First Trust Exchange-Traded Fund III

January 31, 2020 (Unaudited)

1. Organization

First Trust Exchange-Traded Fund III (the “Trust”) is an open-end management investment company organized as a Massachusetts business trust on January 9, 2008, and is registered with the Securities and Exchange Commission (“SEC”) under the Investment Company Act of 1940, as amended (the “1940 Act”).

The Trust currently consists of fifteen funds that are offering shares. This report covers the following funds, each a non-diversified series of the Trust:

First Trust Horizon Managed Volatility Domestic ETF – (NYSE Arca, Inc. (“NYSE Arca”) ticker “HUSV”)

First Trust Horizon Managed Volatility Developed International ETF – (NYSE Arca ticker “HDMV”)

Each fund represents a separate series of shares of beneficial interest in the Trust (each a “Fund” and collectively, the “Funds”). Unlike conventional mutual funds, each Fund issues and redeems shares on a continuous basis, at net asset value (“NAV”), only in large specified blocks consisting of 50,000 shares called a “Creation Unit.” Creation Units are issued and redeemed in-kind for securities in which a Fund invests and, in certain circumstances, for cash. Except when aggregated in Creation Units, the shares are not redeemable securities of a Fund.

Each Fund is an actively managed exchange-traded fund. The investment objective of each Fund is to provide capital appreciation.

Under normal market conditions, HUSV seeks to achieve its investment objective by investing at least 80% of its net assets (including investment borrowings) in common stocks of domestic companies listed and traded on U.S. national securities exchanges that Horizon Investments, LLC (“Horizon” or the “Sub-Advisor”) believes exhibit low future expected volatility.

Under normal market conditions, HDMV seeks to achieve its investment objective by investing at least 80% of its net assets (including investment borrowings) in common stocks and depositary receipts of developed market companies listed and traded on non-U.S. exchanges that Horizon believes exhibit low future expected volatility.

There can be no assurance that a Fund will achieve its investment objective. The Funds may not be appropriate for all investors.

2. Significant Accounting Policies

The Funds are each considered an investment company and follow accounting and reporting guidance under Financial Accounting Standards Board Accounting Standards Codification Topic 946, “Financial Services-Investment Companies.” The following is a summary of significant accounting policies consistently followed by the Funds in the preparation of the financial statements. The preparation of the financial statements in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates.

A. Portfolio Valuation

Each Fund’s NAV is determined daily as of the close of regular trading on the New York Stock Exchange (“NYSE”), normally 4:00 p.m. Eastern time, on each day the NYSE is open for trading. If the NYSE closes early on a valuation day, the NAV is determined as of that time. Foreign securities are priced using data reflecting the earlier closing of the principal markets for those securities. Each Fund’s NAV is calculated by dividing the value of all assets of each Fund (including accrued interest and dividends), less all liabilities (including accrued expenses and dividends declared but unpaid), by the total number of shares outstanding.

Each Fund’s investments are valued daily at market value or, in the absence of market value with respect to any portfolio securities, at fair value. Market value prices represent last sale or official closing prices from a national or foreign exchange (i.e., a regulated market) and are primarily obtained from third-party pricing services. Fair value prices represent any prices not considered market value prices and are either obtained from a third-party pricing service or are determined by the Pricing Committee of the Funds’ investment advisor, First Trust Advisors L.P. (“First Trust” or the “Advisor”), in accordance with valuation procedures adopted by the Trust’s Board of Trustees, and in accordance with provisions of the 1940 Act. Investments valued by the Advisor’s Pricing Committee, if any, are footnoted as such in the footnotes to the Portfolio of Investments. Each Fund’s investments are valued as follows:

Common stocks, real estate investment trusts (“REITs”) and other equity securities listed on any national or foreign exchange (excluding The Nasdaq Stock Market LLC (“Nasdaq”) and the London Stock Exchange Alternative Investment Market (“AIM”)) are valued at the last sale price on the exchange on which they are principally traded or, for Nasdaq and AIM securities, the official closing price. Securities traded on more than one securities exchange are valued at the last sale price or official closing price, as applicable, at the close of the securities exchange representing the principal market for such securities.

Securities traded in an over-the-counter market are fair valued at the mean of their most recent bid and asked price, if available, and otherwise at their closing bid price.

Certain securities may not be able to be priced by pre-established pricing methods. Such securities may be valued by the Trust’s Board of Trustees or its delegate, the Advisor’s Pricing Committee, at fair value. These securities generally include, but are not limited to, restricted securities (securities which may not be publicly sold without registration under the Securities Act of 1933, as amended) for which a third-party pricing service is unable to provide a market price; securities whose trading has been formally suspended; a security whose market or fair value price is not available from a pre-established pricing source; a security with respect to which an event has occurred that is likely to materially affect the value of the security after the market has closed but before the calculation of a Fund’s NAV or make it difficult or impossible to obtain a reliable market quotation; and a security whose price, as provided by the third-party pricing service, does not reflect the security’s fair value. As a general principle, the current fair value of a security would appear to be the amount which the owner might reasonably expect to receive for the security upon its current sale. When fair value prices are used, generally they will differ from market quotations or official closing prices on the applicable exchanges. A variety of factors may be considered in determining the fair value of such securities, including, but not limited to, the following:

1)	the type of security;
2)	the size of the holding;
3)	the initial cost of the security;
4)	transactions in comparable securities;
5)	price quotes from dealers and/or third-party pricing services;
6)	relationships among various securities;
7)	information obtained by contacting the issuer, analysts, or the appropriate stock exchange;
8)	an analysis of the issuer’s financial statements; and
9)	the existence of merger proposals or tender offers that might affect the value of the security.

If the securities in question are foreign securities, the following additional information may be considered:

1)	the value of similar foreign securities traded on other foreign markets;
2)	ADR trading of similar securities;
3)	closed-end fund or exchange-traded fund trading of similar securities;
4)	foreign currency exchange activity;
5)	the trading prices of financial products that are tied to baskets of foreign securities;
6)	factors relating to the event that precipitated the pricing problem;
7)	whether the event is likely to recur; and
8)	whether the effects of the event are isolated or whether they affect entire markets, countries or regions.

Because foreign markets may be open on different days than the days during which investors may transact in the shares of a Fund, the value of the Fund’s securities may change on the days when investors are not able to transact in the shares of the Fund. The value of securities denominated in foreign currencies is converted into U.S. dollars using exchange rates determined daily as of the close of regular trading on the NYSE.

The Funds are subject to fair value accounting standards that define fair value, establish the framework for measuring fair value and provide a three-level hierarchy for fair valuation based upon the inputs to the valuation as of the measurement date. The three levels of the fair value hierarchy are as follows:

•	Level 1 – Level 1 inputs are quoted prices in active markets for identical investments. An active market is a market in which transactions for the investment occur with sufficient frequency and volume to provide pricing information on an ongoing basis.
•	Level 2 – Level 2 inputs are observable inputs, either directly or indirectly, and include the following:

o	Quoted prices for similar investments in active markets.
o	Quoted prices for identical or similar investments in markets that are non-active. A non-active market is a market where there are few transactions for the investment, the prices are not current, or price quotations vary substantially either over time or among market makers, or in which little information is released publicly.
o	Inputs other than quoted prices that are observable for the investment (for example, interest rates and yield curves observable at commonly quoted intervals, volatilities, prepayment speeds, loss severities, credit risks, and default rates).
o	Inputs that are derived principally from or corroborated by observable market data by correlation or other means.

•	Level 3 – Level 3 inputs are unobservable inputs. Unobservable inputs may reflect the reporting entity’s own assumptions about the assumptions that market participants would use in pricing the investment.

The inputs or methodologies used for valuing investments are not necessarily an indication of the risk associated with investing in those investments. A summary of the inputs used to value each Fund’s investments as of January 31, 2020, is included with each Fund’s Portfolio of Investments.

B. Securities Transactions and Investment Income

Securities transactions are recorded as of the trade date. Realized gains and losses from securities transactions are recorded on the identified cost basis. Dividend income is recorded on the ex-dividend date. Interest income is recorded daily on the accrual basis.

Withholding taxes and tax reclaims on foreign dividends have been provided for in accordance with each Fund’s understanding of the applicable country’s tax rules and rates.

Distributions received from a Fund’s investments in REITs may be comprised of return of capital, capital gains, and income. The actual character of the amounts received during the year are not known until after the REITs’ fiscal year end. A Fund records the character of distributions received from the REITs during the year based on estimates available. The characterization of distributions received by a Fund may be subsequently revised based on information received from the REITs after their tax reporting periods conclude.

C. Foreign Currency

The books and records of the Funds are maintained in U.S. dollars. Foreign currencies, investments and other assets and liabilities are translated into U.S. dollars at the exchange rates prevailing at the end of the period. Purchases and sales of investments and items of income and expense are translated on the respective dates of such transactions. Unrealized gains and losses on assets and liabilities, other than investments in securities, which result from changes in foreign currency exchange rates have been included in “Net change in unrealized appreciation (depreciation) on foreign currency translation” on the Statements of Operations. Unrealized gains and losses on investments in securities which result from changes in foreign exchange rates are included with fluctuations arising from changes in market price and are included in “Net change in unrealized appreciation (depreciation) on investments” on the Statements of Operations. Net realized foreign currency gains and losses include the effect of changes in exchange rates between trade date and settlement date on investment security transactions, foreign currency transactions and interest and dividends received and are included in “Net realized gain (loss) on foreign currency transactions” on the Statements of Operations. The portion of foreign currency gains and losses related to fluctuations in exchange rates between the initial purchase settlement date and subsequent sale trade date is included in “Net realized gain (loss) on investments” on the Statements of Operations.

D. Dividends and Distributions to Shareholders

Dividends from net investment income, if any, are declared and paid quarterly by each Fund, or as the Board of Trustees may determine from time to time. Distributions of net realized capital gains earned by each Fund, if any, are distributed at least annually.

Distributions from income and capital gains are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP. Certain capital accounts in the financial statements are periodically adjusted for permanent differences in order to reflect their tax character. These permanent differences are primarily due to the varying treatment of income and gain/loss on portfolio securities held by the Funds and have no impact on net assets or NAV per share. Temporary differences, which arise from recognizing certain items of income, expense and gain/loss in different periods for financial statement and tax purposes, will reverse at some time in the future.

The tax character of distributions paid by each Fund during the fiscal year ended July 31, 2019, was as follows:

January 31, 2020 (Unaudited)

The Trust has multiple service agreements with Brown Brothers Harriman & Co. (“BBH”). Under the service agreements, BBH performs custodial, fund accounting, certain administrative services, and transfer agency services for the Funds. As custodian, BBH is responsible for custody of each Fund’s assets. As fund accountant and administrator, BBH is responsible for maintaining the books and records of each Fund’s securities and cash. As transfer agent, BBH is responsible for maintaining shareholder records for each Fund.

Each Trustee who is not an officer or employee of First Trust, any sub-advisor or any of their affiliates (“Independent Trustees”) is paid a fixed annual retainer that is allocated equally among each fund in the First Trust Fund Complex. Each Independent Trustee is also paid an annual per fund fee that varies based on whether the fund is a closed-end or other actively managed fund, a defined-outcome fund or an index fund.

Additionally, the Lead Independent Trustee and the Chairmen of the Audit Committee, Nominating and Governance Committee and Valuation Committee are paid annual fees to serve in such capacities, with such compensation allocated pro rata among each fund in the First Trust Fund Complex based on net assets. Independent Trustees are reimbursed for travel and out-of-pocket expenses in connection with all meetings. The Lead Independent Trustee and Committee Chairmen rotate every three years. The officers and “Interested” Trustee receive no compensation from the Trust for acting in such capacities.

4. Purchases and Sales of Securities

For the six months ended January 31, 2020, the cost of purchases and proceeds from sales of investment securities for each Fund, excluding short-term investments and in-kind transactions, were as follows:

For the six months ended January 31, 2020, the cost of in-kind purchases and proceeds from in-kind sales for each Fund were as follows:

	Purchases		Sales
First Trust Horizon Managed Volatility Domestic ETF	$ 154,877,762		$ 112,960,840
First Trust Horizon Managed Volatility Developed International ETF	46,949,898		25,584,059

5. Creations, Redemptions and Transaction Fees

Shares are created and redeemed by each Fund only in Creation Unit size aggregations of 50,000 shares in transactions with broker-dealers or large institutional investors that have entered into a participation agreement (an “Authorized Participant”). In order to purchase Creation Units of a Fund, an Authorized Participant must deposit (i) a designated portfolio of equity securities determined by First Trust (the “Deposit Securities”) and generally make or receive a cash payment referred to as the “Cash Component,” which is an amount equal to the difference between the NAV of the Fund shares (per Creation Unit Aggregations) and the market value of the Deposit Securities, and/or (ii) cash in lieu of all or a portion of the Deposit Securities. If the Cash Component is a positive number (i.e., the NAV per Creation Unit Aggregation exceeds the Deposit Amount), the Authorized Participant will deliver the Cash Component. If the Cash Component is a negative number (i.e., the NAV per Creation Unit Aggregation is less than the Deposit Amount), the Authorized Participant will receive the Cash Component. Authorized Participants purchasing Creation Units must pay to BBH, as transfer agent, a creation transaction fee (the “Creation Transaction Fee”) regardless of the number of Creation Units purchased in the transaction. The Creation Transaction Fee may vary and is based on the composition of the securities included in the respective Fund’s portfolio and the countries in which the transactions are settled. The Creation Transaction Fee may increase or decrease with changes in each Fund’s portfolio.The price for each Creation Unit will equal the daily NAV per share times the number of shares in a Creation Unit plus the fees described above and, if applicable, any operational processing and brokerage costs, transfer fees or stamp taxes. When a Fund permits an Authorized Participant to substitute cash or a different security in lieu of depositing one or more of the requisite Deposit Securities, the Authorized Participant may also be assessed an amount to cover the cost of purchasing the Deposit Securities and/or disposing of the substituted securities, including operational processing and brokerage costs, transfer fees, stamp taxes, and part or all of the spread between the expected bid and offer side of the market related to such Deposit Securities and/or substitute securities.

Authorized Participants redeeming Creation Units must pay to BBH, as transfer agent, a redemption transaction fee (the “Redemption Transaction Fee”), regardless of the number of Creation Units redeemed in the transaction. The Redemption Transaction Fee may vary and is based on the composition of the securities included in the respective Fund’s portfolio and the countries in which the transactions are settled. The Redemption Transaction Fee may increase or decrease with changes in each Fund’s portfolio. Each Fund reserves the right to effect redemptions in cash. An Authorized Participant may request cash redemption in lieu of securities; however, a Fund may, in its discretion, reject any such request.

6. Distribution Plan

The Board of Trustees adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the 1940 Act. In accordance with the Rule 12b-1 plan, each Fund is authorized to pay an amount up to 0.25% of its average daily net assets each year to reimburse First Trust Portfolios L.P. (“FTP”), the distributor of the Funds, for amounts expended to finance activities primarily intended to result in the sale of Creation Units or to provide investor services. FTP may also use this amount to compensate securities dealers or other persons that are Authorized Participants for providing distribution assistance, including broker-dealer and shareholder support and educational and promotional services.

No 12b-1 fees are currently paid by the Funds, and pursuant to a contractual arrangement, no 12b-1 fees will be paid any time before November 30, 2020.

7. Indemnification

The Trust, on behalf of the Funds, has a variety of indemnification obligations under contracts with its service providers. The Trust’s maximum exposure under these arrangements is unknown. However, the Trust has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote.

8. Subsequent Events

Management has evaluated the impact of all subsequent events to the Funds through the date the financial statements were issued, and has determined that there were no subsequent events requiring recognition or disclosure in the financial statements that have not already been disclosed.

Proxy Voting Policies and Procedures

A description of the policies and procedures that the Trust uses to determine how to vote proxies and information on how each Fund voted proxies relating to portfolio securities during the most recent 12-month period ended June 30 is available (1) without charge, upon request, by calling (800) 988-5891; (2) on each Fund’s website at www.ftportfolios.com; and (3) on the Securities and Exchange Commission’s (“SEC”) website at www.sec.gov.

Portfolio Holdings

Each Fund files portfolio holdings information for each month in a fiscal quarter within 60 days after the end of the relevant fiscal quarter on Form N-PORT. Portfolio holdings information for the third month of each fiscal quarter will be publicly available on the SEC’s website at www.sec.gov. Each Fund’s complete schedule of portfolio holdings for the second and fourth quarters of each fiscal year is included in the semi-annual and annual reports to shareholders, respectively, and is filed with the SEC on Form N-CSR. The semi-annual and annual report for each Fund is available to investors within 60 days after the period to which it relates. Each Fund’s Forms N-PORT and Forms N-CSR are available on the SEC’s website listed above.

Risk Considerations

Risks are inherent in all investing. Certain general risks that may be applicable to a Fund are identified below, but not all of the material risks relevant to each Fund are included in this report and not all of the risks below apply to each Fund. The material risks of investing in each Fund are spelled out in its prospectus, statement of additional information and other regulatory filings. Before investing, you should consider each Fund’s investment objective, risks, charges and expenses, and read each Fund’s prospectus and statement of additional information carefully. You can download each Fund’s prospectus at www.ftportfolios.com or contact First Trust Portfolios L.P. at (800) 621-1675 to request a prospectus, which contains this and other information about each Fund.

Concentration Risk. To the extent that a fund is able to invest a large percentage of its assets in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development may affect the value of the fund’s investments more than if the fund were more broadly diversified. A fund that tracks an index will be concentrated to the extent the fund’s corresponding index is concentrated. A concentration makes a fund more susceptible to any single occurrence and may subject the fund to greater market risk than a fund that is not concentrated.

Credit Risk. Credit risk is the risk that an issuer of a security will be unable or unwilling to make dividend, interest and/or principal payments when due and the related risk that the value of a security may decline because of concerns about the issuer’s ability to make such payments.

Cyber Security Risk. The funds are susceptible to potential operational risks through breaches in cyber security. A breach in cyber security refers to both intentional and unintentional events that may cause a fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause a fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. In addition, cyber security breaches of a fund’s third-party service providers, such as its administrator, transfer agent, custodian, or sub-advisor, as applicable, or issuers in which the fund invests, can also subject a fund to many of the same risks associated with direct cyber security breaches.

Derivatives Risk. To the extent a fund uses derivative instruments such as futures contracts, options contracts and swaps, the fund may experience losses because of adverse movements in the price or value of the underlying asset, index or rate, which may be magnified by certain features of the derivative. These risks are heightened when a fund’s portfolio managers use derivatives to enhance the fund’s return or as a substitute for a position or security, rather than solely to hedge (or offset) the risk of a position or security held by the fund.

Equity Securities Risk. To the extent a fund invests in equity securities, the value of the fund’s shares will fluctuate with changes in the value of the equity securities. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant stock market, such as market volatility, or when political or economic events affecting the issuers occur. In addition, common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur in the equity market as a whole, or they may occur in only a particular country, company, industry or sector of the market.

ETF Risk. The shares of an ETF trade like common stock and represent an interest in a portfolio of securities. The risks of owning an ETF generally reflect the risks of owning the underlying securities, although lack of liquidity in an ETF could result in it being more volatile and ETFs have management fees that increase their costs. Shares of an ETF trade on an exchange at market prices rather than

Page 27

First Trust Exchange-Traded Fund III

January 31, 2020 (Unaudited)

net asset value, which may cause the shares to trade at a price greater than net asset value (premium) or less than net asset value (discount). In times of market stress, decisions by market makers to reduce or step away from their role of providing a market for an ETF’s shares, or decisions by an ETF’s authorized participants that they are unable or unwilling to proceed with creation and/or redemption orders of an ETF’s shares, could result in shares of the ETF trading at a discount to net asset value and in greater than normal intraday bid-ask spreads.

Fixed Income Securities Risk. To the extent a fund invests in fixed income securities, the fund will be subject to credit risk, income risk, interest rate risk, liquidity risk and prepayment risk. Income risk is the risk that income from a fund’s fixed income investments could decline during periods of falling interest rates. Interest rate risk is the risk that the value of a fund’s fixed income securities will decline because of rising interest rates. Liquidity risk is the risk that a security cannot be purchased or sold at the time desired, or cannot be purchased or sold without adversely affecting the price. Prepayment risk is the risk that the securities will be redeemed or prepaid by the issuer, resulting in lower interest payments received by the fund. In addition to these risks, high yield securities, or “junk” bonds, are subject to greater market fluctuations and risk of loss than securities with higher ratings, and the market for high yield securities is generally smaller and less liquid than that for investment grade securities.

Index Constituent Risk. Certain funds may be a constituent of one or more indices. As a result, such a fund may be included in one or more index-tracking exchange-traded funds or mutual funds. Being a component security of such a vehicle could greatly affect the trading activity involving a fund, the size of the fund and the market volatility of the fund. Inclusion in an index could significantly increase demand for the fund and removal from an index could result in outsized selling activity in a relatively short period of time. As a result, a fund’s net asset value could be negatively impacted and the fund’s market price may be significantly below its net asset value during certain periods.

Index Provider Risk. To the extent a fund seeks to track an index, it is subject to Index Provider Risk. There is no assurance that the Index Provider will compile the Index accurately, or that the Index will be determined, maintained, constructed, reconstituted, rebalanced, composed, calculated or disseminated accurately. To correct any such error, the Index Provider may carry out an unscheduled rebalance or other modification of the Index constituents or weightings, which may increase the fund’s costs. The Index Provider does not provide any representation or warranty in relation to the quality, accuracy or completeness of data in the Index, and it does not guarantee that the Index will be calculated in accordance with its stated methodology. Losses or costs associated with any Index Provider errors generally will be borne by the fund and its shareholders.

Investment Companies Risk. To the extent a fund invests in the securities of other investment vehicles, the fund will incur additional fees and expenses that would not be present in a direct investment in those investment vehicles. Furthermore, the fund’s investment performance and risks are directly related to the investment performance and risks of the investment vehicles in which the fund invests.

LIBOR Risk. To the extent a fund invests in floating or variable rate obligations that use the London Interbank Offered Rate (“LIBOR”) as a reference interest rate, it is subject to LIBOR Risk. In 2017, the United Kingdom’s Financial Conduct Authority announced that LIBOR will cease to be available for use after 2021. The unavailability or replacement of LIBOR may affect the value, liquidity or return on certain fund investments and may result in costs incurred in connection with closing out positions and entering into new trades. Any potential effects of the transition away from LIBOR on the fund or on certain instruments in which the fund invests can be difficult to ascertain, and they may vary depending on a variety of factors. Any such effects of the transition away from LIBOR, as well as other unforeseen effects, could result in losses to the fund.

Management Risk. To the extent that a fund is actively managed, it is subject to management risk. In managing an actively-managed fund’s investment portfolio, the fund’s portfolio managers will apply investment techniques and risk analyses that may not have the desired result. There can be no guarantee that a fund will meet its investment objective.

Market Risk. Securities held by a fund, as well as shares of a fund itself, are subject to market fluctuations caused by factors such as general economic conditions, political events, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Shares of a fund could decline in value or underperform other investments as a result of the risk of loss associated with these market fluctuations. In addition, local, regional or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on a fund and its investments. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. The outbreak of the respiratory disease designated as COVID-19 in December 2019 has caused significant volatility and declines in global financial markets, which have caused losses for investors. The impact of this COVID-19 pandemic may be short term or may last for an extended period of time, and in either case could result in a substantial economic downturn or recession.

Non-U.S. Securities Risk. To the extent a fund invests in non-U.S. securities, it is subject to additional risks not associated with securities of domestic issuers. Non-U.S. securities are subject to higher volatility than securities of domestic issuers due to: possible adverse political, social or economic developments; restrictions on foreign investment or exchange of securities; lack of liquidity;

Page 28

First Trust Exchange-Traded Fund III

January 31, 2020 (Unaudited)

currency exchange rates; excessive taxation; government seizure of assets; different legal or accounting standards; and less government supervision and regulation of exchanges in foreign countries. Investments in non-U.S. securities may involve higher costs than investments in U.S. securities, including higher transaction and custody costs, as well as additional taxes imposed by non-U.S. governments. These risks may be heightened for securities of companies located, or with significant operations, in emerging market countries.

Passive Investment Risk. To the extent a fund seeks to track an index, the fund will invest in the securities included in, or representative of, the index regardless of their investment merit. A fund generally will not attempt to take defensive positions in declining markets.
