NATIONWIDE RISK-BASED U.S. EQUITY ETF

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”).

The following table describes the fees and expenses you may pay if you buy, hold, and sell shares of the Fund (“Shares”). This table and the Example below do not include the brokerage commissions that investors may pay on their purchases and sales of Shares.

Annual Fund Operating Expenses	Nationwide Risk-Based U.S. Equity ETF Nationwide Risk-Based U.S. Equity ETF
Management Fees (as a percentage of Assets)	0.30%
Distribution and Service (12b-1) Fees	none
Other Expenses (as a percentage of Assets):	none
Expenses (as a percentage of Assets)	0.30%

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.

Expense Example	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years	Expense Example, with Redemption, 5 Years	Expense Example, with Redemption, 10 Years
Nationwide Risk-Based U.S. Equity ETF \| Nationwide Risk-Based U.S. Equity ETF \| USD ($)	31	97	169	381

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, 2019, the Fund’s portfolio turnover rate was 76% of the average value of its portfolio.

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 60% 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 security selection by risk contribution ranking and the Risk-Weighting Model is to (i) lower the overall volatility of the Index, (ii) increase its Sharpe ratio, and (iii) reduce the 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

The Fund attempts to invest all, or substantially all, of its assets in the component securities that make up the Index. Under normal circumstances, at least 80% of the Fund’s total assets (exclusive of any collateral held from securities lending) will be invested in the component securities of the Index. The Fund expects that, over time, the correlation between the Fund’s performance and that of the Index, before fees and expenses, will be 95% or better.

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 up to 20% of its total assets (exclusive of any collateral held from securities lending) 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.

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.”

•

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.


•	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.


•	Market Risk. The trading prices of equity securities and other instruments fluctuate in response to a variety of factors. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.


•	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.

◦

Mid-Capitalization Investing. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large capitalization stocks or the stock market as a whole.

◦

Small-Capitalization Investing. The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large- or mid-capitalization companies. The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large- or mid-capitalization stocks or the stock market as a whole. There is typically less publicly available information concerning smaller-capitalization companies than for larger, more established companies.

•

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 the inclusion or exclusion of securities 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 its 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.

The following performance information indicates some of the risks of investing in the Fund. The bar chart shows the Fund’s performance for the calendar year 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.

Average Annual Total Returns For the Period Ended December 31, 2018

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. In certain cases, the figure representing “Return After Taxes on Distributions and Sale of Shares” may be higher than the other return figures for the same period. A higher after-tax return results when a capital loss occurs upon redemption and provides an assumed tax deduction that benefits the investor. 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.

NATIONWIDE RISK-BASED INTERNATIONAL EQUITY ETF

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”).

The following table describes the fees and expenses you may pay if you buy, hold, and sell shares of the Fund (“Shares”). This table and the Example below do not include the brokerage commissions that investors may pay on their purchases and sales of Shares.

Annual Fund Operating Expenses	Nationwide Risk-Based International Equity ETF Nationwide Risk-Based International Equity ETF
Management Fees (as a percentage of Assets)	0.42%
Distribution and Service (12b-1) Fees	none
Other Expenses (as a percentage of Assets):	none
Expenses (as a percentage of Assets)	0.42%

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.

Expense Example	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years	Expense Example, with Redemption, 5 Years	Expense Example, with Redemption, 10 Years
Nationwide Risk-Based International Equity ETF \| Nationwide Risk-Based International Equity ETF \| USD ($)	43	135	235	530

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, 2019, the Fund’s portfolio turnover rate was 98% of the average value of its portfolio.

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 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 60% 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 its Sharpe ratio, and (iii) reduce the 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, 2019, the Index included significant exposure to companies in Europe, including Germany and the United Kingdom, and Japan.

The Fund’s Investment Strategy

The Fund attempts to invest all, or substantially all, of its assets in the component securities that make up the Index. Under normal circumstances, at least 80% of the Fund’s total assets (exclusive of any collateral held from securities lending) will be invested in the component securities of the Index and investments that have economic characteristics that are substantially identical to the economic characteristics of such component securities (e.g., depositary receipts). The Fund expects that, over time, the correlation between the Fund’s performance and that of the Index, before fees and expenses, will be 95% or better.

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 up to 20% of its total assets (exclusive of any collateral held from securities lending) 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.

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.”

•

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.

•

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.


•	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.

•

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 (the “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.

In June 2016, the UK held a referendum resulting in a vote in favor of the exit of the UK from the EU (known as “Brexit”). Because of the referendum, Standard & Poor’s (“S&P”) downgraded the UK’s credit rating from “AAA” to “AA” and the EU’s credit rating from “AA+” to “AA” in the days that followed the vote. Other credit ratings agencies have taken similar actions. On March 29, 2017, the UK invoked article 50 of the Lisbon Treaty, notifying the European Council of the UK’s intention to withdraw from the EU by the end of March 2019. However, after two years of negotiating the UK’s withdrawal from the EU, this date has been extended until January 31, 2020. During this period and beyond, 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 a Fund’s investments. Additionally, depreciation of the British pound sterling and/or the euro in relation to the U.S. dollar in anticipation of Brexit would adversely affect Fund investments denominated in British pound sterling and/or the euro, regardless of the performance of the investment.

◦

Risk of Investing in Germany: Investments in German issuers may subject the Fund to legal, regulatory, political, currency, security, and economic risks specific to Germany. Recently, new concerns have emerged in relation to the economic health of the EU, which have led to downward pressure on the earnings of certain financial institutions, including German financial services companies. Secessionist movements, such as the Catalan movement in Spain and the independence movement in Scotland, may have an adverse effect on the German economy. Germany has an export dependent economy and therefore relies heavily on trade with key trading partners, including the Netherlands, China, the U.S., the U.K., France, Italy and other European countries. Germany is dependent on the economies of these other countries, and any change in the price or demand for German exports may have an adverse impact on its economy.

◦

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 Risk. The trading prices of equity securities and other instruments fluctuate in response to a variety of factors. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.


•	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 the inclusion or exclusion of securities 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 its 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.

The following performance information indicates some of the risks of investing in the Fund. The bar chart shows the Fund’s performance for the calendar year 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.

Average Annual Total Returns For the Period Ended December 31, 2018

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. In certain cases, the figure representing “Return After Taxes on Distributions and Sale of Shares” may be higher than the other return figures for the same period. A higher after-tax return results when a capital loss occurs upon redemption and provides an assumed tax deduction that benefits the investor. 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.

NATIONWIDE MAXIMUM DIVERSIFICATION U.S. CORE EQUITY ETF

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”).

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.

Expense Example	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years	Expense Example, with Redemption, 5 Years	Expense Example, with Redemption, 10 Years

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, 2019, the Fund’s portfolio turnover rate was 37% of the average value of its portfolio.

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 December 20, 2019, the minimum market capitalization was US$6.75 billion. Companies in the Index universe are then screened to eliminate securities with insufficient liquidity and relatively new issues (the remaining securities are referred to as the “Eligible Universe”).

Companies in the Eligible Universe 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 eliminated from the Eligible Universe, and the remaining companies are included in the Index (the “Index Constituents”).

The Index Constituents 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, 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% (e.g., if an Index Constituent’s weight is 1% in the Index and 5% in the Cap-Weighted Benchmark, then the Index Constituent’s contribution to the active share of the Index would be 4%).

The MaxDiv Model is also optimized to reduce turnover (e.g., minimum market capitalizations and median value traded are reduced for companies already included in the Index) and to limit 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

The Fund attempts to invest all, or substantially all, of its assets in the component securities that make up the Index. Under normal circumstances, at least 80% of the Fund’s total assets (exclusive of any collateral held from securities lending) will be invested in the component securities of the Index. The Fund expects that, over time, the correlation between the Fund’s performance and that of the Index, before fees and expenses, will be 95% or better.

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 up to 20% of its total assets (exclusive of any collateral held from securities lending) 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.

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.”

•

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.


•	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.


•	Market Risk. The trading prices of equity securities and other instruments fluctuate in response to a variety of factors. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.

•

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 the inclusion or exclusion of securities 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 its 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.

The following performance information indicates some of the risks of investing in the Fund. The bar chart shows the Fund’s performance for the calendar year 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.

Average Annual Total Returns For the Period Ended December 31, 2018

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. In certain cases, the figure representing “Return After Taxes on Distributions and Sale of Shares” may be higher than the other return figures for the same period. A higher after-tax return results when a capital loss occurs upon redemption and provides an assumed tax deduction that benefits the investor. 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.

NATIONWIDE MAXIMUM DIVERSIFICATION EMERGING MARKETS CORE EQUITY ETF

The Nationwide Maximum Diversification Emerging Markets Core Equity ETF (the “Fund”) seeks to track the total return performance, before fees and expenses, of the TOBAM Maximum Diversification Emerging Index (the “Index”).

The following table describes the fees and expenses you may pay if you buy, hold, and sell shares of the Fund (“Shares”). This table and the Example below do not include the brokerage commissions that investors may pay on their purchases and sales of Shares.

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 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, 2019, the Fund’s portfolio turnover rate was 44% of the average value of its portfolio.

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 Emerging Index

The Index is a rules-based index that is designed to create a more diversified equity portfolio of the common and preferred stock (or depositary receipts) of companies in emerging markets 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 2015 by TOBAM S.A.S., the Fund’s index provider.

Construction of the Index begins with the universe of common and preferred stocks (or their depositary receipts) of emerging markets countries with a minimum market capitalization set by the Index rules and adjusted quarterly based on changes to the overall equity market capitalization of the applicable geographic regions. The countries in Asia included in the Index are China, India, Indonesia, Malaysia, Philippines, South Korea, Taiwan, and Thailand. The countries in Europe (including the Middle East) included in the Index are Czech Republic, Greece, Hungary, Poland, Russia, South Africa, and Turkey. The counties in Latin America included in the Index are Brazil, Chile, Colombia, Mexico, and Peru. As of December 20, 2019, the minimum market capitalization was US$1 billion for countries in Europe (including the Middle East) and US$750 million for companies in Asia and Latin America. Companies in the Index universe are then screened to eliminate securities with insufficient liquidity and relatively new issues (the remaining securities are referred to as the “Eligible Universe”). Common and preferred stocks in the Eligible Universe are replaced with their more liquid depositary receipt where such depositary receipts exist.

Companies in the Eligible Universe 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 eliminated from the Eligible Universe, and the remaining companies are included in the Index (the “Index Constituents”).

The Index Constituents 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) 10 times the security’s weight had the Eligible Universe been market capitalization weighted (the “Cap-Weighted Benchmark”). The weight of any individual country cannot exceed five times its weight in the Cap-Weighted Benchmark.

Additionally, 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% (e.g., if an Index Constituent’s weight is 1% in the Index and 5% in the Cap-Weighted Benchmark, then the Index Constituent’s contribution to the active share of the Index would be 4%) and the active share of each country in the Index does not exceed 5 times each country’s respective weight in the Cap-Weighted Benchmark.

The MaxDiv Model is also optimized to reduce turnover (e.g., minimum market capitalizations and median value traded are reduced for companies already included in the Index) and to limit 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. As of September 30, 2019, the Index included significant exposure to companies in China, India, and Taiwan.

The Fund’s Investment Strategy

The Fund attempts to invest all, or substantially all, of its assets in the component securities that make up the Index. Under normal circumstances, at least 80% of the Fund’s total assets (exclusive of any collateral held from securities lending) will be invested in the component securities of the Index and investments that have economic characteristics that are substantially identical to the economic characteristics of such component securities (e.g., depositary receipts). The Fund expects that, over time, the correlation between the Fund’s performance and that of the Index, before fees and expenses, will be 95% or better.

The Fund will 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. However, the Fund may 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, when the Fund’s sub-adviser believes it is in the best interests of the Fund (e.g., when replicating the Index does not involve practical difficulties or substantial costs).

The Fund generally may invest up to 20% of its total assets (exclusive of any collateral held from securities lending) 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.

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.”

•

Capital Controls and Sanctions Risk. Economic conditions, such as volatile currency exchange rates and interest rates, political events, military action and other conditions may, without prior warning, lead to foreign government intervention (including intervention by the U.S. government with respect to foreign governments, economic sectors, foreign companies and related securities and interests) and the imposition of capital controls and/or sanctions, which may also include retaliatory actions of one government against another government, such as seizure of assets. Capital controls and/or sanctions include the prohibition of, or restrictions on, the ability to transfer currency, securities or other assets. Capital controls and/or sanctions may also impact the ability of the Fund to buy, sell or otherwise transfer securities or currency, negatively impact the value and/or liquidity of such instruments, adversely affect the trading market and price for Shares, and cause the Fund to decline in value.

•

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.

•

Emerging Markets Risk. The Fund invests primarily in companies organized in emerging market nations. Investments in securities and instruments traded in developing or emerging markets, or that provide exposure to such securities or markets, can involve additional risks relating to political, economic, or regulatory conditions not associated with investments in U.S. securities and instruments or investments in more developed international markets. Such conditions may impact the ability of the Fund to buy, sell or otherwise transfer securities, adversely affect the trading market and price for Shares and cause the Fund to decline in value.

•

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.


•	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.

•

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 of Investing in China: Investments in Chinese issuers subject the Fund to risks specific to China. China may be subject to considerable degrees of economic, political and social instability. China is a developing market and demonstrates significantly higher volatility from time to time in comparison to developed markets. Over the past 25 years, the Chinese government has undertaken reform of economic and market practices and is expanding the sphere of private ownership of property in China. However, Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies resulting from governmental influence, a lack of publicly available information and/or political and social instability. Internal social unrest or confrontations with other neighboring countries, including military conflicts in response to such events, may also disrupt economic development in China and result in a greater risk of currency fluctuations, currency convertibility, interest rate fluctuations and higher rates of inflation. Export growth continues to be a major driver of China’s rapid economic growth. Reduction in spending on Chinese products and services, institution of tariffs or other trade barriers, or a downturn in any of the economies of China’s key trading partners may have an adverse impact on the Chinese economy.

◦

Risks of Investing in India: Investments in Indian issuers involve risks that are specific to India, including legal, regulatory, political and economic risks. Political and legal uncertainty, greater government control over the economy, currency fluctuations or blockage and the risk of nationalization or expropriation of assets may result in higher potential for losses. The securities markets in India are relatively underdeveloped and may subject the Fund to higher transaction costs or greater uncertainty than investments in more developed securities markets.

◦

Risks of Investing in Taiwan: Investments in Taiwanese issuers may subject the Fund to risks. Taiwan is a small island state with few raw material resources and limited land area and is reliant on imports for its commodity needs. Any fluctuations or shortages in the commodity markets could have a negative impact on the Taiwanese economy. Also, continued labor outsourcing may adversely affect the Taiwanese economy. Taiwan’s economy is intricately linked with economies of Asian countries that have experienced over-extensions of credit, frequent and pronounced currency fluctuations, currency devaluations, currency repatriation, rising unemployment and fluctuations in inflation. The Taiwanese economy is dependent on the economies of Japan and China, as well as the United States, and negative changes in their economies or a reduction in purchases by any of them of Taiwanese products and services would likely have an adverse impact on the Taiwanese economy. Taiwan’s geographic proximity to China and Taiwan’s history of political contention with China have resulted in ongoing tensions with China, including the risk of war with China. These tensions may materially affect the Taiwanese economy and securities markets.

•

Geopolitical Risk. Some countries and regions in which the Fund invests have experienced security concerns, war or threats of war and aggression, terrorism, economic uncertainty, natural and environmental disasters and/or systemic market dislocations that have led, and in the future may lead, to increased short-term market volatility and may have adverse long-term effects on the U.S. and world economies and markets generally, each of which may negatively impact the Fund’s investments.


•	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.

◦

Mid-Capitalization Investing. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large capitalization stocks or the stock market as a whole.

◦

Small-Capitalization Investing. The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large- or mid-capitalization companies. The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large- or mid-capitalization stocks or the stock market as a whole. There is typically less publicly available information concerning smaller-capitalization companies than for larger, more established companies.


•	Market Risk. The trading prices of equity securities and other instruments fluctuate in response to a variety of factors. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.

•

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 the inclusion or exclusion of securities 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 its 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 information for the Fund is not included because the Fund did not have a full calendar year of performance prior to the date of this Prospectus. In the future, performance information for the Fund will be presented in this section. Updated performance information is available on the Fund’s website at www.etf.nationwide.com.

NATIONWIDE MAXIMUM DIVERSIFICATION INTERNATIONAL CORE EQUITY ETF

The Nationwide Maximum Diversification International Core Equity ETF (the “Fund”) seeks to track the total return performance, before fees and expenses, of the TOBAM Maximum Diversification All World Developed ex North America Index (the “Index”).

The following table describes the fees and expenses you may pay if you buy, hold, and sell shares of the Fund (“Shares”). This table and the Example below do not include the brokerage commissions that investors may pay on their purchases and sales of Shares.

Annual Fund Operating Expenses	Nationwide Maximum Diversification International Core Equity ETF Nationwide Maximum Diversification International Core Equity ETF
Management Fees (as a percentage of Assets)	0.44%
Distribution and Service (12b-1) Fees	none
Other Expenses (as a percentage of Assets):	none	^[1]
Expenses (as a percentage of Assets)	0.44%

[1]	Estimated for the current fiscal year.

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.

Expense Example	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years

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.

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 All World Developed ex North America Index

The Index is a rules-based index that is designed to create a more diversified equity portfolio of the common and preferred stock (or depositary receipts) of large and mid-capitalization companies in developed markets outside the United States and Canada 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 common and preferred stocks (or their depositary receipts) of companies in developed markets outside the United States and Canada with a minimum market capitalization set by the Index rules and adjusted quarterly based on changes to the overall equity market capitalization of the applicable geographic regions. The countries in Asia included in the Index are Australia, Hong Kong, Japan, New Zealand, and Singapore. The countries in Europe (including the Middle East) included in the Index are Austria, Belgium, Denmark, Finland, France, Germany, Ireland, Israel, Italy, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland, and the United Kingdom. As of December 20, 2019, the minimum market capitalization was US$1.75 billion for companies in Asia (including Australia and New Zealand) and US$3 billion for companies in Europe and the Middle East. Companies in the Index universe are then screened to eliminate securities with insufficient liquidity and relatively new issues (the remaining securities are referred to as the “Eligible Universe”). Common and preferred stocks in the Eligible Universe are replaced with their more liquid depositary receipt where such depositary receipts exist.

Companies in the Eligible Universe 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 eliminated from the Eligible Universe, and the remaining companies are included in the Index (the “Index Constituents”).

The Index Constituents 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% (3.0% for companies in the United Kingdom) or (ii) 20 times the security’s weight had the Eligible Universe been market capitalization weighted (the “Cap-Weighted Benchmark”). The weight of all companies in each of Europe and Asia cannot exceed by more than 10% the weight of companies in each such region in the Cap-Weighted Benchmark.

Additionally, 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% (e.g., if an Index Constituent’s weight is 1% in the Index and 5% in the Cap-Weighted Benchmark, then the Index Constituent’s contribution to the active share of the Index would be 4%).

The MaxDiv Model is also optimized to reduce turnover (e.g., minimum market capitalizations and median value traded are reduced for companies already included in the Index).

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. As of September 30, 2019, the Index included significant exposure to companies in Europe and Japan.

The Fund’s Investment Strategy

The Fund attempts to invest all, or substantially all, of its assets in the component securities that make up the Index. Under normal circumstances, at least 80% of the Fund’s total assets (exclusive of any collateral held from securities lending) will be invested in the component securities of the Index and investments that have economic characteristics that are substantially identical to the economic characteristics of such component securities (e.g., depositary receipts). The Fund expects that, over time, the correlation between the Fund’s performance and that of the Index, before fees and expenses, will be 95% or better.

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 up to 20% of its total assets (exclusive of any collateral held from securities lending) 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.

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.”

•

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.

•

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.


•	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.

•

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 (the “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.

In June 2016, the UK held a referendum resulting in a vote in favor of the exit of the UK from the EU (known as “Brexit”). Because of the referendum, Standard & Poor’s (“S&P”) downgraded the UK’s credit rating from “AAA” to “AA” and the EU’s credit rating from “AA+” to “AA” in the days that followed the vote. Other credit ratings agencies have taken similar actions. On March 29, 2017, the UK invoked article 50 of the Lisbon Treaty, notifying the European Council of the UK’s intention to withdraw from the EU by the end of March 2019. However, after two years of negotiating the UK’s withdrawal from the EU, this date has been extended until January 31, 2020. During this period and beyond, 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 a Fund’s investments. Additionally, depreciation of the British pound sterling and/or the euro in relation to the U.S. dollar in anticipation of Brexit would adversely affect Fund investments denominated in British pound sterling and/or the euro, regardless of the performance of the investment.

◦

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.

◦

Mid-Capitalization Investing. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large capitalization stocks or the stock market as a whole.


•	Market Risk. The trading prices of equity securities and other instruments fluctuate in response to a variety of factors. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.

•

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 the inclusion or exclusion of securities 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.


•	New Fund Risk. The Fund is a recently organized, diversified management investment company with no operating history. As a result, prospective investors have no track record or history on which to base their investment decision.

•

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 its 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.
