Investment objective

Maximize total return, consistent with prudent investment management and liquidity needs, by investing to obtain the average duration specified below.

Fees and expenses of the fund

The accompanying table describes the fees and expenses that you may pay if you buy, hold and sell shares of the fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below.

You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $100,000 in funds distributed through Franklin Distributors, LLC (“Franklin Distributors” or the “Distributor”), the fund’s distributor. More information about these and other discounts is available from your Service Agent, in the fund’s Prospectus on page 32 under the heading “Additional information about each share class,” in the appendix titled “Appendix: Waivers and Discounts Available from Certain Service Agents” on page A‑1 of the fund’s Prospectus and in the fund’s Statement of Additional Information (“SAI”) on page 88 under the heading “Sales Charge Waivers and Reductions for Class A Shares.” “Service Agents” include banks, brokers, dealers, insurance companies, investment advisers, financial consultants or advisers, mutual fund supermarkets and other financial intermediaries that have entered into an agreement with the Distributor to sell shares of the fund.

If you purchase Class I shares or Class IS shares through a Service Agent acting solely as an agent on behalf of its customers, that Service Agent may charge you a commission. Such commissions, if any, are not charged by the fund and are not reflected in the fee table or expense example below.

⁵

If the value of your account is below $1,000 ($250 for retirement plans that are not employer-sponsored), the fund may charge you a fee of $3.75 per account that is determined and assessed quarterly by the fund or your Service Agent (with an annual maximum of $15.00 per account). Please contact your Service Agent or the fund for more information.

⁶	Other expenses for Class A shares have been restated to exclude fees recaptured pursuant to the fund’s expense limitation arrangements. For the fiscal year ended December 31, 2023, amounts recaptured totaled (0.01)% for Class A shares.

⁷

The manager has agreed to waive fees and/or reimburse operating expenses (other than interest, brokerage commissions, taxes, extraordinary expenses, deferred organizational expenses and acquired fund fees and expenses), so that the ratio of total annual fund operating expenses will not exceed 0.82% for Class A shares, 1.65% for Class C shares, 1.42% for Class C1 shares, 0.85% for Class FI shares, 1.15% for Class R shares, 0.45% for Class I shares and 0.42% 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, 2025 without the Board of Directors’ 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.

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)	455	624	808	1,340
Class C (with redemption at end of period)	254	478	824	1,612
Class C (without redemption at end of period)	154	478	824	1,612
Class C1 (with redemption at end of period)	237	427	739	1,475
Class C1 (without redemption at end of period)	137	427	739	1,475
Class FI (with or without redemption at end of period)	82	256	444	990
Class R (with or without redemption at end of period)	114	356	617	1,363
Class I (with or without redemption at end of period)	46	162	289	657
Class IS (with or without redemption at end of period)	43	135	235	529

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 68% of the average value of its portfolio.

Principal investment strategies

The fund invests in a portfolio of fixed income securities of various maturities and, under normal market conditions, will invest at least 80% of its net assets, including the amount of borrowing for investment purposes, if any, in debt and fixed income securities. Although the fund may invest in debt and fixed income securities of any maturity, under normal market conditions the target dollar-weighted average effective duration for the fund is expected to range within 20% of the average duration of the domestic bond market as a whole as estimated by the fund’s subadviser. Effective duration seeks to measure the expected sensitivity of market price to changes in interest rates, taking into account the anticipated effects of structural complexities (for example, some bonds can be prepaid by the issuer).

The fund presently intends to limit its investments to U.S. dollar denominated securities and currently anticipates that it will generally only purchase debt securities that are rated in the Baa or BBB categories or above at the time of purchase by one or more Nationally Recognized Statistical Rating Organizations (“NRSROs”) or unrated securities of comparable quality at the time of purchase (as determined by the subadviser). These securities are known as “investment grade securities.” The fund may invest up to 25% of its total assets in the securities of non‑U.S. issuers. The fund may invest a substantial portion of its assets in mortgage-backed and asset-backed securities.

The fund may also enter into various exchange-traded and over‑the‑counter derivative transactions for both hedging and non‑hedging purposes, including for purposes of enhancing returns. These derivative transactions include, but are not limited to, futures, options and swaps.


Western Asset Core Bond Fund					3

In particular, the fund may use interest rate swaps, credit default swaps (including buying and selling credit default swaps on individual securities and/or baskets of securities), options (including options on credit default swaps) and futures contracts to a significant extent, although the amounts invested in these instruments may change from time to time. Other instruments may also be used to a significant extent from time to time.

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. The relative significance of the risks of investing in the fund may change over time.

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 a result, fixed income securities markets may experience heightened levels of interest rate volatility and liquidity risk. The U.S. Federal Reserve has raised interest rates from historically low levels. It may continue to raise interest rates. In addition, changes in monetary policy may exacerbate the risks associated with changing interest rates. Any additional interest rate increases in the future could cause the value of the fund’s holdings to decrease. It cannot be predicted when inflation will return to more normalized levels or how long financial authorities will counter inflationary pressures with monetary tightening.

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.

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.

Derivatives risk. Using derivatives can increase fund losses and reduce opportunities for gains, such as when market prices, interest rates, currencies, 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. The U.S. government and foreign governments have adopted and implemented 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.

Credit default swap contracts involve heightened risks and may result in losses to the fund. Credit default swaps may be illiquid and difficult to value. When the fund sells credit protection via a credit default swap, credit risk increases since the fund has exposure to both the issuer whose credit is the subject of the swap and the counterparty to the swap.

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


4				Western Asset Core Bond Fund

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.

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 particular issuer. These illiquid assets may also be volatile and difficult to value. Markets may become illiquid quickly. 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 in recent years. 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).

Foreign investments and emerging markets risk. The fund’s investments in securities of foreign issuers or issuers with significant exposure to foreign markets involve additional risk as compared to investments in U.S. securities or issuers with predominantly U.S. exposure, such as less liquid, less transparent, less regulated and more volatile markets. The value of the fund’s investments may decline because of factors affecting the particular issuer as well as foreign markets and issuers generally, such as unfavorable or unsuccessful government actions, reduction of government or central bank support, inadequate accounting standards and auditing and financial recordkeeping requirements, lack of information, political, economic, financial or social instability, terrorism, armed conflicts and other geopolitical events, and the impact of tariffs and other restrictions on trade or economic sanctions. Geopolitical or other events such as nationalization or expropriation could even cause the loss of the fund’s entire investment in one or more countries.

In addition, there may be significant obstacles to obtaining information necessary for investigations into or litigation against issuers located in or operating in certain foreign markets, particularly emerging market countries, and shareholders may have limited legal remedies.

The value of investments in securities denominated in foreign currencies increases or decreases as the rates of exchange between those currencies and the U.S. dollar change. Currency conversion costs and currency fluctuations could erase investment gains or add to investment losses. Currency exchange rates can be volatile, and are affected by factors such as general economic and political conditions, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls and speculation. The fund may be unable or may choose not to hedge its foreign currency exposure.

Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories. Settlement of trades in these markets can take longer than in other markets and the fund may not receive its proceeds from the sale of certain securities for an extended period (possibly several weeks or even longer).

The risks of foreign investments are heightened when investing in issuers in emerging market countries. 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. Their economies tend to be less diversified than those of more developed countries. They typically have fewer medical and economic resources than more developed countries, and thus they may be less able to control or mitigate the effects of a pandemic or a natural disaster. They are often particularly sensitive to market movements because their market prices tend to reflect speculative expectations. Low trading volumes may result in a lack of liquidity and in extreme price volatility.

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.

Risk of investing in fewer issuers. To the extent the fund invests its assets in a small number of issuers, or in issuers in related businesses or that are subject to related operating risks, the fund will be more susceptible to negative events affecting those issuers.

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.


Western Asset Core Bond Fund					5

Market events risk. The market values of securities or other assets will fluctuate, sometimes sharply and unpredictably, due to factors such as economic events, governmental actions or intervention, actions taken by the U.S. Federal Reserve or foreign central banks, market disruptions caused by trade disputes, labor strikes or other factors, political developments, armed conflicts, economic sanctions and countermeasures in response to sanctions, major cybersecurity events, the global and domestic effects of widespread or local health, weather or climate events, 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 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 in 2022, 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. Furthermore, events involving limited liquidity, defaults, non‑performance or other adverse developments that affect one industry, such as the financial services industry, or concerns or rumors about any events of these kinds, have in the past and may in the future lead to market-wide liquidity problems, may spread to other industries, and could negatively affect the value and liquidity of the fund’s investments.

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.

The United States and other countries are periodically involved in disputes over trade and other matters, which may result in tariffs, investment restrictions and adverse impacts on affected companies and securities. For example, the United States has imposed tariffs and other trade barriers on Chinese exports, has restricted sales of certain categories of goods to China, and has established barriers to investments in China. Trade disputes may adversely affect the economies of the United States and its trading partners, as well as companies directly or indirectly affected and financial markets generally. The United States government has prohibited U.S. persons from investing in Chinese companies designated as related to the Chinese military. These and possible future restrictions could limit the fund’s opportunities for investment and require the sale of securities at a loss or make them illiquid. Moreover, the Chinese government is involved in a longstanding dispute with Taiwan that has included threats of invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt unification of Taiwan by force, or if other geopolitical conflicts develop or get worse, economies, markets and individual securities may be severely affected both regionally and globally, and the value of the fund’s assets may go down.

Hedging risk. There can be no assurance that the fund will engage in hedging transactions at any given time, even under volatile market conditions, or that any hedging transactions the fund engages in will be successful. Hedging transactions involve costs and may reduce gains or result in losses.

Cash management and defensive investing risk. The value of the investments held by the fund for cash management or defensive investing purposes can fluctuate. Like other fixed income securities, they are subject to risk, including market, interest rate and credit risk. If the fund holds cash uninvested, the cash will be subject to the credit risk of the depository institution holding the cash and the fund will not earn income on the cash. If a significant amount of the fund’s assets is used for cash management or defensive investing purposes, the fund will be less likely to achieve its investment objective. Defensive investing may not work as intended and the value of an investment in the fund may still decline.

U.S. government securities risk. The fund may hold U.S. government securities that are not guaranteed or backed by the full faith and credit of the U.S. government, such as those issued by Fannie Mae and Freddie Mac. The maximum potential liability of the issuers of some U.S. government obligations may greatly exceed their current resources, including any legal right to support from the U.S. government. In addition, the events surrounding the U.S. federal government debt ceiling and any resulting agreement (and similar political, economic and other developments) could adversely affect the fund’s ability to achieve its investment objective. For example, a downgrade of the long-term sovereign credit rating of the U.S. could increase volatility in both stock and bond markets, result in higher interest rates and lower Treasury prices and increase the costs of all kinds of debt. These events and similar events in other areas of the world could have significant adverse effects on the economy generally and could result in significant adverse impacts on issuers of securities held by the fund and the fund itself.

In the past, the values of U.S. Government securities have been affected substantially by increased demand for them around the world. Changes in the demand for U.S. Government securities may occur at any time and may result in increased volatility in the values of those securities.

Mortgage-backed and asset-backed securities risk. When market interest rates increase, the market values of mortgage-backed securities decline. At the same time, mortgage refinancings and prepayments slow, which lengthens the effective duration of these securities. As a result, the negative effect of the interest rate increase on the market value of mortgage-backed securities is usually more pronounced than it is for other types of fixed income securities, potentially increasing the volatility of the fund. Conversely, when market interest rates decline, while the value of mortgage-backed securities may increase, the rate of prepayment of the underlying mortgages also tends to increase, which shortens the effective duration of these securities. Mortgage-backed securities are also subject to the risk that underlying borrowers will be unable to meet their obligations and the value of property that secures the mortgage may decline in value and be insufficient, upon foreclosure, to repay the associated loan. Investments in asset-backed securities are subject to similar risks. The ability of an issuer of asset-backed securities to enforce its security interest in the underlying assets may be limited, and therefore certain asset-backed securities present a heightened level of risk.


6				Western Asset Core Bond Fund

Portfolio management risk. The value of your investment may decrease if the subadvisers’ 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 subadvisers. 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 subadvisers and could have an adverse effect on the value or performance of the fund.

Portfolio turnover risk. Active and frequent trading will increase a shareholder’s tax liability and the fund’s transaction costs, which could detract from fund performance.

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. Like other funds and business enterprises, the fund, the manager, the subadvisers and their service providers are subject to the risk of cyber incidents occurring from time to time. 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 subadvisers 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 subadvisers 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 subadvisers. 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.

New ways to carry out cyber attacks continue to develop. 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.

These and other risks are discussed in more detail in the Prospectus or in the Statement of Additional Information.

More on the fund’s investment strategies, investments and risks

Important information

The fund seeks to maximize total return, consistent with prudent investment management and liquidity needs, by investing to obtain the average duration specified below.

There is no assurance that the fund will meet its investment objective.

The fund will consider an issuer to be a “non‑U.S. issuer” if the issuer is a non‑U.S. government (including any sub‑division, agency or instrumentality of a non‑U.S. government), a supranational entity or any other issuer (including corporate issuers) organized under the laws of a country outside of the United States and having a principal place of business outside of the United States. The fund will consider all other issuers to be “U.S. issuers.”

The fund invests in a portfolio of fixed income securities of various maturities and, under normal market conditions, will invest at least 80% of its net assets in debt and fixed income securities.

The fund’s 80% investment policy may be changed by the Board without shareholder approval upon 60 days’ prior notice to shareholders.

The fund’s other investment strategies and policies may be changed from time to time without shareholder approval, unless specifically stated otherwise in this Prospectus or in the SAI.

Maturity and duration

The fund may invest in securities of any maturity. The maturity of a fixed income security is a measure of the time remaining until the final payment on the security is due. Under normal market conditions the target dollar-weighted average effective duration for the fund is expected to range within 20% of the average duration of the domestic bond market as a whole as estimated by the fund’s subadviser. The dollar-weighted average effective duration of the fund may fall outside of its expected range due to market movements. If this happens, the fund’s subadviser will take action to bring the fund’s dollar-weighted average effective duration back within its expected range within a reasonable period of time.

Effective duration seeks to measure the expected sensitivity of market price to changes in interest rates, taking into account the anticipated effects of particular features of a security (for example, some bonds can be prepaid by the issuer). The assumptions that are made about a security’s features and options when calculating effective duration may prove to be incorrect. As a result, investors should be aware that effective duration is not an exact measurement and may not reliably predict a security’s price sensitivity to changes in yield or interest rates.

Generally, the longer a fund’s effective duration, the more sensitive it will be to changes in interest rates. For example, if interest rates rise by 1%, a fund with a two‑year effective duration would expect the value of its portfolio to decrease by 2% and a fund with a ten‑year effective duration would expect the value of its portfolio to decrease by 10%, all other factors being equal.

The maturity of a security may be significantly longer than its effective duration. A security’s maturity may be more relevant than its effective duration in determining the security’s sensitivity to other factors such as changes in credit quality or in the difference in yield between U.S. Treasuries and certain other types of securities.

Credit quality

The fund currently anticipates that it will generally only purchase debt securities that are rated in the Baa or BBB categories or above at the time of purchase by one or more NRSROs or unrated securities of comparable quality at the time of purchase (as determined by the subadviser). These securities are known as “investment grade securities.” The continued holding of a security downgraded below its rating at the time of purchase will be evaluated on a case by case basis. As a result, the fund may from time to time hold debt securities that are rated below investment grade in excess of the amounts described in its investment limitations. Securities rated below investment grade are commonly referred to as “junk” bonds or “high yield securities.” High yield bonds are those rated below investment grade (that is, securities rated below the Baa/BBB categories) or, if unrated, determined to be of comparable credit quality by the subadviser. If a security is rated by multiple nationally recognized statistical rating organizations (“NRSROs”) and receives different ratings, the fund will treat the security as being rated in the highest rating category received from an NRSRO. Rating categories may include sub‑categories or gradations indicating relative standing.

Derivatives

The fund may engage in a variety of transactions using derivatives, such as futures, options (including options on credit default swaps), swaps (including interest rate swaps and buying and selling credit default swaps), forwards, warrants and other synthetic instruments. Derivatives are financial instruments whose value depends upon, or is derived from, the value of something else, such as one or more underlying investments, indexes or currencies. Derivatives may be used by the fund for any of the following purposes:

•

As a hedging technique in an attempt to manage risk in the fund’s portfolio

•

As a substitute for buying or selling securities

•

As a means of changing investment characteristics of the fund’s portfolio

•

As a cash flow management technique

•

As a means of attempting to enhance returns


Western Asset Core Bond Fund					11

•

As a means of providing additional exposure to types of investments or market factors

The fund from time to time may sell protection on debt securities by entering into credit default swaps. In these transactions, the fund is generally required to pay the par (or other agreed-upon) value of a referenced debt security to the counterparty in the event of a default on or downgrade of the debt security and/or a similar credit event. In return, the fund receives from the counterparty a periodic stream of payments over the term of the contract. If no default occurs, the fund keeps the stream of payments and has no payment obligations. As the seller, the fund would effectively add leverage to its portfolio because, in addition to its net assets, the fund would be subject to loss on the par (or other agreed-upon) value it had undertaken to pay. Credit default swaps may also be structured based on an index or the debt of a basket of issuers, rather than a single issuer, and may be customized with respect to the default event that triggers purchase or other factors (for example, a particular number of defaults within a basket, or defaults by a particular combination of issuers within the basket, may trigger a payment obligation).

The fund may buy credit default swaps to hedge against the risk of default of debt securities held in its portfolio or for other reasons. As the buyer of a credit default swap, the fund would make the stream of payments described in the preceding paragraph to the seller of the credit default swap and would expect to receive from the seller a payment in the event of a default on the underlying debt security or other specified event.

Using derivatives, especially for non‑hedging purposes, may involve greater risks to the fund than investing directly in securities, particularly as these instruments may be very complex and may not behave in the manner anticipated by the fund. Certain derivative transactions may have a leveraging effect on the fund.

Use of derivatives or similar instruments 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.

Instead of, and/or in addition to, investing directly in particular securities, the fund may use derivatives and other synthetic instruments that are intended to provide economic exposure to securities, issuers or other measures of market or economic value. The fund may use one or more types of these instruments to the extent consistent with its 80% policy. The fund’s investments in derivatives and other synthetic instruments that the subadviser believes have economic characteristics similar to those securities described in the fund’s 80% investment policy will be counted towards satisfaction of that investment policy.

Registered investment companies are subject to regulatory limitations on their use of derivative investments and certain financing transactions (e.g. reverse repurchase agreements). Among other things, a fund that invests in derivative instruments beyond a specified limited amount must apply a value‑at‑risk based limit to its use of certain derivative instruments and financing transactions and must adopt and implement a derivatives risk management program. A fund that uses derivative instruments in a limited amount is not subject to the same restrictions. Regulatory restrictions may limit the fund’s ability to use derivatives as part of its investment strategy and may not work as intended to limit losses from derivatives.

The fund’s subadvisers may choose not to make use of derivatives.

Fixed income securities

Fixed income securities represent obligations of corporations, governments and other entities to repay money borrowed, usually at the maturity of the security. These securities may pay fixed, variable or floating rates of interest. However, some fixed income securities, such as zero coupon bonds, do not pay current interest but are issued at a discount from their face values. Other debt instruments, such as certain mortgage-backed and other asset-backed securities, make periodic payments of interest and/or principal. Some debt instruments are partially or fully secured by collateral supporting the payment of interest and principal. “Fixed income securities” are commonly referred to as “fixed income instruments,” “fixed income obligations,” “notes,” “loans,” “debt,” “debt obligations,” “debt instruments,” “debt securities,” “corporate debt,” “bonds” and “corporate bonds.” Fixed income securities also include certain hybrid securities, such as preferred stock. When these terms are used in this Prospectus, they are not intended to be limiting.

Variable and floating rate securities

Variable rate securities reset at specified intervals, while floating rate securities reset whenever there is a change in a specified index rate. In most cases, these reset provisions reduce the impact of changes in market interest rates on the value of the security. However, the value of these securities may decline if their interest rates do not rise as much, or as quickly, as other interest rates. Conversely, these securities will not generally increase in value if interest rates decline. The fund may also invest in inverse floating rate debt instruments (“inverse floaters”). Interest payments on inverse floaters vary inversely with changes in interest rates. Inverse floaters pay higher interest (and therefore generally increase in value) when interest rates decline, and vice versa. An inverse floater may exhibit greater price volatility than a fixed rate obligation of similar credit quality.

Stripped securities

Certain fixed income securities, called stripped securities, represent the right to receive either payments of principal (“POs”) or payments of interest (“IOs”) on underlying pools of mortgages or on government securities. The value of these types of instruments may change more drastically during periods of changing interest rates than debt securities that pay both principal and interest. Interest-only and principal-only mortgage-backed securities are especially sensitive to interest rate changes, which can affect not only their prices but can also change the prepayment assumptions about those investments and income flows the fund receives from them.


12				Western Asset Core Bond Fund

Corporate debt

Corporate debt securities are fixed income securities usually issued by businesses to finance their operations. Various types of business entities may issue these securities, including corporations, trusts, limited partnerships, limited liability companies and other types of non‑governmental legal entities. Notes, bonds, debentures and commercial paper are the most common types of corporate debt securities, with the primary difference being their maturities and secured or unsecured status. Commercial paper has the shortest term and is usually unsecured. The broad category of corporate debt securities includes debt issued by U.S. or non‑U.S. companies of all kinds, including those with small, mid and large capitalizations. Corporate debt may carry variable or floating rates of interest.

Loans

The primary risk in an investment in loans is that borrowers may be unable to meet their interest and/or principal payment obligations. Loans in which the fund invests may be made to finance highly leveraged borrowers which may make such loans especially vulnerable to adverse changes in economic or market conditions. Loans in which the fund may invest may be either collateralized or uncollateralized and senior or subordinate. Investments in uncollateralized and/or subordinate loans entail a greater risk of nonpayment than do investments in loans that hold a more senior position in the borrower’s capital structure and/or are secured with collateral. In addition, loans are generally subject to illiquidity risk. The fund may acquire an interest in loans by purchasing participations in and/or assignments of portions of loans from third parties or by investing in pools of loans, such as collateralized debt obligations as further described under “Mortgage-backed and asset-backed securities.” Transactions in loans may settle on a delayed basis. As a result, the proceeds from the sale of a loan may not be available to make additional investments or to meet the fund’s redemption obligations. Bank loans may not be considered securities and therefore, the fund may not have the protections afforded by U.S. federal securities laws with respect to such investments.

U.S. government obligations

U.S. government obligations include U.S. Treasury obligations and other obligations of, or guaranteed by, the U.S. government, its agencies or government-sponsored entities. Although the U.S. government guarantees principal and interest payments on securities issued by the U.S. government and some of its agencies, such as securities issued by the U.S. Government National Mortgage Association (“Ginnie Mae”), this guarantee does not apply to losses resulting from declines in the market value of these securities. U.S. government obligations include zero coupon securities that make payments of interest and principal only upon maturity and which therefore tend to be subject to greater volatility than interest bearing securities with comparable maturities.

Some of the U.S. government securities that the fund may hold are not guaranteed or backed by the full faith and credit of the U.S. government, such as those issued by Fannie Mae (formally known as the Federal National Mortgage Association) and Freddie Mac (formally known as the Federal Home Loan Mortgage Corporation). The maximum potential liability of the issuers of some U.S. government obligations may greatly exceed their current resources, including any legal right to support from the U.S. government.

Sovereign debt

The fund may invest in sovereign debt, including emerging market sovereign debt. Sovereign debt securities may include:

•

Fixed income securities issued or guaranteed by governments, governmental agencies or instrumentalities and their political subdivisions

•

Fixed income securities issued by government-owned, controlled or sponsored entities

•

Interests issued for the purpose of restructuring the investment characteristics of instruments issued by any of the above issuers

•

Participations in loans between governments and financial institutions

•

Fixed income securities issued by supranational entities such as the World Bank. A supranational entity is a bank, commission or company established or financially supported by the national governments of one or more countries to promote reconstruction or development

Sovereign government and supranational debt involve many of the risks of foreign and emerging markets investments as well as the risk of debt moratorium, repudiation or renegotiation and the fund may be unable to enforce its rights against the issuers.

Mortgage-backed and asset-backed securities

Mortgage-backed securities may be issued by private issuers, by U.S. government-sponsored entities such as Fannie Mae or Freddie Mac or by agencies of the U.S. government, such as Ginnie Mae. Mortgage-backed securities represent direct or indirect participations in, or are collateralized by and payable from, mortgage loans secured by real property.

Unlike mortgage-backed securities issued or guaranteed by agencies of the U.S. government or government-sponsored entities, mortgage-backed securities issued by private issuers do not have a government or government-sponsored entity guarantee (but may have other credit enhancement), and may, and frequently do, have less favorable collateral, credit risk or other underwriting characteristics.

Residential mortgage-backed securities (“RMBS”) are comprised of a pool of mortgage loans created by banks and other financial institutions. Commercial mortgage-backed securities (“CMBS”) are a type of mortgage-backed security backed by commercial mortgages rather than residential real estate.

Asset-backed securities represent participations in, or are secured by and payable from, assets such as installment sales or loan contracts, leases, credit card receivables and other categories of receivables.


Western Asset Core Bond Fund					13

Collateralized mortgage obligations (“CMOs”) are debt obligations collateralized by mortgage loans or mortgage pass-through securities. CMOs are a type of mortgage-backed security. CMOs may be collateralized by Ginnie Mae, Fannie Mae or Freddie Mac Certificates, or may be collateralized by whole loans or private pass-throughs (referred to as “Mortgage Assets”). Payments of principal and of interest on the Mortgage Assets, and any reinvestment income thereon, provide the issuer with income to pay debt service on the CMOs. In a CMO, a series of bonds or certificates is issued in multiple classes. Each class of CMOs, often referred to as a “tranche,” is issued at a specified fixed or floating coupon rate and has a stated maturity or final distribution date. Principal prepayments on the Mortgage Assets may cause the CMOs to be retired substantially earlier than their stated maturities or final distribution dates. Interest is paid or accrues on all classes of the CMOs on a monthly, quarterly or semi-annual basis. The principal of and interest on the Mortgage Assets may be allocated among the several classes of a series of a CMO in innumerable ways. As market conditions change, and particularly during periods of rapid or unanticipated changes in market interest rates, the attractiveness of the CMO classes and the ability of the structure to provide the anticipated investment characteristics may be significantly reduced. Such changes can result in volatility in the market value, and in some instances reduced liquidity, of the CMO class.

Collateralized debt obligations (“CDOs”) are a type of asset-backed security. CDOs include collateralized bond obligations (“CBOs”), collateralized loan obligations (“CLOs”) and other similarly structured securities. A CBO is a trust or other special purpose entity which is typically backed by a diversified pool of fixed income securities (which may include high risk, below investment grade securities). A CLO is a trust or other special purpose entity that is typically collateralized by a pool of loans, which may also include, among others, domestic and non‑U.S. senior secured loans, senior unsecured loans, and subordinated corporate loans, including loans that may be rated below investment grade or equivalent unrated loans. Like CMOs, CDOs generally issue separate series or “tranches” which vary with respect to risk and yield. These tranches can experience substantial losses due to actual defaults, increased sensitivity to defaults due to collateral default and disappearance of subordinate tranches, market anticipation of defaults, as well as investor aversion to CDO securities as a class. Interest on certain tranches of a CDO may be paid in kind (paid in the form of obligations of the same type rather than cash), which involves continued exposure to default risk with respect to such payments.

Municipal securities

Municipal securities include debt obligations issued by any of the 50 U.S. states and the District of Columbia or their political subdivisions, agencies and public authorities, certain other U.S. governmental issuers (such as Puerto Rico, the U.S. Virgin Islands and Guam) and other qualifying issuers, participation or other interests in these securities and other structured securities. Although municipal securities are issued by qualifying issuers, payments of principal and interest on municipal securities may be derived solely from revenues from certain facilities, mortgages or private industries, and may not be backed by the issuers themselves. These securities include participation or other interests in municipal securities issued or backed by banks, insurance companies and other financial institutions.

Municipal securities include general obligation bonds, revenue bonds, housing authority bonds, private activity bonds, industrial development bonds, residual interest bonds, tender option bonds, tax and revenue anticipation notes, bond anticipation notes, tax‑exempt commercial paper, municipal leases, participation certificates and custodial receipts. General obligation bonds are backed by the full faith and credit of the issuing entity. Revenue bonds are typically used to fund public works projects, such as toll roads, airports and transportation facilities, that are expected to produce income sufficient to make the payments on the bonds, since they are not backed by the full taxing power of the municipality. Housing authority bonds are used primarily to fund low to middle income residential projects and may be backed by the payments made on the underlying mortgages. Tax and revenue anticipation notes are generally issued in order to finance short-term cash needs or, occasionally, to finance construction. Tax and revenue anticipation notes are expected to be repaid from taxes or designated revenues in the related fiscal period, and they may or may not be general obligations of the issuing entity. Bond anticipation notes are issued with the expectation that their principal and interest will be paid out of proceeds from renewal notes or bonds and may be issued to finance such items as land acquisition, facility acquisition and/or construction and capital improvement projects.

Municipal securities include municipal lease obligations, which are undivided interests issued by a state or municipality in a lease or installment purchase contract which generally relates to equipment or facilities. In some cases, payments under municipal leases do not have to be made unless money is specifically approved for that purpose by an appropriate legislative body.

Foreign and emerging markets securities

The fund may invest its assets in securities of foreign issuers, including mortgage-backed securities and asset-backed securities issued by foreign entities. The value of the fund’s foreign securities may decline because of unfavorable government actions, political instability or the more limited availability of accurate information about foreign issuers, as well as factors affecting the particular issuers. The fund may invest in foreign securities issued by issuers located in emerging market countries. The fund considers a country to be an emerging market country, if, at the time of investment, it is represented in the J.P. Morgan Emerging Market Bond Index Global or the J.P. Morgan Corporate Emerging Market Bond Index Broad or categorized by the World Bank in its annual categorization as middle- or low‑income. To the extent the fund invests in these securities, the risks associated with investment in foreign issuers will generally be more pronounced.

Preferred stock and convertible securities

The fund may invest in preferred stock and convertible securities, including contingent convertible securities (“CoCos”). Preferred stock represents equity ownership of an issuer that generally entitles the holder to receive, in preference to the holders of common stock, dividends and a fixed share of the proceeds resulting from a liquidation of the company. Preferred stocks may pay dividends at fixed or variable rates. Convertible fixed income securities convert into shares of common stock of their issuer. Preferred stock and convertible fixed income securities share investment


14				Western Asset Core Bond Fund

characteristics of both fixed income and equity securities. However, the value of these securities tends to vary more with fluctuations in the underlying common stock and less with fluctuations in interest rates (unless the conversion price substantially exceeds the value of the common stock) and tends to exhibit greater volatility.

Equity securities

Although the fund invests principally in fixed income securities and related investments, the fund may from time to time invest in or receive equity securities and equity-like securities, which may include warrants, rights, exchange traded and over‑the‑counter common stocks, preferred stock, depositary receipts, trust certificates, limited partnership interests and shares of other investment companies, including exchange-traded funds, and real estate investment trusts. The fund may invest in or receive equity securities for which there exists no private or public market.

Equity securities represent an ownership interest in the issuing company. Holders of equity securities are not creditors of the company, and in the event of the liquidation of the company, would be entitled to their pro rata share of the company’s assets, if any, after creditors, including the holders of fixed income securities, and holders of any senior equity securities are paid. Equity securities typically fluctuate in price more than fixed income securities.

Warrants and rights permit, but do not obligate, their holders to subscribe for other securities. Warrants and rights are subject to the same market risks as stocks, but may be more volatile in price. An investment in warrants or rights may be considered speculative. In addition, the value of a warrant or right does not necessarily change with the value of the underlying securities and a warrant or right ceases to have value if it is not exercised prior to its expiration date.

Securities of other investment companies

The fund may invest in securities of other investment companies to the extent permitted under the Investment Company Act of 1940, as amended, and the rules thereunder. If the fund acquires shares of other investment companies, fund shareholders bear both their proportionate share of expenses in the fund (including management and advisory fees) and, indirectly, the expenses of the other investment companies.

Credit downgrades and other credit events

Credit rating or credit quality of a security is determined at the time of purchase. If, after purchase, the credit rating on a security is downgraded or the credit quality deteriorates, or if the duration of a security is extended, the subadvisers will decide whether the security should be held or sold. Upon the occurrence of certain triggering events or defaults on a security held by the fund, or if an obligor of such a security has difficulty meeting its obligations, the fund may obtain a new or restructured security or underlying assets. In that case, the fund may become the holder of securities or other assets that it could not purchase or might not otherwise hold (for example, because they are of lower quality or are subordinated to other obligations of the issuer) at a time when those assets may be difficult to sell or can be sold only at a loss. In addition, the fund may incur expenses in an effort to protect the fund’s interest in securities experiencing these events.

Zero coupon, pay‑in‑kind and deferred interest securities

Zero coupon, pay‑in‑kind and deferred interest securities may be used by issuers to manage cash flow and maintain liquidity. Zero coupon securities pay no interest during the life of the obligation but are issued at prices below their stated maturity value. Because zero coupon securities pay no interest until maturity, their prices may fluctuate more than other types of securities with the same maturity in the secondary market. However, zero coupon bonds are useful as a tool for managing duration.

Pay‑in‑kind securities have a stated coupon, but the interest is generally paid in the form of obligations of the same type as the underlying pay‑in‑kind securities (e.g., bonds) rather than in cash. These securities are more sensitive to the credit quality of the underlying issuer and their secondary market prices may fluctuate more than other types of securities with the same maturity.

Deferred interest securities are obligations that generally provide for a period of delay before the regular payment of interest begins and are issued at a significant discount from face value.

Certain zero coupon, pay‑in‑kind and deferred interest securities are subject to tax rules applicable to debt obligations acquired with “original issue discount.” The fund would generally have to accrue income on these securities for federal income tax purposes before it receives corresponding cash payments. Because the fund intends to make sufficient annual distributions of its taxable income, including accrued non‑cash income, in order to maintain its federal income tax status and avoid fund-level income and excise taxes, the fund might be required to liquidate portfolio securities at a disadvantageous time, or borrow cash, to make these distributions. The fund also accrues income on these securities prior to receipt for accounting purposes. To the extent it is deemed collectible, accrued income is taken into account when calculating the value of these securities and the fund’s net asset value per share, in accordance with the fund’s valuation policies.

When-issued securities, delayed delivery, to be announced and forward commitment transactions

Securities purchased in when-issued, delayed delivery, to be announced or forward commitment transactions will not be delivered or paid for immediately. Such transactions involve a risk of loss, for example, if the value of the securities declines prior to the settlement date. Therefore, these transactions may have a leveraging effect on the fund, making the value of an investment in the fund more volatile and increasing the fund’s overall


Western Asset Core Bond Fund					15

investment exposure. Typically, no income accrues on securities the fund has committed to purchase prior to the time delivery of the securities is made.

Forward roll transactions

In a forward roll transaction (also referred to as a mortgage dollar roll), the fund sells a mortgage-backed security while simultaneously agreeing to purchase a similar security from the same party (the counterparty) on a specified future date at a lower fixed price. During the roll period, the fund forgoes principal and interest paid on the securities. The fund is compensated by the difference between the current sales price and the forward price for the future purchase as well as by the interest earned on the cash proceeds of the initial sale. The fund may enter into a forward roll transaction with the intention of entering into an offsetting transaction whereby, rather than accepting delivery of the security on the specified date, the fund sells the security and agrees to repurchase a similar security at a later time.

Investments in forward roll transactions involve a risk of loss if the value of the securities that the fund is obligated to purchase declines below the purchase price prior to the repurchase date. Forward roll transactions may have a leveraging effect on the fund (see “When-issued securities, delayed delivery, to be announced and forward commitment transactions”).

Short-term investments

The fund may invest, directly or indirectly, in cash, money market instruments and short-term securities, including repurchase agreements, U.S. government securities, bank obligations and commercial paper. Bank obligations include bank notes, certificates of deposit, time deposits, banker’s acceptances and other similar obligations. A repurchase agreement is a transaction in which the fund purchases a security from a seller, subject to the obligation of the seller to repurchase that security from the fund at a higher price. The repurchase agreement thereby determines the yield during the fund’s holding period, while the seller’s obligation to repurchase is secured by the value of the underlying security held by the fund. The fund may also invest in money market funds, which may or may not be registered under the Investment Company Act of 1940, as amended, and/or affiliated with the fund’s manager or the subadvisers. The return on investment in these money market funds may be reduced by such money market funds’ operating expenses in addition to the fund’s own fees and expenses. As such, there is a layering of fees and expenses.

Borrowings and reverse repurchase agreements

The fund may enter into borrowing transactions. Borrowing may make the value of an investment in the fund more volatile and increase the fund’s overall investment exposure. The fund may be required to liquidate portfolio securities at a time when it would be disadvantageous to do so in order to make payments with respect to any borrowings. Interest on any borrowings will be a fund expense and will reduce the value of the fund’s shares.

The fund may enter into reverse repurchase agreements, which have characteristics like borrowings. In a reverse repurchase agreement, the fund sells securities to a counterparty, in return for cash, and the fund agrees to repurchase the securities at a later date and for a higher price, representing the cost to the fund for the cash received.

Restricted and illiquid securities

Restricted securities are securities subject to legal or contractual restrictions on their resale. An “illiquid security” is any security which the fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the security. Such conditions might prevent the sale of such securities at a time when the sale would otherwise be desirable. The fund will not acquire “illiquid securities” if such acquisition would cause the aggregate value of illiquid securities to exceed 15% of the fund’s net assets. The fund may determine that some restricted securities can be more readily sold, for example to qualified institutional buyers pursuant to SEC Rule 144A, and therefore may treat certain such securities as “liquid” for purposes of limitations on the amount of illiquid securities it may own. Investing in these restricted securities could have the effect of increasing the fund’s illiquidity if qualified buyers become, for a time, uninterested in buying these securities. These securities may be difficult to value, and the fund may have difficulty disposing of such securities promptly. The fund does not consider non‑U.S. securities to be restricted if they can be freely sold in the principal markets in which they are traded, even if they are not registered for sale in the United States.

Structured instruments

The fund may invest in various types of structured instruments, including securities that have demand, tender or put features, or interest rate reset features. These may include instruments issued by structured investment or special purpose vehicles or conduits, and may be asset-backed or mortgage-backed securities. Structured instruments may take the form of participation interests or receipts in underlying securities or other assets, and in some cases are backed by a financial institution serving as a liquidity provider. The interest rate or principal amount payable at maturity on a structured instrument may vary based on changes in one or more specified reference factors, such as currencies, interest rates, commodities, indices or other financial indicators. Changes in the underlying reference factors may result in disproportionate changes in amounts payable under a structured instrument. Some of these instruments may have an interest rate swap feature which substitutes a floating or variable interest rate for the fixed interest rate on an underlying asset or index. Structured instruments are a type of derivative instrument and the payment and credit qualities of these instruments derive from the assets embedded in the structure. For structured securities that have embedded leverage features, small changes in interest or prepayment rates may cause large and sudden price movements. Structured instruments are often subject to heightened illiquidity risk.

Inflation-indexed, inflation-protected and related securities

Inflation-indexed and inflation-protected securities are fixed income securities that are structured to provide protection against inflation and whose principal value or coupon (interest payment) is periodically adjusted according to the rate of inflation. If the index measuring inflation falls, the principal value or coupon of these securities will be adjusted downward. Consequently, the interest payable on these securities will be reduced. Also, if the principal value of these securities is adjusted according to the rate of inflation, the adjusted principal value repaid at maturity may be less than the original principal.

Inflation-protected securities denominated in the U.S. dollar include U.S. Treasury Inflation Protected Securities (“U.S. TIPS”), as well as other bonds issued by U.S. and non‑U.S. government agencies and instrumentalities or corporations and derivatives related to these securities. U.S. TIPS are inflation-protected securities issued by the U.S. Department of the Treasury the principal amounts of which are adjusted daily based upon changes in the rate of inflation (as currently represented by the non‑seasonally adjusted Consumer Price Index for All Urban Consumers, calculated with a three-month lag). U.S. TIPS pay interest semi-annually, equal to a fixed percentage of the inflation-adjusted principal amount. The interest rate on these bonds is fixed at issuance, but over the life of the bond, this interest may be paid on an increasing or decreasing principal amount that has been adjusted for inflation. The current market value of U.S. TIPS is not guaranteed and will fluctuate.

The value of inflation-indexed and inflation-protected securities held by the fund fluctuates in response to changes in real interest rates. In addition, if nominal interest rates increase at a faster rate than inflation, causing real interest rates to rise, it will lead to a decrease in the value of inflation-indexed or inflation-protected securities.

The fund may invest in other fixed-income securities that, in the belief of the fund’s subadvisers, will provide protection against inflation, including floating rate and other short duration securities. Floating rate securities bear interest at rates that are not fixed but vary with changes in specified market rates or indices, such as the prime rate, and at specified intervals.

Defensive investing

The fund may depart from its principal investment strategies in response to adverse market, economic, political or other conditions by taking temporary defensive positions, including by investing in any type of money market instruments and short-term debt securities or holding cash without regard to any percentage limitations. If a significant amount of the fund’s assets is used for defensive investing purposes, the fund will be less likely to achieve its investment objective. Although the subadvisers have the ability to take defensive positions, they may choose not to do so for a variety of reasons, even during volatile market conditions.

Other investments

The fund may also use other strategies and invest in other investments that are described, along with their risks, in the Statement of Additional Information (“SAI”). However, the fund might not use all of the strategies and techniques or invest in all of the types of investments described in this Prospectus or in the SAI. New types of mortgage-backed and asset-backed securities, derivative instruments, hedging instruments and other securities or instruments are developed and marketed from time to time. Consistent with its investment limitations, the fund may invest in new types of securities and instruments.

Percentage and other limitations

For purposes of the fund’s limitations expressed as a percentage of assets or net assets, the term “assets” or “net assets,” as applicable, means net assets plus the amount of any borrowings for investment purposes. The fund’s compliance with its investment limitations and requirements described in this Prospectus is usually determined at the time of investment. If such a percentage limitation is complied with at the time of an investment, any subsequent change in percentage resulting from a change in asset values or characteristics, a sale of securities or a change in credit quality will not constitute a violation of that limitation.

More on fund management

Franklin Templeton Fund Adviser, LLC (“FTFA” or the “manager”) (formerly known as Legg Mason Partners Fund Advisor, LLC) is the fund’s investment manager. FTFA, with offices at 280 Park Avenue, New York, New York 10017, also serves as the investment manager of other Franklin Templeton-sponsored funds. FTFA provides administrative and certain oversight services to the fund. As of December 31, 2023, FTFA’s total assets under management were approximately $182.93 billion.

Western Asset Management Company, LLC (“Western Asset”) and Western Asset Management Company Limited (“Western Asset London” and collectively with Western Asset, the “subadvisers”) provide the day‑to‑day portfolio management of the fund as subadvisers. Western Asset, established in 1971, has offices at 385 East Colorado Boulevard, Pasadena, California 91101 and 620 Eighth Avenue, New York, New York 10018.

Management fee

The fund pays a management fee at an annual rate that decreases as assets increase, as follows: 0.45% of the first $500 million of average daily net assets, 0.425% of the next $500 million of average daily net assets and 0.40% of average daily net assets over $1 billion.

For the fiscal year ended December 31, 2023, the fund paid FTFA an effective management fee of 0.34%, inclusive of fees recaptured pursuant to the fund’s expense limitation arrangements, of the fund’s average daily net assets for management services. The effective management fee reflects any fees waived by the manager (including any fees waived in connection with investments by the fund in affiliated investment companies for which the fund paid a management fee).

A discussion regarding the basis for the Board’s approval of the fund’s management agreement and subadvisory agreements is available in the fund’s Semi-Annual Report for the period ended June 30, 2023.

Expense limitation

The manager has agreed to waive fees and/or reimburse operating expenses (other than interest, brokerage commissions, taxes, extraordinary expenses, deferred organizational expenses and acquired fund fees and expenses) so that the ratio of total annual fund operating expenses will not exceed 0.82% for Class A shares, 1.65% for Class C shares, 1.42% for Class C1 shares, 0.85% for Class FI shares, 1.15% for Class R shares, 0.45% for Class I shares and 0.42% 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 are expected to continue until December 31, 2025, may be terminated prior to that date by agreement of the manager and the Board, and may be terminated at any time after that date by the manager. These arrangements, however, may be modified by the manager to decrease total annual fund operating expenses at any time. The manager is also 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. 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 recapture.

Additional information

The fund enters into contractual arrangements with various parties, including, among others, the fund’s manager and the subadvisers, who provide services to the fund. Shareholders are not parties to, or intended (or “third-party”) beneficiaries of, those contractual arrangements.

This Prospectus and the SAI provide information concerning the fund that you should consider in determining whether to purchase shares of the fund. The fund may make changes to this information from time to time. Neither this Prospectus nor the SAI is intended to give rise to any contract rights or other rights in any shareholder, other than rights conferred by federal or state securities laws.

Distribution

Franklin Distributors, LLC (“Franklin Distributors” or the “Distributor”), an indirect, wholly-owned broker/dealer subsidiary of Franklin Resources, serves as the fund’s sole and exclusive distributor.

The fund has adopted a shareholder services and distribution plan pursuant to Rule 12b‑1 under the Investment Company Act of 1940, as amended. Under the plan, the fund pays distribution and/or service fees based on an annualized percentage of average daily net assets of up to 0.25% for Class A shares; up to 1.00% for Class C shares; up to 0.70% for Class C1 shares; up to 0.25% for Class FI shares; and up to 0.50% for Class R shares. Payments by the fund under its plan go to the Distributor, financial intermediaries and other parties that provide services in connection with or are otherwise involved in the distribution of its shares or administration of plans or programs that use its shares as their funding medium, and to reimburse certain other expenses and payments. From time to time, the Distributor and/or financial intermediaries may agree to a reduction or waiver of these fees. These fees are an ongoing expense and, over time, will increase the cost of your investment and may cost you more than other types of sales charges. Class I shares and Class IS shares are not subject to distribution and/or service fees under the plan.

Additional payments

In addition to payments made to intermediaries under the fund’s shareholder services and distribution plan and other payments made by the fund for shareholder services and/or recordkeeping, the Distributor, the manager and/or their affiliates make payments for distribution, shareholder servicing, marketing and promotional activities and related expenses out of their profits and other available sources, including profits from their relationships with the fund. These payments are not reflected as additional expenses in the fee table contained in this Prospectus. The recipients of these


Western Asset Core Bond Fund					27

payments may include the Distributor and affiliates of the manager, as well as Service Agents through which investors may purchase shares of the fund, including your Service Agent. The total amount of these payments is substantial, may be substantial to any given recipient and may exceed the costs and expenses incurred by the recipient for any fund-related marketing or shareholder servicing activities. The payments described in this paragraph are often referred to as “revenue sharing payments.” Revenue sharing arrangements are separately negotiated between the Distributor, the manager and/or their affiliates, and the recipients of these payments.

Revenue sharing payments create an incentive for an intermediary or its employees or associated persons to recommend or sell shares of the fund to you. Contact your Service Agent for details about revenue sharing payments it receives or may receive. Additional information about revenue sharing payments is available in the SAI. Revenue sharing payments, as well as payments by the fund under the shareholder services and distribution plan or for recordkeeping and/or shareholder services, also benefit the manager, the Distributor and their affiliates to the extent the payments result in more assets being invested in the fund on which fees are being charged.

Choosing a share class

The fund offers multiple share classes. Each share class represents an investment in the same portfolio of securities, but each has different availability (for example, not all Service Agents offer all share classes), eligibility criteria, expense structures and arrangements for shareholder services or distribution, allowing you to choose the class that best meets your needs. You should read this section carefully and speak with your Service Agent (if applicable) to determine which share class is most appropriate for you. When choosing the appropriate share class, you should consider the following factors:

•

the amount you plan to invest;

•

the length of time you expect to own the shares;

•

the total costs associated with your investment, including any sales charges that you pay when you buy or sell fund shares and expenses that are paid out of fund assets over time;

•

whether you qualify for any reduction or waiver of the sales charge;

•

the availability of the share class;

•

the services that will be available to you and whether you meet any eligibility criteria; and

•

the amount of compensation that your Service Agent will receive.

For example, when choosing between Class A or Class C shares, you should be aware that, generally speaking, the larger the size of your investment and the longer your investment horizon, the more likely it will be that Class C shares will not be as advantageous as Class A shares. The annual distribution and/or service fees on Class C shares may cost you more over the longer term than the front‑end sales charge and service fees you would pay for larger purchases of Class A shares. If you are eligible to purchase Class I shares, you should be aware that Class I shares are not subject to a front‑end sales charge or distribution or service fees and generally have lower annual expenses than Class A or Class C shares.

Generally speaking, Class A shares have lower annual operating expenses than Class C/Class C1 shares but not as low as Class I/Class IS shares. Overall, Class IS shares generally have the lowest annual expenses of all share classes.

More information about the fund’s classes of shares is available through the fund’s website. You’ll find detailed information, free of charge and in a clear and prominent format, about sales charges and ways you can qualify for reduced or waived sales charges.

The fund’s shares are distributed by Franklin Distributors.

Share class features summary

The following table summarizes key features of the fund’s share classes. In addition, you should read carefully this Prospectus, including the fee table and the expense example at the front of this Prospectus before choosing your share class.

Please note that the minimum initial investment amount must be met on a per class basis. However, initial investments in Class C shares may be combined with existing investment amounts in Class C1 shares for the purposes of satisfying the initial investment minimums of Class C shares. In addition, your Service Agent may impose higher or lower investment minimums, or may impose no minimum investment requirement.

You or your Service Agent may instruct the fund to exchange shares of any class for shares of the same class of any other fund sold by the Distributor, provided that the fund shares to be acquired in the exchange are available to new investors in such other fund and that you are eligible to invest in such shares. For investors investing through retirement and benefit plans or fee‑based programs, you should contact your Service Agent that administers your plan or sponsors the fee‑based program to request an exchange. Certain retirement plan programs with exchange features in effect prior to November 20, 2006, as approved by the Distributor, remain eligible for exchange from Class C shares to Class A shares in accordance with the program terms. Please see the SAI for more details. In addition, you may exchange shares of the fund for another share class of the same fund if you meet the eligibility requirements of that particular class. Please contact your Service Agent or the fund about funds available for exchange.

^*	If this share class is not available, you may be eligible to exchange into a different share class of such fund; see “Exchanging shares — Exchangeability between funds without the same share class” below.

Share class availability

You may buy shares of the fund either directly from the fund or through a Service Agent. Please note that your Service Agent may not offer all classes of shares since each Service Agent determines which share class(es) to make available to its clients. Your Service Agent may receive


30				Western Asset Core Bond Fund

different compensation for selling one class of shares than for selling another class, which may depend on, among other things, the type of investor account and the practices adopted by your Service Agent. Each class of shares, except Class IS shares, is authorized to pay fees for recordkeeping services, account servicing, networking, or similar services to Service Agents. As a result, operating expenses of classes that incur new or additional recordkeeping fees may increase over time. Certain Service Agents may impose their own investment fees and maintain their own practices for purchasing and selling fund shares, including higher or lower investment minimums or none at all; these practices are not described in this Prospectus or the SAI and will depend on the policies, procedures and trading platforms of the Service Agent. Your Service Agent may provide shareholder services that differ from the services provided by other Service Agents. Services provided by your Service Agent may vary by class.

Plan sponsors, plan fiduciaries and other Service Agents may choose to impose qualification requirements that differ from the fund’s share class eligibility standards as stated in this Prospectus. In certain cases, this could result in the selection of a share class with higher distribution and/or service fees than otherwise would have been incurred. The fund is not responsible for, and has no control over, the decision of any plan sponsor, plan fiduciary or Service Agent to impose such differing requirements. Please consult with your plan sponsor, plan fiduciary or Service Agent for more information about available share classes.

Please contact your Service Agent about the availability of fund shares, the shareholder services it provides for each class, the compensation it receives in connection with the sale of each share class and the Service Agent’s practices and other information.

The following table provides information on the availability of each share class based on investor type, subject to the share class’ eligibility requirements. Your Service Agent can help you determine which share class is appropriate for you. The fund reserves the right to modify or waive the eligibility policies for share class availability at any time.

¹	Shares are not available for purchase through accounts where the Distributor is the broker-dealer of record (“Distributor Accounts”).

Individual investors investing through a Service Agent may be eligible to invest in Class I or Class IS shares, if such Service Agent is acting solely as an agent on behalf of its customers pursuant to an agreement with the Distributor and such investor’s shares are held in an omnibus account on the books of the fund. Please contact your Service Agent for more information.

Class I shares may be purchased directly from the fund by the following persons: (i) current employees of the manager and its affiliates; (ii) former employees of the manager and its affiliates with existing accounts; (iii) current and former board members of investment companies managed by affiliates of Franklin Resources; (iv) current and former board members of Franklin Resources; and (v) the “immediate families” of such persons. “Immediate families” are such person’s spouse (including the surviving spouse of a deceased board member), parents, grandparents, and children and grandchildren (including step-relationships). For such investors, the minimum initial investment is $1,000 and the minimum for each purchase of additional shares is $50. Current employees may purchase additional Class I shares through a systematic investment plan.

⁴	Class C1 shares are not available for purchase by new or existing investors (except for certain retirement plan programs authorized by the Distributor prior to August 1, 2012). Class C1 shares will continue to be available for dividend reinvestment and incoming exchanges.

⁵

Investors who qualify as Clients of Eligible Financial Intermediaries or who participate in Eligible Investment Programs made available through their Service Agents (such as investors in fee‑based advisory or mutual fund “wrap” programs) are eligible to purchase, directly or via exchange, Class I or Class IS shares, among other share classes. In such cases your ability to hold Class I or Class IS shares may be premised on your continuing participation in a fee‑based advisory or mutual fund wrap program. Your Service Agent may reserve the right to redeem your Class I or Class IS shares or exchange your Class I or Class IS shares or exchange them for Class A shares of the same fund, as applicable, if you terminate your fee‑based advisory or mutual fund wrap program and are no longer eligible for Class I or Class IS shares. You may be subject to an initial sales charge in connection with such exchange, and you will be subject to the annual distribution and/or service fee applicable to Class A shares. Any redemption may generate a taxable gain or loss and significantly change the asset allocation of your account.

Omnibus Retirement Plans are retirement plans held on the books of the fund in a plan level or omnibus level account and include: (i) 401(k) plans; (ii) 457 plans; (iii) employer-sponsored 403(b) plans; (iv) profit-sharing plans; (v) non‑qualified deferred compensation plans; (vi) employer-sponsored benefit plans (including health savings accounts); (vii) defined benefit plans; (viii) other similar employer-sponsored retirement and benefit plans; (ix) individual retirement accounts that are administered on the same IRA recordkeeping platform and that invest in the fund through a single omnibus account pursuant to a special contractual arrangement with the fund or the Distributor; and (x) investors who rollover fund shares from a retirement plan into an individual retirement account administered on the same retirement plan platform. SIMPLE IRAs are considered Omnibus Retirement Plans if they are employer-sponsored and held at the plan level.

Individual Retirement Plans include: (i) retirement plans investing through brokerage accounts; (ii) certain retirement plans with direct relationships to the fund that are not Institutional Investors nor investing through omnibus accounts; and (iii) individual retirement vehicles not held through an omnibus account, such as: (a) traditional and Roth IRAs; (b) Coverdell education savings accounts; (c) individual 403(b)(7) custodial accounts; (d) Keogh plans; (e) SEPs; (f) SARSEPs; and (g) SIMPLE IRAs or similar accounts. Individual Retirement Plans include plans held at the individual participant level. Individual Retirement Plans are treated like individual investors for purposes of determining sales charges and any


Western Asset Core Bond Fund					31

applicable sales charge reductions or waivers.

Clients of Eligible Financial Intermediaries include: investors who invest in the fund through Service Agents that (a) charge such investors an ongoing fee for advisory, investment, consulting or similar services, or (b) have entered into an agreement with the Distributor to offer Class A, Class C, Class FI, Class R, Class I or Class IS shares through a no‑load network or platform (including college savings vehicles) (“Eligible Investment Programs”). These investors may include (i) investors who invest in the fund through the program of a Service Agent where the investor typically invests $10 million or more in assets under management in accounts with the Service Agent (“Management Accounts”); (ii) pension and profit sharing plans; (iii) other employee benefit trusts; (iv) endowments; (v) foundations; (vi) corporations; (vii) college savings vehicles such as Section 529 plans; and (viii) direct retail investment platforms through mutual fund “supermarkets,” where the sponsor links its client’s account (including IRA accounts on such platforms) to a master account in the sponsor’s name.

Institutional Investors may include: (i) corporations; (ii) banks; (iii) trust companies; (iv) insurance companies; (v) investment companies; (vi) foundations; (vii) endowments; and (viii) other similar entities. The Distributor or the Service Agent may impose additional eligibility requirements or criteria to determine if an investor, including the types of investors listed above, qualifies as an Institutional Investor.

Additional information about each share class

Class A shares

The public offering price of Class A shares is the net asset value per share plus the applicable sales charge, unless you qualify for a sales charge waiver.

Sales charges

The following table shows the front‑end sales charge that you may pay, depending on the amount you purchase. You pay a lower rate as the size of your investment increases to certain levels called breakpoints. You do not pay a sales charge on the fund’s distributions or dividends that you reinvest in additional Class A shares.

It also shows the amount of compensation that will be paid to your Service Agent out of the sales charge if you buy shares from a Service Agent. As shown below, the sales charge may be allocated between your Service Agent and the Distributor. Service Agents will receive a distribution and/or service fee payable on Class A shares at an annual rate of up to 0.25% of the average daily net assets represented by the Class A shares serviced by them. The Distributor may not pay Service Agents selling Class A shares to Omnibus Retirement Plans a commission on the purchase price of Class A shares sold by them. However, for Omnibus Retirement Plans that are permitted to purchase shares at net asset value, the Distributor may pay Service Agents commissions of up to 1.00% of the purchase price of the Class A shares that are purchased with regular ongoing plan contributions. Please contact your Service Agent for more information.

The Distributor may pay a commission of up to 1.00% to a Service Agent for purchase amounts of $500,000 or more. In such cases, starting in the thirteenth month after purchase, the Service Agent will also receive an annual distribution and/or service fee of up to 0.25% of the average daily net assets represented by the Class A shares held by its clients. Prior to the thirteenth month, the Distributor will retain this fee. Where the Service Agent does not receive the payment of this commission, the Service Agent will instead receive the annual distribution and/or service fee starting immediately after purchase. Please contact your Service Agent for more information.

Reductions, waivers or elimination of sales charges for Class A shares

Larger purchases

You may reduce or eliminate your Class A front‑end sales charge by purchasing greater quantities. You pay a lower rate as the size of your investment increases to the breakpoint levels indicated in the chart above. You do not pay an initial sales charge when you buy $500,000 or more of Class A shares. However, if you redeem these Class A shares within 18 months of purchase, you will pay a contingent deferred sales charge of 1.00%. Please see “Contingent deferred sales charges—Class A, Class C and Class C1 shares” below.

Letter of intent and accumulation privilege

There are several ways you can combine Eligible Purchases (as defined below) within Eligible Accounts (as defined below) to take advantage of the breakpoints in the Class A sales charge schedule. In order to take advantage of reductions in sales charges that may be available to you when you purchase fund shares, you must inform your Service Agent or the fund if you believe you are eligible for a letter of intent or a right of accumulation. Whether you made Eligible Purchases through one or more Service Agents, directly from the fund or through a combination of the foregoing, it is your responsibility to inform your Service Agent or the fund if you own Eligible Purchases that you believe are eligible to be aggregated with your purchases. If you do not do so, you may not receive all sales charge reductions for which you are eligible. Account statements may be necessary in order to verify your eligibility for a reduced sales charge.

Eligible Purchases include: (i) any class of shares of any other Legg Mason or Franklin Templeton fund other than shares of such funds offered through separately managed accounts that are managed by a Franklin Templeton affiliate; and (ii) units of a Section 529 Plan managed by a Franklin Templeton affiliate. For purposes of a letter of intent and the accumulation privilege, Legg Mason and Franklin Templeton funds include BrandywineGLOBAL funds, ClearBridge Investments funds, Martin Currie funds, and Western Asset funds. They do not include the funds in the Franklin Templeton Variable Insurance Products Trust, Legg Mason Partners Variable Equity Trust, Legg Mason Partners Variable Income Trust or Legg Mason Partners Money Market Trust (except for shares held in Distributor Accounts). Please contact your Service Agent or the fund for more information.

Eligible Accounts include shares of Legg Mason and Franklin Templeton funds registered to (or held by a financial intermediary for):

•

You, individually;

•

Your “family member,” defined as your spouse or domestic partner, as recognized by applicable state law, or your children;

•

You jointly with one or more family members;

•

You jointly with one or more persons who are not family members if that other person has not included the value of the jointly-owned shares for purposes of the accumulation privilege (as described below) for that person’s separate investments in Legg Mason or Franklin Templeton fund shares;

•

A Coverdell Education Savings account for which you or a family member is the identified responsible person;

•

A trustee/custodian of an IRA (which includes a Roth IRA and an employer sponsored IRA such as a SIMPLE IRA) or your non‑ERISA covered 403(b) plan account, if the shares are registered/recorded under your or a family member’s Social Security number;

•

A 529 college savings plan over which you or a family member has investment discretion and control;

•

Any entity over which you or a family member has individual or shared authority, as principal, has investment discretion and control (for example, an UGMA/UTMA account for a child on which you or a family member is the custodian, a trust on which you or a family member is the trustee, a business account (not to include retirement plans) for your solely owned business (or the solely owned business of a family member) on which you or a family member is the authorized signer); or

•

A trust established by you or a family member as grantor.

Legg Mason and Franklin Templeton fund shares held through an administrator or trustee/custodian of an Employer Sponsored Retirement Plan (see definition below) such as a 401(k) plan do not qualify for the accumulation privilege.

Legg Mason and Franklin Templeton fund assets held in multiple Employer Sponsored Retirement Plans (as defined below) may be combined in order to qualify for sales charge breakpoints at the plan level if the plans are sponsored by the same employer.

An “Employer Sponsored Retirement Plan” is a Qualified Retirement Plan (as defined below), ERISA covered 403(b) plan or certain non‑qualified deferred compensation arrangements that operate in a similar manner to a Qualified Retirement Plan, such as 457 plans and executive deferred compensation arrangements, but not including employer sponsored IRAs. A “Qualified Retirement Plan” is an employer sponsored pension or profit sharing plan that qualifies under section 401(a) of the Internal Revenue Code, including 401(k), money purchase pension, profit sharing and defined benefit plans.

Letter of intent. You may qualify for a reduced front‑end sales charge by signing a “Letter of Intent”. A Letter of Intent allows you to combine the current or cost value, whichever is higher, of Eligible Purchases in Eligible Accounts with the value that you intend to purchase within the next 13 months, which would, if bought all at once, qualify you for a reduced sales charge. In addition, current holdings under the accumulation privilege may be included in the Letter of Intent. Shares or units redeemed or sold prior to reaching the threshold for a reduced sales charge will not be counted for these purposes. The 13‑month period begins when the Letter of Intent is received by the fund or your Service Agent and you must inform your Service Agent or the fund that later purchases are subject to a Letter of Intent. Account statements may be necessary in order to verify your eligibility. If you hold Eligible Purchases in accounts at two or more Service Agents, please contact your Service Agent to determine which shares/units may be credited toward the Letter of Intent. Certain directors, trustees and fiduciaries may be entitled to combine accounts in determining their sales charge.

During the term of the Letter of Intent, the fund will hold Class A shares representing up to 5% of the indicated amount in an escrow account for payment of the sales charge due if you do not meet the intended asset level goal during the 13‑month term of the Letter of Intent. If the full amount is not purchased during the 13‑month period, shares in the amount of any sales charge due, based on the amount of actual purchases will be redeemed from your account.


Western Asset Core Bond Fund					33

Accumulation privilege. The accumulation privilege allows you to combine the current or cost value, whichever is higher, of Eligible Purchases in Eligible Accounts with the dollar amount of your next purchase of Class A shares in determining whether you qualify for a breakpoint and a reduced front‑end sales charge. The current value of shares is determined by multiplying the number of shares as of the day prior to your current purchase by their public offering price. The cost value of shares is determined by aggregating the amount of Eligible Purchases in Eligible Accounts (including reinvested dividends and capital gains, but excluding capital appreciation), less any withdrawals, as of the date prior to your current purchase. The cost value of Eligible Purchases in Eligible Accounts, however, may only be aggregated for share purchases that took place within 18 months of your current purchase or your letter of intent start date, if applicable. You must inform your Service Agent or the fund if you are eligible for the accumulation privilege and of the other Eligible Purchases you own that are eligible to be aggregated with your purchases. Account statements may be necessary in order to verify your eligibility. If you hold Eligible Purchases in accounts at two or more Service Agents, please contact your Service Agent to determine which Eligible Purchases may be credited toward the accumulation privilege.

Waivers for certain Class A investors

Class A initial sales charges are waived for certain types of investors, including:

•

Shareholders investing in Class A shares through Distributor Accounts

•

Investors who redeemed at least the same amount of Class A shares of a fund sold by the Distributor in the past 90 days, if the investor’s Service Agent is notified

•

Directors and officers of any Franklin Templeton sponsored fund

•

Employees of Franklin Resources and its subsidiaries

•

Investors investing through certain retirement plans

•

Investors who rollover fund shares from an employer-sponsored retirement plan into an individual retirement account administered on the same retirement plan platform

•

Franklin Templeton donor-advised funds (such as the Franklin or Fiduciary Trust Charitable Programs) or investors purchasing through such funds

If you qualify for a waiver of the Class A initial sales charge, you must notify your Service Agent or the fund at 877‑6LM‑FUND/656‑3863 at the time of purchase and provide sufficient information at the time of purchase to permit verification that the purchase qualifies for the initial sales charge waiver.

Different Service Agents may impose different sales loads or offer different ways to reduce sales loads. These variations are described at the end of this Prospectus in the appendix titled “Appendix: Waivers and Discounts Available from Certain Service Agents.”

For additional information regarding waivers of Class A initial sales charges, contact your Service Agent or the fund, consult the SAI or visit www.franklintempleton.com/mutualfunds and click on the name of the fund. On the selected fund’s page, scroll to the bottom of the page and click on the disclosure labeled “Click here for funds sales charge and breakpoint information.”

Class C shares

You buy Class C shares at net asset value with no initial sales charge. However, if you redeem your Class C shares within one year of purchase, you will pay a contingent deferred sales charge of 1.00%. Omnibus Retirement Plans may not be subject to a contingent deferred sales charge.

Except as noted below, the Distributor generally will pay Service Agents selling Class C shares a commission of up to 1.00% of the purchase price of the Class C shares they sell. The Distributor will retain the contingent deferred sales charges and an annual distribution and/or service fee of up to 1.00% of the average daily net assets represented by the Class C shares serviced by these Service Agents until the thirteenth month after purchase. Starting in the thirteenth month after purchase, these Service Agents will receive an annual distribution and/or service fee of up to 1.00% of the average daily net assets represented by the Class C shares serviced by them. The Distributor may not pay Service Agents selling Class C shares to Omnibus Retirement Plans a commission on the purchase price of Class C shares sold by them. Instead, immediately after purchase, the Distributor may pay these Service Agents an annual distribution and/or service fee of up to 1.00% of the average daily net assets represented by the Class C shares serviced by them.

Class C1 shares

Class C1 shares are not available for purchase by new or existing investors (except for certain retirement plan programs authorized by the Distributor prior to August 1, 2012). Class C1 shares are available for dividend reinvestment and incoming exchanges of Class C1 shares from other funds sold by the Distributor. You buy Class C1 shares at net asset value with no initial sales charge. However, if you redeem your Class C1 shares within one year of purchase, you will pay a contingent deferred sales charge of 1.00%. However, if you exchange Class C1 shares that were not subject to a contingent deferred sales charge when initially purchased for Class C1 shares of a fund that imposes a contingent deferred sales charge, your contingent deferred sales charge will be measured from the date of your exchange.

The Distributor will retain the contingent deferred sales charges and an annual distribution and/or service fee of up to 0.70% of the average daily net assets represented by the Class C1 shares serviced by these Service Agents until the thirteenth month after purchase. Starting in the thirteenth month after purchase, these Service Agents will receive an annual distribution and/or service fee of up to 0.70% of the average daily net assets represented by the Class C1 shares serviced by them.


34				Western Asset Core Bond Fund

Class C and Class C1 share conversion

Except as noted below, Class C and Class C1 shares automatically convert to Class A shares after the shares have been held for 8 years from the purchase date; the shares will be converted in the month of, or the month following, the 8‑year anniversary of purchase. The monthly conversion processing date typically occurs around the middle of every month and generally falls on a Friday. It is the responsibility of your Service Agent and not the fund or the Distributor to ensure that you are credited with the proper holding period. If your Service Agent does not have records verifying that your shares have been held for at least 8 years, your Service Agent may not convert your Class C or Class C1 shares to Class A shares. Group retirement plans held in an omnibus recordkeeping platform through a Service Agent that does not track participant-level share lot aging may not convert Class C or Class C1 shares to Class A shares. Customers of certain Service Agents may be subject to different terms or conditions, as set by their Service Agent, in connection with such conversions. Please refer to the appendix titled “Appendix: Waivers and Discounts Available from Certain Service Agents” on page A‑1 of this Prospectus or contact your Service Agent for more information.

For Class C and Class C1 shares that have been acquired through an exchange from another fund sold by the Distributor, the purchase date is calculated from the date the shares were originally acquired in the other fund. When Class C and Class C1 shares that a shareholder acquired through a purchase or exchange convert, any other Class C and Class C1 shares that the shareholder acquired as reinvested dividends and distributions related to those shares also will convert into Class A shares on a pro rata basis.

All conversions from Class C or Class C1 shares to Class A shares will be based on the per share net asset value without the imposition of any sales load, fee or other charge. The conversion from Class C or Class C1 shares to Class A shares is not considered a taxable event for federal income tax purposes.

Contingent deferred sales charges — Class A, Class C and Class C1 shares

The contingent deferred sales charge is based on the net asset value at the time of purchase or redemption, whichever is less, and therefore you do not pay a sales charge on amounts representing appreciation or depreciation.

In addition, you do not pay a contingent deferred sales charge:

•

When you exchange shares for shares of the same share class of another fund sold by the Distributor

•

On shares representing reinvested distributions and dividends

•

On shares no longer subject to the contingent deferred sales charge

Each time you place a request to redeem shares, the fund will first redeem any shares in your account that are not subject to a contingent deferred sales charge and then redeem the shares in your account that have been held the longest.

If you redeem shares of a fund sold by the Distributor and pay a contingent deferred sales charge, you may, under certain circumstances, reinvest all or part of the redemption proceeds within 90 days in any other fund sold by the Distributor and receive pro rata credit for any contingent deferred sales charge imposed on the prior redemption. Please contact your Service Agent or the fund for additional information.

The Distributor receives contingent deferred sales charges as partial compensation for its expenses in selling shares, including the payment of compensation to your Service Agent.

Contingent deferred sales charge waivers

The contingent deferred sales charge for each share class will generally be waived:

•

On payments made through certain systematic withdrawal plans

•

On certain distributions from a retirement plan

•

For certain Omnibus Retirement Plans

•

For involuntary redemptions of small account balances

•

For 12 months following the death or disability of a shareholder

•

On redemptions with respect to investors where the Distributor did not pay the Service Agent a commission

•

On redemptions of Class A shares purchased by or through a Franklin Templeton donor-advised fund (such as the Franklin or Fiduciary Trust Charitable Programs)

To have your contingent deferred sales charge waived, you or your Service Agent must let the fund know at the time you redeem shares that you qualify for such a waiver.

Different Service Agents may offer different contingent deferred sales charge waivers. These variations are described at the end of this Prospectus in the appendix titled “Appendix: Waivers and Discounts Available from Certain Service Agents.”

For additional information regarding waivers of contingent deferred sales charges, contact your Service Agent or the fund, consult the SAI or visit the fund’s website, www.franklintempleton.com/mutualfunds, and click on the name of the fund. On the selected fund’s page, scroll to the bottom of the page and click on the disclosure labeled “Click here for funds sales charge and breakpoint information.”


Western Asset Core Bond Fund					35

Class FI shares

You buy Class FI shares at net asset value with no initial sales charge and no contingent deferred sales charge when redeemed. Service Agents receive an annual distribution and/or service fee of up to 0.25% of the average daily net assets represented by the Class FI shares serviced by them.

Class R shares

You buy Class R shares at net asset value with no initial sales charge and no contingent deferred sales charge when redeemed.

Service Agents receive an annual distribution and/or service fee of up to 0.50% of the average daily net assets represented by the Class R shares serviced by them.

Class I and Class IS shares

You buy Class I or Class IS shares at net asset value with no initial sales charge, no contingent deferred sales charge when redeemed and no asset-based fee for sales or distribution. However, if you purchase Class I or Class IS shares through a Service Agent acting solely as an agent on behalf of its customers pursuant to an agreement with the Distributor, that Service Agent may charge you a commission in an amount determined and separately disclosed to you by the Service Agent.

Because the fund is not a party to any commission arrangement between you and your Service Agent, any purchases and redemptions of Class I or Class IS shares will be made by the fund at the applicable net asset value (before imposition of the sales commission). Any commissions charged by a Service Agent are not reflected in the fees and expenses listed in the fee table or expense example in this Prospectus nor are they reflected in the performance in the bar chart and table in this Prospectus because these commissions are not charged by the fund.

Exchanging shares



Generally	You or your Service Agent may instruct the fund to exchange shares of any class for shares of the same class of any other fund sold by the Distributor, provided that the fund shares to be acquired in the exchange are available to new investors in such other fund and you are eligible to invest in such shares. Additionally, if the fund into which you wish to exchange your shares does not offer the class of shares in which you are currently invested, you may be able to exchange for a different share class (see “Exchangeability between funds without the same share class” below). In addition, you may exchange shares of a fund for a different share class of the same fund provided you meet the eligibility requirements of the share class into which you are exchanging. You may exchange shares of the fund for the same class of shares (or a different share class, if permitted) of other funds sold by the Distributor on any day that both the fund and the fund into which you are exchanging are open for business. Please contact your Service Agent or the fund about funds available for exchange. If you hold Class C1 shares, you may exchange those shares for Class C1 shares of other funds sold by the distributor, or if a fund does not offer Class C1 shares, for Class C shares. However, once you exchange Class C1 shares for Class C shares, you would not be permitted to exchange from Class C shares back to Class C1 shares. An exchange of shares of one fund for shares of another fund is considered a sale and generally results in a capital gain or loss for federal income tax purposes, unless you are investing through an IRA, 401(k) or other tax‑advantaged account. An exchange of shares of one class directly for shares of another class of the same fund normally should not be taxable for federal income tax purposes. You should talk to your tax professional before making an exchange. The exchange privilege is not intended as a vehicle for short-term trading. The fund may suspend or terminate your exchange privilege if you engage in a pattern of excessive exchanges.

Redeeming shares



Generally		You may redeem shares at their net asset value next determined after receipt by your Service Agent or the fund transfer agent of your redemption request in good order, less any applicable contingent deferred sales charge. Redemptions made through your Service Agent may be subject to transaction fees or other conditions as set by your Service Agent. If the shares are held by a fiduciary or corporation, partnership or similar entity, other documents may be required.

Redemption proceeds		Your redemption proceeds normally will be sent within 2 business days after your request is received in good order, but in any event within 7 days, regardless of the method the fund uses to make such payment (e.g., check, wire or electronic transfer (ACH)). If you make a redemption request before the fund has collected payment for the purchase of shares, the fund may delay your proceeds until payment is collected, for up to 10 days. Your redemption proceeds may be delayed, or your right to receive redemption proceeds suspended beyond 7 days, if the NYSE is closed (other than on weekends or holidays) or trading is restricted, if an emergency exists, or otherwise as permitted by order of the Securities and Exchange Commission (“SEC”). If you have a brokerage account with a Service Agent, your redemption proceeds may be sent to your Service Agent. Your redemption proceeds can be sent by check to your address of record or by wire or electronic transfer (ACH) to a bank account designated by you. To change the bank account designated to receive wire or electronic transfers, you will be required to deliver a new written authorization and may be asked to provide other documents. You may be charged a fee by your bank on a wire or an electronic transfer (ACH). In other cases, unless you direct otherwise, your proceeds will be paid by check mailed to your address of record. Under normal circumstances, the fund expects to meet redemption requests by using cash or cash equivalents in its portfolio and/or selling portfolio assets to generate cash. The fund also may pay redemption proceeds using cash obtained through borrowing arrangements that may be available from time to time. The fund may pay all or a portion of your redemption proceeds by giving you securities (for example, if the fund reasonably believes that a cash redemption may have a substantial impact on the fund and its remaining shareholders). You may pay transaction costs to dispose of the securities, and you may receive less for them than the price at which they were valued for purposes of the redemption. The fund has available an unsecured revolving credit facility (the “Global Credit Facility”) that may be used as an additional source of liquidity to fund redemptions of shares. There can be no assurance that the Global Credit Facility will remain available to the fund generally or that any available credit under the Global Credit Facility will be available to the fund when the fund seeks to draw on the Global Credit Facility. During periods of deteriorating or stressed market conditions, when an increased portion of the fund’s portfolio may be comprised of investments that have lower liquidity, or during extraordinary or emergency circumstances, the fund may be more likely to pay redemption proceeds with cash obtained through short-term borrowing arrangements (if available) or by giving you securities.

By mail		Contact your Service Agent or, if you hold shares directly with the fund, write to the fund at one of the following addresses: Regular Mail: Legg Mason Funds P.O. Box 33030 St. Petersburg, FL 33733-8030 Express, Certified or Registered Mail: Legg Mason Funds 100 Fountain Parkway St. Petersburg, FL 33716-1205

		Your written request must provide the following: • The fund name, the class of shares being redeemed and your account number • The dollar amount or number of shares being redeemed • Signature of each owner exactly as the account is registered • Medallion signature guarantees, as applicable (see “Other things to know about transactions”)

Systematic withdrawal plans		You may be permitted to schedule automatic redemptions of a portion of your shares. To qualify, you must own shares of the fund with a value of at least $5,000 and each automatic redemption must be at least $50 per transaction per month. For retirement plans subject to mandatory distribution requirements, the minimum withdrawal amounts will not apply. The following conditions apply: • Redemptions may be made monthly, quarterly, semi-annually or annually. Redemptions may be processed on the 1^st, 5^th, 10^th, 15^th, 20^th and 25^th days of the month, if no day is indicated, redemptions will be made on the 20^th day of the month. • If your shares are subject to a contingent deferred sales charge, the charge will be required to be paid upon redemption. However, the charge will be waived if your automatic redemptions do not exceed 1% monthly, 3% quarterly, 6% semiannually or 12% annually of your account’s net asset value, depending on the frequency of your plan. • Your Service Agent may impose a lower minimum amount for each automatic redemption on a monthly and quarterly basis. For more information, please contact your Service Agent or the fund or consult the SAI.


42				Western Asset Core Bond Fund

Other things to know about transactions

When you buy, exchange or redeem shares, your request must be in good order. This means you have provided the following information, without which your request may not be processed:

•

Name of the fund

•

Your account number

•

In the case of a purchase (including a purchase as part of an exchange transaction), the class of shares being bought

•

In the case of an exchange or redemption, the class of shares being exchanged or redeemed (if you own more than one class)

•

Dollar amount or number of shares being bought, exchanged or redeemed

•

In certain circumstances, the signature of each owner exactly as the account is registered (see “Redeeming shares”)

In certain circumstances, such as during periods of market volatility, severe weather and emergencies, shareholders may experience difficulties placing exchange or redemption orders by telephone. In that case, shareholders should consider using the fund’s other exchange and redemption procedures described under “Exchanging shares” and “Redeeming shares.”

The transfer agent or the fund will employ reasonable procedures to confirm that any telephone, electronic or other exchange or redemption request is genuine, which may include recording calls, asking the caller to provide certain personal identification information, employing identification numbers, sending you a written confirmation or requiring other confirmation procedures from time to time. If these procedures are followed, neither the fund nor its agents will bear any liability for these transactions, subject to applicable law.

The fund does not consider the U.S. Postal Service or private delivery services to be its agents. Therefore, deposits in the mail or with such delivery services, or receipt at the fund’s post office box, of purchase requests or redemption orders, do not constitute receipt by the fund or its transfer agent.

Purchase, redemption and exchange requests mailed to Franklin Templeton’s address in San Mateo, California, rather than to the address set forth in the “Buying shares” and “Redeeming shares” sections above, will be date- and time-stamped when received in San Mateo. If these requests are in good order, such orders will be priced at the next net asset value calculated after the date and time indicated by the stamp on the request.

The fund has the right to:

•

Suspend the offering of shares permanently or for a period of time

•

Waive or change minimum initial and additional investment amounts

•

Reject any purchase or exchange order

•

Change, revoke or suspend the exchange privilege

•

Suspend telephone transactions

•

Suspend or postpone redemptions of shares on any day when trading on the NYSE is restricted or as otherwise permitted by the SEC

•

Redeem shares if information provided in the application should prove to be incorrect in any manner judged by the fund to be material (e.g., in a manner such as to render the shareholder ineligible to purchase shares of that class)

•

Delay sending out redemption proceeds for up to seven days if, in the judgment of the subadviser, the fund could be adversely affected by immediate payment. The fund may delay redemptions beyond seven days, or suspend redemptions, only as permitted by the SEC or the Investment Company Act of 1940, as amended

The fund may be required to close your account after a period of inactivity, as determined by applicable U.S. state or territory abandoned or unclaimed property laws and regulations, and transfer your shares to the appropriate U.S. state or territory. If your shares are transferred to an applicable U.S. state or territory from an IRA account, that could be treated as a taxable distribution from your IRA to you. For more information on unclaimed property and how to maintain an active account, please contact your Service Agent or the fund’s transfer agent.

For your protection, the fund or your Service Agent may request additional information in connection with large redemptions, unusual activity in your account, or otherwise to ensure your redemption request is in good order. Please contact your Service Agent or the fund for more information.

Medallion signature guarantees

To be in good order, you may be asked to include a Medallion signature guarantee with your redemption request if you:

•

are redeeming shares and sending the proceeds to an address or bank account not currently on file or to an account in another fund sold by the Distributor with a different account registration

•

are redeeming more than $250,000 worth of shares

•

changed your account registration or your address within 15 calendar days

•

want the check paid to someone other than the account owner(s)

•

are transferring the redemption proceeds to an account with a different registration

For other types of transactions involving changes to your account registration information, please contact the fund or your Service Agent.


Western Asset Core Bond Fund					43

When a Medallion signature guarantee is called for, the shareholder should have a Medallion signature guarantee stamped under his or her signature. You can obtain a signature guarantee from most banks, dealers, brokers, credit unions and federal savings and loan institutions, national securities exchanges, registered securities associations and clearing agencies (each an “Eligible Guarantor Institution”), but not from a notary public.

The fund and its agents reserve the right to reject any Medallion signature guarantee pursuant to written signature guarantee standards or procedures, which may be revised in the future to permit them to reject Medallion signature guarantees from Eligible Guarantor Institutions. The fund may change the signature guarantee requirements from time to time without prior notice to shareholders.

Restrictions on the availability of the fund outside the United States

The distribution of this Prospectus and the offering of shares of the fund are restricted in certain jurisdictions. This Prospectus is not an offer or solicitation in any jurisdiction where such offer or solicitation is unlawful, where the person making an offer or solicitation is not authorized to make it or a person receiving an offer or solicitation may not lawfully receive it or may not lawfully invest in the fund. Investors should inform themselves as to the legal requirements within their own country before investing in the fund.

This Prospectus, and the offer of shares hereunder, are not directed at persons outside the United States. In particular, the fund is not intended to be marketed to prospective investors in any member state of the European Union, Iceland, Liechtenstein or Norway (collectively, the “European Economic Area” or “EEA”). No notification or application has been made to the competent authority of any member state of the EEA under the Alternative Investment Fund Managers Directive (or any applicable legislation or regulations made thereunder) to market the fund to investors in the EEA and it is not intended that any such notification or application shall be made.

U.S. citizens with addresses in the United States, and non‑U.S. citizens who reside in the United States and have U.S. addresses, are permitted to establish accounts with the fund. For these purposes, the “United States” and “U.S.” include U.S. territories.

The fund generally does not permit persons who do not reside in the United States or who do not have U.S. addresses to establish accounts. Therefore, U.S. citizens residing in foreign countries, as well as non‑U.S. citizens residing in foreign countries, generally will not be permitted to establish accounts with the fund.

For further information, you or your Service Agent may contact the fund at 877‑6LM‑FUND/656‑3863.

Anti-money laundering

Federal anti-money laundering regulations require all financial institutions to obtain, verify and record information that identifies each person who opens an account. When you sign your account application, you may be asked to provide additional information in order for the fund to verify your identity in accordance with these regulations. If you are opening the account in the name of a legal entity (e.g. partnership, limited liability company, business trust, corporation, etc.), you may also be required to supply the identity of the beneficial owners and a control individual with management authority, prior to the opening of your account. Accounts may be restricted and/or closed, and the monies withheld, pending verification of this information or as otherwise required under these and other federal regulations.

Small account fees/Mandatory redemptions

Small accounts may be subject to a small account fee or to mandatory redemption, as described below. Please contact your Service Agent or the fund for information on the policy applicable to your account.

Small account fees

To offset the relatively higher impact on fund expenses of servicing smaller accounts, the fund may charge you a fee of $3.75 per account that is determined and assessed quarterly by your Service Agent or by the Distributor for Distributor Accounts on the next‑to‑last business day of the quarter (with an annual maximum of $15.00 per account) if the value of your account is below $1,000 (if applicable, $250 for retirement plans that are not employer-sponsored) for any reason (including declines in net asset value). The small account fee will be charged by redeeming shares in your account. If the value of your account is $3.75 or less, the amount in the account may be exhausted to pay the small account fee. If your Service Agent or the Distributor assesses a small account fee, the small account fee will not be assessed on systematic investment plans until the end of the first quarter after the account has been established for 21 months. Payment of the small account fee through a redemption of fund shares may result in tax consequences to you (see “Taxes” for more information).

The small account fee will not be charged on, if applicable: (i) retirement plans (but will be charged on other plans that are not employer-sponsored such as traditional and Roth individual retirement accounts, Coverdell education savings accounts, individual 403(b)(7) custodial accounts, Keogh plans, SEPs, SARSEPs, SIMPLE IRAs or similar accounts); (ii) Franklin Templeton funds that have been closed to subsequent purchases for all classes; (iii) accounts that do not have a valid address as evidenced by mail being returned to the fund or its agents; (iv) Class FI, Class R, Class I and Class IS shares; and (v) for new accounts (except for new accounts opened by way of an exchange), a small account fee will not be charged during the calendar quarter in which you open your account.

If your share class is no longer offered, you may not be able to bring your account up to the minimum investment amount (although you may exchange into existing accounts of other funds sold by the Distributor in which you hold the same share class, to the extent otherwise permitted by those funds and subject to any applicable sales charges).

The small account fee is calculated on a fund‑by‑fund basis. If you have accounts in multiple funds, they will not be aggregated for the purpose of calculating the small account fee.

Some shareholders who hold accounts in Classes A, C and C1 of the same fund, may have those accounts aggregated for the purposes of these calculations. Please contact the fund or your Service Agent for more information.

Small account balance liquidations

The fund reserves the right to ask you to bring your account up to a minimum investment amount determined by your Service Agent if your account has been open for more than one year and the aggregate value of the fund shares in your account is less than $500. You will be notified in writing


Western Asset Core Bond Fund					45

and will have 30 days to make an additional investment to bring your account value up to the required level. If you choose not to do so within this 30‑day period, the fund may close your account and send you the redemption proceeds. You will not be charged a contingent deferred sales charge, if applicable, if your account is closed for this reason. If your share class is no longer offered, you may not be able to bring your account up to the minimum investment amount.

If your account is closed, you will not be eligible to have your account reinstated without imposition of any sales charges that may apply to your new purchase. Please contact your Service Agent for more information. Any redemption of fund shares may result in tax consequences to you (see “Taxes” for more information).

This policy does not apply to: (i) certain broker-controlled accounts established through the National Securities Clearing Corporation’s Networking system; (ii) Class A accounts established pursuant to a conversion from Class C or C1, and any remaining Class C or C1 accounts involved in the conversion with a low balance due to the conversion; (iii) tax-advantaged retirement plan accounts; (iv) accounts with an active systematic investment plan; (v) accounts held through a 529 college saving program; (vi) accounts that do not have a valid address as evidenced by mail being returned to the fund or its agents, (vii) Coverdell Education Saving Plan accounts; and (viii) accounts identified to us by the applicable Service Agent as being fee‑based accounts.

General

The fund may, with prior notice, change the minimum size of accounts subject to mandatory redemption, which may vary by class, implement fees for other small accounts or change the amount of the fee for small direct accounts.

Subject to applicable law, the fund may, with prior notice, adopt other policies from time to time requiring mandatory redemption of shares in certain circumstances.

For more information, please contact your Service Agent or the fund or consult the SAI.

Frequent trading of fund shares

The Board has adopted the following policies and procedures with respect to frequent trading in fund shares (“Frequent Trading Policy”).

The fund does not intend to accommodate short-term or frequent purchases and redemptions of fund shares that may be detrimental to the fund. For example, this type of trading activity could interfere with the efficient management of the fund’s portfolio or materially increase the fund’s transaction costs, administrative costs or taxes.

In addition, since the fund may invest in foreign securities, it may be vulnerable to a form of short-term trading that is sometimes referred to as “time-zone arbitrage.” Time-zone arbitrage occurs when an investor seeks to take advantage of delays between changes in the value of a mutual fund’s portfolio holdings and the reflection of those changes in the fund’s net asset value per share. These delays are more likely to occur in the case of foreign investments, due to differences between the times during which the fund’s international portfolio securities trade on foreign markets and the time as of which the fund’s net asset value is calculated (generally as of the close of the NYSE). Time-zone arbitrage traders seek to purchase or redeem shares of a fund based on events occurring after foreign market closing prices are established, but before calculation of the fund’s net asset value. This can result in the value of the fund’s shares being diluted. One of the objectives of the fund’s fair value pricing procedures is to minimize the possibility of this type of arbitrage; however, there can be no assurance that the fund’s valuation procedures will be successful in eliminating it.

Since the fund may invest in securities that are, or may be, restricted, unlisted, traded infrequently, thinly traded, or relatively illiquid (“relatively illiquid securities”), it may be particularly vulnerable to arbitrage short-term trading. Such arbitrage traders may seek to take advantage of a possible differential between the last available market prices for one or more of those relatively illiquid securities that are used to calculate the fund’s net asset value and the latest indications of market values for those securities. One of the objectives of the fund’s fair value pricing procedures is to minimize the possibilities of this type of arbitrage; however, there can be no assurance that the fund’s valuation procedures will be successful in eliminating it.

Through its transfer agent, the fund performs ongoing monitoring of shareholder trading in shares of the fund and other Franklin Templeton affiliated funds in order to try and identify shareholder trading patterns that suggest an ongoing short-term trading strategy. If shareholder trading patterns identified by the transfer agent through monitoring or from other information regarding the shareholder’s trading activity in non‑Franklin Templeton affiliated funds leads the transfer agent to reasonably conclude that such trading may be detrimental to the fund as described in this Frequent Trading Policy, the transfer agent, on behalf of the fund, may temporarily or permanently bar future purchases into the fund or, alternatively, may limit the amount, number or frequency of any future purchases and/or the method by which you may request future purchases and redemptions (including purchases and/or redemptions by an exchange or transfer between the fund and any other mutual fund).

In considering an investor’s trading patterns, the fund may consider, among other factors, the investor’s trading history both directly and, if known, through financial intermediaries, in the fund, in other Franklin Templeton affiliated funds, in non‑Franklin Templeton affiliated mutual funds, or in accounts under common control or ownership. The transfer agent may also reject any purchase request, whether or not it represents part of any ongoing trading pattern, if the manager or the fund’s transfer agent reasonably concludes that the amount of the requested transaction may disrupt or otherwise interfere with the efficient management of the fund’s portfolio. In determining what actions should be taken, the fund’s transfer agent may consider a variety of factors, including the potential impact of such remedial actions on the fund and its shareholders. If the fund is a “fund of


46				Western Asset Core Bond Fund

funds,” the fund’s transfer agent may consider the impact of the trading activity and of any proposed remedial action on both the fund and the affiliated underlying funds in which the fund invests.

Frequent trading through financial intermediaries. You are an investor subject to this Frequent Trading Policy whether you are a direct shareholder of the fund or you are investing indirectly in the fund through a financial intermediary, such as a broker-dealer, bank, trust company, insurance company product such as an annuity contract, investment advisor, or an administrator or trustee of an IRS‑recognized tax-advantaged savings plan such as a 401(k) retirement plan and a 529 college savings plan.

Some financial intermediaries maintain master accounts with the fund on behalf of their customers (“omnibus accounts”). The fund has entered into “information sharing agreements” with these financial intermediaries, which permit the fund to obtain, upon request, information about the trading activity of the intermediary’s customers that invest in the fund. If the fund’s transfer agent identifies omnibus account level trading patterns that have the potential to be detrimental to the fund, the transfer agent may, in its sole discretion, request from the financial intermediary information concerning the trading activity of its customers. Based upon its review of the information, if the transfer agent determines that the trading activity of any customer may be detrimental to the fund, it may, in its sole discretion, request the financial intermediary to restrict or limit further trading in the fund by that customer. There can be no assurance that the transfer agent’s monitoring of omnibus account level trading patterns will enable it to identify all short-term trading by a financial intermediary’s customers.

Record ownership

If you hold shares through a Service Agent, your Service Agent may establish and maintain your account and be the shareholder of record. In the event that the fund holds a shareholder meeting, your Service Agent, as record holder, will be entitled to vote your shares and may seek voting instructions from you. If you do not give your Service Agent voting instructions, your Service Agent, under certain circumstances, may nonetheless be entitled to vote your shares.

Confirmations and account statements

If you bought shares directly from the fund, you will receive a confirmation from the fund after each transaction (except a reinvestment of dividends or capital gain distributions, an investment made through the Systematic Investment Plan, exchanges made through a systematic exchange plan and withdrawals made through the Systematic Withdrawal Plan). Shareholders will receive periodic account statements.

To assist you in the management of your account you may direct the transfer agent to send copies of your confirmations and/or periodic statements to another party whom you designate, at no charge.


Western Asset Core Bond Fund					47

Dividends, other distributions and taxes

Dividends and other distributions

The fund declares dividends from any net investment income daily and pays them monthly. Shares will generally begin to earn dividends on the settlement date of purchase. The fund generally distributes capital gain, if any, once a year, typically in December. The fund may pay additional distributions and dividends in order to avoid a federal tax.

You can elect to receive dividends and/or other distributions in cash.

Unless you elect to receive dividends and/or other distributions in cash, your dividends and capital gain distributions will be automatically reinvested in shares of the same class you hold, at the net asset value determined on the reinvestment date. You do not pay a sales charge on reinvested distributions or dividends.

If you hold shares directly with the fund and you elect to receive dividends and/or distributions in cash, you have the option to receive such dividends and/or distributions via a direct deposit to your bank account or by check.

If you hold Class A, Class C1 or Class C shares directly with the fund, you may instruct the fund to have your dividends and/or distributions invested in the corresponding class of shares (or if Class C1 shares are not available, Class C shares) of another fund sold by the Distributor (excluding Western Asset Government Reserves), subject to the following conditions:

•

You meet the minimum initial investment requirement of the other fund; and

•

The other fund is available for sale in your state.

To change those instructions, you must notify your Service Agent or the fund at least three days before the next distribution is to be paid.

Please contact your Service Agent or the fund to discuss what options are available to you for receiving your dividends and other distributions.

The Board reserves the right to revise the dividend policy or postpone the payment of dividends, if warranted in the Board’s judgment, due to unusual circumstances.

Taxes

The following discussion is very general, applies only to shareholders who are U.S. persons, and does not address shareholders subject to special rules, such as those who hold fund shares through an IRA, 401(k) plan or other tax‑advantaged account. Except as specifically noted, the discussion is limited to federal income tax matters, and does not address state, local, foreign or non‑income taxes. Further information regarding taxes, including certain federal income tax considerations relevant to non‑U.S. persons, is included in the SAI. Because each shareholder’s circumstances are different and special tax rules may apply, you should consult your tax professional about federal, state, local and/or foreign tax considerations that may be relevant to your particular situation.

In general, redeeming shares, exchanging shares and receiving dividends and distributions (whether received in cash or reinvested in additional shares or shares of another fund) are all taxable events. An exchange between classes of shares of the same fund normally is not taxable for federal income tax purposes, whether or not the shares are held in a taxable account.

The following table summarizes the tax status of certain transactions related to the fund.


Transaction		Federal income tax status
Redemption or exchange of shares		Usually capital gain or loss; long-term only if shares are owned more than one year
Dividends of investment income and distributions of net short-term capital gain		Ordinary income, or in certain cases qualified dividend income
Distributions of net capital gain (excess of net long-term capital gain over net short-term capital loss)		Long-term capital gain if reported as capital gain dividends by the fund

Distributions attributable to short-term capital gains are taxable to you as ordinary income. Distributions attributable to qualified dividend income received by the fund, if any, may be eligible to be taxed to noncorporate shareholders at the reduced rates applicable to long-term capital gain if certain requirements are satisfied. Distributions of net capital gain reported by the fund as capital gain dividends are taxable to you as long-term capital gain regardless of how long you have owned your shares. Noncorporate shareholders ordinarily pay tax at reduced rates on long-term capital gain.

If the fund realizes capital gains in excess of realized capital losses in any fiscal year, it generally expects to make capital gain distributions to shareholders. You may receive distributions that are attributable to appreciation of portfolio securities that happened before you made your investment but had not been realized at the time you made your investment, or that are attributable to capital gains or other income that, although realized by the fund, had not yet been distributed at the time you made your investment. Unless you purchase shares through a tax‑advantaged account, these distributions will be taxable to you even though they economically represent a return of a portion of your investment. You may want


48				Western Asset Core Bond Fund

to avoid buying shares when the fund is about to declare a dividend or capital gain distribution. You should consult your tax professional before buying shares no matter when you are investing.

A Medicare contribution tax is imposed at the rate of 3.8% on all or a portion of net investment income of U.S. individuals if their income exceeds specified thresholds and on all or a portion of undistributed net investment income of certain estates and trusts. Net investment income generally includes for this purpose dividends and capital gain distributions paid by the fund and gain on the redemption or exchange of fund shares.

A dividend declared by the fund in October, November or December and paid during January of the following year will, in certain circumstances, be treated as paid in December for tax purposes.

The fund’s investment in certain foreign securities, foreign currencies or foreign currency derivatives may affect the amount, timing, and character of fund distributions to shareholders.

After the end of each year, your Service Agent or the fund will provide you with information about the distributions and dividends you received and any redemptions of shares during the previous year. Because each shareholder’s circumstances are different and special tax rules may apply, you should consult your tax professional about your investment in the fund.


Western Asset Core Bond Fund					49

Share price

You may buy, exchange or redeem shares at their net asset value next determined after receipt of your request in good order, adjusted for any applicable sales charge. The fund’s net asset value per share is the value of its assets minus its liabilities divided by the number of shares outstanding. Net asset value is calculated separately for each class of shares.

The fund calculates its net asset value every day the NYSE is open. The fund generally values its securities and other assets and calculates its net asset value as of the scheduled close of regular trading on the NYSE, normally at 4:00 p.m. (Eastern time). If the NYSE closes at a time other than the scheduled closing time, the fund will calculate its net asset value as of the scheduled closing time. The NYSE is closed on certain holidays listed in the SAI.

In order to buy, redeem or exchange shares at a certain day’s price, you must place your order with your Service Agent or the fund transfer agent before the scheduled close of regular trading on the NYSE on that day to receive that day’s price. If the NYSE closes early on that day, you must place your order prior to the scheduled closing time. It is the responsibility of the Service Agent to transmit all orders to buy, exchange or redeem shares to the fund transfer agent on a timely basis.

Valuation of the fund’s securities and other assets is performed in accordance with the valuation policy approved by the Board. The fund’s manager serves as the fund’s valuation designee for purposes of compliance with Rule 2a‑5 under the Investment Company Act of 1940, as amended. Under the valuation policy, assets are valued as follows:

•

The valuations for fixed income 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 fair valuation techniques and methodologies.

•

Equity securities and certain derivative instruments that are traded on an exchange are valued at the closing price (which may be reported at a different time than the time at which the fund’s net asset value is calculated) or, if that price is unavailable or deemed by the manager not representative of market value, the last sale price. Where a security is traded on more than one exchange (as is often the case overseas), the security is generally valued at the price on the exchange considered by the manager to be the primary exchange. In the case of securities not traded on an exchange, or if exchange prices are not otherwise available, the prices are typically determined by independent third party pricing services that use a variety of techniques and methodologies. Investments in mutual funds are valued at the net asset value per share of the class of the underlying fund held by the fund as determined on each business day.

•

The valuations of securities traded on foreign markets and certain fixed income securities will generally be based on prices determined as of the earlier closing time of the markets in which they primarily trade. The prices of foreign equity securities typically are adjusted using a fair value model developed by an independent third party pricing service to estimate the value of those securities at the time of closing of the NYSE. 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). Foreign markets are open for trading on weekends and other days when the fund does not price its shares. Therefore, the value of the fund’s shares may change on days when you will not be able to purchase or redeem the fund’s shares.

•

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. When such prices or quotations are not available, or when the manager believes that they are unreliable, the manager will price securities in accordance with the valuation policy. Among other things, the use of a formula or other method that takes into consideration market indices, yield curves and other specific adjustments may be used to determine fair value. Fair value of a security is the amount, as determined by the manager in good faith, that the fund might reasonably expect to receive upon a current sale of the security. Fair value procedures may also be used if the manager determines that a significant event has occurred between the time at which a market price is determined and the time at which the fund’s net asset value is calculated.

Many factors may influence the price at which the fund could sell any particular portfolio investment. The sales price may well differ—higher or lower—from the fund’s last valuation, and such differences could be significant, particularly for securities that trade in relatively thin markets and/or markets that experience extreme volatility. Moreover, valuing securities using fair value methodologies involves greater reliance on judgment than valuing securities based on market quotations. Fair value methodologies may value securities higher or lower than another fund using market quotations or its own fair value methodologies to price the same securities. There can be no assurance that the fund could obtain the value assigned to a security if it were to sell the security at approximately the time at which the fund determines its net asset value. Investors who purchase or redeem fund shares on days when the fund is holding fair-valued securities may receive a greater or lesser number of shares, or higher or lower redemption proceeds, than they would have received if the fund had not fair-valued the security or had used a different methodology.

Financial highlights

The financial highlights tables are intended to help you understand the performance of each class for the past five years, unless otherwise noted. Certain information reflects financial results for a single fund share. Total return represents the rate that an investor would have earned (or lost) on an investment in the fund, assuming reinvestment of all dividends and other distributions. Unless otherwise noted, the information below has been audited by the fund’s independent registered public accounting firm, PricewaterhouseCoopers LLP, whose report, along with the fund’s financial statements, is incorporated by reference into the fund’s SAI (see back cover) and is included in the fund’s annual report. The fund’s annual report is available upon request by calling toll-free 877‑6LM‑FUND/656‑3863 or via the following hyperlink: (https://www.sec.gov/Archives/edgar/data/863520/000119312524055300/d548270dncsr.htm).

Appendix: Waivers and Discounts Available from Certain Service Agents

The availability of certain sales charge waivers and discounts will depend on whether you purchase your shares directly from the fund or through a financial intermediary. Financial intermediaries may have different policies and procedures regarding the availability of front‑end sales load waivers or contingent deferred (back‑end) sales load waivers, which are discussed below. In all instances, it is the purchaser’s responsibility to notify the fund or the purchaser’s financial intermediary at the time of purchase of any relationship or other facts qualifying the purchaser for sales charge waivers or discounts. For waivers and discounts not available through a particular financial intermediary, shareholders will have to purchase fund shares directly from the fund or through another financial intermediary to receive these waivers or discounts.

The information below has been provided by the named financial intermediaries. Please contact the applicable financial intermediary with any questions regarding how it applies the policies described below and for assistance in determining whether you may qualify for a particular sales charge waiver or discount.

MERRILL LYNCH

Purchases or sales of front‑end (i.e., Class A) or level-load (i.e., Class C) mutual fund shares through a Merrill platform or account will be eligible only for the following sales load waivers (front‑end, contingent deferred, or back‑end waivers) and discounts, which differ from those disclosed elsewhere in this fund’s Prospectus. Purchasers will have to buy mutual fund shares directly from the mutual fund company or through another intermediary to be eligible for waivers or discounts not listed below.

It is the client’s responsibility to notify Merrill at the time of purchase or sale of any relationship or other facts that qualify the transaction for a waiver or discount. A Merrill representative may ask for reasonable documentation of such facts and Merrill may condition the granting of a waiver or discount on the timely receipt of such documentation.

Additional information on waivers and discounts is available in the Merrill Sales Load Waiver and Discounts Supplement (the “Merrill SLWD Supplement”) and in the Mutual Fund Investing at Merrill pamphlet at ml.com/funds. Clients are encouraged to review these documents and speak with their financial advisor to determine whether a transaction is eligible for a waiver or discount.

EDWARD D. JONES & CO., L.P. (“EDWARD JONES”)

Policies Regarding Transactions Through Edward Jones:

Effective on or after January 1^st, 2024, the following information supersedes prior information with respect to transactions and positions held in fund shares through an Edward Jones system. Clients of Edward Jones (also referred to as “shareholders”) purchasing fund shares on the Edward Jones


Western Asset Core Bond Fund				A‑3

commission and fee‑based platforms are eligible only for the following sales charge discounts (also referred to as “breakpoints”) and waivers, which can differ from discounts and waivers described elsewhere in the mutual fund Prospectus or statement of additional information (“SAI”) or through another broker-dealer. In all instances, it is the shareholder’s responsibility to inform Edward Jones at the time of purchase of any relationship, holdings of Franklin Templeton and Legg Mason Funds (including holdings of 529 Plans where Franklin Templeton or Legg Mason serve as the primary distributor), or other facts qualifying the purchaser for discounts or waivers. Edward Jones can ask for documentation of such circumstance. Shareholders should contact Edward Jones if they have questions regarding their eligibility for these discounts and waivers.

Breakpoints

•

Breakpoint pricing, otherwise known as volume pricing, at dollar thresholds as described in the Prospectus.

Rights of Accumulation (“ROA”)

•

The applicable sales charge on a purchase of Class A shares is determined by taking into account all share classes (except certain money market funds and any assets held in group retirement plans) of the Franklin Templeton and Legg Mason Funds held by the shareholder or in an account grouped by Edward Jones with other accounts for the purpose of providing certain pricing considerations (“pricing groups”). If grouping assets as a shareholder, this includes all share classes held on the Edward Jones platform and/or held on another platform. The inclusion of eligible fund family assets in the ROA calculation is dependent on the shareholder notifying Edward Jones of such assets at the time of calculation. Money market funds are included only if such shares were sold with a sales charge at the time of purchase or acquired in exchange for shares purchased with a sales charge.

•

The employer maintaining a SEP IRA plan and/or SIMPLE IRA plan may elect to establish or change ROA for the IRA accounts associated with the plan to a plan-level grouping as opposed to including all share classes at a shareholder or pricing group level.

•

ROA is determined by calculating the higher of cost minus redemptions or market value (current shares x NAV).

Letter of Intent (“LOI”)

•

Through a LOI, shareholders can receive the sales charge and breakpoint discounts for purchases shareholders intend to make over a 13‑month period from the date Edward Jones receives the LOI. The LOI is determined by calculating the higher of cost or market value of qualifying holdings at LOI initiation in combination with the value that the shareholder intends to buy over a 13‑month period to calculate the front‑end sales charge and any breakpoint discounts. Each purchase the shareholder makes during that 13‑month period will receive the sales charge and breakpoint discount that applies to the total amount. The inclusion of eligible fund family assets in the LOI calculation is dependent on the shareholder notifying Edward Jones of such assets at the time of calculation. Purchases made before the LOI is received by Edward Jones are not adjusted under the LOI and will not reduce the sales charge previously paid. Sales charges will be adjusted if LOI is not met.

•

If the employer maintaining a SEP IRA plan and/or SIMPLE IRA plan has elected to establish or change ROA for the IRA accounts associated with the plan to a plan-level grouping, LOIs will also be at the plan-level and may only be established by the employer.

Sales Charge Waivers

Sales charges are waived for the following shareholders and in the following situations:

•

Associates of Edward Jones and its affiliates and other accounts in the same pricing group (as determined by Edward Jones under its policies and procedures) as the associate.

The redemption and repurchase occur in the same account.

^¡

The redemption proceeds are used to process an: IRA contribution, excess contributions, conversion, recharacterizing of contributions, or distribution, and the repurchase is done in an account within the same Edward Jones grouping for ROA.

•

Shares exchanged into Class A shares from another share class so long as the exchange is into the same fund and was initiated at the discretion of Edward Jones. Edward Jones is responsible for any remaining CDSC due to the fund company, if applicable. Any future purchases are subject to the applicable sales charge as disclosed in the Prospectus.

•

Exchanges from Class C shares to Class A shares of the same fund, generally, in the 84th month following the anniversary of the purchase date or earlier at the discretion of Edward Jones.

PFS INVESTMENTS INC. (“PFSI”)

Policies Regarding Fund Purchases on the PSS Platform

The following information supersedes all prior information with respect to transactions and positions held in fund shares purchased through PFSI and held on the mutual fund platform of its affiliate, Primerica Shareholder Services (“PSS”). Clients of PFSI (also referred to as “shareholders”) purchasing fund shares on the PSS platform are eligible only for the following share classes, sales charge discounts (also referred to as “breakpoints”) and waivers, which can differ from share classes, discounts and waivers described elsewhere in this Prospectus or the related statement of additional information (“SAI”) or through another broker-dealer. In all instances, it is the shareholder’s responsibility to inform PFSI at the time of a purchase of all holdings of the Franklin Templeton and Legg Mason Funds on the PSS platform, or other facts qualifying the purchaser for discounts or waivers. PFSI may request reasonable documentation of such facts and condition the granting of any discount or waiver on the timely receipt of such documents. Shareholders should contact PSS if they have questions regarding their eligibility for these discounts and waivers.

Share Classes

Shareholders purchasing fund shares on the PSS platform are eligible only for the following share classes:

•

Class A shares are available in non‑retirement accounts, individual retirement accounts (IRA), SEP IRAs, SIMPLE IRAs, Keogh Plans, and all other account types.

•

Class A1 and Class C shares are available only in accounts that already hold such shares.

Breakpoints

•

Breakpoint pricing at dollar thresholds as described in the prospectus of the fund you are purchasing.

Rights of Accumulation (“ROA”)

•

The applicable sales charge on a purchase of Class A or Class A1 shares is determined by taking into account all share classes (except any assets held in group retirement plans) of the Franklin Templeton and Legg Mason Funds held by the shareholder on the PSS platform. The inclusion of eligible fund family assets in the ROA calculation is dependent on the shareholder notifying PFSI of such assets at the time of calculation. Shares of money market funds are included only if such shares were acquired in exchange for shares of another Franklin Templeton or Legg Mason Fund purchased with a sales charge. No shares of the Franklin Templeton and Legg Mason Funds held by the shareholder away from the PSS platform, will be granted ROA with shares of any Franklin Templeton or Legg Mason Fund purchased on the PSS platform.


	A‑8					Western Asset Core Bond Fund

•

Any SEP IRA plan, any SIMPLE IRA plan or any Payroll Deduction Plan (“PDP”) on the PSS platform will be defaulted to plan-level grouping for purposes of ROA, which allows each participating employee ROA with all other eligible shares held in plan accounts on the PSS platform. At any time, a participating employee may elect to exercise a one‑time option to change grouping for purposes of ROA to shareholder- level grouping, which allows the plan account of the electing employee ROA with her other eligible holdings on the PSS platform, but not with all other eligible participant holdings in the plan. Eligible shares held in plan accounts electing shareholder-level grouping will not be available for purposes of ROA to plan accounts electing plan-level grouping.

•

ROA is determined by calculating the higher of cost minus redemptions or current market value (current shares x NAV).

Letter of Intent (“LOI”)

•

By executing a LOI, shareholders can receive the sales charge and breakpoint discounts for purchases shareholders intend to make over a 13‑month period through PFSI, from the date PSS receives the LOI. The purchase price of the LOI is determined by calculating the higher of cost or market value of qualifying holdings at LOI initiation in combination with the dollar amount the shareholder intends to invest over a 13‑month period to arrive at total investment for purposes of determining any breakpoint discount and the applicable front‑end sales charge. Each purchase the shareholder makes during that 13‑month period will receive the sales charge and breakpoint discount that applies to the projected total investment.

•

Only holdings of Franklin Templeton and Legg Mason Funds on the PSS platform are eligible for inclusion in the LOI calculation and the shareholder must notify PFSI of all eligible assets at the time of calculation.

•

Purchases made before the LOI is received by PSS are not adjusted under the LOI, and the LOI will not reduce any sales charge previously paid. Sales charges will be automatically adjusted if the total purchases required by the LOI are not met.

•

If an employer maintaining a SEP IRA plan, SIMPLE IRA or non‑IRA PDP plan on the PSS platform has elected to establish or change ROA for the IRA accounts associated with the plan to a plan-level grouping, LOIs will also be at the plan-level and may only be established by the employer. LOIs are not available to PDP IRA plans on the PSS platform with plan-level grouping for purposes of ROA, but are available to any participating employee that elects shareholder-level grouping for purposes of ROA.

Sales Charge Waivers

Sales charges are waived for the following shareholders and in the following situations:

•

Shares purchased through reinvestment of capital gains distributions and dividend reinvestment.

•

Shares purchased with the proceeds of redeemed shares of either the Franklin Templeton or Legg Mason fund families so long as the following conditions are met: 1) the proceeds are from the sale of shares within 90 days of the purchase, 2) the sale and purchase are made in the same share class and the same account or the purchase is made in an individual retirement account with proceeds from liquidations in a non‑retirement account, and 3) the redeemed shares were subject to a front‑end or deferred sales load. Automated transactions (i.e., systematic purchases and withdrawals), full or partial transfers or rollovers of retirement accounts, and purchases made after shares are automatically sold to pay account maintenance fees are not eligible for this sales charge waiver.

•

Shares exchanged into Class A or Class A1 shares from another share class so long as the exchange is into the same fund and was initiated at the discretion of PFSI. PFSI is responsible for any remaining CDSC due to the fund company, if applicable. Any future purchases are subject to the applicable sales charge as disclosed in the prospectus.

Policies Regarding Fund Purchases That Are Not Held on the PSS Platform

We will only share non‑public personal information with outside parties in the limited circumstances permitted by law.

Our employees are required to follow procedures with respect to maintaining the confidentiality of our investors’ non‑public personal information.
