ITEM 3. AUDIT COMMITTEE FINANCIAL EXPERT.

The Board of Trustees of the Registrant has determined that Robert Abeles, Jr., possesses the technical attributes identified in Item 3 to Form N-CSR to qualify as an "audit committee financial expert," and has designated Mr. Abeles, Jr. as the Audit Committee's financial expert. Mr. Abeles, Jr. is an "independent" Trustee pursuant to paragraph (a)(2) of Item 3 to Form N-CSR.

Under applicable securities laws, a person determined to be an audit committee financial expert will not be deemed an "expert" for any purpose, including without limitation for the purposes of Section 11 of the Securities Act of 1933, as a result of being designated or identified as an audit committee financial expert. The designation or identification of a person as an audit committee financial expert does not impose on such person any duties, obligations, or liabilities greater than the duties, obligations, and liabilities imposed on such person as a member of the audit committee and board of directors in the absence of such designation or identification. The designation or identification of a person as an audit committee financial expert does not affect the duties, obligations, or liability of any other member of the audit committee or board of directors.

ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES.

a) Audit Fees. The aggregate fees billed in the last two fiscal years ending February 28, 2025 and February 28, 2026 (the "Reporting Periods") for professional services rendered by the Registrant's principal accountant (the "Auditor") for the audit of the Registrant's annual financial statements, or services that are normally provided by the Auditor in connection with the statutory and regulatory filings or engagements for the Reporting Periods, were $160,218 in February 28, 2025 and $161,820 in February 28, 2026.

b) Audit-Related Fees. The aggregate fees billed in the Reporting Periods for assurance and related services by the Auditor that are reasonably related to the performance of the Registrant's financial statements were $0 in February 28, 2025 and $0 in February 28, 2026.

(c) Tax Fees. The aggregate fees billed in the Reporting Periods for professional services rendered by the Auditor for tax compliance, tax advice and tax planning ("Tax Services") were $40,000 in February 28, 2025 and $40,000 in February 28, 2026. These services consisted of (i) review or preparation of U.S. federal, state, local and excise tax returns; (ii) U.S. federal, state and local tax planning, advice and assistance regarding statutory, regulatory or administrative developments, and (iii) tax advice regarding tax qualification matters and/or treatment of various financial instruments held or proposed to be acquired or held.

There were no fees billed for tax services by the Auditors to the Registrant's investment manager and any entity controlling, controlled by, or under common control with the investment manager that provides ongoing services to the Registrant ("Service Affiliates") during the Reporting Periods that required pre-approval by the Audit Committee.

d) All Other Fees. The aggregate fees billed in the Reporting Periods for products and services provided by the Auditor to the Registrant, other than the services reported in paragraphs (a) through (c) of this item, were $0 in February 28, 2025 and $0 in February 28, 2026.

There were no other non-audit services rendered by the Auditor to the Service Affiliates requiring pre-approval by the Audit Committee in the Reporting Periods.

(e) Audit Committee's pre-approval policies and procedures described in paragraph (c) (7) of Rule 2-01 of Regulation S-X.

(1) The Charter for the Audit Committee (the "Committee") of the Board of each registered investment company (the "Fund") advised by the Registrant's investment manager or one of their affiliates (each, an "Adviser") requires that the Committee shall approve (a) all audit and permissible non-audit services to be provided to the Fund and (b) all permissible non-audit services to be provided by the Fund's independent auditors to the Adviser and any service providers controlling, controlled by or under common control with the Adviser that provide ongoing services to the Fund ("Covered Service Providers") if the engagement relates directly to the operations and financial reporting of the Fund. The Committee may implement policies and procedures by which such services are approved other than by the full Committee.

The Committee shall not approve non-audit services that the Committee believes may impair the independence of the auditors. As of the date of the approval of this Audit Committee Charter, permissible non-audit services include any professional services (including tax services), that are not prohibited services as described below, provided to the Fund by the independent auditors, other than those provided to the Fund in connection with an audit or a review of the financial statements of the Fund. Permissible non-audit services may not include: (i) bookkeeping or other services related to the accounting records or financial statements of the Fund; (ii) financial information systems design and implementation; (iii) appraisal or valuation services, fairness opinions or contribution-in-kind reports; (iv) actuarial services; (v) internal audit outsourcing services; (vi) management functions or human resources; (vii) broker or dealer, investment adviser or investment banking services; (viii) legal services and expert services unrelated to the audit; and (ix) any other service the Public Company Accounting Oversight Board determines, by regulation, is impermissible.

Pre-approval by the Committee of any permissible non-audit services is not required so long as: (i) the aggregate amount of all such permissible non-audit services provided to the Fund, the Adviser and the Covered Service Providers constitutes not more than 5% of the total amount of revenues paid to the independent auditors during the fiscal year in which the permissible non-audit services are provided to (a) the Fund, (b) the Adviser and (c) any entity controlling, controlled by or under common control with the Adviser that provides ongoing services to the Fund during the fiscal year in which the services are provided that would have to be approved by the Committee; (ii) the permissible non-audit services were not recognized by the Fund at the time of the engagement to be non-audit services; and (iii) such services are promptly brought to the attention of the Committee and approved by the Committee (or its delegate(s)) prior to the completion of the audit.

(2) None of the services described in paragraphs (b) through (d) of this Item were performed in reliance on paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

(f) Not applicable.

(g) Non-audit fees billed by the Auditor for services rendered to the Registrant and the Service Affiliates during the reporting period were $334,889 in February 28, 2025 and $344,935 in February 28, 2026.

(h) Yes. The Registrant's Audit Committee has considered whether the provision of non-audit services that were rendered to Service Affiliates, which were not pre-approved (not requiring pre-approval), is compatible with maintaining the Auditor's independence. All services provided by the Auditor to the Registrant or to the Service Affiliates, which were required to be pre-approved, were pre-approved as required.

(i) Not applicable.

(j) Not applicable.

Western Asset SMASh Series TF Fund 2026 Annual Report
Notes to Financial Statements
1. Organization and significant accounting policies
Western Asset SMASh Series TF 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 subadviser 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-endfunds 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. 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 security has been significantly affected by events after the close of the exchange

Notes to Financial Statements(cont'd)
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 (the "Board").
Pursuant to policies adopted by the Board, 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. 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, 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 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 generated by market transactions involving identical or comparable securities. The income approach uses valuation techniques to discount estimated future cash flows to present value.
24
Western Asset SMASh Series TF Fund 2026 Annual Report
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 carried at fair value:

See Schedule of Investments for additional detailed categorizations.
(b) Tender option bonds.The Fund may enter into tender option bond ("TOB") transactions and may invest in inverse floating rate instruments ("Inverse Floaters") issued in TOB transactions. The Fund may participate either in structuring an Inverse Floater or purchasing an Inverse Floater in the secondary market. When structuring an Inverse Floater, the Fund deposits securities (typically municipal bonds or other municipal securities) (the "Underlying Bonds") into a special purpose entity, referred to as a TOB trust. The TOB trust generally issues floating rate notes ("Floaters") to third parties and residual interest, Inverse Floaters, to the Fund. The Floaters issued by the TOB trust have interest rates which reset weekly and provide the holders of the Floaters the option to tender their notes back to the TOB trust for redemption at par at each reset date. The net proceeds of the sale of the Floaters, after expenses, are received by the Fund and may be invested in additional securities. The Inverse Floaters are inverse floating rate debt instruments, as the return on those bonds is inversely related to changes in a specified interest rate. Distributions on any Inverse Floaters paid to the Fund will be reduced or, in the extreme, eliminated as short-term interest rates rise and will increase when such interest rates fall. Floaters issued by a TOB
Western Asset SMASh Series TF Fund 2026 Annual Report
25
Notes to Financial Statements(cont'd)
trust may be senior to the Inverse Floaters held by the Fund. The value and market for Inverse Floaters can be volatile, and Inverse Floaters can have limited liquidity.
An investment in an Inverse Floater structured by the Fund is accounted for as a secured borrowing. The Underlying Bonds deposited into the TOB trust are included in the Fund's Schedule of Investments and a liability for Floaters (TOB floating rate notes) issued by the TOB trust is recognized in the Fund's Statement of Assets and Liabilities. The carrying amount of the TOB trust's floating rate note obligations as reported on the Statement of Assets and Liabilities approximates its fair value. Interest income, including amortization, on the Underlying Bonds is recognized in the Fund's Statements of Operations. Interest paid to holders of the Floaters, as well as other expenses related to administration, liquidity, remarketing and trustee services of the TOB trust, are recognized in Interest expense in the Fund's Statement of Operations. For the year ended February 28, 2026, the average daily amount of floating rate notes outstanding was $1,165,000 and weighted average interest rate was 3.12%.
(c) 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.
(d) Securities traded on a when-issued and delayed delivery basis.The Fund may trade securities on a when-issued or delayed delivery basis. In when-issued and delayed delivery transactions, the securities are purchased or sold by the Fund with payment and delivery taking place in the future in order to secure what is considered to be an advantageous price and yield to the Fund at the time of entering into the transaction.
Purchasing such securities involves risk of loss if the value of the securities declines prior to settlement. These securities are subject to market fluctuations and their current value is determined in the same manner as for other securities.
26
Western Asset SMASh Series TF Fund 2026 Annual Report
(e) 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, 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
Western Asset SMASh Series TF Fund 2026 Annual Report
27
Notes to Financial Statements(cont'd)
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 February 28, 2026, the Fund did not have any open OTC derivative transactions with credit related contingent features in a net liability position.
(f) 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. 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.
(g) Distributions to shareholders.Distributions from net investment income of the Fund, if any, are declared and paid on a monthly basis. The Fund intends to satisfy conditions that will enable interest from municipal securities, which is exempt from federal and certain state income taxes, to retain such tax-exempt status when distributed to the shareholders of the Fund. Distributions of net realized gains, if any, are taxable and 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.
(h) Compensating balance arrangements.The Fund had an arrangement with its custodian bank whereby a portion of the custodian's fees was paid indirectly by credits earned on the Fund's cash on deposit with the bank. Effective April 1, 2025, any cash on deposit with the bank will earn interest and be recognized as interest income on the Statement of Operations.
(i) 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 28, 2026, 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.

Western Asset SMASh Series TF Fund 2026 Annual Report
(j) 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. During the current year, the Fund had no reclassifications.
2. Investment management agreement and other transactions with affiliates

The Global Credit Facility provides a source of funds to the Borrowers for temporary and emergency purposes, including the ability to meet future unanticipated or unusually large redemption requests. Unless renewed, the Global Credit Facility will terminate on January 29, 2027.
Under the terms of the Global Credit Facility, the Fund shall, in addition to interest charged on any borrowings made by the Fund and other costs incurred by the Fund, pay its share of fees and expenses incurred in connection with the implementation and maintenance of the Global Credit Facility, based upon its relative share of the aggregate net assets of all the Borrowers, including an annual commitment fee of 0.15% based upon the unused portion of the Global Credit Facility. These fees are reflected in the Statement of Operations. The Fund did not utilize the Global Credit Facility during the year ended February 28, 2026.
