The non-subsidized yield reflects what the yield would have been had a fee and/or expense waiver not been in place during the period shown.

Money Market, Government, Government Securities, Treasury and Treasury Securities are STABLE NET ASSET VALUE ("NAV") FUNDS. You could lose money by investing in these Funds. Although the Funds seek to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. An investment in these Funds is not insured or guaranteed by the Federal Deposit Insurance Corporation ("FDIC") or any other government agency. Morgan Stanley and its affiliates (the "sponsor") has no legal obligation to provide financial support to the Funds, and you should not expect that the sponsor will provide financial support to the Funds at any time. Prime and Tax-Exempt are FLOATING NAV FUNDS. You could lose money by investing in these Funds. Because the share price of these Funds will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them. The Funds may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Funds' liquidity falls below required minimums because of market conditions or other factors. An investment in these Funds is not insured or guaranteed by the FDIC or any other government agency. The Funds' sponsor has no legal obligation to provide financial support to the Funds, and you should not expect that the sponsor will provide financial support to the Funds at any time. Please read the Trust's prospectuses carefully before you invest or send money.

The Tax-Exempt Portfolio may invest a portion of its total assets in bonds that may subject certain investors to the federal Alternative Minimum Tax ("AMT"). Investors should consult their tax adviser for further information on tax implications.

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

2023 Annual Report

October 31, 2023

Expense Examples (unaudited)

As a shareholder of a Fund, you incur ongoing costs, which might include advisory fees, administration fees, administration plan fees, service and shareholder administration plan fees, distribution plan fees, shareholder services plan fees and other Fund expenses. These examples are intended to help you understand your ongoing costs (in dollars) of investing in each Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

These examples are based on an investment of $1,000 invested at the beginning of the six-month period ended October 31, 2023 and held for the entire six-month period.

Actual Expenses

The table on the following page provides information about actual account values and actual expenses. You may use the information in this table, 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 table under the heading entitled "Actual Expenses Paid During Period" to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The table on the following page provides information about hypothetical account values and hypothetical expenses based on a Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund'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 a Fund 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.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only. Therefore, the information for each class in the table is useful in comparing ongoing costs, and will not help you determine the relative total cost of owning different funds that have transactional costs, such as sales charges (loads) or exchange fees.

2023 Annual Report

October 31, 2023

Investment Overview (unaudited)

Money Market Portfolio

The Money Market Portfolio seeks preservation of capital, daily liquidity and maximum current income. The Fund invests in liquid, high quality U.S. dollar-denominated money market instruments of U.S. and foreign financial and non-financial corporations. The Fund also invests in obligations of foreign governments and in obligations issued or guaranteed by the U.S. Government and its agencies and instrumentalities. The Fund's money market investments may include commercial paper, corporate debt obligations, debt obligations (including certificates of deposit and promissory notes) of U.S. banks or foreign banks, or of U.S. branches or subsidiaries of foreign banks, or foreign branches of U.S. banks (such as Yankee obligations), certificates of deposit of savings banks and savings and loan organizations, asset-backed securities, repurchase agreements and municipal obligations. In selecting investments, the Fund's "Adviser," Morgan Stanley Investment Management Inc., seeks to maintain the Fund's share price at $1.00. The share price remaining stable at $1.00 means that the Fund would preserve the principal value of your investment. There can be no assurance that the Fund will be able at all times to maintain its share price at $1.00. The Fund may also invest in U.S. dollar-denominated foreign securities and money market instruments. The Fund operates as a "retail money market fund," as such term is defined or interpreted under Rule 2a-7 under the Investment Company Act of 1940, as amended (the "1940 Act"). A "retail money market fund" is a money market fund that has policies and procedures reasonably designed to limit all beneficial owners of the fund to natural persons. As a "retail money market fund," the Fund may value its securities using the amortized cost method as permitted by Rule 2a-7 to seek to maintain a stable net asset value per share ("NAV") of $1.00. Like other money market funds of its type, the Fund is subject to the possible imposition of liquidity fees if the Fund's Board of Trustees determines that such fee is in the best interests of the Fund.

Performance

For the fiscal year ended October 31, 2023, the Fund's Wealth Share Class had a total return of 4.89%. For the seven-day period ended October 31, 2023, the Fund's Wealth Share Class provided an annualized current yield of 5.46% (subsidized) and 5.42% (non-subsidized), while its 30-day moving average annualized yield was 5.44% (subsidized) and 5.40% (non-subsidized). Yield quotation more closely reflects the current earnings of the Fund than the total return. The non-subsidized yield reflects what the yield would have been had a fee and/or expense waiver not been in place during the period shown. Past performance is no guarantee of future results.

Factors Affecting Performance

•  November 2022 began with the Federal Reserve (Fed) delivering its fourth consecutive 75 basis point⁽ⁱ⁾​ interest rate hike since the cycle began in March 2022, while indicating "ongoing increases" will be needed to achieve the Fed's objectives. Chair Powell left the door open to reducing the pace of hikes at future meetings, but clarified it was premature to consider a "pause" in rate increases. This meeting shifted the narrative in the markets, from a rapid hiking slope to a more measured one, albeit leading to a higher terminal (peak) rate. Although Fed speakers reinforced this posture during the month, the lower-than-expected inflation report caused markets to latch onto the pivot narrative and financial conditions eased significantly by the end of the month. Ahead of their blackout period, Fed officials closed the month by continuing to stress that inflation remains a major issue, and many in the market still forecast a terminal rate of 5% to 5.25% as a highly likely outcome.

•  As widely anticipated, the Fed slowed the pace of rate hikes at the December 2022 Federal Open Market Committee (FOMC or the Committee) meeting, increasing the target range by 50 basis points to the range of 4.25% to 4.50%. Updated dot plot forecasts showed that officials expected the terminal rate to reach 5.1% in 2023 before dropping back to 4.1% in 2024. The Committee additionally cited that "ongoing rate increases are likely appropriate" to continue tackling elevated inflation and a very tight labor market. The market priced in two additional rate hikes in early 2023 before a pause in the tightening cycle — a notable disconnect between market pricing and Fed communication.

•  Gross domestic product (GDP) readings came in stronger than consensus estimates for the fourth quarter of 2022, with the annualized rate of 2.9% beating the expected 2.6% growth rate and the market beginning to gravitate more toward the "soft-landing" outcome for the economy in 2023.⁽ⁱⁱ⁾​ This helped exaggerate the already existing disconnect between Fed communication and market pricing.

•  With respect to the labor market, the theme of resilience persisted throughout the fourth quarter of

2022 and into 2023. Payroll growth exceeded 500,000 jobs in the January 2023 report, coming after gains of 260,000 and 290,000 jobs in December and November 2022, respectively.⁽ⁱⁱⁱ⁾​ The unemployment rate, at 3.5%, matched the lowest reading in 70 years. Fed officials repeatedly cited the tightness in the labor market as a major contributor to inflation potentially becoming embedded moving forward and as a rationale for them not blinking in the fight against inflation.

•  The January 2023 consumer price index (CPI) numbers matched expectations, as the headline index increased by 0.5% month-over-month, while the core inflation gauge rose by 0.4% month-over-month. Combined with revisions to last year's readings, these data underscored that while inflation was most likely falling from its peak, progress was slower and more difficult than market participants would have liked. This caused the market to dilute some of the hope that had been building in the fourth quarter of 2022 when headline CPI rose 0.1% and 0.2% month-over-month in December and November, respectively. Markets were expected to remain focused on the variations in contributions from underlying components of CPI, such as used cars, in the months that followed.

•  The FOMC voted unanimously to increase the federal funds target rate by 0.25% to a range of 4.50% to 4.75% at the conclusion of its February 2023 meeting. The Committee noted that further rate hikes are "appropriate" in order to achieve "sufficiently restrictive" policy. The FOMC modified their messaging: in the post-meeting statement, it had previously discussed the "pace" of future rate increases, but now referred to the "extent" of future increases. This change didn't seem overly impactful on the surface, but it pointed to a Fed that was beginning to approach the end of its rate hiking cycle. Fed officials continued to monitor the economic outlook in effort to position policy accordingly. Market participants expected the Fed to continue raising rates into early summer 2023, as January 2023's employment figures far exceeded expectations.

•  At the March 2023 meeting, the FOMC voted unanimously to increase the federal funds target rate by 0.25% to a range of 4.75% to 5.00%. During the month, several high-profile regional banks came under significant pressure to meet withdrawals. The Fed and U.S. Treasury acted swiftly, securing

uninsured deposits and preventing widespread contagion by announcing a newly created Bank Term Funding Program. The new facility made additional funding available to ensure banks have the ability to meet the needs of their depositors. On the back of this announcement, the FOMC press release noted that the U.S. banking system was "sound and resilient," but these stresses were likely to result in tighter financial conditions and impact economic activity.

•  In the first quarter of 2023, U.S. GDP grew 2.2% (annualized). The jobs market remained strong, despite the Fed's aggressive pace of interest rate hikes. Monthly non-farm payrolls averaged 295,000 jobs per month added to the economy in the first three months of 2023, and the unemployment rate was 3.5% as of March 2023.

•  The FOMC voted unanimously to increase the federal funds target rate by 0.25% to a range of 5.00% to 5.25% at the conclusion of its May 2023 meeting. The press release was relatively unchanged from the prior meeting; however, it now included a softer stance on forward guidance. Concerns around regional banks continued to flare as J.P. Morgan purchased First Republic Bank after U.S. regulators took control. Market participants believed the Fed was likely to hold its policy rate steady at its June 2023 meeting as it paused to interpret incoming data, with employment remaining tight and inflation still running above target.

•  This pause materialized at the June 2023 meeting, as expected. The FOMC voted unanimously to maintain the federal funds target range at 5.00% to 5.25%. This was the first time since March 2022 that the Committee left rates unchanged. Market participants attempted to grasp whether this signaled a longer-term pause in policy rate movements.

•  The June 2023 meeting also included an update of the Fed's summary of economic projections. The dot plot showed officials' median projection for the benchmark rate at the end of 2023 increased 0.50% to 5.6%. The 2023 median GDP growth projection was upgraded 0.60% to 1.0%. The 2024 GDP growth forecast was lowered slightly to 1.1%. The 2023 unemployment rate estimate decreased 0.40% to 4.1%. The Fed reduced its median 2023 personal consumption expenditure (PCE) inflation forecast

to 3.2% in June, from 3.3% in March. The 2024 PCE projection was unchanged at 2.5%.

•  In July 2023, the FOMC voted unanimously to increase the federal funds target rate by 0.25% to a range of 5.25% to 5.50%. The accompanying press release included an upgrade to its characterization of economic growth from "modest" to "moderate," but the statement overall was mostly unchanged. The job market remained strong, and inflation continued to run above the Fed's target. In his press conference, Chair Powell explained that the Fed remains data-dependent going forward while market participants grappled with the validity of another hike later in 2023.

•  Economic data for the second quarter of 2023 continued to point to relative resilience in the U.S. economy. GDP growth rose 2.1% (annualized) in the April to June 2023 quarterly period. Monthly non-farm payrolls growth showed signs of slowing, averaging 240,000 jobs per month in the second quarter, while unemployment remained low, at 3.5% as of July 2023.

•  At the FOMC's next meeting in September 2023, officials voted to hold rates steady at a range of 5.25% to 5.50%. The press release was relatively unchanged aside from a minor adjustment in characterizing the economic expansion as "solid," from "moderate" previously. The release also noted that while job growth "remains strong" it had more recently "slowed."

•  The September 2023 meeting included an update of the Fed's summary of economic projections. The Fed's dot plot showed officials' median projection for the benchmark rate at the end of 2023 was unchanged at 5.6%. The 2023 median GDP growth projection was increased substantially 110 basis points to 2.1%. The 2024 GDP growth forecast improved as well to 1.5%. The 2023 unemployment rate estimate declined 30 basis points to 3.8%. The Fed increased its median 2023 PCE inflation forecast to 3.3% in September from 3.2% in June. The 2024 PCE projection was unchanged at 2.5%.

•  GDP accelerated strongly in the third quarter, rising 4.9% (annualized) on the back of robust consumer spending. The labor market continued to cool, with

monthly non-farm payrolls averaging 214,000 jobs per month in the third quarter of 2023 then slowing to 150,000 jobs in October 2023. The unemployment rate ticked higher to 3.9% as of October 2023.

•  With a unanimous 12-0 decision at the October 31 to November 1, 2023 meeting, the FOMC held rates constant at 22-year highs for a second straight meeting, leaving the target for the benchmark rate at 5.25% to 5.50%. The released statement said "tighter financial and credit conditions for households and businesses are likely to weigh on economic activity, hiring, and inflation," and this served as the Fed's main justification for leaving rates unchanged. Notably, during the subsequent press conference, Chair Powell indicated that risks are much more balanced as it pertains to additional tightening, which was a departure from previous meetings where he stated that the risk of doing too little outweighed the risk of doing too much. The dovish sentiment caused interest rates to rally, with the more policy-sensitive 2-year Treasury yield rallying 15 basis points, from 5.09% on October 31, 2023, to 4.94% at the close on November 1, 2023 (the day after the end of this reporting period).

Management Strategies

•  As of October 31, 2023, the Fund had net assets of approximately $2.1 billion. The Fund's weighted average maturity (WAM) and weighted average life (WAL) were 44 days and 59 days, respectively.

•  We remain comfortable in our conservative approach to managing this Fund, prioritizing portfolio positioning with elevated levels of liquidity. We believe our investment process and focus on credit research and risk management, combined with the high degree of liquidity and short maturity profile of the Fund, has put us in a favorable position to respond to both market events and potential changes to fiscal and monetary policy.

Investment Overview (unaudited)

Prime Portfolio

The Prime Portfolio seeks preservation of capital, daily liquidity and maximum current income. The Fund invests in liquid, high quality U.S. dollar-denominated money market instruments of U.S. and foreign financial corporations and U.S. non-financial corporations. The Fund also invests in obligations issued or guaranteed by the U.S. Government and its agencies and instrumentalities. The Fund's money market investments may include commercial paper, corporate debt obligations, debt obligations (including certificates of deposit and promissory notes) of U.S. banks or foreign banks, or of U.S. branches or subsidiaries of foreign banks, or foreign branches of U.S. banks (such as Yankee obligations), certificates of deposit of savings banks and savings and loan organizations, asset-backed securities, repurchase agreements and municipal obligations. The Fund may also invest in U.S. dollar-denominated foreign securities and money market instruments. The Fund operates as an "institutional money market fund," which is neither a "government money market fund" nor "retail money market fund" as such terms are defined or interpreted under Rule 2a-7 under the Investment Company Act of 1940, as amended ("Rule 2a-7" under the "1940 Act"). As such, the Fund is required to price and transact in its shares at a net asset value per share ("NAV") reflecting market-based values of its portfolio holdings (i.e., at a "floating" NAV), rounded to a minimum of the fourth decimal place. Like other money market funds of its type, the Fund is subject to the possible imposition of liquidity fees if the Fund's Board of Trustees determines that such fee is in the best interests of the Fund.

Performance

For the fiscal year ended October 31, 2023, the Fund's Institutional Share Class had a total return of 5.02%. For the seven-day period ended October 31, 2023, the Fund's Institutional Share Class provided an annualized current yield of 5.46% (subsidized) 5.45% (non-subsidized), while its 30-day moving average annualized yield was 5.45% (subsidized) and 5.44% (non-subsidized). Yield quotation more closely reflects the current earnings of the Fund than the total return. The non-subsidized yield reflects what the yield would have been had a fee and/or expense waiver not been in place during the period shown. Past performance is no guarantee of future results.

Factors Affecting Performance

•  November 2022 began with the Federal Reserve (Fed) delivering its fourth consecutive 75 basis point⁽ⁱ⁾​ interest rate hike since the cycle began in March 2022, while indicating "ongoing increases" will be needed to achieve the Fed's objectives. Chair

Powell left the door open to reducing the pace of hikes at future meetings, but clarified it was premature to consider a "pause" in rate increases. This meeting shifted the narrative in the markets, from a rapid hiking slope to a more measured one, albeit leading to a higher terminal (peak) rate. Although Fed speakers reinforced this posture during the month, the lower-than-expected inflation report caused markets to latch onto the pivot narrative and financial conditions eased significantly by the end of the month. Ahead of their blackout period, Fed officials closed the month by continuing to stress that inflation remains a major issue, and many in the market still forecast a terminal rate of 5% to 5.25% as a highly likely outcome.

•  As widely anticipated, the Fed slowed the pace of rate hikes at the December 2022 Federal Open Market Committee (FOMC or the Committee) meeting, increasing the target range by 50 basis points to the range of 4.25% to 4.50%. Updated dot plot forecasts showed that officials expected the terminal rate to reach 5.1% in 2023 before dropping back to 4.1% in 2024. The Committee additionally cited that "ongoing rate increases are likely appropriate" to continue tackling elevated inflation and a very tight labor market. The market priced in two additional rate hikes in early 2023 before a pause in the tightening cycle — a notable disconnect between market pricing and Fed communication.

•  Gross domestic product (GDP) readings came in stronger than consensus estimates for the fourth quarter of 2022, with the annualized rate of 2.9% beating the expected 2.6% growth rate and the market beginning to gravitate more toward the "soft-landing" outcome for the economy in 2023.⁽ⁱⁱ⁾​ This helped exaggerate the already existing disconnect between Fed communication and market pricing.

•  With respect to the labor market, the theme of resilience persisted throughout the fourth quarter of 2022 and into 2023. Payroll growth exceeded 500,000 jobs in the January 2023 report, coming after gains of 260,000 and 290,000 jobs in December and November 2022, respectively.⁽ⁱⁱⁱ⁾​ The unemployment rate, at 3.5%, matched the lowest reading in 70 years. Fed officials repeatedly cited the tightness in the labor market as a major contributor

to inflation potentially becoming embedded moving forward and as a rationale for them not blinking in the fight against inflation.

•  The January 2023 consumer price index (CPI) numbers matched expectations, as the headline index increased by 0.5% month-over-month, while the core inflation gauge rose by 0.4% month-over-month. Combined with revisions to last year's readings, these data underscored that while inflation was most likely falling from its peak, progress was slower and more difficult than market participants would have liked. This caused the market to dilute some of the hope that had been building in the fourth quarter of 2022 when headline CPI rose 0.1% and 0.2% month-over-month in December and November, respectively. Markets were expected to remain focused on the variations in contributions from underlying components of CPI, such as used cars, in the months that followed.

•  The FOMC voted unanimously to increase the federal funds target rate by 0.25% to a range of 4.50% to 4.75% at the conclusion of its February 2023 meeting. The Committee noted that further rate hikes are "appropriate" in order to achieve "sufficiently restrictive" policy. The FOMC modified their messaging: in the post-meeting statement, it had previously discussed the "pace" of future rate increases, but now referred to the "extent" of future increases. This change didn't seem overly impactful on the surface, but it pointed to a Fed that was beginning to approach the end of its rate hiking cycle. Fed officials continued to monitor the economic outlook in effort to position policy accordingly. Market participants expected the Fed to continue raising rates into early summer 2023, as January 2023's employment figures far exceeded expectations.

•  At the March 2023 meeting, the FOMC voted unanimously to increase the federal funds target rate by 0.25% to a range of 4.75% to 5.00%. During the month, several high-profile regional banks came under significant pressure to meet withdrawals. The Fed and U.S. Treasury acted swiftly, securing uninsured deposits and preventing widespread contagion by announcing a newly created Bank Term Funding Program. The new facility made additional funding available to ensure banks have the ability to meet the needs of their depositors. On

the back of this announcement, the FOMC press release noted that the U.S. banking system was "sound and resilient," but these stresses were likely to result in tighter financial conditions and impact economic activity.

•  In the first quarter of 2023, U.S. GDP grew 2.2% (annualized). The jobs market remained strong, despite the Fed's aggressive pace of interest rate hikes. Monthly non-farm payrolls averaged 295,000 jobs per month added to the economy in the first three months of 2023, and the unemployment rate was 3.5% as of March 2023.

•  The FOMC voted unanimously to increase the federal funds target rate by 0.25% to a range of 5.00% to 5.25% at the conclusion of its May 2023 meeting. The press release was relatively unchanged from the prior meeting; however, it now included a softer stance on forward guidance. Concerns around regional banks continued to flare as J.P. Morgan purchased First Republic Bank after U.S. regulators took control. Market participants believed the Fed was likely to hold its policy rate steady at its June 2023 meeting as it paused to interpret incoming data, with employment remaining tight and inflation still running above target.

•  This pause materialized at the June 2023 meeting, as expected. The FOMC voted unanimously to maintain the federal funds target range at 5.00% to 5.25%. This was the first time since March 2022 that the Committee left rates unchanged. Market participants attempted to grasp whether this signaled a longer-term pause in policy rate movements.

•  The June 2023 meeting also included an update of the Fed's summary of economic projections. The dot plot showed officials' median projection for the benchmark rate at the end of 2023 increased 0.50% to 5.6%. The 2023 median GDP growth projection was upgraded 0.60% to 1.0%. The 2024 GDP growth forecast was lowered slightly to 1.1%. The 2023 unemployment rate estimate decreased 0.40% to 4.1%. The Fed reduced its median 2023 personal consumption expenditure (PCE) inflation forecast to 3.2% in June, from 3.3% in March. The 2024 PCE projection was unchanged at 2.5%.

•  In July 2023, the FOMC voted unanimously to increase the federal funds target rate by 0.25% to a range of 5.25% to 5.50%. The accompanying press release included an upgrade to its characterization of economic growth from "modest" to "moderate," but the statement overall was mostly unchanged. The job market remained strong, and inflation continued to run above the Fed's target. In his press conference, Chair Powell explained that the Fed remains data-dependent going forward while market participants grappled with the validity of another hike later in 2023.

•  Economic data for the second quarter of 2023 continued to point to relative resilience in the U.S. economy. GDP growth rose 2.1% (annualized) in the April to June 2023 quarterly period. Monthly non-farm payrolls growth showed signs of slowing, averaging 240,000 jobs per month in the second quarter, while unemployment remained low, at 3.5% as of July 2023.

•  At the FOMC's next meeting in September 2023, officials voted to hold rates steady at a range of 5.25% to 5.50%. The press release was relatively unchanged aside from a minor adjustment in characterizing the economic expansion as "solid," from "moderate" previously. The release also noted that while job growth "remains strong" it had more recently "slowed."

•  The September 2023 meeting included an update of the Fed's summary of economic projections. The Fed's dot plot showed officials' median projection for the benchmark rate at the end of 2023 was unchanged at 5.6%. The 2023 median GDP growth projection was increased substantially 110 basis points to 2.1%. The 2024 GDP growth forecast improved as well to 1.5%. The 2023 unemployment rate estimate declined 30 basis points to 3.8%. The Fed increased its median 2023 PCE inflation forecast to 3.3% in September from 3.2% in June. The 2024 PCE projection was unchanged at 2.5%.

•  GDP accelerated strongly in the third quarter, rising 4.9% (annualized) on the back of robust consumer spending. The labor market continued to cool, with monthly non-farm payrolls averaging 214,000 jobs per month in the third quarter of 2023 then slowing to 150,000 jobs in October 2023. The

unemployment rate ticked higher to 3.9% as of October 2023.

•  With a unanimous 12-0 decision at the October 31 to November 1, 2023 meeting, the FOMC held rates constant at 22-year highs for a second straight meeting, leaving the target for the benchmark rate at 5.25% to 5.50%. The released statement said "tighter financial and credit conditions for households and businesses are likely to weigh on economic activity, hiring, and inflation," and this served as the Fed's main justification for leaving rates unchanged. Notably, during the subsequent press conference, Chair Powell indicated that risks are much more balanced as it pertains to additional tightening, which was a departure from previous meetings where he stated that the risk of doing too little outweighed the risk of doing too much. The dovish sentiment caused interest rates to rally, with the more policy-sensitive 2-year Treasury yield rallying 15 basis points, from 5.09% on October 31, 2023, to 4.94% at the close on November 1, 2023 (the day after the end of this reporting period).

Management Strategies

•  As of October 31, 2023, the Fund had net assets of approximately $17.3 billion. The Fund's weighted average maturity (WAM) and weighted average life (WAL) were 44 days and 61 days, respectively.

•  We remain comfortable in our conservative approach to managing this Fund, prioritizing portfolio positioning with elevated levels of liquidity. We believe our investment process and focus on credit research and risk management, combined with the high degree of liquidity and short maturity profile of the Fund, has put us in a favorable position to respond to both market events and potential changes to fiscal and monetary policy.

2023 Annual Report

Investment Overview (unaudited)

Government Portfolio

The Government Portfolio seeks preservation of capital, daily liquidity and maximum current income. The Fund has adopted a policy to invest exclusively in obligations issued or guaranteed by the U.S. Government and its agencies and instrumentalities and in repurchase agreements collateralized by such securities in order to qualify as a "government money market fund" under federal regulations. The Fund may also hold cash from time to time. A "government money market fund" is a money market fund that invests at least 99.5% of its total assets in cash, securities issued or guaranteed by the United States or certain U.S. government agencies or instrumentalities and/or repurchase agreements that are collateralized fully by the foregoing. A "government money market fund" is exempt from requirements that permit money market funds to impose a "liquidity fee." In selecting investments, the Fund's "Adviser," Morgan Stanley Investment Management Inc., seeks to maintain the Fund's share price at $1.00. The share price remaining stable at $1.00 means that the Fund would preserve the principal value of your investment. In addition, the Fund has adopted a policy that provides, under normal circumstances, at least 80% of the Fund's assets will be invested in obligations issued or guaranteed by the U.S. Government and its agencies and instrumentalities and in repurchase agreements collateralized by such securities. This policy may be changed without shareholder approval; however, shareholders would be notified upon 60 days' notice in writing of any changes.

Performance

For the fiscal year ended October 31, 2023, the Fund's Institutional Share Class had a total return of 4.77%. For the seven-day period ended October 31, 2023, the Fund's Institutional Share Class provided an annualized current yield of 5.25% (subsidized) and 5.22% (non-subsidized), while its 30-day moving average annualized yield was 5.25% (subsidized) and 5.21% (non-subsidized.)

Factors Affecting Performance

•  November 2022 began with the Federal Reserve (Fed) delivering its fourth consecutive 75 basis point⁽ⁱ⁾​ interest rate hike since the cycle began in March 2022, while indicating "ongoing increases" will be needed to achieve the Fed's objectives. Chair Powell left the door open to reducing the pace of

hikes at future meetings, but clarified it was premature to consider a "pause" in rate increases. This meeting shifted the narrative in the markets, from a rapid hiking slope to a more measured one, albeit leading to a higher terminal (peak) rate. Although Fed speakers reinforced this posture during the month, the lower-than-expected inflation report caused markets to latch onto the pivot narrative and financial conditions eased significantly by the end of the month. Ahead of their blackout period, Fed officials closed the month by continuing to stress that inflation remains a major issue, and many in the market still forecast a terminal rate of 5% to 5.25% as a highly likely outcome.

•  As widely anticipated, the Fed slowed the pace of rate hikes at the December 2022 Federal Open Market Committee (FOMC or the Committee) meeting, increasing the target range by 50 basis points to the range of 4.25% to 4.50%. Updated dot plot forecasts showed that officials expected the terminal rate to reach 5.1% in 2023 before dropping back to 4.1% in 2024. The Committee additionally cited that "ongoing rate increases are likely appropriate" to continue tackling elevated inflation and a very tight labor market. The market priced in two additional rate hikes in early 2023 before a pause in the tightening cycle — a notable disconnect between market pricing and Fed communication.

•  Gross domestic product (GDP) readings came in stronger than consensus estimates for the fourth quarter of 2022, with the annualized rate of 2.9% beating the expected 2.6% growth rate and the market beginning to gravitate more toward the "soft-landing" outcome for the economy in 2023.⁽ⁱⁱ⁾​ This helped exaggerate the already existing disconnect between Fed communication and market pricing.

•  With respect to the labor market, the theme of resilience persisted throughout the fourth quarter of 2022 and into 2023. Payroll growth exceeded 500,000 jobs in the January 2023 report, coming after gains of 260,000 and 290,000 jobs in December and November 2022, respectively.⁽ⁱⁱⁱ⁾​ The unemployment rate, at 3.5%, matched the lowest reading in 70 years. Fed officials repeatedly cited the tightness in the labor market as a major contributor

to inflation potentially becoming embedded moving forward and as a rationale for them not blinking in the fight against inflation.

•  The January 2023 consumer price index (CPI) numbers matched expectations, as the headline index increased by 0.5% month-over-month, while the core inflation gauge rose by 0.4% month-over-month. Combined with revisions to last year's readings, these data underscored that while inflation was most likely falling from its peak, progress was slower and more difficult than market participants would have liked. This caused the market to dilute some of the hope that had been building in the fourth quarter of 2022 when headline CPI rose 0.1% and 0.2% month-over-month in December and November, respectively. Markets were expected to remain focused on the variations in contributions from underlying components of CPI, such as used cars, in the months that followed.

•  The FOMC voted unanimously to increase the federal funds target rate by 0.25% to a range of 4.50% to 4.75% at the conclusion of its February 2023 meeting. The Committee noted that further rate hikes are "appropriate" in order to achieve "sufficiently restrictive" policy. The FOMC modified their messaging: in the post-meeting statement, it had previously discussed the "pace" of future rate increases, but now referred to the "extent" of future increases. This change didn't seem overly impactful on the surface, but it pointed to a Fed that was beginning to approach the end of its rate hiking cycle. Fed officials continued to monitor the economic outlook in effort to position policy accordingly. Market participants expected the Fed to continue raising rates into early summer 2023, as January 2023's employment figures far exceeded expectations.

•  At the March 2023 meeting, the FOMC voted unanimously to increase the federal funds target rate by 0.25% to a range of 4.75% to 5.00%. During the month, several high-profile regional banks came under significant pressure to meet withdrawals. The Fed and U.S. Treasury acted swiftly, securing uninsured deposits and preventing widespread contagion by announcing a newly created Bank Term Funding Program. The new facility made additional funding available to ensure banks have the ability to meet the needs of their depositors. On

the back of this announcement, the FOMC press release noted that the U.S. banking system was "sound and resilient," but these stresses were likely to result in tighter financial conditions and impact economic activity.

•  In the first quarter of 2023, U.S. GDP grew 2.2% (annualized). The jobs market remained strong, despite the Fed's aggressive pace of interest rate hikes. Monthly non-farm payrolls averaged 295,000 jobs per month added to the economy in the first three months of 2023, and the unemployment rate was 3.5% as of March 2023.

•  The FOMC voted unanimously to increase the federal funds target rate by 0.25% to a range of 5.00% to 5.25% at the conclusion of its May 2023 meeting. The press release was relatively unchanged from the prior meeting; however, it now included a softer stance on forward guidance. Concerns around regional banks continued to flare as J.P. Morgan purchased First Republic Bank after U.S. regulators took control. Market participants believed the Fed was likely to hold its policy rate steady at its June 2023 meeting as it paused to interpret incoming data, with employment remaining tight and inflation still running above target.

•  This pause materialized at the June 2023 meeting, as expected. The FOMC voted unanimously to maintain the federal funds target range at 5.00% to 5.25%. This was the first time since March 2022 that the Committee left rates unchanged. Market participants attempted to grasp whether this signaled a longer-term pause in policy rate movements.

•  The June 2023 meeting also included an update of the Fed's summary of economic projections. The dot plot showed officials' median projection for the benchmark rate at the end of 2023 increased 0.50% to 5.6%. The 2023 median GDP growth projection was upgraded 0.60% to 1.0%. The 2024 GDP growth forecast was lowered slightly to 1.1%. The 2023 unemployment rate estimate decreased 0.40% to 4.1%. The Fed reduced its median 2023 personal consumption expenditure (PCE) inflation forecast to 3.2% in June, from 3.3% in March. The 2024 PCE projection was unchanged at 2.5%.

•  In July 2023, the FOMC voted unanimously to increase the federal funds target rate by 0.25% to a range of 5.25% to 5.50%. The accompanying press release included an upgrade to its characterization of economic growth from "modest" to "moderate," but the statement overall was mostly unchanged. The job market remained strong, and inflation continued to run above the Fed's target. In his press conference, Chair Powell explained that the Fed remains data-dependent going forward while market participants grappled with the validity of another hike later in 2023.

•  Economic data for the second quarter of 2023 continued to point to relative resilience in the U.S. economy. GDP growth rose 2.1% (annualized) in the April to June 2023 quarterly period. Monthly non-farm payrolls growth showed signs of slowing, averaging 240,000 jobs per month in the second quarter, while unemployment remained low, at 3.5% as of July 2023.

•  At the FOMC's next meeting in September 2023, officials voted to hold rates steady at a range of 5.25% to 5.50%. The press release was relatively unchanged aside from a minor adjustment in characterizing the economic expansion as "solid," from "moderate" previously. The release also noted that while job growth "remains strong" it had more recently "slowed."

•  The September 2023 meeting included an update of the Fed's summary of economic projections. The Fed's dot plot showed officials' median projection for the benchmark rate at the end of 2023 was unchanged at 5.6%. The 2023 median GDP growth projection was increased substantially 110 basis points to 2.1%. The 2024 GDP growth forecast improved as well to 1.5%. The 2023 unemployment rate estimate declined 30 basis points to 3.8%. The Fed increased its median 2023 PCE inflation forecast to 3.3% in September from 3.2% in June. The 2024 PCE projection was unchanged at 2.5%.

•  GDP accelerated strongly in the third quarter, rising 4.9% (annualized) on the back of robust consumer spending. The labor market continued to cool, with monthly non-farm payrolls averaging 214,000 jobs per month in the third quarter of 2023 then slowing to 150,000 jobs in October 2023. The

unemployment rate ticked higher to 3.9% as of October 2023.

•  With a unanimous 12-0 decision at the October 31 to November 1, 2023 meeting, the FOMC held rates constant at 22-year highs for a second straight meeting, leaving the target for the benchmark rate at 5.25% to 5.50%. The released statement said "tighter financial and credit conditions for households and businesses are likely to weigh on economic activity, hiring, and inflation," and this served as the Fed's main justification for leaving rates unchanged. Notably, during the subsequent press conference, Chair Powell indicated that risks are much more balanced as it pertains to additional tightening, which was a departure from previous meetings where he stated that the risk of doing too little outweighed the risk of doing too much. The dovish sentiment caused interest rates to rally, with the more policy-sensitive 2-year Treasury yield rallying 15 basis points, from 5.09% on October 31, 2023, to 4.94% at the close on November 1, 2023 (the day after the end of this reporting period).

Management Strategies

•  As of October 31, 2023, the Fund had net assets of approximately $143.4 billion. The Fund's weighted average maturity (WAM) and weighted average life (WAL) were 35 days and 92 days, respectively.

•  We continue to manage the portfolio to seek to be responsive to changes in market conditions and interest rate levels. We purchased U.S. Treasury and U.S. government agency debt and held a significant portion of the Fund in short-term repurchase agreements. We continued to focus on conservative positioning while seeking to maintain a competitive return for investors.

Government Securities Portfolio

The Government Securities Portfolio seeks preservation of capital, daily liquidity and maximum current income. The Fund has adopted a policy to invest substantially all of its assets in U.S. Treasury obligations and certain U.S. government securities, the interest from which is generally exempt from state income taxation, in order to qualify as a "government money market fund" under federal regulations. The Fund may also hold cash from time to time. A "government money market fund" is a money market fund that invests at least 99.5% of its total assets in cash, securities issued or guaranteed by the United States or certain U.S. government agencies or instrumentalities and/or repurchase agreements that are collateralized fully by the foregoing. A "government money market fund" is exempt from requirements that permit money market funds to impose a "liquidity fee." In selecting investments, the Fund's Adviser, Morgan Stanley Investment Management Inc., seeks to maintain the Fund's share price at $1.00. The share price remaining stable at $1.00 means that the Fund would preserve the principal value of your investment. The U.S. government securities that the Fund may purchase include those issued or guaranteed either by the U.S. Treasury or certain agencies, authorities or instrumentalities of the U.S. Government. The Fund may also invest in repurchase agreements with the Federal Reserve Bank of New York. In addition, the Fund has adopted a policy that provides, under normal circumstances, at least 80% of the Fund's assets will be invested in U.S. government securities. This policy may be changed without shareholder approval; however, shareholders would be notified upon 60 days' notice in writing of any changes.

Performance

For the fiscal period ended October 31, 2023, the Fund's Institutional Share Class had a total return of 4.71%. For the seven-day period ended October 31, 2023, the Fund's Institutional Share Class provide an annualized current yield of 5.20% (subsidized) and 5.19% (non subsidized), while its 30-day moving average annualized yield was 5.20% (subsidized) and 5.18% (non-subsidized). Yield quotation more closely reflects the current earnings of the Fund than the total return. The non-subsidized yield reflects what the yield would have been had a fee and/or expense waiver not been in place during the period shown. Past performance is no guarantee of future results.

Factors Affecting Performance

•  November 2022 began with the Federal Reserve (Fed) delivering its fourth consecutive 75 basis

point⁽ⁱ⁾​ interest rate hike since the cycle began in March 2022, while indicating "ongoing increases" will be needed to achieve the Fed's objectives. Chair Powell left the door open to reducing the pace of hikes at future meetings, but clarified it was premature to consider a "pause" in rate increases. This meeting shifted the narrative in the markets, from a rapid hiking slope to a more measured one, albeit leading to a higher terminal (peak) rate. Although Fed speakers reinforced this posture during the month, the lower-than-expected inflation report caused markets to latch onto the pivot narrative and financial conditions eased significantly by the end of the month. Ahead of their blackout period, Fed officials closed the month by continuing to stress that inflation remains a major issue, and many in the market still forecast a terminal rate of 5% to 5.25% as a highly likely outcome.

•  As widely anticipated, the Fed slowed the pace of rate hikes at the December 2022 Federal Open Market Committee (FOMC or the Committee) meeting, increasing the target range by 50 basis points to the range of 4.25% to 4.50%. Updated dot plot forecasts showed that officials expected the terminal rate to reach 5.1% in 2023 before dropping back to 4.1% in 2024. The Committee additionally cited that "ongoing rate increases are likely appropriate" to continue tackling elevated inflation and a very tight labor market. The market priced in two additional rate hikes in early 2023 before a pause in the tightening cycle — a notable disconnect between market pricing and Fed communication.

•  Gross domestic product (GDP) readings came in stronger than consensus estimates for the fourth quarter of 2022, with the annualized rate of 2.9% beating the expected 2.6% growth rate and the market beginning to gravitate more toward the "soft-landing" outcome for the economy in 2023.⁽ⁱⁱ⁾​ This helped exaggerate the already existing disconnect between Fed communication and market pricing.

•  With respect to the labor market, the theme of resilience persisted throughout the fourth quarter of 2022 and into 2023. Payroll growth exceeded 500,000 jobs in the January 2023 report, coming after gains of 260,000 and 290,000 jobs in

December and November 2022, respectively.⁽ⁱⁱⁱ⁾​ The unemployment rate, at 3.5%, matched the lowest reading in 70 years. Fed officials repeatedly cited the tightness in the labor market as a major contributor to inflation potentially becoming embedded moving forward and as a rationale for them not blinking in the fight against inflation.

•  The January 2023 consumer price index (CPI) numbers matched expectations, as the headline index increased by 0.5% month-over-month, while the core inflation gauge rose by 0.4% month-over-month. Combined with revisions to last year's readings, these data underscored that while inflation was most likely falling from its peak, progress was slower and more difficult than market participants would have liked. This caused the market to dilute some of the hope that had been building in the fourth quarter of 2022 when headline CPI rose 0.1% and 0.2% month-over-month in December and November, respectively. Markets were expected to remain focused on the variations in contributions from underlying components of CPI, such as used cars, in the months that followed.

•  The FOMC voted unanimously to increase the federal funds target rate by 0.25% to a range of 4.50% to 4.75% at the conclusion of its February 2023 meeting. The Committee noted that further rate hikes are "appropriate" in order to achieve "sufficiently restrictive" policy. The FOMC modified their messaging: in the post-meeting statement, it had previously discussed the "pace" of future rate increases, but now referred to the "extent" of future increases. This change didn't seem overly impactful on the surface, but it pointed to a Fed that was beginning to approach the end of its rate hiking cycle. Fed officials continued to monitor the economic outlook in effort to position policy accordingly. Market participants expected the Fed to continue raising rates into early summer 2023, as January 2023's employment figures far exceeded expectations.

•  At the March 2023 meeting, the FOMC voted unanimously to increase the federal funds target rate by 0.25% to a range of 4.75% to 5.00%. During the month, several high-profile regional banks came under significant pressure to meet withdrawals. The Fed and U.S. Treasury acted swiftly, securing uninsured deposits and preventing widespread

contagion by announcing a newly created Bank Term Funding Program. The new facility made additional funding available to ensure banks have the ability to meet the needs of their depositors. On the back of this announcement, the FOMC press release noted that the U.S. banking system was "sound and resilient," but these stresses were likely to result in tighter financial conditions and impact economic activity.

•  In the first quarter of 2023, U.S. GDP grew 2.2% (annualized). The jobs market remained strong, despite the Fed's aggressive pace of interest rate hikes. Monthly non-farm payrolls averaged 295,000 jobs per month added to the economy in the first three months of 2023, and the unemployment rate was 3.5% as of March 2023.

•  The FOMC voted unanimously to increase the federal funds target rate by 0.25% to a range of 5.00% to 5.25% at the conclusion of its May 2023 meeting. The press release was relatively unchanged from the prior meeting; however, it now included a softer stance on forward guidance. Concerns around regional banks continued to flare as J.P. Morgan purchased First Republic Bank after U.S. regulators took control. Market participants believed the Fed was likely to hold its policy rate steady at its June 2023 meeting as it paused to interpret incoming data, with employment remaining tight and inflation still running above target.

•  This pause materialized at the June 2023 meeting, as expected. The FOMC voted unanimously to maintain the federal funds target range at 5.00% to 5.25%. This was the first time since March 2022 that the Committee left rates unchanged. Market participants attempted to grasp whether this signaled a longer-term pause in policy rate movements.

•  The June 2023 meeting also included an update of the Fed's summary of economic projections. The dot plot showed officials' median projection for the benchmark rate at the end of 2023 increased 0.50% to 5.6%. The 2023 median GDP growth projection was upgraded 0.60% to 1.0%. The 2024 GDP growth forecast was lowered slightly to 1.1%. The 2023 unemployment rate estimate decreased 0.40% to 4.1%. The Fed reduced its median 2023 personal consumption expenditure (PCE) inflation forecast

to 3.2% in June, from 3.3% in March. The 2024 PCE projection was unchanged at 2.5%.

•  In July 2023, the FOMC voted unanimously to increase the federal funds target rate by 0.25% to a range of 5.25% to 5.50%. The accompanying press release included an upgrade to its characterization of economic growth from "modest" to "moderate," but the statement overall was mostly unchanged. The job market remained strong, and inflation continued to run above the Fed's target. In his press conference, Chair Powell explained that the Fed remains data-dependent going forward while market participants grappled with the validity of another hike later in 2023.

•  Economic data for the second quarter of 2023 continued to point to relative resilience in the U.S. economy. GDP growth rose 2.1% (annualized) in the April to June 2023 quarterly period. Monthly non-farm payrolls growth showed signs of slowing, averaging 240,000 jobs per month in the second quarter, while unemployment remained low, at 3.5% as of July 2023.

•  At the FOMC's next meeting in September 2023, officials voted to hold rates steady at a range of 5.25% to 5.50%. The press release was relatively unchanged aside from a minor adjustment in characterizing the economic expansion as "solid," from "moderate" previously. The release also noted that while job growth "remains strong" it had more recently "slowed."

•  The September 2023 meeting included an update of the Fed's summary of economic projections. The Fed's dot plot showed officials' median projection for the benchmark rate at the end of 2023 was unchanged at 5.6%. The 2023 median GDP growth projection was increased substantially 110 basis points to 2.1%. The 2024 GDP growth forecast improved as well to 1.5%. The 2023 unemployment rate estimate declined 30 basis points to 3.8%. The Fed increased its median 2023 PCE inflation forecast to 3.3% in September from 3.2% in June. The 2024 PCE projection was unchanged at 2.5%.

•  GDP accelerated strongly in the third quarter, rising 4.9% (annualized) on the back of robust consumer spending. The labor market continued to cool, with

monthly non-farm payrolls averaging 214,000 jobs per month in the third quarter of 2023 then slowing to 150,000 jobs in October 2023. The unemployment rate ticked higher to 3.9% as of October 2023.

•  With a unanimous 12-0 decision at the October 31 to November 1, 2023 meeting, the FOMC held rates constant at 22-year highs for a second straight meeting, leaving the target for the benchmark rate at 5.25% to 5.50%. The released statement said "tighter financial and credit conditions for households and businesses are likely to weigh on economic activity, hiring, and inflation," and this served as the Fed's main justification for leaving rates unchanged. Notably, during the subsequent press conference, Chair Powell indicated that risks are much more balanced as it pertains to additional tightening, which was a departure from previous meetings where he stated that the risk of doing too little outweighed the risk of doing too much. The dovish sentiment caused interest rates to rally, with the more policy-sensitive 2-year Treasury yield rallying 15 basis points, from 5.09% on October 31, 2023, to 4.94% at the close on November 1, 2023 (the day after the end of this reporting period).

Management Strategies

•  As of October 31, 2023, the Fund had net assets of approximately $5.7 billion. The Fund's weighted average maturity (WAM) and weighted average life (WAL) were 32 days and 78 days, respectively.

•  We continue to manage the portfolio to be responsive to changes in market conditions and interest rate levels. We purchased U.S. Treasury and U.S. government agency debt in both fixed-rate and floating-rate structures and remained focused on portfolio liquidity while maintaining a competitive return for investors.

Treasury Portfolio

The Treasury Portfolio seeks preservation of capital, daily liquidity and maximum current income. The Fund has adopted a policy to invest exclusively in U.S. Treasury obligations, which are backed by the full faith and credit of the United States, and repurchase agreements collateralized by such securities in order to qualify as a "government money market fund" under federal regulations. The Fund may also hold cash from time to time. A "government money market fund" is a money market fund that invests at least 99.5% of its total assets in cash, securities issued or guaranteed by the United States or certain U.S. government agencies or instrumentalities and/or repurchase agreements that are collateralized fully by the foregoing. A "government money market fund" is exempt from requirements that permit money market funds to impose a "liquidity fee." In selecting investments, the Fund's "Adviser," Morgan Stanley Investment Management Inc., seeks to maintain the Fund's share price at $1.00. The share price remaining stable at $1.00 means that the Fund would preserve the principal value of your investment. In addition, the Fund has adopted a policy that provides, under normal circumstances, at least 80% of the Fund's assets will be invested in U.S. Treasury obligations, which are backed by the full faith and credit of the United States, and repurchase agreements collateralized by such securities. This policy may be changed without shareholder approval; however, shareholders would be notified upon 60 days' notice in writing of any changes.

Performance

For the fiscal period ended October 31, 2023, the Fund's Institutional Share Class had a total return of 4.72%. For the seven-day period ended October 31, 2023, the Fund's Institutional Share Class provide an annualized current yield of 5.22% (subsidized) and 5.21% (non-subsidized), while its 30-day moving average annualized yield was 5.21% and 5.20% (non-subsidized). Yield quotation more closely reflects the current earnings of the Fund than the total return. The non-subsidized yield reflects what the yield would have been had a fee and/or expense waiver not been in place during the period shown. Past performance is no guarantee of future results.

Factors Affecting Performance

•  November 2022 began with the Federal Reserve (Fed) delivering its fourth consecutive 75 basis point⁽ⁱ⁾​ interest rate hike since the cycle began in March 2022, while indicating "ongoing increases" will be needed to achieve the Fed's objectives. Chair Powell left the door open to reducing the pace of

hikes at future meetings, but clarified it was premature to consider a "pause" in rate increases. This meeting shifted the narrative in the markets, from a rapid hiking slope to a more measured one, albeit leading to a higher terminal (peak) rate. Although Fed speakers reinforced this posture during the month, the lower-than-expected inflation report caused markets to latch onto the pivot narrative and financial conditions eased significantly by the end of the month. Ahead of their blackout period, Fed officials closed the month by continuing to stress that inflation remains a major issue, and many in the market still forecast a terminal rate of 5% to 5.25% as a highly likely outcome.

•  As widely anticipated, the Fed slowed the pace of rate hikes at the December 2022 Federal Open Market Committee (FOMC or the Committee) meeting, increasing the target range by 50 basis points to the range of 4.25% to 4.50%. Updated dot plot forecasts showed that officials expected the terminal rate to reach 5.1% in 2023 before dropping back to 4.1% in 2024. The Committee additionally cited that "ongoing rate increases are likely appropriate" to continue tackling elevated inflation and a very tight labor market. The market priced in two additional rate hikes in early 2023 before a pause in the tightening cycle — a notable disconnect between market pricing and Fed communication.

•  Gross domestic product (GDP) readings came in stronger than consensus estimates for the fourth quarter of 2022, with the annualized rate of 2.9% beating the expected 2.6% growth rate and the market beginning to gravitate more toward the "soft-landing" outcome for the economy in 2023.⁽ⁱⁱ⁾​ This helped exaggerate the already existing disconnect between Fed communication and market pricing.

•  With respect to the labor market, the theme of resilience persisted throughout the fourth quarter of 2022 and into 2023. Payroll growth exceeded 500,000 jobs in the January 2023 report, coming after gains of 260,000 and 290,000 jobs in December and November 2022, respectively.⁽ⁱⁱⁱ⁾​ The unemployment rate, at 3.5%, matched the lowest reading in 70 years. Fed officials repeatedly cited the tightness in the labor market as a major contributor

to inflation potentially becoming embedded moving forward and as a rationale for them not blinking in the fight against inflation.

•  The January 2023 consumer price index (CPI) numbers matched expectations, as the headline index increased by 0.5% month-over-month, while the core inflation gauge rose by 0.4% month-over-month. Combined with revisions to last year's readings, these data underscored that while inflation was most likely falling from its peak, progress was slower and more difficult than market participants would have liked. This caused the market to dilute some of the hope that had been building in the fourth quarter of 2022 when headline CPI rose 0.1% and 0.2% month-over-month in December and November, respectively. Markets were expected to remain focused on the variations in contributions from underlying components of CPI, such as used cars, in the months that followed.

•  The FOMC voted unanimously to increase the federal funds target rate by 0.25% to a range of 4.50% to 4.75% at the conclusion of its February 2023 meeting. The Committee noted that further rate hikes are "appropriate" in order to achieve "sufficiently restrictive" policy. The FOMC modified their messaging: in the post-meeting statement, it had previously discussed the "pace" of future rate increases, but now referred to the "extent" of future increases. This change didn't seem overly impactful on the surface, but it pointed to a Fed that was beginning to approach the end of its rate hiking cycle. Fed officials continued to monitor the economic outlook in effort to position policy accordingly. Market participants expected the Fed to continue raising rates into early summer 2023, as January 2023's employment figures far exceeded expectations.

•  At the March 2023 meeting, the FOMC voted unanimously to increase the federal funds target rate by 0.25% to a range of 4.75% to 5.00%. During the month, several high-profile regional banks came under significant pressure to meet withdrawals. The Fed and U.S. Treasury acted swiftly, securing uninsured deposits and preventing widespread contagion by announcing a newly created Bank Term Funding Program. The new facility made additional funding available to ensure banks have the ability to meet the needs of their depositors. On

the back of this announcement, the FOMC press release noted that the U.S. banking system was "sound and resilient," but these stresses were likely to result in tighter financial conditions and impact economic activity.

•  In the first quarter of 2023, U.S. GDP grew 2.2% (annualized). The jobs market remained strong, despite the Fed's aggressive pace of interest rate hikes. Monthly non-farm payrolls averaged 295,000 jobs per month added to the economy in the first three months of 2023, and the unemployment rate was 3.5% as of March 2023.

•  The FOMC voted unanimously to increase the federal funds target rate by 0.25% to a range of 5.00% to 5.25% at the conclusion of its May 2023 meeting. The press release was relatively unchanged from the prior meeting; however, it now included a softer stance on forward guidance. Concerns around regional banks continued to flare as J.P. Morgan purchased First Republic Bank after U.S. regulators took control. Market participants believed the Fed was likely to hold its policy rate steady at its June 2023 meeting as it paused to interpret incoming data, with employment remaining tight and inflation still running above target.

•  This pause materialized at the June 2023 meeting, as expected. The FOMC voted unanimously to maintain the federal funds target range at 5.00% to 5.25%. This was the first time since March 2022 that the Committee left rates unchanged. Market participants attempted to grasp whether this signaled a longer-term pause in policy rate movements.

•  The June 2023 meeting also included an update of the Fed's summary of economic projections. The dot plot showed officials' median projection for the benchmark rate at the end of 2023 increased 0.50% to 5.6%. The 2023 median GDP growth projection was upgraded 0.60% to 1.0%. The 2024 GDP growth forecast was lowered slightly to 1.1%. The 2023 unemployment rate estimate decreased 0.40% to 4.1%. The Fed reduced its median 2023 personal consumption expenditure (PCE) inflation forecast to 3.2% in June, from 3.3% in March. The 2024 PCE projection was unchanged at 2.5%.

•  In July 2023, the FOMC voted unanimously to increase the federal funds target rate by 0.25% to a range of 5.25% to 5.50%. The accompanying press release included an upgrade to its characterization of economic growth from "modest" to "moderate," but the statement overall was mostly unchanged. The job market remained strong, and inflation continued to run above the Fed's target. In his press conference, Chair Powell explained that the Fed remains data-dependent going forward while market participants grappled with the validity of another hike later in 2023.

•  Economic data for the second quarter of 2023 continued to point to relative resilience in the U.S. economy. GDP growth rose 2.1% (annualized) in the April to June 2023 quarterly period. Monthly non-farm payrolls growth showed signs of slowing, averaging 240,000 jobs per month in the second quarter, while unemployment remained low, at 3.5% as of July 2023.

•  At the FOMC's next meeting in September 2023, officials voted to hold rates steady at a range of 5.25% to 5.50%. The press release was relatively unchanged aside from a minor adjustment in characterizing the economic expansion as "solid," from "moderate" previously. The release also noted that while job growth "remains strong" it had more recently "slowed."

•  The September 2023 meeting included an update of the Fed's summary of economic projections. The Fed's dot plot showed officials' median projection for the benchmark rate at the end of 2023 was unchanged at 5.6%. The 2023 median GDP growth projection was increased substantially 110 basis points to 2.1%. The 2024 GDP growth forecast improved as well to 1.5%. The 2023 unemployment rate estimate declined 30 basis points to 3.8%. The Fed increased its median 2023 PCE inflation forecast to 3.3% in September from 3.2% in June. The 2024 PCE projection was unchanged at 2.5%.

•  GDP accelerated strongly in the third quarter, rising 4.9% (annualized) on the back of robust consumer spending. The labor market continued to cool, with monthly non-farm payrolls averaging 214,000 jobs per month in the third quarter of 2023 then slowing to 150,000 jobs in October 2023. The

unemployment rate ticked higher to 3.9% as of October 2023.

•  With a unanimous 12-0 decision at the October 31 to November 1, 2023 meeting, the FOMC held rates constant at 22-year highs for a second straight meeting, leaving the target for the benchmark rate at 5.25% to 5.50%. The released statement said "tighter financial and credit conditions for households and businesses are likely to weigh on economic activity, hiring, and inflation," and this served as the Fed's main justification for leaving rates unchanged. Notably, during the subsequent press conference, Chair Powell indicated that risks are much more balanced as it pertains to additional tightening, which was a departure from previous meetings where he stated that the risk of doing too little outweighed the risk of doing too much. The dovish sentiment caused interest rates to rally, with the more policy-sensitive 2-year Treasury yield rallying 15 basis points, from 5.09% on October 31, 2023, to 4.94% at the close on November 1, 2023 (the day after the end of this reporting period).

Management Strategies

•  As of October 31, 2023, the Fund had net assets of approximately $32.0 billion. The Fund's weighted average maturity (WAM) and weighted average life (WAL) were 22 days and 72 days, respectively.

•  We continued to manage the portfolio to be responsive to changes in market conditions and interest rate levels. We purchased U.S. Treasuries and held a significant portion of the portfolio in short-term repurchase agreements, collateralized by U.S. Treasury obligations. We remained focused on portfolio liquidity and conservative positioning while seeking to maintain a competitive return for investors.

Investment Overview (unaudited)

Treasury Securities Portfolio

The Treasury Securities Portfolio seeks preservation of capital, daily liquidity and maximum current income. The Fund has adopted a policy to invest exclusively in U.S. Treasury obligations, which are backed by the full faith and credit of the United States, in order to qualify as a "government money market fund" under federal regulations. The Fund may also hold cash from time to time. A "government money market fund" is a money market fund that invests at least 99.5% of its total assets in cash, securities issued or guaranteed by the United States or certain U.S. government agencies or instrumentalities and/or repurchase agreements that are collateralized fully by the foregoing. A "government money market fund" is exempt from requirements that permit money market funds to impose a "liquidity fee." In selecting investments, the Fund's "Adviser," Morgan Stanley Investment Management Inc., seeks to maintain the Fund's share price at $1.00. The share price remaining stable at $1.00 means that the Fund would preserve the principal value of your investment. In addition, the Fund has adopted a policy that provides, under normal circumstances, at least 80% of the Fund's assets will be invested in U.S. Treasury obligations, which are backed by the full faith and credit of the United States. This policy may be changed without shareholder approval; however, shareholders would be notified upon 60 days' notice in writing of any changes.

Performance

For the fiscal year ended October 31, 2023, the Fund's Institutional Share Class had a total return of 4.63%. For the seven-day period ended October 31, 2023, the Fund's Institutional Share Class provided an annualized current yield of 5.24% (subsidized) and 5.24% (non-subsidized), while its 30-day moving average annualized yield was 5.23% (subsidized) and 5.22% (non-subsidized). Yield quotation more closely reflects the current earnings of the Fund than the total return. The non-subsidized yield reflects what the yield would have been had a fee and/or expense waiver not been in place during the period shown. Past performance is no guarantee of future results.

Factors Affecting Performance

•  November 2022 began with the Federal Reserve (Fed) delivering its fourth consecutive 75 basis point⁽ⁱ⁾​ interest rate hike since the cycle began in March 2022, while indicating "ongoing increases" will be needed to achieve the Fed's objectives. Chair Powell left the door open to reducing the pace of hikes at future meetings, but clarified it was

premature to consider a "pause" in rate increases. This meeting shifted the narrative in the markets, from a rapid hiking slope to a more measured one, albeit leading to a higher terminal (peak) rate. Although Fed speakers reinforced this posture during the month, the lower-than-expected inflation report caused markets to latch onto the pivot narrative and financial conditions eased significantly by the end of the month. Ahead of their blackout period, Fed officials closed the month by continuing to stress that inflation remains a major issue, and many in the market still forecast a terminal rate of 5% to 5.25% as a highly likely outcome.

•  As widely anticipated, the Fed slowed the pace of rate hikes at the December 2022 Federal Open Market Committee (FOMC or the Committee) meeting, increasing the target range by 50 basis points to the range of 4.25% to 4.50%. Updated dot plot forecasts showed that officials expected the terminal rate to reach 5.1% in 2023 before dropping back to 4.1% in 2024. The Committee additionally cited that "ongoing rate increases are likely appropriate" to continue tackling elevated inflation and a very tight labor market. The market priced in two additional rate hikes in early 2023 before a pause in the tightening cycle — a notable disconnect between market pricing and Fed communication.

•  Gross domestic product (GDP) readings came in stronger than consensus estimates for the fourth quarter of 2022, with the annualized rate of 2.9% beating the expected 2.6% growth rate and the market beginning to gravitate more toward the "soft-landing" outcome for the economy in 2023.⁽ⁱⁱ⁾​ This helped exaggerate the already existing disconnect between Fed communication and market pricing.

•  With respect to the labor market, the theme of resilience persisted throughout the fourth quarter of 2022 and into 2023. Payroll growth exceeded 500,000 jobs in the January 2023 report, coming after gains of 260,000 and 290,000 jobs in December and November 2022, respectively.⁽ⁱⁱⁱ⁾​ The unemployment rate, at 3.5%, matched the lowest reading in 70 years. Fed officials repeatedly cited the tightness in the labor market as a major contributor to inflation potentially becoming embedded moving

forward and as a rationale for them not blinking in the fight against inflation.

•  The January 2023 consumer price index (CPI) numbers matched expectations, as the headline index increased by 0.5% month-over-month, while the core inflation gauge rose by 0.4% month-over-month. Combined with revisions to last year's readings, these data underscored that while inflation was most likely falling from its peak, progress was slower and more difficult than market participants would have liked. This caused the market to dilute some of the hope that had been building in the fourth quarter of 2022 when headline CPI rose 0.1% and 0.2% month-over-month in December and November, respectively. Markets were expected to remain focused on the variations in contributions from underlying components of CPI, such as used cars, in the months that followed.

•  The FOMC voted unanimously to increase the federal funds target rate by 0.25% to a range of 4.50% to 4.75% at the conclusion of its February 2023 meeting. The Committee noted that further rate hikes are "appropriate" in order to achieve "sufficiently restrictive" policy. The FOMC modified their messaging: in the post-meeting statement, it had previously discussed the "pace" of future rate increases, but now referred to the "extent" of future increases. This change didn't seem overly impactful on the surface, but it pointed to a Fed that was beginning to approach the end of its rate hiking cycle. Fed officials continued to monitor the economic outlook in effort to position policy accordingly. Market participants expected the Fed to continue raising rates into early summer 2023, as January 2023's employment figures far exceeded expectations.

•  At the March 2023 meeting, the FOMC voted unanimously to increase the federal funds target rate by 0.25% to a range of 4.75% to 5.00%. During the month, several high-profile regional banks came under significant pressure to meet withdrawals. The Fed and U.S. Treasury acted swiftly, securing uninsured deposits and preventing widespread contagion by announcing a newly created Bank Term Funding Program. The new facility made additional funding available to ensure banks have the ability to meet the needs of their depositors. On the back of this announcement, the FOMC press

release noted that the U.S. banking system was "sound and resilient," but these stresses were likely to result in tighter financial conditions and impact economic activity.

•  In the first quarter of 2023, U.S. GDP grew 2.2% (annualized). The jobs market remained strong, despite the Fed's aggressive pace of interest rate hikes. Monthly non-farm payrolls averaged 295,000 jobs per month added to the economy in the first three months of 2023, and the unemployment rate was 3.5% as of March 2023.

•  The FOMC voted unanimously to increase the federal funds target rate by 0.25% to a range of 5.00% to 5.25% at the conclusion of its May 2023 meeting. The press release was relatively unchanged from the prior meeting; however, it now included a softer stance on forward guidance. Concerns around regional banks continued to flare as J.P. Morgan purchased First Republic Bank after U.S. regulators took control. Market participants believed the Fed was likely to hold its policy rate steady at its June 2023 meeting as it paused to interpret incoming data, with employment remaining tight and inflation still running above target.

•  This pause materialized at the June 2023 meeting, as expected. The FOMC voted unanimously to maintain the federal funds target range at 5.00% to 5.25%. This was the first time since March 2022 that the Committee left rates unchanged. Market participants attempted to grasp whether this signaled a longer-term pause in policy rate movements.

•  The June 2023 meeting also included an update of the Fed's summary of economic projections. The dot plot showed officials' median projection for the benchmark rate at the end of 2023 increased 0.50% to 5.6%. The 2023 median GDP growth projection was upgraded 0.60% to 1.0%. The 2024 GDP growth forecast was lowered slightly to 1.1%. The 2023 unemployment rate estimate decreased 0.40% to 4.1%. The Fed reduced its median 2023 personal consumption expenditure (PCE) inflation forecast to 3.2% in June, from 3.3% in March. The 2024 PCE projection was unchanged at 2.5%.

•  In July 2023, the FOMC voted unanimously to increase the federal funds target rate by 0.25% to a

range of 5.25% to 5.50%. The accompanying press release included an upgrade to its characterization of economic growth from "modest" to "moderate," but the statement overall was mostly unchanged. The job market remained strong, and inflation continued to run above the Fed's target. In his press conference, Chair Powell explained that the Fed remains data-dependent going forward while market participants grappled with the validity of another hike later in 2023.

•  Economic data for the second quarter of 2023 continued to point to relative resilience in the U.S. economy. GDP growth rose 2.1% (annualized) in the April to June 2023 quarterly period. Monthly non-farm payrolls growth showed signs of slowing, averaging 240,000 jobs per month in the second quarter, while unemployment remained low, at 3.5% as of July 2023.

•  At the FOMC's next meeting in September 2023, officials voted to hold rates steady at a range of 5.25% to 5.50%. The press release was relatively unchanged aside from a minor adjustment in characterizing the economic expansion as "solid," from "moderate" previously. The release also noted that while job growth "remains strong" it had more recently "slowed."

•  The September 2023 meeting included an update of the Fed's summary of economic projections. The Fed's dot plot showed officials' median projection for the benchmark rate at the end of 2023 was unchanged at 5.6%. The 2023 median GDP growth projection was increased substantially 110 basis points to 2.1%. The 2024 GDP growth forecast improved as well to 1.5%. The 2023 unemployment rate estimate declined 30 basis points to 3.8%. The Fed increased its median 2023 PCE inflation forecast to 3.3% in September from 3.2% in June. The 2024 PCE projection was unchanged at 2.5%.

•  GDP accelerated strongly in the third quarter, rising 4.9% (annualized) on the back of robust consumer spending. The labor market continued to cool, with monthly non-farm payrolls averaging 214,000 jobs per month in the third quarter of 2023 then slowing to 150,000 jobs in October 2023. The unemployment rate ticked higher to 3.9% as of October 2023.

•  With a unanimous 12-0 decision at the October 31 to November 1, 2023 meeting, the FOMC held rates constant at 22-year highs for a second straight meeting, leaving the target for the benchmark rate at 5.25% to 5.50%. The released statement said "tighter financial and credit conditions for households and businesses are likely to weigh on economic activity, hiring, and inflation," and this served as the Fed's main justification for leaving rates unchanged. Notably, during the subsequent press conference, Chair Powell indicated that risks are much more balanced as it pertains to additional tightening, which was a departure from previous meetings where he stated that the risk of doing too little outweighed the risk of doing too much. The dovish sentiment caused interest rates to rally, with the more policy-sensitive 2-year Treasury yield rallying 15 basis points, from 5.09% on October 31, 2023, to 4.94% at the close on November 1, 2023 (the day after the end of this reporting period).

Management Strategies

•  As of October 31, 2023, the Fund had net assets of approximately $46.3 billion. The Fund's weighted average maturity (WAM) and weighted average life (WAL) were 42 days and 91 days, respectively.

•  We continued to manage the portfolio to be responsive to changes in market conditions and interest rate levels. We purchased fixed- and floating-rate U.S. Treasuries for the portfolio and remained focused on portfolio liquidity and conservative positioning while maintaining a competitive return for investors.

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 Fund invests 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. This policy is fundamental and may not be changed without shareholder approval. The Fund may also invest in variable and floating rate demand instruments, tender option bonds, custodial receipts and investments in other investment companies, including money market funds. The Fund may invest up to 20% of its assets in taxable money market securities or in municipal obligations that pay interest income that may be subject to the alternative minimum tax; however, it is currently intended that the Fund will be managed so that income generated by the Fund will not be subject to the alternative minimum tax. In addition, the Fund may temporarily invest more than 20% of its assets in taxable money market securities for defensive purposes in attempting to respond to adverse market conditions, including when suitable municipal obligations are unavailable. When the Fund makes such investments, a higher portion of the Fund's distributions will likely be subject to federal income tax and/or the federal alternative minimum tax. The Fund operates as an "institutional money market fund," which is neither a "government money market fund" nor "retail money market fund" as such terms are defined or interpreted under Rule 2a-7 under the Investment Company Act of 1940, as amended ("Rule 2a-7" under the "1940 Act"). As such, the Fund is required to price and transact in its shares at a net asset value per share ("NAV") reflecting market-based values of its portfolio holdings (i.e., at a "floating" NAV), rounded to a minimum of the fourth decimal place. Like other money market funds of its type, the Fund is subject to the possible imposition of liquidity fees if the Fund's Board of Trustees determines that such fee is in the best interests of the Fund.

Performance

For the fiscal year ended October 31, 2023, the Fund's Institutional Share Class had a total return of 2.95%. For the seven-day period ended October 31, 2023, the Fund's Institutional Share Class provided an annualized current yield of 3.84% (subsidized) and 3.72% (non-subsidized), while its 30-day moving average annualized yield was 3.52% (subsidized) and 3.40% (non-subsidized). Yield quotation

more closely reflects the current earnings of the Fund than the total return. The non-subsidized yield reflects what the yield would have been had a fee and/or expense waiver not been in place during the period shown. Past performance is no guarantee of future results.

Factors Affecting Performance

•  AAA tax-exempt municipal yields generally followed the direction of U.S. Treasury yields over the reporting period. The Bloomberg Municipal Bond Index returned –2.22% for the year-to-date period ended October 31, 2023, continuing negative performance seen during 2022.

•  Like other fixed income asset classes, the municipal bond market experienced an increase in volatility during the reporting period as a result of uncertainty around the Federal Reserve's (Fed) tightening path due to continued persistent inflation, stresses in the banking sector and uncertainty surrounding the U.S. debt ceiling. All these factors resulted in short-term municipal rates moving higher in the reporting period.

•  The Bloomberg Municipal AAA Callable curve remained inverted during the period, pressuring short-term municipal rates. Fund flows in municipal money market funds and resultant supply-demand imbalances contributed to volatility in the Securities Industry and Financial Markets Association (SIFMA) Swap Index. During the reporting period, the SIFMA Swap Index moved as high as 4.47% on August 23, 2023, the highest level since the start of the pandemic in 2020, and as low as 1.66% in late January 2023.⁽ⁱ⁾​ The SIFMA index closed the period at 4.09%.

•  While recent inflation data showed some abatement, uncertainty around the Fed, Treasury market volatility and the geopolitical landscape continued to weigh on the market at the close of the reporting period.

Management Strategies

•  As of October 31, 2023, the Fund had net assets of approximately $475.1 million. The Fund's weighted average maturity (WAM) and weighted average life (WAL) were 15 days and 18 days, respectively.

2023 Annual Report

October 31, 2023

Notes to Financial Statements

Morgan Stanley Institutional Liquidity Funds (the "Trust") is registered under the Investment Company Act of 1940, as amended (the "Act"), as a Massachusetts business trust. The Trust is comprised of seven separate, active, diversified portfolios (individually referred to as a "Fund", collectively as the "Funds"). The Trust offers up to ten different classes of shares for certain Funds. Each Fund offers the Investor Class, Administrative Class, Advisory Class, Participant Class and Cash Management Class; the Institutional Class and Institutional Select Class are only offered to Prime, Government, Government Securities, Treasury, Treasury Securities and Tax-Exempt; the Select Class is only offered to Money Market, Government, Treasury and Treasury Securities Portfolios; the CastleOak Shares Class and Impact Class are only offered to Government and Prime Portfolios and Wealth Class (formerly Institutional Class) and Wealth S Class (formerly Institutional Select Class) are only offered to Money Market Portfolio (formerly ESG Money Market Portfolio). 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.

The Trust applies investment company accounting and reporting guidance Accounting Standards Codification ("ASC") Topic 946. In the preparation of these financial statements, management has evaluated subsequent events occurring after the date of each Fund's Statement of Assets and Liabilities through the date that the financial statements were issued.

During the month of January 2023, CastleOak Shares Class was fully liquidated from Money Market Portfolio and there were no shares outstanding as of October 31, 2023. Accordingly, no financial highlights has been presented for this class.

Prime and Tax-Exempt Portfolios operate as "institutional money market funds," which require these Funds to have a floating NAV, rounded to the fourth decimal place. In July 2023, the Securities and Exchange Commission ("SEC") approved certain regulatory changes that impact money market funds. In particular, among other things, the SEC removed the ability of a money market fund to impose a redemption gate (other than as part of a liquidation), while preserving the discretion to impose liquidity fees for non-government money market funds (without regard to weekly liquid asset levels). These changes became effective on October 2, 2023.

Previously, the Prime Portfolio, Money Market Portfolio and Tax-Exempt Portfolio were permitted to impose a liquidity fee and/or redemption gate if the applicable Fund invested less than 30% of its total assets in weekly liquid assets ("Prior Liquidity Fee and Redemption Gate Framework"). As "government money market funds," the Government Portfolio, Government Securities Portfolio, Treasury Portfolio and

Treasury Securities Portfolio were exempt from the Prior Liquidity Fee and Redemption Gate Framework, but the Board of Trustees reserved its right to opt-in to the Prior Liquidity Fee and Redemption Gate Framework in the future after providing appropriate notice to shareholders. Effective October 2, 2023, the Funds are no longer permitted to temporarily impose a redemption gate, except as part of its liquidation, and each Fund may subject redemptions to a liquidity fee of up to 2% without regard to the Fund's level of weekly liquid assets if the Fund's Board of Trustees believes such fee to be in the best interest of the Fund and its shareholders ("Current Liquidity Fee Framework"). The Government Portfolio, Government Securities Portfolio, Treasury Portfolio and Treasury Securities Portfolio remain exempt from the Current Liquidity Fee Framework, but the Board of Trustees reserves its right to opt-in to the Current Liquidity Fee Framework in the future after providing appropriate notice to shareholders.

For detailed descriptions of the investment objectives of each of the Funds and other related information, please refer to the prospectuses of the Trust. Generally, the investment objective of the Funds 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. Significant Accounting Policies: The following significant accounting policies are in conformity with U.S. generally accepted accounting principles ("GAAP"). Such policies are consistently followed by the Trust in the preparation of its financial statements. GAAP 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: (1) Money Market, Government, Government Securities, Treasury and Treasury Securities: Portfolio securities are valued at amortized cost which approximates fair value, in accordance with Rule 2a-7 under the Act. The amortized cost of an instrument is determined by valuing it at its original cost and thereafter amortizing any discount or premium from its face value at a constant rate until maturity; (2) Prime and Tax-Exempt: Portfolio securities are valued by an outside pricing service/vendor approved by the Trust's Board of Trustees (the "Trustees"). The pricing service/vendor may employ a pricing model that takes into account, among other things, bids, yield spreads and/or other market data and specific security characteristics; and (3) when market quotations are not readily available, as defined by Rule 2a-5 under the Act, including circumstances under which Morgan Stanley Investment Management Inc. (the "Adviser") determines that the price is not reflective of a security's market value, portfolio securities are valued at their fair value as determined in good faith under

77

2023 Annual Report

October 31, 2023

Notes to Financial Statements (cont'd)

procedures approved by and under the general supervision of the Trustees.

In connection with Rule 2a-5 of the Act, the Trustees have designated the Trust's Adviser as its valuation designee. The valuation designee has responsibility for determining fair value and to make the actual calculations pursuant to the fair valuation methodologies previously approved by the Trustees. Under procedures approved by the Trustees, the Trust's Adviser, as valuation designee, has formed a Valuation Committee whose members are approved by the Trustees. The Valuation Committee provides administration and oversight of the Trust's valuation policies and procedures, which are reviewed at least annually by the Trustees. These procedures allow the Trust to utilize independent pricing services, quotations from securities and financial instrument dealers and other market sources to determine fair value.

2.  Repurchase Agreements: Certain Funds may enter into repurchase agreements under which a Fund lends 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 Trust, 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 that the value of the collateral does not decrease below the repurchase price plus accrued interest as earned. If such a decrease occurs, additional collateral will be requested and, when received, will be added to the account to maintain full collateralization. In the event of default on the obligation to repurchase, the Trust 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 of the collateral proceeds may be subject to cost and delays. The Funds, along with other affiliated investment companies, may utilize a joint trading account for the purpose of entering into repurchase agreements.

Certain Funds may enter into repurchase agreements in which eligible securities are transferred into joint trading accounts maintained by the Trust's custodian for investment companies advised by the Trust's Adviser. The Fund will participate on a pro-rata basis with the other investment companies in its share of the securities transferred under such repurchase agreements and in its share of proceeds from any repurchase or other disposition of such securities.

Certain Funds' repurchase agreements are subject to Master Repurchase Agreements which are agreements between the Fund and its counterparties that typically include provisions which provide for the net settlement of all transactions and collateral with the Trust, through a single payment, in the event of default or termination. Amounts presented on the Portfolio of Investments and Statements of Assets and Liabilities are not net settlement amounts but gross. As indicated on the Portfolio of Investments, the cash or securities to be repurchased exceeds the repurchase price to be paid under the repurchase agreement reducing the net settlement amount to zero.

3.  Fair Value Measurement: Financial Accounting Standards Board ("FASB") ASC 820, "Fair Value Measurement" ("ASC 820"), defines fair value as the price that would be received to sell an asset or pay to transfer a liability in an orderly transaction between market partcipants at the measurement date. ASC 820 establishes a three-tier hierarchy to distinguish between (1) inputs that reflect the assumptions market participants would use in valuing an asset or liability developed based on market data obtained from sources independent of the reporting entity (observable inputs) and (2) inputs that reflect the reporting entity's own assumptions about the assumptions market participants would use in valuing an asset or liability developed based on the best information available in the circumstances (unobservable inputs) and to establish classification of fair value measurements for disclosure purposes. Various inputs are used in determining the value of the Trust's investments. The inputs are summarized in the three broad levels listed below:

•  Level 1 – unadjusted quoted prices in active markets for identical investments

•  Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.)

•  Level 3 – significant unobservable inputs including the Fund's own assumptions in determining the fair value of investments. Factors considered in making this determination may include, but are not limited to, information obtained by contacting the issuer, analysts, or the appropriate stock exchange (for exchange-traded securities), analysis of the issuer's financial statements or other available documents and, if necessary, available information concerning other securities in similar circumstances.

Notes to Financial Statements (cont'd)

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities and the determination of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to each security.

The following is a summary of the inputs used to value each Fund's investments as of October 31, 2023:

4.  When-Issued/Delayed Delivery Securities: Certain Funds purchase and sell when-issued and delayed delivery securities. Securities purchased on a when-issued or delayed delivery basis are purchased for delivery beyond the normal settlement date at a stated price and yield, and no income accrues to the Fund on such securities prior to delivery date. Payment and delivery for when-issued and delayed delivery securities can take place a month or more after the date of the transaction. When the Fund enters into a purchase transaction on a when-issued or delayed delivery basis, securities are available for collateral in an amount at least equal in value to the Fund's commitments to purchase such securities. Purchasing securities on a when-issued or delayed delivery basis may involve a risk that the market price at the time of delivery may be lower than the agreed upon purchase price, in which case there could be an unrealized loss at the time of delivery. Purchasing investments on a when-issued or delayed delivery basis may be considered a form of leverage which may increase the impact that gains (losses) may have on the Fund.

5.  Indemnifications: The Trust enters into contracts that contain a variety of indemnification clauses. The Trust's maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Fund that have not yet occurred.

6.  Dividends and Distributions to Shareholders: Dividends are accrued and declared daily and paid monthly. Net realized capital gains, if any, are distributed at least annually.

7.  Security Transactions, Income and Expenses: Security transactions are accounted for on the trade date (date the order to buy or sell is executed). Realized gains and losses on the sale of investment securities are determined on the specific identified cost method. Interest income is recognized on the accrual basis (except where collection is in doubt) net of applicable withholding taxes. Discounts are accreted and premiums are amortized over the life of the respective securities. Most expenses of the Trust can be directly attributed to a particular Fund. Expenses which cannot be directly attributed are apportioned among the Funds based upon relative net assets or other appropriate methods. 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.

B. Advisory Fees: The Adviser, a wholly-owned subsidiary of Morgan Stanley, provides the Trust with advisory services under the terms of an Investment Advisory Agreement, paid

monthly, at the annual rates of the average daily net assets indicated below:

Fund	Advisory Fees
Money Market		0.15	%
Prime		0.15
Government		0.15
Government Securities		0.15
Treasury		0.15
Treasury Securities		0.15
Tax-Exempt		0.15

The Adviser has agreed to reduce its advisory fees, its administration fees and/or reimburse each Fund so that total annual operating expenses of each share class, excluding certain investment related expenses, taxes, interest and other extraordinary expenses (including litigation), will not exceed the maximum expense ratios:

	Maximum Expense Ratios

The fee waivers and/or expense reimbursements will continue for at least one year from the date of the Funds' prospectus or until such time as the Trustees act to discontinue all or a portion of such waivers and/or expense reimbursements when they deem such action is appropriate. In addition, the Adviser may make additional voluntary fee waivers and/or expense reimbursements. The ratio of expenses to average net assets disclosed in the Funds' Financial Highlights may be lower than the maximum expense ratios due to these additional fee waivers and/or expense reimbursements. The Adviser may also

Notes to Financial Statements (cont'd)

waive additional advisory fees and/or reimburse expenses to enable a Fund to maintain a minimum level of daily net investment income. For the year ended October 31, 2023, the Funds had advisory fees waived and/or certain expenses reimbursed as follows:

Fund	Advisory Fees Waived and/or Reimbursed (000)
Money Market	$	1,493
Prime		1,559
Government		69,955
Government Securities		815
Treasury		1,900
Treasury Securities		2,377
Tax-Exempt		598

C. Administration Fees: The Adviser also serves as Administrator to the Trust and provides administrative services pursuant to an Administration Agreement for an annual fee, accrued daily and paid monthly, of 0.05% of each Fund's aver-age daily net assets. Under a Sub-Administration Agreement between the Administrator and State Street Bank and Trust Company ("State Street"), State Street provides certain administrative services to the Trust. For such services, the Administrator pays State Street a portion of the fee the Administrator receives from the Trust.

The Administrator has agreed to reduce its administration fees to enable a Fund to maintain a minimum level of daily net investment income.

For the year ended October 31, 2023, the Fund had administration fees waived as follows:

Fund	Administration Fees Waived (000)
Tax-Exempt	$	45

D. Administration Plan, Service and Shareholder Administration Plan, Distribution Plan and Shareholder Services Plan Fees: Morgan Stanley Distribution, Inc. ("MSDI" or the "Distributor"), a wholly-owned subsidiary of the Adviser, and an indirect subsidiary of Morgan Stanley, serves as the distributor of the Trust.

The Trust has entered into an Administration Plan with respect to its Wealth S Class/ Institutional Select Class, Investor Class and Administrative Class shares pursuant to which each class of shares will pay the Distributor a monthly fee at an annual rate of up to 0.05%, 0.10% and 0.15%, of the average daily net assets of each such class of shares, respectively, to compensate certain financial intermediaries who provide administrative services to shareholders.

The Trust 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 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.

The Trust has also entered into a Distribution Plan with respect to its Participant Class, Cash Management Class and Select Class shares pursuant to which each class of shares will pay the Distributor a monthly distribution fee at an annual rate of up to 0.25%, 0.10% and 0.55% of the average daily net assets of such class of shares, respectively, to compensate certain service organizations for providing distribution related services to the Trust. The Distributor has agreed to waive for at least one year the distribution fee on the Participant Class of the Government Securities Portfolio to the extent it exceeds 0.10% of the average daily net assets on an annualized basis. For the year ended October 31, 2023, this waiver amounted to approximately $7,158,000.

The Trust has also entered into a Shareholder Services Plan with respect to its Participant Class, Cash Management Class and Select Class shares pursuant to which each class of shares will pay the Distributor a monthly service fee at an annual rate of up to 0.25%, 0.05% and 0.25% of the average daily net assets of each such class of shares, respectively, to compensate service organizations for providing administrative services to shareholders. The Distributor has agreed to waive for at least one year the shareholder service fee on the Participant Class of the Government Securities Portfolio to the extent it exceeds 0.15% of the average daily net assets on an annualized basis. For the year ended October 31, 2023, this waiver amounted to approximately $4,771,000.

The Distributor has agreed to reduce its distribution fees to enable a Fund to maintain a minimum level of daily net investment income for any class of shares in a Fund. This arrangement had no effect for the year ended October 31, 2023.

E. Dividend Disbursing and Transfer/Co-Transfer Agent: The Trust's dividend disbursing and transfer agent is SS&C Global Investor & Distribution Solutions, Inc. ("SS&C GIDS, Inc."). Pursuant to a Transfer Agency Agreement, the Trust pays SS&C GIDS, Inc. a fee based on the number of classes, accounts and transactions relating to the Funds of the Trust.

Morgan Stanley Services Company Inc. serves as Co-Transfer Agent and provides certain transfer agency services without compensation to the Trust with respect to certain direct transactions with the Trust.

F. Custodian Fees: State Street (the "Custodian") serves as Custodian for the Trust in accordance with a Custodian Agreement. The Custodian holds cash, securities and other assets of the Trust as required by the Act. Custody fees are

81

2023 Annual Report

October 31, 2023

Notes to Financial Statements (cont'd)

payable monthly based on assets held in custody, investment purchases and sales activity and account maintenance fees, plus reimbursement for certain out-of-pocket expenses.

G. Federal Income Taxes: It is each Fund's intention to continue 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.

FASB ASC 740-10 "Income Taxes — Overall" sets forth a minimum threshold for financial statement recognition of the benefit of a tax position taken or expected to be taken in a tax return. Management has concluded there are no significant uncertain tax positions that would require recognition in the financial statements. If applicable, the Funds recognize interest accrued related to unrecognized tax benefits in "Interest Expense" and penalties in "Other Expenses" in the Statements of Operations. The Funds file tax returns with the U.S. Internal Revenue Service, New York and various states. Each of the tax years in the four-year period ended October 31, 2023 remains subject to examination by taxing authorities.

The tax character of distributions paid may differ from the character of distributions shown for GAAP purposes due to short-term capital gains being treated as ordinary income for tax purposes. The tax character of distributions paid during fiscal years 2023 and 2022 was as follows:

	2023 Distributions Paid From:				2022 Distributions Paid From:
Fund	Ordinary Income (000)		Tax- Exempt Income (000)		Ordinary Income (000)		Tax- Exempt Income (000)
Money Market	$	98,853	$	—	$	35,366	$	—
Prime		819,957		—		147,519		—
Government		6,877,575		—		1,362,663		—
Government Securities		255,531		—		66,898		—
Treasury		1,440,599		—		321,802		—
Treasury Securities		1,940,703		—		389,237		—
Tax-Exempt		282		13,400		31		2,172

The amount and character of income and gains to be distributed are determined in accordance with income tax regulations which may differ from GAAP. These book/tax differences are either considered temporary or permanent in nature.

Temporary differences are primarily due to differing book and tax treatments in the timing of the recognition of distribution payable and/or deferred compensation.

The Funds had no permanent differences causing reclassifications among the components of net assets for the year ended October 31, 2023.

At October 31, 2023, the components of distributable earnings for the Fund on a tax basis were as follows:

Fund	Undistributed Ordinary Income (000)		Tax Exempt Income (000)		Undistributed Long-term Capital Gain (000)
Money Market	$	36	$	—	$	—
Prime		20,683		—		—
Government		312,593		—		—
Government Securities		2,283		—		—
Treasury		64,178		—		—
Treasury Securities		50,902		—		—
Tax-Exempt		—		35		—

At October 31, 2023, the following Funds had available for federal income tax purposes unused short-term and/or long-term capital losses that do not have an expiration date:

Fund	Short-term Losses (No Expiration) (000)		Long-term Losses (No Expiration) (000)
Money Market	$	1,121	$	—
Prime		16,287		—
Government		32,998		249
Government Securities		1,867		—
Treasury		7,364		—
Treasury Securities		10,600		7
Tax-Exempt		2		—

To the extent that capital loss carryforwards are used to offset any future capital gains realized, no capital gains tax liability will be incurred by the Funds for gains realized and not distributed. To the extent that capital gains are offset, such gains will not be distributed to the shareholders.

During the year ended October 31, 2023, the following Funds utilized capital loss carryforwards for U.S. federal income tax purposes of approximately:

Fund	Capital Loss Carryforward Utilized (000)
Money Market	$	22
Prime		183

H. Transactions with Affiliates: The Funds are permitted to purchase and sell securities ("cross-trade") from and to other Morgan Stanley funds as well as other funds and client accounts for which the Adviser or an affiliate of the Adviser serves as investment adviser, pursuant to procedures approved by the Trustees in compliance with Rule 17a-7 under the Act (the "Rule"). Each cross-trade is executed at the current market price in compliance with provisions of the Rule. For the year ended October 31, 2023, Tax-Exempt Portfolio engaged in cross-trade purchases of approximately $3,200,000.

The Trust has an unfunded Deferred Compensation Plan (the "Compensation Plan"), which allows each independent Trustee to defer payment of all, or a portion, of the fees he or she receives for serving on the Board of Trustees. Each eligible

82

2023 Annual Report

October 31, 2023

Notes to Financial Statements (cont'd)

Trustee generally may elect to have the deferred amounts credited with a return equal to the total return on one or more of the Morgan Stanley funds that are offered as investment options under the Compensation Plan. Appreciation/depreciation and distributions received from these investments are recorded with an offsetting increase/decrease in the deferred compensation obligation and do not affect the net asset value of the Funds.

I. Other: At October 31, 2023, certain Funds had otherwise unaffiliated record owners of 10% or greater. Investment activities of these shareholders could have a material impact on these Funds. These Funds and the aggregate percentage of such owners were as follows:

Fund	Percentage of Ownership
Money Market		100.0	%
Prime		49.7
Government		33.6
Government Securities		82.2
Treasury		46.1
Treasury Securities		74.3
Tax-Exempt		95.9

J. Market Risk: An investment in the Fund is based on the values of the Fund's investments, which may change due to economic and other events that affect markets generally, as well as those that affect particular regions, countries, industries, companies or governments. The risks associated with these developments may be magnified if social, political, economic and other conditions and events (such as war, natural disasters, health emergencies (e.g., epidemics and pandemics), terrorism, conflicts, social unrest, recessions, inflation, rapid interest rate changes and supply chain disruptions) adversely interrupt the global economy and financial markets. It is difficult to predict when events affecting the U.S. or global financial markets may occur, the effects that such events may have and the duration of those effects (which may last for extended periods). These events may negatively impact broad segments of businesses and populations and have a significant and rapid negative impact on the performance of the Fund's investments, adversely affect and increase the volatility of the Fund's share price and exacerbate pre-existing risks to the Fund. The occurrence, duration and extent of these or other types of adverse economic and market conditions and uncertainty over the long term cannot be reasonably projected or estimated at this time. The ultimate impact of public health emergencies or other adverse economic or market developments and the extent to which the associated conditions impact the Fund and its investments will also depend on other future developments, which are highly uncertain, difficult to accurately predict and subject to change at any time. The financial performance of the Fund's investments (and, in turn, the Fund's investment results) as well as their

liquidity may be adversely affected because of these and similar types of factors and developments.

K. LIBOR Discontinuance or Unavailability Risk: The London Interbank Offering Rate ("LIBOR") was a leading floating rate benchmark used in loans, notes, derivatives and other instruments or investments. As a result of benchmark reforms, publication of most LIBOR settings has ceased. Some LIBOR settings continue to be published but only on a temporary, synthetic and non-representative basis. Regulated entities have generally ceased entering into new LIBOR contracts in connection with regulatory guidance or prohibitions. Public and private sector actors have worked to establish new or alternative reference rates to be used in place of LIBOR. Certain loans, notes, derivatives, and other instruments or investments held by the Fund may be impacted by the foregoing. There is no assurance that the composition or characteristics of any such new or alternative reference rate will be similar to or produce the same value or economic equivalence as LIBOR or that it will have the same volume or liquidity as did LIBOR, which may affect the value or liquidity or return on certain of the Fund's investments and result in costs incurred in connection with closing out positions and entering into new trades.

Neither the effect of the LIBOR transition process nor its ultimate success can yet be known. The transition process might lead to increased volatility and illiquidity in markets for, and reduce the effectiveness of hedges placed against, instruments whose terms currently include (or previously included) LIBOR. While some LIBOR-based instruments contemplated a scenario where LIBOR is no longer available by providing for an alternative rate-setting methodology, there may be significant uncertainty regarding the effectiveness of any such alternative methodologies to replicate or replace LIBOR. Some of the Fund's investments may be so-called "tough legacy" LIBOR instruments which may not have effective alternative rate-setting provisions or may involve counterparties who are unwilling to add or exercise rights under alternative rate-setting provisions in such instruments. On March 15, 2022, the Adjustable Interest Rate (LIBOR) Act was signed into law. This law provides a statutory fallback mechanism on a nationwide basis to replace U.S. Dollar LIBOR with a benchmark rate that is selected by the Board of Governors of the Federal Reserve System based on the Secured Overnight Financing Rate ("SOFR") for tough legacy contracts. On February 27, 2023, the final rule in connection with this law became effective, establishing benchmark replacements based on SOFR and Term SOFR (a forward-looking measurement of market expectations of SOFR implied from certain derivatives markets) for applicable tough legacy contracts governed by U.S. law. In addition, the FCA has announced that it will require the publication of

83

2023 Annual Report

October 31, 2023

Notes to Financial Statements (cont'd)

the one-month, three-month and six-month U.S. Dollar LIBOR settings on the basis of a changed methodology (known as "synthetic LIBOR"), after June 30, 2023 through at least September 30, 2024, addressing non-U.S. law governed U.S. Dollar LIBOR instruments, but this synthetic LIBOR will be designated by the FCA as unrepresentative of the underlying market that it seeks to measure and will be solely available for use in legacy transactions. The transition of investments from LIBOR to a new or replacement rate as a result of amendment, application of existing fallbacks, statutory requirements, the application of synthetic LIBOR or otherwise may also result in a reduction in the value of certain instruments held by the Fund or a reduction in the effectiveness of related Fund transactions such as hedges. In addition, a liquid market for newly-issued instruments that use a reference rate other than LIBOR is still developing. There may also be challenges for the Fund to enter into hedging transactions against such newly-issued instruments until a market for such hedging transactions more fully develops. All of the aforementioned may adversely affect the Fund's investments (including their volatility, value and liquidity) and, as a result, the performance or NAV.

L. Subsequent Event: Effective on or about February 29, 2024, the Tax-Exempt Portfolio will operate as a "retail money market fund," as defined in Rule 2a-7 under the 1940 Act. A "retail money market fund" is defined as a money market fund that has policies and procedures reasonably designed to limit all beneficial owners of the fund to natural persons. As a result, investments in the Fund will be limited to shareholder accounts beneficially owned by natural persons.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Trustees of
Morgan Stanley Institutional Liquidity Funds:

Opinion on the Financial Statements

We have audited the accompanying statements of assets and liabilities of Morgan Stanley Institutional Liquidity Funds (the "Trust") (comprising, Money Market Portfolio (formerly ESG Money Market Portfolio), Prime Portfolio, Government Portfolio, Government Securities Portfolio, Treasury Portfolio, Treasury Securities Portfolio, and Tax-Exempt Portfolio) (collectively referred to as the "Funds"), including the portfolios of investments, as of October 31, 2023, and the related statements of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, the financial highlights for each of the five years in the period then ended and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of each of the Funds comprising Morgan Stanley Institutional Liquidity Funds at October 31, 2023, the results of their operations for the year then ended, the changes in their net assets for each of the two years in the period then ended and their financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements are the responsibility of the Trust's management. Our responsibility is to express an opinion on the Funds' financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Trust in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Trust is not required to have, nor were we engaged to perform, an audit of the Trust's internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of October 31, 2023, by correspondence with the custodian, brokers and others; when replies were not received from brokers and others, we performed other auditing procedures. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as the auditor of one or more Morgan Stanley investment companies since 2000.

Investment Advisory Agreement Approval (unaudited)

Nature, Extent and Quality of Services

The Board reviewed and considered the nature and extent of the investment advisory services provided by the Adviser under the advisory agreement, including portfolio management, investment research and equity and fixed income securities trading. The Board also reviewed and considered the nature and extent of the non-advisory, administrative services provided by the Administrator under the administration agreement, including accounting, operations, clerical, bookkeeping, compliance, business management and planning, legal services and the provision of supplies, office space and utilities at the Adviser's expense. The Board also considered the Adviser's investment in personnel and infrastructure that benefits the Funds. (The Adviser and Administrator together are referred to as the "Adviser" and the advisory and administration agreements together are referred to as the "Management Agreement.") The Board also considered that the Adviser serves a variety of other investment advisory clients and has experience overseeing service providers. The Board also compared the nature of the services provided by the Adviser with similar services provided by non-affiliated advisers as prepared by Broadridge Financial Solutions, Inc. ("Broadridge").

The Board reviewed and considered the qualifications of the portfolio managers, the senior administrative managers and other key personnel of the Adviser who provide the advisory and administrative services to the Funds. The Board determined that the Adviser's portfolio managers and key personnel are well qualified by education and/or training and experience to perform the services in an efficient and professional manner. The Board concluded that the nature and extent of the advisory and administrative services provided were necessary and appropriate for the conduct of the business and investment activities of the Funds and supported its decision to approve the Management Agreement.

Performance, Fees and Expenses of the Funds

The Board reviewed the performance, fees and expenses of the Funds compared to their peers, as prepared by Broadridge, and to appropriate benchmarks where applicable. The Board discussed with the Adviser the performance goals and the actual results achieved in managing the Funds. When considering a fund's performance, the Board and the Adviser place emphasis on trends and longer-term returns (focusing on one-year, three-year and five-year performance, as of December 31, 2022, or since inception, as applicable). When a fund underperforms its benchmark and/or its peer group average, the Board and the Adviser discuss the causes of such underperformance and, where necessary, they discuss specific changes to investment strategy or investment personnel.

Performance

The Board noted that the performances of the Money Market (f/k/a ESG Money Market Portfolio), Prime, Government, Government Securities, Tax-Exempt, Treasury and Treasury Securities Portfolios were better than their peer group averages for the one-, three- and five-year periods.

Performance Conclusions

With respect to all of the Funds, after discussion, the Board concluded that performance was competitive with their peer group averages.

Fees and Expenses

The Board discussed with the Adviser the level of the advisory and administration fees (together, the "management fee") for the Funds relative to comparable funds and/or other accounts advised by the Adviser and/or compared to their peers as prepared by Broadridge. In addition to the management fee, the Board also reviewed the Funds' total expense ratios. When a fund's management fee and/or its total expense ratio are higher than its peers, the Board and the Adviser discuss the reasons for this and, where appropriate, they discuss possible waivers and/or caps.

The Board noted that, for the Money Market and Government Portfolios, the management fee and total expense ratio were higher than their peer group averages.

The Board noted that, for the Prime Portfolio, the management fee was higher than but close to its peer group average and the total expense ratio was lower than its peer group average.

The Board noted that, for the Government Securities Portfolio, the contractual management fee was lower than its peer group average and the actual management fee and total expense ratio were higher than its peer group averages.

86

2023 Annual Report

October 31, 2023

Investment Advisory Agreement Approval (unaudited) (cont'd)

The Board noted that, for the Tax-Exempt Portfolio, the management fee was lower than its peer group average and the total expense ratio was higher than its peer group average.

The Board noted that, for the Treasury and Treasury Securities Portfolios, the contractual management fee was higher than but close to their peer group averages and the actual management fee and the total expense ratio were higher than their peer group averages.

Fee and Expense Conclusion

With respect to Prime Portfolio, after discussion, the Board concluded that the management fee and total expense ratio were competitive with its peer group averages.

With respect to Tax-Exempt Portfolio, after discussion, the Board concluded that the management fee was competitive with its peer group average and the total expense ratio was acceptable.

With respect to, the Money Market, Government, Government Securities, Treasury and Treasury Securities Portfolios, after discussion, the Board concluded that the management fees and total expense ratios were acceptable.

Economies of Scale

The Board considered the size and growth prospects of the Funds and how that relates to the Funds' total expense ratios and particularly the Funds' management fee rates (which for all the Funds do not include breakpoints). In conjunction with its review of the Adviser's profitability, the Board discussed with the Adviser how a change in assets can affect the efficiency or effectiveness of managing the Funds and whether the management fee level is appropriate relative to current and projected asset levels and/or whether the management fee structure reflects economies of scale as asset levels change. The Board has determined that its review of the actual and/or potential economies of scale of each Fund supports its decision to approve the Management Agreement.

Profitability of the Adviser and Affiliates

The Board considered information concerning the costs incurred and profits realized by the Adviser and its affiliates during the last year from their relationship with the Funds and during the last two years from their relationship with the Morgan Stanley Fund Complex and reviewed with the Adviser the cost allocation methodology used to determine the profitability of the Adviser and affiliates. The Board has determined that its review of the analysis of the Adviser's expenses and profitability supports its decision to approve the Management Agreement.

Other Benefits of the Relationship

The Board considered other direct and indirect benefits to the Adviser and/or its affiliates derived from their relationship with the Funds and other funds advised by the Adviser. These benefits may include, among other things, fees for trading, distribution and/or shareholder servicing and for transaction processing and reporting platforms used by securities lending agents, and research received by the Adviser generated from commission dollars spent on funds' portfolio trading. The Board reviewed with the Adviser these arrangements and the reasonableness of the Adviser's costs relative to the services performed. The Board has determined that its review of the other benefits received by the Adviser or its affiliates supports its decision to approve the Management Agreement.

Resources of the Adviser and Historical Relationship Between the Funds and the Adviser

The Board considered whether the Adviser is financially sound and has the resources necessary to perform its obligations under the Management Agreement. The Board also reviewed and considered the historical relationship between the Funds and the Adviser, including the organizational structure of the Adviser, the policies and procedures formulated and adopted by the Adviser for managing the Funds' operations and the Board's confidence in the competence and integrity of the senior managers and key personnel of the Adviser. The Board concluded that the Adviser has the financial resources necessary to fulfill its obligations under the Management Agreement and that it is beneficial for the Funds to continue their relationship with the Adviser.

Other Factors and Current Trends

The Board considered the controls and procedures adopted and implemented by the Adviser and monitored by the Funds' Chief Compliance Officer and concluded that the conduct of business by the Adviser indicates a good faith effort on its part to adhere to high ethical standards in the conduct of the Funds' business.

General Conclusion

After considering and weighing all of the above factors, with various written materials and verbal information presented by the Adviser, the Board concluded that it would be in the best interest of each Fund and its shareholders to approve renewal of the Management Agreement for another year. In reaching this conclusion the Board did not give particular weight to any single piece of information or factor referenced above. The Board considered these factors and information over the course of the year and in numerous meetings, some of which were in executive session with only the independent Board members and their counsel present. It is possible that individual Board members may have weighed these factors, and the information presented, differently in reaching their individual decisions to approve the Management Agreement.

(e)(1) The audit committee’s pre-approval policies and procedures are as follows:

AUDIT COMMITTEE
AUDIT AND NON-AUDIT SERVICES
PRE-APPROVAL POLICY AND PROCEDURES
OF THE
MORGAN STANLEY FUNDS

AS ADOPTED AND AMENDED JULY 23, 2004 AND JUNE 12 AND 13, 2019³

 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.

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.

³ 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.

 2. 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.

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

 4. 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 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-CEN and/or N-CSR.

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

 5. 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 A. All Tax services in Appendix A must be specifically pre-approved by the Audit Committee (or by any member of the Audit Committee to which pre-approval has been delegated).

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

 7. 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.

 8. 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 Principal Financial and Accounting Officer and must include a detailed description of the services to be rendered. The Fund’s Principal Financial and Accounting 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 or Chairperson of the Audit Committee will be submitted to the Audit Committee by the Fund’s Principal Financial and Accounting Officer, who, after consultation with the Independent Auditors, will discuss whether the request or application is consistent with the SEC’s rules on auditor independence.

The Audit Committee has designated the Fund’s Principal Financial and Accounting 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 Principal Financial and Accounting Officer will report to the Audit Committee on a periodic basis on the results of its monitoring. Both the Fund’s Principal Financial and Accounting Officer and management will immediately report to the Chairperson of the Audit Committee any breach of this Policy that comes to the attention of the Fund’s Principal Financial and Accounting Officer or any member of management.

 9. 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 the PCAOB’s Ethics and Independence Rule 3526, and discussing with the Independent Auditors its methods and procedures for ensuring independence.

 10. 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 Funds

 Morgan Stanley & Co. LLC

 Morgan Stanley Investment Management Inc.

 Morgan Stanley Investment Management Limited

 Morgan Stanley Investment Management Private Limited

 Morgan Stanley Asset & Investment Trust Management Co., Limited

 Morgan Stanley Investment Management Company

 Morgan Stanley Services Company, Inc.

 Morgan Stanley Distribution, Inc.

 Morgan Stanley AIP GP LP

 Morgan Stanley Alternative Investment Partners LP

 Morgan Stanley Smith Barney LLC

 Morgan Stanley Capital Management LLC

 Morgan Stanley Asia Limited

 Morgan Stanley Services Group

(e)(2) Beginning with non-audit service contracts entered into on or after May 6, 2003, the audit committee also is required to pre-approve services to Covered Entities to the extent that the services are determined to have a direct impact on the operations or financial reporting of the Registrant. 100% of such services were pre-approved by the audit committee pursuant to the Audit Committee’s pre-approval policies and procedures (attached hereto).

(f) Not applicable.

(g) See table above.

(h) The audit committee of the Board of Trustees has considered whether the provision of services other than audit services performed by the auditors to the Registrant and Covered Entities is compatible with maintaining the auditors' independence in performing audit services.
