The MSILF currently offers five portfolios (Money Market, Prime, Government, Treasury and Tax-Exempt), which together are designed to provide flexible cash management options. MSILF's portfolios provide investors with a means to help them meet specific cash investment needs, whether they need a rated fund, capital preservation, or tax-efficient returns. PERFORMANCE The seven-day current and seven-day effective yields (which assume an annualization of the current yield with all dividends reinvested) as of October 31, 2004, were as follows: <Table> <Caption> PORTFOLIO 7-DAY CURRENT YIELD 7-DAY EFFECTIVE YIELD --------- ------------------- --------------------- Money Market -- Institutional Class 1.75% 1.77% Money Market -- Advisory Class 1.50% 1.51% Prime -- Institutional Class 1.75% 1.77% Prime -- Advisory Class 1.50% 1.52% Government -- Institutional Class 1.80% 1.81% Government -- Investor Class 1.70% 1.71% Government -- Advisory Class 1.55% 1.56% Treasury -- Institutional Class 1.72% 1.73% Treasury -- Advisory Class 1.47% 1.48% Tax-Exempt -- Institutional Class 1.65% 1.67% Tax-Exempt -- Investor Class 1.55% 1.57% Tax-Exempt -- Advisory Class 1.41% 1.42% </Table> 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 Ronald E. Robison Executive Vice President -- Principal Executive Officer November 2004 3 <Page> 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% 4 <Page> 2004 ANNUAL REPORT October 31, 2004 INVESTMENT OVERVIEW (CONT'D) MONEY MARKET PORTFOLIO hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. <Table> <Caption> EXPENSES PAID ENDING ACCOUNT DURING PERIOD* BEGINNING VALUE MAY 1, 2004 -- ACCOUNT VALUE OCTOBER 31, OCTOBER 31, MAY 1, 2004 2004 2004 - ------------------------------------------------------------------------------------------------------------------ INSTITUTIONAL CLASS Actual $ 1,000.00 $ 1,006.90 $ 0.40 Hypothetical (5% average annual return before expenses) 1,000.00 1,024.73 0.41 </Table> * Expenses are equal to the Portfolio's annualized net expense ratio of 0.08%, multiplied by the average account value over the period, multiplied by 184/366 (to reflect the one-half year period). <Table> <Caption> EXPENSES PAID ENDING ACCOUNT DURING PERIOD* BEGINNING VALUE MAY 1, 2004 -- ACCOUNT VALUE OCTOBER 31, OCTOBER 31, MAY 1, 2004 2004 2004 - ------------------------------------------------------------------------------------------------------------------ ADVISORY CLASS Actual $ 1,000.00 $ 1,005.70 $ 1.71 Hypothetical (5% average annual return before expenses) 1,000.00 1,023.43 1.73 </Table> * Expenses are equal to the Portfolio's annualized net expense ratio of 0.34%, multiplied by the average account value over the period, multiplied by 184/366 (to reflect the one-half year period).

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% 8 <Page> 2004 ANNUAL REPORT October 31, 2004 INVESTMENT OVERVIEW (CONT'D) PRIME PORTFOLIO hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. <Table> <Caption> EXPENSES PAID ENDING ACCOUNT DURING PERIOD* BEGINNING VALUE MAY 1, 2004 -- ACCOUNT VALUE OCTOBER 31, OCTOBER 31, MAY 1, 2004 2004 2004 - ------------------------------------------------------------------------------------------------------------------ INSTITUTIONAL CLASS Actual $ 1,000.00 $ 1,006.90 $ 0.40 Hypothetical (5% average annual return before expenses) 1,000.00 1,024.73 0.41 </Table> * Expenses are equal to the Portfolio's annualized net expense ratio of 0.08%, multiplied by the average account value over the period, multiplied by 184/366 (to reflect the one-half year period). <Table> <Caption> EXPENSES PAID ENDING ACCOUNT DURING PERIOD* BEGINNING VALUE MAY 1, 2004 -- ACCOUNT VALUE OCTOBER 31, OCTOBER 31, MAY 1, 2004 2004 2004 - ------------------------------------------------------------------------------------------------------------------ ADVISORY CLASS Actual $ 1,000.00 $ 1,005.60 $ 1.66 Hypothetical (5% average annual return before expenses) 1,000.00 1,023.48 1.68 </Table> * Expenses are equal to the Portfolio's annualized net expense ratio of 0.33%, multiplied by the average account value over the period, multiplied by 184/366 (to reflect the one-half year period).

THE ACCOMPANYING NOTES ARE AN INTEGRAL PART OF THE FINANCIAL STATEMENTS. 12 <Page> 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 ACCOMPANYING NOTES ARE AN INTEGRAL PART OF THE FINANCIAL STATEMENTS. 15 <Page> 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. 16 <Page> 2004 ANNUAL REPORT October 31, 2004 INVESTMENT OVERVIEW (CONT'D) TREASURY PORTFOLIO 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. <Table> <Caption> EXPENSES PAID ENDING ACCOUNT DURING PERIOD* BEGINNING VALUE AUGUST 9, 2004 ACCOUNT VALUE OCTOBER 31, -- OCTOBER 31, AUGUST 9, 2004 2004 2004 - ---------------------------------------------------------------------------------------------- INSTITUTIONAL CLASS Actual $ 1,000.00 $ 1,003.60 $ 0.11 Hypothetical (5% average annual return before 1,000.00 1,011.36 0.12 expenses) ADVISORY CLASS Actual 1,000.00 1,003.00 0.69 Hypothetical (5% average annual return before 1,000.00 1,010.79 0.69 expenses) </Table> * Expenses are equal to the Institutional Class' and Advisory Class' annualized net expense ratio of 0.05% and 0.30%, respectively, multiplied by the average account value over the period, multiplied by 84/366 (to reflect the period).

THE ACCOMPANYING NOTES ARE AN INTEGRAL PART OF THE FINANCIAL STATEMENTS. 18 <Page> 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. <Table> <Caption> EXPENSES PAID ENDING ACCOUNT DURING PERIOD* BEGINNING VALUE MAY 1, 2004 -- ACCOUNT VALUE OCTOBER 31, OCTOBER 31, MAY 1, 2004 2004 2004 - ---------------------------------------------------------------------------------------------- INSTITUTIONAL CLASS Actual $ 1,000.00 $ 1,006.00 $ 0.35 Hypothetical (5% average annual return before expenses) 1,000.00 1,024.78 0.36 </Table> * Expenses are equal to the Portfolio's annualized net expense ratio of 0.07%, multiplied by the average account value over the period, multiplied by 184/366 (to reflect the one-half year period). <Table> <Caption> EXPENSES PAID ENDING ACCOUNT DURING PERIOD* BEGINNING VALUE JUNE 8, 2004 -- ACCOUNT VALUE OCTOBER 31, OCTOBER 31, JUNE 8, 2004 2004 2004 - ---------------------------------------------------------------------------------------------- INVESTOR CLASS Actual $ 1,000.00 $ 1,004.50 $ 0.68 Hypothetical (5% average annual return before expenses) 1,000.00 1,019.27 0.68 </Table> * Expenses are equal to the Portfolio's annualized net expense ratio of 0.17%, multiplied by the average account value over the period, multiplied by 146/366 (to reflect the period). 19 <Page> 2004 ANNUAL REPORT October 31, 2004 INVESTMENT OVERVIEW (CONT'D) TAX-EXEMPT PORTFOLIO <Table> <Caption> EXPENSES PAID BEGINNING ENDING ACCOUNT DURING PERIOD* ACCOUNT VALUE VALUE JUNE 15, 2004 JUNE 15, OCTOBER 31, -- OCTOBER 31, 2004 2004 2004 - ---------------------------------------------------------------------------------------------- ADVISORY CLASS Actual $ 1,000.00 $ 1,002.40 $ 1.25 Hypothetical (5% average annual return before expenses) 1,000.00 1,017.74 1.26 </Table> * Expenses are equal to the Portfolio's annualized net expense ratio of 0.33%, multiplied by the average account value over the period, multiplied by 139/366 (to reflect the period).

THE ACCOMPANYING NOTES ARE AN INTEGRAL PART OF THE FINANCIAL STATEMENTS. 28 <Page> 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> <Caption> MAXIMUM EXPENSE RATIO --------------------------------------- ADVISORY INSTITUTIONAL INVESTOR ADVISORY PORTFOLIO FEE CLASS CLASS CLASS - -------------------------------------------------------------------------------- Money Market 0.15% 0.20% 0.30% 0.45% Prime 0.15 0.20 0.30 0.45 Government 0.15 0.20 0.30 0.45 Treasury 0.15 0.20 0.30 0.45 Tax-Exempt 0.15 0.20 0.30 0.45 </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 <Page> 2004 ANNUAL REPORT October 31, 2004 NOTES TO FINANCIAL STATEMENTS (CONT'D) MSIM, serves as the distributor of the Fund. The Fund has entered into an Administration Plan with respect to its Investor Class shares pursuant to which its Investor Class shares pay the Distributor a monthly or quarterly fee at an annual rate of up to 0.10% of the average daily net assets of such class of shares, to compensate certain financial intermediaries who provide administrative services to shareholders. The Fund has also entered into a Service and Shareholder Administration Plan with respect to its Advisory Class shares pursuant to which its Advisory Class shares pays the Distributor a monthly or quarterly fee at an annual rate of up to 0.25% of the average daily net assets of such class of shares, to compensate certain financial intermediaries who provide administrative services, personal and account maintenance services to shareholders. E. CUSTODIAN FEES: JPMorgan Chase Bank serves as custodian for the Fund in accordance with a custodian agreement. The Custodian holds cash, securities, and other assets of the fund as required by the 1940 Act. F. FEDERAL INCOME TAXES: It is each Portfolio's intention to qualify as a regulated investment company and distribute all of its taxable and tax-exempt income. Accordingly, no provision for Federal income taxes is required in the financial statements. The tax character of distributions paid may differ from the character of distributions shown on the Statements of Changes in Net 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 as follows: <Table> <Caption> 2004 DISTRIBUTIONS PAID FROM: ------------------------ ORDINARY LONG-TERM INCOME CAPITAL GAIN PORTFOLIO (000) (000) - -------------------------------------------------------------------------------- Money Market $ 19,002 $ -- Prime 49,256 -- Government 1,004 -- Treasury 738 -- Tax-Exempt 735* -- </Table> * Distributions are tax-exempt The amount and character of income and gains to be distributed are determined in accordance with income tax regulations which may differ from U.S. generally accepted accounting principles. At October 31, 2004, the components of distributable earnings on a tax basis were as follows: <Table> <Caption> UNDISTRIBUTED ORDINARY INCOME PORTFOLIO (000) - ------------------------------------------------ Money Market $ 4,494 Prime 13,192 Government 661 Treasury 273 Tax-Exempt 180 </Table> At October 31, 2004, cost for U.S. Federal income tax purposes for the investments of the Portfolios were as follows: <Table> <Caption> COST PORTFOLIO (000) - ------------------------------------------------ Money Market $ 3,081,114 Prime 8,908,041 Government 548,290 Treasury 190,185 Tax-Exempt 166,335 </Table> At October 31, 2004, the Money Market Portfolio and Prime Portfolio had capital loss carryforwards for U.S. Federal income tax purposes of approximately $2,000 and $15,000, respectively, available to offset future capital gains which will expire on October 31, 2012. G. CONTRACTUAL OBLIGATIONS: The Fund enters into contracts that contain a variety of indemnifications. The Fund's maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote. H. ORGANIZATION AND/OR OFFERING COSTS: The Adviser has agreed to absorb any organization and/or offering costs associated with the opening of the Fund. I. OTHER: A portion of the securities of the Tax-Exempt Portfolio are insured by certain companies specializing in the insurance of municipal debt obligations. At October 31, 2004, approximately 14.9% of the net assets of the Tax-Exempt Portfolio are covered by such insurance. The insurers and their obligations are as follows: <Table> <Caption> PERCENTAGE OF INSURER NET ASSETS ------------------------------------------ AMBAC 4.8% FGIC 5.0 FSA 0.4 MBIA 4.7 </Table> At October 31, 2004, certain Portfolios had otherwise unaffiliated record owners of 10% or greater. Investment activities of these shareholders could have a material impact on these Portfolios. These Portfolios and the aggregate percentage of such owners were as follows: <Table> <Caption> PERCENTAGE OF OWNERSHIP -------------------------------------------- INSTITUTIONAL INVESTOR ADVISORY PORTFOLIO CLASS CLASS CLASS - -------------------------------------------------------------------------- Money Market -- -- 100.0% Prime 44.1% -- 100.0 Government 82.0 92.9% 92.8 Treasury 55.0 -- 100.0 Tax-Exempt 68.3 99.6 100.0 </Table> 30 <Page> 2004 ANNUAL REPORT October 31, 2004 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. /s/ Ernst & Young LLP Boston, Massachusetts December 10, 2004 31 <Page> 2004 ANNUAL REPORT October 31, 2004 FEDERAL TAX INFORMATION (UNAUDITED) For the year ended October 31, 2004, the percentage of income earned from direct U.S. Treasury Obligations for the Government Portfolio and Treasury Portfolio is 31.3% and 20.1%, respectively.

(e)(1) The audit committee's pre-approval policies and procedures are as follows: 3 <Page> 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: MORGAN STANLEY RETAIL FUNDS Morgan Stanley Investment Advisors Inc. Morgan Stanley & Co. Incorporated Morgan Stanley DW Inc.
