The Fund utilizes both fundamental analysis and proprietary quantitative frameworks that help inform the investment decision-making process regarding strategic investment opportunities. The Fund may allocate among major equity asset classes and sectors, within the Underlying Funds, of the U.S., foreign and emerging markets equity of any capitalization. It may further allocate, including by not limited to: domestic investment-grade bonds, domestic high yield bonds (also known as junk bonds), foreign investment-grade, commodities, precious metals and money market funds during periods of weakness in equity markets. It will generally have some level of investment in equity assets classes but there is no stated limit on the percentage of assets the fund can invest in a particular Underlying Fund or the percentage of assets the fund will allocate to any one asset class, and at times the fund may focus on a small number of Underlying Funds or asset classes and may be non-diversified across asset classes and/or Underlying Funds. Under normal circumstances, the Fund will seek to fully participate in the positive upside of equity markets. The Fund will seek to reduce risk when fundamental and quantitative frameworks identify weakness within various asset classes and/or sectors and will tactically alternate various Underlying Funds. Summit Global Investments, LLC (the Adviser) may make tactical exposure changes for various other reason. For example, the Adviser may attempt to lower the Funds market risk by investing in the Underlying Funds that seek to lower the overall volatility of the Funds portfolio as compared to the S&P 500 Index. Volatility is a statistical measurement of the magnitude of up and down fluctuations in the value of a financial instrument or index. In addition, the Adviser reviews the idiosyncratic risks associated with each of the Underlying Funds and if these risks are deemed elevated with increased downside risks the Adviser may make changes to the Underlying Funds. The Adviser selects the Underlying Funds for the Fund that it anticipates will produce a portfolio with less volatility with more capital protection and consistent returns. While the Adviser attempts to manage the Funds various risks, such as volatility and downside risks, there is no guarantee that the strategy will be successful or that the Funds portfolio will not experience periods of volatility and loss. The Adviser may evaluate how corporate management executes the objective of the Underlying Fund through examination of the Underlying Funds proxy voting records, prospectus and other reports. The methods that the Underlying Funds use may vary. The Fund may focus its investments in a particular industry or sector for the purpose of capitalizing due to significant changes in market conditions or geopolitical conditions. The Fund may sell one or more of the Underlying Funds if the Adviser identifies fundamental, legal or other risks and/or if the risk/return ranking declines due to increasing risk and/or decreasing return potential. The Fund may also decrease weight in an investment for risk control purposes. Additionally, the Fund may seek to increase its income by lending portfolio securities. The Fund has elected to be, and intends to qualify each year for treatment as, a regulated investment company (RIC) under Subchapter M of Subtitle A, Chapter 1, of the Internal Revenue Code of 1986, as amended (the Code). Semi-Transparent Actively-Managed ETF with Portfolio Reference Basket Structure. The Fund is an actively-managed, semi-transparent ETF. Unlike traditional ETFs, which generally publish their portfolio holdings on a daily basis, the Fund discloses a portfolio transparency substitutethe Portfolio Reference Basketand certain related information about the Portfolio Reference Basket relative to the Funds actual portfolio (Actual Portfolio) holdings (the Portfolio Reference Basket Disclosures), which are intended to help keep the market price of the Funds Shares trading at or close to the underlying net asset value (NAV) per Share of the Fund. While the Portfolio Reference Basket includes all of the Funds holdings, it is not the Funds Actual Portfolio because the holdings will be weighted differently, subject to a minimum weightings overlap of 90% with the Funds Actual Portfolio at the beginning of each trading day. The Fund also discloses the maximum deviation between the weightings of the specific securities in the Portfolio Reference Basket and the weightings of those specific securities in the Actual Portfolio, as well as between the weighting of the respective cash positions (the Guardrail Amount). The Guardrail Amount is intended to ensure that no individual security in the Portfolio Reference Basket will be overweighted or underweighted by more than the publicly disclosed percentage when compared to the actual weighting of each security within the Actual Portfolio as of the beginning of each trading day. The Fund is actively-managed and does not seek to track an index. Show less
