If the Fund is a seller of protection and a credit event occurs, as defined under the terms of that particular swap
agreement, the Fund will either (i) pay to the buyer of protection an amount equal to the notional amount of the
swap and take delivery of the referenced obligation or underlying securities comprising the referenced index or (ii)
pay a net settlement amount in the form of cash or securities equal to the notional amount of the swap less the
recovery value of the referenced obligation or underlying securities comprising the referenced index.
2
The maximum potential amount the Fund could be required to pay as a seller of credit protection or receive as a
buyer of credit protection if a credit event occurs as defined under the terms of that particular swap agreement.
3
The quoted market prices and resulting values for credit default swap agreements on asset-backed securities and
credit indices serve as an indicator of the current status of the payment/performance risk and represent the
likelihood of an expected loss (or profit) for the credit derivative had the notional amount of the swap agreement
been closed/sold as of the period end. Decreasing market values (sell protection) or increasing market values (buy
protection), when compared to the notional amount of the swap, represent a deterioration of the referenced
entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under
the terms of the agreement.
Percentage shown is an annual percentage rate.

1. Organization and significant accounting policies
Western Asset SMASh Series M Fund (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.
Shares of the Fund may be purchased only by or on behalf of separately managed account clients where an affiliate of Franklin Templeton Fund Adviser, LLC (“FTFA”) has an agreement to serve as investment adviser or subadviser (each affiliate, a “Managed Account Adviser”) to the account with the managed account program sponsor (the “Program Sponsor”) (typically, a registered investment adviser or broker/dealer) or directly with the client. Shareholders of the Fund pay fees to their separately managed account sponsor, some of which are paid to affiliates of FTFA. FTFA and the subadvisers do not charge investment management fees to the Fund.
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 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) and certain derivative instruments 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. Investments in open-end funds are valued at the closing net asset value per share of each fund on the day of valuation. Futures contracts are valued daily at the settlement price established by the board of trade or exchange on which they are traded. Equity securities for which market quotations are available are valued at the last reported sales price or official closing price on the primary market or exchange on which they trade. When the Fund holds securities or other assets that are denominated in a foreign currency, the Fund 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

22
Western Asset SMASh Series M Fund 2024 Semi-Annual Report

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 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 Fund calculates its net asset value, the Fund values these securities as determined in accordance with procedures approved by the Fund’s Board of Trustees.  
Pursuant to policies adopted by the Board of Trustees, the Fund’s manager has been designated as the valuation designee and is responsible for the oversight of the daily valuation process. The Fund’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 Fund’s pricing policies, and reporting to the Fund’s manager and the Board of Trustees. When determining the reliability of third party pricing information for investments owned by the Fund, 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 of Trustees, 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 of Trustees quarterly.
The Fund 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
Western Asset SMASh Series M Fund 2024 Semi-Annual Report

23

Notes to Financial Statements (unaudited) (cont’d)
generated by market transactions involving identical or comparable securities. The income approach uses valuation techniques to discount estimated future cash flows to present value.
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 Fund’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 Fund’s assets and liabilities carried at fair value:

(b) Futures contracts.The Fund uses futures contracts generally to gain exposure to, or hedge against, changes in interest rates or gain exposure to, or hedge against, changes in certain asset classes. A futures contract represents a commitment for the future purchase or sale of an asset at a specified price on a specified date.
Upon entering into a futures contract, the Fund is required to deposit cash or securities with a broker in an amount equal to a certain percentage of the contract amount. This is known as the ‘‘initial margin’’ and subsequent payments (‘‘variation margin’’) are made or received by the Fund each day, depending on the daily fluctuation in the value of the contract. For certain futures, including foreign denominated futures, variation margin is not settled daily, but is recorded as a net variation margin payable or receivable. The daily changes in contract value are recorded as unrealized appreciation or depreciation in the Statement of Operations and the Fund recognizes a realized gain or loss when the contract is closed.
Futures contracts involve, to varying degrees, risk of loss in excess of the amounts reflected in the financial statements. In addition, there is the risk that the Fund may not be able to enter into a closing transaction because of an illiquid secondary market.
(c) Swap agreements.The Fund invests in swaps for the purpose of managing its exposure to interest rate, credit or market risk, or for other purposes. The use of swaps involves risks that are different from those associated with other portfolio transactions.
Western Asset SMASh Series M Fund 2024 Semi-Annual Report

25

Notes to Financial Statements (unaudited) (cont’d)
Swap agreements are privately negotiated in the over-the-counter market and may be entered into as a bilateral contract (“OTC Swaps”) or centrally cleared (“Centrally Cleared Swaps”). Unlike Centrally Cleared Swaps, the Fund has credit exposure to the counterparties of OTC Swaps.
In a Centrally Cleared Swap, immediately following execution of the swap, the swap agreement is submitted to a clearinghouse or central counterparty (the “CCP”) and the CCP becomes the ultimate counterparty of the swap agreement. The Fund is required to interface with the CCP through a broker, acting in an agency capacity. All payments are settled with the CCP through the broker. Upon entering into a Centrally Cleared Swap, the Fund is required to deposit initial margin with the broker in the form of cash or securities.
Swap contracts are marked-to-market daily and changes in value are recorded as unrealized appreciation (depreciation). The daily change in valuation of Centrally Cleared Swaps, if any, is recorded as a net receivable or payable for variation margin on the Statement of Assets and Liabilities. Gains or losses are realized upon termination of the swap agreement. Collateral, in the form of restricted cash or securities, may be required to be held in segregated accounts with the Fund’s custodian in compliance with the terms of the swap contracts. Securities posted as collateral for swap contracts are identified in the Schedule of Investments and restricted cash, if any, is identified on the Statement of Assets and Liabilities. Risks may exceed amounts recorded in the Statement of Assets and Liabilities. These risks include changes in the returns of the underlying instruments, failure of the counterparties to perform under the contracts’ terms, and the possible lack of liquidity with respect to the swap agreements.
OTC Swap payments received or made at the beginning of the measurement period are reflected as a premium or deposit, respectively, on the Statement of Assets and Liabilities. These upfront payments are amortized over the life of the swap and are recognized as realized gain or loss in the Statement of Operations. Net periodic payments received or paid by the Fund are recognized as a realized gain or loss in the Statement of Operations.
The Fund’s maximum exposure in the event of a defined credit event on a credit default swap to sell protection is the notional amount. As of August 31, 2024, the total notional value of all credit default swaps to sell protection was $130,599,000. This amount would be offset by the value of the swap’s reference entity, upfront premiums received on the swap and any amounts received from the settlement of a credit default swap where the Fund bought protection for the same referenced security/entity.
For average notional amounts of swaps held during the sixmonths ended August 31, 2024, see Note 4.
Credit default swaps
The Fund enters into credit default swap (“CDS”) contracts for investment purposes, to manage its credit risk or to add leverage. CDS agreements involve one party making a

26
Western Asset SMASh Series M Fund 2024 Semi-Annual Report

stream of payments to another party in exchange for the right to receive a specified return in the event of a default by a third party, typically corporate or sovereign issuers, on a specified obligation, or in the event of a write-down, principal shortfall, interest shortfall or default of all or part of the referenced entities comprising a credit index. The Fund may use a CDS to provide protection against defaults of the issuers (i.e., to reduce risk where the Fund has exposure to an issuer) or to take an active long or short position with respect to the likelihood of a particular issuer’s default. As a seller of protection, the Fund generally receives an upfront payment or a stream of payments throughout the term of the swap provided that there is no credit event. If the Fund is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the maximum potential amount of future payments (undiscounted) that the Fund could be required to make under a CDS agreement would be an amount equal to the notional amount of the agreement. These amounts of potential payments will be partially offset by any recovery of values from the respective referenced obligations. As a seller of protection, the Fund effectively adds leverage to its portfolio because, in addition to its total net assets, the Fund is subject to investment exposure on the notional amount of the swap. As a buyer of protection, the Fund generally receives an amount up to the notional value of the swap if a credit event occurs.
Implied spreads are the theoretical prices a lender receives for credit default protection. When spreads rise, market perceived credit risk rises and when spreads fall, market perceived credit risk falls. The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to enter into the agreement. Wider credit spreads and decreasing market values, when compared to the notional amount of the swap, represent a deterioration of the referenced entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement. Credit spreads utilized in determining the period end market value of CDS agreements on corporate or sovereign issues are disclosed in the Schedule of Investments and serve as an indicator of the current status of the payment/performance risk and represent the likelihood or risk of default for credit derivatives. For CDS agreements on asset-backed securities and credit indices, the quoted market prices and resulting values, particularly in relation to the notional amount of the contract as well as the annual payment rate, serve as an indication of the current status of the payment/performance risk.
The Fund’s maximum risk of loss from counterparty risk, as the protection buyer, is the fair value of the contract (this risk is mitigated by the posting of collateral by the counterparty to the Fund to cover the Fund’s exposure to the counterparty). As the protection seller, the Fund’s maximum risk is the notional amount of the contract. CDS are considered to have credit risk-related contingent features since they require payment by the protection seller to the protection buyer upon the occurrence of a defined credit event.

Notes to Financial Statements (unaudited) (cont’d)
Entering into a CDS agreement involves, to varying degrees, elements of credit, market and documentation risk in excess of the related amounts recognized on the Statement of Assets and Liabilities. Such risks involve the possibility that there will be no liquid market for these agreements, that the counterparty to the agreement may default on its obligation to perform or disagree as to the meaning of the contractual terms in the agreement, and that there will be unfavorable changes in net interest rates.
(d) Stripped securities.The Fund may invest in ‘‘Stripped Securities,’’ a term used collectively for components, or strips, of fixed income securities. Stripped Securities can be principal only securities (“PO”), which are debt obligations that have been stripped of unmatured interest coupons, or interest only securities (“IO”), which are unmatured interest coupons that have been stripped from debt obligations. The market value of Stripped Securities will fluctuate in response to changes in economic conditions, rates of pre-payment, interest rates and the market’s perception of the securities. However, fluctuations in response to interest rates may be greater in Stripped Securities than for debt obligations of comparable maturities that pay interest currently. The amount of fluctuation may increase with a longer period of maturity.
The yield to maturity on IO’s is sensitive to the rate of principal repayments (including prepayments) on the related underlying debt obligation and principal payments may have a material effect on yield to maturity. If the underlying debt obligation experiences greater than anticipated prepayments of principal, the Fund may not fully recoup its initial investment in IO’s.
(e) Repurchase agreements.The Fund 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 Fund acquires a debt security subject to an obligation of the seller to repurchase, and of the Fund to resell, the security at an agreed-upon price and time, thereby determining the yield during the Fund’s holding period. When entering into repurchase agreements, it is the Fund’s policy that its custodian or a third party custodian, acting on the Fund’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 Fund 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 Fund 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 Fund may be delayed or limited.

Western Asset SMASh Series M Fund 2024 Semi-Annual Report

(f) Securities traded on a to-be-announced basis.The Fund may trade securities on a to-be-announced (“TBA”) basis. In a TBA transaction, the Fund commits to purchasing or selling securities which have not yet been issued by the issuer and for which specific information, such as the face amount, maturity date and underlying pool of investments in U.S. government agency mortgage pass-through securities, is not announced. Securities purchased on a TBA basis are not settled until they are delivered to the Fund. Beginning on the date the Fund enters into a TBA transaction, cash, U.S. government securities or other liquid high-grade debt obligations are segregated in an amount equal in value to the purchase price of the TBA security. These securities are subject to market fluctuations and their current value is determined in the same manner as for other securities.
At August 31, 2024, the Fund held non-cash collateral for TBA securities from Bank of America N.A., Goldman Sachs Group Inc. and Morgan Stanley & Co. Inc. in the amounts of $1,033,813, $101,052 and $265,311 respectively.
(g) Mortgage dollar rolls.The Fund may enter into mortgage dollar rolls in which the Fund sells mortgage-backed securities for delivery in the current month, realizing a gain or loss, and simultaneously entering into contracts to repurchase substantially similar (same type, coupon and maturity) securities to settle on a specified future date.
The Fund executes its mortgage dollar rolls entirely in the TBA market, whereby the Fund makes a forward commitment to purchase a security and, instead of accepting delivery, the position is offset by a sale of the security with a simultaneous agreement to repurchase at a future date. The Fund accounts for mortgage dollar rolls as purchases and sales.
The risk of entering into mortgage dollar rolls is that the market value of the securities the Fund is obligated to repurchase under the agreement may decline below the repurchase price. In the event the buyer of securities under a mortgage dollar roll files for bankruptcy or becomes insolvent, the Fund’s use of the proceeds of the mortgage dollar roll may be restricted pending a determination by the counterparty, or its trustee or receiver, whether to enforce the Fund’s obligation to repurchase the securities.
(h) Credit and market risk.The Fund invests in high-yield and emerging market instruments that are subject to certain credit and market risks. The yields of high-yield and emerging market debt obligations reflect, among other things, perceived credit and market risks. The Fund’s investments in securities rated below investment grade typically involve risks not associated with higher rated securities including, among others, greater risk related to timely and ultimate payment of interest and principal, greater market price volatility and less liquid secondary market trading. The consequences of political, social, economic or diplomatic changes may have disruptive effects on the market prices of investments held by the Fund. The Fund’s investments in non-U.S. dollar denominated securities may also result in foreign currency losses caused by devaluations and exchange rate fluctuations.

Notes to Financial Statements (unaudited) (cont’d)
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.
(i) Foreign investment risks.The Fund’s investments in foreign securities may involve risks not present in domestic investments. Since securities may be denominated in foreign currencies, may require settlement in foreign currencies or may pay interest or dividends in foreign currencies, changes in the relationship of these foreign currencies to the U.S. dollar can significantly affect the value of the investments and earnings of the Fund. Foreign investments may also subject the Fund to foreign government exchange restrictions, expropriation, taxation or other political, social or economic developments, all of which affect the market and/or credit risk of the investments.
(j) Counterparty risk and credit-risk-related contingent features of derivative instruments.The Fund may invest in certain securities or engage in other transactions where the Fund is exposed to counterparty credit risk in addition to broader market risks. The Fund may invest in securities of issuers, which may also be considered counterparties as trading partners in other transactions. This may increase the risk of loss in the event of default or bankruptcy by the counterparty or if the counterparty otherwise fails to meet its contractual obligations. The Fund’s subadviser attempts to mitigate counterparty risk by (i) periodically assessing the creditworthiness of its trading partners, (ii) monitoring and/or limiting the amount of its net exposure to each individual counterparty based on its assessment and (iii) requiring collateral from the counterparty for certain transactions. Market events and changes in overall economic conditions may impact the assessment of such counterparty risk by the subadviser. In addition, declines in the values of underlying collateral received may expose the Fund to increased risk of loss.
With exchange traded and centrally cleared derivatives, there is less counterparty risk to the Fund since the exchange or clearinghouse, as counterparty to such instruments, guarantees against a possible default. The clearinghouse stands between the buyer and the seller of the contract; therefore, the credit risk is limited to failure of the clearinghouse. While offset rights may exist under applicable law, the Fund does not have a contractual right of offset against a clearing broker or clearinghouse in the event of a default of the clearing broker or clearinghouse.
The Fund has entered into master agreements, such as an International Swaps and Derivatives Association, Inc. Master Agreement (“ISDA Master Agreement”) or similar agreement, with certain of its derivative counterparties that govern over-the-counter (OTC) derivatives and provide for general obligations, representations, agreements,

30
Western Asset SMASh Series M Fund 2024 Semi-Annual Report

collateral posting terms, netting provisions in the event of default or termination and credit related contingent features. The credit related contingent features include, but are not limited to, a percentage decrease in the Fund’s net assets or net asset value per share over a specified period of time. If these credit related contingent features were triggered, the derivatives counterparty could terminate the positions and demand payment or require additional collateral.
Under an ISDA Master Agreement, the Fund may, under certain circumstances, offset with the counterparty certain derivative financial instruments’ payables and/or receivables with collateral held and/or posted and create one single net payment. However, absent an event of default by the counterparty or a termination of the agreement, the terms of the ISDA Master Agreements do not result in an offset of reported amounts of financial assets and financial liabilities in the Statement of Assets and Liabilities across transactions between the Fund and the applicable counterparty. The enforceability of the right to offset may vary by jurisdiction.
Collateral requirements differ by type of derivative. Collateral or margin requirements are set by the broker or exchange clearinghouse for exchange traded derivatives while collateral terms are contract specific for OTC traded derivatives. Cash collateral that has been pledged to cover obligations of the Fund under derivative contracts, if any, will be reported separately in the Statement of Assets and Liabilities. Securities pledged as collateral, if any, for the same purpose are noted in the Schedule of Investments.
As of August 31, 2024, the Fund did not have any open OTC derivative transactions with credit related contingent features in a net liability position.
(k) Security transactions and investment income.Security transactions are accounted for on a trade date basis. Interest income (including interest income from payment-in-kind securities) is recorded on the accrual basis. Amortization of premiums and accretion of discounts on debt securities are recorded to interest income over the lives of the respective securities, except for premiums on certain callable debt securities, which are amortized to the earliest call date. Paydown gains and losses on mortgage- and asset-backed securities are recorded as adjustments to interest income. Dividend income is recorded on the ex-dividend date for dividends received in cash and/or securities. The cost of investments sold is determined by use of the specific identification method. To the extent any issuer defaults or a credit event occurs that impacts the issuer, the Fund may halt any additional interest income accruals and consider the realizability of interest accrued up to the date of default or credit event.
(l) Distributions to shareholders.Distributions from net investment income of the Fund, if any, are declared and paid on a monthly basis. Distributions of net realized gains, if any, are declared at least annually. Distributions to shareholders of the Fund are recorded on the
Western Asset SMASh Series M Fund 2024 Semi-Annual Report

31

Notes to Financial Statements (unaudited) (cont’d)
ex-dividend date and are determined in accordance with income tax regulations, which may differ from GAAP.
(m) Compensating balance arrangements.The Fund has an arrangement with its custodian bank whereby a portion of the custodian’s fees is paid indirectly by credits earned on the Fund’s cash on deposit with the bank.
(n) 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 February 29, 2024, 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 tax years for which the applicable statutes of limitations have not expired are subject to examination by the Internal Revenue Service and state departments of revenue.
(o) Reclassification.GAAP requires that certain components of net assets be reclassifiedto 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
FTFA is the Fund’s investment manager. Western Asset Management Company, LLC (“Western Asset”) and Western Asset Management Company Limited (“Western Asset London”) are the Fund’s subadvisers. FTFA, Western Asset and Western Asset London are indirect, wholly-owned subsidiaries of Franklin Resources, Inc. (“Franklin Resources”).
FTFA and the subadvisers do not charge investment management fees to the Fund. However, the Fund is an integral part of the separately managed account program, and FTFA and the subadvisers will be compensated directly or indirectly by separately managed account program sponsors. FTFA provides administrative and certain oversight services to the Fund. FTFA delegates to the subadvisers the day-to-day portfolio management of the Fund.
FTFA has entered into an expense reimbursement arrangement with the Fund, pursuant to which FTFA has agreed to reimburse 100% of the Fund’s ordinary operating expenses. The expense reimbursement arrangement does not cover interest, brokerage, taxes and extraordinary expenses. This expense reimbursement arrangement cannot be terminated prior to December 31, 2025 without the Board of Trustees’ consent.

Board Approval of Management and
Subadvisory Agreements (unaudited)
The Executive and Contracts Committee of the Board of Trustees (the “Executive and Contracts Committee”) considered the Management Agreement between the Trust and Franklin Templeton Fund Adviser, LLC (“FTFA”) (formerly known as Legg Mason Partners Fund Advisor, LLC) with respect to the Fund and the following subadvisory agreements with respect to the Fund (collectively, the “Agreements”) (i) a subadvisory agreement between FTFA and Western Asset Management Company, LLC (“Western Asset”) with respect to the Fund, and (ii) a subadvisory agreement between FTFA and Western Asset Management Company Limited (“WAML” or the “Non-U.S. Subadviser,” and together with Western Asset, the “Subadvisers,” and together with FTFA, the “Advisers”) with respect to the Fund at a meeting held on April 30, 2024. At an in-person meeting held on May 16, 2024, the Executive and Contracts Committee reported to the full Board of Trustees their considerations and recommendation with respect to the Agreements, and the Board of Trustees, including a majority of the Independent Trustees, considered and approved renewal of the Agreements.
The Trustees noted that although Western Asset’s business is operated through separate legal entities, such as the Non-U.S. Subadviser, senior investment personnel at Western Asset have supervisory oversight responsibility over the investment decisions made by the Non-U.S. Subadviser. Therefore, in connection with their deliberations noted below, the Trustees primarily focused on the information provided by Western Asset when considering the approval of the Agreement between FTFA and the Non-U.S. Subadviser.
In arriving at their decision to approve the renewal of the Agreements, the Trustees met with representatives of the Advisers, including relevant investment advisory personnel; considered a variety of information prepared by the Advisers, materials provided by Broadridge and advice and materials provided by counsel to the Independent Trustees; reviewed performance and expense information for peer groups of comparable funds selected by Broadridge (the “Performance Universe”) and certain other comparable products available from Western Asset or affiliates of Western Asset, including separate accounts managed by Western Asset; and requested and reviewed additional information as necessary. These reviews were in addition to information obtained by the Trustees at their regular quarterly meetings (and various committee meetings) with respect to the Fund’s performance and other relevant matters and related discussions with the Advisers’ personnel. The information received and considered by the Board both in conjunction with the May meeting and at prior meetings was both written and oral. With respect to the Broadridge materials, the Board was provided with a description of the methodology used to determine the similarity of the Fund with the funds included in the Performance Universe. It was noted that while the Board found the Broadridge data generally useful they recognized its limitations, including that the data may vary depending on the end date selected and that the results of the performance comparisons may vary depending on the selection of the peer group and its composition over time. In considering the Fund’s
Western Asset SMASh Series M Fund

37

Board Approval of Management and
Subadvisory Agreements (unaudited) (cont’d)
performance, the Board took into account that the Fund is offered only to participants in separately managed account programs who pay costs and expenses, including fees for advice and portfolio execution, at the level of such programs rather than at the Fund level.
As part of their review, the Trustees examined FTFA’s ability to provide high quality oversight and administrative and shareholder support services to the Fund and the Subadvisers’ ability to provide high quality investment management services to the Fund. The Trustees considered the experience of FTFA’s personnel in providing the types of services that FTFA is responsible for providing to the Fund; the ability of FTFA to attract and retain capable personnel; and the capability and integrity of FTFA’s senior management and staff. The Trustees also considered the investment philosophy and research and decision-making processes of the Subadvisers; the experience of their key advisory personnel responsible for management of the Fund; the ability of the Subadvisers to attract and retain capable research and advisory personnel; the risks to the Advisers associated with sponsoring the Fund (such as entrepreneurial, operational, reputational, litigation and regulatory risk), as well as FTFA’s and each Subadviser’s risk management processes; the capability and integrity of the Advisers’ senior management and staff; and the level of skill required to manage the Fund. In addition, the Trustees reviewed the quality of the Advisers’ services with respect to regulatory compliance and compliance with the investment policies of the Fund, and conditions that might affect the Advisers’ ability to provide high quality services to the Fund in the future, including their business reputations, financial conditions and operational stabilities. Based on the foregoing, the Trustees concluded that the Subadvisers’ investment process, research capabilities and philosophy were well suited to the Fund given its investment objectives and policies, and that the Advisers would be able to meet any reasonably foreseeable obligations under the Agreements.
The Board reviewed the qualifications, backgrounds and responsibilities of FTFA’s and Western Asset’s senior personnel and the team of investment professionals primarily responsible for the day-to-day portfolio management of the Fund. The Board also considered, based on its knowledge of FTFA and its affiliates, the financial resources of Franklin Resources, Inc., the parent organization of the Advisers. The Board recognized the importance of having a fund manager with significant resources.
In reviewing the quality of the services provided to the Fund, the Trustees also reviewed comparisons of the performance of the Fund to the performance of certain comparable funds and to its investment benchmark over the 1-, 3-, 5- and 10-year periods ended December 31, 2023. The information comparing the Fund’s performance to that of its Performance Universe, consisting of all funds (including the Fund) classified as retail and institutional global income funds by Broadridge, showed, among other data, that the Fund’s performance for the 10-year period ended December 31, 2023 was above the median and that the Fund’s performance for the 1-, 3- and 5-year periods ended December 31, 2023 was

38
Western Asset SMASh Series M Fund

below the median. The Board noted that the Fund’s performance exceeded that of its benchmark index for the 10-year period ended December 31, 2023, was approximately equal to the performance of its benchmark index for the 1-year period ended December 31, 2023 and trailed the performance of its benchmark index for the 3- and 5-year periods ended December 31, 2023. The Board considered the factors involved in the Fund’s performance relative to the performance of its investment benchmark and Performance Universe.
The Board noted that the Fund does not pay a management fee. The Board also noted that the Fund is an integral part of the separately managed account program, and the Advisers are compensated directly or indirectly by separately managed account program sponsors. The Board recognized that FTFA had agreed to pay all operating expenses of the Fund, except interest, brokerage, taxes, and extraordinary expenses. The Board considered that this arrangement is expected to continue through December 2025.
The Trustees further evaluated the benefits of the advisory relationship to the Advisers, including, among others, the profitability of the relationship to the Advisers; the direct and indirect benefits that the Advisers may receive from their relationships with the Fund, including the “fallout benefits,” such as reputational value derived from serving as investment adviser to the Fund; and the affiliation between the Advisers and certain other service providers for the Fund. In that connection, the Board considered that the ancillary benefits that the Advisers receive were reasonable. The Trustees noted that Western Asset does not have soft dollar arrangements.
Finally, the Trustees considered, in light of the profitability information provided by the Advisers, the extent to which economies of scale would be realized by the Advisers as the assets of the Fund grow. The Board discussed whether FTFA realizes economies of scale as the Fund’s assets grow. Among other things, the Board considered that the Fund pays no management fees to FTFA. The Board also noted that FTFA has agreed to pay all operating expenses of the Fund, except interest, brokerage, taxes, and extraordinary expenses.
In their deliberations with respect to these matters, the Independent Trustees were advised by their independent counsel, who is independent, within the meaning of the Securities and Exchange Commission rules regarding the independence of counsel, of the Advisers. The Independent Trustees weighed the foregoing matters in light of the advice given to them by their independent counsel as to the law applicable to the review of investment advisory contracts. In arriving at a decision, the Trustees, including the Independent Trustees, did not identify any single matter as all-important or controlling, and each Trustee may have attributed different weight to the various factors in evaluating the Agreements. The foregoing summary does not detail all the matters considered. The Trustees judged the terms and conditions of the Agreements in light of all of the surrounding circumstances.

Board Approval of Management and
Subadvisory Agreements (unaudited) (cont’d)
Based upon their review, the Trustees, including all of the Independent Trustees, determined, in the exercise of their business judgment, that they were satisfied with the quality of investment advisory services being provided by the Advisers and that approval of the Agreements was in the best interest of the Fund and its shareholders.
