AAM S&P 500 High Dividend Value ETF (SPDV) Exchange: NYSE ARCA

The Fund uses a “passive management” (or indexing) approach to track the total return performance, before fees and expenses, of the Index. S&P 500 Dividend and Free Cash Flow Yield Index The Index is a rules-based, equal-weighted index that is designed to provide exposure to the constituents of the S&P 500® Index that exhibit both high dividend yield and sustainable dividend distribution characteristics, while maintaining diversified sector exposure. The Index was developed in 2017 by S&P Dow Jones Indices, a division of S&P Global. The S&P 500 Index consists of approximately 500 leading U.S.-listed companies representing approximately 80% of the U.S. equity market capitalization. Construction of the Index begins with the universe of equity securities that are included in the S&P 500 Index. For each equity security in the S&P 500 Index, the security’s dividend yield and free-cash-flow yield (i.e., a company’s cash flow from operations less capital expenditures divided by its market capitalization) are adjusted to account for outliers. If a security’s dividend yield or free-cash-flow yield is in the top or bottom 2.5% of the S&P 500 Index, the dividend yield or free-cash-flow yield, as applicable, for such security is replaced with the dividend yield or free-cash-flow yield of the security nearest to such top or bottom 2.5% threshold. The universe is then screened to keep only equity securities with a positive indicated annual dividend yield (i.e., yield based on a company’s most recent dividend amount) and free-cash-flow yield. The remaining securities are referred to as the “Selection Pool”. For each security in the Selection Pool, the security’s dividend yield and free-cash-flow yield are then scored using a statistical normalization model (i.e., a tool to compare how close each yield is to the average yield for the Selection Pool) to assign a dividend yield score and free-cash-flow yield score from zero to one for each company. The equity securities in the Selection Pool are then ranked by the product of their dividend yield score and free-cash-flow yield score, and the top five scoring securities are selected from each sector (collectively, the “Index Constituents”). The Index uses Standard & Poor’s Global Industry Classification Standards to define companies within one of the following sectors: consumer discretionary, consumer staples, energy, financials, health care, industrials, information technology, materials, real estate, communication services, and utilities. Fewer than five securities may be selected if there are fewer than five securities in the Selection Pool for a given sector. The Index is reconstituted (i.e., Index Constituents are added or deleted and weights are reset to equal-weight) semi-annually after the close of the last business day in January and July. At the time of each reconstitution of the Index, Index Constituents are added or deleted based on company data as of the last business day of December and June, respectively, and the Index Constituents are equally-weighted based on closing prices as of five business days prior to the last business day of the reconstitution month. If an Index Constituent is removed from the S&P 500 Index, such security will simultaneously be removed from the Index. Additions to the Index Constituents only take place during the semi-annual reconstitutions. 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’s investment adviser 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 generally will invest in all of the component securities of the Index in approximately the same proportion 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.
