FRANKLIN LIBERTYQ EMERGING MARKETS ETF

Performance Summary as of March 31, 2022

Total return reflects reinvestment of the Fund’s dividends and capital gain distributions, if any, and any unrealized gains or losses. Total returns do not include brokerage commissions that may be payable on secondary market transactions. The performance table and graph do not reflect any taxes that a shareholder would pay on Fund dividends, capital gain distributions, if any, or any realized gains on the sale of Fund shares.

Net asset value or “NAV” is the value of one share of a fund as calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market return (Market Price) is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of a fund are listed for trading, as of the time that such fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary trading (6/3/16), the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested at Market Price and NAV.

Your dividend income will vary depending on dividends or interest paid by securities in the Fund’s portfolio, adjusted for operating expenses. Capital gain distributions are net profits realized from the sale of portfolio securities.

Performance as of 3/31/22¹

Total Annual Operating Expenses⁷

All investments involve risks, including possible loss of principal. Stock prices fluctuate, sometimes rapidly and dramatically, due to factors affecting individual companies, particular industries or sectors, or general market conditions. Special risks are associated with foreign investing, including currency fluctuations, economic instability and political developments. Investments in developing markets involve heightened risks related to the same factors, in addition to those associated with these markets’ smaller size, lesser liquidity and lack of established legal, political, business and social frameworks to support securities markets. The Fund is designed for the aggressive portion of a well-diversified portfolio. There can be no assurance that the Fund’s multi-factor stock selection process will enhance performance. Exposure to such investment factors may detract from performance in some market environments, perhaps for extended periods. Performance of the Fund may vary significantly from the performance of an index, as a result of transaction costs, expenses and other factors. Events such as the spread of deadly diseases, disasters, and financial, political or social disruptions, may heighten risks and adversely affect performance. The Fund’s prospectus also includes a description of the main investment risks.

Russia’s military invasion of Ukraine in February 2022, the resulting responses by the United States and other countries, and the potential for wider conflict could increase volatility and uncertainty in the financial markets and adversely affect regional and global economies. The United States and other countries have imposed broad-ranging economic sanctions on Russia and certain Russian individuals, banking entities and corporations as a response to its invasion of Ukraine. The United States and other countries have also imposed economic sanctions on Belarus and may impose sanctions on other countries that support Russia’s military invasion. These sanctions, as well as any other economic consequences related to the invasion, such as additional sanctions, boycotts or changes in consumer or purchaser preferences or cyberattacks on governments, companies or individuals, may further decrease the value and liquidity of certain Russian securities and securities of issuers in other countries that are subject to economic sanctions related to the invasion. To the extent that the Fund has exposure to Russian investments or investments in countries affected by the invasion, the Fund’s the ability to price, buy, sell, receive or deliver such investments may be impaired. The Fund could determine at any time that certain of the most affected securities have zero value. In addition, any exposure that the Fund may have to counterparties in Russia or in countries affected by the invasion could negatively impact the Fund’s portfolio. The extent and duration of Russia’s military actions and the repercussions of such actions (including any retaliatory actions or countermeasures that may be taken by those subject to sanctions) are impossible to predict, but could result in significant market disruptions, including in the oil and natural gas markets, and may negatively affect global supply chains, inflation and global growth. These and any related events could significantly impact the Fund’s performance and the value of an investment in the Fund, even beyond any direct exposure the Fund may have to Russian issuers or issuers in other countries affected by the invasion.

ETFs trade like stocks, fluctuate in market value and may trade at prices above or below their net asset value. Brokerage commissions and ETF expenses will reduce returns.

1. Effective December 1, 2017, the Fund adopted a unified fee structure whereby Management has agreed to reimburse the Fund’s acquired fund fees and expenses (if any) and pay all of the ordinary operating expenses of the Fund, including custody, transfer agency, and Trustee fees and expenses, among others, but excluding: (i) payments under the Fund’s Rule 12b-1 plan (if any); (ii) brokerage expenses (including any costs incidental to transactions in portfolio securities or instruments); (iii) taxes; (iv) interest (including borrowing costs and dividend expenses on securities sold short and overdraft charges); (v) litigation expenses (including litigation to which the Trust or a Fund may be a party and indemnification of the Trustees and officers with respect thereto); and (vi) other non-routine or extraordinary expenses.

2. Total return calculations represent the cumulative and average annual changes in value of an investment over the periods indicated. Return for less than one year, if any, has not been annualized.

Your Fund’s Expenses

As a Fund shareholder, you can incur two types of costs: (1) transaction costs, including brokerage commissions on purchases and sales of Fund shares; and (2) ongoing Fund costs, including management fees and other Fund expenses. All funds have ongoing costs, sometimes referred to as operating expenses. The table below shows ongoing costs of investing in the Fund and can help you understand these costs and compare them with those of other funds. The table assumes a $1,000 investment held for the six months indicated.

Actual Fund Expenses

The table below provides information about actual account values and actual expenses in the columns under the heading “Actual.” In these columns the Fund’s actual return, which includes the effect of Fund expenses, is used to calculate the “Ending Account Value.” You can estimate the expenses you paid during the period by following these steps (of course, your account value and expenses will differ from those in this illustration): Divide your account value by $1,000 (if your account had an $8,600 value, then $8,600 ÷ $1,000 = 8.6). Then multiply the result by the number in the row under the headings “Actual” and “Expenses Paid During Period” (if Actual Expenses Paid During Period were $7.50, then 8.6 x $7.50 = $64.50). In this illustration, the actual expenses paid this period are $64.50.

Hypothetical Example for Comparison with Other Funds

Under the heading “Hypothetical” in the table, information is provided about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. This information may not be used to estimate the actual ending account balance or expenses you paid for the period, but it can help you compare ongoing costs of investing in the Fund with those of other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds.

Please note that expenses shown in the table are meant to highlight ongoing costs and do not reflect any transactional costs. Therefore, information under the heading “Hypothetical” is useful in comparing ongoing costs only, and will not help you compare total costs of owning different funds. In addition, if transactional costs were included, your total costs would have been higher.

1. Expenses are equal to the annualized expense ratio for the six-month period as indicated above—in the far right column—multiplied by the simple average account value over the period indicated, and then multiplied by 182/365 to reflect the one-half year period.

2. Reflects expenses after fee waivers and expense reimbursements.

Total Annual Operating Expenses⁶

All investments involve risks, including possible loss of principal. Stock prices fluctuate, sometimes rapidly and dramatically, due to factors affecting individual companies, particular industries or sectors, or general market conditions. Special risks are associated with foreign investing, including currency fluctuations, economic instability and political developments; investments in emerging markets involve heightened risks related to the same factors. To the extent the Fund focuses on particular countries, regions, industries, sectors or types of investment from time to time, it may be subject to greater risks of adverse developments in such areas of focus than a fund that invests in a wider variety of countries, regions, industries, sectors or investments. Companies that have historically paid regular dividends to shareholders may decrease or eliminate dividend payments in the future. A decrease in dividend payments by an issuer may result in a decrease in the value of the issuer’s stock and less available income for the Fund. There can be no assurance that the Fund’s quality factor stock selection process and dividend screens of the Underlying Index will enhance performance. Exposure to investment factors and the use of dividend screens may detract from performance in some market environments, perhaps for extended periods. Performance of the Fund may vary significantly from the performance of an index, as a result of transaction costs, expenses and other factors. Events such as the spread of deadly diseases, disasters, and financial, political or social disruptions, may heighten risks and adversely affect performance.

To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds.

Please note that expenses shown in the table are meant to highlight ongoing costs and do not reflect any transactional costs. Therefore, information under the heading “Hypothetical” is useful in comparing ongoing costs only, and will not help you compare total costs of owning different funds. In addition, if transactional costs were included, your total costs would have been higher.

1. Expenses are equal to the annualized expense ratio for the six-month period as indicated above—in the far right column—multiplied by the simple average account value over the period indicated, and then multiplied by 182/365 to reflect the one-half year period.

Performance Summary as of March 31, 2022

Total return reflects reinvestment of the Fund’s dividends and capital gain distributions, if any, and any unrealized gains or losses. Total returns do not include brokerage commissions that may be payable on secondary market transactions. The performance table and graph do not reflect any taxes that a shareholder would pay on Fund dividends, capital gain distributions, if any, or any realized gains on the sale of Fund shares.

Net asset value or “NAV” is the value of one share of a fund as calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market return (Market Price) is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of a fund are listed for trading, as of the time that such fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary trading (6/3/16), the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested at Market Price and NAV.

Your dividend income will vary depending on dividends or interest paid by securities in the Fund’s portfolio, adjusted for operating expenses. Capital gain distributions are net profits realized from the sale of portfolio securities.

Total Annual Operating Expenses⁷

All investments involve risks, including possible loss of principal. Stock prices fluctuate, sometimes rapidly and dramatically, due to factors affecting individual companies, particular industries or sectors, or general market conditions. Special risks are associated with foreign investing, including currency fluctuations, economic instability and political developments; investments in emerging markets involve heightened risks related to the same factors. To the extent the Fund focuses on particular countries, regions, industries, sectors or types of investment from time to time, it may be subject to greater risks of adverse developments in such areas of focus than a fund that invests in a wider variety of countries, regions, industries, sectors or investments. The Fund will attempt to hedge the currency exposure of non-U.S. dollar denominated securities held in its portfolio by investing in foreign currency forward contracts. Foreign currency forward contracts do not eliminate movements in the value of non-U.S. currencies and securities but rather allow the Fund to establish a fixed rate of exchange for a future point in time. Investments in derivatives involve costs and create economic leverage, which may result in significant volatility and cause the Fund to participate in losses (as well as gains) that significantly exceed the Fund’s initial investment. Currency management strategies could result in losses to the Fund if currencies do not perform as the investment manager expects. There can be no assurance that the Fund’s multi-factor stock selection process will enhance performance. Exposure to such investment factors may detract from performance in some market environments, perhaps for extended periods. Performance of the Fund may vary significantly from the performance of an index, as a result of transaction costs, expenses and other factors. Events such as the spread of deadly diseases, disasters, and financial, political or social disruptions, may heighten risks and adversely affect performance. The Fund’s prospectus also includes a description of the main investment risks.

Russia’s military invasion of Ukraine in February 2022, the resulting responses by the United States and other countries, and the potential for wider conflict could increase volatility and uncertainty in the financial markets and adversely affect regional and global economies. The United States and other countries have imposed broad-ranging economic sanctions on Russia and certain Russian individuals, banking entities and corporations as a response to its invasion of Ukraine. The United States and other countries have also imposed economic sanctions on Belarus and may impose sanctions on other countries that support Russia’s military invasion. These sanctions, as well as any other economic consequences related to the invasion, such as additional sanctions, boycotts or changes in consumer or purchaser preferences or cyberattacks on governments, companies or individuals, may further decrease the value and liquidity of certain Russian securities and securities of issuers in other countries that are subject to economic sanctions related to the invasion.

ETFs trade like stocks, fluctuate in market value and may trade at prices above or below their net asset value. Brokerage commissions and ETF expenses will reduce returns.

1. Effective December 1, 2017, the Fund adopted a unified fee structure whereby Management has agreed to reimburse the Fund’s acquired fund fees and expenses (if any) and pay all of the ordinary operating expenses of the Fund, including custody, transfer agency, and Trustee fees and expenses, among others, but excluding: (i) payments under the Fund’s Rule 12b-1 plan (if any); (ii) brokerage expenses (including any costs incidental to transactions in portfolio securities or instruments); (iii) taxes; (iv) interest (including borrowing costs and dividend expenses on securities sold short and overdraft charges); (v) litigation expenses (including litigation to which the Trust or a Fund may be a party and indemnification of the Trustees and officers with respect thereto); and (vi) other non-routine or extraordinary expenses.

Your Fund’s Expenses

As a Fund shareholder, you can incur two types of costs: (1) transaction costs, including brokerage commissions on purchases and sales of Fund shares; and (2) ongoing Fund costs, including management fees and other Fund expenses. All funds have ongoing costs, sometimes referred to as operating expenses. The table below shows ongoing costs of investing in the Fund and can help you understand these costs and compare them with those of other funds. The table assumes a $1,000 investment held for the six months indicated.

Actual Fund Expenses

The table below provides information about actual account values and actual expenses in the columns under the heading “Actual.” In these columns the Fund’s actual return, which includes the effect of Fund expenses, is used to calculate the “Ending Account Value.” You can estimate the expenses you paid during the period by following these steps (of course, your account value and expenses will differ from those in this illustration): Divide your account value by $1,000 (if your account had an $8,600 value, then $8,600 ÷ $1,000 = 8.6). Then multiply the result by the number in the row under the headings “Actual” and “Expenses Paid During Period” (if Actual Expenses Paid During Period were $7.50, then 8.6 x $7.50 = $64.50). In this illustration, the actual expenses paid this period are $64.50.

Hypothetical Example for Comparison with Other Funds

Under the heading “Hypothetical” in the table, information is provided about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. This information may not be used to estimate the actual ending account balance or expenses you paid for the period, but it can help you compare ongoing costs of investing in the Fund with those of other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds.

All investments involve risks, including possible loss of principal. Stock prices fluctuate, sometimes rapidly and dramatically, due to factors affecting individual companies, particular industries or sectors, or general market conditions. To the extent the Fund concentrates in a specific industry or group of industries, the Fund will carry much greater risks of adverse developments and price movements in such industries than a fund that invests in a wider variety of industries; there is also the risk that the Fund will perform poorly during a slump in demand for securities of companies in such industries. There can be no assurance that the Fund’s multi-factor stock selection process will enhance performance.

Your Fund’s Expenses

As a Fund shareholder, you can incur two types of costs: (1) transaction costs, including brokerage commissions on purchases and sales of Fund shares; and (2) ongoing Fund costs, including management fees and other Fund expenses. All funds have ongoing costs, sometimes referred to as operating expenses. The table below shows ongoing costs of investing in the Fund and can help you understand these costs and compare them with those of other funds. The table assumes a $1,000 investment held for the six months indicated.

Actual Fund Expenses

The table below provides information about actual account values and actual expenses in the columns under the heading “Actual.” In these columns the Fund’s actual return, which includes the effect of Fund expenses, is used to calculate the “Ending Account Value.” You can estimate the expenses you paid during the period by following these steps (of course, your account value and expenses will differ from those in this illustration): Divide your account value by $1,000 (if your account had an $8,600 value, then $8,600 ÷ $1,000 = 8.6). Then multiply the result by the number in the row under the headings “Actual” and “Expenses Paid During Period” (if Actual Expenses Paid During Period were $7.50, then 8.6 x $7.50 = $64.50). In this illustration, the actual expenses paid this period are $64.50.

Hypothetical Example for Comparison with Other Funds

Under the heading “Hypothetical” in the table, information is provided about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. This information may not be used to estimate the actual ending account balance or expenses you paid for the period, but it can help you compare ongoing costs of investing in the Fund with those of other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds.

Please note that expenses shown in the table are meant to highlight ongoing costs and do not reflect any transactional costs. Therefore, information under the heading “Hypothetical” is useful in comparing ongoing costs only, and will not help you compare total costs of owning different funds. In addition, if transactional costs were included, your total costs would have been higher.

Total returns do not include brokerage commissions that may be payable on secondary market transactions. The performance table and graph do not reflect any taxes that a shareholder would pay on Fund dividends, capital gain distributions, if any, or any realized gains on the sale of Fund shares.

Net asset value or “NAV” is the value of one share of a fund as calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market return (Market Price) is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of a fund are listed for trading, as of the time that such fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary trading (4/28/17), the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested at Market Price and NAV.

Your dividend income will vary depending on dividends or interest paid by securities in the Fund’s portfolio, adjusted for operating expenses. Capital gain distributions are net profits realized from the sale of portfolio securities.

Total Annual Operating Expenses⁷

All investments involve risks, including possible loss of principal. Stock prices fluctuate, sometimes rapidly and dramatically, due to factors affecting individual companies, particular industries or sectors, or general market conditions. Smaller, mid-sized and relatively new or unseasoned companies can be particularly sensitive to changing economic conditions, and their prospects for growth are less certain than those of larger, more established companies. Historically, these securities have experienced more price volatility than larger company stocks, especially over the short term. Smaller companies may be more susceptible to particular events or economic conditions, less certain growth prospects, lack of depth of management and funds for growth and development and limited or less developed product lines and markets. There can be no assurance that the Fund’s multi-factor stock selection process will enhance performance. Exposure to such investment factors may detract from performance in some market environments, perhaps for extended periods. Performance of the Fund may vary significantly from the performance of an index, as a result of transactions costs, expenses and other factors. Events such as the spread of deadly diseases, disasters, and financial, political or social disruptions, may heighten risks and adversely affect performance. The Fund’s prospectus also includes a description of the main investment risks.

Russia’s military invasion of Ukraine in February 2022, the resulting responses by the United States and other countries, and the potential for wider conflict could increase volatility and uncertainty in the financial markets and adversely affect regional and global economies. The United States and other countries have imposed broad-ranging economic sanctions on Russia and certain Russian individuals, banking entities and corporations as a response to its invasion of Ukraine. The United States and other countries have also imposed economic sanctions on Belarus and may impose sanctions on other countries that support Russia’s military invasion. These sanctions, as well as any other economic consequences related to the invasion, such as additional sanctions, boycotts or changes in consumer or purchaser preferences or cyberattacks on governments, companies or individuals, may further decrease the value and liquidity of certain Russian securities and securities of issuers in other countries that are subject to economic sanctions related to the invasion.

ETFs trade like stocks, fluctuate in market value and may trade at prices above or below their net asset value. Brokerage commissions and ETF expenses will reduce returns.

1. Effective December 1, 2017, the Fund adopted a unified fee structure whereby Management has agreed to reimburse the Fund’s acquired fund fees and expenses (if any) and pay all of the ordinary operating expenses of the Fund, including custody, transfer agency, and Trustee fees and expenses, among others, but excluding: (i) payments under the Fund’s Rule 12b-1 plan (if any); (ii) brokerage expenses (including any costs incidental to transactions in portfolio securities or instruments); (iii) taxes; (iv) interest (including borrowing costs and dividend expenses on securities sold short and overdraft charges); (v) litigation expenses (including litigation to which the Trust or a Fund may be a party and indemnification of the Trustees and officers with respect thereto); and (vi) other non-routine or extraordinary expenses.

Your Fund’s Expenses

As a Fund shareholder, you can incur two types of costs: (1) transaction costs, including brokerage commissions on purchases and sales of Fund shares; and (2) ongoing Fund costs, including management fees and other Fund expenses. All funds have ongoing costs, sometimes referred to as operating expenses. The table below shows ongoing costs of investing in the Fund and can help you understand these costs and compare them with those of other funds. The table assumes a $1,000 investment held for the six months indicated.

Actual Fund Expenses

The table below provides information about actual account values and actual expenses in the columns under the heading “Actual.” In these columns the Fund’s actual return, which includes the effect of Fund expenses, is used to calculate the “Ending Account Value.” You can estimate the expenses you paid during the period by following these steps (of course, your account value and expenses will differ from those in this illustration): Divide your account value by $1,000 (if your account had an $8,600 value, then $8,600 ÷ $1,000 = 8.6). Then multiply the result by the number in the row under the headings “Actual” and “Expenses Paid During Period” (if Actual Expenses Paid During Period were $7.50, then 8.6 x $7.50 = $64.50). In this illustration, the actual expenses paid this period are $64.50.

Hypothetical Example for Comparison with Other Funds

Under the heading “Hypothetical” in the table, information is provided about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. This information may not be used to estimate the actual ending account balance or expenses you paid for the period, but it can help you compare ongoing costs of investing in the Fund with those of other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds.

Please note that expenses shown in the table are meant to highlight ongoing costs and do not reflect any transactional costs. Therefore, information under the heading “Hypothetical” is useful in comparing ongoing costs only, and will not help you compare total costs of owning different funds. In addition, if transactional costs were included, your total costs would have been higher.

1. Expenses are equal to the annualized expense ratio for the six-month period as indicated above—in the far right column—multiplied by the simple average account value over the period indicated, and then multiplied by 182/365 to reflect the one-half year period.

2. Reflects expenses after fee waivers and expense reimbursements.
