Investment Objective

The investment objective of the SGI Enhanced Nasdaq-100 ETF (the “Fund”) is to seek capital appreciation and current income.

Fees and Expenses

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 Shares.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment):

Annual Fund Operating Expenses	SGI Enhanced Nasdaq-100 ETF SGI Enhanced 100 ETF Shares
Management Fees	0.98%
Distribution (12b-1) Fees	none
Other Expenses	none	[1]
Total Annual Fund Operating Expenses	0.98%

Example

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:

Expense Example	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years
SGI Enhanced Nasdaq-100 ETF | SGI Enhanced 100 ETF Shares | USD ($)	100	312

Portfolio Turnover

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. No portfolio turnover rate is provided for the Fund because the Fund had not commenced operations prior to the date of this Prospectus.

Principal Investment Strategies

The Fund is an actively-managed exchange-traded fund (“ETF”) that, under normal market circumstances, seeks to achieve its objective by (1) investing at least 80% of its net assets (including borrowings for investment purposes) in equity investments of companies that, at the time of investment, are included in the Nasdaq-100® Index (the “Index”) and/or options or futures, ETFs or options on ETFs that seek to replicate the returns of the Index (the “80% Policy”), and (2) investing in options strategies that seek to generate current income. The Fund’s equity investments may include common stock, preferred stock, warrants, securities convertible into common stock, futures, forwards, and options.

An option is a type of derivative instrument that gives the holder the right (but not the obligation) to buy (a “call”) or sell (a “put”) an asset at an agreed-upon price (“strike price”) prior to a specified date (“expiration date”) in the near future. A call option gives the purchaser of the option the right to buy, and the writer (seller) the obligation to sell the underlying asset at the strike price at any time prior to the expiration date of the option, regardless of the market price of the underlying asset. A put option gives the purchaser the right to sell, and the writer (seller) the obligation to buy the underlying asset at the strike price at any time prior the expiration date of the option, regardless of the market price of the underlying asset.

A call option is considered out-of-the-money if the market price of the underlying asset is trading below the strike price of the call. A put option is out-of-the-money if the market price of the underlying asset is above the put’s strike price.

An option premium paid to the writer (seller) is in consideration for the writer (seller) undertaking the obligation to sell (in a call option), or to buy (in a put option) the underlying asset, under the options contract.

The Fund uses an actively traded put and call options strategy that writes/sells options with deep out-of-the-money strike prices generally having an expiration date within 1-7 days to generate income. The Fund seeks to provide an “enhanced” yield compared to traditional option-based strategies. It does this by frequently selling short-term options (typically less than one week in duration) to generate income. Options that expire within 1 - 7 days and that are deep out-of-the-money exhibit a greater tendency to expire worthless and help avoid additional costs to the Fund of needing to close out the options contracts through repurchasing them at a higher price. Thus, it is more likely that the Fund would be able to collect the entire premium of the options sold.

The Fund’s options selling strategy seeks to provide income using exposure to the value of the Index and other broad benchmark indices such as the S&P 500^® Index and the Russell 2000^® Index. The Fund will consider factors such as liquidity, demand, premiums, and volatility in writing options against various broad benchmark indexes. The Index is a market-capitalization weighted index comprised of the securities of the 100 of the largest non-financial companies listed on The Nasdaq Stock Market LLC based on their market capitalization. Such securities may include companies domiciled domestically or internationally (including in emerging markets), and may include common stocks, preferred stock, warrants, securities convertible into common stock, and depositary receipts representing interests in non-U.S. companies. The Index excludes companies that are classified in the “Financials” group by the Industry Classification Benchmark, a product of FTSE International Limited. As of March 28, 2024, the Index had significant exposure to companies in the Technology and Consumer Discretionary sectors. The Fund will not concentrate its investments (i.e., hold more than 25% of its total assets) in a particular industry or group of industries, but the Fund may have significant exposure from time to time to companies in particular industries similar to the make-up of the Index.

The S&P 500^® Index is an unmanaged index composed of 500 common stocks, classified in eleven industry sectors, which represent approximately 80% of the U.S. equities market. The S&P 500^® Index assigns relative values to the stocks included in the index, weighted according to each stock’s total market value relative to the total market value of the other stocks included in the index. The Russell 2000^® Index is an unmanaged index that consists of the 2,000 smallest companies in the Russell 3000^® Index and represents approximately 7% of the total market capitalization of the Russell 3000^® Index.

Since the Fund writes/sells options with deep out-of-the-money strike prices, the Fund’s options contracts are intended to provide current income from option premiums. The Fund is subject to limits on the potential gains from selling options contracts to the premiums it collects as a result of the nature of the Fund’s options selling strategy. When the Fund sells an options contract it collects a premium as the seller. When the Fund holds a contract until expiration the premium collected is paid to the Fund. This process creates additional income to the Fund. The Fund may need to purchase or buy the same options contract based on market movements of the underlying indexes to avoid a loss or lock in a loss. This purchase or buy is meant to close out the options contract position, either locking in a gain or loss, based on the price received from when selling the options contract compared to the price paid for when purchasing the same options contract.

The Fund intends to enter into derivatives or other transactions, including options contracts, that provide leverage, in compliance with Rule 18f-4 under the Investment Company Act of 1940, as amended (the “1940 Act”). The Fund is expected to be a full derivatives user under Rule 18f-4, and has adopted policies and procedures for investing in derivatives and other transactions in compliance with Rule 18f-4. Limits or restrictions applicable to the counterparties or issuers, as applicable, with which the Fund may engage in derivative transactions could also limit or prevent the Fund from using certain instruments.

In addition to its options investments and equity investments, the Fund may hold short-term U.S. Treasury securities for collateral for the options, and to generate income.

The Fund may invest in securities of non-U.S. companies including, without limitation, common stocks, preferred stocks, warrants to acquire common stock, securities convertible into common stock, and American Depository Receipts (“ADRs”). The Fund defines non-U.S. companies as companies (i) that are organized under the laws of a foreign country; (ii) whose principal trading market is in a foreign country; or (iii) that have a majority of their assets or derive a significant portion of their revenue or profits from businesses, investments or sales, outside of the United States. The Fund may also invest in other registered investment companies, including ETFs (which may or may not be managed by the Adviser (“Underlying Funds”), to the extent permitted by applicable law and subject to certain restrictions. The Fund primarily invests in large-capitalization companies, but may invest in or have exposure to companies of any size within the limits of the Fund’s 80% Policy.

In seeking to achieve its investment objectives, the Fund may engage in trading of portfolio securities that may result in a high portfolio turnover rate.

The Fund may also seek to increase its income by lending 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”).

While the Adviser intends to fully invest the Fund’s assets at all times in accordance with the above-mentioned strategies, the Fund reserves the right to hold up to 100% of its assets, as a temporary defensive measure, in cash, eligible U.S. dollar-denominated money market instruments, or cash equivalents, including short- or intermediate-term U.S. Treasury securities, as well as other short-term investments, including high quality, short-term debt securities, and make investments inconsistent with its investment objective. The Adviser will determine when market conditions warrant temporary defensive measures. Accordingly, during such periods, the Fund may not achieve its investment objective.

SGI Enhanced Nasdaq-100 ETF | Risk Lose Money [Member]

You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments.

SGI Enhanced Nasdaq-100 ETF | Affiliated Fund Risk [Member]

• 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.

SGI Enhanced Nasdaq-100 ETF | Common Stock Risk [Member]

• Common Stock Risk. Investments in common stocks 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.

SGI Enhanced Nasdaq-100 ETF | Convertible Securities Risk [Member]

• Convertible Securities Risk. Securities that can be converted into common stock, such as certain securities and preferred stock, are subject to the usual risks associated with fixed income investments, such as interest rate risk and credit risk. In addition, because they react to changes in the value of the equity securities into which they will convert, convertible securities are also subject to the risks associated with equity securities.

SGI Enhanced Nasdaq-100 ETF | Counterparty Risk [Member]

• Counterparty Risk. Some of the derivatives entered into by the Fund are not traded on an exchange but instead will be privately negotiated in the over-the-counter market. This means that these instruments are traded between counterparties based on contractual relationships. Relying on a counterparty exposes the Fund to the risk that a counterparty will not settle a transaction in accordance with its terms and conditions because of a dispute over the terms of the contract (whether or not bona fide) or because of a credit or liquidity problem, thus causing the Fund to suffer a loss. A counterparty defaulting on its payment obligations to the Fund will cause the value of an investment in the Fund to decrease.

SGI Enhanced Nasdaq-100 ETF | Cyber Security Risk [Member]

• 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 investment 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 and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests 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.

SGI Enhanced Nasdaq-100 ETF | Derivatives Risk [Member]

• Derivatives Risk. The Fund’s investments in derivative instruments including options, forward currency exchange contracts, swaps and futures, which may be leveraged, may result in losses. Investments in derivative instruments may result in losses exceeding the amounts invested. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments, higher price volatility, lack of availability, counterparty risk, liquidity, valuation, and legal restrictions.

SGI Enhanced Nasdaq-100 ETF | Dividend Paying Securities Risk [Member]

• Dividend-Paying Securities Risk. A company issuing dividend-paying securities may fail and have to decrease or eliminate its dividend. In such an event, the Fund may not only lose the dividend payout but the stock price of the company may fall.

SGI Enhanced Nasdaq-100 ETF | Equity Markets Risk [Member]

• Equity Markets Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stocks and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers.

SGI Enhanced Nasdaq-100 ETF | E T F Risk [Member]

• 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,” “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 (“AP”) 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 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 net asset value (“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 Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares 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 Shares.

o Cash Transactions Risk. Unlike certain ETFs, 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.

o Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, the 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 Fund’s 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.

o 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. There is a risk that market prices for Fund Shares will vary significantly from the Fund’s NAV. Where all or portion of the Fund’s underlying securities trade in a foreign market that is closed when the market in which the Fund’s Shares are listed is open for trading, there may be changes between the last quote of the underlying securities’ value in the closed foreign market and the value of such underlying securities during the Fund’s domestic trading day.

SGI Enhanced Nasdaq-100 ETF | Futures Risk [Member]

• Futures Risk: The successful use of futures contracts draws upon the Adviser’s skill and experience with respect to such instruments and are subject to special risk considerations. The primary risks associated with the use of futures contracts are (a) the imperfect correlation between the change in market value of instruments held by the Fund and the price of the futures contract; (b) possible lack of a liquid secondary market, and possible regulatory position limits and restrictions for a futures contract and the resulting inability to close a futures contract when desired; (c) losses caused by unanticipated market movements, which are potentially unlimited; (d) the Adviser’s inability to predict correctly the direction of securities prices, equity indices, interest rates, currency exchange rates and other economic factors; (e) the possibility that the counterparty will default in the performance of its obligations; and (f) if the Fund has insufficient cash, it may have to sell securities from its portfolio to meet daily variation margin requirements, and the Fund may have to sell securities at a time when it may be disadvantageous to do so.

SGI Enhanced Nasdaq-100 ETF | High Portfolio Turnover Risk [Member]

• High Portfolio Turnover Risk. 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.

SGI Enhanced Nasdaq-100 ETF | Inflation And Deflation Risk [Member]

• Inflation and Deflation Risk. Inflation risk is the risk that the value of assets or income from investments will be worth less in the future as inflation decreases the value of money. As inflation increases, the real value of the Fund’s shares and any distributions thereon may decline. Inflation rates may change frequently and significantly as a result of various factors, including unexpected shifts in the domestic or global economy and changes in economic policies, and the Fund’s investments may not keep pace with inflation, which may result in losses to the Fund’s shareholders. Deflation risk is the risk that the prices of goods and services in the U.S. and many foreign economies may decline over time. Deflation may have an adverse effect on stock prices and the creditworthiness of issuers and may make defaults on debt more likely. If a country’s economy slips into a deflationary pattern, it could last for a prolonged period and be difficult to reverse.

SGI Enhanced Nasdaq-100 ETF | Large Cap Companies Risk [Member]

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

SGI Enhanced Nasdaq-100 ETF | Large Shareholder Risk [Member]

• Large Shareholder Risk. Certain large shareholders, including APs, may from time to time own a substantial amount of the Fund’s shares. There is no requirement that these shareholders maintain their investment in the Fund. There is a risk that such large shareholders or that the Fund’s shareholders generally may redeem all or a substantial portion of their investments in the Fund in a short period of time, which could have a significant negative impact on the Fund’s NAV, liquidity, and brokerage costs. Large redemptions could also result in tax consequences to shareholders and impact the Fund’s ability to implement its investment strategy.

SGI Enhanced Nasdaq-100 ETF | Leverage Risk [Member]

• Leverage Risk. Leverage amplifies changes in the Fund’s NAV and may make the Fund more volatile. Derivatives may create leverage and can result in losses to the Fund that exceed the amount originally invested and may accelerate the rate of losses. There can be no assurance that the Fund’s use of any leverage will be successful. The Fund’s investment exposure can exceed its net assets, sometimes by a significant amount.

SGI Enhanced Nasdaq-100 ETF | Liquidity Risk [Member]

• Liquidity Risk. Some securities held by the Fund, including options contracts, may be difficult to sell or be illiquid, particularly during times of market turmoil.

SGI Enhanced Nasdaq-100 ETF | Management Risk [Member]

• Management Risk. The Fund is subject to the risk of poor investment selection. In other words, the individual investments of the Fund may not perform as well as expected, and/or the Fund's portfolio management practices may not work to achieve their desired result.

SGI Enhanced Nasdaq-100 ETF | Market Risk [Member]

• 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 stocks the Adviser believes will produce less volatility, there is no guarantee that the stocks will perform as expected.

SGI Enhanced Nasdaq-100 ETF | New Fund Risk [Member]

• New Fund Risk. The Fund is a newly organized, 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 Directors (the “Board”) of The RBB Fund, Inc. (the “Company”) may determine to liquidate the Fund.

SGI Enhanced Nasdaq-100 ETF | Non Diversification Risk [Member]

• Non-Diversification Risk. The Fund is non-diversified. Compared to other funds, the Fund may invest more of its assets in a smaller number of companies. Gains or losses on a single stock may have greater impact on the Fund.

SGI Enhanced Nasdaq-100 ETF | Non U S Issuers Risk [Member]

• Non-U.S. Issuers Risk. Securities issued by non-U.S. issuers carry different risks from securities issued by U.S. issuers. These risks include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability, regulatory and economic differences, and potential restrictions on the flow of international capital.

SGI Enhanced Nasdaq-100 ETF | Options Risk [Member]

• Options Risk. An option is a type of derivative instrument that gives the holder the right (but not the obligation) to buy (a “call”) or sell (a “put”) an asset in the near future at an agreed upon price prior to the expiration date of the option. The Fund may “cover” a call option by owning the security underlying the option or through other means. The price and value of options can be highly volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including its anticipated volatility, which are affected by national and international fiscal and monetary policies, the time remaining until the expiration of the option contract and economic events, and their use can result in loss if the Adviser is incorrect in its expectation of price fluctuations. The value of the option contracts in which the Fund invests are substantially influenced by the value of the Index, and the Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless.

SGI Enhanced Nasdaq-100 ETF | Other Investment Company Risk [Member]

• Other Investment Company Risk. To the extent the Fund invests in other investment companies, including money market funds and ETFs, its performance will be affected by the performance of those other investment companies. Investments in other investment companies are subject to the risks of the other investment companies’ investments, as well as to the other investment companies’ expenses. An ETF may trade in the secondary market at a price below the value of its underlying portfolio and may not be liquid. An actively managed ETF’s performance will reflect its adviser’s ability to make investment decisions that are suited to achieving the ETF’s investment objectives. A passively managed ETF may not replicate the performance of the index it intends to track.

SGI Enhanced Nasdaq-100 ETF | Price Participation Risk [Member]

• Price Participation Risk. The Fund employs an investment strategy that includes the sale of out-of-the-money put option contracts, which limits the degree to which the Fund will participate in increases in value experienced by the Index over the call period (typically, one day, but may range up to one week). This means that if the Index experiences an increase in value above the strike price of the sold put options during a call period, the Fund will likely not experience that increase to the same extent and may significantly underperform the Index over the call period. Additionally, because the Fund is limited in the degree to which it will participate in increases in value experienced by the Index over each call period, but has full exposure to any decreases in value experienced by the Index over the call period, the NAV of the Fund may decrease over any given time period.

SGI Enhanced Nasdaq-100 ETF | Referenced Index Risk [Member]

• Referenced Index Risk. The Fund invests in options contracts that are based on the value of the Index (or in ETFs that track the Index’s performance). This subjects the Fund to certain of the same risks as if it owned shares of companies that comprised the Index or an ETF that tracks the Index, even though it does not.

SGI Enhanced Nasdaq-100 ETF | Sector Risk [Member]

• Sector Risk. To the extent the Fund invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors.

o Technology Sector Risk. In addition to market or economic factors, companies in the information technology sector and companies that rely heavily on technology are particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition.

o Consumer Discretionary Sector Risk. Companies in the consumer discretionary sector can be significantly affected by the performance of the overall economy, interest rates, competition, consumer confidence and spending, and changes in demographics and consumer tastes.

SGI Enhanced Nasdaq-100 ETF | Securities Lending Risk [Member]

• Securities Lending Risk. The Fund may lend portfolio securities to institutions, such as certain broker- dealers. The Fund may experience a loss or delay in the recovery of its securities if the borrowing institution breaches its agreement with the Fund.

SGI Enhanced Nasdaq-100 ETF | Tracking Error Risk [Member]

• Tracking Error Risk. The performance of the Fund and its 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.

SGI Enhanced Nasdaq-100 ETF | Temporary Investments [Member]

• Temporary Investments. The Fund may depart from its principal investment strategy in response to adverse market, economic, political or other conditions by taking a temporary defensive position (up to 100% of its assets) in cash, cash equivalents and all types of money market and short-term debt securities. The value of money market instruments tends to fall when current interest rates rise. Money market instruments are generally less sensitive to interest rate changes than longer-term securities. If the Fund were to take a temporary defensive position, it may be unable to achieve its investment objective for a period of time.

SGI Enhanced Nasdaq-100 ETF | U S Government Obligations Risk [Member]

• U.S. Government Obligations Risk. While U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. Government, such securities are nonetheless subject to credit risk (i.e., the risk that the U.S. Government may be, or be perceived to be, unable or unwilling to honor its financial obligations, such as making payments). Securities issued or guaranteed by federal agencies or authorities and U.S. Government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. Government.

SGI Enhanced Nasdaq-100 ETF | Valuation Risk [Member]

• Valuation Risk. During periods of reduced market liquidity or in the absence of readily available market quotations for the holdings of the Fund, the ability of the Fund to value its options contracts becomes more difficult and the judgment of the Adviser, as the Fund’s valuation designee, employing the fair value procedures adopted by the Board of the Company, may play a greater role in the valuation of the Fund’s holdings due to reduced availability of reliable objective pricing data. Consequently, while such determinations may be made in good faith, it may nevertheless be more difficult for the Fund to accurately assign a daily value. In the event an investment may need to be fair valued, the valuation involves subjectivity and there is a risk that the Fund may not be able to sell an investment at the price assigned to it in accordance with the Company’s policies and procedures in accordance with Rule 2a-5 of the 1940 Act (“Rule 2a-5”).

SGI Enhanced Nasdaq-100 ETF | Warrants Risk [Member]

• Warrants Risk. The purchase of warrants involves the risk that the Fund could lose the purchase value of a warrant if the right to subscribe to additional shares is not executed prior to the warrant's expiration. Also, the purchase of warrants involves the risk that the effective price paid for the warrant added to the subscription price of the related security may exceed the value of the subscribed security's market price such as when there is no movement in the level of the underlying security.
