   II ClearBridge Small Cap Value Fund

Letter from the president

Dear Shareholder,

We are pleased to provide the semi-annual report of ClearBridge Small Cap Value Fund for the six-month reporting period ended March 31, 2024. Please read on for Fund performance information during the Fund’s reporting period.

Subsequent event notice

The Board of Trustees, on behalf of the Fund (the “Target Fund”), has approved a reorganization pursuant to which the Target Fund’s assets would be acquired, and its liabilities would be assumed, by ClearBridge Small Cap Fund (the “Acquiring Fund”), a series of Legg Mason Global Asset Management Trust, in exchange for shares of the Acquiring Fund (the “Reorganization”). The Target Fund would then be terminated, and shares of the Acquiring Fund would be distributed to Target Fund shareholders.

The completion of the Reorganization is subject to a number of conditions, but the Reorganization does not require the approval of shareholders. The Reorganization is expected to be completed on or about September 6, 2024, but the Reorganization may occur on such later date as the parties may agree. Effective at the close of market on or about June 24, 2024, the Target Fund will be closed to all new investors except as noted below. Investors who have an open and funded account on June 24 will be able to continue to invest in the Target Fund through exchanges and additional purchases after such date. The following categories of investors will continue to be able to open new accounts in the Target Fund after the close of market on June 24: (1) clients of discretionary investment allocation programs where such programs had investments in the Target Fund prior to the close of market on June 24; and (2) Employer Sponsored Retirement Plans or benefit plans and their participants where the Target Fund was available to participants prior to the close of market on June 24. Effective after the close of market on or about September 4, 2024, the Target Fund will not accept any additional purchases or exchanges. The Target Fund reserves the right to change this policy at any time. For more information, please see the Target Fund’s prospectus supplement dated May 6, 2024.

As always, we remain committed to providing you with excellent service and a full spectrum of investment choices. We also remain committed to supplementing the support you receive from your financial advisor. One way we accomplish this is through our website, www.franklintempleton.com. Here you can gain immediate access to market and investment information, including:

Performance review

For the six months ended March 31, 2024, Class A shares of ClearBridge Small Cap Value Fund, excluding sales charges, returned 14.20%. The Fund’s unmanaged benchmark, the Russell 2000 Value Indexⁱ, returned 18.60% for the same period.

Performance Snapshot as of March 31, 2024 (unaudited)
(excluding sales charges)	6 months
ClearBridge Small Cap Value Fund:
Class A		14.20	%
Class C		13.79	%
Class I		14.35	%
Class IS		14.44	%
Russell 2000 Value Index		18.60	%

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 and investment returns 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 visit our website at www.franklintempleton.com.

All share class returns assume the reinvestment of all distributions, including returns of capital, if any, at net asset value and the deduction of all Fund expenses. Returns have not been adjusted to include sales charges that may apply or the deduction of taxes that a shareholder would pay on Fund distributions. If sales charges were reflected, the performance quoted would be lower. Performance figures for periods shorter than one year represent cumulative figures and are not annualized.

Fund performance figures reflect fee waivers and/or expense reimbursements, without which the performance would have been lower.

Total Annual Operating Expenses (unaudited)

As of the Fund’s current prospectus dated January 31, 2024, the gross total annual fund operating expense ratios for Class A, Class C, Class I and Class IS shares were 1.36%, 2.10%, 1.06% and 0.98%, respectively.

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.

As a result of expense limitation arrangements, the ratio of total annual fund operating expenses, other than interest, brokerage commissions, taxes, extraordinary expenses and acquired fund fees and expenses, to average net assets will not exceed 1.35% for Class A shares, 2.10% for Class C shares, 1.00% for Class I shares and 0.90% for Class IS shares. In addition, the ratio of total annual fund operating expenses for Class IS shares will not exceed the ratio of total annual fund operating expenses for Class I shares. These expense limitation arrangements cannot be terminated prior to December 31, 2025 without the Board of Trustees’ consent. In addition, the manager has agreed to waive the Fund’s management fee to an extent sufficient to offset the net management fee payable in connection with any investment in an affiliated money market fund. This management fee waiver is not subject to the recapture provision discussed below.

ClearBridge Small Cap Value Fund   V

Performance review (cont’d)

The manager is permitted to recapture amounts waived and/or reimbursed to a class during the same fiscal year if the class’ total annual operating expenses have fallen to a level below the expense limitation (“expense cap”) in effect at the time the fees were earned or the expenses incurred. In no case will the manager recapture any amount that would result, on any particular business day of the Fund, in the class’ total annual fund operating expenses exceeding the expense cap or any other lower limit then in effect.

As always, thank you for your confidence in our stewardship of your assets.

Sincerely,

Jane Trust, CFA

RISKS: Equity securities are subject to market and price fluctuations. Stocks of small capitalization companies may involve a higher degree of risk and volatility than stocks of larger capitalization companies. Value stocks may underperform the overall equity market while the market concentrates on growth stocks. The Fund’s investments in securities of foreign issuers or issuers with significant exposure to foreign markets involve additional risk as compared to investments in U.S. securities or issuers with predominantly domestic exposure, such as less liquid, less transparent, less regulated and more volatile markets. The value of the Fund’s investments may decline because of factors affecting the particular issuer as well as foreign markets and issuers generally, such as unfavorable or unsuccessful government actions, reduction of government or central bank support, inadequate accounting standards, lack of information and political, economic, financial or social instability. 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.

All investments are subject to risk including the possible loss of principal. Past performance is no guarantee of future results. All index performance reflects no deduction for fees, expenses or taxes. Please note that an investor cannot invest directly in an index.

   VI ClearBridge Small Cap Value Fund

ⁱ  The Russell 2000 Value Index measures the performance of those Russell 2000 Index companies with lower price- to-book ratios and lower forecasted growth values. (A price-to-book ratio is the price of a stock compared to the difference between a company’s assets and liabilities). The Russell 2000 Index measures the performance of the small-cap segment of the U.S. equity universe. The Russell 2000 is a subset of the Russell 3000 Index representing approximately 10% of the total market capitalization of that index. It includes approximately 2,000 of the smallest securities based on a combination of their market cap and current index membership. The Russell 3000 Index measures the performance of the 3,000 largest U.S. companies based on total market capitalization, which represents approximately 98% of the U.S. equity market.

Fund expenses (unaudited)

Example

As a shareholder of the Fund, you may incur two types of costs: (1) transaction costs, including front-end and back-end sales charges (loads) on purchase payments; and (2) ongoing costs, including management fees; service and/or distribution (12b-1) fees; 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 October 1, 2023 and held for the six months ended March 31, 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, such as front-end or back-end sales charges (loads). 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.

   2 ClearBridge Small Cap Value Fund 2024 Semi-Annual Report

¹  For the six months ended March 31, 2024.

²  Assumes the reinvestment of all distributions, including returns of capital, if any, at net asset value and does not reflect the deduction of the applicable sales charge with respect to Class A shares or the applicable contingent deferred sales charge (“CDSC”) with respect to Class C shares. Total return is not annualized, as it may not be representative of the total return for the year. Performance figures may reflect compensating balance arrangements, fee waivers and/or expense reimbursements. In the absence of compensating balance arrangements, fee waivers and/or expense reimbursements, the total return would have been lower. Past performance is no guarantee of future results.

³  Expenses (net of compensating balance arrangements, fee waivers and/or expense reimbursements) are equal to each class’ respective 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 (183), then divided by 366.

Notes to financial statements (unaudited)

1. Organization and significant accounting policies

ClearBridge Small Cap Value Fund (the “Fund”) is a separate diversified investment series of Legg Mason Partners Investment Trust (the “Trust”). The Trust, a Maryland statutory trust, is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company.

The Fund 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. 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. 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. 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 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

ClearBridge Small Cap Value Fund 2024 Semi-Annual Report   17

Notes to financial statements (unaudited) (cont’d)

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.

   18 ClearBridge Small Cap Value Fund 2024 Semi-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:

ASSETS
Description	Quoted Prices (Level 1)		Other Significant Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total
Common Stocks†	$	115,956,652		—		—	$	115,956,652
Short-Term Investments†		1,478,687		—		—		1,478,687
Total Investments	$	117,435,339		—		—	$	117,435,339

† See Schedule of Investments for additional detailed categorizations.

(b) Foreign currency translation. Investment securities and other assets and liabilities denominated in foreign currencies are translated into U.S. dollar amounts based upon prevailing exchange rates on the date of valuation. Purchases and sales of investment securities and income and expense items denominated in foreign currencies are translated into U.S. dollar amounts based upon prevailing exchange rates on the respective dates of such transactions.

The Fund does not isolate that portion of the results of operations resulting from fluctuations in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held. Such fluctuations are included with the net realized and unrealized gain or loss on investments.

Net realized foreign exchange gains or losses arise from sales of foreign currencies, including gains and losses on forward foreign currency contracts, currency gains or losses realized between the trade and settlement dates on securities transactions, and the difference between the amounts of dividends, interest, and foreign withholding taxes recorded on the Fund’s books and the U.S. dollar equivalent of the amounts actually received or paid. Net unrealized foreign exchange gains and losses arise from changes in

ClearBridge Small Cap Value Fund 2024 Semi-Annual Report   19

Notes to financial statements (unaudited) (cont’d)

the values of assets and liabilities, other than investments in securities, on the date of valuation, resulting from changes in exchange rates.

Foreign security and currency transactions may involve certain considerations and risks not typically associated with those of U.S. dollar denominated transactions as a result of, among other factors, the possibility of lower levels of governmental supervision and regulation of foreign securities markets and the possibility of political or economic instability.

(c) 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.

(d) 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. Dividend income is recorded on the ex-dividend date for dividends received in cash and/or securities. Foreign dividend income is recorded on the ex-dividend date or as soon as practicable after the Fund determines the existence of a dividend declaration after exercising reasonable due diligence. 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.

(e) REIT distributions. The character of distributions received from Real Estate Investment Trusts (‘‘REITs’’) held by the Fund is generally comprised of net investment income, capital gains, and return of capital. It is the policy of the Fund to estimate the character of distributions received from underlying REITs based on historical data provided by the REITs. After each calendar year end, REITs report the actual tax character of these distributions. Differences between the estimated and actual amounts reported by the REITs are reflected in the Fund’s records in the year in which they are reported by the REITs by adjusting related investment cost basis, capital gains and income, as necessary.

(f) Distributions to shareholders. Distributions from net investment income and distributions of net realized gains, if any, are declared at least annually. Distributions to

   20 ClearBridge Small Cap Value Fund 2024 Semi-Annual Report

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.

(g) Share class accounting. Investment income, common expenses and realized/ unrealized gains (losses) on investments are allocated to the various classes of the Fund on the basis of daily net assets of each class. Fees relating to a specific class are charged directly to that share class.

(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.

Management has analyzed the Fund’s tax positions taken on income tax returns for all open tax years and has concluded that as of September 30, 2023, 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.

2. Investment management agreement and other transactions with affiliates

Franklin Templeton Fund Adviser, LLC (“FTFA”) (formerly known as Legg Mason Partners Fund Advisor, LLC prior to November 30, 2023) is the Fund’s investment manager and ClearBridge Investments, LLC (“ClearBridge”) is the Fund’s subadviser. Western Asset Management Company, LLC (“Western Asset”) manages the portion of the Fund’s cash and short-term instruments allocated to it. FTFA, ClearBridge and Western Asset are indirect, wholly-owned subsidiaries of Franklin Resources, Inc. (“Franklin Resources”).

Under the investment management agreement, the Fund pays an investment management fee, calculated daily and paid monthly, at an annual rate of 0.75% of the Fund’s average daily net assets.

FTFA provides administrative and certain oversight services to the Fund. FTFA delegates to the subadviser the day-to-day portfolio management of the Fund, except for the management of the portion of the Fund’s cash and short-term instruments allocated to

ClearBridge Small Cap Value Fund 2024 Semi-Annual Report   21

Notes to financial statements (unaudited) (cont’d)

Western Asset. For its services, FTFA pays ClearBridge a fee monthly, at an annual rate equal to 70% of the net management fee it receives from the Fund. For Western Asset’s services to the Fund, FTFA pays Western Asset monthly 0.02% of the portion of the Fund’s average daily net assets that are allocated to Western Asset by FTFA.

As a result of expense limitation arrangements between the Fund and FTFA, the ratio of total annual fund operating expenses, other than interest, brokerage commissions, taxes, extraordinary expenses and acquired fund fees and expenses, to average net assets of Class A, Class C, Class I and Class IS shares did not exceed 1.35%, 2.10%, 1.00% and 0.90%, respectively. In addition, the ratio of total annual fund operating expenses for Class IS shares did not exceed the ratio of total annual fund operating expenses for Class I shares. These expense limitation arrangements cannot be terminated prior to December 31, 2025 without the Board of Trustees’ consent. In addition, the manager has agreed to waive the Fund’s management fee to an extent sufficient to offset the net management fee payable in connection with any investment in an affiliated money market fund (the “affiliated money market fund waiver”). The affiliated money market fund waiver is not subject to the recapture provision discussed below.

During the six months ended March 31, 2024, fees waived and/or expenses reimbursed amounted to $33,695, which included an affiliated money market fund waiver of $290.

FTFA is permitted to recapture amounts waived and/or reimbursed to a class during the same fiscal year if the class’ total annual fund operating expenses have fallen to a level below the expense limitation (“expense cap”) in effect at the time the fees were earned or the expenses incurred. In no case will FTFA recapture any amount that would result, on any particular business day of the Fund, in the class’ total annual fund operating expenses exceeding the expense cap or any other lower limit then in effect.

Franklin Distributors, LLC (“Franklin Distributors”) serves as the Fund’s sole and exclusive distributor. Franklin Distributors is an indirect, wholly-owned broker-dealer subsidiary of Franklin Resources. 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. Each class of shares of 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, each class reimburses Investor Services for out of pocket expenses incurred. For the six months ended March 31, 2024, the Fund incurred transfer agent fees as reported on the Statement of Operations, of which $7,088 was earned by Investor Services.

There is a maximum initial sales charge of 5.50% for Class A shares. There is a contingent deferred sales charge (“CDSC”) of 1.00% on Class C shares, which applies if redemption occurs within 12 months from purchase payment. In certain cases, Class A shares have a

   22 ClearBridge Small Cap Value Fund 2024 Semi-Annual Report

1.00% CDSC, which applies if redemption occurs within 18 months from purchase payment. This CDSC only applies to those purchases of Class A shares, which, when combined with current holdings of other shares of funds sold by Franklin Distributors, equal or exceed $1,000,000 in the aggregate. These purchases do not incur an initial sales charge.

For the six months ended March 31, 2024, sales charges retained by and CDSCs paid to Franklin Distributors and its affiliates, if any, were as follows:

	Class A		Class C
Sales charges	$	4,803		—

4. Derivative instruments and hedging activities

5. Class specific expenses, waivers and/or expense reimbursements

The Fund has adopted a Rule 12b-1 shareholder services and distribution plan and under that plan the Fund pays service and/or distribution fees with respect to its Class A and Class C shares calculated at the annual rate of 0.25% and 1.00% of the average daily net assets of each class, respectively.

9. Redemption facility

The Fund, together with other U.S. registered and foreign investment funds (collectively, the “Borrowers”) managed by Franklin Resources or its affiliates, is a borrower in a joint syndicated senior unsecured credit facility totaling $2.675 billion (the “Global Credit Facility”). 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 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. These fees are reflected in the Statement of Operations. The Fund did not utilize the Global Credit Facility during the six months ended March 31, 2024.

10. Deferred capital losses

As of September 30, 2023, the Fund had deferred capital losses of $1,976,985, which have no expiration date, that will be available to offset future taxable capital gains.

11. Recent accounting pronouncement

In June 2022, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2022-03, Fair Value Measurement (Topic 820) – Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions. The amendments in the ASU clarify that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, should not be considered in measuring fair value. The ASU is effective for interim and annual reporting periods beginning after December 15, 2023, with the option of early adoption. Management has reviewed the requirements and believes that the adoption of the ASU will not have a material impact on the financial statements.

12. Subsequent event

The Board of Trustees, on behalf of the Fund (the “Target Fund”), has approved a reorganization pursuant to which the Target Fund’s assets would be acquired, and its

   26 ClearBridge Small Cap Value Fund 2024 Semi-Annual Report

liabilities would be assumed, by ClearBridge Small Cap Fund (the “Acquiring Fund”), a series of Legg Mason Global Asset Management Trust, in exchange for shares of the Acquiring Fund (the “Reorganization”). The Target Fund would then be terminated, and shares of the Acquiring Fund would be distributed to Target Fund shareholders.

The completion of the Reorganization is subject to a number of conditions, but the Reorganization does not require the approval of shareholders. The Reorganization is expected to be completed on or about September 6, 2024, but the Reorganization may occur on such later date as the parties may agree. Effective at the close of market on or about June 24, 2024, the Target Fund will be closed to all new investors except as noted below. Investors who have an open and funded account on June 24 will be able to continue to invest in the Target Fund through exchanges and additional purchases after such date. The following categories of investors will continue to be able to open new accounts in the Target Fund after the close of market on June 24: (1) clients of discretionary investment allocation programs where such programs had investments in the Target Fund prior to the close of market on June 24; and (2) Employer Sponsored Retirement Plans or benefit plans and their participants where the Target Fund was available to participants prior to the close of market on June 24. Effective after the close of market on or about September 4, 2024, the Target Fund will not accept any additional purchases or exchanges. The Target Fund reserves the right to change this policy at any time. For more information, please see the Target Fund’s prospectus supplement dated May 6, 2024.
