Western Asset Institutional Liquid Reserves 2026 Semi-Annual Report
Notes to Financial Statements (unaudited)
1. Organization and significant accounting policies
Western Asset Institutional Liquid Reserves (the "Fund") is a separate diversified investment series of Legg Mason Partners Institutional Trust (the "Trust"). The Trust, a Maryland statutory trust, is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end management investment company. The Fund invests all of its investable assets in Liquid Reserves Portfolio (the "Portfolio"), a separate investment series of Master Portfolio Trust, that has the same investment objective as the Fund.
The financial statements of the Portfolio, including the schedule of investments, are contained elsewhere in this report and should be read in conjunction with the Fund's financial statements.
The share price of the Fund fluctuates along with changes in the market-based value of fund assets. Because the share price of the Fund fluctuates, it has what is called a "floating net asset value" or "floating NAV". Under Rule 2a-7 of the 1940 Act, the Fund must follow strict rules as to the credit quality, liquidity, diversification and maturity of its investments.
The Fund follows the accounting and reporting guidance in Financial Accounting Standards Board ("FASB") Accounting Standards Codification Topic 946, Financial Services - Investment Companies("ASC 946"). The following are significant accounting policies consistently followed by the Fund and are in conformity with U.S. generally accepted accounting principles ("GAAP"), including, but not limited to, ASC 946. Estimates and assumptions are required to be made regarding assets, liabilities and changes in net assets resulting from operations when financial statements are prepared. Changes in the economic environment, financial markets and any other parameters used in determining these estimates could cause actual results to differ. Subsequent events have been evaluated through the date the financial statements were issued.
(a) Investment valuation. The Fund records its investment in the Portfolio at value. The value of such investment in the Portfolio reflects the Fund's proportionate interest (5.6% at February 28, 2026) in the net assets of the Portfolio.
GAAP establishes a disclosure hierarchy that categorizes the inputs to valuation techniques used to value assets and liabilities at measurement date. The disclosure and valuation of securities held by the Portfolio are discussed in Note 1(a) of the Portfolio's Notes to Financial Statements, which are included elsewhere in this report.
(b) Investment transactions and investment income. Net investment income and net realized/unrealized gains and losses of the Portfolio is allocated pro rata, based on respective ownership interests, among the Fund and other investors in the Portfolio (the "Holders") at the time of such determination. The Fund also pays certain other expenses which can be directly attributed to the Fund.
Western Asset Institutional Liquid Reserves 2026 Semi-Annual Report
6
Notes to Financial Statements (unaudited) (cont'd)
(c) Distributions to shareholders. Distributions from net investment income on the shares of the Fund are declared each business day and are paid monthly. Distributions of net realized gains, if any, are declared at least annually. Distributions to shareholders of the Fund are recorded on the ex-dividend date and are determined in accordance with income tax regulations, which may differ from GAAP.
(d) Share class accounting. Investment income, common expenses and realized/unrealized gains (losses) on investments are allocated to the various classes of the Fund on the basis of daily net assets of each class. Fees relating to a specific class are charged directly to that share class.
(e) Federal and other taxes. It is the Fund's policy to comply with the federal income and excise tax requirements of the Internal Revenue Code of 1986 (the "Code"), as amended, applicable to regulated investment companies. Accordingly, the Fund intends to distribute its taxable income and net realized gains, if any, to shareholders in accordance with timing requirements imposed by the Code. Therefore, no federal or state income tax provision is required in the Fund's financial statements.
Management has analyzed the Fund's tax positions taken on income tax returns for all open tax years and has concluded that as of August 31, 2025, no provision for income tax is required in the Fund's financial statements. The Fund's federal and state income and federal excise tax returns for the prior three fiscal years are subject to examination by the Internal Revenue Service and state departments of revenue.
(f) Reclassification. GAAP requires that certain components of net assets be reclassified to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or net asset value per share.
2. Investment management agreement and other transactions with affiliates
Franklin Templeton Fund Adviser, LLC ("FTFA") is the Fund's and the Portfolio's investment manager and Western Asset Management Company, LLC ("Western Asset") is the Fund's and the Portfolio's subadviser. FTFA and Western Asset are indirect, wholly-owned subsidiaries of Franklin Resources, Inc. ("Franklin Resources").
Under the investment management agreement, the Fund pays an investment management fee, calculated daily and paid monthly, in accordance with the following breakpoint schedule:
 
Average Daily Net Assets
Annual Rate
First $5 billion
0.200
%
Next $5 billion
0.175
Over $10 billion
0.150
7
Western Asset Institutional Liquid Reserves 2026 Semi-Annual Report
Since the Fund invests all of its investable assets in the Portfolio, the investment management fee of the Fund will be reduced by the investment management fee allocated to the Fund by the Portfolio.
FTFA provides administrative and certain oversight services to the Fund. FTFA delegates to the subadviser the day-to-day portfolio management of the Fund. For its services, FTFA pays Western Asset a fee monthly, at an annual rate equal to 70% of the net management fee it receives from the Fund.
As a result of expense limitation arrangements between the Fund and FTFA, the ratio of total annual fund operating expenses, other than interest, brokerage, taxes, extraordinary expenses and acquired fund fees and expenses, to average net assets of Institutional Shares and Investor Shares did not exceed 0.18% and 0.23%, respectively. These expense limitation arrangements cannot be terminated prior to December 31, 2026 without the Board of Trustees' (the "Board") consent. Additional amounts may be voluntarily waived and/or reimbursed from time to time.
During the six months ended February 28, 2026, fees waived and/or expenses reimbursed amounted to $292,767.
FTFA is permitted to recapture amounts waived and/or reimbursed to a class during the same fiscal year if the class' total annual fund operating expenses have fallen to a level below the expense limitation ("expense cap") in effect at the time the fees were earned or the expenses incurred. In no case will FTFA recapture any amount that would result, on any particular business day of the Fund, in the class' total annual fund operating expenses exceeding the expense cap or any other lower limit then in effect.
Franklin Distributors, LLC ("Franklin Distributors") serves as the Fund's sole and exclusive distributor. Franklin Distributors is an indirect, wholly-owned broker-dealer subsidiary of Franklin Resources.
All officers and one Trustee of the Trust are employees of Franklin Resources or its affiliates and do not receive compensation from the Trust.
3. Class specific expenses, waivers and/or expense reimbursements
The Fund has adopted a Rule 12b-1 shareholder services and distribution plan and under that plan the Fund pays service and/or distribution fees with respect to its Investor Shares calculated at the annual rate not to exceed 0.10% of the average daily net assets. Service and/or distribution fees are accrued daily and paid monthly.

5. Shares of beneficial interest
At February 28, 2026, the Trust had an unlimited number of shares of beneficial interest authorized with a par value of $0.00001 per share.

Liquid Reserves Portfolio 2026 Semi-Annual Report

Notes to Financial Statements (unaudited)
1. Organization and significant accounting policies
Liquid Reserves Portfolio (the "Portfolio") is a separate diversified investment series of Master Portfolio Trust (the "Trust"). The Trust, a Maryland statutory trust, is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end management investment company. The Declaration of Trust permits the Board of Trustees (the "Board") to issue beneficial interests in the Portfolio. At February 28, 2026, all investors in the Portfolio were funds advised or administered by the investment manager of the Portfolio and/or its affiliates.
The Portfolio sells and effects withdrawals of its interests at prices based on the current market value of the securities it holds. Therefore, the price of an interest in the Portfolio fluctuates along with changes in the market-based value of the holdings of the Portfolio. Because the price of an interest in the Portfolio fluctuates, it has what is called a "floating net asset value" or "floating NAV". Under Rule 2a-7 of the 1940 Act ("Rule 2a-7"), the Portfolio must follow strict rules as to the credit quality, liquidity, diversification and maturity of its investments.
The Portfolio follows the accounting and reporting guidance in Financial Accounting Standards Board ("FASB") Accounting Standards Codification Topic 946, Financial Services - Investment Companies ("ASC 946"). The following are significant accounting policies consistently followed by the Portfolio and are in conformity with U.S. generally accepted accounting principles ("GAAP"), including, but not limited to, ASC 946. Estimates and assumptions are required to be made regarding assets, liabilities and changes in net assets resulting from operations when financial statements are prepared. Changes in the economic environment, financial markets and any other parameters used in determining these estimates could cause actual results to differ. Subsequent events have been evaluated through the date the financial statements were issued.
(a) Investment valuation. The valuations for fixed income securities (which may include, but are not limited to, corporate, government, municipal, mortgage-backed, collateralized mortgage obligations and asset-backed securities) are typically the prices supplied by independent third party pricing services, which may use market prices or broker/dealer quotations or a variety of valuation techniques and methodologies. The independent third party pricing services typically use inputs that are observable such as issuer details, interest rates, yield curves, prepayment speeds, credit risks/spreads, default rates and quoted prices for similar securities. When the Portfolio holds securities or other assets that are denominated in a foreign currency, the Portfolio will normally use the currency exchange rates as of 4:00 p.m. (Eastern Time). If independent third party pricing services are unable to supply prices for a portfolio investment, or if the prices supplied are deemed by the manager to be unreliable, the market price may be determined by the manager using quotations from one or more broker/dealers or at the transaction price if the security has recently been purchased and no value has yet been obtained from a pricing service or pricing broker. When reliable prices are not readily available, such as when the value of a
21
Liquid Reserves Portfolio 2026 Semi-Annual Report
security has been significantly affected by events after the close of the exchange or market on which the security is principally traded, but before the Portfolio calculates its net asset value, the Portfolio values these securities as determined in accordance with procedures approved by the Board.
Pursuant to policies adopted by the Board, the Portfolio's manager has been designated as the valuation designee and is responsible for the oversight of the daily valuation process. The Portfolio's manager is assisted by the Global Fund Valuation Committee (the "Valuation Committee"). The Valuation Committee is responsible for making fair value determinations, evaluating the effectiveness of the Portfolio's pricing policies, and reporting to the Portfolio's manager and the Board. When determining the reliability of third party pricing information for investments owned by the Portfolio, the Valuation Committee, among other things, conducts due diligence reviews of pricing vendors, monitors the daily change in prices and reviews transactions among market participants.
The Valuation Committee will consider pricing methodologies it deems relevant and appropriate when making fair value determinations. Examples of possible methodologies include, but are not limited to, multiple of earnings; discount from market of a similar freely traded security; discounted cash-flow analysis; book value or a multiple thereof; risk premium/yield analysis; yield to maturity; and/or fundamental investment analysis. The Valuation Committee will also consider factors it deems relevant and appropriate in light of the facts and circumstances. Examples of possible factors include, but are not limited to, the type of security; the issuer's financial statements; the purchase price of the security; the discount from market value of unrestricted securities of the same class at the time of purchase; analysts' research and observations from financial institutions; information regarding any transactions or offers with respect to the security; the existence of merger proposals or tender offers affecting the security; the price and extent of public trading in similar securities of the issuer or comparable companies; and the existence of a shelf registration for restricted securities.
For each portfolio security that has been fair valued pursuant to the policies adopted by the Board, the fair value price is compared against the last available and next available market quotations. The Valuation Committee reviews the results of such back testing monthly and fair valuation occurrences are reported to the Board quarterly.
The Portfolio uses valuation techniques to measure fair value that are consistent with the market approach and/or income approach, depending on the type of security and the particular circumstance. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable securities. The income approach uses valuation techniques to discount estimated future cash flows to present value.

Notes to Financial Statements (unaudited) (cont'd)
GAAP establishes a disclosure hierarchy that categorizes the inputs to valuation techniques used to value assets and liabilities at measurement date. These 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 Portfolio's own assumptions in determining the fair value of investments)
The inputs or methodologies used to value securities are not necessarily an indication of the risk associated with investing in those securities.
The following is a summary of the inputs used in valuing the Portfolio's assets carried at fair value:

(b) Repurchase agreements. The Portfolio may enter into repurchase agreements with institutions that its subadviser has determined are creditworthy. Each repurchase agreement is recorded at cost. Under the terms of a typical repurchase agreement, the Portfolio acquires a debt security subject to an obligation of the seller to repurchase, and of the Portfolio to resell, the security at an agreed-upon price and time, thereby determining the yield during the Portfolio's holding period. When entering into repurchase agreements, it is the Portfolio's policy that its custodian or a third party custodian, acting on the Portfolio's behalf, take possession of the underlying collateral securities, the market value of which, at all times, at least equals the principal amount of the repurchase transaction, including accrued interest. To the extent that any repurchase transaction maturity exceeds one business day, the value of the collateral is marked-to-market and measured against the value of the agreement in an effort to ensure the adequacy of the collateral. If the counterparty defaults, the Portfolio generally has the right to use the collateral to satisfy the terms of the repurchase transaction. However, if the market value of the collateral declines during the period in which the Portfolio seeks to assert its rights or if bankruptcy proceedings are commenced with respect to the seller of the security, realization of the collateral by the Portfolio may be delayed or limited.
(c) Interest income and expenses. Interest income (including interest income from payment-in-kind securities) consists of interest accrued and discount earned (including both
23
Liquid Reserves Portfolio 2026 Semi-Annual Report
original issue and market discount adjusted for amortization of premium) on the investments of the Portfolio. Expenses of the Portfolio are accrued daily. The Portfolio bears all costs of its operations other than expenses specifically assumed by the manager.
(d) Method of allocation. Net investment income and net realized/unrealized gains and/or losses of the Portfolio are allocated pro rata, based on respective ownership interests, among the Fund and other investors in the Portfolio (the "Holders") at the time of such determination.
(e) Credit and market risk. Investments in securities that are collateralized by real estate mortgages are subject to certain credit and liquidity risks. When market conditions result in an increase in default rates of the underlying mortgages and the foreclosure values of underlying real estate properties are materially below the outstanding amount of these underlying mortgages, collection of the full amount of accrued interest and principal on these investments may be doubtful. Such market conditions may significantly impair the value and liquidity of these investments and may result in a lack of correlation between their credit ratings and values.
(f) Income taxes. The Portfolio is classified as a partnership for federal income tax purposes. As such, each investor in the Portfolio is treated as owner of its proportionate share of the net assets, income, expenses and realized and unrealized gains and losses of the Portfolio. Therefore, no federal income tax provision is required. It is intended that the Portfolio's assets will be managed so an investor in the Portfolio can satisfy the requirements of Subchapter M of the Internal Revenue Code.
Management has analyzed the Portfolio's tax positions taken on income tax returns for all open tax years and has concluded that as of August 31, 2025, no provision for income tax is required in the Portfolio's financial statements. The Portfolio's federal and state income tax returns for the prior three fiscal years are subject to examination by the Internal Revenue Service and state departments of revenue.
(g) Other. Purchases, maturities and sales of money market instruments are accounted for on the date of the transaction. Realized gains and losses are calculated on the identified cost basis.
2. Investment management agreement and other transactions with affiliates
Franklin Templeton Fund Adviser, LLC ("FTFA") is the Portfolio's investment manager and Western Asset Management Company, LLC ("Western Asset") is the Portfolio's subadviser. FTFA and Western Asset are indirect, wholly-owned subsidiaries of Franklin Resources, Inc. ("Franklin Resources").
Under the investment management agreement, the Portfolio pays an investment management fee, calculated daily and paid monthly, at an annual rate of 0.10% of the Portfolio's average daily net assets.
Liquid Reserves Portfolio 2026 Semi-Annual Report
24
Notes to Financial Statements (unaudited) (cont'd)
FTFA provides administrative and certain oversight services to the Portfolio. FTFA delegates to the subadviser the day-to-day portfolio management of the Portfolio. For its services, FTFA pays Western Asset a fee monthly, at an annual rate equal to 70% of the net management fee it receives from the Portfolio.
As a result of the investment management agreement between FTFA and the feeder fund, FTFA has agreed to waive 0.10% of Portfolio expenses, attributable to the Portfolio's investment management fee. Additional amounts may be voluntarily waived and/or reimbursed from time to time.
During the six months ended February 28, 2026, fees waived and/or expenses reimbursed amounted to $3,822,146.
FTFA is permitted to recapture amounts waived and/or reimbursed to the Portfolio during the same fiscal year under certain circumstances.
All officers and one Trustee of the Trust are employees of Franklin Resources or its affiliates and do not receive compensation from the Trust.
3. Investments

4. Derivative instruments and hedging activities

5. Operating segments
The Portfolio operates as a single operating segment, which is an investment portfolio. A management group assigned to the Portfolio within the Portfolio's investment manager serves as the Chief Operating Decision Maker ("CODM") and is responsible for evaluating the Portfolio's operating results and allocating resources in accordance with the Portfolio's investment strategy. Internal reporting provided to the CODM aligns with the accounting policies and measurement principles used in the financial statements.
For information regarding segment assets, segment profit or loss, and significant expenses, refer to the Statement of Assets and Liabilities and the Statement of Operations, along with the related Notes to Financial Statements.
