Before you invest, you may want to review the Fund’s prospectus and Statement of Additional Information (SAI), which contain more information about the Fund and its risks. The current prospectus and SAI, each dated December 31, 2024, as supplemented from time to time, are incorporated by reference into this Summary Prospectus. You can find the Fund’s prospectus, reports to shareholders, and other information about the Fund online at videntam.com/fund-literature. You can also get this information at no cost by calling 1-800-617-0004 or by sending an e-mail request to ETF@usbank.com.

The following table describes the fees and expenses you may pay if you buy, hold, and sell shares of the Fund (“Shares”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below.

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

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, 2024, the Fund’s portfolio turnover rate was 202% of the average value of its portfolio.

The Vident Core U.S. Bond IndexTM seeks to improve the overall mix of credit quality, interest rate and yield as compared to traditional U.S. core bond indices. The Index diversifies interest rate and credit risks across all core U.S. bond sectors, including U.S. Treasuries, U.S. agency securities, U.S. agency mortgage-backed securities (“MBS”), and investment-grade corporate bonds, as well as non-core fixed income sectors such as high-yield corporate bonds (also known as “junk bonds”) and Treasury Inflation-Protected Securities (“TIPS”). While diversification among sectors is an important factor that will drive the risk/return profile of the strategy, another source of risk management is derived from the rules-based process that systematically over- or under-weights each sector based on valuations of each sector, historical relative valuations across sectors, sector default rates, and other quantitative factors. Within the investment grade and high yield corporate sectors, the strategy seeks to improve corporate bond exposures by screening for

companies with relatively stronger leadership, governance, and creditworthiness factors. Within each sector, individual bonds are weighted based on a combination of yield, duration (i.e., interest rate sensitivity), creditworthiness, leadership, and governance factors, rather than amount of debt/bonds outstanding. The Index also seeks to improve liquidity by eliminating small issues and non-U.S. issuers.

The Index limits exposure to each of the high-yield corporate bonds and TIPS sectors to 20% and 15% of the Index, respectively. The Index will generally have an effective duration of three to seven years and will generally have an average credit quality of investment grade.

All rules are systematized and rely on data available at the end of each rebalancing period. The Index is rebalanced monthly and reconstituted quarterly in January, April, July, and October. As of November 29, 2024, the Index was comprised of 239 component securities.

The Fund attempts to invest all, or substantially all, of its assets in the bonds that make up the Index. The Fund expects to use a “replication” strategy to achieve its investment objective, meaning it may invest in all of the component securities of the Index, but may, when the adviser believes it is in the best interests of the Fund, 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.

The Fund may utilize the “To Be Announced” (“TBA”) market for MBS investments. The TBA market allows investors to gain exposure to MBS with certain broad characteristics (maturity, coupon, age) without taking delivery of the actual securities until the settlement day which is once every month. In addition, the Fund may utilize the TBA roll market, in which one sells, in the TBA market, the security for current month settlement, while simultaneously committing to buy the same TBA security for next month settlement. The Fund may utilize the TBA roll market for extended periods of time without taking delivery of the physical securities.

The principal risks of investing in the Fund are summarized below. The principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund. Some or all of these risks may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and/or ability to meet its objectives. For more information about the risks of investing in the Fund, see the section in the Fund’s Prospectus titled “Additional Information About the Funds.”

•Call Risk. During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” or repay the security before its stated maturity, and the Fund may have to reinvest the proceeds at lower interest rates, resulting in a decline in the Fund’s income.

◦Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

◦Cash Redemption Risk. The Fund’s investment strategy may require it to redeem shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have

◦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. There can be no assurance that an active trading market for such Shares will develop or be maintained. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares, and this could lead to differences between the market price of the Shares and the underlying value of those Shares.

•Extension Risk. During periods of rising interest rates, certain debt obligations will be paid off substantially more slowly than originally anticipated and the value of those securities may fall sharply, resulting in a decline in the Fund’s income and potentially in the value of the Fund’s investments.

•Government Obligations Risk. No assurance can be given that the U.S. government will provide financial support to U.S. government-sponsored agencies or instrumentalities where it is not obligated to do so by law, such as the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Mortgage Corporation (“Freddie Mac”). Securities issued by Fannie Mae and Freddie Mac have historically been supported only by the discretionary authority of the U.S. government. While the U.S. government provides financial support to various U.S. government-sponsored agencies and instrumentalities, such as Fannie Mae and Freddie Mac, no assurance can be given that it will always do so. In September 2008, at the direction of the U.S. Department of the Treasury, Fannie Mae and Freddie Mac were placed into conservatorship under the Federal Housing Finance Agency (“FHFA”), an independent regulator, and they remain in such status as of the date of this Prospectus. The U.S. government also took steps to provide additional financial support to Fannie Mae and Freddie Mac.

•High-Yield Securities Risk. High-yield securities (also known as “junk bonds”) carry a greater degree of risk and are considered speculative by the major credit rating agencies. High-yield securities may be issued by companies that are restructuring, are smaller and less creditworthy, or are more highly indebted than other companies. This means that they may have more difficulty making scheduled payments of principal and interest. Changes in the value of high-yield securities are influenced more by changes in the financial and business position of the issuing company than by changes in interest rates when compared to investment grade securities. High-yield securities have greater volatility because there is less certainty that principal and interest payments will be made as scheduled. The Fund’s investments in high-yield securities expose it to a substantial degree of credit risk. These investments are considered speculative under traditional investment standards. Prices of high-yield securities will rise and fall primarily in response to actual or perceived changes in the issuer's financial health, although changes in market interest rates also will affect prices. High-yield securities may experience reduced liquidity and sudden and substantial decreases in price.

•Interest Rate Risk. An increase in interest rates may cause the value of fixed-income securities held by the Fund to decline. Securities with longer durations tend to be more sensitive to interest rate changes, usually making them more volatile than securities with shorter durations. For example, the price of a bond with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Generally, the longer the maturity and duration of a bond, the more sensitive the bond is to interest rate risk.

•Market Risk. The trading prices of debt 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.

•Mortgage- and Asset-Backed Securities Risk. The Fund may invest in U.S. government agency-backed mortgage- and asset-backed securities. Mortgage- and asset-backed securities are subject to interest rate risk. Modest movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain types of these securities. When interest rates fall, mortgage- and asset-backed securities may be subject to prepayment risk. When interest rates rise, certain types of mortgage- and asset-backed securities are subject to extension risk. Mortgage- and asset-backed securities can also be subject to the risk of default on the underlying residential or commercial mortgage(s) or other assets.

•Passive Investment Risk. The Fund invests in the securities included in, or representative of, the Index regardless of their investment merit. The Fund does not attempt to outperform the Index or take defensive positions in declining markets. As a result, the Fund’s performance may be adversely affected by a general decline in the market segments relating to the Index.

•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.

•Prepayment Risk. This is the risk that a borrower will prepay some or the entire principal owed to the Fund. If that happens, the Fund may have to replace the security by investing the proceeds in a security with a lower yield. This could reduce the share price and income distributions of the Fund.

•TBA Securities and Rolls Risk. TBA transactions are subject to increased credit risk and increased overall investment exposure. TBA rolls involve the risk that the Fund’s counterparty will be unable to deliver the mortgage-backed securities underlying the TBA roll at the fixed time. If the buyer files for bankruptcy or becomes insolvent, the buyer or its representative may ask for and receive an extension of time to decide whether to enforce the Fund’s repurchase obligation. In addition, the Fund earns interest by investing the transaction proceeds during the roll period. TBA roll transactions may have the effect of creating leverage in the Fund’s portfolio.

•Tracking Error Risk. As with all index funds, the performance of the Fund and the Index may differ from each other for a variety of reasons. For example, the Fund incurs operating expenses and portfolio transaction costs not incurred by the Index. In addition, the Fund may not be fully invested in the securities of the Index at all times or may hold securities not included in the Index.

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 years ended December 31. The table illustrates how the Fund’s average annual returns for the 1-year, 5-year, and since inception periods compare with those of the FTSE US Broad Investment Grade Bond Index, a broad measure of U.S. bond market performance, and the blended returns of the Vident Core U.S. Bond Index and Vident Core U.S. Bond Strategy Index, the indexes tracked by the Fund during the applicable period. 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.videntam.com.

For the year-to-date period ended September 30, 2024, the Fund’s total return was 4.46%.

1 Effective January 6, 2016, the Fund’s investment objective changed to track the performance, before fees and expenses, of the Vident Core U.S. Bond Index. Prior to January 6, 2016, the Fund’s investment objective was to track the price and total return performance, before fees and expenses, of the Vident Core U.S. Bond Strategy Index. Performance shown for periods prior to January 6, 2016, is that of the Vident Core U.S. Bond Strategy Index.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates during the period covered by the table above and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns shown are not relevant to investors who hold their Shares through tax-deferred arrangements such as an individual retirement account (“IRA”) or other tax-advantaged accounts. 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.


Adviser:			Vident Asset Management

Portfolio Managers:			Jim Iredale, CFA, Senior Portfolio Manager for Vident, has been a portfolio manager of the Fund since April 2015.

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

The Fund issues and redeems Shares at NAV only in large blocks known as “Creation Units,” which only APs (typically, broker-dealers) may purchase or redeem. The Fund generally issues and redeems Creation Units in exchange for a portfolio of securities and/or a designated amount of U.S. cash.

Investors may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase Shares (bid) and the lowest price a seller is willing to accept for Shares (ask) when buying or selling Shares in the secondary market (the “bid-ask spread”). Recent information about the Fund, including its NAV, market price, premiums and discounts, and bid-ask spreads is available on the Fund’s website at www.videntam.com.

Fund distributions are generally taxable as ordinary income or capital gains (or a combination), unless your investment is in an IRA or other tax-advantaged account. Distributions on investments made through tax-deferred arrangements may be taxed later upon withdrawal of assets from those accounts.

If you purchase Shares through a broker-dealer or other financial intermediary (such as a bank) (an “Intermediary”), the Adviser or its affiliates may pay Intermediaries for certain activities related to the Fund, including participation in activities that are designed to make Intermediaries more knowledgeable about exchange traded products, including the Fund, or for other activities, such as marketing, educational training or other initiatives related to the sale or promotion of Shares. These payments may create a conflict of interest by influencing the Intermediary and your salesperson to recommend the Fund over another investment. Any such arrangements do not result in increased Fund expenses. Ask your salesperson or visit the Intermediary’s website for more information.
