First Trust International Equity Opportunities ETF

<p>Summary Information</p>

<p>Investment Objective</p>

The First Trust International Equity Opportunities ETF (the "Fund"), formerly First Trust International IPO ETF, seeks investment results that correspond generally to the price and yield (before the Fund's fees and expenses) of an index called the IPOX International Index (the "Index").

<p>Fees and Expenses of the Fund</p>

The following table describes the fees and expenses you may pay if you buy and hold shares of the Fund. Investors purchasing and selling shares may be subject to costs (including customary brokerage commissions) charged by their broker, which are not reflected in the table below.

<p> <b>Shareholder Fees</b> <br />(fees paid directly from your investment)</p>

Shareholder Fees	First Trust International Equity Opportunities ETF First Trust International Equity Opportunities ETF
Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)	none

<p></p><p> <b>Annual Fund Operating Expenses</b> <br />(expenses that you pay each year as a percentage of the value of your investment)</p>

Annual Fund Operating Expenses	First Trust International Equity Opportunities ETF First Trust International Equity Opportunities ETF
Management Fees	0.70%
Distribution and Service (12b-1) Fees	none	[1]
Other Expenses	none	[2]
Total Annual Fund Operating Expenses	0.70%

<p>Example</p>

The example below is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. This example does not take into account customary brokerage commissions that you pay when purchasing or selling shares of the Fund in the secondary market.

The example assumes that you invest $10,000 in the Fund for the time periods indicated. The example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain at current levels until January 31, 2019, and thereafter at 0.95% to represent the imposition of the 12b-1 fee of 0.25% per annum of the Fund's average daily net assets. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example, No Redemption	1 Year	3 Years	5 Years	10 Years
First Trust International Equity Opportunities ETF | First Trust International Equity Opportunities ETF | USD ($)	72	278	501	1,144

<p>Portfolio Turnover</p>

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 58% of the average value of its portfolio.

<p>Principal Investment Strategies</p>

The Fund will normally invest at least 90% of its net assets (including investment borrowings) in common stocks and/or depositary receipts that comprise the Index. The Fund, using an indexing investment approach, attempts to replicate, before fees and expenses, the performance of the Index. The Fund's investment advisor seeks a correlation of 0.95 or better (before fees and expenses) between the Fund's performance and the performance of the Index; a figure of 1.00 would represent perfect correlation.

The Index is owned and is developed, maintained and sponsored by IPOX^® Schuster LLC (the "Index Provider"). The Index is a market-cap weighted portfolio measuring the performance of the top 50 non-U.S. companies, including companies domiciled in emerging markets, ranked quarterly by market capitalization in the IPOX^® Global Composite Index (the "Base Index"). The Index includes the 50 largest and typically most liquid initial public offerings ("IPOs") and spin-offs of companies legally domiciled outside the United States that trade on an accessible global stock exchange. An IPO is a public offering in which the shares of stock in a company are sold to the general public for the first time on an exchange. On a quarterly basis, each stock in the Fund's portfolio is capped at 10% of the Fund's net assets. Additionally, at each quarterly rebalance, stocks whose weights exceed 5% of the Fund's net assets will not, in the aggregate, comprise more than 50% of the Fund's net assets. The Index Provider periodically calculates a constituent equity turnover to determine each constituent's eligibility for the Index based on its liquidity.

The Index methodology starts with the Base Index, a rules-based index that measures the global performance of IPOs and spin-offs. The applicable stocks in the Base Index are ranked by total market capitalization, which is the total number of shares outstanding times closing price. Generally, the Index is comprised of mid-, large- and mega-capitalization companies. Although market capitalization ranges are constantly fluctuating, the Index Provider generally considers mid- to large/mega-capitalization to be approximately $2 billion to $80 billion. The inception date of the Index was July 25, 2014. In general, eligible constituents are added to the Base Index on the sixth day of trading and remain eligible to be included in the Base Index for approximately four years. Because a component is generally eligible for the Index after six days of public trading, the Fund may not have access to the gains derived from the initial run-up in the IPO's price. The Fund may invest in the components of the Index through depository receipts, such as American Depository Receipts ("ADRs") or Global Depository Receipts ("GDRs"). The Fund will be concentrated in a sector or industry to the extent that the Index is so concentrated. As of September 30, 2017, the Fund had significant investments in financial companies.

<p>Principal Risks</p>

You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. There can be no assurance that the Fund's investment objective will be achieved.

AUTHORIZED PARTICIPANT CONCENTRATION RISK. Only an authorized participant (as defined in the "Frequent Purchases and Redemptions" Section) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that act as authorized participants. To the extent that these institutions exit the business or are unable to proceed with creation and/or redemption orders with respect to the Fund and no other authorized participant is able to step forward to create or redeem, in either of these cases, Fund shares may trade at a discount to the Fund's net asset value and possibly face delisting.

CHINA AND HONG KONG RISK. The Fund may invest in H shares, depositary receipts and U.S.-listed common stock of companies that are domiciled in China, including Hong Kong. Some Chinese companies are listed on both the Hong Kong Stock Exchange with H shares and the Shanghai Stock Exchange with A shares. Price differentials between H shares and A shares of the same company may be significant. Also, price fluctuations of A shares are limited to either 5% or 10% per trading day, while no such limitations exist for H shares. Investing in securities of companies in China involves additional risks, including, but not limited to: the economy of China differs, often unfavorably, from the U.S. economy in such respects as structure, general development, government involvement, wealth distribution, rate of inflation, growth rate, allocation of resources and capital reinvestment; the central government has historically exercised substantial control over virtually every sector of the Chinese economy through administrative regulation and/or state ownership; and actions of the Chinese central and local government authorities continue to have a substantial effect on economic conditions in China. Furthermore, China's economy is dependent on the economies of other Asian countries and can be significantly affected by currency fluctuations and increasing competition from Asia's other emerging economies.

The Fund is also subject to certain risks associated specifically with Hong Kong, including Hong Kong's political and economic environment and the volatility of and the concentration of real estate companies listed on the Hong Kong Stock Exchange. Because of Hong Kong's reversion to China, any increase in uncertainty as to the economic and political status of Hong Kong, or a deterioration of the relationship between China and the United States, could have negative implications on stocks listed on the Hong Kong Stock Exchange. Securities prices on the Hong Kong Stock Exchange can be highly volatile and are sensitive to developments in Hong Kong and China, as well as other world markets.

CURRENCY RISK. The Fund may hold investments that are denominated in non-U.S. currencies, or in securities that provide exposure to such currencies, currency exchange rates or interest rates denominated in such currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund's investments and the value of Fund shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.

CYBER SECURITY RISK. As the use of Internet technology has become more prevalent in the course of business, the Fund has become more 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 the Fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause the Fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. Cyber security breaches may involve unauthorized access to the Fund's digital information systems through "hacking" or malicious software coding, but may also result from outside attacks such as denial-of-service attacks through efforts to make network services unavailable to intended users. In addition, cyber security breaches of the 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 the Fund to many of the same risks associated with direct cyber security breaches. The Fund has established risk management systems designed to reduce the risks associated with cyber security. However, there is no guarantee that such efforts will succeed, especially because the Fund does not directly control the cyber security systems of issuers or third party service providers.

DEPOSITARY RECEIPTS RISK. Depositary receipts may be less liquid than the underlying shares in their primary trading market. Any distributions paid to the holders of depositary receipts are usually subject to a fee charged by the depositary. Holders of depositary receipts may have limited voting rights, and investment restrictions in certain countries may adversely impact the value of depositary receipts because such restrictions may limit the ability to convert the equity shares into depositary receipts and vice versa. Such restrictions may cause the equity shares of the underlying issuer to trade at a discount or premium to the market price of the depositary receipts.

EQUITY SECURITIES RISK. Because the Fund invests in equity securities, the value of the Fund's shares will fluctuate with changes in the value of these 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.

EUROPE RISK. Investments in a single region, even though representing a number of different countries within the region, may be affected by common economic forces and other factors. The Fund is subject to greater risks of adverse events which occur in the European region and may experience greater volatility than a fund that is more broadly diversified geographically. Political or economic disruptions in European countries, even in countries in which the Fund is not invested, may adversely affect security values and thus the Fund's holdings. A significant number of countries in Europe are member states in the European Union (the "EU"), and the member states no longer control their own monetary policies by directing independent interest rates for their currencies. In these member states, the authority to direct monetary policies, including money supply and official interest rates for the Euro, is exercised by the European Central Bank.

FINANCIAL COMPANIES RISK. Financial companies are especially subject to the adverse effects of economic recession, currency exchange rates, government regulation, decreases in the availability of capital, volatile interest rates, portfolio concentrations in geographic markets and in commercial and residential real estate loans, and competition from new entrants in their fields of business.

FLUCTUATION OF NET ASSET VALUE RISK. The net asset value of shares of the Fund will generally fluctuate with changes in the market value of the Fund's holdings. The market prices of shares will generally fluctuate in accordance with changes in net asset value as well as the relative supply of and demand for shares on the Exchange. The Fund's investment advisor cannot predict whether shares will trade below, at or above their net asset value because the shares trade on the Exchange at market prices and not at net asset value. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for shares will be closely related to, but not identical to, the same forces influencing the prices of the holdings of the Fund trading individually or in the aggregate at any point in time. However, given that shares can only be purchased and redeemed either in-kind or for cash in Creation Units, and only to and from broker-dealers and large institutional investors that have entered into participation agreements (unlike shares of closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset value), the Fund's investment advisor believes that large discounts or premiums to the net asset value of shares should not be sustained.

INDEX CONSTITUENT RISK. The Fund may be a constituent of one or more indices. As a result, the 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 the 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, the Fund's net asset value could be negatively impacted and the Fund's market price may be significantly below the Fund's net asset value during certain periods. In addition, index rebalances may potentially result in increased trading activity. To the extent buying or selling activity increases, the Fund can be exposed to increased brokerage costs and adverse tax consequences and the market price of the Fund can be negatively affected.

IPO RISK. The Fund invests in companies that have recently conducted an initial public offering. The stocks of such companies are often subject to extreme price volatility and speculative trading. These stocks may have exhibited above- average price appreciation in connection with the initial public offering prior to inclusion in the Index. The price of stocks included in the Index may not continue to appreciate and the performance of these stocks may not replicate the performance exhibited in the past.

MARKET RISK. Market risk is the risk that a particular security owned by the Fund or shares of the Fund in general may fall in value. Securities are subject to market fluctuations caused by such factors as economic, political, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Shares of the Fund could decline in value or underperform other investments.

MARKET MAKER RISK. If the Fund has lower average daily trading volumes, it may rely on a small number of third-party market makers to provide a market for the purchase and sale of shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund's net asset value and the price at which the Fund's shares are trading on the Exchange which could result in a decrease in value of the Fund's shares. In addition, decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund's portfolio securities and the Fund's market price. This reduced effectiveness could result in Fund shares trading at a discount to net asset value and also in greater than normal intraday bid-ask spreads for Fund shares.

NON-CORRELATION RISK. The Fund's return may not match the return of the Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Index, and may incur costs in buying and selling securities, especially when rebalancing the Fund's portfolio holdings to reflect changes in the composition of the Index. In addition, the Fund's portfolio holdings may not exactly replicate the securities included in the Index or the ratios between the securities included in the Index.

NON-DIVERSIFICATION RISK. The Fund is classified as "non-diversified" under the Investment Company Act of 1940, as amended (the "1940 Act"). As a result, the Fund is only limited as to the percentage of its assets which may be invested in the securities of any one issuer by the diversification requirements imposed by the Internal Revenue Code of 1986, as amended. The Fund may invest a relatively high percentage of its assets in a limited number of issuers. As a result, the Fund may be more susceptible to a single adverse economic or regulatory occurrence affecting one or more of these issuers, experience increased volatility and be highly invested in certain issuers.

NON-U.S. SECURITIES AND EMERGING MARKETS RISK. 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; 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. These risks may be heightened for securities of companies located in, or with significant operations in, emerging market countries.

REPLICATION MANAGEMENT RISK. The Fund is exposed to additional market risk due to its policy of investing principally in the securities included in the Index. As a result of this policy, securities held by the Fund will generally not be bought or sold in response to market fluctuations.

SMALL FUND RISK. The Fund currently has fewer assets than larger funds, and like other smaller funds, large inflows and outflows may impact the Fund's market exposure for limited periods of time. This impact may be positive or negative, depending on the direction of market movement during the period affected.

SMALLER COMPANIES RISK. Small and/or mid capitalization companies may be more vulnerable to adverse general market or economic developments, and their securities may be less liquid and may experience greater price volatility than larger, more established companies as a result of several factors, including limited trading volumes, products or financial resources, management inexperience and less publicly available information. Accordingly, such companies are generally subject to greater market risk than larger, more established companies.

TRADING ISSUES RISK. Although the shares of the Fund are listed for trading on the Exchange, there can be no assurance that an active trading market for such shares will develop or be maintained. Trading in shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in shares inadvisable. In addition, trading in shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange's "circuit breaker" rules. Market makers are under no obligation to make a market in the Fund's shares, and authorized participants are not obligated to submit purchase or redemption orders for Creation Units. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. The Fund may have difficulty maintaining its listing on the Exchange in the event the Fund's assets are small or the Fund does not have enough shareholders.

<p>Annual Total Return</p>

The bar chart and table below illustrate the annual calendar year returns of the Fund based on net asset value as well as the average annual Fund and Index returns. The bar chart and table provide an indication of the risks of investing in the Fund by showing changes in the Fund's performance from year-to-year and by showing how the Fund's average annual total returns based on net asset value compared to those of the Index and a broad-based market index. See "Total Return Information" for additional performance information regarding the Fund. The Fund's performance information is accessible on the Fund's website at www.ftportfolios.com.

Returns before taxes do not reflect the effects of any income or capital gains taxes. All after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of any state or local tax. Returns after taxes on distributions reflect the taxed return on the payment of dividends and capital gains. Returns after taxes on distributions and sale of shares assume you sold your shares at period end, and, therefore, are also adjusted for any capital gains or losses incurred. Returns for the market indices do not include expenses, which are deducted from Fund returns, or taxes.

Your own actual after-tax returns will depend on your specific tax situation and may differ from what is shown here. After-tax returns are not relevant to investors who hold Fund shares in tax-deferred accounts such as individual retirement accounts (IRAs) or employee-sponsored retirement plans.
