II Western Asset Inflation Indexed Plus Bond Fund

Investment commentary

Economic review

Economic activity in the U.S. was mixed during the six months ended June 30, 2018 (the “reporting period”). Looking back, the U.S. Department of Commerce reported that revised fourth quarter 2017 U.S. gross domestic product (“GDP”)ⁱ growth was 2.3%. GDP growth then moderated to a revised 2.2% during the first quarter of 2018. Finally, the U.S. Department of Commerce’s initial reading for second quarter 2018 GDP growth — released after the reporting period ended — was 4.1%. The acceleration in GDP growth in the second quarter reflected positive contributions from personal consumption expenditures (“PCE”), exports, nonresidential fixed investment, federal government spending and state and local government spending. These were partly offset by negative contributions from private inventory investment and residential fixed investment. Imports, which are a subtraction in the calculation of GDP, increased.

Job growth in the U.S. was solid overall and supported the economy during the reporting period. When the reporting period ended on June 30, 2018, the unemployment rate was 4.0%, as reported by the U.S. Department of Labor. While the unemployment rate ticked up from 3.8% to 4.0% in June, the increase was largely attributed to an increase in the workforce participation rate. The percentage of longer-term unemployed moved higher during the reporting period. In June 2018, 23.0% of Americans looking for a job had been out of work for more than six months, versus 21.5% when the period began.

Investment commentary (cont’d)

Market review

Q. How did the Federal Reserve Board (the “Fed”)ⁱⁱ respond to the economic environment?

A. The Fed increased the federal funds rateⁱⁱⁱ twice during the reporting period. Looking back, at its meeting that concluded on September 20, 2017 — before the reporting period began — the Fed kept rates on hold, but reiterated its intention to begin reducing its balance sheet. At its meeting that ended on December 13, 2017, the Fed raised rates to a range between 1.25% and 1.50%. As expected, the Fed kept rates on hold at its meeting that concluded on January 31, 2018. However, at its meeting that ended on March 21, 2018, the Fed again raised the federal funds rate, moving it to a range between 1.50% and 1.75%. Finally, at its meeting that concluded on June 13, 2018, the Fed raised the federal funds rate to a range between 1.75% and 2.00%.

Q. Did Treasury yields trend higher or lower during the reporting period?

A. Both short-term and longer-term Treasury yields moved higher during the six-month reporting period ended June 30, 2018. The yield for the two-year Treasury note began the reporting period at 1.89% — the low for the period — and ended the period at 2.52%. The peak for the period of 2.59% occurred on several occasions in May and June 2018. The yield for the ten-year Treasury began the reporting period at 2.40% — the low for the period — and ended the period at 2.85%. The high for the period of 3.11% took place on May 17, 2018.

Q. What factors impacted the spread sectors (non-Treasuries) during the reporting period?

A. Most spread sectors generally posted weak results during the reporting period. Performance fluctuated given changing expectations for global growth, uncertainties regarding future central bank monetary policy and concerns over a global trade war. All told, the broad U.S. bond market, as measured by the Bloomberg Barclays U.S. Aggregate Index^iv, returned -1.62% during the six-month reporting period ended June 30, 2018.

Q. What was the inflationary environment during the reporting period?

A. Inflation remained generally well contained during the reporting period. For the six months ended June 30, 2018, the seasonally unadjusted rate of inflation, as measured by the Consumer Price Index for All Urban Consumers (“CPI-U”)^v, was 2.22%. The CPI-U less food and energy was 1.63% over the same period. Inflation-protected securities generated a small decline during the reporting period. For the six months ended June 30, 2018, the Bloomberg Barclays U.S. Treasury Inflation-Linked Bond Index^vi returned -0.02%.

Q. How did the high-yield bond market perform during the reporting period?

A. The U.S. high-yield bond market, as measured by the Bloomberg Barclays U.S. Corporate High Yield — 2% Issuer Cap Index^vii, returned 0.16% for the six months ended June 30, 2018. The high-yield market posted a modest gain during the first month of the reporting period. Those gains were then erased in February and March 2018.

IV Western Asset Inflation Indexed Plus Bond Fund

This turnaround was triggered by a number of factors, including fears that the Fed may take a more aggressive approach to rate hikes, trade war concerns and high-profile issues in the technology industry. However, the high yield market then rallied in April, was relatively flat in May and moved higher in June 2018.

Performance review

For the six months ended June 30, 2018, Class I shares of Western Asset Inflation Indexed Plus Bond Fund returned -0.43%. The Fund’s unmanaged benchmark, the Bloomberg Barclays U.S. Treasury Inflation-Linked Bond Index, returned -0.02% for the same period. The Lipper Inflation Protected Bond Funds Category Average¹ returned -0.03% over the same time frame.

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, 2018 for Class A, Class C, Class C1, Class FI, Class R, Class I and Class IS shares were 4.40%, 3.88%, 4.09%, 4.43%, 4.25%, 4.87% and 5.02%, respectively. The 30-Day SEC Yield, calculated pursuant to the standard SEC formula, is based on a 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.

¹  Lipper, Inc., a wholly-owned subsidiary of Reuters, provides independent insight on global collective investments. Returns are based on the six-month period ended June 30, 2018, including the reinvestment of all distributions, including returns of capital, if any, calculated among the 249 funds in the Fund’s Lipper category, and excluding sales charges, if any.

Investment commentary (cont’d)

Total Annual Operating Expenses (unaudited)

As of the Fund’s current prospectus dated May 1, 2018, 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 0.71%, 1.32%, 1.14%, 0.67%, 1.01%, 0.39% 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 always, thank you for your confidence in our stewardship of your assets.

Sincerely,

Jane Trust, CFA

RISKS: Fixed-income securities involve interest rate, credit, inflation and reinvestment risks. As interest rates rise, the value of fixed- income securities falls. 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 (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. 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.

The information provided is not intended to be a forecast of future events, a guarantee of future results or investment advice. Views expressed may differ from those of the firm as a whole.

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, 2018 and held for the six months ended June 30, 2018.

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.

¹   For the six months ended June 30, 2018.

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.

Spread duration (unaudited)

Economic exposure — June 30, 2018

Spread duration measures the sensitivity to changes in spreads. The spread over Treasuries is the annual risk-premium demanded by investors to hold non-Treasury securities. Spread duration is quantified as the % change in price resulting from a 100 basis points change in spreads. For a security with positive spread duration, an increase in spreads would result in a price decline and a decline in spreads would result in a price increase. This chart highlights the market sector exposure of the Fund’s sectors relative to the selected benchmark sectors as of the end of the reporting period.

20 Western Asset Inflation Indexed Plus Bond Fund 2018 Semi-Annual Report

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 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 Legg Mason North Atlantic Fund Valuation Committee (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

Western Asset Inflation Indexed Plus Bond Fund 2018 Semi-Annual Report 21

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

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.

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.

† See Schedule of Investments for additional detailed categorizations.

(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 gains or losses in the Statement of Operations and the Fund recognizes a realized gain or loss when the contract is closed.

Western Asset Inflation Indexed Plus Bond Fund 2018 Semi-Annual Report 23

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

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.

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.

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

24 Western Asset Inflation Indexed Plus Bond Fund 2018 Semi-Annual Report

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 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.

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,

Western Asset Inflation Indexed Plus Bond Fund 2018 Semi-Annual Report 25

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

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 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 NAV 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 over-the-counter 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, 2018, the Fund held forward foreign currency contracts with credit related contingent features which had a liability position of $10,736. If a contingent feature in the master agreements would have been triggered, the Fund would have been required to pay this amount to its derivatives counterparties.

(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

26 Western Asset Inflation Indexed Plus Bond Fund 2018 Semi-Annual Report

additional interest income accruals and consider the realizability of interest accrued up to the date of default or credit event.

(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, 2017, 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.

Under the applicable foreign tax laws, a withholding tax may be imposed on interest, dividends and capital gains at various rates.

(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 (formerly Western Asset Management Company) (“Western Asset”), Western Asset Management Company Limited in London (“Western Asset London”), Western Asset Management Company Pte. Ltd. in Singapore (“Western Singapore”) and Western Asset Management Company Ltd in Japan (“Western Japan”) are the Fund’s subadvisers. LMPFA, Western Asset, Western Asset London, Western Singapore and Western Japan are wholly-owned subsidiaries of Legg Mason, Inc. (“Legg Mason”).

Western Asset Inflation Indexed Plus Bond Fund 2018 Semi-Annual Report 27

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

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 Singapore and Western 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, 2019 without the Board of Directors’ consent.

During the six months ended June 30, 2018, fees waived and/or expenses reimbursed amounted to $30.

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 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 operating expenses exceeding the expense cap or any other lower limit then in effect.

Pursuant to these arrangements, at June 30, 2018, the Fund had no remaining fee waivers and/or expense reimbursements subject to recapture by LMPFA. For the six months ended June 30, 2018, LMPFA did not recapture any fees.

Legg Mason Investor Services, LLC (‘‘LMIS’’), a wholly-owned broker-dealer subsidiary of Legg Mason, serves as the Fund’s sole and exclusive distributor.

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. This CDSC only applies to those purchases of Class A shares, which, when combined with current holdings of other shares of funds sold by LMIS, equal or exceed $1,000,000 in the aggregate. These purchases do not incur an initial sales charge.

For the six months ended June 30, 2018, sales charges retained by and CDSCs paid to LMIS and its affiliates, if any, were as follow:

	Class A		Class C		Class C1
Sales charges	$	25		—		—
