Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)

None

    

Annual Fund Operating Expenses
(expenses that you pay each year as a percentage of the value of your investment)

Management Fees	0.83%
Distribution and Service (12b-1) Fees	0.00%
Other Expenses	0.00%
Total Annual Fund Operating Expenses	0.83%

Example

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. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 Year	3 Years	5 Years	10 Years
$85	$265	$460	$1,025

Portfolio Turnover

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 87% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund will seek to achieve its investment objective by investing at least 80% of its net assets (including investment borrowings) in a portfolio of equity securities of developed market companies, including through investments in common stock, depositary receipts and common and preferred shares of real estate investment trusts (“REITs”), and forward foreign currency exchange contracts and currency spot transactions used to hedge the Fund’s exposure to the currencies in which the equity securities of such developed market companies are denominated (each, a “Developed Market currency” and, collectively, the “Developed Market currencies”). Developed market companies are those companies (i) whose securities are traded principally on a stock exchange in a developed market country, (ii) that have a primary business office in a developed market country, or (iii) that have at least 50% of their assets in, or derive at least 50% of their revenues or profits from, a developed market country. Developed market countries currently include the countries comprising the Morgan Stanley Capital International World Index or countries considered to be developed by the World Bank, the International Finance Corporation or the United Nations. Under normal market conditions, the Fund will invest in at least three countries and at least 40% of its net assets in countries other than the United States. The securities in which the Fund may invest must be listed on a U.S. or non-U.S. securities exchange. The Fund may invest in small, mid and large capitalization companies.

The Fund utilizes a dynamic currency hedging strategy through the use of forward foreign currency exchange contracts and currency spot transactions to hedge up to 100% of the Fund’s currency exposure. As a result of this hedging strategy, the portion of the Fund’s portfolio securities which are subject to currency hedging transactions may vary widely, from 0% to 100% of the portfolio securities. A forward contract on foreign currency is an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days agreed upon by the parties from the date of the contract, at a price set on the date of the contract. A forward foreign currency exchange contract may reduce the Fund’s exposure to changes in the value of the currency it will deliver and increase its

exposure to changes in the value of the currency it will receive for the duration of the contract. The effect on the value of the Fund is similar to selling securities denominated in one currency and purchasing securities denominated in another currency. The Fund also may enter into currency spot transactions as part of its dynamic currency hedging strategy. A currency spot transaction is an agreement between two parties to buy or sell a specific currency for delivery on a date that is typically two business days from the date of the agreement, as opposed to a date set in the future. The underlying currencies of the forward foreign currency exchange contracts and currency spot transactions included in the Fund’s policy relating to the investment of at least 80% of its net assets (including investment borrowings) will be limited to Developed Market currencies.

The Fund also may invest up to 20% of its net assets in companies of emerging market countries and forward foreign currency exchange contracts and currency spot transactions used to hedge the Fund’s exposure to non-Developed Market currencies as well as any proxy currency hedging transactions involving non-Developed Market currencies determined to be representative of, and serve as a proxy for, Developed Market currencies. Such emerging market companies are companies (i) whose securities are traded principally on a stock exchange in a country that is not a developed market country, (ii) that have a primary business office in a country that is not a developed market country, or (iii) that have at least 50% of their assets in, or derive at least 50% of their revenues or profits from, a country that is not a developed market country. The equity securities of emerging market companies in which the Fund may invest include investments in common stock, depositary receipts and common and preferred shares of REITs.

In selecting the portfolio securities of the Fund, RiverFront Investment Group, LLC, the Fund’s sub-adviser (“RIG” or the “Sub-Advisor”), assembles a portfolio of eligible countries and/or securities based on several core attributes, including, but not limited to, value, quality and momentum. The Sub-Advisor considers multiple factors within each core attribute, such as the price-to-book value of a security when determining value and a company’s cash as a percentage of the company’s market capitalization when determining quality. The Sub-Advisor then assigns each qualifying security a score based on its core attributes and selects the individual securities with the highest scores for investment. In doing so, the Sub-Advisor utilizes its proprietary optimization process to maximize the percentage of high-scoring securities included in the portfolio in accordance with country, sector and risk factor (e.g., beta, quality, volatility) limitations. The Sub-Advisor also considers the market capitalization of the companies in which the Fund may invest, and the trading volume of a company’s shares in the secondary market. As of January 31, 2020, the Fund had significant investments in Japanese issuers, Asian issuers and European issuers, although this may change from time to time. To the extent the Fund invests a significant portion of its assets in a given jurisdiction or investment sector, the Fund may be exposed to the risks associated with that jurisdiction or investment sector.

In managing the Fund’s currency exposure, the Sub-Advisor deploys a dynamic currency hedging strategy based on a proprietary hedging methodology that considers a combination of quantitative measures, such as interest rate differentials, central bank balance sheet expansion/contraction and price momentum, and qualitative measures, such as formal and informal guidance from central bankers.

To the extent permitted under applicable law, percentage limitations described in this prospectus are generally as of the time of investment by the Fund and may be exceeded on a going-forward basis as a result of market fluctuations affecting the Fund’s portfolio securities.

Principal Risks

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. The order of the below risk factors does not indicate the significance of any particular risk factor.

ASIA RISK. The Fund is subject to certain risks specifically associated with investments in the securities of Asian issuers. Many Asian economies have experienced rapid growth and industrialization, and there is no assurance that this growth rate will be maintained. Some Asian economies are highly dependent on trade, and economic conditions in other countries within and outside Asia can impact these economies. Certain of these economies may be adversely affected by trade or policy disputes with its major trade partners. There is also a high concentration of market capitalization and trading volume in a small number of issuers representing a limited number of industries, as well as a high concentration of investors and financial intermediaries. Certain Asian countries have experienced and may in the future experience expropriation and nationalization of assets, confiscatory taxation, currency manipulation, political instability, armed conflict and social instability as a result of religious, ethnic, socio-economic and/or political unrest. In particular, escalated tensions involving North Korea and any outbreak of hostilities involving North Korea could have a severe adverse effect on Asian economies. Governments of certain Asian countries have exercised, and continue to exercise, substantial influence over many aspects of the private sector. In certain cases, the government owns or controls many companies, including the largest in the country. Accordingly, government actions could have a significant effect on the issuers of the Fund’s securities or on economic conditions generally. Recent developments in relations between the U.S. and China have heightened concerns of increased tariffs and restrictions on trade between the two countries. An increase in tariffs or trade restrictions, or even the threat of such developments, could lead to a significant reduction in international trade, which could have a negative impact on the economy of Asian countries and a commensurately negative impact on the Fund.

AUTHORIZED PARTICIPANT CONCENTRATION RISK. Only an authorized participant may engage in creation or redemption transactions directly with the Fund. A limited number of institutions act as authorized participants for the Fund. To the extent that

these institutions exit the business or are unable to proceed with creation and/or redemption orders and no other authorized participant steps forward to create or redeem, the Fund’s shares may trade at a premium or discount to the Fund’s net asset value and possibly face delisting.

COUNTERPARTY RISK. Fund transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund. The Fund may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

CURRENCY RISK. Changes in currency exchange rates affect the value of investments denominated in a foreign currency, and therefore the value of such investments in the Fund’s portfolio. The Fund’s net asset value could decline if a currency to which the Fund has exposure depreciates against the U.S. dollar or if there are delays or limits on repatriation of such currency. 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.

CYBER SECURITY RISK. The Fund is susceptible to 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 issuers of securities in which the Fund invests or the Fund’s third-party service providers, such as its administrator, transfer agent, custodian, or sub-advisor, as applicable, can also subject the Fund to many of the same risks associated with direct cyber security breaches. Although the Fund has established risk management systems designed to reduce the risks associated with cyber security, 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.

DERIVATIVES RISK. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The low margin deposits normally required in trading derivatives, including futures contracts, permit a high degree of leverage. Accordingly, a relatively small price movement may result in an immediate and substantial loss. The use of leverage may also cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet collateral segregation requirements. The use of leveraged derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

DYNAMIC HEDGING RISK. Because of the Fund’s utilization of the dynamic currency hedging strategy, the Fund may have lower returns than an equivalent non-currency hedged investment when the component currencies are rising relative to the U.S. dollar. As such, contracts to sell foreign currency will generally be expected to limit any potential gain that might be realized by the Fund if the value of the hedged currency increases. In addition, the use of currency hedging will not necessarily eliminate exposure to all currency fluctuations. Hedging against a decline in the value of a currency does not eliminate fluctuations in the value of a portfolio security traded in that currency or prevent a loss if the value of the security declines. Moreover, it may not be possible for the Fund to hedge against a devaluation that is so generally anticipated that the Fund is not able to contract to sell the currency at a price above the devaluation level it anticipates.

EQUITY SECURITIES RISK. The value of the Fund’s shares will fluctuate with changes in the value of the equity securities in which it invests. 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 equity market, such as market volatility, or when political or economic events affecting an issuer occur. 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.

EUROPE RISK. The Fund is subject to certain risks specifically associated with investments in the securities of European issuers. 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. In a 2016 referendum, the United Kingdom elected to withdraw from the EU (“Brexit”). After years of negotiations between the United Kingdom and the EU, a withdrawal agreement was reached that would have the United Kingdom formally leave the EU and enter a transition period during which the United Kingdom would continue to follow all EU rules and remain a member of the EU single market and customs union. During this transition period, the United Kingdom is expected to begin negotiations with the EU on a free trade agreement. Should the transition period end without the United Kingdom and the EU agreeing on such an agreement, trade and economic relations between the two parties will be governed by World Trade Organization (“WTO”) rules. Under such a scenario, trade between the United Kingdom and the EU would no longer be tariff-free and non-tariff barriers such as new customs procedures would also arise, adding costs to doing business. As the second largest economy among EU members, the implications of the United Kingdom’s withdrawal are difficult to gauge and cannot be fully known. Its departure may negatively impact the EU and Europe as a whole by causing volatility within the EU, triggering prolonged economic downturns in certain European countries or sparking additional member states to contemplate departing the EU (thereby perpetuating political instability in the region).

FORWARD CONTRACTS RISK. A forward contract is an over-the-counter derivative transaction between two parties to buy or sell a specified amount of an underlying reference at a specified price (or rate) on a specified date in the future. Forward contracts are negotiated on an individual basis and are not standardized or traded on exchanges. The market for forward contracts is substantially unregulated and can experience lengthy periods of illiquidity, unusually high trading volume and other negative impacts, such as political intervention, which may result in volatility or disruptions in such markets. A relatively small price movement in a forward contract may result in substantial losses to the Fund, exceeding the amount of the margin paid. Forward contracts can increase the Fund’s risk exposure to underlying references and their attendant risks, such as credit risk, currency risk, market risk, and interest rate risk, while also exposing the Fund to counterparty risk, liquidity risk and valuation risk, among others.

FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS RISK. In connection with its trading in forward foreign currency contracts, the Fund will contract with a foreign or domestic bank, or a foreign or domestic securities dealer, to make or take future delivery of a specified amount of a particular currency. There are no limitations on daily price moves in such forward contracts, and banks and dealers are not required to continue to make markets in such contracts. There have been periods during which certain banks or dealers have refused to quote prices for such forward contracts or have quoted prices with an unusually wide spread between the price at which the bank or dealer is prepared to buy and that at which it is prepared to sell. Governmental imposition of credit controls might limit any such forward contract trading. Forward foreign currency exchange contracts involve certain risks, including the risk of failure of the counterparty to perform its obligations under the contract and the risk that the use of forward contracts may not serve as a complete hedge because of an imperfect correlation between movements in the prices of the contracts and the prices of the currencies hedged. Forward foreign currency exchange contracts may limit any potential gain that might result should the value of the underlying currencies increase. In addition, because forward currency exchange contracts are privately negotiated transactions, there can be no assurance that the Fund will have flexibility to roll-over a forward foreign currency exchange contract upon its expiration if it desires to do so.

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’s shares, the size of the Fund and the market volatility of the Fund. Inclusion in an index could 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 below the Fund’s net asset value during certain periods. In addition, index rebalances may potentially result in increased trading activity in the Fund’s shares.

JAPAN RISK. The Fund is subject to certain risks specifically associated with investments in the securities of Japanese issuers. The Japanese economy may be subject to considerable degrees of economic, political and social instability, which could have a negative impact on Japanese securities. Japan’s economy is characterized by government intervention and protectionism, reliance on oil imports, an unstable financial services sector and relatively high unemployment. Since 2000, Japan has experienced relatively low economic growth, and it may remain low in the future. Its economy is heavily dependent on international trade and has been adversely affected by trade tariffs and competition from emerging economies. As such, economic growth is heavily dependent on continued growth in international trade, relatively low commodities prices, government support of the financial services sector and other government policies. Any changes or trends in these economic factors could have a significant impact on Japanese markets overall and may negatively affect the Fund’s investments. Japan’s economy and equity market also share a strong correlation with U.S. markets and the Japanese economy may be affected by economic problems in the U.S. Despite a strengthening in the economic relationship between Japan and China, the countries’ political relationship has at times been strained. Should political tension increase, it could adversely affect the economy and destabilize the region as a whole. Additionally, escalated tensions involving North Korea and any outbreak of hostilities involving North Korea could have a severe adverse effect on Japan’s economy. Japan’s geography also subjects it to an increased risk of natural disasters, such as earthquakes, volcanic eruptions, typhoons and tsunamis, all of which could negatively impact the Fund’s investments.

LIQUIDITY RISK. Certain Fund investments may be subject to restrictions on resale, trade over-the-counter market or in limited volume, or lack an active trading market. Accordingly, the Fund may not be able to sell or close out of such investments at favorable times or prices (or at all), or at the prices approximating those at which the Fund currently values them. Illiquid securities may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value.

MANAGEMENT RISK. The Fund is subject to management risk because it is an actively managed portfolio. In managing the Fund’s investment portfolio, the Sub-Advisor will apply investment techniques and risk analyses that may not have the desired result. There can be no guarantee that the Fund will meet its investment objective.

The Sub-Advisor specializes in managing asset allocation portfolios, which invest in various investment vehicles, including the Fund and other exchange-traded funds (“ETFs”), to obtain targeted amounts of exposure to different asset classes. The Fund was developed to serve as, and will serve as, an investment vehicle for such asset allocation portfolios. As the manager of the Fund and the portfolios, the Sub-Advisor is likely to encounter conflicts of interest. For example, the Sub-Advisor may need to reduce its asset allocation portfolios’ exposure to an asset class to which the portfolios obtain exposure by investing in the Fund. Under such circumstances, the Sub-Advisor would liquidate some or all of the portfolios’ investments in the Fund, which could adversely affect the Fund.

MARKET MAKER RISK. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares due to a limited number of market markers. 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. The Fund 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. 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.

MARKET RISK. Market risk is the risk that a particular security, 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.

NON-U.S. SECURITIES 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, capital controls, lack of liquidity, currency exchange rates, excessive taxation, government seizure of assets, the imposition of sanctions by foreign governments, different legal or accounting standards, and less government supervision and regulation of securities exchanges in foreign countries.

PORTFOLIO TURNOVER RISK. High portfolio turnover may result in the Fund paying higher levels of transaction costs and may generate greater tax liabilities for shareholders. Portfolio turnover risk may cause the Fund’s performance to be less than expected.

PREMIUM/DISCOUNT RISK. The market price of the Fund’s shares will generally fluctuate in accordance with changes in the Fund’s 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, 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 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.

SIGNIFICANT EXPOSURE RISK. To the extent that the Fund invests 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 significant exposure makes the Fund more susceptible to any single occurrence and may subject the Fund to greater market risk than a fund that is more broadly diversified.

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, fewer 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. Further, secondary markets may be subject to irregular trading activity and wide bid-ask spreads (which may be especially pronounced for smaller funds). 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. In the event market makers cease making a market in the Fund's shares or authorized participants stop submitting purchase or redemption orders for Creation Units, Fund shares may trade at a larger premium or discount to their net asset value. 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.

UNITED KINGDOM RISK. The Fund is subject to certain risks specifically associated with investments in the securities of United Kingdom issuers. Investments in issuers located in the United Kingdom may subject the Fund to regulatory, political, currency, security and economic risk specific to the United Kingdom. The United Kingdom has one of the largest economies in Europe and is heavily dependent on trade with the European Union (“EU”), and to a lesser extent the United States and China. As a result, the economy of the United Kingdom may be impacted by changes to the economic health of EU member counties, the United States and China. In 2016, the United Kingdom voted via referendum to leave the EU (“Brexit”). After years of negotiations between the United Kingdom and the EU, a withdrawal agreement was reached that would have the United Kingdom formally leave the EU and enter a transition period during which the United Kingdom would continue to follow all EU rules and remain a member of the EU single market and customs union. During this transition period, the United Kingdom is expected to begin negotiations with the EU on a free trade agreement. Should the transition period end without the United Kingdom and the EU agreeing on such an agreement, trade and economic relations between the two parties will be governed by World Trade Organization (“WTO”) rules. Under such a scenario, trade between the United Kingdom and the EU would no longer be tariff-free and non-tariff barriers such as new customs procedures would also arise, adding costs to doing business. The precise impact on the United Kingdom’s economy as a result of its departure from the EU depends to a large degree on its ability to conclude favorable trade deals with the EU and other countries, including the United States, China, India and Japan. While new trade deals may boost economic growth, such growth may not be able to offset the increased costs of trade with the EU resulting from the United Kingdom’s loss of its membership in the EU single market. Certain sectors within the United Kingdom’s economy may be particularly affected by Brexit, including the automotive, chemicals, financial services and professional services.

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

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.

Portfolio Managers

The following persons serve as portfolio managers of the Fund.

•	Adam Grossman, CFA, Portfolio Manager of RIG
•	Chris Konstantinos, CFA, Portfolio Manager of RIG
•	Rob Glownia, CFA, Senior Portfolio Manager of RIG

Each of the portfolio managers is primarily and jointly responsible for the day-to-day management of the Fund. Each of the portfolio managers has served as part of the portfolio management team of the Fund since 2016, except Rob Glownia, who has served as a member of the portfolio management team since 2019.

Purchase and Sale of Fund Shares

The Fund issues and redeems shares on a continuous basis, at net asset value, only in Creation Units consisting of 50,000 shares. The Fund’s Creation Units are generally issued and redeemed in-kind for securities in which the Fund invests and, in certain circumstances, for cash and only to and from broker-dealers and large institutional investors that have entered into participation agreements. Individual shares of the Fund may only be purchased and sold on Nasdaq and other eligible securities exchanges through a broker-dealer. Shares of the Fund trade on Nasdaq at market prices rather than 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).

Tax Information

The Fund’s distributions are taxable and will generally be taxed as ordinary income or capital gains. Distributions on shares held in a tax-deferred account, while not immediately taxable, will be subject to tax when the shares are no longer held in a tax-deferred account.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), First Trust and First Trust Portfolios L.P., the Fund’s distributor, may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.
