Fund Summary

Investment Goal

To maximize total return consistent with prudent investment management and liquidity needs.

Fees and Expenses of the Fund

The following table describes the fees and expenses that you will incur if you buy, hold and sell shares of the Fund. You may also incur other fees, such as usual and customary brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and the Example that follows.

Annual Fund Operating Expenses

(expenses that you pay each year as a percentage of the value of your investment)

1. Other expenses are based on estimated amounts for the current fiscal year.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of the period. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

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 Fund 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.

Principal Investment Strategies

The Fund invests in a portfolio comprised of debt instruments and fixed income securities of various maturities. Under normal market conditions, the Fund will seek its investment objective by investing at least 80% of its net assets, including the amount of borrowing for investment purposes, if any, in debt and fixed income securities (Principal Investments). As part of its 80% policy, the Fund intends to invest in derivatives that (i) provide exposure to the Principal Investments, (ii) are used to risk manage the Fund’s holdings, and/or (iii) are used to enhance returns. The risk management uses of derivatives will include managing (i) investment-related risks, (ii) risks due to fluctuations in securities prices or interest rates, (iii) risks due to the credit-worthiness of an issuer, and (iv) the effective duration of the Fund’s portfolio.

The types of derivatives in which the Fund will invest include swaps and security-based swaps, futures and options on futures, swaptions and security options. The Fund may also hold U.S. Treasury securities, cash and cash equivalents. 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 sub-advisor. 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 types of fixed income securities in which the Fund may invest include corporate debt securities, U.S. and non-U.S. government securities, asset-backed securities (“ABS”), mortgage-backed securities (“MBS”) (including commercial MBS (“CMBS”), residential MBS (“RMBS”) and non-agency collateralized mortgage obligations (“CMOs”)), collateralized debt obligations (“CDOs”) and mortgage dollar rolls. The fixed income securities and debt instruments in which the Fund may invest may pay fixed, variable or floating rates of interest. The Fund will not invest more than 10% of the Fund’s total assets in CDOs. The Fund will also not invest more than 20% of its total assets in bank loans including junior loans (e.g., debt instruments that are unsecured and subordinated).

The Fund may invest up to 20% of its assets in below investment grade fixed income securities or debt instruments. For these purposes, “investment grade” is defined as investments with a rating at the time of purchase in one of the four highest categories of at least one nationally recognized statistical rating organization (“NRSRO”) (e.g., BBB- or higher or Baa3 or higher) or, if unrated, securities of comparable quality at the time of purchase (as determined by the sub-advisor). Securities rated below investment grade (e.g., BB+ to D or Baa1 to C) or, if unrated, securities of comparable quality at the time of purchase (as determined by the sub-advisor) are commonly known as “junk bonds” or “high yield securities.”

The Fund may invest in securities issued by both U.S. and non-U.S. issuers (including issuers in emerging markets) but the Fund will not invest more than 25% of its total assets in the securities or debt instruments of non-U.S. issuers. The Fund presently intends to limit its investments to U.S. dollar denominated securities.

The Fund may engage in active and frequent trading as part of its investment strategies.

The Fund may also hold equity securities of any type acquired in reorganizations of issuers of fixed income securities or debt instruments (“work out securities”), non-convertible preferred securities, warrants and exchange-traded funds (“ETFs”) that provide exposure to these investments.

The Fund is an actively managed exchange-traded fund (ETF) that does not seek to replicate the performance of a specified index.

Principal Risks

You could lose money by investing in the Fund. ETF shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value (NAV), trading price, yield, total return and ability to meet its investment goal. Unlike many ETFs, the Fund is not an index-based ETF.

Market The market values of securities or other investments owned by the Fund will go up or down, sometimes rapidly or unpredictably. The market value of a security or other investment may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all investments. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

The global outbreak of the novel strain of coronavirus, COVID-19, has resulted in market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain the spread of COVID-19 have resulted in global travel restrictions and disruptions of healthcare systems, business operations and supply chains, layoffs, volatility in consumer demand for certain products, defaults and credit ratings downgrades, and other significant economic impacts. The effects of COVID-19 have impacted global economic activity across many industries and may heighten other pre-existing political, social and economic risks, locally or globally. The full impact of the COVID-19 pandemic is unpredictable and may adversely affect the Fund’s performance.

Interest Rate When interest rates rise, debt security prices generally fall. The opposite is also generally true: debt security prices rise when interest rates fall. Interest rate changes are influenced by a number of factors, including government policy, monetary policy, inflation expectations, perceptions of risk, and supply of and demand for bonds. In general, securities with longer maturities or durations are more sensitive to interest rate changes.

Credit   An issuer of debt securities may fail to make interest payments or repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security's or government's credit rating may affect a security's value. Mortgage-backed securities that are not issued by U.S. government agencies may have a greater risk of default because neither the U.S. government nor an agency or instrumentality have guaranteed or provided credit support to them. The credit quality of most asset-backed securities depends primarily on the credit quality of the underlying assets and the amount of credit support (if any) provided to the securities. While securities issued by Ginnie Mae are backed by the full faith and credit of the U.S. government, not all securities of the various U.S. government agencies are, including those of Fannie Mae and Freddie Mac. Also, guarantees of principal and interest payments do not apply to market prices, yields or the Fund’s share price. While the U.S. government has, in the past, provided financial support to Fannie Mae and Freddie Mac, the U.S. government is not obligated by law to do so and no assurance can be given that the U.S. government will do so in the future.

Mortgage Securities and Asset-Backed Securities Mortgage securities differ from conventional debt securities because principal is paid back periodically over the life of the security rather than at maturity. The Fund may receive unscheduled payments of principal due to voluntary prepayments, refinancings or foreclosures on the underlying mortgage loans. Because of prepayments, mortgage securities may be less effective than some other types of debt securities as a means of "locking in" long-term interest rates and may have less potential for capital appreciation during periods of falling interest rates. A reduction in the anticipated rate of principal prepayments, especially during periods of rising interest rates, may increase or extend the effective maturity of mortgage securities, making them more sensitive to interest rate changes, subject to greater price volatility, and more susceptible than some other debt securities to a decline in market value when interest rates rise.

Issuers of asset-backed securities may have limited ability to enforce the security interest in the underlying assets, and credit enhancements provided to support the securities, if any, may be inadequate to protect investors in the event of default. Like mortgage securities, asset-backed securities are subject to prepayment and extension risks.

Derivative Instruments The performance of derivative instruments depends largely on the performance of an underlying instrument, such as a security, interest rate or index, and such instruments often have risks similar to their underlying instrument, in addition to other risks. Derivative instruments involve costs and can create economic leverage in the Fund's portfolio which may result in significant volatility and cause the Fund to participate in losses (as well as gains) in an amount that exceeds the Fund's initial investment. Other risks include illiquidity, mispricing or improper valuation of the derivative instrument, and imperfect correlation between the value of the derivative and the underlying instrument so that the Fund may not realize the intended benefits. When a derivative is used for hedging, the change in value of the derivative may also not correlate specifically with the security, interest rate, index or other risk being hedged. With over-the-counter derivatives, there is the risk that the other party to the transaction will fail to perform.

Income The Fund's distributions to shareholders may decline when prevailing interest rates fall, when the Fund experiences defaults on debt securities it holds or when the Fund realizes a loss upon the sale of a debt security.

Prepayment Prepayment risk occurs when a debt security can be repaid in whole or in part prior to the security's maturity and the Fund must reinvest the proceeds it receives, during periods of declining interest rates, in securities that pay a lower rate of interest. Also, if a security has been purchased at a premium, the value of the premium would be lost in the event of prepayment. Prepayments generally increase when interest rates fall.

Extension Some debt securities are subject to the risk that the debt security’s effective maturity is extended because calls or prepayments are less or slower than anticipated, particularly when interest rates rise. The market value of such security may then decline and become more interest rate sensitive.

Foreign Securities (non-U.S.)  Investing in foreign securities typically involves more risks than investing in U.S. securities, and includes risks associated with: (i) internal and external political and economic developments – e.g., the political, economic and social policies and structures of some foreign countries may be less stable and more volatile than those in the U.S. or some foreign countries may be subject to trading restrictions or economic sanctions; (ii) trading practices – e.g., government supervision and regulation of foreign securities and currency markets, trading systems and brokers may be less than in the U.S.; (iii) availability of information – e.g., foreign issuers may not be subject to the same disclosure, accounting and financial reporting standards and practices as U.S. issuers; (iv) limited markets – e.g., the securities of certain foreign issuers may be less liquid (harder to sell) and more volatile; and (v) currency exchange rate fluctuations and policies – e.g., fluctuations may negatively affect investments denominated in foreign currencies and any income received or expenses paid by the Fund in that foreign currency. The risks of foreign investments may be greater in developing or emerging market countries.

Emerging Market Countries The Fund’s investments in emerging market issuers are subject to all of the risks of foreign investing generally, and have additional heightened risks due to a lack of established legal, political, business and social frameworks to support securities markets, including: delays in settling portfolio securities transactions; currency and capital

controls; greater sensitivity to interest rate changes; pervasiveness of corruption and crime; currency exchange rate volatility; and inflation, deflation or currency devaluation.

Floating Rate Corporate Investments   Floating rate corporate loans and corporate debt securities generally have credit ratings below investment grade and may be subject to resale restrictions. They are often issued in connection with highly leveraged transactions, and may be subject to greater credit risks than other investments including the possibility of default or bankruptcy. In addition, a secondary market in corporate loans may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods, which may impair the ability to accurately value existing and prospective investments and to realize in a timely fashion the full value upon the sale of a corporate loan. A significant portion of floating rate investments may be “covenant lite” loans that may contain fewer or less restrictive constraints on the borrower or other borrower-friendly characteristics.

Impairment of Collateral The value of collateral securing a loan or other corporate debt security may decline after the Fund invests and there is a risk that the value of the collateral may not be sufficient to cover the amount owed to the Fund, or the collateral securing a loan may be found invalid, may be used to pay other outstanding obligations of the borrower under applicable law or may be difficult to sell.

High-Yield Debt Securities Issuers of lower-rated or “high-yield” debt securities (also known as “junk bonds”) are not as strong financially as those issuing higher credit quality debt securities. High-yield debt securities are generally considered predominantly speculative by the applicable rating agencies as their issuers are more likely to encounter financial difficulties because they may be more highly leveraged, or because of other considerations. In addition, high yield debt securities generally are more vulnerable to changes in the relevant economy, such as a recession or a sustained period of rising interest rates, that could affect their ability to make interest and principal payments when due. The prices of high-yield debt securities generally fluctuate more than those of higher credit quality. High-yield debt securities are generally more illiquid (harder to sell) and harder to value.

When-Issued and Delayed Delivery Transactions   Mortgage-backed securities may be issued on a when-issued or delayed delivery basis, where payment and delivery take place at a future date. Because the market price of the security may fluctuate during the time before payment and delivery, the Fund assumes the risk that the value of the security at delivery may be more or less than the purchase price.

Credit-Linked Securities   Credit-linked securities, which may be considered to be a type of structured debt investment, represent an interest in a pool of, or are otherwise collateralized by, one or more reference securities such as corporate debt obligations or credit default swaps thereon or bank loan obligations. The Fund may lose money investing in credit-linked securities if a credit event (for example, a bankruptcy or failure to pay interest or principal or a restructuring) occurs with respect to a reference security, if the underlying securities otherwise perform poorly, or if certain counterparties fail to satisfy their obligations. The market for credit-linked securities may suddenly become illiquid, making it difficult for the Fund to sell such securities promptly at an acceptable price.

Variable Rate Securities   Because changes in interest rates on variable rate securities (including floating rate securities) may lag behind changes in market rates, the value of such securities may decline during periods of rising interest rates until their interest rates reset to market rates. During periods of declining interest rates, because the interest rates on variable rate securities generally reset downward, their market value is unlikely to rise to the same extent as the value of comparable fixed rate securities.

Cash/Cash Equivalents   To the extent the Fund holds cash or cash equivalents rather than securities in which it primarily invests or uses to manage risk, the Fund may not achieve its investment objectives and may underperform.

Management The Fund is subject to management risk because it is an actively managed ETF. The Fund's sub-advisor applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.

Portfolio Turnover The sub-advisor will sell a security when it believes it is appropriate to do so, regardless of how long the Fund has held the security. The Fund's portfolio turnover rate may exceed 100% per year because of the anticipated use of certain investment strategies. The rate of portfolio turnover will not be a limiting factor for the sub-advisor in making decisions on when to buy or sell securities. High turnover will increase the Fund's transaction costs and may increase your tax liability if the transactions result in capital gains.

LIBOR Transition The Fund invests in financial instruments that may have floating or variable rate calculations for payment obligations or financing terms based on the London Interbank Offered Rate (LIBOR), which is the benchmark interest rate at which major global banks lend to one another in the international interbank market for short-term loans. In 2017, the U.K.

Financial Conduct Authority announced its intention to cease compelling banks to provide the quotations needed to sustain LIBOR after 2021. Although many LIBOR rates were phased out at the end of 2021 as originally intended, a selection of widely used USD LIBOR rates will continue to be published until June 2023 in order to assist with the transition to an alternative rate. Actions by regulators have resulted in the establishment of alternative reference rates to LIBOR in most major currencies. The ultimate impact of the discontinuation of LIBOR and the transition to an alternative rate on the Fund's portfolio and markets generally remains uncertain. There can be no guarantee that financial instruments that transition to an alternative reference rate will retain the same value or liquidity as they would otherwise have had.

Cybersecurity Cybersecurity incidents, both intentional and unintentional, 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 investment manager, the sub-advisor, authorized participants, or index providers (as applicable) and listing exchanges, 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 shares or receiving distributions. The investment manager and the sub-advisor 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 investment manager or the sub-advisor. Cybersecurity incidents may result in financial losses to the Fund and its shareholders, and substantial costs may be incurred in an effort to prevent or mitigate future cybersecurity incidents. Issuers of securities in which the Fund invests are also subject to cybersecurity risks, and the value of these securities could decline if the issuers experience cybersecurity incidents. Because technology is frequently changing, new ways to carry out cyber attacks are always developing. Therefore, there is a chance that some risks have not been identified or prepared for, or that an attack may not be detected, which puts limitations on the Fund's ability to plan for or respond to a cyber attack. Like other funds and business enterprises, the Fund, the investment manager, the subadvisor and their service providers are subject to the risk of cyber incidents occurring from time to time.

Market Trading The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. Any of these factors, among others, may lead to the Fund’s shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than NAV when you buy shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those shares in the secondary market. The sub-advisor cannot predict whether shares will trade above (premium), below (discount) or at NAV.

Authorized Participant Concentration Only an authorized participant (Authorized Participant) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that act as Authorized Participants. To the extent that these institutions exit the business or are unable to proceed with creation and/or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units (as defined below), Fund shares may trade at a discount to NAV and possibly face trading halts and/or delisting. This risk may be more pronounced in volatile markets, potentially where there are significant redemptions in ETFs generally.

Cash Transactions Unlike certain ETFs, the Fund expects to generally effect its creations and redemptions entirely for cash, rather than for in-kind securities. Therefore, it may be required to sell portfolio securities and subsequently recognize gains on such sales that the Fund might not have recognized if it were to distribute portfolio securities in-kind. As such, investments in Fund shares may be less tax-efficient than an investment in an ETF that distributes portfolio securities entirely in-kind.

Small Fund When the Fund's size is small, the Fund may experience low trading volume and wide bid/ask spreads. In addition, the Fund may face the risk of being delisted if the Fund does not meet certain conditions of the listing exchange.

Large Shareholder Certain shareholders, including other funds or accounts advised by the investment manager or an affiliate of the investment manager, may from time to time own a substantial amount of the Fund’s shares. In addition, a third-party investor, the investment manager or an affiliate of the investment manager, an authorized participant, a lead market maker, or another entity may invest in the Fund and hold its investment for a limited period of time solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

Portfolio Managers

Purchase and Sale of Fund Shares

The Fund is an ETF. Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund issues or redeems shares that have been aggregated into blocks of 50,000 shares or multiples thereof (Creation Units) to Authorized Participants who have entered into agreements with the Fund’s distributor, Franklin Distributors, LLC. The Fund will generally issue or redeem Creation Units in exchange for a basket of securities (which may include cash in lieu of certain securities) and/or an amount of cash that the Fund specifies each day.

An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the Fund (bid) and the lowest price a seller is willing to accept for shares of the Fund (ask) when buying or selling shares in the secondary market (the “bid-ask spread”). Recent information, including information on the Fund’s NAV, market price, premiums and discounts, and bid-ask spreads will be available on the Fund’s website at https://www.franklintempleton.com/investor/investments-and-solutions/investment-options/etfs/.

Taxes

The Fund’s distributions are generally taxable to you as ordinary income, capital gains, or some combination of both, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or an individual retirement account, in which case your distributions would generally be taxed when withdrawn from the tax-advantaged account.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), the investment manager or other related companies may pay the intermediary for certain Fund-related activities, including those that are designed to make the intermediary more knowledgeable about exchange traded products, such as the Fund, as well as for marketing, education or other initiatives related to the sale or promotion of Fund shares. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

Fund Details

Investment Goal

The Fund’s investment goal is to maximize total return consistent with prudent investment management and liquidity needs. The Fund’s investment goal is non-fundamental, which means it may be changed by the board of trustees without shareholder approval. Shareholders will be given at least 60 days’ advance notice of any change to the Fund’s investment goal.

Principal Investment Policies and Practices

The Fund invests in a portfolio comprised of debt instruments and fixed income securities of various maturities. Under normal market conditions, the Fund will seek its investment objective by investing at least 80% of its net assets, including the amount of borrowing for investment purposes, if any, in debt and fixed income securities (Principal Investments). As part of its 80% policy, the Fund intends to invest in derivatives that (i) provide exposure to the Principal Investments, (ii) are used to risk manage the Fund’s holdings, and/or (iii) are used to enhance returns. The risk management uses of derivatives will include managing (i) investment-related risks, (ii) risks due to fluctuations in securities prices or interest rates, (iii) risks due to the credit-worthiness of an issuer, and (iv) the effective duration of the Fund’s portfolio. Shareholders will be given at least 60 days' advance notice of any change to the Fund's 80% policy.

The types of derivatives in which the Fund will invest include swaps and security-based swaps, futures and options on futures, swaptions and security options. The Fund may also hold U.S. Treasury securities, cash and cash equivalents. 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 sub-advisor. 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 types of fixed income securities in which the Fund may invest include corporate debt securities, U.S. and non-U.S. government securities, asset-backed securities (“ABS”), mortgage-backed securities (“MBS”) (including commercial MBS (“CMBS”), residential MBS (“RMBS”) and non-agency collateralized mortgage obligations (“CMOs”)), collateralized debt obligations (“CDOs”) and mortgage dollar rolls. The fixed income securities and debt instruments in which the Fund may invest may pay fixed, variable or floating rates of interest. The Fund will not invest more than 10% of the Fund’s total assets in CDOs. The Fund will also not invest more than 20% of its total assets in bank loans including junior loans (e.g., debt instruments that are unsecured and subordinated).

The Fund may invest up to 20% of its assets in below investment grade fixed income securities or debt instruments. For these purposes, “investment grade” is defined as investments with a rating at the time of purchase in one of the four highest categories of at least one nationally recognized statistical rating organization (“NRSRO”) (e.g., BBB- or higher or Baa3 or higher) or, if unrated, securities of comparable quality at the time of purchase (as determined by the sub-advisor). Securities rated below investment grade (e.g., BB+ to D or Baa1 to C) or, if unrated, securities of comparable quality at the time of purchase (as determined by the sub-advisor) are commonly known as “junk bonds” or “high yield securities.” However, ratings by the independent rating agencies are relative and subjective, are not absolute standards of quality, and do not evaluate the market risk of securities.

If, subsequent to its purchase a security is downgraded in rating or goes into default, the Fund will consider such events in its evaluation of the overall investment merits of that security but will not necessarily dispose of the security immediately. Many debt securities of non-U.S. issuers, and especially developing or emerging market issuers, are rated below investment grade or are unrated so that their selection depends on the sub-advisor’s internal analysis. The Fund may invest in asset-backed securities, mortgage-backed securities and mortgage dollar rolls. An asset-backed security is a security backed by loans, leases, and other receivables. A mortgage-backed security is an interest in a pool of mortgage loans made by and packaged or “pooled” together by banks, mortgage lenders, various governmental agencies and other financial institutions for sale to investors to finance purchases of homes, commercial buildings and other real estate. In a mortgage dollar roll, the Fund sells mortgage-backed securities for delivery in the current month and simultaneously contracts to repurchase substantially similar (same type, coupon, and maturity) securities on a specified future date. During the period between the sale and repurchase, the Fund forgoes principal and interest paid on the mortgage-backed securities. The Fund earns money on a mortgage dollar roll from any difference between the sale price and the future purchase price, as well as the interest earned on the cash proceeds of the initial sale.

Collateralized mortgage obligations (“CMOs”) are debt obligations collateralized by mortgage loans or mortgage pass-through securities. CMOs are a type of mortgage-backed security. Typically, CMOs are collateralized by Ginnie Mae, Fannie Mae or Freddie Mac Certificates, but may also 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.

The Fund may invest in securities issued by both U.S. and non-U.S. issuers (including issuers in emerging markets) but the Fund will not invest more than 25% of its total assets in the securities or debt instruments of non-U.S. issuers. The Fund presently intends to limit its investments to U.S. dollar denominated securities.

The Fund may engage in active and frequent trading as part of its investment strategies.

The Fund may also hold equity securities of any type acquired in reorganizations of issuers of fixed income securities or debt instruments (“work out securities”), non-convertible preferred securities, warrants and exchange-traded funds (“ETFs”) that provide exposure to these investments.

Western Asset’s investment process combines top-down and bottom-up analyses. Western Asset’s US Broad Strategy Committee, which is chaired by the Chief Investment Officer, leads the investment process by considering macro-economic and securities-specific insights and ideas covering all major bond market segments from all of its macro-economic and credit research teams around the globe, and formulates the broad top-down investment outlook, including a set of strategies around duration, yield curve, country, currency  and sector.  The US Broad Market portfolios team is ultimately responsible for the Fund’s portfolio construction, making sure that allocations are consistent with Western Asset’s overall investment themes while adhering to strategy risk/return profiles and specific guidelines. This includes duration, curve, country, currency and sector positioning. The portfolio managers of the Fund are S. Kenneth Leech, Mark S. Lindbloom, Julien A. Scholnick, Frederick R. Marki and John L. Bellows. These investment professionals, all of whom are employed by Western Asset, work together with a broader investment management team (collectively, the “Investment Professionals”).

The Investment Professionals conduct bottom-up fundamental research and provide input into the top-down perspectives. “A top-down view” incorporates macro-economic views on growth, inflation, and fiscal and monetary policy, as well as views on sectors (such as corporates which trade at spreads over U.S. Treasuries) and current general market conditions and valuation levels. This top-down view translates into a set of strategies regarding duration, yield curve, country, currency and sector. The Investment Professionals provide fundamental analysis at sector and subsector levels. Incorporating the macro-economic views of the US Broad Strategy Committee and the risk profile of the Fund’s portfolio, the Investment Professionals balance these inputs with their industry/issuer insights in setting sector overweights and underweights. “Bottom up fundamental research” involves detailed analysis of individual securities, issuers, sectors and sub-sectors. The Investment Professionals use a security-specific process in order to assess whether securities are mispriced or undervalued in their opinion and select securities for the Fund’s portfolio. The Investment Professionals conduct an ongoing assessment of changing credit characteristics and of securities with characteristics such as assets perceived to be overlooked or under-appreciated, floating or fixed interest rates, credit quality and securities issued in mergers, as well as newly-issued securities. Using sector and issue analyses, the Investment Professionals select issues opportunistically in order to exploit perceived mispricings versus long-term fundamental value that exist in the market.  The sub-advisor monitors a broad set of factors that may prompt it to consider selling or reducing a position focused on the risk/reward characteristics of a credit. Factors include the following: whether total return and/or valuation targets have been realized, whether there have been significant changes in macro/micro economic analyses indicating that sector emphasis should be changed, whether industry conditions have deteriorated, whether the issuer has changed its business strategy, whether credit fundamentals have deteriorated and whether the sub-advisor finds better relative value elsewhere in the bond market.

The Fund is an actively managed ETF and, thus, does not seek to replicate the performance of a specified index. Accordingly, the investment manager has discretion on a daily basis to manage the Fund’s portfolio in accordance with the Fund’s investment goal.

Principal Risks

Market

The market values of securities or other investments owned by the Fund will go up or down, sometimes rapidly or unpredictably. The Fund’s investments may decline in value due to factors affecting individual issuers (such as the results of supply and demand), or sectors within the securities markets. The value of a security or other investment also may go up or down due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in interest rates or exchange rates, or adverse investor sentiment generally. In addition, unexpected events and their aftermaths, such as the spread of diseases; natural, environmental or man-made disasters; financial, political or social disruptions; terrorism and war; and other tragedies or catastrophes, can cause investor fear and panic, which can adversely affect the economies of many companies, sectors, nations, regions and the market in general, in

ways that cannot necessarily be foreseen. During a general downturn in the securities markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that securities or other investments held by the Fund will participate in or otherwise benefit from the advance.

The global outbreak of the novel strain of coronavirus, COVID-19, has resulted in market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain the spread of COVID-19 have resulted in global travel restrictions and disruptions of healthcare systems, business operations and supply chains, layoffs, volatility in consumer demand for certain products, defaults and credit ratings downgrades, and other significant economic impacts. The effects of the COVID-19 pandemic have impacted global economic activity across many industries and may heighten other pre-existing political, social and economic risks, locally or globally. The full impact of the COVID-19 pandemic, and other epidemics and pandemics that may arise in the future, on national and global economies, individual companies and the financial markets is unpredictable, may result in a high degree of uncertainty for potentially extended periods of time and may adversely affect the Fund’s performance.

Interest Rate

Interest rate changes can be sudden and unpredictable, and are influenced by a number of factors, including government policy, monetary policy, inflation expectations, perceptions of risk, and supply of and demand for bonds. Changes in government or central bank policy, including changes in tax policy or changes in a central bank’s implementation of specific policy goals, may have a substantial impact on interest rates. There can be no guarantee that any particular government or central bank policy will be continued, discontinued or changed, nor that any such policy will have the desired effect on interest rates. Debt securities generally tend to lose market value when interest rates rise and increase in value when interest rates fall. A rise in interest rates also has the potential to cause investors to rapidly sell fixed income securities. A substantial increase in interest rates may also have an adverse impact on the liquidity of a debt security, especially those with longer maturities or durations. Securities with longer maturities or durations or lower coupons or that make little (or no) interest payments before maturity tend to be more sensitive to interest rate changes. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. In addition, low interest rate environments may prevent a debt fund from paying expenses out of its assets if its earned income is insufficient to cover expenses.

Mortgage Securities and Asset-Backed Securities

Mortgage securities differ from conventional debt securities because principal is paid back over the life of the security rather than at maturity. The Fund may receive unscheduled prepayments of principal due to voluntary prepayments, refinancing or foreclosure on the underlying mortgage loans. To the Fund this means a loss of anticipated interest, and a portion of its principal investment represented by any premium the Fund may have paid. Mortgage prepayments generally increase when interest rates fall. Because of prepayments, mortgage securities may be less effective than some other types of debt securities as a means of "locking in" long-term interest rates and may have less potential for capital appreciation during periods of falling interest rates. When the Fund reinvests the prepayments of principal it receives, it may receive a rate of interest that is lower than the rate on the existing security.

Mortgage securities also are subject to extension risk. An unexpected rise in interest rates could reduce the rate of

prepayments on mortgage securities and extend their life. This could cause the price of the mortgage securities and the Fund's share price to fall and would make the mortgage securities more sensitive to interest rate changes.

Since September 2008, the Federal Housing Finance Agency (FHFA), an agency of the U.S. government, has acted as the conservator to operate Fannie Mae and Freddie Mac until they are stabilized. It is unclear how long the conservatorship will last or what effect this conservatorship will have on the securities issued or guaranteed by Fannie Mae or Freddie Mac for the long-term.

Although the mortgage-backed securities that are delivered in TBA transactions must meet certain standards, there is a risk that the actual securities received by the Fund may be less favorable than what was anticipated when entering into the transaction. TBA transactions also involve the risk that a counterparty will fail to deliver the security, exposing the Fund to losses. Whether or not the Fund takes delivery of the securities at the termination date of a TBA transaction, it will nonetheless be exposed to changes in the value of the underlying investments during the term of the agreement.

Issuers of asset-backed securities may have limited ability to enforce the security interest in the underlying assets, and credit enhancements provided to support the securities, if any, may be inadequate to protect investors in the event of default. Like mortgage securities, asset-backed securities are subject to prepayment and extension risks.

Mortgage Dollar Rolls

Derivative Instruments

The performance of derivative instruments depends largely on the performance of an underlying instrument, such as a security, interest rate or index, and such instruments often have risks similar to the underlying instrument, in addition to other risks. Derivative instruments involve costs and can create economic leverage in the Fund's portfolio, which may result in significant volatility and cause the Fund to participate in losses (as well as gains) in an amount that significantly exceeds the Fund's initial investment. Other risks include illiquidity, mispricing or improper valuation of the derivative instrument, and imperfect correlation between the value of the derivative and the underlying instrument so that the Fund may not realize the intended benefits. Their successful use will usually depend on the sub-advisor’s ability to accurately forecast movements in the market relating to the underlying instrument. Should a market or markets, or prices of particular classes of investments move in an unexpected manner, especially in unusual or extreme market conditions, the Fund may not realize the anticipated benefits of the transaction, and it may realize losses, which could be significant. If the sub-advisor is not successful in using such derivative instruments, the Fund’s performance may be worse than if the sub-advisor did not use such derivative instruments at all. When a derivative is used for hedging, the change in value of the derivative instrument also may not correlate specifically with the security, interest rate or other risk being hedged. There is also the risk, especially under extreme market conditions, that an instrument, which usually would operate as a hedge, provides no hedging benefits at all.

Use of these instruments could also result in a loss if the counterparty to the transaction does not perform as promised, including because of such counterparty’s bankruptcy or insolvency. This risk is heightened with respect to over-the-counter (OTC) instruments, such as certain swap agreements, and may be greater during volatile market conditions. Other risks include the inability to close out a position because the trading market becomes illiquid (particularly in the OTC markets) or the availability of counterparties becomes limited for a period of time. In addition, the presence of speculators in a particular market could lead to price distortions. To the extent that the Fund is unable to close out a position because of market illiquidity, the Fund may not be able to prevent further losses of value in its derivatives holdings. Some derivatives can be particularly sensitive to changes in interest rates or other market prices. Investors should bear in mind that, while the Fund intends to use derivative strategies on a regular basis, it is not obligated to actively engage in these transactions, generally or in any particular kind of derivative, if the sub-advisor elects not to do so due to availability, cost or other factors.

Many swaps currently are, and others eventually are expected to be, required to be cleared through a central counterparty. Central clearing is designed to reduce counterparty credit risk and increase liquidity compared to OTC swaps, but it does not eliminate those risks completely. With cleared swaps, there is also a risk of loss by the Fund of its initial and variation margin

deposits in the event of bankruptcy of the futures commission merchant (FCM) with which the Fund has an open position, or the central counterparty in a swap contract. With cleared swaps, the Fund may not be able to obtain as favorable terms as it would be able to negotiate for a bilateral, uncleared swap. In addition, an FCM may unilaterally amend the terms of its agreement with the Fund, which may include the imposition of position limits or additional margin requirements with respect to the Fund’s investment in certain types of swaps. The regulation of cleared and uncleared swaps, as well as other derivatives, is a rapidly changing area of law and is subject to modification by government and judicial action. In addition, the SEC, Commodity Futures Trading Commission (CFTC) and the exchanges are authorized to take extraordinary actions in the event of a market emergency. It is not possible to predict fully the effects of current or future regulation.

The use of derivative strategies may also have a tax impact on the Fund. The timing and character of income, gains or losses from these strategies could impair the ability of the sub-advisor to use derivatives when it wishes to do so.

Income

The Fund's distributions to shareholders may decline when prevailing interest rates fall, when the Fund experiences defaults on debt securities it holds or when the Fund realizes a loss upon the sale of a debt security. The Fund's income generally declines during periods of falling benchmark interest rates because the Fund must reinvest the proceeds it receives from existing investments (upon their maturity, prepayment, amortization, sale, call, or buy-back) at a lower rate of interest or return.

Prepayment

Debt securities are subject to prepayment risk when the issuer can "call" the security, or repay principal, in whole or in part, prior to the security's maturity. When the Fund reinvests the prepayments of principal it receives, it may receive a rate of interest that is lower than the rate on the existing security, potentially lowering the Fund's income, yield and its distributions to shareholders. Securities subject to partial or complete prepayment(s) may offer less potential for gains during a declining interest rate environment and have greater price volatility. Prepayment risk is greater in periods of falling interest rates for fixed-rate investments, and for floating or variable rate securities, rising interest rates generally increase the risk of refinancings or prepayments.

Extension

The market value of some debt securities will be adversely affected when bond calls or prepayments on underlying assets are less or slower than anticipated, particularly when interest rates rise. When that occurs, the effective maturity date of the Fund’s investment may be extended, resulting in an increase in interest rate sensitivity to that of a longer-term instrument. Such extension may also effectively lock-in a below market interest rate and reduce the value of the debt security.

Foreign Securities (non-U.S.)

Investing in foreign securities, including sovereign debt securities, typically involves more risks than investing in U.S. securities. Certain of these risks also may apply to securities of U.S. companies with significant foreign operations.

Currency exchange rates.  Foreign securities may be issued and traded in foreign currencies. As a result, their market values in U.S. dollars may be affected by changes in exchange rates between such foreign currencies and the U.S. dollar, as well as between currencies of countries other than the U.S. For example, if the value of the U.S. dollar goes up compared to a foreign currency, an investment traded in that foreign currency will go down in value because it will be worth fewer U.S. dollars. The Fund accrues additional expenses when engaging in currency exchange transactions, and valuation of the Fund's foreign securities may be subject to greater risk because both the currency (relative to the U.S. dollar) and the security must be considered.

Political and economic developments. The political, economic and social policies or structures of some foreign countries may be less stable and more volatile than those in the United States. Investments in these countries may be subject to greater risks of internal and external conflicts, expropriation, nationalization of assets, foreign exchange controls (such as suspension of the ability to transfer currency from a given country), restrictions on removal of assets, political or social instability, military action or unrest, diplomatic developments, currency devaluations, foreign ownership limitations, and substantial, punitive or confiscatory tax increases. It is possible that a government may take over the assets or operations of a company or impose restrictions on the exchange or export of currency or other assets. Some countries also may have different legal systems that may make it difficult or expensive for the Fund to vote proxies, exercise shareholder rights, and pursue legal remedies with respect to its foreign investments. Diplomatic and political developments could affect the economies, industries, and securities and currency markets of the countries in which the Fund is invested. These developments include rapid and adverse political

changes; social instability; regional conflicts; sanctions imposed by the United States, other nations or other governmental entities, including supranational entities; terrorism; and war. In addition, such developments could contribute to the devaluation of a country’s currency, a downgrade in the credit ratings of issuers in such country, or a decline in the value and liquidity of securities of issuers in that country. An imposition of sanctions upon, or other government actions impacting, certain issuers in a country could result in (i) an immediate freeze of that issuer’s securities, impairing the ability of the Fund to buy, sell, receive or deliver those securities or (ii) other limitations on the Fund’s ability to invest or hold such securities. These factors would affect the value of the Fund’s investments and are extremely difficult, if not impossible, to predict and take into account with respect to the Fund's investments.

Sovereign debt securities.   Sovereign debt securities are subject to various risks in addition to those relating to debt securities and foreign securities generally, including, but not limited to, the risk that a governmental entity may be unwilling or unable to pay interest and repay principal on its sovereign debt, or otherwise meet its obligations when due because of cash flow problems, insufficient foreign reserves, the relative size of the debt service burden to the economy as a whole, the government’s policy towards principal international lenders such as the International Monetary Fund, or the political considerations to which the government may be subject. Sovereign debtors also may be dependent on expected disbursements from other foreign governments or multinational agencies and the country’s access to, or balance of, trade. If a sovereign debtor defaults (or threatens to default) on its sovereign debt obligations, the indebtedness may be restructured. Restructuring may include obtaining additional credit to finance outstanding obligations, reduction and rescheduling of payments of interest and principal, or negotiation of new or amended credit and security agreements. Unlike most corporate debt restructurings, the fees and expenses of financial and legal advisers to the creditors in connection with a restructuring may be borne by the holders of the sovereign debt securities instead of the sovereign entity itself. Some sovereign debtors have in the past been able to restructure their debt payments without the approval of some or all debt holders or to declare moratoria on payments, and similar occurrences may happen in the future.

In the event of a default on sovereign debt, the Fund may have limited legal recourse against the defaulting government entity. As a sovereign entity, the issuing government may be immune from lawsuits in the event of its failure or refusal to pay the obligations when due, and any rights the Fund may have may be restricted pursuant to the terms of applicable treaties with such sovereign entity. If a sovereign entity defaults, it may request additional time in which to pay or for further loans. There may be no legal process for collecting principal or interest payments on sovereign debt that a government does not pay or such legal process may be relatively more expensive, nor are there bankruptcy proceedings by which the Fund may collect in whole or in part on debt issued by a sovereign entity. In certain cases, remedies must be pursued in the courts located in the country of the defaulting sovereign entity itself, which may further limit the Fund’s ability to obtain recourse.

Trading practices. Brokerage commissions, withholding taxes, custodial fees, and other fees generally are higher in foreign markets. The policies and procedures followed by foreign stock exchanges, currency markets, trading systems and brokers may differ from those applicable in the United States, with possibly negative consequences to the Fund. The procedures and rules governing foreign trading, settlement and custody (holding of the Fund's assets) also may result in losses or delays in payment, delivery or recovery of money or other property. Foreign government supervision and regulation of foreign securities and currency markets and trading systems may be less than or different from government supervision in the United States, and may increase the Fund's regulatory and compliance burden and/or decrease the Fund's investor rights and protections.

Availability of information. Foreign issuers may not be subject to the same disclosure, accounting, auditing and financial reporting standards and practices as U.S. issuers. Thus, there may be less information publicly available about foreign issuers than about most U.S. issuers. In addition, information provided by foreign issuers may be less timely or less reliable than information provided by U.S. issuers.

Limited markets. Certain foreign securities may be less liquid (harder to sell) and their prices may be more volatile than many U.S. securities. Illiquidity tends to be greater, and valuation of the Fund's foreign securities may be more difficult, due to the infrequent trading and/or delayed reporting of quotes and sales. If the Fund’s underlying portfolio holdings are illiquid, the Fund’s shares may become less liquid in response to deteriorating liquidity in the market for the underlying portfolio holdings, and the Fund’s market price could deviate from the Fund’s NAV.

Regional.  Adverse conditions in a certain region or country can adversely affect securities of issuers in other countries whose economies appear to be unrelated. To the extent that the Fund invests a significant portion of its assets in a specific geographic region or a particular country, the Fund will generally have more exposure to the specific regional or country economic risks. In the event of economic or political turmoil or a deterioration of diplomatic relations in a region or country where a substantial portion of the Fund’s assets are invested, the Fund may experience substantial illiquidity or reduction in the value of the Fund’s investments.

The risk of investments in Europe may be heightened due to the January 31, 2020 departure of the United Kingdom from the European Union (EU) and resulting uncertainty concerning the economic consequences of the departure as well as Russia's military invasion of Ukraine in February 2022, each of which may cause increased market volatility.

Emerging Market Countries

The Fund's investments in emerging market issuers are subject to all of the risks of foreign investing generally, and have additional heightened risks due to a lack of established legal, political, business and social frameworks to support securities markets. Some of the additional significant risks include:

Because of the above factors, the Fund's investments in emerging market issuers may be subject to greater price volatility and illiquidity than investments in developed markets.

Certain corporate loans may not be considered “securities,” and investors, such as the Fund, therefore may not be entitled to rely on the antifraud protections of the federal securities laws and may have limited legal remedies.

The senior secured corporate loans and corporate debt securities in which the Fund invests are often issued in connection with highly leveraged transactions. Such transactions include leveraged buyout loans, leveraged recapitalization loans, and other types of acquisition financing. Loan investments issued in such transactions are subject to greater credit risks than other investments including a greater possibility that the borrower may default or enter bankruptcy. Such floating rate investments may be rated below investment grade (i.e., also known as "junk bonds"). Although loan investments are generally subject to certain restrictive covenants in favor of the investors, many of these loans may from time to time be reissued or offered as “covenant lite” loans, which may entail potentially increased risk, because they may have fewer or no financial maintenance covenants or restrictions that would normally allow for early intervention and proactive mitigation of credit risk.

In the event of a breach of a covenant in non-covenant lite loans or debt securities, lenders may have the ability to intervene and either prevent or restrict actions that may potentially compromise the company's ability to pay or lenders may be in a position to obtain concessions from the borrowers in exchange for a waiver or amendment of the specific covenant(s). In contrast, covenant lite loans do not always or necessarily offer the same ability to intervene or obtain additional concessions from borrowers. This risk is offset to varying degrees by the fact that the same financial and performance information may be available with or without covenants to lenders and the public alike and can be used to detect such early warning signs as deterioration of a borrower’s financial condition or results. With such information, the portfolio managers are normally able to take appropriate actions without the help of covenants in the loans or debt securities. Covenant lite corporate loans and debt securities, however, may foster a capital structure designed to avoid defaults by giving borrowers or issuers increased financial flexibility when they need it the most.

Impairment of Collateral

The terms of the senior secured corporate loans and corporate debt securities in which the Fund typically invests require that collateral and/or cash flow generating capacity be maintained to support payment of the obligation. Generally, the collateral for a secured corporate loan or corporate debt security has a fair market value at least equal to 100% of the amount of such corporate loan or corporate debt security when initially syndicated. However, the value of the collateral and/or the cash flow generating capacity may decline after the Fund invests and there is a risk that the value of the collateral may not be sufficient to cover the amount owed to the Fund. In addition, collateral securing a loan may be found invalid, may be used to pay other outstanding obligations of the borrower under applicable law or more senior claims under applicable credit agreements, or may be difficult to sell.

In the event that a borrower defaults, the Fund's access to the collateral may be limited by bankruptcy and other insolvency laws. There is also the risk that the collateral may be difficult to liquidate, or that a majority of the collateral may be illiquid. As a result, the Fund might not receive timely payments or may not ultimately receive payments to which it is entitled.

High-Yield Debt Securities

High-yield debt securities (including loans) and unrated securities of similar credit quality (high-yield debt instruments or junk bonds) involve greater risk of a complete loss of the Fund's investment, or delays of interest and principal payments, than higher-quality debt securities or loans. Issuers of high-yield debt instruments are not as strong financially as those issuing securities of higher credit quality. High-yield debt instruments are generally considered predominantly speculative by the applicable rating agencies as these issuers are more likely to encounter financial difficulties because they may be more highly leveraged, or because of other considerations. In addition, high yield debt securities generally are more vulnerable to changes in the relevant economy, such as a recession or a sustained period of rising interest rates, that could affect their ability to make interest and principal payments when due. If an issuer stops making interest and/or principal payments, payments on the securities may never resume. These instruments may be worthless and the Fund could lose its entire investment.

The prices of high-yield debt instruments generally fluctuate more than higher-quality securities. Prices are especially sensitive to developments affecting the issuer's business or operations and to changes in the ratings assigned by rating agencies. In addition, the entire high-yield debt market can experience sudden and sharp price swings due to changes in economic conditions, stock market activity, large sustained sales by major investors, a high-profile default, or other factors. Prices of corporate high-yield debt instruments often are closely linked with the company's stock prices and typically rise and fall in response to factors that affect stock prices.

High-yield debt instruments are generally less liquid than higher-quality securities. Many of these securities are not registered for sale under the federal securities laws and/or do not trade frequently. When they do trade, their prices may be significantly higher or lower than expected. At times, it may be difficult to sell these securities promptly at an acceptable price, which may

limit the Fund's ability to sell securities in response to specific economic events or to meet redemption requests. As a result, certain high-yield debt instruments generally pose greater illiquidity and valuation risks.

Substantial declines in the prices of high-yield debt instruments can dramatically increase the yield of such instruments. The decline in market prices generally reflects an expectation that the issuer(s) may be at greater risk of defaulting on the obligation to pay interest and principal when due. Therefore, substantial increases in yield may reflect a greater risk by the Fund of losing some or part of its investment rather than reflecting any increase in income from the higher yield that the debt instrument may pay to the Fund on its investment.

Debt Securities Ratings

The use of credit ratings in evaluating debt securities can involve certain risks, including the risk that the credit rating may not reflect the issuer's current financial condition or events since the security was last rated by a rating agency. Credit ratings may be influenced by conflicts of interest or based on historical data that no longer apply or that are no longer accurate.

When-Issued and Delayed Delivery Transactions

Mortgage-backed securities may be issued on a when-issued or delayed delivery basis, where payment and delivery take place at a future date. Because the market price of the security may fluctuate during the time before payment and delivery, the Fund assumes the risk that the value of the security at delivery may be more or less than the purchase price.

Credit-Linked Securities

The Fund bears the risk of loss of its principal investment and the periodic interest payments expected to be received in the event that one or more of the underlying debt obligations or debt obligations underlying the credit default swaps go into default or otherwise become non-performing. Credit-linked securities are typically structured as limited recourse obligations and the Fund bears the risk that the issuer will default or become bankrupt. An investment in credit-linked securities also involves reliance on the counterparty to the swap entered into with the issuer to make periodic payments to the issuer under the terms of the credit default swap. The market for credit-linked securities may be, or suddenly can become, illiquid. Changes in liquidity may result in significant, rapid and unpredictable changes in the prices for credit-linked securities. The value of a credit-linked security will typically increase or decrease with any change in value of the underlying debt obligations, if any, held by the issuer and the credit default swap. Further, in cases where the credit-linked security is structured such that the payments to the Fund are based on amounts received in respect of, or the value of performance of, any underlying debt obligations specified in the terms of the relevant credit default swap, fluctuations in the value of such obligation may affect the value of the credit-linked security. The collateral of a credit-linked security may be one or more credit default swaps, which are subject to additional risks.

Variable Rate Securities

Variable rate securities (which include floating rate debt securities) generally are less price sensitive to interest rate changes than fixed rate debt securities. However, the market value of variable rate debt securities may decline or not appreciate as quickly as expected when prevailing interest rates rise if the interest rates of the variable rate securities do not rise as much, or as quickly, as interest rates in general. Conversely, variable rate securities will not generally increase in market value if interest rates decline. When interest rates fall, there may be a reduction in the payments of interest received by the Fund from its variable rate securities.

The NAV and trading price of the Fund may decline or not appreciate as expected during periods of rising interest rates until the interest rates on these securities reset to market rates. You could lose money if you sell your shares of the Fund before these rates reset.

Focus

The greater the Fund's exposure to any single type of investment – including investment in a given industry, sector, region, country, issuer, or type of security – the greater the losses the Fund may experience upon any single economic, market, business, political, regulatory, or other occurrence. As a result, there may be more fluctuation in the price of the Fund's shares.

Cash/Cash Equivalents

To the extent the Fund holds cash or cash equivalents rather than securities in which it primarily invests or uses to manage risk, the Fund may not achieve its investment objectives and may underperform.

Management

The Fund is actively managed and could experience losses if the sub-advisor’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund's portfolio prove to be incorrect. There can be no guarantee that these techniques or the sub-advisor's investment decisions will produce the desired results. Additionally, legislative, regulatory, or tax developments may affect the investment techniques available to the sub-advisor in connection with managing the Fund and may also adversely affect the ability of the Fund to achieve its investment goal.

Portfolio Turnover

The sub-advisor will sell a security or enter or close out of a derivative position when it believes it is appropriate to do so, regardless of how long the Fund has held the security. The Fund's turnover rate may exceed 100% per year because of the anticipated use of certain investment strategies. The rate of portfolio turnover will not be a limiting factor for the sub-advisor in making decisions on when to buy or sell securities. High turnover will increase the Fund's transaction costs and may increase your tax liability if the transactions result in capital gains.

LIBOR Transition

The Fund invests in financial instruments that may have floating or variable rate calculations for payment obligations or financing terms based on the London Interbank Offered Rate (LIBOR), which is the benchmark interest rate at which major global banks lend to one another in the international interbank market for short-term loans. In 2017, the U.K. Financial Conduct Authority announced its intention to cease compelling banks to provide the quotations needed to sustain LIBOR after 2021. Although many LIBOR rates were phased out at the end of 2021 as originally intended, a selection of widely used USD LIBOR rates will continue to be published until June 2023 in order to assist with the transition to an alternative rate. In March 2022, the U.S. federal government enacted legislation to establish a process for replacing LIBOR in certain existing contracts that do not already provide for the use of a clearly defined or practicable replacement benchmark rate as described in the legislation. Generally speaking, for contracts that do not contain a fallback provision as described in the legislation, a benchmark replacement recommended by the Federal Reserve Board will effectively automatically replace the USD LIBOR benchmark in the contract after June 30, 2023. The recommended benchmark replacement will be based on the Secured Overnight Financing Rate (SOFR) published by the Federal Reserve Bank of New York, including certain spread adjustments and benchmark replacement conforming changes. The ultimate impact of the discontinuation of LIBOR and the transition to an alternative rate on the Fund's portfolio and markets generally remains uncertain. There can be no guarantee that financial instruments that transition to an alternative reference rate will retain the same value or liquidity as they would otherwise have had. Since the usefulness of LIBOR as a benchmark could also deteriorate during the transition period, effects could occur at any time.

Cybersecurity

Cybersecurity incidents, both intentional and unintentional, 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 investment manager, the sub-advisor, authorized participants, or index providers (as applicable) and listing exchanges, 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 shares or receiving distributions. The investment manager and sub-advisor 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 investment manager or the sub-advisor. Cybersecurity incidents may result in financial losses to the Fund and its shareholders, and substantial costs may be incurred in an effort to prevent or mitigate future cybersecurity incidents. Issuers of securities in which the Fund invests are also subject to cybersecurity risks, and the value of these securities could decline if the issuers experience cybersecurity incidents.

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

Absence of active market. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained. There are no obligations of market makers to make a market in the Fund’s shares or of an Authorized Participant to submit purchase or redemption orders for Creation Units. Decisions by market makers or Authorized Participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying value of the Fund’s portfolio securities and the Fund’s market price. This reduced effectiveness could result in Fund shares trading at a premium or discount to its NAV and also greater than normal intraday bid/ask spreads. Additionally, in stressed market conditions, the market for the Fund’s shares may become less liquid in response to deteriorating liquidity in the markets for the Fund’s portfolio holdings, which may cause a significant variance in the market price of the Fund’s shares and their underlying value and wider bid/ask spreads.

Secondary listings. The Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained, and may otherwise be made available to non-U.S. investors through funds or structured investment vehicles similar to depositary receipts.

The Fund’s shares may be less actively traded in certain markets than in others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary market trading. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders. To the extent that the underlying securities held by the Fund trade on an exchange that is closed when the securities exchange on which the Fund shares list and trade is open, there may be market uncertainty about the stale security pricing (i.e., the last quote from its closed foreign market) resulting in premiums or discounts to NAV that may be greater than those experienced by other ETFs.

There can be no assurance that the Fund’s shares will continue to trade on a stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market, or that such requirements will remain unchanged. Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market.

During a “flash crash,” the market prices of the Fund’s shares may decline suddenly and significantly. Such a decline may not reflect the performance of the portfolio securities held by the Fund. Flash crashes may cause Authorized Participants and other market makers to limit or cease trading in the Fund’s shares for temporary or longer periods. Shareholders could suffer significant losses to the extent that they sell shares at these temporarily low market prices.

Shares of the Fund, similar to shares of other issuers listed on a stock exchange, may be sold short and are therefore subject to the risk of increased volatility associated with short selling.

Premium/Discount. Shares of the Fund may trade at prices other than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings since the most recent calculation. The trading prices of the Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. As a result, the trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility.

Any of these factors, among others, may lead to the Fund’s shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than NAV when you buy shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those shares in the secondary market. The sub-advisor cannot predict whether shares will trade above (premium), below (discount) or at NAV. However, because shares can be created and redeemed in Creation Units at NAV, the sub-advisor believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or extreme market volatility may result in trading prices for shares of the Fund that differ significantly from its NAV.

Cost of buying or selling Fund shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the

“spread,” that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Authorized Participant Concentration

Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that act as Authorized Participants. To the extent that these institutions exit the business or are unable to proceed with creation and/or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may trade at a discount to NAV and possibly face trading halts and/or delisting. This risk may be more pronounced in volatile markets, potentially where there are significant redemptions in ETFs generally.

Cash Transactions

ETFs generally are able to make in-kind redemptions and avoid being taxed on gain on the distributed portfolio securities at the Fund level. To the extent that the Fund effects redemptions partly or entirely in cash, rather than in-kind, it may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds. If the Fund recognizes gain on these sales, this generally will cause the Fund to recognize gain it might not otherwise have recognized, or to recognize such gain sooner than would otherwise be required if it were to distribute portfolio securities in-kind. The Fund generally intends to distribute these gains to shareholders to avoid being taxed on this gain at the Fund level and otherwise comply with the special tax rules that apply to it. This strategy may cause shareholders to be subject to tax on gains they would not otherwise be subject to, or at an earlier date than, if they had made an investment in a different ETF. Moreover, cash transactions may have to be carried out over several days if the securities market is relatively illiquid and may involve considerable brokerage fees and taxes. These brokerage fees and taxes, which will be higher than if the Fund sold and redeemed its shares principally in-kind, could be imposed on the Fund and thus decrease the Fund's NAV to the extent they are not offset by the creation and redemption transaction fees paid by purchasers and redeemers of Creation Units.

Small Fund

When the Fund’s size is small, the Fund may experience low trading volume and wide bid/ask spreads. In addition, the Fund may face the risk of being delisted if the Fund does not meet certain conditions of the listing exchange. If the Fund were to be required to delist from the listing exchange, the value of the Fund may rapidly decline and performance may be negatively impacted. In addition, any resulting liquidation of the Fund could cause the Fund to incur elevated transaction costs for the Fund and negative tax consequences for its shareholders.

Large Shareholder

Certain large shareholders, including other funds or accounts advised by the investment manager, sub-advisor or an affiliate of the investment manager or sub-advisor, may from time to time own a substantial amount of the Fund’s shares. In addition, a third party investor, the investment manager, sub-advisor or an affiliate of the investment manager or sub-advisor, an authorized participant, a lead market maker, or another entity may invest in the Fund and hold its investment for a limited period of time solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment. Dispositions of a large number of shares by these shareholders may adversely affect the Fund’s liquidity and net assets to the extent such transactions are executed directly with the Fund in the form of redemptions through an authorized participant, rather than executed in the secondary market. These redemptions may also force the Fund to sell portfolio securities when it might not otherwise do so, which may negatively impact the Fund’s NAV and increase the Fund’s brokerage costs. To the extent these large shareholders transact in shares on the secondary market, such transactions may account for a large percentage of the trading volume on the listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

Exclusion of Investment Manager from Commodity Pool Operator Definition

With respect to the Fund, the investment manager has claimed an exclusion from the definition of “commodity pool operator” (CPO) under the Commodity Exchange Act (CEA) and the rules of the Commodity Futures Trading Commission (CFTC) and, therefore, is not subject to CFTC registration or regulation as a CPO. In addition, with respect to the Fund, the investment manager is relying upon a related exclusion from the definition of “commodity trading advisor” (CTA) under the CEA and the rules of the CFTC.

The terms of the CPO exclusion require the Fund, among other things, to adhere to certain limits on its investments in commodity futures, commodity options and swaps, which in turn include non-deliverable currency forward contracts, as further described in the Fund’s Statement of Additional Information (SAI). Because the investment manager and the Fund intend to comply with the terms of the CPO exclusion, the Fund may, in the future, need to adjust its investment strategies, consistent with its investment goal(s), to limit its investments in these types of instruments. The Fund is not intended as a vehicle for trading in the commodity futures, commodity options, or swaps markets. The CFTC has neither reviewed nor approved the investment manager’s reliance on these exclusions, or the Fund, its investment strategies or this prospectus.

Temporary Investments

When the sub-advisor believes market or economic conditions are unfavorable for investors, the sub-advisor may invest up to 100% of the Fund’s assets in a temporary defensive manner by holding all or a substantial portion of its assets in cash, cash equivalents or other high quality short-term investments. Temporary defensive investments generally may include short-term U.S. government securities, high grade commercial paper, bank obligations, repurchase agreements, money market fund shares (including shares of an affiliated money market fund), and other money market instruments. The sub-advisor also may invest in these types of securities or hold cash while looking for suitable investment opportunities or to maintain liquidity. In these circumstances, the Fund may be unable to achieve its investment goal.

More detailed information about the Fund and its policies and risks can be found in the Fund’s SAI.

A description of the Fund’s policies and procedures regarding the release of portfolio holdings information is also available in the Fund’s SAI. The Fund discloses its portfolio holdings daily at https://www.franklintempleton.com/investor/investments-and-solutions/investment-options/etfs/.

The Fund’s SAI provides additional information about portfolio manager compensation, other accounts that they manage and their ownership of Fund shares.

A discussion regarding the basis for the board of trustees approving the investment management contract and sub-advisory agreement will be available in the Fund's initial shareholder report.

The Fund pays Advisers a unified management fee. Advisers pays Western Asset for its services. Pursuant to the investment management agreement with Franklin Templeton ETF Trust (Trust) on behalf of the Fund, Advisers reimburses the Fund for all acquired fund fees and expenses (such as those associated with the Fund’s investment in a Franklin Templeton money fund) and pays all of the ordinary operating expenses of the Fund, except for (i) the Fund’s management fee, (ii) payments under the Fund’s Rule 12b-1 plan (if any), (iii) brokerage expenses (including any costs incidental to transactions in portfolio securities or instruments), (iv) taxes, (v) interest (including borrowing costs and dividend expenses on securities sold short and overdraft charges), (vi) litigation expenses (including litigation to which the Trust or the Fund may be a party and indemnification of the Trustees and officers with respect thereto), and (vii) other non-routine or extraordinary expenses. The fee is equal to the annual rate of [    ]% of the average daily net assets of the Fund.

Manager of Managers Structure

The board of trustees has authorized the Fund to operate in a “manager of managers” structure whereby the investment manager can appoint and replace both affiliated and unaffiliated sub-advisors, and enter into, amend and terminate sub-advisory agreements with such sub-advisors, each subject to board approval but without obtaining prior shareholder approval (Manager of Managers Structure). The Fund will, however, inform shareholders of the hiring of any new sub-advisor within 90 days after the hiring. The Manager of Managers Structure provides the Fund with greater flexibility and efficiency and alleviates the need for the Fund to incur the expense and delays associated with obtaining shareholder approval of such subadvisory agreements.

Distributions and Taxes

Income and Capital Gain Distributions

The Fund intends to qualify as a regulated investment company under the Internal Revenue Code. As a regulated investment company, the Fund generally pays no federal income tax on the income and gains it distributes to you. The Fund intends to pay income dividends at least monthly from its net investment income. Capital gains, if any, may be paid by the Fund at least annually. The Fund may distribute income dividends and capital gains more frequently, if necessary, in order to reduce or eliminate federal excise or income taxes on the Fund. The amount of any distribution will vary, and there is no guarantee the Fund will pay either income dividends or capital gain distributions. Distributions in cash may be reinvested automatically in additional whole Fund shares only if the broker through whom you purchased the shares makes such option available.

Annual statements. After the close of each calendar year, you will receive tax information from the broker with respect to the federal income tax treatment of the Fund’s distributions and any taxable sales of Fund shares occurring during the prior calendar year. You may receive revised tax information if the Fund must reclassify its distributions or the broker must adjust the cost basis of any covered shares sold after you receive your tax information. Distributions declared in October, November or December to shareholders of record in such month and paid in January are taxable as if they were paid in December. Additional tax information about the Fund’s distributions is available at franklintempleton.com.

Avoid buying a dividend. At the time you purchase your Fund shares, the Fund’s net asset value may reflect undistributed income, undistributed capital gains, or net unrealized appreciation in the value of the portfolio securities held by the Fund. For taxable investors, a subsequent distribution to you of such amounts, although constituting a return of your investment, would be taxable. Buying shares in the Fund just before it declares an income dividend or capital gain distribution is sometimes known as “buying a dividend.”

Tax Considerations

If you are a taxable investor, Fund distributions are generally taxable to you as ordinary income, capital gains or some combination of both. This is the case whether you reinvest your distributions in additional Fund shares or receive them in cash.

Dividend income. Income dividends are generally subject to tax at ordinary rates. Income dividends reported by the Fund as qualified dividend income may be subject to tax by individuals at reduced long-term capital gains tax rates provided certain holding period requirements are met. Because the Fund invests primarily in debt securities, it is expected that either none or only a small portion of the Fund’s income dividends may be qualified dividends. Investment company dividends paid to you from interest earned on certain U.S. government securities may be exempt from state and local taxation, subject in some states to minimum investment or reporting requirements that must be met by the Fund. A return-of-capital distribution is generally not taxable but will reduce the cost basis of your shares, and will result in a higher capital gain or a lower capital loss when you later sell your shares.

Capital gains. Fund distributions of short-term capital gains are also subject to tax at ordinary rates. Fund distributions of long-term capital gains are taxable at the reduced long-term capital gains rates no matter how long you have owned your Fund shares. For single individuals with taxable income not in excess of $44,625 in 2023 ($89,250 for married individuals filing jointly), the long-term capital gains tax rate is 0%. For single individuals and joint filers with taxable income in excess of these amounts but not more than $492,300 or $553,850, respectively, the long-term capital gains tax rate is 15%. The rate is 20% for single individuals with taxable income in excess of $492,300 and married individuals filing jointly with taxable income in excess of $553,850. An additional 3.8% Medicare tax may also be imposed as discussed below.

Sales of exchange-listed shares. Currently, any capital gain or loss realized on the sale of Fund shares generally is treated as long-term capital gain or loss if the shares have been held for more than one year and as short-term capital gain or loss if the shares have been held for one year or less.

Cost basis reporting. Contact the broker through whom you purchased your Fund shares to obtain information with respect to the available cost basis reporting methods and elections for your account.

Taxes on creation and redemption of creation units. An Authorized Participant who exchanges securities for Creation Units generally will recognize a gain or loss. The gain or loss will be equal to the difference between the market value of the Creation Units at the time of purchase and the exchanger’s aggregate basis in the securities surrendered plus any cash paid for the Creation Units. An Authorized Participant who exchanges Creation Units for securities will generally recognize a gain or loss equal to the difference between the exchanger’s basis in the Creation Units and the aggregate market value of the securities and the amount of cash received. The Internal Revenue Service, however, may assert that a loss realized upon an exchange of securities for Creation Units cannot be deducted currently under the rules governing “wash sales,” or on the basis that there has been no significant change in economic position. Authorized Participants exchanging securities should consult their own tax advisor with respect to whether wash sale rules apply and when a loss might be deductible.

Authorized Participants that create or redeem Creation Units will be sent a confirmation statement showing how many shares they purchased or sold and at what price.

Under current federal tax laws, any capital gain or loss realized upon a redemption of Creation Units is generally treated as long-term capital gain or loss if the shares have been held for more than one year and as a short-term capital gain or loss if the shares have been held for one year or less.

If the Fund redeems Creation Units in part or entirely in cash, it may recognize more capital gains than it will if it redeems Creation Units in-kind.

Medicare tax. An additional 3.8% Medicare tax is imposed on certain net investment income (including ordinary dividends and capital gain distributions received from the Fund and net gains from the sales of Fund shares) of U.S. individuals, estates and trusts to the extent that such person’s “modified adjusted gross income” (in the case of an individual) or “adjusted gross income” (in the case of an estate or trust) exceeds a threshold amount. Any liability for this additional Medicare tax is reported on, and paid with, your federal income tax return.

Backup withholding. A shareholder may be subject to backup withholding on any distributions of income, capital gains, or proceeds from the sale of Fund shares if the shareholder has provided either an incorrect tax identification number or no number at all, is subject to backup withholding by the IRS for failure to properly report payments of interest or dividends, has failed to certify that the shareholder is not subject to backup withholding, or has not certified that the shareholder is a U.S. person (including a U.S. resident alien). The backup withholding rate is currently 24%. State backup withholding may also apply.

State, local and foreign taxes. Distributions of ordinary income and capital gains, and gains from the sale of your Fund shares, are generally subject to state and local taxes. If the Fund qualifies, it may elect to pass through to you as a foreign tax credit or deduction any foreign taxes that it pays on its investments.

Non-U.S. investors. Non-U.S. investors may be subject to U.S. withholding tax at 30% or a lower treaty rate on Fund dividends of ordinary income. Non-U.S. investors may be subject to U.S. estate tax on the value of their shares. They are subject to special U.S. tax certification requirements to avoid backup withholding, claim any exemptions from withholding and claim any treaty benefits. Exemptions from U.S. withholding tax are generally provided for capital gains realized on the sale of Fund shares, capital gain dividends paid by the Fund from net long-term capital gains, short-term capital gain dividends paid by the Fund from net short-term capital gains and interest-related dividends paid by the Fund from its qualified net interest income from U.S. sources. However, notwithstanding such exemptions from U.S. withholding tax at source, any such dividends and distributions of income and capital gains will be subject to backup withholding at a rate of 24% if you fail to properly certify that you are not a U.S. person.

Other reporting and withholding requirements. Payments to a shareholder that is either a foreign financial institution or a non-financial foreign entity within the meaning of the Foreign Account Tax Compliance Act (FATCA) may be subject to a 30% withholding tax on income dividends paid by the Fund. The FATCA withholding tax generally can be avoided by such foreign entity if it provides the Fund, and in some cases, the IRS, information concerning the ownership of certain foreign financial accounts or other appropriate certifications or documentation concerning its status under FATCA. The Fund may be required to report certain shareholder account information to the IRS, non-U.S. taxing authorities or other parties to comply with FATCA.

Other tax information. This discussion of “Distributions and Taxes” is for general information only and is not tax advice. You should consult your own tax advisor regarding your particular circumstances, and about any federal, state, local and foreign tax consequences before making an investment in the Fund. Additional information about the tax consequences of investing in the Fund may be found in the SAI.

Financial Highlights

There is no financial information for the Fund because it is a new fund.

Shareholder Information

Buying and Selling Shares

Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this prospectus. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly traded companies. The Franklin Templeton ETF Trust (Trust) does not impose any minimum investment for shares of the Fund purchased on an exchange. Shares of the Fund trade under the following symbol: [____].

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges determined by your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread,” that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on the Fund’s trading volume and market liquidity, and is generally lower if the Fund has a lot of trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity.

The board of trustees has not adopted a policy of monitoring for frequent purchases and redemptions of Fund shares (frequent trading) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (market timing), because the Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions described below under Creations and Redemptions. The board of trustees has not adopted a policy of monitoring for frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The Fund’s primary listing exchange is The Nasdaq Stock Market LLC which is open for trading Monday through Friday and is closed on weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Juneteenth National Independence Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.

Section 12(d)(1) of the Investment Company Act of 1940 (1940 Act) restricts investments by investment companies in the securities of other investment companies. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules or in other exemptive relief as applicable. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1), the registered investment company must generally enter into an agreement with the Fund.

Book Entry

Shares of the Fund are held in book-entry form, which means that no share certificates are issued. The Depository Trust Company (DTC) or its nominee is the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices

The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as supply and demand, economic conditions and other factors.

Calculating NAV

The NAV of the Fund is determined by deducting the Fund’s liabilities from the total assets of the portfolio. The NAV per share is determined by dividing the total NAV of the Fund by the number of shares outstanding.

The Fund calculates the NAV per share each business day as of 1 p.m. Pacific time which normally coincides with the close of trading on the New York Stock Exchange (NYSE). The Fund does not calculate the NAV on days the NYSE is closed for trading, which include New Year’s Day, Martin Luther King Jr. Day, President’s Day, Good Friday, Memorial Day, Juneteenth National Independence Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. If the NYSE has a scheduled early close or unscheduled early close, the Fund’s share price would still be determined as of 1 p.m. Pacific time/4 p.m. Eastern time. The Fund’s NAV per share is readily available online at franklintempleton.com.

When determining its NAV, the Fund values cash and receivables at their realizable amounts, and records interest as accrued and dividends on the ex-dividend date. The Fund generally utilizes two independent pricing services to assist in determining a current market value for each security. If market quotations are readily available for portfolio securities listed on a securities exchange, the Fund values those securities at the last quoted sale price or the official closing price of the day, respectively, or, if there is no reported sale, within the range of the most recent quoted bid and ask prices. The Fund values over-the-counter portfolio securities within the range of the most recent bid and ask prices. If portfolio securities trade both in the over-the-counter market and on a stock exchange, the Fund values them according to the broadest and most representative market. Prices received by the Fund for securities may be based on institutional “round lot” sizes, but the Fund may hold smaller, “odd lot” sizes. Odd lots may trade at lower prices than round lots.

Generally, trading in corporate bonds, U.S. government securities and money market instruments is substantially completed each day at various times before 1 p.m. Pacific time. The value of these securities used in computing the NAV is determined as of such times. Occasionally, events affecting the values of these securities may occur between the times at which they are determined and 1 p.m. Pacific time that will not be reflected in the computation of the NAV. The Fund relies on third-party pricing vendors to provide evaluated prices that reflect current fair market value at 1 p.m. Pacific time.

Fair Valuation – Individual Securities

The Fund’s investment manager, in its role as valuation designee, has adopted procedures, approved by the board of trustees, to determine the fair value of individual securities and other assets for which market prices are not readily available (such as certain restricted or unlisted securities and private placements) or which may not be reliably priced (such as in the case of trade suspensions or halts, price movement limits set by certain foreign markets, and thinly traded or illiquid securities). Some methods for valuing these securities may include: fundamental analysis (earnings multiple, etc.), matrix pricing, discounts from market prices of similar securities, or discounts applied due to the nature and duration of restrictions on the disposition of the securities. The board of trustees oversees the application of fair value pricing procedures with respect to the Fund.

The application of fair value pricing procedures represents a good faith determination based upon specifically applied procedures. There can be no assurance that the Fund could obtain the fair value assigned to a security if it were able to sell the security at approximately the time at which the Fund determines its NAV per share.

Security Valuation – Pass-Through Securities, CMO, ABS, MBS

Mortgage pass-through securities (such as Ginnie Mae, Fannie Mae and Freddie Mac), other mortgage-backed securities (MBS), collateralized mortgage obligations (CMOs) and asset-backed securities (ABS) generally trade in the over-the-counter market rather than on a securities exchange. The Fund may value these portfolio securities by utilizing quotations from bond dealers, information with respect to bond and note transactions and may rely on independent pricing services. The Fund’s pricing services use valuation models or matrix pricing to determine current value. In general, they use information with respect to comparable bond and note transactions, quotations from bond dealers or by reference to other securities that are considered comparable in such characteristics as rating, interest rate, maturity date, option adjusted spread models, prepayment projections, interest rate spreads and yield curves. Matrix pricing is considered a form of fair value pricing.

Security Valuation – Corporate Debt Securities

Corporate debt securities generally trade in the over-the-counter market rather than on a securities exchange. The Fund may value these portfolio securities by utilizing quotations from bond dealers, information with respect to bond and note transactions and may rely on independent pricing services to assist in determining a current market value for each security. The Fund’s pricing services may utilize independent quotations from bond dealers and bond market activity to determine current value.

Security Valuation – Senior Secured Corporate Loans

Senior secured corporate loans with floating or variable interest rates generally trade in the over-the-counter market rather than on a securities exchange. The Fund may value these portfolio securities by utilizing quotations from loan dealers and other financial institutions, information with respect to bond and note transactions and may rely on independent pricing services to assist in determining a current market value for each security. These pricing services use independent market quotations from loan dealers or financial institutions and may incorporate valuation methodologies that incorporate multiple bond characteristics. These characteristics may include dealer quotes, issuer type, coupon, maturity, weighted average maturity, interest rate spreads and yield curves, cash flow and credit risk/quality analysis.

Trading in securities on foreign securities stock exchanges and over-the-counter markets, such as those in Europe and Asia, may be completed well before 1 p.m. Pacific time. Occasionally, events occur between the time at which trading in a foreign security is completed and 1 p.m. Pacific time that might call into question the availability (including the reliability) of the value of a foreign portfolio security held by the Fund. In accordance with procedures established and approved by the Fund’s board of trustees, the investment manager monitors for significant events following the close of trading in foreign stock markets.

In the event the investment manager identifies a significant event, the investment manager will measure price movements using a series of country specific market proxies (such as baskets of American Depositary Receipts, futures contracts and ETFs) against established trigger thresholds for each specific market proxy to assist in determining if the significant event calls into question the availability (including the reliability) of the values of foreign securities between the times at which they are determined on their primary trading market and 1 p.m. Pacific time. If such trigger thresholds are exceeded, the foreign securities may be valued using fair value procedures established and approved by the board of trustees. In certain circumstances these procedures include the use of independent pricing services. The intended effect of applying fair value pricing is to compute an NAV that accurately reflects the value of the Fund’s portfolio at the time that the NAV is calculated.

In addition, trading in foreign portfolio securities generally, or in securities markets in a particular country or countries, may not take place on every NYSE business day. Furthermore, trading takes place in various foreign markets on days that are not business days for the NYSE, and on which the Fund’s NAV is not calculated (in which case, the NAV of the Fund’s shares may change on days when shareholders will not be able to purchase or sell Fund shares). Thus, the calculation of the Fund’s NAV does not take place contemporaneously with the determination of the prices of many of the foreign portfolio securities used in the calculation. If significant events affecting the last determined values of these foreign securities occur (determined through the monitoring process described above), the securities may be valued at fair value determined in good faith in accordance with the Fund’s fair value procedures established and approved by the board of trustees.

Creations and Redemptions

Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 50,000 shares or multiples thereof. An “Authorized Participant” is a member or participant of a clearing agency registered with the SEC, which has a written agreement with the Fund or one of its service providers (AP Agreement) that allows such member or participant to place orders for the purchase and redemption of Creation Units. All orders for the creation or redemption of Creation Units for the Fund must be placed by or through an Authorized Participant that has entered into an AP Agreement with Distributors, an affiliate of the investment manager and sub-advisor.

A creation transaction, which is subject to acceptance by Distributors or its agents, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities, assets or other positions and/or an amount of cash (which may include cash in lieu of certain securities, assets or other positions) in exchange for a specified number of Creation Units.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities, assets or other positions and/or cash (which may include cash in lieu of certain securities, assets or other positions).

The prices at which creations and redemptions occur are based on the next calculation of NAV after a creation or redemption order is received in an acceptable form under the AP Agreement.

Creation and redemption baskets may differ and the Fund will accept “custom baskets.” More information regarding custom baskets is contained in the Fund’s SAI. As a result of any system failure or other interruption, creation or redemption orders either may not be executed according to the Fund’s instructions or may not be executed at all, or the Fund may not be able to place or change such orders. Information about the procedures regarding creations and redemptions of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(a)(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(a)(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Premium/Discount Information

Information regarding how often the shares of the Fund traded on The Nasdaq Stock Market LLC at a price above (at a premium) or below (at a discount) the NAV of the Fund for the most recently completed calendar year, and the most recently completed calendar quarters since that year, when available, can be found at https://www.franklintempleton.com/investor/investments-and-solutions/investment-options/etfs/.

Delivery of Shareholder Documents - Householding

You will receive the Fund’s financial reports every six months as well as an annual updated prospectus. Householding for the Fund is available through certain broker-dealers. Householding is a process in which related shareholders in a household will be sent only one copy of the financial reports and prospectus. You may contact your broker-dealer to enroll in householding. Once enrolled, this process will continue indefinitely unless you instruct your broker-dealer otherwise. If you prefer not to have these documents householded, please contact your broker-dealer. At any time you may view current prospectuses and financial reports on our website.

Distribution

Distributors or its agents distribute Creation Units for the Fund on an agency basis. Distributors does not maintain a secondary market in shares of the Fund. Distributors is an affiliate of Advisers.

Distribution and service (12b-1) fees 

The board of trustees has adopted a distribution plan, sometimes known as a Rule 12b-1 plan, that allows the Fund to pay distribution fees of up to 0.25% per year, to those who sell and distribute Fund shares and provide other services to shareholders. However, the board of trustees has determined not to authorize payment of a Rule 12b-1 plan fee at this time.

Because these fees are paid out of the Fund’s assets on an ongoing basis, to the extent that a fee is authorized, over time these fees will increase the cost of your investment and may cost you more than paying other types of sales charges.
