Western Asset SMASh Series TF Fund

Fund overview

Q. What is the Fund’s investment strategy?

A. The Fund seeks to maximize current interest income that is excluded from gross income for regular federal income tax purposes. Under normal circumstances, the Fund invests at least 80% of its assets in municipal securities and other investments with similar economic characteristics, the interest on which is exempt from regular federal income tax but which may be subject to the federal alternative minimum tax. Municipal securities include debt obligations issued by any of the 50 states and certain other municipal issuers and their political subdivisions, agencies and public authorities, certain other governmental issuers (such as Puerto Rico, the U.S. Virgin Islands and Guam) and other qualifying issuers. These securities include participation or other interests in municipal securities issued or backed by banks, insurance companies and other financial institutions.

Although the Fund may invest in securities of any maturity, it normally invests in intermediate-term and long-term municipal securities that have remaining maturities from one to more than thirty years at the time of purchase. The Fund typically focuses on investment grade bonds (that is, securities rated in the Baa/BBB categories or above or, if unrated, that we determined to be of comparable credit quality) but may from time to time invest, to no specified limit, in below investment grade bonds (commonly known as “high yield” or “junk” bonds).

Some municipal securities, such as general obligation issues, are backed by the issuer’s taxing authority, while other municipal securities, such as revenue issues, are backed only by revenues from certain facilities or other sources and not by the issuer itself.

Instead of, and/or in addition to, investing directly in particular securities, the Fund may use instruments such as derivatives, including options, futures contracts and inverse floating rate instruments issued in tender option bond transactions, and other synthetic instruments that are intended to provide economic exposure to the securities or the issuer or to be used as a hedging technique. The Fund may use one or more types of these instruments without limit, except that these instruments are taken into account when determining compliance with the Fund’s 80% investment policy. The Fund may also engage in a variety of transactions using derivatives in order to change the investment characteristics of its portfolio (such as shortening or lengthening duration) and for other purposes. The Fund may leverage its assets by investing proceeds received through tender option bond transactions, which is considered a form of borrowing.

The fund is classified as “non-diversified,” which means it may invest a larger percentage of its assets in a smaller number of issuers than a diversified fund.

At Western Asset Management Company, LLC (“Western Asset”), the Fund’s subadviser, we utilize a fixed income team approach, with decisions derived from interaction among various investment management sector specialists. The sector teams are comprised of Western Asset’s senior portfolio management personnel, research analysts and an in-house

economist. Under this team approach, management of client fixed income portfolios will reflect a consensus of interdisciplinary views within the Western Asset organization.

Q. What were the overall market conditions during the Fund’s reporting period?

A. The fixed income market experienced periods of elevated volatility and posted a positive return during the twelve-month reporting period ended February 29, 2024. The market was impacted by several factors, including initial fears of an economic recession, persistent inflation, and shifting expectations for Federal Reserve Board (the “Fed”) monetary policy. There was also brief turmoil in the regional banking industry and a host of geopolitical issues that impacted investor sentiment. The market ended 2023 on a positive note, as the Fed indicated it would likely pivot from raising rates to cutting rates in 2024. However, the Fed appears to be taking a measured approach, which has pushed back expectations in terms of the timing for rate cuts in 2024. Meanwhile, there are signs that the central bank may orchestrate a “soft landing” for the economy.

Short-term U.S. Treasury yields declined as inflation moderated and the Fed indicated the likely end of its rate hike cycle. The yield for the two-year Treasury note began the reporting period at 4.81% and ended the period at 4.64%. The low of 3.75% was on May 4, 2023, and the peak of 5.19% occurred on October 17 and 18, 2023. The yield for the ten-year Treasury note began the reporting period at 3.92% and ended the period at 4.25%. The low of 3.30% was on April 5 and 6, 2023, and the peak of 4.98% occurred on October 19, 2023.

The municipal bond market generated a positive return and outperformed its taxable bond counterpart during the twelve-month reporting period. Over that time, the Bloomberg Municipal Bond Indexⁱ and the Bloomberg U.S. Aggregate Indexⁱⁱ returned 5.42% and 3.33%, respectively. Both the taxable and tax-free markets were impacted by rising interest rates.

Q.How did we respond to these changing market conditions?

A. There were several adjustments to the Fund during the reporting period. We increased the Fund’s duration over the period. Elsewhere, we increased the Fund’s allocations to the industrial revenue sector, whereas we pared its health care exposure. From a quality perspective, we added to Fund’s allocation to AA-rated bonds, while paring exposure to BBB-rated bonds.

Performance review

For the twelve months ended February 29, 2024, Western Asset SMASh Series TF Fund returned 6.99%. The Fund’s unmanaged benchmark, the Bloomberg Municipal Bond Index, returned 5.42% for the same period.

The performance shown represents past performance. Past performance is no guarantee of future results and current performance may be higher or lower than the performance shown above. Principal value, investment returns and yields will fluctuate and investors’ shares, when redeemed, may be worth more or less than their original cost. To obtain performance data current to the most recent month-end, please call the Fund at 877-6LM-FUND/656-3863.

Fund returns assume the reinvestment of all distributions at net asset value and the deduction of all Fund expenses. Returns have not been adjusted to include the deduction of taxes that a shareholder would pay on Fund distributions. Performance figures for periods shorter than one year represent cumulative figures and are not annualized.

Investors should understand that the Fund is managed within the context of a separately managed account and not with the objective of matching or exceeding the Fund’s stated benchmark, which is used for Fund reporting purposes. As such, comparisons of the Fund’s performance to that of the indicated benchmark are not likely to be meaningful. Additionally, performance figures do not reflect the effect of fees and expenses associated with a separately managed account or the management fee or other operating expenses of the Fund. Such management fees are paid directly or indirectly by the separately managed account sponsor to the Fund’s manager or subadviser. All operating expenses of the Fund (other than interest, brokerage, taxes and extraordinary expenses) are reimbursed by the manager.

Total Annual Operating Expenses (unaudited)

As of the Fund’s current prospectus dated June 29, 2023, the gross total annual fund operating expense ratio for the Fund was 0.21%.

Actual expenses may be higher. For example, expenses may be higher than those shown if average net assets decrease. Net assets are more likely to decrease and Fund expense ratios are more likely to increase when markets are volatile.

The Fund’s manager has entered into an expense reimbursement arrangement with the Fund, pursuant to which the Fund’s manager 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. However, all Fund shareholders are participating in separately managed account programs and pay fees to program sponsors for the costs and expenses of the program, including fees for investment advice and portfolio execution, some of which are used to compensate the Fund’s manager or subadviser for managing the Fund and to reimburse the Fund for all operating expenses.

Q. What were the leading contributors to performance?

A. The largest contributor to the Fund’s relative performance during the reporting period was its security selection within a number of areas. Specifically, selection within the state general obligation, local general obligation and special tax obligation sectors was beneficial, as was selection within AA and BBB-rated bonds. Additionally, an overweight to BBB-rated securities and to the industrial revenue sector contributed to results.

Q. What were the leading detractors from performance?

A. Looking at sector positioning, security selection within the power sector detracted from returns, as did an overweight to the special tax obligation sector. An allocation to cash securities also detracted from results.

Thank you for your investment in the Western Asset SMASh Series TF Fund. As always, we appreciate that you have chosen us to manage your assets and we remain focused on achieving the Fund’s investment goals.

Sincerely,

Western Asset Management Company, LLC

RISKS: Investments in fixed income securities are subject to interest rate and credit risks. As interest rates rise, bond prices fall, thereby reducing the value of the Fund’s share price. High yield (“junk”) bonds possess greater price volatility, illiquidity and possibility of default. Municipal securities purchased by the Fund may be adversely affected by changes in the financial condition of municipal issuers and insurers, regulatory and political developments, uncertainties and public perceptions, and other factors. The Fund may use derivatives, such as options and futures, which can be illiquid, may disproportionately increase losses and have a potentially large impact on Fund performance. The use of leverage may increase volatility and possibility of loss. The Fund is classified as “non-diversified,” which means it may invest a larger percentage of its assets in a smaller number of issuers than a diversified fund. To the extent the Fund invests its assets in a small number of issuers, the Fund will be more susceptible to negative events affecting those issuers. The Fund may enter into tender option bond (“TOB”) transactions, which expose the Fund to leverage and credit risk, and generally involve greater risk than investments in fixed rate municipal bonds, including the risk of loss of principal. The interest payments that the Fund would typically receive on inverse floaters acquired in such transactions vary inversely with short-term interest rates and will be reduced (and potentially eliminated) when short-term interest rates increase. Inverse floaters will generally underperform the market for fixed rate municipal securities when interest rates rise. The value and market for inverse floaters can be volatile, and inverse floaters can have limited liquidity. Investments in inverse floaters issued in TOB transactions are derivative instruments and, therefore, are also subject to the risks generally applicable to investments in derivatives. The market values of securities or other assets will fluctuate, sometimes sharply and unpredictably, due to changes in general market conditions, overall economic trends or events, governmental actions or intervention, actions taken by the U.S. Federal Reserve or foreign central banks, market disruptions caused by trade disputes or other factors, political developments, armed conflicts, economic sanctions and countermeasures in response to sanctions, major cybersecurity events, investor sentiment, the global and domestic effects of a pandemic, and other factors that may or may not be related to the issuer of the security or other asset. Please see the Fund’s prospectus for a more complete discussion of these and other risks and the Fund’s investment strategies.

Fund expenses (unaudited)

Example

As a shareholder of the Fund, you may incur two types of costs: (1) transaction costs and (2) ongoing costs and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

This example is based on an investment of $1,000 invested on September 1, 2023 and held for the six months ended February 29, 2024.

Actual expenses

The table below titled “Based on actual total return” provides information about actual account values and actual expenses. You may use the information provided in this table, together with the amount you invested, to estimate the expenses that you paid over the period. To estimate the expenses you paid on your account, divide your ending account value by $1,000 (for example, an $8,600 ending account value divided by $1,000 = 8.6), then multiply the result by the number under the heading entitled “Expenses Paid During the Period”.

Hypothetical example for comparison purposes

The table below titled “Based on hypothetical total return” provides information about hypothetical account values and hypothetical expenses based on the actual expense ratio and an assumed rate of return of 5.00% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use the information provided in this table to compare the ongoing costs of investing in the Fund and other funds. To do so, compare the 5.00% hypothetical example relating to the Fund with the 5.00% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table below are meant to highlight your ongoing costs only and do not reflect any transactional costs. Therefore, the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher.

¹	For the six months ended February 29, 2024.

²	Total return is not annualized, as it may not be representative of the total return for the year. Past performance is no guarantee of future results. Performance figures do not reflect any fees stated below in Note 3. If such fees were included, the return shown would have been lower.

All figures do not reflect the effect of fees and expenses associated with a separately managed account, nor a management fee or other operating expenses of the Fund. Such management fees are paid directly or indirectly by the separately managed account sponsor to the Fund’s manager or subadviser. All operating expenses of the Fund were reimbursed by the manager, pursuant to an expense reimbursement arrangement between the Fund and the manager. The expense reimbursement arrangement does not cover interest, brokerage, taxes and extraordinary expenses.

⁴	Expenses (net of compensating balance arrangements, fee waivers and/or expense reimbursements) are equal to the Fund’s annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent fiscal half-year (182), then divided by 366.

⁵	Expense ratio reflects the impact of interest expense related to tender option bond transactions accounted for as secured borrowings for financial reporting purposes. Refer to Note 1 in the Notes to Financial Statements.

Western Asset SMASh Series TF Fund 2024 Annual Report

Notes to financial statements

1. Organization and significant accounting policies

Western Asset SMASh Series TF Fund (the “Fund”) is a separate non-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”) (formerly known as Legg Mason Partners Fund Advisor, LLC (“LMPFA”) prior to November 30, 2023) 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-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. 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

Western Asset SMASh Series TF Fund 2024 Annual Report

Notes to financial statements (cont’d)

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 generated by market transactions involving identical or comparable securities. The income approach uses valuation techniques to discount estimated future cash flows to present value.

Western Asset SMASh Series TF Fund 2024 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:

(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

Western Asset SMASh Series TF Fund 2024 Annual Report

Notes to financial statements (cont’d)

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 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 29, 2024, the average daily amount of floating rate notes outstanding was $846,694 and weighted average interest rate was 4.00%.

(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

Western Asset SMASh Series TF Fund 2024 Annual Report

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.

(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

Western Asset SMASh Series TF Fund 2024 Annual Report

Notes to financial statements (cont’d)

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 February 29, 2024, 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 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.

(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.

Western Asset SMASh Series TF Fund 2024 Annual Report

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.

(j) 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. During the current year, the Fund had no reclassifications.

2. Investment management agreement and other transactions with affiliates

FTFA is the Fund’s investment manager. Western Asset Management Company, LLC (“Western Asset”) is the Fund’s subadviser. FTFA and Western Asset are indirect, wholly-owned subsidiaries of Franklin Resources, Inc. (“Franklin Resources”).

FTFA and the subadviser 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 subadviser 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 subadviser 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.

During the year ended February 29, 2024, fees waived and/or expenses reimbursed amounted to $145,438.

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. Franklin Templeton Investor Services, LLC (“Investor Services”) serves as the Fund’s shareholder servicing agent and acts as the Fund’s transfer agent and dividend-paying agent. Investor Services is an indirect, wholly-owned subsidiary of Franklin Resources. The Fund pays transfer agent fees to Investor Services for its performance of shareholder servicing obligations. Investor Services charges account-based fees based on the number of individual shareholder accounts, as well as a fixed percentage fee based on the total account-based fees charged. In addition, the Fund reimburses Investor Services for out of pocket expenses incurred. For the year ended February 29, 2024, the Fund incurred transfer agent fees as reported on the Statement of Operations, of which $43 was earned by Investor Services.

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 31, 2025.

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.

Opinion on the Financial Statements

ITEM 4.

PRINCIPAL ACCOUNTANT FEES AND SERVICES.

a) Audit Fees. The aggregate fees billed in the last two fiscal years ending February 28, 2023 and February 29, 2024 (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 $149,262 in February 28, 2023 and $149,262 in February 29, 2024.

b) Audit-Related Fees. The aggregate fees billed in the Reporting Period 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, 2023 and $0 in February 29, 2024.

(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, 2023 and $40,000 in February 29, 2024. 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 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, other than the services reported in paragraphs (a) through (c) for the Item 4 for the Legg Mason Partners Institutional Trust were $0 in February 28, 2023 and $0 in February 29, 2024.

All Other Fees. There were no other non-audit services rendered by the Auditor to Franklin Templeton Fund Adviser, LLC (“FTFA”), and any entity controlling, controlled by or under common control with FTFA that provided ongoing services to Legg Mason Partners Institutional Trust requiring pre-approval by the Audit Committee in the Reporting Period.

(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 FTFA 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 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 any service providers controlling, controlled by or under common control with the Adviser that provide ongoing services to the Fund (“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 Legg Mason Partners Institutional Trust, FTFA and any entity controlling, controlled by, or under common control with FTFA that provides ongoing services to Legg Mason Partners Institutional Trust during the reporting period were $350,359 in February 28, 2023 and $342,635 in February 29, 2024.

(h) Yes. Legg Mason Partners Institutional Trust’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 Accountant’s independence. All services provided by the Auditor to the Legg Mason Partners Institutional Trust or to Service Affiliates, which were required to be pre-approved, were pre-approved as required.

(i) Not applicable.

(j) Not applicable.
