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 (Distributors). 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 is available on the Fund’s website at https://www.franklintempleton.com/investor/investments-and-solutions/investment-options/etfs/.

FUND SUMMARY

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as a 401(k) plan or an individual retirement account, in which case your distributions would generally be taxed when withdrawn from the tax-advantaged account.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.

Investment Goal

The Fund's investment goal is to seek total return. 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

Under normal market conditions, the Fund invests at least 80% of its net assets in U.S. fixed income securities, and in derivatives and other instruments that have economic characteristics and provide investment exposure similar to U.S. fixed income securities. U.S. fixed income securities include debt securities issued or guaranteed by the U.S. government, its agencies or instrumentalities and political sub-divisions (including inflation index linked securities and municipal bonds); U.S. corporate debt securities, including debentures, bonds (including zero coupon bonds), bankers acceptances (issued by industrial, utility, finance, commercial banking or bank holding company organizations), convertible and non-convertible notes, commercial paper, certificates of deposits, and freely transferable promissory notes; mortgage-backed securities; and asset-backed securities. U.S. fixed income securities also include securities included in the Bloomberg U.S. Aggregate Index. Shareholders will be given at least 60 days’ advance notice of any change to the Fund’s 80% policy.

For purposes of determining whether an instrument is economically tied to the U.S., the Fund uses the country assigned to a security by Bloomberg or another unaffiliated third-party data provider. The data providers use various criteria to determine the country to which a security is economically tied. Examples include the following: (1) the country under which the issuer is organized; (2) the location of the issuer’s principal place of business or principal office; (3) where the issuer’s securities are listed or traded principally on an exchange or over-the-counter market; and (4) where the issuer conducts the predominant part of its business activities or derives a significant portion (e.g., at least 50%) of its revenues or profits.

The Fund invests in U.S. dollar denominated investment grade fixed income securities. Investment grade fixed income securities are securities that are rated at the time of purchase in the top four ratings categories by one or more independent rating organizations such as S&P^® Global Ratings (S&P^®) (rated BBB- or better) or Moody’s Investors Service (Moody’s) (rated Baa3 or higher) or, if unrated, are determined to be of comparable quality by the sub-advisor. A downgrade of a particular security below one of the top four ratings categories will not automatically

BRANDYWINEGLOBAL – U.S. FIXED INCOME ETF
FUND DETAILS

cause the Fund to sell the security. The Fund may invest in variable and floating rate securities. The Fund may also invest a portion of its assets in cash or cash equivalents.

The sub-advisor intends to take an active approach to duration management and does not track the duration of the Fund’s benchmark index. The Fund may invest in securities of any maturity or duration. Under normal conditions, the portfolio managers typically seek to maintain a dollar-weighted average effective duration for the Fund’s portfolio, including derivatives, of 1 to 10 years. The dollar-weighted average effective duration of the Fund’s portfolio may, however, exceed this range materially from time to time depending on the sub-advisor’s valuation analysis and macro-economic outlook. For example, in situations where elevated interest rates have a detrimental effect on consumer or business conditions, resulting in a slowdown in economic activity, the sub-advisor may materially increase duration with the objective of profiting from potential changes in central bank policies, such as a reduction in interest rates, aimed at revitalizing economic activity. In comparison to maturity (which is the date on which a debt instrument ceases and the issuer is obligated to repay the principal amount), duration is a measure of the expected price volatility of a debt instrument as a result of changes in market rates of interest, based on the weighted average timing of the instrument’s expected principal and interest payments and other factors. Duration differs from maturity in that it considers a security’s yield, coupon payments, principal payments, call features and coupon adjustments in addition to the amount of time until the security finally matures. As the value of a security changes over time, so will its duration. In general, a portfolio of securities with a lower duration can be expected to be less sensitive to interest rate changes than a portfolio with a higher duration. Duration measures a fixed income security's price sensitivity to interest rates by indicating the approximate change in a fixed income security's price if interest rates move up or down in 1% increments. For example, when the level of interest rates increases by 1%, the price of a fixed income security or a portfolio of fixed income securities having a positive duration of five years generally will decrease by approximately 5% and the price of a fixed income security or a portfolio of fixed income securities having a negative duration of five years generally will increase by approximately 5%. Conversely when the level of interest rates decreases by 1%, the price of a fixed income security or a portfolio of fixed income securities having a positive duration of five years generally will increase by approximately 5% and the price of a fixed income security or a portfolio of fixed income securities having a negative duration of five years generally will decrease by approximately 5%.

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. The Fund’s investments in

BRANDYWINEGLOBAL – U.S. FIXED INCOME ETF
FUND DETAILS

mortgage-backed securities include securities that are issued or guaranteed by the U.S. government, its agencies or instrumentalities, which include mortgage pass-through securities representing interests in “pools” of mortgage loans issued or guaranteed by the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), and the Federal Home Loan Mortgage Corporation (Freddie Mac). Securities issued by different government agencies or instrumentalities have different levels of credit support. The Fund may also invest in other types of mortgage securities that may be issued or guaranteed by private issuers including commercial mortgage-backed securities (CMBS) and collateralized mortgage obligations (CMOs).

The Fund may purchase or sell mortgage-backed securities on a delayed delivery or forward commitment basis through the “to-be-announced” (TBA) market. With TBA transactions, the particular securities to be delivered are not identified at the trade date but the delivered securities must meet specified terms and standards (such as yield, duration, and credit quality). The Fund may also invest in restricted securities including Rule 144A securities.

An asset-backed security is a security backed by loans, leases, and other receivables. The Fund may invest in collateralized loan obligations (CLOs). CLOs are interests in a trust typically collateralized substantially by a pool of loans, which may include, among others, domestic and foreign senior secured loans, senior unsecured loans, and subordinate corporate loans made to domestic and foreign borrowers, including loans that may be rated below investment grade or equivalent unrated loans.

For purposes of pursuing its investment goal, the Fund may enter into various interest rate and credit-related derivatives, principally U.S. Treasury futures and credit default swaps (including credit default index swaps). The use of these derivative transactions may allow the Fund to obtain exposures to select interest rates, durations or credit risks. These derivatives may be used to enhance Fund returns, increase liquidity, gain exposure to certain instruments or markets in a more efficient or less expensive way and/or hedge risks associated with its other portfolio investments. Derivatives that have economic characteristics and provide investment exposure similar to U.S. fixed income securities will be counted towards the Fund’s 80% investment policy.

A futures contract is a standard binding agreement to buy or sell a specified quantity of an underlying instrument or asset at a specified price at a specified later date that trades on an exchange. A “sale” of a futures contract means the acquisition of a contractual obligation to deliver the underlying instrument specified in the contract at a specified price on a specified date. A “purchase” of a futures contract means the acquisition of a contractual obligation to purchase the underlying instrument specified in the contract at a specified price on a specified date. The purchase or sale of a futures contract will allow the Fund to increase or

BRANDYWINEGLOBAL – U.S. FIXED INCOME ETF
FUND DETAILS

decrease its exposure to the underlying instrument or asset. Although many futures contracts used by the Fund allow for a cash payment of the net gain or loss on the contract at maturity in lieu of delivery of the underlying instrument, some require the actual delivery or acquisition of the underlying instrument.

Swap agreements, such as credit default swaps, are contracts between the Fund and another party (the swap counterparty) involving the exchange of payments on specified terms over periods ranging from a few days to multiple years. A swap agreement may be negotiated bilaterally and traded over-the-counter (OTC) between two parties (for an uncleared swap) or, in some instances, must be transacted through a futures commission merchant (FCM) and cleared through a clearinghouse that serves as a central counterparty (for a cleared swap). In a basic swap transaction, the Fund agrees with the swap counterparty to exchange the returns (or differentials in rates of return) and/or cash flows earned or realized on a particular “notional amount” of underlying reference assets. The notional amount is the set amount selected by the parties as the basis on which to calculate the obligations that they have agreed to exchange. The parties typically do not actually exchange the notional amount. Instead, they agree to exchange the returns that would be earned or realized if the notional amount were invested in given instruments or at given interest rates.

For credit default swaps, the “buyer” of the credit default swap agreement is obligated to pay the “seller” a periodic stream of payments over the term of the agreement in return for a payment by the seller that is contingent upon the occurrence of a credit event with respect to an underlying reference debt obligation. The buyer of the credit default swap is purchasing the obligation of its counterparty to offset losses the buyer could experience if there was such a credit event. Generally, a credit event means bankruptcy, failure to timely pay interest or principal, obligation acceleration or default, or repudiation or restructuring of the reference debt obligation. The contingent payment by the seller generally is either the face amount of the reference debt obligation in exchange for the physical delivery of the reference debt obligation or a cash payment equal to the decrease in market value of the reference debt obligation following the occurrence of the credit event.

The portfolio managers consider various factors, such as availability of securities that the portfolio manager seeks to gain access to and the cost to tactically trade specific positions, in deciding whether to use a particular derivative instrument or strategy. There may be instances when it is more efficient and cost effective to express a view in the portfolio through the use of derivatives as opposed to investing directly in the fixed income security.

The portfolio managers’ investment process is top-down, macro-economic driven and value oriented. Their buy discipline is highlighted by patience and conviction. The portfolio managers develop a viewpoint on the business cycle in conjunction

BRANDYWINEGLOBAL – U.S. FIXED INCOME ETF
FUND DETAILS

with a value-based analysis of U.S. dollar-denominated, investment-grade fixed income securities to determine the Fund’s strategy duration, sector and quality exposures over time. Security selection is determined through analysis of both top-down, macroeconomic conditions as well as bottom-up, fundamental analysis within the context of their value-oriented framework.

In analyzing macroeconomic conditions, the portfolio managers take into account things such as geopolitical and demographic factors that might impact the overall economy. This framework informs the broad investment themes of the portfolio and helps the portfolio managers determine duration and sector allocations. Bottom-up, fundamental analysis is utilized to help identify specific securities or issues that might be invested in or should be avoided. The portfolio managers focus their investments on a limited number of securities that they believe represent attractive value, rather than invest the portfolio across a large spectrum of securities in attempt to replicate an index-like distribution. If they do not find value in a particular sector, industry or security, they will not invest in it. The portfolio managers utilize both qualitative and quantitative criteria (including proprietary quantitative models) as part of the portfolio construction process, including in determining that an investment represents an attractive value. An investment offers an attractive value if the portfolio managers, through their analysis, have determined that the investment is mispriced and trading below what current or expected economic conditions warrant. Quantitative models are proprietary systems that rely on mathematical computations to identify investment opportunities.

When evaluating mortgage-backed, asset-backed and restricted securities, the portfolio managers take into account factors such as the securities’ vintage, credit quality, underlying assets that back these securities, geographic exposures, prepayment and default probabilities, and specific details embedded within the securities’ offering documents. This is coupled with the portfolio managers’ macroeconomic analysis that informs their outlook on factors such as interest rates and the political and regulatory environment that may impact the trading levels for these securities.

The portfolio managers sell fixed income securities or sectors when they no longer meet their value criteria. This could be due to the impact of the business cycle or fundamental changes affecting yield, spread or price. For example, they typically sell corporate bonds and mortgage-backed securities when spreads narrow significantly or when changing fundamentals introduce risks outweighing potential rewards. In some cases, they may modify the characteristics or risk profile of a sector instead of completely eliminating exposure, such as by shortening duration.

Alongside traditional financial and economic analyses, the sub-advisor typically assesses the potential impacts of material environmental, social and governance (ESG) factors on an issuer to determine whether, in the sub-advisor’s view, an issuer’s ESG practices present a financial opportunity or risk for an investment.

BRANDYWINEGLOBAL – U.S. FIXED INCOME ETF
FUND DETAILS

Consideration of ESG factors and risks is only one potential input in the sub-advisor’s assessment of eligible investments and, as with any inputs considered by the sub-advisor, may not be a determinative factor in the sub-advisor’s final decision on whether to purchase (or sell) a security. In addition, where ESG factors are considered, the weight given to ESG factors may vary across types of investments, industries, regions and issuers and ESG factors and weights considered may change over time. The sub-advisor may not assess every investment for ESG factors and, when it does, not every ESG factor may be identified or evaluated. Investments in derivatives and cash management instruments will not be assessed for ESG factors.

The Fund anticipates engaging in active and frequent trading to achieve its 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. Furthermore, events involving limited liquidity, defaults, non-performance or other adverse developments that affect one industry, such as the financial services industry, or concerns or rumors about any events of these kinds, have in the past and may in the future lead to market-wide liquidity problems, may spread to other industries, and could negatively affect the value and liquidity of the Fund’s investments. 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 and its subsequent variants, has resulted in market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. The long-term impact on economies, markets, industries and individual issuers are not known. Some sectors of the economy and individual issuers have experienced or may experience

BRANDYWINEGLOBAL – U.S. FIXED INCOME ETF
FUND DETAILS

particularly large losses. Periods of extreme volatility in the financial markets; reduced liquidity of many instruments; and disruptions to supply chains, consumer demand and employee availability, may continue for some time. The U.S. government and the Federal Reserve, as well as certain foreign governments and central banks, have taken extraordinary actions to support local and global economies and the financial markets in response to the COVID-19 pandemic. This and other government intervention into the economy and financial markets may not work as intended, and have resulted in a large expansion of government deficits and debt, the long term consequences of which are not known. In addition, the COVID-19 pandemic, and measures taken to mitigate its effects, could result in disruptions to the services provided to the Fund by its service providers.

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.

Credit The Fund could lose money on a debt security if the issuer or borrower is unable or fails to meet its obligations, including failing to make interest payments and/or to repay principal when due. Changes in an issuer's financial strength, the market's perception of the issuer's financial strength or an issuer's or security's credit rating, which reflects a third party's assessment of the credit risk presented by a particular issuer or security, may affect debt securities' values. The Fund may incur substantial losses on debt securities that are inaccurately perceived to present a different amount of credit risk by the market, the sub-advisor or the rating agencies than such securities actually do.

Mortgage 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 has guaranteed or provided credit support for 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

BRANDYWINEGLOBAL – U.S. FIXED INCOME ETF
FUND DETAILS

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. Although the U.S. government has recently 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. Any downgrade of the credit rating of the securities issued by the U.S. government may result in a downgrade of securities issued by its agencies or instrumentalities, including government-sponsored entities.

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.

BRANDYWINEGLOBAL – U.S. FIXED INCOME ETF
FUND DETAILS

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 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, index 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 and the Fund’s liquidity may be impaired. 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

BRANDYWINEGLOBAL – U.S. FIXED INCOME ETF
FUND DETAILS

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.

Credit default swap contracts involve heightened risks and may result in losses to the Fund. If the Fund buys a credit default swap, it will be subject to the risk that the credit default swap may expire worthless, as the credit default swap would only generate income in the event of a default on the underlying debt security or other specified event. As a buyer, the Fund would also be subject to credit risk relating to the seller’s payment of its obligations in the event of a default (or similar event). If the Fund sells a credit default swap, it will be exposed to the credit risk of the issuer of the obligation to which the credit default swap relates. As a seller, the Fund would also be subject to leverage risk, because it would be liable for the full notional amount of the swap in the event of a default (or similar event).

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.

BRANDYWINEGLOBAL – U.S. FIXED INCOME ETF
FUND DETAILS

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.

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.

Liquidity Liquidity risk exists when the markets for particular securities or types of securities or other investments are or become relatively illiquid so that the Fund is unable, or it becomes more difficult for the Fund, to sell the security or other investment at the price at which the Fund has valued the security. Illiquidity may result from political, economic or issuer specific events; supply/demand imbalances; changes in a specific market’s size or structure, including the number of participants; or overall market disruptions. Securities or other investments with reduced liquidity or that become illiquid may involve greater risk than securities with more liquid markets. Market prices or quotations for illiquid securities may be volatile, and there may be large spreads between bid and ask prices. Reduced liquidity may have an adverse impact on market price and the Fund's ability to sell particular securities when necessary to meet the Fund's liquidity needs, which may arise or increase in response to a specific economic event or because the sub-advisor wishes to purchase particular investments or believes that a higher level of liquidity would be advantageous. An investment may become illiquid if the Fund and its affiliates receive material non-public information about the issuer or the investment. To the extent that the Fund and its affiliates hold a significant portion of an issuer's outstanding securities, the Fund may be subject to greater liquidity risk than if the issuer's securities were more widely held.

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

FUND DETAILS

reset to market rates. You could lose money if you sell your shares of the Fund before these rates reset.

Collateralized Loan Obligations (CLOs) The risks of an investment in a CLO depend largely on the type of collateral held by the special purpose entity (SPE) and the tranche of the CLO in which the Fund invests. Investment risk may also be affected by the performance of a CLO’s collateral manager (the entity responsible for selecting and managing the pool of collateral securities held by the SPE trust), especially during a period of market volatility. CLOs may be deemed to be illiquid and subject to the Fund’s restrictions on investments in illiquid investments. The Fund’s investment in CLOs will not receive the same investor protection as an investment in registered securities.

In addition, prices of CLO tranches can decline considerably. In addition to the normal risks associated with debt securities and loans (e.g., interest rate risk, credit risk and default risk), CLOs carry additional risks including, but not limited to: (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments; (ii) the quality of the collateral may decline in value or quality or go into default or be downgraded; (iii) the Fund may invest in tranches of a CLO that are subordinate to other classes; and (iv) the complex structure of the security may not be fully understood at the time of investment and may produce disputes with the issuer, difficulty in valuing the security or unexpected investment results.

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.

Models

The models that may be used by the sub-advisor as part of the Fund’s portfolio construction process to identify investment opportunities have been tested on historical price data. These models are based on the assumption that price movements in most markets display similar patterns. There is the risk that market behavior will change and that the patterns upon which the forecasts in the models are based will weaken or disappear, which would reduce the ability of the models to generate an excess return. Further, as market dynamics shift over time, a previously highly successful model may become outdated, perhaps without the sub-advisor recognizing that fact before substantial losses are incurred. Successful operation of a model is also reliant upon the information technology systems of the sub-advisor and its ability to ensure those systems remain operational and that

BRANDYWINEGLOBAL – U.S. FIXED INCOME ETF
FUND DETAILS

appropriate disaster recovery procedures are in place. There can be no assurance that the sub-advisor will be successful in maintaining effective and operational models and the related hardware and software systems.

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.

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.

Market Trading

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.

BRANDYWINEGLOBAL – U.S. FIXED INCOME ETF
FUND DETAILS

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.

BRANDYWINEGLOBAL – U.S. FIXED INCOME ETF
FUND DETAILS

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.

BRANDYWINEGLOBAL – U.S. FIXED INCOME ETF
FUND DETAILS

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.

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.

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

BRANDYWINEGLOBAL – U.S. FIXED INCOME ETF
FUND DETAILS

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 sub-advisor, and their service providers are subject to the risk of cyber incidents occurring from time to time.

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, 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

BRANDYWINEGLOBAL – U.S. FIXED INCOME ETF
FUND DETAILS

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, 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.

BRANDYWINEGLOBAL – U.S. FIXED INCOME ETF
FUND DETAILS

Fund’s assets and Advisers pays Brandywine Global for its services . 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 0.39% of the average daily net assets of the Fund.

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

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 sub-advisory agreements.

The use of the Manager of Managers Structure with respect to the Fund is subject to certain conditions that are set forth in SEC exemptive relief and no-action letter guidance issued by the SEC staff. Under the Manager of Managers Structure, the investment manager has the ultimate responsibility, subject to oversight by the Fund’s board of trustees, to oversee sub-advisors and recommend their hiring, termination and replacement. The investment manager will also, subject to the review and oversight of the Fund’s board of trustees: set the Fund’s overall investment strategy; evaluate, select and recommend sub-advisors to manage all or a portion of the Fund’s assets; and implement procedures reasonably designed to ensure that each sub-advisor complies with the Fund’s investment goal, policies and restrictions. Subject to review and oversight by the Fund’s board of trustees, the investment manager will allocate and, when appropriate, reallocate the Fund’s

BRANDYWINEGLOBAL – U.S. FIXED INCOME ETF
FUND DETAILS

assets among sub-advisors and monitor and evaluate the sub-advisors’ performance.

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

BRANDYWINEGLOBAL – U.S. FIXED INCOME ETF
FUND DETAILS

certain holding period requirements are met. 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

BRANDYWINEGLOBAL – U.S. FIXED INCOME ETF
FUND DETAILS

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

BRANDYWINEGLOBAL – U.S. FIXED INCOME ETF
FUND DETAILS

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.

SHAREHOLDER INFORMATION

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: USFI

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.

SHAREHOLDER INFORMATION

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

SHAREHOLDER INFORMATION

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

SHAREHOLDER INFORMATION

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.

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.

SHAREHOLDER INFORMATION

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/.

SHAREHOLDER INFORMATION

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.
