Western Asset Mortgage Total Return Fund 2024 Semi-Annual Report

Notes to Financial Statements (unaudited)

1. Organization and significant accounting policies

Western Asset Mortgage Total Return Fund (the “Fund”) is a separate diversified investment series of Legg Mason Partners Income 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. The valuations for fixed income securities (which may include, but are not limited to, corporate, government, municipal, mortgage-backed, collateralized mortgage obligations and asset-backed securities) and certain derivative instruments are typically the prices supplied by independent third party pricing services, which may use market prices or broker/dealer quotations or a variety of valuation techniques and methodologies. The independent third party pricing services typically use inputs that are observable such as issuer details, interest rates, yield curves, prepayment speeds, credit risks/spreads, default rates and quoted prices for similar securities. Investments in open-end funds are valued at the closing net asset value per share of each fund on the day of valuation. Futures contracts are valued daily at the settlement price established by the board of trade or exchange on which they are traded. Equity securities for which market quotations are available are valued at the last reported sales price or official closing price on the primary market or exchange on which they trade. When the Fund holds securities or other assets that are denominated in a foreign currency, the Fund will normally use the currency exchange rates as of 4:00 p.m. (Eastern Time). If independent third party pricing services are unable to supply prices for a portfolio investment, or if the prices supplied are deemed by the manager to be unreliable, the market price may be determined by the manager using quotations from one or more broker/dealers or at the transaction price if the security has recently been purchased and no value has yet been obtained from a pricing service or pricing broker. When reliable prices are not readily available, such as when the value of a security has been significantly affected by events after the close of the exchange or market on which the security is principally traded, but before the Fund calculates its net asset value, the Fund values these securities as determined in accordance with procedures approved by the Fund’s Board of Trustees.

Pursuant to policies adopted by the Board of Trustees, the Fund’s manager has been designated as the valuation designee and is responsible for the oversight of the daily valuation process. The Fund’s manager is assisted by the Global Fund Valuation Committee

Western Asset Mortgage Total Return Fund 2024 Semi-Annual Report

Notes to Financial Statements (unaudited) (cont’d)

(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.

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)

Western Asset Mortgage Total Return Fund 2024 Semi-Annual Report

The inputs or methodologies used to value securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used in valuing the Fund’s assets and liabilities carried at fair value:

ASSETS
Description	Quoted Prices (Level 1)	Other Significant Observable Inputs (Level 2)	Significant Unobservable Inputs (Level 3)	Total

††	Reflects the unrealized appreciation (depreciation) of the instruments.

(b) Futures contracts. The Fund uses futures contracts generally to gain exposure to, or hedge against, changes in interest rates or gain exposure to, or hedge against, changes in certain asset classes. A futures contract represents a commitment for the future purchase or sale of an asset at a specified price on a specified date.

Upon entering into a futures contract, the Fund is required to deposit cash or securities with a broker in an amount equal to a certain percentage of the contract amount. This is known as the ‘‘initial margin’’ and subsequent payments (‘‘variation margin’’) are made or received

Western Asset Mortgage Total Return Fund 2024 Semi-Annual Report

Notes to Financial Statements (unaudited) (cont’d)

by the Fund each day, depending on the daily fluctuation in the value of the contract. For certain futures, including foreign denominated futures, variation margin is not settled daily, but is recorded as a net variation margin payable or receivable. The daily changes in contract value are recorded as unrealized appreciation or depreciation in the Statement of Operations and the Fund recognizes a realized gain or loss when the contract is closed.

Futures contracts involve, to varying degrees, risk of loss in excess of the amounts reflected in the financial statements. In addition, there is the risk that the Fund may not be able to enter into a closing transaction because of an illiquid secondary market.

(c) Stripped securities. The Fund may invest in ‘‘Stripped Securities,’’ a term used collectively for components, or strips, of fixed income securities. Stripped Securities can be principal only securities (“PO”), which are debt obligations that have been stripped of unmatured interest coupons, or interest only securities (“IO”), which are unmatured interest coupons that have been stripped from debt obligations. The market value of Stripped Securities will fluctuate in response to changes in economic conditions, rates of pre-payment, interest rates and the market’s perception of the securities. However, fluctuations in response to interest rates may be greater in Stripped Securities than for debt obligations of comparable maturities that pay interest currently. The amount of fluctuation may increase with a longer period of maturity.

The yield to maturity on IO’s is sensitive to the rate of principal repayments (including prepayments) on the related underlying debt obligation and principal payments may have a material effect on yield to maturity. If the underlying debt obligation experiences greater than anticipated prepayments of principal, the Fund may not fully recoup its initial investment in IO’s.

(d) Securities traded on a to-be-announced basis. The Fund may trade securities on a to-be-announced (“TBA”) basis. In a TBA transaction, the Fund commits to purchasing or selling securities which have not yet been issued by the issuer and for which specific information, such as the face amount, maturity date and underlying pool of investments in U.S. government agency mortgage pass-through securities, is not announced. Securities purchased on a TBA basis are not settled until they are delivered to the Fund. Beginning on the date the Fund enters into a TBA transaction, cash, U.S. government securities or other liquid high-grade debt obligations are segregated in an amount equal in value to the purchase price of the TBA security. These securities are subject to market fluctuations and their current value is determined in the same manner as for other securities.

At June 30, 2024, the Fund held non-cash collateral for TBA securities from JPMorgan Chase & Co. and Morgan Stanley & Co. Inc. in the amounts of $329,897 and $332,106, respectively.

(e) Mortgage dollar rolls. The Fund may enter into mortgage dollar rolls in which the Fund sells mortgage-backed securities for delivery in the current month, realizing a gain or loss, and simultaneously entering into contracts to repurchase substantially similar (same type, coupon and maturity) securities to settle on a specified future date.

Western Asset Mortgage Total Return Fund 2024 Semi-Annual Report

The Fund executes its mortgage dollar rolls entirely in the TBA market, whereby the Fund makes a forward commitment to purchase a security and, instead of accepting delivery, the position is offset by a sale of the security with a simultaneous agreement to repurchase at a future date. The Fund accounts for mortgage dollar rolls as purchases and sales.

The risk of entering into mortgage dollar rolls is that the market value of the securities the Fund is obligated to repurchase under the agreement may decline below the repurchase price. In the event the buyer of securities under a mortgage dollar roll files for bankruptcy or becomes insolvent, the Fund’s use of the proceeds of the mortgage dollar roll may be restricted pending a determination by the counterparty, or its trustee or receiver, whether to enforce the Fund’s obligation to repurchase the securities.

(f) 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 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.

(g) Credit and market risk. Investments in securities that are collateralized by real estate mortgages are subject to certain credit and liquidity risks. When market conditions result in an increase in default rates of the underlying mortgages and the foreclosure values of underlying real estate properties are materially below the outstanding amount of these underlying mortgages, collection of the full amount of accrued interest and principal on these investments may be doubtful. Such market conditions may significantly impair the

Western Asset Mortgage Total Return Fund 2024 Semi-Annual Report

Notes to Financial Statements (unaudited) (cont’d)

value and liquidity of these investments and may result in a lack of correlation between their credit ratings and values.

(h) 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.

(i) 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.

Western Asset Mortgage Total Return Fund 2024 Semi-Annual Report

Under an ISDA Master Agreement, the Fund may, under certain circumstances, offset with the counterparty certain derivative financial instruments’ payables and/or receivables with collateral held and/or posted and create one single net payment. However, absent an event of default by the counterparty or a termination of the agreement, the terms of the ISDA Master Agreements do not result in an offset of reported amounts of financial assets and financial liabilities in the Statement of Assets and Liabilities across transactions between the Fund and the applicable counterparty. The enforceability of the right to offset may vary by jurisdiction.

Collateral requirements differ by type of derivative. Collateral or margin requirements are set by the broker or exchange clearinghouse for exchange traded derivatives while collateral terms are contract specific for OTC traded derivatives. Cash collateral that has been pledged to cover obligations of the Fund under derivative contracts, if any, will be reported separately in the Statement of Assets and Liabilities. Securities pledged as collateral, if any, for the same purpose are noted in the Schedule of Investments.

As of June 30, 2024, the Fund did not have any open OTC derivative transactions with credit related contingent features in a net liability position.

(j) Security transactions and investment income. Security transactions are accounted for on a trade date basis. Interest income (including interest income from payment-in-kind securities) is recorded on the accrual basis. Amortization of premiums and accretion of discounts on debt securities are recorded to interest income over the lives of the respective securities, except for premiums on certain callable debt securities, which are amortized to the earliest call date. Paydown gains and losses on mortgage- and asset-backed securities are recorded as adjustments to interest income. Dividend income is recorded on the ex-dividend date for dividends received in cash and/or securities. The cost of investments sold is determined by use of the specific identification method. To the extent any issuer defaults or a credit event occurs that impacts the issuer, the Fund may halt any additional interest income accruals and consider the realizability of interest accrued up to the date of default or credit event.

(k) Partnership accounting policy. The Fund records its pro rata share of the income (loss) and capital gains (losses), to the extent of distributions it has received, allocated from the underlying partnerships and accordingly adjusts the cost basis of the underlying partnerships for return of capital. These amounts are included in the Fund’s Statement of Operations.

(l) Distributions to shareholders. Distributions from net investment income of the Fund are declared each business day to shareholders of record and are paid monthly. Distributions of net realized gains, if any, are declared at least annually. Distributions to shareholders of the Fund are recorded on the ex-dividend date and are determined in accordance with income tax regulations, which may differ from GAAP.

(m) Share class accounting. Investment income, common expenses and realized/unrealized gains (losses) on investments are allocated to the various classes of the Fund on

Western Asset Mortgage Total Return Fund 2024 Semi-Annual Report

Notes to Financial Statements (unaudited) (cont’d)

the basis of daily net assets of each class. Fees relating to a specific class are charged directly to that share class.

(n) 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.

(o) 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 December 31, 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.

(p) Reclassification. GAAP requires that certain components of net assets be reclassified to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or net asset value per share.

2. Investment management agreement and other transactions with affiliates

Franklin Templeton Fund Adviser, LLC (“FTFA”) is the Fund’s investment manager and 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”).

Under the investment management agreement, the Fund pays an investment management fee, calculated daily and paid monthly, in accordance with the following breakpoint schedule:

Average Daily Net Assets	Annual Rate
First $4 billion	0.500 %
Next $2 billion	0.450
Next $2 billion	0.400
Over $8 billion	0.350

FTFA provides administrative and certain oversight services to the Fund. FTFA delegates to the subadviser the day-to-day portfolio management of the Fund. For its services, FTFA pays Western Asset monthly 70% of the net management fee it receives from the Fund.

As a result of expense limitation arrangements between the Fund and FTFA, the ratio of total annual fund operating expenses, other than interest, brokerage, taxes, extraordinary

Western Asset Mortgage Total Return Fund 2024 Semi-Annual Report

expenses and acquired fund fees and expenses, to average net assets of Class C, Class C1, Class I and Class IS shares did not exceed 1.75%, 1.75%, 0.70% and 0.60%, 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 and the ratio of total annual fund operating expenses for Class 1 shares did not exceed the ratio of total annual fund operating expenses for Class A 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 June 30, 2024, fees waived and/or expenses reimbursed amounted to $564, which included an affiliated money market fund waiver of $464.

FTFA is permitted to recapture amounts waived and/or reimbursed to a class within two years after the fiscal year in which FTFA earned the fee or incurred the expense 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.

Pursuant to these arrangements, at June 30, 2024, the Fund had remaining fee waivers and/or expense reimbursements subject to recapture by FTFA and respective dates of expiration as follows:

	Class C1
Expires December 31, 2024	$416
Expires December 31, 2025	289
Expires December 31, 2026	100
Total fee waivers/expense reimbursements subject to recapture	$805

For the six months ended June 30, 2024, FTFA did not recapture any fees.

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

Western Asset Mortgage Total Return Fund 2024 Semi-Annual Report

Notes to Financial Statements (unaudited) (cont’d)

June 30, 2024, the Fund incurred transfer agent fees as reported on the Statement of Operations, of which $7,992 was earned by Investor Services.

There is a maximum initial sales charge of 3.75% for Class A shares. There is a contingent deferred sales charge (“CDSC”) of 1.00% on Class C and Class C1 shares which applies if redemption occurs within 12 months from purchase payment. In certain cases, Class A shares have a 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 $500,000 in the aggregate. These purchases do not incur an initial sales charge.

For the six months ended June 30, 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	$8,672	—
CDSCs	1,815	$25

All officers and one Trustee of the Trust are employees of Franklin Resources or its affiliates and do not receive compensation from the Trust.

3. Investments

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”).

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 June 30, 2024.

11. Recent accounting pronouncement

In March 2020, the FASB issued Accounting Standards Update (ASU) No. 2020-04, Reference Rate Reform (Topic 848) – Facilitation of the Effects of Reference Rate Reform on Financial Reporting. In January 2021 and December 2022, the FASB issued ASU No. 2021-01 and ASU No. 2022-06, with further amendments to Topic 848. The amendments in the ASUs provide optional temporary accounting recognition and financial reporting relief from the effect of certain types of contract modifications due to the planned discontinuation of the London Interbank Offered Rate (LIBOR) and other interbank-offered based reference rates as of the end of 2021 for certain LIBOR settings and 2023 for the remainder. The ASUs are effective for certain reference rate-related contract modifications that occur during the period March 12, 2020, through December 31, 2024. Management has reviewed the requirements and believes the adoption of these ASUs will not have a material impact on the financial statements.

Western Asset Mortgage Total Return Fund

Board Approval of Management and

Subadvisory Agreements (unaudited)

The Executive and Contracts Committee of the Board of Trustees (the “Executive and Contracts Committee”) considered the Management Agreement between the Trust and Franklin Templeton Fund Adviser, LLC (“FTFA”) (formerly known as Legg Mason Partners Fund Advisor, LLC) with respect to the Fund and the subadvisory agreement between FTFA and Western Asset Management Company, LLC (“Western Asset” or the “Subadviser”, and together with FTFA, the “Advisers”) with respect to the Fund (collectively, the “Agreements”) at a meeting held on April 30, 2024. At an in-person meeting held on May 16, 2024, the Executive and Contracts Committee reported to the full Board of Trustees their considerations and recommendation with respect to the Agreements, and the Board of Trustees, including a majority of the Independent Trustees, considered and approved renewal of the Agreements.

In arriving at their decision to approve the renewal of the Agreements, the Trustees met with representatives of the Advisers, including relevant investment advisory personnel; considered a variety of information prepared by the Advisers, materials provided by Broadridge and advice and materials provided by counsel to the Independent Trustees; reviewed performance and expense information for peer groups of comparable funds selected by Broadridge (the “Performance Universe”) and certain other comparable products available from Western Asset or affiliates of Western Asset, including separate accounts managed by Western Asset; and requested and reviewed additional information as necessary. These reviews were in addition to information obtained by the Trustees at their regular quarterly meetings (and various committee meetings) with respect to the Fund’s performance and other relevant matters and related discussions with the Advisers’ personnel. The information received and considered by the Board both in conjunction with the May meeting and at prior meetings was both written and oral. With respect to the Broadridge materials, the Board was provided with a description of the methodology used to determine the similarity of the Fund with the funds included in the Performance Universe. It was noted that while the Board found the Broadridge data generally useful they recognized its limitations, including that the data may vary depending on the end date selected and that the results of the performance comparisons may vary depending on the selection of the peer group and its composition over time.

As part of their review, the Trustees examined FTFA’s ability to provide high quality oversight and administrative and shareholder support services to the Fund and the Subadviser’s ability to provide high quality investment management services to the Fund. The Trustees considered the experience of FTFA’s personnel in providing the types of services that FTFA is responsible for providing to the Fund; the ability of FTFA to attract and retain capable personnel; and the capability and integrity of FTFA’s senior management and staff. The Trustees also considered the investment philosophy and research and decision-making processes of the Subadviser; the experience of their key advisory personnel responsible for management of the Fund; the ability of the Subadviser to attract and retain

Western Asset Mortgage Total Return Fund

Board Approval of Management and

Subadvisory Agreements (unaudited) (cont’d)

capable research and advisory personnel; the risks to the Advisers associated with sponsoring the Fund (such as entrepreneurial, operational, reputational, litigation and regulatory risk), as well as FTFA’s and the Subadviser’s risk management processes; the capability and integrity of the Advisers’ senior management and staff; and the level of skill required to manage the Fund. In addition, the Trustees reviewed the quality of the Advisers’ services with respect to regulatory compliance and compliance with the investment policies of the Fund, and conditions that might affect the Advisers’ ability to provide high quality services to the Fund in the future, including their business reputations, financial conditions and operational stabilities. Based on the foregoing, the Trustees concluded that the Subadviser’s investment process, research capabilities and philosophy were well suited to the Fund given its investment objectives and policies, and that the Advisers would be able to meet any reasonably foreseeable obligations under the Agreements.

The Board reviewed the qualifications, backgrounds and responsibilities of FTFA’s and Western Asset’s senior personnel and the team of investment professionals primarily responsible for the day-to-day portfolio management of the Fund. The Board also considered, based on its knowledge of FTFA and its affiliates, the financial resources of Franklin Resources, Inc., the parent organization of the Advisers. The Board recognized the importance of having a fund manager with significant resources.

In reviewing the quality of the services provided to the Fund, the Trustees also reviewed comparisons of the performance of the Fund to the performance of certain comparable funds and to its investment benchmark over the 1-, 3-, 5-, and 10-year periods ended December 31, 2023. The information comparing the Fund’s performance to that of its Performance Universe, consisting of all funds (including the Fund) classified as retail and institutional U.S. mortgage funds by Broadridge, showed, among other data, that the Fund’s performance for the 10-year period ended December 31, 2023 was above the median, the Fund’s performance for the 3-year period ended December 31, 2023 was slightly below the median and the Fund’s performance for the 1- and 5-year periods ended December 31, 2023 was below the median. The Board noted that the Fund’s performance exceeded the performance of its benchmark index for the 10-year period ended December 31, 2023 and trailed the performance of its benchmark index for the 1-, 3-, and 5-year periods ended December 31, 2023. The Board considered the factors involved in the Fund’s performance relative to the performance of its investment benchmark and Performance Universe.

The Trustees also considered the management fee payable by the Fund to FTFA, total expenses payable by the Fund and the fee that FTFA pays to the Subadviser. They reviewed information concerning management fees paid to investment advisers of similarly managed funds as well as fees paid by Western Asset’s other clients, including separate accounts managed by Western Asset. The Trustees also noted that the Fund does not pay any management fees directly to the Subadviser because FTFA pays the Subadviser for services

Western Asset Mortgage Total Return Fund

provided to the Fund out of the management fee FTFA receives from the Fund. The information comparing the Fund’s Contractual and Actual Management Fees as well as its actual total expense ratio to its peer group, consisting of a group of institutional U.S. mortgage funds (including the Fund) chosen by Broadridge to be comparable to the Fund, showed that the Fund’s Contractual Management Fee and Actual Management Fee were above the median. The Board noted that the Fund’s actual total expense ratio was above the median. The Board also considered that the current limitation on the Fund’s expenses is expected to continue through December 2025.

The Trustees further evaluated the benefits of the advisory relationship to the Advisers, including, among others, the profitability of the relationship to the Advisers; the direct and indirect benefits that the Advisers may receive from their relationships with the Fund, including the “fallout benefits,” such as reputational value derived from serving as investment adviser to the Fund; and the affiliation between the Advisers and certain other service providers for the Fund. In that connection, the Board considered that the ancillary benefits that the Advisers receive were reasonable. The Trustees noted that Western Asset does not have soft dollar arrangements.

Finally, the Trustees considered, in light of the profitability information provided by the Advisers, the extent to which economies of scale would be realized by the Advisers as the assets of the Fund grow. The Board noted that the Fund’s Contractual Management Fee and Actual Management Fee were above the median of the peer group. The Board also noted the size of the Fund.

In their deliberations with respect to these matters, the Independent Trustees were advised by their independent counsel, who is independent, within the meaning of the Securities and Exchange Commission rules regarding the independence of counsel, of the Advisers. The Independent Trustees weighed the foregoing matters in light of the advice given to them by their independent counsel as to the law applicable to the review of investment advisory contracts. In arriving at a decision, the Trustees, including the Independent Trustees, did not identify any single matter as all-important or controlling, and each Trustee may have attributed different weight to the various factors in evaluating the Agreements. The foregoing summary does not detail all the matters considered. The Trustees judged the terms and conditions of the Agreements, including the investment advisory fees, in light of all of the surrounding circumstances.

Based upon their review, the Trustees, including all of the Independent Trustees, determined, in the exercise of their business judgment, that they were satisfied with the quality of investment advisory services being provided by the Advisers; that the fees to be paid to the Advisers under the Agreements were fair and reasonable given the scope and quality of the services rendered by the Advisers; and that approval of the Agreements was in the best interest of the Fund and its shareholders.
