.

- -    Procedures

All requests or applications for services to be provided by the Independent
Auditors that do not require specific approval by the Audit Committee will be
submitted to the Fund's Chief Financial Officer and must include a detailed
description of the services to be

<Page>

rendered. The Fund's Chief Financial Officer will determine whether such
services are included within the list of services that have received the general
pre-approval of the Audit Committee. The Audit Committee will be informed on a
timely basis of any such services rendered by the Independent Auditors. Requests
or applications to provide services that require specific approval by the Audit
Committee will be submitted to the Audit Committee by both the Independent
Auditors and the Fund's Chief Financial Officer, and must include a joint
statement as to whether, in their view, the request or application is consistent
with the SEC's rules on auditor independence.

The Audit Committee has designated the Fund's Chief Financial Officer to monitor
the performance of all services provided by the Independent Auditors and to
determine whether such services are in compliance with this Policy. The Fund's
Chief Financial Officer will report to the Audit Committee on a periodic basis
on the results of its monitoring. Both the Fund's Chief Financial Officer and
management will immediately report to the chairman of the Audit Committee any
breach of this Policy that comes to the attention of the Fund's Chief Financial
Officer or any member of management.

- -    Additional Requirements

The Audit Committee has determined to take additional measures on an annual
basis to meet its responsibility to oversee the work of the Independent Auditors
and to assure the auditor's independence from the Fund, such as reviewing a
formal written statement from the Independent Auditors delineating all
relationships between the Independent Auditors and the Fund, consistent with
Independence Standards Board No. 1, and discussing with the Independent Auditors
its methods and procedures for ensuring independence.

- -    Covered Entities

Covered Entities include the Fund's investment adviser(s) and any entity
controlling, controlled by or under common control with the Fund's investment
adviser(s) that provides ongoing services to the Fund(s). Beginning with
non-audit service contracts entered into on or after May 6, 2003, the Fund's
audit committee must pre-approve non-audit services provided not only to the
Fund but also to the Covered Entities if the engagements relate directly to the
operations and financial reporting of the Fund. This list of Covered Entities
would include:
