NATIONWIDE RISK-BASED U.S. EQUITY ETF
Investment Objective
The Nationwide Risk-Based U.S. Equity ETF (the “Fund”) seeks to track the total return performance, before fees and expenses, of the Rothschild & Co Risk-Based US Index (the “Index”).
Fees and Expenses of the Fund
The following table describes the fees and expenses you may pay if you buy, hold, and sell shares of the Fund (“Shares”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below.
Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Management Fees 0.30%
Distribution and Service (Rule 12b-1) Fees None
Other Expenses 0.00%
Total Annual Fund Operating Expenses 0.30%
Expense Example
This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. The Example does not take into account brokerage commissions that you may pay on your purchases and sales of Shares. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
1 Year: $31 3 Years: $97 5 Years: $169 10 Years: $381
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 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. For the fiscal year ended August 31, 2021, the Fund’s portfolio turnover rate was 57% of the average value of its portfolio.
Principal Investment Strategies
The Fund uses a “passive management” (or indexing) approach to track the total return performance, before fees and expenses, of the Index.
Rothschild & Co Risk-Based US Index
The Index is a rules-based, equal risk-weighted index that is designed to provide exposure to U.S.-listed large capitalization companies with lower volatility, reduced maximum drawdown (the loss from the highest Index value to its lowest value before achieving a new highest value), and an improved Sharpe ratio (a risk-adjusted measure of return) as compared to traditional, market capitalization weighted approaches. The Index was developed in 2014 and is licensed by Rothschild & Co Risk Based Investments LLC, the Fund’s index provider.
Construction of the Index begins with the universe of equity securities that have their primary listing in the United States. The universe is then screened to keep only the top 500 equity securities by market capitalization and to eliminate securities with insufficient liquidity (average daily traded value of less than $1 million over the most recent three-month period) and equity securities that have been listed for less than one year (the remaining securities are referred to as the “Eligible Universe”).
The securities in the Eligible Universe are then subjected to a risk contribution calculation based on each security’s volatility and correlation to the other Eligible Universe securities for the most recent one-year calculation period. The securities in the Eligible Universe are then ranked based on their risk contribution, and the 50% of securities with the lowest risk contribution are selected to be included in the Index (the “Index Constituents”). To reduce turnover, Index Constituents will not be removed from the Index based on their risk contribution so long as they are within the 55% of securities with the lowest risk in the Eligible Universe.

3



The Index Constituents are then weighted by a systematic equally-weighted risk contribution model (the “Risk-Weighting Model”). The Risk-Weighting Model incorporates each Index Constituent’s volatility and correlation to the other Index Constituents for the most recent one-year calculation period to produce a portfolio where each Index Constituent contributes the same level of risk, subject to the constraint that no individual Index Constituent will have a weight that exceeds 5% of the Index. The intent of security selection by risk contribution ranking and the Risk-Weighting Model is to (i) lower the overall volatility of the Index, (ii) increase the Index’s Sharpe ratio, and (iii) reduce the Index’s maximum drawdown without negatively impacting the diversification and expected return of the Index.
The list of securities in the Eligible Universe is updated quarterly on the first Friday of each January, April, July, and October (or the previous business day if such Friday is not a business day). The Index is reconstituted (i.e., Index Constituents are added or deleted, and weights are reset based on the Risk-Weighting Model) quarterly at the close of business on the second Friday of January, April, July, and October (or the next business day if such Friday is not a business day).
The Fund’s Investment Strategy
Under normal circumstances, at least 80% of the Fund’s net assets, plus borrowings for investment purposes, will be invested in equity securities that are principally traded in the United States.
The Fund will generally use a “replication” strategy to achieve its investment objective, meaning the Fund will generally invest in all of the component securities of the Index in the same approximate proportions as in the Index. However, the Fund may use a “representative sampling” strategy, meaning it may invest in a sample of the securities in the Index whose risk, return, and other characteristics closely resemble the risk, return, and other characteristics of the Index as a whole, when the Fund’s sub-adviser believes it is in the best interests of the Fund (e.g., when replicating the Index involves practical difficulties or substantial costs, an Index constituent becomes temporarily illiquid, unavailable, or less liquid, or as a result of legal restrictions or limitations that apply to the Fund but not to the Index).
The Fund generally may invest in securities or other investments not included in the Index, but which the Fund’s sub-adviser believes will help the Fund track the Index. For example, the Fund may invest in securities that are not components of the Index to reflect various corporate actions and other changes to the Index (such as reconstitutions, additions, and deletions).
To the extent the Index concentrates (i.e., holds more than 25% of its total assets) in the securities of a particular industry or group of related industries, the Fund will concentrate its investments to approximately the same extent as the Index.
Principal Investment Risks
The principal risks of investing in the Fund are summarized below. The principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund. Some or all of these risks may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and/or ability to meet its objectives. For more information about the risks of investing in the Fund, see the section in the Fund’s Prospectus titled “Additional Information About the Funds.”
Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers. 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 the Fund and its investments. For example, the global pandemic caused by COVID-19, a novel coronavirus, and the aggressive responses taken by many governments, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines or similar restrictions, has had negative impacts, and in many cases severe impacts, on markets worldwide. The COVID-19 pandemic has caused prolonged disruptions to the normal business operations of companies around the world and the impact of such disruptions is hard to predict. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets.
ETF Risks. The Fund is an ETF, and, because of an ETF’s structure, it is exposed to the following risks:
Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process

4



creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.
Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.
Trading. Although Shares are listed for trading on NYSE Arca, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares, and this could lead to differences between the market price of the Shares and the underlying value of those Shares.
Market Capitalization Risk.
Large-Capitalization Investing. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.
Models and Data Risk. The composition of the Index is heavily dependent on proprietary quantitative models as well as information and data supplied by third parties (“Models and Data”). When Models and Data prove to be incorrect or incomplete, any decisions made in reliance thereon may lead to securities being included in or excluded from the Index that would have been excluded or included had the Models and Data been correct and complete. If the composition of the Index reflects such errors, the Fund’s portfolio can be expected to reflect the errors, too.
Passive Investment Risk. The Fund is not actively managed, and its sub-adviser would not sell shares of an equity security due to current or projected underperformance of a security, industry, or sector, unless that security is removed from the Index or the selling of shares of that security is otherwise required upon a reconstitution or rebalancing of the Index in accordance with the Index methodology.
Portfolio Turnover Risk. The Fund may trade all or a significant portion of the securities in its portfolio in connection with each rebalance and reconstitution of its Index. A high portfolio turnover rate increases transaction costs, which may increase the Fund’s expenses. Frequent trading may also cause adverse tax consequences for investors in the Fund due to an increase in short-term capital gains.
Sector Risk. To the extent the Fund invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors.
Tracking Error Risk. As with all index funds, the performance of the Fund and the Index may differ from each other for a variety of reasons. For example, the Fund incurs operating expenses and portfolio transaction costs not incurred by the Index. In addition, the Fund may not be fully invested in the securities of the Index at all times or may hold securities not included in the Index.

Performance
The following performance information indicates some of the risks of investing in the Fund. The bar chart shows the Fund’s performance for calendar years ended December 31. The table illustrates how the Fund’s average annual returns for the 1-year and since inception periods compare with those of a broad measure of market performance and the Index. The Fund’s past performance, before and after taxes, does not necessarily indicate how it will perform in the future. Updated performance information is available on the Fund’s website at www.etf.nationwide.com.
Calendar Year Total Returns
ck0001540305-20210831_g1.jpg
For the year-to-date period ended September 30, 2021, the Fund’s total return was 9.30%.
During the period shown in the bar chart, the Fund’s highest quarterly return was 21.23% for the quarter ended June 30, 2020 and the lowest quarterly return was -20.32% for the quarter ended March 31, 2020.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates during the period covered by the table above and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns shown are not relevant to investors who hold their Shares through tax-deferred arrangements such as an individual retirement account (“IRA”) or other tax-advantaged accounts.
Portfolio Management
Adviser Nationwide Fund Advisors (the “Adviser”)
Sub-Adviser Vident Investment Advisory, LLC (“VIA” or the “Sub-Adviser”)
Portfolio Managers Austin Wen, CFA, Portfolio Manager for VIA, has managed the Fund since its inception in September 2017, and Rafael Zayas, CFA, SVP, Head of Portfolio Management and Trading for VIA, has managed the Fund since June 2020.
Purchase and Sale of Shares
Shares are listed on the Exchange, and individual Shares may only be bought and sold in the secondary market through brokers at market prices, rather than NAV. Because Shares trade at market prices rather than NAV, Shares may trade at a price greater than NAV (premium) or less than NAV (discount).

6



The Fund issues and redeems Shares at NAV only in large blocks known as “Creation Units,” which only APs (typically, broker-dealers) may purchase or redeem. The Fund generally issues and redeems Creation Units in exchange for a portfolio of securities and/or a designated amount of U.S. cash.
Investors may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase Shares (bid) and the lowest price a seller is willing to accept for Shares (ask) when buying or selling Shares in the secondary market (the “bid-ask spread”). Recent information about the Fund, including its NAV, market price, premiums and discounts, and bid-ask spreads is available on the Fund’s website at www.etf.nationwide.com.
Tax Information
Fund distributions are generally taxable as ordinary income, qualified dividend income, or capital gains (or a combination), unless your investment is in an IRA or other tax-advantaged account. Distributions on investments made through tax-deferred arrangements may be taxed later upon withdrawal of assets from those accounts.
Financial Intermediary Compensation
If you purchase Shares through a broker-dealer or other financial intermediary (such as a bank) (an “Intermediary”), the Adviser or its affiliates may pay Intermediaries for certain activities related to the Fund, including participation in activities that are designed to make Intermediaries more knowledgeable about exchange traded products, including the Fund, or for other activities, such as marketing, educational training or other initiatives related to the sale or promotion of Shares. These payments may create a conflict of interest by influencing the Intermediary and your salesperson to recommend the Fund over another investment. Any such arrangements do not result in increased Fund expenses. Ask your salesperson or visit the Intermediary’s website for more information.

NATIONWIDE RISK-BASED INTERNATIONAL EQUITY ETF
Investment Objective
The Nationwide Risk-Based International Equity ETF (the “Fund”) seeks to track the total return performance, before fees and expenses, of the Rothschild & Co Risk-Based International Index (the “Index”).
Fees and Expenses of the Fund
The following table describes the fees and expenses you may pay if you buy, hold, and sell shares of the Fund (“Shares”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below.
Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Management Fees 0.42%
Distribution and Service (Rule 12b-1) Fees None
Other Expenses 0.00%
Total Annual Fund Operating Expenses 0.42%
Expense Example
This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. The Example does not take into account brokerage commissions that you may pay on your purchases and sales of Shares. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
1 Year: $43 3 Years: $135 5 Years: $235 10 Years: $530
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 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. For the fiscal year ended August 31, 2021, the Fund’s portfolio turnover rate was 66% of the average value of its portfolio.
Principal Investment Strategies
The Fund uses a “passive management” (or indexing) approach to track the total return performance, before fees and expenses, of the Index.
Rothschild & Co Risk-Based International Index
The Index is a rules-based, equal risk-weighted index that is designed to provide exposure to large capitalization companies in developed markets outside the United States and Canada with lower volatility, reduced maximum drawdown (the loss from the highest Index value to its lowest value before achieving a new highest value), and an improved Sharpe ratio (a risk-adjusted measure of return) as compared to traditional, market capitalization weighted approaches. The Index was developed in 2017 and is licensed by Rothschild & Co Risk Based Investments LLC, the Fund’s index provider.
Construction of the Index begins with the universe of equity securities that have their primary listing in the following countries: Australia, Austria, Belgium, Denmark, Finland, France, Germany, Hong Kong, Ireland, Italy, Japan, Netherlands, Norway, Portugal, Singapore, Spain, Sweden, Switzerland, and the United Kingdom. The universe is then screened to keep only the largest equity securities by market capitalization listed in each country and to eliminate securities with insufficient liquidity (average daily traded value of less than USD $1 million over the most recent three-month period) and equity securities that have been listed for less than one year (the remaining securities are referred to as the “Eligible Universe”).
The securities in the Eligible Universe are then subjected to a risk contribution calculation based on each security’s volatility and correlation to the other Eligible Universe securities for the most recent one-year calculation period. The securities in the Eligible Universe are then ranked based on their risk contribution, and the 50% of securities with the lowest risk contribution are selected to be

8



included in the Index (the “Index Constituents”). To reduce turnover, Index Constituents will not be removed from the Index based on their risk contribution so long as they are within the 55% of securities with the lowest risk in the Eligible Universe.
The Index Constituents are then weighted by a systematic equally-weighted risk contribution model (the “Risk-Weighting Model”). The Risk-Weighting Model incorporates each Index Constituent’s volatility and correlation to the other Index Constituents for the most recent one-year calculation period to produce a portfolio where each Index Constituent contributes the same level of risk, subject to the constraint that no individual Index Constituent will have a weight that exceeds 5% of the Index. The intent of the security selection by marginal risk contribution ranking and Risk-Weighting Model is to (i) lower the overall volatility of the Index, (ii) increase the Index’s Sharpe ratio, and (iii) reduce the Index’s maximum drawdown without negatively impacting the diversification and expected return of the Index.
The list of securities in the Eligible Universe is updated quarterly on the first Friday of each January, April, July, and October (or the previous business day if such Friday is not a business day). The Index is reconstituted (i.e., Index Constituents are added or deleted, and weights are reset based on the Risk-Weighting Model) quarterly at the close of business on the second Friday of January, April, July, and October (or the next business day if such Friday is not a business day). As of September 30, 2021, the Index included significant exposure to companies in Europe, including the United Kingdom, and Japan.
The Fund’s Investment Strategy
Under normal circumstances, at least 80% of the Fund’s net assets, plus borrowings for investment purposes, will be invested in equity securities that are principally traded in Europe, Australasia, or the Far East.
The Fund will generally use a “replication” strategy to achieve its investment objective, meaning the Fund will generally invest in all of the component securities of the Index in the same approximate proportions as in the Index. However, the Fund may use a “representative sampling” strategy, meaning it may invest in a sample of the securities in the Index whose risk, return, and other characteristics closely resemble the risk, return, and other characteristics of the Index as a whole, when the Fund’s sub-adviser believes it is in the best interests of the Fund (e.g., when replicating the Index involves practical difficulties or substantial costs, an Index constituent becomes temporarily illiquid, unavailable, or less liquid, or as a result of legal restrictions or limitations that apply to the Fund but not to the Index).
The Fund generally may invest in securities or other investments not included in the Index, but which the Fund’s sub-adviser believes will help the Fund track the Index. For example, the Fund may invest in securities that are not components of the Index to reflect various corporate actions and other changes to the Index (such as reconstitutions, additions, and deletions).
To the extent the Index concentrates (i.e., holds more than 25% of its total assets) in the securities of a particular industry or group of related industries, the Fund will concentrate its investments to approximately the same extent as the Index.
Principal Investment Risks
The principal risks of investing in the Fund are summarized below. The principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund. Some or all of these risks may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and/or ability to meet its objectives. For more information about the risks of investing in the Fund, see the section in the Fund’s Prospectus titled “Additional Information About the Funds.”
Currency Exchange Rate Risk. The Fund invests primarily in investments denominated in non-U.S. currencies or in securities that provide exposure to such currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of your 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.
Depositary Receipt Risk. Depositary Receipts involve risks similar to those associated with investments in foreign securities, such as changes in political or economic conditions of other countries and changes in the exchange rates of foreign currencies. Depositary Receipts listed on U.S. exchanges are issued by banks or trust companies and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares (“Underlying Shares”). When the Fund invests in Depositary Receipts as a substitute for an investment directly in the Underlying Shares, the Fund is exposed to the risk that the Depositary Receipts may not provide a return that corresponds precisely with that of the Underlying Shares.

9



Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers. 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 the Fund and its investments. For example, the global pandemic caused by COVID-19, a novel coronavirus, and the aggressive responses taken by many governments, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines or similar restrictions, has had negative impacts, and in many cases severe impacts, on markets worldwide. The COVID-19 pandemic has caused prolonged disruptions to the normal business operations of companies around the world and the impact of such disruptions is hard to predict. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets.
ETF Risks. The Fund is an ETF, and, because of an ETF’s structure, it is exposed to the following risks:
Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.
Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. Because securities held by the Fund may trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, the Fund is likely to experience premiums and discounts greater than those of domestic ETFs.
Trading. Although Shares are listed for trading on NYSE Arca, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares, and this could lead to differences between the market price of the Shares and the underlying value of those Shares.
Foreign Securities Risk. Investments in non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. For example, investments in non-U.S. securities may be subject to risk of loss due to foreign currency fluctuations or to political or economic instability. Investments in non-U.S. securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments.
Geographic Investment Risk. To the extent the Fund invests a significant portion of its assets in the securities of companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region.
Risks Related to Investing in Europe. The economies and markets of European countries are often closely connected and interdependent, and events in one country in Europe can have an adverse impact on other European countries. The Fund makes investments in securities of issuers that are domiciled in, or have significant operations in, member countries of the European Union (“EU”) that are subject to economic and monetary controls that can adversely affect the Fund’s investments. The European financial markets have experienced volatility and adverse trends in recent years and these events have adversely affected the exchange rate of the euro and may continue to significantly affect other European countries. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU

10



member country may have a significant adverse effect on the economies of EU member countries and their trading partners, including some or all of the European countries in which the Fund invests.
The UK formally exited from the EU on January 31, 2020 (known as “Brexit”), and effective December 31, 2020, the UK ended a transition period during which it continued to abide by the EU’s rules and the UK’s trade relationships with the EU were generally unchanged. Following this transition period, the impact on the UK and European economies and the broader global economy could be significant, resulting in negative impacts, such as increased volatility and illiquidity, and potentially lower economic growth of markets in the UK, Europe and globally, which may adversely affect the value of the Fund’s investments.
Risks Related to Investing in Japan. The Japanese economy may be subject to considerable degrees of economic, political and social instability, which could have a negative impact on Japanese securities. Since the year 2000, Japan’s economic growth rate has remained relatively low and it may remain low in the future. In addition, Japan is subject to the risk of natural disasters, such as earthquakes, volcanoes, typhoons and tsunamis. Additionally, decreasing U.S. imports, new trade regulations, changes in the U.S. dollar exchange rates, a recession in the United States or continued increases in foreclosure rates may have an adverse impact on the economy of Japan. Japan also has few natural resources, and any fluctuation or shortage in the commodity markets could have a negative impact on Japanese securities.
Market Capitalization Risk.
Large-Capitalization Investing. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.
Models and Data Risk. The composition of the Index is heavily dependent on proprietary quantitative models as well as information and data supplied by third parties (“Models and Data”). When Models and Data prove to be incorrect or incomplete, any decisions made in reliance thereon may lead to securities being included in or excluded from the Index that would have been excluded or included had the Models and Data been correct and complete. If the composition of the Index reflects such errors, the Fund’s portfolio can be expected to reflect the errors, too.
Passive Investment Risk. The Fund is not actively managed, and its sub-adviser would not sell shares of an equity security due to current or projected underperformance of a security, industry, or sector, unless that security is removed from the Index or the selling of shares of that security is otherwise required upon a reconstitution or rebalancing of the Index in accordance with the Index methodology.
Portfolio Turnover Risk. The Fund may trade all or a significant portion of the securities in its portfolio in connection with each rebalance and reconstitution of its Index. A high portfolio turnover rate increases transaction costs, which may increase the Fund’s expenses. Frequent trading may also cause adverse tax consequences for investors in the Fund due to an increase in short-term capital gains.
Sector Risk. To the extent the Fund invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors.
Tracking Error Risk. As with all index funds, the performance of the Fund and the Index may differ from each other for a variety of reasons. For example, the Fund incurs operating expenses and portfolio transaction costs not incurred by the Index. In addition, the Fund may not be fully invested in the securities of the Index at all times or may hold securities not included in the Index.

Purchase and Sale of Shares
Shares are listed on the Exchange, and individual Shares may only be bought and sold in the secondary market through brokers at market prices, rather than NAV. Because Shares trade at market prices rather than NAV, Shares may trade at a price greater than NAV (premium) or less than NAV (discount).

12



The Fund issues and redeems Shares at NAV only in large blocks known as “Creation Units,” which only APs (typically, broker-dealers) may purchase or redeem. The Fund generally issues and redeems Creation Units in exchange for a portfolio of securities and/or a designated amount of U.S. cash.
Investors may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase Shares (bid) and the lowest price a seller is willing to accept for Shares (ask) when buying or selling Shares in the secondary market (the “bid-ask spread”). Recent information about the Fund, including its NAV, market price, premiums and discounts, and bid-ask spreads is available on the Fund’s website at www.etf.nationwide.com
Tax Information
Fund distributions are generally taxable as ordinary income, qualified dividend income, or capital gains (or a combination), unless your investment is in an IRA or other tax-advantaged account. Distributions on investments made through tax-deferred arrangements may be taxed later upon withdrawal of assets from those accounts.
Financial Intermediary Compensation
If you purchase Shares through a broker-dealer or other financial intermediary (such as a bank) (an “Intermediary”), the Adviser or its affiliates may pay Intermediaries for certain activities related to the Fund, including participation in activities that are designed to make Intermediaries more knowledgeable about exchange traded products, including the Fund, or for other activities, such as marketing, educational training or other initiatives related to the sale or promotion of Shares. These payments may create a conflict of interest by influencing the Intermediary and your salesperson to recommend the Fund over another investment. Any such arrangements do not result in increased Fund expenses. Ask your salesperson or visit the Intermediary’s website for more information.

NATIONWIDE MAXIMUM DIVERSIFICATION U.S. CORE EQUITY ETF
Investment Objective
The Nationwide Maximum Diversification U.S. Core Equity ETF (the “Fund”) seeks to track the total return performance, before fees and expenses, of the TOBAM Maximum Diversification USA Index (the “Index”).
Fees and Expenses of the Fund
The following table describes the fees and expenses you may pay if you buy, hold, and sell shares of the Fund (“Shares”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below.
Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Management Fees 0.34%
Distribution and Service (Rule 12b-1) Fees None
Other Expenses 0.00%
Total Annual Fund Operating Expenses 0.34%
Expense Example
This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. The Example does not take into account brokerage commissions that you may pay on your purchases and sales of Shares. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
1 Year: $35 3 Years: $109 5 Years: $191 10 Years: $431
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 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. For the fiscal year ended August 31, 2021, the Fund’s portfolio turnover rate was 35% of the average value of its portfolio.
Principal Investment Strategies
The Fund uses a “passive management” (or indexing) approach to track the total return performance, before fees and expenses, of the Index.
TOBAM Maximum Diversification USA Index
The Index is a rules-based index that is designed to create a more diversified equity portfolio of the common and preferred stock of large and mid-capitalization U.S. companies relative to traditional market capitalization weighted benchmarks. The Index uses a quantitative model to weight companies in the Index universe to maximize the Diversification Ratio® of the Index, a proprietary metric based on the volatility of each Index constituent and its correlation to the other Index constituents. The Index was developed in 2011 by TOBAM S.A.S., the Fund’s index provider.
Construction of the Index begins with the universe of large and mid-capitalization common and preferred stocks of U.S. companies with a minimum market capitalization set by the Index rules and adjusted quarterly based on changes to the overall U.S. equity market capitalization. As of September 17, 2021, the minimum market capitalization for companies eligible to be added to the Index was USD $10.5 billion (USD $8.4 billion for companies already included in the Index). Companies in the Index universe are then screened to eliminate securities with insufficient liquidity and relatively new issues.
The remaining companies are then screened against a socially responsible investment (“SRI”) exclusion blacklist. The SRI exclusion blacklist contains those companies whose activities do not meet the criteria for socially responsible investing, such as the production or sale of unconventional weapons, production of tobacco, production of coal or coal-based energy, serious or systematic human rights violations, severe environmental damage, gross corruption, or other particularly serious violation of ethical norms. Companies included on the SRI exclusion blacklist are not eligible to be added to the Index, and the remaining companies constitute the “Eligible Universe” for the Index.

14



Companies in the Eligible Universe are then analyzed for their volatility and correlation to each other and weighted to maximize the Diversification Ratio®, a mathematical definition of diversification developed by TOBAM. The model used to maximize the Diversification Ratio (the “MaxDiv® Model”) seeks to lower the overall volatility of the Index while maintaining its diversification. The maximum weight for each stock is the lower of (i) 1.5% or (ii) 20 times the security’s weight had the Eligible Universe been market capitalization weighted (the “Cap-Weighted Benchmark”).
Additionally, at the time of each reconstitution of the Index, the MaxDiv Model is constrained to ensure that the “active share” of the Index, which measures how much the holdings of the Index differ from those of the securities in the Cap-Weighted Benchmark, cannot exceed 50%.
The MaxDiv Model is also optimized to reduce turnover and to limit the Index’s carbon emissions to 80% of the emissions of the Cap-Weighted Benchmark.
The Index is reconstituted (i.e., Index Constituents are added or deleted, and weights are reset based on the MaxDiv Model) quarterly after the close of business on the third Friday of each March, June, September and December using data as of the close of business on the first Friday of the relevant month.
The Fund’s Investment Strategy
Under normal circumstances, at least 80% of the Fund’s net assets, plus borrowings for investment purposes, will be invested in equity securities that are principally traded in the United States.
The Fund will generally use a “replication” strategy to achieve its investment objective, meaning the Fund will generally invest in all of the component securities of the Index in the same approximate proportions as in the Index. However, the Fund may use a “representative sampling” strategy, meaning it may invest in a sample of the securities in the Index whose risk, return, and other characteristics closely resemble the risk, return, and other characteristics of the Index as a whole, when the Fund’s sub-adviser believes it is in the best interests of the Fund (e.g., when replicating the Index involves practical difficulties or substantial costs, an Index constituent becomes temporarily illiquid, unavailable, or less liquid, or as a result of legal restrictions or limitations that apply to the Fund but not to the Index).
The Fund generally may invest in securities or other investments not included in the Index, but which the Fund’s sub-adviser believes will help the Fund track the Index. For example, the Fund may invest in securities that are not components of the Index to reflect various corporate actions and other changes to the Index (such as reconstitutions, additions, and deletions).
To the extent the Index concentrates (i.e., holds more than 25% of its total assets) in the securities of a particular industry or group of related industries, the Fund will concentrate its investments to approximately the same extent as the Index.
Principal Investment Risks
The principal risks of investing in the Fund are summarized below. The principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund. Some or all of these risks may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and/or ability to meet its objectives. For more information about the risks of investing in the Fund, see the section in the Fund’s Prospectus titled “Additional Information About the Funds.”
Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers. 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 the Fund and its investments. For example, the global pandemic caused by COVID-19, a novel coronavirus, and the aggressive responses taken by many governments, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines or similar restrictions, has had negative impacts, and in many cases severe impacts, on markets worldwide. The COVID-19 pandemic has caused prolonged disruptions to the normal business operations of companies around the world and the impact of such disruptions is hard to predict. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets.

15



ETF Risks. The Fund is an ETF, and, because of an ETF’s structure, it is exposed to the following risks:
Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.
Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.
Trading. Although Shares are listed for trading on NYSE Arca, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares, and this could lead to differences between the market price of the Shares and the underlying value of those Shares.
Market Capitalization Risk.
Large-Capitalization Investing. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.
Models and Data Risk. The composition of the Index is heavily dependent on proprietary quantitative models as well as information and data supplied by third parties (“Models and Data”). When Models and Data prove to be incorrect or incomplete, any decisions made in reliance thereon may lead to securities being included in or excluded from the Index that would have been excluded or included had the Models and Data been correct and complete. If the composition of the Index reflects such errors, the Fund’s portfolio can be expected to reflect the errors, too.
Passive Investment Risk. The Fund is not actively managed, and its sub-adviser would not sell shares of an equity security due to current or projected underperformance of a security, industry, or sector, unless that security is removed from the Index or the selling of shares of that security is otherwise required upon a reconstitution or rebalancing of the Index in accordance with the Index methodology.
Preferred Securities Risk. Preferred securities may pay fixed or adjustable rates of return and are subject to many of the risks associated with debt securities (e.g., interest rate risk, call risk and extension risk). In addition, preferred securities are subject to issuer-specific and market risks applicable generally to equity securities. Because many preferred securities allow the issuer to convert their preferred security into common stock, preferred securities are often sensitive to declining common stock values. A company’s preferred securities generally pay dividends only after the company makes required payments to holders of its bonds and other debt. For this reason, the value of preferred securities will usually react more strongly than bonds and other debt to actual or perceived changes in the company’s financial condition or prospects. Preferred securities of smaller companies may be more vulnerable to adverse developments than preferred stock of larger companies.
Sector Risk. To the extent the Fund invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors.
Socially Responsible Investment Risk. Because the methodology of the Index eliminates securities of certain issuers for non-financial reasons, the Index, and consequently the Fund, may underperform the broader equity market or other indices or funds that do not utilize similar criteria when selecting investments.
Tracking Error Risk. As with all index funds, the performance of the Fund and the Index may differ from each other for a variety of reasons. For example, the Fund incurs operating expenses and portfolio transaction costs not incurred by the Index. In

addition, the Fund may not be fully invested in the securities of the Index at all times or may hold securities not included in the Index.

NATIONWIDE NASDAQ-100 RISK-MANAGED INCOME ETF
Investment Objective
The Nationwide Nasdaq-100 Risk-Managed Income ETF (the “Fund”) seeks current income with downside protection.
Fees and Expenses of the Fund
The following table describes the fees and expenses you may pay if you buy, hold, and sell shares of the Fund (“Shares”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below.
Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Management Fees 0.68%
Distribution and/or Service (12b-1) Fees 0.00%
Other Expenses 0.00%
Total Annual Fund Operating Expenses
0.68%

Expense Example
This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. The Example does not take into account brokerage commissions that you may pay on your purchases and sales of Shares. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
1 Year: $69 3 Years: $218 5 Years: $379 10 Years: $847
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 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. This rate excludes the value of portfolio securities received or delivered as a result of in-kind creations or redemptions of the Fund’s Shares and securities, including options, whose maturities or expiration dates at the time of acquisition were one year or less. For the fiscal year ended August 31, 2021, the Fund’s portfolio turnover rate was 10% of the average value of its portfolio.
Principal Investment Strategy
The Fund is an actively-managed exchange-traded fund (“ETF”) that seeks to achieve its investment objective principally by investing in a portfolio of the stocks included in the Nasdaq-100® Index (the “Nasdaq-100” or the “Reference Index”) and an options collar (i.e., a mix of written (sold) call options and long (bought) put options) on the Nasdaq-100. The Fund seeks to generate high current income on a monthly basis from a combination of the dividends received from the Fund’s equity holdings and the premiums earned from the options collar. The options collar seeks to generate a net-credit, meaning that the premium received from the sale of the call options will be greater than the cost of buying the protective put options. The options collar is intended to reduce the Fund’s volatility and provide a measure of downside protection.
The Nasdaq-100 is a market capitalization weighted index comprised of the securities of 100 of the largest non-financial companies listed on The Nasdaq Stock Market LLC based on their market capitalization. Such securities may include companies domiciled domestically or internationally (including in emerging markets), and may include common stocks, ordinary shares, depositary receipts representing interests in non-U.S. companies, and tracking stocks. As of September 30, 2021, the Nasdaq-100 had significant exposure to companies in the information technology and communication services sectors. The Fund will concentrate its investments (i.e., hold more than 25% of its total assets) in a particular industry or group of industries to approximately the same extent that the Reference Index concentrates in an industry or group of industries.

19



The Fund will generally use a “replication” strategy to invest in the Nasdaq-100, meaning the Fund will generally invest in all of the component securities of the Nasdaq-100 in the same approximate proportions as in the Nasdaq-100. However, the Fund may use a “representative sampling” strategy, meaning it may invest in a sample of the securities in the Nasdaq-100 whose risk, return, and other characteristics closely resemble the risk, return, and other characteristics of the Nasdaq-100 as a whole, when the Fund’s sub-adviser believes it is in the best interests of the Fund (e.g., when replicating the Nasdaq-100 involves practical difficulties or substantial costs, a Nasdaq-100 constituent becomes temporarily illiquid, unavailable, or less liquid, or as a result of legal restrictions or limitations that apply to the Fund but not to the Nasdaq-100).
The Fund’s sub-adviser generally utilizes a proprietary, systematic model to manage the Fund’s options positions in an objective, rules-based manner, although the sub-adviser may actively manage the written call options prior to expiration to potentially capture gains and minimize losses due to the movement of the Nasdaq-100.
The Fund’s options collar strategy typically consists of two components: (i) selling call options on the Nasdaq-100 or another reference asset representing U.S. equity securities on up to 100% of the value of the equity securities held by the Fund to generate premium from such options, while (ii) simultaneously reinvesting a portion of such premium to buy put options on the same reference asset(s) to “hedge” or mitigate the downside risk associated with owning equity securities.
Call Options. A written (sold) call option gives the seller the obligation to sell shares of the reference asset at a specified price (“strike price”) until a specified date (“expiration date”). The writer (seller) of the call option receives an amount (premium) for writing (selling) the option. In the event the reference asset appreciates above the strike price and the holder exercises the call option, the Fund will have to pay the difference between the value of the reference asset and the strike price or deliver the reference asset (which loss is offset by the premium initially received), and in the event the reference asset declines in value, the call option may end up worthless and the Fund retains the premium. The call options written by the Fund will be collateralized by the Fund’s equity holdings at the time the Fund sells the options.
Put Options. When the Fund purchases a put option, the Fund pays an amount (premium) to acquire the right to sell shares of a reference asset at a strike price until the expiration date. In the event the reference asset declines in value below the strike price and the Fund exercises its put option, the Fund will be entitled to receive the difference between the value of the reference asset and the strike price (which gain is offset by the premium originally paid by the Fund), and in the event the reference asset closes above the strike price as of the expiration date, the put option may end up worthless and the Fund’s loss is limited to the amount of premium it paid.
The options purchased or sold by the Fund will typically have an expiration date approximately one-month from the time of purchase or sale. The Fund expects the total value of the call options and the total value of the put options to each be up to 100% of the Fund’s net assets. The Fund will use a portion of the premium received from writing call options to purchase put options. Call options written by the Fund will typically have a strike price that is at, near, or higher than the current price of the reference asset, and put options purchased by the Fund will typically have a strike price that is lower (in some cases, significantly lower) than the current price of the reference asset. In addition, both the call and put options will be traded on a national securities exchange and be settled in cash.
The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. Additionally, the Fund’s investment strategies may involve active and frequent trading resulting in high portfolio turnover.
Under normal circumstances, at least 80% of the Fund’s net assets, plus borrowings for investment purposes, will be invested in securities, or derivative instruments linked to securities, of companies that are included in the Fund’s Reference Index.
Principal Investment Risks
The principal risks of investing in the Fund are summarized below. The principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund. Some or all of these risks may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and/or ability to meet its objectives. For more information about the risks of investing in the Fund, see the section in the Fund’s Prospectus titled “Additional Information About the Funds.” 
Collared Options Strategy Risk. Writing and buying options are speculative activities and entail greater than ordinary investment risks. The Fund’s use of call and put options can lead to losses because of adverse movements in the price or value of the reference asset, which may be magnified by certain features of the options. When selling a call option, the Fund will receive a premium; however, this premium may not be enough to offset a loss incurred by the Fund if the price of the reference asset is above the strike price by an amount equal to or greater than the premium. The value of an option may be adversely affected if the market for the option becomes less liquid or smaller, and will be affected by changes in the value or yield of the option’s reference asset, an increase in interest rates, a change in the actual or perceived volatility of the stock market or the reference asset

20



and the remaining time to expiration. Additionally, the value of an option does not increase or decrease at the same rate as the reference asset.
The Fund’s use of options may reduce the Fund’s ability to profit from increases in the value of the Fund’s equity holdings. If the price of the reference asset of a written call option rises above its strike price, the value of the option and, consequently, the Fund may decline significantly more than if the Fund invested solely in the reference asset instead of using options. Similarly, if the price of the reference asset of a purchased put option remains above its strike price, the option may become worthless, and, consequently the value of the Fund may decline significantly more than if the Fund invested solely in the reference asset instead of using options.
Correlation Risk. The Fund expects to invest a portion of its assets to replicate the holdings of the Nasdaq-100, and the Fund’s sub-adviser does not expect to sell shares of an equity security due to current or projected underperformance of a security, industry, or sector, unless that security is removed from the Nasdaq-100. Although the Fund expects to invest a portion of its assets to replicate the holdings of the Nasdaq-100, the performance of such portion of the Fund and the Nasdaq-100 may differ from each other for a variety of reasons. For example, the Fund incurs operating expenses and portfolio transaction costs not incurred by the Nasdaq-100. In addition, the Fund may not be fully invested in the securities of the Nasdaq-100 at all times or may hold securities not included in the Nasdaq-100.
Currency Exchange Rate Risk. The Fund may invest in investments denominated in non-U.S. currencies or in securities that provide exposure to such currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of your 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.
Depositary Receipt Risk. American Depositary Receipts (“ADRs”) involve risks similar to those associated with investments in foreign securities and certain additional risks. ADRs listed on U.S. exchanges are issued by banks or trust companies, and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares. When the Fund invests in ADRs as a substitute for a direct investment in the underlying foreign shares, the Fund is exposed to the risk that the ADRs may not provide a return that corresponds precisely with that of the underlying foreign shares.
Derivatives Risk. The Fund invests in options that derive their performance from the performance of an underlying reference asset. Derivatives, such as the options in which the Fund invests, can be volatile and involve various types and degrees of risks, depending upon the characteristics of a particular derivative. Derivatives may have investment exposures that are greater than their cost would suggest, meaning that a small investment in a derivative could have a substantial impact on the performance of the Fund. The Fund could experience a loss if its derivatives do not perform as anticipated, the derivatives are not correlated with the performance of their reference asset, or if the Fund is unable to purchase or liquidate a position because of an illiquid secondary market. The market for many derivatives is, or suddenly can become, illiquid. Changes in liquidity may result in significant, rapid, and unpredictable changes in the prices for derivatives.
Emerging Markets Risk. The Fund may have exposure to companies domiciled or doing business in emerging markets. Emerging markets are riskier than more developed markets because they tend to develop unevenly and may never fully develop. Emerging markets may be more prone to political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, sanctions or other measures by the United States or other governments, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investments, and less stringent investor protection and disclosure standards of foreign markets. In addition, many emerging securities markets have far lower trading volumes and less liquidity than developed markets.
Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers. 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 the Fund and its investments. For example, the global pandemic caused by COVID-19, a novel coronavirus, and the aggressive responses taken by many governments, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines or similar restrictions, has had negative impacts, and in many cases severe impacts, on markets worldwide. The COVID-19 pandemic has caused prolonged disruptions to the normal business operations of companies around the world and the impact of such disruptions is hard to predict. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets.

21



ETF Risks. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:
Authorized Participants, Market Makers, and Liquidity Providers Limitation Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
Cash Redemption Risk. The Fund’s investment strategy may require it to effect redemptions, in whole or in part, for cash. As a result, the Fund may be required to sell portfolio securities to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize investment income and/or capital gains or losses that it might not have recognized if it had completely satisfied the redemption in-kind. As a result, the Fund may be less tax efficient if it includes such a cash payment than if the in-kind redemption process was used exclusively. In addition, cash redemptions may incur higher brokerage costs than in-kind redemptions and these added costs may be borne by the Fund and negatively impact Fund performance.
Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.
Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.
Trading. Although Shares are listed for trading on a national securities exchange, such as the NYSE Arca, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares.
Foreign Investment Risk. Because of the Fund’s investment in non-U.S. companies, changes in foreign economies and political climates are more likely to affect the Fund than a fund that invests exclusively in U.S. companies. There may be less government supervision of foreign markets, resulting in non-uniform accounting practices and less publicly available information. The value of foreign investments may be affected by changes in exchange control regulations, application of foreign tax laws (including withholding tax), changes in governmental administration or economic or monetary policy (in this country or abroad) or changed circumstances in dealings between nations.
High Portfolio Turnover Risk. The Fund may frequently buy and sell portfolio securities and other assets to rebalance the Fund’s exposure to various market sectors. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause the Fund’s performance to be less than you expect.
Industry Exposure Risk. From time to time, the Fund may invest a significant percentage of its assets in issuers in a single industry (or the same group of industries). To the extent the Fund’s investments are concentrated in or have significant exposure to a particular issuer, industry, or group of industries, the Fund may be more vulnerable to adverse events affecting such issuer, industry, or group of industries than if the Fund’s investments were more broadly diversified. The Fund’s industry exposure is expected to vary over time based on the composition of the Reference Index.
Limited Operating History. The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.
Management Risk. The Fund is actively-managed and may or may not meet its investment objective based on the portfolio managers’ success or failure to implement investment strategies for the Fund.
Market Capitalization Risk.
Large-Capitalization Investing. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.

22



Model and Data Risk. The sub-adviser will make use of quantitative models and information and data supplied by third parties to, among other things, help determine the strike prices of the Fund’s options positions. To the extent the models used by the sub-adviser or the information and data supplied by third parties are incorrect or incomplete, the decisions made by the sub-adviser in reliance thereon will expose the Fund to potential risks and could lead to the Fund incurring losses on its investments.
Non-Diversification Risk. Although the Fund intends to invest in a variety of securities and instruments, the Fund will be considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance. However, the Fund intends to satisfy the diversification requirements for qualifying as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”).
Sector Risk. To the extent the Fund invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors.
Communications Services Sector Risk. Communications services companies are subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals, or the enactment of new adverse regulatory requirements may adversely affect the business of such companies. Companies in the communications services sector can also be significantly affected by intense competition, including competition with alternative technologies such as wireless communications (including with 5G and other technologies), product compatibility, consumer preferences, rapid product obsolescence, and research and development of new products. Technological innovations may make the products and services of such companies obsolete.
Information Technology Sector Risk. Market or economic factors impacting information technology companies and companies that rely heavily on technological advances could have a significant effect on the value of the Fund’s investments. The value of stocks of information technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Information technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability.
Tax Risk. The Fund expects to generate premiums from its sale of call options. These options are expected to result in capital gains or losses for federal income tax purposes and may be subject to mark-to-market rules. These gains or losses will be wholly or partly long-term or short-term depending on the nature of the options sold by the Fund and will take into account premiums generated. In addition, stocks that are hedged with put options may not be eligible for long-term capital gains tax treatment. If positions held by the Fund were treated as “straddles” for federal income tax purposes, or the Fund’s risk of loss with respect to a position was otherwise diminished as set forth in Treasury Regulations, dividends on stocks that are a part of such positions would not constitute qualified dividend income subject to such favorable income tax treatment and would not be eligible for the dividends received deduction for corporate shareholders. In addition, generally, straddles are subject to certain rules that may affect the amount, character and timing of the Fund’s gains and losses with respect to straddle positions. The Fund is not designed for investors seeking a tax efficient investment.
Tracking Stock Risk. Tracking stock is a separate class of common stock designed to “track” the performance of a specific unit or operating division within a larger company. As a result, a tracking stock’s value may decline even if the common stock of the larger company increases in value. Tracking stocks share many of the same investing risks as common stocks, but the holders of tracking stock may not share the same rights as holders of a company’s common stock.

Curt Brockelman, Managing Partner, Co-Founder, and Chief Risk Officer at Harvest, has managed the Fund since December 2020, and Troy Cates, Managing Director and Portfolio Manager at Harvest, and Garrett Paolella, Managing Director and Portfolio Manager at Harvest, have managed the Fund since its inception in December 2019.
Purchase and Sale of Shares
Shares are listed on the Exchange, and individual Shares may only be bought and sold in the secondary market through brokers at market prices, rather than NAV. Because Shares trade at market prices rather than NAV, Shares may trade at a price greater than NAV (premium) or less than NAV (discount).

24



The Fund issues and redeems Shares at NAV only in large blocks known as “Creation Units,” which only APs (typically, broker-dealers) may purchase or redeem. The Fund generally issues and redeems Creation Units in exchange for a portfolio of securities and/or a designated amount of U.S. cash.
Investors may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase Shares (bid) and the lowest price a seller is willing to accept for Shares (ask) when buying or selling Shares in the secondary market (the “bid-ask spread”). Recent information about the Fund, including its NAV, market price, premiums and discounts, and bid-ask spreads is available on the Fund’s website at www.etf.nationwide.com
Tax Information
Fund distributions are generally taxable as ordinary income, qualified dividend income, or capital gains (or a combination), unless your investment is in an individual retirement account (“IRA”) or other tax-advantaged account. Distributions on investments made through tax-deferred arrangements may be taxed later upon withdrawal of assets from those accounts.
Financial Intermediary Compensation
If you purchase Shares through a broker-dealer or other financial intermediary (such as a bank) (an “Intermediary”), the Adviser or its affiliates may pay Intermediaries for certain activities related to the Fund, including participation in activities that are designed to make Intermediaries more knowledgeable about exchange traded products, including the Fund, or for other activities, such as marketing, educational training or other initiatives related to the sale or promotion of Shares. These payments may create a conflict of interest by influencing the Intermediary and your salesperson to recommend the Fund over another investment. Any such arrangements do not result in increased Fund expenses. Ask your salesperson or visit the Intermediary’s website for more information.

NATIONWIDE S&P 500 RISK-MANAGED INCOME ETF
Investment Objective
The Nationwide S&P 500 Risk-Managed Income ETF (the “Fund”) seeks current income with downside protection.
Fees and Expenses of the Fund
The following table describes the fees and expenses you may pay if you buy, hold, and sell shares of the Fund (“Shares”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below.
Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Management Fees 0.68%
Distribution and/or Service (12b-1) Fees 0.00%
Other Expenses* 0.00%
Total Annual Fund Operating Expenses
0.68%

*Estimated for the current fiscal year.
Expense Example
This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. The Example does not take into account brokerage commissions that you may pay on your purchases and sales of Shares. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
1 Year: $69 3 Years: $218
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 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. Because the Fund is newly organized, portfolio turnover information is not yet available.
Principal Investment Strategy
The Fund is an actively-managed exchange-traded fund (“ETF”) that seeks to achieve its investment objective principally by investing in a portfolio of the stocks included in the S&P 500® Index (the “S&P 500” or the “Reference Index”) and an options collar (i.e., a mix of written (sold) call options and long (bought) put options) on the S&P 500. The Fund seeks to generate high current income on a monthly basis from a combination of the dividends received from the Fund’s equity holdings and the premiums earned from the options collar. The options collar seeks to generate a net-credit, meaning that the premium received from the sale of the call options will be greater than the cost of buying the protective put options. The options collar is intended to reduce the Fund’s volatility and provide a measure of downside protection.
The S&P 500 consists of approximately 500 leading U.S.-listed companies representing approximately 80% of the U.S. equity market capitalization. As of October 29, 2021, the S&P 500 had significant exposure to companies in the information technology sector. The Fund will concentrate its investments (i.e., hold more than 25% of its total assets) in a particular industry or group of industries to approximately the same extent that the Reference Index concentrates in an industry or group of industries.
The Fund will generally use a “replication” strategy to invest in the S&P 500, meaning the Fund will generally invest in all of the component securities of the S&P 500 in the same approximate proportions as in the S&P 500. However, the Fund may use a “representative sampling” strategy, meaning it may invest in a sample of the securities in the S&P 500 whose risk, return, and other characteristics closely resemble the risk, return, and other characteristics of the S&P 500 as a whole, when the Fund’s sub-adviser believes it is in the best interest of the Fund (e.g., when replicating the S&P 500 involves practical difficulties or substantial costs, a S&P 500 constituent becomes temporarily illiquid, unavailable, or less liquid, or as a result of legal restrictions or limitations that apply to the Fund but not to the S&P 500).

26



The Fund’s sub-adviser generally utilizes a proprietary, systematic model to manage the Fund’s options positions in an objective, rules-based manner, although the sub-adviser may actively manage the written call options prior to expiration to potentially capture gains and minimize losses due to the movement of the S&P 500.
The Fund’s options collar strategy typically consists of two components: (i) selling call options on the S&P 500 or another reference asset representing U.S. equity securities on up to 100% of the value of the equity securities held by the Fund to generate premium from such options, while (ii) simultaneously reinvesting a portion of such premium to buy put options on the same reference asset(s) to “hedge” or mitigate the downside risk associated with owning equity securities.
Call Options. A written (sold) call option gives the seller the obligation to sell shares of the reference asset at a specified price (“strike price”) until a specified date (“expiration date”). The writer (seller) of the call option receives an amount (premium) for writing (selling) the option. In the event the reference asset appreciates above the strike price and the holder exercises the call option, the Fund will have to pay the difference between the value of the reference asset and the strike price or deliver the reference asset (which loss is offset by the premium initially received), and in the event the reference asset declines in value, the call option may end up worthless and the Fund retains the premium. The call options written by the Fund will be collateralized by the Fund’s equity holdings at the time the Fund sells the options.
Put Options. When the Fund purchases a put option, the Fund pays an amount (premium) to acquire the right to sell shares of a reference asset at a strike price until the expiration date. In the event the reference asset declines in value below the strike price and the Fund exercises its put option, the Fund will be entitled to receive the difference between the value of the reference asset and the strike price (which gain is offset by the premium originally paid by the Fund), and in the event the reference asset closes above the strike price as of the expiration date, the put option may end up worthless and the Fund’s loss is limited to the amount of premium it paid.
The options purchased or sold by the Fund will typically have an expiration date approximately one-month from the time of purchase or sale. The Fund expects the total value of the call options and the total value of the put options to each be up to 100% of the Fund’s net assets. The Fund will use a portion of the premium received from writing call options to purchase put options. Call options written by the Fund will typically have a strike price that is at, near, or higher than the current price of the reference asset, and put options purchased by the Fund will typically have a strike price that is lower (in some cases, significantly lower) than the current price of the reference asset. In addition, both the call and put options will be traded on a national securities exchange and be settled in cash.
The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. Additionally, the Fund’s investment strategies may involve active and frequent trading resulting in high portfolio turnover.
Under normal circumstances, at least 80% of the Fund’s net assets, plus borrowings for investment purposes, will be invested in securities, or derivative instruments linked to securities, of companies that are included in the Fund’s Reference Index.
Principal Investment Risks
The principal risks of investing in the Fund are summarized below. The principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund. Some or all of these risks may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and/or ability to meet its objectives. For more information about the risks of investing in the Fund, see the section in the Fund’s Prospectus titled “Additional Information About the Fund.”
Collared Options Strategy Risk. Writing and buying options are speculative activities and entail greater than ordinary investment risks. The Fund’s use of call and put options can lead to losses because of adverse movements in the price or value of the reference asset, which may be magnified by certain features of the options. When selling a call option, the Fund will receive a premium; however, this premium may not be enough to offset a loss incurred by the Fund if the price of the reference asset is above the strike price by an amount equal to or greater than the premium. The value of an option may be adversely affected if the market for the option becomes less liquid or smaller, and will be affected by changes in the value or yield of the option’s reference asset, an increase in interest rates, a change in the actual or perceived volatility of the stock market or the reference asset and the remaining time to expiration. Additionally, the value of an option does not increase or decrease at the same rate as the reference asset.

27



The Fund’s use of options may reduce the Fund’s ability to profit from increases in the value of the Fund’s equity holdings. If the price of the reference asset of a written call option rises above its strike price, the value of the option and, consequently, the Fund may decline significantly more than if the Fund invested solely in the reference asset instead of using options. Similarly, if the price of the reference asset of a purchased put option remains above its strike price, the option may become worthless, and, consequently the value of the Fund may decline significantly more than if the Fund invested solely in the reference asset instead of using options.
Correlation Risk. The Fund expects to invest a portion of its assets to replicate the holdings of the S&P 500, and the Fund’s sub-adviser does not expect to sell shares of an equity security due to current or projected underperformance of a security, industry, or sector, unless that security is removed from the S&P 500. Although the Fund expects to invest a portion of its assets to replicate the holdings of the S&P 500, the performance of such portion of the Fund and the S&P 500 may differ from each other for a variety of reasons. For example, the Fund incurs operating expenses and portfolio transaction costs not incurred by the S&P 500. In addition, the Fund may not be fully invested in the securities of the S&P 500 at all times or may hold securities not included in the S&P 500.
Derivative Securities Risks. The Fund invests in options that derive their performance from the performance of an underlying equity security. Derivatives, such as the options in which the Fund invests, can be volatile and involve various types and degrees of risks, depending upon the characteristics of a particular derivative. Derivatives may entail investment exposures that are greater than their cost would suggest, meaning that a small investment in a derivative could have a substantial impact on the performance of the Fund. The Fund could experience a loss if its derivatives do not perform as anticipated, the derivatives are not correlated with the performance of their underlying security, or if the Fund is unable to purchase or liquidate a position because of an illiquid secondary market. The market for many derivatives is, or suddenly can become, illiquid. Changes in liquidity may result in significant, rapid, and unpredictable changes in the prices for derivatives.
Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers. 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 the Fund and its investments. For example, the global pandemic caused by COVID-19, a novel coronavirus, and the aggressive responses taken by many governments, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines or similar restrictions, has had negative impacts, and in many cases severe impacts, on markets worldwide. The COVID-19 pandemic has caused prolonged disruptions to the normal business operations of companies around the world and the impact of such disruptions is hard to predict. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets.
ETF Risks. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:
Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
Cash Redemption Risk. The Fund’s investment strategy may require it to redeem shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.
Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.
Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to

28



supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.
Trading. Although Shares are listed for trading on NYSE Arca, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares, and this could lead to differences between the market price of the Shares and the underlying value of those Shares.
High Portfolio Turnover Risk. The Fund may frequently buy and sell portfolio securities and other assets to rebalance the Fund’s exposure to specific securities. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause the Fund’s performance to be less than you expect.
Industry Exposure Risk. From time to time, the Fund may invest a significant percentage of its assets in issuers in a single industry (or the same group of industries). To the extent the Fund’s investments are concentrated in or have significant exposure to a particular issuer, industry, or group of industries, the Fund may be more vulnerable to adverse events affecting such issuer, industry, or group of industries than if the Fund’s investments were more broadly diversified. The Fund’s industry exposure is expected to vary over time based on the composition of the Reference Index.
Management Risk. The Fund is actively-managed and may or may not meet its investment objective based on the portfolio managers’ success or failure to implement investment strategies for the Fund.
Market Capitalization Risk.
Large-Capitalization Investing. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.
Model and Data Risk. The sub-adviser will make use of quantitative models and information and data supplied by third parties to, among other things, help determine the strike prices of the Fund’s options positions. To the extent the models used by the sub-adviser or the information and data supplied by third parties are incorrect or incomplete, the decisions made by the sub-adviser in reliance thereon will expose the Fund to potential risks and could lead to the Fund incurring losses on its investments.
New Fund Risk. The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.
Non-Diversification Risk. The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance. However, the Fund intends to satisfy the diversification requirements for qualifying as a RIC under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”).
Sector Risk. To the extent the Fund invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors.
Information Technology Sector Risk. Market or economic factors impacting information technology companies and companies that rely heavily on technological advances could have a significant effect on the value of the Fund’s investments. The value of stocks of information technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Stocks of information technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Information technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability.

29



Tax Risk. The Fund expects to generate premiums from its sale of call options. These options are expected to result in capital gains or losses for federal income tax purposes and may be subject to mark-to-market rules. These gains or losses will be wholly or partly long-term or short-term depending on the nature of the options sold by the Fund and will take into account premiums generated. In addition, stocks that are hedged with put options may not be eligible for long-term capital gains tax treatment. If positions held by the Fund were treated as “straddles” for federal income tax purposes, or the Fund’s risk of loss with respect to a position was otherwise diminished as set forth in Treasury Regulations, dividends on stocks that are a part of such positions would not constitute qualified dividend income subject to such favorable income tax treatment and would not be eligible for the dividends received deduction for corporate shareholders. In addition, generally, straddles are subject to certain rules that may affect the amount, character and timing of the Fund’s gains and losses with respect to straddle positions. The Fund is not designed for investors seeking a tax efficient investment.
Tracking Stock Risk. Tracking stock is a separate class of common stock designed to “track” the performance of a specific unit or operating division within a larger company. As a result, a tracking stock’s value may decline even if the common stock of the larger company increases in value. Tracking stocks share many of the same investing risks as common stocks, but the holders of tracking stock may not share the same rights as holders of a company’s common stock.
Performance
The Fund is new and therefore does not have a performance history for a full calendar year. In the future, performance information for the Fund will be presented in this section. Updated performance information is also available on the Fund’s website at www.etf.nationwide.com.

Portfolio Managers

Curt Brockelman, Managing Partner, Co-Founder, Portfolio Manager, and Chief Risk Officer at Harvest, Troy Cates, Managing Director and Portfolio Manager at Harvest, and Garrett Paolella, Managing Director and Portfolio Manager at Harvest, have managed the Fund since its inception in December 2021.
Purchase and Sale of Shares
Shares are listed on the Exchange, and individual Shares may only be bought and sold in the secondary market through brokers at market prices, rather than NAV. Because Shares trade at market prices rather than NAV, Shares may trade at a price greater than NAV (premium) or less than NAV (discount).
The Fund issues and redeems Shares at NAV only in large blocks known as “Creation Units,” which only APs (typically, broker-dealers) may purchase or redeem. The Fund generally issues and redeems Creation Units in exchange for a portfolio of securities and/or a designated amount of U.S. cash.
Investors may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase Shares (bid) and the lowest price a seller is willing to accept for Shares (ask) when buying or selling Shares in the secondary market (the “bid-ask spread”). Recent information about the Fund, including its NAV, market price, premiums and discounts, and bid-ask spreads is available on the Fund’s website at www.etf.nationwide.com
Tax Information
Fund distributions are generally taxable as ordinary income, qualified dividend income, or capital gains (or a combination), unless your investment is in an individual retirement account (“IRA”) or other tax-advantaged account. Distributions on investments made through tax-deferred arrangements may be taxed later upon withdrawal of assets from those accounts.
Financial Intermediary Compensation
If you purchase Shares through a broker-dealer or other financial intermediary (such as a bank) (an “Intermediary”), the Adviser or its affiliates may pay Intermediaries for certain activities related to the Fund, including participation in activities that are designed to make Intermediaries more knowledgeable about exchange traded products, including the Fund, or for other activities, such as marketing, educational training or other initiatives related to the sale or promotion of Shares. These payments may create a conflict of interest by influencing the Intermediary and your salesperson to recommend the Fund over another investment. Any such arrangements do not result in increased Fund expenses. Ask your salesperson or visit the Intermediary’s website for more information.

NATIONWIDE DOW JONES RISK-MANAGED INCOME ETF
Investment Objective
The Nationwide Dow Jones Risk-Managed Income ETF (the “Fund”) seeks current income with downside protection.
Fees and Expenses of the Fund
The following table describes the fees and expenses you may pay if you buy, hold, and sell shares of the Fund (“Shares”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below.
Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Management Fees 0.68%
Distribution and/or Service (12b-1) Fees 0.00%
Other Expenses* 0.00%
Total Annual Fund Operating Expenses
0.68%

*Estimated for the current fiscal year.
Expense Example
This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. The Example does not take into account brokerage commissions that you may pay on your purchases and sales of Shares. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
1 Year: $69 3 Years: $218
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 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. Because the Fund is newly organized, portfolio turnover information is not yet available.
Principal Investment Strategy
The Fund is an actively-managed exchange-traded fund (“ETF”) that seeks to achieve its investment objective principally by investing in a portfolio of the stocks included in the Dow Jones Industrial Average® (the “Dow Jones” or the “Reference Index”) and an options collar (i.e., a mix of written (sold) call options and long (bought) put options) on the Dow Jones. The Fund seeks to generate high current income on a monthly basis from a combination of the dividends received from the Fund’s equity holdings and the premiums earned from the options collar. The options collar seeks to generate a net-credit, meaning that the premium received from the sale of the call options will be greater than the cost of buying the protective put options. The options collar is intended to reduce the Fund’s volatility and provide a measure of downside protection.
The Dow Jones is a price-weighted index comprised of the stocks of 30 U.S. blue-chip companies (i.e., well-known, established companies). As of October 29, 2021, the Dow Jones had significant exposure to companies in the information technology, health care and financial sectors. The Fund will concentrate its investments (i.e., hold more than 25% of its total assets) in a particular industry or group of industries to approximately the same extent that the Reference Index concentrates in an industry or group of industries.
The Fund will generally use a “replication” strategy to invest in the Dow Jones, meaning the Fund will generally invest in all of the component securities of the Dow Jones in the same approximate proportions as in the Dow Jones. However, the Fund may use a “representative sampling” strategy, meaning it may invest in a sample of the securities in the Dow Jones whose risk, return, and other characteristics closely resemble the risk, return, and other characteristics of the Dow Jones as a whole, when the Fund’s sub-adviser believes it is in the best interest of the Fund (e.g., when replicating the Dow Jones involves practical difficulties or substantial costs, a Dow Jones constituent becomes temporarily illiquid, unavailable, or less liquid, or as a result of legal restrictions or limitations that apply to the Fund but not to the Dow Jones).

31



The Fund’s sub-adviser generally utilizes a proprietary, systematic model to manage the Fund’s options positions in an objective, rules-based manner, although the sub-adviser may actively manage the written call options prior to expiration to potentially capture gains and minimize losses due to the movement of the Dow Jones.
The Fund’s options collar strategy typically consists of two components: (i) selling call options on the Dow Jones or another reference asset representing U.S. equity securities on up to 100% of the value of the equity securities held by the Fund to generate premium from such options, while (ii) simultaneously reinvesting a portion of such premium to buy put options on the same reference asset(s) to “hedge” or mitigate the downside risk associated with owning equity securities.
Call Options. A written (sold) call option gives the seller the obligation to sell shares of the reference asset at a specified price (“strike price”) until a specified date (“expiration date”). The writer (seller) of the call option receives an amount (premium) for writing (selling) the option. In the event the reference asset appreciates above the strike price and the holder exercises the call option, the Fund will have to pay the difference between the value of the reference asset and the strike price or deliver the reference asset (which loss is offset by the premium initially received), and in the event the reference asset declines in value, the call option may end up worthless and the Fund retains the premium. The call options written by the Fund will be collateralized by the Fund’s equity holdings at the time the Fund sells the options.
Put Options. When the Fund purchases a put option, the Fund pays an amount (premium) to acquire the right to sell shares of a reference asset at a strike price until the expiration date. In the event the reference asset declines in value below the strike price and the Fund exercises its put option, the Fund will be entitled to receive the difference between the value of the reference asset and the strike price (which gain is offset by the premium originally paid by the Fund), and in the event the reference asset closes above the strike price as of the expiration date, the put option may end up worthless and the Fund’s loss is limited to the amount of premium it paid.
The options purchased or sold by the Fund will typically have an expiration date approximately one-month from the time of purchase or sale. The Fund expects the total value of the call options and the total value of the put options to each be up to 100% of the Fund’s net assets. The Fund will use a portion of the premium received from writing call options to purchase put options. Call options written by the Fund will typically have a strike price that is at, near, or higher than the current price of the reference asset, and put options purchased by the Fund will typically have a strike price that is lower (in some cases, significantly lower) than the current price of the reference asset. In addition, both the call and put options will be traded on a national securities exchange and be settled in cash.
The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. Additionally, the Fund’s investment strategies may involve active and frequent trading resulting in high portfolio turnover.
Under normal circumstances, at least 80% of the Fund’s net assets, plus borrowings for investment purposes, will be invested in securities, or derivative instruments linked to securities, of companies that are included in the Fund’s Reference Index.
Principal Investment Risks
The principal risks of investing in the Fund are summarized below. The principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund. Some or all of these risks may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and/or ability to meet its objectives. For more information about the risks of investing in the Fund, see the section in the Fund’s Prospectus titled “Additional Information About the Fund.”
Collared Options Strategy Risk. Writing and buying options are speculative activities and entail greater than ordinary investment risks. The Fund’s use of call and put options can lead to losses because of adverse movements in the price or value of the reference asset, which may be magnified by certain features of the options. When selling a call option, the Fund will receive a premium; however, this premium may not be enough to offset a loss incurred by the Fund if the price of the reference asset is above the strike price by an amount equal to or greater than the premium. The value of an option may be adversely affected if the market for the option becomes less liquid or smaller, and will be affected by changes in the value or yield of the option’s reference asset, an increase in interest rates, a change in the actual or perceived volatility of the stock market or the reference asset and the remaining time to expiration. Additionally, the value of an option does not increase or decrease at the same rate as the reference asset.
The Fund’s use of options may reduce the Fund’s ability to profit from increases in the value of the Fund’s equity holdings. If the price of the reference asset of a written call option rises above its strike price, the value of the option and, consequently, the Fund may decline significantly more than if the Fund invested solely in the reference asset instead of using options. Similarly, if the price of the reference asset of a purchased put option remains above its strike price, the option may

32



become worthless, and, consequently the value of the Fund may decline significantly more than if the Fund invested solely in the reference asset instead of using options.
Correlation Risk. The Fund expects to invest a portion of its assets to replicate the holdings of the Dow Jones, and the Fund’s sub-adviser does not expect to sell shares of an equity security due to current or projected underperformance of a security, industry, or sector, unless that security is removed from the Dow Jones. Although the Fund expects to invest a portion of its assets to replicate the holdings of the Dow Jones, the performance of such portion of the Fund and the Dow Jones may differ from each other for a variety of reasons. For example, the Fund incurs operating expenses and portfolio transaction costs not incurred by the Dow Jones. In addition, the Fund may not be fully invested in the securities of the Dow Jones at all times or may hold securities not included in the Dow Jones.
Derivative Securities Risks. The Fund invests in options that derive their performance from the performance of an underlying equity security. Derivatives, such as the options in which the Fund invests, can be volatile and involve various types and degrees of risks, depending upon the characteristics of a particular derivative. Derivatives may entail investment exposures that are greater than their cost would suggest, meaning that a small investment in a derivative could have a substantial impact on the performance of the Fund. The Fund could experience a loss if its derivatives do not perform as anticipated, the derivatives are not correlated with the performance of their underlying security, or if the Fund is unable to purchase or liquidate a position because of an illiquid secondary market. The market for many derivatives is, or suddenly can become, illiquid. Changes in liquidity may result in significant, rapid, and unpredictable changes in the prices for derivatives.
Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers. 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 the Fund and its investments. For example, the global pandemic caused by COVID-19, a novel coronavirus, and the aggressive responses taken by many governments, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines or similar restrictions, has had negative impacts, and in many cases severe impacts, on markets worldwide. The COVID-19 pandemic has caused prolonged disruptions to the normal business operations of companies around the world and the impact of such disruptions is hard to predict. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets.
ETF Risks. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:
Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
Cash Redemption Risk. The Fund’s investment strategy may require it to redeem shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.
Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.
Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.

33



Trading. Although Shares are listed for trading on NYSE Arca, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares, and this could lead to differences between the market price of the Shares and the underlying value of those Shares.
High Portfolio Turnover Risk. The Fund may frequently buy and sell portfolio securities and other assets to rebalance the Fund’s exposure to specific securities. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause the Fund’s performance to be less than you expect.
Industry Exposure Risk. From time to time, the Fund may invest a significant percentage of its assets in issuers in a single industry (or the same group of industries). To the extent the Fund’s investments are concentrated in or have significant exposure to a particular issuer, industry, or group of industries, the Fund may be more vulnerable to adverse events affecting such issuer, industry, or group of industries than if the Fund’s investments were more broadly diversified. The Fund’s industry exposure is expected to vary over time based on the composition of the Reference Index.
Management Risk. The Fund is actively-managed and may or may not meet its investment objective based on the portfolio managers’ success or failure to implement investment strategies for the Fund.
Market Capitalization Risk.
Large-Capitalization Investing. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.
Model and Data Risk. The sub-adviser will make use of quantitative models and information and data supplied by third parties to, among other things, help determine the strike prices of the Fund’s options positions. To the extent the models used by the sub-adviser or the information and data supplied by third parties are incorrect or incomplete, the decisions made by the sub-adviser in reliance thereon will expose the Fund to potential risks and could lead to the Fund incurring losses on its investments.
New Fund Risk. The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.
Non-Diversification Risk. The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance. However, the Fund intends to satisfy the diversification requirements for qualifying as a RIC under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”).
Sector Risk. To the extent the Fund invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors.
Financial Sector Risk. This sector can be significantly affected by changes in interest rates, government regulation, the rate of defaults on corporate, consumer and government debt, the availability and cost of capital, and fallout from the housing and sub-prime mortgage crisis. Insurance companies, in particular, may be significantly affected by changes in interest rates, catastrophic events, price and market competition, the imposition of premium rate caps, or other changes in government regulation or tax law and/or rate regulation, which may have an adverse impact on their profitability. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted. In recent years, cyber attacks and technology malfunctions and failures have become increasingly frequent in this sector and have caused significant losses.
Health Care Sector Risk. Companies in the health care sector are subject to extensive government regulation and their profitability can be significantly affected by restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure (including price discounting), limited product lines, an increased emphasis on the delivery of healthcare through outpatient services, loss or impairment of intellectual property rights and litigation regarding product or service liability.
Information Technology Sector Risk. Market or economic factors impacting information technology companies and companies that rely heavily on technological advances could have a significant effect on the value of the Fund’s

34



investments. The value of stocks of information technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Stocks of information technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Information technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability.
Tax Risk. The Fund expects to generate premiums from its sale of call options. These options are expected to result in capital gains or losses for federal income tax purposes and may be subject to mark-to-market rules. These gains or losses will be wholly or partly long-term or short-term depending on the nature of the options sold by the Fund and will take into account premiums generated. In addition, stocks that are hedged with put options may not be eligible for long-term capital gains tax treatment. If positions held by the Fund were treated as “straddles” for federal income tax purposes, or the Fund’s risk of loss with respect to a position was otherwise diminished as set forth in Treasury Regulations, dividends on stocks that are a part of such positions would not constitute qualified dividend income subject to such favorable income tax treatment and would not be eligible for the dividends received deduction for corporate shareholders. In addition, generally, straddles are subject to certain rules that may affect the amount, character and timing of the Fund’s gains and losses with respect to straddle positions. The Fund is not designed for investors seeking a tax efficient investment.
Tracking Stock Risk. Tracking stock is a separate class of common stock designed to “track” the performance of a specific unit or operating division within a larger company. As a result, a tracking stock’s value may decline even if the common stock of the larger company increases in value. Tracking stocks share many of the same investing risks as common stocks, but the holders of tracking stock may not share the same rights as holders of a company’s common stock.

Financial Intermediary Compensation

NATIONWIDE RUSSELL 2000 RISK-MANAGED INCOME ETF
Investment Objective
The Nationwide Russell 2000 Risk-Managed Income ETF (the “Fund”) seeks current income with downside protection.
Fees and Expenses of the Fund
The following table describes the fees and expenses you may pay if you buy, hold, and sell shares of the Fund (“Shares”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below.
Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Management Fees 0.68%
Distribution and/or Service (12b-1) Fees 0.00%
Other Expenses* 0.00%
Total Annual Fund Operating Expenses
0.68%

*Estimated for the current fiscal year.
Expense Example
This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. The Example does not take into account brokerage commissions that you may pay on your purchases and sales of Shares. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
1 Year: $69 3 Years: $218
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 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. Because the Fund is newly organized, portfolio turnover information is not yet available.
Principal Investment Strategy
The Fund is an actively-managed exchange-traded fund (“ETF”) that seeks to achieve its investment objective principally by investing in a portfolio of the stocks included in the Russell 2000® Index (the “Russell 2000” or the “Reference Index") and an options collar (i.e., a mix of written (sold) call options and long (bought) put options) on the Russell 2000. The Fund seeks to generate high current income on a monthly basis from a combination of the dividends received from the Fund’s equity holdings and the premiums earned from the options collar. The options collar seeks to generate a net-credit, meaning that the premium received from the sale of the call options will be greater than the cost of buying the protective put options. The options collar is intended to reduce the Fund’s volatility and provide a measure of downside protection.
The Russell 2000 measures the performance of approximately 2,000 U.S. small capitalization companies. As of September 30, 2021, the Russell 2000 had significant exposure to companies in the health care sector. The Fund will concentrate its investments (i.e., hold more than 25% of its total assets) in a particular industry or group of industries to approximately the same extent that the Reference Index concentrates in an industry or group of industries.
The Fund will generally use a “replication” strategy to invest in the Russell 2000, meaning the Fund will generally invest in all of the component securities of the Russell 2000 in the same approximate proportions as in the Russell 2000. However, the Fund may use a “representative sampling” strategy, meaning it may invest in a sample of the securities in the Russell 2000 whose risk, return, and other characteristics closely resemble the risk, return, and other characteristics of the Russell 2000 as a whole, when the Fund’s sub-adviser believes it is in the best interest of the Fund (e.g., when replicating the Russell 2000 involves practical difficulties or substantial costs, a Russell 2000 constituent becomes temporarily illiquid, unavailable, or less liquid, or as a result of legal restrictions or limitations that apply to the Fund but not to the Russell 2000).

The Fund’s sub-adviser generally utilizes a proprietary, systematic model to manage the Fund’s options positions in an objective, rules-based manner, although the sub-adviser may actively manage the written call options prior to expiration to potentially capture gains and minimize losses due to the movement of the Russell 2000.
The Fund’s options collar strategy typically consists of two components: (i) selling call options on the Russell 2000 or another reference asset representing U.S. equity securities on up to 100% of the value of the equity securities held by the Fund to generate premium from such options, while (ii) simultaneously reinvesting a portion of such premium to buy put options on the same reference asset(s) to “hedge” or mitigate the downside risk associated with owning equity securities.
Call Options. A written (sold) call option gives the seller the obligation to sell shares of the reference asset at a specified price (“strike price”) until a specified date (“expiration date”). The writer (seller) of the call option receives an amount (premium) for writing (selling) the option. In the event the reference asset appreciates above the strike price and the holder exercises the call option, the Fund will have to pay the difference between the value of the reference asset and the strike price or deliver the reference asset (which loss is offset by the premium initially received), and in the event the reference asset declines in value, the call option may end up worthless and the Fund retains the premium. The call options written by the Fund will be collateralized by the Fund’s equity holdings at the time the Fund sells the options.
Put Options. When the Fund purchases a put option, the Fund pays an amount (premium) to acquire the right to sell shares of a reference asset at a strike price until the expiration date. In the event the reference asset declines in value below the strike price and the Fund exercises its put option, the Fund will be entitled to receive the difference between the value of the reference asset and the strike price (which gain is offset by the premium originally paid by the Fund), and in the event the reference asset closes above the strike price as of the expiration date, the put option may end up worthless and the Fund’s loss is limited to the amount of premium it paid.
The options purchased or sold by the Fund will typically have an expiration date approximately one-month from the time of purchase or sale. The Fund expects the total value of the call options and the total value of the put options to each be up to 100% of the Fund’s net assets. The Fund will use a portion of the premium received from writing call options to purchase put options. Call options written by the Fund will typically have a strike price that is at, near, or higher than the current price of the reference asset, and put options purchased by the Fund will typically have a strike price that is lower (in some cases, significantly lower) than the current price of the reference asset. In addition, both the call and put options will be traded on a national securities exchange and be settled in cash.
The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. Additionally, the Fund’s investment strategies may involve active and frequent trading resulting in high portfolio turnover.
Under normal circumstances, at least 80% of the Fund’s net assets, plus borrowings for investment purposes, will be invested in securities, or derivative instruments linked to securities, of companies that are included in the Fund’s Reference Index.
Principal Investment Risks
The principal risks of investing in the Fund are summarized below. The principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund. Some or all of these risks may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and/or ability to meet its objectives. For more information about the risks of investing in the Fund, see the section in the Fund’s Prospectus titled “Additional Information About the Fund.”
Collared Options Strategy Risk. Writing and buying options are speculative activities and entail greater than ordinary investment risks. The Fund’s use of call and put options can lead to losses because of adverse movements in the price or value of the reference asset, which may be magnified by certain features of the options. When selling a call option, the Fund will receive a premium; however, this premium may not be enough to offset a loss incurred by the Fund if the price of the reference asset is above the strike price by an amount equal to or greater than the premium. The value of an option may be adversely affected if the market for the option becomes less liquid or smaller, and will be affected by changes in the value or yield of the option’s reference asset, an increase in interest rates, a change in the actual or perceived volatility of the stock market or the reference asset and the remaining time to expiration. Additionally, the value of an option does not increase or decrease at the same rate as the reference asset.
The Fund’s use of options may reduce the Fund’s ability to profit from increases in the value of the Fund’s equity holdings. If the price of the reference asset of a written call option rises above its strike price, the value of the option and, consequently, the Fund may decline significantly more than if the Fund invested solely in the reference asset instead of using options. Similarly, if the price of the reference asset of a purchased put option remains above its strike price, the option may

38



become worthless, and, consequently the value of the Fund may decline significantly more than if the Fund invested solely in the reference asset instead of using options.
Correlation Risk. The Fund expects to invest a portion of its assets to replicate the holdings of the Russell 2000, and the Fund’s sub-adviser does not expect to sell shares of an equity security due to current or projected underperformance of a security, industry, or sector, unless that security is removed from the Russell 2000. Although the Fund expects to invest a portion of its assets to replicate the holdings of the Russell 2000, the performance of such portion of the Fund and the Russell 2000 may differ from each other for a variety of reasons. For example, the Fund incurs operating expenses and portfolio transaction costs not incurred by the Russell 2000. In addition, the Fund may not be fully invested in the securities of the Russell 2000 at all times or may hold securities not included in the Russell 2000.
Derivative Securities Risks. The Fund invests in options that derive their performance from the performance of an underlying equity security. Derivatives, such as the options in which the Fund invests, can be volatile and involve various types and degrees of risks, depending upon the characteristics of a particular derivative. Derivatives may entail investment exposures that are greater than their cost would suggest, meaning that a small investment in a derivative could have a substantial impact on the performance of the Fund. The Fund could experience a loss if its derivatives do not perform as anticipated, the derivatives are not correlated with the performance of their underlying security, or if the Fund is unable to purchase or liquidate a position because of an illiquid secondary market. The market for many derivatives is, or suddenly can become, illiquid. Changes in liquidity may result in significant, rapid, and unpredictable changes in the prices for derivatives.
Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers. 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 the Fund and its investments. For example, the global pandemic caused by COVID-19, a novel coronavirus, and the aggressive responses taken by many governments, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines or similar restrictions, has had negative impacts, and in many cases severe impacts, on markets worldwide. The COVID-19 pandemic has caused prolonged disruptions to the normal business operations of companies around the world and the impact of such disruptions is hard to predict. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets.
ETF Risks. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:
Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
Cash Redemption Risk. The Fund’s investment strategy may require it to redeem shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.
Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.
Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.

39



Trading. Although Shares are listed for trading on NYSE Arca, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares, and this could lead to differences between the market price of the Shares and the underlying value of those Shares.
High Portfolio Turnover Risk. The Fund may frequently buy and sell portfolio securities and other assets to rebalance the Fund’s exposure to specific securities. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause the Fund’s performance to be less than you expect.
Industry Exposure Risk. From time to time, the Fund may invest a significant percentage of its assets in issuers in a single industry (or the same group of industries). To the extent the Fund’s investments are concentrated in or have significant exposure to a particular issuer, industry, or group of industries, the Fund may be more vulnerable to adverse events affecting such issuer, industry, or group of industries than if the Fund’s investments were more broadly diversified. The Fund’s industry exposure is expected to vary over time based on the composition of the Reference Index.
Management Risk. The Fund is actively-managed and may or may not meet its investment objective based on the portfolio managers’ success or failure to implement investment strategies for the Fund.
Market Capitalization Risk.
Small-Capitalization Investing. The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of larger-capitalization companies. The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than larger capitalization stocks or the stock market as a whole. Some small capitalization companies have limited product lines, markets, and financial and managerial resources and tend to concentrate on fewer geographical markets relative to larger capitalization companies. There is typically less publicly available information concerning smaller-capitalization companies than for larger, more established companies. Small-capitalization companies also may be particularly sensitive to changes in interest rates, government regulation, borrowing costs and earnings.
Model and Data Risk. The sub-adviser will make use of quantitative models and information and data supplied by third parties to, among other things, help determine the strike prices of the Fund’s options positions. To the extent the models used by the sub-adviser or the information and data supplied by third parties are incorrect or incomplete, the decisions made by the sub-adviser in reliance thereon will expose the Fund to potential risks and could lead to the Fund incurring losses on its investments.
New Fund Risk. The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.
Non-Diversification Risk. The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance. However, the Fund intends to satisfy the diversification requirements for qualifying as a RIC under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”).
Sector Risk. To the extent the Fund invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors.
Health Care Sector Risk. Companies in the health care sector are subject to extensive government regulation and their profitability can be significantly affected by restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure (including price discounting), limited product lines, an increased emphasis on the delivery of healthcare through outpatient services, loss or impairment of intellectual property rights and litigation regarding product or service liability.
Tax Risk. The Fund expects to generate premiums from its sale of call options. These options are expected to result in capital gains or losses for federal income tax purposes and may be subject to mark-to-market rules. These gains or losses will be wholly or partly long-term or short-term depending on the nature of the options sold by the Fund and will take into account premiums generated. In addition, stocks that are hedged with put options may not be eligible for long-term capital gains tax treatment. If positions held by the Fund were treated as “straddles” for federal income tax purposes, or the Fund’s risk of loss with respect to a position was otherwise diminished as set forth in Treasury Regulations, dividends on stocks that are a part of such positions would not constitute qualified dividend income subject to such favorable income tax treatment and would not be eligible for the dividends received deduction for corporate shareholders. In addition, generally, straddles are subject to certain rules that may

40



affect the amount, character and timing of the Fund’s gains and losses with respect to straddle positions. The Fund is not designed for investors seeking a tax efficient investment.
Tracking Stock Risk. Tracking stock is a separate class of common stock designed to “track” the performance of a specific unit or operating division within a larger company. As a result, a tracking stock’s value may decline even if the common stock of the larger company increases in value. Tracking stocks share many of the same investing risks as common stocks, but the holders of tracking stock may not share the same rights as holders of a company’s common stock.
Performance
The Fund is new and therefore does not have a performance history for a full calendar year. In the future, performance information for the Fund will be presented in this section. Updated performance information is also available on the Fund’s website at www.etf.nationwide.com.

Purchase and Sale of Shares
Shares are listed on the Exchange, and individual Shares may only be bought and sold in the secondary market through brokers at market prices, rather than NAV. Because Shares trade at market prices rather than NAV, Shares may trade at a price greater than NAV (premium) or less than NAV (discount).
The Fund issues and redeems Shares at NAV only in large blocks known as “Creation Units,” which only APs (typically, broker-dealers) may purchase or redeem. The Fund generally issues and redeems Creation Units in exchange for a portfolio of securities and/or a designated amount of U.S. cash.
Investors may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase Shares (bid) and the lowest price a seller is willing to accept for Shares (ask) when buying or selling Shares in the secondary market (the “bid-ask spread”). Recent information about the Fund, including its NAV, market price, premiums and discounts, and bid-ask spreads is available on the Fund’s website at www.etf.nationwide.com
Tax Information
Fund distributions are generally taxable as ordinary income, qualified dividend income, or capital gains (or a combination), unless your investment is in an individual retirement account (“IRA”) or other tax-advantaged account. Distributions on investments made through tax-deferred arrangements may be taxed later upon withdrawal of assets from those accounts.
Financial Intermediary Compensation
If you purchase Shares through a broker-dealer or other financial intermediary (such as a bank) (an “Intermediary”), the Adviser or its affiliates may pay Intermediaries for certain activities related to the Fund, including participation in activities that are designed to make Intermediaries more knowledgeable about exchange traded products, including the Fund, or for other activities, such as marketing, educational training or other initiatives related to the sale or promotion of Shares. These payments may create a conflict of interest by influencing the Intermediary and your salesperson to recommend the Fund over another investment. Any such arrangements do not result in increased Fund expenses. Ask your salesperson or visit the Intermediary’s website for more information.
ADDITIONAL INFORMATION ABOUT THE INDEXES
Each Index is calculated by an independent third-party calculation agent that is not affiliated with the applicable Fund, its adviser, its sub-adviser, its distributor, or any of their affiliates. An Index Provider may delay or change a scheduled rebalancing or reconstitution of an Index at its sole discretion.

Risk contribution is a quantitative measure that communicates how total portfolio risk decomposes into various portfolio constituents, (i.e., securities, and is based on marginal risk contribution).
Marginal risk contribution calculations seek to identify the increase in variability of a portfolio’s returns from the addition of a security to such portfolio. For purposes of the Indexes underlying the Risk-Based Funds, such calculations are based on the volatility and correlation of the relevant securities for the most recent one-year calculation period.
Rothschild & Co Risk-Based US Index (the “Risk-Based US Index”)
The Risk-Based US Index universe consists of common stocks with a primary listing on the New York Stock Exchange (“NYSE”) (including NYSE Arca and NYSE MKT), the NASDAQ Global Select Market, the NASDAQ Select Market, and the NASDAQ Capital Market. The free-float market capitalization (i.e., market capitalization based on the number of shares available to the public) of each security is used to determine the eligible company size to be included in the Index’s Eligible Universe.
Rothschild & Co Risk-Based International Index (the “Risk-Based International Index”)

ADDITIONAL INFORMATION ABOUT THE FUNDS
Investment Objectives
Each Fund’s investment objective has been adopted as a non-fundamental investment policy and may be changed without shareholder approval upon written notice to shareholders.
Temporary Defensive Positions (Nationwide Nasdaq-100 Risk-Managed Income ETF, Nationwide S&P 500 Risk-Managed Income ETF, Nationwide Dow Jones Risk-Managed Income ETF and Nationwide Russell 2000 Risk-Managed Income ETF (the “Risk-Managed Income Funds”))
To respond to adverse market, economic, political, or other conditions, a Fund may invest up to 100% of its assets in a temporary defensive manner by holding all or a substantial portion of its assets in cash, cash equivalents, or other high quality short-term investments. Examples of temporary defensive investments include short-term U.S. government securities, commercial paper, bank obligations, repurchase agreements, money market fund shares, and other money market instruments. A Fund also may invest in these types of defensive investments or hold cash while looking for suitable investment opportunities or to maintain liquidity. In these circumstances, the Fund may be unable to achieve its investment objective.
Manager of Managers Structure
The Funds and the Adviser have received exemptive relief from the SEC permitting the Adviser (subject to certain conditions and the approval of the Funds’ Board of Trustees (the “Board”)) to change or select sub-advisers without obtaining shareholder approval. The relief also permits the Adviser to materially amend the terms of agreements with a sub-adviser (including an increase in the fee paid by the Adviser to the sub-adviser (and not paid by the applicable Fund)) or to continue the employment of a sub-adviser after an event that would otherwise cause the automatic termination of services with Board approval, but without shareholder approval. Shareholders will be notified of any sub-adviser changes.
Principal Investment Strategies
Each Fund has adopted a policy, as described below, to comply with Rule 35d-1 under the Investment Company Act of 1940 (the “1940 Act”). Such policy has been adopted as a non-fundamental investment policy and may be changed without shareholder approval upon 60 days’ written notice to shareholders. With respect to the policies below, the Funds define “equity securities” to mean common and preferred stocks, rights, warrants, depositary receipts, equity interests in real estate investment trusts (“REITs”), and master limited partnerships.
Under normal circumstances, at least 80% of the net assets, plus borrowings for investment purposes, of each of the Risk-Based U.S. Fund and MaxDiv U.S. Fund will be invested in equity securities that are principally traded in the United States.
Under normal circumstances, at least 80% of the net assets, plus borrowings for investment purposes, of the Risk-Based International Fund will be invested in equity securities that are principally traded in Europe, Australasia, or the Far East.
Under normal circumstances, at least 80% of the net assets, plus borrowings for investment purposes, of each Risk-Managed Income Fund will be invested in securities, or derivative instruments linked to securities, of companies that are included in such Fund’s Reference Index.
Principal Investment Risks
This section provides additional information regarding the principal risks described in each Fund Summary. As in each Fund Summary, the principal risks below are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk described below is considered a “principal risk” of investing in the applicable Fund, regardless of the order in which it appears. Each of the factors below could have a negative impact on the applicable Fund’s performance and trading prices. Each risk applies to each Fund unless otherwise specified.
Collared Options Strategy Risk (Risk-Managed Income Funds only). Writing and buying options are speculative activities and entail greater than ordinary investment risks. Each Fund’s use of call and put options can lead to losses because of adverse movements in the price or value of the reference asset, which may be magnified by certain features of the options. When selling a call option, a Fund will receive a premium; however, this premium may not be enough to offset a loss incurred by the Fund if the price of the reference asset is above the strike price by an amount equal to or greater than the premium. The value of an option may be adversely affected if the market for the option becomes less liquid or smaller, and will be affected by changes in the value or yield of the option’s reference asset, an increase in interest rates, a change in the actual or perceived volatility of the stock market or the reference asset and the remaining time to expiration. Additionally, the value of an option does not increase or decrease at the same rate as the reference asset.

43



Each Fund’s use of options may reduce the Fund’s ability to profit from increases in the value of the Fund’s equity holdings. If the price of the reference asset of a written call option rises above its strike price, the value of the option and, consequently, a Fund, may decline significantly more than if the Fund invested solely in the reference asset instead of using options. Similarly, if the price of the reference asset of a purchased put option remains above its strike price, the option may become worthless, and, consequently the value of a Fund may decline significantly more than if the Fund invested solely in the reference asset instead of using options.
Correlation Risk (Risk-Managed Income Funds only). Each Fund expects to invest a portion of its assets to replicate the holdings of the applicable Reference Index, and the Fund’s sub-adviser does not expect to sell shares of an equity security due to current or projected underperformance of a security, industry, or sector, unless that security is removed from the applicable Reference Index. Although each Fund expects to invest a portion of its assets to replicate the holdings of the applicable Reference Index, the performance of such portion of the Fund and the applicable Reference Index may differ from each other for a variety of reasons. For example, a Fund incurs operating expenses and portfolio transaction costs not incurred by the applicable Reference Index. In addition, a Fund may not be fully invested in the securities of the applicable Reference Index at all times or may hold securities not included in the applicable Reference Index. The use of sampling techniques may affect the Fund’s ability to achieve close correlation between the portion of the Fund invested in the applicable Reference Index constituents and the applicable Reference Index itself.
Currency Exchange Rate Risk (Risk-Based International Fund and Nasdaq-100 Risk-Managed Income Fund only). Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of each Fund’s investments and the value of your Shares. Because each Fund’s NAV is determined based on U.S. dollars, the U.S. dollar value of your investment in a Fund may go down if the value of the local currency of the non-U.S. markets in which the Fund invests depreciates against the U.S. dollar. This is true even if the local currency value of securities in a Fund’s holdings goes up. Conversely, the dollar value of your investment in a Fund may go up if the value of the local currency appreciates against the U.S. dollar. The value of the U.S. dollar measured against other currencies is influenced by a variety of factors. These factors include: national debt levels and trade deficits, changes in balances of payments and trade, domestic and foreign interest and inflation rates, global or regional political, economic or financial events, monetary policies of governments, actual or potential government intervention, and global energy prices. Political instability, the possibility of government intervention and restrictive or opaque business and investment policies may also reduce the value of a country’s currency. Government monetary policies and the buying or selling of currency by a country’s government may also influence exchange rates. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in a Fund may change quickly and without warning, and you may lose money.
Depositary Receipt Risk (Risk-Based International Fund and Nasdaq-100 Risk-Managed Income Fund only). Each Fund may hold the securities of non-U.S. companies in the form of American Depositary Receipts (“ADRs”) and Global Depositary Receipts (“GDRs”). ADRs are negotiable certificates issued by a U.S. financial institution that represent a specified number of shares in a foreign stock and trade on a U.S. national securities exchange, such as the New York Stock Exchange. Sponsored ADRs are issued with the support of the issuer of the foreign stock underlying the ADRs and carry all of the rights of common shares, including voting rights. GDRs are similar to ADRs but may be issued in bearer form and are typically offered for sale globally and held by a foreign branch of an international bank. The underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities. Issuers of unsponsored depositary receipts are not contractually obligated to disclose material information in the U.S. and, therefore, such information may not correlate to the market value of the unsponsored depositary receipt. The underlying securities of the ADRs and GDRs in a Fund’s portfolio are usually denominated or quoted in currencies other than the U.S. Dollar. As a result, changes in foreign currency exchange rates may affect the value of a Fund’s portfolio. In addition, because the underlying securities of ADRs and GDRs trade on foreign exchanges at times when the U.S. markets are not open for trading, the value of the securities underlying the ADRs and GDRs may change materially at times when the U.S. markets are not open for trading, regardless of whether there is an active U.S. market for Shares.
Derivatives Risk (Risk-Managed Income Funds only). Each Fund may invest in derivatives, which are financial instruments that derive their performance from the performance of an underlying security or index. Derivatives can be volatile and involve various types and degrees of risks, depending upon the characteristics of a particular derivative. Derivatives may entail investment exposures that are greater than their cost would suggest, meaning that a small investment in a derivative could have a substantial impact on the performance of a Fund. Each Fund could experience a loss if derivatives do not perform as anticipated, the derivatives are not correlated with the performance of other investments which are used to hedge, or if the Fund is unable to liquidate a position because of an illiquid secondary market. The market for many derivatives is, or suddenly can become, illiquid. Changes in liquidity may result in significant, rapid and unpredictable changes in the prices for derivatives.

44



Emerging Markets Risk (Nasdaq-100 Risk-Managed Income Fund only). The Fund may have exposure to emerging markets. Investing in companies doing business in emerging markets will, among other things, expose the Fund to all the risks described below in the “Foreign Securities Risk” section. However, there are greater risks involved in investing in emerging market countries and/or their securities markets than there are in more developed countries and/or markets. Generally, economic structures in these countries are less diverse and mature than those in developed countries, and their political systems are less stable. Investments in emerging market countries may be affected by national policies that restrict foreign investment in certain issuers or industries. Sanctions and other intergovernmental actions may be undertaken against an emerging market country, which may result in the devaluation of the country’s currency, a downgrade in the country’s credit rating, and a decline in the value and liquidity of the country’s securities. Sanctions could result in the immediate freeze of securities issued by an emerging market company or government, impairing the ability of a Fund to buy, sell, receive or deliver these securities.
Equity Market Risk. Equity securities are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. These investor perceptions are based on various and unpredictable factors including: expectations regarding government, economic, monetary and fiscal policies; inflation and interest rates; economic expansion or contraction; and global or regional political, economic and banking crises. If you held common stock, or common stock equivalents, of any given issuer, you would generally be exposed to greater risk than if you held preferred stocks and debt obligations of the issuer because common stockholders, or holders of equivalent interests, generally have inferior rights to receive payments from issuers in comparison with the rights of preferred stockholders, bondholders, and other creditors of such issuers.
Beginning in the first quarter of 2020, financial markets in the United States and around the world experienced extreme and in many cases unprecedented volatility and severe losses due to the global pandemic caused by COVID‑19, a novel coronavirus. The pandemic has resulted in a wide range of social and economic disruptions, including closed borders, voluntary or compelled quarantines of large populations, stressed healthcare systems, reduced or prohibited domestic or international travel, supply chain disruptions, and so-called “stay-at-home” orders throughout much of the United States and many other countries. The fall-out from these disruptions has included the rapid closure of businesses deemed “non-essential” by federal, state, or local governments and rapidly increasing unemployment, as well as greatly reduced liquidity for certain instruments at times. Some sectors of the economy and individual issuers have experienced particularly large losses. Such disruptions may continue for an extended period of time or reoccur in the future to a similar or greater extent. In response, the U.S. government and the Federal Reserve have taken extraordinary actions to support the domestic economy and financial markets, resulting in very low interest rates and in some cases negative yields. It is unknown how long circumstances related to the pandemic will persist, whether they will reoccur in the future, whether efforts to support the economy and financial markets will be successful, and what additional implications may follow from the pandemic. The impact of these events and other epidemics or pandemics in the future could result in disruptions in the trading markets, increased premiums or discounts to the Fund’s NAV, and adverse effects on Fund performance.
ETF Risks. Each Fund is an ETF, and, because of an ETF’s structure, is exposed to the following risks:
APs, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
Cash Redemption Risk (Risk-Managed Income Funds only). Each Fund’s investment strategy may require it to effect redemptions, in whole or in part, for cash. As a result, a Fund may be required to sell portfolio securities to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize investment income and/or capital gains or losses that it might not have recognized if it had completely satisfied the redemption in-kind. As a result, a Fund may be less tax efficient if it includes such a cash payment than if the in-kind redemption process was used exclusively. In addition, cash redemptions may incur higher brokerage costs than in-kind redemptions and these added costs may be borne by a Fund and negatively impact Fund performance.
Costs of Buying or Selling Shares. Investors buying or selling Shares in the secondary market will pay brokerage commissions or other charges imposed by brokers, as determined by that broker. Brokerage commissions are often a fixed amount and may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Shares. In addition, secondary market investors will also incur the cost of the difference between the price at which an investor is willing to buy Shares (the “bid” price) and the price at which an investor is willing to sell Shares (the “ask” price). This difference in bid and ask prices is often referred to as the “spread” or “bid-ask spread.” The bid-ask spread varies over time for Shares based on trading volume and market liquidity and is generally lower if Shares have more trading volume and market liquidity and higher if Shares have little trading volume and market liquidity. Further, a relatively small investor base

45



in the Fund, asset swings in the Fund and/or increased market volatility may cause increased bid-ask spreads. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.
Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. Because securities held by the Risk-Based International Fund and Nasdaq-100 Risk-Managed Income Fund (the “Foreign Funds”) may trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, the Foreign Funds are likely to experience premiums and discounts greater than those of domestic ETFs.
Trading. Although Shares are listed for trading on the Exchange and may be listed or traded on U.S. and non-U.S. stock exchanges other than the Exchange, there can be no assurance that an active trading market for such Shares will develop or be maintained. Trading in Shares 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 Exchange “circuit breaker” rules, which temporarily halt trading on the Exchange when a decline in the S&P 500® Index during a single day reaches certain thresholds (e.g., 7%, 13%, and 20%). Additional rules applicable to the Exchange may halt trading in Shares when extraordinary volatility causes sudden, significant swings in the market price of Shares. There can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares, and this could lead to differences between the market price of the Shares and the underlying value of those Shares.
Foreign Securities Risk (Risk-Based International Fund and Nasdaq-100 Risk-Managed Income Fund only). Investments in non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. For example, investments in non-U.S. securities may be subject to risk of loss due to foreign currency fluctuations or to political or economic instability. There may be less information publicly available about a non-U.S. issuer than a U.S. issuer. Non-U.S. issuers may be subject to different accounting, auditing, financial reporting and investor protection standards than U.S. issuers. Investments in non-U.S. securities may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. With respect to certain countries, there is the possibility of government intervention and expropriation or nationalization of assets. Because legal systems differ, there is also the possibility that it will be difficult to obtain or enforce legal judgments in certain countries. Each of these factors can make investments in the Fund more volatile and potentially less liquid than other types of investments. Since foreign exchanges may be open on days when a Fund does not price its Shares, the value of the securities in a Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s Shares. Conversely, Shares may trade on days when foreign exchanges are closed. Each of these factors can make investments in a Fund more volatile and potentially less liquid than other types of investments.
Geographic Investment Risk (Risk-Based International Fund only). To the extent that the Fund’s Index invests a significant portion of its assets in the securities of companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region. For example, political and economic conditions and changes in regulatory, tax, or economic policy in a country could significantly affect the market in that country and in surrounding or related countries and have a negative impact on the Fund’s performance. Currency developments or restrictions, political and social instability, and changing economic conditions have resulted in significant market volatility.
Risks Related to Investing in Europe. The economies and markets of European countries are often closely connected and interdependent, and events in one country in Europe can have an adverse impact on other European countries. The Fund makes investments in securities of issuers that are domiciled in, or have significant operations in, member countries of the European Union (“EU”) that are subject to economic and monetary controls that can adversely affect the Fund’s investments. The European financial markets have experienced volatility and adverse trends in recent years and these events have adversely affected the exchange rate of the euro and may continue to significantly affect other European countries. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and their trading partners, including some or all of the European countries in which the Fund invests.

46



The UK formally exited from the EU on January 31, 2020 (known as “Brexit”), and effective December 31, 2020, the UK ended a transition period during which it continued to abide by the EU’s rules and the UK’s trade relationships with the EU were generally unchanged. Following this transition period, the impact on the UK and European economies and the broader global economy could be significant, resulting in negative impacts, such as increased volatility and illiquidity, and potentially lower economic growth of markets in the UK, Europe and globally, which may adversely affect the value of the Fund’s investments.
Risks Related to Investing in Japan. The Japanese economy may be subject to considerable degrees of economic, political and social instability, which could have a negative impact on Japanese securities. Since the year 2000, Japan’s economic growth rate has remained relatively low and it may remain low in the future. In addition, Japan is subject to the risk of natural disasters, such as earthquakes, volcanoes, typhoons and tsunamis. Additionally, decreasing U.S. imports, new trade regulations, changes in the U.S. dollar exchange rates, a recession in the United States or continued increases in foreclosure rates may have an adverse impact on the economy of Japan. Japan also has few natural resources, and any fluctuation or shortage in the commodity markets could have a negative impact on Japanese securities.
High Portfolio Turnover (Risk-Managed Income Funds only). Each Fund may frequently buy and sell portfolio securities and other assets to rebalance the Fund’s exposure to various market sectors. Higher portfolio turnover may result in a Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause a Fund’s performance to be less than you expect.
Industry Exposure Risk (Risk-Managed Income Funds only). From time to time, a Fund may invest a significant percentage of its assets in issuers in a single industry (or the same group of industries). To the extent a Fund’s investments are concentrated in or have significant exposure to a particular issuer, industry, or group of industries, the Fund may be more vulnerable to adverse events affecting such issuer, industry, or group of industries than if the Fund’s investments were more broadly diversified. A Fund’s industry exposure is expected to vary over time based on the composition of the Reference Index.
Management Risk (Risk-Managed Income Funds only). Each Fund is actively-managed and may or may not meet its investment objective based on the portfolio managers’ success or failure to implement investment strategies for the Fund.
Market Capitalization Risk.
Large-Capitalization Investing (All Funds, except Russell 2000 Risk-Managed Income Fund). The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.
Small-Capitalization Investing (Russell 2000 Risk-Managed Income Fund only). The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of larger-capitalization companies. The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than larger capitalization stocks or the stock market as a whole. Some small capitalization companies have limited product lines, markets, and financial and managerial resources and tend to concentrate on fewer geographical markets relative to larger capitalization companies. There is typically less publicly available information concerning smaller-capitalization companies than for larger, more established companies. Small-capitalization companies also may be particularly sensitive to changes in interest rates, government regulation, borrowing costs and earnings.
Model and Data Risk - Active Funds (Risk-Managed Income Funds only). The sub-adviser will make use of quantitative models and information and data supplied by third parties to, among other things, help determine the strike prices of each Fund’s options positions. To the extent the models used by the sub-adviser or the information and data supplied by third parties are incorrect or incomplete, the decisions made by the sub-adviser in reliance thereon will expose a Fund to potential risks and could lead to the Fund incurring losses on its investments.
Models and Data Risk - Index Funds (Risk-Based Funds and MaxDiv U.S. Fund (collectively, the “Index Funds”) only). When Models and Data prove to be incorrect or incomplete, any decisions made in reliance thereon expose the Indexes and the Funds to potential risks. Some of the models used to construct each Index are predictive in nature. The use of predictive models has inherent risks. For example, such models may incorrectly forecast future behavior, leading to potential losses. In addition, in unforeseen or certain low-probability scenarios (often involving a market disruption of some kind), such models may produce unexpected results, which can result in losses for a Fund. Furthermore, because predictive models are usually constructed based on historical data supplied by third parties, the success of relying on such models may depend heavily on the accuracy and reliability of the supplied historical data.

47



New Fund Risk (S&P 500 Risk-Managed Income Fund, Dow Jones Risk-Managed Income Fund and Russell 2000 Risk-Managed Income Fund only). Each Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.
Non-Diversification Risk (Risk-Managed Income Funds only). Although each Fund intends to invest in a variety of securities and instruments, each Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, a Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase a Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance. However, each Fund intends to satisfy the diversification requirements for qualifying as a RIC under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”).
Passive Investment Risk (Index Funds only). Each Fund invests in the securities included in, or representative of, its Index regardless of their investment merit. Each Fund does not attempt to outperform its Index or take defensive positions in declining markets. As a result, a Fund’s performance may be adversely affected by a general decline in the market segments relating to its Index. The returns from the types of securities in which a Fund invests may underperform returns from the various general securities markets or different asset classes. This may cause a Fund to underperform other investment vehicles that invest in different asset classes. Different types of securities (for example, large-, mid- and small-capitalization stocks) tend to go through cycles of doing better – or worse – than the general securities markets. In the past, these periods have lasted for as long as several years.
Portfolio Turnover Risk (Risk-Based Funds only). Each Fund may trade all or a significant portion of the securities in its portfolio in connection with each rebalance and reconstitution of the Index. A high portfolio turnover rate increases transaction costs, which may increase a Fund’s expenses. Frequent trading may also cause adverse tax consequences for investors in a Fund due to an increase in short-term capital gains.
Preferred Securities Risk (MaxDiv U.S. Fund only). Preferred securities are subject to risks associated with both equity and debt instruments. Because many preferred securities allow the issuer to convert its preferred stock into common stock, preferred securities are often sensitive to declining common stock values. In addition, certain preferred securities contain provisions that allow an issuer to skip or defer distributions, which may be more likely when the issuer is less able to make dividend payments because of financial difficulties. Preferred securities can also be affected by changes in interest rates, especially if dividends are paid at a fixed rate, and may also include call features in favor of the issuer. In the event of redemptions by the issuer, a Fund may not be able to reinvest the proceeds at comparable or favorable rates of return. Preferred securities are generally subordinated to bonds and other debt securities in an issuer’s capital structure in terms of priority for corporate income and liquidation payments and may trade less frequently and in a more limited volume and may be subject to more abrupt or erratic price movements than many other securities.
Sector Risk. Each Fund’s investing approach may result in an emphasis on certain sectors or sub-sectors of the market at any given time. To the extent a Fund invests more heavily in one sector or sub-sector of the market, it thereby presents a more concentrated risk and its performance will be especially sensitive to developments that significantly affect those sectors or sub-sectors. In addition, the value of a Fund’s shares may change at different rates compared to the value of shares of a fund with investments in a more diversified mix of sectors and industries. An individual sector or sub-sector of the market may have above-average performance during particular periods but may also move up and down more than the broader market. The several industries that constitute a sector may all react in the same way to economic, political or regulatory events. A Fund’s performance could also be affected if the sectors or sub-sectors do not perform as expected. Alternatively, the lack of exposure to one or more sectors or sub-sectors may adversely affect performance.
Communications Services Sector Risk (Nasdaq-100 Risk-Managed Income Fund only). Communications services companies are subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals, or the enactment of new adverse regulatory requirements may adversely affect the business of such companies. Companies in the communications services sector can also be significantly affected by intense competition, including competition with alternative technologies such as wireless communications (including with 5G and other technologies), product compatibility, consumer preferences, rapid product obsolescence, and research and development of new products. Technological innovations may make the products and services of such companies obsolete.
Financial Sector Risk (Dow Jones Risk-Managed Income Fund only). Companies in the financial sector of an economy are often subject to extensive governmental regulation and intervention, which may adversely affect the scope of their activities, the prices they can charge and the amount of capital they must maintain. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financial sector, including effects not intended by such

48



regulation. The impact of recent or future regulation in various countries on any individual financial company or on the sector as a whole cannot be predicted.
Certain risks may impact the value of investments in the financial sector more severely than those of investments outside this sector, including the risks associated with companies that operate with substantial financial leverage. Companies in the financial sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades and adverse conditions in other related markets.
Insurance companies, in particular, may be subject to severe price competition and/or rate regulation, which may have an adverse impact on their profitability. Insurance companies are subject to extensive government regulation in some countries and can be significantly affected by changes in interest rates, general economic conditions, price and marketing competition, the imposition of premium rate caps, or other changes in government regulation or tax law. Different segments of the insurance industry can be significantly affected by mortality and morbidity rates, environmental clean-up costs and catastrophic events such as earthquakes, hurricanes and terrorist acts.
The financial sector is also a target for cyber attacks and may experience technology malfunctions and disruptions. In recent years, cyber attacks and technology failures have become increasingly frequent and have caused significant losses.
Health Care Sector Risk (Dow Jones Risk-Managed Income Fund and Russell 2000 Risk-Managed Income Fund only). Companies in the health care sector are subject to extensive government regulation and their profitability can be significantly affected by restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure (including price discounting), limited product lines and an increased emphasis on the delivery of healthcare through outpatient services. Companies in the health care sector are heavily dependent on obtaining and defending patents, which may be time consuming and costly, and the expiration of patents may also adversely affect the profitability of these companies. Health care companies are also subject to extensive litigation based on product liability and similar claims. In addition, their products can become obsolete due to industry innovation, changes in technologies or other market developments. Many new products in the health care sector require significant research and development and may be subject to regulatory approvals, all of which may be time consuming and costly with no guarantee that any product will come to market.
Information Technology Sector Risk (Nasdaq-100 Risk-Managed Income Fund, S&P 500 Risk-Managed Income Fund and Dow Jones Risk-Managed Income Fund only). Market or economic factors impacting information technology companies and companies that rely heavily on technological advances could have a significant effect on the value of the Fund’s investments. The value of stocks of information technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Information technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability.
Socially Responsible Investment Risk (MaxDiv U.S. Fund only). Because the methodology of the Index eliminates securities of certain issuers for non-financial reasons, an Index, and consequently a Fund, may underperform the broader equity market or other indices or funds that do not utilize similar criteria when selecting investments.
Tax Risk (Risk-Managed Income Funds only). Each Fund expects to generate premiums from its sale of call options. These options are expected to result in capital gains or losses for federal income tax purposes and may be subject to mark-to-market rules. These gains or losses will be wholly or partly long-term or short-term depending on the nature of the options sold by a Fund and will take into account premiums generated. In addition, stocks that are hedged with put options may not be eligible for long-term capital gains. If positions held by a Fund were treated as “straddles” for federal income tax purposes, or the Fund’s risk of loss with respect to a position was otherwise diminished as set forth in Treasury Regulations, dividends on stocks that are a part of such positions would not constitute qualified dividend income subject to such favorable income tax treatment and would not be eligible for the dividends received deduction for corporate shareholders. In addition, generally, straddles are subject to certain rules that may affect the amount, character and timing of a Fund’s gains and losses with respect to straddle positions by requiring, among other things, that: (1) any loss realized on disposition of one position of a straddle may not be recognized to the extent that the Fund has unrealized gains with respect to the other position in such straddle; (2) the Fund’s holding period in straddle positions be suspended while the straddle exists (possibly resulting in a gain being treated as short-term capital gain rather than long-term capital gain); (3) the losses recognized with respect to certain straddle positions that are part of a mixed straddle and that are not subject to Code Section 1256 be treated as 60% long-term and 40% short-term capital loss; (4) losses recognized with respect to certain straddle positions that would otherwise constitute short-term capital losses be treated as long-term capital losses; and (5) the deduction of interest and carrying charges attributable to certain straddle positions may be deferred. Each Fund is not designed for investors seeking a tax efficient investment.


49



Tracking Error Risk (Index Funds only). As with all index funds, the performance of each Fund and its respective Index may differ from each other for a variety of reasons. For example, the Funds incur operating expenses and portfolio transaction costs not incurred by an Index. In addition, the Funds may not be fully invested in the securities of their respective Index at all times or may hold securities not included in the Index. A Fund may use a representative sampling strategy to achieve its investment objective, if the Fund’s sub-adviser believes it is in the best interest of the Fund, which generally can be expected to produce a greater non-correlation risk.
Tracking Stock Risk (Risk-Managed Income Funds only). Tracking stock is a separate class of common stock designed to “track” the performance of a specific unit or operating division within a larger company. As a result, a tracking stock’s value may decline even if the common stock of the larger company increases in value. Tracking stocks share many of the same investing risks as common stocks, but the holders of tracking stock may not share the same rights as holders of a company’s common stock.

HOW TO BUY AND SELL SHARES
Each Fund issues and redeems Shares at NAV only in Creation Units. Only APs may acquire Shares directly from a Fund, and only APs may tender their Shares for redemption directly to a Fund, at NAV. APs must be a member or participant of a clearing agency registered with the SEC and must execute a Participant Agreement that has been agreed to by the Distributor (defined below), and that has been accepted by a Fund’s transfer agent, with respect to purchases and redemptions of Creation Units. Once created, Shares trade in the secondary market in quantities less than a Creation Unit.

52



Most investors buy and sell Shares in secondary market transactions through brokers. Shares are listed for trading on the secondary market on the Exchange and can be bought and sold throughout the trading day like other publicly traded securities.
When buying or selling Shares through a broker, you will incur customary brokerage commissions and charges, and you may pay some or all of the spread between the bid and the offer price in the secondary market on each leg of a round trip (purchase and sale) transaction. In addition, because secondary market transactions occur at market prices, you may pay more than NAV when you buy Shares and receive less than NAV when you sell those Shares.
Book Entry
Shares are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding Shares.
Investors owning Shares are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for all Shares. DTC’s participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of Shares, you are not entitled to receive physical delivery of stock certificates or to have Shares registered in your name, and you are not considered a registered owner of Shares. Therefore, to exercise any right as an owner of Shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book entry or “street name” through your brokerage account.
Frequent Purchases and Redemptions of Shares
The Funds impose no restrictions on the frequency of purchases and redemptions of Shares. In determining not to approve a written, established policy, the Board evaluated the risks of market timing activities by Fund shareholders. Purchases and redemptions by APs, who are the only parties that may purchase or redeem Shares directly with a Fund, are an essential part of the ETF process and help keep Share trading prices in line with NAV. As such, the Funds accommodate frequent purchases and redemptions by APs. However, the Board has also determined that frequent purchases and redemptions for cash may increase tracking error and portfolio transaction costs and may lead to the realization of capital gains. To minimize these potential consequences of frequent purchases and redemptions, the Funds employ fair value pricing and may impose transaction fees on purchases and redemptions of Creation Units to cover the custodial and other costs incurred by a Fund in effecting trades. In addition, the Funds and the Adviser reserve the right to reject any purchase order at any time.
Determination of Net Asset Value
Each Fund’s NAV is calculated as of the scheduled close of regular trading on the New York Stock Exchange (“NYSE”), generally 4:00 p.m. Eastern time, each day the NYSE is open for business. Each NAV for a Fund is calculated by dividing the applicable Fund’s net assets by its Shares outstanding.
In calculating its NAV, each Fund generally values its assets on the basis of market quotations, last sale prices, or estimates of value furnished by a pricing service or brokers who make markets in such instruments. If such information is not available for a security held by a Fund or is determined to be unreliable, the security will be valued at fair value estimates under guidelines established by the Board (as described below).
Fair Value Pricing
The Board has adopted procedures and methodologies to fair value Fund securities whose market prices are not “readily available” or are deemed to be unreliable. For example, such circumstances may arise when: (i) a security has been de-listed or has had its trading halted or suspended; (ii) a security’s primary pricing source is unable or unwilling to provide a price; (iii) a security’s primary trading market is closed during regular market hours; or (iv) a security’s value is materially affected by events occurring after the close of the security’s primary trading market. Generally, when fair valuing a security, the Funds will take into account all reasonably available information that may be relevant to a particular valuation including, but not limited to, fundamental analytical data regarding the issuer, information relating to the issuer’s business, recent trades or offers of the security, general and/or specific market conditions and the specific facts giving rise to the need to fair value the security. Fair value determinations are made in good faith and in accordance with the fair value methodologies included in the Board-adopted valuation procedures. Due to the subjective and variable nature of fair value pricing, there can be no assurance that the Adviser or Sub-Adviser will be able to obtain the fair value assigned to the security upon the sale of such security.
Delivery of Shareholder Documents – Householding
Householding is an option available to certain investors of the Funds. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Householding for the Funds is available through certain broker-

53



dealers. If you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, please contact your broker-dealer. If you are currently enrolled in householding and wish to change your householding status, please contact your broker-dealer.
Investments by Registered Investment Companies
Section 12(d)(1) of the 1940 Act restricts investments by registered investment companies in the securities of other investment companies, including Shares. Registered investment companies are permitted to invest in a Fund beyond the limits set forth in section 12(d)(1) subject to certain terms and conditions set forth in an SEC exemptive order issued to the Adviser or rule under the 1940 Act, including that such investment companies enter into an agreement with a Fund.
DIVIDENDS, DISTRIBUTIONS, AND TAXES
Dividends and Distributions
Each Risk-Managed Income Fund intends to distribute substantially all of its net investment income and net capital gains to its shareholders at least annually. Each Risk-Managed Income Fund seeks to maintain relatively stable monthly distributions, although the amount of income earned by a Fund varies from period-to-period. Each month, each Risk-Managed Income Fund determines the amount of distribution to pay based on a combination of the amount of options premium generated from the Fund’s options collar strategy implemented for the applicable month, the dividends generated by the Fund’s underlying equity portfolio, and the appreciation of the Fund’s equity holdings. As a result of such distribution strategy, each Risk-Managed Income Fund’s distributions are expected to exceed its earnings and profits in some or all tax years, and consequently, all or a portion of the distributions made for a taxable year may be characterized as a return of capital to shareholders. A return of capital distribution will generally not be taxable, but will reduce each shareholder’s cost basis in the applicable Fund and result in a higher capital gain or lower capital loss when the Shares on which the distribution was received are sold. After a shareholder’s basis in the Shares has been reduced to zero, distributions in excess of earnings and profits will be treated as gain from the sale of the shareholder’s Shares.
Each Index Fund intends to distribute, at least annually, substantially all of its net investment income and net capital gains.
Each Fund will declare and pay capital gain distributions in cash. Distributions in cash may be reinvested automatically in additional whole Shares only if the broker through whom you purchased Shares makes such option available. Your broker is responsible for distributing the income and capital gain distributions to you.
Taxes
The following discussion is a summary of some important U.S. federal income tax considerations generally applicable to investments in a Fund. Your investment in a Fund may have other tax implications. Please consult your tax advisor about the tax consequences of an investment in Shares, including the possible application of foreign, state, and local tax laws.
Each Fund has elected or intends to elect and intends to qualify each year for treatment as a RIC. If a Fund meets certain minimum distribution requirements, a RIC is not subject to tax at the fund level on income and gains from investments that are timely distributed to shareholders. However, a Fund’s failure to qualify as a RIC or to meet minimum distribution requirements would result (if certain relief provisions were not available) in fund-level taxation and, consequently, a reduction in income available for distribution to shareholders.
Unless your investment in Shares is made through a tax-exempt entity or tax-advantaged account, such as an IRA plan, you need to be aware of the possible tax consequences when a Fund makes distributions, when you sell your Shares listed on the Exchange, and when you purchase or redeem Creation Units (APs only).
Taxes on Distributions
Each Fund intends to distribute, at least annually, substantially all of its net investment income and net capital gains. For federal income tax purposes, distributions of investment income are generally taxable as ordinary income or qualified dividend income. Taxes on distributions of capital gains (if any) are determined by how long a Fund owned the investments that generated them, rather than how long a shareholder has owned his or her Shares. Sales of assets held by a Fund for more than one year generally result in long-term capital gains and losses, and sales of assets held by a Fund for one year or less generally result in short-term capital gains and losses. Distributions of a Fund’s net capital gain (the excess of net long-term capital gains over net short-term capital losses) that are reported by such Fund as capital gain dividends (“Capital Gain Dividends”) will be taxable as long-term capital gains, which for non-corporate shareholders are subject to tax at reduced rates of up to 20% (lower rates apply to individuals in lower tax brackets). Distributions of short-term capital gain will generally be taxable as ordinary income. Dividends and distributions are generally taxable to you whether you receive them in cash or reinvest them in additional Shares.
Distributions reported by a Fund as “qualified dividend income” are generally taxed to non-corporate shareholders at rates applicable to long-term capital gains, provided holding period and other requirements are met. “Qualified dividend income” generally is income

54



derived from dividends paid by U.S. corporations or certain foreign corporations that are either incorporated in a U.S. possession or eligible for tax benefits under certain U.S. income tax treaties. In addition, dividends that the Fund receives in respect of stock of certain foreign corporations may be qualified dividend income if that stock is readily tradable on an established U.S. securities market. Certain of the Funds’ investment strategies may limit their ability to make distributions eligible to be treated as qualified dividend income. Corporate shareholders may be entitled to a dividends received deduction for the portion of dividends they receive from a Fund that are attributable to dividends received by the Fund from U.S. corporations, subject to certain limitations. Certain of the Funds’ investment strategies may limit their ability to make distributions eligible for the dividends-received deduction for corporate shareholders.
If a Fund’s distributions exceed its earnings and profits, all or a portion of the distributions made for a taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution will generally not be taxable, but will reduce each shareholder’s cost basis in a Fund and result in a higher capital gain or lower capital loss when the Shares on which the distribution was received are sold. After a shareholder’s basis in the Shares has been reduced to zero, distributions in excess of earnings and profits will be treated as gain from the sale of the shareholder’s Shares.
Shortly after the close of each calendar year, you will be informed of the amount and character of any distributions received from a Fund.
In general, your distributions are subject to federal income tax for the year in which they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year. Distributions are generally taxable even if they are paid from income or gains earned by a Fund before your investment (and thus were included in the Shares’ NAV when you purchased your Shares).
You may wish to avoid investing in a Fund shortly before a dividend or other distribution, because such a distribution will generally be taxable even though it may economically represent a return of a portion of your investment.
If you are neither a resident nor a citizen of the United States or if you are a foreign entity, distributions (other than Capital Gain Dividends) paid to you by a Fund will generally be subject to a U.S. withholding tax at the rate of 30%, unless a lower treaty rate applies. Gains from the sale or other disposition of your Shares generally are not subject to U.S. taxation, unless you are a nonresident alien individual who is physically present in the U.S. for 183 days or more per year. A Fund may, under certain circumstances, report all or a portion of a dividend as an “interest-related dividend” or a “short-term capital gain dividend,” which would generally be exempt from this 30% U.S. withholding tax, provided certain other requirements are met. Different tax consequences may result if you are a foreign shareholder engaged in a trade or business within the United States or if a tax treaty applies.
Under legislation generally known as “FATCA” (the Foreign Account Tax Compliance Act), a Fund is required to withhold 30% of certain ordinary dividends it pays to shareholders that are foreign entities and that fail to meet prescribed information reporting or certification requirements.
Each Fund (or a financial intermediary, such as a broker, through which a shareholder owns Shares) generally is required to withhold and remit to the U.S. Treasury a percentage of the taxable distributions and sale or redemption proceeds paid to any shareholder who fails to properly furnish a correct taxpayer identification number, who has underreported dividend or interest income, or who fails to certify that he, she or it is not subject to such withholding.
Taxes When Shares are Sold on the Exchange
Any capital gain or loss realized upon a sale of Shares generally is treated as a long-term capital gain or loss if Shares have been held for more than one year and as a short-term capital gain or loss if Shares have been held for one year or less. However, any capital loss on a sale of Shares held for six months or less is treated as long-term capital loss to the extent of Capital Gain Dividends paid with respect to such Shares. Any loss realized on a sale will be disallowed to the extent Shares of a Fund are acquired, including through reinvestment of dividends, within a 61-day period beginning 30 days before and ending 30 days after the disposition of Shares. The ability to deduct capital losses may be limited.
The cost basis of Shares of a Fund acquired by purchase will generally be based on the amount paid for the Shares and then may be subsequently adjusted for other applicable transactions as required by the Code. The difference between the selling price and the cost basis of Shares generally determines the amount of the capital gain or loss realized on the sale or exchange of Shares. Contact the broker through whom you purchased your Shares to obtain information with respect to the available cost basis reporting methods and elections for your account.
Taxes on Purchases and Redemptions of Creation Units
An AP having the U.S. dollar as its functional currency for U.S. federal income tax purposes who exchanges securities for Creation Units generally recognizes a gain or a loss. The gain or loss will be equal to the difference between the value of the Creation Units at the time of the exchange and the exchanging AP’s aggregate basis in the securities delivered, plus the amount of any cash paid for the

55



Creation Units. An AP who exchanges Creation Units for securities will generally recognize a gain or loss equal to the difference between the exchanging AP’s basis in the Creation Units and the aggregate U.S. dollar market value of the securities received, plus any cash received for such Creation Units. The Internal Revenue Service may assert, however, that a loss that is realized upon an exchange of securities for Creation Units may not be currently deducted under the rules governing “wash sales” (for an AP who does not mark-to-market their holdings), or on the basis that there has been no significant change in economic position. APs exchanging securities should consult their own tax advisor with respect to whether wash sale rules apply and when a loss might be deductible.
Any gain or loss realized upon a creation or redemption of Creation Units will be treated as capital or ordinary gain or loss, depending on the circumstances. Any capital gain or loss realized upon redemption of Creation Units is generally treated as long-term capital gain or loss if Shares have been held for more than one year and as a short-term capital gain or loss if Shares have been held for one year or less.
Each Fund may include a payment of cash in addition to, or in place of, the delivery of a basket of securities upon the redemption of Creation Units. Such Fund may sell portfolio securities to obtain the cash needed to distribute redemption proceeds. This may cause such Fund to recognize investment income and/or capital gains or losses that it might not have recognized if it had completely satisfied the redemption in-kind. As a result, such Fund may be less tax efficient if it includes such a cash payment in the proceeds paid upon the redemption of Creation Units.
Taxation of Options Collar Strategy (Risk-Managed Income Funds only)
If positions held by a Fund were treated as “straddles” for federal income tax purposes, or the Fund’s risk of loss with respect to a position was otherwise diminished as set forth in Treasury Regulations, dividends on stocks that are a part of such positions would not constitute qualified dividend income subject to such favorable income tax treatment and would not be eligible for the dividends received deduction for corporate shareholders. In addition, generally, straddles are subject to certain rules that may affect the amount, character and timing of a Fund’s gains and losses with respect to straddle positions by requiring, among other things, that: (1) any loss realized on disposition of one position of a straddle may not be recognized to the extent that the Fund has unrealized gains with respect to the other position in such straddle; (2) the Fund’s holding period in straddle positions be suspended while the straddle exists (possibly resulting in a gain being treated as short-term capital gain rather than long-term capital gain); (3) the losses recognized with respect to certain straddle positions that are part of a mixed straddle and that are not subject to Code Section 1256 be treated as 60% long-term and 40% short-term capital loss; (4) losses recognized with respect to certain straddle positions that would otherwise constitute short-term capital losses be treated as long-term capital losses; and (5) the deduction of interest and carrying charges attributable to certain straddle positions may be deferred.
Net Investment Income Tax
U.S. individuals with income exceeding specified thresholds are subject to a 3.8% tax on all or a portion of their “net investment income,” which includes interest, dividends, and certain capital gains (generally including capital gains distributions and capital gains realized on the sale of Shares). This 3.8% tax also applies to all or a portion of the undistributed net investment income of certain shareholders that are estates and trusts.
Foreign Investments by a Fund (Foreign Funds only)
Interest and other income received by a Fund with respect to foreign securities may give rise to withholding and other taxes imposed by foreign countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes. If as of the close of a taxable year more than 50% of the value of a Fund’s assets consists of certain foreign stock or securities, each such Fund will be eligible to elect to “pass through” to investors the amount of foreign income and similar taxes (including withholding taxes) paid by such Fund during that taxable year. This means that investors would be considered to have received as additional income their respective Shares of such foreign taxes, but may be entitled to either a corresponding tax deduction in calculating taxable income, or, subject to certain limitations, a credit in calculating federal income tax. If a Fund does not so elect, each such Fund will be entitled to claim a deduction for certain foreign taxes incurred by such Fund. A Fund (or its administrative agent) will notify you if it makes such an election and provide you with the information necessary to reflect foreign taxes paid on your income tax return.
The foregoing discussion summarizes some of the possible consequences under current federal tax law of an investment in each Fund. It is not a substitute for personal tax advice. You also may be subject to state and local tax on Fund distributions and sales of Shares. Consult your personal tax advisor about the potential tax consequences of an investment in Shares under all applicable tax laws. For more information, please see the section entitled “Federal Income Taxes” in the SAI.

DISTRIBUTION
The Distributor, Quasar Distributors, LLC, is a broker-dealer registered with the SEC. The Distributor distributes Creation Units for the Funds on an agency basis and does not maintain a secondary market in Shares. The Distributor has no role in determining the policies of the Funds or the securities that are purchased or sold by the Funds. The Distributor’s principal address is 111 East Kilbourn Avenue, Suite 2200, Milwaukee, Wisconsin 53202.
The Board has adopted a Distribution and Service Plan (the “Plan”) pursuant to Rule 12b-1 under the 1940 Act. In accordance with the Plan, each Fund is authorized to pay an amount up to 0.25% of its average daily net assets each year for certain distribution-related activities and shareholder services.
No Rule 12b-1 fees are currently paid by the Funds, and there are no plans to impose these fees. However, in the event Rule 12b-1 fees are charged in the future, because the fees are paid out of Fund assets, over time these fees will increase the cost of your investment and may cost you more than certain other types of sales charges.
PREMIUM/DISCOUNT INFORMATION
Information regarding how often Shares traded on the Exchange at a price above (i.e., at a premium) or below (i.e., at a discount) the NAV of the applicable Fund will be available on the Funds’ website at www.etf.nationwide.com.

FINANCIAL HIGHLIGHTS
The S&P 500 Risk-Managed Income ETF, Dow Jones Risk-Managed Income ETF and Russell 2000 Risk-Managed Income ETF had not commenced operations prior to the date of this Prospectus and therefore do not have financial information.
The financial highlights tables are intended to help you understand each Fund’s financial performance for each Fund’s five most recent fiscal years (or the life of the Fund, if shorter). Certain information reflects financial results for a single Share. The total returns in the tables represent the rate that an investor would have earned or lost on an investment in a Fund (assuming reinvestment of all dividends and distributions). This information has been audited by Cohen & Company, Ltd., the Funds’ independent registered public accounting firm, whose report, along with the Funds’ financial statements, is included in the Funds’ annual report, which is available upon request.
