INFLATION INDEXED PLUS BOND FUND

The Fund intends to no longer mail paper copies of the Fund’s shareholder reports like this one, unless you specifically request paper copies of the reports from the Fund or from your Service Agent or financial intermediary (such as a broker-dealer or bank). Instead, the reports will be made available on a website, and you will be notified by mail each time a report is posted and provided with a website link to access the report.

If you already elected to receive shareholder reports electronically (“e-delivery”), you will not be affected by this change and you need not take any action. If you have not already elected e-delivery, you may elect to receive shareholder reports and other communications from the Fund electronically by contacting your Service Agent or, if you are a direct shareholder with the Fund, by calling 1-877-721-1926.

You may elect to receive all future reports in paper free of charge. If you invest through a Service Agent, you can contact your Service Agent to request that you continue to receive paper copies of your shareholder reports. That election will apply to all Legg Mason Funds held in your account at that Service Agent. If you are a direct shareholder with the Fund, you can call the Fund at 1-877-721-1926, or write to the Fund by regular mail at Legg Mason Funds, P.O. Box 9699, Providence, RI 02940-9699 or by express, certified or registered mail to Legg Mason Funds, 4400 Computer Drive, Westborough, MA 01581 to let the Fund know you wish to continue receiving paper copies of your shareholder reports. That election will apply to all Legg Mason Funds held in your account held directly with the fund complex.

   II  Western Asset Inflation Indexed Plus Bond Fund

Performance review

For the six months ended June 30, 2021, Class I shares of Western Asset Inflation Indexed Plus Bond Fund returned 1.47%. The Fund’s unmanaged benchmark, the Bloomberg Barclays U.S. Treasury Inflation-Linked Bond Indexⁱ, returned 1.73% for the same period. The Lipper Inflation Protected Bond Funds Category Averageⁱⁱ returned 1.99% over the same time frame.

Performance Snapshot as of June 30, 2021 (unaudited)
(excluding sales charges)	6 months
Western Asset Inflation Indexed Plus Bond Fund:
Class A		1.22	%
Class C		0.96	%
Class C1		0.97	%
Class FI		1.36	%
Class R		1.08	%
Class I		1.47	%
Class IS		1.50	%
Bloomberg Barclays U.S. Treasury Inflation-Linked Bond Index		1.73	%
Lipper Inflation Protected Bond Funds Category Average		1.99	%

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 visit our website at www.leggmason.com/mutualfunds.

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.

The 30-Day SEC Yields for the period ended June 30, 2021 for Class A, Class C, Class C1, Class FI, Class R, Class I and Class IS shares were 4.83%, 4.33%, 4.26%, 5.09%, 4.51%, 5.37% and 5.44%, respectively. Absent fee waiver and/or expense reimbursements, the 30-Day SEC Yields for Class C1 and Class R shares would have been 3.71% and 4.48%, respectively. The 30-Day SEC Yield, calculated pursuant to the standard SEC formula, is based on the Fund’s investments over an annualized trailing 30-day period, and not on the distributions paid by the Fund, which may differ. The 30-Day SEC Yield includes adjustments for inflation to both U.S. and foreign portfolio securities that are linked to inflation indices. Please note, inflation adjustments to U.S. securities often occur at different intervals than foreign securities. These adjustments can cause the SEC Yield to change substantially from month-to-month. Increases in the inflation rate may result in the Fund reporting an exceptionally high yield which may not be repeated.

Western Asset Inflation Indexed Plus Bond Fund    III 

Performance review (cont’d)

 Total Annual Operating Expenses (unaudited)

As of the Fund’s current prospectus dated May 1, 2021, the gross total annual fund operating expense ratios for Class A, Class C, Class C1, Class FI, Class R, Class I and Class IS shares were 0.65%, 1.43%, 2.24%, 0.73%, 1.06%, 0.35% and 0.27%, 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, deferred organizational expenses and acquired fund fees and expenses, to average net assets will not exceed 0.90% for Class A shares, 1.65% for Class C shares, 1.40% for Class C1 shares, 0.85% for Class FI shares and 1.15% for Class R 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, 2022 without the Board of Directors’ 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.

The manager is permitted to recapture amounts waived and/or reimbursed to a class within two years after the fiscal year in which the manger 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 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

President and Chief Executive Officer

RISKS: Fixed income securities involve interest rate, credit, inflation and reinvestment risks. As interest rates rise, the value of fixed income securities falls, thereby reducing the value of the Fund’s share price. Derivatives, such as options, futures and swaps, 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. Risks of high-yield securities

   IV  Western Asset Inflation Indexed Plus Bond Fund

(commonly known as “junk” bonds) include greater price volatility, illiquidity and possibility of default. The Fund may be subject to interest rate, income and deflation risks. Changes in inflation will cause the Fund’s income to fluctuate, sometimes substantially. Periods of deflation may adversely affect the Fund’s net asset value. International investments are subject to special risks, including currency fluctuations and social, economic and political uncertainties, which could increase volatility. These risks are magnified in emerging markets. Emerging market countries tend to have economic, political and legal systems that are less developed and are less stable than those of more developed countries. Asset-backed, mortgage-backed or mortgage related securities are subject to prepayment and extension risks. 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.

ⁱ The Bloomberg Barclays U.S. Treasury Inflation-Linked Bond Index represents an unmanaged market index made up of U.S. Treasury Inflation-Linked Index securities.

ⁱⁱ Lipper, Inc., a wholly-owned subsidiary of Refinitiv, provides independent insight on global collective investments. Returns are based on the six-month period ended June 30, 2021, including the reinvestment of all distributions, including returns of capital, if any, calculated among the 203 funds in the Fund’s Lipper category, and excluding sales charges, if any.

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 January 1, 2021 and held for the six months ended June 30, 2021.

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 Western Asset Inflation Indexed Plus Bond Fund 2021 Semi-Annual Report

¹   For the six months ended June 30, 2021.

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 (181), then divided by 365.

Western Asset Inflation Indexed Plus Bond Fund 2021 Semi-Annual Report    19 

Notes to financial statements (unaudited)

1. Organization and significant accounting policies

Western Asset Inflation Indexed Plus Bond Fund (the “Fund”) is a separate diversified investment series of Western Asset Funds, Inc. (the “Corporation”). The Corporation, a Maryland Statutory Corporation, is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company.

The following are significant accounting policies consistently followed by the Fund and are in conformity with U.S. generally accepted accounting principles (“GAAP”). 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 Directors.

The Board of Directors is responsible for the valuation process and has delegated the supervision of the daily valuation process to the Global Fund Valuation Committee (formerly known as Legg Mason North Atlantic Fund Valuation Committee prior to March 1, 2021) (the “Valuation Committee”). The Valuation Committee, pursuant to the policies adopted by the Board of Directors, is responsible for making fair value determinations, evaluating the effectiveness of the Fund’s pricing policies, and reporting to the Board of Directors. 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.

   20  Western Asset Inflation Indexed Plus Bond Fund 2021 Semi-Annual Report

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 Directors, 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 Directors 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 — 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.

†† 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 cash equivalents 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.

   22  Western Asset Inflation Indexed Plus Bond Fund 2021 Semi-Annual Report

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) Forward foreign currency contracts. The Fund enters into a forward foreign currency contract to hedge exposure of bond positions or in an attempt to increase the Fund’s return. A forward foreign currency contract is an agreement between two parties to buy and sell a currency at a set price with delivery and settlement at a future date. The contract is marked-to-market daily and the change in value is recorded by the Fund as an unrealized gain or loss. When a forward foreign currency contract is closed, through either delivery or offset by entering into another forward foreign currency contract, the Fund recognizes a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value of the contract at the time it is closed.

Non-deliverable forward foreign currency exchange contracts are settled with the counterparty in cash without the delivery of foreign currency.

Forward foreign currency contracts involve elements of market risk in excess of the amounts reflected on the Statement of Assets and Liabilities. The Fund bears the risk of an unfavorable change in the foreign exchange rate underlying the forward foreign currency contract. Risks may also arise upon entering into these contracts from the potential inability of the counterparties to meet the terms of their contracts.

(d) Inflation-indexed bonds. Inflation-indexed bonds are fixed income securities whose principal value or interest rate is periodically adjusted according to the rate of inflation. As the index measuring inflation changes, the principal value or interest rate of inflation-indexed bonds will be adjusted accordingly. Inflation adjustments to the principal amount of inflation-indexed bonds are reflected as an increase or decrease to investment income on the Statement of Operations. Repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed in the case of U.S. Treasury inflation-indexed bonds. For bonds that do not provide a similar guarantee, the adjusted principal value of the bond repaid at maturity may be less than the original principal.

(e) 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.

Western Asset Inflation Indexed Plus Bond Fund 2021 Semi-Annual Report    23 

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

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.

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

(g) 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.

(h) 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.

   24  Western Asset Inflation Indexed Plus Bond Fund 2021 Semi-Annual Report

With exchange traded and centrally cleared derivatives, there is less counterparty risk to the Fund since the exchange or clearinghouse, as counterparty to such instruments, guarantees against a possible default. The clearinghouse stands between the buyer and the seller of the contract; therefore, the credit risk is limited to failure of the clearinghouse. While offset rights may exist under applicable law, the Fund does not have a contractual right of offset against a clearing broker or clearinghouse in the event of a default of the clearing broker or clearinghouse.

The Fund has entered into master agreements, such as an International Swaps and Derivatives Association, Inc. Master Agreement (“ISDA Master Agreement”) or similar agreement, with certain of its derivative counterparties that govern over-the-counter (“OTC”) derivatives and provide for general obligations, representations, agreements, collateral posting terms, netting provisions in the event of default or termination and credit related contingent features. The credit related contingent features include, but are not limited to, a percentage decrease in the Fund’s net assets or net asset value per share over a specified period of time. If these credit related contingent features were triggered, the derivatives counterparty could terminate the positions and demand payment or require additional collateral.

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

Collateral requirements differ by type of derivative. Collateral or margin requirements are set by the broker or exchange clearinghouse for exchange traded derivatives while 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, 2021, the Fund did not have any open OTC derivative transactions with credit related contingent features in a net liability position.

(i) 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), adjusted for amortization of premium and accretion of discount, is recorded on the accrual basis. 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.

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

(j) Distributions to shareholders. Distributions from net investment income of the Fund, if any, are declared and paid on a quarterly basis. 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.

(k) 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.

(l) 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.

(m) 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, 2020, 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.

(n) 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

Legg Mason Partners Fund Advisor, LLC (“LMPFA”) is the Fund’s investment manager. Western Asset Management Company, LLC (“Western Asset”), Western Asset Management Company Limited in London (“Western Asset London”), Western Asset Management Company Pte. Ltd. in Singapore (“Western Asset Singapore”) and Western Asset Management Company Ltd in Japan (“Western Asset Japan”) are the Fund’s subadvisers. LMPFA, Western Asset, Western Asset London, Western Asset Singapore and Western Asset Japan are indirect, wholly-owned subsidiaries of Franklin Resources, Inc. (“Franklin Resources”).

   26  Western Asset Inflation Indexed Plus Bond Fund 2021 Semi-Annual Report

LMPFA provides the Fund with management and administrative services for which the Fund pays a fee, calculated daily and paid monthly, at an annual rate of 0.20% of the Fund’s average daily net assets. For their services, LMPFA pays Western Asset, Western Asset London, Western Asset Singapore and Western Asset Japan monthly all of the management fee that it receives from the Fund.

As a result of expense limitation arrangements between the Fund and LMPFA, the ratio of total annual fund operating expenses, other than interest, brokerage commissions, taxes, extraordinary expenses, deferred organizational expenses and acquired fund fees and expenses, to average net assets of Class A, Class C, Class C1, Class FI and Class R shares did not exceed 0.90%, 1.65%, 1.40%, 0.85% and 1.15%, 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, 2022 without the Board of Directors’ 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, 2021, fees waived and/or expenses reimbursed amounted to $1,311, which included an affiliated money market fund waiver of $1,132.

LMPFA is permitted to recapture amounts waived and/or reimbursed to a class within two years after the fiscal year in which LMPFA 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 LMPFA 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, 2021, the Fund had remaining fee waivers and/or expense reimbursements subject to recapture by LMPFA and respective dates of expiration as follows:

	Class C1		Class R
Expires December 31, 2021		—		—

Expires December 31, 2023		93	$	86
Total fee waivers/expense reimbursements subject to recapture	$	490	$	86

For the six months ended June 30, 2021, LMPFA did not recapture any fees.

Legg Mason Investor Services, LLC (“LMIS”) serves as the Fund’s sole and exclusive distributor. LMIS is an indirect, wholly-owned broker-dealer subsidiary of Franklin Resources. As of July 7, 2021, LMIS was renamed Franklin Distributors, LLC.

There is a maximum initial sales charge of 4.25% 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 1.00% CDSC, which applies if redemption occurs within 18 months from purchase payment.

all or some portion of the six months ended June 30, 2021. The following transactions were effected in such company for the six months ended June 30, 2021.

9. Redemption facility

Effective February 5, 2021, the Fund’s redemption facility (the “Redemption Facility”) was terminated and the Fund and certain other participating funds within the Trust, together with other U.S. registered and foreign investment funds (collectively, the “Borrowers”) managed by LMPFA or Franklin Resources, became borrowers 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 February 4, 2022.

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; there is no upfront fee. Under the Redemption Facility, the Fund had access to the aggregate amount of $485 million prior to February 5, 2021 and the following terms were in effect: the annual commitment fee to maintain the Redemption Facility was 0.15% incurred on the unused portion of the facility and there was an annual upfront fee of 0.06%. The aggregate commitment fees under the Global Credit Facility and Redemption Facility are reflected in the Statement of Operations. The Fund did not utilize the Global Credit Facility nor the Redemption Facility during the six months ended June 30, 2021.

10. Deferred capital losses

As of December 31, 2020, the Fund had deferred capital losses of $1,481,166, which have no expiration date, that will be available to offset future taxable capital gains.

11. Recent accounting pronouncement

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

12. Other matters

The outbreak of the respiratory illness COVID-19 (commonly referred to as “coronavirus”) has continued to rapidly spread around the world, causing considerable uncertainty for the global economy and financial markets. The ultimate economic fallout from the pandemic, and the long-term impact on economies, markets, industries and individual issuers, are not known. The COVID-19 pandemic could adversely affect the value and liquidity of the Fund’s investments, impair the Fund’s ability to satisfy redemption requests, and negatively impact the Fund’s performance. In addition, the outbreak of COVID-19, and measures taken to mitigate its effects, could result in disruptions to the services provided to the Fund by its service providers.

***

The Fund’s investments, payment obligations, and financing terms may be based on floating rates, such as the London Interbank Offered Rate, or “LIBOR,” which is the offered rate for short-term Eurodollar deposits between major international banks. On March 5, 2021, the ICE Benchmark Administration, the administrator of LIBOR, stated that it will cease the publication of (i) the overnight and one-, three-, six- and twelve-month USD LIBOR settings immediately following the LIBOR publication on Friday, June 30, 2023 and (ii) all other LIBOR settings, including the one-week and two-month USD LIBOR settings, immediately following the LIBOR publication on Friday, December 31, 2021. There remains uncertainty regarding the nature of any replacement rate and the impact of the transition from LIBOR on the Fund’s transactions and the financial markets generally. As such, the potential effect of a transition away from LIBOR on the Fund or the Fund’s investments cannot yet be determined.

13. Subsequent event

Subsequent to the period ended June 30, 2021, shareholder redemptions from Class I and Class IS shares exceeded 50% of Class I and Class IS net assets as of June 30, 2021.
