SGI U.S. Large Cap Core ETF SUMMARY SECTION

The SGI U.S. Large Cap Core ETF (for this section only, the “Fund”) seeks to provide long-term capital appreciation.

This table describes the fees and expenses that 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 Fund Shares.

Annual Fund Operating Expenses	SGI U.S. Large Cap Core ETF SGI U.S. Large Cap Core ETF Shares
Management Fees	0.85%
Distribution (12b-1) Fees	none
Other Expenses	none	^[1]
Total Annual Fund Operating Expenses	0.85%

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 hold or redeem all of your Shares at the end of those periods. The Example also assumes that: (1) your investment has a 5% return each year, and (2) 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 Fund 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. No portfolio turnover rate is provided for the Fund because the Fund had not commenced operations prior to the date of this Prospectus.

The Fund is an actively-managed exchange-traded fund (“ETF”) and invests in securities of affiliated and unaffiliated ETFs and open-end mutual funds (collectively, “Underlying Funds”). 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 Fund’s market risk by investing in the Underlying Funds that seek to lower the overall volatility of the Fund’s 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 Fund’s various risks, such as volatility and downside risks, there is no guarantee that the strategy will be successful or that the Fund’s portfolio will not experience periods of volatility and loss.

Some of the Underlying Funds may or may not have processes that include environmental, social, and/or governance (“ESG”) considerations as part of their investment strategy. The Adviser may evaluate how corporate management executes the objective of the Underlying Fund through examination of the Underlying Fund’s 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.

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 substitute—the “Portfolio Reference Basket”—and certain related information about the Portfolio Reference Basket relative to the Fund’s actual portfolio (“Actual Portfolio”) holdings (the “Portfolio Reference Basket Disclosures”), which are intended to help keep the market price of the Fund’s 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 Fund’s holdings, it is not the Fund’s Actual Portfolio because the holdings will be weighted differently, subject to a minimum weightings overlap of 90% with the Fund’s 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.

Loss of money is a risk of investing in the Fund. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The Fund's 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. Different risks may be more significant at different times depending on market conditions or other factors.

●

Affiliated Fund Risk. Affiliated fund risk is the risk that the Adviser may select investments for the Fund based on its own financial interests rather than the Fund’s interests. The Adviser may be subject to potential conflicts of interest in selecting the Underlying Funds because the fees paid to the Adviser by some affiliated Underlying Funds may be higher than other Underlying Funds or the Underlying Funds may be in need of assets to enhance their appeal to other investors, liquidity and trading and/or to enable them to carry out their investment strategies. However, the Adviser is a fiduciary to the Fund and is legally obligated to act in the Fund’s best interest when selecting Underlying Funds.

●

Currency Risk. Underlying Funds that invest in foreign securities are subject to currency risk associated with securities that trade or are denominated in currencies other than the U.S. dollar and that may be affected by fluctuations in currency exchange rates. An increase in the strength of the U.S. dollar relative to a foreign currency may cause the U.S. dollar value of an investment in that country to decline. Foreign currencies also are subject to risks caused by inflation, interest rates, budget deficits and low savings rates, political factors and government controls.

●

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the Underlying Funds, the Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, the Underlying Funds, and the Underlying Fund’s third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund, the Underlying Funds, or their respective investment advisers. Successful cyber-attacks or other cyber-failures or events affecting the Fund, the Underlying Funds, or third-party service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund or Underlying Funds invest are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

●

Dividend-Paying Securities Risk. Underlying Funds that invest in dividend-paying securities may be subject to the risk that the company issuing such securities may fail and have to decrease or eliminate its dividend. In such an event, an Underlying Fund, and in turn the Fund, may not only lose the dividend payout but the stock price of the company may fall.

●

Emerging Markets Risk. The Fund may invest in companies organized in emerging market countries. Investment in emerging market securities involves greater risk than that associated with investment in foreign securities of developed foreign countries. These risks include volatile currency exchange rates, periods of high inflation, increased risk of default, greater social, economic and political uncertainty and instability, less governmental supervision and regulation of securities markets, weaker auditing and financial reporting standards, lack of liquidity in the markets, and the significantly smaller market capitalizations of emerging market issuers. The information available about an emerging market issuer may be less reliable than for comparable issuers in more developed capital markets.

●

Environmental, Social and Governance Investing Risk. ESG investing risk is the risk stemming from the ESG factors that some Underlying Funds may apply in selecting securities. Some Underlying Funds may screen out particular companies that do not meet their ESG criteria. This may affect the Underlying Funds’ and the Fund’s exposure to certain companies or industries and cause the Underlying Funds to forego certain investment opportunities. The Underlying Funds’ results may be lower than other funds that do not use ESG ratings and/or screen out certain companies or industries. Certain Underlying Funds may screen out companies that they believe may have higher downside risk and lower ESG ratings, but investors may differ in their views of ESG characteristics. As a result, the Underlying Funds may invest in companies that do not reflect the beliefs and values of any particular investor.

●

Equity Risk. The Underlying Funds’ investments in common stock are subject to market, economic and business risks that will cause their price to fluctuate over time. Therefore, an investment in the Fund may be more suitable for long-term investors who can bear the risk of these fluctuations. In the event an issuer is liquidated or declares bankruptcy, the claims of owners of bonds and preferred stock take precedence over the claims of those who own common stock.

●

ETF Risk. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks: “Authorized Participants, Market Makers and Liquidity Providers Concentration Risk,” “Cash Transactions Risk,” “ Limitations of Intraday Indicative Value (IIV) Risk,” “Secondary Market Trading Risk,” and “Shares May Trade at Prices Other Than NAV Risk.”

○

Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors and 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, Fund 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. These events, among others, may lead to the Fund Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Fund Shares. Further, the Fund is utilizing a novel and unique structure, which may affect the number of entities willing to act as APs, market makers and/or liquidity providers.

○

Cash Transactions Risk. Unlike traditional ETFs, the securities in the Fund’s basket of securities exchanged for a Creation Unit will not correspond pro rata to the positions in the Fund’s portfolio, and the Fund may effect its creations and redemptions partially or wholly for cash rather than on an in-kind basis. Because of this, the Fund may incur costs such as brokerage costs or be unable to realize certain tax benefits associated with in-kind transfers of portfolio securities that may be realized by other ETFs. These costs may decrease the Fund’s NAV to the extent that the costs are not offset by a transaction fee payable by an AP. Shareholders may be subject to tax on gains they would not otherwise have been subject to and/or at an earlier date than if the Fund had effected redemptions wholly on an in-kind basis.

○

Limitations of Intraday Indicative Value (IIV) Risk. The Exchange or a market data vendor intends to disseminate the approximate per share value of the Fund’s Portfolio Reference Basket every 15 seconds (the “intraday indicative value” or “IIV”). The IIV should not be viewed as a “real-time” update of the NAV per share of the Fund because (i) the IIV is not be calculated in the same manner as the NAV, which is computed once a day, generally at the end of the business day, (ii) the calculation of NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV, (iii) unlike the calculation of NAV, the IIV does not take into account Fund expenses, and (iv) the IIV is based on the Portfolio Reference Basket and not on the Fund’s Actual Portfolio. The Fund, the Adviser , Sub-Adviser and their affiliates are not involved in, or responsible for, any aspect of the calculation or dissemination of the Fund’s IIV, and the Fund, the Adviser, Sub-Adviser and their affiliates do not make any warranty as to the accuracy of these calculations.

○

Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, the Nasdaq Stock Market LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. Trading may be halted because of market conditions or for reasons that, in the view of the Exchange, make trading in the Fund inadvisable. These may include: (a) the extent to which trading is not occurring in the securities and/or the financial instruments composing the Portfolio Reference Basket and/or Actual Portfolio; or (b) whether other unusual conditions or circumstances detrimental to the maintenance of a fair and orderly market are present. During periods of market stress, 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). This risk is heightened in times of market volatility or periods of steep market declines.

○

Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although the Portfolio Reference Basket structure is intended to provide market participants with enough information to allow for an effective arbitrage mechanism that will help to keep the market price of the Fund’s Shares at or close to the Fund’s NAV, there is a risk that market prices for Fund Shares will vary significantly from the Fund’s NAV. This risk is heightened in times of market volatility or periods of steep market declines. This risk may be greater for the Fund than for traditional ETFs that disclose their full portfolio holdings on a daily basis because the publication of the Portfolio Reference Basket does not provide the same level of transparency as the daily publication of the actual portfolio by a traditional ETF. This could cause the Fund’s Shares to have wider bid/ask spreads and larger premiums/discounts than traditional ETFs using the same or similar investment strategies.

●

Fixed Income Securities Risk. To the extent the Fund invests in Underlying Funds that invest in fixed income securities, the Fund will be subject to fixed income securities risks. While fixed income securities normally fluctuate less in price than stocks, there have been extended periods of increases in interest rates that have caused significant declines in fixed income securities prices. The values of fixed income securities may be affected by changes in the credit rating or financial condition of their issuers. Generally, the lower the credit rating of a security, the higher the degree of risk as to the payment of interest and return of principal.

Credit Risk. The issuer of a fixed income security may not be able to make interest and principal payments when due. Generally, the lower the credit rating of a security, the greater the risk that the issuer will default on its obligation. An Underlying Fund could also be delayed or hindered in its enforcement of rights against an issuer, guarantor, or counterparty.

Duration Risk. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities.

Income Risk. The Fund’s income could decline due to falling market interest rates. In a falling interest rate environment, the Fund may be required to invest in Underlying Funds that invest their assets in lower-yielding securities. Because interest rates vary, it is impossible to predict the income or yield of the Fund for any particular period.

Interest Rate Risk. The value of the Fund or an Underlying Fund may fluctuate based upon changes in interest rates and market conditions. As interest rates increase, the value of an Underlying Fund’s income-producing investments may go down. For example, bonds tend to decrease in value when interest rates rise. Debt obligations with longer maturities typically offer higher yields, but are subject to greater price movements as a result of interest rate changes than debt obligations with shorter maturities. Changing interest rates may have unpredictable effects on the markets and an Underlying Fund’s investments and may also affect the liquidity of fixed income securities and instruments held by an Underlying Fund.

Prepayment Risk. The Fund may invest in Underlying Funds that invest in securities that are subject to fluctuations in yield, due to prepayment rates that may be faster or slower than expected.

Rating Risk. If a rating agency gives a debt security a lower rating, the value of the debt security will decline because investors will demand a higher rate of return.

●

Foreign Custody Risk. An Underlying Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Underlying Fund’s custodian (each a “Foreign Custodian”). Some Foreign Custodians may be recently organized or new to the foreign custody business. In some countries, Foreign Custodians may be subject to little or no regulatory oversight over or independent evaluation of their operations. Further, the laws of certain countries may place limitations on the Underlying Fund’s ability to recover its assets if a Foreign Custodian enters bankruptcy. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Custody services in emerging market countries are very often undeveloped and may be considerably less well-regulated than in more developed countries, and thus may not afford the same level of investor protection as would apply in developed countries. Emerging market countries are countries that major international financial institutions, such as the World Bank, generally consider to be less economically mature than developed nations. Emerging market countries can include every nation in the world except the United States, Canada, Japan, Australia, New Zealand and most countries located in Western Europe.

●

Foreign Securities Risk. Underlying Funds that invest in foreign securities may be subject to special risks, including, but not limited to, currency exchange rate volatility, political, social or economic instability, less publicly available information, less stringent investor protections and differences in taxation, auditing and other financial practices. Investments in emerging market securities by Underlying Funds are subject to higher risks than those in developed countries because there is greater uncertainty in less established markets and economies.

●

Growth Risk. If an Underlying Fund adviser’s perceptions of a company’s growth potential are wrong, the securities purchased by that Underlying Fund may not perform as expected, thereby reducing the Underlying Fund’s and the Fund’s return.

●

High Portfolio Turnover Risk. Portfolio turnover risk is the risk that when investing on a shorter-term basis, the Fund may as a result trade more frequently and incur higher levels of brokerage fees and commissions and cause higher levels of current tax liability to shareholders of the Fund. A portfolio turnover rate of 100% is considered to be high. The Adviser may engage in active trading, and will not consider portfolio turnover a limiting factor in making decisions for the Fund.

●

High-Yield Securities (“Junk Bond”) Risk. To the extent that a Fund invests in Underlying Funds that invest in high-yield securities and unrated securities of similar credit quality (commonly known as “junk bonds”), the Fund may be subject to greater levels of interest rate and credit risk than funds that do not invest in such securities. Junk bonds are considered predominately speculative with respect to the issuer’s continuing ability to make principal and interest payments. An economic downturn or period of rising interest rates could adversely affect the market for these securities and reduce an Underlying Fund’s ability to sell these securities (liquidity risk). If the issuer of a security is in default with respect to interest or principal payments, the Underlying Fund may lose its entire investment, which will affect the Underlying Fund’s and the Fund’s return.

●

Index Management Risk. To the extent the Fund invests in an Underlying Fund that is intended to track a target index, it is subject to the risk that the Underlying Fund may track its target index less closely. For example, an adviser to the Underlying Fund may select securities that are not fully representative of the index, and the Underlying Fund’s transaction expenses, and the size and timing of its cash flows, may result in the Underlying Fund’s performance being different than that of its index. Additionally, the Underlying Fund will generally reflect the performance of its target index even when the index does not perform well.

●

Industry or Sector Focus Risk. To the extent the Fund invests in Underlying Funds that focus their investments in a particular industry or sector, the Fund’s shares may be more volatile and fluctuate more than shares of a fund investing in a broader range of securities.

●

Large-Capitalization Companies Risk. The stocks of large capitalization companies as a group could fall out of favor with the market, causing an Underlying Fund and the Fund to underperform investments that focus solely on small- or medium- capitalization stocks.

●

Low Volatility Risk. Underlying Funds with investments in low volatility companies are seen as having a lower risk profile than the overall markets. However, a portfolio comprised of low volatility Underlying Funds may not produce investment exposure that has lower variability to changes in market levels. Investing in low volatility Underlying Funds may limit the Fund’s gains in rising markets.

●

Management Risk. The Fund is subject to the risk of poor selection in Underlying Funds. The Underlying Funds may not perform as well as expected, and/or the Fund’s portfolio management practices may not work to achieve their desired result.

●

Market Risk. The NAV of the Fund will change with changes in the market value of its portfolio positions. Investors may lose money. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. Although the Fund will invest in Underlying Funds that the Adviser believes will produce less volatility, there is no guarantee that the Underlying Funds will perform as expected. The prices of securities held by the Underlying Funds may decline in response to conditions affecting the general economy, overall market changes, local, regional or global political, social or economic instability, and currency, interest rate and commodity price fluctuations.

●

Mid-Capitalization Companies Risk. The stocks of mid-capitalization companies that the Underlying Funds may invest in may be subject to more abrupt or erratic market movements than stocks of larger, more established companies.

●

New Fund Risk. The Fund is a newly organized, diversified management investment company with no operating history. In addition, there can be no assurance that the Fund will grow to, or maintain, an economically viable size, in which case the Board of the Company may determine to liquidate the Fund.

●

Opportunity Risk. As with all mutual funds, the Fund is subject to the risk of missing out on an opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

●

Small-Capitalization Companies Risk. Small-cap companies that the Underlying Funds may invest in may be more volatile than, and not as readily marketable as, those of larger companies. Small companies may also have limited product lines, markets or financial resources and may be dependent on relatively small or inexperienced management groups. Additionally, the trading volume of small-cap company securities may make them more difficult to sell than those of larger companies. Moreover, the lack of an efficient market for the securities may make them difficult to value.

●

Underlying Funds Risk. Investing in Underlying Funds may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses. The Fund’s investment performance and its ability to achieve its investment objective are directly related to the performance of the Underlying Funds in which it invests. The risk of owning an Underlying Fund generally reflects the risks of owning the underlying investments the Underlying Fund holds. The Fund may incur brokerage fees in connection with its purchase of ETF shares. In October 2020, the SEC adopted certain regulatory changes and took other actions related to the ability of an investment company to invest in another investment company. These regulatory changes may adversely impact the Fund’s investment strategies and operations.

Performance information for the Fund is not included because the Fund had not commenced operations prior to the date of this Prospectus. Performance information will be available once the Fund has at least one calendar year of performance. The Fund’s past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future and does not guarantee future results. Updated performance information will be available on the Fund’s website at www.sgiam.com.
