     II    Western Asset Short Duration Income ETF

Fund overview

Q. What is the Fund’s investment strategy?

A.Western Asset Short Duration Income ETF (the “Fund”) seeks current income. Under normal market conditions, the Fund invests at least 80% of its net assets, plus borrowings for investment purposes, in “investment grade” fixed income securities. Corporate debt securities, including notes, bonds, debentures and commercial paper, are fixed income securities usually issued by businesses to finance their operations. These securities may be secured or unsecured, may be issued by U.S. or foreign entities and may carry variable or floating rates of interest. The Fund may invest in Rule 144A securities. The Fund may also invest in other short-duration fixed-income securities, such as floating rate loans and structured debt and in cash or cash equivalents such as money market securities. Securities in which the Fund will invest will be U.S. dollar-denominated although they may be issued by a foreign corporation or a U.S. affiliate of a foreign corporation, or a foreign government or its agencies and instrumentalities.

Although the Fund may invest in securities of any maturity, the Fund will normally maintain an effective durationⁱ, of three years or less. Investment grade securities are those rated by a rating agency at the time of purchase in one of the top four ratings categories (e.g.,BBB- or higher by S&P Global Ratings (“S&P”) or Baa3 or higher by Moody’s Investors Service, Inc. (“Moody’s”)) or, if unrated, that we judge to be of comparable credit quality. The Fund may also invest up to 15% of its assets in fixed income securities that are below investment grade (e.g., BB+ or lower by S&P or Ba1 or lower by Moody’s). Below investment grade securities are commonly known as “junk bonds” or “high yield securities.”

The Fund may also invest up to 15% of its assets in mortgage-backed securities (“MBS”) and asset-backed securities (“ABS”), including collateralized debt obligations (“CDOs”). The Fund may use derivatives, from time to time, in order to change the investment characteristics of its portfolio (such as shortening or lengthening duration) and/or for other purposes.

Information showing the number of days the market price of the Fund’s shares was greater than the Fund’s net asset value (“NAV”) and the number of days it was less than the Fund’s NAV (i.e., premium or discount) for various time periods is available by visiting the Fund’s website at www.leggmason.com/etf.

Looking for additional information?

The Fund’s daily NAV is availableon-line at www.leggmason.com/etf. The Fund is traded under the symbol “WINC” and its closing market price is available on most financial websites. In a continuing effort to provide information concerning the Fund, shareholders may call1-877-721-1926 (toll free), Monday through Friday from 8:00 a.m. to 5:30 p.m. Eastern time, for the Fund’s current NAV, market price and other information.

RISKS: The Fund is newly organized, with a limited history of operations. All investments are subject to risk including the possible loss of principal. Fixed-income securities involve interest rate, credit, inflation and reinvestment risks; and possible loss of principal. As interest rates rise, the value of fixed-income securities falls. High-yield securities include greater price volatility, illiquidity and possibility of default. International investments are subject to special risks, including currency fluctuations, social, economic and political uncertainties, which could increase volatility. These risks are magnified in emerging markets. Derivatives, such as options and futures, can be illiquid, may disproportionately increase losses, and have a potentially large impact on fund performance. The use of leverage may increase volatility and possibility of loss. Asset-backed, mortgage-backed or mortgage related securities are subject to prepayment and extension risks. Active management and diversification do not ensure gains or protect against market declines. Please see the Fund’s prospectus for a more complete discussion of these and other risks and the Fund’s investment strategies.

ⁱ  Effective duration is a duration calculation for bonds with embedded options. Effective duration takes into account that expected cash flows will fluctuate as interest rates change. Please note, duration measures the sensitivity of price (the value of principal) of a fixed-income investment to a change in interest rates.

Fund expenses(unaudited)

Example

As a shareholder of the Fund, you may incur two types of costs: (1) transaction costs, such as brokerage commissions paid on purchases and sales of Fund shares; and (2) ongoing costs, management fees; and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other funds.

This example is based on an investment of $1,000 invested on February 1, 2019 and held for the six months ended July 31, 2019, unless otherwise noted.

Actual expenses

The table below titled “Based on Actual Total Return” provides information about actual account values and actual expenses. You may use the information provided in this table, together with the amount you invested, to estimate the expenses that you paid over the period. To estimate the expenses you paid on your account, divide your ending account value by $1,000 (for example, an $8,600 ending account value divided by $1,000 = 8.6), then multiply the result by the number under the heading entitled “Expenses Paid During the Period”.

Hypothetical example for comparison purposes

The table below titled “Based on Hypothetical Total Return” provides information about hypothetical account values and hypothetical expenses based on the actual expense ratio and an assumed rate of return of 5.00% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use the information provided in this table to compare the ongoing costs of investing in the Fund and other funds. To do so, compare the 5.00% hypothetical example relating to the Fund with the 5.00% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table below are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as brokerage commissions paid on purchases and sales of Fund shares. Therefore, the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher.

¹   For the period February 7, 2019 (inception date) to July 31, 2019.

²  Assumes the reinvestment of all distributions, including returns of capital, if any, at net asset value. Total return is not annualized, as it may not be representative of the total fund return for the year. Performance figures may reflect fee waivers and/or expense reimbursements. In the absence of fee waivers and/or expense reimbursements, the total return would have been lower. Past performance is no guarantee of future results.

³  Expenses (net of fee waivers and/or expense reimbursements) are equal to the Fund’s annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent fiscal period (174), then divided by 365.

⁴  For the six months ended July 31, 2019.

⁵  Expenses (net of fee waivers and/or expense reimbursements) are equal to the Fund’s annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent fiscal half-year (181), then divided by 365.

Spread duration(unaudited)

Economic exposure — July 31, 2019

Spread duration measures the sensitivity to changes in spreads. The spread over Treasuries is the annual risk-premium demanded by investors to holdnon-Treasury securities. Spread duration is quantified as the % change in price resulting from a 100 basis points change in spreads. For a security with positive spread duration, an increase in spreads would result in a price decline and a decline in spreads would result in a price increase. This chart highlights the market sector exposure of the Fund’s sectors relative to the selected benchmark sectors as of the end of the reporting period.

Notes to financial statements

1. Organization and significant accounting policies

Western Asset Short Duration Income ETF (the “Fund”) is a separate diversified investment series of Legg Mason ETF Investment Trust (the “Trust”). The Trust, a Maryland statutory trust, is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as anopen-end management investment company.

The Fund is an actively managed exchange-traded fund (“ETF”). ETFs are funds that trade like other publicly-traded securities. Unlike shares of a mutual fund, which can be bought from and redeemed by the issuing fund by all shareholders at a price based on net asset value (“NAV”), shares of the Fund may be directly purchased from and redeemed by the Fund at NAV solely by certain large institutional investors who have entered into agreements with the Fund’s distributor (“Authorized Participants”). Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

Shares of the Fund are listed and traded at market prices on NASDAQ. The market price for the Fund’s shares may be different from the Fund’s NAV. The Fund issues and redeems shares at NAV only in blocks of a specified number of shares or multiples thereof (“Creation Units”). Only Authorized Participants may purchase or redeem Creation Units directly with the Fund at NAV. Creation Units generally are issued and redeemed in cash. However, Creation Units may also be issued and redeemed partiallyin-kind for a basket of securities and partially in cash. Except when aggregated in Creation Units, shares of the Fund are not redeemable securities. Shareholders who are not Authorized Participants may not redeem shares directly from the Fund at NAV.

The following are significant accounting policies consistently followed by the Fund and are in conformity with U.S. generally accepted accounting principles (“GAAP”). Estimates and assumptions are required to be made regarding assets, liabilities and changes in net assets resulting from operations when financial statements are prepared. Changes in the economic environment, financial markets and any other parameters used in determining these estimates could cause actual results to differ. Subsequent events have been evaluated through the date the financial statements were issued.

(a) Investment valuation.The valuations for fixed income securities (which may include, but are not limited to, corporate, government, municipal, mortgage-backed, collateralized mortgage obligations and asset-backed securities) and certain derivative instruments are typically the prices supplied by independent third party pricing services, which may use market prices or broker/dealer quotations or a variety of valuation techniques and methodologies. The independent third party pricing services use inputs that are observable such as issuer details, interest rates, yield curves, prepayment speeds, credit risks/spreads, default rates and quoted prices for similar securities. Investments inopen-end funds are valued at the closing net asset value per share of each fund on the day of valuation. Futures contracts are valued daily at the settlement price established by the board of trade or exchange on

     20    Western Asset Short Duration Income ETF 2019 Annual Report

which they are traded. Equity securities for which market quotations are available are valued at the last reported sales price or official closing price on the primary market or exchange on which they trade. When the Fund holds securities or other assets that are denominated in a foreign currency, the Fund will use the currency exchange rates, generally determined as of 4:00 p.m. (London Time). If independent third party pricing services are unable to supply prices for a portfolio investment, or if the prices supplied are deemed by the manager to be unreliable, the market price may be determined by the manager using quotations from one or more broker/dealers or at the transaction price if the security has recently been purchased and no value has yet been obtained from a pricing service or pricing broker. When reliable prices are not readily available, such as when the value of a security has been significantly affected by events after the close of the exchange or market on which the security is principally traded, but before the Fund calculates its net asset value, the Fund values these securities as determined in accordance with procedures approved by the Fund’s Board of Trustees.

The Board of Trustees is responsible for the valuation process and has delegated the supervision of the daily valuation process to the Legg Mason North Atlantic Fund Valuation Committee (the “Valuation Committee”). The Valuation Committee, pursuant to the policies adopted by the Board of Trustees, is responsible for making fair value determinations, evaluating the effectiveness of the Fund’s pricing policies, and reporting to the Board of Trustees. When determining the reliability of third party pricing information for investments owned by the Fund, the Valuation Committee, among other things, conducts due diligence reviews of pricing vendors, monitors the daily change in prices and reviews transactions among market participants.

The Valuation Committee will consider pricing methodologies it deems relevant and appropriate when making fair value determinations. Examples of possible methodologies include, but are not limited to, multiple of earnings; discount from market of a similar freely traded security; discounted cash-flow analysis; book value or a multiple thereof; risk premium/yield analysis; yield to maturity; and/or fundamental investment analysis. The Valuation Committee will also consider factors it deems relevant and appropriate in light of the facts and circumstances. Examples of possible factors include, but are not limited to, the type of security; the issuer’s financial statements; the purchase price of the security; the discount from market value of unrestricted securities of the same class at the time of purchase; analysts’ research and observations from financial institutions; information regarding any transactions or offers with respect to the security; the existence of merger proposals or tender offers affecting the security; the price and extent of public trading in similar securities of the issuer or comparable companies; and the existence of a shelf registration for restricted securities.

Western Asset Short Duration Income ETF 2019 Annual Report      21   

Notes to financial statements (cont’d)

For each portfolio security that has been fair valued pursuant to the policies adopted by the Board of Trustees, the fair value price is compared against the last available and next available market quotations. The Valuation Committee reviews the results of such back testing monthly and fair valuation occurrences are reported to the Board of Trustees quarterly.

The Fund uses valuation techniques to measure fair value that are consistent with the market approach and/or income approach, depending on the type of security and the particular circumstance. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable securities. The income approach uses valuation techniques to discount estimated future cash flows to present value.

GAAP establishes a disclosure hierarchy that categorizes the inputs to valuation techniques used to value assets and liabilities at measurement date. These inputs are summarized in the three broad levels listed below:

• Level 1 — quoted prices in active markets for identical investments

• Level 2 — other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.)

• Level 3 — significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments)

The inputs or methodologies used to value securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used in valuing the Fund’s assets and liabilities carried at fair value:

† See Schedule of Investments for additional detailed categorizations.

(b) Futures contracts.The Fund uses futures contracts generally to gain exposure to, or hedge against, changes in interest rates or gain exposure to, or hedge against, changes in certain asset classes. A futures contract represents a commitment for the future purchase or sale of an asset at a specified price on a specified date.

Upon entering into a futures contract, the Fund is required to deposit cash or securities with a broker in an amount equal to a certain percentage of the contract amount. This is known as the ‘‘initial margin’’ and subsequent payments (‘‘variation margin’’) are made or received by the Fund each day, depending on the daily fluctuation in the value of the contract. For certain futures, including foreign denominated futures, variation margin is not settled daily, but is recorded as a net variation margin payable or receivable. The daily changes in contract value are recorded as unrealized gains or losses in the Statement of Operations and the Fund recognizes a realized gain or loss when the contract is closed.

Futures contracts involve, to varying degrees, risk of loss in excess of the amounts reflected in the financial statements. In addition, there is the risk that the Fund may not be able to enter into a closing transaction because of an illiquid secondary market.

(c) Loan participations.The Fund may invest in loans arranged through private negotiation between one or more financial institutions. The Fund’s investment in any such loan may be in the form of a participation in or an assignment of the loan. In connection with purchasing participations, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement related to the loan, or any rights ofoff-set against the borrower and the Fund may not benefit directly from any collateral supporting the loan in which it has purchased the participation.

The Fund assumes the credit risk of the borrower, the lender that is selling the participation and any other persons interpositioned between the Fund and the borrower. In the event of the insolvency of the lender selling the participation, the Fund may be treated as a general creditor of the lender and may not benefit from anyoff-set between the lender and the borrower.

(d) Securities traded on a when-issued and delayed delivery basis.The Fund may trade securities on a when-issued or delayed delivery basis. In when-issued and delayed delivery transactions, the securities are purchased or sold by the Fund with payment and

Western Asset Short Duration Income ETF 2019 Annual Report      23   

Notes to financial statements (cont’d)

delivery taking place in the future in order to secure what is considered to be an advantageous price and yield to the Fund at the time of entering into the transaction.

Purchasing such securities involves risk of loss if the value of the securities declines prior to settlement. These securities are subject to market fluctuations and their current value is determined in the same manner as for other securities.

(e) Credit and market risk.The Fund invests in high-yield and emerging market instruments that are subject to certain credit and market risks. The yields of high-yield and emerging market debt obligations reflect, among other things, perceived credit and market risks. The Fund’s investments in securities rated below investment grade typically involve risks not associated with higher rated securities including, among others, greater risk related to timely and ultimate payment of interest and principal, greater market price volatility and less liquid secondary market trading. The consequences of political, social, economic or diplomatic changes may have disruptive effects on the market prices of investments held by the Fund. The Fund’s investments innon-U.S. dollar denominated securities may also result in foreign currency losses caused by devaluations and exchange rate fluctuations.

Investments in securities that are collateralized by real estate mortgages are subject to certain credit and liquidity risks. When market conditions result in an increase in default rates of the underlying mortgages and the foreclosure values of underlying real estate properties are materially below the outstanding amount of these underlying mortgages, collection of the full amount of accrued interest and principal on these investments may be doubtful. Such market conditions may significantly impair the value and liquidity of these investments and may result in a lack of correlation between their credit ratings and values.

(f) Foreign investment risks.The Fund’s investments in foreign securities may involve risks not present in domestic investments. Since securities may be denominated in foreign currencies, may require settlement in foreign currencies or pay interest or dividends in foreign currencies, changes in the relationship of these foreign currencies to the U.S. dollar can significantly affect the value of the investments and earnings of the Fund. Foreign investments may also subject the Fund to foreign government exchange restrictions, expropriation, taxation or other political, social or economic developments, all of which affect the market and/or credit risk of the investments.

(g) Counterparty risk and credit-risk-related contingent features of derivative instruments.The Fund may invest in certain securities or engage in other transactions, where the Fund is exposed to counterparty credit risk in addition to broader market risks. The Fund may invest in securities of issuers, which may also be considered counterparties as trading partners in other transactions. This may increase the risk of loss in the event of default or bankruptcy by the counterparty or if the counterparty otherwise fails to meet its contractual obligations. The Fund’s subadviser attempts to mitigate counterparty risk by (i) periodically assessing the creditworthiness of its trading partners, (ii) monitoring and/or

     24    Western Asset Short Duration Income ETF 2019 Annual Report

limiting the amount of its net exposure to each individual counterparty based on its assessment and (iii) requiring collateral from the counterparty for certain transactions. Market events and changes in overall economic conditions may impact the assessment of such counterparty risk by the subadviser. In addition, declines in the values of underlying collateral received may expose the Fund to increased risk of loss.

With exchange traded and centrally cleared derivatives, there is less counterparty risk to the Fund since the exchange or clearinghouse, as counterparty to such instruments, guarantees against a possible default. The clearinghouse stands between the buyer and the seller of the contract; therefore, the credit risk is limited to failure of the clearinghouse. While offset rights may exist under applicable law, the Fund does not have a contractual right of offset against a clearing broker or clearinghouse in the event of a default of the clearing broker or clearinghouse.

The Fund has entered into master agreements, such as an International Swaps and Derivatives Association, Inc. Master Agreement (“ISDA Master Agreement”) or similar agreement, with certain of its derivative counterparties that governover-the-counter derivatives and provide for general obligations, representations, agreements, collateral posting terms, netting provisions in the event of default or termination and credit related contingent features. The credit related contingent features include, but are not limited to, a percentage decrease in the Fund’s net assets or NAV over a specified period of time. If these credit related contingent features were triggered, the derivatives counterparty could terminate the positions and demand payment or require additional collateral.

Under an ISDA Master Agreement, the Fund may, under certain circumstances, offset with the counterparty certain derivative financial instruments’ payables and/or receivables with collateral held and/or posted and create one single net payment. However, absent an event of default by the counterparty or a termination of the agreement, the terms of the ISDA Master Agreements do not result in an offset of reported amounts of financial assets and financial liabilities in the Statement of Assets and Liabilities across transactions between the Fund and the applicable counterparty. The enforceability of the right to offset may vary by jurisdiction.

Collateral requirements differ by type of derivative. Collateral or margin requirements are set by the broker or exchange clearinghouse for exchange traded derivatives while collateral terms are contract specific forover-the-counter traded derivatives. Cash collateral that has been pledged to cover obligations of the Fund under derivative contracts, if any, will be reported separately in the Statement of Assets and Liabilities. Securities pledged as collateral, if any, for the same purpose are noted in the Schedule of Investments.

As of July 31, 2019, the Fund did not have any open OTC derivative transactions with credit related contingent features in a net liability position.

(h) Security transactions and investment income.Security transactions are accounted for on a trade date basis. Interest income (including interest income frompayment-in-kind

Western Asset Short Duration Income ETF 2019 Annual Report      25   

Notes to financial statements (cont’d)

securities), adjusted for amortization of premium and accretion of discount, is recorded on the accrual basis. Paydown gains and losses on mortgage- and asset-backed securities are recorded as adjustments to interest income. Dividend income is recorded on theex-dividend date for dividends received in cash and/or securities. The cost of investments sold is determined by use of the specific identification method. To the extent any issuer defaults or a credit event occurs that impacts the issuer, the Fund may halt any additional interest income accruals and consider the realizability of interest accrued up to the date of default or credit event.

(i) Distributions to shareholders.Distributions from net investment income are declared and paid monthly. Distributions of net realized gains, if any, are declared at least annually. Distributions to shareholders of the Fund are recorded on theex-dividend date and are determined in accordance with income tax regulations, which may differ from GAAP.

(j) Federal and other taxes.It is the Fund’s policy to comply with the federal income and excise tax requirements of the Internal Revenue Code of 1986 (the “Code”), as amended, applicable to regulated investment companies. Accordingly, the Fund intends to distribute its taxable income and net realized gains, if any, to shareholders in accordance with timing requirements imposed by the Code. Therefore, no federal or state income tax provision is required in the Fund’s financial statements.

Management has analyzed the Fund’s tax positions taken on income tax returns for all open tax years and has concluded that as of July 31, 2019, no provision for income tax is required in the Fund’s financial statements. The Fund’s federal and state income and federal excise tax returns for tax years for which the applicable statutes of limitations have not expired are subject to examination by the Internal Revenue Service and state departments of revenue.

(k) Reclassification.GAAP requires that certain components of net assets be reclassified to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or net asset value per share. During the current period, the Fund had no reclassifications.

2. Investment management agreement and other transactions with affiliates

for paying interest expenses, taxes, brokerage expenses, future12b-1 fees (if any), acquired fund fees and expenses, extraordinary expenses and the management fee payable to LMPFA under the investment management agreement.

Under the investment management agreement and subject to the general supervision of the Fund’s Board of Trustees, LMPFA provides or causes to be furnished all investment management, supervisory, administrative and other services reasonably necessary for the operation of the Fund, including certain distribution services (provided pursuant to a separate distribution agreement) and investment advisory services (provided pursuant to separate subadvisory agreements) under a unitary fee structure. The Fund pays an investment management fee, calculated daily and paid monthly, at an annual rate of 0.29% of the Fund’s average daily net assets.

As compensation for its subadvisory services, LMPFA pays Western Asset monthly 70% of the management fee paid by the Fund to LMPFA, net of (i) all fees and expenses incurred by LMPFA under the investment management agreement (including without limitation any subadvisory fee paid to another subadviser to the Fund) and (ii) expense waivers, if any, and reimbursements. Western Asset pays Western Asset Singapore, Western Asset Japan and Western Asset London a monthly subadvisory fee in an amount equal to 100% of the management fee paid to Western Asset on the assets that Western Asset allocates to each suchnon-U.S. subadviser to manage.

Legg Mason Investor Services, LLC, a wholly-owned broker-dealer subsidiary of Legg Mason, serves as the distributor of Creation Units for the Fund on an agency basis.

The Fund’s Board of Trustees has adopted a Rule12b-1 shareholder services and distribution plan and under that plan, the Fund is authorized to pay service and/or distribution fees calculated at an annual rate of up to 0.25% of its average daily net assets. No service and/or distribution fees are currently paid by the Fund, and there are no current plans to impose these fees.

All officers and one Trustee of the Trust are employees of Legg Mason or its affiliates and do not receive compensation from the Trust.

Western Asset Short Duration Income ETF 2019 Annual Report      29   

Notes to financial statements (cont’d)

eliminates and modifies certain existing fair value disclosure requirements. ASU2018-13 would be effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years; however, management has elected to early adopt ASU2018-13. The impact of the Fund’s adoption was limited to changes in the Fund’s financial statement disclosures regarding fair value, primarily those disclosures related to transfers between levels of the fair value hierarchy.

In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of July 31, 2019, and the results of its operations, changes in its net assets, and the financial highlights for the period February 7, 2019 (commencement of operations) through July 31, 2019 in conformity with accounting principles generally accepted in the United States of America.

Board approval of management and subadvisory agreements(unaudited)

At a meeting of the Trust’s Board of Trustees, the Board considered the initial approval for atwo-year period of the management agreement pursuant to which Legg Mason Partners Fund Advisor, LLC (the “Manager”) provides the Fund with investment advisory and administrative services, thesub-advisory agreement pursuant to which Western Asset Management Company, LLC (“Western Asset”) providesday-to-day management of the Fund’s portfolio, and thesub-sub-advisory agreements pursuant to which Western Asset Management Company Limited in London (“Western Asset London”), Western Asset Management Company Ltd in Japan (“Western Asset Japan”) and Western Asset Management Company Pte. Ltd. In Singapore (“Western Asset Singapore” and collectively with Western Asset, Western Asset London and Western Asset Japan, the“Sub-Advisers”) provide certainsub-sub-advisory services relating to currency transactions and investments innon-U.S. dollar-denominated securities and related foreign currency instruments. (The management agreement,sub-advisory agreement andsub-sub-advisory agreements are collectively referred to as the “Agreements.”) The Manager and theSub-Advisers are wholly-owned subsidiaries of Legg Mason, Inc. The Trustees who are not “interested persons” (as defined in the Investment Company Act of 1940, as amended (the “Independent Trustees”)) of the Fund were assisted in their review by Fund counsel and independent legal counsel and met with independent legal counsel in executive sessions separate from representatives of the Manager and theSub-Advisers. The Independent Trustees requested and received information from the Manager and theSub-Advisers they deemed reasonably necessary for their review of the Agreements and the services to be provided by the Manager and theSub-Advisers. Included was information about the Manager, theSub-Advisers and the Fund’s distributor, as well as the management,sub-advisory and distribution arrangements for the Fund.

In voting to approve the Agreements, the Independent Trustees considered whether the approval of the Agreements would be in the best interests of the Fund and its prospective shareholders, an evaluation based on several factors including those discussed below.

Nature, extent and quality of the services to be provided to the fund under the management agreement,sub-advisory agreement andsub-sub-advisory agreements

The Board received and considered information regarding the nature, extent and quality of services to be provided to the Fund by the Manager and theSub-Advisers under the respective Agreements. The Trustees also considered the Manager’s supervisory activities over theSub-Advisers. In addition, the Independent Trustees received and considered other information regarding the administrative and other services to be rendered to the Fund by the Manager, including services specific to the Fund’s operation as an exchange-traded fund. The Board noted information received at regular meetings throughout the year related to the services rendered by the Manager in its management of other funds in the Legg Mason fund complex, and the Manager’s role in coordinating the activities of theSub-Advisers and the Fund’s other service providers. The Board’s evaluation of the services to be provided by

     32    Western Asset Short Duration Income ETF

the Manager and theSub-Advisers took into account the Board’s knowledge and familiarity gained as Trustees of funds in the Legg Mason fund complex, including the scope and quality of the investment management and other capabilities of the Manager and theSub-Advisers and the quality of the Manager’s administrative and other services. The Board observed that the scope of services provided by the Manager had expanded over time as a result of regulatory and other developments, including maintaining and monitoring its own expanded compliance programs and the compliance program to be implemented for the Fund specific to the Fund’s operation as an exchange-traded fund. The Board reviewed information received from the Manager and the Fund’s Chief Compliance Officer regarding the Fund’s compliance policies and procedures established pursuant to Rule38a-1 under the Investment Company Act of 1940, as amended.

The Board reviewed the qualifications, backgrounds and responsibilities of the Fund’s senior personnel and the portfolio management team that would be primarily responsible for theday-to-day portfolio management of the Fund. The Trustees then discussed with representatives of management the portfolio management strategy of the Fund’s portfolio managers. The Trustees noted that the Manager and theSub-Advisers were committed to providing the resources necessary to assist the Fund’s portfolio managers in managing the Fund. The Board also considered, based on its knowledge of the Manager and the Manager’s affiliates, the financial resources available to the Manager’s parent organization, Legg Mason, Inc.

The Board considered the division of responsibilities among the Manager and theSub-Advisers and the oversight provided by the Manager. The Board also considered the arrangements for communication and processing of orders for creations and redemptions of Fund shares. In addition, management also reported to the Board on, among other things, its business plans regarding exchange-traded funds, recent organizational changes, portfolio manager compensation plan and policy regarding portfolio managers’ ownership of fund shares.

The Board concluded that, overall, it was satisfied with the nature, extent and quality of services expected to be provided under the respective Agreement by the Manager and theSub-Advisers.

Fund performance

Because the Fund had not commenced operations and the Manager and theSub-Advisers were newly-appointed, the Trustees could not consider their investment performance in managing the Fund’s portfolio as a factor in evaluating the Agreements during the meeting. The Trustees discussed with representatives of the Manager the investment strategy and process to be employed by the Manager and theSub-Advisers in the management of the Fund’s assets. The Trustees noted the reputation and experience of the Manager and the

Western Asset Short Duration Income ETF      33   

Board approval of management and subadvisory agreements(unaudited) (cont’d)

Sub-Advisers, as well as the respective portfolio managers’ experience. The Board determined that these factors also supported a decision to approve the Agreements.

Management fees and expense ratios

The Board reviewed and considered the contractual management fee rate (the “Contractual Management Fee”) payable by the Fund to the Manager in light of the nature, extent and quality of the management andsub-advisory services expected to be provided by the Manager and theSub-Advisers, respectively. The Board noted that the Manager, and not the Fund, pays thesub-advisory fees to theSub-Advisers and, accordingly, that the retention of theSub-Advisers would not increase the fees and expenses to be incurred by the Fund. The Board also noted that the Manager will pay all fund expenses, other than the Contractual Management Fee and certain other expenses, and will provide the Fund with regulatory compliance and administrative services, office facilities and Fund officers (including the Fund’s chief financial, chief legal and chief compliance officers), and that the Manager will coordinate and oversee the provision of services to the Fund by other fund service providers, including theSub-Advisers. Because of the Fund’s “unitary fee” structure, the Board recognized that the Fund’s fees and expenses will vary within a much smaller range and the Manager will bear the risk that Fund expenses may increase over time. On the other hand, the Board noted that it is possible that the Manager could earn a profit on the fees charged under the management agreement and would benefit from any price decreases in third-party services covered by the management agreement.

Management also discussed with the Board the Fund’s proposed distribution arrangements, including how the Fund’s distributor would market the Fund. The Board received and considered information regarding the maximum charges associated with creations and redemptions for cash and estimated standard transaction fees to be imposed by the Fund in connection with effecting purchases or redemptions of Creation Units. Additionally, the Board received and considered information about the Fund’s fees and expenses, along with information about management fees and operating expenses of other funds, including exchange-traded funds that do not have a unitary fee structure such as that proposed for the Fund, which showed that the Fund’s Contractual Management Fee was competitive with the management fees paid by such other funds.

Manager profitability

Because the Fund had not commenced operations and the Manager and theSub-Advisers were newly-appointed, the Trustees could not consider the profitability of the Manager and theSub-Advisers and their affiliates in providing services to the Fund as a factor in evaluating the Agreements during the meeting.

     34    Western Asset Short Duration Income ETF

Economies of scale

The Board discussed any economies of scale or other efficiencies that may result from increases in the Fund’s assets. The Board noted that the Fund’s management agreement did not provide for any breakpoints in the Fund’s Contractual Management Fee to the extent the assets of the Fund increase. The Board noted that should material economies of scale exist in the future, a breakpoint structure for the Fund may be appropriate, and that it would continue to monitor the sharing of economies of scale to determine the appropriateness of adding breakpoints in the future. The Board also noted that there are various ways to share potential economies of scale with Fund shareholders and that it appeared that the benefits of any economies of scale would be appropriately shared with shareholders through increased investment in fund management and administration resources.

Taking all of the above into consideration, the Board determined that the management fee was reasonable in light of the comparative expense information and the nature, extent and quality of the services expected to be provided to the Fund under the Agreements.

Other benefits to the manager

The Board considered other benefits expected to be received by the Manager and its affiliates, including theSub-Advisers, as a result of the Manager’s relationship with the Fund, including the opportunity to offer additional products and services to Fund shareholders. In light of the expected costs of providing investment management and other services to the Fund and the Manager’s commitment to the Fund, the other ancillary benefits that the Manager and its affiliates expect to receive were considered reasonable.

Based on their discussions and considerations, including those described above, the Trustees approved the Agreements.

No single factor reviewed by the Board was identified by the Board as the principal factor in determining whether to approve the Agreements.
