Nationwide Maximum Diversification Emerging Markets Core Equity ETF (MXDE) Exchange: NYSE ARCA

DELISTED - 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.
