The manager has agreed to waive fees and/or reimburse operating expenses (other than interest, brokerage, taxes, extraordinary expenses and acquired fund fees and expenses) so that the ratio of total annual fund operating expenses will not exceed 0.75% for Class A shares, 1.35% for Class C shares, 0.85% for Class FI shares, and, effective December 1, 2022, 0.50% for Class I shares and 0.47% for Class IS shares, subject to recapture as described below. 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, subject to recapture as described below. These arrangements cannot be terminated prior to December 31, 2024 without the Board of Trustees' consent. The manager is permitted to recapture amounts waived and/or reimbursed to a class within two years after the fiscal year in which the manager earned the fee or incurred the expense if the class' total annual fund operating expenses have fallen to a level below the limits described above. 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 applicable limits described above or any other lower limit then in effect. 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 above.

9	Total annual fund operating expenses after waiving fees and/or reimbursing expenses have been restated to reflect current management fees and expense caps, as applicable.

Example

This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. The example assumes:

●

You invest $10,000 in the fund for the time periods indicated

●

Your investment has a 5% return each year and the fund's operating expenses remain the same (except that any applicable fee waiver or expense reimbursement is reflected only through its expiration date)

●

You reinvest all distributions and dividends without a sales charge

Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Number of years you own your shares ($)
		1 year		3 years		5 years		10 years
Class A (with or without redemption at end of period)		300		461		637		1,144
Class C (with or without redemption at end of period)		134		418		723		1,436
Class FI (with or without redemption at end of period)		87		301		533		1,199
Class I (with or without redemption at end of period)		51		188		337		773
Class IS (with or without redemption at end of period)		48		166		295		671

Portfolio turnover. The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During the most recent fiscal year, the fund's portfolio turnover rate was 10% of the average value of its portfolio.

Principal investment strategies

Under normal circumstances, the fund invests at least 80% of its assets in investment grade "California municipal securities" or other investments with similar economic characteristics. California municipal securities are securities the interest on which is exempt from regular federal income tax and California State personal income taxes. The fund's 80% policy may not be changed without a shareholder vote. Interest on California municipal securities may be subject to the federal alternative minimum tax.

California municipal securities include debt obligations issued by the State of California and its political subdivisions, agencies and public authorities, certain other governmental issuers (such as Puerto Rico, the U.S. Virgin Islands and Guam) and other qualifying issuers. These securities include participation or other interests in municipal securities issued or backed by banks, insurance companies and other financial institutions.

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

The fund focuses on investment grade bonds (that is, securities rated in the Baa/BBB categories or above or, if unrated or deemed to be unrated by the subadviser, determined to be of comparable credit quality by the subadviser) but may invest up to 20% of its assets in below investment grade bonds (commonly known as "high yield" or "junk" bonds).

The fund may invest up to 20% of its assets in unrated securities that the subadviser determines to be equivalent to investment grade.

The fund may invest in securities of any maturity. The fund normally maintains an average effective portfolio maturity of between three and ten years. The average effective portfolio maturity of the fund is a weighted average of all the maturities of the securities in the portfolio, computed by weighting each security's effective maturity, as estimated by the subadviser, by the market value of the security, and any cash in the portfolio. For the purposes of determining the fund's average effective maturity, a security's maturity date will generally be deemed to be the next interest rate reset date for an adjustable rate security or, if earlier, the date of the next demand feature such as a put feature, when the fund would be entitled to receive payment of principal and interest. The subadviser may also take into account estimated future prepayments on securities, such as mortgage-backed securities, with uncertain future cash flows and estimations of call features and similar features and options. These estimates may prove to be incorrect.

The fund may also invest in securities of other open-end or closed-end investment companies, including exchange-traded funds ("ETFs"), that invest primarily in municipal securities.

Instead of, and/or in addition to, investing directly in particular securities, the fund may use instruments such as derivatives, including options, futures contracts and inverse floating rate instruments issued in tender option bond transactions, and other synthetic instruments that are intended to provide economic exposure to the securities or the issuer or to be used as a hedging technique. The fund may use one or more types of these instruments without limit, except that these instruments are taken into account when determining compliance with the fund's 80%

Western Asset Intermediate Maturity California Municipals Fund				5

policy. For additional information regarding derivatives, see "More on the fund's investment strategies, investments and risks-Derivatives" in the Prospectus.

The fund may also engage in a variety of transactions using derivatives in order to change the investment characteristics of its portfolio (such as shortening or lengthening duration) and for other purposes. The fund may leverage its assets by investing proceeds received through tender option bond transactions, which is considered a form of borrowing. See "More on the fund's investment strategies, investments and risks-Tender option bonds" in the Prospectus.

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

Principal risks

Risk is inherent in all investing. The value of your investment in the fund, as well as the amount of return you receive on your investment, may fluctuate significantly. You may lose part or all of your investment in the fund or your investment may not perform as well as other similar investments. An investment in the fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or by any bank or government agency. The following is a summary description of certain risks of investing in the fund.

Market and interest rate risk. The market prices of the fund's securities may go up or down, sometimes rapidly or unpredictably, due to general market conditions, such as real or perceived adverse economic or political conditions, tariffs and trade disruptions, inflation, substantial economic downturn or recession, changes in interest rates, lack of liquidity in the bond markets or adverse investor sentiment. If the market prices of the fund's securities fall, the value of your investment will decline. The value of your investment will generally go down when interest rates rise. A rise in rates tends to have a greater impact on the prices of longer term or duration securities. A general rise in interest rates may cause investors to move out of fixed income securities on a large scale, which could adversely affect the price and liquidity of fixed income securities and could also result in increased redemptions from the fund. Recently, there have been inflationary price movements. As such, fixed income securities markets may experience heightened levels of interest rate volatility and liquidity risk.

The maturity of a security may be significantly longer than its duration. A security's maturity and other features may be more relevant than its duration in determining the security's sensitivity to other factors affecting the issuer or markets generally such as changes in credit quality or in the yield premium that the market may establish for certain types of securities.

Market events risk. The market values of securities or other assets will fluctuate, sometimes sharply and unpredictably, due to changes in general market conditions, overall economic trends or events, governmental actions or intervention, actions taken by the U.S. Federal Reserve or foreign central banks, market disruptions caused by trade disputes or other factors, political developments, armed conflicts, economic sanctions and countermeasures in response to sanctions, major cybersecurity events, investor sentiment, the global and domestic effects of a pandemic, and other factors that may or may not be related to the issuer of the security or other asset. Economies and financial markets throughout the world are increasingly interconnected. Economic, financial or political events, trading and tariff arrangements, public health events, terrorism, wars, natural disasters and other circumstances in one country or region could have

6			Western Asset Intermediate Maturity California Municipals Fund

profound impacts on global economies or markets. As a result, whether or not the fund invests in securities of issuers located in or with significant exposure to the countries or markets directly affected, the value and liquidity of the fund's investments may be negatively affected. Following Russia's invasion of Ukraine, Russian stocks lost all, or nearly all, of their market value. Other securities or markets could be similarly affected by past or future geopolitical or other events or conditions.

For example, the fallout from the COVID-19 pandemic and its subsequent variants, and the long-term impact on economies, markets, industries and individual issuers, are not known. Some sectors of the economy and individual issuers have experienced or may experience particularly large losses. Periods of extreme volatility in the financial markets; reduced liquidity of many instruments; and disruptions to supply chains, consumer demand and employee availability, may continue for some time.

Raising the ceiling on U.S. government debt has become increasingly politicized. Any failure to increase the total amount that the U.S. government is authorized to borrow could lead to a default on U.S. government obligations, with unpredictable consequences for economies and markets in the U.S. and elsewhere. Recently, inflation and interest rates have increased and may rise further. These circumstances 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.

LIBOR risk. 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. In 2017, the U.K. Financial Conduct Authority ("FCA") announced its intention to cease compelling banks to provide the quotations needed to sustain LIBOR after 2021. ICE Benchmark Administration, the administrator of LIBOR, ceased publication of most LIBOR settings on a representative basis at the end of 2021 and is expected to cease publication of a majority of U.S. dollar LIBOR settings on a representative basis after June 30, 2023. In addition, global regulators have announced that, with limited exceptions, no new LIBOR-based contracts should be entered into after 2021. Actions by regulators have resulted in the establishment of alternative reference rates to LIBOR in most major currencies. In March 2022, the U.S. federal government enacted legislation to establish a process for replacing LIBOR in certain existing contracts that do not already provide for the use of a clearly defined or practicable replacement benchmark rate as described in the legislation. Generally speaking, for contracts that do not contain a fallback provision as described in the legislation, a benchmark replacement recommended by the Federal Reserve Board will effectively automatically replace the USD LIBOR benchmark in the contract after June 30, 2023. The recommended benchmark replacement will be based on the Secured Overnight Financing Rate (SOFR) published by the Federal Reserve Bank of New York, including certain spread adjustments and benchmark replacement conforming changes. Various financial industry groups have been planning for the transition away from LIBOR, but there remains uncertainty regarding the impact of the transition from LIBOR on the fund's transactions and the financial markets generally. The transition away from LIBOR may lead to increased volatility and illiquidity in markets that rely on LIBOR and may adversely affect the fund's performance. The transition may also result in a reduction in the value of certain LIBOR-based investments held by the fund or reduce the effectiveness of related transactions such as hedges. Any such effects of the

Western Asset Intermediate Maturity California Municipals Fund				7

transition away from LIBOR, as well as other unforeseen effects, could result in losses for the fund. Since the usefulness of LIBOR as a benchmark could also deteriorate during the transition period, effects could occur at any time.

Credit risk. If an issuer or guarantor of a security held by the fund or a counterparty to a financial contract with the fund defaults or its credit is downgraded, or is perceived to be less creditworthy, or if the value of the assets underlying a security declines, the value of your investment will typically decline. Changes in actual or perceived creditworthiness may occur quickly. The fund could be delayed or hindered in its enforcement of rights against an issuer, guarantor or counterparty. Subordinated securities (meaning securities that rank below other securities with respect to claims on the issuer's assets) are more likely to suffer a credit loss than non-subordinated securities of the same issuer and will be disproportionately affected by a default, downgrade or perceived decline in creditworthiness.

Risks relating to investments in municipal securities. Municipal issuers may be adversely affected by rising health care costs, increasing unfunded pension liabilities, and by the phasing out of federal programs providing financial support. Unfavorable conditions and developments relating to projects financed with municipal securities can result in lower revenues to issuers of municipal securities, potentially resulting in defaults. The value of municipal securities can also be adversely affected by changes in the financial condition of one or more individual municipal issuers or insurers of municipal issuers, regulatory and political developments, tax law changes or other legislative actions, and by uncertainties and public perceptions concerning these and other factors. In the past, a number of municipal issuers defaulted on obligations, were downgraded or commenced insolvency proceedings. Financial difficulties of municipal issuers may experience a resurgence, particularly in the event of economic or market turmoil or a recession.

Risks associated with focusing on investments in California municipal securities. The fund focuses its investments in California municipal securities. The fund may be affected significantly by adverse economic, political or other events affecting California municipal issuers. Certain issuers of California municipal securities have experienced serious financial difficulties in the past and reoccurrence of these difficulties may impair the ability of certain California issuers to pay principal or interest on their obligations. Provisions of the California Constitution and State statutes that limit the taxing and spending authority of California governmental entities may impair the ability of California issuers to pay principal and/or interest on their obligations. Future California political and economic developments, constitutional amendments, legislative measures, executive orders, administrative regulations, litigation and voter initiatives could have an adverse effect on the debt obligations of California issuers. Also, the fund may be more volatile than a more geographically diverse fund.

High yield ("junk") bonds risk. High yield bonds are generally subject to greater credit risks than higher-grade bonds, including the risk of default on the payment of interest or principal. High yield bonds are considered speculative, typically have lower liquidity and are more difficult to value than higher grade bonds. High yield bonds tend to be volatile and more susceptible to adverse events, credit downgrades and negative sentiments and may be difficult to sell at a desired price, or at all, during periods of uncertainty or market turmoil.

8			Western Asset Intermediate Maturity California Municipals Fund

Derivatives risk. Using derivatives can increase fund losses and reduce opportunities for gains, such as when market prices, interest rates, or the derivatives themselves, behave in a way not anticipated by the fund's subadviser. Using derivatives also can have a leveraging effect and increase fund volatility. Certain derivatives have the potential for unlimited loss, regardless of the size of the initial investment. Derivatives may not be available at the time or price desired, may be difficult to sell, unwind or value, and the counterparty may default on its obligations to the fund. Derivatives are generally subject to the risks applicable to the assets, rates, indices or other indicators underlying the derivative. The value of a derivative may fluctuate more than the underlying assets, rates, indices or other indicators to which it relates. Use of derivatives may have different tax consequences for the fund than an investment in the underlying asset, and those differences may affect the amount, timing and character of income distributed to shareholders, including the proportion of income consisting of exempt-interest dividends. The U.S. government and foreign governments have adopted and implemented or are in the process of adopting and implementing regulations governing derivatives markets, including mandatory clearing of certain derivatives, margin and reporting requirements. The ultimate impact of the regulations remains unclear. Additional regulation of derivatives may make derivatives more costly, limit their availability or utility, otherwise adversely affect their performance or disrupt markets.

Leverage risk. The value of your investment may be more volatile if the fund borrows or uses instruments, such as derivatives, that have a leveraging effect on the fund's portfolio. Other risks described in the Prospectus also will be compounded because leverage generally magnifies the effect of a change in the value of an asset and creates a risk of loss of value on a larger pool of assets than the fund would otherwise have had. The fund may also have to sell assets at inopportune times to satisfy its obligations created by the use of leverage or derivatives. The use of leverage is considered to be a speculative investment practice and may result in the loss of a substantial amount, and possibly all, of the fund's assets. In addition, the fund's portfolio will be leveraged if it exercises its right to delay payment on a redemption, and losses will result if the value of the fund's assets declines between the time a redemption request is deemed to be received by the fund and the time the fund liquidates assets to meet redemption requests.

Tender option bond risk. Tender option bond ("TOB") transactions expose the fund to leverage and credit risk, and generally involve greater risk than direct investments in fixed rate municipal bonds, including the risk of loss of principal. The interest payments that the fund would typically receive in connection with a TOB transaction ("inverse floaters") vary inversely with short-term interest rates and will be reduced (and potentially eliminated) when short-term interest rates increase. In addition, the fund will be subject to leverage risk to the extent that the fund uses the proceeds that it receives from a TOB transaction to invest in other securities. The fund's investment in a TOB will generally underperform the market for fixed rate municipal securities when interest rates rise. The value and market for such inverse floaters can be volatile and can have limited liquidity. Investments in inverse floaters issued in TOB transactions are derivative instruments and, therefore, are also subject to the risks generally applicable to investments in derivatives.

Illiquidity risk. Some assets held by the fund may be or become impossible or difficult to sell and some assets that the fund wants to invest in may be impossible or difficult to purchase, particularly during times of market turmoil or due to adverse changes in the conditions of a

Western Asset Intermediate Maturity California Municipals Fund				9

particular issuer. These illiquid assets may also be volatile and difficult to value. Markets may become illiquid when, for instance, there are few, if any, interested buyers or sellers or when dealers are unwilling or unable to make a market for certain securities. As a general matter, dealers have been less willing to make markets for fixed income securities. Federal banking regulations may also cause certain dealers to reduce their inventories of certain securities, which may further decrease the fund's ability to buy or sell such securities. During times of market turmoil, there have been, and may be, no buyers or sellers for securities in entire asset classes. If the fund is forced to sell an illiquid asset to meet redemption requests or other cash needs, or to try to limit losses, the fund may be forced to sell at a substantial loss or may not be able to sell at all. The fund may not receive its proceeds from the sale of certain securities for an extended period (for example, several weeks or even longer).

Tax risk. The income on the fund's municipal securities could become subject to federal income and California State personal income taxes due to noncompliant conduct by issuers, unfavorable legislation or litigation or adverse interpretations by regulatory authorities. All or a portion of the fund's dividends that are exempt from regular federal income tax may nevertheless be taken into account for purposes of the federal alternative minimum tax.

Prepayment or call risk. Many issuers have a right to prepay their fixed income securities. Issuers may be more likely to prepay their securities if interest rates fall. If this happens, the fund may not benefit from the rise in the market price of the securities that normally accompanies a decline in interest rates, and will be forced to reinvest prepayment proceeds at a time when yields on securities available in the market are lower than the yield on prepaid securities. The fund may also lose any premium it paid to purchase the securities.

Extension risk. When interest rates rise, repayments of fixed income securities, particularly asset- and mortgage- backed securities, may occur more slowly than anticipated, extending the effective duration of these fixed income securities at below market interest rates and causing their market prices to decline more than they would have declined due to the rise in interest rates alone. This may cause the fund's share price to be more volatile.

Non-diversification risk. The fund is classified as "non-diversified," which means it may invest a larger percentage of its assets in a smaller number of issuers than a diversified fund. To the extent the fund invests its assets in a smaller number of issuers, the fund will be more susceptible to negative events affecting those issuers than a diversified fund.

Investing in ETFs risk. Unlike shares of typical mutual funds or unit investment trusts, shares of ETFs are traded on an exchange and may trade throughout a trading day. ETFs are bought and sold based on market values and not at net asset value, and therefore may trade at either a premium or discount to net asset value and may experience volatility in certain market conditions. The fund will pay brokerage commissions in connection with the purchase and sales of shares of ETFs. In addition, the fund will indirectly bear its pro rata share of fees and expenses incurred by an ETF in which it invests, including advisory fees. These expenses are in addition to management fees and other expenses that the fund bears directly in connection with its own operations. Certain ETFs are also subject to portfolio management risk. Investments in ETFs are subject to the risk that the listing exchange may halt trading of an ETF's shares, in which case the fund would be unable to sell its ETF shares unless and until trading is resumed.

10			Western Asset Intermediate Maturity California Municipals Fund

Valuation risk. The sales price the fund could receive for any particular portfolio investment may differ from the fund's valuation of the investment, particularly for securities that trade in thin or volatile markets or that are valued using a fair value methodology. These differences may increase significantly and affect fund investments more broadly during periods of market volatility. Investors who purchase or redeem fund shares on days when the fund is holding fair-valued securities may receive fewer or more shares or lower or higher redemption proceeds than they would have received if the fund had not fair-valued securities or had used a different valuation methodology. The fund's ability to value its investments may be impacted by technological issues and/or errors by pricing services or other third party service providers. The valuation of the fund's investments involves subjective judgment, which may prove to be incorrect.

Portfolio management risk. The value of your investment may decrease if the subadviser's judgment about the quality, relative yield, value or market trends affecting a particular security, industry, sector or region, or about interest rates or other market factors, is incorrect or does not produce the desired results, or if there are imperfections, errors or limitations in the models, tools and data used by the subadviser. In addition, the fund's investment strategies or policies may change from time to time. Those changes may not lead to the results intended by the subadviser and could have an adverse effect on the value or performance of the fund.

Redemption risk. The fund may experience heavy redemptions that could cause the fund to liquidate its assets at inopportune times or unfavorable prices or increase or accelerate taxable gains or transaction costs and may negatively affect the fund's net asset value, performance, or ability to satisfy redemptions in a timely manner, which could cause the value of your investment to decline.

Cybersecurity risk. Cybersecurity incidents, whether intentionally caused by third parties or otherwise, may allow an unauthorized party to gain access to fund assets, fund or customer data (including private shareholder information) or proprietary information, cause the fund, the manager, the subadviser and/or their service providers (including, but not limited to, fund accountants, custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality, or prevent fund investors from purchasing, redeeming or exchanging shares, receiving distributions or receiving timely information regarding the fund or their investment in the fund. The fund, the manager, and the subadviser have limited ability to prevent or mitigate cybersecurity incidents affecting third party service providers, and such third party service providers may have limited indemnification obligations to the fund, the manager, and/or the subadviser. Cybersecurity incidents may result in financial losses to the fund and its shareholders, and substantial costs may be incurred in order to prevent or mitigate any future cybersecurity incidents. Issuers of securities in which the fund invests are also subject to cybersecurity risks, and the value of these securities could decline if the issuers experience cybersecurity incidents.

Because technology is frequently changing, new ways to carry out cyber attacks are always developing. Therefore, there is a chance that some risks have not been identified or prepared for, or that an attack may not be detected, which puts limitations on the fund's ability to plan for or respond to a cyber attack. Like other funds and business enterprises, the fund, the manager, the subadviser and their service providers are subject to the risk of cyber incidents occurring from time to time.

The after-tax returns are shown only for Class A shares, are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. After-tax returns for classes other than Class A will vary from returns shown for Class A. Returns after taxes on distributions and sale of fund shares are higher than returns before taxes for certain periods shown because they reflect the tax benefit of capital losses realized on the redemption of fund shares.
